40 Members’ Weekend 41 Restructuring of the SCOPE framework 44 Farewell from the third-year and master students 46 Farewell from the SCOPE | Vectum board of 2016 - 2017


Word of the President Dear Econometricians, What a year! Many of you probably haven’t realised yet that summer is just around the corner, but the academic year and our board year has almost come to an end. This will therefore also be my last word of the president. A new (academic) year brings new opportunities, but also new challenges. Most master students will start working, and they will exchange their flexible uni schedules for a more strict working life schedule. The current third-year students will probably start their masters, either in Maastricht or somewhere else. But let’s be honest – their hearts will always stay with us in Maastricht! For the second-years a semester full of adventures and new experiences lays ahead: your study abroad semester! I hope you all will have a great time wherever you go and I’m already looking forward to hearing all your stories after Christmas! Enjoy it to the fullest and don’t worry about anything that’s not worth worrying about! Finally, all of you first years who survived the year can be proud of yourselves – it really is an achievement to make it to the second year.

and social activities. The academic activities included a research lecture in every main block, the LaTeX workshop together with SCOPE | Economics and the master and PhD information evening with the KE Department. Furthermore, we supported the first years during their math courses through extra tutorials and we coorganised the second Maastricht Workshop on It has been an honour and a pleasure for me to Advances in Quantitative Economics by Alumni be the president of SCOPE | Vectum during this of the Econometrics and Operations Research academic year, and I will be leaving the board programme. As for the professional activities, with a crying and a laughing eye. Crying because our yearly Business Trip took place at the end this truly amazing year is coming to an end of the first semester, closely followed by the and laughing because I made lots of memories LED (Landelijke Econometristendag or National I wouldn’t have wanted to miss. It is time for Econometrics Day), which was successfully change and I can proudly say that I have fullest organised by Kraket and VSAE. Furthermore, four confidence in the proposed board consisting of companies came to our yearly Case Day in April Dominik, Marijke, Laura and Lorenzo. It has been and I was very happy we could welcome some an enriching and great year for us and for SCOPE alumni back in Maastricht for this. Lastly, we | Vectum and I would like to reflect on this time visited APG and the Smart Services Campus in in the word of the president. Heerlen and our students could find out what it is like to work at their data science department. During the year we mainly focused on three I hope all of these events helped you in getting types of activities, namely academic, professional 4


a better orientation about what you might want to do after your studies. Last but not least, the social activities make up a large part of our events. I would like to give a special thank to Lea and her activities committee for organising really fun Tuesday nights as well as a successful Members’ Weekend and coming up with new activities such as the City Game, trampolining and playing indoor beach volleyball. Furthermore, we went on another Ski Trip this year, which was greatly appreciated by the participants. We also continued the joint drink with the KE Department during the resit week in June and it was great to see so many students and KE department staff members mix and mingle. Finally, the Members’ Weekend took place last week to round off the semester, which was like the finale of a great year and I’m probably not wrong when I say that everyone of us had a little post-membersweekend depression. Next to all of this, the SCOPE restructuring was on top of our agenda this year. We had many (long) meetings about how to make SCOPE more attractive to students. Eventually, this led to a proposed merger of SCOPE Maastricht, SCOPE | 3MA, SCOPE | Economics and SCOPE | FOCUS. A summary of the process and SCOPE | Vectum’s role in this will be available later in this PerVectum.

a recap from all activities we have done during the past block, starting with the Ski Trip in April and ending with our Members’ Weekend in June. Furthermore, you can read about Claudia’s and Laura’s Exchange in Canada and Sweden and find out more about our professor Vincent Kreuzen and Vectum alumni Kaya, who is currently doing her PhD in Rotterdam. Maybe you have already heard about the myth of the Vectum Kissing Tree? If you would like to see Operations Research applied in real life, you can read the full-depth analysis about the Kissing Tree. If that article inspired you to conduct your own research, you will find all information on how to publish your first academic article in Alexander Heinemann’s article. Finally, not only we are sad seeing our master and some third-year students leaving us, but they are (at least) equally sad that they have to leave Maastricht. In “Farewell from the third-year and master students” they share their favourite memories of their time as a student in this beautiful, little town.

Lastly, I would like to invite all of you to our GMA on June 26that 19:30h. It will take place in the Aula, H0.01, at SBE. This is your chance to hear from each member of the board what we have achieved throughout the year. We will talk you through the financial position, what activities we organized, our liaisons with companies and different aspects of our public relations. The I’d like to take the opportunity and thank all our restructuring process of the SCOPE framework active members for making those events possible. and SCOPE | Vectum’s position will be part of the Besides, I’d also like to thank each and every one of discussion, too.

Ski Trip written by Koen Steeghs Following the tremendous success of the first ski trip last year, SCOPE | Vectum decided to organise another ski trip this year! After a long and harsh week of studying for exams we finally left on Friday, April the 8th. Led by travel agency Husk, we headed towards the French Alps with a group of 16 people. Guided by the ski trip committee and the two charming bus drivers we were ready to get the party started. For me it was the first time that I joined the ski trip, however, in the bus it soon became clear to me that I was surrounded by a bunch of advanced skiing, snowboarding, and après ski enthusiasts. The good vibes started off right away: the first beers were consumed, the PerVectum was distributed, the puzzles were solved, and some good old memories were shared from last year’s ski trip.

Room”, and a real “Men Cave Room”. Although, every night we gathered in one room to party together! We rotated rooms as our main concern was to still get our deposit back from the hotel at the end of the week.

However, after all these great parties, early mornings followed at which we tried to get the first chairlift or gondola that would bring us even higher into the beautiful mountains. For Marijke, Merit and Dominik it was the second time they were skiing, therefore they first went to their skiing lessons in the mornings. Also for Lukas it was his second time skiing, yet he did not possess any fears and he used his Italian skiing style and twists to conquer some black slopes with the advanced group skiers. It was actually Lorenzo’s first time skiing, therefore we skied together the first two days, so I could teach him some tips and tricks. After having struggled for a while Lorenzo also “mastered” the skiing skill. These private skiing lessons cost him a lot of energy, therefore he went back to the residency in the early afternoons. For the “Newbies Room” this was a blessing, as he took on the role of our After a night of travelling we finally arrived in our personal chef during the trip and he prepared skiing area ‘Val Thorens’, which we would explore many delicious meals for us. Such as pancakes for for the rest of the week. On site we received breakfast, extremely tasty hamburgers, spaghetti some additional info with regards to our stay and and numerous other meals for dinner. On this the availability of activities organised by Husk. year’s ski trip we had to cook our own meals, We took our luggage to the lobby and for some which gave us a lot of freedom to decide what of us the skiing fun already began, since they had we wanted to do instead of having to go to the ski passes that allowed them access on Saturday restaurant at set times. Yet, two times we decided already. The others still had to wait a day, but this did not really matter, because the weather was absolutely great. 23° Celsius on a height of 2300 metres, how was that even possible? This sunny weather made our beers taste even better. After a somewhat exhausting day we finally got access to our residency. The room division was already decided upon including a “Rotterdam Room”, “3 Boardies Singles + Mr. Winterball”, “Newbies 6


to go out for dinner with the entire group and most of us used this opportunity to enjoy typical French meals such as cheese or meat fondue or Raclette. As Lorenzo was often busy preparing our meals in the afternoons, I had some time left to practise my aggressive skiing style when joining the advanced skiers group. Together we conquered plentiful slopes and descended infinite long snow tracks. At the end of such a day it was time to descend some mogul slopes, this was not everyone’s best skill, but it resulted in a lot of fun.

On Wednesday, after having enjoyed some beautiful skiing days, Lorenzo had improved his skills enough to join the advanced skiing group. After about two hours of skiing Lorenzo and I decided to take another route and meet the others down in the valley again. Thus far, the group did not know we had secretly prepared a plan to surprise them. Before we went on the trip we had ordered a pretty weird skiing suite. So while the others were waiting in the valley, they suddenly noticed a skiing dinosaur coming down the slopes, which caused a lot of laughter. In the afternoon we were together with a bunch of people and we had lunch at a height of 3200 meters on one of the many large glaciers in the Trois Vallées area. This day, most of us stopped skiing a little earlier than usual to watch a Champions League match that night. A group of soccer hooligans took off to the Shamrock pub to watch Bayern München loose with 2 – 1 against Real Madrid. The Germans, however did not stay sad for too long as the next morning it turned out to be great skiing weather once again. Maybe it had even been a little too hot as in the afternoon the snow turned into some form of slush puppy.

Moreover, during the skiing trip, a tradition had been started by some advanced skiers demonstrating a new trick or challenge every day. The others were invited to get out their comfort zones and duplicate the tricks; this resulted in some cool activities and very funny bloopers. Examples of exercises included individual pirouette skiing, partner pirouette skiing, skiing on one leg (this was not meant to be for everyone), fake falling while continuing to ski and finally four men long polonaise skiing. Unfortunately, we did not tape any exercises, but if we had done so, funniest home videos would have another full show to broadcast! Friday was already our last skiing day and after a week of having taught Lorenzo I felt excited to cover the entire skiing area in one day. Since I was already familiar with the Trois Vallées area, I decided to guide a group of advanced skiers through the entire skiing area. We left Val Thorens for Orelle and then continued to Courchevel. In Courchevel there are two so-called ‘vertical experiences’ of which unfortunately one was closed due to bad snow conditions. Luckily, the slope named the ‘Grand Couloir’ was still opened. This slope had to be reached via a narrow icy trail which already discourages most skiers. Subsequently we arrived on a slope with an angle of inclination of 75% and at some points even 85%. Everybody made it down safely, yet full of excitement or adrenaline and after

descending this impressive slope we decided to take it slow and move back towards Val Thorens. We ended this amazing day in the La Folie Douce, one of the most well-known après ski places in France, sadly this après ski bar closed at 17:00, so we continued the party in the “3 Boardies Singles + Mr. Winterball” Room. This Friday night the skiing trip still almost failed or as some Dutch would say ‘walked into the water’. This literally happened as the dishwasher in Merit’s, Lea’s Marie’s and Lukas’ room suddenly started to flood. Fortunately, we found out quickly and worked together as one big team to solve the problem.

started recovering from the fantastic week, enjoyed the sun and the wonderful views over the mountains, or played some table tennis in the luggage room. At the end of the day we had our final dinner together in a hipster burger place, after which we were ready to sit down in the bus to start our journey back to Maastricht.

All in all, it was an amazing and memorable week with great people. Everybody enjoyed themselves doing what they did best, be it skiing, snowboarding or après skiing, everyone made the most of their time. No matter how advanced you were in skiing or snowboarding, the trip was a great success. Finally, I would like to thank the After a great week of skiing, most of us quit on ski trip committee and inform them that I will Saturday while a small group still used the time definitely join the third SCOPE | Vectum ski trip left to cover some slopes. The rest of the group edition next year!

Research Lecture and Pub Quiz by Actuarieel Genootschap

On Tuesday, 18th of April, Eric Beutner held the last research lecture of this academic year in the field of Actuarial Sciences. The topic was risk measures and how to estimate them. Legislators all over the world enforce capital requirements for risk management of financial institutions and business entities, especially after the financial crisis of 2007/08. Calculating capital requirements is based on risk measures such as Value-at-Risk and Expected Shortfall. During the research lecture, Beutner gave an insight into the basic properties of these risk measures and how they can be estimated, in particular how they can be estimated non-parametrically. Afterwards, we headed to the Ma van Sloun for a Pub Quiz held by Actuarieel Genootschap. During the company presentation we had the chance to learn more about the job as an actuary, whereas during the Pub Quiz everyone could show how much of an actuary is already inside him or her. After a fair fight, Emiel had proven that he has what it takes to be an actuary. Triumphantly, he accepted his prize. Congratulations!

Eating with Eccentric Econometricians Lederhosen, Lager and Lukas (AKA Mr. Winterball)

Name: Born in: Study: Favourite Drink: Favourite Book: Fav. Vectum Activity:

On a bright and sunny Saturday afternoon, three members of the PR committee decided to invite themselves over to Lukas’ place for a fantastic feast and some good conversation. Unfortunately, Lukas’ roommate needed to study (who even studies in week 4?). Lorenzo, esteemed entity of the PR team and soon-to-be Treasurer, offered us his place so that the festivities could still go on! As this was the first interview/dinner combination not on a weekday, it seemed that everyone from the PR committee had a similar idea and decided to bring along one (or multiple) bottles of wine to the bountiful banquet.

were trying to chip away at the stupendous sea of wine we started the night with.

After the food had settled in our stomachs somewhat, we decided to get started with the “interview”. I’m sure if you’re an avid reader of the PerVectum, you understand the routine by now; the food was put away, the drinks poured, recording started and I was once again left taking notes. Lukas first started the evening off by telling us it was probably going to be a big mistake to be drinking red wine, as all of his hilarious drunk stories start with red wine. With this in mind, we started listening intently to the stories Lukas was For dinner, Lorenzo started us off with some telling us, while at the same time continuously incredibly filling and deliciously nutritious taking more sips of our wine. appetizers, Mojitos. Unfortunately (or fortunately, depending on how you see things), Lukas started us off by telling us about how much Lukas had also decided to bestow upon us a he loves to travel.

All the while we their time on the island they started sleeping in 10


shifts so that someone could safeguard the food. Last summer Lukas flew to Australia from Dublin, as the flights from Dublin were much cheaper. While in Dublin, Lukas decided to take the time to appreciate some of the local Irish culture in the form of visiting pubs and drinking, and so had spent his two nights in Dublin on cultural outings. When it was time to go to the airport, Lukas took the bus only to find that the bus driver stopped in the middle of the route because his shift had ended. With all of the passengers looking on bewilderingly, the bus driver left the bus at the stop and walked his way home. Luckily, another bus driver came along soon enough in order to bring everyone to the airport, and Lukas did not miss his flight.

at the time. About four days before he was set to leave back to Germany after a three-week holiday, the airline called him up to tell him they could finally deliver the bag to him via a cab. At the end of their holiday, Lukas was now at the airport with two suitcases, and the airline wanted to make him pay for the additional bag. Of course Lukas was not about to let that happen, and explained the story to the desk agent who, upon calling her supervisor and looking into the situation, allowed him to check in his second piece of luggage for free. Lukas concluded the story with a beautiful moral: If your suitcase gets lost, just complain a lot and then you’ll get a bunch of free stuff.

At this point, the PR committee decided to take At the airport everything went well, he checked advantage of the vast amounts of alcohol we had his luggage in and boarded the flight on time. at our disposal, and decided to play some drinking Having arrived in Australia, knocked out from a games with Lukas, as a bonding experience.

Case Day written by Carien Leushuis

I cannot believe how fast the year is flying by. It is already April and therefore several companies are heading to the southernmost city in the Netherlands for the annual Case Day hosted by SCOPE | Vectum. To make sure that we are all on the same page, the Case Day is a day where SCOPE | Vectum invites four different companies to provide an introduction about themselves by means of presentations and a case study in their field of operation. The day was split into a morning and afternoon session with lunch at the restaurant Reube in between. Whether interested in Econometrics, Actuarial Sciences or Operations Research, the day offered something for everyone. This year Kleynen Consultants and Bright Cape were starting off the day, both having prepared an interesting case. Kleynen is a consultancy company for insurance companies and pension funds located in Heerlen. They enthusiastically introduced their new project to build a fully automated and online insurance company available to everyone anytime, called HiThere. How can we turn a sad face into a happy face is the motto of their operation, which is also visible on the facade of their building in Heerlen. Bright Cape is a consultancy company specialised in offering services in the field of business analytics, optimisation, machine learning, data

visualisation, risk and project management. The case was about categorising emails with the help of machine learning algorithms. After the winners for the first round of cases were announced it was time for lunch at restaurant the Reube. The girls in particular were very grateful as the Reube is located just down the road at the Tongersestraat. The cobblestone streets in Maastricht look very charming but are not really made for wearing heels. The lunch consisted of a soup and salad, catering for all tastes. After a great lunch, we returned to the SBE continuing the second round of cases. This time it was Districon and Inergy presenting. Districon is a consultancy firm in the field of logistics. The case was about supply chain management and submitting orders for several products. While Districon’s focus is on solving problems in the field of Operations Research and optimisation of supply chain and logistics networks, Inergy operates in the Data Science and Big Data industry. We were given a dataset including sales of cafes at five different locations and we were asked to come up with a new concept at one of these locations. Be creative they said and that is what we did. After an interesting day full of new impressions, it was time to head down to the Preuv for an informal drink.


Indoor Beach Volleyball On the 25th of April, it was time to get a taste of summer! Even though it was still cold outside, we went to the tropical city Heerlen to play indoor beach volleyball! Some people already had the summer feeling and took the touristic way to Heerlen after missing some exits on the highway. Nevertheless, everyone arrived safely and the summer vibes could start! Jeroen was well prepared with his Hawaiian shirt, and with the heaters on, it almost felt like being in Hawaii! While enjoying the sand and the music, everyone started playing beach volleyball, which was a lot of fun. Some balls were flying around and ended up completely in the wrong direction, while others were smashed so hard that some nice diving skills were shown to catch them. Besides playing beach volleyball, some of us started playing soccer and frisbee. In between the two hours, it was time for a break with some nice drinks and some time to relax. After the break, we played for another hour, before heading back to Maastricht. This time we took a planned detour via de McDonalds where we enjoyed some welldeserved chicken nuggets and hamburgers. We then drove back and continued the night in the Ma van Sloun!

Claudia’s Exchange in Montréal For my exchange semester, I decided to go to the Université de Montréal in Montréal, Canada. I made this choice because it was a chance for me to discover the North American lifestyle and to study in French. Moreover, I have wanted to live in Canada for a while as Canadians have a reputation of being friendly and open-minded and this city is very special. Hopefully, this little article will give you some insight on the Canadian lifestyle.

The university was very different from Maastricht as it did not have PBL but mostly lectures. The classes I took were more economic related: Economic Development, Economics of Social Behaviour, Contemporary Economic Issues, Database Management and Financial Institutions. Economics of Social Behaviour was definitely my favorite course, it was a mixture between basic econometrics and facts as seen in “Think Like

14

a Freak”. The courses are taught in French, but if you do not speak French, there are 6 other universities in Montréal and most of them are English-speaking. Regarding the exams, there are two sessions of one week each (in October and in December) which are pretty stressful but all in all doable. The teachers were from Canada, Africa, Belgium and France and the majority interesting as some of them were working for big companies and others for the Canadian government. Since exchange students cannot move on campus, I decided to rent a flat with three other people. The rent was close to what I pay here in Maastricht (around 450 euros) and we soon realized that our place was one of the best flats compared to other exchange students’ places (and I am not biased at all). Moreover, our neighbours were exchange students as well, so we organized some pretty nice house parties. It is easy to meet international students as there are some organizations that plan trips and activities for us. However, it is not the same story with locals. The Canadian students were really nice, but very serious about their courses and were therefore not very social in class.


I really liked the atmosphere of the city: it is very green, there are tons of nice cafes, crazy brunches, ... Each neighbourhood has its own typical style: Downtown, the Old Town, Mile-End, where the Hassidim Jewish community lives among young students and entrepreneurs; le Plateau, where French people live; the Gay Village, with all the bars and clubs; and more. My favourite part of the city were the people, everyone is super openminded and genuinely nice, I learned a lot from them over the span of 5 months. Also, Montréal is very international, people there come from all around the world and consequently, the language is interesting and basically “Frenglish”.

I really wanted to discover Vancouver. The first trip I did was to a National Park, Mont-Tremblant. There are plenty of great parks in Canada and I wish I could have visited more. I went there with three of my friends, we rented a car for almost nothing (super cheap and super easy) and we slept at a B&B right next to a lake. We did a few hikes with great weather and enjoyed a nice evening at the lake. Next on my list were San Diego and Vancouver: visiting these two cities in 10 days was a challenge, though. First, I went down to Ocean Beach for five days, a small beach town in San Diego, where I got to enjoy the sun, got (super) sunburnt and ate (a lot) of Mexican food. If you ever go to San Diego, make sure you go to Ocean Beach (and to the USA hostel there), it is the best! Afterwards, I went up to Vancouver with Chris. The city is really diverse and it is possible to see downtown and in an hour get out of the city and find yourself on top of the Grouse Mountain with a beautiful view all the way to Vancouver Island. After my finals, we headed to Belize and Mexico for two weeks. Going from Montréal where it was snowy and -20 degrees to the Mexican weather was pretty intense but it was nice to finish the exchange experience at the beach.

One of the main reasons why I chose Montréal as my exchange destination was that its location is great. It is close to the Niagara Falls, New York, Boston, Ottawa and lots of other cool cities. However, as I travelled along the east coast of the US already I wanted to see a bit of California and 15


How to publish your first academic article?! Alexander Heinemann Getting your first academic paper published can be a challenge. It should be said upfront: a thesis (Bachelor or Master) is not yet a publishable article and the way to get there is an academic jungle with plenty of pitfalls. Therefore, I would like to navigate you through the wilderness by sharing my personal experiences with you on how to publish your first article. Let’s start at the beginning: the most crucial ingredient is, of course, a research idea. Indeed, it requires a seed in order to grow a tree. Some of you already faced the issue of finding a suitable topic for your thesis, while the vast majority settled with a subject that has been suggested to them. With the overwhelming literature it seems difficult to get an innovative idea in order to say something new even though the definition of ?innovative? is stretchable. Sometimes it helps to read published articles for inspiration. Having found a (thesis) topic? Great! The next step is to get your ideas to paper either by hand or electronically. Structure is crucial, so you better start planning. Which model would you like to use or adapt? Which problems still need to be solved? How to obtain data? It is wise to make a time schedule to ensure you are on track. Having a first draft ready? It is time for the next phase: editing. Did you stumble over a sentence again and again while rereading some paragraph? You may want to change that one. Is the current table the best way to summarize your results? Can you improve on your notation? Are your sections coherent? Edit your work intensively until you are completely satisfied. Don’t settle for less, but strive for excellence! When you are fully content with what you typed, the circulation phase starts. Inform people about your results and give presentations of your research. For the Bachelor and Master thesis you are typically asked to present your topic. See it as an opportunity to get a first response and be open to criticism. Besides, writing slides helps you to focus on the main message. What shall the audience take home from your presentation? Another excellent opportunity to communicate your work to the academic world is attending conferences. Talk with other academics about your topic and gather as much feedback as possible. Back from the conference, incorporate the comments and suggestions into the paper. Some researchers go several times back and forth between the presenting and the editing stage until they are fully content. Once you have rigorously polished your paper, your work is ready to send it to the journal. The twist is to select and target an appropriate journal for your work. There is a large spectrum of journals out there, especially in econometrics, and strategic selection can save you a lot of time and effort. Journals differ not only by subfields, 16


but also by quality, scope and several other characteristics. Clearly, you don?t want to send a technical paper to an applied journal. No clue which journal matches best to your paper? Ask people who know the metier. Your thesis supervisor would be natural to ask. Besides he/she already knows your paper. Maybe there is a special issue forthcoming where your article fits perfectly in. Journal targeted? Before submitting your piece of art, carefully read the guidelines of the respective journal including the maximum number of pages and the requirements for citation formatting. Referees always look for straightforward criteria for rejecting a paper. So don’t give them any reason. Make sure you include a marketing introduction using phrases like ”we provide a novel approach...”. In the end, you want to sell your paper. Now comes the moment of truth. Do you get rewarded for the hard work over the last months (or year(s))? Once submitted, you cannot do anything except for waiting. How long? That depends on several factors: the journal, the editor, the referees (and potentially their holiday plans), etc. Typically, the longer you have to wait, the better, meaning that the referees did not find any straightforward criteria to turn down your work. I didn’t know this back then. In fact, I waited several months for a reply seriously considering to contact the journal’s editor for asking whether they actually received my work. Did you eventually get a response? A rejection is often the first step to acceptance. The editor may initially turn down your article on the basis of the referees report, but can offer you the opportunity to resubmit a revised version that addresses the referees? comments. My advice: take their suggestions seriously. Your aim is to please the editor and the referees such that it is difficult for them to say no a second time. When resubmitting to the journal, attach responses for the referees and editor, in which you show your appreciation and elaborate on their comments and the changes you have made accordingly. The key is to be super-nice, positive and polite. Carefully choose your wording and employ phrases such as ”We have done our best to improve the presentation of the results in Section ...”. The first revision is extremely important and decides whether your paper is on a clear path to (likely) acceptance. An important note: wait at least one or two months before resubmitting your revised version. Otherwise you run the risk of signalling that you did not put enough effort in the revision. The referee revision process can go into several rounds. If you look back now to your initial draft, you probably do not recognize the paper anymore due to the changes you made along the way. In the end you hopefully receive a letter with the words: ”Your paper entitled .... has been accepted for publication in the journal ...”. Congratulations! 17

WORLD CHAMPIONSHIP OF ECONOMETRICS, AND WE WERE THERE!!! written by Frederique van Leeuwen and Rick van Dael Dear fellow nerds, Together with two of the most outstanding PhD candidates in the world - Yuliya Shapovalova and Sean Telg -, we (see picture) were the lucky ones to attend this super prestigious championship. Just to give you some extra understanding about what we were actually doing there, please read the following. Every year, the University of Amsterdam is hosting the Econometric Game, also known as the World Championship of Econometrics. The participating universities are expected to send delegations of four students majoring in econometrics or relevant studies with a maximum of two PhD students. The teams will be given a case study with a certain theme, which they will have to resolve in two days. After these two days the ten teams with the best solutions will continue to day three. This year the general theme was: Crime & Safety. The corresponding case revolved around questions concerning crime preventive behaviour, focussing on the use of roll-down shutters in The Netherlands.

our expertise. However, this absolutely didn’t stop us from working our asses off and dive into a new field of data analysis, namely spatial data analytics. It sounds more cliché than we want it to sound like, but we can absolutely conclude that we learned a lot in these two days of hard work. Besides making The Netherlands a bit safer, we also had a lot of fun! Even throughout the case, we always had time to joke around, although we were exhausted by the end of it (see picture).

Unfortunately, all our hard work and innovative machine learning implementations were not rewarded, as we did not make it to the final. However, this meant that we could go party in Amsterdam! At night, we always had nice dinners, we were placed at tables without our teammates, so we could socialize with the smartest people on the planet, such as PhDs from Harvard, Oxford or Illinois. On our first party night, we could witness each other’s singing skills while doing karaoke, followed by an amazing performance on the dance floor by us all. On the last day, we had a day off in Amsterdam because we were basically losers. We did a hangover city tour, and at night we had to admire the finalists’ presentations. Although we were expecting a lot from the This was again followed by a nice dinner and a theme, once we heard the topic of the case, big party with all the other teams. we were quite disappointed. We are convinced that there are plenty of other exciting things Overall, we are extremely grateful for this amazing concerning crime and safety to investigate, such experience, both on academic and social level. If as terrorism and data privacy, than predicting you want to see us shine on National Television when The Netherlands will be saturated with roll- or hear our angelic (…) voices on The Radio, then down shutters.

Escape City

It looked to be a stormy and rainy evening in the small town of Maastricht when an ensemble of Econometricians split into teams to help Lea crack the code of the Vectum safe. Lea, after a night of drinking heavily at the Annual SCOPE Framework Cantus, had forgotten the code to the safe containing all the beer cards. Luckily for her, the econometrics entourage was willing to help out. Splitting up into five teams, they were given tedious tasks ranging from constructing sound strongholds to playing challenging charades, from guessing snazzy songs their teammates were singing whilst gargling water to an incredibly demanding variation of twister (See picture). After the successful completion of each task, they were given two cryptic clues; one leading them to their next destination, another revealing one part of the combination. After a stressful evening for Lea, wondering whether the beer cards were doomed to be lost forever, a glimmer of hope sparked in her mind as she saw one of the teams running towards her on the far horizon. They had cracked the code, the exclaimed. After recounting their adventures for the night and sharing their sharp solutions with Lea, Lea anxiously entered the combination they had found. As Lea entered the last digit of the combination, she was met with a satisfying click as the lock opened. The victors noted the look of relief on Lea’s face as she saw that the beer cards were indeed intact and well, they could drink at the Ma van Sloun once again! With all of the other groups called back to the Vrijthof and everyone’s minds at ease, Lea decided to reward all the diligent econometricians for their valiant effort by using up all of her recovered beer cards. Lea now knows better, as she stores the code in a very safe place somewhere in the office, not just in cryptic puzzles scattered across the city. Hopefully she passes this story on to her successor, so that the beer cards of the econometricians will never be at risk again.

Brewery Visit written by Koen Steeghs and Lorenzo van de Laar Can you think of something more fun than visiting a brewery on the year’s first sunny day? If you can, just stop reading… If you can’t, you will surely enjoy reading about our guided tour through ‘Stoombierbrouwerij de Keyzer’. The brewery, located in the Wycker Grachtstraat, had an authentic courtyard in which we gathered for our tour. We split up into one English and one Dutch speaking group.

Our first stop was at the first floor, where the guide told us about the basics of brewing and the history of the brewery. We all got to see some malt and barley, which was “very” exciting. We could not wait any longer to taste the beer, but unfortunately we still had to go see some more floors. Next, we went to the third floor, where they used to clean the raw barley. Our guide explained that the barley was delivered in bags of 100kg at the station and that unemployed people were paid with beer, gin, food and two and a half guilders to carry those bags up to the third floor. After the third floor, we went to the fifth one. Here they used to dry the barley. Our guide invited us to feel the wind blowing between the windows. Sadly, only the chosen ones could feel it, which probably had to do with the nice weather. Next, we went to the second floor, where the barley would soak for 40 hours, after which it would sprout on the first floor. When the barley hits its optimal level of enzymes, the process is stopped, and the barley, which gets roasted on the fourth floor, will be called malt from now onwards. The malt got stored in a silo.

After seeing the silo, we were finished with the malt-process, next-up was the brewing-process. For this, we entered another building, with a huge copper kettle outside. We saw the mill that crushed the malt in action. Furthermore, we saw some kettles, some cooling system and the small bottling plant. Our guide explained everything about the mixing with the water and hop, and the cooling, but unfortunately, we cannot remember that anymore, because everyone was extremely focused on not falling off the old wooden ladder, which also was still its original state.

However, we do remember the tour through the villa of the brewery’s owner. We saw the kitchen, the study, the dining room, the bathroom and the bed room. We saw some fancy furniture, a collection of rare porcelain, and a dovecote. The bar was connected to the villa, so at last we would get our beers. We all gathered for some chatting, while enjoying some beers. First, we got a blonde beer, then we got a dark beer, accompanied with snacks. The beer was so good, that some even ordered some more. After the end of the tour, we went to the Ma van Sloun, for, guess what…? Some more beer and to hit the dancefloor of course!

Applied Operations Research: A full depth analysis of the Vectum Kissing Tree

1

Introduction

As you might know, one of the most important tasks of the board is to keep track of the SCOPE | Vectum Kissing Tree. In this undirected (in some cases there might have been a directed intention though) graph, the board indicates if there has been exchange of saliva (or more body fluids, although it is not their intention to keep track of that) between two Econometricians by a single line. A multi-directional arrow indicates a (former) relationship between the persons involved. This article aims to provide a full depth analysis of the Kissing Tree. Firstly, it states a full description of the graph, secondly, the key observations and their implications as well as proofs are presented. Finally, some suggestions for further research are given.

2

Description

First of all, despite its name the Kissing Tree is actually not a tree. Therefore, we define the Kissing Tree to be a graph G = (V, E), where V represents the vertices (people) and E the edges (connections between the people). We have |V | = 62 and |E| = 47. Furthermore, E is the union of R and K, where R is the set of edges indicating a (former) relationship and K is the set of edges indicating a ”simple” kissing connection (well, maybe even more, who knows?). Namely, E = R ∪ K, where |R| = 18 and |K| = 29. Hence, we define the Relationship Tree as G∗ = (V, R). Even though Vectum promotes itself as a ”connected” community, the graph G itself is not connected. As mentioned earlier it is also not a tree, but due to recent break-throughs in research it has also been proven that it is no longer a forest (a disjoint union of trees), which it used to be for the 22 years of Vectum’s existence. For further explanations on how that myth has been dissovled, please refer to section 3.2 THE Cyle. According to the latest version before publication, the graph G consists of 16 subgraphs. 22


3 3.1

Key observations Longest connected (relationship) subgraph

The most striking observation of the Kissing Tree is its longest connected subgraph which consists of 11 vertices and 10 edges in total. The special attribute of this subgraph is that one of its subgraphs (so basically a ”sub-subgraph”) is the longest connected relationship subgraph of G*. It consists of 3 vertices.

3.2

THE Cycle

The moment, which was highly anticipated by all Econometricians, finally arrived during the last edition of the Vectum Members’ Weekend. For years, students have been speculating about the kissing connections that still had to be made to complete Vectum’s first cycle within the Kissing Tree. Even though many bets have been at stake, nobody predicted the outcome of this lottery correctly. Luckily, we can say now that we finally have an even cycle with 4 vertices in our graph. In that way, one of the current boardies was able to leave a great legacy before handing over the reigns.

3.3 3.3.1

Degrees of the vertices Maximum degree

We can define a subset W (winner) ⊂ V of people with the highest degree (number of connections). The highest degree within the Kissing Tree is equal to 3. As the cardinality of W is 5, there is not a clear winner among us. Though, there seems to be a group of people who tend to be an element of W; 3 out of 5 are former or current boardies. 3.3.2

Handshaking Lemma

For people who are not familiar with the Handshaking Lemma, here a quick definition: Lemma 1. Let G = (V, E) be a graph and let dv (v ∈ V ) denote the degree of vertex v. Then  dv = 2 |E| v∈V

In more colloquial terms, at a great Tuesday Vectum night, several Econometricians shake hands with each other. The number of Econometricians that shake an odd number of hands is even. According to the Handshaking Lemma, we know that the sum of the degrees over all vertices is equal to 2 |E| = 2 ∗ 47 = 94. By further calculations, we find that the average person in the Kissing Tree has kissed 1.5 people. 23


3.4

Bipartite

Lemma 2. The Kissing Tree is bipartite. (A graph is called bipartite, if the set of vertices can be partitioned into two disjoint subsets V1 and V2, i.e., V 1 ∪ V 2 = V and V 1 ∩ V 2 = ∅ such that every edge has one end point in V1 and the other in V2.) Proof. The proof is left as an exercise to the reader. (Hint: Think about the minimum number of colors needed for a feasible coloring. Additionally note that even though statistically, 7% of the world population is homo- or bisexual, the Kissing Tree does not display any homosexual connections.)

4

Further research and suggestions

Referring back to section 2, the outcome of our intense analysis shows that 15 is the minimum number of kissing connections needed to make the graph connected. If we even want to go a step further and aim for a complete graph (spread the Vectum love) we need in total 1844 additional kissing connections. If we would like to achieve an odd cycle in the Kissing Tree, we need at least one homosexual kissing connection, though this would imply that the graph is no longer bipartite, a fact, that the attentive reader of course noticed while completing the proof in section 3.4. Another suggestion, we would like to pass on to the new board, is to include a rating of the kissing experience as a weight for each edge, namely ce ∈ [1, 10], where 10 is the highest possible rating. This will allow for an even deeper analysis, especially regarding shortest path and minimum cost flow problems.

5

Conclusion

The Kissing Tree does not yet reflect what SCOPE | Vectum promotes to be. Improvements regarding the longest connected path or the maximum degree are still possible. Though, we are glad to see that the first-mile stone has been laid by establishing the first cycle within the Kissing Tree. We do believe that the next academic year has lots of romantic possibilities for our members in store and we are excited to see how the proposed board (which is hardly represented in the Kissing Tree yet) implements our suggestions. The current board has done their best they could. 24

Laura’s Exchange in Gothenburg, Sweden For all students, the study abroad is probably the most exciting part of your studies. Going to an amazing location to experience all the different cultures of this country is an experience of a lifetime. For me, this amazing location was Gothenburg in Sweden; the city of Volvo, the FrÜlunda Indians ice hockey team, and the fish church. The first thing people always say when I tell them that I went to Sweden is that it probably was extremely cold there, which is true for most of Sweden, but not for Gothenburg. It is located at the west coast and in the south of Sweden, giving it a climate quite similar to Maastricht. But enough about the weather.

of the historic center. The courses I took were Mathematics, Portfolio Investments, Corporate Valuation, and The Swedish Model and Equality (being an exchange course). The quality of the courses were all great, and the teachers had a true passion in what they were teaching. At the university, there was also a student union called IntU, that was responsible for taking care of the exchange students. They had many activities planned for the exchange students, with one of my favorites being the scavenger hunt to get to know the city. Also, every Wednesday the pub at the university was open, so all exchange students came together then to party the night away (and drink cheap beers)!

Gothenburg is the second largest city of Sweden, but even though it is big, I felt at home from the first day I arrived. On that first day, I was picked up from the airport by this amazing pick-up service that the university provided. They had busses going to different campus-like housing facilities, dropping you off wherever you got your room. I decided to get a room via the university, because it is very difficult to find a room on your own, since there is a huge housing shortage throughout Sweden. Plus, the campus where I stayed was only a few tram stops away from the university and the city center, and had a lot of facilities like ping pong tables, barbeque spots, a gym and a sauna.

The city itself is a very beautiful city, and there are many things to do. For example, there is Scandinavia’s largest theme park Liseberg only 5 minutes away from the center. Also, many small islands are scattered right in front of the coast, called the archipelago. It is perfect to go there for a nice hike in nature, or a swim in the sea (in summer). There is also a huge park which is perfect for a picnic, barbeque, or a run. It even has a small zoo where you can pet a moose. There are also many activities that you can do, like go to an ice-hockey game, or go out to eat with friends.

The university was located in the middle of the city. It was a modern building right in the middle 26


The reason why I chose to go to Sweden was because I’ve never been to Scandinavia before and I wanted to experience the culture there. The swedes are actually quite shy in the beginning. It can take a lot of effort from your side to truly get them out of their shells. But when they do, they are suddenly very open, enthusiastic people. Also, Swedes are more relaxed than Dutch people. They take half-hour “Fika” breaks three times a day which basically entails drinking coffee and eating a cinnamon bun. Life is very tough in Sweden.

trip to Stockholm and Oslo. All these trips were absolutely amazing, and each city had so much to offer. One experience that I will never forget is going on a husky sled tour, while seeing the Northern Lights. That is a phenomenon that I have never seen, and nothing can ever compare.

All in all my exchange experience was a great one. The highlights of my exchange however, were I have been able to explore parts of the world all the trips that I did during my exchange. that I have never seen before, and meet amazing Gothenburg has the perfect location to travel new people. I can definitely recommend anyone throughout Scandinavia and to visit all the capital to go to Gothenburg in Sweden. cities of the surrounding countries. It takes 3 hours by bus to go to Oslo, 3 hours by bus to go to Copenhagen, and 3 hours by train to get to Stockholm. Gothenburg also has its own airport, making it really easy to travel anywhere else around Europe. The trips that I did were going on a road trip to the middle of Sweden, going to Lapland, doing a boat trip visiting Tallinn, Saint Petersburg and Helsinki, and going on a city 27


Inhouse Day at APG Heerlen written by Marc Glowienke On Friday, May 12th, this year’s Inhouse Day took place at APG in Heerlen. A group of 20 econometricians ranging from second years to master students and one student from the Department of Knowledge Engineering met at the train station in Maastricht early in the morning. After a 20-minute train ride and a lengthy discussion between Christian and Jeroen, whether we took the fast or slow train, and a quick walk through the “beautiful” Heerlen, we arrived at the APG building. We were welcomed by Maartje, an alum from the Econometrics program in Maastricht and some more people from the data scientist team. First, there was the opportunity to grab some coffee or tea, which some badly needed. After that, the day proceeded with a company presentation, lunch, the case and finally the drinks. During the presentation, we got some information about APG in general and then more specifics about the job as a data scientist at AGP, explicitly we heard about some projects the young team is currently working on. On our way to lunch, we also got a quick tour through the Smart Services Campus where the university and companies are connected with each other. During the typical Dutch lunch with some “broodjes” we had the possibility to talk to the employees accompanying us and learn more

28

about what it is like to work at APG. After everyone was finished, we went back to the APG building and got the laptops for the case. The case was about which pension should be paid, if a limit on income is introduced. Our objective was to identify the target group the marketing department should focus on given a specific income limit. We got some prepared data and a R code to predict the income. The data could be analysed using the handy program PowerBI to make some quick graphs. Every group had a busy hour trying to get the most out of the data, which worked out for some but not so much for others. My group got quite lucky, since we discovered that the graphs are connected and hence we could show more relations between the data; for example, the amount of hours woman work and their marital status. We also managed to improve the fit of the R code to the model and together with a convincing presentation, we won the case. Feedback was shortened, since beer was waiting for us, but we got a nice APG water bottle as present. After a couple beers, we headed back to Maastricht. From my point of view, it was an interesting day and big thanks to APG for making this possible. Also, a big thanks to Jeroen and Maartje for organising this day.

They decide that they must split in groups of two based on their preferences. The first duo will drink red wine at the wine bar, the second duo will drink white wine at the wine bar, the third duo will enjoy the restaurant’s Italian cuisine, and the last duo will have a long conversation about their travels in Australia, while enjoying some Kangaroo steak. A waiter then informs them that it is the restaurant’s policy that: Only two people, who have (at least) 3 nationalities combined can sit together in the restaurant. After some time, the group figured out how to split. They all sat down and had a good time. The next day Fred discovers that he brought the wrong jacket back home. He took the jacket of the person he sat with the day before. With whom should Fred meet up to change jackets? • This puzzle is based on true information. • Start with figuring out who have multiple nationalities. • Those who will eat Italian, consider some Italian dish as their absolute favorite dish. • Those who drink wine also drink their absolute favorite.

Meet the Professor

An interview with Vincent Kreuzen

Can you tell us a little bit about yourself? You know a lot of Dutch people get annoyed by foreigners when they refer to The Netherlands as Holland, but I am actually never bothered by it, because I am actually from Holland. I did my Bachelor and my Master in Computer Sciences in Utrecht. After that I applied for a PhD position in Maastricht, because there was none available in Utrecht. Luckily, I got accepted. I already started teaching as a student assistant in Utrecht and continued during my PhD here in Maastricht. I always really enjoyed it, so after my PhD I started working as a full-time lecturer. This is now my second year. Last September I also took on an half-time position at the Zuyd Hogeschool, University of Applied Science, in ICT, which is taking me back to my roots in Computer Science. Next September, I will leave Maastricht University and take on a job in Den Bosch. Did you ever consider working in the private sector? Yes I considered it, especially because I studied Computer Sciences and everybody knows that you can make a shit-ton of money with that, but after my Masters I was not sure what to do yet. I started university when I was 16 years old, so I was also relatively young when I graduated, so I thought: let’s first do a PhD first and then figure out what I want to do. How does it come that you started university at the age of 16? I started university at the age of 16, because I started high school when I was 10 years old. I skipped 2 years in elementary school, as I was already fluent in English at the age of 6. When I started teaching as a student assistance, I never told my students my actual age, because some of them were older than me.

32

What do you enjoy about teaching? There are two things you can enjoy about your job. It’s either feedback and appreciation or money. I don’t care too much about money as long it’s sufficient. Appreciation in research is only happening after you publish something, but the journey till you publish something is a long one. Whereas with teaching you notice that people learn something new during every single tutorial which is a great form of appreciation. You are actually doing something that matters. This sounds super cliché, but you are able to educate a generation to do awesome things. You told us that you were in the board of your study association in Utrecht? Which position did you take on? Yes, I was the Commissioner Internal Affairs and Vice - Commissioner External Affairs. Therefore, I was supervising every single committee in the


study association and as Vice – External I also went to companies to arrange the funding. Before my time as a boardie, I was active in many committees. I think study associations are an important aspect of your student life. That is why every time SCOPE | Vectum asks me for help, I am really happy to contribute. Which skills that you learned during your board year, do you still benefit from? First of all you need to realize that especially as a Computer Scientist every single company wants to work with you as soon as you have accomplished a board year. You learn so many important skills during your board year, for example problem solving skills. Before my board year I always let others solve my problem, but during your board year you need to learn how to face these problems yourself. What do you enjoy about supervising a thesis? The nice thing is to see a student grow. Usually when the students start they do not completely know what they have to do and then they start narrowing down their area, slowly finding their way, and at some point they hit the “AHHAAA I finally understand my thesis, yeyyy” – moment and I love that moment and then I am happy, because they are happy. What are your hobbies? I have two major hobbies. First, I like writing stories in science fiction and fantasy. Usually I only write in Dutch, but there is one story that I am currently writing in English. My fiancé is an artist and she is really into Batman. So I told her that I would write a Batman story for her and she started to make a comic out of it. For that we might have an offer to publish it, but it is not even close to being done. Second, I also develop board games. I made quite some already, but I really want to publish one of them. I am a mediocre drawer, but I have some designs in my head that I want to use for the game, but drawing them myself takes ages. So if you know a really good artist, let me know and refer them to me. What about your fiancé, can she not help you with the drawings?

She is actually really busy at the moment. She also writes. That’s actually how we met. That was actually one of our question: whether you met your fiancé while doing your hobby. Yes, we met through one of those online forums where you can write yourself but can also evaluate other people’s writing. What did you want to become when you were younger? At a very early stage I wanted to become a Cowboy or an astronaut like every young guy. But later on I quickly figured out that I wanted to do something academically, simply because I was relatively smart in every subject besides languages. The professors here in the KE – department seem to match a profile. No one enjoys languages and everyone met their significant other while doing their hobby. Well, I know something the other professor definitely do not have. I have three ducks at the moment. My fiancé works at the animal shelter once or twice a week. Shortly before King’s Day they took on 8 undernourished, little ducklings and my fiancé asked me to take care of them on King’s Day. Unfortunately, 5 of them did not make it, but 3 survived and you know, no one really wants to have ducks, so we took them home and trained them. They can now eat from my hand. My first pet in Maastricht was a big spider that lived outside my window, so I called the spider Toby (from Spiderman). One day, I heard a noise and when I turned around, I saw a bird flying away with my Toby in its mouth. That is how I lost my first friend in Maastricht. Finally, do you have any advice for our fellow students? Please realize that no matter how you look at it, you have so much more free time as a student than when you start working. Use that extra time. Do a board year. Travel. Enjoy. Next time you can do that you will be 70 years old. Thank you for taking the time! 33


Life after Vectum

PhD in Global Health Development at Erasmus University An alumni interview with Kaya Verbooy In the last two editions of the PerVectum, we featured two Vectum alumni who talked about their working experiences in the private sector. Obviously, it is not only possible to enter the job market with your university degree, but also continue to work in academia. Therefore, we would like to introduce you to Kaya Verbooy in this edition, who decided to switch her field of studies from econometrics to global health by pursuing a PhD in at the Erasmus University Rotterdam.

You said you did the one-year research internship, where did you do that? I first went to National University of Singapore, where I worked in the public health department. Afterwards I went to Geneva to the World Health Organization (WHO) to work on my paper for 2.5 months. It was about child vaccinations in Indonesia.

Do you still use the knowledge from your econometrics master during your PhD? Could you introduce yourself? It is closely related to the cross section and panel I am Kaya Verbooy, 25 years old, I am from data course taught by Denis Crombrugghe. I can Maastricht. I did both the bachelor and master apply the theory that I learned during the course program in econometrics from 2010 to 2015 at a lot now and sometimes I still use his slides if I Maastricht University. I moved to Rotterdam have a question. Other than that, I do not really after my studies. I like listening to music, reading use the knowledge, I learned during my studies. books and watching movies. What does your research focus on? What motivated you to pursue a PhD after you Usually if you work on topics in the field of health finished your masters? economics/econometrics there would be a grant, During my exchange at the University of Richmond, because these topics are most likely linked to I did a course in development economics which I pharmaceutics companies or the government. really liked, because my mom and dad are both In that case you would be hired for a project, from different development countries, although but that is not applicable for me. So currently, they have lived in Maastricht for a long time. My I do not know my exact research topic yet, but mom is from Indonesia, and my dad is half Indian I am starting to focus on health care facilities and Nepali. Already then, I had the idea to switch in Indonesia. Inequity is a huge problem within my fields. Therefore, I extended my masters with Indonesia. Even though the country has a steep a research internship. And that is how I eventually economic development, it is spread out over rolled into global health development. So now islands, provinces and many districts, therefore I am doing a PhD in global health. In general, I it is really hard to manage everything with a decided to pursue a PhD, because I wanted to population of 240 million people. One of my have a career which has a research component. dreams would be to go to Indonesia and collect Furthermore, it opens a lot of doors on the job my own data and since my co-promoter is market since many positions require you to also a development economist, specialised in have some kind of research degree. Moreover, I Indonesia, I hope it will be possible at some point wanted to do a PhD, since it provided me four in the future. extra years to learn about something completely different, I am interested in. Did you consider any other universities for your PhD (also outside The Netherlands)? As I was interested in economic health, I knew it 34


would be impossible to do the PhD in Maastricht. I kind of rolled into Rotterdam, since I was working there already as a junior researcher for a year. Additionally, in Rotterdam they give you four years instead of three for your PhD. It is a good institute and I hope, it will also open some doors later on in my career. I did not really look for universities abroad, since in The Netherlands you are considered as an employee, while abroad you are considered as a student. So, it takes a lot of more effort to get into the program and also to get the funding. Additionally, my boyfriend and my family live in The Netherlands and that is another reason, why I wanted to stay.

field the longer you stay in it, which means that your direct colleagues are scattered around the world. Therefore, it is always nice to meet the people that are working on the same topics as you.

Do you have a good working environment with your colleagues? Do you work closer together, or does everyone focus on their own project? Everyone does focus on their own project, but that is not specific to my work environment, but academic life in general. But we do have meetings to update each other. I think that within our subdivision the senior staff is really open, so it is very easy to talk to them during those meetings. You are working on your own paper, but you meet your thesis supervisor once a week or once a month.

The motivation is higher during you PhD than during your student life? I also enjoyed the bachelor and the master program, but sometimes there were courses that I did not feel like doing anything for, simply because I did not know how to apply the models, the professors talked about, in real life. But now with everything I learn, I know where to use it for and I am able to answer society relevant questions with it. To me that is a relieve. A lot of people of course go into econometrics, but that was not meant to be for me.

With reflection on your first year is there anything you like to look back on? Well not really in the past, but I am looking forward to this thing in the near future. I am going to a conference in Boston in July, that is going to be a lot of fun. I will be presenting my work there, so I hope some people will show some interest in what I am working on and I also hope to meet some interesting people. I think within academic life you get more experienced/specialised in your

Who would you recommend doing a PhD? That depends on the kind of PhD, since there are so many different types of topics. But the most important thing is that you have an interest in research, an interesting topic and are patient, because you have to keep working on it and be motivated for 4 years. During my bachelor and masters, I did not think I would do a PhD. But once I saw the opportunities within it, I found out, I really enjoy doing research, so I started

What do you like more and what do you like less as about being a PhD student compared to a regular student life? Basically, as a PhD student you still have the same freedom as a regular student. And if I wanted to, I could party every night, but you simply do not do that, since you have this strong conscious about your own project. You are not learning something, because other people want you to How does your daily working schedule look like? learn it, but you are learning, because you really That differs every day. We do not have a set time, want to learn it yourself. So, it is easier to invest when we have to be at work, but that is usually time in that. We all had this course in university, the case for an academic career. I usually arrive that we really hated. But I do not have that around 10, but then I also leave a bit later or anymore. Erasmus organizes a lot of social and sometimes really late when I am in the flow. It academic events like drinks, lunch or a seminar, also depends on whether I have to teach or not. which are always really nice to attend. At first you After work, I go to the Erasmus sports centre on might think that your PhD is an extension of your campus. Lunch in-between with colleagues is student life, but in the end, it turns out that it is also part of my regular working schedule. your job.

thinking that this could be the right fit for me. If you do not have those interest than do not do it. It is not for someone who wants to work from 9 till 5, since you are working more than 40 hours a week.

thus it is more than just you and your piece of paper.

After your vacation, conference and summer, what are your next steps for your research? I am almost done with writing my first paper, When did you noticed that you liked doing maybe I can write my 2nd paper from the same research? data set. We are merging different data sets. Let I noticed already during my master thesis, as I me give you a bit of background information on did my thesis with Antoon Pelsser. He is so smart Indonesia.

Waterskiing

SCOPE | Vectum’s Ski Trip: The Sequel, now on melted ice at an affordable price. written by Ori Porat Blessed by the best weather in 33 weeks, SCOPE | Vectum set out for the fabled ski pond, which was nestled deep within Belgium and only known to those who dared drive past The Filling Station. After a bumpy road trip, we arrived on site and gathered the necessary gear. With wet suits zipped, life jackets clipped, and helmets fastened, the econometricians were ready to give Jesus a run for his money. Most of us were complete beginners, however, this did not stop us from fearlessly – and quite literally – diving head first into the water. While kneeboards were available, water skis and wakeboards seemed to be preferred, probably because the kneeboards were of a desperate-actress-in-Hollywood level of easy, and the econometricians were up for the challenge. The experienced among us brought wakeboards of their own, and even managed to pull a few tricks off the scattered obstacles in the lake. Much like our study, the craft was utterly unforgiving: being slammed repeatedly into the water prompted a frustrating yet familiar kind of sorrow. Nonetheless, when the balance was found, the econometricians found themselves starring in a Coca Cola commercial, and the few minutes of bliss made it all worth it. Fortunately, no one was eaten by lake sharks or bitten by pond snakes.

End-of-the-year BBQ

For the last Tuesday activity of the year, we figured we’d bring it full circle and end with the same activity we started the year with. We had a barbeque, cooked up for us by Grillmeister Jeroen, and hosted at the wonderful place of Joost and Katherine. With a (new) pool filled with beers, enough food to feed a (Vectum) family, and 30 baguettes sliced up for us by the Activities Committee, the night was sure to be a success. Catering for Vegans, Vegetarians, Carnivores and everything inbetween, the Activities Committee showed us some of their logistical and forecasting prowess by ordering an almost perfect amount of everything, although maybe there might have been a bit too many baguettes… With around 45 people attending, this was one of our most popular activities of the year, and rightfully so as it was a very relaxed and fun night. After the majority of the food was cooked and consumed, some people formed little groups and decided to play some drinking games. We stayed at Katherine and Joost’s place until around 10:30, after which we headed to the Ma van Sloun for some additional drinks and more lively music, celebrating the proposed board for the academic year of 2017-2018.

Members’ Weekend written by Fred Hagelstein

40

With the academic year coming to an end, I could boil down what I’ve learned in my first year as an Econometrics & Operations Research student into two simple statements: there exists an element in the set of seasons such that on some days of the year, the probability of a rainy day in the Netherlands (surprisingly) approaches 0. (Corollary: we define this element in the season set as summer. Yes, the Netherlands has a summer.) And (ii) as the days of the year approach summer, time spent in the library approaches 0 hours and the need to celebrate after a long year increases exponentially. So it all boils down to this weekend in summer, June 16, 17, and 18. The moments we’ve shared with our fellow Vectumeers – often starting with an afternoon activity and ending on Wednesday mornings Tuesday evenings stumbling onto Tongersestraat – these moments served as a sneak peek to what we could expect from this year’s Members’ Weekend.

37 participants knew our mysterious weekend location. As we gathered to leave Maastricht together, Jeroen cleared the air. “We’re going to Gulpen!” As a first-time participant at Members’ Weekend, there was still so much I did not know. What will we do when we get there? How fun will it be? Who will make it back alive?

Older students got me excited. But also curious. Members’ Weekend is the Vectum’s final social activity of the year, where students from all years of the programme would, as the name suggests, spend the weekend together. First of all, there was asymmetric information w.r.t. where we would be going, only a few selected among the

Luckily, the German weather was sunny enough upon arrival for us to have BBQ for dinner as planned. The board introduced a mystery, whodunit game in which Stan used his knowledge from Game Theory courses to claim victory. We then continued with a pub quiz. As budding econometricians, some questions

Some of us naively accepted that we would be spending our weekend a bit closer to the Maas than hoped for. Yet little did I know that while the most of us were kicking off our weekend in Gulpen’s water park, Lea, Anne, and Marc were busy in Ammeldingen bei Neuerburg, a small German village close to Luxembourg, preparing to welcome over 30 incoming econometrics students. This is where we would actually spend our weekend. After a few fun hours of waterslides and whirlpools, we split our group into different cars, with each driver determined to find the shortest path from Gulpen to Ammeldingen.


implored us to flex our quantitative skills, such as “how many different nationalities are present at this weekend?” or “how far away are we from Maastricht?” Admittedly, the quiz was more comedic and tongue-in-cheek than it was mathematical, which came as a relief after some challenging exams. We then rounded off our first evening with some karaoke to tune our voices in preparation for Saturday evening’s Cantus.

Our lucky streak with good weather continued on Saturday, which was crucial for us to make the most of our daytime activity. After breakfast, we made our way to the Naturpark Teufelsschlucht, which means “the devil’s canyon” in German. This mountainous and rocky plateau offered an invigorating change from the flat Dutch plains. The park itself comprised several hectares of land where a now dormant volcano once erupted millions of years ago, thus leaving its surroundings teeming with some outstanding geological fine-tuning. For instance, some rocks would tower even over the trees. Deeper into the canyon, we could feel the temperature dropping, which can be refreshing when you’re outdoors during a summer day. Our guide also organised a treasure hunt for us that included bows and arrows, climbing, and hiking. We were equipped with some gadgets that could come in handy in the forest, such as a GPS, and a few clues and directions. Along the way, our two new friends Alex and Josh kept us company until we cracked all the codes and claimed our treasure. Alas, I won’t reveal what the treasure was – not to spoil the surprise for future participants.

has become a well-defined element of our Vectum Members’ Weekends. To make things a bit clearer for my fellow newcomers to the Netherlands, you can imagine a Cantus to look like an Oktoberfest celebration with mandatory singing. This longstanding tradition evokes an aura of camaraderie with a strict set of rules, but at Vectum we keep it rather relaxed. Nonetheless, our “Praesus”, Vice President Jeroen and Treasurer Lea, ensured that any unruly behavior would be punished. As an international group, we sang songs in Dutch, German, English and even Spanish, witnessing some remarkable performances throughout the evening. As the night went on, we went from sitting elbow to elbow to swaying arm in arm, rounding off a fun weekend with some good spirits. But the end of the academic year was not our only reason to celebrate. Two of our participants, Anne and the proposed Vice President Marijke, had their birthdays on this weekend. Although they received cake and gifts from friends, they were not immune to the Praesus’ verdicts. Bribery with cake was strictly forbidden.

Hunting for treasure got us thirsty, just in time for Saturday evening’s awaited Cantus. The Cantus is a venerated Dutch tradition that 41


After a few hours of sleep, it was time to clean up and head back to Maastricht. After my first Members’ Weekend, I can only agree with my fellow participants that our Board and Activities committee deserve a big thank you (THANK YOU) for topping off our year of memorable get-togethers with such an entertaining getaway. As a first year Bachelor’s student (and therefore first-time participant in the Members’ Weekend), this trip was great to bond with my fellow students from all years of the programme, away from the lecture halls and bookshelves. Although our upcoming courses after summer won’t be easy, there’s at least the next Members’ Weekend to look forward to once they’re all over. I encourage my fellow students, new and old, to tag along to this event next year!

Restructuring of the SCOPE framework

During the academic year 2015 / 2016, it was proposed that SCOPE | Economics and SCOPE | FOCUS would merge during the current academic year, since they would complement each other well. During the summer break, SCOPE, previously known as SCOPE Maastricht, proposed to join the merger. This resulted in restructuring ideas and discussions concerning the whole SCOPE framework, meaning the associations SCOPE | 3MA, SCOPE | Economics, SCOPE | FOCUS and SCOPE | Vectum, and the umbrella organisation SCOPE.

Research [E&OR] students as well and diversely as we do now. Furthermore, since E&OR is a very small part of SBE, the fear existed that our voice would not be heard in an overall association and that our students’ opinion might be disregarded in decision making, whether intentionally or not. Our members pointed out that they highly value the intimate contact to companies and alumni, where the close relationship to alumni follows a tight community through all years within SCOPE | Vectum. Additionally, the cooperation with the KE Department works that well because there is no overlap with other study tracks. Last but not least, During the fall semester 2016, we had lots of the LOES (national Econometrics association) talks and discussions about the goals of the highly requires SCOPE | Vectum being financially SCOPE framework, its intentions and areas which independent and being autonomous with regard need improvement. Specifically, we analysed to external responsibilities and decision making. where the SCOPE associations can collaborate and cooperate better both among each other Thus, following our members’ voice we did not and with the faculty. further continue any merger discussions but rather sought opportunities how and where to Even though the conversation started with cooperate.

Farewell from the Third-year and Master students What I am going to miss the most about my student life in Maastricht? Definitely the people that made it a fantastic time and hung out with many hours. Furthermore, I am really going to miss the flexibility of being a student: going to the pub on a Vectum Tuesday night and having a few beers (too much), waking up the next day in the afternoon and spending the rest of the day on the couch. Even though there are plenty of more (little) things I will miss, I still want to mention that I will never forget this amazing board year. Besides getting a lot of satisfaction by representing Vectum, (trying to) improve our association and getting to know a lot of people very well, my three fellow boardies (Lea, Marie and Merit) made this year truly unforgettable! With less than a week before the GMA, I feel like that I am going to miss them and the (leaving) Vectum members the most. Nonetheless, as this chapter of my life is approaching its end, it means a new chapter is going to start and I hope that these people will be included in that chapter as well! Jeroen Lamers After four years in Maastricht, and a nice Master of Science degree, it is time to move on to another phase in life. I had a great time, and will miss lectures and tutorials with my friends, and the pretty views you get while biking over the Maas. What I will not miss, is biking uphill the Tongersestraat to get to SBE though. My best Vectum memories are the ones from the Business Trips in January, and thus I can highly recommend going at least once before you leave Maastricht! Rick van Dael I usually associate places with people, so when I think of Maastricht I will always get reminded of the most beautiful memories I share with a group of amazing people. These people made Vectum, the Tuesday socials at the Ma, the chill nights at Eric’s place, the Business Trips and the Members Weekends an unforgettable chapter of my life. So I recommend the current members to enjoy and appreciate every moment, be open, experience, reach out, laugh, love and live. Ilina Dimitrovska After four great years studying in Maastricht, the end has come near. The experiences and moments gained in this little city will stay with me for the rest of my life. SCOPE | Vectum made my time even better and gave me the best memories. I will never forget the inspiring people from all over the world that I have met during the events and most importantly the free beers provided afterwards. All in all, I will always look back on Maastricht with a big smile. Stan Braakman

The four years that I have spent in Maastricht have been some of the best years of my life. From the different events organized by SCOPE | Vectum, I especially liked the Business Trip week. During this week you get to know your fellow students on a whole new level, and you have the opportunity to see how well they can present a case while they are completely hungover. Additionally, I really enjoyed the Tuesday events, especially the events that were combined with strolling around the city such as laser tagging in the park and the city sudoku. So, for any current student I highly recommend going to the Business Trip at least once and try to enjoy the Tuesday night events as much as possible, because before you know it, it will be your turn to leave Maastricht. Naomi Schippers 1. What I will miss about Maastricht: the ‘everything is in walking distance’ lifestyle, the park, St. Pietersberg, Limburger kindness, Chocomel + Vla, Achter de Molens, Table soccer in the Shamrock, Eric’s place, amazing people 2. What I will miss about Vectum: every form of social activity (Tuesday evenings, Members Weekend etc.), the geeky jokes, Ma and it’s never changing playlists, even more amazing people 3. What I can recommend every current student: don’t finish it ;), explore the area around Maastricht, open a proper club and a decent kebab store (so that I have some upgrades in case I return) Christian Wirths Looking back at the last four years that I spent at the SBE (while simultaneously not really being a true student of the SBE) I will miss quite a lot of habits. For example, spending very long days at the library, SSC or any room at TS53 in order to solve the assignment, we got this time. Vectum activities with free beer even though I started off my student life not being fond of beer at all but that turned around pretty quickly. As a final note I recommend you to enjoy your student life as long as you can and maybe think about applying for a Master’s exchange! Dewi Peerlings It’s the end of the second semester of 2017, which also marks the end of my time in Maastricht. The Members’ Weekend just took place and made me realize what a great time I have had with everyone I met over the course of the past three years. Choosing Maastricht for my bachelor is definitely a choice I won’t regret. I want to encourage everyone to make the most out of his / her time in Maastricht by enjoying the various terraces and the Burgundian lifestyle that you won’t find elsewhere in the Netherlands, because it’s over sooner than you think!

Farewell from the SCOPE | Vectum board of 2016-2017 As the academic year and therefore also our board year is coming to an end, it is time for us to say goodbye. We will be leaving the board with a crying and a laughing eye. It has truly been an enriching and great year for us and we will never forget the incredible memories we made. All things we did this year would not have been possible, without the input of many people and organizations. First of all, we would like to thank all our sponsors. Without them it would not have been possible to organize all the events we did this year. Furthermore, we would like to thank the other LOES associations for the great cooperation and the fun events we had together. Additionally, we are thankful for all the work we have done together with the SCOPE framework and the student representative, Jeroen Moonemans. Even though, the discussions were sometimes difficult, we still think they were very valuable for the cooperation and collaboration with SCOPE Maastricht and SBE in the future. Moreover, we would like to express our gratitude towards Leann Poeth, who helped us a lot regarding Vectum’s alumni relations. Furthermore, we are very grateful for the support the KE-department gave us throughout the year. Finally, SCOPE | Vectum would not be the same without its members. We are incredibly thankful for everything you have brought to SCOPE | Vectum this year. Without your input in various committees, we would have not been able to organize all the events we have done this year, regardless whether there are social, business or academic related. Thank you for joining us every Tuesday night and creating amazing memories with us. You made this year very special. It is time to hand over the reign to Dominik, Marijke, Laura and Lorenzo. We wish you the best of luck and success for next year. We have great confidence in you and we hope that you will be able to achieve all your goals. 46


We would like to wish you a happy summer and a relaxing time off!

The proposed SCOPE | Vectum board of 2017 – 2018 consists of: Dominik Dribusch – President Marijke Lijzenga – Vice President Laura van Vledder – Secretary Lorenzo van de Laar – Treasurer 47
