We will report a study of the formation of zeolitic imidazolate framework (ZIF-8) thin films on gold and silicon substrates. We employed solvothermal deposition as well as dip-coating from a colloidal nanoparticle solution in order to form thin, uniform films. Nanoparticle coalescence was observed to occur on both substrates over time, and thermal annealing of the thin films was explored as a way to control the coalescence process and explore thermal stability. Uniform, thin films were investigated further for interaction with CO2 using temperatureprogrammed reaction spectroscopy.

Blurring Borders: A Neighbor-Hood/Rise Plan for Downtown San Diego
Downtown San Diego is a growing urban environment with several overlapping and conflicting models for the urban neighborhood. Unlike traditional connotations of ‘neighborhood’ as a focal point of communal diversity and interaction, Centre City Development Corporation’s Neighborhood Planning Model has restricted the urban neighborhood into horizontal spaces of fixed building codes, single-use towers, and gridlocked, dead spaces. Unlike traditional models of neighborhood planning that create restrictive borders according to predetermined political lines, the urban neighborhood must be perceived as an exploded model, capable of occupying a single block. This revised neighborhood model, A Neighbor-Hood/Rise Plan, proposes to blur traditional urban neighborhood borders, turning the city on its side and perceiving the urban neighborhood through a revised vision of consolidation and separation. The Neighbor‘Hood’ is no longer a ‘covering’ or ‘enclosure’ of bounded space, rather the Neighbor-‘Rise’ model embraces the ‘vertical’ nature of the growing city, promoting unrestricted, open, and spontaneous neighborhood development.
Civil Society and Its Role in the Success of Democracy in Sub-Saharan Africa Jessica Berry Faculty Advisor: J. Michael Williams Department of Political Science and International Relations
This paper addresses the nature of the role of civil society organizations in the effectiveness and success of democratic Sub-Saharan African nations. African states are often weak due to their inability to influence or give representation to the lower classes. Civil society institutions give people incentives to participate such as a sense of belonging and the ability to socialize their members into the values of democracy. This paper seeks to examine the success of democratic states in terms of their survival, the actions of their leaders in regards to respecting election results, and the ranking of freedom designated to them by the organization Freedom House in correlation to the status of their civil society organizations. The definition of civil society will be that of a population of solidaristic groups which form for collective purposes in the political space between the state and the populace. This definition includes faithbased organizations in order to contextualize the reality of civil society in African cultures as opposed to the normative western definition of the concept. The focus of this research will be in a select group of Sub-Saharan nations which have at some time been democratic between 1990 and 2010.

Diboration of Aldehydes: Formation and Synthetic Utility Peter Cannamela, Randall Clendenan Faculty Advisor: Timothy Clark Department of Chemistry and Biochemistry
The (ICy)CuOt-Bu complex, originally developed by Sadighi, has been shown to be an effective catalyst for diboration reactions of carbonyls. Diboration of such substrates allows direct access to a number of valuable products, α-trifluoroborate salts and β-hydroxyboronate esters have been the two main types of products this research has focused on. Trifluoroborate salts are extremely stable compounds and are efficient substrates in coupling reactions. Meanwhile, formation of β-hydroxyboronate esters represents the synthesis of a new C-C bond while retaining the C-B bond which remains available for further reactions. In both of these product types stereoselectivity can be controlled, meaning we are able to obtain a single diastereomer of our product, essential to the medical or industrial value of our synthetic products. Future work will focus on broadening the scope of trifluoroborate salt reactions and isolation of homologated products since purification has proved difficult in the past.

of Football Matches in England and the Effects of the Recent Economic Recession Roy Bourgazas Faculty Advisor: Andrew Narwold School of Business Administration, Economics
After the separation from The Football League and the formation of the Premier League, the demographics of football (soccer) fans in England have greatly shifted. Ticket prices have gone up on account of the rise in popularity of the Premier League with fans tuning in every weekend from all around the world. Many of the working class cannot attend the matches of the teams they support as they are priced out of attending. This has caused a drop in attendance from some clubs in lower positions in the league. This study will develop a linear regression model to analyze what affects stadium attendance, taking into account variables such as the prestige of the club and how well the club is performing in the league. Another variable included will measure the effect of the recent economic crises on the attendance of football fans. 24 U n d e r g r a d u at e R e s e a r ch C o n f e r e n c e
