Synthesis and Characterization of Au:Ag Core-Shell Nanoparticles with 4-Aminothiophenol Surface Enhance Raman Spectroscopy (SERS) Tag

At the Linfield Symposium the research on silver coated gold nanoparticles tagged SERS will be presented. Gold core nanoparticles were synthesized and coated with a silver shell. These core-shell nanoparticles were tagged with a Surface Enhanced Raman Signal (SERS) tag, 4-aminothiophenol. These tagged particles were monitored for stability and signal enhancement over time. When stability was proven, the tagged particles were coated with a polymer (PAH) and then a lipid bilayer (POPS:LPC). These particles were again monitored for stability and signal strength on the Raman. The overall goal was to synthesize silver coated gold nanoparticles, tag and enhance their Raman signal, and coat them with lipids while keeping the particles at a reasonable small size

Is Soil Quality Linked to PSNP Graduation in East and West Hararghe, Ethiopia?

Many households in Ethiopia have struggled to remain food secure and meet their nutritional needs. In response to chronic food insecurity the Ethiopian government developed the Productive Safety Net Program (PSNP) to provide support to households in the form of food or cash transfers in exchange for public service work. The idea of the program is that households will develop their livelihoods through the public work and eventually become self-sufficient, food secure and graduate from the PSNP. Some households graduate from PSNP in a shorter time than others, attributing to many different factors. This study looks at soil quality as a factor influencing a household’s ability to graduate and hypothesizes that houses which have already graduated from PSNP will have soil of better quality. The survey was conducted with the University of Maryland’s Qualitative Soil Assessment Book indicator table for PSNP graduate, PSNP participant and non-PSNP households. Results of the survey proved that PSNP graduate households had soil of better quality. The follow paper also discusses the need for further research as well as implications for sustainable development. PSNP, food insecurity, soil quality, Ethiopi

Scoping study of potential health effects of fortnightly residual waste collection and related changes to domestic waste systems

This report presents a review of international research into waste collections commissioned by WRAP and the Chartered Institution of Wastes Management (CIWM). The report’s findings have confirmed existing advice for councils and householders on avoiding risks to public health. No evidence was found that changing to a fortnightly collection creates risks that cannot be dealt with by following the good practice guidance already available

Structure on Attitude Polarization

People hold attitudes about a wide range of issues. People hold attitudes about issues ranging from toothpaste brands to foreign policies. One issue, for example, that has recently become salient in both the United States and Europe is illegal immigration. Consider two people sitting around discussing current affairs. One person mentions illegal immigration. The other person states that immigration is becoming a problem, but there are other things the government should worry about first. After a few minutes of thought, the gentleman that stated the government should worry about other things first blurts out that illegal immigration will be the downfall of this country! How could this person’s attitudes become so extreme in such a short period of time? When people are given an opportunity to think about an attitude object (e.g., persons, places, issues), their attitudes toward that attitude object tend to polarize (Tesser, 1978; Tesser, Martin & Mendolia, 1995). That is, attitudes that are initially favorable tend to become more favorable, whereas initially unfavorable attitudes tend to become more unfavorable. This phenomenon is referred to as self generated attitude change. Sadler and Tesser (1973) first researched this process of self generated attitude change by playing participants a recording of either a “likeable partner” that complimented these participants or a “dislikable partner” that criticized these participants. Participants were then asked to either think about their partner or were distracted from thinking about their partner. When given an opportunity to think about their partner, participants in a “likeable partner” condition held more favorable attitudes about their partner than did those participants in a distraction condition. Similarly, when given an opportunity to think about their partner, participants in a “dislikeable partner” condition held more unfavorable attitudes about their partner than did those participants in a distraction condition
