The effect of weathering on the forensic comparison of disposable gloves

Rimkus, Claire Lillian January 2013 (has links)
Disposable gloves are often used by the perpetrators of a crime to prevent the deposition of fingerprints and epithelial cells at a crime scene. When removed and discarded at the scene, these items of evidence are often analyzed by a Trace Evidence Unit. By evaluating basic physical and chemical characteristics, a comparison to a known glove can be made. However, it is unclear whether temperature and weather conditions at a crime scene can alter the characteristics of the glove, and have a detrimental effect on this evidence comparison. In this study, a variety of disposable gloves made of nitrile rubber, natural rubber latex, and polyvinyl chloride were studied to assess the relationship between environmental conditions and polymer characteristics. Samples were placed in evidence envelopes or immersed in distilled water at three different temperatures, and were analyzed after 0, 3, and 6 weeks. Analysis included thickness measurements, stereomicroscopy, and Fourier-Transform Infrared Spectroscopy (FTIR). Results demonstrate that disposable gloves are susceptible to physical changes when exposed to various conditions. A majority of gloves exhibited an increase in thickness measurements at a variety of temperature and moisture conditions. Several gloves — spanning all types and different brands — displayed subtle changes in surface texture and spectral data. Analysis was complicated by the fact that no glove is 100% polymer, but instead contains a variety of additives, including stabilizers, plasticizers, and dyes. Additional characterization with a quantifiable separatory method, such as Pyrolysis-Gas Chromatography/Mass Spectrometry, is therefore recommended to further elucidate the changes that can occur.

Regional Income Disparities in Canada

Mcphee, Donald 04 1900 (has links)
<p> An important problem existing in Canada today is that of unequal regional economic development. It is a basic problem of some regions having more and other regions having less. </p> <p> In a country where economic growth is quite often viewed as an accumulation of regional economies, it is important to identify the inequalities that exist between and within these regions. Of the numerous forms of economic disparities, income is generally considered the most prevalent. </p> <p> The majority of research performed on this topic of regional income disparities tends to deal with either regional productivity levels or regional income distribution and redistribution. </p> <p> This study however, is concerned with disposable income levels that exist throughout and within Canada's regions, in an attempt to determine that the quality of life is not equitable across these regional boarders. The main observations of the study were that, definite disparities exist not only between Canada's regions but, within them as well. Also, that metropolitan areas of the country experience a better quality of life, based on calculated welfare statistics, than do non-metropolitan areas. Finally, it was evident that Canada's economic disparities in most recent years have remained relatively constant. </p> / Thesis / Bachelor of Arts (BA)

The impact of e-tolling on the recreational spending of people living in the Vaal Region / Laurent Pacariz

Pacariz, Laurent January 2014 (has links)
The primary objective was to ascertain whether implementation of the e-tolling system will influence the spending on recreational activities by people staying in the Vaal Region. Thus the aim was to assess whether an incremental rise in expenses, leading to a decrease in available disposable income will impact people’s decisions to travel outside their residences to visit and engage in leisure destinations and activities respectively. A questionnaire was developed and distributed with the primary objective of determining whether people within the Vaal Region are aware of the costs associated with travelling using the e-toll Gauteng freeways, and whether it will have an impact on their decisions to travel from their respective residences to leisure properties elsewhere. It also probed the respondents for the type of leisure activities they engage in, frequency of visits and the reasons for participating in the respective activities. The study shows that the e-toll project will inevitably, from a monetary perspective, affect all road users travelling from the Vaal Region to the greater Johannesburg areas. This is significant and confirms that the e-toll project will be perceived to have an impact on people’s available and disposable income. With the implementation of the e-tolling project seemingly imminent, businesses and consumers will feel the belt tighten in the leisure and recreational (and in particular the casino) industry, which is dependent on the availability of disposable income, to be ultimately affected. Trends with regards to leisure activities were identified along with recommendations for future research. / MBA, North-West University, Potchefstroom Campus, 2014
