Shopping leakage facing Maseru town.

Osuigwe, Chukwuemeka Ezenwa. January 2005 (has links)
This dissertation is an attempt to understand shopping leakage from Maseru to Bloemfontein and Ladybrand. It investigates the patterns of shopping leakage and factors that contribute to the leakage. Theories were understood to prove the on going shopping leakage from Maseru. The rentral plare theory was explored to show how a hierarchy of plares influenres retail and shopping activities. Other location theories such as theory of tertiary activities was utilised to explore the impact of income, types of employment and buying power on retail location and shopping activities. Rationality theory was employed to verify the rational in the shopping movement from Maseru to Bloemfontein and Ladybrand. The study was based on focus groups, interviews and observation. The patterns of shopping from Maseru to Bloemfontein and Ladybrand are mainly for higher order goods and specialised goods such as quality clothes, shoes, jewelleries, and furniture. However some people who have cars buy groreries from Ladybrand that is closer to Maseru than Bloemfontein. The shopping trips were multi purpose activities. A shopper combines shopping with two or more activities such as banking recreation, hospital checkups, salon and tourism. Maseru does not have enough thresholds for some high order goods and services, and this leads to the shopping leakage. Although the employment rate in Maseru is high, income is generally lower. Shopping leakage was trared to rertain aspects of consumer behaviour, the characteristics of the shopping trip, retail facilities and types of shops available. Socio-economic factors also influenre shopping pattern, as do entertainment activities. Government and corporate bodies such as banks, through their regulations and laws created an impact on the shopping leakage from Maseru to Ladybrand and Bloemfontein. It is assumed that topography and burning of retail buildings in Maseru in September 1998 also limits the retail facilities in the town. Finally, the growth of Maseru is slow and steady, therefore it can be implied that retail trading in Maseru is following the same sequenre as the growth of the town. / Thesis (M.T.R.P.)-University of KwaZulu-Natal, Durban, 2005.

Hispanic Migrants and Cross-border Disease Control of Arizona's Vaccine Preventable Diseases

Chocho, Karen 30 April 2008 (has links)
BACKGROUND: According to the Centers for Disease Control and Prevention and the National Immunization Program, there is an increase in the re-emergence of past diseases. Even with mandatory vaccination practices in the United States, there are still a number of cases of vaccine-preventable diseases (VPDs) reported yearly. It is speculated that the re-emergence of VPDs is in part due to the increase in international travel as well as the influx of immigrants. One particular group of interest includes the Hispanic migrants coming from Central and South America where some of these diseases are endemic. OBJECTIVE: The purpose of this paper is to determine the extent of VPD cases in the border state of Arizona that may be attributed to Hispanic migrant influx using data from the MMWR: Summary of Notifiable Diseases reports for the United States and the ADHS data from all Arizona counties. RESULTS: Since 1995, rates of hepatitis B and pertussis have been increasing in Arizona and have become higher for non-Hispanics than Hispanics. In 2005, hepatitis B rates were 1.53* for the United States and 7.31* for Arizona; pertussis rates were 8.72* for the United States and 21.60* for Arizona. CONCLUSION: The results of this study's analysis show the need to improve immunization efforts within the non-Hispanic populations in all Arizona counties. (*Per 100,000 population)

Essays on trade and environment

Sanctuary, Mark January 2013 (has links)
The thesis comprises four essays examining aspects of international trade and environment. "Border carbon adjustments (BCAs) and Strategic Climate Policy" examines how BCA affects government incentives to regulate emissions and trade in a strategic setting and contrasts the impact of a BCA and a tariff: the distinction being that the level of the BCA is a function of the difference in the trade partner's emission taxes whereas the tariff is not. I show that a BCA leverages the exporter's climate policy provided the exporter has little influence over world prices (i.e. export supply elasticity is large) and has a weak climate policy. "How does the price of electricity affect imports? A study of Swedish manufacturing firms" examines the heterogeneous effects of a domestic electricity price increase on the structure of imports. We identify the magnitude of the impact of the electricity price increase on the structure of firm imports. Our findings agree with the predictions of our theoretical model. "Trade, Transboundary Pollution and Market Size" suggests a new set of theoretical reasons that may help reconcile the contradictory empirical evidence of the impact of trade liberalization on the location of production to countries with weaker pollution policy. Our results suggest that relative market size, the level of trade costs, the ease of abatement, and the degree of product differentiation at the sector level are relevant variables for empirical studies on trade and pollution. Market shares for organic products are typically modest. Yet several consumer surveys find that a majority of respondents would buy substantially more of these products even if they cost more. "What’s holding it back? A study in organic retail coffee purchases" explores reasons for this apparent divergence. The results suggest that the limited overlap between organic and other highly-valued characteristics is one of the most important constraints.

Cost-Sensitive Classification Methods for the Detection of Smuggled Nuclear Material in Cargo Containers

Webster, Jennifer B 16 December 2013 (has links)
Classification problems arise in so many different parts of life – from sorting machine parts to diagnosing a disease. Humans make these classifications utilizing vast amounts of data, filtering observations for useful information, and then making a decision based on a subjective level of cost/risk of classifying objects incorrectly. This study investigates the translation of the human decision process into a mathematical problem in the context of a border security problem: How does one find special nuclear material being smuggled inside large cargo crates while balancing the cost of invasively searching suspect containers against the risk of al lowing radioactive material to escape detection? This may be phrased as a classification problem in which one classifies cargo containers into two categories – those containing a smuggled source and those containing only innocuous cargo. This task presents numerous challenges, e.g., the stochastic nature of radiation and the low signal-to-noise ratio caused by background radiation and cargo shielding. In the course of this work, we will break the analysis of this problem into three major sections – the development of an optimal decision rule, the choice of most useful measurements or features, and the sensitivity of developed algorithms to physical variations. This will include an examination of how accounting for the cost/risk of a decision affects the formulation of our classification problem. Ultimately, a support vector machine (SVM) framework with F -score feature selection will be developed to provide nearly optimal classification given a constraint on the reliability of detection provided by our algorithm. In particular, this can decrease the fraction of false positives by an order of magnitude over current methods. The proposed method also takes into account the relationship between measurements, whereas current methods deal with detectors independently of one another.

‘Working the Border’ Risk and Interagency Communication At an International Airport

Tolerton, Mason John January 2009 (has links)
This thesis seeks to answer the ‘key question’: ‘how is the border worked at an international airport?’ To answer this key question the author, who is employed as a Customs officer, uses participant observation to provide material for an anthropological analysis of this question. The primary anthropological focus that will permeate throughout this thesis is interconnectedness of human and non human actors. This focus on interconnectedness will be linked to the ability of the workers of the border to communicate about risk to one another. Risk at the border is highly political following the terrorist attacks of September 11 (9/11). The attacks are not a focus of this thesis but a study of the border network will shed some light on how the workers of the border make sense of external factors such as these attacks (9/11) in their work world. The thesis accounts for links between the border workers of different government agencies and uses the idea of an occupational community to do so. The thesis will attempt to account for technologies within the border network. The account of technologies will demonstrate through an actor network approach their hybrid nature, and their ability to negotiate and renegotiate the border network. Power is analysed at the border through the ideas of Foucault. Though the idea of occupational community, actor network theory and the ideas of Foucault on power are not linked outside of this thesis in any way, they provide an honest account of the border network as expressed through the case study of risk and interagency communication at an international airport.

Community involvement in the development of small hydro in Uttaranchal, India

McCandless, Matthew Michael 26 April 2007 (has links)
The purpose of this research was to determine the potential capacity for improved participation through community-based approaches to small hydroelectric development in the Indian Himalayas. The objectives of the research were: (1) to establish the current roles of the civic, public and private sectors in small hydro development; (2) to examine the potential for learning through participation during the development of small hydro projects; (3) to determine the potential for using community-based environmental assessment in future projects; (4) to investigate the benefits of community-driven small hydro development, and (5) to determine the implications of the findings for environmental policy and decision-making. Data were gathered using Participatory Rural Appraisal methods including semi-structured interviews, transect walks, and landscape analysis. There were five case study projects (Niti, Bampa, Jumma, Malari and Bamini/Badrinath), each in the Indo-Tibetan border region of the Indian Himalayas. The plants are all run of river, and range in capacity from 25 kW to 1.2 MW. Four of the villages had no electricity prior to the development of the small-hydro plants, while one had a prior connection to the state electrical grid (Bamini/Badrinath). The villages are inhabited by Bhotia tribespeople, and are occupied only during the summer growing season. The residents travel to lower altitude villages for the winter months. The most successful project examined, in the village of Malari, was one where community development and energy needs were considered simultaneously, and where the local community was highly involved in planning, construction and operation. The less successful projects were those where community involvement and development, sound planning, and detailed geographic information about the site were lacking in their development and operation; such as was observed in the village of Jumma, where the plant never began operations because it was damaged by an avalanche prior to its inauguration. PLEASE NOTE: As of January 2007 the State of Uttaranchal was renamed Uttarakhand. The change is not reflected in this thesis.

The Pig and the Postwar Dream: The San Juan Island Dispute, 1853-1872, in History and Memory

Lyall, Gordon Robert 30 April 2013 (has links)
Historical events are framed by the actors of the time and then re-framed by subsequent historians and the public. This thesis examines the historiography of the San Juan Island Dispute, 1853-1871, known colloquially in the twentieth century as the “Pig War.” In 1859, after an American settler on San Juan shot a pig owned by the Hudson’s Bay Company, the American military and the British Royal Navy met in a tense stand-off resulting in a twelve year joint-military occupation of the island. This conflict was the last border dispute between the two nations. Following World War II, a message of peace became the dominant trope of histories written about the “Pig War.” The term itself has come to represent this overarching theme. With documents from the dispute, such as colonial despatches, official correspondence and newspaper editorials, this thesis considers how the event was framed at the time; and employing semiotics as a technique for discourse analysis, it examines how the “war” was re-framed in the twentieth century. The thesis follows Alfred Young’s research on antebellum America’s commemoration of the “Boston Tea Party,” with its message appropriated by politicians, merging history and myth. The “Pig War” occupies similar terrain as the reconceptualization of the event embodies its own message of a unique identity for the Pacific Northwest, associated with the 49th parallel as the world’s longest, most peaceful, “undefended” border. / Graduate / 2015-04-26 / 0578 / 0334 / 0337 / lyallg@uvic.ca
