Thesis (M.Sc. (Geography)) -- University of Limpopo, 2021 / Hazardous wastes (HW) refer to wastes that may or tend to cause adverse health effects on the ecosystem and human beings. These wastes pose present or potential risks to human health or living organisms, due to the fact that they are: (i) non-degradable or persistent in nature, (ii) can be biologically magnified, (iii) are highly toxic and even lethal at very low concentrations. Various types of production activities in South Africa generate many by-products, which are usually discarded but often turn out to be sources of acute environmental hazards. If not contained and handled appropriately, waste, including HW can cause significant problems. Unattended HW lying around leads to unhygienic conditions resulting in health problems. Increasing population growth, accompanied by rapid urbanization and industrialization, increases the volume of HW generated in the country. Improper waste management is aesthetically unattractive and impacts negatively on tourism by creating blight on South Africa’s beautiful landscape. The aim of the study is to assess how HW is discarded across different land use zones in the Musina Local Municipality in order to reduce and manage the negative impacts that they exert to the environment and human health. The objective was to: (i) analyse the state and management of hazardous waste discarded by beauty salons of the central business district of Musina; (ii) Elucidate the state and management of hazardous waste discarded by households located in the suburbs of Musina; (iii) Document the state and management of hazardous waste discarded by automotive workshop located in the Industrial zone of Musina and (iv) Develop tailor-made recommendations for the safe management of hazardous waste in the town of Musina, Limpopo Province, South Africa The study was conducted in Musina Local Municipality in Limpopo province, South Africa. Musina is the northern town in the Limpopo Province of South Africa. The study sites were divided into three land use zones; central business district (CBD), suburban area, and industrial zone. In terms of methodology observations, a datasheet and a semi-structured questionnaire were used to collect data on HW management across three different land use zones. A total of 73 semi-structured questionnaires (55 in suburban area and 10 in industrial zone and 8 in the Central Business District) were employed to document quantitative and qualitative data. Observations were used to identify the types and document quantity of HW discarded by all participants. The researcher opened the weekly municipal refuse bags that stored discarded products to list and count HW products. The information was captured on a datasheet, which recorded data on type, quantity and separation of hazardous waste from general waste. Data was analysed via descriptive statistics. Results from Central Business District (Salons) shows that nail varnish bottles were the most discarded HW product with 250 discarded per week by all eight salons. Other HW products discarded include artificial nails, hair dye containers, plastic combs, vinyl gloves and disinfectant containers. All salons practice the same disposal method; making use of municipal refuse bags for temporary storage, which is then transported to the municipal landfill site for final disposal. None of the participants separate waste; reasons being lack of awareness of separation management. Shop owners and employees’ attitude towards HW management was neutral while their level of knowledge on the environmental and human health impact was rated low. Seventy-five percent of the respondents were not aware that the products they discard are hazardous. Results from Suburban area (household hazardous waste) shows that home cleaning products were the most discarded Household Hazardous Waste (HHW) product with 237 discarded per week by all 55 sampled households. Other HHW products discarded include personal cleaning products, miscellaneous items, automotive maintenance and gardening products. The 50 households practice the same disposal method; making use of house bin (usually pedal bins). Once the bin is full, they dispose it to the outdoors wheelie bins. The remaining five household dispose of their waste directly to the outdoor bin. None of the participants separated waste; main reasons being lack of awareness of separation management. Participants’ attitude towards HW management was neutral while their level of knowledge on the environmental and human health impact was rated medium. Seventy-three percent of the respondents were aware that the products they discard are hazardous. Results from Industrial Zone (hazardous waste) shows that plastic components were the most discarded hazardous waste (HW) product with 31 discarded per week by all 10 sampled automotive workshops. Other HW products discarded include lead-acid batteries, automotive used oil and paint containers. Automotive workshops practice different storage and disposal method; making use of drums, large containers and old scrap car as a temporary storage place. Once the temporary storage is full, 50% opted for recycling while 30% dispose of their waste to the landfill site; the remaining 20% burn their waste in their premises. A large majority (80%) did not separate their waste; main reasons being a lack of awareness of separation management. Participants’ attitude towards HW management was positive while their level of knowledge on the environmental and human health impact was rated low. Half of the respondents were aware that the products they discard are hazardous. Many studies have looked at the comparison between wastes discarded in the rural versus urban area with little attention on specific enterprises. It is more realistic to consider other enterprises because different activities generated different waste. This study was able to assess how waste is discarded in different enterprises such as salons and automotive workshop with an addition of residential waste. To the best of our knowledge this is the first study of this kind. Future research can look at other enterprises such as HW from restaurant or as far as HW discarded by mining sector. The study recommends that the salon enterprise obtains a HW certificate prior to operating a salon, this will increase awareness and make employees more knowledgeable on issues relating to the management of HW. Most of the wastes discarded by sub-urban area were recyclable materials. The municipality can look into collecting recyclable materials separately and taking it to the recycling facilities. It was shocking to find out that there are automotive industries that burn their waste (without even separating). This poses a serious danger in terms of air pollution and the possibilities of containers exploding; therefore, there is an urgent need to educate people in the automotive industry.

Transit-Oriented Development (TOD) in downtown areas is a distinct form of new development, creating walkable districts and 24-hour neighborhoods. A new streetcar on Loyola Avenue in the New Orleans Central Business District was planned to encourage new development in the area. By analyzing the current land uses and values, projections of future change predict over $500 million in added value. For this development to become a successful TOD, policies must encourage uses that generate ridership and increase walkability. Although the Loyola corridor has many historic attributes of a transit-oriented downtown, it currently lacks neighborhood identity. The new development associated with the Loyola streetcar has the potential to become a downtown TOD.

As economias de aglomeração apresentam externalidades que impactam sobre os vetores de preços da economia. As interações que ocorrem nas aglomerações são relevantes para a compreensão dos benefícios gerados pela proximidade. Tais benefícios impactam diretamente o salário do trabalho e os preços dos imóveis, entre outros. Muitos trabalhos focaram em estudar economias de aglomeração no contexto espacial agregado, mas poucos estiveram focados no espaço intra-urbano. Em face dessa lacuna na literatura de Economia de Aglomeração, a análise nesta tese debruça-se sobre a Região Metropolitana de São Paulo (RMSP), que foi dividida em áreas homogêneas de 1 km2. Dois são os objetivos centrais desse trabalho. Primeiro, buscou-se identificar as áreas mais relevantes quanto à aglomeração de trabalhadores na RMSP, ou seja, os subcentros de emprego (SBD). Para tanto, utilizaram-se os microdados geocodificados do Ministério do Trabalho (RAIS- MTE) para os anos de 2002, 2008 e 2014. Uma nova abordagem empírica foi desenvolvida, utilizando Regressões Ponderadas Geograficamente e uma regra objetiva de valor de corte. Os resultados apontam para três SBD nos anos de 2002 e 2008. No ano de 2014, a abordagem metodológica desenvolvida nessa tese com valor de corte mais restrito identifica apenas dois SBD. Nos dois períodos iniciais, os SBD se localizam em Barueri, São Paulo e São Caetano do Sul. No último ano avalidado, localizam-se em Barueri e São Paulo. O padrão observado é que o emprego localizado nas áreas centrais de São Paulo apresenta nível de crescimento relativamente maior do que nas demais áreas. Os demais SBD perdem não apenas em termos de emprego, mas também em termos de área, isto é, as áreas dos SBD nesses municípios se reduzem. Em 2002, os SBD de Barueri e São Caetano do Sul ocupavam áreas de 5 e 7 km2, respectivamente. Em 2014, o primeiro ocupava 1 km2 e o segundo deixou de existir. Em São Paulo, a área se elevou de 79 km2 para 90 km2. Os resultados sugerem elevada concentração espacial do emprego na RMSP. No segundo ensaio, objetiva-se identificar o impacto da aglomeração sobre os salários dos trabalhadores e, adicionalmente, testa-se a hipótese de atenuação espacial da aglomeração. Para tanto, construiu-se uma base de dados longitudinal e considerou-se uma especificação com múltiplos efeitos fixos e defasagem espacial da aglomeração de emprego. Mesmo em face de uma especificação mais restritiva, os resultados sugerem efeito positivo da aglomeração, o qual é atenuado com o distanciamento espacial. Em outras palavras, a aglomeração impacta positivamente o salário. Em estimações que desconsideram a questão da endogeneidade, estima-se um efeito direto (na própria área) de 0,039%, efeito indireto de primeira ordem (em áreas contíguas) de -0,11% e efeito indireto de segunda ordem (anel externo às áreas contíguas) de -0,23%, normalizado por 100,000. Ao tratar o problema da endogeneidade, através do uso de variáveis instrumentais, obtém-se efeito direto de 1,78%, indireto de primeira ordem de -2,12% e o efeito de segunda ordem não é estatisticamente significante. / Agglomeration economies are externalities that impact on prices in the economy. The interactions that occur in agglomerations are relevant for the understanding of the benefits generated by proximity. These benefits directly affect workers\' wage, real estate prices, etc. Many papers have focused on non-market interaction in aggregated labor markets, but intra-urban labor markets have received less attention. Seeking to fulfill such lack, 1 km2 areas of the Metropolitan Area of São Paulo (MASP) are taken as the scope of analysis of this study. The central objectives of this dissertation are twofold. First, in chapter 3, I identified and characterized the most relevant areas in terms of job agglomeration in the MASP, named subcentral business districts (SBD). For this purpose, the geocoded matched employer-employee database of the Ministry of Labor (RAIS- TEM) was used. I developed a new empirical approach to identify the SBD, using Geographicaly Weight Regression and cut-off rules of identification. The results identified three SBD in the years of 2002 and 2008, and only two in 2014. Considering the two initial periods, the SBD are located in the municipalities of Barueri (SBD-BAR), São Paulo (SBD-SAO) and São Caetano do Sul (SBD-SCS). In the last year, the SBD are located in Barueri and São Paulo municipality only. The employment located in the central areas of São Paulo shows a relatively higher amount of employee than in the other SBD areas. SBD-BAR and SBD-SCS lost not only in terms of employment, but also in terms of area. In 2002, these last two SBD occupied areas of 5 and 7 km2 respectively. In 2014, the SBD-BAR occupied 1 km2, while the SBD-SCS is not ranked at all. In São Paulo, the area ranges from 79 km2 to 90 km2. The results stemmed from the first paper suggest a high spatial concentration of employment in the MASP. In the second paper (chapter 4), the objectives are to identify the impact of agglomeration on workers\' wages and test the agglomeration spatial attenuation hypothesis (SAH). For that, I use employer-employee RAIS database and consider a specification with multiple fixed effects and spatial lags of the employment agglomeration as a strategy to SAH identification. Even in the face of a more restrictive specification, the results suggest a positive effect of agglomeration, which is attenuated as the spatial distance increases. In other words, agglomeration affects positively workers\' wage in the workplace area. Estimates without solving for endogeneity between wage and agglomeration indicate a direct effect of 0.039% (in the area itself), a first-order indirect effect of -0.11% (in the contiguous areas), and a second-order effect of -0.23% (in the ring around the contiguous areas), normalized by 100,000. When considering instrumental variables, the estimated direct effect on wages becomes 1.78%, the first-order effect changes to -2.12%, and the second order effect is not statistically significant.

The questions arising over the deterioration of the 0BD have brought this topic to the attention of the public. This thesis will discuss the Central Business District of D311a5 and its decline. In order to study alternatives to these downward trends, the Central Business District Association of Dallas commissioned Alexander Cooper to make. an analysis of the possibilities for one alternative, namely, housing. The purpose of this study is to examine the le.rander Cooper Report on housing. The facts presented in this thesis will provide an analytical base of urban theory from which a discussion of housing prospects will be initiated. The feasibility of dointovm housing construction will 'be examined as it is presented in the Cooper Report.

Historic preservation has been a successful economic development tool that has led to heritage tourism in some Tennessee towns but not in others. The problem studied was to determine if there was a set of tangible attributes a town must possess to be successful in using historic preservation as an economic development tool. Through an extensive literature review, 59 predictor variables were identified and arranged into 6 research questions looking at the tangible attributes related to town demographics, geography, organizational structure, historic preservation organizations, heritage tourism organizations, and town financial structure. Data were collected from a mailed survey of 32 town managers. The response rate was 68.8% (N = 22). Secondary sources, such as U.S. Census data, were used to collect data when those sources appeared consistent and mandatory. The study used logistic regression analysis to compare successful towns, defined as those towns in the upper third of study towns for tourism expenditures per capita, with less than successful towns. The 32 study towns met the criteria of having a 2003 population of fewer than 10,000 and a nationally-recognized historic district that coincided with the towns' central business districts. The results of the logistic regression analysis on the individual predictor variables indicated that 5 were statistically significant--median age, distance to a major city, restaurant beer sales, Grand Division, and merchants' association. Constraining the final predictive model (Garson, 2006) to no more than 1 variable per 10 cases 3 led to the inclusion of median age and merchants' association as the 2 predictor variables that provided the highest predictive value of correctly classified towns (95.8%). In summary, this study is inconclusive in determining whether historic preservation leads to heritage tourism and can be used as an economic development tool by small Tennessee towns. However, it has been established that 5 attributes or characteristics of small towns does contribute to the probability of success and that median age and the existence of a merchants' association proved to be the best predictive model.

M. Tech. Architecture (Professional) / This dissertation responds to the current urban situation in Pretoria's Central Business District and entails the design of a Creative Hub through the rejuvenation of Pretoria's Burlington Arcade in the Church Square node. The Creative Hub will function as an incubator space for the creative industry, as well as potentially becoming a catalyst for the rejuvenation of the inner-city of Pretoria. Tshwane's inner-city's economic role has reduced dramatically compared to cities such as Johannesburg. Private and public sectors turn their investment interest away from the city towards the suburbs. A solution needs to be found to encourage investment and increase visitor confidence in the city's long term commitment to change. As with any urban regeneration project, it would require dedicated investment from the all sectors, over a lengthy period of time to initiate this change. The Creative Hub acknowledges urban renewal as the long term goal for the inner-city, but aims to evoke interest within the Church Square node to serve as a vehicle for change to occur through the introduction of "a people's place". Students, creative individuals and professionals, tourists, city dwellers, city goers as well as artisan traders are invited to meet within the space to promote Church Square as the historically rich, culturally textured environment it is.

Thesis (MTech. degree in Architecture (Professional))--Tshwane University of Technology, 2011. / Probably one of the strongest common threads running through the multi-cultural society of South Africa is its passion and love for the public performing arts. The thesis therefore encompasses the design of a Performing Arts Centre in Pretoria. The intention is to use the building and surrounding urban space to promote performing arts activities, where they can be taught, refined and performed. The intent is to provide a building which will not only house the performing arts, but also engage the urban place as a public performance stage.
