The inadequate food safety knowledge by street food vendors have been a challenge encountered in ensuring safety of street foods. The aim of this study was to assess the food safety knowledge of street food vendors in the Johannesburg metropolis and to evaluate the conformance and monitoring of their street food vending facilities in accordance to regulations governing general hygiene requirements for food premises in South Africa. A cross sectional survey was conducted in which 315 street food vendors and 155 street food vending facilities were observed using a questionnaire instrument and observational checklist, respectively. The majority (61.3%) of the street food vendors were females and most (64.1%) of them had not attended a food safety training course. Only a few (12.1%) street food vendors knew the correct minimum internal cooking temperature for stuffed chicken, while less than half knew the correct temperature for cold and hot holding of ready-to-eat foods, 40% and 39% respectively. The majority of them have never heard of Salmonella (92.7%), Campylobacter (95.2%), Listeria (57.1%), Clostridium (94.3%), or Staphylococcus (87.6%). Up to 52% street food vendors had moderate food safety knowledge. Most of the street food vending facilities (68.3%) had been inspected by health inspectors and only 17% of street food vending facilities had low level of compliance to regulations governing general hygiene requirements for food premises and the transport of food in South Africa. The overall food safety knowledge of street food vendors in Johannesburg metropolis was moderate. The level of compliance and monitoring of street food vending facilities to regulations governing general hygiene requirements for food premises in South Africa was satisfactory. Street food vendors should be trained on internal cooking temperature, hot and cold storage temperature of ready-to-eat foods, and food pathogens such as Salmonella, Campylobacter, Listeria, Clostridium, and Staphylococcus / Life and Consumer Sciences / M.

Denna kvalitativa studie undersökte handlingsutrymme hos socialarbetare inom socialtjänsten enligt Lipskys (2010) teori om gräsrotsbyråkrater inom en kommun som inte arbetar utefter bostad först-modellen för att motverka hemlöshet. Fyra handläggare som regelbundet hanterar ärenden där klienter är eller riskerar att bli hemlösa intervjuades, två som arbetar inom biståndsenheten och två som arbetar inom utredningsenheten boende. Inhämtad empiri tyder på ett märkbart handlingsutrymme hos respondenterna, och författarna av denna studie tolkar standardisering som en av de mer begränsande faktorerna i detta handlingsutrymme. Vidare tolkar studiens författare resultaten från intervjuerna att en begränsning av tillgängliga insatser handläggarna kan erbjuda klienter påverkar deras upplevda handlingsutrymme. / This qualitative study aimed to research discretion among social workers in the social services according to Lipsky’s (2010) theory of street-level bureaucracy within a municipality which does not utilize housing first as a solution against homelessness. Four case workers who regularly administrate cases involving homelessness or risk of homelessness among clients were interviewed, two working in the assistance unit (biståndsenheten) and two working in the housing investigation unit (utredningsenheten boende). Findings indicate noticeable levels of discretion among the interviewees, and the authors of this study interpret standardization as one of the more limiting factors in their discretion. In addition, the study’s authors interpret results from the interviews as an indicator that the amount of interventions the case workers can provide their clients limits their discretion.

This thesis is an intimate exploration. A personal journey between here and there: what I left behind, what I always kept close to me and all the new things that I learned and experience during the last four years. I just tried to put myself together as a person as well as an architect; taking from my personal experiences the inspiration and the tools to create a building. The building is orientated to American and foreign students coming to the metropolitan area of Washington DC to study at the Center and willing to take advantage of the opportunities of the city. The idea was to create a building for civic adaptation, to educate and inspire students not only in architecture but also in civic life and prepare them to be responsible citizens. The dormitory was inspired by the friendly spirit of the WAAC with the intention of supporting the Center in its varied goals and enhancing its academic perspectives. / Master of Architecture

Many municipalities around Sweden use public access spatial data from Artportalen to track and fight invasive species, but anyone can upload data to Artportalen and not all of it becomes verified. They could potentially enhance their efforts by incorporating street view technology for more reliable data. One municipality that uses Artportalen data is Jönköping, which suffers from Reynoutria japonica. I randomly selected 50 areas around Jönköping with reports of R. japonica and went through them using Street View. The purpose of this study is to test if Street View can be used to improve the reliability of Artportalen data and if it can fully replace other methods to do so. I counted each individual of R. japonica I could identify and compared it to the number of reports in each area. Among the 50 areas only 26 were reachable in Google Street View and some plants were impossible to identify if they were R. japonica or not. When looking at the areas that could be reached it showed no difference between Reports in Artportalen and what was found in Street View if you included the unidentifiable plants. When excluding unidentified plants or when including areas that could not be reached it showed a significant difference. Using Google Street View to complement Artportalen data for R. japonica comes with benefits and limitations. Many areas were impossible to reach, but where accessible, it proved effective in identifying misreports and finding unreported plants without the need to visit the location. Street View data can enhance the reliability of distribution data used for monitoring invasive species without ever needing to travel, however it cannot fully replace other methods of enhancement and for the best reliability, a combination of Street View and on-site visits is necessary. / Många kommuner runt om i Sverige använder offentligt tillgängliga geodata från Artportalen för att spåra och bekämpa invasiva arter, men vem som helst kan ladda upp data till Artportalen och inte all data blir verifierad. Kommunerna skulle potentiellt kunna förbättra sina insatser genom att använda Street View teknologi för att få mer tillförlitliga data. En kommun som använder sig av data från Artportalen är Jönköping, som lider av den invasiva växten Reynoutria japonica. Syftet med den här rapporten är att testa om Street View kan användas för att komplimentera data från Artportalen och om det kan helt byta ut andra metoder att göra samma sak. Jag valde slumpmässigt ut 50 områden runt Jönköping med rapporter om R. japonica och gick igenom dem med Street View. Jag räknade varje individ av R. japonica jag kunde identifiera och jämförde det med antalet rapporter i varje område. Bland de 50 områdena var det bara 26 som kunde nås med Google Street View och vissa växter var omöjliga att identifiera om de var R. japonica eller inte. När man tittade på de områden som kunde nås visade det ingen skillnad i antal växter mellan rapporterna i Artportalen och vad som hittades i Street View om man inkluderade de oidentifierbara växterna. När man exkluderade oidentifierade växter eller när man inkluderade områden som inte kunde nås visade det en signifikant skillnad. Att använda Google Street View för att komplettera Artportalen-data för R. japonica har både fördelar och begränsningar. Många områden var omöjliga att nå, men där de var 2 tillgängliga visade det sig effektivt för att identifiera felrapporter och hitta orapporterade växter utan att behöva besöka platsen. Street View-data kan förbättra tillförlitligheten av distributionsdata som används för att övervaka invasiva arter utan att man någonsin behöver resa, men det kan inte fullt byta ut andra metoder att öka tillförlighet och för bästa resultat är en kombination av Street View och platsbesök nödvändig.

With time going by, urban morphological structures of Beijing and Shanghai have dramatic changes during last decades. These changes often ignored by citizen, but have big influence for human daily life. And the changes of urban morphologies should be easily recognized by citizen. There are many previous comparative studies between these two Chinese cities, and these studies focus on types of areas, such as environment, traffic, city planning and cultures etc.. There are also many comparative studies about using space syntax theory and geometrical statistics to study urban morphologies. However, there are not direct comparison urban morphological study between Beijing and Shanghai, which from multiple perspectives. In order to gain a better understanding of urban morphologies, this thesis take street networks of two Chinese cites as a research object, based on space syntax theory, as well the combination of traditional geometrical statistics, comparative analysis methods to systematic quantitative analyze and comparative study the different street networks of urban space in Beijing and Shanghai. This project work analyzes hierarchy of axial lines, which automatically generated from street networks, to do a morphological comparison from topological perspective. And it analyzes frequency distribution of axial lines’ included angles and length of axial lines to study urban morphologies from geometrical perspective. Results in the project seem to empirical study that, the well-connected streets are minority part, which all most distributed in the sample cities’ ring structures and center areas. Street networks constitute an obvious regular grid pattern of Beijing and a curves pattern of Shanghai. Based on the hierarchical levels of street networks, research samples have same hierarchical levels but without the same number of street lines. The included angles of axial lines have an exceptionally sharply peaked bimodal distribution for both cities and number of most connected street’s length do not increase so much from ring1 to ring6 for Beijing, but they have much change for Shanghai.

Recently, there has been an increasing interest in looking at urban environment as a complex system. More and more researchers are paying attention to the study of the configuration of urban space as well as human social activities within it. It has been found that correlation exists between the morphological properties of urban street network and observed human social movement patterns. This correlation implies that the influence of urban configurations on human social movements is no longer only revealed from the sense of metric distance, but also revealed from topological and geometrical perspectives. Metric distances, topological relationships and angular changes between streets should be considered when applying space syntax analysis to an urban street network. This thesis is mainly focused on the comparison among metric, topological and angular analyses based on three kinds of urban street representation models: natural streets, axial lines and axial segments. Four study areas (London, Paris, Manhattan and San Francisco) were picked up for empirical study. In the study, space syntax measures were calculated for different combinations of analytical methods and street models. These theoretical space syntax accessibility measures (connectivity, integration and choice) were correlated to the corresponding practical human movement to evaluate the correlations. Then the correlation results were compared in terms of analytical methods and street representation models respectively. In the end, the comparison of results show that (1) natural-street based model is the optimal street model for carrying out space syntax analysis followed by axial lines and axial segments; (2) angular analysis and topological analysis are more advanced than metric analysis; and (3) connectivity, integration and local integration (two-step) are more suitable for predicting human movements in space syntax. Furthermore, it can be hypothesized that topological analysis method with natural-street based model is the best combination for the prediction of human movements in space syntax, for the integration of topological and geometrical thinking.

Master of Landscape Architecture / Landscape Architecture/Regional and Community Planning / Brent Chamberlain / Streets and sidewalks are important public places for a wide variety of activities, such as social interaction and physical activities. Public spaces can provide numerous benefits, such as physical, psychological, social, spiritual, and aesthetic wellbeing; in order to maximize these benefits effective planning and design is critical. However, there is a need to increase empirical data which can support good planning for these public spaces. The purpose of this research study is to better understand how different elements of streetscape design influence a person’s preferences for the design of the space. A streetscape consists of a variety of different infrastructure and natural forms, which are combined together to create a space centered on the movement of people. A survey was conducted with the aims to better understand how key design elements may influence users’ preferences with regard to safety and attractiveness. The project study site is Moro Street in Aggieville Business District in Manhattan, KS. The study and survey were developed using the psychophysical approach, which employed a quantitative methods to analyze the perceptions of Aggieville patrons. The research methods consists of four main parts: variable selection, streetscape design, public survey, and data analysis. An ANOVA was conducted that revealed statistically significant effects related to the preference for streetscape design in terms of safety and attractiveness, as well as a combined average evaluation. Evidence shows that the on street parking (Parking) and green infrastructure (Green Infrastructure) are statistically significant (p < .05), whereas seating and biking had no statistically significant effect on the evaluation of attractiveness. Also, the on street parking (Parking), green infrastructure (Green Infrastructure) and bike lane (biking)are statistically significant (p < .05), whereas seating had no statistically significant effect on the evaluation of safety. Overall, on street parking (Parking) and green infrastructure (Green Infrastructure) are statistically significant (p < .05), whereas seating and biking had no statistically significant effect on the evaluation of both safety and attractiveness. These results support previous work from environmental psychologists, and provide additional empirical evidence to support effective street design.

The purpose of this thesis is to analyze changes over time in the interactions of street-involved youth with their risk environments and to investigate how their integration into local, provincial, and federal systems and services impacts their lives, health, and substance use. This thesis employs a sequential explanatory mixed methods design and uses closed and open-ended questions collected over five waves of interviews during the longitudinal study Risky Business? Experiences of Street-Involved Youth. Quantitative (n = 50) methods of analysis include descriptive statistics and bivariate comparisons complemented by a qualitative (n = 15) thematic analysis comprised of open-ended interview questions. The risk environment framework proposed by Tim Rhodes is used to highlight structural and systemic forces informing the lives of street-involved youth, allowing for an analysis on three levels of influence (micro, meso, macro) and four types of environment (economic, physical, social, policy). Results indicate that comparatively high substance use and harms of substance use among street-involved youth decrease as they become integrated into local, provincial, and federal systems and services. Intersecting demographic and structural factors correspond with higher substance use for male youth and youth who had been involved with the foster care system during their life. Given the diversity of backgrounds and risk environment experiences, street-involved youth expressed diverse opinions and perspectives regarding the effectiveness of healthcare, harm reduction, and outreach services. Policy recommendations and suggestions for future research are suggested, with the aim of developing safer environments and environment interventions for street-involved youth that reduce substance use-related harms. / Graduate
