Thesis (MPhil)-- Stellenbosch University, 2001. / ENGLISH ABSTRACT: This ethical case study of public slaughter has indicated that there is an urgent need to address the issue of public slaughter, because it has resulted in animosity and polarisation between black and white people living in the Goldfields. Black people feel that their rights are violated, and they are not protected by the government because they encounter problems when practising their rituals. White people feel that the government is not protecting them from the health hazards caused by black people. The ultimate aim of the study is to contribute to and amplify the existing body of knowledge with regard to the extent of the problem experienced by people in the Goldfields, its impact in their every day lives and to propose guidelines that will help when regulations governing environmental issues are drawn. In order to accomplish these aims the following objectives should be realised by this study: • South Africa is a multi-racial country so a uniting policy is needed. • Each culture is unique and it has a special value, so no culture must be marginalised. • The old policy needs to be revised and amendments made. • Identify the actual causes of these problems. Are they racist driven or are they driven by genuine health concerns? This ethical study also indicates that the following are central values that should inform decision-making: • Health. • Respect and tolerance. • Communication. • Participation. Transparency. • Commitment. Based on the findings from the research conducted it is clear that both clashing parties (black and white people) need to live in peace at the ultimate end although their description of peaceful life differs, so the following recommendations are made as to how to address and alleviate problems caused by public slaughter. • A formal meeting must be convened to discuss this critical issue. • Drafted proposals must be produced. • The proposals must be debated. • The proposal must be adopted. • The existing bylaws must be changed. / AFRIKAANSE OPSOMMING: In hierdie gevallestudie in etiek oor slagtery in die openbaar is bevind dat daar 'n dringende behoefte bestaan om die probleem van slagtery in die openbaar aan te spreek, veralomdat dit in die verlede reeds tot spanning en polarisasie tussen swart en wit groepe in die Goudveld aanleiding gegee het. Swartmense voel dat hulle regte aangetas word en dat hulle nie genoegsaam deur die owerheid beskerm word om hulle rituele uit te voer nie. Witmense voel weer dat die owerheid hulle nie beskerm teen gesondheidsgevare wat geskep word deur swartmense nie. Die uiteindelike doel van hierdie ondersoek is om 'n bydrae te lewer tot die uitbouing van bestaande kennis oor die omvang van die probleem wat mense in die Goudveld ondervind met slagtery in die openbaar, wat die impak daarvan is op die alledaagse lewens van mense, en om voorstelle aan die hand te doen wat gebruik kan word wanneer regulasies opgestel word oor omgewingskwessies soos hierdie. Om hierdie oogmerke te bereik sal die volgende punte in hierdie studie aandag ontvang: • Suid-Afrika is 'n veelrassige land, so 'n beleid word benodig wat mense verenig. • Elke kultuur is uniek en het 'n besondere waarde, dus geen kultuur mag gemarginaliseer word nie. • Die bestaande beleid moet hersien en aangepas word. • Die werklike oorsake van die probleme moet geïdentifiseer word. Is hulle rassisties van aard, of gebaseer op werklike gesondheidsoorweginge ? In hierdie etiese studie is ook vasgestel dat die volgende kern-waardes die proses van besluitneming behoort te beïnvloed: • Gesondheid. • Respek en verdraagsaamheid. • Kommunikasie. • Deelname. • Deursigtigheid. • Verbintenis ("commitment"). Vanuit die bevindinge van die navorsing is dit duidelik dat albei die botsende partye (swart- en witmense) uiteindelik in vrede met mekaar moet saamleef, alhoewel hulle omskrywings van 'n vreedsame lewe verskil van mekaar. Gevolglik is die volgende aanbevelings gemaak om die probleem van slagtery in die openbaar aan te spreek: • 'n Formele byeenkoms moet saamgeroep word om die kritiese probleem te bespreek. • Skriftelike voorstelle moet vir so 'n byeenkoms opgestel word. • Die voorstelle moet bespreek word. • 'n Voorstel moet aanvaar word. • Die bestaande regulasies moet verander word.

Thesis (MScPhysio)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: Aims: To assess the effect of a vertical height adjustment of the chair and visual display unit (VDU) on work related upper quadrant musculoskeletal pain (WRUQMP) and sitting comfort in computer users. The upper quadrant refers to the occiput, cervical and upper thoracic spine including the clavicles and scapulae. Methods: An N=1 study was conducted using the ABC design whereby an ergonomic workstation adjustment, of VDU and chair height, was compared to the subject’s usual workstation settings. Pain and sitting comfort were measured using visual analogue scales (VAS). The subject was assessed over the four week phases as she performed her typical VDU work. The results were compiled and tabulated. Results: Both the mean and variance in pain intensity decreased after the workstation intervention. A deterioration was noted in sitting comfort. Conclusion: The vertical height adjustment of the chair and VDU may have contributed to a decrease in WRUQMP in this subject. This safe, economical workstation intervention may be a practical management option for the computer user suffering from WRUQMP. Further research into the measurement of comfort whilst sitting at a computer workstation, is recommended. / AFRIKAANSE OPSOMMING: Doelwitte: Om die effek te bepaal van n vertikale aanpassing van die stoel en beeldskerm van rekenaargebruikers op werksverwandte boonste kwadrant muskuloskeletale pyn en sitgemak. Die boonste kwadrant verwys na die oksiput, servikale en boonste torakale werwelkolom en sluit ook die klavikel en skapula in. Methode: Die N=1 studie is onderneem met gebruik van die ABC ontwerp in terme waarvan n ergonomiese aanpassing van stoel en beeldskerm vergelyk is met die normale gebruik van die deelnemer. Pyn en sitgemak is gemeet deur die gebruik van die Visueel analoogskaal. Die interwensies is ge-evalueer oor vierweekfases tydens normale rekenaar gebruik van die deelnemer. Die resultate is saamgestel en getabuleer. Uitkoms: Beide die gemiddelde en veranderlike pynintensiteit het verminder nadat die werkstasie aangepas is. Geen verbetering in sitgemak is opgemerk nie. Gevolgtrekking: Die vertikale hoogte-aanpassing van die stoel en beeldskerm het moontlik bygedra tot die verminderde pynvlakke in hierdie deelnemer. Hierdie veilige, ekonomiese verstelling is moontlik n praktiese beheeropsie vir rekenaargebruikers wat werksverwandte boonste kwadrant muskuloskeletale pyn verduur. Verder studie in die meet en waarneming van sitgemak tydens rekenaarwerk is nodig.

Thesis (MScPhysio)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: Aims: To assess the effect of a chair and computer screen height adjustment on the neck and upper back musculoskeletal symptoms in an office worker. Methods: An N=1 study was conducted using the ABC design. Ethics approval was obtained for the study and the participant provided informed written consent. The participant was assessed over three four week phases as she performed her habitual computer work. The outcome measures assessed during the three phases were the pain intensity and perceived sitting comfort. The three phases were named the baseline, intervention and wash-out phases. During the baseline phase, the outcome measures were obtained at the participant‟s habitual work station. The intervention phase involved a vertical adjustment of the chair and computer screen height. The wash-out phase allowed the participant to adjust the chair and computer screen height to their choice. A follow-up interview was conducted with the participant three months after completion of the study. The mean values and the ranges of the pain intensity and perceived comfort were obtained and compared. The data collected was captured on a Microsoft Excel 2010 spread sheet, where after the data was tabulated and presented graphically. Results: The mean pain intensity of the participant increased slightly during the intervention phase in comparison to the baseline phase, but remained stable during the wash-out phase. The mean perceived sitting comfort deteriorated initially during the intervention phase, but improved later during the intervention phase and showed greater improvement during the wash out phase. The perceived sitting comfort showed more improvement than the pain intensity during the washout phase. Both the pain intensity and perceived sitting comfort showed improvement at the three months follow up assessment, post completion of the study. Conclusion: The vertical height adjustment of the chair and the VDT did not improve the participant‟s pain intensity and perceived sitting comfort when compared to the participant‟s habitual workstation parameters. The findings do not favour the horizontal viewing angle. The findings of this study however support the use of „slightly below horizontal‟ viewing angle as being conducive to reduce the pain intensity and improve the sitting comfort of an office worker. / AFRIKAANSE OPSOMMING: Doelstelling: Om die effek te bepaal van die hoogte aanpassing van die stoel en rekenaarskerm op die nek en bo-rug muskuloskeletale simptome van 'n kantoorwerker. Metodes: „n N=1 studie was uitgevoer deur gebruik te maak van die ABC ontwerp. Etiese goedkeuring was verkry vir die studie en die deelnemer het ingeligte skriftelike toestemming verleen. Die deelnemer was ge-evalueer oor drie vier week-lange fases terwyl sy haar gewone rekenaarwerk verrig het. Die uitkomsmetings ge-evalueer tydens die drie fases was pyn intensiteit en waargenome sitgemak. Die drie fases was genoem die basislyn, intervensie en uitwas fases. Gedurende die basislyn fase was die uitkomsmetings by die deelnemer se gewone werkstasie ingevorder. Die intervensie fase het 'n vertikale aanpassing van die stoel en rekenaarskerm behels. Die uitwas fase het die deelnemer toegelaat om haar stoel en rekenaarskerm se hoogte aan te pas volgens haar keuse. 'n Opvolg onderhoud was gevoer met die deelnemer drie maande na die voltooiing van die studie. Die resultate was vasgelê op 'n Microsoft Excel 2010 data bladsy, waarna die data getabuleer en grafies uitgebeeld is. Resultate: Die gemiddelde pyn intensiteit van die deelnermer het effens toegeneem tydens die intervensie fase in vergelyking met die basislyn fase, maar het stabiel gebly tydens die uitwas fase. Die gemiddelde waargenome sitgemak het aanvanklik verswak tydens die intervensie fase, maar het later verbeter tydens die intervensie fase en het aangehou verbeter tydens die uitwas fase. Die waargenome sitgemak het groter verbetering getoon as die pyn intensiteit tydens die uitwas fase. Beide pyn intensiteit en waargenome sitgemak het verbetering getoon by die drie maande opvolg evaluasie, na voltooiing van die studie. Gevolgtrekking. Die vertikale hoogte aanpassing van die stoel en rekenaarskerm het nie die deelnemer se pyn intensiteit en waargenome sitgemak in vergelyking met die deelnemer se gewone werkstasie parameters verbeter nie. Hierdie bevindinge is nie ten voordeel van die horisontale kykhoek nie. Nietemin, ondersteun die bevindinge van hierdie studie die gebruik van die "effens onder die horisontale" kykhoek as bevorderend om die pyn intensiteit te verminder en die sitgemak van 'n kantoorwerker te verbeter.

Thesis (PhD)--Stellenbosch University, 2003. / ENGLISH ABSTRACT: The Plankenbrug River runs past the dense settlement of Kayamandi, on the outskirts of Stellenbosch. This site was chosen to study the impact of water pollution from formal and informal urban developments on water quality and associated health factors. Aims of the study: (1) To determine some basic epidemiological characteristics of the exposed population of Kayamandi, their sanitation problems and reasons for poor hygiene; (2) To determine the microbiological and chemical pollution load patterns in the Plankenbrug River over time; (3) To investigate the spectrum of organisms present in the river (other than the indicator E. coli) and their epidemiological implications for health; (4) To establish the possible presence of organisms resistant to chlorine or to antibiotics in the river below Kayamandi as indicators of environmental hazard. Methods: During the period 5 May 1998 to 10 February 2003 microbiological and chemical analyses have been carried out every 6 weeks on water samples obtained at various points along the Plankenbrug River. Two large surveys (n=2196 persons and n=3568 persons) of the community of Kayamandi have been undertaken and door-to-door education campaigns were carried out with the aid of trained community health workers. Results: Below Kayamandi the river contains dangerously high levels of faecal contamination and it constitutes a health hazard to all persons coming into contact with the water. Up to 13 million Escherichia coli per 100 ml water was recorded (cut-off level as indicator of human safety is 1000 organisms per 100 ml water). Not all the faecal contamination originated from Kayamandi. Substantial amounts of faecal contamination sporadically entered the river at different points below Kayamandi. The pollution load resulting from these intrusions were sometimes larger than that contributed by the whole of Kayamandi. Water samples below Kayamandi were screened to ascertain what other pathogens were present. Amongst the organisms were 0 haemolytic Streptococcus Group A and B, Mycobacterium intracellulare, Staphylococcus spp, Klebsiella spp., Pseudomonas spp. and many others. The list of pathogens found had such serious implications that a confidential health warning was sent out to health care centres and other affected organisations in the area. |3 haemolytic Streptococcus Group A has never before been reported as isolated in viable form from free-flowing natural waters. Signs of increased resistance to chorine were found in organisms isolated from the river water. There were also organisms showing signs of resistance to commonly used antibiotics. The E. coli organisms that survived various levels of chlorine treatment also showed increased resistance to amoxycillin when compared to untreated E. coli organisms sampled from the Plankenbrug River. During the community phase of the project in Kayamandi a reduction in the pollution levels occurred over the summers of 2000 and 2001 (note that "improved" does not yet mean "safe" by any means). This can be ascribed to the multi-pronged approach of the project. Attention was given to service and repair of sanitation facilities, a strong accent on door-todoor community education about better sanitation behaviour, creation of a central reporting point for blockages and breakages, and training of artisans (plumbers, bricklayers, etc) from the community to help with upkeep. The community showed encouraging signs of wanting better sanitation education. The improvement in pollution levels is however in danger of reverting back to the previous dangerous situation if better support and co-operation cannot be obtained from the relevant authorities. There were 16.9% of households who reported one or more cases of diarrhoea during the survey period (5 weeks) - a very high prevalence seeing that the survey was carried out during a wet and cold winter period. Conclusions: Active planning and other steps to cope with the sewage intrusions into the river should be instituted without delay. The water quality of the Plankenbrug River downstream from Kayamandi is extremely poor. The water constitutes a serious health hazard and a threat to downstream economic activities. The settlement of Kayamandi demonstrated that education, when coupled with maintenance and repairs of existing toilet facilities, can bring about a reduction in pollution loads, but that this should be an ongoing process and not be reduced to sporadic attempts. / AFRIKAANSE OPSOMMING: Die Plankenbrug Rivier vloei verby die digbewoonde nedersetting van Kayamandi aan die buitewyke van Stellenbosch. Hierdie plek is gekies as studie-area om die impak te bestudeer van waterbesoedeling wat van formele en informele dorpsontwikkeling afkomstig is, asook die geassosieerde gesondheidsfaktore. Doel van die studie: (1) Om sommige basiese epidemiologiese eienskappe van die blootgestelde populasie, hulle sanitasieprobleme en redes vir die swak higiene te bepaal; (2) Om die mikrobiologiese en chemiese besoedelingspatrone in die Plankenbrug Rivier oor tyd te bepaal; (3) Om die spektrum van organismes teenwoordig in die rivier (anders as E. coli) te bepaal asook hulle epidemiologiese implikasies op gesondheid; (4) Om vas te stel, as indikatore van omgewingsgevaar, of daar moontlik organismes teenwoordig is wat weerstandig is teen chloriene en antibiotika in die rivier onder Kayamandi. Metodes: Gedurende die afgelope vier jaar is mikrobiologiese en chemiese ontledings elke 6 weke uitgevoer van watermonsters wat van verskeie punte op die Palnkenbrug Rivier verkry is. Twee groot opnames is in die gemeenskap van Kayamandi ondemeem (n=2196 persone en n=3568 persone) en deur-tot-deur opvoedingsveldtogte is uitgevoer met die hulp van plaaslik opgeleide gemeenskapsgesondheidswerkers. Resultate: Onder Kayamandi bevat die rivier gevaarlike vlakke van fekale besoedeling en dit hou gesondheidsgevare in vir alle persone war daarmee in aanraking kom. Op tot 13 miljoen Escherichia coli per 100 ml water is genoteer (boonste grens van veiligheid vir die mens is 1000 organismes per 100 ml water). Nie al die fekale kontaminasie is afkomstig van Kayamandi nie. Substansiele hoeveelhede kontaminasie dring die rivier binne op verskillende punte ver onder Kayamandi. Hierdie besoedelingslading is soms groter as wat van die hele Kayamandi afkomstig is. Watermonsters geneem onder Kayamandi is ondersoek om vas te stel watter ander siekteveroorsakende organismes ook teenwoordig was. Onder die organismes gevind was (3 hemolitiese Streptococcus Groep A en B, Mycobacterium intracellulare, Staphylococcus spp., Klebsiella spp., Pseudomonas spp. en baie ander. Die lys van patogene wat gevind is, het sulke emstige implikasies dat 'n vertroulike gesondheidswaarskuwing uitgestuur is na gesondheidsdienspunte en ander geaffekteerde organisasies in die gebied. (3 hemolitiese Streptococcus Groep B is nog nie vantevore aangemeld as lewensvatbaar geisoleer uit vryvloeiende natuurlike waters nie. Tekens is gevind dat daar organismes in die rivier voorkom wat weerstandig is teen chloorbehandeling en ook teen algemeen gebruikte antibiotika. Die E. coli organisme wat verskillende konsentrasies van chloorbehandeling oorleeef het, het ook verhoogde weerstand teen amoksisilien getoon wanneer hulle vergelyk was met onbehandelde E. coli organisme wat van die Plankenbrug Rivier gemonster was. Gedurende die gemeenskapsfase van die projek is daar 'n verlaging van besoedelingsvlakke in die rivier gevind gedurende die somers van 2000 en 2001 (let op dat "verbetering" hier nog glad nie "veilig" beteken nie). Dit kan toegeskryf word aan die veelvlakkige benadering wat die projek gevolg het. Aandag is geskenk aan diens en herstel van sanitasiegeriewe met 'n sterk klem op deur-tot-deur opvoedingsveldtogte met die oog op beter sanitasiegedrag, skepping van 'n sentrale aanmeldpunt vir blokkasies en brekasies, en opleiding van ambagslui (loodgieters, messelaars, ens) uit die gemeenskap om te help met onderhoud. Die gemeenskap het bemoedigende tekens getoon dat hulle beter sanitasie opvoeding verlang. Die verbetering in die besoedelingsvlakke in die rivier loop egter gevaar om terug te val na die vorige gevaarlike vlakke as daar nie beter ondersteuning en samewerking van die onderhawige owerhede verkry kan word nie. Daar was 16.9% van huishoudings wat een of meer gevalle van diarree aangemeld het gedurende die 5 weke van die opnameperiode - 'n baie hoe prevalensie siende dat die opname uitgevoer was gedurende 'n nat en koue winterperiode. Gevolgtrekkings: Aktiewe beplanning en ander stappe om die riool-indringing in die rivier die hoof te bied is gebiedend noodsaaklik en behoort sonder versuim ingestel te word. Die waterkwaliteit van die Plankenbrug Rivier stroomaf van Kayamandi is baie swak. Die water hou emstige gesondheidsgevare in en is ook 'n bedreiging vir die ekonomiese aktiwiteite stroomaf. Die nedersetting van Kayamandi demonstreer ook dat opvoeding, wanneer gekoppel aan onderhoud en herstel van bestaande toiletgeriewe in verlaging teweeg kan bring van besoedelingsvlakke, maar dat dit 'n voortgesette program moet wees en nie net sporadiese pogings nie.

This thesis is based on a population study conducted to explore ethnic inequalities in cardiovascular disease using Hospital Episode Statistics (HES). The Hospital Episode Statistics have significant potential for health studies for ethnic groups, due to the large number of events from minority ethnic groups, comprehensive clinical information, full England coverage and fine geographical scale. However, the percentage of Finished Consultant Episodes (FCEs) with invalid ethnicity codes is at a high level. This thesis starts by developing a record linkage method and a coding rate method to improve the data quality of ethnicity codes in the HES. This thesis then further examines ethnic inequalities in cardiovascular disease incidence in England at both national and local geographical scales. The patterns of ethnic inequalities in cardiovascular disease appear to have changed little in the last ten years. However, large variations of geographical relative risk of cardiovascular disease were observed for ethnicity-sex groups. The relationships between areal socioeconomic status measured at different geographical scales and ethnic inequalities in different types of cardiovascular disease were also explored. As there are very limited data on the mortality of minority ethnic groups in the UK, few studies have compared the incidence and outcome of cardiovascular disease from the same population. This thesis came up with some novel findings, for example, that people from minority ethnic groups, who generally have increased risk of cardiovascular disease incidence, have better cardiovascular disease survival than white people. The contribution of areal socioeconomic status, distance to treatment sites and cardiovascular disease severity and treatment to the ethnic inequalities in cardiovascular survival was examined. The relationships between socioeconomic status measured at different geographical scales and ethnic inequalities in cardiovascular disease severity and treatment were investigated in this thesis as well.

Three trends are occurring today in the United States which inspired this research. First, America is growing increasingly urbanized. Today, more Americans are living in cities than in rural environments, and this pattern is predicted to continue for the foreseeable future. Urban living has benefits, but there are also challenges for city residents including pollution, traffic, and crime. As social scientists, we need to improve our understanding of urban dwellers' relationship with their natural environment just as biophysical scientists are focusing more and more on the impacts of urban development on the natural world. Second, Americans are spending less time recreating outdoors. There has been a documented decline of participation in nature-based recreation, likely being replaced by an increase in use of electronic media during people's leisure time. Less contact with nature has consequences for people, perhaps especially for city dwellers who spend the majority of their time surrounded by the built environment of concrete and asphalt. It is likely that reliance on electronic entertainment has played a substantial role in decreasing amounts of physical activity. Lastly, Americans are becoming more sedentary. Today, the number of Americans who report getting no physical activity is about equal to the number who report getting regular physical exercise during their free time. Rising rates of obesity for adults and children in the U.S. have raised considerable concerns among medical and public policy professionals. The purpose of this research was to examine how small-scale urban nature parks are affecting city residents in Portland, OR. I looked at three elements of Portland residents' relationship with urban nature parks. First, I looked at whether there was an association between individual physical and psychological health and park use. Prior research has revealed that people who spend time recreating outdoors tend to be more physically active than people who do not. These observed higher levels of physical activity are associated with improved physical health. Time in nature settings has also demonstrated a positive effect on psychological well-being, such as reduced anxiety and improved ability to concentrate. Second, I examined whether having a nature park in their community had an effect on Portland residents' sense of neighborhood health. Previous research suggests that having natural areas in urbanized areas directly contributes to city residents' sense of a stronger, healthier community. Green space in cities has been associated with not only higher levels of reported satisfaction with the neighborhood, but also with higher property values, and with higher levels of retail spending. Third, I employed a social psychological model of attitude formation to evaluate Portland residents' attitudes about their nature parks. Attitudes are particularly important for natural resource managers to understand and account for in policy decisions since management of natural resources often engages the public's sense of personal freedoms and concerns over government regulations. Furthermore, because people in cities are so closely in contact with urban green space on a regular basis, inclusive and responsive policy requires that managers take account of public attitudes. I collected the data relating to these three elements of the relationship between urban residents and their nature parks in Portland because it is the largest city in Oregon. I obtained the data through a general population survey, randomly distributed to residents in the Portland metropolitan area during the fall of 2010. I conducted customary social science statistical analysis, including linear regression, to assess the relationship between Portland nature parks and personal and community health. To evaluate my sample's attitudes, I used the tripartite model of attitude formation originally developed in social psychology research. Because I was working with latent factors of attitude formation, I used structural equation modeling to assess the relationship of the observed variables to their latent factors, and the relationship among the latent factors. My results largely agree with those of other researchers, though I approached the question of physical health and nature recreation slightly differently. For my work on physical health, rather than ask about physical activity and infer health outcomes, I asked directly about physical health. I tested two hypotheses. One hypothesis was that there would be a positive association between self-reported physical health and park use, and the other tested for a positive association between park use and psychological health. My hypothesis for the physical health-parks relationship was partially supported. I tested two physical health variables, and found that one, which described overall health, did reveal a statistically significant relationship to park use. The other, relating to role limitations due to physical health problems, did not have a significant relationship to park use. My second hypothesis asserted that there would be a positive relationship between psychological health and park user status. This hypothesis was not supported, but I did find indications of an association between psychological health and park use. The second element of the relationship between city residents and urban nature parks related to neighborhood health. My results from this analysis were consistent with prior research findings which tend to support a positive association. I tested whether parks close by respondents homes (a fifteen to twenty minute walk), and parks farther away (no more than a ten minute drive away from home) were positively associated with self-reported neighborhood health. I found that both levels of proximity were positively associated with perceptions of neighborhood health. Because prior research suggests that one of the ways that neighborhood green spaces promote stronger communities is through the social interactions that occur in parks among neighbors, I also tested whether park-related social interaction was positively associated with community health ratings. In testing for a mediating effect of social interaction on the relationship between parks and neighborhood health, I found that park-related social interaction had a partial mediating effect on neighborhood health ratings for both parks within walking distance and within driving distance. In testing for moderation, I found that the moderation effect of social interaction was present only for parks within walking distance. The third and final element of the relationship between urban nature parks and city dwellers was attitudes about urban nature parks. I employed a model of attitude formation originally proposed in the social psychology literature. The tripartite model argues that an attitude is formed through three precursors: the cognitive, the affective, and the behavioral components. I also included an additional variable for social networks which I proposed would act as a moderating variable on the relationship between the other components and park attitude. My results for the entire, combined sample of both park users and nonusers indicated that both the cognitive factor and the affective factor have a significant association with attitude formation, while the behavioral component did not. The model for the combined sample also showed that social networks had a statistically significant, inverse relationship with attitudes. I conducted a test for attitude differences between groups (users and nonusers), and found a statistically significant difference. I also tested for a moderating effect of social networks on the other attitude formation components, but that relationship was not supported. Finally, I conducted comparisons between the two groups to assess any differences in the attitude components between users and nonusers. Side-by-side comparisons revealed that both users' and nonusers' attitudes were significantly influenced by the affective component. Perceived outcomes of park use was not predictive of attitude for either group. The values component (on an anthropocentric-biocentric scale) was significant for users, but not nonusers. Nonusers attitudes were also significantly impacted by the behavioral component (i.e., behaviors related to parks), and by social networks. Social networks were not predictive of users' park attitudes. The research I have presented herein provides support for the hypotheses that time spent in natural settings is associated with better physical and psychological health and that community green spaces contribute to satisfaction with one's neighborhood. I also found that attitudes about parks differed between users and nonusers, yet both groups valued them as benefits in the urban environment. Since my sample size was insufficient to make generalizable statements about Portland's population, my results are suggestive, but are consistent with prior research. My research results can help urban natural resource managers and city decision-makers make more inclusive decisions by incorporating an understanding of city residents' relationships to urban nature parks. The results of my research on personal and community health support the position that urban green space fulfills an important function by providing valuable public health benefits, and promoting healthier, more "livable" communities. My results indicate that, for my sample, social interaction at parks was positively related to neighborhood health. Such a positive association suggests that parks could be leveraged to build community cohesion which ultimately leads to benefits like increased sense of safety and happier residents. My results pertaining to park attitudes can help managers develop more targeted public outreach campaigns. For instance, I found that for park nonusers, social networks were a statistically significant predictor of park attitudes. This result implies that park staff and managers could benefit by identifying community organizations and business associations that might be conduits to reach nonusers. Through such information pathways, park managers could disseminate information about urban nature parks that could attract current nonusers. Urban nature parks are not the sole answer to building healthier communities and people. They cannot alone reverse social ills that many urban neighborhoods contend with routinely. However, the scientific data do support the idea that urban natural spaces like nature parks are positively associated with personal and community health. With careful participatory planning that includes a substantial public input component, urban natural resource managers could develop urban nature parks as part of a city's green infrastructure that not only provides valuable ecosystem services like cleaner water and reduced energy consumption, but also provides for nature-based recreation experiences that promote healthier, happier city residents. / Graduation date: 2012

For many decades, the World Health Organisation had highlighted the growing importance of chronic non-communicable diseases in developed and developing countries, with an increase in lifestyle-related diseases. Physical inactivity has been identified as one of the risk factors, in addition to other leading risk factors like diet, and the use of tobacco and alcohol, contributing to the occurrence of non-communicable diseases like cardiovascular diseases, cancers, obesity and type 2 diabetes mellitus. Based on the researcher's observations while living in Belhar community for more then ten years, it was hypothesized that the level of physical inactivity among adolescents could become a public health problem in the future if not addressed immediately.

<p>Regular physical activity is linked to enhanced health and to reduced risk for mortality and the development of many chronic diseases in adults. However, many adults are either sedentary of less physically active. Children and adolescents are more physically active than adults, but participation in physical activity declines with age during adolescence. Girls are less active than boys, older children and adolescents are less active than younger children, and among girls, blacks are less active than whites. This study aimed to examine physical activity in female learners attending Kagiso Township high schools in Gauteng Province.</p>

Thesis (M Sport Sc (Sport Science))--Stellenbosch University, 2011. / ENGLISH ABSTRACT: Adolescence is the period between childhood and adulthood. This phase starts between the ages of 11 and 13 years and ends between 17 and 21 years. Adolescence was seen as a phase of development, growth and excellent health in the past, but that is not the case in the 21st century. The health of adolescent are being influenced by technology such as computers and televisions, crime, poor eating habits, the absence of Physical Education at schools, urbanization, overpopulation and less available space for children to play. These aspects lead to a sedentary lifestyle which may impact their health in the form of hypokinetic diseases. The primary aim of this study was to determine the lifestyle patterns of adolescents in selected Western Cape high schools. The secondary aims of this study were to determine the lifestyle patterns of different ethnic groups; those of boys and girls; and to compare these lifestyle patterns with those of adolescents 10 years ago. In this study, two questionnaires were used for data collection: a questionnaire for the adolescents; and one for the Life Orientation teachers. The high schools (N=30) were randomly selected to partake in the study. Out of each school learners (N=60) were also randomly selected to partake in the study. The 60 learners consisted of [n=15] boys and [n=15] girls in Grade 9 and [n=15] boys and [n=15] girls in Grade 11 between the ages of 15 and 17 years. One Life Orientation teacher was also randomly selected from each school. Data from the two questionnaires were coded in computer format and statistically analysed with the computer program Stasoft Statistica Version 10. From the results of the study it can be concluded that neither White nor Coloured adolescents found school sport important nor they did not partake in sporting activities on a regular basis. Adolescent boys, on the other hand, were found to be much more active than adolescent girls. Adolescent girls preferred sedentary activities like listening to music and reading books. Both White and Coloured adolescents, and boys and girls, found their health to be excellent despite the fact that research showed the opposite to be true. White adolescents also found socialising more important than Coloured adolescents. Coloured adolescent on the other hand found household chores more important. Boys and Coloured adolescents attended self defence classes on a regular basis. This study is a follow-up study on one conducted by Van Deventer in 1999. It serves as a basis for further research and it is recommended that a new study should be conducted every 10 years to determine changes in the lifestyle patterns of adolescents so that it can be addressed. Further research is recommended because of the low feedback of Life Orientation teachers to determine and address the status of Life Orientation presently in schools, the attitudes of teachers and learners toward Life Orientation, Education and training of Life Orientation teachers, apparatus and facilities needs and time allocation towards the movement component in Life Orientation. Further research is also recommended because of the insufficient feedback received from Black learners. It is also important to determine their lifestyle patterns so that recommendations in this regard can be made. / AFRIKAANSE OPSOMMING: Adolessensie is die periode tussen die kinderjare en volwassenheid. Die fase begin tussen die ouderdomme van 11 en 13 jaar en eindig tussen 17 en 21 jaar. Adolessensie is vroeër as 'n fase van groei, ontwikkeling en goeie gesondheid beskou maar dit is nie meer die geval nie. Adolessente se gesondheid word huidig deur beskikbare tegnologie soos televisie en rekenaars, vervoer, misdaad, verstedeliking, minder sportgronde as gevolg van oorbevolking, gebrekkige Liggaamlike Opvoeding by skole en ongesonde eetgewoontes belemmer. Dit kan tot sedentêre leefstylpatrone aanleiding gee wat hipokinetiese siektes kan meebring. Die hoofdoel van die studie was om die leefstylpatrone van adolessente in geselekteerde hoërskole van die Wes-Kaapse Onderwysdepartement te bepaal. Daar was ook op die volgende subprobleme gefokus: die vergelyking van die leefstylpatrone van verskillende etniese groepe, die vergelyking van die leefstylpatrone van seuns en meisies en die vergelyking van die leefstylpatrone van huidige adolessente met dié van 10 jaar gelede. Twee vraelyste was vir die insameling van die data gebruik. Een wat leerders en die ander die Lewensoriëntering-onderwyser voltooi het. Die hoërskole (N=30) was ewekansig geselekteer. Uit elke hoërskool was leerders (N=60) ewekansig: uit Graad 9 [n=15] seuns en [n=15] meisies en uit Graad 11 [n=15] seuns en [n=15] meisies tussen die ouderdomme van 15 en 17 geselekteer. Een Lewensoriëntering-onderwyser per skool was ook ewekansig geselekteer. Die data wat vanaf die vraelyste verkry was, is in rekenaarformaat gekodeer en statisties verwerk. Stasoft Statistica Weergawe 10 is vir verdere dataverwerking gebruik. Daar is tot die gevolgtrekking gekom dat beide Wit en Bruin adolessente sport as onbelangrik geag het en ongereeld daaraan deelneem het. Adolessente seuns het sport belangriker geag en ook meer gereeld as adolessente meisies daaraan deelgeneem. Adolessente meisies het sedentêre aktiwiteite, soos om te lees en na musiek te luister, belangriker as adolessente seuns geag. Wit en Bruin adolessente, en die seuns en meisies, het hul gesondheid goed geag al bewys navorsing die teendeel. Wit adolessente het meer as Bruin adolessente gesosialiseer, terwyl Bruin adolessente huishoudelike take belangriker as Wit adolessente geag het. Adolessente seuns en Bruin adolessente het gereeld selfverdedigingsklasse bygewoon. Die onderhawige studie is 'n opvolgstudie wat deur Van Deventer in 1999 uitgevoer is en dien as rigtingwyser vir verdere navorsing. 'n Opvolgstudie elke 10 jaar is ideaal sodat die veranderinge in leefstylpatrone onder adolessente gemonitor en aangespreek kan word. Verdere navorsing word as gevolg van die lae terugvoersyfer van Lewensoriënteringonderwysers aanbeveel sodat die volgende aangespreek kan word: die status wat Lewensoriëntering huidig geniet; die gesindheid van onderwysers en leerders teenoor Lewensoriëntering; onderwyseropleiding; apparaat en fasiliteit behoeftes; en die tydstoekenning vir die bewegingskomponent van Lewensoriëntering. Verdere navorsing word as gevolg van die lae terugvoersyfer van Swart adolessente aanbeveel sodat hul leefstylpatrone ook bepaal en aanbevelings daarvolgens gemaak kan word.
