This study examined lifestyle changes as related to the risk of coronary heart disease (CHD) in Chinese students at Oregon State University (OSU). The study population included male students or scholars from the People's Republic of China who were attending OSU during spring term 1992. Fifty subjects were interviewed using a structured questionnaire. The questionnaire included eight categories of information: (1) bodyweight and blood pressure, (2) diet, (3) alcohol consumption, (4) cigarette smoking, (5) physical activity, (6) psychological stress, (7) acculturation factors, and (8) demographic factors. Results indicated that for this group of Chinese students, bodyweight, consumption of dietary fat, dairy products, soft drinks, and psychological stress had increased significantly during their stay in the US. Meanwhile, the level of physical activity had decreased. These changes, especially if continued, may have the potential to increase their risk of developing CHD. On the other hand, there were no significant changes in blood pressure and alcohol consumption. For cigarette smokers, smoking had decreased. In their responses to the open-ended questions, the reasons given for bodyweight changes included diet, decreased physical activity, and increasing age. Diet changes were attributed to food availability, relative price, and convenience. For decreased cigarette smoking, lack of smoking environment was considered to be the most important factor. Automobile use, limited spare time, and no friend to play with were the reasons for decreased physical activity. Finally, pressure in school, financial difficulty, and worrying about future were considered to be the reasons for increased psychological stress. Multiple regression analysis indicated that the length of US stay and decreased physical activity were significant predictors for bodyweight gain. The length of US stay was also a significant predictor for changes in total dietary fat. Having financial aid from school was associated with decreased physical activity. Living as single was significantly associated with increased psychological stress. This study failed to identify any significant associations between acculturation factors and changes in the CHD risk factors. / Graduation date: 1993

Earthquakes are among the most devastating and unpredictable of natural hazards that affect civil infrastructure and have the potential for causing numerous casualties and significant economic losses over large areas. Every region that has the potential for great earthquakes should have an integrated plan for a seismic design and risk mitigation for civil infrastructure. This plan should include methods for estimating the vulnerability of building inventories and for forecasting economic losses resulting from future events. This study describes a methodology to assess risk to distributed civil infrastructure due to large-scale natural hazards with large geographical footprints, such as earthquakes, hurricanes and floods, and provides a detailed analysis and assessment of building losses due to earthquake. The distinguishing feature of this research, in contrast to previous loss estimation methods incorporated in systems such as HAZUS-MH, is that it considers the correlation in stochastic demand on building inventories due to the hazard, as well as correlation in building response and damage due to common materials, construction technologies, codes and code enforcement. These sources of correlation have been neglected, for the most part, in previous research. The present study has revealed that the neglect of these sources of correlation leads to an underestimation of the estimates of variance in loss and in the probable maximum loss (PML) used as a basis for underwriting risks. The methodology is illustrated with a seismic risk assessment of building inventories representing different occupancy classes in Shelby County, TN, considering both scenario earthquakes and earthquakes specified probabilistically. It is shown that losses to building inventories estimated under the common assumption that the individual losses can be treated as statistically independent may underestimate the PML by a factor of range from 1.7 to 3.0, depending on which structural and nonstructural elements are included in the assessment. A sensitivity analysis reveals the statistics and sources of correlation that are most significant for loss estimation, and points the way forward for supporting data acquisition and synthesis.

Background: Fall injuries are a costly problem for society, with costs ranging up to 14 billion a year. In addition to economic loss accidental falls also creates human value losses and reduced quality of life for its victims. In order to prevent the occurrence of injury related to accidental falls healthcare providers utilize various scientifically developed risk assessment tools, one of them being Downton Fall Risk Index. Method: Empirical, quantitative cross-sectional study. Objective: The purpose of the extended essay was to describe the categories in Downton Fall Risk Index that have a bearing on patients' risk of falling while in hospital and in municipal care, and to illustrate how nurses can use the fall risk assessment tool. Results: Of the 708 participants a total of 73% had a high risk of falling according to Downton Fall Risk Index, of the patients being treated at a hospital 66% had high risk of falling and of the patients being treated in municipal care 87% had high risk of falling. Downton Fall Risk Index indicates that the medication was by far the largest category and included 576 patients (81%), followed by sensory impairment in 474 patients (67%). 335 patients (47%) had fallen previously. Discussion: Previous studies show that among patients being treated in hospitals, between 1.3 to 2.1% will fall. Downton Fall Risk Index indicates that 66% of the group of patients are at high risk of falling. This may be due to the fact that Downton Fall Risk Index focuses too much on medication. It is the nurse’s responsibility to coordinate work around the patient in order to minimize the risk of falling. For example, contact an occupational therapist or an ophthalmologist who can undertake specific actions to reduce patients' risk of falling. Nurses should also use appropriate risk assessment tools to identify risk factors in the patient and then use these to formulate a nursing diagnosis. Conclusion: Downton Fall Risk Index is too sensitive to be used on hospitalized patients, the instrument works better in patients being treated in municipal care. It is important that the nurse can use scientifically designed tool for ensuring good health care for the patient, tools such as the fall risk assessment tool. / Bakgrund: Fallskador är ett dyrt problem för samhället med kostnader som sträcker sig upp mot 14 miljarder kronor om året i Sverige. Förutom ekonomiska förluster skapar fall även humanvärdesförluster och försämrad livskvalitet för den drabbade. För att förhindra uppkomsten av fallskador används inom sjukvården olika vetenskapligt framtagna fallriskbedömningsinstrument, ett av dessa är Downton Fall Risk Index. Metod: Empirisk, kvantitativ tvärsnittsstudie. Syfte: Syftet med fördjupningsarbetet är att beskriva vilka kategorier i Downton Fall Risk Index som har betydelse för patienters fallrisk vid vistelse på sjukhus och vid kommunal vård, samt att belysa hur sjuksköterskan kan använda Fallriskbedömningsinstrument. Resultat: Av de 708 medverkande hade totalt 73% hög risk att falla enligt Downton Fall Risk Index, på sjukhus hade 66% av patienterna hög risk att falla och i kommunal vård hade 87% av patienterna hög risk att falla. Downton Fall Risk Index anger att medicinering var den klart största kategorin och inkluderade 576 av patienterna (81%), därefter kom sensorisk funktionsnedsättning med 474 patienter (67%). 335 patienter (47%) hade fallit tidigare. Diskussion: Tidigare studier visar att på sjukhus faller mellan 1,3-2,1% av patienterna. Downton Fall Risk Index anger att 66% av samma patientgrupp har hög risk för fall. Detta kan bero på att Downton Fall Risk Index fokuserar för mycket på medicinering. Det är sjuksköterskans uppgift att samordna arbetet runt patienten så att fallrisken minimeras. Till exempel ska sjuksköterskan kontakta arbetsterapeuter eller ögonläkare som kan utföra punktinsatser för att minska patientens fallrisk. Sjuksköterskan ska även använda fallriskbedömningsinstrument för att identifiera riskfaktorer hos patienten och sedan använda dessa för att utforma en omvårdnadsdiagnos. Slutsats: Downton Fall Risk Index är alldeles för känsligt för att kunna användas på patienter inneliggande på sjukhus, instrumentet fungerar bättre på patienter inneliggande i kommunal vård. Det är viktigt att sjuksköterskan kan använda vetenskapligt utformade verktyg för att säkerställa en god omvårdnad för patienten, verktyg såsom Fallriskbedömningsinstrument.

The intensifying nature and extent of disasters together with the associated devastation and astronomical costs required to manage the rippling effects of disasters, enunciates the national and international focus on disaster risk reduction. Further the ever evolving and complex dynamics of risk as the decisive contributor to disasters has heightened the urgency to pursue effective disaster risk assessment as a prerequisite to inform the disaster risk management planning and disaster risk reduction intervention processes. A structured and systematic approach to disaster risk assessment assists in maintaining rigour thus promoting the quality and validity of the process and its outcomes. Appropriate models serve as valuable tools in enabling this methodological perspective to undertake disaster risk assessment. The nonexistence of an appropriate disaster risk assessment model in South Africa has initiated the emphasis and purpose of this study thereby underscoring the critical need for the development of an effective, holistic and integrated disaster risk assessment model for local government in South Africa. In spear heading the process towards the development of an appropriate disaster risk assessment model, the research commenced with establishing and asserting the fundamental link between disaster risk assessment and disaster risk reduction as an avenue to contextualise and ground the key issues in effective disaster risk reduction. The exploratory analysis engaged in presenting a theoretical construct of disaster risk assessment examined the core components informing the disaster risk assessment process. This discussion led to the comparative review of three disaster risk assessment models viz the Community-Wide Vulnerability and Capacity Assessment (CVCA) Model, the Community-Based Risk Reduction Model and the South African Disaster Risk Assessment Model interrogating the significant characteristics, structure and application of the models. The results of the comparison of the above three models provided the necessary insight for the development of the disaster risk assessment model for local government in South Africa. Further influenced by the outcomes of the applied research on the critical analysis of the current disaster risk assessment practice within the four selected municipalities representing local government in South Africa; viz eThekwini Metropolitan, Ekurhuleni Metropolitan, Bojanala District and Stellenbosch local Municipalities. Through the data coding, classification and interpretive process, constructive and correlated research findings were immanent guiding the final development of the integrated disaster risk assessment model for local government in South Africa. / Thesis (Ph.D. (Public Management and Administration))--North-West University, Potchefstroom Campus, 2012

The existing audit risk model does not take business risk into account. The aims of this study are, firstly, to do research on the necessity of taking business risk into account in the audit risk model, and secondly, to indicate the influence of business risk on the audit risk model and on the scope of an audit. In this study, both audit and business risks were researched and it was determined that the existing audit risk model only considers the probabilities that auditors can give incorrect opinions. This study proposes a method whereby an auditor can consider both his own business risk and that ofhis client in determining an audit risk that is acceptable to him and in determining the scope ofhis audit. In addition to the probabilities of incorrect decisions by auditors the consequences thereof are also considered, thus limiting the auditor's engagement risk. / Die huidige ouditrisikomodel neem nie besigheidrisiko in ag nie. Die doel van hierdie studie is eerstens, om die noodsaaklikheid van die inagnerning van besigheidsrisiko in die ouditrisikomodel te ondersoek en tweedens, om die invloed van besigheidsrisiko op die ouditrisikomodel en op die omvang van 'n oudit aan te dui. In hierdie studie is literatuur oor ouditrisiko en besigheidsrisiko ondersoek waaruit aan die lig kom dat die huidige ouditrisikomodel net die waarskynlikhede in ag neem dat ouditeurs foutiewe menings kan uitspreek. Gevolglik stel die studie 'n metode voor waardeur 'n ouditeur beide sy eie besigheidsrisiko asook die van sy klient in ag kan neem tydens die bepaling van 'n ouditrisiko wat vir hom aanvaarbaar is en tydens die vasstelling van die omvang van sy oudit. Daardeur word nie alleen die waarskynlikhede nie, maar ook die gevolge van foutiewe besluitnemings deur ouditeurs oorweeg en 'n ouditeur se aanstellingsrisiko sodoende beperk. / Auditing / MCom (Ouditkunde)

As the leading cause of death in the United States, coronary heart disease (CHD) is a growing public health problem, despite the fact that many risk factors for the disease are preventable, especially if addressed early in life. The purpose of the current study was to examine the effects of loss-framed versus gain-framed versus information-only health messages on both intention to attend and actual attendance at an appointment to get screened for CHD risk factors (i.e., hypertension, diabetes, and dyslipidemia). It was hypothesized that a population of young adults would be more likely to view screening for CHD risk factors as a low-risk, health-affirming behavior as opposed to a risky, illness-detecting behavior and would thus be more strongly influenced by gain-framed messages than loss-framed messages. Additional goals included the exploration of the extensively researched individual health beliefs of perceived threat (as defined by the health belief model) and health locus of control as they relate to message frames. One hundred forty-three undergraduate students were randomly assigned to either the loss-framed, gain-framed, or information-only control conditions. Framing manipulation checks revealed that participants failed to discern differences in the tone and emphasis of the experimental pamphlets. As a result, no tests of framing effects could be conducted. Sixteen (11.2%) of the 143 participants who participated in Part 1 of the experiment participated in Part 2 (i.e., attended a risk factor screening appointment). Multiple regression analysis revealed risk index, age, and powerful others health locus of control as significant predictors of screening intention. Gender was the only demographic or health related variable that was significantly related to screening outcome, such that women were more likely to get screened than men. Limitations and recommendations are discussed.

The aim of the project was to make a detailed risk assessment using Swedish guidelines for a factory site in Kodaikanal, South India, and a nearby village called Vellagavi. The study areas were chosen due to previous records of mercury contamination on the factory site and a possible spread to Vellagavi. A comparison between Indian and Swedish guidelines for risk assessment of contaminated areas was performed. The purposes of comparing the two systems were to locate if there were any differences in the legislation, or guidelines, and to find ways of improving the processes. The project also included an evaluation of possible remedial actions that could reverse or prevent environmental damage that might be caused by the former factory. Methods used for the project were literature studies, semi-structured interviews and surveys. The results from the risk assessment were that the Swedish Computer Program for Calculation of Guideline Values (CPCGV), with some adjustments, could be used in order to calculate site specific guideline values for mercury concentrations on sites similar to Swedish conditions, such as climate. The site specific guideline values in soil rangedfrom 0.1-2.4 mg/kg. An Indian court decision had stated that a guideline value of 20 mg/kg should be used for remediation at the factory site. The result from the forward dose calculation showed that when a soil contains 20 mg/kg,the tolerable daily intake of mercury would be exceeded, and therefore pose a risk to human health. The comparison of legislation systems between India and Sweden showed several differences. India did not have any legislation relating directly to polluted soil. Risk assessments in India commonly relied on several different international standards even though the standards were not regulated by law. The results from the remedial evaluation showed that there were several possible remediation methods that could beused on the factory site. Limited remedial actions were suggested for Vellagavi since there were no measurements taken on site. Preferably, remediation should take place at the source of the contamination, i.e. the factory site. / Det övergripande målet med projektet var att genomföra en detaljerad riskbedömning för en fabriksplats i Kodaikanal, södra Indien, samt för en närliggande by, Vellagavi. Tidigare genomförda mätningar uppvisade förhöjda halter av kvicksilver i området, varför det ansågs vara ett lämpligt område för studien. Studien innehöll en jämförelse av riktlinjer för riskbedömningar för förorenad mark mellan Indien och Sverige där syftet var att identifiera skillnader i lagstiftning och riktlinjer samt lokalisera eventuella förbättringsmöjligheter. Studien innefattades även av en åtgärdsutredning för fabriksplatsen och Vellagavi, vars syfte var att utreda vilka åtgärder som skulle kunna minska risken för fortsatt miljöförstöring eller återställa området. Metoderna som användes i studien var litteraturstudier, semi-strukturerade intervjuer och en enkätundersökning. Resultatet från riskbedömningen visade att beräkningsverktyget för platsspecifika riktvärden från Naturvårdsverket kunde användas på platser som liknar Sverige klimatmässigt, efter att diverse justeringar hade gjorts. Beräkningsverktyget användes för att ta fram ett platsspecifikt gränsvärde för kvicksilverkoncentrationen i marken. Det framtagna platsspecifika gränsvärdet för koncentrationen kvicksilver i jord varierade mellan 0,1-2,4 mg/kg. Ett beslut utfärdat av indisk domstol angav att fabriksplatsen skulle saneras så att kvicksilverkoncentationen i marken inte skulle överskrida 20 mg/kg. Resultatet från den här studien visade att den nivån av förorening i marken skulle innebära att det tolerabla dagliga intaget av kvicksilver skulle överskridas. En jämförelse av de juridiska systemen som anknöt till förorenad jord i Indien respektive Sverige visade på flertalet skillnader mellan länderna. Indien hade ingen lagstiftning som speficikt reglerade förorenad jord medan det i Sverige reglerades av Miljöbalken. Riskbedömningar i Indien baserades ofta på internationella standarder, med det fanns ingen lagstifting som reglerade vilka standarder som skulle användas. Resultatet från åtgärdsutredningen var att det fanns flera olika åtgärdsmetoder som skulle kunna användas för att sanera fabriksplatsen. Åtgärdsutredningen för Vellagavi var begränsad eftersom det inte fanns tillräckligt mycket mätdata för området. Företrädesvis bör saneringsåtgärderna vidtas vid föroreningskällan, vilket i detta fall är fabriksplatsen.
