Effect of Neighborhood Features on BMI of African American adolescents in South Los Angeles

Obiora, Francisca Omelogo 01 January 2015 (has links)
Childhood obesity is a major national and worldwide public health crisis. The occurrence of childhood obesity, caused to large extent by an imbalance between caloric intake and caloric expenditure, has increased in the last 30 years. Although the prevalence of obesity has stabilized in recent years, it remains a top public health concern in the United States, especially in urban centers. The purpose of this study was to examine the associations between diet, physical activity, and the built environment in relation to the mean body mass index (BMI) of adolescents aged 12 to 17 years living in South Los Angeles, California. The research design, methods, and data analysis were based on the California Health Interview Survey 2007-2013 dataset. This database was mined for the independent variables: physical security, food insecurity, parental education and income, and availability of recreational facilities necessary for a healthy lifestyle; the dependent variable was BMI. Descriptive statistics and multiple regression analysis were used in analyzing for the association between the dependent variable and the independent variables. The outcomes of this study showed no associations between neighborhood physical security, recreational facilities, adolescent's physical activity, parents' education level, parents' income level, and BMI. However, the results did show a significant correlation between adolescent's dietary intake, food security, and BMI. This study will contribute to positive social change by informing public health officials and policy makers of the benefits of food security to healthier eating habits and BMI among the adolescents studied. Resulting actions could result in collaborative efforts toward reduction and prevention of childhood obesity.

Satisfação de vida, estilos parentais e personalidade em militares e universitários

Rosa, Francisco Heitor da January 2006 (has links)
A influência ambiental é tida como certa no desenvolvimento humano. Contudo, alguns ambientes específicos exercem influências tardias no desenvolvimento. A psicologia militar tem se estabelecido como campo de pesquisa e atuação profissional desde a Primeira Grande Guerra, principalmente nos Estados Unidos e Europa. O ambiente militarizado, costumeiramente relacionado com a fase adulta de vida, tem sido pouco estudado no Brasil, suscitando uma lacuna importante de conhecimentos psicológicos. Neste estudo, cadetes da Academia Militar das Agulhas Negras (N=373) e universitários (N=73) responderam instrumentos psicológicos sobre bem-estar subjetivo, estilos parentais e personalidade. Para fins de análise, a amostra militar foi subdividida por diversos critérios: ter pai militar, ter estudado em Colégios Militares, ter parentes militares (que não o pai). Diferenças significativas foram encontradas entre a amostra militar e universitária e entre filhos de militares e não-filhos de militares. Filhos de pais militares apresentaram maior satisfação de vida e maior freqüência de pais e mães responsivos que outros cadetes. Ex-alunos de Colégio Militar mostraram-se mais autônomos e propensos a novas experiências, além de melhor adaptação ao meio militar. Observou-se que a pontuação na escala de Afiliação foi significativamente mais alta entre os militares, entre outras diferenças nas escalas do IFP, mas não houve diferença na Escala de Desejabilidade Socia!. Os resultados apontam a necessidade de novos estudos na área e com diferentes populações. / There seems to be no doubt that the environment has an influence in human psychological development. Nevertheless, it also seems that some specific environments may have an influence in development later on life. Military Psychology was established as research and work field since World War I, mainly at United States and Europe. The military environment, usually related to the adult stage of life, has received little attention from Brazilian psychologists and little is known of its effects in our country. The present study attempts to fill this gap investigating possible psychological differences between persons who live in a military environment and those who do not have any contact with it. Participants were 373 male students at Academia Militar de Agulhas Negras (a military school for training officers for the Brazilian army) and 73 male undergraduate students who never had any contact with a military environment. The military sample was further divided into groups of students who 1) have studied in military schools, 2) have a parent serving in the armed forces, and 3) have other relatives serving in the armed forces. The participants responded to scales to assess subjective well-being, parental styles, and personality traits. The results showed significant differences between the military and the undergraduate sample and between participants who had a father serving at the armed forces and those who did not. Participants whose father was serving presented higher subjective well-being scores and perceived their father and mother as more authoritative. Those who had studied at military secondary schools presented more autonomy and were more open to new experiences. The non-military undergraduate participants tended to perceive their parents as more authoritarians. Affiliation scale score was higher to army cadets, among other significant differences, but Social Desirability scale shown no difference. The results stress the need to study the influence of military environments on psychological development in a more systematic way in Brazil.

Topplistan som motivationsfaktor / The highscore list as motivational factor

Bergeling, Rickard, Forsberg, Erik January 2015 (has links)
Väldesignade spel är naturligt motiverande för att hålla kvar sina spelare. För att ett spel ska bli framgångsrikt är det viktigt att det innehåller motivationsförstärkare. På senare år har element hämtade från speldesign även använts inom andra områden, utanför sin vanliga kontext. Detta sammanfattas i begreppet gamification (sv. spelifiering).  Syftet med vår studie var att undersöka hur gamification kan påverka användandet av en applikation som är skapad i syfte att uppmuntra en miljövänlig livsstil. Detta gjorde vi genom att låta två testgrupper med studenter från programmet för Medieteknik vid Kungliga Tekniska Högskolan använda varsin applikation under åtta dagar. Applikationerna var identiska sånär som på en komponent: en av dem innehöll en topplista, vilket är en vanlig motivationsförstärkare inom speldesign. Utöver de data som vi samlade in genom applikationerna så lät vi även användarna svara på ett antal enkäter för att få kvalitativa svar angående deras användning av applikationen.  Resultaten visar att topplistan inte har fungerat som en motivationsförstärkare i det här fallet, men att många användare funnit motivation i att se sin personliga statistik. Införandet av topplistan krävde också att vi införde ett underliggande poängsystem. I diskussionen och analysen för vi resonemang om möjliga orsaker till undersökningens utfall. En möjlig förklaring till varför topplistan inte har höjt användarnas motivation kan vara poängsystemets utformning. Vidare visar resultatet att användare från olika årskurser visat på varierad motivation att använda applikationen. Studenter i årskurs ett och två har generellt presterat bättre än studenter i högre årskurser. / Well-designed games are naturally motivational to keep the players interested. For a game to be successful, it has to contain motivators. Recent years have seen elements from games used in other areas, out of their normal context. This is what is called gamification.  The purpose of our study is to examine how we can use common gamification elements to motivate our users to be more environmentally friendly. We have done this by letting two groups of students from the Programme of Media Technology at The Royal Institute of Technology use two separate applications. The study lasted for eight days and the two applications were identical except for one component – one of them contained a leaderboard, which is a common motivator in game design. We can see from our results that the leaderboard has not motivated our participants to be more considerate of the environment. A lot of people did however find motivation in their personal statistics. The use of a leaderboard required us to also implement an underlying points-system, one explanation to our outcome could be how this system was designed.

The technology learning area as a catalyst of creativity in foundation phase learners

Thatcher, Colleen Barbara 11 1900 (has links)
This study on technology in the South African school curriculum investigates the nature and value of this subject as a catalyst in developing Foundation Phase learners’ creative thinking skills Technology as school subject is defined as the use of knowledge, skills and available resources to develop solutions to meet human needs and wants, taking social and environmental factors into account. Central to this subject, is the design process of investigating, designing, making, evaluating and communicating solutions to problems identified in the environment. The notion and nature of creativity as researched by respected psychologists and researchers over the last few decades, with particular reference to Matlin’s theory of problem-solving and creativity, provides a theoretical underpinning with the aim of linking the problem-solving nature of technology with creative thinking. A qualitative case study research project, comprising a sample of six Foundation Phase learners at an independent school, has been conducted. Key characteristics of qualitative educational research such as sensitivity, precision, verification, empiricism, natural setting, inductive data analysis, validity and reliability and triangulation, have been taken into consideration. This study highlights the potential of technology as a school subject that provides learners with the opportunity to solve problems in creative ways and use authentic contexts rooted in real life situations. In addition, learners are afforded the opportunity to work collaboratively with others and engage in meaningful activities in the indoor and outdoor environment. Technology as a school subject in the Foundation Phase catalyzes learners’ creative thinking and problem-solving skills and provides a solid foundation for preparing young citizens for the demands and challenges of the 21st century. / Curriculum and Instructional Studies / D.

Disruptive Transformations in Health Care: Technological Innovation and the Acute Care General Hospital

Lucas, D. Pulane 24 April 2013 (has links)
Advances in medical technology have altered the need for certain types of surgery to be performed in traditional inpatient hospital settings. Less invasive surgical procedures allow a growing number of medical treatments to take place on an outpatient basis. Hospitals face growing competition from ambulatory surgery centers (ASCs). The competitive threats posed by ASCs are important, given that inpatient surgery has been the cornerstone of hospital services for over a century. Additional research is needed to understand how surgical volume shifts between and within acute care general hospitals (ACGHs) and ASCs. This study investigates how medical technology within the hospital industry is changing medical services delivery. The main purposes of this study are to (1) test Clayton M. Christensen’s theory of disruptive innovation in health care, and (2) examine the effects of disruptive innovation on appendectomy, cholecystectomy, and bariatric surgery (ACBS) utilization. Disruptive innovation theory contends that advanced technology combined with innovative business models—located outside of traditional product markets or delivery systems—will produce simplified, quality products and services at lower costs with broader accessibility. Consequently, new markets will emerge, and conventional industry leaders will experience a loss of market share to “non-traditional” new entrants into the marketplace. The underlying assumption of this work is that ASCs (innovative business models) have adopted laparoscopy (innovative technology) and their unification has initiated disruptive innovation within the hospital industry. The disruptive effects have spawned shifts in surgical volumes from open to laparoscopic procedures, from inpatient to ambulatory settings, and from hospitals to ASCs. The research hypothesizes that: (1) there will be larger increases in the percentage of laparoscopic ACBS performed than open ACBS procedures; (2) ambulatory ACBS will experience larger percent increases than inpatient ACBS procedures; and (3) ASCs will experience larger percent increases than ACGHs. The study tracks the utilization of open, laparoscopic, inpatient and ambulatory ACBS. The research questions that guide the inquiry are: 1. How has ACBS utilization changed over this time? 2. Do ACGHs and ASCs differ in the utilization of ACBS? 3. How do states differ in the utilization of ACBS? 4. Do study findings support disruptive innovation theory in the hospital industry? The quantitative study employs a panel design using hospital discharge data from 2004 and 2009. The unit of analysis is the facility. The sampling frame is comprised of ACGHs and ASCs in Florida and Wisconsin. The study employs exploratory and confirmatory data analysis. This work finds that disruptive innovation theory is an effective model for assessing the hospital industry. The model provides a useful framework for analyzing the interplay between ACGHs and ASCs. While study findings did not support the stated hypotheses, the impact of government interventions into the competitive marketplace supports the claims of disruptive innovation theory. Regulations that intervened in the hospital industry facilitated interactions between ASCs and ACGHs, reducing the number of ASCs performing ACBS and altering the trajectory of ACBS volume by shifting surgeries from ASCs to ACGHs.
