Suburban lifestyle is popular among American families, although it has been criticized for encouraging automobile use through longer commutes, causing heavy traffic congestion, and destroying open spaces (Handy, 2005). It is a serious concern that people living in low-density suburban areas suffer from high automobile dependency and lower rates of daily physical activity, both of which result in social, environmental and health-related costs. In response to such concerns, researchers have investigated the inter-relationships between urban land-use pattern and travel behavior within the last few decades and suggested that land-use planning can play a significant role in changing travel behavior in the long-term. However, debates regarding the magnitude and efficiency of the effects of land-use on travel patterns have been contentious over the years. Changes in built-environment patterns is potentially considered a long-term panacea for automobile dependency and traffic congestion, despite some researchers arguing that the effects of land-use on travel behavior are minor, if any. It is still not clear why the estimated impact is different in urban areas and how effective a proposed land-use change/policy is in changing certain travel behavior. This knowledge gap has made it difficult for decision-makers to evaluate land-use plans and policies. In addition, little is known about the influence of the large-scale built environment. In the present dissertation, advanced spatial-statistical tools have been employed to better understand and analyze these impacts at different scales, along with analyzing transit-oriented development policy at both small and large scales. The objective of this research is to: (1) develop scalable and consistent measures of the overall physical form of metropolitan areas; (2) re-examine the effects of built-environment factors at different hierarchical scales on travel behavior, and, in particular, on vehicle miles traveled (VMT) and car ownership; and (3) investigate the effects of transit-oriented development on travel behavior. The findings show that changes in built-environment at both local and regional levels could be very influential in changing travel behavior. Specifically, the promotion of compact, mixed-use built environment with well-connected street networks reduces VMT and car ownership, resulting in less traffic congestion, air pollution, and energy consumption.

Numerous scholars have accumulated evidence on the positive effects that employees' organizational justice perceptions exert on work-related outcomes such as affective commitment. However, research still lacks understanding of the underlying mechanisms connecting the two constructs. In this article we aim to narrow this gap by examining the concept of psychological ownership as a possible mediator between organizational justice perceptions and affective commitment. Investigating a sample of 619 employees, we find distributive justice to be positively related to psychological ownership, and observe psychological ownership as a full mediator of the distributive justice and affective commitment relationship. These insights offer a new explanation in understanding the justice-commitment connection, contributing to both organizational justice and psychological ownership literature and opening up ways for promising future research

The purpose of this article is to investigate how ownership structure, especially family and/or venture-capital involvement, as well as entrepreneurial activities, defined as strategic change and renewal, help explain the involvement of independent members on boards of directors. The CEOs of 2,455 small and medium-sized, private enterprises from practically all industries were contacted in a telephone survey, resulting in an exceptionally high response rate. The findings reveal that family firms are more reluctant to involve independent directors on their boards than non-family firms that presence of venture capitalists increases the frequency of independent board members and that ownership has an impact on board roles. The results do not support the hypothesised relationship that independent directors enhance entrepreneurial activities. One implication of our study is that the often-argued-for strategic contribution of outsiders to the boards in family firms may be overemphasised. Another implication is that family firms that choose to acquire additional capital should be aware that this could result in a change in the board composition and the loss of control of the business. However, new and external owners’ inclusion on the board seems to be negotiable since there are also venture capitalists that do not insist on board representation.

The purpose of this work is to investigate the digital online- and website- presence of the international automobile industry. The focus is on the business-to-consumer area to find out how digital communication is designed and if there are differences in the design dependent on the type of company or its cultural origin. The research is based on different quantitative as well as qualitative studies. After the selection and validation of the test sample, a qualitative content analysis for each corporate website in the test sample is conducted. Then, an extensive quantitative content analysis is applied. In a third step interviews with nine different experts from different sectors of the automobile company are carried out to validate the previous findings and obtain deeper insights. All of the findings are statistically analyzed and comprehensively evaluated.

Big data are reshaping the way we interact with technology, thus fostering new applications to increase the safety-assessment of foods. An extraordinary amount of information is analysed using machine learning approaches aimed at detecting the existence or predicting the likelihood of future risks. Food business operators have to share the results of these analyses when applying to place on the market regulated products, whereas agri-food safety agencies (including the European Food Safety Authority) are exploring new avenues to increase the accuracy of their evaluations by processing Big data. Such an informational endowment brings with it opportunities and risks correlated to the extraction of meaningful inferences from data. However, conflicting interests and tensions among the involved entities - the industry, food safety agencies, and consumers - hinder the finding of shared methods to steer the processing of Big data in a sound, transparent and trustworthy way. A recent reform in the EU sectoral legislation, the lack of trust and the presence of a considerable number of stakeholders highlight the need of ethical contributions aimed at steering the development and the deployment of Big data applications. Moreover, Artificial Intelligence guidelines and charters published by European Union institutions and Member States have to be discussed in light of applied contexts, including the one at stake. This thesis aims to contribute to these goals by discussing what principles should be put forward when processing Big data in the context of agri-food safety-risk assessment. The research focuses on two interviewed topics - data ownership and data governance - by evaluating how the regulatory framework addresses the challenges raised by Big data analysis in these domains. The outcome of the project is a tentative Roadmap aimed to identify the principles to be observed when processing Big data in this domain and their possible implementations.

This aim of this work was to carry out an epidemiological study on acetabular fractures in the city of Campinas and surrounds, in view of the few published papers on this subject. Medical files with a diagnosis of acetabular fracture between the years 2004 and 2008 that were made available by the Medical Archiving Service of Hospital das Clínicas, State University of Campinas (UNICAMP) were analyzed by six observers. Data on patients' ages, sex, side affected by the fracture, mechanism of injury, material used for synthesis, complications of the operation, associated fractures, length of hospitalization before and after the surgery, time of total internment and number of physiotherapy sessions before and after the surgery were gathered. It was observed in this population that the left side was more affected; the mechanism of injury that most often caused this type of fracture was automobile accidents; injuries to the sciatic nerve were the commonest surgical complications; and the synthesis material most used was reconstruction plates.

O estudo avalia diferenças quanto às características sociodemográficas, de estilo de vida e de condições de saúde entre adultos com e sem linha telefônica residencial, valendo-se de dados de inquérito domiciliar de saúde realizado em Campinas, São Paulo, Brasil (2008/2009). Trata-se de estudo transversal de base populacional com 2.637 adultos (18 anos e mais). Análises descritivas, testes qui-quadrado, prevalências e respectivos intervalos de 95% de confiança foram calculados. Estimaram-se os vícios associados à não cobertura da população sem telefone antes e após o ajuste de pós-estratificação. O impacto do vício nos intervalos de confiança foi avaliado pela razão de vício. Cerca de 76% dos entrevistados possuíam linha telefônica residencial. Exceto para situação conjugal, foram observadas diferenças sociodemográficas segundo posse de telefone. Após o ajuste de pós-estratificação, houve redução do vício das estimativas para as variáveis associadas à posse de linha telefônica, no entanto, exceto para osteoporose, o ajuste de pós-estratificação foi insuficiente para corrigir o vício de não cobertura.

A utilização de serviços odontológicos resulta da interação de determinantes biológicos com fatores socioculturais, familiares e comunitários, bem como de características dos sistemas de saúde. O objetivo deste estudo foi identificar os fatores individuais associados à utilização de serviços odontológicos por parte de adultos e idosos de baixa renda residentes na área de abrangência da Estratégia Saúde da Família, em Ponta Grossa, PR. A amostra constou de 246 indivíduos, com 35 anos de idade ou mais, que responderam a um questionário sobre condições socioeconômicas, necessidade percebida e acesso a serviços odontológicos. A análise dos dados foi realizada por meio de regressão logística, segundo referencial teórico baseado no Modelo Comportamental de Andersen, considerando a consulta odontológica não recente como variável dependente. Verificou-se elevada prevalência de problemas bucais auto-referidos e de perdas dentárias. Cerca de 40% dos adultos e 67% dos idosos não iam ao dentista há mais de três anos. Indivíduos que não residiam em domicílios próprios, realizavam higiene bucal com menor frequência e utilizavam próteses totais apresentaram maiores chances de haver utilizado os serviços odontológicos há mais tempo. O fato de possuir um dentista regular foi identificado como fator de proteção na análise. Concluindo, os determinantes individuais mostraram-se importantes indicadores de acesso aos serviços de saúde bucal. O modelo teórico confirmou a presença de desigualdades sociais e psicossociais na utilização de serviços odontológicos entre os adultos e idosos de baixa renda.

The study objective was to evaluate the feasibility of interviews by cell phone as a complement to interviews by landline to estimate risk and protection factors for chronic non-communicable diseases. Adult cell phone users were evaluated by random digit dialing. Questions asked were: age, sex, education, race, marital status, ownership of landline and cell phones, health condition, weight and height, medical diagnosis of hypertension and diabetes, physical activity, diet, binge drinking and smoking. The estimates were calculated using post-stratification weights. The cell phone interview system showed a reduced capacity to reach elderly and low educated populations. The estimates of the risk and protection factors for chronic non-communicable diseases in cell phone interviews were equal to the estimates obtained by landline phone. Eligibility, success and refusal rates using the cell phone system were lower than those of the landline system, but loss and cost were much higher, suggesting it is unsatisfactory as a complementary method in such a context.

Os acidentes de trânsito no Brasil se constituem em relevante problema para a área da saúde. Nesse sentido, julgou-se importante investigar qual o efeito da lei 11.705 de 19 de junho de 2008, a chamada Lei seca. A metodologia do trabalho constitui analisar os dados do Sistema de Informações Hospitalares do SUS, para o Brasil, em 2008, comparando as internações nos dois semestres do ano, segundo algumas variáveis consideradas importantes. Os resultados mostraram que houve uma queda de 28,3 por cento nas internações do segundo semestre, com reflexos consideráveis em todas as variáveis estudadas. Quanto à qualidade da vítima, a maior queda ocorreu entre os ocupantes de automóvel, principalmente do sexo masculino. Em relação às idades, houve declínio em todas as faixas, destacando-se as de 40 a 59 anos e 20 a 39 anos, pela ordem. O tempo de permanência na instituição foi menor no segundo semestre,quando a mortalidade hospitalar declinou 13,6 por cento em relação ao primeiro semestre, o que significa que deixaram de morrer 917 pessoas (cerca de 5 mortes/dias). O gasto governamental para o atendimento dos feridos no segundo semestre foi 35,5 por cento menor do que no primeiro

Analisar diferenças quanto a características sociodemográficas e relacionadas à saúde entre indivíduos com e sem linha telefônica residencial. Foram analisados os dados do Inquérito de Saúde (ISA-Capital) 2003, um estudo transversal realizado em São Paulo, SP, no mesmo ano. Os moradores que possuíam linha telefônica residencial foram comparados com os que disseram não possuir linha telefônica, segundo as variáveis sociodemográficas, de estilo de vida, estado de saúde e utilização de serviços de saúde. Foram estimados os vícios associados à não-cobertura por parte da população sem telefone, verificando-se sua diminuição após a utilização de ajustes de pós-estratificação. Dos 1.878 entrevistados acima de 18 anos, 80,1% possuía linha telefônica residencial. Na comparação entre os grupos, as principais diferenças sociodemográficas entre indivíduos que não possuíam linha residencial foram: menor idade, maior proporção de indivíduos de raça/cor negra e parda, menor proporção de entrevistados casada, maior proporção de desempregados e com menor escolaridade. Os moradores sem linha telefônica residencial realizavam menos exames de saúde, fumavam e bebiam mais. Ainda, esse grupo consumiu menos medicamentos, auto-avaliou-se em piores condições de saúde e usou mais o Sistema Único de Saúde. Ao se excluir da análise a população sem telefone, as estimativas de consultas odontológicas, alcoolismo, consumo de medicamentos e utilização do SUS para realização de Papanicolaou foram as que tiveram maior vício. Após o ajuste de pós-estratificação, houve diminuição do vício das estimativas para as variáveis associadas à posse de linha telefônica residencial. ) A exclusão dos moradores sem linha telefônica é uma das principais limitações das pesquisas realizadas por esse meio. No entanto, a utilização de técnicas estatísticas de ajustes de pós-estratificação permite a diminuição dos vícios de não cobertura
