The working activity in traffic of the big cities complex interacts with the environment is often in unsafe and unhealthy imbalance favoring the binomial work - health. The aim of this paper was to analyze the relationship between work and health of taxi drivers in Curitiba, Brazil. This cross-sectional observational study with 206 individuals used a questionnaire on the organization's profile and perception of the environment and direct observation of work. It was found that the majority are male, aged between 26 and 49 years and has a high school degree. They are sedentary, like making a journey from 8 to 12 hours. They consider a stressful profession, related low back pain and are concerned about safety and accidents. 40% are smokers and consume alcoholic drink and 65% do not have or do not use devices of comfort. Risk factors present in the daily taxi constraints cause physical, cognitive and organizational and can affect your performance. It is concluded that the taxi drivers must change the unhealthy lifestyle, requiring a more efficient management of government authorities for this work is healthy and safe for all involved. 相似文献

We evaluated the effects of long-term testosterone replacement therapy (TRT) on the bone mineral density (BMD) in obese patients with metabolic syndrome (MS) and late-onset hypogonadism (LOH). Sixty men (mean age 57 ± 10) with low serum testosterone (T < 320 ng/dL) and MS regardless the presence of osteoporosis were enrolled. Forty men received intramuscular T-undecanoate (TU) four times/year for 36 months and 20 age-matched hypogonadal men with MS in whom T treatment was contraindicated were used as controls. Hormonal, biochemical markers, vertebral and femoral BMD by dual-energy x-ray absorptiometry were measured. At baseline, overall patients had mild osteopenia (lumbar BMD= 0.891 ± 0.097 g/cm(2); femoral BMD= 0.847 ± 0.117 g/cm(2)). TU induced a significant improvement of bone mass after 36 months (lumbar BMD=1.053 ± 0.145 g/cm(2); p < 0.002; femoral BMD=0.989 ± 0.109; p < 0.003 g/cm(2)) with a 5%/year increase and a significant reduction in hs-CRP without changes in body mass index. A direct relationship between serum T and BMD increments at the lumbar (r(2)?= 0.66, p < 0.0001) and femoral (r(2)?=0.52, p < 0.0001) sites was demonstrated. Study adherence was 50% without serious side effects. Long-term TRT in middle-aged men with LOH and MS determines a significant increase in both vertebral and femoral BMD related to increased serum T levels, probably independently from estradiol modifications. 相似文献

Older women often experience pain in their daily lives. This article provides an overview of topics addressed in the geriatric pain research published between 1999 and 2004. New areas of emphasis of research have emerged such as the recognition of body mass and weight as a factor in persistent pain, while other areas have expanded, including the focus on pain among elders with cognitive impairments and the use of alternative treatment approaches. Understanding of pain in late life is hindered by study samples that lack diversity, treatment approaches that are narrowly focused, and a lack of attention to quality of life issues. 相似文献

We propose a new principle of ‘non-interference’ applied to social welfare orderings. The principle, together with two other
standard requirements, implies a strong egalitarian conclusion: the ordering must lexicographically maximize the welfare of
the worst off.

A growing literature has examined the prevalence of transnational engagement among children of immigrants. However, few studies have been equipped to analyse underlying dynamics that serve to impede or perpetuate transnational practices among them in the United States. In this article, we compare transnationalism narratives between 1.5- and second-generation children of immigrants to more fully adjudicate enduring transnational ties over time. Our analysis of 134 interviews from the Children of Immigrants Longitudinal Study suggests that children of immigrants from Southern California conceptualise transnational experiences in diverse but remarkably similar ways. The meanings attached to transnational behaviours and identities employ certain patterns, and are often related to strength of kin-based ties, ethnic language fluency, and levels of structural access to the homeland. Moreover, findings indicate that the second-generation is nearly as transnationally engaged as the 1.5-generation. This provides novel but limited evidence in support of claims that transnational ties are sustained across generations. 相似文献

Unauthorized Status and Youth Development in the United States: Consensus Statement of the Society for Research on Adolescence 下载免费PDF全文
Hirokazu Yoshikawa Carola Suárez‐Orozco Roberto G. Gonzales 《Journal of research on adolescence》2017,27(1):4-19
In the United States, 5.3 million children and adolescents are growing up either with unauthorized status or with at least one parent who has that status. Until recently, little in the way of research has informed federal, state, and local policy debates related to unauthorized status (e.g., border enforcement, deportation, and a pathway to citizenship) although these issues have important implications for youth development. This statement is a brief summary of the research evidence on multiple domains of development that may be affected by the child or parent's unauthorized status. We also describe the contextual and psychological mechanisms that may link this status to developmental outcomes. We summarize a range of policies and practices that could reduce the developmental harm to children, youth, and their families stemming from this status. Finally, we conclude with recommendations for policy, practice, and research that are based on the evidence reviewed. 相似文献

Since ERASMUS (European Region Action Scheme for the Mobility of University Students) was launched there has been a constant debate about the civic significance of this mobility programme. The purpose of this article is to analyse the understanding of active citizenship by Erasmus students. In order to discover Erasmus students’ perceptions, values, beliefs and attitudes regarding the issue under discussion, original data were collected from 174 students who participated in our survey in March 2014. By applying a statistical analysis, the most and the least important criteria for being considered an active citizen have been extracted from the answers of our respondents. In addition, we studied their attitudes towards and knowledge of the European Union (EU). We found that their understanding of ‘active citizenship’ echoes with the definition of the concept provided in the research literature. 相似文献

At the heart of this article is a structural approach to narrative, based on the work of Propp, Labov, van Dijk, Halliday,
and others. The article highlights the structural features of narrative—basically, the organization of the genre around the
semantic template actor-action-actor (syntactically rendered as subject-verb-object but where, in narrative, the subject is
typically a social actor and the verb a social action) and the modifiers of each element of this triplet, such as time and
space of action—and shows how to implement this structure in a computer environment and how to use this methodological tool
in socio-historical research (namely, the rise of Italian fascism, 1919–22). But, taking a cue from Halliday’s cover jacket
of his An Introduction to Functional Grammar, with its representation of a color circle, the paper takes the reader on an intellectual journey from Newton to Goethe—and
the quality versus quantity debate—to Goethe and Propp, to end, back home, with Simmel and Weber. 相似文献

We introduce a point source model which may be useful for estimating point sources in spatial data. It may also be useful for modelling general spatial data, and providing a simple explanatory model for some data, whilst in other cases it may give a parsimonious representation. The model assumes that there are point sources (or sinks), usually at unknown positions, and that the mean value at a site depends on the distance from these sources. We discuss the general form of the model, and some methods for estimating the sources and the regression parameters. We demonstrate the methodology using a simulation study, and apply the model to two real data sets. Some possibilities for further research are outlined. 相似文献

Data from Virginia Adult Protective Services (APS) case files of 95 abused women aged 60 years and older were assessed to establish demographic trends; ability to care for self; type, pattern, and place of abuse; information on witnesses and alleged offenders; and case resolution and outcomes. The most common types of mistreatment reported were neglect, exploitation, and physical abuse. The women typically had several functional limitations and were dependent upon their family members for care. Most cases were not prosecuted, and the majority of women remain at risk for further abuse. Implications of these data for future research and practice are discussed. 相似文献
