This study investigates the factors affecting the availability of health insurance, the accessibility of health care, and the dissemination of the relevant information among low‐wage Chinese immigrants in Southern California by relying on the concepts of social and cultural capital. Using community‐based research and in‐depth interviews, our study suggests that a severe shortage in health care coverage among low‐wage Chinese immigrants is influenced by the lack of employment with employer‐provided health insurance within the Chinese “ethnoburb” community. Although the valuable social capital generated by Chinese immigrant networks seems to be sufficient enough to provide them with certain practical resources, the lack of cultural capital renders the social network rather ineffective in providing critical health care information from mainstream American society.  相似文献

One important aspect of the German corporate tax reform 2008/2009 is the introduction of an EBITDA-based interest deduction limitation. This article focuses on the questions how many and which companies are threatened by this so-called “interest ceiling rule”. Based on an analysis of 77.464 financial statements of German corporations this limitation is relevant for 561 up to 1.511 companies. Thus, this thin-capitalization rule affects more companies than expected by politics. Additionally, we derived several hypotheses from theory concerning possible distortions caused by this rule and tested them empirically. As a result, the “interest ceiling” does affect systematically large, less profitable companies, those with high collaterals as well as holding and real estate companies. Consequently, domestic corporate decisions will be distorted and the theorem of production efficiency is violated.  相似文献

Abstract

“When to Perform Biopsies of Enlarged Peripheral Lymph Nodes in Young Patients,” GAIL B. SLAP, et al. Identification of young patients with peripheral lymphadenopathy who will benefit from lymph node biopsy often is difficult. A model was developed to differentiate patients whose biopsy results do not lead to treatment (normal, hyperplastic, or benign inflammatory lymph nodes) from those whose biopsy results do lead to treatment (granulomatous or malignant nodes). The medical records and histopathology slides of 123 nine- to 25-year-old patients who underwent biopsies of enlarged peripheral lymph nodes were reviewed for pathological diagnosis and 22 clinical findings. Seventy-two (58%) patients had biopsy results that did not lead to treatment, and 51 (42%) had results that did lead to treatment. Using stepwise discriminant analysis, a predictive model was developed that assigned 95% of the cases to the correct biopsy group based on lymph node size; history of recent ear, nose, and throat symptoms; and chest roentgenogram. When tested prospectively on new patients, the model correctly classified 32 (97%) of 33. We conclude that this simple model can help select adolescents and young adults with peripheral lymphadenopathy for biopsy. (Journal of the American Medical Association 1984;252:1321-1326.)

“The Clinical Information Value of the Glycosylated Hemoglobin Assay,” David M. Nathan, et al. We evaluated the clinical information value of the glycosylated hemoglobin assay by comparing it with practitioners' estimates of glucose control over the preceding 10 weeks in 216 patients with diabetes. Twenty-four percent of the practitioners' estimates, which were based on historical and laboratory data collected during a routine office visit, differed by more than ± 75 mg per deciliter from the actual mean blood glucose levels calculated with the glycosylated hemoglobin assay. One third of the mean blood glucose concentration fell outside the confidence intervals physicians used to bound their estimates. When examined individually or in the aggregate, historical information, such as polyuria, nocturia, or home urine testing for glucose, and laboratory information, such as fasting or random blood glucose levels, were weak predictors of the actual mean concentration of blood glucose.  相似文献

Previous studies have demonstrated that mentoring provides numerous career benefits to individuals and organizations. This article advances past work by examining the effects of individuals’ primary and multiple developmental relationships in a longitudinal study of the careers of lawyers. We develop a social capital perspective on mentorship emphasizing reciprocity of exchange, resource mobilization, and normative expectations embedded within mentoring relationships. We empirically assess mentoring benefits across a diverse range of career rewards. The results provide evidence that male lawyers gain more from their mentor‐derived social capital than female lawyers. Specifically, male lawyers with mentors of senior status benefit with elevated earnings, greater perceived fairness in their workplace, and greater work satisfaction. Women with multiple mentors, however, report enhanced work satisfaction. Implications for research on mentoring, social capital, and professional careers are discussed.  相似文献

Within lesbian, gay, bisexual and transgender (LGBT) research there is increasing health-related scholarship on trans lives, with a growing awareness of the impact of health inequalities on trans well-being. The aim of the paper is to provide greater understanding of transgender young people’s views of what is needed to promote their emotional well-being and resilience by undertaking specific analysis of data collected as part of wider research with young people (n?=?97). The study utilised participatory qualitative methods with a cross sectional design generating data via a focus group with trans youth (n?=?5), followed by thematic analysis. Findings suggest that both individual and collective capacities or resources enable and sustain resilience and well-being for trans young people. The adversity trans youth face is present in school, the community and in healthcare, but they are able to find places where they feel safe and connected to others. Practitioners, teachers and school nurses are well positioned to facilitate structural change in alliance with trans youth to promote resilience. Research results were utilised to inform health improvement, commissioning and service delivery.  相似文献

Understanding women’s attitudes toward retirement is crucial for being able to help women adjust to this transition. The present study uses interviews and questionnaires to understand retirement ambivalence and the role that close relationships play in women’s retirement experiences. Findings indicate that women have mixed feelings about retirement; they are both excited and fearful. They particularly enjoy the freedom and control this transition brings but are also moderately fearful of retirement, especially about shifting relationships. A better-quality relationship correlates with greater satisfaction and less fear. Such insights can be used to help women prepare for this major transition.  相似文献

Occupational hazards exist, if the design of the work situation is not in accordance with ergonomic design principles. At assembly lines ergonomics is applied to the design of work equipment and tasks and to work organisation. The ignoring of ergonomic principles in planning and design of assembly work leads to unfavourable working posture, action force and material handling. Disorders of the musculoskeletal system are of a common occurrence throughout Europe. Musculoskeletal disorders are a challenge against the background of disabled workers. The changes in a worker's capability have to be regarded in the conception of redesigned and new assembly lines. In this way ergonomics becomes progressively more important in planning and design of vehicles: The objective of ergonomic design in different stages of the vehicles development process is to achieve an optimal adaptation of the assembly work to workers. Hence the ergonomic screening tool "Design Check" (DC) was developed to identify ergonomic deficits in workplace layouts. The screening-tool is based on the current ergonomic state of the art in the design of physical work and relevant EU legal requirements. It was tested within a federal German research project at selected work stations at the assembly lines at Dr.-Ing. h.c. F. Porsche AG / Stuttgart. Meanwhile the application of the screening-tool DC is transferred in other parts of the Porsche AG, Stuttgart. It is also realized as an ergonomic standard method to perform assembly work in different phases of the vehicle development process.  相似文献

Although relationship distress is common, couples often forego professional help due to concerns such as time constraints, financial costs, and stigma. The two‐session relationship checkup is an alternative format of couple intervention developed to address these concerns. In this qualitative study, we interviewed 20 coupled participants and six clinicians to examine the checkup's processes and outcomes. The phenomenological themes that emerged revealed sequential processes by which this format works. Couple themes included client motivation, the therapeutic relationship, and therapeutic change in terms of perceptions and behaviors—particularly with regard to communication. Clinician data largely mirrored these themes. The results suggest the intervention addressed barriers to help‐seeking and may be a viable selective option for at‐risk couples.  相似文献

Attachment in adult romantic relationships has long been linked to conflict styles. Psychophysiological measures have provided additional insight into this association by accessing less conscious and controlled responses to conflict. The aim of this study was to explore the relationship between attachment anxiety, attachment avoidance, and the interaction between attachment styles on skin conductance responses during conflict and recovery from conflict. Using dyadic analysis of 50 heterosexual couples, we found evidence of a systemic effect of attachment, where psychophysiological arousal increased when one partner had higher levels of attachment anxiety and the other partner had higher levels of attachment avoidance. Attachment avoidance was also negatively associated with increased levels of arousal. Relationship and clinical implications of these findings are discussed.  相似文献

The professed aim of any social welfare or legal intervention in family life is often to bring about “better outcomes for the children.” But there is considerable ambiguity about “outcomes,” and the term is far too often used in far too simplistic a way. This paper draws on empirical research into the outcomes of care proceedings for a randomly selected sample of 616 children in England and Wales, about half starting proceedings in 2009–2010 and the others in 2014–2015. The paper considers the challenges of achieving and assessing “good outcomes” for the children. Outcomes are complex and fluid for all children, whatever the court order. One has to assess the progress of the children in the light of their individual needs and in the context of “normal” child development, and in terms of the legal provisions and policy expectations. A core paradox is that some of the most uncertain outcomes are for children who remain with or return to their parents; yet law and policy require that first consideration is given to this option. Greater transparency about the uncertainty of outcomes is a necessary step towards better understanding the risks and potential benefits of care proceedings.  相似文献
