The aim of this paper is to find an empirical connection between the striking increase in the use of fixed-term contracts in Spain and the observed delay in the age at marriage and maternity. Using the eight waves of individual information from the European Household Panel for Spain, we find that for men, the decision whether to get married is strongly negatively affected by holding unstable contracts or not working, relative to when an indefinite contract is held. However, for women, results suggest that holding fixed-term contracts is not a deterrent for the decision whether to get married. With respect to the decision of whether to enter into parenthood, results indicate that for all childless women, either with no partner, holding fixed-term contracts delays entry into motherhood relative to the holding of indefinite contracts. The discouragement effect is stronger for women with no partner, though.JEL classification: D1, J1 相似文献

AbstractObjective: To examine changes in diagnoses/treatment for 12 mental health (MH) conditions, previous use of campus MH services, and willingness to seek MH services in the future. Participants: ACHA–NCHA II participants from 2009 to 2015 (n?=?454,029). Methods: Hierarchical binary logistic regression with step 1 controlling for demographics and step 2 considering time. Results: Time was significant except for bipolar disorder, bulimia, and schizophrenia with increases for all conditions except substance abuse. Anxiety (OR?=?1.68), panic attacks (OR?=?1.61), and ADHD (OR?=?1.40) had the highest odd ratios. Use of MH services at current institution (OR?=?1.30) and willingness to utilize services in the future (OR?=?1.37) also increased over time. Conclusions: Based on a national sample, self-reported diagnoses/treatment of several MH conditions are increasing among college students. This examination of a variety of MH issues can aid college health professionals to engage institutional stakeholders regarding the resources needed to support college students’ MH. 相似文献

Over the last 5 years, environmental justice (EJ) researchers have been calling for incorporation of health outcomes more
directly into spatial studies of socio-demographics and environmental hazards. To date, researchers have not incorporated
insurance status (an access to health care variable) in their models although access to care likely has an important association
with the probability of health effects due to environmental exposures. As such, insurance status represents an important variable
within spatial EJ studies focused on health, and the lack of spatially explicit access to care data is a critical limitation
in the field. As a solution, we offer a method of using uninsured appendicitis cases, acquired secondarily from state hospital
admissions data, to estimate rates of uninsurance at the zip-code level. We apply the technique to explore relationships between
cancer risk from hazardous air pollutants and estimated rates of uninsurance, a previously unexplored phenomenon. Then, we
compare the uninsurance findings to those related to poverty to illustrate how uninsurance, as a variable, compares to a more
traditional socio-economic predictor used in EJ studies. The relationship between cancer risk from hazardous air pollutants
and uninsurance is weaker than the relationship between risk and poverty, but both are statistically significant. As such,
we conclude with a discussion of the importance of considering insurance status in spatial studies of EJ focused on health. 相似文献

The aim was to identify the proportion of fathers having a positive experience of a normal birth and to explore factors related to midwifery care that were associated with a positive experience.
Background
Research has mainly focused on the father's supportive role during childbirth rather than his personal experiences of birth.Methods
595 new fathers living in a northern part of Sweden, whose partner had a normal birth, were included in the study. Data was collected by questionnaires. Odds Ratios with 95% confidence interval and logistic regression analysis were used.Results
The majority of fathers (82%) reported a positive birth experience. The strongest factors associated with a positive birth experience were midwife support (OR 4.0; 95 CI 2.0–8.1), the midwife's ongoing presence in the delivery room (OR 2.0; 1.1–3.9), and information about the progress of labour (OR 3.1; 1.6–5.8).Conclusion
Most fathers had a positive birth experience. Midwifery support, the midwife's presence and sufficient information about the progress of labour are important aspects in a father's positive birth experience. The role of the midwife during birth is important to the father, and his individual needs should be considered in order to enhance a positive birth experience. 相似文献85.
Throughout the past 70 years, a great deal of research conducted on defining and testing problem-solving skills has led toward solution-focused practices and philosophies. As a result, some literature exists illustrating the efficacy of solution-focused practices. However, no published research exists on the factors that contribute to solution building. This study tested for components of solution building while creating a solution building inventory. Results from a factor analysis failed to find specific factors within solution building; thus solution building appears to be a unidimensional concept. Implications for using the solution building inventory are discussed. 相似文献

For more than a decade, casinos around the world have offered self-exclusion programs (SEPs) to gamblers seeking help with
their gambling behavior. Despite the proliferation of SEPs, little is known about the long-term outcomes for gamblers who
utilize these programs. The current study assessed the experiences of a sample (N = 113) of Missouri self-excluders (SEs) for as long as 10 years after their initial enrollment in the Missouri Voluntary
Exclusion Program (MVEP). Most SEs had positive experiences with MVEP and reduced their gambling and gambling problems after
enrollment. However, 50% of SEs who attempted to trespass at Missouri casinos after enrollment were able to, indicating that
the benefit of MVEP was attributable more to the act of enrollment than enforcement. SEs who engaged in complementary treatment
or self-help groups had more positive outcomes than those who did not, suggesting that SEPs ought to encourage and provide
information about additional support and treatment options to participants. 相似文献

Evolution of the Debate on Control Enhancing Mechanisms: A Systematic Review and Bibliometric Analysis 下载免费PDF全文
This paper aims to assess the state of the art, the structure and the evolution of the debate on control enhancing mechanisms (hereafter CEMs). It combines bibliometric and qualitative methodologies to analyze 210 articles published in scientific journals up to 2014. The findings show that the academics’ interest has increased over time, and the research has simultaneously developed along two main poles: antecedents and consequences of the proportionality principle. The analyses also reveal that the debate stems from the US studies on the legal principles of disproportionate ownership devices at the end of 19th century, and has been strongly fueled by the ‘law and finance’ theorists. This paper has both theoretical and practical implications. First, it provides insights into underexplored issues where future research efforts could be focused. Second, it supports new policy‐making interventions to CEMs and encourages investor regulation and corporate transparency. 相似文献

A mail survey was conducted in order to investigate whether the importance a manager attaches to corporate ethical and legal responsibilities varies according to personality characteristics, demographic variables, or the perceived moral climates in the manager's firm. Respondents were middle- and lower-level managers in 112 for-profit businesses located throughout the United States. As expected, attitudes about corporate ethical responsibility were significantly related to (1) the individual's capacity for empathy and (2) a perceived caring climate in the firm; attitudes about corporate legal responsibility were significantly related to (1) the individual's hierarchical position and (2) an organizational climate perceived to be supportive of law.Data collection for this research was subsidized by the Old Dominion University Research Foundation and the ODU College of Business and Public Administration Bureau of Research. 相似文献
