We show that the large gender earnings gap at the top of the distribution (the glass ceiling) and the motherhood penalty are associated with each other and that both are uniquely associated with performance pay. These patterns appear consistent with specialization by gender. We show that among married couples with children, the hours worked by wives are strongly and persistently negatively correlated with earnings of the husbands only when those husbands work in performance pay jobs. There is no correlation between husbands’ hours and wives’ earnings.  相似文献

Background: The majority of people with dementia are cared for by their families at home. This study aimed to elicit family carers' perceptions on home environmental aspects and strategies with the view to identify barriers and facilitators when caring for a person with dementia at home.

Design and methods: Thirteen co-resident family carers were engaged in semi-structured in-depth walking interviews. Interviews were recorded, transcribed and analysed using thematic analysis.

Results: Home environments can pose a number of challenges and opportunities. Aspects of the architectural and interior environment (e.g. size, condition, layout and accessibility, familiarity) are perceived as important (Theme 1) as well as a plethora of environmental strategies that encourage independence and comfort at home (Theme 2). Carers' scepticism, timing, costs, property characteristics and mistrust to services are some barriers to implementing environmental strategies (Theme 3).

Conclusions: Carers improvised solutions via trial and error and need further education on strategies to create an enabling and comfortable home environment.  相似文献

In this article, we examine birth cohort differences in parents’ provision of monetary help to adult children with particular focus on the extent to which cohort differences in family structure and the transition to adulthood influence these changes. Using data from the Health and Retirement Study from 1994 to 2010, we compare financial help to children of three respondent cohorts as the parents in these birth cohorts from ages 53–58 to 57–62. We find that transfers to children have increased among more recent cohorts. Two trends—declining family size and children’s delay in marriage—account for part of the increase across cohorts. However, other trends, such as the increase in the number of stepchildren and increasing child’s income level, tend to decrease the observed cohort trend.  相似文献

In this position paper, I argue that the main purpose of research is to discover and report on phenomena in a truthful manner. Once uncovered, these phenomena can have important implications for society. The utility of research depends on whether it makes a contribution because it is original or can add to cumulative research efforts, is rigorously and reliably done, and is able to inform basic or applied research and later policy. However, five serious “diseases” stifle the production of useful research. These diseases include: significosis, an inordinate focus on statistically significant results; neophilia, an excessive appreciation for novelty; theorrhea, a mania for new theory; arigorium, a deficiency of rigor in theoretical and empirical work; and finally, disjunctivitis, a proclivity to produce large quantities of redundant, trivial, and incoherent works. I surmise that these diseases have caused immense harm to science and have cast doubt on the role of science in society. I discuss what publication gatekeepers should do to eradicate these diseases, to stimulate the undertaking of more useful and impactful research, and to provide the needed incentives to better align the interests of researchers with those of the greater good. Finally, I highlight where technical improvements are needed to enhance research quality, and call on deeper reflection, transparency, and honesty in how we do research.  相似文献

ABSTRACT

Applying the science of human factors to eliminate error across all aspects of process design, management, operation, and maintenance has been a focus in the process safety area for many years. Human error has been attributed as a major cause of many high profile catastrophic accidents around the world. These accidents have resulted in national and international attention, which has led to a focus on improving organizational capabilities, systems, and in many cases, governmental regulations around human factors. This article provides a review of the field of human factors highlighting various topics in the literature, and introduces governmental regulatory bodies currently engaging organizations in a scientific approach to human factors. Finally, the need for integrating behavioral science methodologies with human factors is addressed. This is done with specific focus on how Organizational Behavior Management methodologies can work in concert with human factors to optimize process safety.  相似文献

ABSTRACT

A recent prevalence of high visibility catastrophic events has garnered increased attention to process safety issues. While the use of Behavior-Based Safety interventions demonstrate a reduction in workplace injuries by targeting employee behavior, we believe that process safety requires a greater focus on the behavior of leaders (e.g., creating and executing strategy). One effective method to begin targeting leader behavior for the improvement of process safety is to teach leaders about the principles of behavior, including ways by which the science may be applied within their own organizational models.  相似文献

Child protection and welfare have become international issues in a globalized world. Ideas about childhood and the upbringing of children vary widely, depending upon the prevailing economic, socio-cultural, religious, and political contexts. These have had dramatic effects on the way societies value children, and the role acquired by the state in their protection and advancing their well-being. Children, however, remain at risk. They are placed at risk by the breakdown of extended family systems as a result of urbanization, and as a result of impaired functioning of some nuclear families, in the absence of kinship safety nets. Some traditional cultural practices place children at risk, especially girl children. Poverty creates risks for all children but it can create specific catastrophic risks for girls. Countries can enact visionary laws intended to protect children, but they will be ineffective against entrenched social attitudes, especially if only limited resources can be provided to implement and enforce them. This is the ultimate challenge that the world community must address if the vision of the United Nations Convention on the Rights of the Child is to be realized.  相似文献

This article examines the determinants of household gambling expenditures in Ireland and the effects of the recession on these expenditures using a large micro data-set, the Irish Household Budget Survey (HBS). Two gambling expenditures are examined, bookmaker tote betting and spending on the national lottery. Households with an older and a less educated head of household participate in and spend more on both forms of gambling while the presence of children in the households tends to reduce participation and spending in gambling. There is also evidence to suggest that households with an unemployed head of household have a higher likelihood of participation in gambling. The recession has affected the two forms of gambling in different ways. Lottery expenditures appear resilient to the effects of the recession. This is demonstrated in the estimated expenditure elasticities in particular. Bookmaker/tote expenditures have changed from a necessity to a luxury good, while lottery expenditures have increased in their necessity status. This can be explained by the fact that playing the lottery requires less time, knowledge and risk and has potentially greater benefits attached to it in comparison to bookmaker/tote betting. During a recession these factors become much more prevalent.  相似文献
