This paper investigates the effects of foreign workers on labor market outcomes for Palestinian workers in the Israeli labor
market. The paper utilizes a micro-dataset on the Palestinian labor force combined with time-series data on foreign workers
in Israel. The data covers the period 1999–2003, a period in which Israel enforced a strict closure on labor (and goods) movement,
particularly in 2001 and 2002. The evidence suggests that foreign workers in Israel do not affect Palestinian employment;
however, an increase in the number of foreign workers in Israel tends to reduce Israeli wages paid to Palestinian workers
from the Gaza Strip. The Israeli closure policy appears to be the main cause for the substantial reduction in long-run Palestinian
employment levels in Israel, not the presence of foreign workers. 相似文献

If voters vote strategically, is it useful to offer them the possibility of expressing nuanced opinions, or would they always overstate the intensity of their preferences? For additive voting rules, say that a ballot is extremal if it is neither abstention-like nor can be expressed as a mixture of the available ballots. We give a sufficient condition for strategic equivalence: if two rules share the same set of extremal ballots (up to an homothetic transformation), they are strategically equivalent in large elections. This condition is also necessary for the strategic equivalence of positional rules. These results do not hold for small electorates. 相似文献

This study examines the interactions between homeless pet owners and the domiciled public with a focus on how the activities of pet ownership help construct positive personal identities. Homeless people are often criticized for having pets. They counter these attacks using open and contained responses to stigmatization. More often, they redefine pet ownership to incorporate how they provide for their animals, challenging definitions that require a physical home. Homeless pet owners thus create a positive moral identity by emphasizing that they feed their animals first and give them freedom that the pets of the domiciled lack. Through what we call “enabled resistance,” donations of pet food from the supportive public provide the resources to minimize the impact of stigmatization. 相似文献

Fostering participant engagement is a challenging but essential component of effective prevention programs. To better understand which factors influence engagement, this study examines several predictors of couple engagement in Family Foundations (FF), a preventive intervention for first-time parents shown to enhance parent mental health, couple relations, parenting quality, and child adjustment through age 3 years. FF consists of a series of classes delivered through childbirth education departments at local hospitals. Baseline data on socio-demographics, parent mental health, and couple relationship quality were examined as predictors of participants’ level of engagement in FF (n = 89 couples, 178 individuals). Sociodemographic variables such as parent gender, socioeconomic status, and age predicted program engagement to a limited extent. However, findings indicated that marital status was the best predictor of engagement. Discussion focuses on how findings can inform the development of practices that promote engagement, such as the use of targeted outreach efforts for individuals most at risk of disengagement. 相似文献

Participants?? faces were covertly recorded while they rated the attractiveness of people, the decorative appeal of paintings, and the cuteness of animals. Ratings employed a continuous scale. The same participants then returned and tried to guess ratings from 3-s videotapes of themselves and other targets. Performance was above chance in all three stimulus categories, thereby replicating the results of an earlier study (North et al. in J Exp Soc Psychol 46(6):1109?C1113, 2010) but this time using a more sensitive rating procedure. Across conditions, accuracy in reading one??s own face was not reliably better than other-accuracy. We discuss our findings in the context of ??simulation?? theories of face-based emotion recognition (Goldman in The philosophy, psychology, and neuroscience of mindreading. Oxford University Press, Oxford, 2006) and the larger body of accuracy research. 相似文献

Through the analysis of qualitative data of the life stories of ten male returners to further education this article aims to support and develop some of the ideas presented in Gender, Work & Organization by both Simpson in 2005 and Lupton in 2006 on men in non‐traditional occupations. I employ the notion of multiple masculinities to understand my cohort's careers and demonstrate that over time early socialization can be overcome so that some men can make non‐stereotypical career decisions later in life. In offering an explanation as to why this might be the case, I argue that in late modernity some men can actively choose non‐traditional occupations, albeit within a gendered and classed labour market. I also offer insights into male identity in late modernity. 相似文献

Research has shown that lesbian and gay (LG) individuals are coming out not only to their parents, but also to their siblings. Eighty percent of individuals in the United States are raised with one or more siblings; however, researchers have frequently underestimated the importance of the sibling bond. This study examined potential correlates of heterosexual siblings’ acceptance of their LG sister or brother using an online survey format (N = 189). In addition, psychometric properties for the Acceptance of Sibling Sexual Orientation Scale are provided. Results revealed that greater sibling relationship quality in adulthood, more contact with LG individuals, greater knowledge of LG communities, more support for LG civil rights, and various demographics (being female, having higher educational levels, not having an orthodox/fundamentalist religious orientation, less church attendance, and more liberal political ideology) are related to heterosexual siblings’ acceptance of their LG sister or brother. However, when these variables were examined together in a regression model, only sibling relationship in adulthood, contact with LG individuals, support for LG civil rights, and religious attendance were significant unique predictors of acceptance. 相似文献

In order to implement preventive programs to prevent back pain in nurses, assessments of the degree of passivity and mobility of patients is imperative. After all, the load in health care ergonomics, is often the patient. The degree of cooperation or resistance determines the load on the back for the nurses and the necessity of the use of lifting devices like patient lifters or sliding sheets. These assessments must be done in both a practical and a reliable way. For this purpose a 3-category and a 5- category system to assess the degree of patient mobility and passivity was developed and tested. The results are presented on the poster. 相似文献

In hospitals many horizontal transfers (from stretcher to bed etc.) are performed from the moment a patient is admitted (f.e. with an ambulance) through examination departments all the way to the wards. These transfers can be very strenuous and solutions may be to use a special lifting device that accompanies the patient on this route: a stretcher sling This is a specially designed disposable lifting sling for horizontal transfers and repositioning, the sling can easily be connected to a ceiling or mobile lift. The ambulance service, two hospitals and a manufacturer decided to study the effects. The stretcher sling travels with the patient. Does this provide an ergonomically sound solution and is this an effective and efficient solution? The results were positive, but a behavioral change was also necessary. 相似文献

Packaging and labeling play a crucial role awhile protecting medicaments and transmitting a range of crucial information to the users. Taking into account the scarcity of specific studies in this area, it was considered great the need for a comprehensive survey about customers' satisfaction when handling these containers. 相似文献
