This paper uses a cohort of 12,000 births to examine the effect of maternity rights on mothers' post-birth return to employment decisions. It uses a discrete hazard model to disentangle the effects of the terms of maternity rights entitlements from other factors that influence the timing of a mother's return to work. Mothers with rights have an underlying (but unobserved) stronger attachment to the labour market that prompts earlier return than on average. We take this into account by estimating a counterfactual distribution of return times using a sample of women who failed to qualify for maternity rights but who have similar levels of labour market attachment. Even when differential attachment is taken into account there remains a substantial impact of maternity rights on behaviour.  相似文献

The value of involving students in research has been well documented. By including students in research, active and independent learning opportunities are provided, the importance of inquiry and investigation is emphasized, and connections between course material and the discipline become evident. Relevant opportunities for involving students in research projects can sometimes be elusive. Faculty time constraints limit the number of projects that can be undertaken and the number of students involved. Furthermore, many students become intimidated when told that they are required to carry out a research project. The purpose of this study was to use current consumer issues to involve undergraduate students in a relevant research project. The research project was implemented in class settings with teams of students. Faculty selected contemporary consumer issues based upon perceived student interest and experiences as consumers. By using issues of high relevance and familiarity to students and using the team approach within a course that faculty members were already assigned to teach, the issues of time constraint for the faculty members and increased levels of comfort for students were addressed. Prior to undertaking the project, students were instructed in appropriate research methods. Research methods utilized included student development of survey instruments, collection and recording of data, interpretation of data and presentation of results. Students became familiar with various research practices. By working as team members, the students’ comfort level for being involved in research increased; however, other common group challenges arose. Relevant, contemporary consumer issues carry high relevance and interest for student groups, helping generate enthusiasm for the research process. The focus on involving students in research continues to be emphasized. By using research topics related to student's experiences as consumers, students are more readily engaged in undertaking research projects. Through these relevant research projects, students’ consumer decision making is positively impacted.  相似文献

Reducing adolescent substance use is important in South Africa, a developing nation with increasing adolescent substance use, lack of leisure/recreation opportunities, and high rates of adolescent discretionary time. Previous research suggests leisure boredom and adolescent substance use co-occur in this setting. Using longitudinal data from 2,580 South African adolescents as they progressed from the 8th to 11th grade, the current study disentangles the associations of trait and state leisure boredom with substance use, and examines how ability to restructure boring situations moderates those associations. On average, individuals with higher trait boredom used more substances, and on occasions when state boredom was high, the prototypical adolescent used more substances. Although restructuring did not moderate these associations, greater ability was associated with lower substance use independent of leisure boredom. Findings illustrated the importance of considering how trait and state aspects of leisure may contribute to adolescents’ risk behavior and addressed through preventive intervention.  相似文献

In recent years, a growing number of small-to-medium-enterprises are embracing wind turbine projects not only as part of their cost reduction strategy but also to actively play their part in the global fight against climate change. However, it would appear there are currently limited empirical studies carried out in this emerging industry. This case study analyses the cost effectiveness of one such wind turbine initiative by a company in the Republic of Ireland, who invested in a 300 kW embedded wind turbine project at the end of 2013. The research methodology which is primarily a case study analysis included comparing historical electricity utility bills which allowed the 2013 quantity of electrical energy units imported, i.e. the year before the turbine was installed to be compared with the 2014 value, i.e. the year after the turbine was installed. Numerous site visits were undertaken over a four-year period, during which electric meter readings were recorded and stored. The findings of this piece of research indicate that the installation of the embedded wind turbine had minimal positive effect on the annual electricity costs for the company. Indeed the turbine appears to have significant negative effects such as a need for an increased maximum import capacity and also it appeared to contribute to a deteriorating utility power factor. While the aesthetic nature of the on-site turbine seemed to create a positive image of the company, it would appear that caution should be exercised when business owners select alternative energy providers who claim to be experts in the energy field but may have limited knowledge in this area of wind energy, which as of yet has minimal robust research into all aspects of its benefits/attributes.  相似文献

President Donald Trump espouses “America First” positions which are commonly interpreted as protectionist. However, a closer reading of Donald Trump’s business interests, of his administration’s published trade agenda and of US trade negotiation history calls into question whether “America First” means protectionism. Trump will use large trade deficits to pressure trading partners to further open up their markets. Companies that are successful in exporting to the US market from those countries will be alarmed by protectionist announcements and will therefore most likely pressure their governments to give in to the demands of the Trump administration.  相似文献

Using data for a one-year period from the Kingston Public Hospital (KPH) in Jamaica, we describe patterns of non-fatal violence-related injuries, and carry out simulation analysis to estimate rates of hospital admission under various injury reduction scenarios, and the potential savings that can be realized by reducing violent crimes. In this period there were 6107 registered violence-related visits to the KPH representing 11.5% of all recorded visits. Of these 16.6% (1001) were admitted. The most common methods of inflicting injury was by stabbing (52.1%), blunt injuries (37.9%) and gunshot wounds (7.3%). Multivariate analyses indicated that gunshot injuries, stab injuries, being male between the ages of 15 and 44 years, receiving the injury in November or December, and being injured by a stranger or unknown assailant, were significant correlates of a higher probability of admission. Simulation analysis with various injury reduction scenarios indicated decreases in the probability of admission ranging from 12% to 44%, with estimated savings of up to 31% of the annual supplies budget of KPH.  相似文献

The present research examines consumer behavior from a subjectivist perspective. In a phenomenological sense consumption consists of the generation of internal thoughts and|or sensations, which constitute the content of experience. The sociopsychological characteristics of consumers who primarily seek cognitive stimulation (cognition seekers), sensory stimulation (sensation seekers), novel stimulation (noveltry seekers), or are seekers of all three forms of experience (experience seekers) are delineated. Preliminary causal rationales for each type of consumption are put forward based on these findings.  相似文献

The current merging of computer and communications technologies is facilitating the trend towardtelework-remote work arrangements enabled by information technology. Organizations today have ever increasing options in the management and distribution of their work processes. In this study, we review the research on telework conducted in the United States, Western Europe, and Japan. We then propose a taxonomy for classifying different types of telework. Using this taxonomy, we examine the spatial, coordination, and temporal structures of different types of telework.Previous research results indicate that the introduction of telework is a complex process and has profound implications for the organization. However, this research critically lacks any guidance for the decision maker in determining the feasibility of implementing telework. We propose a framework for a telework suitability test to determine the appropriateness of telework, in a particular situation. This telework suitability test integrates existing research findings with future research areas.  相似文献
