We analyze the effects of the 2011 Egyptian protests on the relative labor market conditions of women using panel data from the Egypt Labor Market Panel Survey (ELMPS). Using unique information from the Statistical Database of the Egyptian Revolution, we geocode each “martyr”, i.e. demonstrators who died during the protests, based on the location of the political incident. We construct our measure of the intensity of the protests – the district-level number of “martyrs” – and rely on a Difference-in-Differences approach. We find that the 2011 protests have reduced intra-household differences in labor force participation by increasing women's employment and unemployment relative to men. Women's employment relative to men increased in both the private and informal sectors. Our estimates suggest how economic uncertainty such as the one associated to the recent protests may undermine the importance of cultural factors and attitudes towards female work. We link these findings to the literature showing how a relevant shock to the labor division between women and men may have long run consequences on the role of women in society.  相似文献

Aim: Progel Pleural Air Leak Sealant (Progel) is currently the only sealant approved by the FDA for the treatment of air leaks during lung surgery. This study was performed to determine whether Progel use improves hospital length of stay (LOS) and hospitalization costs compared with other synthetic/fibrin sealants in patients undergoing lung surgery.

Methods: The US Premier hospital database was used to identify lung surgery discharges from January 1, 2010 to June 30, 2015. Eligible discharges were categorized as “Progel Sealant” or “other sealants” using hospital billing data. Propensity score matching (PSM) was performed to control for hospital and patient differences between study groups. Primary outcomes were hospital LOS and all-cause hospitalization costs. Clinical outcomes, hospital re-admissions, and sealant product use were also described.

Results: After PSM, a total of 2,670 discharges were included in each study group; baseline characteristics were balanced between groups. The hospital LOS (mean days?±?standard deviation, median) was significantly shorter for the Progel group (9.9?±?9.6, 7.0) compared with the other sealants group (11.3?±?12.8, 8.0; p?<?.001). Patients receiving Progel incurred significantly lower all-cause hospitalization costs ($31,954?±?$29,696, $23,904) compared with patients receiving other sealants ($36,147?±?$42,888, $24,702; p?<?.001).

Limitations: It is not possible to say that sealant type alone was responsible for the findings of this study, and analysis was restricted to the data available in the Premier database.

Conclusions: Among hospital discharges for lung surgery, Progel use was associated with significantly shorter hospital LOS and lower hospitalization costs compared with other synthetic/fibrin sealants, without compromising clinical outcomes.  相似文献

What are the common characteristics among individuals who justify attacks on civilians? Using nationally representative Gallup World Poll surveys of 30,787 individuals from 27 developing countries in different parts of the world, this paper identifies the partial correlates of extremism. The results suggest that the typical extremist who supports attacks on civilians is more likely to be young, unemployed, and struggling to make ends meet, relatively uneducated, and not as religious as others, but more willing to sacrifice own life for his or her beliefs. Gender and marital status are not found to explain the individual‐level variation in attitudes toward extremism. These results are robust to various sensitivity analyses, although some of them vary in magnitude and significance across countries and geographic regions.  相似文献

Many studies of technology acceptance have noted that new technology can have far-reaching effects, dramatically changing the environment (e.g., work, home, school) in which we use the technology. The current research considers an equity comparison perspective on technology acceptance and usage in the context of online discussion tools based on the equity implementation model (EIM). The EIM applies equity theory to assess user net outcomes related to adopting new technology in comparison to the net outcomes of other technology stakeholders. Facilitating conditions with the new technology are investigated as a moderating factor on intentions and usage. Equity theory and social comparisons provide an alternative lens for understanding technology acceptance that may capture broader issues related to the changes resulting from new technology. This research describes what we believe to be a first effort to operationalize social comparisons of equity in the context of technology acceptance. A survey instrument measuring social comparisons of net outcomes is developed, and a longitudinal, empirical study is conducted in the context of online discussion forums. The research model is also investigated within a nomological network of technology acceptance constructs. The results indicate that the model provides explanatory power comparable to existing models of technology acceptance and that outcome comparisons provide unique insight beyond known determinants of intentions and usage.  相似文献

ABSTRACT

Digital technologies have become an increasingly prominent feature of children’s lives both within and outside educational environments (McCoy, Quail, and Smyth 2012. Influences on 9-Year-Olds’ Learning: Home, School and Community. Dublin: Department of Children and Youth Affairs). Despite considerable media debate, we have little robust evidence on the impact of technology use on children’s development, both academically and socially. Much of the literature in this area relies on small-scale cross-sectional studies. Using longitudinal data on 8500 9-year-old children in Ireland, we examine the influence of early mobile phone ownership on children’s performance in reading and maths between 9 and 13 years of age. Across both reading and maths domains, children who already report owning a phone by the age of nine fare less well in terms of their academic development as they move into adolescence. The measured effects are sizeable, implying about 4 percentile lower ranking on standardised tests for an average student. Our results are consistent with the idea that there may be significant educational costs arising from early mobile phone use by children. Parents and policymakers should consider whether the benefits of phone availability for children are sufficiently large to justify such costs. We suggest a range of direct and indirect cognitive effects that could help explain these results.  相似文献

High-density urban living means that urban green spaces are important nodes of contact with nature. This study examines expected outcomes that motivate people to seek green spaces in urban settings. A sample of Swiss residents were presented with Shin, Kwon, Hammitt, and Kim's (2005 Shin, W., Kwon, H., Hammitt, W. and Kim, B. 2005. Urban forest park use and psychosocial outcomes: A case study in six cities across South Korea. Scandinavian Journal of Forest Research, 20(5): 441447. [Taylor & Francis Online], [Web of Science ®] [Google Scholar]) psychosocial outcomes scale and asked which activities they choose to undertake in nearby natural areas. The most important motivations for visiting nearby green spaces were related to restoration, with social bonding as a desirable side benefit. There were few observable differences between urban and rural residents and level of education attained. Older people are motivated to visit nearby green spaces by the wish to seek social contact while younger people are motivated by the wish to seek escape and to reflect. This study contributes to the understanding of the psychosocial outcomes that residents expect from engaging in an activity in an urban green space.  相似文献

This article sets out to highlight the importance of adopting customer orientation and information and communications technology (ICT) in tourism service delivery if the rural tourism sector is to succeed. A model is proposed and validated which encompasses the effects of customer orientation adoption and the use of ICT on the rural tourism sector, taking into account the enterprises’ financial results, improvements to the rural destination, and the more personal, intangible impact on the owner-manager. The major contributions of this work are in finding that customer orientation adoption that contributes to ICT use, and that both ICT use and customer orientation adoption contribute to better outcomes from rural tourism activity.  相似文献

Objective:

To characterize the burden of idiopathic painful peripheral neuropathy with small fiber involvement (idiopathic SFN) by pain severity in the US.

Methods:

One hundred previously diagnosed idiopathic SFN subjects were enrolled during routine office visits. Subjects completed a one-time questionnaire, and investigators reported clinical characteristics and healthcare resource use, based on 6 month retrospective chart review. Annualized direct and indirect costs were estimated. Results were stratified across pain severity groups.

Results:

Mean age was 63.5 years; 53.0% were female; 76.0% had moderate or severe pain. Most common comorbidities were sleep disturbance/insomnia (37.0%), anxiety (34.0%), and depressive symptoms (33.0%). Overall mean health status (0.59; ?0.11–1.00 scale), physical and mental health (31.7 and 45.6, respectively, 0–100 scale), sleep index (45.1; 0–100 scale), and pain interference with function (5.0; 0–10 scale) differed by pain severity, with worse outcomes among those with greater pain (all p?Conclusions:

Idiopathic SFN subjects with pain experience moderate or severe pain, which negatively impacts health status, function, and productivity, and leads to substantial direct and indirect costs.  相似文献

We revisit the study of organizational goals, outcomes, and assessment of performance that together define the process leading to ‘success’. We begin by conducting a systematic review of existing research which allows us to develop an integrative framework discussing this large body of work. We then describe contemporary research examples in light of our proposed framework. We close by proposing four new areas to continue to advance the field: reconceptualizing performance (and success) as achievement of goals; diversity of goal systems in research designs, and their relationship with the purpose of an organization; multilevel and temporal dynamics; and governance of goal setting. Overall, our efforts inform future research on organizational success in the context of our new societal challenges and accomplish the intriguing task of re-defining success in management studies.  相似文献
