This paper exploits a Danish spatial dispersal policy on refugees, which can be regarded as a natural experiment to investigate
the influence of regional factors on recent immigrants’ location choices. The main push factors are lack of co-nationals and
immigrants. Additional push factors are lack of rental, including social, housing and lack of institutions for qualifying
education, which explain why recent immigrants are attracted to large cities. Finally, placed refugees tend to leave locations
with relatively high regional unemployment, and there is indirect evidence of welfare seeking.

Most of the studies on the determinants of individual gambling behaviour rely on cognitive theories. In our study, we argue that, besides cognitive factors, several social factors might play an important role as well. We analyse data from an ad hoc webmail survey conducted on about 2000 undergraduate students enrolled in a large public university in the Northern Italy in the academic year 2012–13. Using a variety of statistical techniques (standard regression models, boosted regression trees and structural equations models), we show that social variables affect both participation in gambling in the past year and latent gambling propensity. In particular, controlling for several proxies for individual cognitive ability and understanding of probability, gambling propensity is positively affected by the degree of gambling in the social surrounding (parents, peers, neighbourhood) and the acceptability of gambling activities to the individual. Moreover, in our sample of college students the role of social factors appears to be larger than that of cognitive factors, and this is consistent across different types of models and specifications. 相似文献

We examined 359 women aged 45–65 years who visited Jordan University Hospital between February and November 2014. The menopausal symptoms were assessed using a validated Arabic version of the menopause rating scale. The mean age at menopause was 49.4 years. Women aged 50–55 years more frequently exhibited hot flushes and vaginal dryness. Although premenopausal women were 1.5 times more likely to experience irritability, perimenopausal women were more likely to experience hot flushes, physical and mental irritability, sexual problems, vaginal dryness, and joint and muscular discomfort. Hence, health care providers should focus on women at all stages of life. 相似文献

Association of the modified frailty index with adverse outcomes after penile prosthesis implantation
Objectives: To investigate frailty as a predictor of surgical outcome in elderly patients undergoing penile prosthesis implantation.Material and methods: A total of 54 elderly patients, above 60 years of age, underwent penile prosthesis implantation between 2012 and 2014. Their data were collected and retrospectively analyzed. A modified frailty index (mFI) was calculated for each patient based on 11 risk factors from the Canadian Study of Health and Aging Frailty Index. The 1-year adverse outcomes were correlated with mFI, patients’ and procedure’s risk factors.Results: Mean age was 64.9?±?5.2 years. No mortality was reported in our patients, however, one-year adverse outcomes were encountered in 43 (79.6%) patients. Among all studied variables, the 1-year adverse outcomes was not significantly association with mFI, but with preoperative glycosylated hemoglobin A1c (HbA1c) (p?=?0.031) and associated Peyronie’s disease (PD) (p?=?0.000). HbA1c, dyslipidemia, hypertension, PD and duration of the procedure were predictive of infection complications (p?0.05). Only PD and HbA1c sustained an independent significant impact.Conclusions: mFI is not a predictive of post-penile prosthesis implantation adverse outcomes in elderly patients with impotence. Degree of diabetic control and association with PD was associated with the 1-year adverse outcomes and infection complications. 相似文献

Background
During the last decades, there has been an alarming and dramatic increase in the number of cesarean births in both developed and undeveloped countries. This increase has not been clinically justified but, nevertheless, has raised an important number of issues.Aim
The aim of this study was to determine the risk factors associated with the high cesarean section rates in Lebanon.Methods
This study is based on a sample of 29,270 Lebanese women who were pregnant between 2000 and 2015. Among these, 14,327 gave birth by cesarean section and 14,943 gave birth vaginally. To identify the risk factors of cesarean section, logistic regression was applied as a statistical method using the SPSS statistical package.Findings
Of the 29,270 pregnant women included in the study, 49% had cesarean sections while 51% gave birth vaginally. Repeat cesarean section accounted for 23% while vaginal birth after cesarean accounted for only 0.2% of deliveries. In addition, weekdays were associated with a preference of providers to carry out more cesarean sections. According to an analysis of our data using logistic regression, the risk factors associated with the increase in cesarean section rates were advanced maternal age, elective cesarean section, malpresentation of fetus, multiple birth, prolonged pregnancy, prolonged labor, and fetal distress.Conclusion
Based on these results, it is recommended that a new health policy be implemented to reduce the number of unnecessary cesarean deliveries in Lebanon. 相似文献119.
学术期刊是学术和学科建设的重要阵地,应以学术性作为编辑审稿工作的唯一标准。然而,在现有学术评价体制的影响下,这一工作受到了诸多非学术因素的消极干扰,如以作者身份的高低而非稿件质量的高低来取舍稿件。这一非学术性倾向直接影响了审稿的公正性,也削弱了编辑审稿活动的意义,是学术评价异化的一种反映,不利于学术研究的正常进行和健康发展。编辑应该强化责任意识,自觉克服心理因素,排除思维定势,提高学术判断力,重视学术新人的发现和扶持,从而有效发挥学术期刊在学术和学科建设中的积极作用。 相似文献

关于"IT投资是否能提高企业生产率"这一命题,学界一直众说纷纭,一个很重要的原因在于这些研究建立在IT投资能对企业生产率产生直接影响的假设前提之上,而忽略了IT作用于企业生产率的中间过程。IT投资必须与企业内部生产环境相吻合才能提高企业生产率,IT投资转化为企业生产率的影响因素包括内部因素和外部因素,其中内部因素包括企业管理特征、企业员工特征及企业结构特征;外部因素指的是企业所面临的外部环境。 相似文献
