陕西关中地区金融发展与经济增长关系的实证分析   总被引:8,自引:0,他引:8  
以陕西关中地区为研究对象,通过选取其1990~2003年金融发展和经济增长的相关数据,通过建立计量经济模型和葛兰杰因果关系检验,结果发现实际利率、金融相关比率与关中地区经济增长率之间有着较强的负相关性;金融发展与经济增长之间的因果关系是单向的,即表现为经济增长带动了金融发展,而金融发展对关中地区经济增长的推动作用并不显著,这说明关中地区还存在着较为严重的金融抑制现象。为此,提出必须从金融机构的数量扩张与结构优化两个方面强化金融对经济增长的支持作用。  相似文献

In this study, we analyse whether there are differences in attitudes towards nonprofit organizations (NPOs) between the generational cohorts of Baby Boomers, Generation X, and Millennials. We do so by analysing survey data from Switzerland in two steps, a Bayesian estimation as well as a cluster analysis. The overall results suggest that there are, at best, only few and small intergenerational differences: the only consistent effect we find are the more negative attitudes of the Baby Boomer cohort towards professional associations and towards sports NPOs, but those differences could be due to life cycle rather than intergenerational effects. Overall, our results suggest that the Millennial generational cohort is at least as interested in and willing to engage with NPOs as previous generational cohorts.  相似文献

Background

Physical activity (PA) is generally beneficial for bone health, but the effect of high levels of PA over many years, in older women, is unknown.

Methods

T-score from Dual-energy X-ray absorptiometry (DXA), and self-reported baseline characteristics were recorded for 24 female, cross-country-skiing-competitors, aged 68–76?years, from the Birkebeiner Ageing Study. Data from 647 women in the same age range from the Tromso-6 population study, with recorded DXA findings, were used for comparison.

Results

The athletes reported a median(range) of 9(1–34) participations in the 54?km, yearly ski-race, indicating long-term PA. They also reported more moderate and high levels of PA than women in the general population (52% vs. 12 and 30% vs. 0%, respectively). The athletes had lower body mass index (BMI) than the controls (mean BMI 21.7 vs 26.9?kg/m2, p?<?0.001). As many as 22/24(92%) of the athletes and 477/647(74%) of the controls had a low bone mineral density (BMD) (T-score?<???1), p 0.048, Pearson chi square test. Odds ratio (OR) of low BMD was 3.9 in athletes vs. controls (p 0.048, logistic regression), but adjusting for BMI largely diminished the effect estimate, which was no longer statistically significant (aOR 1.81, p 0.432). The proportion of self-reported fractures was the same in the two groups.

Conclusions

This pilot study suggests that long-term, high levels of PA are associated with low bone mineral density in older women, and the finding might be due to differences in BMI. Despite the lower bone mineral density the athletes did not report more fractures.

The authors used cross-lagged analyses to examine the across-time influences on and consequences of adolescents' pregnancy intentions, wantedness, and regret. One hundred pregnant Latina adolescents were studied during pregnancy and at 6 and 12 months postpartum. The results revealed 4 main findings: (a) similar to what has been found in adult women, adolescents' lower prenatal pregnancy intendedness and wantedness predicted initial difficulties in parenting; (b) frequent depression symptoms predicted subsequent lower pregnancy intendedness and wantedness; (c) adolescents' poor mental health and harsh parenting of their child predicted subsequent higher childbearing regret, and (d) high childbearing regret and parenting stress were reciprocally related across time. In addition, adolescents' wantedness of their pregnancy declined prenatally to postbirth, and strong pregnancy intendedness and wantedness were not concurrently related to adolescents' poor prenatal mental health. The findings reveal how adolescents' thoughts and feelings about their pregnancies are influenced by and predictive of their mental health and parenting experiences.  相似文献

South Africa's approach to care provision in the era of HIV/AIDS is home‐ and community‐based care, but in reality care for ill people in the home is provided on an unpaid basis, predominantly by women. But how much do they spend on this care work, in time and money? And what economic consequences does this policy have, particularly for poorer women? This article is based on findings from a study that focuses on unpaid care provision within the home for those in late‐stage HIV/AIDS in KwaZulu‐Natal, South Africa, and specifically on the costs of such provision. The findings show that female caregivers are bearing the bulk of the costs of care provision for ill people within the home on an unpaid basis. Home‐based care is cost‐effective for the provincial government but not for unpaid caregivers who are subsidizing the provincial economy. While hospital care for people with HIV/AIDS has been capped, home‐based care services have not been increased to a commensurate level. Unpaid caregivers and ill people within the home are largely disconnected from the health system. The analysis clearly shows that the home‐based care policy is not resulting in appropriate or sufficient support for these individuals in need and needs to be revised.  相似文献

This paper presents the results of an independent evaluation of the Multi-dimensional Treatment Foster Care (MTFC) programme for young offenders in England, where it is known as Intensive Fostering (IF).

Methods

A quasi-experimental, mixed methods study was carried out at the three pilot sites, with a total sample of 47 at follow up. Young people sentenced to IF were compared to a similar group, matched on the eligibility criteria for IF, the majority of whom were sentenced to custody. The groups were well-matched in terms of their characteristics and criminal histories. Official data on reconviction were collected at baseline and one year after entry to the IF placement or release from custody (Stage 1), and further data on programme completion and secondary outcomes were collected via interviews with young people and parents and questionnaires to professionals at baseline and follow up. Official data on reconviction were also collected one year after exit from the IF placements (Stage 2).

Results

At Stage 1 the IF group were less likely to be reconvicted, had committed fewer and less serious recorded offences, on average, and took longer to commit their first recorded offence. At this point the IF group were more likely to be living with their families and less likely to be in custody than the comparison group. However by Stage 2 no significant differences in patterns of reconviction remained.

Conclusions

IF successfully contained a high-risk group in the community, but the effects of the intervention washed out once they left their foster placements. Environmental effects on entry to and exit from the IF placements may help to explain the results at both stages.  相似文献

ABSTRACT

Women who decide to leave street-based sex work often struggle with addiction, trauma-related mental health consequences, and exclusion from employment and housing. To offer recommendations for social service providers, this article draws upon primary data from interviews and surveys with 87 residents at a transitional housing facility for women leave sex work to elucidate: 1) a demographic profile of the women, 2) life history patterns and circumstances that encourage women to leave street-based sex work and 3) recommendations for service providers. Results indicate the need for service providers to assist women with basic needs, strengthen referral networks, and extend trauma-informed services.  相似文献

Folklore is the artistic expression of belief. The various forms of folklore change and adapt to reflect changing circumstances and changing views of the world. When Ukrainians came to Canada, they brought their folklore, ballads included, with them. In the new land, ballads helped voice the struggles of the Ukrainian Pioneers. Examining a collection of ballads made approximately sixty years after Ukrainians began arriving on the Prairies shows that the ballads performed in Canada spoke of real problems, problems attested in both folk sources and historical records. These include the physical hardship of life on an acreage, male absence as they went to work on the railroad, and the tension between women and their daughters-in-laws, who were left to struggle on their own. Ukrainian girls attracted to non-Ukrainians were seen as problematic, as were men seeking solace in alcohol and infidelity. And there were many other Canadian issues for which traditional ballads provided a powerful means of expression. The ballad tradition was modified through selection, i.e., only relevant songs continued to be performed. It was also changed internally and individual ballad texts were altered by the addition of new terminology and new ideas. This is especially true when attitudes in Canada differed from those in Ukraine. A very important change in attitude applies to magic. While the use of magic is treated ambiguously in ballads performed in Ukraine, it is routinely condemned in those performed in Canada.  相似文献
