We analyze the effects of the unprecedented rise in trade between Germany and “the East” (China and Eastern Europe) in the period 1988–2008 on German local labor markets. Using detailed administrative data, we exploit the cross‐regional variation in initial industry structures and use trade flows of other high‐income countries as instruments for regional import and export exposure. We find that the rise of the East in the world economy caused substantial job losses in German regions specialized in import‐competing industries, both in manufacturing and beyond. Regions specialized in export‐oriented industries, however, experienced even stronger employment gains and lower unemployment. In the aggregate, we estimate that this trade integration has caused some 442,000 additional jobs in the economy and contributed to retaining the manufacturing sector in Germany. This is almost exclusively driven by the rise of Eastern Europe, not by China. We also conduct an analysis at the individual worker level, and find that trade had a stabilizing overall effect on employment relationships. 相似文献

Background
Quick protective reactions such as reaching or stepping are important to avoid a fall or minimize injuries. We developed Kinect-based choice reaching and stepping reaction time tests (Kinect-based CRTs) and evaluated their ability to differentiate between older fallers and non-fallers and the feasibility of administering them at home.Methods
A total of 94 community-dwelling older people were assessed on the Kinect-based CRTs in the laboratory and were followed-up for falls for 6 months. Additionally, a subgroup (n?=?20) conducted the Kinect-based CRTs at home. Signal processing algorithms were developed to extract features for reaction, movement and the total time from the Kinect skeleton data.Results
Nineteen participants (20.2 %) reported a fall in the 6 months following the assessment. The reaction time (fallers: 797?±?136 ms, non-fallers: 714?±?89 ms), movement time (fallers: 392?±?50 ms, non-fallers: 358?±?51 ms) and total time (fallers: 1189?±?170 ms, non-fallers: 1072?±?109 ms) of the reaching reaction time test differentiated well between the fallers and non-fallers. The stepping reaction time test did not significantly discriminate between the two groups in the prospective study. The correlations between the laboratory and in-home assessments were 0.689 for the reaching reaction time and 0.860 for stepping reaction time.Conclusion
The study findings indicate that the Kinect-based CRT tests are feasible to administer in clinical and in-home settings, and thus represents an important step towards the development of sensor-based fall risk self-assessments. With further validation, the assessments may prove useful as a fall risk screen and home-based assessment measures for monitoring changes over time and effects of fall prevention interventions.103.
中国人口的不确定性研究 总被引:1,自引:0,他引:1
文章对2000年人口普查所反映的生育水平、出生性别比和人口年龄结构等主要人口指标存在的不确定性进行了梳理,并运用概率人口预测方法系统讨论了中国未来人口变动趋势过程中相关人口变量的不确定性问题。结果显示,当前对中国生育率水平、出生性别比和低龄儿童人口数量的估计都存在很大的差异。这些差异直接影响中国人口目前和未来的不确定性。 相似文献

Qualifikation von Ausbildungssupervisoren in der Sozialen Arbeit – Kontexte,Methoden und Erfahrungen
Wolfgang Witte 《Organisationsberatung, Supervision, Coaching》2018,25(4):459-469
This article moots the issue of how to support students of social work and social pedagogy to develop the prerequisites for a professional exercise within their future vocational role by dint of supervision. Academical training has to offer spaces for reflecting the relationship between clients and their assistants and for the student’s self-development as well. Methodical settings are reflected for the vocational training of students. Of what kind are the relationships between knowledge transfer, practical guidance and supervision? This article pleads for supervision as an educational program and specifies the qualifications for supervisors. 相似文献

This study examined the relation of gender and Sensation Seeking (SS) Scale scores to undergraduates' ratings of their past/present and expected future participation in four leisure activities that usually involve betting money. Subjects completed McKeachnie's (1975) Leisure Activities Blank (LAB), which included the gambling items, and Zuckerman's (1979) SS Scale. Men reported significantly more past/present leisure gambling than women; gender differences were insignificant in ratings of expected future gambling. No significant differences in reported past/present gambling related to any SS scale score. However, expected future gambling ratings were associated with scores on two SS subscales: Disinhibition (DIS) and Boredom Susceptibility (BS). Both male and female subjects with high DIS scores rated the frequency of expected future gambling higher than did subjects with low DIS scores. High BS scores were associated with high ratings of expected future gambling in the data for women subjects only. These results suggest that personality factors, among them SS, are more influential than early experience or sex-role socialization in determining a young adult's interest in gambling. 相似文献

Closure under the operation of forming coherent systems of independent components is a desirable property for a class of life distributions. We show that the NBUFR class possesses this property. 相似文献
