Beginning in the late 1970s, a series of reforms to improve industrial productivity were implemented in China. We estimate changes in productivity growth and identify its sources in the post-reform period 1980-85. Our work is based on the newest and most comprehensive data set available on Chinese industrial activities. Productivity growth estimates are shown to be strongly affected by output specification. Overall, we find sharp increases in productivity growth in the 1984-85 period as compared to the 1980-84 period. Collective and private enterprises show higher output and productivity gains than do state-owned enterprises. 相似文献

Mostly operating from a risk and risk-reduction paradigm, existing research on migrants in Vietnam tends to conceptualize sex and risky sexual behaviors as isolated life domains. This study begins to develop a contextually rich understanding of migrants’ sex lives by examining the relationships among sex, work, and the constant pendulum-like migrating movements of 23 Vietnamese married migrants in Hanoi and Ho Chi Minh City. Using data from in-depth interviews, it was found that most participants had no sex in the city; this was followed by visits to the home village, where they had sex with their spouses as often as possible to make up for the “long drought” in the city. Within this sexual schema, sex came secondary, and even peripherally, to migrants’ working lives; thus, exhaustion from work was cited by migrants as the overwhelming factor leading to their sexual problems. This study suggests that migrants’ intimate lives are more strongly linked to their working lives than has previously been recognized, and that their sexual behaviors should be viewed in tandem with the hardships of their working lives. 相似文献

Purpose: The purpose of this study was to validate the Multidimensional Scale of Perceived Social Support (MSPSS) among middle-aged Korean women with type 2 diabetes. Methods: Data were collected from 123 middle-aged Korean women with diabetes. Construct and concurrent validity were examined using factor analysis. Results: Factor analysis extracted three factors: spouse, family, and friends. The MSPSS had relatively good concurrent validity (r = .66, p < .0001), construct validity, and strong reliability (Cronbach's alpha = .90). Conclusion: We concluded that the MSPSS is a simple and well-established instrument to measure social support in middle-aged Korean women with diabetes. 相似文献

This paper addresses the problem of modifying the edge lengths of a tree in minimum total cost such that a prespecified vertex becomes the 1-center of the perturbed tree. This problem is called the inverse 1-center problem on trees. We focus on the problem under Chebyshev norm and Hamming distance. From special properties of the objective functions, we can develop combinatorial algorithms to solve the problem. Precisely, if there does not exist any vertex coinciding with the prespecified vertex during the modification of edge lengths, the problem under Chebyshev norm or bottleneck Hamming distance is solvable in \(O(n\log n)\) time, where \(n+1\) is the number of vertices of the tree. Dropping this condition, the problem can be solved in \(O(n^{2})\) time. 相似文献

The paper develops a production function for the Global Ocean Health Index (OHI) for 2013. Data from the Ocean Health Statistics, plus from the Human Development Index (HDI) for 151 countries are used. We employ two-stage regression model to conduct this evaluation. The Tobit model, used to obtain the estimated dependent variable, results show Coastal Protection, Livelihoods and Economies, Tourism and Recreation, Iconic Species, Clean Water and Biodiversity, Food Provision, Artisanal Fisheries Opportunities, Natural Products, and Carbon Storage are significant variables. The rank regression in the second stage showed that HDI and Marine Protected Areas (MPAs) significantly influenced the predicted value of the OHI. Policy makers should note that biodiversity increases have the greatest effect on OHI, and its improvement is within reach of even the poorest country. Countries with varying levels of resource endowment may choose different techniques to improve OHI, but the implementation of MPAs should be priority. 相似文献

Nonverbal behavior coding is typically conducted by “hand”. To remedy this time and resource intensive undertaking, we illustrate how nonverbal social sensing, defined as the automated recording and extracting of nonverbal behavior via ubiquitous social sensing platforms, can be achieved. More precisely, we show how and what kind of nonverbal cues can be extracted and to what extent automated extracted nonverbal cues can be validly obtained with an illustrative research example. In a job interview, the applicant’s vocal and visual nonverbal immediacy behavior was automatically sensed and extracted. Results show that the applicant’s nonverbal behavior can be validly extracted. Moreover, both visual and vocal applicant nonverbal behavior predict recruiter hiring decision, which is in line with previous findings on manually coded applicant nonverbal behavior. Finally, applicant average turn duration, tempo variation, and gazing best predict recruiter hiring decision. Results and implications of such a nonverbal social sensing for future research are discussed. 相似文献

The conventional logic supported by research and statistics suggests that there will be more child maltreatment as the economy becomes worse and less child maltreatment as the economy becomes better. However, in some local jurisdictions in California, statistics indicate the opposite. A closer examination of one county, San Mateo, suggests that this may be due to the fact that the County has a very high Self-Sufficiency Standard in which people get jobs with incomes that do not exceed the Standard, but in fact disqualifies them from the safety net of Federal benefits. Further, children born around the time of the last recession have a higher chance of adverse mental health issues and are now entering schools with issues that may reflect child abuse and neglect. 相似文献
