In 1968, employers filed 1,091 petitions resulting in 377 elections, 42.4 percent of which unions won. In 1992, the most recent year for which data are available, employers filed 247 petitions, 66 elections were held, and the union victory rate was less than 25 percent. This research examines both the legal environment and the activity levels of employer-initiated (RM) elections over the past 25 years.  相似文献

Has the Internet Increased Trade? Developed and Developing Country Evidence   总被引:2,自引:0,他引:2  
Developing countries export more to developed, but not other developing countries, when Internet penetration is higher. Although this could be because Internet penetration stimulates exports, it could also be because trade openness encourages Internet use. To test the direction of causation, we allow Internet use to be determined endogenously using countries' regulation of data services as an instrument. The results suggest that access to the Internet does improve export performance in developing countries, although not in developed countries. In other words, improving Internet access in a developing country will stimulate exports from that country to rich countries. (JEL F15 )  相似文献

THE LONG ARM OF THE LAW:   总被引:1,自引:0,他引:1  
This article offers a test of labeling theory by exploring whether contact with school and justice system authorities has long-term, negative, and independent effects on an individual's labor market success. We use the National Longitudinal Survey of Youth (NLSY79), a large and nationally representative sample, to examine whether experiences ranging from school suspension to incarceration during ages 15–23 can predict occupational status, income, and employment during ages 29–37. Unlike previous studies, we control for an exhaustive list of variables: social background, human capital, prior deviant behavior, family status, and local context. Our findings generally support labelling theory. Severe forms of labeling like sentencing and incaraceration have the strongest negative effects, though among females suspension or expulsion from school also has consistently negative effects. We conclude with a discussion of how labeling might reduce employment chances, with a focus on gender differences.  相似文献

The MRI problem-solving and the recently popular solution-amplifying approaches to brief therapy are described as based upon the same process point of view. A process view is described in contrast to a structural view of human interactions. It is argued that an exclusive focus on amplifying perceived solutions without clearly defining problem patterns may become a problem. Clear articulation of a therapist's assumptions about human interaction, problems, and therapeutic solutions is strongly advocated. Creativity, flexibility, effectiveness, and efficiency are likely to be by-products of such clarity. Without it, our therapeutic zeal in searching for solutions is likely to become a problem.
A Japanese coastal village was once threatened by a tidal wave, but the wave was sighted in advance, far out on the horizon, by a lone farmer in the rice fields on the hillside above the village. At once he set fire to the fields, and the villagers who came swarming up to save their crops were saved from the flood.  相似文献

The Fay–Herriot model is a standard model for direct survey estimators in which the true quantity of interest, the superpopulation mean, is latent and its estimation is improved through the use of auxiliary covariates. In the context of small area estimation, these estimates can be further improved by borrowing strength across spatial regions or by considering multiple outcomes simultaneously. We provide here two formulations to perform small area estimation with Fay–Herriot models that include both multivariate outcomes and latent spatial dependence. We consider two model formulations. In one of these formulations the outcome‐by‐space dependence structure is separable. The other accounts for the cross dependence through the use of a generalized multivariate conditional autoregressive (GMCAR) structure. The GMCAR model is shown, in a state‐level example, to produce smaller mean square prediction errors, relative to equivalent census variables, than the separable model and the state‐of‐the‐art multivariate model with unstructured dependence between outcomes and no spatial dependence. In addition, both the GMCAR and the separable models give smaller mean squared prediction error than the state‐of‐the‐art model when conducting small area estimation on county level data from the American Community Survey.  相似文献

A sexual health disparity exists among U.S. Latinas, who have rates of sexually transmitted infections (STIs) that are more than double their peers. Previous research has identified acculturation and religiosity as key social determinants of sexual health, but such findings have been inconsistent, with some researchers identifying protective benefits and other researchers noting increased risk. The purpose of this study was to explain how intrinsic and extrinsic religiosity as well as acculturation predict risky sexual behavior using Structural Equation Modeling of a nationally representative sample of self-identified Latinas (N = 1,168) from the National Longitudinal Survey of Adolescent Health. Results indicated that intrinsic religiosity and acculturation assert protective effects while extrinsic religiosity increases risk. Recommendations for policy, intervention, and future research are offered.  相似文献

An attachment-sensitive formulation is presented for a 9-year-old adopted girl with a complex presentation of oppositionality, separation anxiety, and attachment problems. Session-by-session observational data of an evidence-based treatment demonstrates the transactional nature of the carer-child interactions that drove an improvement in attachment behaviors, as well as oppositional and anxiety symptoms at home. Most importantly, a placement in imminent danger of breakdown was stabilized, allowing the child more time to negotiate a reliable attachment to her new carer. Thus, the evidence-base can be used to develop personalized treatment packages for complex adoption cases consistent with the relevant practice parameters.  相似文献

The form of historicism that has had most impact in the context of literary theory in the Anglophone academy is new historicism. The label new historicism was applied to an initially American mode of literary study that emerged in the late 1970s in the context of “heated discussions” surrounding theorised forms of literary study like Marxism, feminism, psychoanalysis, structuralism, post‐structuralism and deconstruction. Having emerged in this context, however, new historicism — and the more broader forms of historicist study that have migrated across a variety of disciplines in the arts and humanities — has thrived in the Academy while interest in “theory” has declined since the 1990s. In this article I propose to look closely at the reasons for the survival and success of new historicism, even as other, more radical modes of analysis have become unfashionable.  相似文献
