The Knowledge‐Information‐Service Era (KIS) is reflecting exponential changes in social, economic, government, career, education, work, and other life systems. Changes in work and workplace present a challenge to education and “educationplace” to provide concentrated attention to career development. Career education is an answer to the challenge. School counselors have a changing role in supporting the needs of students and workers for basic academic skills, productive work habits, work values, and means of relating paid and unpaid work as parts of total lifestyle. 相似文献

It has long been suggested that a firm's social responsiveness is a function, in part, of the state of the economy. Could it be that corporate social involvement is only feasible when the economy is healthy? Data from 183 major corporations suggests that via social forecasting, social responsiveness is: (A) a vital part of many corporations' strategic planning efforts, (B) not de-emphasized, but possibly encouraged, during down turns in the economy, and (C) receiving greater attention each year by numerous corporations. 相似文献

Following the Supreme Court's Kodak decision, numerous antitrust cases have revolved around practices of manufacturers which deter independent service organizations (ISOs) from servicing the manufacturer's equipment. Such practices include tying equipment sales to service, tying service sales to other "aftermarket" products, and refusing to sell replacement parts to ISOs. We show that interbrand systems competition without ISOs curbs service and equipment price distortions and, under plausible conditions, confers greater benefits to users of durable equipment than intrabrand service competition with ISOs. Hence, the effect of manufacturers' practices that foreclose ISOs from service aftermarkets can be efficiency promoting rather than anticompetitive. 相似文献

Scholars of public management have consistently found that managementmatters, but little research has considered how much managementmatters or whether the link between management and performancemay be contingent on various factors. This article further investigatesthe link between management and performance by examining thefunctional form of the relationship. Analyses using data from1000+ public organizations point to some diminishing returns.Results suggest that networking with other organizations mightnot always result in gains for the organization. Findings alsoshow how managerial quality and differences in organizationalstaff can affect this relationship. 相似文献

Regulation and Risk in Social Work: The General Social Care Council and the Social Care Register in Context 总被引:1,自引:0,他引:1
The 2000 Care Standards Act led to the setting up the GeneralSocial Care Council (GSCC) as the new governing professionalbody for social workers and other social care employees in England.1The GSCC published national Codes of Practice for social carestaff and their employers in 2002, whilst 1 April 2003 saw theintroduction of the Social Care Register. The stated aim ofthese developments is to protect the public, improve the qualityof care offered by social workers and increase public confidencein the profession. However, such intentions disguise the increasein regulatory control that the GSCC and social care employershave gained over the workforce—intrusions that have metrelatively little criticism. By locating these developmentswithin a broader social context, one in which risk and its managementare at the forefront of contemporary social policy and practice,this paper argues that underlying the debate is a climate offear and distrust in which there is a tendency to view peopleas either vulnerable, dangerous or both. Such a degraded viewof the subjects of social work also pertains to social workersthemselves, who are simultaneously seen as assessors of risk,at risk and as a risk. 相似文献

Cluster analysis is the automated search for groups of homogeneous observations in a data set. A popular modeling approach
for clustering is based on finite normal mixture models, which assume that each cluster is modeled as a multivariate normal
distribution. However, the normality assumption that each component is symmetric is often unrealistic. Furthermore, normal
mixture models are not robust against outliers; they often require extra components for modeling outliers and/or give a poor
representation of the data. To address these issues, we propose a new class of distributions, multivariate t distributions with the Box-Cox transformation, for mixture modeling. This class of distributions generalizes the normal distribution
with the more heavy-tailed t distribution, and introduces skewness via the Box-Cox transformation. As a result, this provides a unified framework to simultaneously
handle outlier identification and data transformation, two interrelated issues. We describe an Expectation-Maximization algorithm
for parameter estimation along with transformation selection. We demonstrate the proposed methodology with three real data
sets and simulation studies. Compared with a wealth of approaches including the skew-t mixture model, the proposed t mixture model with the Box-Cox transformation performs favorably in terms of accuracy in the assignment of observations,
robustness against model misspecification, and selection of the number of components. 相似文献

Using data on all Norwegians born 1935–68, we analyze the associations between mortality and a combined indicator of fertility and marital or partnership status and history. The focus is on ages 40–73 and the years 1980–2008 (30 million person‐years of observations and 117,000 deaths). Among men in first marriages, the childless have 36 percent higher mortality than those with two or more children. The corresponding figure for women is 61 percent. The never‐married have higher mortality and are differentiated even more by parenthood status. Thus, childless never‐married men and women have mortality three times as high as those who are married and have two or more children. The apparent advantage associated with having at least two children is smallest among men who divorced before their oldest child's tenth birthday. Having step‐children has no association with mortality for those without natural children but is associated with higher mortality among the parous. 相似文献

This study applied religious coping theory to examine the relationship between participants' perceptions that lesbian and gay (LG) individuals desecrate Christian values (the stressor) and anti-LG attitudes (the response) and whether religious coping influences the relationship between these variables. Greater agreement with desecration messages was associated with higher levels of anti-LG attitudes. Positive religious coping was associated with lower levels of anti-LG attitudes while negative religious coping was associated with higher levels. Greater exposure to messages that LG individuals desecrate Christian values was associated with greater agreement with those messages. Longitudinal studies with more diverse samples are needed to examine causality and the generalizability of the findings. However, these results have implications for preventing and mitigating anti-LG attitudes. 相似文献

Forecasting destructive hurricane potential is complicated by substantial, unexplained intraannual variation in storm-specific power dissipation index (PDI, or integrated third power of wind speed), and interannual variation in annual accumulated PDI (APDI). A growing controversy concerns the recent hypothesis that the clearly positive trend in North Atlantic Ocean (NAO) sea surface temperature (SST) since 1970 explains increased hurricane intensities over this period, and so implies ominous PDI and APDI growth as global warming continues. To test this "SST hypothesis" and examine its quantitative implications, a combination of statistical and probabilistic methods were applied to National Hurricane Center HURDAT best-track data on NAO hurricanes during 1880-2002, and corresponding National Oceanographic and Atmospheric Administration Extended Reconstruction SST estimates. Notably, hurricane behavior was compared to corresponding hurricane-specific (i.e., spatiotemporally linked) SST; previous similar comparisons considered only SST averaged over large NAO regions. Contrary to the SST hypothesis, SST was found to vary in a monthly pattern inconsistent with that of corresponding PDI, and to be at best weakly associated with PDI or APDI despite strong correlation with corresponding mean latitude (R(2)= 0.55) or with combined mean location and a approximately 90-year periodic trend (R(2)= 0.70). Over the last century, the lower 75% of APDIs appear randomly sampled from a nearly uniform distribution, and the upper 25% of APDIs from a nearly lognormal distribution. From the latter distribution, a baseline (SST-independent) stochastic model was derived predicting that over the next half century, APDI will not likely exceed its maximum value over the last half century by more than a factor of 1.5. This factor increased to 2 using a baseline model modified to assume SST-dependence conditioned on an upper bound of the increasing NAO SST trend observed since 1970. An additional model was developed that predicts PDI statistics conditional on APDI. These PDI and APDI models can be used to estimate upper bounds on indices of hurricane power likely to be realized over the next century, under divergent assumptions regarding SST influence. 相似文献
