Donald Edwin Super was a member of the National Career Development Association from 1934 to 1994, a full 60 years. Starting at midcentury, his writings and lectures provided the main impetus to expand vocational guidance to encompass career counseling. This article, structured around the five stages in Super's life stage model and narrated in the language of vocational development tasks that he identified and researched, tells the story of Super's own career development and extrapolates the major themes in his unparalleled career as a vocational psychologist and career counselor.  相似文献

Measuring the impact of potentially controllable factors on the willingness of youth to undertake health risks is important to informed public health policy decisions. Typically the only data linking these factors with risk-taking behavior are retrospective. This study demonstrates, by means of a recent example, that there can be serious pitfalls in using even longitudinal retrospective data to draw conclusions about causal relations between potentially controllable factors and risk-taking behavior.  相似文献

One of Super's most important contributions has been in explicating those developmental tasks that involve planning, exploring, and deciding, processes known collectively as readiness for career choices. The authors review existing means of conceptualizing and operationalizing the various aspects of readiness, as well as innovative practice applications that have emerged from this work. Next, selected elaborations and extensions of the readiness construct are described. Finally, future directions for theory and research on readiness are presented with a particular emphasis on the promise of considering contextual issues, motivational factors, and an expanded measurement perspective in subsequent inquiry and practice.  相似文献

This paper contrasts economic and professional models of physician admitting behavior. Economic models emphasize physician convenience and income maximization, while professional models emphasize physician autonomy and independence. The paper examines the relative power of these models to explain two types of admitting decisions made by physicians: which hospitals to begin admitting patients to, and how many patients to admit to a hospital. Analyses of physician admitting patterns over a three-year period suggest that economic considerations outweigh professional considerations in both decisions. Results are interpreted in light of recent changes in the profession of medicine and physician-hospital relationships.  相似文献

HIV infection and homeless adolescents   总被引:1,自引:0,他引:1  
J L Athey 《Child welfare》1991,70(5):517-528
Homeless adolescents are at extremely high risk for acquiring HIV infection, as the literature reviewed in this paper documents. Sexual and drug use behaviors that put these adolescents at risk are described, and new models of service for these youths are outlined.  相似文献

It is sometimes argued that a relaxation of price controls in a regulated industry would lead to a decrease in profits and hence to an incentive for firms to skimp on safety. Theory does not allow us to sign the relationship between prices and safety a priori. Analysis of data from the railroad industry from 1963–67 indicates 1) profitable railroads have fewer accidents per mile than do unprofitable roads; 2) for profitable roads, if there is any relationship at all between accidents and profitability it is positive: more profitable roads have more accidents (per mile); and 3) for unprofitable roads, accident rates rise as losses rise.  相似文献

It has often been contended that the primary goal of policy modeling should be the insights quantitative models can provide, not the precise-looking projections—i.e. numbers—they can produce for any given scenario. Students of the energy policy process, in particular, have noted that preoccupation with the plethora of detailed quantitative results produced by large-scale computer models has substantially impeded their influence on key policy decisions. The creation of the Energy Modeling Forum (EMF) at Stanford University in 1976 represents one potential remedy for that situation. The EMF was formed to foster better communication between the builders and users of energy models in energy planning and policy analysis. The EMF operates through ad hoc working groups, composed of national and, more recently, international energy modeling and policy experts. These working groups conduct studies concentrating on a single energy topic. The diversity of backgrounds of the working group members ensures that the language of the EMF studies is English, not computer. Each working group identifies existing models relevant to the study's focus. A series of tests is then designed by the group to illuminate the models' basic structure and behavior. A comparison of results is published in a widely distributed report that identifies the models' strengths and weaknesses in the context of the study's topic. Seven EMF studies have been initiated to date: (1) Energy and the economy, (2) Coal in transition, (3) Electric load forecasting, (4) Aggregate elasticity of energy demand, (5) US oil and gas supply, (6) World oil and (7) Macroeconomic impacts of energy shocks. Each EMF study has broadened the understanding of the nature of the relevant policy issues and the models that have been, are, or could be used to address them. The present paper describes how each study's key insights were developed in the context of a simplified analytical framework that provided the proper perspective for understanding the model results.  相似文献

Intermarriage among heterogeneous social groups has often been studied as a process of assimilation. The present paper extends this research through a unique application of macro-structural propositions of intermarriage (Blau et al., 1982) to a nineteenth century American frontier population. Variants of these propositions are presented, used to address age patterns of nuptiality, and tested through a longitudinal application. Results support the utility of macro-structural theories in analyses encompassing initial community formation as well as assimilation of later arriving immigrants. Analyses illustrate both the assimilation of initially arriving immigrant groups on the frontier and the initial emergence of new heterogeneities in the established native population and later arriving immigrants.  相似文献

A brief introduction to Neuro-Linguistic Programming? (NLP?) as taught by the developers of NLP, Richard handler, John Grinder and their associates, is presented. This is followed by case examples. The cases illustrate what the authors believe are some of the substantive gains which NLP techniques have provided in their own and others' work with couples and families. NLP's major contributions involve understanding new models of human experience. This paper, however, is focused principally on a consideration of useful technology. The intent is to share from over three years' experiences certain fundamental and consistent benefits derived from the addition of NLP to clinical practice.  相似文献
