Mark J. Miller Nancy P. Newell Thomas P. Springer Don Wells 《The Career development quarterly》1992,40(4):334-339
The Self-Directed Search was administered to 68 university seniors who were majoring in Chemistry/Chemical Engineering, Elementary Education, and Office Administration. Their resulting three-letter summary codes were compared with three-letter college major codes obtained from the College Majors Finder. A high degree of agreement between the two sets of codes was found for each of the three majors. Effective methods for matching people to jobs have held the interest and occupied much time for career counselors and vocational theorists since the inception of the trait-factor approach to career counseling. More recently, Holland (1985a) broadened and clarified matching procedures through the development of his typological theory of vocational choice. Just as personality types and occupational environments have been organized using Holland's framework to foster an understanding of occupational choice, Holland's theory can also be used to explain other types of choices, such as choice of a college major. 相似文献

Parental choice of school is one of the main platforms of government education policy and is the centre piece of the Parents Charter. But sociological understanding of choice and choice-making is woefully underdeveloped. This paper draws on an ESRC study of market forces in education to explore social class variations in choice of school in one specific locality. The complexity of choice-making is portrayed using data from interviews with parents and it is argued that middle-class parents are taking full advantage of ‘the market’ to sustain or re-assert their class advantages. 相似文献

This paper compares legal approaches to foundations in six economically well-developed democracies (USA, England and Wales,
Germany, Austria, France and the Netherlands). ‘Foundations’ refers to ‘non-governmental, non-membership, organisations, recognised
as a legal category with a purpose in the general interest’. This covers the common field of the common law's charity and
the civil law's foundation as a legal person. The countries organise public supervision of foundations in very different ways.
Mostly there is governmental involvement or involvement of an independent body in the establishment and governmental supervision
of foundations in action. In a few cases, the supervisory power—concerning the foundations' activities, not their establishment—is
with judicial authorities. Access to information of foundations (registration) and possible requests for sanctions by interested
parties are also rather different. Not all rules are in accordance with the freedom of organisation and some are less desirable.
The conclusion is that a balance between the freedom of the foundation (board), the protection of the public order and the
protection of the interests of others can be found in a system with systematic supervision at the establishment- and later
practice—by governmental or independent authorities or in a system with good registration and incidental supervision by judicial
authorities, also at the request of interested parties. Both have their advantages and disadvantages. 相似文献

Susan J. Kelley 《Child Abuse Review》1994,3(1):15-25
While day care sexual abuse cases share features in common with sexual abuse in other settings, many characteristics of abuse in day care settings merit special attention. These factors include the young age of the child victims, the involvement of multiple victims and multiple perpetrators, females as perpetrators, use of extreme threats, severity of the abuse, and in some instances ritualistic activities. Research findings support clinical impressions that children are negatively impacted by sexual abuse in day care. Consequences of abuse in day care include anxiety, excessive fearfulness, behavioural disturbances, sexual acting out and sleep disorders. Parents whose children are abused in day care centres also experience psychological distress with symptom profiles consistent with post-traumatic stress disorder. Abuse of children in day care settings warrants a specialized treatment approach. A major goal of treatment is to decrease symptomatology among all family members. 相似文献

Each individual wage rate set by Davis-Bacon or by any similar state or local prevailing wage determination petrifies the
outcome of competing views of how construction work should be staffed and paid on public works projects. Although presented
with great precision (to tenths of a cent for both wages and fringe benefits), the level of wages themselves are of surprisingly
little consequence: Those set at union levels soon rise, being automatically updated to new contracts and conditions; the
rest fast become obsolete in any rising market, because surveys to update them are rare. But in addition to setting wage levels,
determinations also delineate which jobs get to have rates set for them, and perhaps most critically, whether those delineated
are identified as union or notunion. Whatever pattern is found may remain in effect for years or even decades, influencing
which journeymen and laborers own what job tasks and who may perform what. Also, if a particular job happens to be set as
union, it may bring with it dozens or even hundreds of related special job categories, grades of sub-groups, fine distinctions
of fringe benefits, and complex divisions of geographic applicability based on local union jurisdictional areas. This study
uses determinations recently made in Pennsylvania as an example to examine the mechanics of the wage-setting process. I find
that, in addition to the endemic problems one might expect associated with a complex and partly judgmental process, every
step of finding and setting prevailing rates includes overwhelming deference on the part of government towards union views
and methods. It shows why unions representing less than 20 percent of the private construction work force consistently set
the parameters controlling most of public construction. It ends with some suggestions on how better surveys and determinations
could be made. 相似文献

Childhood parental loss and adult depression 总被引:2,自引:0,他引:2
J D McLeod 《Journal of health and social behavior》1991,32(3):205-220
Previous research demonstrates convincingly that childhood parental deaths and parental divorces have implications for adult well-being as defined by levels of depression, educational attainment, early age at marriage, and risk of divorce. What this research has failed to examine are the interconnections among these outcomes. Specifically, are the socioeconomic and marital outcomes of parental loss implicated in the observed higher levels of depression? This analysis takes a first step in answering this question. Using data from a sample of 1,755 married men and women, I estimated regression models which examine the extent to which adult socioeconomic status and current marital quality mediate and/or modify the loss-depression relationship. Parental divorce was strongly related to socioeconomic and marital outcomes. Furthermore, current marital quality contributed importantly to understanding the higher levels of depressed mood observed among persons from divorced homes. Parental death was much more weakly related to socioeconomic and marital outcomes, and these outcomes played little role in explaining its relationship to depression. Finally, all of these relationships were stronger among women than men. These findings support the utility of life-course approaches to understanding adult mental health. 相似文献

Although Native Americans are plagued by high rates of alcoholism, violence, suicide and early death, these social and clinical problems are usually given little more than cursory treatment in textbooks. A content analysis of twenty-six textbooks on alcoholism and substance misuse revealed that only four provided a detailed discussion of Native American drinking. Greater attention needs to be given to the cultural, psychological, and biological issues of drinking and drunkenness among this special population. 相似文献

Although concerns have frequently been raised recently regarding the quality of life of intercollegiate athletes, information is seldom available on which college and university administrators can base policy decisions. Particularly lacking are studies that provide administrators with assessments of their own athletics programs relative to athletics programs at other institutions. We describe here a method we used in conducting a comparative evaluation of the status of student-athletes at a large public university, involving comparisons of student-athletes at this university to student-athletes at a subset of the institutions that participated in the 1987–88 National Study of Intercollegiate Athletes. By utilizing existing data sets to construct comparison samples, relative assessments of the status of student-athletes at a given institution can be performed without the excessive costs of gathering data on student-athletes at comparison institutions. Techniques employed in data collection and analysis are discussed as well as the format of the report in which the findings of the study were presented. 相似文献

The present study was conducted to assess differences in the behavioral and demographic characteristics of snuff (dip) users as compared to users of chewing tobacco. High School football players (1116) were surveyed concerning their use and perceptions of smokeless tobacco. Adolescent athletes who tried smokeless tobacco were more likely to be white, to use cigarettes, alcohol, and cigars and to have family users than those who never tried. Initial use was highest before the age of fourteen years and was influenced by friends, curiosity and family. Dippers tended to initiate use because of friends, while chewers started because of family users. Users of both dip and chew started primarily because of curiosity. Users of both were more likely to consume greater amounts to alcohol and cigarettes and to smoke cigars and pipes. It appears that the longer smokeless tobacco is consumed, the more likely both dip and chew will be used. Users of smokeless tobacco for more than two years tended to consume more of the product each week, used it for more hours/day, initiated use at an earlier age, and used it more often at school and work than those using it for less than two years. Use of cigars/pipes, consumption of alcohol, and quantity of cigarette consumption increased significantly with longer duration of smokeless tobacco use. Intervention and prevention programs would be helped by understanding differences between users of various smokeless tobacco products and differences related to the duration of use. In addition, further analyses of smokeless tobacco users should study chewers, dippers, and users of both separately. 相似文献
