Do Costs Differ Between For-Profit and Not-for-Profit Producers of Higher Education? 总被引:1,自引:0,他引:1
In theory, not-for-profit organizations will be characterized by higher production costs per unit of output than for-profit producers of otherwise-identical goods/services, since profit maximization implies cost minimization per unit of output; breaking even does not imply cost minimization and, indeed, may imply inflated costs. We explore the empirical validity of this hypothesis in the context of higher education. Using 1996 data, we estimate multiproduct cost functions for 1,450 public, 1,316 private, not-for-profit, and 176 private, for-profit institutions of higher education in the United States. We fail to find a statistically significant difference between for-profit and not-for-profit private providers, but do find a statistically significant difference between private, not-for-profit institutions and public institutions. 相似文献

Abstract Microcomputer aided instruction often provides pupils with a means of obtaining assistance. The findings of an initial study suggested that experience on a microcomputer task with a help facility does not necessarily lead to improved performance. The frequent use of a help facility was associated with poorer concurrent performance and was associated with poorer performance when the help facility was no longer available. The possibility that the effects of the help facility were confounded by other variables led to a second controlled investigation of this issue. This experiment confirmed that a help facility was of no significant benefit and appeared to interfere with some aspects of the pupils’ performance. The initial investigation also examined other sources of influence on computer‐based problem solving. It was found that, as predicted, pupils with an intrinsic orientation tended to use a help facility less and to choose more difficult problems. However, pupils who were intrinsically orientated were not found to be any better at computer‐based problem solving than pupils who were less intrinsically orientated. Finally, no differences were found in computer‐based problem solving according to gender or the pupils’ access to home computers. 相似文献

This paper attempts a theoretically based articulation of the concept of legitimacy and applies the elements of the concept to concrete problems in university governance. Legitimacy is measured by the assessment of several elements of governance by constituents. It is a function of constituents' value systems, of the decision-making issue, and of the level at which decisions are made. The components of legitimacy are developed, and illustrative applications are provided. Through operational application of the idea of political legitimacy, it is contended that more realistic and workable solutions to governance can be approximated and that crisis oriented governance tactics can be reserved for situations which genuinely require them. 相似文献

To enhance employability and improve the career prospects of graduating students, this study explores the influence of practical experience on graduate employment outcomes in an Australian setting. To develop our understanding of the relative benefit of different forms of practical experience, the study evaluates the influence of both Work-Integrated Learning (WIL) and paid work in the final year of study on graduate employment and underemployment. Two samples are used, N?=?628 and N?=?237, to evaluate institutional data on practical experience combined with national data on graduate employment outcomes. Findings indicate that participating in WIL does not produce an increase in full-time employment rates. There is some evidence to suggest that it could lead to higher quality, relevant employment in both the short and long term. Paid employment during the final year of undergraduate study produced higher full-time employment rates, but had little effect on underemployment. Findings will help to inform stakeholders of the relative benefit of curricular and extra-curricular work experience and contribute to the dearth of empirical evidence on the value of activities designed to improve graduate employment prospects. This is particularly important given growth in the supply of graduates, concerns for credentialism, soft graduate labour markets and global economic weakening. 相似文献

This paper uses data from the Scottish School Leavers Surveys to investigate trends in the transition from school at a time of deepening recession. The main change observed is the collapse of employment between 1979 and 1983. The paper also describes trends in the distribution of school‐leaver employment, in its industrial and occupational composition, in patterns of movement in the youth labour market and in the role of special programmes. Some of its general conclusions challenge ideas current among some British sociologists. First, youth unemployment (at least among recent school leavers) is no longer significantly connected with patterns of subemployment or frequent job‐changing. Secondly, unemployment has not fundamentally changed the ‘selective function’ of education; credentials have retained their labour‐market value in relative if not in absolute terms. Thirdly, the recent rise in school‐leaver unemployment is very largely a result of the recession—the decline in the aggregate demand for labour—rather than of underlying structural changes that disadvantage young people; most recent changes in the transition from school to work are in principle reversible if the recession ends. The paper assesses the implications of these findings for the sociology of education, and concludes with a discussion of the possible impact of the Youth Training Scheme. 相似文献
