Underdeveloped theory about educational credentialing flies in the face of the immense practice of educational degree attainment by ever increasing proportions of each new generation, and the ensuing pervasive belief in the power of degrees to both allocate individuals in the labor market and to serve as job requirements throughout the occupational structure. Considering educational credentialing at the center of the educational revolution in postindustrial society, a new theoretical argument is developed from the premise that education as an institution provides the logic by which educational credentialing becomes evermore legitimate, more so than from forces outside the institution itself such as the economy and labor market demand. In support of the proposed theory of credentialing, multiple sets of new findings about education, occupations, and work show that the common negative notion of run-away educational credentialism does not fit empirical trends. Second, as a function of widely held beliefs about education in postindustrial society, four institutional processes by which educational credentialing has deeply integrated into the occupational structure are described and illustrated with empirical observations and analyses. Lastly, consequences of the rapid and robust educational transformation of occupational credentialing for future sociological inquiry into social stratification and mobility are discussed. 相似文献

The paper has two parts. In the first part we offer a definition of well-being which makes life expectancy an explicit variable.
We recognize the importance of happiness as a significant aspect of any definition of well-being, but we side-step the issue
of what determines its level or how to measure it, and concentrate instead on the consequences of our new variable, life expectancy.
We argue that life is valued for its quality, and, if positive, its extension is an improvement of well-being. From this we
show how, given certain assumptions, disparate problems that have moral and/or social significance can be approached from
the perspective of improving well-being. We close the first part by showing that our definition has enough flexibility to
be used for that class of decisions which require tradeoffs between quality of life (happiness) and life expectancy. As a
corollary we show that attitudes toward risk depend on expectations, and on some occasions, age itself. In the second part
we argue, first, that real economic factors, not reducible to mere psychological ones, may still offer an adequate explanation
for the fact that absolute income and happiness do not always correlate well. However, we take no position on the many controversies,
such as whether it is relative or absolute increases in wealth that bears most directly on changes in happiness. We confirm
through statistical analysis (simple regressions) the well established influence that absolute income has on life expectancy,
and, hence, by inference and definition, we argue that this must also be the case with well-being. Secondly, we find through
statistical analysis that healthcare has as much impact on life expectancy as does absolute income, leading us to theoretically
examine the appropriate income cost for access to healthcare if life expectancy is to improve. And thirdly, by assuming a
homogeneous function of life expectancy, we theoretically show how a market oriented healthcare system can exacerbate inequities
in life expectancy, and so on well-being. Lastly, we consider some policy implications of those inequities. 相似文献

In a recent Decision Sciences article, McMath (1990) developed the correction constants approach for eliminating the end-of-year bias in the present value of streams with subannual cash flows. A limitation of this approach is that it assumes subannual cash flows are level. In many types of businesses, subannual cash flows follow a predictable seasonal pattern and, consequently, a present value estimate based upon a level correction constant is biased. This article derives a general formula for determining correction constants for seasonal cash flow patterns, examines the direction and magnitude of the seasonal bias, and applies seasonal correction constants to a capital budgeting problem. 相似文献

In the past 15 years, research activities focusing on the interlinkages between climate change and human mobility have intensified. At the same time, an increasing number of actors and processes have sought to address human mobility in the context of climate change from a policy perspective. Hitherto, research has been limited in terms of geographical preferences as well as conceptual and methodological focus areas. This paper argues that to address the evolving policy space, future research on climate change in the context of human mobility needs to become more differentiated, integrated and generalized. This includes concerted efforts to better integrate researchers from the global South, improved cross-linkages between different datasets, approaches and disciplines, more longitudinal and comparative studies and development of innovative qualitative and quantitative methods. 相似文献
