抗战的严峻态势促使战时文艺工作者积极抛却成见,广泛汲取一切有益因子,借以最大程度地进行抗日宣传.于是通俗文艺也被纳入“抗战”叙事的洪流,并由此创生出崭新的“抗战通俗”类“变格”叙事.此类“变格”叙事不仅通过“叙事回避”达到了“叙事动员”的目的,而且更展现出了抗战文艺的多样风姿. 相似文献

This paper exploits the dramatic increase in house prices in early 2000 and the panel nature of the data to investigate the effect of home equity on charitable giving. Using the Panel Study of Income Dynamics from 2001 to 2007, we find that a 10% increase in home equity increases a household??s contributions to charity by almost 1%. This is in contrast to the effect of non-housing wealth, which we estimate to be one tenth the magnitude. Our results are consistent with the consumption literature that reports a distinct effect of housing wealth that is significantly larger than that of financial wealth. 相似文献

In recent decades the treatment of schizophrenia has focused primarily on pharmacotherapy with an emphasis on respite for family caregivers, support groups, and compliance regimens to sustain and maintain the affected client and family members. The use of family therapy models to intervene effectively with families affected by a diagnosis of schizophrenia is less common in the professional literature. This case study draws on the Mental Research Institute's communication theory and Bowen Family Systems Theory in therapeutic work with a Korean family. 相似文献

In semiconductor manufacturing, wafer fabrication is the most complicated and important process, and is composed of several hundred process steps and involves several hundred machines. The productivity of the manufacturing process depends mainly on controlling the balance of WIP (work-inprogress) flow to achieve maximum throughput under short manufacturing cycle times. This paper discusses how to determine the proper WIP level for operations, against which balance status can be measured. Balance measurement can be applied in mathematical modelling for bottleneck scheduling and operations management of the fabrication line. Performances are evaluated through computational experiments to show that balance driven management leads to 15-33% more production in 21% shorter manufacturing cycle time than production driven management. 相似文献

Using data from a 2007 national survey of working Americans, we examine the association between economic hardship and family-to-work
conflict (FWC). We also assess contingencies of this association, focusing particularly on gender and several work conditions.
Findings indicate that economic hardship is associated with higher FWC; this pattern is stronger among men. Three work conditions
also function as effect modifiers: The positive association between hardship and FWC is stronger for workers with less job
authority and more creative work activities. Job pressures also modify this association, but overall, respondents with higher
pressures report greater FWC. We discuss how our observations contribute to knowledge about the links between economic conditions
and the family–work interface and the importance of status and work-related contingencies. 相似文献

This paper uses a field survey to investigate the quality of individuals’ beliefs of relative performance in tournaments.
We consider two field settings, poker and chess, which differ in the degree to which luck is a factor and also in the information
that players have about the ability of the competition. We find that poker players’ forecasts of relative performance are
random guesses with an overestimation bias. Chess players also overestimate their relative performance but make informed guesses.
We find support for the “unskilled and unaware hypothesis” in chess: high-skilled chess players make better forecasts than
low-skilled chess players. Finally, we find that chess players’ forecasts of relative performance are not efficient. 相似文献

AbstractIn complex manufacturing environments, Cycle Time (CT) reductions obtained at critical production steps could generate considerable productivity improvements and lead to capacity increases at no investment costs. A wet-etch station operating in a real semiconductor manufacturing plant has been modelled to investigate the impact of different assignment strategies on CT performance. Assignment strategies based on the “Earliest Finish” (EF) concept have been developed and their productivity efficiency compared with a workload balance-based strategy. The EF-based strategies differ from each other for both computational complexity and amount of real-time information required. Encouraging results obtained for a high detail level EF strategy have inspired the development of conceptually similar strategies characterised by reduced implementation efforts. Fundamental implementation constraints, suggested by the manufacturing engineers familiar with the wet-etch station, have been taken into account throughout the different stages of this study. CT reductions ranging between 11% and 28% could be achieved at the modelled wet-etch station. 相似文献

The sample linear discriminant function (LDF) is known to perform poorly when the number of features p is large relative to the size of the training samples, A simple and rarely applied alternative to the sample LDF is the sample Euclidean distance classifier (EDC). Raudys and Pikelis (1980) have compared the sample LDF with three other discriminant functions, including thesample EDC, when classifying individuals from two spherical normal populations. They have concluded that the sample EDC outperforms the sample LDF when p is large relative to the training sample size. This paper derives conditions for which the two classifiers are equivalent when all parameters are known and employs a Monte Carlo simulation to compare the sample EDC with the sample LDF no only for the spherical normal case but also for several nonspherical parameter configurations. Fo many practical situations, the sample EDC performs as well as or superior to the sample LDF, even for nonspherical covariance configurations. 相似文献

Quality Assurance in Social Work Education: A Comparison of Outcome Assessments across the Continuum
Grafton H. Hull Jr. Jannah Hurn Mather Patricia M. Christopherson Charles M. Young 《Journal of Social Work Education》2013,49(3):388-396
Abstract Although assessing program outcomes has become increasingly important in higher education, no systematic research has been undertaken to determine the outcome measurement systems used across the entire continuum of social work education. This study, based on a 1992 survey of more than 150 baccalaureate, master's, and doctoral social work education programs, is the first to provide substantive data about the types of assessment systems in place at all three levels. It describes the frequency of use of various systems, makes comparisons across the levels of education, and discusses the implications for social work education at each level. 相似文献
