We present a new multidimensional measure of sexual activity and preference that may be of use to researchers and practitioners who work in clinical settings involving sex‐related problems. The questionnaire contains six subscales to measure amounts of sexual activity and six subscales to measure degree of preference for those activities. The 12 subscales have good to excellent reliabilities, and they all appear to have content, construct, and factorial validity. 相似文献

A case study on the implementation of a just-in-time (JIT) production system by a Canadian manufacturer in the heavy machinery industry is presented. Many hurdles and difficulties were encountered during implementation and the way in which these problems were resolved is reported. While the successful implementation of a JIT system depends on a host of technical and human factors, this study suggests that the people involvement factor is the most crucial. It is seen that the key elements to securing people involvement are institution leadership, company-wide education and training and mutual understanding, trust and respect among employees. The moral of this study is that without employee involvement nothing will happen and no result will be achieved. 相似文献

This paper deals with modeling firm-specific technical change (TC), and technological biases (inputs and scale) in estimating total factor productivity (TFP) growth. Several dual parametric econometric models are used for this purpose. We examine robustness of TFP growth and TC among competing models. These models include the traditional time trend (TT) model and the general index (GI) model. The TT and the GI models are generalized to accommodate firm-specific TC and technological bias (in inputs and output). Both nested and non-nested tests are used to select the appropriate models. Firm-level panel data from the Japanese chemical industry during 1968- 1987 is used as an application. 相似文献

In performance evaluations, data without explicit inputs (such as index data, pure output data) are widely used. To directly use such data, this paper presents a study on building DEA models without explicit inputs, so-called DEA-WEI models, which are applicable to the evaluation applications where inputs are not directly considered. We provide an axiom foundation of these kinds of models, and further discuss how to incorporate value judgments of decision makers into these DEA-WEI models. Several such models are derived. Finally, applications of the DEA-WEI models are presented. 相似文献

We examined factors related to attitudes toward marriage and the importance of having children in both the US and Singapore.
Path analysis indicated that life dissatisfaction leads to materialism, and both of these factors lead to favorable attitudes
toward marriage, which leads to greater desire for children. Further analysis indicated this model was effective in explaining
the difference in desire for children between Singaporeans and Americans, whereby Singaporeans have lower life satisfaction,
higher materialism, and lower attitudes toward marriage and children. Materialistic standards of success were also related
to the emphasis women placed on potential marriage partners’ earning capacity. As Singaporean women had higher materialistic
standards, they also placed higher emphasis on potential mates’ earning capacity. Results suggest a consideration of psychological
variables such as life satisfaction, materialism, and mate preferences may lead to a better understanding of larger-scale
socioeconomic issues, including low fertility rates among developed East Asian countries. 相似文献

This paper considers five test statistics for comparing the recovery of a rapid growth‐based enumeration test with respect to the compendial microbiological method using a specific nonserial dilution experiment. The finite sample distributions of these test statistics are unknown, because they are functions of correlated count data. A simulation study is conducted to investigate the type I and type II error rates. For a balanced experimental design, the likelihood ratio test and the main effects analysis of variance (ANOVA) test for microbiological methods demonstrated nominal values for the type I error rate and provided the highest power compared with a test on weighted averages and two other ANOVA tests. The likelihood ratio test is preferred because it can also be used for unbalanced designs. It is demonstrated that an increase in power can only be achieved by an increase in the spiked number of organisms used in the experiment. The power is surprisingly not affected by the number of dilutions or the number of test samples. A real case study is provided to illustrate the theory. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献

Creative endeavors often resemble one another. This paper explores similarities between sociology and art based on the use
of conventions and creativity. More specifically, by comparing the construction of musical mix tapes, the author draws parallels
between creating sociology and mix tapes. Looking at the process of how a mix tape is created using other artists’ songs and
music for a specified purpose illuminates sociology and our roles as sociologists in a new light that leaves open new possibilities. 相似文献
