The new product process comprises the set of activities that move the product from idea to launch. The authors investigated the new product process activities of firms in Australia, England and Belgium. Objectives of the research were to determine—what activities are undertaken in the new product process? How proficiently are these activities performed and what improvements are needed? whether the sorts of activities undertaken and their proficiency affect project success or failure. Since these activities are largely under the control of management, the deeper is our understanding of new product process activities, the greater the scope for improved product innovation management. 相似文献

Few studies have investigated whether parents’, teachers’ and children’s responses to the strengths and difficulties questionnaire (SDQ) have equivalence. In this study, data from 854 matched questionnaires collected in Malaysia were subjected to tau equivalence confirmatory factor analysis, to assess if all three groups responded to the same target (the child) similarly. We first fitted Goodman’s (Journal of Child Psychology and Psychiatry, 38, 581–586, (1997a); Journal of Child Psychology and Psychiatry, 40, 791–801, 1997b) five factor model, but found that this did not fit the model despite attempts to improve and rectify model fit. We thereafter attempted to fit Dickey and Blumberg (Journal of the American Academy of Child Adolescent Psychiatry, 43, 1159–1167, 2004) three factor model, but similarly found a lack of fit. We then undertook an exploratory model with a random half of the data, obtaining a three factor solution, and tested this in a confirmatory tau equivalence model. The Unconstrained Model provided a fit to the data, revealing a similar structure across the three informant groups. As this fit was for the Unconstrained Model, it reveals that groups differ in the value they place on each of the variables but overall that held a similar underlying factor structure. The findings are discussed in relation to the possible cultural issues involved and the use of the SDQ. 相似文献

Given aggregate time-series data, conventional Markov Chain estimation of the stationary transition probabilities is performed for a model of the cereal market in Great Britain. The possibility of non-stationary probabilities is examined in the light of these initial results, and the basic model developed to allow exogenous variables to enter via their influence on these parameters. The evidence from the paper would appear to suggest that, at least in the case considered, time-varying transition probabilities are a most attractive alternative. 相似文献

The purpose of the present study was to investigate the factor stability of the Children’s Attitudes and Behaviors Towards Animals Scale (CABTA) across two eastern contexts: China and Malaysia. Confirmatory factor analyses (CFAs) were conducted on data collected from 700 Chinese mothers and 700 Chinese fathers, and 385 Malay parents of children aged 6–12 years. The CFA results suggested that the model was a good fit for both the Chinese and Malaysian responses. Furthermore, invariance testing showed that although there was factor loading invariance across cultures, the assumption of intercept invariance did not hold. This suggests that although the scale is suitable for use in both cultures, mean comparisons across contexts could be problematic. The internal reliabilities for the Typical and Malicious cruelty subscales were adequate across the samples. All findings show that the CABTA is a promising scale for international use. 相似文献

Manufacturing continued to lose large numbers of jobs, and other industries had small employment declines; only services and government added substantially to their employment, but with weaker gains than in the 1980's. 相似文献

How noneconomic benefits claimed by labor unions relate to union interest is not well articulated. Based on Torres and Bergner’s (Journal of the American Academy of Psychiatry and the Law, 38, 195–204, 2010; Psychotherapy, 49, 492–501, 2012) analysis of severe public humiliation, in which status enhancement underlies recovery, we examined an augmented relationship between humiliation at work (the underside of dignity at work) and willingness to join a union. As hypothesized, nonunion employees who were less detached from work showed more willingness to join when presented with evidence that members of a union were satisfied with community aspects of membership related to status enhancement above and beyond their satisfaction with economic aspects. Implications for union interest research and applications are discussed. 相似文献

To aid American union practitioners in the selection of winnable worksites in unionization elections, we identified predictors of union interest from psychological perspectives that bear on the character of American workers. Using perceived union instrumentality as a standard to determine the prediction status of new psychological predictors of union interest, a cognitive version of self-enhancement (overconfidence in rating one??s skills and abilities) was found to predict interest above and beyond perceived instrumentality in a sample of American nonunion employees (N?=?452), controlling for social desirability, demographic and structural predictors, and other hypothesized predictors in a six-step hierarchical regression equation. Implications for selecting winnable election worksites and for predicting psychological aspects of union interest are discussed. 相似文献
