This article illustrates the differences in knowledge about HIV and AIDS and attitudes among 150 young women from three different countries (Sweden, Chile and Ecuador). In each country, 50 consecutive women, visiting a family planning clinic answered 23 structured questions. The questionnaire was translated into Spanish. The aim of this study was to evaluate the influence of age, education, ethnicity and religion on young women's knowledge of HIV and AIDS. This study shows that ethnicity is the most important independent variable influencing the level of knowledge (stepwise logistic regression). Also, in Chile and Ecuador, less than 10% of the women in the study required that their partner use a condom. In Sweden the use of condoms is often combined with another contraceptive, yet more than two thirds of the women in Sweden were unprotected from a sexually transmitted disease during coitus. 相似文献

Studies have indicated that the number and frequency of fraudulent publications being retracted are not subsiding even with greater awareness of such incidents in the recent decades. In this study, the trends of retraction period, number of citations and coauthors of 5 selected researchers who had ≥ 15 fraudulent publications retracted were analyzed. The obtained results shows that the retraction period is 48.96 ± 32.16 months for the 113 publications affiliated to the 5 studied researchers. There are a total of 180 coauthors with 6.40 ± 3.26 coauthors per researcher's retracted publication. The linear regression analysis indicates that there is limited correlation (R2 = .008) between the citation counts and retraction period. The p value for multiple F-tests to assess the number of coauthors to a fraudulent publication on an interresearcher basis is found to be ranging from < .001 to .458. It is also found that a better correlation (R2 = .592) exists between the likelihood of a researcher to involve different individuals for isolated fraudulent publications while only selecting very few to be their frequent coauthors of their mischievous acts. With this study, the possible use of coauthors as a strategy for publishing fraudulent work and a potential approach to tighten coauthorship are discussed. 相似文献

Psychometric Validation of the Gambling Passion Scale (GPS) in an English-speaking University Sample

The Gambling Passion Scale (GPS) is a recently developed research instrument for assessing individuals' passion for gambling. Because the psychometric properties of the GPS have only previously been examined in French Canadians, the aim of this study was to replicate previous psychometric findings in an English-speaking university sample. Participants (female: n = 58; male: n = 89) were drawn from a university campus based on self-reported experience with gambling indexed by scores on the South Oaks Gambling Screen (SOGS). The two-factor structure reported by Rousseau et al. (Journal of Gambling Studies, 18(1), pp. 45–66, 2002) was largely replicated in this sample, as were relationships between ‘obsessive passion’ and negative consequences stemming from gambling. These results support the validity of the GPS as a measure of gambling passion in English-speaking university gamblers and its potential to contribute to understanding problem gambling. 相似文献

There is considerable evidence that inflation variability and the level of inflation are positively related across countries. Evidence of a within-country relation is mixed. Evidence for a significant positive relation comes mostly from studies using some survey measure; contrary evidence comes mostly from studies using regression errors. Our measure of uncertainty is the squared forecast-error from Organization for Economic Cooperation and Development inflation forecasts. Most countries do not exhibit a positive and significant relation. The greatest number of positive coefficients is for relative uncertainty regressed on contemporaneous inflation. 相似文献

The present study assessed the divergent validity of several self-report and objective behavioral measures for assessing pathological gambling using three samples divided by South Oaks Gambling Scale score [Lesieur, & Blume (1987). American Journal of Psychiatry, 144, 1184–1188]: pathological gamblers, potential pathological gamblers, and non-pathological gamblers. Self-report measures included the Gamblers’ Beliefs Questionnaire [GBQ; Steenbergh, Meyers, May, & Whelan (2002). Psychology of Addictive Behaviors, 16, 143–149], the Gambling Passion Scale [GPS; Rousseau, Vallerand, Ratelle, Mageau, & Provencher, (2002). Journal of Gambling Studies, 18, 45–66], the Eysenck Impulsivity Questionnaire [EIQ; Eysenck, & Eysenck (1978). Psychological Reports, 43, 1247–1255], and the Stanford Time Perspective Inventory [STPI; Zimbardo, & Boyd (1999). Journal of Personality and Social Psychology, 77, 1271–1288]. Behavioral tasks included the delay discounting task [Madden, Petry, Badger, & Bickel (1997). Experimental & Clinical Psychopharmacology, 5, 256–263] and the Future Time Perspectives [FTP; Wallace (1956). Journal of Abnormal Psychology, 52, 240–245]. The GBQ, GPS, Impulsivity subscale of the EIQ, and DDT all exhibited robust divergent validity, however, neither measure of time perspective discriminated between groups. Applications of these findings to etiological research and clinical contexts are discussed.This work was originally presented in November, 2003 at the 37th annual convention of the Association for the Advancement of Behavior Therapy in Boston, MA. 相似文献

Many new products and substitute technologies fail because they enter markets too late or with too little price/performance advantage. Essentially, these products have missed their window for successful market entry. To avoid this type of product entry error, management should locate and define the boundaries of the strategic entry window for their products or technologies. 相似文献

This paper explores theoretical and practical aspects (i.e. resources allocated, activities undertaken, actors/decisions involved) of corporate 'parenting' in the development of international service networks. A review of the relevant corporate strategy, supply-chain, networks and services management literature underpins a preliminary content (capability; market orientation) and process (top-down; bottom-up) typology of network parenting. This provides the structure for discussion of two telecommunications-sector case studies. Analysis of the data acknowledges the influence of generic network mechanisms (e.g. weak and strong social ties) but the parenting typology also highlights other mechanisms, the effectiveness of which appears contingent on specific parenting roles. The paper details these roles (labelled: governing; training; curating; facilitating) and makes some preliminary comments on the role trajectories (e.g. governing ↔ training) observed. The paper concludes with a discussion of possible directions for future work. 相似文献
