ABSTRACT Wage policies in France were substantially renewed in the 1980s; this renewal was reflected in two phenomena: profit-sharing and merit payment. Merit payment is analysed here in relation to the emergence of new forms of organization of production. The need for higher-skilled labour, the relative decline of execution work and Taylorism have led to the setting up of systems of individual assessment and a more coherent organization of internal labour markets. Thus, merit payment should be seen as a very different practice from piece work: rather, it is the first attempt to establish a system of payment which could serve as a basis for renewing the entire wage bargaining set-up. 相似文献

Mediation and moderation are two theories for refining and understanding a causal relationship. Empirical investigation of
mediators and moderators requires an integrated research design rather than the data analyses driven approach often seen in
the literature. This paper described the conceptual foundation, research design, data analysis, as well as inferences involved
in a mediation and/or moderation investigation in both experimental and non-experimental (i.e., correlational) contexts. The
essential distinctions between the investigation of mediators and moderators were summarized and juxtaposed in an example
of a causal relationship between test difficulty and test anxiety. In addition, the more elaborate models, moderated mediation
and mediated moderation, the use of structural equation models, and the problems with model misspecification were discussed
conceptually.

We provide experimental evidence on the effect of peer pressure on individual behavior. Specifically, we study the effect of being exposed to an observer in a public restroom on handwashing and urinal flushing behavior. Our estimates show that being exposed to an observer increases the probability of handwashing by 13 percentage points and the probability of urinal flushing by 15 percentage points. Given that handwashing and urinal flushing have social benefits that exceed individual benefits, our findings provide support for peer pressure as an additional way of addressing the social suboptimality arising from externalities.

The application of ergonomics in product design is essential to its accessibility and usability. The development of manual devices should be based on ergonomic principles. Effort perception analysis is an essential approach to understand the physical and subjective aspects of the interface. The objective of the present study was to analyze the effort perception during a simulated task with different door handles by Portuguese subjects of both genders and different ages. This transversal study agreed with ethical aspects. 180 subjects of both genders pertaining to three age groups have participated. Five door handles with different shapes were evaluated. A subjective numeric rating scale of 5 levels was used to evaluate the effort. For statistical analysis it was applied the Friedman non-parametric test. The results have showed no significant differences of effort perception in door handles "A" and "B"; "A" and "D"; and "D" and "C". Door handle "E" presented the lowest values of all. In general, there's an inverse relationship between the results of biomechanical studies and the effort perception of the same task activity. This shows that door handles design influence directly these two variables and can interfere in the accessibility and usability of these kinds of products. 相似文献

This study introduces the Satisfaction with Life Scale adapted for Children (SWLS-C) and presents psychometric findings regarding
its validation. The SWLS-C was adapted from the Satisfaction with Life Scale (SWLS; Diener et al. 1985), which is one of the most commonly used measures to assess satisfaction with life in adults. Three subject matter experts
adapted the SWLS by changing the wording of the item stem and response format in order to make it more understandable for
children. A stratified random sample of 1,233 students (48% girls) in grades 4–7 (mean age 11 years and 7 months) provided
data on the SWLS-C and measures of optimism, self-concept, self-efficacy, depression, emphatic concern, and perspective taking.
The SWLS-C demonstrated a unidimensional factor structure and high internal consistency. Furthermore, differential item functioning
and differential scale functioning analyses indicated that the SWLS-C measures satisfaction with life in the same way for
different groups of children (i.e., with regard to gender, first language learned at home—English vs. other language(s) than
English—and across different grades) at the item and at the scale level. Associations between scores on the SWLS-C and demographic
variables were statistically non-significant or of small effect size. In addition, the SWLS-C showed evidence of convergent
and discriminant validity in relation to the other measures. Our results indicate that the SWLS-C is a psychometrically sound
instrument that demonstrated evidence of construct validity for this age group. Limitations and future directions are discussed. 相似文献

The satisfaction with life scale (SWLS) is a widely accepted and widely used tool for measuring well-being. Although its potential
as a cross-cultural index is recognized, an introduction and systematic validation of the Hebrew version is needed. Thus,
the purpose of this study is: (1) to describe the process of developing the Hebrew version of the SWLS, and (2) to examine
its construct validity as well as its internal consistency. Four hundred and eighty seven working adults completed the following
self reported Hebrew language versions of the: (1) SWLS, (2) positive affect and negative affect scales (PANAS), and (3) the
self-rated health (SRH) scale. In addition, as way of gathering additional evidence of validity, the SWLS was completed by
proxy (i.e., each participant’s life partner or significant other). Confirmatory factor analysis supported a single-factor
structure with significant correlations between the SWLS and the rest of the measures—PANAS scores, the SRH scores as well
as the SWLS scores as measured by proxy. In addition, item-analysis supports the internal consistency of the scale. The Hebrew
version of the SWLS is a valid and reliable scale and can be utilized in the Israeli context. 相似文献

Objective: To ascertain if two commonly used health status measures could be successfully self-administered to a group of older men recruited from the community to volunteer for a clinical research project and to correlate responses to the health status questionnaire to testosterone levels. Methods: In a cross-sectional survey 93 men, age 70 or greater, responded to a random mailing to a suburban community. Sixty-eight men were eligible and 47 participated in the study. Two health status questionnaires, the Sickness Impact Profile (SIP) and the Short-form 36 (SF-36), were mailed to participants with instructions to complete the surveys on the same day and return them by mail. Blood samples were obtained for bioavailable and total testosterone measurements. Pearson correlation coefficient analysis was used to compare the responses to the SF-36 and SIP and testosterone levels. Results: Of the eligible volunteers 69% participated and were able to self-administer the SIP and the SF-36. Summation scores for the surveys were above those reported in similar age populations. Perfect scores were reported frequently in all subsets of the SIP; perfect scores were reported in 43-92% of men on various subscales. The responses to the SF-36 were also frequently perfect although perfect scores ranged from 2 to 82% on various subsets. There was moderate correlation between the results from the two surveys. There was no correlation between age, SIP or SF-36 and testosterone level. Conclusions: Healthy older men volunteering for clinical research were able to self-administer both the SIP and SF3-6. Responses to both surveys were skewed toward perfect scores; the SIP failed to reveal many men with functional deficits. Bioavailable testosterone levels did not predict perceived health in this group of men. 相似文献

Relative income differences are likely to lead to envy within a reference group. Envy in turn influences social behavior and individual performance. While positional concerns are apparent in daily life, empirical evidence is rare in the economic literature. This paper investigates the impact of the relative income position on individuals’ performance or productivity. As ?performance“ is difficult to measure we turn to soccer players whose performance has been well documented. The broad sample covers eight seasons of the German premier soccer league (Bundesliga) between 1995 and 2004, and includes 1040 players, a salary proxy and several performance variables. The results show that player performance is strongly affected by relative income position. A disadvantage in the relative income position reduces productivity. The larger the income differences within a team, the stronger are the effects of positional concern. Team composition also significantly affects behaviour. 相似文献
