Abstract In this study, we assessed the longitudinal effects of social-cognitive mechanisms on the self-reported use of doping substances and supplements among Italian high school students. In total, 1232 students completed questionnaires measuring various psychological factors hypothesized to influence students' intention to use substances. Three months later, 762 of the students completed the same questionnaires a second time and also reported their use of substances during the time between assessments. Overall, the percentages of students using doping substances (2.1%) or supplements (14.4%) were consistent with values reported in the literature. Analysis of the data showed that adolescents' intention to use doping substances increased with stronger attitudes about doping, stronger beliefs that significant others would approve of their use, a stronger conviction that doping use can be justified, and a lowered capacity to resist situational pressure or personal desires. In turn, stronger intentions and moral disengagement contributed to a greater use of doping substances during the previous 3 months. Doping use was also correlated significantly to supplementation. In conclusion, our results provide novel information about some of the psychological processes possibly regulating adolescents' use of doping substances and supplements. The results also highlight possible areas for future study and intervention, focusing on the prevention of adolescents' substance use. 相似文献

Self- and collective efficacy beliefs were examined as correlates of attitudes toward school of teachers, school staff, and
parents. 726 teachers, 387 staff members, and 1994 parents from 18 junior high schools in Milan and Rome, Italy, were administered
questionnaires assessing self-efficacy beliefs, perceptions about colleagues’ bahavior, collective efficacy beliefs, affective
commitment and job satisfaction of teachers and school staff and parents satisfaction with school.
Path analyses corroborated a conceptual model in which self- and collective efficacy beliefs represent, respectively, the
distal and proximal determinants of affective commitment and job satisfaction for teachers and staff and of satisfaction with
school for parents. Perceptions that teachers, staff and parents hold about the behavior of their colleagues largely mediated
the links between self- and collective efficacy beliefs. collective efficacy beliefs, in turn, largely mediated the influence
that self-efficacy beliefs and perceptions of school constituencies’ behaviors exert on attitudes toward school of teachers,
staff and parents. 相似文献

This paper examines the influence of departmental organization on faculty sentiments for social change via unionization. Two structural sources (inequalities of resources between departments; goal-rewarded discontinuities within departments) and one individual source (discontent with departmental governance) of attitudinal militancy are specified in path models and empirically examined using a sample of 338 faculty in 38 departments in a large, public university. Results lend limited support for inequalities of resources between departments as a source of militancy. Departmental discontinuities have important effects on the legitimacy of rewards, but only a weak indirect effect on militancy. Governance discontent has a strong impact on the legitimacy of rewards and an interesting indirect effect on militancy. 相似文献

The article presents a study on metalinguistic, cognitive and metacognitive abilities in university students. A sample of
353 students was recruited; 178 of which from scientific and 175 from humanistic Faculties, with gender balance (M = 178;
F = 175) whose age range was between 20 and 25 years old. They were administered a metalinguistic ability test that assesses
metalinguistic awareness at implicit and explicit levels (L and ML scores) and the Raven’s Standard Progressive Matrices 38
(SPM38). In addition to the usual nonverbal administration of the matrices, candidates were asked to justify in written form
the reasons for the solution indicated in each item. Three scores were considered for the SPM38: the ordinary score based
on the number of correct nonverbal solutions (O.S.), a 7-point scale for assessing the argumentation of the correct solutions
(C.ARG.S.) and a 6-point scale for assessing the argumentation of the incorrect solutions (I.ARG.S.). Significant gender and
curriculum effects were found, with males and scientific students dominating at the nonverbal level while females and humanistic
students dominated in the argumentative abilities related to the matrices and in all the scores of the metalinguistic test.
A number of significant correlations were found between all the metalinguistic, cognitive and metacognitive abilities considered,
with a prominent role of the metalinguistic abilities at the explicit level (ML score) that show a clear argumentative structure
very similar to the C.ARG.S. argumentations in the matrices test. 相似文献

The new Web generations are influencing the minds and changing the habits of software developers and end users. Users, librarians, and information services professionals can interact more efficiently, creating additional information and content and generating knowledge. This new scenario is also changing the behavior of information providers and users in health sciences libraries. This article reviews the new Web environments and tools that give librarians opportunities to tailor their services better, and gives some examples of the advantages and disadvantages for them and their users. Librarians need to adapt to the new mindset of users, linking new technologies, information, and people. 相似文献

Across the literature, travelling has been viewed as a recurring activity for older adults and is driven by a multitude of purposes and reasons. Previous studies have probed touristic activities of older adults however, little is known about their emotional experiences specifically their sense of happiness when joining international group tours, hence this phenomenological study. A qualitative approach was utilized to gather data from a group of 15 purposively selected participants aged 60 years and above. A two-part instrument consisting of a robotfoto and a semi-structured interview was used in this study. Through vertical and horizontal analyses of the field text, this study afforded the development of The Spiraling Model of Aging Filipino Tourists’ Happiness. This model describes aging tourists’ happiness while travelling as a product of Shared Moments, Shared Culture, Shared Memories, and Shared Transcendence. Summarily, findings of this study may provide significant insights to service providers such as hotels, airlines and travel agencies across the globe in developing innovative marketing strategies that cater to this promising age group. Empirically, this study may stimulate further exploration in the field of Cognitive Psychology aimed at adding large-scale data regarding the study of emotions specifically older adults’ happiness when joining international group tours. 相似文献

The purpose of this study was to analyse the raw lifting speed collected during four different resistance training exercises to assess the optimal sampling frequency. Eight physically active participants performed sets of Squat Jumps, Countermovement Jumps, Squats and Bench Presses at a maximal lifting speed. A linear encoder was used to measure the instantaneous speed at a 200 Hz sampling rate. Subsequently, the power spectrum of the signal was computed by evaluating its Discrete Fourier Transform. The sampling frequency needed to reconstruct the signals with an error of less than 0.1% was f99.9 = 11.615 ± 2.680 Hz for the exercise exhibiting the largest bandwidth, with the absolute highest individual value being 17.467 Hz. There was no difference between sets in any of the exercises. Using the closest integer sampling frequency value (25 Hz) yielded a reconstruction of the signal up to 99.975 ± 0.025% of its total in the worst case. In conclusion, a sampling rate of 25 Hz or above is more than adequate to record raw speed data and compute power during resistance training exercises, even under the most extreme circumstances during explosive exercises. Higher sampling frequencies provide no increase in the recording precision and may instead have adverse effects on the overall data quality. 相似文献

The present study examined the generalizability of the factor pattern, structural parameters, and latent structure of a multidimensional hierarchical model of ethnocultural empathy in males and females. The Scale of Ethnocultural Empathy (SEE) (Wang et al., 2003) was administered to a sample of 610 Italian undergraduates to examine the generalizability and reliability of its factor structure across gender, the psychometric properties and the validity of the scale. Two models were tested through multi-group confirmatory factor analysis (MGCFA): a confirmatory factor-analytic model that hypothesized a multidimensional model of ethnocultural empathy; and a structural equation model that proposed a multidimensional, hierarchical structure with global ethnocultural empathy as a superordinate construct that explained the covariances among the subdomains of the SEE. Both models satisfied multiple criteria for goodness-of-fit with the data. Full metric invariance of factor loadings and factor covariances, and partial invariance of error variances across gender for the four-factors model were supported. Scale reliability was also satisfactory, showing good internal consistency. As regard scale validity, evidence was found for a positive moderate association with a measure of general empathy and a negative high association with a measure of prejudice. Implications are discussed. 相似文献

Maintaining the microclimatic parameters at the desired value is essential for artefacts preservation. In order to control the status of the microclimatic parameters, a continuous monitoring of the indoor environmental provides conservators, curators, restorers, and lenders with an exact knowledge of the microclimatic conditions under which the works of art are kept. Moreover, the monitoring results give important information in order to make adequate changes to the control strategy of microclimatic parameters. From this point of view, monitoring is an essential tool to develop an actual preventive control programme aimed at maintaining the optimal microclimatic conditions for preservation. As a consequence, long-term monitoring has to be applied to prevent deterioration of works of art. The widespread opinion that a correct approach to the topic of microclimate control for artefacts preservation is not only and necessarily to provide buildings with sophisticated environmental control systems, but mainly to investigate the actual environmental dynamics and, before any structural intervention, to define the compatibility between the climate control potentials and the preservation requirements, has become more and more firm among the experts. Monitoring also allows to verify the capacity of the “building and Heating, Ventilation and Air Conditioning (HVAC)” system to maintain the desired thermo-hygrometric values within the operating conditions. To this aim, the Italian Standard UNI 10829 (1999) defining monitoring, elaboration and analysis of the microclimatic data as supporting actions for artefacts preservation, led to the need of a long-term monitoring and of a statistical approach to the data management. The approach proposed by the Italian Standard has been recently adopted by a European Standard (EN 15251, 2007). In accordance with the Standards mentioned above, in this paper an operational procedure to assess the thermo-hygrometric quality in museums is firstly synthetically presented and than applied to a case study. In particular, the procedure is developed in order to define the thermo-hygrometric quality level of the exhibition areas in the large museum complex of “Santa Maria della Scala” in Siena (Italy) during the international temporary exhibition “Duccio. La nascita della pittura senese” (“Duccio. The birth of Sienese Painting”). 相似文献
