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

Argumentative abilities in metacognition and in metalinguistics: a study on university students     

Maria Antonietta Pinto  Paolo Iliceto  Sergio Melogno 《European Journal of Psychology of Education - EJPE》2012,27(1):35-58

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   

How the New Web Generations are Changing Library and Information Services     

Giovanna F. Miranda  Francesca Gualtieri  Paolo Coccia 《Medical reference services quarterly》2013,32(2):132-145

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   

Who says aging is lonely? A phenomenology of Filipino older adults’ experiences of happiness when joining international group tours

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   

Surface cleaning? Yes,freshly grated Agar gel,please     

Paolo Cremonesi 《文物保护研究》2016,61(6):362-367

Polysaccharide-based rigid hydrogels are by now well-established means for delivering water or, more generally an aqueous solution, to a surface in a controllable way so as to minimize diffusion and possible side-effects on water-sensitive materials during cleaning treatments. These gels can be applied as pre-formed solid bricks on planar surfaces or brushed onto objects in a semi-solid state. In this note, a different application procedure is presented, suitable for surface cleaning treatments of sensitive painted surfaces: pre-formed rigid gels grated to tiny particles that can be brushed onto the surface. A general discussion on the strategies that can be adopted when water is required to clean a water-sensitive soiled surface is presented, then the new procedure is discussed and a representative case study is shown, supporting the procedure described.  相似文献   

Effects of strength,explosive and plyometric training on energy cost of running in ultra-endurance athletes     

Nicola Giovanelli  Paolo Taboga  Enrico Rejc  Stefano Lazzer 《European Journal of Sport Science》2017,17(7):805-813

The aim of the present study was to evaluate the effects of a 12-week home-based strength, explosive and plyometric (SEP) training on the cost of running (Cr) in well-trained ultra-marathoners and to assess the main mechanical parameters affecting changes in Cr. Twenty-five male runners (38.2?±?7.1 years; body mass index: 23.0?±?1.1?kg·m^?2; V˙O₂max: 55.4?±?4.0 mlO₂·kg^?1·min^?1) were divided into an exercise (EG?=?13) and control group (CG?=?12). Before and after a 12-week SEP training, Cr, spring-mass model parameters at four speeds (8, 10, 12, 14?km·h^?1) were calculated and maximal muscle power (MMP) of the lower limbs was measured. In EG, Cr decreased significantly (p?<?.05) at all tested running speeds (?6.4?±?6.5% at 8?km·h^?1; ?3.5?±?5.3% at 10?km·h^?1; ?4.0?±?5.5% at 12?km·h^?1; ?3.2?±?4.5% at 14?km·h^?1), contact time (t_c) increased at 8, 10 and 12?km·h^?1 by mean +4.4?±?0.1% and t_a decreased by ?25.6?±?0.1% at 8?km·h^?1 (p?<?.05). Further, inverse relationships between changes in Cr and MMP at 10 (p?=?.013; r?=??0.67) and 12?km·h^?1 (p?<?.001; r?=??0.86) were shown. Conversely, no differences were detected in the CG in any of the studied parameters. Thus, 12-week SEP training programme lower the Cr in well-trained ultra-marathoners at submaximal speeds. Increased t_c and an inverse relationship between changes in Cr and changes in MMP could be in part explain the decreased Cr. Thus, adding at least three sessions per week of SEP exercises in the normal endurance-training programme may decrease the Cr.  相似文献

The “Medico-Pedagogical Institutes” and the failure of the collaboration between psychiatry and pedagogy (1889–1978)     

Paolo Bianchini 《Paedagogica Historica: International Journal of the History of Education》2019,55(3):511-527

ABSTRACT

In the late nineteenth and early twentieth century, a number of Italian psychiatrists were convinced that medicine and education should work together to treat children with mental disabilities, then commonly defined as “feeble-minded”. To this end they promoted the establishment of “Medico-Pedagogical Institutes”, institutes, that is, with medical and psychological staff, reserved for disabled minors considered “amendable” or “educable”. These institutions were to serve, on the one hand, to remove children from Mental Hospitals, and on the other, to enable them to be educated and to improve their psycho-physical attitudes. Nevertheless, over their long history, which lasted about a hundred years, the educational component decreased significantly and many Medico-Pedagogical Institutes ended up by resembling adult Mental Hospitals. At the end of the 1970s, several scandals erupted, revealing the inhuman conditions in which children were treated, and all the Institutes were closed. It is impossible to understand the overall sense of the value and the functions exercised by the Medico-Pedagogical Institutes over the century of their existence, unless we take a long-term perspective, which can help to create a detached and balanced history, revealing of our relationship with diversity and biopower.  相似文献
