In this study, we explored the unique and common contributions of anxiety, self-esteem, and family communication on indecisiveness among adolescents. Three hundred and fifty pupils from 13 to 16 years of age completed self-report measures on indecisiveness, quality of family communication, trait anxiety, and self-esteem. The findings in this study showed that students’ indecisiveness is predicted by family communication mediated by anxiety and self-esteem. These results have important implications for practice as it stresses the importance of anxiety and self-esteem. Nevertheless, the counselors could also focus on enhancing relationship-building skills by introducing the adolescents’ career formation as an adolescent–parent joint project. 相似文献

ABSTRACTThe purpose of this study was to investigate the impact of older volunteers’ available human, social, and cultural capital on their motivational forces to volunteer, measured through the Volunteer Function Inventory. A large European database of 955 older volunteers (i.e., aged 50+) was employed, and Seemingly Unrelated Regressions showed that older volunteers have different motivations according to different sets of individual resources. Furthermore, lower amounts of human and social capital (e.g., low educational level, poor health, being widowed, divorced or single) are associated with a higher propensity to volunteer to enhance one’s own self-esteem, to avoid thinking of personal problems, and for social reasons. These results have important implications for policy makers and voluntary organizations if they want to enhance volunteering among older people with less resources, i.e., that are more at risk of social exclusion. For example, according to the results of this study, policy makers could consider developing more tailored opportunities for involving older volunteers with low educational level, poor health, widowed, divorced, or single. They could do this by underlying that volunteering offers possibilities to satisfy motivational needs important to the, elderly, e.g., to increase self-esteem, to deal with personal problems in a better way, and to have satisfying social contacts. 相似文献

This paper reports both procedures for the kinematic design and the results of dynamic analyses of three models of sit-ski
in order to evaluate their vibrational comfort. The model described in the US Patent US 6,019,380 has been assumed as a reference
in the following kinematic and dynamic analyses of the new models proposed. The two main features to be considered while designing
a sit-ski are the manoeuvrability and the range of vision of the driver. These two features appear to be important considering
that the sit-ski is generally used by disabled people (e.g. paraplegic). Thus the kinematic design phase should account for
the fulfillment of these requirements. On the basis of these, three new models have been proposed and herein named: Flex,
modified Flex and eight-bar linkage (Smarrini 2003). Once the kinematic synthesis and analysis have been completed the dynamic
performance of each model is investigated. For this purpose two kinds of slope profiles are simulated in order to reproduce
the stresses which may likely occur during a downhill race. In particular the position and the acceleration of the seat have
been monitored during the simulations. This is important in order to test the range of vision and handling requirements. The
seat acceleration is also important to evaluate the vibrational comfort of the sit-ski according to the British standard BS
6841 (Griffin 1990). The dynamic simulation is first executed by means of the multibody dynamics code NumDyn3D, then the vibrational
comfort analysis is performed using in-house developed software (Vita 2001, Valentini and Vita 2003). 相似文献

The use of outcome control modes of research evaluation exercises is ever more frequent. They are conceived as tools to stimulate increased levels of research productivity, and to guide choices in allocating components of government research budgets for publicly funded institutions. There are several contributions in the literature that compare the different methodological approaches that policy makers could adopt for these exercises, however the comparisons are limited to only a few disciplines. This work, examining the case of the whole of the “hard sciences” of the Italian academic system, makes a comparison between results obtained from peer review type of evaluations (as adopted by the Ministry of Universities and Research) and those possible from a bibliometric approach (as developed by the authors). The aim is to understand to what extent bibliometric methodology, which is noted as relatively inexpensive, time-saving and exhaustive, can complement and integrate peer review methodology in research evaluation. 相似文献

What are the conditions of the sales and purchases of translation rights in the Italian Market? The article summarizes and compares the results of two research studies conducted, respectively in 2003 and 2008 by the Italian Trade Commission as part of the initiatives planned in the Sector agreement stipulated among the Italian Ministry for Productive Activity, the Italian Publishing Association and the Italian Trade Commission. The objective is to optimize synergies between public and private activities in Italy in order to increase the export activity of the publishing industry sector. Both years the survey has been conducted by DOXA, a major Italian statistic research company. The researches focused on three fundamental variables: the geographical area in which a sales-purchases relationship is established, the genre of the books and the size of the companies involved by the phenomenon. 相似文献

It has become a common practice to include diagnostics and archaeometric studies during a masterpiece restoration. The advantages and limits of this approach are now topic of discussion in the community of researchers that is growing up quickly. The bronze burial monument of Pope Sixtus IV (1471–84) by Antonio del Pollaiolo, now in the Treasure Museum in the Vatican was intended to be located at the center of a chapel, this explains its apparent asymmetry: lack of height and large base. The restoration of the burial monument started in May 2007, it was carried out by first fulfilling a series of non-invasive analyses using a transportable EDXRF to map the composition of the alloy and evaluate the diagnostic capabilities for deterioration processes of the bronze surface. As a consequence of the first non-invasive diagnostic campaign, a second campaign of micro invasive tests was planned and carried out. The samples were analysed with SEM-EDS and XRF techniques. In this article some of the results of the EDXRF tests will be shown together with the procedures set up to maximize the diagnostic information obtained and minimize the need of microsampling from the artefact. The results and the statistical analysis of data show that a straightforward planning of the measurements can give several, sometimes unexpected, results in the definition of the state of conservation of the monument and also from an archaeometric point of view. With a high amount of data, the use of statistical analysis is necessary, for example in our case, the analysis of the variance confirmed the hypothesis of the use of different alloys for the elements of the panels. 相似文献

When a publication is cited it generates a benefit. Through the country affiliations of the citing authors, it is possible to work upwards, tracing the countries that benefit from results produced in a national research system. In this work we take the knowledge flow from Italy as an example. We develop a methodology for examination of how the knowledge flows vary across fields, in each beneficiary country. We also measure the field comparative advantage of countries in benefiting from Italian research. The results from this method can inform bilateral research collaboration policies. 相似文献

The development of scientometric indicators and methods for evaluative purposes, requires a multitude of assumptions, conventions, limitations, and caveats. Given this, we cannot permit ambiguities in the key concepts forming the basis of scientometric science itself, or research assessment exercises would rest on quicksand. This conceptual work attempts to spell out some principles leading to a clear definition of “impact” of research, and above all, of the appropriate scientometric indicator to measure it. The aim is to stimulate a discussion aimed at a definitive convergence on the meaning and measurement of a fundamental concept of the scientometric science. 相似文献

This paper presents an investigation of management accounting in four major Italian universities, which have been struggling
to build their strategy in a context of significant change. Following many OECD countries the Italian government has been
changing its higher education system by giving more autonomy to universities. These changes pose a number of challenges for
management and accounting systems in Italian Universities. Drawing on self-referential theory and its applications to accounting
research the paper analyses the construction of Strategic Management Accounting (SMA) in four Italian universities, which
are immersed in a similar context of change. The focus is specifically on two aspects of decisions: (1) resource allocation
and (2) new academic programme.
