Optimism has been classically considered a key trait in entrepreneurs' personality but it has been studied from a psychological point of view only in recent years. The main aim of this research is to study the relationship between dispositional optimism, pessimism and realism as a function of the tendency to create technology-based businesses. A sample of undergraduate students (n= 205) filled in an electronic questionnaire containing the Life Orientation Test-Revised after they were classified as potential technological entrepreneurs, potential general entrepreneurs and non-potential entrepreneurs. Our results show that technology-based entrepreneurs are more optimistic than non-potential entrepreneurs, whereas there were no statistical differences in pessimism and realism. The results are interpreted theoretically to define the potential entrepreneur and, from an applied perspective, to design training programmes to support future technological entrepreneurs. 相似文献
There is a general consensus that HFE- related Hereditary Haemochromatosis (HFE-HH) should be diagnosed at early stages in pre-symptomatic individuals, in order to prevent the most severe consequences of iron overload. In Portugal, despite an increasing number of requests for genetic diagnosis of this rare disease, there is not a corresponding increase in requests for genetic counselling. The objective of the present study was to evaluate physicians’ main motivations for requesting HFE genotyping or genetic counselling for HFE-HH. We assessed current medical practices regarding family testing and diagnosis and discuss whether these can be improved in order to increase the effectiveness of disease prevention. Our results show there is a general lack of knowledge about the selection of patient cases that should be sent for genetic counseling or for molecular testing of HFE-HH by physicians (especially by general practitioners). The lack of family-based screening may indirectly compromise the efficiency of disease prevention in terms of early diagnosis and treatment. We concluded it is necessary to circulate more information about Hereditary Haemochromatosis among health professionals in order to improve strategies for its early diagnosis. 相似文献
Existing psychological research has long considered humor as a useful strategy for individuals in coping with adverse circumstances and life stressors. However, empirical studies are called for to better understand the role of humor in facing the COVID-19 pandemic. In a community sample of 527 Spanish adults, we investigated the associations between humor styles, perceived threat from COVID-19, funniness of COVID-19 memes, and individuals’ affective mood. Data were collected during the third week of lockdown in Spain (from 26 to 31 March 2020). Our results suggest that intrapsychic humor styles were associated with better coping with the COVID-19 pandemic. Structural equation modelling showed that self-enhancing and aggressive humor styles were related to perceiving COVID-19 as less psychologically threatening, which, in turn, was associated with a greater perceived funniness of COVID-19 memes, thus predicting higher levels of happiness. Interestingly, the opposite pattern of connections was found for self-defeating humor. These findings suggest that humor styles aimed at boosting one’s own self, irrespective of their potentially lighter or darker nature, may contribute to alleviating adverse psychological consequences arising from the COVID-19 pandemic.
Value added is a common tool in educational research on effectiveness. It is often modeled as a (prediction of a) random effect in a specific hierarchical linear model. This paper shows that this modeling strategy is not valid when endogeneity is present. Endogeneity stems, for instance, from a correlation between the random effect in the hierarchical model and some of its covariates. This paper shows that this phenomenon is far from exceptional and can even be a generic problem when the covariates contain the prior score attainments, a typical situation in value added modeling. Starting from a general, model-free definition of value added, the paper derives an explicit expression of the value added in an endogeneous hierarchical linear Gaussian model. Inference on value added is proposed using an instrumental variable approach. The impact of endogeneity on the value added and the estimated value added is calculated accurately. This is also illustrated on a large data set of individual scores of about 200,000 students in Chile. 相似文献
In this paper we study the influence of residential water access on subjective well-being. The data come from original field work that includes 535 households in Sucre, Bolivia, a city with deficits in the water service. We relate two subjective well-being measures, satisfaction with life and satisfaction with the water domain, to water access variables. It could be the case that the effect of water access variables in subjective well-being could be spurious. That is, water access variables could be capturing shortfalls in other basic needs, such as a lack of income. In order to avoid spurious conclusions, we include socioeconomic variables such as income and place of residence in the regression as control variables. In addition, people might adapt to having poor access to water. The significance of the coefficients of the water variables could lead us to conclude that people do not adapt, but non significance means we cannot reject this possibility. In the econometric regressions, water variables such as water cuts, water quality and access quality, when added to the control variables, increase goodness-to-fit affecting both subjective well-being measures. Our results permit to assess the importance of key elements of access to water in the region under study by relating them to subjective well-being and reveal that water access influences subjective well-being beyond adaptation and other socioeconomic characteristics. Taking this into consideration, we propose that well-being studies in developing countries should consider water access aspects. 相似文献
ABSTRACTSpiritual intelligence has gained increasing importance as an academic construct in the field of psychology. We present the psychometric properties for the Portuguese adaptation of the Spiritual Intelligence Self-Report Inventory-24, SISRI-24. The exploratory analysis showed a factorial structure different from the original scale, comprising three factors instead of four as in the original version, in which “Transcendental Awareness” was removed. The confirmatory factorial analysis revealed adjustment to a three-factor model for the Portuguese version. The main indexes of adjustment are generally better than the original four-factor version, suggesting the adequacy of this solution for the Portuguese population. The analysis with the convergent measures (SWBQ and MPWQ) provides evidence of the construct’s validity and criterion. The results are promising, allowing us to proceed with the uses of this tool for measuring spiritual intelligence, which may, however, be improved in the future. 相似文献
Most work–life research focuses on the spillover of the nuclear family to the workplace, offering little insight into how other family relationships and friendships can spill over to affect employees’ organizational attachment. Past research has also overlooked the role of relationship quality and the mechanisms underlying these life-to-work spillover effects. Addressing these shortcomings, we integrate the systemic model of community attachment with job embeddedness theory to develop a model of community relational embeddedness and then use this model to examine how nonwork relationships connect people to their workplaces.
Design/Methodology/Approach
We used survey data from a national sample of 2025 accounting professionals and tested mediation hypotheses using structural equation modeling.
Findings
Employees’ relationships with friends and family predicted their attachment to their communities, which in turn predicted their workplace turnover intentions. Supporting our theoretical model, bonds with friends and family predicted moving intentions, and community fit and sacrifice mediated these effects. Community fit and sacrifice also predicted work turnover intentions indirectly through moving intentions. Tests also revealed that, surprisingly, friendships had a stronger impact on community attachment than family.
Implications
Employees are connected to their organizations through an array of close community relationships that extend beyond the nuclear family (i.e., spouse, children). Organizations can enhance employees’ workplace attachment by recognizing the role of friends and offering work–life programs that use a broad conceptualization of family (e.g., adult siblings, parents).
Originality/Value
Our study illustrates the importance of community relationships to workplace attachment, and the need to incorporate relational quality, nonnuclear family, and friendships in future research.
We examine the relationship between leader–member exchange (LMX) quality and advice network centrality using multisource data from a sample of 250 retail employees and their respective managers in Turkey to test our hypothesized model of value and costs of being sought out for advice. Drawing upon the tenets of network generation theory (Nebus, 2006 ), we predict that the tendency of focal actors to help others and their own tendency to gossip would be behavioral moderators of the relationship between LMX quality and their advice network centrality. Consistent with network generation theory, our results reveal that LMX quality is positively related to centrality only for those actors with a high tendency to help coworkers and a low tendency to gossip about coworkers, suggesting that behaviors indicating helpfulness and discretion are necessary for high LMX members to maintain a central position in their work group's advice network. Implications and future research directions are discussed. 相似文献
