This paper focuses on biotechnologies and biotech companies. Our aim is to develop a model for assessing the openness degree of knowledge governance strategies, applying it to the biotech firms. Biotech production is described as an emerging meta-industry in the global economy, fostering through new products, many socio-economic fields. Its main features are: a close relationship among knowledge, innovation and competitiveness; the need for collaborative research; the importance of small firms. Our paper begins with a brief characterization of the biotech meta-sector. We then review the literature regarding the advantages and disadvantages of ??wholly proprietary?? versus ??wholly open?? knowledge strategies. Next we propose a model and report the main results of its application to biotech companies in Italy. In conclusion, we evaluate the degree of openness of the company knowledge strategies based upon empirical evidence from our research in the field.  相似文献

Research in social psychology has shown individual variation in the tendency to compare one’s own opinions and abilities with those of other people, raising the question of whether social comparisons are psychological dispositions. To test the empirical validity of this proposition, Gibbons and Buunk (1999) created an instrument, the Iowa–Netherlands Comparison Orientation Measure (INCOM), that measures the tendency to engage in social comparison and captures central aspects of the self and the other. This paper analyzes the reliability and validity of the INCOM scale for the German population and discusses potentials for shortening the instrument for continued use in large-scale population surveys. Interdependencies between psychological and structural characteristics are investigated and consequences for life satisfaction discussed. The results show evidence that individuals systematically vary in their orientation towards social comparison.  相似文献

ABSTRACT

Objective: Disordered eating behaviors among undergraduate women are common and, thus, are an important public health concern. Weight stigmatization, stress, and social withdrawal are often associated with disordered eating behaviors; however, it is unclear whether stress and social withdrawal act as mediators between weight stigmatization and disordered eating. By testing specific pathways to disordered eating, theory-driven prevention programs can be implemented. Methods: Self-reported surveys were administered to 217 undergraduate women during the Fall 2014 semester. Results: There were 2 distinct mediational pathways in response to weight stigmatization. Stress partially mediated the path between weight stigmatization and emotional eating (38%), whereas social withdrawal partially mediated the path between weight stigmatization and dietary restraint (44%). Conclusions: Stress and social withdrawal mediate the relationship between weight stigmatization and disordered eating. The results of this study identified potentially critical risk factors that, if addressed, may improve outcomes of campus-based disordered eating programs for women.  相似文献

Although Italy and Portugal are considered to be part of the same welfare state family – the Southern European one – analysis of a key component of the welfare state, namely, unemployment policies and regulations, reveals a different evaluation. A comparative analysis of a series of specific indicators of Italian and Portuguese unemployment regimes shows that they represent two different models. Portugal appears to be a more inclusive system, closer to continental or Northern European countries than it is to Italy, or at least representing a hybrid system that combines characteristics of continental European welfare states with characteristics that are more typical of Southern European welfare states. Italy, on the contrary, is much more clearly a Southern European welfare state.  相似文献

BackgroundMany post-partum women hold risky beliefs about perceived therapeutic benefits of sun-exposure in the post-partum period and infancy.QuestionCan a maternity hospital based educational intervention reduce the prevalence of such beliefs among post-partum women?MethodsIn this outcome evaluation of an interventional study, two groups of healthy post-partum women (hospital inpatients) were interviewed, 1–4 days following delivery. The first cross-section (106 women) was recruited prior to in-services for maternity staff; the second (203 women) was recruited after completion of the in-services. Data were compared between the groups.FindingsMore pre-intervention than post-intervention women reported they would expose their baby to sunlight to treat suspected jaundice (28.8% vs 13.3%; p < 0.001) or help his/her skin adapt to the sun (10.5% vs 2.5%; p = 0.003); or use sunlight to manage breastfeeding-associated sore/cracked nipples (7.6% vs 2%; p = 0.026).ConclusionThis simple, effective educational intervention could be implemented in programmes for parents, health professionals and students.  相似文献

During their follow-up, patients with cancer can experience several types of recurrent events and can also die. Over the last decades, several joint models have been proposed to deal with recurrent events with dependent terminal event. Most of them require the proportional hazard assumption. In the case of long follow-up, this assumption could be violated. We propose a joint frailty model for two types of recurrent events and a dependent terminal event to account for potential dependencies between events with potentially time-varying coefficients. For that, regression splines are used to model the time-varying coefficients. Baseline hazard functions (BHF) are estimated with piecewise constant functions or with cubic M-Splines functions. The maximum likelihood estimation method provides parameter estimates. Likelihood ratio tests are performed to test the time dependency and the statistical association of the covariates. This model was driven by breast cancer data where the maximum follow-up was close to 20 years.  相似文献

Recent years have seen increased attention paid to monitoring social anomie and its dependency on micro- and macro-factors. In this paper, we endorse the theorisation of social anomie as a complex, multidimensional and multilevel phenomenon. To ensure a rigorous measurement of the varying levels of social anomie in the European countries, the current study relies on a multilevel multidimensional item response theory model which explicitly accounts for the presence of a non-ignorable missing data mechanism. This unified approach makes it possible to specify an analytical model of links between anomie features and their determinants and to explore how the latent traits of interest are influenced by individual-level factors, as well as by country-level indicators. Additionally, to avoid misleading inferential conclusions, the proposed model takes into account the respondent’s omitting behaviour, assuming that the missingness mechanism is driven by a latent propensity to respond. Data used in this study have been collected in the 2010 wave of the European Social Survey. To reduce the computational complexities, a Bayesian specification of the MIRT model is provided and the parameter model estimates are obtained through MCMC algorithms.  相似文献

This article analyzes infanticide based on the Coroners' Records for Providence County, Rhode Island, from the 1870s to 1938 to determine doctors' and coroners' attitudes toward mothers who killed. The nineteenth century witnessed a medical discourse on the possibility of postpartum insanity as a cause of infanticide. While some women claimed temporary insanity, and some doctors and coroners legitimated this defense, its application to mothers who killed was arbitrary. They determined who deserved this diagnosis based on the woman's character, her forthrightness, and extenuating circumstances. Infanticide divided the profession nationally and at the local level and prevented doctors or coroners from speaking in a united voice on the issue. This article does not attempt to follow cases of infanticide through to jury verdicts. Instead, it provides an opportunity to analyze the circumstances women faced that led them to kill their newborns, and to analyze the responses of doctors and coroners to these mothers who killed. Unlike the findings of other studies, neither physicians nor coroners in Rhode Island were united in a claim of ignorance to save these women from guilty verdicts.  相似文献

While it is generally agreed that income inequality affects an individual’s well-being, researchers disagree on whether people living in areas of high income disparity report more or less happiness than those in more equal environments, thereby indicating the need to study how and why income inequality matters to the individual’s well-being. Findings on group-specific reaction patterns to income inequality further fuel this need. Alesina et al. (2004) argue that a preference for inequality and the perception of the possibility of social mobility account for the indistinct relationship between income inequality and subjective well-being. Combining this hypothesis with previous research on social cognition and drawing on social justice theory, this paper aims to demonstrate the mediating nature of perceptions of income inequality. It argues that the perceived legitimacy of distributive outcomes and procedures contributes to how income inequalities affect individuals and their sense of well-being. The empirical analysis is based on data from the International Social Justice Project, developed from face-to-face interviews with a representative sample of the German population. Using structural equation modeling, the paper finds structural biases in the perception of income inequality. The paper concludes that subjective well-being is a product of the individual’s perception and legitimating processes. The results indicate that social cognition is a useful tool for studies of income inequality and subjective well-being.  相似文献
