There is a paucity of empirical studies of public relations in Italy. This study sought to assess whether public relations departments are managed strategically in Italy and whether public relations contributes to the strategic management of organizations. Using the four generic principles that deal with strategic management, this study gathered data from public relations professionals working in the three major types of organizations: corporations, government agencies, and non-profits. The study found that regardless of the type of organization, few public relations practitioners are represented in the senior management of their organizations. Senior managers of non-profits tended to value public relations more than the other two sectors. Symmetrical communication again proved to be normative. By using a conceptual framework and research instruments that have been employed in studies conducted in other parts of the world, this study has generated data that can be used to compare strategic public relations in different socio-cultural environments – thus contributing to building a global theory of public relations.  相似文献

The development of the ability to recognize the whole human body shape has long been investigated in infants, while less is known about their ability to recognize the shape of single body parts, and in particular their biomechanical constraints. This study aimed to explore whether 9‐ and 12‐month‐old infants have knowledge of a hand‐grasping movement (i.e., pincer grip), being able to recognize violations of the hand's anatomical constraints during the observation of that movement. Using a preferential looking paradigm, we showed that 12‐month‐olds discriminate between biomechanically possible and impossible pincer grips, preferring the former over the latter (Experiment 1). This capacity begins to emerge by 9 months of age, modulated by infants' own sensorimotor experience with pincer grip (Experiment 2). Our findings indicate that the ability to visually discriminate between pincer grasps differing in their biomechanical properties develops between 9 and 12 months of age, and that experience with self‐produced hand movements might help infants in building a representation of the hand that encompasses knowledge of the physical constraints of this body part.  相似文献

We use the last two waves of the Italian Time Use Survey to analyse whether children imitate the reading habits of their parents. As reading is crucial for continuous investment in human capital throughout a person’s life, it is important that children acquire the habit of reading. This habit may be developed through both cultural and educational transfers from parents to children, and through imitative behaviours. Imitation is of particular interest, as it suggests that parents can have a direct influence on the formation of their children’s preferences and habits, and that active policies promoting good parenting behaviours might therefore be desirable. We investigate the short-run imitative behaviour of children using a household fixed-effects model in which we identify the impact of the parents’ role model by exploiting the differences in the exposure of siblings to their parents’ example within the same household. We find robust evidence of the existence of an imitation effect: on the day of the survey, children were more likely to had read after seeing either their mother or their father reading.  相似文献

Augmented reality is a new technology that merges the virtual and the real worlds and offers important support in all planning processes. Using mobile devices, planning information can be implemented with smart and participative solutions for a dynamic fruition of cultural heritage [Brondi, R., Carrozzino, M., Tecchia, F., & Bergamasco, M. (2012) Mobile augmented reality for cultural dissemination, in: P. Nesi & R. Santucci (Eds), ECLAP 2012 Conference on Information Technologies for Performing Arts, Media and Entertainment, pp. 113–118 (Firenze: Firenze University Press); Hatzelhoffer, L., et al. (2012) Smart City in Practice: Innovation Lab Between Vision and Reality (Jovis). Technologies are important tools because they make a city smart by making concrete contributions to trigger dynamic processes of place-based development. Three important factors improve urban planning fruition: participation in the early stages of listening and co-design; enlightened governance and new technology. This paper (1) presents the actual possibilities and challenges of augmented reality in the field of cultural heritage, (2) describes a simulation of one case study in a neighbourhood in Cagliari (Italy), by proposing customized paths with the aim of promoting cultural tourism and (3) explains the benefits of using augmented reality in touristic and place-based processes based on the case study.  相似文献

Affymetrix's SNP (single-nucleotide polymorphism) genotyping chips have increased the scope and decreased the cost of gene-mapping studies. Because each SNP is queried by multiple DNA probes, the chips present interesting challenges in genotype calling. Traditional clustering methods distinguish the three genotypes of an SNP fairly well given a large enough sample of unrelated individuals or a training sample of known genotypes. This article describes our attempt to improve genotype calling by constructing Gaussian mixture models with empirically derived priors. The priors stabilize parameter estimation and borrow information collectively gathered on tens of thousands of SNPs. When data from related family members are available, our models capture the correlations in signals between relatives. With these advantages in mind, we apply the models to Affymetrix probe intensity data on 10,000 SNPs gathered on 63 genotyped individuals spread over eight pedigrees. We integrate the genotype-calling model with pedigree analysis and examine a sequence of symmetry hypotheses involving the correlated probe signals. The symmetry hypotheses raise novel mathematical issues of parameterization. Using the Bayesian information criterion, we select the best combination of symmetry assumptions. Compared to Affymetrix's software, our model leads to a reduction in no-calls with little sacrifice in overall calling accuracy.  相似文献

This article reviews standard sources of demographic data‐censuses, intercensal surveys, registration systems, and specialized surveys and describes their inability to provide accurate data on immigrants, particularly those without documents. We discern a need for data that can identify undocumented migrants and their characteristics, measure trends over time, support longitudinal research, compare the characteristics of migrants before and after they enter, provide sufficient sample sizes for detailed analyses, study transitions between different legal statuses and movements back and forth, and monitor the effects of policy changes on a timely basis. We suggest that the ethnosurvey design satisfies these criteria. We describe the theory, structure, and organization of the ethnosurvey and then describe its application in the Mexican Migration Project. We then highlight its application in other locations around the world and outline an agenda for future comparative research.  相似文献

There is a substantial mainstream literature on coming out in organizations, which investigates the positive effects for gay people of being out at work, but very few contributions that challenge the discourse of coming out. Taking as its starting point Butler's famous question ‘So we are out of the closet but into what?’, this paper problematizes coming out discourses in the workplace. We report on a study in which ten men were invited to talk about their coming out in the workplace. There were three main ways through which our participants constituted themselves as gay men when they talked about coming out: by defining themselves as, and admitting to, being gay; by introducing themselves as being in a gay relationship; and by adopting legitimate subject positions such as the Other, the different one, or the normal gay. Through our analysis, discussions and conclusions, we show how participants position themselves within different discursive variations, thus revealing the multiplicity of ‘the gay self’ and highlighting how coming out repeats and supports normative systems.  相似文献

Autonomy is known for its positive effects and its use in management practice. Recently an urgent debate has emerged on its drawbacks on individual outcomes. In this study, we investigate and test a model on the effect on individual learning of an autonomy‐supportive teaching style and its interplay with the learner's previous experience and perceived management support. Specifically, while research has emphasized the positive effect of similar contexts, this study focuses on its differential effect on short‐term and long‐term learning outcomes, challenging the traditional view of autonomy. We also explore how job experience and management support can improve the effects of autonomy on individual learning. We test our model by collecting longitudinal data on a sample of 200 individuals participating in a training programme on managerial skills. Our results show that (1) the extent to which teachers were perceived as autonomy‐supportive presents a linear relationship with short‐term learning outcomes (utility reactions) and a positive curvilinear relationship with training transfer in the long term; (2) learner job experience and perceived management support for learning have a positive moderating effect on the linear relationship between autonomy and learning outcomes.  相似文献

This article analyses the main shifts in the political and public discourse about families, children, elderly people, care needs and women‐friendly policies in Italy over the last two decades. It shows that while family and gender relationships have become an ideologically highly charged public issue, policies at the practical level have remained largely stagnant, marginal and fragmentary. At the same time, important institutional changes (such as the constitutional reform of 2001, which introduced a form of federalism) have created new problems of governance. The authors argue that in the face of inadequate policies, the recourse of individuals and families to old (family solidarity) and new (migrant labour) solutions may cause new tensions and inequalities.  相似文献
