Wild octopuses at an Australian site frequently propel shells, silt, and algae through the water by releasing these materials from their arms while creating a forceful jet from the siphon held under the arm web. These "throws" occur in several contexts, including interactions with conspecifics, and material thrown in conspecific contexts frequently hits other octopuses. Some throws appear to be targeted on other individuals and play a social role, as suggested by several kinds of evidence. Such throws were significantly more vigorous and more often used silt, rather than shells or algae, and high vigor throws were significantly more often accompanied by uniform or dark body patterns. Some throws were directed differently from beneath the arms and such throws were significantly more likely to hit other octopuses. Throws targeted at other individuals in the same population, as these appear to be, are the least common form of nonhuman throwing.

Abstract. Applicant job pursuit intentions impact the composition of an organization’s applicant pool, thereby influencing selection outcomes. An example is the self-selection of women and men into gender-congruent jobs. Such self-selection contributes to a lack of gender diversity across a variety of occupations. We use person-job fit and the role congruity perspective of social role theory to explore job pursuit intentions. We present research from two cross-sectional survey studies (520 students, 174 working adults) indicating that at different points in their careers women and men choose to pursue gender-congruent jobs. For students, the choice was mediated by value placed on the job’s associated gender-congruent outcomes, but for working adults it was not. We offer suggestions for practitioners and researchers.

Society is a person in its social relations. If the term "society" is used to determine reality as a system of interconnections and relationships between people, then its social system appears as an entity in which human societies are diverse in character and social role. Social life is expressed in the grouping of members of society on the basis of certain objectively predetermined types of relations between them. The integrity and unity of religious communities, their qualitative specificity determines the content of the doctrine and cult, on which they grow.

The extensive commercial success of two well-made popular television drama serials screened in the UK at prime time on Sunday evenings during the winter of 2011–12, Downton Abbey (ITV, 2010–) and Call the Midwife (BBC, 2012–), has appeared to consolidate the recent resurgence of the period drama during the 1990s and 2000s, as well as reassembling something like a mass audience for woman-centred realist narratives at a time when the fracturing and disassembling of such audiences seemed axiomatic. While ostensibly different in content, style and focus, the two programmes share a number of distinctive features, including a range of mature female characters who are sufficiently well drawn and socially diverse as to offer a profoundly pleasurable experience for the female viewer seeking representations of aging femininity that go beyond the sexualised body of the ‘successful ager’. Equally importantly, these two programmes present compelling examples of the ‘conjunctural text’, which appears at a moment of intense political polarisation, marking struggles over consent to a contemporary political position by re-presenting the past. Because both programmes foreground older women as crucial figures in their respective communities, but offer very different versions of the social role and ideological positioning that this entails, the underlying politics of such nostalgia becomes apparent. A critical analysis of these two versions of Britain's past thus highlights the ideological investments involved in period drama and the extent to which this ‘cosy’ genre may legitimate or challenge contemporary political claims.

Using data from the National Longitudinal Survey of Youth-Mother and Child samples, I investigated the relationships among child and adolescent depressive symptoms, having a chronically ill sibling, and other child and familial demographic variables. From research on social support and social role transitions, with the Stress Process as a theoretical model, I hypothesized that children with chronically ill siblings experience more depressive symptoms. Specifically, I looked at age, gender, birth order and family size as potentially reducing the effect size of having a chronically ill sibling. Findings showed that having a chronically ill sibling is associated with demonstrating more depressive symptoms both in the bivariate and multivariate analyses. Although age, gender, birth order and family size do not interact significantly with having a chronically ill sibling in predicting depressive symptoms, they do present interesting findings about childhood depressive symptoms in general. Thus, the results of this study suggest specific and meaningful paths for future research.

Abstract Entrepreneurial spirit plays an increasingly important role in the economic sphere, and universities are meant to play a central role in this process, where the main objective is the continuous development and mediation of the knowledge increasingly geared to the applications through innovation and patenting a secure platform for employment and well-being growth. The Universities have to take a position in if/and how they want to grow into a so-called “University of Entrepreneurship” which is characterized by a high degree of openness to the surrounding society and here we are talking, especially, about, the business sector in Romania. This evolution of expectations for the social role of universities has resulted from increased and recent interest in entrepreneurship and innovation of areas as research and theory of the business environment. The experience gained as teachers indicates that education and entrepreneurship education should include different theories and methodology than those applied in the usual way. The theory of traditional management and microeconomic models could even be a barrier to new thinking and change and, therefore, to the implementation of modern entrepreneurial actions. We want this article to be a source of inspiration for educational institutions and to have a positive contribution to research in business education and to be applicable in business decision-making.

The article assesses synergetic theory of document as a new development in document science. In information society the social role of document grows, as information involves all members of society in the process of documentation. The transformation of document under the influence of modern information technologies increases its interest to representatives of different sciences. Interdisciplinary nature of document as an object of research leads to an ambiguous interpretation of its nature and social role. The article expresses and contends the author's views on this issue. In her opinion, social role of document is incidental to its being a main social tool regulating the life of civilized society. Thus, the study aims to create a scientific theory of document, explaining its nature and social role as a tool of social (goal-oriented) action and social self-organization. Substantiation of this idea is based on application of synergetics (i.e., universal theory of self-organization) to scientific study of document. In the synergetic paradigm, social and historical development is seen as the change of phases of chaos and order, and document is considered a main tool that regulates social relations. Unlike other theories of document, synergetic theory studies document not as a carrier and means of information transfer, but as a unique social phenomenon and universal social tool. For the first time, the study of document steps out of traditional frameworks of office, archive, and library. The document is placed on the scales with society as a global social system with its functional subsystems of politics, economy, culture, and personality. For the first time, the methods of social sciences and modern sociological theories are applied to scientific study of document. This methodology provided a basis for theoretical vindication of nature and social role of document as a tool of social (goal-oriented) action and social self-organization. The study frames a synergetic theory of document with methodological foundations and basic concepts, synergetic model of document, laws of development and effectiveness of document in the social continuum. At the present stage of development of science, it can be considered the highest form of theoretical knowledge of document and its scientific explanatory theory.
