ABSTRACTHow do we study social media technology? While social semiotics provides an extensive toolkit for analysing multimodal texts and semiotic practices, the study of social media as semiotic technology poses a significant challenge to existing research methodologies. In this article, we present a social semiotic framework that allows us to describe in analytical details the multimodal meaning potentials offered by digital social media technology and connect these to multimodal text-making and semiotic practices while underscoring the role of technology. Our framework is organized around seven interrelated and inherently informed dimensions: (1) multimodality, (2) practice, (3) the social, (4) medium, (5) the material, (6) the historical, and (7) the critical. This framework could pertain to most types of semiotic technologies, but will here be developed for accounting for social media technologies, and its viability will be illustrated with examples from Instagram. By developing this framework, we aim at elaborating the theoretical basis and analytical tools of social semiotics, and thereby contributing to bringing forward increased understanding of how social media technology enables making, enacting and managing meaning. 相似文献

Stature estimation methods for Danish adult population have generally relied on Trotter and Gleser’s and Boldsen’s regression equations that are based on the skeletal remains of recent war dead American Whites, Terry Skeletal Collection, and Danish archaeological medieval skeletal materials, respectively. These equations are probably not suitable for stature estimation in contemporary Danish forensic cases. Furthermore, because postmortem computed tomography (PMCT) is now routinely performed at Danish forensic departments, equations based on PMCT, rather than measurements of defleshed bones, are needed. The aim of this study was to develop new equations for adult stature estimation based on PMCT femoral measurement. Maximum femoral length was measured on the PMCT images of 78 individuals (41 males and 37 females) aged 23–45 years. The measurement accuracy was tested on dry bones, and all the measurements were included in the inter- and intra-observer analyses. Both analyses results demonstrated the reliability of the method and data. Comparison between the living stature of the individuals and the estimates based on the equations by Trotter and Gleser and Boldsen demonstrated the unreliability of the previous equations to some extent. New regression equations were then developed and validated on a different sample of 18 Danish forensic cases. Comparisons of all the equations indicated that both the sets of previous equations underestimated the stature in the new validation dataset. The new equations developed in this study provide a reliable alternative for stature estimation in modern Danish forensic cases. 相似文献

Studies have shown how women are underrepresented in senior executive positions in public and private organizations. Equal representation matters both for reasons of performance and legitimacy, and, to understand the mechanisms behind the glass ceiling, we explore if the women making it to the top of the Danish civil service differ from the men who do so. We want to understand if senior executive positions require something different of women than men. Using a dataset consisting of the entire career trajectory of all senior civil servants in Denmark, we find that, on numerous human capital dimensions, the women and men making it to the top are quite similar, for example, in terms of tenure and educational level. However, we find on the one hand that men are more often employed in the most prestigious departments and, at the same time, it seems that men with a profile deviating from the norm are more likely to make it to the top than women. This may indicate that the most prestigious positions – also in terms of early-career positions – are less accessible to women, and that women are less willing to apply for jobs outside their usual domain, or that those responsible for recruitment are less willing to take a chance on a woman with a slightly unorthodox profile. Hence, our study indicates that greater interest should be paid to the dynamics keeping women at lower levels of the hierarchy and possibly to encourage them to apply for top positions. 相似文献

This article analyzes the most recent phase of Japan’s security policy reform, focusing on its shifting priorities towards the Japan Self-Defense Forces and the Japan–US alliance since mid-2010. From a realist perspective, it argues that these shifting military priorities first and foremost represent a traditional counterbalancing response to China’s rise. Conforming to the logic inherent in balance of threat theory, it moreover argues that this balancing behavior is explained by a confluence of two primary factors, namely Japanese perceptions of aggressive Chinese behavior in the maritime domain and concerns relating to the changing distribution of capabilities in China’s favor. 相似文献

In this article we present the results of our studies of gender construction at work in Icelandic fish plants. Our aim is to contribute to the understanding of the processes involved in the gendering of jobs, labour and the organization of work and their interrelations. We argue that an examination of these factors can shed light on larger questions of gender segregation, women's lower position in the labour force and how gender categories and identities are constructed and reconstructed in the workplace. 相似文献

Prostitution is a worldwide phenomenon, and so are the controversies surrounding it. In Denmark, as in many countries, there is an ongoing public debate about whether it should be seen as a social/political problem, or as a job like any other. The debate takes place within the tension between welfare state discourses and neo-liberal discourses. 相似文献

Politicians bias public policies to favor particular election districts. According to the traditional common pool model, districts facing low tax shares should receive relatively large government projects. We suggest a swing-voter model where the number of voters on the ideological cut point, lack of party identification and number of district representatives per voter determine project sizes. We analyze the allocation of state road investments in Norway from 1973–1997 exploiting unique data on characteristics of voters, legislative representation and tax prices in 19 election districts. Geographical representation to parliament is biased, mostly due to an ancient constitution. Shares of swing voters and legislative over-representation lead to higher levels of road investments, while high levels of party identification reduce investments. 相似文献

Adrenocorticotropic hormone (ACTH) is involved in systemic reactions to stress. The aim of the present study was a comprehensive analysis of serum and cerebrospinal fluid (CSF) levels of ACTH, and the pituitary immunohistochemistry with special regard to fatal hypothermia in routine forensic autopsy cases (n=162: 5-97 years of age; 114 males and 48 females; 4 h to 3 days postmortem, median, 19.2 h). The ACTH concentrations were independent of the postmortem time, gender, or age of the subjects. The serum ACTH level was similar to the clinical reference value for sharp instrument injury, fire fatality, and hypothermia, but was lower in other groups including hyperthermia, in particular for asphyxia and poisoning. The CSF level was usually much higher than the serum level, but was significantly lower for hypothermia and hyperthermia than in other groups (p<0.01). The rate of ACTH-immunopositivity in the anterior pituitary was low in cases of fatal hypothermia and hyperthermia, while it was high in cases of blunt injury, fire fatality, and acute ischemic heart disease. These observations showed that ACTH levels in the serum and CSF depended on the cause of death. The serum level was maintained despite a low CSF level and pituitary immunopositivity for fatal hypothermia, while the serum and CSF levels as well as pituitary immunopositivity were decreased for hyperthermia. 相似文献

The public sector frequently confronts a heightened societal turbulence triggered by an increasing number of unpredictable and disruptive economic, political, and environmental crises. How can the public sector respond to this challenge? This article argues, first, that to continue to provide relevant solutions, public governance must be robust in the sense of adapting and innovating policies, programs, and services in ways that facilitate the achievement of basic public ambitions, functions, and values in the face of challenges, stressors, and threats. Second, to build robust governance, public managers must engage in bricolage and become bricoleurs in order to flexibly combine elements from competing and co-existent public governance paradigms. Doing so necessitates the construction of institutions conducive to bricolage, that is, institutions that are characterized by a high degree of flexibility that allows for experimentation; institutions that foster inclusive deliberation, knowledge sharing and joint learning; and institutions that balance centralization with distributed agency. 相似文献
