ABSTRACT

On 8 July 2013, Sports Illustrated media critic Richard Deitsch – inspired by a photo that captured a friend celebrating with a brother who had won the NCAA Hockey Championships – asked his 90,000-plus Twitter followers if they had the best moment of their life captured in a photograph. Deitsch retweeted the initial pictures, which prompted many more people to send out photos of their favorite moments. Many of his followers shared photos of some of their most intimate moments, leading CNN to call Deitsch ‘the sportswriter who made Twitter cry’ [Mendoza, D. (2013, July 11). The sportswriter who made Twitter cry. CNN. Retrieved December 11, 2013, from http://www.cnn.com/2013/07/11/tech/storify-best-moments/.s]. Through a thematic examination of 314 photos shared in the Deitsch exchange, the authors reveal that an overwhelming number of images are identified as milestone moments, or narratives of life experience, which denotes that as communication platforms evolve and technologies offer different modes of expression, users are still selecting narrative structure to disseminate their messages.  相似文献

This paper examines some of the assumptions and consequences of the use of distance as a measure of structural equivalence, as implemented in Burt's STRUCTURE program. We take the general perspective that for a measure to be useful it should not confound separate types of information which are theoretically and mathematically independent. The mathematical relationship between distance and the Pearson product moment correlation coefficient is presented. We show that use of distance as a measure of similarity without proper attention to appropriate standardization procedures confounds information on differences between means and differences between variances with information on the similarity of the patterns between pairs of individuals, e.g. correlation. A detailed examination of Burt and Bittner's analysis of Bernard, Killworth and Sailer's Ham radio operator group is presented, and it is demonstrated that use of distance as a measure of structural equivalence led to nonsensical results.  相似文献

The paper explores the feasibility of using interactive graphic based solution procedures in location problems with discrete choices. It compares solutions generated through interactive graphics with those generated through optimization for a problem context where service centres had to be located in rural India. The comparison demonstrates the feasibility of generating near optimal solutions for problems with a certain dimensionality. Broad features of the graphic software are described. The paper also highlights other advantages and limitations of the interactive graphic procedure.  相似文献

In a series of papers on informant accuracy in social network data, Bernard, Killworth, and more recently, Sailer, have concluded that “what people say, despite their presumed good intentions, bears no useful resemblance to their behavior” (Bernard, Killworth, and Sailer 1982: 63). In this paper we reanalyze one of the data sets (the technical group) utilized by Bernard, Killworth and Sailer in arriving at their conclusions. Unlike Bernard et al. we find that the observed behavior data corresponds closely to the recalled data. Using different methods of analysis we find that the verbal recall data can be used to predict structural aspects of the observed data. Two major findings emerge from our analysis: first, the more similarly two people judge the communication pattern of others, the more they interact with each other, and, second, the more two people share accurate knowledge of others, the more they interact with each other. Implications of our findings for the assertions of Bernard, Killworth and Sailer are discussed.  相似文献

This paper attempts to develop a multiobjective model to help policy-makers choose the most appropriate mix of economic policies concurrent with the elimination of serious gaps. Each individual policy attempts to achieve a specific goal or a set of subgoals; but it may hinder the achievement of some other subgoals. To differentiate between the importance of different objectives, the analyst assigns different priorities to each of the given set of subgoals. Three sets of results are provided by three separate computer runs of this model. Each set of results corresponds to one of the three priority structures, and each run indicates quite differing underachievements or over-achievements of individual subgoals. A detailed explanation for each of these deviations (gaps) from the targeted subgoals is attempted in an overall framework and some interactions between various gaps (savings gaps, foreign exchange gap, domestic growth gap, GNP gap, etc.) are also identified.  相似文献

The influence of disabilities on placement outcomes was examined for 277 children who were removed from their biological parents due to substantiated maltreatment. Results indicated that children with a disability were less likely to reunify and more likely to reside in nonkin foster care two years later than typical children. Children with cognitive, emotional /behavioral, and physical disabilities were over four times more likely to be permanently living in nonkin foster care than to be reunified.  相似文献

The main points made in the previous papers are summarized and integrated and the strategies that the authors have recommended for producing an improved QOL are discussed. QOL is also systematically reviewed in relation to matters of definition, assessment, applications, and directions for future research and practice.  相似文献

This paper presents a method for normalizing grouped data that exhibits response or sample bias as reflected by unequal marginal totals. The use of the method is illustrated on triad data of judged similarity of meaning collected in Guatemala. The model should have wide utility in the social sciences.  相似文献

We have established a comprehensive diagnostic paradigm for the management of aging men which seeks to evaluate the various determinants of the aging process in five major health areas: cardio-health, bone health, sex health, general health and endocrine state. This paradigm appears to be useful for the management of the problem of aging in our local population. It could be used for the management of individuals as well as for population research. When combined with the establishment of evidence-based management modalities, it will provide a useful tool for the holistic management of aging in Asia.  相似文献
