'Flesh and blood' : notions of relatedness among some urban English women

Savage, Jan Cecelia January 1991 (has links)
This study, concerned with perceptions of relatedness, is partly based on tape-recorded, semi-structured discussions with ninety-seven English women. Except in the case of my principal informant, these discussions took place in a London family planning clinic over two six-month fieldwork periods during 1985 and 1987. Discussions with my principal informant, who was recruited through an ante-natal clinic, took place over a four and a half year period. The study also analyses eighty drawings of the body made by sixteen of the informants. The study suggests that the expressions 'blood' and 'flesh and blood' which are used by informants to describe 'kinship' relationships denote the recognition of a common identity, but do not consistently refer to a biological relationship. Instead, these expressions appear to indicate a complex model of procreation which incorporates both social and biomedical knowledge. This model appears to inform a view of relatedness which includes understandings of biomedical genetics and certain notions of 'openness', 'closeness' and 'sameness' which can be interpreted in either physical or metaphysical terms. These notions have implications for the way in which the body and individuality are perceived. It is suggested, for example, that in certain circumstances, the 'person' and the 'body' are not isometric for those of the same 'flesh and blood'. The study is thus particularly concerned with the cultural construction of the body and the way in which the relationships between such constructed bodies are understood. It aims to contribute towards an understanding of the little-examined ontological basis of western 'kinship', particularly in the context of new reproductive technologies which stress genetic relatedness.

Graph-Based Keyphrase Extraction Using Wikipedia

Dandala, Bharath 12 1900 (has links)
Keyphrases describe a document in a coherent and simple way, giving the prospective reader a way to quickly determine whether the document satisfies their information needs. The pervasion of huge amount of information on Web, with only a small amount of documents have keyphrases extracted, there is a definite need to discover automatic keyphrase extraction systems. Typically, a document written by human develops around one or more general concepts or sub-concepts. These concepts or sub-concepts should be structured and semantically related with each other, so that they can form the meaningful representation of a document. Considering the fact, the phrases or concepts in a document are related to each other, a new approach for keyphrase extraction is introduced that exploits the semantic relations in the document. For measuring the semantic relations between concepts or sub-concepts in the document, I present a comprehensive study aimed at using collaboratively constructed semantic resources like Wikipedia and its link structure. In particular, I introduce a graph-based keyphrase extraction system that exploits the semantic relations in the document and features such as term frequency. I evaluated the proposed system using novel measures and the results obtained compare favorably with previously published results on established benchmarks.

Dual Autonomy: A Culturally Encompassing Reinterpretation of Traditional Autonomy in Clinical Supervision

January 2020 (has links)
abstract: Traditional autonomy within clinical supervision was reinterpreted by incorporating culturally-encompassing autonomy types (individuating and relating autonomy) from the dual autonomy scale. The relations of vertical collectivism and autonomy measures were examined. Lastly, potential moderating effects of vertical collectivism on experience level and autonomy were assessed. The sample consisted of 404 counseling trainees enrolled in graduate programs across the US, aged between 21 and 68. Results from the confirmatory factor analysis supported the proposed two-factor structure of individuating and relating autonomy among counseling trainees for the adapted dual autonomy scale. Results indicated that individuating autonomy was moderately correlated with relating and traditional autonomy, and relating autonomy was not correlated with traditional autonomy. Vertical collectivism was not correlated with relating autonomy, but significantly predicted individuating and traditional autonomy. Moderating effects of vertical collectivism on experience level and autonomy were not supported. Further implications and future directions are discussed. / Dissertation/Thesis / Doctoral Dissertation Counseling Psychology 2020

The Relationship Between Family Recreation and Relatedness in Children and Their Families

Berrett, Kristen 06 December 2010 (has links)
The purpose of this study was to provide insight into the factors contributing to relatedness in children, specifically family recreation, and to look at relatedness between family members (family relatedness), and whether or not family recreation makes a contribution to this construct. Two instruments were used to collect data for this study. The Family Leisure Activity Profile (FLAP) measured family recreation involvement and satisfaction, and the Activity-Feelings States Scales (AFS) measured child and family relatedness. The sample included elementary school children between the ages of 6 years and 12 years (n1=405), and the parents of those children (n2=405). The data showed satisfaction with family recreation activities was a significant predictor of children's relatedness with their peers. The data also showed involvement in balance family recreation activities was a significant predictor of a family's relatedness with one another.

Interpersonal needs and values authenticity, belonging, independence and narcissism

Aiken, Emma, n/a January 2006 (has links)
The nature of human well-being has been debated in psychological research since the beginning of the study of human behaviour. Mechanistic perspectives regard humans to be independent objects motivated by external contingencies, with needs to be both self sufficient and self-enhancing. Organismic perspectives describe humans as having innate self-organisational tendencies, which partly depend on qualities of relationships with others. Basic needs for well-being include being self-determined and socially integrated. Both perspectives claim empirical support. Drawing on Self-Determination Theory (SDT), the present study proposed that basic needs for well-being include autonomy and relatedness, and ego-defensive needs that undermine health include independence, control and narcissism. To compare the effects of different needs on well-being, the present study measured people's perceived needs and the satisfaction of those needs, within the context of interpersonal interactions. Participants were sourced from the student population at a Melbourne university (N = 82), and various internet website forums (N= 171). Included were 82 participants who had received a diagnosis of social anxiety in the past two years. A new measure, the Interpersonal Needs Scale (INS) was developed to tap the strength of values for the five needs of interest, and the degree to which needs are satisfied. Factor analysis on the INS produced four value subscales: these were named Authenticity and Belonging, comprising autonomy and relatedness items, and Independence and Narcissism, both including Control items. The fmal version of the INS showed satisfactory reliability and validity. Results for Study 1 indicated that for the present sample, Authenticity and Belonging values were associated with overall interpersonal need satisfaction and with well-being. Conversely, Independence and Narcissistic values were associated with dissatisfaction of interpersonal needs and compromised well-being. For Study 2, cluster analysis was used to group participants according to their INS profiles: that is, similarities in their perceived needs and their degree of satisfaction of needs. In line with predictions, the groups included: the Selfother Balanced (N = 42), who reported significantly greater values for authenticity and belonging over independence and narcissism, and overall need satisfaction; the Slightly Lonely (N = 53), who reported similar value ranking but some dissatisfaction of needs; the Satisfied Narcissists (N = 45), who reported high values for ego-defensive needs and satisfaction of narcissistic needs only; the Needy Narcissists (N= 81), who also reported high values for ego-defensive needs but high overall need dissatisfaction; and the Individualists (N = 27), who reported low values for belonging and unsatisfied independence needs. The characteristics of each group were analysed and compared with each other according to a range of self-concept measures (autonomous-self, relational self, independent-self, and narcissistic personality), indicators of psychological wellbeing (depression, anxiety, stress, and self-esteem), and social well-being (alienation). The Self-other Balanced group reported the highest well-being scores and a predominantly autonomous self-concept, while those who reported low values for belonging needs (Individualists), and those who reported the least satisfaction of interpersonal needs (Needy Narcissists), reported the most compromised well-being. A large proportion of respondents with social anxiety belonged to the latter group. The implications of these results for understanding the impact of values and the satisfaction of interpersonal needs on well-being were discussed.

Examining Curvilinearity and Moderation in the Relationship between the Degree of Relatedness of Individual Diversification Actions and Firm Performance

Cernas Ortiz, Daniel Arturo 05 1900 (has links)
Corporate diversification continues to be an important phenomenon in the modern business world. More than thirty years of research on diversification suggests that the degree of relatedness among a firm's business units is a factor that can affect firm performance, but the true effect of diversification relatedness on firm performance is still inconclusive. The purpose of this dissertation is to shed more light on this inconclusive association. However, attention is focused on the performance implications of individual diversification actions (e.g., acquisitions and joint ventures) rather than on the overall performance of firms with different levels of diversification. A non-experimental, longitudinal analysis of secondary data was conducted on over 450 unique acquisitions and on more than 210 joint ventures. Results suggest that even when individual diversification actions rather than entire business portfolios are examined, an inverted curvilinear association between diversification relatedness and performance is likely to emerge. This pattern is observed in both acquisitions and joint ventures. However, the association between diversification relatedness and performance in acquisitions is moderated by the level of industry adversity, though factors such as corporate coherence and heterogeneous experience do not moderate the association between diversification relatedness and performance. This study augments the body of knowledge on diversification and adds refinement to the traditional curvilinear finding regarding relatedness. By studying acquisitions and joint ventures independently, the results reveal differences in both slope and inflection points that suggest the relative impact of relatedness may vary depending on the mode of diversification.

The independent and joint effects of skill and physical bases of relatedness in diversification of organisations listed in the industrial sector of the JSE

Tshivhase, Konanani Morwagadi 11 August 2012 (has links)
Diversification is an important strategic alternative commonly used by organisations in pursuit of different markets and greater returns. Within the resource based view, (Collins&Montgomery, 2005) suggest that an effective diversification strategy can only be conducted if there is a fit between resources and the business opportunity so that resources contribute to competitive advantage.A quantitative research methodology was followed whereby organisations listed within the Industrial sector of the Johannesburg Securities Exchange (JSE) were categorized as diversified from period 2000 to 2010. The study empirically examined the independent and joint relationship between physical and skill base of relatedness against three financial measures in the form of hypotheses, to determine which base of relatedness influenced better performance.All three bases of relatedness had no significant effect on organizational financial performance. The findings refine our understanding of relatedness as a multidimensional concept and suggest that to have a more comprehensive evaluation of corporate diversification and its value in boosting company performance, a matrix of interrelationships across lines of business, activities, resources, industry effects and many more variables should be considered. / Dissertation (MBA)--University of Pretoria, 2012. / Gordon Institute of Business Science (GIBS) / unrestricted

A reservoir urban living room- Increasing water relatedness in Marabastad

Mphaka, Mamofella January 2020 (has links)
This dissertation aims to investigate how architecture can improve water literacy and, thus, water conservation and security, by bringing the user closer to the building’s water processes and systems. The programmatic function of the building is an urban living room. Here, the dwellers of the adjacent social housing development – about 3000 people – will be provided amenities for mostly recreational purposes. Furthermore, the tens of thousands of people who travel into Pretoria CBD daily for various government services, will be provided with a place to pause, linger, and perhaps have something to eat. The architectural exploration aims to empower the user through the provision of basic water services and surrounding secondary services, whilst at the same time enhancing the everyday user’s relationship with, and reverence of, water. The two main water resources that will be focused on are rain roof water and storm water. In an urban context where storm water runoff is currently treated as a destructive force and the water is discarded as quickly as possible from the city, the project will endeavor to harness this resource and utilise it to enhance the architecture. Similarly, roof rainwater will also be collected and utilised. The project will invite water into the building in various ways that enhance the climatic conditions within the building. Unlike in the traditional manner of waterproofing and keeping the water out of the building, these enhancing processes will be made visible to the users of the building in order to increase their understanding. This dissertation endeavors to add to the large body of research into the global quest for water security, underpinning itself in the context of the Marabastad, Pretoria. / Mini Dissertation (MArch(Prof))--University of Pretoria, 2020. / Architecture / MArch (Prof) / Unrestricted

An Examination of the Relatedness Needs of Adult Swimmers

Loose, Deward Warren 15 July 2009 (has links) (PDF)
The purpose of this study was to first examine the role of coaches, peers, and significant others in the development of relatedness as it applies to the motivation of adult Master swimmers, and second to develop recommendations for coaches. The participants in this study were 87 Masters swimmers from the Wasatch Front region of Utah in the counties of Davis, Weber, Utah, Wasatch, Salt Lake, and Summit. Participants in this study were registered members of United States Masters Swimming(USMS) and were spread across eleven age-group classifications in five-year increments and ranging in age from 18 to 74. There were 43 adult males and 44 adult females that participated in completing an open-ended response questionnaire. The results of this study show that relatedness, fostered by coaches, peers and significant others, plays a key role in getting and keeping adult Masters swimmer in the water to train and compete.
