Christian kinship : relatedness in Christian practice and moral thought

Torrance, David Alan January 2017 (has links)
Ideas of kinship play a significant role in structuring everyday life, and yet kinship has been neglected in Christian ethics, as well as moral philosophy and bioethics. Attention has been paid in these disciplines to the ethics of ‘family,’ but little regard has been paid to the fact that kinship is not a given, but is culturally contingent. The thesis seeks to remedy the neglect in recent Christian theological ethics by drawing on resources from the history of Christian thought and practice. It uses social anthropology both to unsettle the accounts of kinship used in Christian ethics, and to expose elements in Christian traditions of thought and practice relating to kinship. Notions of shared bodily substance, the house, gender and personhood recur cross-culturally in giving shape to kinship. By examining these four notions as they inform Christian thought and practice, a theological account is developed. Chapters dedicated to each of these four attempt to provide, in the first instance, a descriptive account of how the notion has structured Christian thought and practice in relation to kinship. Each chapter then turns, in the second instance, to a critical mode, offering a theological treatment of the chapter topic as it bears on kinship. The thesis concludes that kinship in Christ should be considered normatively primary for the Christian, but also that there are ways in which Christians have honoured this kinship in Christ by organising and playing out kinship on a smaller scale. In detailing the distinctively Christian organising principles that structure some practices of kinship ‘in miniature,’ another common practice – the special privileging of the blood tie in structuring kinship – is singled out for critique.

中文名詞多義性與詞彙認知歷程 / Multiple Senses of Mandarin Chinese Nominals: Implications for Lexical Access

林千哲, Lin, Chien-Jer Charles Unknown Date (has links)
本論文以語意學、認知語言學及心理語言學的觀點,探討中文名詞的多義現象。本篇論文討論詞彙多重意義的語言及心理語言表徵,並研究詞義如何在心理詞彙庫中被擷取。 文中藉由認知語言學者Tuggy(1993)所提出的認知語意架構,及詞彙語意學中「同形異義詞(homonymy)」、「一詞多義(polysemy)」及「模糊意義(vagueness)」等觀念之區辨,探索詞義之本質。本文所談之意義(sense)根據Ahrens(1999)之定義有以下三個特性:(1)意義非轉喻(metonymy)或部分/全體(meronymy)之延伸,但可以是隱喻性延伸;(2)意義之間的延伸關係無法由在同類名詞中直接以規律獲得;(3)除非特意,一詞的不同意義不會在同一語境中同時出現。 針對詞彙辨識歷程的語意效應,本論文有三大研究主題--意義數目效應、意義相關性效應及相對意義頻率效應。各效應之預測如下:「意義數目效應」認為意義數目較多的詞彙在詞彙判斷作業(lexical decision tasks)中比較容易辨識;「意義相關性效應」認為當一個詞的意義之間的相關性較高時,該詞的辨識時間亦會較快;「相對意義頻率效應」則認為一個詞意義之間頻率差異程度越小,該詞越有歧義之特質,也因此越容易辨識。 本研究旨在以實證方式探討這些語意向度在詞彙辨識歷程中所扮演的角色。由受試者提供200個中文名詞的意義並決定意義間的相關性;進行電腦詞彙判斷作業,得到辨識每個詞所需的反應時間;再由統計考驗反應時間來驗證各效應。 本研究結果發現只有「意義數目效應」達顯著水準,意義數目較多的詞彙在詞彙判斷作業中比較容易辨識。此一效應支持心理詞彙庫的隨機觸接模型(random access model)及平行觸接模型(parallel access model)並駁斥「序列搜尋模型(serial access model)」。 / This thesis studies the multiple senses of Chinese nominals from semantic, cognitive linguistic, and psycholinguistic viewpoints. It discusses the linguistic and psycholinguistic representations of a word's multiple senses, and the access of these senses in the mental lexicon. The nature of lexical meaning is examined by discussing lexical semantic notions such as homonymy, polysemy, and vagueness, and by introducing Tuggy's (1993) cognitive linguistic representation of a word's multiple lexical meanings. The "senses" of a word are defined according to the lexical semantic theory of Ahrens (1999) as having three properties: (1) A sense is not an instance of metonymic or meronymic extension, but may be an instance of metaphorical extension. (2) The extension links between two senses cannot be inherited by a class of nouns. (3) Senses cannot appear in the same context (unless the complexity is triggered). This thesis specifically looks into three semantic effects on word recognition, including the word's number-of-sense (NOS) effect, the effect of sense relatedness, and the effect of relative sense frequency. The predictions of these effects are as follows: The NOS effect predicts that words with more senses are recognized faster than those with fewer senses. The effect of sense relatedness predicts that words with more closely related senses are easier to recognize than those with distantly related senses. The effect of relative sense frequency predicts that words with equal sense frequencies are more easily recognized than words with unequal sense frequencies. This research aims at empirically verifying these three effects during the recognition of isolated lexical items. Subjects generate the senses of 200 Chinese nominals, and rate the relatedness among these senses. Lexical decision tasks are conducted to obtain the reaction times required to recognize each stimulus item. The semantic effects are verified by comparing the reaction times of different groups of experimental stimuli. The experimental results confirm only the NOS effect, giving support to the random and parallel access models of lexical access, and refuting the serial access model of the mental lexicon.

Measuring Semantic Distance using Distributional Profiles of Concepts

Mohammad, Saif 01 August 2008 (has links)
Semantic distance is a measure of how close or distant in meaning two units of language are. A large number of important natural language problems, including machine translation and word sense disambiguation, can be viewed as semantic distance problems. The two dominant approaches to estimating semantic distance are the WordNet-based semantic measures and the corpus-based distributional measures. In this thesis, I compare them, both qualitatively and quantitatively, and identify the limitations of each. This thesis argues that estimating semantic distance is essentially a property of concepts (rather than words) and that two concepts are semantically close if they occur in similar contexts. Instead of identifying the co-occurrence (distributional) profiles of words (distributional hypothesis), I argue that distributional profiles of concepts (DPCs) can be used to infer the semantic properties of concepts and indeed to estimate semantic distance more accurately. I propose a new hybrid approach to calculating semantic distance that combines corpus statistics and a published thesaurus (Macquarie Thesaurus). The algorithm determines estimates of the DPCs using the categories in the thesaurus as very coarse concepts and, notably, without requiring any sense-annotated data. Even though the use of only about 1000 concepts to represent the vocabulary of a language seems drastic, I show that the method achieves results better than the state-of-the-art in a number of natural language tasks. I show how cross-lingual DPCs can be created by combining text in one language with a thesaurus from another. Using these cross-lingual DPCs, we can solve problems in one, possibly resource-poor, language using a knowledge source from another, possibly resource-rich, language. I show that the approach is also useful in tasks that inherently involve two or more languages, such as machine translation and multilingual text summarization. The proposed approach is computationally inexpensive, it can estimate both semantic relatedness and semantic similarity, and it can be applied to all parts of speech. Extensive experiments on ranking word pairs as per semantic distance, real-word spelling correction, solving Reader's Digest word choice problems, determining word sense dominance, word sense disambiguation, and word translation show that the new approach is markedly superior to previous ones.

An exploration of South African diversity dynamics

Pretorius, Marius 30 November 2003 (has links)
Diversity has, over the last few decades, become a burning issue on the agenda of most companies. Current diversity-related interventions are mainly based on behaviouristic and socio-cognitive approaches. In this research diversity was approached from the systems psychodynamic paradigm. The general aim was to gain an understanding of the diversity dynamics that manifests in an South African diversity experience. The literature review focussed on diversity in the workplace, on the group relations training model, and on the application of the group relations training model to diversity. Qualitative research was done by interviewing a sample of 15 delegates who attended the November 2000 Robben Island Diversity Experience. These unstructured interviews were used to obtain in-depth information about the participant's experience and the data was analysed hermeneutically. The emerging themes were `crossing the boundary, engage the new world, the ties that bind, being imprisoned, the struggle, the road to reconciliation, integration and healing, back to the future and the crucible'. It is recommended that South African organizations make more use of the systems psychodynamic approach to study the manifestations of diversity dynamics. The aim is not to replace the other approaches to diversity, but to add a perspective that can enhance awareness and sensitivity to the covert, unconscious and irrational forces that impact on diversity. / Industrial and Organisational Psycology / M.

Drug addiction as a problem-determined system : a case study

Prinsloo, Melanie 11 1900 (has links)
The purpose of this study was to gain a better understanding of how a problem-determined system developed around a case of drug addiction within the context of a system of relatedness. The epistemological framework informing this qualitative study was constructivism. The six participants who took part in the study represent the most prominent role players in the particular context of living. The individual battling with drug addiction, his parents, older sister, maternal grandmother and maternal aunt were interviewed. The methods of data collection employed were semi-structured interviews, a family-chronological event chart, genograms, and an eco-map. The interviews were interpreted using the hermeneutic approach. The different themes that emerged from each participant’s story were integrated in relation to each other and with respect to the collaborative sources of data. The most dominant themes extracted within this study are the initial reactions to Andrew’s drug addiction, life changes experienced due to Andrew’s drug addiction, support, as well as the meanings attributed to Andrew’s drug addiction. Further research into problem-determined systems in different cultures is recommended. / Psychology / Thesis (M.A. (Clinical Psychology)) Psychology

Interakce rostlin a půdy a další faktory ovlivňující invazivnost rostlin / Interaction of plants and soil and other factors affecting plant invasiveness

Aldorfová, Anna January 2019 (has links)
Plant invasions represent a major ecological and socio-economical issue and understanding the drivers as well as consequences of plant invasions is thus one of the main goals of plant ecology. It is equally important to reveal general patterns underlying plant invasions and to understand the details of biology of individual invaders. In this thesis I explored plant-soil feedback (PSF) as a possible general mechanism underlying plant invasiveness, and also focused in detail on drivers and consequences of Impatiens parviflora invasion. The aims of this thesis were to i) assess the differences in intraspecific PSF between invasive and alien non-invasive species using a large set of species; ii) explore the relationship between PSF, residence time and phylogenetic novelty of the alien species; iii) compare the importance of PSF and other plant characteristics for plant invasiveness; iv) compare PSF between invasive and native congeners of similar level of dominance in the field; v) evaluate the effect of cultivating conditions on results of PSF experiments; vi) describe invasion dynamics and determine factors affecting spread of invasive I. parviflora using a method of monitoring its natural spread in several types of habitats, and vii) assess the impact of I. parviflora on native vegetation of oak-...

L’expérience de soin vécue par des infirmières de soins intensifs avec des patients cérébrolésés et leurs proches lorsque l'arrêt de traitement devient une option

Dollé, Stéphanie 12 1900 (has links)
Les expériences de soin vécues par les infirmières de soins intensifs auprès des patients cérébrolésés et de leurs proches alors que l’arrêt de traitement devient une option confrontent les infirmières à des défis qui surgissent particulièrement lors de l’instauration de la relation de soin, infirmière-patient, et lors de la mise en action de leur rôle d’avocate. Parmi les théories en sciences infirmières, celle du Human Caring de Watson (1979/1985/2008/2012) positionne la relation avec le patient, une relation transpersonnelle, comme un idéal moral. Dès lors, lorsqu’elles sont confrontées à des défis pour développer cette relation, les infirmières remettent en question tant leur pratique, que la conception qu’elles ont de la nature du soin, centre d’intérêt de leur discipline. Toutefois, à ce jour, très peu d’études ont eu pour objet de recherche la compréhension de cette expérience de soin vécue par des infirmières auprès de patients cérébrolésés et de leurs proches alors que l’arrêt de traitement devient une option. Cela, même si les défis, et les questionnements qu’ils suscitent chez les infirmières peuvent avoir d’importantes répercussions pour les personnes soignées dans un environnement de soins intensifs. Instruite par le constructivisme projectif, la pensée complexe de Morin et la philosophie de la compréhension de Ricœur, notre étude a eu pour but précisément de chercher à décrire et comprendre l’expérience de soin vécue par des infirmières de soins intensifs auprès de patients cérébrolésés et leurs proches lorsque l’arrêt de traitement devient une option. Cette recherche a été réalisée à partir d’un devis descriptif interprétatif, tirant ses origines de la discipline infirmière, en s’inspirant du Narrative Inquiry, méthode qui a pour visée d’étudier l’expérience (Chase, 2005; Clandinin & Connelly, 2000). Onze infirmières provenant des régions de Montréal et de Québec ont participé. La chercheuse a rencontré chaque participante à trois reprises pour effectuer le recueil des données à partir desquelles les récits de recherche ont été co-construits, et le premier niveau d’analyse a été réalisé. Cette analyse qui demeurait descriptive s’est poursuivie par questionnement analytique (Paillé & Mucchielli, 2012) de conception complexe en dialogue avec les 11 récits de recherche. Les connaissances construites en deux étapes, une phase descriptive et une phase interprétative sur cette expérience de soin ont constitué les fondements de notre réflexion pour activer la conception de nouvelles connaissances disciplinaires sur l’ontologie du soin. Nous avons interprété que le soin, que nous qualifions d’humanéthique, peut être conçu dans le construit d’un système complexe ouvert, comportant : une finalité, la vie bonne avec et pour un patient heureux; une écologie dans laquelle il s’organise, où l’environnement social est prépondérant; une évolution temporelle se déployant dans un espace-temps; une reliance indicible, la dimension relationnelle essentielle au soin; mais aussi une part d’incertitude. Une modélisation du soin humanéthique, un système perçu complexe, est présentée à travers un récit s’inspirant de la pratique infirmière. Dans cette étude, le récit s’est révélé être un outil pertinent, car la narrativité a non seulement contribué à questionner et réfléchir la pratique lors du recueil des données, et de l’analyse; mais elle a aussi permis de réaliser une représentation dynamique et pragmatique des résultats empiriques et théoriques. Ainsi, notre projet à travers l’approfondissement d’expériences vécues en pratique par des infirmières a conduit à l’avancement d’un nouvel éclairage théorique sur le soin. De plus, à travers un récit, nous avons proposé des leviers qui puissent être actionnables en pratique par les infirmières, quel que soit le contexte dans lequel le soin se déroule. Des pistes de réflexion et des implications en ont résulté pour les secteurs de la pratique clinique, de la formation, de la gestion et de la recherche en sciences infirmières. Dès lors, cette étude orientée vers la pratique a non seulement la faculté de pouvoir soutenir la pratique infirmière, mais aussi d’être à l’origine de nouveaux questionnements sur la nature du soin, permettant ainsi de poursuivre son développement. / The care experiences of critical care nurses with brain-damaged patients and their loved ones as withdrawing treatment becomes an option confront nurses with challenges that arise particularly when establishing the nurse-patient care relationship and when putting their advocacy role into action. Among the nursing theories, Watson's Human Caring (1979/1985/2008/2012) positions the relationship with the patient, a transpersonal relationship, as a moral ideal. Therefore, when faced with challenges in developing this relationship, nurses question both their practice and their understanding of the nature of care, which is the focus of their discipline. However, to date, very few studies have focused on understanding nurses' experience of caring for brain-damaged patients and their loved ones as withdrawing treatment becomes a care option. This is despite the fact that the challenges, and the questions they raise for nurses, can have important implications for those being cared for in a critical care environment. Based on projective constructivism, Morin's complex thinking and Ricoeur's philosophy of understanding, the purpose of our study was precisely to seek to describe and understand the care experience of critical care nurses with brain-damaged patients and their families when withdrawing treatment becomes an option. This research was carried out from an interpretative descriptive specification, drawing its origins from the nursing discipline, inspired by the Narrative Inquiry, a method that aims to study the experience (Chase, 2005; Clandinin & Connelly, 2000). Eleven nurses from the regions of Montreal and Quebec City participated. The researcher met with each participant three times to carry out the data collection from which the research narratives were co-constructed, and the first level of analysis was carried out. This analysis, which remained descriptive, continued through analytical questioning (Paillé & Mucchielli, 2012) of complex design in dialogue with the 11 research narratives. The knowledge built up in two stages, a descriptive phase and an interpretative phase on this experience of care constituted the foundations of our reflection to activate the conception of new disciplinary knowledge on the ontology of care. We have interpreted that the care, which we call “humanethical”, can be designed in the construction of a complex open system, with: a purpose, a good life with and for a happy patient; an ecology in which it is organized, where the social environment is preponderant; a temporal evolution unfolding in space-time; an unspeakable relatedness , the relational dimension essential to care; but also an element of uncertainty. Modelling the “humanethical” care, a complex system, is presented through a narrative inspired by nursing practice. In this study, storytelling proved to be a relevant tool, as narrativity not only helped to question and reflect on practice during data collection and analysis, but also provided a dynamic and pragmatic representation of empirical and theoretical findings. Thus, our project through the deepening of experiences lived in practice by nurses has led to the advancement of a new theoretical perspective on care. In addition, through a narrative, we have proposed levers that can be operated in practice by nurses, regardless of the context in which the care takes place. This led to a number of reflections and implications for clinical practice, education, management and research in nursing. Therefore, this practice-oriented study not only has the potential to support nursing practice, but also to raise new questions about the nature of care, thus enabling its further development.

[pt] GERAÇÃO AUTOMÁTICA DE CONEXÕES PARA GESTÃO DE CONHECIMENTO / [en] ON AUTOMATIC GENERATION OF KNOWLEDGE CONNECTIONS

FELIPE POGGI DE ARAGAO FRAGA 10 November 2022 (has links)
[pt] Recentemente, o tópico de Gestão de Conhecimento Pessoal vem ganhando muita popularidade. Ilustrado pelo rápido crescimento de aplicativos como Notion, Obsidian, e Roam Research e da aparição de livros como How to Take Smart Notes e Building a Second Brain. Contudo, ainda é uma área que não foi fortemente envolvida pelo Processamento de Linguagem Natural (NLP). Isso abre uma bela oportunidade para a aplicação de NLP em operações com conhecimento. Nosso objetivo é o desenvolvimento de um sistema de software que utiliza NLP e aplicatovps de anotação para transformar uma coleção de textos isolados em uma coleção de textos interconectada e inter-navegável. Isso é feito usando mecanismos de navegação baseados em conceitos mencionados e recomendações semânticas. Neste trabalho apresentamos a metodologia para construir o sistema, demonstrações com exemplos palpáveis, assim como uma avaliação para determinar a coerência dos resultados. / [en] Recently, the topic of Personal Knowledge Management (PKM) has seen a surge in popularity. This is illustrated by the accelerated growth of apps such as Notion, Obsidian, and Roam Research, and the appearance of books like How to Take Smart Notes and Building a Second Brain. However, the area of PKM has not seen much integration with the field of Natural Language Processing (NLP). This opens up an interesting opportunity to apply NLP techniques to knowledge operations tasks. Our objective is the development of a Software System that uses NLP and note-taking apps to transform a siloed text collection into an interconnected and inter-navigable text collection. The system uses navigation mechanisms based on shared concepts and semantic relatedness between texts. In this study, we present a methodology to build this system, the research context, demonstrations using examples, and an evaluation to determine if the system functions properly and if the proposed connections are coherent.

The evolution of social behaviour : the effect of mating system and social structure in the European badger Meles meles

Dugdale, Hannah L. January 2007 (has links)
Studies of mating systems and social organisation have been central to understanding of the evolution of social behaviour. The European badger Meles meles is a good species in which to study these processes, as its complex social system provides an opportunity to investigate how both natural and kin selection shape the evolution of mating systems and social structure. In this thesis, I use behavioural and genetic data to describe the mating system and social organisation of a high-density badger population and examine the occurrence of cooperative breeding. I genotyped 915 (85%) badgers trapped in Wytham Woods (1987–2005), 630 of which were cubs, and assigned both parents to 331 cubs with 95% confidence. This revealed a polygynandrous mating system, with up to five mothers and five fathers per social group. Mounting behaviour was also polygynandrous and I show the strongest evidence to date for multiple-paternity litters. I demonstrate, for the first time, that groups consisted of close and distant kin: approximately one third of group members were first-order kin, and overall group members had slightly lower relatedness levels than half-siblings. Within groups, adult and yearling females had higher pairwise relatedness than males, and neighbouring groups contained relatives. These findings result from the high level (42%) of extra-group paternities, 86% of which were assigned to neighbouring males. For the first time I show that females avoided inbreeding by mating with extra-group males; however, incestuous matings did occur. Promiscuous and repeated mountings were observed, which may reduce male–male aggression and infanticide, but may also promote sperm competition, genetic diversity, and / or genetic compatibility. Just under a third of adult males and females were assigned parentage each year and I quantify, for the first time, reproductive skew within badger groups. Correlations between relatedness, group productivity, and reproductive skew were not consistent with the predictions of incomplete-control models; rather, resource availability may play a role. Older and younger badgers displayed reduced annual breeding success, with male success increasing initially with experience. The Restraint, Constraint, and Selection Hypotheses did not explain the age-related breeding pattern in females. Variance in lifetime breeding success (LBS) was greater for males. Males that only bred within or only outside of their groups had half the LBS of males that did both. Females that were assigned maternity probably bred cooperatively and allonursed non-offspring, which has not been demonstrated previously. No benefit was established, however, in terms of litter size, probability of offspring breeding, or offspring lifetime breeding success, with more mothers in a group. In conclusion, badger social groups are fostered through kinship ties. Polygynandry and repeated mounting may have evolved originally to reduce male–male aggression and infanticide by males, through paternity masking. Although plural breeding occurs, group living appears to be costly. Motivation to disperse may be reduced through high-levels of extra-group paternities, which may also reduce inbreeding. Cooperative breeding among mothers may represent a low-cost behaviour with indirect benefits due to high levels of relatedness between female group-members. Badger sociality therefore represents an early stage in the evolution of social behaviour.
