This study sets out to demonstrate the usefulness of cybernetic description for grief therapy, specifically the field parental loss of a child. This paradigm was used to facilitate an alternate mode of conceptualisation, one engendering a more encompassing, aesthetic view. The following core cybernetic concepts were used: punctuation, complementarity, pattern and metapattern forming the framework of cybernetic description as applied. A literature study attempting to merge the gestalt of cybernetic description with that of bereavement theory, specifically that pertaining to the parental loss of a child, is presented. A single case study is described illustrating how cybernetic description is applied to the grief narrative. Arising out of this, the implications of cybernetic description for the field of grief and social work in general are outlined. / Social Work / M.A. (Social Science (Mental Health))

Text in Afrikaans / Die komplementariteit tussen afstand en intimiteit in die terapeutiese verhouding word ge"illustreer en bespreek aan die hand van 'n enkeie gevallestudie. Die klem is op rekursiewe en selfverwysende prosesse wat tussen die terapeut en kiient plaasvind, sodat die vvyse waarop intiemer en meer afstandelike interaksies ge-kokreer is, uitgelig word. Die terapeutiese proses word binne die raamwerk van die ekosistemiese en sosiale konstruksionistiese epistomologie bespreek. Navorsing word uitgevoer volgens die naturalistiese navorsingsparadigma en raakpunte tussen die navorsingsparadigma en epistomologie wat bespreek is, word aan die hand van die gevaliestudie ge"illustreer. In die studie word daar ook verwys na verwante kwessies, soos aanraking en grense in die terapeutiese verhouding, terapie as 'n a-sosiale konteks, terapie as 'n paradoksale situasie en die neutraliteit van die terapeut, wat aansluit by die tema van hierdie studie. Hierdie temas word geintegreer tydens die bespreking van die gevallestudie. / An individual case study is used in this study, to discuss the complementarity between distance and intimacy in the therapeutic relationship. The focus is on recursive and selfreflective processes between the therapist and the client in order to explain the way in which intimate and distant interactions were coconstructed. The therapeutic process was discussed in the context of ecosystemic and social constructionist epistemologies. Research was done according to the principles of the naturalistic research paradigm and overlaps between this research paradigm and epistemologies that were discussed are brought forward through the discussion of the case study. There are also references in this study to related issues, such as touching and boundaries in the therapeutic relationship, therapy as an a-social and paradoxical context, and the neutrality of the therapist, which connect with the theme of this study. These themes are integrated in the discussion of the case study. / Psychology / M.A. (Kliniese Sielkunde)

Afrikaans text / Die doel van hierdie navorsing is om lewenssin soos dit binne die leefwereld van die gesitueerde Suid-Afrikaanse sakepersoon van toepassing is, teoreties te omlyn, te operasionaliseer en die belewenis daarvan op fenomenologiese wyse te beskryf. Lewenssin, met lewenssinvolheid en lewenssinloosheid as twee pole op 'n kontinuum, is ondersoek deur te fokus op lewensorientasie, lokus van gedrag, waardes, spiritualiteit, groei, ontwikkeling, transendering, vervreemding, 'n kortstondige en fatalistiese ingesteldheid, konformisme, kollektivisme, fanatisme, en die strewe na mitiese sukses. In die literatuurondersoek, wat die eksistensiele, humanistiese en holistiese paradigmas as vertrekpunte neem, is operasionele definisies van lewenssinvolheid en lewenssinloosheid gekonstrueer. Die profiel van die Suid-Afrikaanse sakepersoon met so 'n belewenis is aan die hand van sy/haar paradigma, kenmerke en gedrag gekonstrueer. 'n Proses van meaning making word voorgehou, terwyl lewenssin as integrasie van teenoorgesteldes gekonstrueer word. Daar word gepostuleer dat die sakepersoon met 'n belewenis van lewenssinvolheid die landskap van sy/haar psige relasioneel bewoon. Daarteenoor openbaar 'n belewenis van Jewenssinloosheid 'n nie-relasionele orientasie, paradigma en bewoning van die wereld. In die fenomenologiese ondersoek is gebruik gemaak van die onderhoud om die fenomeen, lewenssin, te laat ontvou. Die steekproef het bestaan uit getroude sakelui, dertig jaar en ouer, en woonagtig in Gauteng. Heterogeniteit in terme van geslag, geloofsoortuigings en korporatiewe opset is ook verreken. Uit die ondersoek ontvou ses temas wat sentreer om ruimtelikheid, basiese stemming, beliggaming en bewoning, asook die teenwoordigheid van die psige, andere en die wereld (wat die aarde en 'n transpersoonlike entiteit insluit). Dit blyk dat die Suid-Afrikaanse sakepersoon sy/haar landskap vera! nie-relasioneel bewoon. Elemente van relasionele bestaan is wei aanwesig. Tog word die begeerte aan 'n meer relasionele bestaan in die behoeftes en versugtinge van die betrokke sakelui verwoord. Die gevolgtrekking word gemaak dat gebrekkige relasies in verband gebring kan word met 'n nie-relasionele paradigma wat lewenssinloosheid tot gevolg het. Op 'n kontinuum van lewenssin word bevind dat Suid-Afrikaanse sakelui nader aan die pool van lewenssinloosheid le, met 'n behoefte aan 'n beweging na die teenoorgestelde pool, naamlik lewenssinvolheid. Om lewenssinvolheid, lewenskwaliteit, en optimaliteit te bevorder, word aanbeveel dat die relasionele paradigma as vertrekpunt dien by remedierende ingrepe. / The purpose of this research is to theoretically outline and operationalise meaning in life as it applies to the life-world of situated South African businesspersons, and to describe phenomenologically their experience of that phenomenon. integration of opposites. It is posited that the businessperson experiencing life as meaningful, inhabits the landscape of his/her psyche in a relational way. In contrast, the person experiencing life as meaningless, displays a non-relational orientation, paradigm and being-in-the­ world. The phenomenological investigation made use of interviews to allow the phenomenon, meaning in life, to unfold. The sample consisted of married business persons, thirty years and older, and residing in Gauteng. Heterogeneity (in terms of gender, religious convictions and corporate circumstances) was also taken into account. Meaning, with meaningfulness and meaninglessness as its two extremes on a continuum, was examined, focusing on life orientation, engagement style, values, spirituality, growth, development, transcending, alienation, transitoriness and fatalism, conformism, collectivism, fanaticism, and aspiring to mythical success. In the literature investigation, which was based on existential, humanistic and holistic paradigms, operational definitions of meaningfulness and meaninglessness were construed. The profile of the South African businessperson experiencing the phenomenon, was construed with reference to his/her paradigm, characteristics and conduct. A meaning making process is proffered, while meaning is construed as an Six themes unfold from the investigation, centring around spatiality, basic mood, human bodiliness and being-in-the-world, as well as the presence of the psyche, other people and the world (including the earth and a transpersonal entity). The South African businessperson appears to inhabit his/her landscape in a mainly non­ relational manner. There are some elements of relational existence, but the needs and heart's desires voiced by the businesspersons concerned point to a longing for a more relational existence. In conclusion: Deficient relations can be associated with a non-relational paradigm, which causes an experience of life as meaningless. A meaning continuum shows South African businesspersons as figuring closer to meaninglessness, and needing to move towards the opposite pole, namely meaningfulness. To promote meaningfulness, quality of life and optimal functioning, the relational paradigm is recommended as point of departure in remedial intervention. / Industrial and Organisational Psychology / DCom (Bedryfsielkunde)

This study is geared at an open systems critique of the macro theories of development. It is highlighted in this study that we are living through the realities of the open systems, and yet much of development thought is based on closed systems philosophies, principle and ideologies. The first chapter gives an orientation into the origins of both the closed systems and open systems paradigms respectively. Included in this orientation chapter, is the literature review of the various research contributions of the major trends in development thought. The second chapter expands on the evolution of the closed systems paradigm and its influences on development thought. This chapter further explains the attendant philosophies, principles and ideologies that underlie the closed systems paradigm. The third chapter captures the open systems paradigm and its influences on contemporary development discourse. Further to the discussion on the closed systems paradigm, the chapter elaborates on the philosophies, principles and processes that underlie this paradigm. The fourth chapter is on a discussion of trends in development thinking, traced from the traditional, through the medieval to the modern, right up to the contemporary. This entails tracing the theory to its ontological background right up to its implications for social reality in contemporary development thought and experience. The fifth chapter is on the open systems critique of the trends in development thinking, while the sixth chapter revisits the open systems paradigm and its implications for development thought. In the seventh chapter is the recapitulation of the findings in the study and recommendations for both development thought and practice. / Public Administration and Management / D. Litt. et Phil.

An increasing number of reports indicate that managers are opposed to performance appraisal. It is important to understand why managers have favourable or unfavourable attitudes towards performance appraisal and it is necessary to investigate the causing factors of these attitudes. The aim of this research was therefore to gain a deeper understanding of the factors that influence managers’ attitudes towards performance appraisal. This study was conducted within the interpretive research paradigm and situated in a medium-sized organisation within the financial services industry. The sample was purposefully selected and the data were collected through in-depth interviews and naïve sketches. The data were analysed applying Tesch’s descriptive analysis method. The main findings indicated that managers who needed to conduct performance appraisals perceived and experienced performance appraisal as an uncomfortable and emotional process that might cause them to become defensive. Moreover, it was revealed that the managers experienced uncertainties about aspects of performance appraisal, such as the purpose of performance appraisal, what must be measured and frequency of performance appraisal. As a result of such uncertainties, managers might not always have the ability or readiness to conduct performance appraisals, especially when the performance appraisal contains negative performance feedback. Furthermore, the organisational context might put managers in an undesirable situation to distort performance ratings of employees in order to achieve organisational goals or the manager’s personal goals, which in turn influence the attitude of the manager. The findings of the study can assist organisations in influencing managers’ attitudes more positively and in enhancing the overall performance appraisal process. / Industrial and Organisational Psychology / M.

We have demonstrated that the production of subjectivity is the base industry of this period e the breaking possible points found by Guattari that have been possible by the technological advancements and the forms of social organization of this period. Before the massification and homogenization of subjectivity production the guattarian theory propose a singular and autonomy production from a ethic-esthetic paradigm based on his concept of ecosophy that propose an articulation ethic-politic of subjectivity, social and environment. The subjectivity is machinic it means that it is a production from socius through heterogenic elements such as social relations, technological and invisible machines, aesthetic field, the economy, the politics etc. Through the concepts of micro-politics, autopoiesis and post-media we saw how a production of subjectivity can be more close to autonomy and singularity / A presente pesquisa se propôs a dois objetivos principais: 1) Um geral, que será expor o conceito de subjetividade maquínica de Felix Guattari; 2) e um outro, mais específico, que pretende analisar as contribuições deste conceito para uma compreensão mais social e ampla da subjetividade, levando em consideração a heterogeneidade não-humana, maquínica, desta produção, fato este que se evidencia fortemente no capitalismo pós-industrial. Mostramos como a produção de subjetividade é a indústria de base deste pe-ríodo e os pontos de ruptura possíveis encontrados por Guattari, proporcionados pelos avanços tecnológicos e as formas de organização social característicos deste período. Frente à massificação e homogeneização da produção de subjetividade, a teoria guatta-riana propõe uma produção singularizante e autônoma, a partir de um paradigma ético-estético, baseada em seu conceito de ecosofia, o qual propõe uma articulação ético-política da subjetividade, do social e do ambiental. A subjetividade é maquínica, ou seja, é produzida no socius através de elementos heterogêneos como as relações sociais, as máquinas tecnológicas, as máquinas incorporais, o âmbito estético, a economia, a política etc. Através dos conceitos de micropolítica, autopoiese e pós-mídia vimos as indicações de como é possível uma produção de subjetividade mais autônoma e singular.

O trabalho investigativo sustenta que a crise transita da esfera da produção à esfera da ciência pela categoria paradigma; e da ciência para educação por esta mesma categoria. A reversão do processo se dá através da pedagogia, da educação para ciência e produção. Conclui sustentando que o quadro de relações diante da crise atual se diferencia da lógica derivada das crises anteriores, dada a singularidade da crise atual, como crise orgânica da estrutura de valor, em que se assenta a relação capital e a sociedade em geral, portanto, exigindo uma revolução científica para a mudança de paradigmas, cujos limites se apresentam na crise do capital nos países do capitalismo avançado: EUA, União Europeia e Japão. A educação brasileira deve decidir: ou muda seus paradigmas ou caminha para a mesma situação de crise do capital dos países avançados.

This way the priority of this work, is a critic investigation about the essence of paradigm of “society of knowledge”, so as to reaffirm the centrality of work in confront at the misrepresent identification between “society of knowledge” and surmount of capital. In this perspective are collocated in debate some fundamentals questions: Is possible to demarcate historically the appearance of “society of knowledge”? What did change in social scenery that would answer for the elevation of relate society? Until that point the “society of knowledge” would indicate a direct vinculation with the structural crisis of Capital and the project of re-structuration of system? What perspectives sight the called “society of knowledge”? In other words, what the mean philosophic-politic of this paradigm? Where reside her ideologic force? To who interest this paradigm that not avalanche any “competence” directed to exercise of organization and of collective fight with objective of touch in the heart of a system which obvious destructivity menace to collocate a final point in human specie? What the fundaments, of this paradigm? Finally, would be this a new paradigm to serve the old order of Capital? This work has the objective of indicate the complex of factors of sphere of social totality that furnish the material base the revolt of ideology of “society of knowledge”, we appeal beyond of Marx, at the studies of critical thinkers in the present period, which productions can offer importants contributions to a analyze duly fundamental of terms and the philosophic and political means of the actual debate. To finish, the paradigm of “society of knowledge” is inside of the permanent movement, but intensed for structural crisis of Capital, of re-structuration of Capital / O presente trabalho, intitulado “Sociedade do conhecimento”: um novo paradigma em favor da velha ordem, possui caráter teórico-bibliográfico e pretende analisar sob uma perspectiva crítica, devidamente fundamentada na teoria marxiana da centralidade do trabalho na reprodução da vida humana, as vinculações determinantes entre o paradigma sócio-educacional da “sociedade do conhecimento” e o período de crise estrutural do capital, demonstrando, desta feita, o referido paradigma como um fenômeno da reprodução ideológica em favor do mercado como força organizativa central da vida humana. Desta forma é que priorizamos para a delimitação deste trabalho, uma investigação crítica acerca da essência do paradigma da “sociedade do conhecimento”, a fim de reafirmar a centralidade do trabalho em contraposição à falseada identificação entre “sociedade do conhecimento” e superação do capital. Por esse prisma, são postas em debate algumas questões fundamentais: É possível demarcar historicamente o surgimento da “sociedade do conhecimento”? O que mudou no cenário social que responderia pela elevação da referida sociedade? Até que ponto a “sociedade do conhecimento” indicaria uma direta vinculação com a crise estrutural do capital e a conseqüente empreitada de reestruturação do sistema? Para que horizonte aponta a propalada “sociedade do conhecimento”? Dito de outro modo, qual o significado filosófico-político desta categoria? Onde reside a força ideológica desse discurso? A que interesses serve um modelo que não alude a qualquer “competência” dirigida ao exercício da organização e da luta coletiva com vistas a tocar o coração de um sistema, cuja evidente destrutividade ameaça colocar um ponto final na história do gênero humano? Quais os fundamentos, sobre os quais se constrói a “sociedade do conhecimento”? Por fim, seria este um novo paradigma a serviço da velha ordem do capital? Com o objetivo de indicar o complexo de fatores da esfera da totalidade social que fornece a base material para a insurgência do ideário da “sociedade do conhecimento”, recorremos, além de Marx, aos estudos de pensadores críticos da atualidade, cujas produções podem oferecer relevantes contribuições para uma análise adequadamente fundamentada dos termos e do significado filosófico e político-pedagógico do atual debate.

Esta dissertação trata da relação entre as transformações contemporâneas que envolvem o conhecimento científico e tecnológico diante da disseminação das novas tecnologias da informação e da comunicação (NTICs) e as potencialidades de desenvolvimento de dinâmicas de saber não restritas aos pressupostos do paradigma da ciência moderna. O objetivo principal deste trabalho consiste na investigação dos limites e possibilidades para a emergência de distintas dinâmicas do conhecimento científico e tecnológico associadas aos novos ambientes virtuais surgidos no período da web 2.0. Especificamente são investigadas as potencialidades desses ambientes para a promoção de dinâmicas favoráveis à constituição de ecologia de saberes por seus integrantes. Para isso, busca-se identificar e analisar o conjunto de valores, interesses, representações e práticas que envolvem a organização formal e os processos de participação de um ambiente em especial da internet: a Wikipédia lusófona. Assume-se a ideia de que o site, constituído sob influência dos valores e práticas que deram forma à internet, é capaz de favorecer o desenvolvimento de dinâmicas de colaboração compatíveis com os pressupostos da ecologia de saberes propostos por Santos (2011a). Esta investigação foi realizada a partir da análise da estrutura “formal” wikipedista e da realização de entrevistas semiestruturadas envolvendo a participação de 24 usuários colaboradores em artigos de temática científica e tecnológica do “conteúdo destacado” da Wikipédia lusófona. Conclui-se, de um lado, que o site tende a reproduzir a hierarquia das disciplinas de C&T e a distribuição das áreas de interesse dos usuários de acordo com os espaços por eles ocupados na sociedade, bem como a manifestar valores, representações e práticas fortemente associados ao paradigma da ciência e da tecnologia modernas. De outro lado, entretanto, mostra-se se favorável não só à diversificação do perfil dos agentes voltados à produção, difusão e aquisição de conteúdos científicos e tecnológicos em comparação aos espaços convencionais do conhecimento de C&T, mas também à abertura de diferentes possibilidades de participação e de apropriação dos produtos coletivos do site. Da mesma forma, a Wikipédia lusófona revela-se capaz de incitar entre seus colaboradores o desenvolvimento da capacidade de argumentação, de convivência com diferentes pontos de vista e o interesse pelo trabalho voluntário, de modo a favorecer a emergência de representações imprescindíveis à superação do paradigma da ciência moderna e à constituição de ecologia de saberes: a solidariedade, a participação, o princípio do prazer, a autoria e a artefatualidade discursiva. / This thesis is about the relation between the contemporary transformations concerning scientific and technological knowledge because of the spread of new information and communication technologies (NICT) and the potentials of development of new knowledge’s dynamic not restricted to the assumptions of the modern science paradigm. The goal of this study is to investigate the limits and possibilities for the emergence of distinct dynamics of scientific and technological knowledge under the influence of the web 2.0 virtual interfaces. Specifically, the thesis investigates the potentials of those interfaces to promote, among their users, propitious dynamics toward the establishment of the ecology of knowledges. This research identifies and analyzes a set of values, interests, representations and practices concerning the formal organization and the participation’s processes of a particular web’s virtual interface: Lusophone Wikipedia. Assuming the hypothesis that this site, which has been founded under the influence of the same values and practices adopted in the internet creation, is able to promote the development of compatibles collaborative dynamics with the assumptions of an ecology of knowledges, as proposed by Santos (2011a). This investigation has been made from the analysis of "formal" Wikipedian’s structure and from semi-structured interviews with 24 collaborators users of the "highlighted subjects” on scientific and technological issues of the Lusophone Wikipedia. The thesis’ conclusions are: on one hand, that the Wikipedian’s interface tends to reproduce the disciplines’ hierarchy of the S&T knowledge and the distribution of users’ areas of interest according to the social places occupied by them, as well as express values, representations and practices associated with modern science paradigm. On the other hand, this study observes that Lusophone Wikipedia is propitious, not only to diversify the profile of the collaborators involved in the production, dissemination and achievement of scientific and technological subjects compared to the conventional spaces of the S&T knowledge, but also opening various possibilities for participation in the site, included ownership of collective products. In this way, this virtual interface can be able to foment among their collaborators the capacity of argumentation, coexistence with different points of view and the interest in voluntary work in order to foster the emergence of the essential representations to overcoming the modern science paradigm and the establishment of an ecology of knowledges: solidarity, participation, the principle of pleasure, authorship and discursive artifactuality.
