Konkurrenzbeziehungen: Allgemeine und konfessionelle Kunstvereine im Kunstfeld des 19. Jahrhunderts

Karstein, Uta 09 August 2024 (has links)
The article compares secular and faith-based art societies in the 19th century. Of special interest are the societies’ missions and purposes, as well as their activities and organizational structures. The main thesis is based on the work of German sociologist Georg Simmel and his conflict theory. I argue that the competition of these societies had invigorating effects on the field of art and its institutionalization in the course of the 19th century.

Krybusová, Klára January 2015 (has links)
The diploma thesis deals with the possibilities and limitations of the planning care and support to people with dementia. Diseases that lead to the dementia syndrome causing difficulties in almost all areas of life of the person who suffering from the syndrome. A person with dementia then requires specific approaches by others. The aim of this thesis is to identify the specifics of individual planning of social services with people with dementia and find out how is the individual planning with these persons done in selected homes with the special regime in the Capital City Prague and Central Bohemia.The first part provides an overview of current knowledge in the field of related topics. The second part contains the research which was carried in selected nine special regime homes in the Prague and Central Bohemia. In the research were used methods of semi- structured interviews and analysis of documents. In the research was found that the planning with people with dementia is in some aspects different from the planning with people without cognitive impairment. In this planning are more used methods that allow to establish contact with the client and identify and transmit information among employees. There was also found other specifics that are shown in the results section and at the end of this...

Abstract in English, Afrikaans and Setswana / The study was prompted by the decline in accounting enrolments and the ongoing criticism due to learners’ poor performance in the Accounting subject in South Africa. Given the increasing need for accounting graduates and, more importantly, qualified accounting professionals, this study investigated the preconceived perceptions participating high school learners in selected schools in the Mafikeng area had about the accounting profession at the time of this study. The study drew on a rich body of existing literature and adopted the social cognitive career theory of Lent, Brown and Hackett (1994) to explore the factors influencing career interests of learners in accounting as a career path. A quantitative research approach with a survey questionnaire, framed within a positivist paradigm, was used to elicit opinions from learners. The findings revealed that work satisfaction, earnings potential, self-efficacy, personal interest, offering Accounting as a subject and having an accountant in the family are among the factors that significantly influenced participating learners’ career interests in accounting. / Die studie is aangespoor deur die afname in rekeningkunde-inskrywings en die deurlopende kritiek van leerders se swak prestasie in rekeningkunde in Suid-Afrika. Gegewe die toenemende behoefte vir rekeningkundegegradueerdes en, meer belangrik, gekwalifiseerde rekeningkundepraktisyns, ondersoek hierdie studie die huidige vooropgestelde persepsies wat hoërskoolleerders in Suid-Afrika van die rekeningkundige beroep het. Die studie benut die omvattende bestaande literatuur en aanvaar die sosiaal kognitiewe loopbaanteorie van Lent, Brown en Hackett (1994) om die faktore te ondersoek wat die belangstelling van leerders in rekeningkunde as 'n loopbaanrigting beïnvloed. 'n Kwantitatiewe navorsingsbenadering met 'n opnamevraelys, binne 'n positivistiese paradigma, is gebruik om menings van leerders te ontlok. Die bevindings het gewys dat werksbevrediging, verdienstepotensiaal, selfwerksaamheid, persoonlike belang, die aanbied van rekeningkunde as 'n vak en 'n rekeningkundige in die gesin van die faktore is wat leerders se loopbaanbelangstelling in rekeningkunde beduidend beïnvloed / Thutopatlisiso e tlhotlheleditswe ke kwelotlase ya ikwadiso ya dithuto tsa Palotlotlo le go kgalwa go go tswelelang pele ga tiragatso e e bokoa ya barutwana mo Palotlotlong mo Aforikaborwa.

The state's legal responsibility for the social reintegration of sexually abused children / Kenny van Biljon

Van Biljon, Kenny January 2014 (has links)
Section 28(1)(d) of the Constitution guarantees a child the right to be protected against abuse. When a child’s constitutional rights are violated by an offender by means of sexual abuse and degradation, the state has a legal responsibility to restore that right. In determining whether the state is adhering to its legal responsibility to socially reintegrate sexually abused children, the Constitution, the VEP, the Victims’ Charter, the UPVM, legislation and one-stop centres were explored. It was found that none of these programs, charters and documents places an obligation on the state. Section 39(1)(b) of the Constitution states that the court must consider international law when interpreting the Bill of Rights. The CRC, ACRWC, United Nations Declaration of Basic Principles were studied. It was found that although South Africa is a signatory to everyone, it does not adhere to the principles stated in the respected document. Section 39(1)(c) of the Constitution states that the court may consider foreign law when interpreting the Bill of Rights. The dissertation does not consist of a comparative study. Each of Canada, Australia and New Zealand’s legislation was studied relating to compensation schemes in order to determine what lessons can be drawn from the three countries. It was found that each country has a unique compensation scheme. Although South Africa can learn from the way in which these schemes are administered and funded, the schemes of the three countries are not beyond critique. South Africa can therefore also take note of the negative aspects of the compensation schemes of the three countries so as to improve on it. It was found that through a literature study the state does not adhere to its legal responsibility to socially reintegrate sexually abused children. It is recommended that the state should consider implementing a state-funded compensation scheme to assist the children that have fallen victim to sexual abuse and degradation. / LLM, North-West University, Potchefstroom Campus, 2014

Aminopyrimidine derivatives as adenosine antagonists / Janke Kleynhans

Kleynhans, Janke January 2013 (has links)
Aims of this project - The aim of this study was to design and synthesise novel 2-aminopyrimidine derivatives as potential adenosine A1 and A2A receptor antagonists. Background and rationale - Parkinson’s disease is the second most common neurodegenerative disorder (after Alzheimer’s disease) and is characterised by the selective death of the dopaminergic neurons of the nigro-striatal pathway. Distinctive motor symptoms include bradykinesia, muscle rigidity and tremor, while non-motor symptoms, of which cognitive dysfunction is an example, also frequently occur. Current therapy provides symptomatic relief mainly by augmentation of dopaminergic signalling (levodopa, dopamine agonists, MAO and COMT enzyme inhibitors), but disease progression is not adequately addressed. New therapies that can prevent further neurodegeneration in addition to providing symptomatic relief are therefore urgently required. Adenosine has an important function as neuromodulator in the central nervous system. The adenosine A2A receptor in particular plays an essential role in the regulation of movement. This, coupled to the fact that it is uniquely distributed in the basal ganglia, contributes to its attractiveness as non-dopaminergic target in the treatment of movement disorders, such as Parkinson’s disease. The efficacy of adenosine receptor antagonists has been illustrated in animal models of Parkinson’s disease and several adenosine receptor antagonists have also reached clinical trials. The neuroprotective properties of adenosine A2A receptor antagonists are further attributed to their ability to modulate neuro-inflammation and decrease the release of the excitatory neurotransmitter glutamate, which is implicated in neurotoxicity. While adenosine A1 receptor antagonism has a synergistic effect on the motor effects of adenosine A2A receptor antagonism, it has the additional benefit of improving cognitive dysfunction, a cardinal non-motor symptom of Parkinson’s disease. Dual antagonism of adenosine A1 and A2A receptors therefore offers the potential of providing symptomatic relief as well as the neuroprotection so desperately needed in the clinical environment. Amino substituted heterocyclic scaffolds, such as those containing the 2-aminopyrimidine motif, have been shown to exhibit good efficacy as dual adenosine receptor antagonists. Since the structure activity relationships of 2-aminopyrimidines have not been comprehensively explored, it is in this regard that this study aimed to make a contribution. Results - Fourteen 2-aminopyrimidines were synthesised successfully over three steps, (although in low yields) and characterised by nuclear magnetic resonance and infrared spectroscopy, mass spectrometry, by determination of melting points and high performance liquid chromatography. Structure modifications explored included variation of the aromatic substituent on position 4, as well as variations in the substituents of the phenyl ring, present on position 6 of the pyrimidine ring. Radioligand binding assays were performed to determine the affinities of the synthesised compounds for the adenosine A1 and A2A receptor subtypes. Several high dual affinity derivatives were identified during this study; the compound with the highest affinity was 4-(5- methylthiophen-2-yl)-6-[3-(piperidine-1-carbonyl)phenyl]pyrimidin-2-amine (39f) with Ki values of 0.5 nM and 2.3 nM for the adenosine A2A and adenosine A1 receptors, respectively. A few general structure activity relationships were derived, which included: The effect of the aromatic substituent (position 4) on A2A affinity could be summarised (in order of declining affinity) as follows: 5-methylthiophene > phenyl > furan > pyridine > p-fluorophenyl > benzofuran. On the other hand, the effect of this substituent on A1 receptor affinity could be summarised (in order of declining affinity) as follows: phenyl > 5-methylthiophene > pfluorophenyl > benzofuran > pyridine. The affinities as exhibited by the methylthiophene derivatives 39f, 39h – 39j, further showed that while piperidine substitution (39f) resulted in optimal A2A and A1 affinity, pyrrolidine substitution (39j) was less favourable. Substitution at the 4ʹ position of the phenyl ring, as well as thiazole substitution, generally resulted in poor adenosine A1 and A2A receptor affinity. However, 4-[2-amino-6-(5-methylfuran-2-yl)pyrimidin- 4-yl]-N-(1,3-benzothiazol-2-yl)benzamide (39l) surprisingly demonstrated good affinity and selectivity for the adenosine A1 receptor. The results obtained during radioligand binding assays were rationalised by QSAR and molecular modelling (Discovery Studio 3.1, Accelrys) studies. The inverse relationship seen between log Ki (as indicator of affinity) and polar surface area, illustrated the importance of this physico-chemical property in the design of 2-aminopyrimidine A2A antagonists. The results from the docking study further showed that the orientation adopted by derivatives in the binding cavity (and particular hydrogen bonding to Asn 253 and Glu 169) is of importance. Results from the MTT cell viability assay indicated that none of the high affinity derivatives had a significant effect on cell viability at 1 μM, a concentration much higher than their Ki values. However, incorporation of the furan, benzofuran and p-fluorophenyl groups as aromatic substituent and a pyrrolidine as amine substituent, presented liabilities. Lastly, the haloperidol induced catalepsy assay (in rats) was used to give a preliminary indication of adenosine receptor antagonism or agonism. Compound 39f failed to reverse catalepsy under standard conditions, but showed some reversal after an increased time period. Indications therefore exist that 39f is an adenosine receptor antagonist that suffers from bioavailability issues. Compound (39c), 4-phenyl-6-[3-(piperidine-1- carbonyl)phenyl]pyrimidin-2-amine which also demonstrated promising affinity in the radioligand binding assays however showed a statistically significant reduction in catalepsy, indicating adenosine A2A receptor antagonism, and in vivo efficacy. Highly potent, dual affinity aminopyrimidine derivatives with acceptable toxicity profiles were identified in this study, with compound 39c demonstrating in vivo activity. The aim of designing and synthesising a promising dual adenosine A1/A2A receptor antagonist is therefore realised, with compound 39c as the most favourable example. / MSc (Pharmaceutical Chemistry), North-West University, Potchefstroom Campus, 2014

Embodiment in the poetry of Gabeba Baderoon / Elizabeth Louise Nortjé

Nortjé, Elizabeth Louise January 2012 (has links)
This dissertation examines the relation between embodiment and language, knowledge and memory, as explored in the poetry of South African poet Gabeba Baderoon. In her three published collections of poetry, namely, The Museum of Ordinary Life, The Dream in the Next Body and A Hundred Silences, she depicts seemingly trivial and everyday events or experiences with acute attention to detail, all of which are connected by her unique portrayal of their embodied nature. In doing so, her work illustrates that intellectual activities typically associated with the mind, such as language, knowledge and memory, in fact require the incorporation of the body. Therefore, this dissertation studies the mind-body relation represented in her work with regard to these thematic concerns, since it is a crucial aspect of her poetry and aids not only in understanding and interpreting her work, but also the discourse on embodiment in general. These concerns do, moreover, not remain on a thematic level, but are evident in her poetry itself; that is, her poems too act as a form of embodiment. Furthermore, Baderoon’s poems are able to transcend the supposed mind-body dichotomy in a way that shows much in common with phenomenology, and especially the perspective held by authors such as Maurice Merleau-Ponty. This dissertation incorporates phenomenological ideas on the body and embodiment, as these assist in interpreting Baderoon’s work, as well as for the reason that her poetry sheds new light upon the understanding of such phenomenological ideas, too. Thus, this dissertation seeks to elucidate the manner in which Gabeba Baderoon’s poetry transcends the mind-body dichotomy by means of her exceptional employment of the notion of embodiment on a thematic as well as formal level. / Thesis (MA (English))--North-West University, Potchefstroom Campus, 2012

Exploration of mental health workers' coping strategies in dealing with children's trauma / Anna Elizabeth Keyter

Keyter, Anna Elizabeth January 2013 (has links)
Studies of MHWs, (social workers, social auxiliary workers, trauma counsellors, and telephone counsellors), who work with trauma and stress, often focus on pathological symptoms and on the need to develop psycho-education programmes (Figley, 2002; Johnson & Hunter, 1997; Mac Ritchie & Leibowitz, 2010; Mikulincer, 1994; Stiles, 2002). A gap was identified how MHWs, who continuously intervene with traumatised children, cope with the stressors associated with their work. The purpose of this research was to explore the coping strategies of Mental Health Workers (MHWs) exposed to Secondary Trauma (ST)as a result of having to deal day to day with children (younger than 18) who have experienced trauma, including sexual, physical and emotional abuse, as well as the witness of violence. The MHWs’ coping responses were investigated using a qualitative case study approach. The investigation showed how MHWs constructed their realities by examining their coping strategies and the individual meanings they assigned to these. A convenience sample, based on the availability of participants, was selected. Nine women and one man, ranging in age from 26 to 57 years, employed at Childline Gauteng, participated in the research. The Mmogo-Method®, a projective visual research technique, explored the MHWs’ coping experiences through qualitative data collection methods. Visual and textual data were gathered and analysed thematically. It was found that the MHWs at Childline Gauteng displayed two main coping styles, namely intrapersonal and relational coping strategies. In the face of their daily stressors, MHWs managed to cope successfully by using strategies that are embedded in their daily activities. Their ability to find alternative ways to cope, despite continuous exposure to children’s trauma, allowed the MHWs to fulfil their work obligations. Their intrapersonal coping strategies reflected an ability to draw on their inner resources. Being aware of their environment and how it affects them, MHWs were able to regulate themselves and their environments by adopting positive attitudes. These attitudes, and the MHWs’ dispositions, positively affected their outlook on life. Moreover, MHWs maintained a healthy distance from their stressful environment by means of meaningful disengagement. Meaningful disengagement was fundamental to creating solitude as a coping strategy. Personal and professional boundaries, self-care and being able to draw on spirituality were further coping resources. MHWs’ discussions about finding meaning in their work revealed that they would not be able to do their work if they did not experience it as spiritually significant. Drawing on external resources, relational coping strategies included supportive relationships with family, friends and colleagues. Reciprocal unconditional acceptance significantly contributed to coping because it was important for MHWs to experience family and friends' attitudes as supportive and non-judgemental. MHWs encountered an organisational culture of care in the form of freedom to interact with colleagues and managers and sharing experiences. This interaction contributed to successful coping because MHWs felt comfort in the knowledge that they were not alone when dealing with children's trauma. This interaction facilitated coping because MHWs were able to interface successfully with their environment, even in difficult circumstances. In conclusion, the MHWs provided nuanced descriptions of the ways in which they experienced coping strategies. They coped with the demands of their profession by using internal and external resources, including intrapersonal and relational coping. / MA (Research Psychology), North-West University, Potchefstroom Campus, 2014
