1	Faktore wat die dissiplinering van kleuters tydens die egskeidingsproses beїnvloed (Afrikaans) Van Schalkwyk, Ilana 05 November 2007 (has links) This research study focused on the factors that influence the disciplining of pre-school children during the divorce process. Divorce is an escalating phenomenon and more pre-school children are being exposed to divorce. A pre-school child’s development limits his abstract thinking processes which keep him to fully comprehending concepts like divorce. The verbal capacity of pre-school children is still limited and therefore they are not always able to communicate what they experience and observe. They are also not always able to express their emotions. The pre-school child communicates through behaviour and play. Divorce is not only the legal termination of the marriage for adults, but in fact entails more responsibilities, challenges, losses and adaptations. More pressure is placed on the parents and they tend to be emotional overwhelmed, physical exhausted and emotionally drained. This causes that the parents to not see their way open to care for and especially discipline their pre-school child. Discipline in general is left aside and is not followed through consistently. The purpose of this study is of ‘n explorative nature. It aims to explore the factors that have an impact on the disciplining of the pre-school child, prior to, during and after the divorce process. A quantitative research approach has been followed with this study and a questionnaire has been used for gathering information. A non-probability sampling method was used and the respondents were selected through a purposive sample. The respondents were selected from the Pretoria East region. The organisations that assisted the researcher in selecting the respondents were the Counselling centre of the Dutch Reformed Church of Moreletapark and the Child Trauma Clinic. For this study 19 respondents were selected. The questionnaires was given out by hand and collected by hand. The children of the respondents who participated in the study were all pre-school children when going through the divorce. It has been concluded from this study that the factors impacting the discipline of pre-school children during the divorce process, is of an emotional nature. A factor that played an important role in the disciplining of pre-school children is the guilt feelings that the respondents experienced for exposing their children to a divorce. Physical tiredness, emotional exhaustion, conflict between parents during and after the divorce and the number of times that one of the parents leaved the house, are factors that according to the respondents, influenced the disciplining of their pre-school children. / Dissertation (MSD (Play Therapy))--University of Pretoria, 2006. / Social Work and Criminology / MSD / unrestricted Dissipline Ouers Egskeidingsproses Voorskool Ontwikkelingstake Aanpassing Verliese Gesinstake Ouerskapstyle Pre-school child Divorce Discipline Parents Divorce process Pre-school Developmental tasks Kleuter Egskeiding Adjustments Losses Family tasks Parenting styles UCTD
2	An assessment tool for social workers to identify risk behaviour in foster children / Narina Bester Bester, Narina January 2014 (has links) Problem statement Due to HIV and AIDS impacting on communities, devastating consequences have been predicted. The number of orphans and vulnerable children (OVC) in need of care is escalating, causing social workers’ caseloads to become unmanageable. These OVC who lost their parents through death are suffering multiple losses due to being orphaned. The material, protection and affection needs have to be addressed in a holistic, eco-systematic, multidisciplinary team approach. In practice social workers tend to focus mainly on the material and protection needs of OVC due to high caseloads and staff turnover, neglecting their affection needs. Social workers need to work with foster parents and children in identifying potential risk factors that could lead to risk behaviour in foster children who have lost their parents through death. The researcher designed an assessment tool that could enable social workers in practice to do an effective risk assessment of OVC in foster care. Intervention could be planned accordingly by setting goals to address risk factors timeously in an attempt to prevent future problem behaviour in OVC placed in foster care. Aim To develop an assessment tool for social workers to identify risk behaviour in foster children who have experienced multiple losses such as the loss of one or both parents. Method A mixed methods design was used, specifically the sequential and explanatory design which involved collecting and analysing both qualitative and quantitative data. These obtained data were then connected and integrated. Results It was proved that a Risk assessment tool helped social workers to identify risk factors in a team effort between social workers, foster parents and children. Meeting the psychosocial needs of OVC placed in foster care more effectively is important in order to prevent the development of negative behaviour. / PhD (Social Work), North-West University, Potchefstroom Campus, 2015 HIV AIDS Crime Multiple losses OVC Orphans Vulnerable children Child and family care Foster parents Foster children Foster care Social workers Material needs Protection needs Affection needs Risk behaviour Risk factors Assessment tool Emosionele behoeftes MIV VIGS Misdaad Veelvuldige verliese Weeskinders Kwesbare kinders Kindersorg Gesinsorg Pleegouers Pleegkinders Pleegsorg Maatskaplike werkers Materiële behoeftes Beskermingsbehoeftes Riskante gedrag Risikofaktore Assesseringsinstrument

4	Die herskepping van lewensdrome na `n verlies: `n Gestalt perspektief Von Wielligh, Belinda 30 June 2006 (has links) Summaries in English and Afrikaans / Any loss in an adolescent's life may lead to shattered dreams. Therapists, who work with adolescents who have experienced a loss must support and guide them to develop an awareness of their needs, impulses and dreams. Therapists must furthermore be aware of the factors that contributed to a turning point for the adolescents who managed to recreate their dreams. Adolescents' dreams are influenced by the current circumstances in South Africa, as well as their parents' perceptions and parenting styles. The loss of what could have been, after a loss, must also be addressed. The gestalt therapist establishes the process of awareness in the here-and-now. Furthermore, the adolescent must be guided to accept responsibility for his own choices and to purposeful create a new life dream. / Enige verlies in adolessente se lewens kan lei tot verbrokkelde lewensdrome.

5	Modelling the evolution of pulsar wind nebulae / Michael Johannes Vorster Vorster, Michael Johannes January 2014 (has links) This study focusses on modelling important aspects of the evolution of pulsar wind nebulae using two different approaches. The first uses a hydrodynamic model to simulate the morphological evolution of a spherically-symmetric composite supernova remnant that is expanding into a homogeneous interstellar medium. In order to extend this model, a magnetic field is included in a kinematic fashion, implying that the reaction of the fluid on the magnetic field is taken into account, while neglecting any counter-reaction of the field on the fluid. This approach is valid provided that the ratio of electromagnetic to particle energy in the nebula is small, or equivalently, for a large plasma β environment. This model therefore allows one to not only calculate the evolution of the convection velocity but also, for example, the evolution of the average magnetic field. The second part of this study focusses on calculating the evolution of the energy spectra of the particles in the nebula using a number of particle evolution models. The first of these is a spatially independent temporal evolution model, similar to the models that can be found in the literature. While spatially independent models are useful, a large part of this study is devoted to developing spatially dependent models based on the Fokker-Planck transport equation. Two such models are developed, the first being a spherically-symmetric model that includes the processes of convection, diffusion, adiabatic losses, as well as the non-thermal energy loss processes of synchrotron radiation and inverse Compton scattering. As the magnetic field geometry can lead to the additional transport process of drift, the previous model is extended to an axisymmetric geometry, thereby allowing one to also include this process. / PhD (Space Physics), North-West University, Potchefstroom Campus, 2014 Composite supernova remnants Morphological evolution Hydrodynamic Kinematic magnetic field Pulsar wind nebulae Particle evolution models Fokker-Planck transport equation Spherically-symmetric Axisymmetric Diffusion Drift Energy losses Saamgestelde supernova-oorblyfsels Morfologiese evolusie Hidrodinamiese Kinematiese magneetveld Pulsarwindnewels Deeltjie evolusiemodelle Fokker-Planck transport vergelyking Sferies-simmetries Aksiaal-simmetries Diffusie Dryf Energie verliese
6	Modelling of cosmic ray modulation in the heliosphere by stochastic processes / Roelf du Toit Strauss Strauss, Roelf du Toit January 2013 (has links) The transport of cosmic rays in the heliosphere is studied by making use of a newly developed modulation model. This model employes stochastic differential equations to numerically solve the relevant transport equation, making use of this approach’s numerical advantages as well as the opportunity to extract additional information regarding cosmic ray transport and the processes responsible for it. The propagation times and energy losses of galactic electrons and protons are calculated for different drift cycles. It is confirmed that protons and electrons lose the same amount of rigidity when they experience the same transport processes. These particles spend more time in the heliosphere, and also lose more energy, in the drift cycle where they drift towards Earth mainly along the heliospheric current sheet. The propagation times of galactic protons from the heliopause to Earth are calculated for increasing heliospheric tilt angles and it is found that current sheet drift becomes less effective with increasing solar activity. Comparing calculated propagation times of Jovian electrons with observations, the transport parameters are constrained to find that 50% of 6 MeV electrons measured at Earth are of Jovian origin. Charge-sign dependent modulation is modelled by simulating the proton to anti-proton ratio at Earth and comparing the results to recent PAMELA observations. A hybrid cosmic ray modulation model is constructed by coupling the numerical modulation model to the heliospheric environment as simulated by a magneto-hydrodynamic model. Using this model, it is shown that cosmic ray modulation persists beyond the heliopause. The level of modulation in this region is found to exhibit solar cycle related changes and, more importantly, is independent of the magnitude of the individual diffusion coefficients, but is rather determined by the ratio of parallel to perpendicular diffusion. / PhD (Space Physics), North-West University, Potchefstroom Campus, 2013 Cosmic rays Heliosphere Magneto-hydrodynamics Stochastic differential equations Jovian electrons Charge-sign dependent modulation Heliopause Heliospheric current sheet Propagation times Particle drifts Energy losses Kosmiese strale Heliosfeer Magneto-hidrodinamika Stogastiese differentiaalvergelykings Jupiter elektrone Ladingsafhanklike modulasie Heliopouse Heliosferiese neutrale vlak Voortplantingstye Deeltjie dryf Energie verliese
