Assessing and serving families and communities responsibly: challenges posed in an urban, marginalised setting
C Engelbrecht, M Kasiram
South African Family Practice , 2007,
Abstract: Service provision to families and communities has long been recognised as a complex undertaking involving a multiplicity of role players and systems of care. Systems theory and ecological theory provide useful frameworks for understanding and servicing families and communities, yet there is a clear absence of literature and research on how to converge microsystemic with macrosystemic interventions. Using Rojano\'s1 community family therapy model, which is applicable to South American communities, and Kasiram and Oliphant\'s2 strategies for changing traditional family therapy to suit broader contexts in South Africa, the authors used developmental research within a qualitative framework to develop an indigenous community family therapy model in an urban setting in KwaZulu-Natal, South Africa. The authors utilised nursing students as fieldworkers and service providers in this study. The research process involved several steps: a state-of-the-art review of the family and community, achieved through an assessment of the family and community through community profiling and an epidemiological study of the community; family assessment of families with one child under the age of five years; best practice and model development to intervene at the family and community levels, achieved with the help of community and school meetings and workshops to identify and prioritise needs and problems, followed by bio-psychosocial interventions; refining the model achieved by an evaluation of the interventions through report assessment and on-site assessment and recommending model adjustments based on the evaluation. In designing a community family therapy model, the state-of-the-art review of community needs established several core issues requiring services/interventions. These were problems relating to HIV/AIDS; a lack of knowledge of the immunisation programme in South Africa and of the Road to Health chart; teenage pregnancy and its relationship to risky behaviours, HIV/AIDS, poverty and crime; and a lack of communication within the family. The development of the model involved determining interventions with families and the community, using macrosystemic approaches, such as community meetings and workshops, where priorities were established and joint strategies were planned to address the identified problems. Individual and small-group discussions enriched the understanding of problems/needs, which, combined with macrosystemic approaches such as media coverage and community meetings and workshop/events, worked in synchrony to effectively assess and then service the families and communities. The goal of developing a community family therapy model was achieved. Combining microsystemic and macrosystemic approaches to assess and serve families and communities is particularly helpful in the face of apathy. However, once momentum is achieved in securing a community spirit, it needs to be sustained or else it is lost and may require more effort to reclaim in the future
Electron transparent gold platelets
Jacobus A. A. Engelbrecht,Hendrik C. Snyman
Gold Bulletin , 1983, DOI: 10.1007/BF03214625
Abstract: Fundamental studies using electron microscopy in fields such as alloying and phase growth are facilitated by using thin foils of low instrinsic defect density. Gold foils or platelets produced by precipitation from aqueous solution are particularly suitable.
Die betroubaarheid en faktorstruktuur van die aangepaste meervoudige keuse-formaat van die miner sentence completion scale (MSCS)
A. S. Engelbrecht,L. C. de Jager
South African Journal of Industrial Psychology , 1991, DOI: 10.4102/sajip.v17i2.525
Abstract: The reliability and factor structure of the adapted multiple choice version of the Miner Sentence Completion Scale (MSCS). In this study the multiple choice MSCS was adapted as a result of several criticisms thereof. The internal consistency and factor structure of the adapted MSCS were determined to ascertain the reliability and construct validity of the questionnaire. Results show that the internal consistency is unsatisfactory and that the factor structure is so complex that interpretation becomes virtually impossible. In light of the results of this study and other research findings of the psychometric properties of the MSCS, it is recommended that a new measuring instrument for managerial motivation be developed that will enable a valid testing of the managerial rolemotivation theory. Opsomming Na aanleiding van verskeie punte van kritiek teen die MSCS is die meervoudige keuse-MSCS in hierdie studie aangepas. Ten einde 'n aanduiding van die betroubaarheid en konstrukgeldigheid van die aangepaste MSCS te verkry, is die interne konsekwentheid en faktorstruktuur daarvan bepaal. Die resultate dui daarop dat die interne konsekwentheid onbevredigend en die faktorstruktuur te kompleks vir interpretasie is. In die lig van die bevindinge van hierdie studie, en ander navorsingsbevindinge oor die psigometriese eienskappe van die MSCS, word aanbeveel dat 'n nuwe meetinstrument van bestuursmotivering ontwikkel word wat 'n geldige toetsing van die bestuursrol-motiveringsteorie moontlik sal maak.
Werksbetrokkenheid: 'n Empiriese ondersoek
A. S. Engelbrecht,L. C. De Jager
South African Journal of Industrial Psychology , 1982, DOI: 10.4102/sajip.v0i0.337
Abstract: The relationship between job involvement, job satisfaction and job performance has been investigated. Differences in job involvement between the sexes and between full day and half day female employees were also researched. Two questionnaires and a graphic rating scale were applied to a sample of 164 clerical employees. Job involvement correlated significantly and positively with job performance and also with the different dimensions of job satisfaction. No significant differences regarding job involvement were found between the sexes and between full day and half day female employees. Conclusions are drawn from the results obtained and recommendations are made for future research. Opsomming Aangesien daar 'n komplekse verwantskap tussen werksbetrokkenheid, werkstevredenheid en werksprestasie is en teenstrydige resultate hieroor bestaan, is daar 'n behoefte aan verdere navorsing ten einde hierdie verwantskappe op te klaar. Benewens hierdie verwantskappe is geslagsverskille en moontlike verskille tussen vol- en halfdag vroulike werknemers in werksbetrokkenheid ook ondersoek. Twee vraelyste en 'n grafiese beoordelingskaal is aan 'n monster bestaande uit 164 klerklike personeellede geadministreer. Beduidende positiewe korrelasies is tussen werksbetrokkenheid en werksprestasie en tussen werksbetrokkenheid en die verskillende dimensies van werkstevredenheid gevind. Geen beduidende verskil is tussen mans en vrouens asook tussen vol- en halfdag vroulike werknemers ten opsigte van werksbetrokkenheid verkry nie.
The influence of transformational and transactional leadership on dyadic trust relationships through perceptions of fairness
P. Krafft,A. S. Engelbrecht,C. C. Theron
South African Journal of Industrial Psychology , 2004, DOI: 10.4102/sajip.v30i1.142
Abstract: Leadership and interpersonal trust are critical issues for the survival of organisations. Both aspects have been researched thoroughly, but the role organisational justice might play in this relationship has been largely ignored. The purpose of this study was to investigate the relationship between transformational and transactional leadership and interpersonal trust, and whether organisational justice plays a mediating role. Through LISREL analysis, it was found that interactional justice played a greater role in the relationship between transformational leadership and trust than procedural justice. Distributive justice mediated the relationship between transactional leadership and trust. Opsomming Leierskap en interpersoonlike vertroue is kritieke vraagstukke vir die oorlewing van organisasies. Beide aspekte is reeds deeglik nagevors, maar die rol wat organisatoriese geregtigheid in hierdie verband kan speel, is grootliks nagelaat. Die doel van hierdie studie was om die verband tussen transformasionele en transaksionele leierskap en interpersoonlike vertroue te ondersoek, en of organisatoriese geregtigheid ’n tussenkomende rol speel. Deur middel van LISREL-ontleding is gevind dat interaktiewe geregtigheid ’n groter rol in die verband tussen transformasionele leierskap en vertroue speel as prosedurele geregtigheid. Verdelende geregtigheid dien as tussenkomende veranderlike in die verband tussen transaksionele leierskap en vertroue.

Physics , 2012,
Abstract: We present preliminary results of multi-colour photometry of Beta Cephei stars observed in the LMC and in NGC 6200. Tentative identifications of pulsation modes have been made, and a number of new B pulsators have been noted. Interesting features have also been discovered in the light curves of some of these stars.

Physics , 2009,
Abstract: We have used Lomb-Scargle periodogram analysis and Monte Carlo significance tests to detect periodicities above the 3-sigma level in the Beta Cephei stars V400 Car, V401 Car, V403 Car and V405 Car. These methods produce six previously unreported periodicities in the expected frequency range of excited pulsations: one in V400 Car, three in V401 Car, one in V403 Car and one in V405 Car. One of these six frequencies is significant above the 4-sigma level. We provide statistical significances for all of the periodicities found in these four stars.

On the Relevance of Game Theory in Strategic Thinking
GN Engelbrecht
Scientia Militaria: South African Journal of Military Studies , 1999,
Abstract: The author reviews some of the applicable literature and shows how game theory can be used to predict the outcome of a strategy, explain why a particular outcome to a strategy has occurred, investigate strategy and prescribe certain rules for the making of a strategy. He concludes that game theory can aid decision makers at all levels in formulating quality strategies. In fact, game theory should be an integral and indispensable part of the strategist's toolbox.
