Group processes and dynamics in relation to transactional and transformational leadership

This study investigated the relationship between leadership style and group processes and dynamics with due consideration of the role of related systems in the context of organisational change. The theoretical assumptions and practical implications of the full range model of leadership were discussed. This model emphasises the transactional-transformational paradigm. In addition, approaches to studying and working with groups were covered, focusing specifically on group processes and group dynamics. In the case of the latter, the systems psychodynamic perspective was emphasised. The present study was conducted in a plant of a South African production organisation that had been experiencing transformation. An intervention was done at management level to identify behavioural and operational issues and to sensitise the members of the management team in terms of individual and group functioning. The conceptualisation of leadership styles in terms of the full range model of leadership was largely supported by means of associations with certain personality traits and behaviours. The latter also provided a profile of desired characteristics, especially in terms of interpersonal styles and work and social ethics. The theory on group processes and dynamics was used to explore group and organisational functioning. The context of change and the related insecurity resulted in efforts to deal with anxiety by means of excessive reliance on structure. Centralised leadership and a dynamic of control and dependency characterised all levels of the organisation. Cooperation in an interdependent manner was therefore problematic and there was also a struggle in terms of interrelatedness in and between systems. The unconscious defence strategy was related to the general reliance on transactional behaviours and the lack of authorisation of leadership in terms of transformational behaviours. Despite the successful application of theory in the present study and the contribution made by the results, it was concluded that the uniqueness and the realities of each situation need to be explored and provided for, and a system should be allowed to determine the progression in the system.PsychologyD.

Exploring the learnings derived from catalytic experiences in a leadership context

Orientation: Personal leadership comprises self-awareness, authenticity, inspiration and passion. The concept of personal leadership was explored together with its relationship with leadership-related learnings derived from a catalytic experience. Research purpose: The objective of the study was to explore the leadership-related learnings derived from a catalytic experience and any connection between these learnings, personal leadership and leadership in an organisational context. Motivation for the study: Measurement of leaders’ performance remains largely focused on the results achieved. The importance of personal leadership in the corporate environment is often ignored and even questioned. Recognising that there is a relationship between personal leadership and professional leadership enables leaders to connect who they are being and what they are doing. This can enhance their leadership. Research design, approach and method: The study was conducted using a qualitative approach, specifically narrative enquiry. The sample comprised seven leaders who have had catalytic experiences in their lives. In-depth interviews were conducted and thematic analysis was used to identify themes on the leadership-related learnings gained from the leaders’catalytic experiences. Main findings: Elements of personal leadership and the processes involved in the development of personal leadership were identified. It was furthermore shown that challenging experiences serve as learning opportunities and that time for reflection is essential in this learning process. Practical/managerial implications: Leadership lessons are best learnt through experience.Using challenging experiences as learning opportunities may assist leaders in their growth and development. Contribution: Leadership effectiveness and organisational effectiveness may be enhanced by a more holistic view of leadership that includes elements of personal leadership

<img src="http://openjournals.net/files/pics/CEU.gif"/> Exploring the development of an organisational culture of control and dependency from a systems psychodynamic perspective

Orientation: Globalisation and accelerating rates of change characterise the work environment. Research purpose: The aim of this research was to study the impact of the change process at a plant of a South African production company. Motivations for the study: Problems were experienced in terms of production and a need for transformation at different levels was expressed. Co-dependence in the environment necessitated exploration of intra-organisational dynamics. Research design, approach and method: The study focused on the management team at a specifc plant, but by applying the systems psychodynamic perspective it was possible to also explore the mutual effect of relationships with other systems in the organisation, the company as a whole and the environment. Respondents included the directors of manufacturing and of human resources, the general manager, an 11-member management team and staff representatives. Semi-structured one-to-one interviews, group interviews and a group consultation session were held. Main findings: Hypotheses were formulated regarding the change experienced in the company, the overemphasis of control in the various systems, efforts to move from dependency to interdependence, personal authority as a requirement for interdependent functioning and problems with interrelatedness. Practical/managerial implications: The study illustrates the application of the systems psychodynamic approach in exploring the interaction between and mutual infuence of various organisational systems, especially in times of change. Contribution/value add: At a broader level, the study contributes to the understanding of the application of the theory as well as suggesting the use of a methodology. Recommendations for an intervention of this nature were also made

The cognitive processing potential of infants: Exploring the impact of an early childhood development programme

Background: Many South African learners seem unprepared for formal education, and a need for intervention during early childhood has been identified. Aim: The present study explored the effect of infant exposure to an early childhood development programme aimed at the sensory developmental stage of the infant’s brain. Setting: Participants were recruited through local baby clinics and nursery schools in the Western Cape. Participants were from the middle-income sector and the sample consisted of 63 infants between the ages of 3 and 12 months – gender representation was approximately equal and 17% of the infants were of mixed race, 8% black and 75% white. Methods: A pretest–posttest design was used involving an intervention group (N = 29) and a control group (N = 34) of infants. There was no known bias in group allocation. Intervention was provided in the form of the Numbers in Nappies programme and cognitive performance was assessed with the BSID (III) before and after the intervention for both groups. Results: The intervention group showed theory expectant increases, most notably on the Cognitive Scale and the Social-Emotional Scale of the BSID (III). The performance of the intervention and the control group on the cognitive subscales (Cognitive, Language and Motor) was compared before and after the intervention. The only significant difference was on the Cognitive Scale after the intervention. Conclusion: The findings indicate that appropriate intervention taps into the cognitive processing potential of infants, thus increasing their cognitive ability and enhancing their social–emotional functioning. The stimulation provided by parents and primary caregivers is essential in enhancing this experience-dependent development and the Numbers in Nappies programme provides a cost-effective intervention suitable for a home environment

The relevance of the psychometrist category as a professional resource: Training-related issues

Orientation: The professional status of psychometrists places them in a position where they can provide a specialist function independently and their services should therefore be relevant to a variety of settings. Research purpose: The aim was to explore if the training of student psychometrists contributes to the relevance of this category in terms of the demographic profile of student psychometrists, the scope of services potentially provided by them and the content of training programmes. Motivation for the study: There is a paucity of research on training in the psychometrist category. Research design, approach and method: Data were obtained from the files of a cohort of student psychometrists who were registered in the Department of Psychology at the University of South Africa (UNISA). Follow-up surveys on training and work contexts were conducted amongst these students and their in-practice supervisors to confirm and supplement the data. In addition, a survey on the national availability of training programmes for psychometrists was conducted at South African universities. Main findings: Gender and racial skewness in terms of the demographic profile of the UNISA students seemed to reflect a national trend. In terms of the scope of services, training opportunities and perceived job opportunities for psychometrists seemed limited and despite the utilisation of the skills area in all the applied contexts, concerns related to the sectors being served were identified. With regard to the content of the training programmes, students and in-practice supervisors expressed a need for greater preparation in test use before related practical experience takes place. The importance of the university’s involvement during the practicum was also emphasised. Practical/managerial implications: Recommendations are made regarding the structure and content of training programmes. This information could be applied in adapting existing programmes and in developing new programmes. Contribution/value-add: Ultimately, these recommendations could contribute to the value of the psychometrist category as a professional resource relevant to a variety of settings

Care on demand in nursing homes : a queueing theoretic approach

Nursing homes face ever-tightening healthcare budgets and are searching for ways to increase the efficiency of their healthcare processes without losing sight of the needs of their residents. Optimizing the allocation of care workers plays a key role in this search as care workers are responsible for the daily care of the residents and account for a significant proportion of the total labor expenses. In practice, the lack of reliable data makes it difficult for nurs ing home managers to make informed staffing decisions. The focus of this study lies on the ‘care on demand’ process in a Belgian nursing home. Based on the analysis of real-life ‘call button’ data, a queueing model is presented which can be used by nursing home managers to determine the num ber of care workers required to meet a specific service level. Based on numerical experiments an 80/10 service level is proposed for this nursing home, meaning that at least 80 percent of the clients should receive care within 10 minutes after a call button request. To the best of our knowledge, this is the first attempt to develop a quantitative model for the ‘care on demand’ process in a nursing home

Zebrafish embryos as a model host for the real time analysis of Salmonella typhimurium infections

Bacterial virulence is best studied in animal models. However, the lack of possibilities for real time analysis and the need for laborious and invasive sample analysis limit the use of experimental animals. In the present study 28 h-old zebrafish embryos were infected with DsRed-labelled cells of Salmonella typhimurium. Using multidimensional digital imaging microscopy we were able to determine the exact location and fate of these bacterial pathogens in a living vertebrate host during three days. A low dose of wild-type S. typhimurium resulted in a lethal infection with bacteria residing and multiplying both in macrophage-like cells and at the epithelium of blood vessels. Lipopolysaccharide (LPS) mutants of S. typhimurium, known to be attenuated in the murine model, proved to be non-pathogenic in the zebrafish embryos and were partially lysed in the bloodstream or degraded in macrophage-like cells. However, injection of LPS mutants in the yolk of the embryo resulted in uncontrolled bacterial proliferation. Heat-killed, wild-type bacteria were completely lysed extracellularly within minutes after injection, which shows that the blood of these zebrafish embryos does already contain lytic activity. In conclusion, the zebrafish embryo model allows for rapid, non-invasive and real time analysis of bacterial infections in a vertebrate hos
