Exploring the effects of a coaching leadership style on the relationships between managers and direct reports in South Africa

A research report submitted to the faculty of Commerce, Law and Management, University of the Witwatersrand, in partial fulfilment of the requirements for the degree of Master of Management (Business and Executive Coaching) Johannesburg, 2017The objective of the study was to explore how a coaching leadership style adopted by Managers in different organisations, influences the relationships they have with their direct reports. The study used the qualitative method and semi-structured interviews were conducted with 22 participants, comprising 13 Managers and nine Direct Reports in various organisations in private and public sectors based in Gauteng, South Africa. This study contributes to the research and literature available on coaching leadership style and employee coaching, which occurs when an employee works one-on-one with his/her direct manager to improve his/her work performance and other areas that need attention. Executive Coaching has been extensively researched and refers to when an executive in an organisation is being coached by an external coach who is normally chosen by the Executive and paid for by the organisation. In Employee Coaching however, the coaching is conducted by the direct Manager and the employee has no choice in who the Manager is. Relationships between Manager and Direct Report are therefore crucial and these could be influenced by the Manager‟s leadership style. The findings suggest that within a South African context, the term “Coaching Leadership Style” is not a term that is widely used in organisations to describe a leadership style, however this style emerged through the behaviours that the Managers displayed. The findings further posit that coaching plays a pivotal role in influencing relationships between a Manager and his/her Direct Reports and that coaching may also cause shifts in leadership styles. The research provides insight into the leadership styles that Managers prefer to adopt and deepened understanding of how coaching adds value in a leadership context. The results add to the body of knowledge on how coaching affects leadership effectiveness and how it influences relationships between Managers and Direct Reports.MT201

The Dimerization of an α/β-Knotted Protein Is Essential for Structure and Function

Summaryα/β-Knotted proteins are an extraordinary example of biological self-assembly; they contain a deep topological trefoil knot formed by the backbone polypeptide chain. Evidence suggests that all are dimeric and function as methyltransferases, and the deep knot forms part of the active site. We investigated the significance of the dimeric structure of the α/β-knot protein, YibK, from Haemophilus influenzae by the design and engineering of monomeric versions of the protein, followed by examination of their structural, functional, stability, and kinetic folding properties. Monomeric forms of YibK display similar characteristics to an intermediate species populated during the formation of the wild-type dimer. However, a notable loss in structure involving disruption to the active site, rendering it incapable of cofactor binding, is observed in monomeric YibK. Thus, dimerization is vital for preservation of the native structure and, therefore, activity of the protein

Enabling the transfer of skills and knowledge across classroom and work contexts

Increasingly, contemporary work means graduates will operate in multiple workplace settings during their careers, catalysing the need for successful transfer of capabilities across diverse contexts. The transfer of skills and knowledge, however, is a complex area of learning theory which is often assumed and lacks empirical analysis. Facilitating transfer is critical for preparing students for effective transition to the workplace. Work Integrated Learning (WIL) provides an opportunity for tertiary education students to ‘practice’ transfer across classroom and work settings. Building on existing scholarship and using a mixed-methods design, this study aimed to explore the nature of transfer across these contexts during WIL, influencing factors and WIL design principles that optimise transfer. Survey data were collected from WIL students (N = 151) and interview data from WIL industry supervisors (N = 24) across different disciplines/professions in three universities (Australia and New Zealand). Findings indicate that students practice transfer during WIL, yet it is often during less complex tasks that relate to discipline-specific skills, rather than generic ones. WIL thus augments transfer, yet certain program and workplace characteristics enhance student confidence and capabilities in this process, highlighting the need for careful curricula design. Findings also highlighted the important role of paid work and volunteering and emphasise the importance of educators taking a holistic approach to developing students’ transfer ability, drawing on practical and authentic learning in curricular, co-curricular and extra-curricular activities, particularly those that engage industry. Implications for stakeholders are discussed, and strategies identified to enhance skills and knowledge transfer from classrooms to the workplace

Transnuclear CD8 T cells specific for the immunodominant epitope Gra6 lower acute-phase Toxoplasma gondii burden.

We generated a CD8 T-cell receptor (TCR) transnuclear (TN) mouse specific to the Ld -restricted immunodominant epitope of GRA6 from Toxoplasma gondii as a source of cells to facilitate further investigation into the CD8 T-cell-mediated response against this pathogen. The TN T cells bound Ld -Gra6 tetramer and proliferated upon unspecific and peptide-specific stimulation. The TCR beta sequence of the Gra6-specific TN CD8 T cells is identical in its V- and J-region to the TCR-β harboured by a hybridoma line generated in response to Gra6 peptide. Adoptively transferred Gra6 TN CD8 T cells proliferated upon Toxoplasma infection in vivo and exhibited an activated phenotype similar to host CD8 T cells specific to Gra6. The brain of Toxoplasma-infected mice carried Gra6 TN cells already at day 8 post-infection. Both Gra6 TN mice as well as adoptively transferred Gra6 TN cells were able to significantly reduce the parasite burden in the acute phase of Toxoplasma infection. Overall, the Gra6 TN mouse represents a functional tool to study the protective and immunodominant specific CD8 T-cell response to Toxoplasma in both the acute and the chronic phases of infection

Distribution of ions near a charged selective surface in critical binary solvents

Near-critical binary mixtures containing ionic solutes near a charged wall preferentially adsorbing one component of the solvent are studied. Within the Landau-Ginzburg approach extended to include electrostatic interactions and the chemical preference of ions for one component of the solvent, we obtain a simple form for the leading-order correction to the Debye-Huckel theory result for the charge density profile. Our result shows that critical adsorption influences significantly distribution of ions near the wall. This effect may have important implications for the screening of electrostatic interactions between charged surfaces immersed in binary near-critical solvents.Comment: 24 pages, 3 figure

An Experimental Course: Animal Handling, Safety, and Well-Being

Students in the Department of Animal Science at Iowa State University are coming from increasingly diverse backgrounds, with little to no experience working with or handling various livestock species. In order to best accommodate these students, additional courses are being developed, one of which is Animal Science 190X: Animal Handling, Safety, and Well-Being. Through the course, students handle all major livestock species; sheep, swine, poultry, horses, beef cattle and dairy cattle, and are required to demonstrate handling knowledge and skills learned as part of a final assessment. This creates an opportunity for students lacking a livestock background to feel more confident and safer as they interact with livestock species both throughout their collegiate careers and as they enter into the animal agriculture industry

Testing together challenges the relationship': Consequences of HIV Testing as a couple in a High HIV prevalence setting in Rural South Africa

OBJECTIVE: We conducted qualitative individual and combined interviews with couples to explore their experiences since the time of taking an HIV test and receiving the test result together, as part of a home-based HIV counselling and testing intervention. METHODS: This study was conducted in October 2011 in rural KwaZulu-Natal, South Africa, about 2 years after couples tested and received results together. Fourteen couples were purposively sampled: discordant, concordant negative and concordant positive couples. FINDINGS: Learning about each other’s status together challenged relationships of the couples in different ways depending on HIV status and gender. The mutual information confirmed suspected infidelity that had not been discussed before. Negative women in discordant partnerships remained with their positive partner due to social pressure and struggled to maintain their HIV negative status. Most of the couple relationships were characterized by silence and mistrust. Knowledge of sero-status also led to loss of sexual intimacy in some couples especially the discordant. For most men in concordant negative couples, knowledge of status was an awakening of the importance of fidelity and an opportunity for behaviour change, while for concordant positive and discordant couples, it was seen as proof of infidelity. Although positive HIV status was perceived as confirmation of infidelity, couples continued their relationship and offered some support for each other, living and managing life together. Sexual life in these couples was characterized by conflict and sometimes violence. In the concordant negative couples, trust was enhanced and behaviour change was promised. CONCLUSIONS: Findings suggest that testing together as couples challenged relationships in both negative and positive ways. Further, knowledge of HIV status indicated potential to influence behaviour change especially among concordant negatives. In the discordant and concordant positive couples, traditional gender roles exposed women’s vulnerability and their lack of decision-making power.Department of HE and Training approved lis

I am working with three others on the suspension and steering sybsystems for the Zips Electric Racing design team at The University of Akron. We are improving upon last year\u27s design to help create an optimized vehicle. As part of this project, we take part in weekly design reviews and team meetings, model parts in Solidworks, and perform simulations and FEA using MATLAB/SIMULINK, Solidworks, and Optimum Kinematics

Educators Voices from Integrated Writing and Problem Solving Common Core Workshop

This article provides an opportunity to discuss and examine information gathered during a focus group of K-12 educators involved in an integrated writing and problem solving workshop. Findings demonstrate that some educators are frustrated by the culture of testing versus the culture of learning that exist as a result of the Common Core Standards implementation. Educators are eager to learn and implement new ways of learning in order to promote deeper learning and critical thinking skills. Strategies and recommendations for providing support and resources for educators to meet the expectations to prepare students to be college and career ready are discussed
