Agency and Structure: Principals’ Ability to Bring about Sustainable Improvement in Underperforming Schools in South Africa

This article reports on a study of which the purpose was to understand the role of principals in changing underperforming schools towards sustainable improvement in one circuit area of North-West, South Africa. School principals play a crucial role in guiding schools towards sustainable improvement by shaping a vision of academic success for all learners. Managing teaching is one of the core modules in South Africa’s new national qualification for school principals, and that being the case, principals should play a central role in effecting the educational transformation of all learners. The quality of principals’ leadership is the key factor driving the transformational turnaround and improvement required in schools. They perform a highly complex and dynamic role in enhancing and sustaining school improvement. It was the goal of this qualitative study to explore cultural, structural, and agential challenges faced by principals in their effort to provide for change and improvement in their schools. Six schools were purposefully selected to participate in the study and semi-structured interviews were used to gather data from the principals. The study established that paying attention to cultural, structural and agential factors in schools increases their ability to sustain learner improvement.

Coaches as sport workers: professional agency within the employment context of elite European basketball

Increased activity of multiple stakeholders (e.g. agents and owners) have created new challenges for some coaches working in professional sports clubs. The purpose of this project was to draw attention to the normative or accepted practices inherent in sport work, some of the day-to-day realities of some coaches working in this context, and to understand how coaches’ perceptions of other stakeholders come to bear on their individual circumstances, career expectations/objectives and professional agency. Data were generated from semi-structured interviews with seven professional basketball coaches who worked in top-level European clubs. The analysis reveals the coach’s relationships between some owners and agents differed with respect to exercising professional agency, and, coach’s decisions and actions were tied to their professional ideals as well as understandings of what they need to undertake their work effectively and negotiation and/or adjustment strategies. Occasionally coach’s work practices could be viewed as antithetical to employment security, however, the presence of insecurity was at times embraced and used strategically to affect workers’ career decisions. Amid contemporary regional geo-political shifts, this work aids examinations of global sport settings, structures and issues that may contour sporting professionals’ lives.

认证机构服务质量对关系质量影响实证研究

摘要：本文在认证行业领域,研究了认证机构服务质量对关系质量的影响。在认证机构服务质量4维度结构（即过程服务能力、过程交互质量、潜在服务能力和结果质量）及关系质量3维度结构（即合作性、适应性和关系氛围）的基础上,构建了认证机构服务质量对关系质量的影响模型。对721家企业的实证研究表明,过程服务能力、结果质量两个维度对认证机构和顾客之间的关系质量有显著影响,而过程交互质量、潜在服务能力两个维度对两者关系质量的影响不显著。最后对认证机构如何提高其服务质量,维持良好的顾客关系提出了建议。
