An Expanded Model of Distributed Leadership in Organizational Knowledge Creation

Based on a three-year qualitative, longitudinal case study of a social venture partnership, we extend the understanding of distributed leadership in organizational knowledge creation. We develop an expanded model of distributed leadership that identifies the antecedents, different forms, and enablers of distributed leadership in knowledge creation. Our findings move beyond a static and monolithic understanding of distributed leadership to illustrate how an expanded model informs the situational leadership framework and spiral of knowledge creation across an organization's hierarchy and boundary in the context of social entrepreneurship

On the statistical evaluation of dose-response functions

The linear-quadratic dependence of effect on the dose of ionizing radiation and its biophysical implications are considered. The estimation of the parameters of the response function and the derivation of the joint confidence region of the estimates are described. The method is applied to the induction of pink mutations inTradescantia which follows the linear-quadratic model. The statistical procedure is also suitable for other response functions

Orchardgrass Pastures for Early-Weaned Beef Calves

Orchardgrass (Dactylis glomerata) grown alone or with ladino white (Trifolium repens) and red (T. pratense) clovers, provides a high quality March to June pasture. However, many beef producers have their cows calving in January-March, thus producing offspring that are too young to utilize spring forage well. As an alternative, some producers have their cows bred so that calves are born in autumn (September-November). By spring, these calves are old enough to consume pasture forage. The few earlier studies on early weaning of fall-born calves consist of drylot feeding of high quality hay or concentrates. This study evaluated the potential of orchardgrass and orchardgrass clover pastures to meet the nutritional needs of early-weaned fall-born beef calves (Bos taurus). Fallborn steers, 4.5-mo old, weighing about 144 kg, were used in each of 3 yr. Twenty-four were weaned and allotted at random to one of four duplicate pasture treatments: (1) TN-Syn-2 orchardgrass, grown alone or (2) with ladino white and red clovers ; (3) ‘Benchmark’ orchardgrass, grown alone or (4) with the clovers; another 24 remained with their dams. Early-weaned calves on high quality pastures performed well, with daily gains between 640 and 925 g d-1. Dams which were not suckled were in better body condition going into the summer than those with calves

Relação treinador-atleta e exercício da liderança no desporto: a percepção de treinadores de alta competição

Neste artigo apresentamos os resultados de quatro entrevistas levadas a cabo com treinadores de alta competição portugueses, onde se procurou recolher informações sobre as competências necessárias para exercer a actividade de treinador, os princípios e filosofia adoptada no trabalho, as principais áreas de exercício da liderança e os valores defendidos na modalidade e na prática profissional. Os resultados permitiram verificar um acordo quanto à importância de possuírem boas competências conceptuais e pessoais, princípios claros e aceites pelos atletas, boas condições de trabalho e atletas com qualidade para a alta competição. Paralelamente, foi evidente a complexidade de tarefas assumidas na orientação dos atletas (nove dimensões do exercício da liderança). Por último, é de salientar a importância dada à obtenção dos resultados competitivos (objectivo principal) em conjunto com a análise satisfatória do trabalho realizado e a valorização do desenvolvimento pessoal, tanto no treinador como nos atletas (objectivos “periféricos”).Coach-athlete relationship and leadership practice: the perceptions of four high level competition coaches. On this article we present the results on interviewing four high level competition Portuguese coaches. The aim was to look for information on the essential coaching competences, the working principles and philosophy, the main leadership exercise areas and the defended values on sports and professional practice. The results showed the relevancy of gathering good conceptual and personal competencies, clear and accepted principals, good working conditions and qualified athletes. Also evident were the complex tasks assumed on guiding the athletes (nine leadership exercise dimensions were found). Finally, it is essential to point out the importance given to obtaining sporting results (main goal) as well as the satisfactory working analyses and the value given to coaches’ and athletes’ self-development (side goals).(undefined

Individual leader to interdependent leadership: A case study in leadership development and tripartite evaluation

This article is available open access through the publisher’s website at the link below. Copyright @ 2013 Sage Publications.The Problem - In this case study we see a move away from orthodox views of school leadership as “headship” to a more contemporary model of educational leadership wherein we note a departure from functional, curricula-based school leadership toward more human resource development (HRD) approaches. The aim of this study was to consider the effectiveness of an educational development program for middle leaders within an educational establishment. The Solution - We examined the impact of a bespoke higher education leadership development intervention in Leadership (and Change) on the formation and cohesiveness of a newly formed innovative leadership structure. The Stakeholders - The leadership development intervention was designed through a tripartite collaboration including a university, senior school leaders, and staff. The intervention was designed to shift leadership from individual leader agency to interdependent human leadership agency. Through tripartite evaluation we uncover leadership development praxis that transcends the boundaries of conventional educational leadership and reemphasizes the benefits of bridging the academic/practitioner divide and the application of theory to praxis

The influence of distributed leadership on teachers' organizational commitment: a multilevel approach

In the present study the effects of a cooperative leadership team, distributed leadership, participative decision-making, and context variables on teachers' organizational commitment are investigated. Multilevel analyses on data from 1522 teachers indicated that 9% of the variance in teachers' organizational commitment is attributable to differences between schools. The analyses revealed that especially the presence of a cooperative leadership team and the amount of leadership support played a significantly positive key role in predicting teachers' organizational commitment. Also, participative decision-making and distribution of the supportive leadership function had a significant positive impact on teachers' organizational commitment. In contrast, distribution of the supervisory leadership function and teachers' job experience had a significant negative impact

Governance tools for board members : adapting strategy maps and balanced scorecards for directorial action

The accountability of members of the board of directors of publicly traded companies has increased over years. Corresponding to these developments, there has been an inadequate advancement of tools and frameworks to help directorial functioning. This paper provides an argument for design of the Balanced Scorecard and Strategy Maps made available to the directors as a means of influencing, monitoring, controlling and assisting managerial action. This paper examines how the Balanced Scorecard and Strategy Maps could be modified and used for this purpose. The paper suggests incorporating Balanced Scorecards in the Internal Process perspective, ‘internal’ implying here not just ‘internal to the firm’, but also ‘internal to the inter-organizational system’. We recommend that other such factors be introduced separately under a new ‘perspective’ depending upon what the board wants to emphasize without creating any unwieldy proliferation of measures. Tracking the Strategy Map over time by the board of directors is a way for the board to take responsibility for the firm’s performance. The paper makes a distinction between action variables and monitoring variables. Monitoring variables are further divided on the basis of two considerations: a) whether results have been met or not and b) whether causative factors have met the expected levels of performance or not. Based on directorial responsibilities and accountability, we take another look at how the variables could be specified more completely and accurately with directorial recommendations for executives

Judging the impact of leadership-development activities on school practice

The nature and effectiveness of professional-development activities should be judged in a way that takes account of both the achievement of intended outcomes and the unintended consequences that may result. Our research project set out to create a robust approach that school staff members could use to assess the impact of professional-development programs on leadership and management practice without being constrained in this judgment by the stated aims of the program. In the process, we identified a number of factors and requirements relevant to a wider audience than that concerned with the development of leadership and management in England. Such an assessment has to rest upon a clear understanding of educational leadership,a clearly articulated model of practice, and a clear model of potential forms of impact. Such foundations, suitably adapted to the subject being addressed, are appropriate for assessing all teacher professional development
