Co-mentoring: The Iterative Process of Learning about Self and “Becoming” Leaders

Two pre-tenured faculty members at dissimilar institutions found themselves in similar positions – both were assigned to administrative positions that they did not seek. This self-study is an investigation of their processes of becoming leaders and how they aligned and/or conflicted with their espoused beliefs. A review of the literature that guided them is also included. Throughout the process, the two served as co-mentors for each other as they navigated the unfamiliar territory of educational leadership at the university level. Together, they strove to remain committed to shared ideals of democratic practice, transparency, and collaboration. As evidenced in the data, tensions existed as they learned and performed their new roles. Administrative duties and their enactment at times conflicted with their ideals of effective leadership. Electronic journals kept throughout the process were the main data source, which they then revisited to chart their own and each other’s learning and growth while leading. Looking back at their progression, they were able to identify four iterative phases in their development: forming, storming, norming, and performing. Discussions of each phase, with examples, are focal points of the study. The co-mentoring model is one that, while not typically or formally used, was shown to be effective for these two new leaders. Leading each other’s learning helped them align ideals of leading (in teaching and scholarship) with traditional ideas of administration (management tasks and leadership enactments). This study provides clear recommendations for new leaders and those who support them in becoming leaders.

Understanding student evaluations of teaching in online learning

In this paper, we have developed a classification model for online learning environments that relates the Instructors Overall Performance (IOP) rating (according to students’ perceptions) with the course characteristics, students’ demographics and the effectiveness of the instructor in his/her teaching roles. To that end, a comprehensive Student Evaluation of Teaching (SET) instrument is proposed, which includes not only conventional teaching elements, but also items that encourage twenty-first century skills. The goal of the study is twofold: (i) to quantify the extent to which the selected variables explain the IOP rating, and (ii) determine which teaching and non-teaching variables most affect the IOP rating. The best performing classifier achieved a competitive accuracy, highlighting that the selected variables mainly determine the IOP values. Other important findings include: (i) the IOP value is mainly influenced by the effectiveness of the instructor in his/her teaching roles; (ii) teaching strategies that involve the cooperation between the technical and pedagogical roles should be promoted; (iii) the pedagogical role has the highest impact on the final IOP value; and (iv) the most influential demographic variable is the student’s status (working commitments and family responsibilities).     

How to facilitate knowledge diffusion in complex networks: The roles of network structure,knowledge role distribution and selection rule

The diffusion of knowledge within organizations provides opportunities for interpersonal co-operation, improves creative ability and therefore leads to competitive advantage. Focus of prior literature on knowledge diffusion has been on identifying factors that influence individuals' behavioral intentions to seek and share knowledge. However, knowledge diffusion as an enigmatic, emergent and organizational-level process is more than the simple aggregation of individual attributes and needs to be further investigated. Accordingly, this study focuses on three distinct system-level factors, i.e., architectures of connections among individuals, distributions of knowledge roles and designs of selection mechanisms and analyses their effects on knowledge diffusion. To be more specific, we examine three distinct knowledge roles: seekers, contributors and brokers. We also distinguish between three types of selection mechanisms: objective selection mechanisms, feedback-based selection mechanisms and random selection mechanisms. By conducting agent-based simulations on four representative networks, i.e., regular networks, random networks, small-world networks and scale-free networks, our results show that the optimal knowledge diffusion performance can be achieved on scale-free networks where all agents implement objective mechanisms and show characteristics of brokers. Moreover, our results (a) highlight the significance of brokers, (b) illustrate the superiority of objective selection rules and (c) demonstrate that scale-free networks provide an optimal framework for knowledge diffusion. Furthermore, we also find the interdependent relevance of these three factors to knowledge diffusion and propose a qualitative explanation of these findings.     

Fake News

Much has been written about the alleged “crisis” of journalism, with narratives of cultural pessimism centred on the decline of legacy news media, and print media in particular. Whilst factually accurate in parts, such narratives offer an incomplete picture not just of how journalism is declining, but also evolving as it transitions in the digital age. This paper is funded by a major Australian Research Council-study of “Journalism beyond the crisis”, a project which seeks to evaluate the emerging assemblage of journalistic forms, practices, and uses in a transnationally comparative study across four different countries. The present study is a first step in investigating how journalists perceive their roles at a time in which the legitimacy of factual accounts of current events is increasingly put into question. To do so, it draws on in-depth interviews with senior journalists based in London and Sydney, providing topical insights into how these practitioners understand their role in an era of “fake news”. The findings indicate that journalists are particularly concerned about a decrease of public trust in the media, and urge colleagues to adapt more rigorous fact-checking techniques – particularly at times when the role of journalism as a “watchdog” over society appears to be most crucial.     

A National Survey on the Professional Role Conceptions of Journalists in Kenya

The professional role conceptions of journalists have for many years remained a central strand in journalism studies. The present research investigates the professional role conceptions that Kenyan journalists perceive to be the most important in their work. Similarly, the professional role they consider the most important is further analyzed in relation to demographics (age, gender, education, contract type, media type, and media ownership). Findings from a national survey of 504 Kenyan journalists indicate that “providing citizens with information” is the most important role (61.3 percent), followed by “advocate for social change” (51.7 percent). The other major roles include to “support official policies” (46.9 percent), “motivate people to participate in civic activities” (45.6 percent), and “act as watchdog of government” (35.3 percent). The most important role—providing citizens with information—is backed across all demographics with a strong mean of 4.4 on a five-point scale ranging from 1 (“not important at all”) to 5 (“extremely important”). However, the difference of means across all the analyzed demographics are not statistically significant.     

Pushy or a Princess?

Four times as many males as females appeared as experts on flagship television and radio news programmes in the United Kingdom as of the early 2010s. This study draws on four complementary sets of data to explore the reasons behind this disparity. The findings point to a combination of journalists’ news production processes and women’s perceptions of appropriate social norms and roles. A high proportion of woman experts surveyed lack confidence, saying they fear they will be perceived as self-promoting and “pushy” for wanting to appear on air. Broadcast journalists report women need to be persuaded and wooed, acting like “princesses” and therefore making male experts less trouble to recruit.
