Evaluation of a school‐based transition program designed to facilitate school reentry following a mental health crisis or psychiatric hospitalization

In recent decades, increasing attention has been paid to the number of adolescents experiencing extended absences from school due to mental health crises. Upon returning to school, these students often face difficulties in functioning, risk of relapse, and vulnerability to academic failure and social isolation. This paper presents results of a study examining a school‐based support program model designed to provide short‐term academic, social, and emotional support to help students successfully reacclimatize to school after an extended absence. The paper describes demographic, academic, and clinical characteristics of 189 program participants across eight high schools. Improvements were observed in participants’ day‐to‐day functioning based on the results of pre/postassessments completed by program clinicians. Preliminary data showed positive trends in participants’ school attendance and high school graduation rates. Finally, the paper considers implications for school‐based mental health practice and next steps in related research.     

The broad effectiveness of seventy-four field instances of abstinence-based programming

Evaluations of a large federally funded sexual risk avoidance education (SRAE) efforts in the USA have not been widely reported in the wake of funding cuts. The purpose of this study is to report results from a broad set of programmes to demonstrate the breadth of field effectiveness of these programmes. Twenty-seven separate community-based SRAE programmes were evaluated from 2005 to 2010, comprising 74 separate evaluations and involving over 96,000 young people. Pre- to post-effect sizes on key attitudinal predictors of sexual activity were analysed using meta-analytic techniques, both individually and as an average composite score. The standardised change score effect size on the composite measure were small and statistically significant (d = 0.20, k = 75, p < 0.001), as were effects on individual measures (d = 0.15–0.31). Programmes using a single curriculum showed greater results than those using their own blend of two or more curricula. As a group, this large body of field implementations of SRAE appears to have produced modest but statistically significant effects on key predictors of sexual activity in youth.     

Transformational Leadership: The Nexus Between Faith and Classroom Leadership

Transformational leadership is well documented in organizational and business literature. Classroom and faith-based applications are more recent phenomena. The authors of this mixed-methods study explored professor behaviors and characteristics perceived as transformational in students' faith and focused on transformational leadership in the classroom at a faith-based institution. Thirty-four undergraduate students completed surveys containing open-ended and forced-choice questions; the findings highlighted the importance of compassion, optimism, encouragement, and openness as behaviors that facilitated faith transformation.     

Examining the effectiveness of real-time query expansion

Interactive query expansion (IQE) (c.f. [Efthimiadis, E. N. (1996). Query expansion. Annual Review of Information Systems and Technology, 31, 121–187]) is a potentially useful technique to help searchers formulate improved query statements, and ultimately retrieve better search results. However, IQE is seldom used in operational settings. Two possible explanations for this are that IQE is generally not integrated into searchers’ established information-seeking behaviors (e.g., examining lists of documents), and it may not be offered at a time in the search when it is needed most (i.e., during the initial query formulation). These challenges can be addressed by coupling IQE more closely with familiar search activities, rather than as a separate functionality that searchers must learn. In this article we introduce and evaluate a variant of IQE known as Real-Time Query Expansion (RTQE). As a searcher enters their query in a text box at the interface, RTQE provides a list of suggested additional query terms, in effect offering query expansion options while the query is formulated. To investigate how the technique is used – and when it may be useful – we conducted a user study comparing three search interfaces: a baseline interface with no query expansion support; an interface that provides expansion options during query entry, and a third interface that provides options after queries have been submitted to a search system. The results show that offering RTQE leads to better quality initial queries, more engagement in the search, and an increase in the uptake of query expansion. However, the results also imply that care must be taken when implementing RTQE interactively. Our findings have broad implications for how IQE should be offered, and form part of our research on the development of techniques to support the increased use of query expansion.     

Information systems management: The need for a post-modern approach

This paper proposes a post-modern way of thinking about the development and the management of information systems and especially information systems development. The paper proposes a framework for a co-evolutionary or co-creation approach to information systems development and management incorporating all the main stakeholders.     

The Leaking Pipeline: Women Postgraduate and Early Career Researchers in Australia

This paper explores the leaking pipeline in women's participation rates from Bachelor to postgraduate research programmes. In examining projects at two Australian universities to identify and implement strategies to improve women's participation in research higher degrees, it focuses on three points of leakagebetween Bachelor and Bachelor with Honours degree programmes, Bachelor degree with Honours and postgraduate research programmes, and completion of postgraduate research and taking up a postdoctoral position, and the links between them. It examines three important consequences of women not undertaking or completing postgraduate research: entering academia at lower levels or in casual positions, often while doing postgraduate research part-time; tending to focus on teaching rather than research; and, due to under-representation at middle levels, not achieving a critical mass in senior academia. The paper suggests ways in which university policy may impact on women's participation in postgraduate research programmes through implementation of university-wide and departmental policies encompassing the strategies identified in these studies.
