During early to mid adolescence,moderate to vigorous physical activity is associated with restoring sleep,psychological functioning,mental toughness and male gender

Numerous studies showed that regular physical activity (PA) is associated with both favourable and restorative sleep and improved psychological functioning (PF). However, there is little research on the topic covering the early to mid-adolescence period. Moreover, curiosity and exploratory behaviour (CEB) and mental toughness (MT) as a result of PA remains thus far uninvestigated, as do possible gender differences. The aim of the present study was to explore the associations between PA, subjective sleep (sS), PF, CEB, and MT during early to mid-adolescence. A total of 1361 participants (mean age = 13.37 years; range: 11–16 years; 51.2% female) took part in the study. They completed questionnaires covering PA, sS, PF, CEB, and MT. Greater PA was related to improved PF, better sS, and increased CEB and MT. Compared to male participants, females reported less PA, poorer sS, and had lower PF and MT scores. The present pattern of results suggests that during early and mid-adolescence greater PA was associated with more favourable sS and better PF, including CEB and MT, and that female participants reported lower scores in PA, sS, and PF. Accordingly, if PA has a favourable impact on sleep and psychological functioning, then data suggest that sports participation should be more tailored to increase motivation among female adolescents.     

Interdisciplinary and transdisciplinary research and practice: Balancing expectations of the ‘old’ academy with the future model of universities as ‘problem solvers’

Academics are increasingly required to balance the expectations of the ‘old’ academy with a future model of universities as interdisciplinary and transdisciplinary ‘problem solvers’. This paper highlights changing expectations of academics in producing alternative research outcomes in collaborative, practice‐based research. Through a series of workshops with 20 researchers, preferred research outcomes and tensions in achieving these outcomes were identified. The tensions identified are presented as three dichotomies comprising the tension between: (a) ‘I versus We’ ‐ individual versus team expectations & outcomes. (b) Disciplinary outcomes versus inter‐/transdisciplinary outcomes. (c) Learning versus research objectives for the students and academics involved. These tensions reflect the authors' experiences of working in three international sustainability projects, drawing on lessons learned from these projects, with recommendations for universities seeking to implement interdisciplinary and transdisciplinary doctoral and postdoctoral programmes. Recommendations include the need for formal and informal leadership models, strong communication skills, empathy and willingness to learn from each other. A need for more systemic changes within university administration to better reward and value the breadth and depth of collaborative work, while facilitating open learning cultures and practice‐oriented learning opportunities and curricula across faculties was also identified.     

Performance of the geometric approach to fault detection and isolation in SISO, MISO, SIMO and MIMO systems

In this paper,a geometric approach to fault detection and isolation (FDI) is applied to a Multiple-Input Multi-ple-Output (MIMO) model of a frame and the FDI results are compared to the ones obtained in the Single-Input Single-Output (SISO),Multiple-Input Single-Output (MISO),and Single-Input Multiple-Output (SIMO) cases. A proper distance function based on parameters obtained from parametric system identification method is used in the geometric approach. ARX (Auto Regressive with eXogenous input) and VARX (Vector ARX) models with 12 parameters are used in all of the above-mentioned models. The obtained results reveal that by increasing the number of inputs,the classification errors reduce,even in the case of applying only one of the inputs in the computations. Furthermore,increasing the number of measured outputs in the FDI scheme results in decreasing classification errors. Also,it is shown that by using probabilistic space in the distance function,fault diagnosis scheme has better performance in comparison with the deterministic one.     

Attracting Students to the Field of Measurement

To address the shortage of professionals in measurement, it is essential that we make young career‐seekers aware that measurement is an option as a profession. In this paper, we discuss how creating a strong pipeline of students into our field involves personal interactions between faculty representing the graduate programs in measurement and undergraduate students, in addition to the equally important task of educating instructors of undergraduates about our field. We describe advertising strategies that, in our experience, catch and hold the attention of undergraduates, resulting in many of them investigating graduate training in measurement. After attracting students to the field, we must engage them in practice, enabling them to build an identity as a measurement professional. In general, we believe that although it is possible to attract some students via non‐personal advertising strategies (e.g., articles, websites), measurement professionals must personally reach out to young people to connect them with the field.     

TEACHING RESEARCH IN GERONTOLOGY: TOWARD A CUMULATIVE MODEL

In this article, we consider different approaches to teaching research methods in gerontology across a continuum of educational program levels. Our goal is to offer a conceptual framework and stimulate productive discussion of key issues and challenges in teaching research in gerontology. It is our belief that education in gerontology should include some level of training in research methodologies across all levels of gerontology instruction. Therefore, we have sought to identify those components of research training most appropriate for each level of gerontological education. Thus, basic understanding of research methods is appropriate at the associate's degree level and introductory exposure to basic issues involved in conducting research with elders provides a necessary backdrop to undergraduate programs. More in-depth understanding of gerontological research methods, particularly those involved in applied research, is a component of quality master's level programs. Finally, in-depth knowledge and the ability to apply distinctively gerontological research methods are necessary for conducting advanced original research at the doctoral level.     

TEACHNJ： An Evaluation of Two Years of Implementation

In July 2009, the Obama administration lauched its $4.35 billion Race to the Top （RTT） Fund, providing states with competitive grants in an effort to reform education. One of the main conditions of this program was to award educational innovation. With this in mind, states enacted new legislation in the hopes of attracting more funding for their proposed programs. Although there were many levels of reform targeted by the RTT, of significance to this research is the emphasis placed on improving teacher effectiveness and measuring teacher performance via evaluation systems. The Teacher Effectiveness and Accountability for the Children of New Jersey （TEACHNJ） Act was adopted by the New Jersey legislature in August 2012 with the intent to raise student achievement by improving the quality of instruction. This research explores the impact the TEACHNJ Act has on teacher evaluations and professional development. A survey was administered to 1,235 public school teachers in New Jersey to ascertain teacher perceptions of the： （a） evaluation system in their school; （b） level of communication between teachers and administrators; and （c） availability, frequency, and effectiveness of professional development opportunities. The response rate was 21%. We found that formal evaluations are conducted infrequently with a varying degree of accuracy and impact. Nearly half of the teachers indicated that formal evaluations did not lead to improvements in their classroom. A majority of teachers questioned the administrative value of formal teacher evaluations, in particular the rewards and sanctions associated with the outcome of evaluations and a concem that poor performers were not sanctioned nor were effective teachers rewarded. We found that teachers perceive the greatest value to professional development, which is derived from peer mentoring and observations. We also found that professional development is the most effective when it is offered onsite, embedded in the classroom, continuous, and sustained over ti     

Facilitating communities of practice as social learning systems: a case study of trialling sustainable sanitation at the University of Technology Sydney (UTS)

While social learning is advocated as critical for inducing large-scale shifts toward sustainability, methodological issues associated with designing the opportunities for social learning or guidelines for practitioners seeking to facilitate such learning in cross-disciplinary teams working on sustainability-oriented projects are lacking. This paper draws on a two-year pilot project in Sydney, in which government, industry and academic partners collaborated to learn about the development potential of urine diversion (UD) systems in practice. The concept of ‘Communities of Practice’ was used to identify inherent challenges and opportunities for social learning. An outcome of the project has been the identification of overarching principles for designing opportunities for social learning in such projects, particularly the need (1) to facilitate community-oriented leadership, (2) to develop strategic exercises for collaborative engagement and (3) involvement of actors beyond the boundaries of the experiment to introduce novelty, diversity and cumulative learning opportunities.
