Time Spent Gaming and Social Competence in Children: Reciprocal Effects Across Childhood

Electronic games are popular and many children spend much time on this activity. Here we investigate whether the quantity of time children spend on gaming is related to their social development, making this the first study to examine this relationship in children. We examine prospective relations between time spent gaming and social competence in a community sample of Norwegian 6 year olds (n = 873) followed up at ages 8, 10, and 12, controlling for socioeconomic status, body mass index, and time spent gaming together with friends. Results revealed that greater social competence at both 8 and 10 years predicted less gaming 2 years later and that more age-10 gaming predicted less social competence at age 12 but only among girls.     

Quality Assurance and Evaluation through Brazilian lenses: an exploration into the validity of umbrella concepts

In our present research we address the question of whether it is valid to apply the Quality Assurance and Evaluation (QAE) umbrella concept, which was formulated to explain new phenomena in European educational governance, to similar developments in Brazilian basic education. This led us to reflect on the possible pitfalls and potential strengths of using umbrella concepts as analytical tools. This article presents this exploration and its operationalisation. We confronted in-built assumptions in QAE with the contested, consensual and creative use of the notion of quality in Brazilian basic education, and looked for relationships. Our analysis shows that the Brazilian developments reiterate the relationships concerning global interconnectivity, and challenges those pertaining to conformity. We argue that the main risks of using umbrella concepts seem to concern the re-production of understandings, which frequently leads to the disregarding of deviation.     

Alternating current-dielectrophoresis driven on-chip collection and chaining of green microalgae in freshwaters

The capability of the AC dielectrophoresis (DEP) for on-chip capture and chaining of microalgae suspended in freshwaters was evaluated. The effects of freshwater composition as well as the electric field voltage, frequency, and duration, on the dielectrophoretic response of microalga Chlamydomonas reinhardtii were characterized systematically. Highest efficiency of cell alignment in one-dimensional arrays, determined by the percentage of cells in chain and the chain length, was obtained at AC-field of 20 V mm⁻¹ and 1 kHz applied for 600 s. The DEP response and cell alignment of C. reinhardtii in water sampled from lake, pond, and river, as well as model media were affected by the chemical composition of the media. In the model media, the efficiency of DEP chaining was negatively correlated to the conductivity of the cell suspensions, being higher in suspensions with low conductivity. The cells suspended in freshwaters, however, showed anomalously high chaining at long exposure times. High concentrations of nitrate and dissolved organic matter decrease cell chaining efficiency, while phosphate and citrate concentrations increase it and favor formation of longer chains. Importantly, the application of AC-field had no effect on algal autofluorescence, cell membrane damage, or oxidative stress damages in C. reinhardtii.     

Acute intraocular pressure changes during isometric exercise and recovery: The influence of exercise type and intensity,and participant´s sex

ABSTRACT

We assessed the intraocular pressure (IOP) behaviour during a 1-minute period of isometric physical effort and the immediate 1-minute of recovery in the mid-thigh clean pull and squat exercises at three different intensities. Twenty physically active individuals performed the isometric mid-thigh clean pull and squat exercises at three intensities (0% [low-intensity], 25% [medium-intensity] and 50% [high-intensity] of the maximum isometric force). IOP was semi-continuously measured by rebound tonometry. There was a statistically significant effect of exercise intensity on IOP (p < 0.001, ?_p² = 0.416), observing that IOP increments were positively associated with exercise intensity. The mid-thigh clean pull and squat exercises did not demonstrate differences (p = 0.510), and also, no differences were observed between men and women (p = 0.683). The IOP changes during the isometric physical effort showed a positive linear behaviour in all conditions (r = 0.70 to 0.96). IOP returned to baseline levels after 8 seconds of recovery. Our data showed a progressive and instantaneous IOP increment during isometric exercise, which was positively associated with exercise intensity. IOP changes were independent on the type of exercise and participant´s sex. After exercise, IOP rapidly (≈ 8 seconds) returned to baseline levels.     

The relevance of innovative school architecture for school principals

In many cases, innovative forms of learning require innovative concepts of using space in school. However, so far there has been a lack of research concerning the perspectives of school principals as important stakeholders in the adoption of alternative school architecture. The present study examines the importance of alternative school architecture in a sample of 1164 principals (56% females, mean-age 52.7 years) in Austria. An online questionnaire was conducted, containing questions about the school building, innovative forms of learning, and principals’ level of information, perceptions, and thoughts on the relevance of school architecture, as well as their motivation and self-efficacy. Results showed that principals are aware of the advantages of certain architectural elements, although these elements have been implemented in only a few schools. A high proportion of respondents report a lack of information about configurations of space that go beyond the traditional corridor-scheme. We conclude that although principals are in general open for the alternative configuration of space further efforts have to be made to overcome the obstacles that prevent principals from launching new concepts of using space, which are a lack of competitive resources and knowledge as well as an inadequate professional network.     

Implications of academic literacies research for knowledge making and curriculum design

This article explores the issue of what academic literacies research can bring to the study of knowledge and curriculum in higher education from a theoretical perspective and by means of illustrations from a work in progress academic literacies research project in the natural sciences. It argues that reading and writing are central to the process of learning in any discipline and that discipline specialists need to take this into consideration when planning their curricula. It also considers what knowledge means in the context of academic literacies research and how this conception of knowledge may differ from the knowledge structures researchers’ concern with knowledge as an object with its own properties. It comes to the conclusion that academic literacies research with its ethnographic-type exploration of social practice and theorisations of knowledge in the knowledge structures research can complement one another because each field of enquiry brings a lens that the other lacks.     

Students at risk: perceptions of Serbian teachers and implications for teacher education

While legislation is in place for the promotion of inclusive education in Serbia, the adoption of teaching practices that support diversity in schools is still lacking. This study looks at teacher perceptions of students at risk (SaR), their relationships with peers and the teachers’ own roles as sources of support, using a sample of 94 interviews with teachers analysed using qualitative content analysis. The SaR from Roma population and poor backgrounds are found to be perceived positively by their teachers, but most teachers failed to perceive their influence on the improvement of academic performance and peer relationships. Perceptions of students with disabilities varied in tone across the dimension positive-depending on the type of disability-negative. Teachers who spoke affirmatively about them expressed readiness to cooperate with parents and colleagues, emphasising the importance of socialisation. Recommendations for teacher education are discussed, including diversity awareness and encouraging more flexible understanding of teacher roles.     

Reaching Additional Users with Proactive Chat

ABSTRACT

Despite a general decline in recent years in academic libraries’ reference desk statistics, research indicates that library users continue to have complex research questions but are largely unaware that librarians are waiting and ready to assist them. The challenge for librarians is to connect with users at their point of need. At Bowling Green State University, we are making a move in this direction with proactive (pop-up) chat widgets embedded within our library Web pages, catalog, and databases. Since implementation, the number of chat reference questions received has more than doubled, helping us reach additional users from on-and off-campus.     

Do Formalized Gatekeeping Procedures Increase Programs' Follow‐Up With Deficient Trainees?

The authors investigated whether formalized gatekeeping procedures and program‐level characteristics influence the rates at which deficient trainees are graduated from counseling programs. One hundred eighteen faculty members reported that counselor educators face diverse pressures to avoid investigating potentially deficient students, including concerns about being sued and concerns about receiving compromised teaching evaluations. However, faculty members in programs accredited by the Council for Accreditation of Counseling and Related Educational Programs and faculty members in programs with more formalized gatekeeping procedures seemed to more effectively follow through with concerns they had about specific students. These findings support the implementation of both broad, program‐wide training standards and specific, formalized procedures to more effectively screen deficient trainees.     

Acute intraocular pressure responses to high-intensity interval-training protocols in men and women

We aimed (1) to test the acute impact of two high-intensity interval-training (HIIT) protocols differing in the level of effort on intraocular pressure (IOP) responses, and (2) to elucidate whether the IOP responses differ between men and women. Twenty-four physically active collegiate (12 men and 12 women) performed three protocols: low-fatigue HIIT (eight 30-m sprints with 60-s of rest), high-fatigue HIIT (eight 30-m sprints with 30-s of rest), and control (walking). IOP was taken at baseline, after sprints and recovery by rebound tonometry. Our data revealed an acute IOP reduction during both HIIT protocols compared to the control condition (effect size [ES]:0.81–1.65). The differences between both HIIT protocols were generally negligible (ES<0.30), however, the reduction of IOP was moderately higher for the low-fatigue HIIT protocol after the 7th (ES: 0.67) and 8th (ES: 0.74) sprints. Women showed a more prominent lowering effect on IOP during the control condition (ES: 0.42–1.02), and during the two first sprints of both HIIT protocols (ES: 0.54–1.03). These findings highlight that a time-efficient HIIT protocol may acutely reduce IOP levels, while low-fatigue HIIT protocol could be recommended since it induced a higher reduction on IOP than the high-fatigue HIIT protocol.
