Changes in corticomotor excitation and inhibition during prolonged submaximal muscle contractions

Abstract: Changes in motor evoked potential (MEP) amplitude, post-MEP silent period duration, and interpolated twitch torque were measured using transcranial magnetic (TMS) and electrical (TES) stimulation during a 20% maximum voluntary contraction of the elbow flexors sustained to exhaustion TMS- and TES-induced MEP amplitude increased progressively over the contraction period up until the point of exhaustion The TMS-induced silent period was prolonged only during the second half of the contraction period, the time course being different from that of the MEP responses, whereas the TES-induced silent period did not change The findings indicate that corticomotor excitability increases during a sustained submaximal voluntary contraction and that, as fatigue develops, there is a progressive buildup of intracortical inhibition This may represent a mechanism whereby corticomotor output is maintained at an appropriate level to preserve optimal motor unit firing frequencies during a fatiguing contraction

Longitudinal impact of the Cyber Friendly Schools program on adolescents' cyberbullying behavior.

Abstract: Cyberbullying is a major public health problem associated with serious mental, social, and academic consequences for young people. To date, few programs addressing cyberbullying have been developed and empirically tested. The Cyber Friendly Schools (CFS) group-randomized controlled trial measured the longitudinal impact of a whole-school online cyberbullying prevention and intervention program, developed in partnership with young people. Non-government secondary schools in Perth, Western Australia, (N = 35; 3,000+ students) were randomized to an intervention (n = 19) or usual practice control group (n = 16 schools). Students completed online questionnaires in 2010, 2011, and at 1-year follow-up in 2012, measuring their cyberbullying experiences during the previous school term. The intervention group received the program in Grades 8 and 9 (aged 13-14 years). Program effects were tested using two-part growth models. The program was associated with significantly greater declines in the odds of involvement in cyber-victimization and perpetration from pre- to the first post-test, but no other differences were evident between the study conditions. However, teachers implemented only one third of the program content. More work is needed to build teacher capacity and self-efficacy to effectively implement cyberbullying programs. Whole-school cyberbullying interventions implemented in conjunction with other bullying prevention programs may reduce cyber-victimization more than traditional school-based bullying prevention programs alone.

The movement ecology of seagrasses

Abstract: A movement ecology framework is applied to enhance our understanding of the causes, mechanisms and consequences of movement in seagrasses: marine, clonal, flowering plants. Four life-history stages of seagrasses can move: pollen, sexual propagules, vegetative fragments and the spread of individuals through clonal growth. Movement occurs on the water surface, in the water column, on or in the sediment, via animal vectors and through spreading clones. A capacity for long-distance dispersal and demographic connectivity over multiple timeframes is the novel feature of the movement ecology of seagrasses with significant evolutionary and ecological consequences. The space–time movement footprint of different life-history stages varies. For example, the distance moved by reproductive propagules and vegetative expansion via clonal growth is similar, but the timescales range exponentially, from hours to months or centuries to millennia, respectively. Consequently, environmental factors and key traits that interact to influence movement also operate on vastly different spatial and temporal scales. Six key future research areas have been identified.

Inhibitors to host community participation in sustainable tourism development in developing countries

Abstract: The involvement of host communities (or destination residents), particularly in developing countries, is critical to the success of tourism development and to the creation of a “Just Destination”. This paper investigates host community perceptions about obstacles to their participation in tourism development in Lombok, Indonesia, providing new insights into institutional influences on tourism opportunities and issues. Purposive and snowball sampling techniques targeted separate groups of destination residents who live in a developed tourism destination, a less developed tourism destination, a remote rural village far away from tourism destinations, as well as a group of university students. Data were collected through in-depth interviews, qualitative questionnaires and observation, and were analysed using content analysis. Results show three main institutional factors inhibit host community participation in tourism: tourism agencies, private sector providers and tourism infrastructure, and perceptions of ...

Forensic project management: The underlying causes of rework in construction projects

Abstract: Construction professionals recognize that rework is a significant factor contributing to poor project performance, yet little is known about its antecedents and consequently it remains an innate problem. Because factors that contribute to its occurrence are not fully understood, the derivation of appropriate strategies for its reduction is problematic. Therefore, a comprehensive appreciation of the mechanisms that cause rework will enable project performance improvements to be made. Two longitudinal case studies were undertaken to determine the antecedents of rework. Based on the findings presented, strategies for reducing the incidence of rework are identified and discussed. This paper contributes to study of quality in construction by identifying the underlying factors that influence rework in projects.
