Personal Bias or Government Bias? Testing the Hostile Media Effect in a Regulated Press System

This study examines the hostile media effect in relation topartisans’ perception of the slant of news coverage ina highly regulated press environment—Singapore. We foundthat partisans in Singapore perceived unbiased news to be infavor of the other side, while the nonpartisans perceived thesame news to be neutral. Our findings show that hostile mediaeffects can persist in a restricted press environment wherepeople are aware of the government's control of media coverage.We also found that partisans’ awareness of the government'scontrol of media information contributed to their perceptionof the article slant as well.

Tackling behaviour and attendance issues in schools in Wales: implications for training and professional development

In 2009, the Welsh Assembly Government published its Report on the review of behaviour and attendance in schools in Wales. The National Behaviour and Attendance Review (NBAR) in Wales was chaired by the author of this paper. Both the Review and the Welsh Assembly Government’s response contained recommendations related to the training and professional development needs of staff in schools and local authorities (LAs). A paper on the professional development needs of staff on behaviour and attendance based on the NBAR recommendations is published in the same edition of this journal. This follow‐up paper focuses upon the Welsh Assembly Government’s response to these recommendations and its implementation plan on which the author acted as the professional adviser. The Welsh Assembly Government accepted with cross‐party support that the training and professional development needs of teachers and LA staff in behavioural management and school attendance had been neglected over many years. For the first time, coordinated new training and continuing professional development programmes on behavioural management and school attendance will be introduced in Wales soon. The next stage will be to evaluate the effectiveness of these programmes.     

Forget EPSSs: How You Can Marshal Mobile Geographic Information Systems (GISs) and Spatial Awareness for Performance Improvement

Mobile geolocation applications identify global coordinates of mobile devices and can be enriched with performance‐context data. This technology has potential to integrate job aids, learning bursts, and parts of manuals with work tools (such as checklists) at the point of performance to better support individual and team performance. Emerging uses of mobile geolocation allow human performance technologists to move from generic electronic performance support systems (EPSSs) to spatial support systems. These increase the potential for performers to access more context‐aware information at the time and space in which the actions occur. Mobile geolocation can also automatically send data about the performance to enterprise databases so that actions taken and the use of training or job aids at the point of performance can be tracked. This article explores how mobile geolocation functionality can be orchestrated to support performance, enrich enterprise databases, and aid human performance technologists.     

Assessment of total body water and its compartments in elite judo athletes: comparison of bioelectrical impedance spectroscopy with dilution techniques

Bioelectrical impedance spectroscopy (BIS) is an inexpensive and non-invasive technique to measure total body water (TBW), extracellular water (ECW), and intracellular water (ICW). The purpose of this study was to validate TBW, ECW and ICW assessed by BIS, using dilution techniques as the reference method (REF) in elite judo athletes. Thirty-two Portuguese elite male judo athletes were evaluated during a period of weight stability. TBW, ECW and ICW were assessed by BIS (Xitron 4000). Deuterium and bromide dilution techniques were used as the criterion method for measuring TBW and ECW, while ICW was calculated as the difference between the two. BIS explained 96%, 77% and 94% of the total variability from REFs for TBW, ECW and ICW, respectively. BIS also demonstrated high precision (ρ ≥ 0.88) and accuracy (C_b = 0.98), with a minimum concordance coefficient correlation of 0.87 for ECW. The mean bias demonstrated that BIS slightly overestimated the REF in 1.1 kg (2.3%), 0.3 kg (1.6%) and 0.8 kg (2.7%) for TBW, ECW and ICW, respectively. The 95% limits of agreement ranged from ?1.2 to 3.3 kg in TBW, from ?1.8 to 2.4 kg in ECW and from ?1.0 to 2.6 kg in ICW. A non-significant trend was found between the difference and the mean of reference and alternative methods. These findings highlight the efficacy of BIS as a valid non-biased tool for the assessment of TBW and its compartments in elite male judo athletes, during a period of weight stability.
