The impact of fire on habitat use by the short-snouted elephant shrew ('Elephantulus brachyrhynchus') in North West Province, South Africa

Several studies have investigated the response of small mammal populations to fire, but few have investigated behavioural responses to habitat modification. In this study we investigated the impact of fire on home range, habitat use and activity patterns of the short-snouted elephant shrew (Elephantulus brachyrhynchus) by radio-tracking individuals before and after a fire event. All animals survived the passage of fire in termite mound refugia. Before the fire, grassland was used more than thickets, but habitat utilization shifted to thickets after fire had removed the grass cover. Thickets were an important refuge both pre- and post-fire, but the proportion of thicket within the home range was greater post-fire. We conclude that fire-induced habitat modification resulted in a restriction of E. brachyrhynchus movements to patches of unburned vegetation. This may be a behavioural response to an increase in predation pressure associated with a reduction in cover, rather than a lack of food. This study highlights the importance of considering the landscape mosaic in fire management and allowing sufficient island patches to remain post-fire ensures the persistence of the small mammal fauna

A systematic review of recommended modifications of CBT for people with cognitive impairments following brain injury

Due to diverse cognitive, emotional and interpersonal changes that can follow brain injury, psychological therapies often need to be adapted to suit the complex needs of this population. The aims of the study were to synthesise published recommendations for therapy modifications following brain injury from non-progressive traumatic, vascular, or metabolic causes and to determine how often such modifications have been applied to cognitive behavioural therapy (CBT) for post-injury emotional adjustment problems. A systematic review and narrative synthesis of therapy modifications recommended in review articles and reported in intervention studies was undertaken. Database and manual searches identified 688 unique papers of which eight review articles and 16 intervention studies met inclusion criteria. The review articles were thematically analysed and a checklist of commonly recommended modifications composed. The checklist items clustered under themes of: therapeutic education and formulation; attention; communication; memory; and executive functioning. When this checklist was applied to the intervention studies, memory aids and an emphasis on socialising patients to the CBT model were most frequently reported as adaptations. It was concluded that the inconsistent reporting of psychological therapy adaptations for people with brain injury is a barrier to developing effective and replicable therapies. We present a comprehensive account of potential modifications that should be used to guide future research and practice

An empirical investigation of the channels that facilitate a total quality culture

It is generally agreed that the culture of an organisation is a function of its values, beliefs and behavioural practices and that the influence of culture on an organisation is powerful and pervasive. There is also broad agreement that total quality management (TQM ) is a management paradigm that propagates certain values, behaviour and working methods. Moreover, that the successful introduction and practice of a total quality management approach requires close attention to, and more often than not modification of, organisational culture. Yet, culture is somewhat intangible, and regardless of the precise cultural aspirations, in order to change or maintain the desired culture an organisation needs a set of facilitating channels. These are mechanisms or necessary conditions that influence, mould and help sustain a desirable cultural orientation. This paper examines the channels that facilitate the development of a total quality culture based on the findings of an investigation of an international sample of organisations widely regarded as leading exponents of TQM

From the clinic to the lab (and back) : a call for laboratory research to optimize cognitive-behaviour treatment of pain

Cognitive behavioural therapy (CBT) is the dominant psychological treatment for chronic pain. CBT covers a mixture of aims and a broad range of techniques, including attentional control, modification of maladaptive beliefs and coping strategies and flexible goal setting and acceptance. Patients are exposed to varying selections of these strategies, and a major challenge for clinical practice is to determine what works for whom in which context. We propose that incorporating laboratory research into translational behaviour medicine is a critical developmental step that will help optimizing CBT and provide examples of representative experimental research programs

The conceptualisation and measurement of DSM-5 Internet Gaming Disorder: the development of the IGD-20 Test

Background: Over the last decade, there has been growing concern about ‘gaming addiction’ and its widely documented detrimental impacts on a minority of individuals that play excessively. The latest (fifth) edition of the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM-5) included nine criteria for the potential diagnosis of Internet Gaming Disorder (IGD) and noted that it was a condition that warranted further empirical study. Aim: The main aim of this study was to develop a valid and reliable standardised psychometrically robust tool in addition to providing empirically supported cut-off points. Methods: A sample of 1003 gamers (85.2% males; mean age 26 years) from 57 different countries were recruited via online gaming forums. Validity was assessed by confirmatory factor analysis (CFA), criterion-related validity, and concurrent validity. Latent profile analysis was also carried to distinguish disordered gamers from non-disordered gamers. Sensitivity and specificity analyses were performed to determine an empirical cut-off for the test. Results: The CFA confirmed the viability of IGD-20 Test with a six-factor structure (salience, mood modification, tolerance, withdrawal, conflict and relapse) for the assessment of IGD according to the nine criteria from DSM-5. The IGD-20 Test proved to be valid and reliable. According to the latent profile analysis, 5.3% of the total participants were classed as disordered gamers. Additionally, an optimal empirical cut-off of 71 points (out of 100) seemed to be adequate according to the sensitivity and specificity analyses carried

Understanding Social and Behaviour Change Communication

terms that should be understood first, as different words and second as an entity. SBCC is primarily a brand of communication that has long existed in the social and behavioural disciplines; in the social sciences and humanities. It is also a field of study that is strongly anchored on theories of human behaviour and the philosophies of human existence with the aim of bringing about a transformation of the negative human behaviour through the ecological system. Behaviour change specifically has attracted the concerns of economists and advertisers. Economists are concerned about human needs and wants as determined by human behavio

The listening talker: A review of human and algorithmic context-induced modifications of speech

International audienceSpeech output technology is finding widespread application, including in scenarios where intelligibility might be compromised - at least for some listeners - by adverse conditions. Unlike most current algorithms, talkers continually adapt their speech patterns as a response to the immediate context of spoken communication, where the type of interlocutor and the environment are the dominant situational factors influencing speech production. Observations of talker behaviour can motivate the design of more robust speech output algorithms. Starting with a listener-oriented categorisation of possible goals for speech modification, this review article summarises the extensive set of behavioural findings related to human speech modification, identifies which factors appear to be beneficial, and goes on to examine previous computational attempts to improve intelligibility in noise. The review concludes by tabulating 46 speech modifications, many of which have yet to be perceptually or algorithmically evaluated. Consequently, the review provides a roadmap for future work in improving the robustness of speech output
