The influence of external stimulation on airflow detection by children with asthma

Abstract

The relevance and significance of the concept of a ‘competition of cues’ for the understanding of symptom perception in childhood asthma was investigated during detection of externally applied resistive loads on breathing. The concept predicts that subjects would respond less frequently and less accurately during external stimulation. The sample consisted of 36 children with and 36 without asthma, aged 7-18 years. Detection of airflow was measured in a neutral and in an external stimulation condition. The children breathed through a facemask and responded to changes in airflow by pressing a button. The stimulus presented and withdrawn was analogous to a decrease in lung function (Forced Expiratory Volume in one second) of 39%. Accuracy of detection of airflow was defined as correct minus false positive responses to load stimuli.

The results showed that children with and without asthma responded significantly less frequently during external stimulation than in the neutral condition. However, the accuracy of detection among non-asthmatics was not affected by external stimulation. Children with asthma responded significantly more accurately during external stimulation. The results are discussed in the light of children's accuracy to perceive actual airways obstruction.     

Causal Attribution: Analysis of Patterns and Influencing Factors Among Learners at a Higher Education Institution

The study explored the academic patterns and implications of academic attributions made by students who had been given test feedback at a higher learning institution in Zimbabwe. A random sample of 8 (female = 4; male= 4; mean age = 21.9, passed a test = 4; failed the test = 4) participants was purposefully selected from a class of second year students majoring in psychology and human resources management. Audio-taped semi-structured interviews were conducted to collect data. Thematic content analysis was used to analyse data. Results indicate that culture and gender moderate academic causal attributions.     

Politicised religion and the religionisation of politics

The dilemmas of dealing with difference are currently at the heart of our society. Among the anomalies of our age is the survival and even flourishing of complex systems of values based on religion. However, we see that mosques flourish, ethnic associations with religious undertones multiply and religion is present in the public sphere through conflicts about religion or persons believed to be religious. Islam is a much discussed topic. The line between private and public religion is as thin as ever, and I would argue so is the line between religion and politics. This can be observed at two levels. First, the invocation of religion in the political discourse, leading to the politicisation of religion and second, as the influence religion has on political life, the religionisation of politics.     

Health Literacy,Health Inequality and a Just Healthcare System

Limited health literacy is a pervasive and independent risk factor for poor health outcomes. Despite decades of reports exhibiting that the healthcare system is overly complex, unneeded complexity remains commonplace and endangers the lives of patients, especially those with limited health literacy. In this article, we define health literacy and describe the empirical evidence associating health literacy and poor health outcomes. We recast the issue of poor health literacy from within the ethical perspective of the least well-off and argue that poor health outcomes deriving from limited health literacy ought to be understood as a fundamental injustice of the healthcare system. We offer three proposals that attempt to rectify this injustice, including: universal precautions that presume limited health literacy for all healthcare users; expanded use of technology supported communication; and clinical incentives that account for limited health literacy.     

The effects of safety behavior availability versus utilization on inhibitory learning during exposure

ABSTRACT

This study re-analyzes data from Sy and colleagues (2011; Behaviour Research and Therapy, 49, 305–314) comparing safety behavior availability (SBA) to safety behavior utilization (SBU) during exposure therapy for claustrophobic concerns. The present investigation assessed differential rates of inhibitory learning (i.e. change in danger expectancy and coping self-efficacy) between SBA and SBU before, during, and after a single-session treatment. Thirty-nine participants with marked claustrophobic fear completed six consecutive 5-minute exposure trials in a claustrophobia chamber. Participants in the SBA condition exhibited more interference with inhibitory learning relative to the SBU condition. Danger expectancy was significantly higher in the SBA group and decreased at a markedly slower rate across exposure trials relative to SBU. Coping self-efficacy was also significantly lower among participants in the SBA condition, although groups demonstrated similar rates of change across trials. Limitations, clinical implications, and future directions are discussed.     

Safety Behaviour Enhances the Acceptability of Exposure

Compulsive washing and contamination fears are among the most common symptoms of obsessive-compulsive disorder (OCD). Research suggests that exposure and response prevention (ERP) is effective for OCD. However, ERP is prone to dropouts and refusals, and a substantial proportion of clients therefore do not receive the care they need. A proposed solution involves the judicious use of safety behaviour to enhance the acceptability of exposure-based interventions. The current study aimed to test this proposed solution. Participants were 70 undergraduate students who completed two exposure exercises for contamination fear, one with safety behaviour and one without. Participants then rated the acceptability of the two exercises. Exposure with safety behaviour (ESB) was rated as significantly more acceptable than ERP. Furthermore, subjective fear ratings were lower and behavioural approach to a series of contaminants was greater in the ESB condition. Results demonstrated the acceptability-enhancing potential of safety behaviour in exposure, and are discussed in terms of both theoretical and practical aspects of safety behaviour, exposure, and evidence-based interventions for anxiety disorders.

Perception of threat and safety at work among employees in the Norwegian ministries after the 2011 Oslo bombing

Background and objectives: Terrorism can heighten fears and undermine the feeling of safety. Little is known, however, about the factors that influence threat and safety perception after terrorism. The aim of the present study was to explore how proximity to terror and posttraumatic stress reactions are associated with perceived threat and safety after a workplace terrorist attack. Design and methods: A cross-sectional questionnaire survey was administered to employees in 14 of 17 Norwegian ministries 9–10 months after the 2011 bombing of the government headquarters in Oslo (n = 3520). Results: About 198 of 1881 employees completing the survey were at work when the bomb exploded. Regression analysis showed that this high-exposed group had elevated perceived threat (β = 0.36; 95% CI = 0.19 to 0.53) and reduced perceived safety (β = ?0.42; 95% CI = ?0.62 to ?0.23) compared to a reference group of employees not at work. After adjusting for posttraumatic stress reactions, however, proximity to the explosion no longer mattered, whereas posttraumatic stress was associated with both high perceived threat (β = 0.55; 95% CI = 0.48 to 0.63) and low perceived safety (β = ?0.71; 95% CI, ?0.80 to ?0.63). Conclusion: Terror-exposed employees feel more threatened and less safe after a workplace terrorist attack, and this is closely linked to elevated levels of posttraumatic stress reactions.     

Why Do Police Arrest Victims of Domestic Violence? The Need for Comprehensive Training and Investigative Protocols

After all the positive changes in the criminal justice system over the last ten to fifteen years concerning the response to incidents of domestic violence, there remains the problem of battered women who are arrested as perpetrators of domestic violence. The reasons for these arrests are complex and varied. They range from the patriarchal structure of criminal justice agencies, to the staffing of these agencies, and finally to the inappropriate and inadequate training of police officers. This article includes real life examples of cases where victims were arrested, and why these arrests occurred. It also includes suggestions on how to minimize these illegal arrests.     

Violence against Women in Contemporary Ghanaian Society

Abstract

Overcoming violence against women requires critical reflective questioning both by individuals and human societies. At stake are not just questions of whether we respond to situations of violence but more importantly, where, when and how we respond. This paper examines the problem with respect to new dimensions arising from existing interventions on violence against women in the Ghanaian context. It calls for well-planned and sustained strategies to help break the cycle of violence being created.

The paper also calls upon the Church to look within its own resources for strategies that are life transforming to help break the vicious cycle. It notes that the Church is not only well placed to respond appropriately but it has been commissioned and given the requisite tools to do so. The call is therefore for the Church to enlist these foundational resources available to it and to put them to good use as it is demanded by its calling.
