Is ADHD a ‘real’ disorder?

In many western countries, attention deficit hyperactivity disorder (ADHD) has achieved celebrity status, such that it probably no longer requires introduction. The disorder is a global phenomenon, spreading rapidly as result of the increasing dominance internationally of US psychiatric models, the need for new markets for major pharmaceutical companies, increasing use of the internet by parents and professionals and changing approaches to schooling. There is a broad consensus among international experts and organisations that ADHD is a genuine neurodevelopmental disorder based on empirical research. However, many critics have questioned the legitimacy of ADHD. This paper reviews the arguments for and against the ADHD construct. First, the review examines the literature and research endorsing ADHD as a ‘real’ disorder. Second, the criticisms levelled against the ADHD construct are examined.     

Transport sector training in Ecuador

In less developed countries, like Ecuador, there is often a lack of adequately trained professionals working in the transport sector, particularly in the public authorities. This paper reports on the achievements of a project, supported by the British Overseas Development Administration, which has established a postgraduate programme in transport planning and engineering at the Catholic University of Ecuador in Quito. This initiative has already produced a substantial body of trained professionals equipped with the technical skills needed to tackle Ecuador's transport problems and the ability to recognise and develop appropriate policies and programmes. Additionally, the project is helping to create a self-sufficient Centre for Transport Research based in Quito.     

Substance abuse and serious child mistreatment: prevalence, risk, and outcome in a court sample

This study examined the prevalence and specific types of substance abuse in a sample of 206 cases of serious child abuse or neglect brought before a metropolitan juvenile court on care and protection petitions. In 43% of the cases, at least one of the parents had a documented problem with either alcohol or drugs, a figure which rose to 50% when alleged instances of substance abuse were included. Alcohol, cocaine, and heroin were the three most frequently mentioned abused substances. Parents with documented substance abuse were significantly more likely than nonsubstance-abusing parents to have been referred previously to child protective agencies, to be rated by court investigators as presenting high risk to their children, to reject court-ordered services, and to have their children permanently removed. When the two factors of court investigator high risk ratings and presence of parental substance abuse were combined, it was possible to obtain even higher levels of prediction of which parents would reject services and have their children permanently removed. Results suggest (1) the importance of increased screening, evaluation, and treatment of parental substance abuse in cases of serious child mistreatment; and (2) the possibility of adopting a predictive approach as to which families will be able to respond to court-ordered treatment requests and have their children returned.     

Exploring the Probabilities of ‘Who Wants to be a Millionaire?’

This article discusses three probabilistic scenarios based on the television game show ‘Who Wants to be a Millionaire?’. These situations provide motivational opportunities for high‐school students to explore the concepts of expected value, permutations and independent events.     

Who benefits? What benefits? Part-time postgraduate study in health and human services

Part-time postgraduate students make up a significant proportion of the student population, yet their experience remains poorly understood. In this article, a multi-phase, explanatory mixed-method study conducted within Tasmanian health and human services provides some answers. Students reported improved job performance, self-esteem and increased motivation to learn as primary outcomes. Other benefits of significance included an increased ability to manage change and increased job satisfaction. At the other end of the scale, fewer than half of all respondents agreed that part-time postgraduate study led to increased pay or remuneration, and only one-quarter of respondents believed their study led to improvements in personal relationships. There were significant associations between organisational placement and perceptions of benefit. The managers of those who were studying were less likely to perceive either increased job satisfaction or improved job performance in their subordinates. Amongst postgraduate, mature-age, part-time student respondents, their prior experience in higher education, professional background, seniority in the organisation, age and gender were also associated with differing perceptions of the benefits of higher education. These results add to the body of knowledge around the human, social and identity capital benefits associated with lifelong learning, and this study provides guidance for students, employers and universities.     

Infants Rely More on Gaze Cues From Own‐Race Than Other‐Race Adults for Learning Under Uncertainty

Differential experience leads infants to have perceptual processing advantages for own‐ over other‐race faces, but whether this experience has downstream consequences is unknown. Three experiments examined whether 7‐month‐olds (range = 5.9–8.5 months; N = 96) use gaze from own‐ versus other‐race adults to anticipate events. When gaze predicted an event's occurrence with 100% reliability, 7‐month‐olds followed both adults equally; with 25% (chance) reliability, neither was followed. However, with 50% (uncertain) reliability, infants followed own‐ over other‐race gaze. Differential face race experience may thus affect how infants use social cues from own‐ versus other‐race adults for learning. Such findings suggest that infants integrate online statistical reliability information with prior knowledge of own versus other race to guide social interaction and learning.     

Why We Share: A Uses and Gratifications Approach to Privacy Regulation in Social Media Use

The contradiction between the stated preferences of social media users toward privacy and actual privacy behaviors has suggested a willingness to trade privacy regulation for social goals. This study employs data from a survey of 361 social media users, which collected data on privacy attitudes, online privacy strategies and behaviors, and the uses and gratifications that social media experiences bring. Using canonical correlation, it examines in detail how underlying dimensions of privacy concern relate to specific contexts of social media use, and how these contexts relate to various domains of privacy-protecting behaviors. In addition, this research identifies how specific areas of privacy concern relate to levels of privacy regulation, offering new insight into the privacy paradox. In doing so, this study lends greater nuance to how the dynamic of privacy and sociality is understood and enacted by users, and how privacy management and the motivations underlying media use intersect.
