A Comparative Analysis of the Relative Effectiveness of Four Dynamic Lot-Sizing Techniques on Return on Investment

The relative performance of dynamic lot-sizing techniques has been of considerable interest to researchers in recent years. While research has addressed performance in terms of cost-effectiveness, researchers have not determined the impact of dynamic lot-sizing techniques on return on investment (ROI) as it applies to finished goods' schedules. The purpose of this research is to explore the relative performance of four dynamic lot-sizing techniques with regard to ROI, namely the Wagner-Whitin, Incremental Part Period, Silver-Meal, and Groff techniques. Computer graphics are employed to analyze the relative ROI effectiveness.     

Knowledge and Beliefs About Gambling in Australian Secondary School Students and their Implications for Education Strategies

This study investigated the nature of gambling-related knowledge and beliefs in a survey study of 2,669 students aged 13–17 years in South Australia. Students were classified as pathological gamblers, at risk, or not at risk based upon the DSM-IV-J, and their responses to questions relating to objective odds, probabilities, and common misperceptions were compared. The study confirmed previous studies which have shown that pathological gamblers are more susceptible to erroneous beliefs concerning randomness and chance, but do not differ in terms of their knowledge of objective odds. These findings were discussed in terms of Ladouceur’s notion of “cognitive switching” and the distinction drawn between “hot” and “cold” cognitions in clinical outcome studies. The implications for school-based education programs are examined with attention given to the potential value of role-playing and simulations in encouraging student reflection and self-awareness.     

Managerial audit and community mental health: a study of rationalising practices in Finnish psychiatric outpatient clinics

In many European welfare states the reform of mental health services has been accompanied by the implementation of new forms of governance, including the introduction of managerial audit systems. While such systems have been developed for ‘good causes’, such as quality assurance, financial management and monitoring staff performance, they may simultaneously produce diverse and contradictory effects on practice. The aim of this article is to examine the role of one managerial audit system, introduced in psychiatric outpatient clinics in central Finland, and assess its impact on practice. Reference is made to modernising mental health policy in the UK as that has producedsimilar practics outcomes. The research was an empirical study of practice using a mixed-method case study design involving documentary research and semi-structured interviews. Insights from Mitchell Dean's notion of governmentalisation of government were utilised in the analysis. It was found that, although the audit system primarily served administrative needs, it began to reshape practice by reinforcing certain modes of working and excluding others. The analysis of community mental health work in Finland, with similar trends in the UK, highlights the connection between documentation, resource allocation and managerial priorities that reinforce particular styles of practice. In community mental health services it would appear that the problems of professional practice have become the problems of administration.     

A Sex Difference in Mental Rotation in Infants: Convergent Evidence

Quinn and Liben (2008) reported a sex difference on a mental rotation task in which 3‐ to 4‐month‐olds were familiarized with a shape in different rotations and then tested with a novel rotation of the familiar shape and its mirror image. As a group, males but not females showed a significant preference for the mirror image, a pattern paralleled at the individual level (with most males but less than half the females showing the preference). Experiment 1 examined a possible explanation for this performance difference, namely, that females were more sensitive to the angular differences in the familiarized shape. Three‐ to 4‐month‐olds were given a discrimination task involving familiarization with a shape at a given rotation and preference testing with the shape in the familiarized versus a novel rotation. Females and males preferred the novel rotation, with no sex difference observed. This finding did not provide support for the suggestion that the sex difference in mental rotation is explained by differential sensitivity to angular rotation. Experiment 2 revealed that the sex difference in mental rotation is observed in 6‐ to 7‐month‐olds and 9‐ to 10‐month‐olds, suggesting that a sex difference in mental rotation is present at multiple ages during infancy.     

Kulturen und Spiralen des „Eigentlich“. Hierarchisch gesteuerte Veränderungsprozesse am Beispiel nachgelagerter Dienststellen des österreichischen Bundesministeriums für Bildung

Amidst the current debates on education, in Austria the former academies of the compulsory and vocational teachers’ training shall be transformed to educational “colleges” or even “universities”. The Federal Ministry is driving this process top-down, first and foremost tackling the manifest structures. This gradually unsheathes a latent “culture of eigentlich” within the affected educational institutions. It turns out that this culture, which is functional for the system in dealing with ambiguous, contradictory, or even unattainable requirements, does not disappear, but that it rather absorbs and transforms the manifest demands “from top” in practice “at the bottom”. This again provokes hierarchical interventions top-down, and eventually leads to self-enforcing dynamics between manifest and latent structures, fuelling the spiralling process.     

Gender Differences in the Presentation of Observable Risk Indicators of Problem Gambling

In many countries where gambling is legalised, there has been a strong public policy focus on the need for strategies to reduce gambling related harm. These have often included policies requiring staff in gambling venues to identify and/or assist people who might be experiencing gambling-related harm. To facilitate this process, researchers have developed visible behavioural indicators that might be used to profile potentially problematic gambling. Few of these studies have, however, examined whether such indicators or ‘warning signs’ might differ between men and women. In this study, we describe the results of an analysis of data drawn from 1185 fortnightly gamblers that included 338 problem gamblers as classified by the Problem Gambling Severity Index. Indicators of problem gambling were similar between males and females with a few key exceptions. Indicators reflecting emotional distress were more commonly reported by females with gambling problems, whereas problem gambling males were more likely to display aggressive behaviour towards gambling devices and others in the venue. Amongst males, signs of emotional distress as well as attempts to conceal their presence in venues from others most strongly differentiated between problem and non-problem gamblers. Amongst females, signs of anger, a decline in grooming and those attempts to access credit were the most distinguishing indicators. These findings have implications for the refinement of identification policies and practices.     

Does the Modernization of Environmental Enforcement Reduce Toxic Releases? An Examination of Self-policing,Criminal Prosecutions,and Toxic Releases in the United States, 1988–2014

According to modernization theory, enforcement schemes that rely on end-of-the-pipe regulation are not as effective at achieving improved environmental performance as market-based approaches that encourage pollution prevention. Consistent with that observation, the U.S. Environmental Protection Agency transitioned to the use of self-policing to encourage pollution prevention. Other studies note that environmental compliance is significantly affected by traditional “command-and-control” strategies. Using Prais Winston regression we examine these contrasting views by estimating the relationship between toxic releases, self-policing, and criminal prosecutions from 1988 through 2014. Initial correlations suggest that (1) self-policing is not associated with toxic releases but that (2) criminal prosecutions may reduce toxic releases through general deterrence signals. Subsequent analyses controlling for gross domestic product revealed that neither self-policing nor criminal enforcement correlate with toxic releases but that gross domestic product was the strongest predictor of emissions. The implications of these findings for the control of toxic emissions are discussed.     

Evidence of Big Five and Aggressive Personalities in Gait Biomechanics

Behavioral observation techniques which relate action to personality have long been neglected (Furr and Funder in Handbook of research methods in personality psychology, The Guilford Press, New York, 2007) and, when employed, often use human judges to code behavior. In the current study we used an alternative to human coding (biomechanical research techniques) to investigate how personality traits are manifest in gait. We used motion capture technology to record 29 participants walking on a treadmill at their natural speed. We analyzed their thorax and pelvis movements, as well as speed of gait. Participants completed personality questionnaires, including a Big Five measure and a trait aggression questionnaire. We found that gait related to several of our personality measures. The magnitude of upper body movement, lower body movement, and walking speed, were related to Big Five personality traits and aggression. Here, we present evidence that some gait measures can relate to Big Five and aggressive personalities. We know of no other examples of research where gait has been shown to correlate with self-reported measures of personality and suggest that more research should be conducted between largely automatic movement and personality.     

Children,Poverty and the Sustainable Development Goals

The Sustainable Development Goals (SDGs) came into force in January 2016, taking over from the Millennium Development Goals (MDGs). Significant human development progress has occurred in recent decades. Nevertheless, the MDGs have been criticised not least for failing to prioritise inequality and gains for the poorest people. The SDGs create a much more comprehensive agenda and support many key child rights concerns. While SDGs reflect an important global consensus, their delivery depends upon national action.
