Iran and the Shanghai cooperation organization : ideology and realpolitik in Iranian foreign policy

The Islamic Republic of Iran has pursued full membership in the Shanghai Cooperation Organisation (SCO). In doing so, Iran has appeared to be unfazed by the prospect of allying with Russia and China, two countries which have systematically suppressed their Muslim minorities for decades. Similarly, the SCO's Central Asian member states are led by individual leaders who are generally believed to rule in spite of their populations. As a result, Iran's eagerness to join the SCO may appear to contradict its self-promoted image as the champion of Muslim interests, but in reality it sits nicely within its overarching enmity for the USA. Indeed, the SCO is seen as a geopolitical counterweight to the USA. For Iran, this geopolitical opportunity overrides ideological imperatives, with the gap between ideology and geopolitics most evident under the presidency of Mahmoud Ahmadinejad.

An effective program design to support older workers with intellectual disability to participate individually in community groups

The foreshadowed increase of older people with intellectual disability has become a reality in many developed countries. As these adults age, improved quality of life can be achieved through applications of conjoint policy aims of inclusion and participation. A transition-to-retirement (TTR) program developed for employees of a large multisite disability employment service in Sydney, Australia, used these aims to effect successful partial retirement. The authors describe the program logic of the TTR, detailing its conceptual components as the first step to enabling it to be tested and replicated in other settings. The TTR program has three components: promoting the concept of retirement, laying the groundwork for inclusion of would-be retirees with intellectual disability in the community, and constructing the reality. The third component comprised five stages: planning, locating a group, mapping new routine, recruiting and training mentors, and monitoring and ongoing support. The project's participants were 24 older employees, who replaced 1 day a week of work with membership of a community group and were supported by mentors who facilitated involvement of the participants in their group. Data collected provided information on the implementation of the program, the time and costs expended, and challenges encountered. Key to the model was a coordinator, skilled in generic case management and specific disability interventions (such as active support), who collaborated with others to manage the program. The authors note that by detailing the program logic underpinning the TTR program, they have exposed the hidden work of supporting meaningful inclusion of people with intellectual disability in community groups and added to the limited stock of evidence-informed programs in this area. © 2014 International Association for the Scientific Study of Intellectual and Developmental Disabilities and Wiley Periodicals, Inc.

Re-thinking continuing professional development through changing metaphors and location in professional practices

Many professions have requirements for professional development activities to ensure continuing registration or membership. These commonly focus on participation in a limited range of activities. This paper questions the assumptions behind such approaches and what alternatives might be considered. It explores the suitability of metaphors used for continuing professional education and suggests that continuing professional development might be better conceptualised within practice theory. It identifies what a practice theory view of continuing professional development might involve and discusses the implications, particularly the notion of locating development within the practices of work.

Facilitated communication and authorship: a systematic review

Facilitated Communication (FC) is a technique whereby individuals with disabilities and communication impairments allegedly select letters by typing on a keyboard while receiving physical support, emotional encouragement, and other communication supports from facilitators. The validity of FC stands or falls on the question of who is authoring the typed messages--the individual with a disability or the facilitator. The International Society for Augmentative and Alternative Communication (ISAAC) formed an Ad Hoc Committee on FC and charged this committee to synthesize the evidence base related to this question in order to develop a position statement. The purpose of this paper is to report this synthesis of the extant peer-reviewed literature on the question of authorship in FC. A multi-faceted search was conducted including electronic database searches, ancestry searches, and contacting selected authors. The authors considered synopses of systematic reviews, and systematic reviews, which were supplemented with individual studies not included in any prior reviews. Additionally, documents submitted by the membership were screened for inclusion. The evidence was classified into articles that provided (a) quantitative experimental data related to the authorship of messages, (b) quantitative descriptive data on the output generated through FC without testing of authorship, (c) qualitative descriptive data on the output generated via FC without testing of authorship, and (d) anecdotal reports in which writers shared their perspectives on FC. Only documents with quantitative experimental data were analyzed for authorship. Results indicated unequivocal evidence for facilitator control: messages generated through FC are authored by the facilitators rather than the individuals with disabilities. Hence, FC is a technique that has no validity.

A noisy-smoothing relevance feedback method for content-based medical image retrieval

In this paper, we address a new problem of noisy images which present in the procedure of relevance feedback for medical image retrieval. We concentrate on the noisy images, caused by the users mislabeling some irrelevant images as relevant ones, and a noisy-smoothing relevance feedback (NS-RF) method is proposed. In NS-RF, a two-step strategy is proposed to handle the noisy images. In step 1, a noisy elimination algorithm is adopted to identify and eliminate the noisy images. In step 2, to further alleviate the influence of noisy images, a fuzzy membership function is employed to estimate the relevance probabilities of retained relevant images. After noisy handling, the fuzzy support vector machine, which can take into account different relevant images with different relevance probabilities, is adopted to re-rank the images. The experimental results on the IRMA medical image collection demonstrate that the proposed method can deal with the noisy images effectively.

Reflections on being a first generation self-advocate: belonging, social connections, and doing things that matter

Background Despite good policy intentions, people with intellectual disability continue to be socially excluded. Social geographers suggest the potential of self-authored spaces as catalysts for social inclusion. One such space, self-advocacy, is commonly perceived as part of a political movement for social change rather than a vehicle for social inclusion of its members. This paper investigated what involvement in self-advocacy has meant to long-term members of a self-advocacy group in Victoria, Australia. Methods In-depth interviews were conducted with 12 self-advocates about their reflections on involvement in the group. These data together with the commentary of 5 self-advocates during interviews with 18 self-advocacy supporters about their recollections of involvement in the group were transcribed and analysed thematically. Findings Through their involvement in self-advocacy, members of the group had gained a sense of belonging, social connections, and purposeful occupation, which included paid project work, lobbying, and organisational leadership and management. Conclusions This study suggests that self-advocacy groups can be places that foster social inclusion, potentially offering “membership” of an exclusive group, a wider social movement and of mainstream society.

Clustering of diet, physical activity and sedentary behaviour among Australian children: cross-sectional and longitudinal associations with overweight and obesity

BACKGROUND/OBJECTIVES: Evidence suggests diet, physical activity (PA) and sedentary behaviour cluster together in children, but research supporting an association with overweight/obesity is equivocal. Furthermore, the stability of clusters over time is unknown. The aim of this study was to examine the clustering of diet, PA and sedentary behaviour in Australian children and cross-sectional and longitudinal associations with overweight/obesity. Stability of obesity-related clusters over 3-years was also examined. SUBJECTS/METHODS: Data were drawn from the baseline (T1: 2002/03) and follow-up waves (T2: 2005/06) of the Health Eating and Play Study. Parents of Australian children aged 5-6 (n=87) and 10-12 years (n=123) completed questionnaires. Children wore accelerometers and height and weight were measured. Obesity-related clusters were determined using K-medians cluster analysis. Multivariate regression models assessed cross-sectional and longitudinal associations between cluster membership, and BMI z-score and weight status. Kappa statistics assessed cluster stability over time. RESULTS: Three clusters, labelled 'most Healthy', 'Energy-dense (ED) consumers who watch TV' and 'high sedentary behaviour/low moderate-to-vigorous physical activity' were identified at baseline and at follow-up. No cross-sectional associations were found between cluster membership, and BMI z-score or weight status at baseline. Longitudinally, children in the 'ED consumers who watch TV' cluster had a higher odds of being overweight/obese at follow-up (OR=2.8; 95% CI: 1.1, 6.9; P<0.05). Tracking of cluster membership was fair to moderate in younger (K=0.24; P=0.0001) and older children (K=0.46; P<0.0001). CONCLUSIONS: This study identified an unhealthy cluster of TV viewing with ED food/drink consumption which predicted overweight/obesity in a small longitudinal sample of Australian children. Cluster stability was fair to moderate over three years and is a novel finding. Prospective research in larger samples is needed to examine how obesity-related clusters track over time and influence the development of overweight and obesity.International Journal of Obesity accepted article preview online, 24 April 2015. doi:10.1038/ijo.2015.66.

FEACS: a flexible and efficient access control scheme for cloud computing

In the past few years, cloud computing has emerged as one of the most influential paradigms in the IT industry. As promising as it is, this paradigm brings forth many new challenges for data security because users have to outsource sensitive data on untrusted cloud servers for sharing. In this paper, to guarantee the confidentiality and security of data sharing in cloud environment, we propose a Flexible and Efficient Access Control Scheme (FEACS) based on Attribute-Based Encryption, which is suitable for fine-grained access control. Compared with existing state-of-the-art schemes, FEACS is more practical by following functions. First of all, considering the factor that the user membership may change frequently in cloud environment, FEACS has the capability of coping with dynamic membership efficiently. Secondly, full logic expression is supported to make the access policy described accurately and efficiently. Besides, we prove in the standard model that FEACS is secure based on the Decisional Bilinear Diffie-Hellman assumption. To evaluate the practicality of FEACS, we provide a detailed theoretical performance analysis and a simulation comparison with existing schemes. Both the theoretical analysis and the experimental results prove that our scheme is efficient and effective for cloud environment.

Typology of alcohol mixed with energy drink consumers: motivations for use

Background: Previous research on alcohol mixed with energy drinks (AmED) has shown that use is typically driven by hedonistic, social, functional, and intoxication-related motives, with differential associations with alcohol-related harm across these constructs. There has been no research looking at whether there are subgroups of consumers based on patterns of motivations. Consequently, the aims were to determine the typology of motivations for AmED use among a community sample and to identify correlates of subgroup membership. In addition, we aimed to determine whether this structure of motivations applied to a university student sample. Methods: Data were used from an Australian community sample (n = 731) and an Australian university student sample (n = 594) who were identified as AmED consumers when completing an online survey about their alcohol and ED use. Participants reported their level of agreement with 14 motivations for AmED use; latent classes of AmED consumers were identified based on patterns of motivation endorsement using latent class analysis. Results: A 4-class model was selected using data from the community sample: (i) taste consumers (31%): endorsed pleasurable taste; (ii) energy-seeking consumers (24%): endorsed functional and taste motives; (iii) hedonistic consumers (33%): endorse pleasure and sensation-seeking motives, as well as functional and taste motives; and (iv) intoxication-related consumers (12%): endorsed motives related to feeling in control of intoxication, as well as hedonistic, functional, and taste motives. The consumer subgroups typically did not differ on demographics, other drug use, alcohol and ED use, and AmED risk taking. The patterns of motivations for the 4-class model were similar for the university student sample. Conclusions: This study indicated the existence of 4 subgroups of AmED consumers based on their patterns of motivations for AmED use consistently structured across the community and university student sample. These findings lend support to the growing conceptualization of AmED consumers as a heterogeneous group in regard to motivations for use, with a hierarchical and cumulative class order in regard to the number of types of motivation for AmED use. Prospective research may endeavor to link session-specific motives and outcomes, as it is apparent that primary consumption motives may be fluid between sessions.

Neighbourhood environment, sitting time and motorised transport in older adults: a cross-sectional study in Hong Kong

OBJECTIVES: Sitting time is a public health concern. This study examined associations of objectively measured neighbourhood environmental attributes with non-transport sitting time and motorised transport in 484 Hong Kong older adults. Neighbourhood attributes encouraging walking may help older adults replace some sitting time at home and on motorised transport with light-to-moderate-intensity activities such as strolling around the neighbourhood or walking to/from neighbourhood destinations. Thus, we hypothesised environmental attributes found to be related to walking would show associations with non-transport sitting time and motorised transport opposite to those seen for walking. DESIGN: Cross-sectional. SETTING: Hong Kong, an ultradense urban environment. PARTICIPANTS: 484 ethnic Chinese Hong Kong residents aged 65+ recruited from membership lists of four Hong Kong Elderly Health Centres representing catchment areas of low and high transport-related walkability stratified by socioeconomic status (response rate: 78%). PRIMARY AND SECONDARY OUTCOME MEASURES: Attributes of participants' neighbourhood environments were assessed by environmental audits, while non-transport sitting time and motorised transport were ascertained using the International Physical Activity Questionnaire-Long Form (Chinese version). RESULTS: Daily non-transport sitting minutes were 283 (SD=128) and motorised transport 23 (SD=28). Prevalence of signs of crime/disorder, streetlights, public facilities (toilets and benches) and pedestrian safety were independently negatively related, and sloping streets positively related, to sitting outcomes. Places of worship in the neighbourhood were predictive of more, and prevalence of public transit points of less, non-transport sitting. Associations of either or both sitting outcomes with prevalence of food/grocery stores and presence of parks were moderated by path obstructions and signs of crime/disorder. CONCLUSIONS: The findings suggest that access to specific destinations and relatively low-cost, minimal impact modifications to the urban form, such as street lighting, public toilets, benches and public transit points, could potentially reduce sitting time and associated negative health outcomes in Hong Kong older adults.

Family control and corporate cash holdings: Evidence from China

This study examines the effect of family control on the cash holding policy in China. We find that family firms with excess control rights tend to have high cash holdings that are tunneled rather than being invested or paid to shareholders. We further show that the incentive for controlling families to hold cash and for tunneling is exacerbated by the agency conflict between controlling and minority shareholders, i.e., it is weakened after the Chinese Non-tradable share (NTS) reform and strengthened by the presence of multiple large shareholders who probably play no monitoring role in Chinese family firms. Furthermore, family firms’ incentive to hold cash for tunneling is influenced by the unique characteristics of Chinese firms in the following ways: the incentive is stronger when the family founder has one child and face family succession problem, and when the founder has political connections and directly involves in firm’s management; while it is weakened by family founder’s social interpersonal trust with other entrepreneurs through their membership of Chambers of Commerce. Overall, we argue that family firms in China tend to hold high levels of cash for tunneling, which harms firm value, while the severe controlling-minority shareholder agency conflicts and unique Chinese family characteristics only make this situation worse.

Changing social norms and CEO pay: the role of norms entrepreneurs

This is the third in a series of papers examining different aspects of the CEO compensation debate. This Article will explore attempts by norms entrepreneurs to create or modify social norms. It argues that the relevant social norms are in a state of flux because of the work of norms entrepreneurs, whose efforts might reduce the need for legislative intervention. Several new norms like majority voting for board election, say on pay, smaller multiples for severance packages, and respect for shareholder activists may be emerging due to the work of norms entrepreneurs. Part II analyzes the rich literature on social norms to determine if there are models capable of application to better correlate executive compensation with performance. Despite several problems at the definitional level, it argues that the actions of constituencies relevant to the CEO pay debate might be explained by signaling, esteem, and expressive theories. Further, social norms theories neglecting internalization are deficient; corporate actors undertake self-improvement only when they internalize norms. Part III identifies the work of norms entrepreneurs in creating or changing norms pertaining to CEO compensation, and analyzes the reasons for their success. The examples considered demonstrate the effects of dynamic normative transformations on corporate actors and illustrate the contrast in behavioral changes accompanying resistance and acceptance of new norms. Part IV concludes that norm creation in corporate law is facilitated by the role of groups where membership benefits are dependent on reputation; that directors cannot tradeoff reputation like CEOs, making the deployment of reputational sanctions against them powerful; that behavioral change is more effective when there is norm internalization; and that norms entrepreneurs ought to focus on socializing relevant actors if they aspire to be successful in achieving normative change.

Young people's perceptions of the risks of methamphetamine use in Adelaide nightclubs: a quantitative study

Understanding young people’s perceptions of the risks associated with the use of methamphetamines is an important but under-researched area. Precisely how these young people use the space of Adelaide nightclubs, perceive such drug risks, employ risk management strategies and how these factors interact to influence their experience of methamphetamines in the nightclub is largely unknown. This article presents self-report data drawn from a sample of 457 young people who completed the Perception of Risk survey questionnaire while waiting to enter one of five key Adelaide nightclubs in 2010. Participants were examined in terms of gender, age, drug use history, motivations for nightclub attendance and frequency of nightclub attendance. Approximately one-fifth of the sample reported using methamphetamines (21.0 percent).Participants demonstrated a pattern of attendance at Adelaide nightclubs that reflects a broader understanding of the important role of the nightclub in their social lives, which for some also involves the use of methamphetamines. Specifically, participants’ motivations for ‘nightclubbing’ concern the consumption of leisure and are guided by social group membership, in which methamphetamine use is not prioritised, as evident in the development of knowledge and risk management strategies to ensure safe consumption in the club. Perceptions of risk reflect concern surrounding unregulated methamphetamine use, as well as gendered concerns linked to safety and the prevalence of alcohol misuse, violence, drink spiking, physical injury and sexual assault. These findings were consistent across the sample, suggesting a shift in youth nightclub culture that has numerous implications for understanding and reducing the use of methamphetamines and regulation of the night-time economy generally, which are discussed herein.

Maternal prenatal mental health and placental 11β-HSD2 gene expression: initial findings from the mercy pregnancy and emotional wellbeing study

High intrauterine cortisol exposure can inhibit fetal growth and have programming effects for the child's subsequent stress reactivity. Placental 11beta-hydroxysteroid dehydrogenase (11β-HSD2) limits the amount of maternal cortisol transferred to the fetus. However, the relationship between maternal psychopathology and 11β-HSD2 remains poorly defined. This study examined the effect of maternal depressive disorder, antidepressant use and symptoms of depression and anxiety in pregnancy on placental 11β-HSD2 gene (HSD11B2) expression. Drawing on data from the Mercy Pregnancy and Emotional Wellbeing Study, placental HSD11B2 expression was compared among 33 pregnant women, who were selected based on membership of three groups; depressed (untreated), taking antidepressants and controls. Furthermore, associations between placental HSD11B2 and scores on the State-Trait Anxiety Inventory (STAI) and Edinburgh Postnatal Depression Scale (EPDS) during 12-18 and 28-34 weeks gestation were examined. Findings revealed negative correlations between HSD11B2 and both the EPDS and STAI (r = -0.11 to -0.28), with associations being particularly prominent during late gestation. Depressed and antidepressant exposed groups also displayed markedly lower placental HSD11B2 expression levels than controls. These findings suggest that maternal depression and anxiety may impact on fetal programming by down-regulating HSD11B2, and antidepressant treatment alone is unlikely to protect against this effect.

The relative importance of spatial proximity, kin selection and potential ‘greenbeard’ signals on provisioning behaviour among helpers in a cooperative bird

© 2015 Springer-Verlag Berlin Heidelberg Many hypotheses have been proposed to account for cooperative behaviour, with those favouring kin selection receiving the greatest support to date. However, the importance of relatedness becomes less clear in complex societies where interactions can involve both kin and non-kin. To help clarify this, we examined the relative effect of indirect versus key direct benefit hypotheses in shaping cooperative decisions. We assessed the relative importance of likely reciprocal aid (as measured by spatial proximity between participants), kin selection (using molecular-based relatedness indices) and putative signals of relatedness (vocal similarity) on helper/helper cooperative provisioning dynamics in bell miners (Manorina melanophrys), a species living in large, complex societies. Using network analysis, we quantified the extent of shared provisioning (helping at the same nests) among individual helpers (excluding breeding pairs) over three seasons and 4290 provisioning visits, and compared these with the location of individuals within a colony and networks built using either genetic molecular relatedness or call similarity indices. Significant levels of clustering were observed in networks; individuals within a cluster were more closely related to each other than other colony members, and cluster membership was stable across years. The probability of a miner helping at another’s nest was not simply a product of spatial proximity and thus the potential for reciprocal aid. Networks constructed using helping data were significantly correlated to those built using molecular data in 5 of 10 comparisons, compared to 8 of 10 comparisons for networks constructed using call similarity. This suggests an important role of kinship in shaping helping dynamics in a complex cooperative society, apparently determined via an acoustic ‘greenbeard’ signal in this system.
