Parental self-confidence, parenting styles, and corporal punishment in families of ADHD children in Iran

OBJECTIVE: This study examines the relationship between parental self-confidence, warmth, and involvement, and corporal punishment in families of children with attention deficit/hyperactivity disorder (ADHD). METHOD: The diagnosis of ADHD was established through clinical interviews with the parents, children, and teachers, according the criteria in DSM-IV-TR. This diagnosis was also established by having the parents complete the Conners' Parent Rating Scale, and the teachers complete the Conners' Teacher Rating Scale. Two groups of Iranian parents, one group with children who have ADHD (N=130) and a control group (N=120), completed questionnaires measuring parental self-confidence and parenting styles. RESULTS: Parents of children with ADHD were found to have lower self-confidence and less warmth and involvement with their children, and used corporal punishment significantly more than the parents of control children. CONCLUSIONS: The study provides strong evidence that children with ADHD are at considerable risk of abuse by their parents. Rather than focusing only on the child's ADHD, treatment may also need to address the parents' functioning.     

Mycorrhizoremediation an enhanced form of phytoremediation

Study of plant roots and the diversity of soil micro biota, such as bacteria, fungi and microfauna associated with them, is important for understanding the ecological complexities between diverse plants, microbes, soil and climates and their role in phytoremediation of contaminated soils. The arbuscular mycorrhizal fungi （AMF） are universal and ubiquitous rhizosphere mi- croflora forming symbiosis with plant roots and acting as biofertilizers, bioprotactants, and biodegraders. In addition to AMF, soils also contain various antagonistic and beneficial bacteria such as root pathogens, plant growth promoting rhizobacteria including free-living and symbiotic N-fixers, and mycorrhiza helping bacteria. Their potential role in phytoremediation of heavy metal （HM） contaminated soils and water is becoming evident although there is need to completely understand the ecological complexities of the plant-microbe-soil interactions and their better exploitation as consortia in remediation strategies employed for contaminated soils. These multitrophic root microbial associations deserve multi-disciplinary investigations using molecular, biochemical, and physiological techniques. Ecosystem restoration of heavy metal contaminated soils practices need to incorporate microbial biotechnology research and development. This review highlights the ecological complexity and diversity of plant-microbe-soil combinations, particularly AM and provides an overview on the recent developments in this area. It also discusses the role AMF play in phytorestoration of HM contaminated soils, i.e. mycorrhizoremediation.     

A “research” into international student-related research: (Re)Visualising our stand?

This paper uses Tight (High Educ Res Dev 23(4):395–411, 2004; High Educ Res Dev 31(5):723–740, 2012; High Educ Res Dev 32(1):136–151, 2013)’s journal analysis and review framework to review a sample of 497 journal articles on researches concerning international students over the past 30 years. It was found that a majority of the articles focus on the students’ in-campus, academic and social experience. Even with different conceptualisation of the terms “international student” and “international student mobility”, international students undergo similar challenges throughout their sojourn duration, and much of the responsibilities in managing international students fall on universities and respective faculty members within the institutions. It might seem as if we are going in circles in terms of the issues and concerns in managing international students, but the silver lining out of this observation is the increased ethnical awareness among countries and higher education institutions in hosting and safeguarding the students throughout their international higher education experience, albeit rather slowly. The analysis brings to attention how much have we achieved in internationalisation of higher education in general and international student-related research in particular, and the potential for greater expansion and focus on managing the student population within a comprehensive “life cycle” approach.     

Older Women and Lower Self-Rated Health

Several studies have found that older women report lower self-rated health than men. However, it is not clear why older women are more likely to report poor self-rated health than older men. Data for this study came from a national cross-sectional survey, Mental Health and Quality of Life of Older Malaysians (MHQoLOM). Included in the survey were 2980 respondents consisting of Malaysians aged 60 years and over, with both men (n = 1428) and women (n = 1552) represented. Results of t-tests showed older men expressed significantly higher levels of self-rated health and self-esteem than women (p < .01). Separate multivariate regression by gender revealed that age, life-threatening problems, and self-esteem were highly significant predictors of self-rated health among older men and women and explained 18.4% of variance in self-rated health for men and 18.2% for women. In the last step we examined the main effects of gender on self-rated health using General Linear Models (GLM) Univariate by adjusting for age, life-threatening problems, and self-esteem. Results showed an insignificant difference in self-rated health between older men and women (F _(1,2715) = 2.26, P = 0.13) only after adjusting for self-esteem. It can be concluded that self-esteem affects responses to self-rated health of older men and women.     

Consumerisation in UK higher education business schools: higher fees,greater stress and debatable outcomes

For many UK higher education business schools, the continued recruitment of UK, EU and international students is crucial for financial stability, viability and independence. Due to increasingly competitive funding models across the sector, many institutional leaders and administrators are making decisions typical of highly marketised consumer environments. Thus, this paper explores academics’ perceptions of the impact of consumerisation in UK higher education business schools. To achieve this, 22 business school academics were interviewed within three UK higher education institutions (HEIs) in the North of England. Participants had a minimum of three years teaching experience. Data was analysed using template analysis taking an interpretive approach. The findings indicate that academics perceived the introduction of tuition fees to have been the catalyst for students increasing demonstration of customer-like behaviour: viewing the education process as transactional, with the HEI providing a ‘paid for’ service. It is argued that these changes in UK higher education have created tensions between university leaders and academics, creating genuine dilemmas for those with decision-making responsibilities who must balance academic integrity and long-term institutional financial viability.     

Network Organizations: Symmetric Cooperation or Multivalent Negotiation?

The network model of organization plays a central role in recent sociological accounts of the information economy. This model is also often presented in organization and information and communication technologies (ICT) literature with an air of enthusiasm that underscores its advantages—flexibility, cooperative culture, innovativeness, and knowledge and technology intensity. Such themes are usually based on a “networking logic” that assumes the trustful cooperation of large and small production firms in a rapidly changing economic environment. We believe that both the logic and the themes based upon it are too narrow to be able to explain the complex dimensions of interorganizational networking. Using Enron as a case study, our goal in this article is to enrich the logic just described and to develop an extended model of the network enterprise. We argue that this is only possible by extending the unit of analysis beyond the production firm, to include, among others, subsidiaries, banks, investors, auditors, and government agencies. The proposed extended model allows the broadening of many of the aforementioned themes, making it possible to arrive at a realistic picture of the complexities of the network enterprise. The managerial advantages of the model are also discussed.     

Child maltreatment among school children in the Kurdistan Province, Iran

OBJECTIVE: This study examines the determinants of three types of child maltreatment: physical maltreatment, mental maltreatment, and child neglect among school children in the Kurdistan Province of Iran. The analysis examines the impact of socioeconomic, familial, demographic, and household dynamic factors on the three child maltreatment outcomes, and compares the differential impact of these factors across the three types of child maltreatment. A greater understanding of the factors associated with child maltreatment has the potential to inform public health interventions aimed at reducing specific forms of maltreatment and at identifying at risk populations. METHODS: Data were collected from 1,370 school students, age 11-18. Separate logistic models are fitted for six binary outcomes examining self-reported experiences of physical maltreatment in the home or school, mental maltreatment in the home or school, and child neglect in the home or school. RESULTS: Male children were more likely to report experiencing any kind of child maltreatment than girls. Residency in a rural area, poor parental relationships and the use of addictive substances by household members were associated with increased odds of reporting child maltreatment. Poor school performance was associated with the reporting of experiencing maltreatment at school. CONCLUSION: Each of the forms of child maltreatment is highly correlated with socioeconomic, demographic, and living condition factors. The results point to the strong influence that familial factors have in shaping a child's likelihood of reporting maltreatment. Characteristics of the mother were associated with maltreatment, but not characteristics of the father. The results highlight a number of mechanisms through which public health interventions may seek to reduce the prevalence of child maltreatment in Kurdistan; different approaches are needed to reduce child maltreatment in the home and school environments.     

Application of automated image analysis to the identification and extraction of recyclable plastic bottles

An experimental machine vision apparatus was used to identify and extract recyclable plastic bottles out of a conveyor belt. Color images were taken with a commercially available Webcam, and the recognition was performed by our homemade software, based on the shape and dimensions of object images. The software was able to manage multiple bottles in a single image and was additionally extended to cases involving touching bottles. The identification was fulfilled by comparing the set of measured features with an existing database and meanwhile integrating various recognition techniques such as minimum distance in the feature space, self-organized maps, and neural networks. The recognition system was tested on a set of 50 different bottles and provided so far an accuracy of about 97% on bottle identification. The extraction of the bottles was performed by means of a pneumatic arm, which was activated according to the plastic type; polyethylene-terephthalate （PET） bottles were left on the conveyor belt, while non-PET bottles were extracted. The software was designed to provide the best compromise between reliability and speed for real-time applications in view of the commercialization of the system at existing recycling plants.
