Commonising the enclosure : online games and reforming intellectual property regimes

Online computer gamers are a creative bunch, from the mayhem of first-person shooters (FPS) to the more social experiences of massive multiplayer online role-playing games (MMORPG), gamers are producing new content for their favourite titles at an amazing rate. This paper explores the rewriting of the boundaries in the production and ownership of intellectual property in the computer games industry. The purpose is to examine the potential for computer game studies to contribute to an understanding of an alternative intellectual property regime known as the commons. This paper will explore how computer games users establish commons-like formations, specific to the digital environment, that extend the confines of current intellectual property rights. It will argue that the productive activities of online gamers are not motivated by the traditional logic of market-based incentives. This represents a new condition which may contribute to a reformation of the privatising enclosure of the intellectual property system.

Adolescent victims with an intellectual disability : perceived credibility in cases of sexual abuse

The study aimed to assess perceptions of the credibility of adolescent victims with intellectual disability. Results revealed that victim and participant characteristics influenced perceptions of the credibility of the victim and verdict responses. Findings related to the level of ID, type of offence, perceptions of competency, honesty, suggestibility, and gender of victim and participant.

Positioning people with intellectual disabilities as the experts : enhancing pre-service teachers’ competencies in teaching for diversity

The need for graduate teachers to own their professional responsibilities to engage successfully with students with special educational needs (SENs) in mainstream classrooms has been recognised in educational policies and programmes in many countries for well over two decades. Despite wide-ranging research, questions remain as to how pre-service education courses can help beginning teachers to develop the required commitment, knowledge and pedagogies to feel confident in teaching students with disabilities. Challenges to find new ways to enhance pre-service teachers’ familiarity with special needs children, overcome resistance from some towards including SEN students in mainstream classrooms and develop a sense of efficacy in teaching are common to many programmes. In this paper, we report on a pilot study where adults with intellectual disabilities, as members of a community theatre, were positioned as the experts and explored their schooling experiences and personal biographies with soon-to-be graduate teachers in a 3 h workshop. Taking the lead and working collaboratively with the workshop participants, members of Fusion Theatre used drama activities to develop understandings of strategies that helped them to learn. By challenging the traditional power relationships between those labelled as ‘disabled’ and those who would be teachers, the workshop helped the participants to engage on many levels. Here, we report on the data, analyse the findings and discuss implications for other pre-service programmes.

Conditionally sexual : men and teenage boys with moderate to profound intellectual disability

This article presents qualitative research data about the sexuality of men and teenage boys with moderate to profound intellectual disability. Research findings pointed to a conditional construct of sexuality based within a biopsychosocial framework. The notion Conditionally Sexual represents the perceived limitations, within a rights-based discourse, of these men and teenage boys’ sexuality. The limitations to person-centred service delivery from a policy vacuum in the area of sexuality and intellectual disability represents a major challenge for paid staff. We suggest that a move toward better understanding how to support such a conditional sexual construct will assist the development of a healthy masculine sexuality for men and boys with intellectual disability.

The impression that I get : educational inclusion explored through the voices of young people with vision impairment

Despite the notion of educational inclusion of students with disabilities increasing in popularity, the day-to-day reality of its effectiveness remains mostly unknown. This paper reports key findings of a small-scale qualitative study that was conducted with a group of young people with vision impairment who attended an inclusive secondary school. The aim of the research was to ascertain their voiced experiences of their inclusion. Relevant to the study was the researcher’s insider status, which allowed for his unique insight and shared experiences with participants to influence data collection and analysis. The students reported a constant trade off that occurred between their aspirations for access and autonomy and practices of other stakeholders in the school that both facilitated and inhibited their inclusion. In sum, the students’ inclusion was ineffective because of habitual inhibiting actions of others. Recommendations are made based on Slee’s (2001) call for altered teaching and learning realities to promote educational inclusion, and a model of social justice that could bring about increased student agency (Higgins, Macarthur & Kelly, 2009).

The cost-effectiveness of universal newborn screening for bilateral permanent congenital hearing impairment : systematic review

Objective - Universal newborn hearing screening for bilateral permanent congenital hearing impairment is standard practice in many developed economies, but until there is clear evidence of cost-effectiveness, it remains a controversial use of limited health care resources. We conducted a formal systematic review of studies of newborn hearing screening that considered both costs and outcomes to produce a summary of the available evidence and to determine whether there was a need for further research.

Methods - A search was conducted of medical and nursing databases and gray literature websites by the use of multiple keywords. The titles and abstracts of studies were examined for preliminary inclusion if reference was made to newborn hearing screening, and to both costs and outcomes. Studies of potential relevance were independently assessed by 2 health economists for final inclusion in the review. Studies that met inclusion criteria were appraised by the use of existing guidelines for observational studies, economic evaluations and decision analytic models, and reported in a narrative literature review.

Results - There were 22 distinct observational or modeled evaluations of which only 2 clearly compared universal newborn hearing screening to risk factor screening for bilateral permanent congenital hearing impairment. Of these, the single evaluation that examined long-term costs and outcomes found that universal newborn hearing screening could be cost-saving if early intervention led to a substantial reduction in future treatment costs and productivity losses.

Conclusions - There are only a small number of economic evaluations that have examined the long-term cost-effectiveness of universal newborn hearing screening. This is partly attributable to ongoing uncertainty about the benefits gained from the early detection and treatment of bilateral permanent congenital hearing impairment. There is a clear need for further research on long-term costs and outcomes to establish the cost-effectiveness of universal newborn hearing screening in relation to other approaches to screening, and to establish whether it is a good long term investment.

The content validity of the behaviour support plan quality evaluation tool (BSP-QEII) and its potential application in accommodation and day-support services for adults with intellectual disability

Background The quality of support provided to people with disability who show challenging behaviour could be influenced by the quality of the behaviour support plans (BSPs) on which staff rely for direction. This study investigated the content validity of the Behaviour Support Plan Quality Evaluation tool (BSP-QEII), originally developed to guide the development of BSPs for children in school settings, and evaluated its application for use in accommodation and day-support services for adults with intellectual disability.

Method A three-round Delphi study involving a purposive sample of experienced behaviour support practitioners (n = 30) was conducted over an 8-week period. The analyses included deductive content analysis and descriptive statistics.

Results The 12 quality domains of the BSP-QEII were affirmed as valid for application in adult accommodation and day-support service settings. Two additional quality domains were suggested, relating to the provision of detailed background on the client and the need for plans to reflect contemporary service philosophy. Furthermore, the results suggest that some issues previously identified in the literature as being important for inclusion in BSPs might not currently be a priority for practitioners. These included: the importance of specifying replacement or alternative behaviours to be taught, descriptions of teaching strategies to be used, reinforcers, and the specification of objective goals against which to evaluate the success of the intervention programme.

Conclusions The BSP-QEII provides a potentially useful framework to guide and evaluate the development of BSPs in services for adults with intellectual disability. Further research is warranted to investigate why practitioners are potentially giving greater attention to some areas of intervention practice than others, even where research has demonstrated these others areas of practice could be important to achieving quality outcomes.

Fructose-1,6-Bisphosphatase overexpression in pancreatic [beta]-cells results in reduced insulin secretion : a new mechanism for fat-induced impairment of [beta]-cell function

Fructose-1,6-bisphosphatase (FBPase) is a gluconeogenic enzyme that is upregulated in islets or pancreatic beta-cell lines exposed to high fat. However, whether specific beta-cell upregulation of FBPase can impair insulin secretory function is not known. The objective of this study therefore is to determine whether a specific increase in islet beta-cell FBPase can result in reduced glucose-mediated insulin secretion.

To test this hypothesis, we have generated three transgenic mouse lines overexpressing the human FBPase (huFBPase) gene specifically in pancreatic islet beta-cells. In addition, to investigate the biochemical mechanism by which elevated FBPase affects insulin secretion, we made two pancreatic beta-cell lines (MIN6) stably overexpressing huFBPase.

FBPase transgenic mice showed reduced insulin secretion in response to an intravenous glucose bolus. Compared with the untransfected parental MIN6, FBPase-overexpressing cells showed a decreased cell proliferation rate and significantly depressed glucose-induced insulin secretion. These defects were associated with a decrease in the rate of glucose utilization, resulting in reduced cellular ATP levels.

Taken together, these results suggest that upregulation of FBPase in pancreatic islet beta-cells, as occurs in states of lipid oversupply and type 2 diabetes, contributes to insulin secretory dysfunction.

High glucose-induced impairment in insulin secretion is associated with reduction in islet glucokinase in a mouse model of susceptibility to islet dysfunction

Type 2 diabetes is characterized by islet dysfunction resulting in hyperglycemia, which can then lead to further deterioration in islet function. A possible mechanism for hyperglycemia-induced islet dysfunction is the accumulation of advanced glycation end products (AGE). The DBA/2 mouse develops pancreatic islet dysfunction when exposed to a high glucose environment and/or obesity-induced insulin resistance. To determine the biochemical cause of dysfunction, DBA/2 and C57BL/6 control islets were incubated in 11.1 mM or 40 mM glucose in the absence or presence of the AGE inhibitor aminoguanidine (AG) for 10 days. Basal (2.8 mM glucose) insulin release was increased in both DBA/2 and C57BL/6 islets incubated with 40 mM vs 11.1 mM glucose for 10 days. Chronic exposure to hyperglycemia decreased glucose (20 mM)-stimulated insulin secretion in DBA/2 but not in C57BL/6 islets. AG significantly increased fold-induced insulin release in high glucose cultured DBA/2 mouse islets, but did not affect C57BL/6 islet function. DBA/2 islet glucokinase was significantly reduced following 40 mM glucose culture, compared with 11.1 mM glucose cultured DBA/2 islets and 40 mM glucose cultured C57BL/6 islets. Incubation of islets with AG resulted in a normalization of DBA/2 islet glucokinase levels. In conclusion, chronic high glucose-induced increases in AGE can result in islet dysfunction and this is associated with reduced glucokinase levels in a mouse model with susceptibility to islet failure.

Total antioxidant status correlates with cognitive impairment in patients with recurrent depressive disorder

Depressive disorder is a multifactorial diseases, that one of the typical feature are cognitive impairments. The aim of this study was to determine the total antioxidant status (TAS) in patients with recurrent depressive disorder (rDD) and to define relationship between plasma levels of TAS and the cognitive performance. Design and methods: the study comprised 74 subjects: patients with rDD (n = 45) and healthy subjects (n = 29). Cognitive function assessment was based on: Trail Making Test, The Stroop Test, Verbal Fluency Test and Auditory Verbal Learning Test. Statistically significant differences were found in the intensity of depression symptoms, measured by the Hamilton Depression Rating Scale (HDRS) on therapy onset versus the examination results after 8 weeks of treatment (p < 0.001). The level of TAS was substantially higher in patients with rDD (p = 0.01). For rDD patients, elevated TAS levels were associated with worse cognitive test performance. The higher was the concentration of plasma TAS, the greater was the severity of depressive symptoms measured by HDRS before and after pharmacotherapy. (1) Higher concentration of plasma TAS in rDD patients is associated with the severity of depressive symptoms. (2) Elevated levels of plasma TAS are related to impairment of short-term declarative memory, long-term declarative-memory, verbal fluency and working memory.
