Knowledge sharing in open source software project teams: A transactive memory system perspective

The extant studies have not empirically examined the possible team cognitive mechanisms that facilitate knowledge sharing in OSS teams, even though knowledge sharing is a cognitive task and an OSS team is a complex cognitive system. To fill this research gap, we adopt the perspective of transactive memory system (TMS) to explore the relationships among TMS, knowledge sharing, communication quality, and technical achievement of OSS teams. By analyzing data from 95 OSS projects with the partial least squares (PLS) method, our study demonstrates that several TMS dimensions have positive impacts on knowledge sharing behaviors and communication quality. Moreover, communication quality positively influences technical achievement of OSS teams. These findings provide useful implications for literature and practice.

Is reported childhood sexual abuse associated with the psychopathological characteristics of patients who experience auditory hallucinations?

OBJECTIVE: The aim of this study was to determine whether reported childhood sexual abuse is related to the severity of symptoms in patients who experience auditory hallucinations. METHOD: A sample of 26 adult male and females with psychotic disorders involving auditory hallucinations were interviewed and were asked to complete three self-report measures: the Dissociative Experiences Scale (DES-II and DES-taxon versions); the Beck Depression Inventory (BDI); and the Beliefs About Voices Questionnaire (BAVQ). They were also asked about any history of sexual abuse in childhood. RESULTS: A history of childhood sexual abuse was reported by 10 of the 26 patients (38.5%), and was associated with higher levels of depression and dissociation, as well as being linked to a tendency to regard the voices as more malevolent. The same three features were all associated with the age at first reported abuse, with a younger age of first experience being related to higher levels of psychopathology in all instances. CONCLUSIONS: These results require replication and refinement in future research, but indicate a need for greater attention to be paid to the possible role of childhood sexual abuse when understanding and treating auditory hallucinations.     

Anogenital warts in childhood

Fifteen children with anogenital warts are presented. Twelve cases were referred for assessment of sexual abuse which was established in six cases, strongly suspected in one, and excluded in three. In two, the source was unclear. Papillomavirus typing was carried out by HPV DNA dot and Southern blot hybridization using mixed HPV 6/11, 16/18, and 2/3 DNA probes on 15 specimens from 12 of the children. Seven biopsy specimens were positive for HPV 6 or 11 and one hybridized with both HPV 6/11 and 16/18 mixed sets of probes. Two specimens were positive for HPV 2, and a further two hybridized with both HPV 18 and 2. Three wart specimens could not be typed with the available genital or skin probes. The viruses causing genital tract papillomata are the same for children and adults. The identification of HPV 16/18 raises the concern of potential oncogenicity and stresses the need for long-term assessment. The diagnosis of sexual abuse was made on history rather than examination, as only two cases showed additional physical signs of sexual abuse. It is advocated that the presence of anogenital warts alone be sufficient grounds to pursue the possibility of sexual abuse. Nonsexual transmission, although possible, is far less likely.     

Perceptions of optimal conditions for teaching and learning: a case study from Flinders University

Effective teaching and learning in higher education is an important focal point of literature around the globe. Various models are presented as desirable and fostering optimal conditions for teaching and learning. However, each model must be examined within the context of its institutional culture, mission and strategic plan to ascertain if it meets the envisaged goals. The Reinventing Teaching Project survey conducted at Flinders University in 2009 provided a unique opportunity for academic staff and students across all faculties to respond to a survey that explored their perceptions of optimal learning conditions and assessed if the campus environment was conducive to effective teaching and learning practices. The exploratory study was designed to gather qualitative and quantitative data on the motivation of teachers and learners to engage with learning and learners (or not). The results of the survey present valuable insights into what teachers and learners consider to be important attributes of optimal teaching and learning and indicate a number of similarities and differences among teacher-student perceptions. This paper identifies and discusses some of the pertinent outcomes of the study to provide a framework for other similar studies.     

Relations among home literacy environment,child characteristics and print knowledge for preschool children with language impairment

To contribute to the modest body of work examining the home literacy environment (HLE) and emergent literacy outcomes for children with disabilities, this study addressed two aims: (a) to determine the unique contributions of the HLE on print knowledge of preschool children with language impairment and (b) to identify whether specific child characteristics (oral language ability, print interest) moderated these relations. The sample consisted of 119 preschool children with language impairment. HLE was conceptualised as frequency of storybook reading and literacy teaching during book reading. Frequency of storybook reading was a unique predictor of print knowledge, which is consistent with research on children with typical language. Literacy teaching did not predict print knowledge, which diverges from research on children with typical language. No interactions between the HLE and child characteristics were significant, but language ability and print interest play a role in understanding individual differences in literacy development.
