Boarding schools: A longitudinal examination of Australian Indigenous and non-Indigenous boarders’ and non-boarders’ wellbeing

Improving educational outcomes for Indigenous Australian students is a key strategy to helping Indigenous people reach their full potential. This has resulted in well-intentioned efforts by Australian educators and governments to ensure Indigenous children have positive school experiences. However, Indigenous students still lag behind their non-Indigenous counterparts in educational outcomes. This is particularly so for Indigenous students living in rural and remote parts of Australia where educational opportunities are limited, especially in high school. One solution to this problem has been to enrol these students in boarding schools in urban and metropolitan centres. While research on the success of boarding schools for Indigenous students is scarce, what little that does exist is not encouraging. The focus of this research was to examine the effects of boarding for Indigenous (n = 11) and non-Indigenous students’ (n = 158) wellbeing (N = 1423) in two large private boys’ schools. Participating students aged 12–18 years old completed a survey measuring wellbeing constructs on two occasions, 12 months apart. Non-Indigenous boys were generally higher in wellbeing compared with Indigenous boys. There was also evidence of improved social wellbeing beyond that of non-Indigenous boarders over time. Overall, while evidence of merit was weak, boarding schools may benefit their Indigenous students’ development in social wellbeing.     

Teaching Criminal Justice Online: Current Status and Important Considerations

The most significant change to impact the pedagogy of criminal justice students in recent years has been the development of online classes. Online coursework is now a commonly accepted method of accessing criminal justice students and the sustained growth in online classes is expected to continue in the future. However, there is currently a lack of research that focuses on online classes in criminal justice. In response, we present and assess the modest literature regarding criminal justice online classes and highlight important themes. This leads into a presentation of important considerations along the following pedagogical continuum: Planning the online course (i.e. asynchronous timing, technological developments), implementing the online course (i.e. maintaining an online presence, managing student interactions and expectations), and identifying effective means to measure learning outcomes (i.e. measuring success, quality matters). Policy implications for online coursework that are likely to impact future criminal justice educational practices are then discussed.     

Query expansion with terms selected using lexical cohesion analysis of documents

We present new methods of query expansion using terms that form lexical cohesive links between the contexts of distinct query terms in documents (i.e., words surrounding the query terms in text). The link-forming terms (link-terms) and short snippets of text surrounding them are evaluated in both interactive and automatic query expansion (QE). We explore the effectiveness of snippets in providing context in interactive query expansion, compare query expansion from snippets vs. whole documents, and query expansion following snippet selection vs. full document relevance judgements. The evaluation, conducted on the HARD track data of TREC 2005, suggests that there are considerable advantages in using link-terms and their surrounding short text snippets in QE compared to terms selected from full-texts of documents.     

Emotion recognition in fathers and mothers at high-risk for child physical abuse

Objective

The present study was designed to determine whether parents at high risk for physical child abuse, in comparison with parents at low risk, show deficits in emotion recognition, as well as to examine the moderator effect of gender and stress on the relationship between risk for physical child abuse and emotion recognition.

Methods

Based on their scores on the Abuse Scale of the CAP Inventory (Milner, 1986), 64 parents at high risk (24 fathers and 40 mothers) and 80 parents at low risk (40 fathers and 40 mothers) for physical child abuse were selected. The Subtle Expression Training Tool/Micro Expression Training Tool ( [Ekman, 2004a] and [Ekman, 2004b]) and the Diagnostic Analysis of Nonverbal Accuracy II (Nowicki & Carton, 1993) were used to assess emotion recognition.

Results

As expected, parents at high risk, in contrast to parents at low risk, showed deficits in emotion recognition. However, differences between high- and low-risk participants were observed only for fathers, but not for mothers. Whereas fathers at high risk for physical child abuse made more errors than mothers at high risk, no differences between mothers at low risk and fathers at low risk were found. No interaction between stress, gender, and risk status was observed for errors in emotion recognition.

Conclusions and practice implications

The present findings, if confirmed with physical abusers, could be helpful to further our understanding of deficits in processing information of physically abusive parents and to develop treatment strategies specifically focused on emotion recognition. Moreover, if gender differences can be confirmed, the findings could be helpful to develop specific treatment programs for abusive fathers.     

Adolescents’ future wishes and fears in their acculturation process

In this study we aim at learning about adolescents’ future fears and wishes from different cultural origins with a view to finding implications for intervention in the furthering of their satisfaction and social integration in their acculturation process. The study sample comprised 938 secondary school students—64.4% Spanish, 19.7% South American and 12.8% African. Wishes and fears were evaluated by means of two open questions and the answers were categorized following traditional content analysis methodology. Results show that the adolescents wish for a satisfactory job, family and economic situation, and that they are concerned about aspects such as their own health and that of their family, the possibility of having a precarious job, isolation from their family of origin, and not forming a family. The findings also allow us to give differential profiles according to the cultural origin of the adolescents.     

Separation and enrichment of sodium-motile bacteria using cost-effective microfluidics

Many motile bacteria are propelled by the rotation of flagellar filaments. This rotation is driven by a membrane protein known as the stator-complex, which drives the rotor of the bacterial flagellar motor. Torque generation is powered in most cases by proton transit through membrane protein complexes known as stators, with the next most common ionic power source being sodium. Sodium-powered stators can be studied through the use of synthetic chimeric stators that combine parts of sodium- and proton-powered stator proteins. The most well studied example is the use of the sodium-powered PomA-PotB chimeric stator unit in the naturally proton-powered Escherichia coli. Here we designed a fluidics system at low cost for rapid prototyping to separate motile and non-motile populations of bacteria while varying the ionic composition of the media and thus the sodium-motive force available to drive this chimeric flagellar motor. We measured separation efficiencies at varying ionic concentrations and confirmed using fluorescence that our device delivered eightfold enrichment of the motile proportion of a mixed population. Furthermore, our results showed that we could select bacteria from reservoirs where sodium was not initially present. Overall, this technique can be used to implement the selection of highly motile fractions from mixed liquid cultures, with applications in directed evolution to investigate the adaptation of motility in bacterial ecosystems.     

Gay–straight alliance (GSA) members’ engagement with sex education in Canadian high schools

This paper offers an examination of gay–straight alliance (GSA) members’ engagement with sex education, sexual health, and prejudice and discrimination in Canadian public high schools. It explores how five students’ (four straight and one gay-identifying) participation in GSAs served as a springboard for learning about and challenging stereotypes; prejudice; and discrimination directed at lesbian, gay, bisexual, trans, and queer/questioning (LGBTQ) people. Queer theory provided the theoretical underpinnings of the study, offering a lens through which to examine the heteronormative underpinnings of education, and a means to interpret how homophobic discourses circulate in school and society. Empirical data were obtained via observational notes from visits to nine GSAs and semi-structured interviews with the five GSA members. Findings suggest that straight allies can use their heterosexual privilege to address LGBTQ issues with their peers. Through GSA involvement, participants learned to interrogate and combat stereotypes about LGBTQ people and HIV-related myths, as well as to engage in queer discussion and political action.

“I am thinking that speech is asinine”: Narrating Complexities and Rethinking the Notion of “Independence” in Communication

This article presents a narrative accounting of a critical interpretivist research study that sought to document the emergence of useful speech in participants who had previously been described as largely nonverbal. The purpose of this piece is to narrate this inquiry process through examination not only of our participants' own accounts of their experiences but also through critical examination of the ways in which we as researchers solicit and respond to those accounts. Our analytic gaze, therefore, focuses on the dialectic process through which we interactively co-construct concepts related to disability in our participants' experiences, alternating between narrating our own experience of this process as researchers and narrating our participants' accounts of their own experiences with this interpretive process. Discussion focuses on critique of the cultural value accorded to the notions of “independence” and “normalcy,” and on the participants' demonstration of their own agency in the complex, fluid, and constant process of managing and constructing, in concert with those around them, and often in the face of significant resistance to the process, their own positive and valued identities as competent communicators.
