An Australian study of possible selves perceived by undergraduate engineering students

In this study, we worked with second-year engineering students at an Australian university to examine previously identified threshold concepts within the theoretical framework of Possible Selves. Using workshops as the context for intensive work with students, students were encouraged to consider their future lives and work, including their engineering fears, expectations, and aspirations. The findings revealed many students to have a poor understanding of the realities of engineering work. Moreover, perceived gaps between self-efficacy and the requirements of engineering work appeared to be motivating if students deemed it possible to reduce the gap, but demotivating if they identified a characteristic over which there was perceived to be no control. The study suggests that these engineering students needed more opportunities to explore both the roles of engineers and their own possible selves. Overall, the findings indicate that higher education students may need encouragement and support to explore potential future roles, and they strengthen calls for further research in this area.     

The role of inhibitory associations in perceptual learning

Preexposure to two compound flavors (AX and BX) typically enhances their discriminability: An aversion conditioned to AX will generalize less to BX, especially if the preexposure regime has involved alternated presentations of AX and BX rather than presenting all AX trials before BX trials (or vice versa). One possible explanation of this finding is that alternating preexposure establishes inhibitory associations between the two unique features A and B, thus counteracting the generalization produced by excitatory associations between X and A and between X and B, which might result in either the retrieval of B on a conditioning trial to AX, or the retrieval of A on a test trial to BX. Three experiments on flavor aversion conditioning in rats tested these predictions. Experiment 1 suggested that the more important of these excitatory associations was that which allowed X to retrieve A on the test trial to BX. Experiment 2 suggested that the more important inhibitory association was that which allowed B to inhibit the representation of A on this test trial. Experiment 3 provided direct evidence of the role of this inhibitory B⊣A association.     

The need for a General Comment for Article 19 of the UN Convention on the Rights of the Child: Toward enlightenment and progress for child protection

ObjectiveTo present the need and plan for development of a General Comment for the UN Convention on the Rights of the Child Article 19 which has the potential to transform and advance child protection through the infusion of a child rights approach.MethodsThe Committee on the Rights of the Child (Committee) authorized ISPCAN and IICRD to draft a General Comment for CRC Article 19 (GC19) and to introduce implementation supports. An international working group (GC19WG), Expert Advisory Panel (EAP), and GC19 Focal Group of Committee members (GC19 CRC FG) have been organized to help guide and carry out the program of development. Analyses of relevant histories and knowledge, including effective and promising child protection strategies, are being applied to guide formulation of the GC and high priority implementation components. Consultations on the draft and supportive products will be conducted in cooperation with UNICEF, WHO, the NGO Group for the CRC, and other NGOs.Advice is to be solicited from interested parties and organizations in person and through distance communication throughout the world.ResultsIn addition to the GC19, numerous implementation supports will be planned and some will be produced and piloted during the program of development. Under consideration are an implementation guide and resources; commentary; accountability models, indicators, measures and evaluation systems; a clearing house and resource website; a child-appropriate version of GC19; and education/training curricula and programs.Practice implicationsGC19 has the potential to transform child protection by fostering a paradigm shift in its conceptualization, theory, research, and practice. Article 19 encourages an interpretation and application beyond narrow child protection conceptualizations and practices which have been found seriously inadequate. The General Comment can advance effective prevention of maltreatment and protection of personal security by promoting the child's rights, well-being, health, and development in all aspects of child protection. GC19 will provide support to the Committee on the Rights of the Child in its monitoring and guiding functions, and to States Parties, professionals, and civil society agents concerned with the protection and well-being of children.     

Exploratory assessments of child abuse: Children's responses to interviewer's questions across multiple interview sessions

ObjectiveThe present study extends field research on interviews with young children suspected of having been abused by examining multiple assessment interviews designed to be inquisitory and exploratory, rather than formal evidential or forensic interviews.MethodsSixty-six interviews with 24 children between the ages of 3 and 6 years who were undergoing an assessment for suspected child abuse were examined. Each child was interviewed 2, 3, or 4 times. The interviewer's questions were categorized in terms of openness (open, closed or choice), in terms of the degree of interviewer input (free recall, direct, leading, suggestive), and for topic (whether the question was abuse-specific or nonabuse-related). Children's on-task responses were coded for amount of information (number of clauses) reported in relation to each question type and topic, and off-task responses were categorized as either ignoring the question or a diverted response.ResultsChildren provided a response to most questions, independent of question type or topic and typically responded with one or two simple clauses. Some children disclosed abuse in response to open-ended questions; generally, however, failure to respond to a question was more likely for abuse-specific than for nonabuse-related questions.ConclusionThe findings are discussed in terms of the growing literature on interviewing children about suspected abuse, particularly in interviews conducted over multiple sessions.Practice implicationsAssessment of suspected child abuse may involve more than a single investigative interview. Research examining children's responses to questioning over multiple interviews (or single interviews conducted over multiple sessions) is necessary for the development of best practise guidelines for the assessment of abuse.     

Formative computer‐based assessment in higher education: the effectiveness of feedback in supporting student learning

A formative computer‐based assessment (CBA) was one of three instruments used for assessment in a Bachelor of Education course at Queen’s University (Ontario, Canada) with an enrolment of approximately 700 students. The formative framework fostered a self‐regulated learning environment whereby feedback on the CBA was used to support rather than measure student learning. The four types of feedback embedded in the CBA included: (a) directing students to a resource, (b) rephrasing a question, (c) providing additional information and (d) providing the correct answer. Although students originally reported positive experiences with the formative CBA, two follow‐up surveys revealed that they found the four types of feedback to be moderately effective in supporting their learning.     

The interface between arts practice and research: attitudes and perceptions of Australian artist‐academics

Whilst an academic working in the arts may have been appointed as a consequence of artistic accomplishment and a capacity to teach, the research that underpins such work is an intrinsic part of its production and also needs to be recognised. In Australia, the ability of the artist‐academic to translate research into a form that is respected and rewarded is an issue of contention. This paper gathers responses to this issue. Perceptions of and attitudes to creative work as research are canvassed alongside life decisions arising from those perceptions and attitudes. This research occurs in the context of a new Australian framework for the evaluation of research. This framework offers some recognition of the research that supports creative practice. Thus, the long‐standing experience of compromise reported by the Australian artist‐academics interviewed for this study are discussed alongside new policies that seek to construct methodologies for its amelioration.     

Effect of verbal instructions and image size on visual search strategies in basketball free throw shooting

We assessed the effects on basketball free throw performance of two types of verbal directions with an external attentional focus. Novices ( n = 16) were pre-tested on free throw performance and assigned to two groups of similar ability ( n = 8 in each). Both groups received verbal instructions with an external focus on either movement dynamics (movement form) or movement effects (e.g. ball trajectory relative to basket). The participants also observed a skilled model performing the task on either a small or large screen monitor, to ascertain the effects of visual presentation mode on task performance. After observation of six videotaped trials, all participants were given a post-test. Visual search patterns were monitored during observation and cross-referenced with performance on the pre- and post-test. Group effects were noted for verbal instructions and image size on visual search strategies and free throw performance. The 'movement effects' group saw a significant improvement in outcome scores between the pre-test and post-test. These results supported evidence that this group spent more viewing time on information outside the body than the 'movement dynamics' group. Image size affected both groups equally with more fixations of shorter duration when viewing the small screen. The results support the benefits of instructions when observing a model with an external focus on movement effects, not dynamics.     

Digit ratio (2D:4D) and performance in elite rugby players

Abstract

The relative length of the second and fourth digits (2D:4D) is a putative marker for prenatal testosterone. Low 2D:4D has been reported to correlate with high performance in sport in general. Here, for the first time, we examine the relationship between 2D:4D and performance in elite rugby players. The 44 players (28 forwards, 16 backs) were drawn from the Ospreys Rugby Union Club and 44 age-matched controls. The measures of performance comprised age-adjusted number of international performances (caps) for Wales, a comparison of coaches' first-choice League team with others, and the number of tries scored by backs in club matches. Compared with controls, players were larger and had lower 2D:4D for the right and left hand. With regard to number of caps, players with low 2D:4D in their right hand and low right 2D:4D compared with their left (right ? left 2D:4D difference) had high numbers of caps. First-choice players did not differ significantly from second-choice players in their 2D:4D but they did have a lower right ? left 2D:4D difference than second-choice players. Low right 2D:4D and low right ? left 2D:4D difference were significantly linked with large numbers of tries. We conclude that low right 2D:4D and low right ? left 2D:4D difference are predictors of high rugby performance.
