BOOK REVIEWS

Every so often, it is important to stand back and look at the whole context of our field of research and practice. In this article, I do this by shedding light on the ways we view the term vocations and the consequences of those views for education and training in community colleges and adult and community education providers of all kinds. I ask the question: What is Vocational Education and Training (VET) for? I ask this particular question because I know the answers are contested, staking out claims for territory in research and practice. The answer to the question that this article explores is that vocational education and training ''serve industry.'' Using Australia as a specific example of such a Western country, the article argues that the entrenched meanings for VET as serving industry have disenfranchised a large proportion of the population - especially small business and the rural sector. The article is pointing out that the resulting version of VET is gendered, classed, and urban-specific. This structurally entrenched position is then contrasted with data reported from empirical studies currently examining (among other things) the nature of vocations and work at a community level and the manner in which they are created there. The article raises three important implications: the convergence of Adult and Community Education with VET, learning pathways, and the effects on small business.     

Community‐based early intervention for children with behavioural,emotional and social problems: evaluation of the Scallywags Scheme

Scallywags is a community‐based, early intervention programme for young children (aged 3–7) with behavioural, emotional and social problems, which integrates work in the home and school with a parenting curriculum and direct work with children. A pre‐post intervention study across multi‐sites of 340 participants is reported. Using standardised measures, the study found statistically significant reductions in problems at home and school experienced by children who completed the programme, and in parental stress levels. Participation was found to be high and the project acceptable to parents, many of whom would be described as hard to reach. The rigorous evaluation of this real‐life service and its positive outcomes highlight the potential of such programmes to tackle the needs of these children and families, and help prevent longer‐term problems associated with early onset behavioural problems, including social exclusion, antisocial behaviour and educational failure.     

Bullying, ‘cussing’ and ‘mucking about’: complexities in tackling homophobia in three secondary schools in south London,UK

In countries such as the UK, schools have a responsibility to prevent all forms of bullying, including those related to sexual orientation. However, relatively little is known about how schools go about this work successfully. This study aimed to identify how three secondary schools in south London, England, were addressing homophobia. Three different kinds of schools – a co-educational, boys' and girls' school – were selected, each known to have conducted work to counter homophobic bullying. In each school, interviews were conducted with staff and pupils. Work on homophobia and homophobic bullying was said by most staff respondents to be part of a general commitment to countering bullying. Pupils stated that they were keen that homophobic bullying should be tackled – and distinguished bullying from ‘cussing’, ‘taking the mick’ and ‘mucking about’. Work carried out in schools had influenced pupils to consider homophobia and its effects – although the media as well as personal and family relationships were also important in this respect. Findings are discussed with regard to ways in which schools might better align what they do with regard to pupils' own values and understandings about how best to address homophobia and bullying.     

Assessing intellectual potential in Tanzanian children in poor areas of Dar es Salaam

The research set out in this paper attempts to identify whether one of three conventional IQ tests is more capable of identifying intellectual potential amongst poor children in Dar es Salaam. To this end 1857 children from 17 government schools in poor districts of Dar es Salaam were asked to complete a questionnaire and undertake a range of tests. The study included teacher, peer and self-nomination. It has been noted that static testing may not fully elicit the abilities of African children. It has been suggested that dynamic testing might provide a more fair and equitable means of assessment. Therefore 101 students took part in a control and intervention group in order to investigate. The findings show a significant correlation between IQ test scores and other test outcomes. Those with larger families and older children perform less well on IQ tests. Peer ability and self-confidence positively influence test scores.     

Size-dependent trajectories of DNA macromolecules due to insulative dielectrophoresis in submicrometer-deep fluidic channels

In this paper, we demonstrate for the first time that insulative dielectrophoresis can induce size-dependent trajectories of DNA macromolecules. We experimentally use λ (48.5 kbp) and T4GT7 (165.6 kbp) DNA molecules flowing continuously around a sharp corner inside fluidic channels with a depth of 0.4 μm. Numerical simulation of the electrokinetic force distribution inside the channels is in qualitative agreement with our experimentally observed trajectories. We discuss a possible physical mechanism for the DNA polarization and dielectrophoresis inside confining channels, based on the observed dielectrophoresis responses due to different DNA sizes and various electric fields applied between the inlet and the outlet. The proposed physical mechanism indicates that further extensive investigations, both theoretically and experimentally, would be very useful to better elucidate the forces involved at DNA dielectrophoresis. When applied for size-based sorting of DNA molecules, our sorting method offers two major advantages compared to earlier attempts with insulative dielectrophoresis: Its continuous operation allows for high-throughput analysis, and it only requires electric field strengths as low as ∼10 V∕cm.     

Evaluating epistemic uncertainty under incomplete assessments

The thesis of this study is to propose an extended methodology for laboratory based Information Retrieval evaluation under incomplete relevance assessments. This new methodology aims to identify potential uncertainty during system comparison that may result from incompleteness. The adoption of this methodology is advantageous, because the detection of epistemic uncertainty – the amount of knowledge (or ignorance) we have about the estimate of a system’s performance – during the evaluation process can guide and direct researchers when evaluating new systems over existing and future test collections. Across a series of experiments we demonstrate how this methodology can lead towards a finer grained analysis of systems. In particular, we show through experimentation how the current practice in Information Retrieval evaluation of using a measurement depth larger than the pooling depth increases uncertainty during system comparison.     

Breaking up is hard to do: the resilience of the rock group as an organizational form for creating music

Though there is a long tradition of band members quitting the group or taking a hiatus, the rock group as an organization to produce music continues to be both popular and economically viable. The research question addressed in this paper is whether or not it is a good idea to quit or take a hiatus from the group. We begin with a discussion of the framework for understanding why groups are formed and why they may be difficult to keep together. We then discuss differences between groups in the decade of the 1960s versus today. We argue that there is something unique about the output of the group even with the changes in the structure of contracts, compensation, and consumer focus on the artist that explain the resilience of the rock band as an organizational form within which to create music. We compare the charting success of bands that have members leave the group with the charting success of the members who left the group. We identified the groups in five representative years: 1965, 1975, 1985, 1995, and 2005. We then analyzed the entire Billboard Hot 100 charting careers of those groups and the artists who quit those groups. Our main finding is that when charting success is divided equally among members, going solo pays off—there is a clear economic rationale because solo acts have greater average charting success than the original bands they started in. The other ensuing side projects: duos, collaborations, and other groups are not as lucrative as the original bands. These findings are valid for members of charting groups from each of the 5 years examined. Despite the difficulties in keeping a rock band together, there are fewer band breakups today and remaining with the group generally results in a longer and more productive charting career. Thus, the rock group remains an important organization for producing contemporary music. However, there remains a compelling incentive to go solo. Superstars may benefit from solo projects, but for the average, non-superstar group member, in many circumstances it is better for the band to stay together if the income is divided equally.
