Constructing citizenship at the margins: the case of young graffiti writers in Melbourne

Young people engaging in graffiti are often portrayed as the anti-thesis of the ‘good citizen’. As politicians and the media fight the ‘war on graffiti’, these young people are tagged as criminals and misfits, overlooking the ways this arts practice reclaims their ability to tell stories and unhinge traditional ways of practicing citizenship. Using ideas from Michelle Fine et al.’s social psychology of spatiality as a conceptual lens, this paper explores the tensions, contradictions and binaries these young people find themselves caught between, particularly; art or vandalism, professional or amateur, artist or criminal, and legitimate or illegitimate citizens as young people and transgressors of ‘normal behaviour’ in public spaces. Using multiple methods, including ‘hanging out’ and participatory visual methods, this study explores how young graffiti artists’ experiences in and out of a legal ‘street art’ programme, speak back to ‘normative’ conceptualisations of citizenship. Their experiences of differential belonging and contested citizenship, which are played out in public spaces (and beyond), highlight the importance of alterative arts programmes and the creation of sanctioned spaces in negotiating young people’s ‘right to the city’.     

Combining Experts: Decomposition and Aggregation Order

In this article we ask, if quantities in an elicitation have been decomposed, is it better to combine experts before or after recomposing the quantities? We find that combining experts earlier, before recomposition of the quantities, leads to smaller errors with less variance. A simulation shows that these differences may be quite small on average; while an application to actual data shows that the differences can be significant in individual decision problems.     

Eliciting and Combining Decision Criteria Using a Limited Palette of Utility Functions and Uncertainty Distributions: Illustrated by Application to Pest Risk Analysis

Utility functions in the form of tables or matrices have often been used to combine discretely rated decision‐making criteria. Matrix elements are usually specified individually, so no one rule or principle can be easily stated for the utility function as a whole. A series of five matrices are presented that aggregate criteria two at a time using simple rules that express a varying degree of constraint of the lower rating over the higher. A further nine possible matrices were obtained by using a different rule either side of the main axis of the matrix to describe situations where the criteria have a differential influence on the outcome. Uncertainties in the criteria are represented by three alternative frequency distributions from which the assessors select the most appropriate. The output of the utility function is a distribution of rating frequencies that is dependent on the distributions of the input criteria. In pest risk analysis (PRA), seven of these utility functions were required to mimic the logic by which assessors for the European and Mediterranean Plant Protection Organization arrive at an overall rating of pest risk. The framework enables the development of PRAs that are consistent and easy to understand, criticize, compare, and change. When tested in workshops, PRA practitioners thought that the approach accorded with both the logic and the level of resolution that they used in the risk assessments.     

Employee feedback technologies in the human performance system

Many authors have noted that organizations are realizing that employees can be a major source of competitive advantage. A hidden source of advantage can be the improved utilization of existing human capital. A method common to most organizations for improving existing human capital is using employee feedback technologies. During a review of the literature it was found that employee feedback is an expanding and poignant subject. This paper describes some of the current leading technologies in employee feedback, including coaching, 360 degree feedback, as well as other techniques found in the literature. Methodologies of employee feedback including approaches and timeframes will be investigated at the system and process level. Finally, the opportunities for dealing with a problem employee using feedback are discussed.     

'Unnatural Acts': Discourses of homosexuality within the House of Lords debates on gay male law reform

Between 1998 and 2000, the House of Lords in the United Kingdom debated and rejected a Bill to equalise the age of sexual consent for gay men with the age of consent for heterosexual sex at sixteen years. A corpus‐based keywords analysis of these debates uncovered the main lexical differences between oppositional stances, and helped to shed light on the ways that discourses of homosexuality were constructed by the Lords. In the debates the word homosexual was associated with acts, whereas gay was linked to identities. Those who argued in favour of law reform focused on a discourse of equality and tolerance, while those who were against law reform constructed homosexuality by accessing discourses linking it to danger, ill health, crime and unnatural behaviour. The discussion focuses on the ways that discourses can be constructed via chains of argumentation.     

Reducing Adolescent Career Indecision: The ASVAB Career Exploration Program

An independent evaluation of the Armed Services Vocational Aptitude Battery (ASVAB) Career Exploration Program was conducted using nationally representative samples of high school students. The sample consisted of current ASVAB Program participants (n = 255) and two control groups of nonparticipants (n = 233, n = 189). A pretest‐posttest design showed that participation in the ASVAB Program increased career exploration knowledge and reduced diffusion and approach‐approach forms of career indecision, as assessed by the Career Decision Scale (S. Osipow, 1986).     

Mental health and behavioral problems of youth in the child welfare system: residential treatment centers compared to therapeutic foster care in the Odyssey Project population

This is the first multisite, prospective study of behavioral and mental health disorders of youth in residential treatment centers (RTC) and therapeutic foster care (TFC), and the first study to compare the two. This study addressed two questions in a sample of 22 agencies in 13 states: (1) how prevalent were emotional and behavioral disorders in the youth admitted to RTCs and TFC?, and (2) were the youth in RTCs significantly more likely to be disturbed than youth served in TFCs? Data were drawn from the Time 1 phase of the longitudinal national "Odyssey Project" developed by the Child Welfare League of America (1995). Measures included an extensive child and family characteristics form (CFC) and the Child Behavior Checklist (CBCL). The results revealed extremely high levels of behavioral and mental health disorders in the sample as a whole, well above the norms for a non-child welfare population. The prevalence of disorder in the RTC population was substantially greater than in the TFC population.     

Effect of consumption choices on fluxes of carbon,nitrogen and phosphorus through households

Households are an important scale of analysis for human ecosystems because they are a major source of pollutants and could thus be a new focus for pollution management, particularly for education-based source reduction strategies. The household is also a meaningful unit for analysis of human ecosystems, being common to all human cultures. This study develops a Household Flux Calculator (HFC) to compute C, N, and P fluxes for scenarios intended to represent three levels of household consumption: low, typical, and high. All three scenarios were developed for suburban households with two adults and two children in the Minneapolis-St. Paul (Twin Cities) metropolitan area, Minnesota. Calculated ratios of fluxes between high and low consumption households were 3.5:1 for C, 2.7:1 for N and 1.4:1 for P. Results suggest a high level of discretionary consumption that could be reduced without a substantial reduction in standard of living. Thus, modest changes in behavior in high consumption households would greatly reduce fluxes of C, N, and P without major changes in lifestyle.

Deterministic Evolution of Strength in Multiple Comparisons Models: Who is the Greatest Golfer?

We present a statistical methodology for fitting time‐varying rankings, by estimating the strength parameters of the Plackett–Luce multiple comparisons model at regularly spaced times for each ranked item. We use the little‐known method of barycentric rational interpolation to interpolate between the strength parameters so that a competitor's strength can be evaluated at any time. We chose the time‐varying strengths to evolve deterministically rather than stochastically, a preference that we reason often has merit. There are many statistical and computational problems to overcome on fitting anything beyond ‘toy’ data sets. The methodological innovations here include a method for maximizing a likelihood function for many parameters, approximations for modelling tied data and an approach to the elimination of secular drift of the estimated ‘strengths’. The methodology has obvious applications to fields such as marketing, although we demonstrate our approach by analysing a large data set of golf tournament results, in search of an answer to the question ‘who is the greatest golfer of all time?’
