Risk and protective factors for recent alcohol use among African-American youth

A total of 7488 7th-12th grade African-American students completed a survey assessing factors associated with recent alcohol use. Results indicated that 13.6% used alcohol in the past month. A series of odds ratios revealed that making good grades, participating in school activities, attending church, and having parents/teachers talk about the dangers of alcohol and set/enforce rules regarding alcohol were associated with decreased recent use. Participating in risky behaviors such as getting into trouble, skipping school, and having friends who use alcohol and other drugs was directly related to recent use. Prevention specialists should encourage parents/teachers to engage youth in family, school, and community activities to deter alcohol use. Results may assist youth health professionals in developing prevention programs aimed at African-American youth.     

Discriminant Analysis Using Least Absolute Deviations

Several linear programming methods have been suggested as discrimination procedures. A least absolute deviations regression procedure is developed here which is simpler to use and does not suffer from any lack of invariance. A simulation study shows it to be at least as effective as any of the methods previously discussed for normal and heavy-tailed distributions.     

THE HERMITE DISTRIBUTION AS A MODEL OF DEMAND DURING LEAD TIME FOR SLOW-MOVING ITEMS

Heretofore, the Poisson and the Laplace distributions have been used to model demand during lead time for slow-moving items. In this paper, we present a Poisson-like distribution called the Hermite. The advantage of the Hermite is that it is as simple to use as the Poisson and the Laplace are. Moreover, the Hermite is the exact distribution of demand during lead time when unit demand is Poisson, P(Λ), and lead time is normally distributed, N(μ, σ²), so long as (μ/σ²)≥Λ. Thus, the Hermite can enhance the accuracy of analysis as well as add to the tools available to the analyst.     

Implementation of a Bayesian adaptive design in a proof of concept study

With increased costs of drug development the need for efficient studies has become critical. A key decision point on the development pathway has become the proof of concept study. These studies must provide clear information to the project teams to enable decision making about further developing a drug candidate but also to gain evidence that any effect size is sufficient to warrant this development given the current market environment. Our case study outlines one such proof of concept trial where a new candidate therapy for neuropathic pain was investigated to assess dose-response and to evaluate the magnitude of its effect compared to placebo. A Normal Dynamic Linear Model was used to estimate the dose-response--enforcing some smoothness in the dose-response, but allowing for the fact that the dose-response may be non-monotonic. A pragmatic, parallel group study design was used with interim analyses scheduled to allow the sponsor to drop ineffective doses or to stop the study. Simulations were performed to assess the operating characteristics of the study design. The study results are presented. Significant cost savings were made when it transpired that the new candidate drug did not show superior efficacy when compared placebo and the study was stopped.     

Shaped by place? Young people's aspirations in disadvantaged neighbourhoods

This paper aims to better understand the relationship between young people's aspirations towards education and jobs, and the context in which they are formed, especially to understand better the role of disadvantaged places in shaping young people's aspirations. Policy makers maintain that disadvantaged areas are associated with low aspirations and there is support for this position from academic work on neighbourhood effects and local labour markets, but evidence is slim. Using a two-stage survey of young people in disadvantaged settings in three British cities, the paper provides new data on the nature of young peoples’ aspirations, how they change during the teenage years, and how they relate to the places where they are growing up. The findings are that aspirations are very high and, overall, they do not appear to be depressed in relation to the jobs available in the labour market either by the neighbourhood context or by young people's perceptions of local labour markets. However, there are significant differences between the pattern of aspirations and how they change over time in the three locations. The paper then challenges assumptions in policy and in the literature that disadvantaged places equal low aspirations and suggests that understanding how aspirations are formed requires needs a nuanced approach to the nexus of class, ethnicity and institutional influences within local areas.     

Reporting and Justifying the Number of Interview Participants in Organization and Workplace Research

In this paper we examine established practice regarding the reporting, justification and number of interview participants chosen within organization and workplace studies. For such qualitative research there is a paucity of discussion across the social sciences, the topic receiving far less attention than its centrality warrants. We analysed 798 articles published in 2003 and 2013 in ten top and second tier academic journals, identifying 248 studies using at least one type of qualitative interview. Participant numbers were contingent on characteristics of the population from which they were chosen and approach to analysis, but not the journal, its tier, editorial base or publication year, the interview type or its duration. Despite lack of transparency in reporting (23.4% of studies did not state participant numbers) we reveal a median of 32.5 participants, numbers ranging from one to 330, and no justification for participant numbers in over half of studies. We discuss implications and, recognizing that different philosophical commitments are likely to imply differing norms, offer recommendations regarding reporting, justification and number of participants. Acknowledging exceptions, dependent upon study purpose and data saliency, these include an organization and workplace research norm of 15?60 participants, alongside credible numbers for planning interview research.     

Aliens and others: Between Girard and Derrida

Abstract

In the work of Levinas, thought of the Other establishes an infinite responsibility and in that of Derrida's latest work an infinite duty of hospitality. Such thought nonetheless leaves a problem of judgement and decision. This paper uses the work of the French philosopher René Girard, and in particular his account of scapegoating, to critically discern between malign and benign otherness. It argues that a logic of undecidability needs an ethical hermeneutics capable of discerning between good and evil.     

Shouts of the street: Identity and the spaces of authenticity

Abstract

For a long time the street has occupied a cherished place in the lexicon of urbanism. Romanticised as the site of authentic political action, celebrated and reviled as the font of ‘low’ culture or feared as a signifier of dangerous territorialisation, the street can be gazed at, walked through and appropriated time and again in representations of the city. This paper looks at some of the tensions in the notions of spatiality that are both masked and naturalised in our common use of the term.

The paper takes as its empirical focus the racialised and racist mobilisations that occurred in the East End of London in the late summer of 1993. A local by‐election with a very high profile BNP (fascist) presence, the racist assault on seventeen year old Qudddus Ali, which left him for several days near death in intensive care, and the subsequent clashes in Whitechapel and Spitalfields which sprang from attacks on the shops and restaurants of Brick Lane by far right activists culminated in serious clashes between police and local Bengalis and a petrol bomb attack on the local police station.

The paper shows that ‘the street’ invokes a range of spatialities that are a constitutive feature in understanding not only the parochial specificities of Spitalfields and Stepney, Wapping and Whitechapel, but also the very nature of racist and anti‐racist mobilisation. At times the vocabulary of resistance may appear similar or even identical to the language of the carceral and territorial imperatives that codify and institutionalise racist practices. On closer inspection subtle distinctions arise from particular articulations of street sensibilities, raising questions that are essential for a plausible and politically progressive reading of recent violent disorder and indispensable to an understanding of the constellation of contemporary debates around public space and the perennial discussion about ‘insiders’ and ‘outsiders’ in anti‐racist mobilisations.
