Re-Orientating Vertical Geopolitics

Geopolitics has a tradition of adopting a downward looking view-from-above, which is imbued with an imperialistic ‘god's eye’ perspective. Although acknowledged and critiqued, this paper argues that it needs to be actively re-orientated to encompass the discourses and practices of looking up. The paper analyses the practices of looking up and surveilling the sky through which air defence is achieved. It interrogates the ways in which UK air defence is represented in official documents and analyses the activities of the Royal Air Force's Air Surveillance and Control System. The paper argues that this system enacts a vertical geopolitics that goes beyond those understood in other geopolitical literatures and offers suggestions for developing our understandings of a volumetric vertical geopolitics that recognises the aerial view as generated from below as well as from above.     

Exploring the effectiveness of peer mentoring of accounting and finance students in higher education

This article explores the effectiveness of peer mentoring with accounting and finance students at the University of Dundee. The motives of such a mentoring scheme are to improve the participants' academic performance and to develop their transferable skills. In the context of this study, peer mentoring comprises third year students (mentors) mentoring first year students (mentees). Using a semi-formal tutorial setting and meetings during the latter part of the academic year, mentoring groups address issues such as academic writing skills, study techniques and examination preparation. The effects of mentoring are measured by a comparison of the pre- and post-mentoring examination performance of the mentees. In addition, focus group interviews are used to gather the opinions of the mentees and the mentors as to their impressions about the success of the project. The empirical results suggest that mentoring has had a positive effect on the academic performance of the mentees. The focus group interviews found that both the mentors and the mentees claimed to benefit significantly from their involvement in the project.     

The presence of an error term does not preclude causal inference in regression: a comment on Krause (2012)

A recent article by Krause (Qual Quant, doi:10.1007/s11135-012-9712-5, Krause (2012)) maintains that: (1) it is untenable to characterize the error term in multiple regression as simply an extraneous random influence on the outcome variable, because any amount of error implies the possibility of one or more omitted, relevant explanatory variables; and (2) the only way to guarantee the prevention of omitted variable bias and thereby justify causal interpretations of estimated coefficients is to construct fully specified models that completely eliminate the error term. The present commentary argues that such an extreme position is impractical and unnecessary, given the availability of specialized techniques for dealing with the primary statistical consequence of omitted variables, namely endogeneity, or the existence of correlations between included explanatory variables and the error term. In particular, the current article discusses the method of instrumental variable estimation, which can resolve the endogeneity problem in causal models where one or more relevant explanatory variables are excluded, thus allowing for accurate estimation of effects. An overview of recent methodological resources and software for conducting instrumental variables estimation is provided, with the aim of helping to place this crucial technique squarely in the statistical toolkit of applied researchers.     

The return from travel: a new beginning?

Within the context of the return from long-term travel, this paper uncovers the transitional and at times traumatic nature of return for 24 OE (overseas experience) travellers. Important considerations are raised in respect of easing repatriation distress among those returning from long-term travel. Contributing an understanding of the experience of return from travel, this paper proffers that return to the place one left to travel from does not necessarily mark the end of the journey. Conversely, it can mark a new beginning. As such, we argue that a broader framework for examining the travel experience is called for; notably, one that extends the examination of the travel experience to the return phase and beyond.     

Social class, family background, and intergenerational mobility

This research examines the various approaches taken by economists and sociologists for analyzing intergenerational mobility. Social mobility models based on social classes arising from an occupational classification scheme are analysed. A test for the statistical validity of classification schemes is proposed and tested using Danish sample survey data that was first collected in 1976 and augmented in 2000. This is referred to as a homogeneity test and is a likelihood ratio test of a set of linear restrictions which define social classes. For Denmark it is shown that this test fails for an Erikson-Goldthorpe classification system, raising doubts about the statistical validity of occupational classification systems in general. We also estimate regression models of occupational earnings, household earnings, and educational attainment using family background variables as covariates controlling for unobservables, measurement error, and simultaneous equation bias. In these models homogeneity tests are also rejected. We conclude from these results that the individual's family background has a small but significant impact on lifetime chances which is not captured by the Erikson-Goldthorpe classification scheme.     

Has Devolution Injured American Workers? State and Federal Enforcement of Construction Safety

Although the issue of regulatory devolution has received muchscholarly scrutiny, rigorous empirical studies of its effectson important policy outcomes are scarce. This article exploresthe effects of partial regulatory devolution in the occupationalsafety arena by exploiting a unique historical anomaly wherebysome US states enforce protective labor regulations that areenforced elsewhere by the federal Occupational Safety and HealthAdministration. Analyzing data from the construction industry,this article contains several important findings. First, stateinspectors use traditional enforcement tools more sparinglythan their federal counterparts, typically citing fewer violationsand collecting lower fines per violation. Second, although federalenforcement significantly lowers the estimated frequency ofnonfatal construction injuries, it also predicts a significantincrease in occupational fatalities. I suggest that althoughhigher underreporting of nonfatal injuries in federally regulatedstates could explain this puzzling finding, it is equally possiblethat different regulatory styles have different "comparativeadvantages" in deterring nonfatal injuries on one hand and occupationalfatalities on the other.

Enabling the language of accessible tourism

The growing body of literature on “accessible tourism” lacks a critical scholarly debate around its specific language use and nomenclatures. To fill this gap, this paper provides a first examination of language. Language provides a unique capability to resist, strengthen and reframe identities of individuals and groups, yet can also reinforce, weaken and perpetuate dominant worldviews of disability. A content analysis examined previous accessible tourism literature with results illustrating that diversity exists amongst the varying terminologies adopted by scholars. Terms were employed loosely, inconsistently and interchangeably, euphemistically with erroneous understandings and nuances. The paper concludes with critical discussion about the power of researchers to (re) produce oppression through language that maligns and misrepresents, or to (re) conceptualise and (re) construct the world we live in with liberating language that facilitates positive social change.     

Do Community Supported Agriculture programmes encourage change to food lifestyle behaviours and health outcomes? New evidence from shareholders

Community Supported Agriculture (CSA) programmes have recently received attention for their potential to influence food lifestyle behaviours and health outcomes, though studies have mostly drawn from small samples (n?t-tests assess if paired means are statistically different, and multiple regressions of paired differences on socioeconomic factors, self-reported health, and years of CSA enrolment estimate the effect of respondent characteristics on behaviour change. The results strongly suggest that CSAs have the potential to positively impact shareholders’ food lifestyle behaviours and health outcomes, and that those reporting ‘poor health’ prior to CSA enrolment exhibited the most change overall. These results should be taken as an initial, yet promising, analysis of the impact of CSA participation on shareholder food lifestyle behaviours and health outcomes.
