A Comparison of Spinal Manipulation by Medical Practitioners and Chiropractors

Recent studies have shown that a significant proportion of the Australian population attend chiropractors. In so far as some patients believe that chiropractic manipulation is effective, it is important to determine whether this belief is a consequence of a psychosomatic remission in symptoms or whether manipulative therapy, per se, is actually effective. A comparison of two groups of 50 patients, matched for condition and some demographic characteristics, treated (with manipulation) by doctors or chiropractors, indicates equivalent and widespread improvement in the presenting symptoms. The psychosomatic explanation is unlikely to be adequate and it may be that manipulation of the spine is effective therapy for some conditions.     

VIRALITY 2.0

Media virality is a current fetish object in a number of overlapping contexts including marketing, IT design and academia. The desirability of media ‘going viral’ is confirmed by efforts now undertaken to categorize viral success through a range of typologies and metrics, conceived in order to predict and achieve virality. A recent online ad campaign, staged as a ‘how to make a viral video’, signals the complexity of the concept of manufactured virality. This article takes as a point of departure a moment of conceptual slippage in the commercial to argue that the current discourse of media virality has paradoxically expelled its own progenitor, the virus. Contrary to Henry Jenkins's claim that the discourse of virality is ‘a kind of smallpox-soaked blanket theory of media circulation’, I argue that as transmission has been rebranded as ‘sharing’, questions of personal and moral responsibility attendant to transmission and infection have been erased in favour of a bland ideology of interactivity. The concept of ‘virality 2.0’ is proposed to account for this double movement: that the discourse of digital virality has relegated viruses to the past, while structurally exploiting their dynamic of circulation. Moreover, virality 2.0 reinscribes viral subject positions with normative values drawn from this same cultural past. The argument is supported by three main claims. First, behaviour deemed risky and marginal within a heteronormative discourse of promiscuity has been reappropriated as ‘sharing’ and ‘leadership’. Second, practices of digital media transmission may be as much about systemic functionality as active and engaged participation. And third, post-viral media virality works to stabilise and fetishise the active ‘sharing subject’ in neoliberal and heteronormative terms, at the expense of other practices and pleasures.     

An empirical approach to determine a threshold for assessing overdispersion in Poisson and negative binomial models for count data

Overdispersion is a problem encountered in the analysis of count data that can lead to invalid inference if unaddressed. Decision about whether data are overdispersed is often reached by checking whether the ratio of the Pearson chi-square statistic to its degrees of freedom is greater than one; however, there is currently no fixed threshold for declaring the need for statistical intervention. We consider simulated cross-sectional and longitudinal datasets containing varying magnitudes of overdispersion caused by outliers or zero inflation, as well as real datasets, to determine an appropriate threshold value of this statistic which indicates when overdispersion should be addressed.     

Two Decades of Stability and Change in Age at First Union Formation

The landscape of union formation has been shifting; Americans are now marrying at the highest ages on record and the majority of young adults have cohabited. Yet little attention has been paid to the timing of cohabitation relative to marriage. Using the National Survey of Families and Households and 4 cycles of the National Survey of Family Growth, the authors examined the timing of marriage, cohabitation, and unions over 20 years. As the median age at first marriage has climbed, the age at cohabitation has remained stable for men and women. The changes in the timing of union formation have been similar according to race/ethnicity. The marked delay in marriage among women and men with low educational attainment has resulted in a near‐convergence in the age at first marriage according to education. The authors conclude that the rise in cohabitation has offset changes in the levels and timing of marriage     

Juvenile Reoffending: a ten‐year retrospective cohort analysis

Criminologists and other developmental researchers have long acknowledged the importance of both continuity and change in antisocial and criminal behaviour over the life‐course. To the extent that young offenders having contact with the police will persist with offending into adulthood is an important social issue with significant implications for the ongoing development and implementation of early intervention and prevention programs. Using data from New South Wales, this paper tracks a cohort of 8,797 juvenile offenders over ten years and is among the first of its kind to use multivariate techniques to examine the long‐term outcomes of those who were cautioned, conferenced or convicted in that state. The study finds that just over half of all juvenile offenders were reconvicted in court of a further offence and that reconviction rates were higher for young males and Indigenous offenders than for females or non‐Indigneous offenders. In concluding, this paper draws attention to the need for improved assessment and early intervention efforts that more accurately target those young people most at risk of persisting with offending into adulthood.     

Emotional Labour and Skill: A Reappraisal

The article seeks to open up a critical discussion around the idea of emotional labour as skilled work. It has been suggested by some commentators that many front‐line service jobs, traditionally thought of as low skilled in terms of their technical aspects, may actually constitute a form of skilled work, since they require their holders to perform skilled emotional labour in their dealings with customers. Such discourses hold out the possibility of progress not only in intellectual terms but also with regard to improving the status and pay of many low‐waged service workers. The article subjects these claims to critical scrutiny and argues that applying the label ‘skill’ to all forms of emotion work is extremely problematic.
