National and Regional Estimates of the Prevalence of Opiate and/or Crack Cocaine use 2008-09: A summary of key findings
<p>This report summarises the results of a follow-up study
to a three year project to estimate the prevalence of
‘problem drug use’ (defined as use of opiates and/or
crack cocaine) nationally (England only), regionally and
locally. The follow-up was carried out two years after the
final sweep of the original project, so could therefore
be considered as ‘sweep 5’. An overview of the national
and regional estimates are presented in this report, as are
comparisons with the estimates produced by the third
(2006-07) sweep of the study. Estimates for 2007-08 are
not available as a study was not commissioned for that
year.</p>
<p>Information about the number of people who use illicit
drugs such as heroin, other opiates or crack cocaine
is key to formulating effective policies for tackling
drug-related harm as these drugs are associated with
the highest levels of harm. It also helps inform service
provision at the local level and provides a context
in which to understand the population impact of
interventions to reduce drug-related harm.</p>
<p>Direct enumeration of those engaged in a largely covert
activity such as the use of class A drugs is difficult
and standard household survey techniques tend to
underestimate the extent of such activity. Indirect
techniques making use of various data sources offer a
more reliable way of calculating prevalence estimates for
the use of opiates and/or crack cocaine. The estimates
presented in this report are derived using two indirect
measurement techniques: the capture-recapture
method (CRC ); and the multiple indicator (MIM ) method.
These methods are described in detail in Hay et al., 2006
and Hay et al., 2007a. Methodological developments
throughout the course of the previous three sweeps are
discussed elsewhere (Hay et al., 2007b, Hay et al., 2008).
The individuals covered by this study were people aged
15 to 64 and resident in each DAT area, and known to
be using heroin, methadone, other opiate drugs or
crack cocaine.</p>

Anti-Trust and Economic Theory: Some Observations from the US Experience
Recent developments in US anti-trust can be characterised as reflecting the uneasy interaction of two quite separate phenomena: first, the increased emphasis on economic analysis as the overriding organising principle of anti-trust policy and on economic efficiency as the primary (perhaps only) relevant goal for anti-trust; second, the long-standing reluctance of the federal judiciary to involve itself in any substantive economic analysis, and the preference, instead, for simple rules of thumb or ‘pigeon holes’ to sort out lawful from unlawful conduct. The result has been that while economics has played a major role, it has not influenced American anti-trust as thoroughly or as uniformly as might have been imagined; rather the extent and the nature of its influence have depended on the degree to which the relevant economics could be reduced to the kind of simple rules or pigeon holes that the judiciary favours. The present paper will illustrate that theme, first by reporting on the two developments separately and then by illustrating their joint influence with reference to two important areas of American anti-trust: predatory conduct and so-called vertical restraints. Finally, a contrast will be made between judicial development in those two areas and recent American merger policy which, it is argued, is carried out largely independently of the judiciary, and hence the opportunities for economics to influence the process are less inhibited by the judicial reluctance to undertake extensive economic analysis
Interpersonal emotion regulation: a review of social and developmental components
A staple theme in clinical psychology, emotion regulation, or the ability to manage one's emotions, is directly linked with personal wellbeing and the ability to effectively navigate the social world. Until recently, this concept has been limited to a focus on intrapersonal processes, such as suppression. Less emphasis has been placed on developmental, social, and cultural aspects of emotion regulation. We argue here that as social beings, our engagement in emotion regulation may often occur interpersonally, with trusted others helping us to regulate our emotions. This review will highlight recent research on interpersonal emotion regulation processes.Dr Hofmann receives financial support from the Alexander von Humboldt Foundation (as part of the Humboldt Prize), NIH/NCCIH (R01AT007257), NIH/NIMH (R01MH099021, U01MH108168), and the James S.

Sexual Scripts and Sex Tips: Construction of the Spiciest Subject Through Sex Educational Content on TikTok
This thesis investigates the changing shape of sex education online, particularly sex education that is pointed toward young audiences in algorithmically-constrained communities on TikTok. Drawing from rhetorical theory, critical sexuality studies, and critical algorithm studies, I situate sex education on TikTok within a broader paradigm of sexual scripting and sexual subjectification processes that participate in the cultural neoliberal sphere. I explore how sex educational TikToks rhetorically construct technosexual agents through digital pedagogies while navigating complex algorithmic constraints—and to do so, I analyze two emergent sexual scripts in these videos: that of orgasm and aftercare. While orgasm discourses fold neatly into previous scholarship on neoliberal self-optimization and disciplinary devices, aftercare’s roots in BDSM communities construct sexual subjects along a different vector, where rhetorical agency and power-conscious dialectics resist traditional sex education’s re/productive goals. Ultimately, I introduce a framework to begin conceptualizing the rhetorical construction of sexual subjects under a neoliberal cultural paradigm complicated by TikTok’s algorithmic constraints, without losing sight of the restorative potential that emerges from the collision of disperse sexual epistemes

Uncertainties in land use data
This paper deals with the description and assessment of uncertainties in land use data derived from Remote Sensing observations, in the context of hydrological studies. Land use is a categorical regionalised variable reporting the main socio-economic role each location has, where the role is inferred from the pattern of occupation of land. The properties of this pattern that are relevant to hydrological processes have to be known with some accuracy in order to obtain reliable results; hence, uncertainty in land use data may lead to uncertainty in model predictions. There are two main uncertainties surrounding land use data, positional and categorical. The first one is briefly addressed and the second one is explored in more depth, including the factors that influence it. We (1) argue that the conventional method used to assess categorical uncertainty, the confusion matrix, is insufficient to propagate uncertainty through distributed hydrologic models; (2) report some alternative methods to tackle this and other insufficiencies; (3) stress the role of metadata as a more reliable means to assess the degree of distrust with which these data should be used; and (4) suggest some practical recommendations
