How to humiliate and shame: A reporter's guide to the power of the mugshot

This is an Author's Accepted Manuscript of an article published in Social Semiotics, 24(1), 56-87, 2014, copyright Taylor & Francis, available online at: http://www.tandfonline.com/The judicial photograph – the “mugshot” – is a ubiquitous and instantly recognisable form, appearing in the news media, on the internet, on book covers, law enforcement noticeboards and in many other mediums. This essay attempts to situate the mugshot in a historical and theoretical context to explain the explicit and implicit meaning of the genre as it has developed, focussing in particular on their use in the UK media in late modernity. The analysis is based on the author's reflexive practice as a journalist covering crime in the national news media for 30 years and who has used mugshots to illustrate stories for their explicit and specific content. The author argues that the visual limitations of the standardised “head and shoulders” format of the mugshot make it a robust subject for analysing the changing meaning of images over time. With little variation in the image format, arguments for certain accreted layers of signification are easier to make. Within a few years of the first appearance of the mugshot form in the mid-19th century, it was adopted and adapted as a research tool by scientists and criminologists. While the positivist scientists claimed empirical objectivity we can now see that mugshots played a part in the construction of subjective notions of “the other”, “the lesser” or “sub-human” on the grounds of class, race and religion. These dehumanising ideas later informed the theorists and bureaucrats of National Socialist ideology from the 1920s to 1940s. The author concludes that once again the mugshot has become, in certain parts of the media, a signifier widely used to exclude or deride certain groups. In late modernity, the part of the media that most use mugshots – the tabloid press and increasingly tabloid TV – is part of a neo-liberal process that, in a conscious commercial appeal to the paying audience, seeks to separate rather than unify wider society

Vibrational spectroscopy: a promising approach to discriminate neurodegenerative disorders

Neurodegenerative diseases are a growing burden in modern society, thus crucially calling for the development of accurate diagnostic strategies. These diseases are currently incurable, a fact which has been attributed to their late diagnosis, after brain damage has already become widespread. An earlier and improved diagnosis is necessary for the enrolment of patients into clinical trials and can pave the way for the development of therapeutic tactics. Novel analytical techniques, such as mass spectrometry and vibrational spectroscopy, have been able to successfully detect and characterise neurodegenerative disorders. It is critical to globally support and make use of innovative basic research and techniques, which could ultimately lead to the creation of a cost-effective diagnostic test. Minimally invasive samples, such as biological fluids, have also been shown to reveal information for these diseases; utilising them could simplify sample collection/analysis and be more preferable to patients

A geometric approach to visualization of variability in functional data

We propose a new method for the construction and visualization of boxplot-type displays for functional data. We use a recent functional data analysis framework, based on a representation of functions called square-root slope functions, to decompose observed variation in functional data into three main components: amplitude, phase, and vertical translation. We then construct separate displays for each component, using the geometry and metric of each representation space, based on a novel definition of the median, the two quartiles, and extreme observations. The outlyingness of functional data is a very complex concept. Thus, we propose to identify outliers based on any of the three main components after decomposition. We provide a variety of visualization tools for the proposed boxplot-type displays including surface plots. We evaluate the proposed method using extensive simulations and then focus our attention on three real data applications including exploratory data analysis of sea surface temperature functions, electrocardiogram functions and growth curves

Cell-type specific RNA-Seq reveals novel roles and regulatory programs for terminally differentiated Dictyostelium cells

Abstract Background A major hallmark of multicellular evolution is increasing complexity by the evolution of new specialized cell types. During Dictyostelid evolution novel specialization occurred within taxon group 4. We here aim to retrace the nature and ancestry of the novel “cup” cells by comparing their transcriptome to that of other cell types. Results RNA-Seq was performed on purified mature spore, stalk and cup cells and on vegetative amoebas. Clustering and phylogenetic analyses showed that cup cells were most similar to stalk cells, suggesting that they share a common ancestor. The affinity between cup and stalk cells was also evident from promoter-reporter studies of newly identified cell-type genes, which revealed late expression in cups of many stalk genes. However, GO enrichment analysis reveal the unexpected prominence of GTPase mediated signalling in cup cells, in contrast to enrichment of autophagy and cell wall synthesis related transcripts in stalk cells. Combining the cell type RNA-Seq data with developmental expression profiles revealed complex expression dynamics in each cell type as well as genes exclusively expressed during terminal differentiation. Most notable were nine related hssA-like genes that were highly and exclusively expressed in cup cells. Conclusions This study reveals the unique transcriptomes of the mature cup, stalk and spore cells of D. discoideum and provides insight into the ancestry of cup cells and roles in signalling that were not previously realized. The data presented in this study will serve as an important resource for future studies into the regulation and evolution of cell type specialization

The participation paradigm in audience research

As today's media simultaneously converge and diverge, fusing and hybridizing across digital services and platforms, some researchers argue that audiences are dead-long live the user! But for others, it is the complex interweaving of continuities and changes that demands attention, especially now that audiencing has become a vital mode of engaging with all dimensions of daily life. This article asks how we should research audiences in a digital networked age. I argue that, while many avenues are being actively pursued, many researchers are concentrating on the notion of participation, asking, on the one hand, what modes of participation are afforded to people by the particular media and communication infrastructures which mediate social, cultural or political spheres of life? And, on the other hand, how do people engage with, accede to, negotiate or contest this as they explore and invent new ways of connecting with each other through and around media? The features of this emerging participation paradigm of audience research are examined in this article

The One with the Feminist Critique: Revisiting Millennial Postfeminism with Friends

In the aftermath of its initial broadcast run, iconic millennial sitcom Friends (NBC, 1994–2004) generated some quality scholarship interrogating its politics of gender. But as a site of analysis, it remains a curious, almost structuring absence from the central canon of the first wave of feminist criticism of postfeminist culture. This absence is curious not only considering the place of Friends at the forefront of millennial popular culture but also in light of its long-term syndication in countries across the world since that time. And it is structuring in the sense that Friends was the stage on which many of the familiar tropes of postfeminism interrogated across the body of work on it appear in retrospect to have been tried and tested. This article aims to contribute toward redressing this absence through interrogation and contextualization of the series’ negotiation of a range of structuring tropes of postfeminist media discourse, and it argues for Friends as an unacknowledged ur-text of millennial postfeminism

Bait and Snitch: Defending Computer Systems with Decoys

Threats against computer networks continue to multiply, but existing security solutions are persistently unable to keep pace with these challenges. In this paper we present a new paradigm for securing computational resources which we call decoy technology. This technique involves seeding a system with data that appears authentic but is in fact spurious. Attacks can then be detected by monitoring this phony information for access events. Decoys are capable of detecting malicious activity, such as insider and masquerade attacks, that are beyond the scope of traditional security measures. They can be used to address confidentiality breaches either proactively or after they have taken place. This work examines the challenges that must be overcome in order to successfully deploy decoys as part of a comprehensive security solution. It discusses situations where decoys are particularly useful as well as characteristics that effective decoy material should share. Furthermore, we describe the tools that we have developed to efficiently craft and distribute decoys in order to form a network of sensors that is capable of detecting adversarial action that occurs anywhere in an organizations system

Characterisation of chilean hazelnut (gevuina avellana) tissues : light microscopy and cell wall polysaccharides

By applying several differential staining techniques and light microscopy, the structure and composition of Chilean hazelnut (Gevuina avellana) seeds were analysed. The structure of the G avellana seed is very simple, with a thin, heavily lignified seed coat and two voluminous cotyledons. The embryo food reserves are uniformly distributed over the cotyledon cells. The cell wall polysaccharides were recovered from the alcohol-insoluble residue by mild treatment with warm chlorite solution and sequential extraction with alkali solutions of increasing concentration. FT-IR spectra in the 1200–850 cm-1 region were used together with chemometric techniques to distinguish the hemicellulosic and pectic polysaccharides in the extracts. The most abundant extracts were fractionated by graded precipitation in ethanol. A xyloglucan was identified by 1H and 13C NMR as the major hemicellulosic polysaccharide, with a sugar composition of 4Glc:3.5Xyl:1Gal:0.5Fuc. The hazelnut cell walls are composed of equivalent amounts of pectic polysaccharides, xyloglucans and cellulose.Fundação para a Ciência e Tecnologia (FCT) - PRAXIS XXI/BPD/18824/99.

Community Healthcare Workers (CHW) High-Risk Stabilization Study: Does the Ability of CHWs at Mobile COVID Clinics to Link patients with Uncontrolled Diabetes to a Physician Improve Short Term Outcomes?

Uncontrolled diabetes may cause preventable but significant effects. One major preventative measure is early screening; there are hopes that community healthcare workers can increase awareness and screening availability, especially in underserved populations. We hosted and recorded logs of patients at mobile COVID health clinics, educating those with uncontrolled diabetes and connecting them to healthcare. We then looked to see if any patients had improvements in blood glucose to non-diabetic levels. 378 patients were logged, but only 138 were in events that had a significant amount of repeat visits. Twenty-five of them had blood sugar indicative of uncontrolled diabetes. Out of those, there were six patients with uncontrolled diabetes and multiple visits. Four of them had improvements in blood glucose on their most recent visit, with two maintaining persistently high levels of blood glucose. While these preliminary studies show promise in the potential efficacy of CHWs in improving screening and outcomes of uncontrolled diabetes, there is a very limited sample size. Future studies should incorporate more patient logs and explore other chronic conditions commonly undiagnosed in underserved populations such as chronic kidney disease and hypertension
