Identity and self-presentation : from a representational to a performative lens in studying social media engagement in organisations

Social media make fast inroads into organisations. This raises issues regarding self-presentation and locating experts in these new emerging communication spaces, as the basis for effective social media-enabled knowledge work. However, research on self-presentation and identity in organisational social media is only just emerging and has been founded on broader understandings from studies of public social media. In this literature study we demonstrate that the existing body of research on identity in social media is dominated by a ‘representational lens’. Based on an analysis of the historic foundations of this stream of research, we will expose limitations of this lens in capturing contemporary engagement in online spaces and advocate for a ‘performative lens’ in studying identity work in organisations. We contribute a detailed exposition of the evolution of identity studies in the context of public social media, and we offer an alternative lens for studying the topic in organisational contexts.

Teaching primary science : emotions, identity and the use of practical activities

This paper uses cultural historical activity theory to examine the interactions between the choices primary teachers make in the use of practical activities in their teaching of science and the purposes they attribute to these; their emotions, background and beliefs; and the construction of their identities as teachers of science. It draws on four case studies of science lessons taught over a term by four exemplary teachers of primary science. The data collected includes video recordings of science lessons, interviews with each teacher and some of their students, student work, teachers’ planning documents and observation notes. In this paper, we examine the reflexive relationship between emotion and identity, and the teachers’ objectives for their students’ learning; the purposes (scientific and social) the teachers attributed to practical activities; and the ways in which the teachers incorporated practical activities into their lessons. The findings suggest that it is not enough to address content knowledge, pedagogy and pedagogical content knowledge in teacher education, but that efforts also need to be made to influence prospective primary teachers’ identities as scientific thinkers and their emotional commitment to their students’ learning of science.

Bloods, Crips and Southern Cross Soldiers: we are all gangbangers now!

This paper presents findings from the author's PhD thesis exploring violent youth subcultures in Australia. It addresses whether growing uncertainties around issues of cultural identity and belonging in an era of risk has produced more defensive models of DIY youth culture at a local scale. Theoretically, the author examines whether globalisation has unsettled normative youth subject positions associated with the nation-state, problematising conventional logics of youth cultural formation (i.e. which view questions of race and racism through a white/black, mainstream/subculture binary). As Beck (1992;1999) argues, the de-bounding influence of globalisation has led to an ambivalent set of relations where forms of youth identity have become freed from the nation-state and class based forms of community and must be self-organised. In particular, he argues that this has produced cosmopolitan subjects and social movements as well as ‘counter-modern’ subjects and cultures. This paper applies Beck’s theories alongside theories focused on global/local influences on youth culture to an ethnographic study of two violent youth subcultures in Australia, these being the white ‘patriotic’ youth formation which emerged in the Cronulla riots and youth gang formations in Melbourne’s western suburbs. In doing so the author examines the extent to which violent youth subcultures in Australia can be regarded as strategic responses intended to restore forms of collective cultural belonging at a local scale vis a vis ‘the global’ and its destabilizing influences.

Will it be me? Identity, concern, and perspective

Self-reflexive or egocentric concern has been taken to present a serious problem for reductionist and eliminativist metaphysical accounts of personal identity. Philosophers have tended to respond in one of three ways: by continuing the search for a metaphysical account of identity that (prudentially if not morally) justifies egocentric concern; by accepting that egocentric concern can hold between persons who are not numerically identical; or by advocating the abandonment of egocentric concern altogether. All these approaches, however, distinguish between metaphysical ‘facts’ and affective responses to them. Exploring a well-known example from Bernard Williams, I argue that egocentric concern presents itself as irreducibly first-personal and as making its own set of numerical personal identity claims on the phenomenal level. Williams' example also points to the need to complicate the first/third person schema by factoring in a further distinction between present-tense and implicitly atemporal perspectives on the self. Once this move is made, we can see that the identity claims figured in first-person present-tense experience and those arrived at through metaphysical deliberation need to be distinguished. We should resist the temptation to privilege one perspective over the other in all instances, or to collapse them into a unitary account of selfhood.

Recognising user identity in twitter social networks via text mining

Social networks have become a convenient and effective means of communication in recent years. Many people use social networks to communicate, lead, and manage activities, and express their opinions in supporting or opposing different causes. This has brought forward the issue of verifying the owners of social accounts, in order to eliminate the effect of any fake accounts on the people. This study aims to authenticate the genuine accounts versus fake account using writeprint, which is the writing style biometric. We first extract a set of features using text mining techniques. Then, training of a supervised machine learning algorithm to build the knowledge base is conducted. The recognition procedure starts by extracting the relevant features and then measuring the similarity of the feature vector with respect to all feature vectors in the knowledge base. Then, the most similar vector is identified as the verified account.

Modelling daylight for preserving identity : simulation of daylight levels for successful intervention in historic buildings

Historical listed buildings have their own unique cultural identity, which is one of the criteria used by decision mechanisms for their statutory protection. The identity of many of these buildings is often related to their tangible features/components, such as period characteristics (geometry, size, colour, form, and shape), materials and construction. Daylight is one of the in/tangible elements that have contributed to the distinctiveness of many historical buildings, yet when constructing preservation schemes of historical buildings, daylight is rarely introduced or considered as one of the components that shape the character of buildings. One of the reasons is the limited number of credible simulation studies that identify such interrelationships. As many of these buildings were originally designed to accommodate different activities to today's requirements, maintaining the quality of daylight that originally contributed to their visual identity can be a very challenging task, especially if the building is to be adapted to accommodate a different activity. In this paper we will discuss the conflict between maintaining the original visual identity of historical buildings and meeting the visual requirements of restored buildings. The paper discusses the visual performance of a traditional bathhouse (Hammam) in the city of Bursa in Turkey. The change in the visual performance of the selected case study will be discussed in terms of daylight conditions. The paper explores the possibility of maintaining the original daylight conditions of renovated historical buildings while meeting the visual requirements of the new use.

Interviewing pairs: discussions on migration and identity

This article examines a research method of conducting interviews with pairs of individuals, who may be friends or relatives. The authors critically reflect on their experiences of collecting qualitative data in an interview with two respondents. While one-on-one interviews and focus groups are more established and well-studied forms of gathering research data, we argue that paired interviews as a data collections method present additional advantages as well as some challenges for qualitative researchers. The researchers embraced the opportunity to interview pairs of individuals with the intention of minimising the asymmetry of power habitually inherent in interview situations. In the authors' experiences, paired interviews served to empower those being interviewed and reduced the discomfort felt by some in the personal interview situation. This form of interviewing tended to give more autonomy to the respondents and prompted them to provide more nuanced responses. Paired interviews assisted respondents in feeling relaxed and comfortable, provided a vibrant environment that encouraged respondents to build on each other's ideas and enabled them to enhance each other's stories. Respondents were better motivated to build discussions around an interview question and then illustrate their responses with examples. In our studies, we found that our respondents tended to offer more thorough and comprehensive narratives in the setting of a paired interview.

Locke, Kierkegaard, and the phenomenology of personal identity

Personal Identity theorists as diverse as Derek Parfit, Marya Schechtman and Galen Strawson have noted that the experiencing subject (the locus of present psychological experience) and the person (a human being with a career/narrative extended across time) are not necessarily coextensive. Accordingly, we can become psychologically alienated from, and fail to experience a sense of identity with, the person we once were or will be. This presents serious problems for Locke’s original account of “sameness of consciousness” constituting personal identity, given the distinctly normative (and indeed eschatological) focus of his discussion. To succeed, the Lockean project needs to identify some phenomenal property of experience that can constitute a sense of identity with the self figured in all moments to which consciousness can be extended. I draw upon key themes in Kierkegaard’s phenomenology of moral imagination to show that Kierkegaard describes a phenomenal quality of experience that unites the experiencing subject with its past and future, regardless of facts about psychological change across time. Yet Kierkegaard’s account is fully normative, recasting affective identification with past/future selves as a moral task rather than something merely psychologically desirable (Schechtman) or utterly contingent (Parfit, Strawson).

Efficient escrow-free identity-based signature

The notion of identity-based signature scheme (IBS) has been proven useful in some scenarios where relying on the validity of the certificates is impractical. Nevertheless, one remaining inherent problem that hinders the adoption of this cryptographic primitive in practice is due to the key escrow problem, where the private key generator (PKG) can always impersonate the user in the system. In 2010, Yuen et al. proposed the notion of IBS that does not suffer from the key escrow problem. Nevertheless, their approach relies on the judge who will later blame the malicious PKG when such a dispute occurs, assuming that the PKG is willing to collaborate. Although the approach is attractive, but unfortunately it is impractical since the malicious PKG may just refuse to collaborate when such an incident happens. In this paper, we propose a new escrow-free IBS, which enjoys three main advantages, namely key escrow free, practical and very efficient. We present a generic intuition as well as an efficient instantiation. In our approach, there is no judge involvement required, as the public can determine the malicious behaviour of PKG when such an incident happens. Further, the signature size of our instantiation is only two group elements, which outperforms the existing constructions in the literature.

Mothering siblings: Diaspora, desire and identity in American born confused Desi

In this essay we consider the construction of cultural identity, motherhood and the family in ABCD, a film of the Indian diaspora that had its world premiere at the 2001 London Film Festival. This film reads family, apparently within familiar narrative structures such as the U.S.-immigrant story, as portrayed in films like Goodbye, Columbus and My Big Fat Greek Wedding, and the "leaving home" story, as classically portrayed in Pride and Prejudice, where a young person needs to escape from her clueless family. The irritating presence of the mother in the film, and the quickness with which her two children appear to make life-determining decisions following her death, seem to invite discussions of plot and character organized around ideas of individual development, self-improvement and understanding. This is the territory of the desire plot, an account of family history captured for the twentieth century by Freudian-Lacanian readings which position sexual desire within the unconscious history of familial fantasies, understood as vertical and Oedipal. In this territory, mothers and old ladies become, as Mary Jacobus memorably phrased it, little more than "the waste products" of a system in which marriageable women are objects of exchange between men (142) and a mother's death would be expected to grease the wheels of narrative. Identity and narrative are inextricably linked here: a certain understanding of narrative as developmental and teleological paves the way for an understanding of identity as either/or. There are problems, however, in trying to read ABCD as a bildüngsroman structured by what Susan Freidman calls "the temporal plots of the family romance, its repetitions and discontents" (137), rendering the "Indian" characteristics of the plot unreadable, and the apparently self-defeating nature of the characters' choices and behavior, rather pointless. A central [End Page 16] difficulty is that the film both responds to and resists readings based on the Oedipal model of the bildüngsroman with its focus on linear development through time.

Short designated verifier signature scheme and its identity-based variant

The notion of strong designated verifier signature was put forth by Jakobsson, Sako and Impagliazzo in 1996, but the formal definition was defined recently by Saeednia, Kremer and Markowitch in 2003 and revisited by Laguil- laumie and Vergnaud in 2004. In this paper, we firstly propose the notion of short strong designated verifier sig- nature scheme, and extend it to the short identity-based strong designated verifier scheme. Then, we propose the first construction of short strong designated verifier sig- nature scheme. We also extend our scheme to construct a short identity-based strong designated verifier signature scheme. The size of the signature of our schemes is the shortest compared to any existing schemes reported in the literature. We provide formal security proofs for our schemes based on the random oracle model. Finally, we also discuss an extension of our scheme to construct a short strong designated verifier signature without random oracle.

What about us? We have careers too! The career experiences of Australian sport scientists

 he professionalisation of sport has provided career opportunities for athletes, coaches and sport scientists alike. The career development literature for athletes is well established and the empirical career literature for coaches is growing, but little is known about the careers of sport scientists. The purpose of this investigation was to explore and examine the career experiences of Australian sport scientists. In-depth interviews were conducted with six practicing Australian sport scientists at different career stages. Several themes emerged from the data on careers of sport scientists that are unique to sport. Sport scientists identify strongly with their role in sport success and yet they receive little recognition for what they do. All participants experienced career dissonance as they transitioned from practitioner to another career such as academia or sport management. Feelings of loss were identified by participants as their applied work diminished when they moved away from their early career service roles. All six participants believed that in order to advance their career in sport their options were moving overseas, working in academia, or retraining for a career in sports management. It is recommended that sport scientists be provided with better career education and more structured professional development.

Monitoring persona: mediatized identity and the edited public self

One of the key transformations in contemporary culture is the insistent demand to construct a public persona. Constructing a persona for navigating through life is not new; what is new is the naturalization of producing a mediatized version of this public self. The complexity of producing an online public identity involves the labour of monitoring and editing ourselves, connecting with strategic purpose to others and building recognizable reputations. This article both identifies and concludes that what we are experiencing is the work and relative value of producing a mediatized identity—a persona—which is a form of identity often linked to celebrities in our traditional media industries and now pandemic in contemporary culture.

Cancer risk factors, diagnosis and sexual identity in the Australian longitudinal study of women's health

PURPOSE: We sought to examine cancer diagnosis, cancer treatment, and related risk factors among Australian, middle-aged, exclusively heterosexual women compared with sexual minority women (SMW; mainly heterosexual, bisexual, mainly lesbian, and lesbian). METHODS: Secondary data analysis of the Australian Longitudinal Study of Women's Health for women born in 1946 through 1951 (n = 10,451) included bivariate tests (i.e., contingency table analyses, independent t tests). RESULTS: SMW did not have significantly higher cancer diagnoses compared with exclusively heterosexual women, although they were more likely to report never having had a mammogram or pap smear. SMW were also significantly more likely to be high-risk drinkers (11.1% vs. 6.8%; p < .05), current smokers (15.1% vs. 8.3%; p < .001), report significantly higher rates of depression (mean ± SD; 6.4 ± 5.5 vs. 5.4 ± 5.1; p < .01.), have experienced physical abuse (10.2% vs. 5.1%; p < .001), and been in a violent relationship (27.2% vs. 12.8%; p < .001). CONCLUSION: SMW had higher rates of several known cancer risk factors, ostensibly placing them at higher risk of cancer as well as chronic health conditions. Further research is needed to determine whether increased risk results in increased cancer as these women age, and to inform the development of interventions to reduce the risk of disease for SMW.

How reliable is internet-based self-reported identity, socio-demographic and obesity measures in European adults?

In e-health intervention studies, there are concerns about the reliability of internet-based, self-reported (SR) data and about the potential for identity fraud. This study introduced and tested a novel procedure for assessing the validity of internet-based, SR identity and validated anthropometric and demographic data via measurements performed face-to-face in a validation study (VS). Participants (n = 140) from seven European countries, participating in the Food4Me intervention study which aimed to test the efficacy of personalised nutrition approaches delivered via the internet, were invited to take part in the VS. Participants visited a research centre in each country within 2 weeks of providing SR data via the internet. Participants received detailed instructions on how to perform each measurement. Individual's identity was checked visually and by repeated collection and analysis of buccal cell DNA for 33 genetic variants. Validation of identity using genomic information showed perfect concordance between SR and VS. Similar results were found for demographic data (age and sex verification). We observed strong intra-class correlation coefficients between SR and VS for anthropometric data (height 0.990, weight 0.994 and BMI 0.983). However, internet-based SR weight was under-reported (Δ -0.70 kg [-3.6 to 2.1], p < 0.0001) and, therefore, BMI was lower for SR data (Δ -0.29 kg m(-2) [-1.5 to 1.0], p < 0.0001). BMI classification was correct in 93 % of cases. We demonstrate the utility of genotype information for detection of possible identity fraud in e-health studies and confirm the reliability of internet-based, SR anthropometric and demographic data collected in the Food4Me study.
