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.

Psychological contract development: An integration of existing knowledge to form a temporal model

The psychological contract has received substantial theoretical attention over the past two decades as a popular framework within which to examine contemporary employment relationships. Previous research mostly examines breach and violation of the psychological contract and its impact on employee organization outcomes. Few studies have employed longitudinal, prospective research designs to investigate the psychological contract and as a result, psychological contract content and formation are incompletely understood. It is argued that employment relationships may be better proactively managed with greater understanding of formation and changes in the psychological contract. We examine existing psychological contract literature to identify five key factors proposed to contribute to the formation of psychological contracts. We extend the current research by integrating these factors for the first time into a temporal model of psychological contract development.

`I feel enlightened now, but...`: the limits to the pedagogic translation of critical social discourses in physical education

The emancipatory goal that underpins critical theories of teaching and learning is built on a theory of rational self-determination. In the context of physical education, critical educators believe that through a process of enlightenment teachers can recognize and transform elements of injustice and inequality that exist, albeit unwittingly, in their practice. However, despite the broad appeal of this orientation there are relatively few empirical accounts of how theories of enlightenment manifest themselves in the practice of emancipation. Propelled by the lacuna that clearly exists between critical theory and critical practice, this paper reports on the introduction of critical social discourses to a preservice PE program. It uses a case study methodology to report on two student-teachers' engagement with a range of critical social discourses during a year-long PE unit. The paper discusses some of the ways these students engaged with the theory and practice of a critical orientation for teaching and learning in physical education. Aspects of their experiences are then interpreted through Fay's (1987) critical but postmodern "limits to change" thesis. The paper concludes with tempered optimism about the potential for critical social discourses to guide preservice teachers in practical ways.

Corporate social responsibility: some key theoretical issues and concepts for new ways of doing business

This paper brings together some of the main scholarly sources and thinkers of the last fifty years or so, who have been influential in the corporate social responsibility discussions which have become important, once again, as we begin the 21st century. The author creates a narrative ofkey social, economic and political concepts and themes, which are rationalised (in ways that others might not) from what is often a very disparate, diverse and not always connected discussion on corporate social responsibility. This is not an objective history, charting the developments chronologically, but is the bringing together ofsome serious thinking in the field of corporate social responsibility in a way which has considerable resonance JOT both the development of public policy and business practice in corporate citizenship at the beginning ofthe 21st century.

Evaluating the triple bottom line in the implementation of photovoltaic systems in UK social housing

The Intergovernmental Panel on Climate Change warnings regarding the detrimental effects of carbon dioxide emissions and global warming have gained acceptance amongst many governments (IPCC 2001). The UK government has agreed to reduce emissions, implement a package of enabling measures (UKCCP 2000) and issued an Energy White Paper (HMSO 2003) calling for a diversification of energy supply policies which will include renewable sources.

Housing accounts for approximately 25% of UK CO2 emissions and as providers of social housing, Registered Social Landlords (RSLs) and their tenants are major contributors. RSLs are deliverers of national policy in several areas and contribute to the attainment of governmental environmental, social and economic targets and impact upon the wider demands of housing policy, healthcare, education and law & order (DETR 1999, Cole and Shayer 1998).

Photovoltaic (PV) electricity generation could deliver “free” electricity to the low income households historically housed by RSLs. PV helps address such issues as fuel poverty and could be used as a stimulus for creating interest in areas of low demand for social housing.

RSLs provide housing solutions which cross traditional economic, social and environmental divides and this lends their modus operandi to the concept of the triple bottom line. The triple bottom line enables social and environmental aspects to be considered alongside economic considerations within decision-making frameworks (Elkington 1999, Andreason 1995).

Using a qualitative research methodology, this paper assesses current commercial viability of PV installations on RSL developments and identifies key barriers to implementation. The paper also investigates whether the application of the triple bottom line can liberate RSLs from viewing PV as a non-viable option by enabling a greater emphasis to be placed on the social & environmental aspects of PV. The paper considers whether a framework for RSLs to improve their decision-making processes by embracing social & environmental factors is feasible.

Envisioning Indochina : the spatial and social ordering and imagining of a French colony

The emergence of Indochina in the French imagination was articulated in both representational and institutional modes. Representation involves the transmission of colonial ideals through more obtuse means; that is, through literary texts, travelogues, exhibitions, film and advertising. However, these textual sites feed from and invest in a material situation, which was the institutional arm of colonialism. Indochina was institutionally articulated in cartographic maps and surveys, in the new social spaces of cities and towns, in architectural and technological forms, through social technologies of discipline and welfare and in cultural and religious organisations. The aim of this thesis is to analyse, across a number of textual sites, the representation and institutionalisation of Otherness through the politics of space in the French colony of Indochina, Indochine in this sense becomes a spatial discourse. The French constructed a mental and physical space for Indochina by blanketing and suffocating the original cultural landscape, which in fact had to be ignored for this process to occur. What actually became manifest as a result of this projection stemmed from the French imagination. Just as the French manipulated space, language also underwent the same process of reduction. The Vietnamese script was latinised to make it more 'useable' and ‘accessible’. Through christening the union of Indochina; initiating a comprehensive writing reform; and renaming the streets in the colonial cities, the French used language us another tool for 'making transparent'. Furthermore, the colonial powers established a communication and transport network throughout the colony in an attempt to materialise their fictive (artificial) vision of a unified French Indochinese space. The accessibility and design of these different modes of transport reflected the gendered, racial and class divisions inherent in the colonial establishment. At the heart of representing and institutionalising Indochina was the desire to control and contain. This characterised French imperial ordering of space in the city and the rural areas. In rural areas land was divided into small parcels and alienated to individuals or worked into precise grids for the rubber plantation. In urban centres the native quarter was clearly demarcated from the European quarter which functioned as its modern, progressive Other. The rationale behind this segregation was premised on European, nineteenth century discourses of race, class, gender and hygiene. Influenced by Darwinian and neo-Lamarkian theories of race, this biological discourse identified the 'working class', 'women' and 'the native' as not only biologically but also culturally inferior. They were perceived as a potential, degenerative threat to the biological, cultural and industrial development of the nation. In the colonial context, space was thus ordered and domesticated to control the native population. Coextensively, the literature which springs from such a structure will be tainted by the same ideas, and thus the spaces it formulates within the readers mind feed on and reinforce this foundation. Examples of gender and indigenous narratives which contest this imaginative, transparent topography are analysed throughout this thesis. They provide instances of struggle and resistance which undermine the ideal/stereotypical level of architectural and planned space and delineate an alternative insight into colonial spatial and social relations. The fictional accounts of European women and indigenous writers both challenge and reaffirm the fixity of some of these idealised colonial boundaries. In various literary, historical, political, architectural and cinematic discourses Indochina has been und continues to be depicted as a modern city and exotic Utopia. Informed by the mood of nostalgia, exotic images of Indochina have resurfaced in contemporary French culture. France's continued desire to create, control and maintain an Indochinese space in the French public imagination reinforces the multi-layered, interconnected and persistent nature of colonial discourse.

‘We should change ourselves, but we can’t’: accounts of food and eating practices amongst British Pakistanis and Indians with type 2 diabetes

Objective(s). To look at food and eating practices from the perspectives of Pakistanis and Indians with type 2 diabetes, their perceptions of the barriers and facilitators to dietary change, and the social and cultural factors informing their accounts.

Method. Qualitative, interview study involving 23 Pakistanis and nine Indians with type 2 diabetes. Respondents were interviewed in their first language (Punjabi or English) by a bilingual researcher. Data collection and analysis took place concurrently with issues identified in early interviews being used to inform areas of investigation in later ones.

Results. Despite considerable diversity in the dietary advice received, respondents offered similar accounts of their food and eating practices following diagnosis. Most had continued to consume South Asian foods, especially in the evenings, despite their perceived concerns that these foods could be 'dangerous' and detrimental to their diabetes control. Respondents described such foods as 'strength-giving', and highlighted a cultural expectation to participate in acts of commensality with family/community members. Male respondents often reported limited input into food preparation. Many respondents attempted to balance the perceived risks of eating South Asian foodstuffs against those of alienating themselves from their culture and community by eating such foods in smaller amounts. This strategy could lead to a lack of satiation and is not recommended in current dietary guidelines.

Conclusions. Perceptions that South Asian foodstuffs necessarily comprise 'risky' options need to be tackled amongst patients and possibly their healthcare providers. To enable Indians and Pakistanis to manage their diabetes and identity simultaneously, guidelines should promote changes which work with their current food practices and preferences; specifically through lower fat recipes for commonly consumed dishes. Information and advice should be targeted at those responsible for food preparation, not just the person with diabetes. Community initiatives, emphasising the importance of healthy eating, are also needed.

Is healthy behavior contagious : associations of social norms with physical activity and healthy eating

Background
Social norms are theoretically hypothesized to influence health-related behaviors such as physical activity and eating behaviors. However, empirical evidence relating social norms to these behaviors, independently of other more commonly-investigated social constructs such as social support, is scarce and findings equivocal, perhaps due to limitations in the ways in which social norms have been conceptualized and assessed. This study investigated associations between clearly-defined social norms and a range of physical activity and eating behaviors amongst women, adjusting for the effects of social support.

Methods
Self-report survey data about particular physical activity (leisure-time moderate-vigorous activity; volitional walking; cycling for transport) and eating behaviors (fast food, soft drink and fruit and vegetable consumption), and social norms and support for these, were provided by 3,610 women aged 18-46 years living in socioeconomically disadvantaged neighborhoods in Victoria, Australia.

Results
Results of regression analyses showed that social norms for physical activity and eating behaviors predicted these respective behaviors relatively consistently; these associations generally remained significant after adjustment for social support.

Conclusions
Acknowledging the cross-sectional study design, these data confirm theoretical accounts of the importance of social norms for physical activity and eating behaviors, and suggest that this is independent from social support. Intervention strategies aimed at promoting physical activity and healthy eating could incorporate strategies aimed at modifying social norms relating to these behaviors.

Schooling and the production of social inequalities : what can and should we be doing?

To speak of an ideal is to lay claim to what ought or should be and to explain 'reality' as deviation. That is, ideals serve to provide direction towards some desired goal as well as judgment about how well a perceived reality approximates that desire. In more recent times, the postmodernist critique has provided its own 'reality check' on modernist ideals, challenging the notion that there is one best way to reach Utopian ends. The emergence of postmodern theories has signalled a general shift in 'the structure of feeling'1 from acquiescence to censure of the universal. But it is not as if there are no postmodern ideals. In these accounts, utopianism is more cogently understood as 'heterotopianisms'. While we are convinced by such critique, that there are diverse goals of value and pathways to reach them, we admit to some uneasiness about a 'postmodern pluralism' in which ideals have die potential to wash away into relativism, where one ideal is as good as the next and ways of achieving them are also equally regarded.

The politics of recognition and social justice : transforming subjectivities and new forms of resistance

Via a wide range of case studies, this book examines new forms of resistance to social injustices in contemporary Western societies. Resistance requires agency, and agency is grounded in notions of the subject and subjectivity. How do people make sense of their subjectivity as they are constructed and reconstructed within relations of power? What kinds of subjectivities are needed to struggle against forms of dominance and claim recognition? The participants in the case studies are challenging forms of dominance and subordination grounded in class, race, culture, nationality, sexuality, religion, age, disability and other forms of social division. It is a premise of this book that new and/or reconstructed forms of subjectivity are required to challenge social relations of subordination and domination. Thus, the transformation of subjectivity as well as the restructuring of oppressive power relations is necessary to achieve social justice. By examining the construction of subjectivity of particular groups through an intersectional lens, the book aims to contribute to theoretical accounts of how subjects are constituted and how they can develop a critical distance from their positioning.

Characterizing university library use of social media: a case study of twitter and facebook from Australia

The work presented here characterise the engagement of one university library with two social media platforms popular with academic libraries. The collected data are analysed to identify the forms of Twitter and Facebook activity that engage library stakeholders in social media conversations. Associations were observed between: i) directed tweets from the library and mentions of the library by others on Twitter; and ii) comments from the library and comments from others on Facebook. Three broad classes of Twitter user interacting with the library were revealed: i) accounts strongly linked to the library with multiple to/from tweets; ii) those weakly linked to the library with, typically, a single tweet; and iii) those indirectly linked to the library through tweets mentioning the library and sent by other users. Two divergent forms of Facebook interaction with the library were highlighted: i) a library post generating a large sequence of comments, typically in response to a competition/challenge and ii) a library post with no comments, typically a photo post or a post inviting readers to click a link to find out more about an event/service. The work presented here is an initial investigation that provides useful insights, and offers a methodology for future research.

Direct perception, inter-subjectivity and social cognition: why phenomenology is a necessary but not sufficient condition

In this paper I argue that many of the core phenomenological insights, including the emphasis on direct perception, are a necessary but not sufficient condition for an adequate account of inter-subjectivity today. I take it that an adequate account of inter-subjectivity must involve substantial interaction with empirical studies, notwithstanding the putative methodological differences between phenomenological description and scientific explanation. As such, I will need to explicate what kind of phenomenology survives, and indeed, thrives, in a milieu that necessitates engagement with the relevant sciences, albeit not necessarily deference to them. There will be two central aims to this paper: 1. to defend the centrality and vitality of phenomenological treatments of inter-subjectivity via a consideration of some remarks in Sartre - which I do think possess a non-trivial unity amongst the various interlocutors - and the manner in which they in fact serve to provide the basis for a better explanation of an array of empirical data than existing inferentialist or mindreading accounts of social cognition (notably Theory Theory, Simulation Theory, and hybrid versions); 2. to offer the methodological resources for renewing phenomenology in a manner that acknowledges ostensibly non-phenomenological moments in theory production - which involve explanation, inference to the best explanation, etc. - but does not abandon phenomenology for all that, allowing it to be simply absorbed into empirical explanation or other forms of philosophical analysis without remainder.

Guidelines for teachers to elicit detailed and accurate narrative accounts from children

This paper provides interview strategies for teachers who talk to children about serious events, including bullying, truancy, and suspected maltreatment. With regard to the latter, teachers are among the largest group of professionals reporting child abuse, but also tend to evince low substantiation rates. We review research on best practice interviewing, with a focus on its application in school settings. Interview phases are described chronologically, with interview excerpts included for illustrative purposes. Gaps in knowledge about the appropriateness of techniques are highlighted, and recommendations for future research specifically within the school setting are made. It is proposed that teachers receive basic training in best practice interviewing so that, when required, they can confidently ask about difficulties in children's lives while minimizing the potential for contamination of children's responses.
