Position paper on the future of social networking

Social networking mediated by web sites is a relatively new phenomenon and as with all technological innovations there continues to be a period of both technical and social adjustment to fit the services in with people’s behaviours, and for people to adjust their practices in the light of the affordances provided by the technology. Social networking benefits strongly from large scale availability. Users gain greater benefit from social networking services when more of their friends are using them.This applies in social terms, but also in eLearning and professional networks. The network effect provides one explanation for the popularity of internet based social networking sites (SNS) because the number of connections between people which can be maintained by using them is greatly increased in comparison to the networks available before the internet. The ability of users to determine how much they trust information available to them from contacts within their social network is important in almost all modes of use. As sources of information on a range of topics from academic to shopping advice, the level of trust which a user can put in other nodes is a key aspect of the utility of the system.

Social approach in preschool children with Williams syndrome: the role of the face

Background Indiscriminate social approach behaviour is a salient aspect of the Williams syndrome (WS) behavioural phenotype. The present study examines approach behaviour in preschoolers with WS and evaluates the role of the face in WS social approach behaviour. Method Ten preschoolers with WS (aged 3-6 years) and two groups of typically developing children, matched to the WS group on chronological or mental age, participated in an observed play session. The play session incorporated social and non-social components including two components that assessed approach behaviour towards strangers, one in which the stranger’s face could be seen and one in which the stranger’s face was covered. Results In response to the non-social aspects of the play session, the WS group behaved similarly to both control groups. In contrast, the preschoolers with WS were significantly more willing than either control group to engage with a stranger, even when the stranger’s face could not be seen. Conclusion The findings challenge the hypothesis that an unusual attraction to the face directly motivates social approach behaviour in individuals with WS.

Social equality in the number of choice options is represented in the ventromedial prefrontal cortex

A distinct aspect of the sense of fairness in humans is that we care not only about equality in material rewards but also about equality in non-material values. One such value is the opportunity to choose freely among many options, often regarded as a fundamental right to economic freedom. In modern developed societies, equal opportunities in work, living, and lifestyle are enforced by anti-discrimination laws. Despite the widespread endorsement of equal opportunity, no studies have explored how people assign value to it. We used functional magnetic resonance imaging to identify the neural substrates for subjective valuation of equality in choice opportunity. Participants performed a two-person choice task in which the number of choices available was varied across trials independently of choice outcomes. By using this procedure, we manipulated the degree of equality in choice opportunity between players and dissociated it from the value of reward outcomes and their equality. We found that activation in the ventromedial prefrontal cortex tracked the degree to which the number of options between the two players was equal. In contrast, activation in the ventral striatum tracked the number of options available to participants themselves but not the equality between players. Our results demonstrate that the vmPFC, a key brain region previously implicated in the processing of social values, is also involved in valuation of equality in choice opportunity between individuals. These findings may provide valuable insight into the human ability to value equal opportunity, a characteristic long emphasized in politics, economics, and philosophy.

Oxytocin increases eye contact during a real-time, naturalistic social interaction in males with and without autism

Autism spectrum conditions (autism) affect ~1% of the population and are characterized by deficits in social communication. Oxytocin has been widely reported to affect social-communicative function and its neural underpinnings. Here we report the first evidence that intranasal oxytocin administration improves a core problem that individuals with autism have in using eye contact appropriately in real-world social settings. A randomized double-blind, placebo-controlled, within-subjects design is used to examine how intranasal administration of 24 IU of oxytocin affects gaze behavior for 32 adult males with autism and 34 controls in a real-time interaction with a researcher. This interactive paradigm bypasses many of the limitations encountered with conventional static or computer-based stimuli. Eye movements are recorded using eye tracking, providing an objective measurement of looking patterns. The measure is shown to be sensitive to the reduced eye contact commonly reported in autism, with the autism group spending less time looking to the eye region of the face than controls. Oxytocin administration selectively enhanced gaze to the eyes in both the autism and control groups (transformed mean eye-fixation difference per second=0.082; 95% CI:0.025–0.14, P=0.006). Within the autism group, oxytocin has the most effect on fixation duration in individuals with impaired levels of eye contact at baseline (Cohen’s d=0.86). These findings demonstrate that the potential benefits of oxytocin in autism extend to a real-time interaction, providing evidence of a therapeutic effect in a key aspect of social communication.

Transport of animals between rooms: A little-noted aspect of laboratory procedure that may interfere with memory

This study investigated the effects of transporting animals from the experimental room to the animal facility in between experimental sessions, a procedure routinely employed in experimental research, on long-term social recognition memory. By using the intruder-resident paradigm, independent groups of Wistar rats exposed to a 2-h encounter with an adult intruder were transported from the experimental room to the animal facility either 0.5 or 6h after the encounter. The following day, residents were exposed to a second encounter with either the same or a different (unfamiliar) intruder. Resident`s social and non-social behaviors were carefully scored and subjected to Principal Component Analysis, thus allowing to parcel out variance and relatedness among these behaviors. Resident rats transported 6h after the first encounter exhibited reduced amount of social investigation towards familiar intruders, but an increase of social investigation when exposed to a different intruder as compared to the first encounter. These effects revealed a consistent long-lasting (24h) social recognition memory in rats. In contrast, resident rats transported 0.5 h after the first encounter did not exhibit social recognition memory. These results indicate that this common, little-noted, laboratory procedure disturbs long-term social recognition memory. (C) 2011 Elsevier B.V. All rights reserved.

Social presence online: networking learners at a distance

This paper draws on two studies which researched the use of online small group environments where collaborative learning is a central structure for learning. The establishment of social presence is facilitated through the socio-affective aspect of small group interaction which contributed to the effectiveness of learning online. Social presence, the ability of online learners to project themselves into a textual environment which has few visual or contextual cues, will be explored as an important element in facilitating effective online learning. The teacher's role in helping students project their online social presence and in establishing an environment for learning within the larger group computer conference will also be discussed.

Competing on the higher ground : social expectations and sport

Research in sport ethics has traditionally focused on the ethical dimensions of the sport event and athletes, however the examination of the principles of ethics to the management and organisation of sport is a relatively recent phenomenon. The tension between the roles and responsibilities of sport as a business, and sport as an ethical and moral aspect of society has forced sport organisations to face an increased number of complex ethical dilemmas. As sport systems throughout the world become further professionalised and bureaucratised, the community understanding of what is ‘good’ is challenged. It is a commonly held expectation that there should be a high level of moral behaviour from those participating directly in the sport event (athletes, coaches, referees), however this expectation has extended to the sporting clubs and organisations which govern the sport itself.

Often used interchangeably, ethics and morality are complex terms concentrating on issues of right and wrong behaviour. Beauchamp and Bowie (1993) stated that the term morality suggests a social institution, composed of a set of standards which are pervasively acknowledged by the members of a culture, or alternatively a social construction. The application of ethics and moral values to the business environment applies across all sectors, including for-profit, non-profit and government, however Rubin (1990) found that the normative ethics, those which society accepts as ethical behaviour, varies from sector to sector. In the non-profit sector, to which many sport organisations belong, Rubin (1990) found that because the community expects more ‘good’, they accept less ‘bad’. As many sport organisations throughout the world remain largely non-profit, linked with the commonly held belief that sport is a foundation for moral behaviours, the idealistic expectation of ethical conduct placed upon them may be different to those of more mainstream business organisations.

Mewett (2003) noted the importance of sport as a social phenomenon which ramifies widely through society to become an intrinsic part of culture and community life. The different expectations of ethical conduct and moral value placed on sport organisations increases the public interest in the ethical dilemmas faced by these organisations. Using the concept of conflict of interest as an example, this paper will examine the tension and difference between the community and social understanding and expectations of sport, and those of the sport organisations themselves.

Social work and spirituality in a secular society

• Summary: In an increasingly secular era which finds only a small minority of the population regularly participating in organized religion, there is emerging interest in how spirituality can be incorporated into social work practice. This article proposes one way in which this might occur in `deliberately secular' nations such as Australia.

• Findings: A framework in which spirituality is considered to be an aspect of lived experience is proposed. Dimensions of life which can be incorporated into such a framework include life rituals, creativity, social action, and sense of place.

• Applications : Conceptualizing spirituality in a way which does not use specifically religious language or concepts, may enable discussion of spiritual issues to be incorporated into social work practice when either practitioners or service users have or no religious background or affiliation or no shared religious background.

The right to an impartial hearing trumps the social imperative of bringing accused to trial even 'down under'

Accused persons who are subjected to a saturation level of negative media coverage may be denied an impartial hearing, which is perhaps the most important aspect of the right to a fair hearing. Despite this, the courts have generally held that the social imperative of prosecuting accused trumps the interests of the accused. The justification for an impartial hearing stems from the repugnance of convicting the innocent. Viewed dispassionately, this imperative is not absolute, given that every legal system condones procedures which result in the conviction of some innocent people. While the importance of guarding against wrongful convictions has been overstated, the imperative to bring to trial all accused has been even more exaggerated. The legal system has displayed a capacity to deal with cases where the guilty walk free. The institutional integrity of the criminal justice system would be significantly compromised by convictions that are tarnished by pre-judgment. Confidence in the criminal justice system is more important than individual criminal accountability. The inability to receive an impartial hearing should result in a permanent stay. The only exception is where the alleged crime has the capacity to cause widespread fear or social unrest. This only applies in relation to serious acts of terrorism. This article focuses on recent legal fair trial developments in Australia, however, the analysis, reasoning and conclusion applies in relation to all jurisdictions where juries determine guilt and innocence.

How social is the virtual design studio? A case study of a third year design studio

With the advent of social networks, it became apparent that the social aspect of designing and learning plays a crucial role in students’ education. Technologies and skills are the base on which learners interact. The ease of communication, leadership opportunity, democratic interaction, teamwork, and the sense of community are some of the aspects that are now in the centre of design interaction. The paper examines Virtual Design Studios (VDS) that used media-rich platforms and analyses the influence the social aspect plays in solving all problems on the sample of a design studio at Deakin University. It studies the effectiveness of the generated social intelligence and explores the facilitation of students’ self-directed learning. Hereby the paper studies the construction of knowledge via social interaction and how blended learning environments foster motivation and information exchange. It presents its finding based on VDS that were held over the past three years.

Virtual design studio via social networks

With the advent of social networks, it became apparent that the social aspect of designing and learning plays a crucial role in students’ education. The ease of communication, leadership opportunity, democratic interaction, teamwork, and the sense of community are some of the aspects that are now in the centre of design interaction. Online interactions, multimedia, mobile computing and face-to-face learning create blended learning environments to which some Virtual Design Studios (VDS) have reacted. On the sample of a design studio at Deakin University the paper discusses details of the Social Network VDS, its pedagogical implications to PBL, and presents how it is successful in empowering architectural students to collaborate and communicate design proposals that integrate a variety of skills, deep learning, and construction of knowledge. It studies the effectiveness of the generated social intelligence and explores the facilitation of students’ self-directed learning. Hereby the paper studies the construction of knowledge via social interaction and how blended learning environments foster motivation and information exchange.

A sentiment-aware approach to community formation in social media

Participating in a community exemplifies the aspect of sharing, networking and interacting in a social media system. There has been extensive work on characterising on-line communities by their contents and tags using topic modelling tools. However, the role of sentiment and mood has not been studied. Arguably, mood is an integral feature of a text, and becomes more significant in the context of social media: two communities might discuss precisely the same topics, yet within an entirely different atmosphere. Such sentiment-related distinctions are important for many kinds of analysis and applications, such as community recommendation. We present a novel approach to identification of latent hyper-groups in social communities based on users’ sentiment. The results show that a sentiment-based approach can yield useful insights into community formation and metacommunities, having potential applications in, for example, mental health—by targeting support or surveillance to communities with negative mood—or in marketing—by targeting customer communities having the same sentiment on similar topics.

Online social capital : mood, topical and psycholinguistic analysis

Social media provides rich sources of personal information and community interaction which can be linked to aspect of mental health. In this paper we investigate manifest properties of textual messages, including latent topics, psycholinguistic features, and authors' mood, of a large corpus of blog posts, to analyze the aspect of social capital in social media communities. Using data collected from Live Journal, we find that bloggers with lower social capital have fewer positive moods and more negative moods than those with higher social capital. It is also found that people with low social capital have more random mood swings over time than the people with high social capital. Significant differences are found between low and high social capital groups when characterized by a set of latent topics and psycholinguistic features derived from blogposts, suggesting discriminative features, proved to be useful for classification tasks. Good prediction is achieved when classifying among social capital groups using topic and linguistic features, with linguistic features are found to have greater predictive power than latent topics. The significance of our work lies in the importance of online social capital to potential construction of automatic healthcare monitoring systems. We further establish the link between mood and social capital in online communities, suggesting the foundation of new systems to monitor online mental well-being.

The influence of faith-based organisations on Australian social policy

This historical overview explores the crucial and changing relationships between faith-based organisations and governments, not only in the implementation of social services but also in the formation of social policy. Historically Australian governments have left large areas of social provision to the non-government sector. For example, income support for the unemployed was not taken up by governments until World War II and income support for sole parents remained largely a responsibility for non-government organisations (NGOs) until the 1970s. Prior to governments taking responsibility for income support, most of these NGOs were religious organisations surviving on donations, philanthropic support and limited government funding. It is argued that the dominant, semi-public role of religious organisations in service delivery and social policy formation is an important but largely overlooked aspect of the Australian historical experience.

Violence and xenophobia as means of social control in times of collapse: the soviet occupation of post-war Germany, 1945-1947

This article explores an overlooked aspect of the Soviet occupation of post-war Germany, namely, the influence of wartime violence on German behavioural patterns during the post-war period. Whilst many historians have noted that violent Soviet conduct in Germany merely encouraged the intensification of existing anti-Soviet attitudes therein, few have attempted to thoroughly investigate its influence on German behaviour. The conclusions made by those few historians who have done so are unsupported by the Soviet archival evidence drawn upon in the article. Using this evidence, the article highlights the tentative links between the violent repression of an occupation force and the muted responses of its subjects. It concludes that the nature of the repression and of the broader occupation landscape in which it developed, was integral in ensuring that the characteristically docile behaviour of the German population toward the Soviet occupier continued unabated throughout much of the occupation period.
