Driver response time of queuing vehicles at urban signalized intersections

Driver response (reaction) time (tr) of the second queuing vehicle is generally longer than other vehicles at signalized intersections. Though this phenomenon was revealed in 1972, the above factor is still ignored in conventional departure models. This paper highlights the need for quantitative measurements and analysis of queuing vehicle performance in spontaneous discharge pattern because it can improve microsimulation. Video recording from major cities in Australia plus twenty two sets of vehicle trajectories extracted from the Next Generation Simulation (NGSIM) Peachtree Street Dataset have been analyzed to better understand queuing vehicle performance in the discharge process. Findings from this research will alleviate driver response time and also can be used for the calibration of the microscopic traffic simulation model.

Diaspora: the new philanthropy?

Diaspora philanthropy is a popular buzzword; however, what the term encompasses or how institutionalised the phenomenon is remains an open question. There are as many views and definitions of diaspora philanthropy as there are diaspora communities involved. It is often seen as a potential source of funding for geographic regions, religions or ethnic communities globally. But identifying a framework for diaspora philanthropy is difficult. Unlike the literature on international philanthropy (including ethnic philanthropy and cross-border philanthropy), which has been a predominant topic of interest in recent years, the literature on diaspora philanthropy is scarce. There is a variety of opinion on what should and should not be considered under this scribe, which makes it impossible to provide a definitive description of diaspora philanthropy that suits everyone. The term “diaspora” has different meanings for different individuals and groups of people. Some see it as relating only to exiled and ejected communities of people; others use the term to refer to individuals or groups who are living in a new homeland whether by choice or circumstance. This paper defines “diaspora” in terms of an individual or group which identifies with an original homeland, (either theirs or a member of their family’s such as a grandparent), and is in the diaspora whether through their choice or a circumstance beyond their control. This obligatory identification towards a homeland differentiates this study on diaspora philanthropy from those that define it as an affiliation with a religious community and not necessarily a specific homeland.

Preliminary Research Findings : Volunteers in Queensland State Government

As 2001 was the International Year of the Volunteer as it seemed timely to look at the legal, social and political frameworks which provide for the long term growth of volunteers. The focus of this research is on the nature and extent of volunteers in the Queensland State Government. The social capital debate (expanded by Robert Putnam in 1995) is about citizens’ participation in extracurricular activities and has been extended to mean a collective intelligence – a capacity as a people to create the society we want. The volunteer phenomenon has been used to indicate social and ethical concern.

Kiss

In an age of mobile phones, Facebook, Twitter and online dating, interactions in mediated environments often outnumber face to face encounters. Kiss is an interactive light artwork by artists Priscilla Bracks & Gavin Sade. Kiss reacts to people standing in front of the artwork looking at each other - the moment before kissing. Without interaction the work generates a seductive, ambient, red lighting display, that creates the restful sense of staring into a fire. A fleeting response of white light – like sparks flying in the air – occurs the moment before two faces touch. These sparks are visible in peripheral vision, but fade when the kissing couple turns to look at the work. This moment - as two people look at each other - is a primal moment when two people recognise each other. Face to face encounters with another person are a privileged phenomenon in which the other person's presence and proximity are strongly felt. Kiss does not respond to every instance of a kiss or a look. Its recognition algorithms are fussy, selecting some faces and not others. As in life it’s difficult to tell why sparks fly with some people but not with others. For some this will be felt as a glitch. “This machine should be part of my social life!” But it does promote trial and error, asking viewers to be intimate in public and look at each other for longer than otherwise socially normal. 10 minutes continuous eye contact is said in most cases to arouse sexual feelings in both parties. But even if we don’t look that long, a short time may be all that is needed to explore the face of the person we are looking at. We see that they are human like us. We experience beauty, difference, discomfort, perhaps even nervous laughing, before turning to a more intimate moment of recognition.

Melbourne and Brisbane: The Claims of Suburbs

This chapter critiques the imagined geography of creative cities and the creative industries, which presumes that inner cities are densely clustered hubs of urban culture and creativity while suburbs are dull, homogeneous dormitories from which creative people must escape in order to realize their potential. Drawing upon a study on creative industries workers in Melbourne and Brisbane, the authors argue that these workers are as likely to be located in the suburbs as in the inner city, and that they clearly identify advantages to being in outer suburban locations. Their findings provide a corrective to dominant urban cultural policy narratives that stress cultural amenity in the inner cities.

Renegades on the frontier of innovation: The shanzhai grassroots communities of Shenzhen in China's creative economy

Two Australian researchers specializing in China's creative industries examine recent developments in southern China commonly associated with the shanzhai phenomenon (e.g., production and sale of cheap local facsimiles of globally branded goods). While shanzhai is often condemned as the embodiment of China's "knock-off" industries, the authors argue that it might be more appropriately viewed as an instance of China's emerging creative economy and an example of rapid prototyping. The paper traces the evolution of shanzhai mobile phones and the materialization of the shanzhai ethos in popular culture. In arguing that shanzhai provides inputs into creative industries, the paper describes the fuzzy boundary between formal and informal culture and notes the interaction between three spheres of activity: official culture, the market, and grassroots culture.

The role of strategic intelligence in anticipating transnational organised crime: A literary review

Transnational Organised Crime (TOC) has become a focal point for a range of private and public stakeholders. While not a new phenomenon, the rapid expansion of TOC activities and interests, its increasingly complex structures and ability to maximise opportunity by employing new technologies at a rate impossible for law enforcement to match complicates law enforcement’s ability to develop strategies to detect, disrupt, prevent and investigate them. In an age where the role of police has morphed from simplistic response and enforcement activities to one of managing human security risk, it is argued that intelligence can be used to reduce the impact of strategic surprise from evolving criminal threats and environmental change. This review specifically focuses on research that has implications for strategic intelligence and strategy setting in a TOC context. The review findings suggest that current law enforcement intelligence literature focuses narrowly on the management concept of intelligence-led policing in a tactical, operational setting. As such the review identifies central issues surrounding strategic intelligence and highlights key questions that future research agendas must address to improve strategic intelligence outcomes, particularly in the fight against TOC.

Strolling through the (post)modern city: Modes of being a flaneur in picture books

The city and the urban condition, popular subjects of art, literature, and film, have been commonly represented as fragmented, isolating, violent, with silent crowds moving through the hustle and bustle of a noisy, polluted cityspace. Included in this diverse artistic field is children’s literature—an area of creative and critical inquiry that continues to play a central role in illuminating and shaping perceptions of the city, of city lifestyles, and of the people who traverse the urban landscape. Fiction’s textual representations of cities, its sites and sights, lifestyles and characters have drawn on traditions of realist, satirical, and fantastic writing to produce the protean urban story—utopian, dystopian, visionary, satirical—with the goal of offering an account or critique of the contemporary city and the urban condition. In writing about cities and urban life, children’s literature variously locates the child in relation to the social (urban) space. This dialogic relation between subject and social space has been at the heart of writings about/of the flâneur: a figure who experiences modes of being in the city as it transforms under the influences of modernism and postmodernism. Within this context of a changing urban ontology brought about by (post)modern styles and practices, this article examines five contemporary picture books: The Cows Are Going to Paris by David Kirby and Allen Woodman; Ooh-la-la (Max in love) by Maira Kalman; Mr Chicken Goes to Paris and Old Tom’s Holiday by Leigh Hobbs; and The Empty City by David Megarrity. I investigate the possibility of these texts reviving the act of flânerie, but in a way that enables different modes of being a flâneur, a neo-flâneur. I suggest that the neo-flâneur retains some of the characteristics of the original flâneur, but incorporates others that take account of the changes wrought by postmodernity and globalization, particularly tourism and consumption. The dual issue at the heart of the discussion is that tourism and consumption as agents of cultural globalization offer a different way of thinking about the phenomenon of flânerie. While the flâneur can be regarded as the precursor to the tourist, the discussion considers how different modes of flânerie, such as the tourist-flâneur, are an inevitable outcome of commodification of the activities that accompany strolling through the (post)modern urban space.

Damage quantification techniques in acoustic emission monitoring

Acoustic emission (AE) analysis is one of the several diagnostic techniques available nowadays for structural health monitoring (SHM) of engineering structures. Some of its advantages over other techniques include high sensitivity to crack growth and capability of monitoring a structure in real time. The phenomenon of rapid release of energy within a material by crack initiation or growth in form of stress waves is known as acoustic emission (AE). In AE technique, these stress waves are recorded by means of suitable sensors placed on the surface of a structure. Recorded signals are subsequently analysed to gather information about the nature of the source. By enabling early detection of crack growth, AE technique helps in planning timely retrofitting or other maintenance jobs or even replacement of the structure if required. In spite of being a promising tool, some challenges do still exist behind the successful application of AE technique. Large amount of data is generated during AE testing, hence effective data analysis is necessary, especially for long term monitoring uses. Appropriate analysis of AE data for quantification of damage level is an area that has received considerable attention. Various approaches available for damage quantification for severity assessment are discussed in this paper, with special focus on civil infrastructure such as bridges. One method called improved b-value analysis is used to analyse data collected from laboratory testing.

Books, toys and tablets : playing and learning in the age of digital media

Introduction During a recent study of how parents source information about children‘s early learning, one of us made our first serious foray into a local store licensed to the global chain Toys'R' Us. While walking the aisles, closely observing layout, signage and stock, several things became obvious. Firstly, large numbers of toys were labeled'educational'. Secondly, many toys in that category were intended for children under the age of two years. These were further differentiated as intended for 'babies' or 'infants', and sub-categorized on packaging or shelving using even smaller age increments (e.g. 0-3 months, 12-18 months, and so on). Thirdly, many products were labeled as 'interactive' and 'learning' toys that promised to assist children‘s early learning and development. The activation of some of these toys relied on embedded computer chip technology and promised to 'connect' children with the home television, computer and the Internet. These products were hybrids between a toy and a platform for digital media interaction. Closer inspection of toy packaging and other promotional material suggested that industry had begun to invest heavily in developing highly differentiated children‘s markets for products that yoked together concepts of learning and development, the 'fun toy' that incorporates digital technology, and offline- and online participation. In this chapter we explore the growth of this contemporary cultural phenomenon that now connects books, toys and mobile digital media with children‘s play and learning.

Perceiving and pursuing novelty : a grounded theory of adolescent creativity

Creativity plays an increasingly important role in our personal, social, educational, and community lives. For adolescents, creativity can enable self-expression, be a means of pushing boundaries, and assist learning, achievement, and completion of everyday tasks. Moreover, adolescents who demonstrate creativity can potentially enhance their capacity to face unknown future challenges, address mounting social and ecological issues in our global society, and improve their career opportunities and contribution to the economy. For these reasons, creativity is an essential capacity for young people in their present and future, and is highlighted as a priority in current educational policy nationally and internationally. Despite growing recognition of creativity’s importance and attention to creativity in research, the creative experience from the perspectives of the creators themselves and the creativity of adolescents are neglected fields of study. Hence, this research investigated adolescents’ self-reported experiences of creativity to improve understandings of their creative processes and manifestations, and how these can be supported or inhibited. Although some aspects of creativity have been extensively researched, there were no comprehensive, multidisciplinary theoretical frameworks of adolescent creativity to provide a foundation for this study. Therefore, a grounded theory methodology was adopted for the purpose of constructing a new theory to describe and explain adolescents’ creativity in a range of domains. The study’s constructivist-interpretivist perspective viewed the data and findings as interpretations of adolescents’ creative experiences, co-constructed by the participants and the researcher. The research was conducted in two academically selective high schools in Australia: one arts school, and one science, mathematics, and technology school. Twenty adolescent participants (10 from each school) were selected using theoretical sampling. Data were collected via focus groups, individual interviews, an online discussion forum, and email communications. Grounded theory methods informed a process of concurrent data collection and analysis; each iteration of analysis informed subsequent data collection. Findings portray creativity as it was perceived and experienced by participants, presented in a Grounded Theory of Adolescent Creativity. The Grounded Theory of Adolescent Creativity comprises a core category, Perceiving and Pursuing Novelty: Not the Norm, which linked all findings in the study. This core category explains how creativity involved adolescents perceiving stimuli and experiences differently, approaching tasks or life unconventionally, and pursuing novel ideas to create outcomes that are not the norm when compared with outcomes by peers. Elaboration of the core category is provided by the major categories of findings. That is, adolescent creativity entailed utilising a network of Sub-Processes of Creativity, using strategies for Managing Constraints and Challenges, and drawing on different Approaches to Creativity – adaptation, transfer, synthesis, and genesis – to apply the sub-processes and produce creative outcomes. Potentially, there were Effects of Creativity on Creators and Audiences, depending on the adolescent and the task. Three Types of Creativity were identified as the manifestations of the creative process: creative personal expression, creative boundary pushing, and creative task achievement. Interactions among adolescents’ dispositions and environments were influential in their creativity. Patterns and variations of these interactions revealed a framework of four Contexts for Creativity that offered different levels of support for creativity: high creative disposition–supportive environment; high creative disposition–inhibiting environment; low creative disposition–supportive environment; and low creative disposition–inhibiting environment. These contexts represent dimensional ranges of how dispositions and environments supported or inhibited creativity, and reveal that the optimal context for creativity differed depending on the adolescent, task, domain, and environment. This study makes four main contributions, which have methodological and theoretical implications for researchers, as well as practical implications for adolescents, parents, teachers, policy and curriculum developers, and other interested stakeholders who aim to foster the creativity of adolescents. First, this study contributes methodologically through its constructivist-interpretivist grounded theory methodology combining the grounded theory approaches of Corbin and Strauss (2008) and Charmaz (2006). Innovative data collection was also demonstrated through integration of data from online and face-to-face interactions with adolescents, within the grounded theory design. These methodological contributions have broad applicability to researchers examining complex constructs and processes, and with populations who integrate multimedia as a natural form of communication. Second, applicable to creativity in diverse domains, the Grounded Theory of Adolescent Creativity supports a hybrid view of creativity as both domain-general and domain-specific. A third major contribution was identification of a new form of creativity, educational creativity (ed-c), which categorises creativity for learning or achievement within the constraints of formal educational contexts. These theoretical contributions inform further research about creativity in different domains or multidisciplinary areas, and with populations engaged in formal education. However, the key contribution of this research is that it presents an original Theory and Model of Adolescent Creativity to explain the complex, multifaceted phenomenon of adolescents’ creative experiences.

Volunteers :what we need to find out(and why we need to do it)

Public interest in volunteering in Australia has markedly escalated over the past five years, reflected in a number of publications in the popular, professional and academic press. This interest is welcome, and in many ways, is long overdue. Volunteers, or employing a term we find more useful, voluntarism is important for a number of reasons, not least of which is its structural role in the social institutions we have developed to support people, manage dependencies and facilitate a range of developmental activities across the life span. Voluntarism is an extremely complex social phenomenon. Conceptually, it transcends the sum of its parts, in that it is more than a simple aggregation of instances of individual behaviours. Our core argument here is that this complexity is such that equally intricate and multi-faceted perspectives and models need to be employed to further our understanding. In academic speak, this means that we need to develop analytical frameworks that draw on the breadth and depth of the social sciences...

Corporate profit and impression management in developing markets

In this study, we examine how organisations in Fiji communicate or legitimise their profit. We base the need for understanding this phenomenon on the following premise. Organisations are part of a wider society, and in competition for scarce resources. Organisations obtain the rights to consume resources upon conception, but must continually legitimise their rights of existence and the need to access the resources. Legitimacy is the ability to continue to justify one’s authority to exist in a society. Organisations rights to resources are contractual, and have a moral obligation to act in a responsible manner and justify their outcomes, actions, and activities to external stakeholders. Such justifications would be an attempt at legitimizing their existence by some form of impression management. Impression management refers to the process by which individuals attempt to influence the impression of others (Melo et al. 2009). In corporate reporting, impression management occurs when management selects, display, and presents that information in a manner that distorts readers’ perceptions of corporate achievements (Neu 1991; Patten 2002), and is managed best through disclosures (O’Donovan 2002). In developing economies, there is significant Government protection that creates near-monopoly sectors and industries. The rendered protection permits organisations to provide essential services to the community at reasonable costs. Organisations in these sectors and industries have an ominous need to legitimise their position and actions. The bond between the organisations and the society is much stronger, making organisations devote more effort in communicating their activities. Protection permits organisations to make reasonable profits to sustain their operations. Society may not accept abnormal profits from operational efficiencies. Profit is fundamental to the society’s perception of an organisation, amplifying the need for the firm to justify a level of profit. Abnormal profit for organisations construes bad news, and organisations would make relevant disclosures to manage stakeholder impressions on profit (Patten 2002). Organisations can manage impressions by disclosing information in a particular way. That is, organisations would want to put the impression that the abnormal profit is justified and the society will obtain its benefits in future. Such form of impression management requires unambiguous disclosure of information. The readability of corporate disclosures is an important indicator of organisational abnormal profit-related legitimacy efforts in developing economies.

Qualitative inquiry as transformation and agency : the black sheep and workplace mobbing

This chapter discusses an action research project into the lived experience of the workplace mobbing phenomenon. The action research methodology is based on the exemplarian model (Coenen & Khonraad, 2003) from the Netherlands Group. This model requires positive outcomes for those immersed in the problem to reduce the adversity of their circumstances. The findings challenge the psychological perspective of the existing bullying literature that tends to focus on individual behaviour. This research, undertaken over a three year period with 212 participants, identified the dysfunctional nature of public sector bureaucracies and the power gained through gossip and rumour as some of the key emergent themes to explain the workplace mobbing problem. In addition, resistance, conscientisation, and agency were identified as the key to transformation for those targeted. The discussion focuses on the crystallisation phase of the exemplarian model where the participants identified themselves as the Black Sheep and adopted the motto that “a black sheep is a biting beast” (Bastard, 1565 or 6-1618, p. 90), reflecting a sense of empowerment, individual agency, and a sense of humour in dealing with the serious yet seemingly absurd reality of their situations. The identity of the Black Sheep was consolidated when the group organised a 2 day conference with over 200 attendees to discuss how best to prevent workplace mobbing. This self-affirming action was a proactive step towards metaphorically “biting back” at the problem. A number of positive outcomes were achieved including the conference with over 200 attending leading to national media coverage across Australia and additional interviews with magazines, newspapers, and radio.

Severe workplace conflict : the experience of mobbing

Workplace mobbing is a particularly serious phenomenon that is extremely costly to organizations and the health of those targeted. This article reports on a study of self-identified targets of mobbing. Findings support a five-stage process of mobbing, which commences with unresolved conflict and leads ultimately to expulsion from the organization. Participants report a number of experiences, such as lengthy investigations and escalation of conflict, that result in an increasingly unbalanced sense of power away from the individual and towards the organization. Revealed is a mismatch between the expected organizational justice processes and support and the actual experience. Recommendations for approaching this problem are discussed.
