Distinguishing consumers' need for uniqueness from individuation and general need for uniqueness

This paper describes the results of five previously unpublished studies designed to investigate the distinctiveness of consumers' need for uniqueness scale (CNFU) from two competing predictors of differentiating behaviors from the psychological literature - individuation and general need for uniqueness. Consumers' need for uniqueness is defined as the trait of pursuing differentness relative to others through the acquisition, utilization, and disposition of consumer goods for the purpose of developing and enhancing one's self-image and social image. As such, the research offers additional evidence from an extensive program of research regarding the validity of the consumer need for uniqueness scale developed by Tepper, Bearden and Hunter (2000). Specifically, the results of the studies demonstrate that the scale operates distinctively through counterconformity motivation as hypothesized and moderates the effects of situational variables on preferences for differentiating consumer offerings as expected.

The Sophists (Ancient Greek)

The sophists were itinerant professional teachers and intellectuals who frequented Athens and other Greek cities in the second half of the fifth century B.C.E. In return for a fee, the sophists offered young wealthy Greek men an education in aretē (virtue or excellence), thereby attaining wealth and fame while also arousing significant antipathy. Prior to the fifth century B.C.E., aretē was predominately associated with aristocratic warrior virtues such as courage and physical strength. In democratic Athens of the latter fifth century B.C.E., however, aretē was increasingly understood in terms of the ability to influence one’s fellow citizens in political gatherings through rhetorical persuasion; the sophistic education both grew out of and exploited this shift. The most famous representatives of the sophistic movement are Protagoras, Gorgias, Antiphon, Hippias, Prodicus and Thrasymachus.

The historical and philological difficulties confronting an interpretation of the sophists are significant. Only a handful of sophistic texts have survived and most of what we know of the sophists is drawn from second-hand testimony, fragments and the generally hostile depiction of them in Plato’s dialogues.

The philosophical problem of the nature of sophistry is arguably even more formidable. Due in large part to the influence of Plato and Aristotle, the term sophistry has come to signify the deliberate use of fallacious reasoning, intellectual charlatanism and moral unscrupulousness. It is, as the article explains, an oversimplification to think of the historical sophists in these terms because they made genuine and original contributions to Western thought. Plato and Aristotle nonetheless established their view of what constitutes legitimate philosophy in part by distinguishing their own activity – and that of Socrates – from the sophists. If one is so inclined, sophistry can thus be regarded, in a conceptual as well as historical sense, as the ‘other’ of philosophy.

Perhaps because of the interpretative difficulties mentioned above, the sophists have been many things to many people. For Hegel (1995/1840) the sophists were subjectivists whose sceptical reaction to the objective dogmatism of the presocratics was synthesised in the work of Plato and Aristotle. For the utilitarian English classicist George Grote (1904), the sophists were progressive thinkers who placed in question the prevailing morality of their time. More recent work by French theorists such as Jacques Derrida (1981) and Jean Francois-Lyotard (1985) suggests affinities between the sophists and postmodernism.

This article provides a broad overview of the sophists, and indicates some of the central philosophical issues raised by their work. Section 1 discusses the meaning of the term sophist. Section 2 surveys the individual contributions of the most famous sophists. Section 3 examines three themes that have often been taken as characteristic of sophistic thought: the distinction between nature and convention, relativism about knowledge and truth and the power of speech. Finally, section 4 analyses attempts by Plato and others to establish a clear demarcation between philosophy and sophistry.

Insect based navigation and its applications to the autonomous control of mobile robots

Giving robots the ability to autonomously move around in various real-world environments has been a major goal of AI (artificial intelligence) for quite some time. To this end it is vital for robots to be able to perceive their surroundings in 3D; they must be able to estimate the range of obstacles in their path.

Animals navigate through various uncontrolled environments with seemingly little effort. Flying insects, especially, are quite adept at manoeuvring in complex, unpredictable and possibly hostile and hazardous environments.

In this paper it is shown that very simple motion cues, inspired by the visual navigation of flying insects, can be used to provide a mobile robot with the ability to successfully traverse a corridor environment. Equipping an autonomous mobile robot with the ability to successfully navigate real-word environments (in real-time) constitutes a major challenge for AI and robotics. It is in this area that insect based navigation has something to offer.

Insect inspired behaviours for the autonomous control of mobile robots

Animals navigate through various uncontrolled environments with seemingly little effort. Flying insects, especially, are quite adept at manoeuvring in complex, unpredictable and possibly hostile environments. Through both simulation and real-world experiments, we demonstrate the feasibility of equipping a mobile robot with the ability to navigate a corridor environment, in real time, using principles based on insect-based visual guidance. In particular we have used the bees’ navigational strategy of measuring object range in terms of image velocity. We have also shown the viability and usefulness of various other insect behaviours: (i) keeping walls equidistant, (ii) slowing down when approaching an object, (iii) regulating speed according to tunnel width, and (iv) using visual motion as a measure of distance travelled.

Local energy, the pre-envelope, and filter resolution

We examine the construction of new filters for computing local energy, and compare these filters with the Gabor filters and the three-point-filter of Venkatesh [l]. Further, we demonstrate that the effect of convolution with complex Gabor filters is to band-pass (with some differentiating effect) and compute the local energy of the result. The magnitude of the resulting local energy is then used to detect features [2], [3] (step features, texture etc.), and the phase is used to classify the detected features [l], [4] or provide disparity information for stereo [5] and motion work [6], [7]. Each of these types of information can be obtained at multiple resolutions, enabling the use of course to fine strategies for computing disparity, and allowing the discrimination of image textures on the basis of which parts of the Fourier domain they dominate [8], [9].

Discovery of activity structures using the hierarchical hidden Markov model

In building a surveillance system for monitoring people behaviours, it is important to understand the typical patterns of people's movement in the environment. This task is difficult when dealing with high-level behaviours. The flat model such as the hidden Markov model (HMM) is inefficient in differentiating between signatures of such behaviours. This paper examines structure learning for high-level behaviours using the hierarchical hidden Markov model (HHMM).We propose a two-phase learning algorithm in which the parameters of the behaviours at low levels are estimated first and then the structures and parameters of the behaviours at high levels are learned from multi-camera training data. Our algorithm is then evaluated using data from a real environment, demonstrating the robustness of the learned structure in recognising people's behaviour.

Performance and anthropometric characteristics of prospective elite junior Australian footballers : a case study in one junior team

The aim of the study was to compare anthropometric and physical performance data of players who were selected for a Victorian elite junior U18 Australian rules football squad. Prior to the selection of the final training squad, 54 players were assessed using a battery of standard anthropometric and physical performance tests. Multivariate analysis (MANOVA) showed significant (p < 0.05) differences between selected and non-selected players when height, mass, 20-m sprint, agility and vertical jump height were considered collectively. Univariate analysis revealed that the vertical jump was the only significant (p < 0.05) individual test and a near significant trend (p = 0.07) for height differentiating between selected and non-selected players with medium effect sizes for all other tests except endurance. In this elite junior football squad, physical characteristics can be observed that discriminate between players selected and non-selected, and demonstrates the value of physical fitness testing within the talent identification process of junior (16–18 years) players for squad and/or team selection. Based on MANOVA results, the findings from this study suggest team selection appeared to be related to a generally higher performance across the range of tests. Further, age was not a confounding variable as players selected tended to be younger than those non-selected. These findings reflect the general consensus that, in state-based junior competition, there is evidence of promoting overall player development, selecting those who are generally able to fulfil a range of positions and selecting players on their potential.

Gaming maching addiction : the role of avoidance, accessibility and social support

Commonality in etiology and clinical expression plus high comorbidity between pathological gambling and substance use disorders suggest common underlying motives. It is important to understand common motivators and differentiating factors. An overarching framework of addiction was used to examine predictors of problem gambling in current electronic gaming machine (EGM) gamblers. Path analysis was used to examine the relationships between antecedent factors (stressors, coping habits, social support), gambling motivations (avoidance, accessibility, social) and gambling behavior. Three hundred and forty seven (229 females: M = 29.20 years, SD = 14.93; 118 males: M = 29.64 years, SD = 12.49) people participated. Consistent with stress, coping and addiction theory, situational life stressors and general avoidance coping were positively related to avoidance-motivated gambling. In turn, avoidance-motivated gambling was positively related to EGM gambling frequency and problems. Consistent with exposure theory, life stressors were positively related to accessibility-motivated gambling, and accessibility-motivated gambling was positively related to EGM gambling frequency and gambling problems. These findings are consistent with other addiction research and suggest avoidance-motivated gambling is part of a more generalized pattern of avoidance coping with relative accessibility to EGM gambling explaining its choice as a method of avoidance. Findings also showed social support acted as a direct protective factor in relation to gambling frequency and problems and indirectly via avoidance and accessibility gambling motivations. Finally, life stressors were positively related to socially motivated gambling but this motivation was not related to either social support or gambling behavior suggesting it has little direct influence on gambling problems.

Detecting and managing depressed patients : palliative care nurses' self-efficacy and perceived barriers to care

Background: Depression is a highly prevalent yet under-recognized and under-treated psychiatric illness in patients receiving palliative care. Nurses are the front-line health care professionals in these settings and are well-positioned to detect depressive symptoms and initiate pathways to care. Previous research suggests, however, that nurses' confidence and skills in relation to this task are low, and there appear to be a number of barriers within these settings that may impede nurses' engagement in this process.

Methods: To further investigate these factors, a quantitative study was carried out with 69 palliative care nurses from three palliative care services in Australia.

Results: A number of issues were identified, including the need for further training in the signs and symptoms of depression, issues around discussing depression with patients and their family members, and difficulty differentiating depressive symptoms from grief.

Conclusion: These findings provide insight into specific areas in which palliative care nurses would benefit from further training to improve detection rates for depression in this vulnerable population.

Muslim active citizenship in the West

Muslim Active Citizenship in the West investigates the emergence and nature of Muslims’ struggle for recognition as full members of society in Australia, Great Britain and Germany. What actions have been taken by Muslims to achieve equal civic standing? How do socio-political and socio-economic factors impact on these processes? And how do Muslims negotiate their place in a society that is often regarded as sceptical – if not hostile – towards Muslims’ desire to belong? This book sheds new light on Muslims’ path towards citizenship in Australia, Great Britain and Germany. Existing research and statistics on Muslims’ socio-economic status, community formation, claim-making and political responses, and the public portrayal of Islam are systematically examined. These insights are tested ‘through the eyes of Muslims’, based on in-depth interviews with Muslim community leaders and other experts in all three countries. The findings offer unique perspectives on Muslim resilience to be recognised as equal citizens of Islamic faith in very different socio-political national settings. Pursuing an interdisciplinary and comparative approach, this book examines the country-specific interplay of historical, institutional, political, and identity dimensions of Muslims’ active citizenship and will be invaluable for students and researchers with an interest in Sociology, Religious Studies and Political Science.

Versican processing by a disintegrin-like and metalloproteinase domain with thrombospondin-1 repeats proteinases-5 and -15 facilitates myoblast fusion

Skeletal muscle development and regeneration requires the fusion of myoblasts into multinucleated myotubes. Because the enzymatic proteolysis of a hyaluronan and versican-rich matrix by ADAMTS versicanases is required for developmental morphogenesis, we hypothesized that the clearance of versican may facilitate the fusion of myoblasts during myogenesis. Here, we used transgenic mice and an in vitro model of myoblast fusion, C2C12 cells, to determine a potential role for ADAMTS versicanases. Versican processing was observed during in vivo myogenesis at the time when myoblasts were fusing to form multinucleated myotubes. Relevant ADAMTS genes, chief among them Adamts5 and Adamts15, were expressed both in developing embryonic muscle and differentiating C2C12 cells. Reducing the levels of Adamts5 mRNA in vitro impaired myoblast fusion, which could be rescued with catalytically active but not the inactive forms of ADAMTS5 or ADAMTS15. The addition of inactive ADAMTS5, ADAMTS15, or full-length V1 versican effectively impaired myoblast fusion. Finally, the expansion of a hyaluronan and versican-rich matrix was observed upon reducing the levels of Adamts5 mRNA in myoblasts. These data indicate that these ADAMTS proteinases contribute to the formation of multinucleated myotubes such as is necessary for both skeletal muscle development and during regeneration, by remodeling a versican-rich pericellular matrix of myoblasts. Our study identifies a possible pathway to target for the improvement of myogenesis in a plethora of diseases including cancer cachexia, sarcopenia, and muscular dystrophy.

Baudrillard, postfeminism, and the image makeover

Jean Baudrillard’s claim that we inhabit a transaesthetic and integral reality raises significant questions for feminists seeking to analyze how women are represented in Western media through the neoliberal guises of empowerment and choice. These questions relate to the impossibility of differentiating between feminist and antifeminist themes amid the implosive forces of a virtualized significatory and political economy. To map what a feminist-Baudrillardian approach to postfeminist media images might look like, this essay engages with current feminist theorizing about the postfeminist condition via the example of the UK reality makeover program How to Look Good Naked. In my analysis of this series, Baudrillard’s radical approach to the world “as is” illuminates some of the challenges an economy of exclusive positivity raises for the task of critical feminist inquiry. 

The resurrection plant Sporobolus stapfianus: An unlikely model for engineering enhanced plant biomass?

The resurrection grass Sporobolus stapfianus Gandoger can rapidly recover from extended periods of time in the desiccated state (water potential equilibrated to 2% relative humidity) (Gaff and Ellis, Bothalia 11:305–308 1974; Gaff and Loveys, Transactions of the Malaysian Society of Plant Physiology 3:286–287 1993). Physiological studies have been conducted in S. stapfianus to investigate the responses utilised by these desiccation-tolerant plants to cope with severe water-deficit. In a number of instances, more recent gene expression analyses in S. stapfianus have shed light on the molecular and cellular mechanisms mediating these responses. S. stapfianus is a versatile research tool for investigating desiccation-tolerance in vegetative grass tissue, with several useful characteristics for differentiating desiccation-tolerance adaptive genes from the many dehydration-responsive genes present in plants. A number of genes orthologous to those isolated from dehydrating S. stapfianus have been successfully used to enhance drought and salt tolerance in model plants as well as important crop species. In addition to the ability to desiccate and rehydrate successfully, the survival of resurrection plants in regions experiencing short sporadic rainfall events may depend substantially on the ability to tightly down-regulate cell division and cell wall loosening activities with decreasing water availability and then grow rapidly after rainfall while water is plentiful. Hence, an analysis of gene transcripts present in the desiccated tissue of resurrection plants may reveal important growth-related genes. Recent findings support the proposition that, as well as being a versatile model for devising strategies for protecting plants from water-loss, resurrection plants may be a very useful tool for pinpointing genes to target for enhancing growth rate and biomass production.

Bloom filter based secure and anonymous DSR protocol in wireless ad hoc networks

Wireless ad hoc networks, especially in the hostile environment, are vulnerable to traffic analysis which allows the adversary to trace the routing messages and the sensitive data packets. Anonymity mechanism in ad hoc networks is a critical securing measure method employed to mitigate these problems. In this paper, we propose a novel secure and anonymous source routing protocol, called SADSR, based on Dynamic Source Routing (DSR) for wireless ad hoc networks. In the proposed scheme, we use the pseudonym, pseudonym based cryptography and the bloom filter to establish secure and anonymous routing in wireless ad hoc networks. Compared to other anonymous routing protocol, SADSR is not only anonymous but also the secure in the routing discover process and data transmission process.

Shifts in thinking and practice: reflecting on an applied learning programme

The implementation of the first iteration of a curriculum for an applied learning programme for police trainers received a hostile response from participants. It was perceived as irrelevant and supplanting, rather than augmenting, trainers’ fixed and untested training practices. This paper presents the reflections on my journey as a nonpolice person straddling an outsider-insider position while challenging that which is taken-for-granted and introducing an educative intent, as opposed to a doctrinal, technical intent, to police training. On a daily basis I simultaneously work within and against the prevailing D/discourses and dominant subcultures, while establishing and nurturing relationships with police trainers: being teacher, coach and ‘critical friend’. The response to the second and now third iterations of the learning programme has been increasingly positive, revealing shifts in trainers’ thinking and practice.
