Signposts that helped a white activist find her way as a critical ally

As a white researcher setting out on a research journeywith Indigenous people, how could I deal with theparadox of being part of the problem I was seeking toaddress? Awareness of, and desire to minimise, theimpact of my white privilege would not automaticallycancel it out. Activist researchers who have challengedpowerful systems have a history of being condemned andostracised by colonial centres of power. Would it be myfate to be condemned by the colonial centre of power inwhich I found myself; the academy? Would I also becondemned by those not in positions of power? Whatsignposts could show me how to act, what to do and howto undertake the research journey?This paper outlines the intersecting theories I meldedtogether to use as a map for a critical activist allystandpoint when conducting research in IndigenousPrisoner Education in Western Australia. Drawing ontheories of whiteness, power, critical pedagogy, activismand standpoint theory, I attempt to navigate a directionthat allows for the struggle, uncertainties and paradoxesthat are what it means to work critically as an alliedactivist. I explore some of the challenges I face as acritical, activist ally who is exploring Indigenouseducation in Western Australian prisons. I invite audiencediscussion, feedback and reflection on these challenges

Gender and public relations: critical perspectives on voice, image and identity

Although there is a small body of feminist scholarship that problematizes gender in public relations, gender is a relatively undefined area of thinking in the field and there have been few serious studies of the socially constructed roles defining women and men in public relations. This book is positioned within the critical public relations stream. Through the prism of 'gender and public relations', it examines not only the manipulatory, but also the emancipatory, subversive and transformatory potential of public relations for the construction of meaning. Its focus is on the dynamic interrelationships arising from public relations activities in society and the gendered, lived experiences of people working in the occupation of public relations. There are many previously unexplored areas within and through public relations which the book examines. These include: • the production of social meaning and power relations. • advocacy and activist campaigns for social and political change. • the negotiation of identity, diversity and cultural practice. • celebrity, bodies, fashion and harassment in the workplace. • notions of managing reputation and communicating policy. In extending the field of inquiry, this edited collection highlights how gender is accomplished and transformed, and, thus how power is exercised and inequality (re)produced or challenged in public relations. The book will expand thinking about power relations and privilege for both women and men and how these are affected by the interplay of social, cultural and institutional practices.

A sword with two edges: propagation studies on both positive and negative information in online social networks

Online social networks (OSN) have become one of the major platforms for people to exchange information. Both positive information (e.g., ideas, news and opinions) and negative information (e.g., rumors and gossips) spreading in social media can greatly influence our lives. Previously, researchers have proposed models to understand their propagation dynamics. However, those were merely simulations in nature and only focused on the spread of one type of information. Due to the human-related factors involved, simultaneous spread of negative and positive information cannot be thought of the superposition of two independent propagations. In order to fix these deficiencies, we propose an analytical model which is built stochastically from a node level up. It can present the temporal dynamics of spread such as the time people check newly arrived messages or forward them. Moreover, it is capable of capturing people's behavioral differences in preferring what to believe or disbelieve. We studied the social parameters impact on propagation using this model. We found that some factors such as people's preference and the injection time of the opposing information are critical to the propagation but some others such as the hearsay forwarding intention have little impact on it. The extensive simulations conducted on the real topologies confirm the high accuracy of our model.

Rethinking creativity: three case studies of the social processes of creativity

Creativity and innovation are often seen as being important in terms of organisations, not only dealing with large amounts of change, but also being able to flourish in uncertain times. Yet, despite large amounts of creativity research, it continues to be a contested subject and fragmented field which leaves researchers without clear direction. Thus the approach to studying creativity needs to be rethought in order to develop new insights into the phenomenon. This research contributes to the debate on creativity by developing concepts around how creativity unfolds within a specific social context. It does this by approaching the study of creativity from a critical perspective and conducting a series of case studies into creativity in organisations. This research finds that, while the production of an artefact is a prerequisite, creativity is not an enduring feature of a given artefact. Rather, creativity exists when an artefact is labelled creative within a particular social system. In addition, as part of the interpretive research process, aspects of identity work emerged. Exploration of creativity as part of the process of identity work provides novel insight into creativity and a conceptual map which may be utilized as part of ongoing research into creativity. This research makes a significant contribution to the understanding of creativity by unpacking the processes of creativity, in three diverse organisational settings, and showing how creativity may be conceptualised as a contextually bound, socially constructed label which is underpinned by identity related motives.

A case study on critical reflection: a Chinese postgraduate in Australia

Critical reflection (CR) is at the core of postgraduate studies in c, and students from Asia in general, and from c in particular, often find the concept challenging when reading texts or applying it to written texts in English. This study reports on a case study of a Chinese postgraduate student in Australia. It explores the challenges and obstacles in terms of CR that she faced while completing her subjects in a TESOL program in Australia. These challenges were articulated in a semi-structured interview conducted with the student. Challenges include English language proficiency, lack of focus on writing in China where there is a lot of emphasis on memorisation, different systems of conceptualisation of topics in Chinese and English, and limited freedom of expression which is expressed as ‘authoritative’ control in the Chinese educational context.

In search of academic identity : physical education, sport science and the field of human movement studies

This thesis addresses the problem of the academic identity of the area traditionally referred to as physical education. The study is a critical examination of the argu ments for the justi cation of this area as an autonomous branch of knowledge. The investigation concentrates on a selected number of arguments. The data collection comprised articles books and proceedings of conferences. The preliminary assessment of these materials resulted in a classi cation of the arguments into three groups. The rst group comprises the arguments in favour of physical education as an academic discipline. The second includes the arguments supporting a science of sport. The third consists of the arguments in favour of to a eld of human movement study. The examination of these arguments produced the following results. (a) The area of physical education does not satisfy the conditions presupposed by the de nition of academic discipline. This is so because the area does not form an integrated system of scienti c theories. (b) The same di culty emerges from the examination of the ar guments for sport science. There is no science of sport because there is no integrated system of scienti c theories related to sport. (c) The arguments in favour of a eld of study yielded more productive results. However di culties arise from the de nition of human movement. The analysis of this concept showed that its limits are not well demarcated. This makes it problematic to take human movement as the focus of a eld of studies. These aspects led to the conclusion that such things as an academic discipline of physical education sport science and eld of human movement studies do not exist. At least there are not such things in the sense of autonomous branches of knowledge. This does not imply that a more integrated inquiry based on several disciplines is not possible and desirable. This would enable someone entering phys ical education to nd a more organised structure of knowledge with some generally accepted problem situations procedures and theories on which to base professional practice.

Competition and cooperation between international courts: a critical approach to the new paradigms of cross-border dispute resolution model

This article examines the arising cross-border dispute resolution models (Cooperation and Competition among national Courts) from a critical perspective. Although they have been conceived to surpass the ordinary solution of a Modern paradigm (exclusive jurisdiction, choice of court, lis pendens, forum non conveniens, among others), they are insufficient to deal with problems raised with present globalization, as they do not abandon aspects of that paradigm, namely, (i) statebased Law; and (ii) standardization of cultural issues.

Important, unimportant a critical anticipation of the assumptions of legal positivism in Alice in Wonderland

Almost a full century separates Lewis’ Alice in Wonderland (1865) and the second, lengthier and more elaborate edition of Hans Kelsen’s Pure Theory of Law (1960; first edition published in 1934). And yet, it is possible to argue that the former anticipates and critically addresses many of the philosophical assumptions that underlie and are elemental to the argument of the latter. Both texts, with the illuminating differences that arise from their disparate genre, have as one of their key themes norms and their functioning. Wonderland, as Alice soon finds out, is a world beset by rules of all kinds: from the etiquette rituals of the mad tea-party to the changing setting for the cricket game to the procedural insanity of the trial with which the novel ends. Pure Theory of Law, as Kelsen emphatically stresses, has the grundnorm as the cornerstone upon which the whole theoretical edifice rests2. This paper discusses some of the assumptions underlying Kelsen’s argument as an instance of the modern worldview which Lewis satirically scrutinizes. The first section (Sleepy and stupid) discusses Lewis critique of the idea that, to correctly apprehend an object (in the case of Kelsen’s study, law), one has to free it from its alien elements. The second section (Do bats eat cats?) discusses the notion of systemic coherence and its impact on modern ways of thinking about truth, law and society. The third section (Off with their heads!) explores the connections between readings of systems as neutral entities and the perpetuation of political power. The fourth and final section (Important, Unimportant) explains the sense in which a “critical anticipation” is both possible and useful to discuss the philosophical assumptions structuring some positivist arguments. It also discusses the reasons for choosing to focus on Kelsen’s work, rather than on that of Lewis’ contemporary, John Austin, whose The Province of Jurisprudence Determined (published in 1832) remains influential in legal debates today.

Meta-theories in research: positivism, postmodernism, and critical realism

No scholar or researcher is able to provide robust evidence that counters the scant reflection on metatheory – mostly ontology and epistemology – underlying management studies in general, and industrial marketing and purchasing research in particular. This paper is a contribution to the indispensable discussion of metatheoretical alternatives in research, and most importantly, the strengths and shortcomings thereof, and respective implications on research questions, objectives, and findings.

Immunohistochemistry in diagnostic veterinary pathology: a critical review

A técnica de imuno-histoquímica é usada na rotina diagnóstica e na pesquisa em patologia humana desde 1970, porém seu uso na patologia veterinária é relativamente recente, principalmente com objetivo diagnóstico. A maior dificuldade no uso da imuno-histoquímica na patologia veterinária tem sido a falta de anticorpos específicos para os tecidos animais. Na falta de anticorpos específicos para as espécies domésticas, a patologia veterinária freqüentemente faz uso de anticorpos que apresentam reatividade cruzada entre antígenos humanos e animais. O objetivo deste trabalho foi testar a reatividade cruzada de diversos anticorpos feitos para uso humano em tecido parafinado de algumas espécies animais, utilizando-se dos novos métodos de recuperação antigênica e amplificação da reação imuno-histoquímica. No presente estudo foi possível confirmar a aplicabilidade de que muitos anticorpos produzidos para diagnóstico imuno-histoquímico em patologia humana podem ser utilizados em patologia veterinária. Novos estudos são necessários a fim de se ampliar a lista de aplicabilidade desses anticorpos em diferentes espécies animais, levando sempre em consideração as variações de clones, diluições, métodos de recuperação antigênica e de revelação.

A critical analysis of isolation of Paracoccidioides brasiliensis from soil

The present review is a critical analysis of positive and negative reports of the isolation of Paracoccidioides brasiliensis from soil. The strains isolated from soil or soil-contaminated material (dogfood, penguin feces) by Batista et al. in Recife, Brazil, Negroni in the Argentinian Chaco, Albornoz in rural Venezuela, Silva-Vergara et al, in Ibia, Brazil, Ferreira et al, in Uberlandia, Brazil, and Gezuele et al. at the Uruguayan base in the Antarctic region, presented mycological characteristics consistent with P. brasiliensis. In most of these studies, morphological characterization was complemented with an evaluation of virulence and antigenicity, and biochemical or molecular analysis. These isolations, therefore, can be considered true, supporting the concept of soil as an important element in the ecology of the pathogen. The large number of negative reports in attempts involving soil samples and the low repeatability of isolation of the fungus from the same area indicate that the specific conditions supporting growth of the pathogen in soil have not been fully clarified.

Biomechanics Studies in Dentistry: Bioengineering Applied in Oral Implantology

The application of engineering knowledge in dentistry has helped the understanding of biomechanics aspects related to osseointegrated implants. Several techniques have been used to evaluate the biomechanical load oil implants comprising the use of photoelastic stress analysis, finite element stress analysis, and strain-gauge analysis. Therefore, the purpose of this Study was to describe engineering methods used in dentistry to evaluate the biomechanical behavior of osseointegrated implants. Photoelasticity provides good qualitative information oil the overall location and concentration of stresses but produces limited quantitative information. The method serves as ail important tool for determining the critical stress points in a material and is often used for determining stress concentration factors in irregular geometries. The application of strain-gauge method oil dental implants is based oil the use of electrical resistance strain gauges and its associated equipment and provides both in vitro and vivo measurements strains under static and dynamic loads. However, strain-gauge method provides only the data regarding strain at the gauge. Finite element analysis can Simulate stress using a computer-created model to calculate stress, strain, and displacement. Such analysis has the advantage of allowing several conditions to be changed easily and allows measurement of stress distribution around implants at optional points that are difficult to examine clinically All the 3 methodologies call be useful to evaluate biomechanical implant behavior close to the clinical condition but the researcher should have enough knowledge in model fabrication (experimental delineation) and results analysis.

Oral bisphosphonate-related osteonecrosis of the jaws in rheumatoid arthritis patients: a critical discussion and two case reports

Background: Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a clinical condition characterized by the presence of exposed bone in the maxillofacial region. Its pathogenesis is still undetermined, but may be associated with risk factors such as rheumatoid arthritis (RA). The aim of this paper is to report two unpublished cases of BRONJ in patients with RA and to conduct a literature review of similar clinical cases with a view to describe the main issues concerning these patients, including demographic characteristics and therapeutic approaches applied.Methods: Two case reports of BRONJ involving RA patients were discussedResults: Both patients were aging female taking alendronate for more than 3 years. Lesions were detected in stage II in posterior mandible with no clear trigger agent. The treatment applied consisted of antibiotics, oral rinses with chlorhexidine, drug discontinuation and surgical procedures. Complete healing of the lesions was achieved.Conclusions: This paper brings to light the necessity for rheumatologists to be aware of the potential risk to their patients of developing BRONJ and to work together with dentists for the prevention and early detection of the lesions. Although some features seem to link RA with oral BRONJ and act as synergistic effects, more studies should be developed to support the scientific bases for this hypothesis.
