New pleasures and old dangers: reinventing male sex work

Understandings of male sex workers (MSWs) shift with technological, conceptual, and social changes. Research has historically constructed MSWs as psychologically unstable, desperate, or destitute victims and their clients as socially deviant perverts. These perceptions, however, are no longer supported by contemporary research and changing societal perceptions of the sex industry, challenging how we understand and describe “escorts.” The changing understandings of sexuality and the increasing power of the Internet are both important forces behind recent changes in the structure and organization of MSWs. The growth in the visibility and reach of escorts has created opportunities to form an occupational account of MSWs that better accounts for the dynamic and diverse nature of the MSW experience in the early 21st century. Recent changes in the structure and organization of male sex work have provided visibility to the increasingly diverse geographical distribution of MSW, the commodification of race and racialized desire, new populations of heterosexual men and women as clients, and the successful dissemination of safer sexual messages to MSWs through online channels. This article provides a broad overview of the literature on MSWs, concentrating its focus on studies that have emerged over the past 20 years and identifying areas for future research.

Emotional expressions preferentially elicit implicit evaluations of faces also varying in race or age

Both facial cues of group membership (race, age, and sex) and emotional expressions can elicit implicit evaluations to guide subsequent social behavior. There is, however, little research addressing whether group membership cues or emotional expressions are more influential in the formation of implicit evaluations of faces when both cues are simultaneously present. The current study aimed to determine this. Emotional expressions but not race or age cues elicited implicit evaluations in a series of affective priming tasks with emotional Caucasian and African faces (Experiments 1 and 2) and young and old faces (Experiment 3). Spontaneous evaluations of group membership cues of race and age only occurred when those cues were task relevant, suggesting the preferential influence of emotional expressions in the formation of implicit evaluations of others when cues of race or age are not salient. Implications for implicit prejudice, face perception, and person construal are discussed.

Antioxidant responses to an acute ultra-endurance exercise: Impact on DNA stability and indications for an increased need for nutritive antioxidants in the early recovery phase

Antioxidant requirements have neither been defined for endurance nor been defined for ultra-endurance athletes. To verify whether an acute bout of ultra-endurance exercise modifies the need for nutritive antioxidants, we aimed (1) to investigate the changes of endogenous and exogenous antioxidants in response to an Ironman triathlon; (2) to particularise the relevance of antioxidant responses to the indices of oxidatively damaged blood lipids, blood cell compounds and lymphocyte DNA and (3) to examine whether potential time-points of increased susceptibility to oxidative damage are associated with alterations in the antioxidant status. Blood that was collected from forty-two well-trained male athletes 2 d pre-race, immediately post-race, and 1, 5 and 19 d later was sampled. The key findings of the present study are as follows: (1) Immediately post-race, vitamin C, alpha-tocopherol, and levels of the Trolox equivalent antioxidant capacity, the ferric reducing ability of plasma and the oxygen radical absorbance capacity (ORAC) assays increased significantly. Exercise-induced changes in the plasma antioxidant capacity were associated with changes in uric acid, bilirubin and vitamin C. (2) Significant inverse correlations between ORAC levels and indices of oxidatively damaged DNA immediately and 1 d post-race suggest a protective role of the acute antioxidant responses in DNA stability. (3) Significant decreases in carotenoids and gamma-tocopherol 1 d post-race indicate that the antioxidant intake during the first 24 h of recovery following an acute ultra-endurance exercise requires specific attention. Furthermore, the present study illustrates the importance of a diversified and well-balanced diet to maintain a physiological antioxidant status in ultra-endurance athletes in reference to recommendations.

No acute and persistent DNA damage after an Ironman triathlon

During acute and strenuous exercise, the enhanced formation of reactive oxygen species can induce damage to lipids, proteins, and nucleic acids. The aim of this study was to investigate the effect of an Ironman triathlon (3.8 km swim, 180 km cycle, 42 km run), as a prototype of ultra-endurance exercise, on DNA stability. As biomarkers of genomic instability, the number of micronuclei, nucleoplasmic bridges, and nuclear buds were measured within the cytokinesis-block micronucleus cytome assay in once-divided peripheral lymphocytes of 20 male triathletes. Blood samples were taken 2 days before, within 20 min after the race, and 5 and 19 days post-race. Overall, the number of micronuclei decreased (P < 0.05) after the race, remained at a low level until 5 days post-race, and declined further to 19 days post-race (P < 0.01). The frequency of nucleoplasmic bridges and nuclear buds did not change immediately after the triathlon. The number of nucleoplasmic bridge declined from 2 days pre-race to 19 days post-exercise (P < 0.05). The frequency of nuclear buds increased after the triathlon, peaking 5 days post-race (P < 0.01) and decreased to basic levels 19 days after the race (P < 0.01). The results suggest that an Ironman triathlon does not cause long-lasting DNA damage in well-trained athletes.

Well-trained, healthy triathletes experience no adverse health risks regarding oxidative stress and DNA damage by participating in an ultra-endurance event

Also physical exercise in general is accepted to be protective, acute and strenuous exercise has been shown to induce oxidative stress. Enhanced formation of free radicals leads to oxidation of macromolecules and to DNA damage. On the other hand ultra-endurance events which require strenuous exercise are very popular and the number of participants is continuously increasing worldwide. Since only few data exists on Ironman triathletes, who are prototypes of ultra-endurance athletes, this study was aimed at assessing the risk of oxidative stress and DNA damage after finishing a triathlon and to predict a possible health risk. Blood samples of 42 male athletes were taken 2 days before, within 20 min after the race, 1, 5 and 19 days post-race. Oxidative stress marker increased only moderately after the race and returned to baseline after 5 days. Marker of DNA damage measured by the SCGE assay with and without restriction enzymes as well as by the sister chromatid exchange assay did either show no change or deceased within the first day after the race. Due to intake during the race and the release by the cells plasma concentrations of vitamin C and α-tocopherol increased after the event and returned to baseline 1 day after. This study indicates that despite a temporary increase in some oxidative stress markers, there is no persistent oxidative stress and no DNA damage in response to an Ironman triathlon in trained athletes, mainly due to an appropriate antioxidant intake and general protective alterations in the antioxidant defence system.

Beyond social justice agendas: Indigenous knowledges in pre-service teacher education and practice in Australia

The space and positioning of Indigenous knowledges (IK) within Australian curricula and pedagogy are often contentious, informed by the broader Australian socio-cultural, political and economic landscape. Against changing educational policy, historically based on the myth of terra nullius, we discuss the shifting priorities for embedding Indigenous knowledges in educational practice in university and school curricula and pedagogy. In this chapter, we argue that personal and professional commitment to social justice is an important starting point for embedding Indigenous knowledges in the Australian school curricula and pedagogy. Developing teacher knowledge around embedding IK is required to enable teachers’ preparedness to navigate a contested historical/colonising space in curriculum decision-making, teaching and learning. We draw one mpirical data from a recent research project on supporting pre-service teachers as future curriculum leaders; the project was funded by the Office of Learning and Teaching (OLT). This project aimed to support future curriculum leaders to develop their knowledge of embedding IK at one Australian university. We propose supporting the embedding of IK in situ with pre-service teachers and their supervising teachers on practicum in real, sustained and affirming ways that shifts the recognition of IK from personal commitment to social justice in education, to one that values Indigenous knowledges as content to educate (Connell, 1993). We argue that sustained engagement with and appreciation of IKhas the potential to decolonise Australian curricula, shift policy directions and enhance race relations between Indigenous and non-Indigenous Australians .

Critically deconstructing race through a multimodal analysis of iPad Tellagami videos

Drawing on multimodal texts produced by an Indigenous school community in Australia, I apply critical race theory and multimodal analysis (Jewitt, 2011) to decolonise digital heritage practices for Indigenous students. This study focuses on the particular ways in which students’ counter-narratives about race were embedded in multimodal and digital design in the development of a digital cultural heritage (Giaccardi, 2012). Data analysis involved applying multimodal analysis to the students’ Gamis, following social semiotic categories and principles theorised by Kress and Bezemer (2008), and Jewitt (2006, 2011). This includes attending to the following semiotic elements: visual design, movement and gesture, gaze, and recorded speech, and their interrelationships. The analysis also draws on critical race theory to interpret the students’ representations of race. In particular, the multimodal texts were analysed as a site for students’ views of Indigenous oppression in relation to the colonial powers and ownership of the land in Australian history (Ladson-Billings, 2009). Pedagogies that explore counter-narratives of cultural heritage in the official curriculum can encourage students to reframe their own racial identity, while challenging dominant white, historical narratives of colonial conquest, race, and power (Gutierrez, 2008). The children’s multimodal “Gami” videos, created with the iPad application, Tellagami, enabled the students to imagine hybrid, digital social identities and perspectives of Australian history that were tied to their Indigenous cultural heritage (Kamberelis, 2001).

Playing "Nordic": The Women of Niskavuori, Agri/Culture, and Imagining Finland on the Third Reich Stage

The theatrical censorship of the Third Reich considered the playwright's race and politics alongside the content of the drama. Given the political stigma of its "leftist" author, it is rather surprising that Hella Wuolijoki's Niskavuoren naiset opened in 1938 at the Staatliches Schauspielhaus in Hamburg. The play ran for fourteen performances before being closed by the Reichsdramaturgie, apparently at the instigation of Finnish critics. Yet this was not the end of the play's or its author's fortunes in the Third Reich, as the possibility of staging the play was raised several times over the next four years, coming to a close in 1942. Playing "Nordic" examines the ideological and theatrical background of this extended "cultural performance," as a means to reopening and reconstructing the work of the 1938 Die Frauen auf Niskavuori. Written by a Finnish, northern, "Nordic" author, and preoccupied with the dynamics of rural culture in an increasingly urbanized world, Niskavuoren naiset was understood in the Third Reich to illustrate and reinforce the racial, agri/cultural themes of Blut und Boden ("veri ja maa"). Playing "Nordic" examines this thematic relationship in three phases. The first phase uses archival materials to investigate the Reichsdramaturgie's understanding of the play and its author, and its ongoing discussion of Wuolijoki from 1937 to 1942. Play evaluator Sigmund Graff's description of Niskavuoren naiset as hamsunartig, or "Hamsun-esque," inspires the second phase of the dissertation, which first elaborates the meanings of Blut und Boden through a reading of contemporary "racial" theory and anthropology, and then assesses the representation of Finland within this discourse, one of the dominant cultural paradigms of the Third Reich. Imaging Finland for German audiences, the play stood among analogous, continued efforts to represent Finland and the rural life in the Third Reich, colored by Blut und Boden: art and agricultural exhibitions, essays and propaganda literature, mass demonstrations of the peasantry. This wider framework for the performance of "Finland" materializes the abstract or theoretical program of Blut und Boden in its everyday performed meanings; as such it provides the essential background for reading the Hamburg production of Die Frauen auf Niskavuori, which sustains the third and final phase. The German translation and the Hamburg photographic record are compared with the Helsinki premiere to assess the impact of Blut und Boden on the representation of Wuolijoki's play in the Third Reich. The journalistic critical response illuminates the effect that the dramatic complex of rural and racial values - generically identified as Bauerndrama in the Third Reich - had on the reception of the play; at the same time, both visual and critical documents also suggest possible moments of theatrical dissent in the Hamburg production. Playing "Nordic" undertakes a documentary and cultural reading of the changing theatrical meanings of Wuolijoki's Niskavuoren naiset as it crossed the frontier from Finland to the stage of the Third Reich. It also provides a model for the ways theatrical signification operates within a network of cultural and ideological meanings, suggesting the ideological work of theatrical production depends on, reinforces, and contests that tissue of values. Although Finnish criticism of Niskavuoren naiset has assumed the play's Blut und Boden resonance contributed to Wuolijoki's success in the Third Reich, this study shows a considerably more complex situation. This revealing production dramatizes the changing uses of plays in a politicized national and transnational context. As part of the framing of "Nordic" identity on the wider stage of the Third Reich, Die Frauen auf Niskavuori exemplifies the conjunction of concurrent - sometimes independent, sometimes interlocking - "racial" and national ideologies.

Community, Power, and Colonialism: The U.S. Army in Southern Arizona and New Mexico, 1866-1886

Empire is central to U.S. history. When we see the U.S. projecting its influence on a global scale in today s world it is important to understand that U.S. empire has a long history. This dissertation offers a case study of colonialism and U.S. empire by discussing the social worlds, labor regimes, and culture of the U.S. Army during the conquest of southern Arizona and New Mexico (1866-1886). It highlights some of the defining principles, mentalities, and characteristics of U.S. imperialism and shows how U.S. forces have in years past constructed their power and represented themselves, their missions, and the places and peoples that faced U.S. imperialism/colonialism. Using insights from postcolonial studies and whiteness studies, this work balances its attention between discursive representations (army stories) and social experience (army actions), pays attention to silences in the process of historical production, and focuses on collective group mentalities and identities. In the end the army experience reveals an empire in denial constructed on the rule of difference and marked by frustration. White officers, their wives, and the white enlisted men not only wanted the monopoly of violence for the U.S. regime but also colonial (mental/cultural) authority and power, and constructed their identity, authority, and power in discourse and in the social contexts of the everyday through difference. Engaged in warfare against the Apaches, they did not recognize their actions as harmful or acknowledge the U.S. invasion as the bloody colonial conquest it was. White army personnel painted themselves and the army as liberators, represented colonial peoples as racial inferiors, approached colonial terrain in terms of struggle, and claimed that the region was a terrible periphery with little value before the arrival of white civilization. Officers and wives also wanted to place themselves at the top of colonial hierarchies as the refined and respectable class who led the regeneration of the colony by example: they tried to turn army villages into islands of civilization and made journeys, leisure, and domestic life to showcase their class sensibilities and level of sophistication. Often, however, their efforts failed, resulting in frustration and bitterness. Many blamed the colony and its peoples for their failures. The army itself was divided by race and class. All soldiers were treated as laborers unfit for self-government. White enlisted men, frustrated by their failures in colonial warfare and by constant manual labor, constructed worlds of resistance, whereas indigenous soldiers sought to negotiate the effects of colonialism by working in the army. As colonized labor their position was defined by tension between integration and exclusion and between freedom and colonial control.

Acceptance of prostitution and its social determinants in Canada

The nature of collective perception of prostitution is understudied in Canada. Except some rudimentary reports on the percentages of the key legal options, multivariate analysis has never been used to analyze the details of public opinion on prostitution. The current study explores the trend of public attitude toward prostitution acceptability in Canada over a 25-year span and examines the social determinants of the acceptability of prostitution, using structural equation modeling (SEM), which allows researchers to elaborate both direct and indirect effects (through mediating variables) on the outcome variable. Results show that the public has become more acceptant of prostitution over time. In addition, the less religious, less authoritarian, and more educated are more acceptant of prostitution than the more religious, more authoritarian, and less well educated. The effects of religiosity and authoritarianism mediate out the direct effects of age, gender, gender equality, marriage, marriage as an outdated institution, Quebec, race, and tolerance. The findings may serve as a reference point for the law reform regarding the regulation of prostitution in Canada.

Social determinants of health and diabetic foot disease

Background Diabetic foot disease (DFD) is the leading cause of hospitalisation and lower extremity amputation (LEA) in people with diabetes. Many studies have established the relationship between DFD and clinical risk factors, such as peripheral neuropathy and peripheral arterial disease. Other studies have identified the relationship between diabetes and non-clinical risk factors termed social determinants of health (SDoH), such as socioeconomic status. However, it appears very few studies have investigated the relationship between DFD and SDoH. This paper aims to review the existing literature investigating the relationship between DFD and the SDoH factors socioeconomic status (SES), race and geographical remoteness (remoteness). Process Electronic databases (MEDLINE, CINAHL, and PubMed) were searched for studies reporting SES, race (including Aboriginal and Torres Strait Islander in Australia) and remoteness and their relationship to DFD and LEA. Exclusion criteria were studies conducted in developing countries and studies published prior to 2000. Findings Forty-eight studies met the inclusion criteria and were reviewed; 10 in Australia. Overall, 28 (58%) studies investigated LEA, 10 (21%) DFD, and 10 (21%) DFD and LEA as the DFD-related outcome. Thirty-six (75%) studies investigated the SDoH risk factor of race, 22 (46%) SES, and 20 (42%) remoteness. SES, race and remoteness were found to be individually associated with LEA and DFD in the majority of studies. Only four studies investigated interactions between SES, race and remoteness and DFD with contrasting findings. All four studies used only LEA as their investigated outcome. No Australian studies investigate the interaction of all three SDoH risk factors on DFD outcomes. Conclusions The SDoH risk factors of SES, race and GR appear to be individually associated with DFD. However, only few studies investigated the interaction of these three major SDoH risk factors and DFD outcomes with contrasting results. There is a clear gap in this area of DFD research and particularly in Australia. Until urgent future research is performed, current practice and policy does not adequately take into consideration the implication of SDoH on DFD.

Movimentos negros, Estado e participação institucional no Brasil e Colômbia em perspectiva comparada

A presente tese examina a relação entre movimentos negros e estado no Brasil e na Colômbia no período imediatamente anterior à promulgação de suas respectivas cartas constitucionais e ao longo das duas décadas que se seguem à adoção dessas novas legislações. No final dos anos 1980, os discursos oficiais que celebravam a mestiçagem e a democracia racial vão sendo gradativamente vertidos para complexas noções de cidadania multicultural, direitos étnico-territoriais e igualdade racial. Assim, este estudo analisa o papel desempenhado pelos movimentos negros para a mudança nas legislações estatais e suas consequências em termos de incremento na participação institucional e reorientação dos repertórios de ação coletiva dos movimentos. Os resultados encontrados por este trabalho, analisados à luz das teorias do Processo Político, indicam que quanto maior a abertura de oportunidades políticas e discursivas maior o impacto políticoinstitucional do movimento negro. A primeira parte da tese demonstra que mudanças no cenário político internacional, com a ascensão de discursos sobre multiculturalismo, e nos contextos nacionais, com o aumento da instabilidade política e processos de redemocratização política, propiciaram uma importante abertura de oportunidades políticas paras os movimentos negros em ambos os países. A tese argumenta ainda que os debates acadêmicos sobre raça e etnicidade também influenciaram os discursos e estratégias dos movimentos negros em seus respectivos países. De maneira específica, no Brasil, o discurso sobre igualdade racial, forjado nas fronteiras entre academia e ativismo, adquire centralidade política tanto para atores estatais quanto para atores não-estatais. Na Colômbia, em contrapartida, é o discurso étnico-territorial que orienta os debates por inclusão sociopolítica de afrocolombianos. A segunda parte da tese analisa a participação institucional dos movimentos negros em ambos os países. São examinados, especificamente, a criação de legislações, políticas públicas e canais formais de participação para as populações afrodescendentes e seu impacto nas estratégias, estrutura organizacional e redes de solidariedade dos movimentos negros. Investiga-se também a ampliação dos vínculos entre os movimentos e órgãos governamentais, a consolidação dos laços com partidos políticos e as interações cooperativas e/ou conflitivas com o estado. A tese contribui para o campo de estudos afrolatinos, ao descortinar processos emergentes de politização racial na América do Sul, e para a ampliação do debate acerca das relações entre os movimentos sociais e institucionalidade, aludindo à novas possibilidades interpretativas que escapem ao já defasado binômio autonomia versus cooptação que têm marcado a literatura sobre a temática.
