The coupling between pulsation and mass loss in massive stars

To what extent can pulsational instabilities resolve the mass-loss problem of massive stars? How important is pulsation in structuring and modulating the winds of these stars? What role does pulsation play in redistributing angular momentum in massive stars? Although I cannot offer answers to these questions, I hope at the very least to explain how they come to be asked.Comment: 12 pages, 1 figure, to appear in proceedings of "Unsolved Problems in Stellar Physics" conference (Cambridge, UK, July 2007

Communicative Competence and Local Theories of Argumentation: The Case of Academic Citational Practices

When people argue in a specific context, they usually know exactly how to do that. The social knowledge participants have to form their expectations regarding the interaction is what we consider as their theory of argumentation. Elucidating the theories of the participants in argumentative exchanges is to formulate a local theory of argumentation. In this regard, we consider the ethnography of communication (EoC) as a framework to supplement our studies on argumentation. We believe there are three forms of social knowledge that affect how argumentation is conducted in context. First, participants know what is persuasive within their interactional context. Second, they know how this interaction is appropriately conducted. Third, they attempt to enact and recreate their understanding of the context through their talk. We use this framework to study citational practices in research. Each field has its own canonical authors. By citing them, academic practice reproduces the topics and audiences which have been deemed relevant. This is largely based on the norm that academic labor deserves acknowledgement. However, social structures may lead to exclusions of ideas and people, which are subsequently ignored. This is one of the issues raised after #MeToo. We consider whether in EoC acknowledgement should be given to other authors next to our canonical figure. We conclude that related research traditions like language socialization (Woolard & Schieffelin, 1994) and ideology (Schieffelin & Ochs, 1986) should also be considered within, and reinscribed into, EoC

The role of line managers in creating and maintaining healthy work environments on project construction sites

The focus of this article is healthy work environments in project-based construction work, and particularly a sub-element of the work environment, the food environment. Although it is well accepted that stressful work environments negatively impact on organisational and individual health indices and project construction produces some of the most severe work environments in the modern industrial landscape, the role of line managers in creating these environments is largely unknown. Healthy work environments are explored in this article because they contribute to the development of many ‘behavioral’ diseases such as Type 2 diabetes and cardiovascular disease, both of which are known problems amongst construction workers. Qualitative data were collected from eighty project-based construction workers and mangers on six large civil engineering construction projects in Brisbane, Australia. Unanimous views were expressed by all interviewees that managers should not and do not influence food choices on-site. However, results also revealed clear examples of managers making decisions about food environments, work and time pressures and permitted and discouraged behaviours on-site that impact on food choices. These findings indicate limited awareness of healthy work environments in construction with the impact of management actions being largely unrecognised and unintended. It suggests with more informed management decision-making, eating habits in construction are likely to improve

Cold Fire: Gender, Development, and the Film Industry in Cold War Thailand

Cold Fire is a study of how the international film industry in Thailand became a productive site for expressions of gendered cultural nationalism from the 1950s to the 1970s. National development projects expanded both state power and commercial markets for foreign and domestic film distribution. Those changes were facilitated by the domestic rise of military authoritarianism, intensive US political and economic intervention, rapid industrialization, and the communist threat in Asia. The United States and Thai governments used film as an instrument of psychological warfare to propagate conservative representations of Thai culture and society aimed at combating Communist sympathy. In doing so, they produced gendered representations of political behavior. Political consciousness was a masculine threat to the state. Thai women were positioned as inherently non-political, and therefore impervious to the threats of communism. The core values of Thai society promoted during this period, namely loyalty, passivity, and peacefulness, were implicitly feminine. Meanwhile, a new generation of filmmakers drew on the international discourse of modernization theory to promote technological advancement in Thai national cinema. The movement also articulated popular concerns, particularly towards the expanding presence of the United States and commercial development of the countryside. With the importation of commercial popular culture promoting alternative models for women and the visibility of prostitution alongside military bases, elite expressions of Thai femininity were used to delineate national difference in opposition to the United States. As such, Thai women were viewed as deeply vulnerable to the threat of Americanization. Indeed, government censors and filmmakers alike increasingly focused on representations of gender and sexuality in commercial films. With the 1970s, a small group of filmmakers brought to prominence a conservative national cinema that drew on elite notions of a romanticized agrarianism and traditional femininity to assert an image of Thai authenticity. I therefore argue that during the Cold War communism and Americanization functioned as mutually constitutive threats within a gendered Thai political and social discourse. Cinematic regulation and representation of Thai women as wives, mothers, lovers, and prostitutes produced the gendered boundaries of the modern state. National cultural identity was predicated on women’s unique and unequal status

Using a qualitative approach to research to build trust between a non-Aboriginal researcher and Aboriginal participants (Australia)

This article focuses on the qualitative methodologies employed in a research project developed in collaboration with Aboriginal advisors and gaining an in-depth understanding of Aboriginal Victorian peoples\u27 connection to their ancestral lands. It outlines why qualitative methodologies were used and highlights the ethical dimensions of working with Aboriginal Victorian communities. A research partnership was developed between Aboriginal Victorian communities and the non-Aboriginal researcher and this process was emphasised because in the past Australian Indigenous people have been grossly exploited in health research. The methods of semi-structured interviews and focus groups were used to gain a better understanding of this topic. The novel point of this article is that it provides an honest reflection of the benefits and limitations of this qualitative research process from the perspectives of a non-Aboriginal researcher and an Aboriginal participant, when emphasis is placed on a collaborative approach. The paper outlines what a successful qualitative research project looks like in Victorian Aboriginal communities. This can be used as a blueprint not only for working with Victorian Aboriginal communities, who have been marginalised within Australian society, but may also be relevant to other culturally diverse communities throughout the world

Geographic and ecologic distributions of the Anopheles gambiae complex predicted using a genetic algorithm

This is the publisher's version, also available electronically from http://www.ajtmh.org/content/70/2/105.The distribution of the Anopheles gambiae complex of malaria vectors in Africa is uncertain due to under-sampling of vast regions. We use ecologic niche modeling to predict the potential distribution of three members of the complex (A. gambiae, A. arabiensis, and A. quadriannulatus) and demonstrate the statistical significance of the models. Predictions correspond well to previous estimates, but provide detail regarding spatial discontinuities in the distribution of A. gambiae s.s. that are consistent with population genetic studies. Our predictions also identify large areas of Africa where the presence of A. arabiensis is predicted, but few specimens have been obtained, suggesting under-sampling of the species. Finally, we project models developed from African distribution data for the late 1900s into the past and to South America to determine retrospectively whether the deadly 1929 introduction of A. gambiae sensu lato into Brazil was more likely that of A. gambiae sensu stricto or A. arabiensis

'Dysgenic fertility' is an ideological, not a scientific, concept. A Comment on: 'Stability and change in male fertility patterns by cognitive ability across 32 birth cohorts' (2023), by Bratsberg & Rogeberg

Recently Bratsberg & Rogeberg (2023) presented an analysis in Biology Letters of how cognitive ability is associated with fertility in Norwegian men. Our concern relates to the theoretical framework of this paper. The analysis is framed around the concept of 'dysgenic fertility', which is treated throughout as a scientific theory, but 'dysgenic fertility' is not science, it is an ideological concept

Students Staging Resistance: Pedagogy/Performance/Praxis

This essay archives and reimagines a collaborative student performance—inJUSTICE—developed as part of a performance and social change course. Working within the framework of critical pedagogy, the intents of this piece are several: to offer strategies for teaching a course on performing resistance and mentoring students in the development of original work; to provide insight into how students, primarily at the undergraduate level, process performance in the context of social change, as well as apply course concepts and practices in their own performance work; and to affirm a body-centered, performative pedagogy in the classroom. Also included is a video of the live performance
