Human carrying capacity and human health

The issue of human overpopulation has fallen out of favor among most contemporary demographers, economists, and epidemiologists. Discussing population control has become a taboo topic. Yet, this taboo has major implications for public health.

The silence around overpopulation prevents the global health community from making the necessary link between the planet's limited ability to support its people (its carrying capacity—see sidebar on following page) and health and development crises. In this article, I describe how popular thinking on population control has been shaped over the last 200 years, and how our failure to address the population explosion may be one cause of recent epidemics and social unrest.

Spirituality and sexual abuse: issues and dilemmas for survivors

Sexual abuse profoundly affects survivors to the extent that they are unable to maintain previously held viewpoints or ways of being, including those relating to their spirituality. Certainly the experience has considerable potential to complicate the spiritual lives of survivors. For Christian survivors, this may include how they perceive and relate to both themselves and God as well as affect participation in sacraments such as eucharist and reconciliation. Spiritual traditions often promote the embracing of silence, but this may be problematic for survivors who have been silenced and unable to give expression to their experiences. Similarly, socialization resulting in beliefs that Christians should always forgive and/or never be angry needs to be overcome. While negotiating these pitfalls may result in explorations of spirituality being even less straightforward for survivors of sexual abuse than it is for others, a transformative spirituality within a Christian framework can be realized.

Registered nurses` lived experience of advocacy within a critical care nuit: a phenomenological study

Anecdotally, it has often been expressed by registered nurses (RNs) working within critical care environments that they are patient advocates. However, to date, little systematic research has been undertaken to validate this assertion. Thus this project, which explored the lived experience of RNs working within a critical care unit in a country area of Australia, was conceived.

The five participants of this study were all Division 1 RNs possessing a critical care certificate and a minimum of 4 years' nursing experience. Through their participation in an in-depth audiotaped interview they revealed a wealth of experiences and ideas about their involvement as patient advocates. The results of this research indicate that the phenomenon of nurse advocacy is a multi-faceted process and embraces many kinds of activities that nurses engage in on behalf of their clients.

The findings of this study indicate that some of the participants' experiences are congruent with elements of advocacy contained within the nursing literature and statements of professional nursing bodies. However, there are some findings in this study that are not consistent with available literature. For instance, these participants markedly reject the notion that advocacy is an inappropriate concept for nurses, despite suggestions in the literature that this is an inappropriate role. Instead they wholeheartedly embrace this role, asserting it as central to their practice. Further, although the literature identifies potential controversies regarding enactment of the role of advocacy, the participants of this study are silent on these matters. It is not known what this silence implies and, in light of the study findings, it is recommended that nursing organisations, theorists and clinicians consider whether it is worthwhile to more clearly confirm the nature and role of advocacy within Australian nursing.

Homophobia and the production of shame: young people and same sex attraction

Research among same-sex attracted young people in Western cultures has described a minority group of adolescents whose sexuality is negated by the significant institutions and people in their lives. Very often, there is a silence in the family and at school about same-sex sexuality and when a young person's homosexuality is suspected or disclosed s/he suffers from denial, discrimination and abuse. Not surprisingly, living in hostile environments leaves such young people at high-risk of drug abuse, depression and suicide. This paper describes some of the ways young people resist being positioned in these negative ways. Using autobiographical stories from 200 same-sex attracted young Australians, we document the discursive field of sexuality in which these young people struggle to construct positive identities. Young people were well aware of dominant discourses which characterized homosexuality as 'evil, diseased and unnatural'. Yet they use different strategies to fault, deflect and discount these negative understandings and to highlight other discourse which positions them positively.

Gay and Lesbian Life at Colby 1969-1974

The history of a gay and lesbian student community at Colby seems to point to the difficulty of visibility. For students who were able to find others like themselves, their group of lesbian and gay friends had to remain underground. For students who were grappling with their newly found, socially stigmatized sexuality, the experience was isolating if they did not know where to find others like themselves. This paper seeks to address the social forces that kept sexually variant students from expressing their sexual identities openly on campus. Part of this difficulty is attributable to the compulsory heterosexuality assumed by general American society at the time, manifested in the silence or outright hostility directed against homosexuals. Naturally, Colby students replicated this assumption. Some of the students we interviewed seemed to internalize compulsory heterosexuality, while it was forced upon others. Religion and psychology were two methods of enforcing heterosexuality that were relevant to the people we interviewed. Another significant obstacle to visibility was Colby's location and the nature of Colby's student body. Waterville, unlike more urban cities, did not have a history of gay life, and thus an established gay community or gay identity into which one could be socialized. Colby, as a small, homogeneous and isolated space, posed difficulties in establishing a gay community as the population to draw from was small and regulated.

Opening the Windows of the Church to the World: The Creation of Nostra Aetate and Its Impact on the Christian-Jewish relationship

It is important to assert that this study is not a work to inflict guilt on the Catholics or Catholicism for their silence and indifference during the Holocaust. Instead, this study is about the process of moving on from the Catholic Church's past to where the Jewish community's theological existence was finally recognized and the Jewish people were no longer seen as the Others who killed Christ. This was, achieved through a church declaration titled Nostra Aetate (In Our Time). This study records the journey traversed by this declaration, the insurmountable odds it faced in its creation until its promulgation and the impact it has on the Jewish-Christian relationship.

Conversion stories as shifting narratives of organizational change

This paper is concerned with how employees talk about their experiences of organizational change and focuses specifically on the construction of conversion stories. These are particularly positive narratives that consider change as a turning point in which individuals depart from an old way of life pre-change to embrace a post-change organization. In this study, employees seek conversion into management groups and report the values and philosophies of management in their narratives, thus highlighting the benefits of change while suppressing any negative aspects. This paper draws attention to the dramatic nature of the conversion story and explores the sharp distinction between the reporting of experiences prior to and after change. We also investigate the relationship between constructing conversion stories and gaining personal and career advancement at work and suggest that beneath the positive exterior of the conversion narratives lies a theme of silence, which may be related to career advancement. Our findings suggest that such stories of silence complicate the conversion story as an example of positive organizational change and discuss implications for both the theory and practice of narrative change research.

Bastard moon : essays on Chinese-Australian writing

A timely collection of essays and interviews which starts by exploding the myth that the earliest Chinese immigrants to Australia 'suffered in silence' and ends on a question of crucial relevance to contemporary cultural studies: How do people of various races and cultures, especially intellectuals from Third World cultures, face a globalised future increasingly dominated by Western forces and Western systems of thought?

Race, ethnicity and education in globalized times

"This book broaches what has become a noisy silence whereby conversations about race and ethnic relationships are understood as unbalanced, irrelevant or as too dangerous to speak about. It is concerned with the ways that race and ethnic relationships are spoken about in contemporary western societies such as Australia and the changed and confused debates that underpin those discussions. Parents and teachers at one State secondary school in Melbourne, Australia speak about race and ethnic relationships as their school community is increasingly altered by globalising, technological and population change. Newspapers and public policy debates avoid discussions about race relationships even as discussions about national identity and direction are crucial themes. This book argues that race and ethnic relationships must be understood in new ways; that the analytical frameworks provided by constructivist thought and post-colonial writing must be interrogated to provide more comprehensive methodological resources to examine these relationships."

Is sex-specific mass gain in Cory's shearwaters Calonectris diomedea related to begging and steroid hormone expression?

Mass differences between the sexes of dimorphic bird species often appear early in the nestling development. But how do adults know how much to feed a chick in a sexually dimorphic species? Do chicks of the heavier sex beg more? We studied begging in Cory’s shearwaters Calonectris diomedea, a species with heavier adult and juvenile males than females. We found that begging rates and call numbers were not different between male and female chicks, but parameters of begging intensity differed between the sexes in their relationship to chick body condition. For the same body condition, males had significantly higher begging call numbers and rates. Acoustical parameters, which were analysed semi-automatically, included the lengths of call and silence intervals, the minimum, mean and maximum frequency in a call and the number of frequency peaks within a call. We found no consistent differences of acoustic begging call elements between the sexes. Male and female chicks did not differ in the levels of the steroid hormones testosterone or corticosterone in the second quarter of the nestling period, and the mechanism leading to sex-related differences in begging rates for a given body condition remains unknown.

Investigation into the diffusion of innovation in technical and further education : implementing e-mail through action research

This research project examined the diffusion of change within one Victorian TAFE Institute by engaging action research to facilitate implementation of e-mail technology. The theoretical framework involving the concepts of technology innovation and action research was enhanced with the aid of Rogers's (1983) model of the diffusion of the innovation process. Political and cultural factors made up the initiation phase of innovation, enabling the research to concentrate on the implementation phase of e-mail Roger's (1983) model also provided adopter categories that related to the findings of a Computer Attitude Survey that was conducted at The School of Mines and Industries Ballarat (SMB), now the University of Ballarat—TAFE Division since amalgamation on 1st January 1998. Despite management rhetoric about the need to utilise e-mail, Institute teaching staff lacked individual computers in their work areas and most were waiting to become connected to the Internet as late as 1997. According to the action research reports, many staff were resistant to the new e-mail facilities despite having access to personal computers whose numbers doubled annually. The action research project became focussed when action researchers realised that e-mail workshop training was ineffective and that staff required improved access. Improvement to processes within education through collaborative action research had earlier been achieved (McTaggart 1994), and this project actively engaged practitioners to facilitate decentralised e-mail training in the workplace through the action research spiral of planning, acting, observing and reflecting, before replanning. The action researchers * task was to find ways to improve the diffusion of e-mail throughout the Institute and to develop theoretical constructs. My research task was to determine whether action research could successfully facilitate e-mail throughout the Institute. A rich literature existed about technology use in education, technology teaching, gender issues, less about computerphobia, and none about 'e-mailphobia \ It seemed appropriate to pursue the issue of e-mailphobia since it was marginalised, or ignored in the literature. The major political and cultural influences on the technologising of SMB and e-mail introduction were complex, making it impossible to ascertain the relative degrees of influence held by Federal and State Governments, SMB's leadership or the local community, Nonetheless, with the implementation of e-mail, traditional ways were challenged as SMB's culture changed. E-mail training was identified as a staff professional development activity that had been largely unsuccessful. Action research is critical collaborative inquiry by reflective practitioners who are accountable for making the results of their inquiry public and who are self-evaluating of their practice while engaging participative problem-solving and continuing professional development (Zuber-Skerritt 1992, 1993). Action research was the methodology employed in researching e-mail implementation into SMB because it involved collaborative inquiry with colleagues as reflective practitioners. Thoughtful questions could best be explored using deconstructivist philosophy, in asking about the noise of silence, which issues were not addressed, what were the contradictions and who was being marginalised with e-mail usage within SMB. Reviewing literature on action research was complicated by its broad definition and by the variability of research (King & Lonnquist 1992), and yet action research as a research methodology was well represented in educational research literature, and provided a systematic and recognisable way for practitioners to conduct their research. On the basis of this study, it could be stated that action research facilitated the diffusion of e-mail technology into one TAFE Institute, despite the process being disappointingly slow. While the process in establishing the action research group was problematic, action researchers showed that a window of opportunity existed for decentralised diffusion of e-mail training,in preference to bureaucratically motivated 'workshops. Eight major findings, grouped under two broad headings were identified: the process of diffusion (planning, nature of the process, culture, politics) and outcomes of diffusion (categorising, e-mailphobia, the survey device and technology in education). The findings indicated that staff had little experience with e-mail and appeared not to recognise its benefits. While 54.1% did not agree that electronic means could be the preferred way to receive Institute memost some 13.7% admitted to problems with using the voice answering service on telephones. Some 43.3% thought e-mail would not improve their connectedness (how they related) to the Institute. A small percentage of staff had trouble with telephone voice-mail and a number of these were anxious computer users. Individualised tuition and peer support proved helpful to individual staff whom action researchers believed to be 'at risk', as determined from the results of a Computer Attitude Survey. An instructional strategy that fostered the development of self-regulation and peer support was valuable, but there was no measure of the effects of this action research program, other than in qualitative terms. Nevertheless, action research gave space to reflect on the nature of the underlying processes in adopting e-mail. Challenges faced by TAFE action researchers are integrally affected by the values within TAFE, which change constantly and have recently been extensive enough to be considered as a 'new paradigm'. The influence of competition policy, the training reform agenda and technologisation of training have challenged traditional TAFE values. Action research reported that many staff had little immediate professional reason to use e-mail Theoretical answers were submerged beneath practical professional concerns, which related back to how much time teachers had and whether they could benefit from e-mail. A need for the development of principles for the sound educational uses of e-mail increases with the internationalisation of education and an increasing awareness of cultural differences. The implications for conducting action research in TAFE are addressed under the two broad issues of power and pedagogy. Issues of power included gaining access, management's inability to overcome staff resistance to technology, changing TAFE values and using technology for conducting action research. Pedagogical issues included the recognition of educational above technological issues and training staff in action research. Finally, seventeen steps are suggested to overcome power and pedagogical impediments to the conduct of action research within TAFE. This action research project has provided greater insight into the difficulties of successfully introducing one culture-specific technology into one TAFE Institute. TAFE Institutes need to encourage more action research into their operations, and it is only then that -we can expect to answer the unanswered questions raised in this research project.

Communicating the 'unspeakability' of violent acts in cinema

This paper explores the forensic testimony employed in James Benning‟s experimental narrative film Landscape Suicide (1986, 16mm, 95min USA). As a belated example of Judith Walker‟s „Trauma Cinema‟, this film in part re-enacts the court transcripts of two perpetrators of physical violence: Ed Gein and Michelle Protti. Teenager Protti killed another student with a kitchen knife after having been subjected to bullying by a group of girls and Wisconsin farmer Gein shot a storekeeper‟s wife, took the body home to then skin and dissect it. Gein‟s case is said to have provided the model for the cinematic serial killers portrayed in Psycho (1959), The Silence of the Lambs (1991) and Texas Chainsaw Massacre (1974). In its strategy of communicating or representing the overwhelming and traumatic impact of violence cinematically Landscape Suicide is contrasted to the melodrama and shock of mainstream violence in Psycho, Texas Chainsaw Massacre and Silence of the Lambs for its ability to identify „unspeakable‟ aspects of overwhelming experience. This paper will concentrate on the representation of Ed Gein‟s violent acts, rather than Protti‟s and enlists recent neurological research that suggests a model for forgetting that is identifiable in the film‟s structure and content.

Surrender to the market : thoughts on anthropology, the body shop, and intellectuals

The direction of anthropology over the last century is tied to the shifts from colonialism to postcolonialism and from modernism to postmodernism. These shifts have seen the thoroughgoing incorporation of the world population into the economic, political and juridical domain established through the last throes of colonialism and the transmutations of capitalism and the State. Anthropology, a discipline whose history shows close and regular links with colonial government, also transforms in association with the world it describes and partly creates. Two dominant trends in contemporary anthropology--applied consultancy and historicist self-reflexivity--are compared for the ways they represent the transmutation, which is characterised, following Fredric Jameson as 'the surrender to the market'. In this way it is asserted that just as the discipline had hitherto revealed its links to colonialism, it now reveals its links to globalisation through a form of commodified self-obsession. To illustrate this quality the paper considers the global chain of cosmetics stores, The Body Shop, as an example of 'late capitalism' and the moral juridical framework of globalisation. Finally, it treats these developments in anthropology as more generally affecting intellectuals and knowledge production through the promotion of intellectual 'silence'.

Molecular genetics and comparative genomics reveal RNAi is not functional in malaria parasites

Techniques for targeted genetic disruption in Plasmodium, the causative agent of malaria, are currently intractable for those genes that are essential for blood stage development. The ability to use RNA interference (RNAi) to silence gene expression
would provide a powerful means to gain valuable insight into the pathogenic blood stages but its functionality in Plasmodium remains controversial. Here we have used various RNA-based gene silencing approaches to test the utility of RNAi in malaria
parasites and have undertaken an extensive comparative genomics search using profile hidden Markov models to clarify whether RNAi machinery
exists in malaria. These investigative approaches revealed that Plasmodium lacks the enzymology required for RNAi-based ablation of gene expression
and indeed no experimental evidence for RNAi was observed. In its absence, the most likely explanations for previously reported RNAi-mediated knockdown are either the general toxicity of introduced RNA (with global down-regulation of gene expression) or a specific antisense effect mechanistically distinct from RNAi, which will need systematic
analysis if it is to be of use as a molecular genetic tool for malaria parasites.

Mediated hegemony : interference in the post-Saddam Iraqi media sector

The toppling of Saddam in 2003 brought with it the re-emergence of the free press in Iraq. This has seen Iraq shift from only a handful of state media outlets that served as propaganda machines, to a vast array of Iraqi-owned newspapers, radio stations and television channels which are being fervently produced and avidly consumed across the nation. As is to be expected, there are several problems that have accompanied such a divergent, ad-hoc and highly volatile media landscape. Leaving aside important issues such as the dangers faced by Iraqi journalists and the lack of appropriate press laws, this paper focuses instead on the influence of both foreign and domestic political bodies on the post-Saddam Iraqi media sector. Among the foreign influences are Iran, Saudi Arabia and the United States, all of which fund, control and manipulate various Iraqi media outlets. Not surprisingly, the United States has been the most active, using both overt and clandestine propaganda methods as well as forced closure to control the Iraqi media sector. Unfortunately, such measures are not limited to those governments which exist outside Iraq’s borders, with both the Iraqi government and the Kurdish regional authority having used similar means to control and even silence Iraq’s nascent public sphere. This paper concludes by noting the irony of limiting press freedoms in Iraq during this crucial phase in its transition from despotism to democracy.
