Human carrying capacity and human health

The silence around overpopulation prevents the global health community from making the necessary link between the planner's limited ability to support its people and health and development crises. The author describes how popular thinking on population control has been shaped over the last 200 years and how out failure to address the population explosion may be one cause of recent epidemics and social unrest.

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.

Towards a framework for exploring children's analytical thinking and creativity in technology

Technology education provides children with opportunities to be creative as they engage in problem solving and make products that address human needs. When thinking creatively, children generate new ideas through remote associations and brainstorming and this type of thinking is enhanced when attention is allowed to wander in a relaxed and uncompetitive environment. Research shows that the two mental states (generative and nongenerative/analytical) cannot exist simultaneously (Howard-Jones 2002). It follows that at some point in the technological process a child’s generative mental state needs to give way to a nongenerative, analytical state so that the child can focus on analysing information. This research project aims to investigate the impact of analytical thinking on creativity in the context of technology education in young children.

Health promotion and climate change : exploring the core competencies required for action

Climate change poses serious threats to human health and well-being. It exacerbates existing health inequities, impacts on the social determinants of health and disproportionately affects vulnerable populations. In the Australian region these include remote Aboriginal communities, Pacific Island countries and people with low incomes. Given health promotion’s remit to protect and promote health, it should be well placed to respond to emerging climate-related health challenges. Yet, to date, there has been little evidence to demonstrate this. This paper draws on the findings of a qualitative study conducted in Victoria, Australia to highlight that; while there is clearly a role for health promotion in climate change mitigation and adaptation at the national and international levels, there is also a need for the engagement of health promoters at the community level. This raises several key issues for health promotion practice. To be better prepared to respond to climate change, health promotion practitioners first need to re-engage with the central tenets of the Ottawa Charter, namely the interconnectedness of humans and the natural environment and, secondly, the need to adopt ideas and frameworks from the sustainability field. The findings also open up a discussion for paradigmatic shifts in health promotion thinking and acting in the context of climate change.

To boldly go where no one has gone before: symbolic annihilation and queer interventions in the Star Trek universe

Despite queer readings and interpretations by scholars and fans alike, the official Star Trek universe is devoid of any concrete or obvious representation of LGBTIQ identities. While this appears to be a case of symbolic annihilation, two recent episodes of the Internet series Star Trek New Voyages: Phase II (2004–, webseries), titled ‘Blood and Fire: Part One’ and ‘Blood and Fire: Part Two’, finally go where official Star Trek texts could, or would, not. Taking up the dual perspective of both fan and scholar, in this article I argue that these episodes use the conspicuous absence of representations of sexual diversity in the Star Trek franchise proper as the impetus for a creative intervention, one that embodies the capacity of science fiction texts to explore human sexuality beyond the confines of heteronormative identities.

Holding the purse strings : the continuing evolution of human rights law and the potential liability of the finance industry for human rights abuses

While the responsibility of States and, in more recent times, corporations, has been thoroughly discussed in relation to human right~, a new stage of evolution may be emerging in relation to the liability of the financial backers of an enterprise that is accused of human rights abuses. This article considers the basis in international law for such emerging liability and examines some of the legal avenues used in recent domestic litigation against financial institutions. The article concludes by examining some of the relevant instruments of 'soft' international law and notes that although there is little in the way of concrete legislation or judicial precedent that would hold financial institutions responsible for the actions of those they invest in, the potential for the law to evolve in that direction is clear.

E-Commerce, human resource strategies, and competitive advantage: two Australian banking case studies

Service organizations need to consider in depth the human resource management (HRM) strategies that will enable them to achieve sustained competitive advantage in the e-commerce era. This paper analyzes the HRM strategies developed to accommodate the changing customer service practices associated with B2C e-commerce in the retail banking sector. Based on case study data, it describes how two banks in Australia, one large, the other small, have linked their e-commerce strategies with their overall business strategy, and the extent to which their HRM strategies have helped them to utilize their e-commerce capability to achieve sustained competitive advantage.

Intraspecific phenotypic variability in the black-eared miner (Manorina melanotis); human-facilitated introgression and the consequences for an endangered taxon

Prior to this study the circumscription of the endangered black-eared miner (Manorina melanotis) and the common yellow-throated miner (Manorina flavigula) has been clouded by the existence of hybrid individuals. We examined the intra- and inter-specific phenotypic variation of the two taxa. All available museum specimens (n=138) and a sample of live individuals (n=83) were examined. Cluster analysis revealed a continuum of phenotypic traits now exists between the two taxa. However, further analysis revealed the black-eared miner and yellow-throated miner were separable on phenotypic characters prior to extensive modification of mallee habitat after 1950, suggesting the black-eared miner should be afforded full species status [contrary to Schodde and Mason, 1999. (Schodde, R., Mason, I.J., 1999. The Directory of Australian Birds: Passerines. CSIRO Wildlife and Ecology, Canberra]. Our study highlights the need to carefully examine, not only intraspecific phenoptyic variation within a taxon, but to also consider how such variation may be affected by hybridisation facilitated by human disturbance of habitat.

The glue that binds : workplace climate, human resource systems and performance

There is now a substantial body of research examining the relationship between human resources (HR) and organisational performance. During the last decade, this research has focused on the impacts of ‘bundles’ of HR practices. While researchers have consistently found a significant relationship between HR systems and performance, the mechanisms that give rise to this relationship remain poorly conceptualised. Building on the work of Barney (1998), Ferris et al. (1998) and Bowen and Ostroff (2004) we suggest the social context in which such practices are implemented provide the basis for specifying these transmission mechanisms. Workplace climate provides a key social context that induces high levels of effort and dynamic efficiency. Using a large sample we find workplace climate significantly influences the relationship between HR systems and performance.
