Effect of demographic variables on public attitudes towards genetically modified insulin

Earlier studies on public attitude and risk perception have concluded that the public’s attitudes towards biotechnology was primarily driven by several factors such as familiarity, perceived benefits, perceived risks, risk acceptance, moral concerns and encouragement. Demographic characteristics have been known to affect attitudes towards science. The purpose of this paper is to compare the attitude of the Malaysian public towards genetically modified (GM) insulin across several background variables such as religion, race, education level and age. A survey was carried out on 1017 respondents stratified according to various stakeholder groups in the Klang Valley region. Analyses of Variance (ANOVAs) showed significant differences in the mean scores for familiarity of GM insulin across religions, races and ages but not across education levels and gender. Both perceived benefits and perceived risks were found to differ across races, education levels and gender but not across religions and ages. On the other hand, moral concern was found to differ in all four background variables except gender while risk acceptance differed across races and gender and encouragement only differed across education  levels. In conclusion, background variables do have a significant effect on some of the dimensions of Malaysians’ attitudes towards modern biotechnology. The research findings will be useful for understanding the effect of background variables on public attitudes towards the application of gene technology in medicine. More in-depth empirical studies should be carried out to understand the underlying causes behind the differences.Key words: Attitude, gene technology, medicine, GM (genetically modified) insulin, background variables, Malaysia

Land sparing versus land sharing:Moving forward

To address the challenges of biodiversity conservation and commodity production, a framework has been proposed that distinguishes between the integration (land sharing) and separation (land sparing) of conservation and production. Controversy has arisen around this framework partly because many scholars have focused specifically on food production rather than more encompassing notions such as land scarcity or food security. Controversy further surrounds the practical value of partial trade-off analyses, the ways in which biodiversity should be quantified, and a series of scale effects that are not readily accounted for. We see key priorities for the future in (1) addressing these issues when using the existing framework, and (2) developing alternative, holistic ways to conceptualise challenges related to food, biodiversity, and land scarcity

Tumour brain: pre‐treatment cognitive and affective disorders caused by peripheral cancers

People that develop extracranial cancers often display co-morbid neurological disorders, such as anxiety, depression and cognitive impairment, even before commencement of chemotherapy. This suggests bidirectional crosstalk between non-CNS tumours and the brain, which can regulate peripheral tumour growth. However, the reciprocal neurological effects of tumour progression on brain homeostasis are not well understood. Here, we review brain regions involved in regulating peripheral tumour development and how they, in turn, are adversely affected by advancing tumour burden. Tumour-induced activation of the immune system, blood–brain barrier breakdown and chronic neuroinflammation can lead to circadian rhythm dysfunction, sleep disturbances, aberrant glucocorticoid production, decreased hippocampal neurogenesis and dysregulation of neural network activity, resulting in depression and memory impairments. Given that cancer-related cognitive impairment diminishes patient quality of life, reduces adherence to chemotherapy and worsens cancer prognosis, it is essential that more research is focused at understanding how peripheral tumours affect brain homeostasis

Assessing the economic impacts of crises: A decision-support approach to long-term strategic planning

The assessment of economic impacts of crises and risk reduction generated by different mitigation measures is a multidimensional problem and often a challenging task. A major issue hindering the process is a lack of structured information. In particular, intangible losses are difficult to evaluate monetarily. Furthermore, the uncertainty related to the operational environment is difficult to estimate. This paper proposes a practical economic approach that aims at assessing different measures to mitigate the impacts of the crises. The purpose is to contribute to the understanding of the decision-making related to crisis management so that the goals of the decisions can be reached. The approach is mainly aimed at enhancing decision-making on a strategic level and at supporting crisis-management training. Additionally, a software tool based on the approach will be developed to make the assessment procedure usable in practice. The approach is demonstrated in two pilot cases: extreme winter storm in North of Finland and a major earthquake in Italy. The paper is based on research carried out in the CRISMA integration project which is funded by the European Community's Seventh Framework Programme. © 2014 WIT Press

Putting meaning back into “sustainable intensification”

In light of human population growth, global food security is an escalating concern. To meet increasing demand for food, leading scientists have called for "sustainable intensification", defined as the process of enhancing agricultural yields with minimal environmental impact and without expanding the existing agricultural land base. We argue that this definition is inadequate to merit the term "sustainable", because it lacks engagement with established principles that are central to sustainability. Sustainable intensification is likely to fail in improving food security if it continues to focus narrowly on food production ahead of other equally or more important variables that influence food security. Sustainable solutions for food security must be holistic and must address issues such as food accessibility. Wider consideration of issues related to equitable distribution of food and individual empowerment in the intensification decision process (distributive and procedural justice) is needed to put meaning back into the term "sustainable intensification"
