'Affective eduscapes': the case of Indian students within Australian international higher education
No full textIn this article we examine the financial, cultural and governmental structures that frame international education as an important part of Appudurai’s ethnoscapes of globalization. Developing the idea of affective eduscapes we analyse the lived experiences of Indian students. Drawing on interview material, we deconstruct the idea of ‘the Indian student’, and any singular experience of international higher education.
Real options in management and organizational strategy: a review of decision-making and performance implications
No full textThis paper contributes to the debate on the role of real options theory in business strategy and organizational decision-making. It analyses and critiques the decisionmaking and performance implications of real options within the management theories of the (multinational) firm, reviews and categorizes the organizational, strategic and operational facets of real options management in large business settings. It also presents the views of scholars and practitioners regarding the incorporation and validity of real options in strategy, international management and business processes1. The focus is particularly on the decision-making and performance attributes of the real options logic concerning strategic investments, governance modes and multinational operations management. These attributes are examined from both strategic and operating perspectives of decision-making in organizations, also with an overview of the empirical evidence on real options decision-making and performance.

No full textEvolution of the TSC1/TSC2-TOR signaling pathway
No full textThe TSC1/TSC2-TOR signaling pathway [the signaling pathway that includes the heterodimeric TSC1 (tuberous sclerosis 1 protein)–TSC2 (tuberous sclerosis 2 protein) complex and TOR (target of rapamycin)] regulates various cellular processes, including protein synthesis, in response to growth factors and nutrient availability. Homologs of some pathway components have been reported from animals, fungi, plants, and protozoa. These observations led to the perception that the whole pathway is evolutionarily conserved throughout eukaryotes. Using complete genome sequences, we show that, contrary to this view, the pathway was built up from a simpler one, present in the ancestral eukaryote, coupling cell growth to energy supplies. Additional elements, such as TSC1 and TSC2, were "bolted on" in particular eukaryotic lineages. Our results also suggest that unikonts [Opisthokonta (including animals and fungi) and Amoebozoa] form a monophyletic group with the Excavata and Chromalveolata. A previous proposal, that the root of the eukaryotic "tree of life" lies between the unikonts and other organisms, should therefore be reevaluated.
Proactive coping in community-dwelling older Australians
No full textThis article reports on a study of older community-dwelling Australian adults which aimed to test whether a relatively unexplored construct, proactive coping, could have a role in purpose in life, personal growth, and life satisfaction. A total of 109 women and 115 men (Mean age = 75.04 yrs, SD = 6.66) completed a questionnaire containing Greenglass et al.'s (1999) Proactive Coping Inventory, the Purpose in Life and Personal Growth subscales of Ryff's (1989) Psychological Well-being Scales, and the Satisfaction with Life Scale (Diener et al., 1985). The results of hierarchical multiple regression analyses indicated that proactive coping was a highly significant predictor of all three measures of well-being, after controlling for age and health. The effect on personal growth and purpose in life was particularly strong. Proactive coping does seem to be an important variable in the psychological well-being of older adults. However, the correlational nature of the design, and the likelihood of some conceptual overlap between the well-being variables, suggest that these inferences can only be tentative. Designing psychological interventions to improve proactive coping may help to improve quality of life at older ages. There is a need for experimental research to further explore the causal influence of proactive coping and for further theoretical work to determine the exact nature of proactive coping.
Satisfying privacy requirements : one step before anonymization
No full textIn this paper, we study a problem of privacy protection in large survey rating data. The rating data usually contains both ratings of sensitive and non-sensitive issues, and the ratings of sensitive issues include personal information. Even when survey participants do not reveal any of their ratings, their survey records are potentially identifiable by using information from other public sources. We propose a new (k,ε,l)-anonymity model, in which each record is required to be similar with at least k − 1 others based on the non-sensitive ratings, where the similarity is controlled by ε, and the standard deviation of sensitive ratings is at least l. We study an interesting yet nontrivial satisfaction problem of the (k,ε,l)-anonymity, which is to decide whether a survey rating data set satisfies the privacy requirements given by users. We develop a slice technique for the satisfaction problem and the experimental results show that the slicing technique is fast, scalable and much more efficient in terms of execution time than the heuristic pairwise method.
