Influence of social network structure on entrepreneurship participation — a study of 20 national

By investigating differences in social networks among entrepreneurs in 20 cultures, this paper contributes to the debate on whether there is universality in the process of entrepreneurial networking. Representative samples of entrepreneurs were identified in the same manner in 20 countries from 2000 to 2004 (N=€‰304,560). The sampling methodologies and the questions asked were similar across all countries. Logistic regression was used to test for significant regional interaction effects involving personally knowing an entrepreneur. Results are contrary to the existence of any mono-dimensional form of networking practice but do strongly support the existence of both variform universality (culture moderates the importance of networking) and functional universality (cultural similarities in networking practice exist).

The emergence of the global workplace : opportunities and barriers for building surveyors in Oceania

The Royal Institution of Chartered Surveyors (RICS) the professional body representing surveyors in the UK, has implemented a policy to globalise in order to meet the challenges and opportunities the global marketplace was creating for its members as well as protecting and serving its interests (RICS, 1999). Quantity surveyors had a presence and history of employment outside the UK, particularly in the Middle and Far East. Real estate surveyors found the transition to working in European Union (EU) countries relatively straightforward and numerous UK real estate organisations have European, Asian, North American and Oceanic offices. Additionally UK based firms establishing partnerships with overseas real estate firms expanded significantly over the previous decade. Building Surveying is different. Small numbers worked in commonwealth countries but in most countries their professional and academic qualifications were not recognised. With the changes implemented by the RICS, this paper examines the barriers and opportunities facing RICS Chartered Building Surveyors (CBS) in Oceania (taken as Australia, New Zealand, Papua New Guinea and Fiji).

A desk top study reviewed the political, economic and sociological variables affecting employment opportunities and professional services which were put to the RICS Oceania Building Surveying Faculty. No previous study had been undertaken to identify the specific barriers and opportunities in Oceania for the BS and this research adopted a census survey of RICS practitioners currently employed in the region and the results form the most comprehensive picture of the current position. The findings are that some of the opportunities and barriers will change in significance over time. The main barriers to growth were perceived as lack of support from a Euro focussed RICS and the difficulties associated with being perceived as outsiders. Opportunities were perceived as emerging in new areas of professional services such as sustainability and energy efficiency.

No va sobre la sangre. Operacion puerto y el fin de la modernidad

EI caso espanol de dopaje conocido como "Operaci6n Puerto" queda enmarcado dentro del
abandono de las antiguas concepciones legales y la construcci6n de un nuevo sistema funcional de alcance global. "Operaci6n Puerto" ilustra el temor de Verner Moeller de que la politica anti dopaje senala el final de la modernidad - donde se elabora y aplica la ley tanto en los tribunales como en los medios de comunicaci6n. OP es el ejemplo perfecto de la distancia existente entre la ret6rica de la crisis mediatica que rodea al dopaje y al ciclismo profesional y la verdadera realidad de los procesos materiales que tienen lugar mientras el ciclismo atraviesa por un proceso global de reajuste estructural y de construcci6n de una nueva cartografla global del ciclismo. La legitimidad se obtiene a traves de la gesti6n de las crisis y de los acontecimientos: la excepci6n, la funcionalidad y el espectaculo bajo una apariencia de guerra justa contra el mal del dopaje

Continuous product innovation : learning behaviours and knowledge management

The research reported in this paper considers Product Innovation from a broader perspective than that of the isolated NPD (New Product Development) project commonly discussed in the literature. In this perspective, Product Innovation is a continuous and cross-functional process involving the sharing and transfer of knowledge within the many steps of the innovation process, and the integration of a growing number of different competencies inside and outside the organisational boundaries. This paper examines two in-depth case studies that were carried out to establish if and how learning occurred within companies developing new products. Based on a model developed as part of a joint Euro-Australian research project, the way in which the selected companies share and transfer knowledge and learning experiences during their product innovation processes have been examined and analysed. This model uses a number of interrelated variables including performance, behaviours and levers to stimulate improvement, contingencies, and learning/innovation capabilities to describe the learning and knowledge transfer in product innovation processes within the case studies. This paper discusses some of the skills the research has identified that managers need to enable their companies to gain a competitive advantage through improved product innovation. The ongoing research has developed, tested and disseminated a computer-based methodology to assess organisational knowledge capture and transfer in the new product development process. The research is part of the Euro-Australian co-operation project known as CIMA (Continuous Improvement and Product Innovation Management).

Knowledge management in continuous product innovation : a contingent approach

There is a growing interest in new organisational forms and integrated managerial and technological approaches supporting companies in continuously innovating their products and processes to survive in a turbulent environment. Successful product innovation will more and more depend upon a company's ability to manage knowledge and integrate a growing number of competencies within and outside the organisational boundaries. These abilities require a complex set of interrelated managerial, technological and organisational conditions that must be designed according to the individual firm's characteristics. This paper aims to identify and analyse the relation between individual firms' contingent variables and managerial approaches to foster knowledge management in product innovation. Evidence is based on a survey of 70 companies, including European and Australian firms, developed within the Euro-Australian cooperation project entitled CIMA (Continuous Improvement for global innovation management).

Intercultural relations in a global world

The exploration of cross-cultural contact in a global and transnational world is essential for understanding how we can learn to live with difference in ways that go beyond tolerance. This book explores such contact in Euro-American/Australian societies as well as non-western multiethnic societies such as China, Malaysia, Indonesia and countries within Easter Europe. The contributors in this book expose the power relations underpinning such encounters as well as explore the possibilities for meaningful dialogue.

Connectivity, online social capital, and mood : a Bayesian nonparametric analysis

Social capital indicative of community interaction and support is intrinsically linked to mental health. Increasing online presence is now the norm. Whilst social capital and its impact on social networks has been examined, its underlying connection to emotional response such as mood, has not been investigated. This paper studies this phenomena, revisiting the concept of “online social capital†in social media communities using measurable aspects of social participation and social support. We establish the link between online capital derived from social media and mood, demonstrating results for different cohorts of social capital and social connectivity. We use novel Bayesian nonparametric factor analysis to extract the shared and individual factors in mood transition across groups of users of different levels of connectivity, quantifying patterns and degree of mood transitions. Using more than 1.6 million users from Live Journal, we show quantitatively that groups with lower social capital have fewer positive moods and more negative moods, than groups with higher social capital. We show similar effects in mood transitions. We establish a framework of how social media can be used as a barometer for mood. The significance lies in the importance of online social capital to mental well-being in overall. In establishing the link between mood and social capital in online communities, this work may suggest the foundation of new systems to monitor online mental well-being.

Credit cycle dependent spread determinants in emerging sovereign debt markets

We address credit cycle dependent sovereign credit risk determinants. In our model, the spread determinants' magnitude is conditional on an unobservable endogenous sovereign credit cycle as represented by the underlying state of a Markov regime switching process. Our explanatory variables are motivated in the tradition of structural credit risk models and include changes in asset prices, interest rates, implied market volatility, gold price changes and foreign exchange rates. We examine daily frequency variations of U.S. dollar denominated Eurobond credit spreads of four major Latin American sovereign bond issuers (Brazil, Colombia, Mexico and Venezuela) with liquid bond markets during March 2000 to June 2011. We find that spread determinants are statistically significant and consistent with theory, while their magnitude remarkably varies with the state of the credit cycle. Crisis states are characterized by high spread change uncertainty and high sensitivities with respect to the spread change determinants. We further document that not only changes of local currencies, but also changes of the Euro with respect to the U.S. dollar are significant spread drivers and argue that this is consistent with the sovereigns' ability to pay.

Attributable risk analysis reveals potential healthcare savings from increased consumption of dairy products.

With rising burdens of obesity and chronic disease, the role of diet as a modifiable risk factor is of increasing public health interest. There is a growing body of evidence that low consumption of dairy products is associated with elevated risk of chronic metabolic and cardiovascular disorders. Surveys also suggest that dairy product consumption falls well below recommended targets for much of the population in many countries, including the USA, UK, and Australia. We reviewed the scientific literature on the health effects of dairy product consumption (both positive and negative) and used the best available evidence to estimate the direct healthcare expenditure and burden of disease [disability-adjusted life years (DALY)] attributable to low consumption of dairy products in Australia. We implemented a novel technique for estimating population attributable risk developed for application in nutrition and other areas in which exposure to risk is a continuous variable. We found that in the 2010-2011 financial year, AUD$2.0 billion (USD$2.1 billion, €1.6 billion, or ∼1.7% of direct healthcare expenditure) and the loss of 75,012 DALY were attributable to low dairy product consumption. In sensitivity analyses, varying core assumptions yielded corresponding estimates of AUD$1.1-3.8 billion (0.9-3.3%) and 38,299-151,061 DALY lost. The estimated healthcare cost attributable to low dairy product consumption is comparable with total spending on public health in Australia (AUD$2.0 billion in 2009-2010). These findings justify the development and evaluation of cost-effective interventions that use dairy products as a vector for reducing the costs of diet-related disease.

The microbiological and sustainability effects of washing anaesthesia breathing circuits less frequently

In the presence of single-use airway filters, we quantified anaesthetic circuit aerobic microbial contamination rates when changed every 24 h, 48 h and 7 days. Microbiological samples were taken from the interior of 305 anaesthetic breathing circuits over a 15-month period (3197 operations). There was no significant difference in the proportion of contaminated circuits when changed every 24 h (57/105 (54%, 95% CI 45–64%)) compared with 48 h (43/100 (43%, 95% CI 33–53%, p = 0.12)) and up to 7 days (46/100 (46%, 95% CI 36–56%, p = 0.26)). Median bacterial counts were not increased at 48 h or 7 days provided circuits were routinely emptied of condensate. Annual savings for one hospital (six operating theatres) were $AU 5219 (£3079, €3654, $US 4846) and a 57% decrease in anaesthesia circuit steriliser loads associated with a yearly saving of 2760 kWh of electricity and 48 000 l of water. Our findings suggest that extended circuit use from 24 h up to 7 days does not significantly increase bacterial contamination, and is associated with labour, energy, water and financial savings.

Everyday multiculturalism: Catching the bus in Darwin, Australia

Following acts of violence in major cities, the future of multiculturalism as a philosophy and a state-sponsored policy to promote peace and interdependence in white majority societies seem uncertain. Ethnographic research that explores the lived experience of multiculturalism in shared public spaces, however, offers the possibility to explore emotional stress as well as possibilities for change in culturally diverse cities. Within this literature, however, there is little grounded research that explores Indigenous-ethnic minority relationships. This paper foregrounds and describes a seemingly mundane event such as catching a bus that entangles my body with an Aboriginal woman and a migrant woman from Fiji in Darwin, Australia. The paper demonstrates how injury, anger, shame and discomfort unfolds when bodies of colour are sites of stress. I explore the emergence of this bodily stress that has outcomes for the capacity of racially differentiated bodies of colour to respond ethically in encounters with strangers. I argue that thick descriptions of events, conceptualisations of agency as distributed and broader understandings of the social have the potential to contribute to anti-racist agendas in Euro-colonial societies with separate Indigenous and multicultural policy frameworks in ways that do not require bodies to 'accumulate' or 'inhabit' whiteness. © 2014 © 2014 Taylor & Francis.

Young people, pleasure, and the normalization of pornography: sexual health and well-being in a time of proliferation?

It has been argued that pornography is the most prominent sex educator for young people today (Flood, M. (2010). Young men using pornography. In E. Boyle (Ed.), Everyday Pornography (pp. 164–178). Oxford: Routledge). Research indicates that first exposure to pornography can be as young as 11 years of age. There is evidence that exposure to pornography is shaping young people’s sexual expectations and practices (H€aggstro ̈ m-Nordin et al. 2005). Many young people are learning what sex looks like from what they – or their partner or peers – observe in pornography. Significantly,pornography is normalizing sex acts that most women do not enjoy and may experience as degrading, painful, or violating. This raises serious implications for young people’s capacity to develop a sexuality that incorporates mutual pleasure, respect, and negotiation of free and full consent.While the results are complex and nuanced, research into the effects of pornography consumption provides reliable evidence that exposure to pornography increases aggressive attitudes and behavior towards women for some viewers (Malamuth et al. Annual Review of Sex Research 11, 26–91, 2000). Pornography consumption also has been found to be associated with sexual health risk taking and can impact negatively on body image and sense of self (Dean, L. (2007). Young Men, Pornography and Sexual Health Promotion, MA Research, Brighton University, Brighton, in possession of the author), and as such is a serious health and well-being issue, particularly for young women.This chapter explores preservice teachers’ reactions to pornography education using two examples from teaching of an elective Teaching Sexuality in the Middle Years, in 2011. These examples explore the complex emotions such teaching can generate and the challenges faced by preservice teachers when they are encouraged to confront the gendered and violent consequences of the normalization of pornography in a coeducational setting.

Heterogeneity of miR-10b expression in circulating tumor cells

Circulating tumor cells (CTCs) in the blood of cancer patients are recognized as important potential targets for future anticancer therapies. As mediators of metastatic spread, CTCs are also promising to be used as € liquid biopsyto aid clinical decision-making. Recent work has revealed potentially important genotypic and phenotypic heterogeneity within CTC populations, even within the same patient. MicroRNAs (miRNAs) are key regulators of gene expression and have emerged as potentially important diagnostic markers and targets for anti-cancer therapy. Here, we describe a robust in situ hybridization (ISH) protocol, incorporating the CellSearch ® CTC detection system, enabling clinical investigation of important miRNAs, such as miR-10b on a cell by cell basis. We also use this method to demonstrate heterogeneity of such as miR-10b on a cell-by-cell basis. We also use this method to demonstrate heterogeneity of miR-10b in individual CTCs from breast, prostate and colorectal cancer patients.

Propaganda política e comercial: algumas aproximações

A propaganda política e a comercial (ou publicidade) sempre tiveram conexões entre si. Com a Revolução Industrial consolida-se a propaganda comercial, enquanto a propaganda política moderna tem grande impulso na década de 1930. Foram nos regimes totalitários do Ocidente que se desenvolveram fundamentos de uma propaganda política atual, com mecanismos de persuasão capazes de acionar sentimentos coletivos e universos simbólicos sociais, com estética elaborada pelos agentes conectados a ideologias e partidos políticos da época. O objetivo é apresentar e discutir conexões entre a propaganda política e a publicidade tendo em vista suas influências mútuas, advindas de suas experiências históricas. Trata-se de um estudo exploratório que faz uso de referencial teórico sobre os eixos temáticos da propaganda política e propaganda comercial com ênfase conceitual e histórica. A partir da sistematização do objeto de estudo, o artigo mostra que a intersecção da propaganda política e comercial se evidencia no início do século XX e intensifica suas conexões neste início de século XXI com o uso de recursos estéticos e discursivos mais sofisticados. Parece, portanto, que as experiências da propaganda comercial têm suprido campanhas eleitorais e a comunicação política, proporcionando cenários políticos caracterizados pela persuasão, efemeridade e apego estético nos moldes da concepção publicitária.
