Background. Physical education (PE) aims to enhance self-esteem, develop sporting interests and to encourage a physically active life-style. However, little is known about how a fear of negative evaluation (FNE), the socially evaluative aspect of social anxiety, affects children's attitudes to PE.

Aim. The aim of the study was to investigate the relationships between perceived athletic competence and FNE within PE lessons, specifically looking at differences between boys and girls and primary and secondary schools.

Sample. The participants were 192 children in three primary schools (N=85, mean age=9.5±1.1 years) and two secondary schools (N=107, mean age=14.5±0.8 years) from rural areas of North Wales and the Midlands region of England.

Methods.
The participants completed the Brief-FNE Scale and the Self-Perception Profile for Children immediately post-lesson on one occasion.

Results. Girls had higher FNE but lower perceptions of athletic competence than did boys. Older girls had higher FNE and lower perceived competence than the remaining three groups. Additionally, a significant and reverse but weak correlation was observed between girls' perceived athletic competence and FNE.

Conclusions.
The findings suggest that girls with a high FNE report lower perceptions of their athletic competence. Individuals who are high in FNE behave in ways to avoid the prospect of being evaluated negatively. However, they may seek feedback from significant others as a signal that unfavourable evaluations have been avoided. Therefore, positive, encouraging feedback used in child-centred learning strategies may foster feelings of competence in boys and girls and could reduce the girls' social anxiety.

This study evaluated the effectiveness of a healthy body image program. In total, 421 adolescent boys completed a five-session intervention program or a wait list control group. There were no differences between the intervention and the control group at post-intervention or any of the follow-up times. Boys in the intervention group who were one standard deviation above the mean on body dissatisfaction at baseline, demonstrated a reduction in negative affect in the intervention group at post-test and 6 months follow-up. Prevention programs need to target boys who are at risk of adopting health risk behaviors, rather than being universally applied.

BACKGROUND: Survivin is a member of the inhibitor-of-apoptosis (IAP) family which is widely expressed by many different cancers. Overexpression of survivin is associated with drug resistance in cancer cells, and reduced patient survival after chemotherapy and radiotherapy. Agents that antagonize the function of survivin hold promise for treating many forms of cancer. The purpose of this study was to investigate whether a cell-permeable dominant-negative survivin protein would demonstrate bioactivity against prostate and cervical cancer cells grown in three dimensional culture.

RESULTS: A dominant-negative survivin (C84A) protein fused to the cell penetrating peptide poly-arginine (R9) was expressed in E. coli and purified by affinity chromatography. Western blot analysis revealed that dNSurR9-C84A penetrated into 3D-cultured HeLa and DU145 cancer cells, and a cell viability assay revealed it induced cancer cell death. It increased the activities of caspase-9 and caspase-3, and rendered DU145 cells sensitive to TNF-α via by a mechanism involving activation of caspase-8.

CONCLUSIONS: The results demonstrate that antagonism of survivin function triggers the apoptosis of prostate and cervical cancer cells grown in 3D culture. It renders cancer cells sensitive to the proapoptotic affects of TNF-α, suggesting that survivin blocks the extrinsic pathway of apoptosis. Combination of the biologically active dNSurR9-C84A protein or other survivin antagonists with TNF-α therapy warrants consideration as an approach to cancer therapy.

To investigate the effects of mood on people’s end-of-life treatment decisions and their false memories of those decisions, participants took part in two sessions. At Time 1, participants were experimentally induced into positive or negative moods. They decided whether they would want to receive or refuse treatments in a range of hypothetical medical scenarios, such as tube feeding while in a coma. Four weeks later, at Time 2, participants were induced into the same or the opposite mood and made these decisions a second time. They also recalled their previous decisions. Participants in negative moods at Time 2 changed more of their current decisions and falsely remembered more of their previous decisions than participants in positive moods. These findings suggest that people’s current moods influence whether they change their treatment decisions; current decisions in turn bias recall of past decisions

This article presents a novel approach to data mining that incorporates both positive and negative association rules into the analysis of outbound travelers. Using datasets collected from three large-scale domestic tourism surveys on Hong Kong residents' outbound pleasure travel, different sets of targeted rules were generated to provide promising information that will allow practitioners and policy makers to better understand the important relationship between condition attributes and target attributes. This article will be of interest to readers who want to understand methods for integrating the latest data mining techniques into tourism research. It will also be of use to marketing managers in destinations to better formulate strategies for receiving outbound travelers from Hong Kong, and possibly elsewhere.

The forces of globalisation over the last few decades have created opportunities for intemational business as never before, whilst leaving no organisation immune to competition. With the Global Financial Crisis impacting the world economy, the BRIC economies as a group - Brazil, Russia, India and China, have steadily benefited from continuing growth in 2008 and 2009 (Bhattacharya, Hemerling and Waltermann,2010). Despite China being a key international trading partner for Australia, the number of successful joint ventures and negotiations between the two countries remains limited. A closer examination of the international business interactions between Australia and China is thus urgently needed. When negotiating with the Chinese, Western managers may not always be aware of what they are really negotiating for. To be successful, they have to be equipped with the 'specialised knowledge', a form of 'tacit or implicit knowledge', which comes with experience (Nonaka, 1994, Pavesi, 2003) in communicating and negotiating with their Chinese counterparts. The Chinese way of business negotiation can challenge the logic of Western business thinking. This, coupled with possible generational differences or changes in the Chinese business counterpart's way of doing business, means we must try to understand the business communication and negotiation process from not only the Western but also the Chinese perspective. In particular, in addition to the contextual (Phatak, & Habib, 1996; Risberg, 1997), social (Ghauri, & Fang, 2001), and cognitive factors (George, Gareth, & Gonzalez, 1998) focused on by past researchers, the intangible aspects of negotiation must also be considered. These include trust, reputation, relationship quality (guanxi in the case of the Chinese), and the moods and emotions that shape the processes and outcomes of communication and negotiation (Griffith, 2002; Hartel & Ma, 2006; Ma & Hartel 2005; and Zhao & Krohmer, 2006). This paper reports on a qualitative investigation of the communication processes occurring in negotiations between Australian and Chinese managers and entrepreneurs. The examination is based on a theoretical framework looking at emotions and culture from an affective events theory (AET) perspective. Both interview and focus groups techniques were used. Findings identified guanxi, core to relationship development and maintenance in Chinese culture, together with emotions as major determining factors of negotiation outcomes. Findings also suggest there are generational differences in attitudes among Chinese managers with Gen. X and Gen. Y placing a different emphasis on guanxi in business. These findings suggest that the popular advice to people doing business in China is out of date.
