Magnesium and its alloys have shown a great potential in effective hydrogen storage due to their advantages of high volumetric/ gravimetric hydrogen storage capacity and low cost. However, the use of these materials in fuel cells for automotive applications at the present time is limited by high hydrogenation temperature and sluggish sorption kinetics. This paper presents the recent results of design and development of magnesium-based nanocomposites demonstrating the catalytic effects of carbon nanotubes and transition metals on hydrogen adsorption in these materials. The results are promising for the application of magnesium materials for hydrogen storage, with significantly reduced absorption temperatures and enhanced ab/desorption kinetics. High level Density Functional Theory calculations support the analysis of the hydrogenation mechanisms by revealing the detailed atomic and molecular interactions that underpin the catalytic roles of incorporated carbon and titanium, providing clear guidance for further design and development of such materials with better hydrogen storage properties.

This study examines the cultural value orientations (VOs) of employees (managerial and non-managerial) working in three categories of organizations (professional, technical and local services) in India, Poland, Russia and the USA. The analysis is conducted at both the national and organizational levels. The paper hypothesizes cultural differences at the country level and cultural similarities among employees working for professional and technical oriented organizations and divergence in the VOs of employees working for local services organizations. It also hypothesizes differences in the VOs of managerial and non-managerial employees in the four countries. The investigation has been conducted with the help of a questionnaire survey of 1,852 respondents. The outcomes of the analysis show that there are both cross-country cultural differences and similarities among the VOs of employees of the four nations. Further, significant cultural convergence emerges in the VOs of employees working for both professional and technical organizations, however, no significant cultural similarities or differences are observed for employees of service-based organizations in the four countries. There are some similarities emerging between managerial employees in the research countries. The research contributes to the fields of cross-cultural management, international management and international human resource management.

Three years of action research into a study skills and transition programme for psychology undergraduates are reported. The programme began as a ‘bolt-on’ response to perceptions of student deficit and developed to focus on transition to university. Data from three cohorts and over 600 students show attendance to be associated with higher academic grades and progression rates. The programme has also helped to establish relationships with peers and staff, prepare students for assessments, set expectations about study, and provided an opportunity to ask questions, to work collaboratively and to learn about referencing and plagiarism. Concerns with study skills highlighted by Wingate (2006) and others are discussed.

Despite widespread persecution, Orthodox churches not only survived the Cold War period but levels of religiosity in Orthodox countries remained significant. This book examines the often surprising relations between Orthodox churches and political regimes. It provides a comprehensive overview of the dynamics between Eastern Christianity and politics from the end of the Second World War to the fall of communism, covering 40 Orthodox churches including diasporic churches in Africa, Asia, America and Australia. Based on research from recently-opened archives and publications in a wide range of European languages, it analyses church-state relations on both sides of the Iron Curtain. It discusses the following key themes: the relationship between Orthodox churches and political power; religious resistance to communism; the political control of churches; religion and propaganda; monasticism and theological publications; religious diplomacy within the Orthodox commonwealth; and religious contacts between East and West.

This chapter aims to expand the existing CSD literature by providing insights from current Russian CSD practice, which is believed to be an under researched area. The main objective here is to examine the extent of CSD in Russia. For this purpose content analysis of 2004 annual reports of 20 large companies which are listed on the Russian stock exchange was undertaken. The key findings show that 18 (90%) out of the 20 companies included in the study made some social and environmental disclosures. Employee related disclosures are the dominant category with 90% of companies making some form of disclosures in this category. In addition, 85% of companies made some form of environmental disclosures while only 55% of companies made ethical disclosures. According to this study, the quality of disclosure is generally poor due to lack of external verification and lack of completeness. Although it is more likely that in the future, pressures will be brought to bear on Russian companies to engage in more transparent and accountable CSD practice, still very little optimism for improvement can be expressed here. This is mainly due to lack of mandatory requirements for CSD in Russia and also to some extent due to the absence of strong NGOs and other pressure groups who can exert effective pressures on Russian companies to improve their CSD practice. © 2009 Springer Berlin Heidelberg.

Quercetin is a naturally occurring polyphenol compound present in grapes, red wine, tea, apples and some vegetables. Like other flavonoids, it has been found to have antioxidant activity in studies in vitro, although there is still much debate about the bioavailability of flavonoids in the diet and their in vivo antioxidant activity. In general, it is thought that the antioxidant efficiency of polyphenols increases with increasing hydroxylation of the rings, but there have been few studies of other substitutions. We have prepared several derivatives of quercetin, to test the effect of modification on their antioxidant potential. Sodium salts of quercetin-5-sulfonate and quercetin-5,8-sulfonate, and transition metal complexes of quercetin-5-sulfonate were analysed for their total antioxidant potential using the FRAP assay, and compared to unmodified quercetin. It was found that quercetin-5-sulfonate complexes with Zn, Cu(II), Fe(II) and Mg were all significantly better antioxidants than quercetin, quercetin-5-sulfonate was comparable to quercetin, whereas the sodium salt of quercetin-5,8-sulfonate had a decreased total antioxidant potential. Kinetic studies of the FRAP reaction showed no significant differences between quercitin and any of the derivatives. The reaction of all the quercetins in the FRAP assay was found to be slower to reach completion than ascorbate, and appeared to have biphasic characteristics. These results suggest that transition metal ions may facilitate the transfer of electrons from the polyphenol ring system to the oxidant, while substitution with S03 is electron-withdrawing and destabilizes the ring system. This is important both for understanding the antioxidant ability of flavonoids, and for the design of novel antioxidant compounds. Further work is being carried out to assess the ability of the quercetin complexes to protect cultured cells from oxidative stress.

Focusing on former-Soviet Greeks' experiences of cross-border movement to Greece, this paper sheds light on the impact of this migration on the social identities of Russian Greeks as a transnational community. It draws on informants’ narratives and ethnographic observations recorded among Greek migrants in their home communities in southern Russia, and shows how their motivation, in their transnational movement, is determined by the ‘push-and-pull’ forces of socio-economic and political transformations in post-Soviet space. In these conditions, Greek identity becomes a resource which facilitates the organisation of transnational migration. The cultural, social and economic differences between the former-Soviet Greek migrants and the native-born population of Greece result in the emergence of a Pontic-Greek cultural identity which emphasises migrants’ connections with the former USSR. The difficulties of economic and cultural adaptation for migrants to Greece are examined in relation to the Russian Greeks' economic strategies within their home communities and their perception of the ‘homeland’ as a constantly contested and relocated social construct.
