Аннотация В статье рассматривается роль и место Сирии (включая Ливан и Палестину) в системе османских владений на протяжении нескольких веков от османского завоевания до периода правления султана Абдул-Хамида II. В течение четырех столетий османского владычества территория исторической Сирии (Билад аш-Шам) была одним из важнейших компонентов османской системы и играла роль связующего звена между Анатолией, Египтом, Ираком и Хиджазом. Необходимость ежегодной организации хаджа с символами султанской власти и покровительства над святынями Мекки и Медины определяла особую стратегическую важность сирийских провинций Османской империи. Несмотря на ряд серьезных угроз во время общего кризиса османской государственности (конец XVI начало XIX вв.), имперскому центру удалось сохранить контроль над Сирией путем создания сдержек и противовесов между местными элитами. В XIX в. и особенно в период правления Абдул- Хамида II (18761909 гг.), сохранение Сирии под османским контролем стало вопросом существования Османской империи, которая перед лицом растущего европейского давления и интервенции потеряла большую часть своих владений на Балканах и в Северной Африке. Задача укрепления связей между имперским центром и периферией в сирийских вилайетах в последней четверти XIX в. была в целом успешно решена. К началу XX в. Сирия была одним из наиболее политически спокойных и прочно связанных со Стамбулом регионов Османской империи. Этому в значительной степени способствовали довольно высокий уровень общественной безопасности, развитие внешней торговли, рост образования и постепенная интеграция местных элит (как мусульман, так и христиан) в османские государственные и социальные механизмы. Положение Сирии в системе османских владений показало, что процесс ослабления и территориальной дезинтеграции Османской империи в эпоху реформ не был линейным и наряду с потерей владений и влияния на Балканах, в азиатской части империи в течение XIX и начала XX вв. происходил параллельный процесс имперской консолидации.Abstract The article examines the role and place of Greater Syria (including Lebanon and Palestine) in the system of Ottoman possessions over several centuries from the Ottoman conquest to the period of the reign of Abdul Hamid II. For four centuries of Ottoman domination, the territory of historical Syria (Bilad al-Sham) was one of the most important components in the Ottoman system and played the role of a link between Anatolia, Egypt, Iraq and Hijaz. The need to ensure the Hajj with symbols of Sultan power and patronage over the shrines of Mecca and Medina each year determined the special strategic importance of the Syrian provinces of the Ottoman Empire. Despite a number of serious threats during the general crisis of the Ottoman state system (late 16th early 19th centuries), the imperial center managed to maintain control over Syria by creating checks and balances between local elites. In the 19th century. And especially during the reign of Abdul Hamid II (18761909), keeping Syria under Ottoman control became a matter of existence for the Ottoman Empire, which, in the face of increasing European pressure and intervention, lost most of its possessions in the Balkans and North Africa. The task of strengthening ties between the imperial center and the periphery in Syrian vilayets in the last quarter of the 19th century was generally successfully resolved. By the beginning of the 20th century, Syria was one of the most politically calm and firmly connected with Istanbul regions of the Ottoman Empire. This was greatly facilitated by a fairly high level of public safety, the development of foreign trade, the growth of education and the gradual integration of local elites (both Muslims and Christians) into Ottoman state and social mechanisms. Syrias position in the system of Ottoman possessions clearly showed that the process of weakening and territorial disintegration of the Ottoman Empire during the era of reform was not linear, and along with the loss of possessions and influence in the Balkans, in the Asian part of the empire during the 19th and early 20th centuries there was a parallel process of imperial consolidation.

This book examines how the perception of terrorism threat erodes civil liberties, sows doubt about the loyalties of immigrants, and heightens the left-right ideological divide. The book presents original analysis of survey data and experiments conducted in Australia, Europe and the United States.Research in the book posits questions that others have largely avoided: How does the threat of terrorist violence undermine multicultural democracies? What are the psychological and social mechanisms that explain how the threat of terrorism can change political attitudes? What is the relationship between terrorism and death threats? What is the role of media in shaping the perception of terrorism threat? And what are the ethical responsibilities of journalists? This book will help readers distinguish between groundless speculation and solid scientific knowledge of the topic. Moreover, it provides concrete recommendations on how to prevent the most negative consequences of the polarization of political attitudes, such as social divisions, exclusivism and conflict. Given the broad geographical scope of the research presented in the book, specifically North America, Europe and Australia, this book will appeal to broad scope of readers.

Online communities are becoming an important way to support firms towards an open innovation approach. However, knowledge shared in an online community represents only a potential for firm's innovation aims. The effectiveness of exploration and exploitation of this knowledge depends on firm's absorptive capacity. In this work the authors focus on the time an idea, shared within an online community, takes to be transformed from a ‘potential' into a ‘realized' innovation by a firm. In particular, conceiving knowledge as a trajectory across pole of attraction rather than a linear process, the authors develop a model inspired by the solar system metaphor. Preliminary results from a case study are presented. They suggest firms may improve the effectiveness of absorptive capacity exploiting the mediation role of a software tool.

<p>Leadership is an extensively discussed and researched concept in scholarship. A vast amount of literature focuses on adult leadership, especially in a political and organizational context. Adult leadership places emphasis on the role of individual leaders, whilst youth leadership takes a participatory approach. Leadership scholars indicate that this participatory approach to youth leadership, involves young people addressing community concerns and at a civic level, engaging in planning and decision-making. Social participation traits and civic identity are developed during adolescence yet very little research has been undertaken in this area since the 1960s. This suggests that youth leadership is an overlooked research stream. Current studies on Gen Y indicate that this demographic are technologically proficient especially with regard to Web 2.0 tools, but also disengaged from their community. This research project examines the use of online communities to influence the leadership skills of a Gen Y cohort in the context of social participation and civic engagement. In this study a focus group and an online wiki were used to investigate how Gen Y teenagers in Wellington, New Zealand used online communities to develop and exercise their leadership skills through civic and social action endeavours. Results from the study indicate that youth leadership, in an online context, centres on the role of organisers who foster civic participation through online community networks. Thus youth leadership is strengthened through participation in civic and community issues using online communities. Adult perceptions of youth and the low credibility of online communities, as perceived by youth, were found to act as barriers to online youth leadership. The findings highlight the importance of adults acknowledging youth in social participation and civic endeavours. This study extends research in the youth leadership stream and enhances our understanding of Gen Y and their use of online communities.</p>

This chapter focuses on the impact of technology on teacher training through online communities of practice (CoP) and investigates its potential for facilitating continuous professional development for the educators who can create personal learning networks on the web. Wenger's Community of Practice Theory (1998) and Garrison et al.'s (2000) Community of Inquiry (CoI) are explored as underlying theories of CoP. Furthermore, examples of online communities of practice will be briefly enlisted. The chapter will provide brief information how online learning is operationalized within the confines of CoP. The chapter will also discuss role of online communities of practice for teachers' continuous professional development with reference to current literature, explore challenges and focus on suggestions and avenues for further research.

This chapter seeks to impart understanding of the role of employee online communities for enhanced employee engagement and retention in an organization. The highly engaged and motivated employees would contribute more towards accomplishing the organizations goals. The various research studies conducted in the past across the world identify job satisfaction as a major determinant of employee engagement and retention. The role of internal communication through employee online communities of organizations or intranets is theoretically suggested to be a major influencer for the enhancement of employee engagement efforts. This can help to enhance and support culture, corporate values, mission statement, and annual company goals. The purpose of this chapter is to investigate the role that the employee online communities of organizations play in order to support the twin objectives of employee retention and engagement. Engaging employees can be the catalyst for inducing positive change among employees and, as a result, boosting an organization's success.
