This book provides readers insights into cyber maneuvering or adaptive and intelligent cyber defense. It describes the required models and security supporting functions that enable the analysis of potential threats, detection of attacks, and implementation of countermeasures while expending attacker resources and preserving user experience. This book not only presents significant education-oriented content, but uses advanced content to reveal a blueprint for helping network security professionals design and implement a secure Software-Defined Infrastructure (SDI) for cloud networking environments. These solutions are a less intrusive alternative to security countermeasures taken at the host level and offer centralized control of the distributed network. The concepts, techniques, and strategies discussed in this book are ideal for students, educators, and security practitioners looking for a clear and concise text to avant-garde cyber security installations or simply to use as a reference. Hand-on labs and lecture slides are located at http://virtualnetworksecurity.thothlab.com/. Features Discusses virtual network security concepts Considers proactive security using moving target defense　 Reviews attack representation models based on attack graphs and attack trees Examines service function chaining in virtual networks with security considerations Recognizes machine learning and AI in network security.

The monograph Actors of Globalization portrays a group of New York businessmen engaged in global trade from 1784 to 1812. It follows their businesses around the world and shows how through wit, flexibility, and the help of a worldwide net of business partners the merchants were able to quickly rise to global entrepreneurs speculating on wars, food crises and slave revolts. The ramifications of their commerce were felt at home, where the merchants invested in land and city development, established new financial institutions and contributed to a rising consumer culture. This book brings together global and local history, arguing that private actors played an important role in the economic and social development of the young United States.

Le concept du Capital Psychologique ou PsyCap est défini comme un état psychologique positif de développement de l’individu. (Luthans, Youssef, & Avolio, 2007). En Belgique, quelques recherches ont été effectuées sur le PsyCap, mais la majorité des études ont été réalisées aux États-Unis. Dans la psychologie organisationnelle, plusieurs recherches ont démontré que le PsyCap est lié aux meilleures performances et à des attitudes positives, telles que la satisfaction au travail, l’engagement organisationnel et à une réduction de l’intention de quitter le travail ou turnover (e.g. Peterson, Luthans, Avolio, Walumbwa & Zhang, 2011).

Dans leur revue de la littérature sur le PsyCap, Newman, Ucbasaran, Zhu et Hirst (2014) suggèrent que le PsyCap peut aider les individus à développer des réseaux avec les collègues au travail (Comportement de Réseau-Networking behavior), ce qui pourrait leur fournir un soutien ainsi que l’accès à l’information et permettre donc le développement des attitudes positives envers l’organisation. Mais ces relations n’ont pas encore été testées. Néanmoins, des études ont démontré qu’avoir des réseaux sociaux solides au niveau intra-organisationnel diminue le turnover parce que les employés qui perçoivent avoir un haut niveau de soutien de la part de leurs collègues éprouvent un sens d’obligation envers eux et sont donc moins susceptibles de vouloir quitter leur travail (e.g Moynihan & Pandey, 2007).

Sur base de la littérature, la première hypothèse de cette étude postule que le Capital Psychologique est relié positivement aux comportements de réseau tandis que la deuxième hypothèse postule un lien significatif entre ce dernier et le niveau de satisfaction, engagement et turnover des employés. Par ailleurs, la troisième, quatrième et cinquième hypothèse postule un effet de médiation de networking behaviour sur la relation entre le PsyCap et la satisfaction au travail, l’engagement et le turnover respectivement. 

L’étude développée démontre que le PsyCap est en effet relié au comportement de réseau (networking) d’une part et d’une autre part, l’étude montre la présence d’un effet médiateur de networking sur la relation entre le PsyCap et l’engagement au travail ainsi que le turnover.

Examples of the value that can be created and captured through crowdsourcing go back to at least 1714 when the UK used crowdsourcing to solve the Longitude Problem, obtaining a solution that would enable the UK to become the dominant maritime force of its time. Today, Wikipedia uses crowds to provide entries for the world's largest and free encyclopedia. Partly fuelled by the value that can be created and captured through crowdsourcing, interest in researching the phenomenon has been remarkable. Despite this - or perhaps because of it - research into crowdsourcing has been conducted in different research silos, within the fields of management (from strategy to finance to operations to information systems), biology, communications, computer science, economics, political science, among others.
