The identity [r]evolution is happening. Who are you, who am I in the information society? In recent years, the convergence of several factors - technological, political, economic - has accelerated a fundamental change in our networked world. On a technological level, information becomes easier to gather, to store, to exchange and to process. The belief that more information brings more security has been a strong political driver to promote information gathering since September 11. Profiling intends to transform information into knowledge in order to anticipate one's behaviour, or needs, or preferences. It can lead to categorizations according to some specific risk criteria, for example, or to direct and personalized marketing. As a consequence, new forms of identities appear. They are not necessarily related to our names anymore. They are based on information, on traces that we leave when we act or interact, when we go somewhere or just stay in one place, or even sometimes when we make a choice. They are related to the SIM cards of our mobile phones, to our credit card numbers, to the pseudonyms that we use on the Internet, to our email addresses, to the IP addresses of our computers, to our profiles... Like traditional identities, these new forms of identities can allow us to distinguish an individual within a group of people, or describe this person as belonging to a community or a category. How far have we moved through this process? The identity [r]evolution is already becoming part of our daily lives. People are eager to share information with their "friends" in social networks like Facebook, in chat rooms, or in Second Life. Customers take advantage of the numerous bonus cards that are made available. Video surveillance is becoming the rule. In several countries, traditional ID documents are being replaced by biometric passports with RFID technologies. This raises several privacy issues and might actually even result in changing the perception of the concept of privacy itself, in particular by the younger generation. In the information society, our (partial) identities become the illusory masks that we choose -or that we are assigned- to interplay and communicate with each other. Rights, obligations, responsibilities, even reputation are increasingly associated with these masks. On the one hand, these masks become the key to access restricted information and to use services. On the other hand, in case of a fraud or negative reputation, the owner of such a mask can be penalized: doors remain closed, access to services is denied. Hence the current preoccupying growth of impersonation, identity-theft and other identity-related crimes. Where is the path of the identity [r]evolution leading us? The booklet is giving a glance on possible scenarios in the field of identity.

En aquest article es donen a conèixer els resultats més importants de la segona part d'una recerca sobre migració femenina duta a terme durant els anys 2005-2007 a diferents comunitats autònomes espanyoles, finançada per l"Institut de la Dona (Ministeri de Treball i Afers Socials). En aquesta segona fase, l"equip investigador ha tractat de recollir, a partir d"entrevistes, relats de vida i grups de discussió, la valoració personal de les dones migrants àrabs i llatines sobre el seu projecte migratori. Així mateix, aquest estudi els ha permès evidenciar les dificultats que troben aquestes dones en el procés d'acollida en els àmbits laboral, social, educatiu i, fins i tot, familiar, i quins recursos mobilitzen per superar amb èxit aquestes dificultats. Entre alguns d"aquests recursos destaquen les pràctiques cooperatives i les xarxes de solidaritat que estableixen entre elles en els espais de relació formal i informal on participen. I com aquests espais, en la mesura que són sensibles a les necessitats i als interessos de les dones migrants, esdevenen una veritable porta d'entrada a la societat d'acollida.

Using a new dynamical network model of society in which pairwise interactions are weighted according to mutual satisfaction, we show that cooperation is the norm in the hawks-doves game when individuals are allowed to break ties with undesirable neighbors and to make new acquaintances in their extended neighborhood. Moreover, cooperation is robust with respect to rather strong strategy perturbations. We also discuss the empirical structure of the emerging networks, and the reasons that allow cooperators to thrive in the population. Given the metaphorical importance of this game for social interaction, this is an encouraging positive result as standard theory for large mixing populations prescribes that a certain fraction of defectors must always exist at equilibrium.

The number of HIV-infected persons with children and caregiving duties is likely to increase. From this statement, the present study was designed to establish how HIV infected caregivers organise their parenting routines and to determine their support needs. A further aim was to ascertain caregivers' perception of conspicuous behaviours displayed by their children. Finally, it sought to determine the extent to which the caregivers' assessment of their parenting activity is influenced by the required support and their children's perceived conspicuous behaviours. The study design was observational and cross-sectional. Sampling was based on the 7 HIV Outpatient Clinics associated with the national population-based Swiss HIV Cohort Study. It focused on persons living with HIV who are responsible for raising children below the age of 18. A total of 520 caregivers were approached and 261 participated. An anonymous, standardised, self-administered questionnaire was used for data collection. The data were analysed using descriptive statistical procedures and backward elimination multiple regression analysis. The 261 respondents cared for 406 children and adolescents under 18 years of age; the median age was 10 years. The caregivers' material resources were low. 70% had a net family income in a range below the median of Swiss net family income and 30% were dependent on welfare assistance. 73% were undergoing treatment with 86% reporting no physical impairments. The proportion of single caregivers was 34%. 92% of the children were living with their HIV infected caregivers. 80% of the children attended an institution such as a school or kindergarten during the day. 89% of the caregivers had access to social networks providing support. Nevertheless, caregivers required additional support in performing their parenting duties and indicated a need for assistance on the material level, in connection with legal problems and with participation in the labour market. 46% of the caregivers had observed one or more conspicuous behaviours displayed by their children, which indicates a challenging situation. However, most of these caregivers assessed their parenting activity very favourably. Backward elimination multiple regression analysis indicated that a smaller number of support needs, younger age of the eldest child and fewer physical impairments on the part of the caregiver enhance the caregivers' assessment of their parenting activity. Physicians should speak to caregivers living with HIV about their parenting responsibilities and provide the necessary scope for this subject in their consultation sessions. Physicians are in a position to draw their patients' attention to the services available to them.

In my paper I will present some results about ritual kinship and political mobilization of popular groups in an alpine Valley: the Val de Bagnes, in the Swiss canton of Valais. There are two major reasons to choose the Val de Bagnes for our inquiry about social networks: the existence of sharp political and social conflicts during the 18th and the 19th century and the availability of almost systematic genealogical data between 1700 and 1900. The starting point of my research focuses on this question: what role did kinship and ritual kinship play in the political mobilization of popular groups and in the organization of competing factions? This question allows us to shed light on some other uses and meanings of ritual kinship in the local society. Was ritual kinship a significant instrument for economic cooperation? Or was it a channel for patronage or for privileged social contacts? The analysis highlights the importance of kinship and godparentage for the building of homogeneous social and political networks. If we consider transactions between individuals, the analysis of 19th century Val de Bagnes gives the impression of quite open networks. Men and women tried to diversify their relations in order to avoid strong dependency from powerful patrons. Nevertheless, when we consider the family networks, we can notice that most relations took place in a structured social space or a specific "milieu", were intense contacts enhanced trust, although political allegiances and social choices were not fully predictable on the basis of such preferential patterns. In a politically conflictual society, like 19th century Bagnes, ritual kinship interacted with kinship solidarities and ideological factors shaping dense social networks mostly based on a common political orientation. Such milieus sustained the building of political factions, which show surprising stability over time. In this sense, milieus are important factors to understand political and religious polarization in 19th century Switzerland.
