L'ETUDE ASYMPTOTIQUE DE L'ANALYSE EN COMPOSANTES PRINCIPALES (A.C.P.) EST REALISEE A L'AIDE DE LA THEORIE DES PERTURBATIONS, SOUS L'HYPOTHESE D'UN ECHANTILLON CONSTITUE DE VARIABLES ALEATOIRES INDEPENDANTES ET IDENTIQUEMENT DISTRIBUEES (I.I.D.). LORSQUE L'OBJECTIF DE L'ETUDE EST DE REPRESENTER LES DISSEMBLANCES ENTRE UNITES STATISTIQUES, IL EST PROPOSE D'UTILISER LE MODELE A EFFETS FIXES, APPELE AUSSI MODELE FONCTIONNEL, POUR LEQUEL LES VARIABLES ALEATOIRES ONT DES ESPERANCES DISTINCTES MAIS SONT I.I.D. APRES CENTRAGE. SOUS LES HYPOTHESES DE CE MODELE LA PROPRIETE SUIVANTE, DE TYPE GAUSS-MARKOV POUR L'A.C.P., EST MONTREE: LE MEILLEUR CHOIX DE METRIQUE EST L'INVERSE DE LA MATRICE DE COVARIANCE DES ERREURS. L'ETUDE ASYMPTOTIQUE DU MODELE A EFFETS FIXES AINSI QUE CELLE D'UN MODELE POUR LEQUEL UN ECHANTILLON "INTERMEDIAIRE" ENTRE L'ECHANTILLON I.I.D. ET L'ECHANTILLON DU MODELE A EFFETS FIXES EST UTILISE, CONDUISENT A LA MEME PROPRIETE. LORSQUE L'OBJECTIF DE L'ETUDE CONCERNE LES RELATIONS ENTRE LES VARIABLES, OUTRE L'A.C.P., D'AUTRES ANALYSES OU MODELES PEUVENT ETRE PROPOSES: LES MODELES STRUCTURELS ET PLUS PARTICULIEREMENT L'ANALYSE EN FACTEURS, LE MODELE DE SELECTION DE COVARIANCE, ... UNE ETUDE BIBLIOGRAPHIQUE SUR LES MODELES FONCTIONNELS ET STRUCTURELS ET UNE ETUDE METHODOLOGIAUE SUR LES DIFFERENTS MODELES ET ANALYSES POUVANT ETRE UTILISES POUR L'ETUDE D'UN TABLEAU (N, P) DE DONNEES, COMPLETENT L'ENSEMBLE DES TRAVAUX

Book Description
A striking account of a colony for the mentally ill that forces a reconsideration of madness in society. What happens when the mentally ill are not isolated from society but are instead welcomed into it and invited to take a place in the fabric of the community? Are fear and rejection replaced by the understanding and sympathy often engendered by familiarity? Or are the barriers between the sane and the mad only strengthened? We have experienced a taste of this scenario in the U.S. in the last decade with the new emphasis on de-institutionalization, but Denise Jodelet takes us to an extraordinary community in France where the mentally ill have assumed a visible and prominent role for more than seventy years. The small French town of Ainay-le-Ch�teau and its environs are the site of a "family colony" for men, established in 1900. Here the patients ("lodgers") live with ordinary families ("foster parents"), hold jobs, and are free to move about the countryside. Jodelet's chronicle of daily life in the colony is made rich and vivid by extensive ethnographic material as she unravels a complex set of relationships, ultimately finding that while some of the barriers between the "other" and the larger society have been overcome, new ones have arisen in their place. This unique social experiment provides invaluable social and cultural insights, illuminating many fundamental issues in psychology, psychiatry, and sociology.

Book Description
This book – the first of a two-volume series – argues that, today, stakeholder thinking has evolved into the study of interactive, mutually engaged and responsive relationships that establish the very context of doing modern business, and create the groundwork for transparency and accountability. This book makes it clear that in today's societies successful companies are those that recognize that they have responsibilities to a range of stakeholders that go beyond mere compliance with the law or meeting the fiduciary responsibility inherent in maximizing returns to shareholders. If in the past the focus was on enhancing shareholder value, now it is on engaging stakeholders for long-term value creation. The process of engagement creates a dynamic context of interaction, mutual respect, dialogue and change – not a one-sided "management" of stakeholders. Indeed, the authors believe the very term "stakeholder management" to be outdated and corporate-centric. Companies can manage their relationships with stakeholders, but frequently cannot actually manage the stakeholders themselves, because, as the activist and collaborative initiatives described in this volume suggest, company-stakeholder relationships are not one-way streets and different institutions bring different agendas, goals and priorities to the engagement. There are clear implications to the way in which stakeholder thinking is unfolding today. If in the past corporate "social" responsibility was simply seen as profitability plus compliance plus philanthropy, now responsible corporate citizenship – or corporate responsibility – means companies being more aware of and understanding the societies in which they operate. Corporate responsibility means recognising that day-to-day operating practices affect stakeholders and that it is in those impacts where responsibility lies, not merely in efforts to "do good". Companies are now faced with a wide array of challenges that mean that senior executives and managers need to be able to deal with issues including greater accountability, human rights abuses, sustainability strategies, corporate governance codes, workplace ethics, stakeholder consultation and management. Stakeholder thinking needs to capture these new realities. The global reach of multinational corporations has served to highlight the need for the (re)integration of business into society, relationships into stakeholder relations, and ethics into managerial practice. The rise in power of global activism involving NGOs, and global business involving multinational corporations, makes it even more critical today for companies to consider the power and interests of corporate stakeholders when developing strategic plans. The interactivity and mutuality of relationships described in this book make it clear that firms and stakeholders share the power and responsibility to influence both the profit potential of the firm and how the benefits of the firm's success impact on society. This important volume brings together leading academic thought on stakeholder thinking for the first time. Unfolding Stakeholder Thinking will be indispensable to corporate managers, NGOs and academics seeking greater understanding of the dynamics of stakeholder thinking in a world of rapidly changing responsibilities.A companion volume, Unfolding Stakeholder Thinking 2, focusing on practical issues such as relationship management, communication, reporting, and performance, is also available.

Book Description
"Your Mindful Compass" takes us behind the emotional curtain to see the mechanisms regulating individuals in social systems. There is great comfort and wisdom in knowing we can increase our awareness to manage the swift and ancient mechanisms of social control. We can gain greater flexibility by seeing how social controls work in systems from ants to humans. To be less controlled by others, we learn how emotional systems influence our relationship-oriented brain. People want to know what goes on in families that give rise to amazing leaders and/or terrorists. For the first time in history we can understand the systems in which we live. The social sciences have been accumulating knowledge since the early fifties as to how we are regulated by others. S. Milgram, S. Ashe, P. Zimbardo and J. Calhoun, detail the vulnerability to being duped and deceived and the difficulty of cooperating when values differ. Murray Bowen, M.D., the first researcher to observe several live-in families, for up to three years, at the National Institute of Mental Health. Describing how family members overly influence one another and distribute stress unevenly, Bowen described both how symptoms and family leaders emerge in highly stressed families. Our brain is not organized to automatically perceive that each family has an emotional system, fine-tuned by evolution and "valuing" its survival as a whole, as much as the survival of any individual. It is easier to see this emotional system function in ants or mice but not in humans. The emotional system is organized to snooker us humans: encouraging us to take sides, run away from others, to pressure others, to get sick, to blame others, and to have great difficulty in seeing our part in problems. It is hard to see that we become anxious, stressed out and even that we are difficult to deal with. But "thinking systems" can open the doors of perception, allowing us to experience the world in a different way. This book offers both coaching ideas and stories from leaders as to strategies to break out from social control by de-triangling, using paradoxes, reversals and other types of interruptions of highly linked emotional processes. Time is needed to think clearly about the automatic nature of the two against one triangle. Time and experience is required as we learn strategies to put two people together and get self outside the control of the system. In addition, it takes time to clarify and define one's principles, to know what "I" will or will not do and to be able to take a stand with others with whom we are very involved. The good news is that systems' thinking is possible for anyone. It is always possible for an individual to understand feelings and to integrate them with their more rational brains. In so doing, an individual increases his or her ability to communicate despite misunderstandings or even rejection from important others. The effort involved in creating your Mindful Compass enables us to perceive the relationship system without experiencing it's threats. The four points on the Mindful Compass are: 1) Action for Self, 2) Resistance to Forward Progress, 3) Knowledge of Social Systems and the 4) The Ability to Stand Alone. Each gives us a view of the process one enters when making an effort to define a self and build an emotional backbone. It is not easy to find our way through the social jungle. The ability to know emotional systems well enough to take a position for self and to become more differentiated is part of the natural way humans cope with pressure. Now people can use available knowledge to build an emotional backbone, by thoughtfully altering their part in the relationship system. No one knows how far one can go by making an effort to be more of a self-defined individual in relationships to others. Through increasing emotional maturity, we can find greater individual freedom at the same time that we increase our ability to cooperate and to be close to others.

Book Description
The volume highlights developments in our understanding of the palaeogeographical, palaeobiological, palaeoclimatic and cryospheric evolution of Antarctica. It focuses on the sedimentary record from the Devonian to the Quaternary Period. It features tectonic evolution and stratigraphy, as well as processes taking place adjacent to, beneath and beyond the ice-sheet margin, including the continental shelf. The contributions in this volume include several invited review papers, as well as original research papers arising from the International Symposium on Antarctic Earth Sciences in Edinburgh, in July 2011. These papers demonstrate a remarkable diversity of Earth science interests in the Antarctic. Following international trends, there is particular emphasis on the Cenozoic Era, reflecting the increasing emphasis on the documentation and understanding of the past record of ice-sheet fluctuations. Furthermore, Antarctic Earth history is providing us with important information about potential future trends, as the impact of global warming is increasingly felt on the continent and its ocean.

Book Description
This title describes the state of the art in all areas of spatial marketing, discussing the various constituents which make up the geography of markets. Demand varies according to location and can be measured according to revenue, the number of households, spending patterns and lifestyles. Supply is also dependent on position, because prices, services, products and available shops rely on location, while the difference between supply and demand is the rationale for the role of the trader. The book also covers the way geographic techniques help to solve marketing problems and contains chapters written by contributors with extensive experience in this field; given that it is crucial for companies to direct their marketing correctly at their target audience, this will be indispensable reading for those involved in this area.
