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
Contemporary Criminological Issues tackles some of today’s most pressing social issues, from the criminalization of Indigenous peoples to interpersonal violence, border control, and armed conflicts. This book advances cutting-edge theories and methods, with the aim of moving beyond the scholarship that reproduces insecurity and exclusion. The breadth of approaches encompasses much of the current critical criminological scholarship, serving as a counterpoint to the growth of managerial and administrative criminologies and the rise of explicitly exclusionary and punitive state policies and practices with respect to ‘crime’ and ‘security.’ This edited collection featuring two books, one in English and one in French, includes important contributions to knowledge and public policy by eminent experts and emerging scholars. This book is published in English.

Book Description
In the past two or three decades, fractured rock domains have received increasing attention not only in reservoir engineering and hydrology, but also in connection with geological isolation of radioactive waste. Locations in both the saturated and unsaturated zones have been under consideration because such repositories are sources of heat and potential sources of groundwater contamination. Thus, in addition to the transport of mass of fluid phases in single and multiphase flow, the issues of heat transport and mass transport of components have to be addressed.

Book Description
This book introduces a new form of documentary film: the Geo-Doc, designed to maximize the influential power of the documentary film as an agent of social change. By combining the proven methods and approaches as evidenced through historical, theoretical, digital, and ecocritical investigations with the unique affordances of Geographic Information System technology, a dynamic new documentary form emerges, one tested in the field with the United Nations. This book begins with an overview of the history of the documentary film with attention given to how it evolved as an instrument of social change. It examines theories surrounding mobilizing the documentary film as a communication tool between filmmakers and policymakers. Ecocinema and its semiotic storytelling techniques are also explored for their unique approaches in audience engagement. The proven methods identified throughout the book are combined with the spatial and temporal affordances provided by GIS technology to create the Geo-Doc, a new tool for the activist documentarian.

Book Description
Early in the twentieth century, maternal and child welfare evolved from a private family responsibility into a matter of national policy. Molly Ladd-Taylor explores both the private and public aspects of child-rearing, using the relationship between them to cast new light on the histories of motherhood, the welfare state, and women's activism in the United States. Ladd-Taylor argues that mother-work, "women's unpaid work of reproduction and caregiving," motivated women's public activism and "maternalist" ideology. Mothering experiences led women to become active in the development of public health, education, and welfare services. In turn, the advent of these services altered mothering in many ways, including the reduction of the infant mortality rate.

Book Description
Prairie Fairies draws upon a wealth of oral, archival, and cultural histories to recover the experiences of queer urban and rural people in the prairies. Focusing on five major urban centres, Winnipeg, Saskatoon, Regina, Edmonton, and Calgary, Prairie Fairies explores the regional experiences and activism of queer men and women by looking at the community centres, newsletters, magazines, and organizations that they created from 1930 to 1985.? Challenging the preconceived narratives of queer history, Valerie J. Korinek argues that the LGBTTQ community has a long history in the prairie west, and that its history, previously marginalized or omitted, deserves attention. Korinek pays tribute to the prairie activists and actors who were responsible for creating spaces for socializing, politicizing, and organizing this community, both in cities and rural areas. Far from the stereotype of the isolated, insular Canadian prairies of small towns and farming communities populated by faithful farm families, Prairie Fairies historicizes the transformation of prairie cities, and ultimately the region itself, into a predominantly urban and diverse place.
