Maximum Number of Minimum Dominating and Minimum Total Dominating Sets

Given a connected graph with domination (or total domination) number \gamma>=2, we ask for the maximum number m_\gamma and m_{\gamma,T} of dominating and total dominating sets of size \gamma. An exact answer is provided for \gamma=2and lower bounds are given for \gamma>=3.Comment: 6 page

Intimacy as a Concept: Explaining Social Change in the Context of Globalisation or Another Form of Ethnocentricism?

This article focuses on intimacy in terms of its analytical potential for understanding social change without the one-nation blinkers sometimes referred to as 'methodological nationalism' and without Euro-North-American ethnocentrism. Extending from the concept of family practices, practices of intimacy are sketched and examples considered across cultures. The cultural celebration and use of the term 'intimacy' is not universal, but practices of intimacy are present in all cultures. The relationship of intimacy to its conceptual relatives is clarified. A brief discussion of subjectivity and social integration restates the relevance of intimate relationships and practices of intimacy to understanding social change in an era of globalisation, despite the theoretical turn away from embodied face to face relationships. Illustrations concerning intimacy and social change in two areas of personal life, parental authority and gender relations, indicate that practices of intimacy can re-inscribe inequalities such as those of age, class and gender as well as subvert them and that attention to practices of intimacy can assist the need to explain continuity as well as change.Love and Intimacy, Globalization, Ethnocentric, Social Change, Inequality, Discourse, Family Practices

Access and Preservation in Archival Mass Digitization Projects

[Excerpt] In 2014, the Dalhousie University Archives began its first archival mass digitization project with the Elisabeth Mann Borgese fonds. The successful completion of this project required the project team to address both broad and specific technical and intellectual challenges, from rights management in an online access environment to the durability of the equipment used. To best understand the challenges faced, there will first be a brief introduction to the fonds and project goals of balancing preservation and access before moving on to a discussion of these challenges in further detail, and finally, concluding with a discussion of some considerations, best practices, and lessons learned from this project

S-wave and p-wave scattering in a cold gas of Na and Rb atoms

Using improved experimentally based $X{}^1\Sigma^+$ and $a{}^3\Sigma^+$ molecular potentials of NaRb, we apply the variable phase method to compute new data for low energy scattering of $^{23}$Na atoms by $^{85}$Rb atoms and $^{87}$Rb atoms. These are the scattering lengths and volumes, numbers of bound states and effective ranges, which we use to obtain the low energy spin-change cross section as functions of the system temperature and the isotope masses. From an analysis of the contributions of s-wave and p-wave scatterings to the elastic cross section we estimate temperatures below which only s-wave scattering is dominant. We compare our quantal results to data obtained from the semiclassical approximation. We supply evidence for the existence of a near zero energy p-wave bound state supported by the singlet molecular potential.Comment: The article contains additional material and data (see abstract

The Future for Architects?

In this study Building Futures sets out to explore the future role of architects, asking: who will design our buildings in 2025; what roles will those trained in architecture be doing then and how will architectural practice have changed as a result? Through a series of one-to-one interviews and round table sessions the study aims to examine the breadth of those who shape the built environment: including traditional architects and those working in expanded fields of practice, as well as clients, consultants and contractors. The resulting speculations should be an opportunity for discussion and interrogation- an exploration of the imminent changes likely to affect the industry over the next 15 years
