Simple Combined Model for Nonlinear Excitations in DNA
We propose a new simple model for DNA denaturation bases on the pendulum
model of Englander\cite{A1} and the microscopic model of Peyrard {\it et
al.},\cite{A3} so called "combined model". The main parameters of our model
are: the coupling constant along each strand, the mean stretching
of the hydrogen bonds, the ratio of the damping constant and driven force
. We show that both the length of unpaired bases and the velocity
of kinks depend on not only the coupling constant but also the
temperature . Our results are in good agreement with previous works.Comment: 6 pages, 10 figures, submitted to Phys. Rev.
Human trafficking and organised crime
The Institute of Social Studies is Europe's longest-established centre of higher education and research in development studies. Post-graduate teaching programmes range from six-week diploma courses to the PhD programme. Research at ISS is fundamental in the sense of laying a scientific basis for the formulation of appropriate development policies. The academic work of ISS is disseminated in the form of books, journal articles, teaching texts, monographs and working papers. The Working Paper series provides a forum for work in progress which seeks to elicit comments and generate discussion. The series includes the research of staff, PhD participants and visiting fellows, and outstanding research papers by graduate students. For further information contact
Human Security and the Governmentality of Neo-Liberal Mobility
Transnational migration and its implications for human security as a policy field constitute one of the most complex issues of our time. Current experiences of displacement and security spans between a cyber world characterized by hyper mobility of finance, technology, information and the ‘cosmopolitan’ values of a ‘flexible citizenship’ (Ong, 1999) to the world of human trafficking and smuggling of migrants and refugees as a mode of mobility adopted by people who cross borders on foot, by boat, trucks and planes who are often abandoned to die when arrangements break down (Eschbach/Hagan/Rodriguez, 2001; El-Cherkeh/Hella, 2004). The extant legal vacuum reflects unresolved conflicts of interest at different levels and poses a great challenge to the right to mobility as an expression of the liberal ideal of individual liberty
Development ethics through the lenses of caring, gender, and human security.
Thinking about ethics of development and human development must both treat development
in a global perspective and yet reflect on the content of human. This paper explores some faces
of globalization by using a gender perspective, in order to consider reproduction
(psychological and emotional as well as biological) and the activities and attitudes
of care that give moral resources for response to systemic tragedy,
not only for identifying and understanding it. There now exist globally
interconnected systems of vulnerability and capability, for which matching systems of human security,
care and responsibility are needed in order to protect human dignity. The discourse of human security
helps here by better grounding an agenda of basic human needs, in an ethnography of ordinary lives
rather than only an abstracted accounting of deficiencies or an elevated language of opportunities.
It must be emotionally and existentially grounded too. The authors examine the potential contributions
the tradition of Mahayana Buddhism; the work of philosopher-anthropologist Ananta Giri; and feminist care ethics
Gender, poverty and social justice
Views on poverty are deeply rooted in cultural frameworks about the human condition shaped by histories. In the debate on modernity, perspec
Introductory Remarks
Driven by diverse forces – economic pressures and opportunities, climate change, war, conquest, and transformation of political regimes – human migration has been central to circulation of knowledge and values, goods and labour. Yet, it has been subject to mainly disciplinary inquiries and the existing body of studies has lacked a comprehensive perspective. This volume essays precisely such a more comprehensive historical and experiential perspective, and as a result leads us to reconsider the meanings of ‘human’, ‘movement’, and ‘borders’
