Business and Public–Private Partnerships for Sustainability: Beyond Corporate Social Responsibility?

This article analyses public–private partnerships (PPPs) in the field of sustainable development from an international relations perspective with insights from the business and ethics literature. We argue that the role of business in these types of arrangements has not been sufficiently explored. After presenting three ways of approaching PPPs to stress the many facets of partnerships across the public–private divide, we discuss the emergence of these novel forms of governance from a demand side and contrast such a functionalist reading with the supply side. Then we look at the micro-economic incentives for corporations to engage in such endeavours. We develop arguments derived from the dominant literature to provide an analytical framework for explaining business participation. Finally, we discuss the role of PPPs in light of input and output legitimacy. We conclude by alluding to the emergence of an expectation-capacity gap and normative issues related to the global PPP architecture.

First Annual IMACS Report: A global International Society for Heart and Lung Transplantation Registry for Mechanical Circulatory Support

The first annual report of the International Society for Heart and Lung Transplantation (ISHLT) Mechanically Assisted Circulatory Support (IMACS) registry provides global data on 5,942 patients from 31 countries. This initial report focuses on patient demographics, survival, device types, adverse events, competing outcomes, and a risk factor analysis.

Global lymphoid tissue remodeling during a viral infection is orchestrated by a B cell-lymphotoxin-dependent pathway

Adaptive immune responses are characterized by substantial restructuring of secondary lymphoid organs. The molecular and cellular factors responsible for virus-induced lymphoid remodeling are not well known to date. Here we applied optical projection tomography, a mesoscopic imaging technique, for a global analysis of the entire 3-dimensional structure of mouse peripheral lymph nodes (PLNs), focusing on B-cell areas and high endothelial venule (HEV) networks. Structural homeostasis of PLNs was characterized by a strict correlation between total PLN volume, B-cell volume, B-cell follicle number, and HEV length. After infection with lymphocytic choriomeningitis virus, we observed a substantial, lymphotoxin (LT) beta-receptor-dependent reorganization of the PLN microarchitecture, in which an initial B-cell influx was followed by 3-fold increases in PLN volume and HEV network length on day 8 after infection. Adoptive transfer experiments revealed that virus-induced PLN and HEV network remodeling required LTalpha(1)beta(2)-expressing B cells, whereas the inhibition of vascular endothelial growth factor-A signaling pathways had no significant effect on PLN expansion. In summary, lymphocytic choriomeningitis virus-induced PLN growth depends on a vascular endothelial growth factor-A-independent, LT- and B cell-dependent morphogenic pathway, as revealed by an in-depth mesoscopic analysis of the global PLN structure.

Mountains and Climate Change: A Global Concern

Editor's note: The text of this article originally appeared as the final chapter of a brochure entitled Mountains and Climate Change—From Understanding to Action, prepared at the Centre for Development and Environment, University of Bern, Switzerland, for presentation by the Swiss Agency for Development and Cooperation (SDC) at a side event at the United Nations Climate Change Conference in Copenhagen on 12 December 2009. Chapters of the brochure deal with various aspects of climate change and its impact in mountain regions. In light of the significance of the Copenhagen COP 15 conference, the editors of this publication believe MRD's readers will be interested in reading this summary written from the perspective of Swiss researchers and development experts.
