Human Rights for Health across the United Nations

The United Nations (UN) plays a central role in realizing human rights to advance global health. Looking beyond state obligations, the UN has called on all its specialized agencies to mainstream human rights across all their activities. With globalization compelling these UN institutions to meet an expanding set of global challenges to underlying determinants of health, human rights are guiding these international organizations in addressing public health. These international organizations within the UN system are actively engaged in implementing health-related human rights—in both their mission and their actions to carry out that mission. Through this mainstreaming of human rights, global health institutions have embraced human rights treaty obligations as a framework for global governance. Given the dramatic development of human rights law through the UN and the parallel proliferation of UN institutions devoted to global health and development, there arises an imperative to understand the implementation of human rights in global health governance. This special section analyzes the evolving UN focus on health and human rights in global governance, examining an expansive set of UN institutions that employ human rights in responding to public health challenges in a rapidly globalizing world. To understand the ways in which human rights are implemented, this special section examines the role of institutions across the UN system in the realization of human rights for public health. Drawing from our recent Oxford University Press volume on Human Rights in Global Health: Rights-Based Governance for a Globalizing World, this special section brings together several of the contributors to analyze ongoing efforts to reform UN institutions to mainstream human rights. These contributors—from academia, nongovernmental organizations, and the UN system—explore (1) the foundations of human rights as a framework for global governance, (2) the work of UN organizations across a range of health-related human rights, (3) the influence of rights-based economic governance on public health, and (4) the advancement of health through UN human rights institutions. Looking beyond the chapters in Human Rights in Global Health, this special section examines how international institutions are changing to meet the Sustainable Development Goals (SDGs), with sweeping implications for the mainstreaming of human rights for health across the UN

Naïve Learning in Social Networks: Convergence, Influence and Wisdom of Crowds

We study learning and influence in a setting where agents communicate according to an arbitrary social network and naïvely update their beliefs by repeatedly taking weighted averages of their neighbors’ opinions. A focus is on conditions under which beliefs of all agents in large societies converge to the truth, despite their naïve updating. We show that this happens if and only if the influence of the most influential agent in the society is vanishing as the society grows. Using simple examples, we identify two main obstructions which can prevent this. By ruling out these obstructions, we provide general structural conditions on the social network that are sufficient for convergence to truth. In addition, we show how social influence changes when some agents redistribute their trust, and we provide a complete characterization of the social networks for which there is a convergence of beliefs. Finally, we survey some recent structural results on the speed of convergence and relate these to issues of segregation, polarization and propaganda.Social Networks, Learning, Diffusion, Bounded Rationality

Human Rights in Global Health Governance

Human rights frame global health governance. In codifying a normative foundation for global governance in the aftermath of World War II, states came together under the auspices of an emergent United Nations (UN) to develop human rights under international law. Human rights law, establishing international norms to advance global justice, has thereby become a universally accepted framework for global health, and the past seventy years have witnessed an evolution of international human rights law to define the highest attainable standard of health. Conceptualizing health disparities as rights violations, these health-related human rights offer universal standards to frame government responsibilities for the progressive realization of health and facilitate legal accountability for health policy. Where globalizing forces have created an imperative for global governance institutions to meet an expanding set of global health challenges, human rights have come to guide institutions of global health governance.As rights-based approaches have become fundamental to global health governance, the proliferation of global governance institutions has warranted a wider sharing of human rights responsibilities for health beyond the UN human rights system. Institutions of global governance are not only seen as instrumental to the development of international human rights law but also as essential to assuring the implementation of rights-based obligations in a rapidly globalizing world. Over the past twenty-five years, the UN has sought to formalize these human rights implementation responsibilities across the entire global governance system. Translating international law into organizational action, global governance institutions seek to “mainstream” human rights across their policies, programs, and practices. To understand the ways in which human rights are realized in global health, this Special Issue of Global Health Governance examines the role of global health governance institutions in structuring the implementation of human rights for public health

Band gap engineering in finite elongated graphene nanoribbon heterojunctions: Tight-binding model

A simple model based on the divide and conquer rule and tight-binding (TB) approximation is employed for studying the role of finite size effect on the electronic properties of elongated graphene nanoribbon (GNR) heterojunctions. In our model, the GNR heterojunction is divided into three parts: a left (L) part, middle (M) part, and right (R) part. The left part is a GNR of width $W_{L}$, the middle part is a GNR of width $W_{M}$, and the right part is a GNR of width $W_{R}$. We assume that the left and right parts of the GNR heterojunction interact with the middle part only. Under this approximation, the Hamiltonian of the system can be expressed as a block tridiagonal matrix. The matrix elements of the tridiagonal matrix are computed using real space nearest neighbor orthogonal TB approximation. The electronic structure of the GNR heterojunction is analyzed by computing the density of states. We demonstrate that for heterojunctions for which $W_{L} = W_{R}$, the band gap of the system can be tuned continuously by varying the length of the middle part, thus providing a new approach to band gap engineering in GNRs. Our TB results were compared with calculations employing divide and conquer rule in combination with density functional theory (DFT) and were found to agree nicely.Comment: arXiv admin note: text overlap with arXiv:1404.249
