Putting families of origin into the queer picture : introducing this special issue

In undertaking our own separate research projects and in our crosscontinental comparative analyses of those projects, we became aware of the gaps between the richness of research on GLBT lives, including experiences of intimacy and parenthood, and the paucity of research on their relations with their families of origin. Still marginal is, in particular, research on the perspectives of the families of origin themselves: parents, but also siblings, grandparents, and other members of extended families. For the purposes of this special issue, we are deploying the term families of origin to mean heterosexual-identifying family members (at least as they publicly perform and display their sexualities), living within a heteronormative socio-politicocultural system. As we will argue in this introduction, however, there is a need to document and research, and thereby historically situate, family diversity, including the increasing shifting discourses and lived experiences of same-sex and other queer families of origin.

Guest editors' introduction : Special issue on trust, security, and privacy in parallel and distributed systems

In modern computing paradigms, most computing systems, e.g., cluster computing, grid computing, cloud computing, the Internet, telecommunication networks, Cyber- Physical Systems (CPS), and Machine-to-Machine communication networks (M2M), are parallel and distributed systems. While providing improved expandability, manageability, efficiency, and reliability, parallel and distributed systems increase their security weaknesses to an unprecedented scale. As the system devices are widely connected, their vulnerabilities are shared by the entire system. Because tasks are allocated to, and information is exchanged among the system devices that may belong to different users, trust, security, and privacy issues have yet to be resolved. This special issue of the IEEE Transactions on Parallel and Distributed Systems (TPDS) highlights recent advances in trust, security, and privacy for emerging parallel and distributed systems. This special issue was initiated by Dr. Xu Li, Dr. Patrick McDaniel, Dr. Radha Poovendran, and Dr. Guojun Wang. Due to a large number of submissions, Dr. Zhenfu Cao, Dr. Keqiu Li, and Dr. Yang Xiang were later invited to the editorial team. Dr. Xu Li was responsible for coordinating the paper review process. In response to the call for papers, we received 150 effective submissions, out of which 24 are included in this special issue after rigorous review and careful revision, presenting an acceptance ratio of 16 percent. The accepted papers are divided into three groups, covering issues related to trust, security, and privacy, respectively.
