Title: Web and society: a first look into the network of human service providers
Human service organizations (HSOs) operate in an environment considered to be prohibitive of collaboration. To understand how HSOs come together to address the grand challenges associated with meeting human needs, we attempted to automatically construct the network of HSOs based on the information publicly available through each organization's website-the medium that people use to find relevant information to access services. Our analysis of the the complex system of relationships among HSOs in Albany, New York suggests that the network of HSOs in this area exhibits a multipolar structure with few super connectors, and strong relations between organizations that serve similar functions. We quantitatively evaluate the quality of the constructed HSOs' network from Web data based on structured, in-person interviews we conducted with HSOs.  more » « less

    This article examines service coordination patterns across various service areas in Albany, the capital city of the New York State. Based on 42 in-person interviews with executive directors at various human service agencies, inter-organizational network was constructed and analyzed. The network displayed sparse and multipolar connectivity, suggesting that organizations operate in silos, with few organizations holding key positions of structural importance in the network architecture (so-called “super-connectors”). In addition, content analysis drew qualitative insights into perceived challenges to coordinate services. Several factors, both external (e.g., lack of trust or centralized communication system) and internal (e.g., lack of resources or knowledge) might have contributed to the observed structural properties. This finding suggests further examining the role of super-connectors in future research to better understand why these hubs exist and how they can work with other organizations in a cooperative and mutually beneficial manner.

    Abstract Decentralized coordination is one of the fundamental challenges for societies and organizations. While extensively explored from a variety of perspectives, one issue that has received limited attention is human coordination in the presence of adversarial agents. We study this problem by situating human subjects as nodes on a network, and endowing each with a role, either regular (with the goal of achieving consensus among all regular players), or adversarial (aiming to prevent consensus among regular players). We show that adversarial nodes are, indeed, quite successful in preventing consensus. However, we demonstrate that having the ability to communicate among network neighbors can considerably improve coordination success, as well as resilience to adversarial nodes. Our analysis of communication suggests that adversarial nodes attempt to exploit this capability for their ends, but do so in a somewhat limited way, perhaps to prevent regular nodes from recognizing their intent. In addition, we show that the presence of trusted nodes generally has limited value, but does help when many adversarial nodes are present, and players can communicate. Finally, we use experimental data to develop computational models of human behavior and explore additional parametric variations: features of network topologies and densities, and placement, all using the resulting data-driven agent-based (DDAB) model.

    Abstract Motivation Leveraging cross-species information in protein function prediction can add significant power to network-based protein function prediction methods, because so much functional information is conserved across at least close scales of evolution. We introduce MUNDO, a new cross-species co-embedding method that combines a single-network embedding method with a co-embedding method to predict functional annotations in a target species, leveraging also functional annotations in a model species network. Results Across a wide range of parameter choices, MUNDO performs best at predicting annotations in the mouse network, when trained on mouse and human protein–protein interaction (PPI) networks, in the human network, when trained on human and mouse PPIs, and in Baker’s yeast, when trained on Fission and Baker’s yeast, as compared to competitor methods. MUNDO also outperforms all the cross-species methods when predicting in Fission yeast when trained on Fission and Baker’s yeast; however, in this single case, discarding the information from the other species and using annotations from the Fission yeast network alone usually performs best. Availability and implementation All code is available and can be accessed here: github.com/v0rtex20k/MUNDO. Supplementary information Supplementary data are available at Bioinformatics Advances online. Additional experimental results are on our github site.

    CollabNext is being developed as part of the NSF ProtoOKN (Prototype Open Knowledge Network) effort. This project originated as a partnership between Georgia Tech and the Atlanta University Center, and is now being developed jointly by Fisk University, Georgia Tech, Morehouse College, Texas Southern University, and University at Buffalo with support from the NSF TIP Directorate. Our goal is to develop a knowledge graph based on people, organizations, and research topics. We are adopting an intentional design approach which initially prioritizes HBCUs and emerging researchers in a deliberate effort to counterbalance the Matthew effect, a naturally accumulated advantage of well-resourced research organizations. By bringing greater visibility to what and who is often rendered invisible in the current science system, CollabNext will facilitate research collaborations with HBCUs and other MSIs, and illuminate the broader research landscape. Our goal is to utilize open science data sources, follow human-centered design principles, and leverage state-of-the-art algorithms to build a platform that will help identify existing and cultivate new research partnerships that include emerging research institutions.

    Under NASA’s Artemis program, NASA is planning to send astronauts back to the Moon in the next couple of years. Near term missions will be analogous but much more sophisticated versions of the last couple of Apollo missions. However, unlike Apollo, this time NASA intends to put the infrastructure in place to support long term human presence and eventual industrialization of the Moon. To make this vision a reality, NASA plans to collaborate with commercial and international partners as much as possible as opposed to developing, building, and operating equipment on its own. Lunar infrastructure will eventually be built over time by many organizations, public and private, to support sustained human exploration, science, and industrial activities. Obviously, this vision for the future will be impossible without a robust lunar communications and navigation system that can support many users with varying degrees of services. On Earth, most people are very familiar with the 3rd Generation Partnership Project (3GPP) 5G mobile telecommunications technology. NASA’s Space Technology Mission Directorate and NASA’s Space Communications and Navigation office would like to see a lunar communications and navigation network with similar capabilities to the cellular communication networks most of us enjoy today. Building such a network will require participation by many organizations. This paper will provide an overview of NASA’s interest in using 5G and beyond on the lunar surface; it will also describe current work based on 3GPP standards within NASA or funded by NASA, such as Nokia’s upcoming Tipping Point demonstration of 4G / LTE on the lunar surface.
