Synergizing in Cyberinfrastructure Development

This paper investigates the work of creating infrastructure, using as a case study the development of cyberinfrastructure for metagenomics research. Specifically, the analysis focuses on the role of embeddedness in infrastructure development. We expand on the notion of human infrastructure to develop the concepts of synergizing, leveraging, and aligning, which denote the active processes of creating and managing relationships among people, organizations, and technologies in the creation of cyberinfrastructure. This conceptual lens highlights how embeddedness is not only an important result of infrastructure development, but is also a precursor that can act as both a constraint and a resource for development activities.

Collaboration in Metagenomics: Sequence Databases and the Organization of Scientific Work

In this paper we conduct an ethnographic study of work to explore the interaction between scientific collaboration and computing technologies in the emerging science of metagenomics. In particular, we explore how databases serve to organize scientific collaboration. We find databases existing across scientific communities where scientists have different practices and priorities. We suggest while these databases appear to be boundary objects, they are better understood as boundary negotiating artifacts. Due to rapid scientific and technical innovation the tools, practices, and scientific questions change over the course of merely a few years resulting in challenges for collaboration.

Globally distributed system developers: their trust expectations and processes

Trust remains a challenge in globally distributed development teams. In order to investigate how trust plays out in this context, we conducted a qualitative study of 5 multi-national IT organizations. We interviewed 58 individuals across 10 countries and made two principal findings. First, study participants described trust in terms of their expectations of their colleagues. These expectations fell into one of three dimensions: that socially correct behavior will persist, that team members possess technical competency, and that individuals will demonstrate concern for others. Second, our study participants described trust as a dynamic process, with phases including formation, dissolution, adjustment and restoration. We provide new insights into these dimensions and phases of trust within distributed teams which extend existing literature. Our study also provides guidelines on effective practices within distributed teams in addition to providing implications for the extension of software engineering and collaboration tools.

The founding charter of the Genomic Observatories Network

The co-authors of this paper hereby state their intention to work together to launch the Genomic Observatories Network (GOs Network) for which this document will serve as its Founding Charter. We define a Genomic Observatory as an ecosystem and/or site subject to long-term scientific research, including (but not limited to) the sustained study of genomic biodiversity from single-celled microbes to multicellular organisms.An international group of 64 scientists first published the call for a global network of Genomic Observatories in January 2012. The vision for such a network was expanded in a subsequent paper and developed over a series of meetings in Bremen (Germany), Shenzhen (China), Moorea (French Polynesia), Oxford (UK), Pacific Grove (California, USA), Washington (DC, USA), and London (UK). While this community-building process continues, here we express our mutual intent to establish the GOs Network formally, and to describe our shared vision for its future. The views expressed here are ours alone as individual scientists, and do not necessarily represent those of the institutions with which we are affiliated.

The work of developing cyberinfrastructure middleware projects

Middleware software, which provides an abstraction layer between low-level computational services and domain-specific applications, is a key component of cyberinfrastructure. This paper presents a qualitative study of how cyberinfrastructure middleware development is accomplished in two supercomputing centers. Our investigation highlights key development phases in the lives of middleware projects. Middleware development is typically undertaken as part of collaborations between technologists and domain scientists, and middleware developers must balance the pressure to meet specific scientific needs and the desire to explore their own R&D agendas. We explore how developers work to sustain an ongoing development trajectory by aligning their own work with particular domain science projects and funding streams. However, we find that the key transition from being a component in a domain-specific project to a stand-alone system that is useful across domains is particularly challenging for middleware development. We provide organizational and national policy implications for how to better support this transition.

Effects of communication media on the interpretation of critical feedback

This paper presents an experimental study of how interpersonal critical feedback is interpreted and used in electronically mediated communication environments. In a pair of experiments, Writers receive feedback about a document from Critics over instant messaging (IM) or videoconferencing. The results suggest that when Writers cannot see and hear the Critic, they interpret feedback to be more negative and less credible, and are less likely to incorporate suggested changes.

Reimagining Human Research Protections for 21st Century Science.

Background Evolving research practices and new forms of research enabled by technological advances require a redesigned research oversight system that respects and protects human research participants. Objective Our objective was to generate creative ideas for redesigning our current human research oversight system. Methods A total of 11 researchers and institutional review board (IRB) professionals participated in a January 2015 design thinking workshop to develop ideas for redesigning the IRB system. Results Ideas in 5 major domains were generated. The areas of focus were (1) improving the consent form and process, (2) empowering researchers to protect their participants, (3) creating a system to learn from mistakes, (4) improving IRB efficiency, and (5) facilitating review of research that leverages technological advances. Conclusions We describe the impetus for and results of a design thinking workshop to reimagine a human research protections system that is responsive to 21st century science.

Privacy Attitudes among Early Adopters of Emerging Health Technologies.

Introduction Advances in health technology such as genome sequencing and wearable sensors now allow for the collection of highly granular personal health data from individuals. It is unclear how people think about privacy in the context of these emerging health technologies. An open question is whether early adopters of these advances conceptualize privacy in different ways than non-early adopters. Purpose This study sought to understand privacy attitudes of early adopters of emerging health technologies. Methods Transcripts from in-depth, semi-structured interviews with early adopters of genome sequencing and health devices and apps were analyzed with a focus on participant attitudes and perceptions of privacy. Themes were extracted using inductive content analysis. Results Although interviewees were willing to share personal data to support scientific advancements, they still expressed concerns, as well as uncertainty about who has access to their data, and for what purpose. In short, they were not dismissive of privacy risks. Key privacy-related findings are organized into four themes as follows: first, personal data privacy; second, control over personal information; third, concerns about discrimination; and fourth, contributing personal data to science. Conclusion Early adopters of emerging health technologies appear to have more complex and nuanced conceptions of privacy than might be expected based on their adoption of personal health technologies and participation in open science. Early adopters also voiced uncertainty about the privacy implications of their decisions to use new technologies and share their data for research. Though not representative of the general public, studies of early adopters can provide important insights into evolving attitudes toward privacy in the context of emerging health technologies and personal health data research.

A sociotechnical exploration of infrastructural middleware development

While previous CSCW research has noted that computer scientists have their own research interests pertaining to cyberinfrastructure development projects, most have focused on the research imperatives of scientists. This qualitative, interview-based study investigates the perspective of computer scientists developing middleware software for cyberinfrastructures at two supercomputing centers. This paper examines how technologists develop and sustain middleware applications over time by leveraging expertise and partnering with different research domains in order to achieve long-term infrastructural goals.

MyOSD 2014: Evaluating Oceanographic Measurements Contributed by Citizen Scientists in Support of Ocean Sampling Day

The first Ocean Sampling Day (OSD) took place on June 21, 2014. In a coordinated effort, an internationally distributed group of scientists collected samples from marine surface waters in order to study microbial diversity on a single day with global granularity. Concurrently, citizen scientists enriched the OSD initiative through the MyOSD project, providing additional oceanographic measurements crucial to the contextualization of microbial diversity. Clear protocols, a user-friendly smartphone application, and an online web-form guided citizens in accurate data acquisition, promoting quality submissions to the project’s information system. To evaluate the coverage and quality of MyOSD data submissions, we compared the sea surface temperature measurements acquired through OSD, MyOSD, and automatic in situ systems and satellite measurements. Our results show that the quality of citizen-science measurements was comparable to that of scientific measurements. As 79% of MyOSD measurements were conducted in geographic areas not covered by automatic in situ or satellite measurement, citizen scientists contributed significantly to worldwide oceanographic data gathering. Furthermore, survey results indicate that participation in MyOSD made citizens feel more engaged in ocean issues and may have increased their environmental awareness and ocean literacy.
