Despite a resurgence of research on negative ties in social networks, a comprehensive understanding of negative and positive has yet to be provided. Incorporating evidence from prior 163 independent samples we examine whether the initiation of positive and negative relationships (i.e., out-degree) or the reception of positive and negative relationships (i.e., in-degree) is more impactful to the focal employee’s effectiveness. Furthermore, to address the negative asymmetry hypothesis in social networks, we compare the relative importance of positive versus negative work relationships while holding the directionality constant. This meta-analytic review makes five contributions to theory on negative and positive social networks by (a) demonstrating the undermining impact of negative ties on performance and job attitudes; (b) providing information on the negative asymmetry hypothesis within social networks to reveal that negative ties occur less frequently than positive ties and that any asymmetry effects depend on the relative number of negative ties to positive ties in the context; (d) distinguishing between haters (senders of negative ties) and jerks (receivers of negative ties) to illustrate that haters have worse job attitudes than jerks, but the two do not differ on performance; and (e) providing positive and negative affect as antecedents to negative ties. Implications of these findings along with study limitations and future research directions are discussed.​

Are we really going to Mars? The astronautical community certainly believes the answer is “yes.” Scientists all over the world are solving puzzles related to rocket reusability, human resistance to radiation exposure, and terraforming Mars to warm it up and give it a breathable atmosphere. The scientific challenges of a Mars mission are not confined to physical science and engineering. Once the rockets are built and tested, we will ultimately be sending human teams off to explore the galaxy. A central mission parameter for deep space exploration is teamwork. Communication Studies Professors Leslie DeChurch and Noshir Contractor are working with NASA to assemble and support inter-planetary dream teams. In this session, we will share the current plans for space travel and colonization, provide a behind the scenes look at how we are designing teams, and help you design dream teams back on Earth.

SONIC members present various projects throughout SIOP 2018:

Noshir Contractor presented on “Leveraging Computational Social Science to Address Grand Societal Challenges” on April 16, 2018.

The increased access to big data about social phenomena in general, and network data in particular, has been a windfall for social scientists. But these exciting opportunities must be accompanied with careful reflection on how big data can motivate new theories and methods. Using examples of his research in areas of disaster response, global health, scientific collaboration, and the mission to Mars, Contractor will argue that computational social science serves as the foundation to unleash the intellectual insights locked in big data. More importantly, he will illustrate how these insights offer social scientists in general, and social network scholars in particular, an unprecedented opportunity to engage more actively in monitoring, anticipating, and designing interventions to address grand societal challenges.

The Ph.D. student, Diego Gómez-Zará, and the CITEP’s Director of Projects, Silvia Andreoli, presented the findings and results of the My Dream Team case study elaborated at the Universidad de Buenos Aires, Argentina. Both scholars were interviewed in the program “Académicamente” transmitted by the radio of the university. The objective of this program is to generate a space for sharing and diffusing research projects of the university. The interview was on April 10th.
