The critical path method/program evaluation and review technique method of project scheduling is based on the importance of managing a project's critical path(s). Although a critical path is the longest path through a network, its location in large projects is facilitated by the computation of activity slack. However, logical fallacies in…

This article introduces a methodological approach for articulating and communicating the impact and value of research: qualitative network analysis using collaborative configuration tracing and visualization. The approach was proposed initially in Oancea ("Interpretations and Practices of Research Impact across the Range of Disciplines…

This article presents a case study of a scientist-practitioner research network established by the National Cancer Institute's State and Community Tobacco Control Research Initiative. While prior programs have focused on collaboration among scientists, a goal here was to encourage collaborations with non-university, practice-based partners. Two…

In this study, the associations between peer effects and academic functioning in middle adolescence (N = 342; 14-15 years old; 48% male) were investigated longitudinally. Similarity in achievement (grade point averages) and unexplained absences (truancy) was explained by both peer selection and peer influence, net of acceptance, and connectedness.…

Network analytic methods that are ubiquitous in other areas, such as systems neuroscience, have recently been used to test network theories in psychology, including intelligence research. The network or mutualism theory of intelligence proposes that the statistical associations among cognitive abilities (e.g., specific abilities such as vocabulary…

In this study, we aim to deepen understanding of what it would take to develop the relationships, common understandings, and collective expertise that might support district-wide improvement efforts by examining the implementation of the Common Core and a teacher evaluation policy. Drawing on three years of social network data in three districts,…

Research from outside the medical field suggests that social ties between team-members influence knowledge sharing, improve coordination, and facilitate task completion. However, the relative importance of social ties among team-members for patient satisfaction remains unknown. In this study, we explored the association between social ties within…

The choice of a social network analysis approach for the exploration of relationships in educational settings provides the opportunity for a unique perspective about informal networks of relationships. Rather than considering only the attributes of individuals or organizations, social network analysis affords the opportunity to also examine the…

Rapid adoption of the Common Core State Standards (CCSS), the Race to the Top (RTTT) competition, and backlash around these policies created widespread uncertainty among state educational agencies (SEAs). SEAs may have not had a clear direction about how to support standards implementation in a new context, and therefore, may have looked to their…

Researchers have demonstrated how venture philanthropic networks advance the growth of charter schools underpinned by market tenets. However, little remains known about how progressive charter schools mobilize financial support when most funding from philanthropic networks flows to market-oriented charters. This qualitative study examines how…

The present study examined differential social experiences of international students living in a residential hall called 'Nihongo House' (Japanese language house) at a Japanese university. By conducting social network analysis (SNA), as well as making use of ethnographic data collected through participant observation and semi-structured…

Gender differences in participation were examined across four Twitter chats for social studies teachers. Analyses drawing on mixed methods revealed that while there was parity across most kinds of tweets, participants identified as men were more likely to use the examined Twitter chats to share resources, give advice, boast, promote their own…

Background: Little research exists comparing the social networks of people with intellectual disability (ID) from South Asian and White backgrounds. This UK study reports on the barriers that South Asian people with intellectual disability face in relation to social inclusion compared to their White counterparts. Materials and methods: A…

Our educational systems must prepare students for an increasingly complex and interconnected future, but teachers facing this task are not equipped to prepare students to succeed. Network science--the study of how biological, social, physical and technological systems interconnect, how the structure of those connections evolve over time, and how…

The author's goals in this exercise were to use an Excel project to teach students about the effects of changing states of nature on critical path emergence as well as compare the impact of the PERT beta and triangular distributions on project completion times. Previous research into the PERT (program evaluation and review technique) beta…
