The higher education space: connecting degree programs from individuals’ choices

Abstract

Is it possible to derive organizing principles of higher education systems from the applicants' choices? Here, we introduce the Higher Education Space (HES) as a way to describe the complex relationship between degree programs. The HES is based on the application of methods from network science to data on the revealed preferences of applicants to the higher education systems of Chile and Portugal. Our work reveals: 1) the existence of a positive assortment of featuressuch as gender balance, application scores, unemployment levels, demand-supply ratio, etc -along the network structure of the HES; 2) that the decaying of the prevalence level of a feature from a focal degree program extends beyond the dyadic relationships captured by the HES; 3) temporal variations in different features do not spillover/propagate throughout the system in the same way; 4) differences in unemployment levels reported among pairs of degree programs are minimized when taking into consideration the connectivity structure of the HES, largely outperforming the differences in matched pairs using traditional similarity measures; and 5) grouping of degree programs based in the network structure of the HES provides an applicant perspective that complements existing classification systems. Our findings support the HES as a multi-dimensional framework that can effectively contribute to the governance of higher education systems.

From Co-Location Patterns to an Informal Social Network of Gig Economy Workers

“…To estimate which ties exhibit a positive and statistically significant co-location pattern, we use the φ-correlation method to estimate the strength of the relationship between couriers. We then control for events attributed to pure chance [1,2,17,30]. We define φ ij as the φ-correlation coefficient between a pair of couriers i and j, which can be computed as:…”

Physics problems and instructional strategies for developing social networks in university classrooms

“…A review of network formation in higher education is characterized by students capability to find trustworthy peers (i.e., conformity) who show familiar behaviors and attitudes (i.e., homophily) [10], similar features (e.g., gender, place of birth, scores, etc.) [11], or through hierarchical relationships (i.e., distinction of status) [12]. Each of these micro-mechanisms for tie formation reflects the extent to which individuals project their attributes into the social space, hoping to find others who reflect similarities in the case of conformity and homophily, or different ones in order to select weaker or stronger peers that could enable different opportunities.…”

Reciprocity heightens academic performance in elementary school students

“…In recent decades, several studies emphasize a significant association between students' social relationships and their academic performance at different ages ( Baldwin et al., 1997 ; Caprara et al., 2000 ; Bruun and Brewe, 2013 ; Gašević et al., 2013 ; Blansky et al., 2013 ; Ivaniushina and Alexandrov, 2018 ; Stadtfeld et al., 2019 ; Kassarnig et al., 2018 ; Berthelon et al., 2019 ; Pulgar et al., 2020 ; Candia et al., 2022a , Candia et al., 2022b ; Pulgar et al., 2022a , Pulgar et al., 2022b ; Candia et al., 2019 ; Smirnov and Thurner, 2017 ). For instance, academic performance correlates positively with social capital–the individuals’ network of connections and tacit cooperation ( Halpern, 2005 )–among college students in online degree programs ( Gašević et al., 2013 ), and with the flow of online and offline communication among undergraduates ( Kassarnig et al., 2018 ).…”
