Summary: The study investigates the evolution of cooperation in the Volunteer's Dilemma using the stochastic Moran process on dynamic graphs, which models a birth-death dynamic on structured finite populations. The results suggest that a high degree of homophily is required for the evolution of cooperation in the Volunteer's Dilemma, while other parameters have relatively small effects on the fixation of cooperation in the population.

Summary: Longitudinal multivariate social network analysis of 3692 adolescents in 136 classrooms revealed that adolescents perceive their friends as popular but do not choose popular peers as friends. Adolescents align their perceptions of popularity with their friends. Those who receive many popularity nominations gain more popularity but not more friendship. Friends of peers seen as popular are more likely to be seen as popular.

Summary: This paper discusses the dynamics of co-offending and its relationship with crime categories. The research findings show that compared to solo offenders, groups of co-offenders are more likely to engage in crime events involving multiple crime categories. Additionally, there is evidence of differential association and social learning in market and property crime within the context of co-offending.

Summary: This paper presents the outcomes of a microcontextual geoarchaeological study conducted on earthen dwellings from the Early Iron Age village of Cerro de San Vicente. The study employed soil micromorphology, lipid biomarker analysis, XRD, and XRF analyses to investigate various aspects of the dwellings, including construction materials, site formation processes, and daily life practices. The results have shed light on the construction layers, floor use, maintenance, repaving, periods of abandonment and decay, and the presence of lipid biomarkers associated with dwelling functionality. The study significantly contributes to our understanding of ancient construction practices and the utilization of domestic spaces during the Early Iron Age.

Summary: This paper discusses alternative estimation methods for approximating maximum likelihood estimates (MLEs), specifically focusing on the maximum pseudo-likelihood estimator (MPLE) as a starting point. The authors exploit the fact that the MPLE fails to satisfy the likelihood principle, leading to different MPLEs for different networks with the same sufficient statistics. The proposed method has shown its merit in producing an MLE for network datasets and models that were difficult to estimate using other known methods.

Summary: This study represents the first application of Organic Residue Analysis (ORA) to southern African early farming pottery to gain a deeper understanding of past human behavior and subsistence patterns. The study found evidence of dairy processing and multi-purpose functionality of the ceramics. It also discovered potential medicinal use and the involvement of dung in pottery sealing and mending.

Summary: People are more likely to interact with others who are similar to them in terms of socio-demographics and values. The loss of ties with dissimilar individuals may contribute to network homogeneity. However, there is limited research on the relationship between similarity and tie loss. This study addresses this gap by investigating the core discussion network of Dutch citizens and examining how ties are embedded in the network.

Summary: The study aims to extend previous research on advice-seeking across organizational boundaries through an agent-based model. By utilizing more realistic assumptions and fitting the simulated network to existing data, the findings demonstrate the advantage of exploring multiple generative paths in analyzing network formation.

Summary: The Exponential Random Graph family of models (ERGM) is a powerful tool for simultaneous modeling of endogenous network characteristics and exogenous variables. This paper examines two methods for estimating multiple networks, hierarchical and integrated, and evaluates their accuracy and advantages. Recommendations are provided for future researchers on how to proceed with multiple network analysis. This research highlights the importance of analyzing multiple networks to gain a comprehensive understanding of social phenomena.

Summary: Chemical treatment of skeletal remains can reduce overall DNA quality and quantity but has no significant impact on stable isotope ratio analysis. Examination of treated and untreated human remains through histological and stable isotope analysis reveals that treated remains exhibit better preservation compared to untreated remains. Stable isotope ratio analysis is viable for both treated and untreated remains, regardless of their origin.

Summary: Venture capital is a rapidly growing industry in China, but it still faces uncertainties. This paper highlights the importance of building a strong social network among VC institutions to mitigate risks and improve financial performance. By analyzing temporal syndication networks based on VC investment records, the study shows that higher networked VC institutions tend to have better financial performance. The use of k-shell decomposition as an evaluation measure reveals distinct groups of VC institutions in China with different financial performance and investment behaviors.

Summary: Previous studies have shown that difficult individuals are present in personal networks and have an impact on them, but little is known about the turnover, retention, and quality change of such difficult ties. This study addresses this gap by examining two forms of network change and identifying associated factors. The findings reveal that over time, some difficult ties reappear as sources of aggravation, some are removed from the network, and others can no longer be verified as problematic members. Exchanging support and kinship play significant roles in these processes, along with personal characteristics such as gender, income, and relocation.

Summary: This study explores the impact of supervisor-employee political relationship and workplace network on dismissal decisions. The findings suggest that the political concerns of supervisors, along with their network circumstances, influence whether an employee is terminated. The study contributes to understanding involuntary turnover beyond performance considerations by highlighting the role of social networks and organizational politics.

Summary: This paper discusses the gender disparities in the screen sector based on a network-based investigation using Australian film and television production data. The analysis reveals that projects led by male directors tend to exclude women and reproduce familiar teams, while projects led by women in key creative roles provide more opportunities for women. Furthermore, the study finds that there is a significant number of men who only work with other men, but no corresponding group of women who only work with women. These findings highlight the importance of equity interventions, particularly government policies, to address the inequalities in the screen industry, which are primarily driven by men's closed network behaviors rather than women's positioning or behavior.

Summary: This study explores the impact of adolescent social network positions on memory performance in adulthood and finds that sociality, degree centrality, and closeness centrality are positively associated with memory performance, while popularity is not. The study also reveals gender differences, with the associations between social network position and memory performance being more pronounced among men. These findings highlight the importance of adolescent social network positions as social determinants in shaping cognitive outcomes.

Summary: In recent decades, the application of aDNA and strontium isotope analyses on archaeologically recovered human remains has provided new insights into the mobility of past societies. This study investigates the mobility, residence, and kinship patterns in late Prehistoric Iberia through the analysis of strontium data on 44 individuals from the site of Humanejos. The findings reveal that 7 out of 44 individuals buried at Humanejos were non-locals, but no statistically significant differences were found in terms of sex or time period. The discovery of a non-local female with exceptional Beaker grave goods raises questions about the relationship between gender, mobility, and social status in this region and time period.
