Beyond the Core
The sociological literature on social networks overwhelmingly considers the number of core social contacts. Social networks, however, reach far beyond this small number of social ties. We know little about individual variation in the size of such extended social networks. In this study, we move beyond core networks and explain individual variation in the extended social network size among youth. We use survey data of Dutch adolescents (N = 5,921) and use two state-of-the-art measurements to compute extended network sizes: network scale-up methods through Bayesian modeling and the observed number of contacts on Facebook. Among both measurements, we find that extended networks are larger among ethnic majority members, girls, and those who often engage in social foci. This highlights a crucial role for preferences and opportunity in the genesis of extended networks. Additionally, we find that differences between both network sizes (scale-up and Facebook) are smaller for girls and higher educated. We discuss the implications of these findings and suggest directions for future research.

Rationality and the reflective mind
\"In this book, Keith Stanovich attempts to resolve the Great Rationality Debate in cognitive science-the debate about how much irrationality to ascribe to human cognition. Stanovich shows how the insights of dual-process theory and evolutionary psychology can be combined to explain why humans are sometimes irrational even though they possess cognitive machinery of remarkable adaptiveness. Using a unique individual differences approach, Stanovich shows that to fully characterize differences in rational thinking, the traditional System 2 of dual-process theory must be partitioned into the reflective mind and the algorithmic mind. He posits that we need to supersede dual-process theories with tripartite models of cognition. The key operations of the algorithmic mind and the reflective mind that support human rationality are discussed in the book. The key function of the algorithmic mind is to sustain the processing of decoupled secondary representations in cognitive simulation. The key function of the reflective mind, in contrast, is to detect the need to interrupt autonomous processing and to begin simulation activities. Stanovich uses the algorithmic/reflective distinction to develop a taxonomy of cognitive errors that are made on tasks in the heuristics and biases literature. He presents empirical data to show that the tendency to make these thinking errors is only modestly related to intelligence. Using the new tripartite model of mind, Stanovich shows how rationality is a more encompassing construct than intelligence-when both are properly defined-and that IQ tests fail to assess individual differences in rational thought. Stanovich discusses the types of thinking processes that would be measured in an assessment of rational thinking\"--Provided by publisher.

Individual variations in cardiovascular-disease-related protein levels are driven by genetics and gut microbiome
Despite a growing body of evidence, the role of the gut microbiome in cardiovascular diseases is still unclear. Here, we present a systems-genome-wide and metagenome-wide association study on plasma concentrations of 92 cardiovascular-disease-related proteins in the population cohort LifeLines-DEEP. We identified genetic components for 73 proteins and microbial associations for 41 proteins, of which 31 were associated to both. The genetic and microbial factors identified mostly exert additive effects and collectively explain up to 76.6% of inter-individual variation (17.5% on average). Genetics contribute most to concentrations of immune-related proteins, while the gut microbiome contributes most to proteins involved in metabolism and intestinal health. We found several host–microbe interactions that impact proteins involved in epithelial function, lipid metabolism, and central nervous system function. This study provides important evidence for a joint genetic and microbial effect in cardiovascular disease and provides directions for future applications in personalized medicine.

Individual differences in trait creativity moderate the state-level mood-creativity relationship
The relationship between mood states and state creativity has long been investigated. Exploring individual differences may provide additional important information to further our understanding of the complex mood-creativity relationship. The present study explored the state-level mood-creativity relationship from the perspective of trait creativity. We employed the experience sampling method (ESM) in a cohort of 56 college students over five consecutive days. The participants reported their state creativity on originality and usefulness dimensions at six random points between 9:00 a.m. and 11:00 p.m., along with a 10-item concurrent mood state report. Their trait creativity was measured by the Guildford Alternative Uses Test (AUT) and the Remote Associates Test (RAT). We found moderating effects of the participants' trait creativity on their state-level mood-creativity relationship. Specifically, whereas the positive correlation between positive mood state and originality of state creativity was stronger for the participants with higher AUT flexibility scores, stronger positive correlations between negative mood state and originality of state creativity were observed for individuals with higher AUT originality scores. Our findings provide evidence in support of introducing individual differences to achieve a more comprehensive understanding of the mood-creativity link. The results could be of practical value, in developing individualized mood state regulation strategies for promoting state creativity.

I never thought of it that way : how to have fearlessly curious conversations in dangerously divided times
Partisanship is up, trust is down, and our social media feeds make us sure we're right and everyone else is ignorant (or worse). But avoiding one another is hurting our relationships and our society. Journalist Mónica Guzmán is the loving liberal daughter of Mexican immigrants who voted--twice--for Donald Trump. When the country could no longer see straight across the political divide, Mónica set out to find what was blinding us and discovered the most eye-opening tool we're not using: our own built-in curiosity. In this timely, personal guide, Mónica, the chief storyteller for the national cross-partisan depolarization organization Braver Angels, takes you to the real front lines of a crisis that threatens to grind America to a halt--broken conversations among confounded people. She shows you how to overcome the fear and certainty that surround us to finally do what only seems impossible: understand and even learn from people in your life whose whole worldview is different from or even opposed to yours. Drawing from cross-partisan conversations she's had, organized, or witnessed everywhere from the echo chambers on social media to the wheat fields in Oregon to raw, unfiltered fights with her own family on election night, Mónica shows how you can put your natural sense of wonder to work for you immediately, finding the answers you need by talking with people--rather than about them--and asking the questions you want, curiously. Whether you're left, right, center, or not a fan of labels: If you're ready to fight back against the confusion, heartbreak, and madness of our dangerously divided times--in your own life, at least--Mónica's got the tools and fresh, surprising insights to prove that seeing where people are coming from isn't just possible. It's easier than you think--Publisher's description.

How You Measure Is What You Get: Differences in Self- and External Ratings of Emotional Experiences in Home Dreams
This study demonstrates that different methods for measuring emotional experiences in dreams—self-ratings of dreams using emotion rating scales versus external ratings in the form of content analysis of narrative dream reports—can lead to strikingly different results and contradicting conclusions about the emotional content of home dreams. During 3 consecutive weeks, every morning upon awakening, 44 participants (16 men, 28 women, average age 26.9 ± 5.1 years) reported their dreams and rated their emotional experiences in those dreams using the modified Differential Emotions Scale. Two external judges rated emotional experiences in the same 552 (M = 12.55 ± 5.72) home dream reports using the same scale. Comparison of the 2 methods showed that with self-ratings dreams were rated as more emotional and more positive than with external ratings. Moreover, whereas with self-ratings the majority of dreams was rated as positively valenced, with external ratings the majority of dream reports was rated as negatively valenced. Although self- and external ratings converge, at least partially, in the measurement of negative emotional experiences, they diverge greatly in the measurement of positive emotional experiences. On one hand, this discrepancy may result from different biases inherent in the 2 measurement methods highlighting the need to develop better methods for measuring emotional experiences. On the other hand, self- and external ratings may capture different phenomena and should thus be considered complementary and used concurrently. Nevertheless, results suggest that negative emotional experiences can be measured in a more valid and reliable manner than positive emotional experiences.

Linguistic fingerprints : how language creates and reveals identity
\"How much of ourselves do we disclose when we speak or write? A person's accent may reveal, for example, whether they hail from Australia, or Ireland, or Mississippi. But it's not just where we were born-we divulge all sorts of information about ourselves and our identity through language. Level of education, gender, age, and even aspects of our personality can all be reliably determined by our vocabulary and grammar. To those who know what to look for, we give ourselves away every time we open our mouths or tap on a keyboard. But how unique is a person's linguistic identity? Can language be used to identify a specific person? To identify-or to exonerate-a murder suspect? To determine who authored a particular book? The answer to all these questions is yes. Forensic and computational linguists have developed methods that allow linguistic fingerprinting to be used in law enforcement. Similar techniques are used by literary scholars to identify the authors of anonymous or contested works of literature. Many people have heard that linguistic analysis helped to catch the Unabomber, or to unmask an anonymous editorialist-but how is it done? Linguistic Fingerprints will explain how these methods were developed and how they are used to solve forensic and literary mysteries. But these techniques aren't perfect, and the book will also include some cautionary tales about mistaken linguistic identity\"-- Provided by publisher.

Engaging Differences
Diversity is a goal for many organizations, yet it is not always connected to improved performance. This study advances diversity-performance research by examining the effect of engaging social differences. The analysis uses data from a national study of organizations containing information on the race, gender, class, and religion of each organization’s leaders as well as information on the type and content of interactions occurring among them. The data also contain multiple measures of organizational output, specifically the organization’s performance in forming alliances, developing strategies, organizing constituents, and mobilizing people. The analysis focuses on organizations with a diverse leadership team, examining the teams’ social interactions to assess whether engaging members’ social differences is associated with better performance. Additionally, qualitative data illustrate how engaging social differences impacts organizational outcomes. The study finds that teams whose members regularly participate in bridging cultural activities and discuss their social differences achieve greater output. Overall, this study indicates that an organization’s ability to realize the performance benefits of having a diverse leadership team is related to how the leaders interact with each other. The findings suggest that diverse organizations can improve their performance by ensuring that their members interact in ways that engage their social differences.
