Sociolinguists have long argued that social context influences language use in all manner of ways, resulting in lects 1 . This paper explores a text classification problem we will call lect modeling, an example of what has been termed computational sociolinguistics. In particular, we use machine learning techniques to identify social power relationships between members of a social network, base...

While direct social ties have been intensely studied in the context of computer-mediated social networks, indirect ties (e.g., friends of friends) have seen little attention. Yet in real life, we often rely on friends of our friends for recommendations (of good doctors, good schools, or good babysitters), for introduction to a new job opportunity, and for many other occasional needs. In this wo...

It is remarkable to analyze the growth and evolution of online social networks where either we consider the marketing strategy or new services being offered, also from a scientific viewpoint, since their erect...

How does lacking vs. possessing power in a social exchange affect people's trust in their exchange partner? An answer to this question has broad implications for a number of exchange settings in which dependence plays an important role. Here, we report on a series of experiments in which we manipulated participants' power position in terms of structural dependence and observed their trust perce...

Inclusive fitness theory has been very successful in predicting and explaining much of the observed variation in the reproductive characteristics of insect societies. For example, the theory correctly predicts sex-ratio biasing by workers in relation to the queen's mating frequency. However, within an insect society there are typically multiple reproductive optima, each corresponding to the int...

Possessing power contributes to high self-esteem, but how power enhances self-esteem is still unknown. As power is associated with both self-oriented goals and social-responsibility goals, we proposed that power predicts self-esteem through two positive personal and interpersonal results: authenticity and relationship satisfaction. Three studies were carried out with a total of 505 Chinese part...

Social Network Analysis traditionally examines the graph of a communications network to identify key individuals based on the pattern of their interactions, but there is a limit to the level of detail which can be inferred from metadata alone. Message content is a richer source of data, and can provide an indication of the relationship between a pair of communicants. An individual’s language us...

Mancur Olson’s book, The Rise and Decline of Nations [45], used ideas from his earlier Logic of Collective Action [44] to argue that entrenched interest groups in a polity could induce economic sclerosis, or slow growth. These ideas seemed relevant to the perceived relative decline of the U.S. and Britain during the 1970’s. Five years later, Paul Kennedy’s The Rise and Fall of the Great Powers ...
