It has recently become possible to study the dynamics of information diffusion in techno-social systems at scale, due to the emergence of online platforms, such as Twitter, with millions of users. One question that systematically recurs is whether information spreads according to simple or complex dynamics: does each exposure to a piece of information have an independent probability of a user adopting it (simple contagion), or does this probability depend instead on the number of sources of exposure, increasing above some threshold (complex contagion)? Most studies to date are observational and, therefore, unable to disentangle the effects of confounding factors such as social reinforcement, homophily, limited attention, or network community structure...

BACKGROUND: To examine psychological health and perceived social support in patients with chronic edema (CE). METHODS AND RESULTS: A random sample of 107 patients with CE was group matched for age and gender with 102 community controls. The cases had swelling of the arm (38%) and leg (61%) and midline swelling (14%). Cases were more likely to be single or divorced/separated (p = 0.041) and have reduced mobility (p < 0.001). They had significantly poorer overall health related quality of life (HRQoL), in particular physical functioning (p = 0...

With the rise of online social networking, social relationships are increasingly developed and maintained in a digital domain. Drawing conclusions about the impact of the digital world on loneliness is difficult because there are contradictory findings, and cross-sectional studies dominate the literature, making causation difficult to establish. In this review, we present our theoretical model and propose that there is a bidirectional and dynamic relationship between loneliness and social Internet use. When the Internet is used as a way station on the route to enhancing existing relationships and forging new social connections, it is a useful tool for reducing loneliness...

Diagnostic classification systems in psychiatry have continued to rely on clinical phenomenology, despite limitations inherent in that approach. In view of these limitations and recent progress in neuroscience, the National Institute of Mental Health (NIMH) has initiated the Research Domain Criteria (RDoC) project to develop a more neuroscientifically based system of characterizing and classifying psychiatric disorders. The RDoC initiative aims to transform psychiatry into an integrative science of psychopathology in which mental illnesses will be defined as involving putative dysfunctions in neural nodes and networks...

In case of severe illnesses such as dementia it is important to keep inquiring how the person concerned and his or her social network view and experience the illness. For conditions that cannot be cured, family and social ties have proven to be the most important factors in experiencing quality of life. In case of dementia, people can be distressed when they feel excluded from such conversations. Family members are often only approached in their roles as informal caregivers or representatives. However, by also discussing other roles in relationships, families and friendships and by alternating in these conversations between the positions of so-called expert and advisor, doctors can contribute to preventing connections from breaking off prematurely...

Background Through the concept of ageism, we highlight and explain how the society prejudices the elderly. WHO classifies 12 most common stereotypes pertaining to old age. Elderly people are being excluded from social life due to their chronological age rather than any actual reduced physical and/or mental ability. Some of these stereotypes are directly related to the (un)willingness and the ability of the elderly to use technology in everyday life. Objectives The study presented in this article aims to explain the phenomenon of technology use among elderly people who had had a stroke...

Because mobile ad hoc networks have characteristics such as lack of center nodes, multi-hop routing and changeable topology, the existing checkpoint technologies for normal mobile networks cannot be applied well to mobile ad hoc networks. Considering the multi-frequency hierarchy structure of ad hoc networks, this paper proposes a hybrid checkpointing strategy which combines the techniques of synchronous checkpointing with asynchronous checkpointing, namely the checkpoints of mobile terminals in the same cluster remain synchronous, and the checkpoints in different clusters remain asynchronous...

Recent studies show the remarkable power of fine-grained information disclosed by users on social network sites to infer users' personal characteristics via predictive modeling. Similar fine-grained data are being used successfully in other commercial applications. In response, attention is turning increasingly to the transparency that organizations provide to users as to what inferences are drawn and why, as well as to what sort of control users can be given over inferences that are drawn about them. In this article, we focus on inferences about personal characteristics based on information disclosed by users' online actions...

Two studies evaluated the lay belief that women feel particularly negatively about other women in the workplace and particularly in supervisory roles. The authors tested the general proposition, derived from social identity theory (Tajfel & Turner, 1979, 2004), that women, compared to men, may be more supportive of other women in positions of authority, whereas men would respond more favorably to other men than to women in positions of authority. Consistent with predictions, data from an online experiment (n = 259), in which the authors randomly assigned men and women to evaluate identical female (vs...

Human behaviors exhibit ubiquitous correlations in many aspects, such as individual and collective levels, temporal and spatial dimensions, content, social and geographical layers. With rich Internet data of online behaviors becoming available, it attracts academic interests to explore human mobility similarity from the perspective of social network proximity. Existent analysis shows a strong correlation between online social proximity and offline mobility similarity, namely, mobile records between friends are significantly more similar than between strangers, and those between friends with common neighbors are even more similar...

BACKGROUND: Health systems worldwide struggle to identify, adopt, and implement in a timely and system-wide manner the best-evidence-informed-policy-level practices. Yet, there is still only limited evidence about individual and institutional best practices for fostering the use of scientific evidence in policy-making processes The present project is the first national-level attempt to (1) map and structurally analyze-quantitatively-health-relevant policy-making networks that connect evidence production, synthesis, interpretation, and use; (2) qualitatively investigate the interaction patterns of a subsample of actors with high centrality metrics within these networks to develop an in-depth understanding of evidence circulation processes; and (3) combine these findings in order to assess a policy network's "absorptive capacity" regarding scientific evidence and integrate them into a conceptually sound and empirically grounded framework...

Sign language is an essential medium for everyday social interaction for deaf people and plays a critical role in verbal learning. In particular, language development in those people should heavily rely on the verbal short-term memory (STM) via sign language. Most previous studies compared neural activations during signed language processing in deaf signers and those during spoken language processing in hearing speakers. For sign language users, it thus remains unclear how visuospatial inputs are converted into the verbal STM operating in the left-hemisphere language network...

Steroids exert their actions by binding to the glucocorticoid, mineralocorticoid, androgen, estrogen and progesterone classes of receptors. Despite an exponential increase in our knowledge of steroid receptors, their interactions with other molecules, subcellular location and functions still need further elucidation. To unravel the mechanism(s) of action of the steroid hormones, as well as the function of their cognate nuclear receptors, an interaction network was created (henceforth referred to as "R1 Interactome")- illustrating that robust interactions have been preserved in rodents, frog, zebra fish and drosophila...

OBJECTIVE: The findings of previous research that examined relationships between popularity and alcohol use in adolescents have been mixed, and few hypotheses have proposed mechanisms for this relationship. The current study expands on previous literature (a) by examining a possible mechanism that can explain the relation between popularity and alcohol use (home access to alcohol) and (b) by using another sociometric measure ("betweenness"), beyond popularity, that may relate more to home alcohol access...
