Network structures are everywhere, including but not limited to applications in biological, physical and social sciences, information technology, and optimization. Network robustness is of crucial importance in all such applications. Research on this topic relies on finding a suitable measure and use this measure to quantify network robustness. A number of distance-based graph invariants, also known as topological indices, have recently been incorporated as descriptors of complex networks. Among them the Wiener type indices are the most well known and commonly used such descriptors...

AIMS: The ability to recognise a mental illness has important implications as it can aid in timely and appropriate help-seeking, and ultimately improve outcomes for people with mental illness. This study aims to explore the association between recognition and help-seeking preferences and stigmatising attitudes, for alcohol abuse, dementia, depression, obsessive-compulsive disorder (OCD) and schizophrenia, using a vignette-based approach. METHODS: This was a population-based, cross-sectional survey conducted among Singapore Residents (n = 3006) aged 18-65 years...

BACKGROUND: The goal of stroke rehabilitation has shifted from mere survival of a victim to how well a survivor can be effectively reintegrated back into the community. OBJECTIVES: The present study determined the level of satisfaction with community reintegration (CR) and related factors among Nigerian community-dwelling stroke survivors (CDSS). METHODS: This was a cross-sectional survey of 71 volunteering CDSS (35 males, 36 females) from selected South-Eastern Nigerian communities...

Trust in government has long been viewed as an important determinant of citizens' compliance with public health policies, especially in times of crisis. Yet evidence on this relationship remains scarce, particularly in the developing world. We use results from a representative survey conducted during the 2014-15 Ebola Virus Disease (EVD) epidemic in Monrovia, Liberia to assess the relationship between trust in government and compliance with EVD control interventions. We find that respondents who expressed low trust in government were much less likely to take precautions against EVD in their homes, or to abide by government-mandated social distancing mechanisms designed to contain the spread of the virus...

Previous studies have suggested the benefits of physical exercise for patients on dialysis. We conducted the Exercise Introduction to Enhance Performance in Dialysis trial, a 6-month randomized, multicenter trial to test whether a simple, personalized walking exercise program at home, managed by dialysis staff, improves functional status in adult patients on dialysis. The main study outcomes included change in physical performance at 6 months, assessed by the 6-minute walking test and the five times sit-to-stand test, and in quality of life, assessed by the Kidney Disease Quality of Life Short Form (KDQOL-SF) questionnaire...

Increasingly, health communication scholars are attending to how hospital built environments shape communication, patient care processes, and patient outcomes. This multimethod study was conducted on two floors of a newly designed urban hospital. Nine focus groups interviews were conducted with 35 health care professionals from 10 provider groups. Seven of the groups were homogeneous by profession or level: nursing (three groups), nurse managers (two groups), and one group each of nurse care technicians ("techs") and physicians...

The vast majority of public health students exhibit the kind of 'clean living' that is routinely advocated as highly desirable by health promoters. However, this social and cultural distance from many of the most important health issues faced in our society creates a barrier for understanding and working with other population groups. Insider status, knowledge and understanding is essential in developing true insight in developing culturally appropriate interventions. Referencing Rose's influential prevention paradox, a revision is suggested stating that prevention measures are often developed by individuals outside the population in question and may offer little actual benefit to that population...

Studies of the frequency of heterozygous carriers for common inherited diseases of haemoglobin in over 7500 adolescent children in 25 districts in Sri Lanka have disclosed a highly significant variation over very short geographical distances. A further analysis of these findings, including their relationship to the past frequency and distribution of malaria, climatic variation, altitude, ethnic origin and consanguinity rates, have provided evidence regarding the evolutionary basis for the variable distribution of these conditions over short distances...

BACKGROUND: Under-five mortality, which is the probability of a child dying before their fifth birthday, is of concern in Zambia as infant and child mortality rates are important social indicators. Displaced population in camps provide a basis for under-five mortality surveillance because detailed registration databases have been developed. Additionally, health data routinely collected on mortality allowed for a review of mortality trends and identification of correlating factors to under-five mortality...

BACKGROUND: Public attitudes to mental illness could influence how the public interact with, provide opportunities for, and help people with mental illness. AIMS: This study aims to explore the underlying factors of the Attitudes to Mental Illness questionnaire among the general population in Singapore and the socio-demographic correlates of each factor. METHODS: From March 2014 to April 2015, a nation-wide cross-sectional survey on mental health literacy with 3,006 participants was conducted in Singapore...

Interpersonal space is a nonverbal indicator of affiliation and closeness. In this study we investigated the effects of oxytocin (OT), a neuropeptide known for its social role in humans, on interpersonal space. In a double blind placebo controlled study we measured the effect of intranasal OT on the personal distance preferences of different familiar (friend) and unfamiliar (stranger) protagonists. Behavioral results showed that participants preferred to be closer to a friend than to a stranger. Intranasal OT was associated with an overall distancing effect, but this effect was significant for the stranger and not for the friend...

BACKGROUND: Stigma associated with mental illness (MI) results in underutilization of mental health care. We must understand factors contributing to stigma to shape anti-stigma campaigns. AIMS: To investigate the factors influencing stigma in university students. METHOD: Undergraduate psychology students completed measures on causal attribution, stigma, social distance, implicit person theory (IPT), and familiarity. RESULTS: The hypothesis was partially supported; people who felt personality traits were unchangeable (i...

Human behaviour in various circumstances mirrors the corresponding brain connectivity patterns, which are suitably represented by functional brain networks. While the objective analysis of these networks by graph theory tools deepened our understanding of brain functions, the multi-brain structures and connections underlying human social behaviour remain largely unexplored. In this study, we analyse the aggregate graph that maps coordination of EEG signals previously recorded during spoken communications in two groups of six listeners and two speakers...

CONTEXT: Conventional wisdom has it that everyone on earth is on average only six steps away from knowing any other person through 'a friend of a friend'. On a local level, however, many people experience that most of their acquaintances know each other. It is thus hard to imagine how such a highly clustered group could be so well connected to the rest of the world. In this paper, we investigate how co-authorship connects scholars in medical education and whether the six degrees of separation hypothesis also applies to the network of authors in the field...

Ronald Kwon, Augustine Kposowa
Multi-racial (mixed-race) people constitute a growing percentage of the United States (US) population. The study reported in this paper used residential segregation measures as a proxy for social distance, to examine whether segregation levels of multi-racial groups differ from those of mono-racial groups in the US in 2010. First, we find that all multi-racial groups considered in the study experience lower levels of segregation at county level than their mono-racial counterparts. However, black-whites and Hispanic-whites experience higher levels of segregation than other multi-racial groups...

How humans resolve non-trivial tradeoffs in their navigational choices between the social interactions (e.g., the presence and movements of others) and the physical factors (e.g., spatial distances, route visibility) when escaping from threats in crowded confined spaces? The answer to this question has major implications for the planning of evacuations and the safety of mass gatherings as well as the design of built environments. Due to the challenges of collecting behavioral data from naturally-occurring evacuation settings, laboratory-based virtual-evacuation experiments have been practiced in a number of studies...

PURPOSE: The effects of three anti-stigma strategies for stuttering-contact (hearing personal stories from an individual who stutters), education (replacing myths about stuttering with facts), and protest (condemning negative attitudes toward people who stutter)-were examined on attitudes, emotions, and behavioral intentions toward people who stutter. METHOD: Two hundred and twelve adults recruited from a nationwide survey in the United States were randomly assigned to one of the three anti-stigma conditions or a control condition...

In social interactions, humans are expected to regulate interpersonal distance in response to the emotion displayed by others. Yet, the neural mechanisms implicated in approach-avoidance tendencies to distinct emotional expressions have not been fully described. Here, we investigated the neural systems implicated in regulating the distance to different emotions, and how they vary as a function of empathy. Twenty-three healthy participants assessed for psychopathic traits underwent fMRI scanning while they viewed approaching and withdrawing angry, fearful, happy, sad and neutral faces...

To investigate the neural basis of socio-economic behaviors in birds, we examined the effects of bilateral electrolytic lesions of arcopallium (Arco, the major descending pallial area of the avian telencephalon) and the surrounding nuclei in domestic chicks. We tested foraging effort (running distance) in an I-shaped maze with two food patches that delivered food in a biased manner according to a variable interval schedule. Normally, chicks run back and forth between the patches, and the patch use time matches the respective food delivery rate...
