A macroepigenetic approach to identify factors responsible for the autism epidemic in the United States

The number of children ages 6 to 21 in the United States receiving special education services under the autism disability category increased 91% between 2005 to 2010 while the number of children receiving special education services overall declined by 5%. The demand for special education services continues to rise in disability categories associated with pervasive developmental disorders. Neurodevelopment can be adversely impacted when gene expression is altered by dietary transcription factors, such as zinc insufficiency or deficiency, or by exposure to toxic substances found in our environment, such as mercury or organophosphate pesticides. Gene expression patterns differ geographically between populations and within populations. Gene variants of paraoxonase-1 are associated with autism in North America, but not in Italy, indicating regional specificity in gene-environment interactions. In the current review, we utilize a novel macroepigenetic approach to compare variations in diet and toxic substance exposure between these two geographical populations to determine the likely factors responsible for the autism epidemic in the United States

From seeing the writing on the wall, to getting together for a bowl: direct and compensating effects of Facebook use on offline associational membership

Research concerned with a decline of associational involvement has examined whether the use of social networking sites, such as Facebook, may reinvigorate or crowd out involvement in civil society. Yet, previous studies have not systematically investigated possible effects of Facebook use on associational membership. We posit that the effects of Facebook use are twofold: Facebook stimulates associational membership directly through its inherent networking features and indirectly by compensating for the lack of traditional mobilizing factors, such as social trust and internal efficacy. Relying on a probabilistic sample of German participants aged 18-49, our findings show that Facebook users are more likely to be members of voluntary associations and that Facebook use increases the likelihood of associational membership even for individuals with low levels of social trust and internal efficacy. Instead of crowding out offline associational involvement, Facebook use stimulates membership in voluntary associations, thus contributing to the vitality of civil society

A tale of two towns: A comparative study exploring the possibilities and pitfalls of social capital among people seeking recovery from substance misuse

Background: Social capital has become an influential concept in debating and understanding the modern world. Within the drug and alcohol sector, the concept of ‘recovery capital’ has gained traction with researchers suggesting that people who have access to such capital are better placed to overcome their substance use-related problems than those who do not (Cloud and Granfield, 2008), leading to requests for interventions that focus on building social capital networks (Neale & Stevenson, 2015). While accepting that the concept of social capital has enormous potential for addressing the problems associated with drug use, this paper also considers its ‘dark side’. Methods: Data were drawn from semi-structured interviews with 180 participants including 135 people who use drugs and 45 people who formerly used drugs. Results: High levels of trust, acquired through the establishment of dense social networks, are required to initiate recovery. However, these ‘strong bonds’ may also lead to the emergence of what is perceived by others as an exclusive social network that limits membership to those who qualify and abide by the ‘rules’ of the recovery community, particularly around continuous abstinence. Conclusions: Depending on the nature of the networks and the types of links participants have into them being socially connected can both inhibit and encourage recovery. Therefore, the successful application of social capital within the drugs and alcohol field requires a consideration of not only the presence or absence of social connections but their nature, the value they produce, and the social contexts within which they are developed
