Neural Correlates of Pathological Gamblers Preference for Immediate Rewards During the Iowa Gambling Task: An fMRI Study

The Iowa Gambling Task (IGT) involves exploratory learning via rewards and penalties, where most advantageous task performance requires subjects to forego potential large immediate rewards for small longer-term rewards to avoid larger punishments. Pathological gambling (PG) subjects perform worse on the IGT compared to controls, relating to their persistence at high risk decisions involving the continued choice of potential large immediate rewards despite experiencing larger punishments. We wished to determine if neural processing of risk and reward within striatal and frontal cortex is associated with this behaviour observed in PG. Functional magnetic resonance imaging (fMRI) was used to assess brain activity in response to a computerized version of the IGT. Thirteen male PG subjects with no active comorbidities were compared to 13 demographically matched control subjects. In agreement with previous behavioural studies, PG subjects performed worse on the IGT and made more high-risk choices compared to controls, particularly after experiencing wins and losses. During high-risk gambling decisions, fMRI demonstrated that PG subjects exhibited relatively increased frontal lobe and basal ganglia activation, particularly involving the orbitofrontal cortex (OFC), caudate and amygdala. Increased activation of regions encompassing the extended reward pathway in PG subjects during high risk choices suggests that the persistence of PG may be due to the increased salience of immediate and greater potential monetary rewards relative to lower monetary rewards or potential future losses. Whether this over activation of the reward pathway is associated with the development of PG warrants further investigation.     

Changes following Premarital Education for Couples with Differing Degrees of Future Marital Risk

The present study explored changes in individuals' relationship cognitions and behaviors following premarital education for couples with different risk profiles. The sample consisted of 63 couples who completed the PREPARE program and were classified for future marital risk based on dyadic information. A significant interaction effect was found between risk and time, with individuals in relationships classified as high risk exhibiting greater change at 4 weeks postprogram compared to low‐risk individuals. Perceived helpfulness of topics also varied by couple type. Findings provide support for adapting premarital education programs for high‐risk couples and offer clinicians and educators specific insights for areas of emphasis when working with different types of couples.     

Revisiting the digital divide in Canada: the impact of demographic factors on access to the internet,level of online activity,and social networking site usage

The present study relies on the 2010 Canadian Internet Use Survey to investigate differences in people's access to the internet and level of online activity. The study not only revisits the digital divide in the Canadian context, but also expands current investigations by including an analysis of how demographic factors affect social networking site (SNS) adoption. The findings demonstrate that access to the internet reflects existing inequalities in society with income, education, rural/urban, immigration status, and age all affecting adoption patterns. Furthermore, the results show that inequality in access to the internet is now being mimicked in the level of online activity of internet users. More recent immigrants to Canada have lower rates of internet access; however, recent immigrants who are online have significantly higher levels of online activity than Canadian born residents and earlier immigrants. Additionally, women perform fewer activities online than men. People's use of SNSs differs in terms of education, gender, and age. Women were significantly more likely to use SNSs than men. Interestingly, high school graduates had the lowest percentage of adoption compared to all other education categories. Current students were by far the group that utilized SNSs the most. Canadian born, recent, and early immigrants all showed similar adoption rates of SNSs. Age is a strong predictor of SNS usage, with young people relying heavily on SNSs in comparison to those aged 55+. The findings demonstrate that the digital divide not only persists, but has expanded to include inequality in the level of online activity and SNS usage.     

Legal Mobilisation and Justice: Insights from the Constitutional Court Case on International Standard Schools in Indonesia

Analysis of the role of courts in shaping access to justice in Indonesia has emphasised the role of judges and the incentives created for them by courts' institutional design. Alternatively, it has focused on individual justice-seekers and their capacities to choose between alternative pathways through the legal repertoire. In this paper, we suggest that ‘support structures for legal mobilisation’ (SSLMs) have also played an important role in shaping access to justice by influencing both the potential for legal mobilisation and the type of justice sought. In making this argument, we focus on a recent Constitutional Court case on ‘international standard schools’. In this case, a group of parents were able to mobilise for legal action only because NGOs provided the required technical expertise and financial resources while the central involvement of an anti-corruption NGO in the SSLM shifted the focus from parents' concerns about discrimination to corruption.     

“How Could I Have Done This?” Thoughts of Mothers of Children with Fetal Alcohol Syndrome

Biological mothers of children with fetal alcohol syndrome (FAS) must cope with the struggles of parenting a child with special needs with the knowledge that their children’s problems are due to their alcohol use during pregnancy. Qualitative interviews were conducted by telephone with 11 biological mothers of children with FAS. This group of mothers understood their use of alcohol during pregnancy through reliance on the disease model, inaccurate or incomplete knowledge of the consequences of drinking during pregnancy, the advice of others, and a lack of awareness of the pregnancy.     

How leader humility helps teams to be humbler,psychologically stronger,and more effective: A moderated mediation model

We hypothesize that (a) the level of humility expressed by leaders predicts team performance through, serially, team humility and team PsyCap, and (b) the strength (i.e., consensus within the team) of the leader humility, team humility and team PsyCap moderates the paths of that hypothesized model. A sample comprising 82 teams (82 leaders; 332 team members) was collected. Team members reported leader humility, team humility and team PsyCap. Leaders reported team performance. To handle the risks of common method bias, each mediating path of the hypothesized model is based on data from two different subsamples within each team. Our model's most novel theoretical contribution is the (moderated mediated) connection between leader humility, collective humility, and team PsyCap, and this was consistently supported in our data. Our inconsistent findings dealing with the relationship between team PsyCap and performance is well established in the literature and our results in both sub-samples were in the theorized direction. The study contributes to understand why, how and when humble leaders are more effective.     

神机妙算

二小是我的表弟。说是表弟，其实只比我晚出生两天。 我们都是家里的老二，我上面有一个姐姐，他上面有一个哥哥。从前乡下人家，父母对第一个孩子，都是期盼且欣喜的。到了第二个孩子，那期盼与欣喜的心，已淡了，给予的疼爱，也是有的，却少了细致与周到。我们是那么不引人注目，像野地里的芨芨草。兀自顽强地生长着。
