Cognitive Deficits in Executive Functions and Decision-Making Impairments Cluster Gambling Disorder Sub-types

To identify Gambling Disorder (GD) subtypes, in a population of men seeking treatment for GD, according to specific executive function domains (i.e., cognitive flexibility, inhibition and working memory as well as decision making) which are usually impaired in addictive behaviors. A total of 145 males ranging from 18 to 65 years diagnosed with GD were included in this study. All participants completed: (a) a set of questionnaires to assess psychopathological symptoms, personality and impulsivity traits, and (b) a battery of neuropsychological measures to test different executive functioning domains. Two clusters were identified based on the individual performance on the neuropsychological assessment. Cluster 1 [n = 106; labeled as Low Impaired Executive Function (LIEF)] was composed by patients with poor results in the neuropsychological assessment; cluster 2 patients [n = 46; labeled as High Impaired Executive Function (HIEF)] presented significantly higher deficits on the assessed domains and performed worse than the ones of LIEF cluster. Regarding the characterization of these two clusters, patients in cluster 2 were significantly older, unemployed and registered higher mean age of GD onset than patients in cluster 1. Additionally, patients in cluster 2 also obtained higher psychopathological symptoms, impulsivity (in both positive and negative urgency as well as sensation seeking) and some specific personality traits (higher harm avoidance as well as lower self-directedness and cooperativeness) than patients in cluster 1. The results of this study describe two different GD subtypes based on different cognitive domains (i.e., executive function performance). These two GD subtypes display different impulsivity and personality traits as well as clinical symptoms. The results provide new insight into the etiology and characterization of GD and have the potential to help improving current treatments.     

When community becomes an agent of educational support: communicative research on Learning Communities in Catalonia

Educational support is a key component of any inclusive school. However, many traditional forms of support have been proven ineffective and even exclusionary for the most vulnerable students and their families. This article presents the results of a study conducted over four years by a diverse research team of university professors, PhD students, teachers and head teachers of schools operating as Learning Communities in Catalonia, Spain. The communicative and dialogic approach of these schools offers an alternative understanding of educational support, which is influenced to a great extent by the creation of networks that include participation by diverse agents. The current article provides a theoretical grounding for this approach to support. The article describes the role of different agents from the community and analyses the main effects of this approach and students’ experiences. Finally, a proposal for a dialogic orientation for educational support is discussed.     

Exploring the Relationship between Reward and Punishment Sensitivity and Gambling Disorder in a Clinical Sample: A Path Modeling Analysis

Most individuals will gamble during their lifetime, yet only a select few will develop gambling disorder. Gray’s Reinforcement Sensitivity Theory holds promise for providing insight into gambling disorder etiology and symptomatology as it ascertains that neurobiological differences in reward and punishment sensitivity play a crucial role in determining an individual’s affect and motives. The aim of the study was to assess a mediational pathway, which included patients’ sex, personality traits, reward and punishment sensitivity, and gambling-severity variables. The Sensitivity to Punishment and Sensitivity to Reward Questionnaire, the South Oaks Gambling Screen, the Symptom Checklist-Revised, and the Temperament and Character Inventory-Revised were administered to a sample of gambling disorder outpatients (N = 831), diagnosed according to DSM-5 criteria, attending a specialized outpatient unit. Sociodemographic variables were also recorded. A structural equation model found that both reward and punishment sensitivity were positively and directly associated with increased gambling severity, sociodemographic variables, and certain personality traits while also revealing a complex mediational role for these dimensions. To this end, our findings suggest that the Sensitivity to Punishment and Sensitivity to Reward Questionnaire could be a useful tool for gaining a better understanding of different gambling disorder phenotypes and developing tailored interventions.     

Examining Discrimination,Ethnic‐Racial Identity Status,and Youth Public Regard Among Black,Latino, and White Adolescents

How positively adolescents believe others feel about their ethnic‐racial group (i.e., public regard) is an important part of their ethnic‐racial identity (ERI), which is likely informed by contextual and individual factors. Using cluster analyses to generate ERI statuses among Black, Latino, and White adolescents (n = 1,378), we found that associations between peer versus adult discrimination and public regard varied across ERI status and ethnic‐racial group. However, among all adolescents, an achieved ERI (i.e., having explored ethnicity‐race and having a clear sense about its personal meaning) buffered the negative association between adult discrimination and public regard, but not between peer discrimination and public regard. Implications for understanding the interplay between contextual and individual factors for public regard are discussed.     

American Indian Grand-Families: Trauma and Services

Since the United States Census Bureau began collecting data regarding grandparents raising their grandchildren, the American Indian and Alaska Native (AI/AN) population has had the highest proportion of families led by grandparents as the primary caregivers of their grandchildren. Despite this, research into AI/AN grand-families is limited. To begin to fill this gap, this qualitative study of 49 AI/AN grandparents raising grand-families (GFs) was conducted in an urban area with one of the highest AI/AN populations in the United States. Results indicated that loss and trauma within the middle generation is a central theme for GF formation. Such GFs also reported using a variety of services spanning state, tribal, and urban AI/AN programs, with educational support as a primary need articulated for their grandchildren. Surprisingly, enculturation was not mentioned as a primary driver of GF formulation. The study suggests a need for further exploration of the needs of urban-based AI/AN GFs, and that service providers must be aware of such issues when working with AI/AN GFs.     

Differential evolutionary algorithm in the construction process of optimal experimental designs

This article shows how a differential evolution algorithm can be used to find statistical designs under several optimality criteria as A, D, and T. The general algorithm of differential evolution is described and then applied on constructing optimal designs for several well-known models and compare them with those already available by other algorithms, in terms of relative efficiency. Moreover, the great effect of population size in the running of this algorithm establishes a precedent in the use of differential evolution algorithms over genetic algorithms.     

Assessing Type I error and power of multistate Markov models for panel data—A simulation study

Ordinal outcomes collected at multiple follow-up visits are common in clinical trials. Sometimes, one visit is chosen for the primary analysis and the scale is dichotomized amounting to loss of information. Multistate Markov models describe how a process moves between states over time. Here, simulation studies are performed to investigate the Type I error and power characteristics of multistate Markov models for panel data with limited non-adjacent state transitions. The results suggest that the multistate Markov models preserve the Type I error and adequate power is achieved with modest sample sizes for panel data with limited non-adjacent state transitions.     

Is coverage enough? Persistent health disparities in marginalised Latino border communities

ABSTRACT

What has been the fate of those living in the place once dubbed the ‘county that needs the Affordable Care Act the most’? This article presents results from a longitudinal, five-year ethnographic study of healthcare access in the Rio Grande Valley of Texas. It explores reasons why this region along the U.S./Mexico border has the highest rate of uninsured persons in the country and remains among the most medically underserved, despite some increases in coverage accompanying the Affordable Care Act (ACA). It argues that the convergence of healthcare and immigration policy, framed by a unique regional history and social environment, has had multiple direct and indirect impacts on health and healthcare access. It examines the impact of the ACA on access for Latino immigrants and mixed-status households, which contain a mix of citizens, legal residents, and undocumented persons. It argues that the ACA aided in shifting the conversation to promoting private insurance coverage and away from more fundamental access barriers for low-income working populations ineligible for its benefits. This has eclipsed discussions about fundamental causes of persistent and highly racialised health disparities.     

Income distribution,economic growth and European integration

In this paper I discuss recent theories on the relationship between growth and inequality, and ask whether the two move together or not. Output growth can be due to increases in physical capital, human capital, employment or the level of technology, and I argue that each of these represents a mechanism that relates our two variables of interest. The European integration process has represented a major policy change that has affected not only the opportunities for growth but also the constraints faced by national governments. We can then ask whether such integration has had an effect on inequality, and to what extent it has resulted in a conflict between productive efficiency and distributive considerations.
