Are You Being Rejected or Excluded? Insights from Neuroimaging Studies Using Different Rejection Paradigms
No full textRejection sensitivity is the heightened tendency to perceive or anxiously expect disengagement from others during social interaction. There has been a recent wave of neuroimaging studies of rejection. The aim of the current review was to determine key brain regions involved in social rejection by selectively reviewing neuroimaging studies that employed one of three paradigms of social rejection, namely social exclusion during a ball-tossing game, evaluating feedback about preference from peers and viewing scenes depicting rejection during social interaction. A cross the different paradigms of social rejection, there was concordance in regions for experiencing rejection, namely dorsal anterior cingulate cortex (ACC), subgenual ACC and ventral ACC. Functional dissociation between the regions for experiencing rejection and those for emotion regulation, namely medial prefrontal cortex, ventrolateral prefrontal cortex (VLPFC) and ventral striatum, was evident in the positive association between social distress and regions for experiencing rejection and the inverse association between social distress and the emotion regulation regions. The paradigms of social exclusion and scenes depicting rejection in social interaction were more adept at evoking rejection-specific neural responses. These responses were varyingly influenced by the amount of social distress during the task, social support received, self-esteem and social competence. Presenting rejection cues as scenes of people in social interaction showed high rejection sensitive or schizotypal individuals to under-activate the dorsal ACC and VLPFC, suggesting that such individuals who perceive rejection cues in others down-regulate their response to the perceived rejection by distancing themselves from the scene

Constructing models of alcohol and sexual health literacy in adolescence.
No full textIn the UK, research has highlighted the need for improved education in alcohol and sexual health in the adolescent population. Consequently, Relationships and Sex Education and Health Education were made compulsory in 2019. However, preceding research highlighted that school-based alcohol and sexual health education was ill-suited to building associated health skills and competencies. Health literacy as a concept aims to address these issues by providing a framework within which health related competencies and outcomes can be developed. Consequently, the aim of this research was to develop models of alcohol and sexual health literacy in adolescents and further interrogate the use of such models in education, exploring the barriers to developing alcohol and sexual health literacy in adolescents though formal education. A pragmatic, mixed methods approach was utilised to explore the research questions. The study contributed to the field of research by creating robust, theory-based models of alcohol and sexual health literacy and discovering the following: • Current measures of adolescent health literacy are poorly designed, often only accounting for functional health literacy. • There are many barriers that need to be overcome to effectively deliver alcohol and sexual health education in schools, specifically, that competencies in alcohol and sexual health are perceived as challenging to teach and measure within a school setting. • Internationally, curriculum guidelines tend to focus on the risks associated with alcohol and sexual health and fall short in building competencies over knowledge and in aiding educators with instruction. • Introduction of compulsory Relationships and Sexual Health Education and Health Education in the UK will have little significant impact if it is not supported with more training and support for educators.These findings and the models produced have significant connotations for the design and delivery of alcohol and sexual health education in schools

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
