Neuromarketing as a scale validation tool: Understanding individual differences based on the style of processing scale in affective judgements

This paper revisits a well-cited and widely applied consumer scale, Style of Processing (SOP) (Childers et al., Journal of Consumer Research, 1985, 12, 125), that has been used to investigate individual differences in processing visual versus verbal information in marketing. The scale has advanced knowledge in fields related to marketing communications, product development, psychology, advertising, education and learning theories, shedding light on our understanding of consumer psychology related to persuasion, comprehension, memory, and other consumer cognitive processes involving information. In a research dialog that took place in 2008, a need for further SOP validation was suggested using a neuromarketing approach. We took this call forward and conducted an event-related-potential (ERP) experimental research study using electroencephalogram (EEG) to validate the SOP scale, focusing on differential affective processing between verbalizers and visualizers. We not only demonstrate how neuromarketing tools can be utilized to provide evidence for scale validity, providing advantages over self-reported measures; but more importantly, address issues related to understanding differential fluency effects that exist between visualizers and verbalizers. Behavioral data revealed varying reaction times to emotional stimuli of a pictorial nature. We further identify two ERP components in our data, early left anterior negativity (ELAN) and late negative slow wave (LNSW), that differentiate individual processing fluency in affective versus evaluative-based judgements. Findings confirmed the construct validity of the SOP scale and enhance our understanding of individual differences in emotional processing of pictorial information

A brain-derived MeCP2 complex supports a role for MeCP2 in RNA processing

Mutations in MECP2 (methyl-CpG-binding protein 2) are linked to the severe postnatal neurodevelopmental disorder RTT (Rett syndrome). MeCP2 was originally characterized as a transcriptional repressor that preferentially bound methylated DNA; however, recent results indicate MeCP2 is a multifunctional protein. MeCP2 binding is now associated with certain expressed genes and involved in nuclear organization as well, indicating that its gene regulatory function is context-dependent. In addition, MeCP2 is proposed to regulate mRNA splicing and a mouse model for RTT shows aberrant mRNA splicing. To further understand MeCP2 and potential roles in RTT pathogenesis, we have employed a biochemical approach to identify the MeCP2 protein complexes present in the mammalian brain. We show that MeCP2 exists in at least four biochemically distinct pools in the brain and characterize one novel brain-derived MeCP2 complex that contains the splicing factor Prpf3 (pre-mRNA processing factor 3). MeCP2 directly interacts with Prpf3 in vitro and in vivo and many MECP2 RTT truncations disrupt the MeCP2-Prpf3 complex. In addition, MeCP2 and Prpf3 associate in vivo with mRNAs from genes known to be expressed when their promoters are associated with MeCP2. These results support a role for MeCP2 in mRNA biogenesis and suggest an additional mechanism for RTT pathophysiology

Evaluation Development and Use in Social Work Practice

Background: Social workers entering the profession typically receive little, if any, content or training on evaluation practice. This is, in part, due to limited course offerings outside of the typical courses in most schools of social work. In addition, practicing social workers who often serve in the role as field instructors have not fully embraced the use of research in practice, and tend to employ less rigorous evaluative methods.   Purpose: The purpose of this study was to explore the development and use of evaluation knowledge among social work practitioners who supervise social work students.   Setting: Not applicable.   Intervention: Not applicable.   Research Design: A mixed method, sequential research design within the context of an exploratory study was used to determine factors that facilitate evaluation, identify and prioritize evaluation competencies, and determine the extent to which evaluation constructs contribute to self efficacy, evaluation competency, evaluation influence, and leadership behaviors.   Data Collection and Analysis: A web-based survey was used followed by a participatory method that included the use of a web-based software to identify and prioritize activities that contribute to the development of evaluation knowledge and skill.   Findings: Results suggest social work education has a critical role in promoting evaluation practice, establishing evaluation practice competencies, and using evaluation results to inform policy and practice.   Keywords: social work practice, field education, evaluation practice, Council on Social Work Education (CSWE), Educational Policy, and Accreditation Standards (EPAS

Bodies, building and bricks: Women architects and builders in eight eco-communities in Argentina, Britain, Spain, Thailand and USA

Eco-building is a male domain where men are presumed to be better builders and designers, more men than women build and women find their design ideas and contributions to eco-building are belittled. This article suggests that a focus on bodies, embodiment and the ‘doing’ of building is a potentially productive way to move beyond current gender discrimination. This article makes three key interventions using empirical material from eight case studies of eco-communities in Britain, Thailand, Spain, the USA and Argentina. First, it uses a focus on eco-communities to illustrate the enduring persistence of gender divisions in architecture and building. Second, by using multi-site examples of eco-communities from diverse countries this article finds more commonalities than differences in gender discrimination across cultures and nationalities. Third, it outlines three spaces of opportunity through which more gender-neutral approaches are being developed in eco-building: (1) in challenging the need for ‘strong’ bodies, (2) by practising more embodied ways of building and (3) by making visible women's bodies in building. The ‘doing’ and manual aspect of eco-building is unfamiliar for many (not just women) and interviewees commented on the need to (re)learn how to be practical and to understand the physical possibilities (and limitations) of their bodies

Variations in policies for accessing elective musculoskeletal procedures in the English National Health Service:A documentary analysis

OBJECTIVE: The overall aim of this study was to investigate how commissioning policies for accessing clinical procedures compare in the context of the English National Health Service. Our primary objective was to compare policy wording and categorise any variations identified. Our secondary objective was to explore how any points of variation relate to national guidance. METHODS: This study entailed documentary analysis of commissioning policies that stipulated criteria for accessing eight elective musculoskeletal procedures. For each procedure, we retrieved policies held by regions with higher and lower rates of clinical activity relative to the national average. Policies were subjected to content and thematic analysis, using constant comparison techniques. Matrices and descriptive reports were used to compare themes across policies for each procedure and derive categories of variation that arose across two or more procedures. National guidance relating to each procedure were identified and scrutinised, to explore whether these provided context for explaining the policy variations. RESULTS: Thirty-five policy documents held by 14 geographic regions were included in the analysis. Policies either focused on a single procedure/treatment or covered several procedures/treatments in an all-encompassing document. All policies stipulated criteria that needed to be fulfilled prior to accessing treatment, but there were inconsistences in the evidence cited. Policies varied in recurring ways, with respect to specification of non-surgical treatments and management, requirements around time spent using non-surgical approaches, diagnostic requirements, requirements around symptom severity and disease progression, and use of language, in the form of terms and phrases (‘threshold modifiers’) which could open up or restrict access to care. National guidance was identified for seven of the procedures, but this guidance did not specify criteria for accessing the procedures in question, making direct comparisons with regional policies difficult. CONCLUSIONS: This, to our knowledge, is the first study to identify recurring ways in which policies for accessing treatment can vary within a single-payer system with universal coverage. The findings raise questions around whether formulation of commissioning policies should receive more central support to promote greater consistency – especially where evidence is uncertain, variable or lacking

Background: Promoting psychological well-being and preventing distress among pregnant women is an important public health goal. In addition to adversely impacting the mother’s health and well-being, psychological distress in pregnancy increases the risk of poor pregnancy outcomes, compromises infant socioemotional development and bonding, and heightens maternal and child vulnerability in the postpartum period. Mindfulness and compassion-based interventions show potential for prevention and early intervention for perinatal distress. As there is an established need for accessible, scalable, flexible, and low-cost interventions, there is increased interest in the delivery of these programs on the web. This project aims to pilot a three-arm randomized controlled trial (RCT) to determine the feasibility of a full-scale RCT comparing 2 web-based interventions (mindfulness vs loving-kindness and compassion) with a web-based active control condition (progressive muscle relaxation). Objective: The primary objective of this study is to assess the feasibility of an RCT protocol comparing the 3 conditions delivered on the web as a series of instructional materials and brief daily practices over a course of 8 weeks. The second objective is to explore the experiences of women in the different intervention conditions. The third objective is to estimate SD values for the outcome measures to inform the design of an adequately powered trial to determine the comparative efficacy of the different conditions. Methods: Pregnant women (n=75) participating in a longitudinal birth cohort study (the ORIGINS project) will be recruited to this study from 18 weeks of gestational age. We will assess the acceptability and feasibility of recruitment and retention strategies and the participants’ engagement and adherence to the interventions. We will also assess the experiences of women in each of the 3 intervention conditions by measuring weekly changes in their well-being and engagement with the program and by conducting a qualitative analysis of postprogram interviews. Results: This project was funded in September 2019 and received ethics approval on July 8, 2020. Enrollment to the study will commence in September 2020. Feasibility of a full-scale RCT will be assessed using ADePT (a process for decision making after pilot and feasibility trials) criteria. Conclusions: If the study is shown to be feasible, results will be used to inform future full-scale RCTs. Evidence for flexible, scalable, and low-cost interventions could inform population health strategies to promote well-being and reduce psychological distress among pregnant women

Perspective on Coarse-Graining, Cognitive Load, and Materials Simulation

The predictive capabilities of computational materials science today derive from overlapping advances in simulation tools, modeling techniques, and best practices. We outline this ecosystem of molecular simulations by explaining how important contributions in each of these areas have fed into each other. The combined output of these tools, techniques, and practices is the ability for researchers to advance understanding by efficiently combining simple models with powerful software. As specific examples, we show how the prediction of organic photovoltaic morphologies have improved by orders of magnitude over the last decade, and how the processing of reacting epoxy thermosets can now be investigated with million-particle models. We discuss these two materials systems and the training of materials simulators through the lens of cognitive load theory. For students, the broad view of ecosystem components should facilitate understanding how the key parts relate to each other first, followed by targeted exploration. In this way, the paper is organized in loose analogy to a coarse-grained model: The main components provide basic framing and accelerated sampling from which deeper research is better contextualized. For mentors, this paper is organized to provide a snapshot in time of the current simulation ecosystem and an on-ramp for simulation experts into the literature on pedagogical practice

Appetite and energy intake responses to acute energy deficits in females versus males

PURPOSE: To explore whether compensatory responses to acute energy deficits induced by exercise or diet differ by sex. METHODS: In experiment one, twelve healthy women completed three 9 h trials (control, exercise-induced (Ex-Def) and food restriction induced energy deficit (Food-Def)) with identical energy deficits being imposed in the Ex-Def (90 min run, ∼70% of VO2 max) and Food-Def trials. In experiment two, 10 men and 10 women completed two 7 h trials (control and exercise). Sixty min of running (∼70% of VO2 max) was performed at the beginning of the exercise trial. Participants rested throughout the remainder of the exercise trial and during the control trial. Appetite ratings, plasma concentrations of gut hormones and ad libitum energy intake were assessed during main trials. RESULTS: In experiment one, an energy deficit of ∼3500 kJ induced via food restriction increased appetite and food intake. These changes corresponded with heightened concentrations of plasma acylated ghrelin and lower peptide YY3-36. None of these compensatory responses were apparent when an equivalent energy deficit was induced by exercise. In experiment two, appetite ratings and plasma acylated ghrelin concentrations were lower in exercise than control but energy intake did not differ between trials. The appetite, acylated ghrelin and energy intake response to exercise did not differ between men and women. CONCLUSIONS: Women exhibit compensatory appetite, gut hormone and food intake responses to acute energy restriction but not in response to an acute bout of exercise. Additionally, men and women appear to exhibit similar acylated ghrelin and PYY3-36 responses to exercise-induced energy deficits. These findings advance understanding regarding the interaction between exercise and energy homeostasis in women

Canine babesiosis and tick activity monitored using companion animal electronic health records in the UK

Recent publications highlighting autochthonous Babesia canis infection in dogs from Essex that have not travelled outside the UK are a powerful reminder of the potential for pathogen emergence in new populations. Here the authors use electronic health data collected from two diagnostic laboratories and a network of 392 veterinary premises to describe canine Babesia cases and levels of Babesia concern from January 2015 to March 2016, and the activity of ticks during December 2015–March 2016. In most areas of the UK, Babesia diagnosis in this population was rare and sporadic. In addition, there was a clear focus of Babesia cases in the affected area in Essex. Until February 2016, analysis of health records indicated only sporadic interest in Babesia largely in animals coming from overseas. Following media coverage in March 2016, there was a spike in owner concern that was geographically dispersed beyond the at-risk area. Tick activity (identified as ticks being removed from animals in veterinary consultations) was consistent but low during the period preceding the infections (<5 ticks/10,000 consultations), but increased in March. This highlights the use of electronic health data to describe rapidly evolving risk and concern that follows the emergence of a pathogen

Association of CREBRF variants with obesity and diabetes in Pacific Islanders from Guam and Saipan

Aims hypothesis Variants in CREBRF (rs12513649 and rs373863828) have been strongly associated with increased BMI and decreased risk of type 2 diabetes in Polynesian populations; the A allele at rs373863828 is common in Polynesians but rare in most other global populations. The aim of the present study was to assess the association of CREBRF variants with obesity and diabetes in Pacific Islander (largely Marianas and Micronesian) populations from Guam and Saipan. Methods CREBRF rs12513649 and rs373863828 were genotyped in 2022 participants in a community-based cross-sectional study designed to identify determinants of diabetes and end-stage renal disease (ESRD). Associations were analysed with adjustment for age, sex, ESRD and the first four genetic principal components from a genome-wide association study (to account for population stratification); a genomic control procedure was used to account for residual stratification. Results The G allele at rs12513649 had an overall frequency of 7.7%, which varied from 2.2% to 20.7% across different Marianas and Micronesian populations; overall frequency of the A allele at rs373863828 was 4.2% (range: 1.1–5.4%). The G allele at rs12513649 was associated with higher BMI (β=1.55 kg/m2 per copy; p=0.0026) as was the A allele at rs373863828 (β=1.48 kg/m2, p=0.033). The same alleles were associated with lower risk of diabetes (OR per copy: 0.63 [p=0.0063] and 0.49 [p=0.0022], respectively). Meta-analyses combining the current results with previous results in Polynesians showed a strong association between the A allele at rs373863828 and BMI (β=1.38 kg/m2;p=2.5×l0−29) and diabetes (OR=0.65, p=1.5×l0−13). Conclusions interpretation These results confirm the associations of CREBRF variants with higher BMI and lower risk of diabetes and, importantly, they suggest that these variants contribute to the risk of obesity and diabetes in Oceanic populations
