Processing Messages for Reconciliation: What Produces Changes in Attitudes Instead of Resistance?

Conflicts between groups harm positive intergroup relations. Parties to intergroup conflict have developed a variety of methods for fostering reconciliation following conflicts. Out of these different mechanisms, intergroup apology is the most studied empirically but there are still a number of gaps in this research. To address these gaps, my research brought together intergroup apology research, attitude change and persuasion research, and findings on the role of group identification. In this research I assumed that apologies and other efforts for reconciliation function as persuasive messages for intergroup reconciliation. The research assessed the way in which participants from both victim and perpetrator groups cognitively process these messages. According to persuasion research, if an individual is inoculated to a persuasive message prior to hearing it, that person will be more likely to resist attitude change. Studies 1, 2, and 3 were all 2 (victim vs. perpetrator group member) x 2 (inoculation vs. no inoculation) factorial designs with a continuous moderator, with researcher race (person of color vs. White) also examined in Study 1. The context of Study 1 was an interracial injustice committed against African-Americans by the United States government. The context of Study 2 was the long history of interracial violations committed against the largest indigenous group in Chile by the dominant group and government. Finally, the context of Study 3 was the conflict between the political Left and Right in Chile during the dictatorship of Augusto Pinochet. Overall, I found that the way participants processed the messages was related to the outcome variables. Study 1 revealed expected effects of inoculation and similar effects of researcher race. Studies 2 and 3 demonstrated group differences largely in line with positions on each side of the conflicts in Chile. The implication, limitations, and future directions of this research were discussed

Investigating the Toxicity and Accumulation of 2,4-Dichlorophenoxyacetic Acid (2,4-D) and Glyphosate in Eisenia fetida

Glyphosate, the main ingredient in Roundup®, is the most widely used herbicide in the world. It is also used in combination with another effective herbicide, 2,4-D, in the formulation called Enlist Duo®. The EPA approved the use of Enlist Duo® on certain crops including those genetically modified to be resistant to both herbicides. The predicted significant increase in the use of these herbicides raised concerns from the general public because both compounds have been classified as possibly or probably carcinogenic. Since herbicides are applied directly to vegetation, the safety of organisms that come in contact with the herbicides is at risk. In this toxicity study, the responses of earthworms exposed to various concentrations of 2,4-D, glyphosate, or both were investigated. Results of direct contact studies show severe effects of 2,4-D on worms, including death. Despite seeing ill effects in direct contact trials, we saw no significant difference in the mortality rates, reproductive health, and weight of the earthworms treated via ingestion of contaminated soil or vegetation. As earthworms constitute a food source for other organisms, bioaccumulation is possible. An HPLC method to detect herbicide uptake in earthworm tissues was also developed. These methods were suitable for analyzing worms obtained from soil and plants treated with 2,4-D, glyphosate, or both. HPLC analysis showed uptake of both 2,4-D and glyphosate but no evidence indicating that the presence of 2,4-D changed the uptake of glyphosate

'Personalised evidence' for personalised healthcare: integration of a clinical librarian into mental health services – a feasibility study

Aims and method To evaluate the feasibility of integrating a clinical librarian (CL) within four mental health teams. A CL was attached to three clinical teams and the Trustwide Psychology Research and Clinical Governance Structure for 12 months. Requests for evidence syntheses were recorded. The perceived impact of individual evidence summaries on staff activities was evaluated using a brief online questionnaire. Results Overall, 82 requests for evidence summaries were received: 50% related to evidence for individual patient care, 23% to generic clinical issues and 27% were on management/corporate topics. In the questionnaires 105 participants indicated that the most common impact on their practice was advice given to colleagues (51 respondents), closely followed by the evidence summaries stimulating new ideas for patient care or treatment (50 respondents). Clinical implications The integration of a CL into clinical and corporate teams is feasible and perceived as having an impact on staff activities. A CL may be able to collate ‘personalised evidence’ which may enhance individualised healthcare. In some cases the usual concept of a hierarchy of evidence may not easily apply, with case reports providing guidance which may be more applicable than population-based studies

Collagen Based Multicomponent Interpenetrating Networks as Promising Scaffolds for 3D Culture of Human Neural Stem Cells, Human Astrocytes, and Human Microglia

This work describes for the first time the fabrication and characterization of multicomponent interpenetrating networks composed of collagen I, hyaluronic acid, and poly(ethylene glycol) diacrylate for the 3D culture of human neural stem cells, astrocytes, and microglia. The chemical composition of the scaffolds can be modulated while maintaining values of complex moduli within the range of the mechanical performance of brain tissue (∼6.9 kPa) and having cell viability exceeding 84%. The developed scaffolds are a promising new family of biomaterials that can potentially serve as 3D in vitro models for studying the physiology and physiopathology of the central nervous system

Proficiency deficiency: mastery of fundamental movement skills and skill components in overweight and obese children

The purpose of this observational study was to compare the mastery of 12 fundamental movement skills (FMS) and skill components between a treatment-seeking sample of overweight/obese children and a reference sample from the United States. Mastery of six locomotor and six object-control skills (24 components in each subdomain) were video-assessed by one assessor using the test of gross motor development-2 (TGMD-2). The 153 overweight/obese children (mean ± s.d. age = 8.3 ± 1.1 years, BMI z-score = 2.78 ± 0.69, 58% girls, 77% obese) were categorized into age groups (for the underhand roll and strike: 7–8 years and 9–10 years; all other FMS: 6–7 years and 8–10 years) and mastery prevalence rates were compared with representative US data (N = 876) using χ2 analysis. For all 12 skills in all age groups, the prevalence of mastery was lower among overweight/obese children compared with the reference sample (all P < 0.05). This was consistent for 18 locomotor and upto 21 object-control skill components (all P < 0.05). Differences were largest for the run, slide, hop, dribble, and kick. Specific movement patterns that could be targeted for improvement include positioning of the body and feet, the control or release of an object at an optimal position, and better use of the arms to maintain effective force production during the performance of FMS. Physical activity programs designed for overweight and obese children may need to address deficiencies in FMS proficiency to foster the movement capabilities required for participation in health-enhancing physical activity

Gender disparities in colloquium speakers at top universities

Colloquium talks at prestigious universities both create and reflect academic researchers' reputations. Gender disparities in colloquium talks can arise through a variety of mechanisms. The current study examines gender differences in colloquium speakers at 50 prestigious US colleges and universities in 2013-2014. Using archival data, we analyzed 3,652 talks in six academic disciplines. Men were more likely than women to be colloquium speakers even after controlling for the gender and rank of the available speakers. Eliminating alternative explanations (e.g., women declining invitations more often than men), our follow-up data revealed that female and male faculty at top universities reported no differences in the extent to which they (i) valued and (ii) turned down speaking engagements. Additional data revealed that the presence of women as colloquium chairs (and potentially on colloquium committees) increased the likelihood of women appearing as colloquium speakers. Our data suggest that those who invite and schedule speakers serve as gender gatekeepers with the power to create or reduce gender differences in academic reputations

Kin recognition in a clonal fish, Poecilia formosa

Relatedness strongly influences social behaviors in a wide variety of species. For most species, the highest typical degree of relatedness is between full siblings with 50% shared genes. However, this is poorly understood in species with unusually high relatedness between individuals: clonal organisms. Although there has been some investigation into clonal invertebrates and yeast, nothing is known about kin selection in clonal vertebrates. We show that a clonal fish, the Amazon molly (Poecilia formosa), can distinguish between different clonal lineages, associating with genetically identical, sister clones, and use multiple sensory modalities. Also, they scale their aggressive behaviors according to the relatedness to other females: they are more aggressive to non-related clones. Our results demonstrate that even in species with very small genetic differences between individuals, kin recognition can be adaptive. Their discriminatory abilities and regulation of costly behaviors provides a powerful example of natural selection in species with limited genetic diversity.Funding was provided by an Adams Memorial Scholarship, Robberson Research Grant, Graduate Student Senate Research Grant, L.G.

Heart rate, energy expenditure, and affective responses from children participating in trampoline park sessions compared with traditional extra-curricular sports clubs

BACKGROUND: Lack of physical activity (PA) is becoming an issue in younger populations. Trampoline parks are newly popular environments for PA yet research on their use is scarce. Thus the present study compared heart rate, energy expenditure, and affective responses in children participating in trampoline park sessions compared with extracurricular sports clubs. METHODS: Children (aged 6-11 years; N.=16 females, N.=10 males) participated in 3 trampoline park sessions and 3 extracurricular sports club sessions lasting ~45 minutes over 3 weeks. Heart rate, energy expenditure, and affective responses through the circumplex model, were measured. RESULTS: Both conditions elicited moderate-vigorous PA. Average heart rate (mean difference [95%CIs]=27.6 fc [23.5 to 31.8]), peak heart rate (mean difference [95%CIs]=24.2 fc [20.8 to 27.6]) and energy expenditure (mean difference [95%CIs]=3.2 kcals.min-1 [2.7 to 3.6]) were all significantly higher for the trampoline sessions. Affective responses for both conditions elicited feelings of “excitement.” CONCLUSIONS: Both extracurricular sports clubs and trampoline park activities provide moderate-vigorous PA, though the latter may result in higher heart rate and energy expenditure responses. Both however produce similar positive affective responses. As such, both could be valuable options for PA opportunities for children

The National ReferAll Database: An Open Dataset of Exercise Referral Schemes Across the UK

In 2014, The National Institute for Health and Care Excellence (NICE) called for the development of a system to collate local data on exercise referral schemes (ERS). This database would be used to facilitate continued evaluation of ERS. The use of health databases can spur scientific investigation and the generation of evidence regarding healthcare practice. NICE’s recommendation has not yet been met by public health bodies. Through collaboration between ukactive, ReferAll, a specialist in software solutions for exercise referral, and the National Centre for Sport and Exercise Medicine, which has its research hub at the Advanced Wellbeing Research Centre, in Sheffield, data has been collated from multiple UK-based ERS to generate one of the largest databases of its kind. This database moves the research community towards meeting NICEs recommendation. This paper describes the formation and open sharing of The National ReferAll Database, data-cleaning processes, and its structure, including outcome measures. Collating data from 123 ERSs on 39,283 individuals, a database has been created containing both scheme and referral level characteristics in addition to outcome measures over time. The National ReferAll Database is openly available for researchers to interrogate. The National ReferAll Database represents a potentially valuable resource for the wider research community, as well as policy makers and practitioners in this area, which will facilitate a better understanding of ERS and other physical-activity-related social prescribing pathways to help inform public health policy and practice
