Ethical trust and social moral norms simulation : a bio-inspired agent-based modelling approach

The understanding of the micro-macro link is an urgent need in the study of social systems. The complex adaptive nature of social systems adds to the challenges of understanding social interactions and system feedback and presents substantial scope and potential for extending the frontiers of computer-based research tools such as simulations and agent-based technologies. In this project, we seek to understand key research questions concerning the interplay of ethical trust at the individual level and the development of collective social moral norms as representative sample of the bigger micro-macro link of social systems. We outline our computational model of ethical trust (CMET) informed by research findings from trust, machine ethics and neural science. Guided by the CMET architecture, we discuss key implementation ideas for the simulations of ethical trust and social moral norms.

Interplay of ethical trust and social moral norms : environment modelling and computational mechanisms in agent-based social simulation

In many agent-based models theoretical and computational mechanisms are needed for model abstraction and design. However, it can be challenging to arrive at the appropriate mechanisms and models. This research on the interplay of ethical trust and social moral norms addresses that challenge via an analytical framework on the spread of moral norms, the modelling of social environment and the selection of spread mechanisms as applied to agent-based social simulation. We describe the mechanism alignment mapping, two forms of interaction modelling between the social environment and agents, and the results obtained from the simulation of our computational model. These results provide an insight into how the agent-based paradigm can be applied as a technique of investigation for normative moral processes in computational social sciences.

A music and health perspective on music's perceived 'goodness'

In this paper consideration is given to aspects of social and professional music use premised from a “music as health” perspective. This critical exploration is intended to reveal values about music participation and music listening, with consideration of the way music is constructed as a contributor to social gains within music as health application. The frequently encountered expectation that music participation and music listening are innately good and “helpful” is examined. A range of projects are described and examined with reference to the theme of music's “commodified goodness” or what has elsewhere been termed, the ubiquitous “goodness of music” (Edwards, 2008b).

Reliability of the pictorial scale of perceived movement skill competence in 2 diverse samples of young children

The purpose was to determine the reliability of an instrument designed to assess young children's perceived movement skill competence in two diverse samples.

Associations between young children's perceived and actual ball skill competence and physical activity

Objectives: The relationship between actual and perceived object control competence (ball skills) and the contribution to young children’s physical activity is not known.
Design: Cross sectional study.
Methods: The Test Gross Motor Development-2 assessed actual object control competence and a modified version of the Pictorial Scale of Perceived Competence and Social Acceptance for Young Children assessed perceived object control competence. Moderate- to vigorous-intensity physical activity was measured via accelerometry. Three mixed regression models were performed: (i) object control competence as the predictor and the outcome as perceived object control, (ii) perceived object control competence as the predictor and the outcome moderate to vigorous physical activity and (iii) actual object control as the predictor and the outcome moderate to vigorous physical activity. Models adjusted for school clustering, monitor wear time, sex and age. Interactions between respective predictor variables and sex were performed if warranted. A total of 102 children (56% boys, 44% girls) aged 4–8 years (M 6.3, SD 0.92) completed assessments.
Results: Girls had lower perceived and actual object control competence and were less active than boys. Actual object control competence was positively associated with perceived object control competence (B = 0.11, t(96) = 2.25, p < 0.001, p = 0.027) and this relationship did not differ by sex (p = 0.449); however, neither actual (p = 0.092) nor perceived object control competence (p = 0.827) were associated with moderate to vigorous physical activity.
Discussion: Young children’s perceived ball skill abilities appear to relate to actual competence; however, these measures were not associated with physical activity. In older children, object control skill is associated with physical activity so targeting young children’s object control skills is an intervention priority.

Face validity and reliability of a pictorial instrument for assessing fundamental movement skill perceived competence in young children

A Q methodology study of stakeholders' views about accountability for promoting healthy food environments in England through the responsibility deal food network

In March 2011, the United Kingdom's (UK's) Government launched five Public Health Responsibility Deal Networks to address public health priorities. The Networks used voluntary partnerships to influence peoples' choice architecture to move them toward healthier behaviors. The purpose of this research was to conduct an exploratory study of diverse stakeholders' perspectives about perceived responsibility and accountability expectations to improve food environments in England through the Food Network partnerships. A purposive sample of policy elites (n=31) from government, academia, food industry and non-government organizations sorted 48 statements related to improving food environments in England. Statements were grounded in three theoretical perspectives (i.e., legitimacy, nudge and public health law). PQMethod 2.33 statistical software program used factor analysis to identify viewpoints based on intra-individual differences for how participants sorted statements. The results revealed three distinct viewpoints, which explained 64% of the variance for 31 participants, and emphasized different expectations about responsibility. The food environment protectors (n=17) underscored government responsibility to address unhealthy food environments if voluntary partnerships are ineffective; the partnership pioneers (n=12) recognized government-industry partnerships as legitimate and necessary to address unhealthy food environments; and the commercial market defenders (n=1) emphasized individual responsibility for food choices and rejected government intervention to improve food environments. Consensus issues included: protecting children's right to health; food industry practices that can and should be changed; government working with industry on product reformulation; and building consumer support for economically viable healthy products. Contentious issues were: inadequacy of accountability structures and government inaction to regulate food marketing practices targeting children. We conclude that understanding different viewpoints is a step toward building mutual trust to strengthen accountability structures that may help stakeholders navigate ideologically contentious issues to promote healthy food environments in England.

Associations between the perceived environment and physical activity among adults aged 55-65 years : does urban-rural area of residence matter?

This study aimed to determine whether associations between the perceived environment and physical activity are moderated by urban-rural status among midolder aged adults. Environmental (safety, aesthetics, physical activity environment) and physical activity (total, leisure, transport) data from 3,888 adults (55 to 65 years) from urban and rural areas of Victoria, Australia, were analyzed. Multinomial logistic regression examined interactions between urban-rural status and environments in associations with physical activity. Significant (P < .05) interactions were evident and indicated positive associations only among older rural adults for both safety and aesthetics with total and transport physical activity (e.g., rural adults reporting higher safety were 91% to 118% more likely to have higher activity than rural adults reporting low safety). In contrast, the physical activity environment was positively associated with leisure activity among only urban adults. Findings suggest that some tailoring of physical activity promotion strategies targeting the environment may be required for urban and rural midolder aged adults.
