Playing it safe : the influence of neighbourhood safety on children's physical activity − A review

Compared with previous generations, children spend less time playing outdoors and have lower participation rates in active transport. Many studies have identified lack of neighbourhood safety as a potential barrier to children's physical activity. This review describes concerns regarding ‘stranger danger’ and road safety, and discusses empirical studies that examine associations between neighbourhood safety and physical activity among youth. Variability of perceptions of safety between parents and youth are examined; ‘social traps’ are identified; and physical/social environmental interventions aimed at improving neighbourhood safety are discussed. A research agenda is suggested for further study of perceived and objective measures of neighbourhood safety and their associations with children's physical activity.

Gregory Palamas on the relationship between philosophy and theology

The relationship between philosophy and theology has rarely been a harmonious and fruitful one. The two disciplines are often segmented into mutually exclusive compartments. On the one hand, philosophers, particularly contemporary philosophers working within the Anglo-American analytic tradition, widely agree that the claims made by theologians – such as the claim that there is a God and that God is a trinity of persons – are meaningless, or false, or irrational, or unsupported by evidence, or in some other way epistemically below par. On the other hand, it is not unusual to find theologians following in the footsteps of writers such as Tertullian, Kierkegaard and Barth in arguing that, when it comes to theology, faith suffices and reason merely perverts.

The philosophy-theology dispute was no stranger to fourteenth-century Byzantium, particularly in the writings of the most prominent spiritual and intellectual figure of this period, viz., Gregory Palamas (c.1296-1359). In his debates with Barlaam of Calabria (c.1290-1348), Gregory Akindynos (c.1300-1348) and Nikephoros Gregoras (c.1290-c.1358), the issue of the appropriateness of employing philosophical terms and modes of reasoning in theology occupied a central place.[1] But before looking at how Palamas tackled this issue, it will be helpful, firstly, to briefly outline how the Christian world (especially in the East) prior to Palamas tended to see the relationship between secular learning (including philosophy) and theology; and secondly, to ascertain what exactly was Palamas’ conception of philosophy.

Does moral cleansing moderate the effect of evolutionary altruism on helping intention? An exploratory study

There is strong evidence for social evolutionary motivations for helping (e.g., reciprocal altruism) and also growing support for the influence of the social cognitive theory of moral cleansing on prosociality. Where the former motivation is interpersonal, the latter is intrapersonal. This experimental study hypothesized that, in addition to main effects of evolutionary altruism and moral cleansing on helping intention, an interaction would occur between these theoretical motivations. Using three situational helping scenarios as dependent measures, the effect of participants’ morally-valenced recalled behavior (moral/immoral/achievement/failure) and the effect of their social proximity to a helping target (cousin/colleague/stranger) on helping intention was determined. Overall, 616 Australian participants (90.1% female) completed the online experiment. Two-way ANOVA demonstrated a consistent main effect of social proximity on helping intention across all three helping scenarios, supporting evolutionary social psychological explanations for helping. However, instead of moral self-regulation effects, moral identity consistency effects were induced by the moral behavior recall manipulation. A main effect of behaviour recall on helping intention occurred, with moral recall increasing helping intention. The problem of theoretical ambiguity regarding moral identity consistency and moral self-regulation is discussed, as is the useful role of null result publications in informing effective experimental design.

Neighborhood perceptions moderate the association between the family environment and children's objectively assessed physical activity

This study aimed to investigate whether parents' perceptions of the neighborhood environment moderate associations between the family environment and children's moderate- to vigorous-intensity physical activity (MVPA) outside of school hours. In total, 929 parents of 10-12 year-old children completed a questionnaire concerning the family environment, MVPA levels, and the neighborhood environment. Children wore an Actigraph (AM7164-2.2C) accelerometer. Compared with neighborhood environment factors, the family environment was more frequently associated with children's MVPA. Parental MVPA was positively associated with children's MVPA, but only among children whose parents reported a high presence of sporting venues. Having more restrictive physical activity rules was negatively associated with children's weekday MVPA in neighborhoods with high perceived stranger danger.
