Does Weather Actually Affect Tipping? An Empirical Analysis of Time‐Series Data1

Prior literature has found evidence that pleasant weather (namely, sunshine) leads to higher tipping rates, presumably because it improves the moods of either servers or patrons. However, studies examining the relationship between pleasant weather and tipping behavior have involved relatively small samples of participants and daily observations. In addition, only one such study ( Cunningham, 1979 ) used actual weather data to examine this relationship. We address these shortcomings by testing empirically the weather–tipping relationship on 2 years of actual sales data from a busy restaurant. We found no statistically significant relationship between sunshine and tipping. Tipping appears to be better explained as an institutional standard or norm, rather than as a prosocial behavior that can be modulated by weather‐induced changes in mood.     

Asymmetry in the detection of shapes from shading in infants1

Abstract: We investigated 3‐ and 4‐month‐old infants’ sensitivity to differences defined by shading using a paired‐comparison familiarity/novelty preference procedure. Infants were familiarized with a pair of displays consisting of homogeneous shaded disks, and then were tested with two displays: the familiar display and a novel one containing shaded disks with reversed polarity (defined as the target). Experiment 1 examined two assumptions on discerning shapes from shading in infants by manipulating the orientations in the shading gradient of stimuli. When the orientation of the shading gradient was vertical, 4‐month‐old infants looked at the novel display for a longer time during the test trial. However, they failed to detect differences when the orientation of shading gradients was horizontal. Three‐month‐old infants did not detect differences in either orientation of the shading gradient. Experiment 2 examined asymmetry in the detection of convex versus concave shapes. Four‐month‐old infants failed to detect the target when the orientation of the shading grating was vertical and the target was convex. Taken with the results of Experiment 1, concave shapes were much easier to detect than convex shapes for 4‐month‐olds. This asymmetry suggests that 4‐month‐old infants process shading information in the same manner as adults.     

SOCIAL CAPITAL & FAITH‐BASED ORGANISATIONS

This year is the twentieth anniversary of the germinal report ‘Faith in the City’ which first drew attention to the concerns of religious agencies whose remit is to tackle growing multiple deprivation in the UK. Since then, the role of faith‐based organisations (FBOs) as mediators of welfare provision, urban regeneration and community development has attracted little attention from sociologists despite claims that such roles are becoming increasingly important. Successive UK governments have highlighted the potential of religious congregations in enhancing social capital and promoting social cohesion. The seminal work of Greg Smith (University of East London) emphasises this theme while other sociological literature in this area (mainly American, e.g., Putnam) argues that FBOs in the community provide a degree of social support and relationship structures that accumulate as social capital resources. This discussion paper is an attempt to open up the debate on the ways in which FBOs can develop and enhance the social capital value of local community groups.     

The Non-conceptual Content of Perceptual Experience: Situation Dependence and Fineness of Grain

I begin by examining a recent debate between John McDowell and Christopher Peacocke over whether the content of perceptual experience is non-conceptual. Although I am sympathetic to Peacocke's claim that perceptual content is non-conceptual, I suggest a number of ways in which his arguments fail to make that case. This failure stems from an over-emphasis on the "fine-grainedness" of perceptual content -a feature that is relatively unimportant to its non-conceptual structure. I go on to describe two other features of perceptual experience that are more likely to be relevant to the claim that perceptual content is non-conceptual. These features are 1) the dependence of a perceived object on the perceptual context in which it is perceived and 2) the dependence of a perceived property on the object it is perceived to be a property of.
