Oh the humanity! Humanity-esteem and its social importance

Past research has examined the consequences of a favorable personal identity (i.e., personal self-esteem) and social identity (i.e., collective self-esteem), but has neglected the consequences of a favorable human identity (i.e., humanity-esteem). Two studies examined individual differences in humanity-esteem using a new measure of this construct, the Humanity-Esteem Scale. Results indicated that the measure is reliable, taps affective and cognitive reactions to humanity, and possesses strong convergent and discriminant validity. Furthermore, a third study utilized a manipulation of humanity-esteem to examine its effect on group differentiation. The results supported the notion that low humanity-esteem increases group differentiation. Thus, humanity-esteem is an important novel construct for understanding how humans regard and relate to one another.     

Legal Bans on Pro‐Suicide Web Sites: An Early Retrospective from Australia

There are worldwide concerns that pro‐suicide web sites may trigger suicidal behaviors among vulnerable individuals. In 2006, A ustralia became the first country to criminalize such sites, sparking heated debate. Concerns were expressed that the law casts the criminal net too widely; inappropriately interferes with the autonomy of those who wish to die; and has jurisdictional limitations, with off‐shore web sites remaining largely immune. Conversely, proponents point out that the law may limit access to domestic pro‐suicide web sites, raise awareness of Internet‐related suicide, mobilize community efforts to combat it, and serve as a powerful expression of societal norms about the promotion of suicidal behavior.     

The Axes of Debt: A Preface to Three Essays

This is a preface to three essays on different aspects of ontological and economic debt as themes in religious ethics. It frames their contribution by arguing that debt is central to traditions of philosophical and religious ethics yet is woefully neglected as a thematic problem and problematic in contemporary iterations of these traditions. In order to situate debt as a central moral concern, it is argued that any consideration of debt must wrestle with how debt exists on two axes. One is the axis of ontological and economic debt. The other is the axis of debt as an expression of mutuality and debt as a mode of domination. These axes generate deep ambiguities regarding the moral status of debt. But contemporary religious and philosophical ethics struggles to articulate, let alone address, this ambiguity due to being wedded to modern conceptions of the autonomous subject. The essay closes by setting out the themes of the three essays, the connections between them, and how they can be a catalyst for further reflection on this vital but under‐researched topic.     

No Identity Without an Entity

Peter Geach's puzzle of intentional identity is to explain how the claim ‘Hob thinks a witch has blighted Bob's mare, and Nob wonders whether she (the same witch) killed Cob's sow’ is compatible with there being no such witch. I clarify the puzzle and reduce it to the familiar problem of negative existentials. That problem is a paradox of representations that seem to include denials of commitment (implicitly, here), to carry commitment to what they deny commitment to, and to be true. The best proposed solutions can be understood through this paradox; I evaluate them, and defend a new solution.     

The diamond ratio: A visual indicator of the extent of heterogeneity in meta-analysis

The result of a meta-analysis is conventionally pictured in the forest plot as a diamond, whose length is the 95% confidence interval (CI) for the summary measure of interest. The Diamond Ratio (DR) is the ratio of the length of the diamond given by a random effects meta-analysis to that given by a fixed effect meta-analysis. The DR is a simple visual indicator of the amount of change caused by moving from a fixed-effect to a random-effects meta-analysis. Increasing values of DR greater than 1.0 indicate increasing heterogeneity relative to the effect variances. We investigate the properties of the DR, and its relationship to four conventional but more complex measures of heterogeneity. We propose for the first time a CI on the DR, and show that it performs well in terms of coverage. We provide example code to calculate the DR and its CI, and to show these in a forest plot. We conclude that the DR is a useful indicator that can assist students and researchers to understand heterogeneity, and to appreciate its extent in particular cases.     

A general approach to causal mediation analysis

Traditionally in the social sciences, causal mediation analysis has been formulated, understood, and implemented within the framework of linear structural equation models. We argue and demonstrate that this is problematic for 3 reasons: the lack of a general definition of causal mediation effects independent of a particular statistical model, the inability to specify the key identification assumption, and the difficulty of extending the framework to nonlinear models. In this article, we propose an alternative approach that overcomes these limitations. Our approach is general because it offers the definition, identification, estimation, and sensitivity analysis of causal mediation effects without reference to any specific statistical model. Further, our approach explicitly links these 4 elements closely together within a single framework. As a result, the proposed framework can accommodate linear and nonlinear relationships, parametric and nonparametric models, continuous and discrete mediators, and various types of outcome variables. The general definition and identification result also allow us to develop sensitivity analysis in the context of commonly used models, which enables applied researchers to formally assess the robustness of their empirical conclusions to violations of the key assumption. We illustrate our approach by applying it to the Job Search Intervention Study. We also offer easy-to-use software that implements all our proposed methods.
