Change,Difference, and Orthodox Truthmaker Theory

Call the thesis that, possibly, there are two times, t₁ and t₂, such that everything that exists at t₂ also exists at t₁, but some things that exist at t₁ do not exist at t₂ Temporal Change. Call the thesis that, possibly, there are two worlds, w and v, such that everything that exists at v also exists at w, but some things that exist at w do not exist at v Modal Difference. I argue that if either Temporal Change or Modal Difference is true, then Orthodox Truthmaker Theory—the theory that every truth requires a necessitating truthmaker—is false.     

The cost of truthmaker maximalism

According to truthmaker theory, particular truths are true in virtue of the existence of particular entities. Truthmaker maximalism holds that this is so for all truths. Negative existential and other ‘negative’ truths threaten the position. Despite this, maximalism is an appealing thesis for truthmaker theorists. This motivates interest in parsimonious maximalist theories, which do not posit extra entities for truthmaker duty. Such theories have been offered by David Lewis and Gideon Rosen, Ross Cameron, and Jonathan Schaffer. However, it will be argued here that these theories cannot be sustained, and hence maximalism comes with a serious ontological cost. Neither Armstrong's invocation of totality facts nor the Martin-Kukso line on absences can meet this cost satisfactorily. I'll claim that negative facts are the best (and perhaps only) way out of the problem for the truthmaker maximalist.     

Beyond the twee: Thuy’s practical expression of living the Mercy Education Value of hospitality

This article utilises hermeneutic phenomenology as a theoretical framework for reflecting upon and interpreting the Mercy Education Value of hospitality. It describes an incident involving the author’s encounter with a member of staff upon his new appointment in a Catholic secondary college formed in the Mercy Tradition. Through this article, the possibilities opened by such an encounter for hermeneutic phenomenology are explored using van Manen’s lifeworld existentials as guides to reflection upon the described incident. The four lifeworld existentials are lived space (spatiality), lived body (corporeality), lived time (temporality) and lived other (relationality). In using these as guides to reflection, it is argued that some insights into the Mercy value of hospitality may be gleaned, namely that to be Mercy involves: (1) exceeding the carefully and socially programmed how are you – fine exchange; (2) an encounter with the other – the stranger – in whom is to be found the person of Jesus Christ, in which both participants are transformed; and (3) taking a risk – pushing boundaries so as to enter into relationship with the other.     

A meta‐analysis of serotonin metabolite 5‐HIAA and antisocial behavior

During the past 25 years, researchers have examined the relationship between neurochemical variables and antisocial behavior in human adults, but none has been studied more intensely than the serotonin metabolite 5‐hydroxyindoleacetic acid (5‐HIAA). The goal of the current study was to employ meta‐analytic procedures to quantitatively evaluate selected evidence on the relationship between 5‐HIAA and antisocial behavior. It was expected that antisocial groups would show reduced cerebrospinal fluid 5‐HIAA compared with non–antisocial groups. This study also aimed to assess moderators that could influence the relationship between 5‐HIAA and antisociality. An electronic search and strict inclusion criteria identified 20 reports used in this meta‐analysis. Results showed a significant overall mean effect size (ES = –.45, P < .05) in the direction of lowered 5‐HIAA in antisocial vs. non–antisocial groups. A significant moderating effect for age indicated that groups comprised of antisocial individuals younger than 30 years exhibited larger negative effect sizes (ES = –1.37, P < .05) than groups with older subjects (ES = –.31, P < .05). There were no moderating effects for gender, target of violence, history of suicide, and alcoholism. Age effects may help explain age‐related declines in crime. The fact that effects did not differ based on other moderating variables supports models of reduced serotonin in antisocial individuals, regardless of type of crime or psychiatric problems. Aggr.

Less Adaptive or More Maladaptive? A Meta‐analytic Investigation of Procrastination and Coping

Despite the theoretical and empirical accounts of trait procrastination as reflecting avoidance of aversive tasks as a means of mood repair, research documenting its links to coping is scarce and inconsistent. There is also little if any research to date examining whether coping strategies might explain the procrastination–stress relationship. The current research aimed to address these issues by integrating current research on procrastination and coping with our own data into a first meta‐analysis of the associations of procrastination with adaptive and maladaptive coping and then testing the potential role of coping for understanding the procrastination–stress relationship. In Study 1, a literature search yielded five published papers and three theses, which were supplemented by seven unpublished data sets comprising 15 samples (N = 4357). Meta‐analyses revealed that procrastination was positively associated with maladaptive coping (average r = .31) and negatively associated with adaptive coping (average r = ?.24). In Study 2, a meta‐analysis of the indirect effects through coping across four samples revealed that the average indirect effects for maladaptive but not adaptive coping explained the link between procrastination and stress. These findings expand the nomological network of procrastination and highlight the role of maladaptive coping for understanding procrastinators' stress.
