A Note on Neat Reducts

SC, CA, QA and QEA denote the class of Pinter’s substitution algebras, Tarski’s cylindric algebras, Halmos’ quasi-polyadic and quasi-polyadic equality algebras, respectively. Let . and . We show that the class of n dimensional neat reducts of algebras in K _m is not elementary. This solves a problem in [2]. Also our result generalizes results proved in [1] and [2].

On the construction of fuzzy preference structures

In this paper, we analyse the generalization of the classical method of the construction of a preference structure from a reflexive binary relation to the case of fuzzy binary relations. According to our approach, there are two interesting fuzzy preference structures we can construct from a given reflexive fuzzy binary relation. These two fuzzy preference structures correspond to the two extreme solutions of the system of functional equations in the method of Fodor and Roubens. We also prove that only one of two fuzzy preference structures allows its fuzzy relation of strict preference to be transitive with respect to the φ-transform of the Lukasiewicz t-norm when the reflexive fuzzy relation it is constructed from is also transitive with respect to the same t-norm. © 1998 John Wiley & Sons, Ltd.     

Rationality and Future Discounting

The best justification of time-discounting is roughly that it is rational to care less about your more distant future because there is less of you around to have it. I argue that the standard version of this argument, which treats both psychological continuity and psychological connectedness as reasons to care about your future, can only rationalize an irrational—because exploitable—form of future discounting.

Short-term clinical risk assessment and management: Comparing the Brockville Risk Checklist and Hamilton Anatomy of Risk Management

The current article aims to examine the performance of two brief, dynamic risk measures – the Brockville Risk Checklist (BRC4) and one of two versions of the Hamilton Anatomy of Risk Management [HARM-FV and electronic HARM-FV (eHARM-FV)] – scored at regular clinical case conferences for forensic psychiatric patients in two different settings. The eHARM represents a first-in-class dynamic risk assessment tool using data analytics. Two studies are presented from two forensic psychiatric hospitals in Ontario, Canada. The first study compared the HARM-FV, scored by trained research staff, with the BRC4, scored concurrently by clinical teams, on 36 forensic inpatients. In the second study, trained research staff scored both the BRC4 and the eHARM-FV on 55 forensic inpatients. Both studies demonstrated that the BRC4 and both HARM-FV tools were moderately and positively correlated with each other, with higher agreement for similar domains and items. In both samples, the risk measures performed better at identifying individuals who engaged in repeated or more serious problematic behavior. The HARM-FV and eHARM-FV produced higher area under the curve values for subsequent behavior compared with the BRC4. All three tools were effective at detecting future aggression and adverse incidents. We did not directly compare the HARM-FV and eHARM-FV.     

Female Suicide Rates in Ghizer,Pakistan

Suicide is an understudied subject in Pakistan. There are many social, legal, and religious sanctions against it. National rates of suicides are not known. We calculated suicide rates of women in the Ghizer District of the remote Northern Areas of Pakistan. During years 2000 to 2004, 49 women committed suicide. Taking average mean population for women for 5 years as 65,783, we calculated annual crude suicide rates for women as 14.89/100,000/year. For women over the age of 15 years, rates were 33.22/100,000/year; age‐specific rates for 15–24 years were 61.07/100,000 per year. These figures are considerably higher than suicide rates in other parts of Pakistan and may be related to high psychiatric morbidity in Pakistani women. This study underscores the need for a standardized system of registration of suicides in Pakistan. There is also urgent need to address high psychological distress in women in Pakistan.     

Linking family incivility to workplace incivility: Mediating role of negative emotions and moderating role of self‐efficacy for emotional regulation

The research on work‐related antecedents of workplace incivility (WI) is well‐established, yet relatively less attention has been paid to non‐work‐related experiences as key antecedents to employees’ incivility at work. Drawing upon the incivility spiraling framework and spillover theory, we use a moderated‐mediation model to investigate the impact of employees’ experience of family incivility on their behavioral WI through the mediation of negative emotions and the moderation of self‐efficacy for emotional regulation (SEER). The multisource field data also demonstrate general support for the hypothesized relationships. Findings revealed that negative emotions carry the spiraling effect from family incivility to WI. In addition, SEER moderated the positive direct relationship of experienced family incivility and negative emotions, and indirect association with behavioral WI. These findings have implications for theory and management alike, further suggesting directions for future research.
