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.     

‘How can we help when she won't tell us what's wrong?’ Professionals working with South Asian women who have experienced sexual abuse

In this paper, we explore some of the issues facing professionals in the UK currently involved in providing services for South Asian women who have experienced sexual abuse. The study describes part of a wider Economic and Social Research Council funded project, based upon interviews and focus groups with both professionals and women survivors of sexual abuse. Drawing on semi‐structured interviews and two focus groups with 37 professionals including psychological therapists, refuge and project workers, from a range of organisations, our aim in this paper is to provide a discursive analysis of some of the key dilemmas faced by professionals working with sexual abuse in South Asian communities by exploring two central interpretive repertoires: ‘culture not self’ and ‘symptom talk as solution’. The analysis indicates that professionals face a series of dilemmas when working with South Asian women survivors. They highlight the tension between individualised models of personhood in many psychological therapies and the challenge to these by South Asian communities who hold a more relational view of the person. One of the strategies used by professionals to work with the tensions between ‘culture’ and the ‘reality’ of the survivor's pain was the translation of women's distress into symptoms of mental disorder. However, the consequences of this intervention raised some serious issues, including further pathologisation and stigma. The implications of these findings will be discussed in terms of how to understand the experiences of South Asian women from a more socially grounded perspective and to explore the issues they face in accessing and receiving appropriate services to deal with the aftermath of sexually abusive experiences.

Muslim Discrimination: Evidence From Two Lost‐Letter Experiments

Since the 9/11 terrorist attacks, there has been considerable concern about whether Muslims living in Western countries are targets of prejudice. A considerable amount of survey‐based evidence suggests that Muslims are victims of discrimination. This paper tested this hypothesis. Two lost‐letter experiments were conducted to test whether the difference in returned letters would be attributable to whether the addressee was Muslim or Swedish. The results show that Muslims receive far fewer letters than do Swedes. However, this discrimination only appears when the lost letters contain money; in which case, the finder gains by not posting the letter.     

Influence of Zn incorporation on the microstructural and magnetic properties of La0.67Sr0.33Mn1−xZnxO3 nanoparticles synthesised by the sol–gel method

Perovskite manganite nanoparticles with the chemical formula La_0.67Sr_0.33Mn_1?xZn_xO₃ (x = 0, 0.1 and 0.2) were prepared by the sol–gel process and the influence of Zn substitution on their microstructural and magnetic properties studied in detail. X-ray diffractometry (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were employed for crystal structure determination and microstructural analysis. The results of XRD analysis confirmed the polycrystalline nature and rhombohedral crystal structure with space group R(-3c) for all compositions. SEM micrographs of the samples revealed an agglomeration/well-connected appearance of the particles. The composition and uniform distribution of all the elements were established by energy-dispersive spectroscopy. TEM images clearly confirmed an almost spherical shape of the nanoparticles with an average particle size of about 11, 14 and 13 nm for the 0, 10 and 20% Zn-doped samples, respectively. The magnetic behaviour of the nanoparticles was studied at room temperature with a vibrating sample magnetometer (VSM) up to a field of 1.8 Tesla. These measurements established a superparamagnetic nature with a variation in the saturation magnetization (M_s) with Zn content.
