Bias-corrected estimation of the Rudas–Clogg–Lindsay mixture index of fit

Rudas, Clogg, and Lindsay (1994, J. R Stat Soc. Ser. B, 56, 623) introduced the so-called mixture index of fit, also known as pi-star (π*), for quantifying the goodness of fit of a model. It is the lowest proportion of ‘contamination’ which, if removed from the population or from the sample, makes the fit of the model perfect. The mixture index of fit has been widely used in psychometric studies. We show that the asymptotic confidence limits proposed by Rudas et al. (1994, J. R Stat Soc. Ser. B, 56, 623) as well as the jackknife confidence interval by Dayton ( 2003 , Br. J. Math. Stat. Psychol., 56, 1) perform poorly, and propose a new bias-corrected point estimate, a bootstrap test and confidence limits for pi-star. The proposed confidence limits have coverage probability much closer to the nominal level than the other methods do. We illustrate the usefulness of the proposed method in practice by presenting some practical applications to log-linear models for contingency tables.     

Body Image: A Study in a Tri-Ethnic Sample of Low Income Women

This study was designed to examine the evaluative, affective, and behavioral components of body image among 1,217 low-income European American, African American, and Latina women. Participants completed a multidimensional body image questionnaire while awaiting an outpatient clinic appointment. Body mass index (BMI) was determined by medical chart review. Nearly all normal weight and a number of overweight and obese African Americans characterized their weight as normal. In contrast, nearly all overweight and obese European Americans and Latinas regarded themselves as overweight as did over 30% of those of normal weight. European Americans and Latinas with higher BMIs reported more appearance shame than their lower BMI peers did; this pattern was not observed among African Americans. Among Latinas, body image was influenced by length of residency in the U.S. Dr. Berenson is supported by Grant Number K24HD043659, a Midcareer Investigator Award in Patient-Oriented Research, from the National Institute of Child Health and Human Development.

With Hope and Imagination: Imaginative Moral Decision-Making in Neonatal Intensive Care Units

Although the role of imagination in moral reasoning is often neglected, recent literature, mostly of pragmatist signature, points to imagination as one of its central elements. In this article we develop some of their arguments by looking at the moral role of imagination in practice, in particular the practice of neonatal intensive care. Drawing on empirical research, we analyze a decision-making process in various stages: delivery, staff meeting, and reflection afterwards. We show how imagination aids medical practitioners demarcating moral categories, tuning their actions, and exploring long-range consequences of decisions. We argue that imagination helps to bring about at least four kinds of integration in the moral decision-making process: personal integration by creating a moral self-image in moments of reflection; social integration by aiding the conciliation of the diverging perspectives of the people involved; temporal integration by facilitating the parties to transcend the present moment and connect past, present, and future; and epistemological integration by helping to combine the various forms of knowledge and experience needed to make moral decisions. Furthermore, we argue that the role of imagination in these moral decision-processes is limited in several significant ways. Rather than being a solution itself, it is merely an aid and cannot replace the decision itself. Finally, there are also limits to the practical relevance of this theoretical reflection. In the end, it is up to care professionals as reflective practitioners to re-imagine the practice of intensive care and make the right decisions with hope and imagination.

Witnessing to Hope in the Christian Community Through Irony

The concept of witnessing to hope reminds us that nurturing hope is fundamentally a communal endeavor. In the Christian tradition, this witnessing takes a particular form. It involves the use of the ironic imagination: Death leads to new life, the poor are considered blessed, and the faithful boast in their suffering. It is argued that a central pastoral task is stimulating the ironic imagination. While this can take place in a number of settings, the focus here is on public worship. Practical examples of how this task might be executed are offered.

脑电双频指数（BIS）对脊柱侧凸矫正术中唤醒时间的影响

探讨脑电双频指数（bispectral index,BIS）监测不同镇静深度对脊柱侧凸矫正术中唤醒时间的影响,60例行脊柱侧凸矫正手术的患者随机分为三组,Ⅰ组BIS30～40,Ⅱ组BIS40～50和Ⅲ组BIS50～60,评价各组患者的唤醒时间及不良事件发生率。结果显示Ⅰ组唤醒时间为（18．13±2．3）min,明显长于Ⅱ组和Ⅲ组的唤醒时间。而当BIS为40～50时,患者术中的不良事件发生率明显低于另外两组。所以,使用BIS进行全麻镇静深度的监测,在唤醒前将镇静深度维持在BIS40～50是合适的。     

Body appreciation, media influence, and weight status predict consideration of cosmetic surgery among female undergraduates

The current study examined the association between consideration of cosmetic surgery, body appreciation, media influence, and participant demographics. In total, 322 female university students completed the Consider subscale of the Acceptance of Cosmetic Surgery Scale, the third revision of Sociocultural Attitudes Toward Appearance Scale (SATAQ-3), the Body Appreciation Scale (BAS), and provided their demographic details. Bivariate correlations showed that consideration of cosmetic surgery was significantly and positively correlated with three of the SATAQ-3 subscales and negatively correlated with BAS scores, age, and body mass index (BMI). A multiple regression showed that the only significant predictors of consideration of cosmetic surgery were greater media influence, less body appreciation, and lower BMI. These results are discussed in relation to the extant literature on attitudes towards cosmetic surgery.     

From horror to ethical responsibility: Carl Gustav Jung and Stephen King encounter the dark half within us,between us and in the world

This paper explores the experience of horror. The term is usually understood collectively to refer to experiences of terrorism, racism and other conflicts; however, the paper explores the equal horror for the individual of facing deep and painful psychic contents and traumatic experiences. The paper explores the way that both C.G. Jung, through analysis of the psyche, and the author Stephen King, through his horror novels, have accepted and explored the experience of encountering ‘the dark half’ or ‘It’ that is the other within themselves, forming images and symbols capable of linking their personal experience to that of the collective. This encounter is transformed, as far as Jung is concerned by analytical psychology and for King by fiction, through an attitude of active imagination. This led both men to developing an ethical responsibility towards the images of the unconscious, as well as the personal and collective contents of human life. The paper depicts how encountering the ‘dark half’, through Jung and King can provide a Jungian analyst with a special attitude with which to deeply explore and ethically process the experience of horror in different fields, including therapeutic practice, analytical training and in the traumatic and conflictual facing of the other, with which, today as always, the world presents us.     

The snake in the mandala: dialogical aspects of Jung’s ‘A study in the process of individuation’

Jung’s study centres on the amplification of pictures painted by a woman patient and posits their sequence as evincing the initial stages of the individuation process. His text performs a dialogue with its audience whereby Jung persuades us of this truth, and also reveals Jung’s dialogue with his patient and with his own ideas. The present paper revisits the clinical material first with a focus on the interaction between Jung and his patient. The second part compares the 1940 and 1950 versions of Jung’s study with attention to tensions that traverse them, such as Jung’s attitude to the animus and his two voices as a practitioner and a theorist.     

情绪应激体液免疫调节作用的影响因素

以给予经定时喂水训练大鼠空瓶刺激为情绪性心理直激源,研究了应激源给予的频率及抗原免疫前或后给予应激刺激等因素对此情绪应激体液免疫调节作用的影响：结果表明,特异性抗原OVA免疫前3次,每次30分钟的情绪应激刺激不影响大鼠的抗OVA抗体水平和脾脏指数;抗原免疫后,同样频率和持续时间的情绪应激能一定程度地降低体液免疫功能;而抗原免疫后14次,每次10分钟的情绪应激刺激则显著降低大鼠的抗OVA抗体水平和脾脏指数。该研究证实,抗原免疫后、反复多次的情绪应激刺激能显著抑制大鼠的原发性体液免疫功能。     

A multicriteria assignment problem

Our objective in this paper is to propose a procedure for solving a multicriteria assignment problem. Given qualitative and quantitative data, the proposed procedure makes assignments taking into consideration the multicriteria aspect of the problem. As an illustrative example, we consider the assignment of referees to the football matches in an Italian championship. Copyright © 2003 John Wiley & Sons, Ltd.
