Random error in additive decompositions of multiattribute utility

Decomposition is a common strategy for dealing with the complexity of multiattribute decision problems. A cognitively demanding task is broken down into tasks requiring simpler, perhaps easier, judgments which can then be aggregated. But individual judgments can be inconsistent in systematic or random fashion and when aggregated there is the possibility of propagation of this inconsistency. In this paper inconsistency in the form of random error is investigated in the context of additive decomposition of multiattribute utility. The process of aggregation of random error is studied and a comparison made with random error in holistic estimates of multiattribute utility. Conditions under which decomposition improves the consistency of the multiattribute utility estimate are presented and discussed.     

Random error reduction in analytic hierarchies: a comparison of holistic and decompositional decision strategies

The principle of ‘divide and conquer’ (DAC) suggests that complex decision problems should be decomposed into smaller, more manageable parts, and that these parts should be logically aggregated to derive an overall value for each alternative. Decompositional procedures have been contrasted with holistic evaluations that require decision makers to simultaneously consider all the relevant attributes of the alternatives under consideration (Fischer, 1977 ). One area where decompositional procedures have a clear advantage over holistic procedures is in the reduction of random error (Ravinder, 1992 ; Ravinder and Kleinmuntz, 1991 ; Kleinmuntz, 1990 ). Adopting the framework originally developed by Ravinder and colleagues, this paper details the results of a study of the random error variances associated with another popular multi‐criteria decision‐making technique, the Analytic Hierarchy Process (AHP); (Saaty, 1977 , 1980 ), as well as the random error variances of a holistic version of the Analytic Hierarchy Process (Jensen, 1983 ). In addition, data concerning various psychometric properties (e.g. the convergent validity and temporal stability) and values of AHP inconsistency are reported for both the decompositional and holistic evaluations. The results of the study show that the Ravinder and Kleinmuntz ( 1991 ) error‐propagation framework extends to the AHP and decompositional AHP judgments are more consistent than their holistic counterparts.

Attribute weighting methods and decision quality in the presence of response error: a simulation study

This paper uses a simulation approach to investigate how different attribute weighting techniques affect the quality of decisions based on multiattribute value models. The weighting methods considered include equal weighting of all attributes, two methods for using judgments about the rank ordering of weights, and a method for using judgments about the ratios of weights. The question addressed is: How well does each method perform when based on judgments of attribute weights that are unbiased but subject to random error? To address this question, we employ simulation methods. The simulation results indicate that ratio weights were either better than rank order weights (when error in the ratio weights was small or moderate) or tied with them (when error was large). Both ratio weights and rank order weights were substantially superior to the equal weights method in all cases studied. Our findings suggest that it will usually be worth the extra time and effort required to assess ratio weights. In cases where the extra time or effort required is too great, rank order weights will usually give a good approximation to the true weights. Comparisons of the two rank-order weighting methods favored the rank-order-centroid method over the rank-sum method. © 1998 John Wiley & Sons, Ltd.     

The relation between depression and appreciation: The role of perceptions of emotional utility in an experimental test of causality

The present research examined the potential role of perceived utility of appreciation in depressive symptoms. In a between-subjects design, participants were induced to increase their experience of appreciation or their perceived usefulness of appreciation. Self-reported perceptions of emotional utility, actual experience of emotion, as well as depression scores gathered from semi-structured interviews, were obtained at baseline and post-induction. As predicted, although participants in both groups evidenced lower levels of depressive symptoms at post-induction than at baseline, there was a greater decrease among participants in the appreciation-utility condition than among those in the appreciation-experience condition. Further, perceived utility of appreciation was an important mediator in moderated mediation models.     

Summarizing slant perception with words and hands; an empirical alternative to correlations in Shaffer,McManama, Swank,Williams & Durgin (2014)

The paper by Shaffer, McManama, Swank, Williams & Durgin (2014) uses correlations between palm-board and verbal estimates of geographical slant to argue against dissociation of the two measures. This paper reports the correlations between the verbal, visual and palm-board measures of geographical slant used by Proffitt and co-workers as a counterpoint to the analyses presented by Shaffer and colleagues. The data are for slant perception of staircases in a station (N = 269), a shopping mall (N = 229) and a civic square (N = 109). In all three studies, modest correlations between the palm-board matches and the verbal reports were obtained. Multiple-regression analyses of potential contributors to verbal reports, however, indicated no unique association between verbal and palm-board measures. Data from three further studies (combined N = 528) also show no evidence of any relationship. Shared method variance between visual and palm-board matches could account for the modest association between palm-boards and verbal reports.     

Using sonic branding in the retail environment — an easy and effective way to create consumer brand loyalty while enhancing the in‐store experience

Retail is no longer simply a point of purchase, it has now become part of a brand's communications strategy. As brands begin to explore the benefits of the retail environment they are mostly failing to utilise fully its ability to communicate with all the senses. Sonic branding has yet to make a significant impact on the retail environment and yet it is a powerful tool in the development of brand loyalty. As brands search for new ways of communicating with consumers both locally and globally, sonic branding will become a key tool in the creation of fully immersive brand experiences.

Cognitive testing in non‐demented Turkish immigrants ‐ comparison of the RUDAS and the MMSE

Nielsen, T. R. Vogel, A., Gade, A. & Waldemar, G. (2012). Cognitive testing in healthy Turkish immigrants ‐ comparison of the RUDAS and the MMSE. Scandinavian Journal of Psychology 53, 455–460. Methods for culturally and linguistically appropriate cognitive testing of elderly minority populations are lacking in Europe. The aim of this study was to compare performance on the Rowland Universal Dementia Assessment Scale (RUDAS) and the Mini Mental State Examination (MMSE) in Turkish immigrants in Denmark and determine the impact of demographic and health‐related variables on test performance. A sample of non‐demented community‐dwelling Turkish immigrants was recruited from the greater Copenhagen area. All participants completed a structured interview regarding demographic, physical and mental health status, as well as measures of depression and acculturation, and cognitive testing with the RUDAS and the MMSE. A total of 76 non‐demented participants aged 50 or more were included in the study. The mean performance on the RUDAS and the MMSE was 26.8 (SD 2.4) and 23.7 (SD 4.3), respectively. In group comparisons, correlation analyses and regression analyses, level of schooling represented a more significant variable for RUDAS and MMSE performance than any other variable. However, the impact of schooling was considerably more pronounced on the MMSE and the test was not found to be a valid measure of general cognitive function in subjects with less than five years of schooling. Although not entirely free of educational bias, the RUDAS can be a valuable supplement to the MMSE for assessment of general cognitive function in Turkish minority populations.     

The gender paradigm in domestic violence research and theory: Part 1—The conflict of theory and data

Feminist theory of intimate violence is critically reviewed in the light of data from numerous incidence studies reporting levels of violence by female perpetrators higher than those reported for males, particularly in younger age samples. A critical analysis of the methodology of these studies is made with particular reference to the Conflict Tactics Scale developed and utilised by Straus and his colleagues. Results show that the gender disparity in injuries from domestic violence is less than originally portrayed by feminist theory. Studies are also reviewed indicating high levels of unilateral intimate violence by females to both males and females. Males appear to report their own victimization less than females do and to not view female violence against them as a crime. Hence, they differentially under-report being victimized by partners on crime victim surveys. It is concluded that feminist theory is contradicted by these findings and that the call for “qualitative” studies by feminists is really a means of avoiding this conclusion. A case is made for a paradigm having developed amongst family violence activists and researchers that precludes the notion of female violence, trivializes injuries to males and maintains a monolithic view of a complex social problem.     

Religious Ambivalence,Liminality, and the Increase of No Religious Preference in the United States, 2006–2014

Americans identified less and less with organized religion over the past two decades. Yet apparently, many people who no longer identify with a religion are not consistently nonreligious. Reinterviews reveal that many people who express no religious preference in one survey name a religion when asked the same question in a subsequent interview. Past research called this phenomenon a “liminal” status. This article improves estimates of liminality by using three interviews and a better statistical model. About 20 percent of Americans were liminal in recent years, 10 percent were consistently nonreligious, and 70 percent were consistently religious. Falling religious identification in cross‐sectional data over the last three decades reflects slow change in religious identity, but some of the rise of the nones is due to more liminals saying they have no religion. Liminals appear equally among people raised conservative Protestant, mainline Protestant, or Catholic.     

Practical Matters and Ultimate Concerns, “Doing,” and “Being”: A Diary Study of the Chaplain's Role in the Care of the Seriously Ill in an Urban Acute Care Hospital

Systematic observational studies of the chaplain's role and function in the secular health‐care setting are few. With an episode‐based diary recorded on handheld digital tablets, palliative care chaplains at a large urban hospital with a diverse patient population recorded details of patient visits in near‐real time. Cluster analysis revealed groups of activities we called "doing" and "being," and conversation topics of "practical matters" and "ultimate concerns”; chaplains were most satisfied with visits that involved all of these. Chaplains offer patients and families a space to express significant concerns; however, visits with spiritual or religious activities or topics were relatively rare. Broad quality of life concerns are central to the evolving professional role of chaplains in the secular setting of the modern hospital.     

Rivers of milk and honey ‐ an exploration of nurturing the self in a Russian context

This paper is an exploration of the relationship between nurturing in all its contexts ‐ among them, the nursing couple and the therapeutic relationship ‐ and the evolution of an individual self. The ideas are illustrated by a case vignette of a Russian patient. An attempt is made to show that when the self as an integral unity of body and soul is addressed in the analytic setting, ‘nutritional dreams’ emerge as expressions of the self‐in‐action. Certain psycholinguistic features of the Russian cultural context are described which suggest a link of meaning between development of the self and secure parenting. This linguistic association may facilitate the process of self‐centering.     

Validation of a 28‐item version of the Systemic Clinical Outcome and Routine Evaluation in an Irish context: the SCORE‐28

This article describes the development, in an Irish context, of a three‐factor, twenty‐eight‐item version of the Systemic Clinical Outcome and Routine Evaluation (SCORE) questionnaire for assessing progress in family therapy. The forty‐ item version of the SCORE was administered to over 700 Irish participants including non‐clinical adolescents and young adults, families attending family therapy, and parents of young people with physical and intellectual disabilities and cystic fibrosis. For validation purposes, data were also collected using brief measures of family and personal adjustment. A twenty‐eight‐item version of the SCORE (the SCORE‐28) containing three factor scales that assess family strengths, difficulties and communication was identified through exploratory principal components analysis. Confirmatory factor analysis showed that the factor structure of the SCORE‐28 was stable. The SCORE‐28 and its three factor scales were shown to have excellent internal consistency reliability, satisfactory test‐retest reliability and construct validity. The SCORE‐28 scales correlated highly with the General Functioning Scale of the Family Assessment Device, and moderately with the Global Assessment of Relational Functioning Scale, the Kansas Marital and Parenting Satisfaction Scales, the Satisfaction with Life Scale, the Mental Health Inventory – 5, and the total problems scale of the Strengths and Difficulties Questionnaire. Correlational analyses also showed that the SCORE‐28 scales were not strongly associated with demographic characteristics or social desirability response set. The SCORE‐28 may routinely be administered to literate family members aged over 12 years before and after family therapy to evaluate therapy outcome.
