Response to the Comments by Larichev,Korhonen and Vargas on ‘Power Relations and Group Aggregation in the Multiplicative AHP and SMART’

We are pleased to continue the open discussion in this journal and we hope that it will contribute to the clarification of the main issues. Aggregation by geometric means has been accepted as a technically sound procedure. The critical comments now seem to concentrate on the establishment of the Multiplicative AHP, the publication of a method for weighted voting before empirical verification, and the significance of negotiations in decision making. Several numerical examples illustrate the arithmetic-mean and geometric-mean calculations, and the legitimacy of rank reversal is revisited. We discuss the issues in the same order here. © 1997 by John Wiley & Sons, Ltd. J. Multi-Crit. Decis. Anal. 6 : 171–174 (1997) No. of Figures: 0. No. of Tables: 5. No. of References: 9.     

Scale sensitivity in the multiplicative AHP and SMART

We consider first a variant of the analytic hierarchy process (AHP) with a one-parametric class of geometric scales to quantify human comparative judgement and with a multiplicative structure: logarithmic regression to calculate the impact scores of the alternatives at the first evaluation level and a geometric-mean aggregation rule to calculate the final scores at the second level. We demonstrate that the rank order of the impact scores and final scores is scale-independent. Finally we show that the multiplicative AHP is an exponential version of the simple multi-attribute rating technique (SMART). In fact, the multiplicative AHP is concerned with ratios of intervals on the dimension of desirability, whereas SMART analyses differences in the corresponding orders of magnitude.     

The Multiplicative AHP,SMART and ELECTRE in a Common Context

This paper presents a comparative study of three popular methods for multicriteria decision analysis based on a particular model of human preferential judgement. Since decisions are invariably made within a given context, we model relative preferences as ratios of increments or decrements in an interval on an axis of desirability. Next we sort the ratio magnitudes into a small number of categories, represented by numerical values on a geometric scale. We explain why the analytic hierarchy process (AHP) and the French collection of ELECTRE methods, typically based on pairwise comparison methods, are concerned with categories of ratio magnitudes, whereas the simple multiattribute rating technique (SMART) essentially uses orders of magnitude of these ratios. This phenomenon provides a common basis for the analysis of the methods in question and for a cross-validation of their results. We illustrate the approach via a well-known case study, the choice of a location for a nuclear power plant. We conclude by discussing the scope of the comparative study. © 1997 John Wiley & Sons, Ltd.     

Stochastic pairwise comparative judgements and direct ratings of alternatives in the REMBRANDT system

The REMBRANDT system for multicriteria decision analysis consists of both the multiplicative variant of the AHP (which employs a method of pairwise comparative judgements by a decision maker to arrive at final impact scores for the alternatives under consideration) and SMART, the simple multiattribute rating technique (which utilizes direct rating of alternatives to achieve final impact scores). This paper examines the effect of imprecision or uncertainty in the decision maker's pairwise judgements or ratings of alternatives by expressing each pairwise judgement or rating as a probability distribution, and the structure of REMBRANDT's component models is exploited to derive interval judgements or interval ratings of the alternatives’ final impact scores. These interval judgements or interval ratings can be used to determine the probability of rank reversal amongst alternatives, i.e. to assess the stability of the final impact score vector. © 1998 John Wiley & Sons, Ltd.     

团体咨询成员的相互共情及其与效果的关系——社会关系模型在团体咨询研究中的应用

研究旨在探讨团体成员的相互共情及其与团体效果的关系。共收集10个团体,53名成员的数据,运用社会关系模型分析。结果发现：1.成员自评相互共情得分较高,但互评相关不显著;2.共情水平与会谈效果正相关,与团体反治疗性因素负相关;3.被共情水平与不信任负相关;4.共情准确性与团体治疗性因素正相关。结论：成员自评相互共情水平较高,但互评不匹配。成员自评共情水平越高,会谈效果越好,受团体反治疗性因素阻碍更少。越被准确评估情绪效价的成员,从治疗性因素中获益更多。     

Two new cases of rank reversals when the AHP and some of its additive variants are used that do not occur with the multiplicative AHP

Many researchers have long observed some cases in which certain ranking irregularities can occur when the original analytic hierarchy process (AHP), or some of its variants, are used. This paper presents two new categories of ranking irregularities which defy common intuition. These ranking irregularities occur when one decomposes a decision problem into a set of smaller problems each defined on two alternatives and the same criteria as the original problem. These irregularities are possible when the original AHP, or some of its additive variants, are used. Computational experiments on random test problems and an examination of some real‐life case studies suggest that these ranking irregularities are dramatically likely to occur. This paper also proves that these ranking irregularities are not possible when a multiplicative variant of the AHP is used. Copyright © 2001 John Wiley & Sons, Ltd.     

Generating consensus priority interval vectors for group decision‐making in the AHP

Many practical and important decision‐making problems are complicated by at least two factors: (1) the qualitative/subjective nature of some criteria often results in uncertainty in the individual ratings; and (2) group decision‐making is involved and some means of aggregating individual ratings is required. Traditionally, both individual and group priorities have been represented as point estimates, but this approach presents severe limitations for accommodating imprecision in the decision‐making process. This paper examines the group decision‐making problem in the context where priorities are represented as numeric intervals. A set of techniques that could be used at some of the phases of an analytic hierarchy process (AHP)‐based group decision‐making process, which has the objective of generating a ‘consensus’ priority that represents the group's opinion with regards to the relative importance of a set of N objects (e.g. criteria, alternatives), is presented.

Time complexity and consistency issues in using the AHP for making group decisions

Two different ways of using the AHP in making group decisions are compared and evaluated. The first method combines different experts’ opinions before applying an eigenvalue method to obtain final weights for decision alternatives. The second, in contrast, derives each expert's rating for the decision alternatives before combining them. Both methods take into account the relative importance of different experts in making decisions. Comparison and evaluation of these two methods are made by using two criteria: time complexity and consistency indices. A numerical example is provided to illustrate the use of these two methods, and results of a mathematical simulation are presented for comparing the time complexity in different-sized problems. © 1998 John Wiley & Sons, Ltd.     

Issues of Power, Control, and Status in Group Interaction: From Ferenczi to Foucault

Examination of the issues of power, control, and status in human interaction is made from the works of Kafka, Ferenczi, and Foucault. Ferenczi's confusion of tongues theory as a model is used to describe the dynamics of charismatic group leadership in training group for analyst group candidates.     

Rethinking Affective Experience and Popular Emotion: World War I and the Construction of Group Emotion in International Relations

Research in International Relations (IR) frequently confronts claims about the emotions shared by members of a group. While much attention has been devoted to the potential for affective and emotional experience beyond the individual level, IR scholars have said less about the politics of invoking popular emotion. This article addresses that gap. Specifically, we argue that between individual—and even shared—affective experience on the one hand and group‐based “popular emotion” on the other exists not mechanisms of aggregation but rather processes of framing, projection, and propagation that are deeply political. We distinguish between two tropes that commonly structure references to popular emotion: communal emotion, the idealized attribution of an authentic, unifying emotional response of “the people,” and mass emotion, a volatile and potentially dangerous mob‐like reaction, but one also susceptible to manipulation. Using the outbreak of World War I as a showcase, we demonstrate the political significance of popular emotion, including its enduring relevance for understanding contemporary populism.     

Relations of Power in Different Spaces: An Exploration of the Schooling Experiences of Children in an HIV/AIDS Context

In this article we explore how the concept of relations of power in different spaces plays out in the lives of school children living in an HIV/AIDS context, and how processes of inclusion and exclusion are associated with particular spaces. The article uses Foucault's (2000) identification of four distinct relations of power to argue that within different school spaces we find economic, political, judicial and epistemological relations of power that are embedded in the way children experience reality. The study was conducted in five primary schools, three secondary schools, one early Childhood Education (ECD) centre, a special school and their communities in the province of KwaZulu Natal. Participants were teachers, learners, out of school youth, and members of community organisations working in the district. Data collection methods included individual and focus group interviews. Within the focus group interviews various participatory research techniques were used, including ranking exercises, projective activities, transect walk, body mapping, photo voice. The findings in the study revealed three complex and contradictory schooling spaces: policy space, curriculum space, and safe spaces in which learners' schooling lives are played out. The study showed that space is fundamental in the exercise of power as revealed in the exclusionary and inclusionary ways in which children experienced their schooling lives.     

Self Psychology, Dreams and Group Psychotherapy: Working in the Playspace

This paper presents one leadership style within a self-psychological approach to working with dreams in group psychotherapy. It stresses an empathic attunement, the creation of safety, and an experience-near playful relationship. Playful is not used lightly here. It is used in the spirit of Winnicott's intermediate space where a mother suspends questions of what is real or not real and what is me and not me. Freud's analogy to a playspace forms a metaphor for the creation of a special atmosphere in a group, or for that matter in individual work as well, that encourages exploration, risk taking, and vulnerability. Working with dreams in this playspace deepens the curative process, not only for the dreamer, but for the entire group.

Multiculturalism and Group Therapy in the United States: A Social Constructionist Perspective

Multiculturalism encourages the inclusion of the broad range of cultural differences that exist in society into our therapeutic dialogues. This paper examines multicultural group therapy through the perspective of social constructionism. Emphasis is given to the unacknowledged and unspoken imbalance of power that exists in psychotherapeutic contexts. The concepts of multiple individual identity and cultural representation are discussed and illustrated with case examples. Clinical considerations for the multicultural group therapist are provided.     

Large Group Intervention to Encourage Dialogue Between Directors and Workers in the Context of Organizational Ambiguity

In the postmodern era the entire sphere of employment is undergoing changes that create feelings of ambiguity. These changes are reflected in the use of defense mechanisms such as splits between management and employees, and alienation and dissociation. Occupational social workers are also experiencing insecurity. Although their function is to assist individuals and the organization during crises, they are not able to detach themselves from their experiences. It is more difficult for them resort to bridging and dialogue in order to ameliorate feelings of anxiety. This article will describe how a large group intervention can provide practical experience that raises self-awareness and facilitates coping with organizational ambiguity.     

Political Power and Race Relations in South Africa: African Attitudes Before and After the Transition

When an oppressed majority finally gains political power, what happens to its attitudes to its erstwhile oppressor, and to its perceptions and feelings about its socioeconomic disadvantages that were established during its oppression? Longitudinal data from pre- and post-transition surveys of black South African college and high school students indicate marked reductions in perceptions of and outrage about intergroup socioeconomic inequity and deprivation relative to English-speaking and Afrikaans-speaking whites, but no change in attitudes toward these groups or toward whites in general. The findings are discussed in terms of contemporary theory and research on justice, intergroup relations, and group conflict. Some tentative implications for the prospects for a democratic political culture in South Africa are noted.     

Emotional Intelligence and the Identity Negotiation of a Racial Minority Group in a Majority School Context

This article describes the possible impact of emotional intelligence on identity negotiation of a racial minority group in a majority school context. The study investigated the adjustment and functioning of racial minority groups in majority school contexts, as well as the identity negotiation associated with it, and determined whether there is a correlation between the former and the Emotional Intelligence (EI) of the participants. Participants were 16 black and 21 white learners attending two schools where they were in the minority (mean age = 16.23 years; SD = 1.49 years). The learners attended Grades 9–12. Data were first organised, after which themes and patterns were identified, and the data appraised and categorised (Creswell, 2007), after which a comparison was drawn between the identified categories of existing knowledge. Findings suggest that racial integration in both high schools actually occurred in name only; most participants chose to mingle within their own racial groups and the black participants in particular were exposed to racism, discrimination and prejudice on a regular basis. Despite the necessary steps taken and implemented by government in order to oppose racism in the country and promote racial integration in schools, it seems that the consequences of apartheid remain for the foreseeable future.
