An alternating least squares method for the weighted approximation of a symmetric matrix

Bailey and Gower examined the least squares approximationC to a symmetric matrixB, when the squared discrepancies for diagonal elements receive specific nonunit weights. They focussed on mathematical properties of the optimalC, in constrained and unconstrained cases, rather than on how to obtainC for any givenB. In the present paper a computational solution is given for the case whereC is constrained to be positive semidefinite and of a fixed rankr or less. The solution is based on weakly constrained linear regression analysis.The authors are obliged to John C. Gower for stimulating this research.     

Begging the Question in Arguments Based on Testimony

Summary This paper studies some classic cases of the fallacy of begging the question based on appeals to testimony containing circular reasoning. For example, suppose agents a, b and c vouch for d’s credentials, and agents b, d, and e vouch for a’s credentials. Such a sequence of reasoning is circular because a is offering testimony for d but d is offering testimony for a. The paper formulates and evaluates restrictions on the use of testimonial evidence that might be used to deal with such problematic arguments. One is called the Non-repeater Rule: in an extended sequence of argumentation based on testimony, once a source x has been appealed to at any given point in the sequence, that same source x must never be appealed to again at any next point in the same sequence.     

PERSONALITY AND BEHAVIOURAL MEASURES: GENDER,AGE, AND RACE CONTRASTS IN AN AUSTRALIAN SETTING*

As a complement to previous comparative studies focusing on cognition, this study compares a number of personality and behavioural traits of Australian Anglocelt and Aboriginal children. The personality scales are Extraversion (E), Neuroticism (N), Psychoticism (P), Lie (L), Impulsiveness (Imp), Venturesomeness (Vent), and Empathy (Emp); and the behavioural scales are Relating (R), Asserting (A), Investing (I). and Coping (C). The personality scales were administered to 113 and 42 sixth- and ninth-grade children, respectively. The teachers of the children completed a behavioural rating scale for each child. Thirty-three sixth-graders and 16 ninth-grader were Aboriginal. Sixth-grade males had higher means on P and Vent, while sixth-grade females averaged higher on L, Emp, R, I, and C. Aboriginal sixth-graders averaged higher on P, while Aboriginals overall averaged higher on E, R, A, I, and C than Anglocelts. Ninth-grade males averaged significantly higher on E, Imp, and Vent, and lower on L. The only significant difference for ninth-graders was that Aboriginals averaged higher on L. These results indicate cultural influences bearing upon contact, and support previous informal judgements that Aboriginal children tend to be more reserved in response to formal situations than Anglocelts. Implications are inferred for educational policy.     

Faking on a situational judgment test in a medical school selection setting: Effect of different scoring methods?

We examined the occurrence of faking on a rating situational judgment test (SJT) by comparing SJT scores and response styles of the same individuals across two naturally occurring situations. An SJT for medical school selection was administered twice to the same group of applicants (N = 317) under low‐stakes (T1) and high‐stakes (T2) circumstances. The SJT was scored using three different methods that were differentially affected by response tendencies. Applicants used significantly more extreme responding on T2 than T1. Faking (higher SJT score on T2) was only observed for scoring methods that controlled for response tendencies. Scoring methods that do not control for response tendencies introduce systematic error into the SJT score, which may lead to inaccurate conclusions about the existence of faking.     

Different temporary work status, different behaviors in organization

This study examined the contributions of the psychological contract framework to an understanding of the effects of different work statuses on employees’ behavior. We compared temporary firm workers (n=71) with core workers (n=268) and direct-hire temporary workers (n=149) with core workers (n=42) in two different samples. As expected, temporary firm workers consider that they receive fewer socio-emotional inducements from the organization they work for (opportunities for promotion, career development, long-term employment), but direct-hire temporary workers who succeeded in having their contracts extended had a psychological contract in which socio-emotional components predominated. A psychological contract with a predominance of socio-emotional components was important for organizations because it mediated the influence of work status on civic virtue behaviors on the part of temporary firm workers, and directly and positively influenced these behaviors in direct-hired temporary workers (behaviors as assessed by their supervisors). Contrary to the hypothesis, psychological contract had a direct and positive influence on the in-role behavior of direct-hire temporary workers. The implications of the findings for psychological contract research are discussed.     

The Imperative of Diakonia for the Church and Theological Education

This article begins by arguing that diakonia is an imperative for the church, be it at the local, national, regional, or global level. It goes on to describe how diakonia has been part of the identity of the World Council of Churches during its 70 years of existence, and highlights the struggle of diakonia and development within the fellowship and ecumenical partners. The article focuses on the document Called to Transformative Action: Ecumenical Diakonia as the most recent attempt to reflect on who we are and what we do as church. It identifies one important aspect of diakonia as reflected in the Pan‐African Women's Ecumenical Empowerment Network perspective on theological education. The article concludes by reflecting on the author's vision for a just community of women and men in prophetic diakonia.     

The Translation Issues in the Gender Inclusive Controversy

Abstract

The recently published Today's New International Versionhas received some criticism, especially from The Council on Biblical Manhood and Womanhood, which argues that the TNIVhas gone beyond translation to interpretation in order to further feminist causes. The present author argues that the differences between the TNIVand NIVare standard translation issues, highlighting three key points with illustrations, establishing a case for the superiority of “gender inclusive” translations such as the TNIV. A bibliography for study on both sides is included.     

Democratic Answers to Complex Questions – An Epistemic Perspective

This paper addresses a problem for theories of epistemic democracy. In a decision on a complex issue which can be decomposed into several parts, a collective can use different voting procedures: Either its members vote on each sub-question and the answers that gain majority support are used as premises for the conclusion on the main issue (premise based-procedure, pbp), or the vote is conducted on the main issue itself (conclusion-based procedure, cbp). The two procedures can lead to different results. We investigate which of these procedures is better as a truth-tracker, assuming that there exists a true answer to be reached. On the basis of the Condorcet jury theorem, we show that the pbp is universally superior if the objective is to reach truth for the right reasons. If one instead is after truth for whatever reasons, right or wrong, there will be cases in which the cbp is more reliable, even though, for the most part, the pbp still is to be preferred.     

Functional analysis and etiology

Cummins (1982) argues that etiological considerations are not onlyinsufficient butirrelevant for the determination offunction. I argue that his claim of irrelevance rests on a misrepresentation of the use of functions in evolutionary explanations. I go on to suggest how accepting anetiological constraint on functional analysis might help resolve some problems involving the use of functional explanations.Thanks to Bill Wimsatt, Greg Mikkelson, Dan McShea, Robert Cummins and the editor and referees of this journal for their comments on earlier drafts.     

Improved Fisher z estimators for univariate random‐effects meta‐analysis of correlations

Several authors have studied or used the following estimation strategy for meta‐analysing correlations: obtain a point estimate or confidence interval for the mean Fisher z correlation, and transform this estimate to the Pearson r metric. Using the relationship between Fisher z and Pearson r random variables, I demonstrate the potential discrepancy induced by directly z‐to‐r transforming a mean correlation parameter. Point and interval estimators based on an alternative integral z‐to‐r transformation are proposed. Analytic expressions for the expectation and variance of certain meta‐analytic point estimators are also provided, as are selected moments of correlation parameters; numerical examples are included. In an application of these analytic results, the proposed point estimator outperformed its usual direct z‐to‐r counterpart and compared favourably with an estimator based on Pearson r correlations. Practical implications, extensions of the proposed estimators, and uses for the analytic results are discussed.     

Weak measurement invariance with respect to unmeasured variables: An implication of strict factorial invariance

Measurement bias refers to systematic differences across subpopulations in the relation between observed test scores and the latent variant underlying the test scores. Comparisons of subpopulations with the same score on the latent variable can be expected to have the same observed test score. Measurement invariance is therefore one of the key issues in psychological testing. It has been established that strict factorial invariance (SFI) with respect to a selection variable V almost certainly implies weak measurement invariance with respect to V: given SFI, means and variances of observed scores do not depend on V. It is shown that this result can be extended. SFI in groups derived by selection on V has implications not only for V but also for potentially biasing variables W, if W and the selection variable V and/or if W and the factor underlying the observed test scores are statistically dependent. Given SFI with respect to V and prior knowledge concerning these dependencies, it is not necessary to measure and model variables W in order to exclude them as potentially biasing variables if the investigation focuses on groups selected on V.     

Older adult research in the Journal of Counseling Psychology,The Counseling Psychologist,and Counselling Psychology Quarterly: A 15-year review and implications for research

In preparing for an aging global population, older adults’ well-being has become an urgent priority across the world. Counseling psychologists have also called upon the field for more empirical attention on older adults. Yet, a review of the literature revealed that older adults were represented in less than 2% of all the articles in the Journal of Counseling Psychology (JCP) and The Counseling Psychologist (TCP) from 1991 to 2000. The current study presents a follow-up review of older adult research in counseling psychology literature between 2001 and 2015 in the following mainstream journals: Counselling Psychology Quarterly (CPQ), JCP, and TCQ. Results suggest a decline in the past 15 years, with less than 1% of the total articles in JCP, TCP, and CPQ devoted to older adults. Most of the studies employed cross-sectional survey research design to examine predictors of mental health. A number of studies focused on culture-specific experiences of diverse older adults. Implications and suggestions for future research on older adult issues are discussed in relation to the principles and interests rooted in the field of counseling psychology.     

Subjective determinants of attraction: Self-perceived causes of the rise and decline of liking,love, and being in love

Eighty-one female students at a German university were asked to indicate in writing (a) how they would come to like, love, and be in love with someone, and (b) how in their case liking, loving, and being in love with someone would come to an end. The responses were analyzed using a comprehensive list of 117 determinants developed for this study, which were grouped into four causal categories–P (person), O (other), P×O (relational), and E (environmental) conditions. Regarding the rise of attraction, the most frequent determinant for liking and for being in love was the existence of positive attributes of O (69% and 63%); for love, it was the existence of positive feelings from O (29%). Regarding the decline of attraction, the most frequent determinant for liking was negative behavior on O's part (42%); for love, abuse of one's trust by O (25%); and for being in love, disillusionment with regard to O (44%). Further analyses (including ANOVAs) involved the mean frequencies for the four causal categories. Concerning the rise of attraction sentiments, P causes were predominant for love and O causes were predominant for liking and for being in love; P×O causes were particularly infrequent for being in love. Concerning the decline of attraction sentiments, only for liking was one causal category predominant (O causes). E causes were hardly mentioned for both the rise and the decline focus. The findings are discussed in the context of both the more traditional research on “objective” determinants of attraction and, in particular, of recent research on the subjective (common-sense or implicit) understanding of liking, love, and being in love.     

A Confucian Interpretation of Creativity

This article explores a Confucian interpretation of creativity with reference to two classics—Analects and Mencius. A Confucian understanding of creativity centers on yi (appropriateness) and is motivated by shu (empathy) for the purpose of broadening dao (Way). Confucian creativity is manifested in two main ways: novelty through original interpretations of the objective world; and appropriateness through flexible responses to concrete circumstances synchronically and diachronically. Two major implications for research on creativity are highlighted. The first is that a Confucian approach to creativity extends the existing research on personal creativity by foregrounding the moral and interpersonal elements. Secondly, Confucian creativity synthesizes novelty and appropriateness, thereby challenging the essentialization of creativity and creative abilities of East Asians. A Confucian conception of creativity transcends a narrow focus on specific creative acts to a broader consideration of the agents, relationships, socio-cultural contexts and related moral issues.     

A Sequent Formulation of Conditional Logic Based on Belief Change Operations

Peter Gärdenfors has developed a semantics for conditional logic, based on the operations of expansion and revision applied to states of information. The account amounts to a formalisation of the Ramsey test for conditionals. A conditional A > B is declared accepted in a state of information K if B is accepted in the state of information which is the result of revising K with respect to A. While Gärdenfors's account takes the truth-functional part of the logic as given, the present paper proposes a semantics entirely based on epistemic states and operations on these states. The semantics is accompanied by a syntactic treatment of conditional logic which is formally similar to Gentzen's sequent formulation of natural deduction rules. Three of David Lewis's systems of conditional logic are represented. The formulations are attractive by virtue of their transparency and simplicity.     

Answer Sets and Qualitative Decision Making

Logic programs under answer set semantics have become popular as a knowledge representation formalism in Artificial Intelligence. In this paper we investigate the possibility of using answer sets for qualitative decision making. Our approach is based on an extension of the formalism, called logic programs with ordered disjunction (LPODs). These programs contain a new connective called ordered disjunction. The new connective allows us to represent alternative, ranked options for problem solutions in the heads of rules: A × B intuitively means: if possible A, but if A is not possible then at least B. The semantics of logic programs with ordered disjunction is based on a preference relation on answer sets. We show that LPODs can serve as a basis for qualitative decision making.     

An adjusted measure of achievement motivation for males and females and effects of future orientation on level of performance

An adjusted measure of achievement motivation was devised with the combined use of the Mehrabian Achievement Scale (Educational and Psychological Measurement, 1968, 28, 493–502) and the Mandler and Sarason (Journal of Abnormal and Social Psychology, 1952, 47, 166–173) Test Anxiety Questionnaire. Contingent instructions, in which Ss were told success on a test was necessary to qualify for opportunities to succeed on subsequent tests, were contrasted to performance in equivalent noncontingent situations and relative to adjusted achievement motivation for both male and female subjects. In noncontingent situations Ss were told performance on any one test did not affect their opportunity to take subsequent tests. Support was obtained for the use of the above mentioned scales as a predictor of performance for both sexes but not for the Mehrabian by itself. Both male and female Ss high in achievement motivation consistently scored significantly higher than Ss low in achievement motivation in all conditions. The expected interactions between treatments and motive groups were not found but t tests between extreme motive groups within conditions revealed significant differences in the expected directions. These results do not provide statistically reliable support to the elaborated theory of achievement motivation.     

Can Muslims Befriend Non-Muslims? Debating al-walāʾ wa-al-barāʾ (Loyalty and Disavowal) in Theory and Practice

This article analyzes the polemic on the concept of al-walā? wa-al-barā? (commonly translated as “loyalty and disavowal”). While existing academic literature focuses on the usages of this concept by jihad activists, the article centers on the role “loyalty and disavowal” plays in debates between contemporary salafī and wasa?ī jurists and theologians, specifically in their conflicting agendas for Muslims living as minorities. Salafīs, relying on several qur'anic verses and Prophetic traditions, promote an understanding of “loyalty and disavowal” that requires Muslims to refrain from befriending or loving non-Muslims, or imitating their beliefs and customs. Relying on counter-verses and traditions, in particular Q 60.8, wasa?īs have interpreted the concept of “loyalty and disavowal” more narrowly, arguing that it applies only to non-Muslims who fight against Muslims; as part of their integration-oriented doctrine for Muslims in the West, they have in recent years dedicated considerable efforts to refuting the salafī interpretation of al-walā? wa-al-barā?. The article examines the juristic methodologies utilized in the debate, and how it has affected religious decisions (fatwās) on Islamic life in Western societies.
