Model selection and Akaike's Information Criterion (AIC): The general theory and its analytical extensions

During the last fifteen years, Akaike's entropy-based Information Criterion (AIC) has had a fundamental impact in statistical model evaluation problems. This paper studies the general theory of the AIC procedure and provides its analytical extensions in two ways without violating Akaike's main principles. These extensions make AIC asymptotically consistent and penalize overparameterization more stringently to pick only the simplest of the “true” models. These selection criteria are called CAIC and CAICF. Asymptotic properties of AIC and its extensions are investigated, and empirical performances of these criteria are studied in choosing the correct degree of a polynomial model in two different Monte Carlo experiments under different conditions.     

THE RELIGIOUS DIMENSIONS OF THE BIOLOGICAL NARRATIVE

Abstract. A cell/molecular biologist challenges the thesis that science and religion are two ways of experiencing and interpreting the world and explores instead the possible ways that the modern biological worldview might serve as a resource for religious perspectives. Three concepts—meaning, valuation, and purpose—are argued to be central to the entire biological enterprise, and the continuation of this enterprise is regarded as a sacred religious trust.     

Management Selection in Australia: A Comparison with British and French Findings

The present study provided data on the cross-national use of management selection methods by collecting information from the Australian context. The data is compared with the British and French findings obtained by Shackleton and Newell (1991). A total of 254 companies (53.4%) responded to the survey. The overall pattern of results indicated that Australian management selection methods were closer to the British than to the French findings. Compared to previous Australian studies, the present data indicated that the main selection tools being used are unchanged. Some evidence was found that selection methods may differ within organizations comprising the private sector and between the private and public sector. The business sector made significantly greater use of cognitive testing and assessment centres compared to manufacturing, retail and government sectors. The government sector reported a significant difference in using two or three interviewers. It is proposed that, although surveys of this type have been useful as general reviews of the area, future research would benefit by collecting: (1) data on the specific measures used, (2) distinguishing between internal and external recruitment, (3) distinguishing between private and public sector recruitment, and (4) ensuring respondents have the same conceptual understanding of the selection methods covered by the survey.     

European Management Selection Methods: A Comparison of Five Countries

There is some disagreement in the recent literature on how similar or different are the methods used to select employees in different European countries. The confusion comes about in part because different samples and questions have been used in different countries to investigate this issue, making comparison between countries very difficult. This study investigates managerial selection methods in three members of the European Community, Belgium, Germany and Italy, using the same questionnaire and sample characteristics previously used in Britain and France. This allows a direct comparison between the five countries. The samples comprised 250 companies randomly drawn from the top 1,000 in each country. Questionnaires sent to the companies asked a range of questions concerning the frequency of use of selection methods and attitudes towards their use. Results show major differences in frequency of use of different methods. Some of these differences are: British and German companies tend to use assessment centres much more often than other countries, while Germany and Italy are relatively infrequent users of psychological tests. Companies in the Flemish (Dutch speaking) part of Belgium are the most likely to use biodata, while their French speaking compatriots are similar to the French in their liking for graphology. Both Belgium and France make much less use of references than do Britain, Germany and Italy. Results suggest that harmonization of selection practice in Europe is a long way off. Habit, tradition and culture determine the choice of selection method much more than do the relative predictive validities of the techniques.     

Minimizing subject loss in a longitudinal study of deviant behavior

A number of techniques are described to prevent attrition of four different categories of subjects in a longitudinal study of deviant behavior.Difficult to schedule subjects required persistence, empathy and flexibility to ensure their continued participation.Reluctant subjects were persuaded to participate by taking special care to build rapport with that family.Subjects who initially refused were turned around by assuming that a subject's refusal one year was circumstantial, and approaching that subject the following year with personalized correspondence that emphasized the importance of their contribution to the research. Persistence was an important factor in successfully locating and recruitingtransient subjects.     

Exploratory Factor Analysis: A Users’Guide

In 1978, Comrey wrote a guide to factor analysis in the Journal of Consulting and Clinical Psychology. This paper provides an update of the information given by Comrey in relation to exploratory factor analysis (EFA) for work and organizational psychologists, and particularly those involved with test development, interpretation and validation. In doing so, it offers a user's guide to contemporary methods and available techniques and introduces heuristics for dealing with problems of skew and kurtosis, social desirability response set, and factor naming.     

RELIGION AND CULTURAL EVOLUTION

Abstract. The end of the twentieth century marks the slow disintegration of both the Marxist and capitalist socioeconomic theories, inasmuch as both have proven inadequate to meet basic issues of human existence. Their inadequacy rests on the tendency to use the criteria of extrinsic rewards, quantification, production, and consumption to evaluate human personhood and human activity. What is needed is a third alternative to these two systems, one that is based on intrinsic rewards and cultivates internal values rather than production, consumption, and quantification. Religious communities have traditionally been such an alternative and seem to represent an ordered nucleus of information that can counter the inadequacies of Marxism and capitalism. To carry out this function, religions must (1) minimize the trivial differences that set belief systems against one another; (2) support bimodal cultural evolution that allows the old and the new to coexist; and (3) discover the unifying factors that cut across human groups.     

CONSCIOUSNESS FOR THE TWENTY-FIRST CENTURY

Abstract. Human action and experience are the outcome of genes and memes. Not only are both of these represented in consciousness, but consciousness mediates their claims and thus governs our choices. Hence it is important how consciousness is ordered and where it is directed. Sorokin's typology of the sensate and the ideational ("spiritual"), and the dialectic between them, is relevant to this issue. In our period of history, the sensate factors of materialism and secularism need to be dialectically counterbalanced by the reinforcement of memes that value the spiritual intimations of the realm beyond the senses. As we approach the twenty-first century, the memes that will undergird our spirituality will be those that resacralize nature and emphasize our unity as humans with all of universal reality, in an idea of common "beinghood." Spiritual systems that accord with this trend in evolution will have to respect three conditions. They will (1) integrate the sensate and the ideational; (2) reflect the importance of the "flow" state of optimal experience, which matches ever-complexifying skills with comparable challenges; and (3) move the fulcrum of their worldview from the human being to the network of beings and its evolution.     

The biasing effects of selection and attrition on estimating the mean

Organizational and validation researchers often work with data that has been subjected to selection on the predictor and attrition on the criterion. These researchers often use the data observed under these conditions to estimate either the predictor or criterion's restricted population means. We show that the restricted means due to direct or indirect selection are a function of the population means plus the selection ratios. Thus, any difference between selected mean groups reflects the population difference plus the selection ratio difference. When there is also attrition on the criterion, the estimation of group differences becomes even more complicated. The effect of selection and attrition induces measurement bias when estimating the restricted population mean of either the predictor or criterion. A sample mean observed under selection and attrition does not estimate either the population mean or the restricted population mean. We propose several procedures under normality that yield unbiased estimates of the mean. The procedures focus on correcting the effects of selection and attrition. Each procedure was evaluated with a Monte Carlo simulation to ascertain its strengths and weaknesses. Given appropriate sample size and conditions, we show that these procedures yield unbiased estimators of the restricted and unrestricted population means for both predictor and criterion. We also show how our findings have implications for replicating selected group differences.     

Called to repair injustice: Connecting everyday practices to societal phenomena,creating momentum for solidarity and change

I have been working with a model of witnessing for more than 30 years (Weingarten, 2000a). In this article, I add layers to its conceptualization by discussing several related concepts: the implicated subject (Rothberg, 2019) and ethical loneliness (Stauffer, 2015) among them. What distinguishes the Witnessing Model positions from the implicated subject is that the implicated subject is always aligned with power and/or domination, whereas a witness may not be. Certain responsibilities accrue if we take our implication seriously. Just as I have suggested there are steps one can take from positions two, three and four of the Witnessing Model to enter, return or remain in the aware and empowered position, a position from within which accountability is more likely, I offer ideas about how one can respond accountably when one acknowledges one's implication. Throughout this article, I raise questions, some of which I cannot answer. For instance, can empathic repair be undertaken by one party to a ruptured relationship, one segment of a society, without an unfolding process of mutual recognition and compassion? The contemporary moment in which we are living presents us with dire outcomes if the answer is “no.” The entire article is an extended meditation on the following central question: How can we, implicated subjects, practice solidarity to diminish ethical loneliness and create movement toward the personal, interpersonal and structural changes necessary to address the truths that our implication entails?
