Generalized bilinear models

Generalized bilinear models are presented for the statistical analysis of two-way arrays. These models combine bilinear models and generalized linear modeling, and yield a family of models that includes many existing models, as well as suggest other potentially useful ones. This approach both unifies and extends models for two-way arrays, including the ability to treat response and explanatory variables differently in the models, and the incorporation of external information about the variables directly into the analysis. A unifying framework for the generalized bilinear models is provided by considering four particular cases which have been proposed and used in the existing statistical literature. A three-step procedure is proposed to analyze data sets by generalized bilinear models. Two data sets of different nature are analyzed.     

THE NEGATIVE SIDE EFFECTS OF REWARD

The negative side effects of aversive control have been extensively discussed in clinical literature and textbooks. The symmetry between aversive and appetitive control in basic experimental research implies that parallel negative side effects of reward exist. These negative side effects are described and their implications for clinical practice and research are discussed.     

An improvement of the Harman-Fukuda-method for the minres solution in factor analysis

The method proposed by Harman and Fukuda to treat the so-called Heywood case in the minres method in factor analysis i.e., the case where the resulting communalities are greater than one, involves the frequent solution of eigenvalue problems. A simple method to treat this problem requiring less computing time and enjoying higher numerical stability is described in this paper.     

论中医的科学精神和人文方法

近十几年来中医现代化研究成效不显,以及发生许许多多的争论和困惑的重要原因在于我们对中医的基本性质缺乏一种共识。说中医就是一门科学或者不是科学,是一门经验医学或者是哲学医都会使我们陷于一个难堪的困境。中医具有科学精神,但不具有西方意义上的科学方法,而是用具有中国特色的人文方法实现科学精神的经验知识体系。具有科学精神是一回事,怎样实现这种精神却是另一回事,前者是无国界的,后者却是可以文化多元的。     

A Practical Guide to the Comparative Case Study Method in Political Psychology

The case study, as a method of inquiry, is particularly suited to the field of political psychology. Yet there is little training in political science, and even less in psychology, on how to do case study research. Furthermore, misconceptions about case studies contribute to the methodological barrier that exists within and between the two parent disciplines. This paper reviews the various definitions and uses of case studies and integrates a number of recent insights and advances into a practical guide for conducting case study research. To this end, the paper discusses various stereotypes of the case study and offers specific steps aimed at addressing these criticisms.     

A one-way random effects model for trimmed means

The random effects ANOVA model plays an important role in many psychological studies, but the usual model suffers from at least two serious problems. The first is that even under normality, violating the assumption of equal variances can have serious consequences in terms of Type I errors or significance levels, and it can affect power as well. The second and perhaps more serious concern is that even slight departures from normality can result in a substantial loss of power when testing hypotheses. Jeyaratnam and Othman (1985) proposed a method for handling unequal variances, under the assumption of normality, but no results were given on how their procedure performs when distributions are nonnormal. A secondary goal in this paper is to address this issue via simulations. As will be seen, problems arise with both Type I errors and power. Another secondary goal is to provide new simulation results on the Rust-Fligner modification of the Kruskal-Wallis test. The primary goal is to propose a generalization of the usual random effects model based on trimmed means. The resulting test of no differences among J randomly sampled groups has certain advantages in terms of Type I errors, and it can yield substantial gains in power when distributions have heavy tails and outliers. This last feature is very important in applied work because recent investigations indicate that heavy-tailed distributions are common. Included is a suggestion for a heteroscedastic Winsorized analog of the usual intraclass correlation coefficient.     

Statements of Method and Teaching: The Case of Socrates

In this paper, I ponder the question of whether Socrates follows a method of investigation — the method of hypothesis — which he advocates in Plato's Phaedo. The evidence in the dialogue suggests that he does not follow the method, which raises additional questions: If he fails to do so, why does he articulate the method? Does his statement of method affect his actions or is it mainly forgotten? Although Socrates is a fictional character, his actions in the Phaedo suggests questions about the function of espoused methods in actual situations.     

Rereading sophistical arguments: A political intervention

This essay argues that Aristotle's categories of oratory are not as useful in judging the methods of Sophistical rhetoric as his presentation of time. The Sophistical argumentative method of making the weaker the stronger case is re-evaluated as a political practice. After showing this argument's relation to power and ideology, Aristotle's philosophy, which privileges a procedure of argument consistent with the politics of a polis-ideal rhetoric, is offered as reason for objecting to Sophistical rhetoric. The essay concludes that Sophistical rhetoric prefers the concept of possibility over Aristotelian actuality, and offers a need for an ideological space of radical, generative possibility in rhetorical theory.     

The role of Improv in enhancement of Meaning in Life in youth: An explanatory sequential design

“A global mental health crisis” was sparked by the pandemic, especially for the youth as it exposed them to serious existential crises related to grief, loss, death and dying, deep psychological insecurities, etc. Additionally, this crisis came as a call for greater meaning in the personal and professional lives of youth. To deal with these issues in youth, Improv intervention is being used as an effective contemporary psychological technique to improve holistic perspective-taking. This pilot study investigated the efficacy of Improv intervention in enhancing Meaning in Life in youth using an explanatory sequential design. The sample comprised 80 youth (age range 18–25 years). The study was carried out in two phases—quantitative and qualitative. In the quantitative phase, a randomised control trial design was used to assess the efficacy of the intervention; this was followed by semistructured interviews to identify crucial themes that highlighted participants’ perceptions of Meaning in Life and the benefits of the intervention. Results revealed potential usefulness of Improv in Meaning enhancement.     

‘Liars are less detailed’ …So what? Comparing two recall instructions to detect deception within-subject

Most deception research provides between-subject results (e.g., liars give on average less detailed accounts), which might be of limited value for professionals evaluating credibility on an individual basis. This study examines the optimal instructions of a within-subject multiple recalls strategy to detect deception. A total of 110 participants, divided into a Lie and Truth group, were randomly placed into four interview conditions: two Basic report-everything instructions (1), a Basic recall followed by an Open depth instruction (2), a Basic recall followed by the Verifiability Approach and Information Protocol (3), and two recalls with the Verifiability Approach and Information Protocol (4). All recalls were coded for total details and verifiable details. Group (lie and truth) × Recall (first and second) was only significant in condition 3, with truth tellers providing more verifiable details in the second recall than the first. A simple within-subject decision rule was derived, allowing a 76.9% discrimination rate. Professionals can optimally evaluate credibility using two recalls (Basic recall followed by Verifiability Approach and Information Protocol) and observing the evolution of verifiable details.
