Aqua vitae,aqua permanens: dreaming,drowning, swimming and surfing in analysis

In response to the question ‘Who is My Jung?’, this paper describes the profound personal impact of Jung's creative / artistic approach to the unconscious, beginning with my discovery of The Red Book at the age of twelve. Echoing the flow of my own dream‐life, I trace the course of two analyses through the alchemical process of solutio, which began with numinous dreams of tidal waves and plunged us into inter‐ and intra‐psychic analytic relationships that evoked vestigial memories of our first aquatic world in utero.     

An analytical solution to the nonlinear evolutionary equations for nucleation and growth of particles

ABSTRACT

In this paper, we consider a mathematical model for the growing crystals in supersaturated or supercooled systems. An integro-differential equation of the Fokker-Planck type is analytically solved using the saddle point method for the Laplace integral. The solution describes an intermediate stage of the phase transition process with allowance for the power law of the growth rate of spherical particles and the nucleation mechanisms known as the Meirs and Weber-Volmer-Frenkel-Zeldovich kinetics. A dynamical dependencies for the supersaturation/supercooling and the distribution function of crystals by their size are obtained. The novelty of the theory is the use of a power law for the growth rate of crystals, which leads to new analytical solutions of the problem.     

Temperature dependence of nucleation rate in a binary solid solution

The influence of regression (partial dissolution) effects on the temperature dependence of nucleation rate in a binary solid solution has been studied theoretically. The results of the analysis are compared with the predictions of the simplest Volmer–Weber theory. Regression effects are shown to have a strong influence on the shape of the curve of nucleation rate versus temperature. The temperature T_M at which the maximum rate of nucleation occurs is found to be lowered, particularly for low interfacial energy (coherent precipitation) and high-mobility species (e.g. interstitial atoms).     

Single-Letter Retrieval Cues for Anagram Solution

Anagram solution, as related to single-letter retrieval cues and first letter of the solution word (consonant or vowel), was examined. In Experiment 1, college-aged solvers were presented both types of 5-letter words and either the first letter of the solution word as a cue, or no cue. In Experiment 2, the effects of four types of retrieval cues (first, middle, or last letter or no cue) upon solving consonant-beginning words was examined. Finally, Experiment 3 examined the solution of both types of solution words as related to the preceding four types of retrieval cues. The results of all 3 experiments showed that a single letter can be an effective cue. For consonant-beginning words, the middle and last letters were as effective as the first letter. For vowel-beginning words, the first letter was more effective than either the middle or last letter. It was concluded that solvers select one letter of the anagram, typically a consonant, to serve as the first letter of the solution word, and then rearrange the remaining letters.     

Trade‐off ranking method for multi‐criteria decision analysis

Multi‐criteria decision analysis presumes trade‐off between different criteria. As a result, the optimal solution is not unique and can be represented by the Pareto frontier in the objective space. Each Pareto solution is a compromise between different objectives. Despite a limited number of Pareto optimal solutions, the decision‐maker eventually has to choose only one option. Such a choice has to be made with the use of additional preferences not included in the original formulation of the optimization problem. The paper represents a new approach to an automatic ranking that can help the decision‐maker. In contrast to the other methodologies, the proposed method is based on the minimization of trade‐off between different Pareto solutions. To be realized, the approach presumes the existence of a well‐distributed Pareto set representing the entire Pareto frontier. In the paper, such a set is generated with the use of the directed search domain algorithm. The method is applied to a number of test cases and compared against two existing alternative approaches.     

A one-step method for modelling longitudinal data with differential equations

Differential equation models are frequently used to describe non-linear trajectories of longitudinal data. This study proposes a new approach to estimate the parameters in differential equation models. Instead of estimating derivatives from the observed data first and then fitting a differential equation to the derivatives, our new approach directly fits the analytic solution of a differential equation to the observed data, and therefore simplifies the procedure and avoids bias from derivative estimations. A simulation study indicates that the analytic solutions of differential equations (ASDE) approach obtains unbiased estimates of parameters and their standard errors. Compared with other approaches that estimate derivatives first, ASDE has smaller standard error, larger statistical power and accurate Type I error. Although ASDE obtains biased estimation when the system has sudden phase change, the bias is not serious and a solution is also provided to solve the phase problem. The ASDE method is illustrated and applied to a two-week study on consumers’ shopping behaviour after a sale promotion, and to a set of public data tracking participants’ grammatical facial expression in sign language. R codes for ASDE, recommendations for sample size and starting values are provided. Limitations and several possible expansions of ASDE are also discussed.     

The robustness of the factor structure of the Self-Restraint Scale: What does self-restraint encompass?

In contrast with the original version of the Self-Restraint Scale (SRS; [Weinberger, D.A., & Schwartz, G.E. (1990). Distress and restraint as superordinate dimensions of self-reported adjustment: A typological perspective. Journal of Personality, 58, 381–417]), confirmatory factor analysis did not support a four-factor solution. In the current study an exploratory factor analysis revealed a three-factor structure. Although the original subscales suppression of aggression, consideration of others, and impulse control were confirmed by the data, responsibility did not fit within the overall concept of self-restraint. These results provide some indication that although the subscales can be used independently, the way self-restraint is conceptualized should be reconsidered. Future studies are needed to confirm the factor structure observed in the current study.     

小学数学真实性问题解决的调查研究

在常规课堂上对来自北京市两所小学148位10-12岁的小学生进行真实性问题的测验,研究结果表明:1)被试中对真实数学问题作出真实性解答的人数比例约为四分之一,高于国外同类研究中比例.2)作出常规解答的人数比例约为一半,显著高于作出真实解答的人数比例.3)六年级被试作出真实解答的人数比例普遍高于四年级,但是在某些问题上,六年级被试中作出常规解答的人数比例反而高于四年级.4)被试对不同真实问题的反应存在一定的差异,这可能与真实问题的特点有关.     

Penser autrement les difficultés scolaires : les apports du Rorschach en système intégré

This study examines school under-achievement from the perspective of clinical psychology. We compare 2 groups of children in the 3^rd grade (mean age 9) based on their results on a national test of French language and Mathematics. We present the Rorschach results of 7 high performers compared to 7 low performers, all of whom have IQ scores (K. ABC) that are in the average range (90 - 109). The Rorschach data (Comprehensive System) demonstrate no differences between these groups of children concerning affective functioning and stress tolerance. However, the quantitative and qualitative results are notably different concerning attitudes relative to complex situations, in the area of critical self-perception and conflict-resolution strategies.
