Anogenital distance and dominance status in male house mice (Mus domesticus)

Factors influencing the tendency to be aggressive were investigated in male house mice using a series of paired encounters. Body size, body lenght, body temperature, age, and anogenital distance were measured on all males. Paired encounters were conducted using a standard mouse cage as an arena. Across 64 males involved in 224 encounters, the tendency to be dominant and win encounters was significantly correlated only with anogenital distance (r = 0.383). These findings suggest that there are significant behavioral effects in male mice that could parallel the intrauterine position and related prental hormone effects that have been elucidated in female house mice and other rodents. © 1995 Wiley-Liss, Inc.     

Understanding the impact of heterogeneous rider preferences on a shared autonomous vehicle system

In a ride pooling system, riders may have varied behaviors in seeking pooled or non-pooled rides. It is important to understand the effect of these rider behaviors on the system performance in order to formulate policies to guide ride pooling implementation. Existing literature modeling ride pooling systems using agent-based models only considers the extreme cases in which riders either all participate or not participate in pooling. However, the pooling behaviors could be more complex. This study segments the rides in the system into five types (non-pooling only, non-pooling preferred, indifferent, pooling preferred, and pooling only). We use an agent-based model to simulate these preferences in a system of pooled autonomous vehicles. We use mixture experiments to vary the proportion of riders within these five types and build models to study the interactions among the rider types in terms of the system’s service quality and environmental performance. The results show that higher service level is achieved when all riders in the system are open to pooling, with 30% of pooling only riders and 70% of pooling preferred or indifferent riders providing the maximum value. The results can help formulate incentives and policies to promote ride pooling participation to improve ride pooling system performance.     

Symbolic conceptions: the idea of the third

The idea of the third which appears in Jung's concepts of the transcendent function and the coniunctio also occurs in several psychoanalytic theories concerning the emergence of reflective and symbolic thought in childhood development (defined here as the development of 'imaginal capacity'). Noting the way this process is often conceived in terms of the metaphor of sexual intercourse leading to 'conception', this paper suggests that such images need to be understood as symbolic conceptions of the meaning-making functions of the human mind. This leads to a different view of psychoanalytic theories that attempt to account for the development of imaginal capacity in terms of the Oedipus complex. It is suggested that a) these functions must be operative in the mind before the Oedipal situation can become meaningful and b) that psychoanalytic theories are themselves symbolic conceptions which, like mythological narratives, seek to communicate and comprehend psychic reality through imaginal forms.     

Tactile order memory: evidence for sequence learning phenomena found with other stimulus types

We examine serial order memory for sequences of tactile stimuli and investigate whether established characteristics of order memory, namely serial position effects, error distributions, and Hebb repetition learning, are observed with tactile memory. Visually obscured participants received six tactile stimulations: one to each of six fingers. At test, participants lifted the six fingers in the order of stimulation. For every third trial participants received the same order of stimulation (i.e. the Hebb sequence). Serial recall accuracy produced the canonical bowed serial position function found for immediate serial recall. In addition, recall for the Hebb sequence improved relative to the filler sequences, providing the first demonstration of the Hebb repetition effect with tactile stimuli. Analysis of errors revealed close similarities to that reported with verbal and visual stimuli. This experiment further generalises established features of order memory to tactile memory, supporting the utilisation of an analogous order memory mechanism across stimuli.     

Can this be evil? Evilness seen as intention or drive

This article was originally read as an introductory plenary paper at the German-Nordic Clinical Conference, September 2015 in Berlin. The heading of the conference was ‘On Cruelty and Destructiveness’. The paper takes as its starting point the composite figure of Dr Jekyll and Mr Hyde. It discusses the meaning of intentionality, or the lack of a conscious intention of being evil, in comparison to evil deeds caused by uninhibited drive satisfaction. Evilness is put into a social and a psycho-developmental context. Examples of contemporary atrocities are discussed, leading up to a formulation of a multi-factorial explanatory model of evil, taken from Michael Stones book ‘The Anatomy of Evil’.     

Exercises focusing on rotator cuff and scapular muscles do not improve shoulder joint position sense in healthy subjects

Proprioception is essential for shoulder neuromuscular control and shoulder stability. Exercise of the rotator cuff and scapulothoracic muscles is an important part of shoulder rehabilitation. The purpose of this study was to investigate the effect of rotator cuff and scapulothoracic muscle exercises on shoulder joint position sense. Thirty-six healthy subjects were recruited and randomly assigned into either a control or training group. The subjects in the training group received closed-chain and open-chain exercises focusing on rotator cuff and scapulothoracic muscles for four weeks. Shoulder joint position sense errors in elevation, including the humerothoracic, glenohumeral and scapulothoracic joints, was measured. After four weeks of exercise training, strength increased overall in the training group, which demonstrated the effect of exercise on the muscular system. However, the changes in shoulder joint position sense errors in any individual joint of the subjects in the training group were not different from those of the control subjects. Therefore, exercises specifically targeting individual muscles with low intensity may not be sufficient to improve shoulder joint position sense in healthy subjects. Future work is needed to further investigate which types of exercise are more effective in improving joint position sense, and the mechanisms associated with those changes.

Quand le genre s’en mêle : quelle conciliation entre vie professionnelle et vie privée ?

Declarations of conciliation between private life and professional life based on three factors (sex, gender and positions) are studied in this paper. Our goals were (i) to show that conciliation between the different life spheres need to be considered both in terms of conflict and of life enrichment; (ii) and to demonstrate that the gender variable has combined effects with sex variables, as well as with positions variables, over the perception of work in relation to family interferences in terms of nature (conflict/enrichment), intensity and direction (family over work versus work over family). The study, conducted with 240 employees of low or high professional positions, based on SWING and BSRI scales, shows the moderating effect of gender on the perceptions of conciliation, whether enriching or conflicting. Our results also allow us to conclude that congruent adjustment (masculine domination) of the levels of our three factors constitute a protecting factor for employees, while an incongruent adjustment can constitute a risk factor, this being especially verified for women.     

Mens sana in corpore sano: Psychotherapy with a cerebral palsy child aged nine months

This paper is the acount of the psychoanalytic understanding and treatment of a nine-month-old cerebral-palsy infant and her mother. When first seen, Abigail hung over her mother's arm, and would scream unceasingly if moved from this position. The mother-child relationship seemed to involve their sticking to each other without looking or losing contact. The mother's hidden hate, anger and resentment were communicated non-verbally and Abigail showed signs of finding it difficult or impossible to integrate experiences, given the amount of trauma she had suffered from an attempted abortion and the lack of enough experience of being loved to enable her to grow internally.

The process of assessing the internal world of the infant and her mother, and the thinking and planning of the psychotherapy that followed, are described. In order to promote the secure attachment of the mother-child dyad, and the emotional growth of both, the helping process focused on understanding both the baby's and mother's states in order to make sense of the child's inner world to the mother. Because of the acute pain this process involved for the mother, she was treated individually too, by a different therapist.

Abstract

There are many brief, demanding, aborted cases that no one ever writes about. The typical psychoanalyst or psychoanalytic psychotherapist, however, has many outpatient cases that are shortlived, intense encounters with very disturbed patients. Rather than ignore these encounters as non-analytic or non-instructive, I think these cases add to our knowledge about the mind and its functions. In addition, it is unrealistic to think we can always help a very anxious and disturbed person to enter the treatment process with immediate success. It is more instructive to apply the analytic method and offer the patient what we can and have both analyst and patient learn as much as they can in the time they are able to stay together. Using case material, I show the Kleinian approach to working analytically with these difficult patients. Whether focusing on transference or extra-transference material, the analyst interprets the patient's internal phantasies and anxieties regarding the self and the self's important objects. This analytic stance tends to relieve the immediate anxiety and set the stage for potential self-reflection and the start of basic working-through processes.
