Pairwise agreement of gradient directions in interactive multicriterion optimization

Statistical tests involving mean directions have in the past been limited to two- and three-dimensional settings, perhaps owing to their primary applications to such fields as geology, meteorology and related earth sciences. In the study of interactive multicriterion optimization it becomes necessary to compare gradient directions obtained from decision makers by two or more methods. Typically these direction vectors are in a higher-dimensional space. This paper provides a general procedure based on Householder transformations which is potentially suitable for any finite dimension. An illustration and comparison of the method are provided.     

Identity practices, ingroup projection, and the evaluation of subgroups: a study among Turkish-Dutch Sunnis

This research focuses on religious subgroup evaluations by examining the attitude of Turkish-Dutch Sunni Muslims towards Alevi and Shiite Muslims. Following the Ingroup Projection Model, it was expected that Sunni participants who practice Islam will project their self-defining subgroup practices on the superordinate Muslim category, which will be related to more ingroup bias towards Alevis, a Muslim subgroup that performs different religious practices. Two studies yielded consistent evidence that practicing Islam increased ingroup bias towards Alevis. Furthermore, in Study 2, we found evidence that the effect of practicing Islam on ingroup bias was mediated by relative ingroup prototypicality (RIP). Moreover, practicing Islam did not affect RIP in relation to Shiites who perform the same religious practices that we examined. These findings support the Ingroup Projection Model.     

The ‘workshy’

Abstract

This article is an attempt to apply the Kleinian ‘positions’ to long-term unemployment and to use them to suggest an alternative to punitive concepts such as ‘workshy’, while discussing the paradox in which a sincere attempt to find work exists alongside behaviour which seems designed to sabotage it. Such sabotaging behaviour not only offers secondary gains but affords channels for projections which mitigate unresolved aggression. While effective in coping with long-term unemployment, these mechanisms inhibit development and ‘benign cycles’ are gridlocked. Change and growth are seen as threats and aggression cannot be worked through and must be projected. Persecutory anxieties and a lack of enrichment by ‘otherness’ results and is reinforced by the reality of chronic unemployment. No opportunity for reparative work exists, so ‘concern’ and a sense of responsibility are inhibited. Narcissistic omnipotence and grandiosity is a feature. Long-term unemployment and homelessness show similar revolving door patterns connected to similar coping mechanisms.     

THE FATE OF AGGRESSION IN MASO‐MASOCHISTIC RELATIONSHIPS

This paper examines an underexplored dimension of interpersonal relating: the relationship formed between two individuals who relate to each other in masochistic ways. The common assumption is that a sadist forms an alliance with a masochist, and that a balance is struck between an individual who is “one up” and another who is “one down.” However, relationships are frequently established between two people who both experience themselves as chronically “one down,” each playing victim to the other's aggression. This paper explores disavowed aggression in this type of couple, the implications of this disavowal for treatment, and the sadomasochistic reverberations within the therapist.     

‘Who is my Jung?’ The progressive,though sometimes ambivalent,expansion of Jung's idea of the collective unconscious: from an ‘unconscious humanity’ to – in all but name – the soul of the world

This paper discusses Jung's idea of myth as a projection of the collective unconscious, suggesting that the term ‘projection’ separates human beings from nature, withdrawing nature's life into humanity. Jung's discovery of a realm independent of consciousness – in conversations with his soul in The Red Book, and in synchronicity, began a dialogue which finally brought him, through the Alchemical Mercurius, closer to the idea of a world‐soul.     

Correlating the internal length in strain gradient plasticity theory with the microstructure of material

The internal length is the governing parameter in strain gradient theories which among other things have been used successfully to interpret size effects at the microscale. Physically, the internal length is supposed to be related with the microstructure of the material and evolves during the deformation. Based on Taylor hardening law, we propose a power-law relationship to describe the evolution of the variable internal length with strain. Then, the classical Fleck–Hutchinson strain gradient theory is extended with a strain-dependent internal length, and the generalized Fleck–Hutchinson theory is confirmed here, by comparing our model predictions to recent experimental data on tension and torsion of thin wires with varying diameter and grain size. Our work suggests that the internal length is a configuration-dependent parameter, closely related to dislocation characteristics and grain size, as well as sample geometry when this affects either the underlying microstructure or the ductility of the material.     

Mechanism of formation of aligned two-phase microstructure in a Fe-0.25wt%C alloy under high magnetic field gradients

The effect of a magnetic force on creating an aligned two-phase microstructure in a Fe-0.25wt%C alloy under magnetic field gradients has been investigated. Through the changes in the heating temperature, both dipolar interactions and magnetic forces work together during the austenite to ferrite transformation. The results showed that the aligned two-phase microstructure is not observed under the influence of the magnetic force alone. The ferrite grains are elongated due to dipole interactions at the early stages of their nucleation and growth and then the magnetic force turns the elongated ferrite grains, whose major axis is not parallel to the direction of magnetic force, to the direction of the field in the presence of magnetic field gradients.     

Empathic forecasting: How do we predict other people's feelings?

When making affective forecasts, people commit the impact bias. They overestimate the impact an emotional event has on their affective experience. In three studies we show that people also commit the impact bias when making empathic forecasts, affective forecasts for someone else. They overestimate the impact an emotional event has on someone else's affective experience (Study 1), they do so for friends and strangers (Study 2), and they do so when other sources of information are available (Study 3). Empathic forecasting accuracy, the correlation between one person's empathic forecast and another person's actual affective experience, was lower than between-person forecasting correspondence, the correlation between one person's empathic forecast and another person's affective forecast. Empathic forecasts do not capture other people's actual experience very well but are similar to what other people forecast for themselves. This may enhance understanding between people.
