high-resolution electron microscopy at a (113) symmetric Thermally activated step motion observed by tilt grain-boundary in aluminium

Grain-boundary migration is demonstrated to proceed by lateral propagation of a small step in a (113), [110] symmetric Al tilt grain-boundary. In-situ high-resolution (transmission) electron microscopy (HREM) at 523K allowed the study of atomic-scale detail at video rates during the migration process. The grain-boundary translational states on both sides of the step are identical, which leads to a step dislocation. This defect can move laterally by a combination of climb and glide. Dynamic HREM images indicate considerable atomic agitation within the dislocation core. A detailed temporal analysis of the step movements shows small random displacements of the dislocation core.     

Discriminating Against “Organ Takers”

This paper offers an exposition of what the question of method in ethics consultation involves under two conditions: when ethics consultation is regarded as a practice and when the question of method is treated systematically. It discusses the concept of the practice and the importance of rules in constituting the actions, cognition, and perceptions of practitioners. The main body of the paper focuses on three elements of the question of method: canon, discipline, and history, which are treated heuristically to outline what the question of method in ethics consultation fully involves.     

Aggression in the Laboratory: Problems with the Validity of the Modified Taylor Competitive Reaction Time Test as a Measure of Aggression in Media Violence Studies

Many laboratory studies of aggression use a measure known as the modified Taylor Competitive Reaction Time Test (TCRTT), for which validation studies are lacking. Using sound blasts administered by the participant against a fictional human opponent, the TCRTT also allows for multiple methods of measuring aggression. The validity of the TCRTT was tested in 53 college student participants. Participants took a self-report measure of aggressiveness as well as neuropsychological measures of frontal lobe functioning predictive of aggression. Results were not supportive of the TCRTT's validity and indicated concerns regarding the use of the TCRTT as a measure of aggression. Results suggest that labaratory studies of media violence using the TCRTT are of questionable validity.     

Certainty and Uncertainty: The Two Faces of the Hindsight Bias

“Hindsight Bias” is a person's tendency, after learning about the actual outcome of a situation or the correct answer to a question, to distort a previous judgment in the direction of this new information. In the literature, hindsight bias has been mostly discussed as an inevitable result of a “judgment under uncertainty.” We think that the hindsight bias is due to memorial as well as inferential processes: Whereas certainty about the recollection is memorial and concerns the recollective experience, certainty at the time of the judgment is inferential and concerns the individual's metaknowledge (“I know that I knew that”). In two experiments participants' feelings of certainty were measured indirectly (Koriat & Goldsmith, 1996) by giving participants the option of leaving those questions unanswered about which they felt uncertain. This free-report option was offered to half of the participants in the first estimate phase (concerning time of judgment) and to the second half in the memory phase (concerning the recollective experience). At the end of the session, participants were presented again with the questions they had skipped and were now required to answer them. This procedure allowed us to compare the amount of hindsight bias for the skipped, uncertain items to the spontaneously answered, certain ones. Both experiments demonstrated that the hindsight bias is a result of the interaction of both uncertainty and certainty.

Cross‐cultural Generalizability of the Alternative Five‐factor Model Using the Zuckerman–Kuhlman–Aluja Personality Questionnaire

Several personality models are known for being replicable across cultures, such as the Five‐Factor Model (FFM) or Eysenck's Psychoticism–Extraversion–Neuroticism (PEN) model, and are for this reason considered universal. The aim of the current study was to evaluate the cross‐cultural replicability of the recently revised Alternative FFM (AFFM). A total of 15 048 participants from 23 cultures completed the Zuckerman–Kuhlman–Aluja Personality Questionnaire (ZKA‐PQ) aimed at assessing personality according to this revised AFFM. Internal consistencies, gender differences and correlations with age were similar across cultures for all five factors and facet scales. The AFFM structure was very similar across samples and can be considered as highly replicable with total congruence coefficients ranging from .94 to .99. Measurement invariance across cultures was assessed using multi‐group confirmatory factor analyses, and each higher‐order personality factor did reach configural and metric invariance. Scalar invariance was never reached, which implies that culture‐specific norms should be considered. The underlying structure of the ZKA‐PQ replicates well across cultures, suggesting that this questionnaire can be used in a large diversity of cultures and that the AFFM might be as universal as the FFM or the PEN model. This suggests that more research is needed to identify and define an integrative framework underlying these personality models. Copyright © 2016 European Association of Personality Psychology     

The Modern Religious Language of Education: Rousseau’s Emile

The Republican education, its concepts, theories, and form of discourse belong to the shared European heritage of the pre-modern Age. The pedagogy of humanism and its effects on the early Modern Age are represented by Republicanism. Even if Republicanism found a political continuation in liberalism and democratism of the Modern Age, the same cannot be said of pedagogic continuity without some reservations. In pedagogy of the Modern Age an alternative to Republicanism prevails that builds onto a body of concepts, discourse, and theory; it goes back to an old theological tradition. Rousseau chooses this alternative exclusively for his concepts of education. He is neither the inventor nor the one who builds up this language in contrast to pedagogical Republicanism. Nonetheless, the pedagogical canonization of Rousseau as one of the co-founders of pedagogical Modernity, marks the specific development that this theological language of pedagogy undergoes at the turn of the nineteenth century. Originally it is closely linked to specific theological, dogmatic lines of thought, namely, to the respective Piety movements within the two Christian denominations of Western Europe. Yet at the turn of the nineteenth century, this theological language of pedagogy increasingly loses that exclusive link to this particular context and becomes thus freely available to any form of pedagogy, which puts at its centre the child??s soul, absolute inwardness, and introspection as both holy and also threatened by a basically decadent social environment and outward world.     

Gender and leadership aspiration: Interpersonal and collective elements of cooperative climate differentially influence women and men

Female leaders remain a minority. Because leadership aspiration is a predictor of advancement, understanding stimulating conditions is important. A neglected perspective is the impact of organizational climate. We propose that cooperative climate can engender individuals’ motivation to contribute to the organization through leadership, and that leadership aspiration of women and men is differentially sensitive to interpersonal and collective aspects of cooperative climate. We argue that women are more disposed toward relational self‐construal and men toward collective self‐construal, and hence women's leadership aspiration is more influenced by the interpersonal element of cooperative climate whereas men's leadership aspiration by the collective element of cooperative climate. Results of a survey of N = 404 employed men and women supported both hypotheses.     

Strategies for learning proper names: expanding retrieval practice,meaning and imagery

Name learning strategies including retrieval practice, semantic associations and imagery were compared in laboratory‐based and real‐life experiments. Experiments 1 and 2 studied expanding retrieval practice and a semantic association strategy as memory improvement techniques for learning proper names. Participants either retrieved or restudied names on the same, expanding schedule. After a short, filled interval, cued recall of names was about 250% better following retrieval than restudy and 200% better with than without semantic associations. Together, the techniques improved recall by 300–400%. In Experiment 3, retrieval practice was compared with an imagery mnemonic for name learning under real‐life social conditions: Participants sought to learn the names of people they met at a party. Retrieval practice produced 50% higher recall after 24–72 hours but the imagery mnemonic was no more effective than non‐directed instructions to learn names.

Realism Despite Cognitive Antireductionism

Building on previous work, I continue the arguments for scientific realism in the presence of a natural level structure of science. That structure results from a cognitive antireductionism that calls for the retention of mature theories even though they have been “superseded”. The level structure is based on “scientific truth” characterized by a theory's validity domain and the confirming empirical data. Reductionism (including fundamentalism) fails cognitively because of qualitative differences in the ontology and semantics of successive theories. This cognitive failure exists in spite of the mathematical success of theory reduction. The claim for scientific realism is strongly based on theory coherence between theories on adjacent levels. Level coherence consists of mathematical relations between levels, as well as of reductive explanations. The latter refers to questions that can be posed (but not answered) on a superseded level, but which can be answered (explained) on the superseding level. In view of the pluralism generated by cognitive antireductionism, theory coherence is claimed to be so compelling that it provides strong epistemic justification for a pluralistic scientific realism.
