Semiquantitative analysis of surface relief due to martensite formation in Fe-Mn-Si-based shape memory alloys by atomic force microscopy

Semiquantitative analysis of the surface relief caused by martensite formation in Fe-Mn-Si-based shape memory alloys has been performed by atomic force microscopy. It is found, for the thermally induced martensite transformation, that all three possible variants of martensite with the same {111} habit plane appear while, for the stress-induced martensite transformation, only one martensite variant is likely to form. For the former case, martensite plates with various variants are formed on the same habit plane in such a way that the shape strains of those plates are self-accommodated macroscopically, but each martensite plate itself is a single variant and not a multivariant plate as has been reported in the literature. For the latter case, it is especially emphasized that all the martensite plates formed in the well 'trained' sample have the same variant, which is one of the most important conditions for exhibiting a good shape memory effect.     

A new type of defect on {1120} planes in ß-Si3N4 produced by neutron irradiation

Measurements of static permittivity, refractive index and density have been carried out to study possible H-bonded complexes in solutions of anisole diluted by benzene together with high-static-permittivity alcohols, i.e. cyclohexanol, n-butanol, tert-butanol, isopropyl alcohol and 1-hexanol. The experiments were performed at 303 K. Dipole moments of the mixtures are calculated from the experimental data and these are used to obtain dipolar increments. The concentration ratio of proton donor to proton acceptor is plotted against a parameter, Ω_B, which is determined from experimental data. From the plot, the dipole moment of the mixture and that of the component B are determined. The order of the complex can be obtained from the nature of the graph. The investigation shows that the interaction between the two components arises solely from a polarization effect.     

Giant electrocaloric effect of highly (1 0 0)-oriented 0.68PbMg1/3Nb2/3O3–0.32PbTiO3 thin film

PbZr_0.95Ti_0.05O₃ thin film has the highest electrocaloric properties of all the oxide thin films (0.48?K?V^?1). Here, it is shown giant electrocaloric properties in 200?nm (1?0?0)-oriented PMN–PT 68/32 film near the ferroelectric Curie temperature of 146?°C. The results indicate the significance of this system to achieve electrocaloric entropy change and temperature change, up to 32.21?J/kg?°C and 14?K, respectively, in 12?V (i.e. 1.155?K?V^?1) near the Curie point. This exceeds the previous best results obtained in PbZr_0.95Ti_0.05O₃ thin film.     

Psychoanalysis is a two‐way street

The paper discusses psychoanalysis as a mutual exchange between the analyst and analysand. A number of questions are raised: What was Ferenczi's and the early psychoanalysts' contribution to the interpersonal relational dynamics of psychoanalytic treatment? Why did countertransference become an indispensable tool in relationship‐based psychoanalysis? Why is the transference‐countertransference dynamic seen as a special dialogue between the analyst and analysand? What was Ferenczi's paradigm shift in the trauma theory? How did he combine the object relation approach with Freud's original trauma theory? The paper illustrates through some case study vignettes the intersubjective and intrapsychic dynamic in the process of traumatization. We can look at countertransference as an indicator of the patient's basic interpersonal experiences and traumas. Finally the paper discusses countertransference in the light of attachment theory, connecting the early initiatives of inter‐relational approaches in psychoanalysis with recent research.     

Reinstatement of odour context cues veridical memories but not false memories

ABSTRACT

The sense of smell has made a recent return to the forefront of research on episodic memory. Odour context cues can reactivate recently encoded memories during sleep-dependent memory consolidation [e.g., Rasch, B., Buchel, C., Gais, S., & Born, J. (2007). Odor cues during slow-wave sleep prompt declarative memory consolidation. Science, 315, 1426–1429], and reinstating the odour experienced during encoding at test results in superior recall and recognition [e.g., Isarida, T., Sakai, T., Kubota, T., Koga, M., Katayama, Y., & Isarida, T. K. (2014). Odor-context effects in free recall after a short retention interval: A new methodology for controlling adaptation. Memory & Cognition, 42, 421–433]. However, whether the impact of odour cues is restricted to the specific memories studied in the presence of the odour, or whether reinstating the odour also cues unstudied memories that are semantically related to the studied memories (i.e., false memories) is unknown. We used the Deese-Roediger-McDermott false memory paradigm to quantify the impact of odour cues on both veridical memory and false memory. Reinstating the odour presented during the study of the DRM word lists at the test phase resulted in better free recall of the studied words, but had no statistically significant impact on the number of false memories produced. We argue that odour cues influence recall of the memories they co-occurred with during study but potentially not semantically related memories.     

Spatial Conceptions in Chinese and Canadian Children

Four-, five-, and six-year-old Chinese and Canadian boys and girls were presented a series of 11 graphic models and were asked to draw them. Supporting Piaget's theory, the data indicated that drawing performance on the topological dimension was better than the performance on the Euclidean dimension, and that there were neither gender nor cultural differences in performance. The research offers strong support for a main effect of biological or maturational factors as the foundation for the developmental influences in the acquisition of spatial conceptions.     

On the persuadability of memory: Is changing people's memories no more than changing their minds?

The observation of parallels between the memory distortion and persuasion literatures leads, quite logically, to the appealing notion that people can be ‘persuaded’ to change their memories. Indeed, numerous studies show that memory can be influenced and distorted by a variety of persuasive tactics, and the theoretical accounts commonly used by researchers to explain episodic and autobiographical memory distortion phenomena can generally predict and explain these persuasion effects. Yet, despite these empirical and theoretical overlaps, explicit reference to persuasion and attitude‐change research in the memory distortion literature is surprisingly rare. In this paper, we argue that stronger theoretical foundations are needed to draw the memory distortion and persuasion literatures together in a productive direction. We reason that theoretical approaches to remembering that distinguish (false) beliefs in the occurrence of events from (false) memories of those events – compatible with a source monitoring approach – would be beneficial to this end. Such approaches, we argue, would provide a stronger platform to use persuasion findings to enhance the psychological understanding of memory distortion.     

The Effects of Dysphoria and Personality on Negative Self-Referent Attitudes and Perceptions of the Attitudes of Others

The cognitive model of depression posits that depressed individuals harbor more dysfunctional self-referent attitudes, but little is known about how depressed individuals perceive the attitudes and perceptions of others in their social arena. This study examined whether dysphoric individuals perceive others to hold equally negative attitudes about themselves, and whether such perceptions depend on sociotropic (i.e., highly invested in social approval and relationship success) and autonomous (i.e., highly invested in vocational or academic achievement and goal attainment) personality styles. A sample of undergraduate students (N = 197) was recruited, and after the assessment of their depression symptoms and personality style, participants read vignettes that described negative scenarios, and imagined that these scenarios occurred to themselves or the general university student. After reading each vignette, participants also rated their agreement with a number of statements that assessed dysfunctional attitudes. Results indicated that elevated dysphoria (i.e., showing signs of depression) scores were positively associated with dysfunctional self-referent attitudes. Further, moderational analyses examining the interaction of sociotropy and dysphoria did not support the hypothesis that individuals higher on dysphoria and sociotropy were less likely to perceive others as harboring negative attitudes about themselves in comparison to those with elevated dysphoria and lower levels of sociotropy. Last, individuals showing elevated dysphoria and higher scores on subdomains of autonomy were more likely to perceive others as exhibiting negative attitudes about themselves than those with low levels of the trait. These findings, their implications, and strengths and limitations of the current investigation are further discussed.     

Young children produce categorical false recall without activation of the lure items

Individuals who study a list of words that are all related to another word that is not presented (a lure word) sometimes produce a false memory of having studied the lure word. The false memories are observed in lists of words that are in the same category as (category list) or associated with (associative list) a word that was not presented in an attempt to elicit false recall. The present study investigated whether young children create these types of false recall. Following the study of a categorical list, false recall was elicited in young children to the same degree as in adults, but studying an associative list elicited false recall only in adults. Furthermore, categorically related lure words did not have a priming effect in young children. These results suggest that the categorical false recall is produced via a different mechanism from the associative false recall.
