Orthorhombic approximant phases and their relation to quasicrystals in mechanically alloyed Al–Cu–Fe–Si alloys

The possibility of synthesis of quasicrystalline and associated approximant phases during mechanical alloying and subsequent heat treatment of Al₆₅Cu₂₀Fe₁₀Si₅ alloy powders has been investigated. It is shown that, in addition to the stable ordered quasicrystal and 1/1 cubic approximant, two more phases having orthorhombic symmetry coexist. The a and c parameters of both these phases are similar to the lattice parameters of the cubic approximant, whereas their b parameters are, respectively, three and four times larger than the c parameters. It is suggested that these phases evolve on account of local symmetry breaking of the cubic approximant phase, possibly due to ordering.     

African Americans and Teen Dating Violence

This literature review focuses on the prevalence rates of teen dating violence in the United States, emergence of dating violence research, reasons of teen dating violence in the African American community, consequences of it regarding physical and mental health, and the impact of it on psychological and physical health. The research shows a trickledown effect of racism, low socio-economic status, and growing up in poor neighborhoods leading to domestic violence in African American families, which then gets reinforced with messages received from peers and the media.     

Middle age and marriage: Affiliative men and assertive women

Abstract

This paper reviews recent literature on the psychological changes that occur in middle age in men and women which indicate that men tend to become more affiliated and women more assertive. A series of cases are presented to illustrate the impact of these changes on middle age and marriage.     

Narcissism and punitiveness in a non-ego-threatening condition

Punitiveness of overt and covert narcissists was examined in a non-ego-threatening condition. In judging fictitious criminal cases, high scorers in overt narcissism were as punitive as low scorers; this result was independent of crime severity. For covert narcissism, however, high scorers were more punitive toward a serious crime and more lenient toward a mild crime, when compared to low scorers. This study provides pioneering data on narcissists’ punitive judgments in the absence of ego threat, which has been overlooked by previous research. The findings not only support the theoretical distinction between the overt and covert subtypes of narcissism, but also help clarify the meaning of punishment to narcissists.     

Toward a Theory of Progressive Evolution (Large-Scale Stages of Evolutionary Progress)

Here I discuss the basic elements, major stages, and completion of progressive evolution. The cosmic world of self-realization is based on extensive self-development within a closed contour: temporal counter-transitions of spatial counter-elements (energy bonds and media and, basically, substance structures) form of local worlds within it through evolution of informational structures.

• The organic world of reproduction develops through the open informational path: the initial substance, through energy exchange and metabolism, reproduces similar substance; the latter interacts with the environment and, subsequently, reproduces its like, and so on.

• The animal world of self-regulation builds up a closed informational contour in the environment through the informational input and command output.

• The human world of self-cognition forms the intensive type of development within the internal closed informational contour of cognition. Counter-transitions of ideal images and signs relate to their real prototypes. In the course of cognition, abstractive thinking develops and brings man to the possibility of reflection of the initial world in its integrity (thus, elevates man to the infinite, by Hegel).

     

A process study of long-term treatment: comparing a successful and a less successful outcome

This study examined therapist technique and patient change in emotional experiencing and defense mechanisms in the successful and unsuccessful long-term psychoanalytic treatments of two male patients. Two consecutive sessions every 6 months were analyzed for each patient. Therapist interventions, patient defense mechanisms, and patient emotional experiencing were assessed using the Psychodynamic Intervention Rating Scale, Defense Mechanism Rating Scale and the Experiencing Scale, respectively. Between and within-session analyses were conducted to determine the impact of the patient’s defensive functioning and experiencing on therapist interventions, and the effect of therapist interventions on those same two patient variables. Pearson’s Coefficient was utilized for between-session analysis; within-session analysis tracking moment-to-moment changes in patient and therapist functioning was performed using lag sequential analysis. Across therapy, therapist use of Interpretive Interventions was associated with increased emotional engagement and decreased defense maturity; the use of Supportive Interventions had the opposite effect. Within-session analysis revealed that use of Supportive Interventions when emotional engagement is low, followed by interpretative interventions, occurred in the successful case. Persistent use of Supportive Interventions in the context of low emotional engagement was observed in the unsuccessful case. This study suggests that failure to stimulate emotional engagement through interpretation can negatively affect therapeutic outcome.     

The effect of working memory capacity on conflict monitoring

The conflict adaptation effect, a reduced interference effect upon the detection of a conflict signal (e.g., following an incongruent trial), has been interpreted as evidence for active regulation of top-down cognitive control. We hypothesized that the extent of conflict adaptation should be related to individuals' working memory capacity (WMC), which has been repeatedly demonstrated to reflect the level of cognitive control. Using the Simon task, in Experiment 1, we quantified the conflict adaptation ratio (CAR) transiently as the ratio of the conflict effect following an incongruent trial to the conflict effect following a congruent trial, controlling for the reaction time that often correlates with WMC. We observed that the CAR varied from highly negative with low WMC scores to near-zero with high WMC scores. This result suggests that high WMC individuals, when detecting conflict, adjust the level of cognitive control optimally so that their performance is less susceptible to the presence of a distractor. In Experiment 2, we quantified the CAR in a sustained manner as the ratio of the conflict effect from predominantly incongruent blocks to the conflict effect from predominantly congruent blocks. Again, the CAR varied from negative to zero as WMC increased. These results suggest that WMC may reflect, in addition to the ability to maintain a level of control, the ability to adjust the level of control appropriately to the contextual demands.     

Can the LTSI Predict Transfer Performance? Testing intent to transfer as a proximal transfer of training outcome

Law enforcement personnel (n = 235) were administered the Learning Transfer Systems Inventory (LTSI) and a transfer measure after completing leadership development training. Although most studies using the LTSI have focused on validation efforts in different linguistic settings, this study is one of the few to examine the relationship between the LTSI factors and a proximal transfer outcome score (as measured by intent to transfer). Motivation to transfer, transfer design, and transfer performance expectations had the strongest relationship with intent to transfer, and the motivation subscales (motivation to transfer, performance expectations, and outcome expectations) accounted for the largest amount of unique variance in intent to transfer.     

Scoring Biodata: Is it rational to be quasi‐rational?

Five quasi‐rational biodata scales were developed by empirically keying biodata items to predict scores on a measure of the Big Five dimensions of personality. The criterion‐related validities of the quasi‐rational scales were compared to empirical and rational biodata keying methods using supervisory ratings of job performance as the criterion. Empirical keying outperformed the quasi‐rational and rational methods (which had similar validities).     

Valence and the development of immediate and long-term false memory illusions

Across five experiments we examined the role of valence in children's and adults’ true and false memories. Using the Deese/Roediger-McDermott paradigm and either neutral or negative-emotional lists, both adults’ (Experiment 1) and children's (Experiment 2) true recall and recognition was better for neutral than negative items, and although false recall was also higher for neutral items, false recognition was higher for negative items. The last three experiments examined adults’ (Experiment 3) and children's (Experiments 4 and 5) 1-week long-term recognition of neutral and negative-emotional information. The results replicated the immediate recall and recognition findings from the first two experiments. More important, these experiments showed that although true recognition decreased over the 1-week interval, false recognition of neutral items remained unchanged whereas false recognition of negative-emotional items increased. These findings are discussed in terms of theories of emotion and memory as well as their forensic implications.
