Octapod-shaped,nanosized, amorphous precipitates in a crystalline ferrite matrix

The development of uniquely octapod-shaped nanosized amorphous silicon–nitride precipitates in a ferrite matrix was observed upon nitriding of Fe–4.5at.%Si alloy. The legs of the amorphous precipitate are oriented along ?1?1?1?-directions of the ferrite. The occurrence of such peculiarly shaped amorphous silicon–nitride precipitates, which experience a volume misfit of more than 100% with the surrounding ferrite, was attributed to precipitate growth influenced by long-range diffusion within the evolving highly anisotropic stress field around the developing precipitates after nucleation.     

Motivational support provided via email improves the effectiveness of internet-delivered self-help treatment for insomnia: A randomized trial

Internet-delivered treatment is effective for insomnia, but little is known about the beneficial effects of support. The aim of the current study was to investigate the additional effects of low-intensity support to an internet-delivered treatment for insomnia. Two hundred and sixty-two participants were randomized to an internet-delivered intervention for insomnia with (n = 129) or without support (n = 133). All participants received an internet-delivered cognitive behavioral treatment for insomnia. In addition, the participants in the support condition received weekly emails. Assessments were at baseline, post-treatment, and 6-month follow-up. Both groups effectively ameliorated insomnia complaints. Adding support led to significantly higher effects on most sleep measures (d = 0.3–0.5; p < 0.05), self-reported insomnia severity (d = 0.4; p < 0.001), anxiety, and depressive symptoms (d = 0.4; p < 0.01). At the 6-month follow-up, these effects remained significant for sleep efficiency, sleep onset latency, insomnia symptoms, and depressive symptoms (d = 0.3–0.5; p < 0.05). Providing support significantly enhances the benefits of internet-delivered treatment for insomnia on several variables. It appears that motivational feedback increases the effect of the intervention and encourages more participants to complete the intervention, which in turn improves its effectiveness.     

Sexual identity and choice of sexual object: From bisexuality to implicate order

Abstract

Stensson J. Sexual Identity and Choice of Sexual Object: From Bisexuality to Implicate Order. Int Forum Psychoanal 1992; 1:93-97. Stockholm. ISSN 0803-706 X

Freud's concept of bisexuality leads to contradictory consequences. Seeing choice of sexual object in the light of unconscious primal phantasies as coding systems, unfolds new possibilities. Taking the primal scene phantasy as a preconceptual code for mature sexuality, I make a limited and preliminary attempt to outline some possible outcomes of interactions between primal scene and oral phantasies, taking help from the theoretical physicist David Bohm's ideas on implicate order.     

The risky side of inspirational appeals in personal selling: when do customers infer ulterior salesperson motives?

In personal selling, the inspirational appeal (IA) is a widely promoted tactic that aims at stimulating customers' values and ideals, thereby evoking emotions and arousing their enthusiasm for a product. However, whether IAs in fact improve or undermine salespeople's success in sales talks remains controversial. Therefore, this study examines consequences and key contingencies of IAs in customer–salesperson interactions in a retailing context, using multisource data from several retailing industries for three quantitative studies, comprising a total sample of 590 customer and 174 salesperson responses. Drawing on the Multiple Inferences Model (MIM), the authors show that an IA is likely to drive the customer's inference that the salesperson holds ulterior motives. IAs seem to be particularly detrimental for salespeople with a lack of customer orientation. Beyond expanding research on influence tactics and the ambivalent role of IAs in retailing interactions, these findings can guide practitioners about when to refrain from using an IA.     

Applying multiple models to predict clinicians’ behavioural intention and objective behaviour when managing children's teeth

This study used multiple theoretical approaches simultaneously to predict an objectively measured clinical behaviour. The six theoretical approaches were: The Theory of Planned Behaviour (TPB), Social Cognitive Theory (SCT), Common Sense Self-Regulation Model (CS-SRM), Operant Learning Theory (OLT), Action Planning (AP) and the Precaution Adoption Process (PAP), with knowledge as an additional predictor. Data on variables from these models were collected by postal survey. Data on the outcome behaviour, the evidence-based practice of placing fissure sealants, was collected from clinical records. Participants were 133 dentists (64% male) in Scotland. Variables found to predict the behaviour were: intention, attitude, perceived behavioural control, risk perception, outcome expectancies, self efficacy, habit, anticipated consequences, experienced consequences and action planning. The TPB, SCT, AP, OLT and PAP significantly predicted behaviour but the CS-SRM did not. A combined (Stepwise) regression model included only intention and action planning. Post hoc analyses showed action planning mediated effect of intention on behaviour. Taking a theory-based approach creates a replicable methodology for identifying factors predictive of clinical behaviour and for the design and choice of interventions to modify practice as new evidence emerges, increasing current options for improving health outcomes through influencing the implementation of best practice.
