Synthesis and Characterization of Silver‐Nanoparticle‐Deposited α‐Bi2Mo3O12 Nanorods
Authors: Ghule Anil Vithal , Ghule Kalyani , Tzing Shin‐Hwa , Ling Yong‐Chien 
Published: May 2007

AbstractSilver (Ag) nanoparticles with an average size of ca. 10 nm were uniformly deposited on the surface of α‐Bi2Mo3O12 nanorods by using an ultrasound sonication method. Ultrasonic irradiation of preformed α‐Bi2Mo3O12 spherical nanoparticles (ca. 200 nm) in pyridine resulted in α‐Bi2Mo3O12 nanorods (ca. 100 nm diameter). Further, sonication of the mixture of α‐Bi2Mo3O12 nanorods and Ag2O in pyridine yielded a nanocomposite of α‐Bi2Mo3O12 nanorods with deposited Ag nanoparticles and pyridine. Calcination of the nanocomposite at 450 °C afforded pyridine‐free α‐Bi2Mo3O12 nanorods with deposited Ag nanoparticles. A plausible mechanism is proposed. The crystallized Ag nanoparticles are uniformly deposited on the surface, with bismuth (Bi) as the preferential binding site, as revealed by time‐of‐flight secondary ion mass spectrometry (TOF‐SIMS). Structural, compositional and morphological characterization of the products is carried out by using transmission electron microscopy, energy‐dispersive X‐ray analysis, scanning electron microscopy, thermogravimetric analysis, X‐ray diffraction, X‐ray photoelectron spectroscopy and TOF‐SIMS.

Social value related response latencies: Unobtrusive evidence for individual differences in information processing
Authors: Dehue Francine M. J. , McClintock Charles G. , Liebrand Wim B. G. 
Published: May 2007

AbstractWhile much research concerning decision‐making in interdependency situations concentrates on the influence of social values or different preferences for certain distributions of outcomes for self and other (McClintock, 1978), little attention has been paid to the cognitive processes underlying the expression of these different social values. The present research focuses on the cognitive processes by examining the influence of the dominant social values on decision‐makers' response latencies (RLs) in interdependency situations. Using the Ring Measure of Social Values (Liebrand 1984), three experiments were conducted to assess these RLs. Experiment 1 examines the reliability of the social value construct and the RL effect. Experiments 2 and 3 investigate the generality of the RL effect across presentation of combinations of own and other's outcomes (all positive versus all negative). As predicted, RLs were shorter for individualists than for cooperators and competitors. Further, regardless of values, shorter RLs occurred across experiments when own outcomes are positive rather than negative. More important, the predicted interaction between social value and outcome distribution was observed, reflecting increasing RLs for cooperators as their joint outcomes decreased, longer RLs for individualists when own outcomes were negative rather than positive, and longer RLs for competitors when they were outcome disadvantaged rather than advantaged relative to other. These findings are consistent with the expectation that (I) the transformations associated with different social values require different cognitive processes, and (2) subsequent to the value transformations of outcomes, RLs increase when the utility of the transformed outcome distributions decreases.
Reactive effects of concurrent verbalization in person perception tasks
Authors: Mumma Gregory H. , Draguns Juris G. , Seibel Robert 
Published: May 2007

AbstractThe reactive effects of concurrent verbalization (CV) on task performance in impression formation research have not been investigated, despite increasing use of this process tracing method. Since many person perception tasks involve multiple trials, assessment of reactivity should focus on carry‐over and reactive‐practice effects, as well as changes in task performance concurrent with thinking aloud. An experimental method for assessing these three forms of reactivity was demonstrated in an information‐request impression formation task. Concurrent reactive effects were found for both continuous and intermittent CV. For the former, task processing was mildly slowed but altered in a manner suggestive of more efficient learning of, and memory for cues requested early in task performance. The substantial slowing of task processing during trial 1 intermittent CV largely disappeared by trial 2, indicating that subjects may require more practice for this method to be used effectively. The results for continuous CV are in line with recent findings which are inconsistent with certain predictions from the predominant theory of verbal protocol generation (Ericsson and Simon, 1984). Investigators using CV are urged to incorporate empirical checks for reactivity into their experimental designs.
Politics and participation: Some antecedents of young people's attitudes to the political system and political activity
Authors: Bynner John , Ashford Sheena 
Published: May 2007

AbstractThe antecedents of political disaffection and political activism have been extensively studied in adult populations, producing two models of political protest, the ‘dissatisfaction model’, suggesting that protest action is rooted in political disaffection, and the ‘resource model’ which bases interest in politics in a sense of political self‐efficacy. There has been a dearth of research extending this theorizing to young people of prevoting age. The present study presents the results of regression analysis applied to longitudinal data collected in a U.K. Programme of research and economic and political socialization, the ESRC 16‐19 Initiative. The analysis relates ‘lack of interest in politics’, ‘intention not to vote’ and ‘political activity’, to attitudes, personality characteristics, experience and circumstances measured earlier. It is concluded that political disaffection including lack of interest and intention not to vote, is strongly associated with a growing cynicism about politics rooted in poor educational performance and a working class family background. The connections with activism are negative but much weaker, suggesting the potential for protest activity across a wider spectrum of youth. This lends support to Marsh's (1990) view that given the right circumstances, protest action under both the ‘resource model’, and the ‘dissatisfaction model’, can apply.
Cognitive models of stereotype change (4): Motivational and cognitive influences
Authors: Johnston Lucy , Hewstone Miles , Pendry Louise , Frankish Clive 
Published: May 2007

AbstractThree experiments investigating the effects of cognitive and motivational factors on stereotype change are reported. Trait ratings in all three experiments showed there to be greater stereotype‐change when stereotype‐inconsistent information was dispersed across many group members than when it was concentrated in only a few. A sorting task (Experiment 1) indicated that, in the concentrated conditions the stereotype disconfirmers were more strongly isolated from the rest of the group than in the dispersed conditions. Free recall protocols (Experiment 2) showed greater memory for the target exemplars when subjects anticipated interaction with a group member than when no interaction was anticipated. The questions subject chose to ask target group exemplars were also influenced by anticlpated future interaction. Subjects chose more stereotype‐inconsistent questions when interactian was anticipated than when no interaction was anticipated. Experment 3 showed the impact of stereotype‐inconsistent information to be greater when expectancies for the stereotyped group are weaker A cued‐recall task yielded evidence of spontaneous subtyping.All these studies support the subtyping model, even in the presence of cognitive and motivational factors that might be expected to impede stereotype change.
Group size, controllability of group membership, and comparative dimension as determinants of intergroup discrimination
Authors: Lindeman Marjaana , Koskela Päivi 
Published: May 2007

AbstractWe expected that, when group members cannot control their group membership, majority members show ingroup favouritism on task‐relevant dimension, whereas minority members were expected to show ingroup favouritism on task‐irrelevant dimension (hypothesis I) In addition, it was expected that intergroup comparisons will change when group membership changes from uncontrollable to controllable. Based on Social Identity Theory, two alternative hypotheses were explored: Compared with uncontrollable settings, ingroup bias will decrease (2a) or increase (2b) in controllable settings. Ninety‐two subjects were divided into four groups (minority versus majority, controllable versus uncontrollable group membership), allegedly on the basis of their essay writing style. The results supported the first hypothesis. Hypothesis 2a received support among the majority members and hypothesis 2b among the minority members. The findings are discussed in terms of Social Identity Theory and the effect the perceived control of group membership and the dimension may have on intergroup comparisons.
Contrary effects of group cohesiveness in minority influence: Intergroup categorization of the source and levels of influence
Authors: Kozakaï Toshiaki , Moscovici Serge , Personnaz Bernard 
Published: May 2007

AbstractThe roles of group cohesiveness and intergroup categorization of the source in minority influence were studied in a 2 (high versus low cohesiveness) × 2 (ingroup versus outgroup source) × 3 (phases) factorial design. Six subjects forming a group were confronted with a confederate defending a minority position in a perceptual task. The results indicated a manifest influence effect (slide colour), accompanied by a latent polarization (afterimage) in the high cohesrveness/outgroup source condition, and a latent unfluence effect in the low cohesiveness/ingroup source condition.
