Two studies investigated interactions between health providers and patients, using Semin and Fiedler's linguistic category model. In Study 1 the linguistic category model was used to examine perceptions of the levels of linguistic intergroup bias in descriptions of conversations with health professionals in hospitals. Results indicated a favourable linguistic bias toward health professionals in satisfactory conversations but low levels of linguistic intergroup bias in unsatisfactory conversations. In Study 2, the language of patients and health professionals in videotaped interactions was examined for levels of linguistic intergroup bias. Interpersonally salient interactions showed less linguistic intergroup bias than did intergroup ones. Results also indicate that health professionals have high levels of control in all types of medical encounters with patients. Nevertheless, the extent to which patients are able to interact with health professionals as individuals, rather than only as professionals is a key determinant of satisfaction with the interaction.

As marketers and researchers we understand quality from the consumer's perspective, and throughout contemporary service quality literature there is an emphasis on what the consumer is looking for, or at least that is the intention. Through examining the underlying assumptions of dominant service quality theories, an implicit dualistic ontology is highlighted (where subject and object are considered independent) and argued to effectively negate the said necessary consumer orientation. This fundamental assumption is discussed, as are the implications, following a critical review of dominant service quality models. Consequently, we propose an alternative approach to service quality research that aims towards a more genuine understanding of the consumer's perspective on quality experienced within a service context. Essentially, contemporary service quality research is suggested to be limited in its inherent third-person perspective and the interpretive, specifically phenomenographic, approach put forward here is suggested as a means of achieving a first-person perspective on service quality.

Two experiments were conducted to test predictions derived from social identity/self-categorization theory concerning the role of group norms in attitude-behavior consistency. In Experiment 1, 160 students who could be classified as having a more or less certain target attitude were exposed to attitude congruent versus incongruent normative support from a relevant reference group (own university) under conditions of low versus high group salience. Experiment 2 was very similar in design and methodology (N=180), but a different correlate of attitude accessibility was used (an experimental manipulation of repeated expression), the target attitude was changed, and the reference group was gender. Across the 2 experiments there was consistent support for the hypothesis that participants would behave more in accordance with their attitudes when they received normative support for, rather than opposition to, their original attitude from a relevant reference group (i.e., their ingroup, not an outgroup). There was slightly weaker support for the second hypothesis that this effect would be stronger under high-than low-salience conditions. The third hypothesis (see Fazio, 1986), that attitude certainty and repeated expression of the attitude would strengthen attitude-behavior consistency, was well supported, as was the expectation that accessibility effects would be independent of reference group norm effects on attitude-behavior consistency.

In this paper we construct predictor-corrector (PC) methods based on the trivial predictor and stochastic implicit Runge-Kutta (RK) correctors for solving stochastic differential equations. Using the colored rooted tree theory and stochastic B-series, the order condition theorem is derived for constructing stochastic RK methods based on PC implementations. We also present detailed order conditions of the PC methods using stochastic implicit RK correctors with strong global order 1.0 and 1.5. A two-stage implicit RK method with strong global order 1.0 and a four-stage implicit RK method with strong global order 1.5 used as the correctors are constructed in this paper. The mean-square stability properties and numerical results of the PC methods based on these two implicit RK correctors are reported.

A central problem in visual perception concerns how humans perceive stable and uniform object colors despite variable lighting conditions (i.e. color constancy). One solution is to 'discount' variations in lighting across object surfaces by encoding color contrasts, and utilize this information to 'fill in' properties of the entire object surface. Implicit in this solution is the caveat that the color contrasts defining object boundaries must be distinguished from the spurious color fringes that occur naturally along luminance-defined edges in the retinal image (i.e. optical chromatic aberration). In the present paper, we propose that the neural machinery underlying color constancy is complemented by an 'error-correction' procedure which compensates for chromatic aberration, and suggest that error-correction may be linked functionally to the experimentally induced illusory colored aftereffects known as McCollough effects (MEs). To test these proposals, we develop a neural network model which incorporates many of the receptive-field (RF) profiles of neurons in primate color vision. The model is composed of two parallel processing streams which encode complementary sets of stimulus features: one stream encodes color contrasts to facilitate filling-in and color constancy; the other stream selectively encodes (spurious) color fringes at luminance boundaries, and learns to inhibit the filling-in of these colors within the first stream. Computer simulations of the model illustrate how complementary color-spatial interactions between error-correction and filling-in operations (a) facilitate color constancy, (b) reveal functional links between color constancy and the ME, and (c) reconcile previously reported anomalies in the local (edge) and global (spreading) properties of the ME. We discuss the broader implications of these findings by considering the complementary functional roles performed by RFs mediating color-spatial interactions in the primate visual system.

The notion of implicature was first introduced by Paul Grice (1967, 1989), who defined it essentially as what is communicated less what is said. This definition contributed in part to the proliferation of a large number of different species of implicature by neo-Griceans. Relevance theorists have responded to this by proposing a shift back to the distinction between "explicit" & "implicit" meaning (corresponding to "explicature" & "implicature," respectively). However, they appear to have pared down the concept of implicature too much, ignoring phenomena that may be better treated as implicatures in their overgeneralization of the concept of explicature. These problems have their roots in the fact that explicit & implicit meaning intuitively overlap & thus do not provide a suitable basis for distinguishing implicature from other types of pragmatic phenomena. An alternative conceptualization of implicature based on the concept of "implying" with which Grice originally associated his notion of implicature is thus proposed. From this definition, it emerges that implicature constitutes something else inferred by the addressee that is not literally said by the speaker. Instead, it is meant in addition to what the speaker literally says & is consequently defeasible like all other types of pragmatic phenomena. 1 Figure, 60 References.

This paper reports an investigation into the antecedents of commitment in non-Western industrial marketing relationships. The authors draw the antecedents from extant literature and posit that commitment is related to trust (integrity and reliability), communication quality, conflict, and similarity (social, ethnic, and economic). It is further argued that trust mediates the effects of communication, conflict, and similarity on commitment. As an extension, the authors examine the moderating effects of normative contracts (an implicit understanding of roles and responsibilities) on the construct interrelationships. The hypotheses are tested using data collected from approximately 150 industrial marketing relationships sampled from overseas Chinese firms. The results generally support the authors' framework; however, the mediating hypotheses are not supported. There is evidence of systematic differences in the effects of the studied antecedents on commitment and trust. Furthermore, a multigroup analysis provides evidence of significant moderating effects due to contracting mode. The study provides new insights into the theory and practice of industrial marketing.

Using a social identity perspective, two experiments examined the effects of power and the legitimacy of power differentials on intergroup bias. In Experiment 1, 125 math-science students were led to believe that they had high or low representation in a university decision-making body relative to social-science students and that this power position was either legitimate or illegitimate. Power did not have an independent effect on bias; rather, members of both high and low power groups showed more bias when the power hierarchy was illegitimate than when it was legitimate. This effect was replicated in Experiment 2 (N =105). In addition, Experiment 2 showed that groups located within an unfair power hierarchy expected the superordinate power body to be more discriminatory than did those who had legitimately high or low power. The results are discussed in terms of their implications for group relations.

Subcycling, or the use of different timesteps at different nodes, can be an effective way of improving the computational efficiency of explicit transient dynamic structural solutions. The method that has been most widely adopted uses a nodal partition. extending the central difference method, in which small timestep updates are performed interpolating on the displacement at neighbouring large timestep nodes. This approach leads to narrow bands of unstable timesteps or statistical stability. It also can be in error due to lack of momentum conservation on the timestep interface. The author has previously proposed energy conserving algorithms that avoid the first problem of statistical stability. However, these sacrifice accuracy to achieve stability. An approach to conserve momentum on an element interface by adding partial velocities is considered here. Applied to extend the central difference method. this approach is simple. and has accuracy advantages. The method can be programmed by summing impulses of internal forces, evaluated using local element timesteps, in order to predict a velocity change at a node. However, it is still only statistically stable, so an adaptive timestep size is needed to monitor accuracy and to be adjusted if necessary. By replacing the central difference method with the explicit generalized alpha method. it is possible to gain stability by dissipating the high frequency response that leads to stability problems. However. coding the algorithm is less elegant, as the response depends on previous partial accelerations. Extension to implicit integration, is shown to be impractical due to the neglect of remote effects of internal forces acting across a timestep interface. (C) 2002 Elsevier Science B.V.

The influence of complex plaque morphology on the extent of demand-induced ischemia in unselected patients is not well defined. We sought to investigate the functional significance of lesion morphology in patients who underwent coronary angiography and dobutamine stress echocardiography (DSE).,Angiography and DSE were performed within a 6-month period (mean 1 +/- 1 month) in 196 patients. Angiographic assessments involved quantification of stenosis severity, assessment of the extent of jeopardized myocardium, and categorization of plaque morphology according to the Ambrose classification. DSE was interpreted by separate investigators with respect to wall motion score index (WMSI) and number of coronary territories involved. A general linear model was constructed to assess,the independent contribution of patient characteristics and angiographic and DSE results with respect to extent of ischemic myocardium. Complex lesion morphology was seen in 62 patients (32%). Patients with complex lesions were more likely to have had prior myocardial infarction (p < 0.001) and be current smokers (p = 0.03). During angiography, they exhibited a trend toward a greater number of diseased vessels, had a greater coronary jeopardy score (p < 0.001) and more frequent collateral flow (p = 0.03). During echocardiography, patients had a higher stress WMSI (p < 0.001) and were more likely to show ischemia in all 3 arterial territories (p < 0.01). On multivariate regression, the coronary artery jeopardy score and the presence of complex plaque morphology were independent predictors of the extent of ischemic myocardium (R 2 = 34%, p < 0.001). Thus, patients with complex plaque morphology are older, more likely to smoke, and more likely to have had prior myocardial. infarction. They exhibit more extensive disease with higher coronary jeopardy scores and a higher resting and peak stress WMSI. Despite these differences, complex plaque morphology remains an independent predictor of the extent of ischemia during stress. (C) 2003 by Excerpta Medica, Inc.

O artigo estuda um aspecto da reforma do Estado que, segundo o autor, tem sido sistematicamente negligenciado pelas atuais propostas que focalizam o modelo da administra????o gerencial. Trata-se das fun????es vitais do governo de tomar decis??es cr??ticas e adotar pol??ticas diante das mudan??as provocadas pela revolu????o global. Segundo Dror, as tarefas de alto comando (high-order tasks) de definir trajet??rias e as novas formas de governan??a exigem um ajuste significativo do governo central. Este ajuste refere-se, principalmente, ?? concep????o e ao desenvolvimento de um novo padr??o de funcion??rios do primeiro escal??o p??blico, o qual contribuiria com conhecimento e perspectivas para enfrentar as tarefas de alto comando. O autor estabelece uma tipologia para caraterizar a evolu????o do perfil do servi??o p??blico, marcando suas fases hist??ricas: a) tipo alpha (status atribu??do, fus??o de pap??is pol??ticos e administrativos); b) tipo beta (compra de cargos governamentais) e c) tipo gamma (quase profissionalismo). O novo funcion??rio s??nior, do tipo delta, se concentraria nas quest??es de ordem estrat??gica, deixando as fun????es gerenciais para servidores do tipo gamma e para os servi??os t??cnicos. Ap??s uma breve an??lise, Dror conclui que o funcionalismo p??blico de primeiro escal??o, na maioria dos pa??ses (com exce????o de alguns pa??ses do Sudeste Asi??tico), encontra-se obsoleto, com base profissional inadequada e capacidade insuficiente para lidar com escolhas cr??ticas.

Este artigo visa compreender at?? que ponto as pr??ticas gerenciais incorporam as dimens??es da satisfa????o e motiva????o no trabalho de servidores p??blicos na atualidade. Aborda os modelos de administra????o burocr??tica e gerencial, exp??e as disfun????es do modelo ideal da burocracia weberiana, apresenta a motiva????o para o trabalho e suas implica????es, e evidencia a carreira de Especialista em Pol??ticas P??blicas e Gest??o Governamental (EPPGG) no intuito de apresentar uma alternativa poss??vel de proporcionar satisfa????o e motiva????o no trabalho, por meio do enriquecimento do cargo. A metodologia consta de uma pesquisa qualitativa, na qual se fez uso de entrevistas semiestruturadas aplicadas junto a tr??s EPPGG. Utilizou-se da an??lise de conte??do com uso da t??cnica de categoriza????o para a an??lise os dados. Os resultados demonstraram a satisfa????o e motiva????o dos gestores, a preval??ncia da administra????o burocr??tica com fortes ind??cios da administra????o gerencial e aus??ncia de disfun????es burocr??ticas. Evidenciaram que o modelo da nova gest??o p??blica, uma vez implantado conforme descrito na teoria, pode combater disfun????es burocr??ticas e contribuir para a satisfa????o e motiva????o dos servidores p??blicos. Destaca-se a relev??ncia de estudos posteriores, visto que foram apontadas diversidades de condi????es de trabalho de ??rg??o para ??rg??o e dificuldades enfrentadas no in??cio da carreira.

O objetivo da presente pesquisa é compreender quais são as ações da Secretaria Municipal de Educação de Vitória (Seme) para que a Educação Física, enquanto componente curricular, atue no sentido de promover e garantir a cidadania. A relevância da pesquisa está na importância em se discutir a cidadania na formação escolar e em levantar dados que apontem as ações da gestão educacional do Município no sentido de garantir que a Educação Física cumpra um de seus objetivos, a saber, a formação de cidadãos. Trata-se de uma pesquisa qualitativa, de abordagem exploratória/descritiva. Para coleta de dados, utilizou-se documentos da Seme, bem como a realização de uma entrevista coletiva na qual estavam presentes professores de Educação Física que atuam administrativamente na Secretaria. O desenvolvimento do estudo se procedeu em três etapas: no primeiro momento, foi realizado um levantamento bibliográfico; na segunda etapa, efetivou-se a análise documental nas Diretrizes Curriculares da Prefeitura Municipal de Vitória (PMV) e na Lei 4747/98 que institui o Sistema de Ensino do Município; na última etapa, realizamos uma entrevista coletiva com gestores da Seme com formação em Educação Física. A técnica utilizada para a tabulação dos dados foi a análise de conteúdo, que nos permitiu efetivar um recorte dos textos de acordo com os conteúdos mais significativos, para o posterior agrupamento e categorização das unidades de respostas. Mediante o percurso metodológico descrito acima, foi possível compreender a organização/funcionamento da Coordenação de Desportos da Secretaria, assim como suas ações voltadas para que a Educação Física se reconheça enquanto promotora de cidadania e colabore com a formação cidadã. Constatou-se que expressões como “cidadania”, “direito”, “participação” e “emancipação” aparecem mais no discurso dos gestores, e menos nos documentos e nas ações. Desse modo, pontuamos que se torna evidente que poucas são as estratégias sistematizadas por meio da Seme para que a Educação Física, enquanto componente curricular, possa cooperar com a formação cidadã.

As China turns increasingly to the cultivation of soft power in the course of developing its foreign policy, the use of political rhetoric and its explicit and implicit audiences become more and more important, both on a bilateral level and within the international arena at large. Using the case of China's relations with African countries, this article examines key themes within China's diplomatic narrative regarding its role on the African continent and contrasts with Western and African responses.

Emotions play a central role in our daily lives, influencing the way we think and act, our health and sense of well-being, and films are by excellence the form of art that exploits our affective, perceptual and intellectual activity, holding the potential for a significant impact. Video is becoming a dominant and pervasive medium, and online video a growing entertainment activity on the web and iTV, mainly due to technological developments and the trends for media convergence. In addition, the improvement of new techniques for gathering emotional information about videos, both through content analysis or user implicit feedback through user physiological signals complemented in manual labeling from users, is revealing new ways for exploring emotional information in videos, films or TV series, and brings out new perspectives to enrich and personalize video access. In this work, we reflect on the power that emotions have in our lives, on the emotional impact of movies, and on how to address this emotional dimension in the way we classify and access movies, by exploring and evaluating the design of iFelt in its different ways to classify, access, browse and visualize movies based on their emotional impac
