Emotion regulation meets emotional attention: the influence of emotion suppression on emotional attention depends on the nature of the distracters

Recent evidence has suggested a crucial role of people’s current goals in attention to emotional information. This asks for research investigating how and what kinds of goals shape emotional attention. The present study investigated how the goal to suppress a negative emotional state influences attention to emotion-congruent events. After inducing disgust, we instructed participants to suppress all feelings of disgust during a subsequent dot probe task. Attention to disgusting images was modulated by the sort of distracter that was presented in parallel with disgusting imagery. When disgusting images were presented together with neutral images, emotion suppression was accompanied by a tendency to attend to disgusting images. However, when disgusting images were shown with positive images that allow coping with disgust (i.e., images representing cleanliness), attention tended away from disgusting images and toward images representing cleanliness. These findings show that emotion suppression influences the allocation of attention but that the successful avoidance of emotion-congruent events depends on the availability of effective distracters.

Valor percebido e o comportamento do consumidor de supermercado: um estudo exploratório em uma média cidade brasileira

Este estudo esteve envolvido com o desenvolvimento de um modelo para avaliação de valor de supermercado, sob a perspectiva do consumidor. O conceito de valor empregado neste trabalho parte da idéiade que um comportamento somente deve ser levado adiante caso o prazer decorrente seja superior à dor relacionada à obtenção desse prazer. Em Marketing, isto quer dizer que o consumo de determinado bem ou serviço exige do indivíduo uma certa quantidade de sacrifício (sacrifício percebido) para gozar dos benefícios associados (qualidade percebida). Em outras palavras, o consumidor precisa levar em consideração uma série de fatores numa situação de n avaliação e escolha. Para tanto, foram feitas duas consultas a clientes de supermercado do sexo feminino, pertencentes às classes A e B, na cidade de Campo Grande (MS), sendo uma qualitativa (n = 25) e outra quantitativa (n = 200). Os resultados indicam que valor percebido (VP) é uma função linear de qualidade percebida (QP), mas não de sacrifício percebido (SP). Portanto, duas das quatro hipóteses do estudo não foram confirmadas. Cerca de três quartos das mulheres preferem fazer ·uma compra pesada por mês e várias avulsas", aliás comportamento mais evidente nas faixa etárias mais elevadas. Para metade das entrevistadas, fazer compra em supermercado dá mais prazer do que trabalho. A maioria das mulheres que não trabalha fora sente prazer em fazer compra, ao contrário das mulheres que trabalham fora que acham isso uma obrigação. Por último, as mulheres que não trabalham fora, as de idade mais elevada e aquelas que consideram a compra um prazer, valorizam melhor o seu supermercado. O estudotambém permitiu verificar as características determinantes do supermercado que o cliente leva em consideração. Os atributos mais valorizados pelas entrevistadas foram substituiçao de produtos estragados e/ou vencidos e limpeza da loja. No entanto, elas usaram exposiçêo e organizaçao dos produtos, limpeza da loja e qualidade dos produtos hortifrutícolas para perceber valor. Os resultados dos testes de hipóteses parecem indicar que não é necessário o uso de variáveis de baixo nível de percepção (atributos de qualidade e de custo) para medir VP de supermercado. Os três atributos que permaneceram no modelo para explicar VP, através de QP (limpeza da loja, exposiçêo e organizaçao dos produtos e qualidade dos produtos hortifrutlcolas), o fazem moderadamente (R2 = 24,7%). Por outro lado, na avaliação global que as entrevistadas fizeram das lojas, QP (agora como variável independente) apresenta um coeficiente de explicação R 2 = 37,4%, resultadosuperior aoverificado quando a relação se deu com atributos específicos. Entretanto, se os clientes percebem valor apenas se valendo de QP (avaliação global), a formação da percepção de qualidade é feita usando sinais específicos associados ao produto "supermercado", sinais estes que incluem os três atributos que permaneceram no modelo. Assim, um modelo que inclui variáveis de percepção mais elevada (QP e SP) para inferir VP permite responder à seguinte questão: qual é a avaliação global que os clientes fazem de seu supermercado? Por outro lado, um modelo que julga VP a partir de atributos especificos (variáveis de baixo nível de percepção) deve responder à seguinte indagação: como se dá a percepção de valor do cliente em relação ao seu supermercado? Outros resultados são discutidos e também são apresentadas sugestões para futuras pesquisas e as principais implicações acadêmicas e empresariais .

Tais problemas foram: o saneamento total das necessidades operacionais do condomínio no que diz respeito à manutenção predial, a organização detalhada da documentação contábil, a criação de procedimentos de controle administrativos e financeiros, e, finalmente, o desenvolvimento de nova mentalidade quanto à forma de relacionamento entre o administrador predial e os condôminos.

Fatores de influência na produção de leite bovino sobre os níveis da contagem bacteriana total

The objective of this study was to evaluate the influence of milking procedures on the levels of total bacterial count (TBC) in bovine milk. In the first study the influences of procedures for hygienic milking, cleaning of milking equipment and milk cooling tanks on the TBC levels were evaluated. Four bulk samples of milk were collected from each tank in eight properties for TBC analysis, employing the flow cytometry method. A questionnaire was applied in each property to assess the current situation of milking procedures on each production system that took part on this research, followed by training of employees in good agricultural practices in the production of milk and monitoring of the TBC measurements. The methodology for analysis of longitudinal data was considered, focusing on random effects models. The results showed that the handling procedures for milking and the cleanliness of the cooling tank contributed to a further reduction in the levels of TBC raw milk cooling tanks. The second study aimed to describe the percentage of the properties that comply with the Normative Instruction Nº 51 (Brazil s IN 51) with regard to total bacterial count (TBC) in bovine milk. The study was conducted from January 2010 to July 2011. Milk samples were collected from the eight properties selected for TBC analysis by the flow cytometry method. Again, on each property a questionnaire was applied to assess the current situation of milking procedures on each production system that took part on this research, followed by training of employees in good agricultural practices in the production of milk and monitoring of the TBC measurements. The methodology of marginal models based on Generalized Estimate Equations (GEEs) was followed in the statistical analysis. The results showed that the handling procedures of the milking and the cleanliness of the cooling tanks contributed to a considerable percentage of the properties that reached the limits of TBC established by IN 51

Residues of calcium hydroxide-based intracanal medication associated with different vehicles: A scanning electron microscopy evaluation

This study evaluated the presence of residues after removal of calcium hydroxide [Ca(OH)2] associated with different vehicles. Thirty single-rooted teeth were instrumented to a master apical file #25 using 2.5% NaOCl as main irrigant and 17% trisodium EDTA (ethylenediaminetetraacetic acid) as final agent irrigant. Then, the root canals were dressed with Ca(OH)2 associated with silicone oil (Group 1), 2% chlorhexidine gluconate (Group 2), or propylene glycol (Group 3). After coronal sealing, all teeth were kept in a moist environment at room temperature. After 7 days, the teeth were reopened and medicaments were removed using 5 mL of saline solution and instrumentation with master apical file followed by new irrigation with 5 mL of 2.5% NaOCl. Subsequently, teeth were split longitudinally and assessed by scanning electron microscopy. The wall cleanliness of the cervical and apical thirds of the roots were evaluated and scored by three blinded examiners. Statistical analysis was performed using KruskalWallis and Wilcoxon tests at 5% level of significance. All roots had residues of Ca(OH)2 on the canal walls. All experimental groups had similar results (P > 0.05) regardless of the third evaluated. There was significant difference between the apical and cervical thirds only in Group 3 (P < 0.05). Association of different vehicles to Ca(OH)2 does not influence the persistence of residues on the root canal walls. Microsc. Res. Tech. 2012. (C) 2012 Wiley Periodicals, Inc.

AC impedance study of Ni, Fe, Cu, Mn doped ceria stabilized zirconia ceramics

Doped zirconia has been used in electronic applications in the cubic crystalline phase. Ceria-stabilized tetragonal zirconia presents high toughness and can also be applied as solid electrolytes. The tetragonal phase of zirconia can be stabilized at room temperature with ceria in a broad range of composition. However, CeO2-ZrO2 has low sinterability. so it is important to investigate the effect of sintering dopants. In this study the effect of iron, copper. manganese and nickel was investigated. The dopants such as iron and copper lowered the sintering temperature from 1600 degreesC down to 1450 degreesC, with a percentage of tetragonal phase retained at room temperature higher than 98% and also with an increase of the electrical conductivity. The electrical conductivity was measured using impedance spectroscopy. The grain boundary contribution was determined and the activation energy associated with the ionic conduction was 1.04 eV. The dopants can also promote a grain boundary cleanliness verified by blocking effect measurement. (C) 2001 Elsevier B.V. Ltd. All rights reserved.

Técnica do grupo focal como método de avaliação do conhecimento de adolescentes sobre saúde bucal

This study aims to the understanding of adolescents regarding oral health, using the Focus Group technique. The study was conducted at three public schools in the city of Araçatuba, São Paulo State, Brazil, with ten students in each. In order to conduct the focus groups, the following words, which featured high error levels, were addressed in survey questions on oral health: oral health; plaque, permanent teeth; fluoride; gum bleeds?; dental floss; transmission of cavities. During the discussions in the focus groups, it was observed that many teenagers were surprised at the situation to which they were submitted and at the topic they were discussing. The word 'oral health' was associated with the condition of cleanliness of the oral cavity, not identifying oral health as part of general health. The term 'transmission of cavities' did not have a sufficient understanding. The term 'permanent tooth' was well understood and was associated with a type of tooth that would not be replaced. The word 'fluoride' had more association with the task of cleaning than protection of the teeth. It is concluded that the use of the focus group technique is of great importance in the interpretation of the knowledge of adolescents on oral health and the appropriateness of the terminology of questionnaires on the same subject.

Vibration and oil analysis for monitoring problems related to water contamination in rolling

Trying to reduce particle contamination in lubrication systems, industries of the whole world spend millions of dollars each year on the improvement of filtration technology. In this context, by controlling fluid cleanliness, some companies are able to reduce failures rates up to 85 percent. However, in some industries and environments, water is a contaminant more frequently encountered than solid particles, and it is often seen as the primary cause of component failure. Only one percent of water in oil is enough to reduce life expectancy of a journal bearing by 80 percent. For rolling bearing elements, the situation is worse because water destroys the oil film and, under the extreme temperatures and pressures generated in the load zone of a rolling bearing element, free and emulsified water can result in instantaneous flash-vaporization giving origin to erosive wear. This work studies the effect of water as lubricant contaminant in ball bearings, which simulates a situation that could actually occur in real systems. In a designed bench test, three basic lubricants of different viscosities were contaminated with different contents of water. The results regarding oil and vibration analysis are presented for different bearing speeds.
