Relações espaço-temporais como restrições de tomadas de decisões na grande área no futebol

Este estudo investigou as tomadas de decisões de jogadores dentro da grande área do futebol com base em variáveis espaciais e espaço-temporais de coordenações interpessoal e extrapessoal. Participaram do estudo 150 jogadores do sexo masculino, com idade entre 18 e 38 anos, e experiência de prática neste esporte de, no mínimo, 7 anos. Foram filmados 12 jogos de futebol de um campeonato amador na Colômbia. As imagens capturadas foram analisadas através do software TACTO, e as variáveis consideradas para análise foram as seguintes: i) ângulo de chute, formado por vetores ligando o jogador com posse de bola a dois componentes do jogo que geravam uma lacuna no gol; ii) ângulo A de passe, composto por vetores conectando o portador da bola ao seu marcador mais próximo e ao seu companheiro de equipe; iii) ângulo B de passe, formado por vetores ligando o portador da bola ao seu companheiro de equipe e ao marcador mais próximo dele; iv) distância interpessoal, caracterizada pela distância entre o jogador com posse de bola e seu defensor mais próximo; v) velocidade e variabilidade relacionadas às mudanças em cada uma dessas medidas. Essas variáveis foram comparadas em relação a situações de chute, passe e drible. Os resultados revelaram que, em relação à decisão de chutar, o ângulo de chute representando a interação entre as possibilidades de completá-lo e de o mesmo ser interceptado, diferiu do mesmo ângulo em que as decisões de passe e drible foram tomadas; e, na decisão de driblar, a distância interpessoal apresentou diferenças com as situações em que o passe foi executado. Concluiu-se que, no caso do chute ao gol e o drible, os ângulos de chute e distâncias interpessoais, respectivamente, funcionaram como variáveis informacionais de coordenações interpessoal e extrapessoal importantes para as tomadas de decisão

Actitudes hacia las matemáticas y rendimiento académico en función de los estudios de acceso y curso en futuros maestros

En este trabajo se analizan las actitudes hacia las Matemáticas de los estudiantes del Grado en Educación Primaria de la Universidad de A Coruña en función del curso y de los estudios de acceso a la Universidad. También se estudia el rendimiento académico según estas dos variables. Se aplica el cuestionario de actitudes PAC de Naya, Soneira, Mato y Torre (2014) con una fiabilidad Alfa de Cronbach de 0.921 a una muestra de 307 estudiantes. El instrumento está formado por 19 ítems con cinco opciones de respuesta tipo Likert y tres dimensiones que miden el autoconcepto, la percepción que tiene el alumno de su profesor y el agrado hacia las Matemáticas. Los resultados muestran que existen diferencias significativas en las actitudes y en el rendimiento en función del itinerario de acceso a la titulación.

Adolescent Trajectories of Depressive Symptoms : co-development of Behavioral and Academic Problems

Purpose: Increasing evidence suggests the existence of heterogeneity in the development of depressive symptoms during adolescence, but little remains known regarding the implications of this heterogeneity for the development of commonly co-occurring problems. In this study, we derived trajectories of depressive symptoms in adolescents and examined the codevelopment of multiple behavioral and academic problems in these trajectories. Methods: Participants were 6,910 students from secondary schools primarily located in disadvantaged areas of Quebec (Canada) who were assessed annually from the age 12 to 16 years. Trajectories were identified using growth mixture modeling. The course of behavioral (delinquency, substance use) and academic adjustment (school liking, academic achievement) in trajectories was examined by deriving latent growth curves for each covariate conditional on trajectory membership. Results: We identified five trajectories of stable-low (68.1%), increasing (12.1%), decreasing (8.7%), transient (8.7%), and stable-high (2.4%) depressive symptoms. Examination of conditional latent growth curves revealed that the course of behavioral and academic problems closely mirrored the course of depressive symptoms in each trajectory. Conclusions: This pattern of results suggests that the course of depressive symptoms and other adjustment problems over time is likely to involve an important contribution of shared underlying developmental process(es).

Event marketing: an innovative promotional tool and its impact on consumer memory and brand awareness

Event Marketing represents a common promotional strategy that involves direct contact between brands and consumers at special events, namely concerts, festivals, sporting events and fairs. Brands have been investing in sponsorship as a means of associating themselves with particular events, essentially with the goal to enhance brand image and brand awareness. Interestingly, the response of consumers to event marketing has not yet been fully understood. This dissertation fills this gap. More specifically, it intends to determine the extent to which sponsoring brands at events favors brand awareness (recall and recognition) and how it relates to brand attitude. Based on three Portuguese music festivals, two studies were conducted to ascertain event sponsorship’s impact on consumer memory, notably Brand Recall and Brand Recognition, and correlation with attitudes towards the brands such as familiarity and liking. The key findings of these studies show that recognition is much higher for those respondents who attended the festivals, presenting a score of 73,9%, in comparison with recall, presenting a much lower score of 37,5%. Further, and surprisingly, it suggests that the ability to recall and recognize sponsoring brands is not associated to consumer attitudes towards the brands. Instead, it relates to the time consumers dedicated to these particular events, that is, the number of music festivals attended.

Por causa do Reino dos Céus Uma leitura de gênero de Mateus 19,1-12 e 5,27-32

Há no Evangelho de Mateus material suficiente para se chegar ao discipulado de iguais porque seu conteúdo reflete uma prática igualitária de Jesus em relação às mulheres. Nesta tese tal prática pode ser verificada através da investigação de duas perícopes nas quais Jesus advoga a causa das mulheres discutindo o direito masculino do divórcio e o adultério: 19,1-12 e 5,27-32. No debate sobre a justa causa para se despedir a mulher, Jesus declara que a volta à criação original não mais concede tal prerrogativa aos homens. Essa discussão ocorre em terreno legal e isso se evidencia pelo termo aitia, cujo significado demonstra que na demanda do divórcio a lei concede ao homem o benefício de encontrar um motivo para acusação. Jesus, por sua vez, declara que pela sua lei todo motivo e acusação contra a mulher se transforma em motivo e acusação contra o próprio homem diante de Deus. O silêncio dos fariseus comprova que os argumentos de Jesus são irrefutáveis, mas o protesto dos seus discípulos revela que não lhes agrada a igualdade social entre os sexos. A resposta final e definitiva de Jesus encontra-se em Mt 19,10 onde pelo uso da metáfora eunuco ele encerra o debate dizendo que somente podem aceitar a sua causa os que abraçarem a causa do Reino dos Céus. Os temas divórcio e adultério permitem estender a discussão para o matrimônio que é a relação social e legal que fundamenta tais práticas, e buscar na Antigüidade as leis e costumes que regiam a vida sexual das mulheres naquele tempo, considerando os ambientes mais relevantes em relação ao mundo bíblico: o mundo greco-romano e o oriente próximo no período entre os séculos IV a.C. e IV d.C. para que, através da pesquisa sobre matrimônio, divórcio, adultério, dote, repúdio e outras sanções relativas à vida sexual das mulheres, se possa chegar aos mecanismos culturais da educação capazes de levar as mulheres à cumplicidade ou à resistência aos seus papéis sociais. Essa pesquisa se encerra com uma apreciação da história da renúncia sexual nos contextos judaico e cristão para projetar o ambiente e o horizonte sócio-religioso que foram palcos da recepção e transmissão de Mt 5,27-32 e Mt 19,1-12, de modo a demonstrar que os argumentos misóginos que se tornaram inerentes à interpretação desses textos são o resultado de uma mentalidade sexista que não corresponde à crítica literária do evangelho.(AU)

The impact of brand owner on consumers' brand perceptions : a development of Heider's Balance Theory

Studies have shown that the brand “owner” is very influential in positioning the brand and when the brand “owner” ceases his or her active role the brand will be perceived differently by the consumers. Balance Theory (HBT), a cognitive psychological theory, studies the triadic relationships between two persons and an entity and predicts that when a person’s original perception of the relationship is disturbed, the person restructures to a new balanced perception. Consequently, this research was undertaken to: conceptualize the brand owner’s impact on consumer’s brand perception; test the applicability of both the static and dynamic predictions of the Heider’s Balance Theory in brand owner-consumer-brand relation (OCB); construct and test a model of brand owner-consumer-brand relation; and examine if personality has an influence on OCB. A discovery-oriented approach was taken to understand the selected market segment, the ready-to-wear and diffusion lines of international designer labels. Chinese Brand Personality Scale, fashion proneness and hedonic and utilitarian shopping scales were developed, and validated. 51 customers were surveyed. Both traditional and extended methods used in the Balance Theory were employed in this study. Responses to liked brand have been used to test and develop the model, while those for disliked brand were used for test and confirmation. A “what if’ experimental approach was employed to test the applicability of dynamic HBT theory in OCB Model. The hypothesized OCB Model has been tested and validated. Consumers have been found to have separate views on the brand and the brand owner; and their responses to contrasting ethical and non-ethical news of the brand owner are different. Personality has been found to have an influence and two personality adapted models have been tested and validated. The actual results go beyond the prediction of the Balance Theory. Dominant triple positive balance mode, dominant negative balance mode, and mode of extreme antipathy have been found. It has been found that not all balanced modes are good for the brand. Contrary to Heider’s findings, simply liking may not necessarily lead to unit relation in the OCB Model.

Leadership and the negotiation of order in small groups

This thesis is focussed on the role differentiationhypothesis as it relates to small groups (Bales, 1958). The hypothesis is systematically examined, both conceptually and empirically, in the light of the Equilibrium Hypothesis (Bales, 1953) and the Negotiated Order Theory of leadership (e.g. Hosking, 1988). Chapter 1 sketches in a context for the research,which was stimulated by attempts during the 60s and 70s to organise small groups without leaders (the leaderless group, based on isocratic principles). Chapter 2 gives a conceptual and developmental overview of Bales' work, concentrating on the Equilibrium Hypothesis. It is argued that Bales' conceptual approach, if developed, can potentially integrate the disparate small groups and leadership literatures. Chapters 3 and 4 examine the concepts `group', `leader' and `leadership' in terms of the Negotiated Order perspective. In chapter 3 it is argued that two aspects of the concept group need to be taken separately into account; physical attributes and social psychological aspects (the metaphysical glue). It is further argued that a collection of people becomes a group only when they begin to establish a shared sense of social order. In chapter 4 it is argued that leadership is best viewed as a process of negotiation between those who influence and those who are influenced, in the context of shared values about means and ends. It is further argued that leadership is the process by which a shared sense of social order is established and maintained, thus linking the concepts `leadership' and `group' in a single formulation. The correspondences with Bales' approach are discussed at the end of the chapter. Chapters 5 to 8 present a detailed critical description and evaluation of the empirical work which claims to show role differentiation or test the hypothesis, both Bales original work and subsequent studies. It is argued here, that the measurement and analytical procedures adopted by Bales and others, in particular the use of simple means as summaries of group structures, are fundamentally flawed, and that role differentiation in relation to particular identifiable groups has not been demonstrated clearly anywhere in the literature. Chapters 9 to 13 present the empirical work conducted for the thesis. 18 small groups are examined systematically for evidence of role differentiation using an approach based on early sociometry (Moreno, 1934). The results suggest that role differentiation, as described by Bales, does not occur as often as is implied in the literature, and not equivocally in any case. In particular structures derived from Liking are typically distributed or weak. This suggests that one of Bales' principal findings, that Liking varies independently of his other main dimensions, is the product of statistical artifact. Chapter 14 presents a general summary of results and presents some considerations about future research.

The 'Healthy Passport' intervention with older people in an English urban environment:effects of incentives and peer-group organisers in promoting healthy living

This paper reports the evaluation of the effectiveness of incentives (viz. points and prizes) and of peer-group organisers ('older people's champions') in the outcomes of a health-improvement programme for people aged 50 + years in a multi-ethnic district of the West Midlands, England. Health promotion activities Were provided, and adherence, outcome variables and barriers to adherence were assessed over six months, using a `passport' format. Those aged in the fifties and of Asian origin Were under represented, but people of Afro-Caribbean origin were well represented and proportionately most likely to stay in the project. Those of greater age and With more illness were most likely to drop out. There were significant improvements in exercise, diet and the uptake of influenza vaccines and eyesight tests, but slighter improvements in wellbeing. Positive outcomes related to the incentives and to liking the format. The number of reported barriers was associated with lower involvement and lack of change, as was finding activities too difficult, the level of understanding, and transport and mobility problems, but when these were controlled, age did not predict involvement. Enjoying the scheme was related to positive changes, and this was associated with support from the older people's champions.

Modelling the underlying principles of human aesthetic preference in evolutionary art

Our understanding of creativity is limited, yet there is substantial research trying to mimic human creativity in artificial systems and in particular to produce systems that automatically evolve art appreciated by humans. We propose here to study human visual preference through observation of nearly 500 user sessions with a simple evolutionary art system. The progress of a set of aesthetic measures throughout each interactive user session is monitored and subsequently mimicked by automatic evolution in an attempt to produce an image to the liking of the human user.

Peer and friend influences on children's eating

Peers and friends are perceived as important role models for the formation of children's attitudes and behaviours. A wealth of research has aimed to establish the contribution of peers and friends to children's developing eating behaviours, and their attitudes towards eating. This review describes and evaluates such research. Experimental research examining peer modelling of food consumption and liking is reviewed, and several individual child factors that are suggested to make children more or less receptive to peer and friend influences are discussed. The influence of children's perceptions of their peers' and friends' eating behaviours upon their own eating practices is also explored. The benefits of future longitudinal research to improve understanding of peer and friend influences on children's eating are emphasized. © 2013 John Wiley & Sons Ltd.

Consumer engagement with self-expressive brands:brand love and WOM outcomes

Purpose: The purpose of this paper is to explore attitudes of consumers who engage with brands through Facebook "likes". It explores the extent to which these brands are self-expressive and examines the relationship between brand "liking" and brand outcomes. Brand outcomes include brand love and advocacy, where advocacy incorporates WOM and brand acceptance. Design/methodology/approach: Findings are presented from a survey of Facebook users who engage with a brand by "liking" it. Findings: Brands "liked" are expressive of the inner or social self. The study identifies a positive relationship between the self-expressive nature of brands "liked" and brand love. Consumers who engage with inner self-expressive brands are more likely to offer WOM for that brand. By contrast, consumers who engage with socially self-expressive brands are more likely to accept wrongdoing from a brand. Research limitations/implications: The research is exploratory and is limited to consumers who are engaged with a brand through "liking" it on the Facebook social network. Practical implications: The study offers suggestions for managers seeking to enhance brand engagement through Facebook "liking", and to encourage positive brand outcomes (such as WOM) among consumers already engaged with a brand on Facebook. Originality/value: This paper provides new insights into consumer brand engagement evidenced through Facebook "liking". It charts the relationship between "liked" self-expressive brands and brand love. Distinctions are drawn between brand outcomes among consumers who "like" for socially self-expressive reasons, and consumers who are brand engaged by "liking" to express their inner selves. © Emerald Group Publishing Limited.

Drinking while thirsty can lead to conditioned increases in consumption

A within-subject design was used to test whether repeatedly drinking a novel-flavoured and coloured drink while thirsty would influence subsequent liking for or consumption of that drink, compared to a different flavoured and coloured drink repeatedly consumed while less thirsty. Each participant was given 300 ml of one flavoured drink (H) after consuming a high salt meal (5.27 g of salt), and 300 ml of another flavoured drink (L) after consuming a low salt meal (1.27 g of salt). Participants had 4 sessions with each meal-type/drink combination, in an intermixed order. Pre- and post-training assessments of the drinks were conducted to determine the impact of the training regime on pleasantness and perceived thirst-quenching effect of the drinks. The final session included a choice test, and ad libitum access to the chosen drink, after either a high or low salt meal. In this final choice session, people drank almost twice as much H as L; however, there were no differential effects of past training on rated liking or choice. The increased consumption of H might reflect greater liking for H which was not detected by the rating scales; or it might reflect the learning of greater "conditioned thirst" in response to the flavour of H. © 2002 Elsevier Science Ltd.

'Why don't you try it again?' A comparison of parent led, home based interventions aimed at increasing children's consumption of a disliked vegetable

Previous research suggests that the use of modelling and non-food rewards may be effective at increasing tasting, and consequential liking and acceptance, of a previously disliked food. Although successful school-based interventions have been developed, there is a lack of research into home-based interventions using these methods. This study aimed to develop and investigate the efficacy of a parent led home-based intervention for increasing children's acceptance of a disliked vegetable. A total of 115 children aged 2-4 years were allocated to one of four intervention groups or to a no-treatment control. The four intervention conditions were: repeated exposure; modelling and repeated exposure; rewards and repeated exposure; or modelling, rewards and repeated exposure. Children in all of the intervention conditions were exposed by a parent to daily offerings of a disliked vegetable for 14 days. Liking and consumption of the vegetable were measured pre and post-intervention. Significant increases in post-intervention consumption were seen in the modelling, rewards and repeated exposure condition and the rewards and repeated exposure condition, compared to the control group. Significant post-intervention differences in liking were also found between the experimental groups. Liking was highest (>60%) in the modelling, rewards and repeated exposure group and the rewards and repeated exposure group, intermediate (>26%) in the modelling and repeated exposure and repeated exposure groups, and lowest in the control group (10%). Parent led interventions based around modelling and offering incentives may present cost efficient ways to increase children's vegetable consumption.

Impact of Vegetable Preparation Method and Taste-Test on Vegetable Preference for First Grade Children in the United States

How children rate vegetables may be influenced by the preparation method. The primary objective of this study was for first grade students to be involved in a cooking demonstration and to taste and rate vegetables raw and cooked. First grade children of two classes (N= 52: 18 boys and 34 girls (approximately half Hispanic) that had assented and had signed parental consent participated in the study. The degree of liking a particular vegetable was recorded by the students using a hedonic scale of five commonly eaten vegetables tasted first raw (pre-demonstration) and then cooked (post-demonstration). A food habit questionnaire was filled out by parents to evaluate their mealtime practices and beliefs about their child’s eating habits. Paired sample t-tests revealed significant differences in preferences for vegetables in their raw and cooked states. Several mealtime characteristics were significantly associated with children’s vegetable preferences. Parents who reported being satisfied with how often the family eats evening meals together were more likely to report that their child eats adequate vegetables for their health (p=0.026). Parents who stated that they were satisfied with their child’s eating habits were more likely to report that their child was trying new foods (p<.001). Cooking demonstrations by nutrition professionals may be an important strategy that can be used by parents and teachers to promote vegetable intake. It is important that nutrition professionals provide guidance to encourage consumption of vegetables for parents so that they can model the behavior of healthy food consumption to their children.
