Foi bom para você? Uma compara??o do valor hed?nico de compras feitas em diferentes tipos de varejistas
Hernandez, José Mauro da Costa;
RAM. Revista de Administra??o Mackenzie , 2009, DOI: 10.1590/S1678-69712009000200002
Abstract: this study compares, in three distinct studies, the hedonic value of purchases made at different retail merchants. in the first study it is compared the hedonic shopping value of purchases made at e-stores and brick-and-mortar merchants; the second compares large and small malls, and the third compares specialty stores and superstores. in general, the conclusion is that hedonic shopping value cannot be attributed to specific merchant classes since the main effects, whenever present, were of little significance. it is suggested that future studies should focus on looking into specific retail merchant characteristics and how they interact with individual characteristics in the creation of hedonic value.
Um estudo empírico sobre os benefícios da procura e do uso da Internet como fonte de informa??es
Hernandez, José Mauro da Costa;
Revista de Administra??o Contemporanea , 2002, DOI: 10.1590/S1415-65552002000300009
Abstract: this study replicates previous studies focusing on consumer information search benefits and introduces the internet as a source of information to investigate whether its users obtained more benefits in the purchase of new automobile than non-users. the results, besides allowing the identification of a large set of search determinants, also permitted to conclude that buyers that used the internet as a source of information spent more time searching than buyers that did not use the internet. this finding is likely to result from the different search profiles of both groups (internet users are younger, more educated, and have higher income, characteristics usually associated with more search). when both groups were analyzed together, it was found that time spent on search was not positively associated with higher discounts in the purchase of the new automobile. however, when the two groups were separated and analyzed, it was found that time spent on search was positively associated with higher discounts for the group of internet users but not for the group of non-users. findings are discussed and modifications in the theoretical model are suggested.

Revista de Administra??o Mackenzie , 2009,
Abstract: Este estudo compara, por meio de três pesquisas distintas, o valor hed nico decompras feitas em diferentes tipos de varejistas. Na primeira pesquisa, comparouseo valor hed nico de compras feitas em lojas eletr nicas e lojas tradicionais; nasegunda, foram comparados os valores hed nicos de compras feitas em shoppingcenters de diferentes tamanhos; e na última comparou-se o valor hed nico de comprasfeitas em lojas de especialidade e superlojas. De forma geral, a conclus o éque o valor hed nico n o pode ser atribuído a classes específicas de varejistas,uma vez que os efeitos principais, quando presentes, foram pouco significativos.Sugere-se que futuros estudos concentrem-se em determinadas características dosvarejistas e na intera o destas características com características individuais nacria o do valor hed nico.
Single-Phase Velocity Determination Based in Video and Sub-Images Processing: An Optical Flow Method Implemented with Support of a Programmed MatLab Structured Script  [PDF]
Andreas Nascimento, Edson Da Costa Bortoni, José Luiz Gon?alves, Pedro Antunes Duarte, Mauro Hugo Mathias
Journal of Software Engineering and Applications (JSEA) , 2015, DOI: 10.4236/jsea.2015.86029
Abstract: Important in many different sectors of the industry, the determination of stream velocity has become more and more important due to measurements precision necessity, in order to determine the right production rates, determine the volumetric production of undesired fluid, establish automated controls based on these measurements avoiding over-flooding or over-production, guaranteeing accurate predictive maintenance, etc. Difficulties being faced have been the determination of the velocity of specific fluids embedded in some others, for example, determining the gas bubbles stream velocity flowing throughout liquid fluid phase. Although different and already applicable methods have been researched and already implemented within the industry, a non-intrusive automated way of providing those stream velocities has its importance, and may have a huge impact in projects budget. Knowing the importance of its determination, this developed script uses a methodology of breaking-down real-time videos media into frame images, analyzing by pixel correlations possible superposition matches for further gas bubbles stream velocity estimation. In raw sense, the script bases itself in functions and procedures already available in MatLab, which can be used for image processing and treatments, allowing the methodology to be implemented. Its accuracy after the running test was of around 97% (ninety-seven percent); the raw source code with comments had almost 3000 (three thousand) characters; and the hardware placed for running the code was an Intel Core Duo 2.13 [Ghz] and 2 [Gb] RAM memory capable workstation. Even showing good results, it could be stated that just the end point correlations were actually getting to the final solution. So that, making use of self-learning functions or neural network, one could surely enhance the capability of the application to be run in real-time without getting exhaust by iterative loops.
Um estudo empírico dos determinantes da ado??o de Internet Banking entre n?o usuários brasileiros
Hernandez, José Mauro da Costa;Mazzon, José Afonso;
Revista de Administra??o Contemporanea , 2008, DOI: 10.1590/S1415-65552008000500002
Abstract: this study investigates the determinants of internet banking adoption among brazilians non-users. to accomplish this objective, the study proposes a model built with constructs gathered from the most known models of new technology adoption found in the marketing literature. the model was tested among a sample of 292 people and the results show that the effects of eight variables were significant in determining the intention to adopt internet banking. they are compatibility with lifestyle, subjective norm, self-efficacy, image, relative advantage of security and privacy, relative advantage of control, trialability, and technological support. by the other side, none of the individual characteristics included in the model were significant. the major contribution of the study is the proposal of a comprehensive, simple, and easily implementable model. the study concludes by pointing some managerial implications, limitations, and suggestions for future studies.
Development-based trust: proposing and validating a new trust measurement model for buyer-seller relationships
Hernandez, José Mauro da Costa;Santos, Claudia Cincotto dos;
BAR. Brazilian Administration Review , 2010, DOI: 10.1590/S1807-76922010000200005
Abstract: this study proposes and validates a trust measurement model for buyer-seller relationships. baptized as development-based trust, the model encompasses three dimensions of trust: calculus-based, knowledge-based and identification-based. in addition to recognizing that trust is a multidimensional construct, the model also assumes that trust can evolve to take on a different character depending on the stage of the relationship. in order to test the proposed model and compare it to the characteristic-based trust measurement model, the measure most frequently used in the buyer-seller relationship literature, data were collected from 238 clients of an it product wholesaler. the results show that the scales are valid and reliable and the proposed development-based trust measurement model is superior to the characteristic-based trust measurement model in terms of its ability to explain certain variables of interest in buyer-seller relationships (long-term relationship orientation, information sharing, behavioral loyalty and future intentions). implications for practice, limitations and suggestions for future studies are discussed.
Valores de compra hed?nico e utilitário: os antecedentes e as rela??es com os resultados do varejo
Teixeira, Jo?o Marques;Hernandez, José Mauro da Costa;
REAd. Revista Eletr?nica de Administra??o (Porto Alegre) , 2012, DOI: 10.1590/S1413-23112012000100005
Abstract: induced by the recent debate regarding the influence that the store environment can have on consumers and by the massive amount of resources that retailers have spent in order to create satisfied consumers, this study proposes a new model in which the relationship between store environment variables (physical environment, organization, assortment, and salesman service) and retail outcomes variables (satisfaction, repurchase intention, and word-of-mouth) is mediated by hedonic and utilitarian shopping values. to test the theoretical model, data were collected from the 399 respondents who purchased appliances at a store located in the city of s?o paulo, brazil. the results indicated that among the environmental variables of the store, only the assistance of salesman has positively influenced the values of hedonic and utilitarian shopping. hedonic shopping value influenced positively all the retail outcomes variables while utilitarian shopping value did not influence any of them. the results suggest that in this particular case, hedonic shopping value was much more important than utilitarian shopping value to determine purchase satisfaction, repurchase intention, and intention of word-of-mouth. the results also suggest the greater importance of salesman service in situations that the store environment is not especially attractive or different.
Resistência a mudan?a: uma revis?o crítica
Hernandez, José Mauro da Costa;Caldas, Miguel P.;

Abstract: when implementing changes and innovations, organizations often have to deal with resistance to change. maybe because few subjects pertaining to organizational transformation are so broadly and consistently covered in the popular literature, we may have been induced to believe we must know all about it. if we know so much, why resistance is still a major barrier to organizational transformation, and why so many change agents still strive to overcome it? in this article, we attempt to respond this question by questioning the predominant models of resistance and the assumptions of the several "recipe-oriented" approaches to deal with resistance in organizations. our understanding is that such "recipes" are not particularly helpful because they use a model of resistance to change that was built upon several questionable assumptions, according to which resistance is a) a "natural", inevitable fact; b) malignant to the organization; c) employee-driven; and d) collective. based on counter-assumptions to each of these widespread premises and on psychology of perception, a new model of individual resistance to change is proposed. the model represents the individual's perceptual process during organizational change, from exposure to stimuli until behavior adoption. the seven-stage model culminates in four possible outcomes: resistance, resistance overcoming, indecision, or change adoption. implications for theory and practice, limitations of the model and suggestions for future development are presented.

O Efeito da Marca na Negligência da Omiss o: uma Pesquisa Experimental
Evandro Luiz Lopes,Dirceu da Silva,José Mauro da Costa Hernandez
Revista de Administra??o Contemporanea , 2013,
Abstract: Omission negligence is characterized by the lack of sensibility regarding unmentioned or unknown information. This phenomenon is very recurring, since it is not rare that a consumer has to make a decision supported by a judgment formulated from incomplete information. Prior research indicated that people often cannot identify the absence of important information, which results in strong convictions being formed based on little consistent evidence. The main purpose of this work is to comprehend brand effects on omission negligence. Three experiments were conducted, involving 769 undergraduate students of business administration. Empiricalexperiments support the understanding that individuals with a low contextual cognitive level (non-experts) are insensitive to attribute omission and are also extremely positive when completing evaluations, even when there is no apparent reason for that. Upon comparing the experiments’ findings, it is understood that a recognized brand more incisively influences experts’ evaluation than non-experts’. Even though experts anchor their judgments in a more strict evaluation of available attributes, a recognized brand has a strong influence on the object’s general evaluation.
