The role of humor in television advertisement: A study regarding Portuguese consumers’ emotions and reactions

The purpose of this study is to explore the humorous side of television advertisement and its impact on Portuguese consumers’ hearts, minds and wallets. Both qualitative (through in-depth interviews) and quantitative (through an on-line survey and subsequent statistical data analysis) methods were used, guaranteeing a more consistent, strong and valid research. Twenty-five interviews with randomly chosen consumers were conducted face-to-face and three interviews via e-mail with marketers and television advertisers were performed in order to explore profoundly the subject. Moreover, 360 people have answered the on-line survey. Through the analysis of the data collected humor perception was found to be positively correlated with persuasion and intention to purchase the product; intention to share the advert; message comprehension; product liking and development of positive feelings towards the brand and brand credibility variables. The main implication of these findings relies on the fact that humor in advertising is able to boost its effectiveness.

Potencial das atividades desenvolvidas por docentes de música para a perda auditiva induzida por ruído

A perda auditiva por exposição ao ruído é um problema de saúde ocupacional, não reconhecido nas escolas de música. Em Portugal, a legislação relativa a ruído ocupacional não possui indicações específicas para músicos, existindo apenas um código de conduta europeu, proveniente da Diretiva 2003/10/CE que estabelece as orientações gerais relativas a como devem ser protegidos do ruído músicos e trabalhadores de setores de entretenimento. Avaliou-se o nível sonoro contínuo equivalente (LAeq), individualmente no decorrer das atividades letivas, o que permitiu determinar o nível exposição pessoal diária ao ruído (Lex,8h) de 20 docentes de música. Paralelamente, os docentes preencheram um questionário relativo a fatores intrínsecos e individuais e todos efetuaram audiogramas tonais simples. Os dados recolhidos foram estatisticamente tratados através do programa Statistical Package for Social Sciences (SPSS) versão 21. Existem atividades letivas que implicam níveis de exposição pessoal diária ao ruído superiores ao nível de ação inferior (25%), pelo que se devem adotar medidas para sensibilizar e alertar os docentes para a adoção de medidas de proteção. A atividade dos docentes expostos a níveis de exposição pessoal diária mais elevados correspondeu a aulas de grupo e a aulas individuais, com utilização de instrumentos musicais direcionais. A manifestação de sintomatologia relevante relativa a perda auditiva (audição de zumbidos, dificuldades de perceção do diálogo e dificuldade em adormecer) e a evolução da surdez profissional, não parecem estar diretamente relacionadas com os níveis de exposição pessoal diária ao ruído nem atividades com exposição ao ruído desenvolvidas nos tempos livres.

Comparación: injerto libre o cierre primario más lente de contacto, en resección de tumores de conjuntiva limbar

INTRODUCCION: Existe controversia en cuanto a la técnica quirúrgica para el manejo de tumores del limbo conjuntival. El uso de cierre primario con uso de lente de contacto puede ofrecer una mejor cicatrización y tener ventajas adicionales sobre la técnica tradicional con el uso de plastia. OBJETIVOS: Comparar los resultados en cuanto a grado de dolor, picadas, prurito, porcentaje de epitelización y cicatrización, comodidad del paciente, grado de quemosis y tiempo de retorno a actividades diarias en ambas técnicas quirúrgicas. MATERIALES Y METODOS: Experimento clínico controlado aleatorizado en dos grupos: Al primer grupo se le realizó cirugía de resección de la lesión más plastia. Al segundo grupo se le practicó la resección de la lesión cierre primario y lente de contacto. El seguimiento se realizó al primer y cuarto día, y cada semana durante el primer mes de postoperatorio. Se utilizó el SPSS 20.0 ® para análisis estadístico de datos y se utilizó estadística no paramétrica. RESULTADOS: Se conto con 10 pacientes por grupo. El dolor y porcentaje de cicatrización al primer día postoperatorio fueron mayores en el grupo usando lente de contacto (p=0.048). Al cuarto día postquirúrgico se encontró un mayor porcentaje de cicatrización en el grupo usando lente de contacto. (p=0.075). CONCLUSIONES: El cierre por afrontamiento con uso de lente de contacto mostró dolor y picadas mayores al primer y cuarto día postoperatorio. Pero la epitelización y cicatrización fueron tempranas con un retorno corto a actividades cotidianas.

Nitrogen flows from European watersheds to coastal marine waters

Nitrogen flows from European watersheds to coastal marine waters Executive summary Nature of the problem • Most regional watersheds in Europe constitute managed human territories importing large amounts of new reactive nitrogen. • As a consequence, groundwater, surface freshwater and coastal seawater are undergoing severe nitrogen contamination and/or eutrophication problems. Approaches • A comprehensive evaluation of net anthropogenic inputs of reactive nitrogen (NANI) through atmospheric deposition, crop N fixation,fertiliser use and import of food and feed has been carried out for all European watersheds. A database on N, P and Si fluxes delivered at the basin outlets has been assembled. • A number of modelling approaches based on either statistical regression analysis or mechanistic description of the processes involved in nitrogen transfer and transformations have been developed for relating N inputs to watersheds to outputs into coastal marine ecosystems. Key findings/state of knowledge • Throughout Europe, NANI represents 3700 kgN/km2/yr (range, 0–8400 depending on the watershed), i.e. five times the background rate of natural N2 fixation. • A mean of approximately 78% of NANI does not reach the basin outlet, but instead is stored (in soils, sediments or ground water) or eliminated to the atmosphere as reactive N forms or as N2. • N delivery to the European marine coastal zone totals 810 kgN/km2/yr (range, 200–4000 depending on the watershed), about four times the natural background. In areas of limited availability of silica, these inputs cause harmful algal blooms. Major uncertainties/challenges • The exact dimension of anthropogenic N inputs to watersheds is still imperfectly known and requires pursuing monitoring programmes and data integration at the international level. • The exact nature of ‘retention’ processes, which potentially represent a major management lever for reducing N contamination of water resources, is still poorly understood. • Coastal marine eutrophication depends to a large degree on local morphological and hydrographic conditions as well as on estuarine processes, which are also imperfectly known. Recommendations • Better control and management of the nitrogen cascade at the watershed scale is required to reduce N contamination of ground- and surface water, as well as coastal eutrophication. • In spite of the potential of these management measures, there is no choice at the European scale but to reduce the primary inputs of reactive nitrogen to watersheds, through changes in agriculture, human diet and other N flows related to human activity.

Influence of NaHCO(3) Powder on Translucency of Microfilled Composite Resin Immersed in Different Mouthrinses

The regular use of mouthrinses, particularly when combined with the use of air-powder polishing, could affect the appearance of tooth-colored restorations. The current study sought to evaluate the effect of NaHCO(3) powder on translucency of a microfilled composite resin immersed in different mouthrinses, at distinct evaluation periods. Eighty disk-shaped specimens of composite resin (Durafill VS, Heraeus Kulzer GmbH & Co. KG, Hanau, Germany) were prepared. The composite specimens were then randomly allocated into two groups according to the surface treatment: exposure to NaHCO(3) powder (10 seconds) or nonexposure, and they were randomly assigned into four subgroups, according to the mouthrinses employed (N = 10): Periogard (Colgate/Palmolive, Sao Bernardo do Campo, SP, Brazil), Cepacol (Aventis Pharma, Sao Paulo, SP, Brazil), Plax (Colgate/Palmolive), and distilled water (control group). The samples were immersed for 2 minutes daily, 5 days per week, over a 4-month test period. Translucency was measured with a transmission densitometer at seven evaluation periods. Statistical analyses (analysis of variance and Tukey`s test) revealed that: distilled water presented higher translucency values (86.72%); Periogard demonstrated the lowest translucency values (72.70%); and Plax (74.05%) and Cepacol (73.32%) showed intermediate translucency values, which were statistically similar between them (p > 0.01). NaHCO(3) air-powder polishing increased the changes in translucency associated with the mouthrinses. Air-powder polishing alone had no effect on material translucency. Translucency percent was gradually decreased from 1 week of immersion up to 4 months. It may be concluded that the NaHCO(3) powder and the tested mouthrinses have affected the translucency of microfilled composite resin, according to the tested time. CLINICAL SIGNIFICANCE During the last decade, the demand for composite resin restorations has grown considerably, however, controversy persists regarding the effect of surface roughness on color stability.

Site-directed mutagenesis and structural modeling of Coq10p indicate the presence of a tunnel for coenzyme Q6 binding

Coq10p is a protein required for coenzyme Q function, but its specific role is still unknown. It is a member of the START domain superfamily that contains a hydrophobic tunnel implicated in the binding of lipophilic molecules. We used site-directed mutagenesis, statistical coupling analysis and molecular modeling to probe structural determinants in the Coq10p putative tunnel. Four point mutations were generated (coq10-K50E, coq10-L96S, coq10-E105K and coq10-K162D) and their biochemical properties analysed, as well as structural consequences. Our results show that all mutations impaired Coq10p function and together with molecular modeling indicate an important role for the Coq10p putative tunnel.

Observational constraints on the dark energy and dark matter mutual coupling

We examine different phenomenological interaction models for Dark Energy and Dark Matter by performing statistical joint analysis with observational data arising from the 182 Gold type la supernova samples, the shift parameter of the Cosmic Microwave Background given by the three-year Wilkinson Microwave Anisotropy Probe observations, the baryon acoustic oscillation measurement from the Sloan Digital Sky Survey and age estimates of 35 galaxies. Including the time-dependent observable, we add sensitivity of measurement and give complementary results for the fitting. The compatibility among three different data sets seem to imply that the coupling between dark energy and dark matter is a small positive value, which satisfies the requirement to solve the coincidence problem and the second law of thermodynamics, being compatible with previous estimates.

Reaction mechanisms in the (6)Li+(59)Co system

The reactions induced by the weakly bound (6)Li projectile interacting with the intermediate mass target (59)Co were investigated. Light charged particles singles and alpha-d coincidence measurements were performed at the near barrier energies E(lab) = 17.4, 21.5, 25.5 and 29.6 MeV. The main contributions of the different competing mechanisms are discussed. A statistical model analysis. Continuum-Discretized Coupled-Channels (CDCC) calculations and two-body kinematics were used as tools to provide information to disentangle the main components of these mechanisms. A significant contribution of the direct breakup was observed through the difference between the experimental sequential breakup cross section and the CDCC prediction for the non-capture breakup cross section.

On Occurrence Of Plagiarism In Published Computer Science Thesis Reports At Swedish Universities

In recent years, it has been observed that software clones and plagiarism are becoming an increased threat for one?s creativity. Clones are the results of copying and using other?s work. According to the Merriam – Webster dictionary, “A clone is one that appears to be a copy of an original form”. It is synonym to duplicate. Clones lead to redundancy of codes, but not all redundant code is a clone.On basis of this background knowledge ,in order to safeguard one?s idea and to avoid intentional code duplication for pretending other?s work as if their owns, software clone detection should be emphasized more. The objective of this paper is to review the methods for clone detection and to apply those methods for finding the extent of plagiarism occurrence among the Swedish Universities in Master level computer science department and to analyze the results.The rest part of the paper, discuss about software plagiarism detection which employs data analysis technique and then statistical analysis of the results.Plagiarism is an act of stealing and passing off the idea?s and words of another person?s as one?s own. Using data analysis technique, samples(Master level computer Science thesis report) were taken from various Swedish universities and processed in Ephorus anti plagiarism software detection. Ephorus gives the percentage of plagiarism for each thesis document, from this results statistical analysis were carried out using Minitab Software.The results gives a very low percentage of Plagiarism extent among the Swedish universities, which concludes that Plagiarism is not a threat to Sweden?s standard of education in computer science.This paper is based on data analysis, intelligence techniques, EPHORUS software plagiarism detection tool and MINITAB statistical software analysis.

Evidências empíricas das competências profissionais críticas do CIO brasileiro

The primary objective of this work is to obtain a CIO¿s Critical Competencies model which could be applied to Brazilian CIO. This study was conducted by an explanatory research in a quantitative approach. Theoretical studies were done to understand CIO¿s environment, his identity, his career and organizational relationship. The analysis was based on six CIO¿s competencies models which describe how this professional could have a better performance. The intention of this approach was to provide a better understanding about the research problem. Then a meta-model was done as well as a survey. Once applied on Internet, the survey had 111 valid respondents, all Brazilian CIOs. To obtain the final model statistical factorial analysis was applied to the answers. Each identified factor in the model corresponds to a critical competency for Brazilian CIO. The model was submitted to hypotheses tests trying to establish what is the relation between each resultant factor and the time in the role for each respondent as well as his company size. This study has emerged a CIO critical competencies model to the Brazilian CIO, regarding his good performance.

Análise da resistência a sistemas de informação: a percepção dos gestores de tecnologia da informação acerca de sistemas ERP

Este trabalho visa obter e verificar empiricamente um meta-modelo que possa apoiar e aprofundar a compreensão do fenômeno da resistência a sistemas de informação. Tratase de uma pesquisa explanatória e quantitativa na qual faz-se, por meio de uma extensa revisão da literatura mundial, o levantamento e consolidação das principais teorias e modelos existentes sobre o tema. Dessa forma, buscando obter um melhor entendimento do problema de pesquisa, propõe-se um meta-modelo de fatores pertinentes ao comportamento de resistência a sistemas de informação. Neste modelo, considera-se um conjunto de aspectos que, embora já abordados anteriormente, em sua maior parte ainda não haviam sido testados empiricamente, quais sejam: (i) as características idiossincráticas dos indivíduos, (ii) os aspectos técnicos inerentes aos sistemas de informação, (iii) as características da interação sócio-técnica, (iv) as características da interação de poder e políticas e, finalmente, (v) as características das organizações nas quais a tecnologia e o homem estão inseridos e interagem entre si. O instrumento de pesquisa utilizado no trabalho foi um questionário estruturado, aplicado via Internet, com suas questões contextualizadas quanto aos sistemas de gestão empresarial ERPs: Enterprise Resource Planning Systems. Obteve-se um total de 169 respondentes, considerando-se uma amostra composta exclusivamente por gestores de tecnologia da informação (TI) brasileiros e que tenham vivenciado pelo menos uma experiência de implantação de sistemas ERP ao longo de suas carreiras. Uma vez realizada a coleta dos dados, foram empregados testes estatísticos relativos à análise fatorial, visando alcançar um modelo definitivo. A partir do novo modelo encontrado, por meio da validação proporcionada pela análise fatorial, cada fator identificado representou uma causa para o comportamento de resistência a sistemas de informação. Por fim, testou-se também hipóteses a partir do novo modelo identificado, verificando-se as relações entre a percepção direta dos gestores quanto à resistência e os diversos fatores considerados relevantes para a explicação deste comportamento. Como resultado do estudo, consolidou-se um modelo de análise do comportamento de resistência a sistemas de informação, baseado na percepção do gestor de TI e contextualizado nos sistemas ERPs.
