Análise de conteúdo verbal na solução de dificuldades de portadores de transtornos ansiosos

O entendimento do comportamento verbal é crucial para a análise de comportamentos disfuncionais tratados em terapia de base analítico-comportamental. Pesquisas com comportamento verbal no contexto clínico, têm apontado a eficácia da utilização do comportamento verbal e gerado procedimentos de intervenção na solução de problemas. O reforçamento de auto-relatos, como função de um arranjo de contingências de reforçamento, tem mostrado que o relato verbal é um meio válido para alterar comportamento não verbal fora da situação terapêutica. O objetivo do presente estudo é demonstrar a utilidade de um procedimento de arranjo de contingências verbais pelo terapeuta por meio da sistematização de conteúdo verbal do cliente e sua reapresentação por escrito, para a solução de dificuldades de indivíduos que apresentam transtorno ansioso em situação de interação terapêutica. Sendo expostas ao seu próprio comportamento verbal, sistematizado na forma de categorias por conteúdo de verbalização, foi possível a duas participantes deste estudo caracterizarem suas dificuldades, identificando e descrevendo contingências ambientais relacionadas com seu comportamento indesejado e conseqüentemente a descreverem propostas de solução dessas dificuldades. Discutiu-se como a exposição ao conteúdo sistematizado do seu próprio relato verbal alterou o relato verbal e o comportamento-queixa.

Contribution to economic evaluation of systems that value animal welfare at farm

The demand for "welfare friendly" products increases as public conscience and perception on livestock production systems grow. The public and policy-makers demand scientific information for education and to guide decision processes. This paper describes some of the last decade contributions made by scientists on the technical, economical and market areas of farm animal welfare. Articles on animal welfare were compiled on the following themes: 1) consumer behavior, 2) technical and economical viability, 3) public regulation, and 4) private certification policies. Most studies on the economic evaluation of systems that promote animal welfare involved species destined to produce export items, such as eggs, beef and pork. Few studies were found on broilers, dairy cows and fish, and data regarding other species, such as horses, sheep and goats were not found. Scientists understand that farm animal welfare is not only a matter of ethics, but also an essential tool to gain and maintain markets. However, it is unfortunate that little attention is paid to species that are not economically important for exports. Studies that emphasize on more humane ways to raise animals and that provide economic incentives to the producer are needed. An integrated multidisciplinary approach is necessary to highlight the benefits of introducing animal welfare techniques to existing production systems.

COMMUNITY OF ORIGIN EFFECTS ON VIRTUAL BRAND COMMUNITIES PARTICIPANT

The question about the effectiveness of companies in maintaining their own communities versus benefiting from the ones owned by consumers remains open. We examine differences between firm-managed and customer-managed brand communities regarding the impact of perceived psychographic homogeneity, availability of virtual avenues and relationship with the brand on the community's influence on members and the assessments and intentions of community participants. Data were obtained from 555 respondents in two leading Microsoft XBOX brand communities in Brazil. Results indicate that management of the community of origin is the moderator of all considered relationships. Also, the most favorable effects for the company occur in the community that is not directly controlled and managed by the company itself. Brand loyalty, however, is higher for members of the official brand community. Guidelines on how companies can benefit from consumer-managed communities are discussed.

In defence of modeling simultaneity for a correct approximation of cultural aspects: implications for food consumers studies with latent variables

Dealing with latent constructs (loaded by reflective and congeneric measures) cross-culturally compared means studying how these unobserved variables vary, and/or covary each other, after controlling for possibly disturbing cultural forces. This yields to the so-called ‘measurement invariance’ matter that refers to the extent to which data collected by the same multi-item measurement instrument (i.e., self-reported questionnaire of items underlying common latent constructs) are comparable across different cultural environments. As a matter of fact, it would be unthinkable exploring latent variables heterogeneity (e.g., latent means; latent levels of deviations from the means (i.e., latent variances), latent levels of shared variation from the respective means (i.e., latent covariances), levels of magnitude of structural path coefficients with regard to causal relations among latent variables) across different populations without controlling for cultural bias in the underlying measures. Furthermore, it would be unrealistic to assess this latter correction without using a framework that is able to take into account all these potential cultural biases across populations simultaneously. Since the real world ‘acts’ in a simultaneous way as well. As a consequence, I, as researcher, may want to control for cultural forces hypothesizing they are all acting at the same time throughout groups of comparison and therefore examining if they are inflating or suppressing my new estimations with hierarchical nested constraints on the original estimated parameters. Multi Sample Structural Equation Modeling-based Confirmatory Factor Analysis (MS-SEM-based CFA) still represents a dominant and flexible statistical framework to work out this potential cultural bias in a simultaneous way. With this dissertation I wanted to make an attempt to introduce new viewpoints on measurement invariance handled under covariance-based SEM framework by means of a consumer behavior modeling application on functional food choices.

Increasing Utilization of US Electric Grids via Smart Technologies: Integration of Load Management, Real Time Pricing, Renewables, EVs and Smart Grid Sensors

Electric power grids throughout the world suffer from serious inefficiencies associated with under-utilization due to demand patterns, engineering design and load following approaches in use today. These grids consume much of the world’s energy and represent a large carbon footprint. From material utilization perspectives significant hardware is manufactured and installed for this infrastructure often to be used at less than 20-40% of its operational capacity for most of its lifetime. These inefficiencies lead engineers to require additional grid support and conventional generation capacity additions when renewable technologies (such as solar and wind) and electric vehicles are to be added to the utility demand/supply mix. Using actual data from the PJM [PJM 2009] the work shows that consumer load management, real time price signals, sensors and intelligent demand/supply control offer a compelling path forward to increase the efficient utilization and carbon footprint reduction of the world’s grids. Underutilization factors from many distribution companies indicate that distribution feeders are often operated at only 70-80% of their peak capacity for a few hours per year, and on average are loaded to less than 30-40% of their capability. By creating strong societal connections between consumers and energy providers technology can radically change this situation. Intelligent deployment of smart sensors, smart electric vehicles, consumer-based load management technology very high saturations of intermittent renewable energy supplies can be effectively controlled and dispatched to increase the levels of utilization of existing utility distribution, substation, transmission, and generation equipment. The strengthening of these technology, society and consumer relationships requires rapid dissemination of knowledge (real time prices, costs & benefit sharing, demand response requirements) in order to incentivize behaviors that can increase the effective use of technological equipment that represents one of the largest capital assets modern society has created.

The "Image" of the Pharaoh in Judahite and Israelite Society According to the Glyptic Evidence

Among the many thousand scarabs, scaraboids and other stamp-seal amulets unearthed in Iron Age contexts in Cis- and Transjordan, there are many such seals showing royal Egyptian imagery on their bases. Focusing mainly on Pharaonic motifs, the paper aims to catalogue the principal iconemes, to trace their development throughout the Iron Ages and to extrapolate their significance vis-à-vis the contemporary glyptic assemblages. As will be shown, the royal imagery of the Egyptian king underwent considerable changes during pre-monarchic and monarchic times in Israel/Judah. This allows – to some extent – deducing the perception of the ‘image’ of the Egyptian king in this part of the Southern Levant at the close of the second and during the first centuries of the first millennium BCE. While the local seal production not only vividly copied earlier and contemporary Egyptian prototypes, it also developed idiosyncratic ‘Pharaonic’ motifs that were produced for the local market. On the other hand, imported Egyptian glyptic goods – such as scarabs and other amulet types – reveal further facets of the consumer behavior. They, too, shed light upon the ideological and religious preferences of the local population and illuminate the development of the vernacular attitude towards the Pharaonic symbols of power – including their obvious political and sacred connotations.
