Abstract

A computer program named DOTIG1 was developed for the study, in the time domain, of the interaction of transient electromagnetic pulses (EMP) with structures modelled by thin wires. The numerical procedure used is described and the results obtained with DOTIG1 are compared with those obtained, in the frequency domain, by other authors, using the Fourier transform. The comparison is specifically applied to the scattering cases from a simple stick model of an aircraft, from a wire cross in front of an infinite perfect conductor and from a junction of two wires with different radii.

Abstract

This paper describes a computer program DOTIG4, for the study in the time domain, of the interaction of transient electromagnetic pulses (EMP) with arbitrary perfect conducting (PEC) surfaces modelled by planar triangular patches. DOTIG4 is based on the solution of the Time Domain Electric Field Integral Equation (TD‐EFIE) by the method of moments (MoM) using a marching‐on‐in‐time procedure. The code is applied to transient scattering of several structures and to calculate the input impedance of several broadband antennas.

Abstract

Purpose

The purpose of the present study is to evaluate chocolate consumption effects with a non invasive metodology. There is evidence that the consumption of dark chocolate and cocoa with high flavonoid content could have positive effects on blood pressure (BP) and weight management (WM); however, there are complications at the moment of obtaining blood samples to evaluate on children at a primary school level.

Design/methodology/approach

A total of 54 healthy scholars were included; consumption of 70 per cent cacao dark chocolate was integrated into the daily snack during a 30-day period. Blood pressure, body fat, total content of polyphenols in urine and total antioxidant capacity of saliva were measured. The results obtained were divided in relation of two groups of students, A and B, with lesser or higher difficulties to WM in a self-assessment test; variables were then statistically evaluated.

Findings

Consumption of chocolate produced changes in the total content of polyphenols (from 5.6 to 6.8 µg/mL, p < 0.016) and salivary antioxidant capacity [(14.76 ± 5.4 and 16.14 ± 3.9) TEU nmol versus. t = 0; p < 0.029 and p < 0.001 at 15 and 30 days, respectively]. Group B, which presented higher difficulties concerning WM, presented a body fat reduction of about 0.63 per cent after chocolate consumption (p = 0.045) and a diastolic blood pressure reduction of −2.8 mm Hg in average (p < 0.025). A significant weight gain (p < 0.023) was observed only in Group A.

Research limitations/implications

Despite the reduced sensitivity of the non-invasive methodology, differences in urine and salivary content of polyphenols and antioxidant capacity suggest that the design used could be feasible, although extended studies are needed to corroborate it.

Originality/value

A non-invasive study for screening the potential health benefits of dark chocolate was assayed. The results suggest that dark chocolate consumption in children as part of the daily snack could be a complementary element in weight management and in prevention of future risk factors to chronic diseases.

Abstract

This chapter aims to understand the communication practices of CSR in technological environments, specifically corporate websites. It is important to know what are the dimensions of CSR most valued in online communication, what content is more widespread, and if there is dialogic communication between organizations and different stakeholders. It was used a quantitative method of analysis, using the expanded web content analysis. It was based on the study results of the 1,000 largest Portuguese companies published by the Economic Journal in 2014. The chapter includes the analysis of the best companies from 24 sectors of activity of Portugal. Portuguese organizations use their websites to communicate about CSR practices. A large majority of companies dedicate to these subjects a higher number of pages. The findings indicate that the issues disseminated are various, but the predominance content is related to environmental dimension. Results suggest a low level of dialogic dimension adoption. It is proposed a theoretical framework of online communication of CSR that integrates a set of indicators from three interlinked dimensions: the technical dimension, the informational dimension and dialogical dimension, considering the different kind of publics and the different practice areas inherent to CSR. This framework is a contribution to the deepening of knowledge and understanding of online communication of CSR practices, on the perspective of public relations theory. It has practical implications to communication, because it proposes guidelines that should be considered in an effective online communication of CSR in organizations of various sectors of activity in Portugal. It is proposed a theoretical framework of an effective online communication of CSR that integrates a set of indicators from three interlinked dimensions that are part of the dialogical capacity of organizations.

Abstract

Purpose

This study aims to develop a proprietary indicator to measure the digital presence of the institutions: the digital presence index.

Design/methodology/approach

This research delves into how nonprofit institutions, specifically business interest associations (BIAs), have developed their internet presence by applying essential digital marketing techniques. To this end, and using big data mining tools, this study analyzes the tracking by internet users of 102 BIAs, with their respective websites in 36 countries in Europe and the USA. In addition, the presence and activity of the institutions included in this study on social networks are considered.

Findings

This research serves as a basis for discussing the current gap between social reality and the digitalization of institutions. In this sense, conclusions are drawn on the importance of managerial profiles in decision-making on digitization and the necessary knowledge that, together with Web and social network managers, they must have to articulate the means and techniques that promote the internet presence of the organizations they manage.

Originality/value

Conclusions are drawn according to the geographical scope of the BIAs, and an argument is made about the difficulties of connection and loss of prominence of this type of institutions among their different target audiences, especially among the youngest and most digitized.

Abstract

Purpose

Despite the widespread use of excellence models as a self-assessment tool in the past two decades, little is known about the underlying logic behind the way that promoting organizations give weight to their criteria, and whether these scores align with business reality. This paper aims to analyze whether these scores coincide with the vision of managers and the real situation of business today.

Design/methodology/approach

This paper uses three different methods and two kinds of data to review the evolution of scores on criteria in excellence models since their creation and empirically analyses and compares the results with the vision of the managers.

Findings

The results show that the estimated weight of criteria in the European Foundation for Quality Management (EFQM) model (both directly perceived by managers and obtained with the statistical analysis) do not coincide with the value that the promoting organization has given to them, in its current version or in the previous versions.

Research limitations/implications

This paper is focused exclusively on industrial companies so one discussion point that can serve as a basis for future research is to study whether there is any difference in the distribution of points between industrial organizations and services, or between private and public organizations.

Practical implications

The results show that, depending of the methodology used to evaluate the weight of each element of the excellence model, these weights could be different and are different from those proposed by EFQM. Therefore, if managers want to use the EFQM model of excellence for self-evaluation purposes, they should define their own weights for each element, in accordance with their own company characteristics. Leadership, strategy, people, partnership & resources and processes could have more or less importance in promoting the success of a business, according to the specific situation of each company.

Originality/value

This study has been made using three different methods and two kinds of data.

Abstract

Purpose

This study aims to present diverse proposals for the measurement of tourism destination competitiveness that serve as alternatives to the travel and tourism competitiveness index (TTCI).

Design/methodology/approach

The proposal includes principal component analysis, the DP2-distance method, goal programming, data envelopment analysis and the Borda count. The study evaluates 17 destinations from Central America and the Caribbean.

Findings

These include the feasibility that the methodologies provide reliable competitiveness rankings and the possibility of using less information due to the strength of the statistical methodologies. International tourist arrivals, income from international tourism and travel and tourism contribution to the gross domestic product could be used as approximations of tourism destination competitiveness.

Research limitations/implications

The main limitation is the absence of major destinations from the region that constitutes fierce competitors.

Practical implications

New aggregation methods can build composite indicators for competitiveness measurement and their presentation in a more comprehensible way.

Social implications

The results serve as an alternative for countries that have yet to be considered in international tourism competitiveness comparisons.

Originality/value

A better explanatory power of the proposed index is given, thanks to their decomposition capacity and the reduction of the limitations of the original TTCI. Moreover, the proposals facilitate the inclusion of external information or the execution of a completely objective methodology.

目的

本研究旨在为衡量旅游目的地竞争力提出多样化的建议, 并作为旅行和旅游竞争力指数的替代方案。

设计/方法/方法

该提案包括主成分分析、DP2 距离方法、目标规划、数据包络分析和 Borda 计数。 该研究评估了中美洲和加勒比地区的 17 个目的地。

调查结果

结果包括这些方法提供可靠的竞争力排名的可行性, 以及由于统计方法的优势而使用较少信息的可能性。 国际旅游人数、国际旅游收入以及旅行和旅游对 GDP 的贡献可以用作旅游目的地竞争力的近似值。

研究局限/影响

主要局限是该地区没有竞争激烈的主要目的地。

实际意义

新的聚合方法可以为竞争力测量建立综合指标, 并以更易于理解的方式呈现。

社会影响

结果可作为国际旅游竞争力比较中, 衡量尚未考虑国家的替代方案。

原创性/价值

由于其分解能力和原始 TTCI 限制的减少, 所提出的指数具有更好的解释力。 此外, 这些建议有助于纳入外部信息及执行完全客观的方法。

Propósito

El presente estudio busca presentar diversas metodologías para medir la competitividad de los destinos turísticos, de modo que sirvan como alternativa al Índice de Competitividad de Viajes y Turismo.

Diseño/metodología/enfoque

La propuesta incluye Análisis de Componentes Principales, el método de distancia DP2, Programación por Metas, Análisis Envolvente de Datos y el Recuento de Borda. Se analizan 17 destinos de Centro América y el Caribe.

Hallazgos

Estos incluyen la validez de las metodologías para obtener rankings de competitividad fiables y la posibilidad de emplear menor cantidad de información, dadas las fortalezas de los procedimientos estadísticos propuestos. Las Llegadas de Turistas Internacionales, los Ingresos por Turismo Internacional, y la Contribución del Turismo al PIB podrían ser buenas aproximaciones para medir competitividad turística

Limitaciones/implicaciones

La principal limitación es la ausencia de destinos importantes de la región, que se consideran importantes competidores.

Implicaciones prácticas

Novedosos procedimientos de agregación para crear indicadores sintéticos para medir la competitividad turística y su presentación de un modo más comprensible.

Implicaciones sociales

Los resultados sirven como alternativa para otros destinos que aún no han sido considerados en comparaciones internacionales de competitividad turística.

Originalidad

Un mejor poder explicativo de los índices propuestos, gracias a su capacidad de descomposición, y la reducción de las limitaciones del índice del WEF. Además, las propuestas facilitan la inclusión de información externa o la ejecución de un método completamente objetivo.

Abstract

We present a critical literature review debating Brazilian research on social and environmental accounting (SEA). The aim of this study is to understand the role of politics in the construction of hegemonies in SEA research in Brazil. In particular, we examine the role of hegemony in relation to the co-option of SEA literature and sustainability in the Brazilian context by the logic of development for economic growth in emerging economies. The methodological approach adopts a post-structural perspective that reflects Laclau and Mouffe’s discourse theory. The study employs a hermeneutical, rhetorical approach to understand and classify 352 Brazilian research articles on SEA. We employ Brown and Fraser’s (2006) categorizations of SEA literature to help in our analysis: the business case, the stakeholder–accountability approach, and the critical case. We argue that the business case is prominent in Brazilian studies. Second-stage analysis suggests that the major themes under discussion include measurement, consulting, and descriptive approach. We argue that these themes illustrate the degree of influence of the hegemonic politics relevant to emerging economics, as these themes predominantly concern economic growth and a capitalist context. This paper discusses trends and practices in the Brazilian literature on SEA and argues that the focus means that SEA avoids critical debates of the role of capitalist logics in an emerging economy concerning sustainability. We urge the Brazilian academy to understand the implications of its reifying agenda and engage, counter-hegemonically, in a social and political agenda beyond the hegemonic support of a particular set of capitalist interests.
