Abstract

Purpose

This study aims to propose a new scheme for designing a high-sensitivity optical biosensor. For this, two agents have been considered: reflection-type micro-resonators, which filter the noise of the pump, and coupled-ring reflectors (CRRs), which are coupled to partial reflecting elements in the bus waveguide to create Fano-resonance. These two agents improve the sensor sensitivity and have low-power optical switching/modulation.

Design/methodology/approach

The proposed model is based on the coupling of the CRRs with the Fabry–Pérot cavity. The slope of the Fano-resonance line shape and consequently the sensitivity of the proposed CRRs are higher than those of conventional microring resonators.

Findings

The proposed scheme has many characteristics: CRRs have been used to create a higher slope of the Fano-resonance line shape; the sensitivity of the sensor shows improvement on the basis of reflection-type micro-resonators and by the removal of the pump noise; the designed sensor has low-power optical switching/modulation; and the modeling and designing of a novel high-sensitivity resonator is based on coupling the CRRs with the Fabry–Pérot cavity.

Originality/value

This study has proposed a new scheme for designing a high-sensitivity optical biosensor. This method is based on the improvement of the sensitivity by two agents: reflection-type micro-resonators, which filter the noise of the pump, and coupled-ring reflectors, which are coupled to partial reflecting elements in the bus waveguide to create Fano-resonance.

Abstract

Purpose

The purpose of this paper is to investigate the impact of internal strategic alignment (ISA) on business performance. A model is developed in which internal alignment is explained by the covariance between vertical and horizontal alignment. The perspective of business strategy implementation is adopted in order to support the theoretical relationship between the variables.

Design/methodology/approach

The partial least squares method, a structural equation modeling technique, is applied to estimate the model.

Findings

The results provide empirical validation for the model and confirm the positive relationship between internal alignment and business performance.

Practical implications

The ISA model is an essential aid for executives when implementing strategies and the validated research instrument can be applied for firms as a diagnosis of internal alignment in the organization.

Originality/value

The research contributed to meet the need for studies involving strategy implementation, as its formulation has already been emphasized, as well as to the need for models of strategic internal alignment that include activities relevant to the successful execution of the strategy, and to the need for alignment studies based on a holistic perspective.

Objetivo

O estudo foi conduzido com o objetivo de avaliar o impacto do alinhamento estratégico interno sobre o desempenho do negócio. Foi desenvolvido um modelo em que o alinhamento interno é explicado pela covariância entre o alinhamento vertical e o alinhamento horizontal. É adotada a perspectiva da implementação da estratégia de negócios para apoiar a relação teórica entre as variáveis.

Diseño/metodología/enfoque

Os dados foram processados e validados por meio da técnica de Modelagem de Equações Estruturais com estimação pelo método Partial Least Squares (PLS).

Resultados

Os resultados dão validação ao modelo e confirmam a relação positiva entre o alinhamento estratégico interno e o desempenho organizacional.

Implicações práticas

O Modelo de Alinhamento Estratégico Interno define um conjunto de ações que podem servir de guia para os executivos quando da implementação da estratégia. Os instrumentos validados podem ser aplicados pelas organizações para realizar um diagnóstico do alinhamento interno.

Originalidad/valor

Esta pesquisa traz contribuições quanto à necessidade de estudos envolvendo a implementação da estratégia, uma vez que ênfase tem sido dada à formulação; quanto à escassez de modelos de alinhamento estratégico interno que integrem atividades relevantes para a execução bem sucedida da estratégia e à necessidade de estudos de alinhamento empregando a perspectiva holística.

Abstract

Purpose

The purpose of this paper is to investigate the issue of efficiency in the Brazilian motor carrier industry, which has undergone significant transformations since the economy deregulation in the mid-1990s. The main research objective is to determine whether or not different types of cargoes and geographic regions serviced significantly impact trucking managerial efficiency levels.

Design/methodology/approach

Research objectives are accomplished by applying a two-stage data envelopment analysis model with bootstrapped estimates. Based on an unbalanced panel model, secondary data from the annual study published by Transporte Moderno (years 2002-2010) were collected and analyzed.

Findings

Results support anecdotal evidence regarding a heterogeneous impact of cargo mix and route mix on efficiency levels.

Research limitations/implications

A major limitation of this work concerns the fact of working with secondary data instead of primary data, especially with respect to the set of inputs and outputs used in the analysis, which may not cover all aspects relevant to building an efficiency frontier. Despite this limitation, the study has made an important contribution in its use of panel data to demonstrate the impacts of different types of cargoes and geographic regions serviced on managerial efficiency levels in the trucking industry.

Practical implications

Managerial impacts in terms of mergers and acquisitions are addressed.

Originality/value

The contribution of this study is twofold. On the theoretical side, a valuable scale for the measurement of managerial efficiency was built and validated, representing an index toward the most productive cargo/route mix. On the other hand, the managerial implication of this possibility of measuring the efficiency levels is that motor carriers can use it as a basis for establishing future action plans.

Abstract

This chapter presents a theoretical reflection on the possible impact of politicians' positive Word of Mouth (pWOM) on the tourists' risk perception and destination image of Portugal in the context of the COVID-19 pandemic. The reflection is based on the collection of remarks or comments made by international politicians collected using Google as the search engine and subsequent manual textual content analysis. The results show five recurring themes in the politicians' pWOM: general praise, pandemic numbers, politician positioning, health care and population attitude. The discussion includes a reflection on the outputs of the channels used for the dissemination of the messages and the importance of the politicians' countries of origin to a market strategy that highlights Portugal as a tourism destination.

Abstract

Discusses the linguistic influences on an electronic publishing infrastructure in an environment with unstable linguistic standardization from the computational point of view. Essentially, in Serbia in the last half of the century (at least) publishing is based on the following facts: two alphabetic systems are regularly in use with the possibility to mix both alphabets in the same document; the various dialects are accepted as a part of a linguistic norm; orthography is unstable ‐ presently, several linguistic attitudes that have different views of the orthographic norm are under discussion; and, in Serbia, many minority languages are in use, which makes it difficult to provide efficient contact between different communities through electronic publishing. In this context, a systematic solution that responds to this complex situation has not been developed in the frame of traditional Serbian linguistics and lexicography in a way that enables the adequate incorporation of the new publishing technologies. Owing to these constraints, the direct application of electronic publishing tools frequently causes the degradation of the linguistic message. In such an environment, the promotion of electronic publishing therefore needs specific solutions. The paper discusses the general frame based on the specifically encoded system of electronic dictionaries that makes electronic texts independent of some of the mentioned constraints. The objective of such a frame is to enable the linguistic normalization of texts at the level of their internal representation, and to establish bridges for communicating with other language societies. Some aspects of electronic text representation that ensures its correct interpretation in different graphical systems and in different dialects are described. This also allows text indexing and retrieval using the same techniques that are available for languages not burdened with these problems.

Abstract

Purpose

Different from most academic publications about tourism in Brazil, this paper provides an overarching and comprehensive perspective. Analysing key developments, and focusing on the period 2000–2019, this paper also considers long-standing structural issues that hinder tourism development. Although this viewpoint paper deals with Brazil, very similar issues can be identified for many countries worldwide.

Design/methodology/approach

This viewpoint paper is a combination of reflections by leading Brazilian tourism academics; most are members of ABRATUR, the International Academy for the Development of Tourism Research in Brazil. This paper uses secondary data from the grey (e.g. government reports) and academic literature to support this opinion paper. The tourism-related topics covered in this paper include economics, policy and planning, marketing, transport, nature-based tourism, gastronomy, hospitality and education, amongst others.

Findings

Brazil has missed several unique opportunities to place it as a destination of international renown. Since the 1990s, efforts to support regional tourism development have achieved only moderate success as political instability, violence and corruption have impacted tourism. A lack of a coordinated approach between the various levels of government, a shortage of tourism data and a long-term supra-government marketing campaign, among other factors, have meant Brazil has missed several critical opportunities in the 2010s to establish itself as a leading tourism destination in the global market.

Originality/value

From leading tourism academic experts in Brazil, a unique opinion paper offers an overview of the critical development issues in 2000–2019. The paper presents matters that have hindered potential tourism contributions to the largest nation in South America. While these matters may be specific to Brazil, many of these challenges are not dissimilar to those in other emerging (democratic) nations. The authors offer several public policies and technical recommendations to scaffold tourism development towards the 2030 agenda.

设计/方法/途径

本篇观点论文是巴西前沿旅游学者们思考的集合, 其中大多数的学者是巴西旅游发展国际研究院ABRATUR的成员。这篇论文使用了诸如政府工作报告的二手数据和学术文献来支撑文章观点。其中涉及的与旅游相关的主题包括经济学, 政策和规划, 市场营销, 交通, 自然旅游, 烹饪学, 酒店, 教育等等。

目的

与巴西大多数旅游研究的出版物不同, 本文提供了一个重要且全面的视角。文章重点分析了从2000-2009年的旅游业主要发展状况, 同时考虑了阻碍旅游业发展的长期结构性问题。尽管此观点论文涉及巴西, 但在世界许多国家都可以发现非常相似的问题。

结果

巴西已经错失了作为国际知名旅游目的地的几个独特机会。二十世纪九十年代以来, 因为政治动荡, 暴力和腐败对旅游业的影响, 支持区域旅游业发展的努力仅仅取得了有限的成功。各级政府之间缺乏协调方式, 旅游数据短缺和长期的跨政府营销活动等因素, 已经意味着巴西在二十一世纪前十年已经错失了将自己在全球市场中确立为领先旅游目的地的几个重要机会。

创新/价值

这篇来源于一些巴西学术旅游届的领头羊的独特观点论文概述了从2000年到2019年巴西旅游业发展的关键问题。本文介绍了那些已经阻碍南美洲最大旅游国家潜在旅游业贡献的重要事项。尽管这些事项可能是巴西独有的, 但是其中许多问题与其他新兴的(民主的)国家也没有什么不同。我们提供了一些公共政策和技术建议, 以支持旅游业向2030年议程迈进。

Diseño/metodología/enfoque

Este artículo de opinión es una combinación de reflexiones de destacados académicos brasileños del turismo, la mayoría miembros de ABRATUR, la Academia Internacional para el Desarrollo de la Investigación en Turismo en Brasil. Se utilizan fuentes secundarias (por ejemplo, informes gubernamentales) y literatura académica para respaldar este artículo. Los temas relacionados con el turismo que se tratan en este documento incluyen economía, política y planificación, marketing, transporte, turismo basado en la naturaleza, gastronomía, hotelería, y educación, entre otros.

Propósito

A diferencia de la mayoría de las publicaciones académicas sobre el turismo en Brasil, este artículo ofrece una perspectiva global e integral. Al analizar los desarrollos clave y centrarse en 2000–2019, este documento también considera problemas estructurales de larga data que obstaculizan el desarrollo del turismo. Aunque este documento trata de Brasil, se pueden identificar problemas muy similares en muchos otros países del mundo.

Resultados

Brasil ha perdido varias oportunidades únicas para colocarse como un destino de renombre internacional. Los esfuerzos realizados desde la década de 1990 para apoyar el desarrollo del turismo regional solo han logrado un éxito moderado debido a que la inestabilidad política, la violencia y la corrupción han impactado al turismo. La falta de un enfoque coordinado entre los distintos niveles de gobierno, la escasez de datos turísticos, una campaña de marketing supra gubernamental a largo plazo, entre otros factores, han significado que Brasil haya perdido varias oportunidades críticas en la década de 2010 para establecerse como un destino turístico líder en el mercado global.

Originalidad/valor

Un artículo de opinión único de destacados expertos académicos en turismo en Brasil, que ofrece por primera vez una visión general de los problemas críticos del desarrollo desde la década del 2000. El documento presenta asuntos que han obstaculizado las posibles contribuciones del turismo a la nación más grande de América del Sur. Si bien estos asuntos pueden ser específicos de Brasil, muchos de estos desafíos no son diferentes a los de otras naciones (democráticas) emergentes. Ofrecemos diversas recomendaciones técnicas y de políticas públicas para impulsar el desarrollo turístico hacia la agenda 2030.
