This paper aims to define the class of fragment constructive heuristics used to compute feasible solutions for the traveling salesman problem (TSP) into edge-greedy and vertex-greedy subclasses. As these subclasses of heuristics can create subtours, two known methodologies for subtour elimination on symmetric instances are reviewed and are expanded to cover asymmetric problem instances. This paper introduces a third novel subtour elimination methodology, the greedy tracker (GT), and compares it to both known methodologies.

Computational results for all three subtour elimination methodologies are generated across 17 symmetric instances ranging in size from 29 vertices to 5,934 vertices, as well as 9 asymmetric instances ranging in size from 17 to 443 vertices.

The results demonstrate the GT is the fastest method for preventing subtours for instances below 400 vertices. Additionally, a distinction between fragment constructive heuristics and the subtour elimination methodology used to ensure the feasibility of resulting solutions enables the introduction of a new vertex-greedy fragment heuristic called ordered greedy.

This research has two main contributions: first, it introduces a novel subtour elimination methodology. Second, the research introduces the concept of ordered lists which remaps the TSP into a new space with promising initial computational results.

Project management (PM) is a diverse discipline which covers the study of management practices. Different research approaches have been used in the study of PM but not much emphasis has been given to the constructive approach which is implicitly applied in most cases through managerial constructions. The purpose of this paper is to support the application of the constructive research approach to the construction PM discipline. It is also aimed at showing the rigour of the constructive research approach that satisfies the requirements of applied studies research.

The study is carried out via extensive literature review and a demonstrative example of the development of the Specialist Task Organisation procurement approach through the six stages of the constructive research approach.

The paper shows the applicability of the constructive research approach to construction and PM. The paper also highlights some criticisms that the constructive approach has not been firmly rooted in PM research and suggests some solutions.

The constructive research approach is applicable to the PM discipline because most research in this field is applied and practical. The paper specifically scrutinises and promotes the constructive research approach.

The paper will provide an additional research tool in the PM discipline that produces innovative solutions which are grounded by valid research instruments. The impact of this paper will increase the popularity of this research methodology, generate and stimulate a debate to further explore its application and the development in the PM discipline.

Despite its volume, the academic research on the impact of electronic word of mouth (eWOM) on tourism and hospitality consumer behaviour is fragmented and largely limited to investigating a small scope of its impact. The purpose of this paper is to bridge this gap by synthesising the existing literature, providing a conceptual framework for the various dimensions of this impact.

This paper is based on the meta-synthesis and a critical conceptual analysis of relevant academic literature identified using a keyword search of papers via the Web of Science and Scopus databases, followed by a snowballing process comprising tracking the citations to the resources referred to in the identified papers.

This conceptual analysis illustrates how the full spectrum of the impact of eWOM on tourist behaviour spans well beyond the limited scope traditionally focussed on by tourism and hospitality researchers. This scope, encompassing multiple cognitive, normative and affective dimensions, is illustrated in an evidence-based conceptual framework proposed in this paper, providing a systematic tool to identify the less-studied aspects of this important phenomenon.

This paper synthesises the large and fragmented body of literature on eWOM and proposes a novel conceptual framework, illustrating the vast scope of the various cognitive, affective and normative mechanisms through which eWOM affects consumers’ choice of tourism and hospitality products. Furthermore, this paper provides a synthesis of the state-of-the-art of research in this field, highlights the existing gaps and provides researchers with a systematic tool to identify pathways towards breaking the status-quo in progressing beyond the current boundaries of academic research in this field.

El Boca a Boca Electrónico en el Comportamiento del Consumidor Turístico y Hotelero: Estado del Arte

A pesar del gran volumen de investigación académica sobre el impacto de eWOM en el comportamiento del consumidor turístico y hotelero, esta se encuentra fragmentada y en gran medida se limita a investigar un pequeño alcance de su impacto. El propósito de este artículo, es cerrar esta brecha sintetizando la literatura existente y proporcionando un marco conceptual para las diversas dimensiones de este impacto.

Este documento se basa en un análisis metasíntesis crítico y conceptual de la literatura relevante académica identificada, mediante una búsqueda de artículos por palabras claves a través de las bases de datos de Web of Science y Scopus, seguido de un proceso de “bola de nieve” que comprende el seguimiento de las citas de los recursos mencionados en los artículos identificados.

Este análisis conceptual, ilustra cómo el espectro total del impacto de eWOM en el comportamiento turístico se extiende mucho más allá del limitado alcance que tradicionalmente han realizado investigadores del turismo y hoteles. Este nuevo alcance, que abarca múltiples dimensiones cognitivas, normativas y afectivas, se ilustra en un marco conceptual basado en la evidencia propuesta en este documento, que proporciona una herramienta sistemática para identificar los aspectos menos estudiados de este importante fenómeno.

Este documento sintetiza la gran cantidad de literatura fragmentada sobre eWOM y propone un marco conceptual novedoso, que ilustra el amplio alcance de los diversos mecanismos cognitivos, afectivos y normativos a través de los cuales eWOM afecta la elección de los consumidores de productos turísticos y hoteleros. Además, este documento proporciona una síntesis del estado de la investigación en este campo, destaca las brechas existentes y brinda a los investigadores una herramienta sistemática para identificar vías para romper el statu quo en el progreso más allá de los límites académicos actuales en este campo.

Contemporary globalized societies face important environmental and social problems that require urgent action and citizen engagement. Active learning in contemporary societies is being reemphasized in order to prepare active learners, capable of critical thinking and innovative problem solving and able to become responsible citizens. Environmental Education (EE) and its descendant Education for Sustainability (EFS), or Education for Sustainable Development (ESD), have been a very important first effort for introducing active learning in contemporary education at all educational levels. They constitute an important variant of active learning. EE and EFS by definition propose and adopt active learning and experiential methods, as they seek to prepare people that will work for a healthy environment and better societies. And this is where the difference lies between EE/EFS and the generic active-learning approaches. EE or EFS are committed active-learning approaches; they have an explicit goal to work for social and environmental change.

The transition from learners to active learners is addressed by active learning, which however assumes that active learners will also become responsible and active citizens. EE and EFS have however demonstrated that this is not an obvious development. Education should be clear about its purpose – individual change, empowerment, integration, or social transformation – and pedagogical methods and tools should be selected appropriately.

This chapter first discusses the main characteristics of EE/EFS. Then, it explores what facilitates the transition from active learners to active citizens, based on lessons from EE and EFS. Finally, it reflects on the implications of these lessons for Higher Education and, as a result, a new vision for Higher Education and a brief guide for educators and Higher Educational managers are proposed.

The purpose of this study is to develop an immune genetic algorithm (IGA) to solve the simple assembly line balancing problem of type 1 (SALBP-1). The objective is to minimize the number of workstations and workstation load for a given cycle time of the assembly line.

This paper develops a new solution method for SALBP-1, and a user-defined function named ψ(·) is proposed to convert all the individuals to satisfy the precedence relationships during the operation of IGA.

Computational experiments suggest that the proposed method is efficient.

An IGA is proposed to solve the SALBP-1 for the first time.

The city of Fortaleza, capital of the state of Ceará in the north-east of Brazil, presents a paradox as a present-day tourist destination, while also marked by features and processes characteristic of cities in the Global South, such as high levels of social inequality with fragmented urban margins and vulnerabilities. This research problematizes the idea of “historical ruins” proposed by Walter Benjamin as a viable way to understand how the organization process of today's city margins can be “denaturalized” by the past. The objective of this research is to assess how the urban margins of the city were organized as a history of resistance.

In theoretical terms, this research links critical urban studies with critical approaches to organizational history (COH) based on Walter Benjamin's philosophical concepts of “ruins” and “progress”. The historical and archival methodology, consisting of 193 documents, suggests the existence of a philosophical–historical nexus that helps explain the spatial fragmentation of the city, and especially the urban margins in the western region of Fortaleza.

The Benjaminian notion of “historical ruins” has been exemplified by the Brazilian government practices confining migrants fleeing drought in internment camps on the margins of the city of Fortaleza in three waves beginning in 1877, 1915 and 1932 respectively. The effects of such confinement policies put into practice in the name of “progress” influenced the organization of large urban spaces on the city's margins, whereas on the other hand, the analyses advanced in this research reflect on alternatives to re-frame the history of the organization of the margins of Fortaleza through a set of practices of resistance.

Based on the concept of “denaturalization”, and through re-activation of the memory of a circumstantial past, the gaze of the “ruins”, as represented by the belief in “progress” addressed in official reports of government confinement policies, spaces of resistance have emerged where new possibilities for the future of the city can be imagined.

The problem of long delay and waiting time in Disabled Facilities Grants (DFG) housing adaptation has been ongoing for years. This study aimed at constructing an innovative smart solution to streamline the housing adaptation process to prevent lengthy delays for disabled and elderly people.

The Adapt-ABLE approach is suggested based on a constructive research approach, where extensive theoretical development of the Adapt-ABLE concept is developed. It consists of four integrated platforms that undergo theoretical and analogical development and validations through applicable theories, a workshop, four brainstorming sessions and a focus group.

The proposed Adapt-ABLE approach utilises process optimisation techniques through an IT system for streamlining the process. The merits of the semi-automated system include the development of a preventive measure that allows measurement of suitability index of homes for the occupants, indicative assessment that shorten the application duration, procurement and contracting platform that utilises principles based on framework agreement and call-off contract, and a platform that standardised performance management for continuous improvement.

The Adapt-ABLE solution will cut the application journey of non-qualified applicants and suggest where help can be sought. The qualified applicants' application journey will also be shortened through an online indicative assessment regime and early online resources (means) testing. Overall, the proposed system reduces the waiting time, and timely delivery improves the applicant's quality of life by living independently. It will potentially save the NHS billions of pounds used to replace hips and residential care costs due to lengthy delays in the housing adaptations process.

Theorists often point to social theory's normativity, but Gouldner's later works provide the most explicit, comprehensive treatment of it as post-traditional normative discourse – a practice distinct from sociology and sociological theory, yet linked historically and analytically to them. His argument about the need for a discourse space to debate social science's normative directions and to strengthen its connections to civil society is relevant today. Because Gouldner's approach has gaps and is somewhat fragmented I will reconstruct his argument about social theory per se. Although I point to problems that derive from his incomplete pragmatic turn, his approach offers an excellent departure point for discussing the meaning of social theory.

Where do all the management theories and fads come from? Why are they so different and constantly changing. This paper develops a comprehensive and dynamic cognitive formwork from an understanding of the formulations of Aquinas, Lonergan, Jung, Weber and the Enneagram. The synthesis is new and goes beyond each of the sources to present a more systematic and useable JEWAL synthesis formwork. First, the neo‐platonic hierarchical structure of triadic unity is identified as a particularly pertinent and effective differentiation of reality. Second, whereas the neo‐platonists developed their hierarchical construction of reality from a meta‐physical viewpoint as emanations from the ultimate unity, later philosophers explained the differentiation of consciousness principally by working in the reverse direction. Third, the paper explains the process of learning in terms of the cognitive procession through the layered levels of differentiated consciousness. Fourth, an explanation follows as to how this cognitive formwork can be used to explain a character typology based on the differentiation of consciousness – one that finds expression in a typology commonly known as the Enneagram. Fifth, the JEWAL synthesis formwork is presented as a comprehensive framework in which to understand human governance and social action. More broadly, the paper discusses the significance for the social sciences of achieving such a synthesis of ideas within this new formwork – a synthesis between the Western developed philosophy, which runs through the work of Aquinas, Lonergan, Weber and Jung, and the Eastern physio‐psychological wisdom encapsulated in the Enneagram typology. In conclusion, the paper attempts to bring it all together in an answer to the questions underpinning the paper; namely, what does it mean to know and how do we make sense of those voices that speak out of that knowing.

This paper aims to examine the significance of information communication technology (ICT) for Balkan labour. Drawing on the heuristic of “distributed discourse”, this paper aims to explore virtual forms of communication and interaction. The paper aims to examine the privileged role of ICT in the: formation of autonomous trade union structures and channels of communication; evasion of the territorial structures of the nation‐state and the construction of virtual communities of international labour solidarity; and authoritative transmission of models of industrial relations practice and of capitalist modernity in virtual space.

The authors conducted in‐depth interviews, followed up by further discussions, with officials and researchers from unions in the Balkan region. IR academics in Serbia and Montenegro were also consulted, as were union web sites and those of the Confederation of Independent Trade Unions of Serbia, Association of Free and Independent Trade Unions of Serbia. The purpose of the dialogue was to build an empirically grounded framework for understanding the limits and possibilities presented by the new distributed communications technologies of the internet for labour in the era of globalisation. This article provides qualitative data to allow reflection on the possibilities inherent in ICT for the reinvigoration of trade unionism and labour mobilisation in this era of rampant neoliberalism, particularly in the area of trade union democratisation and accountability.

The article finds that key figures within the Balkan labour movement are conversant with the potential of ICTs. It is also apparent that the construction of cyber‐unionism at the official level is subject to the authoritative force of neo‐liberal imperial governance. However, this is a regime of policing that is indexed and auditable through the very distributed communication technologies which can affect forms of meta‐governance beyond the control of institutions.

The findings, based on the interrogation of qualitative data are provisional hypotheses and an invitation to further research on the space‐time dimensions of trade unionism in the age of globalisation.

This paper highlights the situated character of ICT utilisation. While ICTs can be implicated in the reproduction of extant organisational forms and politics, this article provides the international labour movement with a viewpoint from which to build ICT strategies and appropriate organisational structures that recognise the limitations of centralised representation and control.

This paper represents fresh and contemporary data on the use of the internet by Balkan labour. By interrogating the qualitative data an invitation to further research on the space‐time dimensions of trade unionism in the age of globalisation is presented.
