Abstract

Fuzzy preference relations are considered and the concept of “fuzzy acyclity” is defined in order to measure their rationality. Such a concept is applied to study the properties of social welfare function in a fuzzy environment. In particular, the existence of non‐irrational aggregation rules is assured, in such a way that they can be used as a group decision aid.

Abstract

Food insecurity in the Latin American region has become a complex problem that significantly impacts people's physical and mental well-being. The factors causing food insecurity are varied, ranging from social, political, and economic causes. Ensuring access to food is not a task with limited responsibilities; on the contrary, both public and private institutions must contribute to creating sustainable and innovative solutions. In general, it is necessary to ensure that the food system flows correctly, ensuring the availability of balanced and nutritious food for the diet of the inhabitants of a given nation. Alternative solutions apart from the government's help include sustainable cultivation, finger millet, and close cooperation with the farmers from the agriculture sector. The present research aims to consolidate theoretical information on the Latin American situation and seek the leading solutions of the parties involved.

Abstract

Purpose

This paper aims to study the suitability of a selection of 3D printing liquid photopolymer resins for their application in the cultural heritage context.

Design/methodology/approach

The main concerns regarding the conservation and restoration of cultural assets are the chemical composition and long-term behavior of the new materials that will be in contact with the original object. Because of this, four different LED curing resins were exposed to an accelerated aging procedure and tested to identify the materials which demonstrated a better result. Some specific properties of the material (color, glossiness, pH and volatile organic compound emissions) were measured before and after the exposure.

Findings

Some of the properties measured reported good results demonstrating a decent stability against the selected aging conditions. The main changes were produced in the colorimetric aspect, probably indicating other chemical reactions in the material. Likewise, a case study could be also executed to demonstrate the usefulness of these materials in the cultural field.

Research limitations/implications

It is necessary to study in more detail the long-lasting behavior of the materials employed with these technologies. Further analysis should be carried out highlighting the chemical composition and degradation process of the materials proposed.

Originality/value

This paper contributes to the introduction of curing 3D printing resins in the restoration methodologies of cultural assets. For this, the study of a selection of properties represents the first stage to suggest or reject their use.

Abstract

Purpose

This paper evaluates consumers' responses to claims regarding fruit sustainability. The authors compared the effects of this factor on consumers' moral satisfaction and purchase intention with respect to 12 sustainability claims.

Design/methodology/approach

A mixed-model experiment was conducted with seven fruits (i.e. guava, pineapple, red apple, green apple, red grape, green grape and avocado) to evaluate the effects of the 12 sustainability claims on purchase intention through moral satisfaction, relative to a control condition.

Findings

The results show that claims of supporting local farmers are those that move consumers the most. Claims regarding local farmers' production positively affect moral satisfaction and purchase intention.

Practical implications

This paper takes a consumer behavior approach to sustainability, enabling organizations to consider consumer behavior outcomes that could affect their strategic investments and commitment to social responsibility.

Originality/value

Food-related studies have not produced consistent results with respect to the relevance that sustainability claims have for consumers. This study differs from previous studies, as it focuses on fruit, a product that is important for social and environmental sustainability issues. This study demonstrates that, in the case of fruit, sustainability arguments are meaningful to young consumers through the mediating effect of moral satisfaction. Thus, the effect of claims is predicted by the meaning these arguments have for the consumer.

Propósito

Este artículo evalúa las respuestas de los consumidores a los argumentos de sostenibilidad en una fruta. Se comparan los efectos de este factor en la satisfacción moral y la intención de compra de los consumidores con respecto a 12 argumentos de sostenibilidad.

Diseño/metodología/enfoque

Se realizó un experimento de modelo mixto con siete frutas (guayaba, piña, manzana roja, manzana verde, uva roja, uva verde y aguacate) para evaluar los efectos de los 12 argumentos de sostenibilidad sobre la intención de compra a través de la satisfacción moral, en relación con una condición de control.

Hallazgos

Los resultados muestran que las afirmaciones de apoyo a los agricultores locales son las que más influyen en los consumidores. Las afirmaciones relativas a la producción de los agricultores locales afectan positivamente a la satisfacción moral y a la intención de compra.

Implicaciones prácticas

Este trabajo adopta un enfoque de la sostenibilidad basado en el comportamiento del consumidor, lo que permite a las organizaciones considerar los resultados del comportamiento del consumidor que podrían afectar a sus inversiones estratégicas y a su compromiso con la responsabilidad social.

Originalidad

Los estudios relacionados con la alimentación no han arrojado resultados consistentes respecto a la relevancia que los argumentos de sostenibilidad tienen para los consumidores. Este estudio difiere de los anteriores, ya que se centra en la fruta, un producto importante por cuestiones de sostenibilidad social y medioambiental. Este estudio demuestra que, en el caso de la fruta, los argumentos de sostenibilidad son significativas para los consumidores jóvenes a través del efecto mediador de la satisfacción moral. Así, el efecto de los argumentos se predice por el significado que estos tienen para el consumidor.

Abstract

Purpose

Negative rumors damage the destination’s image and tourist experience. This study aims to compare how rumor correction sources (government vs business vs tourist) affect user online citizenship behavior (UOCB).

Design/methodology/approach

Based on the stimuli-organism-response framework, a hypothetical model was established from rumor correction to UOCB. Three scenario experiments (more than 1,000 valid samples) were designed. Study 1 illustrated the effects of different rumor corrections, Study 2 was designed to verify the mediating effects of sympathy and perceived information authenticity (PIA) and the robustness of results was demonstrated in Study 3.

Findings

Government correction elicited the highest sympathy and PIA. Business correction was less than tourist correction in arousing sympathy but better than tourist correction in enhancing PIA. Sympathy and PIA had a mediating effect on the relationship between rumor correction and UOCB.

Practical implications

This study helps to identify the different advantages of rumor correctors and provides insights to prevent the deterioration of negative tourism rumors or even reverse these crises.

Originality/value

This study innovates research perspective of negative tourism rumor governance, expands the understanding of the effect and process of rumor correction and enriches the research content of tourism crisis communication.

目的

负面谣言破坏目的地形象和游客体验。本研究比较谣言纠正来源(政府、企业、游客)对用户在线公民行为的影响。

设计/方法/途径

基于刺激-有机体-反应框架, 搭建谣言纠正到用户在线公民行为的假设模型, 并设计3个情境实验(超过1000个有效样本)。实验1验证不同谣言纠正来源的纠正效果, 实验2证明同情和感知信息真实性的中介作用, 实验3测试实验结果的稳健性。

研究发现

政府纠正引发最高的同情和感知信息真实性。企业纠正在唤起同情时不足于游客纠正, 但在增强感知信息真实性时优于旅游纠正。同情和感知信息真实性在谣言纠正与用户在线公民行为之间发挥中介作用。

实践意义

有助于识别各个谣言纠正主体的不同优势, 为防止旅游负面谣言恶化甚至转危为安提供见解。

原创性/价值

为旅游负面谣言治理提供新的研究视角, 拓展了对谣言纠正效果和过程的认识, 丰富了旅游危机沟通的研究内容。

Propósito

Los rumores negativos dañan la imagen del destino y la experiencia del turista. Este estudio compara cómo afectan las fuentes de corrección de rumores (gobierno vs empresas vs turista) en el comportamiento cívico online de los usuarios (CCOU).

Diseño/metodología/enfoque

Sobre la base del marco estímulo-organismo-respuesta, se estableció un modelo hipotético desde la corrección de rumores hasta el CCOU. Se diseñaron tres escenarios experimentales (más de 1.000 muestras válidas). El Estudio 1 ilustró los efectos de las diferentes correcciones de rumores, el Estudio 2 se diseñó para verificar los efectos mediadores de la simpatía y la autenticidad percibida de la información (API), y la solidez de los resultados se demostró en el Estudio 3.

Hallazgos

La corrección del gobierno obtuvo la mayor simpatía y API. La corrección de la empresa despertó menos simpatía que la corrección del turista, pero fue mejor para generar API. La simpatía y la API tuvieron un efecto mediador en la relación entre la corrección del rumor y el CCOU.

Implicaciones practices

Ayuda a identificar las diferentes ventajas de los correctores de rumores y proporciona información para prevenir el deterioro de los rumores turísticos negativos o incluso revertir estas crisis.

Originalidad/valor

Proporciona una nueva perspectiva de investigación de la gobernanza del rumor turístico negativo, amplía la comprensión del efecto y el proceso de corrección de rumores y enriquece el contenido de la investigación de la comunicación de crisis turísticas.

Abstract

Purpose

Even though the implementation of lean in health care environments is relatively recent, it has been receiving a lot of attention in recent years. Partly because of the fact that it is a recent field of practise and research and partly because the number of works developed in this field has grown rapidly, it is important to frequently update the perspectives on this field of investigation. Thus, this study aims to review the implementation of lean tools and techniques applied to hospital organizational areas in a five-year period, between 2014 and 2018, complementing some of the most relevant reviews already published. The most important criteria such as tools, methods and principles, hospital areas intervened, improvements and difficulties were assessed and quantified.

Design/methodology/approach

As starting point for this systematic literature review (SLR), a set of selected pre-existing review publications was used to support the current study and as the ground base for the expansion of the studies about lean health care. The current study contemplated 114 articles from a five-year period between 2014 and 2018. A subset of 58 of these articles was critically assessed to understand the application of lean tools and methods in different hospital areas.

Findings

The thorough analysis of selected articles show a lack of works in continuous improvement approaches when compared to the application of production organization methods, visual management and diagnosing and problem-solving tools. The reported improvement results demonstrate alignment with the principles and foundations of lean philosophy, but such results are presented in isolated initiatives and without robust evidence of long-term maintenance. Moreover, this study shows an evolution in the number of articles referring to lean implementation in hospital areas, but in its great majority, such articles report isolated implementations in different areas, not spreading those for the global organization. Thus, some of the main recommendations are the need to implement studies on complete flows of patients, drugs and materials, instead of isolated initiatives and strive to promote the cultural change of hospitals through structural changes, following new visions and strategic objectives, supported by real models of continuous structural and sustained improvement.

Originality/value

The current study develops a new perspective of the articles published under the thematic of lean health care, published in a recent period of five years, which are not completely covered by other works. Additionally, it explicitly applied, in an innovative way, an approach that used a set of previous reviews as the starting point for this SLR. In this way, it integrates approaches and categories from different SLRs, creating a framework of analysis that can be used by future researchers. Finally, it shows the most recent implementations of lean health care, exposing the current trends, improvements and also the main gaps.

Abstract

Purpose

The identification (listing) and classification (grading) of urban heritage buildings for conservation is a challenging task for urban planners and conservation architects. Most of the world's cities depend on the expert-based evaluation method (EBEM) for listing and grading heritage buildings. The Panaji city in India provided a unique opportunity to assess the performance of the EBEM as two independent agencies carried out the heritage listing and grading process. Considering the case of Panaji, this research aims to measure the performance of EBEM used for listing and grading heritage buildings and identify the issues associated with the existing methodology.

Design/methodology/approach

This research presents a comparative analysis of the building listed and graded by the two agencies. The buildings that both agencies graded were identified and analysed using a confusion matrix. The grading classification was tested for accuracy, precision, sensitivity and F-score.

Findings

The result shows a low accuracy and F-score, which reflects the level of buildings misclassified. The misclassification is the product of the lack of standardisation of methodology and the subjectivity level involved in the EBEM.

Originality/value

Heritage listing and grading is a time-consuming process, and no city has the time and resource to conduct studies to check the accuracy. The cities in India and across the world, which follow a similar EBEM process, should consider this study's finding and revisit their methodology and develop a more reliable methodology for listing and grading heritage buildings.

Abstract

Purpose

The present study analyzes differences in self-perceived employability (SPE) among Spanish university and vocational education and training (VET) students. It also aims to determine whether factors such as gender, work experience and perceptions of the precariousness of the job market have a differential effect on SPE in accordance with the training pathway chosen by emerging adults.

Design/methodology/approach

A total of 1,715 university students (64.7% women) and 488 VET students (37.1% women) aged between 18 and 29 years completed a self-administered questionnaire that included measures of perceived employability and precarious employment.

Findings

The results indicate higher SPE among VET students than among their university counterparts. Female university students scored lower also than their male colleagues, an effect that was not observed among VET students. Prior work experience improved internal SPE among students on both training pathways. However, among university students, work experience and precarious employment reduced external SPE, an affect that was not observed among VET students.

Practical implications

The analysis of differences in SPE between university and VET students highlights the importance of an educational curriculum that includes practical competences for enhancing employability. The results also reflect the negative consequences of precarious employment on feelings of employability during this life stage, particularly among those studying at university.

Originality/value

This is one of the first studies to analyze the perceived employability of emerging adults on two different training pathways in Spain.

Abstract

Purpose

The primary aim of the current study is to validate the theoretical model presented by Demir (2021a, b, c) via empirical evidence. In this respect, the study intends to offer a holistic pathway for obtaining both external and internal advantages from the implementation of ISO 9001, with a particular emphasis on developing countries.

Design/methodology/approach

The research utilized an empirical methodology to investigate the research objective. Data were collected from various sources, including employees and managers of the various companies. In this context, a model was developed, and 170 data points were collected from businesses in the Kurdistan region of Iraq in order to test the hypotheses in this model.

Findings

After the collected data passed the reliability and validity test, the hypotheses designed were tested by applying the partial least squares method. When the results were examined, it was observed that organizational culture and organizational learning variables were the two key antecedents that these factors would emerge after applying ISO 9001 practices with discipline for a certain period of time and that organizational benefits could be obtained only as a result of them. Detailed results and suggestions were given to managers and theorists as a result of the analysis.

Originality/value

This study contributes to the literature as an empirical application of the theoretical work written by Demir in 2021. Demir's work, which produced a theoretical concept based on many empirical and theoretical studies done before, still needs much more empirical work in developing countries.
