Abstract

Purpose

Most digital libraries (DL) are now available online. They also provide the Z39.50 standard protocol which allows computer-based systems to effectively retrieve information stored in the DLs. The major difficulty lies in inconsistency between database schemas of multiple DLs. The purpose of this paper is to present a system known as Argumentation-based Digital Library Search (ADLSearch), which facilitates information retrieval across multiple DLs.

Design/methodology/approach

The proposed approach is based on argumentation theory for schema matching reconciliation from multiple schema matching algorithms. In addition, a distributed architecture is proposed for the ADLSearch system for information retrieval from multiple DLs.

Findings

Initial performance results are promising. First, schema matching can improve the retrieval performance on DLs, as compared to the baseline technique. Subsequently, argumentation-based retrieval can yield better matching accuracy and retrieval efficiency than individual schema matching algorithms.

Research limitations/implications

The work discussed in this paper has been implemented as a prototype supporting scholarly retrieval from about 800 DLs over the world. However, due to complexity of argumentation algorithm, the process of adding new DLs to the system cannot be performed in a real-time manner.

Originality/value

In this paper, an argumentation-based approach is proposed for reconciling the conflicts from multiple schema matching algorithms in the context of information retrieval from multiple DL. Moreover, the proposed approach can also be applied for similar applications which require automatic mapping from multiple database schemas.

Abstract

Unsustainable logging and illegal logging for domestic and international trade and trafficking continue to lead to deforestation. It is crucial that Sustainable Development Goal 15 ‘Sustainably manage forests, combat desertification, halt and reverse land degradation, halt biodiversity loss’ is achieved to maintain the livelihoods of people and protect the planet. This is the case in Vietnam as well, where many people, including indigenous groups, rely on the forest for their survival. Drawing on semistructured interviews in Vietnam and a literature review, we investigate how the abuse of forest policies leads to human insecurity. From this, we propose solutions to (1) end unsustainable harvesting and illegal logging (SDG 15.7), (2) integrate the value of forests (culturally and economically) into national and local planning, the development process and poverty elimination strategies (SDG 15.9) and (3) improve the use of forest protection funding provided by international donors.

Abstract

Purpose

A higher-order Reissner-Mindlin plate element method is presented based on the framework of assumed stress quasi-conforming method and Hellinger-Reissner variational principle. A novel six-node triangular plate element is proposed by utilizing this method for the static and free vibration analysis of Reissner-Mindlin plates.

Design/methodology/approach

First, the initial assumed stress field is derived by using the fundamental analytical solutions which satisfy all governing equations. Then the stress matrix is treated as the weighted function to weaken the strain-displacement equations after the strains are derived by using the constitutive equations. Finally, the arbitrary order Timoshenko beam function is adopted as the string-net functions along each side of the element for strain integration.

Findings

The proposed element can pass patch test and is free from shear locking and spurious zero energy modes. Numerical tests show that the element can give high-accurate solutions, good convergence and is a good competitor to other models.

Originality/value

This work gives new formulations to develop high-order Reissner-Mindlin plate element, and the new strategy exhibits advantages of both analytical and discrete methods.

The purpose of this paper is to use Twitter analysis to explore diner perceptions of four types of Asian restaurants (Chinese, Japanese, Korean and Thai).

Abstract

Purpose

The purpose of this paper is to use Twitter analysis to explore diner perceptions of four types of Asian restaurants (Chinese, Japanese, Korean and Thai).

Design/methodology/approach

Using 86,015 tweets referring to Asian restaurants, this research used text mining and sentiment analysis to find meaningful patterns, popular words and emotional states in opinions.

Findings

Twitter users held mingled perceptions of different types of Asian restaurants. Sentiment analysis and ANOVA showed that the average sentiment scores for Chinese restaurants was significantly lower than the other three Asian restaurants. While most positive tweets referred to food quality, many negative tweets suggested problems associated with service quality or food culture.

Research limitations/implications

This research provides a methodology that future researchers can use in applying social media analytics to explore major issues and extract sentiment information from text messages.

Originality/value

Limited research has been conducted applying social media analysis in hospitality research. This study fills a gap by using social media analytics with Twitter data to examine the Twitter users’ thoughts and emotions for four different types of Asian restaurants.

Abstract

Purpose

The purpose of this paper is twofold: first, to investigate strategies that external stakeholders can employ to affect construction project outcomes and, second, to identify essential requirements for utilising each strategy.

Design/methodology/approach

A new theoretical framework of stakeholder influence strategies was proposed and applied. The research design is a multi-case study, comprising four cases in the construction industry in Vietnam.

Findings

Seven specific strategies were found, including inputs withholding, inputs compromising, communication, direct action, coalition building, conflict escalation and credibility building. When possessing project inputs, stakeholders can affect a project directly via a withholding or compromising strategy. Communication is available to those who have basic communicating skills; however, direct action is only employed by groups that include a large number of members. Objectors must have common interests or goals with their potential allies for using coalition building. Conflict escalation is restricted to communities having distinctive characteristics which can be used to create new problems sensibly, while credibility building is used by parties possessing adequate resources and expertise.

Research limitations/implications

This study’s generalisability may be limited by the main source of data and the types of projects in the selected cases.

Practical implications

This study provides directions for project managers to predict stakeholder influence by taking project inputs and utilisation requirements of the strategies into consideration.

Originality/value

This study is one of the first investigations on stakeholder-attributes-related requirements for utilising influence strategies in projects.

This review aims to focus on recent reported research work on the construction and function of different electrochemical DNA biosensors. It also describes different sensing materials, chemistries of immobilization probes, conditions of hybridization and principles of transducing and amplification strategies.

Design/methodology/approach

The human disease-related mutated genes or DNA sequence detection at low cost can be verified by the electrochemical-based biosensor. A range of different chemistries is used by the DNA-based electrochemical biosensors, out of which the interactions of nanoscale material with recognition layer and a solid electrode surface are most interesting. A diversity of advancements has been made in the field of electrochemical detection.

Findings

Some important aspects are also highlighted in this review, which can contribute in the creation of successful biosensing devices in the future.

Originality/value

Drawing on the cognitive-functional model of emotions and emotional contagion, the authors aim to examine the role of negative emotions in the diffusion of cancer tweets.

Abstract

Purpose

Drawing on the cognitive-functional model of emotions and emotional contagion, the authors aim to examine the role of negative emotions in the diffusion of cancer tweets.

Design/methodology/approach

Using an integrated approach of social network and text analytics, the authors analyzed 142,883 cancer tweets from February to March 2018. The roles of negative emotions, emotional contagion, cancer themes and user influence on the diffusion of cancer tweets were examined.

Findings

Results indicated that cancer tweets expressing negativity and anger diffused more widely, while those expressing sadness or fear were less likely to diffuse. However, contrary to the authors’ expectation, cancer tweets expressing negative emotions (i.e. negativity, anger and fear) were less likely to arouse similar emotions among retweets, thus suggesting that emotions in cancer tweets were not as contagious as they seemed. Finally, user influence was the most important factor explaining the diffusion of cancer tweets, although cancer-related themes (i.e. affective, informative and social) had marginal effects on likelihood of diffusion.

Originality/value

Using a novel integrated social network–text analytics approach, the authors found that to understand cancer tweets' diffusion, it is critical to go beyond examining the content of tweets about cancer and the influence of messengers – the virality of cancer tweets is inextricable from the negative emotions.

Abstract

Purpose

The purpose of this study is to systematically review the literature on the intersections among family, migration and entrepreneurship in the context of Vietnam. This paper aims to shed light on the current state of knowledge of the research field by highlighting some key bibliographic trends among existing literature, mapping existing knowledge in the field of research and recommending future research agenda.

Design/methodology/approach

This study adopts a systematic literature review approach with five steps. A list of 24 papers that are extracted from a pool of 643 papers in the Core Collection of Web of Science and Scopus were selected as the most relevant to the research questions used for further in-depth analysis.

Findings

Bibliometric analysis indicates that this research field is considered an infant research stream that is dominated by qualitative empirical studies. Content analysis reveals how Vietnamese migrant families mobilize and use various kinds of cultural, social, human and financial capital for entrepreneurship. They also generate resources to develop family-owned enterprises that are expected to be continued over generations. Five research gaps for future research are identified: functions of family, downsides of networks, the role of transnational and returnee entrepreneurs, gender and methodology.

Research limitations/implications

The choice of a limited number of keywords and access to only two databases (Web of Science and Scopus) are limitations of this study. Furthermore, the selection of the articles for content analysis is subjective although research triangulation is applied in this review.

Originality/value

This research is a pioneering systematic literature review that sheds light on the interconnectedness of family, migration and entrepreneurship in the case of Vietnamese migrant entrepreneurs.

Abstract

Purpose

This study aims to redefine the urban heritage value of trade streets in Hanoi's Ancient Quarter (AQ) and propose an expanded notion of the “historicity” found through intangible cultural heritage (ICH).

Design/methodology/approach

A longitudinal analysis was conducted to examine the historical transitions of trade streets, thereby providing an alternative value perspective for considering the area's conservation management. The trade streets were specifically analysed from the pre-colonial era to 2017 using past survey data concerning the distribution and concentration of trade types, statistical documents from the colonial era and recent fieldwork data from investigations into 79 trade streets, thus identifying seven patterns of change.

Findings

Individual trade streets contribute to the unique identities of their respective streets while collectively providing experiential value through the overall variety and density of trade types. Further, the value of modernised trade streets can be found in their support of the area's systemic and experiential values.

Practical implications

Current management approaches should shift to include non-traditional trade streets that have experienced gradual changes or retained specific businesses for long periods of time.

Originality/value

This was the first study to conduct a longitudinal analysis of AQ trading with partial support from statistical data. It explored an expanded way of interpreting historicity from the viewpoint of dynamic ICH along the two axes of pace and intensity by tracing changes in commercial activities over time.

Abstract

Reforms of the Vietnamese economy have been widely credited for stabilizing the value of the state-issued currency in the marketplace. Nevertheless, how people evaluate the Vietnamese dong as a symbolic form can be read as a symptom of shifting economic and political forces, above all in Ho Chi Minh City, a city associated with commerce. Through three ethnographic cases – the introduction of “big money,” the scarcity of “new money” in 2002, and the campaign to build Automated Teller Machines (ATMs), this paper analyzes the contentious politics around symbolic exchange that shape confidence in Vietnamese currency.
