Abstract

Purpose

The objective of this study is to investigate the role of blockchain in reducing the impact of barriers to humanitarian supply chain management (HSCM) using a list of blockchain benefits.

Design/methodology/approach

A decision aid was used to explore the suitability of blockchain in humanitarian supply chains. To achieve that, first, a list of barriers to HSCM was identified. Then, the intuitionistic fuzzy decision-making trial and evaluation laboratory (IF–DEMATEL) method was utilized to determine the relationships and the level of interdependencies among the criteria. Finally, the intuitionistic fuzzyanalytic network process (IF–ANP) technique was employed, as it successfully handles dependencies among the criteria.

Findings

The findings of this study suggest that interorganizational barriers are the most suitable ones, the impacts of which blockchain may alleviate. This study further suggests that trust turned out to be the most significant benefit criterion for the analysis.

Research limitations/implications

The readers should construe the findings of this study with caution since it was carried out using the data collected from the experts of a particular country. Moreover, the proposed decision aid contemplates a limited set of criteria to assess a possible role of blockchain in overcoming the barriers to HSCM.

Practical implications

The findings of this study can assist humanitarian supply chain managers to make more judicious assessments on whether they implement the blockchain in humanitarian supply chain operations. Specifically, this research may help decision makers to identify the certain barriers, the impact of which may be reduced by using the blockchain. The findings of this research will also help various decision makers make more rational decisions and allocate their resources more effectively.

Originality/value

To the best of authors’ knowledge, no single study exists to investigate the role of blockchain in reducing the impact of barriers to HSCM using an intuitionistic fuzzy multi-criteria decision-making approach.

Abstract

Purpose

The objective of this study is to assess quantitatively how feasible blockchain is for various industries, such as logistics and supply chain, health, energy, finance, automotive, pharmaceutical and agriculture and food using a comprehensive list of indicators.

Design/methodology/approach

A decision aid was applied to the problem of identifying the feasibility of blockchain in Turkish industries. To this end, first, a set of indicators was identified. Then, the fuzzy AHP and fuzzy TOPSIS were utilized to assess the feasibility comparatively using the data gathered from a group of experts. Finally, a scenario analysis was conducted to ensure the consistency of our evaluation.

Findings

The findings of this study suggest that comparatively, logistics and supply chain, finance and health industries are the most feasible industries for blockchain. This study further suggests that blockchain is the least feasible for the automotive industry compared to the rest of the identified industries.

Research limitations/implications

It is cumbersome to find out the respondents who have sufficient knowledge of both blockchain and the identified industries. Even if we took the utmost care in identifying the right respondents, we limited our search to the biggest industrial hubs of Turkey.

Practical implications

The findings of this research may help various decision-makers employed in governments, conglomerates, software and consulting firms and national research institutions make more informed decisions and allocate their resources more effectively.

Originality/value

To this date, the current studies have solely investigated possible research opportunities in blockchain and demonstrated several blockchain applications in stand-alone cases. To the best of our knowledge, however, no single study exists that evaluates the feasibility of blockchain comparatively and holistically among a group of industries using various indicators.

Abstract

Purpose

The purpose of this research is to determine the competitive advantages of higher education institutions (HEIs) and create a new methodology to rank universities according to the competitive advantages.

Design/methodology/approach

The research determines the competitive advantages of HEIs by analysing expert opinions through a semi-structured interview form, matches codes and themes to performance indicators using Saldana's two-cycle coding methods, evaluates content validity through Lawshe and reveals the item weights of the ranking with analytical hierarchy process (AHP). Simple additive weighting (SAW) and Technique for Order of Preference by Similarity (TOPSIS) methods were used for ranking universities.

Findings

Seven dimensions stand out in regard to what should be considered while ranking HEIs: research and publication, education, management, infrastructure, financial resources, human resources and social and economic contribution. Under the 7 dimensions, 69 indicators were determined.

Practical implications

The research provides a scientific reference point where HEIs can compare themselves with other HEIs regarding where they are in the sector, especially in terms of competitive advantages.

Originality/value

Although there are many different ranking methods that rank universities in the national and international literature, almost all these methods are largely based on the outputs of the university such as the number of publications, the number of patents, the number of projects, etc. A framework which ranks universities by considering different aspects of the institution, such as management, human resources and financial resources, has not been developed yet. In this respect, this research aims to fill this gap in the literature.

Abstract

Purpose

This paper aims to determine the knowledge and attitudes of the physicians regarding human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS), to emphasize that these patients exist and they will exist in the future and to raise awareness so as to prevent that their rights to treatment are revoked.

Design/methodology/approach

The survey was conducted via a link sent through an online system. Random physicians from 81 cities of the country were invited to the survey. The survey has 41 questions regarding knowledge and attitudes in total, including epidemiological information such as age, gender and title.

Findings

A total of 3,107 physicians has voluntarily participated in the study. In total, 2,195 (70.7%) are internal physicians and 912 (29.3%) are surgical physicians among the participant physicians. In total, 1,452 (46.7%) of the participants are specialist physicians, 608 (19.6%) of the participants are practising physician and the rest of it is physician assistants, academicians and dentists, respectively.

Originality/value

In this study, it has been found out that the physicians have a lack of knowledge on HIV/AIDS and they adopt a discriminatory attitude towards HIV-positive persons. HIV-positive patients who are exposed to discrimination and scared of being uncovered refrain from applying to hospitals for treatment, which puts public health into jeopardy due to the high viral load and these patients are faced with difficulties in coping with both medical and emotional load of the disease.

Abstract

Purpose

Given that online search visibility is influenced by various determinants, and that influence may vary across industries, this study aims in investigating the major predictors of online search visibility in the context of blood banks.

Design/methodology/approach

To formalize the online visibility, the authors have found theoretical foundations in activity theory, while to quantify online visiblity the authors have used the search engine optimization (SEO) Index, ranking, and a number of visitors. The examined model includes ten hypotheses and was tested on data from 57 blood banks.

Findings

Results challenge shallow domain knowledge. The major predictors of online search visibility are Alternative Text Attribute (ALT) text, backlinks, robots, domain authority (DA) and bounce rate (BR). The issues are related to the number of backlinks, social score, and DA. Polarized utilization of SEO techniques is evident.

Practical implications

The methodology can be used to analyze the online search visibility of other industries or similar not-for-profit organizations. Findings in terms of individual predictors can be useful for marketers to better manage online search visibility.

Social implications

The acute blood donation problems may be to a certain degree level as the information flow between donors and blood banks will be facilitated.

Originality/value

This is the first study to analyze the blood bank context. The results provide invaluable inputs to marketers, managers, and policymakers.

Abstract

Purpose

The purpose of this paper is twofold. First, it aims to analyze the individual influence of different knowledge management practises (KMP) on firm performance. Second, it aims to analyze the mediating role of organizational learning (OL) between each KMP and performance.

Design/methodology/approach

A telephone-survey was applied in 2018 to the managers of 400 Spanish firms. The data retrieved was analyzed by using multiple regression analysis.

Findings

Knowledge generation (KG) and knowledge flow (KF) promote firm performance, while there is not a direct association between knowledge storage and performance. OL mediates the relationship between KG and performance, as well as between KF and performance.

Research limitations/implications

First, this research confirms that not all the KMP have a direct effect on firm performance, thus, future research would need to differentiate between different KMP. Second, this paper is pioneering in providing empirical evidence that OL mediates the KMP – performance relationship. Third, the empirical study was performed in a context non-researched yet by the literature considering KMP individually: Spain.

Practical implications

First, besides the results managers should focus their efforts in practises related to KG and application. Second, OL mediating suggests that managers should invest in managerial commitment to promote a shared culture, shared vision, open-mind to new ideas and a lot of dialogue.

Originality/value

This is the first study that investigates how KMP contribute to firm performance by incorporating the mediating impact of OL. The results will help organizations to identify the KMP improving the performance.

Abstract

Purpose

This study tested a moderated mediation model of school leadership effects on teacher instructional practices. Specifically, the authors focused on the mediating effect of teacher professional communities and the moderating effect of instructional climate on the relationship between school leadership and teacher instructional practices.

Design/methodology/approach

The authors collected data from 958 teachers working in 72 middle and high schools in Türkiye and employed multilevel structural equation modelling (MSEM) with Bayesian estimation to predict structural links between the study variables.

Findings

Results affirmed a full mediation model where school leadership practices exerted indirect effects on teacher instructional practices through promoting teacher professional communities. The authors also found significant moderating role of instructional climate in the effect of school leadership on teacher professional communities and instructional practices.

Originality/value

This study illuminates the contextualized nature of school leadership by concluding that the effect of school leadership on teacher professional communities and instructional practices is closely tied to the extent to which a high-quality instructional climate is established in schools.

Abstract

Purpose

The current study seeks to explore the links between principal self-efficacy, openness to change, well-being, and transformational leadership. Specifically, we tested a mediated-effects model where principal self-efficacy and openness to change were treated as independent variables, well-being as mediator, and transformational leadership as dependent variable.

Design/methodology/approach

Survey data were collected from 351 principals employed in Turkish schools and analysed using confirmatory factor analysis and structural equation modelling.

Findings

The results suggested the direct empirical relationship of principal self-efficacy and openness to change with transformational leadership, and indirect through professional well-being.

Originality/value

Our study enriched our understanding of school leadership by elucidating the potential mechanisms that underpin the implementation of transformational leadership practices.

Abstract

Purpose

This study investigated the micro–macro link in the hospitality and tourism (H&T) sector, specifically considering whether the gender diversity, independence and board attendance rates of H&T firms' boards, alongside the moderation effect of board policies, played a significant role in tourism sector performance.

Design/methodology/approach

The 2011–2018 data were retrieved from the World Bank and the Thomson Reuters Eikon databases, and fixed effects panel regression was conducted.

Findings

While female directors were a significant driver of tourism sector performance in terms of tourist arrivals and tourism receipts, independent directors were effective in improving tourist arrivals only. Furthermore, moderation analyses demonstrated the inefficacy of board policies in enhancing these directors' contributions to the sector's development. Moreover, the findings revealed the inefficiency of board meetings.

Practical implications

Concerning the efficacy of board policies, the results suggest that firms' boards should review and revise their policies. Surprisingly, while board-diversity policies made no difference to female directors' role in the sector's development (although females were influential), board-independence policies produced unexpected results. In the absence of a board-independence policy, independent directors are influential, but if a policy exists, they are not.

Originality/value

Although prior firm-level studies tested whether board characteristics enhanced firms' performance in the H&T sector, they did not investigate whether board characteristics promoted tourism sector performance. Moreover, the moderating effect of board policies on boards' structures and tourism sector performance has not yet been examined.
