Performance analysis of boost converter with cascaded inner loop fuzzy SMC
Authors: Yoganathan Rekha , Venkatesan Jamuna , I. William Christopher 
Published: February 2021

Purpose
This paper intent to design, develop, and fabricate a robust cascaded controller based on the dual loop concept i.e. Fuzzy Sliding Mode concept in the inner loop and traditional Proportional Integral controller in the outer loop to reduce the unknown dynamics and disturbances that occur in the DC-DC Converter.

Design/methodology/approach
The proposed Fuzzy sliding mode approach combines the merits of both SMC and Fuzzy logic control. FSMC approach reduces the chattering phenomena that commonly occurs in the sliding mode control and speed up the response of the controller.

Findings
In most of the research work, the inner current loop of cascaded controller was designed by sliding mode control. In this paper FSMC is proposed and its efficacy is confirmed with SMC -PI. In most uncertainties, FSMC-PI produces null maximum peak overshoot and a very less settling time of 0.0005 sec.

Originality/value
The presence of Fuzzy SMC in the inner loop ensure satisfactory response against all uncertainties such as steady state, circuit parameter variations and sudden line and load disturbances.

PurposeEffective procurement of infrastructure is linked to the attainment of the sustainable development goals set by the United Nations. While the capacity of organisations is generally thought to be related to organisational performance, there is a lack of empirical insights concerning the contribution of procurement capacity of public organisations towards the attainment of procurement objectives in infrastructure procurement. Thus, it is unclear which aspects of the capacity of public procurement organisations contribute the most to the attainment of procurement objectives in the procurement of infrastructure. This research sought to address this gap.Design/methodology/approachThe research used a survey of public procurement professionals which yielded 590 responses.FindingsExploratory factor analysis of 23 organisational capacity items revealed three components of organisational procurement capacity: “management of the procurement process”; “human and physical resources”; and “financial resources and management”. Multiple regression modelling of the relationship between the components and the attainment of 12 procurement objectives further reveals that there is a significant positive relationship between the three components and all the objectives. However, “management of the procurement process” emerged as the greatest contributor to the attainment of seven objectives, whereas “human and physical resources”, and “financial resources and management” were the greatest contributor to the attainment of one objective and four objectives, respectively.Originality/valueThe study provides strong empirical justification for investment in the development of procurement capacity of public agencies involved in procurement of infrastructure. Furthermore, procurement capacity development of specific capacity components can be prioritised based on the relative contribution of capacity components to the attainment of desired procurement objectives. This should be useful to government policymakers as well as multilateral organisations that fund infrastructure and procurement reforms in various countries.
The effect of online academic coaches on supporting graduate students’ performance in intensive online learning environments: a three-course comparison
Authors: Park Sunyoung , Robinson Petra A. 
Published: February 2021

Purpose
The purpose of this study is to examine how academic coaches, through academic student support, impact graduate student performance in a time-intensive online learning program for pursuing a master’s degree in leadership and human resource development in a research-intensive public university in the Southern USA.

Design/methodology/approach
The participants in this study were 435 graduate students enrolled in their online master’s degree program. Framed by the theory of transactional distance and by adopting a pre-experimental design and the analysis of variance (ANOVA) technique, the student performance in three courses was compared (principles of adult education, research methods and performance analysis) with academic coaches.

Findings
The findings indicate that the average score of students was higher when students received more feedback and comments from an academic coach than less feedback and comments in the performance analysis course. Students who had an academic coach in the adult education class performed better than those who did not have a coach. However, there was not a significant difference in academic performance based on the number of academic coaches (one versus three) in the research methods course.

Originality/value
This preliminary work may lead to a better understanding of how academic coaches can best support adult learners in their pursuits of online postsecondary education. This study would suggest implications for online instructors and institutions to enhance student success and retention in online learning activities by using academic coaching.
A novel approach to the creation of a labelling lexicon for improving emotion analysis in text
Authors: Segura Navarrete Alejandra , Martinez-Araneda Claudia , Vidal-Castro Christian , Rubio-Manzano Clemente 
Published: February 2021

PurposeThis paper aims to describe the process used to create an emotion lexicon enriched with the emotional intensity of words and focuses on improving the emotion analysis process in texts.Design/methodology/approachThe process includes setting, preparation and labelling stages. In the first stage, a lexicon is selected. It must include a translation to the target language and labelling according to Plutchik’s eight emotions. The second stage starts with the validation of the translations. Then, it is expanded with the synonyms of the emotion synsets of each word. In the labelling stage, the similarity of words is calculated and displayed using WordNet similarity.FindingsThe authors’ approach shows better performance to identification of the predominant emotion for the selected corpus. The most relevant is the improvement obtained in the results of the emotion analysis in a hybrid approach compared to the results obtained in a purist approach.Research limitations/implicationsThe proposed lexicon can still be enriched by incorporating elements such as emojis, idioms and colloquial expressions.Practical implicationsThis work is part of a research project that aids in solving problems in a digital society, such as detecting cyberbullying, abusive language and gender violence in texts or exercising parental control. Detection of depressive states in young people and children is added.Originality/valueThis semi-automatic process can be applied to any language to generate an emotion lexicon. This resource will be available in a software tool that implements a crowdsourcing strategy allowing the intensity to be re-labelled and new words to be automatically incorporated into the lexicon.

Purpose
The purpose of this paper is to determine the digital library usage patterns as a means of improving the system, as well as the user experience, to give appropriate recognition to the most popular dissertations’ authors and to measure the interest of non-academic users for dissertations defended at the University of Novi Sad (UNS).

Design/methodology/approach
A logging module of the digital library of theses and dissertations of University of Novi Sad (PHD UNS) application has been implemented. The module recorded the messages relating to the search queries and downloads over a three-year period from 2017–2019. These logs are analysed using the Elasticsearch, Logstash and Kibana (ELK) technology stack and the results are shown using graphs and tables.

Findings
The analysis determined the perfect time for weekly maintenance of the system, defined a recommendation for improving the system and revealed the most popular dissertations. A significant number of downloads and queries originated from citizens, i.e. users outside the academic community.

Practical implications
The conducted analysis defined recommendations for the system improvement which can be used by PHD UNS research and development (R&D) team and revealed the most popular dissertations which are used for the promotion of its authors through faculties’ websites.

Originality/value
To the best of the authors’ knowledge, this is the first study of ELK based log analysis of a Serbian language documents’ repository. Besides, the value of results for the PHD UNS R&D team and UNS rector team, the study proves that PhD digital library presents an important Open Science communication channel for presenting scientific results to the citizens.

The proposed critical asset assessment ranking will benefit health-care facility organizations by assessing their asset performance according to capital renewal needs.

Originality/value
This study offers a novel conceptual framework to understand and determine rank critical asset assessment factors for health-care facilities.
Modelling bioeconomy futures for Eastern Africa
Authors: Gatune Julius , Ozor Nicholas , Oriama Ruth 
Published: February 2021

Purpose
This paper aims to explore the potential of Bioeconomy as a pathway for sustainable transformation of economies of East Africa. Although East Africa region has shown good growth, this has been accompanied by rising concerns about sustainability, as population growth is putting significant strain on biodiversity undermining capacity for future growth. The search for a new growth pathways points to leveraging bioeconomy. To get insights on the viability of this pathway, this study simulated several scenarios to help inform a regional bioeconomy strategy.

Design/methodology/approach
To get insights into the viability of this pathway, a conceptual model to capture demand and supply drivers was constructed and simulations were conducted by using the International Futures (IFs) modelling platform.

Findings
The analysis points to the potential of a bioeconomy-driven economic strategy to drive transformation. However, the simulation points to the fact that if not well thought out, it can also be costly in terms of environment, and indeed such a strategy can lead to a disaster in the long run. It is also clear that having a strong Bioeconomy does not necessarily mean being self-sufficient in agricultural production. If saving the forests or increasing forest cover means agricultural imports rise this should be fine. Also, a strong Bioeconomy does not necessarily mean development objectives are fully met.

Research limitations implications
The IFs platform is a general platform and thus cannot capture the specific enablers for a Bioeconomy. So strategy development should use the result as starting point.

Practical implications
Also, a strong bioeconomy does not necessarily mean that development objectives are fully met. A bioeconomy strategy should be part of package of strategy to ensure sustainable and inclusive growth.

Originality/value
While Bioeconomy is increasingly gaining attention, many countries have proposed strategies the analysis tends to be qualitative. No quantitative simulation of this new economic pathways has yet been conducted in East Africa. The IFs platform is a general simulation platform; therefore, the parameters available in the model cannot fully capture what Bioeconomy is. This analysis needs to be supplemented by a qualitative scenarios analysis.
Integration of records management systems at a South African water utility company
Authors: Ngoepe Mpho , Mello Vincent 
Published: February 2021

Purpose
Digital records are either stored in an enterprise resource planning (ERP) or an electronic content management (ECM) system or managed without the benefit of either. To achieve high productivity, integration of these systems is required. However, the utilisation of either an ERP or ECM system is absent in many organisations. The purpose of this paper is to explore the development of a framework that may support the integration of an ERP into an ECM system at Rand Water.

Design/methodology/approach
This qualitative study used a case design with 14 interviewees from different levels in the organisation and diverse business units using ERP and ECM to perform their operational deliverables. Purposive sampling was used to select the interviewees in line with their area of work, role and level of operation.

Findings
This study established that the water utility company has implemented an ERP system (SAP) since 2004 and ECM systems since 1991 (Papertrail and later IBM FileNet) with only the information flow module integrated. This study suggested that to integrate ERP into ECM, human and non-human actors need to collaborate to ensure large-scale integration.

Originality/value
This study presents a framework for integrating ERP into ECM. It is suggested that an integration module for ERPs called extended ECM, be considered. A further study of the transfer of digital records in ECM into archival custody is recommended.
Gender, sexual orientation, academic self-concept and leadership
Authors: Miles Jeffrey A. , Naumann Stefanie E. 
Published: February 2021

PurposeThe study's purpose is to present and empirically test a model that identifies academic self-concept as a mediator of the relationship between gender, sexual orientation and self-perceptions of leadership ability.Design/methodology/approachSurveys were administered to 964 first-year undergraduate students.FindingsAcademic self-concept mediated the relationship between gender and leadership for all subjects and for self-reported heterosexual subjects but not for self-reported nonheterosexual subjects.Research limitations/implicationsGender differences in leadership perceptions still exist and appear as early as the college years. The fact that academic self-concept did not mediate the relationship between gender and self-perceptions of leadership for nonheterosexual students might be explained by considering research that has identified different levels of gender conformity between straight and gay individuals.Practical implicationsStudent self-perceptions of leadership could be improved if opportunities were provided for students showing that people other than White, male, heterosexuals can also be effective leaders. When women and underrepresented groups attain leadership positions in the workplace, it attracts others because it sends a message that this organization welcomes women and underrepresented groups in positions of leadership.Originality/valueThis study addresses a gap in the field by using the social identity theory of leadership to integrate conflicting research streams in the existing literature and by proposing that academic self-concept underlies the relationship between gender, sexual orientation and self-perceptions of leadership. The study responds to Bark et al.'s (2016) call for future research to consider how highly prototypical individuals have a key advantage in people's perceptions of their leadership.
Stakeholder role in tourism sustainability: the case of Kwame Nkrumah Mausoleum and centre for art and culture in Ghana
Authors: Amoako George Kofi , Obuobisa-Darko Theresa , Ohene Marfo Sylvia 
Published: February 2021

PurposeThe paper examines the role of stakeholders in tourism and hospitality industry to ensure sustainability. This study focuses on investigating how stakeholders view can influence business sustainability in the tourism industry in Ghana and Africa. The study also looks at the future of sustainable tourism activities in Ghana and Africa.Design/methodology/approachA qualitative approach was adopted and interviewees were purposively selected. Using the semi-structured interview 12 people were interviewed and NVivo used to analyse the data. The study was carried out in Accra the capital city of Ghana. Using the stakeholder based theory and resource based theory (RBT) the study addresses how sustainable competitive advantage can be developed.FindingsResults shows how stakeholders involved such employees, government, community/society, private sector and individual shop owners perceive factors that enhance or limit progress in tourism. Some challenges they encounter include high level of illiteracy, lack of education for upcoming youth, low funding and publicity, lack of the enforcement of laws in the sector. The findings also indicated that to ensure sustainability in the industry the products should be unique, valuable, rare, non-substitutable and non-imitable and has to be advertised.Research limitations/implicationsResearchers encountered difficulties in eliciting answers from stakeholders who are experts and managers in the industry because of their busy schedules. The researcher admits that this research work which is carried out only in Ghana cannot be used to generalise an assumption for the entire industry sectors in Africa and beyond. The sample size could be improved and the study could be conducted in other African countries for the purposes of comparison.Practical implicationsThis study reveals how stakeholders view developments in the tourism sector and this can be used as a guide in developing policies and marketing strategies in the tourism industry. Both theoretical and managerial implications are discussed.Originality/valueVery little literature has been written on stakeholders' view on business sustainability in the tourism industry in Ghana. Moreover the use of stakeholder and resource based view theories application in developing competitive advantage in the developing country perspective is unique. The findings in no small way will somehow benefit the government and industry stakeholders by providing the latest views and perspectives in Ghana.
Measuring what matters? mapping higher education internationalization in the Asia–Pacific
Authors: Williams James H. , Brehm Will , Kitamura Yuto 
Published: February 2021

PurposeThis paper sought to understand at one time point what was known and not known about the status and use of indicators of internationalization of higher education in Asia–Pacific. More specifically, we identified and mapped publicly available indicators of international of higher education in the region. We examined the ways by which internationalization has been measured and the indicators used, setting up discussion of what may be missing from internationalization efforts.Design/methodology/approachThe primary questions were: (1) What are the current available sources of data in the Asia–Pacific region? (2) How is internationalization measured in publicly available databases and academic materials in Asia–Pacific? To answer these questions, we carried out a structured search of academic and agency literatures. Review of these literatures led us to develop definitions and a classification system by which indicators were classified and examined.FindingsIndicators clustered almost exclusively around measures of student mobility, neglecting a wide range of other possible measures. The authors discuss the implications for internationalization of higher education in the region and draw on existing critical literature to speculate why this might be the case, and what dimensions of internationalization are likely overlooked with such a limited focus.Originality/valueInternationalization of higher education has gained considerable momentum worldwide in recent years, and higher education in the Asia–Pacific region is arguably the world's most dynamic. Despite such dynamism, no research to our knowledge has mapped the way in which internationalization is measured by actors in the region.
The effect of repeated laundering on the softness and smoothness of terry-cloth towels using a sound spectrum analysis
Authors: Blaisdell Maruska Giselle Salvatierra , Yun Changsang 
Published: February 2021

PurposeThis study aims to examine the effect of laundering on the softness and smoothness of terry-cloth towels by different washing machine type, washing temperature, drying method and the use of fabric softener, using a newly developed sound spectrum analysis known as Textile Softness Analyzer.Design/methodology/approachThe experiment was designed to analyze the most significant laundering parameter in the reduction of softness and smoothness of terry cloth during one laundering cycle up to ten cycles by testing samples using TSA machine.FindingsA front-loading washer had a significant effect on reducing softness and smoothness in comparison to a top-loading machine; line-drying resulted in a higher decrease in softness and smoothness than tumble-drying. Washing temperature showed no significant effect, and the use of softener during washing was able to reduce the negative effect of line-drying on the softness and smoothness of terry cloth.Originality/valueThis paper provided information on the laundering parameters that can maintain the softness and smoothness of terry-cloth towels, and this was examined with sound spectrum analysis to measure softness and smoothness of textiles.
