Sliding mode predictive control of a five-level rectifier with only four–IGBT
Authors: Zhu Yifeng , Zhang Ziyang , Zhao Hailong , Li Shaoling 
Published: September 2022

Purpose
Five-level rectifiers have received widespread attention because of their excellent performance in high-voltage and high-power applications. Taking a five-level rectifier with only four-IGBT for this study, a sliding mode predictive control (SMPC) algorithm is proposed to solve the problem of poor dynamic performance and poor anti-disturbance ability under the traditional model predictive control with the PI outer loop.

Design/methodology/approach
First, mathematical models under the two-phase stationary coordinate system and two-phase synchronous rotating coordinate system are established. Then, the design of the outer-loop sliding mode controller is completed by establishing the sliding mode surface and design approach rate. The design of the inner-loop model predictive controller was completed by discretizing the mathematical model equations. The modulation part uses a space vector modulation technique to generate the PWM wave.

Findings
The sliding mode predictive control strategy is compared with the control strategy with a PI outer loop and a model predictive inner loop. The proposed control strategy has a faster dynamic response and stronger anti-interference ability.

Originality/value
For the five-level rectifier, the advantages of fast dynamic influence and parameter insensitivity of sliding mode control are used in the voltage outer loop to replace the traditional PI control, and which is integrated with the model predictive control used in the current inner loop to form a novel control strategy with a faster dynamic response and stronger immunity to disturbances. This novel strategy is called sliding mode predictive control (SMC).

Published: September 2022

Purpose
Financial Technology (FinTech) innovations enable the provision of financial services to many unbanked across the world by increasing access. The key role of FinTech to drive financial inclusion however suffers significant impediments including the digital divide. Nevertheless, there is paucity of elaborate theories on financial inclusion while extant literature on FinTech only identify factors that drive its acceptance and use with little attention to inhibitors such as the digital divide. This study aims to investigate the impact of FinTech usage on financial inclusion amid the digital divide.

Design/methodology/approach
This study uses the unified theory of acceptance and use of technology (UTAUT2) and the model of digital inequality. A structural equation modeling technique is applied to data collected from 282 respondents in an online survey.

Findings
The findings confirm a positive influence of FinTech use on financial inclusion as well as the influence of performance expectancy and facilitating conditions on behavioral intentions. The results also show that digital divide measured with access, resource and force moderate the use of FinTech.

Originality/value
This study presents a theoretical model which is unique given that UTAUT2 was combined with digital divide moderators from the model of digital inequality to explain how FinTech usage impacts on financial inclusion. Addressing the research questions has led several theoretical contributions including the extension of the applicability of UTAUT2.

Authors: Hassanain Mohammad A. , Al-Harogi Mohammed , Sanni-Anibire Muizz O. 
Published: September 2022

Purpose
This research aims to examine the practice of design for safety (DfS) in the construction industry of Saudi Arabia.

Design/methodology/approach
The study has adopted a mixed-method approach through the use of questionnaire surveys administered to professionals in architecture and engineering firms, as well as follow-up interviews with selected participants. The participants consisted of architects, structural engineers and electromechanical engineers. The study investigated dimensions related to knowledge and awareness, attitude toward DfS implementation and critical success factors for DfS implementation. These various dimensions have been assessed accordingly through the mean ratings in the relevant section of this paper. The thematic responses obtained from the follow-up interviews have been summarized and presented.

Findings
The findings from this study reveal a high level of awareness of DfS in Saudi Arabia. It also revealed that the most influential critical success factors are legislation and awareness of stakeholders, whereas the major barrier is the fear of cost overruns by the clients and their representatives.

Originality/value
The design stage of construction projects is crucial to enhancing the safety performance of projects through effective control of hazardous situations. The concept of DfS is, however, immature in many countries, such as Saudi Arabia, due to lack of awareness, enabling policies and other barriers. The value of this study is that it shows the current level of knowledge and practice of DfS in architecture and engineering firms in Saudi Arabia and consequently triggers the interest of stakeholders in its adoption and implementation.

Authors: Neves Maria Elisabete , Cancela Beatriz Lopes , Gabriel Vítor Manuel de Sousa 
Published: September 2022

Purpose
This study aims to understand which factors determine the corporate performance of Portuguese and Spanish listed companies between 2011 and 2018, also considering the sub-period marked by the presence of the Troika in Portugal, between 2011 and 2014.

Design/methodology/approach
To achieve this aim, panel data methodology was used, specifically the generalized method of moments (GMM) estimation method proposed by Arellano and Bond (1991), Arellano and Bover (1995) and Blundell and Bond (1998) for 110 non-financial companies from the Iberian Peninsula.

Findings
The results point out different signs and significance of the variables in the companies of the two countries. Regarding the sub-period, our results suggest that the intervention of the Troika in Portugal acted in a very different way from the neighboring country.

Originality/value
This research shows the importance of studying countries individually, even with small dimensions, to reinforce the path that is still necessary for more sustainable companies. Furthermore, when companies have strong governance structures, the harmful contagion from one neighboring country to another may not happen.

Authors: Khan Arshad Ahmad , Khan Sufyan Ullah , Ali Muhammad Abu Sufyan , Khan Aftab , Hayat Yousaf , Luo Jianchao 
Published: September 2022

Purpose
The main aim of this study is to investigate the impact of climate change and water salinity on farmer’s income risk with future outlook mitigation. Salinity and climate change are a threat to agricultural productivity worldwide. However, the combined effects of climate change and salinity impacts on farmers' income are not well understood, particularly in developing countries.

Design/methodology/approach
The response-yield function and general maximum entropy methods were used to predict the impact of temperature, precipitation and salinity on crop yield. The target minimization of total absolute deviations (MOTAD)-positive mathematical programming model was used to simulate the impact of climate change and salinity on socioeconomic and environmental indicators. In the end, a multicriteria decision-making model was used, aiming at the selection of suitable climate scenarios.

Findings
The results revealed that precipitation shows a significantly decreasing trend, while temperature and groundwater salinity (EC) illustrate a significantly increasing trend. Climate change and EC negatively impact the farmer's income and water shadow prices. Maximum reduction in income and water shadow prices was observed for A2 scenario (−12.4% and 19.4%) during 2050. The environmental index was the most important, with priority of 43.4% compared to socioeconomic indicators. Subindex amount of water used was also significant in study area, with 28.1% priority. The technique for order preference by similarity to ideal solution ranking system found that B1 was the best climatic scenario for adopting climate change adaptation in the research region.

Originality/value
In this study, farmers' income threats were assessed with the aspects of different climate scenario (A1, A1B and B1) over the horizons of 2030, 2040 and 2050 and three different indicators (economic, social and environmental) in Northwestern region of Pakistan. Only in arid and semiarid regions has climate change raised temperature and reduced rainfall, which are preliminary symptoms of growing salinity.

Published: September 2022

Purpose
The purpose of this study is to fill a gap in literature with a meta-analysis of previous studies assessing the decision-making processes of travellers when choosing holiday destinations in times of crisis.

Design/methodology/approach
This study presents here an abductive analysis of the findings of 737 peer-reviewed studies published in leading hospitality and tourism journals between 1978 and 2020. The studies in question concentrate on tourist typologies and behaviours when making destination choices in times of crisis, and the garnered data was subjected to a computer-aided data analysis adopting a thematic analysis technique, making use of Leximancer software.

Findings
The data was subjected to a thematic analysis and clustered under five main categories based on the distribution of articles by publication year, research topic, author contributions, articles by journal and articles by country (e.g. tourist typology, travellers’ decision-making, holiday decision-making, tourist decision-making, destination choice, traveller behaviour and vacation decision-making).

Research limitations/implications
The limitations of this study include its inclusion only of articles listed in the SCOPUS, Web of Science and ScienceDirect databases. This study makes a critical assessment of the current gaps in literature and proposes questions to be raised in future studies.

Originality/value
This study proposes several topics for future investigation that are considered necessary to close crucial gaps in our understanding of the tourism sector’s response to behavioural trends. The authors’ intention in this regard is to increase the scholarly awareness of decision-making models relevant to destination choice by linking tourist typologies and the behaviour exhibited before, during and after crises.
News coverage vs sentiment: evaluating German residential real estate markets
Authors: Ploessl Franziska , Just Tobias 
Published: September 2022

Purpose
To investigate whether additional information of the permanent news flow, especially reporting intensity, can help to increase transparency in housing markets, this study aims to examine the relationship between news coverage or news sentiment and residential real estate prices in Germany at a regional level.

Design/methodology/approach
Using methods in the field of natural language processing, in particular word embeddings and dictionary-based sentiment analyses, the authors derive five different sentiment measures from almost 320,000 news articles of two professional German real estate news providers. These sentiment indicators are used as covariates in a first difference fixed effects regression to investigate the relationship between news coverage or news sentiment and residential real estate prices.

Findings
The empirical results suggest that the ascertained news-based indicators have a significant positive relationship with residential real estate prices. It appears that the combination of news coverage and news sentiment proves to be a reliable indicator. Furthermore, the extracted sentiment measures lead residential real estate prices up to two quarters. Finally, the explanatory power increases when regressing on prices for condominiums compared with houses, implying that the indicators may rather reflect investor sentiment.

Originality/value
To the best of the authors’ knowledge, this is the first paper to extract both the news coverage and news sentiment from real estate-related news for regional German housing markets. The approach presented in this study to quantify additional qualitative data from texts is replicable and can be applied to many further research areas on real estate topics.

Authors: Ansong Abraham , Ennin Ethel Esi , Yeboah Moses Ahomka 
Published: September 2022

PurposeThe study investigated the effects of relational leadership on hotel employees' creativity, using knowledge-sharing behaviour and leader–follower dyadic tenure as intervening variables.Design/methodology/approachA self-administered questionnaire was used to collect data from 355 employees of authorized hotels from the conurbation of Cape Coast and Elmina in Ghana. To evaluate the study's research hypotheses, the authors used WarpPLS and PLS-SEM.FindingsThe findings demonstrated that while knowledge-sharing behaviour did not directly affect employee creativity, it did have a significant mediating effect on the link between relational leadership and the creativity of employees. The study also revealed that the ability of relational leaders to drive knowledge-sharing behaviour was not contingent on leader–follower dyadic tenure.Practical implicationsThe results of this study have practical relevance for human resource practitioners in the hospitality industry. Given that relational leadership has a positive relationship with employee creativity, the authors recommend that hotel supervisors relate well with employees by sharing valuable information and respecting their opinions in decision-making.Originality/valueStudies on the role of relational leadership and employee creativity are scanty. This study develops a model to explain how relational leadership could influence employee creativity by incorporating knowledge-sharing behaviour and leader–follower dyadic tenure.
