Management commitment and its impact on occupational health and safety improvement: a case of iron, steel and metal manufacturing industries
Authors: Berhan Eshetie 
Published: May 2020

PurposeManagement commitments (MCs) have a prominent effect to create a safe work environment in the industries. Though there have been various studies on the prevalence and associated factors of OHS in Ethiopian manufacturing industries, the role of MCs in improving workplace safety, however, has not been studied so far. The purpose of this paper is, therefore, to investigate the role of MCs on improving OHS in iron, steel and metal manufacturing industries (ISMMI) in Addis Ababa.Design/methodology/approachThis paper used a close-ended questionnaire to collect primary data from 89 ISMMI and fitted the data in structural equation modelling (SEM) techniques using SPSS and AMOS.FindingsThe major findings of the study showed that directly or indirectly there are good MCs in Ethiopian ISMMI. To some extent, MCs have also resulted in reducing risk and diseases causing factors, which subsequently reduced occupational risks and disease. However, the study showed that MCs are not strategically supported.Research limitations/implicationsDue to the limited scope of data collection, the research results may not be equally implemented outside Addis Ababa and other sectors.Practical implicationsThe findings of the research may help policymakers and managers to strictly control MCs and follow up implementation of OHS policies.Originality/valueThis paper is the first of its kind in developing the conceptual framework model and attempting to assess MCs using structural equation model towards improving OHS in ISMMI.

Published: May 2020

PurposeThe recent global economic crisis affected workplaces in many countries, raising questions about the employees' situation. While most work-related studies in times of crises focus on job loss and unemployment, this study analyzes workplace violence in the wake of the 2008 economic crisis among municipal employees within care and education.Design/methodology/approachMixed method approach was used for data collection; longitudinal online surveys and focus group interviews were used.FindingsThe prevalence of workplace violence increased between the three time points of the study, in particular in downsized workplaces. A higher proportion of employees working in care were exposed to threats and physical violence than employees in education as clients of employees in care services were more likely to lash out against employees due to cutbacks in services. Focus groups interviews indicated that the causes of increased workplace violence may be due to a spreading effect both from within and outside the workplace.Practical implicationsAs workplace violence can have serious consequences for the health and well-being of employees, it is important for those who have responsibility for the work environment and occupational health in the workplace to design policies that take these findings into account.Originality/valueBased on the mixed methods, longitudinal survey and focus group interviews, this study contributes to knowledge on workplace violence in times of economic crises. It shows that the prevalence of workplace violence increased not only directly after the economic collapse but also continued up to five years later.
An acquisition or a greenfield subsidiary? The impact of knowledge on sequential establishments in a host country
Authors: Pehrsson Anders 
Published: May 2020

PurposeEstablishment of wholly owned subsidiaries in a foreign market is central to international marketing because sole ownership and high commitment facilitate firm's marketing in the local market. Drawing on knowledge-based theory, this study extends the current understanding of firm's sequential establishments of wholly owned subsidiaries in a host country.Design/methodology/approachSwedish firms' establishments of wholly owned subsidiaries in Germany, the United Kingdom and the United States were analyzed using a longitudinal approach.FindingsA firm's broad international experience is associated with an acquisition in any phase, while mode experience and value-adding experience are associated with postinitial acquisitions. There is no association between mode experience and greenfield investments.Research limitations/implicationsKnowledge-based theory explains a firm's choice of establishment mode when establishing in the same host country. Effects of marketing experiences are due to the establishment mode and different experiences explain choices for initial and postinitial establishments.Practical implicationsIn choosing between a wholly owned subsidiary in terms of an acquisition or a greenfield investment, for a foreign establishment the firm is advised to consider the impact of marketing experiences and establishment phase.Originality/valueResearch is needed on how experiences affect choices between foreign establishment modes where the firm is the sole owner. This study is the first to focus on the choice between wholly owned subsidiaries in terms of acquisitions and greenfield investments, and the impact of experience and phase of establishment in a particular host country.
New organizational forms in emerging economies: bridging the gap between agribusiness management and international development
Authors: Dentoni Domenico , Bijman Jos , Bossle Marilia Bonzanini , Gondwe Sera , Isubikalu Prossy , Ji Chen , Kella Chintan , Pascucci Stefano , Royer Annie , Vieira Luciana 
Published: May 2020

PurposeThis editorial article introduces and analyzes a variety of new organizational forms that rapidly emerged in Africa, Asia, Latin America and Eastern Europe in the latest two decades. Among the others, these include: business model partnerships, business platforms, incubators and hubs, public–private partnerships, agribusiness companies' foundations and spin-offs, short supply chains, community-supported agriculture and other community self-organizing experiences. Building upon the recent literature and the five selected papers in this special issue, the authors discuss what is novel in these organizations and why, when and how they emerge and evolve over time.Design/methodology/approachThe authors identify three elements that, when considered together, explain and predict the emergence and evolution of these new organizational forms: institutions, strategies and learning processes.FindingsThe authors demonstrate that societal actors seeking to (re)design these new organizational forms need to consider these three elements to combine the pursuit of their interests of their own constituencies with the sustainable development goals (SDGs).Originality/valueTaking stock from the literature, the authors invite future research on new organizational forms to take explicitly the pursuit of the SDGs into consideration; to build upon a process ontology; and to deeply reflect on our positionality of scientists studying and sometimes engaging in these organizations.
Operational research applied in the field of public security
Authors: Basilio Marcio Pereira , Pereira Valdecy 
Published: May 2020

Purpose
Because that the crime in a wide way impacts the life of the people in the big metropolis, researchers have treated the question from several angles. The purpose of the paper, under the umbrella of operational research, is to develop a model of the ordering of police strategies, in the fight against crime in general, according to a certain criminal demand.

Design/methodology/approach
For the construction of the impact matrix of the strategies under the reduction of crime rates, considering a portfolio of crimes, a questionnaire applied to specialists was used. In a second moment, defined the criteria and strategies to be ordered, the multicriteria ELECTRE IV method was used, which with the help of the J-Electre software emulated the systematized data in the impact matrix and produced the final ordering of the most efficient strategies, in the fight against crime, in the perception of decision-makers.

Findings
As a result, the research revealed that policing strategies directed at solving specific crimes are the most effective in the perception of decision-makers after the emulation of data with the ELECTRE IV method.

Research limitations/implications
As research implications, it can be inferred that the use of multicriteria methods in the modeling of problems in the area of public security can contribute to rationalization of the use of the means available in the fight against crime in large cities. The research showed that it is possible to use customized policing strategies to a certain reality.

Practical implications
The method presented in this research is directly related to the major strategies: problem-oriented policing and hot spot policing. This method allows public safety managers to consider the possibility of combining different law enforcement strategies in each context. In this sense, the use of the multiple-criteria decision analysis (MCDA) (ELECTRE IV) method allows the evaluation of a large set of alternatives according to a set of established criteria, speeding up the process and reducing subjectivity, allowing the manager to analyze several scenarios with greater clarity and impartiality and choosing an alternative that best solves the proposed problem. The expected result is the rationalization of the available means applied in the search for the reduction of crime rates.

Social implications
The customization of policing strategies, according to criminal demands, implies the efficient way to reduce criminal charges. Reducing criminal rates enables the development of the local economy, tourism and the quality of life of people by exercising their freedom to the full.

Originality/value
The originality lies in filling a gap in the literature with the elaboration of the impact matrix of policing strategies in reducing criminal indices, and in their associated use in ordering strategies through a multicriteria method.
A qualitative investigation on combined effects of distant leadership, organisational agility and digital collaboration on perceived employee engagement
Authors: Busse Ronald , Weidner Georg 
Published: May 2020

PurposeEnvironments coined as “VUCA” (volatility, uncertainty, complexity, ambiguity) are hotbeds for new modi operandi in organisations that involve a shift from face-to-face towards distant leadership, as well as from “classical” towards agile organisation principles.Design/methodology/approachAt the same time, digital collaboration tools have found their way into daily business operations. As the above changes arguably leave deep imprints on performance indicators, our work accordingly illuminates potential impacts on employee engagement. Based on a German sample, we conduct a qualitative investigation featuring in-depth interviews.FindingsOur findings indicate a curvilinear inverted (approximate) U-shaped relation between what we dub “leadership richness continuum” (including specific characteristics of leadership, agility, as well as the application of a digital collaboration tool) and engagement.Originality/valueAlthough our work may inspire practicing managers, we also contribute to theory development providing a new theoretical model for employee engagement.

Published: May 2020

Purpose
The purpose of this paper is to present a study on miniaturized instruments for analytical chemistry with a microplasma as the excitation source.

Design/methodology/approach
The atmospheric pressure glow microdischarge could be ignited inside a ceramic structure between a solid anode and a liquid cathode. As a result of the cathode sputtering of the solution, it was possible to determine its chemical composition by analyzing the emission spectra of the discharge. Cathodes with microfluidic channels and two types of anodes were constructed. Both types were tested through experimentation. Impact of the electrodes geometry on the discharge was established. A cathode aperture of various sizes and anodes made from different materials were used.

Findings
The spectroscopic properties of the discharge and its usefulness in the analysis depended on the ceramic structure. The surface area of the cathode aperture and the flow rate of the solution influence on the detection limits (DLs) of Zn and Cd.

Originality/value
Constructed ceramic structures were able to excite elements and their laboratory-size systems. During the experiments, Zn and Cd were detected with DLs 0.024 and 0.053 mg/L, respectively.

Authors: Wen Jun , Kozak Metin , Yang Shaohua , Liu Fang 
Published: May 2020

PurposeThe 2019 novel coronavirus (COVID-19) outbreak is projected to have adverse consequences on the global tourism and hospitality industry. This paper aims to examine how the outbreak may alter Chinese tourists’ lifestyle choices, travel behaviour and tourism preferences in the short and long term.Design/methodology/approachThis paper is based on the synthesis of news broadcasted by several media outlets to be supported by an overview of the related literature on tourism marketing, tourism management and tourist behaviour. The authors’ experiences investigating trends in tourism and hospitality at the local and international level have also contributed to the study.FindingsThis paper predicts that COVID-19 will likely affect Chinese travellers’ consumption patterns, such as the growing popularity of free and independent travel, luxury trips and health and wellness tourism. New forms of tourism including slow tourism and smart tourism may also drive future tourism activities. Such changes are likely to force businesses to reconsider their service designs and distribution channels.Research limitations/implicationsWhile Chinese and other potential visitors rethink how they travel, professionals, too, should reflect upon how to bring positive or negative changes to the tourism industry following this pandemic. Subsequent research should also consider how to mitigate the effects of similar public health crises in the future.Practical implicationsRecommendations for industry practitioners and policymakers focus on tailoring travel arrangements to tourists’ backgrounds. The suggestions may help to alleviate outbreak-related stress, offer travellers newly enriching experiences and partially mitigate the effects of COVID-19 on the tourism and hospitality industry. These recommendations can also apply more broadly to global tourist markets.Social implicationsThe COVID-19 outbreak has already brought significant impacts to nearly every society and industry. Tourism scholars and practitioners should carefully consider this tragedy and how it may inform industry and social practices. This and other public health crises represent sterling opportunities to view the industry holistically in terms of its effects on the environment, climate and travellers themselves.Originality/valueThis paper presumably represents a frontier study, critically examining the possible impacts of COVID-19 on Chinese travellers’ consumption patterns and how the tourism and hospitality industry may respond to such changes in the future.

Published: May 2020

Purpose
This paper aims to examine an investigation of high-pressure coolant (HPC) drilling process with regard to experimental models of output parameters, effect of input parameters on output parameters and simultaneous optimization of the output parameters.

Design/methodology/approach
Experimental plan was designed using response surface method and experiments were conducted on HPC drilling set up. Measurements for output parameters were carried out and mathematical models were obtained. Multi response optimization using a composite desirability function approach was used to obtain optimum values of input parameters for simultaneous optimization of output parameters.

Findings
Optimal value of input parameters for optimization of HPC drilling process were obtained as; coolant pressure: 21 bar, spindle speed: 3,970 rpm, feed rate: 0.084 mm/rev and peck depth: 5.50 mm. The composite desirability obtained is 0.9412, which indicates that the performance of HPC drilling process was significantly optimized. Developed mathematical models of the output parameters accurately represent the entire design space under investigation.

Originality/value
This is the first study that involves variation of higher coolant pressure and investigation of HPC drilling process using response surface methodology and multi response optimization technique with desirability function.
Idea Paper: Tracking the distribution of accretive reef communities across the Kuroshio region
Authors: Denis Vianney , Fan Tung‐Yung , Hsiao Wanchien Victoria , Hwang Sung‐Jin , Lin Yuting Vicky , Nozawa Yoko 
Published: May 2020

AbstractIn line with contemporary changes in oceanic conditions, reef communities could be declining at the equator and expanding polewards, having previously happened in the past. Yet, some tropical organisms are now decimated at their distributional cores and observed beyond their inferred range limits. However, it remains unclear if this is happening at the community scale, especially due to the challenges of collecting quantitative and comparable data across latitudes. Here, we propose that monitoring sentinel plots via photogrammetry could help to assess abiding changes in benthic communities and trajectories of reef‐building populations across the Kuroshio region. We think that as oceans are becoming warmer, accretive reef communities may shift their distribution northwards which may be primarily due to a change in the relative biomass‐abundance of resident taxa. Consistent trends among latitudes will resolve the possibility of contraction or expansion of accretive reef communities, providing further insight into the variety of responses and dynamics observed across latitudes in the context of the Anthropocene.
Significant Differences in PostMortem Heart Weight Before and After Dissection Using the Short‐Axis Dissecting Method

Published: May 2020

AbstractCorrectly assessing heart weight can be critical at postmortem examination. The current international guidelines advocate using the short‐axis method in dissecting the heart and the heart weighed when the blood is emptied. However, it did not specify at what point the heart should be weighed or how the blood should be emptied. This study compared heart weights at three different time points during the heart examination (immediately after dissecting out of the pericardial sac with blood still in chambers, blood washed/removed from heart chambers without the heart opened, and the heart completely opened, blood emptied, and pad dried). This was to illustrate the variation in measurement and potential errors when the heart is weighed at different time of dissection. The results show that there were statistical and clinical significant differences between the heart weights at each weighing points. We recommend the heart to be completely dissected with any blood and residual washing/rinsing water emptied before being weighed. Although performed in this study, the effect of pad drying the heart on heart weight was not explored and was a limitation in this study.

Published: May 2020

AbstractOwing to their potential applications, as well as their structural diversity, the discovery of novel secondary metabolites from insect‐associated fungi has been of interest to researchers in recent years. The aim of this study was therefore to estimate the diversity of fungi associated with fungus‐growing termites and bioprospecting these for potential secondary metabolites. In total, 18 fungal species were isolated and described from the gut and comb of Macrotermes barneyi based on 18S ribosomal DNA gene sequence analysis. Antimicrobial activity assays were carried out on all the known fungi, and nine isolates were recorded as active against pathogenic fungi. Xylaria escharoidea, the best performing isolate, was grown at laboratory scale and 4,8‐dihydroxy‐3,4‐dihydronaphthalen‐1(2H) was isolated and characterized. The minimum inhibitory concentration of this isolated compound against tested pathogenic organisms was found to be 6.25 μg. In addition, molecular docking studies have revealed that 4,8‐dihydroxy‐3,4‐dihydronaphthalen‐1(2H) is a prominent antibacterial agent with a marked interaction with key residues on protein A (agrAC) that regulates the accessory gene. The findings of this study support the drug discovery of antimicrobial properties in insect‐associated fungi, which may lead to novel secondary metabolites.

Published: May 2020

AbstractThe technique for order performance by similarity to ideal solution (TOPSIS) method was used to select the optimum point of power and time of ultrasound and baking temperature of eggless cake production. The effect of ultrasound power and baking time on the mass‐transfer parameters such as moisture diffusion and the activation energy was assessed. The sonication treatment increased the viscosity of the eggless cake batter (25% in consistency coefficient and 24% in apparent viscosity). The minimum batter density was observed at 60% intensity for 30 or 60 s of sonication (1.0253 and 1.027 g/cm3). This condition also increased the eggless cake volume and springiness. In contrast, the crumb fractal dimension, hardness, gumminess, cohesiveness, and chewiness of the eggless cake decreased (1.65, 29, 39, 39, and 33%, respectively). The moisture diffusion during baking at 160, 180, and 200 °C and different ultrasound intensities were studied. The baking temperature of 200 °C and the intensity of 60% had the maximum effect on increasing the moisture diffusivity. Arrhenius equation showed the activation energy varied from 21.38 to 22.95 kJ/mol. The optimum quality of the eggless cake resulted from a combination of 60% intensity and 60 s of sonication and the baking temperature of 180 °C.Practical ApplicationSome vegetarians do not consume eggs and egg‐based products; therefore it is important to produce egg‐free food options. Also, considering that eggs are one of the most expensive raw materials in the production of various types of cakes and have a low shelf‐life, in this study, the effects of sonication on the quality characteristics of an eggless cake has been studied.
