Determination of maximum power point from photovoltaic system using genetic algorithm
Authors: Najdoska Angela , Cvetkovski Goga Vladimir 
Published: April 2022

Purpose
The purpose of this paper is to present a novel approach to the determination of the maximum power point (MPP) in the photovoltaic system using genetic algorithm (GA). The optimization is realised on two types of photovoltaic (PV) modules: monocrystalline and polycrystalline solar modules, with the same rated peak power (400 Wp) but different electrical output data.

Design/methodology/approach
The proposed algorithm is a nature-based algorithm that uses genetic operators such as reproduction, crossover and mutation to realise the search through the investigated area of solutions. To determine the MPP of the PV modules, a two-diode model of a PV cell is used. Based on the input electrical data for the analysed PV module, as well as the mathematical model of the PV, the algorithm can estimate the current and voltage at the MPP for given solar irradiation and cell temperature. The analysis is made for several different irradiations, but in work, the results are presented for irradiations of: 100, 500 and 1,000 W/m2 and cell temperatures of 0, 25 and 40 °C.

Findings
From the presented results and performed analysis, it can be concluded that GA gives adequate results for both modules and for all working conditions. From the obtained results, it can be concluded that the optimization algorithm performs better when applied to the monocrystalline module works better especially in conditions with larger cell temperature, in comparison with the performance of the optimization algorithm applied to the polycrystalline module. On the other hand, the optimization algorithm applied to the polycrystalline module works better for the other working scenarios with smaller cell temperatures.

Practical implications
From the performed analysis, it can be concluded that the use GA as an optimization tool for the determination of the MPP can be successfully implemented. In addition, to improve the overall performance of the PV system, it is also necessary to forecast the weather conditions of the location where the PV system would be installed to forecast the cell temperature and the solar irradiation. This is necessary to choose the right PV module and inverter for the given location.

Originality/value
An optimization technique using GA as an optimization tool has been developed and successfully applied in the determination of the MPP for a PV system. The results are compared with the analytically determined values as well as with the values given by the producer, and they show good agreement.

Published: April 2022

PurposeThis paper aims to examine how evangelical teachers’ religious identities influence their interpretation and teaching of texts in high school English Language Arts classrooms. Further, this paper examines how evangelical teachers make choices about how to balance the demands of their religious and teacher identities as they interact with texts in their own classrooms.Design/methodology/approachUsing Derridean deconstruction of the concept of ethical decision-making, the author uses critical discourse analysis to examine a conversation between two evangelical teachers as they talk about the tensions they feel as they teachThe Cruciblewith their high school–aged students.FindingsThe findings show evangelical teachers’ religious and teaching identities were in tension across three themes: literary analytic frameworks, authorial intent and eternal truths and evangelism and fellowship.Originality/valueBy highlighting how evangelical teachers’ religious and teaching identities influence their classroom decisions, teaching practices and textual interpretations, this study offers another pathway through which teacher educators and researchers might examine the connection between teachers’ religious and teaching identities with the intent to invite more complexity into literary analysis.
Housing market price movements under tech industry expansion during COVID-19
Authors: Jiao Junfeng , Bhat Mira R. , Azimian Amin , Mandalapu Akhil , Farahi Arya 
Published: April 2022

Purpose
This study aims to analyze the impact of technology-based corporation relocation on housing price indices during COVID-19 within the metropolitan areas of Austin, Texas and Seattle/Bellevue, Washington.The corporations under observation were Tesla and Amazon, respectively. The analysis intends to understand economic drivers behind the housing market and the radius of its effect while including fixed and random effects.

Design/methodology/approach
This study used a difference-in-difference (DID) method to evaluate changes in housing price index near and further away from Tesla’s and Amazon’s new corporate locations. The DID method allows for the capture of unique regional characteristics, as it requires a treatment and control group: housing price index and 5-mile and 10-mile search radii centered from the new corporate location.

Findings
The results indicated that corporate relocation announcements had a positive effect on housing price index post-pandemic. Specifically, the effect of Tesla’s relocation in Austin on the housing price index was not concentrated near the relocation site, but beyond the 5- and 10-mile radii. For Seattle/Bellevue, the effect of Amazon’s relocation announcement on housing price index was concentrated near the relocation site as well as beyond a 10-mile radius. Interestingly, these findings suggest housing markets incorporate speculation of prospective economic expansion linked with a corporate relocation.

Originality/value
Previous literature assessed COVID-19 housing market conditions and the economic effects of corporate relocation separately, whereas this study analyzed the housing price effects of corporate relocation during COVID-19. The DID method includes spatial and temporal analyses that allow for the impact of housing price to be observed across specified radii rather than a city-wide impact analysis.

Optimization lubrication performance of journal bearings with microtexture
Authors: Wang Lili , Zhang Wei , Zhao Xingtang , Ge Xue 
Published: April 2022

Purpose
Researchers have not reached an agreement on which biomimetic shape has the best lubrication performance. This paper aims to study the influence of microtexture size, shape and direction on bearing capacity, end leakage, friction coefficient and wear of oil film.

Design/methodology/approach
Different oil film thickness equations considering the microtexture of bearing surface are gained. The two-dimensional finite difference equation and the calculation equation of wear are established.

Findings
The theoretical research shows that the wear value and the wear ratio when long side is perpendicular to the axial direction of the bearing are generally lower than when the long axis is parallel to the axial direction of bearing. The theoretical and experimental results show that the appropriate microtexture shape, such as circular dimple, crescent-shaped dimple, triangular dimple and fish-shaped dimple can improve effectively the lubrication performance of journal bearing and reduce the friction coefficient.

Originality/value
The research has great significance to reduce friction and improve the wear resistance of equipment.

PurposeThe study aims to understand how dynamic capabilities (DCs) contribute to business model innovation (BMI) in sustainable family farming. The agrifood sector has been seeking solutions for the development of agroecological markets. Thus, the authors have analyzed the challenges imposed to innovation and sustainability strategic management and the value proposition to sustain the business over the years.Design/methodology/approachConsidering the complexity of organizations and through an exploratory multiple case study of initiatives identified in the Organic Fair of Curitiba’s Passeio Público, it was possible to analyze the evolution of the business models (BMs) and the fair itself. Furthermore, it was possible to identify the DCs within the influence of agroecosystem elements on the innovation development.FindingsAnalyzing each case individually, the authors understood the different dimensions of the evolution of BMs considering the organizational complexity. The authors conclude that the balance between organizational practices and changes in the environment, engagement and learning plays a significant role in the developing competitive advantage. The same applies to the patterns that precede the development of DCs and BMs.Originality/valueThe article investigates innovation in agroecological BMs from a dynamic capability perspective. The agroecological BM is a subject that is still little discussed in the literature. In addition, the authors chose a context that includes socioenvironmental aspects and a few specificities of family farming in Brazil.

Authors: Fan Yunfei , Zhang Yilian , Jie Huang , Yue Tang , Bi Qingzhen , Wang Yuhan 
Published: April 2022

Purpose
This paper aims to propose a novel model and calibration method to improve the absolute positioning accuracy of a robotic drilling system with secondary encoders and additional axis.

Design/methodology/approach
The enhanced rigid-flexible coupling model is developed by considering both kinematic parameters and link flexibility. The kinematic errors of the robot and the additional axis are considered with a model containing 27 parameters. The elastic deformation errors of the robot under self-weight of links and end-effector are estimated with a flexible link model. For calibration, an effective comprehensive calibration method is developed by further considering the coordinate systems parameters of the drilling system and using a two-step process constrained Levenberg–Marquardt identification method.

Findings
Experiments are performed on the robotic drilling system that contains a KUKA KR500 R2830 industrial robot and an additional lifting axis with a laser tracker. The results show that the maximum error and mean error are reduced to 0.311 and 0.136 mm, respectively, which verify the effectiveness of the model and the calibration method.

Originality/value
A novel enhanced rigid-flexible coupling model and a practical comprehensive calibration method are proposed and verified. The experiments results indicate that the absolute positioning accuracy of the system in a large workspace is greatly improved, which is conducive to the application of industrial robots in the field of aerospace assembly.

Expatriates' adjustment and performance in risky environments: the role of organizational support and rewards, risk propensity and resilience
Authors: Sarfraz Muhammad , Nisar Qasim Ali , Raza Ali 
Published: April 2022

PurposeDrawing upon the social exchange and psychological capital literature and applying a multilevel perspective, this paper examines how personal and organizational factors contribute to expatriates' adjustment and performance of international assignments in a terrorism-induced risky environment.Design/methodology/approachData were collected using a non-probability sampling approach (e.g. purposive and subsequent snowball sampling). The authors tested the hypotheses using survey data of 138 expatriates with current international assignments in Pakistan.FindingsExpatriates' perceived organizational and risk-taking propensity influences their performance through improved adjustment. Moderating effects suggest that an individual's satisfaction with the received organizational rewards strengthens the risk-taking propensity to adjustment relationship; resilience strengthens the adjustment to performance relationship.Originality/valueThis study extends existing expatriation literature by focusing on a specific type of risk factor pertinent to international assignments, i.e. terrorism. Integrating individual and organizational factors that influence adjustment and subsequent performance provides a clear picture rather if such factors are operationalized separately in the terrorism-induced risky environment context.

Authors: Fauzi Muhammad Ashraf 
Published: April 2022

PurposeThe purpose of this paper is to systematically review knowledge hiding (KH) behaviors in the team context. KH behavior is regarded as unethical and antisocial behavior, detrimental to team development and performance. The nature of its existence should not be allowed in team activities.Design/methodology/approachApplying a systematic literature review, this study investigated 39 related quantitative studies on KH behavior of employees in team and group contexts. This study discusses the fundamental concept of KH, analyzes current research findings, identifies relevant gaps in the team and group context and sheds light on future direction.FindingsFindings observed that the KH phenomena had gained the interest of scholars since the year 2010. Five main research streams identified in this systematic review are role of leadership, team creativity and innovation, underlying theory, multilevel modeling and KH scale.Research limitations/implicationsThe value of this paper is subjected to the specific notion of KH in team background where knowledge sharing should have been promoted instead of KH. This systematic review serves as insight and recognition on the importance of mitigating KH in team. Existing current literature, future research work and trends of KH in the organization may benefit from this new and anticipated behavior within the knowledge management field.Originality/valueTo the best of the authors’ knowledge, this review is the first to review KH behavior in the team context.
Absorptive roots drive a larger microbial carbon pump efficacy than transport roots in alpine coniferous forests
Authors: Wang Qitong , Zhang Ziliang , Zhu Xiaomin , Liu Zhanfeng , Li Na , Xiao Juan , Liu Qing , Yin Huajun 
Published: April 2022

Abstract

Root activity creates a unique microbial hotspot in the rhizosphere and profoundly regulates soil carbon (C) dynamics, but empirical assessments of the soil microbial carbon pump (MCP, the iterative accumulation of necromass after microbial anabolism) and associated ecological consequences on soil C storage based on insight of the rhizosphere are still neglected, especially for different root functional modules.

We assessed the soil MCP efficacy (i.e. the contribution of microbial necromass to SOC) by investigating the divergent contribution of microbial necromass based on amino sugar extrapolations to soil organic C (SOC) in the rhizosphere of two root functional modules (i.e. absorptive roots and transport roots) and the bulk soil in an alpine coniferous forest.

The results showed that the MCP efficacy in both rhizosphere and bulk soil was more than 50%, suggesting that microbial necromass plays a key role in SOC formation. More importantly, absorptive roots drove a greater rhizosphere MCP efficacy (56%) than transport roots (51%).

Synthesis. These observations suggest that the microbial necromass is a major contributor to SOC storage in both rhizosphere and bulk soil in alpine coniferous forests. The magnitude of the contribution of microbial necromass to rhizosphere SOC depends on root functional differentiation. Our study provides novel and direct empirical evidence for the active soil MCP functions in SOC sequestration from the perspective of the rhizosphere.
