Abstract

Purpose

The purpose of this paper is to present a vision-based method for the kinematic calibration of a six-degrees-of-freedom parallel robot named Hexa using only one Universal Serial Bus (USB) camera and a chess pattern installed on the robot's mobile platform. Such an approach avoids using any internal sensors or complex three-dimensional measurement systems to obtain the pose (position/orientation) of the robot's end-effector or the joint coordinates.

Design/methodology/approach

The setup of the proposed method is very simple; only one USB camera connected to a laptop computer is needed and no contact with the robot is necessary during the calibration procedure. For camera modeling, a pinhole model is used; it is then modified by considering some distortion coefficients. Intrinsic and extrinsic parameters and the distortion coefficients are found by an offline minimization algorithm. The chess pattern makes image corner detection very straightforward; this detection leads to finding the camera and then the kinematic parameters. To carry out the calibration procedure, several trajectories are run (the results of two of them are presented here) and sufficient specifications of the poses (positions/orientations) are calculated to find the kinematic parameters of the robot. Experimental results obtained when applying the calibration procedure on a Hexa parallel robot show that vision-based kinematic calibration yields enhanced and efficient positioning accuracy. After successful calibration and addition of an appropriate control scheme, the robot has been considered as a color-painting prototype robot to serve in relevant industries.

Findings

Experimental results obtained when applying the calibration procedure on a Hexa parallel robot show that vision-based kinematic calibration yields enhanced and efficient positioning accuracy.

Originality/value

The enhanced results show the advantages of this method in comparison with the previous calibration methods.

The purpose of this paper is standardize and provide a multidimensional measure for assessing human resources competencies (HRCs) scale.

Abstract

Purpose

The purpose of this paper is standardize and provide a multidimensional measure for assessing human resources competencies (HRCs) scale.

Design/methodology/approach

The data collected in this study were 2018 from the 234 people selected from 603 managers and experts in human resources of selected firms existing in the Yazd Industrial Town randomly. Based on the model of HRCs designed by Ulrich et al. (2008), a questionnaire was developed to assess HRCs. Internal consistency and split-half methods were used to obtain the reliability of the instrument. Content validity and construct validity of the instrument were also assessed through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA).

Findings

This paper elucidates a key scale for assessing HRCs including three dimensions: knowledge business, functional expertise and managing change. Also, results revealed that two items were then dropped from the questionnaire as they were unreliable, and a final 31 items were extracted to form the scale for assessing HRCs. The coefficients for Cronbach’s α and split-half were 0.963 and 0.947, respectively. In EFA, Kaiser-Meyer-Olkin test yielded optimal 0.962, and Bartlett’s test was statistically significant. Additionally, three factors with eigenvalues higher than 1 explained 63% of the total variance. Hence, CFA confirmed the results from EFA too. Moreover, the model proved to enjoy a good fit.

Practical implications

The scale is useful for both researchers and practitioners. Also, the scale provides researchers with a sought-after conceptualization of HRCs.

Originality/value

Consequently, considering that the validity and reliability indices of HRCs were estimated to be desirable, the authors believe that the developed questionnaire can be used as an appropriate scale for measuring HRCs in future research.

Abstract

Purpose

Blockchain is an emerging digital technology proposed and trialled among different built environment professions. The technology has been proposed to introduce transparency, security and trust in property transactions. Despite this proposition, few studies have analysed the barriers and prospects in property valuation, especially in markets plagued by low transparency and a lack of stakeholder trust. Using Nigeria as a case study, this study assesses the barriers and prospects for adopting blockchain technology in property valuation.

Design/methodology/approach

Data was collected from 180 valuers practising in Nigeria through an online survey, and the data was analysed using mean score ranking and the chi-square (χ2) test of independence.

Findings

Firstly, there was a low awareness of the application of blockchain technology and an association between the number of valuation jobs executed annually and awareness of the application of blockchain technology. The most important barriers revolved around the knowledge, technical know-how of blockchain and the cost of implementing such technology. The prospects for blockchain are very high as all identified prospects were considered important, with transparency being the most crucial factor for its adoption, followed by the monitoring activities in real time and the permanence in storing records.

Research limitations/implications

This study's implications lie in the potential benefit of transparency identified for blockchain, which could act as a tool to introduce transparency into valuation industries that battle key issues surrounding transparency and trust. Furthermore, this study can be utilised by policymakers and property industry players in mapping strategies to adopt the beneficial use of blockchain as one among the suite of proptech tools disrupting the property valuation scene, in their practice. This also presents an opportunity to draw upon insights from this study to better prepare for using blockchain in property valuation.

Originality/value

This study appears to be the first to empirically assess barriers and prospects for blockchain in property valuation practice. It contributes to the literature by identifying key factors that will deter and/or promote the application of blockchain, an emerging and disruptive digital technology.

Abstract

Purpose

The purpose of this paper is to systematically review e-lending research studies in the digital library domain to identify their subjects, existing research gap and their research methods.

Design/methodology/approach

This is a systematic review. Through several stages of searching in related databases, 30 research works including journal and conference research papers, theses and dissertations, research and technical reports were identified and reviewed based on the guidelines of systematic review protocols.

Findings

It was found that research in e-lending domain is growing, and the subject will receive greater attention in the near future. Studies were in the following four categories: e-books (specifications, creation and software and viewpoints), business models, e-book status in libraries and copyright issues, e-book lending and inter-library loan. Some research gaps were identified including e-lending domain, business models and legislation. Little has been done with qualitative and mixed approaches in terms of research methods. Moreover, findings showed that this area has received less attention in developing countries.

Originality/value

This is the first review of the e-lending domain in digital libraries. It identifies the key works related to e-lending, categorizes them, provides an overview and identifies emerging research issues.

Abstract

Purpose

Fundamental literature exists on the employment of diverse information technology (IT) innovations relied on utility computing, a little experimental literature exists on cloud computing adoption by medium enterprises. So, this essay aims to analyze the determinants of the acceptance of cloud computing in medium-sized organizations. It also targets the impact of cloud-depended services on employers' talent management in the analysis areas of research reports, hypotheses and frameworks used by them.

Design/methodology/approach

Cloud computing is a novel and notable development in the network application field with a novel IT viewpoint. The present investigation aims to assist and enrich the scientific argument regarding the phenomenon nominated cloud computing from a managerial perspective. A quantitative study design was utilized to gather and analyze the data. In total, 345 employees from different medium enterprises reported their perspectives via an online survey. Partial least squares was used to evaluate the model of the study. The investigation was performed from April 2020 to November 2020.

Findings

As expected, the empirical analysis results revealed that cloud computing adaption drivers positively and significantly associated with talent management. The results showed that organizational level is the most important factor in the effectiveness of talent management. Further, this study established a cloud strategy that moderates the relationships between cloud computing adaption drivers and talent management. As a general result, organization managers must implement cloud computing to improve organizational performance, reduce costs, enhance organizational innovation and reduce repetitive work. So, international trade facilitates and helps the country's economy.

Research limitations/implications

There are still some drawbacks of this analysis that require addressing the findings. Initially, the authors gathered a country's data. Second, by considering multiple significant structures from four aspects, they established the study model. Third, utilizing one-time cross-sectional data, the suggested model was evaluated. As a proposal, future researchers could investigate cloud computing adoption drivers' outcomes within other organizations.

Originality/value

This research presents a straightforward and easy model for understanding the cloud's effect on employee talent management. By systematizing the unrelated studies on the subject and organizing those contributions into strong managerial literature paradigms, such an aim has been accomplished.

Abstract

Purpose

Nowadays, communications, products, services and costs are customized through the internet technology. The main theory to continue competitiveness in the organizations is customer relationship management (CRM). CRM enables organizations to efficiently interact with customers and gather, store and examine their data for providing a complete view of them. On the other hand, the subject of cloud computing has increasingly become the bridge for the success of the CRM implementation. Therefore, this study aims to investigate the impact of cloud computing (new cloud facility, knowledge of information technology (IT), cloud security and cost) on the success of CRM systems.

Design/methodology/approach

The model and the questioners-based data are analyzed using the Smart PLS 3.0. The data were gathered based on 80 employees of three main agricultural companies in Iran.

Findings

The obtained results have indicated that all of the considered factors, new cloud facilities, knowledge of IT, cloud security and cost, play an important role in CRM systems’ success. Also, the evaluation and examination of the consistency and validity of the model are performed through the structural equation model.

Research limitations/implications

First, the authors have conducted a study in a single region. It cannot be guaranteed that the results can be generalized to other regions. Second, for this cross-sectional study, the research design was conducted that showed constant relationships between variables. The research done for this study is cross-sectional. Third, because of time and financial restrictions, the authors have gathered data using a sample from a single location.

Originality/value

Proposing a new model for investigating of the impact of cloud computing (new cloud facility, knowledge of Information Technology (IT), cloud security and cost) on the success of CRM systems is the main originality of this paper.

Abstract

Purpose

Garlic supplementation may be inversely contributed to body weight and composition; however, previous results have been inconsistent. This study aims to evaluate the effect of garlic supplementation on body weight and composition using a systematic review and meta-analysis.

Design/methodology/approach

Online databases of PubMed, ISI Web of Science, Scopus and Google Scholar were searched up to January 2020. The random-effects model was used to calculate the effect sizes of the included studies. The risk of bias of included studies was assessed using the Cochrane collaboration’s tool. Besides, the NutriGrade scoring system was applied to judge the credibility of the evidence.

Findings

In total, 18 studies (with 1,250 participants) were included in the meta-analysis. The pooled analysis revealed that garlic supplementation has a significant increase in body weight [weighted mean difference (WMD) = 0.31 Kg, 95% CI: 0.09, 0.53 Kg, P = 0.005, n = 12 effect sizes]. Waist circumference (WC) does remarkably reduce [WMD = −1.28 cm, 95% CI: −2.08, −0.47 cm, P = 0.002, n = 4 effect size]. However, body mass index, body fat percent and fat-free mass do not dramatically change (P > 0.05). Notably, the pooled analyses on body weight and WC were sensitive to two included studies. NutriGrade’s score was rated low for this meta-analysis.

Originality/value

Although garlic supplementation could slightly increase weight and simultaneously might decrease WC, these associations were not strong enough to corroborate the findings. Also, other anthropometric indices do not significantly change. Further well-designed randomized clinical trial studies are needed to confirm the results.

Abstract

Purpose

This paper aims to explore the requirements of organizational knowledge management initiatives using requirements engineering techniques, identifying the optimal techniques configuration and serving as a management tool for knowledge engineers.

Design/methodology/approach

The method is selection attributes. Knowledge management enablers are characterized and mapped with the coverage capabilities of requirements engineering techniques, using the attributes of the elicited object and a box-plot analysis. The information is gathered from 280 references, 32 companies and 16 experts in requirements engineering.

Findings

Requirements of organizational knowledge management initiatives are got optimally by combining interviews, use cases, scenarios, laddering and focus group techniques. The requirements of structure and processes are more complex to identify, while culture requirements are the best covered.

Research limitations/implications

Knowledge management enablers are analyzed according to the current studies and comprehension of engineering techniques.

Practical implications

Knowledge engineers need to consider the coverage capabilities of engineering techniques to design an optimal requirement identification and meet the objectives of organizational knowledge acquisition initiatives. Requirement engineers can improve the requirements identification by a staged selection process.

Social implications

The requirements of knowledge management initiatives that impact the community can be identified and traced to ensure the knowledge objectives. Requirements related to culture and people, like shared values, beliefs, and behaviors, are also considered.

Originality/value

To the best of the authors’ knowledge, this is the first study about formal requirement identification of knowledge management initiatives in the organizational context, providing the optimal configuration. A novel staged process is proposed for requirements engineering techniques selection, analyzing the enablers at component level and identifying the attributes associated with the elicited object.

Abstract

Purpose

This study aims to investigate the impact of managerial narcissism and overconfidence on financial statements’ comparability. In other words, this paper seeks to answer the question of whether the personality characteristics of managers may affect the level of financial statements’ quality of commercial entities or not.

Design/methodology/approach

The research hypotheses are tested using a sample of 896 observations taken from the Tehran Stock Exchange and 245 observations from the Iraqi Stock Exchange during 2012 and 2018 using the multiple regression model based on the combined data technique.

Findings

The findings show that managerial narcissism is positively and significantly associated with Iran’s financial statement comparability. In contrast, Iraqi data articulate a negative association between these two variables. This paper finds that Chief Executive Officer overconfidence and financial statements’ comparability are negatively related in both countries. Following the market variation, the different findings suggest that institutional settings such as the general managerial style, adopting international accounting standards (now IFRS) leading to the extent of auditing market globally in Iraq and suffering from international sanctions in Iran, the governing business environment may play an allocative role in preparing financial statements.

Originality/value

The present research is the first research conducted in two emerging markets (Iran and Iraq) examining the relationship between managers’ narcissism and overconfidence and financial statements’ comparability. Therefore, the present research in this area can significantly contribute to the development of science and knowledge.
