Ultra-structural analysis and morphological changes during the differentiation of trophozoite to cyst inEntamoeba invadens
Authors: Singh Nishant , Naiyer Sarah , Bhattacharya Sudha 
Published: June 2020

AbstractEntamoeba Histolytica, a pathogenic parasite, is the causative organism of amoebiasis and uses human colon to complete its life cycle. It destroys intestinal tissue leading to invasive disease. Since it does not form cyst in culture medium, a reptilian parasiteEntamoeba invadensserves as the model system to study encystation. Detailed investigation on the mechanism of cyst formation, information on ultra-structural changes and cyst wall formation during encystation are still lacking inE. invadens. Here, we used electron microscopy to study the ultrastructural changes during cyst formation and showed that the increase in heterochromatin patches and deformation of nuclear shape were early events in encystation. These changes peaked at ~20h post induction, and normal nuclear morphology was restored by 72h. Two types of cellular structures were visible by 16h. One was densely stained and consisted of the cytoplasmic mass with clearly visible nucleus. The other consisted of membranous shells with large vacuoles and scant cytoplasm. The former structure developed into the mature cyst while the latter structure was lost after 20h, This study of ultra-structural changes during encystation inE. invadensopens up the possibilities for further investigation into the mechanisms involved in this novel process.

Published: June 2020

AbstractUbiquilin proteins (UBQLNs) are involved in diverse cellular processes like ERAD (endoplasmic reticulum associated degradation), autophagy, apoptosis and epithelial to mesenchymal transition. UBQLNs interact with a variety of substrates, including cell surface receptors, transcription factor regulators, proteasomal machinery proteins, and transmembrane proteins. Additionally, previous work from our lab shows that UBQLN1 interacts with IGFR family members (IGF1R, IGF2R, INSR) and this interaction regulates the activity and proteostasis of IGFR family members. Here, we examined regulation of UBQLN1 with Epidermal Growth Factor Receptor (EGFR) in lung adenocarcinoma cells. Loss of UBQLN1 occurs at high frequency in human lung cancer patient samples and we have shown that loss of UBQLN1 is capable altering processes involved in cell proliferation, migration, invasion and epithelial to mesenchymal transition in lung adenocarcinoma cell lines. Here, we present data that loss of UBQLN1 resulted in increased turnover of total EGFR, whilst increasing the relative amount of active EGFR in lung adenocarcinoma cells, especially in the presence of its ligand EGF. Furthermore, loss of UBQLN1 led to a more invasive cell phenotype as manifested by increased proliferation, migration and speed of movement of these lung adenocarcinoma cells. Taken together, UBQLN1 regulates expression and stability of IGFRs and EGFR, members of the receptor tyrosine kinase family of proteins in lung cancer cells.

Published: June 2020

PurposeThe main objective of the present study is to assess the potential impact of readability of financial statement notes on the auditor's report lag, audit fees and going concern opinion (GCO).Design/methodology/approachThe statistical population of this study includes all listed firms on the Tehran Stock Exchange (TSE) for the period of 2012–2017. The systematic elimination method is used for sampling and multiple regression and EViews software are used for testing the hypothesis models.FindingsThe obtained results show that there is a significant and positive relationship between audit report lags and readability of financial statements. Moreover, it is also revealed that readability of financial statements is positively associated with audit fees. Furthermore, the findings suggest a negative correlation between readability indexes and issuing GCOs, denoting hard-to-read statements is considered as a risk factor by auditors. Finally, the observations of our robustness tests suggest that the association between audit report lag and readability of financial statements is robust.Originality/valueThis is the first conducted investigation concerning auditor's response to the readability of financial statement notes in TSE. The outcome of current paper may pave the way for revising and developing Iranian accounting standards in order to give a fairer and clearer picture of financial reports.
Student perspectives on employability development in higher education in South Africa
Authors: Pitan Oluyomi Susan , Muller Colette 
Published: June 2020

PurposeThis study responds to identified challenges of poor work-readiness of many graduates and the inadequate relation between education and work. Through students' perspectives, the study examines the extent to which selected South African universities are supporting their students in developing employability skills and the influence of such employability support on students' enhanced employability.Design/methodology/approachThrough purposive sampling, information was obtained from a sample of 402 final year students at two universities in South Africa. After an exploratory factor analysis, 34 of the 35 items on the questionnaire successfully loaded for further analysis under seven components.FindingsSouth African universities that were analysed are adequately engaging their students with two of the six employability development opportunities (EDOs), while students' engagement with the other four is only to a fair extent. EDOs are found to jointly influence students' employability. The curriculum has the highest influence, followed by personal development planning, career development learning and work experience. Real-world activities and extracurricular activities were not found to influence students' self-perceived employability.Originality/valueBeyond identifying skills that graduates are expected to possess, which dominate the discussion and debate on graduate employability, this study elucidates the role of universities in providing support structures – EDOs – that enable students to establish an appropriate connection between theory and practice. It provides insight into the employability potential of South African universities and increases the universities' awareness of what they can do to ensure the production of work-ready graduates.
Educating researchers in the metadiscipline of foresight
Authors: Kahan James P. 
Published: June 2020

Purpose
The science of Foresight differs from the commonplace notion of what a science is because it is a metadiscipline – a logical type of science higher than the logical type of disciplinary sciences. It is practical, uses transdisciplinary processes that combine scientific disciplines and often examines counterfactuals in a scientific manner. This study aims to demonstrate that Foresight is a science, by presenting a number of best practices and potential innovations in higher education that could facilitate obtaining skills for Foresight science.

Design/methodology/approach
The methods of scientific education that have served us well in the past are inadequate for metadisciplinary sciences such as Foresight. The paper discusses what metadisciplinarity is, using a variety of examples, and distinguishes it from disciplines and ways of crossing disciplinary boundaries. Understanding the essential characteristics of Foresight as a metadisciplinary science leads to identifying current best practices and possible educational innovations in undergraduate education that will facilitate obtaining Foresight skills. Throughout the paper, examples are drawn from the education and professional experience of the author in the USA and Europe.

Findings
This paper demonstrates that Foresight is a science and presents a number of best practices and potential innovations in higher education that could facilitate obtaining skills for Foresight science. It identifies barriers to those innovations and approaches to overcome them.

Originality/value
This viewpoint paper clarifies the meaning of the terms interdisciplinarity, transdisciplinarity and metadisciplinarity to identify the essential characteristics of Foresight as a science. Then, it identifies and advocates needed changes in North American higher education to provide earlier and more efficient opportunities for Foresight researchers and users to obtain the skills they need.
It is not my job: exploring the disconnect between corporate security policies and actual security practices in SMEs
Authors: Sadok Moufida , Alter Steven , Bednar Peter 
Published: June 2020

Purpose
This paper aims to present empirical results exemplifying challenges related to information security faced by small and medium enterprises (SMEs). It uses guidelines based on work system theory (WST) to frame the results, thereby illustrating why the mere existence of corporate security policies or general security training often is insufficient for establishing and maintaining information security.

Design/methodology/approach
This research was designed to produce a better appreciation and understanding of potential issues or gaps in security practices in SMEs. The research team interviewed 187 employees of 39 SMEs in the UK. All of those employees had access to sensitive information. Gathering information through interviews (instead of formal security documentation) made it possible to assess security practices from employees’ point of view.

Findings
Corporate policies that highlight information security are often disconnected from actual work practices and routines and often do not receive high priority in everyday work practices. A vast majority of the interviewed employees are not involved in risk assessment or in the development of security practices. Security practices remain an illusory activity in their real-world contexts.

Research limitations/implications
This paper focuses only on closed-ended questions related to the following topics: awareness of existing security policy; information security practices and management and information security involvement.

Practical implications
The empirical findings show that corporate information security policies in SMEs often are insufficient for maintaining security unless those policies are integrated with visible and recognized work practices in work systems that use or produce sensitive information. The interpretation based on WST provides guidelines for enhancing information system security.

Originality/value
Beyond merely reporting empirical results, this research uses WST to interpret the results in a way that has direct implications for practitioners and for researchers.
Asian solo male travelling mobilities – an autoethnography
Authors: Tham Aaron 
Published: June 2020

Purpose
This study aims to unpack the notion of travelling mobilities from the perspectives of an Asian solo traveller using the context of the 2019 Rugby World Cup in Japan.

Design/methodology/approach
An autoethnography was used for this research, analysing reflective notes drafted on hand-written journals over the duration of six days over three host cities of the sporting event.

Findings
Asian solo men appear to be treated very differently from their Western counterparts and solo female tourists. In addition, engaging with a sport that is highly Western-centric exposes the liminal spaces of in-between. Being of Asian appearance and conversant in Japanese further blurred the travelling mobilities of being an unlikely sports fan, an impromptu translator, a presumed local resident and an unconventional wanderer.

Originality/value
These limitations notwithstanding, the research has contributed to the paucity of knowledge surrounding Asian solo male tourists and some aspects of their corresponding travelling mobilities. Such nuanced understanding then inform tourism and hospitality knowledge and practice of offering relevant experiences to such a market.
Factors impacting post-earthquake damage repair cost estimations
Authors: Kahandawa Ravindu , Domingo Niluka , Chawynski Gregory , Uma S.R. 
Published: June 2020

Purpose
Reconstruction processes after an earthquake require estimating repair costs to decide on whether to repair or rebuild. This requires an accurate post-earthquake cost estimation tool. Currently, there are no post-earthquake loss estimation models to estimate repair costs accurately. There are loss assessment tools available, namely, HAZUS, performance assessment calculation tool (PACT), seismic performance and loss assessment tool (SLAT) and seismic performance prediction tool, which have not been specifically used for post-earthquake repair cost estimation. This paper aims to focus on identifying factors that need to be considered when upgrading these tools for post-earthquake repair cost estimation.

Design/methodology/approach
The research was conducted as an exploratory study using a literature review, document analysis of the PACT, SLAT and HAZUS software and 18 semi-structured interviews.

Findings
The research identified information sources available for estimation and factors to be considered when developing estimations based on the information sources.

Research limitations/implications
The data was collected from professionals who were involved mostly in housing repair work in New Zealand. Therefore, impact of these repair work factors might vary in other forms of structures such as civil structures include bridges and the country as a result of varying construction details and standards.

Practical implications
The identified factors will be used to improve the loss estimation tools are such as PACT and HAZUS, as well as to develop a post-earthquake repair cost estimation tool.

Originality/value
Currently, the identified factors impacting post-earthquake damage repair cost estimations are not considered in loss estimation tools. Factors identified in this research will help to develop a more accurate cost estimation tool for post-earthquake repair work.

How is responsible leadership related to the three-component model of organisational commitment?
Authors: Haque Amlan , Fernando Mario , Caputi Peter 
Published: June 2020

PurposeThe increasing number of corporate scandals and averseness to employee commitment have brought the concept of responsible leadership (RL) to the forefront of organisational studies. Many studies have found that leadership practice is an antecedent of employees' organisational commitment. However, little attention has been devoted to exploring the newly evolved RL for its impact on employee commitment. This study examines the influence of RL on the three-component model of organisational commitment.Design/methodology/approachApplying the Social Identity Theory of Leadership (SITL), this study investigates the relationships between RL and the three-component model of organisational commitment. In particular, this study is framed to apply RL as a value-based leadership approach to examine its relationship on employees’ three types of organisational commitment such as affective, continuance and normative commitment. A web-based self-administered survey was applied to collect data targeting a sample of 200 full-time Australian employees.FindingsThe study results show that RL significantly effects all three components of organisational commitment. Both affective and normative commitments were significantly associated by RL compared to employees' continuance commitment.Originality/valueThe paper extends the knowledge regarding newly evolved concept of RL which explains the significance of employee commitment and, further it provides empirical evidence from the perspective of SITL. The main contribution in this paper comes from new knowledge about the associations among RL and the three-component model of organisational commitment.

Authors: Xu Guangcheng , Zhou Zhixiang 
Published: June 2020

PurposeThe purpose of this paper is to evaluate Chinese commercial banks efficiency based on different non-performing loans in the process. Moreover, we identified the difference among different types of banks (state-owned commercial banks, joint-stock commercial banks and city commercial banks) and different operation stages (deposit producing sub-stage, profit earning sub-stage and overall stage).Design/methodology/approachAssurance region (AR) restrictions are combined with a two-stage data envelopment analysis (DEA) model. The efficiency scores of 26 Chinese commercial banks (listed banks) are analyzed by a two-stage AR-DEA model in the study period of 2013–2017.FindingsThe results show that state-owned commercial banks had better performance than joint-stock commercial banks and city commercial banks over the five-year study period. The development of Internet finance has positive impact on deposit producing sub-stage and insignificant non-homogeneity existed among the different groups in the circumstances of considering different non-performing loans.Practical implicationsThe research findings provide practical insights that help bank managers find the defects in operation process, which need to be improved.Originality/valuePrevious studies viewed non-performing loans as an integrated whole variable. The paper divides non-performing loans into three categories based on the risk and investigates the effect of different types of loans on bank efficiency scores.
2D lidar to kinematic chain calibration using planar features of indoor scenes
Authors: Lourenço Bernardo , Madeira Tiago , Dias Paulo , Santos Vitor M. Ferreira , Oliveira Miguel 
Published: June 2020

Purpose2D laser rangefinders (LRFs) are commonly used sensors in the field of robotics, as they provide accurate range measurements with high angular resolution. These sensors can be coupled with mechanical units which, by granting an additional degree of freedom to the movement of the LRF, enable the 3D perception of a scene. To be successful, this reconstruction procedure requires to evaluate with high accuracy the extrinsic transformation between the LRF and the motorized system.Design/methodology/approachIn this work, a calibration procedure is proposed to evaluate this transformation. The method does not require a predefined marker (commonly used despite its numerous disadvantages), as it uses planar features in the point acquired clouds.FindingsQualitative inspections show that the proposed method reduces artifacts significantly, which typically appear in point clouds because of inaccurate calibrations. Furthermore, quantitative results and comparisons with a high-resolution 3D scanner demonstrate that the calibrated point cloud represents the geometries present in the scene with much higher accuracy than with the un-calibrated point cloud.Practical implicationsThe last key point of this work is the comparison of two laser scanners: the lemonbot (authors’) and a commercial FARO scanner. Despite being almost ten times cheaper, the laser scanner was able to achieve similar results in terms of geometric accuracy.Originality/valueThis work describes a novel calibration technique that is easy to implement and is able to achieve accurate results. One of its key features is the use of planes to calibrate the extrinsic transformation.

Authors: Li Kam-Cheong , Wong Billy Tak-Ming 
Published: June 2020

PurposeThis paper aims to present a review of case studies on the use of learning analytics in Science, Technology, Engineering, (Arts), and Mathematics (or STE[A]M) education. It covers the features and trends of learning analytics practices as revealed in case studies.Design/methodology/approachA total of 34 case studies published from 2013 to 2018 reporting relevant learning analytics practices were collected from Scopus and Google Scholar for analysis. The features and trends of practices were identified through a comparison of the first (2013–2015) and the second period (2016–2018).FindingsThe results showed an increasing adoption of learning analytics in STE(A)M education, particularly in the USA and European countries and at the tertiary level. More specific types of data have been collected for the learning analytics practices, and the data related to students’ learning processes has also been more frequently used. The types of STE(A)M learning practices have become more diversified, with technology enhancement features increasingly introduced. The outcomes of the case studies reflect the overall benefits of learning analytics and address the specific needs of STE(A)M education. There have also been fewer types of limitations encountered in the learning analytics practices over the years, with unknown correlation among variables, small sample size and limited data being the major types.Originality/valueThis study reveals the implementation of learning analytics in relation to the contexts and needs of STE(A)M education. The findings also suggest future work for examining the adoption of learning analytics to cope with the development of STE(A)M and, in particular, how the successful experience of learning analytics in other disciplines could be transferred to STE(A)M.
