Various PCR based methods have been described for the diagnosis of malaria, but most depend on the use of Plasmodium species-specific probes and primers; hence only the tested species are identified and there is limited available data on the true circulating species diversity. Sensitive diagnostic tools and platforms for their use are needed to detect Plasmodium species in both clinical cases and asymptomatic infections that contribute to disease transmission. We have been recently developed for the first time a novel high throughput ‘haemoprotobiome’ metabarcoded DNA sequencing method and applied it for the quantification of haemoprotozoan parasites (Theleria and Babesia) of livestock. Here, we describe a novel, high throughput method using an Illumina MiSeq platform to demonstrate the proportions of Plasmodium species in metabarcoded DNA samples derived from human malaria patients. Plasmodium falciparum and Plasmodium vivax positive control gDNA was used to prepare mock DNA pools of parasites to evaluate the detection threshold of the assay for each of the two species and to assess the accuracy of proportional quantification. We then applied the assay to malaria-positive human samples to show the species composition of Plasmodium communities in the Punjab province of Pakistan and in the Afghanistan-Pakistan tribal areas. The diagnostic performance of the deep amplicon sequencing method was compared to an immunochromatographic assay that is widely used in the region. Metabarcoded DNA sequencing showed better diagnostic performance, greatly increasing the estimated prevalence of Plasmodium infection. The next-generation sequencing method using metabarcoded DNA has potential applications in the diagnosis, surveillance, treatment, and control of Plasmodium infections, as well as to study the parasite biology.
Conservation of an Ancient Oxidation Response That Controls Archaeal Epigenetic Traits Through Chromatin Protein Networks

Published: October 2019

Epigenetic variants of the archaeonSulfolobus solfataricuscalled SARC have evolved heritable traits including extreme acid resistance, enhanced genome integrity and a conserved “SARC” transcriptome related to acid resistance. These traits appear to result from altered chromatin protein function related to the heritable hypomethylation of chromatin proteins Cren7 and Sso7D. To clarify how this might occur, ChIPseq and Affinity Purification Mass Spectrometry (AP-MS) were used to compare Cren7 and Sso7D genome binding sites and protein networks between lineages (wild type and SARC) and culture pH (pH 1 and 3). All SARC transcriptome loci were bound by these chromatin proteins but with invariant patterns indicating binding alone was insufficient to mediate the SARC traits. In contrast, chromosome association varied at other loci. Quantitative AP-MS was then used to identify protein interaction networks and these included transcription and DNA repair proteins implicated in the evolved heritable traits that varied in abundance between SARC and wild type strains. Protein networks included most of the S-adenosylmethionine (SAM) synthesis pathway including serine hydroxymethyltransferase (SHMT), whose abundance varied widely with culture pH. Because epigenetic marks are coupled to SAM pools and oxidative stress in eukaryotes, occurrence of a similar process was investigated here. Archaeal SAM pools were depleted by treatment with SAM pathway inhibitors, acid or oxidative stress and, like eukaryotes, levels were raised by vitamin B12 and methionine supplementation. We propose that in archaea, oxidation-induced SAM pool depletion acting through an SHMT sensor, drove chromatin protein hypomethylation and thereby protein network changes that established the evolved SARC epigenetic traits.

Significance Statement

Archaea and eukaryotes share many molecular processes, including chromatin-mediated epigenetic inheritance of traits. As with eukaryotes, archaeal protein complexes were formed between trait-related proteins and chromatin proteins, subject to chromatin protein methylation state. Oxidation-induced depletion of S-adenosylmethionine (SAM) pools likely resulted in chromatin protein hypomethylation. Subsequent chromatin enrichment of serine hydroxymethyltransferase as a response to oxidative stress could modulate methylation at specific genomic loci. The interplay between archaeal metabolism and chromatin appear consistent with patterns observed in eukaryotes and indicate the existence of an ancient oxidation signal transduction pathway controlling epigenetics.
Inference of population genetic structure from temporal samples of DNA
Authors: François Olivier , Liégeois Séverine , Demaille Benjamin , Jay Flora
Published: October 2019

The recent years have seen a growing number of studies investigating evolutionary questions using ancient DNA techniques and temporal samples of DNA. To address these questions, one of the most frequently-used algorithm is based on principal component analysis (PCA). When PCA is applied to temporal samples, the sample dates are, however, ignored during analysis, which could lead to some misinterpretations of the results. Here we introduce a new factor analysis (FA) method for which individual scores are corrected for the effect of allele frequency drift through time. Based on a diffusion approximation, our approach approximates allele frequency drift in a random mating population by a Brownian process. Exact solutions for estimates of corrected factors are obtained, and a fast estimation algorithm is presented. We compared data representations obtained from the FA method with PCA and with PC projections in simulations of divergence and admixture scenarios. Then we applied FA with correction for temporal drift to study the evolution of hepatitis C virus in a patient infected by multiple strains, and to describe the population structure of ancient European samples.
Dendrites with specialized glial attachments develop by retrograde extension using SAX-7 and GRDN-1
Authors: Cebul Elizabeth R. , McLachlan Ian G. , Heiman Maxwell G.
Published: October 2019

Dendrites develop elaborate morphologies in concert with surrounding glia, but the molecules that coordinate dendrite and glial morphogenesis are mostly unknown.C. elegansoffers a powerful model for identifying such factors. Previous work in this system examined dendrites and glia that develop within epithelia, similar to mammalian sense organs. Here, we focus on the neurons BAG and URX, which are not part of an epithelium but instead form membranous attachments to a single glial cell at the nose, reminiscent of dendrite-glia contacts in the mammalian brain. We show that these dendrites develop by retrograde extension, in which the nascent dendrite endings anchor to the presumptive nose and then extend by stretch during embryo elongation. Using forward genetic screens, we find that dendrite development requires the adhesion protein SAX-7/L1CAM and the cytoplasmic protein GRDN-1/CCDC88C to anchor dendrite endings at the nose. SAX-7 acts in neurons and glia, while GRDN-1 acts in glia to non-autonomously promote dendrite extension. Thus, this work shows how glial factors can help to shape dendrites, and identifies a novel molecular mechanism for dendrite growth by retrograde extension.

100 kV is investigated as the operating voltage for single-particle electron cryomicroscopy (cryoEM). Reducing the electron energy from the current standard of 300 or 200 keV offers both cost savings and potentially improved imaging. The latter follows from recent measurements of radiation damage to biological specimens by high-energy electrons, which show that at lower energies there is an increased amount of information available per unit damage. For frozen hydrated specimens around 300 Å in thickness, the predicted optimal electron energy for imaging is 100 keV. Currently available electron cryomicroscopes in the 100–120 keV range are not optimized for cryoEM as they lack both the spatially coherent illumination needed for the high defocus used in cryoEM and imaging detectors optimized for 100 keV electrons. To demonstrate the potential of imaging at 100 kV, the voltage of a standard, commercial 200 kV field-emission gun (FEG) microscope was reduced to 100 kV and a side-entry cryoholder was used. As high-efficiency, large-area cameras are not currently available for 100 keV electrons, a commercial hybrid pixel camera designed for X-ray detection was attached to the camera chamber and was used for low-dose data collection. Using this configuration, five single-particle specimens were imaged: hepatitis B virus capsid, bacterial 70S ribosome, catalase, DNA protection during starvation protein and haemoglobin, ranging in size from 4.5 MDa to 64 kDa with corresponding diameters from 320 to 72 Å. These five data sets were used to reconstruct 3D structures with resolutions between 8.4 and 3.4 Å. Based on this work, the practical advantages and current technological limitations to single-particle cryoEM at 100 keV are considered. These results are also discussed in the context of future microscope development towards the goal of rapid, simple and widely available structure determination of any purified biological specimen.

Authors: S. Syam Narayanan , R. Asad Ahmed , Varghese Jijo Philip , S. Gopinath , Paulraj Jedidiah , M. Muthukumar
Published: October 2019

Purpose

The purpose of this paper is to experimentally analyze the effect of wing shape of various insects of different species in a flapping micro aerial vehicle (MAV).

Design/methodology/approach

Six different wings are fabricated for the MAV configuration, which is restricted to the size of 15 cm length and width; all wings have different surface area and constant span length of 6 cm. The force is being measured with the help of a force-sensing resistor (FSR), and the coefficients of lift were calculated and compared.

Findings

This study shows that the wing “Tipula sp” has better value of lift than other insect wings, except for the negative angle of attacks. The wing “Aeshna multicolor” gives the better values of lift in negative angles of attack.

Practical implications

This paper lays the foundation for the development of flapping MAVs with the insect wings. This type of wing can be used for spying purpose in the military zone and also can be used to survey remote and dangerous places where humans cannot enter.

Originality/value

This paper covers all basic insect wing configurations of different species with exact mimics of the veins. As the experimental investigation was carried for different angle of attacks, velocities and flapping frequencies, this paper can be used as reference for future flapping wing MAV developers.
Modeling the critical barriers to implementation of AACSB accreditation in business schools
Authors: Kundu Goutam Kumar
Published: October 2019

Purpose

The purpose of this paper is to identify and model the key barriers to the issue of adoption and implementation of AACSB accreditation standards in business schools. Business school management can focus on removing the key barriers and implement accreditation standards and practices to improve the quality of programs offered by them.

Design/methodology/approach

The present study adopts the interpretive structural modeling (ISM) approach to develop a hierarchical-based model of the key barriers to implementation of Advance Collegiate Schools of Business (AACSB) accreditation standards. It also depicts the mutual relationships among the key barriers.

Findings

The paper has identified the key barriers and presented an integrated model using ISM. Business schools need to pay maximum attention to diagnose and overcome these hindrances for effective implementation of AACSB accreditation standards.

Research limitations/implications

The model is based on the experts’ opinions, which may be biased, influencing the final output of the structural model. The developed model is to help the business school management in understanding the significance of the barriers, to prioritize or eliminate the same for the implementation of accreditation standards.

Originality/value

The depiction of barriers in the form of an ISM-based model is a new effort in the area of business school accreditation. The results will be useful to understand the barriers and overcome these for successful implementation of AACSB accreditation standards in business schools.
Mutuality or mutual dependence in the psychological contract: a power perspective
Authors: Ali Haris
Published: October 2019

Purpose

There have been increasing calls to explore the psychological contract from the lens of power. By addressing this gap, the purpose of this paper is to investigate the assumption of mutuality in relation to power dynamics in the employment relationship.

Design/methodology/approach

A total of 43 in-depth interviews are conducted with 6 managerial and 37 non-managerial respondents in three major call center organizations in Pakistan. Template analysis is used to analyze the data.

Findings

By undermining the assumption of implicit mutuality, the analysis reveals indeterminacy, an issue that has been frequently underplayed in the psychological contract research. The results further suggest that – in reality – employability, flexibility and employee training do not promote mutuality to the extent that is theoretically assumed because of the employers’ manipulation of these issues in their own favor.

Research limitations/implications

The focus on call centers limits the generality of findings with further qualitative research needed in other industries to explore how power asymmetries impact upon mutuality in different working environments.

Practical implications

The research implications suggest the significance of timely and explicit communication in order to curtail indeterminacy in the employment relationship. This will not only reduce the development of breach perceptions among employees but will also reinforce their psychological contracts with the organization.

Originality/value

This research contributes by highlighting the significance of mutual dependence rather than mutuality in the psychological contract. The mutual dependence approach efficiently acknowledges the implications of power asymmetries which remain largely under-researched in the psychological contract theory.
Exploring the relationship of university students’ educational variables and the degree of their use of virtual social networks
Authors: Jalali Mansour , Bouyer Asgarali
Published: October 2019

Purpose

The purpose of this paper is to explore relationships among the university students’ educational variables and their educational variables concerning educational, cultural and social dimensions.

Design/methodology/approach

A questionnaire was developed and validated for analyzing the relationship between the amount of time spent for using social networks and different dimensions of educational quality. The sample participants in this study included 400 students who were selected from a total of 3,500 students in Eastern and Western Azerbaijan provinces at north-west of Iran in 2017. Finally, 342 of 400 questionnaires were considered for analyzing. The Pearson and Spearman correlation coefficients and multiple regression were used to analyze data.

Findings

The results proved that the highest correlation coefficient was related to social networks and education quality and the lowest correlation was related to social networks and cultural quality. The result of applying multiple regression proved that there is a linear relationship between the roles of using social networks in predicting students’ educational quality.

Originality/value

The role of academic and general social media in studying students’ educational quality at universities is still under researched. This situation provides a significant potential to explore on the effect of academic and general virtual social media in creating educational and cultural awareness among university’s students. The findings of the current study add to the existing literature by contributing to a better awareness of university student and applying appropriate strategies to conduct the education of students.
A cost-benefit analysis model for the retrofit of sustainable urban drainage systems towards improved flood risk mitigation
Authors: Oladunjoye Oluwayemi A. , Proverbs David G. , Collins Beck , Xiao Hong
Published: October 2019

Purpose

The Environment Agency estimates that one in six homes in England (approximately 5.2m properties) are at risk from flooding and 185,000 commercial properties are located in flood-prone areas. Further, an estimate of 10,000 new homes are built on flood plains yearly. The UK has witnessed a significant increase in flood events over the past 10 years. During this period, there has been growing research attention into measures to mitigate the effects of flooding, including the benefits of deploying sustainable urban drainage systems (SuDs) in new developments or as a retrofit. The purpose of this paper is to present the development of a cost-benefit analysis model for the retrofit of SuDs focusing on the potential for improved flood risk mitigation in the context of commercial properties.

Design/methodology/approach

A synthesis of flood risk management and SuDs literature is used to inform the development of a conceptual cost-benefit analysis model for the retrofit of SuDs and focusing on the potential for improved flood risk mitigation in the context of commercial properties.

Findings

SuDs have been applied successfully in different parts of the world; however, the uptake of SuDs, in particular, the retrofit of SuDs, has been restricted by a number of issues including a lack of experience and trust in their performance and a lack of understanding in their true benefits. In particular, there is the limited experience of retrofitting SuDs and there are no well-established procedures for evaluating the feasibility, value or cost effectiveness of doing this.

Social implications

This offers the potential to support the UK government’s flood risk management policy by helping to increase the resilience of properties, whilst offering other benefits to communities such as improvements in air quality and biodiversity and also presenting a clearer understanding of the monetary and non-monetary implication to owners of commercial properties for a more informed and acceptable uptake of SuDs retrofit.

Originality/value

The proposed model will allow a more comprehensive understanding of the costs and associated benefits associated with SuDs retrofit, highlighting the flood risk mitigation benefits that might accrue over a period of time for commercial property.
How operations matters in healthcare standardization
Authors: De Regge Melissa , Gemmel Paul , Meijboom Bert
Published: October 2019

Purpose

Process management approaches all pursue standardization, of which evidence-based medicine (EBM) is the most common form in healthcare. While EBM addresses improvement in clinical performance, it is unclear whether EBM also enhances operational performance. Conversely, operational process standardization (OPS) does not necessarily yield better clinical performance. The authors have therefore looked at the relationship between clinical practise standardization (CPS) and OPS and the way in which they jointly affect operational performance. The paper aims to discuss this issue.

Design/methodology/approach

The authors conducted a comparative case study analysis of a cataract surgery treatment at five Belgium hospital sites. Data collection involved 218 h of observations of 274 cataract surgeries. Both qualitative and quantitative methods were used.

Findings

Findings suggest that CPS does not automatically lead to improved resource or throughput efficiency. This can be explained by the low level of OPS across the five units, notwithstanding CPS. The results indicate that a wide range of variables on different levels (patient, physician and organization) affect OPS.

Research limitations/implications

Considering one type of care treatment in which clinical outcome variations are small complicates translating the findings to unstructured and complex care treatments.

Originality/value

With the introduction of OPS as a complementary view of CPS, the study clearly shows the potential of OPS to support CPS in practice. Operations matters in healthcare standardization, but only when it is managed in a deliberate way on a hospital and policy level.
Experimental study on the characteristic and function of oxide film formed on grinding wheel in ELID precision grinding
Authors: Zhang Jia-Bo , Yang Yang , Zhang Xiao-Hui , Guan Jia-Liang , Zheng Li-Yan , Li Guang
Published: October 2019

Purpose

The purpose of this study is to investigate the characteristic and function of oxide film formed on grinding wheel in electrolytic in-process dressing (ELID) precision grinding and improve the quality of ELID grinding.

Design/methodology/approach

Dynamic film forming experiments were carried out with a simulation device close to the actual processing conditions. Then, the ELID grinding experiments of bearing rings were performed using grinding wheels with good film forming effect. The experiment was designed by quadratic regression general rotation combination method. The influence of grinding depth, electrolytic voltage, duty cycle and grinding wheel linear speed on grinding effect is analyzed.

Findings

A mathematical model for the formation rate of oxide film was established. The experiments show that the composition of grinding wheel and grinding fluid, as well as the electrical parameters, influence the film forming effect. Thus, the oxide film plays an important role in ELID grinding.

Originality/value

This study provides a reference for the design and selection of grinding wheel and grinding fluid and the setting of process parameters in ELID grinding.
Familiarity and format: cause-related marketing promotions in international markets
Authors: Singh Sangeeta , Duque Lola C.
Published: October 2019

Purpose

The purpose of this paper is to demonstrate cause-related marketing (CRM) promotions as a brand-oriented international market entry strategy that can leverage an unfamiliar brand in a new international market. One of the challenges CRM promotions face is skepticism toward the campaign and for that reason, many brands form alliances with well-known charities familiar to the consumer, hoping that the trust and goodwill generated by the charity will be transferred to the brand. The authors manipulate price and donation presentation formats to show an alternative means for overcoming skepticism.

Design/methodology/approach

The research is undertaken in two studies. Study 1 uses a sample collected on Amazon’s MTurk, whereas study 2 is undertaken in the real world with participants from Norway. Analysis of variance and partial least square are, respectively, used to test the hypotheses.

Findings

The first study shows that presenting the donation explicitlyvis-à-visthe price makes a less familiar charity produce the same trustworthy effects as that a well-known one does. Moreover, the second study shows that it strengthens utility from the transaction and weakens skepticism of CRM promotions to impact brand evaluations.

Research limitations/implications

The primary focus of the research was consumers’ familiarity with the charity but other variables could have a significant impact in judgments. For instance, the importance consumers attach to the cause that the charity supports, spatial distance of the brand and charity, brand familiarity. Manipulating these in future studies would not only contribute to the CRM literature but also to that of international marketing.

Practical implications

Firms in international markets can derive competitive advantages with the help of CRM campaigns. Moreover, alliances with familiar charities that are local can help combat nationalistic feelings prevalent in many markets. The separated presentation format can also help overcome some of the additional skepticism found in international markets.

Social implications

The findings support the Better Business Bureau’s Standards for Charity Accountability that seek transparency in communicating CRM promotions. The explicit presentation of price and donation, in addition to providing this transparency, also gives consumers a clear understanding of the CRM promotions’ details, which will increase their self-efficacy in making more informed decisions.

Originality/value

This research contributes to strengthening knowledge on donation-price formats, offers brands entering international markets a singular way of gaining credibility and competitive advantage, and empirically confirms the proposed outcomes of a theoretical model for promotions.
Exploring the motivation of affect management in fostering social media engagement and related insights for branding
Authors: Saleem Fathima Zahara , Iglesias Oriol
Published: October 2019

Purpose

The purpose of this paper is to present an affect-based perspective to explain levels of social media engagement.

Design/methodology/approach

This study uses face-to-face long interviews and online observation of the Facebook profiles of respondents over an eight-month period.

Findings

Social media engagement varies depending on a user’s current and desired affective state. When individuals are in a low to moderately aroused negative affective state (such as feeling bored or upset), individuals tend to spend time passively consuming content: the lowest level of engagement. In a low to moderately aroused positive mood state (such as happiness), users both passively consume and actively participate with relevant content by liking and commenting on existing content. When users are in a highly aroused positive affective state, the propensity to create original content is greater, reflecting the highest level of engagement. When users are in a highly aroused negative affective state (such as being angry at a brand), users are motivated to vent on social media to manage the mood. Conversely, when users are in a highly aroused negative affective state related to personal trauma, the avoidance of engagement on social media is evident.

Practical implications

Brands can increase the likelihood of consumers creating positive consumer–brand stories offline and online by priming consumer affect.

Originality/value

This study explores how a desired affective state motivates varying levels of user engagement with different types of content on social media.
Exploring process recording in behavioural ethics education
Authors: Simola Sheldene
Published: October 2019

Purpose

The purpose of this paper is to introduce, illustrate and explore the use of process recording as a pedagogical tool in behavioural ethics education.

Design/methodology/approach

An overview of the nature and components of process recording as a pedagogical tool is provided. Potential challenges and benefits associated with its use are described. The particular relevance of process recording for behavioural ethics education is highlighted. Illustrative examples of ethics-related process records are discussed.

Findings

Process recording shows promise as a pedagogical technique for meeting three goals of behavioural ethics education (i.e. Chugh and Kern, 2016). These include: enhancing literacy with research-supported concepts and principles such that these can be applied in “real-world” settings; increasing student awareness of gaps that might exist between their intended and actual ethical behaviour; and, fostering the sense that ethical skills are not static, but rather, open to development.

Research limitations/implications

This paper introduces, illustrates and explores the use of process recording in behavioural ethics education. Additional, more systematic study of process recording in ethics education would be useful.

Practical implications

Process recording shows promise as a tool for supporting learning about behavioural ethics. Practical information on its use and concrete examples are provided.

Originality/value

Despite the need for pedagogical tools in behavioural ethics education, as well as the previously identified relevance of process recording as a potential tool in ethics education, there has been no prior exploration or illustration of process recording within this realm.
Real estate ownership and life satisfaction in transition countries
Authors: Anderson John Edwin
Published: October 2019

Purpose

The purpose of this study is to test the hypothesis that real estate ownership contributes to life satisfaction in transition countries.

Design/methodology/approach

Life in Transition survey data are used to model reported life satisfaction using ordinary least squares, ordered probit, generalized ordered logit and bivariate probit models. The hypothesis tested is whether real estate ownership is associated with greater reported life satisfaction.

Findings

Empirical results from the variety of empirical models estimated strongly support the hypothesis that real estate ownership is associated with greater reported life satisfaction in transition countries.

Research limitations/implications

Analysis is limited because life satisfaction is self-reported and specifically for residents of transition countries.

Practical implications

Results confirm that ownership of a home, second home or land parcel is associated with greater life satisfaction.

Social implications

Real estate ownership can be an effective means to improve life satisfaction, especially in societies needing such improvements.

Originality/value

This is the first study of the link between real estate ownership and life satisfaction specifically in transition countries, and using a robust set of empirical models to address issues of ordinal dependent variables, varying coefficient estimates across dependent variable response categories, endogeneity and causality.
Environmental sustainability: a strategic value in guiding cruise industry management
Authors: Ramoa Carlos Eduardo de Almeida , Flores Luiz Carlos da Silva , Herle Felix Bernhard
Published: October 2019

Purpose

In a systemic approach, a ship is a system in which people and organizations interact directly and indirectly in all processes from construction, during the route and at the destination, throughout its useful life, until eventual scrapping or disposal process. The purpose of this paper is to take on the UN 2030 Agenda ‒ Goal 14 to propose a management model that meets environmental guidelines for assessing impacts caused by the cruise ships.

Design/methodology/approach

To verify the proposed model, a quantitative survey using non-probability purposive sampling was conducted among ports, environmental sustainability experts and ocean cruise companies. The empirical data were analyzed using descriptive statistics and structural equation modeling.

Findings

Findings have confirmed five environmental requirements that shipping companies must manage on their cruise ships to meet Goal 14: input management, waste management, air quality, energy management and water management. Adopting and disseminating sustainable development models provides transparent information about actions taken and results of environmental management, and it may change the perception of the organization’s image, which is relevant to win and maintain environment-friendly customers, adding intangible value to the tourism product.

Research limitations/implications

One of the limitations of the study is the research sample, especially ocean cruise companies, which can have biased results, as they are potential sources of environmental impacts. However, this was not the case, since the answers were similar to those of the other two groups surveyed.

Originality/value

The originality of the study is justified by researchers who argue that information provided by shipping companies on sustainability is very limited, as according to previous research, the convergence between strategy formulation model and environmental sustainability as a principle to be incorporated into the management of oceangoing vessels has not been studied.
Top-down knowledge hiding and innovative work behavior (IWB): a three-way moderated-mediation analysis of self-efficacy and local/foreign status
Authors: Arain Ghulam Ali , Bhatti Zeeshan Ahmed , Hameed Imran , Fang Yu-Hui
Published: October 2019

Purpose

This paper aims to examine the consequences for innovative work behavior (IWB) of top-down knowledge hiding – that is, supervisors’ knowledge hiding from supervisees (SKHS). Drawing on social learning theory, the authors test the three-way moderated-mediation model in which the direct effect of SKHS on IWB is first mediated by self-efficacy and then further moderated by supervisor and supervisee nationality (locals versus foreigners).

Design/methodology/approach

The authors collected multi-sourced data from 446 matched supervisor-supervisee pairs working in a diverse range of organizations operating in the Kingdom of Saudi Arabia. After initial data screening, confirmatory factor analysis was conducted to test for the factorial validity of the used measures with AMOS. The hypothesized relationships were tested in regression analysis with SPSS.

Findings

Results showed that SKHS had both direct and mediation effects, via the self-efficacy mediator, on supervisee IWB. The mediation effect was further moderated by supervisor and supervisee nationality (local versus foreigners), which highlighted that the effect was stronger for supervisor–supervisee pairs that were local-local or foreigner-foreigner than for pairs that were local-foreigner or foreigner-local.

Originality/value

This study contributes to both knowledge hiding and IWB literature and discusses the useful theoretical and practical implications of the findings.
Studying the interrelationship between third party logistic service provider enablers using ISM methodology
Authors: Jha P.C. , Aggarwal Remica , Singh Surya Prakash
Published: October 2019

Purpose

The purpose of this research is to first explore various third party logistic service provider supply chain enablers. Thereafter the interrelationship amongst the various supply chain enablers has been studied using ISM Methodology. Despite the complex relationships third party logistic service providers (3PLs) share with their clients or firms, they often attract a demand owing to the flexibility and competitive edge they provide to their client firms in adapting to the rapidly changing market conditions, focusing on their core competencies and developing long-term growth strategies for them. Choosing and evaluating the right third-party logistic service provider is an important responsibility for logistic managers. This largely depends on selecting appropriate 3PLs supply chain enablers that assess the 3PLs on different fronts.

Design/methodology/approach

This paper presents an ISM approach for studying the interrelationships between various 3PLs enablers and accordingly constructing a hierarchical structure of them.

Findings

The results suggest that delivery, service reliability and risk and uncertainty factors have the highest importance.

Research limitations/implications

Selection of the 3PLs is a critical issue when they are required to be selected by the company at the global level. This often requires doing a comparative study for both domestic as well as global service providers. Choosing appropriate supply chain enablers as the basis for selection of 3PLs therefore will serve as a research topic to be further explored both by researchers as well as company managers. Further studying the inter-relationships amongst various supply chain enablers will provide basis to managers to justify their choice.

Originality/value

The novelty of the research lies in the application of methodology to the case of third-party logistic service provider selection
Inclusive language regarding gender, sexual orientation, and relationship status: the ongoing process and outcome of revising psychiatric materials
Authors: Drill Rebecca , Malone Johanna , Flouton-Barnes Meredith , Cotton Laura , Keyes Sarah , Wasserman Rachel , Wilson Kelly , Young Monica , Laws Holly , Beinashowitz Jack
Published: October 2019

Purpose

The purpose of this paper is to address the barrier to care experienced by LGBTQIA+ populations by binary language for gender, sexual orientation and relationship status.

Design/methodology/approach

The authors review the research that shows linguistic barriers are a significant obstacle to healthcare for LGBTQIA+ communities. The authors describe both a process and revisions for addressing language bias in psychiatric intake/research research materials as well as quantify its impact in an adult psychotherapy clinic in a public hospital.

Findings

Patients self-identified their gender, sexual orientation and relationship status in a variety of ways when not presented with binaries and/or pre-established response choices. In addition, the non-response rate to questions decreased and the authors received positive qualitative feedback. The authors also present the revisions to the intake/research materials.

Practical implications

Other healthcare settings/clinicians can revise language in order to remove significant barriers to treatment and in doing so, be welcoming, non-pathologizing and empowering for LGBTQIA+ consumers of mental health services (as well as for non-LGBTQIA+ consumers who are in non-traditional relationships).

Social implications

This work is one step in improving healthcare and the healthcare experience for LGBTQIA+ communities and for those in non-traditional relationships.

Originality/value

This work is set in a public safety-net hospital providing care for underserved and diverse populations. This paper describes the process of revising psychiatric materials to be more inclusive of the range of self-identity are: gender, sexual orientation and relationship status.
Enabling mental health student nurses to work co-productively
Authors: Best Stephanie , Koski Arja , Walsh Lynne , Vuokila-Oikkonen Päivi
Published: October 2019

Purpose

The purpose of this paper is to investigate the use of innovative teaching methods and share a four-step model, to promote the use of co-production in mental health practice.

Design/methodology/approach

The case study approach highlights three real-life examples of day to day experiences in mental health nurse education with innovative approaches to sharing and developing co-production skills and attitudes in mental health student nurses.

Findings

The case studies highlight three settings where undergraduate mental health nurses experience co-production through a world café event and dialogical community development. Common themes include setting the environment, developing a common aim and relationship building.

Research limitations/implications

A limitation of this paper is that only three case studies are provided, further examples would provide a greater pool of exemplars for others to draw on. However, by focusing upon student nurse education in learning environment, these examples are transferable to other settings.

Practical implications

The practical applications are summarised in a four-step model that can help develop co-productive teaching methods; enable educators to set the climate and generate an understanding of co-production that empowers students and service users.

Social implications

The emphasis and relevance of promoting co-productive working habits early on in nurses’ mental health nursing careers will enable them to raise awareness of future social implications for a range of client groups.

Originality/value

Authors: Ropo Arja , Mäkinen Elina I. , Seppä Inka
Published: October 2019

Purpose

The purpose of this paper is to examine how companies that characterise their leadership style as plural, shared or distributed narrate their actions and practices in online blog texts.

Design/methodology/approach

The data consist of online blog texts published by seven Finnish IT companies. The analytical strategy draws on both thematic and structural approach to narrative analysis. The blog texts were analysed thematically to uncover different aspects of plural leadership. The analysis revealed a narrative pattern consisting of three categories that explain why and how companies implemented plural leadership.

Findings

The first category in the narrative pattern describes the motivation for engaging in plural leadership. The second category explains how the companies broke down existing hierarchies in order to create new flexible work roles. The third category describes how the organisations sought to create a communal culture and a strong sense of trust using symbols, material objects and spaces.

Research limitations/implications

The study contributes to leadership research that emphasises post-heroic leadership conceptualisations. The narrative pattern provides future empirical studies a framework for analysing plural leadership practices in different organisational settings. Whereas this study sheds light on the ways in which organisations and their leadership practices can be investigated using online data, traditional organisational ethnographies can make a further contribution to this line of research.

Practical implications

Implementing plural leadership in organisations can lead to informal power plays. Attention should be paid on to how plural leadership evolves in flat hierarchies and promotes community building.

Originality/value

Company webpages have rich information on how companies operate and perceive themselves. They provide yet another window for observing organisational activities. This study makes a novel contribution to how plural leadership is practiced and conceptualised in online blog texts.
Knowledge sharing in NGOs: the importance of the human dimension
Authors: Zbuchea Alexandra , Ivan Loredana , Petropoulos Sotiris , Pinzaru Florina
Published: October 2019

Purpose

The purpose of this paper is to show the way the human dimension influences the adoption and usage of the knowledge transfer in non-profit organizations (NGOs). Previous research on the topic focused mainly on the organizational and technical aspects (i.e. organizational culture, processes and technology), lacking a consistent approach of the human dimension. Therefore, this paper goes beyond the multiplying effect of the organizational and technical factors in the development of knowledge transfer and investigates the impact of human beliefs and actions on the practices of knowledge sharing in the NGOs.

Design/methodology/approach

This paper investigates the above-mentioned topics of the importance of the human aspect in the knowledge sharing adoption, and development of the NGOs by use of a cross-cultural study based on a questionnaire that conducted in Romania and Greece.

Findings

This study emphasizes the importance of the human dimension in the practice of the knowledge sharing of the non-profit organizations, proving that the adoption of such practices depends on the beliefs of the NGOs employees on the topic, and on their degree of exposure to international activities.

Practical implications

The results of this study provide valuable incentive to the managers of the non-profit organizations to pay more attention to the beliefs and values of their employees in adopting knowledge sharing practices.

Originality/value

This paper is valuable to the academics and practitioners in search of reliable data on the impact of the human dimension on the adoption and usage of knowledge management in the Third Sector, filling an existing gap of the literature on the topic.
Building an institutional repository: the case of University of Ilorin, Library, Nigeria
Authors: Eromosele George Osas
Published: October 2019

Purpose

An institutional repository has become a new way of making the intellectual outputs of academic and research institutions electronically accessible in the online public domain. The outcome has led to users gaining remote access to varieties of digitized information that is hitherto locally resident before digitization in hardcopy form in the various information centre and libraries without users’ restrictions. This initiative has helped to enhance the open access inventiveness. Nigeria libraries are therefore taking up the challenge of computerizing their libraries and some have taken some steps to source the requisite funds to digitize and archive their library resources for easier Web-based access. Consequent upon this development, the University of Ilorin, embarked on digitization of its local contents such as Convocation Ceremonies; Government Publications; and Staff Publications and Theses and Dissertations, and making these local resources available online. This paper attempts to give a detailed account, step-by-step procedures and the various challenges faced in the process of building its online institutional repository and the way forward. The report in this paper gives insight into academic libraries intention to digitize their library resources, on the best way to go about it and also to avoid unnecessary hurdles.

Design/methodology/approach

To provide a thorough breakdown of the building of institutional repositories in the University of Ilorin, Library, webliography sources were consulted.

Findings

Some areas in service provisions need to improve upon, and these areas are search engine optimization by subscribing to handle.net, integration of Google analytics to check performance, sitemap features and highly secured (SSL and public key encryption.

Originality/value

This paper attempts to give a detailed account, step-by-step procedures and the various challenges faced in the process of building its online institutional repository and the way forward. The report in this paper gives insight into academic libraries intention to digitize their library resources, on the best way to go about it and also to avoid unnecessary hurdles.
