A mesoderm-independent role for Nodal signaling in convergence & extension gastrulation movements
Authors: Williams Margot L.K. , Solnica-Krezel Lilianna
Published: June 2019

During embryogenesis, the distinct morphogenetic cell behavior programs that shape tissues are influenced both by the fate of cells and their position with respect to the embryonic axes, making embryonic patterning a prerequisite for morphogenesis. These two essential processes must therefore be coordinated in space and time to ensure proper development, but mechanisms by which patterning information is translated to the cellular machinery that drives morphogenesis remain poorly understood. Here, we address the role of Nodal morphogen signaling at the intersection of cell fate specification, patterning, and anteroposterior (AP) axis extension in zebrafish gastrulae and embryonic explants. AP axis extension is impaired in Nodal-deficient embryos, but it is unclear whether this defect is strictly secondary to their severe mesendoderm deficiencies or also results from loss of Nodal signalingper se. We find that convergence & extension (C&E) gastrulation movements and underlying mediolateral (ML) cell polarization are reduced in the neuroectoderm of Nodal-deficient mutants and exacerbated by simultaneous disruption of Planar Cell Polarity (PCP) signaling, demonstrating at least partially parallel functions of Nodal and PCP. ML polarity of mutant neuroectoderm cells is not fully restored upon transplantation into wild-type gastrulae, demonstrating a cell autonomous, mesoderm-independent role for Nodal in neural cell polarization. This is further demonstrated by the ability of Nodal ligands to promote neuroectoderm-driven C&E of naïve blastoderm explants in a tissue-autonomous fashion. Finally, temporal manipulation of signaling reveals that Nodal contributes to neural C&E in explants after mesoderm is specified and promotes C&E even in the absence of mesoderm. Together these results reveal a mesoderm-independent, cell-autonomous role for Nodal signaling in neural C&E that may cooperate with previously-described mesoderm-dependent mechanisms to drive AP embryonic axis extension.
Edem1 activity in the fat body regulates insulin signalling and metabolic homeostasis in Drosophila
Authors: Pathak Himani , Varghese Jishy
Published: June 2019

In Drosophila, nutrient status is sensed by the fat body, a functional homolog of mammalian liver and white adipocytes. The fat body conveys nutrient information to insulin-producing cells (IPCs) through humoral factors which regulate Drosophila insulin-like peptide (DILP) levels and insulin signalling. Insulin signalling has pleiotropic functions, which include the management of growth and metabolic pathways. Here, we report that Edem1 (endoplasmic reticulum degradation-enhancing α-mannosidase-like protein 1), an endoplasmic reticulum-resident protein involved in protein quality control, acts in the fat body to regulate insulin signalling and thereby the metabolic status in Drosophila. Edem1 limits the fat body derived Drosophila TNFα Eiger activity on IPCs and maintains systemic insulin signalling in fed conditions. During food deprivation, edem1 gene expression levels drop, which aids in the reduction of systemic insulin signalling crucial for survival. Overall we demonstrate that Edem1 plays a vital role in helping the organism to endure a fluctuating nutrient environment by managing insulin signalling and metabolic homeostasis.
Embedding to Reference t-SNE Space Addresses Batch Effects in Single-Cell Classification
Authors: Poličar Pavlin G. , Stražar Martin , Zupan Blaž
Published: June 2019

Dimensionality reduction techniques, such as t-SNE, can construct informative visualizations of high-dimensional data. When working with multiple data sets, a straightforward application of these methods often fails; instead of revealing underlying classes, the resulting visualizations expose data set-specific clusters. To circumvent these batch effects, we propose an embedding procedure that takes a t-SNE visualization constructed on a reference data set and uses it as a scaffold for embedding new data. The new, secondary data is embedded one data-point at the time. This prevents any interactions between instances in the secondary data and implicitly mitigates batch effects. We demonstrate the utility of this approach with an analysis of six recently published single-cell gene expression data sets containing up to tens of thousands of cells and thousands of genes. In these data sets, the batch effects are particularly strong as the data comes from different institutions and was obtained using different experimental protocols. The visualizations constructed by our proposed approach are cleared of batch effects, and the cells from secondary data sets correctly co-cluster with cells from the primary data sharing the same cell type.

Published: June 2019

Sizable metal-ion-doped YBa2Cu3O7−δ single crystals with high uniformity have been in great demand for fundamental studies on superconductivity. This article reports a novel approach, based on top-seeded solution growth and characterized by using an Fe-added Y2O3 crucible, to effectively enhance the homogeneity of YBa2(Cu1−x
Fe

)3O7−δ single crystals. Because Fe ions are absorbable on or dissolvable from the Fe-Y2O3 crucible, it functions as a reservoir, yielding a stable Fe concentration in the liquid. Consequently, a series of acceptably sized YBa2(Cu1−x
Fe
x
)3O7−δ single crystals with better uniformity than those grown by previous methods were obtained. The new dopant-added crucible, capable of balancing the solution spontaneously, is broadly applicable for preparing other doped single crystals.

HL acts as an N,N′,O-tridentate ligand in both complexes. Complex (I) crystallizes in the orthorhombic space group Pbcn and has a mononuclear structure, the azide co-ligand is not involved in crystallization and the Ni2+ centre lies in a distorted {N4O2} octahedral coordination environment. Complex (II) crystallizes in the triclinic space group P\overline{1} and is a centrosymmetric binuclear complex with a crystallographically independent Cu2+ centre coordinating to three donor atoms from the deprotonated L
− ligand and to two N atoms belonging to two bridging azide anions. The two- and one-dimensional supramolecular structures are constructed by hydrogen-bonding interactions in (I) and (II), respectively. The in vitro urease inhibitory evaluation revealed that complex (II) showed a better inhibitory activity, with the IC50 value being 1.32±0.4 µM. Both complexes can effectively bind to bovine serum albumin (BSA) by 1:1 binding, which was assessed via tryptophan emission–quenching measurements. The bioactivities of the two complexes towards jack bean urease were also studied by molecular docking. The effects of the metal ions and the coordination environments in the two complexes on in vitro urease inhibitory activity are preliminarily discussed.
A new crystalline form of αβ-D-lactose prepared by oven drying a concentrated aqueous solution of D-lactose
Authors: Nicholls Daniel , Elleman Carole , Shankland Norman , Shankland Kenneth
Published: June 2019

A new crystalline form of αβ-D-lactose (C12H22O11) has been prepared by the rapid drying of an approximately 40% w/v syrup of D-lactose. Initially identified from its novel powder X-ray diffraction pattern, the monoclinic crystal structure was solved from a microcrystal recovered from the generally polycrystalline mixed-phase residue obtained at the end of the drying step. This is the second crystalline form of αβ-D-lactose to be identified and it has a high degree of structural three-dimensional similarity to the previously identified triclinic form.

Published: June 2019

The asymmetric unit of the title compound, C15H12N2O2, contains two crystallographically independent molecules in which the dihedral angles between the benzene rings in each are 13.26 (5) and 7.87 (5)°. An intramolecular O—H...N hydrogen bonds results in the formation of an S(6) ring motif. In the crystal, molecules are linked by weak C—H...O and C—H...N hydrogen bonds, forming layers parallel to (011). In addition, π–π stacking interactions with centroid–centroid distances in the range 3.693 (2)–3.931 (2) Å complete the three-dimensional network.
Sub-sector branding and nation branding: the case of higher education
Authors: Sataøen Hogne Lerøy
Published: June 2019

Purpose

This paper concerns public sub-sector branding within the higher education (HE) system. The purpose of this paper is to investigate how public sub-sector branding within HE is organized and how it is influenced by the use of national values, traits and characteristics.

Design/methodology/approach

The study relies on two data sources: first, the paper benefits from a data set of one-stop web-portals for HE from the 23 countries listed inTimes Higher Education’s top-60 universities ranking. Second, it builds on a sample and brief overview of Norway’s sub-sector branding of its HE sector.

Findings

Expert authorities within the HE sector are legally and organizationally responsible for sub-sector branding, and they establish coordinated and coherent web-portals. In practice, however, nation-branding concerns are influencing on how the HE sub-sector is branded. The paper concludes with a discussion of democratic implications, and points to paradoxes arising from the use of national clichés and characteristics in this highly international sub-sector of the public realm.

Originality/value

The paper informs discussions about public sub-sector branding within HE, a phenomenon that thus far has not been systematically studied. The practical applications of such a study are evident, as branding is becoming more important in the public sector in general, and in HE in particular.
Building a modern economic system: basic framework, key issues, and theoretical innovation
Authors: Liu Zhibiao
Published: June 2019

Purpose

The construction of a modern economic system is a symbolic and strategic choice for large developing economies on the path toward high-quality economic development. The paper aims to discuss this issue.

Design/methodology/approach

The overall framework aims to adhere to “One Policy and One Mainline” to build an innovation-driven, synergistic industrial system and a “with three-qualities” economic system (with efficient market mechanisms, energetic micro-agents and appropriate macroeconomic regulation).

Findings

The strengthening of the real economy and construction of a modern industrial system constitute the material basis for supporting this system and framework. As major decision making and theoretical innovation in empirical practice, building a modern economic system can also contribute substantially toward developing the applied economic theory of socialism with Chinese characteristics.

Originality/value

Building a modern economic system in China necessitates, without exception, the construction of various subsystems encompassing industrial, market, distribution, regional development, green development, open and economic institutional aspects.
Aligning our work to the world we all want – why conscious sustainability makes good business sense?
Authors: Wilson Clive
Published: June 2019

Purpose

The purpose of this paper is to raise the awareness of business leaders to the opportunity presented by the United Nations Sustainable Development Goals (SDGs).

Design/methodology/approach

The paper provides a brief account of the author’s experience of running workshops which engaged thousands of people from age 7 to well over 70 across three continents. It also points the reader in the direction of several case studies, suggesting that alignment to the global agenda makes business sense.

Findings

The first finding is that most people want the same world to be passed to future generations. Second, this world is consistent with the one described by the SDGs. Third, businesses are discovering that alignment to this vision makes good business sense.

Practical implications

There is significant opportunity for business leaders to consider the world we live in and align their strategies to the global agenda.

Social implications

Failure to deliver the SDGs will cause significant disruption to or even collapse of society as we know it. Getting business involved is good for the future of humanity and the world we inhabit.

Originality/value

There are many papers on the SDGs but, to the best of the author’s knowledge, none make the link between the SDGs and the world most people want for future generations. This factor alone should be enough to inspire business leaders to take note.
Knowledge hiding in organizations: everything that managers need to know
Authors: Anand Payal , Hassan Yusuf
Published: June 2019

Purpose

Though there have been umpteen discussions on knowledge sharing in organizations, there is a dearth of discussion on knowledge hiding acts, especially in learning organizations. The purpose of this paper is to introduce this novel construct “knowledge hiding” and to highlight its relevant aspects crucial to organizations.

Design/methodology/approach

The paper reviews published articles on knowledge hiding and proposes four broad categories to distinguish the causes of knowledge hiding. This paper further suggests substantial measures that managers need to emphasize for dealing with the dimensions that influence knowledge hiding acts, to alleviate or mitigate the causes behind knowledge hiding acts at the workplace.

Findings

This paper identifies the causes of knowledge hiding behaviors and segregates these causes under four broad categories, i.e. person-related, job-related, coworkers-related, and organization-related causes.

Originality/value

This paper provides valuable information on knowledge hiding acts in the workplace to the practitioners in a simplified structure, along with some practical remedies to manage such acts.
Collaborative knowledge management for corporate ecological responsibility
Authors: Guo Weiwei
Published: June 2019

Purpose

Knowledge has become the basis of enhancing the core competitiveness of enterprises in this era of knowledge-driven economies. Collaborative knowledge management not only realizes the real-time exchange and communication of knowledge among different enterprises, but also facilitates the collaboration and integration of knowledge. Collaborative knowledge management has been successfully applied to different fields. To address the poor ecological responsibility of enterprises, the purpose of this paper is to introduce the concept of collaborative knowledge management in this research to determine if the evolution of the decision-making process in collaborative knowledge management is involved in corporate ecological responsibility (CER).

Design/methodology/approach

This research established an evolutionary game model of collaborative knowledge management for CER. The behavioral, evolutionary law and stable behavioral, evolutionary strategy of the participants was identified according to the replicator dynamics equation. Simulation analysis was conducted using MATLAB software.

Findings

Research results demonstrated that, first, the strategic selection of firms is influenced by cost and interest coefficients. Second, the strategy, selection of enterprises, is related to the common benefits of enterprise cooperation. Third, during the systematic evolution and stabilization of strategies, enterprises adopt the same knowledge strategies.

Originality/value

On the basis of the research findings, policy suggestions were proposed to encourage enterprises to implement collaborative knowledge management strategies in ecological responsibility.
Multiple patent network analysis for identifying safety technology convergence
Authors: Jeon Jeonghwan , Suh Yongyoon
Published: June 2019

Purpose

Using the large database of patent, the purpose of this paper is to structure a technology convergence network using various patent network analysis for integrating different results according to network characteristics.

Design/methodology/approach

The patent co-class analysis and the patent citation analysis are applied to discover core safety fields and technology, respectively. In specific, three types of network analysis, which are centrality analysis, association rule mining analysis and brokerage network analysis, are applied to measure the individual, synergy and group intensity.

Findings

The core safety fields derived from three types of network analysis used by different nature of data algorithms are compared with each other to understand distinctive meaning of cores of patent class such as medical safety, working safety and vehicle safety, differentiating network structure. Also, to be specific, the authors find the detailed technology contained in the core patent class using patent citation network analysis.

Practical implications

The results provide meaningful implications to various stakeholders in organization: safety management, safety engineering and safety policy. The multiple patent network enables safety manager to identify core safety convergence fields and safety engineers to develop new safety technology. Also, in the view of technology convergence, the strategy of safety policy can be expanded to collaboration and open innovation.

Originality/value

This is the initial study on applying various network analysis algorithms based on patent data (class and citation) for safety management. Through comparison among network analysis techniques, the different results are identified and the collective decision making on finding core of safety technology convergence is supported. The decision maker can obtain the various perspectives of tracing technology convergence.
Numerical simulation of fracture characteristics of jointed rock masses under blasting load
Authors: Liu Chao , Yang Mingyang , Han Haoyu , Yue Wenping
Published: June 2019

Purpose

To study fracture characteristics of jointed rock masses under blasting load, the RFPA2D analysis software for dynamic fracture of rocks based on the finite element method and statistical damage theory was used.

Design/methodology/approach

On this basis, this research simulated the fracture process of rock masses in blasting with different joint geometrical characteristics and mainly analysed the influences of distance from joints to blasting holes, the length of joints, the number of joints and joint angle on fracture of rock masses.

Findings

The calculation results show that with the constant increase of the distance from joints to blasting holes, the influences of joints on blasting effects of rock masses gradually reduced. Rock masses with long joints experienced more serious damages than those with short joints. Damages obviously increased with the changing from rock masses without joints to rock masses with joints, and when there were three joints, the further increase of the number of joints had unobvious changes on blasting effects of rock masses. Joints showed significant guidance effect on the propagation of cracks in blasting: promoting propagation of main vertical cracks deflecting to the ends of joints.

Originality/value

The research results are expected to provide some theoretical bases in practical application of engineering blasting.
Post-occupancy evaluation: a review of literature
Authors: Roberts C.J. , Edwards David John , Hosseini M. Reza , Mateo-Garcia Monica , Owusu-Manu De-Graft
Published: June 2019

Purpose

The purpose of this paper is to analyse extant literature on POE of a building’s operations and performance as a means of holistically mapping the existing body of knowledge (BOK); identify impediments preventing its wide-scale adoption throughout practice; and develop new theory that seeks to integrate digital technologies (such as building information modelling (BIM)) within facilities management (FM) via a POE feedback mechanism.

Design/methodology/approach

An inductive and interpretivist methodological approach is adopted that utilises a mixed methods systematic review to map bibliometric data on the POE, associated underpinning processes and benchmarking facilities. Publication and citation metrics are produced via the software VOSviewer to determine the extent to which POE interrelates with other fields of study (namely, digital technologies and FM).

Findings

The BOK accrued illustrates that whilst POE has received comparatively scant academic attention in comparison to other fields of study, interest in the area is growing. The work also identifies that a stronger community of practice (CoP) is needed (that comprises of academics and practitioners) to ensure that a consistent approach to POE implementation is developed and that the barriers to POE implementation are addressed.

Originality/value

Findings presented accentuate the need for design practitioners to reverse engineer POE implementation to inform future design vis-à-vis simply reporting upon an existing building’s performance post construction. Other new theories are also introduced as a means of engendering wider academic discourse in this field of science.
The gift in shared HRM ethics in SMEs
Authors: Adla Ludivine , Gallego-Roquelaure Virginie
Published: June 2019

Purpose

The purpose of this paper is to understand how the relationship of gifts/counter-gifts between actors enables us to build an HRM policy that we call “shared and ethical”. It is shared because it is co-constructed by both owner-manager and employees, and ethical because it is deemed desirable by the players and meets their expectations. This approach aims to make HRM more responsible in view of the commitments made by stakeholders.

Design/methodology/approach

Drawing upon the Maussian theory of gift/counter-gift, a longitudinal and retrospective study was conducted over a period of three years with a French SME.

Findings

The authors highlight two key stages in the gift process: the initial gift of the owner-manager, which is reflected in the establishment of a social pact, and the gap in perception between employees’ contribution and the counter-gift expected of the owner-manager. The authors show the complexity of the gift-chain by building a shared and ethical HRM and highlight the tensions identified between the existence of tools and mutual adjustments in HRM through gifts and counter-gifts.

Originality/value

Usual HRM in SMEs is centred on the owner-manager. On the contrary this research highlights how an SME can develop an alternative HRM. A longitudinal and retrospective study, carried out with a French SME, led to the construction of a process modelling of a shared HRM ethics.
Brexit: human resourcing implications
Authors: Ridgway Maranda
Published: June 2019

Purpose

Three years on from the Brexit vote, while it remains a central topic for debate in the media, there has been limited discussion about the human resource (HR) implications. The purpose of this paper is to provide theoretical evaluation and informed discussion, distilled into four interconnected propositions, on how employee resourcing as a HR practice may be impacted following actual Brexit decisions.

Design/methodology/approach

Drawing on the employee resourcing literature, the paper adopts a discursive approach which examines how the UK’s decision to exit the European Union will affect HR practice. The paper draws comparison with the global recession since 2008, a similarly unprecedented development in its discussion of employee resourcing practices and draws parallels which may help to inform the future of HR practices in the UK, because of Brexit.

Findings

This paper offers a set of propositions; the flow of talent into the UK may become more restricted and reinvigorate the “war for talent” that followed the effects of the global financial crisis on the UK. To attract and retain workers in relatively lower-skilled roles, employers may be faced with a need to re-skill such roles and adopt more flexible working arrangements. Finally, to meet skilled employment requirements, removal of restrictions to recruit from within the European Economic Area may trigger increased global migration of skilled workers.

Originality/value

This paper contributes to the discussions regarding the implications of Brexit for HR practice by offering propositions to shape future research agendas.
Energy management and its impacts on indigenous communities in Saskatchewan and Alberta
Authors: Datta Ranjan , Hurlbert Margot
Published: June 2019

Purpose

The purpose of this paper is to reveal gaps in knowledge about energy industries, federal and provincial governments and indigenous communities’ energy management policies and practices, as well as to highlight areas requiring further research and knowledge development.

Design/methodology/approach

This paper used a scoping review framework according to scoping methodological framework.

Findings

This paper suggests that researchers need to examine Indigenous communities on past leaks response records, pipelines leaks impacts in their health and environment and current risk management processes and regulations to identify weaknesses. This review paper also suggests that significant time will be required to meaningfully and honestly engage with communities to move from acceptance, through approval, to co-ownership of the project as the firm builds its legitimacy, credibility and trust with Indigenous communities.

Originality/value

The authors introduce an original approach to scoping methodological framework that directly addresses the processes of reveal gaps in knowledge and practice. It offers researchers, policy-makers, community and practitioners an alternative approach which is culturally appropriate for improving economic and environmental health outcomes of marginalised groups.
Management and reforms in the Nordic hospital landscape
Authors: Kirchhoff Ralf , Vik Erlend , Aarseth Turid
Published: June 2019

Purpose

The purpose of this paper is to give a comprehensive and updated analysis of the available academic literature (2000–2016) on management and reforms in the Nordic hospital landscape.

Design/methodology/approach

A systematic literature review was conducted by searching articles in Scopus database, as well as applicable journals.

Findings

The vast majority of the Nordic articles are relatively coherent on the following: first, the reforms have created a change in the manager role or rather there are new expectations about the content of the manager role. Second, the reforms entail tension between profession and administration. Doctors who are managers identify themselves primarily as doctors, implicating that the medical logic has not competed out by an administrative logic. Third, the reforms have brought new opportunities for nurses. Still, nurse managers perceive tension between the profession and administration. Fourth, new public management (NPM) is often the framework or background for understanding change in hospitals or manager roles in the articles. Fifth, the majority of the articles are focusing on management as a general key concept.

Research limitations/implications

The search was limited to the period 2000–2016 and have only included articles published in English. There are several limitations around these choices: first, research published in a language other than English (i.e. Norwegian, Swedish, Finnish or Danish) are excluded. Second, it may take years before consequences of hospital reforms have impact on management and manager roles. Some of the articles are published relatively shortly after the implementation of the reform. Third, many factors in a reform have impact on management or manager roles, thus it is challenging to give simple explanations.

Practical implications

The authors would welcome a more pluralistic approach, and contributions that are not quite so busy describing and criticizing the NPMization of hospitals and management. In particular, the authors look forward to more research on how other reform trends, such as NPG, affect management in hospitals.

Originality/value

This review summarizes the literature on how academic literature (2000–2016) – in a Nordic reform context – has dealt with management in hospitals. The study reflects upon the academic literature per se. There are tendencies to explore reforms and management with some conceptual equivalence.
E-textbook piracy behavior
Authors: Hati Sri Rahayu Hijrah , Fitriasih Rahma , Safira Anya
Published: June 2019

Purpose

The purpose of this paper is to examine the factors that influence the intention of students to pirate academic e-books by integrating three main theories: ethics theory, deterrence theory, and the theory of planned behavior. The study also examines the moderating role of past piracy behavior on the relationship between the factors in the previously mentioned theories and students’ piracy intention.

Design/methodology/approach

The data were collected using a convenience sample of 662 university students. Based on their past behaviors, the students were grouped into “no piracy” and “piracy” groups.

Findings

The result shows that the piracy intention of both the no-piracy and piracy groups has a similar influence based on the moral obligation in ethics theory. The factors in the deterrence theory, which includes fear of legal consequences and perceived likelihood of punishment, have no significant impact on the attitudes of the two groups toward piracy. While the intention of the no-piracy group is not influenced by other internal factors, such as self-efficacy, or by external factors, such as subjective norms and facilitating conditions, the behavioral intention of the piracy group is significantly influenced by these three factors.

Research limitations/implications

This study only focuses on piracy attitude and behavior in the context of e-books.

Practical implications

In Indonesia, the insignificant impact of factors from deterrence theory (the fear of legal consequences and perceived punishment) indicates weak law enforcement to combat digital piracy. Thus, it is imperative that law enforcement, especially regarding piracy, should be enhanced.

Social implications

The significant role of ethics in the attitudes toward piracy indicates that morality serves as a moral compass to fight piracy behavior. The strong impact of subjective norms, especially in the piracy group, suggests that families should raise children and educate youth with beliefs that align with the concepts of morality.

Originality/value

The study integrates three theories that are most often used in piracy behavior studies: ethics theory, deterrence theory, and theory of planned behavior. In addition, the study provides empirical evidence on the moderating role of past experience in piracy behavior.
Volunteering drivers and continuation will: the role of engagement
Authors: Aboramadan Mohammed , Hassi Abderrahman , Alharazin Hatem Jamil , Dahleez Khalid Abed , Albashiti Belal
Published: June 2019

Purpose

As volunteering research in nonprofit organizations is growing significantly, the purpose of this paper is to examine the effects of volunteering drivers and work engagement on volunteer continuation will.

Design/methodology/approach

Building on empirical and theoretical perspectives, the authors hypothesized that work engagement mediates the relationship between volunteering drivers and volunteer continuation will. To verify our hypotheses, we examined data collected from 372 active volunteers from Palestinian nonprofit organizations. The authors conducted structural equations modeling (SEM) analyses using the AMOS 24 platform to investigate direct and indirect effects.

Findings

The results of the study show that work engagement is a significant predictor of volunteer continuation will; mediates the relationship between career driver of volunteering and volunteer continuation will; and mediates the relationship between the protective driver of volunteering and volunteer continuation will.

Research limitations/implications

The research design limits establishing cause and effect relationships among the examined variables.

Practical implications

The results of the current study may be of use for nonprofit organizations managers formulating effective recruitment and training policies to retain their volunteers.

Originality/value

The paper contributes to the limited empirical body of the volunteering research. The study is novel as it is one of the few studies conducted using data coming from a non-western context.
Mattering in digital labor
Authors: Bucher Eliane , Fieseler Christian , Lutz Christoph
Published: June 2019

Purpose

Online gig labor platforms bring together a global and fast-growing workforce to complete highly granular, remote and decontextualized tasks. While these environments might be empowering to some workers, many others feel disenfranchised and removed from the final product of their labor. To better understand the antecedents of continued participation in forms of crowdsourced digital labor, the purpose of this paper is to explore the relationship between worker’s ability to create a narrative of their work mattering regardless, and their continued work engagement (WE) in these work setups.

Design/methodology/approach

The authors approach the relationship between individual mattering and digital WE through a longitudinal study among workers on the crowdworking platform Amazon Mechanical Turk. The authors further provide qualitative insight into individual perceptions of mattering based on essay data.

Findings

The authors develop a measure of mattering in crowdworking with four dimensions: reliance, social recognition, importance and interaction. Reliance is the most pronounced dimension, followed by interaction, importance and social recognition. In the final longitudinal model, only importance affects WE positively, while the other three mattering dimensions do not have a significant effect.

Originality/value

The findings indicate that individuals who feel that they themselves and their work “count” and “make a difference” will be more engaged in their digital labor. By clarifying the dimensionality of mattering in crowdwork and studying its differentiated effect on WE, the paper makes a contribution to research on crowdwork and the future of work. Beyond the theoretical contributions, the finding that perceived importance fosters WE has important implications for task and platform design.
The role of mindfulness in response to abusive supervision
Authors: Burton James P. , Barber Larissa K.
Published: June 2019

Purpose

The purpose of this paper is to explore whether trait and state mindfulness alters the relationship between abusive supervision and interactional justice perceptions, which then predicts supervisor-directed retaliation.

Design/methodology/approach

Study 1 examined these relationships among 230 employees using a cross-sectional survey design. Study 2 further examined these relationships among 263 undergraduate students using a scenario-based, experimental laboratory study.

Findings

In Study 1, counter to predictions, individuals who were higher in trait mindfulness were most likely to view an abusive supervisor as unfair. Exploratory analyses suggested that this effect was isolated to the mindfulness dimension of being highly attentive to moment-to-moment experiences. Study 2 replicated this effect with state mindfulness (specifically, attention to one’s present moment).

Practical implications

Organizations should consider how mindfulness interventions might not always be useful – and potentially counterproductive – for affecting perceptions of and reactions to some stressful work situations like abusive supervision.

Originality/value

Little research has been done on how mindfulness affects perceptions of and reactions to abusive supervisors. The authors expected mindfulness could reduce the negative effect of supervisor abuse on interactional justice perceptions, as well as the effect of interactional injustice on retaliation. However, within the context of abusive supervision, training individuals to become more mindful may actually predict lower levels of interactional justice, resulting in more supervisor-directed retaliation.
Discriminant validity of the customer-based corporate reputation scale: some causes for concern
Authors: Radomir Lăcrămioara , Moisescu Ovidiu I.
Published: June 2019

Purpose

This study aims to reexamine the discriminant validity of the customer-based corporate reputation (CBR) scale in both its original and short forms.

Design/methodology/approach

The authors used data from end-use customers in two countries and two service industries. Results obtained in partial least squares structural equation modeling for the heterotrait–monotrait (HTMT)-based inference test and the Fornell and Larcker criterion were compared to make judgements about the empirical distinctiveness of the CBR scale’s five dimensions.

Findings

This study’s findings demonstrate that the CBR scale in both its original and short forms lacks discriminant validity when using the HTMT-based inference test. Conversely, the discriminant validity of the five corporate reputation dimensions is generally supported when using the more liberal Fornell and Larcker criterion.

Research limitations/implications

Future studies using the CBR scale in either the original or its short form should rely on the more stringent HTMT criterion to ensure the discriminant validity of the scale’s five dimensions.

Originality/value

By addressing recent findings regarding the HTMT criterion’s superiority in uncovering discriminant validity issues compared to that of the Fornell and Larcker criterion, this study is the first, to the best of the authors’ knowledge, to reexamine the discriminant validity of the well-known CBR scale.
A study on the mediating effect of residential loans on total real estate loans of banks in India
Authors: Aggarwal Tanu , Solomon Priya
Published: June 2019

Purpose

The purpose of this paper is to examine the impact of residential and commercial loans on total real estate sector loans by using partial least square–structured equation modelling (PL–SEM) method. The residential loans as a mediator have been used to know the mediation effect between commercial and total real estate loans of banks in India. The residential loans as a mediator govern the relationship between commercial loans and total real estate loans in India. Real estate sector development is a lucrative opportunity for India. The real estate sector plays a major role in shaping economic conditions of the individuals, firms and family.

Design/methodology/approach

The research is descriptive in nature. The study on residential loans, commercial loans and total real estate loans has been taken into consideration, and on the other hand the measurement and structural model have been employed to the study the impact of residential loans and commercial loans on total real estate loans in India by using PL–SEM. The residential loans as a mediator have been taken to study the mediation effect of the relationship between commercial loans and total real estate loans in India.

Findings

The outcome of the structural model that is bootstrapping technique shows that there is an impact of residential and commercial loans by public and private sector banks on total real estate sector development in India. The residential loans show the full mediation effect between commercial loans and total real estate loans as the value of variation accounted for (VAF) is more than 1.93 which shows residential loans govern the nature of variable between commercial loans and total real estate loans.

Practical implications

The public and private sector banks are contributing to the real estate sector development in India which increases the economic growth of the country. The mediation analysis shows that residential loans are an important aspect between commercial and total real estate loans in India as the demand for residential housing is more in India. The increasing role of banks in the real estate sector strengthens the financial capability in the real estate sector market, and the property buyers will able to purchase more property which leads to increasing demand for real estate sector.

Originality/value

The research paper is original, and PL–SEM has been used to find the results.
Systemic conversations across children and young people’s mental health services: a case study
Authors: Clarke Tim , Mihill Tonia
Published: June 2019

Purpose

Improving and transforming children and young people’s (CYP) mental health (MH) services is increasing in importance. Such systems, however, are often delivered across providers and commissioned in different ways which can lead to fragmentation and complexity, ultimately impacting negatively on how young people access services. With increased demand, this means that services are more likely to operate in silos when indeed they should be better integrated. Developing systemic interventions for service leaders and commissioners may support improved integration. The paper aims to discuss this issue.

Design/methodology/approach

Systemic issues across a CYP MH system were assessed and formulated. As a result, using systemic theory, appreciative inquiry and organisational change theories, a “systemic conversation” intervention was developed and delivered to senior leaders and commissioners of this system. This intervention comprised three workshop style sessions with numerous tasks.

Findings

Qualitative feedback and scores in the improvement of important elements that the conversations targeted were collected and examined descriptively. Participants rated their perceived improvement in relationships, transparency, integration, helpfulness and shared vision for future development.

Practical implications

In transforming CYP MH services, this paper considers how the authors can intervene across organisations representing the system to further integrate and improve care for those accessing services.

Originality/value

The intervention described is an original way of intervening with provider representatives from across the system. The paper provides a blueprint of how this might be adopted by others.
Educators’ perceptions of technology integration into the classroom: a descriptive case study
Authors: Hartman Rita J. , Townsend Mary B. , Jackson Marlo
Published: June 2019

Purpose

The purpose of this paper is to supply an in-depth description of the educators’ values, beliefs and confidence changing from a traditional learning environment to a learning environment integrating technology.

Design/methodology/approach

The descriptive case study design was employed using descriptive statistical analysis and inductive analysis on the data collected.

Findings

Themes on a high level of confidence, the importance of professional development and training, self-motivation, and excitement about the way technology can enhance the learning, along with concerns over the lack of infrastructure and support for integrating technology, and about the ability of students to use the technology tools for higher ordered thinking surfaced.

Research limitations/implications

Additional research may include a more diverse population, including educators at the kindergarten to high school level. Another recommendation would be to repeat the study with a population not as vested in technology.

Practical implications

A pre-assessment of the existing values, beliefs and confidence of educators involved in the change process will provide invaluable information for stakeholders on techniques and strategies vital to a successful transition.

Social implications

To effectively meet the learning styles of Generation Z and those students following, educators need be able to adapt to quickly changing technology, be comfortable with students who multitask and be open to technology-rich teaching and learning environments.

Originality/value

This study filled a gap in the literature where little information on the humanistic challenges educators encounter when integrating technology into their learning environment providing insights into the values, beliefs and level of confidence of educators experiencing change.
A video-based assessment of likeability and usability in a play application of robots for children
Authors: Lupetti Maria Luce , Norese Maria Franca , Wu Xiaolu , Mi Haipeng
Published: June 2019

Purpose

The purpose of this paper is to conduct research with children, who have different abilities from adults, in terms of language understanding and level of attention, is a challenging task, especially concerning novel interactive systems such as social robots. Consequently, self-reporting methods are often replaced or supplemented by observational methods that are usually carried out taking advantage of video recordings. However, some limitations make this approach challenging for studies conducted with groups of children in real-world environments, whose relevance is being addressed more and more frequently in human-robot interaction (HRI) research. Thus, there is a growing need for rigorous observation approaches in unstructured test environments.

Design/methodology/approach

This paper presents an alternative analysis approach, in relation to an experimental child-robot interaction (CRI) application, which was developed at the Academy of Arts and Design, Tsinghua University, China. The proposed methodology is based on the analysis of video recordings of in-wild activities of children with a robot. The methodology has the aim of providing a framework to facilitate knowledge identification and structuring. It was implemented for experiment evaluation and validation purposes and to propose a reference structure for the organization of new experiments and the stimulation of new ideas and activities in the design process.

Findings

This methodology provides a logical structure, which can be used to identify the effectiveness or limits of design choices, pertaining to such aspects as the morphology or movement of robots or the choice of their specific role in education, all of which play crucial roles in the design process and could be improved to achieve better results. This structured identification is a practical implication for the design process, above all when it is oriented toward social robots and their interaction with children or elderly senile people. In this case, the outcomes were the identification of important elements of an experiment (psychological profiles of the involved children and possible problems or risks) and their impact on the design process.

Originality/value

The methodological approach, which structures and uses cognitive maps to elaborate multicriteria evaluation models, is not new to the operations research field (where it is defined as a multimethodology application of Soft OR), but it has not yet been applied in the field of HRI studies, to analyze children’s perception of a robot and to identify the factors that can affect a good CRI or to structure knowledge that can be shared to guide the design process of robots for the experience of children playing.
