Published: July 2019

Axonal sorting, the controlled passage of specific cargoes from the cell soma into the axon compartment, is critical for establishing and maintaining the polarity of mature neurons. To delineate axonal sorting events, we took advantage of two neuroinvasive alpha-herpesviruses. Human herpes simplex virus 1 (HSV-1) and pseudorabies virus of swine (PRV; suid herpesvirus 1) have evolved as robust cargo of axonal sorting and transport mechanisms. For efficient axonal sorting and subsequent egress from axons and presynaptic termini, progeny capsids depend on three viral membrane proteins (Us7 (gI), Us8 (gE), and Us9), which engage axon-directed kinesin motors. We present evidence that Us7-9 of the veterinary pathogen pseudorabies virus (PRV) form a tripartite complex to recruit Kif1a, a kinesin-3 motor. Based on multi-channel super-resolution and live TIRF microscopy, complex formation and motor recruitment occurs at the trans-Golgi network. Subsequently, progeny virus particles enter axons as enveloped capsids in a transport vesicle. Artificial recruitment of Kif1a using a drug-inducible heterodimerization system was sufficient to rescue axonal sorting and anterograde spread of PRV mutants devoid of Us7-9. Importantly, biophysical evidence suggests that Us9 is able to increase the velocity of Kif1a, a previously undescribed phenomenon. In addition to elucidating mechanisms governing axonal sorting, our results provide further insight into the composition of neuronal transport systems used by alpha-herpesviruses, which will be critical for both inhibiting the spread of infection and the safety of herpesvirus-based oncolytic therapies.

Author Summary

Alpha-herpesviruses represent a group of large, enveloped DNA viruses that are capable to establish a quiescent (also called latent) but reactivatable form of infection in the peripheral nervous system of their hosts. Following reactivation of latent genomes, virus progeny are formed in the soma of neuronal cells and depend on sorting into the axon for anterograde spread of infection to mucosal sites and potentially new host. We studied two alpha-herpesviruses (the veterinary pathogen pseudorabies virus (PRV) and human herpes simplex virus 1 (HSV-1)) and found viral membrane proteins Us7, Us8, and Us9 to form a complex, which is able to recruit kinsin-3 motors. Motor recruitment facilitates axonal sorting and subsequent transport to distal egress sites. Complex formation occurs at the trans-Golgi network and mediates efficiency of axonal sorting and motility characteristics of egressing capsids. We also used an artificial kinesin-3 recruitment system, which allows controlled induction of axonal sorting and transport for virus mutants lacking Us7, Us8, and Us9. Overall, these data contribute to our understanding of anterograde alpha-herpesvirus spread and kinesin-mediated sorting of vesicular axonal cargoes.

Cancer immunoediting shapes tumor progression by the selection of tumor cell variants that can evade immune recognition. Given the immune evasion and intra-tumor heterogeneity intrinsic to gliomas, we hypothesized that CD8+ T-cells mediate immunoediting in these tumors. We evaluated glioma progression in the absence of CD8+ T-cells by depleting this immune cell population in transgenic murine gliomas. Upon transplantation, gliomas that developed in the absence of CD8+ T-cells engrafted poorly in recipients with intact immunity but engrafted well in those with CD8+ T-cell depletion. Gliomas developed in absence of CD8+ T-cells exhibited increased chromosomal instability, MAPK signaling, gene fusions, and macrophage/microglial infiltration. MAPK activation correlated with macrophage/microglial recruitment in this model and in the human disease. Our results indicate that CD8+ T-cells mediate immunoediting during gliomagenesis, influencing the genomic stability of glioma and its microenvironment, leading to immune evasion.

Significance

Immune evasion renders cancer resistant to anti-tumoral immunity. Therapeutic intervention often fails for gliomas because of the plasticity of tumor cell variants that resist immune surveillance. Our results demonstrate a mechanism of immune evasion in gliomas that derives from CD8+ T-cells during the development and progression of this disease.
Crystal structure of the inhibitor-free form of the serine protease kallikrein-4
Authors: Riley Blake T. , Hoke David E. , McGowan Sheena , Buckle Ashley M.
Published: July 2019

Kallikrein 4 (KLK4) is a serine protease that is predominantly expressed in the prostate and is overexpressed in prostate cancer. As such, it has gained attention as an attractive target for prostate cancer therapeutics. Currently, only liganded structures of KLK4 exist in the Protein Data Bank. Until now, inferences about the subtle structural changes in KLK4 upon ligand binding have been made by comparison to other liganded forms, rather than to an apo form. In this study, an inhibitor-free form of KLK4 was crystallized. The crystals obtained belonged to space group P1, contained four molecules in the asymmetric unit and diffracted to 1.64 Å resolution. Interestingly, a nonstandard rotamer of the specificity-determining residue Asp189 was observed in all chains. This model will provide a useful unliganded structure for the future structure-guided design of KLK4 inhibitors.

Derivation of knockdown factors for grid-stiffened cylinders considering various shell thickness ratios
Authors: Sim Chang-Hoon , Kim Han-Il , Park Jae-Sang , Lee Keejoo
Published: July 2019

Purpose

The purpose of this paper is to derive knockdown factor functions in terms of a shell thickness ratio (i.e. the ratio of radius to thickness) for conventional orthogrid and hybrid-grid stiffened cylinders for the lightweight design of space launch vehicles.

Design/methodology/approach

The shell knockdown factors of grid-stiffened cylinders under axial compressive loads are derived numerically considering various shell thickness ratios. Two grid systems using stiffeners – conventional orthogrid and hybrid-grid systems – are used for the grid-stiffened cylinders. The hybrid-grid stiffened cylinder uses major and minor stiffeners having two different cross-sectional areas. For modeling grid-stiffened cylinders with various thickness ratios, the effective thickness (teff) of the cylinders is kept constant, and the radius of the cylinder is varied. Thickness ratios of 100, 192 and 300 are considered for the orthogrid stiffened cylinder, and 100, 160, 200 and 300 for the hybrid-grid stiffened cylinder. Postbuckling analyses of grid-stiffened cylinders are conducted using a commercial nonlinear finite element analysis code, ABAQUS, to derive the shell knockdown factor. The single perturbation load approach is applied to represent the geometrical initial imperfection of a cylinder. Knockdown factors are derived for both the conventional orthogrid and hybrid-grid stiffened cylinders for different shell thickness ratios. Knockdown factor functions in terms of shell thickness ratio are obtained by curve fitting with the derived shell knockdown factors for the two grid-stiffened cylinders.

Findings

For the two grid-stiffened cylinders, the derived shell knockdown factors are all higher than the previous NASA’s shell knockdown factors for various shell thickness ratios, ranging from 100 to 400. Therefore, the shell knockdown factors derived in this study may facilitate in the development of lightweight structures of space launch vehicles from the aspect of buckling design. For different shell thickness ratios of up to 500, the knockdown factor of the hybrid-grid stiffened cylinder is higher than that of the conventional orthogrid stiffened cylinder. Therefore, it is concluded that the hybrid-grid stiffened cylinder is more efficient than the conventional orthogrid-stiffened cylinder from the perspective of buckling design.

Practical implications

The obtained knockdown factor functions may provide the design criteria for lightweight cylindrical structures of space launch vehicles.

Originality/value

Derivation of shell knockdown factors of hybrid-grid stiffened cylinders considering various shell thickness ratios is attempted for the first time in this study.
Climbing the down escalator
Authors: Johnson Devon , Limbu Yam B. , Jayachandran C. , Reddy P. Raghunadha
Published: July 2019

Purpose

This paper aims to examine the effect of customer-to-customer (C2C) interaction while using a service on the willingness of consumers to engage in altruistic customer participation (CP) or co-production efforts aimed at helping other customers. It further examines the role of consumer skepticism toward the service category in moderating the effects of C2C interaction on altruistic CP and customer satisfaction.

Design/methodology/approach

A survey methodology was used to collect data from 374 consumers of health-care services in India. The data collection involved interviews of patients visiting diabetes clinics and focused primarily on the interaction between customers and their willingness to participate in educating members of the community on diabetic self-care.

Findings

The analysis shows that C2C interaction positively affects customer satisfaction and willingness to engage in altruistic CP. Consumer category skepticism does not moderate the effect of C2C interaction on customer willingness to engage in altruistic CP. However, category skepticism does have the moderating effect of significantly reducing the positive effect of C2C interaction on customer satisfaction.

Research limitations/implications

Data for this study were collected via interviews of consumers in India. Each consumer was interviewed by a trained interviewer. Although the authors do not detect any systematic influence in the results, the possibility of bias is acknowledged. Regarding the research implications, the finding that category skepticism does not moderate the effect of C2C interaction on willingness to engage in altruistic CP suggest that ultimately consumers may have stronger commitment and loyalty to themselves and that their relationships with the firm’s might be peripheral.

Practical implications

The study finds that consumer skepticism toward a service category can have adverse effects for service co-creation. The authors advise managers in troubled industries not to focus exclusively on improving brand differentiation but to also consider working with major industry players and regulators to address the deepest fears of consumers.

Originality/value

The findings have implications for the service dominant logic of marketing in that it suggests that category skepticism is disruptive to the value integration process on which service co-creation relies for value creation. This has strong implications for how managers should structure their interaction processes with customers and for future research that seeks to them prove customer productivity.
Coaching the ‘ideal worker’: female leaders and the gendered self in a global corporation
Authors: Gray David , De Haan Erik , Bonneywell Sally
Published: July 2019

Purpose

Gender differences in leadership and issues around differential progression of male and female leaders are receiving more attention in the fields of human resource and leadership development. However, little is known about how interventions designed to support female leaders are being experienced within real-world contexts of global organizations. There is limited research and discussion on how such interventions are experienced at a more systemic level. This study aims to contribute at this very level.

Design/methodology/approach

This study reports on a predominantly coaching-based development program that was designed to further the careers of female leaders within a complex multi-national organization. The study was conducted in a large, global health-care corporation employing 100,000 people based in over 120 countries. The qualitative research design for this study was exploratory, involving a reflexive process at each of the two stages.

Findings

The findings from this qualitative research take the debate on “the gendered organization” further by including the voices of female leaders. They demonstrate that whilst theoretically the concept of the “ideal worker” may inhibit progression, this is not necessarily a barrier to career advancement. Coaching, both individual and group, is shown to have a powerful effect on promoting reflection, self-confidence and focus.

Research limitations/implications

There are two research limitations. While confidentiality was promised, the responses of some interviewees were nevertheless still guarded. Other limitations relate to the extent to which this study can be generalized to other contexts, as it was conducted inside a single global corporation.

Originality/value

The study addresses the complex and urgent topic of differential progression and makes a broader contribution by offering a systemic perspective on gender and development in global organizations.
Mapping talent development in tourism and hospitality: a literature review
Authors: Johnson Karen R. , Huang Taiyi , Doyle Alaina
Published: July 2019

Purpose

The purpose of this study is to develop a deeper understanding of the scope of talent development (TD) strategies and practices in tourism and hospitality industry contexts.

Design/methodology/approach

Because the literature on talent management and TD in tourism and hospitality is limited and fragmented, an integrative literature review method was used to identify and analyze relevant studies to create a more comprehensive representation of the industry’s talent strategies.

Findings

Findings from the literature review showed that by nature, the context of tourism and hospitality is complex and the meaning of talent in this industry is not necessarily comparable to other industry sectors (Baum, 2008). While most industries adopt a more exclusive approach to develop talent, an inclusive approach may be more ideal for tourism and hospitality especially in light of the importance of frontline employees for business success. More robust management structures and human resource systems are needed especially in small and medium tourism enterprises to aid the facilitation of TD. A partnership approach involving strong commitment between education, industry and government should be necessitated to implement and sustain TD considering the importance of the industry to nation’s economic and social advancement.

Research limitations/implications

This study adds to the body of literature on TD in tourism and hospitality. Future research opportunities should explore both qualitative and quantitative methods to provide empirical evidence and to further build on the literature.

Practical implications

Generally, organizations place emphasis on the development of technical skills, however, managers and leaders of tourism organizations should focus on developing both technical and generic competencies especially for frontline employees to ensure that a positive image of the organization is consistently demonstrated. TD can influence employees’ emotional labor; therefore, increased and quality emotional labor training can impact the types of strategies that employees use during guest encounters to promote quality service.

Originality/value

The paper contributes a comprehensive review of the literature on TD in the tourism and hospitality context. The TD map provides more focused direction and will aid in the establishment of TD strategies and practices.
Economics of human resources development under globalization era: a study of BRICS countries
Authors: Hassan Samir Ul , Rymbai Motika Sinha , Bhat Aasif Ali
Published: July 2019

Purpose

The study aims to explore the extent to which human resources development quantifies the economic growth of BRICS countries under the globalization era by controlling country differences.

Design/methodology/approach

The study used the Generalized Method of Moments (GMM) and Scheffe pairwise comparison tests to quantify the impact of the variables and the level of difference among the BRICS countries onto human Resources development.

Findings

The study observes that the impact of human resources development on economic growth of BRICS counties is significant but limited to few countries. The study reveals that countries such as India and South Africa are unable to utilize their human resources efficiently to promote economic growth, as compared with Russia, China and Brazil. The study further argues that there is urgent need of amalgam of various economic development theories keeping in mind the regional needs to extract the positive impact from human resource on economic development.

Research limitations/implications

The single limitation of this research is that it was not possible to compare the results with other developing countries to unleash the capabilities of human resources development with regard to economic growth at the universal level.

Originality/value

To the best of the authors’ knowledge, this paper is the first of its kind to analyze human resources development at a much deeper level. The paper has chosen variables which are important from the policy perspective of government rather than the working perspective, which is a great contribution. Further, for human index the variables chose covering major aspects of human development from spending perspective.
Industrial standardisation as a driver for cross-national convergence in training processes
Authors: Lahiff Ann , Li Junmin , Unwin Lorna , Zenner-Höffkes Lea , Pilz Matthias
Published: July 2019

Purpose

The purpose of this paper is to address a gap in the comparative research literature on vocational education and training (VET) and skill formation systems. It examines the impact of international technical standardisation and regulation on the design, organisation and delivery of apprenticeships in the aeronautical and aerospace sectors in England and Germany.

Design/methodology/approach

The research design was informed by insights from economics, workplace and work-based learning and comparative education. Academic experts in the fields of aerospace and aeronautical standardisation and regulation, VET, human resource development and business organisation were consulted. The generic occupation of “aircraft mechanic” was selected as being the closest match for comparison. Interviews and non-participant observation in workplaces and training centres were carried out involving three companies in England and four in Germany.

Findings

Findings show that there is considerable convergence across the pedagogical approaches to apprenticeships in England and Germany related to fostering the capacity to take responsibility for the quality of one’s work, to work in and lead teams, and to respond to and work with customers. Increasing international regulation and technical standardisation underpins a shared language about learning through practice in technologically advanced workplaces.

Originality/value

This paper is original because it turns the lens of inquiry to workplace processes to reveal the level of convergence in training philosophies and practices in an internationally highly regulated sector. It shows how international technical standardisation and regulation is leading to pedagogical innovation. The findings have implications for VET and apprenticeship policy at the national and international level.
Analysis of tilted neutral planes for tall space fires with unsymmetrical openings using numerical simulation and Schlieren photography technique
Authors: Su ChungHwei , Wang ShiuanCheng
Published: July 2019

Purpose

The purpose of this paper is to analyze the variations in the neutral plane when a tall space with unsymmetrical openings is on fire. The neutral plane of the fire scene is an important index of a natural smoke exhaust system. The numerical simulation method and the Schlieren photography technique were used as analysis tools. The results of model experiments and numerical simulation were compared with each other to confirm the rationality of the conclusions. The results were to discuss the characteristics of various cases and showed that the neutral planes of the fire scene were not always horizontal.

Design/methodology/approach

The numerical simulation method and the Schlieren photography technique were used as analysis tools. The flow patterns of hot air in various cases were recorded using the flow visualization technique. In addition, the renowned simulation software, fire dynamics simulator (FDS), was used for case analysis. The Schlieren photography technique was used for 1/12.5 model experiments with six smokeless candles burned, and FDS was used for a numerical simulation. In terms of the case of unilateral vents, the exhaust efficiency was discussed when the exhaust vent and air inlet were located on the same side or different sides.

Findings

This study demonstrates that makeup air flowing in from the inlets and openings has a significant impact on the effectiveness of natural smoke exhaust systems. The results illustrated that the neutral planes were tilted in some cases. In some cases, the results showed that one side was the air inlet and the other side was the exhaust vent, even if the openings were at the same height in some cases. These phenomena have rarely been discovered or studied in the past. The exhaust efficiency was not always better when the vent was located in the rooftop.

Originality/value

This study analyzed the neutral plane of a fire scene using the common unsymmetrical opening spaces in the Taiwan region as an example. The phenomenon of non-horizontal neutral plane has rarely been studied in the past. The temperature of the discharged hot gas was low because of an efficient exhaust effect, which reduced the heat and smoke storage in the space. The results obtained by these two methods were consistent, and showed that the cases with the same opening area had different smoke extraction efficiencies, meaning the smoke extraction effect cannot be judged only by the opening areas.

Authors: Xiong Qingang , Khosravi Arash , Nabipour Narjes , Doranehgard Mohammad Hossein , Sabaghmoghadam Aida , Ross David
Published: July 2019

Purpose

This paper aims to numerically investigate the nanofluid flow, heat transfer and entropy generation during natural convection in an annulus.

Design/methodology/approach

The lattice Boltzmann method is used to simulate the velocity and temperature fields. Furthermore, some special modifications are applied to make the lattice Boltzmann method capable for simulation in the curved boundary conditions. The annulus is filled with CuO-water nanofluid. The dynamic viscosity of nanofluid is estimated using KLL (Koo-Kleinstreuer-Li) model, and the nanoparticle shape effect is taken account in calculating the thermal conductivity. On the other hand, the local/volumetric entropy generation is used to show the irreversibility under influence of different parameters.

Findings

The effect of considered governing parameters including Rayleigh number (103<Ra < 106); nanoparticle concentration (0<<0.04) and configuration of annulus on the flow structure; temperature field; and local and total entropy generation and heat transfer rate are presented.

Originality/value

The originality of this work is using of lattice Boltzmann method is simulation of natural convection in a curved configuration and using of Koo–Kleinstreuer–Li correlation for simulation of nanofluid.
GCRO with dynamic deflated restarting for solving adjoint systems of equations for aerodynamic shape optimization
Authors: Chen Chih-Hao , Nadarajah Siva
Published: July 2019

Purpose

This paper aims to present a dynamically adjusted deflated restarting procedure for the generalized conjugate residual method with an inner orthogonalization (GCRO) method.

Design/methodology/approach

The proposed method uses a GCR solver for the outer iteration and the generalized minimal residual (GMRES) with deflated restarting in the inner iteration. Approximate eigenpairs are evaluated at the end of each inner GMRES restart cycle. The approach determines the number of vectors to be deflated from the spectrum based on the number of negative Ritz values, k∗.

Findings

The authors show that the approach restores convergence to cases where GMRES with restart failed and compare the approach against standard GMRES with restarts and deflated restarting. Efficiency is demonstrated for a 2D NACA 0012 airfoil and a 3D common research model wing. In addition, numerical experiments confirm the scalability of the solver.

Originality/value

This paper proposes an extension of dynamic deflated restarting into the traditional GCRO method to improve convergence performance with a significant reduction in the memory usage. The novel deflation strategy involves selecting the number of deflated vectors per restart cycle based on the number of negative harmonic Ritz eigenpairs and defaulting to standard restarted GMRES within the inner loop if none, and restricts the deflated vectors to the smallest eigenvalues present in the modified Hessenberg matrix.
The prediction role of feeling of injustice on network social mobilization
Authors: Zhang Jinghuan , Wang Shan , Zheng Wenfeng , Wang Lei
Published: July 2019

Purpose

By drawing on the research paradigm of collective action that occurs in physical space, the present study aims to explore the antecedent predictors of network social mobilization – feeling of injustice – and discuss the emotional mechanism of this prediction: mediating effect of anger and resentment.

Design/methodology/approach

Micro-blog postings about network social mobilization were collected to develop the dictionary of codes of fairness, anger and resentment. Then, according to the dictionary, postings on Sina Weibo were coded and analyzed.

Findings

The feeling of injustice predicted network social mobilization directly. The predictive value was 27% and 33%, respectively during two analyses. The feeling of injustice also predicted social mobilization indirectly via anger and resentment. In other words, anger and resentment account for the active mechanism in which the feeling of injustice predicts network social mobilization. Mediating effect value was 29.63% and 33.33% respectively.

Research limitations/implications

This study is our first exploration to use python language to collect data from human natural language pointing on micro-blog, a large number of comments of netizen about certain topic were crawled, but a small portion of the comments could be coded into analyzable data, which results in a doubt of the reliability of the study. Therefore, we should put the established model under further testing.

Practical implications

In the cyberspace, this study confirms the mechanism of network social mobilization, expands and enriches the research on social mobilization and deepens the understanding of social mobilization.

Social implications

This study provides an empirical evidence to understand the network social mobilization, and it gives us the clue to control the process of network social mobilization.

Originality/value

This study uses the Python language to write Web crawlers to obtain microblog data and analyze the microblog content for word segmentation and matching thesaurus. It has certain innovation.

Authors: Song Zhigang , Gu Qinxuan , Wang Boyi
Published: July 2019

Purpose

The purpose of this paper is to develop a measurement of creativity-oriented HRM systems that improve organizational creativity. This paper also aims to explore the mechanisms between them by investigating the mediating role of innovative culture and the moderating role of customer orientation.

Design/methodology/approach

The study uses a sample of 82 knowledge-intensive companies with 780 respondents consisting of 145 HR professionals, 512 core knowledge workers and 123 top managers in China. Exploratory factor analysis, confirmatory factor analysis and regression analysis are used to validate the measure of creativity-oriented HRM systems and test hypotheses.

Findings

This study finds that creativity-oriented HRM systems are composed of three dimensions, which are creative skill-enhancing practices, intrinsic motivation-enhancing practices and empowerment-enhancing practices. These practices significantly improve organizational creativity through innovative culture. Furthermore, customer orientation moderates the effect of innovative culture on organizational creativity in such a way that the positive relationship is stronger when customer orientation is high.

Originality/value

This study contributes to the strategic human resource management literature by developing and validating a measure of creativity-oriented HRM systems. Moreover, it also explores the mechanism between creativity-oriented HRM systems and organizational creativity based on a complementary perspective of innovativeness, which underlines the important mediating effect of innovative culture.

Exploring the impact of perceived AMO framework on constructive and destructive deviance
Authors: Malik Pooja , Lenka Usha
Published: July 2019

Purpose

The purpose of this paper is to investigate the impact of perceived abilities-motivation-opportunity (AMO framework) enhancing human resource management practices on destructive and constructive deviance through employee engagement.

Design/methodology/approach

Data were collected from 350 middle-level information technology employees. Structural equation modeling was applied to examine the proposed hypotheses.

Findings

Results revealed significant relationships between perceived AMO framework and destructive and constructive deviance, except for the relationship between perceived ability and destructive deviance. Furthermore, perceived AMO framework exhibited a significant positive relationship with employee engagement. Utilizing social exchange theory, results proposed partial mediation of employee engagement between perceived AMO framework and constructive and destructive deviance except for the relationship between perceived ability and destructive deviance, for which employee engagement exhibited full mediation.

Research limitations/implications

This study implies that contemporary organizations must take initiatives to enhance employee engagement through the implementation of abilities, motivation and opportunities-enhancing human resource management (HRM) practices (AMO framework). Results of the study infer that motivation-enhancing HRM practices contribute highest in generating employee engagement followed by opportunity and abilities-enhancing HRM practices.

Originality/value

This study empirically investigates the impact of HRM bundles on both destructive and constructive deviance. Additionally, this study explores the underlying mechanism between HRM bundles and workplace deviance by assessing the mediating role of employee engagement.
The brand is my workplace
Authors: Bareket-Bojmel Liad , Shuv-Ami Avichai
Published: July 2019

Purpose

The purpose of this paper is to adapt the well-established concept of “brand equity” in order to define and measure employer branding and its organizational consequences.

Design/methodology/approach

This paper utilized structural equation modeling with a large sample of 600 employees to test the proposition that organizational brand equity (OBE) is translated into attitudes toward the workplace (organizational commitment) and has possible behavioral consequences (turnover intentions).

Findings

The study findings provide support for a partial mediation model. In addition to a direct association between OBE and turnover intentions, organizational commitment mediates the relationships between OBE and turnover intentions within a 12-month period.

Originality/value

Employer branding research is heterogeneous in terms of measurement tools and scope. This paper is part of an emerging perspective that suggests the adoption of the brand equity concept from marketing into the field of OB. This paper investigates the relationships between brand equity, employees’ commitment and turnover intentions. Well-established measures and a large-scale sample of 602 participants are used.
Regional entrepreneurial ecosystems in Mexico: a comparative analysis
Authors: Villegas Mateos Allan Oswaldo , Amorós José Ernesto
Published: July 2019

Purpose

The entrepreneurial ecosystem approach tries to understand the mechanisms underlying new business creation and helps develop tools, governmental policies and support systems that enhance the outcomes of entrepreneurship activities. To ensure a better understanding of those mechanisms, this study aims to contrast regional policies in emerging economies that are designed to foster local new business creation and development.

Design/methodology/approach

One of the Global Entrepreneurship Monitor’s surveys, the National Experts’ Survey, was applied to a sample of N = 675 key informants in Mexico at ten entities, seven of whom were categorized as non-centrally located. The authors used non-parametric statistics to compare the differences between centrally and non-centrally located experts.

Findings

The main results indicate that non-centrally located experts perceive their regions to be in a worse position than centrally located experts in terms of government policies regulation, post-school education and commercial and physical infrastructure, but surprisingly in a better position regarding financial access, general government policy, government programs, primary and secondary education, R&D transfer, market dynamism and openness and cultural and social norms.

Practical implications

These findings have policy implications for all levels of government in Mexico, which must prioritize the homologation of opportunities for people in both large and small cities.

Originality/value

The replication of a Chilean study contributes to the empirical literature of regional entrepreneurial ecosystems in emerging economies.
Embodying engineering leadership
Authors: Florez Wilson Antonio
Published: July 2019

Purpose

Accrediting boards and employers agree that there is a growing need for engineering leadership training. The aforementioned recognized, soft skills training is still an incipient initiative in the engineering discipline. This paper aims to summarize the implementation of the Engineering Leadership Program at the School of Engineering, where the implementation process uses the model for learning and teaching proposed by Reyes and Zarama, 1998b, as a strategy to embody engineering leadership capabilities. The best practices in regard to the capabilities that promote engineering leadership are discussed. The final remarks highlight the relevance of the active student roles in the development of the Engineering Leadership Program.

Design/methodology/approach

The author describes the implementation of the Engineering Leadership Program using Reyes and Zarama’s process of embodying distinctions.

Findings

The use of systemic models for teaching and learning in the implementation of Engineering Leadership Programs helps facilitate leadership competencies in students. The implementation of “engineering leadership” as complementary activity in the engineering curriculum demonstrated individual and program advantages – in comparison to solely modifying the current engineering curriculum.

Originality/value

This work enhances the understanding of how engineering schools can design activities to promote engineering leadership in former engineers as is requested by international accreditation boards and by engineering employers.
How label and nutritional claims affect consumers’ acceptance, buying intention and quality perception toward a beverage made from cashew nut
Authors: Rebouças Marina Cabral , Rodrigues Maria do Carmo Passos , Freitas Silvia Maria de
Published: July 2019

Purpose

The purpose of this paper is to evaluate the influence of the front of a package label and the nutritional claims linked to it over consumers’ expectations as to acceptance, purchase attitude and perception of quality characteristics of a new functional beverage made from cashew nut milk and added with mango juice and prebiotic substances.

Design/methodology/approach

Three versions of the front label were developed, which differed just by the type of nutritional claim presented (“0 per cent lactose and 0 per cent cholesterol; 0 per cent lactose, 0 per cent cholesterol and source of fibers, 0 per cent lactose, 0 per cent cholesterol and antioxidants”) and were evaluated in two phases, expectation and informed. For the evaluation, consumers used a multi-attribute scale, the nine-point hedonic scale and a nine-point semi-structured buying attitude scale.

Findings

The labels created a positive expectation on the consumers regarding the quality attributes, overall impression (mean = 6.0 “Like slightly”) and buying attitude (mean = 6.0 “Would probably buy”). After tasting the beverage associated with labels (informed phase), consumers kept a positive evaluation. The t-test performed between the pair of means of both phases showed that there has not been a significant difference regarding the quality attributes (p > 0.05), special, attractive, nutritive, healthy and buying attitude (Label 1, p = 0.26; Label 2, p = 0.18; Label 3, p = 0.26) in all labels.

Originality/value

The authors evaluated how the influence of label and nutritional claims in regards to a new product, a beverage made from cashew nut, affects its acceptance, buying attitude and characteristics of quality. Until this moment, there are no studies that evaluate how external attributes affect the acceptance of this beverage totally unique in the Brazilian market.
Self-cleaning treatment on historical stone surface via titanium dioxide nanocoatings
Authors: Kardar Pooneh , Amini Reza
Published: July 2019

Purpose

The purpose of this study is to evaluate the possibility of using titanium dioxide coating in the field of architectural heritage.

Design/methodology/approach

In this research, a titanium dioxide coating was prepared and then applied to the travertine stone surfaces. The nature of the coating was determined through various observations and analyses. Moreover, the effect of photocatalytic self-cleaning was evaluated using an organic dye (Rhodamine B).

Findings

The results of XRD, DLS and SEM confirmed the formation of small anatase crystals. The hydrophilic behavior on the surface was observed by coatings based on titanium dioxide.

Research limitations/implications

The self-cleaning ability of titanium dioxide is due to the synergistic effect of its optical inductive property, which is activated with sunlight.

Practical implications

The self-cleaning coatings are interested for many industries. The reported data can be used by the formulators working in the research and development departments.

Social implications

Self-cleaning systems are considered as smart coatings. Therefore, the developing of its knowledge can help to extend its usage to different applications.

Originality/value

The application of titanium dioxide coating in the field of architectural heritage is a great challenge. Therefore, in this research, a titanium dioxide coating was prepared by sol-gel method and then applied on travertine surfaces and its properties were studied.
The purpose and impact of postgraduate knowledge
Authors: Wisker Gina , Robinson Gillian Diana , Leibowitz Brenda
Published: July 2019

Purpose

Much research into outcomes of doctoral learning focuses on employability, or the dearth of academic employment in relation to doctoral graduate expectations, emphasising precarity of academic future work. This new work begins with and moves beyond employment issues, highlighting professional practice and personal knowledge development and impact.

Design/methodology/approach

Much doctoral education research focuses on the academic identities of postgraduates, their change and alignment to the work and experience of being a doctoral student and beyond, in academic or other jobs. This longitudinal work explores professional and social impact from doctoral research and transformational changes experienced and reported by graduates in two projects. Based on narrative interviewing turned into case studies, it asks fundamental questions about the purpose and impact of postgraduate knowledge.

Findings

Respondents emphasised change in their sense of personal, academic and professional identity; immediate impact on professional practice leading to job change, status, changes in practices and longer-term impacts of further influences on professional practice, some international in reach.

Research limitations/implications

This small-scale study has widespread implications for understanding the impact of postgraduate knowledge on professional practice and personal development.

Practical implications

The work could influence doctoral student intentions and the focus of doctoral programmes.

Social implications

Postgraduate knowledge is seen as crucial in theorised and practical contributions to social development.

Originality/value

This longitudinal work generates new knowledge, answering questions: What is the purpose of postgraduate knowledge? Who benefits from results? What is the impact from the research? How are outcomes put into professional practice? It found significant developments in professional practice and personal development.
Exploring undergraduates’ money-management life: insight from an emerging economy
Authors: Sachitra Vilani , Wijesinghe Dinushi , Gunasena Wajira
Published: July 2019

Purpose

Undergraduates are expected to be future leaders responsible for business and nations. Given that sound financial decision-making is critical to their success in their careers and lives, it is important to understand the money-management behaviour of undergraduates. In the context of developing countries, the body of knowledge on money-management behaviour is dominated by functional financial literature and there is little research on factors beyond this. This study aims to fill this gap by exploring economic, social and psychological factors that influence money-management behaviour of undergraduates in a developing nation (Sri Lanka) and how undergraduates respond to these influences.

Design/methodology/approach

The study used a qualitative exploratory approach. Data collection was carried out using focus group discussions and individual interviews amongst undergraduates in a leading Sri Lankan state university.

Findings

The results indicate that undergraduates adopted both careful and risky money-management approaches. The subthemes, specifically identified under economic, social and psychological factors, revealed how undergraduates responded to each of these factors and the influence of contextual and cultural differences in their money-management behaviour.

Research limitations/implications

Findings of the study revealed the importance of promoting innovative educational strategies to change the dependability mindset of undergraduates and to promote stress-management strategies that will assist them to enhance their personalities and creativity in making financial decisions. Theoretical and practical implications and future research directions are provided.

Originality/value

The literature scores in developing context are limited to exploring the existing pattern and the levels of the functional financial literacy. This study has deepened the authors’ understanding of how the developing context affects undergraduates’ response to the factors relating to their money-management behaviour. The findings from this study will be useful to government, financial institutions, educational institutions, parents and those who have a keen interest in encouraging healthy money-management behaviour in undergraduates.
