Authors: Asuru Awuri , Farquhar Erik R. , Sullivan Michael , Abel Donald , Toomey John , Chance Mark R. , Bohon Jen
Published: June 2019

Hydroxyl-radical mediated synchrotron X-ray footprinting (XF) is a powerful solution-state technique in structural biology for the study of macromolecular structure and dynamics of proteins and nucleic acids, with several synchrotron resources available to serve the XF community worldwide. The XFP (Biological X-ray Footprinting) beamline at the NSLS-II was constructed on a three-pole wiggler source at 17-BM to serve as the premier beamline for performing this technique, providing an unparalleled combination of high flux density broadband beam, flexibility in beam morphology, and sample handling capabilities specifically designed for XF experiments. The details of beamline design, beam measurements, and science commissioning results for a standard protein using the two distinct XFP endstations are presented here. XFP took first light in 2016 and is now available for general user operations through peer-reviewed proposals. Currently, beam sizes from 450 µm × 120 µm to 2.7 mm × 2.7 mm (FWHM) are available, with a flux of 1.6 × 1016 photons s−1 (measured at 325 mA ring current) in a broadband (∼5–16 keV) beam. This flux is expected to rise to 2.5 × 1016 photons s−1 at the full NSLS-II design current of 500 mA, providing an incident power density of >500 W mm−2 at full focus.
A variable fixed-focus constant optimization method for a variable-included-angle varied-line-spacing plane-grating monochromator
Authors: Xue Chaofan , Xue Lian , Wu Yanqing , Wang Yong , Yang Shumin , Tai Renzhong
Published: June 2019

Variable-included-angle varied-line-spacing plane-grating monochromators (VIA-VPGM) have been applied to many beamlines because of the self-focusing and aberration-correction function of the varied-line-spacing grating. Unfortunately, to optimize the variable-line-spacing coefficient of the grating, the fixed-focus constant (C
ff) has to be fixed first in the VIA-VPGM. In this way, some of the advantages of these monochromators are lost, such as the flexibility of choosing a different energy-resolving power by varying the C
ff. In this work, a variable C
ff optimization method is introduced for a VIA-VPGM. By adopting this method, the C
ff could be arbitrarily selected in the VIA-VPGM.

Coagulation factor XII (FXII) is a key initiator of the contact pathway, which contributes to inflammatory pathways. FXII circulates as a zymogen, which when auto-activated forms factor XIIa (FXIIa). Here, the production of the recombinant FXIIa protease domain (βFXIIaHis) with yields of ∼1–2 mg per litre of insect-cell culture is reported. A second construct utilized an N-terminal maltose-binding protein (MBP) fusion (MBP-βFXIIaHis). Crystal structures were determined of MBP-βFXIIaHisin complex with the inhibitor D-Phe-Pro-Arg chloromethyl ketone (PPACK) and of βFXIIaHisin isolation. The βFXIIaHisstructure revealed that the S2 and S1 pockets were occupied by Thr and Arg residues, respectively, from an adjacent molecule in the crystal. The Thr-Arg sequence mimics the P2–P1 FXIIa cleavage-site residues present in the natural substrates prekallikrein and FXII, and Pro-Arg (from PPACK) mimics the factor XI cleavage site. A comparison of the βFXIIaHisstructure with the available crystal structure of the zymogen-like FXII protease revealed large conformational changes centred around the S1 pocket and an alternate conformation for the 99-loop, Tyr99 and the S2 pocket. Further comparison with activated protease structures of factors IXa and Xa, which also have the Tyr99 residue, reveals that a more open form of the S2 pocket only occurs in the presence of a substrate mimetic. The FXIIa inhibitors EcTI and infestin-4 have Pro-Arg and Phe-Arg P2–P1 sequences, respectively, and the interactions that these inhibitors make with βFXIIa are also described. These structural studies of βFXIIa provide insight into substrate and inhibitor recognition and establish a scaffold for the structure-guided drug design of novel antithrombotic and anti-inflammatory agents.

Published: June 2019

The title compound, C13H10INO, is not planar as the dihedral angle between the planes of the two aryl rings is 44.5 (9)°. The configuration about the central C=N bond is E, and there is an intramolecular O—H...N hydrogen bond which generates an S(6) ring. The molecular packing is stabilized by weak C—H...π interactions. The structure was refined as a two-component inversion twin.
Multidisciplinary impact – the arts join informal STEM programs
Authors: Tretola Betsy , Coupey Eloise , Meamber Laurie
Published: June 2019

Purpose

Middle school participants in the USA attending an on-campus university informal science program indicate an increase in interest toward careers and disciplines in STEM or STEAM (science, technology, engineering and mathematics and the arts). Parents or guardians confirm the change. The paper aims to discuss this issue.

Design/methodology/approach

Participants attended “inquiry-based” lectures by scientists and “hands-on” activities conducted by volunteers on campus at a public university over four months, four Saturdays. Participants completed surveys before each lecture and guardians completed surveys afterwards.

Findings

Interest increased significantly according to paired samples t-tests for each STEM discipline for students who reported low interest on the initial pre-lecture survey. There was a significant linear improvement in interests in engineering using a repeated measures general linear model. Guardians or parents reported that they observed a higher interest in STEM disciplines resulting in more technical-related interaction among peers and within the family.

Social implications

Findings support STEM with arts “out-of-school” programs sponsored by museums, corporations, government, higher education and others. Inclusion of the “hands-on” activities, some with arts content, to the science and technical learning appears to spark enthusiasm.

Originality/value

The value is multidisciplinary. The theory of reasoned action from social psychology, sociology, along with related research in science education and the arts are synthesized. Informal extracurricular experiences sustained and improved interests in the disciplines and careers on which the formal educational career pipeline can build.
Oil, gold, stones: cultural value in Italian cultural policy
Authors: Borchi Alice
Published: June 2019

Purpose

The purpose of this paper is to understand the concept of cultural value promoted by the Italian government between 2008 and 2018. Furthermore, it aims at setting the scope for further research and debate on the issue of cultural value in Italian cultural policy by questioning market-driven understanding of value.

Design/methodology/approach

In order to do so, it examines the rhetoric of Italian policymakers, with a particular focus on the people who have covered the role of Ministry for Cultural Assets and Activities over this 10-year span, and the policies they have implemented. The various nuances of the concept of valorizzazione are studied by analysing different pathways employed by the Italian government and the values underpinning them, with a particular focus on the abandonment of heritage sites.

Findings

What emerges from this research is the centrality of the economic value of culture; however, the economic impact of Italian cultural assets is always presented as a potential that has to be unlocked by implementing policies of valorizzazione, a term that has a double meaning of promotion and exploitation (Belfiore, 2006).

Originality/value

This paper presents an original approach to understanding the formation and promotion of cultural value at the level of governmental policy in the context of contemporary cultural policy in Italy. In particular, it evidences how the centrality of the economic value of culture has remained unscathed despite the rapid change of governments that has characterised Italian politics in the last 10 years.
The death of arts marketing: a paradigm shift from consumption to enrichment
Authors: Walmsley Ben
Published: June 2019

Purpose

The purpose of this paper is to demonstrate how researchers in the field of arts marketing are gradually abandoning the traditional marketing concept in order to respond to established and emerging modes of audience engagement.

Design/methodology/approach

The study is based on a comprehensive content analysis of the past three decades of journal articles related to arts marketing.

Findings

The results of the content analysis highlight that a paradigm shift in arts marketing has occurred over the past two decades, from an overriding focus on neoliberal processes of consumption towards a relational, humanistic approach, which aims to enrich audiences and interrogate the wider value and impact of their arts experiences.

Research limitations/implications

The logical conclusion to be derived from this paradigmatic shift is that “arts marketing” is increasingly becoming an outmoded misnomer, which suggests the need for a fundamental reassessment of the traditional arts marketing concept.

Practical implications

In order to develop meaningful relationships with audiences, arts and cultural organisations should prioritise the long-term relational approaches offered by audience engagement over short-term tactical activities such as segmentation and promotion.

Originality/value

The paper advocates a radical reconceptualization of the field that would replace the transactional 4P model with a relational 4E model, derived from an adoption of theories, processes and practices related to the elements of experience, exchange, environment and engagement.
Paternalistic leadership and employee well-being: a moderated mediation model
Authors: He Guohua , An Ran , Hewlin Patricia Faison
Published: June 2019

Purpose

This paper aims to explore the psychological mechanism in the relationship between paternalistic leadership (PL) and employee well-being (EWB) in cross-cultural nonprofit organizations. It also aims to further promote the integration of research on PL and self-concept by examining the relationship between PL and collective self-concept (CSC).

Design/methodology/approach

Data were collected on 72 supervisors and 233 expatriate Chinese teachers from 42 Confucius Institutes and 15 Confucius classrooms in Canada and the USA.

Findings

PL has a significant effect on EWB. Benevolent and moral leadership are positively related to CSC, while authoritarian leadership is negatively related to CSC. CSC mediates the relationship between PL and EWB. Furthermore, employees’ cross-cultural adaptability positively moderates the relationship between CSC and EWB; the indirect effect between PL and EWB via CSC is stronger for employees with stronger cross-cultural adaptability.

Originality/value

This is the first study that has examined the psychological mechanism under which PL affects EWB in cross-cultural nonprofit organizations. It contributes to the integration of research on PL and CSC by examining its relationship for the first time. It provides important implications for improving the well-being of expatriate employees in cross-cultural organizations.
Carnegie in Australia: philanthropic power and public education in the early twentieth century
Authors: Green Bill
Published: June 2019

Purpose

The purpose of this paper is to outline a reconceptualised view of public education, with specific reference to early twentieth-century Australia, and to revisit the significance of the Carnegie Corporation of New York in this period. Further, in this regard, the paper proposes a neo-Foucaultian notion of philanthropic power, as an explanatory and analytical principle, with possible implications for thinking anew about the role and influence of American philanthropic organisations in the twentieth century.

Design/methodology/approach

The paper draws on mainly secondary sources but also works with primary sources gathered from relevant archives, including that of the Australian Council for Educational Research (ACER).

Findings

The paper concludes that the larger possibilities associated with the particular view of public education outlined here, referring to both public school and public libraries, were constrained by the emergence and consolidation of an increasingly professionalised view of education and schooling.

Research limitations/implications

The influence of the Carnegie Corporation of New York on early twentieth-century Australian education has been increasingly acknowledged and documented in recent historical research. More recently, Carnegie has been drawn into an interdisciplinary perspective on philanthropy and public culture in Australia. This paper seeks to add to such work by looking at schools and libraries as interconnected yet loosely coupled aspects of what can be understood as, in effect, a re-conceived public education, to a significant degree sponsored by the Corporation.

Originality/value

The paper draws upon but seeks to extend and to some extent re-orient existing historical research on the relationship between Australian education and the Carnegie Corporation of New York. Its originality lies in its exploration of a somewhat different view of public education and the linkage it suggests in this regard with a predominantly print-centric public culture in Australia, in the first half of the twentieth century.
Hybrid nanofluid flow and heat transfer over a nonlinear permeable stretching/shrinking surface
Authors: Waini Iskandar , Ishak Anuar , Pop Ioan
Published: June 2019

Purpose

This paper aims to investigate the steady flow and heat transfer of a Cu-Al2O3/water hybrid nanofluid over a nonlinear permeable stretching/shrinking surface with radiation effects. The surface velocity condition is assumed to be of the power-law form with an exponent of 1/3. The governing equations of the problem are converted into a system of similarity equations by using a similarity transformation.

Design/methodology/approach

The problem is solved numerically using the boundary value problem solver (bvp4c) in Matlab software. The results of the skin friction coefficient and the local Nusselt number as well as the velocity and temperature profiles are presented through graphs and tables for several values of the parameters. The effects of these parameters on the flow and heat transfer characteristics are examined and discussed.

Findings

Results found that dual solutions exist for a certain range of the stretching/shrinking and suction parameters. The increment of the skin friction coefficient and reduction of the local Nusselt number on the shrinking sheet is observed with the increasing of copper (Cu) nanoparticle volume fractions for the upper branch. The skin friction coefficient and the local Nusselt number increase when suction parameter is increased for the upper branch. Meanwhile, the temperature increases in the presence of the radiation parameter for both branches.

Originality/value

The problem of Cu-Al2O3/water hybrid nanofluid flow and heat transfer over a nonlinear permeable stretching/shrinking surface with radiation effects is the important originality of the present study where the dual solutions for the flow reversals are obtained.
Permeability determination in tight rock sample using novel method based on partial slip modelling and X-ray tomography data
Authors: Madejski Paweł , Krakowska Paulina , Puskarczyk Edyta , Habrat Magdalena , Jędrychowski Mariusz
Published: June 2019

Purpose

The purpose of the paper was the application of computational fluid dynamics (CFD) techniques in fluid flow using Maxwell’s equation for partial slip modelling, estimating the flow parameters, and selecting tangential momentum accommodation coefficient (TMAC) for tight rock samples in permeability calculations.

Design/methodology/approach

The paper presents a numerical analysis of fluid flow in a low-porosity rock sample by using CFD. Modelling results allowed to determine mass flow rates in a rock sample and to calculate permeability values using a modified Darcy’s equation. Three-dimensional (3D) geometrical model of rock sample generated using computed X-ray tomography was used in the analysis. Steady-state calculations were carried out for defined boundary conditions in the form of pressure drop. The simulations were applied taking into account the slip phenomenon described by Maxwell’s slip model and TMAC.

Findings

Values of permeability were calculated for different values of TMAC, which vary from 0 to 1. Results in the form of gas mass flow rates were compared with the measured value of permeability for rock sample, which confirmed the high accuracy of the presented model.

Practical implications

Calculations of fluid flow in porous media using CFD can be used to determine rock samples’ permeability. In slip flow regime, Maxwell’s slip model can be applied and the empirical value of TMAC can be properly estimated.

Originality/value

This paper presents the usage of CFD, Maxwell’s equation for partial slip modelling, in fluid flow mechanism for tight rock samples. 3D geometric models were generated using created pre-processor (poROSE software) and applied in the raw form for simulation.
A systematic literature review of emotional labor research from the hospitality and tourism literature
Authors: Lee Lindsey , Madera Juan M.
Published: June 2019

Purpose

The purpose of this paper is to provide an exhaustive review of emotional labor research from the hospitality and tourism literature by outlining the theories, the antecedents and the outcomes of emotional labor, as well as the underlying mechanisms (i.e. mediators and moderators) of emotional labor.

Design/methodology/approach

This study provides a qualitative and critical review of emotional labor research from the hospitality and tourism literature, providing insights into the trends and gaps in the literature.

Findings

The conservation of resources theory and affective event theory are the two most common theories in the reviewed literature. Emotional intelligence and personality are the most commonly investigated antecedents while burnout and job satisfaction are the most investigated outcomes of emotional labor. Stress and burnout are the most examined mediators of emotional labor and subsequent outcomes, such as commitment, turnover intentions and well-being. Moderators include leader-member exchange, job position, gender and climate of authenticity.

Practical implications

Four major gaps for research and practice are identified as follows: the lack of an overarching theoretical framework; inconsistency in how emotional labor is defined and measured; the vast majority of emotional labor studies are cross-sectional studies; and no research examines potential interventions to help service employees engage in effective emotional labor strategies.

Originality/value

This review offers a model providing a comprehensive framework that outlines the various antecedents, outcomes, mediators and moderators of emotional labor and corresponding theories for future research.
Event attendance motives, host city evaluation, and behavioral intentions
Authors: Jiang Yangyang , Chen Ning (Chris)
Published: June 2019

Purpose

This paper aims to examine the event attendance motives and the underlying mechanism through which event attendance motives influence positive word-of-mouth (PWOM) and revisit intentions. It also investigates how event attendance motives differ by gender.

Design/methodology/approach

A self-completed survey administered in English among visitors to the 2016 Olympic Games generated 230 valid responses. Partial least squares-based structural equation modeling was applied to test research hypotheses.

Findings

Event attendance motives of esthetics and escape positively influence host city evaluation. Host city evaluation positively influences PWOM and revisit intentions. Host city evaluation mediates the relationship between event attendance motives (esthetics and escape) and behavioral intentions (PWOM and revisit intentions). Male Olympic tourists show significantly lower means in the motives of social bond and escape when compared with female Olympic tourists.

Originality/value

This study adds to the body of knowledge concerning Olympic tourists, their motives and behavioral intentions. Research findings indicate that event attendance motives influence PWOM and revisit intentions through the mediating effect of host city evaluation. Considering the noticeable paucity of gender analysis weakens the understanding of the Olympic tourist behavior, this study contributes to the literature by examining gender differences in Olympic attendance motives.
Triadic mentoring in early childhood teacher education: the role of relational agency
Authors: Ben-Harush Aya , Orland-Barak Lily
Published: June 2019

Purpose

Current approaches to early childhood teacher education have moved from a view of student–teacher training as interactions involving one novice and one expert, to a process that demands resources and engagement of several professional players while mediating students’ learning in practice. The purpose of this paper is to examine the impact of a triadic mentoring model of a university–school collaboration (“Academia–Classroom”) on student teachers’ (STs) learning in the context of early childhood education in Israel. Eight mentoring triads were formed in six kindergartens. Each mentoring triad was comprised of the ST, a cooperating teacher and the college supervisor. This paper focuses on three representative triads of the eight that were studied.

Design/methodology/approach

The in-depth study adopted qualitative methodology including three complementary data-collection sources: observations of the STs working with children in the kindergarten; observations and recordings of the triadic mentoring conversations following the observations; in-depth interviews with each participant in the mentoring triad. Data were analyzed using an interpretative framework developed for the study, which combined elements from Engestrom’s cultural historical activity theory, Gee’s building tasks and Edward’s relational agency.

Findings

The research identified three major patterns of interaction operating in the mentoring triad that promoted or hindered the learning process of early childhood education students: dissonant, harmonic and argumentative. The way in which relational agency developed in the triads was found to be the most significant aspect of students’ learning process.

Originality/value

The patterns of interaction identified shed light on new aspects of relational agency, thus offering additional interpretative lenses for examining how relational agency operates in ST mentored learning processes. These new identified patterns have practical implications for the design of mentoring frameworks in early childhood teacher education.
Logistics service triad for household waste: consumers as co-producers of sustainability
Authors: Halldórsson Árni , Altuntas Vural Ceren , Wehner Jessica
Published: June 2019

Purpose

The purpose of this paper is to explore the sustainability of waste supply chains regarding the energy efficiency of first-mile waste collection systems and quality of waste. Roles of actors in the waste service triad are considered, particularly focusing on households.

Design/methodology/approach

Primary data are collected from respondents including municipality officers, waste service providers (WSPs) and households through brainstorming sessions, semi-structured interviews, site visits and a focus group. Secondary data are collected from official reports for validation.

Findings

Findings reveal tension between the energy efficiency of waste collection logistics and the quality of waste collected. Households are co-producers of logistic services providing important inputs in the form of sorting and moving waste and raw materials into new cycles of goods circulating in logistics systems. Other actors in the logistics service triad are the municipality as regulator and the WSP acting as a reverse-logistics service provider.

Practical implications

This study provides principles for policymakers and practitioners to evaluate the energy efficiency of waste management options, considering the quality of waste. Also, “logistics services” and “quality of waste” as concepts might provoke new thoughts on how to involve the consumer in resource recovery.

Originality/value

Few studies have focused on the end-consumer’s role in waste supply chains. By considering waste as a resource and the consumer as the supplier of this input, this study provides a new way to think about logistics services for waste collection.
Framework for measurement of supplier satisfaction
Authors: Hudnurkar Manoj , Ambekar Suhas Suresh
Published: June 2019

Purpose

The purpose of this paper is to design, develop, implement and validate a multi-criteria decision model for measuring supplier satisfaction through a case study.

Design/methodology/approach

A three-stage methodology was used to develop a framework to measure supplier satisfaction. The framework involved factors and Key Performance Indicators (KPIs) from literature and exploratory study. Further, using the framework, a multi-dimensional decision model to calculate Supplier Satisfaction Index was developed. The proposed decision framework was implemented as a real-world case study in an Indian manufacturing organization.

Findings

The study makes two major contributions: first, it develops a framework to measure supplier satisfaction using factors and KPIs suitable to the buyer organization; second, the model developed to calculate supplier satisfaction helps in understanding overall satisfaction of suppliers along with the level of satisfaction of each supplier. The model can also be used to suggest improvements to buyer organizations on specific factors and KPIs under each factor.

Research limitations/implications

Supplier satisfaction plays an important role in multinational companies (MNCs), so the sample of practitioners considered in this study is relevant. However, it is likely that the small sample size of only suppliers and companies selected solely from the Indian manufacturing MNCs may have introduced some bias.

Practical implications

A comprehensive framework for enhancing the relationship with suppliers will be instrumental in deciding, managing and improving the level of supplier satisfaction.

Originality/value

This approach provides purchase managers with the flexibility of selecting factors and KPIs at every level of analysis and also a single index to establish supplier’s satisfaction with a buyer company.
A study on prognostic analysis of attachment lugs under off-axis loading
Authors: Kenchappa Bharath , Chikmath Lokamanya , Dattaguru Bhagavatula
Published: June 2019

Purpose

Lug joints with fasteners play a crucial role in connecting many major components of the aircraft. Most of the failures in the past were credited to the damages initiating and progressing from these types of joints. Ensuring the structural integrity of these fastener joints is a major issue in many engineering structures, especially in aerospace components, which would otherwise lead to fatal failure. The purpose of this paper is to adopting the prognostic approach for analysing these lug joints with fasteners subjected to off-axis loading by estimating the crack initiation and crack growth life of these joints. This data will be useful to estimate the remaining life of these joints at any given stage of operations, which is mandatory in structural health monitoring (SHM).

Design/methodology/approach

Straight and tapered lug joints are modelled using the finite element method in MSC PATRAN and analysed in MSC NASTRAN. These lug joints are analysed with a push fit fastener. The contact/separation regions at the pin–lug interface are carefully monitored throughout the analysis for various loading conditions. Critical locations in these lug joints are identified through stress analysis. Fatigue crack initiation and fatigue crack growth analysed is carried out at these locations for different load ratios. A computational method is proposed to estimate the cycles to reach crack initiation and cycles at which the crack in the lug joint become critical by integrating several known techniques.

Findings

Analysis carried out in this paper describes the importance of tapered lug joints, particularly when subjected to non-conventional way of loading, i.e. off-axis loading. There is a partial loss of contact between pin and lug upon pin loading, and this does not change further with monotonically increasing pin load. But during load reversals, there is a change in contact/separation regions which is effectively handled by inequality constraints in the boundary conditions. Crack growth in these lug joints pertains to mixed-mode cracking and is computed through the MVCCI technique.

Originality/value

Most of the earlier works were carried out on in-plane pin loading along the axis of symmetry of the lug. The current work considers the off-axis pin loading by loading the lug joints with transverse and oblique pin load. The significance of taper angle under such loading condition is brought in this paper. The results obtained in this paper through prognostic approach are of direct relevance to the SHM and damage tolerance design approach where the safety of the structural components is of foremost priority.
Financial and social efficiency in the Yemen microfinance institutions
Authors: Al-Awlaqi Mohammed Ali , Aamer Ammar Mohamed
Published: June 2019

Purpose

The purpose of this paper is to discover the most important productivity determinants of Yemeni microfinance institutions. In addition, this study tests the most appropriate tool to measure productivity in such unique industry.

Design/methodology/approach

The authors applied data envelopment analysis (DEA) with the variable return to scale after testing the technology return to scale assumption. Then, they used DEA with bootstrapping technique to overcome the borne biasness in the conventional DEA analysis. Finally, the authors presented the Hicks–Moorsteen (total factor productivity [TFP]) as the most suitable tool for the technology presented in this study.

Findings

In this paper, the authors found a prolonged deterioration in the productivity scores of microfinance institutions in Yemen. This study highlights the importance of operating in rural areas to improve micro finance institutions’ (MFIs’) productivity. In contrast, they found no significant differences in productivity, neither between microfinance banks and non-governmental organizations nor between Islamic and non-Islamic MFIs.

Research limitations/implications

This study extends previous research in the area of productivity and its determinants. It also adds to the body of productivity knowledge and methodology within the context of the microfinance industry in Yemen.

Originality/value

The study discovered new productivity determinants and re-assessed the importance of some already known ones. These determinants have been studied for the first time in Yemen’s microfinance industry and have contributed to answer the question of what is the most suitable productivity method that should be used. This study proved that the Hicks–Moorsteen TFP and the variable return to scale assumption are the only suitable methods to study productivity in the microfinance industry.
Factor influencing flexibility in new product development: empirical evidence from Indian manufacturing firms
Authors: Mishra Ruchi , Mishra Onkar Nath
Published: June 2019

Purpose

A significant amount of work has been done on new product development (NPD); however, studies on the flexibility aspect in NPD are scant. This study aims to investigate the relationship between NPD flexibility and five infrastructural factors, namely, marketing and manufacturing integration practices (MMIPs), advanced human resource practices (AHRPs), supplier integration practices (SIPs), operational improvement practices (OIPs) and advanced manufacturing technologies (AMTs).

Design/methodology/approach

The study applies a questionnaire-based survey approach to examine the proposed relationships between different variables and NPD flexibility. Using a 39-item questionnaire, 262 valid and usable responses were collected from Indian manufacturing firms. Data were analysed using principal component analysis and confirmatory factor analysis. Further, structural equation modelling was applied to examine the contribution of different infrastructural factors to NPD flexibility.

Findings

In light of the empirical evidence produced in this study, the study suggests that MMIPs, AHRPs, SIPs, OIPs and AMTs have a direct, positive and significant influence on NPD flexibility. Among all the predictors, SIPs are the strongest predictor of NPD flexibility, followed by OIPs and AMTs.

Research limitations/implications

The findings extend prior studies of NPD by broadening the theory related to NPD flexibility. Practitioners should take a macro approach and focus on several practices to enhance flexibility in NPD.

Originality/value

Unlike earlier studies that provide limited empirical evidence on NPD flexibility and deal with the concept in isolation, this empirical study applies a systematic approach to understand factors influencing NPD flexibility.
Predicting manufacturing employee turnover intentions
Authors: Skelton Angie R. , Nattress Deborah , Dwyer Rocky J.
Published: June 2019

Purpose

Employee turnover expenses can cost businesses more than 100 per cent of a single employee’s annual wages and negatively affection an organization’s production and profits. High employee turnover also could affect community tax collections, social programs and physical and mental health issues. Therefore, understanding contributors to higher employee turnover remains essential for organizational managers from both a corporate and societal standpoint. This paper aims to provide an analysis of how job satisfaction and job embeddedness could predict employee turnover intent.

Design/methodology/approach

A randomly selected survey which consisted of Andrews and Withey’s (1976) job satisfaction questionnaire, a global job embeddedness scale (Crossley et al., 2007) and a three-item turnover intent questionnaire derived from a survey created by Mobley et al. (1978) using a Likert-type measurement to survey randomly selected individuals used within manufacturing plants located in the Southeastern USA.

Findings

The results of the multiple regression analysis showed a significant relationship between job satisfaction, job embeddedness and turnover intent; and that satisfied and committed employees are less likely to plan to leave their employment.

Originality/value

Limited current information is available on how job satisfaction and job embeddedness predict turnover intentions in US Southeast manufacturing. This study includes information that shows the importance of job satisfaction and job embeddedness on retaining employees in this region and industry. Given the importance of employee retention on corporate productivity, morale and profits along with the ability to improve the organization’s positive contribution to society, it is important for managers to understand these factors and their effect on employee turnover intent.
The effects of advertising appeals on consumers’ behavioural intention towards global brands
Authors: Raza Syed Hassan , Abu Bakar Hassan , Mohamad Bahtiar
Published: June 2019

Purpose

This study aims to examine the effects of the advertising appeals (AP) on consumers’ behavioural intention, specifically to use global brands. In addition, the study investigates how attitude operates as a process variable that mediates the relationship between AP and behavioural intention (BI). This paper also explores the congruity of individuals’ norms in advertising appeal–intention relationship. Centred on the theory of planned behaviour, this study proposes a model that encompasses norm congruence, in which the degree of individuals’ uncertainty avoidance (UA) moderates the relationship between advertising appeal (AP) and behavioural intention (BI), and attitude towards advertising appeal (AT) serve as key causal mechanism that mediates advertising appeal–behaviour relationship.

Design/methodology/approach

The proposed model was tested using a 2 × 2 experimental design with a sample size of 372.

Findings

Results showed that the relationship between AP and BI based on global brands is significantly mediated by attitude towards AP and moderated by uncertainty avoidance. These findings have yielded partial validation of the proposed model and have provided empirical support for the roles of uncertainty avoidance and attitude towards AP.

Practical implications

The authors propose that marketers should reduce the level of consumers’ uncertainty. Uncertainty avoidance effects can be achieved through the dissemination of norm-congruent advertisement appeals and by placing more weight on social compatibility attributes which may gratify consumers’ interest, sebsequently enhance the intention of Muslim consumers to use global brands.

Originality/value

A moderator is a variable that affects the strength of the relation between the predictor and criterion variable. This paper also explores the congruity of individuals’ norms in advertising appeal–intention relationship. Previous studies did not capture any effects of culturally congruent advertising appeals by considering the level of uncertainty avoidance influence on individuals’ intention to use global brands in a Muslim country context. In response to the recent calls for research to re-examine the antecedents of the theory of planned behaviour, this study re-evaluates the roles of attitude towards AP and the interaction of cultural norms.
Green purchasing capabilities, practices and institutional pressure
Authors: Foo Meow Yee , Kanapathy Kanagi , Zailani Suhaiza , Shaharudin Mohd Rizaimy
Published: June 2019

Purpose

The purpose of this paper is to ascertain the green-purchasing capabilities required to ensure the successful implementation of green-purchasing practices under the forces of institutional pressure. Specifically, this paper explores the green-purchasing capabilities of buyer firms under the influence of institutional pressures in supplier selection, development, collaboration and evaluation in support of environmental purchasing.

Design/methodology/approach

Questionnaire survey method was used to gather data from 163 ISO 14001-certified manufacturing firms in Malaysia. Partial least squares was used for hypotheses testing.

Findings

Green-purchasing capabilities, such as manufacturing, financial, intraorganisational and integration capabilities, have a significant positive effects on green-purchasing practices. However, innovation capabilities have no significant effect on green-purchasing practices. Regulation, customer and competitor pressure positively moderate the relationships between green manufacturing capabilities and practices.

Practical implications

The paper highlights the importance of green-purchasing capabilities in enhancing the green-purchasing practices of firms. The findings that pertain to moderating effect could be used to assist policy makers, particularly in setting appropriate policies and strategies to improve green purchasing.

Originality/value

Although more studies on green purchasing have been conducted in recent years, issues, such as the effect of green-purchasing capabilities on green-purchasing practices, are still unspecified. Besides, this study considers institutional pressure as the moderator when a model is constructed to exemplify the relationship between green-purchasing capabilities and practices.
Creative nonfiction and narrative inquiry
Authors: Levine-Rasky Cynthia
Published: June 2019

Purpose

The purpose of this paper is to describe, situate and justify the use of creative nonfiction as an overlooked but legitimate source of text for use in social inquiry, specifically within the ambit of narrative inquiry. What potential lies in using creative writing, creative nonfiction specifically, as a source of text in social research? How may it be subjected to modes of analysis such that it deepens understandings of substantive issues? Links are explored between creative nonfiction and the social context of such accounts in an attempt to trace how writers embed general social processes in their narrative.

Design/methodology/approach

Three exemplars from literary magazines are described in which whiteness is the substantive theme. The first author is a woman who writes about her relationship with her landscaper, the second story is written by a man who is overwhelmed by guilt after uttering a racial slur, and the third text is by a man who describes his attempts to help a homeless couple. The authors’ interpersonal experiences with people unlike themselves tell something significant about the relationship between selfhood and power relations.

Findings

No singular pattern emerges when analyzing these three narratives through the critical lens of whiteness. This is because whiteness is not a subject position or static identity but a practice, something that it is done in relation to others. It is a collective capacity whose value is realized only in dynamic relationship with others. As a rich source of narratives, creative nonfiction may generate insights about whiteness and middle classness and how their intersections give rise to complex and contradictory sets of social relations.

Originality/value

There is very little precedence for using creative nonfiction as text for analysis in any discipline in the social sciences despite its accessibility, its richness and its absence of risk. Inviting the sociological imagination in its project to link the personal to the political, it opens possibilities for the analysis of both in relationship to each other. As a common form of narrating everyday understandings, creative nonfiction offers something unique and under-valued to the social researcher. For these reasons, the paper is highly original.
The case for a Chinese methodology in educational research
Authors: Liu Wei
Published: June 2019

Purpose

The purpose of this paper is to recover the identity of Chinese intellectual discourse, arguing for the necessity of a Chinese methodology in educational research to be constructed on the basis of the Chinese philosophical traditions and the Chinese social norms for the aim of solving Chinese educational issues within the Chinese cultural context.

Design/methodology/approach

The paper is a theoretical paper, arguing for the ontological, epistemological and methodological basis for a Chinese methodology in educational research.

Findings

The major ontological issue of Chinese social and educational research, also the ultimate goal of the Chinese governance, is social harmony through harmonious personal relationships. The key to social harmony has been seen in the Chinese philosophical tradition as residing in people’s personal morality and obligation, which constitutes the epistemology of Chinese research. And the golden mean of moderation by synthesizing and balancing the dualist extremes of views and actions should be adopted as the methodological paradigm to researching social and educational issues in China.

Practical implications

The elaboration of these three entities holds promises in the construction of the Chinese methodological system on Chinese social terms and merits.

Originality/value

The author has long sensed that the extensive methodological borrowing from the West by Chinese scholars in educational research might be problematic, given the vast structural differences in the two social worlds that the author and other scholars have observed. A paper in English to argue for the necessity of constructing a uniquely Chinese methodology for educational research in China is an absolute necessity.
From apparent competition to facilitation: Impacts of consumer niche construction on the coexistence and stability of consumer‐resource communities
Authors: Picot Aurore , Monnin Thibaud , Loeuille Nicolas
Published: June 2019

In addition to their direct trophic effects, some consumers have a positive indirect effect on their resource, due to niche construction. A predator can facilitate its prey resource acquisition, through prey transport, or through modifications of nutrient cycling. Alternatively, a predator may defend its prey against other predators, or actively manage it, as in agriculture, which is found in numerous taxa such as humans, ants, beetles, fishes and microbes.

Here, we investigate the ecological consequences of considering such positive effects in a simple two‐resource–one‐consumer module, in which the consumer has a positive effect on one of the resources.

We consider several scenarios, in which the positive effect on the resource is either not costly, that is resulting from a by‐product of the consumer phenotype such as nutrient cycling, or costly. The cost either decreases the exploitation of the cultivated resource or the opportunity to forage the alternative resource. We investigate how the intensity of niche construction impacts species coexistence, the distribution of biomass among the three species and the stability of the community.

We show that by modifying the trophic interactions in the module, niche construction alters the apparent competition between the resources, thereby impacting their coexistence.

When niche construction has little or no cost to the consumer, it leads to higher consumer and cultivated resource densities, while decreasing the alternative resource density. Alternatively, when niche construction has higher costs, the alternative resource can increase in density, niche construction thereby leading to the emergence of facilitative interactions among resource species.

Stomatal sensitivity to CO2 diverges between angiosperm and gymnosperm tree species
Authors: Klein Tamir , Ramon Uria
Published: June 2019

The response of tree leaf gas exchange to elevated CO2 concentrations has been investigated in numerous experiments along the past 30 years. Stomatal regulation is a major plant control over leaf gas exchange, and the response to the increasing CO2 will shape the biological activity of forests in the future.

Here, we collected 144 records from 57 species on stomatal conductance in CO2 manipulation experiments on trees (340–980 ppm CO2). CO2‐induced stomatal downregulation was calculated as the slope of the linear regression between stomatal conductance and [CO2].

Among tree species, the slope (a) of change in stomatal conductance per 100 ppm CO2 increase ranged between 0 and −151, indicating stomatal downregulation, and only four species showed upregulation. There was a significant divergence between evergreen gymnosperms (a = −3.6 ± 1.0), deciduous angiosperms (a = −16.3 ± 3.1) and evergreen angiosperms (a = −32.8 ± 7.1). Gymnosperms were less sensitive to CO2 changes than deciduous angiosperms even when considering only field experiments. The significant role of tree functional group in predicting CO2‐induced stomatal downregulation was detected in multiple mixed‐effect models, with p values ranging between 0.0002 and 0.0295.

The significantly higher stomatal sensitivity to CO2 of angiosperms versus gymnosperms might be related to the overall higher stomatal conductance of angiosperms; their thinner leaves, in turn losing water faster; and the decreasing atmospheric [CO2] at the time of their taxa diversification. We conclude that species differences must be taken into account in forecasting future forest fluxes.
