AbstractA highly aggressive subset of pancreatic ductal adenocarcinomas undergo trans-differentiation into the squamous lineage during disease progression. While the tumorigenic consequences of this aberrant cell fate transition are poorly understood, recent studies have identified a role for the master regulator TP63 in this process. Here, we investigated whether squamous trans-differentiation of pancreatic cancer cells can influence the phenotype of non-neoplastic cells in the tumor microenvironment. Conditioned media experiments revealed that squamous-subtype pancreatic cancer cells secrete factors that convert quiescent pancreatic stellate cells into a specialized subtype of cancer-associated fibroblasts (CAFs) that express inflammatory genes at high levels. We use gain- and loss-of-function approachesin vivoto show that squamous-subtype pancreatic tumor models become enriched with inflammatory CAFs and neutrophils in a TP63-dependent manner. These non cell-autonomous effects occur, at least in part, through TP63-mediated activation of enhancers at pro-inflammatory cytokine loci, which includesIL1Aas a key target. Taken together, our findings reveal enhanced tissue inflammation as a consequence of squamous trans-differentiation in pancreatic cancer, thus highlighting an instructive role of tumor cell lineage in reprogramming the stromal microenvironment.
Empirical analysis of doctoral candidates’ innovative personality model based on grey target decision making
Authors: Sun Caiyun 
Published: November 2019

Purpose
The purpose of this paper is to analyze the reliability and validity of doctoral candidates’ innovative personality model.

Design/methodology/approach
Based on doctoral candidates’ innovative personality model, this study took the best correlation and the worst correlation into account to predict and demonstrate their innovative ability tendencies. Matlab R2016a, a program of software programming, was used to calculate the contribution degree of each personality factor of doctoral candidates to their innovative ability tendencies.

Findings
The reliability and validity of doctoral candidates’ innovative personality model based on grey target theory have been verified, and the prediction for doctoral candidates’ innovative ability tendencies can be realized on the basis of this model.

Practical implications
Scientific and reasonable doctoral candidates’ innovative personality model can play a good guiding role, and its research results have certain practical significance for selecting innovative doctoral candidates, ensuring the training quality of doctoral candidates and cultivating the innovative ability of doctoral candidates. It can be promoted and applied on the basis of its trial operation in Jiangsu.

Originality/value
With regard to the relative degree of the influence of doctoral candidates’ individual personality factors, previous researchers seldom carried out the quantitative research. In this paper, the author sought a quantitative method to describe the degree of such influence and constructed the doctoral candidates’ innovative personality model based on grey target decision making. This study took the positive and negative off-target distance into account and demonstrated the rationality and validity of doctoral candidates’ innovative personality model.
The hidden historiography of migration and Australian schooling
Authors: Proctor Helen 
Published: November 2019

PurposeDespite Australia’s history as an exemplary migrant nation, there are gaps in the literature and a lack of explicit conceptualisation of either “migrants” or “migration” in the Australian historiography of schooling. The purpose of this paper is to seek out traces of migration history that nevertheless exist in the historiography, despite the apparent silences.Design/methodology/approachTwo foundational yet semi-forgotten twentieth-century historical monographs are re-interpreted to support a rethinking of the relationship between migration and settler colonialism in the history and historiography of Australian schooling.FindingsThese texts, from their different school system (state/Catholic) orientations, are, it is argued, replete with accounts of migration despite their apparent gaps, if read closely. Within them, nineteenth-century British migrants are represented as essentially entitled constituents of the protonation. This is a very different framing from twentieth century histories of migrants as minority or “other”.Originality/valueInstead of an academic reading practice that dismisses and simply supersedes old work, this paper proposes that fresh engagements with texts from the past can yield new insights into the connections between migration, schooling and colonialism. It argues that the historiography of Australian schooling should not simply be expanded to include or encompass the stories of “migrants” within a “minority studies” framework, although there is plenty of useful work yet to be accomplished in that area, but should be re-examined as having been about migration all along.
The impact of training and development practices on innovation and financial performance
Authors: Manresa Alba , Bikfalvi Andrea , Simon Alexandra 
Published: November 2019

PurposeOver recent years, firms have been implementing novel human resource practices. The purpose of this paper is to analyse four specific training practices to determine if and up to what extent the adoption of such practices affects innovation and financial performance.Design/methodology/approachA Spanish sub-sample of the European Manufacturing Survey is used to contain the responses of 162 manufacturing firms.FindingsThe positive relation between T&D practices and innovative performance was partially accepted, as new-to-the-firm products and new services had a significant relation with these practices. Conversely, the hypothesis stating that there is a positive relation between a new-to-the-market product and the aforementioned T&D practices was rejected. Furthermore, the positive relation between these and financial performance was partially accepted.Research limitations/implicationsThis research presents the following limitation: the small number of responses restricts the general reliability of the findings. The inclusion of other countries’ data using the same questionnaire would further enrich the analysis.Practical implicationsFirst, general training and development is not enough; thus, the present study evidences the positive results of specific training practices such as training and development for creativity and innovation (TD4CI) on firm performances. Second, it also reveals a relation between training practices and innovation by differentiating among the three dimensions of innovation (new product to the firm, new product to the market and new services). Moreover, the present research highlights the benefits of implementing these types of practices, not only for innovation performance but also for financial performance. This paper also suggests that not all the training practices have the same impact on firm performance. Consequently, the company should be clear about their main aim to obtain the highest performance. The third contribution is based on the Spanish context wherein training is not considered as an important organisational function. Thus, this study provides positive results showing that TD4CI might enhance firm performance. Last, the degree of detail of the different training practices analysed, the recent nature of the data related to their implementation and the link between implementation and organisation performance are also part of the contribution of the present analyses.Originality/valueThis research offers recent and relevant data about implementing novel T&D practices and their relation with firm performance.
Tribological performance of a surface textured meso scale air bearing
Authors: Hingawe Nilesh D. , Bhore Skylab P. 
Published: November 2019

Purpose
The purpose of this study is to improve the tribological performance of meso scale air journal bearing by adopting texture on the bearing surface.

Design/methodology/approach
The present study is based on numerical analysis. The detailed numerical investigation is carried out using a fluid flow based thin-film model in COMSOL 5.2 software.

Findings
The influence of texture design parameters: geometry (shape, orientation and slender ratio), and position on the tribological performance of meso scale air journal bearing is investigated. It is found that texture shape has a strong influence on the tribological characteristics such as load capacity and friction coefficient of the bearing. Slender texture improves the load capacity, but it has a negligible effect on the reduction of friction coefficient. In contrast, texture orientation is found to be insignificant for both increasing load capacity and decreasing friction coefficient. Furthermore, the maximum improvement in load capacity is obtained for partially textured bearing, but the minimum friction coefficient is achieved for full texturing.

Originality/value
The present study investigates the influence of texture design parameters viz geometry (shape, orientation and slender ratio), and position on the tribological performance of meso scale air journal bearing.
International buyers’ repurchase intentions in a Chinese cross-border e-commerce platform
Authors: Mou Jian , Cohen Jason , Dou Yongxiang , Zhang Bo 
Published: November 2019

Purpose
The purpose of this paper is to develop and test a model of the uncertainties and benefits influencing the repurchase intentions of buyers in cross-border e-commerce (CBEC).

Design/methodology/approach
The authors draw on the valence framework to hypothesize effects of positive valences (utilitarian benefits) along with negative valences (pre- and post-contractual uncertainties) on buyers’ repeat purchase intentions. Data were collected using an online survey from 378 international B2C buyers on a CBEC platform in China.

Findings
Results explain 51.4 percent of the variance and reveal that overall value, as determined by monetary saving, convenience and product offerings as positive valences, exerts the strongest effect on repeat purchase intention. However, negative valences remain significant, and are particularly salient for female shoppers.

Research limitations/implications
The authors extend the valence theory into the study of repeat purchase behavior and contribute to much needed literature on why consumers return to repurchase from a CBEC platform.

Practical implications
Repeat purchase and loyalty of online consumers is essential for success of e-commerce providers. The results help online providers competing in international markets understand how buyers form repurchase intentions based on their evaluations of both value and uncertainty.

Originality/value
Buyer behavior in CBEC has received relatively less attention than domestic e-commerce. This paper is among the first to examine how both positive and negative valences combine to effect repurchase intention of international buyers in CBEC.
Sustainable practices in SMEs: reducing the ecological footprint
Authors: Franco Mário , Rodrigues Margarida 
Published: November 2019

PurposeThe purpose of this study to focus on sustainable entrepreneurship practices in small and medium-sized enterprises (SMEs), thus aiming to understand the reasons owners-managers implement them as well as the benefits they provide after considering the three domains of sustainable development: environmental, social and economic.Design/methodology/approachA qualitative approach was adopted using two Portuguese cases (SME). Data were obtained from interviews and documentary analysis.FindingsFrom content analysis of the interviews held, the results obtained show that both SMEs studied are concerned about sustainable practices and development. They have competences directing them towards a sustainable entrepreneurship.Practical implicationsThe study contributes to understanding the benefits of adopting sustainable entrepreneurial practices in the SME context and helping these firms’ managers reformulate more appropriate and effective strategies and actions to ground these firms in a process of continuous improvement, especially in reducing their environmental footprint.Originality/valueAlthough SMEs are numerous and central in the dynamics of the world economy, sustainable entrepreneurial practices have not been studied as a vehicle to reduce the ecological footprint. This holds particularly true for the realm of SMEs.
Exchange rate exposure and firm productivity in India
Authors: Mohapatra Sonali Madhusmita 
Published: November 2019

Purpose
The purpose of this paper is to investigate the linkage between exchange rate exposure and firms’ productivity in India. This study also tries to compare the effects of exchange rate exposure on the productivity of the pre- and post-financial crisis periods and also between export- and import-oriented firms.

Design/methodology/approach
By using the annual data of 232 manufacturing and service sector firms for the period of 2000-2013, this paper examines the exchange rate exposure and firms’ performance in India. In the first stage, the two-factor regression model, Adler and Dumas, is used, and in the second stage, the Levinsohn and Petrin (2003) approach is used for estimating the total factor productivity of significant firms. Finally, for examining the relationship between exchange rate exposure and productivity, the instrumental variable panel data regression model is used.

Findings
This study observes that a negative relation exists between the appreciation of exchange rate exposure and firms’ productivity. The study also reveals that the export-oriented firms make loss during exchange rate appreciation which decreases the productivity. The financial crisis has the negative impact on productivity, as well.

Originality/value
Although there are an ample number of studies which examined the effects of the exchange rate on firm’s export, growth, investment, however impact of exchange rate exposure on productivity at firm level is scanty. This study tries not only to compare the effects of exchange rate exposure on the productivity of the pre- and post-financial crisis periods but also between the export- and import-oriented firms which is another innovation of this study.
The effect of changing fiscal year-ends on audit fees and audit quality
Authors: Pacheco Paredes Angel Arturo , Wheatley Clark 
Published: November 2019

Purpose
This study aims to extend recent research analyzing the effect of auditor busyness on audit quality. Specifically, this study explores the effect on audit quality of a change of fiscal year-end to or from an audit firm’s busy period.

Design/methodology/approach
Empirical archival.

Findings
When firms change their fiscal year-end to a period when the auditor is less busy, client firms are rewarded with lower audit fees and auditors are rewarded with a reduction in required effort. This study finds no difference in the level of audit quality after a change in fiscal year-end.

Practical implications
There are significant implications for audit firms as they may gain cost advantages by successfully promoting off-season fiscal year-ends, and reduce the negative effect on employees associated with “busy season” stress. Similarly, client firms may find that audit costs are reduced when they adopt a less “busy” fiscal year-end.

Social implications
These results have policy implications for regulators because regulators often dictate the fiscal year-end for certain industries or traded securities. Such dictates may thus introduce inefficiencies into the market for audit services.

Originality/value
These results should guide regulators in their decisions to dictate fiscal year-ends and firms in their choice of reporting periods.
Engaging young people through photovoice in coastal resorts
Authors: Tickle Sarah 
Published: November 2019

Purpose
The purpose of this paper is to examine and reflect upon the value of using a camera with young people in the research process. In particular, the paper discusses the opportunities that a camera can bring when researching young people’s lives, subsequently encouraging the use of photovoice with young people in ethnographic research.

Design/methodology/approach
The paper examines how photovoice can be a beneficial method of data collection when researching young people’s lives. By adopting a qualitative participatory approach, and employing photovoice as one of the main methods, rich and meaningful data were gathered that traditional qualitative methods alone would not have captured.

Findings
Photovoice was used alongside traditional methods to explore how young people experienced and perceived policing, safety and security in a coastal resort. Using a camera, captured rich images which alongside the narratives given by the young people, provided profound and detailed accounts.

Originality/value
Using innovative participatory qualitative research methods with young people and adapting to the research setting allowed for deep and meaningful explorations of young people’s lives to be gathered. Carefully considering the use of appropriate methods of data collection and selecting methods that are “fun” and “interesting” empowered young people and provided the researcher with an insight into their social worlds.
Military expenditure and economic growth: the case of India
Authors: Abdel-Khalek Gouda , Mazloum Mohammed Gamal , El Zeiny Mohammed Ramadan Mohammed 
Published: November 2019

Purpose
The relationship between military expenditure and economic growth is complex. The purpose of this paper is to examine this relationship in India.

Design/methodology/approach
The design of this study is descriptive in the theoretical part, and quantitative in the applied one. The study uses time series approach, and Hendry General-to-Specific (GTS) modeling methodology, to examine and analyze the relationship between military expenditure and economic growth in India, during the period 1980-2016.

Findings
The study shows the following: Absence of causal relationship between military expenditure and economic growth in India, during indicated period. The continuous regional tensions facing India represent the main factor for adopting Indian military strategy and emphasizing military capabilities. India has been able to build and develop links between civilian and military sectors. The Indian military scientific and manufacturing policies have achieved self-sufficiency in some of its military needs, a strong military industrial base and high levels of military exports. India participated with developed countries in military strategic industries. Such participation contributed to the integration of civilian and military sectors. India gave rights to private sector and foreign direct investment (FDI) for manufacturing in military industries, giving full marketing rights to the Indian government. These new policies considered a great move toward deep changes for Indian military manufacturing policy.

Social implications
The findings shed light on the importance of stimulating links between civilian and military sectors, particularly in the industrial sectors and scientific activities.

Originality/value
This study has a contribution to literature of military expenditures' economic effects. Theoretically, this study tries to fill the research gap regarding the impact of military expenditure in Indian case. Furthermore, to the best of the authors' knowledge, this is the first study that examines the relationship between military expenditure and economic growth in India using Hendry general-to-specific (GTS) modeling methodology and time series approach.
Activation energy for Cu-Sn intermetallic in CNT-reinforced Sn-1.0Ag-0.5Cu solder
Authors: Mayappan Ramani , Salleh Amirah , Tokiran Nurul Atiqah , Awang N.A. 
Published: November 2019

Purpose
The purpose of this study is to investigate the addition of 0.05 Wt.% carbon nanotube (CNT) into the Sn-1.0Ag-0.5Cu (SAC) solder on the intermetallic (IMC) growth. Lead-based solders play an important role in a variety of applications in electronic industries. Due to the toxicity of the lead in the solder, lead-free solders were proposed to replace the lead-based solders. Sn-Ag-Cu solder family is one of the lead-free solders, which are proposed and considered as a potential replacement. Unfortunately, the Sn-Ag-Cu solder faces some reliability problems because of the formation of the thick intermetallic compounds. So the retardation of intermetallic growth is prime important.

Design/methodology/approach
The solder joint was aged under liquid state aging with soldering time from 1 to 60 min.

Findings
Two types of intermetallics, which are Cu6Sn5 and Cu3Sn were observed under a scanning electron microscope. The morphology of Cu6Sn5 intermetallic transformed from scallop to planar type as the soldering time increases. The addition of carbon nanotube into the SAC solder has retarded the Cu6Sn5 intermetallic growth rate by increasing its activation energy from 97.86 to 101.45 kJ/mol. Furthermore, the activation energy for the Cu3Sn growth has increased from 102.10 to 104.23 kJ/mol.

Originality/value
The increase in the activation energy indicates that the growth of the intermetallics was slower. This implies that the addition of carbon nanotube increases the reliability of the solder joint and are suitable for microelectronics applications.
Dispersal limitation relative to environmental filtering governs the vertical small‐scale assembly of soil microbiomes during restoration
Authors: Chen Weimin , Jiao Shuo , Li Qiaoping , Du Nini 
Published: November 2019

Abstract

Uncovering the plant‐soil feedback mechanisms underlying the assembly of belowground microbial communities is essential for terrestrial biodiversity conservation. However, little is known about the small‐scale spatial assembly processes of distinct soil microorganisms, especially during natural restoration of ex‐arable ecosystems.

We examined the spatial structure of soil microbiomes in arable land and reforested soils to elucidate the underlying assembly processes at a small spatial scale. The analysis was based on a MiSeq sequencing database, detecting the diversity of archaeal, bacterial and fungal communities, simultaneously, from 300 soil samples along vertical and horizontal profiles during 30‐year reforestation.

Compared with environmental filtering, dispersal limitation made crucial contributions to microbial community assembly. Archaeal and bacterial communities with a wider niche breadth were governed more by dispersal limitation than were fungal communities.

The effect of dispersal limitation on archaeal and bacterial communities increased first and then decreased over time, while the effect on fungi temporally increased.

Synthesis and applications. Our results highlight the variation of assembly processes governing distinct soil microbiomes during reforestation, with dispersal limitation playing a prominent role. This finding suggests that the increase in soil microbial diversity during natural restoration is mainly due to the stochastic influx and dispersal of microorganisms. This greater understanding of microbial community assembly can contribute to more targeted and efficient environmental management practices for the restoration of terrestrial ecosystems, for example, by promoting the restoration practices and shortening the restoration period. These practices may thus be incorporated into policies developed for effective biodiversity conservation, especially the restoration and maintenance of subsurface soil microbial diversity and associated functions.
