Corpus linguistics, newspaper archives and historical research methods
Authors: Tumbe Chinmay 
Published: May 2019

Purpose
The purpose of this paper is to demonstrate the utility of corpus linguistics and digitised newspaper archives in management and organisational history.

Design/methodology/approach
The paper draws its inferences from Google NGram Viewer and five digitised historical newspaper databases – The Times of India, The Financial Times, The Economist, The New York Times and The Wall Street Journal – that contain prints from the nineteenth century.

Findings
The paper argues that corpus linguistics or the quantitative and qualitative analysis of large-scale real-world machine-readable text can be an important method of historical research in management studies, especially for discourse analysis. It shows how this method can be fruitfully used for research in management and organisational history, using term count and cluster analysis. In particular, historical databases of digitised newspapers serve as important corpora to understand the evolution of specific words and concepts. Corpus linguistics using newspaper archives can potentially serve as a method for periodisation and triangulation in corporate, analytically structured and serial histories and also foster cross-country comparisons in the evolution of management concepts.

Research limitations/implications
The paper also shows the limitation of the research method and potential robustness checks while using the method.

Practical implications
Findings of this paper can stimulate new ways of conducting research in management history.

Originality/value
The paper for the first time introduces corpus linguistics as a research method in management history.
Research Watch: can adversity make you stronger?
Authors: Holttum Sue 
Published: May 2019

Purpose
The purpose of this paper is to examine what helps people come through difficult events and circumstances.

Design/methodology/approach
A search was carried out for recent papers on adversity and thriving.

Findings
One paper reviewed 27 studies of coping and wellbeing after adversities. Maybe some kinds of adversity can help us get stronger, but people’s social contexts were not considered and the studies measured different things that may not be as easily compared as first appears. A second paper examined wellbeing at work, and reported that a certain type of supervisor is important for preventing burnout. The final paper reported on 55 people who survived depression. Many (though not all) participants felt their life was better than before. Surviving was assisted by practical and social support rather than pills.

Originality/value
The review of research on adversity highlights that patterns of data may look similar but may not tell us as much as we hoped. The study of workplace thriving highlighted how supervisors might support people to do their best work while preventing burnout. The study on surviving depression suggested that social resources were key to a good outcome and a better life. Social inclusion is likely to be important.
Cultural intelligence effects on expatriates’ adjustment and turnover intentions in Mainland China
Authors: Akhal Khalid , Liu Shimin 
Published: May 2019

PurposeExpatriates’ cross-cultural adjustment is one of the crucial factors for multi-national corporations’ (MNCs’) global success, which if neglected can lead to poor performance and increased turnover rates. On the other hand, cultural intelligence (CQ) is an important perspective for understanding international business success. Utilizing a relatively large sample of foreign professionals (n= 402) working in Mainland China, this study aims to test the effects of cultural intelligence on expatriates’ cross-cultural adjustment and their turnover intentions.Design/methodology/approachData were collected via a cross-sectional survey, and the hierarchical multiple regression technique was used to test the hypotheses. The facets of cross-cultural adjustment were treated as potential predictors of turnover intentions and mediators in the relationship between CQ and turnover intentions.FindingsWith the exception of CQ-behavioral, the other three dimensions of CQ had varying positive effects on the three facets of expatriates’ cross-cultural adjustment. When the variable of turnover intentions was regressed on the four dimensions of CQ, the motivational dimension was the only predictor. Also, general and work adjustment facets had strong effects on turnover intentions, thus when they entered in the third step after CQ-motivational, they provided full mediation.Practical implicationsGiven the strong and positive effects of all CQ dimensions on all facets of cross-cultural adjustment, MNCs should assess and select individuals with high CQ levels for international assignments. Based on the correlations of the control variables, age and level of education, MNCs should keep an eye on those who are young and those with higher levels of education as they are more likely to leave their international assignments prematurely. Expatriates themselves should set long-term personal plans for acquiring the needed cultural knowledge.Originality/valueThis research extends the relationship between CQ and cross-cultural adjustment to expatriates’ turnover intentions, a very costly problem for MNCs, yet barely researched in the context of CQ. This study also extends the geographical validity of CQ to Mainland China, a very lucrative market for global MNCs, yet a challenge for Western expatriates in particular.
Stock market stress from the central counterparty’s perspective
Authors: Dömötör Barbara , Váradi Kata 
Published: May 2019

Purpose
The purpose of this paper is to investigate the possibility of monitoring stress on stock markets from the perspective of a central counterparty (CCP). Due to their balanced positions, CCPs are exposed to extreme price movements in both directions; thus, the major risk for them derives from extreme returns and market illiquidity. The authors examined the connection of the stress alarms of return- and liquidity-based measures to find an objective basis for stress measurement.

Design/methodology/approach
The authors defined two types of stress measures: indicators based on extreme returns and liquidity. It is suggested that the stress indicators should be based on the existing risk management methodology that examines different risk measure oversteps. The stress signals of the past nine years on the German stock market were analyzed. The authors investigated the connection between the chosen stress measures to obtain a robust measure for alarming stress.

Findings
Although extreme returns and illiquidity are both characteristics of stress, the correlation of returns- and liquidity-based stress indicators is low when taking daily values. On the other hand, the moving averages of the indicators correlate significantly in the case of measures of downward and upward extreme returns and liquidity measured by the relative spread. The results are robust enough to be used for monitoring stress periods.

Originality/value
This paper contributes to understanding the characteristics of stress periods and points to the fact that stress signals measured by different aspects can also differ within the same asset class. The moving averages of returns- and relative spread-based indicators, however, could provide a cost-effective quantitative support for the risk management of a CCP and make the margin calculation predictable for clearing members as well.
Investment performance and emotions: an international study
Authors: Kaplanski Guy , Levy Haim 
Published: May 2019

Purpose
The purpose of this paper is to expand the peer effect analysis to investments in the stock market, where neither direct competition nor interaction with other investors exists.

Design/methodology/approach
A total of 772 subjects dwelling in six countries completed a questionnaire about their satisfaction with the performance of their hypothetical investment in the stock market. They were informed about the performance of the local stock market and the performance of their peer group, referred to in the questionnaire as their “friends.”

Findings
Only 5 per cent of subjects are indifferent to their friends’ investment performance, as advocates by expected utility paradigm. Most subjects are happier when their friends earn lower rather than higher returns. On average, subjects are better off losing rather than gaining money as long as their friends lose more money, which violates the univariate monotonicity axiom. A negligible number of subjects exhibit a consistent favorable response, which is a necessary condition for pure economic altruism. Hostility is greater in less-wealthy countries. No link is found with regard to economic inequality.

Originality/value
This paper shows that when a conflict between absolute wealth and relative wealth arises, the latter dominates, even when the comparison is not with an opponent or a colleague but with the subject’s friends. The astonishing result is that subjects prefer having less wealth as long as their friends lose more, despite no direct competition between subjects as in ultimatum games and despite the performance being equal to market performance.

Authors: Wang Tao , Li Ping , Wang Mingfang , Yang DanDan , Shi Chaoyu 
Published: May 2019

Purpose
This paper proposes a design of an efficient and automated experimental platform for frequency modulated continuous wave (FMCW) radars. The platform can quickly flexibly generate the waveform that meets measurement requirements and significantly improve experimental efficiency.

Design/methodology/approach
This platform not only includes radio frequency devices but also integrates a programmable transmitter based on field programmable gate array. By configuring the waveform data, the experimental platform can generate waveforms with adjustable parameters and realize automatic emission, reception and processing of signals. Different from traditional fast Fourier transform, this paper uses a discrete-time Fourier transform to process low-frequency signals to get more accurate results.

Findings
The authors demonstrate the effectiveness of the platform through a single-path cable experiment, an indoor ranging experiment by using different modulating waveforms and a speed measurement experiment. With complete functions and strong flexibility, the platform can operate effectively in various conditions and greatly improve the efficiency of research and study.

Practical implications
The platform can accelerate the research studies and applications of FMCW radars in the fields of automatic drive, through-wall detection and health-care applications.

Originality/value
Cost and functionality are taken into account in the platform, which can significantly improve the efficiency of research. The proposed signal processing method improves the accuracy while its computation complexity does not increase significantly.
The effects of microcrystalline cellulose on the flammability and thermal behaviours of flame retarded natural fibre epoxy composite
Authors: Khalili Pooria , Liu Xiao Ling , Tshai Kim Yeow , Kong Ing , Rudd Chris , Yi Xiao Su 
Published: May 2019

Purpose
The purpose of this paper is to fabricate and characterize the natural fibre (NF) reinforced epoxy composites containing flame retardants (FRs) and microcrystalline cellulose (MCC) in terms of flammability, thermal properties and dynamic mechanical performances.

Design/methodology/approach
The FRs used in this study were ammonium polyphosphate and alumina trihydrate.

Findings
The results demonstrated that the addition of MCC particles into the flame retardant composite (control) further enhanced the self-extinguishing properties of composites, in particular, the burn length. Thermogravimetric analysis showed that the mass residue improved with every addition of MCC particles at 700 °C. For instance, the residual weight enhanced from 28.4 Wt.% to 33 Wt.% for the control and the composite with 7 Wt.% MCCs, respectively. As obtained from the dynamic mechanical analysis, the glass transition temperature of composites increased upon increasing inclusion of MCC particles. For example, this parameter was 77.1 °C and 86.8 °C for the control and composite loaded with 7 Wt.% MCC, respectively.

Originality/value
Thus, the combination of MCC and FR had been proved to be a promising flame retardant system for NF reinforced epoxy.
Study on flexural performance of fabricated natural fiber hybrid polypropylene composite: an experimental investigation through designed experiments
Authors: Kumar Rajendra , Singh Ravi Pratap , Kataria Ravinder 
Published: May 2019

Purpose
This paper aims to investigate the flexural properties i.e. the flexural strength and the flexural modulus under the influence of selected input variables, namely; fiber type, fiber loading and fiber size in fabricated natural fiber polymeric composites through using Taguchi’s design of experiment methodology.

Design/methodology/approach
The Taguchi’s design of experiment approach has been used to scheme a suitable combination to fabricate the polymeric composites. Pure polypropylene (PP) has been chosen as a matrix material, whereas two types of fibers, namely; wood powder (WP) i.e. sawdust and rice husk powder (RHP), have been used as a reinforcement in the matrix. Microstructure analysis of fabricated and tested samples has also been evaluated and analyzed using a scanning electron microscope. This analysis has divulged that at moderate fiber size and higher fiber loading, no gap or cavities presented between the fillers and matrix particles, which illustrates the good interfacial bonding between the materials.

Findings
The flexural strength of the wood powder pure polypropylene (WPPP) composite decreases if the fiber content gets increased beyond 20 Wt.%. In addition, the flexural strength of hybrid composite (WPRHPPP) has been revealed to get improved more in comparison to composites with single fiber as reinforcement. Furthermore, the flexural modulus of WPPP composite has also increased with the increase in fiber loading. It has been concluded that reinforcement size plays an imperative role in influencing the flexural modulus. The optimum parametric setting for the flexural strength and the flexural modulus has been devised as; fiber type – WPRHP, fiber loading – 10 Wt.% and fiber size – 600 µm; and fiber type – WP, fiber loading – 30 Wt.% and fiber size – 1,180 µm, respectively. The microstructure images clearly revealed that during conducted flexural tests, some particles get disturbed from their bonded position that mainly represents the plastic deformation.

Social implications
The fabricated polymer materials proposed in the research work are green and environmentally friendly.

Originality/value
The natural fiber-based composites are possessing wide-spread requirements in today’s competitive structure of manufacturing and industrial applications. The fabrication of the natural fiber-based composites has also been planned through the designed experiments (namely; Taguchi Methodology- L9 orthogonal array matrix), which, further, makes the analysis more fruitful and qualitative too. The fabricated polymer materials proposed in the research work are green and environmentally friendly. Shisham WP has been rarely used in the past researches; therefore, this factor has been included for the present work. The injection molding process is used to fabricate the three different polymer composite by varying the fiber weight percentage and fiber size.
Seismic behavior evaluation of zipper braced steel frames based on push-over and incremental dynamic analyses
Authors: Esfandiari J. , Khezeli Y. 
Published: May 2019

Purpose
An analytical investigation is performed on zipper-braced frames. Zipper-braced frames are an innovative bracing system for steel structures. Conventional inverted-V-braced frames exhibit a design problem arising from the unbalanced vertical force generated by the lower story braces when one of them buckles. This adverse effect can be mitigated by adding zipper columns or vertical members connecting the intersection points of the braces above the first floor.

Design/methodology/approach
This paper critically evaluates over strength, ductility and response modification factors of these structures. To achieve the purpose of this research, several buildings of different stories are considered. Static pushover analysis, linear dynamic analysis and nonlinear incremental dynamic analysis are performed by OpenSees software concerning ten records of past earthquakes.

Findings
Also, ductility factor, over strength factor and response modification factor, has been calculated for zipper-braced frames system. The values of 3.5 and 5 are suggested for response modification factor in ultimate limit state and allowable stress methods, respectively.

Originality/value
The fragility curves were plotted for the first time for such kind of braces. It should be mentioned that these curves play significant roles in evaluating seismic damage of buildings.

SummaryThe Skp1‐Cul1‐F‐box‐protein (SCF) ubiquitin ligases are important parts of the ubiquitin system controlling many cellular biological processes in eukaryotes. However, the roles of SCF ubiquitin ligases remain unclear in phytopathogenic Magnaporthe oryzae. Here, we cloned 24 F‐box proteins and confirmed that 17 proteins could interact with MoSkp1, showing their potential to participate in SCF complexes. To determine their functions, null mutants of 21 F‐box‐containing genes were created. Among them, the F‐box proteins MoFwd1, MoCdc4 and MoFbx15 were found to be required for growth, development and full virulence. Fluorescent‐microscopy observations demonstrated that both MoFbx15 and MoCdc4 were localized to the nucleus, compared with MoFwd1, which was distributed in the cytosol. MoCdc4 and MoFwd1 bound to MoSkp1 via the F‐box domain, the deletion of which abrogated their function. Race tube and qRT‐PCR assays confirmed that MoFwd1 was involved in circadian rhythm by regulating transcription and protein stability of the core circadian clock regulator MoFRQ. Moreover, MoFWD1 also orchestrates conidial germination by influencing conidial amino acids pools and oxidative stress release. Overall, our results indicate that SCF ubiquitin ligases play indispensable roles in development and pathogenicity in M. oryzae.

Authors: Wen Jing , Zhang Jianhua , Hao Yongqing 
Published: May 2019

In this study, ELISA and PCR were used to examine paired serum and milk samples (n = 850) from China and milk samples (n = 860) from the Inner Mongolia Autonomous Region from 2008 to 2015. The annual proportion of Mycoplasma bovis‐positive mastitis samples in China and Inner Mongolia Autonomous Region fluctuated inexplicably, with total average positivity value of 53.0% and 34.2%, respectively. We propose that the monthly variation in the proportion of M. bovis‐positive mastitis milk in Inner Mongolia Autonomous Region is related to the pathogen's survival in the environment, which requires further confirmation. The results highlight the severity of M. bovis infection in clinical mastitis in China.
Comparison of heat stability of cow's milk subjected to ultra‐high temperature and in‐container sterilisation
Authors: Chen Bi Ye , Ren Fei Yue , Grandison Alistair S , Lewis Michael J 
Published: May 2019

Cow's milk of different fat contents with or without stabilising salts was sterilised by in‐container and UHT sterilisation. Heat stability decreased with increasing fat content following both UHT and in‐container sterilisation. Adding small amounts of stabilising salts (6.4 mM) increased heat stability in UHT‐treated milk, while excessive addition (12.8 mM) decreased heat stability. In contrast, increasing stabilising salts from 6.4 to 12.8 mM caused a decrease in heat stability after in‐container sterilisation. Increasing in‐container sterilisation time from 10 to 30 min caused a decrease in heat stability arising from an increase in particle size. This study confirmed discrepancies in heat stability for two sterilisation procedures.

AbstractIntroductionTo clarify the efficacy and safety of hypofractionated proton beam therapy (PBT) for centrally located lung cancer.MethodsWe retrospectively reviewed 39 patients who received hypofractionated [≧3 Gy (relative biological effectiveness: RBE)/fraction] PBT for centrally located cT1‐2N0M0 (8th edition) lung cancer between 1999 and 2015. A tumour within 2 cm of the proximal bronchial tree was defined as a centrally located tumour.ResultsTwenty‐four patients (62%) were treated with 80 Gy (RBE) in 20 fractions (112 Gy10), whereas eight (21%) were treated with 66 Gy (RBE) in 10 fractions (109.56 Gy10). The median follow‐up period for censored patients was 48 months (range: 4–140). The 2‐year progression‐free survival (PFS) and overall survival (OS) rates were 86 and 100% for T1 disease and 56 and 94% for T2 disease, respectively. Patients who received 110 Gy10 or higher showed significantly better PFS than those who received less than 110 Gy10, while no significant difference was noted in OS between the two groups. The sites of the first progression were local in six patients (27%), regional in seven (32%), distant in seven (32%), and local and distant in two (9%). Among the 13 patients with loco‐regional recurrence, only two (15%) received treatments with curative intent. Dyspnoea of grade 3 was noted in one patient (3%), and pneumonitis of grade 2 was noted in four patients (10%).ConclusionHypofractionated PBT may be a very safe and effective treatment option for centrally located early lung cancer.
