Design of composite landing gear for an LSA airplane
Authors: Cejpek Jakub 
Published: April 2018

Purpose
The purpose of this paper is to introduce a software tool under development by the author. Based on industry demands, a software tool is developed to fill the gap between commercial software and limited closed-form analysis in this specific area.

Design/methodology/approach
Python programming language offers a great potential to develop relatively simple software that includes graphical user interface and can be turned into an executable file – therefore easily spread. Also, thanks to large community, Python offers extended scientific libraries for solving number of engineering problems. Results are compared to the commercially available software (in this case, MSC NASTRAN). Further evaluation is done to compare results to the laboratory tests.

Findings
First results were obtained from the comparison between KuFEM and NASTRAN. These results are sufficient reassurance for next stages of development. Next results are the comparison of KuFEM results to the laboratory test. As only one type of product has been tested, no final conclusion can be made. However, within these limits, the results are very promising and optimistic.

Research limitations/implications
Future development will include further evaluation on different products, even more composite-oriented calculations, enhanced graphical environment.

Practical implications
KuFEM, within its limits, is an alternative to other commercial programs. It is meant to compromise between limited closed-form designs and detailed designs in expensive software.

Originality/value
KuFEM is a unique software tool. It allows user to work with finite element method in a simple preprogrammed way. It enhances the standard BEAM elements to go deeper in the analysis. Currant evaluation promises potential good results.
Experimental investigations into parachute rescue systems
Authors: Rodzewicz Miroslaw , Glowacki Dominik , Szczepanik Tomasz , Hajduk Jaroslaw 
Published: April 2018

Purpose
The purpose of this paper is to describe the results of investigations of parachute rescue systems (PRS) for light gyrocopters.

Design/methodology/approach
Although the investigations were conducted in both stages simultaneously, i.e. experimental mechanics approach and numerical simulations, the paper is focussed mainly on the experimental part of the work. To ensure the safety of experimental works (i.e. for both experimenters and bystanders), the authors applied unmanned, remotely controlled scale models of autogyro for the PRS testing in the air.

Findings
The critical problem for successful use of the PRS is that the rotation of the rotor blades must be stopped when the main parachute opens, otherwise the influence of the rotor on the improper opening process of the parachute may cause the whole PRS to become useless.

Research limitations/implications
The existing regulations for the use of unmanned aircraft impose the limitation upon the organisation of in-flight tests of PRS, i.e. the maximum take-off mass of the tested gyrocopter models is limited, and a full-scale test needs the approval of European Aviation Safety Agency (EASA).

Practical implications
The research contributes to increasing the safety level for gyrocopter users. The authors elaborated the original PRS, which currently is in the process of patenting.

Originality/value
Originality of the work consists of both an innovative PRS, which has never been tested before, and the results of experimental investigations, which cover both ground tests carried on static or moving stands and in-flight testing.
The effects of competitive reserve prices in online auctions
Authors: Han Jidong , Qiu Chun , Popkowski Leszczyc Peter 
Published: April 2018

Purpose
This paper aims to investigate how competition among online auction sellers influences the setting of both open and secret reserve prices, thereby affecting auction outcome.

Design/methodology/approach
Using a data set collected from eBay consisting of 787 identical product auctions, three empirical models have been proposed. Model 1 simultaneously estimates the effects of auction competition on a seller’s own open and secret reserve price strategies; Model 2 estimates the effects of auction competition on bidder participation; and Model 3 estimates the direct and indirect effects of auction competition on selling price.

Findings
Competition among sellers is central to shaping sellers’ reserve price strategies. When there are more concurrent auctions for identical items, sellers tend to specify a low open reserve and are less likely to set a secret reserve. Sellers are strongly influenced by competitors’ reserve price strategies, and tend to follow competition. Finally, auction competition and competitive reserve price strategies influence both bidder entry and selling prices.

Practical implications
This study has important implications for both sellers and bidders. It highlights the importance for sellers to adapt their reserve price strategies in light of their competitors’ reserve price strategies and offers implications for bidders regarding auction selection. An auction with low starting bid does not necessarily lead to a lower selling price as it attracts more bidders.

Originality/value
This paper focuses on competition among auction sellers, whereas previous literature has focused on competition among bidders. This paper is the first to study the impact of competing reserve prices in auctions.
“The ability to get a job”: student understandings and definitions of employability
Authors: Gedye Sharon , Beaumont Emily 
Published: April 2018

PurposeThe purpose of this paper is to explore employability in the context of higher education (HE) from the students’ perspective. Limited attention has been paid to student understandings of their own employability in a Sport Science context and Tymon (2011) refers to them as “the missing perspective”.Design/methodology/approachThis paper presents the findings of a study of Marine Sports Science students (n=63) at a post-1992 HE institution which through the qualitative element of a mixed methods survey explored their changing articulations of their employability as they progressed through their studies. The students surveyed were in receipt of a comprehensive programme of enterprise and employability activities embedded within their programme.FindingsQualitative results showed that Marine Sport Science students’ articulations of employability expanded in vocabulary as the students progressed through their studies. Definitions also shifted from those that centred on what employers want (extrinsic) to what the student had to offer the employer (intrinsic).Originality/valueThere are very few examples of studies that explore employability from the students’ perspective and this paper adds understanding on this “missing perspective”. It also addresses a specific discipline area; Marine Sport Science, which has yet to feature in any literature on employability.
Pay equity and marginalized women
Authors: Kohout Roopkiran , Singh Parbudyal 
Published: April 2018

Purpose
The purpose of this paper is to examine the experiences of marginalized women in achieving equal pay for work of equal value. The research focuses on Ontario, Canada, as this is a leading jurisdiction globally in implementing legislation on pay equity. It provides an opportunity to understand the lived experiences of women whom scholars have identified as particularly vulnerable in workplaces.

Design/methodology/approach
This is a qualitative research study. Twenty-three interviews were conducted with women defined as marginalized. Thematic analysis was used to analyze the data.

Findings
Three themes resulted from the analysis: early employment experiences, cultural challenges at work and inequities in pay. The authors found that not only do structural and organizational barriers limit the ability of marginalized women to achieve parity in the workplace but there also is a hidden social element that requires further investigation.

Originality/value
The gender pay gap is wider for marginalized women, even after three decades since pay equity legislation was implemented in Ontario. There is a dearth of research on why this is the case. This study adds to the literature by focusing on a broader set of factors, in addition to legislation, that must be considered when focusing on solutions to the gender pay gap.
Online physicians, offline patients
Authors: Au Anson 
Published: April 2018

Purpose
The purpose of this paper is to demonstrate how the nature, gravity, and consequences of physician use of social media use surpass professional identity, by bringing to attention the nuanced, potential conflicts between patient-physician interests in current educational policies.

Design/methodology/approach
Analyzing a case study of a physician publicly posting and commenting on many of his patients’ information, conversations, and medical conditions on social media.

Findings
Physician social media use carries many issues that concern ethics and the patient, rather than professional identity and the physician. In response, two sets of ethical standards are developed: one that deals with what constitutes impermissible behaviors online, and another that stipulates appropriate punishments for violations of these codes.

Originality/value
Most medical education policies and the literature have emphasized professional identity- formation with regards to physician use of social media, rather than ethics. Furthermore, no study exists that presents a clear, concrete, insider perspective at physicians’ improper use of social media.
A grey analytic hierarchy process approach to project manager selection
Authors: Çelikbilek Yakup 
Published: April 2018

Purpose
Evaluations of grey systems and systems with subjective judgements are always like an impasse for science and companies. Especially, calculations of the problems which include various units are really difficult situations. The purpose of this paper is to propose a grey analytic hierarchy process (G-AHP) for engineering and managerial problems with grey systems to make more clear and objective decisions.

Design/methodology/approach
Proposed G-AHP approach is applied to project manager selection for a software project of an energy company. The application includes three different units as year, score and assessment. Six engineers are evaluated with 25 criteria in the application. Weights of the factors and assessments are done by three top managers of the company as pairwise comparisons. Other data in the decision matrix are obtained from the personal information and exam results of engineers.

Findings
Final weights of the criteria and evaluations of engineers are all done with the proposed G-AHP. Obtained results of G-AHP are also compared with grey “VlseKriterijumska Optimizacija I Kompromisno Resenje” results as a validation of the calculations and proposed approach. Final results of the applications are ranked for the evaluations and comparison. All results of the case study are concluded with the effectiveness and applicability of the proposed G-AHP method both for this study and other fields of science, engineering and management.

Originality/value
This study provides to evaluate and interpret grey systems with different units and subjective judgements for science, engineering and management more clearly and objectively in an easier way.
Impacts of personal trust, communication, and affective commitment on change success
Authors: Ouedraogo Noufou , Ouakouak Mohammed Laid 
Published: April 2018

PurposeSuccessful change implementation is crucial for organizational prosperity, and even survival. The purpose of this paper is to examine the impacts of personal trust and communication on change success, through affective commitment.Design/methodology/approachBased on an empirical study conducted among 307 employees of Canadian organizations and using structural equation modeling techniques.FindingsThe authors find that communication has a direct impact on change success, as well as an indirect impact through affective commitment. Trust only exerts an indirect effect through affective commitment.Originality/valueThis research thus extends the literature on the role of “soft” organizational factors on organizational change. Since the authors have limited this study to “soft” variables, it can be complemented with a study of hard factors contributing to change success, in order to build a comprehensive organizational change success model.
The acceptance of technological change in the hospitality industry from the perspective of front-line employees
Authors: Montargot Nathalie , Ben Lahouel Béchir 
Published: April 2018

PurposeWhereas past research has been valuable in explaining how “perceived usefulness” (PU) and “perceived ease of use” (PEU) constructs lead to technology acceptance and refusal behaviors in organizations, it has not explored the antecedents of these two factors. The purpose of this paper is to propose an interpretive approach to the study of front-line employees’ sense making of technological change as well as the understanding of behavioral and psychological origins of PU and PEU.Design/methodology/approachThis study analyses a major transition in work mode induced by an IT innovation implemented within a leading French hospitality company. A qualitative method was employed to answer the research questions. The data were collected using 22 in-depth semi-structured interviews from front-line employees and their line managers in five 4-star hotels in Paris. The participants were asked how they made sense of the technological change and what they consider when they judge the usefulness and the ease of use during the implementation of change.FindingsThe analysis revealed that employees’ acceptance of technological change is paradoxical and shaped by a continuous process of sense making when using the IT innovation. The findings also suggest that PU can be explained by factors like job relevance, PEU and output quality. Anxiety, playfulness, perceived enjoyment, objective usability and facilitating conditions were identified as antecedents of PEU.Research limitations/implicationsThe paper reports the effect of perceptions of social influence, system characteristics, individual differences and facilitating conditions on PU and PEU constructs in IT adoption process. It is among the first to examine the antecedents of such beliefs in the hospitality industry through the use of a qualitative method. It also shows that that three variables – result demonstrability, computer self-efficacy and social influence process described by subjective norm and image – did not play a significant role in influencing the intensions of using the system through PU and PEU.Practical implicationsUnderstanding the antecedents of the two key predictors in technology acceptance models allows managers to implement efficient adjustments and interventions in order to positively influence employees’ IT innovation acceptance and use.Originality/valueThis qualitative study contributes to open the black boxes concerning the conceptualizations of PU and PEU. It advances the understanding of the employees’ acceptance of IT innovation.
PhD scientists in the boardroom: the innovation impact
Authors: Swift Tim 
Published: April 2018

PurposeThe purpose of this paper is to evaluate the impact that PhD scientists serving on the board of directors of firms conducting hard science have on the R&D-based innovative performance of the firm.Design/methodology/approachThe research hypotheses are built upon extant theory, and they are tested using two-stage least squared regression that control for the endogenous nature of board composition. Results are robust to alternative specifications.FindingsThis analysis shows that firms with higher numbers of PhD scientists on the board generate superior innovative output and more efficient monitoring; PhD board members with denser professional networks are more valuable as board members.Practical implicationsThis paper provides practical advice to innovative firms on how to create a governance process that simultaneously improves monitoring and boosts the innovative performance.Originality/valueThis study is the first one to suggest that innovative firms can improve R&D monitoring and boost innovative output at the same time, and the first to investigate the role that PhD scientists can serve on the board of firms engaging in hard science.
Learning from the future meets Bateson’s levels of learning
Authors: Kaiser Alexander 
Published: April 2018

Purpose
Previous studies showed that combining learning based on experiences in the past with learning from an envisioned future scenario results in more innovative and radical ideas, as well as in a higher number of covered content domains. However, currently there is no holistic learning theory that integrates both sources of learning. The main purpose of this paper is to investigate whether it is possible to extend Bateson’s theory of learning, to link these two learning sources in one coherent framework.

Design/methodology/approach
To answer this research question, the author draws on learning from an envisioned future, and tries to link it with the most important levels of learning in Bateson’s framework.

Findings
This paper contributes to the literature by attempting to link the important but still underexplored aspect of “learning from the future” to the complex and multifaceted work of Bateson. Given the fact that both sources of learning and experience yield a great potential to create new knowledge, this study outlines a possibility to include both sources into one learning theory.

Research limitations/implications
This work provides the basis for further research in building a general holistic theory of learning to learn.

Practical implications
On the individual level, the proposed approach can be easily applied with systemic coaching processes in general and coaching processes in the fields of developing an individual vision in particular. In the field of organizational learning, the awareness of different learning sources and different learning modes on the one hand and knowledge about the implementation of enabling spaces (PE-ba, FE-ba) to support these various learning modes on the other hand help organizations to generate new knowledge and create innovative and sustainable solutions, products and services.

Originality/value
To the best of the author’s knowledge, it is the first theoretical work that describes the integration of learning from past experiences and learning from future experiences in a methodological way.
Relationship between environmental factors, age of onset and familial history in Japanese patients with psoriasis
Authors: Bayaraa Bolortuya , Imafuku Shinichi 
Published: April 2018

AbstractPsoriasis is a chronic inflammatory disease that often involves the skin and joints. Psoriasis develops at any age and the distribution of age of onset of psoriasis is bimodal in Japan. Also, male predominance is distinct in Japanese psoriatic patients. To clarify the relationship between sex difference and habitual/environmental status, age and incidence of familial psoriasis, we analyzed data from the Fukuoka University Psoriasis Registry. A total of 1120 Japanese patients (751 men, 369 women) were analyzed. The male/female ratio was 2.03:1. Smoking and drinking habit, known as risk factors of psoriasis, were significantly more prevalent in men. Age‐specific psoriasis‐onset rate standardized by population showed bimodal distribution in both men and women; the younger peak was in their 30s for men and 10s in women; the second peak was in the 50s for both sexes. A familial history of psoriasis was seen in 6.3% of patients overall; however, female patients showed a significantly higher rate (8.7%) compared with men (5.1%, P = 0.024). When stratified by age of onset, the frequency of familial history was much higher among women with onset at less than 30 years (15.4%), compared with 30 years or more (5.3%, P = 0.0026). Our data suggest that genetic factors have a stronger influence in young women who experience fewer environmental factors such as smoking and drinking. This is the first study to show that there is a difference in the incidence of familial psoriasis depending on age of onset of psoriasis in Japan.
Comparative proteome analysis of propionate degradation by Syntrophobacter fumaroxidans in pure culture and in coculture with methanogens
Authors: Sedano‐Núñez Vicente T. , Boeren Sjef , Stams Alfons J. M. , Plugge Caroline M. 
Published: April 2018

SummarySyntrophobacter fumaroxidans is a sulfate‐reducing bacterium able to grow on propionate axenically or in syntrophic interaction with methanogens or other sulfate‐reducing bacteria. We performed a proteome analysis of S. fumaroxidans growing with propionate axenically with sulfate or fumarate, and in syntrophy with Methanospirillum hungatei, Methanobacterium formicicum or Desulfovibrio desulfuricans. Special attention was put on the role of hydrogen and formate in interspecies electron transfer (IET) and energy conservation. Formate dehydrogenase Fdh1 and hydrogenase Hox were the main confurcating enzymes used for energy conservation. In the periplasm, Fdh2 and hydrogenase Hyn play an important role in reverse electron transport associated with succinate oxidation. Periplasmic Fdh3 and Fdh5 were involved in IET. The sulfate reduction pathway was poorly regulated and many enzymes associated with sulfate reduction (Sat, HppA, AprAB, DsrAB and DsrC) were abundant even at conditions where sulfate was not present. Proteins similar to heterodisulfide reductases (Hdr) were abundant. Hdr/Flox was detected in all conditions while HdrABC/HdrL was exclusively detected when sulfate was available; these complexes most likely confurcate electrons. Our results suggest that S. fumaroxidans mainly used formate for electron release and that different confurcating mechanisms were used in its sulfidogenic metabolism.

AbstractAimTo evaluate the effect of tumor necrosis factor α inhibitors (TNFi) on spinal radiographic progression in patients with ankylosing spondylitis (AS).MethodsSubjects were selected from patients at a single tertiary hospital between 1995 and 2014. Patients who used TNFi with baseline and paired follow‐up radiographic data with a minimum interval of 2 years were included. Time to start TNFi was defined as the time from symptom onset to the start of TNFi use. TNFi index was defined as the ratio of the period of TNFi use to the entire period of disease. Radiographic damage was assessed by the modified Stoke Ankylosing Spondylitis Spine Score (mSASSS). Univariable and multivariable linear regression analyses were used to identify factors associated with radiographic progression.ResultsA total of 151 patients were included in the analysis. Seventeen (11.3%) patients were female and mean ΔmSASSS/year was 1.01 units/year. Mean X‐ray follow‐up duration was 102.9 ± 54.9 months. Mean time from symptom onset to start of TNFi use was 104.8 ± 83.6 months (median 84 months) and mean TNFi index was 42.9 ± 23.8% (median 40.9%). In multivariable analysis, initial mSASSS, initial C‐reactive protein, body mass index, current smoker, and delayed start of TNFi use were associated with radiographic progression. Presence of peripheral arthritis and the TNFi index were negatively associated with radiographic progression.ConclusionsA delay in starting TNFi use and low TNFi index were associated with radiographic progression. Early and long‐term use of TNFi appear to reduce spinal radiographic progression in patients with AS.
