Modelling and hovering control for a coaxial unmanned helicopter using sliding mode
Authors: Chen Zhi , Wang Daobo , Zhen Ziyang 
Published: July 2018

Purpose
To facilitate the nonlinear controller design, dynamic model of a novel coaxial unmanned helicopter (UH) is established and its coupling analysis is presented.

Design/methodology/approach
The chattering-free sliding mode controller (SMC) with unidirectional auxiliary surfaces (UASs) is designed and implemented for the coaxial ducted fan UH.

Findings
The coupling analysis based on the established model show severe coupling between channels. For coaxial UH’s special model structure, UAS-SMC controller is proposed to reduce the coupling characteristics between channels of the UH by setting controllers’ output calculation sequence.

Originality/value
The flight control law and control logic are successfully tested in numerical simulation and hardware in the loop (HIL) simulation. The results show best hovering performances without chattering problem, even under the bounded internal dynamics and external disturbances.

Published: July 2018

Purpose
The purpose of this paper is to evaluate gender-related differences in the use of drugs for chronic diseases in undocumented migrants.

Design/methodology/approach
The authors analyzed the databases of two charitable organizations providing medical help and medicines to undocumented migrants. Data were available for 9,822 patients in the period 2014–2016. The authors grouped medicines according to the Anatomical Therapeutic Chemical (ATC) classification. We considered the ATC group as an indicator of a group of diseases.

Findings
Both males and females needed medicines for chronic diseases in a comparable manner. When we analyzed the age distribution, The authors noticed that males showed a tendency to begin to be affected at an earlier age; however, this cumulative difference was not statistically significant. But when we looked at six groups of drugs separately (cardiovascular, respiratory, anti-thrombotic, neurologic, psychiatric, anti-diabetic), the authors found that females always needed drugs for chronic diseases at a later age, always with a significant difference (p<0.0001 for cardiovascular, antithrombotic, antidiabetic and psychoactive drugs; p<0.002 for neurologic products; p<0.04 for drugs used in chronic respiratory conditions).

Research limitations/implications
This is a retrospective study based on the analysis of existing databases, but the peculiar features of this population (undocumented migrants) do not allow at the moment controlled studies.

Practical implications
Our observations could be important when planning public health strategies, especially in the field of prevention.

Originality/value
This is the first report of gender differences in the use of medicines for chronic diseases within a large sample of undocumented migrants.
Understanding how to succeed with project partnering
Authors: Nevstad Kristina , Børve Sjur , Karlsen Anniken Th , Aarseth Wenche 
Published: July 2018

Purpose
The purpose of this paper is to present new findings to organizations that acknowledge difficulties in implementing and succeeding with project partnering.

Design/methodology/approach
The investigation is based on a case study where empirical evidence has been collected via semi-structured interviews of 54 professionals within the construction industry.

Findings
Based on the research the authors were able to identify three main dimensions vital for project partnering success: 1. who related to participant selection; 2. what related to task clarification; and 3. way related to partnering means. These dimensions give rise to what the authors have termed a 3W (Who, What, Way) model on how to succeed with project partnering in practice. The third dimension, way related to partnering means, was found to consist of the four subdimensions: 3a. partnering attitude; 3b. a collaborative culture; 3c. a holistic perspective; and 3d. an accurate handover.

Originality/value
The authors found 318 papers focusing on partnering, in these only 19 focused on how to succeed with project partnering. The authors have complemented the limited research on how to succeed with project partnering with 54 interviews of professionals. The majority of the existing research has focused on challenges. This paper contributes to the research gap by presenting a 3W model on how to succeed with project partnering.
The impact of experiential augmented reality applications on fashion purchase intention
Authors: Watson Anna , Alexander Bethan , Salavati Leyla 
Published: July 2018

Purpose
Utilizing the stimulus-organism-response model, the purpose of this paper is to examine the effects of augmented reality (AR) (specifically augmentation) on consumers’ affective and behavioral response and to assess whether consumers’ hedonic motivation for shopping moderates this relationship.

Design/methodology/approach
An experiment using the manipulation of AR and no AR was conducted with 162 participants aged between 18 and 35. Participants were recruited through snowball sampling and randomly assigned to the control or stimulus group. The hypothesized associations were analyzed using linear regression with bootstrapping.

Findings
The paper demonstrates the benefit of using an experiential AR retail application (app) to positively impact purchase intention. The results show that this effect is mediated by positive affective response. Furthermore, hedonic shopping motivation moderates the relationship between augmentation and the positive affective response.

Research limitations/implications
Because of the chosen research approach, the results may lack generalizability to other forms of augmentation. Therefore, researchers are encouraged to test the proposed model using different types of AR stimuli. Furthermore, replication of the study with other populations would increase the generalizability of the findings.

Practical implications
Results of this study provide a valuable reference for retailers of the benefits of using AR when attempting to optimize experiential value in online environments.

Originality/value
The study contributes to experiential retail and consumer purchase behavior research by deepening the conceptualization of the impact of experiential technologies, more specifically AR apps, by considering the role of hedonic shopping motivations.
Improving service-center employees’ performance by means of a sport sponsorship
Authors: Wagner Ulrik , Hansen Kristian Rune , Kristensen Mette Lund , Josty Malene 
Published: July 2018

PurposeSponsorships targeting an internal audience, e.g. employees, are still under-researched. The purpose of this paper is to investigate how employees perceive and evaluate a sponsorship that is designed with the purpose of improving customer services and explore how the company may benefit from the sponsorship.Design/methodology/approachThe study is anchored in critical realism and based on a single case study using multiple methods. The authors survey the impact of the sponsorship on employees’ (n=653) perceptions of their ability to communicate with customers, to perform their personal best, to engage in teamwork, as well as employee retention. The authors use individual and group interviews to qualify the analysis and the access to company data on customer satisfaction rates to provide an indication of the effect of the sponsorship.FindingsResults indicate that close to half the employees respond that the campaign positively impacted their ability to communicate, improve personal performance and to engage in teamwork. The analysis also reveals that the commitment of the direct leader has an impact on employees’ interest and commitment to the campaign. Data on customer satisfaction show that reducing the number of dissatisfied customers and increasing the number of customers willing to recommend the company to others has been accomplished, thus indicating that the sponsorship has had a positive impact on company performance.Originality/valueBy combining sponsorship research with insights from the HRM literature, the study provides empirically based knowledge to the hitherto limited research on the internal audience of sponsorships. The study provides a plausible indication of a positive relation between a sponsorship design and company performance.
Are Islamic banks different? The application of the Radical Affinity Index
Authors: San-Jose Leire , Cuesta Jon 
Published: July 2018

Purpose
The purpose of this paper is to extend the literature on Islamic banking by examining their ethical dimension using transparency, placement of assets, guarantees and participation from Radical Affinity Index.

Design/methodology/approach
To this end, a sample of 20 Islamic banks from 13 countries (Bahrain, Saudi Arabia, Malaysia, Pakistan, Kuwait, Tanzania, Great Britain, Oman, Iraq, Egypt, Bangladesh and Qatar) was used.

Findings
The results are robust to ethical effects. The evidence suggests that among Islamic banks, at least some of them could improve their ethical requirements of the Sharia; they obtained lower scores than ethical banks in terms of RAI variables (transparency, placement of assets, guarantees and participation).

Research limitations/implications
It is used a random sample rather than population with the limitations that entails. The variables in the index are based on ethical perspective; then, the index is applied in Islamic banking but with the ethical view limitation.

Practical implications
The Islamic banks have the option to increase their transparency including further information regarding the beneficiaries of the benevolent funds; moreover, it would offer a clearer view about their ethical and social commitment towards society.

Originality/value
Additionally, this paper broadens the scope of the literature by analysing the determinants of Islamic banking around ethical dimensions of financial entities.
International-market-information use across new-product-development stages
Authors: Dubiel Anna , Banerjee Sourindra , Ernst Holger , Subramaniam Mohan 
Published: July 2018

PurposeThe purpose of this paper is to investigate how firms can better manage new product development (NPD) for international markets (IMs). This is not a trivial task as, for most firms, NPD still tends to be rooted in domestic operations.Design/methodology/approachThis study proposes IM information (IMI) use across three stages of the NPD process (concept development, product development and commercialization) as a key driver of international NPD performance. This study also examines two antecedents of such usage: international firm experience; and international innovation culture. A conceptual framework is tested using structural equation modeling, based on data from 137 strategic business units of German firms.FindingsThe use of IMI during commercialization has a U-shaped (positive quadratic) relationship with international NPD performance, whereas curvilinear relationships in the concept and product-development stages cannot be confirmed. Having an internationally oriented innovation culture increases the level of IMI usage in all NPD process stages, while a firm’s international experience only does so in the commercialization stage. Thus, international experience does not necessarily impact access to and understanding of IMI in the early NPD stages.Research limitations/implicationsThis study furthers understanding of NPD phenomena in an international context. However, future studies might consider exploring the mixed patterns of IMI use and NPD performance by looking at new forms and tools of market information management. Moreover, they may uncover more drivers of IMI use and test their frameworks in different contexts.Practical implicationsManagers should emphasize IMI use throughout the whole NPD process, even in the traditionally more R&D-focused product-development stage. Managers should strive to establish a corporate culture that views IMs as opportunities rather than liabilities.Originality/valueThis is the first study both to examine the relative impact of IMI use across all distinct NPD stages simultaneously on international NPD performance and to use quadratic effects to explain the relationship.
Commercialization behaviour in production agriculture
Authors: Yaseen Asif , Bryceson Kim , Mungai Anne Njeri 
Published: July 2018

Purpose
The purpose of this paper is to investigate the impact of market orientation (MO) on the major determinants of commercialization behavior among Sub-Saharan smallholders. The study addresses the shortfalls in prior research on smallholder commercialization, which makes little difference between MO and market participation (MP).

Design/methodology/approach
The study reports on an empirical data set of 272 vegetable growers from Kiambu West District in Kenya and employs a partial least squares structural equation approach to test the hypotheses.

Findings
The results evidence that MO: fosters farmers’ ability to create value within commodity markets by capitalizing on market opportunities; changes the way in which farmers perceive the role of institution and infrastructure support and; and develops a drive for adopting business approach in farming operations.

Research limitations/implications
Fostering commercialization behavior among smallholders in Kenya requires implementing a two-pronged approach: improving MO to adopt business approach in farming operations; and facilitating MP at output level. The major limitation of this study is data collected only from high value vegetable producers in Kenya, signifying a need to include other agriculture produce across different Sub-Saharan countries.

Originality/value
Research on smallholder agriculture is replete with investigating institutional and technical constraints to make smallholders more productive, however, research on MO to adopt business approach in farming operations is scant. This study emphasizes that understanding MO, as a distinct and separate concept from MP, is vital for scaling up business approach among smallholder farmers.

Published: July 2018

PurposeThis exploratory study aims to analyse the influence of organisational resources and capabilities on relationship quality and firm performance in the context of high-technology offshore outsourcing service vendors.Design/methodology/approachUsing a qualitative case study design, data from four offshore business process and information technology outsourcing firms were analysed.FindingsFindings highlight that resource dependence, cultural orientation and the vendor’s resources and capabilities strengthen relationship quality and affect firm performance.Originality/valueThe distinctive contribution of this study lies in identifying key organisational mechanisms that improve relationship quality and firm performance, as well as help to understand the adverse effects of ethnocentricity and power faced by vendors and subsidiaries within diverse intercultural contexts. Study limitations and future research directions, along with implications for theory and practice, are also discussed.
Psychological entitlement, egoistic deprivation and deviant behavior among cabin crews: an attribution theory perspective
Authors: Vatankhah Sanaz , Raoofi Ali 
Published: July 2018

PurposeThis study aims to report on the impact of psychological entitlement and egoistic deprivation on interpersonal and organizational deviant behavior among cabin crews. As a neglected theory in organizational research, attribution theory is used to link psychological entitlement to interpersonal and organizational deviant behavior through the mediating effect of egoistic deprivation.Design/methodology/approachA questionnaire survey was conducted in governmental and public airline companies in Iran. The survey yielded 294 effective questionnaires. Study relationships were gauged using structural equation modeling.FindingsAccording to the results, psychological entitlement boosts cabin crews’ egoistic deprivation and interpersonal and organizational deviant behavior. Consistent with hypothesized proposition, cabin crews’ egoistic deprivation fosters interpersonal deviant behavior. Particularly, it appears that egoistic deprivation among cabin crews partially mediates the effect of psychological entitlement on interpersonal deviant behavior. Contrary to the authors’ prediction, egoistic deprivation does not act as the mediator in the relationship between psychological entitlement and organizational deviant behavior.Originality/valueThis study sheds light on relatively limited psychological entitlement literature by extending attribution theory to cabin crews’ deprivation and workplace deviant behavior.
Incidence of Stevens–Johnson syndrome following combination drug use of allopurinol, carbamazepine and phenytoin in Taiwan: A case–control study
Authors: Syu Fei‐Kai , Pan Hsiu‐Yung , Chuang Po‐Chun , Huang Yi‐Syun , Cheng Chi‐Yung , Cheng Fu‐Jen 
Published: July 2018

AbstractThe goal of our study was to investigate the incidence of Stevens–Johnson syndrome (SJS), the frequency of SJS diagnosis, and the association between SJS and prior use of allopurinol, carbamazepine or phenytoin. This case–control study utilized data from the National Health Insurance Research Database (NHIRD) of Taiwan. Controls visited the emergency department of the same hospital for trauma or fractures (excluding burns) and used allopurinol, carbamazepine or phenytoin during the past 3 months. We determined whether patients were prescribed a combination of drugs in addition to allopurinol, carbamazepine or phenytoin within the last 3 months. We identified 1 853 985 controls and 7327 SJS‐diagnosed patients using the Taiwan NHIRD records for 2000–2008. Higher use of allopurinol (49.8%), carbamazepine (39.1%) or phenytoin (21.3%) was observed among patients (n = 3131) than among controls (n = 2858). The overall SJS incidence rate was 3.6/1 000 000. Drug combinations were uncommon (<10%) in patients or controls taking allopurinol. However, combination drug use exceeded 10% in patients taking carbamazepine or phenytoin. Logistic regression analysis of recent combination drug use revealed that phenobarbital, valproate, non‐steroidal anti‐inflammatory drugs (NSAIDs) including piroxicam and tenoxicam, and antibiotics including amoxicillin and cephalexin were strongly associated with SJS. Patients with gout or epilepsy taking allopurinol, carbamazepine or phenytoin should be evaluated carefully by physicians. Concurrent use of piroxicam, tenoxicam, phenobarbital, valproate, amoxicillin or cephalexin, in addition to carbamazepine or phenytoin, may increase the incidence of SJS.
Effect of salinity on seed germination and seedling growth of the halophyte Suaeda japonica Makino
Authors: Haraguchi Akira , Matsuda Tomoko 
Published: July 2018

AbstractSeed germination and seedling growth of the annual halophyte species Suaeda japonica Makino were investigated in response to variable salinity of sediment pore water. The germination percentage of S. japonica’s soft brown seeds, which are dominant among dimorphic seeds, decreased with an increase in salinity, although germination was still observed at 1200‐mM NaCl concentration. The germination percentage and germination speed observed in April were higher than those observed in December when treated with sediment water with 400–1200 mM of NaCl concentrations. These data suggest that S. japonica seedlings could be established on sediments that experience high temperatures. Germination recovery of S. japonica seeds transferred from 600‐mM NaCl containing sediment (seawater equivalent) was lowest among 0–1200‐mM NaCl treatments, implying the low tolerance of seawater conditions of S. japonica seeds. Seeds germinated in 900‐ to 1200‐mM NaCl medium showed poor growth, but survived, in hypersaline conditions, and exhibited improvement in growth upon transfer to lower salinity.
The making of an egalitarian elite: school ethos and the production of privilege
Authors: Törnqvist Maria 
Published: July 2018

AbstractResearch on privilege and education often focuses on institutions that are elite in a rather traditional way, for example schools that instruct the children of the upper classes according to a reproductive logic that reinforces existing inequalities. The present article addresses the fostering of advantage from the angle of a more ambiguous case. The Global College, a municipal Swedish upper secondary school specialized in environmental issues and global justice, offers an empirical prism for discussing the cultivation of elite identification through the formative potential of an egalitarian ethos. The relation between ethics and class is examined, not only in terms of how moral stands are classed, but also by investigating into the productive capacities of such orientation. Through extensive ethnographic fieldwork, the study unfolds how a possible tension between egalitarianism and elitism resolves into a productive relation whereby the students’ incarnation of ethico‐political ideals becomes a means for developing agency, confidence, entrepreneurial skills and an overall sense of ease.

Published: July 2018

IntroductionMillions of patients undergo major abdominal surgery worldwide each year, and the post‐operative phase carries a high risk of respiratory and circulatory complications. Standard ward observation of patients includes vital sign registration at regular intervals. Patients may deteriorate between measurements, and this may be detected by continuous monitoring. The aim of this study was to compare the number of micro events detected by continuous monitoring to those documented by the widely used standardized Early Warning Score (EWS).MethodsFifty patients were continuously monitored with peripheral arterial oxygen saturation (SpO2), heart rate (HR), and respiratory rate (RR) the first 4 days after major abdominal cancer surgery. EWS was monitored as routine practice. Number and duration of events were analyzed using Fisher's exact test and Wilcoxon rank sum test.ResultsContinuous monitoring detected a SpO2 <92% in 98% of patients vs 16% of patients detected by EWS (P < .0001). Micro events of SpO2 <92% lasting longer than 60 minutes were found in 58% of patients by continuous monitoring vs 16% by the EWS (P < .0001). Fifty‐two percent of patients had micro events of SpO2 <85% lasting longer than 10 minutes. Continuous monitoring found tachycardia in 60% of patients vs 6% by the EWS. Frequency of events for bradycardia, tachypnea, and bradypnea showed similar patterns.ConclusionVery low SpO2 and tachycardia in post‐operative patients are common and under‐diagnosed by the EWS. Continuous monitoring can discover these micro events and potentially contribute to earlier detection and, potentially, result in prevention of clinical complications.
