Vision-based relative navigation using cubature Huber-based filtering
Authors: Chen Cheng , Wang Xiaogang , Qin Wutao , Cui Naigang 
Published: July 2018

Purpose
A novel vision-based relative navigation system (VBRNS) plays an important role in aeronautics and astronautics fields, and the filter is the core of VBRNS. However, most of the existing filtering algorithms used in VBRNS are derived based on Gaussian assumption and disregard the non-Gaussianity of VBRNS. Therefore, a novel robust filtering named as cubature Huber-based filtering (CHF) is proposed and applied to VBRNS to improve the navigation accuracy in non-Gaussian noise case.

Design/methodology/approach
Under the Bayesian filter framework, the third-degree cubature rule is used to compute the cubature points which are propagated through state equation, and then the predicted mean and the associated covariance are taken. A combined minimum l1 and l2-norm estimation method referred as Huber’s criterion is used to design the measurement update. After that, the vision-based relative navigation model is presented and the CHF is used to integrate the line-of-sight measurements from vision camera with inertial measurement of the follower to estimate the precise relative position, velocity and attitude between two unmanned aerial vehicles. During the design of relative navigation filter, the quaternions are used to represent the attitude and the generalized Rodrigues parameters are used to represent the attitude error. The simulation is conducted to demonstrate the effectiveness of the algorithm.

Findings
By this means, the VBRNS could perform better than traditional VBRNS whose filter is designed by Gaussian filtering algorithms. And the simulation results demonstrate that the CHF could exhibit robustness when the system is non-Gaussian. Moreover, the CHF has more accurate estimation and faster rate of convergence than extended Kalman Filtering (EKF) in face of inaccurate initial conditions.

Originality/value
A novel robust nonlinear filtering algorithm named as CHF is proposed and applied to VBRNS based on cubature Kalman filtering (CKF) and Huber’s technique. The CHF could adapt to the non-Gaussian system effectively and perform better than traditional Gaussian filtering such as EKF.

Authors: Lu Yanjun , Xiong Li , Zhang Yongfang , Zhang Peijin , Liu Cheng , Li Sha , Kang Jianxiong 
Published: July 2018

Purpose
This paper aims to introduce a novel four-dimensional hyper-chaotic system with different hyper-chaotic attractors as certain parameters vary. The typical dynamical behaviors of the new hyper-chaotic system are discussed in detail. The control problem of these hyper-chaotic attractors is also investigated analytically and numerically. Then, two novel electronic circuits of the proposed hyper-chaotic system with different parameters are presented and realized using physical components.

Design/methodology/approach
The adaptive control method is derived to achieve chaotic synchronization and anti-synchronization of the novel hyper-chaotic system with unknown parameters by making the synchronization and anti-synchronization error systems asymptotically stable at the origin based on Lyapunov stability theory. Then, two novel electronic circuits of the proposed hyper-chaotic system with different parameters are presented and realized using physical components. Multisim simulations and electronic circuit experiments are consistent with MATLAB simulation results and they verify the existence of these hyper-chaotic attractors.

Findings
Comparisons among MATLAB simulations, Multisim simulation results and physical experimental results show that they are consistent with each other and demonstrate that changing attractors of the hyper-chaotic system exist.

Originality/value
The goal of this paper is to construct a new four-dimensional hyper-chaotic system with different attractors as certain parameters vary. The adaptive synchronization and anti-synchronization laws of the novel hyper-chaotic system are established based on Lyapunov stability theory. The corresponding electronic circuits for the novel hyper-chaotic system with different attractors are also implemented to illustrate the accuracy and efficiency of chaotic circuit design.
Battered but bold: Sri Lankan Tamil refugee war experiences, camp challenges and resilience
Authors: Kuttikat Miriam , Vaillancourt Anita , Massey Michael 
Published: July 2018

PurposeThe civil war prompted many Tamils to flee Sri Lanka as refugees. Several researchers have documented psychological distress and trauma among Sri Lankan Tamil refugees, but the literature lacks sufficient discussion of resilience among this population. Although Sri Lankan Tamil refugees have experienced conflict and loss, they have also demonstrated positive adaptation following these challenges. The paper aims to discuss these issues.Design/methodology/approachThe present study used an ecological approach, in which the effect of the environment on a person is regarded as significant, to explore resilience among Sri Lankan Tamils living in refugee camps in India.FindingsThrough a qualitative investigation of refugee experiences of war and camp life, the authors developed a conceptual framework for understanding individual and collective resilience among refugees.Research limitations/implicationsAdditionally, the results of this study need to be interpreted with caution because participants were camp refugees, which may limit the applicability of these results with refugees who live in different settings.Practical implicationsThe current research results show that intervention programs should have multiple components, including trauma intervention to address the individual and community psychological and psychiatric effects of war and migration experiences and psychosocial interventions to address individual, family, community dynamics and daily stressors.Social implicationsThe study participants stated that Sri Lankan Tamil refugees are using their resilience traits including will power, positive talk, practical solutions, social support, religion and social networks to remake their broken souls.Originality/valueFuture studies need to be conducted with other refugee group to validate the findings of the paper.
Hyper academia
Authors: Munar Ana María 
Published: July 2018

Purpose
What ought we morally to do in a tourism academia dominated by metrics, quantification and digital codification? The purpose of this paper is to address this question by presenting the idea of “hyper academia” and exploring ethical perspectives and values related to hyper-digital cultures.

Design/methodology/approach
Drawing inspiration from classical and post-disciplinary traditions, the topic is exposed in a creative and multi-layered way using conceptual, philosophical and artistic tools. It is structured in four sections: An introductory essay on gratitude, a philosophical thought experiment, a literary short story and a manifesto.

Findings
Gratitude referencing is a method of personalizing the attribution of influence in scholarship and restoring the importance of depth and slowness over speed, novelty and quantity. The thought experiment allows us to see how we make value judgements on academic work under different scenarios. The dystopian short story shows the radical power that such a genre has to create emotional engagement whilst activating our critical reflexivity. Finally, the manifesto answers the question of what we morally “ought to do” by inviting scholars to engage with five duties.

Originality/value
This paper looks beyond previous descriptive studies of academic rankings and metrics, inviting tourism scholars to reflect on the values and moral justifications behind our evaluation cultures.
Exoskeletons – a review of industrial applications
Authors: Bogue Robert 
Published: July 2018

Purpose
This paper aims to provide details of the emerging families of robotic exoskeletons that are aimed at industrial applications.

Design/methodology/approach
Following an introduction, this paper considers the reasons for, and benefits of, using robotic exoskeletons in industrial applications. The paper then discusses a range of products and developments and their applications. Finally, brief concluding comments are drawn.

Findings
Following earlier military and medical developments, recent years have seen a huge upsurge in interest in industrial robotic exoskeletons. A new generation of products are under development in the USA, the Europe and the Far East by a growing number of companies, and some have entered production. The aim of developing industrial robotic exoskeletons is to assist workers in physically demanding tasks and, thus, reduce the incidence of industrial injuries and associated financial consequences. Several applications have been reported, most notably in the Far East, across a diverse range of industries.

Originality/value
New families of robotic exoskeletons are being developed, and these are poised to exert a major impact on many industries and constitute a significant market opportunity. This paper provides a timely insight into these developments.
Tariff barriers and industrial spillover effects
Authors: Kang Jong Woo , Dagli Suzette 
Published: July 2018

Purpose
The purpose of this paper is to demonstrate that higher tariffs under protectionism will have significant indirect impact through industrial forward and backward linkages, causing greater economic losses to tariff-imposing economies than to exporting countries.

Design/methodology/approach
The authors use partial equilibrium analysis based on unique multi-regional input-output (IO) data in measuring the second-round spillover effects of higher tariffs, also investigating the scenario of plausible substitutability across import sources as well as sectors based on historical import intensity data.

Findings
Higher tariffs do not only have a direct impact, but also a significant indirect impact—through forward and backward linkages. Indirect effects can be extensive across economies and sectors—both in forward and backward linkages such as in transport—when value chains are longer and more complex. When possible substitution effects between different import sources and sectors are considered, negative forward linkage effects can be smaller, while negative backward linkage effects become more pronounced. Nevertheless, both negative effects are still found to be much bigger in indirect impacts compared with direct impacts.

Research limitations/implications
This implies that higher tariffs, including administrative trade measures such as anti-dumping duties and countervailing duties could ironically entail rather greater negative impact on the tariff-imposing importing economies by damaging their exports of domestic sectors using the targeted imports as intermediate inputs, which could be severe if the importing sector has a long value chain in particular through deep forward linkages.

Originality/value
This paper uses unique multi-regional IO data covering 45 economies’ 35 sectors in analyzing the second-round spillover effects across countries and sectors and employs comparative statics under different scenarios.
SEC Enforcement: Self-Reporting Share Class Selection Disclosure Initiative
Authors: Greenberg Elaine 
Published: July 2018

Purpose
This paper aims to explain the U.S. Securities and Exchange Commission’s (SEC’s) recent Share Class Selection Disclosure (SCSD) Initiative, which offers potentially favorable settlement terms to investment advisers who self-report to the SEC’s Enforcement Division violations of the federal securities laws relating to certain mutual fund share class selection issues and to discuss factors for consideration by investment advisers regarding their possible participation in this initiative.

Design/methodology/approach
This paper discusses the conditions and terms of the SEC’s SCSD Initiative, the SEC’s focus on conflicts of interest associated with mutual fund share class selection, the applicable law, the complex nature of these issues and the factors that investment advisers should consider in determining whether to participate in the initiative.

Findings
The assessment of the facts and the evaluation and analysis of the issues may be both time-consuming and complex. Firms need to carefully consider whether the potential benefits of self-reporting outweigh any possible downsides, including the potential collateral consequences that an SEC enforcement action may have on their business operations.

Originality/value
This paper contains valuable information about a recent SEC Enforcement Initiative and provides practical guidance from experienced securities counsel.
Is it time for libraries to take a closer look at emoji? The data deluge column
Authors: Frederick Donna Ellen 
Published: July 2018

Purpose
The emoji, is it an endearing image to add to your text messages and email, or is it an increasingly important type of electronic data? According to a 2013 article by Jeff Blagdon, the idea of using some sort of symbol in electronic communication has been with us for about two decades. Japanese in origin, the earliest symbols of this type were developed in the era of pagers and old-style cell phones and were commonly called emoticons.

Design/methodology/approach
As devices developed a greater capacity to display graphical elements these keystroke representations were replaced with Unicode characters which display on our electronic devices, which we now call emoji. This instalment of the data deluge will look at the emoji as a form of data and explore how and why their ubiquity may create new opportunities for libraries.

Findings
Some readers, as well as the author of this column, may be tempted to scoff at the idea that the emoji is anything more than a form of shorthand for use in electronic communications or cutesy decorations.

Originality/value
One night she showed up at the class, and the instructor wrote on the board, “Computers in school libraries: A new tool or a flash in the pan?” He went on to warn school librarians to not be dazed by this “new computer phase” which he felt distracted both teachers and students from the real work of teaching and learning. He felt that if there were computers in schools, they only belonged in the mathematics classroom and that, even in that context, they only had limited application.
The “constant tug-of-war” in mental health care in Greece
Authors: Kyriakidou Niki , Triliva Sofia 
Published: July 2018

Purpose
The purpose of this paper is to focus on how mental health professionals involved in the therapeutic treatment of children in public mental health facilities in Greece experience and talk about the impact of the socioeconomic crises on the psychotherapeutic process.

Design/methodology/approach
In all, 21 semi-structured interviews were conducted and phenomenologically informed thematic analysis was used in analysing the data.

Findings
The results coalesced into two all-encompassing thematic structures articulating the following: first, the socioeconomic crises have permeated society and therapeutic praxis like a torrential and chronic rain storm. This has resulted in a deluge in demand for therapeutic services within the public mental health sector; second, mental health professionals describe their positioning and work as “a constant tug-of-war” where they are inundated and often overwhelmed with work, find themselves identifying with service users and taking on several roles simultaneously, and being challenged to find solutions often in dire and complex situations. They describe how creativity and flexibility are in demand in their day-to-day interactions and if they are to intervene in place of a health and welfare system that is faltering. Doing therapeutic work under such circumstances appears to be both emotionally onerous and stimulating with regard to conceptualising new ways of intervening in such complex psychosocial situations.

Research limitations/implications
The study is limited in that only mental health professionals presented their experiences and service users were not included. The findings do highlight how severe austerity policies impact mental health services and peoples’ lives.

Practical implications
The study has implications for policy regarding the provision and organisation of mental health services in contexts where crises and economic turmoil prevail.

Social implications
The results associate severe austerity with major changes in family and community life.

Originality/value
The paper provides insights and implications on how mental health services are impacted by socioeconomic conditions.
Exploring health care workers’ perceptions and experiences of communication with ethnic minority elders
Authors: Likupe Gloria , Baxter Carol , Jogi Mohamed 
Published: July 2018

Purpose
There is a recognition in Europe and in the western world of a demographic shift in the ageing population. While the overall ageing of the general population is growing, the numbers of immigrants getting old in their host countries is also increasing, thereby increasing the racial and ethnic proportion of older people in these countries. This changing landscape calls for understanding of issues related to health care provision, policy and research regarding ethnic minorities. Communication is seen as a key factor in understanding the needs of ethnic minority elders (EMEs). The purpose of this paper is to explore health care workers’ (HCWs) perceptions and experiences of communication with EMEs. In this paper the term HCW includes qualified nurses and health care assistants.

Design/methodology/approach
A descriptive qualitative study design using semi-structured interviews was employed. Ten HCWs, who had ethnic minorities in their care were individually interviewed to explore their perceptions and experiences of communication when caring for EMEs.

Findings
Analysis of data revealed that in common with all older people, EMEs experience stereotyped attitudes and difficulties in communication. However, EMEs face particular challenges, including cultural differences, different language and stereotyping of care based on misunderstood needs of EMEs. Facilitators of communication included appropriate training of HCWs and appropriate use of interpreters.

Research limitations/implications
Only homes willing to take part in the study gave permission for their staff to be interviewed. In addition, the HCWs came from various settings. Therefore, views of staff in homes who did not give permission may not be represented.

Practical implications
The diversity of older people needing care in nursing homes and the community calls for training in culturally competent communication for effective provision care provision for EMEs.

Originality/value
Training of health care staff in culturally appropriate communication requires effective practice.
The influence of cultural intelligence on intention of internet use
Authors: Coves Martínez Angel Luis , Sabiote-Ortiz Carmen M. , Rey-Pino Juan Miguel 
Published: July 2018

Purpose
Each culture is defined by norms, beliefs and values which influence and complicate individual thoughts and actions. Cultural intelligence (CQ) is a novel concept that reflects the ability of individuals of certain cultures to adapt to the general conditions of a different society. This study aims to explore the relationship between CQ and technology adoption in the form of intention to use the internet.

Design/methodology/approach
This quantitative empirical study, based on data from a questionnaire completed by 201 university students, proposes three models to analyse the direct, indirect and moderating influence of the CQ on intention to use the internet.

Findings
The study reveals that CQ has an indirect influence on the intention to use the internet.

Originality/value
Most research to date has focused on analysing the influence of CQ in the cross-cultural field. This work contributes to the development of the concept of CQ as a decisive factor in a globalised world and analyses its impact on the internet, a tool that is fundamental at all levels.
Can continuous improvement lead to satisfied customers? Evidence from the services industry
Authors: Koval Oksana , Nabareseh Stephen , Chromjakova Felicita , Marciniak Robert 
Published: July 2018

Purpose
To achieve higher customer satisfaction (CS), companies implement continuous improvement (CI) programs, regardless of the growing evidence of their failure to achieve declared goals. The purpose of this paper is twofold: first, to identify whether companies are able to improve CS through the application of CI; and, second, to identify what organizational practices are able to facilitate the impact of CI on CS.

Design/methodology/approach
To test the developed assumptions, the study uses the structural equation modeling technique. The data for analysis were collected from 304 service companies via a custom web-survey.

Findings
The research confirms the direct positive impact of CI on CS. Further, the study demonstrates that management commitment and rewards system that encourages employees to participate in CI play the major facilitating role in improving CS through CI. These practices accompanied by quality-oriented culture and employee training in the improvement tools provide necessary infrastructure to sustain CI in the companies over time. Additionally, regardless of the vital role of goal setting for CI established in previous research, the proposed study finds a limited ability of goal setting, as compared to other organizational practices, to facilitate CI–CS relationship.

Originality/value
The study contributes to the scarce field of research on CI implementation in the services environment. Further, the research assesses CS as a variable of interest, as opposite to the previous studies, considering CS as a part of the composite variable. The research assesses the impact of the training in CI methodology on the CI–CS relationship, while previous research focuses on the general, work-related training. The findings provide an important basis for further academic work in the area of quality management. The identified practices can serve as guidance for managers, implementing CI in their companies due to the high fit of the proposed model.
Disentangling the complexity of permafrost soil by using high resolution profiling of microbial community composition, key functions and respiration rates
Authors: Müller Oliver , Bang‐Andreasen Toke , White Richard Allen , Elberling Bo , Taş Neslihan , Kneafsey Timothy , Jansson Janet K. , Øvreås Lise 
Published: July 2018

SummaryThawing permafrost can stimulate microbial activity, leading to faster decomposition of formerly preserved organic matter and CO2 release. Detailed knowledge about the vertical distribution of the responsible microbial community that is changing with increasing soil depth is limited. In this study, we determined the microbial community composition from cores sampled in a high Arctic heath at Svalbard, Norway; spanning from the active layer (AL) into the permafrost layer (PL). A special aim has been on identifying a layer of recently thawed soil, the transition zone (TZ), which might provide new insights into the fate of thawing permafrost. A unique sampling strategy allowed us to observe a diverse and gradually shifting microbial community in the AL, a Bacteroidetes dominated community in the TZ and throughout the PL, a community strongly dominated by a single Actinobacteria family (Intrasporangiaceae). The contrasting abundances of these two taxa caused a community difference of about 60%, just within 3 cm from TZ to PL. We incubated subsamples at about 5°C and measured highest CO2 production rates under aerobic incubations, yet contrasting for five different layers and correlating to the microbial community composition. This high resolution strategy provides new insights on how microbial communities are structured in permafrost and a better understanding of how they respond to thaw.
