The cost of being stable: Trade-offs between effort and stability across a landscape of redundant motor solutions
Authors: Sohn M. Hongchul , Ting Lena H. 
Published: November 2018

AbstractCurrent musculoskeletal modeling approaches cannot account for variability in muscle activation patterns seen across individuals, who may differ in motor experience, motor training, or neurological health. While musculoskeletal simulations typically select muscle activation patterns that minimize muscular effort, and generate unstable limb dynamics, a few studies have shown that maximum-effort solutions can improve limb stability. Although humans and animals likely adopt solutions between these two extremes, we lack principled methods to explore how effort and stability shape how muscle activation patterns differ across individuals. Here we characterized trade-offs between muscular effort and limb stability in selecting muscle activation patterns for an isometric force generation task in a musculoskeletal model of the cat hindlimb. We define effort as the sum of squared activation across all muscles, and limb stability by the maximum real part of the eigenvalues of the linearized musculoskeletal system dynamics, with more negative values being more stable. Surprisingly, stability increased rapidly with only small increases in effort from the minimum-effort solution, suggesting that very small amounts of muscle coactivation are beneficial for postural stability. Further, effort beyond 40% of the maximum possible effort did not confer further increases in stability. We also found multiple muscle activation patterns with equivalent effort and stability, which could underlie variability observed across individuals with similar motor ability. Trade-off between muscle effort and limb stability could underlie diversity in muscle activation patterns observed across individuals, disease, learning, and rehabilitation.Author summaryCurrent computational musculoskeletal models select muscle activation patterns that minimize the amount of muscle activity used to generate a movement, creating unstable limb dynamics. However, experimentally, muscle activation patterns with various level of co-activation are observed for performing the same task both within and across individuals that likely help to stabilize the limb. Here we show that a trade-off between muscular effort and limb stability across the wide range of possible muscle activation patterns for a motor task could explain the diversity of muscle activation patterns seen across individuals, disease, learning and rehabilitation. Increased muscle activity is necessary to stabilize the limb, but could also limit the ability to learn new muscle activation pattern, potentially providing a mechanism to explain individual-specific muscle coordination patterns in health and disease. Finally, we provide a straightforward method for improving the physiological relevance of muscle activation pattern and musculoskeletal stability in simulations.

Published: November 2018

The Australian Synchrotron Imaging and Medical Beamline (IMBL) was designed to be the world's widest synchrotron X-ray beam, partly to enable clinical imaging and therapeutic applications for humans, as well as for imaging large-animal models. Our group is currently interested in imaging the airways of newly developed cystic fibrosis (CF) animal models that display human-like lung disease, such as the CF pig. One key outcome measure for assessing the effectiveness of CF airway therapies is the ability of the lung to clear inhaled particulates by mucociliary transit (MCT). This study extends the ex vivo sheep and pig tracheal-tissue studies previously performed by the authors at the IMBL. In the present study, attempts were made to determine whether the design of the IMBL is suitable for imaging tracheal MCT in live pigs. The movement of 200 µm-diameter high-refractive-index (HRI) glass-bead marker particles deposited onto the tracheal airway surface of eight live piglets was tracked and quantified and the MCT response to aerosol delivery was examined. A high-resolution computed tomographic (CT) whole-animal post-mortem scan of one pig was also performed to verify the large sample CT capabilities of the IMBL. MCT tracking particles were visible in all animals, and the automated MCT tracking algorithms used were able to identify and track many particles, but accuracy was reduced when particles moved faster than ∼6 mm min−1 (50 pixels between exposures), or when the particles touched or overlapped. Renderings were successfully made from the CT data set. Technical issues prevented use of reliable shuttering and hence radiation doses were variable. Since dose must be carefully controlled in future studies, estimates of the minimum achievable radiation doses using this experiment design are shown. In summary, this study demonstrated the suitability of the IMBL for large-animal tracheal MCT imaging, and for whole-animal CT.
Application of virtual flight test framework with derivative design optimization
Authors: Park Hyeong-Uk , Chung Joon , Kwon Ohyun 
Published: November 2018

Purpose
The purpose of this paper is a development of a virtual flight test framework with derivative design optimization. Aircraft manufactures and engineers have been putting significant effort into the design process to lower the cost of development and time to a minimum. In terms of flight tests and aircraft certification, implementing simulation and virtual test techniques may be a sufficient method in achieving these goals. In addition to simulation and virtual test, a derivative design can be implemented to satisfy different market demands and technical changes while reducing development cost and time.

Design/methodology/approach
In this paper, a derivative design optimization was applied to Expedition 350, a small piston engine powered aircraft developed by Found Aircraft in Canada. A derivative that changes the manned aircraft to an Unmanned Aerial Vehicle for payload delivery was considered. An optimum configuration was obtained while enhancing the endurance of the UAV. The multidisciplinary design optimization module of the framework represents the optimized configuration and additional parameters for the simulator. These values were implemented in the simulator and generated the aircraft model for simulation. Two aircraft models were generated for the flight test.

Findings
The optimization process delivered the UAV derivative of Expedition E350, and it had increased endurance up to 21.7 hours. The original and optimized models were implemented into virtual flight test. The cruise performance exhibited less than 10 per cent error on cruise performance between the original model and Pilots Operating Handbook (POH). The dynamic stability of original and optimized models was tested by checking Phugoid, short period, Dutch roll and spiral roll modes. Both models exhibited stable dynamic stability characteristics.

Practical implications
The original Expedition 350 was generated to verify the accuracy of the simulation data by comparing its result with actual flight test data. The optimized model was generated to evaluate the optimization results. Ultimately, the virtual flight test framework with an aircraft derivative design was proposed in this research. The additional module for derivative design optimization was developed and its results were implemented to commercial off-the-shelf simulators.

Originality/value
This paper proposed the application of UAV derivative design optimization for the virtual flight test framework. The methodology included the optimization of UAV derivative utilizing MDO and virtual flight testing of an optimized result with a flight simulator.

Authors: Chan Pui King 
Published: November 2018

Purpose
The purpose of this paper is to examine the significance of company record for journalist when investigating projects relating to conflict of interest that occurs in Hong Kong and in and connected with China.

Design/methodology/approach
The paper describes what company records are available, and how they are accessible for the public in Hong Kong. It then compares with the company record accessibility in China. The paper uses investigative projects done by the author and other journalists to illustrate how the records are significant. Some of the investigative projects that are related to China are used to illuminate the importance for the company record in Hong Kong for investigating issues in China.

Findings
Hong Kong maintains an efficient access to the company record that benefits the journalists for probing into the issues of conflict of interest. This efficient system has faced threats when the government proposed to withdraw some of the important records from the general public access.

Originality/value
This paper will be of interest to journalists and journalism students and scholars who are interested to know the practical uses of company records. Policymakers will also learn from this paper that a restriction in the public access to the company record will make a huge impact to the justice-seeking journalist work.

Authors: Patel Hiral , Hanumappa Anilkumar 
Published: November 2018

PurposeThe purpose of this paper is to identify various legal issues that affect libraries in India.Design/methodology/approachThe method adopted in this study was to identify and analyze all cases filed in the Indian Supreme Court, High Courts and Tribunals and Commissions and reported in the Westlaw India database for the 10-year period from 2008 to 2017.FindingsAmong the identified cases that were related to libraries or library professionals, a large majority of them were issues related to service or employment such as pay scales, promotion, age of superannuation and service termination. There were very few cases related to library work, such as library access, services provided and copyright.Research limitations/implicationsThe current study is based on study of cases that have been reported and mentioned in Westlaw India Legal Database and occurring during the limited period from 2008 to 2017. The implications of the study are manifold, with the main implication being the urgent need to introduce basic legal education and training to library professionals. The other implication is the need to further research in this domain due to lack of sufficient studies on the topic and enrich the library and information science (LIS) literature.Originality/valueThis study would not only help create awareness about legal issues related to libraries and library professionals but also help in understanding the main areas of litigation involving libraries and library professionals. The study also makes a case for introduction of basic legal education for LIS professionals. The paper adopts a novel research approach that can be replicated by researchers in other countries to enable international comparisons.
Semantic matching of job seeker to vacancy: a bidirectional approach
Authors: Chala Sisay Adugna , Ansari Fazel , Fathi Madjid , Tijdens Kea 
Published: November 2018

Purpose
The purpose of this paper is to propose a framework of an automatic bidirectional matching system that measures the degree of semantic similarity of job-seeker qualifications and skills, against the vacancy provided by employers or job-agents.

Design/methodology/approach
The paper presents a framework of bidirectional jobseeker-to-vacancy matching system. Using occupational data from various sources such as the WageIndicator web survey, International Standard Classification of Occupations, European Skills, Competences, Qualifications, and Occupations as well as vacancy data from various open access internet sources and job seekers information from social networking sites, the authors apply machine learning techniques for bidirectional matching of job vacancies and occupational standards to enhance the contents of job vacancies and job seekers profiles. The authors also apply bidirectional matching of job seeker profiles and vacancies, i.e., semantic matching vacancies to job seekers and vice versa in the individual level. Moreover, data from occupational standards and social networks were utilized to enhance the relevance (i.e. degree of similarity) of job vacancies and job seekers, respectively.

Findings
The paper provides empirical insights of increase in job vacancy advertisements on the selected jobs – Internet of Things – with respect to other job vacancies, and identifies the evolution of job profiles and its effect on job vacancies announcements in the era of Industry 4.0. In addition, the paper shows the gap between job seeker interests and available jobs in the selected job area.

Research limitations/implications
Due to limited data about jobseekers, the research results may not guarantee high quality of recommendation and maturity of matching results. Therefore, further research is required to test if the proposed system works for other domains as well as more diverse data sets.

Originality/value
The paper demonstrates how online jobseeker-to-vacancy matching can be improved by use of semantic technology and the integration of occupational standards, web survey data, and social networking data into user profile collection and matching.
Local horizontal network membership for accelerated global market reach
Authors: Ryan Paul , Evers Natasha , Smith Adele , Andersson Svante 
Published: November 2018

PurposeThe purpose of this paper is to explain how some born global firms can leverage the rich social capital in their local (home country) horizontal network for accelerated international market entry and growth. Horizontal networks warrant separate attention from their vertical counterparts, which, along with those focussed on external international contexts, dominate most network studies in the realm of born global research.Design/methodology/approachThe study utilises a multi-level qualitative approach in the study of a multi-firm population of animators in Ireland that, due to the small domestic market for their product, needed to pursue global customers from inception. The case study domain was purposely selected as a critical exemplar of a local horizontal network operating in a highly globalised industry. The authors collected data through in-depth interviews with 16 company founders. This primary interview data were complemented by interviews with staff at the apposite industry association and triangulated with secondary data on the local and global industry conditions, members’ international successes and awards.FindingsThe results demonstrate how active membership of a local horizontal network can be leveraged for the acquisition of international market knowledge and customers for born global ventures. This arises from the sharing of collective market knowledge and communal global customer information within the network to mutual benefit.Originality/valueAlthough limited by the specific conditions in this highly globalised, non-competitive industry context, this study is unique in that it finds that cooperative interpersonal and inter-firm relationships embedded in a local horizontal social network, and mediated in part by an institutional support actor, emerge as important levers for a born global’s accelerated acquisition of foreign market knowledge and of global customers.
Good news, bad news, and fake news
Authors: Buschman John 
Published: November 2018

PurposeLibrary and Information Science (LIS) has seen an explosion of responses to fake news in the aftermath of the 2016 US election, political in nature, eschewing “neutrality” supporting democracy. The purpose of this paper is to trace the definition of fake news, the challenges, the roots of recent respondes to fake news, notes that the theoretical understanding of democracy must keep pace with these efforts.Design/methodology/approachConceptual analysis of the LIS literature concerning fake news and its underlying themes; unpacking of actually existing democracy, re-linked to LIS practices.FindingsDemocracy does not require a space cleared of distorting claims but spaces suited to grappling with them, a call to address fake news, and not simply a matter of clearing up information sources; librarians should prepared to engage at the next level. Libraries stand for the proposition that there is more-true information which is worth accessing, organizing, etc., and for inclusion. Whether explicitly political or not, the imaginative uses to which libraries are put do enrich civil society and the public sphere. Libraries help to counter fake news both through specific educative actions aimed at it and as broadly educative institutions with a coherent notion of their relationship to informational discernment in democracy.Originality/valueLIS discourse on fake news has value, and references democracy, but assumes a set of traditional relationships between informing, libraries and democracy. This paper goes at both the lesser role of informing and highlights the (arguably) greater social role of libraries in democratic society.
Scheduling stored combat load retrieval
Authors: Smith William 
Published: November 2018

Purpose
This paper aims to raise awareness of a potential planning pitfall and provide recommendations on how to assess and improve upon current practices. In potential conflict areas, such as the Korean Theater of Operations (KTO), military forces are required to store a portion of their ammunition combat load within depots and ammunition supply points under the control of a servicing ammunition company. This necessitates a lengthy retrieval process, as the ammunition company does not have enough resources to serve all customers simultaneously.

Design/methodology/approach
The stored combat load (SCL) retrieval process is modeled as a parallel machine scheduling problem and simulated using synthetic requirements. The current system of retrieval is contrasted against a proposed alternate system through a series of simulations scaled across three factors: number of ammunition company Soldiers, number of customer units and number of magazines.

Findings
The proposed alternate system demonstrates a significant potential for reducing the makespan of the SCL retrieval process when more than half of the magazines store SCL for multiple customers and there are more than five customers per Soldier.

Originality/value
Transitioning military units from a peacetime standing to full combat readiness as quickly as possible is of immense value within the KTO and other hostile areas with established troops not actively engaged in combat.
Halal certification compliance and its effects on companies’ innovative and market performance
Authors: Salindal Normia Akmad 
Published: November 2018

Purpose
The purpose of this study is to identify the effect of halal certification on innovative and market business performance of halal-certified food companies in the Philippines. Through this empirical study, halal-registered and about-to-register companies would have a wider perspective and a realistic view on what to expect from halal certification. The study also hopes to enrich halal certification literature and contribute further to the better understanding of the relationship between halal certification and the business performance.

Design/methodology/approach
This empirical study primarily uses a quantitative approach in analyzing the relationship between halal certification and the business performance in terms of innovative and market performance. The primary data are gathered through a survey involving 211 food companies (141 halal-certified and 70 non-halal-certified). The results are analyzed using confirmatory factor analysis, structural equation modeling and independent sample t-test.

Findings
First, the analysis highlights that halal certification significantly affects innovative performance of halal-certified food companies. Second, the improvements in innovative performance lead to market performance improvements. Third, innovative performance fully mediates the relationship between halal certification and market performance. Finally, halal-certified food companies and non-halal-certified food companies have significant difference in terms of innovative performance and market performance.

Research limitations/implications
First, the population of this study consisted of only food companies in the Philippines listed in the Bureau of Product and Standard. Second, only the respective quality management representatives of the responding companies were the main respondent. Third, the samples used are from Philippines only. Therefore, the ability to generalize the reported results to all types of industry is restricted. To generalize the results of this study, additional research is desired to test the suggested model in various countries where Muslims are minority.

Practical implications
Understanding the impact of halal certification and its business value through empirical study should provide “about to be registered organizations” a wider perspective and a realistic view on what to expect after halal certification. It will provide factual evidences that may aid halal-certified companies in decision-making with respect to halal certification and whether it complicates or compliments their organizations’ business.

Originality/value
To the best of the author’s knowledge, no research has yet been conducted to investigate the impact of halal certification on business performance in the Philippines. This study, therefore, fills the gap in the research area. Through this empirical study, halal-registered and about-to-register organizations would have a wider perspective and a realistic view on what to expect from halal certification.
