Authors: Xu Yangjie , He Dong , Wang Qiang , Guo Hongyang , Li Qing , Xie Zongliang , Huang Yongmei
Published: August 2019

In this paper, an improved method of measuring wavefront aberration based on image with machine learning is proposed. This method had better real-time performance and higher estimation accuracy in free space optical communication in cases of strong atmospheric turbulence. We demonstrated that the network we optimized could use the point spread functions (PSFs) at a defocused plane to calculate the corresponding Zernike coefficients accurately. The computation time of the network was about 6–7 ms and the root-mean-square (RMS) wavefront error (WFE) between reconstruction and input was, on average, within 0.1263 waves in the situation of D/r0 = 20 in simulation, where D was the telescope diameter and r0 was the atmospheric coherent length. Adequate simulations and experiments were carried out to indicate the effectiveness and accuracy of the proposed method.

Authors: Li Bin , Cheng Tonglei , Chen Junxin , Yan Xin
Published: August 2019

A surface plasmon resonance (SPR) liquid refractive index sensor based on photonic crystal fiber (PCF) is proposed. The PCF is made of the exposed core structure, and the gold film is formed by electron beam evaporation within its defects. The sensitivity of the sensor is improved by coating graphene on the surface of the gold film. The experimental results show that the sensitivity of the sensor is increased by 390 nm/RIU after the introduction of graphene, and finally to 2290 nm/RIU. The experiment and simulation have a good consistency. Significantly, the sensor can be reused, and the measurement accuracy can be maintained.

Authors: Yin Yunfei , Guan Liufa , Zheng Chengen
Published: August 2019

For the research and development of sensor systems, the collection and fusion of sensing data is the core. In order to make sensor data acquisition change with the change in environment, a dynamic data acquisition and fusion method based on feedback control is proposed in this paper. According to the sensing data acquisition and fusion model, the optimal acquisition of sensor data is achieved through real-time dynamic judgment of the collected data, decision-making of the next acquisition time interval, and adjustment. This model enables the sensor system to adapt to different environments. An experimental study of the proposed model was carried out on an experimental platform, and the results show that the proposed model can not only reflect the change in sensing data but also improve the transmission efficiency.

Published: August 2019

Waveguide-based photonic sensors provide a unique combination of high sensitivity, compact size and label-free, multiplexed operation. Interferometric configurations furthermore enable a simple, fixed-wavelength read-out making them particularly suitable for low-cost diagnostic and monitoring devices. Their limit of detection, i.e., the lowest analyte concentration that can be reliably observed, mainly depends on the sensors response to small refractive index changes, and the noise in the read-out system. While enhancements in the sensors response have been extensively studied, noise optimization has received much less attention. Here we show that order-of-magnitude enhancements in the limit of detection can be achieved through systematic noise reduction, and demonstrate a limit of detection of ∼ 10 − 8 RIU with a silicon nitride sensor operating at telecom wavelengths.
A Barcoded Polymer-Based Cross-Reactive Spectroscopic Sensor Array for Organic Volatiles
Authors: Fitzgerald Jessica E. , Shen Jianliang , Fenniri Hicham
Published: August 2019

The development of cross-reactive sensor arrays for volatile organics (electronic noses, e-noses) is an active area of research. In this manuscript, we present a new format for barcoded polymer sensor arrays based on porous polymer beads. An array of nine self-encoded polymers was analyzed by Raman spectroscopy before and after exposure to a series of volatile organic compounds, and the changes in the vibrational fingerprints of their polymers was recorded before and after exposure. Our results show that the spectroscopic changes experienced by the porous spectroscopically encoded beads after exposure to an analyte can be used to identify and classify the target analytes. To expedite this analysis, analyte-specific changes induced in the sensor arrays were transformed into a response pattern using multivariate data analysis. These studies established the barcoded bead array format as a potentially effective sensing element in e-nose devices. Devices such as these have the potential to advance personalized medicine, providing a platform for non-invasive, real-time volatile metabolite detection.
Reliable Indoor Pseudolite Positioning Based on a Robust Estimation and Partial Ambiguity Resolution Method
Authors: Li Xin , Huang Guanwen , Zhang Peng , Zhang Qin
Published: August 2019

The unscented Kalman filter (UKF) can effectively reduce the linearized model error and the dependence on initial coordinate values for indoor pseudolite (PL) positioning unlike the extended Kalman filter (EKF). However, PL observations are prone to various abnormalities because the indoor environment is usually complex. Standard UKF (SUKF) lacks resistance to frequent abnormal observations. This inadequacy brings difficulty in guaranteeing the accuracy and reliability of indoor PL positioning, especially for phase-based high-precision positioning. In this type of positioning, the ambiguity resolution (AR) will be difficult to achieve in the presence of abnormal observations. In this study, a robust UKF (RUKF) and partial AR (PAR) algorithm are introduced and applied in indoor PL positioning. First, the UKF is used for parameter estimation. Then, the anomaly recognition statistics and optimal ambiguity subset of PAR are constructed on the basis of the posterior residuals. The IGGIII scheme is adopted to weaken the influence of abnormal observation, and the PAR strategy is conducted in case of failure of the conventional PL-AR. The superiority of our proposed algorithm is validated using the measured indoor PL data for code-based differential PL (DPL) and phase-based real-time kinematic (RTK) positioning modes. Numerical results indicate that the positioning accuracy of RUKF-based indoor DPL is higher with a decimeter-level improvement compared that of the SUKF, especially in the presence of large gross errors. In terms of high-precision RTK positioning, RUKF can correctly identify centimeter-level anomalous observations and obtain a corresponding positioning accuracy improvement compared with the SUKF. When relatively large gross errors exist, the conventional method cannot easily realize PL-AR. By contrast, the combination of RUKF and the PAR algorithm can achieve PL-AR for the selected ambiguity subset successfully and can improve the positioning accuracy and reliability significantly. In summary, our proposed algorithm has certain resistance ability for abnormal observations. The indoor PL positioning of this algorithm outperforms that of the conventional method. Thus, the algorithm has some practical application value, especially for kinematic positioning.

Published: August 2019

Current medical facilities usually lead to a very high cost especially for developing countries, rural areas and mass casualty incidents. Therefore, advanced electronic health systems are gaining momentum. In this paper, we first compared our novel off the shelf experimental wired Body Sensor Networks (BSN), that is, Digital First Aid (DigiAID) with the existing commercial product called as Hexoskin. We showed the viability of DigiAID through extensive real measurements during daily activities by both male and females. It was found that the major hurdle was wires to be worn by the subjects. Accordingly, we proposed and characterized the wireless DigiAID platform for wireless BSN (WBSN). Understanding the effect of body movements on wireless data transmission in WBSN is also of major importance. Therefore, this paper comprehensively evaluates and analyzes the impact of body movements, (a) to ensure transmission of data at different radio power levels and (b) its impact on the topology of the WBSN. Based on this we have proposed a dynamic power control algorithm that adapts the transmitting power according to the packet reception in an energy efficient manner. The results show that we have achieved substantial power savings at various nodes attached to the human body.
Development of Open-Tubular-Type Micro Gas Chromatography Column with Bump Structures
Authors: Lee Janghyeon , Lim Si-Hyung
Published: August 2019

Gas chromatography (GC) is the chemical analysis technique most widely used to separate and identify gas components, and it has been extensively applied in various gas analysis fields such as non-invasive medical diagnoses, indoor air quality monitoring, and outdoor environmental monitoring. Micro-electro-mechanical systems (MEMS)-based GC columns are essential for miniaturizing an integrated gas analysis system (Micro GC system). This study reports an open-tubular-type micro GC (μ-GC) column with internal bump structures (bump structure μ-GC column) that substantially increase the interaction between the gas mixture and a stationary phase. The developed bump structure μ-GC column, which was fabricated on a 2 cm × 2 cm μ-GC chip and coated with a non-polar stationary phase, is 1.5 m-long, 150 μm-wide, and 400 μm-deep. It has an internal microfluidic channel in which the bumps, which are 150 μm diameter half-circles, are alternatingly disposed to face each other on the surface of the microchannel. The fabricated bump structure μ-GC column yielded a height-equivalent-to-a-theoretical-plate (HETP) of 0.009 cm (11,110 plates/m) at an optimal carrier gas velocity of 17 cm/s. The mechanically robust bump structure μ-GC column proposed in this study achieved higher separation efficiency than a commercially available GC column and a typical μ-GC column with internal post structures classified as a semi-packed-type column. The experimental results demonstrate that the developed bump structure μ-GC column can separate a gas mixture completely, with excellent separation resolution for formaldehyde, benzene, toluene, ethylbenzene, and xylene mixture, under programmed operating temperatures.
Neuro-Advancements and the Role of Nurses as Stated in Academic Literature and Canadian Newspapers
Authors: Deloria Rochelle , Wolbring Gregor
Published: August 2019

Neurosciences and neurotechnologies (from now on called neuro-advancements) constantly evolve and influence all facets of society. Neuroethics and neuro-governance discourses focus on the impact of neuro-advancements on individuals and society, and stakeholder involvement is identified as an important aspect of being able to deal with such an impact. Nurses engage with neuro-advancements within their occupation, including neuro-linked assistive technologies, such as brain-computer interfaces, cochlear implants, and virtual reality. The role of nurses is multifaceted and includes being providers of clinical and other health services, educators, advocates for their field and their clients, including disabled people, researchers, and influencers of policy discourses. Nurses have a stake in how neuro-advancements are governed, therefore, being influencers of neuroethics and neuro-governance discourses should be one of these roles. Lifelong learning and professional development could be one mechanism to increase the knowledge of nurses about ethical, social, and legal issues linked to neuro-advancements, which in turn, would allow nurses to provide meaningful input towards neuro-advancement discussions. Disabled people are often the recipients of neuro-advancements and are clients of nurses, therefore, they have a stake in the way nurses interact with neuro-advancements and influence the sociotechnical context of neuro-advancements, which include neuro-linked assistive devices. We performed a scoping review to investigate the role of narrative around nurses in relation to neuro-advancements within academic literature and newspapers. We found minimal engagement with the role of nurses outside of clinical services. No article raised the issue of nurses having to be involved in neuro-ethics and neuro-governance discussions or how lifelong learning could be used to gain that competency. Few articles used the term assistive technology or assistive device and no article covered the engagement of nurses with disabled people within a socio-technical context. We submit that the role narrative falls short of what is expected from nurses and shows shortcomings at the intersection of nurses, socio-technical approaches to neuro-assistive technologies and other neuro-advancements and people with disabilities. Neuro-governance and neuroethic discourses could be a useful way for nurses and disabled people to co-shape the socio-technical context of neuro-advancements, including neuro-assistive technologies. Lifelong learning initiatives should be put in place to provide the knowledge necessary for nurses to take part in the neuroethics and neuro-governance discussion.
The Sonic Intra-Face of a Noisy Feminist Social Kitchen
Authors: España Keller Juliana
Published: August 2019

This paper asks what is the value of transforming the kitchen into a sonic performative work and public site for art and social practice. A Public Kitchen is formed by recreating the private and domestic space of a kitchen into a public space through a sonic performance artwork. The kitchen table is a platform for exploring, repositioning and amplifying kitchen tools as material phenomena through electronic and manual manipulation into an immersive sonic performance installation. This platform becomes a collaborative social space, where somatic movement and sensory, sonic power of the repositioned kitchen tools are built on a relational architecture of iterative sound performances that position the art historical and the sociopolitical, transforming disciplinary interpretations of the body and technology as something that is not specifically exclusively human but post-human. A Public Kitchen represents a pedagogical strategy for organizing and responding collectively to the local, operating as an independent nomadic event that speaks through a creative practice that is an unfolding process. (Re)imagining the social in a Public Kitchen produces noisy affects in a sonic intra-face that can contribute to transforming our social imaginations, forming daring dissonant narratives that feed post-human ethical practices and feminist genealogies. This paper reveals what matters—a feminist struggle invaluable in channeling the intra-personal; through the entanglement of the self, where language, meaning and subjectivity are relational to human difference and to what is felt from the social, what informs from a multi-cultural nomadic existence and diffractive perspective. The labored body is entangled with post-human contingencies of food preparation, family and social history, ritual, tradition, social geography, local politics, and women’s oppression; and is resonant and communicates as a site where new sonic techniques of existence are created and experiences shared.
Is Anyone Listening? Audience Engagement through Public Media Related to the Scottish Independence Referendum
Authors: Agirreazkuenaga-Onaindia Irati , Larrondo-Ureta Ainara , Peña-Fernández Simón
Published: August 2019

This paper explores perspectives from which citizen participation in media debates on civic issues can be reconsidered by means of a review of the existing literature on this subject and a qualitative study of how one particular public service media programme facilitated audience engagement and involvement in public discussion leading up to a major political event. The first section provides a general discussion of what media organisations do to engage the public they serve on political and social issues, the challenge of stimulating audience involvement and the ways in which editors and producers attempt to give average citizens a voice on topics normally framed by elites. The second offers a case study based on semi-structured interviews and content analysis of public participation in Morning Call, a weekday British Broadcasting Corporation (BBC) Radio Scotland phone-in news and current affairs show (the only programme of its type broadcast in Scotland) during the run-up to the 2014 Scottish independence referendum. Focus has been placed on determining what programmes of this nature can and cannot achieve in terms of civic engagement and which practices implemented by public broadcasting networks best stimulate audience engagement.
Residence Time Effects on Molybdenum Adsorption on Soils: Elucidation by Multi-Reaction Modeling and XANES Analysis
Authors: Sun Wenguang , Roy Amitava , Selim H. Magdi
Published: August 2019

To investigate the influence of residence time on molybdenum [Mo(VI)] adsorption behavior in soil environments, kinetic batch experiments coupled with X-ray near-edge structure (XANES) spectroscopy were performed for a neutral-pH soil (Webster loam) and two acidic soils (Mahan sand and Windsor sand) at different time scales (1 day–1 year). Batch-type experiments indicated that retention of Mo(VI) was rate limited and typical biphasic for soils. Initial rapid retention was followed by a continued slow retention with increasing aging time for Mahan and Windsor soils. In contrast, the reaction for Webster soil was nearly complete after 8 h, reflecting difference in soil properties. XANES analysis for Webster soil confirmed that most of Mo was bound to montmorillonite during long-term reaction time, whereas kaolinite constitutes a very important host phase for Mahan and Windsor soils. Sequential extraction results indicated that the percentages of Fe/Al oxide and residual fractions increased at the advanced time periods for Mahan and Windsor soils. The goodness-of-fit of numerical modeling results indicated that a simple version of multi-reaction model (MRM) with equilibrium and kinetic sorption sites was capable of describing Mo(VI) retention data for Webster loam. However, for Windsor and Mahan soils, an additional irreversible sorption site was required to simulate Mo(VI) retention over time. Although each site from MRM model cannot be unequivocally clarified from each other by either XANES analysis or sequential extraction results, their finding provided evidence of surface irreversible reactions at long residence times.
Smart Urban Planning: Evaluating Urban Logistics Performance of Innovative Solutions and Sustainable Policies in the Venice Lagoon—the Results of a Case Study
Authors: Mazzarino Marco , Rubini Lucio
Published: August 2019

Currently, remarkable gaps of operational, social and environmental efficiency and overall sub-optimization of the logistics and mobility systems exist in urban areas. There is then the need to promote and assess innovative transport solutions and policy-making within SUMPs (Sustainable Urban Mobility Plans) to deal with such critical issues in order to improve urban sustainability. The paper focuses on the case study of the Venice Lagoon, where islands—despite representing a relevant feature of urban planning—face a tremendous lack of accessibility, depopulation, social cohesion and they turn out to be poorly connected. By developing an original scenario-building methodological framework and performing data collection activities, the purpose of the paper consists of assessing the feasibility of a mixed passenger and freight transport system —sometimes called cargo hitching. Mixed passenger and freight systems/cargo hitching are considered as an innovative framework based on the integration of freight and passenger urban systems and resources to optimize the existing transport capacity, and thus, urban sustainability. Results show that the overall existing urban transport capacity can accommodate urban freight flows on main connections in the Lagoon. The reduction in spare public transport capacity, as well as in the number (and type) of circulating freight boats show—in various scenarios—the degree of optimization of the resulting urban network configuration and the positive impacts on urban sustainability. This paves the way for the regulatory framework to adopt proposed solutions.
Project Portfolio Selection Considering Total Cost of Ownership in the Automobile Industry
Authors: Lee Seunghoon , Lee Young , Choi Yongho
Published: August 2019

Project portfolio selection for developing a new product is critical to a company because the attributes of the project reflect on the price, quality, and functionality of the developed product. The market evaluates the developed product and the assessment of the product value determines its sale on the market. The project portfolio selection and sales are interconnected from a corporate perspective. The automobile industry is an industry which responds to the issue of business sustainability sensitively because their business directly relates to the environment. In this study, business sustainability was approached through the perspective of total cost of ownership (TCO) embedded into the project selection model after the attributes of the project, investment and efficiency, and the TCO of the product were combined to generate a sales function. The sales and revenue models were proposed, and the validity of the models was confirmed using a case from the automobile industry. As a result of the experiments, the sales model tended to show that the market share increased by selecting the proper number of projects to maximize sales. In contrast, the revenue model showed a tendency to select projects more than the sales model in order to maximize the profits of the company. By suggesting project selection models in a new perspective different from the ones in existing studies, this study is valuable with regard to the fact that the suggested models preserve project interrelationships, TCO, and product sales in a practical manner to enhance business sustainability.
Development of a Sustainability Index for an Energy Management System in Thailand
Authors: Nakthong Vichan , Kubaha Kuskana
Published: August 2019

The ISO 50001 energy management system (EnMS) standard was published in June 2011 and has been widely adopted by organizations from around the world, including Thailand. From 2014–2017, there was a continuous increase in the number of ISO 50001-certified companies in the East Asia and Pacific regions and, more broadly, the world, although this is not consistent with the number of companies that emerged during this period in Thailand. This information shows that the implementation of energy management in some companies may not be sustainable. This research offers a novel method for assessing the quality of energy management in the form of an energy management system sustainability index (EnMS SI) framework, presenting the economic, organizational, energy performance, and environmental aspects of sustainable energy management. Data collection, from a literature review of related research and the EnMS good practices, was implemented in order to select sustainability indicators and further develop a sustainability index for energy management. The analytic hierarchy process (AHP) and weighted arithmetic mean (WAM) were used to establish an EnMS SI. The study results were then assessed and validated using 31 ISO 50001-certified companies in Thailand. Direct interviews and questionnaires were used to obtain responses from energy management representatives. The studied data indicated that an EnMS SI framework can be used in qualitative analyses to effectively determine the sustainability of an EnMS. Significant sustainability indicators, consisting of continuous benefits, top management commitment, and long-term strategic planning, were found. The results also revealed that the EnMS in Thailand has been significantly economically weak. The EnMS SI framework is a tool for assessing energy management sustainability, which allows for the determination of an organization’s actual strengths and weaknesses. The benefits of this framework include the possibility of determining guidelines for correcting and improving the EnMS to achieve sustainability.
Identifying Business Practices Promoting Sustainability in Aboriginal Tourism Enterprises in Remote Australia
Authors: Akbar Skye , Hallak Rob
Published: August 2019

Aboriginal tourism entrepreneurs operating in remote regions of Australia draw on their 60,000 years of heritage to offer unique and distinct cultural experiences to domestic and international tourists. Living and operating in remote climates presents challenges to achieving successful and sustainable enterprises, including extreme weather, substandard infrastructure, distance from policy makers, distance from markets and the commercialisation of culture, which is customarily owned by and for use by traditional custodians, to produce and deliver a market-ready tourism product. However, many remote Aboriginal tourism entrepreneurs nevertheless achieve success and sustainability. This paper builds on the work of Foley to identify the characteristics of successful remote Aboriginal tourism enterprises and Aboriginal entrepreneurs in remote areas and the resourceful and creative business practices used by remote Aboriginal entrepreneurs to overcome barriers to success and finds that ongoing connections to community and culture are a key factor in that success. It also draws on the United Nation’s Sustainable Development Goals to identify how the characteristics of remote tourism entrepreneurs and enterprises promote or inhibit the achievement of sustainability and suggests that they offer a framework for effective support of remote Aboriginal entrepreneurs. It concludes by noting that the industry would benefit from further investigation of the contributions made to sustainability by remote Aboriginal tourism enterprises and their stakeholders.
Spatial Heterogeneity of the Carbon Emission Effect Resulting from Urban Expansion among Three Coastal Agglomerations in China

Published: August 2019

Land-use change, particularly urban expansion, can greatly affect the carbon balance, both from the aspects of terrestrial ecosystems and anthropogenic carbon emissions. Coastal China is a typical region of rapid urban expansion, and obvious spatial heterogeneity exists from the north to south. However, the different urban change characteristics and the effect on carbon balance remain undetermined. By unifying the spatial-temporal resolution of carbon source and sink data, we effectively compared the carbon budgets of three coastal urban agglomerations in China. The results show that all of the three urban agglomerations have undergone an obvious urban expansion process, with the built-up area increasing from 1.03 × 104 km2 in 2000 to 3.06 × 104 km2 in 2013. For Beijing–Tianjin–Hebei (BTH), the built-up area gradually expanded. The built-up area in the Yangtze River Delta (YRD) gradually changed before 2007 but rapidly grew thereafter. The built-up expansion of the Pearl River Delta (PRD) passed through three growing stages and showed the largest mean patch size. Carbon emission spatial patterns in the three urban agglomerations are consistent with their economic development, from which the net ecosystem production (NEP) spatial patterns are very different. Compared to carbon emissions, NEP has a carbon sink effect and can absorb some carbon emissions, but the amounts were all much lower than the carbon emissions in the three urban agglomerations. The carbon sink effect in the Yangtze River Delta is the most obvious, with the Pearl River Delta following, and the lowest effect is in Beijing–Tianjin–Hebei. Finally, a scientific basis for policy-making is provided for viable CO2 emission mitigation policies.
Sustainable Urban Mobility Plans: How Do They Work?
Authors: Kiba-Janiak Maja , Witkowski Jarosław
Published: August 2019

The growing demand for passenger and freight transport in cities, resulting from the population growth in urbanized areas, has led to increasing problems with congestion, environmental pollution and, as a consequence, to a decrease in quality of life. This problem was noticed by the European Commission, which began to promote the concept of sustainable urban mobility plans (SUMPs). The efficient implementation of SUMPs requires tools for its evaluation. However, in the literature, most proposed assessment tools relate mainly to passenger transport, omitting the freight transport. The purpose of this paper is to utilize a multiple criteria analysis with the use of the Promethee method in order to assess the level of advancement of selected European Union (EU) capital cities in the field of sustainable urban mobility plan formulation and implementation. This method has been applied on the basis of a survey conducted among representatives of 15 EU capital cities and analyses of transportation plans. This research shows that cities that have a comprehensive transport plan consistently collaborate with different stakeholder groups, have implemented the greatest number of measures in the field of sustainable urban transport, and have achieved the best results in terms of safety and NO2 (nitrogen oxides) and PM (particulate matter) emissions.
Strategies of Forestry Carbon Sink under Forest Insurance and Subsidies
Authors: Song Ye , Peng Hongjun
Published: August 2019

We take the forest insurance supply chain, composed of a forestry enterprise and an insurance company, as the research object. The forestry carbon sink, operated by the forestry enterprise, is the subject matter of insurance. The Stackelberg game model is constructed to study the optimal strategies of the forestry enterprise and insurance company under the forest insurance mechanism, as well as the impact of government subsidies, probability of deforestation, and carbon limit level on the decision-making and profit of the forestry enterprise and insurance company. The results show that the larger the carbon limit, the looser carbon restraint policy, which causes the forestry enterprise to reduce the scale of carbon sink forest, and the insurance company lowers the premium level. As the probability of deforestation increases, both the scale of the carbon sink forest and the premium level will decrease. Direct subsidies for the premiums of the forestry enterprise are conducive to expanding the scale of carbon sink forest, but will lead to the insurance company improving the premium level. Providing indirect subsidies to the insurance company’s operating costs will not only expand the scale of the carbon sink forest, but also lower the premium level. In the case of the same number of premium subsidies, indirect subsidies are more effective than direct subsidies in increasing the forestry enterprise’s income and promoting it to expand the forest scale.
Evaluating the Vulnerability of Time-Sensitive Transportation Networks: A Hub Center Interdiction Problem
Authors: Lei Ting L.
Published: August 2019

Time-sensitive transportation systems have received increasing research attention recently. Examples of time-sensitive networks include those of perishable goods, high-value commodity, and express delivery. Much research has been devoted to optimally locating key facilities such as transportation hubs to minimize transit time. However, there is a lack of research attention to the reliability and vulnerability of time-sensitive transportation networks. Such issues cannot be ignored as facilities can be lost due to reasons such as extreme weather, equipment malfunction, and even intentional attacks. This paper proposes a hub interdiction center (HIC) model for evaluating the vulnerability of time-sensitive hub-and-spoke networks under disruptions. The model identifies the set of hub facilities whose loss will lead to the greatest increase in the worst-case transit time. From a planning perspective, such hubs are critical facilities that should be protected or enhanced by preventive measures. An efficient integer linear programming (ILP) formulation of the new model is developed. Computational experiments on a widely used US air passenger dataset show that losing a small number of hub facilities can double the maximum transit time.
Moderating Effects of the Timing of Reward Determination and Performance Standards between Rewards and Self-Efficacy for Sustainable Intrinsic Motivation
Authors: Park Joowoong , Yang Jae-Suk
Published: August 2019

The purpose of this study is to determine the moderating effects of the timing of reward determination and performance standards on the relationship between pay-for-performance and self-efficacy. It is an experimental study; the sample included 352 participants from Amazon Mechanical Turk, and an online experiment was conducted on an external website. The model was tested for mediation and moderation processes using regression analysis and analysis of variance (ANOVA). The results showed a mediating effect of self-efficacy between pay-for-performance and intrinsic motivation. A moderating effect of performance standards (absolute, relative, ambiguous) on the relationship between pay-for-performance and self-efficacy was also found. Moreover, performance standards were found to be more important moderators than the timing of reward determination. The theoretical contribution of this paper was to observe the concept of timing of reward determination and empirically validate self-determination theory. The results also infer that people measure their own efficacy or competence by comparing themselves with others more than with other performance standards. The use of absolute performance standards is recommended for sustainable self-efficacy and intrinsic motivation of employees. This study introduced the concept of the timing of reward determination (i.e., before or after completion of a performance-related task) and verified the moderating effect of performance standards.

Authors: Yun Hee Jeong , Kang Dong Jin , Kim Dong-Kap , Kang Youngeun
Published: August 2019

The aim of this study was to determine the characteristics of forest wetlands by developing factors for site suitability and applying these factors to 107 sites in South Korea. We developed a forest wetland assessment in a Geographic Information Systems (GIS) environment to assess site suitability. We considered 16 factors including slope, elevation, visibility, land ownership, distance to city, and so on. We conducted an expert survey with experts to analyze the relative importance by using the Analytic Hierarchy Process (AHP). We found that the order of importance of the 5 criteria applied in this study was: (1) Natural Ecology, (2) Land Use, (3) Natural Landscape, (4) Tourist Attraction, and (5) Accessibility. We then analyzed the spatial characteristics of each site based on the AHP result and divided the 107 forest wetlands into three categories by cluster analysis. Sites with high scores on the assessment were primarily the landscape ecology or land use criterion. Our differentiation of these forest wetland characteristics could help enable policymakers to develop sustainable management with the aim of balancing conservation with utilization in ecotourism destinations.
Measuring the Scale and Scope of Workplace Bullying: An Alternative Workplace Bullying Scale
Authors: Anjum Ambreen , Muazzam Amina , Manzoor Farkhanda , Visvizi Anna , Pollock Gary , Nawaz Raheel
Published: August 2019

The toll of workplace bullying is immense, yet, similarly as with an iceberg, its scope, scale and implications tend to remain underestimated. Several ways of assessing the prevalence of workplace bullying have been proposed in the literature. The most frequently discussed are the ‘subjective method’ assessing individuals’ perceptions of being a victim and the questionnaire, i.e., criterion-based, methods, including Negative Acts Questionnaire (NAQ) and Leymann Inventory of Psychological Terror (LIPT). Since in both cases culture plays a profound role as a mediating factor in the process of identifying, collecting, and processing data, the applicability of these methods across cultures and countries has several limitations. At this stage, it is impossible to determine the impact of the implicit cultural-bias that these methods entail on the research outcomes. This would be possible if an alternative workplace bullying scale (WBS) was at hand and, consequently, a comparative analysis was conducted. This paper, drawing from a study conducted at higher education institutions (HEI) across Pakistan, addresses this issue by devising an alternative WBS. The value added of this paper is three-fold, i.e., it elaborates on the study and the specific methods employed to prove the validity and relevance of the alternative WBS. Moreover, by so doing, it addresses some of the limitations that other methods measuring the prevalence of workplace bullying display. As a result, it adds to the researchers’ and administrators’ toolkit as regards research and policies aimed at mitigating the scope and scale of bullying at HEIs across cultures and countries.
Trapping Fake Discounts as Drivers of Real Revenues and Their Impact on Consumer’s Behavior in India: A Case Study
Authors: Hawaldar Iqbal Thonse , Ullal Mithun S. , Birau Felicia Ramona , Spulbar Cristi Marcel
Published: August 2019

This empirical study contributes towards identifying the effect of both fake and real discounts in the Indian marketing environment. A common but unsustainable practice in India is to increase the selling price and then offer a discount on the product. Increasing sales based on fake discount pricing strategy is a primary business development objective in India. The discounts, however, vary across store type and time and are based on product features. The selected databases were collected from the top five Indian e-commerce portals in terms of volume of sales, and from popular brick and motor outlets of tier 2 and tier 3 cities in India. The empirical results indicate that offers based on price in India had an impact of 2.8 times higher than the actual quality of the product. The outcomes suggest that marked price has a significant impact on consumer’s behavior. The results also indicate the existence of a strong correlation between trapping fake discounts and purchase by deceiving and persuading customers in India. Research is empirical in nature and respondents have been selected based on purposive sampling. The study is limited to tier 2 and 3 cities of India for 250 days, and the results are applicable to online and offline retail stores.

Published: August 2019

This paper’s aim is to analyze the challenges that may arise to the harmonious and inclusive economic development of EU member states from Central and Eastern Europe in the larger context of the European Common Market and the free movement of capital. The theoretical framework on which this paper is based is represented by the thesis of “structural dependence on international capital” and “race to the bottom” competition to attract foreign investment and increase the convergence speed in the catching-up process. We have also tackled the consequences arising from the social cohesion perspective, pointing out that a country cannot have at the same time (1) a high degree of social equity; (2) free movement of capital, amid structural consequences that manifest themselves as a result of this freedom; and, (3) a robust position of foreign companies as a share of value added.
Research on the Coupled Risk of Key Nodes in Maritime Transport Based on Improved Catastrophe Theory

Defining the degree of risk of maritime transport nodes is an important basis for studying the security status of maritime transport passages. However, some important straits or canals are key nodes in the maritime transport passage, and their system security conditions are affected by the interaction of uncertainty risk factors. This study addresses the issue of the security status of transport nodes from the perspective of the characteristics of influencing factors. With a focus on catastrophes and the mutual coupling characteristics of the factors that influence the security of maritime transport nodes, a model based on principal component analysis (PCA) and catastrophe theory (CT) is constructed, and the coupled risk degree of the key nodes in Chinese maritime transportation is empirically analysed. The results show that the Taiwan Strait has the lowest risk degree and that the Windward Strait has the highest risk degree among the key nodes in Chinese maritime transport. From the perspective of the security status of these key nodes, most nodes are currently in a stable and safe state.

Microcystins are potent hepatotoxins that have become a global health concern in recent years. Their actions in at-risk populations with pre-existing liver disease is unknown. We tested the hypothesis that the No Observed Adverse Effect Level (NOAEL) of Microcystin-LR (MC-LR) established in healthy mice would cause exacerbation of hepatic injury in a murine model (Leprdb/J) of Non-alcoholic Fatty Liver Disease (NAFLD). Ten-week-old male Leprdb/J mice were gavaged with 50 μg/kg, 100 μg/kg MC-LR or vehicle every 48 h for 4 weeks (n = 15–17 mice/group). Early mortality was observed in both the 50 μg/kg (1/17, 6%), and 100 μg/kg (3/17, 18%) MC-LR exposed mice. MC-LR exposure resulted in significant increases in circulating alkaline phosphatase levels, and histopathological markers of hepatic injury as well as significant upregulation of genes associated with hepatotoxicity, necrosis, nongenotoxic hepatocarcinogenicity and oxidative stress response. In addition, we observed exposure dependent changes in protein phosphorylation sites in pathways involved in inflammation, immune function, and response to oxidative stress. These results demonstrate that exposure to MC-LR at levels that are below the NOAEL established in healthy animals results in significant exacerbation of hepatic injury that is accompanied by genetic and phosphoproteomic dysregulation in key signaling pathways in the livers of NAFLD mice.

Urbanization offers several opportunities for the growth of economic, social, and technology sectors, offering benefits to society in terms of better living and healthcare facilities, as well as employment opportunities. However, some major downsides of urbanization are overcrowding and environmental degradation. In order to realize sustainable and environmentally friendly urbanization, there is an urgent need for comprehensive land use planning and of urban settlements by giving due consideration to create and sustain urban green spaces (UGS) such as parks, gardens, roadside vegetation, etc. UGS play a vital role in reducing air pollution, mitigating climate change, and providing various ecosystem services. UGS are being deteriorated substantially due to booming urbanization in developing countries such as India. This review is focused on highlighting the many challenges in creating and maintaining UGS in the Indian context. It is a compilation of available reports on problems linked with poor land use and/or planning of urban settlements. The challenges associated with the management and maintenance of UGS are described. The poor and irregular watering of many existing UGS is one of the major issues among several others requiring immediate attention to resolve the problem of deteriorating UGS in some cities of India. As the groundwater resources are rapidly depleting because of ever increasing water demand, UGS are being dispensed with poor and irregular watering resulting in their deterioration. A list of possible solutions and prospects of UGS in cities aiming to become smart cities soon are discussed in this review. Efficient wastewater treatment and a non-potable reuse system are possible solutions for better prospects of UGS, and therefore, optimism of better cities with low to null urban heat island effect.

A distinct Russian Mammalian orthorubulavirus 5 (PIV5) was detected in cell culture exhibiting cytopathic effect and hypothesized to be contaminated by a scientist with respiratory symptoms. The identification of the divergent strain indicated a lack of knowledge on the diversity of PIV5 strains and calls for surveillance of global PIV5 strains.

Filoviruses have become a worldwide public health concern, especially during the 2013–2016 Western Africa Ebola virus disease (EVD) outbreak—the largest outbreak, both by number of cases and geographical extension, recorded so far in medical history. EVD is associated with pathologies in several organs, including the liver, kidney, and lung. During the 2013–2016 Western Africa outbreak, Ebola virus (EBOV) was detected in the lung of infected patients suggesting a role in lung pathogenesis. However, little is known about lung pathogenesis and the controversial issue of aerosol transmission in EVD. This review highlights the pulmonary involvement in EVD, with a special focus on the new data emerging from the 2013–2016 Ebola outbreak.
