A Hybrid Method for Mobile Agent Moving Trajectory Scheduling using ACO and PSO in WSNs
Authors: Gao Yu , Wang Jin , Wu Wenbing , Sangaiah Arun Kumar , Lim Se-Jung
Published: January 2019

Wireless Sensor Networks (WSNs) are usually troubled with constrained energy and complicated network topology which can be mitigated by introducing a mobile agent node. Due to the numerous nodes present especially in large scale networks, it is time-consuming for the collector to traverse all nodes, and significant latency exists within the network. Therefore, the moving path of the collector should be well scheduled to achieve a shorter length for efficient data gathering. Much attention has been paid to mobile agent moving trajectory panning, but the result has limitations in terms of energy consumption and network latency. In this paper, we adopt a hybrid method called HM-ACOPSO which combines ant colony optimization (ACO) and particle swarm optimization (PSO) to schedule an efficient moving path for the mobile agent. In HM-ACOPSO, the sensor field is divided into clusters, and the mobile agent traverses the cluster heads (CHs) in a sequence ordered by ACO. The anchor node of each CHs is selected in the range of communication by the mobile agent using PSO based on the traverse sequence. The communication range adjusts dynamically, and the anchor nodes merge in a duplicated covering area for further performance improvement. Numerous simulation results prove that the presented method outperforms some similar works in terms of energy consumption and data gathering efficiency.

Authors: Malecha Karol , Jasińska Laura , Grytsko Anna , Drzozga Kamila , Słobodzian Piotr , Cabaj Joanna
Published: January 2019

This paper compares two types of microfluidic sensors that are designed for operation in ISM (Industrial, Scientific, Medical) bands at microwave frequencies of 2.45 GHz and 5.8 GHz. In the case of the first sensor, the principle of operation is based on the resonance phenomenon in a microwave circuit filled with a test sample. The second sensor is based on the interferometric principle and makes use of the superposition of two coherent microwave signals, where only one goes through a test sample. Both sensors are monolithic structures fabricated using low temperature co-fired ceramics (LTCCs). The LTCC-based microwave-microfluidic sensor properties are examined and compared by measuring their responses for various concentrations of two types of test fluids: one is a mixture of water/ethanol, and the other is dopamine dissolved in a buffer solution. The experiments show a linear response for the LTCC-based microwave-microfluidic sensors as a function of the concentration of the components in both test fluids.

Published: January 2019

The resonant wave modes in monomodal and multimodal planar Surface Plasmon Resonance (SPR) sensors and their response to a bidimensional array of gold nanoparticles (AuNPs) are analyzed both theoretically and experimentally, to investigate the parameters that rule the correct nanoparticle counting in the emerging metal nanoparticle-amplified surface plasmon resonance (PA-SPR) spectroscopy. With numerical simulations based on the Finite Element Method (FEM), we evaluate the error performed in the determination of the surface density of nanoparticles σ when the Maxwell-Garnett effective medium theory is used for fast data processing of the SPR reflectivity curves upon nanoparticle detection. The deviation increases directly with the manifestations of non-negligible scattering cross-section of the single nanoparticle, dipole-dipole interactions between adjacent AuNPs and dipolar interactions with the metal substrate. Near field simulations show clearly the set-up of dipolar interactions when the dielectric thickness is smaller than 10 nm and confirm that the anomalous dispersion usually observed experimentally is due to the failure of the effective medium theories. Using citrate stabilized AuNPs with a nominal diameter of about 15 nm, we demonstrate experimentally that Dielectric Loaded Waveguides (DLWGs) can be used as accurate nanocounters in the range of surface density between 20 and 200 NP/µm2, opening the way to the use of PA-SPR spectroscopy on systems mimicking the physiological cell membranes on SiO2 supports.
Improving GNSS PPP Convergence: The Case of Atmospheric-Constrained, Multi-GNSS PPP-AR
Authors: Aggrey John , Bisnath Sunil
Published: January 2019

GNSS positioning performance has been shown to improve with the ingestion of data from Global Ionospheric Maps (GIMs) and tropospheric zenith path delays, which are produced by, e.g., the International GNSS Service (IGS). For both dual- and triple-frequency Precise Point Positioning (PPP) processing, the significance of GIM and tropospheric products in processing is not obvious in the quality of the solution after a few hours. However, constraining the atmosphere improves PPP initialization and solution convergence in the first few minutes of processing. The general research question to be answered is whether there is any significant benefit in constraining the atmosphere in multi-frequency PPP? A key related question is: regarding time and position accuracy, how close are we to RTK performance in the age of multi-GNSS PPP-AR? To address these questions, this paper provides insight into the conceptual analyses of atmospheric GNSS PPP constraints. Dual- and triple-frequency scenarios were investigated. Over 60% improvement in convergence time was observed when atmospheric constraints are applied to a dual-frequency multi-GNSS PPP-AR solution. Future work would involve employing the constraints to improve low-cost PPP solutions.
A Precise Diagnosis Method of Structural Faults of Rotating Machinery based on Combination of Empirical Mode Decomposition, Sample Entropy, and Deep Belief Network
Authors: Guan Zhaoyi , Liao Zhiqiang , Li Ke , Chen Peng
Published: January 2019

To precisely diagnose the rotating machinery structural faults, especially structural faults under low rotating speeds, a novel scheme based on combination of empirical mode decomposition (EMD), sample entropy, and deep belief network (DBN) is proposed in this paper. EMD can decompose a signal into several intrinsic mode functions (IMFs) with different signal-to-noise ratios (SNRs) and sample entropy is performed to extract the signals that carry fault information with high SNR. The extracted fault signal is reconstructed into a new vibration signal that will carry abundant fault information. DBN has strong feature extraction and classification performance. It is suitably performed to build the diagnosis model based on the reconstructed signal. The effectiveness of the proposed method is validated by structural faults signal and the comparative experiments (BPNN, CNN, time-domain signal only, frequency-domain signal only). The results show that the diagnosis accuracy of the proposed method is between 99% and 100%, the BPNN is less than 25%, and the CNN is between 70% and 95%, which means the verified, proposed method has a superior performance to diagnose the structural fault.
Quantifying Risk in Traditional Energy and Sustainable Investments
Authors: Díaz Antonio , García-Donato Gonzalo , Mora-Valencia Andrés
Published: January 2019

These days we are witnessing a deep change in the characteristics of the type of energy that our economies are supplied with. A clear trend is that sustainable and green energies are decisively replacing traditional fossil fuel-based sources of energy. For various reasons, this fundamental change implies an increasing risk in investments on portfolios heavily based on traditional energy industries. What is less known, is that these industries have returns that show a very low correlation with sustainable fossil fuel-free stock portfolios making them an appealing tool for portfolio managers to design properly diversified investments. In this study we examine this and related phenomena proposing statistical methods to implement the expected shortfall (ES), the challenging risk measure recently adopted by the financial regulator. We obtain evidence that a newly proposed backtesting procedure for the ES based on multinomial tests is an adequate and simple method to validate these risk measures when applied to a highly volatile stock index. Backtesting results of the ES show that flexible heavy-tailed distribution α–stable performs well for modelling the loss distribution. These results are even improved when the variances of fossil fuel price returns are included as external regressors in the GARCH model variance equation. In this case, the ES computed from the four considered loss distributions perform properly.

Authors: Na Youn Kue , Kang Sungmin , Jeong Hye Yeon
Published: January 2019

This study investigated relationships among the market orientation of sharing economy business, marketing innovation, sustainable competitive advantage (SCA), and performance. Attempts are made to understand market orientation from cultural and behavioral perspectives to accelerate marketing innovation and identify measures for SCA and performance building. Frequency, reliability, validity, fitness, and path analyses were performed on 400 respondents, and a structural model was used. The results are as follows. First, functional coordination of the cultural market orientation of sharing economy business with consumer orientation significantly affected product innovation, but competitive orientation’s effect on product innovation was not significant. Competitive orientation and functional coordination significantly affected communication innovation, but consumer orientation’s effect on communication innovation was not significant. Second, market information generation and response to market information of behavioral market orientation of sharing economy business significantly influenced product innovation, but market information exchange’s influence on product innovation was not significant. Even though market information exchange and response to market information had a significant influence on communication innovation, the influence of market information generation on communication innovation was not significant. Third, both product and communication innovation of the marketing innovation of sharing economy business significantly influenced SCA. Fourth, the SCA of sharing economy business significantly influenced market dominating power.
The Effect of Deep N+ Well on Single-Event Transient in 65 nm Triple-Well NMOSFET
Authors: Zhang Jizuo , Chen Jianjun , Huang Pengcheng , Li Shouping , Fang Liang
Published: January 2019

In a triple-well NMOSFET, a deep n+ well (DNW) is buried in the substrate to isolate the substrate noise. The presence of this deep n+ well leads to changes in single-event transient effects compared to bulk NMOSFET. In space, a single cosmic particle can deposit enough charge in the sensitive volume of a semiconductor device to cause a potential change in the transient state, that is, a single-event transient (SET). In this study, a quantitative characterization of the effect of a DNW on a SET in a 65 nm triple-well NMOSFET was performed using heavy ion experiments. Compared with a bulk NMOSFET, the experimental data show that the percentages of average increase of a SET pulse width are 22% (at linear energy transfer (LET) = 37.4 MeV·cm2/mg) and 23% (at LET = 22.2 MeV·cm2/mg) in a triple-well NMOSFET. This study indicates that a triple-well NMOSFET is more sensitive to a SET, which means that it may not be appropriate for radiation hardened integrated circuit design compared with a bulk NMOSFET.
Leveraging Digital Twin Technology in Model-Based Systems Engineering
Authors: Madni Azad M. , Madni Carla C. , Lucero Scott D.
Published: January 2019

Digital twin, a concept introduced in 2002, is becoming increasingly relevant to systems engineering and, more specifically, to model-based system engineering (MBSE). A digital twin, like a virtual prototype, is a dynamic digital representation of a physical system. However, unlike a virtual prototype, a digital twin is a virtual instance of a physical system (twin) that is continually updated with the latter’s performance, maintenance, and health status data throughout the physical system’s life cycle. This paper presents an overall vision and rationale for incorporating digital twin technology into MBSE. The paper discusses the benefits of integrating digital twins with system simulation and Internet of Things (IoT) in support of MBSE and provides specific examples of the use and benefits of digital twin technology in different industries. It concludes with a recommendation to make digital twin technology an integral part of MBSE methodology and experimentation testbeds.
Sediments from Arctic Tide-Water Glaciers Remove Coastal Marine Viruses and Delay Host Infection
Authors: Maat Douwe S. , Prins Maarten A. , Brussaard Corina P. D.
Published: January 2019

Over the past few decades, the Arctic region has been strongly affected by global warming, leading to increased sea surface temperatures and melting of land and sea ice. Marine terminating (tide-water) glaciers are expected to show higher melting and calving rates, with an increase in the input of fine sediment particles in the coastal marine environment. We experimentally investigated whether marine viruses, which drive microbial interactions and biogeochemical cycling are removed from the water column through adsorption to glacier-delivered fine sediments. Ecologically relevant concentrations of 30, 100 and 200 mg·L−1 sediments were added to filtered lysates of 3 cultured algal viruses and to a natural marine bacterial virus community. Total virus removal increased with sediment concentration whereby the removal rate depended on the virus used (up to 88% for an Arctic algal virus), suggesting a different interaction strength with the sediment. Moreover, we observed that the adsorption of viruses to sediment is a reversible process, and that desorbed viruses are still able to infect their respective hosts. Nonetheless, the addition of sediment to infection experiments with the Arctic prasinovirus MpoV-45T substantially delayed host lysis and the production of progeny viruses. We demonstrate that glacier-derived fine sediments have the potency to alter virus availability and consequently, host population dynamics.

Authors: Chutora Taras , de la Torre Bruno , Mutombo Pingo , Hellerstedt Jack , Kopeček Jaromír , Jelínek Pavel , Švec Martin
Published: January 2019

We investigate the possibility of functionalizing Au tips by N2O molecules deposited on a Au(111) surface and their further use for imaging with submolecular resolution. First, we characterize the adsorption of the N2O species on Au(111) by means of atomic force microscopy with CO-functionalized tips and density functional theory (DFT) simulations. Subsequently we devise a method of attaching a single N2O to a metal tip apex and benchmark its high-resolution imaging and spectroscopic capabilities using FePc molecules. Our results demonstrate the feasibility of high-resolution imaging. However, we find an inherent asymmetry of the N2O probe-particle adsorption on the tip apex, in contrast to a CO tip reference. These findings are consistent with DFT calculations of the N2O- and CO tip apexes.
Synthesis of 1,2-divinylcyclopropanes by metal-catalyzed cyclopropanation of 1,3-dienes with cyclopropenes as vinyl carbene precursors
Authors: González Jesús , de la Fuente Alba , González María J , Díez de Tejada Laura , López Luis A , Vicente Rubén
Published: January 2019

The synthesis of 1,2-divinylcyclopropanes by the reaction of cyclopropenes with 1,3-dienes is reported. The process relies on the ability of ZnCl2 or [Rh2(OAc)4] to generate metal–vinyl carbene intermediates from cyclopropenes, which effect cyclopropanation of 1,3-dienes. Most of the reactions proceeded in reasonable yields while the diastereoselectivity strongly depends on the structure of the diene. An example of an intramolecular process as well as the use of furan and 1,4-cyclohexadiene as dienes are also reported.

De l’espoir dans le tragique. Quand l’agir procure du sens à une vie
Authors: Monette Marcelle , Quintin Jacques
Published: January 2019

L’expérience de la maladie entraîne une désorientation, une perte de sens et de liberté d’agir. C’est tout le champ des possibilités pratiques qui diminue avec comme résultat une expérience de l’action comme quelque chose d’impossible. Dans ce cas, la question est la suivante : l’infirmière peut-elle contribuer à maintenir un espoir d’une vie riche de sens, ajusté aux limites imposées par la maladie ? Nous proposons, dans ce contexte, un modèle humaniste d’accompagnement qui permet aux infirmières de redonner de l’espoir et du pouvoir aux personnes en situation de vulnérabilité. En examinant le meilleur et le pire scénario qui pourrait survenir chez la personne vulnérable, la méthode d’accompagnement proposée met l’accent sur l’exploration d’interventions pratiques qui pourraient favoriser le meilleur scénario et réduire le risque et les conséquences du pire scénario. En travaillant sur certains aspects pragmatiques, nous constatons que la vie prend sens selon l’usage qu’on peut en faire, eu égard aux possibilités d’action.

Le Sentier Lumineux : un laboratoire pour l’étude du terrorisme
Authors: Dory Daniel
Published: January 2019

Cet article montre l’importance du Sentier Lumineux (SL) pour l’analyse du fait terroriste à partir de deux approches. D’une part l’évaluation de la littérature récente consacrée au procès insurrectionnel que cette organisation a conduit au Pérou à partir de 1980. D’autre part une analyse de la place de SL dans les bases de données, bibliographies et autres instruments de travail à la disposition des chercheurs en matière de terrorisme. A partir de ce cas, des propositions sur les définitions et les fonctions du terrorisme sont proposées, avec des implications directement pertinentes pour la compréhension du terrorisme contemporain et, donc, pour les stratégies destinées à le combattre.
Prévenance de la sagesse et désir de l’homme. Le mystère de la relation entre Dieu et l’homme selon Sagesse de Salomon 6,12-16
Authors: Beaubœuf Stéphane
Published: January 2019

Dans un poème qui reprend le thème sapientiel traditionnel de la recherche de la sagesse (Sg 6,12-16), l’auteur de la Sagesse de Salomon écrit : « Celui qui s’est levé tôt pour elle ne peinera pas, car il la trouvera assise à sa porte » (6,14). Grâce à l’initiative de la sagesse, la recherche est on ne peut plus facile et aboutit presque instantanément. En examinant la structure complexe du poème, cette étude se propose de montrer comment l’auteur cherche à articuler cette « prévenance » avec l’initiative propre de l’homme et comment, au moyen d’une ambiguïté syntaxique, morphologique et lexicale, il parvient à présenter la relation entre Dieu et l’homme comme le fruit d’un délicat équilibre entre asymétrie et complémentarité.
Vers une nouvelle manière d’appréhender l’Histoire et de comprendre la géopolitique ?
Authors: Buchet Christian
Published: January 2019

Océanides est par son ampleur le programme en sciences humaines le plus conséquent depuis la Grande Encyclopédie du xviii e siècle pour avoir réuni 260 chercheurs issus de 40 pays. L’ambition et l’originalité de ce programme international de recherche de cinq années a été d’évaluer l’impact du fait maritime dans l’Histoire de l’humanité, de la préhistoire jusqu’à aujourd’hui. De l’ensemble de ces recherches publiées in extenso en quatre volumes, en français et en anglais, par les éditions Boydell and Brewer, se dégagent trois vagues de fond qui répondent clairement à notre questionnement. Oui, le fait de se tourner vers la mer quel que soit le temps, le lieu, est le moteur le plus puissant qui soit pour impacter positivement les trajectoires historiques. C’est que la mer est le moteur de la prédominance et du rayonnement, l’accélérateur du développement économique et politique, et le moteur de l’Histoire. Une vision qui bouleverse toute la géopolitique qui s’est jusqu’ici toujours focalisée sur l’histoire terrienne, voire la structuration de l’Histoire universelle.

The Different Roles of Help-Seeking Personalities in Social Support Group Activity on E-Portfolio for Career Development
Authors: Wetcho Suthanit , Na-Songkhla Jaitip
Published: January 2019

Social Support plays a crucial role between recipients and service providers. It is a strong contributor in reducing the level of uncertainty in a situation, in both relationships with one’s own self, as well as relationships on other levels. It can also be used within a group activity system such as E-Portfolio development. One example of this being the support provided to learners who have reflected on their own experience during a period of transition. However, it is possible that some of the learners who participated in the social support group activity may not have been familiar with the community and may have acted differently, changing their help-seeking style within the group. This research used Activity theory as a tool to define the activity structure and aimed to focus on the working behavior among members of a social support group with different help-seeking personalities. The experiment also revealed the effects of E-portfolio development on self-efficacy skills in career-based decision-making, based on different help-seeking personalities using Pretest–Posttest Nonequivalent Control Group design. Upper secondary school students in Thailand were used as the population in the research. Participants in this study were also students under Royal patronage in grade 11 (n = 80) and there were students from each region of Thailand. These participants attended the guidance and preparation summer camp in collaboration with Chulalongkorn University. It is revealed by the findings that the statistically significant difference is at the level of .05 in Autonomous help-seeking learners and within the subgroup 3, which included Autonomous and Dependent help-seeking learners. The help-seeking personality working styles in the support group are discussed.

The Influence of Internal Audit on External Audit
Authors: Silva Ana , Inácio Helena , Vieira Elisabete
Published: January 2019

The main purpose of this chapter is to analyze the relationship between internal and external audit and its effect on external audit fees, through a questionnaire addressed to the external auditors of Portugal and Spain. It obtained 131 answers for Portugal and 149 answers for Spain. According to the results, the competencies and characteristics of internal auditors, as well as the type of activities performed by them and the communication between internal and external auditors, have a significant influence on the decision of using the internal audit work. However, the Portuguese external auditors do not consider this influence to be so significant that it affects the number of substantive tests, the quality of external audit, and external audit fees. However, for Spanish auditors using internal audits decreases the planned hours, the number of control and substantive tests, and improves external audit quality, but does not reflect in the fees to be charged to the client.

Published: January 2019

The audit expectation gap (AEG) is present in society and, while there, will encourage discrediting the auditors. Given the seriousness of this situation, several solutions have been pointed out, one of which is to promote audit education. The aim of this chapter is to verify if adult education, taught at the Polytechnic Institute of Cávado and Ave (IPCA), reduces the AEG, considering the perceptions of its students about the role assigned to the auditors and the degree of success of the auditors in certain situations. The application of a questionnaire allowed to conclude that, as the literature review showed, audit education changes the perceptions of IPCA students about the role and degree of success of the auditors, generally reducing the AEG.

Authors: Çabuk Adem , Aytaç Alp
Published: January 2019

Massive usage of internet and digital devices make it easier accessing the desired information. In the past, auditing was a periodic, reactive approach, but this must change. Today, volume, velocity, variety, veracity, and value of the information, which are the main criteria of big data, are crucial. Decision makers demand timely, true, and reliable information. This need has affected every sector including auditing. For this reason, the continuous auditing system comes to debate in the big data era. The main aim of this chapter is to shed light on how traditional auditing transformed into the continuous auditing and where big data stands in this transformation. It is concluded that even though many obstacles arise, continuous auditing systems and harvesting big data benefits are crucial to gain a competitive advantage. Also, using big data analytics and continuous auditing system together, management and shareholders gain detailed information about the company's present situation and future direction.
Boosting Football Club Brands Through Museums

Learning to program is an important subject in computer science courses. During programming exercises, plagiarism by copying and pasting can lead to problems for fair evaluation. Some methods of plagiarism detection are currently available, such as sim. However, because sim is easily influenced by changing the identifier or program statement order, it fails to do enough to support plagiarism detection. In this paper, the authors propose a plagiarism detection method which is not influenced by changing the identifier or program statement order. The authors also explain our method's capabilities by comparing it to the sim plagiarism detector. Furthermore, the authors reveal how our method successfully detects the presence of plagiarism.

In the last decade, the plagiarism cases were increased and become a topical problem in the modern scientific world, caused by the quantity of textual information available online/offline. The authors' work deals on the development of a new plagiarism detector system called BHA2 which has as input the suspicious text (to be analysed) and the original texts (learning basis). It can detect the different forms of plagiarism based on: Google API to detect the cases of plagiarism with translation; text summarization to detect the plagiarism of idea; conceptual transformation to detect the plagiarism with synonymy; bag of phrases to detect the paraphraser plagiarism; the social worker bees algorithm that was inspired from the lifestyle of social worker bees (forager, guardian, and cleaner) to select the documents source of plagiarism; the output of the authors' system are the plagiarised passages (the copied parts from the original texts) and the plagiarism percentage for each suspicious text. Their experiments were performed on the Pan 09 dataset and using the validation measures (recall, precision, accuracy, error, f-measure, and entropy, FPR, FNR, W-accuracy, ROC and TCR) in order to show the benefit derived from using such idea compared to the result of classical systems existed in literature. A comparative study in term of services was realised between their system and others commercial systems such as (check, Turnitin, and machine learning system) with their system. Finally, a visualization step was achieved for the purpose to see the outcome in graphical form (3d cub and cobweb) with more realism using the functionalities of zooming and rotation.
Plagiarism vs. Pedagogy

Published: January 2019

Plagiarism research has demonstrated the prevalence of this practice as well as its relationship to various individual and contextual factors. This research has been conducted in traditional educational contexts emphasizing teacher authority and knowledge acquisition with limited student autonomy, voice and choice. In this chapter, the authors explore the possibility of changing the educational context in order to diminish plagiarism. Project-Based Learning (PBL) is suggested as a way not only to reduce plagiarism, but to also teach for deep understanding and promote students' acquisition of 21st Century Skills. PBL emphasizes building a team-centered learning culture, using authentic and creative projects presented to an audience, and changing classroom norms to encourage positive student behavior. We discuss the implications for the classroom roles of staff and students, and the need for preparing teachers to use PBL instructional methodologies in their classrooms.
Awareness of Plagiarism

Evaluating students by giving them assignments and projects is essential for their learning. Yet the validity of this assessment can be threatened by the serious problem of plagiarism. Researchers have found that copying another's work is very common in schools (Decoo, 2002) and is caused by several factors. Curiously, most prominent among these is lack of awareness of what plagiarism is (Pritchett, 2010). Thus, this chapter tries to measure this awareness among English students in a Foundation Program at Oman's Sultan Qaboos University and determine how their teachers deal with it. The sample included 40 English Foundation students (20 males and 20 females) and 20 instructors (10 males and 10 females). A questionnaire revealed that these students lacked awareness of plagiarism because its meaning had not been explained at school. Participants thus suggested receiving more instruction about proper citation and quotation as one solution to the problem. Instructors dealt with plagiarism in different ways, with such penalties as deducting marks the most common. Moreover, a negative relationship was found between students' academic proficiency and their willingness to plagiarize. To help these Foundation students to avoid facing difficulties in higher education, the study suggested teaching them, while still in school, how to cite, quote, and use references without plagiarizing.
Ensuring Research Integrity
Authors: Ovia Ebikaboere
Published: January 2019

Ethics is the study of man's internalization of his understanding of terms such as value, dignity, integrity, fairness, justice, and care among others. These terms are relevant to man in his private as well as public life, in official and unofficial settings. Man must realize that he interacts with others either on one-on-one basis or through other materials, which include recorded voice, written documents, speeches made, interviews granted, and the like. He must take cognizance of his sense of morality therefore or become immoral, that is using people solely to achieve his purpose, or worse still degenerate to being amoral. Where a researcher is indifferent to the impact of his work on others, his research base or benefactors, he is an egoist. In order to assist the researcher, journalist, teacher, etc. every organization, institute, corporation, etc. must have laid down rules generally referred to as “code of conduct.” These must be binding on all members, serving as a guide to members' behaviors in their day-to-day interactions.
Research and Web 2.0
Authors: Ponte Diego , Klein Stefan
Published: January 2019

The scientific publishing industry has witnessed a plethora of innovations across the life cycle of writing, publishing and archiving of scientific journals. Open access is only the visible tip of an iceberg that contains new players and new services and modes of publishing—which span from new review processes, online citation indexes and social media tools—that have become available over the past 20 years. One might have the impression that disruptive innovations are underway and that many of the well-established themes of digital transformation, such as business model and service innovation, disintermediation, ProSuming and new pricing models, have had a profound impact on the market of scientific journals. Nonetheless, the commercial academic publishing houses (the incumbents) so far have not only successfully defended but even extended their market position. By categorizing the innovations underway and relating them to the constellation of actors in this market, the authors reflect on and try to explain the lasting influence of traditional publishers in the market.
Quality Assessment and Certification in Open Scholarly Publishing and Inspiration for MOOC Credentialing
Authors: Ren Xiang
Published: January 2019

This chapter looks at the changing landscape of quality assessment and certification/credentialing in open knowledge systems by a comparative study between open publishing and open education. Despite the disruptive changes driven by open publishing in scholarly communication, it is challenging to develop widely accepted methods for quality assessment and certification. Similar challenges exist in open education platforms like the massive open online course (MOOC). This work reviews four types of innovations in open publishing in terms of quality control, namely “light touch” peer review, post-publication assessment, social peer review, and open peer review. Synthesising the principles and strategies of these innovations, it discusses how they might be inspiring for developing solutions and models for MOOC assessment and credentialing. This chapter concludes by suggesting future research directions. It argues that the open initiatives are co-evolving with the “traditional” systems and integrating with the established models.
Design and Implementation for Controlling Multiple Robotic Systems by a Single Operator Under Random Communication Delays
Authors: Jia Yunyi
Published: January 2019

Multiple robots can be tele-operated by a single operator to accomplish complicated tasks such as formation and co-transportation. Such systems are challenging because one operator needs to simultaneously tele-control multiple homogeneous and even heterogeneous robots. Besides, the communication between the operator and multi-robot system and the communication among the multiple robots are always subject to some communication constraints such as time delays. This chapter introduces a novel non-time based method to realize the single-operator-multi-robot (SOMR) teleoperation system with random communication delays. The problem is divided into a typical teleoperation problem and a multi-robot coordination problem. A non-time variable is taken as the system reference instead of the time to model and drive the system such that the random communication delays and some expected events could be automatically handled. Experiments implemented on a multi-robot system illustrate the effectiveness and advantages of the method.
