Isothermal Adsorption Properties for the Adsorption and Removal of Reactive Blue 221 Dye from Aqueous Solutions by Cross-Linked β-Chitosan Glycan as Acid-Resistant Adsorbent
Authors: Chiu Chih-Wei , Wu Ming-Tsung , Lee Jimmy , Cheng Ting-Yu
Published: November 2018

Dye effluent causes serious pollution and damage to the environment and needs a series of treatments before it can be discharged. Among the numerous effluent treatment methods, adsorption is the simplest and does not cause secondary pollution. Bio-adsorbents are especially advantageous in the treatment of low-concentration dye effluent. In this study, the adsorption and removal capacities of unmodified α- and β-chitosan and modified β-chitosan (β-chitosan cross-linked with triethylenetetramine, BCCT) on C.I. Reactive Blue 221 (RB221) dye were compared. The experiments were performed on the adsorption of the RB221 dye by unmodified α- and β-chitosan and cross-linkage–modified BCCT at different temperatures and for different durations, which are presented along with the relevant adsorption kinetics calculations. According to the results, as the temperature increased from 303 to 333 K, the initial adsorption rates of the adsorbents, α-chitosan, β-chitosan, and BCCT, for the RB221 dye, changed from 1.01 × 102, 4.74 × 102, and 1.48 × 106 mg/g min to 5.98 × 104, 4.23 × 108, and 1.52 × 1013 mg/g min, respectively. BCCT thus showed the best adsorption for the dye at all temperatures from the Elovich model. These results confirmed the successful introduction of a polyaminated and cross-linked extended structure as a modification for the BCCT adsorbent, which makes it resistant to acid hydrolysis and gives it the functional amine group for dye adsorption, thereby promoting the ability of BCCT to adsorb dyes under strongly acidic conditions. The compound synthesized in this study is expected to be a good choice in the future for purifying strongly acidic effluent containing anionic organic dyes.

Published: November 2018

The vacant house is an essential phenomenon of urban decay and population loss. Exploration of the correlations between housing vacancy and some socio-environmental factors is conducive to understanding the mechanism of urban shrinking and revitalization. In recent years, rapidly developing night-time remote sensing, which has the ability to detect artificial lights, has been widely applied in applications associated with human activities. Current night-time remote sensing studies on housing vacancy rates are limited by the coarse spatial resolution of data. The launch of the Jilin1-03 satellite, which carried a high spatial resolution (HSR) night-time imaging camera, provides a new supportive data source. In this paper, we examined this new high spatial resolution night-time light dataset in housing vacancy rate estimation. Specifically, a stepwise multivariable linear regression model was engaged to estimate the housing vacancy rate at a very fine scale, the census tract level. Three types of variables derived from geospatial data and night-time image represent the physical environment, landuse (LU) structure, and human activities, respectively. The linear regression models were constructed and analyzed. The analysis results show that (1) the HVRs estimating model using the Jilin1-03 satellite and other ancillary geospatial data fits well with the Census statistical data (adjusted R2 = 0.656, predicted R2 = 0.603, RMSE = 0.046) and thus is a valid estimation model; (2) the Jilin1-03 satellite night-time data contributed a 28% (from 0.510 to 0.656) fitting accuracy increase and a 68% (from 0.359 to 0.603) predicting accuracy increase in the estimate model of the housing vacancy rate. Reflecting socio-economic conditions, the luminous intensity of commercial areas derived from the Jilin1-03 satellite is the most influential variable to housing vacancy. Land use structure indirectly and partially demonstrated that the social environment factors in the community have strong correlations with residential vacancy. Moreover, the physical environment factor, which depicts vegetation conditions in the residential areas, is also a significant indicator of housing vacancy. In conclusion, the emergence of HSR night light data opens a new door to future microscopic scale study within cities.
DSM-to-LoD2: Spaceborne Stereo Digital Surface Model Refinement
Authors: Bittner Ksenia , D’Angelo Pablo , Körner Marco , Reinartz Peter
Published: November 2018

A digital surface model (DSM) provides the geometry and structure of an urban environment with buildings being the most prominent objects in it. Built-up areas change with time due to the rapid expansion of cities. New buildings are being built, existing ones are expanded, and old buildings are torn down. As a result, 3D surface models can increase the understanding and explanation of complex urban scenarios. They are very useful in numerous fields of remote sensing applications, in tasks related to 3D reconstruction and city modeling, planning, visualization, disaster management, navigation, and decision-making, among others. DSMs are typically derived from various acquisition techniques, like photogrammetry, laser scanning, or synthetic aperture radar (SAR). The generation of DSMs from very high resolution optical stereo satellite imagery leads to high resolution DSMs which often suffer from mismatches, missing values, or blunders, resulting in coarse building shape representation. To overcome these problems, we propose a method for 3D surface model generation with refined building shapes to level of detail (LoD) 2 from stereo half-meter resolution satellite DSMs using deep learning techniques. Mainly, we train a conditional generative adversarial network (cGAN) with an objective function based on least square residuals to generate an accurate LoD2-like DSM with enhanced 3D object shapes directly from the noisy stereo DSM input. In addition, to achieve close to LoD2 shapes of buildings, we introduce a new approach to generate an artificial DSM with accurate and realistic building geometries from city geography markup language (CityGML) data, on which we later perform a training of the proposed cGAN architecture. The experimental results demonstrate the strong potential to create large-scale remote sensing elevation models where the buildings exhibit better-quality shapes and roof forms than just using the matching process. Moreover, the developed model is successfully applied to a different city that is unseen during the training to show its generalization capacity.
3D Radiation Pattern Reconfigurable Phased Array for Transmission Angle Sensing in 5G Mobile Communication
Authors: Zhang Jin , Zhang Shuai , Lin Xianqi , Fan Yong , Pedersen Gert Frølund
Published: November 2018

This paper proposes a 3D radiation pattern reconfigurable antenna (RPRA) and a reconfigurable phased array (RPA) for 5G mobile communication. The antenna and array are working at 28 GHz, which is selected as a 5G communication band in many countries. The proposed phased array will be applied as sensors to find out the optimal transmitting–receiving angle in a randomly changed cellular wireless scenarios. The RPRA and RPA are fed by Substrate Integrated Waveguide (SIW) and have three switchable radiation modes: Broadside 1, Broadside 2 and Endfire. The three modes correspond to three different radiation patterns and each of them covers a different area in the Azimuth plane. An eight-element phased array constructed by the proposed RPRA, which is able to switch beam in Azimuth plane and scan in the Elevation plane, is also presented in this paper. The proposed RPA is able to provide much higher spatial coverage than the conventional phased arrays and without additional feeding and phase shifting networks. The beam switching is realized by the PIN diodes. The proposed antenna and array have planer structures and require small clearance on the ground plane which makes them compatible with mobile phones. The simulations show good performance for both RPRA and RPA.
Online Prediction of Ship Behavior with Automatic Identification System Sensor Data Using Bidirectional Long Short-Term Memory Recurrent Neural Network
Authors: Gao Miao , Shi Guoyou , Li Shuang
Published: November 2018

The real-time prediction of ship behavior plays an important role in navigation and intelligent collision avoidance systems. This study developed an online real-time ship behavior prediction model by constructing a bidirectional long short-term memory recurrent neural network (BI-LSTM-RNN) that is suitable for automatic identification system (AIS) date and time sequential characteristics, and for online parameter adjustment. The bidirectional structure enhanced the relevance between historical and future data, thus improving the prediction accuracy. Through the “forget gate” of the long short-term memory (LSTM) unit, the common behavioral patterns were remembered and unique behaviors were forgotten, improving the universality of the model. The BI-LSTM-RNN was trained using 2015 AIS data from Tianjin Port waters. The results indicate that the BI-LSTM-RNN effectively predicted the navigational behaviors of ships. This study contributes significantly to the increased efficiency and safety of sea operations. The proposed method could potentially be applied as the predictive foundation for various intelligent systems, including intelligent collision avoidance, vessel route planning, operational efficiency estimation, and anomaly detection systems.

The analysis of our previous studies on the search for synthetic analgesics among N-R-amides of bicyclic hetaryl-3-carboxylic acids has been performed; on its basis N-hetaryl(aryl)-alkyl-4-methyl-2,2-dioxo-1H-2λ6,1-benzothiazine-3-carboxamides have been selected as new study objects. The “one pot synthesis” of these compounds, which is simple to perform and at the same time highly effective, has been offered. The method consists in the initial reaction of 4-methyl-2,2-dioxo-1H-2λ6,1-benzothiazine-3-carboxylic acid and N,N′-carbonyldiimidazole in anhydrous N,N-dimethylformamide with the subsequent amidation of imidazolide formed with hetarylalkyl- or benzylamines in the same solvent. The peculiarities of 1H- and 13C-NMR spectra of the substances obtained, as well as their electrospray ionization liquid chromato-mass spectra are discussed. According to the results of the pharmacological tests carried out on the model of carrageenan inflammation it has been found that all without exception N-hetaryl(aryl)alkyl-4-methyl-2,2-dioxo-1H-2λ6,1-benzothiazine-3-carboxamides demonstrate the statistically significant analgesic and anti-inflammatory properties. Among the substances presented in this article analgesics and antiphlogistics, which increase the pain threshold and suppress the inflammatory response more effectively than Lornoxicam and Diclofenac in the same doses, have been identified. The molecular and crystal structures of a large group of the substances synthesized have been studied by X-ray diffraction analysis. Comparison of these data with the results of biological tests has revealed the fact of excellent correlation between the molecular conformations of N-hetaryl(aryl)alkyl-4-methyl-2,2-dioxo-1H-2λ6,1-benzothiazine-3-carboxamides recorded in the crystal and the potency of their analgesic effect. N-Thiophen-2-ylmethyl- and N-4-methoxybenzyl-amides of 4-methyl-2,2-dioxo-1H-2λ6,1-benzothiazine-3-carboxylic acid has shown a high analgesic and anti-inflammatory effect, therefore, they deserve more careful research.

A Hybrid HFACS-BN Model for Analysis of Mongolian Aviation Professionals’ Awareness of Human Factors Related to Aviation Safety
Authors: Zhou Tuqiang , Zhang Junyi , Baasansuren Dashzeveg
Published: November 2018

Safety is crucial to ensure the sustainability of aviation growth. To better clarify the influences of human factors on aviation accident risks, this study developed a hybrid HFACS-BN model (HFACS: Human Factors Analysis and Classification System; BN: Bayesian Network). The authors designed and implemented a questionnaire survey based on the four-level HFACS framework and collected valid data from 180 out of 649 aviation professionals working in the Ulaanbaatar International Airport, Mongolian in 2017. The model identified 35 major human factors out of 129 factors. The model validation was performed in terms of content validity and predictive validity. The results showed that even though a majority of respondents perceived that many human factors had a middle- or high-effect on aviation accident risks, the probability of the risks caused by human factors was estimated to be just 1.37%. The Unsafe Acts level is most influential to the risks among the four levels, while the Unsafe Supervision level contributes least. It is revealed that enhancing aviation professionals’ awareness of human factors should make full use of causal chaining effects among human factors. Finally, this study contributes to the literature from the perspectives of both methodological development and important empirical analysis.
What Are the Effects of Participation in Production Outsourcing? Evidence from Chinese Apple Farmers
Authors: Zhang Qiangqiang , Yan Beibei , Huo Xuexi
Published: November 2018

Outsourcing, as a productive service, has been widely adopted in industrial production and international trade but less applied in agricultural management. With the advancement of agricultural labor division and specialization, outsourcing is becoming one of the most sustained trends in concurrent business. This study used a multiple linear regression and a propensity score matching model to quantify the different effects of participation in production outsourcing on farmers’ apple production efficiency and apple income based on field survey data from 960 apple farmers in the Shandong, Shaanxi, and Gansu Provinces. The results showed that, on average, the outsourcing of apple production increased farmers’ apple production technology efficiency by 5.60%, their labor productivity by 2121.48 kg/person, land productivity by 334.50 kg/mu, capital productivity by 0.05 kg/Yuan, and apple sales revenue by 13,300 Yuan. However, farmers’ net income from apples decreased by an average of 5000 Yuan. The outsourcing of apple production, which is labor-intensive, is constrained by the increase in labor costs, which, in turn, affect the transformation of the apple industry into a service-scale operation driven by the economy of division.

La jadéite dans le métamorphisme alpin, à propos des gisements de type nouveau, de la bande d'Acceglio (Alpes cottiennes, Italie)
Authors: Lefèvre Roger , Michard André
Published: November 2018

Cette étude apporte l'exemple d'un gisement de jadéite de type inédit et tend à préciser la définition du métamorphisme tertiaire, pluriphasé, des Alpes occidentales. Dans la bande écaillée d'Acceglio, la jadéite se trouve dans un complexe rhyolitique permien, notamment sous forme d'épigénies de phénocristaux de feldspaths potassiques, sans doute préalablement albitisés.

A part cette particularité, caractères minéralogiques de la jadéite et paragenèse à glaucophane et lawsonite sont semblables à ceux des Célèbes, des Coast Ranges, de Kantô-Sibugawa, de Corse et d'Ambin.

La genèse de la jadéite résulterait de la transformation albite → jadéite + quartz (en gouttelettes) sous de fortes pressions associées à des températures modérées. Un enfoncement temporaire à grande profondeur ne peut pas être envisagé. La carte de répartition alpine de la jadéite et des pyroxènes sodiques, et les altérations générales des cristaux de glaucophane, jadéite et lawsonite, indiquent qu'une large partie de l'arc alpin s'est trouvé d'abord dans des « conditions glaucophanitiques », ensuite dans des « conditions prasinitiques ».

Nanosized porphyrin-containing metal-organic frameworks (MOFs) attract considerable attention as solid-state photosensitizers for biological applications. In this study, we have for the first time synthesised and characterised phosphinate-based MOF nanoparticles, nanoICR-2 (Inorganic Chemistry Rez). We demonstrate that nanoICR-2 can be decorated with anionic 5,10,15,20-tetrakis(4-R-phosphinatophenyl)porphyrins (R = methyl, isopropyl, phenyl) by utilizing unsaturated metal sites on the nanoparticle surface. The use of these porphyrins allows for superior loading of the nanoparticles when compared with commonly used 5,10,15,20-tetrakis(4-carboxyphenyl)porphyrin. The nanoICR-2/porphyrin composites retain part of the free porphyrins photophysical properties, while the photodynamic efficacy is strongly affected by the R substituent at the porphyrin phosphinate groups. Thus, phosphinatophenylporphyrin with phenyl substituents has the strongest photodynamic efficacy due to the most efficient cellular uptake.
Adult Children’s Perspectives on Their Role in Their Parent’s Hearing Healthcare Processes
Authors: Heacock Raquel M. , Montano Joseph J. , Preminger Jill E.
Published: November 2018

Background:Communication partners play an important role in the hearing healthcare (HHC) process of the person with hearing impairment (HI). However, present research focuses mainly on the role of the spouse; the role of the adult child is often overlooked or understated.Purpose:The
aim of the study was to describe the role of the adult child in the HHC process of a parent with HI.Research Design:Using a qualitative study design, participants described their role in their parents’ HHC process and the impact of a parent’s HI on their relationship and
communication in individual semi-structured interviews.Study Sample:Twelve adult children of ten parents with HI participated; two sets of siblings were included to gain different perspectives on the HHC process within the same family.Data Collection and Analysis:Thematic analysis,
a qualitative method to explore participant’s perceptions and viewpoints, was used as the method of analysis.Results:The superordinate theme discussed most frequently by participants, communication management, was bolstered by three ideas or pillars: facilitating HHC, communication
strategies, and encouraging hearing aid use. Adult children saw themselves as advocates or supporters of their parent’s HHC by taking an ongoing and active role in promoting successful communication rather than a role in directing their parent’s HHC actions. Within each pillar
of communication management, participants’ perceptions and actions were modulated by the varying levels of effort and a desire to ask questions to better understand how to help their parent, which in turn influenced their awareness of the HI and HHC options, often resulting in the adult
child putting forth new effort.Conclusions:Whereas the patient journey is often presented to the patient as a linear process, the adult children instead viewed the process of communication management as an ongoing and continuous cycle. The audiologist should be encouraged to involve
adult children in the HHC process, as adult children play an important role in everyday communication management.
AutoAdaptive: A Noise Level‐Sensitive Beamformer for MED EL Cochlear Implant Patients
Authors: Dorman Michael F. , Natale Sarah Cook
Published: November 2018

Background:When cochlear implant (CI) listeners use a directional microphone or beamformer system to improve speech understanding in noise, the gain in understanding for speech presented from the front of the listener coexists with a decrease in speech understanding from the
back. One way to maximize the usefulness of these systems is to keep a microphone in the omnidirectional mode in low noise and then switch to directional mode in high noise.Purpose:The purpose of this experiment was to assess the levels of speech understanding in noise allowed by a
new signal processing algorithm for MED EL CIs, AutoAdaptive, which operates in the manner described previously.Research Design:Seven listeners fit with bilateral CIs were tested in a simulation of a crowded restaurant with speech presented from the front and from the back at three
noise levels, 45, 55, and 65 dB SPL.Data Collection and Analysis:The listeners were seated in the middle of an array of eight loudspeakers. Sentences from the AzBio sentence lists were presented from loudspeakers at 0 or 180° azimuth. Restaurant noise at 45, 55, and 65 dB SPL was
presented from all eight loudspeakers. The speech understanding scores (words correct) were subjected to a two-factor (speaker location and noise level), repeated measures, analysis of variance with posttests.Results:The analysis of variance showed a main effect for level and location
and a significant interaction. Posttests showed that speech understanding scores from front and back loudspeakers did not differ significantly at the 45- and 55-dB noise levels but did differ significantly at the 65-dB noise level—with increased scores for signals from the front and
decreased scores for signals from the back.Conclusions:The AutoAdaptive feature provides omnidirectional benefit at low noise levels, i.e., similar levels of speech understanding for talkers in front of, and in back of, a listener and beamformer benefit at higher noise levels, i.e.,
increased speech understanding for signals from in front. The automatic switching feature will be of value to the many patients who prefer not to manually switch programs on their CIs.
A RE-ASSESSMENT OF HOUSE PRICE INDICES: EVIDENCE FROM THE SPANISH MARKET
Authors: Paz Paloma Taltavull de la , McGreal Stanley
Published: November 2018

This paper using evidence from the Spanish housing market contributes significantly to the debate concerning the different results obtained from house price indices depending on the method used to build the index. Utilising a large database over the period 1994 to 2012, the paper constructs a time dummy hedonic index (HD) and an imputed hedonic index using a Laspeyres approach (HI), and compares the different effect on the price index evolution. The paper discusses control by quality changes and identifies those attributes experiencing structural changes over the analysis period, identified by the HI index but not by the HD index. Results indicate that changes in quality stem from socio-demographic conditions rather than changes to housing quality (other than size). The paper also shows that improvements in neighbourhood quality rather than change in a ‘typical house’ affects house price and argues that these considerations are important in both the method selected to calculate house price indices and the application of the methodology to estimate price changes.
EMPLOYEE SATISFACTION WITH THE PHYSICAL WORK ENVIRONMENT: THE IMPORTANCE OF A NEED BASED APPROACH
Authors: Budie Bart , Appel-Meulenbroek Rianne , Kemperman Astrid , Weijs-Perree Minou
Published: November 2018

Employee satisfaction is pivotal for companies as it enhances perceived productivity and organizational performance. Office concepts and their workspaces can affect employee satisfaction. However, these effects are still ambiguous, particularly regarding the activity-based concept. Therefore, in this study employee satisfaction with the work environment is investigated from a holistic approach. The effects of both personal characteristics and workspaces used by the employee on work environment satisfaction are described and measured, including mediating effects of the perceived importance of employee needs. Data was collected using an online questionnaire among 327 employees of 13 knowledge-based organizations. Path analysis was used to determine the direct and indirect effects of personal variables, environmental variables and perceived importance of needs on satisfaction. It demonstrated that both personal and environmental variables affect satisfaction, and that a considerable number of these effects are indirect through the perceived importance of needs. In particular, the effects of used workspaces were extensive.

We use Atacama Large Millimeter/submillimeter Array and Institute for Radio Astronomy in the Millimeter 30 m telescope data to investigate the relationship between the spectroscopically traced dense gas fraction and the cloud-scale (120 pc) molecular gas surface density in five nearby, star-forming galaxies. We estimate the dense gas mass fraction at 650 and 2800 pc scales using the ratio of HCN (1−0) to CO (1−0) emission. We then use high-resolution (120 pc) CO (2−1) maps to calculate the mass-weighted average molecular gas surface density within 650 or 2770 pc beam where the dense gas fraction is estimated. On average, the dense gas fraction correlates with the mass-weighted average molecular gas surface density. Thus, parts of a galaxy with higher mean cloud-scale gas surface density also appear to have a larger fraction of dense gas. The normalization and slope of the correlation do vary from galaxy to galaxy and with the size of the regions studied. This correlation is consistent with a scenario where the large-scale environment sets the gas volume density distribution, and this distribution manifests in both the cloud-scale surface density and the dense gas mass fraction.
Rise to fame: events, media activity and public interest in pangolins and pangolin trade, 2005–2016
Authors: Harrington Lauren A. , D'Cruze Neil , Macdonald David
Published: November 2018

Attention focused on pangolins (Pholidota) and the threats posed to their survival and welfare by international trade (for use in Chinese Traditional Medicine and the Asian wild meat market) has skyrocketed across all digital information platforms over the last decade. Previously obscure and often referred to as the ‘mammal you’ve never heard of’, pangolins are now widely recognised as an icon of the illegal wildlife trade. We document the events that led to the pangolins’ ‘rise to fame’, culminating in its Appendix I listing by CITES in September 2016 and a global commercial trade ban and explore temporal co-occurrence between events and peaks in media activity and public interest with the aim of identifying events (or types of events) that may have been influential in terms of awareness-raising. More broadly, our objective was to highlight lessons in public communication that might be applied to awareness campaigns for other lesser-known threatened species. We found no evidence that any particular type of event was more likely to generate a significant media/public response than any other, but peaks in public interest co-occurred with reports of pangolin seizures, highlighting the importance of news coverage of these incidents. Further, although neither editorial nor social media peaks were strongly correlated with the timing of events, they sometimes co-occurred with different events and each differed in their coverage of different types of events, suggesting that editorial and social media have independent and distinct roles to play in conservation communication. However, despite their iconic status, public interest in pangolins is still not equivalent to that directed at, for example, tigers, elephants or lions, so efforts need to be sustained. Finally, we note that, although attention can help to generate funds and influence policy, this alone will not be enough to achieve a favourable conservation status for pangolins – on-going and future work need to ensure that public enthusiasm for this species is translated into effective protection.

Published: November 2018

Cet article étudie la performance des fonds mutuels à la BRVM à travers trois indicateurs de performance ajustée au risque : le ratio de Sharpe modifié, le ratio d’information et le ratio de Treynor-Mazuy. L’étude a été effectuée sur un échantillon de 13 Fonds Communs de Placement (FCP) faisant partie des catégories obligations, actions et diversifiés et porte sur la période allant du 02 septembre 2013 au 16 décembre 2016. Nos résultats sont moins tranchés que dans la littérature : les fonds mutuels de la BRVM sont en moyenne plus performants que l’indice de référence. En plus les gestionnaires de fonds mutuels à la BRVM possèdent de réelles capacités en termes de sélectivité et d’anticipation du marché. De tels résultats justifient l’intérêt d’investir dans ces types de placement financiers. Le classement par catégorie indique que les fonds mutuels les plus performants sont les FCP actions suivis des FCP diversifiés, et les FCP obligations sont les moins performants. Cependant, la faiblesse de l’échantillon (13 sur 57 FCP que compte le marché), relativise la portée générale de ce travail.

Persistent primitive trigeminal artery associated with a cavernous carotid aneurysm. Case report and literature review.
Authors: Lam Jeremy Jia Hong , Mohamed Shah Mohammad Taufik bin , Chung Siok Li , Ho Chi Long
Published: November 2018

The persistent primitive trigeminal artery is the most common persistent carotid-vertebrobasilar anastomosis. Patients are usually asymptomatic and the persistent primitive trigeminal artery is commonly found incidentally on imaging. Rarely, they may present with symptoms of neurovascular conflict or cranial nerve compression syndromes as the artery may be intimately related to the cranial nerves. The basilar artery is often hypoplastic in this condition and blood supply to the posterior circulation is predominantly via the persistent primitive trigeminal artery. Recognizing the persistent primitive trigeminal artery is imperative as disease of the artery may result in ischemia of the posterior circulation. To date, there is no clear association between this artery and cerebral aneurysms. We present a rare case of a patient with a persistent primitive trigeminal artery and a concomitant cavernous carotid aneurysm together with a literature review.
La sociedad civil y las enfermedades raras
Authors: Serrano Mercedes
Published: November 2018

Las enfermedades poco frecuentes suelen ser las grandes olvidadas tanto de los sistemas sanitarios como de la investigación. Esto da lugar a que los pacientes y los familiares encuentren dificultades no solo para recibir una asistencia médica adecuada, sino también para conseguir un verdadero apoyo psicosocial. No obstante, se están produciendo cambios muy positivos, como son la creciente presencia del conjunto de las enfermedades raras en las políticas nacionales e internacionales, la evolución en el papel que adoptan los pacientes, los médicos y los investigadores y en sus relaciones mutuas, la creciente sensibilización e implicación social, las oportunidades crecientes de difusión y de sensibilización y la circunstancia favorable desde el punto de vista tecnológico y de comunicación. La complejidad de estos cambios y la responsabilidad que cada grupo de agentes implicados está asumiendo en este nuevo marco son asuntos controvertidos y están surgiendo cuestiones de índole ética.

The Importance of IT on Preventing Organizational Amnesia
Authors: Erben Gül Selin , Doğantemur Arda
Published: November 2018

The ratio of benefiting from company's own memory is one of the most important factors for a company's success. However, firms are not aware of their memory capacity or failure to protect. Therefore, the success of the company is delayed and or affected negatively. Because of organizations' natural tendency to forget, memory loss is evaluated as an inevitable consequence. Memory loss or organizational amnesia at the organizations is defined as restricting the ability to develop organizational learning or failure to create a value by using owned information of the company. Organizational amnesia in organizations shows itself in various forms such as repetitive losses of competencies and previously learned information because effectiveness decrease leads to repetition of the same mistakes. In this context, the aim of this chapter is to create an organization memory database known as a knowledge repository in order to minimize memory loss in the organization and to determine the information types which is being recorded in the database.
4SRS-SoaML Method for Deriving a Service-Oriented Architecture From Use Cases Within a SPEM Approach
Authors: Salgado Carlos , Machado Ricardo J. , Maciel Rita S. P.
Published: November 2018

The transformation of requirements specification into an architectural design has been a crucial endeavor for the information systems analysis and design community, with ever-new challenges to tackle. Despite the wide and diverse existing proposals, the lack of a common structure and use of different strategies makes it close to impossible to analyze or compare these approaches. Therefore, the use of model-based methods benefits from a detailed specification in order to support their analysis and evolution, also in comparison to other approaches. Following work on the derivation of a logical architecture from business-process use-cases requirements in a service-oriented approach, the authors propose a detailed specification, within a SPEM approach, of a transformation method, which they further analyze and refurbish in order to meet current and future challenges.
Human Health Risk Assessment via Amalgamation of Probability and Fuzzy Numbers
Authors: Dutta Palash
Published: November 2018

This chapter presents an approach to combine probability distributions with imprecise (fuzzy numbers) parameters (mean and standard deviation) as well as fuzzy numbers (FNs) of various types and shapes within the same framework. The amalgamation of probability distribution and fuzzy numbers are done by generating three algorithms. Human health risk assessment is performed through the proposed algorithms. It is found that the chapter provides an exertion to perform human health risk assessment in a specific manner that has more efficacies because of its capacity to exemplify uncertainties of risk assessment model in its own fashion. It affords assistance to scientists, environmentalists, and experts to perform human health risk assessment providing better efficiency to the output.
Clustering Techniques
Authors: Kumar Harendra
Published: November 2018

Clustering is a process of grouping a set of data points in such a way that data points in the same group (called cluster) are more similar to each other than to data points lying in other groups (clusters). Clustering is a main task of exploratory data mining, and it has been widely used in many areas such as pattern recognition, image analysis, machine learning, bioinformatics, information retrieval, and so on. Clusters are always identified by similarity measures. These similarity measures include intensity, distance, and connectivity. Based on the applications of the data, different similarity measures may be chosen. The purpose of this chapter is to produce an overview of much (certainly not all) of clustering algorithms. The chapter covers valuable surveys, the types of clusters, and methods used for constructing the clusters.
An Integral View of Mindfulness Practices and the Perception of Challenge Within a High School Setting
Authors: Daniel Anne
Published: November 2018

The purpose of this chapter was to examine how mindfulness-based strategies are taught within four different classroom settings in a large urban high school and how they impact students' perceptions of challenge. Two different approaches toward mindfulness training were represented in the four classrooms: the first derived from an explicit, outcomes-based approach within a Yoga class setting with a focus on awareness of personal experience; the other was embedded and implicitly connected to the subject discipline of natural science with a focus on situated being. Integral methodological pluralism (IMP) was used to gather data from multiple viewpoints: phenomenological interviews, structural analysis of language frequency and comparisons, ethnographic observations, and hermeneutic interviews. Integral theory was used to analyze the data and identify the individual and cultural themes. Systemic influences are discussed in connection with these findings, and implications for implementation of mindfulness in relation to perception of challenge are explored.
Promising Futures
Authors: Norris Roy A.
Published: November 2018

Teachers spend their working days preparing young people for the times to come. Teachers also imagine a wide variety of ideas about possible, probable, and preferable futures. This chapter explores how teachers feel and think about the potential futures for themselves and their students, and how teacher perceptions of futures inform their teaching practices. The study sets integral theory as the basis for the methodological pluralism and analytical blending which are sustained throughout this trans-disciplinary study as a whole. The findings show that although high school teachers envision many possible futures, they are most likely to trust shorter term empiric predictions, and they rarely think about futures more than a few years away. Learning more about how often, how deeply, and how optimistically teachers envision possible futures matters because teachers are educating the people who will become adults in all versions of the near futures.
Creating a Culture of Inclusion in Pre-Kindergarten
Authors: Prytuluk Natalie Anne
Published: November 2018

The purpose of this study was to understand how beliefs, understandings, and pedagogical practices of early childhood educators affect, and are affected by, their relationships with children, classroom team members, parents, and colleagues, as they create an inclusive culture in a pre-kindergarten classroom. To explore this research problem from multiple perspectives, integral theory was selected as the conceptual framework, and a multi-methods exploratory sequential design was employed using integral methodological pluralism. Data about educational experiences, culture, behaviors, and systems, were collected from five early childhood educators in pre-kindergarten classrooms in four urban schools, followed by a questionnaire of classroom practices, document analysis, and a focus group. Findings revealed that important factors for creating an inclusive classroom culture included: early childhood educators' positive beliefs toward inclusion; a social constructivist theoretical perspective; and the ability to build strong relationships with children, parents, and colleagues.

Sa'i Smart Library Learning Lab
Authors: Almarzooqi Sara Saleh
Published: November 2018

Nationally, schools are unable to cope with the increasing demands imposed upon the teachers and students as the learning systems have not changed. On the other hand, there is an increasing need for librarians to assist curriculum needs in schools and the national education agenda of UAE, of having human talents who are knowledge creators, have sufficient 21st century skills, lifelong learning habits, positive beliefs and behaviors, and knowledge and skills related to STREAM as well as a holistic personality. The role of public libraries could be extended further to work closely with schools in a systemic way that enables both entities to reach another milestone. Schools can establish another supportive educational after-school system to empower teachers and students. A more extensive and rigorous as well as controlled system that all stakeholders, teachers, and parents could share to provide the opportunity for students to be effective knowledge-contributors is planned and shared in this chapter.

Authors: Mwashita Weston , Odhiambo Marcel Ohanga
Published: November 2018

The snowballing of many different electronic gadgets connected to different networks and to the internet is a clear indication that the much-anticipated internet of things (IoT) is fast becoming a reality. It is generally agreed that the next generation mobile networks should offer wireless connection to anything and anyone with a proper enabling device at any time leading to the full realization of IoT. Device-to device (D2D) communication is one technology that the research community believes will aid the implementation of the next generation of mobile networks, specifically 5G. Full roll out of D2D is however being impeded by the resulting interference. This chapter looks at the state-of-the-art research works on interference management technologies proposed for device-to-device communications. A comprehensive analysis of the proposed schemes is given and open challenges and issues that need to be considered by researchers in D2D communication for it to become a key enabler for 5G technology are highlighted and recommendations provided.
