A dataset of molluscan fauna sampled in river estuaries of medium and small size river in Kyushu island, Japan
Authors: Itsukushima Rei , Yoshikawa Hiroaki , Morita Kai
Published: July 2018

Many studies have evaluated the ecological integrity of large-scale estuaries of continental rivers using biotic indicators such as fish, phytoplankton and benthic communities. However, few studies have focused on the river estuaries of small and medium rivers. Molluscan fauna data in large estuaries or in the estuaries of large rivers have been collected by the The National Census on River Environments (conducted by the Ministry of Land, Infrastructure, Transport and Tourism) or National Survey on the Natural Environment (conducted by the Ministry of Environment). On the other hand, molluscan fauna of small and medium rivers are managed by local governments and have rarely been investigated.

This paper provides basic information on the molluscan fauna of 70 rivers in Kyushu, Japan, collected with the aim of conserving estuaries of small and medium rivers. In total, 37 families, 82 species and 21,827 individuals were collected. The data are all accessible from the document “A dataset of shellfish fauna sampled in estuaries of medium and small rivers in Kyushu, Japan (http://ipt.pensoft.net/resource.do?r=shellfishes_in_kyushu)”. According to the Red Data Book published by the Japanese Ministry of Environment in 2018, 3 species were determined as Critically endangered and Endangered, 6 species were determined as Vulnerable and 13 species were determined as Near Threatened. The proportions of individuals classified as Critically endangered and Endangered from the total number of individuals were extremely low, but the proportions of Near Threatened individuals were high. Our results indicate that the risk of molluscan extinction in small- and medium-sized river estuaries in Kyushu is high and that immediate conservation is necessary.

Authors: Akkari Nesrine , Ganske Anne-Sarah
Published: July 2018

Recent collecting on the island of La Palma has yielded two new records, Lithobius (Monotarsobius) crassipesoides and Lithobius (Lithobius) melanops, the former also being new to the Canary Islands and is recorded for the first time after its recent description. We additionally provide species records for the lithobiomorph species of the island, with new locality data and a distribution map based on recent and literature records. We update the checklist of the lithobiomorph species of the Canaries and document all the newly collected species.
Increase of banks’ credit risks forecasting power by the usage of the set of alternative models
Authors: Karminsky Alexander M. , Khromova Ella
Published: July 2018

The paper is aimed at comparing the divergence of existing credit risk models and creating a synergic model with superior forecasting power based on a rating model and probability of default model of Russian banks. The paper demonstrates that rating models, if applied alone, tend to overestimate an instability of a bank, whereas probability of default models give underestimated results. As a result of the assigning of optimal weights and monotonic transformations to these models, the new synergic model of banks’ credit risks with higher forecasting power (predicted 44% of precise estimates) was obtained.
Faire partie de la bande
Authors: Coquard Benoît
Published: July 2018

Ce texte fait l’hypothèse qu’en milieu populaire rural, l’appartenance à un groupe d’amis vient pallier l’obsolescence d’anciennes instances de socialisation de genre et de classe. Pour les jeunes hommes de classes populaires enquêtés, les « bandes de potes » opèrent désormais comme des cadres de production d’une masculinité légitime. Dans un contexte d’homogénéité sociale, la masculinité ne s’exprime pas tant dans des discours que dans le fait « d’en être », de montrer son amitié avec d’autres hommes ayant eux-mêmes bonne réputation et appartenant à un groupe à la fois sélectif et solidaire. L’article montre que l’appartenance amicale est ainsi un élément essentiel du statut social de ces hommes, en préservant leur réputation et en leur inculquant des façons d’être valorisées dans ce milieu.
Le don au cœur de la construction d’une GRH partagée en PME
Authors: Adla Ludivine , Gallego-Roquelaure Virginie
Published: July 2018

Dans la continuité des travaux de Psychogios et al. (2016), cet article propose une nouvelle forme de GRH construite conjointement par le dirigeant et les salariés en contexte de PME. Notre analyse théorique intègre la littérature sur la GRH en PME et la théorie maussienne du don/contre-don. Une étude longitudinale et rétrospective menée auprès d’une PME du secteur de l’Économie Sociale et Solidaire aboutit à la construction d’une modélisation processuelle d’une GRH partagée révélant les étapes du don : le don initial du dirigeant, l’adonnement des salariés et le contre-don attendu.
Les arts industriels à l’école et au musée. L’École nationale de Roubaix et ses références au xix e siècle
Authors: Lembré Stéphane
Published: July 2018

L’ouverture en 1889 à Roubaix de l’imposante École nationale des arts industriels s’inscrit à la rencontre de la volonté locale de promouvoir la formation technique pour l’industrie textile par une institution supérieure, de l’ambition des républicains de rivaliser sur le terrain économique avec des nations rivales, et enfin de références internationales en matière de formation à l’art et à l’industrie. L’établissement réunit ainsi deux dimensions : l’enseignement, par des cours du jour et du soir, et l’exposi tion, grâce à plusieurs musées intégrés dans les locaux et accessibles aux industriels. Si les musées commerciaux et industriels sont en plein essor à la fin du xix e siècle, il faut aussi situer l’organisation roubaisienne par rapport au développement des musées scolaires.
Le désengagement de l'État providence
Authors: Bernier Nicole F.
Published: July 2018

Plusieurs raisons militent en faveur d'une étude du processus de désengagement de l'État dans le domaine de la protection sociale. Certains voudront mieux connaître les fondements et l'organisation du filet de sécurité sociale au Canada. D'autres voudront savoir aussi en quoi a consisté sa restructuration profonde à partir de 1975. D'autres, enfin, s'intéresseront au processus de désengagement en tant que tel ou encore aux stratégies politiques que le gouvernement fédéral a mises en place pendant une vingtaine d'années pour restructurer la sécurité du revenu au moindre coût politique possible.Cet ouvrage poursuit trois grands objectifs. D'abord, il vise à analyser le processus et les formes de désengagement du gouvernement canadien dans le domaine de la sécurité du revenu entre 1975 et 1995. Pour ce faire, il examine les changements qui se sont produits dans quatre grands programmes fédéraux : pensions de vieillesse, assurance-chômage, Régime d'assistance publique du Canada et prestations financières pour enfants. Ensuite, il compare les approches et stratégies que le gouvernement fédéral a poursuivies au cours de cette période pour se désengager de certaines obligations financières envers les citoyens. Enfin, il établit des distinctions importantes entre les facteurs associés à l'expansion de l'État providence canadien (1950 à 1974) et ceux associés au désengagement (depuis 1975).À Ajab, Isabelle et Pierre.
Les mouvements sociaux
Authors: Farro Antimo L.
Published: July 2018

Ce livre propose un modèle explicatif des mouvements sociaux contemporains. Il réexamine dans cette optique les classiques de la sociologie, puis il passe en revue les théories plus récentes de la mobilisation des ressources et de la sociologie de l'action. Il montre comment ces mouvements naissent de la résistance d'individus et de groupes aux acteurs dirigeants, à ceux qui contrôlent les flux financiers et la fabrication de l'information. L'enjeu pour ces mouvements ne se situe donc plus sur le terrain de la lutte des classes, mais tient plutôt à la détermination des symboles et des codes culturels des divers secteurs de la vie sociale, depuis la santé jusqu'à l'éducation, en passant par les médias et l'environnement.
Décision de transfert Dublin anticipée : la CJUE souligne le détournement de procédure des préfectures françaises
Authors: Guérin Antoine
Published: July 2018

Pour satisfaire à l’exigence d’efficacité imposée par la réforme de la politique d’asile française, les préfectures avaient pris pour habitude d’adopter, à l’encontre des demandeurs d’asile « dublinés » présentant un « risque non négligeable de fuite », des notifications de transfert « anticipées ». Autrement dit, avant même que l’État membre auquel elles adressaient leur requête de prise ou de reprise en charge n’ait le temps d’y répondre, elles adoptaient une décision de transfert de manière unilatérale, et ce dans un seul but : pouvoir placer plus rapidement en rétention le demandeur d’asile en question. Si l’illégalité de cette pratique saute aux yeux, elle a divisé les juridictions administratives françaises jusqu’à ce que l’une d’entre elles décide de requérir un arbitrage auprès de la Cour de justice de l’Union européenne, dont l’issue n’est pas décevante. Elle dissèque réellement la pratique des préfectures françaises pour d’abord montrer comment elles détournent gravement le règlement Dublin III lui-même. Elle aborde ensuite le risque important d’altération qu’elle fait peser sur la politique d’asile européenne de manière générale. Preuve que les préfectures n’ignoraient pas l’illégalité de leur pratique, les mises en garde de la Cour se retrouvent privées d’une quelconque utilité à l’aune du changement, entretemps, de la législation française.
Demande d’asile au motif de l’orientation sexuelle : la CJUE fait un tout petit pas… mais dans la bonne direction
Authors: Bongiovanni Alexandre
Published: July 2018

C’est grâce à l’impulsion du tribunal administratif et du travail hongrois que la Cour de justice de l’Union européenne a été amenée, le 25 janvier 2018, à se prononcer sur la question de l’examen de la demande de protection internationale du fait de persécutions au motif de l’orientation sexuelle du demandeur. Si de nombreuses affaires ont déjà été rendues en la matière, cette affaire se distingue par l’attention particulière accordée par la Cour aux tests projectifs qui permettent, dans une certaine mesure, d’évaluer la personnalité du sujet à travers ses réactions à des images ou des photographies. En effet, la Cour estime que le recours à ces tests constitue une atteinte disproportionnée et non consentie au droit à la vie privée du demandeur d’asile. Ainsi, la Cour interdit aux autorités nationales l’emploi de tels tests. Cela constitue en soi une avancée qui mérite d’être saluée. Cependant, la Cour ne manque pas de rappeler que les autorités nationales peuvent interroger la crédibilité des allégations du demandeur quant à son orientation sexuelle. En cela, la décision de la Cour reste pour le moins contestable.
L’architettura dei Minori nella custodia napoletana: ricezione e circolazione di motivi oltremontani da San Lorenzo Maggiore in Napoli a San Francesco di Nola (xiii-xiv secc.)
Authors: Di Cerbo Cristiana
Published: July 2018

Si au xiiie et xive siècle, dans le Sud de l’Italie, les angevins embauchent souvent des architectes et bâtisseurs français, le système architectural ad modum Franciae ne fut jamais adopté dans ses formules authentiques, mais toujours combiné avec les traditions locales. Cette pratique du bâti donne naissance à un lexique formel hybride, autrement dit à un Gothique de compromis. Cette investigation consacrée à l’architecture franciscaine de la « custodia napoletana » permet toutefois de constater qu’une telle réception se concrétise uniquement dans l’invention et la combinaison des nouveautés techniques et formelles et de leurs caractéristiques stylistiques, mais aussi dans la diffusion d’un canon architectural au fort accent identitaire, partagé à la fois par la monarchie et la baronnie locale.

Privacy and Security in Data-Driven Urban Mobility
Authors: Akerkar Rajendra
Published: July 2018

A wide range of smart mobility technologies are being deployed within urban environment. These technologies generate huge quantities of data, much of them in real-time and at a highly granular scale. Such data about mobility, transport, and citizens can be put to many beneficial uses and, if shared, for uses beyond the system and purposes for which they were generated. Jointly, these data create the evidence base to run mobility services more efficiently, effectively, and sustainably. However, generating, processing, analyzing, sharing, and storing vast amounts of actionable data also raises several concerns and challenges. For example, data privacy, data protection, and data security issues arise from the creation of smart mobility. This chapter highlights the various privacy and security concerns and harms related to the deployment and use of smart mobility technologies and initiatives, and makes suggestions for addressing apprehensions about and harms arising from data privacy, protection, and security issues.

Teacher Socialization and Teacher Isolation
Authors: Öntaş Turgay
Published: July 2018

This study addresses teacher socialization and isolation primarily within the context of induction to the profession, workplace learning, and informal learning. Since the content of the subject is covered by fields of sociology, pedagogy, psychology, management, and organization, the concepts of induction to the profession and workplace learning were used to establish the basis for teacher socialization and isolation. How the teacher socializes influences the quality of education because socialization influences how the teacher performs his job. Increased interest in teacher training results in increased teacher quality, thereby increasing educational success. Increased interest in teacher training is accompanied by pursuit for quality in teacher training systems. Increasing teacher quality is not only related to training the teacher in preservice programs. Considering the fact that there are teachers who had received preservice training, yet started the profession prematurely, in-service learning processes are important in efforts to ensure teacher quality as well.

R&D is increasingly becoming globalized and implemented on a collaborative basis. It leads to the need for search of partners, resources, and ideas from outside the company. Currently authorities all over the world have a tendency to develop regional economic systems into regional innovation ecosystems. It in turn creates new challengers to the innovation intermediaries. The chapter is devoted to the search for ways to unite the innovation ecosystem concept with the theory of innovation intermediation, emphasizing specific types of innovation intermediation and fundamental mechanisms thereof, supporting incentives and the role in the innovation ecosystem. Hence, there needs to be a shift to the network organization of infrastructure that ensures a high level of participants' cooperation. Moreover, end-users of innovations are being considered as key actors in the innovation processes. The research results may be implemented into managerial practices in order to improve the competitiveness of regional economic systems.

Impacts of the Tourist Activity and Citizens' Evaluation About the Necessity for Resting Periods
Authors: Martin Jose Maria
Published: July 2018

Tourism's interactions with local communities and natural environments originate economic, social, and environmental impacts both positive and negative. The local community's assessment of these impacts is key to guarantee their support for tourism development since the planning process is subject to their opinion. Tourism seasonality can intensify these effects due to the influx of tourists during peak periods and generate periods of rest and recovery during the off-peak season. In this research, the locals' opinions on the need for a period of seasonal rest is studied, even if this period interrupts the economic activity linked to tourism. Using a group of Spanish touristic destinations shows that the residents in coastal destinations prefer the annual continuity of the activity and that they are much more critical of the environmental effects than social ones. On the contrary, the inhabitants of urban and rural destinations would rather enjoy resting periods.
Branding Porto
Authors: Rodrigues Clarinda
Published: July 2018

Departing from the Porto brand case study, this chapter discusses the concept of destination brand identity from the supply-side perspective. Consequently, it proposes an authentic-based approach to place identity theory, in which destination authenticity is pointed out as a key driver to create a strong place brand identity. Moreover, it is suggested that destination managers should follow an eight-step approach to branding a destination. This dynamic view of place identity, which is supported by a continuous co-creation process involving local and external stakeholders, allows destination brand managers to mirror and reinforce the destination authenticity.

Authors: Ali Md Shaheb , Miah Shah J.
Published: July 2018

Business intelligence (BI) has proliferated due to its growing application for business decision support. Research on organizational factors may offer significant use in BI implementation. However, a limited number of studies focus on organizational factors for revealing adverse impacts on effective decision support. The aim of this theoretical study is to conduct a literature analysis to identify organizational factors relevant to BI implementation. Through a systematic literature review, a qualitative content analysis on 49 relevant sample articles for generating themes inductively is adopted to reveal organizational factors. Findings suggest two contexts: information management that integrates factors such as technological capability and personnel capability and organizational context that integrates factors such as organizational capability, managerial decision, and organizational culture for facilitating embedding information management capability for BI implementation in businesses. It is hoped that these contextual understanding can be useful for further BI implementations.

Authors: Lu Xiaoling , Rai Bharatendra , Zhong Yan , Li Yuzhu
Published: July 2018

Prediction of app usage and location of smartphone users is an interesting problem and active area of research. Several smartphone sensors such as GPS, accelerometer, gyroscope, microphone, camera and Bluetooth make it easier to capture user behavior data and use it for appropriate analysis. However, differences in user behavior and increasing number of apps have made such prediction a challenging problem. In this article, a prediction approach that takes smartphone user behavior into consideration is proposed. The proposed approach is illustrated using data from over 30000 users from a leading IT company in China by first converting data in to recency, frequency, and monetary variables and then performing cluster analysis to capture user behavior. Prediction models are then developed for each cluster using a training dataset and their performance is assessed using a test dataset. The study involves ten different categories of apps and four different regions in Beijing. The proposed app usage prediction and next location prediction approach has provided interesting results.
Privacy-Preserving Orchestrated Web Service Composition with Untrusted Brokers
Authors: Khabou Imen , Rouached Mohsen , Viejo Alexandre , Sánchez David
Published: July 2018

This article describes how by using web service composition to model different business processes is a usual tendency in the industry. More specifically, web service composition enables to separate a certain process in different activities that must be executed following a certain order. Each activity has its own set of inputs and outputs and is executed by a certain web service hosted by a service provider which can be completely independent. Among all the applications in which web service composition may be applied, this article focuses on a cloud-based scenario in which a business wishes to outsource the execution of a certain complex service in exchange for some economical compensation. It is for this reason, among the different composition approaches that exist in the literature, this article focuses on the orchestrated one, in which a broker coordinates the composition. One of the main issues of orchestrated systems is the fact that the broker receives and learns all the input data needed to perform the requested complex service. This behavior may represent a serious privacy problem depending on the nature of the business process to be executed. In this article, a new privacy-preserving orchestrated Web service composition system based on a symmetric searchable encryption primitive is proposed. The main target of this new scheme is to protect the privacy of the business that wish to outsource their operations using a cloud-based solution in which the broker is honest but curious, this is, this entity tries to analyze data and message flows in order to learn all the possible sensitive information from the rest of participants in the system.
Impact of Entrepreneur's Environmental Attitudes on Corporate Environmental Responsibility
Authors: Chandna Vallari
Published: July 2018

The impact of personal characteristics, beliefs, values and attitudes of the entrepreneur on firm's culture and business practices, is substantive. These aspects of the founder coupled with the institutional environment of the firm, affect the investment, efforts and involvement of the firm in a multitude of activities. With regard to activities that impact the natural environment, this paper argues that the environmental attitudes of entrepreneurs have a strong influence on the corporate environmental responsibility (CER) of the firm that are in turn moderated by the need for legitimacy by new entrepreneurial firms. The role of imprinting is examined to understand how founders' attitudes impact their firm's CER activities. A further contribution is the creation of a taxonomy of sub-categories of CER activities that illustrate the level of engagement of the firm.
Green Growth Intervention on Employment Generation in India
Authors: Goswami Anandajit , Chaudhury Saswata
Published: July 2018

This article highlights the possible impacts of green growth strategies and interventions on skilled and unskilled employment generation in India. Additionally, it indicates how income generation from selected green growth-related potential interventions can have a ripple effect on selected development indicators, like literacy rates, infant mortality rates, poverty. Job creation might translate to an economic gain for households of different income class across rural and urban India both in the short and long-term. This economic gain can thereafter reduce the level of inter-household and intra-household inter-temporal inequality levels with complementary and effective wealth distribution policies. In the long run, this reduction in the inequality level can create a positive impact on the social sustainability.

Published: July 2018

This study introduces a sucrose acetate isobutyrate (SAIB) as an additive of magnetorheological elastomers (MREs) to be added in silicone rubber matrix and carbonyl iron particles (CIPs) as their filler. The CIPs were fixed at 60 wt% and two types of MREs sample were fabricated which are isotropic and anisotropic. Rheological properties related to shear storage modulus were measured using a rheometer (MCR 302, Anton Paar). The experimental results demonstrated that the magnetorheological (MR) effect of anisotropic MREs-based Silicone/SAIB was 126 % as compared to isotropic MREs-based Silicone/SAIB, 64%. The fabricated MREs samples were frequency and strain dependent. The relative MR effect for both samples showed decreasing trend with the increment of strain amplitude and excitation frequency.

Authors: Marzuki Ahmad , Yunianto Mohtar , Riyatun  , Purwanto Hery
Published: July 2018

Absorption spectra of different composition of tellurite glasses were analyzed in order to estimate their lasing properties. Composition of the investigated tellurite glasses are: 55TeO2-(43-x)ZnO-2Bi2O3-xEr2O3(x = 0.5, 1.0, 1.5, 2.0, 2.5, 3.0 mol%). Glasses absorption spectra and density were measured at room temperature using UV-VIS-NIR Spectrophotometer and pycnometer, respectively; while their refractive index were measured by implying Brewster’s angle method. Lasing performance of glasses were then analyzed using Judd-Ofelt theory in order to obtain line strength (S), Judd-Ofelt parameters (Ωt, t = 1, 2, 3), and radiative life-times (τ). It is seen that incorporating Er3+ions of up to 2.5 mol% resulted in decreasing the radiative lifetime of electrons sitting at4I11/2. From Judd-Ofelt parameters analysis it can be concluded that these tellurite glasses tend to have the covalence nature of Er-O bond and thus represents the asymmetry around the Er3+ions site.

Authors: Yongvanich Niti , Chanthanan Chanakan , Ruennarong Nattanit , Suwanna Natthaya
Published: July 2018

This study examined the chemical stability of malayaite pigments in ceramic glazes containing high amounts of zinc oxide (ZnO). The calcined pigments were embedded in a molten glaze which is basically corrosive glass. Within the glaze, ZnO has been known among potters to be undesirable as some pigments are not stable in glazes containing ZnO. The synthesized pigments’ particle size ranges from 4 to 18 μm without dominant preferential orientation. Their colors were in the red and yellow tones. Chemical stability between the pigments and glazes was tested using X-ray Diffraction (XRD). Slight changes were observed. Increasing amounts of ZnO resulted in an interfacial layer of approximately 50 μm between the crystalline pigment and surrounding amorphous glaze. The a color parameters gradually decreased while the b parameters switched to a negative value. The resulting glazes evolved from maroon to pale violet. The correlation between color and microstructural alterations was discussed.

Published: July 2018

In this research, the influence of zinc oxide (ZnO) on the phase compositions and crystalline structure and microstructure of cement composite was studied. ZnO powder (0.5-1 wt% of cement) was used as an additive material. The Portland cement and ZnO powder were blended and mixed with water at the ratio constant (W/C) of 0.4. Then, the paste was cast into the molded for 24 hours. After these periods, the samples were dried at temperature 50°C for 24 hours. Those of samples were analyzed of crystalline structure and phase compositions by using X-ray diffraction technique (XRD). Microstructure analysis by using field emission scanning electron microscopy (SEM). It was found that the XRD spectra showed phases of calcium hydroxide (CH) and calcium silicate hydrated (CS), which were hydration products of cementitious material. Moreover, phase of zinc hydroxide (Zn(OH)2) is detected. Zn(OH)2have affected on the retardation of hydration reaction (more than 48 h). Zn(OH)2phase was formed on the surface of anhydrous tricalcium silicate (C3S) main compound in cement. The intensity of un-hydration products (C3S and C2S) increased with increasing content of ZnO nanoparticle in cement composites.

Authors: Ahmad Tagrid Younes , Al Houri Hasan Nabil , Al Houri Abdullah Nabil , Ahmad Nagham Younes
Published: July 2018

Orbital rhabdomyosarcoma (RMS) is a highly malignant tumor that originates mainly from mesenchymal tissue. It is considered a rare childhood malignancy; therefore, presentation in adulthood is scarce. In this case report, a 36-year-old male patient presented with a rapidly progressive RMS of the left orbit. The patient was treated in a different institution with radiochemotherapy with good response. However, relapse occurred after 2 months of completing the course, as rapid growing proptosis. Computed tomography scan revealed a lesion in the left orbit with invasion of the left ethmoid cells and the left maxillary sinus. Exenteration of the left orbit with the left partial maxillectomy and ethmoidectomy was performed. RMS is a highly aggressive malignancy that should be considered in any orbital mass that progresses rapidly. Surgery should be the first line in treatment. Delay in diagnosis and inappropriate treatment negatively affects the outcome.
Evaluating the efficacy of best practice alerts to improve Clostridium difficile early detection in hospital settings: A 6-month interim analysis of the 2-year prospective study
Authors: Kaako Ahmad
Published: July 2018

Introduction: Clostridium difficile infection (CDI) is a leading cause of hospital-associated gastrointestinal illness with high burden on the health-care system. Design: Observational, retrospective, prospective, pre- and post-intervention study on the incidence and prevalence rates of CDIs. The primary outcome is the healthcare-onset CDIs (HO-CDIs) incidence rate and proportion. Methods: Best practice alerts (BPAs) for CDI were developed in electronic medical records and released on July 13, 2016. When high-risk patients for CDI are identified, BPAs are triggered requiring nurses to order contact isolation and stool studies followed by other subsequent BPAs encouraging providers to de-escalate antibiotics and order probiotics. Data on admission count, patient-days, CDIs categories prevalence, and incidence rates were collected for the 24-month preintervention and will be collected for the 24-month postintervention period. Results: An interim analysis comparing the data from the first 6-month postintervention period with the average 6-month data of the preintervention period showed that short-term BPAs use is associated with significant increase in the overall CDI infection rate (71.47 vs. 38.38, P < 0.0001), incidence rate (53.81 vs. 28.76, P < 0.0001), overall prevalence rate (1.86 vs. 1.32, P = 0.001), and admission prevalence rate (1.10 vs. 0.70, P < 0.0001). Despite the observed overall shift from HO toward CO; no statistically significant difference in the HO-CDI event number and proportion was detected (28 [21.4%] vs. 22 [29.1%], P = 0.094). Conclusion: Short-term BPAs use is associated with significant increase in the overall CDI incidence and prevalence along with a non-statistically significant decline in HO-CDI proportion. Final analysis with full sample size is essential to provide a better picture about the long-term effect.

Процедуры проверки значений параметров $CVV$ и $PVV$ являются двумя важными механизмами обеспечения безопасности платежных систем. В работе с использованием аппарата теории доказуемой стойкости показано, что безопасность таких процедур существенным образом зависит от близости распределения наборов десятичных чисел, получающихся в результате процедуры децимализации, к равновероятному распределению. Показано, что используемая в современных платежных системах (например, в системе VISA) двухэтапная процедура децимализации приводит к существенным статистическим отклонениям, поэтому ее использование в платежной системе МИР не рекомендуется. Предлагается альтернативная процедура, обладающая лучшими характеристиками.

Использование корреляционно-иммунных функций в криптографическом примитиве может обеспечить его стойкость относительно ряда методов определения ключа. В настоящее время разработка криптографического примитива требует построения корреляционно-имунных функций от довольно большого количества переменных. В работе предлагается метод, основанный на использовании минимальных корреляционно-иммунных функций и комбинирующий два базовых подхода к решению указанной проблемы: итеративный метод и метод направленного поиска. Функции, получающиеся с помощью предложенного метода, не имеют явных структурных характеристик, которые можно было бы использовать для их отличения от случайных функций. Первый этап метода — просто реализуемая итеративная процедура, позволяющая построить множество функций специального вида, зависящих от заданного числа переменных. На втором этапе из построенных функций с помощью процедуры поиска строятся функции с заданными криптографическими характеристиками. В работе описано сведение задачи построения устойчивых функций заданного порядка к задаче решения системы псевдобулевых уравнений. Исследуется вопрос об использовании модификации предложенного метода для улучшения криптографических характеристик известных «хороших» функций с помощью малых изменений. Приводятся примеры применения разработанных методов.

Abstract. This paper presents a general approach to quantify the absorption model uncertainty due to uncertainty in underlying spectroscopic parameters. The approach is applied to radiative transfer calculations in the 20–60 GHz range, which is commonly exploited for atmospheric sounding by microwave radiometer (MWR). The approach however is not limited to any frequency range, observing geometry, or particular instrument. In the considered frequency range, relevant uncertainties come from water vapor and oxygen spectroscopic parameters. The uncertainty of the following parameters is found to dominate: (for water vapor) self and foreign continuum absorption coefficients, line broadening by dry air, line intensity, temperature-dependence exponent for foreign continuum absorption, and line shift-to-broadening ratio; (for oxygen) line intensity, line broadening by dry air, line mixing, temperature-dependence exponent for broadening, zero-frequency line broadening in air, temperature-dependence coefficient for line mixing. The full uncertainty covariance matrix is then computed for the set of spectroscopic parameters with significant impact. The impact of the spectroscopic parameter uncertainty covariance matrix on simulated downwelling microwave brightness temperatures (TB) in the 20–60 GHz range is calculated for six atmospheric climatology conditions. The uncertainty contribution to simulated TB ranges from 0.30 K (sub-Arctic winter) to 0.92 K (tropical) at 22.2 GHz, and from 2.73 K (tropical) to 3.31 K (sub-Arctic winter) at 52.28 GHz. The uncertainty contribution is nearly zero at 55–60 GHz frequencies. Finally, the impact of spectroscopic parameter uncertainty on ground-based MWR retrievals of temperature and humidity profiles is discussed.
Inter-channel uniformity of a microwave sounder in space

Abstract. We analyzed intrusions of the Moon in the deep space view of the Advanced
Microwave Sounding Unit-B on the NOAA-16 satellite and found no significant
discrepancies in the signals from the different sounding channels between
2001 and 2008. However, earlier investigations had detected biases of up to
10 K, by using simultaneous nadir overpasses of NOAA-16 with other satellites.
These discrepancies in the observations of Earth scenes cannot be due to
non-linearity of the receiver or contamination of the deep space view without
affecting the signal from the Moon as well. As neither major anomalies of the
on-board calibration target nor the local oscillator were present,
we consider radio frequency interference in combination with a strongly
decreasing gain the most obvious reason for the degrading photometric
stability. By means of the chosen example we demonstrate the usefulness of
the Moon for investigations of the performance of microwave sounders in
flight.

Abstract. There is an increasing amount of open Earth observation (EO) data available, offering solutions to map, assess and monitor natural resources and to obtain answers to global and local societal challenges. With the help of free and open source software (FOSS) and open access cloud computing resources, the remote sensing community can take the full advantage of these vast geospatial data repositories. To empower developing societies, support should be given to higher education institutions (HEIs) to train professionals in using the open data, software and tools. In this paper, we describe a participatory mapping methodology, which utilizes open source software Open Foris and QGIS, various open Earth observation data catalogues, and computing capacity of the free Google Earth Engine cloud platform. Using this methodology, we arranged a collaborative data collection event, Mapathon, in Tanzania, followed by a training of the related FOSS tools for HEIs’ teaching staff. We collected feedback from the Mapathon participants about their learning experiences and from teachers about the usability of the methodology in remote sensing training in Tanzania. Based on our experiences and the received feedback, using a participatory mapping campaign as a training method can offer effective learning about environmental remote sensing through a real-world example, as well as networking and knowledge sharing possibilities for the participating group.

Abstract. The study is to understand individual presence and movement in Friuli Venezia Giulia region. It is important for tourism planning, hazard management, business marketing, implementing government lifetime policies and benefit. The aim of this study is achieved by advanced web 2.0 applications. We need real time and geo-located data to monitor the inflow of tourist and to come up with effective promoting and benefiting plans for tourism, the evacuation and mitigation strategies during hazards to protect social life and environment with less infrastructure damage, marketing plans for advertising or selling of products. Despite wide spread success in predicting specific aspects of human behavior by social media information, a little attention is given to twitter and cell phone data. Accessibility to detailed human movements with fine spatial and temporal granularity is challenging due to confidentiality and safety reasons. With rapid development of web 2.0 applications people can post about events, share opinion and emotions online. Using twitter data, how short term travelers, such as tourists, can be recognized and how their travel pattern can be analyzed. Study of finding tourist dynamics such as arriving and outgoing of tourist, sum of trips, sum of days and night spent, number of unique visitors, country of residence, main destination, secondary destination, transits pass through, repeat visits are achieved using CDR (call detail records) and DDR (data detail records).
