Web 2.0 and Destination Marketing: Current Trends and Future Directions
Authors: Mariani Marcello
Published: May 2020

Over the last decade, destination marketers and Destination Marketing Organizations (DMOs) have increasingly invested in Web 2.0 technologies as a cost-effective means of promoting destinations online, in the face of drastic marketing budgets cuts. Recent scholarly and industry research has emphasized that Web 2.0 plays an increasing role in destination marketing. However, no comprehensive appraisal of this research area has been conducted so far. To address this gap, this study conducts a quantitative literature review to examine the extent to which Web 2.0 features in destination marketing research that was published until December 2019, by identifying research topics, gaps and future directions, and designing a theory-driven agenda for future research. The study’s findings indicate an increase in scholarly literature revolving around the adoption and use of Web 2.0 for destination marketing purposes. However, the emerging research field is fragmented in scope and displays several gaps. Most of the studies are descriptive in nature and a strong overarching conceptual framework that might help identify critical destination marketing problems linked to Web 2.0 technologies is missing.

Authors: Assimakopoulos Margarita-Niki , De Masi Rosa Francesca , de Rossi Filippo , Papadaki Dimitra , Ruggiero Silvia
Published: May 2020

In the 21st century, sustainable development is high on the international agenda, with the implementation of green walls contributing significantly to achieving environmental and social benefits, mainly in the frame of sustainable improvement of the building sector. The installation of a greening system can provide engineered solutions for stormwater management and climate change mitigation at both the urban and building level. This facilitates improving indoor comfort conditions and reducing energy needs. In order to improve the features of products and to facilitate the implementation of a proper technical standard, this paper proposes a critical bibliographic analysis of more recent scientific works. Moreover, by means of a numerical model of an existing single-family apartment, placed in the Mediterranean climate zone, a building envelope refurbishment with a living wall is carried out. A parametric analysis provides evidence for the application of different plants’ types and insulation materials. The results are analyzed considering the energy needs, the thermo-hygrometric comfort, and the outdoor surface temperature variation of the building envelope, emphasizing that a multi-criteria design approach is needed for green vertical systems. The paper provides data and an approach useful for designers and researchers in the evaluation and optimization of the performance of greening systems.
Using Virtual Gifts on Live Streaming Platforms as a Sustainable Strategy to Stimulate Consumers’ Green Purchase Intention
Authors: Su Qiulai , Zhou Fei , Wu Yenchun Jim
Published: May 2020

As the use of live-stream marketing by corporations to sell products is increasing, the sustainability of this marketing model has been a controversial topic in recent years. In this study, we propose that live-stream marketing can be used as a sustainable strategy to improve the relationship between customers and the companies endorsed by broadcasters. Based on signal theory and the framework of “affordance--psychological outcome--consumer behavior”, this study answers the question from the perspective of virtual gift visibility, and finds that social presence and self-esteem serve as mediators, and self-monitoring personality as a moderator, of the relationship between online visibility of virtual gifts and green purchasing. Our research model was tested using structural equation model analysis. Data were collected from 552 users of Chinese live streaming platforms in China, and it was found that online gift visibility of live-stream marketing can be used as a sustainable strategy to stimulate customers’ purchase intention. Social presence is a full mediator of the relationship between the online visibility of virtual gifts and green purchases. Furthermore, self-monitoring personality moderates the relationships among the online visibility of virtual gifts, social presence, and green purchase intention. Our research not only extends the understanding of online gifts as a link between consumers and broadcasters, but also clarifies the process of how online gifts lead to green purchase intention.

Authors: Pędzik Marta , Bednarz Joanna , Kwidziński Zdzisław , Rogoziński Tomasz , Smardzewski Jerzy
Published: May 2020

The paper concerns the importance of the trend of mass customization in building the competitive advantage of companies in the door joinery sector in Poland. Its purpose is an attempt at assessing the effects of mass customization carried out on a newly designed TechnoPORTA technological line for automated door production on the basis of an analysis of selected technical and economic indexes related to manufacturing costs. The basis for the calculation of these indexes was the value of material and labor costs and the projected production value in relation to eleven selected types of industrial doors. Based on the analysis of technical and economic indexes, it can be concluded that the introduction of the concept of mass customization will reduce gross costs of manufactured products which, with the assumed level of sales, will translate into annual profit. The results obtained allow for optimistic conclusions about the possibility of building the long-term competitive advantage of door manufacturers.
Convivial Greenstreets: A Concept for Climate-Responsive Urban Design
Authors: Tamminga Ken , Cortesão João , Bakx Michiel
Published: May 2020

This paper presents a conceptual framework for using “convivial greenstreets” (CG) as a resource for climate adaptation. When applied consistently, CG can become an emerging green practice with a positive impact on urban adaptation to climate change: CG may provide localized climate amelioration in ways that support social engagement outdoors. However, as spontaneous phenomena, CG should neither become an academic nor an aesthetic prescriptive tool. How then can CG be used as an active resource for urban adaptation to climate change while avoiding these two potential pitfalls? To explore this question, we present the concept of CG and the ways it can be situated in theoretical urbanism and analogous urban morphologies. We profile the CG inventory corpus and conceptualization that has taken place to date and expand them through a climate-responsive urban design lens. We then discuss how CG and climate-responsive urban design can be brought together while preventing the academization and aestheticizing of the former. This discussion is illustrated with a group of visualizations. We conclude by submitting that climate-responsive urban design and extensive and robust CG practices can co-operate to promote more resilient communities and urban climates. Finally, the conceptual framework herein sets an agenda for future research.

Published: May 2020

Green infrastructure (GI) contributes to improve urban drainage and also has other societal and environmental benefits that grey infrastructure usually does not have. Economic assessment for urban drainage planning and decision making often focuses on flood criteria. This study presents an economic assessment of GI based on a conventional cost-benefit analysis (CBA) that includes several benefits related to urban drainage (floods, combined sewer overflows and waste water treatment), environmental impacts (receiving water bodies) and additional societal and environmental benefits associated with GI (air quality improvements, aesthetic values, etc.). Benefits from flood damage reduction are monetized based on the widely used concept of Expected Annual Damage (EAD) that was calculated using a 1D/2D urban drainage model together with design storms and a damage model based on tailored flood depth–damage curves. Benefits from Combined Sewer Overflows (CSO) damage reduction were monetized using a 1D urban drainage model with continuous rainfall simulations and prices per cubic meter of spilled combined sewage water estimated from literature; other societal benefits were estimated using unit prices also estimated from literature. This economic assessment was applied to two different case studies: the Spanish cities of Barcelona and Badalona. The results are useful for decision making and also underline the relevancy of including not only flood damages in CBA of GI.
Compressive Sensing Based Three-Dimensional Imaging Method with Electro-Optic Modulation for Nonscanning Laser Radar
Authors: An Yulong , Zhang Yanmei , Guo Haichao , Wang Jing
Published: May 2020

Low-cost Laser Detection and Ranging (LiDAR) is crucial to three-dimensional (3D) imaging in applications such as remote sensing, target detection, and machine vision. In conventional nonscanning time-of-flight (TOF) LiDAR, the intensity map is obtained by a detector array and the depth map is measured in the time domain which requires costly sensors and short laser pulses. To overcome such limitations, this paper presents a nonscanning 3D laser imaging method that combines compressive sensing (CS) techniques and electro-optic modulation. In this novel scheme, electro-optic modulation is applied to map the range information into the intensity of echo pulses symmetrically and the measurements of pattern projection with symmetrical structure are received by the low bandwidth detector. The 3D imaging can be extracted from two gain modulated images that are recovered by solving underdetermined inverse problems. An integrated regularization model is proposed for the recovery problems and the minimization functional model is solved by a proposed algorithm applying the alternating direction method of multiplier (ADMM) technique. The simulation results on various subrates for 3D imaging indicate that our proposed method is feasible and achieves performance improvement over conventional methods in systems with hardware limitations. This novel method will be highly valuable for practical applications with advantages of low cost and flexible structure at wavelengths beyond visible spectrum.
Docking of Platinum Compounds on Cube Rhombellane Functionalized Homeomorphs
Authors: Szefler Beata , Czeleń Przemysław
Published: May 2020

Platinum compounds are anti-cancer drugs and can bind to canonical purine bases, mainly guanine, found within double helical DNA. Platinum compounds can be transferred directly to pathologically altered sites in a specific and site-oriented manner by nanocarriers as potential nanocarriers for carboplatin. Two types of nanostructures were used as potential nanocarriers for carboplatin, the first were functionalized C60 fullerene molecules and the second were rhombellanes. The analyzed nanostructures show considerable symmetry, which affects the affinity of the studied nanocarriers and ligands. Thus symmetry of nanostructures affects the distribution of binding groups on their surface. After the docking procedure, analysis of structural properties revealed many interesting features. In all described cases, binding affinities of complexes of platinum compounds with functionalized fullerene C60 are higher compared with affinities of complexes of platinum compounds with rhombellane structures. All platinum compounds easily create complexes with functionalized fullerene C60, CID_16156307, and at the same time show the highest binding affinity. The binding affinities of lobaplatin and heptaplatin are higher compared with oxaliplatin and nedaplatin. The high value of binding affinity and equilibrium constant K is correlated with creation of strong and medium hydrogen bonds or is correlated with forming a hydrogen bond network. The performed investigations enabled finding nanocarriers for lobaplatin, heptaplatin, oxaliplatin and nedaplatin molecules.

Published: May 2020

Cyber security has recently received enormous attention in today’s security concerns, due to the popularity of the Internet-of-Things (IoT), the tremendous growth of computer networks, and the huge number of relevant applications. Thus, detecting various cyber-attacks or anomalies in a network and building an effective intrusion detection system that performs an essential role in today’s security is becoming more important. Artificial intelligence, particularly machine learning techniques, can be used for building such a data-driven intelligent intrusion detection system. In order to achieve this goal, in this paper, we present an Intrusion Detection Tree (“IntruDTree”) machine-learning-based security model that first takes into account the ranking of security features according to their importance and then build a tree-based generalized intrusion detection model based on the selected important features. This model is not only effective in terms of prediction accuracy for unseen test cases but also minimizes the computational complexity of the model by reducing the feature dimensions. Finally, the effectiveness of our IntruDTree model was examined by conducting experiments on cybersecurity datasets and computing the precision, recall, fscore, accuracy, and ROC values to evaluate. We also compare the outcome results of IntruDTree model with several traditional popular machine learning methods such as the naive Bayes classifier, logistic regression, support vector machines, and k-nearest neighbor, to analyze the effectiveness of the resulting security model.
Some Generalised Fixed Point Theorems Applied to Quantum Operations
Authors: Yusuf Umar Batsari , Kumam Poom , Yoo-Kong Sikarin
Published: May 2020

In this paper, we consider an order-preserving mapping T on a complete partial b-metric space satisfying some contractive condition. We were able to show the existence and uniqueness of the fixed point of T. In the application aspect, the fidelity of quantum states was used to establish the existence of a fixed quantum state associated to an order-preserving quantum operation. The method we presented is an alternative in showing the existence of a fixed quantum state associated to quantum operations. Our method does not capitalise on the commutativity of the quantum effects with the fixed quantum state(s) (Luders’s compatibility criteria). The Luders’s compatibility criteria in higher finite dimensional spaces is rather difficult to check for any prospective fixed quantum state. Some part of our results cover the famous contractive fixed point results of Banach, Kannan and Chatterjea.
Spontaneous Chiral Symmetry Breaking and Entropy Production in a Closed System
Authors: Kondepudi Dilip , Mundy Zachary
Published: May 2020

In this short article, we present a study of theoretical model of a photochemically driven, closed chemical system in which spontaneous chiral symmetry breaking occurs. By making all the steps in the reaction elementary reaction steps, we obtained the rate of entropy production in the system and studied its behavior below and above the transition point. Our results show that the transition is similar to a second-order phase transition with rate of entropy production taking the place of entropy and the radiation intensity taking the place of the critical parameter: the steady-state entropy production, when plotted against the incident radiation intensity, has a change in its slope at the critical point. Above the critical intensity, the slope decreases, showing that asymmetric states have lower entropy than the symmetric state.
Structured Light 3D Reconstruction System Based on a Stereo Calibration Plate

Published: May 2020

Calibration is a critical step in structured light 3D imaging systems. However, in the traditional calibration process, since the calibration plate is based on a two-dimensional model, the flatness of the calibration plate and the angle of the photo will affect the subsequent stitching steps based on the feature points. The number of photos also affects the calibration results. To improve the calibration accuracy, multiple photos need to be taken. The primary objective of this study was to achieve the simple and fast calibration of system parameters, so a method obtaining a large number of calibration data by homography matrix is presented, and a corresponding stereo target is designed in symmetry. First, using the relationship between the corner coordinates of the left and right parts of the stereo calibration plate and the coordinates of the world coordinate system, the homography matrix of the left and right calibration plates from the image coordinates to the world coordinates is calculated. Second, all the pixels in the stereo calibration plate are matched to the world coordinate system by using the homography matrix. In addition, we also compared the results of this method with those of traditional calibration methods. The experimental results show that the 3D geometric surface of the reconstruction result is smooth, it avoids the missing parts and the visual effect is excellent. Furthermore, the error range of small and complex objects can be reduced to 0.03 mm~0.05 mm. This method simplifies the calibration steps, reduces the calibration costs and has practical application value.
Pathogenic Biohacking: Induction, Modulation and Subversion of Host Transcriptional Responses by Listeria monocytogenes
Authors: Eldridge Matthew J. G. , Cossart Pascale , Hamon Mélanie A.
Published: May 2020

During infection, the foodborne bacterial pathogen Listeria monocytogenes dynamically influences the gene expression profile of host cells. Infection-induced transcriptional changes are a typical feature of the host-response to bacteria and contribute to the activation of protective genes such as inflammatory cytokines. However, by using specialized virulence factors, bacterial pathogens can target signaling pathways, transcription factors, and epigenetic mechanisms to alter host gene expression, thereby reprogramming the response to infection. Therefore, the transcriptional profile that is established in the host is delicately balanced between antibacterial responses and pathogenesis, where any change in host gene expression might significantly influence the outcome of infection. In this review, we discuss the known transcriptional and epigenetic processes that are engaged during Listeria monocytogenes infection, the virulence factors that can remodel them, and the impact these processes have on the outcome of infection.

Published: May 2020

Lake Steinsfjorden, an important Norwegian location for noble crayfish (Astacus astacus), is often affected by cyanobacterial blooms caused by microcystin (MC)-producing Planktothrix spp. The impact of MCs on noble crayfish as a food source and crayfish health is largely unknown. We investigated the quantities and correlations of MCs in noble crayfish and lake water during and after a cyanobacterial bloom peaking in June–July 2015. Noble crayfish and water samples were collected monthly from June to October 2015 and in October 2016. The content of MCs was analysed by ELISA from tail muscle, intestine, stomach and hepatopancreas. PCR analysis for Planktothrix gene markers was performed on crayfish stomach content. Water samples were analysed for phytoplankton composition, biomass and MCs. PCR-positive stomach contents indicated Planktothrix to be part of the noble crayfish diet. Concentrations of MCs were highest in the hepatopancreas, stomach and intestine, peaking in August–September. Tail muscle contained low concentrations of MCs. Similar levels of MCs were found in crayfish from 2016. Except in September 2015, a normal portion of boiled noble crayfish tails was below the tolerable daily intake (TDI) for MCs for humans. Removing the intestine more than halved the content of MCs and seems a reasonable precautionary measure for noble crayfish consumers.

Published: May 2020

Aflatoxin B1 (AFB1), which has potent toxicity and carcinogenicity, is a common contaminant of important agricultural commodities. This study aimed to investigate the frequency of corn flour intake and assess the exposure to AFB1 via direct detection of AFB1 in the diet and serum AFB1 exposure biomarker, so as to evaluate their associations with the risk of esophageal precancerous lesions (EPL). A case-control study based on three-day duplicate diet samples was performed in Huai’an District. One hundred EPL cases and 100 healthy controls were enrolled and required to be age- (±2 years) and gender-matched. The concentration of AFB1 in food samples and the level of serum AFB1-albumin (AFB1-Alb) adduct were quantitatively analyzed. Results showed that corn flour intake was positively associated with serum AFB1-Alb adduct level (p for trend = 0.003), dietary AFB1 exposure (p for trend < 0.001), and the risk of EPL (p for trend = 0.017). Increased serum AFB1-Alb adduct level was associated with an increased risk of EPL as well (p for trend < 0.001). In conclusion, corn flour may be an essential source of AFB1 in Huai’an District, whereas high exposure to AFB1 is likely to be an important risk factor contributing to the progression of EPL.

Chikungunya virus (CHIKV), Ross River virus (RRV), o’nyong nyong virus (ONNV), Mayaro virus (MAYV) and Getah virus (GETV) represent arthritogenic alphaviruses belonging to the Semliki Forest virus antigenic complex. Antibodies raised against one of these viruses can cross-react with other serogroup members, suggesting that, for instance, a CHIKV vaccine (deemed commercially viable) might provide cross-protection against antigenically related alphaviruses. Herein we use human alphavirus isolates (including a new human RRV isolate) and wild-type mice to explore whether infection with one virus leads to cross-protection against viremia after challenge with other members of the antigenic complex. Persistently infected Rag1-/- mice were also used to assess the cross-protective capacity of convalescent CHIKV serum. We also assessed the ability of a recombinant poxvirus-based CHIKV vaccine and a commercially available formalin-fixed, whole-virus GETV vaccine to induce cross-protective responses. Although cross-protection and/or cross-reactivity were clearly evident, they were not universal and were often suboptimal. Even for the more closely related viruses (e.g., CHIKV and ONNV, or RRV and GETV), vaccine-mediated neutralization and/or protection against the intended homologous target was significantly more effective than cross-neutralization and/or cross-protection against the heterologous virus. Effective vaccine-mediated cross-protection would thus likely require a higher dose and/or more vaccinations, which is likely to be unattractive to regulators and vaccine manufacturers.
Comprehensive Analysis of Coordination Relationship between Water Resources Environment and High-Quality Economic Development in Urban Agglomeration in the Middle Reaches of Yangtze River
Authors: Zhu Hua , Zhu Jinsheng , Zou Qiang
Published: May 2020

Water resources environment and high-quality economic development both have crucial significance to sustainable development. To explore the nexus between them, an integrated evaluation system was firstly established in this study on the basis of their complicated synergy mechanism. Secondly, the index weights of urban agglomeration in the middle reaches of the Yangtze River from 2008 to 2017 were calculated by project pursuit-entropy weight method (PP-EWM) combined with an immune grey wolf optimizer algorithm (IGWO). Finally, the static and dynamic coordination degrees of 31 cities in the urban agglomeration were measured by membership function coordination model (MFCM), and the temporal and spatial characteristics of the coordination degrees were analyzed. The results showed that: (1) most cities in the urban agglomeration still had some room for improvement in terms of the water resources environment and high-quality economic development; (2) according to the changing characteristics of static coordination degrees, 31 cities were divided into five types, namely constantly rising type, constantly declining type, rising-declining type, declining-rising type and fluctuation type; (3) the dynamic coordination degrees demonstrated that the number of well coordinated cities decreased in recent years, and Xinyu and three provincial cities (i.e., Wuhan, Changsha and Nanchang) had poor performances. Overall, this study contributed to decision-making on synergic improvement between the water resources environment and high-quality economic development.
Accounting for Dissolved Organic Nutrients in an SPBEM-2 Model: Validation and Verification
Authors: Isaev Alexey , Vladimirova Oksana , Eremina Tatjana , Ryabchenko Vladimir , Savchuk Oleg
Published: May 2020

Modern models of the Baltic Sea eutrophication describe only a bioavailable fraction of the nutrient input from land, thus introducing uncertainty into forcing. In order to alleviate this uncertainty, the coupled 3D hydrodynamical-biogeochemical St. Petersburg Eutrophication Model (SPBEM) has been expanded with variables representing dissolved organic nutrients. The model modification involves an explicit description of the labile and refractory fractions of dissolved organic nitrogen and phosphorus, in addition to their particulate forms, represented by the detritus variables. The modified SPBEM-2 allows for a full account of the total amounts of nutrients reported in field measurements and presented in environmental documents. Particularly, a model description of detritus, as the only bulk organic matter variable, has been replaced by more realistic parameterizations with adequate rates of settling and mineralization. The extensive validation and verification of the model performance in the Gulf of Finland from 2009 to 2014, based on over 4000 oceanographic stations, shows that SPBEM-2 plausibly reproduces all the major large-scale features and phenomena of the ecosystem dynamics in the Gulf of Finland, especially in its surface productive layer. These demonstrated capabilities of SPBEM-2 make the model a useful tool, both in studies of biogeochemical interactions and in historical and scenario simulations.
Assessing Impact of Climate Change on Hydrology of Melka Kuntrie Subbasin, Ethiopia with Ar4 and Ar5 Projections
Authors: Getahun Yitea Seneshaw , Li Ming-Hsu , Chen Pei-Yuan
Published: May 2020

Assessing future challenges in water resources management is crucial to the Melka Kuntrie (MK) subbasin suffering water shortage. Impact assessments are evaluated by the HBV hydrological model with six scenarios, including two GCMs of AR4-A2 and two GCMs of AR5-RCP4.5 and RCP8.5, for the time periods 2021–2050 and 2071–2100. Evapotranspiration is expected to increase under all scenarios—due to rising temperature—and induce more water stress on rainfed agriculture of the area. However, the increase in the monthly minimum temperature is beneficial to crops against chilling damages. Five out of six projections show significant increases of rainfall and streamflow in both annual and major rainy seasons, except ECHAM-A2. Annual rainfall (streamflow) is expected to increase by 38% (23%) and 57% (49%) during 2021–2050 and 2071–2100, respectively, under RCP8.5 scenarios. Greater flashflood risk is a concern because of the projected increase in streamflow. The projection of decreased streamflow with ECHAM-A2 will exacerbate the existing water shortage, especially in the minor rainy season. Water harvesting during the major rainy season would be vital to enhance water management capacities and reduce flashflood risks. Lacking sufficient hydraulic and irrigation infrastructures, the MK subbasin will be more vulnerable to the impacts of climate change.
Tap Water, Bottled Water or In-Home Water Treatment Systems: Insights on Household Perceptions and Choices
Authors: March Hug , Garcia Xavier , Domene Elena , Sauri David
Published: May 2020

This article addresses household strategies for coping with perceived tap water quality issues. By using a household survey (n = 581) in Catalonia (Spain) and three models, this article analyses the drivers and motivations behind the installation of in-home water treatment systems, and the use of bottled water for drinking and cooking. The main explanatory factors of the higher consumption of bottled water were the perception of poor tap water quality, the lack of in-home treatment systems, and the presence of children at home. Income did not appear as a significant variable explaining the use of bottled water, unlike in other studies. The presence of in-home treatment systems is related to factors, such as perceived bad water quality, larger households, and single-family housing. Income and housing tenure appeared as explanatory variables only when considering systems requiring some kind of installation: lower incomes or renting a multi-family house reduce the probability of having an in-home water treatment that required installation because of important investments and operating costs, and the space needed in the housing units. In-house water treatment systems may become a solid alternative to bottled water when tap water raises problematic perceptions related to bad taste, odor, or lime presence.
Understanding the Ecological Response of Planktic and Benthic Epipelic Algae to Environmental Factors in an Urban Rivers System
Authors: Xia Liling , Zhu Yuelong , Zhao Zhenhua
Published: May 2020

Many studies have been concentrated on the distribution of algae in lakes, rivers, and seas, however, few studies have been concerned about their distribution and relation with polluted urban rivers. In this study, the spatio-temporal variation characteristics of water quality and algae community in Nanjing city were investigated with microscopic examination for one year. Results showed that the water pollution in this area was mainly related to high concentration of nitrogen (NH3-N and TN (Total nitrogen). There was a total of 77 species of algae in the studied rivers from June 2016 to May 2017, among which 73 species of planktic algae and 34 species of epipelic algae, in which the abundance and biomass of the latter were 1925 and 904 times that of the former, respectively. The two kinds of algae had different change tendencies which were related to seasons. For planktic algae, the abundance and biomass decreased in this season sequence: summer, spring, autumn, and winter. For epipelic algae, the abundance and biomass were relatively higher in winter. The dominant community of planktic algae was Chlorophyta-Bacillariophyceae-Cyanobacteria type, while that of epipelic algae was Bacillariophyceae—Cyanobacteria type. Most of the present algae were bi-trophic species, and were tightly related to the pollution characteristics of the rivers. The key environmental factors for planktic algae are T, TN, and TP, and those for Epipelic algae are N:P and TN. The relation between the community composition of planktic and epipelic algae and environmental parameters are highly complex, and it is worth carrying out further study to clarify their interaction mechanism.
Enhancing Water Infiltration through Heavy Soils with Sand-Ditch Technique
Authors: Abu-Zreig Majed , Fujimaki Haruyuki , Abd Elbasit Mohamed Ahmed
Published: May 2020

Enhancing rainwater infiltration into heavy soils is an important strategy in arid regions to increase soil water storage and meet crop water demand. In such soils, water infiltration and deep percolation can be enhanced by constructing deep ditches filled with permeable materials, such as sand. Laboratory experiments were conducted to examine the effect of sand ditch installed across the slope of a soil box, 50 × 20 × 20 cm3, on runoff interception and water infiltration of clay soil packed at two bulk densities, 1240 and 1510 kg/m3. The experiments were carried out under laboratory conditions using simulated steady flow of about 20 cm/h for a duration of 60 min. Results showed that sand ditches highly reduced runoff and largely enhanced water infiltration into soils. In low-density soil, the average runoff was 15% of inflow volume but reduced to zero in the presence of sand ditches thus increasing soil water storage by 15%. In high-density soil, the presence of sand ditches was more effective; infiltration volume increased by 156% compared to control. The WASH_2D model was used to simulate water flow in the presence of sand ditches; it showed to increase water infiltration and soil-moisture storage thus improving crop production in drylands.

O Estado Novo português e os estudos sobre a Reforma Administrativa (1965-1969)
Authors: Ana Carina Azevedo
Published: May 2020

Em meados da década de 1960, tem lugar em Portugal uma aposta nos estudos sobre a Administração Pública nacional e a sua relação com o desenvolvimento económico. Em 1965 é criado o Grupo de Trabalho n.º 14, no seio da Comissão Interministerial de Planeamento e Integração Económica, que permaneceria em funções até 1969. Subdividido em cinco subgrupos, este organismo foi responsável pelos mais aturados estudos sobre a Administração Pública Portuguesa realizados durante o Estado Novo. Dos seus trabalhos nasceria, em 1967, o Secretariado da Reforma Administrativa.A análise dos relatórios produzidos, em grande medida inéditos, permite entender que as conclusões do Grupo de Trabalho n.º 14 foram, simultaneamente, devedoras do caminho trilhado desde 1950 e responsáveis pelas decisões apresentadas no programa de reforma de 1968. De facto, a ordem de trabalhos de cada subgrupo reflete as prioridades atribuídas, desde a década anterior, à reforma da Administração Central: a situação dos funcionários públicos, a problemática da organização e métodos, a reforma administrativa e as suas relações com o processo de desenvolvimento económico e social.Utilizando documentação produzida pelos cinco subgrupos, este artigo pretende incidir sobre os estudos desenvolvidos pelo Grupo de Trabalho n.º 14, de modo a desvendar as suas principais conclusões e o seu impacto no processo que viria a dar origem às bases do programa de reforma administrativa apresentado pelo Estado Novo em 1968.
Revisitando o nascimento da teoria feminista no Brasil a partir de A mulher é uma degenerada, de Maria Lacerda de Moura
Authors: De Figueiredo Fiuza Adriana Aparecida , Pinheiro Achre Simone
Published: May 2020

Uma das grandes expoentes das teorias do feminismo é Maria Lacerda de Moura. Por meio de seus textos é possível entender a condição das mulheres no Brasil no século XX e quais são as ações necessárias para a libertação das amarras do patriarcado. Esses aspectos podem ser lidos em A Mulher é uma degenerada (1924). O objetivo do artigo é analisar a obra, percebendo a visão da autora quanto ao papel da mulher e de como o resgate de sua obra contribui para a discussão acerca do nascimento e da memória do movimento feminista no país. O suporte teórico está centrado em estudos de Walter Benjamin e Michel Foucault, entre outros. Esse trabalho se justifica dada a necessidade de rever a história e demonstrar os silenciamentos no discurso oficial, pois se percebe que a luta pela emancipação da mulher tem o seu surgimento muito antes da década de 1970, uma vez que nos anos 20 do século passado Maria Lacerda de Moura, desde uma perspectiva anarquista, já levantava a bandeira da emancipação feminina e da luta por direitos igualitários entre homens e mulheres. Acredita-se que ao se revisitar a teoria feminista contribui-se para a formação de uma memória nacional sobre a luta por direitos das mulheres.

DLRCNeg: Deep Learning based Reading Comprehension by handling Negation

Question Answer (QA) System for Reading Comprehension (RC) is a computerized approach to retrieve relevant response to the query posted by the users. The underlined concept in developing such a system is to build a human computer interaction. The interactions will be in natural language and we tend to use negation words as a part of our expressions. During the pre-processing stage in Natural Language Processing (NLP) task these negation words gets removed and hence the semantics gets changed. This remains to be an unsolved problem in QA system. In order to maintain the semantics we have proposed a novel approach Hybrid NLP based Bi-directional Long Short Term Memory (Bi-LSTM) with attention mechanism. It deals with the negation words and maintains the semantics of the sentence. We also focus on answering any factoid query (i.e. ’what’, ’when’, ’where’, ’who’) that is raised by the user. For this purpose, the use of attention mechanism with softmax activation function has obtained superior results that matches the question type and process the context information effectively. The experimental results are performed over the SQuAD dataset for reading comprehension and the Stanford Negation dataset is used to perform the negation in the RC sentence. The accuracy of the system over negation is obtained as 93.9% and over the QA system is 87%.
Kidney Transplantation in Patients with HIV
Authors: Sawinski Deirdre
Published: May 2020

Individuals with HIV are at increased risk for ESKD. Kidney transplantation is the best treatment for ESKD in the HIV+ population. Despite reduced access to transplantation, patients who are HIV+ have excellent outcomes and clearly benefit from receiving one. Common post-transplant complications and management concerns, including the optimal antiretroviral regimen, immunosuppression protocols, infectious prophylaxis, hepatitis C coinfection, metabolic complications, and malignancy are all discussed.
A review on promising strategy to decrease sludge production: Oxic-settling-anoxic/anaerobic process
Authors: Karlikanovaite-balıkçı Agne , Yağcı Nevin
Published: May 2020

Recently, as environmental regulation for the removal of nutrients and excess sludge produced through wastewater treatment has become more restricted, many wastewater treatment plants face serious challenges in terms of waste production. Nowadays, the issue of excess sludge production has received considerable critical attention. Recent developments in sludge treatment technologies have heightened the need for more promising strategies to reduce sludge levels in a cost-effective and environmentally friendly manner. The purpose of this paper is to review recent research into the oxic-settling-anaerobic/anoxic (OSA) technology for sludge minimization. The OSA process is a modification of a conventional activated sludge system with the addition of interchange bioreactor parallel to recycled activated sludge line. The OSA process seems to be a revolutionary and cost-effective alternative for sludge reduction approach in the future. It is hoped that this research will contribute to a deeper understanding of the OSA process in terms of sludge reduction efficiency, carbon and nutrient removal, operational parameters, possible reduction mechanisms and microbial community changes after the implementation of the OSA system and applied in the treatment of real wastewater at full-scale.
Fajeros pamploneses: de oficio humilde a solemne cometido
Authors: Gurbindo Gil Ricardo

RESUMEN
En tiempos pasados, el recurso a la fortaleza física resultaba indispensable para el desarrollo de la mayor parte de las actividades laborales. Este era el caso de los cargadores o mozos de carga, los cuales en nuestro entorno eran conocidos con la denominación de fajeros. De igual manera que sucede con otros oficios de condición modesta, y por más que en la actualidad el término siga vigente en determinadas tradiciones religiosas señaladas de Pamplona, nuestros conocimientos acerca de estos trabajadores son muy limitados. Este es precisamente el propósito del presente trabajo: acercarnos a los orígenes y particularidades de esta antigua ocupación que se ha mantenido en vigor hasta hace escasas décadas.

LABURPENA
Iraganeko garaietan, lan-jarduera gehienak garatu ahal izateko giza sendotasuna
ezinbestekoa suertatzen zen. Halaxe zen zamaketari edo soinkarien kasuan, zeinak
gure inguruan «fajero» izenarekin ezagutzen baitziren. Izaera apaleko beste ofizioetan
gertatzen den bezala, eta gaur egun hitza Iruñeko tradizio erlijioso zehatz batzuetan
oraindik erabiltzen den arren, langile hauei buruzko gure ezagutzak oso murritzak
dira. Hori da hain zuzen ere lan honen helburua: duela hamarkada gutxi batzuk arte
indarrean egon den antzinako lanbide honen jatorria eta bere berezitasunak hurbiletik
ezagutzea.

ABSTRACT
In the past, the use of physical strength was essential for the development of most of
the work activities. This was the case of the cargo porters or porters, who in our environment were known as «fajeros». In the same way that happens with other trades of modest condition, and even though the term is still valid in certain designated religious traditions of Pamplona, our knowledge about these workers is very limited. This is precisely the purpose of this article: to approach the origins and particularities of this old occupation that has remained in force until a few decades ago.
Altxunbidëa. Estudio etnofotográfico del ciclo anual trashumante roncalés
Authors: Orduna Portús Carlos
Published: May 2020

RESUMEN Este estudio contribuye al análisis de un ciclo anual de ganadería extensiva desde una perspectiva transversal. En el trabajo se estudian los estadíos del pastoreo invernal en el semidesierto de las Bardenas, los usos y disfrutes de los puertos de la montaña y ambas cabañeras de desplazamiento entre las dos regiones geográficas y climáticas. En los resultados gráficos del análisis se observa no solo su componente de permanencia en las costumbres locales sino también las rápidas trasformaciones actuales palpables en su significación dentro del paisaje cultural de esta sociedad pirenaica. Se logra contextualizar un sistema pastoril que imperó hasta hace no mucho, no solo en Navarra sino en toda la señalada cordillera montañosa y en la depresión del Ebro. LABURPENA Azterlan honek abeltzaintza zabala urteko zikloa zeharkako ikuspegitik ikertzen laguntzen du. Lanean neguko artzaintzaren egonaldiak aztertzen ditugu Bardeako basamortuan edo mendiko larretan erabilerak eta gozamenak eta bi eskualde geografiko eta klimatikoen arteko abelbideak. Ikerlanaren emaitza grafikoetan, tokiko ohituretan iraunkortasunaren egiturak eta egungo eraldaketa azkarrak ere ikusten dira. Pirinioetako gizarte honetako kultura paisaian, aldaketa hauek haien garrantzia ikusgai daude. Ikuspuntu integraletik, artzain-errealitatearen bilakaera maila grafikoan eta antropologikoki testuinguruan ahala da. Horrela, Nafarroan eta beste toki batzuetan, gaur egungo abeltzaintza ereduaren bilakaeraren ebaluazioarekin amaitu da. ABSTRACT The work analyzes the annual cycle of extensive livestock farming from a transversal perspective. This paper concerns the studies of the stages of winter grazing in the semi-desert of the Bardenas, the uses and enjoyments of the mountain pastures and the cattle routes between the two geographical and climatic regions. Paper aims to contextualize by graphs the analysis of the customs and anthropological level the evolution of this pastoralist reality from an integral perspective and clear expository discourse. Thus, the study concludes with an assessment of the evolution, loss or conservation of character traits of this stock model in the mountain range and the Ebro Lowland.
