Published: April 2016

ENTICE is an H2020 European project aiming to research and create a novel Virtual Machine (VM) repository and operational environment for federated Cloud infrastructures to: (i) simplify the creation of lightweight and highly optimised VM images tuned for functional descriptions of applications; (ii) automatically decompose and distribute VM images based on multi-objective optimisation (performance, economic costs, storage size, and QoS needs) and a knowledge base and reasoning infrastructure to meet application runtime requirements; and (iii) elastically auto-scale applications on Cloud resources based on their fluctuating load with optimised VM interoperability across Cloud infrastructures and without provider lock-in, in order to finally fulfil the promises that virtualization technology has failed to deliver so far. In this chapter, we give an inside view into the ENTICE project architecture. Based on stakeholders that interact with ENTICE, we describe the different functionalities of the different components and services and how they interact with each other.

Many e-science initiatives are currently investigating the use of cloud computing to support all kinds of scientific activities. The objective of this chapter is to describe the architecture and the deployment of the EUBrazilCC federated e-infrastructure, a Research & Development project that aims at providing a user-centric test bench enabling European and Brazilian research communities to test the deployment and execution of scientific applications on a federated intercontinental e-infrastructure. This e-infrastructure exploits existing resources that consist of virtualized data centers, supercomputers, and even opportunistically exploited desktops spread over a transatlantic geographic area. These heterogeneous resources are federated with the aid of appropriate middleware that provide the necessary features to achieve the established challenging goals. In order to elicit the requirements and validate the resulting infrastructure, three complex scientific applications have been implemented, which are also presented here.
Volunteer Clouds
Authors: Marosi Attila Csaba , Kacsuk Péter
Published: April 2016

Cloud Computing (CC) offers simple and cost effective outsourcing in dynamic service environments and allows the construction of service-based applications extensible with the latest achievements of diverse research areas. CC is built using dedicated and reliable resources and provides uniform seemingly unlimited capacities. Volunteer Computing (VC) on the other hand uses volatile, heterogeneous and unreliable resources. This chapter per the authors makes an attempt starting from a definition for Cloud Computing to identify the required steps and formulate a definition for what can be considered as the next evolutionary stage for Volunteer Computing: Volunteer Clouds (VCl). There are many idiosyncrasies of VC to overcome (e.g., volatility, heterogeneity, reliability, responsiveness, scalability, etc.). Heterogeneity exists in VC at different levels. The vision of CC promises to provide a homogeneous environment. The goal of this chapter per the authors is to identify methods and propose solutions that tackle the heterogeneities and thus, make a step towards Volunteer Clouds.
Geocoding of Spatial Relationships Contained in Tweets
Authors: Escamilla Imelda , Davis Jr. Clodoveu A. , Moreno-Ibarra Marco , Luna Vladimir
Published: April 2016

Human ability to understand approximate references to locations, disambiguated by means of context and reasoning about spatial relationships, is the key to describe spatial environments and to share information about them. In this paper, the authors propose an approach for geocoding that takes advantage of the spatial relationships contained in the text of tweets, using semantic and spatial analyses. Microblog text has special characteristics (e.g. slang, abbreviations, acronyms, etc.) and thus represents a special variation of natural language. The main objective of this work is to associate spatial relationships found in text with a spatial footprint, to determine the location of the event described in the tweet. The feasibility of the proposal is demostrated using a corpus of 200,000 tweets posted in Spanish related with traffic events in Mexico City.
Navigating News Programs in Large TV-Streams
Authors: Mahdi Walid , Zlitni Tarek
Published: April 2016

The different uses of large TV streams have continued to diversify since the appearance of digital TV. For conveniently retrieving and navigating in TV streams, users are often interested in new content-based multimedia applications of high added value such as Interactive TV, Video on Demand (VoD), YouTube or Dailymotion. These applications offer fast and easy access to best explore a particular TV program. So, the automatic process of TV program identification and their internal segmentation facilitate the availability of these programs. Therefore, it is necessary at first, to be able to retrieve a particular program within a large TV stream and secondly segment this program into semantic units related to appropriate retrieval entities. In this paper, the major originality of the authors' approach is the use of contextual and operational characteristics of TV production/post-production rules as prior knowledge that captures the structure for recurrent TV news program content. The authors validate their approach by experiments conducted using the TRECVID dataset that demonstrate its robustness.

Published: April 2016

Service quality is one of the key factors in determining the success or failure of e-banking. To gain and sustain competitive advantages in the rival-driven e-banking market, it is thus crucial for e-banks to understand in-depth what customers perceive to be the key dimensions of service quality and what impacts the identified dimensions have on the customers' perceived overall service quality, satisfaction, and loyalty. This paper attempts, based on an extensive review of relevant literature, to provide a model integrating internet banking service quality dimensions, overall internet banking service quality, customer satisfaction and customer loyalty in the context of Vietnam - emerging as a new potential market. The findings of this study indicate that three dimensions of internet banking service quality namely online customer service quality, online information system quality and banking service product quality are found to be statistically significant in determining overall internet banking service quality. In addition, overall internet banking service quality has significant impact on customer satisfaction and in turn customer satisfaction has significant impact on customer loyalty. Implications and recommendations are discussed with the aim of improving internet banking services, customer satisfaction and customer loyalty.

Published: April 2016

Development of supplier base is becoming mandatory for buyers, as it is not possible to manufacture all components in house, or to search new supplier every time. It is recommended that supplier base of buyer should be self-efficient and developed one to achieve competitive advantages. This development of supplier can be achieved by applying different supplier development practices and buyer supplier relationship practices as per the requirement. In this article, Exploratory Factor analysis (EFA) is applied for grouping the critical success factors with their items by using SPSS software. 6 factors viz., Drivers for Supplier Development Practices, Supplier Development Practices, Buyer supplier Relationship Practices, Buyer supplier Relationship Improvement, Competitive Advantages and Profitability were formed with their respective items. The multi-item scale shows strong evidence of reliability as well as convergent, discriminant validity in a sample. EFA and Reliability Analysis were applied on data for validation of instrument. Data from 87 respondents working in manufacturing sector were used for analysis.

Authors: Rodríguez-de-Dios Isabel , Igartua Juan-José
Published: April 2016

New technologies are fully integrated into the lives of children, so every day they spend more and more time using them. It is noteworthy that technologies offer many opportunities and benefits for children, but they are also associated with disadvantages and dangers. For this reason, parents and educators fear that children could suffer any of the network risks: exposure to pornography, cyberbullying, sexual harassment or grooming, sexting, contact with strangers, and impersonation. In this situation, the authors should not deprive minors of the use of digital technologies. Nevertheless, the solution is to provide them with digital skills so they become digital literate and can use these tools safely. Therefore, through this study they sought to identify the skills that compound digital literacy: technological or instrumental, communication, information, critical, and security. Finally, the authors propose the implementation of a literacy intervention with the aim of providing the children with these skills.
Decline of Real Power Loss by the Combination of Ant Colony Optimization and Simulated Annealing Algorithm
Authors: Lenin K. , Ravindhranath Reddy B. , Suryakalavathi M.
Published: April 2016

Combination of ant colony optimization (ACO) algorithm and simulated annealing (SA) algorithm has been done to solve the reactive power problem.In this proposed combined algorithm (CA), the leads of parallel, collaborative and positive feedback of the ACO algorithm has been used to apply the global exploration in the current temperature. An adaptive modification threshold approach is used to progress the space exploration and balance the local exploitation. When the calculation process of the ACO algorithm falls into the inactivity, immediately SA algorithm is used to get a local optimal solution. Obtained finest solution of the ACO algorithm is considered as primary solution for SA algorithm, and then a fine exploration is executed in the neighborhood. Very importantly the probabilistic jumping property of the SA algorithm is used effectively to avoid solution falling into local optimum. The proposed combined algorithm (CA) approach has been tested in standard IEEE 30 bus test system and simulation results show obviously about the better performance of the proposed algorithm in reducing the real power loss with control variables within the limits.

Authors: Tola Omokhafe James , Zungeru Adamu Murtala , Usifo F.O. , Garba Ambafi James
Published: April 2016

The world’s energy requirement has been dominated by petroleum oil resources for years in many applications, especially in the area of electricity generation and utilization. Mineral oil application in power system equipment can be potentially hazardous to the environment, especially when there are incidents of transformer explosion, which caused spillages of oil to the soils or water streams and thereby pollute the surrounding environments. This paper is aimed at finding a substitute for the use of mineral oil as transformer oil. Experiments on breakdown voltages, flash points, pour points, viscosities, densities and insulation resistances on conventional mineral oil and some selected vegetable oils were conducted, analyzed and compared to the internationally accepted standards, ASTM (America Standard Test of Material). Rubber seed oil, Palm oil, Mellon oil, Ground oil and Palm kernel oil were found to have good electrical, chemical and thermal properties which the transformer oil has.

Authors: Saha Abhijit , Majumder Himadri
Published: April 2016

Turning is one amongst the most adequate and cost-effective method in manufacturing environment. To meet the difficulties of extensive competitiveness in manufacturing industry the issues of selecting best preferable methodologies, design of process, machine and equipment becomes more mind boggling as there are lots of options in view of conflicting criteria. To help these selection processes, different Multi Criterion Decision-Making (MCDM) techniques are currently accessible. In this paper, MCDM technique was performed considering hybrid approach comprehensive grey complex proportional assessment (COPRAS-G) to identify optimal parameters for important multi-performance criteria like Surface roughness, power consumption and frequency of tool vibration. The important process parameters used during turning of ASTM A36 mild steel were depth of cut, spindle speed and feed using full factorial Taguchi’s design of experiment. Finally, optimal settings of input process parameters were found as speed: 160 r.p.m., depth of cut: 0.1 mm. and feed rate: 0.08 mm/rev. This study aimed to focus the applicability of COPRAS-G as a strategic decision making tool to handle multi objective optimization problem for tuning operation.

Authors: Khan Akhtar , Maity Kali Pada
Published: April 2016

Optimization of non-conventional machining (NCM) processes viz. AJM, AWJM, EDM, WEDM, ECM, ECMM, LBM, PAC, etc. has always been an open research area for researchers. In recent manufacturing environment, almost all the NCM processes consist of a number of input and output to be considered together. The purpose of the present article is to highlight the application of a multi-criteria decision making (MCDM) based method called Technique of Order Preference by Similarity of Ideal Solution (TOPSIS) in optimization of some modern manufacturing processes (MMPs). In the present paper, seven different MMPs namely Electro Chemical Honing (ECH), Abrasive Water Jet Machining (AWJM), Abrasive Jet Machining (AJM), Laser Beam Machining (LBM), Plasma Arc Cutting (PAC), Laser Cutting (LC) and Electric Discharge Machining (EDM) were exemplified. The multiple outcomes of all the illustrated MMPs have been optimized simultaneously by using TOPSIS method. It is a simple, systematic, and logical technique which can be employed to obtain the best parametric combination of cutting parameters. It was observed that the results attained by using TOPSIS method were almost tie with those derived by past researchers. This proves the applicability and adaptability of the TOPSIS method while solving different MCDM-based problems in a real manufacturing system.

Published: April 2016

Using from Stone factory waste was obtained a high-quality artificial stone. The basis of these stones is factory waste; i. Sludge stone cutting factory (SSCF) and ii. The pure waste of travertine stone (WTS).Basic formulation of artificial stone is SSCF or WTS, 50 wt.% of sludge stone is cement, 12 wt.% of cement is unsaturated polyester resin (UPR), 25 wt.% is water, 7 wt.% is the filler consists of micro-silica and different amounts of TiO2-NP. Artificial stones production with this method than to natural stone are pressure-resistant, highly flexible, resistant to freezing and scrapes, lightweight, ability to cut and form the low thickness and is self-cleaning.Artificial stones made of SSCF in all mechanical properties are better than WTS, because the density of the SSCF is much greater than the powder prepared from WST and SSCF is all wastewater leaving the factory after cutting various types of decorative stones. As well as for preparation of artificial stone from WTS should be done once milled and powdered waste, this step increases the cost of them.Keywords: Artificial stone; Sludge stone cutting factory (SSCF); Waste of travertine stone (WTS); Nanoparticles of TiO2; Cement.

Published: April 2016

A hot filament thermal chemical vapor deposition (CVD) reactor was used to deposit solid thin films on stainless steel 316 (SS 316) and stainless steel 201 (SS 201) substrates at different flow rates of acetylene (C2H2) gas. The variation of thin film deposition rate with the variation of gas flow rate has been investigated experimentally. During experiments are conducted under gas flow rate (1-5) lit/min gas flow rate, duration of deposition (10-60 min), pressure (0.2-1 bar), average surface roughness (0.3-1.05) µm and temperature 800 °C considered. Experimental results show that deposition rate on SS 316 and SS 201 increases with the increase in gas flow rate. The deposition rate also shows increasing trend with pressure and duration of deposition. Under the above mentioned experimental conditions deposition is found to be maximum of SS-316 compared to SS-201. In relation to roughness the maximum deposition is found at 0.5 microns but comparing the both materials -316 and-201 highest of deposition rate is obtained from SS-316.

Importance of an Early Diagnosis in Primary Adenocarcinoma of the Seminal Vesicle
Authors: Dell'Atti Lucio
Published: April 2016

The prognosis of seminal vesicle (SV) adenocarcinoma is often poor due to delayed diagnosis. About 95% of the patients die in less than 3 years. Diagnosis is difficult due to the absence of early clinical signs as hematuria, hematospermia and/or dysuria. We present the case of a 61-year-old Caucasian man with a left SV mass detected by transrectal ultrasound. SV ultrasound-guided biopsy showed an adenocarcinoma. The tumor was uniformly strongly immunoreactive for cytokeratin-7 and carcinoembryonic antigen. There was no immunoreactivity for prostate-specific acid phosphatase (PSAP) and CK-20. These tumors have been reported to be also positive for CA-125. Therefore a combination of positive staining for CK-7, CEA and CA-125; with negative staining for CK-20, PSA and PSAP is the pattern of immunohistochemical findings noted for this rare tumor. The computed tomography of the abdomen-pelvis and chest X-ray was negative for metastases. The patient underwent a radical prostatectomy and lymphadenectomy. The prostate, rectum, bladder and lymph nodes were free from tumor involvement. The patient did not receive any adjuvant chemotherapy or radiation; and remains free of disease 3 years post-surgery.
An insight into pre-Columbian raised fields: The case of San Borja, Bolivian lowlands
Authors: Rodrigues Leonor , Lombardo Umberto , Trauerstein Mareike , Huber Perrine , Mohr Sandra , Veit Heinz
Published: April 2016

Abstract. Pre-Columbian raised field agriculture in the tropical lowlands of South America has received increasing attention and been the focus of heated debates regarding its function, productivity, and role in the development of pre-Columbian societies. Even though raised fields are all associated to permanent or semi-permanent high water levels, they occur in different environmental contexts. Very few field-based studies on raised fields have been carried out in the tropical lowlands and little is known about their use and past management. Based on topographic surveying and mapping, soil physical/chemical analysis and OSL and radiocarbon dating, this paper provides insight into the morphology, functioning and time frame of the use of raised fields in the south-western Llanos de Moxos, Bolivian Amazon. We have studied raised fields of different sizes that were built in an area, near the town of San Borja, with a complex fluvial history. The results show that differences in field size and height are the result of an adaptation to a site where soil properties vary significantly on a scale of tens to hundreds of meters. The analysis and dating of the raised fields sediments point towards an extensive and rather brief use of the raised fields, for about 100–200 years at the beginning of the 2nd millennium.
Retrospective Data about the Catheter-related Complications and Management in Massive Bus Burn Casualties
Authors: Jiang Hongfei , Hu Hang , Ren Haitao , Han Chunmao , Wang Xingang , You Chuangang , Zhao Ruiyi
Published: April 2016

Purpose

This is a single-center, descriptive report of the management and complications of venous catheter use in 19 severely burned passengers from a bus fire that occurred on July 5, 2014, in Hangzhou.

Methods

We recorded the parameters of the catheters insertion and indwelling. Sampling of each removed catheter was conducted to monitor for catheter-related infections. Bedside ultrasound screening was performed for recording central venous catheter (CVC)-related complications.

Results

Of the 174 venous accesses placed, 108 were CVCs. 27 (25.0%) catheter tip cultures (CTC) were positive; 12 (11.1%) were catheter-related blood stream infections (CRBSI). Acinetobacter baumannii was the most prominent bacterial infection for both CTC- (55.56%) and CRBSI- (75.00%) positive catheters. CTC- and CRBSI-positive rates were higher during the emergency stage, and both dropped rapidly after reform measures (chi-square test, p = 0.003), and all were negative after the no. 8 catheters. Accumulative regression results indicated that total body surface area burned (TBSA), number of catheters, days of indwelling, and bloodstream infections were independently associated with CTC results, while gender and number of catheters were independently associated with CRBSI results. 1 femur vein thrombosis was detected and cured.

Conclusions

Bedside ultrasound and professional IV team for CVC management are pivotal for massive burn victims. Their intervention helps control CVC-related infections and other complications. A. baumannii was the most frequent bacterial infection found in both CTC- and CRBSI-positive catheters. Several most important factors associated with catheter-related infections were concluded. This information alerts us to watch for patients with such warning factors.
Parenteral Nutrition Solution in Cerebrospinal Fluid in Preterm Newborn – a Case Report and Review of the Literature
Authors: Lachowska Monika , Lachowski Krzysztof , Królak-Olejnik Barbara
Published: April 2016

Introduction

Percutaneously inserted central venous catheters (epicutaneo-cava-catheter - ECC) are widely used in neonatal intensive care, facilitating the parenteral nutrition and the treatment of critically ill newborns. This invasive procedure is regarded as safe and associated with low complication rate. Possible life-threatening complications may result from malpositioning of ECC. Paraspinal misplacement of ECC is one of the most serious complications.

Case Presentation

The authors report a case of misplacement of ECC inserted via left saphenous vein for intravenous feeding. A plane radiograph performed after the procedure showed the line tip at L3-L4 level, supposed to indicate location of the catheter in the vena cava inferior. Three days later, the infant developed neurologic symptoms (lethargy, hypotonia, seizures). Lumbar puncture revealed milky fluid containing parenteral nutrition solution. The infusion was stopped. X-ray with contrast showed the catheterization of the left ascending lumbar vein draining the vertebral venous plexuses. The contrast was highlighting the epidural space. The line was immediately removed resulting in improvement in patient's condition and resolution of all neurological symptoms. There was no sequela of this infiltration and the baby had an uneventful recovery. Follow-up at the age of 12 months showed normal development.

Conclusions

A percutaneous catheter inserted via a lower limb may inadvertently enter the ascending lumbar vein. As previously reported, a catheter inserted via the left lower limb is a risk factor of this malposition. The life-threatening complications may be avoided by careful verification of ECC position (lateral x-ray, contrast examination). Plain radiography alone may not be sufficient for tip localization.
Unusual Cardiac Metastasis of Uterine Leiomyosarcoma: Case Report and Literature Review
Authors: Artioli Grazia , Borgato Lucia , Calamelli Sara , Azzarello Giuseppe
Published: April 2016

Background

Uterine leiomyosarcoma (LMS) is a rare malignancy of mesenchymal tissues and in advanced stages its prognosis is very poor. Surgery followed by radiotherapy and/or chemotherapy is the treatment of choice for advanced disease. Cardiac metastases are very uncommon and only a few cases have been described to date.

Case

A 55-year-old woman was referred to our center for a uterine LMS with lung metastases at diagnosis. After 3 lines of chemotherapy for persistent lung disease, CT scan showed suspected thrombosis in the right pulmonary vein, along with disease progression in the lungs. The patient started treatment with low-molecular-weight heparin and a fourth line of chemotherapy. After 3 months of therapy, a new CT scan showed a larger thrombus and she underwent a cardiology visit that revealed an intracardiac mass. Submitting the patient to palliative surgery or radiation therapy was not possible because of the aggressiveness of the lung metastases, so she continued chemotherapy, resulting in disease stabilization.

Conclusions

Surgery is the best option for intracardiac dissemination of uterine LMS, but when this is not possible based on the performance status of the patient and spread of the disease, the combination of chemotherapy and radiotherapy seems to be the best option according to the literature. In our case we treated the patient only with chemotherapy.

“O mais importante é que a outra pessoa possa te perceber forte”: narrativas de superação em término de relacionamento enquanto performance de si no Facebook
Authors: Brandão Polivanov Beatriz , Rodríguez Santos Deborah
Published: April 2016

Os sites de redes sociais têm se convertido em importantes plataformas de socialização e performance de si na recente década, transformando e ressignificando tensões entre as esferas do público e privado. Eles passaram a ter uma presença significativa na vida cotidiana dos sujeitos, nos modos de eles se autoapresentarem e lidarem com seus conflitos emocionais, usando-as como vias de expressão. O artigo tem como objetivo discutir, a partir do caso de uma jovem cujo casamento terminou, como sujeitos que se encontram em situação de fim de relacionamento amoroso se apropriam do Facebook para construírem novas narrativas de si. Concluímos que seu discurso – entendido enquanto ato performático – remete diretamente à ideia de superação e que a plataforma parece auxiliar no processo de lidar com a dor da separação amorosa, ao mesmo tempo em que foi apontada como causadora da mesma.

Estereótipo na construção da identidade feminina – Dilma Rousseff em seu primeiro mandato
Authors: Martins Ferreira Dina Maria , Pereira Valente Dulce
Published: April 2016

Neste artigo, buscamos analisar a identidade feminina em discursos de Dilma Rousseff, primeiro mandato, tendo em vista, de um lado, os estereótipos históricos da “feminilidade” que valorizam a falocracia, e, de outro, posições de “feminilitude” que valorizam a práxis do feminino, em posição feminista. Para tal, são levantados sentidos linguístico-discursivos com vistas não somente à reprodução de estereótipos históricos, mas também à contestação e ressignificação destes. Nossa análise discursiva prioriza macro-categorias: ethos discursivo, feminilidade e “feminilitude”, cujo propósito é identificar os performativos identitários da “feminilitude”, tais como legitimação e resistência frente a uma ordem social histórica falocrática. E diante desta trincheira, um ethos discursivo se configura por micro-categorias: ruptura, identificação, agenciamento, empoderamento e contestação.
A Renascença e a tecnologia/Renaissance and Technology

Published: April 2016

Os estudos da perspectiva na pintura renascentista, por Leon Battista Alberti e Leonardo Da Vinci, foram um grande avanço técnico para a representação da realidade. As pesquisas do matemático italiano Fibonacci, no século XIII, revelaram que a natureza se organiza em torno de sequências numéricas, indicando uma proporção equilibrada que tem como produto, para o olhar humano, a sensação de beleza, simetria, perfeição. Chamada de “Proporção Áurea” ou “Divina Proporção”. Essa descoberta matemática trouxe à arte todo um conhecimento articulado com a ciência para manipular sentidos e criar a ilusão da terceira dimensão no plano bidimensional do quadro, a profundidade [...].

Por meio de levantamento bibliográfico, de entrevistas com profissionais do UOL TAB, nova seção multimídia do portal UOL e da análise de conteúdo das 30 primeiras edições da referida publicação, este artigo apresenta um estudo sobre a prática do jornalismo multimídia, em que um mesmo profissional produz material em diferentes formatos. Para reflexão sobre o tema, propõe-se uma metáfora baseada no universo dos quadrinhos da DC Comics: no papel do Super-homem, apontamos o profissional desejado por empresários e gestores de comunicação, um superjornalista que produza sozinho para diferentes plataformas com a mesma competência; enquanto a imagem do Batman é associada ao profissional que faz parte de equipes integradas e polivalentes, onde treinamento e parcerias são palavras de ordem.
Da imagem ao processo: a produção e a fruição fotográfica no Arquivo Pedro Meyer
Authors: Santos Ana Carolina Lima
Published: April 2016

O Arquivo Pedro Meyer é uma plataforma digital na qual todo o trabalho fotográfico do artista, além de textos e vídeos sobre ele, está disponível sem qualquer filtro do produtor. O presente artigo se propõe a apresentar esse banco de dados bem como a refletir sobre as implicações que ele traz para a circulação, a difusão e a recepção das imagens de Meyer. Por meio de análises documentais e pesquisas bibliográficas, compreende-se que, ao tornar visíveis seus métodos de produção, o fotógrafo revela uma forma autêntica de lidar como sua criação, entendida não como produto final, mas como algo inacabado e incompleto. Além disso, na medida em que dá ao espectador a chance de entrar nos bastidores de sua obra, olhando-a ‘de dentro’, Meyer permite que ele também passe a entendê-la reintegrada e ressignificada pelos seus processos de fabricação.

Este artículo trata de explicar un desenlace político inesperado: ¿por qué una inmensa mayoría de procuradores franquistas votó a favor de la Ley para la Reforma Política, la cual suponía su propia muerte política? A partir del concepto de «herestética», el artículo analiza las maniobras estratégicas llevadas a cabo por Torcuato Fernández- Miranda, el presidente de las Cortes franquistas, que garantizaron que la Ley se aprobase. Un análisis temático de los tres días de discusión de la Ley en el pleno de las Cortes revela la importancia de la manera en la que se planteó y se determinó la dimensionalidad de esta Ley, lo que debe considerarse como una significante maniobra «herestética» en una situación de transición en la que la necesidad de mantener las apariencias, es decir, de «vestir el muñeco», era de vital importancia.
Ciudadanía, políticos y expertos en la toma de decisiones políticas la percepción de las cualidades de los actores políticos importan

¿Qué factores explican que la ciudadanía prefiera políticos, ciudadanos o expertos en la toma de decisiones políticas? Este artículo demuestra que la falta de apoyo al sistema político desempeña un papel relevante. A su vez, encontramos que la valoración que hace la ciudadanía sobre las cualidades morales y técnicas de los actores tradicionales en democracia (élite política y ciudadanía) ayuda a perfilar mejor la naturaleza de sus preferencias. A partir del análisis de los datos de una encuesta del CIS del año 2011, mostramos que los factores mencionados son relevantes para entender cómo se vertebran las preferencias ciudadanas sobre quién debe tomar las decisiones políticas en democracia. A su vez, nuestros resultados sostienen algunos de los argumentos de Hibbing y Theiss-Morse, mientras que otros deben ser revisados.
The Relationship between Human Resource Management Ambidexterity and Talent Management: The Moderating Role of Electronic Human Resource Management
Authors: AlKerdawy Mostafa Mohamed Ahmed
Published: April 2016

This study investigates the moderating role of electronic human resource management (e-HRM) in the relationship between human resource management ambidexterity (HRMA) and talent management (TM) using data collected from 430 managers working in 10 international banks in Egypt. e-HRM was found to be an important moderator of the relationship between HRMA and TM. The more dependence on e-HRM in executing human resource policies in banks, the greater influence of HRMA on TM. The results referred also a positive and significant influence of both HRMA and e-HRM on TM. This study concludes by discussing managerial implications and the limitations should be addressed in future research.

The aim of this study is to examine the relationship between working capital management and corporate performance for non-financial firms quoted in Borsa İstanbul for the period 2009-2014. The working capital investment decisions of the firms are utmost important since firms can continue their operations without discontinuance, raise their value and reduce risks as long as working capital level is attentively administered. Our research contributes to the working capital literature by investigating the non-linear relation between net trade cycle (NTC) and firm performance, utilising contemporary data and using system Panel GMM method. Our results indicate that there is a non-linear relationship between NTC and corporate performance. This means that there is an optimal NTC value where firm value is maximised. At this optimal working capital level, costs and advantages are poised. This implies that corporate executives should carefully manage their working capital investment and strive to be close to the optimal level as much as possible.

Aquatic vegetation is a potential source of organic matter and nutrients for crop production and soil sustainability. However, its high water content and presence of toxic compounds have been major deterrents for commercial application. This split-pot study evaluated the application of Pistia stratiotes (PS) (water lettuce) and Lyngbya wollei (LW) (filamentous cyanobacteria) to grow rice and sorghum. The aquatic vegetation was applied as dried and composted amendments on sandy (<3% organic matter) and muck (>80% organic matter) soils. A completely randomized split-pot design evaluated the effect of the amendments on root dry weight (RDW), shoot dry weight (SDW), and nutrient content of above ground biomass. The application of dried PS and LW on sandy soil produced larger and heavier sorghum shoots than those grown under composted treatments. Soil type was not a determinant factor of plant nutrient content: total Kjeldahl nitrogen, phosphorus, potassium and silicon. Shoot dry weight of rice grown on sandy soils was significantly greater than grown on muck soils using dried LW and composted LW treatments. The allelopathic effects of PS and LW were more pronounced on sandy soil compared to muck soil, indicating the potential application for using aquatic vegetation as a soil amendment on sandy soil in the future.

Published: April 2016

Most water distribution systems in the United States are designed as looped systems in order to allow multiple pathways for delivery of water to customers. However, these designs also have the negative consequence that, if the system is contaminated, the contamination may travel widely through the system and have widespread impacts. In this article, an alternative design concept is suggested based on the creation of distribution blocks that subdivide and isolate the system so as to limit contaminant movement. A model‐based case study involving a large distribution system was used to evaluate the effectiveness of the distribution block concept. A comparison of the original looped system and the redesigned system also included the following other performance indicators: water age, reliability, and fire flow performance. The analysis showed that for this system, there was a very significant decrease in the water security vulnerability impacts with minimal effects on the other performance indicators.
Select forelimb muscles have evolved superfast contractile speed to support acrobatic social displays

Published: April 2016

Many species perform rapid limb movements as part of their elaborate courtship displays. However, because muscle performance is constrained by trade-offs between contraction speed and force, it is unclear how animals evolve the ability to produce both unusually fast appendage movement and limb force needed for locomotion. To address this issue, we compare the twitch speeds of forelimb muscles in a group of volant passerine birds, which produce different courtship displays. Our results show that the two taxa that perform exceptionally fast wing displays have evolved 'superfast' contractile kinetics in their main humeral retractor muscle. By contrast, the two muscles that generate the majority of aerodynamic force for flight show unmodified contractile kinetics. Altogether, these results suggest that muscle-specific adaptations in contractile speed allow certain birds to circumvent the intrinsic trade-off between muscular speed and force, and thereby use their forelimbs for both rapid gestural displays and powered locomotion.
FOVEA: a new program to standardize the measurement of foveal pit morphology

Published: April 2016

The fovea is one of the most studied retinal specializations in vertebrates, which consists of an invagination of the retinal tissue with high packing of cone photoreceptors, leading to high visual resolution. Between species, foveae differ morphologically in the depth and width of the foveal pit and the steepness of the foveal walls, which could influence visual perception. However, there is no standardized methodology to measure the contour of the foveal pit across species. We present here FOVEA, a program for the quantification of foveal parameters (width, depth, slope of foveal pit) using images from histological cross-sections or optical coherence tomography (OCT). FOVEA is based on a new algorithm to detect the inner retina contour based on the color variation of the image. We evaluated FOVEA by comparing the fovea morphology of two Passerine birds based on histological cross-sections and its performance with data from previously published OCT images. FOVEA detected differences between species and its output was not significantly different from previous estimates using OCT software. FOVEA can be used for comparative studies to better understand the evolution of the fovea morphology in vertebrates as well as for diagnostic purposes in veterinary pathology. FOVEA is freely available for academic use and can be downloaded at:http://estebanfj.bio.purdue.edu/fovea.
