Análisis sociolingüístico: actitudes y empleo de anglicismos en San Juan
Authors: Sanou Rosa , Albiñana Graciela , Galli Graciela , Castañeda Claudia 
Published: December 2017

En las últimas décadas, se ha incrementado notablemente un fenómeno lingüístico–cultural de relevancia: la difusión global del inglés —convertido en lingua franca o lengua internacional— y su fuerte incidencia en otras lenguas, fundamentalmente en lo relacionado a su léxico. Las razones que se esgrimen para explicar este fenómeno son diversas, desde históricas, políticas y económicas, hasta lingüísticas. En este trabajo, exponemos resultados de estudios sobre préstamos ingleses que hemos llevado a cabo en San Juan, en los últimos años, en el marco de la Sociolingüística; en este sentido, nuestra investigación comparte intereses con el Variacionismo y con la Sociología del Lenguaje. En particular, exploramos las actitudes lingüísticas de los sanjuaninos ante los préstamos ingleses, así como su empleo en esa comunidad.Al respecto, examinamos la influencia de factores sociales en sus realizaciones y las áreas temáticas en que se recurre a ellos con más frecuencia; además, calculamos el índice de densidad de uso de anglicismos, y la proporción de réstamos necesarios e innecesarios que se registran tanto en mensajes auténticos publicados en Facebook, como en artículos de la revista Rumbos. El objetivo final es encontrar las motivaciones socioculturales que impulsan el empleo de estas voces inglesas.
ReCache

As data continues to be generated at exponentially growing rates in heterogeneous formats, fast analytics to extract meaningful information is becoming increasingly important. Systems widely use in-memory caching as one of their primary techniques to speed up data analytics. However, caches in data analytics systems cannot rely on simple caching policies and a fixed data layout to achieve good performance. Different datasets and workloads require different layouts and policies to achieve optimal performance.
This paper presents ReCache, a cache-based performance accelerator that is reactive to the cost and heterogeneity of diverse raw data formats. Using timing measurements of caching operations and selection operators in a query plan, ReCache accounts for the widely varying costs of reading, parsing, and caching data in nested and tabular formats. Combining these measurements with information about frequently accessed data fields in the workload, ReCache automatically decides whether a nested or relational column-oriented layout would lead to better query performance. Furthermore, ReCache keeps track of commonly utilized operators to make informed cache admission and eviction decisions. Experiments on synthetic and real-world datasets show that our caching techniques decrease caching overhead for individual queries by an average of 59%. Furthermore, over the entire workload, ReCache reduces execution time by 19-75% compared to existing techniques.

ALTHOUGH THIS SHIFT IS LOGICALLY BASED ON THE POTENTIAL BENEFITS THE TYPE OF TRAINING CAN PROVIDE, THERE IS LIMITED RESEARCH EVIDENCE SUPPORTING THE POTENTIAL BENEFITS WEIGHTLIFTING MOVEMENTS MAY PROVIDE TO SPRINT PERFORMANCE. THE PURPOSE OF THIS ARTICLE IS TO REVIEW THE AVAILABLE SCIENTIFIC RESEARCH, EXAMINING THE IMPACT OF WEIGHTLIFTING-BASED TRAINING ON SPRINT PERFORMANCE.
The Magnitude of Trial-By-Trial Neural Variability Is Reproducible over Time and across Tasks in Humans
Authors: Arazi Ayelet , Gonen-Yaacovi Gil , Dinstein Ilan 
Published: December 2017

AbstractNumerous studies have shown that neural activity in sensory cortices is remarkably variable over time and across trials even when subjects are presented with an identical repeating stimulus or task. This trial-by-trial neural variability is relatively large in the prestimulus period and considerably smaller (quenched) following stimulus presentation. Previous studies have suggested that the magnitude of neural variability affects behavior such that perceptual performance is better on trials and in individuals where variability quenching is larger. To what degree are neural variability magnitudes of individual subjects flexible or static? Here, we used EEG recordings from adult humans to demonstrate that neural variability magnitudes in visual cortex are remarkably consistent across different tasks and recording sessions. While magnitudes of neural variability differed dramatically across individual subjects, they were surprisingly stable across four tasks with different stimuli, temporal structures, and attentional/cognitive demands as well as across experimental sessions separated by one year. These experiments reveal that, in adults, neural variability magnitudes are mostly solidified individual characteristics that change little with task or time, and are likely to predispose individual subjects to exhibit distinct behavioral capabilities.

ABSTRACT
Pineapple is one of the commodities origin of Riau Province. Each year the pineapple increases with the increasing production of pineapple so the waste generated will increase. In pineapple leaf waste is suspected of alkaloid compounds that can kill the mosquito larvae Culex Sp. The mosquitoes belonging to the genus Culex are known as arbovirus-transmitting vectors, elephant leg fever, and malaria in poultry. Insect control is generally done using synthetic pesticides. The use of synthetic chemicals is very dangerous for exposed users. The purpose of this study was to determine the effectiveness of pineapple ethanol extract and to determine the number of dead larvae by determining the best concentration of pineapple ethanol extract (Ananascomosus L.) on culex mosquito larvae Sp. This research is experimental laboratory, which is examining about mortality test of Culex sp. Mosquito larvae after administration of pineapple ethanol extract (Ananascomosus L.). The results showed that pineapple ethanol extract can be proven at concentration level of 1% mosquito larvae mortality rate has reached 72,5%. While at 4% concentration has been able to kill larvae of 97.5%.

Synthesis of a Time History Based on the Sine-on-Random Prediction Methodology Defined in MIL-STD-810 Method 519
Authors: Hale Michael T. 
Published: December 2017

Abstract
Method 519.7, Annex D of MIL-STD-810G, Environmental Engineering Considerations and Laboratory Tests, Change Notice 1 (MIL-STD-810G/CN1) outlines a prediction methodology for establishing a sine-on-random (SoR) structured spectrum that is intended to be representative of gunfire for use in cases in which there is an absence of field data. From that spectrum, the ramp modulated pulse (RMP) technique is proposed as a methodology to synthesize a time history with temporal characteristics that more realistically represent the temporal characteristics of gunfire than that of a SoR time history synthesized via classical SoR generation techniques. This paper provides an alternate technique to the RMP methodology presented in Method 519. The alternate technique is based on normalized exponentially weighted (NEW) time history generated via classical time domain techniques for a SoR vibration test. An outline of the NEW technique and an associated example are provided.
Consumo cultural y el papel de los medios en el control social
Authors: Castaño Estrada Juan Sebastian 
Published: December 2017

La economía mundial conlleva nuevas formas de relación en los campos de la producción, la distribución y consumo, relaciones que obligan a la modernización e introducción de transformaciones en las esferas económica, política y sociocultural. Hoy es posible percibir un enfrentamiento que contrapone lo global a lo local, los medios y sus productos de consumo cultural, que moldean la identidad social. Lo que obliga a los medios, a saber qué conoce o sabe la audiencia para descubrir en dónde comienza la información comprensible y qué capacidad de aprender o comprender posee. De ahí el papel del periodismo enfocado hacia la paz sin establecer límites, encontrar causas y soluciones, en la tradición y el conocimiento, la búsqueda de la humanización de sus actores y estudiar cómo funciona la democracia para fortalecerla, que desde el control social, debe conocer las reglas, para respetarlas y hacerlas cumplir.
El lugar del centro comercial en Cali: el caso del Parque comercial Río Cauca y Unicentro
Authors: Mesa Juan David 
Published: December 2017

A partir de los años setenta en Cali el comercio se comenzó a trasladar del centro de la ciudad a los centros comerciales. En ese sentido, las dinámicas de interacción usuario-consumo se transformaron por completo, posibilitando que los compradores pudieran encontrar “todo” en un mismo espacio. De ese modo, autores como Vásquez (2001) han catalogado estos centros comerciales como no-lugares, partiendo de un supuesto que concibe que en estos espacios no es posible la creación y estructuración de vínculos duraderos. Por todo esto, un aspecto fundamental en este artículo radica en cuestionar ese planteamiento que caracteriza a los centros comerciales como no-Lugares, proponiendo, en contraste, que se han ido diversificando y transformando de tal modo que en la actualidad se constituyen como Lugares en donde se construyen sujetos particulares de consumo, en este caso jóvenes: agentes de interés para el presente estudio. Para tal reflexión, será primordial analizar dos centros comerciales para contrastar las formas de apropiación espacial por parte de los jóvenes: Parque comercial río Cauca y Unicentro.

A dynamic path planning method for wheeled mobile robots (Dyna-bug).
Authors: Karakaya Suat , Kucukyildiz Gurkan , Ocak Hasan 
Published: December 2017

Abstract

In this study, a hybrid path-planning scheme is presented. The main contribution of this paper is merging the static grid costs of the global map and the immediate environmental structure of the local map. The stationary condition of the map and the instant local goal is weighted by certain coefficients in order to determine the next move of the wheeled mobile robot (WMR). Thus, the cost function is defined in terms of the grid costs and the dynamic parameters. The main assumption is that the WMR on which this scheme is executed must be equipped with a field scanning sensor. The sensor readings in each processing cycle are pre-processed before plugging in the cost function. The passages in the local map are extracted from the sensor data, then the optimal collision-free point lying on the passages is obtained via the cost function.
Keywords: Path planning, collision avoidance, mobile robot.
An Unusual Case of an Intra-Articular Osseous Fragment Associated with a Medial Collateral Ligament Femoral Avulsion Fracture in an Adult
Authors: McCarthy Meagan M. , Covey Dana C. 
Published: December 2017

Case:
The medial collateral ligament (MCL) is the most commonly injured ligament of the knee; however, to our knowledge, avulsion fractures of the MCL resulting in an intra-articular fragment have not been reported. We present the case of a 55-year-old woman with a posterior cruciate ligament avulsion fracture and an MCL avulsion fracture with an intra-articular bony fragment.

Conclusion:
Patients who sustain trauma to the knee should be carefully evaluated for ligamentous avulsion injuries. Avulsion fractures in adults represent substantial traumatic injuries, and associated injuries should be suspected. While the MCL is an extracapsular structure, this case report demonstrates that the MCL femoral-sided osseous attachment can displace intra-articularly.
Controversies Surrounding the Management of the Isolated Type-II Radial-Head Fracture

Published: December 2017

* The ideal management of the isolated Mason type-II radial-head fracture is controversial, with studies supporting both nonoperative and operative management.* Inherent controversy remains in the precise definition of the Mason type-II injury and the degree of displacement considered acceptable for nonoperative treatment.* The limitations of current studies include their retrospective nature, lack of adequate controls, insufficient power, uncertain pre-injury functional scores, heterogeneous grouping of radial-head fractures, and variability in fixation techniques.* The design of future comparative studies may consider a suitably powered and controlled prospective study, utilizing a consistent fixation technique, performed at a high-volume center of excellence or at multiple sites.* The impact of patient factors on clinical outcomes warrants further exploration, and future research may consider focusing on potential approaches to modifiable risk factors.
Joint Optimization of Economic Project Life and Well Controls
Authors: Shirangi Mehrdad G. , Volkov Oleg , Durlofsky Louis J. 
Published: December 2017

Summary
A new methodology for the joint optimization of optimal economic project life (EPL) and time-varying well controls is introduced. The procedure enables the maximization of net present value (NPV) subject to satisfaction of a specified modified internal rate of return (MIRR). Knowledge of the economic project life enables the operator to plan for infill drilling or some other type of field development in the case that the lease/contract duration is longer than the optimal project life. This will enable NPV to be maximized, and the hurdle rate to be honored, over the entire duration of the lease. The optimization is formulated as a nested procedure in which economic project life is optimized in the outer loop, and the associated well settings [time-varying bottomhole pressures (BHPs) in the cases considered] are optimized in the inner loop. The inner-loop optimization is accomplished by use of an adjoint-gradient-based approach, while the outer-loop optimization entails an interpolation technique. The successful application of this framework for production optimization for 2D and 3D reservoir models under waterflood is demonstrated. The tradeoff between maximized NPV and rate of return is assessed, as is the impact of discount rate on optimal operations. In the second example, we illustrate the advantages of initiating a new project (that satisfies the hurdle rate) once the EPL is reached. Taken in total, the results in this paper demonstrate the importance of explicitly incorporating both NPV and rate of return in production-optimization formulations.
How A Betawinese Family Implement Politeness in Their Daily Conversation
Authors: Winiharti Menik , Salihah Triana Salihah 
Published: December 2017

Betawi language still exists today. It is particularly used in the suburb area of Jakarta. The typical of this language is changing the suffix /a/ to /e/, as in the words 'siape', 'di mane', 'ade ape', and 'kenape'. The emphasis of suffix /e/ in Betawi language makes this language sound louder or sharper. However, people who are unfamiliar with Betawi ethnic and its language and rarely hear the conversation in Betawinese, usually assume that Betawi language is rude. The paradigm in the society is corroborated by the use of ‘lu’ and 'gua' as the synonyms of 'you' and ‘I’ respectively. In terms of conversation in a Betawinese family, politeness plays a significant role. Every member of the family uses the strategy of politeness. The goals of this study are to find the politeness strategies used by the members of a Betawinese family in their daily conversation. It is also expected to describe the extent to which the family members apply politeness in everyday conversation. The research is conducted by observing the family members when they speak to other members. The data are analyzed based on the speaker and addressee in applying the politeness strategy. The result shows that there are four politeness strategies used: Bald on record, Off record, Positive politeness and Negative politeness. The speakers who have a higher status in the family potentially threaten the 'face' of the hearers who have a lower status. This study has also found that the selection of politeness strategies is determined by two factors; (a) the status of the family members within the family itself and (b) the intensity of inter-speaker meeting. Generally, it is proven that a Betawinese family apply politeness strategies in their daily conversation. Keywords: Politeness strategy, family member, family status, conversation
Simultaneous corrosion control and water quality improvement in water distribution systems
Authors: Bai X. H. , Li R. L. , Zhu H. F. , Chen J. 
Published: December 2017

Abstract
The effects of different dosages of sodium hexametaphosphate and sodium orthophosphate on corrosion inhibition and water quality in two model water distribution systems, and the corrosion inhibition mechanism on pipe walls were investigated. Results show that adding sodium hexametaphosphate and sodium orthophosphate can not only provide a remedy for the damaged cement coating surface, but improve water quality by reducing hardness, turbidity and total iron in cement-coated water distribution systems. The surface exposed to sodium hexametaphosphate was covered by a discontinuous glass-like film, while the other was covered by some phosphate crystals and a thin film. The glass-like film sequestered Ca, Fe and Al on its surface, where calcium hexametaphosphate could be in complex with Fe2O3 or Al2O3 to form the film, while orthophosphate crystals and the thin film were related to Fe and Ca, FePO4 and Ca3(PO4)2 formed and deposited on the surface composing the thin film.

Published: December 2017

Abstract
An eSOS (emergency Sanitation Operation System) Smart Toilet experimental prototype, aimed at improving the provision of safe sanitation in emergency settings, was field tested in a temporary settlement in Tacloban City, Philippines. The design, usage, and user acceptance of the toilet were all evaluated. Quantitative and qualitative data were collected through interviews and questionnaires, supported by the research-team's observations. The survey results indicated that 98% of users (both first-time users and those who tried it a few times) intended to use the toilet again. There were more features that the users liked than disliked. The in-built water supply and user-operated smart toilet features were liked, but the bad smell was disliked. User-operated smart features were an important factor in user acceptance although they were not the main incentives. Key recommendations are to improve the toilet's design to address the odor and cleanliness issues, make handwashing more convenient, and lower the height of the toilet bowl.
Flood control in an urban drainage system using a linear controller

Published: December 2017

Abstract
Effective management of floods in densely populated urban areas poses a great challenge. Computer modeling plays an important role in appropriate management of urban drainage systems. In this study an effort has been made to develop an efficient urban drainage model in which hydraulic results obtained from the developed SWMM model have been linked with a Proportional Integral Derivative (PID) controller for controlling floods. The resulting model can optimize flood levels substantially in urban water bodies and hence can be used as an effective tool to mitigate urban flooding.
