La scolarisation des élèves allophones au collège : étude comparative des modalités d’organisation de quatre dispositifs d’accueil et des effets potentiels sur l’apprentissage du français
Authors: Guedat-Bittighoffer Delphine
Published: December 2015

Cet article présente une étude comparative entre quatre dispositifs de scolarisation des élèves allophones au collège en France. Notre problématique consiste à interroger les éléments facilitateurs de la réussite des élèves allophones parmi lesquels figure la question des modalités d’accueil et de leurs effets sur les apprentissages des élèves. Nous analyserons leur prise en charge au sein des dispositifs cibles à partir de deux focales : l’intérêt intrinsèque de chacun des dispositifs et leur articulation avec « la classe ordinaire ». Les conclusions de cette recherche qualitative qui consiste en des entretiens semi-directifs menés auprès d’élèves allophones et d’enseignants tendent à soutenir que le seul véritable parcours personnalisé et adapté aux apprenants allophones s’inscrit dans les dispositifs d’accueil spécifiques qui leur sont réservés qu’elle qu’ait été leur structure.

Advances in Intramedullary Nailing: Suprapatellar Nailing of Tibial Shaft Fractures in the Semiextended Position
Authors: Zelle Boris A. , Boni Guilherme , Hak David J. , Stahel Philip F.
Published: December 2015

Reamed locked intramedullary nailing remains the standard treatment for displaced tibial shaft fractures. Supra-patellar tibial nailing in the semiextended position has been suggested as a safe and effective surgical technique that allows mitigating certain challenges of the standard subpatellar approach. Suprapatellar nailing seems to facilitate achieving and maintaining fracture reduction, particularly in proximal third tibia fractures. Preliminary investigations have suggested that this technique is associated with a low rate of complications, including a reduced incidence of postoperative anterior knee pain. Further clinical investigations are necessary to establish overall complication rates and long-term subjective outcomes. [

Use of a Bipolar Blood-Sealing System During Total Joint Arthroplasty
Authors: Huang ZeYu , Ma Jun , Shen Bin , Yang Jing , Zhou ZongKe , Kang PengDe , Pei FuXing
Published: December 2015

Educational Objectives

As a result of reading this article, physicians should be able to:

1.

Discuss the available blood-saving strategies for patients treated with total joint arthroplasty (TJA).

2.

State the potential strengths and limitations of using monopolar and bipolar sealer in TJA.

3.

Describe the available evidence regarding monopolar and bipolar sealer use in TJA.

4.

Describe the best situation for use of a bipolar sealer in TJA.

The goal of the clinical use of a bipolar blood-sealing system is to reduce perioperative blood loss in total joint arthroplasty (TJA). This study was performed to determine whether a bipolar sealer is safe and effective in TJA and whether there are any advantages over monopolar sealers. The authors searched electronic databases and reference lists of relevant articles; retrieved all published randomized, controlled trials concerning the subject; and then performed a meta-analysis. Nine clinical trials involving 871 patients were included. The results of the meta-analysis indicate that using a bipolar sealer in TJA could reduce total measured blood loss, intraoperative blood loss, and operative time, which was especially observed in revision TJA for infection and primary total knee arthroplasty without tourniquet use. However, there was no significant difference between the 2 groups in terms of calculated blood loss, hemoglobin decrease, transfusion requirements, length of stay, and complications. The results of the comparison between bipolar and monopolar sealers used in TJA indicate that the routine use of a bipolar sealer for TJA may be of limited benefit except in revision TJA and primary total knee arthroplasty without tourniquet use. In the future, more high-quality randomized, controlled trials are needed to provide robust evidence and confirm the best option. [

Return to Work After Diskogenic Fusion in Workers' Compensation Subjects
Authors: Anderson Joshua T. , Haas Arnold R. , Percy Rick , Woods Stephen T. , Ahn Uri M. , Ahn Nicholas U.
Published: December 2015

Lumbar fusion for degenerative disk disease (DDD) is associated with variable clinical outcomes. Patients with workers' compensation claims often have worse fusion outcomes than the general population. Few studies have evaluated the risk factors for poor outcomes within this clinically distinct population. The goal of this study was to identify preoperative predictors of return to work status after fusion for DDD in a workers' compensation setting. The authors used
International Classification of Diseases, Ninth Revision
(ICD-9), diagnosis and Current Procedural Terminology (CPT) procedural codes to identify 1037 subjects from the Ohio Bureau of Workers' Compensation database who underwent fusion for DDD between 1993 and 2013. Of these subjects, 23.2% (n=241) made a sustained return to work within 2 years after fusion. To identify preoperative predictors of postoperative return to work status, the authors used multivariate logistic regression analysis, adjusting for many important covariates. These included prolonged time out of work (
P
<.001; odds ratio [OR], 0.24), psychiatric history (
P
<.001; OR, 0.14), prolonged use of opioid analgesics (
P
<.001; OR, 0.46), male sex (
P
=.014; OR, 0.65), and legal representation (
P
=.042; OR, 0.67). The return to work rates associated with these risk factors were 10.4%, 2.0%, 11.9%, 21.1%, and 20.7%, respectively. Of the study subjects, 76.8% (n=796) did not return to work and had considerably worse postoperative outcomes, highlighted by chronic opioid dependence and high rates of failed back syndrome, additional surgery, and new psychiatric comorbidity. The low return to work rates and other generally poor outcomes reported in this study may indicate a more limited role for lumbar fusion among patients with DDD who have workers' compensation claims. More studies are needed to determine whether fusion for DDD can improve function and quality of life in these patients. [

The beauty of landforms
Authors: Smrekar Aleš , Polajnar Horvat Katarina , Erhartič Bojan
Published: December 2015

This article determines which landforms attract people the most and whether one can speak of collective patterns in the aesthetic evaluation of a landscape. It therefore concerns enjoying the beauty offered by a more or less reshaped natural environment. This study is based on the Triglav Lakes Valley (Dolina Triglavskih jezer) in Slovenia which, due to the few man-made changes introduced there, includes hardly any anthropogenic “unnecessary noise.” The online survey included more than six hundred people and used photos of various landforms. Lakes were found to be the most attractive to the respondents, and fractured rock areas were the least attractive.
Interchange nodes between suburban and urban public transport: A case study of the Czech Republic
Authors: Ivan Igor
Published: December 2015

This paper presents a methodology for localizing theoretical interchange nodes used for interchange between suburban and urban public transport in thirteen regional capitals in the Czech Republic. This methodology is based on the use of current timetables and simulation of more than 2,500 public transport connections between selected surrounding municipalities with significant commuter flows and randomly selected urban public transport stops within the regional capitals. The second part of the paper focuses on particular interchange nodes. Regional capitals are divided into groups according to the level of centrality of interchange nodes and the prevailing orientation of the transport mode. The article also analyzes the time stability of localized interchange nodes.

Authors: Smrekar Aleš , Šmid Hribar Mateja , Erhartič Bojan
Published: December 2015

Green areas and especially their distribution and composition are the key factor that makes urban people’s lives more comfortable and healthier. Even though Ljubljana residents also have many other green areas at their disposal in their immediate vicinity, the area of Rožnik Hill and Tivoli Park as an urban forest with dispersed park features continues to be the most popular recreational destination, with roughly 1,750,000 visits per year. In 1984 it was designated a protected landscape area through an ordinance. In the past decades, a number of conflicts have arisen in this area between various stakeholders, such as landowners, park users, and specialist services, which is why these types of areas require careful and prudent management.
Le jeu vidéo comme pratique discréditable
Authors: Gerber David
Published: December 2015

Partant du constat que la pratique des jeux vidéo a un statut incertain en termes de valeur culturelle et d’acceptabilité sociale, cet article esquisse les manières dont les joueurs de jeux vidéo se confrontent à des contraintes normatives et négocient les conditions d’acceptabilité de leur pratique. L’analyse de récits biographiques de 28 joueurs aux carrières ludiques variées permet de décrire comment se manifeste l’inacceptabilité de la pratique du jeu vidéo, puis de dresser un inventaire des positionnements adoptés face à la menace de discrédit : du simple évitement d’un stigmate jusqu’à l’ambition de transformer la place du jeu vidéo dans la société. Les joueurs n’ont pas les mêmes ressources pour rendre leur pratique acceptable, et nos résultats soulignent le poids de valeurs familiales intériorisées, du capital culturel et vidéoludique, ainsi que l’importance particulière de la position du joueur dans le parcours de vie.

Individual Differences, Learning Opportunities and Learning Outcomes, Digital Equity
Authors: Sedivy-Benton Amy L.
Published: December 2015

Information and communication technologies are prevalent in almost every aspect of our world, ranging from their presence in schools to even being used by a passenger on a bus. Unfortunately, not all individuals have the same opportunity or access to these technologies, especially children who are still receiving their education. This limited opportunity creates a disparity between those who have access and those who do not, the impact goes far beyond just securing the latest device, rather it can impact their future as students. With limited access many of these children may not be career ready. Policymakers as well as institutions of education need to pay attention to the growth of these technologies as well as the infrastructure that is in place to ensure equal opportunities for all. This chapter provides an overview of what is commonly discussed when talking about digital equity and digital access in PK-12 schools. Examples of teacher implications and resources are provided, and a call for a shift in culture is present. The chapter concludes with recommendations for schools and policy-makers to consider when they begin to address the technological needs in order to prepare students for the future.
Retaining Disciplinary Talents as Informal Learning Outcomes in the Digital Age
Authors: Huang Wen-Hao David , Oh Eunjung
Published: December 2015

Considering the national need for developing a variety of professional talents through higher education, this chapter proposes an exploratory conceptual framework, to allow educators and parents to harness informal learning opportunities afforded by virtually endless resources on the Internet, in order to engage undergraduate students with necessary career decision-making processes early on in their college experience. The thesis of this chapter asserts that we must consider students' career decision-making processes as a relevant higher education learning outcome. The proposed Digital Informal Learning Resources for Career Decision-Making (DILR-CDM) framework is grounded in the Social Cognitive Career Theory and the Self-Determination Theory to identify attributes of informal learning resources manifested by digital game-based environments and social media environments. These attributes, in turn, afford informal learning opportunities to scaffold and facilitate career decision-making processes among undergraduate students.
Identifying Effective Talent Management Policies and Practices in the United Arab Emirates (UAE)
Authors: Vassilopoulou Joana , Tatli Ahu , Ozbilgin Mustafa , Pinnington Ashly H. , Alshamsi Abdullah Mohammed
Published: December 2015

Talent management is an increasingly popular management approach and academic research field, yet it is understudied in non-western contexts. Understanding the issues of the management of talent is important in the context of the UAE, where talent shortages exist alongside high unemployment of Emirati nationals. Drawing on a larger study titled: ‘Movers and shakers of talent management in the UAE'', this chapter addresses this gap and generates recommendations for policy and decision making in UAE workplaces. We offer a foundation for evidence-based talent management for governmental policy makers and for organisations in the public and private sectors. Particularly, we suggest that focusing on empowerment and employment of Emirati talent is important but insufficient for organisations to tackle the complexity of talent. Legal and voluntary measures should focus on the current dynamics of talent locally and internationally in order to foresee the future of talent needs. This process is called future proofing, which can help organisations to prepare for future talent challenges.
Art, Values, and Conflict Waged in Satirical Cartoons
Authors: Hall Z.
Published: December 2015

The first international art controversy erupted after the publication of satirical cartoons of the Prophet Muhammad in Denmark's Jyllands-Posten in 2005. Unlike prior art controversies, the Muhammad cartoon controversy, as it came to be known, engaged millions of people around the globe. Debates and protests surrounding competing sacrosanct values received massive media attention. As the conflict between Western free speech and 10th anniversary of the September 30 publication of the cartoons approaches, the world mourns the loss of more lives in connection with the continuing controversy. By examining the constellation of speech acts associated with Flemming Rose, Stephane Charbonnier, and Lars Vilks, this chapter examines whether satire is an effective rhetorical device for resolving disagreements involving conflicting sacrosanct values, and if and how it ameliorates or contributes to conflict in increasingly multi-religious, multiethnic, and multicultural societies.

Published: December 2015

Globalization has placed modern organizations in tremendous competition locally and regionally across borders; thus, the ultimate goal of every organization is the same which is profitable survival. In order to make sure that this profitable survival goal does not come at the cost of harming others, guiding principles are needed to bring goodness and fairness for the stakeholders' interests. This paves the way for designing, implementing and adopting ethical principles in the organization to keep competition fair and just. This chapter highlights the significance of adopting ethical practices in organizations at the threshold of 21st century and its challenges. It discusses how individual ethics system has been formed which further goes to make a healthy workplace. As religion has always been a source of inspiration for its followers, hence, this chapter attempts to trace ethical inspirations in religious teachings, specifically Islamic work ethics. Recommendations for training and development are provided.
What Matters Most

Published: December 2015

This chapter aims to identify the level of importance of the performance attributes of architects in the project delivery process by using self-evaluation. Good performance is the only insurance that can help construction professionals, such as architects, to survive in the industry. Performance problems during the design process that are experienced by these professionals are the reasons for the drawbacks and deficiencies in construction. The present study proposes 37 performance attributes. The results revealed that understanding the client's objectives is the performance attribute with the highest relative importance index value. The present study recommends for future research on improving the performance assessment in design practice and providing behavior-based feedback to increase feedback accuracy for measuring the performance of architects in the design delivery process needed by the employers in the construction industry.

Published: December 2015

According to World Health Organization, there was increase in the number of people that have access to safe drinking water between 2006 and 2010. Such trends can be countered partly by the use of ceramic water filters that can remove microbial pathogens from water. However, the initial flow rates in such filters are often limited to ranges between 1 and 3 L/hr. The flow rates may vary statistically and decrease with increasing filter use. In this paper, the flow through ceramic water filters is characterized using Darcy’s equation. An effective permeability is obtained for filters with a range of micro-and nanoscale pore sizes. The statistical variations in the flow rates and effective permeabilities are elucidated along with the potency of multiple filter system for scale-up studies in serving a community.

Published: December 2015

In this paper, ductile iron was produced using a rotary furnace. The microstructures of the ductile iron (with and without cyanided coatings) were then characterized using optical microscopy, scanning electron microscopy (SEM) and energy diffraction X-ray spectroscopy (EDS). The surfaces of the ductile iron were then subjected to high temperature carbonitriding using a pack cementation process in which carbon and nitrogen were diffused into the ductile iron from powder mixtures consisting of ground cassava leaves and barium carbonate (BaCO3) energizers. The wear behavior of the coated and uncoated ductile iron was studied using the pin-on-disk method. The wear mechanisms were also elucidated using a combination of SEM and EDS. The mechanisms of wear were also studied using nanoscratch experiments. The resulting wear rates are then compared with those from micron-scale wear tracks obtained from pin-on-disk experiments. The implications of the results are then discussed for the design of wear resistant ductile irons.

A Cascade-Classifier Approach for Fall Detection
Authors: Suardiyana Putra I Putu Edy , Brusey James , Gaura Elena
Published: December 2015

The current machine learning algorithms in fall detection, especially those that use a sliding window, have a high computational cost because they need to compute the features from almost all samples. This computation causes energy drain and means that the associated wearable devices re- quire frequent recharging, making them less usable. This study proposes a cascade approach that reduces the computational cost of the fall detection classifier. To examine this approach, accelerometer data from 48 subjects performing a combination of falls and ordinary behaviour is used to train 3 types of classifier (J48 Decision Tree, Logistic Regression, and Multilayer Perceptron). The results show that the cascade approach significantly reduces the computational cost both for learning the classifier and executing it once learnt. Furthermore, the Multilayer Perceptron achieves the highest performance with precision of 93.5%, recall of 94.2%, and f-measure of 93.5%.

Imágenes 2.5D basadas en información de reflectancia para la interpretación morfológica del patrimonio arquitectónico
Authors: García-Fernández J.
Published: December 2015

La evolución de las técnicas de documentación digital y renderizado ha supuesto un cambio sustancial en la representación y preservación del patrimonio cultural en los últimos 20 años. En el campo de la fotogrametría, las imágenes por transformación de reflectancia (RTI, del inglés Reflectance Transformation Imaging) para la representación interactiva de las propiedades geométricas de superficies, resultan una herramienta eficaz en tareas de interpretación y conservación del patrimonio cultural. La necesidad de unas condiciones de luces y posiciones de cámaras específicas para su generación, han limitado su aplicación en la arqueología de la arquitectura, ciñéndose a objetos de pequeñas dimensiones: artefactos, esculturas, inscripciones, entre otros. El presente estudio propone un nuevo flujo de trabajo que elimine la dependencia a las condiciones externas y la escala, para la interpretación morfológica del patrimonio arquitectónico desde imágenes RTI: partiendo de la reconstrucción virtual tridimensional de escenarios basados en métodos fotogramétricos hasta la generación de imágenes RTI. El flujo será demostrado mediante la representación 2.5D de la topografía interior de los vestigios del Castillo de Villagarcía de Campos en España, para la identificación de trazas históricas no documentadas.

Authors: Ferrelli F. , Bustos M. L. , Huamantinco-Cisneros M. A. , Piccolo M. C.
Published: December 2015

El estudio del clima urbano es relevante para conocer el ambiente donde habita la mayor parte de la población. Las ciudades presentan sectores que incluyen estructuras edilicias, espacios verdes, suelos al descubierto, tránsito vehicular, necesidades calóricas de la ciudad y diferentes coberturas de sombras. Actualmente, el cambio climático y sus efectos sobre las ciudades son temas de gran interés científico. Son escasas las investigaciones que interpretan los cambios térmicos que se producen en el interior de las ciudades debido a la densificación de los edificios y como consecuencia de la variabilidad climática. Por tal motivo, el objetivo de este trabajo fue analizar el comportamiento de la Temperatura de Superficie Terrestre (TST) y su relación con las distintas coberturas del suelo en la ciudad de Bahía Blanca, Argentina. Para ello, se analizaron imágenes satelitales Landsat 5 TM y 7 ETM+ con el método monocanal. Además, se realizó un mapa de coberturas del suelo mediante interpretación visual de imágenes satelitales validado por intervención empírica. Posteriormente, se relacionaron los datos de TST con las coberturas del suelo. En el centro de la ciudad, la TST presentó variaciones espaciales heterogéneas según las estaciones del año y las sombras generadas por los edificios. Los mayores valores de TST se localizaron en la periferia (45,1°C) y en urbano muy disperso (46°C) y el menor en el centro de la ciudad (2°C). Las distintas coberturas del suelo generaron menores fluctuaciones de TST en invierno (>5°C) y las mayores en verano (entre 15 y 25°C).
Peter Jackson
Authors: Leotta Alfio
Published: December 2015

Peter Jackson is one of the most acclaimed and influential contemporary film-makers. This is the first book to combine the examination of Jackson’s career with an in-depth critical analysis of his films, thus providing readers with the most comprehensive study of the New Zealand film-maker’s body of work. The first section of the book concentrates on Jackson’s biography, surveying the evolution of his career from the director of cult slapstick movies such as Meet the Feebles (1989) and Braindead (1992) to an entrepreneur responsible for the foundation of companies such as Wingnut Films and Weta Workshop, and finally to producer and director of mega blockbuster projects such as The Lord of the Rings (2001–2003) and The Hobbit (2012–2013).

The book further examines Jackson’s work at the level of production, reception and textuality, along with key collaborative relationships and significant themes associated with Jackson’s films. The examination of Peter Jackson’s work and career ties into significant academic debates, including the relationship between national cinema and global Hollywood; the global dispersal of film production; the relationship between film authorship and industrial modes of production; the impact of the creative industries on the construction of national identity; and new developments in film technology.
Capsulorhexis Tearing Pattern during Phacoemulsification in Anterior Lenticonus Due to Alport Syndrome
Authors: Boss Joseph D. , McDermott Mark
Published: December 2015

Purpose

To describe the tearing pattern during continuous curvilinear capsulorhexis in a patient with anterior lenticonus due to Alport syndrome.

Methods

A patient with bilateral anterior lenticonus underwent successful bilateral phacoemulsification and implantation of a single-piece intraocular lens.

Results

The capsule tore in an atypical cogwheel-like tearing pattern during capsulorhexis. This tearing pattern likely correlates to the known ultrastructural characteristics of thinning and periodic dehiscence and breaks in the anterior capsule.

Conclusions

Knowing this tearing pattern preoperatively can help to prevent capsule runoff and capsule rupture.

Authors: Leisser Christoph , Hirnschall Nino , Hackl Christoph , Plasenzotti Pia , Findl Oliver
Published: December 2015

Purpose

To evaluate the effect of eplerenone on patients with long-term recurring central serous chorioretinopathy (CSC).

Methods

In this retrospective case series, 11 patients with chronic recurring CSC were included. The main focus was to include patients who had undergone photodynamic therapy (4 patients), had undergone anti–vascular endothelial growth factor treatment (3 patients), or had several episodes of CSC in the past (4 patients) (mean age 60 years; SD 9.7, range 47-76).

Results

Four patients (36.4%) had full resorption of neurosensory detachment under therapy of eplerenone with improvement of vision, while 4 more patients had improvement of vision despite residual edema. Eight patients (73%) had improved visual acuity (VA) at the end of eplerenone therapy, 2 patients had no change in VA, and 1 patient decreased VA. Mean time of treatment was 10.6 ± 9.9 weeks (range 3-38 weeks). All patients showed subretinal deposits, with 6 of them having hyperautofluorescent subretinal deposits.

Conclusions

Eplerenone represents a new treatment option for patients with CSC. Our data indicate a good response in those patients, leading to improvement of VA in 73% of patients.
3-Year Follow-up of a Long-Term Registry-Based Multicentre Study on Vitamin E Diffused Polyethylene in Total Hip Replacement
Authors: Sillesen Nanna H. , Greene Meridith E. , Nebergall Audrey K. , Huddleston James I. , Emerson Roger , Gebuhr Peter , Troelsen Anders , Malchau Henrik
Published: December 2015

Purpose

Preclinical studies of vitamin E diffused highly cross-linked polyethylene (E-XLPE) has shown enhanced mechanical properties with less wear. The purpose of our study was to document the early clinical outcome of E-XLPE to ensure, for the safety of patients, that there are no unforeseen early adverse events from using this new biomaterial.

Methods

The enrolled patients (n = 977) have received either a porous titanium coated or porous plasma sprayed acetabular shell with either a E-XLPE liner or a medium cross-linked (AXL) liner. At each follow-up 5 patient-reported outcome measures (PROMs) were completed: Harris Hip Score, Case Mix Indicator, UCLA Activity Score, SF-36, and EQ-5D. Radiographs were measured for cup and stem position, as well as femoral head penetration into the liner (wear). Postoperative complications and revisions were collected.

Results

At 3 years follow-up, there were 13 revisions due to: 4 periprosthetic fractures; 1 sepsis; 6 instabilities; and 2 implant mismatches at surgery. Wear of the hip implant, calculated by software analysis of pelvis x-rays, from the postoperative interval to 3 years showed a liner penetration rate of 0.027 mm/year for AXL and 0.005 mm/year for E-XLPE with no significant difference between the 2 (p = 0.24). Improvement was seen in all PROMs from the preoperative interval to 3 years after surgery (p<0.0001).

Conclusions

Early follow-up of the E-XLPE and AXL liners show low penetration. PROMs indicate improvement after total hip arthroplasty in functionality and quality of life across the centers. We have not observed any early in vivo adverse effects from diffusing the liners with vitamin E.

Computed Tomography showed quadratus femoris tear with occult underlying ischiofemoral impingement pathology.

Conclusions

Quadratus femoris muscle is a hip external rotator and adductor and is situated along the posterior aspect of the hip joint and its proximity of anatomy with other external rotators leads to diagnostic pitfalls for radiologists. Identification of the exact muscle tear will establish the diagnosis, guide the proper physical therapy and reliably inform the patient what to expect after treatment.
A note on sampling chironomids for RNA-based studies of natural populations that retains critical morphological vouchers
Authors: Krosch Matt N , Bryant Litticia M
Published: December 2015

The rapid uptake of transcriptomic approaches in freshwater ecology has seen a wealth of data produced concerning the ways in which organisms interact with their environment on a molecular level. Typically, such studies focus either at the community level and so don’t require species identifications, or on laboratory strains of known species identity or natural populations of large, easily identifiable taxa. For chironomids, impediments still exist for applying these technologies to natural populations because they are small-bodied and often require time-consuming secondary sorting of stream material and morphological voucher preparation to confirm species diagnosis. These procedures limit the ability to maintain RNA quantity and quality in such organisms because RNA degrades rapidly and gene expression can be altered rapidly in organisms; thereby limiting the inclusion of such taxa in transcriptomic studies. Here, we demonstrate that these limitations can be overcome and outline an optimised protocol for collecting, sorting and preserving chironomid larvae that enables retention of both morphological vouchers and RNA for subsequent transcriptomics purposes. By ensuring that sorting and voucher preparation are completed within <4 hours after collection and that samples are kept cold at all times, we successfully retained both RNA and morphological vouchers from all specimens. Although not prescriptive in specific methodology, we anticipate that this paper will assist in promoting transcriptomic investigations of the sublethal impact on chironomid gene expression of changes to aquatic environments.
Aplicación Integrada para Construcción de PCBs mediante Tecnología CNC y Ajuste Automático a la Superficie
Authors: Ocampo Jared Roberto , Deras Iván De Jesús
Published: December 2015

Uno de los mayores problemas que tienen los alumnos de las carreras del área electromecánica de Unitec es producir sus propios tableros de circuitos impresos (PCB) de manera precisa y segura. Actualmente los estudiantes utilizan la técnica de ataque químico y transferencia de tóner para realizar sus prototipos de PCBs en clases de circuitos eléctricos y electrónica. Sin embargo, esta técnica a pesar de ser de fácil aplicación, es larga y tediosa, produce placas con defectos cuando las pistas son delgadas y es peligrosa por causa del ácido que debe usarse, el cual es nocivo para la salud y el medioambiente. A través de este proyecto se creó un sistema informático integrado que permite hacer uso de una maquina CNC para producir tableros de circuito tomando en consideración la altura de las placas de manera más rápida, con menos defectos de fabricación y sin la necesidad de poner en peligro la salud de los usuarios y de contaminar el medioambiente por el uso de ácidos nocivos.Innovare.

¿Cómo se Reduce el Desempleo?
Authors: Cáceres Luis Rene
Published: December 2015

En este trabajo se estima un modelo con datos-panel anuales de México, Costa Rica, El Salvador, Honduras y Nicaragua, del período 1995-2007 para apreciar las respuestas de la tasa de desempleo a cambios en una serie de variables económicas. El artículo concluye que existen evidencias para argumentar que una reforma fiscal que genere suficientes recursos para cerrar el déficit fiscal e incrementar la inversión pública, redundaría en fortalecer el ahorro nacional y la inversión privada, por lo tanto en aumentar la tasa de crecimiento económico.Innovare.

Fortaleciendo la Motivación Mediante Estrategias de Comprensión Lectora en Estudiantes de Educación Primaria
Authors: Galindo Jessica R. , Martínez Ingrid
Published: December 2015

Uno de los mayores problemas que tienen las escuelas es encontrar métodos que ayuden a sus alumnos a mejorar su aprendizaje y rendimiento académico. El propósito de esta investigación es proponer una forma de ayudar a los estudiantes con pobre rendimiento académico a mejorar sus notas mediante su involucramiento en un programa de lectura independiente significativa. Las hipótesis del estudio son: que la falta de lectura independiente significativa en los alumnos contribuye a su pobre rendimiento académico y que la asimilación de estrategias de comprensión lectora en los alumnos genera motivación hacia la lectura. Para aumentar la comprensión lectora se creó un Programa Instructivo de Lectura (PIL) y se midió la motivación de los estudiantes hacia la lectura antes y después de usar el PIL mediante el uso del Instrumento de Motivacion Intrínseca (IMI), diseñado por Ryan y Deci (2000). Se corroboró que existe una fuerte correlacion entre el rendimiento académico y la lectura independiente significativa, así como que el uso del PIL aumenta el nivel de motivación de los alumnos hacia la lectura independiente.Innovare.

Análisis perceptivo de la gestión turística actual de las MIPYME en la región de San Pedro Sula
Authors: Paredes Heller Juan Jacobo
Published: December 2015

La necesidad de afrontar nuevos retos, además de la globalización, han hecho que las empresas de todo el mundo necesiten ser competitivas. En este contexto se realizó una investigación en las empresas micro, pequeñas y mediana (MIPYME) del rubro hotelero en la ciudad de San Pedro Sula. Se debe entender que la competitividad es un problema nuevo en los países en vías de desarrollo, debido a que cada país enfrenta diferentes desafíos que se acentúan al desconocer el nivel de competitividad. El objetivo general de este trabajo fue determinar la correlación entre las variables: calidad, precio, canal de distribución, servicios y tecnología, con la competitividad del rubro comercial hotelero. En relación con los resultados que se obtuvieron; la calidad, canal de distribución, precio, servicios, y tecnología, tienen un nivel de 75%, 75%, 70%, 79% y 76%, respectivamente, en relación con la competitividad. Concluyendo en que, el nivel de competitividad es regular. Siendo las micro empresas de este rubro, las que resultaron con un bajo nivel: de malo a regular.

Objective: This paper aimed to determine the level of well-being of Police officers and to assess and compare the well-being levels among police officers of low, middle and high ranks. Methods: Data were obtained using a context specific questionnaire that was distributed across the five geographic zones of Malaysia. Results: The results indicate that overall police officers’ well-being is in need of improvement. Low rank officers faced poor work environment, deficient financial security and economic well-being, lack of opportunity for continuing education and career, poor overall physical health and negative political and spiritual well-being. The finding of this study provides the necessary information to develop and implement measures to enhance the current well-being of police officers.
Conceptual Framework for Collaboratively Managing Coupled Human and Natural Systems under Climate Change Uncertainty
Authors: Prato Tony
Published: December 2015

A collaborative decision making (CDM) framework is developed for managing coupled human and natural systems (CHANS) over time when managers are uncertain about one or more drivers of system behavior. The framework incorporates six elements: (1) framing the problem; (2) selecting management objectives; (3) choosing scenarios for future changes in one or more drivers of system behavior; (4) formulating alternative management actions; (5) estimating the values of management objectives and determining their compliance with maximum or minimum acceptable levels; and (6) determining preferred management actions for each driver scenario and time period. Application of the framework is illustrated for a hypothetical case study that determines preferred management actions over time for a highway corridor through a hypothetical national park based on four management objectives: minimizing soil erosion and vegetative losses along hiking trails in the highway corridor; and minimizing traffic congestion on the highway and visitor congestion on hiking trails in the highway corridor. Uncertainty about future visitor use of the highway corridor is taken into account by specifying low, medium, and high visitor use scenarios for the corridor. Preferred management actions for each visitor use scenario within time periods are determined using the fuzzy Technique for Order Preference by Similarity of Ideal Solution to rank management actions for each visitor use scenario. The preferred management action across visitor use scenarios for each time period is determined by applying the minimax regret criterion to maximum loss indices for the preferred management actions for visitor use scenarios.
