Capturing Definitions for a Sustainable Distance Education Ecosystem through an Online Delphi Study
Authors: Gundogan M. Banu , Eby Gulsun , Yuzer T. Volkan
Published: October 2014

In broadest terms, ecology is the scientific study of interactions among organisms and their environment, and ecosystem defines a community of living organisms in conjunction with the nonliving components of their environment interacting as a system. At present, both terms are references of many studies including education; various authors and studies investigating distance education with an ecological perspective refer to the ecosystem concept as frameworks for defining the operational components and processes. Among all these contributions, the concept of “waste,” one of the key concerns of sustainability, seems to be vaguely discussed. Having this as a standpoint, an online Delphi study was carried out in a research project at Anadolu University, Turkey, aiming to define a sustainable distance education ecosystem including the explanation of “waste” with reference to ecosystem definitions. The study was processed online and is explained by both presenting the results and discussing the benefits and also difficulties encountered.
Leveraging Two Computer-Assisted Qualitative Data Analysis Software Packages to Support Discourse Analysis
Authors: Lester Jessica Nina
Published: October 2014

The purpose of this chapter is to illustrate how Computer-Assisted Qualitative Data Analysis Software (CAQDAS) packages, such as ATLAS.ti or Transana, can be used to support the transcription and data analysis process of large interactional data sets – specifically data analyzed from a discourse analysis perspective. Drawing from a larger ethnographic study, in this chapter the author illustrates how carrying out the transcription and analysis process within a CAQDAS package (in this case, Transana and ATLAS.ti) allows for an increase in transparency within the transcription and data analysis process, while also meeting the particular needs of the discourse analyst. By using one particular case/research study, the author demonstrates how CAQDAS packages might function to support a researcher in generating a more systematic and transparent analytical process, specifically during the early stages of the analysis process. The author gives particular attention to interactional data (i.e., 300 hours of video and audio recordings of therapy sessions) collected in a larger study and demonstrates the potential benefits of working across two CAQDAS packages, specifically Transana and ATLAS.ti, to support both the nuanced transcription process and the larger data analysis process.
Practical Wisdom of Tool and Task
Authors: Smith Nancy J , Bhattacharya Kakali
Published: October 2014

The purpose of this chapter is to explain the effective use of digital tools to display and analyze mixed methods data and to identify the challenges and possibilities of doing a qualitatively driven mixed methods study of technology use in education. To frame this chapter, examples from a qualitatively driven mixed methods study of doctoral students, which explored how the use of mobile technology affected engagement in the class experience, are presented. Additionally, the authors discuss the limits, implications, and possibilities of inductively driven mixed methods, while dealing with issues of academic rigor and trustworthiness using Morse and Niehaus's (2009) guidelines for mixed methods research design and the ways in which digital tools enhance rigor and trustworthiness.
Software-Assisted Transcribing for Qualitative Interviews
Authors: Justinia Taghreed
Published: October 2014

This chapter introduces a guide to transcribing qualitative research interviews assisted by digital transcription software. It also provides practical advice on transcribing methods, conventions, and options. It is useful in its exploration of the challenges involved with transcribing, while it offers detailed solutions and advice for the novice researcher. The chapter also addresses key concerns, like the time it takes to transcribe, transcription tools, and digital versus analogue recordings. As a method chapter based on experiences from a case, it takes on a practical approach by demonstrating the benefits of data analysis software packages with examples and screenshots on how to specifically use the software package Express Scribe. The pros and cons of using a transcriptionist are also discussed. A real transcript is presented in the chapter, and the steps involved with developing and formatting it are offered in detail. The guidelines suggested in this chapter are concentrated on the pragmatic hands-on experience of a researcher with examples from a real life large-scale qualitative study based on in-depth interviews. The significance of transcribing within the analytical process and the methodological insights of using Express Scribe eventually emerge as a developing concept from this work.
The Theory and Application of Process Research to the Study of IT Strategy-Making
Authors: Caffrey Eamonn , McDonagh Joe
Published: October 2014

This chapter presents an overview of process research and places a particular emphasis on reviewing the process method. Some insights into the nature of process are presented. The purpose of this chapter is to describe the process method in detail. Some of the methodological challenges involved in conducting process-oriented inquiry are highlighted. Appropriateness of the method to study strategy-related issues is presented which interlocks well with its suitability to investigate issues of interest in relation to IT strategy-making. Application of the process method cycle of research steps is recommended to distil rigorous and relevant theory. Alternative process research sense-making strategies are revealed at a very high-level only. Narrative analysis is presented as a viable sense-making approach to theorize process data and key features of this analytical strategy are revealed. Emerging issues and opportunities that intersect with the IT strategy-making construct are discussed.
Mixed Methods Research Online
Authors: Issa Theodora , Pick David
Published: October 2014

Contributing to the ongoing debate in research on sensitive issues such as business ethics, this chapter provides a discussion of mixed methods research design, examining the processes and challenges of developing and deploying an online survey tool using technology within an interpretive mixed methods design. This chapter provides pointers on how to deploy this approach through technology to research business ethics using the example of researching ethical mindsets and its components, including spirituality and aesthetics. It is found that mixed methods research is an effective approach because it allows often sensitive issues (i.e. business ethics, aesthetics, spirituality) relating to questioning individuals' inner values and ethical propensities, which are usually subtle and difficult to measure and analyze constructs. While this tool was developed in the Australian context, it has the potential to form a foundation for wider examination and research in business ethics. The chapter contributes to the collective discussion of research methods using a framework that has both practical relevance and theoretical rigor.
Integrating Process Inquiry and the Case Method in the Study of Information Systems Failure
Authors: Dempsey Brian , McDonagh Joe
Published: October 2014

This chapter examines the integration of process inquiry and the case method in the study of Information Systems (IS) failure. Having acknowledged the prevalence of IS failure and the need for continued inquiry in this domain, the two predominant methods of inquiry, factor and process studies, are described along with the utility of both methods. The chapter then examines the nature of process inquiry and notes its utility and prevalence in the study of IS phenomena, and its potential applicability for inquiry into IS failure. The case study method is then briefly described along with its potential contribution when combined with process inquiry. The chapter then describes how the case method can provide an overall framework for the conduct of a process inquiry and presents an iterative six-stage research process model based on the case method to assist with the planning, design, preparation, data collection, data analysis, and reporting of findings.

Even though informal learning plays an important role in everyone's life, not everyone is aware of its importance. These informal activities contribute to the development of self-regulated learning that can help productivity in different environments. As this kind of apprentices grow, the need to keep track of this developed knowledge is becoming vital. This paper presents a study on the perception and usage of a tool that would help keeping track of learners' informal learning. This study was conducted both within academic and professional contexts and was developed within the European Commission funded TRAILER project. The contexts were similar regarding the importance and perception of informal learning, but differed concerning tool usage and the usefulness of such a platform. The overall idea of managing one's informal learning was well accepted and welcomed, which validated the emerging need for a tool with this purpose.
A Brief History of Networked Classrooms to 2013
Authors: Abrahamson Louis , Brady Corey
Published: October 2014

When the original work appeared (Abrahamson, 2006), it spoke of a huge burgeoning sense of excitement surrounding networked classrooms and their growing use throughout universities worldwide. Today, the picture is more complex and substantially more interesting. Driving forces, which include growing acceptance of the evolving nature of teaching and learning, high quality experiments showing what works, and a revolution in the capability, cost, and ease of use of technology itself, are changing the world of education. This is evidenced by the dramatic spread of networked classrooms: today almost every K-12 school and 1 in 6 classrooms in the USA have a system. This evolution, and the interwoven forces that have produced it, make an interesting tale. But, perhaps more significant is the future that these events portend. This paper tries to relate the past in order to look toward that future. Beginning with a brief history of early response systems, it takes up the story from the first author's own experience leading a team through hardware barriers, misconceptions about pedagogy, and subsequent classroom successes, to summarize the variety of uses of classroom networks, and how they can lead to improved teaching and learning. It then describes the struggles to evolve the technology from 1st to 2nd generation, and a subsequent nationwide randomized control trial in the teaching of Algebra, using this technology, which yielded significant gains in student learning. Finally, imbedded within the narrative, are growing revelations that show why this is such a potentially important area of study for improving education, and why more powerful types of modern systems appear imminent. (Note: This work is an updated and expanded version of an original book chapter written eight years ago (Abrahamson, 2006). The present paper is still written in the first person as a narrative, although a second author has been added. Where not specifically identified, use of the first person in the narrative still refers to the first author. The work of the second author also uses the first person, but his name is identified where his narrative appears.)
Problems and Possibilities to Enhance Non-Local Work-Integrated Learning Experience for Postgraduate Design Research
Authors: Siu Kin Wai Michael
Published: October 2014

In recent years, postgraduate research students have been more expected to gain knowledge and experience through work-integrated learning. The key advantages of work-integrated learning include non-conventional university support and facility for research. Students can also gain alternative and other in-depth and comprehensive experience in the research area. This off-campus learning also provides opportunities for students to explore other research interests. On the other hand, work-integrated learning has its deficiencies and limitations. Since the learning is conducted outside the university, it is difficult to make arrangement and be available, in particular most of the time not the best available locally. Therefore, work-integrated learning is sometimes necessary to be carried out in remote regions. This situation creates more barriers and un-predictable matters for planning, implementation and management of the learning. To review the needs of work-integrated learning, this paper takes a collaboration of work-integrated learning for postgraduate design research students between the Chinese mainland and Hong Kong as a case study. The paper then identifies some key issues and problems. After that, the paper identifies and discusses possibilities for improvement and directions for further investigation.

Background: Proficiency testing (PT) is a means of verifying the reliability of laboratory results, but such programmes are not readily available to laboratories in developing countries. This project provided PT to laboratories in Nigeria.Objectives: To assess the proficiency of laboratories in the diagnosis of HIV, tuberculosis and malaria.Methods: This was a prospective study carried out between 2009 and 2011. A structured questionnaire was administered to 106 randomly-selected laboratories. Forty-four indicated their interest in participation and were enrolled. Four rounds of pre-characterised plasma panels for HIV, sputum films for tuberculosis and blood films for malaria were distributed quarterly by courier over the course of one year. The results were returned within two weeks and scores of ≥ 80% were reported as satisfactory. Mentoring was offered after the first and second PT rounds.Results: Average HIV PT scores increased from 74% to 95% from the first round to the third round, but decreased in the fourth round. For diagnosis of tuberculosis, average scores increased from 42% in the first round to 78% in the second round; but a decrease to 34% was observed in the fourth round. Malaria PT performance was 2% at first, but average scores increased between the second and fourth rounds, culminating in a fourth-round score of 39%. Many participants requested training and mentoring.Conclusions: There were gross deficiencies in the quality of laboratory services rendered across Nigeria. In-country PT programmes, implemented in conjunction with mentoring, will improve coverage and diagnosis of HIV, tuberculosis and malaria.
Chemical reaction on MHD flow and heat transfer of a nanofluid near the stagnation point over a permeable stretching surface with non-uniform heat source/sink
Authors: Gireesha B. J. , Rudraswamy N. G.
Published: October 2014

A numerical investigation has been conducted to study the laminar, boundary layer stagnation point flow of a nanofluid over a permeable, vertical stretching sheet. The model used incorporates the effects of Brownian motion with thermophoresis in the presence of uniform magnetic field and non-uniform source/sink under the influence of chemical reaction. Governing partial differential equations are transformed into a set of nonlinear ordinary differential equations using suitable similarity transformations. The transformed equations are then solved numerically using well known Runge-Kutta-Fehlberg method of fourth-fifth order with the help of symbolic software MAPLE. The influence of governing parameters on flow field, temperature and nanoparticle volume fraction profiles are provided both in graphical and tabular form. It is observed that heat source/sink with thermophoresis particle deposition in the presence of magnetic field have a substantial effect on the flow field and thus, on the heat and mass transfer rate from the sheet to the fluid. As the strength of the chemical reaction is higher than the thermophoresis particle deposition, nanoparticle volume fraction of the fluid gradually decreases. A comparative study has been conducted and is found to be in excellent agreement.Keywords: Stagnation point flow; Chemical reaction; Heat transfer; Stretching surface; Nanofluid; Numerical solution.
The role of the northward-directed (sub)surface limb of the Atlantic Meridional Overturning Circulation during the 8.2 ka event
Authors: Tegzes A. D. , Jansen E. , Telford R. J.
Published: October 2014

Abstract. The so-called "8.2 ka event" is widely regarded as a major Holocene climate perturbation. It is most readily identifiable in the oxygen-isotope records from Greenland ice cores as an approximately 160-year-long cold interval between 8250 and 8090 years BP. The prevailing view has been that the cooling over Greenland, and potentially over the northern North Atlantic at least, was triggered by the catastrophic final drainage of the Agassiz–Ojibway proglacial lake as part of the remnant Laurentide Ice Sheet collapsed over Hudson Bay at around 8420 ± 80 years BP. The consequent freshening of surface waters in the northern North Atlantic Ocean and the Nordic Seas resulted in weaker overturning, and hence reduced northward ocean heat transport. We have reconstructed variations in the strength of the eastern branch of the Atlantic Inflow into the Nordic Seas around the time of the lake outbursts. While the initial freshwater forcing may have been even larger than originally thought, as the lake outbursts may have been accompanied by a major iceberg discharge from Hudson Bay, our proxy records from the mid-Norwegian Margin do not evidence a uniquely large slowdown in the eastern branch of the Atlantic Inflow at the time. Therefore, its main role in the 8.2 ka event may have been the (rapid) advection of fresh and cold waters to high northern latitudes, initiating rapid sea-ice expansion and an increase in surface albedo.
Data assimilation of GRACE terrestrial water storage estimates into a regional hydrological model of the Rhine River basin

Published: October 2014

Abstract. The ability to estimate Terrestrial Water Storage (TWS) realistically is essential for understanding past hydrological events and predicting future changes in the hydrological cycle. Inadequacies in model physics, uncertainty in model land parameters, and uncertainties in meteorological data commonly limit the accuracy of hydrological models in simulating TWS. In an effort to improve model performance, this study investigated the benefits of assimilating TWS estimates derived from the Gravity Recovery And Climate Experiment (GRACE) data into the OpenStreams-wflow model using an Ensemble Kalman Filter (EnKF) approach. The study area chosen was the Rhine River basin, which has both well-calibrated model parameters and high-quality forcing data that were used for experimentation and comparison. Four different case studies were examined which were designed to evaluate different levels of forcing data quality and resolution including those typical of other less well-monitored river basins. The results were validated using in situ groundwater and stream gauge data. The analysis showed a noticeable improvement in groundwater estimates when GRACE data were assimilated, with an overall improvement of up to 71% in correlation coefficient (from 0.31 to 0.53) and 35% in RMS error (from 8.4 to 5.4 cm) compared to the reference (ensemble open-loop) case. Only a slight overall improvement was observed in streamflow estimates when GRACE data were assimilated. Further analysis suggested that this is likely due to sporadic short terms, but sizeable, errors in the forcing data and the lack of sufficient constraints on the soil moisture component. Overall, the results highlight the benefit of assimilating GRACE data into hydrological models, particularly in data-sparse regions, while also providing insight on future refinements of the methodology.
Examining Differences in Short-Haul and Long-Haul Markets in US Commercial Airline Passenger Demand
Authors: Elking Isaac , Windle Robert
Published: October 2014

This article examines the demand for US domestic airline passenger transportation as it pertains to short-haul markets of 500 miles or less, and compares it to the demand in long-haul markets of longer than 500 miles. We investigate how a variety of factors impact passenger volumes, depending on route distance, using a panel set of quarterly data from 1995 to 2010. We find that changes in security screening times, price differences between air travel and automobile travel, and market concentration levels affect short-haul and long-haul markets in statistically different ways, while the impact of low-cost carriers on passenger volumes affects both markets identically.
P3 Alliance and Its Implications on Contestability in Major Gateway Ports in North America
Authors: Yap Wei Yim
Published: October 2014

The P3 Alliance consists of the three biggest container shipping lines in the world. Together, Maersk Line, Mediterranean Shipping Company (MSC), and CMA CGM will command a combined market share of 36.4 percent of the world's active shipping capacity. Major gateway container ports in North America play a crucial role in serving the largest economy in the world and respective hinterlands that are embedded within. As such, the article aims to examine the impact of the P3 Alliance and its implications on contestability in the major gateway container ports in North America. Our analysis contends that the alliance should not be a cause of concern for the key ports of Los Angeles and Long Beach on the West Coast of the United States as the combined market share in terms of shipping capacity supplied matches up to existing capacity supplied by the largest of the other shipping alliances. However, the significantly higher market share for shipping capacity deployed by the alliance at major gateway container ports on the East Coast of the United States and stakeholding by Maersk Line's sister company APM Terminals and MSC's subsidiary Terminals Investment Limited in some of the ports could raise concerns for potential abuse of market power.
A Shift in Fundamentals:
Authors: Holcomb Mary C. , Liao-Troth Sara , Manrodt Karl B.
Published: October 2014

The Great Recession of the late 2000s created a turbulent business environment that is forcing managers to reevaluate how to manage their resources effectively and efficiently. In the logistics and transportation domain the primary forces of change include, but are not limited to: rapidly changing customer requirements, increasing energy (fuel) prices, the rising cost to serve, mounting inventory costs, and growing total landed costs. These forces of change have shifted the strategic direction of the firm toward a mixed approach where firms attempt to be “all things to all people,” thereby competing on both cost and service. In contrast, the study results indicate that during and after the recession the primary goal or objective of the firm was cost reduction. Customer service as a primary goal or objective has steadily declined, and has not yet returned to 2008 levels. This can be attributed to rising transportation, inventory, and distribution costs during a time of increasing customer service requirements. Two recommendations for managers are offered: to more fully understand the relationship between logistics costs and differentiated service; and to develop data and analytical capabilities that will enable them to deliver differentiated service of the right product for the right customer, in the right quantity and the right condition, at the right place, at the right time, at the right cost.

Towards Automated and Objective Assessment of Fabric Pilling
Authors: Furferi Rocco , Carfagni Monica , Governi Lapo , Volpe Yary , Bogani Patrizia
Published: October 2014

Pilling is a complex property of textile fabrics, representing, for the final user, a non-desired feature to be controlled and measured by companies working in the textile industry. Traditionally, pilling is assessed by visually comparing fabrics with reference to a set of standard images, thus often resulting in inconsistent quality control. A number of methods using machine vision have been proposed all over the world, with almost all sharing the idea that pilling can be assessed by determining the number of pills or the area occupied by the pills on the fabric surface. In the present work a different approach is proposed: instead of determining the number of pills, a machine vision-based procedure is devised with the aim of extracting a number of parameters characterizing the fabric. These are then used to train an artificial neural network to automatically grade the fabrics in terms of pilling. Tested against a set of differently pilled fabrics, the method shows its effectiveness.
Technical Feasibility Analysis for Introduction of Ethanol Fuel in the Energy Matrix of Portugal
Authors: Gelain Anna Júlia Lorenzzon , Emami Seyedali
Published: October 2014

Greenhouse gas emissions are among the major sources of global warming issue. Carbon dioxide emitted by burning of fossil fuels has a major contribution on this effect. Renewable energy resources such as biofuels have found to be a promising alternative, with positive impacts on environment, and a significant decrease of the critical issues related to the consumption of fossil fuels. Ethanol has been used as an alternative for fossil fuels in many regions such as Brazil and USA. Despite major advantages and facilities of Ethanol, this biofuel has not yet been considered in the Portuguese energy matrix. In this paper, we present the main aspects of the life cycle of this fuel, as well as a proof of its viability through a successful case study. A Life Cycle Impact Assessment (LCIA) of wheat-based ethanol was simulated with the Gabi® software, and then crossed all the information to find out what would be the best option to introduce this biofuel in the energy matrix of Portugal. Despite the limitations on the use of this fuel (agricultural and technological factors), knowing that there are no flex vehicles in the country, recent advances in this field of research could work as a great incentive to show that it is increasingly possible to use this biofuel.

Researches about volatility transmission between small and large company stocks had received great attention in last years. Based on this idea, the current paper aims to analyze the occurrence of volatility transmission  between small and large companies in Brazil. To that, we estimate multivariate GARCH models. As asset proxies we used the Small and Mid-Large cap BMF/Bovespa index. Results allow concluding that large company stocks impact the small stocks conditional volatility. However, the relationship does not maintain it in reverse direction. This result is in accord with the addressed subject.

The Role of Gender Dynamics in the Relationship between Parental Maltreatment and Juvenile Theft in South Korea
Authors: Hong Hyunhee , Han Yoonsun , Lee Dong Hun
Published: October 2014

Juvenile theft is the leading crime among adolescents in Korea and is a serious social concern. The present study is an examination of youth theft in the framework of general strain theory, which asserts that criminal behavior occurs as a response to various strains, such as parental abuse and neglect. To test the role of parent-youth gender dynamics in the relationship between parental strain and youth theft, the current study analyzed a community-based sample of youth offenders and non-offenders in Korea (N = 374) using multivariate logistic regression models with interaction terms. Paternal physical abuse and maternal neglect predicted greater youth involvement in theft behavior. Regarding parent-youth gender dynamics, there was no difference in the role of maternal or paternal maltreatment in predicting theft behavior in sons or daughters. The exception was fathers’ neglect, in which daughters showed higher odds of theft engagement than did sons who experienced even greater paternal neglect. The findings underscored the distinct and detrimental role of parental maltreatment in adolescent theft. The results supported the need to reach out to parents in consideration of the youth’s gender and provided important implications for guiding current social services in preventing juvenile theft in Korea.
(Il)légitimité du renseignement financier
Authors: Amicelle1 Anthony
Published: October 2014

Cet article est consacré à un enjeu encore trop peu étudié malgré son importance croissante dans un domaine tel que le policing transnational, à savoir le renseignement financier. Afin de contribuer à la réflexion sur cette composante à part entière des pratiques contemporaines de surveillance ou plutôt de dataveillance, l’analyse porte plus précisément sur le programme américain de traque du financement du terrorisme (Terrorist Finance Tracking Program [TFTP]). Fondé sur un espace de relations à la fois au-dessus, au-delà et en deçà du national, ce programme de sécurité participe à la production de renseignement à partir d’un dispositif de traçabilité des flux financiers. Il s’agit ici d’expliciter les conditions d’existence d’un tel dispositif consistant à mobiliser de larges ensembles de traces numériques générés par une forme particulière de circulation transfrontière. Il s’agit aussi de mettre la légitimité du TFTP à l’épreuve des narratifs de justification et des « réussites » qui lui sont associés.
Technologies, déqualification et luttes d’influence chez les professionnels de la sécurité frontalière
Authors: Côté-Boucher1 Karine
Published: October 2014

Les travaux sur la sécurité frontalière ont clairement établi que les technologies se situent au coeur de la reconstitution des activités de police frontalière et de l’espace occupé par les frontières. Cet article a pour but d’ouvrir ces perspectives vers le monde peu étudié des douanes, c’est-à-dire là où l’on se préoccupe de la traçabilité des marchandises et des déplacements des travailleurs du transport. En nous appuyant sur une recherche de terrain menée dans les divisions « commerciales » de cinq postes frontaliers canadiens, nous posons la question des effets concrets de l’intégration des technologies dans les procès de travail douaniers. Nous nous penchons sur la manière dont les douaniers se constituent comme acteurs de sécurité, mais également sur les pratiques quotidiennes des professionnels de la sécurité frontalière, les conditions de travail et les relations intraorganisationnelles au sein de ces agences de sécurité frontalières. En effet, plutôt qu’une efficience accrue qui serait obtenue par le recours aux technologies, cette intégration présente des écueils qui révèlent, en creux, des luttes d’influence entre acteurs de terrain et cadres intermédiaires avec, en trame de fond, la déqualification et l’automatisation du travail douanier.

Los biosurfactantes (BS) son un grupo de moléculas de origen microbiano que se caracterizan por ser anfipáticas, es decir que sus moléculas presentan dos partes diferentes, una hidrofóbica y otra hidrofílica. Son un grupo estructuralmente diverso de moléculas tensoactivas, que presentan en general menor toxicidad y mayor biodegradabilidad que los surfactantes sintéticos. Entre las aplicaciones más estudiadas de los BS están aquellas relacionadas con la industria del petróleo y la bioremediación de sitios o residuos contaminados con hidrocarburos. No obstante, los biosurfactantes pueden ser utilizados para otro tipo de compuestos xenobióticos, como es el caso de los plaguicidas. Estos compuestos permiten controlar la proliferación de plagas y enfermedades de los cultivos y del ganado, así como reducir o evitar las pérdidas en la producción de alimentos y contribuir al control de los vectores de diversas enfermedades. No obstante la importancia económica de los plaguicidas, es necesario destacar que su aplicación indiscriminada y sin control ha generado diversos problemas como intoxicación a seres humanos, efectos carcinogénicos, teratogénicos y mutagénicos, además de numerosos problemas ambientales como contaminación de mantos freáticos, aguas continentales y costeras; contaminación del suelo y bioacumulación en las cadenas alimentarias. Generalmente los plaguicidas son de naturaleza hidrofóbica, por lo que el uso de los BS puede ser prometedor en la remediación de sitios contaminados o en el tratamiento biotecnológico de residuos de plaguicidas.
Lubrication Systems
Authors: Jenckes Charles H.
Published: October 2014

Lubrication is needed to prevent wear or failure of parts in relative motion and in close proximity. A lubricant is placed between the two surfaces to distribute the load and act as a coolant. The lubricant must support the applied load, keep the moving surfaces separated, reduce friction, control the temperature, and carry away debris. Fundamentally, the lubrication system must supply each contact interface within the engine with sufficient lubrication appropriate to each operating condition. The lubricant must be stored, filtered, and supplied to the needed locations to complete its lubrication mission; then cooled, and returned to the filter to close the loop.

Lubrication systems range from the simple splash lubrication system to the highly complex dry sump systems used in F1. This chapter covers the basics of automotive lubrication systems.
Application of Radio Wave Technologies to Vehicles
Authors: Naito Hiromichi
Published: October 2014

In the 1930s, the car radio heralded the introduction of vehicle components that use radio waves. Since then, various radio‐wave‐based automotive applications have been developed in accordance with the evolution of semiconductor technology and the spread of automotive electronics. These trends have helped elevate radio waves into a medium capable of data communication within vehicles and linking cars with people and society. This chapter outlines radio wave technologies and describes various automotive components that use radio waves.
Ergonomics for Passenger Cars
Authors: Marek Clemens , Siebertz Karl
Published: October 2014

Driving a vehicle is a demanding task, even if it is not done as a profession. Ergonomics therefore plays an important role during the development process. Human limits are manifold, which makes ergonomics a multidisciplinary task. Capacity and demand need to be considered simultaneously. This chapter explains various categories of human performance limits and brings this into an automotive context. International standards are introduced, along with an explanation of the tools and methods to apply the standards. Knowledge about the human body is an essential component of ergonomics. Key findings and methods in the areas of anthropometry, biomechanics, and physiology are described briefly. A practical guide through the layout of the driver's environment shows how the specific knowledge can be applied in order to optimize the ergonomics of passenger vehicles. A few considerations related to vehicle evaluation conclude the chapter. Owing to the complexity of the subject, this chapter can only provide an overview and refers to literature sources for further reading.
Visual Imaging for Diagnosis and Robotic Surgery
Authors: Kumar Rajesh
Published: October 2014

Visual imaging has remained the primary modality for manual clinical assessment and intervention in abdominal surgery despite the increasing popularity of radiological imaging‐based diagnosis. This includes endoscopic diagnosis laboratories and laparoscopic and robotic laparoscopic telesurgical procedures. Advances such as wireless capsule endoscopes and robotic surgeries have both provided visual access to organs previously not well imaged and improved the quality and adoption of minimally invasive techniques. This chapter summarizes the technology and applications of visual diagnosis and visually guided robotic surgery along with image analysis methods in development for these images.
Fundamentals of Optics and Radiometry for Color Reproduction
Authors: Hébert Mathieu , Hersch Roger D. , Emmel Patrick
Published: October 2014

Visual appearance of objects comes from the interpretation by the human visual system of a light signal issued from the objects. Describing or predicting appearance is, therefore, a question of light and requires notions about light propagation and measurement. In this chapter, we introduce basic laws of optics, the science of light, and radiometry, the science of light measurement, in the context of colored surfaces. We address light spectrum and illuminants, polarization, notions of reflectance and transmittance based on radiometric definitions, gloss, absorption, scattering, fluorescence, and models for light reflection and transmission by flat and rough surfaces and by slabs of nonscattering media and diffusing layers. Throughout the chapter, we present the most current methods to assess the different physical quantities by measurement.

Morquio A syndrome (mucopolysaccharidosis IVA) is a lysosomal storage disorder associated with skeletal and joint abnormalities and significant non‐skeletal manifestations including respiratory disease, spinal cord compression, cardiac disease, impaired vision, hearing loss, and dental problems. The clinical presentation, onset, severity and progression rate of clinical manifestations of Morquio A syndrome vary widely between patients. Because of the heterogeneous and progressive nature of the disease, the management of patients with Morquio A syndrome is challenging and requires a multidisciplinary approach, involving an array of specialists. The current paper presents international guidelines for the evaluation, treatment and symptom‐based management of Morquio A syndrome. These guidelines were developed during two expert meetings by an international panel of specialists in pediatrics, genetics, orthopedics, pulmonology, cardiology, and anesthesia with extensive experience in managing Morquio A syndrome. © 2014 The Authors.

Mithilfe eines Pikosekunden‐IR‐Lasers (PIRL) können Proteine in weniger als einer Millisekunde aus intakten Geweben in die Gasphase katapultiert werden. Die ultraschnelle Desorption erfolgt durch eine impulsive Anregung intramolekularer Vibrationszustände (DIVE) der Wassermoleküle, die die Proteine innerhalb des Gewebes umgeben. PIRL‐DIVE extrahiert mit hohen Ausbeuten eine große Vielzahl unterschiedlicher Proteine, von wenigen kDa bis zu mehreren MDa. Die chemische Zusammensetzung der Proteine wird durch die Energie des PIRL nicht verändert. Der Nachweis von Enzymaktivitäten in den PIRL‐Extrakten weist darauf hin, dass die Konformation der Enzyme erhalten bleibt.
