Does Implementation of Biomathematical Models Mitigate Fatigue and Fatigue related Risks in Emergency Medical Services Operations? A Systematic Review
Venue: Prehospital emergency care official journal of the National Association of EMS Physicians and the National Association of State EMS Directors
Year: 2018

Work schedules like those of Emergency Medical Services (EMS) personnel have been associated with increased risk of fatigue related impairment. Biomathematical modeling is a means of objectively estimating the potential impacts of fatigue on performance, which may be used in the mitigation of fatigue related safety risks. In the context of EMS operations, our objective was to assess the evidence in the literature regarding the effectiveness of using biomathematical models to help mitigate fatigue and fatigue related risks.  A systematic review of the evidence evaluating the use of biomathematical models to manage fatigue in EMS personnel or similar shift workers was performed. Procedures proposed by the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) methodology were used to summarize and rate the certainty in the evidence. Potential bias attached to retained studies was documented using the Cochrane Collaboration's Risk of Bias tool for experimental studies.  The literature search strategy, which focused on both EMS personnel and non EMS shift workers, yielded n 2,777 unique records. One paper, which investigated non EMS shift workers, met inclusion criteria. As part of a larger effort, managers and dispatchers of a trucking operation were provided with monthly biomathematical model analyses of predicted fatigue in the driver workforce, and educated on how they could reduce predicted fatigue by means of schedule adjustments. The intervention showed a significant reduction in the number and cost of vehicular accidents during the period in which biomathematical modeling was used. The overall GRADE assessment of evidence quality was very low due to risk of bias, indirectness, imprecision, and publication bias.  This systematic review identified no studies that investigated the impact of biomathematical models in EMS operations. Findings from one study of non EMS shift workers were favorable toward use of biomathematical models as a fatigue mitigation scheduling aid, albeit with very low quality of evidence pertaining to EMS operations. We propose three focus areas of research priorities that, if addressed, could help better elucidate the utility and impact of biomathematical models as a fatigue mitigation tool in the EMS environment.
Take Off! Aeronautics and Aviation Science: Careers and Opportunities
Year: 2013

Funded by National Aeronautic and Space Administration's High Performance Computing and Communications/ Learning Technologies Project (HPCC/LTP) Cooperative Agreement, Aeronautics and aviation  Careers and Opportunities was operative from July 1995 through July 1998. This project operated as a collaboration with Massachusetts Corporation for Educational Telecommunications, the Federal Aviation Administration, Bridgewater State College and four targeted "core sites" in the greater Boston area: Dorchester, Malden, East Boston and Randolph. In its first and second years, a video series with a participatory website on aeronautics and aviation science was developed and broadcast via "live, interactive" satellite feed. Accompanying teacher and student supplementary instructional materials for grades 6 12 were produced and disseminated by the Massachusetts Corporation for Educational Telecommunications (MCET) In year three, the project team redesigned the website, edited 14 videos to a five part thematic unit, and developed a teacher's guide to the video and web materials supplement for MAC and PC platforms, aligned with national standards. In the MCET grant application it states that project Take Off! in its initial phase would recruit and train teachers at "core" sites in the greater Boston area, as well as opening participation to other on line users of MCET's satellite feeds. "Core site" classrooms would become equipped so that teachers and students might become engaged in an interactive format which aimed at not only involving the students during the "live" broadcast of the instructional video series, but which would encourage participation in electronic information gathering and sharing among participants. As a Take Off! project goal, four schools with a higher than average proportion of minority and underrepresented youth were invited to become involved with the project to give these students the opportunity to consider career exploration and development in the field of science aviation and aeronautics. The four sites chosen to participate in this project were East Boston High School, Dorchester High School, Randolph Junior Senior High School and Malden High School. In year 3 Dorchester was unable to continue to fully participate and exited out. Danvers was added to the "core site" list in year 3.
Construction and expression of humanized anti EGFR antibody
Year: 2009

To express rationally engineered antibodies against EGFR and assess their affinity to EGFR and anti tumor cell migration effect.L and VH genes of humanized antibodies against EGFR were designed and synthesized.Genes encoding VH and CH were connected and then cloned into a pIRES based bicistronic expression vector.Gene encoding the corresponding L gene was also cloned into the same vector.293T cells were transfected with the recombinant plasmid and the antibody expression was confirmed by Western blotting.The antibodies were purified by protein A based affinity chromatography.Binding of the humanized antibody to the EGFR was assessed by Surface Plasmon Renainance with Biacore3000,and the biological activity of the humanized antibody was determined by tumor cell invasion test.Three expression vectors were constructed and the humanized anti EGFR antibodies were expressed and purified successfully.In reducing SDS PAGE,the antibodies exhibited two bands of approximately 25x103and 50x103,respectively.Western blot assay showed that the humanized antibodies had recognition specificity to goat human IgG antiserum.Biacore assay revealed that the humanized antibody C3 binds to EGFR with high affinity(6.13x10 10M).Cell migration test showed that C2,C3 and C5 could suppress growth and migration of tumor cells.Three anti EGFR humanized antibodies (C2,C3 and C5) have been constructed and expressed successfully,and the C3 antibody retained high affinity for EGFR and showed improved inhibitory effect on tumor cell growth and migration.
A New Digital Map of Limits of Oceans and Seas Consistent with High Resolution Global Shorelines
Year: 2012

Fourcy, D. and Lorvelec, O. 2013. A new digital map of limits of oceans and seas consistent with high resolution global shorelines. We present a vector map of the limits of oceans and seas intended to be integrated into a geographic information system (GIS) This map is based on the document S 23 titled "Limits of Oceans and Seas" and published by the International Hydrographic Organization (IHO) The third edition of this document, published in 1953, still serves as an official reference. The realization of this map from a text containing numerous ambiguities, disused place names, or imprecise coordinates required important documentary investigations. This was made possible through the use of online resources such as map libraries, satellite imageries, geographic names databases, and institutional geoportals. The main innovations of our map are its accuracy, its precision of about 10 s of meridian arc, and its consistency with the Global, Self consistent, Hierarchical, High resolution Shoreline database and with satellite images such as Land Satellite and moderate resolution imaging spectroradiometer. All remaining uncertainties for the drawing of limits are presented in the results. Although based on an IHO document, our map does not possess any official status. Nevertheless, we hope that our map will facilitate and encourage more detailed spatial analyses related to oceans and seas. This map is freely available for noncommercial use.
Price rigidity in Europe and the US: A comparative analysis using scanner data
Year: 2010

This paper uses scanner data from two large retailers to offer new insights into the extent of price rigidity in Europe and the US. Recent empirical research in this field has made extensive use of monthly data to study price stickiness and to control for the impact of temporary sales. We show that the use of monthly data is potentially highly misleading. We employ scanner data in (bi)weekly frequency and highlight the importance of high frequency data in studying price rigidity. Regular prices show roughly the same degree of flexibility in Europe and the US, in line with recent empirical research, when we study monthly price series derived from our high frequency scanner data. This finding collapses, however, when the original scanner datasets in higher base frequency are examined. Regular prices are then far more flexible in the US than in Europe. This result is robust to the type of sales filter that we apply and the statistic used to capture price rigidity.
Effect of mineral fertilizers on agronomic characters of cacao trees species in the Daloa region (West Center, Cote d'Ivoire)
Year: 2016

Cote d'Ivoire became the first world producer of cocoa beans in 1970 by reducing forest cover and by losing biodiversity. The West central region of the country was a former production site of cocoa, and contributed strongly to the annual supply of cocoa beans, but today, the plantations are old and the soils are poor, especially in the region of Daloa. To increase the yield of production, farmers use artificial fertilizers and the effect on cocoa trees is not really known. Our study aims to determine the agronomic characters improved by the application of the artificial fertilizer. In the plantations of the villages Dibobly, tien oula and Zitta, non experimental and experimental plots were installed and measures on cacao trees on a surface of 2 400m2 were realized. The results showed that the cover of flowers by feet and the number of fruits had significantly increased with fertilizer. However, the fertilizer had no really effect on the size of fruits, the mass of fruits and the number of cocoa beans. Also, the varieties of cocoa trees like Forastero and Criollo, had a different productivity for the same application of fertilizer. The productivity of the cocoa trees depends of the quality of the fertilizer but also of the cultivated variety. The results could allow improving the quality of the fertilizer and use it consequently.
Hybrid Vehicle Optimal Control: Linear Interpolation and Singular Control
Venue: 2014 IEEE Vehicle Power and Propulsion Conference (VPPC)
Year: 2014

Hybrid vehicle energy management can be formulated as an optimal control problem. Considering that the fuel consumption is often computed using linear interpolation over lookup table data, a rigorous analysis of the necessary conditions provided by the Pontryagin Minimum Principle is conducted. For most the co state values, the control value is well defined and can be computed without any interpolation but this only generate a finite set of state trajectory. To compute the remaining trajectories, it is necessary to consider specific co state values that generate singular controls. An algorithm is provided for the optimization of both the APU power and binary state and an infinite number of optimal solutions can be constructed.
When Staying Is Dissatisfying: Examining When and Why Turnover Cognitions Affect Stayers' Career Satisfaction
Year: 2020

This study examines when and why turnover cognitions affect stayers' subsequent career satisfaction. To develop our hypotheses, we build on and compare two theoretical perspectives, that is, the insufficient justification perspective and regret theory. Hypotheses were tested using two studies with Belgian employees. The baseline hypothesis that initial turnover cognitions are related with lower subsequent career satisfaction received support in both studies. In Study 1, using two wave data from 226 employees in four organizations, we tested whether the turnover cognitions subsequent career satisfaction relationship was moderated by four contextual factors (i.e. internal job transitions, lack of external job opportunities, on the job embeddedness, and off the job embeddedness) We found marginal support for a mitigating role of internal job transitions, support for a mitigating role of lack of external job opportunities, and support for an amplifying role of off the job embeddedness. We found no moderation effect of on the job embeddedness. In Study 2, using three wave information from 705 employees in seven organizations, we tested and found support for the mediating role of justifiability and regret. Overall, this study shows that turnover cognitions have consequences when people end up staying in their organization, which calls for more theoretical and empirical work on staying despite preceding turnover cognitions in order to improve our understanding of the complexity and dynamic nature of the turnover/retention phenomenon.
Localized surface plasmon resonance coupling in Au nanoparticles/phosphorus dendrimer multilayer thin films fabricated by layer by layer self assembly method
Year: 2009

Multilayer thin films of anionic gold nanoparticles (AuNPs) and cationic phosphorus dendrimers were deposited on 3 (diethoxymethyl silyl)propylamine (3 APDMES) coated substrates using layer by layer (LbL) assembly driven by electrostatic interactions. The growth of Au/dendrimer multilayers composed of AuNPs with diameters of ~3 nm and ~16 nm and dendrimer with ~2 nm diameter was monitored by UV vis spectroscopy. The relative amounts of AuNPs and dendrimers in the multilayer films were calculated using a quartz crystal microbalance. The Au containing multilayers have two surface plasmon bands at ~530 nm and ~600 nm, where the latter exhibits a red shift upon increasing the areal density of AuNPs as well as increasing the layer number. The localized surface plasmon resonance (LSPR) band of the hybrid films can be tuned by adding NaCl to the dendrimer solution or by removing the organic matrix. These results demonstrate that the near field coupling between the LSPR bands of neighboring Au layers is responsible for the controlled absorption behavior. Au mesoporous films after removing dendrimers show LSPR sensing properties for alcohols with different refractive indices in the range 1.33 1.41. A linear relationship was obtained between the LSPR peak wavelength and the refractive index of the surrounding medium.
Experimental Analogue Implementation of Memristor Based Chaotic Oscillators
Year: 2017

The theory of memristor was postulated in the year of 1971 by Leon O. Chua. The intensive interest on memristive systems is given by the researchers since after the physical realization of the hysteresis behavior in a nanoscale TiO\(_{\mathrm {2} memristor in 2008 by a group of researchers at HP Labs lead by Stanley Williams. Research on memristive systems has been carried out on various capacities such as understanding the mathematics of memristor, finding new materials which have memristive properties, studying the underlying dynamics of memristive systems and revisiting the existing concepts with memristor as a nonlinear element. As a result, memristors have potential applications in various domains. It ranges from neural networks, memory devices, artificial intelligence, high speed computing, nano batteries and human skin modeling, etc. In the recent times, much attention is given to explore the nonlinear dynamics of memristor based circuits. In this chapter, we consider a smooth continuous cubic memristor as nonlinear element. It is applied to (a) an autonomous and (b) a non autonomous dynamical systems namely, the Chua's circuit and Duffing Oscillator, to study the associated dynamics of these systems. The numerical simulation of the circuit systems as well as its hardware experimental studies are performed in the laboratory. An inductor free realization and volume expanded period doubling scenario in a memristive Chua's circuit is studied. The complex behaviors, like, bifurcations and chaos, three tori, transient chaos and intermittency in a memristive Duffing oscillator are described. In addition, "0 1 test" for the experimental time series data characterizing the regular and chaotic dynamics of the proposed circuits are also discussed.
What Image Does IR Project? Chess, a Visual Metaphor for IR
Year: 2017

The article focuses on the image the discipline of International Relations (IR) projects of itself via visuals, particularly the image of chess on IR book covers. It points out the corroborative and critical role that images can play in defining the way we see IR. The article underlines particular features of visual metaphors, first pointing out their role in the epistemological process, and second, highlighting their capacity for voicing an expressive and captivating critique of the social world, which is enabled by the template they offer, a template that may be distorted and manipulated for expressing criticism. Finally, the article reflects on the image chess conveys about expectations of the kind of knowledge IR as a discipline could provide for "mastering" the world and identifying a winning strategy. Here, the image of chess is compared to insights offered by Clausewitz's pendulum.
Flow and heat transfer analysis of hybrid cooling schemes: Adding micro jets to a micro gap
Venue: International Journal of Thermal Sciences
Year: 2019

An extensive, combined experimental and numerical analysis is presented as a method for physically driven, systematic improvement of heat transfer, applied to a single phase hybrid quasi 2D cooling scheme, merging impinging flow with that parallel to a heated plate. Thereby cooling fluid is introduced into a micro gap in a gradual way, through a succession of impinging micro slot jets. Both the distributed inflow and impinging flows improve heat transfer and especially wall temperature uniformity. For a specific micro fabricated system, the influence of flow rate is examined in an experimental study employing wall side infrared thermography and flow visualization by micro PIV. The measurements reveal the location of standing vortices and jet's deflection of the main flow towards the wall, and the characteristics of these flow patterns, associated with around 20% heat transfer enhancement. These flow patterns and wall heat transfer are quantitatively reproduced by numerical simulation spanning the transitional flow regime. From insights gained, the base configuration is varied numerically in terms of jet array location and pitch, micro jet slot hydraulic diameter and initial flow distribution. As a result, a much improved configuration is identified, yielding a total heat transfer enhancement of almost 60% as compared to a plain gap at the same overall flow rate, while attaining even more significant improvement in wall temperature uniformity. The systematic method followed to obtain such improvement is described in detail to facilitate future studies.
Sustainable quality management: a strategic perspective
Year: 2006

The topic is restricted to the components of total quality management (TQM) in which a set of values, tools and techniques unites the descriptions of TQM. The purpose of this paper is to discuss the impact on an additional core value of the components of TQM, namely the sustainability of values, tools and techniques.  A strategic perspective of sustainable quality management is applied, rather than tactical and operative ones. The term "sustainable quality management" is used.  The paper contends that quality management (in general) and TQM (in particular) should be scrutinised by stressing the sustainability of values, tools and techniques.  Sustainable quality management provides a potential to improve and extend the theory generation and the best practices of TQM in the future. An important area for further research is to examine the extent of sustainable quality management practices beyond the organisational boundaries and traditional channel structures. Sustainable quality management is complex to implement and evaluate.  The paper provides theoretical and managerial ideas and insights in order to anticipate and avoid the non sustainability of TQM practices.  One contribution is a model of a circulation approach to TQM. Another contribution is a model of the sustainability of TQM, which connects and reconnects corporate values, tools and techniques in quality management.
