Thriving at work: A meta analysis
Venue: Journal of Organizational Behavior
Year: 2019

Thriving at work refers to a positive psychological state characterized by a joint senseof vitality and learning. On the basis of Spreitzer and colleagues' model, we present acomprehensive meta analysis of antecedents and outcomes of thriving at work(K= 73 independent samples,N= 21,739 employees) Results showed that thrivingat work is associated with individual characteristics, such as psychological capital(rc= .47) proactive personality (rc= .58) positive affect (rc= .52) and work engage ment (rc= .64) Positive associations were also found between thriving at work andrelational characteristics, including supportive coworker behavior (rc= .42) support ive leadership behavior (rc= .44) and perceived organizational support (rc= .63).Moreover, thriving at work is related to important employee outcomes, includinghealth related outcomes such as burnout (rc= .53) attitudinal outcomes such ascommitment (rc= .65) and performance related outcomes such as task performance(rc= .35) The results of relative weights analyses suggest that thriving exhibits small,albeit incremental predictive validity above and beyond positive affect and workengagement, for task performance, job satisfaction, subjective health, and burnout.Overall, the findings of this meta analysis support Spreitzer and colleagues' modeland underscore the importance of thriving in the work contex
The origin of high electrolyte electrode interfacial resistances in lithium cells containing garnet type solid electrolytes.
Venue: Physical chemistry chemical physics PCCP
Year: 2014

Dense LLZO (Al substituted Li7La3Zr2O12) pellets were processed in controlled atmospheres to investigate the relationships between the surface chemistry and interfacial behavior in lithium cells. Laser induced breakdown spectroscopy (LIBS) scanning electron microscopy (SEM) X ray diffraction (XRD) Raman spectroscopy, synchrotron X ray photoelectron spectroscopy (XPS) and soft X ray absorption spectroscopy (XAS) studies revealed that Li2CO3 was formed on the surface when LLZO pellets were exposed to air. The distribution and thickness of the Li2CO3 layer were estimated by a combination of bulk and surface sensitive techniques with various probing depths. First principles thermodynamic calculations confirmed that LLZO has an energetic preference to form Li2CO3 in air. Exposure to air and the subsequent formation of Li2CO3 at the LLZO surface is the source of the high interfacial impedances observed in cells with lithium electrodes. Surface polishing can effectively remove Li2CO3 and dramatically improve the interfacial properties. Polished samples in lithium cells had an area specific resistance (ASR) of only 109 O cm(2) for the LLZO/Li interface, the lowest reported value for Al substituted LLZO. Galvanostatic cycling results obtained from lithium symmetrical cells also suggest that the quality of the LLZO/lithium interface has a significant impact on the device lifetime.
STUDY OF THE NANOPARTICLE POLYMER CACO3 INTERACTIONS TO OPTIMIZE THE STABILITY OF THE COLLOIDAL SUSPENSION AND THE PACKING OF THE SOLIDS
Year: 2019

Nowadays, interest in nanotechnology in drilling and completion operations has increased to reduce the formation damage and improve the properties of the drilling fluids. In this way, this study aims to evaluate the effect of the SiO2 nanoparticles in a drill in fluid (polymer and calcium carbonate) to minimize its impact in the formation damage based on the filtration and thickness mudcake reduction through the interaction polymer/nanoparticle/calcium carbonate. Rheological behavior of the polymeric solution and the drilling fluid in absence and presence of nanoparticles were evaluated. Additionally, the static and dynamic filtration test was carried out under reservoir conditions. SiO2 nanoparticles exhibited an increase in the viscosity of the polymeric solution and drilling fluid due to and polymer adsorption onto nanoparticles surface. Drilling fluid with the addition of SiA nanoparticles reduced and stopped the filtration volume by 77% decreasing the formation damage by 51% and hence increased the permeability returns by 74% compared to the drilling fluid without nanoparticles.
Farming Approaches for Greater Biodiversity, Livelihoods, and Food Security.
Venue: Trends in ecology evolution
Year: 2017

Scientists and policy makers globally are calling for alternative approaches to conventional intensification of agriculture that enhance ecosystem services provided by biodiversity. The evidence reviewed here suggests that alternative approaches can achieve high crop yields and profits, but the performance of other socioeconomic indicators (as well as long term trends) is surprisingly poorly documented. Consequently, the implementation of conventional intensification and the discussion of alternative approaches are not based on quantitative evidence of their simultaneous ecological and socioeconomic impacts across the globe. To close this knowledge gap, we propose a participatory assessment framework. Given the impacts of conventional intensification on biodiversity loss and greenhouse gas emissions, such evidence is urgently needed to direct science policy initiatives, such as the United Nations (UN) 2030 Agenda for Sustainable Development.
SAT0370 Evaluations of exertion dyspnea in patients with connective tissue disease (CTD) by CPET (cardiopulmonary exercise testing) for early detecting associated pulmonary hypertension (APAH)
Year: 2017

Patients with CTD often complain of exertion dyspnea, due to lung diseases, heart diseases, musculoskeletal disorders and/or APAH. Although imaging and physiological tests could reveal pathophysiology, some of them remain unknown. Especially APAH is rarely diagnosed in WHO functional class I or II, because pulmonary vasculopathy (PV) cannot be detected until two thirds of pulmonary blood vessels deteriorated, 1 with cardiac ultrasonography (UCG) or right heart catheterization (RHC) at rest. Pathophysiological considerations suggest that the haemodynamic/metabolic impairment in APAH may be observed during exercise before the disease becomes evident at rest.2 3 We evaluated exertion dyspnea of unknown to find out early APAH with CPET.  We performed CPET in patients who complained of exertion dyspnea and tried to detect early PV.  From June 13th in 2015 to October 28th in 2016, we performed CPET and evaluate their clinical state in 28 patients, 17 80 years 2 males/26 females, 5 mixed connective tissue disease (MCTD) 15 SSc, 3 SLE, 2 Sjogren's syndrome, 3 dermatomyositis. They underwent UCG, pulmonary function testing (PFT) 6 minutes walk test, and nailfold capillaroscopy by Cutolo's method.4  Twenty cases presented decreased peak VO2. VE/VCO2 ratio, which represent increased ventilation perfusion mismatch, elevated in 12 cases. 8 cases, with decreased peak VO2 but normal VE/VCO2, were regarded that muscle weakness mainly induced exertion dyspnea, and advised exercise. Twelve cases with decreased peak VO2 and elevated VE/VCO2 were estimated to have APAH or/and interstitial lung disease (ILD) Seven of them underwent RHC and 1 case diagnosed as definite APAH, and another 1 case as post capillary PH. A 34 years MCTD woman without ILD showed an active capillaroscopic pattern, her peak VO2 decreased (13.9ml/kg/min. and nadir VE/VCO2 elevated (39) Although her mean PAP was normal, we suspected she had early PV and administered PDE5 inhibitor to her and her dyspnea had gone soon and CPET parameters improved. CPET was also useful for early detections of therapeutic gains in APAH. A SSc woman, diagnosed as APAH by RHC, was performed CPET only 9 days after administration of PDE5 inhibitor. Her peak VO2 elavated (13.3 to 15.4 ml/kg/min. and nadir VE/VCO2 decreased (43.4 to 38.9) promptly. Thirteen patients showed an early capillaroscopic pattern, 7 an active pattern and 3 a late pattern. Median values of minimum VE/VCO2 ratio significantly differed (p<0.05) in the three capillaroscopic groups, being progressively worse from early to late capillaroscopic pattern.  We performed CPET in every patient safely. Although more research is required, CPET may provide valuable information notably in APAH patients.
Incorporating sharp crested weirs into irrigation SCADA systems
Year: 2020

Real time flow measurement and monitoring are important components of modern irrigation SCADA systems. Many projects have existing sharp crested weir structures that have not been incorporated into SCADA systems because they are partially contracted, and thus do not have a simple rating equation relationship. The Kindsvater Carter procedure for calibrating partially contracted sharp crested weirs is accurate and straightforward, but also somewhat tedious. Existing computer programs simplify the process but can presently be applied only to individual measurements. This paper presents a Microsoft(r) Excel spreadsheet model that can compute complete rating tables for sharp crested weirs with full or partial flow contraction, using the Kindsvater Carter procedure. Furthermore, through regression analysis, the spreadsheet determines a simplified rating equation that can easily be incorporated into remote terminal units (RTUs) and SCADA systems. The spreadsheet can be applied to fully contracted V notch weirs with included angles of 25deg to 100deg, partially or fully contracted 90deg V notch weirs, partially or fully contracted rectangular weirs (including suppressed rectangular weirs) and fully contracted Cipoletti weirs.
Local Thoughts on Global Ideas: Pre and In service TESOL Practitioners' Attitudes to the Pedagogical Implications of the Globalization of English
Venue: RELC Journal
Year: 2019

With the globalization of the English language, Global Englishes (GE) is a growing research paradigm with numerous pedagogical implications for those learning and teaching English. The study reported here provides insights on pre and in service Teaching English to Speakers of Other Languages (TESOL) practitioners' perceptions of Global Englishes Language Teaching (GELT) (Galloway Rose, 2015; Rose Galloway, 2019) which aims to make TESOL classrooms more reflective of learners' needs in today's globalized world, where multilingualism is the norm and English functions as a lingua franca. Interviews (n=5) with those taking a GE course on an MSc TESOL programme at a Russell Group university in the UK were triangulated with a survey among the wider programme (n=66) The study reveals that curriculum innovation is complex, particularly when it requires a conceptual transition, and practitioners need time and support to implement change. Furthermore, it was clarified that GE has made little headway into 'traditional' TESOL classrooms, which remains biased towards 'native' English norms.
IC laser trimming speed up through wafer level spatial correlation modeling
Venue: 2014 International Test Conference
Year: 2014

Laser trimming is used extensively to ensure accurate values of on chip precision resistors in the presence of process variations. Such laser resistor trimming is slow and expensive, typically performed in a closed loop, where the laser is iteratively fired and some circuit parameter (i.e. current) is monitored until a target condition is satisfied. Toward reducing this cost, we introduce a novel methodology for predicting the laser trim length, thereby eliminating the closed loop control and speeding up the process. Predictions are obtained from waferlevel spatial correlation models, learned from a sparse sample of die on which traditional trimming is performed. Effectiveness is demonstrated on an actual wafer of laser trimmed ICs.

A weiner filter based robust algorithm for estimation of heart rate from wrist based photoplethysmogram
Venue: UbiComp/ISWC Adjunct
Year: 2019

The paradigm of wellness consists of both physical and mental wellness. One important parameter of physical wellness in the monitoring of cardiac health during activity, which requires measurement of ambulatory heart rate (HR) With the advent of smart wearable devices, measurement of heart rate using Photoplethysmogram (PPG) has become a commodity. However, arriving at a reliable heart rate measurement in real time during daily activities is an open research problem. In this paper, we propose a method based on Weiner Filter, to estimate the correct HR values in the presence of motion, while being computationally efficient to be run on device. Results are presented on a public data set which prove the efficacy and efficiency of the proposed method.
How to Ease the Pain of Taking a Diagnostic Point of Care Test to the Market: A Framework for Evidence Development
Venue: Micromachines
Year: 2020

Bringing a diagnostic point of care test (POCT) to a healthcare market can be a painful experience as it requires the manufacturer to meet considerable technical, financial, managerial, and regulatory challenges. In this opinion article we propose a framework for developing the evidence needed to support product development, marketing, and adoption. We discuss each step in the evidence development pathway from the invention phase to the implementation of a new POCT in the healthcare system. We highlight the importance of articulating the value propositions and documenting the care pathway. We provide guidance on how to conduct care pathway analysis as little has been published on this. We summarize the clinical, economic and qualitative studies to be considered for developing evidence, and provide useful links to relevant software, on line applications, websites, and give practical advice. We also provide advice on patient and public involvement and engagement (PPIE) and on product management. Our aim is to help device manufacturers to understand the concepts and terminology used in evaluation of in vitro diagnostics (IVDs) so that they can communicate effectively with evaluation methodologists, statisticians, and health economists. Manufacturers of medical tests and devices can use the proposed framework to plan their evidence development strategy in alignment with device development, applications for regulatory approval, and publication.

Intelligent Support for Knowledge Sharing in Virtual Communities
Year: 2010

Virtual communities where people with common interests and goals communicate, share resources, and construct knowledge, are currently one of the fastest growing web environments. A common misconception is to believe that a virtual community will be effective when people and technology are present. Appropriate support for the effective functioning of online communities is paramount. In this line, personalisation and adaptation can play a crucial role, as illustrated by recent user modelling approaches that support social web groups. However, personalisation research has mainly focused on adapting to the needs of individual members, as opposed to supporting communities to function as a whole. In this research, we argue that effective support tailored to virtual communities requires considering the wholeness of the community and facilitating the processes that influence the success of knowledge sharing and collaboration. We are focusing on closely knit communities that operate in the boundaries of organisations or in the educational sector. Following research in organisational psychology, we have identified several processes important for effective team functioning which can be applied to virtual communities and can be examined or facilitated by analysing community log data. Based on the above processes we defined a computational framework that consists of two major parts. The first deals with the extraction of a community model that represents the whole community and the second deals with the application of the model in order to identify what adaptive support is needed and when. The validation of this framework has been done using real virtual community data and the advantages of the adaptive support have been examined based on the changes happened after the interventions in the community combined with user feedback. With this thesis we contribute to the user modelling and adaptive systems research communities with: (a) a novel framework for holistic adaptive support in virtual communities, (b) a mechanism for extracting and maintaining a semantic community model based on the processes identified, and (c) deployment of the community model to identify problems and provide holistic support to a virtual community. We also contribute to the CSCW community with a novel approach in providing semantically enriched community awareness and to the area of social networks with a semantically enriched approach for modeling change patterns in a closely knit VC.
A global ocean acoustic observing network
Year: 2010

Passive and active acoustic measurements are effective and unique approaches to ocean observation. Both approaches have techniques that are well established and suitable for immediate deployment as part of an operational observing system. Many of these techniques exploit the remarkable ability of lowfrequency sounds to traverse great distances in the ocean. Passive acoustic measurements of natural or man made sounds are made for diverse purposes ranging from assessing the environmental impact of human activities, to geophysics, to monitoring changes in biodiversity in response to climate change. Active acoustic systems are employed for tracking instruments and acoustic tomography. Tomography has a role in the ocean observing system that is complementary to altimetry and profiling floats, particularly in the context of data assimilation and ocean modeling. Modest systems of acoustic receivers and sources deployed across ocean basins can make cost effective, sustained observations of a variety of ocean processes.
Analyzing challenging aspects of IPv6 over IPv4
Year: 2020

The exponential expansion of the Internet has exhausted the IPv4 addresses provided by IANA. The new IP edition, i.e. IPv6 introduced by IETF with new features such as a simplified packet header, a greater address space, a different address sort, improved encryption, powerful section routing, and stronger QoS. ISPs are slowly seeking to migrate from current IPv4 physical networks to new generation IPv6 networks. The move from actual IPv4 to software based IPv6 is very sluggish, since billions of computers across the globe use IPv4 addresses. The configuration and actions of IP4 and IPv6 protocols are distinct. Direct correspondence between IPv4 and IPv6 is also not feasible. In terms of the incompatibility problems, all protocols can co exist throughout the transformation for a few years. Compatibility, interoperability, and stability are key concerns between IP4 and IPv6 protocols. After the conversion of the network through an IPv6, the move causes several issues for ISPs. The key challenges faced by ISPs are packet traversing, routing scalability, performance reliability, and protection. Within this study, we meticulously analyzed a detailed overview of all aforementioned issues during switching into ipv6 network.
Loving Machines: Theorizing Human and Sociable Technology Interaction
Venue: HRPR
Year: 2010

Today, human and sociable technology interaction is a contested site of inquiry. Some regard social robots as an innovative medium of communication that offer new avenues for expression, communication, and interaction. Other others question the moral veracity of human robot relationships, suggesting that such associations risk psychological impoverishment. What seems clear is that the emergence of social robots in everyday life will alter the nature of social interaction, bringing with it a need for new theories to understand the shifting terrain between humans and machines. This work provides a historical context for human and sociable robot interaction. Current research related to human sociable technology interaction is considered in relation to arguments that confront a humanist view that confine 'technological things' to the nonhuman side of the human/nonhuman binary relation. Finally, it recommends a theoretical approach for the study of human and sociable technology interaction that accommodates increasingly personal relations between human and nonhuman technologies.
A Hybrid MPI/OpenMP Parallelization of $K$ Means Algorithms Accelerated Using the Triangle Inequality
Venue: IEEE Access
Year: 2019

The standard formulation of the <inline formula> <tex math notation="LaTeX"$K$ /tex math>/inline formula> means clustering (Lloyd's method) performs many unnecessary distance calculations. In this paper, we focus on four approaches that use the triangle inequality to avoid unnecessary distance calculations. These approaches are Drake's, Elkan's, Annulus, and Yinyang algorithms. We propose a hybrid MPI/OpenMP parallelization of these algorithms in which the dataset and the corresponding data structures storing bounds on distances are evenly divided among MPI processes. Then, in the assignment step of a <inline formula> <tex math notation="LaTeX"$K$ /tex math>/inline formula> means iteration, each MPI process computes the assignment of its portion of data using OpenMP threads. In the update step of the iteration, the cluster centroids are computed using a hierarchical all reduce operation. In the computational experiments, we compared the strong scalability of these four algorithms with the scalability of Lloyd's algorithm, parallelized using the same approach. The results indicate that all four algorithms maintain an advantage in computing time over Lloyd's algorithm. A comparison with two software packages, whose sources are publicly available, in the same computing environment, shows that our implementations are more efficient.
