Applying DINEOF algorithm on cloudy sea surface temperature satellite data over the eastern Mediterranean Sea
Venue: Other Conferences
Year: 2013

Data Interpolating Empirical Orthogonal Functions (DINEOF) is a special technique which is based on Empirical Orthogonal Functions (EOF) in order to reconstruct missing data from satellite images. It is an innovative method, especially useful for filling in missing data from geophysical fields. Interesting examples could be clouds in sea surface temperature (SST) Past studies have shown that filtering the temporal covariance matrix allows to reduce spurious variability and therefore a more realistic data reconstruction can be obtained. There is also provision in the estimation of the error covariance of the reconstruction of the data. Moreover, the error fields can be obtained with some calculation rearrangement. Error fields reflect the data coverage structure and furthermore the covariance of the physical fields. Successful experiments on the Western Mediterranean encouraged the extension of the application of the method eastwards using similar experimental implementation. The present study summarizes the experimental work done, the implementation of the method and its ability in reconstructing the sea surface temperature field over the Eastern Mediterranean basin, and specifically over Levantine sea and Cyprus.
Guanxi vs Talent Acquisition: Evaluating the Effects of Guanxi Referrals in Sino Foreign Colleges
Year: 2019

The objective of the research is to investigate how teaching quality, courses delivered and their learning outcomes, student and staff satisfaction are affected when guanxi and non guanxi based staffs share the same class cohort and subject levels in the selected colleges for this study. The aim of the research is to show the implications, using a primary data inspected, thematically analysed findings of how these differences in quality control, lack of transparency in hiring and pay packages of guanxi and non guanxi based recruited staff members affect Chinese and non Chinese staff expectations and also overall image of foreign Universities who partner with colleges in mainland China.  The primary data is collected from interviews with a) candidates who have been hired through guanxi referrals, b) candidates who have been recruited in conventional ways with no social ties benefitting their hiring or position, c) learners from three foreign University partnered colleges in China. Considering the aim, the research strategy was adopted within a qualitative study research design that has applied a thematic analysis.  The investigation compares faculties who were hired on Guanxi basis and those who were not, and elucidates on a) A mismatch of staff expertise, courses delivered and learning outcomes, b) Absence of platform to share 'best practices' c) Lack of multi cultural learning ecosystems in staff rooms, d) Missed learning objectives and teacher student office hours, and e) Varying financial and moral incentives  There are clear challenges coming from guanxi led hired staff not working closely with non guanxi counterparts (even when they are teaching on the same course) the lack of access of staff profiles and inability of non guanxi staff to communicate with guanxi based staffs. The effects on the wider scale falls on student learning, image of foreign Universities, very high staff attrition rate, quality control measures and falling reputation of these colleges nationally within mainland China.
The bivariate probit model, maximum likelihood estimation, pseudo true parameters and partial identification
Venue: Journal of Econometrics
Year: 2019

This paper presents an examination of the finite sample performance of likelihood based estimators derived from different functional forms. We evaluate the impact of functional form miss specification on the performance of the maximum likelihood estimator derived from the bivariate probit model. We also investigate the practical importance of available instruments in both cases of correct and incorrect distributional specifications. We analyze the finite sample properties of the endogenous dummy variable and covariate coefficient estimates, and the correlation coefficient estimates, and we examine the existence of possible "compensating effects" between the latter and estimates of parametric functions such as the predicted probabilities and the average treatment effect. Finally, we provide a bridge between the literature on the bivariate probit model and that on partial identification by demonstrating how the properties of likelihood based estimators are explicable via a link between the notion of pseudo true parameter values and the concepts of partial identification.
Strategy Inventory for Language Learning ELL Student Form: Testing for Factorial Validity
Year: 2013

As the school aged English language learner (ELL) population continues to grow in the United States and other English speaking countries, psychometrically sound instruments to measure their language learning strategies (LLS) become ever more critical. This study adapted and validated an adult oriented measure of LLS (50 item Strategy Inventory for Language Learning [SILL] Oxford, 1990) for school aged ELLs in a sample of 1,057 elementary, middle, and high school students. The two stage validation process resulted in a shorter, 28 item version of the instrument, which we entitled the SILL ELL Student Form. The results of confirmatory factor analyses indicated a good fit to the validation (GFI .92, CFI .93, RMSEA .04, SRMR .05) and combined (GFI .95, CFI .95, RMSEA .03, SRMR .04) samples. The new measure has strong psychometric characteristics for use with school aged ELLs to diagnose their use of LLS in six distinct categories and is approximately half as long as the original SILL, which enhances it.s pragmatic value for busy classrooms. Additionally, this study addressed some of the theoretical issues with strategy categorization noted in the literature. Other applications of the measure for practice and research are discussed.
Palle di neve ed equazioni differenziali
Year: 2018

Mathematics teaching in recent decades has undergone radical changes: the purpose is no longer to be able to meticulously carry out long and demanding calculations; today, with the advent of computers, socalled "design" capabilities have become much more relevant, such as modeling real problems, knowing how to use various types of languages, interpreting statistical data and controlling the reasonableness of the calculations made using a computer. Specifically, this article presents a problem regarding the speed of melting a snowball; various models are presented describing the phenomenon and, for each of them, the solution of the relative differential equation is presented.
Dynamics of COVID 19 epidemics: SEIR models underestimate peak infection rates and overestimate epidemic duration
Venue: medRxiv
Year: 2020

Compartment models of infectious diseases, such as SEIR, are being used extensively to model the COVID 19 epidemic. Transitions between compartments are modelled either as instantaneous rates in differential equations, or as transition probabilities in discrete time difference or matrix equations. These models give accurate estimates of the position of equilibrium points, when the rate at which individuals enter each stage is equal to the rate at which they exit from it. However, they do not accurately capture the distribution of times that an individual spends in each compartment, so do not accurately capture the transient dynamics of epidemics. Here we show how matrix models can provide a straightforward route to accurately model stage durations, and thus correctly reproduce epidemic dynamics. We apply this approach to modelling the dynamics of a COVID 19 epidemic. We show that a SEIR model underestimates peak infection rates (by a factor of three using published parameter estimates based on the progress of the epidemic in Wuhan) and substantially overestimates epidemic persistence after the peak has passed.
The Newcastle Ottawa Scale (NOS) for Assessing the Quality of Nonrandomised Studies in Meta Analyses
Year: 2014

Nonrandomised studies, including case control and cohort studies, can be challenging to implement and conduct. Assessment of the quality of such studies is essential for a proper understanding of nonrandomised studies. The Newcastle Ottawa Scale (NOS) is an ongoing collaboration between the Universities of Newcastle, Australia and Ottawa, Canada. It was developed to assess the quality of nonrandomised studies with its design, content and ease of use directed to the task of incorporating the quality assessments in the interpretation of meta analytic results. A 'star system' has been developed in which a study is judged on three broad perspectives: the selection of the study groups; the comparability of the groups; and the ascertainment of either the exposure or outcome of interest for case control or cohort studies respectively. The goal of this project is to develop an instrument providing an easy and convenient tool for quality assessment of nonrandomised studies to be used in a systematic review.
Experimental Framework for Evaluation of ICT Impact on the Learning Process
Year: 2019

The world today is in a whole new dimension, consisting of new concepts and terms such as social networks, online communities, blogs and microblogs, emails, discussion forums, e books, and so on. All these instruments needs to be adapted to the learning process as well. The main goal of the paper is to propose the experimental framework for evaluation of ICT impact on the learning process. Two independent studies are provided to determinate the degree of ICT integration in the learning process: evaluation of the degree of knowledge and use of ICT by different target groups in the learning process before ICT integration in the learning process and evaluation of the degree of ICT impact in the learning process after its integration.
THE DIFFERENCE OF THE FATIGUE PERCEPTION, EXERCISEPULSE RATE, AND BLOOD LACTIC LEVEL AFTER DOING MULTY STAGE FITNESS TEST AND YO YO INTERMITTENDRECOVERY TEST
Year: 2016

Physical capacity is the initial of sport development. To support the achievement of the purpose of the exercise, needed an instrument evaluation to determine whether there is progression that occurs during exercise program is running. Along with the development of science and technology, a variety of physical capacity assessment instrument to emerge following modification. Interest modifications and developments are based on some adjustments, including physical characteristics; the basic skills of the sport movement; and the specific energy system. Multi Stage Fitness Test and Yo Yo Intermittent Recovery Test are two types of fitness test that often used to determine athlete's physical capacity, especially related to cardiorespiratory fitness. Although it has similar objectives, but at the time of execution, there are several differences. Objectives to be gained from this research are: knowing the difference in the achievement of the athlete's VO2max; the perception of fatigue; determine the increase of exercise pulse rate; determine levels of blood lactate athletes after Multi stage fitness test and Yo yo intermittent recovery test. The research design is quasi experimental research, studies conducted with quantitative approach. Subjects consisted of 13 Basketball athletes. Determination of the study subjects by purposive sampling. The subject of research is basketball athletes who have followed an intensive training program for at least six months. Basketball men's team Senior High School 4 Yogyakarta already has many achievements as a junior athlete at the championship on regional and national level. The results showed: the characteristics of the subjects based on the mean age was 17 years, mean body weight 69 kilograms, and the average height of 175 cm. The result of the athlete's VO2max using multistage fitness test lower than Yo yo intermittent recovery test, the athlete's perception of fatigue multistage fitness test lower than Yo yo intermittent recovery test. Increased exercise pulse rate athletes to Multi stage fitness test lower than Yo yo intermittent recovery test. Increased levels of blood lactate athletes after a multistage fitness test lower than Yo yo intermittent recovery test. Based on the description of the results, it can be concluded that the intensity of Yo yo intermittent recovery test is higher, because psychologically athletes perceive (use: The Borg Rating of Perceived Exertion/RPE scale) this test is needed high exertion, and physically athletes increased exercise pulse rate and blood lactate higher than after do Multistage fitness test. But instead, the result of the athlete's VO2max higher when measured by Yo yo intermittent recovery test compared Multi stage fitness test.
Multiperspective Bus Route Planning in a Stackelberg Game Framework
Year: 2020

Bus route planning is a challenging task due to multiple perspective interactions among passengers, service providers, and government agencies. This paper presents a multidimensional Stackelberg game based framework and mathematical model to best trade off the decisions of multiple stakeholders that previous literature rarely captures, i.e. governments, service providers, and passengers, in planning a new bus route or adjusting an existing one. The proposed model features a bilevel structure with the upper level reflecting the perspective of government agencies in subsidy allocation and the lower level representing the decisions of service providers in dispatching frequency and bus fleet size design. The bilevel model is framed as a Stackelberg game where government agencies take the role of "leader" and service providers take the role of "follower" with social costs and profits set as payoffs, respectively. This Stackelberg game based framework can reflect the decision sequence of both participants as well as their competition or collaboration relationship in planning a bus route. The impact of such decisions on the mode and route choices of passengers is captured by a Nested Logit model. A partition based bisection algorithm is developed to solve the proposed model. Results from a case study in Shanghai validate the effectiveness and performance of the proposed model and algorithm.
Clustering around latent variables approach to detect panel disagreement in three way tea sensory evaluation
Year: 2020

Sensory evaluation plays a remarkable role in maintaining the quality standards of beverages such as tea. The quality, which determines the price of tea, is evaluated by professional tea tasters. Uncertainty and vagueness of sensory evaluation has been a serious issue in selection of good quality tea. An issue existing when analyzing sensory data to detect panel disagreement is that data of three dimensional (three way) or higher are often reduced to two way data. Present study aimed to investigate the possibility of using Clustering around Latent Variables for three way data (CLV3W) method to detect panel disagreement in sensory data of Sri Lankan tea. A three way data set, 8 tea tastersx 13 tea growing regionsx6 attributes, for each month with four replicates (4 factories per region) for a period of one calendar year were used for the study. When CLV3W analysis was performed separately for each month data, it was found two clusters (two latent components) exist for the data. Attribute loadings of colour and strength indicated that they are represented by the first latent component, and those loadings for brightness, flavour, aroma, and quality indicated that they are represented by the second component. Region scores for the two components revealed grouping of regions indicating some regions have similar tea quality attributes. Assessor weights varied across latent components and months. However, by examining assessor weights it was possible to identify assessors those who were in agreement and those who were in disagreement for each component. This finding demonstrated the fact that certain assessors are more sensitive to certain attributes and thus in order to detect tea with certain attributes, appropriate assessors can be employed. Therefore, CLV3W method is a useful method to detect disagreement between assessors, especially in 3 way data, and it can effectively be used when selecting assessors for sensory evaluation.
CONTRIBUTION OF ILIOPSOAS AND QUADRATUS LUMBORUM MUSCLE SIZE ON LONG DISTANCE RUNNERS
Year: 2013

A hypertrophy of psoas muscle (PM) is assigned to be one of the major determinants for sprint running [2] Moreover, the erector spinae and quadratus lumborum muscles related to the sprint performance  These results suggest that higher sprint performance require the stabilization of the trunk lateral movement. The main function of PM is to flex the thigh on the pelvis, but also counteract as lateral flexion of the lower vertebral column. The functions of quadratus lumborum (QL) was considered as lateral flexion of lumbar spine. Therefore, activating unilateral PM with complementary activating contra lateral QL can stabilize the lumbar spine during running.
An Entropy Based Technique for Conferences Ranking
Venue: Data Management, Analytics and Innovation
Year: 2019

Ranking of conferences is carried out to guide the researchers so as to publish their work in top level venues. Existing works are needed to be improved in regard to accuracy. In this paper, we have proposed a ranking technique of conference papers named as influence language model (InLM) It uses entropy to calculate score for the purpose of ranking. It identifies level of the paper as well as level of the conference based on entropy score. Experiments have been performed on bigger dataset. The results reflect better position in comparison to the existing systems.
The Efficiency and Performance of Porous Film Containing Freshness Maintenance Ingredients
Year: 2009

To identify effective food packaging compounds that could significantly affect the freshness of stored food, the efficiency and performance of porous polypropylene film containing mustard oil as a freshness maintenance ingredient was studied by GC MS analysis and storage testing of bread. AITC (allyl isothiocyanate) emitting properties of films impregnated with mustard oil were evaluated by GC MS. AITC was extracted from mustard oil, and used as a vapor as an effective antimicrobial agent. Films were prepared under four different conditions (the film types were abbreviated 25SF1, 25SF2, 50LF, and IAF) and the amounts of AITC inside vinyl packs constructed using the four films were measured. The results showed that the 25SF2 film (width 25 mm, length 20 cm) yielded a greater amount of AITC than did the 50LF film (width 50 mm, length 20 cm) We confirmed that the amount of gas emission showed better between layer and layer of the film side than the internal film. In storage testing using various films at for 25 days, 25SF2 film provided excellent preservation of bread compared with 50LF film. This was in line with the fact that 25SF2 film yielded the highest amount of AITC. Emission capacities AITC of 2 cm film were measured using bottles various volumes (43 mL, 500 mL, 1000 mL) and both closed and open systems. The AITC content of the film in 43 mL bottle was much higher than that yielded by other films in the closed system, and AITC was rapidly emitted, with relatively low residual gas emission after 4 days in an open system. Mustard oil is a useful freshness maintenance ingredient hence, analysis of AITC emission kinetics from various films were helpful to develop films with optimal antimicrobial effects, and will allow application of such films in food packaging systems.
Effect of whole body hypothermia on inflammation and surfactant function in asphyxiated neonates
Venue: European Respiratory Journal
Year: 2014

T o the Editor: Hypothermia has become an evidence based treatment for neonates with hypoxic ischaemic encephalopathy (HIE)  The usefulness of hypothermia is due to several mechanisms and among these the reduction in inflammation seems to play a relevant role [2, 3] When applied as whole body hypothermia (WBH) cooling may affect other organs as well. Recent data showed better respiratory outcomes and trends towards lower inflammation in WBH treated preterm lambs  suggesting its possible usefulness to reduce lung injury through the modulation of the inflammatory pathway. By contrast, experiments with hibernating animals have shown that temperature induces significant adaptive changes to the surfactant composition and structure  Nevertheless, no data are currently available in humans. Two case reports have recently described an infant [6] and an adult [7] with severe lung injury, whose ventilation had been facilitated by concurrent hypothermia. Since hypothermia is an accepted therapy only for HIE, we designed a preliminary translational study to investigate the effect of WBH on inflammation and surfactant status in neonates with HIE unaffected by any pulmonary injury. Eligible babies were neonates with HIE who required WBH according to TOBY (total body hypothermia trial) criteria  Control babies were normothermic neonates matched for gestational age and SNAPPE II (Score for Neonatal Acute Physiology and Perinatal Extension II) score, born within 2 months of the HIE cases and needing intubation for surgical procedures during the first day of life. Both cases and controls had to be free from any pulmonary disease and fulfil the following criteria: 1) normal chest radiograph and auscultation; 2) inspiratory oxygen fraction of 0.21 to achieve arterial oxygen saturation =95% 3) normal amniotic fluid; 4) no signs of infection; and 5) no congenital lung disease or complex
