Plan de accion para la transformacion de la educacion superior en America Latina y el Caribe
Year: 2018

Todo intento de transformacion de los sistemas e instituciones de educacion superior (IES) de America Latina y el Caribe, debe tener en cuenta que, por sus origenes, por su historia, por su localizacion y sus obietivos fundamentales, ellos presentan una gran diversidad que necesita ser reconocida y atendida. Como consecuencia, las instituciones requieren estrategias particulares de acuerdo con su etapa de desarrollo y sus metas futuras. Por ello, el proceso impulsado por UNESCO a partir de 1994 a traves de su Centro Regional para la educacion Superior en America Latina y el Caribe (CRESALC) se ha centrado en promover investigaciones comparativas, proveer espacios de dialogo, reflexion y debate entre los actores principales de la educacion superior en America Latina y el Caribe, e ir consensuando paulatinamente lineamientos estrategicos y obietivos regionales que puedan servir de guia a las instituciones en su proceso de gestar su transformacion particular. Entre las actividades realizadas por UNESCO vale destacar la Conferencia Regional sobre Politicas y Estrategias para la Transformacion de la Educacion Superior en America latina y el Caribe, celebrada en La Habana, Cuba, en noviembre de 1996. En su fase preparatoria se movilizaron mas de 4,000 personas vinculadas a la educacion superior y la gestion gubernamental de la region, mediante la realizacion de 36 reuniones a escala nacional y subregional. La riqueza documental generada tanto por los seminarios preparatorios como por la propia Conferencia, a la que asistieron 688 personas, constituye el mas importante acervo de que disponemos hoy para comprender los problemas, desafiosy posibilidades de la educacion superior en America Latina y el Caribe.
From occultism to hybrid Sufism the transformation of an Islamic hybrid spiritual group in contemporary Indonesia
Year: 2014

This paper discuses transformation of an Islamic Hybrid Spiritual group, the Bhakti Nusantara (literally means 'devotion to nation' from spiritualitas kasar [rough spirituality] of occult based spirituality to the finer spirituality [spiritualitas alus] which is linked to Sufi spiritual practices. Based on my field work in Yogyakarta, in 2009 and 2010, the paper explains sociological context of group's institutional and spiritual transformation amid contemporary Islamic revival and modernizing process of the country. It then argues that the transformation of the group was driven by the logic for presenting spiritual heritages that are practically appropriate for modern life and which also fit religiously with orthodox Islam. Both the institutional transformation and the change of spiritual orientation of the group mark BN, as a hybrid spiritual group, to actively involve in the opportunities of modernity, instead of resisting the challenges and pressures of modern life. Tulisan ini membahas proses transformasi dalam sebuah kelompok spiritualitas hybrida bernama Bhakti Nusantara (BN) dari "spiritualitas kasar" yang terkait IJIMS, Indonesian Journal of Islam and Muslim Societies, Volume 4, Number 1, June 2014: 81 104 82 dengan praktik klenik kejawen ke spiritualitas halus yang berbasis pada praktif tasawuf/Sufisme. Berdasar hasil riset lapangan di Yogyakarta tahun 2009 dan 2010, paper ini mencoba mengungkap konteks sosiologis dari transformasi kelembagaan maupun perubahan orientasi spiritualnya di tengah proses modernisasi dan kebangkitan Islam di Indonesia pasca reformasi. Transformasi dari spiritualitas kasar ke spiritualitas halus ini terjadi, diantaranya, dilatari oleh nalar untuk menyesuaiakn praktik dan layanan spiritual agar lebih sesuai dengan alam pikiran dan kebutuhan manusia modern dan praktik spiritual yang tidak bertentangan dengan ortodoksi keberagaan umat Islam. Transformasi yang terjadi di BN telah mengantarkan kelompok spiritualitas hibrida ini untuk menawarakan formula spiritual yang lebih pro aktif dalam menyongsong peluang yang ditawarkan modernitas, bukan formula spiritualitas untuk melawan tantangan dan menghidnari tekanan kehidupan modern.
QCD phase structure at finite temperature and density
Year: 2020

We discuss the phase structure of QCD for Nf=2 and Nf=2+1 dynamical quark flavors at finite temperature and baryon chemical potential. It emerges dynamically from the underlying fundamental interactions between quarks and gluons in our work. To this end, starting from the perturbative high energy regime, we systematically integrate out quantum fluctuations toward low energies by using the functional renormalization group. By dynamically hadronizing the dominant interaction channels responsible for the formation of light mesons and quark condensates, we are able to extract the phase diagram for mB/T6. We find a critical endpoint at (TCEP,mBCEP)(107,635) MeV. The curvature of the phase boundary at small chemical potential is k=0.0142(2) computed from the renormalized light chiral condensate Dl,R. Furthermore, we find indications for an inhomogeneous regime in the vicinity and above the chiral transition for mB417 MeV. Where applicable, our results are in very good agreement with the most recent lattice results. We also compare to results from other functional methods and phenomenological freeze out data. This indicates that a consistent picture of the phase structure at finite baryon chemical potential is beginning to emerge. The systematic uncertainty of our results grows large in the density regime around the critical endpoint and we discuss necessary improvements of our current approximation toward a quantitatively precise determination of QCD phase diagram.
Trading sleep for results
Year: 2017

Like so many stories from graduate school, this is a familiar one: After a week of running reactions and columns, I had stayed late in the laboratory to start one more reaction with a precious synthetic intermediate. My plan was to head home afterwards for some hard won sleep, then come back to the laboratory, refreshed and ready to take that material onto its next synthetic step. After setting up the reaction, I pedaled home in the dark. It wasn't ten seconds after my head hit the pillow that I realized what I had done: I had loaded all of my intermediate into my reaction and forgotten one of the key starting materials. The reaction was ruined, and it was a costly mistake. I learned an important lesson that night: Putting in long hours doesn't always pay off. Of course, rather than getting some sleep and starting fresh the next morning,
"Rutherford's Experiment" on Alpha Particles Scattering: The Experiment That Never Was.
Year: 2018

The so called Rutherford's experiment, as it is outlined in many physics textbooks, is a case in point of the flaws around the history at the educational level of one of the decisive event of modern physics: the discovery that the atom has a nucleus. This paper shows that this alleged experiment is a very approximate and very partial synthesis of a series of different particle scattering experiments, starting with that carried out by Rutherford in 1906 and ending with Geiger and Marsden's 1913 experiments.
Neural network parameter optimization and fault diagnosis based on orthogonal experiments
Venue: 2010 8th World Congress on Intelligent Control and Automation
Year: 2010

The wavelet analysis and neural network for fault diagnosis system in practice has become a hot research topic in the fields of pattern recognition system in recent years. Acoustic emission technology is used for vibrating screen's fault diagnosis in this paper. The energy feature vectors of signals extracted by use of wavelet packet analysis is regarded as neural network input vectors, and the system parameters are optimized by means of orthogonal test method. The results show that the detection method can effectively determine the working state of the vibrating screen to achieve real time monitoring.
Fatores associados a polifarmacia em idosos institucionalizados
Year: 2010

Polypharmacy is an important issue in the elderly care. The ones under institutionalization have higher risks, due to their comorbidities, frailty and dependency. This study aims to evaluate the factors associated with polypharmacy in institutionalized elderly.  A retrospective, crosssectional study was carried out. All medical charts of patients aged 60 years old or more in a huge public nursing home were evaluated. A protocol containing socio demographic data, number and types of diseases, number of drugs, types of drugs, functional status and time of institutionalization were analyzed. Through statistical analysis, these factors were linked or not to polypharmacy.  The final sample comprised 209 patients, 73.2% women, average age of 75.9 years and with an institutionalized time of 95.3 months. The most prevalent diseases were: arterial hypertension 67.9% dementia 36.8% and stroke or head trauma sequelae 33.9% In this study, the associated factors related to polypharmacy in nursing home residents were: lack of cognitive deficit, (OR=3,61 IC: 1,96 6,65) use of cardiovascular drugs (OR=0,22 IC: 0,11 0,44) use of gastrointestinal and metabolic drugs(OR=0,38 IC: 0,21 0,67) five or more diagnosis (OR=1,90 IC: 1,08 3,33) institutionalized time between 12 and 23 months (OR:0,32 IC: 0,11 0,91) and greater dependency in Katz scale (OR: 1,90 IC:1,07 3,22) There were no relationship with age, sex, psychiatric drugs and diagnosis of stroke or head trauma sequelae.  It follows that institutionalized elderly have different aspects as compared to outpatients or community, with major factors related to functionality and time of institutionalization than to age and sex.
Repercusiones de las clases virtuales en los estudiantes universitarios en el contexto de la cuarentena por COVID 19: El caso de la PUCP
Year: 2020

Desde la aparicion de la pandemia de la COVID 19, han ocurrido cambios drasticos en los habitos de vida de los seres humanos. La educacion universitaria no es ajena a las diversas reformas que la coyuntura actual demanda. Por ello, muchas de ellas adaptaron sus clases a una modalidad netamente virtual. En ese contexto, la presente investigacion busca analizar las repercusiones en la salud mental de los estudiantes de la Pontificia Universidad Catolica del Peru (PUCP) en el marco de la cuarentena por COVID 19. Para ello, recoge las percepciones de una muestra de 74 estudiantes de la facultad de Estudios Generales Letras en base a su experiencia con las clases no presenciales en tiempos de pandemia. La muestra se dividio en dos grupos: el primer grupo, con adecuados recursos tecnologicos y el segundo grupo, carente de tecnologias de calidad. Los resultados muestran que la principal consecuencia para el primer grupo es el estres a causa de la sobrecarga academica, y para el segundo, aparte del estres, la frustracion y la desercion universitaria.

Prevalence of noncommunicable disease risk factors among the Kani tribe in Thiruvananthapuram district, Kerala
Venue: Indian heart journal
Year: 2018

Noncommunicable Disease (NCD) risk factors are on the rise and often linked to the adoption of modern lifestyles. This study explores NCD risk factors in a rapidly modernising indigenous population in Kerala, the Kani tribe.  A representative sample of 298 adults of the Kani tribe in Thiruvananthapuram district was studied using the WHO stepwise framework for surveillance of NCD risk factors. Descriptive, bivariate and multivariable analysis were done using the R statistical package.  Prevalence of hypertension (48.3% use of tobacco (81.5% and alcohol consumption (36.2% were found to be higher in the Kani tribe compared to the general population in Kerala. Abdominal obesity (22.1% is found to be higher in Kani tribes compared to other tribal groups in India. The physical inactivity level (9.7% was similar to urban Kerala and higher than many other tribes in India. Hypertension was scientifically associated (p 0.05) with higher age, male sex, low education levels, and tobacco intake among them. On multivariable analysis, age and alcohol consumption were found to be the prominent risk factors for hypertension and high education level was found to be a protective factor.  The major modifiable NCD risk factors were found to be higher among the people of the Kani tribe compared to the general population in Kerala. Physical inactivity level was comparable to urban Kerala, and obesity rates were higher than many other tribal communities in India. The findings warrants targeted action in these vulnerable communities for effective control of the noncommunicable epidemic.
Using ecological models to assess ecosystem status in support of the European Marine Strategy Framework Directive
Year: 2015

The European Union's Marine Strategy Framework Directive (MSFD) seeks to achieve, for all European seas, "Good Environmental Status" (GEnS) by 2020. Ecological models are currently one of the strongest approaches used to predicting and understanding the consequences of anthropogenic and climate driven changes in the natural environment. We assess the most commonly used capabilities of the modelling community to provide information about indicators outlined in the MSFD, particularly on biodiversity, food webs, non indigenous species and seafloor integrity descriptors. We built a catalogue of models and their derived indicators to assess which models were able to demonstrate: (1) the linkages between indicators and ecosystem structure and function and (2) the impact of pressures on ecosystem state through indicators. Our survey identified 44 ecological models being implemented in Europe, with a high prevalence of those that focus on links between hydrodynamics and biogeochemistry, followed by end to end, species distribution/habitat suitability, bio optical (remote sensing) and multispecies models. Approximately 200 indicators could be derived from these models, the majority of which were biomass and physical/hydrological/chemical indicators. Biodiversity and food webs descriptors, with ~49% and ~43% respectively, were better addressed in the reviewed modelling approaches than the non indigenous species (0.3% and sea floor integrity ~8% descriptors. Out of 12 criteria and 21 MSFD indicators relevant to the abovementioned descriptors, currently only three indicators were not addressed by the 44 models reviewed. Modelling approaches showed also the potential to inform on the complex, integrative ecosystem dimensions while addressing ecosystem fundamental properties, such as interactions between structural components and ecosystems services provided, despite the fact that they are not part of the MSFD indicators set. The cataloguing of models and their derived indicators presented in this study, aim at helping the planning and integration of policies like the MSFD which require the assessment of all European Seas in relation to their ecosystem status and pressures associated and the establishment of environmental targets (through the use of indicators) to achieve GEnS by 2020.
Controllability of epoxy equivalent weight and performance of hyperbranched epoxy resins
Venue: Composites Part B: Engineering
Year: 2019

Hyperbranched epoxy resins (HERs) is a group of thermoset resins which can be used to improve specifically the toughness and strength of popular diglycidyl ether of bisphenol A (DGEBA) However, a relationship between the epoxy equivalent weight (EEW) of HERs and the level of property improvement has not been established due to the difficulty to control their EEW. Here we report the synthesis of a series of hyperbranched epoxy resins with different EEW (EHBP n) through thiol ene click reaction between thiol ended hyperbranched polyesters and allylglycidyl ether. The rheological properties of the uncured EHBP n/DGEBA blends are determined by viscosity and modulus changes, and are directly affected by the EEW of EHBP n. Moreover, the EEW of EHBP n also can tune the glass transition temperature and mechanical performances of the cured EHBP n/DGEBA composites, and these properties first increased and then decreased with a decrease in the EEW of EHBP n. At 9 wt of EHBP 6, the improvements on the tensile, flexural, impact and adhesive strengths are 38.9% 35.3% 158.6% and 96.2% respectively, compared with those of cured DGEBA. This result will give a basic guidance for obtaining epoxy resins with various performance.
Parallelizing Multimodal Background Modeling on a Low Power Integrated GPU
Venue: J. Signal Process. Syst.
Year: 2017

Background modeling techniques for embedded computer vision applications must balance accuracy, speed, and power. Basic background modeling techniques run quickly, but their accuracy is not sufficient for computer vision problems involving dynamic background. In contrast, adaptive background modeling techniques are more robust, but run more slowly. Due to its high inherent fine grain parallelism, robust adaptive background modeling has been implemented on GPUs with significant performance improvements over CPUs. However, these implementations are infeasible in embedded applications due to the high power ratings of the targeted general purpose GPU platforms. This paper focuses on exploiting fine grain data parallelism and optimizing memory access patterns to target a low cost adaptive background modeling algorithm multimodal mean (MMM) to a low power GPU with thermal design power (TDP) of only 12 watts. The algorithm has comparable accuracy with the Gaussian mixture model (GMM) algorithm, but less computational and memory cost. It achieves a frame rate of 392 fps with a full VGA resolution (640x480) frame on the low power integrated GPU NVIDIA ION. This is a 20x speed up of the MMM algorithm compared to the embedded CPU platform Intel Atom of comparable TDP. In addition, the MMM algorithm attains a 5 6x speed up over the GMM implementation on the ION GPU platform.
Modeling the Worldwide Spread of Pandemic Influenza: Baseline Case and Containment Interventions
Venue: PLoS medicine
Year: 2007

The highly pathogenic H5N1 avian influenza virus, which is now widespread in Southeast Asia and which diffused recently in some areas of the Balkans region and Western Europe, has raised a public alert toward the potential occurrence of a new severe influenza pandemic. Here we study the worldwide spread of a pandemic and its possible containment at a global level taking into account all available information on air travel.  We studied a metapopulation stochastic epidemic model on a global scale that considers airline travel flow data among urban areas. We provided a temporal and spatial evolution of the pandemic with a sensitivity analysis of different levels of infectiousness of the virus and initial outbreak conditions (both geographical and seasonal) For each spreading scenario we provided the timeline and the geographical impact of the pandemic in 3,100 urban areas, located in 220 different countries. We compared the baseline cases with different containment strategies, including travel restrictions and the therapeutic use of antiviral (AV) drugs. We investigated the effect of the use of AV drugs in the event that therapeutic protocols can be carried out with maximal coverage for the populations in all countries. In view of the wide diversity of AV stockpiles in different regions of the world, we also studied scenarios in which only a limited number of countries are prepared (i.e. have considerable AV supplies) In particular, we compared different plans in which, on the one hand, only prepared and wealthy countries benefit from large AV resources, with, on the other hand, cooperative containment scenarios in which countries with large AV stockpiles make a small portion of their supplies available worldwide.  We show that the inclusion of air transportation is crucial in the assessment of the occurrence probability of global outbreaks. The large scale therapeutic usage of AV drugs in all hit countries would be able to mitigate a pandemic effect with a reproductive rate as high as 1.9 during the first year; with AV supply use sufficient to treat approximately 2% to 6% of the population, in conjunction with efficient case detection and timely drug distribution. For highly contagious viruses (i.e. a reproductive rate as high as 2.3) even the unrealistic use of supplies corresponding to the treatment of approximately 20% of the population leaves 30% 50% of the population infected. In the case of limited AV supplies and pandemics with a reproductive rate as high as 1.9, we demonstrate that the more cooperative the strategy, the more effective are the containment results in all regions of the world, including those countries that made part of their resources available for global use.
A Hybridized Forecasting Method Based on Weight Adjustment of Neural Network Using Generalized Type 2 Fuzzy Set
Venue: Int. J. Fuzzy Syst.
Year: 2019

This paper proposes a hybridized forecasting method on weight adjustment of neural networks with back propagation learning using general type 2 fuzzy sets. Initialization of weights and their adjustment in neural network are important areas of research as it increases the computation speed to get the optimized result. Higher order fuzzy logic systems are able to deal with the high levels of uncertainties present in the majority of real world problems. Here, the concept of interval based zSlices has been used to obtain the general type 2 fuzzy weights for the neural network architecture. We implement this proposed methodology on benchmark Mackey Glass time series data (for \tau =17$$t=17) and present a comparison of the results obtained with our approach and those of the existing approaches. The method is also applied on enrollment data of University of Alabama, closing price index of Shenzhen stock exchange, closing price index of Shanghai stock exchange, Canadian lynx data, and the results are presented.
