Una educacion transformadora para El Salvador: propuesta y obstaculos para alcanzarla
Year: 2015

Este ensayo tiene dos propositos. Primero, exponer un punto de vista sobre el concepto educacion de calidad en relacion con la finalidad de la educacion salvadorena expresada en la Constitucion Politica de El Salvador. Se propone que una educacion de calidad sea entendida como aquella que procura la formacion de ciudadanos criticos y activos a partir del desarrollo del pensamiento critico, con lo cual se logre dar respuestas a los problemas sociales actuales. El segundo proposito es argumentar que en el presente existen serios obstaculos para que el Estado salvadoreno garantice una educacion transformadora a su poblacion tales como acceso limitado al sistema educativo, alta desercion escolar, preparacion docente limitada, asi como la falta de consenso de pais en torno a la educacion, poca inversion en la educacion e ideas reduccionistas que orientan los programas educativos gubernamentales unicamente a la competitividad laboral y la actualizacion tecnologica
Fast Mapping Verb Meaning From Argument Structure
Year: 2010

To examine lexical knowledge in children through a fast mapping task.  This study compared the performance of 60 African American English speaking and general American English speaking children between the ages of 4 and 6 years. They were presented with a comprehension task involving the fast mapping of novel verbs in 4 different argument structures (intransitive, transitive, transfer, and complement) The fast mapping task was developed to determine how children use syntactic cues to help fix the meaning of novel verbs.  The results indicated that both groups of children could fast map novel verbs at a relatively equivalent level.  The promise of fast mapping as an alternative method of measuring word knowledge in culturally and linguistically diverse populations is discussed.
Impact of 21 Gene Recurrence Score on Chemotherapy Decision in Invasive Ductal Carcinoma of Breast with Nodal Micrometastases
Venue: Cancer research and treatment official journal of Korean Cancer Association
Year: 2019

The purpose of this study was to investigate the effect of 21 gene recurrence score (RS) on predicting prognosis and chemotherapy decision in node micrometastases (N1mi) breast invasive ductal carcinoma (IDC)  Patients with stage T1 2N1mi and estrogen receptor positive IDC diagnosed between 2004 and 2015 were included. The associations of 21 gene RS with breast cancer specific survival (BCSS) chemotherapy decision, and benefit of chemotherapy were analyzed.  We identified 4,758 patients including 1,403 patients (29.5% treated with adjuvant chemotherapy. In the traditional RS cutoffs, 2,831 (59.5% 1,634 (34.3% and 293 (6.2% patients were in the low intermediate and high risk RS groups, respectively. In 3,853 patients with human epidermal growth factor receptor 2 (HER2) status available, most patients were HER2 negative disease (98.3% A higher RS was independently related to chemotherapy receipt, and 14.0% 47.7% and 77.8% of patients in the low intermediate and high risk RS groups received chemotherapy, respectively. The multivariate analysis indicated that a higher RS was related to worse BCSS (p 0.001) The 5 year BCSS rates were 99.3% 97.4% and 91.9% in patients with low intermediate and high risk RS groups, respectively (p 0.001) However, chemotherapy receipt did not correlate with better BCSS in low intermediate or high risk RS groups. There were similar trends using Trial Assigning Individualized Options for Treatment RS cutoffs.  The 21 gene RS does predict outcome and impact on chemotherapy decision of N1mi breast IDC. Large cohort and long term outcomes studies are needed to identify the effects of chemotherapy in N1mi patients by different 21 gene RS groups.
Uncovering urban human mobility from large scale taxi GPS data
Year: 2015

Taxi GPS trajectories data contain massive spatial and temporal information of urban human activity and mobility. Taking taxi as mobile sensors, the information derived from taxi trips benefits the city and transportation planning. The original data used in study are collected from more than 1100 taxi drivers in Harbin city. We firstly divide the city area into 400 different transportation districts and analyze the origin and destination distribution in urban area on weekday and weekend. The Density Based Spatial Clustering of Applications with Noise (DBSCAN) algorithm is used to cluster pick up and drop off locations. Furthermore, four spatial interaction models are calibrated and compared based on trajectories in shopping center of Harbin city to study the pick up location searching behavior. By extracting taxi trips from GPS data, travel distance, time and average speed in occupied and non occupied status are then used to investigate human mobility. Finally, we use observed OD matrix of center area in Harbin city to model the traffic distribution patterns based on entropy maximizing method, and the estimation performance verify its effectiveness in case study.
SOCIAL ENTREPRENEURSHIP AND CLASSICAL ENTREPRISE WITH SOCIAL RESPONSIBILITY ANALYSIS: ADVANTAGES AND DISADVANTAGES
Year: 2020

The article is devoted to the study of the concept of "social entrepreneurship" and "social business" amid rapid development and integration of classical entrepreneurship, its basic principles and business models. The authors identify the role of social issues and society as a motivating factor for the creation of social enterprises. Theoretical interpretation of the concepts of "traditional enterprise with social responsibility" "social entrepreneurship" "social business" has been given. The importance of business social responsibility and cooperation with social enterprises has been outlined. Based on the comparative analysis, the main differences and common features of a classic enterprise with social responsibility and social entrepreneurship have been identified. This allowed to highlight the advantages and disadvantages of each form of management. The world trend of social entrepreneurship development and the importance of introducing social responsibility for businesses have been determined. Five opportunities for the development of social entrepreneurship in Ukraine have been studied. It has been proved that the lack of social entrepreneurship regulatory framework is an obstacle to the development of social entrepreneurship and its consolidation as an innovative form of management. Analysis of the best country for the development of social entrepreneurship has been provided and the leading countries in the development of the form of management with social guidelines have been identified. It has been proved that the main objective of social entrepreneurship is to solve the problems of society, which is a priority in the activity, and to obtain certain benefits.
Learning Unsupervised Video Object Segmentation Through Visual Attention
Venue: 2019 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR)
Year: 2019

This paper conducts a systematic study on the role of visual attention in Unsupervised Video Object Segmentation (UVOS) tasks. By elaborately annotating three popular video segmentation datasets (DAVIS, Youtube Objects and SegTrack V2) with dynamic eye tracking data in the UVOS setting, for the first time, we quantitatively verified the high consistency of visual attention behavior among human observers, and found strong correlation between human attention and explicit primary object judgements during dynamic, task driven viewing. Such novel observations provide an in depth insight into the underlying rationale behind UVOS. Inspired by these findings, we decouple UVOS into two sub tasks: UVOS driven Dynamic Visual Attention Prediction (DVAP) in spatiotemporal domain, and Attention Guided Object Segmentation (AGOS) in spatial domain. Our UVOS solution enjoys three major merits: 1) modular training without using expensive video segmentation annotations, instead, using more affordable dynamic fixation data to train the initial video attention module and using existing fixation segmentation paired static/image data to train the subsequent segmentation module; 2) comprehensive foreground understanding through multi source learning; and 3) additional interpretability from the biologically inspired and assessable attention. Experiments on popular benchmarks show that, even without using expensive video object mask annotations, our model achieves compelling performance in comparison with state of the arts.
Pedagogies of experience: a case of the African American male teacher
Year: 2011

Numerous scholars have illustrated how African American teachers' past experiences provide them a philosophical vision committed to teaching for social and educational change for African American students. This article draws from this body of work by looking at the diverse ways five African American male teachers used their past experiences to shape their vision for working with African American male students. However, this article also extends this body of work by illustrating that while the teachers in this study had similar commitments to working with African American males, their varied life experiences and social locations provided them different sources of practical and philosophical knowledge. These findings illustrate the diversity of experiences these teachers drew from, thus troubling the common sense discourses that essentialize African American male teachers as one dimensional monolithic role models.
Modern diagnosis of GERD: the Lyon Consensus
Venue: Gut
Year: 2018

Clinical history, questionnaire data and response to antisecretory therapy are insufficient to make a conclusive diagnosis of GERD in isolation, but are of value in determining need for further investigation. Conclusive evidence for reflux on oesophageal testing include advanced grade erosive oesophagitis (LA grades C and D) long segment Barrett's mucosa or peptic strictures on endoscopy or distal oesophageal acid exposure time (AET) >6% on ambulatory pH or pH impedance monitoring. A normal endoscopy does not exclude GERD, but provides supportive evidence refuting GERD in conjunction with distal AET <4% and <40 reflux episodes on pH impedance monitoring off proton pump inhibitors. Reflux symptom association on ambulatory reflux monitoring provides supportive evidence for reflux triggered symptoms, and may predict a better treatment outcome when present. When endoscopy and pH or pH impedance monitoring are inconclusive, adjunctive evidence from biopsy findings (histopathology scores, dilated intercellular spaces) motor evaluation (hypotensive lower oesophageal sphincter, hiatus hernia and oesophageal body hypomotility on high resolution manometry) and novel impedance metrics (baseline impedance, postreflux swallow induced peristaltic wave index) can add confidence for a GERD diagnosis; however, diagnosis cannot be based on these findings alone. An assessment of anatomy, motor function, reflux burden and symptomatic phenotype will therefore help direct management. Future GERD management strategies should focus on defining individual patient phenotypes based on the level of refluxate exposure, mechanism of reflux, efficacy of clearance, underlying anatomy of the oesophagogastric junction and psychometrics defining symptomatic presentations.
Multiphase partial and selective dolomitization of Carnian reef limestone (Transdanubian Range, Hungary)
Year: 2014

Partially dolomitized carbonate successions provide a good opportunity to understand the commonly multistage process of dolomitization. Petrographic methods, fluid inclusion microthermometry and stable isotope measurements were applied to reconstruct the diagenetic evolution and dolomitization of a partially dolomitized Carnian reef limestone from the Transdanubian Range, Hungary. The diagenetic history began with reef diagenesis and formation of dolomite micro aggregates in microbial fabric elements; this was followed by the development of euhedral porphyrotopic dolomite crystals through overgrowths around the previously formed dolomite micro aggregates during the earliest burial stage. Increasing burial resulted in the extension of the dolomite patches via formation of finely crystalline replacement dolomite. From the Late Norian, when the Carnian reef carbonates reached the depth of 1*0 to 1*8 km, the diagenetic evolution continued in an intermediate to deep burial setting. Contemporaneously, an extensional regime was established, leading to fracturing. The progressive burial resulted in the recrystallization of the pre existing dolomite with increasing temperature, while saddle dolomite cement was precipitated in fractures. In connection with the Alpine Orogeny, intense denudation took place during the Late Cretaceous, accompanied by fracturing. Similar tectonically controlled denudation and fracturing occurred in several stages during the Cenozoic. As a result of these processes, the studied Carnian carbonates were raised to a near surface position or became subaerially exposed, leading to dedolomitization of the last dolomite phase and precipitation of calcite cement in cavities and fractures. This study revealed that by investigating partially and selectively dolomitized rock types, it is possible to document and understand those stages of the multiple dolomitization process which can barely be detected in the completely dolomitized rock bodies. Recognition of the dolomitization phases could provide the basis for the analysis of their relations with the depositional, diagenetic and tectonic processes, and stages of basin evolution.
Cloud DDoS Detection and Defense System using Complex Event Processing
Venue: 2021 5th International Conference on Intelligent Computing and Control Systems (ICICCS)
Year: 2021

Distributed Denial of Service attacks is the predominant targeted cyber attack on the cloud infrastructure which has now evolved as the persistent and more sophisticated attack. DDoS attack sources share the same bandwidth and communication channel of that of genuine flows. It is very essential to distinguish the attack and normal flows at the stream level for early diagnosis. The current security solutions for DDoS attack are still lacking in handling traffic from multiple attack sources and correlating the event patterns from the real time traffic. Hence, the proposed cloud based DDoS detection and defense system is designed to derive meaningful information about the DDoS security events in the spatio temporal domain by complex event processing method and security enforcement policies. The proposed system detects the various kind of DDoS attacks such as TCP SYN flood, TCP SYN ACK, LAND, UDP and ICMP flood and provides high detection accuracy and high alert reduction by correlating the cloud parameters such as source address, destination address, port and subnet. The defense system immediately acts on the attack sources to take remedial actions and protects the cloud from DDoS attacks.
Azithomycin as an adjunctive to non surgical treatment in comparison with doxycycline in chronic periodontitis patients: 2 months randomized clinical tria
Year: 2012

Antibiotic therapy can be used in very specific periodontal treatment situations such as in refractory cases of periodontal disease which is found to be more prevalent in smokers. The aim of study was to asses the clinical effect of systemic use of Azithromycin and Doxycycline as adjunctive to non surgical scaling and root planning in patients with chronic periodontitis.  The study participants were 21 adult male, divided to three groups. 1n: GI treated by non surgical root planning with systemic intake of Azithromycin of 500 mg once daily for three days only. In GII Doxycycline 100mg once daily was given for one week in addition to non surgical root planning while in the G III (control group) the patients were treated only by a routine scaling and root planning with out using any type of drug. .The periodontal parameters used are the following: Plaque index system(PLI) Gingival index (GI),Probing pocket depth (PPD) and Bleeding on probing (BoP)  The study based on three periodontal parameters to asses the results of study, first of which is plaque index and there was a significant low in all groups from the base line until the 4th visit while the bleeding on probing showed a highly significant difference between the groups whom take antibiotics as an adjunctive to a non surgical treatment and the group with out antibiotics. While for probing pocket depth the difference was only between the groups whom take Azithromycin and control group this difference was start in the 2nd visit until the last visit  Although both treatment strategies seemed to be a successful therapy, the adjunctive use of 500 mg azithromycin systemically enhanced the clinical results.
Working capital management and bank performance: empirical research of ten deposit money banks in Nigeria
Year: 2018

Working capital management is germane for the success of the banking industry in Nigeria, especially the current state of the sector, which is engulfed with the effect of the global decline in oil price that has resulted in non performing loans, deterioration of the bank asset quality, laying off of staff amongst others. This is one of the reasons why the profitability of the banking sector deeply depends on the efficient management of a bank's working capital. Therefore, the objective of this study is to examine how profitability of banks can be enhanced through the working capital management. To empirically carry out the analysis, panel data which consist of ten (10) deposit money banks in Nigeria for seven years (2010 2016) employing the panel fixed effect, panel random effect and the pooled OLS for the two models, which were used as proxies for bank profitability, which includes return on asset (ROA) and return on equity (ROE) to examine the best measure for bank profitability, with the indicators of working capital; net interest income, current ratio, profit after tax, and monetary policy rate. Results of the study showed that working capital management has a significant effect on the profitability of the selected banks and that return on asset is a better measure for bank profitability. Therefore, the study recommends that there should be a periodic review of the minimum capital base of the Nigerian deposit money banks so as to mitigate the effects of inflation and inculcate the consequence of time value of money, because the purchasing power of one (N1) naira or one $1) dollar today would not be sufficient to purchase what it can purchase today for tomorrow.

Dietary flaxseed oil rich in omega 3 suppresses severity of type 2 diabetes mellitus via anti inflammation and modulating gut microbiota in rats
Venue: Lipids in Health and Disease
Year: 2020

Type 2 diabetes mellitus (T2DM) is closely associated with hyperglycemia, abnormal lipid profiles, chronic low grade inflammation and gut dysbiosis. Dietary intervention plays a crucial role in the control of diabetes. Flaxseed oil (FO) a plant derived omega 3 (o 3) polyunsaturated fatty acids (PUFAs) is rich in a linolenic acid (ALA) which has been proved to benefit for chronic metabolic disease. However, the exact effects of dietary FO on T2DM remains largely unclear.  In the present study, SD rats were randomly allocated into four groups: pair fed (PF) with corn oil (CO) group (PF/CO) DM with CO group (DM/CO) PF with FO group (PF/FO) DM with FO group (DM/FO) A diabetic rat model was generated by a single intraperitoneal injection of streptozotocin nicotinamide (STZ NA) After 5 weeks of intervention, rats were euthanized and associated indications were investigated.  Dietary FO significantly reduced fasting blood glucose (FBG) glycated hemoglobin (GHb) blood lipid, plasma lipopolysaccharide (LPS) interleukin (IL) 1b, tumor necrosis factor (TNF) a, IL 6, IL 17A and malondialdehyde (MDA) compared to control group, respectively. Moreover, body mass (BM) and superoxide dismutase (SOD) in DM/FO group were dramatically increased respectively, compared with those in DM/CO group. But insulin (INS) and homeostasis model assessment of insulin resistance (HOMA IR) remained no significant difference between DM/CO group and DM/FO group. Sequencing analysis of gut microbiota showed a reduction in the relative abundance of Firmicutes and Blautia as well as a reduction in the ratio of Bacteroidetes Firmicutes in DM/FO group compared to DM/CO group. An elevation in the relative abundance of Bacteroidetes and Alistipes were detected in DM/FO group. Acetic acid, propionic acid and butyric acid belonging to short chain fatty acids (SCFAs) as gut microbiota metabolites, were dramatically increased after FO intervention. Correlation analysis revealed that the relative abundance of Firmicutes and Blautia were positively correlated with IL 1b, TNF a, IL 6, IL 17A or LPS, respectively. Additionally, Bacteroidetes and Alistipes were negatively correlated with LPS.  Taken together, dietary FO ameliorated T2DM via suppressing inflammation and modulating gut microbiota, which may potentially contribute to dietary control of diabetes.
