Implicaciones en la gestion estrategica de las empresas de la integracion de los sistemas de gestion de la calidad, medio ambiente y seguridad y salud laboral, basados en estandares internacionales. El caso de ecuador
Year: 2019

El proposito de esta investigacion es el de estudiar las consecuencias que se derivan en la gestion estrategica de las organizaciones ecuatorianas, en un proceso de integracion de los sistemas de gestion de Calidad, Medio Ambiente y Seguridad y Salud Laboral, basados en estandares internacionales. Con el fin de lograr encontrar la evidencia empirica de la experiencia particular de dichas organizaciones, se aplica un metodo deductivo hipotetico que parte en primer lugar del analisis del soporte teorico asi como del estudio de los sistemas de gestion certificables mas ampliamente implantados a nivel mundial (ISO 9001, ISO 14001 y OHSAS 18001, actualmente en proceso de migracion hacia la ISO 45001) junto con los procesos mas habitualmente utilizados en su integracion. Posteriormente, se lleva a cabo un trabajo de campo que por una parte recoge la evidencia empirica a traves de un cuestionario semiestructurado aplicado a organizaciones ecuatorianas, para mas tarde y, mediante su analisis, poner de manifiesto la realidad existente en dicho pais sudamericano. Es necesario indicar a este respecto que actualmente dicho pais cuenta con unas tasas de certificacion de sistemas de gestion relativamente bajas. Las hipotesis planteadas fueron contrastadas estadisticamente y los resultados obtenidos indican que, al igual que las organizaciones del resto del mundo, las organizaciones ecuatorianas tambien perciben importantes beneficios de la integracion de los sistemas de gestion, tanto a nivel interno como externo. En la presente tesis doctoral se han identificado factores de exito que han contribuido a este proposito y ayudado a las organizaciones a alcanzar la deseada sostenibilidad en el mercado global a traves del incremento de su productividad, la satisfaccion de sus clientes y la mejora de su imagen en el mercado. Finalmente, es preceptivo indicar una vez llegado a este punto, el hecho de que esta experiencia es pionera en su campo. A conocimiento de la autora no existe ninguna publicacion cientifica donde se aborde el tema y se presenten resultados concluyentes de la realidad encontrada en las organizaciones ecuatorianas que participaron en la investigacion, proporcionando asi un conocimiento empirico de un pais representativo de la situacion que esta aconteciendo en Latinoamerica.
Graphene 2019 June 25 28 2019 Rome Italy Graphene black phosphorus photodetectors
Year: 2019

Heterostructures can be assembled from liquid phase exfoliated (LPE) layered materials (LMs)  via inkjet printing with tens m  resolution and controllable thickness  to make photodetectors (PDs)  However, LPE materials are unfavourable compared to chemical vapor deposited and mechanically exfoliated LMs, due to the presence of traps  which results in low responsivities ~mA/W  Here, we fabricate printable PDs based on graphene and black phosphorus (BP) inks  showing high responsivity >300A/W) and broadband (0.4 2.8 m) detection  LPE BP is used due to its broadband optical absorption (400 3500nm)  and its tuneable layer dependent direct bandgap  Photoexcited holes from BP are injected into graphene, leaving behind uncompensated electrons, resulting in photogating. We achieve a photoconductive gain (ratio of carrier life time measured from the device response time to transit time [4]~107 ,broadband (400 2800nm) and fast ~50ms) response time. The dark current shows a 1/f component, with a noise equivalent power~1.88x10 10W/Hz, and a detectivity~107 Jones. The responsivity is at least three orders of magnitude higher than previously reported ink jet printed BP PDs operating at the same spectral range [5] and the operating wavelength range (up to 2.8 m) is ~0.5 m longer compared to state of the art hybrid LMs colloidal quantum dots PDs [6,7]
Stability of topic modeling via matrix factorization
Venue: Expert Syst. Appl.
Year: 2018

The problem of the instability of standard topic modeling algorithms is investigated.Three new stability measures for topic models are proposed.Two new ensemble approaches for topic modeling with matrix factorization are proposed.A detailed evaluation of these approaches is performed on 10 text corpora. Topic models can provide us with an insight into the underlying latent structure of a large corpus of documents. A range of methods have been proposed in the literature, including probabilistic topic models and techniques based on matrix factorization. However, in both cases, standard implementations rely on stochastic elements in their initialization phase, which can potentially lead to different results being generated on the same corpus when using the same parameter values. This corresponds to the concept of instability which has previously been studied in the context of k means clustering. In many applications of topic modeling, this problem of instability is not considered and topic models are treated as being definitive, even though the results may change considerably if the initialization process is altered. In this paper we demonstrate the inherent instability of popular topic modeling approaches, using a number of new measures to assess stability. To address this issue in the context of matrix factorization for topic modeling, we propose the use of ensemble learning strategies. Based on experiments performed on annotated text corpora, we show that a K Fold ensemble strategy, combining both ensembles and structured initialization, can significantly reduce instability, while simultaneously yielding more accurate topic models.
Chronic Granulomatous Disease: a Comprehensive Review
Venue: Clinical Reviews in Allergy Immunology
Year: 2020

Chronic granulomatous disease (CGD) is a primary immunodeficiency of phagocyte function due to defective NADPH oxidase (phox) Compared with the common types of CYBB/ gp91 phox NCF1 /p47 phox and CYBA /p22 phox deficiency, NCF4 /p40 phox deficiency is a mild and atypical form of CGD without invasive bacterial or fungal infections. It can be diagnosed using serum opsonized E.coli as a stimulus in dihydrorhodamine (DHR) assay. Patients with CYBC1 /Eros deficiency, a new and rare form of CGD, present as loss of respiratory burst and gp91 phox expression in phagocytes. Neutrophils from patients with CGD are deficient in neutrophil extracellular traps (NETosis) autophagy, and apoptosis. The hyper activation of NF kB and inflammasome in CGD phagocytes also lead to long lasting production of pro inflammatory cytokines and inflammatory manifestations, such as granuloma formation and inflammatory bowel disease like colitis. Patients with CGD and X linked female carriers also have a higher incidence of autoimmune diseases. The implementation of antimicrobial, anti fungal, and interferon g prophylaxis has greatly improved overall survival. Residual NADPH oxidase activity is significantly associated with disease severity and the chance of survival of the patient. New therapeutic approaches using immunomodulators for CGD related inflammatory manifestations are under investigation, including pioglitazone, tamoxifen, and rapamycin. Hematopoietic stem cell transplantation (HSCT) is the curative treatment. Outcomes of HSCT have improved substantially over the last decade with overall survival more than 84 90% but there are debates about designing optimal conditioning protocols using myeloablative or reduced intensity regimens. The gene therapy for X linked CGD using hematopoietic stem and progenitor cells transduced ex vivo by lentiviral vector encoding the human gp91phox gene demonstrated persistence of adequate oxidase positive neutrophils in a small number of patients. Gene therapy using genome editing technology such as CRISPR/Cas9 nucleases is a promising approach for patients with CGD in the future.
Probiotic microorganisms and antiviral plants reduce mortality and prevalence of WSSV in shrimp (Litopenaeus vannamei) cultured under laboratory conditions
Year: 2012

The protective e!ect of a probiotic mixture (PM) and antiviral plants, against the white spot sindrome virus (WSSV) in Litopenaeus vannamei, was evaluated in three experiments. The PM was composed of four lactic acid bacteria (LAB) and one yeast strain. The plant mixture was composed of Ocimum sanctum and commercial antiviral plants (VPHs, HSVs) Shrimp in each experiment (weighing 2.7 0.7, 11.5 1.3, 11.70 2.5 g) were cultured in120 L plastic tanks and fed twice a day with commercial feed plus additives (plants or bacteria and yeast) Animals were monitored for the occurrence of WSSV by singlestep and nested PCR. The PMand powdered antiviral plants added to the commercial feed showed an increase in survival and a decrease in the prevalence of WSSV in shrimp. The results showed that both the PM and the powdered antiviral plants can provide protection for shrimp againstWSSV.
A multiscale cerebral neurochemical connectome of the rat brain
Venue: PLoS biology
Year: 2017

Understanding the rat neurochemical connectome is fundamental for exploring neuronal information processing. By using advanced data mining, supervised machine learning, and network analysis, this study integrates over 5 decades of neuroanatomical investigations into a multiscale, multilayer neurochemical connectome of the rat brain. This neurochemical connectivity database (ChemNetDB) is supported by comprehensive systematically determined receptor distribution maps. The rat connectome has an onion type structural organization and shares a number of structural features with mesoscale connectomes of mouse and macaque. Furthermore, we demonstrate that extremal values of graph theoretical measures (e.g. degree and betweenness) are associated with evolutionary conserved deep brain structures such as amygdala, bed nucleus of the stria terminalis, dorsal raphe, and lateral hypothalamus, which regulate primitive, yet fundamental functions, such as circadian rhythms, reward, aggression, anxiety, and fear. The ChemNetDB is a freely available resource for systems analysis of motor, sensory, emotional, and cognitive information processing.
Towards Visual SLAM with Event based Cameras
Year: 2015

Event based cameras  offer much potential to the fields of robotics and computer vision, in part due to their large dynamic range and extremely high "frame rates" These attributes make them, at least in theory, particularly suitable for enabling tasks like navigation and mapping on high speed agile robotic platforms under challenging lighting conditions, a task which has been particularly challenging for traditional algorithms and camera sensors. Before these tasks become feasible however, progress must be made towards adapting and innovating current RGB camera based algorithms to work with event based cameras. In this paper we present ongoing work towards this goal and an initial milestone the development of a constrained visual SLAM system that can create semi metric, topologically correct maps of a 2.7 km traverse through a large environment at real time speed  Although much more sophistication is yet to be built into the system, we hope this work serves as a baseline for future research using these novel sensors.
Curriculum Learning for Domain Adaptation in Neural Machine Translation
Venue: NAACL
Year: 2019

We introduce a curriculum learning approach to adapt generic neural machine translation models to a specific domain. Samples are grouped by their similarities to the domain of interest and each group is fed to the training algorithm with a particular schedule. This approach is simple to implement on top of any neural framework or architecture, and consistently outperforms both unadapted and adapted baselines in experiments with two distinct domains and two language pairs.
Adult Attachment Style, Emotion Regulation, and Social Networking Sites Addiction
Venue: Front. Psychol.
Year: 2019

While there is substantial evidence that emotion regulation plays a role in the maintenance of substance and behavior addiction, its role in addiction to social networking sites (SNS) remains unclear. Drawing on attachment theory, we explore whether emotion regulation mediates the relationship between insecure attachment and SNS addiction among 463 college students. The participants completed the short version of the Experience in Close Relationships Scale, Difficulties in Emotion Regulation Scale, and Chinese Social Media Addiction Scale. The results indicated that attachment anxiety positively predicted SNS addiction and that emotion regulation mediated this link. These findings suggest that individuals' affective regulation capability should be a target of future interventions and treatments.
HCI in food product innovation
Venue: CHI Extended Abstracts
Year: 2014

Food is essential to the survival of the world population. There are several processes in order to make food available to consumers: for example, production, transportation, and consumption. Since the global demand of food is always on the rise, there is a need to improve the efficiency in all the processes in food industries. For example, the food production industries are often not equipped with the right decision making tools to allow farmers to properly deal with important factors such as environmental changes. On the other hand, tools are not difficult to create but can be very challenging to be successfully adopted by the professionals, especially when the tools require them to change their normal work practices. In this SIG, we will discuss how HCI can improve food product industries with suitable information for each food process.
Coordination of dual function acquisition price and corporate social responsibility in a sustainable closed loop supply chain
Year: 2020

In reverse supply chains, acquisition price strategy provided by manufacturers plays an essential role in collecting used products. On the other hand, owing to the fact that the acquisition price contributes to the improvement of the environmental sustainability, it can influence the purchasing behaviors of eco friendly customers. Thus, acquisition price strategy not only can positively affect the amount of returned products but also can positively affect the market demand. This study integrates bilateral effects of the acquisition price to analyze the performance of a sustainable closed loop supply chain (CLSC) by introducing a dual function acquisition price. This paper also contributes to the sustainable CLSC literature by proposing an analytical coordination mechanism to coordinate the dual function acquisition price as an environmental sustainability and corporate social responsibility (CSR) as a social sustainability. Motivated by a real case of dairy industry, the bilateral effects of the acquisition price on both reverse and forward channels are considered through its dual functionality. In the sustainable CLSC consisting of two competitive manufacturers and one retailer, the manufacturers compete with each other on the dual function acquisition price offered to the customers. Moreover, to facilitate the collection process, the manufacturers encourage the retailer to do the collection process by offering him a credit time scheme. Besides the collection process, the retailer invests in the CSR as social sustainability to boost the market share. At first, we use a manufacturer Stackelberg game to model the problem under decentralized structure where each member individually optimizes its own profitability. Afterward, the problem is formulated under centralized structure where the decision variables are determined from CLSC viewpoint. Then, a compensation based wholesale price contract is developed to coordinate the competitive CLSC under coordinated model. Using the data of the case study, the results demonstrate that the proposed contract enhances the whole CLSC and all members' profitability, the manufacturers' dual function acquisition price, and the retailer's CSR investment. Therefore, the developed contract can improve the performance of the competitive CLSC from environmental, social, and economic viewpoints.

Year: 2020

The purpose of the study was to investigate the impact of integrating flipped learning and information and communication technology on secondary school students' academic achievement and attitudes. The study was based on a quasi experimental approach where the sample of the study consisted of 40 students from Mashrek International School in Amman, Jordan, who were randomly assigned into either an experimental group (20 students) or control group (20 students) An academic achievement test was used with both groups as a pre test and post test, and an attitude scale was implemented only on the experimental group. The validity and reliability of the study were ensured. The findings revealed the effectiveness of the flipped learning approach, statically significant differences were found between the experimental and control group in terms of the students' academic achievement. As for the experimental group the students' attitudes towards peers, teacher, environment and learning process were positive.

Exogenous Secretin Improves Parenteral Nutrition Associated Liver Disease in Rats.
Venue: Journal of pediatric gastroenterology and nutrition
Year: 2020

Intestinal failure associated liver disease (IFALD) is a feared and life threatening complication in neonates with intestinal failure (IF) receiving long term total parenteral nutrition (TPN) This study aims to investigate the effect of exogenous secretin on liver pathology and hepatic function in a rat model of parenteral nutrition associated liver disease (PNALD) METHODS Male Sprague Dawley rats underwent right jugular venous catheterization to receive 14 day continuous TPN therapy. All rats were allocated into 3 groups: (1) the Control group (n 8) did not have surgery or TPN and was fed standard rat chow ad libitum; (2) the TPN group (n 8) underwent catheter insertion and TPN treatment; and (3) the TPN/S group (n 8) also underwent catheter insertion, TPN treatment and exogenous secretin treatment (2.5 nmol/kg/d) daily. Fourteen days after initial surgery, we collected the animals' liver and blood samples for further test.  The TPN/S group had diminished direct bilirubin (TPN, 2.1 0.7 mmol/L; TPN/S, 1.5 0.2 mmol/L) and liver total bile acid levels (TPN, 144.5 21.2 mmol/L; TPN/S, 123.4 10.4 mmol/L) and improved histological outcomes compared with those in the TPN group. Exogenous secretin also enhanced the canalicular transporter (BSEP, 0.5 fold, P 0.011) and inhibited the basolateral transporter (OSTA, 0.48 fold, P 0.002; OSTB, 0.6 fold, P 0.013) of liver bile acid.  In this animal model of PNALD, secretin may improve cholestasis by enhancing canalicular transport, inhibiting the basolateral export of liver bile acid, and eventually decreasing the total bile acid level in the liver. Exogenous secretin treatment may potentially prevent and treat IFALD in IF patients relying on long term TPN therapy.
An Evaluation of the Study Habits and Learning Strategies of Students in an Irish Medical School and their Correlation with Academic Success
Year: 2013

Recent studies have shown that a combination of personality factors, aptitude and study habits/strategies are strong determinants of academic success at medical school. In particular, there is limited evidence to suggest that study skills such as efficient time management and self testing are associated with better overall exam performance.  To determine the successful and detrimental study habits and learning strategies of UCC medical students.  A newly devised questionnaire instrument investigating study habits (including use of social media during study) as well as the Approaches and Study Skills Inventory for Students (ASSIST; Tait et al. 1998) were distributed to Year 2 and final year UCC medical students. Year score percentage from the preceding year was the measure of academic achievement.  A significant difference in year score percentage was found between students who study consistently (M=66.33% SD=7.84% and those who rely on lastminute study sessions "cramming" (M=66.33% SD=8.14% p 0.0001) as well as between students who used social networking sites often during study time (M=67.24% SD=9.18) vs. those who refrain from use during study (M=72.88% SD=9.11; p 0.02) Year score percentage was positively correlated with effort management/organised studying strategy (rs[176] 0.39, p 0.01) conversely, a negative correlation was found between year score percentage and surface learning strategy (rs[177] 0.34, p 0.01) CONCLUSION These data indicate that effort management and organised studying should be promoted, and surface rote learning discouraged, as part of any effort to encourage development of study skills at medical school.
