Previsión Colaborativa: una introducción al Estado del Arte

Este articulo realiza una revision de las aportaciones realizadas por diferentes autores al concepto de Prevision Colaborativa. El intercambio de informacion y la colaboracion en la gestion de la produccion entre integrantes de una cadena de suministro puede aplicarse a diferentes areas de gestion. Sin embargo, se ha dedicado un mayor esfuerzo para la defi nicion de modelos, metodologias y herramientas a areas como planifi cacion y aprovisionamiento que a la de prevision de demanda. Para el analisis de las aportaciones al ambito de la Prevision Colaborativa se han defi nido trece dimensiones genericas, aplicables al analisis de cualquier otro proceso colaborativo. Se concluye que la mayoria de los autores se centran en la descripcion de las ventajas de la Prevision Colaborativa y la relacionan con otros procesos colaborativos (como CPFR), sin embargo, escasean las aportaciones mas relacionadas con las herramientas a utilizar o los metodos para llevar a la practica el proceso colaborativo.
Non-alcoholic fatty liver disease: An under-recognized cause with emerging importance

Non-alcoholic fatty liver disease (NAFLD) and its more aggressive form, non-alcoholic steatohepatitis (NASH) are entities that are becoming more and more interesting to the medical community in general. The increased prevalence of diabetes, obesity, hypertension and hypertriglyceridemia are considered to be important causes for NAFLD. The prognosis of simple NAFLD is generally benign. But fibrosis, ballooning of the hepatocytes, inflammation and Mallory bodies are indicators of progression to cirrhosis. Although liver biopsy is currently the gold standard for diagnosis, there is a need for developing less invasive methods, and hence there is no effective medical therapy available for NAFLD. A better understanding of the pathogenesis and natural history of NASH will help identify the subset of patients at risk of progressing to advanced liver disease.
Comparing Contemporaneous Laboratory and Field Experiments on Media Effects

Experimenters often conduct their studies in the laboratory or in the field. Each mode has specific advantages (e.g., the control of the lab versus the realistic atmosphere of the field). We develop two hypotheses concerning the relationship between treatment effects in lab and field settings that are tested in contemporaneous experiments. In particular, registered voters in a medium-sized city were assigned to a laboratory or a field experiment involving newspaper treatments. The analyses show significantly larger treatment effects in the laboratory experiment, especially for public opinion outcomes in which the content of the treatment could be readily linked to the dependent variable. There also is suggestive evidence that as lab and field experiments become similar on one particular dimension (the temporal distance between stimulus and outcome), differences in the size of treatment effects moderate.
A Real Time Animal Detection And Segmentation Algorithm For IRT Images In Indoor Environments

The segmentation of objects of interest in an image is one of the first processing steps in numerous applications of image processing. A variety of algorithms and applications of segmentation are described in the literature, but very few have been applied to thermal infrared images, and even less in the context of livestock farming. Most of the literature approaches use either approaches based on optimisation algorithms which cannot be used for real time applications, or linear thresholds which often induce the presence of many artifacts in the resulting image. In this paper we propose a new algorithm to achieve the segmentation of animals in indoor environment images.

Reporting Minority Students' Test Scores: How Well Can the NAEP Account for Differences in Social Context?.

This paper investigates the adequacy of the National Assessment of Educational Progress (NAEP) for taking into account dissimilarities in students' family, school, and community contexts when reporting test score differences among population groups (i.e., racial and ethnic minorities). This question was addressed by comparing the NAEP to other representative data for grades 8 and 12 from the National Education Longitudinal Survey (NELS) and High School and Beyond (HSB), studies that contain richer social context measures. These analyses show that the NAEP lacks a number of important social context measures and that the equality of some (but by no means all) of NAEP's measures is low because of reliance on student self-reports and other unreliable data sources. These weaknesses of the NAEP have important practical implications. Compared to HSB and NELS, the NAEP usually overestimates the achievement differences between students who come from different population groups but similar social contexts. However, at the secondary school level at which these analyses were conducted, these overestimates reflect primarily the NAEP's lack of important measures rather than its reliance on student self-reports.

Research Paper: Concept Analysis of OccupaƟ onal Therapy Handling in the Children with Cerebral Palsy: A Hybrid Model

ObjecƟ ve The purpose of the present study was to analyze the concept of occupaƟ onal therapy handling in the children with cerebral palsy from the perspecƟ ve of occupaƟ onal therapy instructors and clinicians in Iran. Materials and Methods In this qualitaƟ ve study, the hybrid model was used in three phases to analyze the concept of handling in the children with cerebral palsy. In the theoreƟ cal phase, we conducted a review of relevant arƟ cles published unƟ l the year 2014 in authenƟ c databases. In the fieldwork phase, the sampling was done randomly through deep and semi-structured interviews with six clinical therapists and meeƟ ng with the presence of 11 therapists and two observaƟ ons in clinic. Then, the results were written and the content was analyzed. In the final phase, the two previous phases were generally analyzed. Results The results were classified in five main categories as: (1) care of child, (2) management of treatment, (3) manual techniques, (4) educaƟ on of acƟ viƟ es of daily living (ADL), and (5) liŌ ing and carrying. According to the parƟ cipants, core aƩ ributes of handling include “control, safety, transfer and posiƟ oning”. Conclusion It seems that the results of this study may help in clarifying the concept of occupaƟ onal therapy handling in children with CP. In addiƟ on, by idenƟ fying the process, barriers and facilitaƟ ve factors, and the concept of handling, occupaƟ onal therapy instructors and therapists will be able to design and run their educaƟ onal acƟ viƟ es based on scienƟfic findings which can provide them with the necessary condiƟ ons for educaƟ on, learning and proper execuƟ on of handling in occupaƟ onal therapy.

N-terminal pro brain natriuretic peptide are enhanced in people with the uncomplicated metabolic syndrome: a nested case-control analysis of the population-based Casale Monferrato

Background: Both metabolic syndrome (MetS) and NT-proBNP confer increased risk of cardiovascular diseases (CVD). We assessed if NT-proBNP levels were greater in people with uncomplicated MetS, who had neither CVD/chronic kidney disease (CKD) nor diabetes, as compared to subjects who met none of the defining criteria of the MetS. Methods: A case-cohort study from the non-diabetic population-based Casale Monferrato Study was performed, after exclusion of all subjects with established CVD, CKD (eGFR<60 ml/min/1.73m 2 ) and CRP values ≥ 3 mg/l. Cases (n=161) with MetS were compared to all subjects within the cohort (n=124) who were completely free of any component of the MetS. Serum NTproBNP were centrally measured by immunoenzymatic assay. Results: NT-proBNP levels were significantly higher in cases than in control subjects [35.4 (15.598.2) vs 24.4 (11.7-49.6) pg/ml, p=0.014]. In logistic regression analysis, compared to NT-proBNP values in the lower quartiles (≤49.64 pg/ml), higher values conferred OR 4.17 (1.30-13.44) of having the MetS, independently of age, sex, microalbuminuria, CRP, eGFR, and central obesity. This association was evident even after the exclusion of hypertensive subjects. Further adjustment for log-HOMA and diastolic blood pressure did not modify the strength of the association, while central obesity was a negative confounder. Conclusions: Compared to people without any component of the MetS, those with uncomplicated MetS, who had neither CVD/CKD nor diabetes, had increased NT-proBNP values, even if they were normotensive and though absolute values were still in the low range. The insulin-resistance state did not mediate this association, while central obesity was a negative confounder.
Will information-communications systems survive? Web 2.x and SocNet as placebos or real internet survival kit

Since the information-communications systems lay on three interactive portions of infrastructure (network, information bases, devices/interfaces), t he current Internet domination of Web 2.x will be finished very soon. The Internet as we are using today has to be changed. In particular, the next generation of Internet has to be more user fri endly, information oriented and computerless interfaced. It should add features that will help u sers utilize it in the same way they utilize other methods of communication and transport and have the same or superior level of flexibility. What will be with Internet if it would not answer on new demand for greater and more flexible/mobile communication? Some projections are based on presumptions that Internet will not survive. In contrary, there are also presumptions that Internet could survive with Web 2.x and Social Networks development and with IPv6 as well. Does it means real base and solution for helping Internet to stay alive or it is only placebo for today's Internet users. In order to reshape current Intern et status, some Web 2.x and Social Networks deployments are described in this paper as well as the assumptions on the structure of survival kit for In ternet to stay alive in the future.
Image Analysis of Leafy Spurge (Euphorbia esula) Cover

We examined whether image analysis could separate leafy spurge from other plant species and objects by comparing image analysis to the ocular method of estimating cover. Image analysis was acceptably precise at low and medium cover levels. Image analysis was as repeatable as the ocular method at all sites and cover levels and acceptably reliable at low and medium cover levels but estimated cover lower by 12 to 22% than the ocular method at high cover levels. The average error levels of image analysis and the ocular method did not differ. Estimating leafy spurge cover with a 10% error required only 20 quadrats when image analysis was used, while twice as many quadrats were needed when cover was measured ocularly. Image analysis was recommended as a measurement tool because quantification was efficient, the equipment is inexpensive, and the color prints provide a permanent photo record of the study.
Non-invasive measuring method of skin temperature based on skin sensitivity index and deep learning

In human-centered intelligent building, real-time measurements of human thermal comfort play critical roles and supply feedback control signals for building heating, ventilation, and air conditioning (HVAC) systems. Due to the challenges of intra- and inter-individual differences and skin subtleness variations, there is no satisfactory solution for thermal comfort measurements until now. In this paper, a non-invasive measuring method based on skin sensitivity index and deep learning (NISDL) was proposed to measure real-time skin temperature. A new evaluating index, named skin sensitivity index (SSI), was defined to overcome individual differences and skin subtleness variations. To illustrate the effectiveness of SSI proposed, two multi-layers deep learning framework (NISDL method I and II) was designed and the DenseNet201 was used for extracting features from skin images. The partly personal saturation temperature (NIPST) algorithm was use for algorithm comparisons. Another deep learning algorithm without SSI (DL) was also generated for algorithm comparisons. Finally, a total of 1.44 million image data was used for algorithm validation. The results show that 55.6180% and 52.2472% error values (NISDL method I, II) are scattered at [0, 0.25), and the same error intervals distribution of NIPST is 35.3933%.

ABSTRACT The real time determination of the critical states of operation of the fuel cell proton exchange membrane (acronym in English, PEM) is one of the main challenges for the control systems of PEM fuel cells. In this paper, the development and implementation of a non-invasive low cost method based on fuzzy decision techniques to estimate the critical states of operation of the PEM fuel cell is presented. The estimation is performed by perturbations of the state of operation of PEM fuel cell and the subsequent analysis of the temporal evolution of the voltage generated by the cell. The implementation of this stimulation-perceived technique of the state of fuel cell for the detection of critical states is a novelty and a step towards autonomous control in optimal operation of PEM fuel cells. Keywords: PEMFC characterization, membrane flooding and dehydratation state, fuzzy decision tree, control, fuzzy logic.
The development trends of the main drivers for attracting students into the tertiary education sector in Latvia – distance learning and internationalization

The European Union (EC-JRC, 2010), has stressed that higher education must change and adapt to economic and social needs, that institutional change is essential to educational innovation, and that information and communication technologies (ICT) must form part of the teaching and learning process. The second international challenge is to encourage international cooperation between institutions in order to share knowledge across borders and facilitate collaboration (Morin, 2009) and post-cosmopolitan citizenship (Dobson and Bell, 2006). The dramatic decrease of the number of students in Latvia in the last 10 years by 64% and disproportionally high number of HE institutions, makes Latvia’s Government, the Ministry of Education and Science and higher education institutions to look for new ways to structure and optimize the processes in the higher education sector. The main research question of this paper is: the general development trends of the main drivers for attracting more students into the tertiary education sector in Latvia by means of online education and internationalization. The relevance of the research: the authors review the intersections of the distance learning and internationalization as the optimal solutions for the critical situation in the Latvian higher education sector with lack of students.
Rubber band recoil

When an initially stretched rubber band is suddenly released at one end, an axial-stress front propagating at the celerity of sound separates a free and a stretched domain of the elastic material. As soon as it reaches the clamped end, the front rebounds and a compression front propagates backward. When the length of the compressed area exceeds Euler critical length, a dynamic buckling instability develops. The rebound is analysed using Saint-Venant's theory of impacts and we use a dynamical extension of the Euler–Bernoulli beam equation to obtain a relation between the buckled wavelength, the initial stretching and the rubber band thickness. The influence of an external fluid medium is also considered: owing to added mass and viscosity, the instability growth rate decreases. With a high viscosity, the axial-stress front spreads owing to viscous frictional forces during the release phase. As a result, the selected wavelength increases significantly.
In-vitro establishment, germination and growth performance of Babel Acacia (Acacia jacquemontii Benth)

The main objectives of the present study were to determine the growth behavior, germination percentage in petri dishes at different time duration and different field soil mediums, collected from the depths of 0-0.5 m, 0.5-1.0 m and above >1.0 m at different time periods during the growing seasons of 2013 to 2014. Ripened pods of Acacia species were collected from the field and seeds were isolated from pods. Then such seeds were stored in sealed paper bags for one a week and were dried under normal room temperature. Growth parameters of the twigs were measured after every 15 days. In nursery conditions, seeds soaked with cold/hot water had higher germination (82-94%) in petri dishes than the non-soaked seeds of the species. Seeds sown in pots had 51-70% germination. Seedlings of the species had higher fresh/dry weights of their shoots than the roots. In contrast, the roots of the Acacia seedlings elongated at a higher rate than the shoots.

STUDY OF QUALITY STANDARDS APPLICATION IN BUCHAREST COMMUNITY PHARMACIES

The concept of quality standard is a modern notion, frequently used in specialty literature [1, 2, 3] to identify reference points, minimum requirements that need to be respected by the pharmacist, the supplier of pharmaceutical services. The presentation of the method of implementing quality standards in the pharmaceutical activity, performed in this paper, has followed a quantitative (of the number of pharmacies) and qualitative (of the evaluation criterias) exposure. The introduction of these regulations in pharmacies was evaluated by special evaluation teams and it has been ascertained that, in general, the implementation of the quality management system was initiated and is under development. The research undertaken has demonstrated that the quality concept application in the evaluated pharmacies in Bucharest represents an important step that endorses the ensurance of organisational competitiveness, the modeling of practices dependent on the actual tendencies, in an effective and efficient manner. Rezumat Conceptul standard de calitate este o noţiune modernă, frecvent folosită in literatura de specialitate [1, 2, 3] pentru a identifica puncte de referinţă, cerinţe minime, care trebuie respectate de către farmacist, furnizorul de servicii farmaceutice. Prezentarea modului de implementare a standardelor de calitate in activitatea farmaceutică, realizată in această lucrare, a urmărit o expunere cantitativă (a numărului de farmacii) si calitativă (a criteriilor de evaluare). Introducerea acestor norme in farmacii a fost evaluată de echipe specializate in acest domeniu si s-a constatat că, in general, sistemul de management al calităţii a inceput să fie implementat. Demersul intreprins a demonstrat că aplicarea conceptului calităţii in farmaciile evaluate din Bucuresti reprezintă un pas important care vizează asigurarea competitivităţii organizaţionale, modelarea practicilor dependent de tendinţele actuale, eficace si eficient.
Evolutionary Theory and Political Behavior

Political behavior is behavior aimed at regulating access to resources: Who is recognized to get what, when, and how? Evidence across a number of disciplines shows that humans over evolutionary history have evolved sophisticated abilities to engage in political behavior through status seeking and coalition formation in order to attract resources to themselves, their kin, and their allies. As demonstrated by recent research, this evolutionary history of politics continues to shape how modern individuals behave in modern mass politics and prompt people to derive their political attitudes from ancestrally relevant factors such as upper body strength and short-term fluctuations in hunger. Important areas for research lies ahead in (i) understanding how evolution has given rise to individual variation in political behavior, (ii) investigating the extent to which the evolved psychology of humans biases modern political behavior, and (iii) strengthening the ties between this emerging application of evolutionary theory and more traditional research on political behavior. Keywords: evolutionary theory; evolution; political behavior; resources; modern individuals; political attitudes; research; individual variation; human biases
Tuning Hadoop map slot value using CPU and IO metrics

Hadoop is a widely used open source mapreduce framework. Its performance is critical because it increases the usefulness of products and services for a large number of companies who have adopted Hadoop for their business purposes. One of the configuration parameters that influences the resource allocation and thus the performance of a Hadoop application is map slot value (MSV). MSV determines the number of map tasks that run concurrently on a node. For a given architecture, a Hadoop application has an MSV for which its performance is best. Furthermore, there is not a single map slot value that is best for all applications. A Hadoop application’s performance suffers when MSV is not the best. Therefore, knowing the best MSV is important for an application. In this work, we find a low-overhead method to predict the best MSV using two new Hadoop counters that measure per-map task CPU utilization and IO throughput. Our experiments on a wide variety of Hadoop applications show that using the best MSV for each application improves the aggregate performance by 5% up to 132% when compared to using a single MSV for all applications.
