Mujeres en la popularización del software libre en Colombia: reflexiones situadas en torno al género y la tecnociencia
Authors: Pérez Bustos Tania
Published: May 2019

El presente ensayo aborda la pregunta por el género como configurador de la subjetividad en el territorio de la producción de conocimiento tecnológico y hace énfasis en las dinámicas constituyentes de la comunidad de software libre en Colombia. Inscribe esta reflexión local, por un lado, en las discusiones sobre el género como categoría analítica en general, y sobre el género y la ciencia y la tecnología en particular. Por otro, se centra en reflexionar sobre las experiencias de vida de algunas de las mujeres que conforman este colectivo y en comprender cómo su papel, aunque minoritario, aporta en la apuesta política del movimiento de software libre por democratizar el conocimiento tecnológico. Esta reflexión es puesta en diálogo con aquellas que sobre el particular se han hecho a escala global.

Es indudable que el problema de la subjetividad se convirtió en un asunto fundamental para comprender los complicados mecanismos que mueven la modernidad. En nuestra época, las complejidades de la educación, la cultura y la política, entre otros factores de la sociedad, son difíciles de estudiar y comprender aislados de la subjetividad. Tal vez a ello se deba que actualmente buena parte de los estudios educativos y pedagógicos atienden la dimensión subjetiva buscando elementos para la comprensión de los conflictos en los procesos de las transformaciones culturales y políticas de nuestro tiempo.Respondiendo a esta preocupación, con la presente edición, estamos ofreciendo a los lectores Pedagogía y Saberes, interesados y preocupados por los problemas educativos y pedagógicos, un bloque temático de artículos relacionados con la subjetividad.
La profesión docente, sus múltiples funciones y campos de acción: aproximación a la resignificación pedagógica
Authors: Saavedra Rey Liliana
Published: May 2019

Las transformaciones sociales de la actualidad y su consecuente diversificación de los campos de acción y funciones del profesorado han generado el estado de malestar docente caracterizado por la insatisfacción de los maestros debido a la multiplicidad de sus responsabilidades y sus desfavorables condiciones socio-laborales. Frente a este contexto, esta reflexión enfatiza en la resignificación de las funciones del maestro desde la pedagogía, atendiendo a su propósito educativo. En este sentido, se analizan los campos de acción y la caracterización de la función docente en la normatividad educativa y en la praxis social, definiendo sus alcances y límites más allá de las políticas de mercado que los condicionan, como una propuesta pedagógica centrada en la formación de seres humanos integrales y su sociedad. Este articulo hace parte de la investigación "Sentido de la evaluación docente a partir de la definición de la complejidad de las funciones del profesorado. Una aproximación a la resignificación pedagógica” presentada por la autora como tesis de grado en la Maestría de Educación de la Universidad Pedagógica Nacional, a la cual se le otorgó la distinción de tesis meritoria.

Authors: Pereira Tatielle Andrade , Bezerra Natália Maria Barbosa , Fonseca Filho Gentil Gomes , Lemos Leal Luana Cecilia Farache , Lisboa Lilian Lira
Published: May 2019

INTRODUÇÃO: O tratamento da Bexiga Neurogênica (BN) pode ser feito através do manejo farmacológico e/ou não farmacológico. Dentro do tratamento não farmacológico temos a neuromodulação não invasiva (NMNI) realizada com aplicação de eletrodos transcutâneos que sugere uma modulação nos componentes excitatórios e inibitórios do controle da bexiga. OBJETIVO: Reunir evidencias que avaliem o efeito da NMNI na BN de crianças com disfunções neurológicas. MÉTODOS: Trata-se de um artigo de revisão integrativa que foi elaborada seguindo sete etapas. A busca foi feita nas bases de dados PubMed, Biblioteca Virtual de Saúde (BVS) e ScienceDirect. A escolha dos artigos foi realizada inicialmente por dois avaliadores independentes, obedecendo os critérios de elegibilidade: realizar tratamento para BN utilizando estimulação elétrica não invasiva com objetivo de neuromodulação da via urinária; população amostral composta por crianças com alteração miccional em decorrência de alguma disfunção neurológica e possuir os textos disponíveis na íntegra nas plataformas online de busca, no período de Agosto a Novembro de 2018. Foram incluídos artigos que utilizaram NMNI como tratamento da BN em crianças. RESULTADOS: Foram encontrados 440 artigos e apenas 5 atenderam aos critérios de inclusão. Ao todo, participaram dos estudos 141 crianças com acometimentos neurológicos. Os principais elementos utilizados nas avaliações foram diário miccional, o estudo urodinâmico, a coleta da história clínica e o exame físico. Os parâmetros de estimulação e posicionamento de eletrodos foram variados. CONCLUSÃO: A NMNI apresentou bons resultados no tratamento de crianças com BN e, foi observado também, efeitos positivos no intestino neurogênico, porém, são necessários mais estudos que sugiram protocolos bem delineados para a reprodução na prática clínica.

gmcSCRB-seq protocol v2
Authors: JWB Bagnoli Johannes , Ziegenhain Christoph , Janjic Aleksandar , Esteban Wange Lucas , Vieth Beate , Parekh Swati , Geuder Johanna , Hellmann Ines , Enard Wolfgang
Published: May 2019

gmcSCRB-seq is an alternative lysis protocol to mcSCRB-seq (Publication and Protocol). gmcSCRB-seq uses Guanidine Hydrochloride in the lysis buffer and requires an additional cean up step. We recommend using this alternative lysis protocol in cases where cells are difficult to lyse or where the DNA appears degraded following the pre-amplification step. However, we have observed reduced sensitivity with gmcSCRB-seq compared to mcSCRB-seq and would therefore only recommend using it in cases where the latter does not produce high quality libraries.

UC Davis - Glugagon v1
Authors: Havel Peter
Published: May 2019

Summary: Glucagon is a 29 amino acid polypeptide processed from proglucagon in pancreatic alpha cells. In intestinal L-cells proglucagon is cleaved into glicentin, corresponding to proglucagon residues no 1-69. Glicentin can further be processed into oxyntomodulin, corresponding to proglucagon residues no 33-69. These peptides are released simultaneously upon stimulation. Moreover, a fragment of glucagon corresponding to its Cterminal part (residues no 19-29), also designated mini-glucagon, is reported to be present in the pancreas in low amounts compared to the total glucagon content. In general, glucagon has an effect opposite that of insulin, i.e. it raises blood glucose levels. It causes the liver to convert glycogen into glucose, which is then released into the blood stream. With longer stimulation, glucagon action in the liver results in a glucose-sparing activation of free fatty acid oxidation and production of ketones. During hypoglycaemia, glucagon secretion offers a protective feedback mechanism, defending the organism against damaging effects of glucose deficiency in the brain and nerves.

UC Davis - Non-Esterified Fatty Acids Protocol v1
Authors: Havel Peter
Published: May 2019

Summary: The Wako enzymatic method relies upon the acylation of coenzyme A (CoA) by the fatty acids in the presence of added acyl-CoA synthetase (ACS). The acyl-CoA thus produced is oxidized by added acyl- CoA oxidase (ACOD) with generation of hydrogen peroxide, in the presence of peroxidase (POD) permits the oxidative condensation of 3-methy-N-ethyl-N(β-hydroxyethyl)-aniline (MEFA) with 4-aminoantipyrine to form a purple colored adduct which can be measured colorimetrically at 550 nm.
UC Davis - RadioImmuno Assay (RIA) Protocol v1
Authors: Havel Peter
Published: May 2019

Summary: The RIA (RadioImmuno Assay) is an assay method used for the quantification of various proteins. A standardized concentration of antibody specific to the analyte of interest is pipetted into test tubes. A standardized concentration of the analyte of interest that is labeled with a radioisotope (usually 125I) is added to the tubes. Standards and samples are pipetted into the tubes and the tubes are incubated. During the incubation period the standardized concentration of labeled analyte and the unknown concentration of analyte in the samples will compete for binding sites on the antibody. After the incubation period a precipitating reagent is added to the tubes and the bound antibodies are precipitated out using the double antibody-polyethyleneglycol precipitation technique. The tubes are centrifuged and the supernatant is aspirated and the precipitate is counted (using a gamma counter if 125I is used). If there is a low concentration of the analyte of interest in the samples, the labeled analyte will have a higher probability for binding to the antibody and thus there will be a higher count in the precipitate. If there is a high concentration of the analyte of interest in the samples there will be a lower count of labeled analyte in the precipitate. The counts and known concentrations of the standards are used to generate a standard curve, and the counts of the samples are used to interpolate quantitative concentrations for the analyte of interest from the standard curve.

Authors: YU Hui , ZHANG Panpan , WANG Xiao , WANG Yan , ZHANG Binyu
Published: May 2019

Background: We aimed to explore the effect of health education and nursing intervention model based on behavioral change theories on self-efficacy and self-management behaviors in patients with chronic heart failure.
Methods: Eighty-six patients with chronic heart failure treated in the First Hospital Affiliated to Harbin Medical University (Harbin, China) from November 2016 to January 2018 were enrolled in this study. The patients were evenly divided into control group and observation group (43 patients in each group), according to the random number table method. Patients in the control group received a routine health education intervention. Patients in the observation group received health education based on behavioral change theories in addition to the routine nursing intervention. The health education included mastering of the disease-related theoretical knowledge, daily self-management and exercising guidance. After 8 weeks of intervention, the self-efficacy level, self-management ability and quality of life were assessed and compared between the two groups.
Results: The self-management behavior score in the observation group was higher than those in the control group (P=0.002). The chronic disease general self-efficacy (GSE) score in the observation group was higher than those in the control group (P=0.002). The quality of life (MHL) score was in the observation group was higher than those in the control group. The patient satisfaction score in the observation group was higher than those in the control group (P=0.021).
Conclusions: Health education based on behavioral change theories can relieve symptoms of chronic heart failure, and improve patients’ self-efficacy level, self-management ability and patient satisfaction.

Authors: WANG Weilan , XIAO Bingkun , LIU Ziqi , WANG Dongxiao , ZHU Man
Published: May 2019

Background: To survey the prevalence of potential drug-drug interactions (DDIs) between anticancer drugs and non-anticancer drugs and evaluate the risk factors associated with these drug-drug interactions in China.
Methods: All discharged patients in the Department of Oncology were collected from Jun to Dec in 2016 with the Hospital Information System of the Chinese people’s Liberation Army General Hospital. Drugs were screened for interactions by Micromedex solutions database. Descriptive statistics were generated and logistic regression was used to identify the associated factors.
Results: Among 6578 eligible patients, 1979 potential drug interactions were found in 1830 patients (27.82%). The most common drug-drug interaction was cisplatin and furosemide. Erlotinib was most likely to interact with various non-anticancer drugs. Most interactions were classified as pharmacodynamics (71.60%), major severity (97.02%) and were supported by fair documentation evidence (86.21%). In multivariate analysis, increasing number of medications, lung cancer and patients with stage IV had a higher risk for potential drug-drug interactions.
Conclusion: Potential drug-drug interactions between antineoplastic drugs and non-antineoplastic drugs occur frequently in cancer patients of Chinese hospitals. Doctors should fully consider potential risk associated with DDIs. Further research should be performed to evaluate real clinical significance of these drug-drug interactions.
Gender Differences in the Relationship between Living alone and Depressive Symptoms in Elderly Korean Adults
Authors: Bum KIM Young , Hee LEE Seung
Published: May 2019

Background: This study examined gender differences in the relationship between living alone and depressive symptoms in elderly Korean adults and the variables that influence this relationship.
Methods: We conducted a secondary analysis using fourth-wave data from adults 65 yr of age or older who participated in the Korean Longitudinal Study of Aging. Depressive symptoms were measured using the 10-item short-form of the Center for Epidemiological Studies Depression Scale. Multiple logistic regression analyses were used.
Results: After controlling for the factors of formal and informal social activities, financial support from children, employment, activities of daily living, instrumental activities of daily living, self-rated health, frequency of meals, and gender, living alone (AOR=1.45, 95% CI =1.09-1.93, P=0.010) was an independent risk factor that contributed to depressive symptoms in late life. Living alone was more likely to elevate depressive symptoms in older women but not in older men.
Conclusion: Gender differences in the depressive effect of living alone in late life may differ across diverse cultures.

Published: May 2019

Background: Fasciolosis is a shared disease between humans and livestock caused by hepatic trematodes; Fasciola hepatica and F. gigantica. Differentiate between the two species of this genus is essential. High-Resolution Melting (HRM) Analysis represents a new approach to this issue. This method can be performed right after termination of Real-Time PCR. This technique has not been used for identification of adult F. hepatica and F. gigantica genotypes. The aim of this study was to determine Fasciola species by using HRM in isolates taken from Iran, respectively.
Methods: Ninety-three Fasciola spp. samples were collected from infected slaughtered animals in different regions of Iran, including North West (Ardebil Province) and South East (Zahedan Province) during 2016. Genomic DNA from the samples was extracted using a DNA extraction kit and then after Real-Time PCR amplification, HRM was done.
Results: Overall, 59 and 34 isolates were identified as F. hepatica and F. gigantica, respectively. The percentages of each species from animals were as follows: sheep (F. hepatica, 80.39% and F. gigantica, 19.61%), cattle (F. hepatica, 42.85% and F. gigantica, 57.15%).
Conclusion: HRM technique developed in the present study is a powerful, rapid and sensitive technique for epidemiological survey and molecular identification between F. hepatica and F. gigantica.

Vitamin C in fleshy fruits: biosynthesis, recycling, genes, and enzymes
Authors: Tyapkina D. Y. , Kochieva E. Z. , Slugina M. A.
Published: May 2019

L-ascorbic acid (vitamin C) is a plant secondary metabolite that has a variety of functions both in plant tissues and in the human body. Plants are the main source of vitamin C in human nutrition, especially citrus, rose hip, tomato, strawberry, pepper, papaya, kiwi, and currant fruits. However, in spite of the biological significance of L-ascorbic acid, the pathways of its biosynthesis in plants were fully understood only in 2007 by the example of a model plant Arabidopsis thaliana. In the present review, the main biosynthetic pathways of vitamin C are described: the L-galactose pathway, L-gulose pathway, galacturonic and myo-inositol pathway. To date, the best studied is the L-galactose pathway (Smyrnoff–Wheeler pathway). Only for this pathway all the enzymes and the entire cascade of reactions have been described. For other pathways, only hypothetical metabolites are proposed and not all the catalyzing enzymes have been identified. The key genes participating in ascorbic acid biosynthesis and accumulation in fleshy fruits are highlighted. Among them are L-galactose pathway proteins (GDP-mannose phosphorylase (GMP, VTC1), GDP-D-mannose epimerase (GME), GDP-L-galactose phosphorylase (GGP, VTC2/VTC5), L-galactose-1-phosphate phosphatase (GPP/VTC4), L-galactose-1-dehydrogenase (GalDH), and L-galactono1,4-lactone dehydrogenase (GalLDH)); D-galacturonic pathway enzymes (NADPH-dependent D-galacturonate reductase (GalUR)); and proteins, controlling the recycling of ascorbic acid (dehydroascorbate reductase (DHAR1) and monodehydroascorbate reductase (MDHAR)). Until now, there is no clear and unequivocal evidence for the existence of one predominant pathway of vitamin C biosynthesis in fleshy fruits. For example, the L-galactose pathway is predominant in peach and kiwi fruits, whereas the D-galacturonic pathway seems to be the most essential in grape and strawberry fruits. However, in some plants, such as citrus and tomato fruits, there is a switch between different pathways during ripening. It is noted that the final ascorbic acid content in fruits depends not only on biosynthesis but also on the rate of its oxidation and recirculation.

Published: May 2019

The Eurasian wigeon (Mareca penelope) is one of the most numerous migrant species of waterfowl in the Palearctic. Annually, significant part of the world’s wigeon population makes seasonal flights over distances from tens to thousands or more kilometers. According to different estimates based on banding data, five geographic populations of the species were described in the Palearctic. However, distinct borders between the populations have not been identified. At the same time, no phylogeographic studies have been carried out for the complete native range of wigeon so far. In addition to the fundamental importance of such a study, knowledge of the genetic structure of populations is necessary for the development of measures to increase the number of and preserve this valuable game species. The aim of our work was a phylogeographic analysis of the wigeon across its vast native range in the Palearctic including ducks wintering in North America. We examined genetic diversity and differentiation of wigeon populations identified with banding data, phylogenetic relationships of mtDNA haplotypes and demographic history of populations and species as a whole by sequencing a 661 base-pair 5’-fragment of the mitochondrial control region from 195 individual ducks collected throughout the Palearctic and Nearctic. Genetic diversity was high in all studied populations. A reconstruction of haplotypes phylogeny revealed the absence of geographic structure in the data. Nonetheless, analysis of molecular variance (AMOVA) identified two groups of populations: EuropeanSiberian and East Asian. The former included wigeons from Europe, Siberia and the Atlantic coast of North America, and the latter comprised ducks from Russian Far East, Kamchatka Peninsula, Chukotka Autonomous District, the Aleutian Islands, Alaska, and the Pacific coast of North America.
Politiques et pratiques en matière de bois-énergie dans certains pays d’Afrique subsaharienne – un examen critique
Authors: Sola Phosiso , Schure Jolien , Eba’a Atyi Richard , Gumbo Davison , Okeyo Irene
Published: May 2019

L'Afrique subsaharienne reste très dépendante des biocombustibles, qui couvrent 60 % de sa demande énergétique totale. Bien que le bois-énergie soit une source d'énergie importante pour des millions de personnes en Afrique subsaharienne, il est rarement suffisamment reconnu dans les politiques énergétiques. Depuis des décennies, les politiques gouvernementales ont supposé que la croissance économique et l'augmentation des revenus des ménages qui en résulterait entraînerait un passage à des carburants plus "modernes". Cependant, avec des niveaux de pauvreté toujours élevés et le manque d'accès à des sources d'énergie alternatives abordables, cette transition est loin de devenir une réalité. Cet article conceptualise la gouvernance du bois-énergie et analyse les politiques et les mécanismes institutionnels pertinents pour le sous-secteur du bois-énergie dans certains pays : Cameroun, République démocratique du Congo, Kenya et Zambie. Sur la base d'un examen structuré de la littérature, il évalue les politiques et les mécanismes juridiques existants et leur mise en œuvre, dans le contexte des pratiques actuelles le long des chaînes de valeur du bois-énergie dans ces mêmes pays. La principale conclusion est que, bien que le bois-énergie soit de plus en plus reconnu comme une source d'énergie majeure dans la plupart des pays, il est souvent associé à des résultats environnementaux négatifs et à des résultats socio-économiques positifs. Récemment, les gouvernements de plusieurs pays ont élaboré des politiques et des cadres législatifs pour guider, gérer, soutenir et réglementer la production et le commerce du bois-énergie. En dépit des dispositions légales, l'industrie du bois de feu fonctionne en grande partie dans le secteur informel et n'est pas réglementée et/ou réprimée dans certains endroits. La gouvernance des chaînes de valeur du bois-énergie est confrontée à des défis majeurs liés au manque de clarté des arrangements institutionnels et des mécanismes d'application, aux capacités limitées et aux comportements corrompus, ainsi qu'à l'insuffisance des investissements et du financement. Par conséquent, une gouvernance plus intégrée et mieux adaptée est nécessaire pour que les chaînes de valeur durables du bois-énergie deviennent une réalité.

Alors que l’efficacité de la conversion du bois en charbon est souvent considérée comme une question technique de performance des fours, cette étude vise à mettre en lumière le rôle d’un contexte institutionnel favorable et les capacités des acteurs impliqués. Sont d’abord passées en revue les initiatives visant à améliorer la production de charbon de bois dans différents pays d’Afrique subsaharienne. Nous comparons ensuite les données sur les processus de carbonisation dans deux zones en République démocratique du Congo : Yangambi et le Plateau de Bateke. Les principales conclusions sont les suivantes : 1) l’amélioration des techniques de carbonisation permet de réaliser d’importants gains en termes de taux de conversion du bois en charbon, mais le succès dépend en grande partie de l’adéquation des solutions de four en fonction du contexte, de la capacité et de la sensibilisation des producteurs et du contexte institutionnel favorable ; 2) le renforcement des capacités des opérateurs et des autres parties prenantes nécessite des techniques de four efficaces, mais aussi une sensibilisation accrue aux avantages et aux options d’approvisionnement durable, le renforcement des compétences financières et de gestion des organisations de producteurs et l’amélioration du transport, de la manutention et de la commercialisation ; 3) le statut illégal ou informel des producteurs de charbon de bois en Afrique subsaharienne nuit à l’efficacité des processus de production du charbon, tandis qu’un cadre institutionnel adéquat facilite l’accès des producteurs aux permis et au financement, fournit une fiscalité claire avec des incitations pour des pratiques plus durables et relie les exigences techniques en termes de carbonisation aux sources et utilisations finales durables. Le succès ou l’échec des techniques de carbonisation améliorées et les résultats socio-écologiques connexes sont déterminés conjointement par les solutions qui incluent les aspects de renforcement des capacités, d’acceptabilité et d’institutions favorables identifiés dans cet article. La poursuite du développement de ces solutions en partenariat avec les producteurs accroît le potentiel de chaînes de valeur plus durables pour le bois-énergie.

Authors: Agustiono Wahyudi
Published: May 2019

Background: For many years, researches on Business Intelligence (BI) development have been popular in primary industry (trading, telecommunication, and manufacturing). Nevertheless, the academic sector has not been the primary beneficiary. This lack of practices also means there has been limited knowledge relating to the development of BI in the academic sectorObjective: This study presents the development of an Academic Business Intelligence (ABI). Taking an actual ABI development project in a small and medium-sized university in Indonesia context, it specifically sought to understand as to why the university needed an ABI and how it could be developed within the limited resources (funding, IT infrastructure and expertise).Methods: Following the business intelligence development roadmap, this study was able to develop an ABI as an attempt to provide a smart way for generating valuable information from scattered data interactively. It also successfully deployed the newly developed ABI into the existing IT legacy and then run a series of pilot testing involving the intended users.Results: The results showed the acceptance rate was high (87.25%) and suggested that the system found to be usable for conducting students' performance assessment and decision making faster. In short, this study contributes to the growing body of BI development literature by providing empirical evidence on how to successfully develop a BI within the unique context of the academic sector.Conclusion: Considering the findings, this study also draws practical recommendations and highlights a few limitations from which future study could address, especially when developing BI or similar ABI in particular.

Background: Tour recommendation and path planning are the most challenging jobs for tourists as they decide Points of Interest (POI).Objective: To reduce the physical effort of the tourists and recommend them a personalized tour is the main objective of this paper. Most of the time people had to find the places he wants to visit in a difficult way. It kills a lot of time.Methods: To cope with this situation we have used different methodology. First, a greedy algorithm is used for filtering the POIs and BFS (Breadth First Search) algorithm will find POI in terms of user interest. The maximum number of visited POI within a limited time will be considered. Then, the Dijkstra algorithm finds the shortest path from the point of departure to the end of tours.Results:  This work shows its users list of places according to the user's interest in a particular city. It also suggests them places to visit in a range from the location of the user where a user can dynamically change this range and it also suggests nearby places they may want to visit.Conclusion: This tour recommendation system provides its users with a better trip planning and thus makes their holidays enjoyable.
Seasonal differences in Vitis vinifera L. cv. Pinot noir fruit and wine quality in relation to climate
Authors: Blank Magali , Hofmann Marco , Stoll Manfred
Published: May 2019

Aims: A better understanding of the relationship between weather conditions and wine quality would provide tools for assessing the impact of climate change and the potential for adaptation. Most studies rely on assessing wine quality by the price per bottle or by an overall ranking and then establishing general relations to weather conditions. However, such an approach may imply the addition of bias by variable winemaking techniques overcoming vintage effects. The aim of our study was therefore to implement a controlled conditions approach using grape samples from a single vineyard and a standardized micro-scale winemaking technique to produce wines in similar conditions for each vintage over more than a decade. We hope that this data will allow new insights into responses to climatic differences.Methods and results: From 2005 to 2015, data was collected from a vineyard of Hochschule Geisenheim University planted with Vitis vinifera L. cv. Pinot Noir grafted on rootstock SO4 in four field replicates. Weather conditions were recorded together with the major phenological stages, yield, infection of the bunches by Botrytis cinerea bunch rot, and pruning weight. Key primary juice compounds were analyzed and berry phenolics in skins and seeds were determined before harvest. Micro-scale winemaking was developed to produce wines in standardized conditions. The repeatability of the method to assess the extraction of anthocyanins and tannins was shown to be 2–10% and 8–12%, respectively, depending on grape maturity stage. Sugar accumulation was coupled to warmer conditions during the maturation period, and high temperatures after véraison decreased the concentration of malic acid in the juice. The accumulation of primary amino acids (N-OPA) in the juices seemed positively related to warmer conditions between bud break and flowering. Increased temperature, especially before véraison, accompanied by a lack of precipitation was related to an accumulation of tannins in fruit and wine, with a higher accumulation in skins than seeds. The temperature-sensitive anthocyanin accumulation in grapes was coupled to warmer conditions after véraison. These differences in anthocyanin concentration could also be observed in the wine.Conclusions: High-quality vintages were linked to warmer than normal growing seasons and below normal precipitation.Significance and impact of the study: The use of a micro-scale winemaking technique represents an innovative tool to provide detailed information in a controlled and reproducible way. A better understanding of the interaction between weather conditions and berry/wine compounds will help with developing improved winemaking techniques and better adapting to future impacts of climate change.

Minimizing greenhouse gas emissions (GHGE) from public sector meals harbours considerable potential to reduce climate impact. This paper aimed at finding the best possible strategy for reducing GHGE in the Swedish school food supply without compromising its nutritional adequacy, affordability, and cultural acceptability. Prices, amounts, and GHGE of all foods and drinks supplied to three schools over one year were optimized by linear programming. Three models were developed: Model 1 minimized GHGE while constraining relative deviation (RD) from observed food supply; Model 2 minimized total RD while imposing stepwise GHGE reductions; and Model 3 additionally constrained RD to -75% and +200% of the observed value. Model 1 reduced GHGE by 89-95% with an average RD (ARD) from observed food supply of 480-887%. In Model 2, comparable GHGE reductions (80%-95%) at lower ARD (78%-459%) were achieved but with high RDs for individual foods. Model 3 excluded no foods, avoided high RDs, and reduced GHGE by 40% in all schools with ARDs of 7.2-8.1% at 12-15% lower cost. An omnivorous, nutritionally adequate, and affordable school food supply with considerably lower GHGE is achievable with moderate changes to the observed food supply. This method can also be applied in other settings and countries.
Recursive Data Clustering through Finding Vague Solutions
Authors: Monaco Domenico
Published: May 2019

This work is developed over the question ”How to automatically create a good clusteringon spatial dataset with hight different local densities?” opened by previus work of Berzi. To answer the main question, this work describe a approach of recursive clustering pro-cess based on a technique of finding ”vague-solution”, where the output is an hierarchicalclustering of initial dataset. In particularly the the approach is developed and tested on DBSCAN algorithm with large dataset gathered by Google Place in Metropolitan Areaof Milan.  The core solutions developed in this algorithm are condensed in the capacity of gener-ation a Hierarchical Clustering with a recursive select the best solutions in according tothe our goals, previously dfined by some sets of rules. The algorithm described here, and developed in my Master Thesis, rosolve two problem:- When we use an algorithm of clustering that can create a set of differents clustering,but equally valid and don’t know exctly what we must have as good solution, we areled to ask ourselves: ”What are the better?” This obviously depends by our goals, sonow the question is: ”What are our goals?”- The second problem is condesned in the sentence ”Not all clusters can be found inone-shot clustering process, more often we must reapply the process to some partof datataset”, so there we have a second question that this paper answering: ”Howto create clustering of data with ad-hoc processing for each different part of inputdataset?” These questions are resolved by the approaches namend in this work as: Space ofSolutions, Vague-Solution, Vague-Solution finding Method and finaly Recursive Clustering. All of these approach was drafetd and testes algoruthm in mine Master Thesis titled ”Geospatial data analysis for Urban informatics applications: the case of the Google Placeof the City of Milan”.
