Where to Go Next: Modeling Long- and Short-Term User Preferences for Point-of-Interest Recommendation
Authors: Sun Ke , Qian Tieyun , Chen Tong , Liang Yile , Nguyen Quoc Viet Hung , Yin Hongzhi
Published: June 2020

Point-of-Interest (POI) recommendation has been a trending research topic as it generates personalized suggestions on facilities for users from a large number of candidate venues. Since users' check-in records can be viewed as a long sequence, methods based on recurrent neural networks (RNNs) have recently shown promising applicability for this task. However, existing RNN-based methods either neglect users' long-term preferences or overlook the geographical relations among recently visited POIs when modeling users' short-term preferences, thus making the recommendation results unreliable. To address the above limitations, we propose a novel method named Long- and Short-Term Preference Modeling (LSTPM) for next-POI recommendation. In particular, the proposed model consists of a nonlocal network for long-term preference modeling and a geo-dilated RNN for short-term preference learning. Extensive experiments on two real-world datasets demonstrate that our model yields significant improvements over the state-of-the-art methods.
Knowledge Graph Alignment Network with Gated Multi-Hop Neighborhood Aggregation

Published: June 2020

Graph neural networks (GNNs) have emerged as a powerful paradigm for embedding-based entity alignment due to their capability of identifying isomorphic subgraphs. However, in real knowledge graphs (KGs), the counterpart entities usually have non-isomorphic neighborhood structures, which easily causes GNNs to yield different representations for them. To tackle this problem, we propose a new KG alignment network, namely AliNet, aiming at mitigating the non-isomorphism of neighborhood structures in an end-to-end manner. As the direct neighbors of counterpart entities are usually dissimilar due to the schema heterogeneity, AliNet introduces distant neighbors to expand the overlap between their neighborhood structures. It employs an attention mechanism to highlight helpful distant neighbors and reduce noises. Then, it controls the aggregation of both direct and distant neighborhood information using a gating mechanism. We further propose a relation loss to refine entity representations. We perform thorough experiments with detailed ablation studies and analyses on five entity alignment datasets, demonstrating the effectiveness of AliNet.
Multi-Channel Reverse Dictionary Model
Authors: Zhang Lei , Qi Fanchao , Liu Zhiyuan , Wang Yasheng , Liu Qun , Sun Maosong
Published: June 2020

A reverse dictionary takes the description of a target word as input and outputs the target word together with other words that match the description. Existing reverse dictionary methods cannot deal with highly variable input queries and low-frequency target words successfully. Inspired by the description-to-word inference process of humans, we propose the multi-channel reverse dictionary model, which can mitigate the two problems simultaneously. Our model comprises a sentence encoder and multiple predictors. The predictors are expected to identify different characteristics of the target word from the input query. We evaluate our model on English and Chinese datasets including both dictionary definitions and human-written descriptions. Experimental results show that our model achieves the state-of-the-art performance, and even outperforms the most popular commercial reverse dictionary system on the human-written description dataset. We also conduct quantitative analyses and a case study to demonstrate the effectiveness and robustness of our model.

Guided Weak Supervision for Action Recognition with Scarce Data to Assess Skills of Children with Autism
Authors: Pandey Prashant , AP Prathosh , Kohli Manu , Pritchard Josh
Published: June 2020

Diagnostic and intervention methodologies for skill assessment of autism typically requires a clinician repetitively initiating several stimuli and recording the child's response. In this paper, we propose to automate the response measurement through video recording of the scene following the use of Deep Neural models for human action recognition from videos. However, supervised learning of neural networks demand large amounts of annotated data that is hard to come by. This issue is addressed by leveraging the ‘similarities’ between the action categories in publicly available large-scale video action (source) datasets and the dataset of interest. A technique called Guided Weak Supervision is proposed, where every class in the target data is matched to a class in the source data using the principle of posterior likelihood maximization. Subsequently, classifier on the target data is re-trained by augmenting samples from the matched source classes, along with a new loss encouraging inter-class separability. The proposed method is evaluated on two skill assessment autism datasets, SSBD (Sundar Rajagopalan, Dhall, and Goecke 2013) and a real world Autism dataset comprising 37 children of different ages and ethnicity who are diagnosed with autism. Our proposed method is found to improve the performance of the state-of-the-art multi-class human action recognition models in-spite of supervision with scarce data.
Neural Approximate Dynamic Programming for On-Demand Ride-Pooling
Authors: Shah Sanket , Lowalekar Meghna , Varakantham Pradeep
Published: June 2020

On-demand ride-pooling (e.g., UberPool, LyftLine, GrabShare) has recently become popular because of its ability to lower costs for passengers while simultaneously increasing revenue for drivers and aggregation companies (e.g., Uber). Unlike in Taxi on Demand (ToD) services – where a vehicle is assigned one passenger at a time – in on-demand ride-pooling, each vehicle must simultaneously serve multiple passengers with heterogeneous origin and destination pairs without violating any quality constraints. To ensure near real-time response, existing solutions to the real-time ride-pooling problem are myopic in that they optimise the objective (e.g., maximise the number of passengers served) for the current time step without considering the effect such an assignment could have on assignments in future time steps. However, considering the future effects of an assignment that also has to consider what combinations of passenger requests can be assigned to vehicles adds a layer of combinatorial complexity to the already challenging problem of considering future effects in the ToD case.A popular approach that addresses the limitations of myopic assignments in ToD problems is Approximate Dynamic Programming (ADP). Existing ADP methods for ToD can only handle Linear Program (LP) based assignments, however, as the value update relies on dual values from the LP. The assignment problem in ride pooling requires an Integer Linear Program (ILP) that has bad LP relaxations. Therefore, our key technical contribution is in providing a general ADP method that can learn from the ILP based assignment found in ride-pooling. Additionally, we handle the extra combinatorial complexity from combinations of passenger requests by using a Neural Network based approximate value function and show a connection to Deep Reinforcement Learning that allows us to learn this value-function with increased stability and sample-efficiency. We show that our approach easily outperforms leading approaches for on-demand ride-pooling on a real-world dataset by up to 16%, a significant improvement in city-scale transportation problems.
Effect of process parameters on machining EN 47 spring steel through WEDM
Authors: Banerjee Sudip , Panja Bikash , Mitra Soupayan
Published: June 2020

Achieving good material removal rate (MRR) along with better surface roughness is a challenging task for the present machining industry. The present study proposes Taguchi-method-based multiple-response grey relational analysis to find the optimal combination of machining parameters for maximum MRR and minimum surface roughness (R a) in wire electro-discharge machining (WEDM) of EN 47 spring steel. The effects of four process parameters – namely, pulse-on time, pulse-off time, gap voltage and wire feed – on the machining characteristics (MRR and R a) were studied with the help of an L27 orthogonal array, which was used to study the main effect as well as the interaction effect of the parameters. The grey relational grade was the performance index which is used to study the behaviour of machining parameters in WEDM of EN 47 spring steel with respect to the MRR and R a. Signal-to-noise ratio analysis and analysis of variance are done by taking the grey relational grade as the combined response. It is observed that the pulse-on time was the most significant process parameter, whereas the pulse-off time had a moderate effect on the MRR and R a. Moreover, significant interactions were found in all three cases in controlling MRR and R a. The surface morphology and composition were studied with the help of scanning electron microscopy and chemical analysis.

Published: June 2020

Significance Statement

In populations, mean GFR is lower in older age, but whether healthy aging is associated with preserved rather than lower GFR in some individuals is unknown. In a meta-analysis of three large European-based cohorts, the authors investigated the cross-sectional association of being healthy (defined as having no major chronic disease or risk factors for CKD), age, and iohexol clearance measurements. The mean and the 97.5th percentile of the GFR distribution were higher in older persons who were healthy than in those who were unhealthy, but lower than in middle-aged people who were healthy. The GFR-age association was more negative in women than in men. These results suggest that, although being healthy is associated with higher GFR in old age, healthy aging is probably not associated with preserved GFR in old age.

Background

Population mean GFR is lower in older age, but it is unknown whether healthy aging is associated with preserved rather than lower GFR in some individuals.

Methods

We investigated the cross-sectional association between measured GFR, age, and health in persons aged 50–97 years in the general population through a meta-analysis of iohexol clearance measurements in three large European population-based cohorts. We defined a healthy person as having no major chronic disease or risk factors for CKD and all others as unhealthy. We used a generalized additive model to study GFR distribution by age according to health status.

Results

There were 935 (22%) GFR measurements in persons who were healthy and 3274 (78%) in persons who were unhealthy. The mean GFR was lower in older age by −0.72 ml/min per 1.73 m2 per year (95% confidence interval [95% CI], −0.96 to −0.48) for men who were healthy versus −1.03 ml/min per 1.73 m2 per year (95% CI, −1.25 to −0.80) for men who were unhealthy, and by −0.92 ml/min per 1.73 m2 per year (95% CI, −1.14 to −0.70) for women who were healthy versus −1.22 ml/min per 1.73 m2 per year (95% CI, −1.43 to −1.02) for women who were unhealthy. For healthy and unhealthy people of both sexes, both the 97.5th and 2.5th GFR percentiles exhibited a negative linear association with age.

Conclusions

Healthy aging is associated with a higher mean GFR compared with unhealthy aging. However, both the mean and 97.5 percentiles of the GFR distribution are lower in older persons who are healthy than in middle-aged persons who are healthy. This suggests that healthy aging is not associated with preserved GFR in old age.
Buriti Oil Emulsions as Affected by Soy Protein Isolate/High-Methoxyl Pectin Ratio, Oil Content and Homogenization Pressure
Authors: Freitas Mírian Luisa Faria , Ribeiro Ana Paula Badan , Nicoletti Vânia Regina
Published: June 2020

Research background. Emulsion technology is a suitable way of encapsulating, protecting and releasing hydrophobic bioactive compounds for application in food industries, but they are thermodynamically unstable systems. Good results have been achieved for emulsions stabilized by protein-polysaccharide complexes subjected to high-pressure homogenization. Improved stabilization of oil-in-water emulsions results from electrostatic complexes formed between proteins and polysaccharides at pH lower than the protein isoelectric point, which adsorb at the oil-water interface. In addition, polysaccharides contribute to emulsion stability by increasing viscosity of the continuous phase. The aim of this work is to investigate the production of carotenoid-rich buriti oil emulsions using soy protein isolate and high-methoxyl pectin as stabilizers. Experimental approach. Using a rotatable central composite experimental design, we assessed the effects of oil content, soy protein isolate/high-methoxyl pectin ratio and homogenization pressure on the stability, droplet size, electrical conductivity, electrical charge, microstructure and rheological behaviour of the emulsions. Results and conclusions. An optimized emulsion was produced with 28 % buriti oil, 55 % soy protein isolate, and homogenization pressure of 380·105 Pa. This emulsion was stable for at least seven days, presenting reduced average droplet size, low electrical conductivity and high modulus of negative charges. The mechanical spectra showed that the emulsion behaved as a viscoelastic gel under oscillatory, non-destructive shearing, whereas shearthinning behaviour took place under steady shear conditions. Novelty and scientific contribution. The optimized buriti oil emulsions stabilized by soy protein isolate and high-methoxyl pectin could be suitable for fat substitution, energy reduction and carotenoid enrichment in food products, such as dairy and bakery products, ice cream, salad sauces and vegetable-based cream.
Demistifying Hate Speech under the PEPUDA
Authors: Geldenhuys Judith , Kelly-Louw Michelle
Published: June 2020

The factual matrix that is considered in each hate speech case differs from that in the next. However, certain factors always remain key in the process of balancing the different constitutional rights at play: who the victim is, who the perpetrator is and the nature of the expression. Additional factors to be considered in deciding whether an expression constitutes hate speech include: historical associations; who the utterer is as against the victim(s); the audience that is addressed and where the utterance is made; and the prevailing social conditions. How South African courts and the South African Human Rights Commission factor in these specific issues in assessing whether an utterance constitutes hate speech is examined in this contribution. Applicable international law principles and comparable foreign law reveal certain areas of the South African hate speech protection requiring refinement.
Lenguaje y formación humanística
Authors: Cárdenas Paéz Alfonso , Chacón Chacón Adriana
Published: June 2020

Este artículo de reflexión se basa en la investigación “Un marco semiótico discursivo y sociocognitivo para la enseñanza del lenguaje”. Dicho marco reconoce que el ser humano es un ser de acción y de pasión, cuyos intereses se rigen por principios éticos, según los cuales prevalece la diferencia no indiferente. Por tanto, el objeto del artículo es indagar acerca de las proyecciones educativas que la concepción del lenguaje del pensador ruso Mijaíl Bajtín pueda tener en la formación humanística, desde una visión dialógica y ética del lenguaje, en la cual prevalece el concepto de doble alteridad. En atención a esto y a tenor de las nociones de arquitectónica, extraposición y cronotopo, el artículo analiza diversos ángulos de la configuración de sentido; asimismo, estudia su incidencia en la constitución del sujeto, con miras a establecer la formación como un problema pedagógico asociado a valores.
La canción social latinoamericana en Calle 13. Un estudio desde la perspectiva histórica discursiva
Authors: Moreno Pineda Víctor Alfonso , Silgado Ramos Alex , Pérez Córdoba Alder Luis
Published: June 2020

Este artículo de investigación presenta el análisis de los recursos lingüísticos, las estrategias discursivas y retóricas presentes en las letras del grupo musical Calle 13, con el fin de ubicarlas dentro de la tradición de la canción social latinoamericana. Para ello, se circunscribe a la perspectiva histórica discursiva, enfoque teórico metodológico que pertenece a la corriente multidisciplinar del ACD (Wodak, 2003; 2011). Partiendo de García Canclini (1977; 1990), se define el concepto de canción social latinoamericana como una forma de arte popular, al que pertenece la propuesta lírico-musical de Calle 13. El corpus analizado está constituido por nueve canciones de la banda, tomadas de sus álbumes y colaboraciones. El trabajo plantea como categorías de análisis las macroestructuras semánticas, la intertextualidad e interdiscursividad, las figuras retóricas y los topoi. Al final se concluye que Calle 13 participa de la canción social latinoamericana en la medida en que sus letras constituyen una posibilidad más de exaltación de lo latinoamericano y de apropiación de los valores culturales nacionales y locales; además de una voz de resistencia, de denuncia y de lucha antiimperialista.
Sentidos de lo común en la educación comunitaria: a propósito de la Universidad Pedagógica Nacional
Authors: Aguilera Morales Alcira , Clavijo Ramírez Amadeo
Published: June 2020

El artículo es producto del proyecto de investigación “Construcción de la memoria colectiva de tres propuestas de formación en educación comunitaria de la UPN”. El objetivo del proyecto fue recuperar la memoria de la educación comunitaria en la Universidad Pedagógica Nacional de Colombia (UPN). En esta tarea se acudió a la reconstrucción de la trayectoria histórica de tres experiencias de educación comunitaria adelantadas en la upn desde la década de los setenta hasta finales del siglo XX. Así, a partir de la recuperación y el análisis de las fuentes orales y documentales se aportó a la conceptualización de una de las tradiciones pedagógicas de la universidad. En este rastreo histórico indagamos por la relación entre los sentidos de lo común y la educación comunitaria a partir de tres problematizaciones: sentidos formativos en términos ético-políticos; lo común como insurgente epistémico; y lo solidario en la educación comunitaria. Ellos no solo permiten la visibilización de estas experiencias, sino que además nos llevan a nuevas claves para leerlas con la intención de proyectar discusiones que se adelantan actualmente en el campo de la educación comunitaria en el ámbito universitario.
El saber escolar de las artes en la escuela pública (1850-1900)
Authors: Cárdenas Paéz Óscar Leonardo , Cárdenas Forero Marco Tulio , Hernández Castillo Camila Andrea
Published: June 2020

El presente artículo de reflexión cualitativa es una aproximación a la construcción de la historia del saber escolar de las artes en la segunda mitad del siglo xix. Metodológicamente, empleó el enfoque arqueogenealógico de Michel Foucault y, enmarcado en el proyecto de investigación “Los saberes artísticos en la escuela pública colombiana del siglo XIX”, continúa y complementa el trabajo iniciado sobre la construcción de la historia del saber de las artes en la escuela pública de la primera mitad del siglo xix, analizando su desarrollo posterior, en términos de su procedencia, función y funcionamiento en la escuela pública entre 1850 – 1900. Con esto, se pretende dar cuenta de las condiciones históricas que impulsaron la introducción, instalación y constitución definitiva del saber de las artes como un saber escolar dentro de la estructura curricular pública; la transfiguraciónde los modos de la enseñanza escolar, y la forma en que fue asumido bajo el término de asignaturas académicas del dibujo, el canto y la música, que fueron empleadas como tecnologías de disciplinamiento, conforme con la racionalidad de la época, para encauzar los comportamientos de los sujetos escolares y su constitución como subjetividades dóciles, adiestradas y normalizadas. Para lograr este objetivo, se constituyó, en primera instancia, un archivo documental que luego fue recopilado en fichas de registro del que se rastrearon los vestigiosy se determinaron las condiciones de poder que se instituyeron para impulsar la emergencia de estos, y de los cuales se extrajeron los enunciados, los espacios, los conceptos y los juegos de poder que permitieron analizar el objeto de estudio formulado.
Alienación, enseñanza y separación del Otro
Authors: Sotelo Céspedes Aída
Published: June 2020

Este texto, producto de mi reflexión, describe el proceso de sometimiento al lenguaje que constituye al sujeto, para dar importancia a la diferencia entre sus dos fases: 1) el sujeto hablado se aliena en los significantes del primer Otro, 2) separarse de esos significantes lo libera. El caso de los hermanos Castaño Gil en Colombia, tal como lo relata Manuel Castaño, permite preguntar si una enseñanza movilizaría la alienación inicial del sujeto al gran Otro del lenguaje transmitidopor la familia, es decir, si haría alguna separación. Separación, que concepto psicoanalítico queaquí pretendo examinar.
El debilitamiento teórico de la pedagogía en la posmodernidad
Authors: Álvarez Gallego Alejandro
Published: June 2020

Este artículo de reflexión es derivado del proyecto de investigación “Paradigmas de la pedagogía en Colombia: 1970-2000”, financiado por Colciencias. El subproyecto de investigación que dirigí se ocupó de buscar los aportes de la educación popular al campo de la pedagogía. En el transcursode la investigación nos encontramos con unos enunciados provenientes de la educación popular que coincidían casi literalmente con los discursos que agencian hoy las grandes corporaciones. Este hallazgo nos llevó a plantear que la pedagogía hoy también es producida en y para el capital. La pedagogía está enraizada en unos principios que en el pasado hacían parte de los discursosemancipadores que buscaban la formación de ciudadanos críticos capaces de cuestionar el sistema capitalista. Queda planteado el interrogante: ¿qué sería entonces hoy pensar la pedagogía?

Para ello se destaca el lugar de la adolescencia en el campo conceptual de la teoría psicoanalítica explicando como el sujeto, para su constitución, supera los impases a los que es sometido por la irrupción de la pubertad recorriendo, a su manera, y con sus recursos este pasaje de transición.
A ciência e o sujeito da psicanálise
Authors: Cabral André Fernando Gil Alcon
Published: June 2020

Este escrito visa debater em que medida o sujeito com o qual a psicanálise opera pode ser visto como o sujeito da ciência. Primeiramente, retomamos a influência de Galileu e Descartes para compreender o formalismo matemático da ciência moderna. No racionalismo, o cogito representa a reciprocidade entre o ser matemático e a verdade. Em seguida, interpretamos o conceito de sujeito como exclusão interna ao objeto a, pois, trata-se de sustentar o sujeito como incalculável. Eis, que a partir de uma torção na própria ciência moderna, o autor apresenta a verdade como causa da ciência psicanalítica.  Veremos que Lacan formaliza a causa material pela divisão entre saber e verdade.
Electricity demand forecasting in industrial and residential facilities using ensemble machine learning
Authors: Porteiro Rodrigo , Hernández-Callejo Luis , Nesmachnow Sergio
Published: June 2020

This article presents electricity demand forecasting models for industrial and residential facilities, developed using ensemble machine learning strategies. Short term electricity demand forecasting is beneficial for both consumers and suppliers, as it allows improving energy efficiency policies and the rational use of resources. Computational intelligence models are developed for day-ahead electricity demand forecasting. An ensemble strategy is applied to build the day-ahead forecasting model based on several one-hour models. Three steps of data preprocessing are carried out, including treating missing values, removing outliers, and standardization. Feature extraction is performed to reduce overfitting, reducing the training time and improving the accuracy. The best model is optimized using grid search strategies on hyperparameter space. Then, an ensemble of 24 instances is generated to build the complete day-ahead forecasting model. Considering the computational complexity of the applied techniques, they are developed and evaluated on the National Supercomputing Center (Cluster-UY), Uruguay. Three different real data sets are used for evaluation: an industrial park in Burgos (Spain), the total electricity demand for Uruguay, and demand from a distribution substation in Montevideo (Uruguay). Standard performance metrics are applied to evaluate the proposed models. The main results indicate that the best day ahead model based on ExtraTreesRegressor has a mean absolute percentage error of 2:55% on industrial data, 5:17% on total consumption data and 9:09% on substation data.
Efficiency of underground retention systems and reduction of urban floods in Tepic, Mexico
Authors: Ramírez-Quele German Antonio , González-Pérez Mario Guadalupe , Flores-Vilchez Fernando , Asprilla-Lara Yefer , Rodríguez-Rodríguez Jesús
Published: June 2020

Many cities in Mexico experience recurrent floods, caused by changes in land use, the modification of surface and land runoff, the artificialization of areas initially intended for infiltration and recharge of groundwater and, in general, the insufficiency and deficiency of the local networks of urban drainage, incapable to evacuate the annual surpluses of precipitation. In this sense, the objective of this study evaluates the efficiency of an underground system of retention of rainwater in one of the main avenues of the city of Tepic, Mexico: Avenida Tecnologico. To this end, an analysis of the thematic contents and on-site inspection assisted by geographic information systems is carried out. Based on the systems approach and the logic of a qualitative model, it is concluded that the capacity of urban storm water networks for water evacuation is exceeded dimensionally. Also, it can be observed that retention systems can mitigate the urban entropy generated by the floods.
Hungarian Gypsy Musician’s National Association: Battles Faced by Gypsy Musicians in Hungary during the Interwar Years
Authors: Hajnáczky Tamás
Published: June 2020

The governments of the Horthy era did not formulate a central Gypsy policy and, consequently, the so-called ‘Gypsy issue’ fell fully into the hands of the assigned ministries and local authorities. The public authorities acted at their own discretion: Largely, they acted according to their basic tasks and understanding, or simply ignored the issue. As a result, the Ministry of the Interior and the Ministry of Welfare and Labour were the decisive authorities in this issue. Mainly law enforcement dealt with travelling Gypsies—a small portion of the estimated one hundred thousand Gypsies living in Hungary—the majority of whom lived in ‘colonies’ and were dealt with as an issue of public health. Regarding Gypsies, the same era is frequently judged by the legal action affecting these travellers and the often criticised measures regulating public security and health. The foundation of the Hungarian Gypsy Musicians’ National Association, which intended to represent the interests of nearly ten thousand Gypsy musicians, somewhat changed the picture that had developed, since the organisation enjoyed the full support of the heads of the Ministry of the Interior and the city of Budapest. Regulations were enacted to protect their interests and initiatives. Behind the patronage, one might note, was that after the Treaty of Trianon Gypsy music became part of irredentist ideology and the revisionist movement, and therefore the interests and claims of the Gypsy musicians fully fitted the age. The topic is very important for social inclusion today because Gypsy music continues to be considered part of Hungarian cultural heritage and thus gives Gypsies work and integration opportunities.
Images of Roma through the Language of Bulgarian State Archives
Authors: Marinov Aleksandar G.
Published: June 2020

This research has been carried out as part of the RomaInterbellum Project which studies the Roma civic emancipation between World War I and World War II. Trawling through the Bulgarian archival documents on Roma in this time period, a reader cannot help but begin to form a certain image about the Tsigani, the term with which Roma have been popularly referred to in the archives. Unsurprisingly, this image does not seem to differ much from the one of today—that of the uneducated, dirty, foreign, and that pose a threat not only to the prosperity and well-being of the Bulgarian population and culture at large but also to the state and the economy. The research is based on archived files, letters of complaints from Bulgarian citizens and other documents sourced from Bulgarian state archives. The article analyses the words and language employed in the archived documents, the connotations they bear and the images they build. It also tries to show how, in the interwar period, this dominant language was utilised by Roma individuals and leaders in order to react, counter and protect their image and future. More importantly, they sought ways to build a better integrated Roma society through the establishment of own organisations and associations. Understanding this historical narrative from the interwar period is essential in advancing knowledge of many major issues surrounding the Roma today, such as housing, health and their social inclusion.
Simultaneous Determination Of Six Parabens In Cosmetics By A New High Performance Liquid Chromatography Method With Fluorescence Detection
Authors: Yılmaz Pelin Kцseoğlu , Tokat Mehmet Akif
Published: June 2020

In this study, a new high performance liquid chromatography method with fluorescence detection was developed and validated for the simultaneous determination of methyl paraben, ethyl paraben, propyl paraben, isopropyl paraben, butyl paraben and benzyl paraben in cosmetics. Separations were achieved using a C18 guard column (2.1 Ч 10 mm, 3 µm) and a C18 analytical column (2.1 Ч 150 mm, 3 µm). Isocratic elution was applied with a mobile phase consisting of 45 % aqueous o-phosphoric acid solution (0.08 %) and 55 % methanol/water mixture (90 : 10 v/v). The excitation and the emission wavelengths were 254 and 310 nm, respectively. Column temperature was fixed at 40 єC. The linear range was 0.50-10.00 μg/mL for all of the parabens. Limits of detection and quantification were in the range of 0.29-0.32 μg/mL and 0.88-0.97 μg/ mL, respectively. Precision and accuracy values were calculated by analysis results of standard solutions at 0.50, 2.50 and 10.00 μg/mL. The developed and validated method was applied for simultaneous quantitative determination of six paraben species in cosmetic tonic and micellar water samples successfully.

La gestión de mercadeo en los empresarios del caribe colombiano 1900-1950: un análisis historiográfico
Authors: González-Díaz Jaime Eduardo , Brito-Carrillo Clara Judith , Rincón-Quintero Yanyn Aurora
Published: June 2020

The objective of this article is to describe the characteristics of the marketing management applied by the entrepreneurs of the Colombian Caribbean in the period 1900-1950. The implemented research methodology used exclusively secondary sources of information consisting of the life stories of entrepreneurs Daniel Lemaitre, Diego Martínez Camargo, the Vélez Daníes brothers, José Vicente Mogollón, the Pombo brothers, Evaristo Obregón, Rafael del Castillo, and the Román family. Each of these cases (entrepreneurs) constituted a unit of analysis; information processing was carried out through a triangulation of methods: bibliographic records, thematic analysis matrices and lexicometric tables (text mining), which sought to identify dimensions of the marketing variable as product, price, promotion, and distribution. We can conclude from the fndings that the marketing management applied by the entrepreneurs studied emphasized sales management, pricing, and distribution, which fts into the periods of identifcation and functionalist of marketing development (1900 - 1945).

The theoretical framework is based on the theory of Development Potentials, a mixed methodology was applied and the sample consisted of 100 visitors. It was concluded that the needs prevail over the capacities, and that the actions exceed the opportunities, so that their achievements are low, being the most valued the oﬀer itself, the organization of the sector and the surveillance, and among the least valued the administration, the health service, roads and transportation. Among the average aspects of the perception of the tourist resource are the logistics, the attention to the tourist, the infrastructure, the training of guides and the lodging of visitors. The indicators that gained the most weight were promotion and publicity, government support and the promotion of microenterprises. It is concluded that the evaluated site is clearly identifed as a tourist oﬀer in view of the opportunities oﬀered by the FTA, although its potentialities are valued at 42% of development, which is a low level.

Peace News and Radical Disability Writing in 1970s Britain: Perceptions of Welfare and the Welfare State
Authors: Hampton Jameel
Published: June 2020

The 1970s were an important decade for disability policy in Britain. The 1970 Chronically Sick and Disabled Persons Act promised services for all disabled people and a series of cash benefits appeared to comprise a national disability income. By the 1980s, however, these measures had failed, and some disabled people had taken radical stances against the perceived failures of capitalism. This article shows that radical views amongst disabled people began earlier and were more common than has been assumed. It examines Peace News, a prominent activist publication, as evidence of this phenomenon. Disabled people in the 1970s became radicalised in response to traditional failures of British welfare and recent failures of the welfare state. They self-identified as a minority group—alongside homosexuals and ethnic minorities—and fought against discrimination. Unlike major disability organisations in the 1970s, disabled people had a militant approach to improving their welfare and their position in the welfare state.

As implicações dos grandes projetos desenvolvimentistas envolvem o uso de recursos naturais e é propagado como propulsores do desenvolvimento local. Nesse sentido, o presente artigo analisa o desenvolvimento local e os efeitos pós barragem a partir da percepção dos atores que vivenciaram o processo de implementação de hidrelétricas e que vivenciam suas implicações, utilizando como recorte da pesquisa, 14 municípios impactados por três grandes empreendimentos hidrelétricos (Peixe Angical, São Salvador e Estreito), instalados no rio Tocantins. Foram realizadas 54 entrevistas semiestruturadas e analisadas por meio do Discurso do Sujeito Coletivo (DSC). Os resultados apontam que, a implantação desses projetos como um impulsionador para o desenvolvimento local, não cumpriram seu papel. Os atores relatam que, as mudanças e os impactos ocasionados transcendem ao incremento na arrecadação e na geração de energia, além disso, evidenciam as consequências dos efeitos pós-barragem e não reconhecem o desenvolvimento advindo desses empreendimentos, pelo contrário, relatam fortes pontos desfavoráveis ao empreendimento.
Deveres Humanos Fundamentais: um olhar sobre a face oculta da era dos direitos
Authors: Veronese Osmar , Lyra José Francisco Dias da Costa , Preis Marco Antônio
Published: June 2020

Direitos e deveres se constituem nas duas faces de uma moeda que sustenta o Estado Constitucional, tanto que não existem direitos sem deveres, tampouco deveres sem direitos, seja por não ser concebível um regime democrático assentado na exigência unilateral de deveres, seja por não haver garantia jurídica ou fática às declarações de direitos sem o cumprimento de deveres. A partir da constatação de que o tema dos deveres fundamentais é um dos mais esquecidos do constitucionalismo contemporâneo, investiga-se sua importância para integração do estatuto jusfundamental da pessoa humana, equilibrado entre direitos e deveres humanos, como resposta à crítica sobre o discurso quantitativo e à crise de eficácia dos direitos fundamentais. O artigo explora algumas aproximações conceituais, busca delinear as principais características dos deveres fundamentais como categoria jurídica autônoma, seu alcance, interpretação e limites para, alfim, sob o paradigma da solidariedade, verificar os contributos desse resgate para o desenvolvimento da cidadania e da democracia, bem como para conferir-se maior eficácia aos direitos fundamentais.
