Gait Recognition Using Optical Motion Capture: A Decision Fusion Based Method
Authors: Wang Li , Li Yajun , Xiong Fei , Zhang Wenyu
Published: May 2021

Human identification based on motion capture data has received signification attentions for its wide applications in authentication and surveillance systems. The optical motion capture system (OMCS) can dynamically capture the high-precision three-dimensional locations of optical trackers that are implemented on a human body, but its potential in applications on gait recognition has not been studied in existing works. On the other hand, a typical OMCS can only support one player one time, which limits its capability and efficiency. In this paper, our goals are investigating the performance of OMCS-based gait recognition performance, and realizing gait recognition in OMCS such that it can support multiple players at the same time. We develop a gait recognition method based on decision fusion, and it includes the following four steps: feature extraction, unreliable feature calibration, classification of single motion frame, and decision fusion of multiple motion frame. We use kernel extreme learning machine (KELM) for single motion classification, and in particular we propose a reliability weighted sum (RWS) decision fusion method to combine the fuzzy decisions of the motion frames. We demonstrate the performance of the proposed method by using walking gait data collected from 76 participants, and results show that KELM significantly outperforms support vector machine (SVM) and random forest in the single motion frame classification task, and demonstrate that the proposed RWS decision fusion rule can achieve better fusion accuracy compared with conventional fusion rules. Our results also show that, with 10 motion trackers that are implemented on lower body locations, the proposed method can achieve 100% validation accuracy with less than 50 gait motion frames.
Force-Free Control for Direct Teaching of a Surgical Assistant Robot End Effector with Wire-Driven Bidirectional Telescopic Mechanism
Authors: Zhang Youqiang , Jeong Cheol-Su , Kim Minhyo , Jin Sangrok
Published: May 2021

This paper shows the design and modeling of an end effector with a bidirectional telescopic mechanism to allow a surgical assistant robot to hold and handle surgical instruments. It also presents a force-free control algorithm for the direct teaching of end effectors. The bidirectional telescopic mechanism can actively transmit force both upwards and downwards by staggering the wires on both sides. In order to estimate and control torque via motor current without a force/torque sensor, the gravity model and friction model of the device are derived through repeated experiments. The LuGre model is applied to the friction model, and the static and dynamic parameters are obtained using a curve fitting function and a genetic algorithm. Direct teaching control is designed using a force-free control algorithm that compensates for the estimated torque from the motor current for gravity and friction, and then converts it into a position control input. Direct teaching operation sensitivity is verified through hand-guiding experiments.

Published: May 2021

Many people live under stressful conditions which has an adverse effect on their health. Human stress, especially long-term one, can lead to a serious illness. Therefore, monitoring of human stress influence can be very useful. We can monitor stress in strictly controlled laboratory conditions, but it is time-consuming and does not capture reactions, on everyday stressors or in natural environment using wearable sensors, but with limited accuracy. Therefore, we began to analyze the current state of promising wearable stress-meters and the latest advances in the record of related physiological variables. Based on these results, we present the concept of an accurate, reliable and easier to use telemedicine device for long-term monitoring of people in a real life. In our concept, we ratify with two synchronized devices, one on the finger and the second on the chest. The results will be obtained from several physiological variables including electrodermal activity, heart rate and respiration, body temperature, blood pressure and others. All these variables will be measured using a coherent multi-sensors device. Our goal is to show possibilities and trends towards the production of new telemedicine equipment and thus, opening the door to a widespread application of human stress-meters.

Published: May 2021

Diesel–Electric Propulsion (DEP) has been widely used for the propulsion of various ship types including cruise ships. Considering the potential consequences of blackouts, especially on cruise ships, it is essential to design and operate the ships’ power plants for avoiding and preventing such events. This study aims at implementing a comprehensive safety analysis for a cruise ship Diesel–Electric Propulsion (DEP) plant focusing on blackout events. The Combinatorial Approach to Safety Analysis (CASA) method is used to develop Fault Trees considering the blackout as the top event, and subsequently estimate the blackout frequency as well as implement importance analysis. The derived results demonstrate that the overall blackout frequency is close to corresponding values reported in the pertinent literature as well as estimations based on available accident investigations. This study deduces that the blackout frequency depends on the number of operating Diesel Generator (DG) sets, the DG set’s loading profile, the amount of electrical load that can be tripped during overload conditions and the plant operation phase. In addition, failures of the engine auxiliary systems and the fast-electrical load reduction functions, as well as the power generation control components, are identified as important. This study demonstrates the applicability of the CASA method to complex marine systems and reveals the parameters influencing the investigated system blackout frequency, thus providing better insights for these systems’ safety analysis and enhancement.

Published: May 2021

Cooperative intelligent transport systems (C-ITS) are expected to considerably influence road safety, traffic efficiency and comfort. Nevertheless, their market penetration is still limited, on the one hand due to the high costs of installation and maintenance of the infrastructures and, on the other hand, due to the price of support automated driving functions. A breakthrough C-ITS technological solution was studied, designed, built and tested that is based on the implementation of custom low-cost on-road platforms (named “strips”) that embed micro/nano sensors, communication technologies and energy harvesting to shift intelligence from the vehicle to the road infrastructure. The strips, through a V2X and LTE communication gateway, transmit real-time, reliable and accurate information at lane level about the environmental and road condition, the traffic and the other road users’ position and speed. The exchanged information supports a series of C-ITS functions and services extending equipped vehicles capabilities and providing similar functions to non-equipped ones (including powered two wheelers). The general framework and the technological solution proposed is presented and the results of the field trials, conducted in three pilot sites around Europe, quantify the promising system performance as well as the positive effects of the C-ITS applications developed and tested on driver/rider’s behavior.
Rider Perceptions of an On-Demand Microtransit Service in Salt Lake County, Utah
Authors: Macfarlane Gregory S. , Hunter Christian , Martinez Austin , Smith Elizabeth
Published: May 2021

On-demand microtransit services are frequently seen as an important tool in supporting first and last mile operations surrounding fixed route high frequency transit facilities, but questions remain surrounding who will use these novel services and for what purposes. In November 2019, the Utah Transit Authority launched an on-demand microtransit service in south Salt Lake County in partnership with a private mobility operator. This paper reports the results of an expressed preferences survey of 130 transit riders in the microtransit service area that was collected before and immediately after the service launched. There is not a clear relationship between current transit access mode and expressed willingness to use microtransit, although some responses from new riders indicate the novel service competes most directly with commercial transportation network company operations. The survey responses also reveal younger passengers express a more than expected willingness to use microtransit, middle-aged passengers a less than expected willingness, and older passengers neutral or no expressed opinion. The results suggest additional relationships between household size and transit use frequency, but further research is necessary. The effect of other user characteristics, including income and automobile availability, is less statistically clear and requires further research.
It’s a Hard-Knock Life: Child Labor Practices and Compliance with IMF Agreements
Authors: Mark Brendan Skip , Ye Huei-Jyun , Foote Andrew , Crippin Tiffani
Published: May 2021

How does IMF lending impact child labor? We argue that, as compliance with IMF reforms increases, child labor increases. IMF loans can help governments avoid bankruptcy, prevent debt defaults, and credibly signal a commitment to pro-market reforms which should generate trade and investment. However, IMF policies associated with revenue and social policies can have negative impacts on child labor. Education reforms undermine the quality of schooling, making child labor more likely. Healthcare reforms undermine the quality of healthcare; when parents are ill or injured, their children are more likely to enter the workforce to make up for lost income. Similarly, social safety net reforms reduce the ability of families to access a safety net during times of hardship and make it more likely that children are pushed into the labor market to keep families afloat. To test our argument, we use a control function selection model on a sample of 70 IMF borrowers between 2002 and 2016. Using new datasets on IMF compliance and child labor, we find that increased compliance with IMF reforms worsens child labor practices. Revenue and social policy compliance in particular are associated with an increase in child labor.

Published: May 2021

The family represents the cause of as well as the solution to childhood overweight in many family-based childhood weight management interventions. Involving the family also entails involving the individual family members’ experiences with, attitudes towards, and understandings of obesity. This study explores how families with life-long experiences of overweight manage and experience a family-based childhood weight management intervention in Northern Zealand in Denmark. The analysis is focused on family narratives and their temporal character. The families’ narratives about overweight and past weight management interventions are crucial to how they understand and manage the present intervention. Additionally, the families expect the focus on weight management to continue to be a constant part of their everyday life. The paper concludes that the understanding of weight management in interventions should take its point of departure in the life-world, which the individual family creates through members’ narratives about overweight.
A Novel Approach for Comparison of Reception Performance in a Technique Test and Small-Sided Games
Authors: Sørensen Arne , Sørensen Vidar , Dalen Terje
Published: May 2021

The purpose of this study was to evaluate the correlation between soccer players’ performance of receptions of passes in tests of both isolated technical skills and more match-realistic situations in small-sided games (SSGs). In addition, this study investigated whether the involvement in SSGs (number of receptions) correlated with the quality of receptions in the respective SSGs. The participants were 13 male outfield youth soccer players from teams in the first division of the regional U18 league. The quality of receptions was scored by educated coaches according to set criteria of performance. Statistical analyses of correlations were determined using Spearman’s rank-order correlation coefficient (rs). The main results were (1) a significant correlation in the quality of ball reception between 4vs1 SSGs and 5vs5 SSGs (rs = −0.61, p < 0.01) and (2) a trend towards moderate correlation between the quality of ball reception using a ball projection machine and 5vs5 SSGs (rs = −0.48, p = 0.10). (3) A significant correlation was found between the number of receptions in 5vs5 SSGs and the quality score of receptions in 5vs5 SSGs (rs = −0.70, p < 0.01). The trend towards moderate correlations between 5vs5 SSGs and the isolated technical reception test could imply the importance of training in the technical aspects of ball reception. Moreover, it seems as though the players with the best reception performance are the players who are most involved in SSGs, that is, having the most receptions.
A Study of the Factors Influencing the Residential Preferences of the Elderly in China
Authors: Li Hui , Duan Chengyun , Chunyu Miao David
Published: May 2021

The global aging problem has a serious impact on the sustainable development of society. China has become the country with the largest aging population in the world, 1.75 times that of the EU and 3.01 times that of the United States. Therefore, the question of how to develop elderly care services and institutions in China is critical. Based on data from the China Health and Retirement Longitudinal Study (CHARLS), this paper details the residential preferences of the elderly, and uses a multinomial logistic regression model to analyze the influence of education level, health status, and income level on the residential preferences of the elderly in China. The results of the study are as follows: (1) From a spatial point of view, the residential preference of “living together” gradually increases from the northeast to the southwest. As for the choice of “nursing home”, northerners prefer to live in nursing homes more than southerners, especially in the northeast. (2) There are many personal factors that significantly affect housing preferences, such as education level, health status, income level, etc. (3) The development of socialized elderly care institutions should fully consider the preferences of the elderly. There are big differences in residential preferences in different regions and different cities, so the development of elderly care services should be adapted to local conditions.

Published: May 2021

Microplastics (MPs) are ubiquitous and persistent pollutants, and have been detected in a wide variety of media, from soils to aquatic systems. MPs, consisting primarily of polyethylene, polypropylene, and polyacrylamide polymers, have recently been found in 12% of samples of honey collected in Ecuador. Recently, MPs have also been identified in honey bees collected from apiaries in Copenhagen, Denmark, as well as nearby semiurban and rural areas. Given these documented exposures, assessment of their effects is critical for understanding the risks of MP exposure to honey bees. Exposure to polystyrene (PS)-MPs decreased diversity of the honey bee gut microbiota, followed by changes in gene expression related to oxidative damage, detoxification, and immunity. As a result, the aim of this perspective was to investigate whether wide-spread prevalence of MPs might have unintended negative effects on health and fitness of honey bees, as well as to draw the scientific community’s attention to the possible risks of MPs to the fitness of honey bees. Several research questions must be answered before MPs can be considered a potential threat to bees.
Photon–Photon Interactions and the Opacity of the Universe in Gamma Rays
Authors: Franceschini Alberto
Published: May 2021

We discuss the topic of the transparency of the Universe in gamma rays due to extragalactic background light, and its cosmological and physical implications. Rather than a review, this is a personal account on the development of 30 years of this branch of physical science. Extensive analysis of the currently available information appears to us as revealing a global coherence among the astrophysical, cosmological, and fundamental physics data, or, at least, no evident need so far of substantial modification of our present understanding. Deeper data from future experiments will verify to what extent and in which directions this conclusion should be modified.
Angular Distributions of Emitted Electrons in the Two-Neutrino ββ Decay
Authors: Niţescu Ovidiu , Dvornický Rastislav , Stoica Sabin , Šimkovic Fedor
Published: May 2021

The two-neutrino double-beta decay (2νββ-decay) process is attracting more and more attention of the physics community due to its potential to explain nuclear structure aspects of involved atomic nuclei and to constrain new (beyond the Standard model) physics scenarios. Topics of interest are energy and angular distributions of the emitted electrons, which might allow the deduction of valuable information about fundamental properties and interactions of neutrinos once a new generation of the double-beta decay experiments will be realized. These tasks require an improved theoretical description of the 2νββ-decay differential decay rates, which is presented. The dependence of the denominators in nuclear matrix elements on lepton energies is taken into account via the Taylor expansion. Both the Fermi and Gamow-Teller matrix elements are considered. For nuclei of experimental interest, relevant phase-space factors are calculated by using exact Dirac wave functions with finite nuclear size and electron screening. The uncertainty of the angular correlation factor on nuclear structure parameters is discussed. It is emphasized that the effective axial-vector coupling constant gAeff can be determined more reliably by accurately measuring the angular correlation factor.
De Sitter Solutions in Einstein–Gauss–Bonnet Gravity
Authors: Vernov Sergey , Pozdeeva Ekaterina
Published: May 2021

De Sitter solutions play an important role in cosmology because the knowledge of unstable de Sitter solutions can be useful to describe inflation, whereas stable de Sitter solutions are often used in models of late-time acceleration of the Universe. The Einstein–Gauss–Bonnet gravity cosmological models are actively used both as inflationary models and as dark energy models. To modify the Einstein equations one can add a nonlinear function of the Gauss–Bonnet term or a function of the scalar field multiplied on the Gauss–Bonnet term. The effective potential method essentially simplifies the search and stability analysis of de Sitter solutions, because the stable de Sitter solutions correspond to minima of the effective potential.
Minisuperspace Quantization of f(T, B) Cosmology
Authors: Paliathanasis Andronikos
Published: May 2021

We discuss the quantization in the minisuperspace for the generalized fourth-order teleparallel cosmological theory known as fT, B. Specifically we focus on the case where the theory is linear on the torsion scalar, in that consideration we are able to write the cosmological field equations with the use of a scalar field different from the scalar tensor theories, but with the same dynamical constraints as that of scalar tensor theories. We use the minisuperspace description to write for the first time the Wheeler-DeWitt equation. With the use of the theory of similarity transformations we are able to find exact solutions for the Wheeler-DeWitt equations as also to investigate the classical and semiclassical limit in the de Broglie -Bohm representation of quantum mechanics.

Impact of coronavirus pandemic on social processes in Germany
Authors: Nadechdin A. E.
Published: May 2021

Coronavirus restrictions initiated by the German government are not widely approved and supported in the country. Dissatisfaction expressed by certain groups of citizens finds reflection in various protests and acts of violence against representatives of the law enforcement agencies, which are regarded to be the main institutions overseeing adherence to the COVID-19 guidelines. The police have less room for maneuver because of the growing pressure amid the possible spread of nationalist and racist attitudes among the employees. The epidemic increases social and economic tensions, hostility in the society, the number of criminal acts especially in the field of street and financial crime. Apart from the locals, people with a migration background, refugees and in particular representatives of ethnically bound criminal groups commit felonies. The pandemic has an influence on the German foreign politics on a wide range of issues.

ABSTRAK
Pengemasan minyak nabati dan produknya seperti minyak goreng, minyak untuk salad, margarin, dan shortening bertujuan untuk melindungi minyak agar dapat menjangkau konsumen secara aman, sehat, dan tanpa mengurangi kualitasnya. Artikel ini bertujuan untuk mengulas jenis bahan kemasan untuk minyak nabati, aspek perlindungan bahan kemasan terhadap mutu minyak, dan migrasi bahan kemasan ke dalam produk minyak. Bahan kemasan yang umum digunakan untuk mengemas minyak nabati dan produknya adalah kaca, baja, pelat timah, dan bahan plastik seperti polyvinylchloride (PVC), polyethylene terephthalate (PET) dan high density polyethylene (HDPE). Bahan-bahan kemasan tersebut memiliki keunggulan dan kelemahan dalam pengemasan minyak nabati yang tergantung pada fungsinya agar mutu minyak stabil selama distribusi dan penyimpanan. Faktor-faktor yang memengaruhi stabilitas minyak dalam kemasan meliputi faktor internal (komposisi asam lemak dan komponen minor pada minyak nabati) dan faktor eskternal (oksigen, cahaya, suhu, dan waktu penyimpanan). Pemilihan bahan kemasan juga harus mempertimbangkan keamanan minyak dari kontaminan akibat migrasi dari bahan kemasan. Migrasi bahan kemasan dipengaruhi oleh jenis minyak, di mana migrasi total bahan kemasan sedikit lebih tinggi pada minyak yang mengandung asam lemak rantai pendek dan asam lemak tidak jenuh pada jumlah tinggi.

ABSTRACT
The packaging of vegetable oils and their products such as cooking oil, salad oil, margarine, and shortening aims to protect the oil from reaching consumers safely, healthily, and without reducing its quality. This article reviews the packaging materials types for vegetable oils, protection aspects of packaging material to oil quality, and packaging materials migration into oil products. Packaging materials commonly used to package vegetable oils are glass, steel, tin plates, and plastics such as polyvinylchloride (PVC), polyethylene terephthalate (PET), and high-density polyethylene (HDPE). Packaging materials have advantages and disadvantages in the packaging of vegetable oils depend on their functions, so the oil stable during distribution and storage. Factors that influence the package’s oil stability cover internal factors (fatty acid composition and minor components of vegetable oils) and external factors (oxygen, light, temperature, and storage time). Packaging material elections must also consider oil safety from contaminants due to packaging material migration. Packaging materials migration is also influenced by the type of oil, where packaging materials total migration is slightly higher in oils containing short-chain fatty acids and unsaturated fatty acids at high amounts.

Published: May 2021

From 2002 to 2010 twenty-four Dotterel nests were observed on Varangerfjell plateaus near Batsfjord. Females definitely took part in incubation in 18 cases. However, shared incubation could not be ruled out for the remaining 6 nests. One female defended the chicks against her own partner before they left the nest. Another lone female was seen leading 3 chicks for 5 days in a very small section of the study area, to our knowledge the only case of a female with chicks outside the nest ever recorded. Several nests were found less than 100 m apart. One bird laid eggs in the same nest in 2 consecutive years. These findings complement previously published observations and hypotheses.

Comparative analysis of unemployment and inflation in Mexico
Authors: Castro-Valencia Alberto Merced
Published: May 2021

The article examines, based on panel regressions, the long-term relationship between inflation and economic growth based on information for 70 countries and annual data for 1950-2010 The results do not find evidence of a significant trade-off between in ﬂ ation and long-term growth for this sample and period, except if national experiences with average annual in ﬂ ations above the annual 65% threshold are included. That is, outside regimes with persistently very high rates of inflation, there is no systematic or significant inverse relationship between inflation and the growth rate of productive activity. The absence of such long-term trade-off for the aggregate panel is far from implying that for any individual economy the inflation undermines its growth only if it exceeds the 65% per annum The analysis by groups of countries reveals that the value of the threshold of significance is a function of the current monetary regime.

ELDERLY WOMAN IN KARELIAN TRADITIONAL CULTURE: AGE BOUNDARIES AND SOCIOCULTURAL STATUS
Authors: Litvin Yuliya Valer'evna , Minvaleev Sergei Andreevich
Published: May 2021

To a larger extend than in case of a man the transition of a woman from one socio-age status to another in traditional culture was connected with her physiological changes. Stages of growing-up and ageing which were similar in many societies were regulated by the means of local tradition. It included complex of rights and obligations, restrictions and opportunities, which were determined by a combination of climatic, socioeconomic, cultural, religious, ethnic and other factors. The focus of the paper is to identify the universal and the ethnically specific traits in the scenarios of women aging in Karelian culture. Research purposes included consideration of issues about the old age limits, the field of female socio- age stratification terminology, the matter of sociocultural status, limitations and opportunities for Karelian women within and outside the family. The study observes the period of the late XIX - early XX century. The territorial framework is outlined by the boundaries of the Karelian population dwelling in the Olonets and Arkhangelsk provinces (the part of the Republic of Karelia in present). The authors conclude that late maturity was an important milestone in the life of Karelian woman. Normative role was growing, hierarchical relations in the family were redefined. However, the life of an elderly woman was not limited to family affairs. Participation in life cycle ceremonies, religious and missionary activities was a symbolic resource of the Karelian women in rural society and could be converted into revenue.

Authors: Popova Elena Vasilyevna
Published: May 2021

The article deals with different types of pasta products for soups in traditional Udmurt and Beserman cuisine, their local names, composition, cooking technologies, and area of distribution. Soups with pieces of yeast dough or fresh dough are included in the menu of national cuisine and have an important symbolic place in food identity. Such soups were prepared as an everyday dish, or as a ritual dish with sacrificial animal (poultry) meat; some types of dishes are preserved in the wedding ritual of the Southern Udmurts. Soups with slices of dough are more common in presentations and master classes of Beserman and Udmurt food traditions. In traditional cuisine flour of spelt , buckwheat, peas, oats, rye, wheat and mixtures of different kinds of flour were used. In modern cuisine, they are mainly made of wheat flour. Today traditional pasta products are often replaced by industrial ones like macaroni, noodles and spaghetti, but some traditional pasta products are still popular. The research is based on written sources, dictionaries, folklore texts, description of local cuisine and the author’s field materials.

Authors: Rodionova Aleksandra Pavlovna
Published: May 2021

The article provides a brief historical background on the most significant sources written in the Karelian language, as well as a description of the Ludic dialect and the peculiarities of the Svyatozersk dialect, which served as the basis of the first dictionary. The activities of the translation commission in the 19th century resulted in the first translations of the Gospel and other liturgical literature, and at the same time dictionaries, grammars and primers were written in 50 languages of Russia. The Russian-Karelian Dictionary was published in St. Petersburg in 1908. The compiler of the dictionary was a teacher of the Svyatozersk School, Mikhail Dmitrievich Georgievsky. The dictionary includes 1523 words: the dictionary entries in the source are followed by appendices containing vocabulary on specific topics: names, days of the week, holidays; the dictionary also contains numerals, verb conjugations, sentences with translation.The value of the dictionary, published more than a hundred years ago, lies in the fact that it reflects the vocabulary characteristic of the Svyatozersky dialect, chosen as one of the basic dialects in the lemmatization of the Ludic subcorpus (VepKar).

Tratamiento del ilícito publicitario desleal concurrencial en España
Authors: Bernad Monferrer Estela
Published: May 2021

La competencia económica es un presupuesto de la actividad de comercio, derivado del principio constitucional de libertad de empresa recogido en el art. 38 de la CE. La libertad de empresa presupone la libertad de competencia, con sus consecuentes limitaciones, producidas por las propias deficiencias de los mecanismos de mercado, que darán como resultado que la competencia que se desarrolla en el mismo sea una competencia imperfecta.
Investigación/research la perspectiva. Del renacimiento al 3-D
Authors: Castillo-Pomeda José-María , Ortiz Sobrino Miguel Ángel

El concepto de perspectiva nos es hoy tan familiar que incluso lo empleamos en el lenguaje coloquial o periodístico, a veces sin demasiada fortuna. Todos sabemos que perspectiva es el “punto de vista”, la profundidad, la lejanía… Sin olvidar que la “perspectiva aérea” no es ver el paisaje desde un avión…
La creación de empleo, misión -y visión- de emprendedores solidarios
Authors: Macías Antonio
Published: May 2021

Las nuevas realidades económicas y de producción nos están despertando de un sueño vivido durante la segunda mitad del siglo pasado en el que las estructuras empresariales y de gestión, los derechos y beneficios logrados para los trabajadores, las vinculaciones entre empresa-trabajador-producto se empiezan a romper como consecuencia de la irrupción en nuestras vidas de las nuevas tecnologías al servicio de todas las personas. Sin embargo y pese a la simplificación de trámites y gestiones que dichas tecnologías pueden suponer, en España no se termina de ver esa ventaja, al contrario que en otros países de nuestro entorno, sobre todo en el ámbito de los que se deciden a iniciar una nueva actividad empresarial. Al contrario, la implantación de éstas en las empresas privadas está facilitando una nueva forma de trabajo: el tele-trabajo. La conexión instantánea con cualquier y desde cualquier punto a una central o con un cliente, se encuentren donde se encuentren empresa y/o cliente o proveedor, va a suponer un cambio en las estructuras empresariales que puede beneficiar a muchos, acercando, promoviendo y facilitando el comercio y la gestión en las empresas, al eliminar viejas estructuras de costes elevados. Pero como siempre, cuando se modifican estructuras, se generará un coste social y personal que no puede ser obviado.
Comprensión y explicación del discurso publicitario

En las Investigaciones lógicas, Husserl (1859-1938) trata de hallar un método alternativo al psicologismo, el cual queda encerrado en el marco de un positivismo. En el momento en el que Husserl se plantea su investigación, el psicologismo consistía en hacerse una cierta composición de lugar llena de sentido común, con una apariencia de inteligibilidad inmediata.
Modelo curricular por proyectos: diseño de los ciclos propedéuticos en la Universidad Colombiana
Authors: Adonaí Vera Silva Alhim
Published: May 2021

El modelo curricular por proyectos (MCP) que se propone para el diseño de los ciclos propedéuticos en la universidad colombiana2 podría sintetizarse en cuatro palabras: Necesidades, Problemas, Potencialidades y Proyectos. (NPPP). El modelo curricular tradicional se caracteriza por una agrupación, por lo regular aleatoria, de conocimientos de una disciplina, que a la vez puede subfragmentarse, con símbolos como: I, II, III, IV… estos fragmentos, trozos o pedazos, o asteroides de conocimientos flotan inconexos, desarticulados o abandonados en la mente del estudiante (memoria), esperando una oportunidad para demostrar su capacidad de resolver problemas complejos de sí mismo, la familia, la comunidad, la biodiversidad y del planeta interconectado en la globalidad.
El Silencio del art brut: una visión diferente de un arte conectada a la vida
Authors: Mateo Sánchez Cecilia , Mengual Luna Isabel
Published: May 2021

Durante los últimos 60 años, el panorama artístico ha sufrido más cambios que a lo largo de toda su historia. Las vanguardias de la Modernidad dejaron claro testimonio de ruptura respecto al arte predecesor, tanto en su forma como en su contenido. Al final de la Modernidad todavía podía hablarse de disciplinas como pintura, escultura, grabado o dibujo, aun con sentido, desde hace 60 años se habla de otras prácticas tales como, instalación, performance, body art, land art, video art o art brut, etc., sin que estas puedan ser incluidas en los grandes géneros de las artes conocidos por todos. La enorme cantidad de innovaciones ocurridas en el campo del arte desde la Segunda Guerra Mundial nos obliga por lo tanto, a denominar este nuevo periodo de una forma distinta al de modernidad, denominándolo entonces: postmodernidad. Es en este contexto, donde situamos el arte bruto o art brut, arte marginal u outsider art y la independencia que estas prácticas poseen de lo que actualmente se entiende por aprendizaje artístico. Surge así, la necesidad de una nueva crítica y una nueva historiografía para entender, analizar y juzgar, estas nuevas formas y mecanismos de producir, que nos conduzcan al entendimiento del arte postmoderno. Nos plantearemos entonces si hay detrás de ellas un aprendizaje artístico, tal como lo entendemos hoy y si estas contribuyen al desarrollo social de personas con capacidades diversas.
