Understanding the anthropogenic and natural factors that affect runoff water quality is essential for proper planning of water protection and forest management, particularly in the changing climate. We measured water quality and runoff from 10 unmanaged and 20 managed forested headwater catchments (7–12,149 ha) located in Finland. We used linear mixed effect models to test whether the differences in total organic carbon (TOC), total nitrogen (TN) and total phosphorus (TP) export and concentrations observed can be explained by catchment characteristics, land use, forest management, soil fertility, tree volume and hydrometeorological variables. Results show that much of variation in TOC, TN and TP concentrations and export was explained by drainage, temperature sum, peatland percentage and the proportion of arable area in the catchment. These models explained 45–63% of variation in concentrations and exports. Mean annual TOC export in unmanaged catchments was 56.4 ± 9.6 kg ha−1 a−1, while in managed it was 79.3 ± 3.3 kg ha−1 a−1. Same values for TN export were 1.43 ± 0.2 kg ha−1 a−1 and 2.31 ± 0.2 kg ha−1 a−1, while TP export was 0.053 ± 0.009 kg ha−1 a−1 and 0.095 ± 0.008 kg ha−1 a−1 for unmanaged and managed, respectively. Corresponding values for concentrations were: TOC 17.7 ± 2.1 mg L−1 and 28.7 ± 1.6 mg L−1, for TN 420 ± 45 µg L−1 and 825 ± 51 µg L−1 and TP 15.3 ± 2.3 µg L−1 and 35.6 ± 3.3 µg L−1. Overall concentrations and exports were significantly higher in managed than in unmanaged catchments. Long term temperature sum had an increasing effect on all concentrations and exports, indicating that climate warming may set new challenges to controlling nutrient loads from catchment areas.
Environmental Drivers of Macroinvertebrate Assemblages within Peat Pool Habitat-Implication for Bioassessment
Authors: Tarkowska-Kukuryk Monika
Published: September 2021

Macroinvertebrates are a crucial component of wetland trophic webs. Many taxa are used as bioindicators of ecosystem change. However, relationships between macroinvertebrates and the environmental factors in peat pool habitats are still not well recognized. The present study shows the results of long-term studies during the years 2010–2020, on the responses of macroinvertebrates to the changes of environmental variables in a peat pool habitat formed as a result of peat exploitation on continental raised bog. The RDA analysis significantly explained 87.3% of the variance in macroinvertebrates abundances. Assemblages of most taxa (Anisoptera, Chironomidae, Ceratopogonidae, Coleoptera, Hydrachnidia and Tabanidae) showed a strong relationship with N-NO3 and pH. Moreover, densities of Chaoboridae larvae were explained by chlorophyll-a concentrations. Dominant taxon, Chironomidae, constituted from 48% to 87% of total faunal density. The highest proportions showed larvae of Psectrocladius sp. (gr. sordidellus) and Chironomus sp. Changes in the composition of macroinvertebrate fauna over a period of 10 years reflect the eutrophication process of the peat pool and deterioration of habitat conditions.

Published: September 2021

Seasonal water-level fluctuations may lead to changes in river nutrients, which causes corresponding changes in the trophic structure of an aquatic food web, and finally affects the whole ecosystem. In this study, we focused on the Ganjing River, a tributary of the Yangtze River, China. Common organisms were sampled and measured for carbon and nitrogen stable isotopes in the wet and dry seasons, respectively, and the relative contributions of different food sources were combined to construct the food web, so as to realize the influence of water-level fluctuation on aquatic food web. Our results showed that basal food sources for fish consumers were endogenous carbon sources such as POM, zooplankton and zoobenthos in the dry season, while high water level exposed fish to more diverse and abundant food sources, and the contribution proportions of exogenous carbon sources (e.g., terrestrial detritus) to consumers increased in the wet season. In parallel, the abundance and species diversity of fish were higher than those in the dry season. Most fish species had relatively higher trophic levels in the dry season compared to the wet season, because the increase in fish densities led to an increase in piscivores fish. The food web was composed of planktonic and benthic food chains in the dry season. During the wet season, the planktonic food chain was dominant, followed by the herbivorous food chain, and the benthic food chain was relatively less important. Therefore, water-level fluctuation may alter the trophic linkages within fish communities, which contributed to a more complex and interconnected food web. Moreover, as we expect, the stable isotope analysis food web was broadly in line with the gut content analysis food web.

Published: September 2021

In China, where some regions are over-reliant on groundwater, groundwater consumption is faster than replenishment, which results in a continuous decrease in the groundwater level. Here, we applied spatial and temporal methods to analyze the spatiotemporal variations in groundwater in China from GRACE, GRACE-FO, and GLDAS data. From a national perspective, groundwater storage showed a decreasing trend in northern China and an increasing trend in southern China. The results showed that the rates of groundwater depletion in North China, the Loess Plateau, and Northwest China were −10.09 ± 0.94, −10.05 ± 1.05, and –4.91 ± 0.28 mm y−1 equivalent height of water from 2003 to 2019, respectively. Furthermore, the groundwater in South China, the middle-lower Yangtze River, and the Ch-Yu region had a positive trend, with rates of 7.26 ± 1.51, 7.73 ± 1.35, and 3.61 ± 0.53 mm y−1 equivalent height of water, respectively. We also found that groundwater storage fluctuated slightly before 2016 on the Qinhai-Tibet Plateau and in Northeast China and decreased significantly after 2016. The Yun-Gui Plateau had a fluctuating trend. Investigating the spatiotemporal variation in groundwater storage in China can provide data for initiating regional ecological and environmental protection.
Two Mechanisms of Earthquake-Induced Hydrochemical Variations in an Observation Well
Authors: Zhou Zhihua , Zhong Jun , Zhao Jing , Yan Rui , Tian Lei , Fu Hong
Published: September 2021

Due to frequent large earthquakes in the Lanping-Simao fault basin—located in China’s Yunnan Province—the Simao observation well has observed groundwater discharge, as well as Ca2+, Mg2+, and HCO3− concentrations every day between 2001–2018. Over 18 years of observations, M ≥ 5.6 earthquakes within a radius of 380 km from the well were seen to cause hydrochemical variations. In this study, we investigated CO2 release and groundwater mixing as possible causes of regional earthquake precursors, which were caused by the characteristics of the regional structure, lithology, water-rock reactions, and a GPS velocity field. Precursory signals due to CO2 injection are normally short-term changes that take two months. However, groundwater mixing linked to earthquakes was found to take, at the earliest, 15 months. The proportion of shallow water that contributes to mixing was found to significantly increase gradually with the stronger regional strain. These finding delineate the two mechanisms of earthquake-induced hydrochemical variations in an observation well, and would contribute to a better understanding of chemical changes before events in the Simao basin.
Anomaly Detection in Dam Behaviour with Machine Learning Classification Models
Authors: Salazar Fernando , Conde André , Irazábal Joaquín , Vicente David J.
Published: September 2021

Dam safety assessment is typically made by comparison between the outcome of some predictive model and measured monitoring data. This is done separately for each response variable, and the results are later interpreted before decision making. In this work, three approaches based on machine learning classifiers are evaluated for the joint analysis of a set of monitoring variables: multi-class, two-class and one-class classification. Support vector machines are applied to all prediction tasks, and random forest is also used for multi-class and two-class. The results show high accuracy for multi-class classification, although the approach has limitations for practical use. The performance in two-class classification is strongly dependent on the features of the anomalies to detect and their similarity to those used for model fitting. The one-class classification model based on support vector machines showed high prediction accuracy, while avoiding the need for correctly selecting and modelling the potential anomalies. A criterion for anomaly detection based on model predictions is defined, which results in a decrease in the misclassification rate. The possibilities and limitations of all three approaches for practical use are discussed.
Prediction of Surface Water Quality by Artificial Neural Network Model Using Probabilistic Weather Forecasting
Authors: Jung Woo Suk , Kim Sung Eun , Kim Young Do
Published: September 2021

We developed an artificial neural network (ANN)-based water quality prediction model and evaluated the applicability of the model using regional probability forecasts provided by the Korea Meteorological Administration as the input data of the model. The ANN-based water quality prediction model was constructed by reflecting the actual meteorological observation data and the water quality factors classified using an exploratory factor analysis (EFA) for each unit watershed in Nam River. To apply spatial refinement of meteorological factors for each unit watershed, we used the data of the Sancheong meteorological station for Namgang A and B, and the data of the Jinju meteorological station for Namgang C, D, and E. The predicted water quality variables were dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), total organic carbon (TOC), total phosphorus (T-P), and suspended solids (SS). The ANN evaluation results reveal that the Namgang E unit watershed has a higher model accuracy than the other unit watersheds. Furthermore, compared with Namgang C and D, Namgang E has a high correlation with water quality due to meteorological effects. The results of this study will help establish a water quality forecasting system based on probabilistic weather forecasting in the long term.

Published: September 2021

The Podu Iloaiei Dam Lake located on the Bahluet River from Bahlui hydrographic basin, north-eastern Romania, is one of the most important water resources used for aquaculture activities in the region of interest. In the present study, the chemical composition related to water-soluble ions and elements was assessed in both water and sediment samples collected from the area of interest during July 2017 and October 2017, representative months for warm and cold seasons, respectively. Water-soluble ions (H3C2O2−, HCO2−, C2O42−, F−, Cl−, NO2−, Br−, NO3−, SO42−, Li+, Na+, NH4+, K+, and Ca2+) were analyzed by ion chromatography, while inductively coupled plasma mass spectrometry was used to quantify water-soluble fractions of elements (Be, B, Mg, Al, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, Rb, Sr, Mo, Ru, Pd, Ag, Cd, Sn, Sb, Te, Ba, Ir, Tl, Pb, Bi, and U). Evidence was obtained on the contributions of both anthropogenic and natural (pedologic) related sources in controlling the chemical composition of the water and sediment samples in the area. Analysis of Piper diagrams revealed the existence of CO32−/HCO3− and Ca2+/Mg2+ as dominant species for the sediment samples. The interest water pool was found to be oligotrophic over the warm period and eutrophic over the cold period. Overall, abundances and the association of chemical species in the area seemed to be controlled by a complex interplay between the water body’s main characteristics, meteorological factors, and anthropogenic activities. Moreover, the present results suggest that precautions should be taken for physicochemical parameter monitoring and prevention acts for surface water quality assurance in order to control the potential negative influence of some chemical parameters on fish productivity. Reported data also have a high potential to be used by experts in the field of developing lake water management policies for a sustainable exploitation of various aquatic systems.
Hydrogeological Investigation for the Assessment of Spring Pollution Due to Abandoned Mines in a Karst Area
Authors: Ren Hujun , Sui Wanghua , Meng Xiangdong , Guo Rui
Published: September 2021

This paper presents a hydrogeological investigation case study for assessing the sources and pathways of spring pollution in a karst area in Guizhou Province, Southern China. Our methods included hydrogeological surveys, geophysical surveys, cave detection, tracer tests, and borehole drilling. The results showed that the pollution of the Longdong Spring is controlled by the amount of rainfall, which also determines the duration of pollution. The concentration of Fe and Mn ions in the spring was found to exceed that in the code for drinking water quality (China) by more than 300 times. The investigations showed that the source of the pollution is the mine water drainage from the abandoned Feilong coal mine, which is located to the northwest of the Longdong Spring. The drainage to the spring was found to occur 24 h after the groundwater level in the goaf reached approximately +908 m above sea level. This indicates a recharge pathway between the abandoned mine and the Longdong Spring. Recommendations for grouting around the spring and sinkhole for pollution control are put forth.
Hydrochemical Characteristics and Evolution of Groundwater in the Alluvial Plain (Anqing Section) of the Lower Yangtze River Basin: Multivariate Statistical and Inversion Model Analyses

Published: September 2021

The alluvial plain (Anqing section) of the lower reaches of the Yangtze River basin is facing increasing groundwater pollution, not only threatening the safety of drinking water for local residents and the sustainable development and utilization of groundwater resources but also the ecological security of the Yangtze River Basin. Therefore, it is necessary to conduct a preliminary analysis on the hydrochemical characteristics and evolution law of groundwater in this area. This study aimed to evaluate potential hydrogeochemical processes affecting the groundwater quality of this area by analyzing major ions in groundwater samples collected in 2019. Compositional relationships were determined to assess the origin of solutes and confirm the predominant hydrogeochemical processes controlling various ions in groundwater. Moreover, factors influencing groundwater quality were evaluated through the factor analysis method, and the control range of each influencing factor was analyzed using the distribution characteristics of factor scores. Finally, reverse hydrogeochemical simulation was carried out on typical profiles to quantitatively analyze the hydrochemical evolution process along flow paths. The Piper trilinear diagram revealed two prevalent hydrochemical facies, Ca-HCO3 type (phreatic water) and Ca-Na-HCO3 type (confined water) water. Based on the compositional relationships, the ions could be attributed to leaching (dissolution of rock salt, carbonate, and sulfate), evaporation and condensation, and cation exchange. Four influencing factors of phreatic water and confined water were extracted. The results of this study are expected to help understand the hydrochemical characteristics and evolution law of groundwater in the alluvial plain (Anqing section) of the lower Yangtze River basin for effective management and utilization of groundwater resources, and provide basic support for the ecological restoration of the Yangtze River Basin.
Large-Scale Water Storage in Aquifers: Enhancing Qatar’s Groundwater Resources
Authors: Jacob Damien , Ackerer Philippe , Baalousha Husam Musa , Delay Frederick
Published: September 2021

Qatar’s water resource has been largely overexploited, leading to the severe depletion of its aquifers and degradation of water quality due to saline intrusions. Qatar envisions employing regional aquifers to store water via forced injection of desalinated water and thus increase available from a few days to two months. A strategy for the implementation of forced injections is proposed based on a spatially distributed model of groundwater flow at the scale of the whole country. The model is based on calibration under steady-state flow conditions and for a two-dimensional single regional aquifer due to the lack of data. Injection scenarios include various mean injection rates at the scale of the whole system and are interpreted under the assumption that the additional storage should feed 2.7 M inhabitants for two months at a rate of 100 L/person/day. When this water supply stock is reached, the model is run to define the infiltration rate, which allows the stock to remain constant over time as a result of an even balance between infiltrations, withdrawals and also leaks or inlets through the boundary conditions of the system.

Published: September 2021

Background

Many patients with heart failure with preserved ejection fraction (HFpEF) are undiagnosed, and UK general practice registers do not typically record heart failure (HF) subtype. Improvements in management of HFpEF is dependent on improved identification and characterisation of patients in primary care.

Aim

To describe a cohort of patients recruited from primary care with suspected HFpEF and compare patients in whom HFpEF was confirmed and refuted.

Design & setting

Baseline data from a longitudinal cohort study of patients with suspected HFpEF recruited from primary care in two areas of England.

Method

A screening algorithm and review were used to find patients on HF registers without a record of reduced ejection fraction (EF). Baseline evaluation included cardiac, mental and physical function, clinical characteristics, and patient reported outcomes. Confirmation of HFpEF was clinically adjudicated by a cardiologist.

Results

In total, 93 (61%) of 152 patients were confirmed HFpEF. The mean age of patients with HFpEF was 79 years, 46% were female, 80% had hypertension, and 37% took ≥10 medications. Patients with HFpEF were more likely to be obese, pre-frail or frail, report more dyspnoea and fatigue, were more functionally impaired, and less active than patients in whom HFpEF was refuted. Few had attended cardiac rehabilitation.

Conclusion

Patients with confirmed HFpEF had frequent multimorbidity, functional impairment, frailty, and polypharmacy. Although comorbid conditions were similar between people with and without HFpEF, the former had more obesity, symptoms, and worse physical function. These findings highlight the potential to optimise wellbeing through comorbidity management, medication rationalisation, rehabilitation, and supported self-management.
Postnatal depression: identification of risk factors in the short-stay maternity program in Belgium. A cross-sectional study
Authors: Lelièvre Julie , Hompes Titia , Schoenmakers Birgitte
Published: September 2021

Background

Postnatal depression (PND) is one of the most frequent complications in women of childbearing age in the developed world. The onset of PND is influenced by several risk factors. In an attempt to avoid unnecessary long maternity stays, the Short Stay Maternity programme was launched, shifting care from the hospital environment to the outpatient setting.

Aim

In order to develop an efficient programme to trace vulnerable women after childbirth and to provide support within primary care, the aim was to create an inventory of the risk factors for PND within the population of women participating in the short-stay programme.

Design & setting

This study is a cross-sectional study without follow-up. Women in Belgium were invited by email to participate in the Short Stay Maternity programme within 3 months of delivery.

Method

The questionnaire addressed background features and feelings during the maternity period, supplemented with the validated Dutch version of the Edinburgh Postnatal Depression Scale (EPDS). The primary outcome measure of the questionnaire was the score on the EPDS.

Results

A total of 131 (27.46%) of the invited women participated. Sixteen participants (12.21%) presented with a positive score on the EPDS. The odds ratio (OR) for a positive score on the EPDS when experiencing negative feelings was 13.5 (95% confidence interval [CI] = 4.14 to 44.01). If only material support was provided, the OR for a positive EPDS score was OR 11.2 (95% CI = 2.72 to 55.5).

Conclusion

In this study, two risk factors were identified for PND: negative feelings during pregnancy and the provision of only material support by the partner.

An Encoder-decoder Deep Learning Model Combining Mixed Attention Mechanism and Asymmetric Convolution for Automation of Retinal Vessels Segmentation
Authors: Cao Jiajia , Zhou Qin , Chen Yi , Yin Lin , Zhang Fei
Published: September 2021

The segmentation of the retinal vascular tree is the fundamental step for diagnosing ophthalmological diseases and cardiovascular diseases. Most existing vessel segmentation methods based on deep learning give the learned features equal importance. Ignored the highly imbalanced ratio between background and vessels (the majority of vessel pixels belong to the background), the learned features would be dominantly guided by background, and relatively little influence comes from vessels, often leading to low model sensitivity and prediction accuracy. The reduction of model size is also a challenge. We propose a mixed attention mechanism and asymmetric convolution encoder-decoder structure(MAAC) for segmentation in Retinal Vessels to solve these problems. In MAAC, the mixed attention is designed to emphasize the valid features and suppress the invalid features. It not only identifies information that helps retinal vessels recognition but also locates the position of the vessel. All square convolutions are replaced by asymmetric convolutions because it is more robust to rotational distortions and small convolutions are more suitable for extracting vessel features (based on the thin characteristics of vessels). The employment of asymmetric convolution reduces model parameters and improve the recognition of thin vessel. The experiments on public datasets DRIVE, STARE, and CHASE\_DB1 demonstrated that the proposed MAAC could more accurately segment vessels with a global AUC of 98.17$\%$, 98.67$\%$, and 98.53$\%$, respectively. The mixed attention proposed in this study can be applied to other deep learning models for performance improvement without changing the network architectures.
Overcoming Data Availability Attacks in Blockchain Systems: LDPC Code Design for Coded Merkle Tree
Authors: Mitra Debarnab , Tauz Lev , Dolecek Lara
Published: September 2021

Light nodes in blockchains improve the scalability of the system by storing a small portion of the blockchain ledger. In certain blockchains, light nodes are vulnerable to a data availability (DA) attack where a malicious node makes the light nodes accept an invalid block by hiding the invalid portion of the block from the nodes in the system. Recently, a technique based on LDPC codes called Coded Merkle Tree (CMT) was proposed by Yu et al. that enables light nodes to detect a DA attack by randomly requesting/sampling portions of the block from the malicious node. However, light nodes fail to detect a DA attack with high probability if a malicious node hides a small stopping set of the LDPC code. To mitigate this problem, Yu et al. used random LDPC codes that achieve large minimum stopping set size with high probability. Although effective, these codes are not necessarily optimal for this application, especially at short code lengths, which are relevant for low latency systems, IoT blockchains, etc.. In this paper, we focus on short code lengths and demonstrate that a suitable co-design of specialized LDPC codes and the light node sampling strategy can improve the probability of detection of DA attacks. We consider different adversary models based on their computational capabilities of finding stopping sets in LDPC codes. For a weak adversary model, we devise a new LDPC code construction termed as the entropy-constrained PEG (EC-PEG) algorithm which concentrates stopping sets to a small group of variable nodes. We demonstrate that the EC-PEG algorithm coupled with a greedy sampling strategy improves the probability of detection of DA attacks. For stronger adversary models, we provide a co-design of a sampling strategy called linear-programming-sampling (LP- sampling) and an LDPC code construction called linear-programming-constrained PEG (LC-PEG) algorithm. The new co-design demonstrates a higher probability of detection of DA attacks compared to approaches in earlier literature.

Avaliação em educação física escolar: novos ou velhos parâmetros?
Authors: Souza Iris Reis , Resende Moisés Sipriano
Published: September 2021

INTRODUÇÃO: Tradicionalmente a avaliação escolar tem se caracterizado pela classificação, inclusão e a exclusão de educandos do sistema educacional. Educadores progressistas têm sugerido repensar a avaliação como uma prática contínua de coleta de informações sobre o processo de ensino e aprendizagem que visa contribuir com a formação do educando. Em se tratando da Educação Física, disciplina historicamente marcada pelo paradigma da aptidão física e do treinamento esportivo, a avaliação tem recebido novas ideias, no sentido de ampliar a análise da aprendizagem, para além da dimensão motora. Entretanto, pesquisas indicam poucas mudanças no cenário avaliativo da Educação Física escolar. OBJETIVO: Identificar concepções e práticas avaliativas de professores de Educação Física que lecionam em escolas no Estado de Goiás. MÉTODOS: : Foi realizada uma pesquisa qualitativa. Para a coleta de dados foi utilizado um questionário elaborado em plataforma eletrônica. O instrumento foi encaminhado para 54 professores de Educação Física que integram a rede de contatos pessoais dos autores. Deste total, 22 professores responderam o questionário. Os dados obtidos foram analisados seguindo a metodologia de análise de conteúdo. RESULTADOS: Foi possível observar que há maior preocupação dos professores em avaliar a aprendizagem cognitiva, bem como o desenvolvimento integral do educando em detrimento da dimensão física, o que demonstra certa aproximação com as novas teorias da avaliação. Ao mesmo tempo, verificou-se que quase todos os docentes avaliam a participação, demonstrando que esta prática continua frequente. CONCLUSÃO: Conclui-se que há avanços nas concepções e práticas dos professores visando a avaliação formativa. Entretanto, romper com a tradição de se avaliar a participação e a política somatória das escolas ainda representa um desafio.
THE IMPACT OF CONCEPT MAPPING AS A TEACHING STRATEGY ON THE STUDENTS’ ACHIEVEMENT AND INTEREST IN ENGLISH
Authors: Mr. Rommel P. Manzon
Published: September 2021

The purpose of this study is to determine the impact of concept mapping as a teaching strategy on the students’ achievement and interest in English. It is a quasi-experimental design of non- equivalent pre-test post-test control group is used. Stratified random sampling technique is adapted in selecting the 250 students from the different schools in the Philippines. Two research instruments is developed by the researchers and used for data collection are: Students’ English Achievement Test (STAT) and Students’ Interest Inventory (SII). Mean and Standard Deviation are used to answer the three research questions, while three hypotheses are tested at 0.05 error margins using the t-test analysis. The result of the findings showed that there is significant difference in the mean achievement scores and interest rating of students are exposed to concept mapping strategy in English. There is a significant impact on the gender of the respondents on achievement of students that are exposed to concept mapping strategy. The researchers recommended among other things: the integration of concept mapping strategy in the curriculum, adequate training of English teachers on the use of concept mapping strategy.
KEYWORDS: concept mapping; achievement; interest; gender; teaching strategy; and interest in English
Incidir en la educación
Authors: Torres Rosa María
Published: September 2021

El artículo analiza la incidencia política como herramienta eficaz para la participación de la sociedad civil en la implementación de políticas públicas, analizándola en particular en la educación. Postula cómo entender esa incidencia y se pregunta quiénes deben incidir. Afirma que la incidencia en las políticas educativas no tiene a la fecha demasiados casos exitosos que contar, y que una agenda amplia y renovada como la propuesta aquí, pensada desde la complejidad del cambio educativo, implicaría aportes importantes en los modos de pensar y hacer incidencia política en pro del derecho a la educación.
Los jóvenes y la comtemplación del arte
Authors: Revilla Federico
Published: September 2021

En este trabajo se trazan las que pudieran ser ''líneas generales'' de la contemplación del arte, aspecto quizá ''no siempre'' tenido en cuenta para una educación integral de la juventud. Partiendo de la convicción de que la educación no es sólo ''aprendizaje de conocimientos'', se deduce que debiera abarcar también aspectos sólo en apariencia marginales, donde se integran el disfrute de la vida, la capacidad de selección y de discernimiento, el entusiasmo, el descubrimiento, así como la autonomía de cacla individuo frente a los nuevos estímulos. Entre éstos, el arte es una faceta más de la vida que contribuye a la felicidad y a la seguridad de los individuos: rescatándoles, en cierto modo, del crudo utilitarismo que reseca y aburre los espíritus.
La ciudad de los libros
Authors: Ospina William
Published: September 2021

Este sugestivo texto, producto de una conferencia· magistral que el escritor William Ospina ofreció el lunes 16 de abril de 2007, en el marco de ''Cátedra de Pedagogía'' y''Bogotá capital mundial del libro'', maravilla por diversas razones; quizás la más clave sea el rescatar al lector como autor. Para ello hace un paseo por textos, lugares y obras de la tradición literaria que le permiten mostrar cómo en ese circuito de texto-lectorautor(es) las palabras cumplen a cabalidad su oficio: a la vez que las generamos ellas nos crean, recrean y conducen una tras otra por reinos no imaginados, más allá o más acá de las seductoras imágenes de ésta época con su intento por agotar el sentido y a los lectores.
La sonrisa lúcida y enigmatica de la ciudad ludica
Authors: Alvarez Escobar Lván Daría
Published: September 2021

El ensayo ''La sonrisa lucida y enigmática de la ciudad Lúdica'' es un alegato a favor de los niños y las niñas, del juego en sus múltiples facetas, como espacio de conocimiento libre y espontaneo para el desarrollo del cuerpo, el lenguaje, la mente y la imaginación de los infantes. Es un intento por devolverle al juego un espacio de libertad en la ciudad del cual se le ha ido despojarndo al niño por un culto desmedido al progreso y el trabajo en nuestra actual cultura adulta. Cifra sus esperanzas en una arquitectura nueva y utópica que reivindique de la mano del Estado los espacios del juego en los colegios, los espacios verdes y al aire libre, en donde la imaginación lúdica se cultive como espacio libre y socializador del conocimiento.
El sistema educativo:viejos retos,nuevos desafíos
Authors: Puello-Socarrá José Francisco
Published: September 2021

L os vínculos entre Política, Política Educativa y el concepto de Educación son cruciales para descifrar el actual panorama de la Educación en Colombia. Este artículo intenta vincular estos tópicos, haciendo énfasis en la calidad educativa. Muestra en qué sentido las lógicas globales y las dinámicas locales que influyen en los diseños de política educativa han tenido efectos negativos. Se exponen algunas variables que inciden en la calidad educativa, insistiendo, en que los objetivos en términos de calidad deben considerar la situación de los docentes, pivote fundamental para mejorar el escenario. Igualmente, se describen los posibles efectos del Tratado de Libre Comercio entre Colombia TLC y los Estados Unidos en términos educativos y una agenda propositiva que eventualmente sirva como punto de referencia para enfrentar los principales desafíos. El artículo expone cómo a pesar de que diversos estudios han llamado la atención sobre el tema educativo, en particular, frente a los problemas de calidad de la educación, aconsejando un cambio sustancial en las políticas y una transformación estructural del sistema educativo,se insiste en mantener la actual política de educación gubernamental.
