Justificaciones extra-literarias del cuento en la enseñanza primaria
Authors: Bustamante Zamudio Guillermo 
Published: August 2017

Antes de la Renovación curricular, en las Guías para el maestro que el Ministerio de Educación Nacional entregaba a los docentes, se justificaba la literatura en la enseñanza primaria de dos maneras. No obstante, ambas formas remiten la literatura a aspectos exteriores a ella misma: de un lado, a asuntos distantes de su especificidad artística (tales como apoyar los contenidos de otras asignaturas, despertar sentimientos patrióticos y formar moralmente); y, de otro lado, a asuntos que si bien apuntan a su especificidad (tales como la materialidad lingüística de la literatura y la pregunta por el efecto estético), no obstante, son planteados de una manera que la escamoten
1er Congreso latinoamericano de investigación cualitativa
Authors: Díaz Gómez Álvaro 
Published: August 2017

Presentar la reseña de un libro es colocar en común una perspectiva de entendimiento de un texto, desde una lectura que se hace y que está cargada de intencionalidades e intereses; pero hacer esta reseña de las memorias de un Congreso obliga a que de manera deliberada se hagan agrupaciones temáticas, acercamientos de opiniones, entrelazamientos de conceptos que pueden guardar relación y ser síntesis de la diversas voces que se pronuncian a través de los párrafos del texto.

Published: August 2017

Introduction: Flexible flatfoot is common amongst children, although treatment is rarely indicated. The calcaneo-stop procedure has been reported to be effective in short-term studies. We aim to evaluate the long-term outcomes of the calcaneo-stop procedure in the treatment of flexible flatfoot in children.Material and Methods: Twenty-six calcaneo-stop procedures performed between 1995 and 2006 on 13 patients were evaluated clinically and using photopodoscopy, and the FAOS questionnaire was applied for both feet.Results: Of the 26 feet evaluated, 22 presented with heel valgus, 13 had forefoot supination and 11 had abnormal footprints. Median FAOS questionnaire score was 97.22 for ‘Pain’, 92.86 for ‘Other symptoms’, 98.53 for ‘Function in daily living’, 100 for ‘Function in sports and recreation’ and 93.75 for ‘Foot and ankle-related quality of life’.Discussion: The calcaneo-stop procedure is the least invasive and most simple surgical treatment for symptomatic flexible flatfoot in children. Short-term studies report excellent clinical and radiographic results. The authors report alterations in clinical parameters in a large proportion of patients. These findings can be due to biomechanical alterations in the years following removal of the screw. Patient foot and ankle-related satisfaction data is promising, although hard to evaluate given the absence of preoperative data.Conclusion: Larger, prospective, controlled studies are required to better evaluate the long-term success of this procedure.

Published: August 2017

There is a limited understanding of solute transport properties of degraded peat soils as compared to mineral substrates. A lower organic matter (OM) content is often the result of peat degradation and mineralization following artificial drainage. In this study, we aimed at deducing changes in solute transport properties of peat soils differing in OM content. Miscible displacement experiments were conducted on 70 undisturbed soil columns with OM contents ranging from 11 to 86% w/w under saturated steady‐state conditions using tritium and bromide as conservative tracers. Measured breakthrough curves (BTCs) were subjected to model analysis using three different approaches: single‐porosity model (SPM), mobile–immobile model (MIM), and two‐flow region model (TFRM). The results indicated that (i) nonequilibrium solute transport processes are common in peat soils; (ii) the TFRM improved predictions of BTCs with heavy tailing or two peaks; (iii) applied tracers, tritium and bromide, were retarded in peat soils with higher OM content; and (iv) pronounced preferential flow mainly occurred in peat soils with lower OM content. This type of strong preferential flow had a small ratio of measured to fitted pore water velocity and a greater ratio of velocities (vA/vB > 3.0) in the fast and slow transport region as obtained from the TFRM. We conclude that shallow groundwater resources are more likely to become polluted in drained and degraded fen peats that are used for agricultural purposes.Core Ideas
Solute transport properties of peat at various stages of degradation were investigated.
The two flow region model improved predictions of breakthrough curves with two peaks.
Applied solutes were retarded in peat soils with higher organic matter content.
Pronounced preferential flow mainly occurred in highly degraded peat soils.

Published: August 2017

Knowledge about environmental impacts associated with the application of anaerobic digestion residue to agricultural land is of interest owing to the rapid proliferation of biogas plants worldwide. However, virtually no information exists concerning how soil‐emitted N2O is affected by the feedstock hydraulic retention time (HRT) in the biogas digester. Here, the O2 planar optode technique was used to visualize soil O2 dynamics following the surface application of digestates of the codigestion of pig slurry and agro‐industrial waste. We also used N2O isotopomer analysis of soil‐emitted N2O to determine the N2O production pathways, i.e., nitrification or denitrification. Two‐dimensional images of soil O2 indicated that anoxic and hypoxic conditions developed at 2.0‐ and 1.5‐cm soil depth for soil amended with the digestate produced with 15‐d (PO15) and 30‐d (PO30) retention time, respectively. Total N2O emissions were significantly lower for PO15 than PO30 due to the greater expansion of the anoxic zone, which enhanced N2O reduction via complete denitrification. However, cumulative CO2 emissions were not significantly different between PO15 and PO30 for the entire incubation period. During incubation, N2O emissions came from both nitrification and denitrification in amended soils. Increasing the HRT of the biogas digester appears to induce significant N2O emissions, but it is unlikely to affect the N2O production pathways after application to soil.Core Ideas
O2 planar optode images system and N2O isotopomer analysis were deployed.
O2 consumption was greater for digestate with a hydraulic retention time of 15 d than 30 d.
N2O production was smaller for digestate with a 15‐d hydraulic retention time.
Lower N2O emission for 15‐d retention time digestate was due to higher complete denitrification.

Published: August 2017

Amitriptyline is a frequently prescribed tricyclic antidepressant. Although amitriptyline and its active metabolite, nortriptyline, have been widely detected in natural waters, their environmental fate due to photodegradation is poorly understood. Here we describe a study conducted to investigate the photodegradation of amitriptyline and its active metabolite under simulated sunlight. Neither amitriptyline nor nortriptyline underwent direct photodegradation, but rapid photosensitized degradation did occur in fulvic acid (FA) solutions. The photodegradation of amitriptyline and nortriptyline followed pseudo‐first‐order kinetics with rate constants 0.24 and 0.16 h−1, respectively, at pH 8.0 in air‐saturated FA solutions. The photodegradation of the substrates increased markedly with pH. The deprotonation of amitriptyline and nortriptyline facilitated the availability of nonbonding electrons on nitrogen (N‐electrons). The excited triplet state of FA (3FA*) was verified as the main reactive species responsible for the photosensitized degradation. An electron transfer mechanism for the interaction between substrates and 3FA* was proposed on the basis of a series of quenching experiments, kinetic model and photoproducts determination. Demethylation at the α‐carbon of amine and hydroxylation were two primary photochemical processes initiated by the electron transfer reaction in the air‐saturated FA solution; these were followed by generation of demethyl amine and mono‐hydroxylation isomers. Our results suggest that indirect photodegradation is an important elimination process for amitriptyline and its active metabolite in natural waters.Core Ideas
Amitriptyline underwent more rapid photosensitized degradation than nortriptyline.
3FA* is mainly responsible for the photosensitized degradation.
An electron transfer reaction between substrates and 3FA* occurred.
The photosensitization involved demethylation and hydroxylation processes.
In‐Field Variability of the Illinois Soil Nitrogen Test and Loss‐on‐Ignition Results for Nitrogen Management
Authors: Maresma Angel , Ketterings Quirine M. 
Published: August 2017

Core Ideas:
Spatial and seasonal variability in the Illinois soil N test (ISNT)‐N and loss‐on‐ignition (LOI) at 500°C can impact N recommendations.
Loss‐on‐ignition determination at 500°C and 360°C are highly correlated.
Loss‐on‐ignition and ISNT‐N show strong spatial structure among soils.
Soil nitrate sampling is less practical because of its large spatial variability.
Intensification of current sampling protocols is needed for LOI and ISNT‐N.
The Illinois soil N test (ISNT) with loss‐on‐ignition at 500°C (LOI500) adjustment can identify fields with low versus high soil N supply potential in New York. However, spatial and seasonal variability in ISNT‐N and LOI500 can influence soil N supply classifications. We aimed to determine (i) the influence of sample density on the ratio of ISNT‐N to the critical value for interpretations of ISNT results (ISNT‐NCritical), and N supply classification, (ii) the implications of change in spatial and temporal variability on ISNT‐N interpretations, (iii) the probability of obtaining accurate interpretations as impacted by sampling intensity, and (iv) the influence of using LOI500 equivalents [derived from loss‐on‐ignition at 360°C (LOI360)] on ISNT‐N interpretations. Two 4‐ha silage corn (Zea mays L.) fields were sampled (150 samples per field, 0–20 cm depth; 64 in regular 25 by 25 or 23 by 27 m grids, the remainder in a pattern optimizing lag distance distribution) in July and November. Semivariograms were constructed to investigate spatial dependence. Soil nitrate showed the weakest spatial dependence. Increasing sampling intensity to 3.75 samples ha‐1 reduced the confidence interval for ISNT‐N/ISNT‐NCritical while augmenting the probability (>95%) of obtaining estimates within the true field mean (±6.4%), resulting in consistent classifications. The LOI500 and LOI360 results correlated well (r2 = 0.78); using LOI500 equivalents derived from LOI360 produced identical classifications for 92% of the samples. Effective sampling protocols for ISNT‐N should include sampling at 3.75+ samples ha‐1 for consistent ISNT‐N interpretations, and LOI500 equivalents can be used to derive ISNT‐Ncritical values.
A Wet‐Chemical and Phosphorus K‐edge X‐ray Absorption Near Edge Structure Investigation of Phosphate Adsorption on Binary Mixtures of Ferrihydrite and Calcite: Implications for Phosphorus Bioavailability
Authors: Adam Nadia 
Published: August 2017

Core Ideas
Understanding P sorption complexity is critical to managing alkaline soil‐P.
Molecular and macro‐scale sorption are characterized in representative systems.
Preferential P sorption on ferrihydrite is seen in ferrihydrite–calcite mixtures.
Nonlinear P sorptive behavior in mineral–mixtures indicates mineral interaction.
An increase in P bioavailability is expected with soil reduction and pH increase.
A fundamental understanding of phosphorus (P) bioavailability in alkaline soils is critical to its better management in agricultural and environmental applications. The main objective of this study is to characterize phosphate speciation in the alkaline pH range (pH 8–9.5) in binary mixtures of ferrihydrite and calcite using a combination of wet‐chemical and P K‐edge X‐ray absorption near edge structure spectroscopy. Our results showed that ferrihydrite and calcite sorbed phosphate as an inner‐sphere surface complex with binuclear‐bidentate mode of phosphate bonding on ferrihydrite in both single‐ and mixed‐mineral systems of ferrihydrite and calcite. Phosphate sorbed preferentially on ferrihydrite in binary mixtures of ferrihydrite and calcite particularly at higher concentrations of sorbed phosphate, probably due to greater concentration of metal‐OH surface sites in ferrihydrite than in calcite. In addition, phosphate sorption in mineral mixtures did not behave as a linear combination of phosphate sorption in their single‐mineral components, indicating mineral interactive effects. Molecular‐scale insights from this study have important implications for macro‐scale behavior of P bioavailability in alkaline soils, such as an increase in P bioavailability and subsequent P release with soil reduction and pH increase.

Published: August 2017

Core Ideas:
Cover crops significantly increased soil organic C compared with no cover crop management.
Perennial biofuel and cover crops had significantly higher volumetric heat capacity than row crop management.
Under laboratory‐controlled conditions, perennial biofuel and cover crops improved soil thermal properties.
Heat transport is an important factor that can influence the soil environment. The objective of this study was to determine if perennial biofuel and cover crops could alter soil thermal properties. Experimental treatments included two levels of cover crops (cover crops [CC] vs. no cover crops) [NC], collectively called row crops (RC), and two biofuel crop treatments. Cover crops used included cereal rye (Secale cereale L.), hairy vetch (Vicia villosa subsp. villosa), and Austrian winter pea [Pisum sativum subsp. arvense (L.) Asch. & Graebn]. The two biofuel treatments included perennial biofuel crops (PB): giant miscanthus (Miscanthus × giganteus J.M. Greef & Deuter ex Hodkinson & Renvoize) and switchgrass (Panicum virgatum L.). Soil samples were collected at 10‐cm depth increments from the soil surface to a depth of 30 cm. Soil thermal properties (thermal conductivity [λ], volumetric heat capacity [CV], thermal diffusivity [D]), and volumetric water content (θ) were determined at 0, ‐33, ‐100 and ‐300 kPa soil water matric potentials. Additionally, bulk density and soil organic C (SOC) were determined. Results showed that PB had 11% higher CV at saturation, probably because they had significantly higher θ and SOC than RC management. Cover crops had 13% higher CV at saturation probably because they had significantly higher θ and SOC than no cover crop management. Row crops had significantly higher λ and D than PB. The results from the current study imply that CC and PB can change soil thermal properties by reducing λ and D and increasing CV under laboratory conditions.

Attitudes of FPI (Islamic Defenders Front) in Indonesia so far impressed 'frontal' and against any form of indecent behavior. Their action, in fact it can be said as one of the deepest expression of a group of Muslims in articulating religious teachings are embraced, or as an attitude of "piety" in viewing of all the different faiths in the belief that he believes. Especially in view of problems that are clearly regarded as a form of disobedience, apostasy and blasphemy. The responses and reactions, as well as research that has been conducted by the author in Surabaya is in order to uphold the principles of faith are considered "correct" earlier. This paper aims to provide comprehensive information on what factors underlie the birth of contemporary religious groups-particularly FPI in Surabaya. And find the religious understanding, activity and movements FPI group in the area. Overview of the results of this study are expected to eventually be able to eliminate the possibility of misunderstanding information is the cause of the onset of prejudice and stereotypes is the first step in conflict or resolve conflicts between religious communities in a comprehensive manner. Therefore, the known diversity of religious groups with the dynamics of movements will make it easier for religious communities to learn from each other. Sikap-sikap FPI (Front Pembela Islam) di Indonesia selama ini terkesan ‘frontal’ dan melawan setiap bentuk kemunkaran. Aksi mereka, sebenarnya bisa dikatakan sebagai salah satu bentuk ekspresi terdalam dari sekelompok orang muslim dalam mengartikulasikan ajaran-ajaran agama yang dipeluknya, atau sebagai bentuk sikap “kesalehan” dalam memandang setiap keyakinan yang berbeda dengan keyakinan yang diyakininya. Apalagi dalam memandang persoalan yang jelas-jelas dianggap sebagai bentuk kemaksiatan, kesesatan dan penodaan agama. Maka respons dan reaksi mereka, sebagaimana hasil penelitian yang telah dilakukan penulis di Surabaya adalah dalam rangka menegakkan prinsip keimanan yang dianggap “benar” tadi. Tulisan ini bertujuan untuk memberikan informasi yang komprehensif tentang faktor apa saja yang melatari lahirnya kelompok-kelompok keagamaan kontemporer—terutama sekali FPI di Surabaya. Sekaligus mengetahui pemahaman keagamaan, aktifitas dan gerakan-gerakan kelompok FPI di daerah tersebut. Gambaran hasil penelitian ini pada akhirnya diharapkan mampu mengeliminasi kemungkinan kesalahpahaman informasi yang menjadi sebab timbulnya prejudice, dan stereotype yang merupakan langkah awal terjadinya konflik atau mengatasi konflik antar komunitas agama secara komprehensif. Sebab, dengan diketahui keanekaragaman kelompok-kelompok keagamaan dengan dinamika gerakannya akan lebih memudahkan masyarakat agama untuk saling belajar satu sama lain.
AKAR TERORISME DALAM ISLAM?

Terrorism has been a popular issue since September the Eleven. The incident was followed by a proclamation of war against terrorism by the US governments. The US invited other countries to join the campaign with President George W. Bush's monumental saying "You are either with us or against us". The effort of countering terrorism by the US and other countries with a weapon is likely to be ineffective. Countering terrorism, especially religious motivated terrorism can effectively be conducted by understanding the root causes of terrorism and eliminating what so-called global injustice.Terorisme menjadi isu populer sejak 11 September (2001). Insiden ini diikuti dengan sebuah proklamasi perang melawan terorisme oleh pemerintah USA. USA mengajak negara-negara lain untuk bergabung kampanye dengan perkataan monumental Presiden George W. Bush, ”Anda bersama kami, atau melawan kami.” Usaha menghadapi terorisme oleh USA dan negara-negara lain dengan senjata tampaknya tidak efektif. Melawan terorisme, khususnya terorisme yang dimotivasi oleh agama, bisa efektif dilakukan dengan memahami akar penyebab terorisme dan mengeliminasi apa yang disebut ketidakadilan global
