​​Genetic Variability of Wheat (Triticum aestivum L.) in Different Agro-climatic Zone of Western Himalayan Region of Pakistan
Authors: Mumtaz Nosheen , Khan Muhammad Qayyum
Published: August 2022

Background: Triticum aestivum L. (Wheat) is vital grain crop used globally as a staple food. The increasing population is posing a great challenge for agriculture sector especially to secure the availability of wheat. In Pakistan, from the last few years’ wheat productivity has improved but it is still far less than other countries. Its low productivity is attributed to various factors like weeds, pests, diseases, soil fertility and moisture. To overcome these obstacles, there is a dire need to assess the genetic variability of wheat by rapid and reliable methods. Observations for nine morphological traits were noted and analysis was done at 0.05 probability level. Methods: To study the genetic variability in wheat (Triticum aestivum L.) genotypes a field experiment was done during 2017 and 2018 at two different locations Rara and Danna of Muzaffarabad. Hundred wheat genotypes were investigated by using simple lattice design with 4 replications. Analysis of the observations for nine morphological traits was carried out at 0.05 probability. Result: High values for phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) were noted for grain yield (16.44 and 17.07%) and (14.75 and 15.94%) at both locations, separately. High heritability were obtained for plant height (98.80%) harvest index (96.84), thousand grain weight (95.47), spike length (94.91) and grain yield (92.80) at Rara and plant height (98.09), thousand grain weight (95.66), harvest index (93.32) and number of grain (91.28) at Danna. High genetic advance values were noted for number of tiller (53.45 and 42.89) at both locations. It is concluded from this research that estimation of the variability, heritability and genetic advance in the wheat genotypes (Triticum aestivum L.) is important in the plant breeding, because it might be used for improvement of novel varieties by breeders of wheat at relevant location.

Convergencias y divergencias en el entorno mediático-digital
Authors: Aruguete Natalia
Published: August 2022

La emergencia de las plataformas digitales permite la producción y circulación de contenidos casi en tiempo real y marcan el pulso de una cultura comunicacional crecientemente interactiva. La virtualización de la vida social caracteriza el nuevo ecosistema mediático-digital, donde las redes sociales son entidades jerárquicas, plagadas de asimetrías entre los usuarios y por una alta concentración de la información. En este escenario dinámico y cambiante, el vínculo entre comunicación y política también se ha visto transformado. Juan Bogliaccini lo analiza en una de las entrevistas que integran este número de InMediaciones de la Comunicación, interesado en seguir pensando, como lo hicimos en el Vol. 17 – Nº 1 publicado a comienzos de 2022, el poder de los medios, su uso estratégico en diversas coyunturas y realidades, la política y el lugar de las redes sociales en el mundo contemporáneo.

Dinámicas de antropización geomorfológica en el municipio de Chía (Cundinamarca, Colombia)
Authors: Castiblanco Sierra Miguel Angel
Published: August 2022

En este artículo se describen y analizan las intervenciones y cambios antropogeomorfológicos para el territorio de Chía, situado en el centro de Colombia sobre la cordillera Oriental andina. La investigación se fundamentó en los adelantos de la subdisciplina “antropogeomorfología” y se elaboró a partir de revisión documental, fotointerpretación de insumos, trabajo de campo y el examen cuantitativo de datos. Los resultados muestran un recuento de las acciones humanas, con ejemplos gráficos del fenómeno y caracterizaciones a escala 1:10.000 para cuatro periodos de referencia (1940, 1977, 2000 y 2020). Se definieron, asimismo, patrones y tendencias de las intervenciones en relación con los sistemas morfogénicos naturales y se estimó la huella de las antropogeoformas en función de la magnitud de las excavaciones y acumulaciones artificiales. Se concluye que se presenta una primacía actual de los modelados urbanogénicos, de tránsito, gestión hídrica y residuos para los ambientes fluviolacustres del altiplano, mientras que en los flancos montañosos se destaca el predominio de los modelados agrogénicos y de minería, con el aumento de las morfologías suburbanas.

Published: August 2022

Retomando los aportes y reflexiones surgidas en el marco del foro homónimo, celebrado en octubre de 2020, en el texto se aborda la pertinencia de la cartografía participativa en diferentes contextos de disputa, despojo o reivindicación territorial que se viven en la región latinoamericana, sobre todo por el modelo extractivo neoliberal que impera en sus economías. Se hace énfasis en los procesos seguidos por los cinco colectivos participantes para la elaboración de materiales didácticos y su implementación. Esto permite entender que las guías, cartillas y manuales sirven en primer lugar como herramientas de sistematización de experiencias que cumplen un papel de mediación práctica, pedagógica y política en la reivindicación y la construcción de territorialidades diversas, contrahegemónicas o en resistencia. En segundo lugar, se convierten en instrumentos de transmisión de conocimientos tanto en el ámbito universitario, facilitando la incorporación de nuevas generaciones a este enfoque crítico y popular de la cartografía, como hacia otros sectores o territorios en contextos similares. Finalmente, evidenciamos algunos de los retos éticos y pedagógicos de estos materiales de elaboración colectiva que, más que un producto de difusión, fungen como dispositivos de diálogo y reflexión desde y para la acción territorial.
Los contenidos científicos en los textos escolares para educación primaria rural colombiana
Authors: Giraldo Elida , Monsalve Carlos
Published: August 2022

Este artículo hace parte de un estudio sobre los contenidos científicos escolares (CCE) en las escuelas primarias rurales de Colombia. En específico, se analizan los contenidos científicos en los textos escolares que hacen parte de la propuesta curricular del modelo de escuela nueva. Se utiliza un enfoque cualitativo, mediado por el análisis de contenido de los textos escolares, para evaluar los CCE desde el nivel conceptual, las formas en que se presentan, su contribución a la formación científica de los estudiantes y las relaciones que se establecen entre ellos. Entre los resultados, se destacan la presentación de contenidos con imprecisiones o falencias en las definiciones y la poca relación entre los diferentes CCE tanto en los ámbitos intra- e intergrado como en las diferentes ciencias naturales que se enseñan en la escuela ―biología, física y química―. Esto mostraría que desde el currículo hay una mirada parcializada de las ciencias naturales, la cual promueve errores conceptuales que fomentan concepciones deformadas sobre la ciencia.
Resilience needs of retrenched workers: An intervention study of retrenched workers in Harare, Zimbabwe.
Authors: Kwembeya Maurice , Mbaliyezwe Dhlomo-Sibiya Rosemond
Published: August 2022

The intervention study explored the resilience needs of retrenched workers aged between 27 and 57 years. Purposive sampling was used to select a sample size of 19 participants. The sample size was determined by the saturation level which occurred when the participants were repeating responses. The participants had varied educational backgrounds and previous work-related experiences. In-depth interviews were conducted, using semi-structured interview guides, to collect data on the resilience needs of the sample. Data were grouped into themes, categories, subcategories and analysed using content analysis. The study found out that prematurely loss of employment through retrenchment brings a sense of hopelessness, helplessness, uncertainty, guilt and shame. It was found that social connectedness, relational structures and emotional regulation are important protective factors of building resilience in the face of employment loss. Functional cognitive skills enabled the retrenched workers to exercise positive thinking.  Professional mental health counselling services helped to restore the lost hope and confidence among the retrenched workers.

Methods. We used data from the 1984 to 2019 waves of the Panel Study of Income Dynamics to follow a balanced panel of 1406 individuals from birth through ages 20 to 36 years. We measured food insecurity from 1999 to 2003 and 2015 to 2019 among those who resided in low-income households during childhood.

Results. Twenty-eight percent of individuals who resided in low-income households during childhood exhibited improved food security status from childhood to adulthood. Those who participated in SNAP and WIC during childhood had 4.16-fold higher odds (95% confidence interval [CI] = 1.91, 9.03) of being more food secure than those who were eligible for but did not receive SNAP or WIC, and those who participated in SNAP alone had 3.28-fold higher odds (95% CI = 1.56, 6.88).

Conclusions. Participation in social safety net programs such as SNAP and WIC during childhood helps to improve food security across the life course. Our findings add evidence regarding the long-term benefits of participation in SNAP and WIC during childhood. (Am J Public Health. 2022;112(10):1498–1506. https://doi.org/10.2105/AJPH.2022.306967 )

This report documents the geomorphic assessment component of the Old River, Mississippi River, Atchafalaya River, and Red River System Technical Assessment. The overall objectives of the geomorphic assessment are to utilize all available data to document the historic trends in hydrology, sedimentation, and channel geometry for the rivers in the vicinity of the Old River Control Complex and to summarize the changes observed at locations where repetitive datasets exist and at key reaches that are determined during the study. The geomorphic assessment tasks include data compilation, geometric data analysis, gage and discharge analysis, dredge record analysis, sediment data analysis, development of an events timeline, and integration of results. Geomorphic reaches were developed, and the morphological trends during different time periods were identified. The geomorphic assessment highlighted the importance of considering spatial and temporal variability when assessing morphological trends.
Technical assessment of the Old, Mississippi, Atchafalaya, and Red (OMAR) Rivers : channel geometry analysis
Authors: Little Charles , Biedenharn David
Published: August 2022

The Old River Control Complex (ORCC) consists of the Low Sill, Auxiliary, and Overbank structures as features of the Old River Control Structure (ORCS) and the privately owned hydro-electric power plant. Operations of the ORCC manage the hydrologic connectivity between the Mississippi River and the Atchafalaya River/Red River systems. The morphology of the Old, the Mississippi, the Atchafalaya, and the Red Rivers (OMAR) has been influenced by the flow distribution at the ORCC, as well as the accompanying bed sediments. A geomorphic assessment of the OMAR is underway to understand the morphological changes associated with operation of the ORCC. Supporting the geomorphic assessment, a channel geometry analysis herein documents observed adjustments of the affected river channels. Historical hydrographic survey data were used in the Geographic Information System to create river channel geometric models, which inform the analysis. Geometric parameters for cross sections and volume polygons were computed for each survey and evaluated for morphological trends which may be ascribed to the influence of the ORCC. Additionally, the geometric parameters for the Atchafalaya River were used to extend the geometry analyses from the 1951 Mississippi River Commission report on the Atchafalaya River, which was the primary catalyst for the initial development of the ORCS.

Roof fall in phosphate mines seriously endangers the safety of the mining activity. In this paper, the risk of roof fall occurring in phosphate mines is evaluated using the underground phosphate mine in Shanshuya, China, as an engineering background. The factors affecting roof fall in phosphate mines are analyzed, and an index system for evaluating the risk of roof fall in phosphate mine is established. Four evaluation models are employed to evaluate the risk of roof fall occurring: a set pair analysis model based on combination weights, a comprehensive fuzzy model based on hierarchical analysis, an approximately ideal ranking model based on entropy weight, and a gray relational analysis model. The evaluation results of the first two models are moderate risk with a bias toward intense risk. And the evaluation results of the last two models are slight risk with a bias toward moderate risk and moderate risk with a bias toward slight risk, respectively. The suitability of each of the evaluation models is analyzed which reveals that the evaluation results obtained using the different models are inconsistent. A combined evaluation method based on the four original evaluation models is subsequently proposed. Application of the combined evaluation method to the Shanshuya phosphate mine produces results that the roof fall risk is moderate with a bias toward slight risk. It is consistent with the actual situation in this phosphate mine. The results of the study can be used to provide technical support to engineers evaluating the risk of roof fall occurring in similar phosphate mines.

The CORDEX Flagship Pilot Study ELVIC (climate Extremes in the Lake VICtoria basin) was recently established to investigate how extreme weather events will evolve in this region of the world and to provide improved information for the climate impact community. Here we assess the added value of the convection-permitting scale simulations on the representation of moist convective systems over and around Lake Victoria. With this aim, 10-year present-day model simulations were carried out with five regional climate models at both PARameterized (PAR) scales (12-25km) and Convection-Permitting (CP) scales (2.5-4.5km), with COSMO-CLM, RegCM, AROME, WRF and UKMO. Most substantial systematic improvements were found in metrics related to deep convection. For example, the timing of the daily maximum in precipitation is systematically delayed in CP compared to PAR models, thereby improving the agreement with observations. The large overestimation in the total number of rainy events is alleviated in the CP models. Systematic improvements were found in the diurnal cycle in Top-Of-Atmosphere (TOA) radiation and in some metrics for precipitation intensity. No unanimous improvement nor deterioration was found in the representation of the spatial distribution of total rainfall and the seasonal cycle when going to the CP scale. Furthermore, some substantial biases in TOA upward radiative fluxes remain. Generally our analysis indicates that the representation of the convective systems is strongly improved in CP compared to PAR models, giving confidence that the models are valuable tools for studying how extreme precipitation events may evolve in the future in the Lake Victoria basin and its surroundings.

A clinical efficacy study of 0.025-inch guidewires (GWs) according to mechanical property analysis has not been reported yet. This study was designed to evaluate the clinical efficacy of a newly developed 0.025-inch GW for biliary access according to the basic mechanical property. Commercially available 0.025-inch GWs were in vitro tested based on parameters of mechanical property. Patients with naïve papilla requiring diagnostic or therapeutic ERCP were randomly assigned to an experimental 0.025-inch newly developed GW or a control 0.025-inch GW group. Technical success rate of wire-guided cannulation (WGC), difficult biliary cannulation (DBC), and adverse event rates were measured in this multicenter randomized trial. The technical success rate of primary WGC was 79.1% (151 of 191) in the experimental group and 70.8% (131 of 185) in the control group (95% two-sided confidence interval: 8.25%; p<0.001; for a noninferiority margin of 15%). The technical success rate including cross-over to each other was also non-inferior. However, the chi-square test showed a statistical difference (81.7% vs. 68.1%; p=0.002). Median biliary cannulation time was shorter in the experimental group (53 seconds vs. 77 seconds; p=0.047). The rate of DBC was more frequent in the control group (34.6 % vs. 50.3% p=0.002). Multivariate analysis revealed that control group was one of contributing factors for DBC. Overall rate of post-ERCP pancreatitis was not different (4.7% vs. 8.6%; p=0.125). WGC using a newly developed GW with superior physical performance GW in a bench test showed similar clinical efficacy and the rate of DBC was significantly lower in experimental GW.

A study was attempted to take stock of the conventional underutilised edible plants available in the Kokrajhar district of Assam, NE India having ethno-medicinal properties and utilised as a source of herbal medicines by the tribal people of the district. The district is demographically inhabitted by Bodos, Rava, Koch Rajbongshi, Santhal, Orao, Muslim, Nepali, Bengali, etc., and the Bodos are the commanding inhabitants of Kokrajhar district of Assam, belonging to the schedule tribe (plain). They are mainly dependent on edible plant resources growing wild in natural habitats for their day-to-day activities. Vegetables are the protective foods that play an important role in a balanced diet. Vitamins, micronutrients, and pharmaceuticals are necessary for the correction of deficiency disorders and diseases. Utilization of underutilised edible plant resources as vegetables as well as herbal medicinal sources by the tribal communities is a common practice. However, with the change in eating habits of the people in recent times, the popularity of the same has declined among the new generations. An attempt has been made to document traditional and underutilised vegetables having medicinal properties to make the common masses aware. The methodology included a structured questionnaire, personal interviews with the village headman and knowledgeable elderly people, group meetings and discussions with both young and elderly people, women, and also the local vegetable traders. In the present study, 76 plant species belonging to 41 families have been documented, which were used as sources of vegetables and also used in the treatment of different diseases. The wealth of plant resources recognised and documented in the study included varied types of herbs, shrubs, climbers, and some trees.

Background: Hemodynamic stabilization is a core component in the resuscitation of septic shock. However, the optimal target blood pressure remains debatable. Previous randomized controlled trials suggested that uniformly adopting a target mean arterial pressure (MAP) higher than 65 mmHg for all adult septic shock patients would not be beneficial; however, it has also been proposed that higher target MAP may be beneficial for elderly patients, especially those with arteriosclerosis. Methods: A multicenter, pragmatic single-blind randomized controlled trial will be conducted to compare target MAP of 80–85 mmHg (High-target) and 65–70 mmHg (Control) in the resuscitation of septic shock patients admitted to 28 hospitals in Japan. Patients with septic shock aged ≥ 65 years are randomly assigned to the high-target or control groups. The target MAP shall be maintained for 72 h after randomization or until vasopressors are no longer needed to improve patients' condition. The primary outcome is all-cause mortality at 90 days after randomization. To minimize the adverse effects related to catecholamines, if norepinephrine dose of ≥0.1 µg/kg/min is needed to maintain the target MAP, vasopressin will be initiated. Other therapeutic approaches, including fluid administration, hydrocortisone use, and antibiotic choice, will be determined by the physician in charge based on the latest clinical guidelines.Discussion: The result of this trial will provide great insight on the resuscitation strategy for septic shock in the era of global aged society. Also, it will provide the better understanding on the importance of individualized treatment strategy in hemodynamic management in critically ill patients.Trial Registration: UMIN Clinical Trials Registry; UMIN000041775.
