Reforms for culmination of the deadlock in appellate body of WTO: An agenda of saving the multilateral trading system
Authors: Khan Asif , Wu Ximei
Published: September 2021

The World Trade Organization's (WTO’s) dispute settlement mechanism, known as the "pearl in the crown," is stalled due to United States (U.S.) obstruction, which prevents appellate body members from being ordained. This situation continues, and the WTO’s dispute settlement function is paralyzed since 2019. The WTO has faced a crisis in recent years, and the trade legislation has stagnated. The dispute settlement body was also blocked due to U.S. interference, which led to the failure of the appellate body’s members to be selected. The data has been gathered for this descriptive study using secondary research method, including different newspaper articles and the internet, which were outlined and noted. This paper presents and evaluates several existing proposals on how to get out of the impasse. This paper points out whether the existing WTO members can choose to join or not participate in establishing a new appellate body. On this basis, it makes its own relatively unique proposal, namely, to establish a substantial dispute settlement mechanism outside the WTO, parallel to the existing dispute settlement mechanism, and it demonstrates the legal feasibility of the proposal. Immediately, the states should begin negotiations on the significant agreements required for this new appellate body. It will effectively solve the deadlock in the dispute settlement mechanism caused by the United States, blocking the appointment of members of the appellate body.

Las complicaciones ocurrieron en 41,2%: infección de colección (2 casos), perforación, sangrado en zona de drenaje, obstrucción de prótesis plástica, migración de prótesis al interior de colección y al lumen gástrico (1 caso cada uno). El manejo quirúrgico de éstas complicaciones fue necesaria en 3 casos, mientras que en los otros 4 casos solo requirió manejo médico – endoscópico. Conclusiones: los drenajes guiados por ecoendoscopía de las colecciones liquidasperipancreáticas tienen alta tasa de éxito técnico y clínico con reducido porcentaje de complicaciones.
Hepatitis A and hepatitis E virus co-infection with right pleural effusion, ascites and acute acalculous cholecystitis. A case report
Authors: Iza Palacios Luis , Espinoza- Ríos Jorge
Published: September 2021

Hepatitis A and hepatitis E are the leading causes of acute viral hepatitis in developing countries due to our poor sanitaryconditions, both spread by fecal-oral route or through contaminated water and food. Being both self-limiting diseases, they are usually benign but may present with atypical clinical findings. A 32 year-old female with right pleural effusion, ascites and acalculous cholecystitis during the course of HAV and HEV co-infection is reported. Clinical improvement was observed with conservative management. As far as we know, this is the first case described of a patient with these three complications in thebackground of a hepatitis A virus and hepatitis E virus co-infection.
Juvenile “idiopathic” arthritis (JIA) as a manifestation of food allergy. Case Study
Authors: Muñoz-Urribarri Ana Beatriz , Delgado Godos Alex Gamaniel , Castillo Durand Raúl , Quispe Huarcaya Michael Algio , Calderón Flores Roxana Stephanie Hilda
Published: September 2021

Studies linking type of diet and juvenile idiopathic arthritis (JIA) have variable results and are inconsistent. This case shows an evolution which fulfilled the criteria of JIA, but was diagnosed as food allergy. Case: A seven-year old boy had fever, arthralgia, general malaise, headaches, abdominal pain and rashes. These symptoms were diagnosed as fever of unknown origin (FUO) and probable JIA. There was a stabbing pain in the right iliac fossa. An upper and lower endoscopy were performed and nodular ileocolitis was detected. A hypoallergenic diet was prescribed, in addition to mesalazine and oral corticosteroids. The patient was asymptomatic for 2.5 months and then relapsed with all symptoms after consuming dairy. This JIA case shows the diagnostic phases of food allergy: improvement and recurrence of symptoms with the reintroduction of the allergen (oral challenge=gold standard of food allergy). There is evidence that supports the existence of a gut-joint axis, where the luminal content triggers a series of immunologically mediated reactions that can cause systemic diseases such as J other connective tissue diseases. This case report adds reasonable evidence in support of food allergy as a cause of JIA.
Fibromatosis tipo desmoide de apéndice cecal: reporte de caso inusual y revisión de la literatura
Authors: Bravo-Taxa Mercedes , Vásquez-Vásquez Carlos Luque , López-Blanco Aldo , Taxa-Rojas Luis
Published: September 2021

Antecedente: La fibromatosis tipo desmoide es un proceso neoplásico benigno no encapsulado localmente invasivo y agresivo, que se origina de la proliferación de fibroblastos y miofibroblastos aparentemente normales. La localización más frecuente de la fibromatosis es extra-abdominal (60%), pared abdominal (25%) e intra-abdominal (8-15%), en raras ocasiones puede originarse en las vísceras (0,73%), como el páncreas, unión gastroesofágica, diafragma y apéndice. La incidencia anual de tumor desmoide se estima de 2 a 5 casos por millón. En el presente artículo, reportamos un caso de presentación inusual, originado en el apéndice cecal. Caso: Paciente de sexo femenino de 41 años con dolor pélvico agudo, que ingresa a sala de operaciones con diagnóstico clínico y ecográfico de probable tumor de ovario a pedículo torcido. En el intraoperatorio se evidenció una tumoración sólida de 15 cm de diámetro que dependía del apéndice cecal, correspondiendo el estudio anatomopatológico a tumor desmoide de apéndice cecal. Conclusiones: El tumor desmoide puede originarse en diversas localizaciones extra e intra-abdominales, siendo esta última la más rara y agresiva. El diagnóstico preoperatorio exacto es muy difícil y casi siempre los pacientes ingresan al quirófano con sospecha diagnostica de tumoración intraabdominal de etiología desconocida. Los factores de riesgos asociados a su aparición aún no se encuentran caracterizados, siendo la resección quirúrgica completa del tumor -con márgenes quirúrgicos li embargo, el riesgo de recurrencia es alto incluso con la remoción óptima del tumor.

Published: September 2021

La colangiopancreatografía retrógrada endoscópica (CPRE) representa el tratamiento de primera línea para el drenaje biliar en pacientes con obstrucción biliar maligna avanzada. Sin embargo, este procedimiento representa un desafío en pacientes con anatomía alterada quirúrgicamente. El ultrasonido endoscópico (USE) permite la toma de muestras de tejido mediante punción aspiración con aguja fina y también representa una alternativa de drenaje biliar al abordaje percutáneo o quirúrgico. Nuestro objetivo es comunicar un caso en el que la ecoendoscopia permitió el diagnóstico definitivo de la recurrencia de la enfermedad oncológica de base y el alivio de la obstrucción biliar en un paciente con anatomía alterada quirúrgicamente.

The sequences of creative impulse and stylistic trends of ceramic practices in the art school from inception have not received scholarly attention in terms of the examination of the approaches towards the conceptions. The specific objective is to investigate the inception of eclecticism in the art school and circumstances behind the conceptions in order to reveal the contextual definitions of used designs and factors influence the innovation.

Methodology: Descriptive and analytical approaches were used to trace decorative trends of each phase and the integration of the various motifs and styles of the previous phases in the new phases that sprung up. Samples of ceramic wares in the art school exhibition brochures, galleries and ceramic studios were collected for analysis and photographs were also taken for evidence.

Findings: In concept, the praxis reveals traditional ideology at inception and desegregation of different themes, ideas, and styles in the recent phase of the practice. The practices are eclectic inclined as of late with reflection of traditional ideology, contemporary issues and customs of Western societies. Notwithstanding, the ceramic art tradition of the art school is aesthetically inclined both in principle and practice.

Unique contribution to theory, policy and practice: No doubt, the sculptural creativeness of Ife wares has preserved cultural heritage for public awareness. This is largely evident in the proliferation of her ingenious adaptation of indigenous deco-stylistic techniques with Western influence that portrayed Nigerian traditional culture by themes, forms and styles in concepts and renditions.

Purpose: This paper examines transition from Preschool to Standard One in the Early Childhood Education programme implemented in 2013 in Botswana public primary schools.

Methodology: The methodology employed in this study is the qualitative approach with multi-case study technique to investigate the implementation of the Early Childhood Education programme. Transitional Bilingual Education is used as the theoretical framework to benchmark the realities of transition from Preschool to Standard One classrooms. Data collection was done using open ended questionnaires, interviews, focus group discussions and scrutiny of learners’ artifacts.

Results: The findings indicated that transition is not smooth due to the languages of instruction used at both Preschool and Standard One, learners who do not attend Preschool and lack of teacher aides in Standard One classes. The study concluded that there must be harmonization of languages of instruction at both levels to enable smooth transition.

Unique contribution to theory, policy and practice: Lastly, the study recommends compulsory Preschool learning for all young learners before entry into Standard One.

Purpose: This study explored the effect of Concept Mapping Instructional Strategy Accompanied by Discussion Web on students’ academic achievement in the concept of Genetics at Navrongo Senior High School, generally, and on gender basis.

Methodology: The study adopted quasi-experimental design (pretest, posttest non-equivalent design). The sample comprised of 80 Navrongo Senior High School Form Three Gold Track and Green Track science students. Students from the Green Track class and Gold Track class were assigned experimental group and control group respectively. The experimental group class was made up of 23 males and 20 females. The control group class was also made up of 24 males and 13 females. Pretest was administered to all the participants. The experimental group was taught using Concept Mapping Instructional Strategy Accompanied by Discussion Web. The control group was taught using Conventional Teaching Method. A posttest was administered to both groups to determine the effectiveness of the treatment. The reliability of the test items was determined using test-retest reliability coefficient. The test-retest reliability coefficients of the instruments were found to be 0.70 and 0.73 for the pretest and posttest respectively. The data obtained were analysed using t-test.

Results: The pretest test scores revealed that the students were homogeneous in terms of academic achievement (t-value = 1.05, p-value=0.30, p>0.05). Posttest results of students in the experimental group were significantly higher than the control group (t-value = 8.07, p-value = 0.000, p < 0.05). The result of the posttest showed that the use of concept mapping instructional strategy accompanied by discussion web in teaching genetics was more effective than conventional teaching method. There was no statistically significant difference in the academic achievement of male and female students in the experimental group (t-value = 1.68, p-value = 0.11, p > 0.05).

Unique contribution to theory, practice and policy: This study recommended that Biology teachers in Navrongo Senior High School should be encouraged to teach Genetics using Concept Mapping Instructional Strategy Accompanied by Discussion Web in order to improve the academic achievement of students. Science teachers should be given the opportunity to attend workshops, seminars, conferences to enable them update their knowledge on current instructional strategies that are capable of improving the academic achievement of students. The Government, Ghana Education Service and Ministry of Education should establish professional development fund for teachers to enable them upgrade professionally and also improve on their teaching styles since most teacher are not abreast with the current or modern methods of teaching.

Auburn University (Auburn, Alabama, U.S.) was used as a site for a case study evaluating the standard plot sampling protocol for i-Tree Eco. A 100% tree inventory of the managed areas of campus was conducted in 2009–2010 and provided a complete data set for the evaluation. Air pollution removal, carbon storage, and carbon sequestration were the ecosystem services examined. Total tree population was also utilized for this assessment to provide a comparison to i-Tree Eco protocol. To achieve an estimate with a ±10% allowable error of the total campus value, 622 plots (0.04 ha each) with at least one tree present would need to be inventoried for air pollution removal, 870 plots for carbon storage, 483 plots for carbon sequestration, and 258 plots for number of trees, as opposed to the standard i-Tree Eco protocol of 200 plots. This study provides a first step in evaluating i-Tree Eco sampling protocol; however, efforts testing these results at sites throughout the southern United States are needed to provide the most accurate estimate of plot numbers necessary for predicting ecosystem services of urban forests.

Managing and Monitoring Tree Health and Soil Water Status During Extreme Drought in Melbourne, Victoria
Authors: May Peter , Livesley Stephen , Shears Ian
Published: September 2021

Drought can lead to mortality in urban tree populations. The City of Melbourne, Victoria, Australia, manages a large population of trees that provide important ecosystem services and cultural heritage values. Between 1997 and 2009 Melbourne was affected by a serious drought resulting in significant tree health decline. Elms and planes in particular, were badly affected. This paper presents data from a survey of tree health status, and of studies of retrofitted buried drip line irrigation. A study of soil wetting in autumn of 2009 found that the use of drip irrigation had, in most cases, little or no effect on soil moisture levels and a modeled study of tree water use showed that water delivered by drip irrigation provided only a fraction of the water required by a mature tree. By contrast, drip irrigation in late winter was able to recharge soil moisture levels. Mechanisms responsible for the decline in tree health seen during the drought are discussed. While the drought has temporarily been alleviated, climate change scenarios for southern Australia suggest that increased rainfall variability and drought events will be more common. The experiences gained during the recent drought event provide useful information for urban tree managers planning for the future.
Determining Variability in Characteristics of Residential Landscape Soils that Influences Infiltration Rates

Published: September 2021

Although composed mostly of sand, observations of new urban residential communities in Florida suggested relatively wide ranges in clay content and importation of offsite soils. Often these communities are constructed around surface water where heavy summer rains and intense landscape maintenance present concerns for surface water contamination. Due to land sculpturing, soil compaction and importation; onsite soil physical properties may differ from soil maps developed decades before. How much change and what changes occurred has seldom been quantified. This study examined soil characteristic data from diverse, newly constructed urban soils and examined relationships with soil infiltration rates. Samples were collected from 40 lots in nine newly established urban residential communities within Central Florida to quantify textural composition, bulk density (Db), moisture retention, and pore size distribution. Most lots (90%) contained sandy soil dominated by micropores (58% total mean pore space). Variability of Db was low with most communities exhibiting high soil compaction (>1.7 g cm-3), which may indicate potential plant root penetration concerns. Mean soil infiltration rates among communities were high (11 to 64 cm hr-1), with large variations (2.0 to 111.1 cm hr-1). Correlations between soil moisture retention volumes, Db, and infiltration rate did not occur. However, soil texture was a significant predictor of infiltration rate. Relationships between infiltration rates and soil characteristics were poor (r2 = 0.43) and suggest direct measurement of infiltration rate may be necessary. High infiltration rates, despite compaction, indicate reduced potential for surface water contamination if a sufficient natural fetch separates landscapes from water bodies.
