The 2013 curriculum encourages learners to have high-level high-level thinking skills high order thinking skills (HOTS). This requires teaching materials that are in line with the demands of the 2013 Curriculum such as Student Worksheets (LKPD). To develop LKPD in accordance with the demands of the 2013 Curriculum, it is necessary to analyze the needs of students about the LKPD. The purpose of this study was to see the needs of students' analysis of HOTS-based LKPD to hone higher order thinking skills so that students could think critically and creatively. This type of research is a descriptive study with a qualitative approach. The sampling technique was observation, interviews and questionnaires to students of SMPN 3 and SMPN 23 Padang. The results showed that the teaching materials available at SMPN 3 Padang and SMPN 23 Padang already used the 2013 Curriculum, but the LKPD used was only made by the Subject Teacher Conference. The LKPD made by the MGMP does not require students to analyze, evaluate and create which are indicators of HOTS. From the analysis of the curriculum, the two schools have implemented the 2013 curriculum, but in its implementate it has not emphasized a student-centered learning process. Based on the interview with the teacher, it was found that the problem in the learning process was that students were not used to higher-order thinking and there was no teaching material that specifically required students to improve higher-order thinking. Thus, the development of HOTS-based LKPD is very much needed.

Achievement and success in learning depends on several aspects. One aspect that really influences is how a teacher implements learning. The background of the writing of this article is based on the results of observations and interviews at school which show that the learning process still tends to be teacher-centered, and this also has an impact on the learning competences. One way that can be used to demand the activeness of students is by applying the learning model. Based on the literature study that has been conducted, the writer found a suitable learning model to overcome the problems found, namely the Student Facilitator and Explaining type of cooperative learning model. This type of research is a literature study using descriptive analysis. Based on the literature study conducted, learning using the Student Facilitator and Explaining type of cooperative learning model can improve the learning competence of students. It makes students as facilitators and is invited to think so that it will result in a deeper and more interesting exchange of information and lead to self-confidence in students. It is very helpful to improve the learning competence of students both in the aspects of attitudes, knowledge and skills.

Shareholding Patterns and Financial Performance: Evidence from the Banking Sector in Bangladesh
Authors:   Department of Accounting and Information Systems Jashore University of Science and Technology, Hossain Mohammad Kamal
Published: August 2021

This study attempts to examine the relationship between shareholding patterns and banks’ financial performance, as defined from three different dimensions, namely, profit-based performance measured by return on equity (ROE), market-based performance measured by Tobin’s Q (TQ) and valuebased performance measured by economic value added (EVA). It included 29 out of the 30 banks listed on the Dhaka Stock Exchange for the period 2013–2017, providing a balanced panel with 145 observations. All data were collected from the annual reports of the respective banks. The randomeffects GLS regression model was employed to test the chosen hypotheses. This study found a conflicting result, i.e. there was a relationship between some, but not all of the patterns of shareholdings and financial performance of the listed banks in Bangladesh. For example, a significant relationship between foreign shareholding and banks’ financial performance, as measured by ROE, TQ and EVA-log, was found. Sponsor-directors and general public shareholdings were found to be significantly related to ROE and EVA-log, but insignificantly associated with TQ. However, institutional and government shareholdings were insignificantly related to the banks’ financial performance, regardless of the measures employed to assess it. This study contributes to the existing literature by exploring the relationship between shareholding patterns and banks’ financial performance, and may indicate the need for a restructuring of the existing shareholding patterns in the banking sector in Bangladesh in order to maximise performance. This study is distinctive compared to prior studies, as it examines the relationship between the shareholding patterns disclosed in the annual reports of the sampled banks and banks’ performance, as measured by EVA-log along with ROE and TQ, which have not been covered earlier.

Published: August 2021

La problemática del éxito escolar preocupa tanto a nivel político como social. No obstante, a menudo se entiende desde una lógica hegemónica reduccionista en la que priman las calificaciones. El presente estudio tuvo como objetivo ahondar en la representación social que jóvenes sinaloenses de bachillerato tienen sobre el éxito escolar. Desde una aproximación estructural se pretende conocer cómo influyen en la representación del éxito escolar de los jóvenes tanto dicha lógica hegemónica como sus inserciones sociales. Los resultados muestran que los jóvenes relacionan el éxito con un arquetipo de estudiante exitoso, responsable y que se esfuerza mostrando interés. A su vez, entienden el aprendizaje desde una dimensión práctica donde lo fundamental es saber usar lo aprendido, más allá de las calificaciones obtenidas. Asimismo, se destaca la importancia del proceso y las pautas que permiten la permanencia y conclusión del bachillerato. El éxito escolar posibilita así un mejor futuro.
From colonial forestry to 'community-based fire management': the political ecology of fire in Belize's coastal savannas, 1920 to present
Authors: Smith Cathy
Published: August 2021

This article examines the past century of fire management of the coastal pine savanna in Belize, drawing on archival evidence,interviews, and ethnographic enquiry into an international development project in Belize. It considers contemporary approaches that seek to use prescribed fire with the participation of local communities in relation to past practices. The Belizean savanna has long been shaped by human fire use. Its flora is ecologically adapted to fire. Yet fire has been repeatedly cast as a problem, from c. 1920, by British colonial and, later, USA foresters, and, most recently, by international and local non-governmental nature conservation organizations. Informed by different schools of thought, each of these organizations has designed programs of fire management aiming to reduce wildfire frequency. Yet little has changed; Belize's diverse and growing rural population has continued to use fire, and the savannas burn, year upon year. While the planned aims and methods differed, each program of fire management has, in practice, been similarly structured and constrained by its genesis within colonial or international development. Funding and leadership for fire management has been inconsistent. Each program has been shaped by a specifically Belizean ecology and politics, in excess of its definition of the fire 'problem' and 'solutions' to it. Powerful political elites and fire users in Belize have not seen clear incentives for the fire management supported by official policy. This analysis highlights that contemporary efforts to build more ecologically and environmentally just forms of fire management must be understood in the context of broader political struggles over land and resources.
Randomized, blinded, controlled clinical trial to assess gastroesophageal reflux and regurgitation in dogs undergoing general anesthesia after hydromorphone premedication with or without acepromazine or dexmedetomidine
Authors: Costa Renata S. , Wetmore Lois A. , Stein Amy
Published: August 2021

OBJECTIVE

To investigate whether premedication with hydromorphone alone or combined with acepromazine or dexmedetomidine affects the incidence of gastroesophageal reflux (GER) and regurgitation in dogs undergoing general anesthesia for elective orthopedic surgery.

ANIMALS

39 healthy client-owned dogs undergoing general anesthesia for elective orthopedic surgery between November 2016 and November 2018.

PROCEDURES

For this prospective, randomized, controlled, blinded clinical trial, dogs were randomly assigned to be premedicated with hydromorphone (0.1 mg/kg, IM) alone (group H [control group]) or with either acepromazine (0.05 mg/kg, IM; group AH) or dexmedetomidine (6 μg/kg, IM; group DH) before undergoing general anesthesia induced with propofol and maintained with isoflurane. A pH sensor–tipped probe was used to identify episodes of GER (esophageal pH < 4 or > 7.5 for ≥ 30 seconds). Results for GER, regurgitation, vomiting, propofol dose, and durations of food withholding and anesthesia were compiled and compared across groups.

RESULTS

There were 13 dogs in each group, and no meaningful differences were detected in age, body weight, sex, breed, or durations of anesthesia or food withholding across groups. Overall, 16 of the 39 (41%) dogs developed GER: 9 in group H, 6 in group AH, and 1 in group DH. The incidence of GER was significantly lower for group DH versus group H. Six of the 39 (15%) dogs regurgitated: 4 in group H and 2 in group AH.

CONCLUSIONS AND CLINICAL RELEVANCE

The combined use of dexmedetomidine and hydromorphone as premedication may be a better choice to reduce GER in healthy dogs undergoing orthopedic surgery than would the use of hydromorphone with or without acepromazine. Additional research is warranted. (Am J Vet Res 2021;82:695–700)

Published: August 2021

El objetivo es analizar las características de implementación de la estrategia de Economía Circular para las botellas Polietileno Tereftalato (PET) y su influencia en la gestión del envase en Colombia, para su despliegue y operación. De acuerdo con Greenpeace International (2018) el estilo de vida de “usar y tirar” el envase ha desatado una emergencia que impacta la salud de los ecosistemas y de los seres vivos, con el uso de plástico. Las industrias tienen la necesidad de agilizar la migración de un modelo de “economía lineal”, que implica producir bienes, utilizarlos y desecharlos, hacia una “economía circular”, que maximice el uso de los recursos y convierta sus desechos en nuevos materiales (WEF, Ellen MacArthur Foundation and McKinsey y Company, 2016). Se aplicó una metodología descriptiva con análisis de contenido y entrevista en profundidad para caracterizar el uso de botellas PET en la industria de bebidas en Colombia. La investigación identificó la cadena logística reciclaje – depósito – transformador – productor – distribuidor – cliente – consumo, encontrando problemas en reciclaje; los productores de PET tienen nuevas responsabilidades, están constituidos por Postobón, Coca-Cola y Bavaria, los dos primeros lideran la aplicación de economía circular de PET desde hace una década.
Legal issues of compensation for damage caused to the environment as a result of oil spills
Authors: Kudelkin Nikolai
Published: August 2021

The subject of this research is the set legal norms that regulate public relations arising in the process of compensation for damage inflicted to the environment as a result of oil spills. The goal of this work consists in formulating the theoretical and practical conclusions and proposals on the improvement of the institution of compensation for environmental damage as a whole, and the legal aspects of compensation for damage inflicted to the environment due to oil spills in particular. The relevance of this topic is substantiated by the statistical data; for example, in the Arctic Zone of the Russian Federation, the total area of disturbed land as of 2019 was 218,641 hectares, and most of them (according to the data for the entire observation period) were formed due to the extraction of mineral resources, as well as a result of oil and spills during their transportation. In 2019, 17, 000 accidents related to oil spills took place in the Russian Federation, among which 10, 500 were the accidents on oil pipelines. The article explores the questions associated with compensation for environmental damage. The analysis of the effective legislation in this sphere and its practical implementation allowed making a range of conclusions It is noted that the mechanism of compensation for environmental damage in the Russian Federation has significant flaws, namely with regards to compensation for damage in kind, offsetting the costs incurred by the infliction of environmental damage to repair such damage. The issues related to the procedure of disbursement of compensation for environmental damage to restore the state of the environment remain open and virtually unresolved. Recommendations are made on solution of the indicated problems.

Understanding the cognitive differences in psychopathy: Emotional distraction across psychopathic traits
Authors:   , Bryant Conor
Published: August 2021

Emotional stimuli naturally draw our attention. In emotional distraction paradigms, such stimuli can interrupt performance on a simple cognitive task. There are, however, individual differences in the extent to which emotional distractors impact performance. Previous research has found that highly psychopathic people perform better than others in these tasks, indicating that they are less distracted by emotional stimuli. We tested two separate accounts of the cognitive differences in psychopathy. Emotional processing accounts believe the deficit is specific to processing of aversive stimuli. Conversely, the Attention deficit accounts suggest the deficit is rather ineffective processing of peripheral information. To tease these hypotheses apart we investigated emotional distraction using positive and negative peripheral distractors. Negative distraction but not positive distraction should be reduced if emotional processing accounts are correct; all types of distraction should be reduced for Attention-deficit accounts. The current study employs an emotional distraction paradigm that includes peripheral task-irrelevant distractors that vary in valence and arousal. We measured trait psychopathy using the Psychopathic Personality Inventory in a university sample and grouped participants into low, intermediate, or high Fearless Dominance groups. Participants (N = 83) were instructed to ignore distracting images (positive, negative, or neutral) in the periphery while completing a simple perceptual task at fixation. Participants low in Fearless Dominance showed greater distraction by emotional stimuli than neutral stimuli. In contrast, those high in Fearless Dominance showed no greater distraction by emotional than neutral stimuli. The findings suggest there is no fear-specific deficit in psychopathy, instead, we see an overall decrease in emotional distraction for those high in Fearless Dominance. This finding also supports attention-deficit accounts, however, distraction by neutral stimuli was not associated with Fearless Dominance indicating the reduced distraction is specific to emotional stimuli.

The sampling technique in this study was Non-Probability Sampling with purposive sampling type. The sample was 30 respondents. The instruments were interview for the history of drug breakup and patient treatment cards and observation and status of patient as the instruments of complications. Spearman Rho test results showed that value = 0.055 or more than Î± (0.05) which meant there was no correlation between the history of drug breakup with complications of tuberculosis. Based on this study, it could be concluded that the complications of tuberculosis that occur not only because of drug breakup factors but can be due to the spread of increasingly widespread germ infections, the immune system of the sufferers who are lacking, tuberculosis concomitant diseases, nutritional status of tuberculosis sufferers, and also knowledge from TB sufferers who lack the awareness to maintain health.

At the end of 2019, the COVID-19 disease emerged in the city of Wuhan, China, and caused an outbreak of unusual viral pneumonia. Being highly transmissible, this novel coronavirus disease has spread fast all over the world. COVID-19 continues to challenge most developed countries in the search for an effective strategy to either prevent infection or to avoid the spreading of the disease. While several developed countries have managed to contain COVID-19, several countries in Latin America continue to report an increase in the daily number of infected people. Ecuador, particularly, became the epicenter of the COVID-19 outbreak in the region during March and April 2020. In this context, the present study shows a simple mathematical approach to understand the effect of the COVID-19 outbreak in Ecuador (and some Latin American countries such as Brazil, Peru, and Colombia). The proposed method is based on the exponential model, discrete logistic equation, and differential logistic model using one-year data from March 1, 2020, to February 28, 2021. This study presents the estimated growth rate coefficient (λ), the total number of cases (N), and the midpoint of maximum infection (t_0) as well as the variability of the λ coefficient as a function of total cases and time. The exponential model shows a high value of λ=0.185 which decreases to λ=0.014 and λ=0.056 according to the discrete and differential logistic models, respectively. An accurate value of the total number of cases of infected people was found by analyzing the number of daily cases as a function of the total of cases whose value (N~409 K) agrees with the data reported at the end of May 2021, validating the proposed approach. How to use the current mathematical approach for long-term prediction is also discussed here. Most importantly, the proposed method has two important characteristics: (i) the mathematical model is as simple as possible compared to other time-consuming approaches, and (ii) it can be used to study the effect of COVID-19 and predicts its consequences in other countries, allowing revenue new decisions against the COVID-19 disease. Doi: 10.28991/esj-2021-SPER-09 Full Text: PDF
El Maestro. Revista de Cultura Nacional: en el origen del universo educativo y cultural vasconcelista
Authors: Enríquez Perea Alberto
Published: August 2021

El presente artículo narra y analiza uno de los aspectos más importantes de la vida de José Vasconcelos, hacer de la educación un elemento sustantivo de la vida nacional y tener los elementos para hacerla realidad. Asimismo, se rememora su pasado convencionista, sus reflexiones sobre la educación, la idea maderista que la hizo suya: con educación el hombre es libre y en libertad puede construir y defender un Estado democrático y de derecho. A Vasconcelos se le presentó con el triunfo de los sonorenses la oportunidad de llevar a cabo sus ideas y para ello, como rector de la Universidad Nacional, las impulsó para que fueran una realidad. Entre esas tareas que eran sustantivas de su pensamiento educativo estaba la creación de El Maestro. Revista de Cultura Nacional. Y como todo lo que emprendía el oriundo de Oaxaca la revista la pensaba en grande. Grande por el número de ejemplares, grande por lo que contenía, grande por su diseño y sus ilustraciones, grande por el mensaje que llevaba. La anunció como parte de su gran proyecto educativo, sin olvidar los libros de “pastas verdes”, y la concibió para que a través de ella dar a los mexicanos elementos de información y de cultura nacional y universal. Para ello reunió a un grupo de intelectuales mexicanos para que le dieran forma y contenido tal como él la había diseñado. Así pues, en torno a la revista se reunieron todos aquellos que tenían un espíritu reformista o regeneracionista, pues El Maestro. Revista de Cultura Nacional era un símbolo de esta etapa que Vasconcelos quería y ahora inspiraba e impulsaba. Colaboraban los espíritus más finos y de mayor raigambre de nuestra América y de Europa. Páginas que se rescataron o se tradujeron de los autores dilectos del educador y filósofo mexicano. Por fin se tuvo la revista y fue uno de los medios que acompañaron a Vasconcelos en esta odisea transformadora y generosa por la educación y la cultura de todos los mexicanos. En este recuento de esos días se podrá observar el ánimo y ambiente que prevalecía en esta gran cruzada por la educación pública en México.

Penggunaan baja untuk menggantikan kayu Bitti sebagai bahan konstruksi gading kapal kayu dinilai tidak praktis karena melalui proses pembentukan dan pemeliharaan, sehingga penggunaan bahan lain seperti FRP sangat penting. Penelitian ini bertujuan untuk mengetahui ukuran dan bentuk penampang bahan FRP yang sesuai sebagai pengganti gading kayu ditinjau dari segi kekuatan. Metode yang digunakan yaitu elemen hingga (FEM) dan dianalisis menggunakan metode eksperimen numerik pada software. Penelitian ini bersifat kualitatif dengan mengoptimalkan bahan FRP dengan bentuk penampang I beam, I beam+flange, box of hole beam, T beam, dan U beam+flange sebagai pengganti bahan kayu Bitti. Hasil penelitian menunjukkan gading kayu Bitti memiliki elastisitas (E) = 9534.02 MPa dan momen inersia penampang (I) = 2197x104 mm4 terjadi tegangan maksimum (?k) = 7.682 N/mm2 dan lendutan maksimum (?) = 0.1 mm, untuk faktor keamanan gading kayu Bitti (Sf) = 1.28, sedangkan bahan FRP pengganti gading kayu dengan nilai (E) = 69000 MPa dapat digunakan penampang I beam dengan nilai I = 316x104 mm4, I beam+flange dengan nilai I = 288x104 mm4, box of hole beam dengan nilai I = 317x104 mm4, T Beam dengan nilai I = 478 x104 mm4, serta U beam+flange dengan nilai I = 375x104 mm4, terjadi tegangan maksimum (?k) = 52.00 N/mm2 dengan lendutan maksimum (?) < 0.082 mm dan faktor keamanan (Sf) = 1.28. Bahan FRP pengganti kayu gading membutuhkan momen inersia penampang sebesar 1/7~1/5 kali lebih kecil dari momen inersia penampang kayu gading dengan elastisitas tujuh kali lebih besar dari kayu gading. Nilai ini dapat dijadikan patokan untuk ukuran kapal di atas ataupun di bawah 70 GT ketika akan menggunakan bahan FRP sebagai pengganti gading kayu.

Background: Delirium is an acute syndrome of organ dysfunction with long-term consequences which commonly occurs in the Intensive Care Unit (ICU). The incidence of delirium ranges from 30% - 50% in low severity ICU patients and up to 80% in mechanically ventilated patients. This condition is frequently under-recognized and daily routine screening is a key strategy to early intervention. The Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) and the Intensive Care Delirium Screening Checklist (ICDSC) are the most recommended assessment tools for detecting delirium in the critical ill patient. Objective: The main objective of this study is to educate ICU staff about delirium. In addition, nurses were trained to use the CAM-ICU as a standard screening tool. The intervention was evaluated through a survey aimed at ICU staff. Methods: An educational intervention was started in 2014 in our ICU. An educational package for ICU staff consisted of a didactic brochure and explanatory videos. One-on-one teaching, case based scenarios and didactic teaching were strategies used in the implementation process. The entire intervention was evaluated by means of a survey directed to the professionals. Results: The structure of the didactic brochure was simple in order to have an easy understanding of the CAM-ICU tool. We also created 10-minute videos. According to the results of the satisfaction survey (N=62), disorganized thinking was the most difficult feature of CAM-ICU to interpret. When in doubt, consultation between co-workers was the primary resource selected by unit staff. Conclusion: This initiative achieved the objective of training health care professionals in the application of the CAM-ICU tool with a good level of satisfaction from them. Therefore, ICU staff consider delirium management in the broader picture of critically ill patient care as a major activity of daily practice.
