Valuing a natural gas pipeline expansion project: A copula-TGARCH application in Mexico
Authors: Massa Roldan Ricardo , Reyna Miranda Montserrat
Published: June 2020

With the liberalization of energy prices and the opening of the energy sector to competitors in Mexico, an opportunity for new investment projects is now open. Due to the current conditions of international energy markets, such as volatility and low prices with no prospect of reversion, a need for valuation tools to better capture the risk and benefits of a project presents itself. We propose a methodology based on the volatility treatment of numerous underlying assets in a Real Options Analysis: using a TGARCH for the individual volatilities and copulas for the joint effect. The methodology is applied to a natural gas distribution project of Mexico’s State oil company Petróleos Mexicanos (PEMEX). An estimated net present value of the gas pipeline is provided, considering the real options perspective. The result of our empirical application validates the real option’s theory of a higher net present value estimation for the project when incorporating the effect of different sources of uncertainty and non-linear interdependence.
Ajuste entre atributos colectivistas/individualistas del sujeto con la cultura percibida de la unidad de trabajo: Un análisis de su influencia sobre el comportamiento ciudadano organizacional
Authors: Solís Martín , Brenes Leiva Gretell
Published: June 2020

El presente estudio analiza si el ajuste entre los atributos individualistas/colectivistas de los sujetos y su percepción sobre la cultura de su unidad de trabajo influye el Comportamiento Ciudadano Organizacional (CCO).  Para el análisis se recopiló información de 248 sujetos que trabajan en una compañía transnacional. Las hipótesis se evaluaron con modelos de regresión lineal. Los resultados obtenidos revelan que los sujetos con mayor grado de individualismo horizontal ejercen mayor CCO conforme aumenta el grado de cultura adhocrática percibida en su unidad de trabajo.  También, los sujetos con mayor grado de colectivismo vertical ejercen mayor CCO conforme más jerárquica sea la cultura percibida.  La investigación aporta nueva evidencia científica, ya que anteriormente ningún estudio ha valorado si los atributos colectivistas e individualistas son más convenientes en ciertas culturas para promover el CCO. En términos de aplicabilidad práctica los hallazgos obtenidos sugieren que las organizaciones pueden promover el CCO ubicando al sujeto en unidades con culturas afines a sus características (individualistas/colectivistas).

Entre las amibas de vida libre (AVL) se encuentra el género Acanthamoeba con algunas especies
que pueden causar infecciones severas al hombre como la Encefalitis Amibiana Granulomatosa
(EAG) y la Queratitis Amibiana (QA). El principal problema en la detección de las AVL, tanto
del ambiente como de individuos infectados es el tiempo para identificarlas, que en promedio
es de tres semanas. Debido a lo anterior, es necesario implementar metodologías modernas y
confiables. El objetivo de esta investigación fue determinar la presencia de amibas patógenas
del género Acanthamoeba de cuerpos de agua de manantiales, casadas, lagunas naturales y
piscinas alimentadas con aguas termales en la Huasteca Potosina, México, utilizando el método
tradicional, así como la técnica de PCR. Se colectaron 74 muestras por duplicado, 74 se
procesaron por los métodos convencionales para detectar organismos pertenecientes al género
Acanthamoeba, el resto se analizaron por la técnica de PCR, usando el iniciador Ac6 de 195-pb.
La técnica de PCR, resultó adecuada para la identificación de amibas patógenas del género
Acanthamoeba del ambiente. La presencia de amibas del género Acanthamoeba en los cuerpos de
agua estudiados, representa un riesgo potencial de salud pública.

Estudio retrospectivo de casos de insuficiencia cardíaca en adultos del 2011 al 2015 en un Hospital Dominicano
Authors: Canahuate Grisel , Elías Purcell Marcelle , Ruiz-Matuk Carlos B.
Published: June 2020

Introducción: la insuficiencia cardíaca (IC) es un síndrome caracterizado por un funcionamiento inadecuado de las capacidades cardíacas, que se asocia con discapacidad. Sus múltiples etiologías y factores de riesgo varían geográficamente, por lo que se plantea conocer las características clínicas de la IC en la República Dominicana, con el objetivo de sugerir mejoras en los servicios de salud.

Métodos: se identificaron 2,119 casos de pacientes con IC en el Hospital General de la Plaza de la Salud (HGPS) y con base en esta población se calculó una muestra de 326 casos, a partir de un intervalo de confianza de 95 % y un margen de error de 5 %. Partiendo del cálculo de la muestra, se seleccionaron aleatoriamente 378 casos. Este sobre muestreo se realizó previendo la posible eliminación de algunos casos en los análisis finales. Luego de esto, se procedió a la extracción de datos.

Resultados: el estudio mostró que la edad promedio fue de 69 años. Se evidenciaron diversos factores de riesgos predominantes como la hipertensión arterial 87.5 %, cardiopatía isquémica 50.4 %, valvulopatías 40 %, y la diabetes mellitus un 34.7 %. También se observaron conductas de riesgo en las que predominan el uso de tabaco (23.7 %), obesidad (17.4 %) y consumo de alcohol (7.8 %). El síntoma más frecuente fue disnea con 84.7 %. La fracción de eyección promedio fue 48 %. El tratamiento más común fue los diuréticos. La mortalidad registrada fue 11.1 %.

Discusión: este estudio evidencia una alta ocurrencia de conductas y factores de riesgo, cuya intervención y subsecuente disminución pudiera significar cambios importantes a la prevalencia de la IC en el país.

El triaje busca identificar a aquellos pacientes que necesitan atención inmediata y a los que pueden esperar con seguridad durante un tiempo más prolongado. Se realizó un estudio observacional, descriptivo y prospectivo, con pacientes que acuden al servicio de emergencias del Hospital Infantil Dr. Robert Reid Cabral en los meses de septiembre, octubre y noviembre de 2018, para un total de 32 %, 21 %, y 47 %, respectivamente. El total de pacientes captados fue 660, 54 % masculinos y 46 % femeninos. Edad de mayor asistencia de 1-6 años, 311 para un 47 %. El 4to nivel fue el de mayor atención, 219 para un 33 %. Mayor flujo horario de 11:00 a.m. a 4:00 p.m., para un 5.8 % y 6.1 %. Tiempo de respuesta nivel 1: 50 seg; nivel 2: 22 min con 5 seg; nivel 3: 41 min con 12 seg; nivel 4: 49 min con 35 seg; y nivel 5: 48 min con 53 seg. Como conclusión, la respuesta a las atenciones se ve afectada por la falta de triaje estructurado, una respuesta más rápida y oportuna a pacientes con niveles 3 a 4, gracias al alto volumen de pacientes que acuden y no así a los de nivel 1 y 2.

Published: June 2020

The current study is aimed at evaluating the reaction of winter wheat varieties according to cultivation technologies at a different level of intensity i.e. basic, intensive and high intensive. The cultivation technologies included fertilizers, pesticides and growth regulators at different combinations and concentrations. The experiment was established in order to determine the optimum conditions of winter wheat cultivation. Three winter wheat varieties were studied: Moskovskaya 40 (V1), Nemchinovskaya 17 (V2) and Nemchinovskaya 85 (V3). Yield performances and grain quality (measured through protein and gluten content) were determined according to the tested cultivation technologies. The results showed that the cultivation technology affected grain wheat productivity and quality on all varieties studied, since the highest yields were obtained using high intensive cultivation technology for all varieties studied, Moskovskaya 40 - 9.65 t/h, Nemchinovskaya 17 - 8.58 t/h and Nemchinovskaya 85 - 9.87 t/h. However, according to the basic technology, the yield was lower by 2064 %. The tested cultivation technologies demonstrated that high intensive cultivation technology increased wheat quality. The highest protein content (18 %) was recorded in Nemchinovskaya 85 variety. The present results give real opportunities for a largescale application of the tested cultivation technologies in different agricultural lands of Russia.
Fuzzy logic device for crop analysing, modeling and forecasting in the Kabardino-Balkarian Republic
Authors: Bischokov Ruslan M.
Published: June 2020

Using computer fuzzy-logical models based on empirical values of climatic characteristics (rainfall, temperature and humidity) of long-term observations (1955-2018) from meteorological stations in the Kabardino-Balkarian Republic (Nalchik, Baksan, Prokhladny and Terek) and crop yields (winter wheat, spring wheat, corn, sunflower, millet, oats), dependence of crop yields on variations of climatic factors were analyzed and a specific forecast was given. Setting expected values of climatic characteristics in computer model, we received possible values of productivity for the next season. Uniformity assessment (Dixon and Smirnov - Grabbsas criterion), stability (Student and Fischers criterion), statistical importance of parameters of distribution and accidental errors were determined. Originality of the method is in the fact that in the form of input parameters of the model predictors, the previously calculated forecast values of the meteorological parameters for the next agricultural year were used, and at the output, the predicted values of crop productivity were obtained as predictants. Furthermore, recommendations on adoption of management decisions were developed.

Authors: Naserzadeh Yousef , Pakina Elena N. , Nafchi Abdorreza M. , Gadzhikurbanov Anvar Sh.
Published: June 2020

D. melanogaster is one of the most harmful citrus fruit flies having a large number of host plants. The molecular diagnostic method has been created for identification the D. melanogaster from another non-quarantine species Drosophila spp. The proposed method for differentiation is to use the mitochondrial DNA cytochrome oxidase I gene region 709-bp. We amplified samples of DNA with primers Droso-S391 and Droso-A381 by D. melanogaster, D. suzukii, and D. Simulans collections in the laboratory samples from many countries and contrasted with sequences of other GenBank Drosophila taxa. The findings of a polymerase chain reaction (PCR) based on DNA sequence polymorphisms showed that these primers accurately identify the area of the gene as well as the unique primers of Drosophila melanogaster.

Published: June 2020

The rate of sarcocystosis detection in slaughtered cattle was studied. The infection rate for slaughtered animals averaged 0.382.11 % of studied livestock. The location of sarcocysts in various muscle tissues of the carcass was determined. Organoleptic, physical chemical and microbiological characteristics of beef from sick and healthy animals were compared. Detected was a decrease in sensory indicators by 0.140.34 points, an increase in pH - by 0.34 units, an increase in VFA - by 0.4 mg/KOH and in amino-ammonia nitrogen concentration - by 0.09 mg/%. The content of protein decreased by 0.92 %, fat - by 1.04 %, and moisture level increased by 2.90 %. At the same time, a decrease in relative bioavailability by 10.7 % and safety by 5.1104 of meat infected with sarcocystosis as compared to meat of healthy cattle was detected. It was found out that the shelf life of chilled meat from animals infected with sarcocystosis is 1-2 days less than that of healthy ones. Based on the data obtained, proposals were developed for improving the veterinary-sanitary evaluation of meat and other products of slaughtered animals infected with sarcocystosis in order to be incorporated into the Rules of Veterinary Sanitary Examination of Meat and Meat Products.
The history of the Notion of the State in West Africa: from the destruction of empires to the emergence of the modern state resulting from colonization (the case of the Mali Empire)
Authors: Camara Sidy
Published: June 2020

This article aims to address the question of the emergence of empires in West Africa from the ninth century to the present day. The author plans to make an in-depth analysis of the political formation of the different empires which have succeeded each other in this vast West African space which nowadays shelters the current republics of Mali and Mauritania in particular and in general throughout other West African countries (Guinea, Senegal, Ivory Coast, Gambia, Burkina Faso, Niger). The largest and most famous empires that appeared on the territory of what is now Mali is called the Ghana Empire in the 9th century and was succeeded by the Mali or Mandé Empire in the 13th century. The influence of these empires throughout Africa and the rest of the world shows us a particular interest in understanding over time the notion of the State in Africa before the colonization and destruction of the African political system and its replacement by colonial state with the arrival of Europeans. Today the question of the weakness of the modern or postcolonial state in Africa and Mali poses many questions not only in the concert of nations but also in the academic and university environment. We will try to demonstrate in this article the link between the break in the evolution of the African state and the imposition of the modern European state through the colonial state which is at the root of the backwardness of African countries in terms political, economic and social compared to the rest of the world.

Published: June 2020

Museums are one of the most complex institutions of our time, which concentrate the implementation of many functions. One of them could be described as the formation of historical memory. The implementation of this function is associated with many aspects of a heterogeneous nature. The purpose of this article is to reveal these aspects. What was written in this article should be primarily attributed to historical museums, since they are precisely those institutions that are most closely interconnected with the concept of historical memory and historical knowledge. The aspects of historical memory formation discussed in this article will be described in the memory studies paradigm.

African International Relations, Genocidal Histories and the Emancipatory Project. Part 2
Authors: Campbell Horace G.
Published: June 2020

Silences in the discipline of International Relations on genocide amount to a form of genocide denial, which is one of the foundations of future genocide. The paper posits that in the era of militarized global apartheid, progressive scholars are challenged to critique and expose the past and current crimes against humanity that are occurring in Africa. Drawing from the consolidation of an alternative analysis in the context of the Bandung Project, the paper analyzed the contributions of the ideas that emerged out of the anti-apartheid struggles and the struggles for reparative justice. Struggles from the Global South had culminated in the World Conference against Racism (WCAR) process, elevating the anti-racist battles as a core challenge of Africas International Relations. This rejuvenation and energies coming out of the protracted struggle for bread, peace and justice took the form of the transition to the African Union leaving behind the concept of the noninterference in the internal affairs of states. The paper analyzed the ways in which afro-pessimism was being reinforced by the constructivist path in African International Relations. The contributions of radical African feminists are presented as one new direction where there is the coalescence of the progressive anti-imperialist intellectual traditions with radical feminisms. These two traditions open possibilities for an emancipatory project. This project has taken on extra importance in the period of the fragility of global capital when the precariousness of capitalism threatens new and endless wars and destabilization in Africa. Modern humanitarianism forms one component of the weaponization of everything and it is within this ensemble of ideas that scholars need to deconstruct the discussion of failed states in Africa.

THE DUALISTIC MODEL AND “RATIONAL CENTRALIZATION” AS FACTORS OF THE EFFECTIVE FUNCTIONING OF LOCAL GOVERNMENT WITHIN THE RUSSIAN PUBLIC AUTHORITY MECHANISM
Authors: Chikhladze Levan T. , Larichev Aleksandr A.
Published: June 2020

The analysis is given on the correlation of state power and local government within the public power system of Russian Federation. The authors note that the interaction of relevant elements can be described as a dualistic model, based on a combination of centralization and decentralization principles. It is maintained, that the principle for interaction between state authorities and local government, especially in light of recent constitutinal amendments, should rest in clear delineation of functions and powers, excluding their arbitrary and unreasonable redistribution. It is also noted that for the effective functioning of local government, interaction between central and local authorities is important, based on the support of the latter by the state. State intervention implies the concept of rational centralization, which envisages strengthening state role in the implementation of both organizational and functional foundations of local government in strictly limited cases and without violating Art. 12 of the Russian Constitution.
BEHAVIOURAL SUPERVISION OF THE BANK OF RUSSIA IN PROTECTION OF FINANCIAL SERVICES CONSUMERS' RIGHTS
Authors: Mikheeva Irina V. , Dolkova Elizaveta A.
Published: June 2020

The article is devoted to a new type of supervision of financial market participants - behavioral supervision of the Bank of Russia. Behavioral approach to the protection of financial services consumers rights is treated in the zone of action of the administrative-legal regulation mechanism. The authors point to the public nature of the subject composition of its implementation (the Bank of Russia and the executive authorities); the possibility of using the judicial (consideration of citizens' appeals) and (as a result) jurisdictional (bringing the violators of the financial services consumers rights to administrative responsibility) procedural administrative and legal algorithms. The article outlines the types of the behavioral supervision regime of the Bank of Russia. Reactive behavioral supervision is a reaction of the Bank of Russia to complaints or received information about unfair behavior of the financial company towards the consumer. Preventive behavioral supervision is associated with the prevention of serious violations of citizens rights by supervised organizations. Particular attention is paid to consumer risks, the identification of which is one of the goals of behavioral supervision. Supervisory behavioral aspects are closely associated with the financial consumer protection as an important part of the control and supervising activity of the Bank of Russia. Also, the authors analyze the goals and content of behavioral approach to the financial management aimed at minimizing unfair practices. To gain the aim of the research the authors apply general scientific methods (synthesis and analysis, induction and deduction, generalizations) and special methods (formal-legal method). By using general scientific methods and formal-legal method authors investigate the organizational and legal basis for the implementation of behavioral supervision in Russia and determine its advantages and disadvantages. The study expresses assertion that there is the need to place behavioral supervision in the legislative framework, to formulate a definition of behavioral supervision, to clarify the scope and powers of the subjects of its implementation, to determine the content of administrative procedures for the implementation of various types of behavioral supervision within the framework of the interaction of the Bank of Russia and the executive bodies involved in its implementation.
THE LEGAL STATUS OF A LAWYER IN THE RUSSIAN FEDERATION AND THE REPUBLIC OF KOREA: COMPARATIVE-LEGAL ANALYSIS
Authors: Dobryakov Denis A.
Published: June 2020

Corporations of attorneys-at-law (in Russian this term is a synonym to advocate and similar to lawyer; it means a legal professional who passed qualification exam and obtained special status of a lawyer) in the Russian Federation and the Republic of Korea passed complicated historical way and now have many common and even universal features, though circumstances of their forming were completely different. In both Russia and Korea lawyers are members of one of the most significant civil society institutions, which protect rights of their citizens, seeking legal advice or receiving such advice by other means (for example, when a lawyer was designated by investigator in the Russian Federation). Attorneys-at-law face challenges in their qualification and practical experience. Candidates for the status must pass a special test (the qualification exam), but there are some exceptions. One of the important differences is Korean law on the bar and lawyer activities regulated by the Russian legislation. If in Russia every candidate for lawyer's status must pass qualification exam without any exceptions in terms of experience and previous employment, in the Republic of Korea former prosecutors and judges have privileged position and are exempted from the examination as appropriate level of their qualification is presumed. At the same time, in the Russian Federation a candidate for lawyer's status is a priori jurist what means that he must have higher education in the field of law, while in the Republic of Korea access to the attorneys corporation in open to everyone regardless of the level and profile of education. However, non-jurist candidates must pass a bar exam. This article provides a comparativelegal analysis of the development and modern regulation of the legal status of a lawyer in the legislation of the Russian Federation and the Republic of Korea, examines both the differences of the legislation of the named countries, as well as common features. Besides this study is one of the first in the Russian legal science with reference to the Korean bar.
DEVELOPMENT OF THE INSTITUTE OF QUALIFIED LEGAL ASSISTANCE IN RUSSIA AND THE FORMER SOVIET UNION
Authors: Gavrilova Anzhelika V.
Published: June 2020

The relevance of this work is due to the modern processes of regulation of the legal services market, typical both for Russia and for sovereign States in the post-Soviet space, in order to ensure the constitutional right to qualified legal assistance. The purpose of the work is predetermined by the analysis of ideas about qualified legal assistance in a retrospective and modern sense. The research was based on normative legal acts, including monuments of law, and scientific works (academic publications, monographs) devoted to the development of legal aid. The study was carried out using a set of comparative legal methods: the diachronic method allowed us to compare the basics of legal aid that existed in different historical periods; the synchronous method made it possible to compare the legal reality of Russia with other countries. The problem-chronological method allowed to study the essential features of the evolution of ideas about legal aid that are directly dependent on the socio-cultural transformations of the political and legal system of the and interpretation of norms, implementation of which determines the modern processes of professionalization of legal aid. The study of pre-revolutionary legislation of Russia allowed us to conclude that the traditional understanding of the provision of professional legal assistance by lawyers is formed in the process of socio-cultural modernization of the legal system during the implementation of the Judicial reform of 1864. the Paradigm of legal nihilism in the first years of Soviet power resulted in lacking any qualification requirements for persons who can provide legal assistance, which predetermined the stable practice of lawyers who did not have professional education. The liberalization of legislation during the thaw period contributed to the return to traditional understanding of legal aid. The regulation of legal aid in modern States is carried out in line with the implementation of international standards in national legislation.

Effects of Vitamin D Supplementation on Prevention of Type 2 Diabetes in Patients With Prediabetes: A Systematic Review and Meta-analysis
Authors: Zhang Yu , Tan Huiwen , Tang Jingjing , Li Jing , Chong Weelic , Hai Yang , Feng Yuning , Lunsford L. Dade , Xu Ping , Jia Desheng , Fang Fang
Published: June 2020

BACKGROUND

While observational studies have shown an association between vitamin D insufficiency and diabetes, it is unclear whether intervention with vitamin D supplements can lower the risk of type 2 diabetes mellitus (T2DM).

PURPOSE

To assess whether vitamin D supplementation reduces the risk of T2DM in people with prediabetes.

DATA SOURCES

We searched MEDLINE, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL) from inception to 5 July 2019.

STUDY SELECTION

We included randomized controlled trials assessing vitamin D supplementation versus placebo in relation to new-onset T2DM in people with prediabetes.

DATA EXTRACTION

We screened studies and extracted data from published trials independently.

DATA SYNTHESIS

We identified eight eligible trials with a total of 4,896 subjects. Vitamin D supplementation significantly reduced the risk of T2DM (risk ratio [RR] 0.89 [95% CI 0.80–0.99]; I2 = 0%). Benefit was found in nonobese subjects (RR 0.73 [95% CI 0.57–0.92]) but not in obese subjects (RR 0.95 [95% CI 0.84–1.08]) (Pinteraction = 0.048). The reversion of prediabetes to normoglycemia occurred in 116 of 548 (21.2%) participants in the vitamin D group and 75 of 532 (14.1%) in the control group. Vitamin D supplementation increased reversion rate of prediabetes to normoglycemia (RR 1.48 [95% CI 1.14–1.92]; I2 = 0%.)

LIMITATIONS

Definitions of prediabetes and new-onset diabetes in eligible studies were different, and long-term data on outcomes of T2DM prevention were lacking.

CONCLUSIONS

In persons with prediabetes, vitamin D supplementation reduces the risk of T2DM and increases the reversion rate of prediabetes to normoglycemia. The benefit of the prevention of T2DM could be limited to nonobese subjects. Individual participant data meta-analyses are needed to confirm these findings.
Significant features characterizing the nature of varicose vein disease
Authors: Recek Cestmir
Published: June 2020

The following features characterize varicose vein disease: 1) Venous reflux, 2) Inherent weakness of the vein wall, 3) Tendency to recurrence. Venous reflux is the most important pathological hemodynamic phenomenon causing ambulatory venous hypertension and evoking chronic venous insufficiency; it is released by the ambulatory pressure gradient, which arises during calf pump activity between thigh and lower leg veins. Inherent weakness of the vein wall entails increased vein distensibility. The impaired vein wall structure is not able to resist the dilatation force of the hydrostatic and intra-abdominal pressure; the veins in the lower extremity subsequently dilate, become incompetent, and tend to form varicose veins. Abolition of saphenous reflux removes the hemodynamic disturbance but it simultaneously generates preconditions for reflux recurrence. This run of events is triggered by the drainage of venous blood from the thigh saphenous system into deep lower leg veins, which occurs during calf pump activity. The dividing line of the ambulatory pressure gradient that is located in healthy people just below the knee joint is displaced into the thigh between the femoral vein and the incompetent thigh saphenous system; in this way, pressure gradient between the femoral vein and the incompetent saphenous system occurs and starts the chain of events that evokes reflux recurrence. Hindrance of the untoward drainage at the knee level would prevent generation of this prerequisite for reflux recurrence.

GENERISANJE SLIKA SA VIŠE OZNAČENIH MNIST CIFARA UPOTREBOM GENERATIVNIH NEURONSKIH MREŽA
Authors: Maletin Luka
Published: June 2020

Za treniranje generativne neuronske mreže za generisanje slike već postoje ustaljeni šabloni i principi, ali trenutna istraživanja bave se pre svega generisanjem slike sa jednim objektom. Generisanje slike sa više željenih objekata koji se nalaze na određenim pozicijama, i koji su u koheziji sa pozadinom, značajno bi proširilo primenu ovakvih modela. U ovom radu predstavljena je arhitektura modela za generisanje slike sa više označenih cifara na jednostavnoj pozadini. Kao ulaz modela prosleđuju se labele i granični okviri cifara koje je potrebno iscrtati. Istrenirani model uspešno generiše slike sa redosledima cifara koje je video tokom treniranja, a u slučaju novih redosleda ne generiše uvek očekivane cifre. Predloženi su koraci za poboljšanje i dalji razvoj arhitekture.

MULTI-FACTORIAL PATTERNS OF ONLINE HOMEWORK USAGE IN ENGINEERING: A PILOT STUDY
Authors: D’Entremont Agnes , Verrett Jonathan , Hu ShunFu , Abelló Juan , Harandi Negar M. , Leonzio Tyler , Chan Wan Fong Warren
Published: June 2020

WeBWorK online homework usage data for a second-year, 130-student mechanical engineering course was analyzed using latent profile analysis (LPA) to identify student usage patterns and their relation to tests/exams grades. Ten WeBWorK usage variables were used by LPA to identify three distinct student sub-groups having particular usage patterns. The resulting three sub-groups were found to have statistically significant differences in tests/exam grades. Lower grades corresponded to fewer WeBWorK sessions and questions attempted, with a higher number of attempts and questions attempted per session; lower grades also corresponded to lower collaboration metrics and later first submissions of correct answers. These results might be used by instructors to inform and encourage online homework usage practices that are related to higher grades.
STUDENTS’ PERSPECTIVE: DOES PROBLEM-BASED LEARNING INCREASE OWNERSHIP OF ONE’S EDUCATION?
Authors: Ghaemi Roza Vaez , Potvin Gabriel
Published: June 2020

Students in the 4th year laboratory course in the Department of Chemical and Biological Engineering (CHBE) at UBC perform multi-week problem-based laboratories (PBL). Open-ended industrially-relevant problem statements are provided as context, but teams are not bound by them and can choose alternative problems according to their interests. Operating instructions for equipment are provided, but students must develop their own experimental designs and data collection and analysis protocols. TA involvement is greatly reduced compared to previous courses to promote independence and self-reliance. In previous work, students indicated that this approach helped them develop their critical thinking and problem-solving skills, and increased their confidence in their engineering abilities. Anecdotal evidence and an analysis of the survey data in that study suggest that one possible reason for the benefits outlined above stem from students’ imposed self-reliance and ownership of their work, coupled with a freedom to experiment with no consequences for failure.       To explore this question, a questionnaire was sent to the current cohort of students, asking them to qualify their enjoyment of the course (level of enjoyment, workload, perceived relevance), the effectiveness of the course (perceived knowledge and skill development), as well as their perceived level of agency in the course (perceived freedom and autonomy regarding content and research direction). Students were then invited to a focus group to further elaborate on the course and reflect on their overall experience during the undergraduate studies, whether they felt they had agency or ownership during their studies, and whether they believe problem-based learning should be implemented in other courses earlier on in the program. Responses were thematically analyzed, and are presented in this paper.

Published: June 2020

El presente estudio correlacional, de campo y diseño no experimental tuvo como objetivo determinar la correlación entre el afrontamiento, el funcionamiento familiar y la calidad de vida relacionada con la salud en una muestra de cuidadores de pacientes oncológicos venezolanos. Participaron 200 cuidadores de ambos sexos, con edades de 18 a 82 años, de pacientes oncológicos que asistían a dos centros especializados en oncología en la ciudad de Caracas, a quienes se aplicó el cuestionario SF-12, la Escala de Estilos de Afrontamiento y la escala FACES-III de funcionamiento familiar. Los resultados mostraron una correlación directa entre los estilos de afrontamiento racional y por desapego con la cohesión y adaptabilidad familiar. El funcionamiento familiar y el estilo de afrontamiento no correlacionaron con la calidad de vida relacionada con la salud de los cuidadores, excepto el estilo emocional, que tuvo una correlación inversa y significativa.

Published: June 2020

El objetivo del presente estudio fue evaluar la efectividad de un programa dirigido a padres de jóvenes con discapacidad intelectual para promover la comunicación con sus hijos sobre temas relativos a la sexualidad. El programa se diseñó con fundamento en los conceptos de autoeficacia y aprendizaje estructurado. Participaron cinco padres, cuya edad promedio fue de 43 años, con hijos con síndrome de Down o con otro tipo de discapacidad intelectual, con edad promedio de 18 años. Se utilizó un diseño n = 1 y se recabó información antes de la intervención, al finalizar ésta y transcurridos tres meses, sobre las variables de autoeficacia, expectativas y comunicación sobre sexualidad. El programa de intervención tuvo una duración de diez sesiones. Los resultados indican que, desde la fase de pretest, la mayoría de los participantes reportaron tener expectativas positivas hacia la comunicación; después de la intervención, todos ellos reconocieron los efectos positivos de la comunicación. Resultados similares se obtuvieron en cuanto a la autoeficacia percibida para hablar con sus hijos sobre todos los temas de sexualidad incorporados al programa. Los mayores efectos se observaron en el número de temas abordados porque se logró que, en la fase de seguimiento, todos los padres mantuvieran comunicación con sus hijos sobre todos los temas abordados en el taller. También se observó un aumento en el número de habilidades conductuales desarrolladas por los hijos de los participantes. Al tiempo que se concluye que el programa fue eficaz para lograr su objetivo, se discuten las aportaciones y limitaciones del estudio.
