Published: May 2019

El artículo reporta los hallazgos encontrados en torno a las creencias de profesores-investigadores sobre el trabajo colaborativo en la investigación del área de enseñanza de lenguas extranjeras en la Universidad Autónoma de Baja California, las cuales fueron identificadas y analizadas en una investigación de mayor envergadura que tuvo como objetivo estudiar los factores que favorecen y/o inhiben el desarrollo de la investigación en el área de las lenguas extranjeras en tres universidades mexicanas con el fin de favorecer el desarrollo institucional de la misma. Se trata de un estudio cuantitativo-descriptivo basado en un cuestionario, en el cual se identificó que los profesores creen que la investigación colaborativa favorece la cantidad y calidad de su producción académica, así como su desarrollo profesional en un ambiente que si bien contempla esta forma de trabajar no proporciona las condicionas idóneas para el florecimiento de esta actividad.
Reseña del libro La Educación Socialista en Chihuahua 1934-1940, una mirada desde la Escuela Normal del Estado, de Jesús Adolfo Trujillo Holguín
Authors: Aguirre-Lora María Esther
Published: May 2019

En esta época donde fundamentalmente se ponderan más los artículos en revistas internacionales que las obras bien pensadas, el nacimiento de un libro es un hecho digno de celebración, tanto más si éste rescata del pasado una historia digna de contar. La educación socialista en Chihuahua, 1934-1940. Una mirada desde la Escuela Normal del Estado, de Jesús Adolfo Trujillo Holguín, es una contribución seria y destacada no sólo para la historia regional de la educación en el norte del país, sino también para la historiografía chihuahuense de nuestros días y la historiografía latinoamericana de la educación.
Comparar para construir política pública en tiempos de globalización
Authors: Guzmán-León Alicia
Published: May 2019

El diseño de la política pública encarna la comparación y sistematización de la experiencia acumulada en lugares disímiles. Es el proceso que permite entender la experiencia ajena hasta llegar a la apropiación. La transnacionalización de las políticas demanda una metodología.  Si bien existen importantes aportes sobre el método comparado desde la década de los setentas, parecería “que nos hemos embarcado en una vasta empresa comparada sin tener un método comparado” (Sartori, 2011).  El halo de misterio que empapa los procedimientos y definición del método lo vuelve inaccesible. La propuesta de este artículo parte de asumir a la política pública desde una visión popperiana, donde las políticas son entendidas como  teoría, es decir, no es la ingesta o suma de observaciones sino conjeturas o hipótesis puestas a prueba en la observación, con la posibilidad de ser eliminadas o mejoradas y fortalecidas en sus puntos débiles.  De allí la relevancia de un marco de acción para la comparación.  El objetivo de este artículo es presentar al método comparado de forma integral con el fin de facilitar su implementación en la arena académica o en la política pública.  Este trabajo se divide en tres partes. La primera es la delimitación del método; la segunda sugiere un procedimiento para su implementación y finalmente; la tercera y última, establece la relevancia para el diseño y evaluación de la política pública.
Universidad y política regional en Puebla, México: 1934-1940
Authors: Márquez-Carrillo Jesús
Published: May 2019

La configuración del nuevo Estado mexicano, entre 1920 y 1940, se fincó en un sinnúmero de caudillos y caciques regionales. En Puebla se llevó a cabo durante la década de los años treinta el surgimiento y la consolidación del cacicazgo avilacamachista. El propósito del presente artículo es describir y analizar de qué manera, en este marco, se llevó a cabo el control de la universidad, una pieza más de la ingeniería que se diseñó para configurar regionalmente —y en términos sociológicos— un régimen autoritario, que no estuvo al margen del que se iba gestando en el plano nacional durante el gobierno del general Lázaro Cárdenas. Su base son entrevistas con sobrevivientes de la época, fuentes de archivo e impresas y referencias biblio-hemerográficas.

Physical and Social Perceptions of the Neighbourhood and Youth Volunteerism: Canada’s Capital Region
Authors: Pearce Sean , Kristjansson Elizabeth
Published: May 2019

Youth are embedded within various ecological systems that may impact their philanthropic behaviour. This study employed online data from a sample of undergraduate students and traced the various pathways through which neighbourhood perceptions (e.g., social cohesion, satisfaction with amenities) related to formal and informal volunteering intensities. Path analyses revealed that neighbourhood cohesion directly predicted formal and informal volunteer frequency; as well, it mediated the relationship between satisfaction with neighbourhood amenities and informal volunteerism. Neighbourhood cohesion was strongly associated with informal volunteer intensity, whereas satisfaction with neighbourhood attractiveness did not relate to any volunteer outcomes. Neighbourhood characteristics may be important drivers of youth volunteerism, and thus stakeholders, organizations, and individuals should consider the impact of the social environmental context on shaping youths’ helping behaviour.Les jeunes font partie de divers systèmes écologiques qui peuvent influencer leur comportement philanthropique. Cette étude utilise des données recueillies en ligne à partir d’un échantillon d’étudiants de premier cycle afin de retracer les divers parcours par lesquels leur perception de leur quartier (par exemple, sa cohésion sociale, leur satisfaction par rapport aux services offerts) a une incidence sur leurs activités bénévoles formelles et informelles. L’analyse révèle que la cohésion sociale a comme effet d’augmenter le bénévolat formel et informel. En outre, la cohésion semble augmenter le bénévolat informel là où il y a satisfaction par rapport aux services offerts dans la communauté. En effet, il y a une forte corrélation entre la cohésion d’un quartier et le bénévolat informel. En revanche, la satisfaction à l’égard du pittoresque d’un quartier ne paraît pas avoir d’incidence sur le niveau d’implication philanthropique. Il n’empêche qu’en général un bon quartier peut motiver les jeunes à faire du bénévolat. Ainsi, les parties prenantes, les organisations et les individus devraient tenir compte du contexte socioenvironnemental sur le comportement philanthropique des jeunes.
Methodological approaches to the assessment of state control and inspection system by the citizens as its beneficiaries
Authors: Yuzhakov V N , Dobrolyubova E I , Spiridonov A A
Published: May 2019

The success of the reform of the state control and inspection system depends significantly on taking into account the estimates of all stakeholders, i.e. business, government, and citizens as beneficiaries of the state control and inspection activities; and such estimates should be considered at the stages of planning, monitoring, and evaluating the achieved results. The priority project ‘Reforming State Control and Inspection System in the Russian Federation’ considers citizens’ estimates only if presented by statistical indicators that reflect the nature, frequency, and scale of harm often measured by the control bodies themselves, i.e. such data are prone to distortion. The authors suggest to supplement this system by indicators allowing the citizens to assess the state control and inspection activities and reform. These indicators can be measured in representative surveys, which would allow to balance the existing system of monitoring the state control and inspection activities. The article presents both international and Russian approaches to the sociological study of the efficiency of the state control and inspection system. The authors identify methodological rules of such surveys, such as that all adult citizens should be questioned regardless of their experience of interaction with control bodies. The article also describes the types of public legally protected values and the types of risks that should be part of sociological questionnaires; and suggests some key indicators for the assessment of the state control activities by the citizens: the frequency of facing the need to protect public values (the lower the frequency, the higher the effectiveness); the general estimate of the public values safety (by groups of risks); and the results of citizens’ interaction with the control bodies to protect public values including damage compensation.

Aim. To analyse and generalize available literature data on the problem of colorectal anastomotic leakage after rectal resection.

Key findings. Over the last decade, there has been an increasing trend towards sphincter-preserving operations in modern colorectal surgery. The widespread use of suturing devices of various diameters allows the formation of ultra-low anastomoses (at the level of the pelvic floor). One of the menacing complications after rectal resection is anastomotic leakage, which frequency can reach 21%. The mortality from anastomotic leakage can reach 40%. The analysed literature sources discuss a variety of risk factors, both preoperative and intraoperative, affecting the healing of the inter-intestinal anastomosis. In almost all studies, the height of the tumour and the anastomosis from the anus, preoperative radiotherapy and male sex are independent risk factors for the development of colorectal anastomotic leakage. Concerning other factors, there are conflicting opinions. The timely use of preventive measures and early diagnosis of colorectal anastomotic leakage can reduce the number and severity of postoperative complications.

Conclusion. Individual consideration of risk factors and their adequate assessment in terms of possible complications are decisive in the choice of the extent of surgical intervention, which will undoubtedly improve the immediate and long-term results of the surgical treatment of colorectal cancer.
The Nexus between Consumer Confidence and Economic Growth in South Africa: An ARDL Bounds Testing Approach
Authors: Madlopha Khayelihle
Published: May 2019

Consumption expenditure contributed a total of 2.2% to economic growth in 2017. Hence, the South African economy is consumption driven. Therefore, there is a need to understand the growth-economic confidence relationship within the South African context. In this spirit, this paper set to explore the short- and long-run relationship between consumer confidence and economic growth in South Africa for the sample period 1994Q1 to 2017Q4. The method applied, chiefly because our variables were I (0) and I (1) and that we sought short- and long-run estimates were the Autoregressive Distributed Lag (ARDL) model using the bounds testing procedure. The results showed that consumer confidence contributed about 0.025% to economic growth in the short-run, and about 0.4% in the long-run. The results suggest that boosting consumer confidence should be keys for South African policy-makers to boost growth in the short- and long-run. In particular, we recommend policy certainty and political stability as some of the ways to attract consumer confidence.

Novel succinimide derivatives were synthesized from 3-methyl-3-phenylsuccinic
acid and substituted anilines under solvent-free conditions using the
microwave irradiation. All obtained compounds were characterized by the UV,
FT-IR, 1H and 13? NMR spectroscopy as well as by elemental analysis. The
influence of the substituent electronic effects on the spectroscopic data
has been analyzed applying the Hammett equation. Moreover, a detailed
interpretation and comparison of experimentally obtained and theoretically
calculated FT-IR, UV and NMR spectra have been performed. DFT calculated
data of the investigated succinimides are obtained and analyzed in order to
determine their structural, spectroscopic and electronic properties.
Furthermore, ADMET factor profiling and in-silico prediction of potential
biological activities of novel succinimide derivatives have been performed.

Introduction. Positron emission tomography (PET) with computed tomography (CT) using fluorine- 18-labeled fluorodeoxyglucose (18F-FDG PET/CT) is a hybrid diagnostic method based on the cell?s glucose uptake detection, which correlates with the degree of disease activity. While other diagnostic procedures fail to evaluate functional tissue, 18F-FDG PET/CT can be helpful in discovering active disease in patients with vascular graft infection. Methods. This cohort retrospective study included 22 patients (17 male, five female; aged 61.7 ? 16.1) with suspected vascular graft infection. Blood analyses and CT were performed in all patients. Degree of glucose uptake was evaluated visually and semiquantitatively using maximal standardized uptake value (SUVmax). Findings were considered positive if focal fluoro-deoxyglucose (FDG) accumulation was greater in vascular graft projection than other parts of the blood vessel and liver. Results. The sighs of active disease were found in 19 patients (86%) (16 male, three female) at the level of implanted vascular grafts: six aortobifemoral (27%), four aortoiliac (18.2%), four of abdominal aorta (18.2%), two of thoracic aorta (9.1%), two femoral (9.1%), one femoropopliteal (4.5%) (SUVmax 7.9 + 2.4). Two patients were considered true and one false negative- due to antibiotic usage, which reduces FDG uptake. PET/CT helped in treatment alteration of 12 patients, seven (31.8%) started new medicament therapy, five (22.7%) had a surgical graft replacement. Overall sensitivity of this method is 95%, specificity 100%, positive predictive value 100%, negative predictive value 66.6%, accuracy 95.4%. Conclusion. 18F-FDG PET/CT is a useful diagnostic method in detection of active vascular graft infection with high diagnostic accuracy, which is important in avoiding unnecessary surgery and appropriate therapy planning.
Use of Transparent Tips for Obtaining Tight Proximal Contacts in Direct Class II Composite Resin Restorations
Authors: Alonso V , Caserio M , Darriba IL
Published: May 2019

This article describes the clinical technique of using the transparent plastic tips of the LM-Contact Former system for obtaining tight proximal contacts in direct Class II composite resin restorations using noncontoured circumferential matrix bands.

With this technique, the composite resin is pressed with the tip, which adapts intimately to the walls of the proximal box. Moreover, the total working time is reduced by filling the cavity, which remains after removing the transparent tip, with a bulk-fill flowable resin-based composite.

Published: May 2019

An objective assessment of the morphofunctional characteristics of the state of soft tissues and bone structures adjacent to the dental implant allows to control the dynamics of the processes of osseointegration in the jaw-dental implant system. The aim of the work was to investigate the level of the β-CrossLaps, С-reactive protein (CRP), osteocalcin markers after orthopedic treatment of patients using dental implant supported advanced dental restoration technologies, to perform a biochemical analysis of the oral fluid of patients after restoration using dental implants and new two-part dental implants. In patients of the index group (52 people), the removable prostheses with metal frame and fixing elements or the commercially available dental implant supported removable prostheses were installed. For the patients of the control group (12 people), the commercially available dental implant supported removable prostheses of acrylic plastics were constructed. For all the patients after 6 months the level of β-CrossLaps, CRP, osteocalcin markers in the oral fluid was analysed. In patients of the index group, the average content of β-CrossLaps was 0.0126 ± 0.002 ng/ml, in the control group it was 0.0147 ± 0.002 ng/ml. The average content of the CRP in patients of the index group was 0.358 ± 0.019 mg/l, in patients of the control group it was 0.78 ± 0.01 mg/l. In patients of the index group, the average content of osteocalcin was 1.46 ± 0.25 ng/ml, in the control group it was 1.98 ± 0.31 ng/ml. It has been shown that biochemical markers of the oral fluid can be used to predict complications after the dental implants installation. Restoration with two-part dental implants of modern design is associated with fewer complications.
A prognostic model for the prediction of generalized chronic periodontitis in patients with metabolic syndrome
Authors: Petrukhina NB , Zorina OA , Shikh EV , Kartysheva EV , Kudryavtsev AV
Published: May 2019

In this paper, we propose a model for predicting the risk of severe chronic generalized periodontitis (GCP) in patients with metabolic syndrome based on the levels of tumor necrosis factor alpha (TNF-α) in the periodontal pocket exudate. The analysis of oral cavity cytokine profiles conducted in 537 patients with GCP and comorbid metabolic syndrome showed that increased TNF-α correlated with the severity of GCP: higher levels of TNF-α were observed in patients whose condition was more severe. The prognostic model built in Statistica. 10 allowed us to use TNF-α as a prognostic criterium for GCP severity. We determined the cut-off point above which a high risk of severe GCP can be concluded with 91.2% sensitivity and 70.8% specificity. The spreadsheet in Microsoft Exсel 2010 automatically computed the risk of severe GCP from a patient’s TNF-α concentrations in the PP, which makes the model convenient for routine clinical use in dentistry.

Luto e escrita no diário de Walmir Ayala
Authors: Fortuna Daniele Ribeiro
Published: May 2019

Este artigo analisa os três volumes do diário do escritor Walmir Ayala — escritos no final dos anos 1950 e publicados nas décadas de 1960 e 1970 —, principalmente no que diz respeito à sua relação com a morte. Com uma vasta obra, atualmente pouco conhecida do grande público, Ayala lançou diversos livros, entre romances, contos, coletâneas de poesia e peças de teatro. Sua escrita é marcada por um intenso interesse pela morte. Tal interesse parece ter relação com a perda de sua mãe, que morreu quando ele tinha apenas quatro anos. Em seus escritos, o próprio escritor revela que a perda de sua mãe teve uma importância crucial na sua trajetória. Esta perda é evidente em vários trechos de seu diário. Organizado em trechos fragmentados — como é comum nesse tipo de obra —, o diário apresenta inúmeros trechos nos quais o autor trata de solidão e luto. Antes de analisar o diário, porém, apresentamos um breve resumo da vida do escritor. Em seguida, abordamos a questão da morte, explicitando como a sociedade lida com ela atualmente. Posteriormente, refletimos sobre o caráter abjeto da morte. Por fim, tratamos do diário de Walmir Ayala. Dividido em três volumes, que somam quase quatrocentas páginas, a obra revela o estreito vínculo do escritor com a morte. Como referencial teórico, são utilizadas, principalmente, as obras de Ariès (2013), Kristeva (1982) e Rodrigues (1983).
Representações de violência contra a mulher nos contos "Os negros olhos de Vivalma", de Mia Couto, e "A cabeleireira", de Inês Pedrosa

O objetivo deste artigo é problematizar a representação da violência contra a mulher na literatura contemporânea, por meio da análise dos contos "Os negros olhos de Vivalma", do escritor moçambicano Mia Couto, e "A cabeleireira", da escritora portuguesa Inês Pedrosa. Pretende-se comparar, sob o viés dos estudos de gênero, tanto na autoria feminina quanto masculina, a representação da "mulher agredida" e o posicionamento das mesmas diante das situações de violência doméstica nas narrativas em questão.
Poder e submissão em "Com açúcar, com afeto" e "Mulheres de Atenas"
Authors: Kaspari Tatiane , Saraiva Juracy Assmann
Published: May 2019

As condutas sociais da atualidade estão permeadas por relações de poder, cujas raízes se estendem no tempo. Frente a essa realidade, a ficção surge como "ato transgressor" (Iser, 1999), que pode estimular reconfigurações de papéis sociais. Sob essa perspectiva, o presente artigo analisa o processo estético de estruturação das canções "Mulheres de Atenas" e "Com açúcar, com afeto", de Chico Buarque, congregando-o à compreensão do momento da recepção do texto e do horizonte histórico de sua produção. O estudo — que considera, em especial, os pressupostos da Estética da Recepção (Jauss, 1983) — aponta que, em sua urdidura, as composições de Chico preveem um leitor ativo, atento aos não ditos (Eco, 1986) e às referências contextuais (Cortina, 2000) e, portanto, capaz de apreender a crítica sociocultural que emerge dos interstícios da enunciação lírica. Assim, transposta a camada superficial, os textos configuram-se como uma provocação séria e profunda à análise das condutas femininas e masculinas, tanto da sociedade brasileira da época de sua produção, quanto do período contemporâneo.
Ficção versus realidade: o não dito e o não visto em Branco sai, preto fica

Published: May 2019

Este artigo analisa de que maneira o filme Branco sai, preto fica (2015), do diretor ceilandense Adirley Queirós, utiliza procedimentos narrativos e audiovisuais para estabelecer uma relação crítica com a realidade, afirmando uma dimensão política capaz de contar fatos ignorados pela história, contribuindo para romper estruturas de poder que mantêm silenciado o subalterno e apresentando novas perspectivas na representação dos habitantes e do espaço da periferia. Para tanto, será utilizado o conceito de ética hacker, formulado por Mckenzie Wark, em A hacker manifesto (2004) e as reflexões apresentadas por André Gaudreault e François Jost em A narrativa cinematográfica (2009) e por Ella Shohat e Robert Stam, em Crítica da imagem eurocêntrica (2006).

Published: May 2019

Objective. Stem cell therapy, specifically, pre-induction of mesenchymal stem cells toward male germ-like cells may be useful in patients with azoospermia. The aim of this study was to evaluate in vitro differentiation of mouse bone marrow-derived mesenchymal stem cells (BMSCs) into male germ-like cells by indirect co-culture with testicular cells in the presence of bone morphogenetic protein 4 (BMP4).

Methods. Experimental groups included: control (mouse BMSCs), treatment group-1 (BMSCs treated with BMP4), treatment group-2 (indirect co-culture of BMSCs with mouse testicular cells in the presence of BMP4) and treatment group-3 (indirect co-culture of BMSCs with testicular cells). BMSCs-derived male germ-like cells were evaluated by the expression of Dazl, and Stra8 using RT-qPCR.

Results. Stra8 gene expression was significantly increased in the treatment group-2 and Dazl gene was significantly increased in the treatment group-1 compared to other groups. In conclusion, indirect co-culturing of BMSCs with testicular cells and BMP4 leads to the differentiation of BMSCs into male germ-like cells which express specific male germ-like genes. Testicular cells released factors that contributed to the differentiation of BMSCs into male germ progenitor cells.

Conclusion. This study suggests that mesenchymal stem cells may be differentiated into male germ-like cells and therefore, may be a novel treatment option for men with azoospermia.
Performance enhancement of split-phase induction motor by using fuzzy-based PID controller
Authors: Abdelwanis Mohamed I. , El-Sehiemy Ragab A.
Published: May 2019

This paper presents control and analysis of a split-phase induction motor (SPIM) to drive a centrifugal pumping system. An optimized proportional- integral and derivative (PID) controller, that is capable with a vector closed-loop split-phase induction motor control, is presented and its simulation results are discussed. The fine-tuning procedure is employed for fuzzy PID (FPID) controller parameters in order to sustain the motor speed at the predefined reference values. To assess the performance of the competitive controllers, conventional PID (CPID) and FPID, four operational indices for are suggested for measure the capability of the two controllers. These indices involve individual steady state error (ISSE) for each operating period, total steady state error (TSSE) for overall loading cycle, Individual oscillation index (IOI) and Total oscillation index (TOI), in order to measure the capability of the FPID compared with CPID. The performance of the SPIM accomplished with these performance indices is checked and tested on high and low speed levels. Pulse width modulation (PWM) based simulation studies were employed for SPIM using MATLAB/SIMULINK software. The results show that the overall performance of the SPIM operated with vector control that is tuned by FPID is enhanced compared with CPID.

In this paper, the electrical performance of double gate DG-MOSFET transistors in 4H-SiC and 6H-SiC technologies have been studied by BSIM3v3 model. In which the I–V and g
m–V characteristics and subthreshold operation of the DGMOSFET have been investigated for two models (series and parallel) based on equivalent electronic circuits and the results so obtained are compared with the single gate SG-MOSFET, using 130 nm technology and OrCAD PSpice software. The electrical characterization of DG-MOSFETs transistors have shown that they operate under a low voltage less than 1.2 V and low power for both models like the SG-MOSFET transistor, especially the series DG-MOSFET transistor is characterized by an ultra low power. The different transistors are characterized by an ultra low OFF leakage current of pA order, very high ON/OFF ratio of and high subthreshold slope of order 0.1 V/dec for the transistors in 6H-SiC and 4H-SiC respectively. These transistors also proved higher transconductance efficiency, especially the parallel DG-MOSFET transistor.

In this paper a results of a transient analysis of the linear actuator is presented. The linear actuator consist of the three cylindrical unmovable coils surrounded by a soft ferromagnetic case, a runner made from sequence of ferromagnetic and permanent magnet rings. The model of the linear actuator was implemented into two software: the Comsol Multiphysics and the Matlab-Simulink. Both environments are commonly used in simulation analysis, but the first one uses Finite Element Method (FEM) and the second one uses Ordinary Differential Equations (ODE). Moreover, the dynamic model was analysed in Matlab-Simulink software with value of electromagnetic phenomena implemented from Comsol Multiphysics. Comparison was made due to the time needed for calculation, accuracy of the simulation model as well as the as utility for further optimization process.

Conclui-se que o projeto foi essencial para a formação docente, bem como, para a concretização dos rumos profissionais de cada aluno e sua atuação ocupacional, uma vez formado. Assim, foi possível verificar que a trajetória dos egressos se constitui como um dado importante para uma reflexão sobre as ações não apenas no âmbito do programa, mas em toda a formação de professores.

Data mode “good governance” developed in the last century for process of sustainable base system, providing basic information and on-line services, supports the development, challenges and opportunities in the context of globalization and integration. In this paper I discuss a framework for the design of e-Local Governance (eLG) that integrates Information System (IS), Geographical Information System (GIS) and Atlas with focus on ethnic minorities in Vietnam. The design framework is based on various classifications such categories as sex, age, ethnic group, education background and income. The database system is built to enhance the Committee for Ethnic Minority Affairs (CEMA) capabilities in the planning and decision making process by providing the authorities with data, internet GIS, internet communication and some ecological economic models to disseminate results to the ethnic minorities. The unique feature of the CEMADATA using GIS is that it helps users not only to improve the public services and to provide information and encourage ethnic minorities to participate in decision making processes, but also to support the competency-based training for IT staff

Environmentally aware and empowered youths are potentially the greatest agent of change for the long term protection and stewardship of the environment. Thus environmental education which promotes such change will enable these youths to have a greater voice on environmental issue if effectively implemented in Nigeria. Hence, this study was conducted to assess students’ level of knowledge and attitude towards the environment. The survey was conducted on 130 respondents who were full time students of environmental education in a federal university in Edo state, Nigeria. The result revealed that high level of knowledge and positive attitude towards the environment among the students. Also it was observed that the relationship between their knowledge and attitude towards the environment is a negative, little or no relationship. Therefore, it was concluded that environmental literate students especially in tertiary institutions are being nurtured to foster EE in Nigeria. Thus the researchers recommend that more needs to be done to promote and encourage EE at all levels in the country especially by the government and its agency to ensure effective implementation; nongovernmental organizations and international bodies all have a role to play in the country sustainable development goals.
THE ROLE OF EDUCATION ON DISASTER PREPAREDNESS CASE STUDY OF 2012 INDIAN OCEAN EARTHQUAKES ON THAILAND’S
Authors: Muttarak Raya , Pothisiri Wiraporn
Published: May 2019

In this paper we investigate how well residents of the Andaman coast in Phang Nga province, Thailand, are prepared for earthquakes and tsunami. It is hypothesized that formal education can promote disaster preparedness because education enhances individual cognitive and learning skills, as well as access to information. A survey was conducted of 557 households in the areas that received tsunami warnings following the Indian Ocean earthquakes on 11 April 2012. Interviews were carried out during the period of numerous aftershocks, which put residents in the region on high alert. The respondents were asked what emergency preparedness measures they had taken following the 11 April earthquakes. Using the partial proportional odds model, the paper investigates determinants of personal disaster preparedness measured as the number of preparedness actions taken. Controlling for village effects, we find that formal education, measured at the individual, household, and community levels, has a positive relationship with taking preparedness measures. For the survey group without past disaster experience, the education level of household members is positively related to disaster preparedness. The findings also show that disaster related training is most effective for individuals with high educational attainment. Furthermore, living in a community with a higher proportion of women who have at least a secondary education increases the likelihood of disaster preparedness. In conclusion, we found that formal education can increase disaster preparedness and reduce vulnerability to natural hazards.
IMPLICATIONS OF THE FOURTH INDUSTRIAL AGE ON HIGHER EDUCATION

Published: May 2019

Higher education in the fourth industrial revolution (HE 4.0) is a complex, dialectical and exciting opportunity which can potentially transform society for the better. The fourth industrial revolution is powered by artificial intelligence and it will transform the workplace from tasks based characteristics to the human centred characteristics. Because of the convergence of man and machine, it will reduce the subject distance between humanities and social science as well as science and technology. This will necessarily require much more interdisciplinary teaching, research and innovation. This paper explores the impact of HE 4.0 on the mission of a university which is teaching, research (including innovation) and service.
Authors Response: Clinical Differences Between Children With Asthma And Rhinitis In Rural And Urban Areas
Authors: Sánchez Jorde , Sánchez Andrés , Cardona Ricardo

Dear Editors:

We greatly appreciate the interest shown in the article "Clinical differences between children with asthma and rhinitis in rural and urban areas", which we hope will be one of several future articles that we intend to carry out in the study cohort. To the questions generated by the reader, one is focused on the calculation of the sample size, while the other two questions are focus in the method of analysis, and the reader suggests, it could be more robust.

Regarding the sample size, we describe that infant asthma in urban areas of Medellin was 11% and rhinitis 23%, according to previous studies. There is no data available for the rural area. We note that with a confidence level of 95%, a power of 80% and a sample size error of 0.5%, the sample size was calculated; estimating 201 children for the urban area and 128 for the rural area. Finally, we recruited and were able to continue for a year, a total of 248 children from the urban area and 134 from the rural area. The complaint of the reader, is focus that the more appropriated technique would be "… the appropriate sample size calculation must have been the difference of means between two independent populations, although the authors did not report any ACT effect size based on previous studies." First, we fully agree with the reader that for this type of design, the study lost power by the form of sample size calculation. We did not find studies with the urban and rural ACT tests in the studied population, which made it impossible to obtain these parameters to perform the sample size calculation by the technique "power two means" (difference of means of two independent groups). ). As we noted in the article, we do not have previous data in the rural population that allow us to infer the precise prevalence of asthma in this area; as we also noted in the article the prevalence in Colombia of asthma in the general urban population is 11%, there are also data that indicate that in the child population (less than 12 years) it is around 23%; if we work with these two prevalence where we assume that the highest in children is for the urban population and that possibly the lowest corresponds to what happens in the rural population 1 and assuming the parameters; alpha 0.05, power 0.80, delta 0.12 rural prevalence 0.11 vs. urban prevalence 0.23, a sample size of 306 is required; 153 for each group; in the urban area we had the availability of 201 children and in the rural area we made 128, which is close to the desired. Therefore we consider that we fulfill the expectation according to the mathematical formula used (chi-squared test comparing two independent proportions).
Fisuras en narrativas románticas y comunidades imaginadas: María (1867) de Jorge Isaacs (1837-1895) y Úrsula (1859) de Firmina dos Reis (1825-1917)
Authors: Sañudo-Caicedo Juana
Published: May 2019

En el presente trabajo se parte del concepto comunidades imaginadas de Benedict Anderson y su relación con el Romanticismo, en las obras María de Jorge Isaacs y Úrsula de Firmina dos Reis, en las que se construyen narraciones con subjetividades resistentes al poder en términos foucaultianos. Se exploran entonces las autorías en Isaacs y dos Reis: sujetos autoriales en las comunidades imaginadas en lo que fueron los Estados Unidos de Colombia y Brasil. Así, los autores desplegarán narraciones con sujetos de enunciación limitados o con capacidad de focalizar a los afrodescendientes. Es decir que, nos enfrentamos a dos lugares de habla: el hombre blanco y hacendado en decadencia con Efraín, que, no obstante, logra contar la historia de la esclava manumisa Nay, como también la narración en tercera persona que focaliza a la esclava Susana, ambas narrativas, en todo caso, enlazadas por el relato sobre la diáspora africana.
Fernando González contra el proyecto de nación conservador. Apuntes para una lectura crítica de su obra
Authors: Castro-Toro José Sebastián
Published: May 2019

En este ensayo propongo una lectura comprensiva de la obra de Fernando González enmarcándola en en el contexto del proyecto nacional conservador enunciado en la Constitución de 1886 y desarrollado durante la Regeneración. Dentro de este marco exhibo los elementos de la obra con los que el autor construye un proyecto de nación que se opone en los puntos fundamentales al susodicho: al gramatismo mediante el lenguaje cotidiano y la lógica, al Estado confesional conservador mediante una religiosidad mística individualista, al apego al hispanismo mediante un ideal racial mestizo y al capitalismo colonial mediante una noción “comunista” de la propiedad.
