The Technology interventions have affected the agriculture production in positive manner. The Unmanned Aerial vehicles (UAVs) or drones are the latest addition in this domain. These UAVs or drones hover around in the target area and provide images of the field including crops and vegetations. Analysis of these images is done at the later stage which provides an insight into what can be done to improve the crop production. The major research areas in the use of UAVs/drones for improving the agriculture are: (1) line identification in tree orchards, (2) spraying of pesticides, (3) field data collection of various parameters like temperature, humidity etc. (4) differentiating between weeds and crop plants (5) crop health monitoring (6) harvest size monitoring (7) precision agriculture (8) smart agriculture and (9) safeguarding crop. In this paper, we listed, compared and reviewed the present research works involving drones in agriculture. This review will help to solve the farmers problems using drones and will also help in understanding the successful case studies of drones in agriculture domain.

In this research, we suggest the theory of FPHFLTSSs. This theory is combination of hesitant fuzzy linguistic term soft sets (HFLTSSs) and weights of criteria in the set namely fuzzy parameterized where all the information are given in a single set. Then, we address several related concepts and the fundamental operations of this theory, namely the addition, union and intersection. In addition, we introduce the concept of scores in FPHFLTSSs based on arithmetic mean, geometry mean, and fractional of FPHFLTSSs. Next, we introduce the concept of distance between two FPHFLTSSs based on these scores which can be used in TOPSIS approach. Three algorithms are introduced to cater some problems in algorithm discovered in previous study. The first algorithm is an easy and simple step without transforming hesitant linguistic fuzzy elements into hesitant fuzzy elements. This second approach is the extended version of Liu et al. in which they suggested their positive ideal solution (PIS) distance algorithm. For the third algorithm, we suggest FPHFLTSS's arithmetic mean distances, geometry mean, and fractional distances in TOPSIS approach. Lastly, these algorithms are used for the issue of decision making in FPHFLTSSs environment to show the feasibility and efficiency of our methods.

Digit speech recognition refers to the task of identifying the English digit spoken in a particular utterance by an unknown speaker. The conventional methods used for the recognition of digits in speech are based on robust pattern recognition techniques which deal with the statistical parameters of speech. HMM, GMM and dynamic programming techniques are some of the methods. This paper presents recognition of digits using HTK Toolkit which is based on Hidden Markov Model using MFCC. The digit speech database of this work was collected in real time from both male and female speakers and the transcription of the total collected data was done using Wavesurfer.

Drugs, also known as medicines cure diseases by interacting with some specific targets such as proteins and nucleic acid. Prediction of such drug-target interaction pairs plays a major role in drug discovery. It helps to identify the side effects caused by various drugs and provide a way to analyze the chances of usage of one drug for various diseases apart from the one disease that is predefined for that drug. However, existing Drug Target Interaction prediction methods are very expensive and time consuming. In this work, we present a new method to predict such interactions with the help of bipartite graph, which represents the known drug target interaction pairs. Information about drug and target are collected from various sources and they are integrated using Kronecker Regularized Least Square approach and Multiple Kernel Learning method, to generate drug and target similarity matrices. By integrating the two similarity matrices and known DTIs a heterogeneous network is constructed and new DTI predictions are done by performing Bi Random walk in it.

Design of optical spectral filters based on mode coupling of optical fibers is presented. The finite difference method is applied to evaluate the dispersion characteristics of optical fiber coupler which is constructed from two fibers as a composite multi-dielectric waveguide with different cores but the same cladding. Also, power and field distributions for both fibers as a separate and as a composite waveguide are investigated. The spectral characteristics of the filters are computed depending on the coupling of two linear polarized modes LP01 and LP11. The dependence of the transmission coefficient on operating wavelengths is illustrated. Finally, the spectral bandwidth of filter as a function of the distance between the two cores is addressed.

One-third of our country's income is derived from agriculture. Due to the presence of many fertile lands and deltas, India has always been one of the largest producers of food. Agriculture is the means of living for people in India. Due to many constraints, the country's revenue from agriculture is always getting decreased. These barriers include sudden rain, fire damage, and loss of crops by animals, lack of capital and proper irrigation facilities and so on. One step resolution for this problem is to innovate traditional farming with some modern technologies especially in the forest areas. Automation in agriculture helps in solving the problems in farming. Internet of Things (IoT)’s intervention in farming can give a solution so that it reduces the problems faced by farmers in our country. IoT is a framework that deals with communication between things and these things include sensors, actuators and other digital machines. The proposed system consists of smoke sensor, soil moisture sensor and ultrasonic sensor, to understand events or changes in the environment such as soil moisture level, environmental conditions like presence of fire and the presence of animals in agricultural areas and send this information for further processing. Hence proper water pumping based on the soil moisture level, sprinkling of water to control the fire damage, activation of control mechanism to prevent the entry of animals into the fields, spraying of pesticides to control pests can be done. Therefore, this system mitigates the losses in agriculture in a better way and assures that this can contribute better yields, particularly near forest areas as the possibility of destruction by animals is high.

It is known in the literature that ontology had been used extensively in machine learning for performance enhancement for text retrieval. It is also shown that robust ontology with detailed description of the domain knowledge will contribute to the accuracy in the retrieval. Nevertheless, we argue in some domain such as news text retrieval, building an ontology manually can be costly for a large-scale news repository and especially with the changes in content due to the dynamic events. In addition, maintenance can be a dauting task to keep up with new words that are associated with new events. This paper demonstrates the attempt to fully automate the development of an ontology for identifying the news domain and its subdomain. The ontology specification is defined based on the needs of the accuracy in retrieval. The mechanism of generating the ontology specification is defined and the results of the retrieval performance is discussed.

The user gives an input query in classical In-formation Retrieval (IR) system, keywords of the query are extracted and also the matching documents that contain one or more words specified by the user are retrieved. Keyword searches have a tricky time distinguishing between words that are spelled in similar way but mean something different. This often leads to hits that are completely irrelevant to the query. Se-mantic search seeks to enhance search precision by understanding searcher intent and along with the contextual significance of terms, as they seem within the searchable information space, whether on the net or within a closed system, to get more applicable outcomes. Semantically Enhanced Information Retrieval(SEIR) system can overcome the constraints of keyword based search. SEIR can semantically enhance the IR process. Therein way, searching is finished considering the meanings of query in-stead of the literal strings. Such a research automates tasks that need conceptual understanding of objects.

Background: Sero-molecular methods have been used for the study on the prevalence and economic impact of brucellosis in Bangladesh. The physio-pathological effects and therapeutic trials against brucellosis in animals or humans could not be traced in the available inland literature. Objectives: This study was conducted to determine the sero-prevalence and haemato-biochemical and therapeutic responses in Brucella-infected dairy crossbred cows. Materials and Methods: Sera samples of 552 cross-bred dairy cows of Military Dairy Farm, Jessore and smallholder dairy farms of Sirajgonj and Dhaka were initially screened for Brucella infection with Rapid kit test (RKT) and Rose Bengal test (RBT) and positive samples were tested further with ELISA and PCR for confirmatory diagnosis during the period from January 2018 to June 2019. Out of 11 all tests positive cows, of which four had history of abortion were selected for therapeutic trials with combined long acting oxytetracycline @ 25 mg/kg BW 16 doses at 72 hours intervals and streptomycin @ 25 mg / kg BW 10 doses at 24 hours interval injections. Blood samples of all the Brucella negative control and pre- and post-treatment stages of all the Brucella-infected cows were tested for haemato-biochemical changes and Brucella antibody responses by using ELISA and PCR. Results: Of the 552 sera screened for Brucella infection, of which 18 (3.26%) cows were found positive with the RKT, RBPT and ELISA, whereas only 11 (1.99%) samples showed positive with PCR. The haemato-biochemical values between Brucella-negative and positive cows and antibiotic pre-treated and post-treated values of Brucella-infected cows were compared and discussed. The antibody titer decreased with antibiotic treatment and increased on with-drawl of the antibiotic at 180 days which indicates that antibiotics only effective against bacteremic form not intracellular stage that caused to relapse. However, of the four treated cows, one became pregnant on artificial insemination with normal reproductive cycle which needs to explore its status in further research. Conclusions: The haemato-biochemical values in cows affected with sub-clinical brucellosis can determine the extent of harmful effects on the health of cows. Therapy with multiple antibiotics for long period, absence of effective vaccines and the most expensive quarantine and ‘test and slaughter’ methods, brucellosis remains as a challenge for its control and eradication in developing world. Human patients affected with brucellosis is treated with antibiotics with overall neglecting the animal reservoir of Brucella infection, therefore ‘One Health’ approach would be required to control this disease.

Authors: Samad M. A.
Published: March 2020

Background: A dozen of veterinary academic institutions offer degree courses with pre-clinical and clinical studies and conduct research works but their activities are not coordinated and unified in Bangladesh. An attempt has been made to review the pre-clinical and clinical research reports in small ruminants which would help the concerned academicians, research scientists and research funded organizations to update their knowledge of specialization and use this reference as a starting point for formulation of the future academic and research guidelines. Objectives: The main objectives are to provide an integrated, systematic overview of all the available published research reports on the pre-clinical and clinical aspects of small ruminants to update knowledge and to identify research insights, existing gaps and future research directions. Materials and Methods: The available research reports on pre-clinical and clinical aspects of small ruminants published mainly in journals during the last six decades in Bangladesh from 1966 to 2019 were reviewed. Data obtained were analyzed statistically based on pre-clinical and clinical subjects, host species, age, breeds, clinical prevalence and decade-wise to assess the rate of publication. Results: Of the 665 selected articles, 621 research papers published on small ruminants during the last six decades from Bangladesh were systematically reviewed, of which 340 (54.75%) articles reported as pre-clinical and 281 (45.25%) on clinical aspects with significantly higher rates in goats (n = 486; 78.26%) than sheep (n = 135; 21.74%). Out of 126 recorded clinical diseases and disorders in small ruminants, 125 (99.21%) reported in goats and 44 (34.92%) in sheep, with 43 (34.13%) common in both goats and sheep but only pregnancy toxaemia (0.79%) reported in sheep. The influence of age and breeds on the prevalence of clinical diseases and disorders associated with their morbidity and mortality are described and discussed. Conclusions: This unified review article would serve as a guide for the veterinary medical academicians, research scientists and organizations for future studies and research directions. The disease profiles and their morbidity and mortality status in small ruminants might help the practicing veterinarians, government, human health care providers and neighboring countries who may need to take action.

Authors: Karkarna M.Z. , Danjuma M. N.
Published: March 2020

Human benefits from wildlife are apparently declining over decades as the extent and intensity of threat to protected areas continue. This study assessed nature of community participation in wildlife management in Baturiya Sanctuary with a view to providing information for active participation of communities in the management of this area. A total of five communities namely: Shinge (4km west), Illala (12km west), Kokiro (3km east), Zigobiya (7km east) and Abanaguwa (5km north) were purposively sampled based on their proximity to the sanctuary. Snowball sampling technique was used to select fifty-seven (57) participants for the survey. Questionnaire and Interview were conducted to elicit the knowledge and perspectives of participants on the role of community in wildlife management. Numerical values were analysed in percentage while chi-square was used to test the levels of participation among communities. Findings of this study indicate that only 18 of the 57 sampled participants are involved in wildlife management. It also shows that there is decrease and extinction of wildlife especially birds, primates and reptiles in the sanctuary. The study also found four categories of participants: active-voluntary, active-institutional, passive-voluntary and passive-institutional. It shows that 37.50% active and 62.50% are passive participants respectively. Benefits of community participation include control of poaching (43.85%) and control of trade in parts of animals (25%). Majority of the participants (83.33%) engage in wildlife management voluntarily based on perceived benefits derived from the sanctuary. Poor governance (43.85%) and weak community institutions (31.57%) are the main limitations to community participation in wildlife management. This study therefore recommended that community leaders and youth should be strengthened and officially recognized as stakeholders in wildlife management and governance of natural resources in Nigeria at large.

We introduce the set of (non-spanning) tree-decorated planar maps, and show that they are in bijection with the Cartesian product between the set of trees and the set of maps with a simple boundary. As a consequence, we count the number of tree decorated triangulations and quadrangulations with a given number of faces and for a given size of the tree. Finally, we generalise the bijection to study other types of decorated planar maps and obtain explicit counting formulas for them.
Sortable Simplicial Complexes and $t$-Independence Ideals of Proper Interval Graphs
Authors: Herzog Jürgen , Khosh-Ahang Fahimeh , Moradi Somayeh , Rahimbeigi Masoomeh
Published: March 2020

We introduce the notion of sortability and $t$-sortability for a simplicial complex and study the graphs for which their independence complexes are either sortable or $t$-sortable. We show that the proper interval graphs are precisely the graphs whose independence complex is sortable. By using this characterization, we show that the ideal generated by all squarefree monomials corresponding to independent sets of vertices of $G$ of size $t$ (for a given positive integer $t$) has the strong persistence property, when $G$ is a proper interval graph. Moreover, all of its powers have linear quotients.
Group Connectivity and Group Coloring: Small Groups versus Large Groups
Authors: Langhede Rikke , Thomassen Carsten
Published: March 2020

A well-known result of Tutte says that if $\Gamma$ is an Abelian group and $G$ is a graph having a nowhere-zero $\Gamma$-flow, then $G$ has a nowhere-zero $\Gamma'$-flow for each Abelian group $\Gamma'$ whose order is at least the order of $\Gamma$. Jaeger, Linial, Payan, and Tarsi observed that this does not extend to their more general concept of group connectivity. Motivated by this we define $g(k)$ as the least number such that, if $G$ is $\Gamma$-connected for some Abelian group $\Gamma$ of order $k$, then $G$ is also $\Gamma'$-connected for every Abelian group $\Gamma'$ of order $|\Gamma'| \geqslant g(k)$. We prove that $g(k)$ exists and satisfies for infinitely many $k$,

\begin{align*}(2-o(1)) k < g(k) \leqslant 8k^3+1.\end{align*}

The upper bound holds for all $k$. Analogously, we define $h(k)$ as the least number such that, if $G$ is $\Gamma$-colorable for some Abelian group $\Gamma$ of order $k$, then $G$ is also $\Gamma'$-colorable for every Abelian group $\Gamma'$ of order $|\Gamma'| \geq h(k)$. Then $h(k)$ exists and satisfies for infinitely many $k$,

\begin{align*}(2-o(1)) k < h(k) < (2+o(1))k \ln(k).\end{align*}

The upper bound (for all $k$) follows from a result of Král', Pangrác, and Voss. The lower bound follows by duality from our lower bound on $g(k)$ as that bound is demonstrated by planar graphs.
Maximal Arcs, Codes, and New Links Between Projective Planes of Order 16
Authors: Gezek Mustafa , Mathon Rudi , Tonchev Vladimir D.
Published: March 2020

In this paper we consider binary linear codes spanned by incidence matrices of Steiner 2-designs associated with maximal arcs in projective planes of even order, and their dual codes. Upper and lower bounds on the 2-rank of the incidence matrices are derived. A lower bound on the minimum distance of the dual codes is proved, and it is shown that the bound is achieved if and only if the related maximal arc contains a hyperoval of the plane. The  binary linear codes of length 52 spanned by the incidence matrices of 2-$(52,4,1)$ designs associated with previously known and some newly found maximal arcs of degree 4 in projective planes of order 16 are analyzed and classified up to equivalence. The classification shows that some designs associated with maximal arcs in nonisomorphic planes generate equivalent codes. This phenomenon establishes new links between several of the known planes. A conjecture concerning the codes of maximal arcs in $PG(2,2^m)$ is formulated.

At first glance the two key words, assessment and autonomy in the title seemed to contradict each other. Isn’t assessment typically associated with formal learning systems and autonomy with out-of-class learning? Therefore it wasn’t a surprise to see that Benson, in his foreword, says as much when he refers to assessment as “the elephant in the room” (p. viii) in discussions about learner autonomy. The six chapters in this edited book bring the elephant out into the open. The contributors, all of them academics as well as researchers, are or have been based in Australia, Bahrain, Germany, Great Britain, Greece, Japan and the UAE. Most chapters start with the writers’ interpretations of the word ‘autonomy’ in particular, and as befits the term’s meaning, these ideas are varied. The book ends with a final list which combines references from all of the chapters, which makes sense, given that there was some overlap in sources from chapter to chapter.
On the Road to Developing a Learning Advisory Program (LAP)
Authors: Uzun Tarık , Karaaslan Hatice , Şen Mümin
Published: March 2020

Learning Advisory Program (LAP) was launched at Yıldırım Beyazıt University School of Foreign Languages in the 2015-2016 academic year. The LAP, under the guidance of the instructors and advisors at the Independent Learning Centre (ILC), was planned to be used initially with students of a specific profile, composed of low-achieving, unmotivated students – the so-called ‘repeat’ students. In our case, ‘repeat’ students pose a challenge in that teachers have difficulty identifying their individual needs, and catering for them. To address this, we enrolled these students in a partially online blended learning program. Students were also informed about the possibility of getting individual support from ILC advisors. In order to facilitate the advising sessions, new materials and tools have been devised or adapted. A few months’ experience in advising has given us a better understanding of our students and raised our motivation to turn the LAP into a more functional system.
Implementing a Language Learning Advising Service at a Self-Access Center in Cambodia
Authors: Tweed Andrew D.
Published: March 2020

This article discusses the implementation of a language learning advising service at a self-access (SAC) center in Cambodia. The SAC was opened in 2011 at a language school in Phnom Penh as a way to provide learners with additional English language learning resources and to promote learner autonomy. While it was somewhat successful in meeting these objectives, an evaluation in late 2014 revealed that the SAC’s full potential was not being realized. In particular, support for learners was lacking, and interaction in the SAC was limited. After meetings between various stakeholders, it was agreed that a language learning advising service should be implemented. This decision has resulted in a number of ongoing developments: Cambodian English teachers have been designated as advisors; they have received training in language learning advising; and learning plans have been developed. The language learning advising system was trialed for one 10-week term, and the newly trained language learning advisors (LLAs) completed surveys about their advising experience. While the responses to these questionnaires showed that LLAs generally have a positive attitude toward advising, they also revealed a number of important areas for development.
How do Learners Make Use of a Space for Self-Directed Learning? Translating the Past, Understanding the Present, and Strategizing for the Future
Authors: Nakai Yoshio
Published: March 2020

This article aims to reveal how learners make use of a space for self-directed learning to promote collaborative autonomous learning, drawing on data collected at a Japanese language institution for the Economic Partnership Agreement (EPA) care worker candidates in Osaka. The data analysis shows that, through the activities the learners chose and organized, they imagined an ideal L2 self and created their own L2 world. As soon as the self-directed learning session had started, they created their own group on Facebook and promoted learning activities which were related with their real lives in Japan. These activities on Facebook created a learning space beyond the classroom. These online activities they engaged in eventually returned to the classroom space and led to them increasingly taking ownership of the physical space. This research reveals that an important factor for self-directed learning is providing learners spaces and allowing them to explore the boundaries and possibilities of that space. The learners in this case study used the space to translate their past experiences and present emotions into the second language context, and moreover, to strategize for the future. To encourage collaborative autonomous learning, the activities must be organized around learners’ inner worlds where their emotions, experiences and futures exist.
Integrating Self-Access Center Components into Core English Classes
Authors: Mayeda Ann , MacKenzie Dirk , Nuspliger Brian
Published: March 2020

The Department of English Language and Culture at Konan Women’s University opened a self-access center in 2011. “e-space” was built into the department common room as part of a renovation project. Two full-time lecturers/learning advisors were hired to develop the language learning resources, offer advising services and to develop a more dynamic language learning community. In 2012, the department revamped its curriculum with a focus on improving the core English courses and facilitating the development of learner autonomy. Self-access language learning (SALL) activities were gradually integrated into the core courses as a way to expose students to the resources available in e-space and to provide opportunities to engage in language learning in a more learner-centered way. In 2013, teachers were asked to integrate SALL into first- and second-year core classes, and in 2014, these components became compulsory, graded sections of the courses. A stamp card system was developed to help students and teachers track the activities. At the end of the year, the cards were collected and student feedback was solicited via an online survey. While teacher buy-in has been difficult to achieve across the board, preliminary results show that the SALL components were generally successful in terms of student participation and satisfaction.
Chinos e identidad panameña
Authors: Kam Jorge

La presencia de los chinos en Panamá y su aporte al desarrollo y la consolidación de la cultura nacional panameña representan ámbitos de trabajo intelectual, investigativo y especulativo con mucha vigencia y pertinencia. Presentamos aquí los avances de un trabajo en esta materia, en pleno desarrollo. Este proyecto de investigación histórica se basa en procedimientos heurístico–hermenéuticos, empleando el submétodo etnográfico de análisis y con base en la crítica mayor de fuentes (análisis del contenido de documentos soporte de las fuentes; comparación y contrastación con el contenido de otras fuentes; y análisis de las propiedades físicas de los documentos soporte de las fuentes).
Exploración psicológica de madres adolescentes con parejas mayores que ellas
Authors: Muñoz Montserrat
Published: March 2020

Esta investigación tiene como objetivo identificar un perfil de un grupo de madres adolescentes (n=15) de la Ciudad de Panamá, cuyas parejas sentimentales son por lo menos cinco años mayor que ellas. Las participantes fueron evaluadas con el Cuestionario de Apego Adulto (Melero & Cantero, 2008). Adicionalmente, se realizaron entrevistas semiestructuradas para determinar su perfil socio-psicoló-gico y las percepciones que tienen acerca de las opiniones de otros con respecto a su embarazo y a su relación. Los resultados muestran un patrón de apego inseguro en la mayoría de las participantes. Las adolescentes perciben mayormente que su familia tiene opiniones negativas sobre su embarazo y su relación de pareja. La mayoría de estas adolescentes eligieron no utilizar métodos anticonceptivos a pesar de conocer sus beneficios. Se concluye que las adolescentes no han desarrollado las característi-cas necesarias para su maduración y toma de decisiones por lo que se han visto envueltas en situaciones de riesgo social, de salud y económicos.
Reformar la tributación para el desarrollo
Authors: Fisher Eloy
Published: March 2020

Este documento de trabajo analiza brevemente los aspectos más importantes del sistema tributario panameño, con especial atención a los ingresos recibidos en concepto de Impuesto sobre la Renta (IR) y de Impuesto de Transferencia de Bienes Muebles y Servicios (ITBMS). Asimismo, se suscriben recomendaciones sobre cómo simplificar el sistema para fortalecer su racionalidad y aumentar la re-caudación sin elevar tasas vigentes. Las fuentes de ingresos ordinarios del Estado, si bien gozan de una saludable diversificación, sufren de volatilidad tributaria, especialmente en los ingresos directos -en efecto, dos tercios de los ingresos tributarios panameños experimentan fuentes volátiles a nivel relativo. Poco más de la mitad del impuesto sobre la renta sobre personas jurídicas, que representa alrededor del 10% de los ingresos totales del Estado, está sujeto a variación frecuente. Por otro lado, del lado de los impuestos indirectos, la recaudación del ITBMS es nueve puntos porcentuales más volátil que el gasto nacional de consumo, lo que sugiere fuentes de inestabilidad propias de la recau-dación. Esta volatilidad tuvo su epicentro en las reformas fiscales sucesivas a partir de 2010, que si bien aumentaron marginalmente la recaudación, inyectaron grandes dosis de incertidumbre en el sistema tributario. Por eso, a fin de simplificar el sistema tributario nacional para dinamizar el creci-miento, se propone: 1) Iniciar gradualmente una transición del sistema vigente enfocado en rentas hacia uno de tributación de valor añadido al consumo, 2) acelerar la automatización de pagos al fisco en línea, e incentivar el desarrollo de iniciativas privadas para el desarrollo de programas informáticos de enlace, 3) subsumir el impuesto complementario y sobre dividendos sobre un impuesto sobre la renta marginal pagadero por personas jurídicas, y finalmente 4) eliminar y desfasar gastos tributarios que no tengan un objetivo claro a fin de reducir la complejidad del sistema.
José Enrique Rodó y William James, ¿Un contrapunto humanístico-filosófico americano?
Authors: USMA IPC
Published: March 2020

Este texto se ocupará de comparar dos textos el Ariel del uruguayo José Enrique Rodó (1900) y el Pragmatismo (1907) del norteamericano William James.  A través de estos textos, que no han sido comparados anteriormente, se fundaron tradiciones intelectuales americanas que hasta hoy día no han dejado de ser influyentes entre los intelectuales, el primero. Especialmente, el Pragmatismo de James se articula en una serie de textos escritos por Pierce y Dewey que, a diferencia del Arielismo, que agotó rápidamente sus posibilidades de recepción y reproducción, no ha dejado de interesar a académicos e intelectuales de todo el mundo. El objetivo de este texto es demostrar que hay similitudes entre ambas formas de pensamiento y que el Pragmatismo, tan desconocido y vilipendiado en la América hispana por ser aparentemente una ideología del Imperio y del norte, es un interlocutor perfecto para iniciar un diálogo transcultural en el continente.
