Published: July 2020

En México hay gran diversidad de papas (Solanum tuberosum L.), pero este rico recurso genético no se utiliza como debiera debido a la escasa información genética existente. Un análisis de datos consenso de RAPD e ISSR se utilizó para estudiar la diversidad genética y estructura poblacional en quince cultivares de papa (9 mejorados de Europa, Estados Unidos de América y México, y 6 criollos mexicanos) sembrados en México. Las amplificaciones con 5 iniciadores decámeros al azar y 5 iniciadores ISSR generaron 138 bandas de las que 116 (84.4 %) fueron polimórficas. El coeficiente de similitud más alto (0.89) se detectó entre los cultivares Fianna y Armada. En contraste, el coeficiente de similitud más bajo (0.55) se obtuvo entre Tollocan y Cambray Rosa Morelos. El alto nivel de diferenciación genética entre cultivares (GST = 0.71) y bajos valores de flujo genético (Nm = 0.19) a través de todos los loci indicaron que el nivel de divergencia genética entre los 15 cultivares es alta. El análisis de varianza molecular reveló una contribución significativa de las diferencias entre regiones, entre cultivares, entre y dentro de las poblaciones, a la diversidad genética total de los cultivares estudiados.

Published: July 2020

En México, la vainilla (Vanilla planifolia Jacks.) es considerada una especie endémica sujeta a protección especial debido a las severas afectaciones que ha sufrido su hábitat natural. En atención a esta problemática, es importante emprender programas para el rescate y conservación de este valioso recurso genético. El objetivo de este estudio fue evaluar el efecto de cuatro concentraciones (0, 10, 20 y 30 g L-1) de dos agentes osmóticos: manitol y polietilenglicol (PEG), y cuatro concentraciones (0, 1, 2 y 3 mg L-1) de dos inhibidores del crecimiento vegetal: ácido abscísico (ABA) y paclobutrazol (PAC), sobre la supervivencia y crecimiento in vitro de plantas de V. planifolia. En todos los tratamientos se utilizaron brotes de 0.5 cm de altura regenerados in vitro. Estos brotes fueron cultivados en medio de cultivo (MS). A los 180 d de cultivo se evaluó porcentaje de supervivencia, longitud de la planta, número de hojas, número y longitud de raíces. Los cultivos in vitro mostraron valores menores en las variables evaluadas de crecimiento, cuando fueron incrementadas las concentraciones de los agentes osmóticos e inhibidores en el medio de cultivo. Los tratamientos con PAC mantuvieron 100 % de supervivencia de los brotes. Sin embargo, este compuesto provocó la presencia de anormalidades en la parte apical y radical de las plántulas in vitro. Respecto al ABA, al utilizar 3 mg L-1 los brotes mostraron valores menores en todas las variables evaluadas y 90 % de supervivencia. Estos resultados permitieron establecer un método de conservación in vitro a mediano plazo de V. planifolia que prolonga el periodo entre subcultivos cada 180 d, sin afectar la viabilidad y fenotipo de las plantas.

En la región de el Bajío en el centro de México, el rendimiento del garbanzo (Cicer arietinum L.) es limitado por enfermedades de la raíz como la marchitez vascular causada Fusarium oxysporum f. sp. ciceris (FOC). El conocimiento de las razas existentes de este patógeno permitirá usar los cultivares resistentes apropiados. El objetivo fue identificar las razas de FOC existentes en El Bajío, estado de Guanajuato por medio de marcadores moleculares específicos. Se analizaron aislados provenientes de cinco municipios productores de garbanzo (Celaya, Salvatierra, Valle de Santiago, Huanímaro y Pénjamo). Se probaron 12 iniciadores, siete de secuencia arbitraria tipo RAPD (OP1-01, OPI-09, OPI-18, OPF-06, OPF-10, OPF-12 y OPF-16) asociados a las razas 0, 1A, 1B/C, 2, 3, 4, 5 y 6 de F. oxysporum f. sp. ciceris, y cinco de secuencia tipo SCAR (FocR0-M15, FocR1B/C-N5, FocR5-L10, FocR6-O2, FocR6-P18-FocR0-M15), procedentes de los fragmentos marcadores raciales tipo RAPD inicialmente identificados. Los marcadores señalaron la presencia de cuatro razas: 0, 1B/C, 4 y 6, de FOC; las razas de mayor frecuencia fueron la 0 y 1B/C, que inducen el síntoma de “amarillamiento”, y la raza 6 que induce el síntoma de marchitez. Con las razas identificadas en Guanajuato y la raza 5 aislada en el estado de Sinaloa, se realizó una prueba de patogenicidad sobre las líneas diferenciales: JG 62, Sanford, P 2245, CRIL 1-53, CRIL 1-94, CRIL 1-17, CRIL 1-36, y WR 315, por el método de inmersión de raíces. Los resultados de la inoculación verificaron la identificación de razas con los marcadores. Las diferenciales resistentes fueron CRIL 1-36, WR 315, y CRIL 1-17, las que pueden utilizarse como progenitores en el mejoramiento de la resistencia contra FOC en México.

Authors: GÜLTEKİN Nurullah
Published: July 2020

Otomobillerin konforunu etkileyen en önemli faktörlerden birisi gürültüdür. Gürültünün insan sağlığı üzerinde; stres, dikkat dağınıklığı, baş ağrısı gibi olumsuz etkileri bulunmaktadır. Bundan dolayı alıcıların otomobil alırken tercihlerini etkileyen unsurların başında ses yalıtımı gelmektedir. Üreticiler otomobilleri daha sessiz yapabilmek ve konforu artırmak için birçok yeni tasarım geliştirmektedir. Bu tasarımlar otomobillerin oluşturduğu ses seviyesini oldukça düşürmüştür. Fakat oluşan sesleri tamamen ortadan kaldırmak günümüz koşullarında imkansızdır. Tasarımcılar sesleri tamamen ortadan kaldıramadığından dolayı konforu artırmak amacıyla, aracın oluşturduğu seslerin kabin içine girmesini önlemeye yönelik çalışmalar yapmaktadır. Seslerin kabin içerisini girmesini engellemek için otomobillerde ses yalıtım malzemesi kullanılmaktadır. Lastik sürtünmesi veya rüzgar gibi etkenlerin oluşturduğu sesleri yalıtım yapmak için ise araç çamurluklarında davlumbazlar konulmaktadır. Kullanılan davlumbazlar dış ortamdaki seslerin kabin içine gelmesini önlemekte oldukça etkilidir. Özellikle stabilize yollarda ve yağışlı havalarda davlumbaz kullanımı, araç içi ses seviyesini oldukça düşürmektedir. Çalışmada; standart bir otomobildeki davlumbazın, farklı hızlarda ve farklı hava koşullarında ses yalıtımına etkisi deneysel olarak incelenmiştir. Otomobil içerisinde ses ölçümleri yapılarak davlumbazda uygulanan değişikliğin gürültüye etkisi tespit edilmiştir. Deneylerin bazıları değerlendirildiğinde; davlumbaz üzerine 100x100 mm açıklık bırakıldığında, kuru zeminde ve 60 km hızdaki aracın içerisinde 68,6 dBA ses tespit edilmiştir. Aynı deney, yağışlı havada yapıldığında ise ses seviyesinin 70,86 dBA ölçülerine yükseldiği görülmüştür.

comunicación interna como herramienta de prevención y gestión del conflicto en las organizaciones hoteleras
Authors: Paradinas Márquez María del Carmen
Published: July 2020

Este artículo difunde el estado del arte en términos de manejo de conflictos en las organizaciones en general y de cómo la comunicación interna dentro de éstas resulta una herramienta clave para ello, para luego enfocar la investigación en la revisión de la literatura sobre el manejo de conflictos laborales en las organizaciones hoteleras y su relevancia para generar ventajas competitivas ya que en la actualidad resulta relevante el uso de las nuevas tecnologías por parte de los clientes para contrastar opiniones de otros usuarios a cerca del hotel en el que van a elegir alojarse. Si el conflicto aflora entre el personal laboral de la organización, el cliente lo percibirá, su opinión será negativa en las redes y afectará finalmente a la cuenta de resultados. Para ello, se analizaron libros, publicaciones de divulgación e investigación científica, tesis doctorales y sitios contrastados para asegurar su fiabilidad, introduciendo varias ecuaciones de búsqueda selectiva que permitieron seleccionar los documentos más relevantes para la investigación. Los resultados indican que, aunque existen numerosos estudios sobre la gestión de conflictos en las organizaciones y otros muchos estudios sobre comunicación interna, muy pocos se centran en el análisis de la comunicación interna como uno de los elementos que contribuyen a la prevención y gestión del conflicto y aún menos en el sector turístico, detectando así la necesidad de profundizar en este importante motor de la economía.

A Non-inverting soft switching buck-boost Converter is presented. One of the major hurdles that every converters face is switching losses. This loss is associated with the switches that are used to build the converters. To overcome this, magnetic coupling effect has been introduced to the proposed converter. This magnetic coupling effect helps the converter to obtain an adjustable soft switching range. Theoretically, it has been said that soft switching results in zero switching losses. That way, the losses due to switching can be neglected and that helps in improving the overall efficiency. In the paper, we have proposed a soft switching non inverting buck-boost converter and compared its performance characteristics with various other converters.

Fire occurring in forest has become a major crises, the hard part of this is passing information about fire occurred is delay which in turn allow to increase the spread of fire. There are two preeminent reasons on delay, first is place or region in which fire has occurred and the other is passing information about fire to outer world. Forest fire can be controlled using appropriate technique and officials can control the wild fire before spreading, if the information is passed fast. Human trespassing is one of the dominant acumen for wild fires. In order to know the type of the fire depending upon the region and also deportation of data about fire occurred, we framed a lay out, forest fire detector that uses wireless sensor networks. The detector is able to inform us whether it is a crown fire or ground fire depending upon the region using fire sensors and PIR via NodeMCU ESP8266. PIR is used to detect the presence of humans within the preserved regions of wild. The detectors that are connected to the NodeMCU pass the information to tan other NodeMCU using server client configuration. Depending on the type of fire, sprinklers are activated to control ground fire and drones carrying fire resistant dry chemicals are used to spread them from above for crown fire.

This project is an attempt to understand the suitability of the Single image super resolution models to video super resolution. Super Resolution refers to the process of enhancing the quality of low resolution images and video. Single image super resolution algorithms refer to those algorithms that can be applied on a single image to enhance its resolution. Whereas, video super resolution algorithms are those algorithms that are applied to a sequence of frames/images that constitute a video to enhance its resolution. In this paper we determine whether single image super resolution models can be applied to videos as well. When images are simply resized in Open CV, the traditional methods such as Interpolation are used which approximate the values of new pixels based on nearby pixel values which leave much to be desired in terms of visual quality, as the details (e.g. sharp edges) are often not preserved. We use deep learning techniques such as GANs (Generative Adversarial Networks) to train a model to output high resolution images from low resolution images. In this paper we analyse suitability of SRGAN and EDSR network architectures which are widely used and are popular for single image super resolution problem. We quantify the performance of these models, provide a method to evaluate and compare the models. We further draw a conclusion on the suitability and extent to which these models may be used for video super resolution. If found suitable this can have huge impact including but not limited to video compression, embedded models in end devices to enhance video output quality.

The research constitutes a distinctive technique of steganography of image. The procedure used for the study is Fractional Random Wavelet Transform (FRWT). The contrast between wavelet transform and the aforementioned FRWT is that it comprises of all the benefits and features of the wavelet transform but with additional highlights like randomness and partial fractional value put up into it. As a consequence of the fractional value and the randomness, the algorithm will give power and a rise in the surveillance layers for steganography. The stegano image will be acquired after administrating the algorithm which contains not only the coated image but also the concealed image. Despite the overlapping of two images, any diminution in the grade of the image is not perceived. Through this steganographic process, we endeavor for expansion in surveillance and magnitude as well. After running the algorithm, various variables like Mean Square Error (MSE) and Peak Signal to Noise ratio (PSNR) are deliberated. Through the intended algorithm, a rise in the power and imperceptibility is perceived and it can also support diverse modification such as scaling, translation and rotation with algorithms which previously prevailed. The irrefutable outcome demonstrated that the algorithm which is being suggested is indeed efficacious.

Information security is an important task on multimedia and communication world. During storing and sharing maintaining a strategic distance from the outsider access of information is the difficult one. There are many encryption algorithms that can provide data security. In this paper two of the encryption algorithms namely AES and RSA are implemented for color images. AES (Advanced Encryption Standard) is a symmetric key block cipher published in December 2001 by NSIT (National Institute of Standards and Technology). RSA (Rivest-Shamir-Adleman) is an asymmetric key block cipher. It uses two separate keys, one for encryption called the public key and other for decryption called the private key. Both the implementation and analysis are done in Matlab. The quality and security level of both the algorithms is analysed based on various criteria such as Histogram analysis, Correlation analysis, Entropy analysis, NPCR (Number of Pixel Change Rate), UACI (Unified Average Changing Intensity), PSNR (Peak Signal-to-Noise Ratio).

In agriculture the major problem is leaf disease identifying these disease in early stage increases the yield. To reduce the loss identifying the various disease is very important. In this work , an efficient technique for identifying unhealthy tomato leaves using a machine learning algorithm is proposed. Support Vector Machines (SVM) is the methodology of machine learning , and have been successfully applied to a number of applications to identify region of interest, classify the region. The proposed algorithm has three main staggers, namely preprocessing, feature extraction and classification. In preprocessing, the images are converted to RGB and the average filter is used to eliminate the noise in the input image. After the pre-processing stage, features such as texture, color and shape are extracted from each image. Then, the extracted features are presented to the classifier to classify an input tomato leaf as a healthy or unhealthy image. For classification, in this paper, a multi-kernel support vector machine (MKSVM) is used. The performance of the proposed method is analysed on the basis of different metrics, such as accuracy, sensitivity and specificity. The images used in the test are collected from the plant village. The proposed method implemented in MATLAB.

Over the last few decades the advent of machine learning has found applications in large number of domains. The ability to learn and identify patterns in data and make predictions on deviations from these patterns has found large scope in several fields. In computer networks, this problem can be applied to understanding the behavior of a network at any point of time and predicting when the behavior may change over time. This paper discusses an approach that uses a statistical machine learning algorithm for the time series behavior analysis of computer networks. The proposed algorithm makes use of unsupervised learning and statistical data analysis methods over the flows in the network. The novel aspect being explored is the analysis of the inter-dependencies between flows, in addition to monitoring anomalies of individual flows. The results presented, provide waveform representations of the correlation and clustering patterns of some sample flows based on packet sizes.

In Cloud Storage Server, data integrity plays an important role, given cloud clients might not be aware whether the data is safe or has been tampered with. This system introduces identity-based signature algorithms to protect data that belongs to the data owner and gets the status of cloud data by means of verification through signatures. Since it is practically not possible for the data owner to be available online all the time for checking cloud data integrity, Third party auditor is tasked with verifying the data integrity every time instead of data owner. The Third party auditors should not read the cipher text data while verifying and must authenticate itself to cloud server by performing Proof of Knowledge operation; then cloud server can reveal the sensitive data as block wise and the third party auditor can verify the signature without knowledge of cipher text data. Finally, an audit report is sent to the data owner. This work demonstrates data security and integrity in the cloud..
Neorealism in the work of Gianni Rodari. Reflections 100 years after the birth of the author
Authors: Carioli Stefania
Published: July 2020

Within the influence of Gramsci’s pedagogical model in the work of Gianni Rodari, this article examines the novel Piccoli vagabondi (Small vagabonds) (1952-1953), a unicum in the author’s production of Grammatica della fantasia (The Grammar of Fantasy), as it is characterized by neorealistic themes and by a communicative style that uses “proletarian” rhetoric, progressive vision and utopian elements. After mentioning the national issue of the non-existence of children’s literature (which Gramsci mentions in his essays on popular literature) and the neorealistic traits present in Rodari, the paper enters more directly into the merit of the neorealist novel, which presents itself as a document of the pedagogical effort (even contradictory) made by the Partito Comunista Italiano (Italian Communist Party) in the political climate of the “cold war” and as a testimony to the origin of the author’s search to reconcile realism with fantasy, dream and invention.

Published: July 2020

Este artigo tem por objetivo discutir memória e esquecimento sobre o trato com o conhecimento da luta marajoara no contexto das aulas de Educação Física no município de Soure-Marajó. Realizou-se pesquisa de campo com nove professores atuantes em escolas desse município. Utilizou-se questionário semiestruturado para entrevistas com professores da disciplina Educação Física e fez-se análise de conteúdo como método para analisar dados obtidos. Os resultados revelaram que a maioria dos docentes não trata o conhecimento da luta marajoara em suas aulas. Todavia, a constatação não seguiu a linha de culpabilização didática dos professores, mas colocou acento em ordem maior como questões relativas à memória social, ao esquecimento histórico e à alienação do trabalho. Conclui-se a importância de resgatar culturalmente a luta Marajoara como conhecimento local e global para florescer seu valor heurístico no trato pedagógico nas aulas de Educação Física.

Kemudian bayi tersebut akan tumbuh menjadi balita anemia yang jika tidak juga di tanggulangi dan akan kembali tumbuh menjadi remaja yang defiseinsi zat besi kembali.  Kondisi ini akan merugikan negara dan menghambat tujuan pembangunan nasional. Penelitian dilakukan pada remaja putri siswa di SMP Negeri LubukPakam sebanyak 116 orang. menggunakan desain crossectional. Data dikumpulkan melalui wawancara, food recall, pengukuran serta observasi, dan dianalisis menggunakan regresi logistic berganda. Tujuan penelitian untuk mengetahui faktor determinan yang berhubungan dengan kejadian anemia pada remaja putri siswa SMP Negeri  Lubuk Pakam. Hasil penelitian menyimpulkan bahwa faktor yang paling dominan memengaruhi kejadian anemia pada remaja puteri SMP adalah rata-rata asupan vitamin B12 dan skor pengetahuan gizi.  Asupan vitamin B12  serta pengetahuan gizi yang baik dapat masing-masing 2,04 kali dan 1,65 kali menurunkan kejadian anemia pada remaja puteri.
Homomorphisms of Sparse Signed Graphs

The notion of homomorphism of signed graphs, introduced quite recently, provides better interplay with the notion of minor and is thus of high importance in graph coloring. A newer, but equivalent, definition of homomorphisms of signed graphs, proposed jointly by the second and third authors of this paper and Thomas Zaslavsky, leads to a basic no-homomorphism lemma. According to this definition, a signed graph $(G, \sigma)$ admits a homomorphism to a signed graph $(H, \pi)$ if there is a mapping $\phi$ from the vertices and edges of $G$ to the vertices and edges of $H$ (respectively) which preserves adjacencies, incidences, and signs of closed walks (i.e., the product of the sign of their edges).  For $ij=00, 01, 10, 11$, let $g_{ij}(G,\sigma)$ be the length of a shortest nontrivial closed walk of $(G, \sigma)$ which is, positive and of even length for $ij=00$, positive and of odd length for $ij=01$, negative and of even length for $ij=10$, negative and of odd length for $ij=11$. For each $ij$, if there is no nontrivial closed walk of the corresponding type, we let $g_{ij}(G, \sigma)=\infty$. If $G$ is bipartite, then $g_{01}(G,\sigma)=g_{11}(G,\sigma)=\infty$. In this case, $g_{10}(G,\sigma)$ is certainly realized by a cycle of $G$, and it will be referred to as the \emph{unbalanced-girth} of $(G,\sigma)$.

It then follows that if $(G,\sigma)$ admits a homomorphism to $(H, \pi)$, then $g_{ij}(G, \sigma)\geq g_{ij}(H, \pi)$ for $ij \in \{00, 01,10,11\}$.

Studying the restriction of homomorphisms of signed graphs on sparse families, in this paper we first prove that for any given signed graph $(H, \pi)$, there exists a positive value of $\epsilon$ such that, if $G$ is a connected graph of maximum average degree less than $2+\epsilon$, and if $\sigma$ is a signature of $G$ such that $g_{ij}(G, \sigma)\geq g_{ij}(H, \pi)$ for all $ij \in \{00, 01,10,11\}$, then $(G, \sigma)$ admits a homomorphism to $(H, \pi)$.

For $(H, \pi)$ being the signed graph on $K_4$ with exactly one negative edge, we show that $\epsilon=\frac{4}{7}$ works and that this is the best possible value of $\epsilon$. For $(H, \pi)$ being the negative cycle of length $2g$, denoted $UC_{2g}$, we show that $\epsilon=\frac{1}{2g-1}$ works. 

As a bipartite analogue of the Jaeger-Zhang conjecture, Naserasr, Sopena and Rollovà conjectured in [Homomorphisms of signed graphs, {\em J. Graph Theory} 79 (2015)] that every signed bipartite planar graph $(G,\sigma)$ satisfying $g_{ij}(G,\sigma)\geq 4g-2$ admits a homomorphism to $UC_{2g}$. We show that $4g-2$ cannot be strengthened, and, supporting the conjecture, we prove it for planar signed bipartite graphs $(G,\sigma)$ satisfying the weaker condition $g_{ij}(G,\sigma)\geq 8g-2$.

In the course of our work, we also provide a duality theorem to decide whether a 2-edge-colored graph admits a homomorphism to a certain class of 2-edge-colored signed graphs or not.
Relationship between Teachers’ Demographic Characteristics and Levels of Utilization of Instructional Materials in Pre-Primary Schools in Kenya
Authors: Waigera Joseph K , Mweru Maureen , Ngige Lucy
Published: July 2020

Research indicates that children who obtain quality pre-primary education have a head start in life. It is also evident that early exposure and good use of instructional materials (IM) prepare children to be well adjusted later in life. Children are also well equipped with problem-solving skills that are important in Early Childhood Development and Education (ECDE). Instructional materials are core to effective teaching and learning in the formative years. The purpose of this research was to establish whether there was a significant relationship between teachers’ demographic characteristics and levels of utilization of instructional materials in pre-primary schools in Kenya. The study adopted the Cognitive Theory of Multimedia Learning Framework (CTML) and Ecological Systems Theory by Urie Bronfenbrenner. Besides, the study applied a cross-sectional survey research design. A random sample of 168 teachers comprising of 76.2% females and 23.8% males participated in the study. The Chi-Square test results indicated that gender (x2= 1.335; d.f. =1; p= 0.030), level of education (x2=8.165; d.f. =5; p=0.024) and professional training status (x2= 13.620; d.f. =5; p= 0.020) had a statistically significant linear relationship with the level of utilization of instructional materials. These results implied that female teachers were more likely to use instructional materials than their male counterparts and teachers who were more educated and highly trained were more likely to use instructional materials than their less trained counterparts. However, age, marital status, and duration of teaching experience had no statistically significant relationship with the utilization of instructional materials in pre-primary schools. It was concluded that professional training of pre-primary school teachers is critical for effective teaching and learning at the foundational level. It was recommended that teachers should promote the utilization of instructional materials in their classrooms for interactive and experiential learning of pupils.

Inverting the Evidence Hierarchy
Authors: Fulford Bill
Published: July 2020

When David Sackett launched his program as the founder Director of Oxford’s Centre for Evidence Based Medicine, he defined the field (in his seminal book, How to Practice and Teach EBM) as combining best research evidence with clinical experience and with individual patients’ values. Yet contemporary evidence-based medicine is largely taken up with the first of these, with best research evidence. Clinical experience is all-too-often subordinated to evidence-based guidelines: these are indeed only guidelines, not, as Gill Leng the Deputy Director of NICE repeatedly reminds us, tram lines; but clinical experience is in practice subordinated by them, nonetheless. While as to individual patients’ values, the third element of David Sackett’s original definition, individual case histories, as the vehicle for understanding what matters or is important to a given patient, come right at the bottom of the hierarchy of contemporary EBM.

The oribatid mite genus Sadocepheus Aoki, 1965 is recorded for the first time from the Philippines; one new species is described from the leaf litter of secondary forest in Mindanao Island. Sadocepheus donvictorianoensis Ermilov & Corpuz-Raros sp. nov. differs from the most similar species, S. elevatus Mahunka, 1987 by the larger body size, long medial and short lateral teeth of the lamellae and shorter adanal setae. Revised generic diagnosis and the data on distribution and ecology of Sadocepheus species are presented.
Rechazo sin evidencia: Prejuicio político entre jóvenes meridanos
Authors: Echeverría Victoria Martín , Garay Hernández Maricarmen
Published: July 2020

Una preocupación fundamental para la política mexicana es el aparente desinterés y apatía de los jóvenes hacia la participación política, sus instituciones y acontecimientos. Para abordar estos fenómenos, el trabajo aquí comentado partió de la socialización política y se concentró en las representaciones que los jóvenes tienen sobre el gobierno. Recurriendo a un diseño cualitativo consistente en grupos focales y entrevistas profundas, los hallazgos indican la reproducción de actitudes y valores de la cultura política mexicana en los jóvenes, una representación personalizada y apolítica del gobierno, y destacan el papel de la familia, uno de los pocos vínculos entre los jóvenes y el sistema político.
