Identificación molecular de clones Salix mediante RAPDs
Authors: Campos de Quiróz Hugo Alejandro
Published: July 2021

Debido a la propagación vegetativa del Salix, los mecanismos de identificación genética juegan un rol importante en el desarrollo de estas especies en Chile. Los sistemas tradicionales de identificación de especies y genotipos forestales, se basan principalmente en características morfológicas y fenológicas, cuya expresión presenta una gran dependencia del medio ambiente y del conocimiento de la especie. En consecuencia, es necesario desarrollar sistemas que permitan la rápida identificación de genotipos forestales. El desarrollo de marcadores moleculares RAPDs (Random Amplified Polymorphic DNA) permite una rápida identificación de clones y otros genotipos forestales mediante la amplificación selectiva de fragmentos del genoma de los individuos analizados. El presente estudio demuestra la utilidad de este enfoque, mediante la identificación molecular de un diverso grupo de procedencias Salix. A través de RAPDs y utilizando un solo partidor, fue posible identificar un conjunto de 24 procedencias analizadas. Los resultados obtenidos se discuten en términos de sus consecuencias genéticas y operativas, tanto para productores y viveristas como, para el desarrollo silvícola de especies Salix en Chile.
Recomendación-EDG (European Drying Group). Evaluación de la calidad del secado de la madera
Authors: Hernández C. Gonzalo
Published: July 2021

Esta entrega se refiere a una compilación y adaptación de las Recomendación-EDG (European Dying Group) para evaluar la calidad del proceso de secado de madera en cámaras. Esta forma de estandarización fue elaborada con la colaboración y cooperación de la industria maderera y de las Autoridades de Investigación e instituciones de investigación vinculadas al tema. Para todos los criterios de calidad de secado, se describen técnicas de medición a fin de facilitar el control y monitoreo empleando una normativa estándar. En esta recomendación se definen tres clases de calidad de secado: "Estándar" (S), "Secado de Calidad" (Q) y "Exclusivo" (E), para lo cual se han especificado los límites admisibles de la variación del contenido de humedad objetivo. Además, se entrega la forma de evaluar aquellas características adicionales que afectan la calidad del secado de la madera como lo son las grietas y rajaduras. Esta recomendación puede ser utilizada como punto de partida para fijar un estándar de control de calidad de la madera seca en cámara, por parte de los productores nacionales, ajustándolo a las características de las maderas nativas y exóticas presentes en el país.
Análisis económico de opciones productivas para plantaciones de Eucalyptus nitens en el Sur de Chile
Authors: Valencia Baier Juan Carlos , Cabrera Perramón Jorge
Published: July 2021

El establecimiento y manejo de plantaciones de Eucalyptus nitens para producir rollizos podados con alta proporción de madera libre de nudos para chapa o aserrío, conjuntamente con rollizos aserrables con nudo firme y madera pulpable, cada día cobra mayor interés en productores e inversionistas forestales, frente a la opción netamente pulpable; sin embargo, dado su relativo reciente desarrollo en Chile, son escasos los antecedentes sobre la rentabilidad de esta alternativa, situación que este trabajo busca mitigar mediante un análisis económico para la realidad productiva del sur del país. Con dicha finalidad se desarrolló un modelo de actualización de flujos de caja, con el cual se estimó y comparó la rentabilidad de invertir en plantar Eucalyptus nitens considerando: a) un "régimen clear" o "Manejo de alto valor", con edad de rotación de 20 años, incluyendo 3 podas y dos raleos comerciales; y b) la opción de producir solo madera rolliza pulpable, considerando para ello un flujo de caja de dos rotaciones de monte alto sucesivas, de 10 años cada una: forestación y reforestación. En ambos casos se estimó el Valor Neto Presente (VNP); el Ingreso Anual Equivalente (IAE) y la Tasa Interna de Retorno (TIR), para dos condiciones de productividad de sitio: alta (IMA 45 m³/ha-año; IS 33) y media (IMA 30 m³/ha-año; IS 26), representativas del rango de crecimiento observado en el sur de Chile. Además, se analizó la rentabilidad de la opción pulpable para dos rotaciones de monte alto de E. globulus, también bajo dos condiciones de sitio: 20 y 30 m³/ha-año, representativas de una productividad media a alta para la especie.
¿Pueden las plantaciones forestales actuar como catalizadoras de la sucesión secundaria? = Can tree plantations as catilizers of secondary forest succesion?
Authors: Montagnini Florencia
Published: July 2021

Estudios de diversidad vegetal bajo cobertura de especies forestales en varias regiones del mundo sugieren que las plantaciones presentan un buen potencial para acelerar los procesos de recuperación de la biodiversidad. La falta de agentes dispersores de semillas puede ser un impedimento importante para la regeneración de bosques en áreas de pastos abandonados. Las plantaciones forestales pueden facilitar la sucesión secundaria atrayendo agentes dispersores de semillas de bosques cercanos y creando un microclima que suprime la vegetación agresiva, favoreciendo la germinación y crecimiento de especies forestales. Las diferentes especies de las plantaciones arbóreas generan condiciones distintas de sombra y acumulación de hojarasca, determinantes de la abundancia de individuos reclutados y sobrevivientes a adultos. La selección de las especies promotoras de la restauración del bosque influirá en el porcentaje de individuos que permanecerán en cada etapa de la regeneración (colonización, establecimiento, crecimiento, sobrevivencia). Los resultados sugieren que las plantaciones pueden servir para catalizar o acelerar la sucesión natural, pero aún es incierto hasta qué punto la composición de especies se asemeja a los bosques maduros de la región. El presente estudio se realizó en plantaciones cuya edad de corte se estima en 15-25 años dependiendo de las especies. Estudios posteriores pueden verificar si la composición de especies favorecidas por las plantaciones es similar al de estados maduros de la sucesión natural en la región.
Incorporación de Boletus edulis y Boletus pinicola en plantaciones de Pinus radiata en Chile = Incorporation of Boletus edulis and Boletus pinicola in plantations of Pinus radiata in Chile
Authors: Chung Guin-po Patricio , Pinilla Suárez Juan Carlos , Casanova del Río Karoline , Soto Guevara Hernán
Published: July 2021

Pinus radiata, la especie forestal más plantada en Chile, presenta asociaciones micorrícicas con varias especies, dentro de las cuales se cuentan algunas de importancia económica en el rubro de los hongos comestibles de exportación. Estas corresponden a las especies Suillus luteus, Suillus granulatus y Lactarius deliciosus, cuyas fructificaciones se venden muy por debajo de los precios alcanzados por otras especies, como las pertenecientes a los géneros Tuber, Boletus, Cantharellus, Tricholoma o Morchella. Sin duda la incorporación al mercado nacional de nuevas especies de hongos micorrícicos comestibles y de alto valor económico, ayudaría a generar una mayor rentabilidad de las plantaciones de pino, otorgando una mayor atracción en la inversión en forestación y un mayor beneficio social. Por ello el Instituto Forestal realizó la introducción de dos especies micorrícicas de importancia, Boletus edulis y Boletus pinicola, para ser aplicadas en Pinus radiata, logrando incorporar estos hongos en plantas de vivero. Finalmente, se estableció ensayos en terreno, que abarcaron sitios de las Regiones del Maule y del Biobio, para evaluar a corto plazo la eficiencia de estos hongos en el crecimiento y sobrevivencia de las plantaciones y, más a largo plazo, la obtención de fructificaciones. Se presenta los resultados luego de 24 meses de establecido los ensayos, demostrando que aún persisten las asociaciones micorrícicas establecidas en las raíces. Los datos en terreno han destacando el aporte de estos hongos en el crecimiento de las plantas, presentándose un mayor crecimiento en las plantas con estas asociaciones.

El estudio del comportamiento de plantas de Eucalyptus sometidas a estrés salino es importante para asegurar de plantaciones con estas especies en áreas salinas. El objetivo de este trabajo es evaluar el efecto de concentraciones crecientes de NaCl en las características biométricas del tronco y el sistema radicular de plantas de eucaliptos. El experimento fue desarrollado en invernadero, empleando potes de 11,5 L con arena regada con una solución nutritiva. El diseño experimental fue factorial, completamente aleatorizado con cuatro especies (Eucalyptus camaldulensis, E. tereticornis, E. pellita y E. robusta), niveles crecientes de NaCl (1,41; 2,5; 4,5; 6,45 y 8,33 dS m-¹) y cinco repeticiones. Las concentraciones de NaCl, hasta 8,33 dS m-¹ de conductividad eléctrica, no comprometieron el desarrollo inicial de E. tereticornis. Sin embargo, el crecimiento de las plantas de E. camaldulensis, E. pellita y E. robusta, registró valores menores en respuesta a crecientes niveles de salinidad.

Authors: Vargas Rojas Victor
Published: July 2021

El trabajo presentado corresponde a una recopilación de experiencias con comunidades rurales y actores sociales, recogida durante 5 años en el marco de procesos de elaboración de estándares de manejo forestal sustentable, desarrollo e implementación de Guías de Mejores Prácticas Forestales y trabajo de gestación conjunto con cooperativas campesinas de especificaciones de Buenas Prácticas Forestales para la Agricultura Familiar Campesina. Se describe en el documento modelos exitosos de emprendimiento comunitario forestal, basados en antecedentes recopilados en talleres, visitas a terreno y reuniones de trabajo con propietarios entre las regiones del Maule y Los Lagos en Chile. Fruto del análisis de las experiencias se concluye que en la filosofía de los estándares de Certificación de Manejo Forestal Sustentable y Guías de Mejores Prácticas y en sus procesos de elaboración, se incorporan elementos básicos que pueden colaborar a que el Manejo Forestal Sostenible se constituya en un motor de desarrollo local para el mundo rural. No obstante, se hace necesario que los técnicos involucrados comprendan profundamente los procesos que se gestan al interior de estos grupos humanos y están abiertos a contrastar visiones de desarrollo en el amplio sentido del término.
Is the de-carbonization of air-transportation to and from the island of Crete, Greece feasible?Is the De-carbonization of Air-transportation to and from the Island of Crete, Greece Feasible?
Authors: Vourdoubas John
Published: July 2021

The clean energy transition is an important and urgent issue in European islands contributing in the global effort for climate change mitigation. Island of Crete, Greece is a popular tourist destination while the most of visitors arrive and depart with aircrafts. Aim of the current study is to investigate the possibility of de-carbonizing the air-transportation to and from Crete. Air-transportation has a share at 10.62% in the total carbon emissions in the island while other studies have estimated higher values. This is higher than the estimated share of carbon emissions in aviation at 2-3% of the overall carbon emissions worldwide. Various technological and non-technological approaches for de-carbonizing aviation are examined including improvements in aircraft’s standards, use of sustainable aviation fuels, offsetting carbon emissions and developing new policies discouraging the frequent use of air travelling. The feasibility and the impacts of these methods are mentioned indicating that de-carbonization is difficult in the short and medium term. Production of sustainable aviation fuels including bio-fuels and electro-fuels in the required quantities and in competitive prices is not foreseen soon. Developing new policies that increase the cost of air travelling and promote alternative sustainable modes in transportation will have undesired impacts in the island’s tourism industry. On the contrary de-carbonization in other socio-economic sectors in Crete comprising electricity generation, production of heat and cooling and transportation inside the island is easier than in air-transportation.

This study was carried out to determine the effects of replacement of wheat flour with wheat middling (WM) and supplemental phosphorus at a level of 1% on growth and nutrient utilization, whole body, fillet, viscera and liver proximate compositions in turbot, (Scophthalmus maximus Linnaeus, 1758). The control diet was based on a mixture of three fish meals and whole wheat flour. Fish with an average initial weight of 266.67±0.72 g were fed experimental diets for 9 weeks. Each treatment was tried in four replicates. At the end of the experiment, there were no significant effects of the treatment on growth rate, nutrient utilization parameters such as feed intake, feed conversion ratio, protein efficiency rate, nitrogen, lipid and energy gains and retentions, hepato-somatic index, viscero-somatic index, condition factor, whole body (except dry matter which was significantly lower in P added diet than the control) and organ nutrient compositions. The findings suggest that WM can totally replace wheat flour and there is a tendency of a positive contribution of dietary P supplementation on the response variables.
The Threat of Cyberattack in East Asia
Authors: Eaimrittikrai Choakchai
Published: July 2021

As businesses rely, in most countries, increasingly on the knowledge-based and value-added components of their offerings to secure suitable demand, the pressure on their internal infrastructure to maintain security has intensified. The range of potential adversaries continues to increase as commercial opportunities from cyber-attacks on their connectivity networks increases in both scope and scale. This paper considers the types of cyber-attacks that are being faced by organizations across East Asia and places these in the context of the political-economy of contemporary intellectual property rights. It is argued that multiplying risks threaten to overwhelm those organizations not prepared to take the issue seriously and to respond to those threats with appropriate rigor. Some implications for future practice are also derived from the analysis. Keywords: Cyber attack, threat, political economy

Authors: Nowak Prof. Dr. Hab A.Z. , Dahal Gangadhar
Published: July 2021

This research examines the presence of the long run relationship and triangular causality among per capita education expenditures, GDP per capita and per capita health expenditures in Nepal. In this study ARDL bounds testing approach is used to examine the presence of long-run relationship and Granger Causality test for calculating short run, long run and both short run and long run triangular causality between the variables for the time series data of Nepal from 1994/95 to 2014/15. This research paper started with the aim of finding the triangular causality between education, health and economic growth of Nepal. The results of the research analysis also supported the view that there is co-integration and interrelation between these three macroeconomic variables. The results from OLS also show that there is high contribution of education and health in economic growth. There is also strong triangular causality between education, health and economic growth of the nation in the long run which is tested through ADRL mode, Granger Causality test and VECM approach. It also focused on the long run causality between these three macroeconomic variables. This research undoubtedly shows that there is crucial role of education in health, economic growth (say GDP) and socioeconomic development of Nepal and many more least developed and developing countries in the world.

Foreign Direct Investment in Cambodia’s Telecommunications Industry
Authors: Ampornstira Fuangfa
Published: July 2021

In order to obtain a mobile telecommunications network rapidly and at low cost, the Cambodian government opened the sector to all comers wishing to make appropriate levels of investment. The subsequent turmoil of investment and aggressive marketing of products led to a situation of hypercompetitiveness, which is unsustainable and resulted in several companies subsequently divesting. Using the results of a programme of quantitative and qualitative research, this paper reports on these events and the implications of foreign direct investment in a lightly-regulated sector in which excessive competition may be solicited.

La caracterización de Judas Iscariote en el evangelio de Juan
Authors: Hernández Carracedo José Manuel
Published: July 2021

El evangelio de Juan realiza una relectura original de Judas Iscariote.En este trabajo se compara la caracterización joánica del hombre “que entregó” a Jesús con la de los Sinópticos. De esta forma, podemos descubrir y estudiar la especificidad de la puesta en escena de Judas en el cuarto evangelio. La originalidad del relato joánico radica tanto en la forma de presentar a Judas (enunciación) como en los rasgos teológicos que lo definen. Por último, se presentará la hipótesis de que el “Judas del cuarto evangelio” refleja a grupos judeocristianos distintos de los grupos joánicos o escindidos de ellos.
Propuesta agustiniana de filosofía política
Authors: Jáñez Barrio Tarsicio
Published: July 2021

La “civitas agustiniana” se mueve en un doble nivel: metahistórico e histórico. En el nivel metahistórico (místico) la “civitas” adquiere un sentido estricto o propio, equivalente a “reino”; en el histórico su sentido es derivado, secundario (impropio), equivalente a ciudad (res-publica) bien religiosa (Iglesia), bien política (Estado). Esta consideración previa, verdadero fundamento de la filosofía política agustiniana, nos lleva, seguidamente, a establecer, en primer lugar, la incompatibilidad absoluta entre las dos civitas meta-históricas (Civitas Dei et Civitas terrena), y en segundo lugar, a tres diferencias entre unas y otras “civitates”: la no identidad entre “Civitas Dei” e Iglesia, la no equivalencia entre “Civitas terrena” y Estado, y la gran diferencia (distinción) entre Iglesia y Estado. Desde aquí, creemos poder hablar de la conexidad real entre Iglesia y Estado, centrándola sobre el punto común que llamamos “quid medium naturale-humanum”, siempre que no se conciba un Estado radicalmente injusto e inhumano.
Los tratados sobre las vidas de santos en el barroco: el caso de santo Tomás de Villanueva (1488-1555)
Authors: Seguí Cantos José
Published: July 2021

Los tratados sobre las vidas de santos o en proceso de santidad se multiplicaron en la iglesia católica en el barroco usados como medio de propaganda del nuevo ideario tridentino frente al protestantismo, divulgando vidas de personalidades destacadas por su estudio de la Palabra de Dios, su práctica de sacramentos, oración y obras de caridad. Este fue el caso de santo Tomás de Villanueva que fue arzobispo de Valencia desde 1545 hasta 1555 y que fue beatificado en 1618 y canonizado años más tarde. El presente trabajo presenta las biografías del padre agustino Miguel Salon y de Francisco de Quevedo en torno a la vida del santo de 1620, con informaciones extraídas de las declaraciones de dicho proceso y con la finalidad de difundir a todo el pueblo cristiano las excelencias de la vida de santo Tomás de Villanueva como modelo y ejemplo.

Hermas, un escalador social, se dirige a los ricos de su comunidad
Authors: Álvarez Cineira David
Published: July 2021

La biografía de Hermas y la recurrente temática de la riqueza - pobreza en su obra nos permiten vislumbrar la composición social de su comunidad romana. Varios de sus miembros han logrado ascender en la escala social gracias a la adquisición de riquezas materiales por medio de sus florecientes negocios e intentan integrarse en la sociedad conforme a su nuevo status adquirido. Ello provocará que se distancien del grupo más numeroso de cristianos que continúan siendo pobres e indigentes, lo que provocará una fragmentación de la comunidad. Ante esta realidad comunitaria y exhortando a los ricos, Hermas aboga por la integración de los diferentes estratos sociales en una única comunidad mediante el patronazgo, donde el rico desempeñará un servicio importante gracias a la solidaridad que debe mostrar con los pobres, especialmente mediante la limosna y la hospitalidad… Por su parte, los pobres se especializarán en orar por los ricos, estableciendo así un intercambio mutuamente provechoso. Este pragmatismo de Hermas permitirá la integración de diversos estratos sociales en una única comunidad sin buscar la supresión de las diferencias económicas o sociales y otorgando una orientación social a las riquezas de los ricos.
Platón y san Agustín de Hipona según Charles Taylor
Authors: Martínez Pérez Francisco Javier
Published: July 2021

A partir de los distintos mapas morales de la antigüedad, Charles Taylor considera la evolución experimentada desde Platón a Agustín de Hipona como una evolución fundamental.[1] Según Taylor, el contraste entre las imágenes de Agustín y de Platón, pese a la continuidad en la teoría metafísica, reside en una importante diferencia filosófica. Mientras que para Platón el mundo de los objetos nos conduce al mundo de las Ideas y al orden racional, Agustín de Hipona abandona dicho enfoque y lo dirige al conocimiento de lo que cada uno de nosotros lleva dentro de sí y nos hace conscientes de ello en primera persona. Captamos lo inteligible no sólo porque el ojo del alma se dirija a los objetos sino por la intimidad de la autopresencia en Dios.
Female Leaders and the “Unawakened” Male: Gender, Power, and Propaganda in North Korean Cinema
Authors: Broinowski Anna
Published: July 2021

North Korean cinema is distinctive in its use of female protagonists to advance the propaganda objectives of the state. While men often play “failing” characters in need of conversion to the socialist ideology which every film promotes, women frequently embody the idealized hero: exhibiting the nationalistic self-reliance to which all citizens are encouraged to aspire. The function of “Mothers” and “Maidens” as revolutionary agents of change in key historical North Korean film texts is well documented; however, the subsequent evolution of North Korean heroines, and their ideologically problematic male counterparts, requires further examination. This article underpins an analysis of the disruptive femininities in play in three contemporary North Korean films with field research conducted in Pyongyang in 2012 to expand the Mother/Maiden binary: investigating how the power dynamics between the female “leader” and “unawakened” male are used to both promote the state’s sociopolitical aims and reinforce the supremacy of the Kim regime.

Published: July 2021

Background: Fertility is one of the main components of population growth. Knowing the fertility level of any society is important in assessing the economic and social conditions. Aim: To determine the attitude and practice of Zahedan women towards childbearing. Methods: This descriptive-analytical study was performed on 400 Iranian married women aged 15-38 years in Zahedan. Data were analyzed by SPSS 11.5 software. Descriptive statistics methods and analytical statistics methods were used. Results: The mean and standard deviation of the current number of the research units’ children was 2.54 ± 1.54 children. Regarding the tendency to increase the number of children, 65.8% of women and 66% of their spouses tended to have another child and the average number of their preferred children was 3.49 ± 1.44. Other results showed that the majority of the subjects (72.50%) had a moderate attitude towards childbearing. Conclusion: Considering that more than half of women wanted to have another child and the majority of them had a moderate attitude towards childbearing, this shows a positive attitude toward childbearing. On the other hand, it should be noted that government interventions alone can not be a solution to prevent declining population growth, and in this regard, public acceptance and cooperation can also play an important role.

FORMAÇÃO DE PROFESSORES DO ENSINO PRIMÁRIO NO CONTEXTO DA DIVERSIDADE CULTURAL – UM OLHAR AOS PROFESSORES DE LÍNGUA PORTUGUESA EM MOÇAMBIQUE
Authors: Nhambe Félix Alexandre
Published: July 2021

Com este artigo, pretendemos abordar a formação de professores primários de língua portuguesa no contexto da diversidade cultural, com a finalidade de reflectir sobre o currículo de formação de professores primários em Moçambique. A metodologia usada consistiu na pesquisa bibliográfica e documental na base do Plano Curricular do Curso de Formação de Professores do Ensino Primário e Educadores de Adultos entre outros documentos e as falas de 14 professores entrevistados. Parece-nos que há a necessidade de incorporação da Pedagogia da Diversidade e Desenvolvimento Curricular na formação de professores, pois elas não estão previstas e cursos solidificados, seguros e estáveis de professores. Estas preparariam aos futuros professores em reflexão crítica do currículo do Ensino Básico e em desenvolvimento da consciência nos alunos sobre a diversidade linguística, cultural e da biodiversidade, no sentido de orientá-los para uma actividade que lhes é significativa, possibilitando-os na construção da sua identidade, da condição humana e da cidadania no quadro da teoria pós-estruturalista e pós-crítica. Ter um professor bilingue equilibrado seria um cenário adequado tendo em conta o local de trabalho e uma política linguística que favorece todas as línguas do espaço moçambicano no ensino. Sem estas ferramentas pode haver dificuldades para os professores porque estes vão trabalhar num contexto de diversidade cultural e linguística, devendo leccionar, por vezes, as línguas Bantu e o Português, não bastando o conhecimento das Estruturas das Línguas Bantu, da Didáctica da Língua Primeira/Materna, Didáctica da Língua Segunda, Língua Portuguesa, Literatura Oral, da situação linguística e cultural do país.

Esta pesquisa visa compreender, a partir da ótica dos professores e gestores, os efeitos do IDEB na Escola Municipal Raquel Ramão da Silva em Cáceres – MT. Assim, o problema deste estudo constituiu-se em saber: quais as implicações do IDEB na escola estudada e que ações foram desenvolvidas pela escola nas diversas situações apontadas nos resultados e como essas ações se materializaram no espaço escolar? Para tanto, efetuamos um estudo referente a avaliação externa em larga escala na educação básica no Brasil, bem como o papel do Estado e das instituições escolares. Os resultados demonstraram que os sujeitos compreendem que a política de avaliação em larga escala é necessária, apesar de evidenciarem que os dados divulgados são insuficientes para compreensão da realidade, e que o município oferece pouco ou nenhum suporte técnico e financeiro na superação das dificuldades apresentadas. Também ficou evidenciado que esses resultados não são utilizados como melhoria das práticas pedagógicas, principalmente, as que se realizam no contexto da sala de aula nas relações professor aluno.
Impact of WhatsApp on the Vocabulary Acquisition of Secondary School Students in Ogbomoso, Oyo State, Nigeria
Authors: Salman Abdulmalik Abiola , Imam Muhyideen Olasunkanmi
Published: July 2021

The advent of technology has brought a change in the dynamics of second language teaching and learning. WhatsApp has been a common tool used among students for communicating and chatting with friends, peers, and relatives. Its commonality may be because of its easy installation as mobile application on mobile devices. Educators are beginning to explore its potentials toward seeing how it can help students in their learning. Since it is apparently a novel tool in the education sector, its usefulness in acquiring vocabulary by secondary school students is yet to be ascertained. Therefore, this study examined the impact of WhatsApp on vocabulary acquisition of secondary school students in Ogbomoso, Oyo State, Nigeria. This study was premised on the constructivist learning theory since WhatsApp provides students the opportunity to construct their vocabulary knowledge. The sample for the study comprised 250 students from five secondary schools randomly selected in Ogbomoso, Oyo State. Data for the study were generated from the participants using self-made questionnaire. The questionnaire is structured into 5 points from Strongly Agree to Strongly Disagree. Mean and standard deviation were employed to analyse the data. Findings showed that more than half of the students believe WhatsApp is expedient in learning and acquiring vocabulary. It further revealed that the majority of the students perceive WhatsApp as an effective social network that enhances their vocabulary acquisition as it is easy to acquire new words and understand their meanings through WhatsApp. The study concluded that language teachers should devise means of adopting social media such as WhatsApp to teach their students since students are favourably disposed to learning through WhatsApp.

Parasitic disease is considered among the limiting factors in freshwater fish production. Fish is a cheaper source of animal protein available to the people thus, the need to control parasites that affect their productivity. Three hundred and twenty (320) Hyperopisus bebe occidentalis obtained from River Galma at Dakace, Zaria between August, 2016 and February, 2017 were examined for gastro-intestinal helminths using the formal-ether concentration techniques. Results obtained showed that 124 (38.8%) fish examined were infected by the acanthocephalan Rhadinorhynchus horridus and no other helminthes were recovered. The worms recovered were mainly from the small and large intestines, with the mid-intestine accounting for the greatest number of parasites with 90.74%. There was a general increase in infestation with increase in size of fish and there was no significant difference between the infections of male and female fish.
Geology and Mining: An Introduction and Overview
Authors: AO Dan Wood
Published: July 2021

Postdevelopment studies show that, once in operation, about 70% of mines perform below the prediction of their feasibility studies, with underperformance usually caused by deficiencies in the collection of primarily geology related data prior to designing the mine and planning its operation. A major reason for these deficiencies is probably a generally narrow understanding by many geologists of metallurgy as well as geotechnical and mining engineering. Additionally, geologists often do not appreciate the types and quantities of data required by metallurgists, geotechnical engineers, and mining engineers for mine design, planning, and operations. Critically, there is commonly inadequate communication between all four professional groups. For obvious and logical reasons, the principal focus of geologists has generally been considered the discovery of a mineral deposit and subsequent resource definition and estimation of its grade and tonnage, leading to the creation of detailed geologic and grade models of the deposit. While grade and tonnage are cornerstones to mine development, equally important to mine design is the geotechnical model, which is constructed progressively over three stages of mining study using information obtained from four separate geology-related models. Enhanced understanding of mining and metallurgy by geologists plus appreciation of the metallurgical and mining uncertainties inherent in geologic data by metallurgists and geotechnical and mining engineers can contribute to significantly improved mining outcomes.

Objetivo: Este artigo visa atribuir valor à influência de alguns aspectos característicos do futebol presentes no processo de precificação dos ingressos dos jogos, tendo como foco o torcedor.Método: Segundo o enfoque quantitativo, é utilizado um modelo regressivo à luz da metodologia hedônica aplicada sobre uma base de dados primária, coletada no Estado de São Paulo, Brasil, com intuito de obter os preços implícitos de cada fator no preço realizado dos ingressos.Originalidade/Relevância: Apresenta-se um estudo que, através de uma proposta de modelagem inédita ao contexto do marketing esportivo aplicada a uma base de dados primários, busca o entendimento do quanto, em termos monetários, aspectos estruturais ou individuais afetam o preço realizado dos ingressos de jogos esportivos.Resultados: Algumas características relativas ao jogo se mostraram relevantes e tiveram seus preços implícitos estimados em relação a um chamado preço-base, como o clube mandante (com estratos de acréscimo no preço entre 31,31 a 163,10%), forma de aquisição (com a bilheteria e o cambismo incrementando o preço em 14,74% e 166,28% em relação aos programas de relacionamento, respectivamente) e qualidade do estádio (aumento de 61,75% no preço para os estádios mais bem classificados nesse quesito).Contribuições teóricas/metodológicas: A principal contribuição teórica é a aplicação da teoria hedônica ao composto de preço à realidade dos torcedores de futebol e sua sensibilidade a esse constructo. Valeu-se para tanto como proposta metodológica da modelagem hedônica, que permitiu determinar alguns dos principais atributos de segmentação destes consumidores e o impacto que tiveram na precificação dos ingressos por parte dos clubes e organizadores.Contribuições para a gestão: Diante da inciativa de profissionalizar a gestão esportiva no Brasil, com a ocorrência recente de grandes investimentos tanto públicos e privados (como os estádios da Copa do Mundo), espera-se que tal conhecimento possa ser relevante no sentido de aproximar as preferências de torcedores como consumidores da ação dos clubes e entidades gestoras do esporte (confederações, consórcios e patrocinadores).

Waches Gewissen - Aufruf zum Widerstand
Authors: Schröder Johannes
Published: July 2021

Bewegende Dokumente eines protestantischen Wehrmachtpfarrers im Widerstand gegen Hitler.

Der Wehrmachtpfarrer Johannes Schröder hatte sich schon als junger Pastor für die Ziele der Bekennenden Kirche eingesetzt. An der Front wollte er diese auf seine eigene Weise verfolgen. Nachdem er 1943 bei Stalingrad in sowjetische Kriegsgefangenschaft geraten war, schloss er sich dem Nationalkomitee »Freies Deutschland« an und bekam die Möglichkeit, sich über den Rundfunk in über 80 Ansprachen an Hörer und Hörerinnen in Deutschland zu wenden. Die in Schröders Nachlass erhaltenen und hier zum ersten Mal vollständig edierten und kommentierten Predigten und Ansprachen zeugen von seinem wachen Gewissen und seinem Willen, dem Ungeist der Nationalsozialisten Widerstand zu leisten, ebenso wie von der Hoffnung auf ein neues und freies Deutschland nach dem Krieg.

Die Dokumentation wird erschlossen durch Essays zu seiner Biographie, zum historischen Hintergrund, zu seiner theologischen Haltung sowie zur musikalischen Begleitung der Predigten.
Hope and Satisfaction with Life: Testing the Mediating Roles of Self-Esteem in three Asian Cultures
Authors: Bernardo Allan B. I. , Khan Aqeel , Salanga María Guadalupe C.
Published: July 2021

The relationship between well-being and the personal strength of hope has been elaborated by the identification of internal (self) and external (family, peers, spiritual) locus-of-hope dimensions. Du, Bernardo, and Yeung (2015) showed that self-esteem (personal and relational) mediates the relationship between locus-of-hope and life satisfaction. Locus-of-hope’s goal-related thoughts involve self-evaluation that may either enhance or diminish self-worth, which then influences life satisfaction. We tested the mediated model in three cultural groups: Malaysians, Macau Chinese, and Filipinos. Participants completed scales measuring locus-of-hope, personal and relational self-esteem, and life satisfaction. Path analysis showed significant indirect effects in all cultures: (a) internal locus-of-hope on life satisfaction, mediated by personal self-esteem, and (b) external-family locus-of-hope on life satisfaction, mediated by relational self-esteem. Other significant indirect effects were found in specific cultural groups. Cross-cultural similarities and differences are discussed with reference to how distinct cultures give different meanings to forms of agency associated with the personal strength of hope, creating distinct pathways towards life satisfaction.
Alternativas corporativas a la crisis del parlamentarismo español (1898-1936)
Authors: González Cuevas Pedro Carlos
Published: July 2021

Desde finales del siglo XIX, pero, sobre todo, desde el final de la Gran Guerra, el régimen parlamentario liberal sufrió, en la mayoría de las sociedades europeas, una profunda crisis de legitimidad. En esos momentos, las sociedades europeas experimentaron un proceso de «corporativización» que puso en cuestión la concepción liberal de la sociedad. Como alternativa al sistema todavía vigente, se propuso la alternativa corporativa, basada en la concepción orgánica de la sociedad y en la representación de intereses. Sin embargo, no puede hablarse de un único modelo de régimen corporativo; existen diversas variantes: la tradicionalista, la social católica, la liberal-organicista y la fascista. En ese sentido, puede distinguirse entre «corporativismo social» y «corporativismo de Estado». Como en el resto de Europa, España experimentó este proceso político-social de manera traumática.

This issue of the Journal for Research in Mathematics Education is the first in which my name appears as editor, and this occasion leads me to reflect on what contributes to the success of a journal such as JRME. That reflection starts with thinking about what previous editors have done to make it a success, and there is no better place to start than with the previous editor, Steve Williams, and his team.
Preservice Elementary School Teachers' Conceptions of Multidigit Whole Numbers
Authors: Thanheiser Eva
Published: July 2021

Although preservice elementary school teachers (PSTs) lack the understanding of multidigit whole numbers necessary to teach in ways that empower students mathematically, little is known about their conceptions of multidigit whole numbers. The extensive research on children's understanding of multidigit whole numbers is used to explicate PSTs' conceptions of these numbers. A grounded theoretical approach leads to the development of a framework for PSTs' conceptions of multidigit whole numbers, and that framework facilitates description of their conceptions and their difficulties in the context of the standard algorithms. The framework also enables discussion of the PSTs' performance in other contexts.
Construction Visualization Modeling
Authors: Ligetti Christopher B. , Finke Daniel A. , Bean Jim
Published: July 2021

This paper discusses the development of a software tool that utilizes light-weight versions of 3D digital product models and detailed module construction and erection schedules to visually validate and modify the erection sequence. The tool enables planners to quickly and easily modify the schedule to improve the sequence during the planning phase, where planners with limited knowledge of the predecessor/successor relationships can visually determine erection sequence conflicts. In addition, the Erection Visualization Tool (EVT) provides a means for communicating module status and aids decision making throughout the erection process to avoid excess construction costs and ensure on time delivery of ships.
SPS Overlay: 23500 sq.ft RoRo Main Deck Plating Renewal, 30 days off-hire

Published: July 2021

The plating of the main deck of the ropax ferry PRINCESS OF ACADIA (1971) was renewed during the month of March 2010 using Sandwich Plate System (SPS) Overlay. In comparison to conventional repair methods the processes used reduced costs and the out of service time making the deck renewal on the elderly ship viable. The SPS Overlay was installed afloat at the ferry terminal whereas a conventional renewal would have required drydocking the ship. This paper describes the project execution details, the steps involved in applying the SPS Overlay and summarizes the post project impact on the ship’s operational characteristics including passenger impact and future maintainability. SPS Overlay is the conversion of a stiffened plate into a composite plate structure with stiffeners. In the project presented, the existing deck plating is utilized as the bottom faceplate in the newly formed composite deck plating comprising a new steel top plate separated from and fully bonded to the bottom faceplate by a polyurethane elastomer core material. The conversion to an SPS composite deck structure is performed quickly, does not disrupt existing structure, services or insulation and allows other work to be performed in parallel.
