Education in consultation: A comparative survey-based assessment of perceived educational effectiveness within a university and community-based internal medicine residency
Authors: Rope Robert , Merrell Sylvia Bereknyei , Stedman Margaret , Young Brian
Published: September 2017

This article was migrated. The article was marked as recommended. Background: Education in consultation is a potentially valuable, but understudied, element of medical education. Inpatient consultation is an opportunity for significant subspecialist contact for resident trainees and an avenue for improving their knowledge and patient care across content areas. We evaluated the perceived educational effectiveness of education in consultation among internal medicine residents, within a university and a community-based program, as well as the role of barriers in medical training that may limit education. Methods: We used a web-based survey expanded from a previously published survey consisting of 12 questions, including one free-response, on education in consultation. Data were analyzed descriptively and qualitatively. We surveyed residents from two internal medicine programs in 2016. One within a large university-based hospital and the second within a smaller community-based safety-net hospital. Results: 91/198 (46%) of residents responded. Overall results from both programs were similar despite their structural differences. Residents viewed education in consultation as a priority and the majority felt it was at least moderately effective but underutilized. Importantly, educational interactions are largely dependent on outreach from residents. While in-person teaching interactions were the most effective, key barriers to these interactions include a lack of time, difficulty locating residents, and the perception of residents as being too busy. Conclusions: Inpatient consultation offers a unique opportunity for specialist-led education for internal medicine residents. It is potentially effective but constrained extensively in modern training environments. Interventions aimed at emphasizing education in consultation within fellowships and residencies, increasing in-person resident-specialist interactions, and addressing structural barriers, may improve resident knowledge across specialties and strengthen patient care.

Authors: Nasrullah Mochamad , Widodo Wiku Lulus
Published: September 2017

ABSTRAK PERHITUNGAN BIAYA OPERASI DAN PERAWATAN PLTN SKALA BESAR DAN KECIL. Biaya pembangkit PLTN terdiri dari tiga komponen, yaitu biaya investasi, bahan bakar dan operasi perawatan (O & M). Besarnya biaya O&M pada PLTN besar dan kecil tidaklah sama. Studi ini bertujuan untuk menghitung biaya O&M PLTN skala besar dan kecil dengan mempertimbangkan parameter teknis dan ekonomis yang diambil dari berbagai data sekunder dan sumber lainnya. Studi dilakukan menggunakan data dari PLTN jenis PWR dengan daya 1343 MWe untuk PLTN ukuran besar dan daya 90 MWe untuk PLTN ukuran kecil. Asumsi digunakan tingkat eskalasi sebesar 5%, faktor kapasitas 90%. Metodologi yang digunakan adalah menghitung dengan spreadsheet yang meliputi skala masing-masing komponen O&M. Hasil perhitungan menunjukkan biaya O & M jika dihitung dengan satuan juta US$/tahun, maka biaya O&M PLTN 1343 MWe sebesar 99,21 juta US$/tahun lebih mahal dari PLTN 90 MWe sebesar 45,13 juta US $/tahun. Namun jika biaya O & M PLTN 1343 MWe dihitung dengan satuan mills $/kWh, maka hasilnya  sebesar 9,37 lebih murah dibandingkan dengan PLTN 90 MWe yaitu sebesar 63,70 mills $/kWh. Hal ini berarti semakin kecil ukuran kapasitas dayanya maka biaya operasi dan perawatannya semakin mahal. Penyebab perbedaan biaya operasi dan perawatan antara PLTN skala besar dan kecil, adalah kapasitas daya, faktor kapasitas, jumlah personal yang bekerja pada biaya administrasi umum pegawai dan manajemen, operasi pembangkit tahunan, biaya tenaga kerja offsite. Kata kunci : Biaya operasi dan perawatan, PLTN, LEGECOST ABSTRACT CALCULATION OF OPERATION AND MAINTENANCE COST FOR LARGE AND SMALL SCALE NPP. The generation cost of nuclear power plant consists of three components:  investment costs, fuel cost operation and maintenance (O&M) cost. O&M costs in the large scale of NPP is different from small scale NPP. The objective of this study are to calculate the O&M cost of large NPP and small NPP by considering technical and economic parameters from secondary data and  other references. This study uses 1343 MWe PWR data for large NPP and 90 MWe PWR for small NPP. The assumptions are 5% escalation level and 90% capacity factor. The methodology for calculation using spreadsheet with scaling methods for each O&M components. The results shows that the O &M cost if calculated in units of million US$/year, the O&M cost of NPP 1343 MWe is US$million 99.21/ year which is more expensive than the O&M cost of NPP 90 Mwe which is only US$million 45.13/ year.  But if the cost of O&M 1343 MWe nuclear power plant unit is calculated in units of mills $/kWh, the result shows that the O&M cost is 9.37 mills $/kWh which is less than the 90 MWe NPP which reaches $ 63.70 mills/kWh. The conclusion is  lower NPP capacity  has higher O&M cost. Different O&M cost is caused by power capacity, capacity factor, the amount of worker on site staff, the annual net generation and the offsite technical support.

Authors: Iswanto Eko Rudi , Yee Eric
Published: September 2017

COMPARISON OF EQUIVALENT LINEAR AND NON LINEAR METHODS ON GROUND RESPONSE ANALYSIS: CASE STUDY AT WEST BANGKA SITE. Within the framework of identifying NPP sites, site surveys are performed in West Bangka (WB), Bangka-Belitung Island Province. Ground response analysis of a potential site has been carried out using peak strain profiles and peak ground acceleration. The objective of this research is to compare Equivalent Linear (EQL) and Non Linear (NL) methods of ground response analysis on the selected NPP site (West Bangka) using DeepSoil software. Equivalent linear method is widely used because requires soil data in simple way and short time of computational process. On the other hand, non linear method is capable of representing the actual soil behaviour by considering non linear soil parameter.  The results showed that EQL method has similar trends to NL method. At surface layer, the acceleration values for EQL and NL methods are resulted as 0.425g and 0.375g respectively. NL method is more reliable in capturing higher frequencies of spectral acceleration compared to EQL method.

Rantai pasok industri baja sangat diperlukan untuk mengetahui potensi industri baja dari hulu sampai hilir yang diharapkan dapat mendukung pembangunan PLTN tersebut secara berkelanjutan. Jenis baja yang dibutuhkan dalam konstruksi  PLTN adalah  baja struktur, rebar, pelat baja dan lain-lain. Tujuan penelitian ini adalah mengidentifikasi rantai pasok industri baja dari industri hulu sampai hilir sehingga dapat melihat kemampuan industri nasional dalam memasok kebutuhan baja untuk pembangunan PLTN. Metodologi yang digunakan adalah kajian literatur dan survei industri dengan cara purposive sampling test yakni mengirimkan kuesioner dan melakukan kunjungan teknis ke industri yang dianggap berpotensi  memasok komponen baja untuk konstruksi PLTN. Dari hasil analisis terhadap kuesioner dan survei telah diperoleh industri baja Indonesia yang mampu memasok baja untuk bahan konstruksi PLTN non nuklir, yaitu PT. Krakatau Steel, PT. Gunung Steel Group (PT. Gunung Garuda dan PT. Gunung Raja Paksi), PT. Cilegon Fabricators dan PT. Ometraco Arya Samanta. Sedangkan bahan baja untuk komponen utama dengan grade nuklir, seperti bahan baja untuk bejana reaktor dan bejana tekan, industri baja Indonesia belum mampu memasoknya, karena belum memenuhi persyaratan spesifikasi, kode dan standar grade nuklir Oleh karena itu, industri baja Indonesia harus meningkatkan kemampuan, baik dalam pengolahan bahan baku dan kemampuan fabrikasi agar dapat memenuhi persyaratan tersebut.
TEACHING NEW VOCABULARY TO IRANIAN YOUNG FL LEARNERS: USING TOTAL PHYSICAL RESPONSE AND KEYWORD METHODS
Authors: Toghyani Khorasgani Amir , Khanehgir Mansour
Published: September 2017

Early language learning for children is increasingly common, and the majority of parents and the public do not see it as superfluous or overburdening children. Moreover, teaching a foreign language to very young children has been an increasingly dominant trend in most globalized societies. While there is abundant literature that supports teaching a foreign language at an early age through language immersion programs, little is known about the efficiency of strategies used to explicitly teach new vocabulary words in a foreign language to young learners. This empirical investigation aimed to assess and compare the efficiency of two mnemonics that have been traditionally used to explicitly teach new foreign language words: the Keyword Method (KWM) and the Total Physical Response (TPR). Results indicate that the KWM is more effective than TPR in teaching new vocabulary words in a foreign language to early elementary school children.
Problemática vecinal y batalla ciudadana en la transición democrática en Jaén: 1975-1984
Authors: Gómez Fernández Ana Belén
Published: September 2017

El surgimiento de las asociaciones de vecinos tiene lugar en un contexto caracterizado por los graves problemas urbanísticos que existían en los barrios periféricos a finales de la década de los sesenta y durante los setenta. Así, su nacimiento se debe enmarcar en los últimos años del franquismo y los inicios de la transición democrática. Los vecinos van a demandar no sólo aquellas necesidades materiales básicas, sino también una mayor participación ciudadana en las instituciones locales, denunciando a los últimos Ayuntamientos franquistas y depositando su esperanza en los nuevos consistorios. Jaén no va a quedar al margen de esta situación, a pesar de que tradicionalmente el movimiento vecinal ha venido destacando en las grandes ciudades españolas. Se distingue su tardío inicio, aunque su génesis y desarrollo confirmarán como los mecanismos de lucha y protesta sentaron las bases de una importante participación popular.
Etnografía de los etnólogos: Experiencias del (Re) Encuentro Internacional de Arqueología y Etnohistoria en Cochabamba
Authors: Müller Seborga Juliane Angie
Published: September 2017

A partir del trabajo de campo, de la exposición de trabajos arqueológicos, históricos y antropológicos y los recesos durante seis días, se presenta ante nuestros ojos un ritual donde se observan situaciones sociales de segregación y etnocentrismo por parte de la élite y los "iniciados", al grupo de novatos que presenta su ofrenda para acceder a la información; donde los conocimientos son un bien material e inmaterial en una comunidad pequeña, de rituales imperecederos y que siente gran atracción hacia el “otro exótico”.

El presente trabajo se constituye en una etnografía crítica que toma como objeto de estudio la comunidad esporádica que se forma en el Encuentro Internacional de Arqueología y Etnohistoria en Cochabamba, Bolivia en 2015. Donde los investigadores se convierten en los “sujetos de estudio”, con la intencionalidad de volcar los papeles que por tanto tiempo han permanecido en el juego de alteridad de investigador/sujeto/objeto en Bolivia.

El reality show, entre el entretenimiento y el espectáculo: Discursos mediáticos contemporáneos
Authors: Brito Alvarado Leonardo Xavier , Capito Álvarez Paola
Published: September 2017

: El presente ensayo aborda la narrativa del entretenimiento, el espectáculo y la repetición como discursos mediáticos que se han afianzado, de manera especial, en los reality shows que han captado especialmente, gran parte, de la programación de la televisión. Estos discursos no solo representan discursos televisivos, sino que pueden constituirse en miradas profundas y transversales de las sociedades. A partir de lecturas antropológicas, comunicacionales y sociológicas, el presente ensayo reflexiona estas categorías como discursos imperantes en la televisión, que han desembocado en narrativas imperantes en la pantalla. La seducción de estos programas ha desemboca en pensar dentro de una lógica “light” de superficialidad narrativa y de la misma vida.
El pasado glorioso en los museos de la Habana: Una propuesta metodológica para su análisis
Authors: Puebla María Florencia , García Perdigón Jorge Rolando
Published: September 2017

Actualmente existe un creciente interés por estudiar las curadurías museológicas, porque simbolizan un aspecto vital en la conformación de identidades ciudadanas del presente. Siguiendo esta idea, se investigaron cuatro espacios museales de la ciudad de La Habana (Cuba), dos que exponen acontecimientos y organizaciones sociales representativos de la Revolución (como el Museo de La Revolución, y el Museo 28 de Septiembre de los Comité de Defensa de la Revolución), y dos que presentan a personajes claves del proceso revolucionario (Museo Casa Natal de José Martí, y Centro Cultural Casa del Che). Se propuso una metodología novedosa que combinó el análisis del discurso, la hermenéutica y la fenomenología. Su aplicación evidenció una explícita tendencia a reforzar una identidad revolucionaria en el presente, mediante la resignificación de un pasado glorioso con el fin de que sean los propios ciudadanos, los que conserven y defiendan al socialismo en el futuro de cambios que se aproxima.
Análisis de factores culturales y procesos de especiación en poblaciones de ectoparásitos de poblaciones humanas. El caso particular de los piojos asociados a los humanos
Authors: Retana-Salazar Axel Pedro
Published: September 2017

En este trabajo se exponen la revisión de tema acerca de los factores que pueden afectar la especiación y diferenciación de ectoparásitos en poblaciones humanas. Se presenta una revisión de diferentes grupos de parásitos en humanos y como los factores antropogénicos pueden afectar a estas poblaciones. Se detalla el caso de algunos ectoparásitos que sin específicos presentan diferencias en sus poblaciones aisladas en diferentes hospederos. Se utiliza el caso de los piojos humanos como un caso de estudio debido a que hay controversia acerca de las especies que parasitan al ser humano. Se analiza como los segregados morfológicos hallados en diferentes poblaciones de humanos que se mantienen en relativo aislamiento mantienen trazas morfológicas fácilmente diferenciables incluso a nivel de estructuras asociadas a la genitalia. Las evidencias obtenidas de piojos de momias de la cultura Chinchorro (Chile) indican que esta separación es milenaria. En algunos casos los datos moleculares evidencian la posibilidad de divergencias de linajes que conducen a procesos de especiación simpátrica. Este puede estar sucediendo en las formas de piojos que están parasitando a las poblaciones humanas, pero la evidencia molecular es controversial y los biólogos moleculares se reúsan a utilizar otras evidencias para la determinación de las especies. Este análisis indica que el comportamiento de las poblaciones humanas puede ser una presión de selección más en este proceso, aunque no se refleje con claridad en los procesos genéticos.
Los gitanos y el flamenco en el cine español. Por la interculturalidad en educación secundaria
Authors: López-Peláez MILAGROS , López-Peláez María Paz
Published: September 2017

En las siguientes páginas se aboga por la utilización del cine como herramienta educativa en distintas áreas de educación secundaria. En concreto, se propone el visionado y análisis de películas y fragmentos de películas en los que miembros de la etnia gitana tienen un papel destacado. De acuerdo con el Curriculum Mil de la UNESCO, el visionado y el análisis de  películas puede servir para hacer reflexionar al alumnado sobre conceptos complejos como son la raza o la identidad y para abordar cuestiones referentes a la supuesta objetividad del conocimiento. La reflexión sobre la imagen frecuentemente estereotipada que se ofrece de esta etnia en el cine es el punto de partida de una actividad que, basada en una pedagogía de raíz socrática, pretende facilitar la adquisición de conocimiento reflexivo-complejo, potenciar el espíritu crítico y desarrollar capacidades y competencias que serán indispensables al alumnado como ciudadanos de una democracia.

Materialism new and old
Authors: Wolfe Charles T.
Published: September 2017

New materialism is not a clear-cut set of theses, or a firmly unified school of thought. It crosses discourses and theoretical commitments, but, as its name indicates, seems consistently to oppose ‘new’ materialism to an older form, or perhaps several older forms of this doctrine. The latter are typically associated with ‘mechanistic’ standpoints, with ‘reductionism’, with the denial of life, agency, embodiment, meaning, value … What happens when a historian of materialism confronts such claims? In what follows, I reflect on the historical problems which affect such theoretical positionings. It is not that there is no need to distinguish passive from active forms of materialism, or single out a focus on organic life. But that a distinction between ‘new and old’ might not be the way to capture such crucial theoretical and historical features.
A new experimental approach to the study of beauty
Authors: Vico-Prieto A. Félix , Rosas Juan M. , Callejas-Aguilera José E. , Cagigas Angel
Published: September 2017

Theories of beauty perception have tilting between the importance of the golden section, and the importance of cultural and learning factors on perception of beauty. The contradiction between those approaches may be solved by taking in account the real golden proportion rather than the ideal golden proportion. A new framework to conduct new and more comprehensive experimental approaches to the study of beauty is proposed.
El zócalo de la ciudad de México: Un espacio social total
Authors: Acuña Delgado Angel
Published: September 2017

La emblemática plaza del Zócalo de la ciudad de México ha sido un espacio en el que, desde su inicio, las autoridades se ocuparon de hacer visibles el poder político o gubernamental, el religioso o eclesiástico y el económico o mercantil, con la sociedad en el centro. En la actualidad constituye un macro escenario de representación social, donde hay que llegar para hacerse ver y escuchar, donde la afirmación de la identidad nacional no está reñida con el reconocimiento y respeto de la heterogeneidad social y cultural. En base a los datos históricos y al trabajo etnográfico realizado, procuraremos mostrar que se trata de un «espacio social total», al constituir un lugar abierto a la participación de toda la gente que lo desee, sin distinción; y un lugar multifuncional que, más allá de la ciudad en donde se encuentra, conecta y hace entendible los diferentes niveles de la cultura mexicana.
Ciberfeminismo o feminismo en la red: Haciendo arqueología en Internet
Authors: García Manso Almudena , Silva e Silva Artenira
Published: September 2017

Este texto pretende repasar los aspectos más característicos del ciberfeminismo, haciendo especial hincapié en tres reflexiones marginales que están fuera de los límites de las teorías feministas: la realidad ciberfeminista como estrategia subversiva desestabilizadora de la norma de género dual; la necesidad de unión y mantenimiento de la singularidad de los ciberfeminismos y feminismos, y el apoyo en las TICs “juntas gobernaremos la galaxia…”; y la fuerza en la ontología cyborg como estrategia, imagen mítica y política de desestabilización de los géneros “duales y estandarizados”. Hablamos de arqueología, pues nos adentramos en una sima, que es toda la información en Internet, nos mostramos abiertos a recoger pistas y a deducir desde la antigüedad de esos datos, la ideología ciberfeminista desde sus orígenes. Tiempos no muy lejanos para las generaciones analógicas, pero tiempos antiguos para las generaciones “millenians”. En este trabajo nombramos metafóricamente a la arqueológica como técnica de investigación de un hecho muy antiguo. Aunque en verdad lo que queremos hacer es un recorrido por lo fue el ciberfeminismo, entendido como feminismo para internet y no feminismo en internet.
Promoviendo la apropiación del modelo de energía en estudiantes de 4º de ESO a través del diseño didáctico.
Authors: Soto Macarena , Couso Digna , López Simó Víctor , Hernández María Isabel
Published: September 2017

Presentamos una investigación sobre la apropiación del modelo de energía por parte de estudiantes de 4º de ESO que participan de un taller experimental centrado en la modelización (ideas de transferencia, conservación y degradación de la energía), identificando los grados de sofisticación en el uso del modelo y las fronteras conceptuales que superan, y usando este análisis para orientar el refinamiento iterativo del diseño del taller (perspectiva de diseño basado en la investigación). Encontramos que la mayoría de estudiantes pasan de explicar los fenómenos en términos de transformación de energía a hacerlo en términos de transferencia, y que el grado de sofisticación de sus explicaciones es substancialmente mayor después de refinar el taller. En particular, se muestran especialmente eficientes los constructos didácticos gráficos/lingüísticos que proporcionan andamiaje en la mirada a los fenómenos des del modelo de energía.

Authors: Borrachero Cortés Ana Belén , Dávila Acedo María Antonia Antonia , Costillo Borrego Emilio , Mellado Jiménez Vicente
Published: September 2017

La literatura indica que los futuros profesores, cuando comienzan sus prácticas docentes, arrastran consigo una serie de creencias, actitudes y emociones, resultado del recuerdo de sus diversos años de escolarización. Por tanto, se considera necesario que los profesores en formación reflexionen sobre las emociones que experimentan hacia las ciencias. Para ello, se diseña y se desarrolla un programa de intervención para estudiantes del Máster Universitario de Formación del Profesorado de Educación Secundaria, en las especialidades de Biología/Geología, Física/Química y Matemáticas. Los resultados demuestran que al terminar el programa, de forma general, las emociones que experimentan son positivas, existiendo una ausencia de emociones negativas. Además, su autoeficacia docente ha aumentado y saben utilizar estrategias para autorregularse.

Published: September 2017

A Geografia Cultural se interessa pela espacialização dos geossímbolos capazes de semiografar agências e territorialidades. O Sagrado pode materializar-se simbolicamente nos atos e comportamentos triviais de um grupo, como o alimentar-se, determinando a construção de identidades próprias e evocando sentidos e saberes ligados ao alimento. Neste artigo, o Kaak Al Abbas,  participa como alimento simbólico e indispensável à celebração de Ashura, marco histórico representado na Batalha de Karbala, a Tragédia responsável pela cisão jurisprudencial e política do Islam entre sunitas e xiitas.  Sua fabricação, consumo e distribuição são parte integrante do processo ritualístico anual no Brasil e no mundo, apresentando simbolismos e significados capazes de configurar identidades, demarcar poderes e erigir territorialidades. A partir de uma abordagem embasada na Geografia Cultural e na filosofia fenomenológica, pretende-se descrever e traçar algumas reflexões pertinentes sobre a alimentação no campo geográfico a partir de uma perspectiva religiosa do consumo alimentar.
Diversity and determination of wildlife ‘umbrella species’ in the Gunung Leuser National Park
Authors: Kuswanda Wanda
Published: September 2017

The determination of ‘umbrella species’ in the wildlife conservation implementation is very important to be effective and directed. This study was aimed to obtain information wildlife diversity (primates and terrestrial mammals) and ‘umbrella species’ on various type of habitats to support conservation programs in the Gunung Leuser National Park (GLNP), of Besitang Watershed, North Sumatera. The research was carried for six months, from May to October 2015. The observation was made using combination of variable circular plot and strip transect methods. Determination of 'umbrella species' is done through valuating by referring to the Department of Forestry criterias (2008). Primate were identified about 6 species and terrestrial mammal of 16 species. Primate and mammal diversity index are with the category of low to moderate with abudance index between 5.60-15.32. Based onassessment criteria and consideration to high conflict potential show that ‘umbrella species’ are elephant (Elephas maximus sumatranus Temminck, 1847). The wildlife conservation implications are recommended, such as to the elephants around GLNP, i.e to increase research wildlife distribution and population, habitat protection and population pockets, to develop a database and monitoring with geographic information systems (GIS), the minimization a hunting and law enforcement as well as mitigation wildlife conflicts, such as elephants and orangutans.

This research was carried out to examine the basic properties (anatomical structure, chemical, physical and mechanical) of agathis (Agathis hamii M. Dr.) wood from natural forest in Sulawesi. Proper uses of wood was determined by considering their basic properties and uses which the local community have currently employed. Results revealed that agathis  heartwood is whitenish to yellow brownish colour;  fine texture; straigh grain; glossy; rather soft; moderate in specific gravity; moderate in dimensional shrinkage; strenght class III; high in cellulose and pentose content; low in lignin, extractive and ash content; remarkably long fiber and thin wall thickness; fiber grade is very good for pulp/paper manufacture. Appropirate uses of agathis are for light construction material in house building and certain ship components, furniture, handicraft and wood industry.
Behavior and group movement of proboscis monkey’s (Nasalis larvatus Wurmb.) in Samboja, East Kalimantan
Authors: Atmoko Tri
Published: September 2017

Proboscis monkey (Nasalis larvatus Wurmb.) are endemic primates to the island of Borneo that are subjected to serious problems like habitat loss, fragmentation and forest degradation. Studies of movement behavior of monkeys have been done in the isolated and fragmented habitat in Samboja, East Kalimantan. Behaviour data of feeding, moving, social, resting, and sleeping were collected using instantaneous sampling method. The plots of trees survey were established 20 m x 200 m on each habitat. The movement behavior consists of daily ranging and utilization of height of the canopy. Daily ranging was recorded by GPS and height of canopy utilization divided to 0-3 m, 3.1-6 m, 6.1-9 m, 9.1-12 m, and > 12 m. The results showed that the daily ranging of the monkeys were varied, ranging from 25.7 m– 749.9 m (average 333 m), which home ranges between 4.52 ha – 6.92 ha. Daily movement distance between groups on the three habitat was different. Generally, the monkeys used canopy strata depending on habitat conditions, height, diameter and density of trees.
Reading and Learning Difficulties in English Language Among Private and Public Primary School Pupils in the Federal Capital Territory (FCT), Nigeria
Authors: Adebayo Odeniyi Olujinmi , Marian Folorunsho Gbemisola
Published: September 2017

The importance of education has often been underscored by scholars and researchers across different disciplines. Primary education is very crucial to the development of any nation. This is because of the liberating role it plays within the society. Studies have shown that when a person undergoes primary education, many problems that may constitute potential threats to the national and global well-being of a nation are solved. These problems include ignorance, illiteracy, religious violence, insecurity, and political servitude. This study investigated the reading and learning difficulties in English language among private and public primary school pupils in the Federal Capital Territory (FCT) in Nigeria. Descriptive survey research design was adopted for this study. The populations for this study are pupils of private and public primary schools in the Federal Capital Territory. It constitutes 491 primary schools in Abuja and an enrolment figure of 185,808. The study adopts multistage sampling technique which is a probability sampling technique. Data was analysed using simple percentages, frequency counts, and tables. Findings showed that primary school pupils experience some difficulties in reading and learning English language which is the medium of instruction in their schools. Some of these problems are environment induced, while others are foundational. In conclusion, the study recommends that parents must ensure they devote adequate time to help their wards develop the interest and confidence needed to achieve comprehension. Teachers need to be more strategic in the teaching of English language, especially by encouraging listening to the language first and constant practice.
The Impact of Russia’s Oil-Dominated Energy Economic Changes on the Exchange Rate of Russian Ruble – Chinese Renminbi
Authors: Wu Maoguo , Yu Yue
Published: September 2017

Russia’s economic development has a close relation with China, due to geographical and historical reasons. This paper investigates whether the ruble – renminbi exchange rate changes accordingly when the pillar industry of Russia is drastically changing, and how the exchange rate changes and how it affects Russia’s economic development. In this paper, data of 7 variables spanning 122 months are selected based on related literature and availability of data. Regression analysis and empirical tests are carried out consequently. The results show that the energy price index represented by oil prices is negatively correlated with the exchange rate, and the explanatory power is as high as 41.1%. Following basic arbitrage methods and strategies, this paper verifies the feasibility of using arbitrage by comparing actual exchange rates with forecasted exchange rates. According to empirical results, problems witnessed in the process of ruble internationalization provides policy implications for China. China’s economy is utilized as an example to discuss the shortcomings of Russia’s economy. Related solutions are proposed.

Published: September 2017

This study was conducted to find out the perception of the television audience on how the Nigerian Television Authority (NTA) and the Channels Television have so far reported the abduction of over 200 female students at Government Girls Secondary School in Chibok, Borno State of Nigeria. The survey research method was used to carry out the study while the questionnaire served as the measuring instrument. The residents of South- East Nigeria constituted the population of the study from where a sample of 384 was drawn using the creative research systems online sample size calculator. Multi-Stage sampling technique was used to select specific local government areas, wards and households that were studied. Findings revealed that NTA’s reports on the abduction of the Chibok school girls are often in favour of government while Channels Television’s reports on the abduction are often balanced. The credibility level of NTA’s reports on the abduction of the Chibok school girls was rated low while that of Channels Television was highly rated. Based on the findings, it was recommended amongst others that the Nigerian Television Authority (NTA) must wake up and endeavour to properly give account of the girls’ abduction. The report must be devoid of ethnic, religious or political sentiment. Doing this will fundamentally lead to believability, which will consequently raise the credibility level of the reports.
L'ereignis, Le Mot-Directeur De La Pensée De Heidegger
Authors: Roy-Ema Pascal Dieudonné
Published: September 2017

For over sixty years (from 1910 to 1973), Martin Heidegger carried out a work of thought which led him to create a large quantity of neologisms. It also led him to create a new use of idioms in the German language. This was regarded as a renewed vocabulary. His study bears new meanings and expresses the philosopher's work of thought and the new concepts he proposes. Among them is the Ereignis that this text proposes to question the content. The Ereignis is what makes time and being belongs to each other. It is the relationship of all the relations engendered by this co-membership. This is made possible by the difference installed at the heart of the same. Heidegger himself admitted that the Ereignis was the keyword of his whole thought since the early 1930s. It is the word-director of his thought.

The goal pursued in the present reflection is to analyze and explain the relationship of cause and effect between the persistence of armed conflicts and the issue of ethnic representation in political institutions in North-Kivu in Democratic Republic of Congo. Since the 1990s, is observed a systematic use of ethnicity in the calculations of political, economic and social actors active in the province. In addition to the question of nationality of immigrants, access to land and overpopulation, the question of representation of ethnic groups arises with acuity and remains at the center of the attitudes and behaviour of political and security actors on the ground. The elections held in the country in 2006, leading to the no representativeness of the tutsi ethnic group, have reconfigured the dominant positions available since the advent of rebellions in the country. An attempt to maintain or regain their status as, gun violence has been used by stakeholders, leading to the reactivation of the other ethnic dormant for the construction of bands armed self-defence groups. The persistence of the conflict in North Kivu in recent years would be also linked to the violent struggle triggered by members of the tutsi ethnic group in order to ensure their representation in provincial institutions of North Kivu, central Government or even in other strategic positions in the country. This gives political and security logically motivated other ethnic local to replenish the armed groups in order to address the threat of domination that tries to impose the tutsi ethnic group in North-Kivu.
