La pesca ilegal en el Parque Nacional Isla del Coco, Costa Rica
Authors: López-Garro Andrés , Zanella Ilena , Martínez Frank , Golfín-Duarte Geiner , Pérez-Montero Maikel
Published: March 2016

 Isla del Coco National Park (ICNP), Costa Rica, is renowned for its large aggregations of pelagic species, especially sharks (Carcharhinidae and Sphyrnidae), billfish (Istiophoridae) and tuna (Scombridae). The high abundance of these sought after species, attracts commercial fishing vessels that enter the protected waters of the Park. Illegal fisheries thus represent one of the biggest threats to the ecological integrity of this World Heritage Site. The ICNP dedicates important resources to protection and control via regular surveillance patrols, along the 12 nautical miles that have Marine Protected Area (MPA) status. During 2012, 2013 and between January and August 2014, 405 surveillance patrols within the MPA found 108 fishing lines, more than 13 000 hooks, seized more than 500 km of fishing line and 257 pelagic individuals. The yellowfin tuna (Thunnus albacares) was the most abundant species, representing more than 72.3 % of the total catch; seized individuals had a mean total length of 153.35±23.19 cm (Min=90 cm; Max=190 cm); which indicates that most individuals were adults. Analysis of monthly CPUE showed that the highest relative abundance of illegally caught T. albacores was between May and August of each year, with a mean relative abundance of 26.13±54.71, 11.63±23.79, 13.71±24.52 tunas per 1 000 hooks in 2012, 2013, 2014, respectively. This species had a high survival rate (nearly 80 % of the individuals found on the lines were still alive), probably due to the short fishing lines used by illegal fishermen, combined with the swift intervention of rangers. The CPUE of T. albacares found in this study is greater than records in Costa Rica’s Exclusive Economic Zone (0.74 and 0.44 per 1 000 hooks respectively). These results highlight the importance of ICNP as an aggregation site for T. albacares and the need for its effective protection. It is important that ranger intervention continue to be as rapid and effective as possible, in order to decrease the impact of illegal fishing on the marine biodiversity of the ICNP.

Authors: Correia Viviane da Costa , dos Santos Valdemir , Rodier Loïc Barbara , Ghavami Khosrow , Savastano Jr Holmer
Published: March 2016

The aim of this study was to evaluate the potential use of bamboo macro-, micro- and nanofibers as reinforcement in organic and inorganic matrices. Macrofibers were obtained from bamboo culms, microfibers were produced by organosolv pulping, and nanofibrillated cellulose was obtained by a grinding process. The results showed that after pulping of macrofibers, the crystallinity index increased by 16% and the amount of lignin, hemicellulose and extractives decreased by 42, 33 and 84% respectively. Furthermore, after nanofibrillation the crystallinity index of the pulp decreased by 6·7%; the thermal stability also decreased. After pulping, the thickness of the bamboo fibers was reduced by a factor of 13, while after nanofibrillation the thickness was reduced by a factor of 1222. According to the results of the mechanical characterization of the bamboo fibers carried out on macro-, micro- and nanofibers, bamboo can be used as a reinforcement in organic and inorganic matrices.

Esclerose múltipla (EM) é uma doença crônica e incapacitante do sistema nervoso central (SNC) que cursa com períodos variáveis de piora e melhora, e evolui com o acumulo de déficits neurológicos e para incapacidade. Biomarcadores, segundo a definição do Biomarkers Definition Working Group, 2001 é a característica objetivamente medida e avaliada como um indicador de um processo biológico, patogênico, ou resposta a uma intervenção terapêutica. Trata-se de um estudo de caso que permitiu compreender que um dos marcadores mais específico é os fatores neurotróficos ou neurotrofinas são proteínas produzidas pelos neurônios e pelos astrócitos. Está diretamente envolvida com o desenvolvimento, a maturação e com as funções das células nervosas. O Brain-derived neurotrophic fator (BDNF) é o fator neurotrófico mais abundante no cérebro e esta relacionado com a integridade das sinapses. Sua diminuição em indivíduos adultos associa-se com neuro-degeneração, assim como seu aumento em determinadas situações esta relacionado com reparação.

Authors: Gonzalez Juan Manuel , Restrepo Johans Steeven , Ortega Portilla Carolina , Ruden Muñoz Alexander , Sequeda Osorio Federico
Published: March 2016

Using Density Functional Theory (DFT) SiN and TiN structures were simulated, in order to study the influence of the silicon atoms insertion in the TiN lattice placed on interstitial and substitutional positions in a face centered cubic (FCC) crystalline lattice. Results showed that the SiN - FCC structure is pseudo-stable; meanwhile the tetragonal structure is stable with ceramic behavior. The TiN - FCC structure is stable with ceramic behavior similar to SiN - Tetragonal. 21% silicon atoms insertion in interstitial positions showed high induced deformation, high polarization and Si - N bond formation, indication an amorphous transition that could lead to the production of a material composed from TiN grains or nano-grains embedded in a Si - N amorphous matrix. When including 21% of silicon atoms, substituting titanium atoms, the distribution showed higher stability that could lead to the formation of different phases of the stoichiometric Ti1 -x SixNy compound.
Modelo lineal para la programación de clases en una institución educativa
Authors: Marín Ángel Juan Camilo , Maya Duque Pablo Andrés
Published: March 2016

El presente trabajo presenta un modelo de programación matemática que permite la obtención de un horario académico en instituciones de educación primaria y secundaria de diferente tamaño, cantidades de grupos y materias, considerando restricciones que frecuentemente debe enfrentar quien esta encargado del proceso de planeación. El objetivo del modelo propuesto se diferencia de aquellos encontrados en la literatura referida a este tema, ya que propende la creación de horarios maximizando la cantidad de bloques por materias, es decir asignaciones de dos horas seguidas de la misma clase, lo que favorece el proceso de aprendizaje, beneficia la agenda de los profesores al disminuir tiempos ociosos entre clases, y favorece los costos y acuerdos contractuales con la institución. El modelo es aplicado al caso particular de una institución educativa obteniendo resultados que mejoran considerablemente la calidad de la programación de clases respecto a la que actualmente está en uso. Adicionalmente, se desarrollan experimentos computacionales con instancias de mayor tamaño para validar el comportamiento del modelo, obteniendo resultados promisorios.
Reading the Book versus ‘Reading’ the Film: Cinematic Adaptations of Literature as Catalyst for EFL Students’ Critical Thinking Dispositions
Authors: Djamàa Sara
Published: March 2016

This true experimental study investigates the effect of combining the reading of literature with the ‘reading’ of film on nurturing EFL (English as a Foreign Language) students’ critical thinking dispositions in areas of truth-seeking, open-mindedness, inquisitiveness, analyticity, systematicity, confidence in reasoning, and maturity of judgment. It was conducted with 50 third year students enrolled at the department of English in Chadli Bendjedid University in Algeria. The contrast group (n=26) took two semesters of a regular literature course whereas the treatment group (n=24) took one semester of typical literature instruction and a second of a reading and viewing course. The California Critical Thinking Disposition Inventory (CCTDI) was used as both a pretest and posttest to assess participants’ overall critical thinking dispositions and scale results. Data were analyzed quantitatively using inferential statistics that included Cronbach’s alpha reliability coefficient, means, standard deviations, t-statistics and Cohen’s d effect size. Empirical findings revealed that the difference in the progress both groups manifested proved non-significant in all seven dispositions to think critically. Results’ interpretation, pedagogical implications, limitations and future research directions are examined.
The Effect of a Suggested Program Based on Interactional Metadiscourse Markers on Developing EFL Majors’ Reading Comprehension and the Reader-friendliness of Their Writing
Authors: Hassanein Osama Hassanein Sayed
Published: March 2016

This study attempted to investigate the effect of using a suggested program of interactional metadiscourse markers on EFL majors’ reading comprehension and on their reader-friendly writing. The study used a pre-test/post-test experimental and control group design. An experimental group and a control group were exposed to pre-post means of getting data (a pre-post reading comprehension test and pre-post writing test). Thirty four EFL majors at the College of Education and Arts, Northern Borders University, participated in this study. A 10-week program of interactional metadiscourse markers was developed and given to experimental group students. Results revealed a significant improvement in the reading comprehension of the experimental group students and in their reader-friendly writing. Based on these findings, it was recommended that explicit teaching of metadiscourse markers should be integrated into EFL majors’ curricula.
Mentoring as a Supportive Way for Novice Teachers in Foreign Language Teacher Development: A Case Study in an Ethnic College in China
Authors: Li Ru
Published: March 2016

Mentoring has been explored from various perspectives under different theoretical frameworks. The situation-based mentoring brings a lot of possibilities and sustainabilities to the student teachers. Given the overview on the literature of mentoring, it can be found that the research about mentoring mainly is concerned with English-speaking countries such as US and UK and populates in general teacher education. The research in subject-specific field receives scant attention, such as in Foreign Language Teacher Development (hereafter, FLTD). Finding few reports from China, especially about the novices in ethnical colleges, the empirical study running through one year from in an ethnic college shows that mentoring is a supportive way in FLTD for supporting novices. Under the framework of sociocultural theory, we found that, in addition to improving of teaching skills, mentoring can (1) lessen novices’ stress and ‘reality shock’ in teaching and strengthen the sense of belongings; (2) facilitate novice teachers’ reflection ability and (3) foster novice teachers’ self-efficacy in teaching.
Social Capitals and English Language Learning in an Iranian Language Institute
Authors: Khodadady Ebrahim , Ashrafborji Mozhgan
Published: March 2016

This study aimed to 1) explore the social capitals of students who had registered in the three branches of Khorasan Language Institute (KLI) to learn English, 2) establish their factorial validity and 3) explore their relationship with English language achievement. To this end the 40-item Social Capital Scale (SCS) developed by Khodadady and Alaee (2012) and validated with grade three senior high school students in Mashhad was modified and administered to 493 female English language learners (ELLs) in the KLI. The application of Principal Axis Factoring and Varimax with Kaiser Normalization to the collected data showed that the SCS consisted of seven factors, i.e., Social Attachment, Parental Supervision, Parental Expectation, Helpful Others, Social Contact, Religious Activities, and Parent Availability. When the SCS was correlated with the ELLs’ scores on oral and written examinations, no significant relationship could be found between social capitals and English language achievement. Out of seven factors, only Helpful Others correlated significantly but negatively with ELLs' English achievement. The results are discussed from both empirical and theoretical perspectives and suggestions are made for future research.
Role of Vocabulary Levels Test (VLT) in Chinese Undergraduate Students’ Comprehension of Textbooks
Authors: Liu Jiangfeng
Published: March 2016

Vocabulary knowledge has always been considered crucial in reading comprehension. This paper aims to link Chinese learners’ performance on Vocabulary Levels Test (VLT) to the profiling of their textbook so as to draw pedagogical implications on English teaching. The participants were 108 freshmen in Jiangsu University of Technology, China. All of them took part in the VLT, and their English textbook was profiled to see the lexical level of the vocabulary. Results showed that 81.48% of the participants had mastered the 2,000-word level, and the vocabulary of the textbook was within the vocabulary knowledge of the participants. However, results also indicated that no participants had reached the mastery level of the K-3, K-5 and AWL words. Based on the findings of the research, it was suggested that the language teacher could make use of the textbook to consolidate the participants’ K-1 to K-2 words and at the same time give them more exposure to K-3 to K5 words as well as academic words by exposing them to some extra materials.

Differentiating Multifocal Motor Neuropathy from Entrapment Neuropathy—A Diagnostic Challenge
Authors: Rison Richard A ,   Department of Neurology, Keck Medical Center of USC, University of Southern California, Los Angeles, California, US, Beydoun Said R ,   PIH Health-Whittier, Whittier, California, US
Published: March 2016

Multifocal motor neuropathy (MMN) is a rare, treatable neuropathy, but good long-term outcomes are dependent on early treatment. Appropriate diagnostic criteria exist for MMN, but it has a heterogeneous clinical presentation, and, when confined to a small group of nerves, its clinical presentation can overlap with entrapment neuropathies. Electrodiagnosis is a useful diagnostic technique but occasionally MMN can be misdiagnosed as entrapment neuropathies. Misdiagnosis should rarely occur since the nerve involvement in MMN is usually not at sites of common nerve entrapment, and the impact of misdiagnosis can be substantial. The treatments of these conditions differ significantly: intravenous immunoglobulin is the standard therapy for MMN, while treatment options for entrapment neuropathies include conservative treatment, such as splinting, corticosteroids, or surgery. Such treatment in MMN may worsen symptoms, potentially leading to progressive motor symptoms, including muscle weakness, atrophy, and significant motor disability. Two exemplary cases are presented, which highlight the importance of differential diagnosis of these conditions. Emerging technologies, such as high-resolution sonography and magnetic resonance neurography, will aid in defining future diagnostic criteria of MMN.

Published: March 2016

Although vestibular migraine is a common cause of vertigo, affecting approximately 1% of the Western world’s population, it remains widely under-recognized and is under-diagnosed. Diagnostic criteria for vestibular migraine were recently published in collaboration with the International Headache Society and the Bárány-Society. Trials investigating the treatment of vestibular migraine are sparse but some are now underway. This review focuses on the treatments options available for vestibular migraine, based on the existing evidence base where available. Regarding acute treatments, there are two randomized controlled trials that provide evidence for the use of triptans (zolmitriptan and rizatriptan) for the management of vestibular migraine attacks. For prophylactic treatment, the evidence base is largely non-existent, since the only multicenter randomized placebo-controlled trial testing metoprolol versus placebo is still underway. Consequently, the treatment recommendations for the prophylactic treatment of vestibular migraine are mainly based on expert opinion and the treatments guidelines for migraine with and without aura.
Lipid peroxidation in cardiac mitochondrial fraction of rats exposed to different supplementation with polyunsaturated fatty acids
Authors: Ketsa O.V. , Shmarakov I.O. , Marchenko M.M.
Published: March 2016

The effect of diet supplementation with polyunsaturated fatty acids (PUFAs) used at different ratios of w-6/w-3 was studied on the content of primary (diene conjugates, DC; triene conjugates, TC), secondary (ketodienes, CD; coupled trienes, CT; TBA-active products) and terminal (Schiff bases) lipid peroxidation products (LPO) and generation of superoxide anion-radical in rat heart mitochondrial fraction. It was shown that diet supplementation with high doses of w-6 or w-3 PUFAs increased the content of primary, secondary and terminal LPO in rat heart mitochondrial fraction. Llipid peroxidation was accompanied by the intensification of superoxide anion-radical generation in rat heart mitochondrial fraction. During diet consumption with the PUFAs leading factor affecting the intensity of lipoperoxidation in rat heart mitochondria is fatty acid composition, rather than the level of their saturation.
ESPÉCIES DA FAUNA URBANA DE MARABÁ E PARAUAPEBAS: CONHECER PARA PRESERVAR
Authors: Souza André Santos
Published: March 2016

O crescimento acelerado das cidades fez com que a fauna silvestre migrasse das áreas de floresta e rios para conviver cada vez mais perto dos homens. Nas cidades de Marabá e Parauapebas, dois dos maiores centros urbanos do interior do Pará, alguns vertebrados podem ser observados na área urbana, convivendo com homens, carros, máquinas e concreto. Da compilação dos mais diversos estudos de fauna realizados nessas cidades e seus entornos, constam 297 espécies de vertebrados na área urbana de Marabá, das quais 87 foram visualizadas em trabalho de observação em campo; e 275 em Parauapebas, das quais 103 foram observadas em levantamento de campo. A pesquisa percorreu os quatro cantos de cada cidade, entre os meses de maio e setembro de 2013. Os resultados do estudo apontam para a necessidade premente de dar prosseguimento a levantamentos do gênero a fim de que as espécies sejam devidamente conhecidas, posto que algumas correm risco de desaparecimento.

Published: March 2016

O presente estudo tem por objetivo analisar sob o ponto de vista microbiológico as águas do Ribeirão das Antas no Município de Cambuí-MG, como indicador de saúde e impacto ambiental. Como objetivos específicos de detectar a presença de coliformes termotolerantes e a presença da espécie Escherichia coli. A pesquisa é, também, pioneira, sendo precursora de estudos futuros para esta área e local, analisando de forma inédita o curso do rio citado. Os resultados foram comparados com os padrões previstos pelo Conselho Nacional do Meio Ambiente - CONAMA 357/05 e mostraram que o rio apresenta altos níveis de Bactérias Heterotróficas, nos pontos 3 e 4 e também elevado número de Coliformes Termotolerantes e Totais bem como a presença de Escherichia coli, nos pontos 2, 3 e 4. Esses valores são provenientes das atividades agropecuárias, lançamento de esgoto sem tratamento no rio, falta de mata ciliar entre outros.  Medidas como a coleta e tratamento de esgoto na região, e a proposta de uma conscientização ambiental da população seriam uma busca para melhoria da qualidade da água do manancial, bem como o monitoramento bacteriológico e demais parâmetros para a classificação do Ribeirão junto ao CONAMA.

Authors: Maia Priscila Barcello , Rezende Iurhy Silva , Colman Bruno Agostini , Masson Gabriele Lima , Camacho da Silva Marcos Antônio
Published: March 2016

Com um cenário bastante favorável, a expansão das áreas cultivadas com cana-de-açúcar no Estado de Mato Grosso do Sul tem tomado dimensões significativas na produção, o que torna importante o estudo de indicadores de produção dessa cultura em diversos níveis territoriais do Estado. Diante desse cenário, o objetivo deste estudo foi analisar a produção de cana-de-açúcar nos principais municípios produtores de Mato Grosso do Sul através de indicadores de produção de dados oficiais no período de 2003 a 2011. Foram utilizados dados oficiais de estimativa do LSPA/IBGE de área colhida - AC (ha), área colhida relativa - ACR (%) produção - PR (t) e produtividade média - PRM (t ha-1) em diferentes níveis territoriais (mesorregiões, microrregiões e municípios) com produção significativa de cana-de-açúcar. Na análise de agrupamento, os municípios foram tipificados quanto a AC, ACR, PR e PRM. Pela análise conjunta do agrupamento, os grupos classificados como alto e médio se assemelham ao zoneamento agroecológico da cana-de-açúcar. Através da análise de regressão a mesorregião sudoeste (MES-SU) e a microrregião de Dourados (MIC-DO) são os níveis territoriais que apresentam crescimento da PRM no período da caracterização.

Bactérias e fungos benéficos na endosfera das plantas
Authors: Barbosa Julierme Zimmer , Consalter Rangel , Vezzani Fabiane Machado , Motta Antonio Carlos Vargas
Published: March 2016

No solo, a região da rizosfera em comparação com a massa de solo apresenta marcado contraste biológico, sendo um nicho de grande densidade e diversidade de microorganismos.  Alguns fungos e bactérias benéficos ao desenvolvimento vegetal têm capacidade de colonizar o interior de plantas a partir do solo, conhecidos como organismos endofíticos. Possivelmente sejam as bactérias nodulíferas, com sua reconhecida capacidade de fixar N em leguminosas as mais conhecidas. Bactérias não nodulíferas tem a capacidade de colonizar o interior das raízes das plantas através de regiões de crescimento, em seguida, podem ser carregadas via xilema rumo à parte aérea. Podem ser encontrados em todos os órgãos vegetais, todavia, poucos estudos têm analisado as populações que transitam no continuum solo-planta até atingir caules, folhas, flores, frutos e sementes. O ultimo grupo de organismos endofíticos apresentado é o grupo dos fungos micorrízicos, esses se caracterizam como um sistema de exploração do solo paralelo ao sistema radicular que, com diâmetro extremamente reduzido conseguem minar um grande volume de solo com pequena alocação de C, o que é extremamente benéfico na aquisição de nutrientes, também podem ser benéficos em condições abióticas adversas. Em adição, alguns fungos endofíticos benéficos também podem colonizar órgãos aéreos das plantas. As interações microbiológicas que ocorrem na endosfera são altamente complexas, simultâneas e dependentes de uma série de fatores, assim seu entendimento é de fundamental importância à aplicação prática dos conhecimentos acerca de microorganismos endofíticos em agrossistemas.
La superioridad de los economistas
Authors: Fourcade Marion , Ollion Etienne , Algan Yann
Published: March 2016

Este artículo examina la posición dominante de la economía en la red de ciencias sociales en Estados Unidos. Primero documenta su insularidad relativa usando datos bibliométricos y luego analiza el rígido control desde arriba que le da su estructura jerárquica característica. Los economistas también se distinguen de otros científicos sociales por su mejor situación material, su visión del mundo más individualista y su confianza en la disciplina para resolver los problemas de mundo. Estas características constituyen lo que aquí se llama la superioridad de los economistas, cuya supremacía objetiva está ligada íntimamente a la sensación subjetiva de tener autoridad y derecho a ella. Esa superioridad alienta su intervención práctica y su gran influencia en la economía, pero también los expone a conflictos de interés, a la crítica política e incluso al ridículo.

La opinión convencional es que hay dos tipos de capital: real y financiero, que deben guardar correspondencia y que, infortunadamente, la mayoría de las veces no se corresponden, pues el crecimiento del capital financiero tiende a desajustarse y a distorsionar la acumulación de capital real. El artículo muestra que esta “tesis del desajuste” y, por tanto, la capacidad de los economistas para explicar la acumulación, se construyó sobre bases deleznables. Argumenta que no pueden medir el capital real y que las proxies que elaboran con ese propósito los enreda en circularidades lógicas e imposibilidades empíricas.

La corrupción es un fenómeno universal, pero muchas sociedades han contrarrestado sus efectos negativos mediante políticas públicas y esfuerzos sociales que promueven la transparencia y los valores sociales. Este artículo examina los arreglos microinstitucionales de las zonas mineras de Antioquia, Bolívar y Córdoba, y su relación con la corrupción. Los resultados sugieren que las reglas formales e informales y los atributos de estas comunidades desalientan la confianza entre sus miembros e incentivan las prácticas corruptas.

Authors: Joseph Jacob , Berry Kevin , Deshpande Satish P.
Published: March 2016

This study examines factors impacting ethical behavior of 182 college students in the midwestern and northwestern United States. Ethical behavior of peers had the most significant impact on ethical behavior of students. Success (in terms of grade point average) of students, and gender of the respondents, also significantly impacted ethical behavior.  Female students were significantly more ethical than their male counterparts.  Race of the respondent did not have an impact on their ethical behavior. Overclaiming scales indicated that social desirability bias did significantly impact the results of our study.  Implications of this study for researchers and practitioners are discussed.
Roadmap For A Successful Transition To An Online Environment
Authors: Borrego Jesus
Published: March 2016

Tighter budgets and lower enrollment are changing traditional higher education. The popularity of the World Wide Web (WWW) coupled with faster access to information provides an opportunity for Colleges and Universities to offer online programs. In most cases, traditional universities are not well prepared for the transition to online format and many challenges prevent a successful implementation. A common mistake made by early adopters is assuming that the migration involves two steps, namely selecting the virtual learning environment, and then porting the current classroom-based courses to the online environment. That approach often leads to failure and disappointment, not to mention lower student and faculty satisfaction. Traditional delivery of course materials is done face-to-face with students present and the student/faculty interaction promotes learning. In the online environment, learning is done in an asynchronous mode and course design has to compensate for the interaction that happens in real time during traditional courses. To properly implement online courses, an adequate technical environment must be available. If the environment is available, careful planning is essential in order to proceed. Traditional course modules require revision as they are migrated to cyberspace and should take into account the interaction among students and faculty in order to promote a quality learning process. A typical approach is to include student participation in discussion forae, but this may lead to trivial postings and students responses. In this paper, we present preconditions for a migration to online education and a roadmap to transition traditional courses to cyberspace. We also discuss methods of assessing both quantity and quality of student interaction, since this is a requirement for learning in cyberspace.
Cross-Disciplinary Faculty Perspectives On Experiential Learning
Authors: Rosenstein Alvin , Sweeney Catherine , Gupta Rakesh
Published: March 2016

An on-line survey was conducted among a universitys department chairs in an effort to gain perspective on university-wide use of Experiential Learning (EL). While there were differences in cross-disciplinary definitions and perspectives regarding EL, ninety-one per cent of 35 department chairs indicated their department made use of EL with greatest use during the junior and senior years. EL is defined generally as a hands-on experience and/or learning by doing while cognitive activity, such as observation and reflection, is included in the definition by a third of the chairs. Eighty-eight per cent of the chairs believe students view EL as either very beneficial or beneficial.
Tenured Teachers & Technology Integration In The Classroom
Authors: Cox Jerad
Published: March 2016

This article explores teachers technology integration in the classroom through 2 means: 1) what researchers are saying about emerging trends and best practices as well as, 2) the authors research assignment regarding the technology integration experiences of longer tenured teachers. More tenured teachers are different than their younger colleague in that they did not receive the same quantity of preservice technology integration instruction as part of their teacher education as their younger counterparts. Four priorities that emerged for educational stakeholders to consider in order to help transition educators from technology operators to technology facilitators and integrators (Gorder, 2008) are: 1) planning for technology, 2) addressing teacher concerns, 3) understanding and addressing the technological ability differences amongst staff, and 4) comentorship and collaboration.
Testing For The Purchasing Power Parity Hypothesis In A Small Open Economy: A VAR-X Approach
Authors: Bonga-Bonga Lumengo
Published: March 2016

This paper tests the purchasing power parity (PPP) hypothesis for the rand-US dollar exchange rate by making use of the cointegrating VAR-X approach. Given that the test of PPP hypothesis conducted in this paper involves variables of a small economy, South Africa, compared to a big economy, the US, the paper contends that traditional cointegrating VAR approach that considers all variables in a given vector as endogenous is not suitable. The results of the paper show that the restriction applied in the cointegrating vector for the VAR-X model supports the weak-form PPP hypothesis. The same restrictions are rejected in the case of traditional cointegrating VAR model. The paper concludes that it is essential to distinguish between weakly exogenous and endogenous variables in tests of the PPP hypothesis that involve small and big economies.

Finance And Poverty Reduction In China: An Empirical Investigation
Authors: Ho Sin-Yu , Odhiambo Nicholas M.
Published: March 2016

In this paper, the causal relationship between financial development and poverty reduction is examined in China, using the newly developed ARDL-Bounds testing procedure. The paper uses two proxies of financial development against private per capita consumption - a proxy for poverty reduction to examine this linkage. The results of the study show that the causal relationship between financial development and poverty reduction is sensitive to the proxy used to measure the level of financial development.When the domestic credit to the private sector (DCP/GDP) is used as a proxy for financial development, a bidirectional causality is found to prevail between financial development and poverty reduction in the short run. However, when the broad money supply ratio (M2/GDP) is used as a proxy, a bidirectional causality between financial development and poverty reduction is found to prevail in the short run, but a unidirectional causal flow from poverty reduction to financial development is found to predominate in the long run. These results show that the poverty-reduction programmes, which have been ongoing in China for decades, are likely to lead to further development of the financial sector in the long run.

A Historical Analysis Of The Post-Apartheid Dispensation Education In South Africa (1994-2011)
Authors: Mouton N. , Louw G.P. , Strydom G.L.
Published: March 2016

The period 1994-2011 introduced a new historical era for school education in South Africa. Outcomes-based Education (OBE) was introduced and was controversial from the outset for educators and policymakers alike. The reason given for the implementation of OBE was to move away from the apartheid curriculum and to address skills, knowledge and values. However, there were various shortcomings and many implementation problems that had to be addressed. Educators perceived the OBE approach to education as so problematic that it has now, finally, had to be scrapped. At this stage, the National Senior Certificate (NSC) is the exit point for school leavers and serves as a benchmark for tertiary education. Standardization is the tool used to make adjustments to Grade 12 results to correct fluctuations in performance that are the results of factors within the examination processes rather than the knowledge and abilities of candidates but this has a direct impact on the results of candidates. International benchmarking tests (e.g. TIMSS) have been introduced at the end of Grades 3, 6, and 9 to test the competency of learners in Mathematics and Science. Compared to other participating countries, the outcome for South African learners was exceedingly poor and this is seen as a reason for serious concern.
Antecedents Influencing Rugby Migration In South Africa
Authors: Pienaar Sare , Koch Karen
Published: March 2016

This study set out to determine the most important antecedents influencing the decision of players at the top five South African rugby unions to play overseas. A literature review was conducted in order to establish the theory base for the study. A survey, utilizing a self-administered questionnaire, of players at the top five South African rugby unions was conducted to determine the antecedents influencing the migration decision. The study noted financial reasons as the main antecedent in the decision to migrate. Based on players opinions, any strategy devised by the rugby unions to address the problem of player migration would have to focus on a number of facets rather than on one single area of concern.
