Functional Imaging of Paragangliomas with an Emphasis on Von Hippel–Lindau-Associated Disease: A Mini Review
Authors: Ilias Ioannis , Meristoudis Georgios
Published: September 2017

Few reports have presented data and results on functional (i.e., nuclear medicine) imaging of paragangliomas and pheochromocytomas (PGLs/PHEOs) for von Hippel–Lindau (VHL) patients. Nuclear medicine localization modalities for chromaffin tumors can be specific or nonspecific. Specific methods make use of the expression of the human norepinephrine transporter (hNET) and vesicular monoamine transporters (VMATs) by these tumors. These permit the use of radiolabeled ligands that enter the synthesis and storage pathway of catecholamines. Nonspecific methods are not related to the synthesis, uptake, or storage of catecholamines but make use of the tumors’ high glucose metabolism or expression of somatostatin receptors. Consensuses and guidelines suggest that metastatic and sporadic PHEOs/PGLs in VHL patients (as in patients with chromaffin tumors of yet unknown genotype) should be evaluated first with 18F-dihydroxyphenylalanine (18F-DOPA) positron emission tomography/computed tomography (PET/CT). The functional imaging of second choice is 123I-metaiodobenzylguanidine (123I-MIBG) for PHEOs in VHL patients. 123I-MIBG, 68Ga-DOTATATE/DOTATOC/DOTANOC PET/CT, or 18F-fluorodeoxyglucose (18F-FDG) PET/CT can be a second choice of functional imaging for PGLs in VHL patients.

Authors: Fang Congqi , Yuan Zhijie , Yang Shuai , Zhang Junmeng
Published: September 2017

The presence of chloride ions causes reinforced-concrete (RC) bridge piers in a corrosive environment to suffer from different degrees of corrosion damage. Investigation of the seismic performance of corroded RC bridge piers using cyclic loading is therefore of great value. In total, eight RC column pier specimens were experimentally investigated for their seismic performance and the influence of steel corrosion and axial repeated loading on that performance. It was demonstrated that corrosion had a significant influence on yield strength and ultimate load-bearing capacity of the column piers. Compared with non-corroded specimens, the load-bearing capacity was 18·27% lower when the corrosion of the longitudinal steel bar was 7·16%. Axial repeated loading had no significant influence on mechanical properties of the piers. Finite-element analysis was conducted to assess the effect of different parameters on the seismic performance of the piers, including concrete strength, longitudinal reinforcement ratio, axial compression ratio, height of column and stirrup ratio. As the ratio of axial compression stress to the strength was increased from 0·1 to 0·4, the maximum load-bearing capacity was increased by 27·3% from 55 kN to 70 kN. However, the ultimate displacement was significantly decreased by 42·9% from 35 mm to 20 mm.
Optimising power grids using batteries and fuzzy control of photovoltaic generation
Authors: Lühn Tobias , Geldermann Jutta
Published: September 2017

Germany's energy turnaround is leading towards an increasing integration of photovoltaics throughout its distribution grid. As solar power generation fluctuates greatly, distribution system operators are faced with the challenge of preventing grid component overload and voltage range violations. One solution might be to integrate battery storage systems into private households and reduce active peak power at the grid connection point. Since peak shaving is often impossible with the conventional operating strategy of the storage system, solar plants must sometimes be throttled back. In this study, a fuzzy control system is introduced that reduces peak feed-in and thus also energy losses due to throttling back solar power. The system uses solar surplus and battery charge level as input parameters, and standardises them to ensure easy adjustment to different combinations of plant size and storage capacity. Load flows for a complete year were modelled using real-world measurement data, which showed that even small electrical storage capacities (<5 kWh) reduce energy losses considerably and produce only small losses in self-consumption. Thus, there is an economic benefit for plant operators which switch from a conventional to a grid-optimised operating strategy.
Thermal effects in landslide mobility
Authors: Pinyol N. M. , Alvarado M. , Alonso E. E. , Zabala F.
Published: September 2017

The paper describes a thermo-hydro-mechanical formulation to model thermally induced effects due to the irreversible work input generated during soil deformation. The model was implemented into a material point calculation procedure. The method is applied to the analysis of landslides. A simple slope stability is first analysed. Mechanical work essentially dissipates in shearing bands, which develop excess pore water pressures. The marked effect of soil permeability to control the slide motion after failure is described. Shear band thickness is also a relevant control variable. The problem posed by the non-realistic thickness of shear bands in numerical calculation is addressed by means of a numerical procedure that includes consideration of embedded shear bands where the strains are assumed to be localised. Balance equations describing local flow and thermal interactions between shear bands and the remaining material are formulated. The method is applied to model the instability and subsequent rapid motion of Vajont landslide. Calculated run-out and sliding velocity reproduce, in a satisfactory manner, field observations.
A study of the axial load behaviour of helical piles in sand by frustum confining vessel
Authors: Fateh Amir Mansour Askari , Eslami Abolfazl , Fahimifar Ahmad
Published: September 2017

Helical piles as screwed piles are a popular solution for removable or recyclable foundations that support road or offshore structures. In this study, the frustum confining vessel developed at the Amirkabir University of Technology (FCV-AUT) is used to study the axial behaviour of helical piles as the physical modelling of their apparatus. Three models of helical piles are made of hollow galvanised iron pipes (diameter of 34 mm and length of 85 cm), to which single-, double- and triple-helical plates (diameter of 70 mm) are welded. The influences of the number of helices and the geometry of the piles on failure mechanism are studied at two different densities of Babolsar sand by conducting 12 tensile and compressive loading tests in FCV-AUT. The piles are instrumented using strain gauges in order to study internal axial load distribution during pile loading. Two static analysis methods are used to verify the experimental results. The results have shown that the FCV has good performance in modelling the behaviour of helical piles under compression tests. It is also known that the shear resistance parameters of the surrounding soil are more affected by three- or multi-helix piles with higher relative densities.

Authors: Kao Wei-Fong , Hou Sen-Kuang , Huang Chun-Yao , Chao Chun-Chieh , Cheng Chung-Chih , Chen Yi-Jung
Published: September 2017

Atrial fibrillation (AF) is the most common arrhythmia. The most common diagnostic method, 12-lead ECG, can record episodes of arrhythmia from which the type and severity can be determined. The Heart Spectrum Blood Pressure Monitor (P2, OSTAR Meditech Corp.) is used to measure cardiovascular pressure change, with fast Fourier transform (FFT) analysis, to obtain the heart rate frequency variability and accurate blood pressure data. Here we compared the diagnostic efficacy of the Heart Spectrum Blood Pressure Monitor with a 12-lead ECG in patients with AF. Three measurement methods were used in this study: blood pressure, mean arterial pressure (MAP) which is calculated from individual blood pressure as constant pressure, and a constant pressure 60 mmHg, in order to analyze the heart index and compare it with simultaneous 12-lead ECG. The physician used a 12-lead ECG and the Heart Spectrum Blood Pressure Monitor simultaneously. The Heart Spectrum Blood Pressure Monitor used an FFT analysis for the diagnosis of AF; the findings were compared with the readings from the 12-lead ECG. This unblinded clinical trial was conducted at the Emergency Room of Taipei Medical University Hospital. Twenty-nine subjects with AF and 33 without AF, aged 25 to 97 years (mean: 63.5 years), were included. Subjects who had been exposed to high frequency surgical equipment during testing, those with cardiac pacemakers or implantable defibrillators, and pregnant women were excluded. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) are 96.67%, 96.88%, 96.67% and 96.88% for Method 1, 90%, 100%, 100% and 91.43% for Method 2, and 100%, 93.75%, 93.75% and 100% for Method 3, respectively. The sensitivity, specificity, PPV, and NPV for all these methods ranges between 90% and 100%, indicating that the Heart Spectrum Blood Pressure Monitor can be effectively applied to AF detection.

GLOCALIZATION OF BALINESE LANGUAGE AS OUTDOOR SIGN IN DESA ADAT KUTA BALI
Authors: Mulyawan I Wayan
Published: September 2017

As a tourist destination, Kuta has become an international village which forces the native to use more English than Balinese in their working life. One of the most visible media of communication in Kuta is in the form of out-door sign. Out-door sign is considered to be the most effective mass media communication and the study is known as Linguistic Landscapes. The focus of this study is to investigate the glocalization of Balinese language as a medium of communication in Kuta especially, on out-door signs. The data of this study were collected by taking pictures of all out-door signs in Kuta area, such as Raya Kuta St., Kartika Plaza St., Pantai Kuta St., and Legian St.. The data were classified into two main types: commercial signs and non-commercial signs. The analysis started with identification of the language use and followed by a combination of language use in all signs. The finding shows that Balinese language is only used in 43 signs out of 1132 signs. Furthermore, from the 43 signs, there are only 22 using pure Balinese, 19 signs using Indonesian with Balinese Letters, and 2 signs using a combination of Balinese and Indonesian. The conclusion of the study is that the glocalization of Balinese language is not yet achieved; in fact, Balinese language is marginalized in Bali as out-door signs.
Subjetividades y agencias que emergen en la periferia urbana: Reflexiones sobre un barrio de Valencia
Authors: Moncusí Ferré Albert
Published: September 2017

Els Orriols es un barrio popular de  Valencia reconocido por su carácter multicultural, donde se está produciendo una movilización que trata de redefinir su imagen y contrarrestar aspectos que afectan negativamente a las condiciones de vida de sus vecinos y vecinas. Este texto se acerca al caso concreto de ese barrio y esa movilización para subrayar la pertinencia y potencial de la etnografía en contextos urbanos, en especial a la hora de aprehender la emergencia de subjetividades y formas de agencia, en procesos comunitarios. La etnografía en curso pone encima de la mesa manifestaciones de subjetividades y vías de agencia como son la evocación de la memoria, la expresión de temor o miedo, proyectos de futuro, expresiones de igualación y ritualización de la comunidad barrial.

Es inútil, no os engañéis, somos lo que somos. Lejos de ser una sentencia pesimista es más bien, bastante realista, solo que no queremos aceptarlo. Bastaría con sincerarnos con nuestro «yo» y esto es precisamente el objetivo de este opúsculo. A través del marco teórico y la disertación, se pretende incentivar una hermenéutica reflexiva en torno a cuatro conceptos con una gran carga histórica, filosófica, lingüística, ideológica, semántica, etc., “Naturaleza Humana”, “Persona”, “Mentira” y la “Verdad”. Conceptos que nos definen y explican por qué somos como somos. Se colocará el acento en la voz de origen griego λóγος «lôgos» ya que éste junto con el reemplazo del singular «yo» por su plural «nosotros», conforman la ecuación que nos permitirá evadir nuestra auto-extinción.
El travestismo y la androgenización en las fiestas de moros y cristianos. Una mirada desde la dimensión dialógica
Authors: Martínez Pozo Miguel Ángel
Published: September 2017

Resumen: Las fiestas de moros y cristianos, en las últimas décadas del siglo XX y entrado el siglo XXI, han evolucionado hacia una búsqueda de valores contemporáneos donde, poco a poco, de manera subconsciente por parte de sus protagonistas, han ido rompiendo y erradicando estereotipos pre construidos e institucionalizados e introduciendo aspectos y cambios acordes con los momentos en los que vivimos. Hoy día, la fiesta, como soporte de las artes, está íntimamente ligada a las artes escénicas y plásticas donde se establece una performance artística. A través del siguiente artículo nos introduciremos en los tipos de travestismos existentes dentro de las fiestas de moros y cristianos e incluso en la propia androgenización como parte de un engaño, simulación, simulacro o como mera necesidad de transformarse para subsistir o bien integrarse dentro de la propia fiesta.

La poesía, la antropología, el desierto: Habla el verso Saharaui
Authors: Massó Guijarro Ester
Published: September 2017

Se presenta un análisis antropológico del documental “Legna: habla el verso saharaui”, partiendo de su interés desde tres grandes perspectivas: 1) Temática/regional: se aborda la historia (precolonial, colonial y poscolonial) del Sáhara Occidental, enfatizando su carácter de antigua colonia española e incidiendo en la responsabilidad social que aún perdura al respecto; 2) Epistemológica: destaca el enfoque del documental desde los estudios poscoloniales, así como desde la teoría de la comunicación transmedia; 3) Metodológica: la cinta es un ejemplo notorio de trabajo desde la antropología visual, de un lado, y la etnografía colaborativa, de otro, ambos campos de especial actualidad en la antropología. Así, en suma, el documental resulta un material de crucial interés antropológico, además de una invaluable recopilación de conocimientos a través del lenguaje lírico del pueblo saharaui en sí mismo y, muy especialmente, del patrimonio inmaterial que constituye su acervo poético, al servicio en este caso de la lucha por la liberación que todavía libra el país del Sáhara Occidental.

En este artículo intentaremos analizar como la política de ordenamiento y represión del ayuntamiento de la ciudad de Río de Janeiro, llamada “Choque de Ordem”, ha sido impuesta en distintos sitios de la metrópoli. Intentaremos comprender su génesis, analizando las políticas de regulación y comportamiento de los ciudadanos cariocas, en un proceso de civilización, en el sentido de Elias, que ha obtenido apoyo, sobretodo de los medios de comunicación de masivos. Al mismo tiempo la regulación y la privatización de los espacios públicos ha cerrado, sobremanera, usos rebeldes y insumisos por parte de numerosos actores sociales, como vendedores de mercancía en la calle, Bailarines del carnaval, moradores callejeros, movilizaciones cívicas y sociales, etc. Comprender la “naturaleza sociológica del conflicto” (Simmel) en curso en la arena urbana, en su multiplicidad de procesos de interacciones y de mediaciones, revelará la presencia surda de disputas por la atribución de eficacia simbólica (Delgado:2003) al espacio público y a los suyos usos.

Published: September 2017

Actualmente, se están impulsando numerosas metodologías didácticas basadas en el trabajo por proyectos. En relación a ellas se identifican algunas características comunes, aunque en la práctica se conceptualizan y aplican de manera muy diversa. Las diferencias principales radican en cómo se entiende qué es un contexto idóneo y cómo se selecciona, en los objetivos de aprendizaje relacionados con los conocimientos conceptuales a construir, en la forma de concebir y aplicar un proceso de investigación y, también, en qué se entiende por actuar y cómo se promueve. En el artículo se reflexiona, en relación a estos aspectos, sobre las concepciones y prácticas desde el punto de vista de la competencia científica, y sobre lo que se sabe y sobre lo que aún son campos abiertos en didáctica de las ciencias.

Published: September 2017

Birds are useful bioindicators to habitat changes. This study aims to determine the responses of birds to habitat change at Maros-Pangkep karst area, Bantimurung-Bulusaraung National Park. The research was carried out in three disturbance degrees (core-zone, wilderness-zone, and the community-gardens), which represents minimal, middle, and high interference level.  A modified square-line method was used to observe vegetation of bird habitat. Point count method was used to observe bird population. Data of the bird habitat vegetation was analyzed using vegetation density. The difference of vegetation composition was analyzed using Sorensen-similarity index. Data of the bird was analyzed using abundance, and indexes of Shannon-Weinner diversity, Simpson dominance, Pielou evenness, and Margalef species richness. Significant differences between the number of the individual bird were tested using one-way ANOVA, Tukey-Bonferroni test. The results showed that birds living in karst were sensitive to habitat changes. Birds responded through reducing the number of individuals and species, shifting the species of bird that has high importance value index from low tolerance species to high tolerance species. Birds also responded by shifting the feeding guild that has high important value index from frugivore to frugivore-insectivore and then to granivore, decreasing the number of bird species with large body size, reducing the number of bird species that need a special location to build nest. Considering that Maros-Pangkep Karst has vital roles, scientific values, and biodiversity richness, it is necessary to involve all stakeholders to maintain its sustainability, including the establishment of entire Maros-Pangkep Karst area as the karst-landscape area.

Higher and technical education is critical to India’s aspirations of emerging as a major player in the global knowledge economy. Ladakh society for a long period experienced education given by monasteries, which at best provided basic education to the students. However, even this education was highly concentrated in Leh city and in a few monasteries. The conservative village people of Ladakh were somehow reluctant to send their children for formal education until 1981. Last decade 2001-2011 has significantly improved the literacy rates in Ladakh Division for both for both gender groups among rural and urban areas. Significant progress has been made to enroll students in the formal schools. However, net enrolment rates at middle, high and higher education levels are still, less as compared to Jammu & Kashmir overall average. The present paper examines the access, enrolments, infrastructure, quality challenges and opportunities for the higher and technical education system in Ladakh The study results depict strong need of improving higher and tertiary education in Ladakh with public-private partnership in order to have competitive edge for maintaining higher economic growth rates and improving Knowledge Development index in the region.
The Impact of Australian Consumer Price Index on the Exchange Rate of Australian Dollar - Chinese Renminbi
Authors: Wu Maoguo , Yu Yue
Published: September 2017

This paper investigates the impact of Australian consumer price index on Australian dollar - Chinese renminbi exchange rate. As two major economies in Asia Pacific, China and Australia are conducting ever-increasing volume of economic transactions. Massive Chinese investment, particularly in properties, has caused steady increase in Australian consumer price index and the exchange rate of Australian dollar - Chinese renminbi. Recent slowdown of Chinese economic growth and Chinese investment in Australia caused both Australian consumer price index and the exchange rate of Australian dollar - Chinese renminbi to fall significantly. This paper utilizes data from May 2005 to January 2016 and empirically tests the relation between Australian consumer price index and the exchange rate of Australian dollar - Chinese renminbi. In compliance with classical theories of exchange rates, empirical results find that a negative relation exists between Australian consumer price index and the exchange rate of Australian dollar - Chinese renminbi.

Authors: Akhigbe Omoankhanlen Joseph , Gail Oyam-Jajaboma
Published: September 2017

Job burnout and organizational cynicism are two intertwined phenomena which have adverse effects on organizations. The main purpose of this study is to examine the relationship between job burnout and organizational cynicism of employees in Nigerian Banks. The study adopted the cross-sectional survey method which is a form of the quasi-experimental research design. The study had a sample size of 214 employees drawn out from an accessible population of 499 bank employees in Port Harcourt using the Krejcie& Morgan (1970) table. The study research instruments were distributed to the accessible population using the Bowley’s (1964) population allocation formula of proportion. The Spearman rank correlation coefficient was used in testing the study hypotheses. The study findings reveal that there is a significant relationship between the two dimensions of job burnout used in this study and organizational cynicism. The study recommended among others that banks should give their employees breaks and time off from time to time in order to guide against emotional exhaustion since it has a significant relationship with organizational cynicism, this would give employees the opportunity to balance their work-life and family life. Conclusively, the study has extensively looked at the relationship between job burnout and organizational cynicism.

Profitability is one of the most important objectives of the banks. It is an evidence of the efficiency of its management and its ability to attract money and investments. The study aimed at investigating the impact of a combination of factors (Assets, Direct credit Facilities, Deposits, Owner's equity, Branches, and Automated Teller Machines (ATMs) on the profitability of banks in Jordan as measured by “Return on Assets” and “Return on Owners' equity.” The study used the Eviews program to answer questions about the study and test the hypotheses. The tool for the study was the data variables of the study for the operating banks in Jordan that were collected from the annual financial statement of the Jordanian Central Bank and Association of Banks in Jordan for the period of 2000 to 2015. The study found that there is a significant statistical impact of the factors (Assets, Direct credit Facilities, Deposits, Owner's equity, Branches, ATM) together on the return on assets (ROA). Also, there is a significant statistical impact of the factors (Assets, Direct credit Facilities, Deposits, Owner's equity, Branches, ATM) together on the return on Owners’ equity (ROE). It also recommended that the Banks in Jordan should increase diversification in the investment to increase profitability. In addition, this study pointed the need for banks to expand in electronic banking services in order to increase profits and reduce costs.

The purpose of the study was to establish the intervening effect of underwriting risk (loss ratio) on the relationship between actuarial risk management practices (ARMP) and performance of property and casualty (P & C) insurance underwriters in East Africa. Findings from primary and secondary data gathered from 82 general insurers from Kenya, Uganda and Tanzania show that there is a significant positive relationship between ARMP and non-financial performance and that loss ratio significantly mediates this relationship. The relationship with financial performance was however insignificant. The implication is that P & C insurance firms should keenly watch their loss ratios in order to improve their non-financial performance by correctly underwriting, pricing and reinsuring their risks in order to influence their claims ratio and also have a strategic claims management program in place that controls costs and leads to better firm reputation, which in turn will have ripple effect in increasing business volumes and performance. It is recommended that further empirical studies be carried out to establish other factors that especially influence financial performance.

Stakeholder involvement is critical in that it can enhance levels of ownership of the decisions made as well building trust between the governors and the governed. The purpose of the study was to investigate the influence principals’ involvement of students in decision making on student discipline in secondary schools, Kenya. The study sought to establish the areas of student involvement in decision making by secondary school principals and determine whether significant differences exist between reported incidences of student indiscipline based on the levels of student involvement in decision making in secondary schools. The study employed systems theory by Ludwig Bertalanffy which looks at organisations as systems. Schools are viewed as parts joined together by web of relationships both within and outside the school. Using a descriptive survey design with a target population of 354 secondary school principals, 300 teachers and 4602 student leaders, a sample of 118 principals and 1534 student leaders were sampled through stratified proportionate sampling. Questionnaires for principals and student leaders were used for the study. The return rate was 101 principals (85.6%) and 1433(93.4%) student leaders. Cross-tabulations were done to determine whether the mean occurrences of student indiscipline were different based on levels of principals’ involvement of students in decision making. The findings indicated that 94.1 per cent of principals involved students in decision making with varying degrees of involvement for student welfare. Analysis of Variance (ANOVA) did not indicate significant differences between involvement in decision making and lowering of cases of drug and substance abuse, cases of arson and student suspension. The incidences of student indiscipline in those schools were low, as evidenced by lowered cases of arson factor that could be attributed to  students sense of ownership and feeling respected and recognised. The study concluded that involvement in decision making is a key driver to student’s discipline. The study could be replicated in a number of counties involving teachers and Board members as respondents. In addition, the study could be replicated using mixed methods with more inclination to the qualitative research.
Risk Analysis of Shanghai Inter-Bank Offered Rate - A GARCH-VaR Approach
Authors: Wu Maoguo , Li Zeyang
Published: September 2017

The inter-bank offered rate widely used by Chinese commercial banks is Shanghai Inter-Bank Offered Rate (Shibor). Shibor has experienced significant development since it was created. It offers different products by duration. Despite its importance in China’s financial market, Shibor’s risk has largely remained unexplored. Making contribution to existing literature on risk management of Shibor, this paper investigates risk of Shanghai Inter- Bank Offered Rate (Shibor) utilizing GARCH-VaR method. The VaR of each product is calculated and compared while GARCH model is designed for a simpler calculation. In order to have a clearer view of Chinese commercial banks, the data selected is Shibor data sample from 2006 to 2016, which is measured by GARCH-VaR model and verified effectiveness by chi-square test. Empirical results show strong evidence for the need of Chinese commercial banks to change the status quo so that the great fluctuation and abnormal situation can be avoided. Policy implication, involving the interest rate management and internal problem in commercial banks, is proposed for financial regulators.

The purpose of this article is to highlight the reaction of share prices following the publication of dividends on the regional stock exchange (RSESS). To achieve the objective of our study, daily profitability series data were used over the period from January 1998 to December 2007. The methodology of the event studies was used and there are various ways to incorporate the "Event in the prices. It is accepted that the effect of the announcement of the dividend for all the securities is positive despite imperfections in the reaction of the markets. Consequently, the publication of dividends has an impact on stock market returns. The hypothetical information content of the dividend (ICHD) is therefore accepted.

In a context of massification, students of open access programs in higher education encounter more learning difficulties than their counterparts of the regulated system. In the educational literature, these learning difficulties are mainly explained by deficiencies attributable to the students; their perception is seldom taken into account. This led us to explore such difficulties from the learner's point of view in an unregulated system, namely the economics and management courses of the Mohammed V University in Rabat. This exploration was based on a discriminant analysis conducted on a sample of 122 students. The results of this study, while confirming the important role of the student's behavioral and metacognitive commitment in the learning process, emphasize the deficiencies of the institution and the professors that also explain a main part of learning difficulties. They also highlight the lack of accompaniment of learners from their pupil status to that of students which reveal the early appearance of these difficulties.

The objective of the present research is the elaboration and application of a didactic manual with communicative strategies to develop Basic English for students of the Provincial Association of the Visually Impaired of Chimborazo (APRODVICH). The didactic manual seeks to provide techniques and instruments that support the Teaching Learning process of a second language according to the specific needs of the group under study. It becomes a progressive and systematic teaching instrument consisting of six units that include vocabulary activities, basic structures and use of questions that were applied in the classroom with the accompaniment of the teacher. The research has a quasi-experimental, correlational, descriptive, explanatory, applicative, field and bibliographic design. The technique of direct observation was used with the application of checklists and questionnaires reviewed and endorsed by academic peers that allowed the evaluation of the knowledge acquired in students such as spelling, pronunciation and comprehension. The sample was evaluated in two instances—pre and post—and the results were tabulated, analyzed, interpreted and contrasted which determined the progress and significant development in pronunciation, use of the verb structure To-Be and whquestions of the English language in blind students.
Education Expenditure and Economic Growth in Mauritius: An Application of the Bounds Testing Approach
Authors: Sunde Tafirenyika
Published: September 2017

This study examines the relationship between education expenditure and economic growth in Mauritius. The study employed the ARDL bounds testing methodology for the period 1976 to 2016. The study found that education expenditure Granger causes economic growth in Mauritius in the short run. In addition, the study also found that economic growth does not Granger cause education expenditure in Mauritius in the short run. However, in the long-run, the study found that there are long run relationships between education expenditure and economic growth in both equations; and this means that an increase in either of the variables will eventually lead to an increase in the other variable. The study, therefore, found support for the hypothesis that investment in education raises economic growth. This means that Mauritius has the potential to benefit from further investments in education in the future.
Exploring the Effects of Adult and Community Education and Training on Economic Development of Women, in South Africa
Authors: Tawiah Sampson
Published: September 2017

In South Africa, Adult and Community Education and Training (ACET) is established to cater for the educationally disadvantaged individuals, especially rural women, hence, ACET programmes are running in the country nationally. One of the aims of ACET is to open economic opportunities for women; however, the majority of rural women are still performing poorly economically. This empirical study aimed to explore the effect of ACET on the economic development of women in the Lusikisiki district of South Africa. A qualitative approach in the form of a case study design was used for the study to help the researcher relate to the real life circumstances of the women. Purposive sampling was used to select 35 participants from a population of 115. The participants were selected because they had wealth of information and could explain better the phenomenon under study. Data collection instruments used were face to face individual interviews which were audio recorded with the consent of participants. The major findings of the investigation include the following: inadequate learning resources available to women; inadequate skills development programmes provided and skeptical perception of the economic benefit of ACET to women. The study suggested that the programmes of ACET should be restructured and skills driven to meet the needs of women, especially in rural communities.
