The application of a Business Intelligence tool for strategic planning in a higher education institution: a case study of the University of the Witwatersrand
Authors: Nyalungu Vincent
Published: June 2016

This article presents a discussion on the importance of business intelligence (BI) and the role that a specific BI tool, Business Intelligence Enterprise Edition, plays in the strategic decision-making processes in an organisation. The University of the Witwatersrand, often referred to as Wits, was used as a case study. The main objective of a business intelligence tool is to improve the quality and timeliness of the input of data to the organisational decision-making process. The quality of the data, which is an organisational asset, is therefore of the utmost importance. Approaches for the identification of business intelligence from corporate information and knowledge management were also assessed. A questionnaire was administered among key informants within the university in order to address some of the pertinent issues at higher education institutions. In addition, the role of a data warehouse within the business intelligence framework was presented. The paper itself covers a wide range of disciplines from information technology, knowledge management to decision sciences. The article also presents a proposed framework to be used in line with the best practices in the implementation of business intelligence solutions.Keywords: Business Intelligence (BI), Business Intelligence Enterprise Edition (BIEE), Data Warehouse, Strategic Decision Making, Strategic Planning, Higher Education Institutions and Knowledge Management.Disciplines: Information Technology, Knowledge Management, Management Sciences, Decision Sciences & Management
Socio-economic rights and women in South Africa: nothing but a handful of feathers?
Authors: Ingle M K
Published: June 2016

The Bill of Rights contained within South Africa’s Constitution features a number of ‘socio- economic rights’. Although these rights are justiciable they are subject to various limitations. They generally entail a positive onus on the part of the state to provide some good – not immediately, but ‘progressively’. Women have a direct interest in the realization of these rights and, where given effect to, they should exert a positive developmental impact. Some authorities are, however, of the opinion that socio-economic rights are not really enforceable. This article contends that the provision of social goods, by the state, should be the concomitant of the disciplined implementation of policy. Delivery should not therefore be contingent upon the legalistic vagaries of the human rights environment.Keywords: Socio-economic rights; justiciability; Bill of Rights; development; South African Constitution; womenDisciplines: Development Studies;Human Rights; Gender Studies; Political Science
Afrikanerliberalisme in die tydperk 1775 - 1975 – die interpretasies van GD Scholtz en H Giliomee
Authors: De Klerk P
Published: June 2016

Two historians, GD Scholtz and H Giliomee, have written extensively about liberal political thought among Afrikaners during the period 1775-1975. Their interpretations of the influence of liberalism on Afrikaner political thought differ from one another in some respects. Scholtz acknowledges the influence of the political ideas of the Enlightenment on the Cape Patriot movement of the late eighteenth century, but does not regard these ideas as a form of liberalism. He views liberalism as a political ideology alien to the Afrikaners, that was introduced to South Africa in the early 1800s by British officials and missionaries. Since the middle of the nineteenth century the main exponents of liberal political thought in South Africa were British colonists and their descendants. There were always a few Afrikaners with liberal political ideas, but they were strongly influenced by British culture or by English-speaking South Africans. Giliomee, however, is of the opinion that there were already Afrikaners with liberal ideas at the beginning of the nineteenth century. It appears from his study that, although none of the major Afrikaner political leaders from the eighteenth century until the present can be described as a liberal, in the course of two centuries a number of politicians and intellectuals with an Afrikaans background played an important role in various liberal political movements and had a significant influence on the development of Afrikaner political thought. Although Scholtz and Giliomee have both made an important contribution to research on Afrikaner liberal political thought, it is clear that more research should lead to a better understanding of this phenomenon.Keywords: South African Historiography; Afrikaner Political Thought; GD Scholtz; H Giliomee; Liberalism; Democracy; Cape Patriot Movement; Cape Franchise; Segregation; Apartheid Disciplines: Political History; Intellectual History; Political Philosophy
‘Great and lasting service to this country’: Sir Leander Starr Jameson, conciliation and the Unionist Party, 1910-1912
Authors: Mouton F A
Published: June 2016

The Jameson Raid of December 1895 estranged the two white groups in South Africa and contributed to the outbreak of the South African War of 1899-1902. With the rise of Afrikaner nationalism in the twentieth century the perception that L.S. Jameson (1853-1917) was the cause of all tension and rivalry between the two white groups became entrenched. And yet, Jameson as leader of the Unionist Party between 1910 and 1912 did his utmost to atone for the damage done by his reckless Raid. He publicly lauded Botha’s ability and integrity and this played a crucial role in diluting the anti-Afrikaner attitude of many English-speakers, convincing them to accept an Afrikaner dominated government. In addition his encouragement of a South African identity within the Empire, and his restraint on the anger and opposition to bilingualism by English-speakers supported Botha’s conciliation and nation building policies. Jameson helped to lay the foundation of a South African nation within the British Empire.Keywords: L.S. Jameson (1853-1917), Unionist Party, Jameson Raid, conciliation.

Perspectives on climate change and adaptation funding in developing countries
Authors: Lalthapersad-Pillay P , Oosthuizen A G
Published: June 2016

Most studies concur that climate change could seriously affect the sustainability and well-being of developing countries as they depend directly on climate-sensitive natural resources for their livelihood endeavours. This could primarily occur through reduced agricultural productivity, a higher incidence of diseases, the displacement of people, loss of livelihood and food price increases, all of which could contribute to food insecurity, malnourishment and escalating poverty. Although developing countries have contributed the least to Green house Gas (GHG) emissions, they stand to lose the most and it is likely that many of the development gains that have been made thus far will be reversed. To ensure that poverty reduction and economic growth do not become elusive goals for developing countries, it will be necessary to provide funds for potential adaptation measures to prevent these countries slipping further down the Human Development Index (HDI) ranking. In this paper, we will use Africa as a reference and look at the funds required for adaptation, the possible sources of funds and the conflict that may occur in prioritizing development objectives.Keywords: Climate change, sustainability, Greenhouse Gas (GHG) emissions, poverty reduction, Human Development Index (HDI)Disciplines: Economics, Environmental Studies, Sustainabiilty Studies, African Studies
Engageability: a new sub-principle of the learnability principle in human-computer interaction
Authors: Chimbo B , Gelderblom J H , De Villiers M R
Published: June 2016

The learnability principle relates to improving the usability of software, as well as users’ performance and productivity. A gap has been identified as the current definition of the principle does not distinguish between users of different ages. To determine the extent of the gap, this article compares the ways in which two user groups, adults and children, learn how to use an unfamiliar software application. In doing this, we bring together the research areas of human-computer interaction (HCI), adult and child learning, learning theories and strategies, usability evaluation and interaction design. A literature survey conducted on learnability and learning processes considered the meaning of learnability of software applications across generations. In an empirical investigation, users aged from 9 to 12 and from 35 to 50 were observed in a usability laboratory while learning to use educational software applications. Insights that emerged from data analysis showed different tactics and approaches that children and adults use when learning unfamiliar software. Eye tracking data was also recorded. Findings indicated that subtle re- interpretation of the learnability principle and its associated sub-principles was required. An additional sub-principle, namely engageability was proposed to incorporate aspects of learnability that are not covered by the existing sub-principles. Our re-interpretation of the learnability principle and the resulting design recommendations should help designers to fulfill the varying needs of different-aged users, and improve the learnability of their designs.Keywords: Child computer interaction, Design principles, Eye tracking, Generational differences, human-computer interaction, Learning theories, Learnability, Engageability, Software applications, UasabilityDisciplines: Human-Computer Interaction (HCI) Studies, Computer science, Observational Studies
The effectiveness of the Millennium Development Goals (MDG) as global paradigm shift for poverty eradication in sub-Saharan Africa
Authors: Van der Elst Herman
Published: June 2016

Despite isolated progress there seems to be no clear-cut guideline or solution to the collective eradication of extreme poverty in sub-Saharan Africa. In an attempt to overcome the above reality, the objective of the Millennium Development Goals (MDGs) is short term poverty relief to the poorest of the poor by 2015. This is to be achieved through the realisation of eight pro-poor objectives. Since 2000 there has been notable progress. Developmental organisations such as the World Bank, the International Monetary Fund (IMF) and the Freedom House Index project that global poverty will have been reduced to below fifteen per cent by 2015. The MDGs can, however, currently only be perceived as partially effective because poverty relief remains restricted to mainly Latin America and South and South East Asia. This partial success is substantiated by the reality that the majority of states in sub-Saharan Africa remains subjected to a cycle of extreme poverty, which seems impossible to overcome. There is consensus amongst many researchers that none of the MDGs will be achieved in this region by 2015.This article aims to critically analyse the nature, objectives and progress of the MDGs as a global developmental paradigm shift. In order to explore future trends and identify potential solutions, an emphasis is, however, placed on the possible reasons for the slow progress of the MDGs, specifically in sub-Saharan Africa.Keywords: Global paradigm shift, new conditionality, extreme poverty, poverty eradication, sub-Saharan Africa, foreign aid, deprivation hypothesis, weak governance, free-market approach and the poverty trapDisciplines: International relations, law, political economy, politics, environmental studies, water studies, communication studies, public management and governance, education, sociology, anthropology and history.
Key identifiers and spelling conventions in MXit-lingo as found in conversations with Dr Math
Authors: Butgereit Laurie , Botha Reinhardt A , Van den  Heever Michelle
Published: June 2016

Different human languages look different from other human languages. To use a term from the computer industry, each human language has its own “look and feel”. European English speakers can easily recognise a phrase such as “Comment allez-vous?” as being written in French while the phrase “¿Habla usted español?” is written in Spanish. Each language has its own letter frequencies, word frequencies and other identifiers. This paper describes key identifiers in MXit lingo as found in Dr Math conversations. MXit is a mobile instant messaging system which originated in South Africa and is expanding to other countries. Dr Math is a mobile tutoring system which uses MXit as a communication protocol. Primary and secondary school pupils can receive help with the mathematics homework using the Dr Math tutoring system. The pupils use MXit on their cell phones and the tutors use traditional Internet workstations. After exploring how MXit lingo is written, this paper will briefly explore why MXit lingo is written the way it is. By identifying and describing the orthographic conventions visible in the spelling of MXit lingo, although with some theoretical support, insight into the purposeful and functional nature of written, mobile communication will be revealed. In highlighting spelling that is influenced by Black South African English, an attempt will be made to contribute to the empirical development of a field of study that explores the construction of words used in South African mobile communication.Keywords: MXit, Math, letters, writing, orthographyDisciplines: Linguistics, mathematics, information technology
Academic preparedness of students – an exploratory study
Authors: Du Plessis Linda , Gerber Daleen
Published: June 2016

The high level of student failure, accompanied by an increased drop-out rate, is problematic in higher education. It is especially a concern in programmes with the subjects of Mathematics, Accounting and Science. Over many years, models of student admission and selection have been widely researched both internationally and in South Africa. Research indicates that in the academic domain, underpreparedness results from a combination of a lack of English proficiency, mathematical ability and effective study skills. In view of the above, and government policy directives to broaden access in the scarce skills areas to increase student throughput, foundation provision was introduced for students of Commerce, Information Technology, Business, Mathematics and Informatics courses at the Vaal Triangle Campus (VTC) of North-West University (NWU) in 2010. The question at that time then arose as to what criteria should be used for placing students in the extended programme. The placement of first-year students in appropriate programmes should be done with sensitivity to enhance academic success but, at the same time, should not ‘label’ students as underprepared. This paper provides perspectives on the selection criteria available for predicting academic success/preparedness, and then reports on students’ own experiences. An action research study was conducted on the academic achievement of two cohorts of first-year students at the VTC of NWU. The quantitative results of the performance of first-year students in their core modules are compared to the results of predictive tests written after admission. The results provide valuable insight into the placement of students.Keywords: Academic preparedness, extended programmes, national senior certificate, national benchmark testDisciplines: Education management studies, higher education studies
Freshlyground and the possibilities of new identities in post-apartheid South Africa
Authors: Balfour Robert
Published: June 2016

Popular music and indeed popular art forms struggle for critical attention in the academy (Larkin, 1992). Relegated to a focus on performance, or to peripheral sub-disciplines such as cultural studies, the study of popular art forms is risky terrain in higher education (Wicke, 1990). Instead, and particularly within the humanities, it has been claimed that the study of canonised art forms (Viljoen & Van Der Merwe, 2004) may enable the student to analyse a range of texts with equal skill and superior insight. This paper deals with both the popular and the interdisciplinary in relation to a theorisation of the lyrics of popular South African contemporary music group Freshlyground and the possibilities for a post-Apartheid identity explored in these lyrics through the theoretical lenses of New Historicism and Cosmopolitanism.
Project management and performance management: potential transdisciplinary contributions
Authors: Van der Waldt Gerrit
Published: June 2016

As project management and performance management as management applications gain momentum in public sector settings, the question often arise as to if, how, and when these applications should complement each other in various policy implementation and service delivery initiatives. Answers to this question should be sought from various vantage points or perspectives. These vantage points may range from macro, meso, micro as well as theoretical-methodological perspectives.The purpose of this paper is to unlock the potential for transdisciplinary contributions between Project Management and Performance Management by focusing on the methodologies, functional areas, and practical applications of both management disciplines. It is argued that the respective methodologies and their processes should be unpacked to identify the timing or moment when each discipline could, and should, make a contribution to the success of the other. This will add value to the theoretical underpinnings and practical applications of both study domains in the public sector. The respective contributions are illustrated by means of application realities of both management practices in the South African Public Service.Keywords: project management, performance management, Public Sector applications, transdisciplinarityDisciplines: project management, performance management
The descriptive properties of prescriptive theories: an application of systems thinking in data warehousing
Authors: Goede Roelien
Published: June 2016

Information systems and in particular data warehouses are very expensive systems to develop. It is therefore not advisable to experiment with ideas too different from current practices. This makes it difficult to apply prescriptive theories in an existing field. From theoretical considerations one might want to develop a data warehouse according to another method such as critical systems thinking methodology. It is however very difficult to persuade data warehouse practitioners to attempt such an experiment. This might be because they would rather adhere to known practices or that they are not sufficiently knowledgeable on critical systems thinking (or any other prescriptive theory) to apply it to such an expensive project. This paper describes a method in which prescriptive theories may be used descriptively to analyse their applicability in a specific field of application. The proposed method is used to understand the practices of the data warehouse discipline from the perspectives of the systems thinking discipline. It is also indicated how this method could be used in other studies where the behaviour of participants is viewed from a point of view of which the detail are unknown to the participants.Keywords: Data warehousing, Systems thinking, Prescriptive theory, Descriptive theory, Interpretative research.

The South African developmental landscape: restricted potentials or expansive, complex adaptive opportunities?
Authors: Burman C J , Mamabolo R , Aphane A , Lebese P , Delobelle P
Published: June 2016

This article argues that the South African developmental landscape is currently locked into an overly technical, path dependent paradigm that is unlikely to be capable of embracing the complex challenges identified by the recent National Development Plan. The article explores the internal logic of the existing path dependent, technical condition from the perspective of complexity, in the context of the Department of Science and Technology’s Fifth Grand Challenge and “continuous change”. It is argued that drawing ideas from complexity into future developmental trajectories can add value to the National Development Plan: Vision 2030, but to do so will require dynamic mind-set shifts across multiple developmental scales and interfaces if new approaches to managing development that embraces complexity, rather than denies it, is to emerge.Keywords: development; complexity; path dependency; epistemological vigilance; sense-making; National Development PlanDisciplines: Complexity Studies; Transdisciplinary studies; Management studies; Public management; Political studies; Economics; Development Studies
The usefulness of academic performance feedback to primary and secondary schools
Authors: Scherman Vanessa , Smit Brigitte , Archer Elizabeth
Published: June 2016

There has been an increased emphasis on providing schools with feedback on performance of learners with the aim of improving the quality of education. However, if feedback on learner performance is to be effectively used by schools, then it is important to understand what the informational needs of the schools are and whether schools can access the information. Thus, one research question is posed in this article namely: How can the current presentation of performance data captured in the school reports and feedback sessions be improved? The conceptual framework for the study draws on evaluation studies focusing on the use and usefulness of information. Methodologically, design research using mixed methods was employed. A needs analysis of what information was essential was undertaken. Six primary and secondary schools were purposively sampled to participate in the needs analysis from which the first prototype of the report and feedback sessions was developed. This needs analysis was comprised of interviews. The second phase included a sample of 22 primary and 21 secondary schools. Data for this phase was collected by means of Delphi questionnaires. The data was analysed using content analysis using a variety of coding strategies. One of the significant findings speaks to the view that schools felt the current content was appropriate but that individual school information could be included for the schools requesting additional information.Keywords: use, feedback, design research, nominal group technique, DELPHI questionnaires, reports, feedback sessions, supportDisciplines: education studies, further education studies, information studies

Participatory action research and the construction of academic identity among postgraduate research students
Authors: Tshelane Molaodi David
Published: June 2016

This paper discusses the construction of academic identity among postgraduate research students who emerged from a participatory action research (PAR) project. The article reports on how postgraduate research students constructed their academic identity deliberately, as they pursue their studies in a sustainable learning environment (SuLE) project. The aim is to contribute towards an understanding of the impact PAR has on research work of postgraduate students in the Faculty of Education, at the University of the Free State, in South Africa. This paper draws on the work of Yosso’s community cultural wealth to amplify how a relatively unexplored methodology in postgraduate research studies can change and contribute towards the social justice agenda, and give hope to an unequal society ruptured by apartheid. A critical emancipatory research theory of the Frankfurt school was used as the focal lens through which the literature was reviewed, together with a participatory action research process to generate data. Free attitude interviews were applied to focus groups, workshops, and meetings of Master’s and doctoral research students, as well as individual supervisory dialogues, so as to ensure the in-depth views of the construction of students’ academic identity. Video-tapes as an instrument in the generation of the data, which was transcribed into text and further analysed in line with the objectives of the study were used. Finally, a Critical Discourse Analysis (CDA) technique was used to arrive at the following findings: (i) ingenious commitment to social justice; (ii) genuine commitment to serve communities; and (iii) inter-centricity of humanity in relations.
Towards a social sustainability in higher education: Enhancing students’ solidarity and togetherness through collaborative projects in racially diverse learning environments
Authors: Ramohai Juliet
Published: June 2016

One key goal in the mission and vision statement of the University of the Free State is to recruit the best and most diverse students who work in solidarity and togetherness across social and historical divides. This goal is further echoed in the academic divisions’ own mission and vision statements which endeavour to ensure that the broader institutional goals are met. The Faculty of Education in this institution for instance, in accordance with the institution’s vision, has included in their vision statement issues of diversity and social transformation which foreground the Faculty’s commitment to produce teachers who show solidarity in their dealings with others. A question that is worth considering though is how these mission and vision statements can be implemented in practice by lecturers in their classes. In this paper I report on an action research project towards the realisation of the vision of togetherness and solidarity of the University of the Free State and the Faculty of Education, in which spaces are created for collaborative work for Honours classes. The results from this classroom practice indicate that students’ solidarity and togetherness in racially diverse learning environments can be enhanced through collaborative students’ work designed by lecturers.
The influence of selected teacher inputs on students’ academic achievement in the junior secondary school certificate mathematics in Namibia
Authors: Akpo Simon E. , Jita Loyiso C.
Published: June 2016

This study explored the link between teachers’ inputs and students’ academic achievement in the JSC Mathematics for the period 2006 to 2010. One hundred and fifty secondary schools selected from 573 secondary schools in the country constituted the target population. One hundred and sixty-four JSC mathematics teachers from the 150 secondary schools participated in the study, with the final JSC Mathematics results of the students serving as the dependent variable of the study. Mathematics teachers’ input data (academic qualifications, teaching experience and subject specialisation) were collected from a questionnaire developed by the researchers. Standard multiple regression was used to analyse the link between teachers’ inputs and students’ academic achievement in JSC Mathematics at P < 0.05and P < 0.10 respectively. The study found that teachers’ academic qualifications and subject specialisation had a significant and positive relationship with students’ academic achievement in JSC Mathematics. Teachers’ gender, however, was not significantly related to students’ academic achievement in JSC Mathematics. This is the first time within the Namibian context that we have empirically demonstrated the link between teachers’ inputs and students’ academic achievement in JSC Mathematics. The study therefore provides support for the policy initiatives that seek to link teachers’ academic qualifications, subject specialisation and teaching experience to employment and classroom allocation.
An analysis of challenges in the teaching of problem solving in Grade 10 mathematics
Authors: Moloi Tshele J
Published: June 2016

The paper focuses on challenges in the teaching of problem-solving in Grade 10 Mathematics, which may emanate from ignoring the background environment of the child (Graven & Schafer, 2013:4). It is important to affirm what learners know because their background knowledge is influenced by environmental surroundings (Leung, 2008:145), including social and cultural practices. The Department of Basic Education Report (2009) shows that the same topics in which Grade 10 Mathematics learners performed poorly corresponded with those in which they did poorly at the end of their Grade 12 examinations. The study is framed by community cultural wealth theory (Yosso, 2005), which posits knowledge as excluding communities. Rocha-Schmid (2010:344) contends that it is not correct to view excluded communities as objects for rehabilitation, but rather they should be conceived by a Freirean emancipatory project that perceives subaltern communities as authentic beings capable of engaging mathematical concepts in creative endeavours and critical thinking. Hence, the study asserts that it is crucial that parents, traditional leaders and community leaders, play a crucial role in the teaching and learning of Grade 10 Mathematics, so as to alleviate the identified challenges. The study utilised participatory action research (PAR) methods, which recognise community members as experts, and the empowerment of communities to find their own solutions to local issues (Moana, 2010:1). The researcher puts together a team of community members, the school population and education district officials as participants in the study. Each challenge was outlined and analysed using critical discourse analysis (CDA), enabling the participants to use the spoken/written word as evidence of the interpretation made at both the levels of discursive practice and social structures, to extract a deeper meaning and to make repertoires of each participant (Francis, 2012:18; Mahlomaholo, 2012a:51, 2012b:104).
The utilisation of the performances of Neil Diamond for improving the classroom practices of educators: an educational appreciation
Authors: Pretorius Jannie , Van Wyk Christo
Published: June 2016

In this research the 5D-framework of Appreciative Inquiry is used to investigate the possibility of applying the attributes and artistic strategies of the pop singer Neil Diamond for the improvement of classroom practices of educationalists. During the attendance of the performances of Diamond in 2011 in South Africa the writers and five other educationalists have identified five broad qualities and practices of Diamond. These may have application value in a school or university classroom: passionate enthusiasm, purposeful dedication, communication and interaction with the audience, refusing to conform/creating variation as well as good planning. This is the first time that the 5D-cycle has been used to study the possible utilisation of a live performance of a popular artist to facilitate the professional development of educationalists.
Intercultural communication problems relating to translation from English into Sesotho
Authors: Motsei Anastacia Sara
Published: June 2016

In this article, certain translative communication problems associated with the linguistic and stylistic differences between English and Sesotho are identified and discussed. With a view to help improve translation between the two languages where inaccurate and stilted communication frequently occurs, issues of equivalence, fidelity/faithfulness and the purpose of translation are delved into. It is furthermore argued that in South African multilingual contexts, like legal courts, criminal cases/hearings and hospitals clinics and similar health establishments, inaccurate translation and/or misinterpreting can lead to serious miscarriages of justice and poor service delivery. The reasons for such unfortunate eventualities sometimes relate to the translator-interpreter’s poor understanding of the cultural factors behind the English or Sesotho message. As such, emphasis is lain on the need for a translator-interpreter’s cultural understanding of the source language/text (SL/T) and target language/text (TL/T) to deliver an accurate version (in the target language or text – TL/T) of the original message. It is furthermore shown that one cause of social and legal injustice is closely related to the translator- interpreter’s insufficient knowledge of both the English and Sesotho culture as it exists in grammatical forms, idiomatic structures, collocation patterns and stylistic patterns of the SL/T and the TL/T.

Intestinal tuberculosis versus crohn's disease: Clinical and radiological recommendations
Authors: Sharma Raju , Madhusudhan Kumble S , Ahuja Vineet
Published: June 2016

Intestinal tuberculosis is a common clinical problem in India. The clinical features of this disease are nonspecific and can be very similar to Crohn's disease. Radiological evaluation of the small bowel has undergone a paradigm shift in the last decade. This long tubular organ that has traditionally been difficult to evaluate can now be well-visualized by some innovative imaging and endoscopic techniques. This article highlights the state-of-the-art evaluation of ulceroconstrictive diseases of the bowel and provides recommendations for the differentiation of intestinal tuberculosis from Crohn's disease.
Reduced Basis Approaches in Time-Dependent Non-Coercive Settings for Modelling the Movement of Nuclear Reactor Control Rods
Authors: Sartori Alberto , Cammi Antonio , Luzzi Lelio , Rozza Gianluigi
Published: June 2016

In this work, two approaches, based on the certified Reduced Basis method, have been developed for simulating the movement of nuclear reactor control rods, in time-dependent non-coercive settings featuring a 3D geometrical framework. In particular, in a first approach, a piece-wise affine transformation based on subdomains division has been implemented for modelling the movement of one control rod. In the second approach, a “staircase” strategy has been adopted for simulating the movement of all the three rods featured by the nuclear reactor chosen as case study. The neutron kinetics has been modelled according to the so-called multi-group neutron diffusion, which, in the present case, is a set of ten coupled parametrized parabolic equations (two energy groups for the neutron flux, and eight for the precursors). Both the reduced order models, developed according to the two approaches, provided a very good accuracy compared with high-fidelity results, assumed as “truth” solutions. At the same time, the computational speed-up in the Online phase, with respect to the fine “truth” finite element discretization, achievable by both the proposed approaches is at least of three orders of magnitude, allowing a real-time simulation of the rod movement and control.
An All-Regime Lagrange-Projection Like Scheme for the Gas Dynamics Equations on Unstructured Meshes
Authors: Chalons Christophe , Girardin Mathieu , Kokh Samuel
Published: June 2016

We propose an all regime Lagrange-Projection like numerical scheme for the gas dynamics equations. By all regime, we mean that the numerical scheme is able to compute accurate approximate solutions with an under-resolved discretization with respect to the Mach number M, i.e. such that the ratio between the Mach number M and the mesh size or the time step is small with respect to 1. The key idea is to decouple acoustic and transport phenomenon and then alter the numerical flux in the acoustic approximation to obtain a uniform truncation error in term of M. This modified scheme is conservative and endowed with good stability properties with respect to the positivity of the density and the internal energy. A discrete entropy inequality under a condition on the modification is obtained thanks to a reinterpretation of the modified scheme in the Harten Lax and van Leer formalism. A natural extension to multi-dimensional problems discretized over unstructured mesh is proposed. Then a simple and efficient semi implicit scheme is also proposed. The resulting scheme is stable under a CFL condition driven by the (slow) material waves and not by the (fast) acoustic waves and so verifies the all regime property. Numerical evidences are proposed and show the ability of the scheme to deal with tests where the flow regime may vary from low to high Mach values.
Pianure Blues: From the Dialect of the Plains to the English of the Blues
Authors: Nadiani Giovanni , Rundle Christopher
Published: June 2016

In this article the authors describe a joint performance project called Pianure Blues, in which poems in Romagnolo dialect are transposed into English and performed as blues songs, and in which songs from the Anglo-American blues/roots/folk tradition are transposed and performed as poems in Romagnolo dialect – a process they have called ‘trans-staging’. A process in which they are writers and performers and, especially, translators; translators of each other’s voices, stories, landscapes, rhythms and sounds as they look for the bond between places, languages and traditions that seem very distant from each other but which find a common mood and poetic language, a common aesthetic, in their performances. The authors reflect on the creative process involved and on the significance of establishing an intersemiotic dialogue between a ‘minority’ dialect such as Romagnolo and a ‘global’ language such as English, and the blues, have become.
Musical Metaphors in the Poetry of Wallace Stevens
Authors: Kennedy Victor
Published: June 2016

Wallace Stevens’s “The Man with the Blue Guitar” (1937) is widely recognized as one of the most important and influential poems of the 20th century. Inspired by Picasso’s painting The Old Guitarist, the poem in turn inspired Michael Tippett’s sonata for solo guitar, “The Blue Guitar” (Tippett 1983) and David Hockney’s The Blue Guitar: Etchings by David Hockney who was inspired by Wallace Stevens who was inspired by Pablo Picasso (Hockney and Stevens 1977). Central to “The Man with the Blue Guitar,” the metaphor of the musical instrument as a transformational symbol of the imagination is common in Stevens’s poems. The structure of “The Man with the Blue Guitar,” according to J. Hillis Miller, is the structure of stream-of-consciousness. Stevens’s poem creates what has been called “the deconstructed moment in modern poetry,” “an attempt to project a spatialized time that can be viewed from the privileged position of a timeless, static moment capable of encompassing a life at a glance” (Jackson 1982). This consciousness, which Derrida refers to as the “trace,” Stevens calls “the evasive movement of language.” The trace is the perception of the absence of meaning after the word or perception has passed, the glimpse of a hidden meaning that immediately vanishes. Stevens’s poem influenced not only other poets, artists and composers; references to and echoes of his ideas and techniques can be seen in popular music and culture well into the 21st century.

From today’s perspective, Alex North’s score for the 1951 film A Streetcar Named Desire, which was considered remarkable even at the time, can claim legendary status. The titles of the 16-track score suggest that the music focuses on the characters, the setting, main motifs, crucial events and states of mind. The film soundtrack could thus be denoted as integral to and harmonized with the dramatic action. This is not the case in the 2008 staging at the Slovene National Theatre in Maribor, where the music composed and selected by Hrvoje Crnić Boxer seems to focus on the protagonist only. The performance revolves around Blanche and could be interpreted as a psychoanalytic study of the play through her subconscious. Analysing the musical layers of these two considerably different productions of Williams’ play opens new interpretative aspects of this complex theatre and film classic from the Deep South literary tradition.
Eccentric Voices and the Representation of Vocal Virtuosity in Fiction: James McCourt’s Mawrdew Czgowchwz
Authors: Stawiarski Marcin
Published: June 2016

This paper examines the representation of vocal virtuosity in fiction. It focuses on the concept of voice as it is represented in a work of fiction through musical eccentricity. The paper centres on James McCourt’s Mawrdew Czgowchwz (1975). James McCourt’s novel tells the story of an opera singer, Mawrdew Czgowchwz. In the novel, the voice is related to extravagance and fanaticism, so that it relates to violence and conflict. In McCourt’s novel, the stylistic features of the text show a hyperbolic use of language resorting to Rabelaisian lists, foreign vocabulary, neologisms, or nonce-words, which create tongue-twister cornucopia effects of linguistic musicality. The paper aims to demonstrate that (a) the mode of eccentricity is a fundamental mode of representing music in literature; (b) eccentricity rubs off on the very structure of the text, so that it leads to singular forms of operatic musicalization of fiction and musicalized writing; (c) the voice ends up turning into a fetish object.

The reupholster of stained glass designs and “the deceptive silence of stolen voices”
Authors: Graves P. Nelson
Published: June 2016

Reflecting on the seminal theme of Biography as a provisional means of accessing artistic substance, this study dares a reading of the metamorphosis of the artistry of the Nigerian glass designs of Frank Ugiomoh and Nsikak Essien. Utilising an empirical analysis, principal art works of these masters are examined. However, a hermeneutic investigation is engaged to aid an unraveling of the tooling mechanisms and the art making traditions that the artists deployed in their engagement with the natural synthesis cognomen in affecting the ecclesia in Africa paradigm. The designs of Frank Ugiomoh are discussed with a hermeneutic detailing that draws attention to the peculiarities of his artistry as emblematic in the growth and development of glass designs. However, that investigation revealed (I) that the artist Nsikak Essien in re-upholstering his pictures diligently sourced his devises on mimetic reinstatements of the canons of academe; but introduced lineal schemes culled from the art forms of his Nigerian art world, specifically Uli and Nsibidi; while (II) Ugiomoh toed the intellectually subtle repositioning of themes and tooling mechanisms, declaiming the prime masters’ narratives but implanting a language of pictorial codes that deter the dearth of symbols.Keywords: biography, provisional, metamorphosis, hermeneutic, paradigm shift, re-upholster, deceptive silence of stolen voices
A contrastive study of two varieties of Onicha and the Central Igbo language
Authors: Onumajuru VC
Published: June 2016

He crux of this paper is to compare the Onicha and the Central Igbo varieties of the Igbo language. Igbo is a language spoken in south eastern Nigeria, precisely in the present Abia, Anambra, Ebonyi, Enugu, and Imo states. It is the sole language of the Igbo ethnic group of the south east states. Igbo is also a minority language of the people of Delta, Rivers, and Edo states in the present south-south geopolitical zone. It is fraught with numerous dialects which can be arranged in clusters. Some Igbo linguists recognize merely two major dialect areas, namely Onicha (Onitsha) and Owere (Owerri) on which this study is based. The objective of the paper is to present the morphosyntactic and phonological analyses of the two lects (by comparing them) in order to highlight their similarities and differences. It is observed that there are variations in the speech forms of the Central and the Onicha Igbo varieties. These variations are attested both in the lexical and the morphosyntactic domains.
Colonialism and the underdevelopment of Abuja Area of Nigeria
Authors: Unumen Julius O.
Published: June 2016

The paper examined how colonialism led to the underdevelopment of Abuja area of Nigeria. It relied on written sources, archival materials and oral interviews conducted in the area between 2005 and 2009. The materials were subjected to textual and contextual analysis before use. The theories of development and underdevelopment form the frame work of analysis in the paper. In the pre-colonial period, the economic activities of the people of Abuja area were very diverse. While some were farmers, others were engaged in trading, manufacturing, processing of agricultural produce, cloth weaving and dyeing. The diversity of economic activities stimulated trade not only within the area but also between the people and the neighbouring settlements. Colonialism destroyed their socio-economic initiatives and gave them nothing in return. In the first place, the industrial system of the area was destroyed. Again, the British colonial government neglected the area in the provision of socio-economic amenities and infrastructure such as roads, water, schools, and hospitals. It was in this regard that abject poverty reined in the area up 1976 when the capital of the country was relocated there.Keywords: Colonialism, Development, Underdevelopment, Manufacturing, Socio-economic, Amenities, Infrastructure
A critical review of concepts in liberation theology: A recipe for nation building
Authors: Allison Charles S.
Published: June 2016

Liberation theology as the name portends, has an undertone of freedom that is living on God. The word liberation, having is general and technical usage has now attached itself to movements, the theology of liberation from the 20th century. No abstract approach is needed in a complete study of this nature, because since humans are involved, aspects of social sciences and historical approach must apply in sourcing for solution. Equally important is the fact that doing a theology without recourse to God, is in itself not academic. Thus, a combination of approaches in doing theology and praises, is essential. An inevitable relationship between the church and society is paramount. While the church is supposed to maintain relevance to its geographical location; the society may not survive as an entity without the God, of the church striking the balance between these two poles in the pursuit of this study. Peaceful co-existence, political, development and modernization will emerge. The significance of liberation theology stands out clearly; on the grounds that the issues raised, become the fulcrum for nation building and nationhood.
