Mesures des risques et arbitrages réglementaires dans l'odyssée bâloise
Authors: Pop Adrian , Toader Oana
Published: November 2020

Au cours de l'histoire, la construction de la réglementation et de la supervision coordonnée des établissements bancaires internationaux est souvent apparue comme une réponse aux nombreux chocs financiers et économiques qui ont suivi les épisodes de libéralisation financière. Tandis que la définition des fonds propres est restée plutôt inchangée depuis l'accord initial de Bâle I, la mesure des risques a quant à elle subi des mutations importantes. En particulier, la sensibilité aux risques, notion clé au cœur même de la réglementation de la solvabilité bancaire, a été refondue en profondeur dans le cadre dit de Bâle II. Avec la liberté accrue conférée aux établissements bancaires, celle de pouvoir évaluer eux-mêmes le risque perçu, le régulateur a involontairement introduit des incitations adverses et laissé place à l'arbitrage réglementaire, ce qui a dès lors nuit à l'efficacité des normes de solvabilité. L'arbitrage réglementaire joue ainsi un rôle central dans la conception de la régulation prudentielle et constitue la force motrice de la dialectique réglementaire.

De la libéralisation à la gestion des flux de capitaux internationaux
Authors: Cabrillac Bruno , Marsilli Clément , Rivaud Sophie
Published: November 2020

Après l'effondrement du système de Bretton Woods, le régime de changes flottants accompagné d'une libéralisation des flux de capitaux a été adopté par la quasi-totalité des pays avancés, dès les années 1980. En revanche, cette mutation est encore en cours dans les pays émergents. Les importantes disruptions financières liées la volatilité et la procyclicité persistante des flux ont entretenu la peur du flottement et les réticences à mener à son terme ce processus de libéralisation. En outre, les deux dernières crises mondiales, de 2008-2009 et de 2020, ont montré que les sorties massives et soudaines de capitaux pouvaient être davantage liées aux cycles mondiaux qu'aux fondamentaux des pays récipiendaires. Les recommandations des organisations internationales, et notamment du FMI, se sont progressivement adaptées, gardant comme objectif de long terme une libéralisation du compte financier, mais acceptant que celle-ci puisse être réversible et intégrant, dans la boîte à outils, des politiques économiques, des mesures visant à la gestion des flux de capitaux.

Champ sonore et nouvelles pratiques d’écoute durant la Première Guerre mondiale
Authors: Tahon Benoit
Published: November 2020

Au cours de la Première Guerre mondiale, le champ sonore de la bataille s’étend bien au-delà des limites habituelles du terrain d’affrontement entre les combattants. Cette particularité, liée au développement d’armes de « destruction massive », imprime durablement un univers sensoriel qui n’est plus seulement dominé par l’usage prioritaire de la vue. Par l’intensité, la variété et la continuité de certains bombardements, la Première Guerre mondiale offre ainsi aux physiciens l’occasion de s’interroger sur la propagation du son à grande distance, sur la répartition des zones d’audition du canon ou encore sur les « zones de silence » qui interfèrent dans la géographie des sons de la guerre. Ces derniers sont par ailleurs très tôt exploités par les états-majors des pays belligérants pour en faire un auxiliaire sur le champ de batailles à des fins de repérage ou d’écoute. L’écoute rationalisée devient alors un enjeu majeur de la perception du champ de bataille et l’ouïe un instrument décisif d’appréhension et de compréhension du combat moderne.
Sign-changing solutions for a class of fractional Kirchhoff-type problem with logarithmic nonlinearity
Authors: Yang Qing , Bai Chuanzhi
Published: November 2020

In this paper, we are interested the following fractional Kirchhoff-type problem with logarithmic nonlinearity

$
\left\{ \begin{array} {ll} \left(a+b \iint_{\Omega^2} \frac{|u(x)-u(y)|^2}{|x-y|^{N+2s}} dxdy\right)(-\Delta)^s u + V(x)u = Q(x) |u|^{p-2}u \ln u^2, & {\rm in } \ \Omega, \\ u = 0, & {\rm in } \ \mathbb{R}^N \setminus \Omega, \end{array} \right.
$

where $\Omega \subset \mathbb{R}^N$ is a smooth bounded domain, $N > 2s$ ($0 < s < 1$), $(-\Delta)^s$ is the fractional Laplacian, $V, Q$ are continuous, $V, Q \ge 0$. $a, b > 0$ are constants, $4 < p < 2_s^* : = \frac{2N}{N-2s}$. By using constraint variational method, a quantitative deformation lemma and some analysis techniques, we obtain the existence of ground state sign-changing solutions for above problem.

Introduction:

Third molar impaction is a common condition associated with a high standard of living.

Aim:

The main objective of the study was to document the prevalence of mandibular third molar impactions among the Najran populace.

Materials and Methods:

This is a retrospective study reviewing computerized medical records and panoramic radiographs of patients presenting for the extraction of mandibular third molars. Ethical approval was granted from the General Directorate of Health Affairs, Ministry of Health, Najran region. Data such as demographics, indications for third molar removal, position, and pattern of third molar impaction were collected. Data were stored and analyzed using IBM SPSS software version 25 for IOS (Armonk, NY: IBM Corp).

Results and Discussion:

Amongst 6205 extractions, 1024 mandibular third molar extractions were carried out with a prevalence rate of 16.5%. There were 609 (59.5%) female and 415 (40.5%) male (F:M = 1.5:1). The age ranged from 17 to 69 years (mean ± standard deviation, 31.4 ± 9.6 years), with the majority (52.1%) in the age group of 21–30 years. One hundred and ninety-one (18.6%) of the pericoronitis cases were associated with vertical impaction, while the majority of the caries were associated with mesioangular impaction (323 [31.5%]). Mesio-angular impactions (40.8%) and Level A depth (477 [46.6%]) were the most common. Class I ramus relationship had the highest distribution (561 [54.8%]).

Conclusion:

We have reported a prevalence rate of 16.5% of impacted mandibular third molar in mostly 21–30 years of age with female preponderance. Pericoronitis was the main indication for surgical extraction.

Published: November 2020

As one of the two largest coal production and trading units in Vietnam, Vietnam National Coal - Mineral Industries Holding Corporation Limited (Vinacomin) is still operating both under the planning mechanism and the market mechanism. Additionally, in recent years, the group's coal price is also being built under these mechanisms. In the context of increasingly deep integration, fluctuating coal price and market, the competition of imported coal is getting more and more fierce, while coal mining conditions are increasingly difficult, the coal production and trading still have many shortcomings, so it is necessary to have a coal price determination mechanism accordance with the actual conditions of the Vietnamese coal market. Therefore, in order to determine the coal price scientifically and in association with practice, the reference to the coal pricing mechanism in some countries around the world to draw lessons for Vinacomin plays an important role. The content of this article mentions the coal pricing mechanism in some countries with a large amount of coal mining and consumption such as China, Australia, Russia, Indonesia,... thereby giving a comprehensive view of the coal price management, operation and construction mechanism of some coal markets in the world and as a reference basis for Vinacomin.

The article refers to the application of the Microsoft Excel Electronic spreadsheet (ME) in materials accounting. Base on the practical study of the materials accounting in the mining enterprises owned by the Vietnam Mineral Coal Industry Group (TKV) in conjunction with the study of 200/BTC-TT in 2014, the group of authors have designed the sheets to serve for the accounting of materials in the mining enterprises. In this, the sheets save the basic information about the business, the sheets of ME are designed to store the data (the inputs for materials accounting), and the sheets for the output of the material ledger. The sheets are designed with a friendly interface, complied with the regulations of the Ministry of Finance and in accordance with the actual conditions in the mining business. The functions of ME are the maximum used for the computational formulas in the ledger to ensure complete automation of writing ledger. In other words, each time the accounting document is entered in the Database, the ledger is updated immediately by using real-time processing. It is possible to say the research results of the article can be considered as a software written on the background of the ME for accounting work.

Recently with the increasing demand for isotopic materials, the development of customized refrigeration units which allows temperature stabilization, or cryostatting in the temperature range of 30…50 K became necessary. The required temperature stabilization depends on the isotope and process type and need to be performed at different temperatures. Thus, it is obvious that the development of a reliable and efficient refrigeration unit operating in the temperature range of 30…50 K is a relevant objective. This paper presents the result of a preliminary study of the cryogenic system designed for the cold production in the temperature range of 20...50 K. Structurally, the system is designed as a cascade of two refrigeration machines using a mixed refrigerant media as coolant. The Linde-Hampson refrigeration unit, which generates cold at a temperature level of about 90...100 K, is the upper high-temperature stage of the refrigeration cascade. The working fluid of the upper stage is a multicomponent zeotropic mixture of hydrocarbons. The working mixture is compressed in a hermetic lubricated compressor with a moderate compression ratio and a maximum discharge pressure of up to 30 bar. The lower "cryogenic" stage of the system implements the Bell-Coleman cycle. A three-component zeotropic mixture 2H-Ne-He is used as the working fluid of the low-temperature stage, which ensures the operability of the "cryogenic" stage of the system in the temperature range of 20...90 K. The current paper presents the design diagrams and thermodynamic cycles of the system and its elements. The rationale for selection of the refrigerant mixture and a preliminary analysis of the system components are reported.
A Case for Clinical Qualitative Research*
Authors: Chenail Ronald
Published: November 2020

For the most part, that which is called qualitative research has been developed, understood, and justified within scientific and quantitative contexts. Sharing common interests (e.g., description, interpretation, criticism, subjectivity, etc.) with this scientific qualitative research are two contrasting traditions of research and practice, which have originated and evolved in domains of inquiry other than science and technology, namely those methods and ways of knowing from the arts and humanities, and from the clinical fields. This latter type, clinical qualitative or practitioner-generated research, is defined and contrasted with the scientific and artistic varieties. A number of clinical qualitative research projects are presented from the field of family therapy, which demonstrate how clinical inquiry may be conducted from a therapist's way of acting and knowing, or may be focused on learning more about a therapist's way of practicing and thinking in the world. Finally, implications of conducting clinical qualitative research or practitioner-generated inquiry in traditional research environments is discussed.

Application of Spectral Extrapolation Technique to Stepped-Frequency RCS Measurement
Authors: Hu Chufeng , Li Nanjing , Fang Chonghua
Published: November 2020

“Time domain gating” used in the stepped-frequency radar cross section (RCS) measurement causes the inaccurate frequency domain data, especially at two ends of the band. This paper proposes a spectral extrapolation method for improving the measured RCS at two ends of the band more exactly. The core idea is: the measured frequency domain data are extrapolated to obtain the unknown value out of band with an auto-regressive model (AR model). The parameter in the AR model is calculated by the maximum entropy spectral estimation algorithm. Therefore, the span of the original band is extended, and both ends of frequency on the original band are inside the range of the new band. If the time domain gating is adding to the new band, the precision at two ends of the original band can be greatly improved. The simulation and experimental results show that more effective frequency domain data near the two ends of the band can be predicted by using the spectral extrapolation method, and the maximum error at the ends of the original band is less than 1dB after extrapolation, so it can ensure the accuracy of RCS measurement over the whole frequency band.
Design and Finite Element Analysis of a Novel Permanent Magnet Assisted Reluctance Synchronous Motor
Authors: Deng Xianming , Li Ran , Hao Lei , Zhang Ankang , Zhou Junhong
Published: November 2020

In this paper, a permanent magnet assisted synchronous reluctance machine (PMASRM) with optimized permanent magnet width and asymmetric rotor structure is proposed. A typical PMASRM is selected as the reference motor (Pre-optimized PMASRM). In order to reduce the large torque ripple of conventional PMASRM, an optimization method to
design the permanent magnet width is investigated and the Optimized Magnet-width PMASRM is proposed. On this basis, an asymmetric flux barriers structure is proposed to further reduce the torque ripple. Some electromagnetic characteristics including air-gap flux density, no-load back EMF and motor efficiency are examined by Finite Element Analysis (FEA). The simulation results show that the proposed PMASRM can not only decrease the harmonic component of no-load back EMF obviously, but also reduce the torque ripple in steady-state operation, which proves the rationality of the motor structure.

Published: November 2020

Retrodirectivity have several important applications in communication and in wireless power transfer. In this paper, frequency sensitive retrodirective transceiver is proposed. It receives a signal and infers its direction from its frequency spectrum, then it can transmit a new signal back to the same or other direction at the designer wish. To determine the direction of the coming signal, a 0.85-1.15GHz frequency scanning phased array antenna is used so that the received signal would have a distorted spectrum with the maximum amplitude frequency component linked to the direction of the signal. Based on the frequency scanning, the retrodirectivity system can be used for wireless power transfer or for reactive jamming. Special circuit is designed to receive the signal with strongest power and to isolate the frequency component with maximum amplitude. Phase-locked loop (PLL) circuit is used to link such frequency to specific phase shift that is introduced to the transmitter array antenna to send a new signal to the same direction of the received signal. ADS simulation is performed to demonstrate the performance of each block.
Practicing of Corporate Social Responsibility for Community Empowerment: A Case of a Mining Company in Indonesia
Authors: Agus Alamsyah
Published: November 2020

In recent years, Corporate Social Responsibility (CSR) has attained increased significance in both business and in the associated academic literature. The very term, CSR, clearly indicates the focus is on social responsibility as a company’s obligation to be accountable to all its stakeholders in all its operations and activities. Nowadays the concept of empowerment has become the development paradigm. The Indonesian government is expected to coordinate and be responsible for a wide range of community development activities that allow the entire community to participate actively, while the company contributes to the community empowerment process as the implementation of social responsibility undertaken through its Corporate Social Responsibility (CSR). This study assessed the CSR activities undertaken by a mining company (PT Vale Indonesia). Over the past 50 years, PT Vale Indonesia (PTVI) has been operating under the Contract of Work (CoW) agreement with the Indonesia government to open-pit nickel mines and processing plant facilities near Sorowako, Indonesia. This study provided empirical evidence on PTVI's presence benefits the surrounding communities by implementing PTVI’s CSR program called Integrated Community Development Program (ICDP). The research purpose is to explore the concept of CSR practice that is viewed and applied by PTVI to create a win-win situation that contributes to community empowerment. The findings of this case study contribute significantly to give more profound knowledge of the role of ICDP to community empowerment and to extant an understanding of the company dealing with the challenges of CSR activities for community empowerment.

Nemzetek vagy nemzetiségek? – Törvények és törvénytervezetek a nemzetiségi egyenjogúságról az 1860-as években
Authors: Csernus-Lukács Szilveszter
Published: November 2020

Apart from the relation between the Lands of the Crown of Saint Stephen and the other realms of the Habsburg Empire, the primary issue of the 1860s Hungary and Transylvania to handle was the nationality equality — accordingly, the recognitions of a nation and the language policy. As soon as the national question came into view, both the Hungarian and non-Hungarian political élites formulated their outlines on how to adjust regulations, intended to be epoch-making, regarding the national and language affairs, while the emperor temporarily coordinated the case with royal decrees until the definitive Nationality Act of 1868. The Act and its preceding drafts administered many domains regarding all branches of power, with the special role of the declaration of nations, namely the recognition of such as a legal entity, a juridicial person, which would (have) allow(ed) further entitled rights, deriving from a declaration in the era. The Hungarian and non-Hungarian acts and drafts examined in the study show decisive discrepancies regarding the number of nation(alitie)s recognized as legal entities, how the minorities were defined, and what concept of a nation each draft laid down. In my study, I examine the dissimilarities of the 5 draft plans (and the Act) made by the Hungarian élite, 8 draft plans (and acts of the 1863—1864 national assembly of Transylvania) related to the nationality political élite, draft plans and royal decrees associated to the emperor and the Royal Hungarian Lieutenancy, and a joint independence opposition — nationality draft plan.
Fiume és a nemzetiségi egyenjogúság tárgyában hozott 1868. évi XLIV. törvénycikk
Authors: Juhász Imre
Published: November 2020

Fiume (current official name: Rijeka) became part of Hungary in 1779 as a “corpus separatum”. At the time of the so-called provision, after 1870, the legal system of the port city developed in a special way. Although the Hungarian government took over the administration of the city again, this did not mean the automatic reception and application of the entire Hungarian legal system. Some Hungarian laws were not later enacted in Fiume. The article prepared on the basis of the conference lecture in Cluj-Napoca (Sapientia Hungarian University of Transylvania) intends to review the issues of legal interpretation of the applicability of Act XLIV of 1868 on National Equality by using descriptive method, taking into account legal history and legal theory aspects.
Az 1868-as nemzetiségi törvény és a magyar–horvát kiegyezés
Authors: Andrási Dorottya
Published: November 2020

The Act XXX of 1868 regulated the public law situation of Croats and Hungarians in a uniquely subdualist way within the Monarchy, and the status quo provided an appropriate basis and guarantees for further development. Another significant step in the settlement of ethnic relations within the Monarchy was Act XLIV of 1868, a law that had an organic relationship with the Compromise Act. Both the Compromise Act and the Nationality Act were defined by the public law conception represented by Ferenc Deák, the essence of which is to focus on the terminology of the unified “political nation” for the Hungarian side, and the position and rights of other national minorities were regulated in relation to it. In Deák’s understanding, the concept of the political nation was linked to the idea of the nation-state, which, as a result of domestic political changes after 1875, became increasingly nationalist and upset relations with individual nationalities, including Croats. In the long run, this process led to mutual misunderstandings between the peoples within the Habsburg Monarchy and to an explosion of ethnic and political relations as a result of several unfortunate political factors.
Pellagra: 4 D’s and 8 Points
Authors: Adrian Williams
Published: November 2020

Pellagra has largely been forgotten. This is unfortunate as important lessons are to be learnt for the diseases and social consequences of poverty (and of affluence) that often involve dietary nicotinamide and nicotinamide adenine dinucleotide (NAD) homeostasis. NAD disruption can occur not only from poor diet but from increased consumption of NAD from genotoxic and other stresses. High doses of nicotinamide lead to inhibition of NAD-consuming enzymes and excessive induction of nicotinamide-n-methyl transferase (NNMT) with consequent effects on the methylome giving a mechanism for a new hypervitaminosis-B3.
Inferring interwell connectivity in a reservoir from bottomhole pressure fluctuations of hydraulically fractured vertical wells, horizontal wells, and mixed wellbore conditions
Authors: Viet Anh Dinh , Djebbar Tiab
Published: November 2020

A technique using interwell connectivity is proposed to characterise complex reservoir systems and provide highly detailed information about permeability trends, channels, and barriers in a reservoir. The technique, which uses constrained multivariate linear regression analysis and pseudosteady state solutions of pressure distribution in a closed system, requires a system of signal (or active) wells and response (or observation) wells. Signal wells and response wells can be either producers or injectors. The response well can also be either flowing or shut in. In this study, for consistency, waterflood systems are used where the signal wells are injectors, and the response wells are producers. Different borehole conditions, such as hydraulically fractured vertical wells, horizontal wells, and mixed borehole conditions, are considered in this paper. Multivariate linear regression analysis was used to determine interwell connectivity coefficients from bottomhole pressure data. Pseudosteady state solutions for a vertical well, a well with fully penetrating vertical fractures, and a horizontal well in a closed rectangular reservoir were used to calculate the relative interwell permeability. The results were then used to obtain information on reservoir anisotropy, high-permeability channels, and transmissibility barriers. The cases of hydraulically fractured wells with different fracture half-lengths, horizontal wells with different lateral section lengths, and different lateral directions are also considered. Different synthetic reservoir simulation models are analysed, including homogeneous reservoirs, anisotropic reservoirs, high-permeability-channel reservoirs, partially sealing barriers, and sealing barriers.The main conclusions drawn from this study include: (a) The interwell connectivity determination technique using bottomhole pressure fluctuations can be applied to waterflooded reservoirs that are being depleted by a combination of wells (e.g. hydraulically fractured vertical wells and horizontal wells); (b) Wellbore conditions at the observations wells do not affect interwell connectivity results; and (c) The complex pressure distribution caused by a horizontal well or a hydraulically fractured vertical well can be diagnosed using the pseudosteady state solution and, thus, its connectivity with other wells can be interpreted.
Production technology solutions to enhance heavy oil recovery of marginal fields, offshore Vietnam
Authors: Quoc Viet Tran , Viet Hung Vu , Hai An Nguyen
Published: November 2020

The finding of heavy oil at Dong Do field of Cuu Long basin is a success in exploration. It could be considered as a large heavy oil field offshore Vietnam. Maximising reserve is a challenge to the operator when they think of a suitable development strategy to efficiently and economically exploit the field. Over the past decades, production technology application in heavy oil production has been widely developed in the industry. Apart from the thermal method, pumping technology makes remarkable advances by enlarging the drawdown created over the conventional gas lift in several heavy oil projects.

This paper presents all the production technology solutions that apply to the marginal heavy oil field offshore Vietnam. One of the major solutions is the electric submersible pump (ESP) and gas-lift (GL) combination method to enhance the wellbore lifting efficiency. In doing so, a series of solutions to improve heavy oil recovery have been conducted from design to pilot test whilst optimising the economic yield over the field life. Among them, the application of ESP and GL combination plays as the key driver to reinforce good production performance.

As a result, the design includes an electrical pump system coupled with GL back-up, all integrated with one to boost production and prolong well life. Beside that, closely monitoring and optimising is one factor to give the pump a longer life.

Published: November 2020

This paper presents the study results on the fabrication of a structural integrity assessment apparatus by determining stress concentration zones in pressure pipeline and equipment. The apparatus uses a triaxial magnetic field sensor to measure magnetic field components in three axes Ox, Oy, and Oz, in the working range of the magnetic field from -300 µT to 300 µT. The investigation of the selfmagnetic leakage field by this apparatus in the API 5L steel specimens under tensile stress shows a high variation of the magnetic field at a steel elongation lower than 1 mm (corresponding to the elastic deformation state of the material). In the case of an artificial defect, the apparatus can detect a change in the magnetic field caused by stress concentration.

Published: November 2020

The fourth industrial revolution (Industry 4.0) with the breakthrough of internet and artificial intelligence has had a strong impact, changing all aspects of global socio-economic life. Digital transformation in the spread of Industry 4.0 is no longer a choice but has become an inevitable development trend for businesses to truly stand up to the times. Digital transformation is the transformation of business activities, processes, products, and models to fully leverage the opportunities of digital technologies, characterised by development, growth, innovation, and disruption. In particular, "digital disruption" is the situation when new technology competes with the traditional business way that we now often refer to under the concepts of cloud computing, big data, and internet of things (IoT). This competition will help businesses utilise digitised data and processes to create a new model that is more efficient and convenient. Digital technologies in oil and gas companies can have a significant business impact as it contributes to increasing hydrocarbon recovery, ensuring safety across the business ecosystem, and improving operational reliability. This paper addresses the oil and gas industry’s trends in digital transformation and the initiatives at Bien Dong POC.

As teorias sobre a existência de receptores adrenérgicos foram descritas na literatura em meados da década de 40, sendo reconhecido anos depois que a inibição do sistema nervoso simpático por um determinado composto bloqueador beta adrenérgico poderia beneficiar pacientes com arritmias cardíacas e angina pectoris. Nasceram aí as primeiras substâncias bloqueadoras beta adrenérgicas não seletivas, destacando-se o propranolol. Desde então, centenas de bloqueadores betaadrenérgicos (BB) foram sintetizados e dezenas estão disponíveis em todo o mundo para uso clínico. Os mecanismos farmacológicos dos BBs são múltiplos e variam principalmente de acordo o predomínio de ação nos receptores adrenérgicos e com a lipossolubilidade, entre outros. De maneira geral, ligam-se e produzem um antagonismo competitivo e reversível nos receptores distribuídos pelo organismo. Os principais mecanismos fisiopatológicos propostos para explicar a ação medicamentosa dos BBs na hipertensão arterial sistêmica são redução do débito cardíaco, da resistência vascular periférica, do tônus vasomotor e do volume plasmático, inibição de renina, efeitos no sistema nervoso central, melhoria na adesão vascular e redefinição dos níveis de barorreceptores. Atualmente, os BBs não são preconizados como primeira linha de tratamento de hipertensão arterial sem complicações, porém eles são particularmente úteis para o tratamento da hipertensão na presença de algumas comorbidades não cardiovasculares, como a enxaqueca e o tremor essencial. Além disso, os BBs ganham destaque especial em situações cardiovasculares específicas, como angina sintomática, taquiarritmias, pós infarto agudo do miocárdio, insuficiência cardíaca com fração de ejeção reduzida e como alternativa aos inibidores da ECA ou BRA em mulheres hipertensas mais jovens que planejam engravidar. Vale ressaltar que em algumas destas situações os BBs passam a ter indicação mandatória, mesmo que não associadas à hipertensão arterial.

Practitioner research in preservice teacher education and the promotion of teacher autonomy
Authors: Heim Katja , Gabel Stephan
Published: November 2020

In this chapter, the authors describe project based learning for preservice teachers that is designed to promote Action Research and Reflective Practice to enable teachers become more active and autonomous shapers of learning and not just deliverers of curriculum content. This chapter provides an insight into the Low-Threshold Practitioner Research that they carry out with their ELT students in their respective university-based teaching contexts. The projects that they supervise are realised during long-term school placements, which are a compulsory part of students’ Master of Education programme in the federal state of North Rhine-Westphalia, Germany. By introducing the ELT students to the ideas of Action Research (e.g. Burns, 1999, Mertler, 2017) and Exploratory Practice (e.g. Allwright, 2005; Hanks, 2017), Heim and Gabel aim to empower them not only to take charge of their own professional development, so that they are not reduced to “passive receivers of curricula” (Barnes, 1976, p. 188), but also to contribute to shaping the whole “educational landscape” (Vaughan & Burnaford, 2016, p. 290) in the long run. The authors are convinced that it takes these kinds of independent teachers to create a culture of English language teaching in which more and more responsibility is handed over to learners (Little et al., 2017). As is argued later in the chapter, this will not only be true if the ELT students’ projects explicitly focus on aspects of learner autonomy in the classroom. The authors will argue that involving learners in joint discussions and decisions on any given aspect of classroom teaching, e.g. the aspect of classroom discourse, in itself already is a vital step towards learner and teacher autonomy.
SERVICE QUALITY AND CUSTOMER ACCEPTABILITY AT THE CAPE COAST BRANCH OF METRO MASS TRANSIT LIMITED

Published: November 2020

The paper seeks to examine customer’s perception about the state of public transport in Ghana; assess the extent to which customers are satisfied with Metro Mass Transport’s(MMT)public bus service delivery; and further establish the relationship (if any) among service quality, customer satisfaction, and customer loyalty. A quantitative approach, using questionnaires, was adopted to survey 377 regular students from the University of Cape Coast, who mostly patronize public transport services, especially on vacations, public holidays and school reopening seasons. Data were analyzed, using descriptive statistics and Pearson’s product-moment correlation technique. The findings indicate that the respondents’ strongest perception of the state of public transportation was its importance to society. Majority of the respondents were generally dissatisfied with MMTsservice delivery; and empirically, there was a weak, negative correlation between customer satisfaction in terms of service quality and customer loyalty. It is recommended that Metro Mass Transit Limitedmanagement focuses on some quality variables such as safety-comfort-cleanliness; information-communication; accessibility; terminal and stop points performance; and online performance, in order to improve and sustain customer loyalty.
Modelling Fiscal Sustainability in the Middle East and North African Region
Authors: Tweneboah George , Agyapong Daniel
Published: November 2020

This paper assesses the sustainability of fiscal policies in a panel of eight Middle East and North African countries over the period 1990 – 2010. Employing recent panel unit root and co-integration techniques, we find that fiscal policies are consistent with inter-temporal budget balance in accordance with the present value approach. The Pooled Mean Group estimator shows that there was no significant causality between government revenues and expenditures in the short-run. However, there is a long-run fiscal synchronization which demonstrates that fiscal sustainability strategies should aim at increasing revenues and cutting spending concurrently to avoid fiscal deficits and its attending problems such as high taxation, reduced savings and investments.
Contributions of Research Collaboration to Innovation across Disciplines
Assessing the Entrepreneurial Role of Two Ghanaian Universities
Authors: Benneh Mensah Mavis Serwah
Published: November 2020

On the basis of debates in literature on the usefulness of research from different disciplines to innovation, this study sought to assess the extent to which research collaboration between university researchers and the carriers of innovation yield outputs that contribute to innovation. The paper analyzed data from stratified sample of academics from the Sciences, Technology, Engineering and Mathematics, the Social Sciences, and the Arts, in two Ghanaian universities with the mandate to contribute to research and innovation in Ghana. Out of 266 respondents, a minimum of 40 and a maximum of 108 multiple responses were recorded on the perceived use of collaborative research findings in various types of innovation and for problem-solving. Except for service innovation, Kruskal-Wallis tests of differences across disciplines did not reveal statistically significant differences, in the extent to which the academics perceived their collaborative research findings to have contributed to innovation. Thus, all academic disciplines can be relevant to innovation and should be given the necessary policy support.
Effect of Strategic Orientation on Performance of Star-Rated Hotels in Ghana
Authors: Owusu Dominic , Mensah Ishmael K. , Amenumey Edem K. , Dei Mensah Rebecca
Published: November 2020

The study used the resource dependency theory to determine the strategic orientation that star-rated hotels in Ghana should adopt to realize both financial and non- financial performance. Out of a population of 680 star-rated hotel managers, a sample of 248 were chosen, using the stratified random sampling technique. Self- administered questionnaires were used to solicit the views of managers of the selected star-rated hotels. In all, a total of 178 responses were retrieved and analysed, using descriptive and partial least squares in structural equation modeling. Findings of the study indicate that none of the strategic orientation types influenced financial performance. However, aggressiveness, analytic, defensiveness, futuristic and riskiness were found to rather influence non-financial performance of star-rated hotels. The study, therefore, confirms the resource dependency theory and concludes that when star-rated hotels tend to be aggressive, analytic, futuristic and risky, it influences non-financial performance. The study, therefore, recommends that managers of star-rated hotels use analytic, defensiveness, futuristic and riskiness strategic orientation to enhance non-financial performance.
Corporate Social Responsibility and Access to Finance
A Study of Firms on the Ghana Stock Exchange
Authors: Adu-Asare Idun Anthony , Gamado Joshua
Published: November 2020

This study investigates the relationship between corporate social responsibility (CSR) and access to finance, using data from companies listed on the Ghana Stock Exchange (GSE). The study adopted multiple regression in investigating the relationship between corporate social responsibility (CSR) in terms of profitability (measured by return on equity – ROE) and philanthropy (measured by corporate social responsibility disclosures – CSRED), and access to finance (measured by growth in equity, retained earnings, debt and working capital). Economic responsibility and access to finance measured by growth in retain earnings are negatively and insignificantly associated. Discretionary responsibility has positive and significantly relationship with growth in equity capital. Again, economic responsibility is negatively and insignificantly related to growth in debt stock, while discretionary responsibility is positively and significantly associated with growth in debt stock. Finally, economic responsibility is negatively related to growth in working capital, while discretionary responsibility is positively related to growth in working capital, but both cases are significant. The study encourages firms to embark on higher-level social responsibility since that can alleviate access to finance challenges faced by firms.
