Steady-state analysis of DC converter using Galerkin’s method
Authors: Korotyeyev Igor 
Published: September 2019

Purpose
The purpose of this paper is to present the Galerkin method for analysis of steady-state processes in periodically time-varying circuits.

Design/methodology/approach
A converter circuit working on a time-varying load is often controlled by different signals. In the case of incommensurable frequencies, one can find a steady-state process only via calculation of a transient process. As the obtained results will not be periodical, one must repeat this procedure to calculate the steady-state process on a different time interval. The proposed methodology is based on the expansion of ordinary differential equations with one time variable into a domain of two independent variables of time. In this case, the steady-state process will be periodical. This process is calculated by the use of the Galerkin method with bases and weight functions in the form of the double Fourier series.

Findings
Expansion of differential equations and use of the Galerkin method enable discovery of the steady-state processes in converter circuits. Steady-state processes in the circuits of buck and boost converters are calculated and results are compared with numerical and generalized state-space averaging methods.

Originality/value
The Galerkin method is used to find a steady-state process in a converter circuit with a time-varying load. Processes in such a load depend on two incommensurable signals. The state-space averaging method is generalized for extended differential equations. A balance of active power for extended equations is shown.
Simulating swing dynamics of a power system model using nonlinear model order reduction
Authors: Singh Satyavir , Bazaz Mohammad Abid , Nahvi Shahkar Ahmad 
Published: September 2019

Purpose
The purpose of this paper is to demonstrate the applicability of the Discrete Empirical Interpolation method (DEIM) for simulating the swing dynamics of benchmark power system problems. The authors demonstrate that considerable savings in computational time and resources are obtained using this methodology. Another purpose is to apply a recently developed modified DEIM strategy with a reduced on-line computational burden on this problem.

Design/methodology/approach
On-line computational cost of the power system dynamics problem is reduced by using DEIM, which reduces the complexity of the evaluation of the nonlinear function in the reduced model to a cost proportional to the number of reduced modes. The on-line computational cost is reduced by using an approximate snap-shot ensemble to construct the reduced basis.

Findings
Considerable savings in computational resources and time are obtained when DEIM is used for simulating swing dynamics. The on-line cost implications of DEIM are also reduced considerably by using approximate snapshots to construct the reduced basis.

Originality/value
Applicability of DEIM (with and without approximate ensemble) to a large-scale power system dynamics problem is demonstrated for the first time.
Silenced by the gaps? The status of critical literacy in Scotland’s curriculum for excellence
Authors: Farrar Jennifer , Stone Kelly 
Published: September 2019

PurposeCritical literacy foregrounds the relationship between language and power by focusing on how texts work and in whose interests (Luke, 2012, p. 5). It is highlighted as an “important skill” within Scotland’s national educational framework for 3-18 year olds, the Curriculum for Excellence (CfE), yet, as this paper aims to show, what the concept means is far from clear for policy users (Scottish Government, 2009e).Design/methodology/approachUsing a lens that draws from critical discourse analysis, critical content analysis (Luke, 2001; Beachet al., 2009; Fairclough, 2010) and Ball’s method of policy analysis (2015), the authors find that the term “critical literacy” has been applied incoherently within key CfE documentation, including the frequent conflation of critical literacy with critical reading and critical thinking.FindingsThe authors argue that the CfE’s use of “critical literacy” is a misnomer, given that the version presented is an amalgamation of literacy-related competences drawing largely from psychological and not socio-political perspectives of literacy.Social implicationsThis is a missed opportunity, given the Scottish Government’s stated commitment to social justice in policy terms (Scottish Executive, 2000; Scottish Government, 2016), not forgetting the powerful benefits that a critically literate stance could bring to Scotland’s learners at this time of communicative change and challenge.Originality/valueWhile the authors offer a contextualized view of the ways in which the term “critical literacy” has been incorporated into Scottish educational policy, they propose that its implications go beyond national boundaries.
Can institutional theory be refuted, replaced or modified?
Authors: Aksom Herman , Zhylinska Oksana , Gaidai Tetiana 
Published: September 2019

Purpose
This paper aims to demonstrating that the former new institutional theory of isomorphism and decoupling cannot be extended, modified or refuted as it is a closed theory. By analyzing the structure of this former version of institutional theory and its numerous modern competitors (institutional entrepreneurship, institutional work and institutional logics theories) it is argued that these alternative theories demonstrate even less explanatory and predictive power and do not refute or extend their predecessor. The rise of new organizational theories can have no other effect on classic institutional theory than to limit the domain of its applicability. In turn, there are a number of principles and conditions that future theories should meet to be accepted as progressive advancements.

Design/methodology/approach
The paper provides a review of relevant organizational and philosophical literature on theory construction and scientific progress in organizational research and offers a set of principles and demands for those new theories that seek to challenge new institutionalism.

Findings
The authors show that the former institutional theory satisfies two main criteria that any scientific theory should conform with following it is useful and falsifiable in term of giving explanations and predictions while, at the same time, clearly specifying what can be observed and what cannot; what can happen and what is not likely to occur. Modern institutional theories cannot demonstrate this quality and they do not satisfy these criteria. Moreover, institutional isomorphism theory is a closed theory, which means it cannot be intervened with changes and modifications and all future theories should develop their theoretical propositions for other domains of applications while they should account for all empirical phenomena that institutional theory successfully explains.

Originality/value
Adopting instrumental view on organizational theories allowed reconstructing the logic and trajectory of organizational research evolution and defends its rationality and progressive nature. It is also outlined how existing dominant theory should be treated and how new theories should challenge its limitations and blind spots and which philosophical and methodological criteria should be met.

Influence of non-price incentives on the choice of cocoa licensed buying companies by farmers in the Western North of Ghana
Authors: Bannor Richard Kwasi , Oppong-Kyeremeh Helena , Atewene Samuel , Wongnaa Camillus Abawiera 
Published: September 2019

Purpose
The purpose of this paper is to examine the factors influencing the choice and the amount of cocoa beans sold to public and private licensed buying companies in the Western North of Ghana.

Design/methodology/approach
The study was conducted in the Western North of Ghana. Cragg’s Double Hurdle model was used to examine the factors influencing the choice of licensed buying company (LBC) whereas Kendall’s coefficient of concordance was employed in analysis of the marketing challenges.

Findings
The results showed that non-price incentives determine the choice and the amount cocoa beans sold to an LBC. Specifically, education, years of experience in cocoa farming and timely payment of sold cocoa beans positively influence the choice of public LBC. However, off farm job participation, provision of credit facilities and extension services affect the choice of private LBC as marketing outlet. Perceived low price of cocoa beans, inadequate credit support, and adjustment of scales used in weighing of cocoa beans were identified as the most important challenges confronting farmers.

Research limitations/implications
The research provides important information on non-price incentives influencing cocoa marketing outlet decision as well as the marketing challenges faced by farmers which can contribute to improving internal marketing efficiency of the cocoa industry in Ghana. Besides, this study also extends the frontiers in terms of methodological approach by adopting Cragg’s Double Hurdle Model in addressing the research question.

Originality/value
The research provides important information on non-price incentives influencing cocoa marketing outlet decision as well as the marketing challenges faced by farmers which can contribute to improving internal marketing efficiency of the cocoa industry in Ghana. Besides, this study also extends the frontiers in terms of methodological approach by adopting Cragg’s Double Hurdle Model in addressing the research question.
Representing search tasks in an information use environment: a case of English primary schools
Authors: Rutter Sophie , Toms Elaine G. , Clough Paul David 
Published: September 2019

Purpose
To design effective task-responsive search systems, sufficient understanding of users’ tasks must be gained and their characteristics described. Although existing multi-dimensional task schemes can be used to describe users’ search and work tasks, they do not take into account the information use environment (IUE) that contextualises the task. The paper aims to discuss these issues.

Design/methodology/approach
With a focus on English primary schools, in four stages a multi-dimensional task scheme was developed that distinguishes between task characteristics generic to all environments, and those that are specific to schools. In Stage 1, a provisional scheme was developed based upon the existing literature. In the next two stages, through interviews with teachers and observations of school children, the provisional scheme was populated and revised. In Stage 4, whether search tasks with the same information use can be distinguished by their characteristics was examined.

Findings
Ten generic characteristics were identified (nature of work task, search task originator, search task flexibility, search task doer, search task necessity, task output, search goal, stage in work task, resources and information use) and four characteristics specific to primary schools (curricular area, use in curricular area, planning and location). For the different information uses, some characteristics are more typical than others.

Practical implications
The resulting scheme, based on children’s real-life information seeking, should be used in the design and evaluation of search systems and digital libraries that support school children. More generally, the scheme can also be used in other environments.

Originality/value
This is the first study to develop a multi-dimensional task scheme that considers encompasses the IUE.
An inquiry into exchange rate misalignments as a cause of major global trade imbalances
Authors: Nasir Muhammad Ali , Jackson Karen 
Published: September 2019

Purpose
In the context of debate on competitive devaluation and trade imbalances, the purpose of this paper is to investigate the role of exchange rate misalignment as a determinant of trade imbalances in selected major trade surplus (Germany, China, Japan, Russia and KSA) and major trade deficit countries (USA, UK, France, India and Turkey).

Design/methodology/approach
The authors used a structural vector auto-regressive model on data from ten countries with the highest trade deficit and surplus. The period of analysis is from 2000 Q1 to 2016 Q1.

Findings
The key findings suggest that although exchange rate misalignment from equilibrium may have some implications for the current account balance for surplus and deficit countries, the effects observed were rather very mild and transitory. There was a heterogeneity in the response of the current account position to exchange rate misalignment in each country, concomitantly; the exchange rate misalignment shall not be seen as the sole responsible factor in the debate on global trade imbalances.

Research limitations/implications
The research has profound implications in terms of exploring the notion of competitive devaluation and exchange rate misalignment as a cause of major global trade imbalances.

Practical implications
This study has important practical implications for the trade policy of major economies in the world. These are twofold. First, this study has analysed and reported on the degree of misalignment of exchange from its equilibrium values in the major trade surplus and deficit countries. Second, it has investigated the implications of any misalignment for the trade balance or respective economies.

Social implications
There are important social implications as the notion of competitive devaluation and exchange rate–trade balance nexus has been heavily politicised. This study provides an empirical insight and an answer to these claims which have social and political implications.

Originality/value
There is a significant element of originality and contribution to the existing body of knowledge on the subject. In the context of debate on competitive devaluation this is the first study which has investigated whether the exchange rate has been misaligned from its equilibrium values (competitive devaluation) and whether there is some nexus between the real exchange rate misalignment and trade imbalances in under-analysis economies.
Gender wage gap and its effect on test scores of immigrant students
Authors: Yamamura Eiji 
Published: September 2019

PurposeThe purpose of this paper is to examine how gender equality influences difference in cognitive skills between genders. For the closer examination of Guisoet al.(2008), restricting the sample to immigrants allows us to reduce the possibility of reverse causality.Design/methodology/approachUsing PISA 2012 matched with the gender wage gap sourced from World Economic Forum’s Global Gender Index 2011, the author compares the effect of the wage gap among the areas of mathematics, science and reading.FindingsDecreased gender wage gap leads to girls exhibiting a reduced incidence of lateness and skipping school compared with boys, which in turn improves girls’ test scores in mathematics, science and reading. The direct effect of the decreased wage gap on test scores exceeds its indirect effect on performance owing to influencing school attendance.Originality/valueThe findings of this paper provide evidence that higher female wage level relative to male wage level incentivizes female students to attend school, resulting in their achieving higher test scores not only for mathematics, but also for science and reading.
Initial bank loans, zero-leverage firms and stock market liquidity
Authors: Zhang Sijia , Gregoriou Andros 
Published: September 2019

Purpose
The purpose of this paper is to examine stock market reactions and liquidity effects following the first bank loan announcement of zero-leverage firms.

Design/methodology/approach
The authors use an event studies methodology in both a univariate and multivariate framework. The authors also use regression analysis.

Findings
Using a sample of 96 zero-leverage firms listed on the FTSE 350 index over the time period of 2000–2015, the authors find evidence of a significant and permanent stock price increase as a result of the initial debt announcement. The loan announcement results in a sustained increase in trading volume and liquidity. This improvement continues to persist once the authors control for stock price and trading volume effects in both the short and long run. Furthermore, the authors examine the spread decomposition around the same period, and discover the adverse selection of the bid–ask spread is significantly related to the initial bank loan announcement.

Research limitations/implications
The results can be attributed to the information cost/liquidity hypothesis, suggesting that investors demand a lower premium for trading stocks with more available information.

Originality/value
This is the first paper to look at multiple industries, more than one loan and information asymmetry effects.
Inflation and financial sector development in Sub-Saharan African countries
Authors: Kagochi John 
Published: September 2019

Purpose
The purpose of this paper is to examine the link between inflation and the financial sector performance in Sub-Saharan African (SSA) countries.

Design/methodology/approach
The study analyzes the relationship between inflation and the financial sector performance for selected 22 Sub-Saharan countries from 1980 to 2013. The study used panel data and the dynamic panel generalized method of moments econometric method. The study concentrates on the link between inflation and the development of the banking sector.

Findings
The findings suggest that inflation does not promote financial sector development in SSA region while trade openness has a positive impact on the selected financial development indicators. Other variables that enhance financial development in SSA include government expenditure and good governance.

Practical implications
The main policy implication of the study is that in order for SSA countries to benefit from a deeper and more active financial sectors, the rates of inflation must be maintained low and be consistently under control. Also, for SSA region financial sectors to become deeper and more active it is crucial to develop stronger economic institutions including independent central banks and sound fiscal authorities.

Originality/value
The study differs from previous studies as it includes more (22) countries from SSA region while previous studies were either regional or country specific. The study also incorporates trade openness and the role of institutional quality in enhancing financial development. This differentiates the study from previous studies on the subject from the region.
Changing contexts: from criminal to citizen
Authors: McKearney Aidan 
Published: September 2019

Purpose
The purpose of this paper is to provide a critical reflection on the profound changes regarding sexual minority rights in Britain and Ireland. It seeks to illustrate how recent legislative changes can impact the working lives of gay employees living and working in nonmetropolitan locales. The paper also aims to assess the role of LGBTQI movements, groups and networks, in facilitating voice and visibility and advancing equality.

Design/methodology/approach
Secondary research was undertaken to assist in contextualising the empirical findings, within a literature review. The paper presents findings derived from a qualitative study, involving in-depth interviews with 44 gay men in Britain and Ireland.

Findings
LGBTQI movements and groups have played a crucial role in facilitating voice, and visibility for LGBTQI people in both Britain and Ireland. These movements have themselves, undergone change, moving from liberationist-queer-radical approaches to normalising-sexual citizenship-radical approaches. Significant legislative advances have taken place in the 2000s, and these have had a positive impact on gay workers. However, there is a continuing need for organisations to respond in ever more strategic, effective and inclusive ways, if the promise of sexual citizenship is to be realised by gay people in the workplace. Local, self-organised LGBT groups can play an important role in building sexual citizenship in nonmetropolitan locales.

Originality/value
This paper’s value and contribution lie in its application of theoretical principles and models, most notably models of sexual citizenship, in a specific historical, geographical and spatial context. The paper offers an insight into the lives of gay men who reside and work in nonmetropolitan locales; and highlights the emergence of subtle forms of gay resistance and radicalism, through self-organised groups.
