Abstract

Students’ assignments are often much better in style and organisation than the email messages they send to theirteachers. Some teachers, including myself, often ‘covertly’ correct students’ email messages for style, organisation,content, or correctness. While some students appreciate this extra effort from the teachers, others see it as an inhibitingintrusion. However, I have frequently noticed that students who are corrected repeatedly improve in writing emails. Myresearch concerns both the use of academic email writing and the correction of errors in student emails, and concludesthe following: students usually write only formal emails to their teachers; those instructors who correct email errors do notoffer explicit error correction; and if email writing were taught to the students, it would offer variety in the writing genresstudents currently compose

Abstract

Lectures can be digitally recorded and replayed to provide multimedia revision material for students who attended the class and a substitute learning experience for students unable to attend. Deaf and hard of hearing people can find it difficult to follow speech through hearing alone or to take notes while they are lip‐reading or watching a sign‐language interpreter. Notetakers can only summarise what is being said while qualified sign language interpreters with a good understanding of the relevant higher education subject content are in very scarce supply. Synchronising the speech with text captions can ensure deaf students are not disadvantaged and assist all learners to search for relevant specific parts of the multimedia recording by means of the synchronised text. Real time stenography transcription is not normally available in UK higher education because of the shortage of stenographers wishing to work in universities. Captions are time consuming and expensive to create by hand and while Automatic Speech Recognition can be used to provide real time captioning directly from lecturers’ speech in classrooms it has proved difficult to obtain accuracy comparable to stenography. This paper describes the development of a system that enables editors to correct errors in the captions as they are created by Automatic Speech Recognition.

This paper aims to propose a new highly efficient iterative method based on classical Oseen iteration for the natural convection equations.

Abstract

Purpose

This paper aims to propose a new highly efficient iterative method based on classical Oseen iteration for the natural convection equations.

Design/methodology/approach

First, the authors solve the problem by the Oseen iterative scheme based on finite element method, then use the error correction strategy to control the error arising.

Findings

The new iterative method not only retains the advantage of the Oseen scheme but also saves computational time and iterative step for solving the considered problem.

Originality/value

In this work, the authors introduce a new iterative method to solve the natural convection equations. The new algorithm consists of the Oseen scheme and the error correction which can control the errors from the iterative step arising for solving the nonlinear problem. Comparing with the classical iterative method, the new scheme requires less iterations and is also capable of solving the natural convection problem at higher Rayleigh number.

Abstract

A number of recent papers have raised serious questions about the validity of the German dominance hypothesis, using Granger (temporal) causality tests. If Germany dominates within the European Monetary System, then German monetary policy, measured by either money stocks or interest rates should Granger (temporally) cause other EMS countries’ monetary policies, but not vice versa. Empirical evidence leads analysts to conclude that the German dominance hypothesis is invalid, or at a minimum, in need of significant reformulation. Explores similar Granger causality tests, using the recent cointegration and errorcorrection modelling strategy, for the US and a group of developing countries during the Bretton Woods period, where conventional wisdom suggests that US policy dominated. Finds significant evidence of two‐way causality between the US money stock and the money stocks of a large number of developing countries. These findings raise a serious questions about the interpretation and/or appropriateness of the Granger causality test for investigating policy dominance hypotheses.

Abstract

Purpose

The purpose of this paper is to study the lead-lag relationship between the futures and spot foreign exchange (FX) market in India to understand the price discovery mechanism and the relationship between these two markets.

Design/methodology/approach

The estimation of lead-lag relationship is realized in three steps. First unit root and stationarity tests (Augmented Dickey-Fuller, Phillips-Perron, and Kwiatkowski-Phillips-Schmidt-Shin) are applied to check the stationarity of the data. Second, cointegration tests (Engle and Granger’s residual based approach and Johansen’s cointegration test) are applied to determine long run relationship between the markets. Third, error correction estimation is carried out by applying Vector Error Correction Model (VECM) to determine the leading market.

Findings

The study finds that there is a long run relationship between the futures and spot market where the futures market has emerged as the leading market for the four currencies studied in the paper.

Originality/value

Majorly, the studies on Indian FX market limit themselves to identifying the efficiency of the market and the studies which talk about the lead-lag relationship focus on the Indian stock market. This paper enhances the existing literature on Indian FX market by exploring the less explored subject of the lead-lag relationship between futures and spot FX market in India.

Abstract

This chapter aims to determine whether diversification benefits accrue from adding emerging market hedge funds (EMHFs) to an emerging market bond/equity portfolio, and subsequently whether the type of exposure hedge funds provide is justified by their fees. We use multivariate cointegration analysis to show that the advantages of adding hedge funds to balanced portfolios are limited for the three regions of Asia, Eastern Europe, and Latin America, as well as for the entire global emerging market universe. In summary, we find that emerging market hedge funds are generally redundant for diversifying long-only emerging market investment portfolios with long-term investment horizons. This result also holds when we extend our sample by the global financial crisis in 2008 and 2009 and allow for structural breaks according to the Gregory-Hansen (1996) test. Hence, even during the global financial crisis in 2008 and 2009, when risk diversification was most needed, long-term comovements between hedge funds and traditional assets is, with the exception of the Eastern European region, not disrupted. Because EMHF returns are heavily influenced by the emerging market equity and bond markets, we conclude that the “alpha fees” charged by EMHFs may not always be appropriate for the three main regions under consideration. This also holds, however, to a lesser extent, for a global diversification among hedge funds and traditional assets in emerging markets.

Abstract

Purpose

This study aims to investigate the dynamic relationships between oil price shocks and Indian stock market.

Design/methodology/approach

The study used daily data for the period starting from January 2001 to March 2013. In this study, Johansen's cointegration test, vector error correction model (VECM), Granger causality test, impulse response functions (IRFs) and variance decompositions (VDCs) test have been applied to exhibit the long-run and short-run relationship between them.

Findings

The cointegration result indicates the existence of long-term relationship. Further, the error correction term of VECM shows a long-run causality moves from Indian stock market to oil price but not the vice versa. The results of the Granger causality test under the VECM framework confirm that no short-run causality between the variables exists. The VDCs analysis revealed that the Indian stock markets and crude oil prices are strongly exogenous. Finally, from the IRFs, analysis revealed that a positive shock in oil price has a small but persistence and growing positive impact on Indian stock markets in short run.

Originality/value

The study would enhance the understandings of the interaction between oil price volatilities and emerging stock market performances. Further, the study would enable foreign investors who are interested in Indian stock market helps in understanding the conditional relationship between the variables.

Abstract

Accessibility design over the past several years has focused much of its attention on the development of a universal standard or a set of guidelines for delivering a diverse array of both content and instructional processes. Universal design for learning (UDL), for example, promotes providing multiple means of (a) representation, (b) action and expression, and (c) engagement for learners who have a wide range of disabilities as well as their typical peers. And while each instructional design element that represents a means of providing the differentiation required by the principle generally has a strong evidence-based support individually, it is difficult to assess any one of them within the larger ULD “multiple means” milieu of options. It is especially difficult to do this in regard to learners associated with any particular disability category. When it comes to targeted instruction, learner characteristics matter. It follows then that when it comes to developing an instructional design, that the learning characteristics of a targeted population be first and foremost considered as the point of departure in the design and development process. This chapter considers a wide range of instructional targets within the context of specific disability groups with a focus on learning goals, instructional design supports for those goals, and underlying cognitive processes that may help clarify the goals themselves as well as the instructional supports to achieve those goals.

Abstract

Many students in the United States struggle to achieve proficiency in writing. Writing is an important skill to develop, as it is a way for students to communicate what they know and integrate knowledge and critical thinking skills. A lack of writing proficiency can have a significant impact on academic performance in secondary school and on postsecondary outcomes. Improving writing instruction requires theoretically sound, scientifically validated teaching practices, including assessments and instructional methods. It also requires that teachers are well prepared to implement such practices, including using assessment data to tailor instructional methods to meet the needs of students who experience significant writing difficulties. The purpose of this chapter is to provide an overview of advances in research and practice related to validated teaching practices designed to improve the writing outcomes of students with intensive needs, and to describe an innovative way to prepare and support teachers to implement such practices.

Abstract

Purpose

Biometric authentication, which requires storage of biometric templates and/or encryption keys, raises a matter of serious concern, since the compromise of templates or keys necessarily compromises the information secured by those keys. To address such concerns, efforts based on dynamic key generation directly from the biometrics have recently emerged. However, previous methods often have quite unacceptable authentication performance and/or small key spaces and therefore are not viable in practice. The purpose of this paper is to propose a novel method which can reliably generate long keys while requires storage of neither biometric templates nor encryption keys.

Design/methodology/approach

This proposition is achieved by devising the use of fingerprint orientation fields for key generation. Additionally, the keys produced are not permanently linked to the orientation fields, hence, allowing them to be replaced in the event of key compromise.

Findings

The evaluation demonstrates that the proposed method for dynamic key generation can offer both good reliability and security in practice, and outperforms other related methods.

This is achieved by devising the use of fingerprint orientation fields for key generation.
