Efficiency of authoritative disclosure recommendations
Authors: Miihkinen Antti 
Published: November 2008

PurposeThis paper aims to explore the potential for disclosure recommendations given by authoritative supervisory bodies to reduce information asymmetry between the management and shareholders.Design/methodology/approachThere is only meagre existing evidence concerning firms' responses to disclosure recommendations. This paper uses descriptive statistics and OLS regression analysis to test if firms behave more similarly to voluntary or to mandatory disclosure when they follow the Committee of European Securities Regulators disclosure recommendation for International Financial Reporting Standards transition. Second, it analyses the determinants of and incentives for recommended transition disclosure.FindingsRecommended disclosure is documented to have more mandatory characteristics than purely voluntary disclosure. Moreover, the certain disclosure incentives for managers and corporate governance factors prove to have an impact on recommended disclosure. Firm size, growth prospects, and independent board members associate positively with recommended disclosure whereas there is a negative relationship between financial leverage and recommended disclosure.Research limitations/implicationsThe paper does not provide evidence on the cost differences between disclosure laws and authoritative disclosure recommendations. This could be examined by future research.Practical implicationsAuthoritative disclosure recommendations reduce information asymmetry. In some cases they may be a faster and more cost‐efficient way to achieve disclosure enhancements than regulation.Originality/valueThis paper is the first to explore the efficiency of authoritative disclosure recommendations in situations where urgent disclosure improvements are needed. The results have implications for regulatory bodies evaluating different strategies to reduce asymmetric information in these situations.

PurposeThe article's aim is to report and comment on the High Court case Spreadex Ltd v. Sekhon.Design/methodology/approachThe article outlines the facts surrounding the case and comments on the ruling.FindingsThe High Court rules that a customer who opted from private to intermediate customer status was contributorily negligent to his spread betting losses.Originality/valueThe article shows that there are many points in this decision where either what was revealed by the evidence or the Judge's comments and reasoning will echo beyond the parameters of the case itself.
Court of appeal confirms decision that claim in relation to pension transfer and drawdown advice is time barred
Authors: Gray Joanna 
Published: November 2008

PurposeThe article's aim is to report and comment on the Court of Appeal case Shore v. Sedgwick Financial Services Ltd & Others.Design/methodology/approachThe article outlines the facts surrounding the appeal and comments on the ruling.FindingsThe Court of Appeal reached the same conclusion as the trial Judge as to the outcome– both claims were time barred through limitation. However, the reasoning differed from that of the trial judge in certain respects as to the significance of the exact dates on which the claimant was properly to be seen to have suffered loss or to have been aware of his loss.Originality/valueThe article highlights how this case shows how important it is to actively and continually review one's financial situation in order to make any meaningful use of common law and statutory remedies for negligent or non‐compliant financial advice.
E‐business strategy in Western Europe: offshore BPO model perspective
Authors: Kim Gyeung‐Min 
Published: November 2008

PurposeThe purpose of this paper is first, to investigate the effective governance structure in early stage of offshore business process outsourcing (BPO), especially in the case where service provider's language is different from client's language, and second, to explore some of the conditions at the adoption of BPO that are likely to influence the shape of the governance structure.Design/methodology/approachGround theory building methodology that builds theory in a grounded and inductive fashion is used for this study. First, a genetic framework to analyze offshore BPO governance structure is derived from extant literature. Then, the framework is applied to an exploratory case analysis to explore an effective form of the governance mechanism.FindingsThe hybrid governance structure consists of inter‐organizational coordination mechanisms, inter‐organizational systems and social control. Companies that wish to offshore their business process should select the service providers that can facilitate setting up such hybrid governance structure.Originality/valueAs offshore BPO is expected to be booming in the next few years, this study helps both academics and practitioners to understand the effective governance structure of offshore BPO.
Managing outsourcing process: applying six sigma
Authors: Agarwal Rakesh , Bajaj Nonika 
Published: November 2008

PurposeThe decision to manage an outsourced project is easy but to provide client satisfaction is a difficult process. Outsourcing has been broadly accepted due to the extensive and useful business need they provide, even in those situations where the planning/decision support paradigm provided by the system poorly fits the business. The purpose of this paper is to propose an effective modeling methodology for managing the process of outsourced projects for the clients.Design/methodology/approachThe paper proposes a cimosa, O3ML and business outsourcing process using DMADV methodology ‐‐ an effective modeling methodology for managing the process of outsourced projects for clients.FindingsThe hybrid governance structure consists of inter‐organizational coordination mechanisms, inter‐organizational systems and social control. Companies that wish to offshore their business process should select the service providers that can facilitate setting up such hybrid governance structure.Research limitations/implicationsThe limitations of managing the outsourced paradigm (IT or business process), i.e. redesigning work and assigning responsibilities, need to be clearly recognized if they are to be dealt and delivered with in an effective manner.Practical implicationsSix sigma is a business process improvement strategy, which essentially checks that the performance of the business is according to the needs of the client. The end‐user of a product or service is a client and thus the deliverable of a project should be according to the needs of the client.Originality/valueThe paper is of value in proposing an effective modeling methodology for managing the process of outsourced projects for clients.
IS outsourcing – a strategic perspective
Authors: Foogooa Ravi 
Published: November 2008

PurposeThe purpose of this paper is to study the different facets of the strategic perspective of information systems (IS) outsourcing, compare strategic IS outsourcing with traditional IS outsourcing and identify research opportunities.Design/methodology/approachThis paper is based primarily on a review of the literature.FindingsIS outsourcing is now an accepted practice and the market is growing regularly. The initial hype surrounding IS outsourcing has died out and there is now a more rational approach towards outsourcing with an increasing emphasis for a strategic approach towards IS outsourcing rather than just a cost‐cutting motivation.Originality/valueThe paper clarifies the definitions of IS outsourcing and strategy, taking into consideration the evolution of the definitions before comparing strategic IS outsourcing with traditional IS outsourcing. The paper is concluded with identification of future research opportunities in the field of strategic IS outsourcing.
Public centric e‐governance in Jordan
Authors: Belwal Rakesh , Al‐Zoubi Khalid 
Published: November 2008

PurposeThe purpose of this paper is to assess the efforts made by Jordan in the direction of e‐governance and people's perception of corruption, trust, and e‐governance.Design/methodology/approachDesk research was conducted using secondary data sources followed by a field survey conducted with 412 sample respondents in three major cities of Jordan. Following the triangulation approach, the responses of university professors and the common people were also secured.FindingsThe Jordanian government's efforts towards e‐governance are commendable in the Middle East. However, there are certain impediments that are witnessed in the form of the digital divide, corruption, social bottlenecks, the stage of democratization, the lack of marketing to stakeholders, and the citizen's lack of adoption of technology. Educated people are aware of the merit of e‐governance contrary to the uneducated ones and perceive that corruption in the Jordanian public sector is increasing.Research limitations/implicationsThe study mainly reflects the views of the educated people. The views of the uneducated ones are secured through basic interactions as they expressed their inability to respond to the questionnaires. Somehow, the respondents are not very open to freely share their opinions or have abstained from participation‐since they consider this a sensitive issue within the Jordanian cultural and political setup. Further, asking opinions of members of the public might not be the ideal way of judging the level of corruption, or changes in it.Originality/valuePeople's perception is that Jordan is affected by a low level of corruption and that its citizens lack awareness of e‐governance. To remedy this, its citizens need to be motivated to trust and to participate in the process of e‐governance and to increase their understanding of the tools and technologies available.
A survey of ethics and regulation within the ICT industry in Australia: ethics education
Authors: Lucas Richard , Mason Nyree 
Published: November 2008

PurposeThe purpose of this paper is to present a preliminary analysis of age and gender across a number of questions asked in a survey of ethical attitudes of professionals in the information and communication technology (ICT) industry in Australia. While a large number of demographic questions regarding ethics and regulation, only those concerning age and gender are examined here.Design/methodology/approachAn online survey was conducted of the ICT workplace in Australia. The results were analyzed using SPSS.FindingsThere are some significant differences across the generations as well between the genders. Gen Y is different when compared to the others on how important ethical regulations ought to be. Gen Y thinks that ethical regulations ought to be less important. When gender was examined it was clear that males thought that ethical regulations ought to be significantly less important when compared with what females thought.Research limitations/implicationsWhile a larger sample size was desired, the consistency of the replies, when compared against a number of comparative populations, indicated that the replies we received were representative of the ICT workforce.Originality/valueThis paper raises many issues that demand greater care and attention be given when constructing new models of governing ethics within the Australian ICT workplace.
Incentive incompatibilities and arbitrage opportunities
Authors: Venezian Emilio 
Published: November 2008

PurposeThe paper aims to examine the practical importance of the finding of Mayers and Smith, that underinvestment is a problem when debt exposed to bankruptcy is part of the financial structure.Design/methodology/approachThe paper examines critically the assumptions underlying the Mayers and Smith paper.FindingsThe necessary assumption of deterministic arbitrage in the market for productive properties used by Mayers and Smith in their model is found to be unrealistic. Even if that assumption were valid, however, the result of Mayers and Smith establishes that raising exposed debt is a negative net present value project for the investor and hence that form of financing would not be found in practice.Practical implicationsThe existence of exposed debt does not explain the demand or commercial insurance.Originality/valueThe paper challenges the results of Mayers and Smith that have been used to examine the effect of debt on insurance demand for almost 20 years with mixed results.
Recapitalization, mergers, and acquisitions of the Nigerian insurance industry
Authors: Aduloju S.A. , Awoponle A.L. , Oke S.A. 
Published: November 2008

PurposeRecapitalization, mergers, and acquisitions are the most crucial issues confronting the Nigerian Insurance Industry (NII) in recent times. Yet information relating to these issues is rarely reported in print. The purpose of this paper is to present the results of a survey aimed at understanding the challenges faced within the NII and the reactions of the insurance underwriters towards the recapitalization exercise in Nigeria.Design/methodology/approachStratified sampling was applied in segregating listed insurance companies on the Nigeria Stock Exchange into top‐, middle‐, and lower‐management cadres. Random sampling was then used in selecting samples of the insurance company's staff. A questionnaire containing both open‐ended and closed‐form questions was used as the instrument to collect the primary data. Questionnaire administration was combined with personal interviews and record viewing in gathering relevant facts for use. Fifty‐four questionnaires were properly filled and returned from members of staff of the selected insurance companies. Chi‐square statistical procedures revealed the true position of the issues raised in the hypotheses.FindingsRecapitalization has been enhancing the development of the insurance industry and mergers and acquisitions have remained viable options for companies to remain in business.Research limitations/implicationsLimited financial and non‐financial resources, as well as a reluctance to release information by insurance companies and other operators in the industry, prevented further investigation.Originality/valueThe study serves as an information source for investors in the insurance industry.
Trading indicators with information‐gap uncertainty
Authors: Thompson Colin J. , Guttmann Anthony J. , Thompson Ben J.P. 
Published: November 2008

PurposeThis paper aims to provide a new quantitative methodology for predicting turning points and trends in financial markets time series based on information‐gap decision theory.Design/methodology/approachUncertainty in future returns from financial markets is modeled using information‐gap decision theory. The robustness function, which measures immunity to uncertainty, yields an additional time series whose turning points anticipate and reflect those of the underlying financial market time series.FindingsThe robustness function falling above or below certain thresholds is shown to provide a new reliable technical indicator for predicting highs and lows in financial markets. In addition, iterates of the robustness function are shown in certain cases to predict trends in financial markets.Research limitations/implicationsIn the analysis and application presented here the authors have only considered a special case of the robustness function. Stricter performance requirements and alternative process model estimates for future returns could be included in the information‐gap model formulation and analysis.Practical implicationsAn additional technical trading tool for applying Information‐Gap theory to financial markets has been provided.Originality/valueThis paper provides a new reliable methodology for constructing technical indicators for use by traders and fund managers in financial markets.
Jump liquidity risk and its impact on CVaR
Authors: Zheng Harry , Shen Yukun 
Published: November 2008

PurposeThe aim is to study jump liquidity risk and its impact on risk measures: value at risk (VaR) and conditional VaR (CVaR).Design/methodology/approachThe liquidity discount factor is modelled with mean revision jump diffusion processes and the liquidity risk is integrated in the framework of VaR and CVaR.FindingsThe standard VaR, CVaR, and the liquidity adjusted VaR can seriously underestimate the potential loss over a short holding period for rare jump liquidity events. A better risk measure is the liquidity adjusted CVaR which gives a more realistic loss estimation in the presence of the liquidity risk. An efficient Monte Carlo method is also suggested to find approximate VaR and CVaR of all percentiles with one set of samples from the loss distribution, which applies to portfolios of securities as well as single securities.Originality/valueThe paper offers plausible stochastic processes to model liquidity risk.
Estimation of VaR in conditional heteroscedastic models for principal‐protected notes
Authors: Chen Fen‐Ying 
Published: November 2008

PurposeThe aim of this paper is to examine the accuracy of GARCH and provide a comparison of GARCH‐type and the other time series models in financial commodity markets.Design/methodology/approachFirst, a model fitting is performed to choose suitable models with conditional volatility for principal‐protected and path‐dependent notes by means of Akaike information criterion (AIC) and Schwartz Bayesian information criterion (SBC). Second, this paper adopts the backtesting criteria and the Diebold and Mariano test to compare the performances of the selected time series models.FindingsThe empirical results show that the performance of GARCH is significantly worse than EGARCH(1,1) based on the Diebold and Mariano test criteria. By backtesting test criteria, the null hypothesis that a given confidence level is the true probability in ARCH(4) cannot be rejected. The interesting results are different from past studies.Originality/valueThere is little literature of principal‐protected notes that focuses on the downside risk for investors. But, managing downside risk is important for individual and institution investors. This paper offer new insight into the literature of principal‐protected notes.
Access control and privacy in web‐based social networks
Authors: Carminati Barbara , Ferrari Elena 
Published: November 2008

PurposeWeb‐based social networks (WBSNs) are today one of the most relevant phenomena related to the advent of Web 2.0. The purpose of this paper is to discuss main security and privacy requirements arising in WBSNs, with a particular focus on access control, and to survey the main research activities carried out in the field. The social networking paradigm is today used not only for recreational purposes; it is also used at the enterprise level as a means to facilitate knowledge sharing and information dissemination both at the internet and at the intranet level. As a result of the widespread use of WBSN services, millions of individuals can today easily share personal and confidential information with an incredible amount of (possible unknown) other users. Clearly, this huge amount of information and the ease with which it can be shared and disseminated pose serious security and privacy concerns.Design/methodology/approachThe paper discusses the main requirements related to access control and privacy enforcement in WBSNs. It presents the protection functionalities provided by today WBSNs and examines the main research proposals defined so far, in view of the identified requirements.FindingsThe area of access control and privacy for WBSNs is new and, therefore, many research issues still remain open. The paper provides an overview of some of these new issues.Originality/valueThe paper provides a useful discussion of the main security and privacy requirements arising in WBSNs, with a particular focus on access control. It also surveys the main research activities carried out in the field.
S2ProT: rank allocation by superpositioned propagation of topic relevance
Authors: Ågren Ola 
Published: November 2008

PurposeThe purpose of this paper is to assign topic‐specific ratings to web pages.Design/methodology/approachThe paper uses power iteration to assign topic‐specific rating values (calledrelevance) to web pages, creating a ranking or partial order among these pages for each topic. This approach depends on a set of pages that are initially assumed to be relevant for a specific topic; the spatial link structure of the web pages; and a net‐specific decay factor designatedξ.FindingsThe paper finds that this approach exhibits desirable properties such as fast convergence, stability and yields relevant answer sets. The first property will be shown using theoretical proofs, while the others are evaluated through stability experiments and assessments of real world data in comparison with already established algorithms.Research limitations/implicationsIn the assessment, all pages that a web spider was able to find in the Nordic countries were used. It is also important to note that entities that use domains outside the Nordic countries (e.g..com or.org) are not present in the paper's datasets even though they reside logically within one or more of the Nordic countries. This is quite a large dataset, but still small in comparison with the entire worldwide web. Moreover, the execution speed of some of the algorithms unfortunately prohibited the use of a large test dataset in the stability tests.Practical implicationsIt is not only possible, but also reasonable, to perform ranking of web pages without using Markov chain approaches. This means that the work of generating answer sets for complex questions could (at least in theory) be divided into smaller parts that are later summed up to give the final answer.Originality/valueThis paper contributes to the research on internet search engines.

Authors: Hammami Mohamed , Guermazi Radhouane , Ben Hamadou Abdelmajid 
Published: November 2008

PurposeThe growth of the web and the increasing number of documents electronically available has been paralleled by the emergence of harmful web pages content such as pornography, violence, racism, etc. This emergence involved the necessity of providing filtering systems designed to secure the internet access. Most of them process mainly the adult content and focus on blocking pornography, marginalizing violence. The purpose of this paper is to propose a violent web content detection and filtering system, which uses textual and structural content‐based analysis.Design/methodology/approachThe violent web content detection and filtering system uses textual and structural content‐based analysis based on a violent keyword dictionary. The paper focuses on the keyword dictionary preparation, and presents a comparative study of different data mining techniques to block violent content web pages.FindingsThe solution presented in this paper showed its effectiveness by scoring a 89 per cent classification accuracy rate on its test data set.Research limitations/implicationsMany future work directions can be considered. This paper analyzed only the web page, and an additional analysis of the visual content can be one of the directions of future work. Future research is underway to develop effective filtering tools for other types of harmful web pages, such as racist, etc.Originality/valueThe paper's major contributions are first, the study and comparison of several decision tree building algorithms to build a violent web classifier based on a textual and structural content‐based analysis for improving web filtering. Second, showing laborious dictionary building by finding automatically discriminative indicative keywords.
