Purpose Digital curation addresses the technical, administrative and financial ecology required to ensure that digital information remains accessible and usable over the long term. The purpose of this paper is to trace digital curation’s disciplinary emergence and examine its position within the information sciences domain in terms of theoretical principles, using a case study of developments in the UK and the USA. Design/methodology/approach Theoretical principles regarding disciplinary development and the identity of information science as a discipline are applied to a case study of the development of digital curation in the UK and the USA to identify the maturity of digital curation and its position in the information science gamut. Findings Digital curation is identified as a mature discipline which is a sub-meta-discipline of information science. As such digital curation has reach across all disciplines and sub-disciplines of information science and has the potential to become the overarching paradigm. Practical implications These findings could influence digital curation’s development from applied discipline to profession within both its educational and professional domains. Originality/value The disciplinary development of digital curation within dominant theoretical models has not hitherto been articulated.

Purpose – The purpose of this paper is to explore the challenges of measuring fraud in overseas aid. Design/methodology/approach – The research is based on 21 semi-structured interviews with key persons working in the delivery of aid in both the public and voluntary sectors. It uses the UK Department for International Development as a case study to applying more accurate measures of fraud. Findings – This paper shows there are significant challenges to using fraud loss measurement to gauge fraud in overseas aid. However, it argues that, along with other types of measures, it could be used in areas of expenditure in overseas governments and charities to measure aid. Given the high risk of such aid to fraud, it argues helping to develop capacity to reduce aid, of which measuring the size of the problem is an important part; this could be considered as aid in its own right. Research limitations/implications – The researchers were not able to visit high-risk countries for fraud to examine in the local context views on the challenges of measuring fraud. Practical implications – The paper offers insights on the challenges to accurately measuring fraud in an overseas context, which will be useful to policy-makers in this context. Social implications – Given the importance of as much aid as possible reaching recipients, it offers an important contribution to helping to reduce losses in this important area. Originality/value – There has been very little consideration of how to measure fraud in the overseas aid context, with most effort aimed at corruption, which poses some of the same challenges, as well as some very different challenges.

Purpose This study aims to investigate the extent and characteristics of corporate internet disclosure via companies’ websites as well via social media and networks sites in the four leading English-speaking stock markets, namely, Australia, Canada, the UK and the USA. Design/methodology/approach A disclosure index comprising a set of items that encompasses two facets of online disclosure, namely, company websites and social media sites, is used. This paper adopts a data science approach to investigate corporate internet disclosure practices among top listed firms in Australia, Canada, the UK and the USA. Findings The results reveal the underlying relations between the determining factors of corporate disclosure, i.e. profitability, leverage, liquidity and firm size. Profitability in its own has no great effect on the degree of corporate internet disclosure whether via company websites or social media sites. Liquidity has an impact on the degree of disclosure. Firm size and leverage appear to be the most important factors driving better disclosure via social media. American companies tend to be on the cutting edge of technology when it comes to corporate disclosure. Practical implications This paper provides new insights into corporate internet disclosure that will benefit all stakeholders with an interest in corporate reporting. Social media is an influential means of communication that can enable corporate office to get instant feedback enhancing their decision-making process. Originality/value To the best of the authors’ knowledge, this study is amongst few studies of corporate disclosure via social media platforms. This study has adopted disclosure index incorporating social media as well as applying data science approach in disclosure in an attempt to unfold how accounting could benefit from data science techniques.

Purpose – This paper aims to present a holistic framework, termed ShaRInK (Sharer, Relations, Institution, Knowledge), that depicts key categories of influences that shape individual perceptions of knowledge sharing within an organisational setting. Design/methodology/approach – An exploratory and qualitative case study strategy in which empirical data were gathered from 24 interviewees that were based in four different branches (i.e. China, The Netherlands, the UK and the USA) of a single information technology services organisation. Findings – The findings led to a holistic framework that depicts four key categories of influences that shape knowledge sharing from an individual perspective: attitudes and characteristics of the sharers, relations between the sharers, institutions which act as a united entity on sharer perceptions and knowledge itself. Furthermore, the four key influences not only shape knowledge sharing independently but are intertwined and have a synergistic effect. The ShaRInK framework is formed by combining these. Originality/value – The findings indicate that knowledge sharing from an individual-level perspective is a more complex phenomenon than currently portrayed in the literature. All four key influences, each being fundamentally different in nature, and their relationships should be taken into account. Equally, the ShaRInK framework can be applied by organisations when developing a knowledge-sharing strategy or auditing existing strategies.

Purpose The tenuous financial viability of many of Georgia’s rural hospitals has driven increased scrutiny of the hospital authorities (HAs) that own and govern them. HAs are a type of “special district” established in state law to allow for specialization of function, while evading statutes that can limit local government borrowing and multi-year contracts. The paper aims to discuss this issue. Design/methodology/approach This paper uses a case example to introduce transparency and accountability in one local Georgia hospital and expands to include a descriptive analysis of transparency measures in 29 rural Georgia HAs. Findings Findings indicate that, like many other special districts in Georgia and the USA, Georgia’s rural HAs often act more like private entities than the public organizations they are. The lack of transparency demonstrated in this sector limits access to public information and reduces opportunities for citizen engagement, a necessary component of representative institutions. Research limitations/implications This case study is limited to Georgia HAs; however, the data support the lack of accountability and transparency found in many special district governments. Originality/value The lack of transparency in all of the organizations reviewed in this study demonstrates blurred lines between between public matters and private interests and raises questions of transparency, a key value in democracies.

Do professional sport franchise owners overpromise and underdeliver the public? Lessons from Brooklyn’s Barclays Center

Purpose The purpose of this paper is to evaluate a number of promises typically made by owners of professional sports franchises in the USA that are also typically ignored or underevaluated by public bureaus and their elected principals using the Barclays Center in Brooklyn, New York as a case study. Ex post subsidy outcomes are evaluated against ex ante subsidy promises in order to draw lessons that can inform and improve subsidy debates elsewhere. Design/methodology/approach The case study adopts a pre-post strategy drawing on data from multiple sources over a period of up to ten years in order to triangulate the narrative and build credibility. The franchise owner’s ex ante promises and financial projections were obtained from various media including newspaper, video and interviews between December 2003, when the arena was publicly announced, and September 2012, when the arena opened. Data on ex post outputs were obtained from financial documents and government records covering periods from September 2011 through June 2016. Findings The franchise owner is found to have exaggerated the arena’s financial condition, under-delivered on its employment promises, and exaggerated the scope and timeliness of ancillary real estate development. Only promises of event frequency and attendance levels, measures of the public’s demand for the facility, have been met during the first three years. Research limitations/implications Because the evaluation is a case study, causal conclusions cannot be drawn and some aspects of the Barclays Center context may not be applicable in other jurisdictions or subsidy debates. In addition, the case study does not evaluate an exhaustive list of the promises franchise owners make. Practical implications Franchise owners have a financial incentive to overpromise public benefits, since subsidy levels are tied to what the public is perceived to receive in return. This case study demonstrates that the public sector should not take owners’ promises and projections of public benefits at face value. Moreover, the case study reveals that the public sector should put more effort into ensuring ex post policy and data transparency in order to facilitate benefit-cost analyses of such subsidies. Originality/value The data required to evaluate promises, other than economic development ones, made by franchise owners are not systematically collected across state and local governments in the USA, making large-n studies impossible. Case studies are underutilized approaches in this area of public affairs, and this paper illustrates their usefulness. By focusing on a single facility, an evaluation of the franchise owner’s less acknowledged and arguably more important promises about the facility and its local impact is possible.

Purpose This paper aims to critically analyse the existing framework on assets tracing and recovery in Nigeria. It will thereafter provide analysis of the asset and recovery measures of advanced countries such as the USA and the UK. The results from the analysis will yield maximum insight and help the Nigerian Government to make better policies and laws on assets tracing and recovery. Design/methodology/approach This paper will rely on primary and secondary data drawn from the public domain. It will also rely on documentary research. Findings This paper determined that the Nigeria asset recovery scheme is likely to be more effective if Nigeria adopts the approach of the UK and the USA. Research limitations/implications This paper will suggest new ways for assets tracing and recovery. The suggested approaches/methods are being used in advanced countries such as the UK and the USA. Originality/value Previous research papers have extensively discussed the problems faced with assets tracing and recovery from a prohibitive and investigative standpoint. This paper will discuss the topic from a preventive standpoint with little focus on investigative mechanisms.

PurposeUsing data from 1820 onwards in a group of seven countries, namely, Australia, Chile, Denmark, France, the UK, Italy and the USA, the authors investigate if there is a long-run equilibrium relationship between the two variables (GDP and population).Design/methodology/approachUsing fractional integration and cointegration methods, this paper deals with the analysis of the relationship between GDP and population using historical data.FindingsThe authors’ results show first that the two series are highly persistent, presenting orders of integration close to or above 1 in practically all cases. Testing cointegration between the two variables, the results are quite variable depending on the methodology and the bandwidth numbers used, but if cointegration takes places, it only occurs in the cases of France, Italy and the UK.Research limitations/implicationsThe fact that the orders of integration of all series is close to 1 indicate high levels of persistence with shocks having permanent effects and requiring strong measures to recover the original trends.Practical implicationsAny shock affecting the series will have a permanent nature, persisting forever.Originality/valueUpdated time series techniques based on concepts such as fractional integration and cointegration are used.
