What does an archivist do?

By definition, an archivist is an individual responsible for appraising, acquiring, arranging, describing, preserving, and providing access to records of enduring value1. A record is a written or printed work of a legal or official nature that may be used as evidence or proof. It is data or information that has been fixed on some medium; that has content, context, and structure; and that is used as an extension of human memory or to demonstrate accountability. Records are often created or received in the course of individual or institutional activity and set aside (preserved) as evidence of that activity for future reference2

An adaptive approach for image organisation and retrieval

We propose and evaluate an adaptive approach towards content-based image retrieval (CBIR), which is based on the Ostensive Model of developing information needs. We use ostensive relevance to capture the user's current interest and tailor the retrieval accordingly. Our approach supports content-assisted browsing, by incorporating an adaptive query learning scheme based on implicit feedback from the user. Textual and colour features are employed to characterise images. Evidence from these features are combined using the Dempster-Shafer theory of evidence combination. Results from a user-centred, task-oriented evaluation show that the ostensive interface is preferred over a traditional interface with manual query facilities. Its strengths are considered to lie in its ability to adapt to the user's need, and its very intuitive and fluid way of operation

What (If Anything) Do Satisfaction Scores Tell Us about the Intertemporal Change in Living Conditions

This paper looks at the information content of satisfaction scores. It is argued that the information content depends on the extent to which people adapt to living conditions in general. Using data from the German Socio-Economic Panel Study (SOEP), the estimation of a dynamic panel data model provides evidence that adaptation takes place within a relatively short window of time: changes in living conditions are, for the most part, absorbed by an adjustment of the adaptation level within one year. This leads to the conclusion that the information content of satisfaction scores accentuates recent changes in living conditions. Remote changes are notcaptured by the according survey questions, even if these changes have long-term impact on living conditions. The usefulness of satisfaction scores as an indicator of people's living conditions is discussed.adaptation, dynamic panel data model, subjective well-being, satisfaction

Persuading developers to buy into software process improvement: an exploratory analysis

In order to investigate practitioners' opinions of software process and software process improvement, we have collected information from 13 companies, in a variety of ways i.e. the use of Repertory Grid Technique, survey and focus group discussions. Both the Repertory Grid Technique and the focus group discussions (43 discussions occurred, in total) produced a large volume of qualitative data. At the same time, other researchers have reported--investigations of practitioners, and we are interested in how their reports may relate to our own. Thus, other research publications can also be treated as a form of qualitative data. In this paper, we review advice on a method, content analysis, that is used to analyse qualitative data. Content analysis is a method for identifying and classifying words and phrases used in--ordinary language. We use content analysis to describe and analyse discussions on software--process and software process improvement. We report preliminary findings from an analysis--of both the focus group evidence and some publications. Our main finding is that there is an--apparent contradiction between developers saying that they want evidence for software process improvement, and what developers will accept as evidence. This presents a serious problem for research: even if researchers could demonstrate a strong, reliable relationship between software process improvement and improved organisational performance, there would still be the problem of convincing practitioners that the evidence applies to their particular situation

Information Leakage and Informed Trading Around Unscheduled Earnings Annoucnements

While there has been much judicial discussion regarding the competency of Australia’s continuous disclosure regime with reference to contemporaneous international standards, there has to date been limited empirical analysis of the Australian system’s effectiveness in preventing selective disclosure and information leakage. This paper presents an empirical study of information content and trading behaviour around unscheduled earnings announcements – comprising of profit upgrades, profit warnings and neutral trading statements – made by ASX-listed companies during 2004. The contention is that informed trading impacts on the stock returns and trading volumes of listed entities, and hence abnormal returns or trading volumes observed prior to an announcement provide evidence of information leakage. The paper models a range of factors that potentially influence firm disclosure practices and contribute to the level information asymmetry in the market during the pre-announcement period. Previous research has investigated the influence of firm size and information content in contributing to information leakage. This study further considers the variables of firm growth, capital structure and industry group.INFORMATION LEAKAGE, UNSCHEDULED ANNOUNCEMENTS, DOWNGRADES

Timely Industry Information as an Assurance Service: Evidence on the Information Content of the Book-to-Bill Ratio

Assurance services include independent professional services that improve the quality of information. Once such service is the collection of confidential information from participating firms on behalf of an industry association and the release of summarized information to investors. An example of this type of service is the collection of industry-wide information for the Semiconductor Industry Association. The primary output from this process is the monthly release of a ratio of new orders received to chips shipped, known as the book-to-bill ratio. We evaluate the association between book-to-bill disclosures and common stock prices. Statements in the financial press suggest that the book-to-bill index is an important indicator of future demand in the semiconductor industry. Because changes in the book-to-bill ratio signal impending changes in sales, the index may be relevant information for firm valuation. Our results suggest that investors in semiconductor firms utilize the book-to-bill ratio in revising their expectations of future cash flows. Specifically, we find (1) that eight of the 36 monthly book-to-bill announcements occurring during 1994 through 1996 produced share price reactions significant at the 10 percent level, and (2) that the price response across the subset of good news disclosures is positively related to the change in the book-to-bill ratio

Neural signals encoding shifts in beliefs

Dopamine is implicated in a diverse range of cognitive functions including cognitive flexibility, task switching, signalling novel or unexpected stimuli as well as advance information. There is also longstanding line of thought that links dopamine with belief formation and, crucially, aberrant belief formation in psychosis. Integrating these strands of evidence would suggest that dopamine plays a central role in belief updating and more specifically in encoding of meaningful information content in observations. The precise nature of this relationship has remained unclear. To directly address this question we developed a paradigm that allowed us to decompose two distinct types of information content, information-theoretic surprise that reflects the unexpectedness of an observation, and epistemic value that induces shifts in beliefs or, more formally, Bayesian surprise. Using functional magnetic-resonance imaging in humans we show that dopamine-rich midbrain regions encode shifts in beliefs whereas surprise is encoded in prefrontal regions, including the pre-supplementary motor area and dorsal cingulate cortex. By linking putative dopaminergic activity to belief updating these data provide a link to false belief formation that characterises hyperdopaminergic states associated with idiopathic and drug induced psychosis

The Economics of Open Source Hijacking and Declining Quality of Digital Information Resources: A Case for Copyleft

The economics of information goods suggest the need for institutional intervention to address the problem of revenue extraction from investments in resources characterized by high fixed costs of production and low marginal costs of reproduction and distribution. Solutions to the appropriation issue, such as copyright, are supposed to guarantee an incentive for innovative activities at the price of few vices marring their rationale. In the case of digital information resources, apart from conventional inefficiencies, copyright shows an extra vice since it might be used perversely as a tool to hijack and privatise collectively provided open source and open content knowledge assemblages. Whilst the impact of hijacking on open source software development may be uncertain or uneven, some risks are clear in the case of open content works. The paper presents some evidence of malicious effects of hijacking in the Internet search market by discussing the case of The Open Directory Project. Furthermore, it calls for a wider use of novel institutional remedies such as copyleft and Creative Commons licensing, built upon the paradigm of copyright customisation.Economics of information and knowledge, intellectual property rights, copyright, copyleft, public domain, open source, open content, hijacking, customisation, Creative Commons, DMOZ, search engine, directory.
