Positive Guidance is an approach to enhance the safety and operational efficiency of hazardous locations. This approach joins the highway engineering and human factors technologies to produce an information system matched to the characteristics of the location and the attributes of drivers. The Users' Guide to Positive Guidance is used to both analyze the location and develop the most effective solution. The Guide provides a procedure consisting of six major functions: Data collection at problem locations; problem specification; definition of driver performance factors; definition of information system requirements; determination of positive guidance information; and evaluation.

Abstract Benefit-cost analysis (BCA) is typically defined as an implementation of the potential Pareto criterion, which requires inclusion of any impact for which individuals have willingness to pay (WTP). This definition is incompatible with the exclusion of impacts such as rights and distributional concerns, for which individuals do have WTP. I propose a new definition: BCA should include only impacts for which consumer sovereignty should govern. This is because WTP implicitly preserves consumer sovereignty, and is thus only appropriate for ‘sovereignty-warranting’ impacts. I compare the high cost of including non-sovereignty-warranting impacts to the relatively low cost of excluding sovereignty-warranting impacts.

Background: With the evolution of data, via information into knowledge and beyond, intangible information assets (seen as an integral part of IT assets in this article) increasingly come to fore. A contemporary issue facing organisations in the knowledge economy and beyond is how best to safeguard and derive optimum value from their evolving information assets. A well-known fact is that risk exists because there is the possibility of threats to an asset. Likewise, no assets equals no risk. Although a large body of work is addressing threat models, the nature of the assets of the knowledge economy and beyond has not been well researched.Objectives: To investigate the definition of information assets across a number of financial, risk and information technology standards, frameworks and regulations, in order to ascertain whether a coherent definition exists across the board. If there is none (or limited), then propose a workable definition that is apt for the knowledge economy and beyond.Method: Qualitative thematic content analysis and a comparative study based on four main themes (Assets, Types of Asset, Information, and Information Assets). This then serves as a basis for argumentation schemes that lead to a proposed re-definition. The qualitative research approach assists us to address the concern of the incoherent definition of information and information assets across the board.Results: Contrary to expectations, the research study found the current definition to be incoherent. When the asset to be controlled is not properly defined and understood, it stands the risk of not being identified properly. This implies that the effectiveness, efficiency, reliability of internal control, and compliance with the applicable legislation and regulations would not be appropriate. This article highlights the need for a fundamental shift in how information assets (valuable, but unvalued organisational intangible assets) are being viewed and treated, especially with regard to information risk and internal controls.Conclusion: This article has identified a major defect in most standards, frameworks, and regulations dealing with regard to the safeguarding and management of information assets (and IT assets). It has established from the review carried out that information assets have not been properly defined across the board. Beyond this significant finding, it was further shown that the principle of risk (assessment) across the board requires the identification of the asset that needs to be controlled. A starting point, then, is a coherent definition (as proposed) for the information asset in itself. Therefore, proper definition across the board might assists in proper identification that could result in appropriate control and graceful handling of the end-of-life disposal.Keywords: infonomics; information asset; information risk; internal control; reputation loss

‘According to informational semantics, if it's necessary that a creature can't distinguish Xs from Ys, it follows that the creature can't have a concept that applies to Xs but not Ys.’ (Fodor, 1994, p. 32)There is, indeed, a form of informational semantics that has this verificationist implication. The original definition of information given in Dretske'sKnowledge and the Flow of Information(1981, hereafter KFI), when employed as a base for a theory of intentional representation or ‘content,’ has this implication. I will argue that, in fact, most of what an animal needs to know about its environment is not available as natural information of this kind. It is true, I believe, that there is one fundamental kind of perception that depends on this kind of natural information, but more sophisticated forms of inner representation do not. It is unclear, however, exactly what ‘natural information’ is supposed to mean, certainly in Fodor's, and even in Dretske's writing. In many places, Dretske seems to employ a softer notion than the one he originally defines. I will propose a softer view of natural information that is, I believe, at least hinted at by Dretske, and show that it does not have verificationist consequences. According to this soft informational semantics, a creature can perfectly well have a representation of Xs without being able to discriminate Xs from Ys.

Active introduction of digital technologies in all spheres of life is one of the main directions of state development as a whole and separate sphere of activity. The issue of using information technologies and systems during forensic examination is the subject of scientific research of many domestic and foreign scientists, but this sphere remains relevant. The introduction of digital technologies in forensic activities is one of the priority areas for the forensic science development at the present stage and has significant development potential. One of the areas of optimization and improvement of forensic activity is the development of methods to automate the formation of forensic experts and unify the description of the research process, identified features, justification and formulation of forensic conclusions, which requires legislative consolidation and regulation, analysis and definition of the subject area and development requirements and algorithms for the operation of the system interface. Unification and standardization of the content of forensic experts' opinions requires the development of common standards and an information system adopted by all subjects of forensic expertise, and meets the needs of practice. The development of an information system for forming an expert opinion and automatically forming an expert opinion will allow formalizing and unifying the description of research and results of forensic examinations, optimizing the time of forensic experts and potentially reducing the number of logical, typographical and technical errors, and simplifying quality control of forensic examinations. The proposed system will not only automate the technical work of registration of research results carried out during forensic examinations, but will also contain research algorithms, which will be stored in the form of data on already conducted research of similar objects (list and sequence of operations, identified features and their parameters).

La ausencia es un tópico común en los textos que toman a la desaparición forzada o al desaparecido como objeto de interés. No es extraño, pues se han conseguido a partir de ese concepto resultados poderosos. Sin embargo, como en casi todo lo que se naturaliza, el contenido del concepto y de sus declinaciones ha perdido fuelle y cuesta saber de qué se habla cuando se habla de ausencia. Dentro del esfuerzo por construir una definición rigurosa de “desaparición social”, este texto regresa sobre el concepto, observa sus usos más instalados y sobre todo busca vías para volver a llenarlo de contenido. En este texto daremos algunos pasos en esa renovación. Absence is a common topic in the literature that analyzes forced disappearances and the disappeared. This is understandable because approaches from this concept have brought about remarkable insights. However, as it usually happens when something is naturalized, the concept’s content and its derivations have lost centrality and we find it hard to tell what’s the meaning of this concept. In an endeavor to develop a rigorous definition of “social disappearance”, this article looks back at the concept, focuses on its dominant uses and, above all, searches for ways to fill it with content. The present work moves forward with the renovation of this notion.
