Deposits of clastic carbonate-dominated (calciclastic) sedimentary slope systems in the rock record have been identified mostly as linearly-consistent carbonate apron deposits, even though most ancient clastic carbonate slope deposits fit the submarine fan systems better. Calciclastic submarine fans are consequently rarely described and are poorly understood. Subsequently, very little is known especially in mud-dominated calciclastic submarine fan systems. Presented in this study are a sedimentological core and petrographic characterisation of samples from eleven boreholes from the Lower Carboniferous of Bowland Basin (Northwest England) that reveals a >250 m thick calciturbidite complex deposited in a calciclastic submarine fan setting. Seven facies are recognised from core and thin section characterisation and are grouped into three carbonate turbidite sequences. They include: 1) Calciturbidites, comprising mostly of highto low-density, wavy-laminated bioclast-rich facies; 2) low-density densite mudstones which are characterised by planar laminated and unlaminated muddominated facies; and 3) Calcidebrites which are muddy or hyper-concentrated debrisflow deposits occurring as poorly-sorted, chaotic, mud-supported floatstones.

A theory is proposed to account for some of the age-related differences reported in measures of Type A or fluid cognition. The central hypothesis in the theory is that increased age in adulthood is associated with a decrease in the speed with which many processing operations can be executed and that this reduction in speed leads to impairments in cognitive functioning because of what are termed the limited time mechanism and the simultaneity mechanism. That is, cognitive performance is degraded when processing is slow because relevant operations cannot be successfully executed (limited time) and because the products of early processing may no longer be available when later processing is complete (simultaneity). Several types of evidence, such as the discovery of considerable shared age-related variance across various measures of speed and large attenuation of the age-related influences on cognitive measures after statistical control of measures of speed, are consistent with this theory.

The processing-speed theory of adult age differences in cognition.

In 1974 an article appeared in Science magazine with the dry-sounding title “Judgment Under Uncertainty: Heuristics and Biases” by a pair of psychologists who were not well known outside their discipline of decision theory. In it Amos Tversky and Daniel Kahneman introduced the world to Prospect Theory, which mapped out how humans actually behave when faced with decisions about gains and losses, in contrast to how economists assumed that people behave. Prospect Theory turned Economics on its head by demonstrating through a series of ingenious experiments that people are much more concerned with losses than they are with gains, and that framing a choice from one perspective or the other will result in decisions that are exactly the opposite of each other, even if the outcomes are monetarily the same. Prospect Theory led cognitive psychology in a new direction that began to uncover other human biases in thinking that are probably not learned but are part of our brain’s wiring.

Der Verkauf von Waren und Dienstleistungen und die Veroffentlichung von Inhalten wurden bislang als zwei verschiedene Geschaftsansatze im Internet betrachtet. Es ist jedoch zu beobachten, dass Medienunternehmen und Internethandler sich annahern. Auf der einen Seite haben Onlineshops erkannt, dass sich Inhalte fur die Kundengewinnung und -bindung eignen. Auf der anderen Seite versuchen Medienunternehmen nicht nur Aufmerksamkeit fur Angebote Dritter zu erzeugen und zu vermarkten, sondern selbst Verkaufe abzuwickeln. Dieser Beitrag analysiert die Konvergenz von Content und Commerce, gibt einen Uberblick uber die in diesem Zusammenhang relevanten Konzepte und verdeutlicht diese anhand von Praxisbeispielen. Daraufhin werden die Implikationen dieser Entwicklungen fur die beteiligten Akteure im Markt diskutiert.

The new performance measurement system Balanced Scorecard tries to overcome drawbacks of traditional financial measurement systems by focusing on a company’s individual strategies. These strategies derive from critical success factors. In the media sector, general critical success factors can be analysed, building a basis for deriving specific company strategies and measures. By analysing market forces and company resources, the factors Critical Mass, Customer Relations, Cooperations, Innovation, Leading Technologies, Competent Employees and Optimised Processes are found and -based on these factors - reasonable measures are elaborated. In combination with financial measures these build a generic model for individual Balanced Scorecards in the online media sector, helping companies to streamline the process of a Balanced Scorecard implementation.

Software reuse can lower costs and increase the flexibility of the software development process. Despite a large body of research focused on technical factors, there is still limited research on how companies reuse exiting components. In this study, we analyzed the reuse of external software components by taking a contingency approach. Using a survey of IT managers in the software industry, we empirically found that the use of external software components in an organization leads to better outcomes of the software development process. Among large companies, organic organizations adopt external reuse strategies more aggressively than mechanistic organizations. Architecture modularity is a significant driver of software reuse strategies. Finally, our findings suggest that some organizations may view external reuse as a longterm strategy that allows them to organize and deploy resources to achieve efficiency. External software reuse can thus be seen as an effective organization strategy to improve software project success.
