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.

In recent times content reutilization in different media channels (such as in Cross Media Publishing or Windowing) is a much discussed concept in the media industry. It promises decreasing production and coordination costs by exploiting and leveraging synergy effects. First theoretical investigations emphasized the importance of efficient metadata-enriched linking and modularity techniques for a successful implementation of this multi-usage concept. However, nearly all recent approaches stop at the level of theoretical suggestions and do not include novel technological potentials provided by Semantic Web languages and tools. On the basis of previous works, this paper attempts to fill these research gaps by presenting a "proof of concept" implementation and by highlighting the possibilities and the potential of Semantic Web technologies in the context of media content reutilization.

Even though online communities enjoy a growing number of members, their success and popularity are regularly diminished by infringements of user trust. Consequently, community operators implement IT-based trust-promoting features to regain user trust. Not knowing if their efforts are effective, for community operators the question remains: how do trust-promoting IT-features contribute to user participation? In this paper, we present a content-analysis-based study that investigates the effect of trust-promoting IT-features. IT-features fall into four categories: usability, transparency, quality-assured content (QAC) and security/ privacy. The results show that usability, QAC, and security/ privacy strongly affect user participation. However, their implementation in online communities leaves a great deal of room for improvement. This work contributes to an understanding of trust-promoting IT-features and sheds some light on their efficiency. The findings have important implications for community operators, as we recommend that they invest in implementing usability, QAC, and security/ privacy IT-features to regain their users’ trust and increase user participation.
