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.

Activity that places demands on cognitive resources has positive effects on cognitive health in old age. To further understand determinants of age-group differences in participation, we examined how negative aging stereotypes and responses associated with a cognitively challenging activity influenced future willingness to engage in that activity. Sixty-nine young (20-40 years) and 80 older (63-84 years) adults performed a letter-number sequencing (LNS) task at different levels of demand for 15 min, during which systolic blood pressure responses-a measure of effort mobilization-and subjective perceptions of task demands were assessed. Approximately half the participants were primed with a negative aging stereotype prior to this task. Following the LNS task, participants completed an effort-discounting task, with resulting subjective values indicating their willingness to perform the task at each level of demand. As expected, both subjective and objective indicators of cognitive demands as well as performance were associated with future willingness to engage in a difficult task, with these effects being significantly greater for older adults. In addition, although stereotype activation influenced older adults' engagement levels in the LNS task, it did not moderate willingness. Together, the results indicate that, relative to younger adults, older adults' decisions to engage in cognitively challenging activities are disproportionately affected by their subjective perceptions of demands. Interestingly, actual engagement with the task and associated success result in reduced perceptions of difficulty and greater willingness to engage. Thus, overcoming faulty and discouraging task perceptions may promote older adults' engagement in demanding but potentially beneficial activities.

Predictors of engagement in young and older adults: The role of specific activity experience.

Two stimuli can compet a company to redesign the way they are doing their business : business changes and new IT potentials. The,,classic methods do not deliver appropriate answers to the stimuli mentioned above. Many new methods have been developed under the global term Business Process Redesign. These methods differ from the classic methods in their design objects as well as in their components. The new methods give the companies important guidelines on how to design their processes today, unfortunately many questions are still open.

The implementation of functionalities inspired by ephemerality represents a new and promising direction for social media platform providers to ensure active user participation. Social media platforms that already rely on ephemerality show increased activity rates. However, ephemerality represents a whole new principle in the social media context; and its impact on user perceptions and behaviours has hardly been explored. Building on an exploratory research approach, we seek to develop an indepth understanding of how and why perceived ephemerality affects user behaviour. Based on 37 interviews with users of ephemerality-based platforms and drawing on a thematic analysis, we depict the promising nature of ephemerality by revealing its positive impact on user behaviour, such as an increase in users’ willingness to share information. We found that users’ control perceptions help to explain this positive relationship. However, and contrary to existing knowledge, we found that, in specific conditions, perceived ephemerality can negatively affect user behaviour. This adverse effect can be explained by users’ loss perceptions as an underlying cognitive mechanism. From a practical perspective, our findings highlight the need to keep the delicate balance of potential upsides and downsides of ephemerality when implementing functionalities.
