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.

Thinking fast and slow.

Mittels Fallstudien wird in diesem Beitrag die verlagernde Wirkung von Business Intelligence auf eine unternehmensinterne Aufgabe, das Controlling, untersucht. Im Vordergrund der Betrachtung steht dabei die Allokationsveranderung controllingspezifischer Aufgaben zwischen verschiedenen Aufgabentragern im Unternehmen. Fur ein theorieorientiertes Vorgehen bieten Kompatibilitatskalkule dazu ein passendes Analysewerkzeug. Im Ergebnis zeigt sich, dass der Einsatz von Business Intelligence zu einer Delegation controllingspezifischer Aufgaben von der Controllingund der IT-Abteilung in die Fachabteilung fuhrt und insbesondere das interne Berichtwesen verlagert wird.

Age differences involving decision by description versus decision by experience were examined using the same general task structure to facilitate comparisons across decision types. Experiment 1 compared younger (19–43 years) and older (65–85 years) adults in four different experimental conditions involving a choice between a low-risk, low-return bet versus a high-risk, high-return bet. Experiment 2 compared young (18–27 years) to older (60–87 years) adults using similar experimental conditions, but with decisions involving a risky versus a certain option. Contrary to expectations, minimal differences were observed between ages in either study. Higher levels of ability and numeracy were associated with better performance and greater ability to benefit from experience, but the impact of these factors was not moderated by age. The results suggest that factors other than the simple distinction between decisions by description versus experience are necessary to characterize the nature of age effects in...

Use of descriptive and experiential information in decision making by young and older adults.

Many companies are using social sharing buttons to make it easier for consumers to refer a website or app to other potential consumers. Although these buttons are ubiquitous online, it remains unclear whether consumer referral propensity (i.e. the likelihood of consumers referring other consumers) varies across the channels through which consumers arrive at the website. In particular, we test whether referral propensity is higher for consumers themselves acquired through social referrals and compare them with consumers accessing the website through other commonly used channels, such as search engines and online advertisements. In addition, we examine whether the communication tool (i.e. social networking websites or instant messaging clients) through which the referral is transmitted affects consumers’ referral decisions. Our results indicate that consumers acquired through social referrals are more likely to make a referral and that the communication tools do not differ in their influence on consumers’ referral propensity.

Does the Source Matter? How Referral Channels and Personal Communication Tools Affect Consumers’ Referral Propensity

The success of open source software (OSS) projects heavily depends on sustained participation of project members. However, turnover of members and the ensuing instability have become very common. To better understand the turnover of members in OSS projects, we base our study on Herzbergs two-factor theory to investigate whether hygiene factors will lead to membersdissatisfaction. At the same time, we draw on Mobleys model of withdrawal decision process to hypothesize the relationship between dissatisfaction and perceived turnover. We develop a research model and present hypotheses that should be tested in the future. To empirically assess this model, we intend to survey OSS project members through the largest development platform Sourceforge. This study will provide a new insight into how the turnover of members emerges in OSS projects. The findings of this progressive research will have implications for both practice and theory.
