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.

The introduction of smartphones and the accompanying profusion of mobile data services have had a profound effect on individuals’ lives One of the most influential service categories is location-based services (LBS) Based on insights from behavioural decision-making, a conceptual framework is developed to analyse individuals’ decisions to use LBS, focusing on the cognitive processes involved in the decision-making Our research is based on two studies First, we investigate the use of LBS through semi-structured interviews of smartphone users Second, we explore daily LBS use through a study based on diaries The findings highlight that the decision to use LBS can be described by either a comparative mode based on the value of LBS in relation to other available options, or an intuitive mode in which past experiences trigger the use of heuristics These modes in turn have positive influences on the continuance of LBS use and indicate changes in individuals’ information retrieval behaviours in everyday life In particular, the distinct value dimension of LBS in specific contexts of use changes individuals’ behaviours towards accessing location-related information

Changing information retrieval behaviours: an empirical investigation of users’ cognitive processes in the choice of location-based services

Despite its success in the software industry, Software-as-a-Service (SaaS) still struggles with fulfilling customer expectations regarding service quality. To contain customer churn rates to low levels, SaaS providers have to address their service quality weak spots and find out which factors are crucial for continued SaaS usage. Drawing on previous service quality literature, we develop a Zone-of-Tolerance (ZOT)-based SaaS-QUAL scale and validate it in a model of IS continuance based on two empirical surveys of SaaS using firms. By doing this, we examine the importance of SaaS service quality factors for shaping customer satisfaction and SaaS continuance intentions. Furthermore, we provide insights into what service factors effectively meet or miss SaaS customer expectations. As a practical contribution, we develop and apply a SaaS-QUAL scale that can be used as a diagnostic tool by SaaS providers and users alike. For researchers, we enrich existing research models on IS continuance by integrating a more fine-grained conceptualization of service quality confirmation that provides stronger explanatory power than in previous models.

Becoming Agile in the Digital Transformation: The Process of a Large-Scale Agile Transformation

Despite increasing acceptance of digital channels, total sales in the music business decreased by 31 % from 2004 to 2010. Music piracy is still considered one of the main causes for this. However, several studies found no effects or even positive effects of illegal downloading on record sales. In the past, piracy has been counteracted especially by prosecution and legal offers. Music as a Service (MaaS) represents a new, differing distribution approach in digital music. In contrast to the well-known music platforms for so-called a-la-carte downloads, such as the iTunes Store, MaaS possesses two important characteristics: transmission (streaming instead of downloading) and pricing model (flat rate instead of pay-per-download). Therefore, the consumption of music by means of purchasing and downloading is replaced by a monthly payment service (paid MaaS) and an ad-supported (free MaaS) service. First user surveys suggest that many music pirates are making use of these offers. To find out if MaaS is an attractive distribution channel for music pirates, we developed a model to explain the intention to use MaaS based on the Theory of Planned Behavior. To empirically test this model, we surveyed 132 music pirates. Among others, the outcome shows that the intention to use free MaaS is mainly affected by the attitude towards MaaS, while using paid MaaS is predominantly a result of the influence of users’ closest peers. The attitude towards MaaS is positively influenced by the desire to receive music recommendations, the payment type (in the form of a flat rate model), and the relative advantage of MaaS compared to illegal choices.
