자연주의적 탐구조사(Naturalistic Inquiry)

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.

Die Ernuchterung nach dem E-Hype, die Krise der New Economy und die schwache Entwicklung der It-Budgets weltweit haben zu einem verstarkten Kostendruck sowie Kostenbewusstsein im It-Bereich der Unternehmen gefuhrt. Somit gewinnen Wirtschaftlichkeitsbetrachtungen der It im Unternehmen an Bedeutung: Das Ziel ist ein effektiver und effizienter Mitteleinsatz im It-Bereich. So hat etwa die Deutsche Bank ihre It durch einen Outsourcing-Vertrag mit Ibm im Umfang von ca. 2,5 Mrd Euro ausgelagert und beabsichtigt Kostenersparnisse von rund 1 Milliarde Euro uber einen Zeitraum von zehn Jahren zu realisieren und die Effizienz im It-Bereich zu erhohen (vgl.http://group.deutsche-bank.de/ir/deu 2003).

Anfang der 90er Jahre waren die Medienunternehmen erstmals massiv mit neuen Informations- und Kommunikationstechnologien konfrontiert. Schon bald wurde klar, das die nun bereitstehenden Online-Technologien erstmals Produkte und Dienstleistungen, Prozesse sowie ganze Wertschopfungsketten tangieren konnten.

The risks of sourcing software as a service — An empirical analysis of adopters and non-adopters

We examined young and older adults' use of descriptive information about risk (i.e., probability and expected value) in financial decision-making. In Experiment 1, participants chose between lotteries in pairs of bets that offered either two risky gains or one risky gain and one sure gain. Whereas they showed a strong and indiscriminate preference for high-probability gambles in risky-risky pairs, they selected sure options at high rates and risky options at low rates in risky-sure pairs, with slightly stronger effects in older relative to young adults due to age differences in ability. Experiment 2 involved the same task but in terms of losses. Participants, especially older adults, preferred low-probability gambles not accounted for by age differences in ability. Results suggest minimal consideration of expected value and a strong focus on probabilities in decision-making. They also suggest that cognitive ability and chronic goals differentially influence age effects depending on risk context.

Differential focus on probability and losses between young and older adults in risky decision-making

Most leading organizations, in all sectors of industry, commerce and government are dependent upon ERP for their organizational survival. Yet despite the importance of the decision to adopt ERP, IS research has so far neglected to comprehensively study the evaluation of ERP systems in general, and the impact of individual characteristics of IS managers on the ERP acquisition decision in particular. This study is the first of its kind to examine the impact of personality traits of IS managers on the relative importance they ascribe to evaluation criteria in ERP selection. We present the results which provide interesting insights into what evaluation criteria are more or less important for IS managers with different personality styles. In line with findings at the intersection of personality and IS research, we found that the personality dimensions of the five-factor model do considerably matter in ERP evaluation in the sense that the relative importance ascribed to evaluation criteria are affected by individual personality traits. Theoretical and practical implications are derived from our findings to advance insights for ERP adopters and vendors into the ERP evaluation process and to enhance the precision of IS theory.
