IS quality aspects have been important in IS research and practice. In DeLone and McLean’s 2003 IS Success Model (ISM), the quality of information, system, and service are treated as independent determinants of user IS satisfaction and behavioral intention. Although numerous quality measures have been developed, most lack theoretical grounding and systematic content validation. Increasing use o...

The livestock industry and animal scientists have long recognized the importance of proper nutrition for cattle to achieve reproductive success. Timely resumption of estrus following parturition is a major milestone that a cow must reach for optimal reproduction. Dynamic interplay among all strata of the hypothalamo-hypophyseal-ovarian axis occurs during the cow’s transition from postpartum ane...

In species that live in one-male groups, resident males monopolize access to a group of females and are assumed to have higher reproductive success than bachelors. We tested this assumption using genetic, demographic, and behavioral data from 8 groups of wild blue monkeys observed over 10 years to quantify reproduction by residents and bachelors and compare the success of the two tactics. We us...

This paper contributes the discussion about applying DeLone & McLean success model. Since its introduction in 1992, the model has been widely used and evaluated. In this paper the model is used as a descriptive tool in evaluating a virtual learning environment. The study relies on prior research and does not question the measures. Instead, the model contributes the evaluation and describes the ...

Although the reproductive success of most organisms depends on factors acting at several spatial scales, little is known about how organisms are able to synthesize multi-scale information to optimize reproduction. Using longitudinal data from a long-lived seabird, Monteiro's storm-petrel, we show that average breeding success is strongly related to oceanic conditions at the population level, an...

Im Rahmen der Studie SUCCESS 2006 wurden (Miss-)Erfolgsfaktoren von Hardund Softwareentwicklungsprojekten in Deutschland identifiziert. Dieses Papier schildert die Motivation, die grundsätzlich angewandte Vorgehensweise, von der Erfolgsfaktorenidentifikation bis zur Hypothesenverifikation, sowie eine Zusammenfassung der Ergebnisse der Studie.

After more than two decades of development, e-Government services have become not only familiar to but also a significant part of citizens’ life. However, as the needs of citizens in using e-Government services changes, an improved understanding of citizen’s continuous use intention is warranted. This study therefore aims to explore the factors that influence citizens’ continuous use intention ...

Because of their role in mediating life-history trade-offs, hormones are expected to be strongly associated with components of fitness; however, few studies have examined how natural selection acts on hormonal variation in the wild. In a songbird, the dark-eyed junco (Junco hyemalis), field experiments have shown that exogenous testosterone alters individuals' resolution of the survival-reprodu...
