Assimilation of Compliance Software in Highly Regulated Industries: An Empirical Multitheoretical Investigation

In this paper we follow a theory-based approach to study the assimilation of compliance software in highly regulated multinational enterprises. These relatively new software products support the automation of controls which are associated with mandatory compliance requirements. We use institutional and success factor theories to explain the assimilation of compliance software. A framework for analyzing the assimilation of Access Control Systems (ACS), a special type of compliance software, is developed and used to reflect the experiences obtained in four in-depth case studies. One result is that coercive, mimetic, and normative pressures significantly effect ACS assimilation. On the other hand, quality aspects have only a moderate impact at the beginning of the assimilation process, in later phases the impact may increase if performance and improvement objectives become more relevant. In addition, it turns out that position of the enterprises and compatibility heavily influence the assimilation process.

Differentiative requirements for human CD8$\sp+$ suppressor lymphocytes

The aim of this research was to characterize the differentiative requirements of human CD8$\sp{+}$ suppressor lymphocytes. We investigated the role of monocytes in cellular interactions required for generation of T suppressor cells (Ts) in pokeweed mitogen (PWM) stimulated peripheral blood mononuclear cells (PBMC). We observed that the functional activity of CD8$\sp{+}$ T cells was dependent on the concentration of monocytes in the inductive cultures; at concentrations normally present in peripheral blood, PWM stimulation induced potent suppressor activity, whereas under conditions of moderate monocyte depletion the same phenotypic subset of CD8$\sp{+}$ cells enhanced responses. We also demonstrated that differentiation of CD8$\sp{+}$CD28$\sp{-}$ suppressor cells could be mediated by soluble products elaborated by monocytes and CD4$\sp{+}$ cells, identified as PGE$\sb2$ and IFN$\gamma$ respectively. These two signals were required sequentially to cause Ts induction. That is PGE$\sb2$ was required initially, followed by an IFN$\gamma$-dependent differentiative step. We also explored the possibility that PGE$\sb2$ caused modulation of the IFN$\gamma$ receptor number and/or affinity on CD8$\sp{+}$ cells, which might render these cells responsive to the differentiative effect of the IFN$\gamma$-signal. Using radiolabelled $\sp{125}$I-IFN$\gamma$, direct binding assays demonstrated that 10$\sp{-8}$M PGE$\sb2$ selectively increased the number of receptors on the CD8$\sp{+}$ cells. In contrast CD4$\sp{+}$ cells treated similarly exhibited no significant change in their number of IFN$\gamma$ receptors. These results, thus, suggest a relationship between PGE$\sb2$ induced expression of IFN$\gamma$ receptor and the initial requirement for PGE$\sb2$ in IFN$\gamma$-dependent differentiation of Ts cells. Together, our results suggest a crucial role for PGE$\sb2$ and IFN$\gamma$ in regulation of the immune response. Furthermore, such detailed definition of the differentiative requirements for CD8$\sp{+}$ suppressor cells should provide new insight into fundamental mechanisms of immunoregulation. ^

Race and discourse analysis: Building a dialogue in health service research and health care settings

Using a framework for discourse analysis developed by Van Dijk, the investigator will pinpoint the pathological forms of discourse on race, defined as 'race talk' in three professional domains: health services research, public health provider organizations, and literature on multiculturalism. Attention will then turn to developing an analytical strategy for building more meaningful dialogue on race. The retrieval of potential resources for dialogue will be drawn from the third domain. Analysis will focus on enhancing the prospects of converting 'race talk' into dialogue. This will be accomplished by characterizing the normative preconditions as formal procedural requirements for dialogue and then supplementing these conditions with others related specifically to race. From here, the practical implications of combining procedural requirements and resources in each of the domains will be considered. Finally, the author will attempt to determine how these selected resources might be employed to transform 'race talk' in practice and lay the groundwork for a dialogue of understanding. ^

Establishing occupational and environmental health design requirements for Lunar and Mars settlements

In a study of Lunar and Mars settlement concepts, an analysis was made of fundamental design assumptions in five technical areas against a model list of occupational and environmental health concerns. The technical areas included the proposed science projects to be supported, habitat and construction issues, closed ecosystem issues, the "MMM" issues--mining, material-processing, and manufacturing, and the human elements of physiology, behavior and mission approach. Four major lessons were learned. First it is possible to relate public health concerns to complex technological development in a proactive design mode, which has the potential for long-term cost savings. Second, it became very apparent that prior to committing any nation or international group to spending the billions to start and complete a lunar settlement, over the next century, that a significantly different approach must be taken from those previously proposed, to solve the closed ecosystem and "MMM" problems. Third, it also appears that the health concerns and technology issues to be addressed for human exploration into space are fundamentally those to be solved for human habitation of the earth (as a closed ecosystem) in the 21st century. Finally, it is proposed that ecosystem design modeling must develop new tools, based on probabilistic models as a step up from closed circuit models. ^

Envisioning sustainable water futures in a transdisciplinary learning process: combining normative, explorative, and participatory scenario approaches

Competing water demands for household consumption as well as the production of food, energy, and other uses pose challenges for water supply and sustainable development in many parts of the world. Designing creative strategies and learning processes for sustainable water governance is thus of prime importance. While this need is uncontested, suitable approaches still have to be found. In this article we present and evaluate a conceptual approach to scenario building aimed at transdisciplinary learning for sustainable water governance. The approach combines normative, explorative, and participatory scenario elements. This combination allows for adequate consideration of stakeholders’ and scientists’ systems, target, and transformation knowledge. Application of the approach in the MontanAqua project in the Swiss Alps confirmed its high potential for co-producing new knowledge and establishing a meaningful and deliberative dialogue between all actors involved. The iterative and combined approach ensured that stakeholders’ knowledge was adequately captured, fed into scientific analysis, and brought back to stakeholders in several cycles, thereby facilitating learning and co-production of new knowledge relevant for both stakeholders and scientists. However, the approach also revealed a number of constraints, including the enormous flexibility required of stakeholders and scientists in order for them to truly engage in the co-production of new knowledge. Overall, the study showed that shifts from strategic to communicative action are possible in an environment of mutual trust. This ultimately depends on creating conditions of interaction that place scientists’ and stakeholders’ knowledge on an equal footing.

Das Schulhaus als geheimer Miterzieher. Normative Debatten in der Schweiz von 1830 bis 1930

Der Schulhausbau ist im 19. Jahrhundert einem starken Wandel unterworfen. In diesem Buch wird erstmals der Frage nachgegangen, wie und weshalb Normen für den Schulhausbau in der Schweiz von 1830 bis 1930 generiert und in formale Regelungen umgesetzt werden. Die Annahme, Erneuerungen im Schulhausbau betreffend Hygiene, Ergonomie, Ästhetik und Pädagogik hätten erst seit der Wende zum 20. Jahrhundert, insbesondere unter dem Einfluss der Reformpädagogik, stattgefunden, lässt das 19. Jahrhundert in Sachen Schulhausbau als rückständig erscheinen. Dabei wird vergessen, dass in dieser Zeit, gerade was die Zahl der gebauten Schulhäuser und die Entwicklung von Normen betrifft, eine intensive Arbeit geleistet wurde, die unter den historischen Umständen innovativ war. Die Organisation des Unterrichts, Licht und Luft im Schulzimmer und die Gesundheit der Schulkinder haben bereits das frühe 19. Jahrhundert normativ, praktisch und technisch beschäftigt. Gegen Ende des 19. Jahrhunderts findet eine über institutionelle und kantonale Grenzen hinausgehende öffentliche Diskussion statt, die breit rezipiert und professionalisiert wird. Verschiedene professionelle Akteure knüpfen an vorangegangene normative Debatten, staatliche Regulative, bestehende Traditionen und historische Kontexte an, um unterschiedlich motivierte, von Professionalisierungsprozessen beeinflusste Ansprüche an den Schulhausbau zu legitimieren, bis das Schulhaus zum „geheimen Miterzieher“ stilisiert wird.

A Normative Theory of Forgetting: Lessons from the Fruit Fly

Recent experiments revealed that the fruit fly Drosophila melanogaster has a dedicated mechanism for forgetting: blocking the G-protein Rac leads to slower and activating Rac to faster forgetting. This active form of forgetting lacks a satisfactory functional explanation. We investigated optimal decision making for an agent adapting to a stochastic environment where a stimulus may switch between being indicative of reward or punishment. Like Drosophila, an optimal agent shows forgetting with a rate that is linked to the time scale of changes in the environment. Moreover, to reduce the odds of missing future reward, an optimal agent may trade the risk of immediate pain for information gain and thus forget faster after aversive conditioning. A simple neuronal network reproduces these features. Our theory shows that forgetting in Drosophila appears as an optimal adaptive behavior in a changing environment. This is in line with the view that forgetting is adaptive rather than a consequence of limitations of the memory system.
