The Effect of Socializing via Computer-mediated Communication on the Relationship between Organizational Culture and Organizational Creativity
An organizationâs culture plays a strong role in its creating new knowledge, but, as organizations become more dispersed and technologies more advanced, many come to rely on computer-mediated communication (CMC) for employees to engage in all levels of knowledge management. Researchers have conducted little work to understand the effectiveness of socializing via CMC on organizational creativity, particularly as it relates to organizational culture. Some organizations tend toward a group culture, while others lean toward a rational culture. We investigate how both face-to-face (FTF) and computer-mediated socializing influence the relationship between organizational culture and organizational creativity at each cultural extreme. We surveyed 186 knowledge workers to investigate these relationships. Organizational culture interacted with socializing such that creativity in rational cultures benefited from using CMC to socialize, while group cultures appeared to be agnostic to different socializing types
A Brief History of the Midwest Association for Information Systems: 2005-2020
The Midwest Association for Information Systems (MWAIS), founded in 2005, was recognized as an outstanding chapter of the Association for Information Systems (AIS) for all five years of the award (2014, 2015, 2016, 2017, and 2018). MWAIS continues to grow and serve academics in the Midwest and the surrounding region through annual conferences, meetings and receptions at national and international conferences, and through its journal, Journal of the Midwest Association for Information Systems (JMWAIS). This article briefly describes the impetus and actors instrumental in the creation of the association and the current state of MWAIS, its conferences, and the journal
Inter-species variation in the oligomeric states of the higher plant Calvin cycle enzymes glyceraldehyde-3-phosphate dehydrogenase and phosphoribulokinase
In darkened leaves the Calvin cycle enzymes glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and phosphoribulokinase (PRK) form a regulatory multi-enzyme complex with the small chloroplast protein CP12. GAPDH also forms a high molecular weight regulatory mono-enzyme complex. Given that there are different reports as to the number and subunit composition of these complexes and that enzyme regulatory mechanisms are known to vary between species, it was reasoned that protein-protein interactions may also vary between species. Here, this variation is investigated. This study shows that two different tetramers of GAPDH (an A2B2 heterotetramer and an A4 homotetramer) have the capacity to form part of the PRK/GAPDH/CP12 complex. The role of the PRK/GAPDH/CP12 complex is not simply to regulate the 'non-regulatory' A4 GAPDH tetramer. This study also demonstrates that the abundance and nature of PRK/GAPDH/CP12 interactions are not equal in all species and that whilst NAD enhances complex formation in some species, this is not sufficient for complex formation in others. Furthermore, it is shown that the GAPDH mono-enzyme complex is more abundant as a 2(A2B2) complex, rather than the larger 4(A2B2) complex. This smaller complex is sensitive to cellular metabolites indicating that it is an important regulatory isoform of GAPDH. This comparative study has highlighted considerable heterogeneity in PRK and GAPDH protein interactions between closely related species and the possible underlying physiological basis for this is discussed. © 2011 The Author(s)
Non-Markovian quantum state diffusion for absorption spectra of molecular aggregates
In many molecular systems one encounters the situation where electronic
excitations couple to a quasi-continuum of phonon modes. That continuum may be
highly structured e.g. due to some weakly damped high frequency modes. To
handle such a situation, an approach combining the non-Markovian quantum state
diffusion (NMQSD) description of open quantum systems with an efficient but
abstract approximation was recently applied to calculate energy transfer and
absorption spectra of molecular aggregates [Roden, Eisfeld, Wolff, Strunz, PRL
103 (2009) 058301]. To explore the validity of the used approximation for such
complicated systems, in the present work we compare the calculated
(approximative) absorption spectra with exact results. These are obtained from
the method of pseudomodes, which we show to be capable of determining the exact
spectra for small aggregates and a few pseudomodes. It turns out that in the
cases considered, the results of the two approaches mostly agree quite well.
The advantages and disadvantages of the two approaches are discussed
