Research paper thumbnail of Three perspectives (panel session): if Markus' 1983 classic study, “power, politics, and MIS implementation,” were being reviewed today

Lynne Markus,“Power, Politics, and MIS Implementation,” is a classic in the study of information technology in organizations. The web version of the Social Science Citation Index shows that over 200 other published studies have cited Markus' classic since 1993 (the earliest year covered by the web version of the SSCI). Furthermore, its universal appeal is evident in its being regarded as an exemplar of not only positivist research (Lee 1989), but also interpretive research (Walsham 1993).

Science goals include characterization of the cosmic microwave background, measurement of the Sunyaev-Zel'dovich effect in galaxy clusters, and observations of forming galaxies. Cryogenic bolometers are the most sensitive broadband detectors in this frequency range. Because single bolometer pixels are reaching the photon noise limit for many observations, the development of large arrays will be critical for future science progress. Voltage-biased superconducting bolometers (VSBs) have several advantages compared to other cryogenic bolometers. Their strong negative electrothermal feedback enhances their linearity, speed, and stability. The large noise margin of the SQUID readout enables multiplexed readout schemes, which are necessary for developing large arrays. In this paper, we discuss the development of a large absorber-coupled array, a frequency-domain SQUID readout multiplexer,...

Grounded theory has been increasingly used and discussed in IS literature spanning the past decade. This development mirrors the establishment and wide adoption of qualitative research in information systems which has led to a diversity of approaches in qualitative analysis, among them grounded theory. The panel examines different applications of grounded theory in information systems, and addresses a number of issues that stem from the use of grounded theory in information systems research.

It will characterize the expected B-mode polarization due to gravitational lensing of the CMB, and search for the possible B-mode signature of inflationary gravitational waves. Its 250 mK focal plane detector array consists of 1,274 polarization-sensitive antenna-coupled bolometers, each with an associated lithographed band-defining filter. Each detector's planar antenna structure is coupled to the telescope's optical system through a contacting dielectric lenslet, an architecture unique in current CMB experiments. We present the initial characterization of this focal plane.

The experiment utilizes a unique focal plane of 1,274 antenna-coupled, polarization sensitive TES bolometers cooled to 250 milliKelvin. Employing this focal plane along with stringent control over systematic errors, polarbear has the sensitivity to detect the expected small scale B-mode signal due to gravitational lensing and search for the large scale B-mode signal from inflationary gravitational waves. polarbear was assembled for an engineering run in the Inyo Mountains of California in 2010 and was deployed in late 2011 to the Atacama Desert in Chile. An overview of the instrument is presented along with characterization results from observations in Chile.
