Examining the shareholder wealth effects of announcements of newly created CIO positions

Abstract: While information technology (IT) has been transforming the business landscape for a long time now, it is only recently that empirical evidence demonstrating the positive impact of IT on firm performance has begun to accumulate The strategic importance of a firm's IT capabilities is prompting an increasing number of companies to appoint chief information officers (CIOs) to effectively manage these assets Such moves are reflective of changes in top management thinking and policy regarding the role of IT and firms' approaches to IT governance This paper uses the event study methodology to examine market reactions to announcements of new CIO positions Findings strongly support the notion that, for firms competing in industries undergoing IT-driven transformation, announcements of newly created CIO positions do indeed provoke positive reactions from the marketplace

Adoptive transfer of immunity to Listeria monocytogenes. The influence of in vitro stimulation on lymphocyte subset requirements.

Abstract: BALB/c mice develop specific and relatively long lasting immunity after exposure to sublethal numbers of viable Listeria monocytogenes. This immunity can be passively transferred to naive recipients with maximal protection conferred by spleen cells obtained from donors 6 days after immunization. Immunity that can be directly transferred to syngeneic recipients is surprisingly short lived. Cell recipients lose immunity as early as 72 hr after transfer, and recipients express no detectable immunity after 1 wk. This short lived immunity requires both L3T4+ and Lyt-2+ T cell populations for full expression. Both the level of immunity transferred and the duration of the protective response expressed in recipients are dramatically increased if the spleen cell population is cultured in vitro with concanavalin A before cell transfer. Recipients of concanavalin A-activated cells express antigen-specific levels of immunity increased 100- to 1000-fold compared with syngeneic recipients of directly transferred immune spleen cells. In addition, this elevated level of adoptively transferred immunity remains constant for at least 8 wk. Transfer of this culture-enhanced immunity requires only an Lyt-2+ T cell population and is not influenced by cells of the L3T4+T cell subpopulation. Both direct as well as culture-enhanced transfer of immunity require major histocompatibility complex-compatible recipients. These findings suggest that two phenotypically distinct T cell subpopulations function in the development of the immune response to L. monocytogenes and that only one cell subpopulation is required for expression of immunity to this intracellular parasite.

From coworkers to friends: The development of peer friendships in the workplace

Abstract: This paper reports the results of our analysis of interviews with 38 individuals (representing 19 peer friendships) in which we explored factors and communication changes associated with the development of workplace friendships. We found that peer friendships experienced three primary transitions: from coworker/acquaintance‐to‐friend, friend‐to‐close friend, and close friend‐to‐almost best friend. The co‐worker‐to‐friend transition was perceived to be caused primarily by working together in close proximity, sharing common ground, and extra‐organizational socializing. Communication at this transition became broader, yet remained relatively superficial. The friend‐to‐close friend transition was associated primarily with problems in one's personal and work experiences. Communication at this transition became broader, more intimate, and less cautious. The close friend‐to‐almost best friend transition was associated primarily with life events, work‐related problems, and the passage of time. Communication becam...

Generation of 11-fs pulses from a self-mode-locked Ti:sapphire laser.

Abstract: By optimizing the intracavity dispersion compensation in a self-mode-locked Ti:sapphire laser, we have generated pulses of 10.95-fs duration. Dispersion within the laser cavity is reduced by use of a short 4.5-mm highly doped Ti:sapphire crystal and fused-silica prisms. The output from the laser has an average power of as much as 500 mW, with a wavelength centered at 780 nm and a bandwidth of 62 nm. Our results demonstrate that the exceptionally broad bandwidth of Ti:sapphire can be utilized to generate pulses that, to our knowledge, are shorter than has been possible with any other type of laser material to date.

Quantitative trait locus effects and environmental interaction in a sample of North American barley germ plasm.

Abstract: Quantitative trait locus (QTL) and QTL x environment (E) interaction effects for agronomic and malting quality traits were measured using a 123-point linkage map and multi-environment phenotype data from an F1-derived doubled haploid population of barley (Hordeum vulgare). The QTL × E interactions were due to differences in magnitude of QTL effects. Highly significant QTL effects were found for all traits at multiple sites in the genome. Yield QTL peaks and support intervals often coincided with plant height and lodging QTL peaks and support intervals. QTL were detected in the vicinity of a previously mapped Mendelian maturity locus and known function probes forα- andβ-amylase genes. The average map density (9.6 cM) should be adequate for molecular marker-assisted selection, particularly since there were few cases of alternative favorable alleles for different traits mapping to the same or adjacent intervals.
