Firm and environmental influences on the mode and sequence of foreign research and development activities

This paper develops an explanation for the mode and sequence of entry that firms select for their international research and development activities. The hypotheses are based on the internalization and evolutionary theory perspectives. I first hypothesize that there is a sequence to the mode of foreign research and development activities initiated. I then discuss two firm capabilities and alternatives which might cause firms to omit parts of the sequence. The context of the study is the foreign research and development activities of incumbents and recent entrants to the Japanese pharmaceutical industry. The results indicate intriguing differences between the motivations of established firms and new entrants in establishing foreign research and development activities. © 1998 John Wiley & Sons, Ltd.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/34606/1/944_ftp.pd

Structure and Dynamics of Metalloproteins in Live Cells

X-ray absorption spectroscopy (XAS) has emerged as one of the premier tools for investigating the structure and dynamic properties of metals in cells and in metal containing biomolecules. Utilizing the high flux and broad energy range of X-rays supplied by synchrotron light sources, one can selectively excite core electronic transitions in each metal. Spectroscopic signals from these electronic transitions can be used to dissect the chemical architecture of metals in cells, in cellular components and in biomolecules at varying degrees of structural resolution. With the development of ever-brighter X-ray sources, X-ray methods have grown into applications that can be utilized to provide both a cellular image of relative distribution of metals throughout the cell as well as a high-resolution picture of the structure of the metal. As these techniques continue to grow in their capabilities and ease of use, so to does the demand for their application by chemists and biochemists interested in studying the structure and dynamics of metals in cells, in cellular organelles and in metalloproteins

Cause of Death Affects Racial Classification on Death Certificates

Recent research suggests racial classification is responsive to social stereotypes, but how this affects racial classification in national vital statistics is unknown. This study examines whether cause of death influences racial classification on death certificates. We analyze the racial classifications from a nationally representative sample of death certificates and subsequent interviews with the decedents' next of kin and find notable discrepancies between the two racial classifications by cause of death. Cirrhosis decedents are more likely to be recorded as American Indian on their death certificates, and homicide victims are more likely to be recorded as Black; these results remain net of controls for followback survey racial classification, indicating that the relationship we reveal is not simply a restatement of the fact that these causes of death are more prevalent among certain groups. Our findings suggest that seemingly non-racial characteristics, such as cause of death, affect how people are racially perceived by others and thus shape U.S. official statistics

Adoption complexity and economies of scope for new process technology in manufacturing

In a study of 39 domestic, durable goods plants, justifications for purchase of new process technology varied from the simple, single-goal approach to the complex, multiple-objective strategy. This variety contributes to a larger construct of adoption complexity, which was found to be a function of flexible manufacturing systems (FMS) (vs. cellular) purchase choice and plant size in a significant path model. Adoption complexity, in turn, significantly influences intrafirm personnel flows for implementation (e.g., mobility and job rotation). Flexible outcomes are not automatic with FMS purchase, however. Part family variety was significantly higher in larger plants and part variety was significantly promoted by personnel flows. Suggestions for further research and policy implications are discussed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/31648/1/0000582.pd

Grazing‐angle characterization of photosynthetic oxygen evolution protein monolayers

Variable‐period x‐ray standing wave (XSW) spectroscopy has been shown to be a practical probe for studying metalloproteins. The photosynthetic oxygen evolving complex (OEC) is a transmembrane multipolypeptide complex that catalyzes the oxidation of water to dioxygen. The OEC contains Mn, Ca, and Cl and is potentially amenable to study by XSW. In this feasibility study, preliminary results on OEC samples deposited on Au mirrors are discussed. First XSW measurements from the SSRL grazing‐incidence setup are presented. © 1996 American Institute of Physics.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/70867/2/RSINAK-67-9-3364-5.pd

NSLS X-19A beamline performance for X-ray absorption measurements

Characterization of the X-19 beamline at the National Synchrotron Light Source (NSLS) is described. The beamline is designed for high-resolution X-ray absorption spectroscopy over a wide energy range. All of the beamline optical components are compatible with ultrahigh vacuum (UHV) operation. This permits measurements to be made in a windowless mode, thereby facilitating lower energy (Z elements (e.g., S) in highly dilute systems. The future use of this beamline for carrying out various X-ray absorption experiments is presented.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/28566/1/0000368.pd
