Nucleon Polarisabilities from Compton Scattering off the One- and Few-Nucleon System

These proceedings sketch how combining recent theoretical advances with data from the new generation of high-precision Compton scattering experiments on both the proton and few-nucleon systems offers fresh, detailed insight into the Physics of the nucleon polarisabilities. A multipole-analysis is presented to simplify their interpretation. Predictions from Chiral Effective Field Theory with special emphasis on the spin-polarisabilities can serve as guideline for doubly-polarised experiments below 300 MeV. The strong energy-dependence of the scalar magnetic dipole-polarisability $\beta_{M1}$ turns out to be crucial to understand the proton and deuteron data. Finally, a high-accuracy determination of the proton and neutron polarisabilities shows that they are identical within error-bars.

Intensification, Storage, and the Use of Alpine Habitats in the Central Great Basin: Prehistoric Subsistence Strategies in the Toquima and Toiyabe Ranges

Alpine villages are extremely rare in the Great Basin. To date, villages located at elevations above 10,000 ft. are only known to occur in the White Mountains and the Toquima Range. Demographic forcing has been used to explain the existence of these villages, but this proposition does not identify the selective pressures that led to the establishment of high-elevation villages in some ranges but not others. Comparison of artifact distributions and environmental structure in the Toquima Range, where a village exists, and the Toiyabe Range, where one does not, is consistent with the hypothesis that alpine villages were subsidized by intensive exploitation of mid-elevation pinyon groves associated with low-cost travel corridors, which facilitated transport of pine nuts to upland village locations. This study also reveals that limber pine may have played a role in alpine village subsistence, and identifies the need for further research on the value of this resource

Some Influences of Greek and Roman Rhetoric on Early Letter Writing1

Letter writing, known as dictamen in the Medieval and Renaissance periods, was formatively dependent upon the theory of oral rhetoric of the ancient world, some reflections of which are still apparent today. Three oral rhetoric precepts were applied by letter writers: inventio, locating material for three kinds of letters; dispositio, organizing letters into an introduction, body, and conclusion; and style, applying ornateness along with clarity and correctness to prose. Representative English, Italian, and German letter writing practi tioners carried the oral tradition along.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68843/2/10.1177_002194368802500302.pd

Cultural Communication Problems of Foreign Business Personnel in the United States

This paper discusses the communication problems of the German expatriate em ployee in the United States, and notes some differences in oral and written means of communication as seen by the expatriate. Interviews with both Germans and Ameri cans, in Germany and the United States, lead to the conclusion that technical com petence outweighs cultural awareness; that Americans are often unaware of cultural differences between themselves and foreign employees; that language incompetence is more an American problem; and that cultural variances do affect oral and written modes of communication.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68387/2/10.1177_002194367501300102.pd

Business Communication Consulting and Research in Multinational Companies

Communication research knows no geographic boundaries. Yet, when an American wishes to do communication research or consulting in a foreign country there arise a series of issues that can impede solid investigation. To understand some of the issues along with suggestions on meeting those issues is the purpose of the following article.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68517/2/10.1177_002194367801500303.pd

Business Communication in the People's Republic of China

This is a seminal statement on the pre-eminent position held by business communication in China's largest business school—specializing in interna tional trade—the Beijing Institute of Foreign Trade. The authors provide some historical background, review three courses in business communica tion in China, summarize the method of instruction, and end with con cludions and opportunities for closer academic ties with China in making business communication a truly international discipline.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68578/2/10.1177_002194368302000103.pd

Impact of tumor-specific targeting on the biodistribution and efficacy of siRNA nanoparticles measured by multimodality in vivo imaging

Targeted delivery represents a promising approach for the development of safer and more effective therapeutics for oncology applications. Although macromolecules accumulate nonspecifically in tumors through the enhanced permeability and retention (EPR) effect, previous studies using nanoparticles to deliver chemotherapeutics or siRNA demonstrated that attachment of cell-specific targeting ligands to the surface of nanoparticles leads to enhanced potency relative to nontargeted formulations. Here, we use positron emission tomography (PET) and bioluminescent imaging to quantify the in vivo biodistribution and function of nanoparticles formed with cyclodextrin-containing polycations and siRNA. Conjugation of 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid to the 5' end of the siRNA molecules allows labeling with 64Cu for PET imaging. Bioluminescent imaging of mice bearing luciferase-expressing Neuro2A s.c. tumors before and after PET imaging enables correlation of functional efficacy with biodistribution data. Although both nontargeted and transferrin-targeted siRNA nanoparticles exhibit similar biodistribution and tumor localization by PET, transferrin-targeted siRNA nanoparticles reduce tumor luciferase activity by {approx}50% relative to nontargeted siRNA nanoparticles 1 d after injection. Compartmental modeling is used to show that the primary advantage of targeted nanoparticles is associated with processes involved in cellular uptake in tumor cells rather than overall tumor localization. Optimization of internalization may therefore be key for the development of effective nanoparticle-based targeted therapeutics
