THE COMPLEMENTARY EFFECTS OF EMPATHY AND NONVERBAL COMMUNICATION TRAINING ON PERSUASION CAPABILITIES
This paper investigates the possible complementary effects that training in empathy and nonverbal communication may have on persuasion capabilities. The narrative considers implications from the literature and describes an exploratory study in which students, in a managerial setting, were trained in empathy and nonverbal communication. Subsequent evaluations of these students by faculty evaluators and the students themselves provide preliminary evidence that training in empathy, on the one hand, and nonverbal communication on the other can be effective, but concurrent training in both of these is superior to concentration in only one. This is the first research report which deals with such concurrent training and its impact on persuasion effectiveness in business communication
An Analysis of Small Business Hiring of Seniors
This study investigated small business hiring of senior citizens. It found that older persons make up a moderate percentage of the small business work force. The respondents reported dependability, possession of the work ethic, respect for authority, experience, and company loyalty as advantages of seniors. The major disadvantages were physical limitations, illness, slow work, and costs of medical benefits. Most respondents plan to hire larger numbers of seniors in future periods
Market Orientation and its Measurement in Universities
Historically, the measurement of market orientation has proved to be difficult, due to the low external validity of the concept. Existing scales exhibit acceptable properties in measuring market orientation in business organizations, but are less accurate in the context of higher education institutions. This paper compares the performance of three scales – the MARKOR scale, the MKTOR scale, and the University MARKOR scale – in the context of academic organizations. Results indicate that the MARKOR and the MKTOR scales need modifications, in order to accurately measure the construct in the new context. Evidence suggests that the student-oriented University MARKOR scale outperforms existing scales in predicting university performance
Mass-Losing Semiregular Variable Stars in Baade's Windows
By cross-correlating the results of two recent large-scale surveys, the
general properties of a well defined sample of semi-regular variable stars have
been determined. ISOGAL mid-infrared photometry and MACHO lightcurves are
assembled for approximately 300 stars in the Baade's Windows of low extinction
towards the Galactic bulge. These stars are mainly giants of late M spectral
type, evolving along the asymptotic giant branch (AGB). They are found to
possess a wide and continuous distribution of pulsation periods and to obey an
approximate log~period -- bolometric magnitude relation or set of such
relations.
Approximate mass-loss rates in the range of 1e-8 to 5e-7 M_sun per year are
derived from ISOGAL mid-infrared photometry and models of stellar spectra
adjusted for the presence of optically-thin circumstellar silicate dust.
Mass-loss rates depend on luminosity and pulsation period. Some stars lose mass
as rapidly as short-period Miras but do not show Mira-like amplitudes. A period
of 70 days or longer is a necessary but not a sufficient condition for mass
loss to occur.
For AGB stars in the mass-loss ranges that we observe, the functional
dependence of mass-loss rate on temperature and luminosity is found to be in
agreement with recent theoretical predictions. If we include our mass-loss
rates with a sample of extreme mass-losing AGB stars in the Large Magellanic
Cloud, we get the general result for AGB stars that mass-loss rate is
proportional to luminosity^{2.7}, valid for AGB stars with 10^{-8} to 10^{-4}
M_sun per year (Abridged).Comment: to appear in The Astrophysical Journal, 51 pages, 9 figures, 3

Structure and Functions of Pediatric Aerodigestive Programs: A Consensus Statement
Aerodigestive programs provide coordinated interdisciplinary care to pediatric patients with complex congenital or acquired conditions affecting breathing, swallowing, and growth. Although there has been a proliferation of programs, as well as national meetings, interest groups and early research activity, there is, as of yet, no consensus definition of an aerodigestive patient, standardized structure, and functions of an aerodigestive program or a blueprint for research prioritization. The Delphi method was used by a multidisciplinary and multi-institutional panel of aerodigestive providers to obtain consensus on 4 broad content areas related to aerodigestive care: (1) definition of an aerodigestive patient, (2) essential construct and functions of an aerodigestive program, (3) identification of aerodigestive research priorities, and (4) evaluation and recognition of aerodigestive programs and future directions. After 3 iterations of survey, consensus was obtained by either a supermajority of 75% or stability in median ranking on 33 of 36 items. This included a standard definition of an aerodigestive patient, level of participation of specific pediatric disciplines in a program, essential components of the care cycle and functions of the program, feeding and swallowing assessment and therapy, procedural scope and volume, research priorities and outcome measures, certification, coding, and funding. We propose the first consensus definition of the aerodigestive care model with specific recommendations regarding associated personnel, infrastructure, research, and outcome measures. We hope that this may provide an initial framework to further standardize care, develop clinical guidelines, and improve outcomes for aerodigestive patients
Seasonal and annual fluxes of nutrients and organic matter from large rivers to the Arctic Ocean and surrounding seas

estuaries and the Arctic Ocean as a whole, yet there is considerable uncertainty about the
magnitude of fluvial fluxes at the pan-arctic scale. Samples from the six largest arctic
rivers, with a combined watershed area of 11.3 x 106 km2, have revealed strong seasonal
variations in constituent concentrations and fluxes within rivers as well as large
differences among the rivers. Specifically, we investigate fluxes of dissolved organic
carbon, dissolved organic nitrogen, total dissolved phosphorus, dissolved inorganic
nitrogen, nitrate, and silica. This is the first time that seasonal and annual constituent
fluxes have been determined using consistent sampling and analytical methods at the pan
arctic scale, and consequently provide the best available estimates for constituent flux
from land to the Arctic Ocean and surrounding seas. Given the large inputs of river water
to the relatively small Arctic Ocean, and the dramatic impacts that climate change is
having in the Arctic, it is particularly urgent that we establish the contemporary river
fluxes so that we will be able to detect future changes and evaluate the impact of the
changes on the biogeochemistry of the receiving coastal and ocean systems.This work was supported by the National Science Foundation through grants

Design concepts for a next generation light source at LBNL
The NGLS collaboration is developing design concepts for a multi-beamline soft x-ray FEL array powered by a superconducting linear accelerator, operating with a high bunch repetition rate of approximately 1 MHz. The CW superconducting linear accelerator design is based on developments of TESLA and ILC technology, and is supplied by an injector based on a high-brightness, highrepetition- rate photocathode electron gun. Electron bunches from the linac are distributed by RF deflecting cavities to the array of independently configurable FEL beamlines with nominal bunch rates of ∼100 kHz in each FEL, with uniform pulse spacing, and some FELs capable of operating at the full linac bunch rate. Individual FELs may be configured for different modes of operation, including self-seeded and external-laser-seeded, and each may produce high peak and average brightness x-rays with a flexible pulse format, and with pulse durations ranging from femtoseconds and shorter, to hundreds of femtoseconds. In this paper we describe current design concepts, and progress in RandD activities. Copyright © 2013 CC-BY-3.0 and by the respective authors
Cucurbitacin I Inhibits Cell Motility by Indirectly Interfering with Actin Dynamics
Cucurbitacins are plant natural products that inhibit activation of the Janus kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) pathway by an unknown mechanism. They are also known to cause changes in the organization of the actin cytoskeleton. actin depolymerization experiments, cucurbitacin I had no effect on the rate of actin filament disassembly at the nanomolar concentrations that inhibit cell migration. At elevated concentrations, the depolymerization rate was also unaffected, although there was a delay in the initiation of depolymerization. Therefore, cucurbitacin I targets some factor involved in cellular actin dynamics other than actin itself. Two candidate proteins that play roles in actin depolymerization are the actin-severing proteins cofilin and gelsolin. Cucurbitacin I possesses electrophilic reactivity that may lead to chemical modification of its target protein, as suggested by structure-activity relationship data. However, mass spectrometry revealed no evidence for modification of purified cofilin or gelsolin by cucurbitacin I.Cucurbitacin I results in accumulation of actin filaments in cells by a unique indirect mechanism. Furthermore, the proximal target of cucurbitacin I relevant to cell migration is unlikely to be the same one involved in activation of the JAK2/STAT3 pathway
