Determinants of online shopping: Examination of an early‐stage online market
Authors: Liebermann Yehoshua , Stashevsky Shmuel 
Published: December 2009

AbstractA conceptual framework intended to predict the number of online purchases made by Internet users in an early stage market is presented and examined using data collected in Israel. Those more likely to report buying online saw low costs and substantial benefits associated with e‐shopping. They were experienced Internet users who valued online information searching. They were also more likely to shop over the phone, but did not especially like to go shopping. Finally, they tended to be the primary purchaser in the household. Our framework enhances understanding of the factors affecting consumers' online shopping behaviour, aides in profiling typical electronic shoppers, and may help practitioners develop more personalized marketing programs to increase e‐commerce sales.

Annual report to the nation on the status of cancer, 1975‐2006, featuring colorectal cancer trends and impact of interventions (risk factors, screening, and treatment) to reduce future rates

Published: December 2009

AbstractBACKGROUND.The American Cancer Society, the Centers for Disease Control and Prevention (CDC), the National Cancer Institute (NCI), and the North American Association of Central Cancer Registries (NAACCR) collaborate annually to provide updated information regarding cancer occurrence and trends in the United States. This year's report includes trends in colorectal cancer (CRC) incidence and death rates and highlights the use of microsimulation modeling as a tool for interpreting past trends and projecting future trends to assist in cancer control planning and policy decisions.METHODS.Information regarding invasive cancers was obtained from the NCI, CDC, and NAACCR; and information on deaths was obtained from the CDC's National Center for Health Statistics. Annual percentage changes in the age‐standardized incidence and death rates (based on the year 2000 US population standard) for all cancers combined and for the top 15 cancers were estimated by joinpoint analysis of long‐term trends (1975‐2006) and for short‐term fixed‐interval trends (1997‐2006). All statistical tests were 2‐sided.RESULTS.Both incidence and death rates from all cancers combined significantly declined (P < .05) in the most recent time period for men and women overall and for most racial and ethnic populations. These decreases were driven largely by declines in both incidence and death rates for the 3 most common cancers in men (ie, lung and prostate cancers and CRC) and for 2 of the 3 leading cancers in women (ie, breast cancer and CRC). The long‐term trends for lung cancer mortality in women had smaller and smaller increases until 2003, when there was a change to a nonsignificant decline. Microsimulation modeling demonstrates that declines in CRC death rates are consistent with a relatively large contribution from screening and with a smaller but demonstrable impact of risk factor reductions and improved treatments. These declines are projected to continue if risk factor modification, screening, and treatment remain at current rates, but they could be accelerated further with favorable trends in risk factors and higher utilization of screening and optimal treatment.CONCLUSIONS.Although the decrease in overall cancer incidence and death rates is encouraging, rising incidence and mortality for some cancers are of concern.

Histologic evaluation of metastases in renal cell carcinoma with sarcomatoid transformation and its implications for systemic therapy

AbstractBACKGROUND:Sarcomatoid features in renal cell carcinoma may represent an aggressive subclone arising from the primary tumor. The patterns of metastases for these tumors were evaluated to determine if sarcomatoid features were retained at metastasis and whether the percentage of sarcomatoid features in the primary tumor influenced spread.METHODS:All patients with sarcomatoid features found at nephrectomy with synchronous or metachronous resection of metastases were evaluated. The histology, grade, and percentage of sarcomatoid features in the primary and metastatic site were recorded. The association between percentage of sarcomatoid features, grade, histology, and pattern of metastases was evaluated.RESULTS:Thirty‐two patients were identified with sarcomatoid features and resected metastases. Fifty‐two metastatic sites were evaluated. A single histologic appearance (sarcomatoid or carcinomatoid) was present in 50 of 52 sites (96%). Thirty sites (58%) demonstrated only a sarcomatoid pattern, whereas 20 (38%) contained only a carcinoma pattern. Histology and carcinoma grade did not influence metastatic pattern; however, greater percentage of sarcomatoid features was associated with the presence of distant sarcomatoid histology. A cutoff of 30% sarcomatoid features in the primary tumor was useful in predicting systemic sarcomatoid histology.CONCLUSIONS:Sarcomatoid elements are frequently observed in the metastases of primary tumors with sarcomatoid features, and these metastases generally contain a solitary pattern supporting the subclone hypothesis. However, both components can metastasize in the same patient. The percentage of sarcomatoid features influences the pattern of spread, and patients with >30% sarcomatoid features in the primary tumor frequently have distant sarcomatoid histology. This cutpoint may be helpful for inclusion criteria for future clinical trials. Cancer 2010. © 2009 American Cancer Society.
A framework for scalable, parallel performance monitoring
Authors: Nataraj Aroon , Malony Allen D. , Morris Alan , Arnold Dorian C. , Miller Barton P. 
Published: December 2009

AbstractPerformance monitoring of HPC applications offers opportunities for adaptive optimization based on the dynamic performance behavior, unavailable in purely post‐mortem performance views. However, a parallel performance monitoring system must have low overhead and high efficiency to make these opportunities tangible. We describe a scalable parallel performance monitor calledTAUoverMRNet (ToM), created from the integration of the TAU performance system and the Multicast Reduction Network (MRNet). The integration is achieved through a plug‐in architecture in TAU that allows the selection of different transport substrates to offload the online performance data. A method to establish the transport overlay structure of the monitor from within TAU, one that requires no added support from the job manager or application, is presented. We demonstrate the distribution of performance analysis from the sink to the overlay nodes and the reduction in the large‐scale profile data that could, otherwise, overwhelm any single sink. The results show low perturbation and significant savings accrued from reduction at large processor‐counts. Copyright © 2009 John Wiley & Sons, Ltd.
Conductivity of Poly(pyrrole)‐Poly(styrene sulfonate) Core–Shell Nanoparticles
Authors: Mpoukouvalas Konstantinos , Wang Jianjun , Wegner Gerhard 
Published: December 2009

AbstractThe dielectric properties of poly(styrene) nanoparticles decorated at their surfaces with poly(styrene sulfonate) [PSS] brushes and subsequently loaded with polypyrrole (PPy) were studied. These film‐forming materials which may serve as hole‐injection layers in organic light‐emitting diodes, exhibit a core–shell‐type morphology with a core of electrically insulating poly(styrene) and a shell consisting of a corona of PSS chains which form the matrix in which the electrically conducting complex of PPy and PSS is embedded. This conducting complex exists in form of domains of nanoscale dimensions. Thin compressed pellets of these nanoparticles were studied using mainly impedance spectroscopy. Measurements were carried out in the temperature range between 123 and 453 K and frequency range from 10−1to 106Hz. While earlier studies were centered around the effect of polypyrrole volume fraction on the conductivity films and pellets composed of these nanoparticles, the present study reveals in which way the conductivity can be modified by exchange of the mobile inorganic counter ions of PSS. Besides the free‐acid form (H+), the Li+‐, Na+‐ and Cs+‐salts of PSS were investigated. The PPy volume fraction was the same for all PPy/PSS core–shell nanoparticles. The distance for phonon‐assisted hopping between next‐neighbor polypyrrolium chains is influenced by the presence of these inorganic cations. For all samples containing PPy, a transition from insulating to conducting behavior in the range of 300‐350 K was found. Using the fluctuation‐induced tunneling model, the average tunneling distance, as well as the potential energy barrier separating neighboring conducting grains was estimated. Finally, a detailed analysis of the dielectric spectra suggests the localization length of the charge carriers to be about 0.33 nm.
Polarizable Atomistic Calculation of Site Energy Disorder in Amorphous Alq3
Authors: Nagata Yuki 
Published: December 2009

AbstractA polarizable molecular dynamics simulation and calculation scheme for site energy disorder is presented in amorphous tris(8‐hydroxyquinolinato)aluminum (Alq3) by means of the charge response kernel (CRK) method. The CRK fit to the electrostatic potential and the tight‐binding approximation are introduced, which enables modeling of the polarizable electrostatic interaction for a large molecule systematically from an ab initio calculation. The site energy disorder for electron and hole transfers is calculated in amorphous Alq3 and the effect of the polarization on the site energy disorder is discussed.
