It is demonstrated that the effectiveness of the pricing and standards approach (PSA) to emission control is seriously impaired by imperfect tax compliance of regulated firms, contrary to literature reports. If there exists a firm that attempts to commit 100% tax evasion, PSA fails to minimize the social abatement cost, and when all firms take the risk of total tax evasion, PSA no longer reduces emissions. Heavy taxes give firms incentive to cheat, so the government is only able to adopt PSA when target levels of total emission reductions are relatively small. © 2008, Springer Japan. Source

PURPOSE: The purpose of this study is to evaluate the accuracy of 2-deoxy-2-[F-18]fluoro-D: -glucose-positron emission tomography (FDG-PET)/computed tomography (CT) with intravenous contrast for depiction of recurrent pancreatic cancer, compared with PET/non-enhanced CT and CT. PROCEDURE: Forty-five patients previously treated for pancreatic cancer underwent PET/CT for suspected recurrence. Lesion status was determined on the basis of histopathology and radiological imaging follow-up. RESULTS: Patient-based analysis showed that sensitivity, specificity, and accuracy of PET/contrast-enhanced CT were 91.7%, 95.2%, and 93.3%, respectively, whereas those of PET/non-enhanced CT were 83.3%, 90.5%, and 86.7%, respectively, and those of enhanced CT were 66.7%, 85.7%, and 75.6%, respectively. In 21 patients whom the final diagnosis was obtained from the histopathologic examination, those figures of PET/contrast-enhanced CT were 94.7%, 50.0%, and 90.4%, respectively. The sensitivity of PET/contrast-enhanced CT in detecting local recurrence, abdominal lymph node metastasis, and peritoneal dissemination were 83.3%, 87.5%, and 83.3%, respectively. CONCLUSION: PET/contrast-enhanced CT is an accurate modality for assessing recurrence of pancreatic cancer. Source

The GPM mission is specifically designed to unify and advance precipitation measurements from a constellation of research and operational microwave sensors. NASA and JAXA have successfully deployed the GPM Core Observatory on February 28, 2014, building upon the success of TRMM launched by NASA of the US and JAXA of Japan in 1997. The observatory carries the first spaceborne dual-frequency phased array precipitation radar, the DPR, operating at Ku and Ka bands and a conical-scanning multi-channel microwave imager known as the GMI. This sensor package is an extension of the TRMM instruments, which focused primarily on heavy to moderate rain over tropical and subtropical oceans. The GPM sensors will extend the measurement range attained by TRMM to include light-intensity precipitation and falling snow, which accounts for a significant fraction of precipitation occurrence in the middle and high latitudes.

Background: Creola bodies (CrBs) in the sputum are an indicator of respiratory epithelial damage and appear specifically in bronchial asthma. We studied the presence and clinical significance of CrBs in infants with respiratory syncytial virus (RSV) bronchiolitis contributing to the development of asthma. Methods: Aspirated sputum samples were collected from 33 infants admitted with acute RSV bronchiolitis. The samples were then examined for the presence (or absence) of CrBs and classified into the RSV-CrB group and RSV-non-CrB group. Eosinophil cationic protein (ECP) and neutrophil elastase (NE) concentrations in the sputum were compared between the two groups. History of wheeze and asthma was collected at 2 years and 5 years after their discharge from hospital. Results: CrBs were detected in 23 of the 33 subjects (69.7%). No significant difference in the ECP and the NE concentration were observed between the RSV-CrB group and RSV-non-CrB group. A significant relationship was observed between CrBs detected with RSV bronchiolitis and the development of recurrent wheezing and asthma (after 2 years: relative risk [RR], 3.09; p = 0.002; after 5 years: RR 7.00; p = 0.019). Conclusions: These findings suggest that a high rate of CrBs in the sputum is present in infants with RSV bronchiolitis, and notably the CrBs are associated with the progression to recurrent wheezing and asthma. © 2010 Japanese Society of Allergology.

Energy Policy | Year: 2013

This paper attempts to measure consumers' perceived net benefits (or net costs) of energy-saving measures in using energy-consuming durable goods. Using the estimated net costs and the volume of CO2 reduced by the measures, a marginal abatement cost (MAC) curve for the average household's CO2 emissions is produced. An analysis using the curve suggests that in order to provide households with an incentive to take actions that can lead to CO2 emission reductions in using energy-consuming durables, a high level of carbon price is needed. In addition, a regression analysis reveals that the net benefits of the measures are larger for households that put a higher priority on energy saving, for those living in detached houses, for those with a smaller number of persons living together, and for those with less income. The result of the analysis using the MAC curve may suggest that promoting energy-saving behavior will require not only a policy to provide economic incentives but also interventions to influence psychological factors of household behavior. © 2013 Elsevier Ltd.
