Currently, no effective tool exists for screening or early diagnosis of head and neck squamous cell carcinoma (HNSCC). Here, we describe an approach for cancer detection based on analysis of patterns of serum immunoreactivity against a panel of biomarkers selected using microarray-based serologic profiling and specialized bioinformatics. We biopanned phage display libraries derived from three d...
OBJECTIVE To compare the reliability and validity of two classification systems used to evaluate the quality of mammograms: PGMI ('perfect', 'good', 'moderate' and 'inadequate') and EAR ('excellent', 'acceptable' and 'repeat'). SETTING New South Wales (Australia) population-based mammography screening programme (BreastScreen NSW). METHODS Thirty sets of mammograms were rated by 21 radiograp...
We develop a set of nonparametric rank tests for non-stationary panels based on multivariate variance ratios which use untruncated kernels. As such, the tests do not require the choice of tuning parameters associated with bandwidth or lag length and also do not require choices with respect to numbers of common factors. The tests allow for unrestricted cross-sectional dependence and dynamic hete...
This paper examines the effect of value-added taxes (VATs) on international trade. Destination-based VATs are commonly thought to encourage exports, since exports are exempt from tax while imports are taxed. Economic theory implies that exchange rate adjustment prevents destination-based VATs from affecting exports and imports, since exchange rate appreciation completely undoes the effects of i...
This paper takes a step toward identifying the ultimate drivers of productivity growth at the industry level. Based on Neoclassical and New Growth Theory we develop an empirical methodology that allows us to test for the fundamental drivers of industry productivity growth. We present two sets of industry classifications, one based on ICT intensity and another based on innovation types. Using OE...
How does a major financial network innovation influence firm performance? Despite much speculation we have little hard quantitative evidence about the impact of technology diffusion in financial services. In this paper we use the entire adoption history for SWIFT (the Society for Worldwide Interbank Financial Telecommunication standards provider and messaging carrier) matched to bank-level pane...
This paper further tests Romer’s (1993) extension of Kydland and Prescott’s (1977) predictions for dynamic-inconsistency problems in open economies. In a panel data set of developed and developing countries from 1973 to 1998, I find that openness does not play a role in restricting inflation in the short-run. On the other hand, a fixed exchange-rate regime plays a significant role. The results ...
PURPOSE Patients with metastatic adenocarcinoma of unknown origin are a common clinical problem. Knowledge of the primary site is important for their management, but histologically, such tumors appear similar. Better diagnostic markers are needed to enable the assignment of metastases to likely sites of origin on pathologic samples. EXPERIMENTAL DESIGN Expression profiling of 27 candidate mar...
Rapid advances in generating new mouse genetic models for lung neoplasia provide a continuous challenge for pathologists and investigators. Frequently, phenotypes of new models either have no precedents or are arbitrarily attributed according to incongruent human and mouse classifications. Thus, comparative characterization and validation of novel models can be difficult. To address these issue...
To improve the detection of the economic ”danger zones” from which severe banking crises emanate, this paper introduces classification tree ensembles to the banking crisis forecasting literature. I show that their out-of-sample performance in forecasting binary banking crisis indicators surpasses current best-practice early warning systems based on logit models by a substantial margin. I obtain...
