BACKGROUND The histologic grade of a prostate needle-core biopsy specimen can determine whether a patient with prostate cancer is a candidate for radical prostatectomy or other treatment. Incorrect histologic grading can result in inappropriate treatment and possible liability. Thus, we conducted this study to determine the histologic-grading accuracy of prostate cancer needle-core biopsy speci...

A questionnaire study was carried out on 74 British Army patients who were awaiting aeromedical evacuation from the Former Republic of Yugoslavia. The study confirmed previous unpublished reports that 41 % of patients were being repatriated for exacerbation of pre-existing disease. Of these, 78 % had disease known to their medical officer, were considered to be outside limits for full fitness, ...

I estimate wage losses of displaced workers in the two countries and examine the relative contribution of two important sources of post-displacement wage adjustments. The first one relates to the loss of seniority-accumulated firmspecific earnings potent...

Every Summer, when English public examination results appear there is a debate within the media about whether ‘educational standards’ are changing. The above remarks are typical; the first reflects the suspicions of those who believe in a professional conspiracy to prove that standards of performance are rising, and the second reflects a politician’s determination to pretend that everything has...

The promise of punishment and reward in promoting public cooperation is debatable. While punishment is traditionally considered more successful than reward, the fact that the cost of punishment frequently fails to offset gains from enhanced cooperation has lead some to reconsider reward as the main catalyst behind collaborative efforts. Here we elaborate on the “stick vs. carrot” dilemma by stu...

This paper deals with changing parameters of the 1-median problem in the plane with Manhattan metric within certain bounds such that the optimal objective value of the 1-median problem with respect to the new values of the parameters is maximized. An O(n log n) time algorithm is suggested that is mainly based on a fast search and prune procedure.

The results of an experiment that shows that it is very simple to contaminate digital images with information that can later be extracted are presented. This contamination cannot be detected when the image is displayed on a good quality graphics workstation. Based on these results, it is recommended that image downgrading based on visual display of the image to be downgraded not be performed if...

From 1990 to 1997, over 710 thousand Russian Jews emigrated to Israel, increasing Israel’s working-age population by 15 percent. This paper argues that a canonical onesector neoclassical growth model explains both the short run and the medium run response of Israel’s economy to this shock. Specifically, we show that average effective wages of native Israelis fell and the return to capital incre...
