We consider the issue of testing a time series for a unit root in the possible presence of a break in a linear deterministic trend at an unknown point in the series. We propose a new break fraction estimator which, where a break in trend occurs, is consistent for the true break fraction at rate Op(T). Unlike other available estimators, however, when there is no trend break our estimator converg...

background and objectives: efficient hospital management requires appropriate cost and price strategies. informed decision on costs and prices of healthcare services needs estimation of costs of unit services using microeconomic techniques. there is lack of knowledge and skills for such costing methods in the healthcare sector of developing countries such as iran. this study aims at detail desc...

Figure 1: The depth to diameter ratio of craters smaller than a certain size is a constant, as predicted by the Maxwell Zmodel. Below a break point (10 km for the Moon), the ratio follows a power law, decreasing as size increases [Hiesinger, 2006, Sharpton, 1994]. Source: [Hiesinger, 2006]. The uniformity of the phenomena suggests that there are two excavation processes, one for features with a...

A systematic method of designing TSC checker for Q class (even code length) of Borden’s code [l] is proposed, where a modular approach is used. In a comparative study, it is found that the proposed method is much better than [2,3] and it has a larger capability than [4,5] in designing the checker. For instance, the 3/12 code in C(12,2) can be identified in one of four ways, corresponding to PT’...

To determine the economic impact of adult chronic tonsillitis and the economic improvement from adult tonsillectomy, we studied patients who underwent adult tonsillectomy for chronic tonsillitis with the Glasgow Benefit Inventory and a questionnaire for disease severity parameters before and after tonsillectomy. The economic impact of chronic tonsillitis and adult tonsillectomy were computed wi...

AIM Academic research investigating health care costs in the Palestinian region is limited. Therefore, this study examines the costs of the cardiac catheterization unit of one of the largest hospitals in Palestine. We focus on costs of a cardiac catheterization unit and the increasing number of deaths over the past decade in the region due to cardiovascular diseases (CVDs). METHODS We employ ...
