Research on smoking has increased in the past several years, and many new therapeutic modalities have been developed. Primary intervention for smoking cessation begins with systematic identification of smokers and a formal diagnosis of nicotine dependence. Providing self-help brochures without clinical advice has marginal efficacy, but these can be useful as an adjunct to clinician intervention...

Traveler's diarrhea (TD) is a crucial area for research, as it affects millions of tourists each year and creates a large economic burden. More than 60% of TD cases are caused by a variety of bacterial enteropathogens: diarrhea-producing Escherichia coli, Shigella, Campylobacter, Salmonella, Aeromonas, Plesiomonas, and noncholera Vibrios. Noroviruses are also an important cause of morbidity amo...

Healthcare PPPs where clinical services as well as infrastructure are delivered by the private sector are coming under the spotlight as governments seek to achieve value for money in health budgets. Existing examples are being reported as successful, however this article urges caution as a closer look at the evidence shows that handing over control of service delivery to the private sector is d...

Several new developments are likely to occur in the cotton industry during the next decade. Obviously, the impacts of emerging technologies will vary among different regions of the world. However, any new development will likely impact most other cotton-growing areas. To gain a broader perspective, I have consulted experts in various disciplines for assistance. I will summarize my perspectives ...

The logical, scientific and realistic analysis of the new developments in Iraq, due to various indicators such as the power of Shiite currents, the existence of influential leaders and the presence of foreign invaders, inevitably leads us to consider only the foreign invaders' perspective, here in this article. In fact, understanding Iraq's developments after Saddam will be a significant part o...

With regard to epizootiology, diseased pigs are the major source of direct infection, while indirect spread is mainly caused by pork pro­ ducts and mechanical vectors. Information about the role of virus car­ riers in transmission of the infection is insufficient, but the role of ticks (Ornithodorus genus) and of wild pigs as virus reservoirs is well docu­ mented. The incidence and distribution...

Heller. Department of Management Studies, The Polytechnic, Regent Street, W.l. 75 pp. 5s. In these columns I have carped often enough at the rising price of slight and uninspiring books : it is then a pleasure to welcome this pamphlet as exceedingly good value for money to anyone interested in management in industry. It consists of four lectures given to the Polytechnic Department of Management...

Iterated rounding is a relatively recent technique in algorithm design, that despite its simplicity has led to several remarkable new results and also simpler proofs of many previous results. We will briefly survey some applications of the method, including some recent developments and giving a high level overview of the ideas. 1998 ACM Subject Classification F.2.2 Nonnumerical Algorithms and P...

from the hospital. The pediatrician represents the child and his family and should be an active participant in all major discussions concerning the child. He decides when and to whom the patient should be referred for evaluation. He often initiates therapy, particularly in urgent situations. He should not decide when specialized diagnostic procedures are to be performed nor should he determine ...

The mizar language aims to capture mathematical vernacular by providing a rich language for mathematics. From the perspective of a user, the richness of the language is welcome because it makes writing texts more “natural”. But for the developer, the richness leads to syntactic complexity, such as dealing with overloading. As part of the larger project of open-sourcing the mizar codebase, the m...
