Several Shortcomings (several + shortcoming)
Selected AbstractsENTREPRENEURS' LOCATION CHOICE AND PUBLIC POLICIES: A SURVEY OF THE NEW ECONOMIC GEOGRAPHYJOURNAL OF ECONOMIC SURVEYS, Issue 5 2008Fabien Candau Abstract The aim of this paper is to survey what has been done by the New Economic Geography (NEG) on a regional scale in order to answer the three following questions: What are the predictions of the NEG concerning the future of regions in the triad? Are these predictions robust? What can be the optimal public policy on a regional and national scale in a world characterized by agglomeration, trade liberalization and mobility of entrepreneurs? In surveying the most recent contributions in this area, the paper sheds light on several shortcomings of the NEG literature in order to point out new directions for further research, with particular reference to studies concerning welfare and tax competition. [source] Recent advancement on polybenzoxazine,A newly developed high performance thermosetJOURNAL OF POLYMER SCIENCE (IN TWO SECTIONS), Issue 21 2009Yusuf Yagci Abstract Polybenzoxazine is a newly developed addition polymerized phenolic system, having a wide range of interesting features and the capability to overcome several shortcomings of conventional novolac and resole type phenolic resins. They exhibit (i) near zero volumetric change upon curing, (ii) low water absorption, (iii) for some polybenzoxazines Tg much higher than cure temperature, (iv) high char yield, (v) no strong acid catalysts required for curing, (vi) release of no byproduct during curing and also possess thermal and flame retarding properties of phenolics along with the mechanical performance. Though benzoxazine based materials possess several advantages, they have not yet became very attractive to the industries. To improve the mechanical properties and processibility several strategies have been reported including (i) synthesis of benzoxazine monomers with additional functionality, (ii) incorporation of benzoxazine in polymer chain, and (iii) benzoxazine based composites or alloys. In this article, we have discussed about the recent development of benzoxazine chemistry. © 2009 Wiley Periodicals, Inc.

In 2006 both instruments were merged to the "start-up allowance" (Gründungszuschuss). Since the bridging allowance has been evaluated as effective and efficient and the start-up-subsidy reached new target groups, the latest reform shows several shortcomings. First of all, an end of the start-up boom is to be expected with the newly attracted target groups not being reached anymore. Secondly, the design of the "start-up allowance" is suboptimal, where efficiency losses can be expected if participants aim at maximizing social transfers. First empirical evidence from data of 2007 supports most of these expectations. [source] Psychosocial issues in genetic testing for familial adenomatous polyposis: a review of the literaturePSYCHO-ONCOLOGY, Issue 8 2008K. F. L. Douma Abstract Objectives: Familial adenomatous polyposis (FAP) is characterized by the development of multiple adenomas in the colon that can lead to colorectal cancer. Being a carrier for FAP is hypothesized to have a negative impact on psychosocial well-being. This paper reviews the current literature on the psychosocial aspects of FAP. Methods: Four literature databases were used to identify all papers published between 1986 and 2007 about psychosocial and behavioral issues in FAP related to genetic testing. The following topics were reviewed: uptake and psychosocial impact of genetic testing, endoscopic screening behavior and psychosocial well-being in general. Results: Seventeen papers were identified. Across studies, genetic test uptake varied between 62 and 97%. Two out of three studies showed clinical levels of anxiety and/or depression after genetic testing. A minority of individuals were not reassured by a negative test result, and intended to continue endoscopic surveillance. Well-being (e.g. quality of life, family functioning) was found to be lower in some studies, while comparable to the general population in other studies. The studies had several shortcomings, such as mixed patient population (e.g. colorectal and breast cancer) and small sample sizes, and provided no information on other potentially important issues, such as psychosexual development. Conclusions: Future studies should employ larger sample sizes and standardized measurements. Additionally, future studies should address the long-term consequences of genetic testing for FAP, psychosexual development and consequences of FAP for the family as a whole.
