Determination of oxidative stress levels and some antioxidant enzyme activities in prostate cancer

In this study, the antioxidant enzyme activities such as (SOD, GSH, and CAT) and malondialdehyde (MDA) level which is the end product of lipid peroxidation, were determined from the serum samples taken from patients diagnosed with prostate cancer Van Yuzuncu Y?l University Medical Faculty of Educational Research and Training Hospital and ?stanbul Bagcilar Education Research Hospital. The SOD, GSH, and CAT activity of patient groups was found significantly lower than the healthy control group in patients with prostate cancer (p?相似文献   

Effect of childlessness on nursing home and home health care use

This study examines the likelihood of nursing home and home health care use for childless older Americans. Four research questions are addressed: (1) Are the childless elderly at a greater risk of nursing home and home health care use? (2) Is it childlessness per se or not having children with particular characteristics that affects the likelihood of using these formal long-term care services? (3) Does having additional children beyond the first one have a significant effect on the use of these services? (4) Are the effects of childlessness different on the likelihood of nursing home and home health care use? Longitudinal data from the first (1993) and second (1995) waves of the Asset and Health Dynamics Among the Oldest Old Survey (AHEAD) and multinomial logistic regression models are used for the analyses. Separate models are developed for women and men, each controlling for a variety of demographic, socioeconomic, and health-related characteristics of sample persons. Findings indicate childlessness as an important risk factor, especially for older women's use of nursing home services. Implications of findings for planning for long-term care needs of the baby boom generation are discussed.     

Linking Local Government Discretion and Accountability in Decentralisation

Decentralisation offers significant opportunities to improve government accountability by exerting stronger pressures both from below (demand) and above (supply). The literature contains many examples, however, where the potential has not been realised, partly because decentralisation reforms have often been introduced without thinking through their accountability implications. Even when accountability is taken into account, the efforts tend to emphasise either the supply or the demand side of the equation, but not both. Drawing on the sets of literature on fiscal, administrative and political decentralisation, this article presents a methodology for studying this.     

A new test for the extreme value distribution

In this paper a test statistic which is a modification of the W statistic for testing the goodness of fit for the two paremeter extreme value (smallest element) distribution is proposed. The test statistic Is obtained as the ratio of two linear estimates of the scale parameter. It Is shown that the suggested statistic is computationally simple and has good power properties. Percentage points of the statistic are obtained by performing Monte Carlo experiments. An example is given to illustrate the test procedure.     

Resolving inconsistencies in trends in old-age disability: Report from a technical working group

In September 2002, a technical working group met to resolve previously published inconsistencies across national surveys in trends in activity limitations among the older population. The 12-person panel prepared estimates from five national data sets and investigated methodological sources of the inconsistencies among the population aged 70 and older from the early 1980s to 2001. Although the evidence was mixed for the 1980s and it is difficult to pinpoint when in the 1990s the decline began, during the mid- and late 1990s, the panel found consistent declines on the order of 1%-2.5% per year for two commonly used measures in the disability literature: difficulty with daily activities and help with daily activities. Mixed evidence was found for a third measure: the use of help or equipment with daily activities. The panel also found agreement across surveys that the proportion of older persons who receive help with bathing has declined at the same time as the proportion who use only equipment (but not personal care) to bathe has increased. In comparing findings across surveys, the panel found that the period, definition of disability, treatment of the institutionalized population, and age standardizing of results were important to consider. The implications of the findings for policy, national survey efforts, and further research are discussed.     

Remittances,Business Cycles and Poverty: The Recent Turkish Experience

We investigate whether remittances sent to Turkey by Turkish workers living in Germany are countercyclical or procyclical with Turkish and German national outputs and discuss possible reasons underlying the resulting patterns and their implications. We also take up a previously unexplored issue and discuss poverty alleviation potential of remittances at a macroeconomic level by examining the statistical properties of any co‐movements between remittances cycles and cycles in consumption spending on food and durable goods in Turkey. Our results reveal that real remittance flows from Germany to Turkey move procyclically with the real output in Turkey, and are primarily driven by (largely independent of) the developments in the Turkish economy (German economy). We also find that remittances cycles remain procyclical to the consumption cycles throughout our sample period. This direct co‐movement between the two cycles becomes synchronous, however, only after a phase shift occurring around 1992, pointing to the increasing role of the level of economic activity in Turkey as the leading determinant of remittance receipts from Germany and the declining strength of consumption smoothing motive over time. Our results all together point out a low potential for remittances sent from Germany to reduce poverty in Turkey, at least as far as the past fifteen years are concerned.     

Analyzing Collision,Grounding, and Sinking Accidents Occurring in the Black Sea Utilizing HFACS and Bayesian Networks

This study examines and analyzes marine accidents that have occurred over the past 20 years in the Black Sea. Geographic information system, human factor analysis and classification system (HFACS), and Bayesian network models are used to analyze the marine accidents. The most important feature distinguishing this study from other studies is that this is the first study to analyze accidents that have occurred across the whole Black Sea. Another important feature is the application of a new HFACS structure to reveal accident formation patterns. The results of this study indicate that accidents occurred in high concentrations in coastal regions of the Black Sea, especially in the Kerch Strait, Novorossiysk, Kilyos, Constanta, Riva, and Batumi regions. The formation of grounding and sinking accidents has been found to be similar in nature; the use of inland and old vessels has been highlighted as important factors in sinking and grounding incidents. However, the sequence of events leading to collision-contact accidents differs from the sequence of events resulting in grounding and sinking accidents. This study aims to provide information to the maritime industry regarding the occurrence of maritime incidents in the Black Sea, in order to assist with reduction and prevention of the marine accidents.     

Islamophobia in Western Europe: A Comparative,Multilevel Study

Abstract

This study examines the prejudice against the Muslim immigrants in Western countries. The literature explains anti-Muslim prejudice almost exclusively by individual-level factors. Alternately, this study conducts a comparative, multilevel analysis to include cross-level processes as well. The analysis covers 16 Western European countries, and the data come primarily from the fourth wave of the European Values Study in 2008. Results offer strong support for the relevance of the country-level factors to individual prejudice, while confirming the findings of the major individual-level perspectives. More specifically, the findings suggest that the individuals who live in countries with (1) an official religion or (2) a liberal citizenship regime are more likely to be tolerant toward Muslims. The study also offers some support for the contact hypothesis.     

Identification of a princess under incomplete information: an amarna story

This article presents four analyses of an interaction between the middle-Bronze Age Pharaoh Nibmuarea and the Babylonian king Kadashman-Enlil as described in the Amarna letters (Moran [1992] The Amarna Letters, The Johns Hopkins Universiy Press, Baltimore, Maryland). Intent on denying the Pharaoh his daughter in marriage, the Babylonian king was faced with the choice of sending messengers who could ('dignitaries') or could not identify ('non-dignitaries') his missing sister in the Pharaoh's court. Intent on marrying the king's daughter, the Pharaoh was faced with the choice of showing the sister or showing someone else. Based on the assumption of complete information (game 1), the analysis revealed a dominant-strategy equilibrium: Nibmuarea shows the sister and Kadashman-Enlil sends non-dignitaries. Based on the assumption of one-sided incomplete information (Pharaoh's misperception; game 2), the analysis revealed that the Pharaoh had a dominant strategy of showing the sister irrespective of whether the king is keen or reluctant to learn about his sister's fate. Based on the assumption of one-sided incomplete information (Kadashman-Enlil's misperception; game 3), the analysis revealed that if non-dignitaries are sent, the Pharaoh prefers showing someone other than his sister. Based on the assumption of two-sided incomplete information (game 4), the Pharaoh finds it more beneficial to present the sister irrespective of whether his intentions are genuine or feigned. With incomplete information, it is difficult to judge the other's intentions; the cost of being caught cheating by not showing the sister to knowledgeable messengers was quite high. These analyses highlight the strategic uncertainty that characterized this Bronze-Age interaction.     

Effects of Random Yield in Remanufacturing with Price‐Sensitive Supply and Demand

In this study, we investigate the effects of recovery yield rate on pricing decisions in reverse supply chains. Motivated by the automotive parts remanufacturing industry, we consider an end‐of‐life product from which a particular part can be recovered and remanufactured for reuse, and the remainder of the product can be recycled for material recovery. Both the supply of end‐of‐life products and demand for remanufactured parts are price‐sensitive. Yield of the recovery process is random and depends on the acquisition price offered for the end‐of‐life products. In this setting, we develop models to determine the optimal acquisition price for the end‐of‐life products and the selling price for remanufactured parts. We also analyze the effects of yield variation to the profitability of remanufacturing, benefits of delaying pricing decisions until after yield realization, and value of perfect yield rate information.
