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   

Disability in Somaliland

Civil war lasting into the 1990s destroyed much of Somalia's economic, political and social structures, and conflict still continues in the southern areas of the country. In 1991, the northwest region declared itself the Independent Republic of Somaliland, established a government in Hargeisa and is struggling to rebuild an infrastructure. It is one of the poorest countries in the world, ranking high on the UN hunger index, and is the third most heavily land-mined country. One of the most disadvantaged groups of people are the disabled, although there is little general information about numbers and kinds of disability, and few social and medical services. This article presents some limited information about the extent of the nature of disability, and local efforts to improve the lives of disabled children and adults. It reports projects funded by non-government organisations, and concentrates on a seminar held in early 2002 attended by a group of disabled people who made their voices heard.     

The Effects of Spousal Health on the Decision to Smoke: Evidence on Consumption Externalities, Altruism and Learning Within the Household

Married individuals are healthier than single individuals though the reasons are not well understood. Individuals with spouses/or partners are less likely to smoke. We explore the relationship between health and marital status by analyzing three potential channels through which marriage affects smoking, i.e., consumption externalities (one spouse's smoking affects the other spouse's welfare), altruism (one spouse reduces smoking in response to the other spouse's bad health), and learning about risks of smoking from the health experience of one's spouse. We find spousal health does not affect smoking due to altruism or learning within the household but do find evidence for consumption externalities.     

Characterizations of gamma,inverse Gaussian,and negative binomial distributions via their length-biased distributions

A general form for characterizing inverse Gaussian and Wald distributions, based on their respective length-biased distributions, is introduced. Further results for characterizations of the gamma distribution, the negative binomial distribution and some mixtures of them by using their lengthbiased distributions are establised.     

Marriage and its transition in Bangladesh

The author examines developments in marriage patterns in Bangladesh in light of social, cultural, and economic conditions. Previous literature on the subject is used to discuss Muslim marriage, Hindu marriage, child marriage, mate selection and social mobility, and the question of a marriage squeeze. "The analysis presents evidence that the society is experiencing a change in its family formation, mating process and family type. This transition is to some extent towards the characteristics of [the] Western World, but in a poor economy. Part of this transition is due to the effect of modernization and part due to increasing poverty."     

On the modified Burr IV model for hydrological events: development,properties, characterizations and applications

We introduce a new distribution for modeling extreme events about frequency analysis called modified Burr IV (MBIV) distribution. We derive the MBIV distribution on the basis of the generalized Pearson differential equation. The proposed model turns out to be flexible: its density function can be symmetrical, right-skewed, left-skewed, J and bimodal shaped. Its hazard rate has shapes such as bathtub and modified bathtub, increasing, decreasing, and increasing-decreasing-increasing. To show the importance of the MBIV distribution, we establish various mathematical properties such as random number generator, sub-models, moments related properties, inequality measures, reliability measures, uncertainty measures and characterizations. We utilize the maximum likelihood estimation technique to estimate the model parameters. We assess the behavior of the maximum likelihood estimators (MLEs) of the MBIV parameters via a simulation study. Five data sets related to frequency analysis are considered to elucidate the significance of the MBIV distribution. We show that the MBIV model is the best model to analyze data for hydrological events, motivating its high level of adaptability in the applied setting.KEYWORDS: Characterizations, elasticity function, moments, maximum likelihood estimator, reliability     

Choices at various levels of uncertainty: An experimental test of the restated diversification theorem

Our “Restated diversification theorem” (Skogh and Wu, 2005) says that risk-averse agents may pool risks efficiently without assignment of subjective probabilities to outcomes, also at genuine uncertainty. It suffices that the agents presume that they face equal risks. Here, the theorem is tested in an experiment where the probability of loss, and the information about this probability, varies. The result supports our theorem. Moreover, it tentatively supports an evolutionary theory of the insurance industry—starting with mutual pooling at uncertainty, turning into insurance priced ex ante when actuarial information is available.     

How Australian Female Muslim Students Interpret Challenges in High School Sports

Abstract

The present study focuses on the experiences of female Muslim students in school sporting activities in Australian public high schools. Specifically, the study examines how the students interpret their engagement in relation to their Islamic background. The study aims to provide deeper understanding and greater awareness of female Muslim students’ participation in sporting activities within the public high school environment and the challenges they may face. The study employed critical race and social identity theories as an analytical framework. In addition, the study utilized qualitative research methods. Semi-structured interviews were conducted with 11 female Muslim students and 4 teachers responsible for sporting activities in school. The findings of the study reveal that despite a variety of sporting activities provided by Australian public high schools, some of these activities were challenging for Muslim girls to participate in. The study also found that there is a strong relationship between students’ Islamic background and their participation in schools sporting activities. The study recommends that educators and teachers who work with youth from different background are provided training on equity issues arising from ethnicity, race, culture, religion and other identity categories.     

Reducing attitudes of prejudice and discrimination through literature: a quasi-experiment on the upper key-stage 2 students of the British schools in Karachi,Pakistan

This study aims to explore the efficacy of literature relating to Anne Frank to reduce children’s attitudes of prejudice and discrimination with respect to specific dimensions, including ethnicity and race, religion and gender. A quasi-experiment was employed with pre-post control design. The sample consisted of 100 students of the upper key-stage 2 (UKS2) level, recruited from the two British schools in Karachi. These schools represented an Experimental Group (EG) and a matched Comparison Group (CG). A research instrument titled ‘Muggles world of differences’ (MWD) was developed and validated. It was administered on CG and EG, both before and after intervention. The intervention plan ‘Reading of Young Anne’s Literature’ (ROYAL) was developed based on selected readings from Anne Frank related literature (AFL). Intervention was provided to EG, while CG studied similar concepts using a more standard method. Results of the pretest revealed a high level of prejudice and discrimination in both the EG and CG, with no significant difference (p > 0.05) in the overall scores, as well as in the specific content domains. However, the post-test of the two groups revealed that the students in the EG had outperformed their CG counterparts in overall MWD scores, as well as in specific content domains. The difference was found to be significant (p < 0.05) with the large effect size (r = ?0.63). Results support the efficacy of teaching Anne Frank related literature in reducing attitudes of prejudice and discrimination.
