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   

Exclusion and vulnerability on public transit: experiences of transit dependent riders in Portland,Oregon

In urban areas, the inequitable distribution of transit systems and services has been shown to reproduce safety and environmental risks – potentially exacerbating preexisting inequities. Thus, how vulnerable populations access and utilize public transportation is of critical concern to urban scholars. This paper utilizes focus group data to explore how transit-dependent (particularly low-income) riders engage with the public transit system in Portland, Oregon. We illustrate specific ways in which transit-dependent riders experience marginalization and exclusion. We find that certain groups, particularly mothers with young children and those with disabilities are not well served by a public infrastructure oriented toward an ‘ideal rider’ who is an economically stable, able-bodied, white, male commuter. We conclude that a public infrastructure meant to serve all riders equitably, yet which fails to consider the unique experiences of marginalized transit users risks further amplifying existing social vulnerabilities and reinforcing gender, racial, and class inequalities.     

Wiki-worthy: collective judgment of candidate notability

The use of socio-technical data to predict elections is a growing research area. We argue that election prediction research suffers from under-specified theoretical models that do not properly distinguish between ‘poll-like’ and ‘prediction market-like’ mechanisms understand findings. More specifically, we argue that, in systems with strong norms and reputational feedback mechanisms, individuals have market-like incentives to bias content creation toward candidates they expect will win. We provide evidence for the merits of this approach using the creation of Wikipedia pages for candidates in the 2010 US and UK national legislative elections. We find that Wikipedia editors are more likely to create Wikipedia pages for challengers who have a better chance of defeating their incumbent opponent and that the timing of these page creations coincides with periods when collective expectations for the candidate's success are relatively high.     

“They give you back that dignity”: understanding the intangible resources that make a transitional house a home for homeless families

Approximately 33% of the homeless population in 2017 were families with children. Researchers have argued for interventions and services to employ an ecological perspective to mitigate some of the unintentional harm inherent in existing programs designed to serve homeless families. This paper utilized a case study of a transitional housing program to (1) determine how well the program met recommendations informed by the ecological perspective and (2) explore underlying themes across recommendations. Past and current residents of a transitional housing program participated in semi-structured interviews as part of a program evaluation. Interviews were deductively and inductively coded to meet aims 1 and 2, respectively. Residents identified several aspects of the program that met the ecological perspective recommendations including culturally-responsive services, trauma-based services, and social and community connections. Major underlying themes spanning across recommendations included interpersonal resources (caring, sense of belonging), empowerment resources (advocacy, family preservation), impact on family (family life, positive youth development), and communication. This case study, through the analysis of residents’ perspectives, highlights the important role of transitional housing programs in providing a supportive, empathetic, empowering, and home-like environment that gives residents “back that dignity” so they are emotionally and physically prepared to successfully transition to permanent housing.     

Learning Patterns in Social Skills Training Programs: An Exploratory Study

While Social Skills Training programs have been shown to improve the social skills of children with Disruptive Behaviour Disorders, the pattern of change in the participants’ learning during the training period remains unknown. Identifying this pattern could assist in determining whether more or less training hours are required to maximize the benefits of such programs within available resources. The current study aimed to replicate the social skills improvements found in previous research, and to explore the pattern of improvements in social knowledge and social performance that occurs during a Social Skills Training program. Two groups of eight males with behavioural problems attended 14 one-hour sessions of Social Skills Training. Multisources, multisettings and multimethods were used to measure social knowledge and social performance across five test phases. Multivariate analyses did not support previous findings showing overall improvements in social knowledge and social performance. Patterns of learning were not found to be consistent across different measures.     

Evaluating the Significance Test When the Correlation Coefficient is Different from Zero in the Test of Hypothesis

Sample size and correlation coefficient of populations are the most important factors which influence the statistical significance of the sample correlation coefficient. It is observed that for evaluating the hypothesis when the observed value of the correlation coefficient's r is different from zero, Fisher's Z transformation may be incorrect for small samples especially when population correlation coefficient ρ has big values. In this study, a simulation program has been generated for to illustrate how the bias in the Fisher transformation of the correlation coefficient affects estimate precision when sample size is small and ρ has big value. By the simulation results, 90 and 95% confidence intervals of correlation coefficients have been created and tabled. As a result, it is suggested that especially when ρ is greater than 0.2 and sample sizes of 18 or less, Tables 1 and 2 can be used for the significance test in correlations.     

A critical exploration of the school context for young adolescents completing primary education

Many schools have adopted relational approaches to attend to the social context in which learning transpires. More recently however, such approaches and their supporters have been criticized for not examining the school context in its entirety and the student experience within this context. The current research sought to critically explore young adolescents’ experiences within the context of their school. Fifteen year seven students in an Australian primary school were interviewed about their experiences of their school context. The data were analysed using a thematic analysis and a question-ordered matrix was constructed to aid the detection of themes and sub-themes from the data. Three major themes were identified as a result. These included: the people within the school context, the social roles of the adolescents’, and the values the school espouses. These findings suggest that there are a number of factors in addition to relational aspects within the school context that impact on young adolescents. This exploratory qualitative study offers a ‘counter adult-centric’ view of young adolescents’ experiences within their school. It also illustrates the potential value in transforming the school context to provide opportunities to experience influence, responsibility, self-determination, meaningful participation and community within the school.
