Hurst Exponent Analysis of Financial Time Series

Statistical properties of stock market time series and the implication of their Hurst exponents are discussed.Hurst exponets of HJIA (Dow Jones Industrial Average)components are tested using re-scaled range analysis.In addition to the original stock return series,the linear prediction errors of the daily returns are also tested.Numerical results show that the Hurst exponent analysis can provide some information about the statistical properties of the financial time series.     

Financial Planning‐Chemistry as a Special Case

Although many women now hold qualifications that in the past guaranteed an academic appointment, few jobs are available in universities. In an unrestrained labour market, the sex ratio of academics in Australian universities is unlikely to change much over the next 10 to 15 years. The likely impact of affirmative action policies and practices is discussed.

Prediction of Post-High School Destination Choice from Curriculum,Financial Need,and Students’ Rating of Parents’ Wishes for Post-High School Occupation

Data from a survey of 2,431 students attending high schools in Hawaii indicated that students agreed with their parents’ wishes for post-high school occupation. Females tended to choose more academic post-high school destinations than males. An inverse relationship between academic high school curricula and post-high school academic goals was found, probably due to the fact that females were academically upwardly mobile. The need for financial assistance tended to decrease academic aspirations. It was concluded that knowledge of parental values, differences in academic aspirations between males and females, financial need, and a student’s high school curriculum would be valuable in helping students select post-high school destinations.     

Promoting Financial Literacy and Latino Males’ Success at Community Colleges

Latino males across the country enroll in community colleges with the purpose of obtaining an educational degree, which could lead to accomplishing professional and personal aspirations. Even if Latino male students enroll in post-secondary education, they continue to be disenfranchised, vanished, and often rejected through the higher education pipeline. Research regarding access to education shows that money matters to the success of Latino students. Through a metasynthesis, this practice briefly identifies that there is little to no empirical research conducted that explores how Latino male community college students elicit, engage, and explore financial literacy programs. This paper makes recommendations for post-secondary institutions, practitioners, and policymakers to promote Latino males’ success at community colleges.     

Are Graduating Students Ready for Financial Aspects of Social Work Practice?

ABSTRACT

Graduating students must be prepared with knowledge and skills for the financial aspects of social work practice. This study examines graduating students’ attitudes and perceptions about client finances, as well as their financial knowledge. Internet survey results (n = 116) of BSW and MSW graduating students indicate that respondents (a) perceive a limited function for discussing client financial circumstances in practice, (b) understand the relevance, however, of client finances, (c) are unprepared to address this aspect, and (d) are supportive of integrating this content into required policy and practice courses. Teaching and curricular implications, along with programmatic recommendations, are included.

Financial Aid and College Persistence: Do Student Loans Help or Hurt?

Using data from two freshmen cohorts at a public research university (N = 3730), this study examines the relationship between loan aid and second-year enrollment persistence. Applying a counterfactual analytical framework that relies on propensity score (PS) weighting and matching to address selection bias associated with treatment status, the study estimates that loan aid exerts a significant negative effect on persistence for students from low-income background (i.e., Pell eligible), and those taking up high amounts of loans in order to meet total cost of attendance, including students who exhausted the available amount of subsidized loan aid. However, no significant incremental effect associated with unsubsidized loan aid, net of subsidized loan aid, could be detected. The estimated effect of loan aid on persistence controls for first-year academic experience and takes into account 26 factors related to loan selection and persistence in order to match students with loan aid to a counterfactual case in covariate adjusted regression. Comparison with results from non-matched-sample analysis suggests selection bias may mask the negative effect of loans detected with matched-sample estimation. Validity of covariates determining the loan selection process and criteria for acceptable balance in the matched data are discussed, and implications for future research are addressed.

Who benefits from tuition-free,top-quality universities? Evidence from Brazil

This paper investigates the long-term impact on earnings of attending a tuition-free, top-quality university in Brazil. We identify the causal effect through a sharp discontinuity in an admission process based on test scores. If admitted, low-income students are found to increase their earnings by 26% ten years later. However, admission has a small and insignificant effect on high-income students. The difference between income groups is not explained by educational attainment, program choice, or selection into better-paying jobs. The evidence suggests that most low-income applicants, if not admitted, still graduate from college but with much lower returns to education. High-income applicants who just miss the cutoff, however, can find other opportunities such that earnings trajectories are unchanged. Our results underscore the role of affordable higher education in promoting social mobility.

Fossil Fly from Antarctica

Even if you hate winter, there is at least one nice thing about cold weather and snow: no bugs. Or so you thought.A tiny fly fossil has turned up in Antarctica, about 500 kilometers from the South Pole. Scientists previously thought that the icy continent was never home to this type of fly, which is distantly related to the house flies living today.
