Who is More Free? A Comparison of the Decision-Making of Private and Public School Principals

While an abundance of school choice literature focuses on student achievement outcomes, little has been done to determine the mechanisms involved in producing such outcomes. We present a comparative analysis of private and public school principals using data from the School and Staffing Survey (SASS) 2011-2012. We add to the literature by examining the differences in private and public school principals’ abilities to influence important decisions at their schools. We conclude that private schooling may have a systematic advantage over public schooling since private school leadership exhibits more autonomy in influencing relevant decisions

Event by Event Analysis of High Multiplicity Events Produced in 158 A GeV/c 208 Pb- 208 Pb Collisions

An extensive analysis of individual high multiplicity events produced in 158 A GeV /c 208Pb- 208Pb collisions is carried by adopting different methods to examine the anomalous behavior of these rare events. A method of selecting the events with densely populated narrow regions or spikes out of a given sample of collision events is discussed.Employing this approach two events with large spikes in their eta- and phi- distributions are selected for further analysis. For the sake of comparison, another two events which do not exhibit such spikes are simultaneously analyzed. The findings suggest that the systematic studies of particle density fluctuations in one- and two-dimensional phase-spaces and comparison with those obtained from the studies of correlation free Monte Carlo events, would be useful for identifying the events with large dynamical fluctuations. Formation of clusters or jet like phenomena in multihadronic final states in individual events is also discussed and the experimental findings are compared with the independent particle emission hypothesis by carrying out Monte Carlo simulations

Private Schooling Promotes Political and Economic Freedom? An International Fixed Effects Instrumental Variables Analysis

Additional private schooling within a nation-state may increase citizens’ political and economic freedom through increased educational quality, balanced power relationships, and increased civic engagement. We employ a two-stage-least-squares time and country-level fixed-effects analytical technique to examine how private schooling could affect political rights, civil liberties and economic freedom indices. We also use a new instrumental variable, short-run fluctuations in the demand for schooling, to predict private schooling. We examine 174 different nations across the globe from 1999 to 2014, and find significant evidence to suggest that private schooling leads to enhanced political and economic freedom. In particular, our preferred model finds that a ten percentage point increase in private share of schooling enrollment within a nation, over time, is associated with a 7.4% of a standard deviation increase in the Political Rights Index and an 8% of a standard deviation increase in the Economic Freedom of the World Index

Energy Consumption, Trade and GDP: A Case Study of South Asian Countries

Acute shortage of energy sources in developing countries in general and South Asian countries in particular has shown that energy has become a binding input for any production process. Nowadays operation of heavy machinery and electrical equipment, and transportation of raw material and final products from their place of origination to their destination require heavy consumption of energy in one form or the other. Therefore, energy consumption that was previously ignored in the production function of a firm and an economy is now considered a vital input in production process. It affects GDP directly as by increasing energy consumption; more output can be produced with given stock of capital and labor force in a country. Also uninterrupted availability of energy at reasonable cost improves competiveness of home products in international markets and thus increases exports of home country a great deal. Resulting increase in net exports further adds to the GDP through multiplier effec

The Participant Effects of Private School Vouchers Across the Globe: A Meta-Analytic and Systematic Review

School voucher programs (a.k.a. opportunity scholarships) are scholarship programs - frequently government funded - that pay for students to attend private schools of their choice. Many private school vouchers programs have been initiated around the world with the goal of increasing the academic performance of students. Voucher programs are often viewed as a way to increase achievement and satisfaction for individual students and families, while at the same time creating competitive pressures that encourage other schools in the area to improve. Countries like Chile and India have developed extensive school voucher programs. While many studies have been conducted on school vouchers, a meta-analysis of the international randomized controlled trials (RCTs) evaluating the achievement effects of vouchers has never been conducted. This study is a meta-analytic consolidation of the evidence from all RCTs evaluating the participant test score effects of school vouchers internationally. Our search process turned up 9,443 potential studies, 19 of which ultimately were included. These 19 studies represent 11 different voucher programs. A total of 262 effect sizes are included, with a two-stage consolidation of those estimates yielding a total of 44 drawn from the last year of the studies. We have included only math and reading outcomes as other subjects are rarely reported and are difficult to compare across countries. We also differentiate between English and reading outcomes and present English results as a subcomponent of the reading effects to account for the effect of local language in the international context. Our meta-analysis indicates overall positive and statistically significant achievement effects of school vouchers that vary by subject (math or reading), location (US v. non-US), and funding type (public or private). Generally, the impacts are larger (1) for reading than for math, (2) for programs outside the US relative to those within the US, and (3) for publicly-funded programs relative to privately-funded programs

Use of complementary and alternative medicine in pediatric otolaryngology patients attending a tertiary hospital in the UK

Objective: Little data is available on complementary and alternative medicine (CAM) use in children attending otolaryngology services. We investigated the prevalence and pattern of CAM use among children attending the pediatric otolaryngology department in a tertiary pediatric teaching hospital in Scotland. Design: A cross-sectional survey conducted by administering an anonymous questionnaire to the parents accompanying patients attending the pediatric otolaryngology department. Elective admissions and clinic attendees were included over a 3-month period in 2005/2006. Setting: Academic tertiary care referral centre in North-East Scotland. Patients: Five hundred and fifty-four consecutive patients aged less than 16 years were eligible. The response rate was 59% (n = 327). Main outcome measures: Prevalence of CAM use in children. Secondary measures include types of CAM used, indications for use and communication with family physicians. Results: Based on 327 responses, 93 patients (29%) had ever used CAM, 20% within the last year. Commonly used CAM preparations were cod-liver oil, echinacea, aloe vera, cranberry, primrose oil and herbal vitamin supplements. The popular non-herbal CAM included homeopathy, massage, aromatherapy, chiropractic, yoga and reiki. Nineteen percent used CAM for their admission illness. Sixty-one percent of parents thought that CAM was effective and 65% would recommend it to others. Fifty-one percent of parents stated that the family physician was unaware of CAM use by the child. Conclusions: Despite concerns regarding the efficacy, safety and cost effectiveness of complementary and alternative medicine, its use among the pediatric otolaryngology population is more common than many providers may realize. This has implications for all healthcare workers involved in their care

Comparing and Validating Measures of Character Skills: Findings from a Nationally Representative Sample

Though researchers now are aware of the potential importance of character skills, such as conscientiousness, grit, self-control, and a growth mindset, researchers struggle to find reliable measures of these skills. In this paper, we use data collected from the Understanding America Study, a nationally representative internet panel to study the validity of innovative measures of character skills based on measures of survey effort. We believe surveys themselves can be seen as a behavioral tasks and that respondents provide meaningful information about their character skills by way of the effort they put forward on surveys. In particular, we compare measures of grit, conscientiousness and other personality traits, and growth mindset, based on self-reports, and survey effort measures of character. We study the relationship across each other and their relationship with academic and life outcomes such as income and labor-market outcomes, after controlling for cognitive ability and other relevant demographic characteristics. Our results show that survey effort measures of character skills, in particular measures of careless answering in surveys, show great promise for being good proxy measures of relevant non-cognitive skills
