Traditional versus experimental pathways to university: Educational aspirations among young Swedes with and without an immigrant background

In this paper, we investigate the different ways in which young people with and without an immigrant background, who have in common that they aspire for a higher education, picture their nearest future. We distinguish between two major pathways to a university education: a traditional pathway (direct transition from upper secondary school to university) and an experimental pathway (where university plans are mixed with other plans, such as work and travel). Data come from a school survey of 685 final-year students in 10 upper secondary schools in Malmö, the third biggest metropolitan area in Sweden. We find that it is much more common among youth with an immigrant background to plan for a traditional pathway, compared to youth of Swedish background who instead are more inclined to plan for experimentation. This difference remains when controlling for factors related to school performance and parental socioeconomic background.     

System Estimation of Panel Data Models Under Long-Range Dependence

A general dynamic panel data model is considered that incorporates individual and interactive fixed effects allowing for contemporaneous correlation in model innovations. The model accommodates general stationary or nonstationary long-range dependence through interactive fixed effects and innovations, removing the necessity to perform a priori unit-root or stationarity testing. Moreover, persistence in innovations and interactive fixed effects allows for cointegration; innovations can also have vector-autoregressive dynamics; deterministic trends can be featured. Estimations are performed using conditional-sum-of-squares criteria based on projected series by which latent characteristics are proxied. Resulting estimates are consistent and asymptotically normal at standard parametric rates. A simulation study provides reliability on the estimation method. The method is then applied to the long-run relationship between debt and GDP. Supplementary materials for this article are available online.     

Gender Differences in Sexually Abused Children and Adolescents: A Multicenter Study in Turkey

The purpose of this study was to examine gender-based differences in abuse-related characteristics and post-abuse psychiatric disorders among sexually abused children and adolescents. The researchers retrospectively examined files, judicial reports, and social examination reports of 1,250 sexually abused youth cases. Results showed that boys were more often victimized by penetration, force, and physical violence. Incidence of sexual abuse by family members, familiar persons, and multiple persons was higher among girls. In addition, a higher rate of major depressive disorder as well as alcohol consumption and cigarette smoking were found in sexually abused girls. No difference was observed between boys and girls in terms of post-traumatic stress disorder, conduct disorder, and other mental disorders. Intellectual disability was more frequent in boys.     

The Changes of Cost of Children for Turkey by Using Income-Dependent Equivalence Scales

This study aims to estimate the cost of children in Turkey by using equivalence scale approach for different income levels and suggests a new commodity composition for Muslim countries. We used 2003, 2007 and 2014 household budget survey micro data set. According to the calculations of Engel equivalence scales, the cost of children decreases from 2003 to 2014 in Turkey. Since the data of 2007 is determined as reasonable consumption behaviours of Turkish households, the inequality and poverty researches can use equivalence scales calculations of 2007. If anyone wants to estimate Rothbarth equivalence scales for a Muslim country, using of “adult goods” which is defined as “expenditures of alcohol, tobacco, adult cloths and adult shoes” in literature would not be suitable. This study suggests “a new commodity group” which is “furnishing and communication”. The Engel model estimations are significant for households who are at the middle and high income level whereas the results of Rothbarth model estimations are found as significant for low and middle income groups. As a result, we recommend to use equivalence scales estimations’ results for middle income groups in the inequality and poverty researches, since this group is free from irregular expenditure behaviors and gives significant estimations for both models.     

Optimal progressive group censoring scheme under cost considerations for pareto distribution

In this article, optimal design under the restriction of pre-determined budget of experiment is developed for the Pareto distribution when the life test is progressively group censored. We use the maximum-likelihood method to obtain the point estimator of the Pareto parameter. We propose two approaches to decide the number of test units, the number of inspections, and the length of inspection interval under limited budget such that the asymptotic variance of estimator of Pareto parameter is minimum. A numerical example is given to illustrate the proposed method. Some sensitivity analysis is also studied.     

Outsourcing vs. in-house production: a comparison of supply chain contracts with effort dependent demand

We analyze the effort and pricing decisions in a two facility supply chain in which one of the parties can exert costly effort to increase demand. We consider an outsourcing model in which the supplier makes the effort decision and an in-house production model in which the manufacturer decides on the effort level and we compare these two models with each other. We analyze and compare several contracts for decentralized supply chain models and we aim to find which contracts are best to use in different cases. We find the optimal contract parameters in each case and perform extensive computational testing to compare the efficiencies of these contracts. We also analyze the effect of the powers of the parties in the system and the effect of system parameters on the performances of the contracts and on the optimal values of the model variables such as price, effort and demand.     

Increasing the Power of the Test Through Pre-Test – A Robust Method

Robust test procedures are developed for testing the intercept of a simple regression model when the slope is (i) completely unspecified, (ii) specified to a fixed value, or (iii) suspected to be a fixed value. Defining (i) unrestricted (UT), (ii) restricted (RT), and (iii) pre-test test (PTT) functions for the intercept parameter under the three choices of the slope, tests are formulated using the M-estimation methodology. The asymptotic distributions of the test statistics and their asymptotic power functions are derived. The analytical and graphical comparisons of the tests reveal that the PTT achieves a reasonable dominance over the other tests.
