Some university students are more equal than others: Efficiency evidence from England

This paper estimates the efficiency of students in English universities using Data Envelopment Analysis (DEA) and a new dataset which is able to capture the behaviour of university students. Two output variables are specified: the classification of a university degree, and student satisfaction. Three input variables are specified: teaching hours, private study and entry qualifications. The results reveal that university students differ in terms of the efficiency with which they use inputs in generating good degrees and satisfaction. Students in some post-92 universities may be more efficient than students in some pre-92 universities.Data Envelopment Analysis; Efficiency; Education Economics; Universities.

An Exploration of the Experience of Interaction between the Police and Juvenile Offenders in Taiwan

By developing Foucault’s concepts of power, this paper aims to explore the interaction experience between Taiwanese police and juvenile offenders from a critical perspective. From macro analysis of social discourse to micro daily practice, the study objectives are to examine whether the police act as a mechanism of discourse formation for juvenile offenders, to articulate how the strategies and techniques are enforced or strengthened and to scrutinise how juveniles are disciplined and resisted. The findings reveal that the dual-oppositional discourses are constructed by defining juveniles as either ‘normal’ or ‘deviant’. Through the discipline and inspection techniques used by police, juveniles are forced to fit the image of the ‘normal juvenile’. To maintain a sense of their autonomous self, juveniles choose to resist these stereotypes. The struggle contributes to the criminal discourse reproduction, pushing juveniles into categories of criminal offenders. It is hoped that this paper can offer a framework for analysing and discussing policy in criminology and criminal justice

Interest Rate Rules, Target Policies, and Endogenous Economic Growth in an Open Economy

This paper sets up an endogenous growth model of an open economy in which the monetary authority implements a gradualist interest-rate rule with targets for inflation and economic growth. We show that, under a passive rule, a monetary equilibrium exists and is unique; moreover, the equilibrium is locally determinate. Under an active rule, the open economy either generates multiple equilibria or does not have any equilibrium. If equilibria exist, the high-growth equilibrium is locally determinate while the low-growth equilibrium is a source. Besides these, the stabilization and growth effects of alternative target policies are also explored in this study.Nominal interest rate rules, gradualism, endogenous economic growth

A study of the total chromatic number of equibipartite graphs

AbstractThe total chromatic number χt(G) of a graph G is the least number of colors needed to color the vertices and edges of G so that no adjacent vertices or edges receive the same color, no incident edges receive the same color as either of the vertices it is incident with. In this paper, we obtain some results of the total chromatic number of the equibipartite graphs of order 2n with maximum degree n − 1. As a part of our results, we disprove the biconformability conjecture

Effects of Hydrogen on the Optical and Electrical Characteristics of the Sputter-Deposited Al2O3-Doped ZnO Thin Films

In this study, AZO thin films were deposited on glass by using a 98 mol% ZnO + 1 mol% Al2O3 (AZO, Zn : Al = 98 : 2) ceramic target and a r.f. magnetron sputtering system. At first, the effects of different H2 flow rates (H2/(H2 + Ar) = 0%~9.09%, abbreviated as H2-deposited AZO thin films, deposition temperature was 200°C) added during the deposition process on the physical and electrical properties of AZO thin films were investigated. The optical transmittance at 400 nm~700 nm is more than 80% for all AZO thin films regardless of H2 flow rate and the transparency ratio decreased as the H2 flow rate increased. The Burstein-Moss shift effect was used to prove that the defects of AZO thin films decreased with increasing H2 flow rate. Also, the 2% H2-deposited AZO thin films were also treated by the H2 plasma at room temperature for 60 min (plasma-treated AZO thin films). The value variations in the optical band gap (Eg) values of the H2-deposited and plasma-treated AZO thin films were evaluated from the plots of αhν2=c(hν−Eg), and the Eg values increased with increasing H2 flow rate. The Eg values also increased as the H2-plasma process was used to treat on the H2-deposited Al2O3-doped ZnO (AZO) thin films
