As the wave of liberalization and deregulation have accelerated to relieve rigid controls over airline routes, capacity, and fare setting regimes, Low Cost Carriers (LCCs) have emerged especially in local aviation markets since the 1970s.

This paper has studied the effects of LCC's entry into the domestic aviation market which was pre-occupied by two major carriers, Korean Air (KAL) and Asiana Airlines. Through a simple model describing two situations, prior and post to LCC's entry, we analyzed changes and trends of each airline's output and profit based on the Cournot and two-stage Stackelberg game equilibrium.

In summary, our conclusion consists of five points: (1) Even though JIN Air's entry reduced KAL's respective output and profit, the more JIN Air produces, the higher the joint-profit of KAL and JIN Air is, (2) From the joint-profit aspect, increasing KAL's output to a level than JIN Air's is more profitable on the Gimpo-Jeju route, on the other hand, increasing JIN Air's output higher than KAL's is more profitable on the Jeju-Busan route, (3) Even though JIN Air's entry increase Asiana Airline's output, the more JIN Air produces, the less Asiana Airlines's profit is, (4) Total output in markets as well as total profits of firms will increase under certain conditions, (5) KAL and JIN Air tend to get caught in an unresolved conflict on level of LCC cost.

Numerical simulations have been used to analyse steady-state natural convection of non-Newtonian power-law fluids in a square cross-sectioned cylindrical annular cavity for differentially heated vertical walls for a range of different values of nominal Rayleigh number, nominal Prandtl number and power-law exponent (i.e. 103 < Ra < 106, 102 < Pr < 104 and 0.6 < n < 1.8). The paper aims to discuss these issues.

Analysis is carried out using finite-volume based numerical simulations.

Under the assumption of axisymmetry, it has been shown that the mean Nusselt number on the inner periphery Nu _i increases with decreasing (increasing) power-law exponent (nominal Rayleigh number) due to strengthening of thermal advection. However, Nu _i is observed to be essentially independent of nominal Prandtl number. It has been demonstrated that Nu _i decreases with increasing internal cylinder radius normalised by its height r _i /L before asymptotically approaching the mean Nusselt number for a two-dimensional square enclosure in the limit r _i /L→infinity. By contrast, the mean Nusselt number normalised by the corresponding Nusselt number for pure conductive transport (i.e. Nu _i /Nu _cond ) increases with increasing r _i /L.

A correlation for Nu _i has been proposed based on scaling arguments, which satisfactorily captures the mean Nusselt number obtained from the steady-state axisymmetric simulations.

Many students in the United States struggle to achieve proficiency in writing. Writing is an important skill to develop, as it is a way for students to communicate what they know and integrate knowledge and critical thinking skills. A lack of writing proficiency can have a significant impact on academic performance in secondary school and on postsecondary outcomes. Improving writing instruction requires theoretically sound, scientifically validated teaching practices, including assessments and instructional methods. It also requires that teachers are well prepared to implement such practices, including using assessment data to tailor instructional methods to meet the needs of students who experience significant writing difficulties. The purpose of this chapter is to provide an overview of advances in research and practice related to validated teaching practices designed to improve the writing outcomes of students with intensive needs, and to describe an innovative way to prepare and support teachers to implement such practices.

Doctors play a central role in leading improvements to healthcare systems. Leadership knowledge and skills are not inherent, however, and need to be learned. General frameworks for medical leadership guide curriculum development in this area. Explicit discipline-linked competency sets and programmes provide context for learning and likely enhance specialty trainees’ capability for leadership at all levels. The aim of this review was to summarise the scholarly literature available around medical specialty-specific competency-based curricula for leadership in the post-graduate training space.

A systematic literature search method was applied using the Medline, EMBASE and ERIC (education) online databases. Documents were reviewed for a complete match to the research question. Partial matches to the study topic were noted for comparison.

In this study, 39 articles were retrieved in full text for detailed examination, of which 32 did not comply with the full inclusion criteria. Seven articles defining discipline-linked competencies/curricula specific to medical leadership training were identified. These related to the areas of emergency medicine, general practice, maternal and child health, obstetrics and gynaecology, pathology, radiology and radiation oncology. Leadership interventions were critiqued in relation to key features of their design, development and content, with reference to modern leadership concepts.

There is limited discipline-specific guidance for the learning and teaching of leadership within medical specialty training programmes. The competency sets identified through this review may aid the development of learning interventions and tools for other medical disciplines.

The findings of this study provide a baseline for the further development, implementation and evaluation work required to embed leadership learning across all medical specialty training programmes.

Discrimination is defined as negative or harmful behavior toward a person because of his or her membership in a particular group (see Jones, 1997). Unfortunately, experiences with discrimination due to racial group membership appear to be a normal part of development for African American youth. Discrimination experiences occur within a variety of social contexts, including school, peer, and community contexts, and with increasing frequency as youth move across the adolescent years (Fisher, Wallace, & Fenton, 2000; Seaton et al., 2008). Recent research with a nationally representative sample of African American 13–17-year olds revealed that 87% had experienced at least one racially discriminatory event during the preceding year (Seaton et al., 2008). Most of the research on the consequences of youths’ encounters with racial discrimination has focused on mental health outcomes (Cooper, McLoyd, Wood, & Hardaway, 2008), with surprisingly little work examining whether and through what mechanisms discrimination affects achievement motivation.

These notes on Sir Walter Scott by John Galt, here published for the first time, have been transcribed by Dr Hamilton B. Timothy, Associate Professor in the Department of Classical Studies and Galt Scholar at the University of Western Ontario, from a manuscript among the material given him by Henry Gordon Harvey Smith, Q.C., a great‐grandson of John Galt, and his sister, Mrs Muriel Harvey Turner, of Winnipeg. John Galt's youngest son, Alexander, with whom Galt's widow made her home after the novelist's death in 1839, became the Hon. Sir Alexander Galt and Canada's first Federal Finance Minister; from him John Galt's library and miscellaneous papers passed to his youngest daughter, Annie Prince Galt, who married Dr W. Harvey Smith, a distinguished opthalmologist. (In 1930 he had the rare honour of holding at the same time presidency of both the British Medical Association and the Canadian.) His carefully augmented collection of Galt family papers, inherited by his son and daughter, has now been passed to Dr Timothy for use in connexion with his study, The Galts: a Canadian Odyssey. At the same time the family collection of John Galt's writings—in sixty‐eight volumes, many from the novelist's own library—was presented to the library of the University of Western Ontario. For permission to print these interesting notes we are indebted to Mr Harvey Smith and Mrs Turner. The annotations initialled C are by Dr Robert Hay Carnie of the University of Calgary.
