Abstract

Purpose

This study aims to analyse the conditional volatility of the Vietnam Index (Ho Chi Minh City) and the Hanoi Exchange Index (Hanoi) with a specific focus on their application to risk management tools such as Expected Shortfall (ES).

Design/methodology/approach

First, the author tests both indices for long memory in their returns and squared returns. Second, the author applies several generalised autoregressive conditional heteroskedasticity (GARCH) models to account for asymmetry and long memory effects in conditional volatility. Finally, the author back tests the GARCH models’ forecasts for Value-at-Risk (VaR) and ES.

Findings

The author does not find long memory in returns, but does find long memory in the squared returns. The results suggest differences in both indices for the asymmetric impact of negative and positive news on volatility and the persistence of shocks (long memory). Long memory models perform best when estimating risk measures for both series.

Practical implications

Short-time horizons to estimate the variance should be avoided. A combination of long memory GARCH models with skewed Student’s t-distribution is recommended to forecast VaR and ES.

Originality/value

Up to now, no analysis has examined asymmetry and long memory effects jointly. Moreover, studies on Vietnamese stock market volatility do not take ES into consideration. This study attempts to overcome this gap. The author contributes by offering more insight into the Vietnamese stock market properties and shows the necessity of considering ES in risk management. The findings of this study are important to domestic and foreign practitioners, particularly for risk management, as well as banks and researchers investigating international markets.

Abstract

We have witnessed, over the past century, an evolution in the manner in which students with disabilities are educated. Indeed, the quality of education students with special needs receive, in many ways, may be more aptly termed a revolution – from a legal and pedagogical perspective. The tremendous strides special education has made during this period of time has resulted in the current situation in which students with special needs are placed in the least restrictive environment, which often is an inclusive classroom in which general education and special education teachers work together in a collaborative, co-teaching environment. This chapter traces the events, legislation, and court cases that provide the historical context for this situation. In addition, models and essential components of co-teaching are examined, as well as the roles and requisite skills of general education and special education co-teachers. Of critical importance, in the success of co-teaching, is the need for special education and general education teachers to approach the curriculum planning and instructional processes in a collaborative and cooperative manner in order to achieve optimum results from the resulting co-teaching partnership. Finally, the assessment of special education and general education co-teaching efficacy is discussed, specifically through the use of three assessment rubrics used to evaluate co-teaching, co-planning, and co-assessment.

Abstract

Purpose

The purpose of this chapter is to explore the Occupational Course of Study (OCS) program through blended learning courses offered through the North Carolina Virtual Public School. In this program, students take classes online with a virtual content area teacher and meet in a face-to-face setting with a certified special education teacher.

Methodology/approach

This chapter offers a practical exploration of the OCS program. Its intention is to offer insight into the perspectives of virtual teachers and face-to-face teachers and provide an understanding of how this type of blended learning has the potential to deliver high quality academic coursework targeted to meet individual learning needs.

Findings

This blended environment format is a viable method for helping highly qualified content area teachers and teachers with disabilities work together to meet the individual learning needs of students with disabilities.

Research implications

The OCS program is able to support large numbers of students who need transition services. Evaluation on this program reveals that collaboration between various educational professionals supports learning outcomes for students.

Originality/value

Many K12 districts offer alternative diplomas for students with exceptionalities, with a goal of preparing students for their transition to postsecondary employment and independent living. This chapter offers a practical description of this program for the benefit of other systems that may want to consider this model.

Abstract

In the United States, students with disabilities have moved from learning in a segregated environment to being included in the general education classroom. Legislative mandates have encouraged this shift to occur in public schools in order to equal the playing field for students with disabilities. Both general and special education students with learning disabilities (LD) have been affected from inclusion. This chapter describes the legal, historical, psychological, and instructional concepts shaping the way students with LD are educated today.

Abstract

This chapter describes the influences that are fundamental to facilitating a system of support for inclusive education for students with low-incidence disabilities. Some of the major factors are values and beliefs, rights, relationships and a sense of belonging, policy, and effective practices (Smith, 2006; Walther-Thomas, Korinek, McLaughlin, & Williams, 2000). Within each of the features, collaboration is inherent and essential. A summary of literature on each feature is provided with examples to support the importance for students with low-incidence disabilities. The effective practices of Universal Design for Learning (UDL), co-teaching, peer supports, and school-based teams are highlighted. In order to move forward, educators and administrators need to take responsibility for all children. Effective leadership models are characterized by collaborative efforts that foster a shared responsibility of the team, emphasize thoughtful planning, and identify and allocate the necessary resources and supports.

Abstract

The standards movement, while new in the current NCLB iteration, has been a part of education for almost the last half century (Popham, 2001; Sirotnik, 2004). According to several researchers (e.g., DiPaola & Walther-Thomas, 2003; Fullan, 2001; Lashley & Boscardin, 2003; Marsh, 2000; Villa & Thousand, 2000), there have been significant changes in the roles that school leaders must fulfill to implement a standards-based educational accountability system. The requirements of NCLB will not be a “passing fad” and so will affect the manner in which special education administrators conduct their work (Hochschild, 2003). As it stands, districts and schools are viewed as an amalgam of complex relationships (Harry, Sturges, & Klinger, 2005) that come together as learning communities to meet accountability targets for all students. The requirements for building a learning community involve the skills of collaboration and empowerment of others. Apparently, developing productive partnerships will exceed the previously defined narrow interpretation of collaboration with families and other professionals (Crockett, 2002). Standards-based accountability practices which disaggregate data based on specific subgroups, one of which is students with disabilities, are a result of the concern that exclusion of students from testing distorts the efficacy of educational reform efforts (Heubert & Hauser, 1999; McDonnell, McLaughlin, & Morison, 1997; Schulte & Villwock, 2004). However, concerns have also been raised regarding the validity of conclusions drawn from large-scale accountability data (Schulte & Villwock, 2004; Ysseldyke & Bielinski, 2002). Hargreaves (2003) concluded that “the rightful pursuit of higher standards has generated into a counter productive obsession with soulless standardization” (p. 82).

Abstract

Thirty-two qualitative research reports on co-teaching in inclusive classrooms, identified through a comprehensive literature search, are reviewed. Studies have included significant diversity in grade level, geographical location, setting, and took place in three different countries. Overall, teachers and administrators reported a high degree of satisfaction with co-teaching. However, a number of needs were also addressed, including administrative support, appropriate caseloads, planning time, student skill level, and co-teacher compatibility. Implications for research and practice are discussed.

Abstract

Although less than 1% of violent student deaths take place in schools, incidents such as the shootings that took place at Columbine High School in 1999 have fueled a general impression that schools are unsafe (Hall & Marsh, 2003; Osher & Quinn, 2003). Media reports about bomb threats, bullying episodes, and disruptive classroom behaviors have further contributed to a widespread belief that schools are not as safe as they should be (Osher & Quinn, 2003; Chicago Tribune Online Edition, 2006).
