On Leverage In A Stochastic Volatility Model, Jun Yu

Research Collection School Of Economics

This paper is concerned with specification for modelling financial leverage effect in the context of stochastic volatility (SV) models. Two alternative specifications co-exist in the literature. One is the Euler approximation to the well known continuous time SV model with leverage effect and the other is the discrete time SV model of Jacquier, Polson and Rossi (2004, Journal of Econometrics, forthcoming). Using a Gaussian nonlinear state space form with uncorrelated measurement and transition errors, I show that it is easy to interpret the leverage effect in the conventional model whereas it is not clear how to obtain the leverage effect …

Bio-Optical Properties Of The Arctic Waters: Empirical And Theoretical Observations, Jian Wang

OES Theses and Dissertations

Bio-optical observations were made during August 2000 in the Beaufort and Chukchi Seas. Chlorophyll a concentration (Chl) ranged from 0.068 to 18.51 mg chl m⁻³. Both total particulate and phytoplankton absorption at 443 nm were closely correlated with chlorophyll concentration. There is no strong correlation between chlorophyll concentration and absorption by soluble materials or nonpigmented particulates. Absorption, scattering, and attenuation all show strong first-order spectral relationships. Two semianalytical remote sensing reflectance models were evaluated and validated using bio-optical data collected in this region. Both models were proficient at retrieving chlorophyll concentration, phytoplankton absorption coefficients, and particulate backscattering coefficients. …

Converting Low-Level Mixed Waste Into Transuranic Waste For Geologic Disposal At Wipp: A Cost Analysis, Helen R. Neill, Robert H. Neill

Public Policy and Leadership Faculty Research

The Department of Energy (DOE) has approximately 43,000 cubic meters of mixed-low-level waste (MLLW) with alpha emitting concentrations of 10 to 100 nanocuries per gram (nCi/g) generated from the nations defense programs requiring radioactive waste disposal [1]. DOE has decided to commingle MLLW containers with transuranic (TRU) waste containers in larger containers such that the average concentration in the larger container would qualify as TRU waste for deep geologic disposal at the Waste Isolation Pilot Plant (WIPP). Since Congress has exempted the WIPP mixed TRU waste from the Resource Conservation and Recovery Act (RCRA) [2] requirement to treat the waste …

Fish Stock And Fishery Enhancement In Western Australia. A Summary Report., Department Of Fisheries

Fisheries Management Papers

This summary paper provides an overview of the key proposals set out in the full policy discussion paper, Fisheries Management Paper No 175. It does not discuss the theoretical background for the framework presented and therefore readers interested in such discussion are directed to Fisheries Management Paper No 175.

Both papers have been prepared to encourage public involvement in the development of policy for stock enhancement within Western Australian waters. Stock enhancement can involve an existing fishery or creation of a new fishery through the translocation of fish. It affects both public and private waters.

Investigation Of Geobase Implementation Issues: Case Study Of Information Resource Management, Mario L. Oliver

Theses and Dissertations

Billions of dollars have been wasted on failed information system (IS) projects over the last decade in the private and public sectors. More specifically, the tri-service environment of the U.S. military has not implemented a single successful geospatial IS (GIS). The lack of a service-wide insertion process for GIS was cited as the most significant cause for military GIS failures. GeoBase represents the USAF's most recent GIS implementation. The GeoBase program focuses on Information Resource Management (IRM) and cultural issues. The GeoBase Sustainment Model (GSM), anecdotally developed by GeoBase leadership to reflect implementation issues and the IRM practices of the …

No News Is Bad News: Characteristics Of Adolescents Who Provide Neither Parental Consent Nor Refusal For Participation In School-Based Survey Research, C. Anderson Johnson, Jennifer B. Unger, Peggy E. Gallaher, Paula Palmer, Lourdes Baezconde-Garbanati, Dennis R. Trinidad, Steven Cen

CGU Faculty Publications and Research

Schools offer a convenient setting for research on adolescents.However, obtaining active written parental consent is difficult. In a 6th-grade smoking study, students were recruited with two consent procedures: active consent (parents must provide written consent for their children to participate) and implied consent (children may participate unless their parents provide written refusal). Of 4,427 invited students, 3,358 (76%) provided active parental consent, 420 (9%) provided active parental refusal, and 649 (15%) provided implied consent (parental nonresponse). The implied consent procedure recruited more boys, African Americans, students with poor grades, and smokers. This dual-consent procedure is useful for collecting some limited …

Image Compression And Its Effect On Data, Khaled S. Alkharabsheh

Theses, Dissertations and Capstones

This thesis is intended to define and study different image compression techniques, software programs, image formats (from early ones such as “GIF” to most recent ones such as “JPEG 2000”), compression effect on compressed data (compressed images), and its effectiveness and usefulness in reducing the file size and its transmission time, as a result.

In many GeoBioPhysical applications, some information inside any image may be the keys to solve different kinds of problems and classify features. This kind of data and information has to be handled with care; i.e. it’s not allowed to be lost during the compression process. On …

A Mixed-Method Investigation Of The Solo In A Wilderness Experience Program, Andrew J. Bobilya, Kenneth R. Kalisch, Leo H. Mcavoy, Jeffrey A. Jacobs

Research in Outdoor Education

The purpose of this study was to investigate the participants' perceptions of an organized solo within a wilderness experience program and the influence that the participants themselves and the environment have on their perception. The literature suggests that many factors influence one's ability to experience wilderness solitude and to engage in meaningful reflection that may lead to personal growth (Daniel, 2003; Fredrickson & Anderson, 1999; Hammitt,1982; Hendee & Brown, 1988; Koch, 1994; McIntosh, 1989; Norris, 2001; Richley, 1992; Stringer & McAvoy, 1992). Two of these factors can be categorized as the participant(s) and the environment; both are considered key program …

The Impacts Of Satellite Phone Technology On A North Carolina Outward Bound School Experience, Tommy Holden

Research in Outdoor Education

Over the last 20 years, adventure-based programs have flourished resulting in additional use of wilderness areas. One of the many factors contributing to this growth is the development and use of new technologies. "New technology ... has allowed backcountry users to greatly expand their reach ... " (McKay, 2000, pg. 150). Adventure-based programs are no exception to the use of this technology. For example, many programs now carry cellular or satellite phones into the backcountry, required as part of their risk management plans. However, the effects of this communications technology on the participants' wilderness and adventure-based experience have yet to …

Environmental Sensitivity And Experience Preferences In Outdoor Recreation Participation, Tinelle Bustam, Anderson B. Young, Sharon L. Todd

Research in Outdoor Education

In the past 30 years, a number of researchers have attempted to understand what makes people care about the environment or what underlies "environmental sensitivity." Most of this research is rooted in the theory that environmental sensitivity (ES) is the first step in a developmental process that.leads persons in the direction of feeling what Chawla (1998) calls "ownership" and "empowerment" (p. 11) regarding protection of the environment· Some early researchers focused on.individuals' self-claimed influences on environmental sensitivity based on "significant life experiences" (Peterson, 1982; Tanner, 1980}; while others attempted to find an association between outdoor participation and environmental concern (Dunlap …

The Relationship Between Summer Camp Employment And Emotional Intelligence, Jeffrey A. Jacobs, Leo H. Mcavoy, Andrew J. Bobilya

Research in Outdoor Education

Camping professionals have long claimed that summer camp employment provides camp staff with a number of benefits. The summer camp staff experience has been shown to have a positive effect on the staff members' personal, social and emotional growth (Bialeschki, Henderson, & Dahowski, 1998; DeGraff & Glover, 2002). Yet, some influentia. others such as parents and human resources professionals have questioned the wisdom of a college student spending a summer of "fun in the sun", working at a summer camp for low pay.

The concept of emotional intelligence has been recently gaining favor in the human resource management arena, and …

The Effects Of Intentional Recreation Programming On Internalization Of Type 1 Diabetes Management Among Adolescents, Eddie Hill, Jim Sibthorp

Research in Outdoor Education

This study, with the help of the Utah Association of Diabetes Educators, attempted to determine the effectiveness of using self-determination theory (SDT) at an adolescent diabetes camp to increase internalization of diabetes management. Existing evidence indicates that adolescents manage less than 20% of their diabetes, far less than needed (Anderson, 1985). Failure to manage and internalize behavior for regulating glycemic levels can lead to a number of very significant problems (Bryden, Peveler, Stein, Neil, Mayou & Dunger, 2001). This limited internalized behavior·may be explained by SDT. Self determination theory provides a basis for creating an autonomy supportive. environment while fostering …

Understanding The Role Of Spirituality And Theology In Outdoor Environmental Education: A Mixed-Method Characterization Of 12 Christian And Jewish Outdoor Programs, Gregory E. Hitzhusen

Research in Outdoor Education

This paper examines the role of spirituality in some explicitly religious outdoor environmental programs. As fitting for such a complex research topic that is not yet well understood, a mostly descriptive and narrative mixed methodology is used to characterize a set of Christian and Jewish outdoor programs that demonstrate an original combination of outdoor and environmental education within their spiritual context. Such analysis can help broaden the base of outdoor education spirituality research, can increase awareness of traditionally religious perspectives operative in outdoor education and environmental education and can suggest models for. outdoor educators within religious traditions. Finally, it can …

Using Experience Sampling Method To Understand The Environment For Reflective Learning, Taito Okamura

Research in Outdoor Education

The purpose of this study was to identify the appropriate learning environment for reflective learning during a five-day wilderness adventure program by measuring participant's perception of "yutori", which was a similar concept to "leisure as a state of mind" using Experience Sampling Method (ESM). This study was conducted under the assumption that a learning environment where participants· perceive "yutori', is appropriate for spontaneous reflective learning, based on Nishino's studies that positive mood appears when perceiving "yutori" (Nishino & Chinen, 1998) and that perception of "yutori" relates to intrinsic motivation and freedom of choice for the behavior (Nishino, 1999).

Focusing In: Using Photo Elicitation To Explore The Meanings Of Outdoor Experiences, T. A. Loeffler
