Nigerian Stock Index: A Search For Optimal Garch Model Using High Frequency Data, Olaoluwa Simon Yaya
CBN Journal of Applied Statistics (JAS)
This paper attempts to fit the best Generalized Autoregressive Conditional Heteroscedastic (GARCH) model for All Share Index (ASI) of Nigerian Stock Exchange (NSE) returns. A search is made on various GARCH variants specified on the assumptions of stationarity and asymmetry. Fractionally integrated types are also considered to capture the possibility of return series having property of long range dependency. The parameter estimations are carried out on the assumptions of normality and non-normality of GARCH innovations, with models and forecasts evaluated using information criteria and loss functions respectively. Under normality assumption, Hyperbolic GARCH (HYGARCH(1,d,1)) model is selected and Integrated GARCH (IGARCH(1,1)) …

A Markov Decision Process Approach To Optimal Control Of A Multi-Level Hierarchical Manpower System, Akaninyene U. Udom
CBN Journal of Applied Statistics (JAS)
A recurrent problem in manpower control is how to attain the desired structural configuration in an optimal way, since it is possible to reach a desired structural configuration using different control inputs. The major aim of this paper is to develop a Markov Decision Process for optimal control of a Multi-level Hierarchical Manpower System (MHMS) by promotion and interdepartmental transfers. This is examined under control by intervention and contraction cost Markov Decision Process.

Me And Goldilocks...Searching For What Is “Just Right” In Trauma Research: An Autoethnography, Rosemary C. Reilly
The Qualitative Report
This is a reflexive account of the tensions and dilemmas emerging from my experience as a woman qualitative researcher researching trauma and tragedy in communities. Framed as an autoethnography, using my conflictual childhood feelings about Goldilocks as an overarching metaphor, I will weave fairy tale and experience into an examination of the impact I can have on individuals, families, and communities in the course in pursuing research. I will attempt to highlight the edges of research culture and ethical conduct, the politics of trespass and the rights of individuals and communities while trying to discover what is “just right.”

A Journey Of Pregnancy Loss: From Positivism To Autoethnography, Julie Sell-Smith, William D. Lax
The Qualitative Report
When a dissertation research project exploring the impact of mind - body practices on symptoms of depression and anxiety in pregnant women with a history of miscarriage failed to yield statistically significant results, I struggled with how to demonstrate that I had gleaned knowledge from this project of nearly 3 years. When a series of parallel pregnancy losses occurred in my own life, I realized that I am heavily situated within the context of my research and need to consider my data in a different sense; one that acknowledges my own self within this process while attempting to capture the …

Brand Equity Planning With Structuralist Rhetorical Semiotics: A Conceptual Framework, George Rossolatos
The Qualitative Report
This paper furnishes a structuralist rhetorical semiotic conceptual framework for brand equity planning. The main source of brand equity that is employed for exemplification purposes is the advertising filmic text. The conceptual framework assumes as its general blueprint Greimas’s generativist model of the trajectory of signification. Structuralist operations and operations of rhetorical transformation are posited as the basis for the generation of superior brand associations. The conceptual model put forward challenges the Greimasian assumption that a depth semantic structure is reducible to a binarist rationale, while adopting a connectionist approach in the form of associative networks. At the same time, …

Exploring Education Students’ Reflexivity Through The Arts And Sharing My “Bricolage” Dilemmas, Janet C. Richards
The Qualitative Report
As part of course requirements, 16 education students in a master’s cohort tutored groups of elementary children (the same groups throughout the semester) in an after - school writing program that emphasized an ethos of care. The education students had never taught children and consequently had difficulties reflecting about their lessons through weekly e - mail communication. As the course instructor I had a hunch innovative artistic processes might unleash and heighten the education students’ abilities as reflective practitioners . Therefore, I asked them to explore their pedagogy through the arts. Concurrently, I engaged in arts - based educational research …

Calibrating The Human Instrument: Understanding The Interviewing Experience Of Novice Qualitative Researchers, Margarita S. Peredaryenko, Steven Eric Krauss
The Qualitative Report
Scientific instruments often undergo calibration to ensure that they will produce results that meet or exceed defined criteria within a specified degree of confidence. Such calibration almost always refers to mechanical instruments, those used primarily in the physical sciences. Rarely is the notion of calibration used in relation to the social and human sciences, especially in the context of qualitative research where the human being is the main research instrument. The focus of this study was to explore the experiences of novice human instruments undergoing a process similar to that of calibration. In doing so, we studied how novice qualitative …

Alive In The Reading: Nayaran And Chekhov, Laurie Ecke
The Qualitative Report
Kirin Nayaran's Alive in the Writing: Crafting Ethnography in the Company of Chekhov is a five - section book about finding "company amid the often isolating and difficult aspects of writing" (p. xiii). As an English Literature major, I recall the basic tenets of story - writing: plot, setting, and characterization. Narayan's chapters offer a kinder entry. "Story and Theory" invoke Anton Chekhov as an ethnographic companion offering expertise about the essentials of writing a good story. "Place," "Person," and "Voice" take the innocent writer further in to the power of writing, until "Self" provides a denouement of sorts, when …
