Network Function Virtualization Technology Adoption Strategies
No full textNetwork function virtualization (NFV) is a novel system adopted by service providers and organizations, which has become a critical organizational success factor. Chief information officers (CIOs) aim to adopt NFV to consolidate and optimize network processes unavailable in conventional methods. Grounded in the diffusion of innovation theory (DOI), the purpose of this multiple case research study was to explore strategies chief information officers utilized to adopt NFV technology. Participants include two CIOs, one chief security information officer (CSIO), one chief technical officer (CTO), and two senior information technology (IT) executives. Data were collected through semi-structured telephone interviews and eight organizational documents. Through thematic analysis, four significant themes became apparent: organizational awareness, no hindrances to NFV technology adoption, documentation and implementation plan, and operational costs and efficiency. A key recommendation is for CIOs, CSIOs, CTOs, and senior IT managers to adopt the capability to document globally accepted processes and procedures for seamless adoption of NFV technology. The implications for positive social change include the potential to reduce energy consumption, preserving natural resources, and reducing environmental pollution due to the emission of dangerous gases that cause environmental degradation

An Ethnographic Reading of Nigerian Migrant Autobiographical Poetry in English
No full textLiterature, poetry in particular, has generally been marginalised in discourses on social history. While literature is seen by many critics, particularly social scientists and historians, as essentially fictitious and literary autobiographies as self-aggrandising, poetry, as a sub-genre of literature, is scarcely discussed as autobiography. Very few works have considered the possibilities of Nigerian poetry as auto/biography. Using ethnography of communication and postcolonial theoretical perspectives, this study, examines two purposively selected collections of Nigerian migrant poetry to establish their qualities as autobiographies. It also discusses the ethnographic qualities of Nigerian migrant autobiographical poetry and underscores its quality as not a mere self-aggrandising narration but a blend of self and the culture/society within which the self-narration is constructed.Keywords: Nigerian migrant poetry, ethnoautobiography, social history, self-writing, cultural constructio
Biblical Names in Selected Plays of Wole Soyinka: A lexico-semantic Study
No full textThis study interrogates the use of biblical names as charactonyms in selected plays of Wole Soyinka, the first Nobel laureate in Africa, with the aim of unearthing their morphological process and sociolinguistic imports in relation to the Holy Bible. The primary data from which extracts were made to illustrate the discussion were four drama texts: The Strong Breed (1963), The Road (1965), Death and the King’s Horseman (1975), King Baabu (2002)- all tragedies, by the same author. The theoretical frameworks adopted were Yule’s (1985) morphological taxonomy and Said’s (1978) postcolonialism. Ten names inundated with biblical elements were purposively selected across-the-board and analysed using the theoretical frameworks. Findings indicated that Soyinka inundated his works with analogy (60%) by deploying six names (Ifada, Sunma, Samson, Simon Pilkings, Olunde, Joseph) patterned after the Holy Bible to illustrate didactic lesson and messianic scapegoatism theme(s). Furthermore, the study revealed that the playwright deployed clipping (20%) through the names Maariya and Tikim, to indicate popular culture among African youth. Finally, the playwright uses biblical names in his works to blend his Christian and traditional background, and as a means of taking indirect swipe at the issue of African complex dispositions to the colonial encounter and its legacies. The work is a contribution to onomastic scholarship in relation to the Holy Bible and African-contact literary texts
Nomes bíblicos em peças selecionadas de Wole Soyinka: um estudo sociolinguístico

Os principais dados para ilustrar a análise foram extraídos de quatro textos dramáticos: The Strong Breed (1963), The Road (1965), Death and the King’s Horseman (1975) King Baabu (2002)-todas tragédias,do mesmo autor. A fundamentação teórica adotada baseia-se na taxonomia morfológica de Yule’s (1985) e no Pós-Colonialismo de Said. Para est estudos dez nomes repletos de elementos bíblico foram selecionados e analisados usando a fundamentação teórica mencionada. Os resultados indicaram que Soyinka inundou suas obras com analogia(60%)ao empregar seis nomes (Ifada, Sunma, Samson, Simon Pilkings, Olunde, Joseph) padronizados de acordo com a Bíblia Sagrada para ilustrar lições didáticas e tema(s) de bode expiatório messiânico. Além disso,o estudo revelou que o dramaturgo utilizou truncamentos de nomes (20%)v como Maariya e Tikim, para indicar a cultura popular entre os jovens africanos. Por fim,o dramaturgo usa nomes bíblicos em suas obras para misturar sua formação cristã com sua formação tradicional, e evidenciar de forma indireta a questão das complexas atitudes africanas perante o encontro colonial e seus legados. A obra é uma contribuição à pesquisa onomástica relativa à Bíblia Sagrada e aos textos literários sobre os contatos africanos, à taxonomia morfológica deYule(1985)e ao pós-colonialismo de Said(1978)
‘Third-Worlding’ the Colonial Metropolis: Post-Colonial Travelogue, Identity and a Tale of Two Cities in Odia Ofeimun’s London Letter and Other Poems
No full textCritics assume that all autobiographical writings are essentially subject-oriented, and therefore, unsuitable as a source of social history. Because of this critical perspec tive, travelogues are regarded as subjective and self-aggrandising. However, colonialist travelogues once served Euro-America as a source of construction of the history of their colonies and mapping of their cultural landscapes. It was employed at the time as instruments of cultural prejudice and colonial agenda. Using historico-biographical reading method, this paper examines the social awareness dimension of contemporary and post-colonial travelogues and how they have served and still serve as instruments of social and cultural critique through its interrogation of the geo-cultural spaces of the colonial metropolis. This is to underline the fact that travelogues, like other autobiographical writings, combine both the functions of self understanding and social criticism. By exploring how post-colonial travelogues are potent instruments for decentering the colonial metropole and redefining both the post -colonial ‗Self‘ and the post-colony in Odia Ofeimun‘s poetic travelogue, London Letter and Other Poems, this paper shows that travelogues are socially constituted and culturally constructed as a form of social history
Effect of the school principal in creating an inclusive school culture during times of change and challenge, The
No full textThis qualitative case study examined the leadership styles that five selected school principals in southwestern Manitoba, Canada, utilize to encourage and sustain an inclusive school culture. These principals found ways to successfully embrace difficult issues and challenging people while sustaining a positive culture and building a school community that supported diversity and embraced change. The framework that undergirded this study—the critical, inclusive praxis—reinforced that the school principal was charged with the responsibility of transforming the school through reflective, critical, and dialogical action. The author engaged in an interaction (i.e., interview) with these principals to learn about their lived experiences, particularly their patterns of behaviour related to their leadership approaches within a critical inclusive praxis. The study’s conclusions confirmed that through collaboration and dialogue, by building positive relationships in safe and caring environments where there is concern for others and a supportive approach, all the while still adopting a growth mindset, these school principals built positive cultures where stakeholders felt valued, safe, respected, and included. This research deepens our collective understanding of how principals negotiate the political dynamics within their schools and vary leadership styles to encourage and sustain an inclusive school culture.Includes bibliographical references (pages 183-194).

Effect of impression material, tray space and attachment on cast accuracy
No full textAt King Saud University's College of Dentistry, final impressions for removable partial dentures are made using polysulfide rubber, fast-set and regular set irreversible hydrocolloid impression materials. Custom trays used are either single-spaced or double spaced. Further, impression material attachment to the tray could be through tray perforations or the use of adhesives. Literature to support each one of these methods separately to obtain an "accurate impression" is available. There is, however, a dearth on literature reporting on the influence of these combined variables. The purpose of this investigation was to simultaneously study the influence of impression material type, tray space and method of tray attachment on the accuracy of the resulting cast dimensions. A factorial experimental design was used. One master model representing a Kennedy Class 111 Modification 2 partial edentulous arch was used. Three reference points A, B, and C were placed on the master cast and reproduced on all experimental casts. Ten combined variables of tray space (2), impression material (3), and method of tray attachment (2) were usedCorresponding Author:
