Abstract

Purpose

The aim of this paper is to explore the value preference space associated with the optimization and generalization performance of GEFeWSML.

Design/methodology/approach

In this paper, the authors modified the evaluation function utilized by GEFeWSML such that the weights assigned to each objective (i.e. error reduction and feature reduction) were varied. For each set of weights, GEFeWSML was used to evolve FMs for the face, periocular, and face + periocular templates. The best performing FMs on the training set (FMtss) and the best performing FMs on the validation set (FM*s) were then applied to the test set in order to evaluate how well they generalized to the unseen subjects.

Findings

By varying the weights assigned to each of the objectives, the authors were able to suggest values that would result in the best optimization and generalization performances for facial, periocular, and face + periocular recognition. GEFeWSML using these suggested values outperformed the previously reported GEFeWSML results, using significantly fewer features while achieving the same recognition accuracies statistically.

Originality/value

In this paper, the authors investigate the relative weighting of each objective using a value preference structure and suggest the best weights to be used for each biometric modality tested.

Abstract

This paper examines the evolution of two separate fields, which are essentially concerned with the same issues but are framed by different academic and professional disciplines and practice. It appears that public affairs management researchers often fail to take into account parallel literature from the discipline of public relations — even when purporting to offer an interdisciplinary approach. Equally, the public relations literature frequently fails to speak the language of business management and narrowly defines such key business activities as marketing, policy and strategy. In this paper, the authors present evidence prescribing the differing evolution of public affairs and public relations. They compare and contrast public affairs and public relations in terms of their definitions, scholarship, survey evidence, leading writers, academic and professional associations and educational programme content. They conclude by offering several suggestions for closing the gap between the two areas.

Abstract

Purpose – The purpose of this chapter is to introduce the conceptual and historical genesis of the gradual release of responsibility (GRR) model (Pearson & Gallagher, 1983) which has become one of the most commonly used instructional frameworks for research and professional development in the field of reading and literacy.

Design/Methodology/Approach – This chapter uses a narrative, historical approach to describe the emergence of the model in the work taking place in the late 1970s and early 1980s in reading research and educational theory, particularly at the Center for the Study of Reading at the University of Illinois, Champaign-Urbana as carried out by David Pearson, Meg Gallagher, and their colleagues.

Findings – The GRR Model began, in part, in response to the startling findings of Dolores Durkin’s (1978/1979) study of reading comprehension instruction in classrooms which found that little instruction was occurring even while students were completing numerous assignments and question-response activities. Pearson and Gallagher were among those researchers who took seriously the task of developing an instructional model and approach for comprehension strategy instruction that included explicit instruction. They recognized a need for teachers to be responsible for leading and scaffolding instruction, even as they supported learners in moving toward independent application of strategies and independence in reading. Based in the current research in the reading field and the rediscovery of the work of Vygotsky (1978) and the descriptions of scaffolding as coined by Wood, Bruner, and Ross (1976), Pearson and Gallagher developed the model of gradual release. Over time, the model has been adapted by many literacy scholars, applied to curriculum planning, used with teachers for professional development, reprinted numerous times, and with the advent of the Internet, proliferated even further as teachers and educators share their own versions of the model. This chapter introduces readers to the original model and multiple additional representations/iterations of the model that emerged over the past few decades. This chapter also attends to important nuances in the model and to some misconceptions of the instructional model.

Research Limitations/Implications – Despite the popularity of the original GRR model developed by Pearson and Gallagher and the many adaptations of the model by many collaborators and colleagues in literacy – and even beyond – there have been very few publications that have explored the historical and conceptual origins of the model and its staying power.

Practical Implications – This chapter will speak to researchers, teachers, and other educators who use the GRR model to help guide thinking about instruction in reading, writing, and other content areas with children, youth, pre-service teachers, and in-service teachers. This chapter provides a thoughtful discussion of multiple representations of the gradual release process and the nuances of the model in ways that will help to dispel misuse of the model while recognizing its long-standing and sound foundation on established socio-cognitive principles and instructional theories such as those espoused by Jerome Bruner, Lev Vygotsky, Anne Brown, and others.

Originality/Value of Paper – This chapter makes an original contribution to the field in explaining the historical development and theoretical origins of the GRR model by Pearson and Gallagher (1983) and in presenting multiple iterations of the model developed by Pearson and his colleagues in the field.

Abstract

Purpose – Libraries have been experiencing relentless change and uncertainty in their environment. The literature on corporate communications, strategic management and planning, marketing and public relations more recently, has been recommending using communications as a strategy to coherently and proactively handle and foresee change. Planning and using an overall communications strategy will bring integrity and adherence to the library's goals and direction while reducing the discomfort of change. This selected bibliography is a quick starting point for understanding the significance of an overall communication strategy and its use for managing conflicts and changes in the library's environment strategically. Design/methodology/approach – This article covers books and articles from mid‐1980s to 2004, published around the world. The sources are listed alphabetically by author and then chronologically for different sources by the same author, providing brief but useful information about the content covered for each source. Findings – This bibliography illustrates a variety of research from corporate communications, strategic planning, communications management, marketing and public relations literature that emphasize the role of communication in strategic management. Research limitations/implications – It records a comprehensive list of publications covering international perspectives as well as publications about communication strategy. Practical implications – This selected bibliography is primarily intended for librarians, library planners, managers or administrators, but is also relevant to corporate and business professionals, planners and administrators. Further, it would also be a useful resource for students, faculty and researchers of communication. Originality/value – This bibliography presents a much needed resource list for gathering insights into the strategic role of communication for organizations such as the library that are in a state of constant change.

Abstract

Purpose

The purpose of this paper is to examine the public relations strategies of the IRA (Irish Republican Army) and their political wing Sinn Féin, throughout the historical period known as the Northern Ireland “Troubles”.

Design/methodology/approach

This study uses semi‐structured élite interviews as its primary data. The study structures a historical account of the development of republican public relations around three main phases: the “propaganda of the deed” phase; the development of political public relations phase; and the peace process phase.

Findings

Much previous research traces a common trajectory for terrorist organisations, where they begin with large‐scale “propaganda of the deed” activities, and then move toward more typical PR activities when their “message” begins to be heard. The findings suggest that this is only partially true for the republican movement. Previous research also claims that peace settlements virtually never acknowledge the demands of terrorist groups. However, the findings indicate that the republican movement, via the use of skilful public relations techniques and disciplined internal organisational communication, pushed itself to the forefront and remained central in the efforts to develop a peace process.

Research limitations/implications

The study draws on interview data with a small group (six) of republican strategists, all of whom where involved in some capacity in public relations activities. While it is not claimed that they represent the views of the whole republican movement on the issues discussed, they do arguably represent the views of a “dominant coalition”. Future research could usefully investigate the public relations of power sharing since the Good Friday Agreement.

Originality/value

Previous approaches to analysing the subject of public relations and terrorism have tended to regard it as an activity engaged in by psychopaths or criminals. This paper's starting‐point is to problematise this definition of “terrorism” and at the same time widen the application of the term to include State actors. In this regard, it is in opposition to much current Western media, governmental and academic usage of the term. This research also differs from most other studies of terrorism in the public relations literature, in that it uses élite interviews as its primary source of data.

Abstract

Purpose

For more than four decades, scholars from diverse disciplines and countries have been interested in the act of whistleblowing. To battle financial fraud, financial regulators have been developing whistleblowing programs to motivate and protect whistleblowers, i.e. those who sound the alarm after witnessing an illegal act in their organization. The purpose of this article is to review five historical phases of whistleblowing research. The authors analyze the themes covered by whistleblowing studies conducted over the past 50 years and draw a snapshot of the evolution of whistleblowing research.

Design/methodology/approach

The authors examine academic papers published between 1970 and 2022 and inventory the disciplines involved in the literature and changes in the definition of whistleblowing.

Findings

The findings show the progress made in academic research (especially for the accounting discipline) regarding whistleblowing. The themes covered by academic studies became progressively diverse. However, this broader scope limited the depth of analysis and the level of self-criticism in the academic research. All but a few articles fail to view whistleblowing in light of its actual level of complexity, and the rationale behind limiting the definition of whistleblowing can only increase this myopia. Although most academic studies have adopted Near and Miceli (1985) definition of whistleblowing, the literature has yet to reach a consensus. Indeed, the analysis shows that Near and Miceli’s (1985) definition of whistleblowing is incomplete and narrow by today’s standards, not to mention out of step with regulators’ needs.

Originality/value

The main contributions are offering a big picture of whistleblowing academic research's evolution and proposing a more complete and updated view of this act.
