Abstract

Purpose

The paper seeks to perform a detailed numerical study of flow over a generic fan‐wing airfoil and also attempts to modify the geometry for the improvement of the aerodynamic performance.

Design/methodology/approach

Advanced computational fluid dynamics (CFD) technique has been employed for evaluation of the aerodynamic performance (e.g. lift/drag ratio) of a model problem. Numerical investigation starts with sensitivity studies to minimize domain size influence and grid dependency, followed by time‐accurate transient calculations. A preliminary re‐design exercise has been performed by analyzing the results of a current design.

Findings

CFD predicted lift force agrees fairly well with the measurement data with about 6.55 per cent error, while drag force compares less favourably with about 12.59 per cent error. Both errors are generally acceptable for an engineering application of complex flow problems. Several key flow features observed previously by experiment have also been re‐produced by simulation, notably the eccentric vortex motions in the blade interior and the stream “jet” flow outside the blades near the exit. With the modified geometry, there is a considerable lift/drag ratio improvement of about 29.42 per cent. The possible reasons for such a significant improvement have been discussed.

Research limitations/implications

As it is the first step towards the detailed flow analysis of this type of model, a simpler blade shape rather than “real” one has been used.

Practical implications

The paper provides a very useful source of information and could be used as guidance for further industry practice of unmanned aerial vehicles design.

Originality/value

This paper is valuable for both academic researchers and industry engineers, especially those working in the area of high‐lift wing design. The works presented are original.

Abstract

Purpose

In his recent report, Lord Adebowale (2013) described mental health issues as “core police business”. The recent retrenchment in mental health and wider public services mean that the demands on the police in this area are likely to increase. Mental health triage is a concept that has been adapted from general and mental health nursing for use in a policing context. The overall aim of triage is to ensure more effective health outcomes and the more effective use of resources. The purpose of this paper is to examine the current policy and practice in this area. It then goes on to explore the models of mental health triage that have been developed to try and improve working between mental health services and the police.

Design/methodology/approach

The paper outlines the main themes in the research literature regarding mental illness and policing, including a brief overview of section 136 MHA. It then examines recently developed models of triage as applied in these settings.

Findings

The models of triage that have been examined here have developed in response to local organisational, demographic and other factors. The approaches have two key features – the improved training for officers and improved liaison with mental health services.

Practical implications

Wider mental health training for officers and improved liaison with community-based services are the key to improving police contacts.

Social implications

The current pressure on mental health services has increased the role that the police have in responding to these sorts of emergencies. This situation is unlikely to change in the short term.

Originality/value

This paper contributes to the wider debate about policing and mental illness. It highlights the fact that section 136 MHA use has tended to dominate debates in this area to the detriment of a broader discussion of the police role.

Abstract

In this chapter, the authors provide an introspective account of how teachers in mainstream classrooms can use questioning to more effectively differentiate literacy instruction for English learners across subject areas. The authors offer a rationale for constructively responsive questioning and share tools and strategies for adapting levels of questioning to students’ English proficiency and grade levels with the goal of strengthening instruction and promoting student engagement in learning.

Abstract

Purpose

This paper aims to understand better how strategic management (SM) affects organizational and operational performance by examining the mediating role of dynamic capabilities (DCs) in complex environments.

Design/methodology/approach

This study uses a survey of a sample of managers (n = 480) from each logistics firm and applies structural equation modeling to determine the relationships among variables.

Findings

The analyses identify SM directly and DCs as a mediator significant antecedent for the operational performance; further, environmental complexity shows an impact as a significant factor on both variables.

Research limitations/implications

One of the managerial implications is that acquiring-sensing the environment should be orchestrated to be effective.

Originality/value

Previous DC literature studied underdeveloped DCs in complex environments and ignored the manager’s role as a connection between the environment and the firm. This paper contributes to the topic in three important ways: first, it clarifies the operational performance from the combination of the design of the DCs and the SM characteristics within the complex environment; second, the paper specifies that microfoundations of DCs are essential in the drive’s differences in the performance of the firms; and third, it clarifies regarding the role of the complex external environment rather than dynamic ones.

Abstract

This chapter argues that the near-universal exclusion from the academy of the Shakespeare Authorship Question (or SAQ) represents a significant but little-understood example of an internal threat to academic freedom. Using an epistemological lens, this chapter examines and critiques the invidious and marginalizing rhetoric used to suppress such research by demonstrating the extent to which it constitutes a pattern of epistemic vice: that, by calling skeptics “conspiracy theorists” and comparing them to Holocaust deniers rather than addressing the substance of their claims, orthodox Shakespeare academics risk committing acts of epistemic vice, injustice and oppression, as well as foreclosing potentially productive lines of inquiry in their discipline. To better understand this phenomenon and its implications, the chapter subjects selected statements to external criteria in the form of the Association of College and Research Libraries’ 2015 Framework for Information Literacy for Higher Education, which provides a set of robust normative dispositions and knowledge practices for understanding the nature of the scholarly enterprise. The analysis reveals that the proscription against the SAQ constitutes an unwarranted infringement on the academic freedom not only of those targeted by this rhetoric, but – by extension – of all Shakespeare scholars as well.

Abstract

Antonioni, Berger, Magritte and Sontag, with their respective challenges to our perceptions of what is real and unreal, set the scene for a discussion of the tension between current policies and norms in higher education systems and the increasingly important need to introduce true interdisciplinarity in university programmes – specifically, here, with regard to the role of the humanities in business-related courses. It is argued that uncertainty and imperfection are key signposts to creativity and innovation. Uncertainty demands the constant search for possibility; imperfection provides the constant opportunity to improve and is therefore the inspiration for innovation. In an exploration focussing principally on the various potentialities of the study of literature, it is suggested that many initiatives to introduce the arts into non-humanities programmes have a common and significant limitation in that they are defined by a specific purpose – by an understandable and, in our current higher education environments, an inevitable need to specify what ‘impact’ the intervention will have on the skills and employability of the student. However, something much more radical is needed if what George Eliot called the ‘vital connections of knowledge’ are to be truly made, and the radical adjustment required runs directly counter to a culture that is dominated by the compulsion to demonstrate impact, set measurable targets and prioritize practical application.

Abstract

Purpose

The purpose of this paper is to characterize the internal dynamics of cross-functional teams (CFTs) in different organizational processes in a service company.

Design/methodology/approach

A case study from a Brazilian service company was conducted. CFTs in five different organizational processes (strategy development, product development, portfolio management, sales channels management and business analysis) were analyzed through in-depth interviews, documents and non-participant observation.

Findings

A framework with four pillars was constructed: constitution of the CFT, task drivers, behavior and attitudes of the team and personal motivators. It was possible to analyze the process of how a group acts and reacts under changing circumstances based on the pillars included in the framework.

Research limitations/implications

The study is focused on creating analytical generalizability. Several insights in the 12 propositions presented in this study may be investigated in future research to validate the identified relationships among the pillars included in the framework. Moreover, the proposed framework allows the teams to be analyzed through a multidimensional view: structure, processes and impacts.

Practical implications

If the semantic boundaries of the communication are not well delineated, the differences in understanding can generate manifest conflicts. Moreover, the workload in a CFT seems to be larger and more complex than working in a functional activity; however, members perceive that it reduces the risk of unemployment and increases motivation.

Originality/value

The present study contributes to the extant literature with the proposal of a set of new exploratory propositions that can support future quantitative research about the use of CFTs in the service industry context.
