Abstract

This study investigates the complex interaction between properties of some emergent crises and the expertise of particular public sector leaders, who themselves are embedded in particular institutional processes that further constrain identification of these emergent crises. It is suggested that discrepancy in the ability of leaders to detect crises is due not only to their own proficiency in some cognitive skills, but also to their interaction with, and differences in, particular properties of some emergent crises, which render some emergent crises more detectable than others in some institutional environments.

Abstract

WITH the development of supersonic aircraft there is an increasing requirement for structural materials operating at elevated temperatures. To ensure optimum utilization of reinforced plastics it is essential to provide the designer with accurate data on performance at these temperatures.

Abstract

The nature of affect and creativity relationship has been under debate, with some studies pointing out that positive affect is conducive, while others arguing that positive affect is detrimental to creative performance. In order to clarify the complicated affect-creativity relationship, we examine several factors that have not been sufficiently looked at: the role of affect characteristics (e.g., temporal factors), neuro-cognitive mechanisms (e.g., set-breaking), and the type of creative task performed (e.g., requiring negative versus positive creativity). To improve our understanding of seemingly inconsistent previous findings, we offer a model that links affect, through a set of mediators and moderators, to creative performance in organizations, accompanying our analysis with a set of 14 testable propositions.

Abstract

Organizational creativity and innovation are inherently complex phenomena, and subject to a myriad of broad contextual and social influences. As the evidence grows for the link between innovation and organizational effectiveness and, ultimately, organizational survival, there is no doubting the need for theoretical and practical advances in our understanding. The complex nature of these constructs, however, requires that such efforts utilize a multi-level lens. This chapter discusses key aspects of creativity and innovation in organizations, including fundamental construct definition issues, which underscore the need for a multi-level perspective. It also reviews extant theoretical perspectives for their contributions to a multi-level understanding, and the research in two key areas of social influence – group factors and leadership – that have received substantial attention in the organizational literature. The review and discussion of these areas reveal not only numerous advances, but also substantial limitations that must be resolved through more complex and comprehensive (i.e., multi-level) approaches. The chapter concludes with several recommendations intended to guide and inform future work in the organizational creativity and innovation field.

Abstract

Purpose

The purpose of this paper is to design a double parabolic nozzle and to compare the performance with conventional nozzle designs.

Design/methodology/approach

The throat diameter and divergent length for Conical, Bell and Double Parabolic nozzles were kept same for the sake of comparison. The double parabolic nozzle has been designed in such a way that the maximum slope of the divergent curve is taken as one-third of the Prandtl Meyer (PM) angle. The studies were carried out at Nozzle Pressure Ratio (NPR) of 5 and also at design conditions (NPR = 3.7). Experimental measurements were carried out for all the three nozzle configurations and the performance parameters compared. Numerical simulations were also carried out in a two-dimensional computational domain incorporating density-based solver with RANS equations and SST k-ω turbulence model.

Findings

The numerical predictions were found to be in reasonable agreement with the measured experimental values. An enhancement in thrust was observed for double parabolic nozzle when compared with that of conical and bell nozzles.

Research limitations/implications

Even though the present numerical simulations were capable of predicting shock cell parameters reasonably well, shock oscillations were not captured.

Practical implications

The double parabolic nozzle design has enormous practical importance as a small increase in thrust can result in a significant gain in pay load.

Social implications

The thrust developed by the double parabolic nozzle is seen to be on the higher side than that of conventional nozzles with better fuel economy.

Originality/value

The overall performance of the double parabolic nozzle is better than conical and bell nozzles for the same throat diameter and length.

Abstract

Educational institutions in the Middle East are often criticized for using outdated teaching strategies such as lecturing that promote rote learning and memorization skills rather than life skills such as critical thinking, creativity and innovation which are important for students’ education and their future careers. This applied research paper presents an example of using Project-Based Learning (PBL) in Higher Education as a supplement to traditional lecturing and the benefits of using this approach for teaching and learning. A group of 62 female Arab students studying Emirati Studies at a federal higher institution in the UAE were involved in this classroom-based inquiry which took place over a 14-week semester. Data were collected using quantitative and qualitative methods to examine how effective the PBL approach was in engaging learners, in improving their skills and in helping them achieve the course learning outcomes. The results of the study showed that PBL was useful in helping students develop essential 21st century skills such as critical thinking, team work, problem solving, research skills, presentation skills, interpersonal communication skills, negotiation skills, creativity, and innovation. This research project helps to illustrate and provide evidence of how using PBL as a supplement to traditional lecturing can be a catalyst for an effective and efficient process-oriented quality education where students are active individuals managing their own learning and having fun in the process.

Abstract

Purpose

This paper shows that the collector (like the flâneur) is a decisive character in Walter Benjamin’s philosophy of history, specifically in the manifestation of the historical materialist, yet the paper is not so much about the collector or collecting as it is about the commodity and the experience thereof in consumer society.

Methodology/approach

The section “The Dream World of Mass Culture” discusses mass culture and the central problem of commodity fetishism as Benjamin sees it. The section “A Physiognomist of ‘the World of Things’” discusses the critical task of the historical materialist actualized and made possible through an activity akin to collecting. The section “Collecting, Child’s Play, and Seeing Similarities” illuminates the central importance of the activity of collecting for Benjamin’s research regarding mass culture, historical materialism, and the experience of modernity itself. The final section explains and fleshes out the central concepts of the mimetic faculty and physiognomic perception for Benjamin.

Findings

I find that, ultimately, to understand the ability of the historical materialist to witness history critically, according to Benjamin, is to understand the historical materialist as a collector. To understand the revolutionary activity of collecting is to understand collecting as a manifestation of a fundamental activity of human nature, the inclination to become “like” or to become “similar.” But such an impulse grounds, for Benjamin, not only the activity of collecting but also collective experience, the collective conscious, mass culture, and the essence of the commodity itself as a sociocultural artifact. The paper demonstrates that the mimetic faculty is the primary human faculty Benjamin focused on in his theory of experience.

Originality/value

The originality of this paper lies in the fact that it illustrates the primary importance of the theory of the mimetic faculty, the notion of physiognomic perception, and the work of Heinz Werner to Walter Benjamin’s theory of commodity fetishism that to date has been largely underdeveloped. But, more importantly, the paper shows that Benjamin’s theory of experience could illuminate a path toward developing a theory of experience within a fundamental philosophical anthropology.
