Abstract

Purpose

The purpose of this study is to critically review the book Islamic Law and International Law by Emilila Powell.

Design/methodology/approach

The book review is undertaken from a comparative legal and political science perspective, including arguments and insights from international relations, international law, Islamic law, Islamic culture, religious studies, legal history and European as well as international political history.

Findings

While the empirical part of Powell’s work (chapters 5, 6 and 7) shows a methodologically veryc well done approach and at the same time highly interesting insights, both foundation and context show several critical points, in particular, a lack of differentiation with respect to the Western politico-legal tradition, its concepts and the resulting implications.

Research limitations/implications

The book represents an excellent starting point that should inspire new, more intensive as well as exhaustive research on this topic.

Practical implications

The book generates valuable insights for practitioners such as judges at international courts dealing with issues involving so-called Islamic law states, as well as politicians or public service officials in the context of international law and international politics.

Originality/value

As the paper is a comprehensive review of the book based upon comparatively based insights from international relations, international law, Islamic law, Islamic culture, religious studies, legal history and European as well as international political history, the arguments of Powell are analyzed and commented upon in a comprehensive, well-founded and fair way. This should give potential readers a good understanding of Powell’s arguments, inspire a critical lecture of the book and contribute to the important discourse on the connex between international law and Islamic law.

Abstract

Brad Powell, the newly hired senior leader of a Christian church, must lead the organization to reverse a three-decade decline and return to fulfilling its mission. Brad spent the first six months assessing the situation, building relationships, and reiterating the longstanding mission of the organization. Now, with an understanding of its history, an intimate knowledge of the immediate challenges, and a clear vision of what the organization should become, Brad is considering his strategy and next steps. As the leader of a nonprofit organization resourced by members and volunteers, Brad must lead change that produces results without compromising the mission. The B case summarizes Brad's actions and the results.

To allow students to evaluate Brad's situation and advise him on the best plan for leading change at Temple Baptist Church. To demonstrate the impact of a leader on an organization's culture, and the fit between an organization's style and its mission. To allow discussion of the paradoxes a leader must manage in changing a culture, measuring financial versus nonprofit results, leading volunteers versus paid staff, upholding mission versus tradition, and leading change with limited resources.

Abstract

Purpose

The purpose of this study is to examine the non-Newtonian physical model of Eyring–Powell fluid for the rheology inside a long circular pipe.

Design/methodology/approach

Although many research studies are available now on this topic, none gives full solutions explicitly accessible.

Findings

It is proven here that the hydrodynamically fully developed fluid flow acknowledges the exact solution, influenced by a non-Newtonian parameter as well as the adverse pressure gradient parameter prevailing the flow domain. These parameters are unified under a new parameter known as the generalized Eyring–Powell parameter. Without the presented analytical data, it is impossible to detect the validity range of such physical non-Newtonian solutions, which is shown to be restricted.

Originality/value

Full solution of the energy equation for the thermally fully developed laminar regime is also presented under the assumption of uniform wall temperature at the pipe wall. The physical impacts of pertinent parameters on the rheology of the non-Newtonian fluid with regard to the Reynolds number, Darcy friction factor and pressure drop are easy to interpret from the derived formulae. Particularly, a decrease in the centerline velocity and an increase in the rate of heat transfer are clarified for the considered flow configuration.

Abstract

Purpose

The purpose of this paper is to scrutinize the effects of nonlinear thermal radiation and thermal stratification effects on the flow of three-dimensional Eyring-Powell 36 nm alumina-water nanofluid within the thin boundary layer in the presence of quartic autocatalytic kind of chemical reaction effects, and to unravel the effects of a magnetic field parameter, random motion of the tiny nanoparticles and volume fraction on the flow.

Design/methodology/approach

The chemical reaction between homogeneous (Eyring-Powell 36 nm alumina-water) bulk fluid and heterogeneous (three molecules of the catalyst at the surface) in the flow of magnetohydrodynamic three-dimensional flow is modeled as a quartic autocatalytic kind of chemical reaction. The electromagnetic radiation which occurs within the boundary layer is treated as the nonlinear form due to the fact that Taylor series expansion may not give full details of such effects within the boundary layer. With the aid of appropriate similarity variables, the nonlinear coupled system of partial differential equation which models the flow was reduced to ordinary differential equation boundary value problem.

Findings

A favorable agreement of the present results is obtained by comparing it for a limiting case with the published results; hence, reliable results are presented. The concentration of homogeneous bulk fluid (Eyring-Powell nanofluid) increases and decreases with ϕ and Pr, respectively. The increase in the value of magnetic field parameter causes vertical and horizontal velocities of the flow within the boundary layer to decrease significantly. The decrease in the vertical and horizontal velocities of Eyring-Powell nanofluid flow within the boundary layer is guaranteed due to an increase in the value of M. Concentration of homogeneous fluid increases, while the concentration of the heterogeneous catalyst at the wall decreases with M.

Originality/value

Considering the industrial applications of thermal stratification in solar engineering and polymer processing where the behavior of the flow possesses attributes of Eyring-Powell 36 nm alumina-water, this paper presents the solution of the flow problem considering 36 nm alumina nanoparticles, thermophoresis, stratification of thermal energy, Brownian motion and nonlinear thermal radiation. In addition, the aim and objectives of this paper fill such vacuum in the industry.

Abstract

This issue's Stack attacks the question of how leaders can move from what they want to achieve to actually achieving it through themselves, teams, peers, and their organizations. The most successful are Execution, First Among Equals, and The Leadership Secrets of Colin Powell. All three can manage to satisfy strategy's old hands and newcomers alike.

Abstract

Informed by multiple disciplines, theories, and methods, higher education scholars have developed a robust and diverse literature in many countries. Yet, some important (organizational) sociological perspectives, both more established and more recent, are insufficiently linked. In particular, we identify two theoretical strands – institutional and relational – that, when joined, help to explain contemporary developments in global higher education and yield new organizational insights. We review relevant literature from each perspective, both in their general formulations and with specific reference to contemporary higher education research. Within the broad institutional strand, we highlight strategic action fields, organizational actorhood, and associational memberships. Within the relational strand, we focus on ties and relationships that are especially crucial as science has entered an age of (inter)national research collaboration. Across these theories, we discuss linkages between concepts, objects, and levels of analysis. We explore the methodological approach of social network analysis as it offers great potential to connect these strands and, thus, to advance contemporary higher education research in a collaborative era.

Abstract

Knowledge of how institutions “work on the ground” is central to understanding how macro-pressures shape organizations and their participants. Four examples of the interplay between micro and macro are provided to give a richer account of institutions, both as process and outcome. One, as wider trends diffuse, they are pulled down locally, but the scripts are utilized in divergent ways. Two, as organizations make sense of social forces, these movements are received differentially, with micro-practices and macro-influences becoming entangled. Three, trends can be opaque to those who seek to follow them, resulting in unintended forms of implementation. Four, sociological miniaturism illustrates how the micro captures the macro as lived experience.

Abstract

In February 2018, Jerome Powell had taken over as chair of the FOMC. At first glance, the macroeconomic conditions inherited by Powell appeared favorable for continued stability: unemployment and inflation were low, and the economy had been steadily growing for nearly a decade. Yet despite the appearance of stability, the economy faced significant risks that required the Federal Reserve's attention. Was an uptick in inflation imminent, and if so, should Powell raise rates to limit any inflationary pressure? Or was the economy still operating below capacity, and if so, should the Federal Reserve take a more accommodative stance? To gain perspective, Powell needed to look back at the past fifty years of monetary policy in the United States.

Abstract

Purpose

The purpose of this study is, mixed convection on magnetohydrodynamic (MHD) flow of Eyring–Powell nanofluid over a stretching cylindrical surface in the presence of thermal radiation, chemical reaction, heat generation and Joule heating effect is investigated and analyzed. The Brownian motion and thermophoresis phenomenon are used to model nanoparticles (Buongiorno’s model).

Design/methodology/approach

The numerical method is applied to solve the governing equations. Obtained results from the effects of different parameters changes on velocity, temperature and concentration profiles are reported as diagrams.

Findings

As a result, velocity profile has been reduced by increasing the Hartman number (magnetic field parameter) because of the existence of Lorentz force and increasing Eyring–Powell fluid parameter. In addition, the nanoparticle concentration profile has been reduced because of increase in chemical reaction parameter. At the end, the effects of different parameters on skin friction coefficient and local Nusselt number are investigated.

Originality/value

Eyring–Powell nanofluid and MHD have significant influence on flow profile.
