Abstract

Purpose

Although the importance of climate change is generally acknowledged, its impacts are often not taken into account explicitly when planning development projects. This being due to limited resources, among others, this paper aims to propose a simple and low-cost approach to assess the viability of human activities under climate change.

Design/methodology/approach

Many human activities are feasible only within a narrow range of climatic conditions. Comparing such “climate corridors” with future climate projections provides an intuitive yet quantitative means for assessing needs for, and the viability of, adaptation activities under climate change.

Findings

The approach was tested within development projects in Pakistan, Peru and Tajikistan. The approach was shown to work well for forestry and agriculture, indicating positive/negative prospects for wheat in two districts in Pakistan, temperature constraints for maize in Peru and widening elevation ranges for walnut trees in Tajikistan.

Practical implications

Climate corridor analyses feed into the preparation of Local Adaptation Plans of Action in Pakistan.

Originality/value

The simplicity and robustness of climate corridor analysis allow for efficient analysis and communication of climate change impacts. It works when data availability is limited, but it can as well accommodate a wide range of complexities. It has proven to be an effective vehicle for mainstreaming climate change into adaptation planning.

Abstract

Purpose

To examine the implications of the cessation of LIBOR in the context of Islamic finance transactions and to suggest potential solutions for the Shari’ah-compliant use of near risk-free reference rates (RFRs) in such transactions.

Design/methodology/approach

Provides an overview of the main regulatory changes by the UK’s Financial Conduct Authority (FCA) to LIBOR, a review of the key details regarding the cessation of LIBOR and specific risk factors, a discussion of core concepts of Islamic finance and the unique challenges that the models face considering the LIBOR reforms, and an outline of several innovative solutions that can be utilized by organizations and institutions to overcome the potential complexities of the LIBOR reforms.

Findings

The financing component of a seller’s profit margin in a murabaha transaction may be calculated using LIBOR, a forward-looking rate. LIBOR as a financing rate benchmark is being replaced by RFRs, which are backward-looking rates. A possible way to use RFRs in a murabaha transaction might be to recalculate the seller’s profit margin depending on actual RFRs during the financing period with the seller offering appropriate rebates to the buyer.

Originality/value

Expert guidance from experienced corporate, financing, investment, and Islamic financing lawyers.

Abstract

Purpose

This paper aims to design a dual mode X-band substrate integrated waveguide (SIW) bandpass filter in the conventional SIW structure. A pair of back-to-back square and split ring resonator is introduced in the single-layer SIW bandpass filter. The various coupling configurations of SIW bandpass filter using split square ring slot resonator is designed to obtain dual resonant mode in the passband. It is shown that the measured results agree with the simulated results to meet compact size, lower the transmission coefficient, better reflection coefficient, sharp sideband rejection and minimal group delay.

Design/methodology/approach

A spurious suppression of wideband response is suppressed using an open stub in the transmission line. The width and length of the stub are tuned to suppress the wideband spurs in the stopband. The measured 3 dB bandwidth is from 8.76 to 14.24 GHz with a fractional bandwidth of 48.04% at a center frequency of 11.63 GHz, 12.59 GHz. The structure is analyzed using the equivalent circuit model, and the simulated analysis is based on an advanced design system software.

Findings

This paper discusses the characteristics of resonator below the waveguide cut-off frequency with their working principles and applications. Considering the difficulties in combining the resonators with a metallic waveguide, a new guided wave structure – the SIW is designed, which is synthesized on a planar substrate with linear periodic arrays of metallized via based on the printed circuit board.

Originality/value

This study has investigated the wave propagation problem of the SIW loaded by square ring slot-loaded resonator. The electric dipole nature of the resonator has been used to achieve a forward passband in a waveguide environment. The proposed filters have numerous advantages such as high-quality factor, low insertion loss, easy to integrate with the other planar circuits and, most importantly, compact size.

Abstract

Levels of selected essential metals (Cu, Fe and Zn) and non‐essential metals (Cd and Pb) were determined by the wet digestion based atomic absorption flame spectrophotometric method in twenty canned foodstuffs of local and foreign origin. The study revealed that on average, the concentrations of Fe, Cd and Pb in local foodstuff were more than those found in imported canned products. The contents of Fe and Pb in local canned food were almost double that of the counterpart imported versions. Analysis of the construction materials of the tins indicated that some metals, such as Pb, had levels twice as high as those found in the foreign tin containers. The results showed that the Cu concentration in various foodstuffs ranged between 0.04 and 8.88mg/kg, Fe between 3.07 and 126mg/kg, Zn between 0.19 and 22.8mg/kg, Cd between 0.15 and 1.16mg/kg and Pb between 0.11 and 2.04mg/kg. The results are compared with the levels of metals in corresponding data from the literature.

Abstract

Purpose

In the vast majority of published papers, the optimal allocation of photovoltaic distributed generation (PVDG) units and reconfiguration problems are proposed along with the number of PVDG used in the simulation. However, optimisation without selecting the number of PVDG units installed in the distribution grid is insufficient to achieve a better operational performance of power systems. Moreover, multi-objective installation of PVDG units and reconfiguration aims to simultaneously relieve congestion problems, improve voltage profile and minimise the active and reactive power losses. Therefore, this paper aims to propose a new modified camel algorithm (NMCA) to solve multi-objective problems considering radial distribution system to achieve secure and stable operation of electric power system with good performance.

Design/methodology/approach

In this paper, the decision variables include the location and size of PVDG units with specific rang to determine the number of PVDG units needed to install and open network lines determined using NMCA based on the L_∞ technique. This also satisfies the operating and radial constraints. Furthermore, a benchmark comparison with different well known optimisation algorithms has been made to confirm the solutions. Finally, an analysis of the findings was conducted, and the feasibility of solutions was fully verified and discussed.

Findings

Two test systems – the institute of electrical and electronics engineers (IEEE) 33-bus and IEEE 69-bus, were used to examine the accuracy and effectiveness of the proposed algorithm. The findings obtained amply proved the efficiency and superiority of the NMCA algorithm over the other different optimisation algorithms.

Originality/value

The proposed approach is applied to solve the installation PVDG unit’s problem and reconfiguration problem in the radial distribution system, satisfying the operating and radial constraints. Also, it minimises active and reactive power losses and improves voltage profile.

Abstract

Purpose

The purpose of this paper is to examine gender inequality in Saudi Arabia by using a relational perspective that takes into account the interrelated nature of the multilevel factors that influence this phenomenon.

Design/methodology/approach

A total of 21 in-depth interviews with female employees in Saudi Arabia were conducted and analysed using a thematic analysis.

Findings

The findings show how the interplay of factors on macro, meso and micro levels influences equal opportunities for women in Saudi Arabia, such as religio-cultural factors, the social power of wasta, the notions of female modesty and family honour and issues related to gender segregation, discrimination and harassment at work. Moreover, Saudi women’s experiences are varied on the basis of social class, family status and other dimensions of individual identity, adding to a growing body of intersectional research. The paper highlights the role of male guardianship system as well as the intersection of gender and class in pushing gender equality forward.

Originality/value

This study stresses the interrelated nature of the multilevel factors that affect gender equality and highlights the important role of individual agency and resilience.
