Abstract

Purpose

Filament wound pressure vessels have a characteristic pattern observed in their helical layers. These are mosaic‐shaped patterns and affect the layer structural behavior. The present research aims to focus on the influence of mosaic patterns on stress‐strain field and structural design of thin‐walled internally pressurized filament wound pressure vessel. The widely used stress analysis procedures and the commercially available finite element tools usually neglect the effect of the mosaic patterns. The present work seeks to deal with the modeling and stress analysis of complete pressure vessel, incorporating mosaic patterns.

Design/methodology/approach

The incorporation of the mosaic effect provides more realistic modeling of the real stress distribution and the stress values compared to the conventional analyses (the effect would depend on the shell structure, i.e. number of plies, relative thicknesses, etc.). The structural analysis is performed using commercial finite element analysis (FEA) tools ANSYS.

Findings

The comparison of results of analytical solution and conventional FEA provides close values of the stresses in the plies. As for the stress and strain distributions obtained by incorporating the effect of mosaic patterns are considerably different. The distribution of the stress and strain fields are not uniform along the length of the vessel and along its circumference and the maximum stresses acting in the direction of the fibers are higher than those calculated using conventional FEA techniques.

Originality/value

Previous work was limited to composite cylindrical shells, without incorporating the end domes. The present work deals with the modeling and stress analysis of complete pressure vessel, incorporating mosaic patterns.

Abstract

Islamic science was originally viewed as mere translator and transmitter of Greek, Indian and pre‐Islamic Persian science. Recent research has shifted our understanding of Islam's contribution to what is now called “the exact sciences.” We now know that Islamic science “was even richer and more profound than we had previously thought.” A substantial amount of genuine science was done in Islam, it predated similar discoveries in the West, and it also impacted upon the Renaissance. For example, in the late 1950apos;s, E. S. Kennedy and his students at the American University of Beirut discovered an important work of a fourteenth century Muslim astronomer by the name of Ibn al‐Shatir. This discovery showed that Ibn al‐Shatir's astronomical inventions were the same type of mechanism used by Copernicus a few centuries later,” and may have played a key role in the Copernican revolution. Consequently, an unprecedented acceleration of research into Islamic science started from the 1950s onwards. Recently, historian of Islamic science George Saliba was able to show that one of Copernicus's Muslim contemporaries — Kliafri — was a “brilliant astronomer, whose ability to work with the mathematics of his time is unsurpassed, including that of Copernicus,” and that he could use mathematics much more fluently, and much more competently, than Copernicus could do.

Abstract

Purpose

The purpose of this paper is to examine the Shariah view on the legitimacy of requiring the entrepreneur to prove that he/she has complied with all business requirements in case the actual profit was below the expected profit in trust-based contracts such as mudarabah and musharakah.

Design/methodology/approach

This paper is part of the research which applies qualitative research approaches, including among others, content analysis, interviews, observations and descriptive analysis using fiqh muqaran (comparative analysis of jurists’ arguments) in few phases.

Findings

The study found that shifting the burden of proof to the fiduciary is the weightier view and necessary to ensure that both sides are protected. The considerations of protecting people’s wealth (ḥifẓ amwāl al-nās) and mitigating widespread greed (ṭamaʿ) are among the reasons for allowing elements such as ʿurf, tuhmah and dalālat al-ḥāl to be treated as bayyinah in trust-based contracts when the fiduciary is obliged to defend himself from litigation.

Research limitations/implications

The study is meant to strengthen the practices of Islamic banks world wide.

Practical implications

Few protections can be applied for capital provider.

Social implications

This study is meant to give solution in dealing with moral hazard of both parties, and to provide solution to the regulator for policy drafting and to increase confidence to the industry.

Originality/value

The finding is important in assisting the regulators in drafting the policy to protect both parties without neglecting the essence of trust-based contracts.

Abstract

Purpose

This paper aims to investigate residents’ perceptions of tourism’s impact on their support for tourism development in Abu Dhabi, United Arab Emirates (UAE).

Design/methodology/approach

Data were collected using self-administered questionnaires from Abu Dhabi residents (n = 407), who represented 30 nationalities residing in the emirate. Based on social exchange theory, structural equation modeling was used to test hypotheses.

Findings

Results suggest that Abu Dhabi residents perceive the impacts of tourism positively and are more sensitive to the environmental and economic influences of tourism than the social and cultural influences.

Research limitations/implications

This study was limited to Abu Dhabi residents; findings cannot be generalized to other emirates in the UAE, or other countries.

Originality/value

This study adds value to extant tourism literature by investigating residents’ perceptions of the influence of tourism in one of the richest cities worldwide, which aspires to be one of the fastest growing tourism destinations in the Middle East.

Abstract

Purpose

The study aims to find the synchronization between foreign agriculture investment (FAI) and Sustainable Development Goals (SDGs) related to agriculture as classified by the Food and Agriculture Organization (FAO). The study tries to find such an association in India over 2 decades from 2001.

Design/methodology/approach

The Toda-Yamamoto Granger using the M-Wald test for the non-causality procedure is applied to find the synchronization. Stationarity is tested using the Augmented Dickey-Fuller, Phillips-Perron and Kwiatkowski, Phillips, Schmidt and Shin (KPSS) tests. The Johanson methodology with MacKinnon-Haug-Michelis P-value is employed for the Cointegration test.

Findings

The empirical results indicate that the FAI Granger cause SDG2 “Zero hunger” and “Overall sustainability”, but SDG13 “Climate Change”, SDG6 “Clean water and sanitation”, SDG12 “Responsible production and consumption” and SDG15 “Life on Land” granger cause global investments. Notwithstanding, SDG5 “Gender equality” and SDG14 “Life below water” found no-way causality with FAI.

Practical implications

Host governments should prioritize sector-level sustainable development, notably agricultural SDGs, to attract global investments. Foreign agriculture investment is influenced differently by various SDGs; thus, policymakers should concentrate on specific agricultural SDGs to enhance the flow of capital into the agriculture sector. Global investors should take sustainability into account while framing foreign investment plans, and the supra-national organization may consider global agricultural investments while addressing the problems related to global food security.

Originality/value

The distinguishing feature of the study is that SDGs classified by the FAO from a global investment perspective have not been studied so far.

Abstract

This study intends to assess the research trends on natural disasters and their contribution to the various fields of policy decisions in India by conducting a bibliometric analysis between 2008 and 2022. The Scopus database was used to extract pertinent literature. The key relevant terms were used to seek relevant papers based on the query of two searches, ‘Natural disaster and India’ scenarios combined by the Boolean operator ‘AND’. Microsoft Excel and VOSviewer-Var1.6.16 were used to assess bibliometric indicators. The database yielded 1,293 papers in all, with 14,584 citations. There were 262 single authors and 1,031 multi-author documents among the publications that were retrieved, with an average of 11.28 citations per document. After 2016, there was a dramatic growth in the total number of publications. The journal articles were the leading source of the particular literature, and this study extracted approximately 858 journal articles from the Scopus database. About 713 and 580 articles were open and closed access, respectively. Earth and planetary sciences (28.07%), social science (31.01%), and environmental science (30.39%) had a higher proportion of papers than other topics. The most impactful authors were Rajib Shaw and Filip K. Arnberg from Keio University, Japan, and Uppsala University, Uppsala, Sweden. Besides, the most funding institutions were from India (39.33%), China (13.11%), and the United States (11.9%) for natural disaster research, in the case of India. The current baseline information on natural disaster-related literature in the context of India showed that this field is growing rapidly but with inadequate research collaboration and low productivity as needed. Research collaboration in this field needs to be strengthened to improve the solid response to natural disasters in any place in India. In addition, there is a need to expand the research focus in this field to include associated indicators.

Abstract

Purpose

The purpose of this study is twofold: first, to examine the direct relationship of organizational justice (OJ), psychological empowerment (PE), Leader Member Exchange (LMX), organizational citizenship behavior (OCB), LMX on PE and OCB and PE on OCB; and second, to investigate the mediating role of PE between OJ and OCB and between LMX and OCB in the service industry in a non-Western context.

Design/methodology/approach

A quantitative questionnaire was used to test the proposed hypotheses of the study. From employees working in service providing organizations in the UAE, 364 usable responses had been collected and data was analyzed using structural equation modeling (SEM).

Findings

OJ significantly influences PE and LMX, while its influence on OCB is insignificant. Also, LMX significantly affects PE and OCB, PE significantly impacts OCB, whereas PE and LMX significantly mediate the relationship between OJ and OCB.

Practical implications

Organizations should promote fairness, psychological empowerment and OCB among employees. Additionally, leaders should develop positive and productive relationships with their employees.

Originality/value

To the best of the authors’ knowledge, this study is one of a limited number of studies designed to analyze the hypothesized relationships within a non-Western context, specifically in the UAE.

Abstract

Purpose

This research presents a framework that allows project managers to predict the next critical paths (CP(s)) and to take extra care when planning and executing those activities that have the potential to cause changes in a project's current CP(s).

Design/methodology/approach

The method presented here is based on an assessment of each activity's contribution to the overall schedule variance, which involves assigning a probability distribution function to each activity duration in the project. A sensitivity analysis is also carried out, which forms the basis of identifying which activity most affects the project completion date and therefore will have the greatest effect in changing the CP.

Findings

The authors’ analysis reveals that the most appropriate probability density function (PDF) for the targeted project is the normal distribution. However, the aim of this work is not to determine the most suitable distribution for each activity but rather to study the effect of the activity distribution type on the CP prediction. The results show that the selection of the appropriate probability distribution is very important, since it can impact the CP prediction and estimated project completion date.

Originality/value

This research work proposes a delay analysis scheme which can help the project manager to predict the next CP and to improve performance by identifying which activity is the bottleneck. On the other hand, the simplicity arises from the fact that this method does not require any expensive machines or software to generate results.

Abstract

Purpose

Application of appropriate shading device strategies in buildings can reduce direct solar heat gain through windows as well as optimize cooling and artificial lighting load. This study investigates the impact of common shading devices such as overhangs, fins, horizontal blinds, vertical blinds and drapes on energy consumption of an office building and suggests energy efficient shading device strategies in the contexts of unique Bangladeshi subtropical monsoon climate.

Design/methodology/approach

This research was performed through the energy simulation perspective of a prototype office building using a validated building energy simulation tool eQUEST. Around 100 simulation patterns were created considering various types of shading devices and building orientations. The simulation results were analysed comprehensively to find out energy-efficient shading device strategies.

Findings

Optimum overhang and fin height is equal to half of the window height in the context of the subtropical climate of Bangladesh. South and West are the most vulnerable orientations, and application of shading devices on these two orientations shows the highest reduction of cooling load and the lowest increment of lighting load. An existing building was able to save approximately 7.05% annual energy consumption by applying the shading device strategies that were suggested by this study.

Originality/value

The shading device strategies of this study can be incorporated into the Bangladesh National Building Code (BNBC) as new energy-efficient building design strategies because the BNBC does not have any codes or regulations regarding energy-efficient shading device. It can also be used as energy-efficient shading device strategies to other Southeast Asian countries with similar climatic contexts of Bangladesh.
