Abstract
An extension is made to the theory on which most aircraft pressure cabins are designed. In the existing theory the effect of the curvature of the deformed cylinder is neglected. This paper examines the manner in which this effect influences the stress distribution.

Abstract
THE structural design of a long range ballistic missile or a space rocket vehicle is an intriguing problem. It is hardly necessary to stress the importance of achieving as light a structure as possible, since any unnecessary increase of structural weight can severely affect its performance or result in a profound increase of its total weight. There is a dearth of published information on this subject, presumably because of security restrictions. Among the papers available, only Sechler dwells on the structural design consideration in any detail. We have therefore very few specific facts to guide us, and can only relate the problem to our aircraft design experience with commonsense.

Abstract
Petroleum resource-based city is an important part of urban system in China. Under the background of green growth and economic transition, petroleum resource-based city is facing the problem of sustainable development. This paper takes petroleum resources-based cities in China as the research object, and uses urban ecological planning method to analyze the basic methods of petroleum resources-based urban ecological planning and development from three aspects: establishing multi-level city circle layer, building urban ecotope and promoting urban renewal. The results show that green growth and economic transition of petroleum resources cities in China depend on government planning for urban development, including statutory planning and non-statutory planning. Petroleum resources-based cities should promote the ecological planning and development of petroleum resources-based cities in China from three aspects: optimizing the industrial structure of cities, optimizing the layout of urban functional areas and optimizing the layout of urban ecolandscape in order to adapt to green growth and economic transition.

Abstract
Successful smart cities' implementation will require organisational leadership decision-making competences. The foundation of smart cities is digital technologies; many of these technologies are emerging technologies that require IT skills, which are scarce and will exacerbate the battle for talent between organisations. Filling the talent gap will necessitate global hiring, which has implications for organisational culture, cultural diversity and organisational leadership. Organisational cultural mix is an important contributor to leadership decision-making. However, decision-making is underpinned by trust. Blockchain is an emerging technology that has the potential to engender organisational trust in decision-making and, by extension, in the leadership with the ‘right’ organisational culture. Smart cities will be required to leverage emerging technologies to give business performance a competitive advantage and use emerging technologies’ applications to build a sustainable competitive advantage.

Abstract
SUMMARY An analysis is given for the buckling of a simply supported rectangular plate under the combined action of a number of in‐plane stresses. These stresses could arise in the various plate elements of the structure of a high‐speed aircraft, due to the combined action of aerodynamic and inertia forces with additional kinetic heating effects. The buckling solution of a wing spar web is considered, and the buckling criterion is presented in the form of a determinantal equation which may be evaluated to give the magnitude of the critical thermal stress under a given loading system.

Abstract
Purpose
The purpose of this study is to conduct a systematic review of the extant literature of workplace spirituality (WPS) in a manner that helps us trace its emergence in management practices in the past twelve years and to identify the gaps to be addressed by researchers in near future.
Design/methodology/approach
A two-step screening process was followed to extract the papers from various databases. The paper reviews one hundred fifty-nine conceptual and empirical articles published in more than fifty journals from 2010 to 2021. Leading databases like EBSCO, Scopus and ProQuest were extensively searched. The papers were analysed and grouped to arrive at the themes and classification criteria.
Findings
Despite numerous studies and extensive research in the past decade, the construct of WPS lacks a conclusive definition and has overlapping dimensions. It is a multidimensional concept having personal, psychological and social aspects. It is a dominant field in organisational behaviour domain.
Research limitations/implications
The review explains the multidisciplinary nature of WPS, having roots in organisational behaviour, psychology and theology. Further, the paper provides a clear picture of the present state of literature and enumerates future research avenues which will enable the researchers to further expand the area of WPS.
Practical implications
The review highlights multiple positive attitudinal outcomes that managers can attain through WPS-related initiatives. Various techniques like prayer breaks, meditation and yoga can be used by the managers for spiritual incorporation process.
Originality/value
This study acquires significance, for, unlike previous studies, it does not propose that inclusion of WPS will always be gainful, rather it also broaches its potential harm, if incorporated sans due caution. Considering the complexity of spiritual beliefs, it will enable managers to weigh the pros-cons of such inclusion. The research gaps identified in the review will help future researchers in furthering the field of WPS.

Abstract
Purpose
The main aim of this study is to examine a moderated–mediated model empirically to understand whether and how spiritual leadership (SL) affects corporate social entrepreneurial orientation (SEO) with the role of workplace spirituality (WS).
Design/methodology/approach
The study adopts a sample of 524 key role employees at 76 four–five-star hotels and tourism firms in Ho Chi Minh City of Vietnam, using a partial least square structural equation model (PLS-SEM).
Findings
SL of social entrepreneurs can vigorously promote corporate SEO's formation and development, with WS's mediating role.
Originality/value
This study demonstrates how SL and WS can help organisations achieve higher corporate SEO levels in contradictory empirical evidence and a lack of theoretical framework.
