Abstract
Purpose
This study aims to analyze and discuss the key design assumptions needed for design of car parks in steel, to highlight the impact that the increased fire loads introduced by modern cars and changes in the fire dynamics have on the design, such as fire spread leading to non-localized fires.
Design/methodology/approach
In particular, a reliable fire load density to be used for structural design of car park structures is assessed, based on investigations of the fire loads of modern cars. Based on knowledge of fire load and fire performance of cars, the consequences on the fire safety design of steel structures are presented.
Findings
Design recommendation about fire load density and fire protection of common steel profiles are given. Finally, the proposed design is compared with a design practice that has been applied in many instances for car parks constructed with unprotected steel, and recommendations for a reliable design process are provided.
Originality/value
Numerous car park buildings have recently been designed of steel structures without passive or active fire protection. The key assumptions that makes possible such design are local fire scenarios, outdated values of the car fire load and utilization of the ultimate steel strength. This paper identifies the shortcomings of such key assumptions, indicating the need for revisiting the methods and possibly even checking the analyses carried out for some already-built car parks.

Abstract
Purpose
Reinforced concrete slabs in fire have been heavily studied over the last three decades. However, most experimental and numerical work focuses on long-duration uniform exposure to standard fire. Considerably less effort has been put into investigating the response to localised fires that result in planarly non-uniform temperature distribution in the exposed elements.
Design/methodology/approach
In this paper, the OpenSees for Fire framework for modelling slabs under non-uniform fire exposure is presented, verified against numerical predictions by Abaqus and then validated against experimental tests. The thermal wrapper developed within OpenSees for Fire is then utilised to apply localised fire exposure to the validated slab models using the parameters of an experimentally observed localised fire. The effect of the smoke layer is also considered in this model and shown to significantly contribute to the thermal and thus thermo-mechanical response of slabs. Finally, the effect of localised fire heat release rate (HRR) and boundary conditions are studied.
Findings
The analysis showed that boundary conditions are very important for the response of slabs subject to localised fire, and expansive strains may be accommodated as deflections without severely damaging the slab by considering the lateral restraint.
Originality/value
This work demonstrates the capabilities of OpenSees for Fire in modelling structural behaviours subjected to non-uniform fire conditions and investigates the damage pattens of flat slabs exposed to localised fires. It is an advancing step towards understanding structural responses to realistic fires.

Abstract
Despite today’s accelerating rate and extent of change, the needed improvements within many areas of performance and quality of life have not taken place. Posits that productivity is remaining the same or even going down in many areas. Infers that learning and change have not been effective. Change involves a subject or self, who is acting, and an object which is acted on. Until now there has been an imbalanced focus on the object. In order to achieve more effective learning ‐ through a synergy of objective and subjective approaches to change ‐ suggests a comprehensive model of change where the emphasis is shifted from the object to the subject. In higher stages of human development, the subject increasingly experiences an enhanced capacity for accomplishment. Argues that this transformation of the actor provides the stable premiss for overcoming many of the shortcomings of contemporary learning and change strategies. In order to implement in practice the expanded change conception, introduces a mental technique ‐ transcendental meditation ‐ which systematically fosters human growth to higher stages of development, as shown by scientific research.

Abstract
Luminescent pigments have the property of absorbing light which falls upon them and re‐emitting it over a period of some hours, on a different wave‐length. They should not be confused with fluorescent pigments which will only emit light whilst receiving excitation, such as visible or ultraviolet light. The colour of the emission from these pigments is independent of the type of excitation.

Abstract
Purpose
The purpose of this paper is to deploy a critical discourse analysis (CDA) to consider exclusionary practices enacted by academic libraries as evidenced through resource provision. Specifically, this paper looks at the inclusion of trans and gender-nonconforming (TGNC) individuals in library guides, TGNC naming practices in abstracts and the physical shelving of transgender studies texts. This paper concludes with a discussion of methods to overcome such exclusionary practices in the future.
Design/methodology/approach
This paper deploys CDA as informed by queer theory, affording a lens to consider how language and information are structured such that particular power dynamics emerge placing symbolic value on discursively normal identities. CDA helps illuminate when, how and why TGNC individuals remain excluded within academic librarianship practices.
Findings
Findings show continued investments in heteronormative and cisnormative structures concerning information provision and access for TGNC patrons. TGNC patrons using library guides consistently fail to see any mentioned made of their respective identities aside from research about their identities. Patrons seeking information of personal value (i.e. coming out resources) find few resources. Further, library stacks and databases enact consistent microaggressions such as fetishizing, deadnaming and misgendering.
Research limitations/implications
This project contains considerable social implications, as it pushes against a continued recalcitrance on the part of academic libraries to invest in neutrality by showing its failures regarding TGNC persons.
Practical implications
This study possesses a considerable set of practical implications and highlights tangible problems that could be addressed with relative ease by academic librarians through either systemic reorganization of information or TGNC patrons. Alternatively, this work also suggests that if such reformations are not possible, academic librarians can take it upon themselves to call attention to such issues and purposefully mark these failings, thus making it clear that it is a current limitation of how libraries function and invite patrons (both cisgender and transgender) to challenge and change these representations through research and advocacy.
Social implications
This project contains considerable social implications as it pushes against a continued recalcitrance on the part of academic libraries (and librarianship more broadly) to invest in neutrality. This study contests the idea that while possessing neutrality academic libraries also posit themselves as inherently good and inclusive. By showing the violence that remains enacted upon transgender and gender nonconforming folks through multiple venues within the academic library, this study makes clear that statements of negativity are thrust onto TGNC patrons and they remain excluded from an institution that purports to have their well-being as one of its core values.
Originality/value
The deployment of CDA within information science is still a relatively new one. While linguists have long understood the multiplicity of discourse beyond language, the application of this method to the academic library as a discursive institution proves generative. Furthermore, the relationship between academic libraries and their LGBTQ+ populations is both underrepresented and undervalued, a problem exacerbated when focusing on how transgender and gender nonconforming patrons see themselves and their relationships to the academic library. This paper shows the dire state of representation for these particular patrons and provides groundwork for positively changing such representations.

Abstract
Purpose
This invited article explores current developments in supply chain risk management (SCRM) practices by revisiting the classical case of Ericsson (Norrman and Jansson, 2004) after 15 years, and updating its case description and analysis of its organizational structure, processes and tools for SCRM.
Design/methodology/approach
An exploratory case study is conducted with a longitudinal focus, aiming to understand both proactive and reactive SCRM practices using a holistic perspective of a real-life example.
Findings
The study demonstrates how Ericsson's SCRM practices have developed, indicating that improved functional capabilities are increasingly combined across silos and leveraged by formalized learning processes. Important enablers are IT capabilities, a fine-grained and cross-functional organization, and a focus on monitoring and compliance. Major developments in SCRM are often triggered by incidents, but also by requirements from external stakeholders and new corporate leaders actively focusing on SCRM and related activities.
Research limitations/implications
Relevant areas for future research are proposed, thereby increasing the knowledge of how companies can develop SCRM practices and capabilities further.
Practical implications
Being one of few in-depth holistic case studies of SCRM, decision-makers can learn about many practices and tools. Of special interest is the detailed description of how Ericsson reactively responded to the Fukushima incident (2011), and how it proactively engaged in monitoring and assessment activities. It is also exemplified how SCRM practices could continuously be developed to make them “stick” to the organization, even in stable times.
Originality/value
This is one of the first case studies to delve deeper into the development of SCRM practices through taking a longitudinal approach.

Abstract
Purpose
The purpose of this paper is to provide a basis for the construction professionals and stakeholders to understand the critical factors influencing resource availability in a post‐disaster situation. The study reported in this paper is part of ongoing research concerned with developing a methodology to improve the outcomes of resource availability for projects in post‐disaster environments. This study attempts to address the following questions: what factors impinge upon the availability of resources in a disaster recovery project and what are the common resource availability determinants across different recovery environments?
Design/methodology/approach
The method of analysis in this investigation is a comparative case study. The researchers took part in disaster field trips to Indonesia, China and Australia during their recovery from natural disasters. By using case studies and a triangulation method, critical factors that affected resource availability in the three examined countries were identified and compared.
Findings
A comparative analysis shows that specific cultural elements, the socio‐economic environment and the political agenda in the three countries influenced their resourcing problems and the solutions they adopted. Despite different resourcing approaches in the three cases, competence of construction professionals, and government response and intervention were identified as common determinants to resourcing disaster recovery projects.
Research limitations/implications
The research findings contribute to the project management methodology to post‐disaster reconstruction.
Practical implications
From this research, decision makers and construction practitioners can have a clearer direction for improving their resourcing effort in a post‐disaster situation. This study provides a basis for the construction professionals and stakeholders to understand the critical factors influencing resource availability in a post‐disaster situation, with a view to enhancing their capability of managing disaster recovery projects.
Social implications
A comparative analysis of three cases provides a multi‐perspective view of the resourcing issues in a post‐disaster situation. As many problems are faced in disaster recovery projects, resource availability intrinsically links to chronic conditions of vulnerability in existence in the broader social system prior to a disaster. The five aspects of resourcing discussed in the paper show the key areas of recovery planning in relation to resource availability.
Originality/value
In large and complex disaster recovery operations, the availability of resources is bound to be limited. Identified resourcing problems are likely to be universal and can be anticipated and pre‐planned for, irrespective of the environment when a disaster happens. The paper provides a basis for the construction professionals and stakeholders to understand the critical factors influencing resource availability in a post‐disaster situation.

Abstract
Epistemology of organizations denotes how we can gain knowledge of organizations. A critical, postmodernistic analysis suggests that the only knowledge we can gain from our traditional concepts of organization is emptiness. A proposed solution is to increase the understanding of individual and group consciousness. Individual consciousness is categorized in materialistic, dualistic and transcendent views, and group consciousness in interactive – defined in terms of its content and dependence on spatial and symbolic interaction – and collective, dependent on a subliminal transcendent consciousness. The last category is further divided into logically deduced and experiential sub‐categories. It is argued that the present understanding of organizations is based on interactive consciousness and needs to move beyond that level in order to progress. An alternative transcendent epistemology of organizations is introduced, based on transcendent experience, and a model of organization based on the transcendent epistemology is suggested. This model features a transcendent transition – transcition – as a basis for organizational change, and two cases are analyzed. It is concluded that a new paradigm based on a new science of consciousness is needed in order to do justice to the vast potential of human consciousness.

Abstract
Terrorists’ threats pose a grave danger to the health care environment in which we live. In the following paper, we look at how bioterrorist plots can effect a given population and show ways to dissect terrorist actions. We look at variables that use various cause and effect relationships, and lead the reader down a path of being able to use information presented in a real life or fictitious bioterrorist attacks. We seek to inform the reader reasons why preparedness is essential in dealing with the likelihood of the following scenarios.

Abstract
Clarifying constructs, methods, and measures for systematic research can advance knowledge about spirituality in organizations. In this paper, we define constructs of pure spirituality, applied spirituality, and spiritual development. We survey research methods for exploring spirituality in organizations – including not only objective studies but also subjective experience for personal growth. We consider five indications of spirituality – health, happiness, wisdom, success, and fulfillment – and identify research instruments for each based on measures used in prior studies of Maharishi Mahesh Yogi's Transcendental Meditation program. Research is seen as valuable for assessing the practical applications of spirituality for the individual, organization, and society.
