Abstract
Flood vulnerability is a complex concept involving the interactions between environment, social and economic dimensions. Indicator‐based vulnerability assessment is widely used in vulnerability studies to summarise complexity and multidimensionality issues to gauge the level of vulnerability. A set of 21 environmental and socio‐economic indicators is used to quantitatively assess the three factors of vulnerability, namely exposure, susceptibility and resilience to flood at the subnational level. The construction of the vulnerability index involved the selection of indicators, their normalisation, weightage and aggregation to a final index. In addition to the Flood Vulnerability Index, three sub‐indices namely Exposure Index, Susceptibility Index and Resilience Index were generated. Based on composite indicator approach, the vulnerability of the states in Malaysia was categorised from very low to very high. The source of vulnerability is due not only to the environmental exposure to flood hazard but also contributed by the internal status of the socio‐economic factors within the vulnerable systems.

Abstract
Purpose
In the online environment, consumers increasingly feel vulnerable due to firms’ expanding capabilities of collecting and using their data in an unsanctioned manner. Drawing from gossip theory, this research focuses on two key suppressors of consumer vulnerability: transparency and control. Previous studies conceptualize transparency and control from rationalistic approaches that overlook individual experiences and present a unidimensional conceptualization. This research aims to understand how individuals interpret transparency and control concerning privacy vulnerability in the online environment. Additionally, it explores strategic approaches to communicating the value of transparency and control.
Design/methodology/approach
An interpretivism paradigm and phenomenology were adopted in the research design. Data were collected through semi-structured interviews with 41 participants, including consumers and experts, and analyzed through thematic analysis.
Findings
The findings identify key conceptual dimensions of transparency and control by adapting justice theory. They also reveal that firms can communicate assurance, functional, technical and social values of transparency and control to address consumer vulnerability.
Originality/value
This research makes the following contributions to the data privacy literature. The findings exhibit multidimensional and comprehensive conceptualizations of transparency and control, including user, firm and information perspectives. Additionally, the conceptual framework combines empirical insights from both experiencers and observers to offer an understanding of how transparency and control serve as justice mechanisms to effectively tackle the issue of unsanctioned transmission of personal information and subsequently address vulnerability. Lastly, the findings provide strategic approaches to communicating the value of transparency and control.

Abstract
Purpose
The purpose of this paper is to set forth a rigorous methodology for building owners and managers to conduct a vulnerability assessment of their facilities. Such a process would facilitate the use of remediation measures to limit the loss of life and property during a disaster, whether natural or man‐made.
Design/methodology/approach
The author sets forth nine criteria to conduct a vulnerability assessment, along with a six‐point rating system. The criteria selected are: the level of visibility, the criticality of the site to the jurisdiction in which it is located, the impact of the site outside of the jurisdiction in which it is located, access to the site, size hazards, building height, type of construction, site population capacity, and the potential for collateral mass casualties. This evaluative process leads to five site vulnerability ratings, ranked as follows: negligible, low, medium, high, and critical.
Findings
Property owners and building managers can use this process to assess the vulnerability of their facilities and, based on this process and the resulting vulnerability rating, initiate common‐sense remediation measures to limit the loss of life and property, should a disaster occur.
Research limitations/implications
The field of vulnerability assessment is a new discipline within the evolving subject of homeland security. Other methodologies will be needed in the future to determine the vulnerability of other public and private facilities, such as ports, airports, transportation centers, hospitals, colleges and universities, and other vital public and private facilities.
Practical implications
This research provides a framework for future research on the topic of vulnerability assessments. Refinements and modifications can be made to the proposed methodology (both to the vulnerability assessment criteria and to the vulnerability ratings).
Originality/value
This paper provides original research and sets forth a new methodology for conducting vulnerability assessments of public and private buildings.

Abstract
Purpose
To develop a decision model supporting employee involvement in industrial vulnerability reduction.
Design/methodology/approach
A synthesis review of some of the relevant extant literature on technological/industrial vulnerability, and their application within a normative decision‐making model (i.e. the “Vroom‐Yetton model”).
Findings
The insights on vulnerability drawn from the literature are highly amenable to a systematic decision‐making model for employee involvement. Various aspects of vulnerability, specifically with regard to substantial, social and temporal dimensions may be included in such a model.
Research limitations/implications
New insights about the context‐dependent aspects of vulnerability are offered by considering these within a contingency decision model. This suggests that vulnerability categories are not absolute, but have to be assessed in relation to a specific decision‐making framework.
Practical implications
The developed model provides a way of weighting various dimensions of vulnerability and making more appropriate decisions regarding leadership style in a range of circumstances.
Originality/value
While decision models exist for assessing risk in organizations, no contingency model for employee involvement in vulnerability assessment has been presented to date.

Abstract
Purpose
Assessing project criticality in a project portfolio (PP) is of great practical significance to improve robustness from damage. While project criticality assessment has increased diversity in approaches, the understanding of vulnerable project impacts is still limited. To promote a better understanding of assessing project criticality, a vulnerability measurement model is constructed.
Design/methodology/approach
First, integrating the tasks, projects and corresponding relationships among them, a project portfolio network (PPN) is constructed. Second, the project's vulnerability is measured by combining the topological structure and functional attributes. Third, project criticality is assessed by the vulnerability measurement results. Lastly, the proposed model is applied in a numerical example to illustrate its suitability and effectiveness.
Findings
For academia, this study provides a novel perspective on project vulnerability measurement and expands project criticality assessment tools. For practitioners, the straightforward model provides an effective tool for assessing project criticality and contributes to enhancing project portfolio management (PPM).
Originality/value
The impact of the task on the project is considered in this study. Topological structure and functional attributes are also integrated for measuring project vulnerability due to the impact of random attacks in an uncertain environment, providing a new perspective on the requirements of project criticality assessment and the measurement of project vulnerability.

Abstract
Purpose
The purpose of this study results and recommendations will have a paramount significance for policymakers, policy advocates, development planners and practitioners who may be in need of such information for reconsideration, evaluation and inclusion into their respective development and humanitarian programming and operational strategies. Above all, the study result has further provided the local community with viable adaptation strategies to climate-induced changes in the study area.
Design/methodology/approach
This study was conducted to measure the livelihood vulnerability of Borana pastoralists to climate change and variability in southern Ethiopia. Pastoralists’ households were sampled using multistage sampling techniques. A total of 27 socio-economic and biophysical indicators were used to reflect vulnerability components: adaptive capacity, exposure and sensitivity. Principal component analysis was used to develop weights for indicators and to produce livelihood vulnerability index to classify households according to their level of vulnerability. Ordinal logistic regression was used to identify the determinants of vulnerability to climate-induced stresses.
Findings
The results showed that 24.4% of households were highly vulnerable, 60.3% were moderately vulnerable and 15.3% of households were less vulnerable to climate-induced stresses. Factor estimates of the logistic model further revealed that early warning information, bush encroachment, coping strategy, temperature, drought frequency, provision of humanitarian services and food shortage during the normal season of the year have a significant influence on vulnerability in the study area.
Social implications
The study’s results and recommendations will be of great significance to policymakers, development planners, and practitioners who require such information for reconsideration, evaluation, and inclusion in their respective development and humanitarian program and operational strategies. Most importantly, the study’s findings have provided the local community with practical adaptation strategies to climate-induced changes in the study area.
Originality/value
The study explored pastoralist perception of climate change and variability and measured the livelihood vulnerability of pastoralists’ households to climate change and variability and finally investigated viable adaptation and coping strategies in the study area.

Abstract
Purpose
Preventative health services are keen to identify how to engage men and increase their participation, thus improving health, well-being and life expectancy over time. Prior research has shown general gender norms are a key reason for men’s avoidance of these services, yet there is little investigation of specific gender norms. Furthermore, masculinity has not been examined as a factor associated with customer vulnerability. This paper aims to identify the relationship between gender norm segments for men, likely customer vulnerability over time and subjective health and well-being.
Design/methodology/approach
Adult males (n = 13,891) from an Australian longitudinal men’s health study were classified using latent class analysis. Conditional growth mixture modelling was conducted at three timepoints.
Findings
Three masculinity segments were identified based on masculine norm conformity: traditional self-reliant, traditional bravado and modern status. All segments had likely customer experience of vulnerability. Over time, the likely experience was temporary for the modern status segment but prolonged for the traditional self-reliant and traditional bravado segments. The traditional self-reliant segment had low subjective health and low overall well-being over time.
Practical implications
Practitioners can tailor services to gender norm segments, enabling self-reliant men to provide expertise and use the “Status” norm to reach all masculinity segments.
Originality/value
The study of customer vulnerability in a group usually considered privileged identifies differential temporal experiences based on gender norms. The study confirms customer vulnerability is temporal in nature; customer vulnerability changes over time from likely to actual for self-reliant men.

Abstract
Climate change and the COVID-19 pandemic are complex and have multifaceted effects on countries in an unpredictable and unprecedented manner. While both COVID-19 and the climate crisis share similarities, they also have some notable differences. Being both systemic in nature with knock-on and cascading effects that propagate due to high connectedness of countries, COVID-19, however, presents imminent and directly visible dangers, while the risks from climate change are gradual, cumulative and often distributed dangers. Climate change has more significant medium and long-term impacts which are likely to worsen over time. There is no vaccine for climate change compared to COVID-19. In addition, those most affected by extreme climatic conditions have usually contributed the least to the root causes of the crisis. This is in fact the case of island economies. The chapter thus investigates into the vulnerability and resilience of 38 Small Islands Developing States (SIDs) to both shocks. Adopting a comprehensive conceptual framework and data on various indices from the literature and global databases, we assess the COVID-19 and climate change vulnerabilities of SIDs on multiple fronts. The results first reveal a higher vulnerability across all dimensions for the Pacific islands compared to the other islands in the sample. There is also evidence of a weak correlation between climate change risk and the COVID-19 pandemic confirming our premise that there are marked differences between these two shocks and their impacts on island communities.

Abstract
Developing countries such as the Philippines depend greatly on their natural resources and ecosystem services. However, the capacity to sustain these services is currently being pressured by various environmental hazards, mainly brought about by climate change. Thus, it is imperative to assess the vulnerability of the environment so that effective ecosystem-based management strategy can be developed to improve the sustainability of these services. This chapter presents a geospatial-based method in assessing the vulnerability of watersheds in the country to various environmental hazards. This model is called the Geospatial-Based Regional Environmental Vulnerability Index for Ecosystems and Watersheds, or, in short, the GeoREVIEW model. GeoREVIEW is composed of 21 indicators and each indicator is evaluated using a scale of 1 to 5. A scale of 1 indicates low vulnerability while a scale of 5 signifies high vulnerability. Finally, to determine the vulnerability level of the area, its overall vulnerability point (OVP) is calculated. This model is utilized to evaluate the vulnerability of two significant ecosystems near Metro Manila – the La Mesa Watershed (LMW) and the Mt. Makiling Forest Reserve (MFR). Based on the assessment, it was found that both are already classified as “at risk” levels. However, MFR (OVP=55.24) is found to be less vulnerable than LMW (OVP=62.52). The results from this assessment can be used to improve the management of these areas and can also aid in targeting policy interventions associated with climate change.

Abstract
The importance of the adverse impacts of network degradation has stimulated substantial international research interest in transport network reliability, that is, the ability of degraded transport networks to cope with travel demand. Most of the recent research effort has focused on the reliability of urban passenger transport networks, in terms of the probability that the network will deliver a required standard of performance. This situation is characterised by high levels of congestion, a dense road network, and quantifiable probability of degradation of the network. Outside major urban centres, the situation is very different. The main dominant consideration in transport network infrastructure provision is accessibility - linking urban centres, providing regional coverage, and basic levels of accessibility for the non-urban community and economy. The network is sparse, congestion is not a significant issue, and access to essential community services and to markets is the major driving force underlying network development. In this context, the vulnerability of the network is perhaps more important than ‘reliability’. This paper develops the concept of network vulnerability. It begins by reviewing the current state of research into network reliability, then proposes extensions and adaptations to the reliability concepts that are more appropriate for strategic-level multi-modal transport systems. Several alternative definitions for vulnerability are proposed. The paper also discusses the development of algorithmic and visualisation tools that may be used to identify specific ‘weak spots’ in a network, where failure of some part of the transport infrastructure would have the most serious effects on access to specific locations and on overall system performance. Finally, the paper describes potential applications of network vulnerability concepts, and proposes directions for further research.
