Assessing Engineering Resilience for Systems with Multiple Performance Measures

Recently, efforts to model and assess a system's resilience to disruptions due to environmental and adversarial threats have increased substantially. Researchers have investigated resilience in many disciplines, including sociology, psychology, computer networks, and engineering systems, to name a few. When assessing engineering system resilience, the resilience assessment typically considers a single performance measure, a disruption, a loss of performance, the time required to recover, or a combination of these elements. We define and use a resilient engineered system definition that separates system resilience into platform and mission resilience. Most complex systems have multiple performance measures; this research proposes using multiple objective decision analysis to assess system resilience for systems with multiple performance measures using two distinct methods. The first method quantifies platform resilience and includes resilience and other “ilities” directly in the value hierarchy, while the second method quantifies mission resilience and uses the “ilities” in the calculation of the expected mission performance for every performance measure in the value hierarchy. We illustrate the mission resilience method using a transportation systems‐of‐systems network with varying levels of resilience due to the level of connectivity and autonomy of the vehicles and platform resilience by using a notional military example. Our analysis found that it is necessary to quantify performance in context with specific mission(s) and scenario(s) under specific threat(s) and then use modeling and simulation to help determine the resilience of a system for a given set of conditions. The example demonstrates how incorporating system mission resilience can improve performance for some performance measures while negatively affecting others.     

Critical understandings of child development: the development of a module for a post-qualifying certificate course in child protection studies

This paper explores the dilemmas involved in selecting appropriate theoretical and research material to help social workers in practice. Concentrating on the needs of those working in child care and protection, the paper uses the example of the area of child development knowledge to illustrate a process of presenting theory for practice. Specifically, the focus is on the redevelopment of a child development module for a post-qualifying certificate course in child care and protection that aims to encourage students to make critical use of current research and theory. The paper explains the reasoning behind the choice of attachment theory as the underpinning theoretical framework. It also addresses possible pitfalls in an uncritical use of such theory. The paper finally sets out how the module addresses the need social workers have for a framework to guide intervention in individual cases. The dimensions described are those of individual vulnerability or resilience and factors in the environment that are adverse or protective.     

Civic responsibility in a risk democracy

The National Research Council advocates for what they term a risk democracy, in which risk issues require community decision-making based on dialogue. This essay focuses on the promotion of civic responsibility in a risk democracy. Award-winning public awareness campaigns are analyzed to demonstrate how community partnerships and civic responsibility can improve community resilience. First, the role of a community in an emergency is discussed; second, the current focus of the Department of Homeland Security on prevention rather than preparation as illuminated by interviews with emergency managers is critically examined; and finally, public awareness campaigns are presented to show how personal and civic responsibility can assist in emergency planning and response.

Resilience and Survival: Black Teenage Mothers ‘Looked After’ by the State Tell their Stories About their Experience of Care

‘Looked after’ young people are among the most disadvantaged members of our society. While their disadvantaged status should not be ignored, poor outcomes are often emphasised at the expense of good ones. This article reports a study that adopts the concept of resilience to understand the narratives of the participants’ experience of care and foster care. A total of 15 young mothers, aged 16–19 and mainly from black African backgrounds, were interviewed. Despite lacking a ‘secure base’, informants invested in a sense of moral identity and a source of self‐directedness, which enabled them to move from victim of circumstances to individuals who overcome their circumstances.     

Resilience? Contested meanings and experiences in post-disaster Christchurch,New Zealand

The purpose of this paper is to improve understanding of the relationship between sense of place and community resilience, two concepts described and defined differently reflecting different disciplinary research, policies and practices. We draw on international literature that has focused on the interrelationship between these concepts in the context of natural disasters, as well as the findings of a multidisciplinary project in the post-earthquake Christchurch recovery context. We describe how we developed indicators of resilience linked to sense of place as it relates to home, neighbourhood and the city, including place-based social interaction and the role of scientific and technical information. Through integrating literature with the findings from project interviews and a survey, we offer new ways of considering ‘resilience’ and we discuss the implications of our findings for not just the Christchurch recovery, but for future response and recovery to natural disasters throughout New Zealand.     

The LGBQ Social Climate Matters: Policies,Protests, and Placards and Psychological Well-Being Among LGBQ Emerging Adults

Sexual minority youth, including emerging adults, are at risk for negative health outcomes. Minority stress theory posits that heterosexism can contribute to these outcomes among sexual minorities. Researchers have tested this theory with respect to interpersonal heterosexism; however, little attention has been given to macro-level and environmental forms of heterosexism, especially among lesbian, gay, bisexual, and queer (LGBQ) youth. In this study, we examine the role of objective social climate (LGB state-level policies) and experiential distal and proximal environmental microaggressions on the psychological well-being of LGBQ emerging adults. Furthermore, we examine the role of LGBQ identity salience as a moderating factor on the macro/environmental-heterosexism and well-being relationship. Multivariable linear regression results suggest that living in a state without same-sex marriage laws is associated with greater self-esteem, whereas both distal and proximal environmental microaggressions are risk factors for anxiety and perceived stress. Furthermore, identity salience can ameliorate the effects of distal microaggressions and intensify the effects of proximal microaggressions and same-sex marriage legislation. Implications for practice with sexual minority youth are discussed.     

Looking within the household: a study on gender,food security,and resilience in cocoa-growing communities

Many West African cocoa households experience a ‘lean season’ before the cocoa harvest, leaving them vulnerable to various events and issues which potentially cause stress – most notably food insecurity. This study, relying primarily on qualitative data from Côte d'Ivoire, examines how income allocation and intra-household dynamics affect household resilience during the lean season. Its findings indicate that in contexts in which women and men's income are separate and destined for different purposes in the household, the fact that men's income is often earmarked for individual spending creates particular problems for households in the lean season. Women's empowerment within the household is essential to improving intra-household resource allocation for resilience. In many contexts, this translates into development programmes supporting women to increase their production and ability to control income independently of men. However, a context of individual gendered agricultural production, and gendered spending obligations, such as West Africa, calls for a slightly different approach. Enhancing agricultural productivity is critical, but in addition it is important to encourage co-operation between women and men in households to result in joint decision-making in the interests of the household.     

What if gender became an essential,standard element of Vulnerability Assessments?

Vulnerability Assessments (VAs) can be useful tools for providing key insights for non-government organisations and other development actors, including governments. Not only can they provide an extensive, ‘landscape-wide’ understanding of vulnerability and its underlying causes in a specific context, but this understanding can be jointly owned by all participants. They can thus be used for designing risk reduction and resilience-building measures, programmes, or projects that affect specific groups within a community or the landscape. Beyond that, VAs can provide a platform that promotes interaction among otherwise disconnected stakeholders, as well as the evidence and argumentation for community groups to engage in advocacy with local and municipal/district authorities. This article draws on our combined experience as development practitioners, and considers what we have learnt about the importance of integrating gender issues into VAs.
