Multicriteria Decision Framework for Cybersecurity Risk Assessment and Management

Risk assessors and managers face many difficult challenges related to novel cyber systems. Among these challenges are the constantly changing nature of cyber systems caused by technical advances, their distribution across the physical, information, and sociocognitive domains, and the complex network structures often including thousands of nodes. Here, we review probabilistic and risk-based decision-making techniques applied to cyber systems and conclude that existing approaches typically do not address all components of the risk assessment triplet (threat, vulnerability, consequence) and lack the ability to integrate across multiple domains of cyber systems to provide guidance for enhancing cybersecurity. We present a decision-analysis-based approach that quantifies threat, vulnerability, and consequences through a set of criteria designed to assess the overall utility of cybersecurity management alternatives. The proposed framework bridges the gap between risk assessment and risk management, allowing an analyst to ensure a structured and transparent process of selecting risk management alternatives. The use of this technique is illustrated for a hypothetical, but realistic, case study exemplifying the process of evaluating and ranking five cybersecurity enhancement strategies. The approach presented does not necessarily eliminate biases and subjectivity necessary for selecting countermeasures, but provides justifiable methods for selecting risk management actions consistent with stakeholder and decisionmaker values and technical data.     

Efficiency of Even Separation of Parallel Elements with Variable Contest Intensity

The article considers strategic defense and attack of a system that can be separated into parallel elements. The defender distributes its resource between separation and protecting the elements from outside attacks. The vulnerability of each element is determined by an attacker‐defender contest success function, which depends on a contest intensity that may increase or decrease through the separation process. The article determines criteria of separation efficiency for systems without performance redundancy and 1‐out‐of‐N and Q‐out‐of‐N systems with performance redundancy. For the systems with performance redundancy the cases of expected damage proportional to the probability that the demand is not met, and expected damage proportional to the unsupplied demand, are considered.     

Beyond 'Vulnerability': An Ecological Model Approach to Conceptualizing Risk of Sexual Violence against People with Learning Difficulties

This paper presents an ecological model approach to conceptualizingrisk of sexual violence against people with learning difficulties,which takes account of the complex social processes involvedin the creation of risk. The concept ‘vulnerability’,often assumed to be a risk-creating characteristic of peoplewith learning difficulties, is too simplistic to take accountof all the processes involved in the formation of risk of sexualviolence. Risk is influenced by personal attributes, self-defenceskills, environments and socio-cultural factors. These riskfactors are closely interlinked and constantly interact withone another. The ecological model provides a tool for examiningthe impact that interactions between individuals and socialenvironments have on an individual’s learning and thedevelopment opportunities that have the potential to increaseself-defence skills.

The E.S.S.E. Group Model

Social work practitioners today are having to deal with ever-increasing numbers of families falling into the at risk category. At the same time, the issues and problems facing these family units are often overwhelming and challenging to resolve. The E.S.S.E. Group Model, outlined in this article, is a new research based approach that was designed to address the most relevant concerns facing families today. It is a unique program that combines family life education within a support group framework. Initially, the model was developed for several school districts in the midwest. Counseling personnel had identified a need for a parent training program that would elicit higher levels of participation. The E.S.S.E. Model accomplishes that goal through its structured yet individualized curriculum along with its parallel and conjoint group set-up. The specific content and process guidelines of this new approach make it easy for clinicians to duplicate in a wide variety of settings. One of the model's curriculums is outlined in detail in this article. Readers will find that the E.S.S.E. program serves as an excellent example of the type of group intervention needed today to help revitalize at-risk families.     

Alternative approaches to researching social capital: A comment on van Deth's measuring social capital

This paper responds to van Deth's overview of empirical research on social capital and the difficulties of measuring the concept. We entirely agree with many of the problems that he identifies with the dominant mode of enquiry to date: namely survey and polling methods of attitudinal data. We are sure there are ways of improving on such quantitative methods although we are of the view that qualitative research is especially helpful for exploring the processes of social capital formation and the relationship between networks and norms so crucial to Putnam's use of the concept. Briefly, we discuss our own qualititive work involving intensive interviews with 120 activists drawn from a Citizens Audit of Britain. We address the importance of pre-existing trust and informal processes of mobilization, the significance of experiences of group involvement for generating norms of trust as well as distrust and the extent to which evaluations of such experiences influence wider views of participation and democracy in Britain. In sum, we totally endorse van Deth's call for the greater use of 'multi-methods and multi-level srategies' in empirical research by extending his plea to consider the valuable role of qualitative methods in the study of social capital.     

Lottery marketing in Québec and social deprivation: excessive exposure,insufficient protection?

In 2008, the Institut national de santé publique du Québec (INSPQ) undertook a research programme on lotteries. The preliminary qualitative exploratory component enabled us to observe the diversity and ubiquity of lottery advertising to which the vast majority of the population is exposed, including minors and non-players. The aim of a second component was to better comprehend the relationships between exposure to lottery marketing, lottery purchasing habits, attitudes towards gambling, and socio-economic vulnerability indicators. The study's data was collected by a polling firm from a representative sample of adults in the Québec population (n = 2001). Our survey revealed significant links between exposure, gambling behaviour and certain socio-economic indicators: for example, individuals with lower levels of education more often play the lotteries and spend the most on them. In addition, a greater number of people who are less educated and from a low-income household considered that lottery advertising was very or excessively present in their daily lives and that the amount of advertising has increased in recent years. From the perspective of creating healthy environments and protecting vulnerable populations, legislative measures to control the quantity, location and contents of gambling marketing would be promising preventive measures.     

The Power of the Vulnerable Body

Abstract

Through a critical Agambean reading of aging Finland's care deficit, I argue that the human body is politically powerful in its “bare” vulnerability. Even in feminist care theory, however, the neediness of the body is barely recognized as political. This is somewhat paradoxical, given that the vulnerable body is discursively deeply feminized. Thus, through a deconstructive reading of feminist care theory and Joan Tronto's (1993 Tronto, J. 1993. Moral Boundaries: A Political Argument for an Ethic of Care. New York and London: Routledge. [Google Scholar]) ethics of care in particular, I argue for a new political understanding of care, defined as a corporeal relation. In this conception, the political dimensions of care are no longer understood in terms of work or the moral dispositions enabled by caring, as the existing literature largely suggests. Rather, the political relevance of care is seen as departing from that which makes the work of care an absolute necessity: namely, the needy body that belongs to each and every one of us. Through its neediness, the vulnerable body exposes itself as a constant opening of the political, the recognition of which also leads to an alternative type of ethics.     

Encountering the ageing body in modernity: fear,vulnerability and “contamination”

This paper attempts to understand the exclusion of ageing people within contemporary society through developing a model around the notion of the “encounter with the ageing body”. It is divided into three parts. In the first, I develop a model of the encounter through combining Sara Ahmed’s notion of “affective economies” with Shildrick’s theory of the encounter with the “vulnerable self”. I argue that the fear of ageing becomes embodied within the encounter with the ageing body. Specifically, the fear is vulnerability: within the encounter, the youthful self is forced into the recognition of his/her own vulnerability. Modernity requires that this be disavowed, with the ageing body banished to the margins through sequestration to foreclose the possibility of a repeat. In the second section, I discuss the nature of vulnerability within modernity. I explore two approaches to this: in the first, the vulnerability is to the threat of death, which has become particularly problematic within modernity; in the second, the vulnerability is the loss of subjectivity resulting from the ageing body’s failure to correspond to constructions of the ideal body within contemporary capitalism. In the final section, I evaluate whether recent social shifts promise a brighter future for ageing people, arguing that although the situation is not black and white, there is, nevertheless, unfortunately currently relatively limited potential for real change for older people.
