Principles and Practice of Structural Equation Modeling (2nd ed.)

Many climate change adaptation efforts aim to address the implications of potential changes in the frequency, intensity, and duration of weather and climate events that affect the risk of extreme impacts on human society That risk is determined not only by the climate and weather events (the hazards) but also by the exposure and vulnerability to these hazards Therefore, effective adaptation and disaster risk management strategies and practices also depend on a rigorous understanding of the dimensions of exposure and vulnerability, as well as a proper assessment of changes in those dimensions This chapter aims to provide that understanding and assessment, by further detailing the determinants of risk as presented in Chapter 1 

The first sections of this chapter elucidate the concepts that are needed to define and understand risk, and show that risk originates from a combination of social processes and their interaction with the environment (Sections 22 and 23), and highlight the role of coping and adaptive capacities (Section 24) The following section (25) describes the different dimensions of vulnerability and exposure as well as trends therein Given that exposure and vulnerability are highly context-specific, this section is by definition limited to a general overview (a more quantitative perspective on trends is provided in Chapter 4) A methodological discussion (Section 26) of approaches to identify and assess risk provides indications of how the dimensions of exposure and vulnerability can be explored in specific contexts, such as adaptation planning, and the central role of risk perception and risk communication The chapter concludes with a cross-cutting discussion of risk accumulation and the nature of disasters

A large amount of studies have been produced on disaster-related issues over the last century of research, yet there continues to be gaps in translating knowledge into action. This paper discusses ...

From knowledge to action: Bridging gaps in disaster risk reduction

Adolescence represents a pivotal stage in the development of positive or negative body image. Many influences exist during the teen years including transitions (eg, puberty) that affect one's body shape, weight status, and appearance. Weight status exists along a spectrum between being obese (ie, where one's body weight is in the 95th percentile for age and gender) to being underweight. Salient influences on body image include the media, which can target adolescents, and peers who help shape beliefs about the perceived body ideal. Internalization of and pressures to conform to these socially prescribed body ideals help to explain associations between weight status and body image. The concepts of fat talk and weight-related bullying during adolescence greatly contribute to an overemphasis on body weight and appearance as well as the development of negative body perceptions and dissatisfaction surrounding specific body parts. This article provides an overview of the significance of adolescent development in shaping body image, the relationship between body image and adolescent weight status, and the consequences of having a negative body image during adolescence (ie, disordered eating, eating disorders, and dysfunctional exercise). Practical implications for promoting a healthy weight status and positive body image among adolescents will be discussed.

Weight status and body image perceptions in adolescents: current perspectives

Despite highly specialised and capable emergency management systems, ordinary citizens are usually first on the scene in an emergency or disaster, and remain long after official services have ceased. Citizens often play vital roles in helping those affected to respond and recover, and can provide invaluable assistance to official agencies. However, in most developed countries, emergency and disaster management relies largely on a workforce of professionals and, to varying degrees, volunteers affiliated with official agencies. Those who work outside of such systems have tended to be viewed as a nuisance or liability, and their efforts are often undervalued. Given increasing disaster risk worldwide due to population growth, urban development and climate change, it is likely that 'informal' volunteers will provide much of the additional surge capacity required to respond to more frequent emergencies and disasters in the future. This paper considers the role of informal volunteers in emergency and disaster management. Definitions of volunteerism are reviewed and it is argued that there is an overemphasis on volunteering within, and for, state and formal organisations. We offer a broader definition of 'informal volunteerism' that recognises the many ways ordinary citizens volunteer their time, knowledge, skills and resources to help others in times of crisis. Two broad types of informal volunteerism are identified - emergent and extending - and the implications for emergency and disaster management are considered. Particular attention is given to increasing 'digital volunteerism' due to the greater accessibility of sophisticated but simple information and communication technologies. Culture and legal liability are identified as key barriers to greater participation of informal volunteers. We argue that more adaptive and inclusive models of emergency and disaster management are needed to harness the capacities and resilience that exist within and across communities.

A review of informal volunteerism in emergencies and disasters: Definition, opportunities and challenges

A growing awareness of the value of indigenous knowledge has prompted calls for its use within disaster risk reduction. The use of indigenous knowledge alongside scientific knowledge is increasingly advocated but there is as yet no clearly developed framework demonstrating how the two may be integrated to reduce community vulnerability to environmental hazards. This paper presents such a framework, using a participatory approach in which relevant indigenous and scientific knowledge may be integrated to reduce a community's vulnerability to environmental hazards. Focusing on small island developing states it presents an analysis of the need for such a framework alongside the difficulties of incorporating indigenous knowledge. This is followed by an explanation of the various processes within the framework, drawing on research completed in Papua New Guinea. This framework is an important first step in identifying how indigenous and scientific knowledge may be integrated to reduce community vulnerability to environmental hazards.

Framework for integrating indigenous and scientific knowledge for disaster risk reduction.

The aim of this review was to develop an empirically supported cognitive behavioural model of compulsive exercise within the context of the eating disorders. A systematic review of the correlates and predictors of compulsive exercise among eating disordered patients identified four key correlates. These were subsequently validated by a second review, incorporating both the clinical and non-clinical as well as the exercise science literatures. A proposed model is presented which is both evidence-based and testable.

Compulsive exercise and eating disorders

Objective
The Compulsive Exercise Test (CET) was developed to assess the primary factors operating in the maintenance of excessive exercise.

Methods
A total of 367 young female exercisers were recruited from University campuses. Across three separate studies, the participants completed either the CET alone, or the CET and other standard self-report measures of excessive exercise and eating psychopathology.

Results
Factor analyses yielded five factors from which a final 24-item, five subscale measure was constructed. The CET demonstrated high internal consistency across the three samples. Supporting the concurrent and convergent validity of the scale, the CET correlated in the expected direction with existing measures of excessive exercise and eating pathology. As expected, the CET explained greater variance in eating pathology than existing measures of excessive exercise.

Discussion
The resulting subscales of the CET are consistent with a cognitive-behavioural maintenance model of excessive exercise and support the multidimensionality of the excessive exercise construct. Further research is required to validate the instrument within a sample of eating disordered women. Copyright © 2011 John Wiley & Sons, Ltd and Eating Disorders Association.

Disordered eating and exercise: Development and preliminary validation of the compulsive exercise test (CET)

Exercise in the eating disorders: terms and definitions.

Objective:
To explore the associations between specific elements of compulsive exercise and both eating-disordered cognitions and eating-disordered behaviors in a nonclinical sample of young women.

Method:
A sample of young women (n = 498) completed self-report measures of eating pathology (The Eating Disorders Examination Questionnaire) and a relatively new measure of Compulsive Exercise Test.

Results:
Specific elements of compulsive exercise were associated with elevated levels of eating-disordered cognitions and increased frequency of eating-disordered behaviors.

Discussion:
These results support a multifunctional conceptualization of compulsive exercise, suggesting that some of the functionality of compulsive exercise may be akin to other forms of purging, and further supporting the notion of a possible functional equivalence between compulsive exercise and specific eating-disordered behaviors in terms of affect regulation. © 2010 by Wiley Periodicals, Inc.
