Recent zoonotic disease emergences emphasize the importance of studying wildlife parasite communities. As wild hosts frequently harbour diverse parasite species, understanding the drivers of multiple infection patterns in free-ranging hosts is critical for elucidating the ecological and epidemiological dynamics of parasite communities. In this study, we analysed co-infection patterns in European roe deer (Capreolus capreolus) inhabiting a fragmented rural landscape in southwestern France. Using data from 130 samples of GPS-tracked deer, we examined the influence of proximity to livestock, host activity levels, age, sex and between-parasite interactions on the presence of 11 parasitic taxa. Hierarchical modelling of species communities (HMSC) revealed that proximity to livestock significantly increased the likelihood of infection with orofecally transmitted parasites (Toxoplasma gondii, gastrointestinal parasites). Sex and age were other key predictors, with males and juveniles exhibiting a higher frequency of parasite presence, likely influenced by hormonal and immune system differences. Activity levels showed distinct age-related effects, with higher activity levels being positively associated with increased parasite prevalence in yearlings, but not in adults. In contrast, parasite association patterns within individual hosts were weak, suggesting minimal interactions between parasite species. Our findings highlight the interplay between exposure and susceptibility in shaping co-infection patterns and underscore the value of hierarchical modelling approaches in multi-parasite systems.
The chapter will help you to be able to explain what PTSD is and how it typically presents, including the nature of trauma memories and associated re-experiencing, describe and use evidence-based CBT protocols for PTSD, choose and use appropriate formulation models for CBT for PTSD, describe the importance of reprocessing in any treatment plan, develop a treatment plan for CBT for PTSD, and take account of comorbidity in managing CBT for PTSD.
The chapter will help you to be able to describe the different techniques available in CBT, consider the purpose of any given technique in relation to the maintenance cycles it interrupts, and tailor interventions to individual patients, considering their unique strengths and needs.
This chapter provides a comprehensive overview of cognitive behavioural therapy (CBT) for generalised anxiety disorder (GAD). Several evidence-based CBT protocols for the treatment of GAD are presented and their clinical implications discussed using case examples. These protocols are 1) the applied relaxation protocol, 2) the Penn protocol, 3) the mastery of your anxiety and worry protocol, 4) the intolerance of uncertainty protocol, and 5) the Beckian cognitive protocol. In the chapter we present a theoretical overview of GAD from the perspective of each these protocols. The difference between adaptive and excessive worry is also discussed and how this distinction is important when it comes to identifying key maintenance factors of GAD and what needs to happen in treatment. The aim of this chapter is to help the clinician understand different theoretical accounts of GAD and why and how to use therapeutic techniques such as formulations, behavioural experiments, imaginal exposure, applied relaxation and cognitive restructuring when treating GAD. Furthermore, how to address co-morbidity with other mental or physical conditions and why working within the scientist-practitioner model is important when it comes to developing treatment plans for GAD treatment.
The chapter will help you to be able to describe the development of CBT approaches for anxiety disorders, explain how the four key factors influence the level of perceived threat from a cognitive perspective, and consider the comparative purposes of habituation, cognitive restructuring and behavioural experiments in treating anxiety disorders
In order to understand how urban disaster risk changes, it is essential to understand how cities change. This chapter argues that cities are continually evolving entities whose past and present dynamics provide insights into future trends and possibilities. The chapter first reviews global trends in disaster losses, along with well-established definitions and frameworks about disaster risk. It explains why these are inadequate for understanding how a city’s disaster risk changes over time. It then proposes a simple conceptual framework, the Urban Risk Dynamics framework, to help guide empirical study of evolving disaster risk in any city. The framework is based on several premises: that local geography, or landscape, is vital to understanding urban disaster risk; that cities must be understood as economic entities; and that technological change is a key driver of urban change. The chapter then introduces and justifies the selection of the six case studies to be analyzed using the framework in Chapters 3–5.
Virtual reality (VR) may improve psychological treatments for psychotic disorders. We investigated the effects of VR-based cognitive behavior therapy for paranoid ideation (VR-CBTp) compared to standard CBTp.
Methods
We conducted a pragmatic, single-blind, randomized clinical trial in seven mental health centers across the Netherlands and Belgium. A total of 98 participants with a psychotic spectrum disorder and paranoid ideation were randomized to a maximum of 16 sessions of VR-CBTp (n = 48) or CBTp (n = 50). The primary outcome was momentary paranoia, measured with the experience sampling method (ESM) at posttreatment. Secondary measures, assessed at baseline, posttreatment, and 3-month follow-up, included symptoms (paranoia, hallucination, depression, cognition, and anxiety related), social functioning, self-esteem, and schemes.
Results
Both groups showed reductions in momentary paranoia between baseline and posttreatment (n = 56, b = −15.0, effect size [ES] = 0.65), but those were greater for VR-CBT (interaction b = 8.3, ES = 0.62). Reductions remained at follow-up (n = 50, b = −10.7, ES = 0.57) but not the interaction. Limited ESM compliance resulted in data loss; however, secondary paranoia measures did confirm improvements (ES range = 0.66–1.15, n = 78–81), but not the interaction. Both groups improved in symptoms, self-esteem, and social functioning. Interaction effects in favor of VR-CBTp were found for safety behavior, depression, and self-esteem at posttreatment, and self-esteem and anxiety at follow-up. For VR-CBTp, 37.5% did not complete treatment; for CBTp, this was 24.0%. Completers, on average, received 12.7 (VR-CBTp: standard deviation [SD] = 3.9) and 15.1 (CBTp: SD = 2.5) sessions.
Conclusions
Both CBTp and VR-CBTp are efficacious treatments for paranoid ideation, but VR-CBTp may be somewhat more effective. Limitations concern missing primary outcome data and a lower sample size than anticipated.
As we progress through this part and the next, you will be introduced to the different ways in which epidemiologists go about analysing the factors that are associated with people becoming ill or getting better. Each of these has a role to play in building up our knowledge about what influences human health. Our objective here is to provide an overview of the range of techniques that are available and to develop your understanding of which of these might be more appropriate in any given situation. One way to think about these techniques is as a set of tools for tackling a range of problems, much as a carpenter has a box full of tools for tackling different aspects of building a house. No one tool is useful in every situation, and some are more useful at certain stages of the construction process than others. Some even have features that make them useful in a variety of situations. Of course, context is everything, so even when a tool might not look like it’s the ‘right’ one in a particular situation, if the results are robust and reliable then that might be all that matters.
This chapter reviews how climate change is projected to affect the frequency, severity and/or spatial distribution of tropical cyclones, severe storms that generate tornadoes, and floods; the factors that influence people’s exposure and vulnerability to such events; adaptation options for reducing displacement risks; and, common characteristics of migration and displacement across all categories of extreme weather events. We then focus on specific types of extreme weather and provide more detailed analyses and case studies of migration and displacement events associated with tropical cyclones, tornadoes, and floods.
Chapter 5 explores James’s interest in the relationship between the bicycle and authorial publicity through a close reading of his tale about two cycling journalists, ‘The Papers’. During the 1890s, the bicycle’s fashionable status and prominent appearance in debates about female exhibitionism associated it with questions about the role of the press and the public figure. Due to its potential for physical comedy, cycling also features in what I call the literatures of exposure: the detective story, romantic comedy, and the illustrated newspaper. As I argue, the bicycle’s attachment to the physical ‘figure’ makes it a troubling metaphoric resource in ‘The Papers’, which satirizes the celebrity’s ‘eagerness to figure’ by drawing attention to the authorial work of ‘figuring’ in which the journalists are constantly engaged, and to the creation of the author as a public figure. This chapter also glances at how later writers have employed the bicycle to speculate about Henry James himself. Hemingway’s euphemistic reference to ‘Henry’s bicycle’ in The Sun Also Rises – an allusion to James’s rumoured castration – is one of several portrayals of the author as a cyclist, which draw upon the bicycle’s connotations with exposure to trope James’s aversion to publicity.
This chapter covers generalized anxiety disorder, panic disorder, specific phobia, social anxiety disorder, agoraphobia, separation anxiety disorder, and selective mutism. Based on a review using the new criteria for empirically supported treatments, there is strong research support for: (a) exposure therapies for specific phobias, (b) cognitive and behavioral therapies for generalized anxiety disorder, (c) cognitive-behavioral therapy for panic disorder, and (d) cognitive-behavioral therapy for social anxiety disorder. The two primary components of treatment include exposure and addressing cognitive biases. Each of these components is broken down into additional parts. A sidebar also discusses acceptance and commitment therapy.
This study longitudinally modeled home language exposure patterns of US Spanish–English bilingual children between the ages of 4 and 12. Participants were 280 Spanish–English bilinguals (95% Hispanic, 52% female) who were followed for up to 5 years using a cross-sequential longitudinal design. Multilevel linear regression models were used to estimate language exposure trajectories across four home language sources (adults, peers, electronic media and literacy activities) and three language modes (Spanish-only, English-only and bilingual). Results demonstrated that Spanish interactions with both adults and peers declined as children aged, while bilingual interactions showed a distinct increase over time. Conversely, media exposure and engagement in literacy activities increased over time, irrespective of the language used. Children’s age of first English exposure and current school English exposure also influenced language contact and use in the home. These findings approximate an 8-year exposure trajectory across a continuum of bilingual experiences.
This chapter introduces the reader to the topic studied in the book, factual misinformation and its appeal in war. It poses the main research question of who believes in wartime misinformation and how people know what is happening in war. It then outlines the book’s central argument about the role of proximity and exposure to the fighting in constraining public misperceptions in conflict, and the methods and types of evidence used to test it. After clarifying some key concepts used in the book, it finally closes with a sketch of the manuscript’s main implications and an outline of its structure and contents.
This chapter provides the tools to compute catastrophe (CAT) risk, which represents a compound measure of the likelihood and magnitude of adverse consequences affecting structures, individuals, and valuable assets. The process consists of first establishing an inventory of assets (here real or simulated) exposed to potential hazards (exposure module). Estimating the expected damage resulting from a given hazard load (according to Chapter 2) is the second crucial step in the assessment process (vulnerability module). The application of damage functions to exposure data forms the basis for calculating loss estimates (loss module). To ensure consistency across perils, the mean damage ratio is used as the main measure for damage footprints D(x,y), with the final loss footprints simply expressed as L(x,y) = D(x,y) × ν(x,y), where ν(x,y) represents the exposure footprint. Damage functions are provided for various hazard loads: blasts (explosions and asteroid impacts), earthquakes, floods, hail, landslides, volcanic eruptions, and wind.
This study investigates the referential forms children use to introduce characters in Swedish, in a cross-sectional sample of oral narratives by 100 Turkish/Swedish bilinguals aged 4 to 7 and in a longitudinal sample from age 4 to 6 (N = 10). We analysed development with age and how language proficiency (expressive vocabulary) and exposure affect children’s use of referring expressions, with a focus on referential appropriateness. In addition, a qualitative analysis of the characteristics of high- and low-performing children was carried out. The results show significant effects of age and language proficiency, but not of language exposure on appropriate use of referring expressions. At age 7, 69% of the characters were introduced with an indefinite NP. The Turkish/Swedish bilinguals were found to lag behind in their use of indefinite NPs in comparison to Swedish-speaking children investigated in previous studies, with little crosslinguistic influence from L1 Turkish.
Now in its fourth edition, this textbook provides a chronological account of first language acquisition, showing how young children acquire language in their conversational interactions with adult speakers. It draws on diary records and experimental studies from leaders in the field to document different stages and different aspects of what children master. Successive chapters detail infants' and young children's progression from attending to adult faces, gaze, and hand motions, to their first attempts at communicating with gaze and gesture, then adding words and constructions. It comprehensively covers the acquisition of the core areas of language – phonetics and phonology, lexicon, grammar and sentence structure, and meaning – as well as how children acquire discourse and conversational skills. This edition includes new sections on how children build 'common ground' with adults and other children, individual differences in children's language development, how they collaborate with adults in constructing utterances, and how they qualify beliefs.
Poor air quality can both trigger and aggravate lung and heart conditions, as well as affecting child development. It can even lead to neurological and mental health problems. However, the precise mechanisms by which air pollution affect human health are not well understood.
Aims
To promote interdisciplinary dialogue and better research based on a critical summary of evidence on air quality and health, with an emphasis on mental health, and to do so with a special focus on bioaerosols as a common but neglected air constituent.
Method
A rapid narrative review and interdisciplinary expert consultation, as is recommended for a complex and rapidly changing field of research.
Results
The research methods used to assess exposures and outcomes vary across different fields of study, resulting in a disconnect in bioaerosol and health research. We make recommendations to enhance the evidence base by standardising measures of exposure to both particulate matter in general and bioaerosols specifically. We present methods for assessing mental health and ideal designs. There is less research on bioaerosols, and we provide specific ways of measuring exposure to these. We suggest research designs for investigating causal mechanisms as important intermediate steps before undertaking larger-scale and definitive studies.
Conclusions
We propose methods for exposure and outcome measurement, as well as optimal research designs to inform the development of standards for undertaking and reporting research and for future policy.
Factual misinformation is spread in conflict zones around the world, often with dire consequences. But when is this misinformation actually believed, and when is it not? Seeing is Disbelieving examines the appeal and limits of dangerous misinformation in war, and is the go-to text for understanding false beliefs and their impact in modern armed conflict. Daniel Silverman extends the burgeoning study of factual misinformation, conspiracy theories, and fake news in social and political life into a crucial new domain, while providing a powerful new argument about the limits of misinformation in high-stakes situations. Rich evidence from the US drone campaign in Pakistan, the counterinsurgency against ISIL in Iraq, and the Syrian civil war provide the backdrop for practical lessons in promoting peace, fighting wars, managing conflict, and countering misinformation more effectively.
The language continuum is defined by the dimensions of language ability (from language talent to language disorder) and bilingual language proficiency (from monolingual to multilingual) in this chapter. Although the terms “language ability” and “proficiency” are often used interchangeably in the literature, we systematically differentiate these two dimensions in order to explain variations in speakers from different linguistic backgrounds. Cross-linguistic data are presented to strengthen this argument. The differentiation of these two language dimensions is important for professionals to prevent the over- and underdiagnosis of children who come from language minority groups or exhibit bilingual language disorder. A discussion of similarities in language acquisition between typically developing monolingual and bilingual first language speakers and between monolingual and bilingual children with developmental language disorder is included to highlight common features along the language dimensions. Within-subject approaches and different measures of assessment are described to support the classification of children from diverse linguistic environments.
This chapter describes how the quality and quantity of language input affects both children’s language ability and their cognitive control development. A nuanced exploration of the distinctions between input and intake as well as between input and exposure points to a complex pattern of interactions among these components and children’s communicative skills. The interactions among parental input, language environment, and the child’s age, as well as communicative abilities are bidirectional and affect children’s cognitive control skills, particularly working memory and interference control. The dynamic nature of caregiver – child interactions is also reflected in the manner parents adjust their language input based on their children’s communicative abilities. Parents of children with superior language skills used more elaborated language than did the parents of children with language delay, but those who participated in parental intervention increased the language and cognitive stimulation of their children.
