From childhood blue space exposure to adult environmentalism: The role of nature connectedness and nature contact
No full textNature contact in childhood is associated with pro-environmental behaviours (PEB) later in life. While previous literature focused on nature contact in general, the current work specifically explored childhood blue space exposure (coasts, rivers, lakes etc.) and potential mechanisms underlying any relationship with PEBs in adulthood. Cross-sectional data from an Austrian sample representative on age, gender, and region (N = 2,370) were used to test a serial-parallel mediation model linking recalled childhood blue space exposure to self-reported adult PEBs via, first, nature connectedness and, second, recent visits to green and blue spaces. Results supported significant serial mediation, with recalled childhood blue space exposure linked to nature connectedness in adulthood, which was in turn associated with more frequent recent visits to green and blue spaces, which in turn predicted PEB. Significant direct and indirect effects were observed, while controlling for known individualand area-level covariates. Findings highlight the potential importance of childhood blue space exposure as well as life-long nature contact for improving nature connectedness and PEB and add to calls for protecting and maintaining natural water bodies and to improve their safety, as spending time around them in childhood may play a role in fostering PEB and ultimately improving planetary health
Healthy islands
Full text linkSmall Island Developing States (SIDS) form a special setting where nature and (population) health become intimately connected. This chapter outlines the nature of such small states, their development and health challenges, and a common health solution that has been advanced in the Pacific. The Yanuca Declaration established a Healthy Island programme in 1995. It is a specific example of a ‘healthy settings’ approach (Nutbeam, 1996). Healthy Islands form an integrated element of the Pacific development agenda and explicitly pursue a comprehensive agenda at the interface of nature, health, and development. Examples of this agenda are provided in two case studies. First, the WHO-led ‘Healthy Island Recognition’ programme, and second, the commitments among Pacific islands to the Framework Convention on Tobacco Control.</p
A life course approach to public health: why early life matters
No full textThis chapter describes the theoretical and mechanistic basis, and public health implications, of the Developmental Origins of Health and Disease (DOHaD) paradigm, which has emerged from overwhelming epidemiological, clinical, and experimental evidence demonstrating the importance of early life development in influencing an individual’s susceptibility to later life disease risk. DOHaD is underpinned by the evolutionarily conserved processes of developmental plasticity. These enable phenotypic adjustment to match the environment and are effected, in part, by epigenetic mechanisms that modulate patterns of gene expression. This chapter uses obesity and its co-morbidities to illustrate how a life course approach can provide an effective strategy for reducing disease risk and have major policy implications. It focuses on early life as a critical intervention point, and recognizes the importance of taking into consideration the full range of influencial biological, behavioural, and contextual factors that operate across the life course.</p
Environmental assessment and health impact assessment
No full textHIA and EA are approaches and processes that support better, healthier, and more sustainable policy development and decisionmaking. When undertaken well, and when valued and applied, they can also help to support better, more informed, transparent and democratic policy development and decision- making processes. However, they are not a panacea; rather, they constitute one important piece of the policy development and decision- making puzzle. Public health practitioners need to increase their knowledge and understanding of EA and HIA. They should improve their links with EA and HIA specialists. They also need to proactively and consistently undertake and commission assessments of health either within EA or as stand alone HIAs. Public health practitioners would also do well to oversee and scrutinize the scope of work for, and the findings of, EAs and HIAs that are commissioned and undertaken by others in the localities in which they work. By doing so, public health practitioners can help to advance the agenda of improving health for all by acting on the upstream determinants of health and bringing together key actors across society
The healthy settings approach: healthy cities and environmental health indicators
Full text link‘Healthy Cities’ is a global movement in urban health that grew from a Canadian initiative in the mid-1980s to a World Health Organization programme. Healthy Cities are characterized by a strong commitment to values such as sustainability, solidarity, justice, and participation embedded in a vision that embraces ecological and community perspectives. The movement comes in different manifestations around the world; this chapter focuses mostly on the European evidence base and discusses efforts that have been made over three decades to establish validated sets of indicators to measure and assess urban health and Healthy Cities. True to the nature of the movement, indicators are both socioecological and biomedical, qualitative, and quantitative. This presents challenges to validity and applicability across urban environments.</p
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Macrophage-derived extracellular vesicles as carriers of alarmins and their potential involvement in bone homeostasis
No full textExtracellular vesicles are a heterogeneous group of cell-derived membranous structures, which facilitate intercellular communication. Recent studies have highlighted the importance of extracellular vesicles in bone homeostasis, as mediators of crosstalk between different bone-resident cells. Osteoblasts and osteoclasts are capable of releasing various types of extracellular vesicles that promote both osteogenesis, as well as, osteoclastogenesis, maintaining bone homeostasis. However, the contribution of immune cell-derived extracellular vesicles in bone homeostasis remains largely unknown. Recent proteomic studies showed that alarmins are abundantly present in/on macrophage-derived EVs. In this review we will describe these alarmins in the context of bone matrix regulation and discuss the potential contribution macrophage-derived EVs may have in this process
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
