This chapter opens with a discussion naturally ignited fires and fire adaptations, which have evolved over millions of years. It then considers the role people have played over time in manipulating fire regimes, both locally and on a broad scale. Examples from diverse biomes such as the savannas and grasslands of South Africa and Madagascar, the forests of northern Europe and the grasslands and forests of North America provide evidence of the interactions between climate and human-set ignitions. The studies of the systems include analysis of a diverse range of evidence, including sediments, documents, and field evidence, analyzed using models that focus on patterns and processes of fire regimes under differing climates and human activities. The importance of perceptions of the role of fire is also discussed in terms of using fire for management, with examples of changes in attitude in North America from the 19th to the 21st centuries, which have led from seeing all fires as bad to valuing fire as a management tool. Analysis of the historical importance of human-set and natural fires has been critical to arriving at current management decisions.

Indonesia is the most populous Islamic country and as such is host to a diverse range of Islamic beliefs and practices. Here we examine how the diversity of beliefs and practices among Indonesian Muslims relates to group bonding and parochialism. In particular, we examine the predictive power of two distinct types of group alignment, group identification and identity fusion, among individuals from three Sunni politico-religious groups - a fundamentalist group (PKS), a moderate group (NU), and a control sample of politically unaffiliated citizens. Fundamentalists were more fused to targets than moderates or citizens, but contrary to fusion theory, we found across all groups, that group identification (not fusion) better predicted parochialism, including willingness to carry out extreme pro-group actions. We discuss how religious beliefs and practice impact parochial attitudes, as well as the implications for theoretical models linking fusion to extreme behaviour.

From converts to cooperation: Protestant internationalism, US missionaries and Indian Christians and ‘Professional’ social work between Boston and Bombay (c. 1920–1950)

Abstract The 1920s and 30s were a high phase of liberal missionary internationalism driven especially by American-led visions of the Social Gospel. As the missionary consensus shifted from proselytization to social concerns, the indigenization of missions and the role of the ‘younger churches’ outside of Europe and North America was brought into focus. This article shows how Protestant internationalism pursued a ‘Christian Sociology’ in dialogue with the field’s academic and professional form. Through the case study of settlement sociology and social work schemes by the American Marathi Mission (AMM) in Bombay, the article highlights the intricacies of applying internationalist visions in the field and asks how they were contested and shaped by local conditions and processes. Challenging a simplistic ‘secularization’ narrative, the article then argues that it was the liberal, anti-imperialist drive of the missionary discourse that eventually facilitated an American ‘professional imperialism’ in the development of secular social work in India. Adding local dynamics to the analysis of an internationalist discourse benefits the understanding of both Protestant internationalism and the genesis of Indian social work and shows the value of an integrated global micro-historical approach.

AbstractCalcium is the most abundant mineral in the human body and is central to many physiological processes, including immune system activation and maintenance. Studies continue to reveal the intricacies of calcium signalling within the immune system. Perhaps the most well-understood mechanism of calcium influx into cells is store-operated calcium entry (SOCE), which occurs via calcium release-activated channels (CRACs). SOCE is central to the activation of immune system cells; however, more recent studies have demonstrated the crucial role of other calcium channels, including transient receptor potential (TRP) channels. In this review, we describe the expression and function of TRP channels within the immune system and outline associations with murine models of disease and human conditions. Therefore, highlighting the importance of TRP channels in disease and reviewing potential. The TRP channel family is significant, and its members have a continually growing number of cellular processes. Within the immune system, TRP channels are involved in a diverse range of functions including T and B cell receptor signalling and activation, antigen presentation by dendritic cells, neutrophil and macrophage bactericidal activity, and mast cell degranulation. Not surprisingly, these channels have been linked to many pathological conditions such as inflammatory bowel disease, chronic fatigue syndrome and myalgic encephalomyelitis, atherosclerosis, hypertension and atopy.

Noise Management

Research suggests that non-acoustic factors can have a considerable effect on community attitudes and opinions towards aviation noise and that these can be influenced through processes of communication and engagement. This paper reviews literature from various fields to identify the key elements of effective practice, using them as a lens through which to assess case study noise management actions conducted at European airports. This analysis found that communication and engagement holds significant potential for noise management, but that this remains largely unfulfilled due to such methods being used as an ancillary management activity, rather than as a powerful tool to aid in the design and delivery of noise management actions. A series of recommendations and research priorities are proposed that could shape the future of noise management, including potential changes to European policy that more explicitly advocate for communication and engagement as a noise management tool in its own right.

This article presents a case study describing the contribution of a sport psychology consultant to an ultra-distance runner’s attempt to complete 500 miles (800 kilometers) in 20 days through the deserts of North America. The contribution can be considered in four phases that provide a descriptive framework for the role of a sport psychology consultant: (a) establishing a rapport with the athlete, (b) formulating a psychological profile, (c) evaluating the demands of the athletic pursuit and planning an appropriate mental training program, and (d) ongoing evaluation of progress and crisis intervention.

scholarly journals Charcoal in soils of the Allerød-Younger Dryas transition were the result of natural fires and not necessarily the effect of an extra-terrestrial impact

AbstractDuring the warm Bølling-Allerød interstadial, tree species migrated from their refugia in southern Europe northwards into the area within the present temperate climatic zone. It is evident from high levels of charcoal in fossil records in this region that, especially during the later part of the Bølling-Allerød interstadial, many fires occurred. The start of the Younger Dryas was characterised by rapid and intense cooling and rising water tables, with catastrophic effects on the vegetation. Thermophilous pine trees could not survive the cold Younger Dryas climate. Dead wood provided an abundant source of fuel for intense, large-scale fires seen in many records as a concentration of charcoal particles in so-called ’Usselo-soils’ dated to ca 10,95014C BP. A similar trend in increased charcoal indicating increased burning is seen at many sites across North America at this time and it has been suggested by Firestone et al. (2007) that this was caused by an explosion of extra-terrestrial material over northern North America, causing the Younger Dryas climate cooling and Megafaunal extinction. We argue that there is no need to invoke an extraterrestrial cause to explain the charcoal in the fossilized soils. The volume of forest trees that died as a result of the cold Younger Dryas climate would easily have supplied sufficient fuel for intense, large-scale fires and can be used to account for the concentration of charcoal particles. As soils were no longer covered by dense vegetation, much erosion occurred during the Younger Dryas and therefore, at many places, Usselo soils, rich in charcoal, were preserved under aeolian sand dunes.

WHILE MEDICAL HISTORIANS cannot provide us with accurate statistics concerning the incidence of rickets and scurvy in centuries past, they leave little room for doubt about the high prevalence of these disorders prior to the advent of modern scientific medicine. Thus, Castiglione has written that in the sixteenth century scurvy raged throughout northern Europe, in Scandinavia, on the shores of the Baltic, and in the interior of Germany. It is interesting to note, however, that Jacques Cartier, whose sailors had been ravaged by scurvy, learned in 1536 from the Indians that the malady could be cured by juices of the almeda tree. This was 200 years before James Lind demonstrated the curative effects of lemon juice in his treatise on scurvy published in 1753 and almost 400 years before ascorbic acid, which was isolated by Szent-Gyorgi in 1928, was recognized to be vitamin C by Waugh and King in 1932. Rickets, likewise, was occurring in a large portion of children prior to the discovery of the existence of vitamin D by Hess, Steinbock, and Windaus in 1918, of its therapeutic value by Mellanby in 1919, of the equivalent role of sunlight by Hess in 1921, and of the chemical composition of the vitamins by Windaus in 1922. But 200 years earlier Friedrick Hoffman had the answer to the control of this disease almost in hand. He attached much importance to climatic conditions as a factor in rickets, noting that if anything is specially powerful in producing this affliction, it is a surrounding atmosphere of cold foggy air. He cited as striking evidence of this the famous emporium of England, London, which he found to be specially apt to produce and foster this disease.
