The natural rivers and their flood areas are among the most complex and diverse ecosystems in the world. Traditional structural solutions in river training works are focused on basic requirements as flood protection, littoral zone protection, river bed protection, providing the space for economic development. In this study a method of anticipated assessment of certain physical impact of designed river training works is presented, perceived as global effect of river bed artificialization. The method mainly serves to compare the various possible solutions of river training works, based on the ?artificialization parameter? also named ?global impact GI?.

‘Man still bears in his bodily frame the indelible stamp of his lowly origin.’ On topics ranging from intelligent design and climate change to the politics of gender and race, the evolutionary writings of Charles Darwin occupy a pivotal position in contemporary public debate. This volume brings together the key chapters of his most important and accessible books, including the Journal of Researches on the Beagle voyage (1845), the Origin of Species (1871), and the Descent of Man, along with the full text of his delightful autobiography. They are accompanied by generous selections of responses from Darwin’s nineteenth-century readers from across the world. More than anything, they give a keen sense of the controversial nature of Darwin’s ideas, and his position within Victorian debates about man’s place in nature. The wide-ranging introduction by James A. Secord, Director of the Darwin Correspondence Project, explores the global impact and origins of Darwin’s work and the reasons for its unparalleled significance today.

Abstract This paper explores the figurative expression of emotion in Gija, a non-Pama-Nyungan language from the East Kimberley in Western Australia. As in many Australian languages, Gija displays a large number of metaphors of emotion where miscellaneous body parts – frequently, the belly – contribute to the figurative representation of emotions. In addition, in Gija certain verbal constructions describe the experience of emotion via metaphors of physical impact or damage. This second profile of metaphors is far less widespread, in Australia and elsewhere in the world, and has also attracted far fewer descriptions. This article explores both types of metaphors in turn. Body-based metaphors will be discussed first, and we will highlight the specificity of Gija in this respect, so as to offer data that can be compared to other languages, in Australia and elsewhere. The second part of the article will present verbal metaphors. Given that this phenomenon is not yet very well undersood, this account aims to take a first step into documenting a previously unexplored domain in the language thereby contributing to the broader typology that this issue forms a part of. Throughout the text, we also endeavour to connect the discussion of metaphors with local representations and understanding of emotions.

Introduction: The COVID-19 pandemic has strained the healthcare systems across the world but its impact on acute stroke care is just being elucidated. We hypothesized a major global impact of COVID-19 not only on stroke volumes but also on thrombectomy practice. Methods: A 19-item questionnaire survey aimed to identify the changes in stroke volumes and treatment practices seen during COVID-19 pandemic was designed using Qualtrics software. It was sent to stroke and neuro-interventional physicians around the world who are part of the executive committee of a global coalition, Mission Thrombectomy 2020 (MT2020) between April 5 th to May 15 th , 2020. Results: There were 113 responses across 25 countries. Globally there was a median 33% decrease in stroke admissions and a 25% decrease in mechanical thrombectomy (MT) procedures during COVID-19 pandemic compared to immediately preceding months (Figure 1A-B). This overall median decrease was despite a median increase in stroke volume in 4 European countries which diverted all stroke patients to only a few selected centers during the pandemic. The intubation policy during the pandemic for patients undergoing MT was highly variable across participating centers: 44% preferred intubating all patients, including 25% centers that changed their policy to preferred-intubation (PI) vs 27% centers that switched to preferred-conscious-sedation (PCS). There was no significant difference in rate of COVID-19 infection between PI vs PCS (p=0.6) or if intubation policy was changed in either direction (p=1). Low-volume (<10 stroke/month) compared with high-volume stroke centers (>20 strokes/month) are less likely to have neurointerventional suite specific written personal protective equipment protocols (74% vs 88%) and if present, these centers are more likely to report them to be inadequate (58% vs 92%). Conclusion: Our data provides a comprehensive snapshot of the impact on acute stroke care observed worldwide during the pandemic.

This chapter describes the worrisome trend of resistance development in antibacterial agents with exponential increases in resistance to the most effective classes of antibiotics. Described by the World Health Organization as a major global health security threat, the annual deaths from drug-resistant infection are projected to increase from 700,000 to 10 million by 2050. This chapter outlines the impact of antimicrobial resistance in humanitarian settings and provides practical approaches which can be used by organizations and health providers.

South Asia (Bangladesh, India, and Pakistan) has produced some of the greatest Islamic thinkers, such as Shah Wali Allah (sometimes also spelled Waliullah; 1702–1763) who is considered one of the originators of pan-Islamism, Rahmatullah Kairanwi (1818–1892), Muhammad Iqbal (1877–1938), Syed Abul A’la Mawdudi (also spelled Maududi; 1903–1979), and Abul Hasan Ali Hasani Nadwi (1914–1999), who have all played a pivotal role in shaping political Islam and have all had global impact. Islamism is intertwined with Muslim antisemitism. Some of the greatest Islamist movements have their bases in South Asia, such as Tablīghi Jamā’at—the largest Sunni Muslim revivalist (daw’a) movement in the world—and Jamā’at-i-Islāmi—a prototype of political Islam in South Asia. The region is home to some of the most important institutions of Islamic theological studies: Darul Ulūm Deoband, the alleged source of ideological inspiration to the Taliban, and Nadwātu’l-’Ulamā and Firangi Mahal, whose curricula are followed by seminaries across the world attended by South Asian Muslims in their diaspora. Some of the most popular Muslim televangelists have come from South Asia, such as Israr Ahmed (1932–2010) and Zakir Naik (b. 1965). This paper gives an introductory overview of antisemitism in the Muslim intellectual discourse in South Asia.

Non-western scholars usually face a dilemma if they want to pursue an international scholarly career: On the one hand, mastering western media theories is mandatory for taking part in international forums and exchanging experiences with people from different parts of the world; on the other hand, these theories are, in many aspects, foreign to their cultural backgrounds and, in many cases, seem inadequate for describing their own societies. My personal contribution to the debate arises from the fact that, although having some experience in participating in Anglophonic communication meetings and publishing in international academic vehicles, I never had first-hand experience, either as a student or as a professor, in American or European universities. In consequence, I was exposed to Western Anglophonic theories without being socialized in a scholarly environment in which they are taken as ‘natural’. Based on this experience, I contend that the global impact of western theories cannot be explained only by their intrinsic merits, but as the result of the socialization of scholars from all parts on the world in western educational institutions, and the networks built around them.

AbstractThe aim of the following study was to compare a few methods of river regulations and indicate the one which fully meets technical regulative standard and concurrently ensures protection of the watercourse ecosystem. According to the sustainable development rules it is of the most importance in every human activity to compromise between developmental and environmental needs of current and future generations. Therefore, both technical criteria related to flood safety and environmental ones were taken into consideration in the analysis. Field study was conducted in vegetation stage between 2008 and 2014 in small and medium lowland watercourses in Lower Silesia. The research comprised of measurements and descriptions of selected technical and environmental elements of a complex system of the watercourse river bed. Basing on obtained results a multicriterial assessment of the effects of the works was conducted. In order to assess the results an Analytic Hierarchy Process (AHP) was used in the study. It facilitated the creation of linear ranking of river beds and indicate the most optimal solution in terms of sustainable development. Such methods have not been applied in solving problems connected with river regulation. That’s why this study aims also at checking the utility of this method in decision making in both planning and regulation works realization. Results of the study indicate high usefulness of AHP method in the decision-making process.

Headache disorders are the dominant cause of neurological disability in the world and the most common reason for neurological referral in any country studied. Yet for much of the first half the twentieth century, research was mired in peripheral mechanistic sideshows. Migraine, the most common disabling primary headache disorder, has been established as primarily a brain problem, with important advances in classification, treatment, and biological understanding. Cluster headache, perhaps the most severe pain experience of humans, has found its nidus in the diencephalon; treatments are evolving and biology being unravelled. Contributions to headache disorders resonate across humanity, so important work here has a global impact for good.
