The spionid polychaete Boccardia proboscidea Hartman, 1940 is a tube-dweller and shell/stone-borer widely occurring in temperate waters across the world and considered invasive in many areas. It was originally described from California, USA, and later reported from Pacific Canada, the Asian Pacific, Australia, New Zealand, Argentina, South Africa, and northern Europe. The Bayesian inference analysis of sequence data of three gene fragments (836 bp in total) of the mitochondrial 16S rDNA, nuclear 28S rDNA, and Histone 3 has shown that individuals from the Pacific coasts of Canada and the USA, Argentina, Australia, South Africa, the United Kingdom, and Mediterranean France were genetically very similar (maximal average p-distance value, 0.49%, was between 16S rDNA sequences). We consider these individuals to be conspecific and report the earliest records of B. proboscidea from the UK and a possible first Mediterranean record in the Gulf of Lion. The high 16S haplotype diversity of B. proboscidea detected in the north-eastern Pacific suggests a native distribution for the species in the northern Pacific and subsequent introductions through human activities to other parts of the world. The histories of these introductions are reviewed and the hypotheses about times and places of introductions are updated.

Abstract Background The World Health Organization (WHO) declared severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) a pandemic on March 11, 2020. This report takes a closer look at the cases, fatalities, and recoveries in different regions of the world with details regarding the geographic scale of SARS-CoV-2 spread, risks, and the subsequent impact on the countries affected. Also, this report discusses some effective measures that were carried out by some countries that helped them to mitigate the pandemic and flatten the curve of COVID-19 spread as early as possible. Methods Our research was conducted via an electronic literature review on PubMed, Google Scholar, and MedLine Plus. Data were then collected from peer-reviewed articles that included applicable keywords and published between January 1, 2020, and June 9, 2020 Results The rapid spread of infection has impacted over 200 countries and territories to date. As of June 9, 2020, there were 7,039,918 confirmed cases and 404,396 deaths globally. The USA is the North American country with the highest number of confirmed COVID 19 cases with 1,993,560. In South America, total confirmed cases in Brazil are 691,758. The most affected country in the African region is South Africa with 50,879. In Europe, the Russian Federation top with 485,253 confirmed cases. China with 84,638 is still the Western Pacific country with the most confirmed COVID 19 cases. India had 266,598 total confirmed cases and Australia reported 7,265 confirmed cases. Fatalities recorded similar patterns regionally except in Europe where the UK recorded the highest number of fatalities with 40,597 deaths and Iran had the highest number of fatalities with 5,957 cases in Asia. The goal of the practice “slowing the spread” is to prevent hospital systems from being strained beyond their capacity, thus resulting in less mortality. Countries yet to see the peak would benefit substantially by implementing aggressive social distancing, self-isolation, closure of schools and other institutions, encouraging working from home, and/or placing hard limits on the size of crowds at events. Confirmed cases of COVID-19 globally, as of June 9, 2020. Confirmed fatalities due to COVID-19 globally, as of June 9, 2020. Conclusion As the number of cases increases, an immediate need to “flatten the curve” is essential to avoid catastrophic overwhelming of hospital systems across the affected countries.

The 1939 invasion of Finland by the Soviet Union attracted more than just journalists to the frigid north. Thousands of volunteers around the world rallied under the Finnish flag, willing to risk their lives for a foreign country. Over ten thousand arrived before the end of the war, with more on their way, coming from Hungary and Estonia, Canada and the USA, Sweden and the UK. Were they all ardent anticommunists or did they have other motives? This article seeks to answer that question, utilising Finnish and British archives as well as contemporary research into war volunteering. The origins and motives of the volunteers are examined, revealing that their motives ran a wide gamut, including such reasons as anti-communism, linguistic fraternity and spirit of adventure, to name a few.

The Common Tasks for Assessment (CTA) was a new assessment programme that was introduced in 2002 in South Africa for all Grade 9 learners. The purpose of this paper is to articulate some concerns around the use of contextualised assessment activities in the CTA. The study reported here was carried out in 2003. Data for the study was generated from lesson observations and interviews with the participant teachers and groups of learners. It is argued that although the intentions behind the design of the CTA are well meaning and noble, there are in fact some learners who may be unintentionally disadvantaged by the design of the CTA which uses an extended context as a source for all the assessment tasks. In this paper two unintended consequences of using ‘real life’ contexts are identified and the implications of these are discussed, by linking the observations to research carried out in the UK and the USA.

There are now widespread signs that activity in the world economy has begun to recover steadily from the pause in growth apparent at the beginning of 1996. Output rose by 0.6 per cent in the North American economies in the third quarter of last year and by 0.8 per cent in Europe. Business and consumer sentiment has improved gradually in recent months in most of the major economies. We expect world economic growth to pick up further over the course of this year as the contractionary effects from the downturn in world trade and prolonged inventory adjustment come to an end and as the effects from a more relaxed monetary stance begin to outweigh those from ongoing fiscal consolidation. Recent currency movements should help to stimulate external demand in Germany, France and Japan, but may act to constrain growth within the UK, Italy and the US. For both this year and 1998 we expect growth of around 2½ per cent per annum in the OECD economies.

AbstractRapakivi granites were in use during the Middle Ages in Finland. Their most spectacular use, however, was for structures built in St Petersburg between 1760 and 1917. Remarkable examples are the majestic and slender Alexander Column and the 112 columns of St Isaac's Cathedral. All Rapakivi granite was extracted from the Wiborg Rapakivi granite batholith in several quarries around the municipality of Virolahti in SE Finland (old Russia). Today, the 1640 Ma-old Wiborg batholith is the most important area for natural stone production in Finland and in the Leningrad region, Russian Federation. The main quarried stone varieties of Rapakivi granite (Baltic Brown, Baltic Green, Carmen Red, Karelia Red, Eagle Red and Balmoral Red) are regularly produced in large quantities in Finland for the global stone market due to the stone's unique qualities. Examples of applications in Rapakivi granite from Finland can be found in the USA, China, South Africa, the UK, Italy, Austria, Ireland, Spain and Germany as well as in Scandinavia and Russia. There are also quarries near Vyborg, the Russian Federation: Vozrozhdenie and Ala-Noskua.

In this paper, we draw on our own cross-cultural experience of engaging with different incarnations of the medical and health humanities (MHH) in the UK and South Africa to reflect on what is distinct and the same about MHH in these locations. MHH spaces, whether departments, programmes or networks, have espoused a common critique of biomedical dualism and reductionism, a celebration of qualitative evidence and the value of visual and performative arts for their research, therapeutic and transformative social potential. However, there have also been differences, and importantly a different ‘identity’ among some leading South African scholars and practitioners, who have felt that if MHH were to speak from the South as opposed to the North, they would say something quite different. We seek to contextualise our personal reflections on the development of the field in South Africa over recent years within wider debates about MHH in the context of South African academia and practice, drawing in part on interviews conducted by one of the authors with South African researchers and practitioners and our own reflections as ‘Northerners’ in the ‘South’.

Oor ’n wye front word besorgdheid uitgespreek oor die stagnering en kwynende getallegroei van hoofstroom-reformatoriese kerke in Suid-Afrika. Die besorgdheid word egter ook uitgespreek dat predikante en kerke in hulle ywer om kerklike vernuwing teweeg te bring, soveel kompromieë maak dat die kerk sy eie aard as heilge volk van God in die wêreld verloor. Daar is ’n internasionale tendens te bespeur by reformatoriese kerke, in Suid-Afrika, Noord Amerika, Australië, Nederland, Duitsland en die Verenige Koninkryk om die na-binne-gerigtheid van kerke om te draai om werklik missionêre kerke te kan wees. Daar is ook tekens van ’n groeiende ontwakende passie om die onbereikte taalgroepe tot by die uithoeke van die aarde te bereik met die evangelie. Daar is oor ’n wye front lewendige debatte aan die gang wat vra vir ’n herevaluering van oorgeërfde ekklesiologiese tradisies en gebruike en ’n herbesinning oor Bybelse beginsels. In die lig van hierdie ontwikkelings is die doel van hierdie artikel om Nuwe-Testamentiese beginsels op te som en te onderstreep en as boustene aan te bied om die profiel van ’n missionêre kerk te skets. Grave concerns are expressed about the decline of mainline reformed churches in South Africa, especially the Reformed Churches in South Africa. At the same time fears are expressed that efforts to facilitate renewal in churches in order to become healthy and more effective missional churches, are making too many compromises with the gospel, so that the church is in danger of losing its very character as God’s holy people in the world. There is also an international phenomenon of reformed and evangelical type churches in North America, the Netherlands, Germany, the UK and Australia endeavouring to outgrow their ingrown vision and become part of God’s mission to reach unreached people groups in every corner of the world. There are lively debates on reviewing and rethinking inherited ecclesiological theological traditions and practices in churches. This article endeavours to gather basic building bricks by summarising and emphasising the most basic New Testament principles for outlining the profile of a missional church.

BackgroundUveitis appears to be less prevalent in the UK compared with other parts of the world and studies characterising the disease in the UK are lacking. The objectives of this retrospective study were to describe acute and recurrent cases presenting for management of uveitis in a referral hospital on the North West of England and compare the signalment of horses presenting with uveitis with the equine hospital population during the same period.MethodsMedical records of horses presented to the referral Equine Hospital, University of Liverpool with signs of uveitis between 2008 and 2018 were reviewed and clinical details extracted.ResultsSeventy horses presented with uveitis; 33 were classified as acute and 37 as recurrent cases. Sixteen of the horses were affected bilaterally. More bilateral cases were classified as recurrent than acute (P=0.04). No differences in age or sex were noted between acute and recurrent cases, or between cases and the general hospital population. Warmbloods and Appaloosas were over-represented when compared with the general hospital population (P<0.001). Twenty-one horses (30 per cent, 95 per cent CI 20.5 to 41.4) underwent surgery for the control of the uveitis. Fourteen of the 70 horses (20.0 per cent, 95 per cent CI 12.3 to 30.8) underwent enucleation.ConclusionWhile relatively uncommon in the UK, uveitis can affect horses from a relatively young age. The disease appears to have a relatively higher frequency than expected in Warmbloods and Appaloosas. It is more likely that a recurrent case will have both eyes affected.
