This article asks whether the catastrophic impact of the COVID-19 pandemic justifies new limitations or interventions in copyright law so that UK educational institutions can continue to serve the needs of their students. It describes the existing copyright landscape and suggests ways in which institutions can rely on exceptions in the Copyright, Designs and Patents Act 1988 (CDPA), including fair dealing and the exemption for lending by educational establishments. It then considers the viability of other solutions. It argues that issues caused by the pandemic would not enliven a public interest defence to copyright infringement (to the extent this still exists in UK law) but may be relevant to remedies. It also argues that compulsory licensing, while permissible under international copyright law, would not be a desirable intervention, but that legislative expansion to the existing exceptions, in order to encourage voluntary collective licensing, has a number of attractions. It concludes by observing that the pandemic highlights issues with the prevailing model for academic publishing and asks whether COVID may encourage universities to embrace in-house and open access publishing more swiftly and for an even greater body of material.

Radiologic Evidence

Baseball is one of the most popular sports in the United States, with estimates of 4.8 million children 5 to 14 years of age participating annually in organized and recreational baseball and softball. Interest in and fascination with the sport have grown since the beginning of the 20th century, but it was not until 1965 that the issue of "Little League elbow" raised concern about the safety of the game. Recently, highly publicized catastrophic impact injuries from contact with a ball or bat have raised new safety concerns. These injuries provided the impetus for this review of the safety of baseball for 5- to 14-year-old participants. The discussion focuses principally on baseball, but softball is considered in accord with the availability of relevant literature. This statement mainly concerns injuries during practices and games in organized settings; players and bystanders also can be injured in casual play. The term Little League elbow was used in 1965 to denote radiologic evidence of fragmentation of the medial epicondylar apophysis and osteochondrosis of the head of the radius and capitellum.1,2 Subsequent studies of children 12 years old and younger3,4 have found a substantially lower incidence of abnormalities than originally described.1,2 Early detection and intervention seem to permit the complete resolution of symptoms and underlying structural abnormalities.5 More serious abnormalities become more common after the age of 13 years.6-8 The role that repetitive throwing in 5- to 14-year-old children may play in the evolution of elbow overuse injuries at an older age remains to be determined.

IEC 60870-5-104 is an international standard used for tele-control in electrical engineering and power system applications. It is one of the major principal protocols in SCADA system. Major industrial control vendors use this protocol for monitoring and managing power utility devices. One of the most common attacks which has a catastrophic impact on industrial control systems is the control command injection attack. It happens when an attacker injects false control commands into a control system. This paper presents the IEC 60870-5-104 vulnera-bilities from the perspective of command and information data injection. From the SCADA testbed that we setup, we showed that a success-ful control command injection attack can be implemented by exploiting the vulnerabilities identified earlier.

Catastrophic Impact

Steller's sea cow, a giant sirenian discovered in 1741 and extinct by 1768, is one of the few megafaunal mammal species to have died out during the historical period. The species is traditionally considered to have been exterminated by ‘blitzkrieg’-style direct overharvesting for food, but it has also been proposed that its extinction resulted from a sea urchin population explosion triggered by extirpation of local sea otter populations that eliminated the shallow-water kelps on which sea cows fed. Hunting records from eighteenth century Russian expeditions to the Commander Islands, in conjunction with life-history data extrapolated from dugongs, permit modelling of sea cow extinction dynamics. Sea cows were massively and wastefully overexploited, being hunted at over seven times the sustainable limit, and suggesting that the initial Bering Island sea cow population must have been higher than suggested by previous researchers to allow the species to survive even until 1768. Environmental changes caused by sea otter declines are unlikely to have contributed to this extinction event. This indicates that megafaunal extinctions can be effected by small bands of hunters using pre-industrial technologies, and highlights the catastrophic impact of wastefulness when overexploiting resources mistakenly perceived as ‘infinite’.

Catastrophic Impact

On 12 May 2008 at 2.28 pm Beijing Time, an Ms 8.0 earthquake occurred in the Wenchuan County of Sichuan province, China. The associated fault ruptured over 240 km on the ground surface. The resulting damage was very severe and widespread, with casualties of almost 70,000, another 18,000 missing and 370,000 injured. The New Zealand Society for Earthquake Engineering reconnaissance team observed the effects and the recovery from this massive earthquake. The team studied the damages caused to the natural and the built environment due to fault rupture, seismic shaking, huge landslides and rockfalls. Maximum shaking intensity of MM XI significantly exceeded design intensity of MM VII for the area. Earthquake induced landslides had a major and catastrophic impact on development and infrastructure in this earthquake. Site selection was demonstrated to be critical. Brittle or non-ductile and irregular buildings performed very poorly especially in a seismic overload situation. Well engineered structures and dams performed well. Lifeline facilities were severely damaged, which resulted in interruptions to key transportation routes, inhibited rescue and recovery operations.

Conflicts and wars are associated with Ethiopian monarchs throughout history. It might be assumed that the presence of a monarch in a certain province within the country would assure peace and security. However, the opposite appears to be true for much of the history of Ethiopia. North Šäwa experienced a number of wars, conflicts, and predatory raids when its autonomy and relative peace was disrupted by its subjugation to Emperor Tewodros II in 1855. This was followed by Šäwan resistance, a time labelled as a ‘period of anarchy’ by Šäwan authors. The return of Mǝnilǝk from Mäqdäla to Šäwa in 1865 also caused confrontations among power contenders of Šäwa. The transitional period between the reigns of Emperor Mǝnilǝk and Emperor Ḫaylä Śǝllase was also characterized by similar uncertainties which reached their climax in 1916. In a time of relative peace, the autumn of 1895, Šäwan peasants were forced to feed thousands of soldiers from the southern regions of the country on their way to ʿAdwa. The Battle of Sägäle in October 1916 fought on Šäwan soil had a catastrophic impact on the life of local peasantry that forced the government to promise compensation and rehabilitation, a rare practice at that time. Moreover the region was affected by different forms of intermittent conflicts on religious and ethnic pretexts. Interand intraethnic conflicts arose for both economic and cultural reasons. The article attempts to analyse the impacts of the recurrent wars on the life of north Šäwan peasants from 1855 to 1916.

Various etiologies are attributed to the development of subjective tinnitus, but their inter-relationship with the presence of temporomandibular disorders and depression is still poorly understood. To assess the presence of depressive symptoms in individuals with TMD and subjective tinnitus, assessing the impact on their quality of life. This is a cross-sectional observational descriptive study. We evaluated 44 patients in a public University. For TMD diagnosis as well as assessment of depressive symptoms, the RDC/TMD questionnaire was used. Otolaryngological assessment was conducted by means of pure tone, speech, and immitance audiometry. The “Tinnitus Handicap Inventory” questionnaire was also administered. 84% of the individuals with tinnitus had myofascial pain, with the masseter muscle being the most prevalent area of pain, and 16% exclusively had painful and/or degenerative TMJ changes. Among the patients with myofascial pain, 86,5% had depressive symptoms, while among those without myofascial pain, only 42,8% presented these symptoms. Eleven (11) patients (25%) reported slight impact of tinnitus on quality of life, 15 (34%) mild impact, 7 (16%) moderate, 7 (16%) severe, and 4 (9%) catastrophic impact. There was a positive association between the presence of myofascial pain and depressive symptoms (p=0,02), as the intensity of tinnitus increases and the severity of depressive symptoms (p
