The following paper is an advance of the innovation project that has been undertaken by the Departments of Education and History of the Open University of Madrid; an institution that since its creation has managed all its activity by means of an online methodology. The main goal of the project is to establish the appropriate strategies to maximize the efficiency of the digital resources, with special attention to audiovisual material.Our work was articulated in two phases: a first one consisting of the implementation of audiovisual material in the virtual classrooms, and the second one, focused on analysing the degree of satisfaction that students showed with these resources.In general, the preliminary results show a positive perception of the students regarding the use of videos in their learning process. However, they also show interesting nuances, first because it is the students themselves who, from their experience, reject the videos as the main learning tool and, second, because clear differences are detected depending on the degree considered: a demand for much more pragmatic and short-term content in the degree of Education, and more speculative and medium-long-term in the History area.

At the end of 2019, coronavirus disease (COVID-19) outbreak is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV2). Worldwide researchers and physician try to explore the mechanisms of damage induced by virus, they focus on the short-term and long-term immune-mediated consequences induced by the virus infection. Every day discover a new pathological condition induced by virus and new symptoms and disease may occur after recovery from disease. Our case report is 41 years old, Indian lady who presented to our primary health care centre complaining of multiple small hand joints pain, both elbows and knees pain with swelling of them and prolonged morning stiffness, diagnosed seropositive rheumatoid arthritis (RA) (arthritis, positive rheumatoid factor (RF), and X-ray changes) after 1 month recovery from COVID-19 infection. She did not have any joint pain and she had negative RF before COVID-19 infection with no family history of RA.

The Business Cycle

This paper deals with a debate between Hawtrey, Hicks and Keynes concerning the capacity of the central bank to influence the short-term and the long-term rates of interest. Both Hawtrey and Keynes considered the central bank’s ability to influence short-term rates of interest. However, they do not put the same emphasis on the study of the long-term rates of interest. According to Keynes, long-term rates are influenced by future expected short-term rates (1930, 1936), whereas for Hawtrey (1932, 1937, 1938), long-term rates are more dependent on the business cycle. Short-term rates do not have much effect on long-term rates according to Hawtrey. In 1939, Hicks enters the controversy, giving credit to both Hawtrey’s and Keynes’s theories, and also introducing limits to the operations of arbitrage. He thus presented a nuanced view.

This chapter focuses on the history of democratization since the late eighteenth century. It introduces the concepts of ‘waves’ (trends) and ‘conjunctures’ (briefer turmoils) and delineates the major developments in this respect. In this way, the major long-term and short-term factors leading to the emergence and breakdowns of democracies are also highlighted. The first long wave occurred during the period 1776–1914, followed by the first positive conjuncture in 1918–19, the second long wave (with some intermittent turbulences) in 1945–88, and the latest conjuncture in 1989–90. The chapter identifies the main ingredients to democratization throughout history, namely: republicanism, representation, and political equality. It concludes by considering some of the current perspectives and dangers for the future of democracy.

Introduction Prophylactic appendicectomy is performed prior to military, polar and space expeditions to prevent acute appendicitis in the field. However, the risk–benefit ratio of prophylactic surgery is controversial. This study aimed to systematically review the evidence for prophylactic appendicectomy. It is supplemented by a clinical example of prophylactic surgery resulting in life-threatening complications. Methods A systematic review was performed using MEDLINE® and the Cochrane Central Register of Controlled Trials. Keyword variants of ‘prophylaxis’ and ‘appendicectomy’ were combined to identify potential papers for inclusion. Papers related to prophylactic appendicectomy risks and benefits were reviewed. Results Overall, 511 papers were identified, with 37 papers satisfying the inclusion criteria. Nine reported outcomes after incidental appendicectomy during concurrent surgical procedures. No papers focused explicitly on prophylactic appendicectomy in asymptomatic patients. The clinical example outlined acute obstruction secondary to adhesions from a prophylactic appendicectomy. Complications after elective appendicectomy versus the natural history of acute appendicitis in scenarios such as polar expeditions or covert operations suggest prophylactic appendicectomy may be appropriate prior to extreme situations. Nevertheless, the long-term risk of adhesion related complications render prophylactic appendicectomy feasible only when the short-term risk of acute appendicitis outweighs the long-term risks of surgery. Conclusions Prophylactic appendicectomy is rarely performed and not without risk. This is the first documented evidence of long-term complications following prophylactic appendicectomy. Surgery should be considered on an individual basis by balancing the risks of acute appendicitis in the field with the potential consequences of an otherwise unnecessary surgical procedure in a healthy patient.

Presented here is the case of a 21-year-old man, with a family history of unilateral renal agenesis, who presented with obstruction of his solitary functioning right kidney. Initially thought to be secondary to an obturator fossa hernia on endoscopic and retrograde pyelography assessment, diagnosis of obstruction secondary to an aberrant middle rectal artery was determined at laparotomy and division of this vessel relieved the patient’s obstruction without any short-term or long-term complications. To the best of the authors’ knowledge, this is the first reported case in the literature of hydroureteronephrosis secondary to an aberrant middle rectal artery.

In Poland, there were 176 cases of prefrontal leucotomy performed by Moniz’s method between 1947 and 1951. There were also several cases in which alternative psychosurgical techniques were used: prefrontal topectomy by Bilikiewicz and colleagues, and prefrontal topischemia by Ziemnowicz. This article analyses the following: publications by Choróbski, who performed lobotomy in Poland, and by Korzeniowski, who assessed its short-term results; a report by Bornsztajn, who reviewed general results of the method; and clinical research by Broszkiewicz and by Konieczyńska, who assessed Polish patients in terms of long-term results of lobotomy. Negative clinical evaluation of lobotomy led to its abandonment in Poland, a decision strengthened by a regulation that forbade lobotomy in the USSR and impacted Polish psychiatry.

Background Short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) and short-lasting unilateral neuralgiform headache attacks with cranial autonomic symptoms (SUNA) are two rare headache syndromes classified broadly as Trigeminal Autonomic Cephalalgias (TACs). Methods Here, 65 SUNCT (37 males) and 37 SUNA (18 males) patients were studied to describe their clinical manifestations and responses to treatment. Results Pain was almost always unilateral and side-locked. There were three types of attack: Single stabs, stab groups, and a saw-tooth pattern, with some patients experiencing a mixture of two types. As to cranial autonomic symptoms, SUNA patients mainly had lacrimation (41%) and ptosis (40%). Most cases of the two syndromes had attack triggers, and the most common triggers were touching, chewing, or eating for SUNCT, and chewing/eating and touching for SUNA. More than half of each group had a personal or family history of migraine that resulted in more likely photophobia, phonophobia and persistent pain between attacks. For short-term prevention, both syndromes were highly responsive to intravenous lidocaine by infusion; for long-term prevention, lamotrigine and topiramate were effective for SUNCT, and lamotrigine and gabapentin were efficacious in preventing SUNA attacks. A randomized placebo-controlled cross-over trial of topiramate in SUNCT using an N-of-1 design demonstrated it to be an effective treatment in line with clinical experience. Conclusions SUNCT and SUNA are rare primary headache disorders that are distinct and very often tractable to medical therapy.

Because ice shelves respond to climatic forcing over a range of time scales, from years to millennia, an understanding of their long-term history is critically needed for predicting their future evolution. We present the first detailed reconstruction of the Larsen C Ice Shelf (LCIS), eastern Antarctic Peninsula (AP), based on data from sediment cores recovered from below and in front of the ice shelf. Sedimentologic and chronologic information reveals that the grounding line (GL) of an expanded AP ice sheet had started its retreat from the midshelf prior to 17.7 ± 0.53 calibrated (cal.) kyr B.P., with the calving line following ~6 k.y. later. The GL had reached the inner shelf as early as 9.83 ± 0.85 cal. kyr B.P. Since ca. 7.3 ka, the ice shelf has undergone two phases of retreat but without collapse, indicating that the climatic limit of LCIS stability was not breached during the Holocene. Future collapse of the LCIS would therefore confirm that the magnitudes of both ice loss along the eastern AP and underlying climatic forcing are unprecedented during the past 11.5 k.y.

In the past decade or so, various models have emerged concerning the study of culture and marketing in regards to consumerism, of which Geert Hofstede's dimensional model of national culture has been applied to various areas of global branding and advertising, and the underlying theories of consumer behavior. Hofstede's model has been used to explain differences regarding the concepts of self, personality and identity, which in turn explain variations in branding strategy and communications. Thus, the purpose of this chapter is to address the psychology of consumerism in business and marketing from the macro and micro behaviors of Hofstede's cultural consumers. The chapter emphasizes Hofstede's fifth cultural dimension, long-term versus short-term orientation regarding marketing. In so doing, both macro and micro paradigms on the psychology of consumers' behaviors will be covered in relation to marketing, as well as a brief history of marketing and the marketing field.

As representatives of the West in China, to use Isabel Crook’s words, the long-term residents were active participants in the PRC’s ‘people-to-people diplomacy’ (or ‘friendship diplomacy’) which, like its Soviet counterpart, was directed towards influencing foreign public opinion, especially in the West. In her book A History of China’s Foreign Propaganda 1949–1966, PRC journalist and author Xi Shaoying saw the long-term residents, along with short-term invited ‘friends of China’, as playing an integral role in the government’s ‘foreign propaganda work’. In the West, the long-termers’ most contentious activity was their support for the PRC against their own governments.
