The aim of this study is to explore the relevance of scientific production on venture capital using bibliometric and mapping tools.We performed a search in Scopus, involving any document published between 1978 and 2020. We used bibliometric indicators to explore documents production, dispersion, distribution, time of duplication, and annual growth, as Price’s law of scientific literature growth, Lotka’s law, the transient index, and the Bradford model. We also calculated the participation index of the different countries and institutions. Finally, we explored the co-occurrence and thematic networks for the most frequently used terms in venture capital research through bibliometric mapping.A total of 1,230 original articles were collected from the timeframe 1978–2020. The model confirms that Price’s law is not fulfilled. Scientific production was better adjusted to linear growth (r = 0.9290) than exponential (r = 0.9161). Literature on venture capital research has increased its growth in the last 43 years at a rate of 7.9% per year, with a production that doubles its size every 9.1 years. The transience index was 79.91%, which indicates that most of the scientific production is due to a lot of authors with a small number of publications on the research topic. Bradford´s law shows that the scientific production in this area is widely distributed in multiple journals, and Lotka’s law indicates that the author’s distribution is heavily concentrated on small producers. The United States of America (USA) and the University of Pennsylvania present the highest production, contributing 31.22% and 1.63% of the total production of research on venture capital.The venture capital task has undergone a linear growth, with a very high rate of transience, which indicates the presence of numerous authors who sporadically publish on this topic. No evidence of a saturation point was observed in the scientific production analyzed, which makes it possible to conclude that the research in venture capital will continue to be in demand by the scientific community.

AbstractThis review reports the Brazilian history in astrobiology, as well as the first delineation of a vision of the future development of the field in the country, exploring its abundant biodiversity, highly capable human resources and state-of-the-art facilities, reflecting the last few years of stable governmental investments in science, technology and education, all conditions providing good perspectives on continued and steadily growing funding for astrobiology-related research. Brazil is growing steadily and fast in terms of its worldwide economic power, an effect being reflected in different areas of the Brazilian society, including industry, technology, education, social care and scientific production. In the field of astrobiology, the country has had some important landmarks, more intensely after the First Brazilian Workshop on Astrobiology in 2006. The history of astrobiology in Brazil, however, is not so recent and had its first occurrence in 1958. Since then, researchers carried out many individual initiatives across the country in astrobiology-related fields, resulting in an ever growing and expressive scientific production. The number of publications, including articles and theses, has particularly increased in the last decade, but still counting with the effort of researchers working individually. That scenario started to change in 2009, when a formal group of Brazilian researchers working with astrobiology was organized, aiming at congregating the scientific community interested in the subject and to promote the necessary interactions to achieve a multidisciplinary work, receiving facilities and funding from the University de Sao Paulo and other funding agencies.

General Surgery Training

Before 1946, when I completed my training in general surgery, I knew very little about the field that eventually became known as pediatric surgery. I knew that children did not get a fair shake in surgery; that was amply proved during my internship and residency. Surgical patients came from the adult world, and children had a difficult time competing with them. Surgeons in general were frightened of children, and they distrusted the ability of anesthetists to wake children up after putting them to sleep, a position not far from that of many anesthetists. The younger and smaller the patient, the more significant the hazard. I knew, also, that in the United States and in Europe, where some surgery of children was more successfully carried out, it fell usually into one of the specialties, especially orthopedics. In those days there was a need for such specialization in the treatment of diseases that are no longer problems: tuberculosis of the bone, osteomyelitis, and polio. I wish I could say that my knowledge of the sad state of child surgery as I saw it in Philadelphia made me determined to bring about changes for the better. Actually, during the last year of my general surgery training at the Hospital of the University of Pennsylvania, I was invited to become surgeon in chief of the Children's Hospital of Philadelphia. Pediatric surgery was thrust upon me. Nevertheless, I was excited about the chance to make surgery safer for children, and I entered my career with that goal.

In march, 1994, the University of Pennsylvania held a conference to celebrate the opening of the Howard Fast papers at the university's library. To commemorate Fast's remarkable sixty-year career, a group of historians and literary critics gathered to reconsider the intellectual and cultural milieu of the United States in the early years of the Cold War. During the eventful years, from 1945 to 1960, Fast emerged as a leading Communist activist and a major literary figure who achieved great popular success. Fast, an unabashed member of the Communist Party, like many other oppositional writers of the era, clashed with the national security state. He faced harassment, blacklisting, and marginalization for his refusal to cooperate with federal authorities who were committed to silencing cultural and political voices from the Left. Like other stalwarts of the Communist Party, Fast was often doctrinaire. As a reporter for the Daily Worker and an occasional partisan polemicist, Fast was often stiflingly orthodox. But Fast's Communism was a distinctively American variant, mediated by New York's Jewish radicalism, deeply concerned with the American dilemma of racial inequality.

The Impact

OBJECT Recent works have assessed academic output across neurosurgical programs using various analyses of accumulated citations as a proxy for academic activity and productivity. These assessments have emphasized North American neurosurgical training centers and have largely excluded centers outside the United States. Because of the long tradition and level of academic activity in neurosurgery at the University of Toronto, the authors sought to compare that program's publication and citation metrics with those of established programs in the US as documented in the literature. So as to not rely on historical achievements that may be of less relevance, they focused on recent works, that is, those published in the most recent complete 5-year period. METHODS The authors sought to make their data comparable to existing published data from other programs. To this end, they compiled a list of published papers by neurosurgical faculty at the University of Toronto for the period from 2009 through 2013 using the Scopus database. Individual author names were disambiguated; the total numbers of papers and citations were compiled on a yearly basis. They computed a number of indices, including the ih(5)-index (i.e., the number of citations the papers received over a 5-year period), the summed h-index of the current faculty over time, and a number of secondary measures, including the ig(5), ie(5), and i10(5)-indices. They also determined the impact of individual authors in driving the results using Gini coefficients. To address the issue of author ambiguity, which can be problematic in multicenter bibliometric analyses, they have provided a source dataset used to determine the ih(5) index for the Toronto program. RESULTS The University of Toronto Neurosurgery Program had approximately 29 full-time surgically active faculty per year (not including nonneurosurgical faculty) in the 5-year period from 2009 to 2013. These faculty published a total of 1217 papers in these 5 years. The total number of citations from these papers was 13,434. The ih(5)-index at the University of Toronto was 50. CONCLUSIONS On the basis of comparison with published bibliometric data of US programs, the University of Toronto ranks first in terms of number of publications, number of citations, and ih(5)-index among neurosurgical programs in North America and most likely in the world.

Harmful Effects

Abstract: The studies on artificial dyes and their harmful effects on health are still being produced in small quantities, and this lack of theoretical background can cause the contradiction existent among them. The goal of this work was to characterize the scientific production about genetic damages associated with the use of food colorings. In this study a survey was carried out in the Scopus database with the following keywords: food dyes, mutatios and câncer, in the title, summary or keywords of the article, from the period of 2006 to 2015, in the areas of Health and life sciences. After data collection and tabulation, a descriptive statistics analysis was performed. The year with the greatest number of publications was 2013, but the number of articles have not increased over the years (p = 0.0632). Only one author stood out, Shibutani, M. with 5 publications and medicine was the area of knowledge that most published about the subject, with 30.63%. A greater number of original articles were observed (72%) and the journal Food and Chemical Toxicology published more articles in the period studied. Only eleven institutions published three or more articles and the United States was the country with the largest number of publications (62), and the most used language in the studies was English (93%), the indocyanine green dye appeared in a greater number in the studies (20%), followed by curcuminoids (17%). The low number of publications on food colorings associated with cancer demonstrates that more studies should be developed in the area, given the importance to human health, since there is an overuse of these additives in food in general.

O objetivo deste trabalho foi caracterizar a produção científica sobre danos genéticos associados ao uso de corantes alimentares. Neste estudo foi feito um levantamento na base de dados Scopus com as seguintes palavras-chave: food dyes, mutations and câncer, no título, resumo ou palavras-chave do artigo, no período de 2006 a 2015, nas áreas de ciências da saúde e ciências da vida. Após o levantamento e tabulação dos dados foi realizada uma análise de estatística descritiva e análise de correlação de Spearman. O ano com maior número de publicações foi 2013, mas o número de artigos não aumentou ao longo dos anos (p= 0,0632). Apenas um autor se destacou, Shibutani, M. com 5 publicações e medicina foi a área do conhecimento que mais publicou sobre o assunto, com 30,63%. Observou-se um maior número de artigos originais (72%) e o periódico Food and Chemical Toxicology publicou mais artigos no período estudado. Apenas onze instituições publicaram três ou mais artigos e os Estados Unidos foi o país com o maior número de publicações (62), sendo que o idioma mais utilizado nos estudos foi o inglês (93%), o corante verde de indocyanina apareceu em maior número nos estudos (20%), seguido pelos curcuminóides (17%). O baixo número de publicações sobre corantes alimentares associados a câncer demonstra que mais estudos deveriam ser desenvolvidos na área, dada a importância para a saúde humana, uma vez que há um uso excessivo desses aditivos nos alimentos em geral.

This chapter examines why educational leaders and businessmen in the United States thought it was a good idea to establish business schools in the first place. The answer often offered at the time was that American business itself had grown so big and complex by the turn of the twentieth century that a new university-level education was now required for the new world of managerial work. However, the more powerful rationale was that businessmen wanted the social status and cultural cachet that came with a university degree. The chapter then looks at the Wharton School of Finance and Economy at the University of Pennsylvania, which was founded in 1881 and became the first business school in the United States. All of the more than six hundred business schools founded in the nearly century and a half since descend from Wharton.

The Impact

Background The coronavirus disease 2019 (COVID-19) pandemic significantly reduced elective surgery in the United States, but the impact of COVID-19 on acute surgical complaints and acute care surgery is unknown. Study design A retrospective review was performed of all surgical consults at the Hospital of the University of Pennsylvania in the 30 days prior to and 30 days following confirmation of the first COVID-19 patient at the institution. Consults to all divisions within general surgery were included. Results Total surgical consult volume decreased by 43% in the post-COVID-19 period, with a significant reduction in the median daily consult volume from 14 to 8 ( P < .0001). Changes in consult volume by patient location, chief complaint, and surgical division were variable, in aggregate reflecting a disproportionate decrease among less acute surgical complaints. The percentage of consults resulting in surgical intervention remained equal in the 2 periods (31% vs 28%, odds ratio 0.85, 95% CI 0.61-1.21, P = .38) with most but not all operation types decreasing in frequency. The rise in the COVID-19 inpatient census led to increased consultation for vascular access, accommodated at our center by the creation of a new surgical procedures team. Conclusion The COVID-19 pandemic significantly altered the landscape of acute surgical complaints at our large academic hospital. An appreciation of these trends may be helpful to other Departments of Surgery around the country as they deploy staff and allocate resources in the COVID-19 era.

On October 3, 1881, William Henry Rawle, the distinguished Philadelphia lawyer and scholar, addressed students at the University of Pennsylvania Law School hoping to illustrate, ‘in a very general and elementary way,’ the differences between the growth of English and early Pennsylvania jurisprudence. ‘It would have been more interesting and more broadly useful,’ Rawle apologized to his audience, ‘if the attempt could have been extended to embrace the other colonies which afterwards became the United States, for there would have been not only the contrast between the mother country and her colonies, but the contrast between the colonies themselves.’ Rawle was confident that such an examination would have revealed how ‘in some cases, one colony followed or imitated another in its alteration of the law which each had brought over, and how, in others, the law was changed in one colony to suit its needs, all unconscious of similar changes in another.’ ‘Unhappily,’ Rawle explained, ‘this must be the History of the Future for the materials have as yet been sparingly given to the world.’
