O conceito de "destruição criativa" foi apresentado por Schumpeter (1950) e mudou de forma significativa como os economistas consideram os benefícios do processo de concorrência nas economias baseadas na livre empresa. É formado de duas palavras, uma positiva "criativa" e outra negativa "destruição". A parte "positiva" diz respeito ao fato de que empreendedores, usualmente entrantes, inovam criando (daí o termo "criativa") novos produtos e serviços ou novas formas de produzi-los em um determinado tipo de negócio. Estes novos produtos ou serviços, ao ampliar o leque de escolha, incrementam o bem-estar dos consumidores. Algumas vezes tais novidades podem ser tão superiores aos prod...
A Série Universitária foi desenvolvida pelo Senac São Paulo com o intuito de preparar profissionais para o mercado de trabalho. Os títulos abrangem diversas áreas, abordando desde conhecimentos teóricos e práticos adequados às exigências profissionais até a formação ética e sólida. Aplicações móveis com serviços cognitivos é um guia introdutório que ensina o passo a passo para compreender a dinâmica entre o que são modelos de aprendizado de máquina e o que é chamado hoje de inteligência artificial; ou ainda, nos termos de mercado, os serviços cognitivos e sua implementação em ambiente web mobile. O livro também serve como introdução a assuntos novos no cotidiano das massas, como modelos de aprendizado profundo, arquitetura de nuvem, arquitetura de redes neurais profundas, tecnologias generativas e inovação e tecnologia; tudo isso com uma pitada de ironia, humor ácido e ética.
This dissertation consists of three essays that examine various problems in financial economics. Chapter 1 fills in a gap in the IPO literature by documenting a close connection between IPO underpricing and the long-term underperformance of IPOs. Firms going public in periods of low underpricing do not underperform in the long run, while firms going public in high underpricing periods do. Furthermore, IPOs in later stages of high underpricing periods underperform even relative to their offer prices, which suggests that many of the most "underpriced" IPOs are in fact priced above fundamental value. This result is unlikely to be explained by differences in risk, or to be driven by a peso probl...
A well-known obstetrician and gynecolegist, at one time the most prominent doctor in the fight to repeal abortion laws, now, after years of philosophical and moral struggle, believes that abortion on request in wrong.

"Brazil was the leading world producer of gold and of diamonds between the mid-18th century and the mid-19th century. At the present time, it is the leading world producer of iron ore, tin and niobium, and an important producer of manganese, aluminium, silicon, tantalum, rare earths, graphite, magnesite and countless other ores.....Brazil is the leading world producer of tourmaline (of all colors), of quartz (colorless, rutilated, amethyst and agate), of beryl (aquamarine, morganite and heliodore, and the second ranking world producer of emerald), of topaz (imperial, blue and colorless), alexandrite, euclase, phenakite and many others" INTRODUCTION.
The conditions and characteristics of correctional facilities - overcrowded with rapid population turnover, often in old and poorly ventilated structures, a spatially concentrated pattern of releases and admissions in low-income communities of color, and a health care system that is siloed from community public health - accelerates transmission of the novel coronavirus (SARS-CoV-2) responsible for COVID-19. Such conditions increase the risk of coming into contact with the virus for incarcerated people, correctional staff, and their families and communities. Relative to the general public, moreover, incarcerated individuals have a higher prevalence of chronic health conditions such as asthma,...
This book offers an analysis of Putin's approval ratings from the fall of the USSR to the present day. It considers contemporary materials, statistics and a discourse analysis to assess how Putin's approval ratings have stayed so high despite the current economic turndown. Through a comparative analysis with Yeltsin's time in office, the author demonstrates that higher levels of security, a better standard of living, increasingly assertive foreign policy and greater centralization of power led to positive approval ratings for Putin—absent characteristics during Yeltsin’s terms—and fostered 'positive national self-esteem' in Russia, a national sentiment that has persisted through current economic difficulties. Recommended reading for academics and students of Russian studies in the field of International Relations, Foreign Policy and Comparative Politics.
This volume provides the latest research on circulating tumor cells aimed for cancer researchers, scientists, and molecular oncologists. It presents the basic concepts behind circulating tumor cells (CTCs), metastatic biology, and potential applications as to how CTCs can be used in diagnostic biomarkers. CTCs are cells that have detached from the primary tumor and circulate in the bloodstream. Such cells may become "seeds" for the growth of additional tumors. The field of analysis surrounding cancer metastasis has been steadily growing, and CTCs provide effective biomarkers that can be examined in peripheral blood through a minimally invasive “liquid biopsy” procedure. CTCs offer several exciting applications, not only as markers of disease progression but also as biomarkers of monitoring response to therapy and companion diagnostics for novel anticancer drug development. In recent years there has been rapid growth and worldwide developments on CTCs, which span both the basic sciences and biomedical engineering fields.
Carcara Photo Art's Brazilian Photography collection presents Jurandy Valença. In his own words: “I create images, I don’t create photographs. My production comes from everyday references. The main issue in my work is time. The memory.”
He messes up games. He draws on the wall. He won't take turns, and he won't share. That little kid is nothing but a big pest!
