153-514: Interpretations of the LPIA vary, with some researchers arguing it represented one continuous glacial event and others concluding that as many as twenty-five separate ice sheets across Gondwana developed, waxed, and waned independently and diachronously over the course of the Carboniferous and Permian, with the distribution of ice centres shifting as Gondwana drifted and its position relative to

306-613: A Portuguese colony until 1808, when the capital of the empire was transferred from Lisbon to Rio de Janeiro . In 1815, the colony was elevated to the rank of kingdom upon the formation of the United Kingdom of Portugal, Brazil and the Algarves . Independence was achieved in 1822 with the creation of the Empire of Brazil , a unitary state governed under a constitutional monarchy and a parliamentary system . The ratification of

459-617: A colony . In 1815, to justify continuing to live in Brazil, where the royal court had thrived for six years, the Crown established the United Kingdom of Portugal, Brazil and the Algarves , thus creating a pluricontinental transatlantic monarchic state. However, the leadership in Portugal, resentful of the new status of its larger colony, continued to demand the return of the court to Lisbon (see Liberal Revolution of 1820 ). In 1821, acceding to

612-489: A democratic federal republic . Due to its rich culture and history, the country ranks thirteenth in the world by number of UNESCO World Heritage Sites . Brazil is a regional and middle power that is an emerging power and a major non-NATO ally of the United States . Categorized as a developing country , Brazil is considered an advanced emerging economy , having the one of the-largest GDP in

765-410: A research question is identified. A gap in the current literature, as identified by a researcher, then engenders a research question. The research question may be parallel to the hypothesis . The hypothesis is the supposition to be tested. The researcher(s) collects data to test the hypothesis. The researcher(s) then analyzes and interprets the data via a variety of statistical methods, engaging in what

918-569: A "public domain", that of "humanity". This idea gained prevalence as a result of Western colonial history and ignores alternative conceptions of knowledge circulation. For instance, most indigenous communities consider that access to certain information proper to the group should be determined by relationships. There is alleged to be a double standard in the Western knowledge system. On the one hand, "digital right management" used to restrict access to personal information on social networking platforms

1071-872: A charismatic figure who could represent a moderate face of power, during this period a series of localized rebellions took place, such as the Cabanagem in Grão-Pará , the Malê Revolt in Salvador, the Balaiada ( Maranhão ), the Sabinada ( Bahia ), and the Ragamuffin War , which began in Rio Grande do Sul and was supported by Giuseppe Garibaldi . These emerged from the provinces' dissatisfaction with

1224-431: A colony. The Brazilians refused to yield, and Prince Pedro decided to stand with them, declaring the country's independence from Portugal on 7 September 1822. A month later, Prince Pedro was declared the first Emperor of Brazil , with the royal title of Dom Pedro I , resulting in the founding of the Empire of Brazil . The Brazilian War of Independence , which had already begun along this process, spread through

1377-730: A cyclicity of approximately 1.2 million years. This is most similar to the early part of the Late Cenozoic Ice Age, from the Oligocene to the Pliocene , before the formation of the Arctic ice cap , suggesting the climate of this episode of time was relatively warm for an icehouse period. Evidence from the Middle Permian Lucaogou Formation of Xinjiang , China indicates that the climate of the time

1530-837: A dense and complex system of rivers, one of the world's most extensive, with eight major drainage basins, all of which drain into the Atlantic. Major rivers include the Amazon (the world's second-longest river and the largest in terms of volume of water), the Paraná and its major tributary the Iguaçu (which includes the Iguazu Falls ), the Negro , São Francisco , Xingu , Madeira and Tapajós rivers. The wildlife of Brazil comprises all naturally occurring animals , plants , and fungi in

1683-504: A full dictatorship with the promulgation of the Fifth Institutional Act in 1968. Oppression was not limited to those who resorted to guerrilla tactics to fight the regime, but also reached institutional opponents, artists, journalists and other members of civil society, inside and outside the country through the infamous " Operation Condor ". Like other brutal authoritarian regimes , due to an economic boom, known as

1836-532: A greenhouse as the Permian progressed. Obliquity nodes that triggered glacial expansion and increased tropical precipitation before 285.1 Mya became linked to intervals of marine anoxia and increased terrestrial aridification after this point, a turning point signifying the icehouse-greenhouse transition. Increased lacustrine methane emissions acted as a positive feedback enhancing warming. The LPIA finally ended for good around 255 Ma. Researcher Research

1989-427: A higher altitude. In the interior northeast, seasonal rainfall is even more extreme. South of Bahia, near the coasts, and more southerly most of the state of São Paulo, the distribution of rainfall changes, with rain falling throughout the year. The south enjoys subtropical conditions, with cool winters and average annual temperatures not exceeding 18 °C (64.4 °F); winter frosts and snowfall are not rare in

2142-523: A military one , did civilians take power, remaining there until October 1930. In relation to its foreign policy, the country in this first republican period maintained a relative balance characterized by a success in resolving border disputes with neighboring countries, only broken by the Acre War (1899–1902) and its involvement in World War I (1914–1918), followed by a failed attempt to exert

2295-576: A negative δ18O excursion. Ice sheets retreated southward across Central Africa and in the Karoo Basin. A regional glaciation spanning the latest Sakmarian and the Artinskian, known as P2, occurred in Australia amidst this global pulse of net warming and deglaciation. This massive deglaciation during the late Sakmarian and Artinskian is sometimes considered to be the end of the LPIA proper, with

2448-467: A non-empirical task is the prototyping of a new drug using a differentiated application of existing knowledge; another is the development of a business process in the form of a flow chart and texts where all the ingredients are from established knowledge. Much of cosmological research is theoretical in nature. Mathematics research does not rely on externally available data; rather, it seeks to prove theorems about mathematical objects . Research ethics

2601-408: A novel interpretation of previous results. In analytical work, there are typically some new (for example) mathematical results produced or a new way of approaching an existing problem. In some subjects which do not typically carry out experimentation or analysis of this kind, the originality is in the particular way existing understanding is changed or re-interpreted based on the outcome of the work of

2754-420: A number of oceanic archipelagos , such as Fernando de Noronha , Rocas Atoll , Saint Peter and Paul Rocks , and Trindade and Martim Vaz . Its size, relief, climate, and natural resources make Brazil geographically diverse. Including its Atlantic islands, Brazil lies between latitudes 6°N and 34°S , and longitudes 28° and 74°W . Brazil is the fifth largest country in the world, and third largest in

2907-410: A political crisis, after having returned to power by election in 1950. Several brief interim governments followed Vargas's suicide. Juscelino Kubitschek became president in 1956 and assumed a conciliatory posture towards the political opposition that allowed him to govern without major crises. The economy and industrial sector grew remarkably, but his greatest achievement was the construction of

3060-530: A prominent role in the League of Nations ; Internally, from the crisis of Encilhamento and the Navy Revolts , a prolonged cycle of financial, political and social instability began until the 1920s, keeping the country besieged by various rebellions, both civilian and military. Little by little, a cycle of general instability sparked by these crises undermined the regime to such an extent that in

3213-468: A research approach. Neither one is less effective than the other since they have their particular purpose in science. Typically empirical research produces observations that need to be explained; then theoretical research tries to explain them, and in so doing generates empirically testable hypotheses; these hypotheses are then tested empirically, giving more observations that may need further explanation; and so on. See Scientific method . A simple example of

3366-493: A single, all-encompassing definition that is embraced by all who engage in it. Research, in its simplest terms, is searching for knowledge and searching for truth. In a formal sense, it is a systematic study of a problem attacked by a deliberately chosen strategy, which starts with choosing an approach to preparing a blueprint (design) and acting upon it in terms of designing research hypotheses, choosing methods and techniques, selecting or developing data collection tools, processing

3519-455: A variety of approaches, such as queer theory or feminist theory. Artistic research , also seen as 'practice-based research', can take form when creative works are considered both the research and the object of research itself. It is the debatable body of thought which offers an alternative to purely scientific methods in research in its search for knowledge and truth. The controversial trend of artistic teaching becoming more academics-oriented

3672-418: Is " creative and systematic work undertaken to increase the stock of knowledge ". It involves the collection, organization, and analysis of evidence to increase understanding of a topic, characterized by a particular attentiveness to controlling sources of bias and error . These activities are characterized by accounting and controlling for biases. A research project may be an expansion of past work in

3825-521: Is a discipline within the study of applied ethics . Its scope ranges from general scientific integrity and misconduct to the treatment of human and animal subjects. The social responsibilities of scientists and researchers are not traditionally included and are less well defined. The discipline is most developed in medical research . Beyond the issues of falsification, fabrication, and plagiarism that arise in every scientific field, research design in human subject research and animal testing are

3978-521: Is a folk etymology for a word for the plant related to an Arabic or Asian word for a red plant. As brazilwood produces a deep red dye, it was highly valued by the European textile industry and was the earliest commercially exploited product from Brazil. Throughout the 16th century, massive amounts of brazilwood were harvested by indigenous peoples (mostly Tupi ) along the Brazilian coast, who sold

4131-490: Is also the subject of significant global interest, as environmental degradation (through processes such as deforestation ) has direct impacts on global issues such as climate change and biodiversity loss . The territory of present-day Brazil was inhabited by numerous tribal nations prior to the landing of explorer Pedro Álvares Cabral in 1500. Subsequently claimed by the Portuguese Empire , Brazil remained

4284-462: Is an approach that involves the development of theory as opposed to using observation and experimentation. As such, non-empirical research seeks solutions to problems using existing knowledge as its source. This, however, does not mean that new ideas and innovations cannot be found within the pool of existing and established knowledge. Non-empirical research is not an absolute alternative to empirical research because they may be used together to strengthen

4437-590: Is becoming more common. This method has benefits that using one method alone cannot offer. For example, a researcher may choose to conduct a qualitative study and follow it up with a quantitative study to gain additional insights. Big data has brought big impacts on research methods so that now many researchers do not put much effort into data collection; furthermore, methods to analyze easily available huge amounts of data have also been developed. Types of Research Method 1. Observatory Research Method 2. Correlation Research Method Non-empirical ( theoretical ) research

4590-621: Is celebrated as a protection of privacy, while simultaneously when similar functions are used by cultural groups (i.e. indigenous communities) this is denounced as "access control" and reprehended as censorship. Brazil Brazil , officially the Federative Republic of Brazil , is the largest and easternmost country in South America and Latin America . It is the world's fifth-largest country by area and one of

4743-408: Is data collected specifically for the research, such as through interviews or questionnaires. Secondary data is data that already exists, such as census data, which can be re-used for the research. It is good ethical research practice to use secondary data wherever possible. Mixed-method research, i.e. research that includes qualitative and quantitative elements, using both primary and secondary data,

4896-415: Is known as empirical research . The results of the data analysis in rejecting or failing to reject the null hypothesis are then reported and evaluated. At the end, the researcher may discuss avenues for further research . However, some researchers advocate for the reverse approach: starting with articulating findings and discussion of them, moving "up" to identification of a research problem that emerges in

5049-583: Is known as meta-research . A researcher is a person who conducts research, especially in order to discover new information or to reach a new understanding. In order to be a social researcher or a social scientist , one should have enormous knowledge of subjects related to social science that they are specialized in. Similarly, in order to be a natural science researcher, the person should have knowledge of fields related to natural science ( physics , chemistry , biology , astronomy , zoology and so on). Professional associations provide one pathway to mature in

5202-454: Is leading to artistic research being accepted as the primary mode of enquiry in art as in the case of other disciplines. One of the characteristics of artistic research is that it must accept subjectivity as opposed to the classical scientific methods. As such, it is similar to the social sciences in using qualitative research and intersubjectivity as tools to apply measurement and critical analysis. Artistic research has been defined by

5355-487: Is no real dry season , but there are some variations in the period of the year when most rain falls. Temperatures average 25 °C (77 °F), with more significant temperature variation between night and day than between seasons. Over central Brazil, rainfall is more seasonal, characteristic of a savanna climate. This region is as extensive as the Amazon basin but has a very different climate as it lies farther south at

5508-460: Is not feasible, the researcher may collect data on participant and situational characteristics to statistically control for their influence on the dependent, or outcome, variable. If the intent is to generalize from the research participants to a larger population, the researcher will employ probability sampling to select participants. In either qualitative or quantitative research, the researcher(s) may collect primary or secondary data. Primary data

5661-1012: Is often biased in the languages that are preferred ( linguicism ) and the geographic locations where research occurs. Periphery scholars face the challenges of exclusion and linguicism in research and academic publication. As the great majority of mainstream academic journals are written in English, multilingual periphery scholars often must translate their work to be accepted to elite Western-dominated journals. Multilingual scholars' influences from their native communicative styles can be assumed to be incompetence instead of difference. For comparative politics, Western countries are over-represented in single-country studies, with heavy emphasis on Western Europe, Canada, Australia, and New Zealand. Since 2000, Latin American countries have become more popular in single-country studies. In contrast, countries in Oceania and

5814-515: Is only when a range of tests are consistent over many kinds of data, researchers, and methods can one have confidence in the results." Plato in Meno talks about an inherent difficulty, if not a paradox, of doing research that can be paraphrased in the following way, "If you know what you're searching for, why do you search for it?! [i.e., you have already found it] If you don't know what you're searching for, what are you searching for?!" The goal of

5967-736: Is very powerful strategy for demonstrating methodology to health professions education as well as best suited for exploring challenging problems in health professions educations. In addition, PMP researcher Mandy Sha argued that a project management approach is necessary to control the scope, schedule, and cost related to qualitative research design, participant recruitment, data collection, reporting, as well as stakeholder engagement . The quantitative data collection methods rely on random sampling and structured data collection instruments that fit diverse experiences into predetermined response categories. These methods produce results that can be summarized, compared, and generalized to larger populations if

6120-650: Is well documented in three large intracratonic basins in Brazil (Solimoes, Amazonas and Paranaiba basins) and in Bolivia. By the Early Carboniferous (c. 350 Ma ) glacial strata were beginning to accumulate in sub-Andean basins of Bolivia , Argentina and Paraguay . By the mid-Carboniferous glaciation had spread to Antarctica, Australia, southern Africa, the Indian Subcontinent , Asia and

6273-459: The most populated countries . Its capital is Brasília , and its most populous city is São Paulo . Brazil is a federation composed of 26 states and a Federal District . It is the only country in the Americas where Portuguese is an official language . Brazil is among the world's most multicultural and ethnically diverse nations, due to over a century of mass immigration from around

6426-530: The Arab League . The word Brazil probably comes from the Portuguese word for brazilwood , a tree that once grew plentifully along the Brazilian coast. In Portuguese, brazilwood is called pau-brasil , with the word brasil commonly given the etymology "red like an ember ", formed from brasa ('ember') and the suffix -il (from -iculum or -ilium ). It has alternatively been suggested that this

6579-918: The Arabian Peninsula . During the Late Carboniferous glacial accumulation (c. 300 Ma) a very large area of Gondwana land mass was experiencing glacial conditions. The thickest glacial deposits of Permo-Carboniferous age are the Dwyka Formation (1000 m thick) in the Karoo Basin in southern Africa, the Itararé Group of the Paraná Basin , Brazil (1400 m) and the Carnarvon Basin in eastern Australia. The Permo-Carboniferous glaciations are significant because of

6732-540: The Caribbean are the focus of very few studies. Patterns of geographic bias also show a relationship with linguicism: countries whose official languages are French or Arabic are far less likely to be the focus of single-country studies than countries with different official languages. Within Africa, English-speaking countries are more represented than other countries. Generalization is the process of more broadly applying

6885-911: The European League of Institutes of the Arts launched The Florence Principles' on the Doctorate in the Arts . The Florence Principles relating to the Salzburg Principles and the Salzburg Recommendations of the European University Association name seven points of attention to specify the Doctorate / PhD in the Arts compared to a scientific doctorate / PhD. The Florence Principles have been endorsed and are supported also by AEC , CILECT , CUMULUS and SAR . The historical method comprises

7038-676: The Governorate General of Brazil in the city of Salvador , which became the capital of a single and centralized Portuguese colony in South America. In the first two centuries of colonization, Indigenous and European groups lived in constant war, establishing opportunistic alliances in order to gain advantages against each other. By the mid-16th century, cane sugar had become Brazil's most important export, while slaves purchased in Sub-Saharan Africa in

7191-461: The Kasimovian , which is today associated with glacial periods . This reduction in the greenhouse effect was coupled with burial of organic carbon as charcoal or coal, with lignin and cellulose (as tree trunks and other vegetation debris) accumulating and being buried in the great Carboniferous coal measures . The reduction of carbon dioxide levels in the atmosphere would be enough to begin

7344-884: The Mantiqueira and Espinhaço mountains and the Serra do Mar . In the north, the Guiana Highlands form a major drainage divide, separating rivers that flow south into the Amazon Basin from rivers that empty into the Orinoco River system, in Venezuela, to the north. The highest point in Brazil is the Pico da Neblina at 2,994 meters (9,823 ft), and the lowest is the Atlantic Ocean. Brazil has

7497-542: The Petrobras corruption scandal . President Temer himself was also accused of corruption . According to a 2018 poll, 62% of the population said that corruption was Brazil's biggest problem. In the fiercely disputed 2018 elections , the controversial conservative candidate Jair Bolsonaro of the Social Liberal Party (PSL) was elected president, winning in the second round against Fernando Haddad , of

7650-632: The Quilombo of Palmares , and to repress all movements for autonomy or independence , such as the Minas Gerais Conspiracy . In late 1807, Spanish and Napoleonic forces threatened the security of continental Portugal , causing Prince Regent John , in the name of Queen Maria I , to move the royal court from Lisbon to Rio de Janeiro . There they established some of Brazil's first financial institutions, such as its local stock exchanges and its National Bank , additionally ending

7956-491: The South American country. Home to 60% of the Amazon rainforest , which accounts for approximately one-tenth of all species in the world, Brazil is considered to have the greatest biodiversity of any country on the planet, containing over 70% of all animal and plant species catalogued. Brazil has the most known species of plants (55,000), freshwater fish (3,000) and mammals (over 689). It also ranks third on

8109-497: The South Pole changed. At the beginning of the LPIA, ice centres were concentrated in western South America; they later shifted eastward across Africa and by the end of the ice age were concentrated in Australia. Evidence from sedimentary basins suggests individual ice centres lasted for approximately 10 million years, with their peaks alternating with periods of low or absent permanent ice coverage. The first glacial episodes of

8262-467: The Tupi–Guarani family and fought among themselves. Though the first settlement was founded in 1532, colonization effectively began in 1534, when King John III of Portugal divided the territory into the fifteen private and autonomous captaincies . However, the decentralized and unorganized tendencies of the captaincies proved problematic, and in 1549 the Portuguese king restructured them into

8415-596: The Workers Party (PT), with the support of 55.13% of the valid votes. In the early 2020s, Brazil became one of the hardest hit countries during the COVID-19 pandemic , receiving the second-highest death toll worldwide after the United States. In May 2021, Luiz Inácio Lula da Silva stated that he would run for a third term in the 2022 Brazilian general election against Bolsonaro. In October 2022, Lula

8568-497: The first constitution in 1824 led to the formation of a bicameral legislature, now called the National Congress . Slavery was abolished in 1888. The country became a presidential republic in 1889 following a military coup d'état . An authoritarian military dictatorship emerged in 1964 and ruled until 1985, after which civilian governance resumed. Brazil's current constitution , formulated in 1988, defines it as

8721-457: The greenhouse effect , with CO 2 levels rising to 300 ppm in the following Permian period. Once these factors brought a halt and a small reversal in the spread of ice sheets, the lower planetary albedo resulting from the fall in size of the glaciated areas would have been enough for warmer summers and winters and thus limit the depth of snowfields in areas from which the glaciers expanded. Rising sea levels produced by global warming drowned

8874-451: The researcher . The degree of originality of the research is among the major criteria for articles to be published in academic journals and usually established by means of peer review . Graduate students are commonly required to perform original research as part of a dissertation . Scientific research is a systematic way of gathering data and harnessing curiosity . This research provides scientific information and theories for

9027-642: The scientific lacuna in culturally sensitive methods of data collection. Western methods of data collection may not be the most accurate or relevant for research on non-Western societies. For example, " Hua Oranga " was created as a criterion for psychological evaluation in Māori populations, and is based on dimensions of mental health important to the Māori people – "taha wairua (the spiritual dimension), taha hinengaro (the mental dimension), taha tinana (the physical dimension), and taha whanau (the family dimension)". Research

9180-475: The slave market of Western Africa (not only those from Portuguese allies of their colonies in Angola and Mozambique ), had become its largest import, to cope with sugarcane plantations , due to increasing international demand for Brazilian sugar. Brazil received more than 2.8 million slaves from Africa between the years 1500 and 1800. By the end of the 17th century, sugarcane exports began to decline and

9333-453: The " economic miracle ", the regime reached a peak in popularity in the early 1970s. Slowly, however, the wear and tear of years of dictatorial power had not slowed the repression, even after the defeat of the leftist guerrillas. The inability to deal with the economic crises of the period and popular pressure made an opening policy inevitable, which from the regime side was led by Generals Ernesto Geisel and Golbery do Couto e Silva . With

9486-634: The 1930s, three attempts to remove Vargas and his supporters from power failed. The first was the Constitutionalist Revolution in 1932, led by São Paulo's oligarchy . The second was a Communist uprising in November 1935, and the last one a putsch attempt by local fascists in May 1938. The 1935 uprising created a security crisis in which Congress transferred more power to the executive branch. The 1937 coup d'état resulted in

9639-481: The 1978 Belmont Report . Today, research ethics committees , such as those of the US , UK , and EU , govern and oversee the responsible conduct of research. Meta-research is the study of research through the use of research methods. Also known as "research on research", it aims to reduce waste and increase the quality of research in all fields. Meta-research concerns itself with the detection of bias, methodological flaws, and other errors and inefficiencies. Among

9792-434: The Americas, with a total area of 8,515,767.049 km (3,287,956 sq mi), including 55,455 km (21,411 sq mi) of water. North to South, Brazil is also the longest country in the world, spanning 4,395 km (2,731 mi) from north to south, and the only country in the world that has the equator and the Tropic of Capricorn running through it. It spans four time zones ; from UTC−5 comprising

Nonetheless, ice caps of a much lower volume and area remained in Australia. Another long regional interval also limited to Australia from the middle Kungurian to the early Capitanian , known as P3, though unlike the previous glaciations, this one and the following P4 glaciation

10098-508: The Atkan Formation of Magadan Oblast , Russia have been interpreted as being glacigenic, although recent analyses have challenged this interpretation, suggesting that these diamictites formed during a Capitanian integrlacial interval as a result of volcanogenic debris flows associated with the formation of the Okhotsk–Taigonos Volcanic Arc. The tropics experienced a cyclicity between wetter and drier periods that may have been related to changes between cold glacials and warm interglacials. In

10251-443: The Brazilian economy. Cardoso won the 1994 election , and again in 1998 . The peaceful transition of power from Cardoso to his main opposition leader, Luiz Inácio Lula da Silva ( elected in 2002 and re-elected in 2006 ), was seen as proof that Brazil had achieved a long-sought political stability. However, sparked by indignation and frustrations accumulated over decades from corruption, police brutality , inefficiencies of

10404-666: The LPIA melted in what is now eastern Australia around 255 Mya, during the late Wuchiapingian. The time intervals here referred to as glacial and interglacial periods represented intervals of several million years corresponding to colder and warmer icehouse intervals, respectively, were influenced by long term variations in palaeogeography, greenhouse gas levels, and geological processes such as rates of volcanism and of silicate weathering and should not be confused with shorter term cycles of glacials and interglacials that are driven by astronomical forcing caused by Milankovitch cycles. According to Eyles and Young, "Renewed Late Devonian glaciation

10557-409: The LPIA occurred during the late Famennian and the Tournaisian , with δN evidence showing that the transition from greenhouse to icehouse was a stepwise process and not an immediate change. These Early Mississippian glaciations were transient and minor, with them sometimes being considered discrete glaciations separate from and preceding the LPIA proper. Between 335 and 330 Mya, or sometime between

10710-662: The LPIA. The tectonic assembly of the continents of Euramerica and Gondwana into Pangaea , in the Hercynian - Alleghany Orogeny , made a major continental land mass within the Antarctic region and an increase in carbon sequestration via silicate weathering , which led to progressive cooling of summers, and the snowfields accumulating in winters, which caused mountainous alpine glaciers to grow, and then spread out of highland areas. That made continental glaciers , which spread to cover much of Gondwana. Modelling evidence points to tectonically induced carbon dioxide removal via silicate weathering to have been sufficient to generate

10863-432: The LPIA. The Lhasa terrane became glaciated during this stage of the Carboniferous. A relatively warm interglacial interval spanning the Kasimovian and Gzhelian, coinciding with the Alykaevo Climatic Optimum, occurred between this first major glacial period and the later second major glacial period. The Paraná Basin nonetheless experienced its final glaciation during the early Gzhelian. The second glacial period occurred from

11016-695: The Midland Basin of Texas , increased aeolian sedimentation reflective of heightened aridity occurred during warmer intervals, as it did in the Paradox Basin of Utah . The evolution of plants following the Silurian-Devonian Terrestrial Revolution and the subsequent adaptive radiation of vascular plants on land began a long-term increase in planetary oxygen levels. Large tree ferns , growing to 20 m (66 ft) high, were secondarily dominant to

11169-798: The Portuguese had to fight, notably the French in Rio during the 1560s , in Maranhão during the 1610s , and the Dutch in Bahia and Pernambuco , during the Dutch–Portuguese War , after the end of Iberian Union . The Portuguese colonial administration in Brazil had two objectives that would ensure colonial order and the monopoly of Portugal's wealthiest and largest colony: to keep under control and eradicate all forms of slave rebellion and resistance, such as

11322-541: The Portuguese monopoly on Brazilian trade and opening Brazil's ports to other nations. In 1809, in retaliation for being forced into exile, the Prince Regent ordered the conquest of French Guiana . With the end of the Peninsular War in 1814, the courts of Europe demanded that Queen Maria I and Prince Regent John return to Portugal, deeming it unfit for the head of an ancient European monarchy to reside in

11475-700: The Rheic Ocean, has been hypothesised to have been the cause of the Carboniferous-Earliest Permian Biodiversification Event . Milankovitch cycles profound impacts on marine life at the height of the LPIA, with high-latitude species being more strongly affected by glacial-interglacial cycles than low-latitude species. At the beginning of the LPIA, the transition from a greenhouse to an icehouse climate, in conjunction with increases in atmospheric oxygen concentrations, reduced thermal stratification and increased

11628-554: The Western Hemisphere was excavated in the Amazon basin of Brazil and radiocarbon dated to 8,000 years ago (6000 BC). The pottery was found near Santarém and provides evidence that the region supported a complex prehistoric culture. The Marajoara culture flourished on Marajó in the Amazon delta from AD 400 to 1400, developing sophisticated pottery, social stratification , large populations, mound building , and complex social formations such as chiefdoms . Around

11781-458: The accuracy of observation of the time, the prediction will be verified. As the accuracy of observation improves with time, the hypothesis may no longer provide an accurate prediction. In this case, a new hypothesis will arise to challenge the old, and to the extent that the new hypothesis makes more accurate predictions than the old, the new will supplant it. Researchers can also use a null hypothesis, which states no relationship or difference between

11934-484: The almost-unknown Fernando Collor , who was subsequently impeached by the National Congress in 1992. Collor was succeeded by his vice-president, Itamar Franco , who appointed Fernando Henrique Cardoso Minister of Finance. In 1994, Cardoso produced a highly successful Plano Real , that, after decades of failed economic plans made by previous governments attempting to curb hyperinflation, finally stabilized

12087-712: The approval of the Golden Law . The foreign-affairs policies of the monarchy dealt with issues with the countries of the Southern Cone with whom Brazil had borders. Long after the Cisplatine War that resulted in the independence of Uruguay , Brazil won three international wars during the 58-year reign of Pedro II: the Platine War , the Uruguayan War and the devastating Paraguayan War ,

12240-470: The areas that raise ethical questions most often. The list of historic cases includes many large-scale violations and crimes against humanity such as Nazi human experimentation and the Tuskegee syphilis experiment which led to international codes of research ethics. No approach has been universally accepted, but typically-cited codes are the 1947 Nuremberg Code , the 1964 Declaration of Helsinki , and

12393-506: The arrival of the Europeans, the boundaries between these groups and their subgroups were marked by wars that arose from differences in culture, language and moral beliefs. These wars also involved large-scale military actions on land and water, with cannibalistic rituals on prisoners of war . While heredity had some weight, leadership was a status more won over time than assigned in succession ceremonies and conventions. Slavery among

12546-756: The arts. A simpler understanding by Julian Klein defines artistic research as any kind of research employing the artistic mode of perception. For a survey of the central problematics of today's artistic research, see Giaco Schiesser . According to artist Hakan Topal , in artistic research, "perhaps more so than other disciplines, intuition is utilized as a method to identify a wide range of new and unexpected productive modalities". Most writers, whether of fiction or non-fiction books, also have to do research to support their creative work. This may be factual, historical, or background research. Background research could include, for example, geographical or procedural research. The Society for Artistic Research (SAR) publishes

12699-528: The cancellation of the 1938 election and formalized Vargas as dictator, beginning the Estado Novo era. During this period, government brutality and censorship of the press increased. During World War II , Brazil remained neutral until August 1942, when the country suffered retaliation by Nazi Germany and Fascist Italy in a strategic dispute over the South Atlantic, and, therefore, entered

12852-513: The central power, coupled with old and latent social tensions peculiar to a vast, slaveholding and newly independent nation state . This period of internal political and social upheaval, which included the Praieira revolt in Pernambuco , was overcome only at the end of the 1840s, years after the end of the regency, which occurred with the premature coronation of Pedro II in 1841. During

13005-418: The continent's interior, sharing land borders with Uruguay to the south; Argentina and Paraguay to the southwest; Bolivia and Peru to the west; Colombia to the northwest; and Venezuela , Guyana , Suriname and France (French overseas region of French Guiana ) to the north. It shares a border with every South American country except Ecuador and Chile . The brazilian territory also encompasses

13158-422: The data are collected using proper sampling and data collection strategies. Quantitative research is concerned with testing hypotheses derived from theory or being able to estimate the size of a phenomenon of interest. If the research question is about people, participants may be randomly assigned to different treatments (this is the only way that a quantitative study can be considered a true experiment). If this

13311-623: The data, interpretation, and ending with presenting solution(s) of the problem. Another definition of research is given by John W. Creswell , who states that "research is a process of steps used to collect and analyze information to increase our understanding of a topic or issue". It consists of three steps: pose a question, collect data to answer the question, and present an answer to the question. The Merriam-Webster Online Dictionary defines research more generally to also include studying already existing knowledge: "studious inquiry or examination; especially : investigation or experimentation aimed at

13464-605: The demands of revolutionaries who had taken the city of Porto , John VI departed for Lisbon. There he swore an oath to the new constitution, leaving his son, Prince Pedro de Alcântara , as Regent of the Kingdom of Brazil . Tensions between Portuguese and Brazilians increased and the Portuguese Cortes , guided by the new political regime imposed by the Liberal Revolution , tried to re-establish Brazil as

13617-424: The discovery and interpretation of facts, revision of accepted theories or laws in the light of new facts, or practical application of such new or revised theories or laws". Original research , also called primary research , is research that is not exclusively based on a summary, review, or synthesis of earlier publications on the subject of research. This material is of a primary-source character. The purpose of

13770-601: The discovery of gold by bandeirantes in the 1690s would become the new backbone of the colony's economy, fostering a gold rush which attracted thousands of new settlers to Brazil from Portugal and all Portuguese colonies around the world. This increased level of immigration in turn caused some conflicts between newcomers and old settlers. Portuguese expeditions known as bandeiras gradually expanded Brazil's original colonial frontiers in South America to its approximately current borders. In this era other European powers tried to colonize parts of Brazil, in incursions that

13923-399: The dragonfly-like Meganeura , an aerial predator, with a wingspan of 60 to 75 cm. The herbivorous stocky-bodied and armoured millipede-like Arthropleura was 1.8 metres (5.9 ft) long, and the semiterrestrial Hibbertopterid eurypterids were perhaps as large, and some scorpions reached 50 or 70 centimetres (20 or 28 in). Earth's increased planetary albedo produced by

14076-518: The earliest glaciations of the LPIA began. The uplift, driven by mantle dynamics rather than by crustal tectonic processes, is evidenced by the increase in temperature of the southwestern Gondwanan crust as shown by changing compositions of granites formed at this time. The LPIA, like the present Quaternary glaciation , saw glacial-interglacial cycles governed by Milankovitch cycles acting on timescales of tens of thousands to millions of years. Periods of low obliquity, which decreased annual insolation at

14229-477: The enactment of the Amnesty Law in 1979, Brazil began a slow return to democracy , which was completed during the 1980s. Civilians returned to power in 1985 when José Sarney assumed the presidency. He became unpopular during his tenure through failure to control the economic crisis and hyperinflation he inherited from the military regime. Sarney's unsuccessful government led to the election in 1989 of

14382-419: The expanding ice sheets would lead to positive feedback loops, spreading the ice sheets still further, until the process hit a limit. Falling global temperatures would eventually limit plant growth, and the rising levels of oxygen would increase the frequency of fire-storms because damp plant matter could burn. Both these effects return carbon dioxide to the atmosphere, reversing the "snowball" effect and forcing

14535-425: The explanation of the nature and the properties of the world. It makes practical applications possible. Scientific research may be funded by public authorities, charitable organizations, and private organizations. Scientific research can be subdivided by discipline . Generally, research is understood to follow a certain structural process . Though the order may vary depending on the subject matter and researcher,

14688-730: The field. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research ) are documentation , discovery , interpretation , and the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemologies , which vary considerably both within and between humanities and sciences. There are several forms of research: scientific , humanities , artistic , economic, social , business, marketing , practitioner research , life, technological , etc. The scientific study of research practices

14841-460: The finding of meta-research is a low rates of reproducibility across a large number of fields. This widespread difficulty in reproducing research has been termed the " replication crisis ." In many disciplines, Western methods of conducting research are predominant. Researchers are overwhelmingly taught Western methods of data collection and study. The increasing participation of indigenous peoples as researchers has brought increased attention to

14994-400: The findings and literature review. The reverse approach is justified by the transactional nature of the research endeavor where research inquiry, research questions, research method, relevant research literature, and so on are not fully known until the findings have fully emerged and been interpreted. Rudolph Rummel says, "... no researcher should accept any one or two tests as definitive. It

15147-456: The first time, "a drought has covered all the way from the North to the country’s Southeast". It is the strongest drought in Brazil since the beginning of measurement in the 1950s, covering almost 60% of the country's territory. The drought is linked to deforestation and climate change. Brazilian topography is also diverse and includes hills, mountains, plains, highlands, and scrublands. Much of

15300-461: The following concepts are part of most formal historical research: Research is often conducted using the hourglass model structure of research. The hourglass model starts with a broad spectrum for research, focusing in on the required information through the method of the project (like the neck of the hourglass), then expands the research in the form of discussion and results. The major steps in conducting research are: The steps generally represent

15453-414: The following steps are usually part of most formal research, both basic and applied: A common misconception is that a hypothesis will be proven (see, rather, null hypothesis ). Generally, a hypothesis is used to make predictions that can be tested by observing the outcome of an experiment. If the outcome is inconsistent with the hypothesis, then the hypothesis is rejected (see falsifiability ). However, if

15606-459: The highest areas. The semiarid climatic region generally receives less than 800 millimeters (31.5 in) of rain, most of which generally falls in a period of three to five months of the year and occasionally less than this, creating long periods of drought. Brazil's 1877–78 Grande Seca (Great Drought), the worst in Brazil's history, caused approximately half a million deaths. A similarly devastating drought occurred in 1915. In 2024, for

15759-469: The humanities is historical research, which is embodied in historical method . Historians use primary sources and other evidence to systematically investigate a topic, and then to write histories in the form of accounts of the past. Other studies aim to merely examine the occurrence of behaviours in societies and communities, without particularly looking for reasons or motivations to explain these. These studies may be qualitative or quantitative, and can use

15912-659: The ice age. The closure of the Rheic Ocean and Iapetus Ocean saw disruption of warm-water currents in the Panthalassa Ocean and Paleotethys Sea, which may have also been a factor in the development of the LPIA. The capture of CO 2 through weathering of large igneous provinces emplaced during the Kungurian brought about the P3 glaciation. The Mississippian witnessed major uplift in southwestern Gondwana, where

16065-426: The independent or dependent variables. Research in the humanities involves different methods such as for example hermeneutics and semiotics . Humanities scholars usually do not search for the ultimate correct answer to a question, but instead, explore the issues and details that surround it. Context is always important, and context can be social, historical, political, cultural, or ethnic. An example of research in

16218-526: The indigenous groups had a different meaning than it had for Europeans, since it originated from a diverse socioeconomic organization, in which asymmetries were translated into kinship relations. Following the 1494 Treaty of Tordesillas , the land now called Brazil was claimed for the Portuguese Empire on 22 April 1500, with the arrival of the Portuguese fleet commanded by Pedro Álvares Cabral . The Portuguese encountered indigenous peoples divided into several ethnic societies, most of whom spoke languages of

16371-530: The large arborescent lycopods (30–40 m high) of the Carboniferous coal forests that flourished in equatorial swamps stretching from Appalachia to Poland , and later on the flanks of the Urals . The enhanced carbon sequestration raised the atmospheric oxygen levels to a peak of 35%, and lowered carbon dioxide level below the 300  parts per million (ppm), possibly as low as 180 ppm during

16524-478: The large areas of flatland where previously anoxic swamps assisted in burial and removal of carbon (as coal ). With a smaller area for deposition of carbon, more carbon dioxide was returned to the atmosphere, further warming the planet. Over the course of the Early and Middle Permian, glacial periods became progressively shorter while warm interglacials became longer, gradually transitioning the world from an icehouse to

16677-463: The largest war effort in Brazilian history. Although there was no desire among the majority of Brazilians to change the country's form of government , on 15 November 1889, in disagreement with the majority of the Imperial Army officers, as well as with rural and financial elites (for different reasons), the monarchy was overthrown by a military coup. A few days later, the national flag

16830-579: The last 150 years. Despite its growing economic and global profile, the country continues to face high levels of corruption , crime and social inequality . Brazil is a founding member of the United Nations , the G20 , BRICS , G4 , Mercosul , Organization of American States , Organization of Ibero-American States , and the Community of Portuguese Language Countries , and also an observer state of

16983-534: The last phase of the monarchy, internal political debate centered on the issue of slavery. The Atlantic slave trade was abandoned in 1850, as a result of the British Aberdeen Act and the Eusébio de Queirós Law , but only in May 1888, after a long process of internal mobilization and debate for an ethical and legal dismantling of slavery in the country , was the institution formally abolished with

17136-641: The late Gzhelian across the Carboniferous-Permian boundary to the early Sakmarian; ice sheets expanded from a core in Australia and India . This was the most intense interval of glaciation of the LPIA; in Australia, it is known as P1. An exceptionally intense cooling event occurred at 300 Ma. From the late Sakmarian onward, and especially following the Artinskian Warming Event (AWE), these ice sheets declined, as indicated by

17289-404: The late 2000s. Peer review is a form of self-regulation by qualified members of a profession within the relevant field. Peer review methods are employed to maintain standards of quality, improve performance, and provide credibility. In academia, scholarly peer review is often used to determine an academic paper's suitability for publication. Usually, the peer review process involves experts in

17442-655: The marked glacio- eustatic changes in sea level that resulted and which are recorded in non-glacial basins. Late Paleozoic glaciation of Gondwana could be explained by the migration of the supercontinent across the South Pole." In northern Ethiopia glacial landforms like striations , rôche moutonnées and chatter marks can be found buried beneath Late Carboniferous-Early Permian glacial deposits ( Edaga Arbi Glacials ). Glaciofluvial sandstones, moraines, boulder beds, glacially striated pavements, and other glacially derived geologic structures and beds are also known throughout

17595-602: The middle Viséan and earliest Serpukhovian , the LPIA proper began. A start in glacioeustatic sea level changes is recorded from Idaho at around this time. The first major glacial period occurred from the Serpukhovian to the Moscovian : ice sheets expanded from a core in southern Africa and South America. During the Bashkirian , a global eustatic sea level drop occurred, signifying the first major glacial maximum of

17748-465: The naturally regenerating forest, 44% was reported to be primary forest (consisting of native tree species with no clearly visible indications of human activity) and around 30% of the forest area was found within protected areas. For 2015, 56.% of the forest area was reported to be under public ownership and 44% private ownership . Many regions have starkly different microclimates . An equatorial climate characterizes much of northern Brazil. There

17901-487: The new capital city of Brasília , inaugurated in 1960. Kubitschek's successor, Jânio Quadros , resigned in 1961 less than a year after taking office. His vice-president, João Goulart , assumed the presidency, but aroused strong political opposition and was deposed in April 1964 by a coup that resulted in a military dictatorship . The new regime was intended to be transitory but gradually closed in on itself and became

18054-439: The north and semiarid deserts in the northeast, to temperate coniferous forests in the south and tropical savannas in central Brazil. In Brazil, forest cover is around 59% of the total land area, equivalent to 496,619,600 hectares (ha) of forest in 2020, down from 588,898,000 hectares (ha) in 1990. In 2020, naturally regenerating forest covered 485,396,000 hectares (ha) and planted forest covered 11,223,600 hectares (ha). Of

18207-470: The northern, northeastern regions and in the Cisplatina province. The last Portuguese soldiers surrendered on 8 March 1824; Portugal officially recognized Brazilian independence on 29 August 1825. On 7 April 1831, worn down by years of administrative turmoil and political dissent with both liberal and conservative sides of politics, including an attempt of republican secession and unreconciled to

18360-514: The official Portuguese name. Some early sailors called it the "Land of Parrots". In the Guaraní language , an official language of Paraguay , Brazil is called "Pindorama", meaning 'land of the palm trees'. Some of the earliest human remains found in the Americas , Luzia Woman , were found in the area of Pedro Leopoldo , Minas Gerais and provide evidence of human habitation going back at least 11,000 years. The earliest pottery ever found in

18513-764: The one in southern Victoria Land that flowed west-northwestward. The Sydney Basin of eastern Australia lay at a palaeolatitude of around 60°S to 70°S during the Early and Middle Permian, and its sedimentary successions preserve at least four phases of glaciation throughout this time. Debate exists as to whether the Northern Hemisphere experienced glaciation like the Southern Hemisphere did, with most palaeoclimate models suggesting that ice sheets did exist in Northern Pangaea but that they were very negligible in volume . Diamictites from

18666-480: The original research is to produce new knowledge rather than present the existing knowledge in a new form (e.g., summarized or classified). Original research can take various forms, depending on the discipline it pertains to. In experimental work, it typically involves direct or indirect observation of the researched subject(s), e.g., in the laboratory or in the field, documents the methodology , results, and conclusions of an experiment or set of experiments, or offers

18819-451: The outcome is consistent with the hypothesis, the experiment is said to support the hypothesis. This careful language is used because researchers recognize that alternative hypotheses may also be consistent with the observations. In this sense, a hypothesis can never be proven, but rather only supported by surviving rounds of scientific testing and, eventually, becoming widely thought of as true. A useful hypothesis allows prediction and within

18972-423: The overall process; however, they should be viewed as an ever-changing iterative process rather than a fixed set of steps. Most research begins with a general statement of the problem, or rather, the purpose for engaging in the study. The literature review identifies flaws or holes in previous research which provides justification for the study. Often, a literature review is conducted in a given subject area before

19125-439: The poles, were associated with high moisture flux from low latitudes and glacial expansion at high latitudes, while periods of high obliquity corresponded to warmer, interglacial periods. Data from Serpukhovian and Moscovian marine strata of South China point to glacioeustasy being driven primarily by long-period eccentricity, with a cyclicity of about 0.405 million years, and the modulation of the amplitude of Earth's obliquity, with

19278-529: The political establishment and public service , numerous peaceful protests erupted in Brazil in the middle of the first term of Dilma Rousseff , who had succeeded Lula after winning election in 2010 and again in 2014 by narrow margins. Rousseff was impeached by the Brazilian Congress in 2016, halfway into her second term, and replaced by her Vice-president Michel Temer , who assumed full presidential powers after Rousseff's impeachment

19431-417: The process of changing polar climates, leading to cooler summers which could not melt the previous winter's snow accumulations. The growth in snowfields to 6 m deep would create sufficient pressure to convert the lower levels to ice. Research indicates that changing carbon dioxide concentrations were the dominant driver of changes between colder and warmer intervals during the Early and Middle Permian portions of

19584-497: The repeated alterations of marine and nonmarine environments resulting from glacioeustatic rises and falls of sea levels linked to Milankovitch cycles. The development of high-frequency, high-amplitude glacioeustasy, which resulted in sea level changes of up to 120 metres between warmer and colder intervals, during the beginning of the LPIA, combined with the increased geographic separation of marine ecoregions and decrease in ocean circulation it caused in conjunction with closure of

19737-446: The research process is to produce new knowledge or deepen understanding of a topic or issue. This process takes three main forms (although, as previously discussed, the boundaries between them may be obscure): There are two major types of empirical research design: qualitative research and quantitative research. Researchers choose qualitative or quantitative methods according to the nature of the research topic they want to investigate and

19890-571: The research profession. The word research is derived from the Middle French " recherche ", which means "to go about seeking", the term itself being derived from the Old French term "recerchier," a compound word from "re-" + "cerchier", or "sercher", meaning 'search'. The earliest recorded use of the term was in 1577. Research has been defined in a number of different ways, and while there are similarities, there does not appear to be

20043-697: The research questions they aim to answer: Qualitative research refers to much more subjective non-quantitative, use different methods of collecting data, analyzing data, interpreting data for meanings, definitions, characteristics, symbols metaphors of things. Qualitative research further classified into the following types: Ethnography: This research mainly focus on culture of group of people which includes share attributes, language, practices, structure, value, norms and material things, evaluate human lifestyle. Ethno: people, Grapho: to write, this disciple may include ethnic groups, ethno genesis, composition, resettlement and social welfare characteristics. Phenomenology : It

20196-439: The same elite status as those of North America and Europe, because limitations on the availability of resources including high-quality paper and sophisticated image-rendering software and printing tools render these publications less able to satisfy standards currently carrying formal or informal authority in the publishing industry. These limitations in turn result in the under-representation of scholars from periphery nations among

20349-452: The same field who are consulted by editors to give a review of the scholarly works produced by a colleague of theirs from an unbiased and impartial point of view, and this is usually done free of charge. The tradition of peer reviews being done for free has however brought many pitfalls which are also indicative of why most peer reviewers decline many invitations to review. It was observed that publications from periphery countries rarely rise to

20502-413: The set of publications holding prestige status relative to the quantity and quality of those scholars' research efforts, and this under-representation in turn results in disproportionately reduced acceptance of the results of their efforts as contributions to the body of knowledge available worldwide. The open access movement assumes that all information generally deemed useful should be free and belongs to

20655-540: The southern part of the Arabian Peninsula. In southern Victoria Land, Antarctica, the Metschel Tillite, made up of reworked Devonian Beacon Supergroup sedimentary strata along with Cambrian and Ordovician granitoids and some Neoproterozoic metamorphic rocks, preserves glacial sediments indicating the presence of major ice sheets. Northern Victoria Land and Tasmania hosted a distinct ice sheet from

20808-697: The state of Acre and the westernmost portion of Amazonas , to UTC−4 in the western states, to UTC−3 in the eastern states (the national time ) and UTC−2 in the Atlantic islands . The climate of Brazil comprises a wide range of weather conditions across a large area and varied topography, but most of the country is tropical. According to the Köppen system , Brazil hosts six major climatic subtypes: desert , equatorial , tropical , semiarid , oceanic and subtropical . The different climatic conditions produce environments ranging from equatorial rainforests in

20961-421: The techniques and guidelines by which historians use historical sources and other evidence to research and then to write history. There are various history guidelines that are commonly used by historians in their work, under the headings of external criticism, internal criticism, and synthesis. This includes lower criticism and sensual criticism. Though items may vary depending on the subject matter and researcher,

21114-445: The terrain lies between 200 meters (660 ft) and 800 meters (2,600 ft) in elevation. The main upland area occupies most of the southern half of the country. The northwestern parts of the plateau consist of broad, rolling terrain broken by low, rounded hills. The southeastern section is more rugged, with a complex mass of ridges and mountain ranges reaching elevations of up to 1,200 meters (3,900 ft). These ranges include

21267-498: The timber to European traders (mostly Portuguese, but also French) in return for assorted European consumer goods. The official Portuguese name of the land, in original Portuguese records, was the "Land of the Holy Cross" ( Terra da Santa Cruz ), but European sailors and merchants commonly called it the "Land of Brazil" ( Terra do Brasil ) because of the brazilwood trade. The popular appellation eclipsed and eventually supplanted

21420-536: The time of the Portuguese arrival, the territory of current day Brazil had an estimated indigenous population of 7 million people, mostly semi-nomadic, who subsisted on hunting, fishing, gathering, and migrant agriculture. The population comprised several large indigenous ethnic groups (e.g., the Tupis , Guaranis , Gês , and Arawaks ). The Tupi people were subdivided into the Tupiniquins and Tupinambás . Before

21573-634: The triannual Journal for Artistic Research ( JAR ), an international, online, open access , and peer-reviewed journal for the identification, publication, and dissemination of artistic research and its methodologies, from all arts disciplines and it runs the Research Catalogue (RC), a searchable, documentary database of artistic research, to which anyone can contribute. Patricia Leavy addresses eight arts-based research (ABR) genres: narrative inquiry, fiction-based research, poetry, music, dance, theatre, film, and visual art. In 2016,

21726-418: The valid results of one study. Studies with a narrow scope can result in a lack of generalizability, meaning that the results may not be applicable to other populations or regions. In comparative politics, this can result from using a single-country study, rather than a study design that uses data from multiple countries. Despite the issue of generalizability, single-country studies have risen in prevalence since

21879-461: The vertical extent of the mixed layer , which promoted higher rates of microbial nitrification as revealed by an increase in δN bulk values. The rising levels of oxygen during the late Paleozoic icehouse had major effects upon evolution of plants and animals. Higher oxygen concentration (and accompanying higher atmospheric pressure) enabled energetic metabolic processes which encouraged evolution of large land-dwelling arthropods and flight, with

22032-534: The wake of the murder of his running mate, the defeated opposition presidential candidate Getúlio Vargas , supported by most of the military, successfully led the Revolution of 1930 . Vargas and the military were supposed to assume power temporarily, but instead closed down Congress, extinguished the Constitution, ruled with emergency powers and replaced the states' governors with his own supporters. In

22185-696: The war on the allied side . In addition to its participation in the battle of the Atlantic , Brazil also sent an expeditionary force to fight in the Italian campaign . With the Allied victory in 1945 and the end of the fascist regimes in Europe, Vargas's position became unsustainable, and he was swiftly overthrown in another military coup, with democracy "reinstated" by the same army that had ended it 15 years earlier. Vargas committed suicide in August 1954 amid

22338-478: The way that absolutists in Portugal had given in the succession of King John VI, Pedro I departed for Portugal to reclaim his daughter's crown after abdicating the Brazilian throne in favor of his five-year-old son and heir (Dom Pedro II ). As the new Emperor could not exert his constitutional powers until he came of age, a regency was set up by the National Assembly. In the absence of

22491-654: The world . Bounded by the Atlantic Ocean on the east, Brazil has a coastline of 7,491 kilometers (4,655 mi). Covering roughly half of South America's land area, it borders all other countries and territories on the continent except Ecuador and Chile . Brazil's Amazon basin includes a vast tropical forest home to diverse wildlife , a variety of ecological systems , and extensive natural resources spanning numerous protected habitats . This unique environmental heritage positions Brazil at number one of 17 megadiverse countries . The country's natural richness

22644-576: The world in both nominal and PPP terms—the largest in Latin America and the Southern Hemisphere . Classified as an upper-middle income economy by the World Bank , and a newly industrialized country by the IMF , Brazil has the largest share of wealth and the most complex economy in South America. It is also one of the world's major breadbaskets , being the largest producer of coffee for

22797-505: Was accepted on 31 August. Large street protests for and against her took place during the impeachment process. The charges against her were fueled by political and economic crises along with evidence of involvement with politicians from all the primary political parties. In 2017, the Supreme Court requested the investigation of 71 Brazilian lawmakers and nine ministers of President Michel Temer 's cabinet who were allegedly linked to

22950-430: Was in first place in the first round, with 48.43% of the support from the electorate, and received 50.90% of the votes in the second round. On 8 January 2023, a week after Lula's inauguration, a mob of Bolsonaro's supporters attacked Brazil's federal government buildings in the capital, Brasília , after several weeks of unrest. Brazil occupies a large area along the eastern coast of South America and includes much of

23103-493: Was largely limited to alpine glaciation. A final regional Australian interval lasted from the middle Capitanian to the late Wuchiapingian , known as P4. As with P3, P4's ice sheets were primarily high altitude glaciers. This glacial period was interrupted by a rapid warming interval corresponding to a surge in activity from the Emeishan Traps and corresponding Capitanian mass extinction event . The final alpine glaciers of

23256-590: Was particularly sensitive to the 1.2 million year long-period modulation cycle of obliquity. It also suggests that palaeolakes such as those found in the Junggar Basin likely played an important role as a carbon sink during the later stages of the LPIA, with their absorption and release of carbon dioxide acting as powerful feedback loops during Milankovitch cycle driven glacial and interglacial transitions.
