Preta case

Preta case is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Preta case rather than just read about it. In short: On the night of March 9, 2005, a black dog named Preta, who was pregnant, was tied to the bumper of a car and dragged through the Brazilian city of Pelotas by 3 men: Fernando Siqueira Carvalho, Marcelo Ortiz Schuch, and Alberto Conceição da Cunha Neto. Repercussion The case gained repercussions throughout the country and also abroad.

Key takeaways

Preta case belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Preta case to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Preta case from memory before moving on to harder problems.

Reference excerpt

On the night of March 9, 2005, a black dog named Preta, who was pregnant, was tied to the bumper of a car and dragged through the Brazilian city of Pelotas by 3 men: Fernando Siqueira Carvalho, Marcelo Ortiz Schuch, and Alberto Conceição da Cunha Neto.

Repercussion The case gained repercussions throughout the country and also abroad. In Brazil, specifically, the case generated commotion in the population throughout the state of Rio Grande do Sul and gained national repercussions when it was reported on Fantástico, on national television, on March 17, 2005, later appearing then in several newspapers, magazines and TV programs, a fact that generated protests in several other centers in addition to the state. In view of the case, a public civil action was opened.

“Collectivities are subject to aggression against non-patrimonial values, bundled in them, in a diffuse way, including among them a feeling of respect for the lives of beings close to human beings. Case of the "Black Dog", savagely killed, with disintegration of her body and fetuses, dragged through the central streets of Pelotas, in plain sight, for the mere amusement of its authors, generating notorious social commotion. Aggression to feelings that are indispensable to collectivities, without which life in society becomes impossible.”

Conviction The conviction of the accused, which occurred years later, brought the case back to the media, and would have been based on the fact that the killing of the dog would have brought psychological damage to the local population. Alberto Conceição da Cunha Neto, for having a criminal record, received the highest sentence among the three accused, being sentenced in 2007 to one year of detention in a semi-open regime. Alberto Neto was ordered to pay compensation for collective moral damages in the amount of R$6,035.04, which must be directed to the city's municipal kennel. Alberto would have already responded to an investigation for mistreatment of animals and illegal possession of a weapon in 2003, when he shot and killed a boxer dog in neighboring Praia do Laranjal.

Worked examples

Example 1 — a first encounter with Preta case

Start with the simplest possible case. Write down what Preta case claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Preta case before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Preta case ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Preta case

In research: Preta case appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Preta case in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Preta case is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2005 animal deaths, 2005 crimes in Brazil, Animal killing, so understanding it makes those chapters shorter.
In everyday life: Look for Preta case outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
