A randomized controlled trial bakes causality into the data: random assignment severs every systematic link between treatment status and unobserved factors, so the simple difference in average outcomes is unbiased so long as compliance and sample integrity hold. The four quasi-experimental tools imitate that magic only by leaning on single-point assumptions. Ordinary least squares assumes no omitted variable is correlated with the

CONCORRENZA PERFETTA
tutte le imprese di un'industria offrono un bene assolutamente omogeneo
il consumatore conosce pienamente i prezzi e le caratteristiche dei beni offerti
tutte le imprese possono liberamente entrare e uscire dal mercato
vale la legge di Say, per la quale l’offerta crea la propria domanda
indifferenza del prezzo, l’impresa può decidere la quantità prodotta ma non il prezzo
la concorrenza perfetta è solo un mercato teorico, non può esistere nella...
Quote: “You lot may be letting yourselves out nicely, but I can’t. Nor can mother. We did her in alright.” — Eric (Guilt)
1.Blame and Internal Conflict: Eric’s blunt, almost accusatory tone with “We did her in alright” reveals his overwhelming sense of guilt. The inclusive pronoun “we” suggests he is accepting collective responsibility, contrasting with the others’ attempts to evade blame. This aligns with Sheila’s growing sense of responsibility as she, too, acknowledges her
...Quote: “I know I’m to blame — and I’m desperately sorry.” — Sheila (Responsibility)
1.Immediate Acceptance and Emotional Maturity: Sheila’s admission “I know I’m to blame” is direct and unfiltered, showing her immediate acceptance of responsibility. Unlike Eric, who only admits guilt under pressure, Sheila acknowledges her role unprompted, demonstrating a clear moral awakening. This contrasts sharply with Eric’s defensive, almost resentful confession.

...Quote: “A huge peak, black and huge” — The Prelude
1.Childlike Regression and Fear: The repetition of “huge” conveys Wordsworth’s stunned, almost childlike reaction to nature’s immense power. Similarly, in Tissue, Dharker uses fragile paper to show how easily human constructs can be overwhelmed by natural forces, such as “the sun” shining through borderlines, suggesting that both speakers are forced to confront their own insignificance.
2.Symbolism and Transience: The mountain
...Exposure vs. Storm on the Island
3. Exposure – “The merciless iced east winds that knive us…”
•Personification (Verb “Knive”): The verb “knive” anthropomorphizes the wind as a violent attacker, aligning nature with the enemy and suggesting that the soldiers are under constant assault. This mirrors the aggressive, militaristic imagery in Storm on the Island, where nature also becomes a relentless attacker through words like “bombarded.”
•Adjective (“Merciless”): The adjective
...Ozymandias vs. London
1. Ozymandias – “Look on my Works, ye Mighty, and despair!”
•Command Verb (Imperative): The verb “Look” conveys Ozymandias’s arrogance, attempting to assert dominance over future generations, suggesting an inflated sense of power. This contrasts with the powerless citizens in London, whose suffering is imposed upon them by external forces, not self-proclaimed power.
•Irony: The juxtaposition of “despair” with the ruined state of the statue highlights the
...Danos Causados por Animais – art. 502º CC:
Neste tipo de responsabilidade, o que gera essa mesmo, é a utilização de animais como fonte de perigo/risco e, este deve ser assumido por quem beneficia da utilização do animal.
De acordo com o exemplo, João, criados de cavalos, encarrega Carlos, seu capataz, de transportar para uma feira um cavalo para venda. Na feira, o cavalo solta-se, causa danos. No caso, a responsabilidade pelos danos causados pelo cavalo, será de quem vigia, mas também
