Java LinkedQueue Implementation (Generic)

This document presents the source code for a generic LinkedQueue class in Java. This implementation uses a singly linked list structure, adheres to the FIFO (First-In, First-Out) principle, and implements the Iterable interface.

package org.mp.repaso;

import java.util.Iterator; import java.util.NoSuchElementException;

public class LinkedQueue<T> implements Iterable<T> {

<span style="color:#ba2da2">private int</span> N; <span style="color:rgb(0,132,0)">// Tamaño de la cola</span>

basic identities

tan(x) = sin(x)/cos(x)

cot(x) = cos(x)/sin(x)

sec(x) = 1/cos(x)

The Great Depression: The Longest and Deepest Economic Downturn in American History

Causes of the Great Depression

In 1929, the prevailing economic theory held that the economy possessed self-correcting mechanisms that would prevent a severe depression. However, the Great Depression defied these expectations.

• Overproduction: Some economists believed the depression was caused by an excess of goods and services.
• Lack of Investment Opportunities: Others pointed to a decline in profitable investment opportunities.
• Technological Innovation: Joseph Schumpeter argued that the failure of entrepreneurs to introduce new products contributed to the depression.
• Stock Market Crash and Bank Panics: The stock market crash of 1929 and subsequent bank failures exacerbated

Extreme Sports and Personal Interests

1) I like cycling and camping, despite the fact that I don't do them usually. I would like to try canyoning, kayaking, jet skiing, and rock climbing because they are extreme sports that would probably make me feel really good, and I could relax with them.

The Benefits of Brain Training

2) Brain training can and must improve intellectual capacity. Just as physical exercise is good for the body, this mental training helps the mind to work better. The benefits can last; participating in interactive games helps maintain cognitive functions. Activities such as mind reading may delay or prevent memory loss. Those who took supervised brain training sessions showed lasting improvements in memory, reasoning, and processing... Continue reading "Extreme Sports, Brain Health, and Tech Innovations" »

Feminism

The origins of the second wave of Feminism can be traced back to the 1970s and the 1980s. A great number of women started writing and publishing books about the so-called notion of “Feminity”. Unlike the first wave of Feminism, which was a suffragist movement in which women were asking the right to vote, the second wave of Feminism goes beyond that. The feminist thinkers of the second wave based their theory on gender stereotyping. They claimed that equality between men and women had not been fully achieved because biological sex was the basis to determine the role a man or a woman must play in society.

Angela Carter's The Werewolf and Company of Wolves

The first reason why we can consider these texts as feminist is the issue of “authority

The Gold Standard: A Historical Overview

The gold standard is a monetary system in which money is freely convertible into a fixed amount of gold. It evolved from the variety of commodity money there was before the development of paper money and fractional reserves banking. It started to function in 1871. As we know, this century was characterized by globalization and an increase in international trade. Therefore, all trade imbalances between nations were settled with gold. The main priorities of the government were to maintain gold reserves and exchange rate stability.

The Trilemma of the Open Economy

If you had the Gold Standard you had fixed exchange rates and unrestricted capital mobility but Not Monetary Autonomy. As a result, countries always... Continue reading "The Gold Standard: History, Impact, and Challenges" »

MAKING OF EUROPE

1. Why Unite Europe?

• Post-War Devastation: World War II left Europe in ruins, with Germany divided, France in its Fourth Republic, and the Italian monarchy overthrown. Unification offered a path to recovery and stability.
• Economic Reconstruction: The creation of a common market aimed to boost trade and economic growth for war-torn nations.
• Preventing Future Conflicts: The trauma of war fostered a desire for lasting peace. Negotiation and cooperation became paramount, particularly between France and Germany.
• Franco-German Cooperation: The post-war period witnessed unprecedented cooperation between France and Germany, laying the foundation for European integration.
• Challenges of Integration: Integrating West Germany posed economic

Core Bioethical Principles

Moral Progress and Scientific Advancement

There is no possible scientific progress without moral progress too.

The Unity of the Human Person

Each human being is a biological, spiritual, and moral unity. What truly differentiates persons from other living beings is our capacity to behave morally.

Primacy of Human Life

The Belmont Report outlines general bioethical principles. A key principle is the primacy of present and real human life above any other interest or value. This also implies the respect for human dignity.

Understanding Human Dignity

The origin and foundation of the duty of absolute respect for human life are to be found in the dignity proper to the person, and not simply in the natural inclination to preserve... Continue reading "Bioethical Foundations: Human Life, Dignity, and Legal Status" »

Understanding Key Social Principles

The principle of subsidiarity derives from the Christian notion of society. It also determines the State's obligation to take additional, exceptional, complementary, and supportive action in social sectors or functions when society is unable to achieve its goals independently. It aims to promote and assist society. Main characteristics include:

1. It is a principle of reason, not of faith, limiting the natural rights of individuals and social groups.
2. It comprehends both dimensions of social life: the relationship between vertical and horizontal dimensions based on respect for and promotion of social freedom.
3. It is a grave, immutable principle, universal in time and space.
4. It self-adapts to each country and circumstance
