07. DEPTH STUDY GERMANY: NAZI REGIME - REICHSTAG FIRE SOURCESGeorge Dumitrache
07. DEPTH STUDY GERMANY: NAZI REGIME - REICHSTAG FIRE
On February 27, 1933, the German parliament (Reichstag) building burned down. The Nazi leadership and its coalition partners used the fire to claim that Communists were planning a violent uprising. They claimed that emergency legislation was needed to prevent this. The resulting act, commonly known as the Reichstag Fire Decree, abolished a number of constitutional protections and paved the way for Nazi dictatorship.
05. DEPTH STUDY GERMANY: NAZI REGIME - HITLER CONSOLIDATING POWER 1933-34.PPTXGeorge Dumitrache
05. DEPTH STUDY GERMANY: NAZI REGIME - HITLER CONSOLIDATING POWER 1933-34.PPTX
Following Hitler’s appointment as chancellor the Nazis were finally in a position of power.
However, this power was limited, as the Nazis were just one party in a three party coalition government, under President Hindenburg.
This topic will explore how the Nazis managed to eliminate their opposition and consolidate ultimate power over Germany, whilst maintaining an illusion of democracy.
It will first explore this topic in chronological order, from the Reichstag Fire through to the death of President Hindenburg, and then explore it thematically in the last section. On the 31 January 1933, Hitler, conscious of his lack of a majority in the Reichstag, immediately called for new elections to try and strengthen his position. The Nazis aimed to increase their share of the vote so that they would have a majority in the Reichstag. This would allow them to rule unopposed and unhindered by coalition governments.
Over the next two months, they launched themselves into an intense election campaign.
On 27 February 1933, as the campaign moved into its final, frantic days, the Reichstag, the German Parliament building, was set on fire and burnt down. An atmosphere of panic and terror followed the event.
This continued when a young Dutch communist, Van der Lubbe was arrested for the crime.
The Nazi Party used the atmosphere of panic to their advantage, encouraging anti-communism. Göring declared that the communists had planned a national uprising to overthrow the Weimar Republic. This hysteria helped to turn the public against the communists, one of the Nazis main opponents, and 4000 people were imprisoned.
The day after the fire, Hindenburg signed the Emergency Decree for the Protection of the German People. On the 28 February 1933, President Hindenburg signed the Emergency Decree for the Protection of the German People. This decree suspended the democratic aspects of the Weimar Republic and declared a state of emergency.
This decree gave the Nazis a legal basis for the persecution and oppression of any opponents, who were be framed as traitors to the republic. People could be imprisoned for any or no reason.
The decree also removed basic personal freedoms, such as the freedom of speech, the right to own property, and the right to trial before imprisonment.
Through these aspects the Nazis suppressed any opposition to their power, and were able to start the road from democracy to a dictatorship. The atmosphere of uncertainty following the Reichstag Fire secured many voters for the Nazi party.
The SA also ran a violent campaign of terror against any and all opponents of the Nazi regime. Many were terrified of voting of at all, and many turned to voting for the Nazi Party out of fear for their own safety. The elections were neither free or fair.
On the 5 March 1933, the elections took place, with an extremely high turnout of 89%.
The Nazis secured 43.9% of the vote.
DEPTH STUDY GERMANY: NAZI REGIME - 04. HITLER BECOMING CHANCELLOR 1933George Dumitrache
Hitler was not immediately appointed chancellor after the success of the July 1932 elections, despite being leader of the largest party in the Reichstag. It took the economic and political instability (with two more chancellors failing to stabilise the situation) to worsen, and the support of the conservative elite, to convince Hindenburg to appoint Hitler.
Hitler was sworn in as the chancellor of Germany on the 30 January 1933. The Nazis were now in power.
DEPTH STUDY GERMANY: WEIMAR REPUBLIC - 08. NAZIS IN THE WILDERNESSGeorge Dumitrache
The “Lean Years” (also called the "wilderness" years) of Hitler and the Nazi Party in Germany refer to the period between 1924 and 1928 when the Nazi party did not have high levels of support and still suffered from humiliation over the Munich Putsch. Why where these years “lean”?
DEPTH STUDY GERMANY: WEIMAR REPUBLIC - 07. STRESEMMAN ERA 1924-1929George Dumitrache
The period 1924-1929 was a time when the Weimar economy recovered and cultural life in Germany flourished. This dramatic turnabout happened in large part because of the role played by Gustav Stresemann who became Chancellor in August 1923 during the hyperinflation crisis.
DEPTH STUDY GERMANY: WEIMAR REPUBLIC - 06. THE BEER HALL PUTSCH 1923George Dumitrache
The Beer Hall Putsch, also known as the Munich Putsch, was a failed coup d'état by Nazi Party (Nationalsozialistische Deutsche Arbeiterpartei or NSDAP) leader Adolf Hitler, Generalquartiermeister Erich Ludendorff and other Kampfbund leaders in Munich, Bavaria, on 8–9 November 1923, during the Weimar Republic. Approximately two thousand Nazis marched on the Feldherrnhalle, in the city centre, but were confronted by a police cordon, which resulted in the deaths of 16 Nazi Party members and four police officers. Hitler escaped immediate arrest and was spirited off to safety in the countryside. After two days, he was arrested and charged with treason. The putsch brought Hitler to the attention of the German nation for the first time and generated front-page headlines in newspapers around the world. His arrest was followed by a 24-day trial, which was widely publicised and gave him a platform to express his nationalist sentiments to the nation. Hitler was found guilty of treason and sentenced to five years in Landsberg Prison, where he dictated Mein Kampf to fellow prisoners Emil Maurice and Rudolf Hess. On 20 December 1924, having served only nine months, Hitler was released. Once released, Hitler redirected his focus towards obtaining power through legal means rather than by revolution or force, and accordingly changed his tactics, further developing Nazi propaganda.
DEPTH STUDY GERMANY: WEIMAR REPUBLIC - 05. HYPERINFLATIONGeorge Dumitrache
Hyperinflation affected the German Papiermark, the currency of the Weimar Republic, between 1921 and 1923, primarily in 1923. It caused considerable internal political instability in the country, the occupation of the Ruhr by France and Belgium, and misery for the general populace.
DEPTH STUDY GERMANY: WEIMAR REPUBLIC - 03. THE TREATY OF VERSAILLES IMPACT ON...George Dumitrache
Thanks to the Treaty of Versailles, Germany's ability to produce revenue-generating coal and iron ore decreased. As war debts and reparations drained its coffers, the German government was unable to pay its debts. Some of the former World War I Allies didn't buy Germany's claim that it couldn't afford to pay.
DEPTH STUDY GERMANY: WEIMAR REPUBLIC - 02. THE NOVEMBER REVOLUTION 1918George Dumitrache
The German Revolution or November Revolution was a civil conflict in the German Empire at the end of the First World War that resulted in the replacement of the German federal constitutional monarchy with a democratic parliamentary republic that later became known as the Weimar Republic. The revolutionary period lasted from November 1918 until the adoption of the Weimar Constitution in August 1919. Among the factors leading to the revolution were the extreme burdens suffered by the German population during the four years of war, the economic and psychological impacts of the German Empire's defeat by the Allies, and growing social tensions between the general population and the aristocratic and bourgeois elite.

QUESTIONS AND ANSWERS - LEAGUE OF NATIONS. The League of Nations was an international organization, headquartered in Geneva, Switzerland, created after the First World War to provide a forum for resolving international disputes.
ABYSSINIAN CRISIS. The Abyssinian Crisis was over in 1936. Italy and Mussolini continually ignored the League of Nations and fully annexed Abyssinia on May 9th 1936. The League of Nations was shown to be ineffective. The League had not stood up against one of the strongest members and fulfilled the promise of collective security.
Manchurian Crisis. On September 18, 1931, an explosion destroyed a section of railway track near the city of Mukden. The Japanese, who owned the railway, blamed Chinese nationalists for the incident and used the opportunity to retaliate and invade Manchuria.
05. LEAGUE OF NATIONS - Great Depression and LON.pptxGeorge Dumitrache
GREAT DEPRESSION AND THE LEAGUE OF NATIONS. The Great Depression of 1930-33 meant people turned to extremist dictators such as Hitler and Mussolini, who were keen to invade other countries. This made it hard for the League to maintain peace. The League had some very ambitious plans and ideals – to stop war and make the world a better place.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2. KEYTERMSANDDEFINITIONS
Abrasion is a type of erosion in which rock fragments carried by waves grind
away a surface such as a cliff face.
Attrition is the process by which particles of rock being transported by the
sea are rounded and become smaller in size due to hitting one another.
Particles near the shoreline become smaller and more rounded due to more
frequent attrition.
Backwash is the movement of water back down the beach due
to the effect of gravity.
Constructive wave is a wave with a long wavelength and a low
height, which helps to build up beaches by deposition.
Denudation is the wearing away of the Earth’s surface. It includes
erosion, weathering and mass movements.
3. KEYTERMSANDDEFINITIONS
Deposition is the laying-down of material carried by rivers, the wind,
glaciers or the sea because of a loss of energy.
Destructive wave is a wave with a high height and a short wavelength,
which helps erode beach materials and cliffs.
Erosion is the wearing away of the Earth’s surface by a moving agent, such
as a river, glacier or the sea. In a river, there are several processes of
erosion, including hydraulic action, abrasion, attrition and solution. In
coastal areas, hydraulic action is the most potent form of erosion.
Fetch is the distance of open water over which wind can blow to create
waves. The greater the fetch the more potential power waves have when
they hit the coast. In the south and west of England the fetch stretches for
nearly 6000 km, to South America.
4.
5. KEYTERMSANDDEFINITIONS
Hydraulic action is the erosive force exerted by water. It is particularly
effective on jointed rocks, especially during storm conditions.
Longshore drift is the movement of material along a beach. When a wave
breaks obliquely (at an angle to the beach), pebbles are carried up the
beach in the direction of the wave (swash). The wave returns to the sea
(backwash) at right angles to the beach (direction of steepest slope),
carrying material with it. In this way, material moves along a beach.
Longshore drift may erode beaches and the formation of spits and bars.
Attempts to halt longshore drift include the erection of barriers known as
groynes.
6.
7. KEYTERMSANDDEFINITIONS
Prevailing wind is the direction from which the wind most commonly blows
in a region. In the British Isles, for example, the prevailing wind is South
Westerly, blowing from the Atlantic Ocean and bringing moist and mild
conditions.
Sea level is an average level of the sea, between high water mark and low
water mark.
Sediment cell is a length of coastline, which is essentially self contained as
far as the movement of sand and other sediment is concerned. The
boundaries of the sediment cells generally coincide with large estuaries or
prominent headlands.
Solution is the process by which the minerals in a rock, notably calcium
ions, are dissolved in acid water. It is also referred to as corrosion.
8. KEYTERMSANDDEFINITIONS
Spheroidal weathering is a form of chemical weathering in which
concentric or spherical shells of decayed rock are successively separated
from a block of rock, which commonly results in the formation of a rounded
boulder of decomposition.
Swash is the movement of material up the beach in the direction of the
prevailing wind.
Wave is a circular or elliptical movement of water near the surface of the
sea.
Wave refraction is the way in which a wave changes shape and loses speed
as it comes in contact with the seabed. If refraction is complete, waves
break parallel to the coastline. If refraction is not complete, longshore drift
occurs.
9. TOPICSUMMARY
Coasts are very varied landscapes and there are a number of factors
controlling coastal evolution.
● Waves result from friction between wind and the sea surface.
● There are three main types of breaker: spilling, plunging and surging.
● Constructive waves tend to occur when wave frequency is low,
particularly when these waves advance over a gently shelving sea floor.
● Destructive waves are the result of locally generated winds,
which create waves of high frequency.
10.
11.
12.
13. TOPICSUMMARY
Waves are dominant in some coastal environments, whereas in others it is
the tide or winds.
● Tides are regular movements in the sea’s surface, caused by the
gravitational pull of the Moon and Sun on the oceans.
● Coastal areas can be classified into microtidal, which have a very low
tidal range of less than 2 m; mesotidal, with a range of between 2 m and 4
m; and macrotidal, with a range of over 4 m.
● Storm surges are changes in the sea level caused by intense low-pressure
systems and high wind speeds.
14. TOPICSUMMARY
The change in speed and distortion of the wave fronts is called wave
refraction.
Waves perform a number of complex and interacting processes of erosion.
The main forms of erosion are hydraulic action, abrasion, attrition and
solution.
In addition, sub-aerial, or cliff-face processes include weathering and mass
movements.
Sediment transport is generally categorised into two modes: bed load and
suspended load.
The coastal sediment system, or littoral cell system, is a simplified model
in which each cell is self-contained, and where inputs and outputs are
balanced.
15.
16. ADDITIONALWORK
1. Outline the main characteristics of constructive and destructive waves.
2. Comment on the factors that lead to increased rates of marine erosion.
3. Briefly explain the processes of a) longshore drift and b) wave refraction.
4. What is a sediment cell? How is an understanding of sediment cells
useful in coastal studies?
5. With the use of annotated diagrams, distinguish between destructive
and constructive waves.
6. Explain how human activities can affect sediment cells.
