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.

An EFL lesson about the current events in Palestine. It is intended to be for intermediate students who wish to increase their listening skills through a short lesson in power point.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

functionally the same tissue and therefore are considered
as a complex

9.
10. Types of Dentin
• Primary dentin: is the dentin formed in a tooth before the completion of
the apical foramen of the root. Primary dentin is noted for its regular
pattern of tubules.
• Secondary dentin: is the dentin that is formed after the completion of the
apical foramen and continues to form throughout the life of the tooth.
• Peritubular (intratubular) dentin: dentin that creates the wall of the
dentinal tubule.
• Intertubular dentin: dentin found between the tubules.
• Mantle dentin: the first predentin that forms and matures within the tooth.
• Circumpulpal dentin: the layer of dentin around the outer pulpal wall.
33. Functions of the Dental PulpFunctions of the Dental Pulp
Nutrition: blood supply for pulp and dentin.
Sensory: changes in temp., vibration and chemical
that affect the dentin and pulp.
Formative: the pulp involve in the support,
maintenance and continued formation of dentin.
Defensive: triggering of inflammatory and immune
response.
Protective: Development and formation of
secondary and tertiary dentin which increase the
coverage of the pulp.
34. Anatomy of PulpAnatomy of Pulp
Pulp Chamber or coronal
pulp, located in the crown
of the tooth.
Root canal or radicular pulp,
is the portion of the pulp
located in the root area.
The apical foramen is the
opening from the pulp at the
apex of the tooth.
Accessory canals or lateral
canal, extra canal located on
the lateral portions of the
root.
Pulp horns or cornua
38. Zones-from outer to inner zone Description
Odontoblastic layer Lines the outer pulpal wall and
consists of the cell bodies of
odontoblast. Secondary dentin may
form in this area from the apposition of
odontoblast.
Cell-free zone Fewer cells than odontoblastic layer.
Nerve and capillary plexus located
here
Cell-rich zone Increased density of cells as compared
to cell-free zone and also a more
extensive vascular system
Pulpal-core Located in the center of the pulp
chamber, which has many cells and an
extensice vascular supply, similar to
cell-rich zone
Microscopic Zones in PulpMicroscopic Zones in Pulp
40. Contents of the PulpContents of the Pulp
Cells: Odontoblast, Fibroblast, white-blood cells,
Undifferentiated mesenchymal cells, Macrophages and
Lymphocytes. No fat cell.
Fibrous Matrix: Mostly reticular fibres and collagen fibres
(Type I and Type III).
Ground substance: Act as a medium to transport nutrients
to cells and metabolites of the cell to the blood vessels.
41. Vascularity and Nerves of the PulpVascularity and Nerves of the Pulp
The pulp organ is extensively vascular with vessels arising from the
external carotids to the superior or inferior alveolar arteries. It
drain by the same vein.
Blood flow is more rapid in the pulp than in most area of the body,
and the blood pressure is quite high.
The walls of the pulpal vessels become very thin as their enter the
pulp.
Nerves : Several large nerves enter the apical canal of each Molar
and Premolar and single ones enter the anterior teeth. This trunks
transverse the radicular pulp, proceed to the coronal area and
branch peripherally.
42. Blood and vessels enter and exit the dental pulp by way of the
apical and accessory foramina. Pulp is richly innervated; nerves
enter the pulp through the apical foramen, along with afferent
blood vessels and together form the neuro-vascular bundle.
45. Clinically Importance features of the Dental PulpClinically Importance features of the Dental Pulp
With age the pulp becomes less cellular. The number of cells
in the dental pulp decreases as cell death occurs with age.
The volume of the pulp chamber with continued deposition of
dentine. In older teeth, the pulp chamber decreases in size;
in some cases the pulp chamber can be obliterated. An
increase in calcification in the pulp occurs with age.
An increase in calcification in the pulp occurs with age.
52. Dentin Sensitivity:Dentin Sensitivity: three theoriesthree theories
Nerve in dentin – the dentin contains nerve endings that respond when it
is stimulated .
Odontoblastic process – the odontoblasts serve as receptors and are
coupled to nerves in the pulp.
Fluid movements in the dentinal tubules – the tubular nature of dentin
permits fluid movement to occur within the tubule when a stimulus is applied –
a movement registered by pulpal free nerve endings close to the dentin.
