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

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

set the strategy of how demand will be met
• Tactical forecasts: forecasted needed for
how a firm operates processes on a day-to-
day basis
• The purpose of demand management is to
coordinate and control all sources of demand
• Two basic sources of demand
– Dependent demand: the demand for a product or
service caused by the demand for other products or
services
– Independent demand: the demand for a product
or service that cannot be derived directly from that
of other products
LO 2
23. 14-23
Demand Management Continued

Decomposition of a Time Series
• Time series: chronologically ordered
data that may contain one or more
components of demand
• Decomposition: identifying and
separating the time series data into
these components
• Seasonal variation
– Additive: the seasonal amount is constant
– Multiplicative: the seasonal variation is a
percentage of demand
LO 6
38. 14-38
Decomposition Using Least
Squares Regression
1. Determine the seasonal factor
2. Deseasonalize the original data
3. Develop a least squares regression
line for the deseasonalized data
4. Project the regression line through the
period of the forecast
5. Create the final forecast by adjusting
the regression line by the seasonal
factor
LO 6
41. 14-41
Simple Moving Average
• Useful when demand is neither growing
nor declining rapidly and does not have
seasonal characteristics
• Moving averages can be centered or
used to predict the following period
• Important to select the best period
– Longer gives more smoothing
– Shorter reacts quicker to trends

Weighted Moving Average
• The moving average formula implies an
equal weight being placed on each
value that is being averaged
• The weighted moving average permits
an unequal weighting on prior time
periods
– All the weights must sum to one
F = w A + w A + w A +...+w A
t 1 t-1 2 t-2 3 t-3 n t-n
LO 5
45. 14-45
Choosing Weights
• Experience and trial-and-error are the
simplest ways
• Generally, the most recent past is the
best indicator
• When data are seasonal, weights
should be established accordingly
LO 5
46. 14-46
Exponential Smoothing
• Most used of all forecasting techniques
• Integral part of all computerized forecasting
programs
• Widely used in retail and service
• Widely accepted because…
1. Exponential models are surprisingly accurate
2. Formulating an exponential model is relatively
easy
3. The user can understand how the model works
4. Little computation is required to use the model
5. Computer storage requirements are small
6. Tests for accuracy are easy to compute

Trend Effects in Exponential
Smoothing
• An trend in data causes the exponential
forecast to always lag the actual data
• Can be corrected somewhat by adding
in a trend adjustment
• To correct the trend, we need two
smoothing constants

Forecast Error
• Bias errors: when a consistent mistake
is made
• Random errors: errors that cannot be
explained by the forecast model being
used
• Measures of error
– Mean absolute deviation (MAD)
– Mean absolute percent error (MAPE)
– Tracking signal
LO 5
53. 14-53
The MAD Statistic to Determine
Forecasting Error
• The ideal MAD is zero which would
mean there is no forecasting error
• The larger the MAD, the less the
accurate the resulting model
MAD =

LO 5
54. 14-54
Tracking Signal
• The tracking signal (TS) is a measure that
indicates whether the forecast average is
keeping pace with any genuine upward or
downward changes in demand
• Depending on the number of MAD’s selected,
the TS can be used like a quality control chart
indicating when the model is generating too
much error in its forecasts
TS =
RSFE
MAD

Running sum of forecast errors
Mean absolute deviation
LO 5
56. 14-56
Causal Relationship Forecasting
• Causal relationship forecasting:
using independent variables other than
time to predict future demand
– The independent variable must be a
leading indicator
• Must find those occurrences that are
really the causes
LO 5
57. 14-57
Qualitative Techniques in
Forecasting
• Qualitative forecasting techniques take
advantage of the knowledge of experts
• Most useful when the product is new or there
is little experience with selling into a new
region
• The following are samples of qualitative
forecasting techniques
– Market research
– Panel consensus
– Historical analogy
– Delphi method

Web-Based Forecasting: (CPFR)
• Collaborative planning, forecasting, and
replenishment (CPFR): a Web-based tool
used to coordinate demand forecasting,
production and purchase planning, and
inventory replenishment between supply
chain trading partners
• Used to integrate the multi-tier or n-Tier
supply chain
• Objective is to exchange selected internal
information to provide for a reliable, longer
term future views of demand
• CPFR uses a cyclic and iterative approach to
derive consensus forecasts
