Company Overview:
Company A has hired your team because you are experts in defining a process and delivering projects on time. Company A has only been in business for ten years, and they have experienced a large turnover in the project management area;which has prompted senior leadership to investigate.
Senior leadership has determined that Project Managers are frustrated with the amount of required documentation, which has impacted their ability to successfully manage projects. In addition, project budgets are coming in over budget, and projects are being delivered late, also resulting in PMs' inability to meet performance guidelines.
A recent review of the current process has determined that Company A has spent between 30-40% of its total project budget on projects' overhead costs to include project management costs, which are typically between 20-25%. Project Management overhead includes the PM's time to manage the project, attend meetings, and develop the required documentation.
Company A has hired your team to create a new project management process to meet the strategic goals and ensure the project meets the financial objectives.
Goals of the new process
The company must have a view into total life cycle project costs to include what has been spent to date, baseline budget, any changes to the budget, remaining budget, and cost of the project at completion
The company must have a view into the project activities to include what has been completed, what is remaining

Company Overview:
Company A has hired your team because you are experts in defining a process and delivering projects on time. Company A has only been in business for ten years, and they have experienced a large turnover in the project management area;which has prompted senior leadership to investigate.
Senior leadership has determined that Project Managers are frustrated with the amount of required documentation, which has impacted their ability to successfully manage projects. In addition, project budgets are coming in over budget, and projects are being delivered late, also resulting in PMs' inability to meet performance guidelines.
A recent review of the current process has determined that Company A has spent between 30-40% of its total project budget on projects' overhead costs to include project management costs, which are typically between 20-25%. Project Management overhead includes the PM's time to manage the project, attend meetings, and develop the required documentation.
Company A has hired your team to create a new project management process to meet the strategic goals and ensure the project meets the financial objectives.
Goals of the new process
The company must have a view into total life cycle project costs to include what has been spent to date, baseline budget, any changes to the budget, remaining budget, and cost of the project at completion

§ 2:3. General Restrictions on Freedom of Speech in Schools

The United States Supreme Court has recognized that "[t]he vigilant protection of constitutional freedoms is nowhere more vital than in the community of American schools."1 The Court has repeatedly noted the importance of First Amendment protection in the school context, although often at the same time recognizing the power of school officials to control conduct in the schools.2 The Court, in an oft-quoted statement, noted:
It can hardly be argued that either students or teachers shed their constitutional rights to freedom of speech or expression at the schoolhouse gate. This has been the unmistakable holding of this Court for almost 50 years … On the other hand, the Court has repeatedly emphasized the need for affirming the comprehensive authority of the States and of school officials, consistent with fundamental constitutional safeguards, to prescribe and contro.

State cultural agenda: After merger, it is important to state cultural objective and agenda in order to clarify the cultural expectations and to set a unified behavioral norm and pattern.
Encourage share values: It is not good to throw everything of pre-existing culture and change everything after merger (Shrivastava, 1986). It is better to work on the base of common operating principles and use the concept of shared values as well as standardized process.
Increase synergies: The basic logic behind merger of two companies is to increase the synergies through efficient operations. By combining the operations and values of two companies, a greater sum can be achieve (Søderberg & Holden, 2002).
Communicate expectations: By communicating expectations of merger with employees, a unified cooperating culture can be set (Kumar, 2000).

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.

He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

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.
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.

In a random sample of 35 tractors, the annual cost of
maintenance was $4,425 and the standard deviation was $775.
Construct a 90% confidence interval for this. Assume the annual
maintenance costs are normally distributed.
Answer:
90% = mean ± 1.645 SEm
5. SEm = SD/√n
I used the table in the back of my statistics text labeled "areas
under normal distribution" to find the proportion/probability
(±5%) to get Z = 1.645. I assume that you have a similar table
available.

For the following statements, state the null and alternative
hypotheses and identify which represents the claim. Determine
when a type I or type II error occurs for a hypothesis test of the
claim. Determine whether the hypothesis test is left-tailed,
right-tailed, or two-tailed, and explain your reasoning. Explain
how you should interpret a decision that rejects the null
hypothesis. Explain how you would interpret a decision that
fails to reject the null hypothesis.
