Sales and operations planning a research synthesisWallace Almeida
Despite the growing body of literature on sales and operation planning (S&OP), efforts to synthesise the overall state of the art of research in this area are limited. Within this context, this paper provides a systematic review of the literature on S&OP. The purpose of this systematic review is twofold: (i) to integrate the highly dispersed work on S&OP in order to identify and analyse S&OP as a business process and (ii) to assemble quantitative evidence of its impact on the performance of the firm. A literature search framework is proposed, with 271 papers reviewed and classified. The framework embraces S&OP context information, inputs and goals, structure and processes, outcomes, and results. The major expected outcome in most papers was a cross-functional integration of plans, although few studies report on the integration of finance plans into S&OP. Despite the existence of common process descriptors and definitions of S&OP, there is a lack of unifying frameworks for maturity models, measurement of S&OP, and constructs related to the firm's performance. The need for additional scientifically sound survey or case study research on S&OP is emphasised. This paper contributes to a better understanding of S&OP's role as a determinant of firm's performance in the supply chain
Dissertation Windward Investment Management Case Analysis SampleDissertationFirst
This report analyzes an investment management firm, Windward. It is a well established registered investment advisor, which has been working as an independent money manager for its clients. The core client base of the firm consists of the high-net-worth individuals and the family offices. Windward Investment Management Company has witnessed a rapid growth in AUM (assets under management) in past 10 years, but now the company is considering a range of future growth opportunities and how to finance those opportunities, including raising external capital.
The case focuses on the decision of what opportunities, Windward should consider and on the valuation of the firm if it decides to raise external capital. For the purpose of deriving a structural analysis, report is divided in 6 chapters. Chapter one is of introductory chapter. This chapter acquaints the reader with the background of the study. Here the statement of problem, aims and objectives of the study and a detailed synopsis of the entire report's structure has been disclosed. Beginning of the chapter sketches the pertaining business process, client base, situation, working etc at Windward.
In the second section case description is given. Here a detailed picture of the case has been drawn. This chapter gives details regarding the company, company's management, business process, its evolution, industry etc. This chapter provides ground to the entire study.
Statement of problem backed by the case brief will be defined in this section of the report. All the relevant concepts and theories will also get introduced and discussed here only. Such discussion will be termed as the literature review of the topic. Further a detailed plan for analysis will be carried out along with defining the most appropriate sources of data for the study. Through data analysis in accordance with the proposed plan of analysis, assessment of the current position of the firm will be done and further the prospective strategies for the firm will be derived.
In the fifth section of the report a detailed and integrated analysis of the findings will be done. Through the discussion, recommendations for Windward will be scaled out. On the basis of the recommendations and discussion a plan of action will be proposed with a rigorous discussion on the limitations of the study conducted or the derived results. Further the chapter will end with discussions on the scope of further studies. Sixth chapter will be concerned about the utility of the study for the other players of some other industries. Here, the learning of the entire analysis will be briefed and applied on any other industry unit.

4. Monday October 27 lecture
Themes: Global Media Governance and Regulation; The Internet and Digital Media
Readings: Chapter 5, “The Medium: Global Technologies and Organizations,” and Chapter 6, “The Internet”
In this lecture, we discussed the definition and history of communication rights as one element or dimension of communication policy, and used it to bring to life a subject—policy—that sometimes seems abstract and technical in nature.
In doing so, we noted the evolution from a “negative” rights view of communication rights, as expressed in Article 19 of the United Nations Universal Declaration of Human Rights in 1948, to the more “positive” definition of communication rights explained in the lecture content derived from the work of Marc Raboy (and Jeremy Shtern).
Remember that “negative” does not mean “bad” here nor “positive” good. “Negative” and “positive” rights—which are ways of thinking about all human rights, not just communication rights—are instead ways of characterizing the orientation of rights toward individuals and society. Negative rights are defined in terms of freedom
from
things, and positive rights in terms of freedom
to
have or do certain things. Both negative and positive rights derive their legitimacy from fundamental and universal consideration of what it means to be human and to be treat people as human beings.
In our case study at the end of the lecture, we then discussed how a “positive” approach to communication rights could help us better understand and perhaps act against cyberbullying.
In your paper, and in your own words, define “communication rights,” and then briefly explain the evolution from the negative to the positive rights approach to communication rights.
Once you have done that, and with reference to the cyberbullying pamphlet from the Canadian government attached to your lecture notes, demonstrate how a “positive” rights approach to communication rights can help us better understand and prevent cyberbullying. In other words, what are the limitations of approaching cyberbullying from a “negative” rights perspective, and what does a “positive” approach to communication rights do to help us understand and perhaps act against cyberbullying?
Cyberbullying is a problem in international communication that affects many, especially vulnerable teenagers, as illustrated in the case of the late Amanda Todd (from British Columbia).
You do not need to use the McPhail chapter here, as it is not directly relevant to this question. Rather, draw on the lecture notes and the podcast as your sources here.

EXAMPLE QUESTIONS ..........
What’s your first, most vivid memory? Going to my grandma and grandpa’s farm and making grandma walk me out to the outhouse for fear of a mean bannie rooster would peck me to death. He was afraid of grandma.
What was the apartment or house like that you grew up in? How many bedrooms did it have? Bathrooms? I lived with my mother and father mostly in a house in the city that had 2 bedrooms, 1 bathroom. I had to share a room with my older brother that was upstairs.
What was your bedroom like? Very simple. It had 2 beds made of feathers, a desk with a lamp and one dresser for our clothes. Dallas (my brother got the bottom 2 and I got the top 2)
Can you describe the neighborhood you grew up in? Not really. Every chance I got I went to grandma and grandpas and spent time with them. They lived deep in the country. I had one friend out there that lived about 3 miles away on the next farm. His name was Carl.
Tell me about your parents. Where were they born? When were they born? What memories do you have of them? Both parents were born in Richmond, IN. Memories include more of my mother than my father. He was a drunk that stayed out all the time. He only came home when he was ready to pass out or to beat us.
Who was more strict: your mother or your father? Do you have a vivid memory of something you did that you were disciplined for? Since mom was the main one around I would say that she was more strict. I remember one instance when I was about 16 and mom had kicked me out of the house because she was forced to work with dad being gone all the time and I was telling her that I no longer wanted to take care of my little brother because I felt like I was his mother rather than her and that I didn’t want to do anymore of the house work. It was her house she should have to clean it. She kicked me out. I was sitting on the porch crying and dad came home (sober for once) and sat on the porch with me, got me calmed down and offered to give me a ride to grandma and grandpa’s.
Did your parents have a good marriage? No they had a horrible marriage.
How did your family earn money? How did your family compare to others in the neighborhood – richer,
poorer, the same? My family earned money from my mother working in a diner. Dad worked in a mill but we rarely saw his money. We did alright but I would say that we were on the poorer end of society.
What kinds of things did your family spend money on? The necessities and that was it.
How many brothers and sisters do you have? When were they born? What memories do yo.

You are the vice president of a human resources department and Susan has been your executive assistant for one (1) year. She effectively completes her given assignments, sometimes ahead of schedule. Susan has a welcoming personality and is commended on her willingness to help when asked. As a result of her efficiency, Susan often has spare time on her hands.
In several conversations, you have spoken with Susan about taking a proactive stance and involving herself in the business to increase her knowledge base.

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.

A Strategic Approach: GenAI in EducationPeter 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.
