Operations management is important. It is concerned with creating the products and services upon which we all depend. And creating products and services is the very reason for any organization’s existence, whether that organization be large or small, manufacturing or service, for profit or not profit. Thankfully, most companies have now come to understand the importance of operations. This is because they have realized that effective operations management gives the potential to improve revenues and, at the same time, enables goods and services to be produced more efficiently. It is this combination of higher revenues and lower costs which is understandably important to any organization.

Operations management is also exciting. It is at the center of so many of the changes affecting the business world – changes in customer preference, changes in supply networks brought about by internet-based technologies, changes in what we want to do at work, how we want to work, and so on. There has rarely been a time when operations management was more topical or more at the heart of business and cultural shifts.

Operations management is also challenging. Promoting the creativity which will allow organizations to respond to so many changes is becoming the prime task of operations managers. It is they who must find the solutions to technological and environmental challenges, the pressures to be socially responsible, the increasing globalization of markets and the difficult-to-define areas of knowledge management.

(Text adapted from Teachers: 5 Tips for Creating Great PowerPoint Presentations, retrieved

   PowerPoint is a resource developed by Microsoft and released initially in 1990. It is mainly used in professional meeting presentations all over the world.

    One of these professions is in educational area: teacher.

    PowerPoint presentation is spread among teachers because it is different from lecturing or teaching with a textbook; it is also a way of sharing content with students.

    To produce a PowerPoint correctly, teachers need to know how to put the slides together, it can be an effective way of reinforcing content to students so that they are better able to retain it. Otherwise, teachers can print and distribute the PowerPoint presentation or post it online, so students can go back and access it as reference material. However, if it is not put together correctly, a PowerPoint presentation can disengage and make students bored.

   To develop PowerPoint presentation is simple and it can also provide a fun time noticed by its characteristics: basic, simple, and not distracting, it can be focused on keywords; for instance, always be sure to include a summary slide of what the presentation is intending to accomplish as well as a table of contents on the different topics that will be covered in the program. The summary slide serves as the main topic and what students should learn after viewing the presentation. Then, at the end of the PowerPoint presentation, teachers should include another summary slide, going over everything that was just covered and, again, highlighting the main point.

    PowerPoint presentations need to have a purpose and the teacher must make sure that the purpose is understood.

Add pictures

    Teachers can reinforce the content with pictures, charts, symbols, and other images. In fact, sometimes it’s better to have more pictures than text in a PowerPoint presentation, because images work to reinforce a content main point.

     Teachers typically will just share it with their classes, so they can pull images straight from the Internet. However, for teachers who are making more public and widespread presentations, copyright law needs to be considered (Brazil Information Access Law nº 12.527; Art. 31; paragraph 3; item II). 

      Pictures can help to reinforce a main point or support content, as well as videos. Some research affirm that students enjoy watching videos and retain information from them well, especially if the video is engaging, interesting and informative. Teachers can embed videos right from YouTube or from their desktops to complement a PowerPoint presentation.

      Nothing turns off a class like a poorly put together PowerPoint presentation, so teachers should always be sure to do a quick rehearsal before they present it to the class. While testing it, make sure all the images load up on the slides, videos load up properly and audio works, too. Also, it’s important for teachers to make sure that there’s a way to connect their computer, or upload anything that’s storing the PowerPoint presentation, to a larger TV monitor or projector screen so the whole class does not have to huddle around a computer screen to view it. Teachers should also make sure that any text can be read and understood. Be sure that the color scheme is good.

    A PowerPoint presentation can be an innovative way of teaching. It’s a more interesting and engaging way for students to learn than the typical lecture. Teachers should embrace this teaching resource and have fun with it. Throw in some jokes, possibly some funny pictures and be sure to get creative with presentations.

      As we previously noted, the more students enjoy a lecture, presentation, or activity, the more likely they are to retain information. 

“The current approach is bust,” said Prof Des Thompson, principal science adviser at NatureScot, Scotland’s conservation agency, which contributed to the declaration process run by the Scottish government. “What we need to do is work with local communities, local governments and local communities – that’s how we’re going to meet those targets.” (lines 9 – 12) 

City lawmakers in Brazil have enacted what appears to be the nation’s first legislation written entirely by artificial intelligence (AI) — even if they didn’t know it at the time.

The experimental ordinance was passed in October in the southern city of Porto Alegre and city councilman Ramiro Rosário revealed that it was written by a chatbot, sparking objections and raising questions about the role of artificial intelligence in public policy.

Rosário told The Associated Press that he asked OpenAI’s chatbot ChatGPT to craft a proposal to prevent the city from charging taxpayers to replace water consumption meters if they are stolen. He then presented it to his 35 peers on the council without making a single change or even letting them know about its unprecedented origin. The 36-member council approved it unanimously and the ordinance went into effect on Nov. 23.

The arrival of ChatGPT on the marketplace just a year ago has sparked a global debate on the impacts of potentially revolutionary AI-powered chatbots. While some see it as a promising tool, it has also caused concerns and anxiety about the unintended or undesired impacts of a machine handling tasks currently performed by humans.

Porto Alegre, with a population of 1.3 million, is the second-largest city in Brazil’s south. The city’s council president, Hamilton Sossmeier, found out that Rosário had enlisted ChatGPT to write the proposal when the councilman bragged about the achievement on social media. Sossmeier initially told local media he thought it was a “dangerous precedent.”

The AI large language models that power chatbots like ChatGPT work by repeatedly trying to guess the next word in a sentence and are prone to making up false information, a phenomenon sometimes called hallucination.

All chatbots sometimes introduce false information when summarizing a document, ranging from about 3% of the time for the most advanced GPT model to a rate of about 27% for one of Google’s models, according to recently published research by the tech company Vectara.

In an article published on the website of Harvard Law School’s Center of Legal Profession earlier this year, Andrew Perlman, wrote that ChatGPT “is a machine learning system, it may not have the same level of understanding and judgment as a human lawyer when it comes to interpreting legal principles and precedent. This could lead to problems in situations where a more in-depth legal analysis is required”.

There was no such transparency for Rosário’s proposal in Porto Alegre. Sossmeier said Rosário did not inform fellow council members that ChatGPT had written the proposal.

Rosário told the AP his objective was also to spark a debate. He said he entered a 49-word prompt into ChatGPT and it returned the full draft proposal within seconds, including justifications.

And the council president, who initially decried the method, already appears to have been swayed. “I changed my mind,” Sossmeier said. “I started to read more in depth and saw that, unfortunately or fortunately, this is going to be a trend.”
