3 . Reasons why you should learn how to surf

The feeling of riding the waves is one you can never describe until you have experienced it. While surfing, you’ll be in a peaceful state as you wait for the next big wave. It can be difficult to explain why, but the whole experience is indeed calm and exciting at the same time.    1    , as if you’re running away from all your worries in life.

Surfing is a physically challenging sport that requires you to use your entire body, making it almost an extreme fitness activity. Every surfing session will certainly make you exercise your whole body. So, expect to have aching muscles after your first surfing session.     2    

There is no denying the fact that healthy and fit people are confident with their bodies.    3    Nevertheless, surfing promotes confidence that isn’t necessarily rooted in how you look or boost your ego (自我). It takes time to learn and even master.

Learning a new skill with a group leads to a sense of accomplishment, and learning how to surf is no different. Although it’s natural to go surfing alone at times, no surfer has surfed without acquaintances (熟人), friends, or club mates. It’s a given for people who surf to share experiences with others, both locally and globally.

Like some other sports, surfing allows you to have time with nature.    5    With surfing, you’re able to observe nature from a different viewpoint. This is an ideal time to be one with nature, so grab the chance to broaden your horizons (视野) as a part of this beautiful planet we live on.

5 . Advances in AI and machine learning have sparked interest from governments that would like to use these tools for patrolling (巡查) purposefully before hand to prevent crime. However, early efforts at crime prediction have been controversial, because they do not allow for systematic biases (偏见) in police enforcement and its complex relationship with crime and society.

University of Chicago (UC) data and social scientists have developed a new algorithm (算法) that forecasts crime by learning patterns in time and geographic locations from public data on violent and property crimes. It has demonstrated success at predicting future crimes one week in advance with approximately 90% accuracy.

The new tool was tested and validated using historical data from the City of Chicago around two broad categories of reported events: violent crimes and property crimes.

The new model isolates crime by looking at the time and spatial coordinates (坐标) of separate events and detecting patterns to predict future events. It divides the city into spatial sections roughly 1,000 feet across and predicts crime within these areas instead of relying on traditional neighborhood or political boundaries, which are also subject to bias. The model performed just as well with data from seven other US cities.

Ishanu Chattopadhyay, senior author of the study, is careful to note that the tool’s accuracy does not mean that it should be used to direct law enforcement, with police departments using it to flock to neighborhoods ahead of time to stop crime. Instead, it should be added to a toolbox of urban policies and policing strategies to address crime.

“We created a digital twin of urban environments. If you feed it data from what happened in the past, it will tell you what’s going to happen in future. It’s not magical; there are limitations, but we tested it and it works well,” Chattopadhyay said. “Now you can use this as a model tool to see what happens if crime goes up in one area, or there is increased enforcement in another area. If you apply all these different data, you can see how the system evolves in response.”

6 . In an increasingly globalized business world, companies demand Human Resources (HR) leaders who can overcome cultural barriers to achieve key goals. This year, students in the Master of Human Resources and Industrial Relations (MHRIR) Program will get hands-on experience leading multicultural teams as they work together with peers (同辈) from all corners of the globe.

“Our students get firsthand experience on global teams, which helps them understand the challenges and the opportunities they will face in the business world,” said MHRIR Program Director Stacy Hove.

Elishka Correa joined the program to explore how HR leaders can help businesses grow quickly in the global marketplace. “Companies appreciate diversity — not only in terms of products and markets, but the people they hire — so that they can expand their business and reach customers in different parts of the world,” she said. “When I go into an organization, I’m not only going to work with Indians or Americans, it’s going to be a mix of people. That trend is beginning to grow, so I think it’s very important to appreciate people from different backgrounds.”

As they progress through the program, the students are discovering unexpected challenges as they work on projects in diverse teams. Each contributor brings a different approach to solving problems, communicating, and challenging one another’s opinions.

Devin Roll, a student from North Dakota, appreciating the unique views his classmates share, said, “The benefits of having cross-cultural experiences go far beyond the classroom. Diverse teams and companies outperform their competitors, and HR leaders act as a vital partner in acquiring and maintaining diversity in the workforce.”

Many of the international students in the program said they would return to their home countries after graduation and bring along connections to their classmates, who would build careers (职业) in countries around the world. They hope to stay in touch, and share their expert knowledge.
