This paper summarizes brief perspectives on the historic process of establishing an African Crystallographic Association (AfCA) and includes representative references. It covers activities within four arbitrarily selected, approximate time slots, i.e., 1890s–1999, 2000–2013, 2014–2019 and 2020–2023. A genuine attempt is made to include appropriate role players, organizations and accompanying events within these periods. It concludes with the official admission of AfCA as the fifth Regional Associate of the IUCr at the 26th Congress and General Assembly of the IUCr in Melbourne, Australia in 2023.

Machine learning algorithms can sometimes do a great job with a little help from human expertise, at least in the field of materials science. In many specialized areas of science, engineering and medicine, researchers are turning to machine learning algorithms to analyze data sets that have grown too large for humans to understand. In materials science, success with this effort could accelerate the design of next-generation advanced functional materials, where development now usually depends on old-fashioned trial and error. By themselves, however, data analytics techniques borrowed from other research areas often fail to provide the insights needed to help materials scientists and engineers choose which of many variables to adjust -- and the techniques can't account for dramatic changes such as the introduction of a new chemical compound into the process. In a new study, researchers explain a technique known as dimensional stacking, which shows that human experience still has a role to play in the age of machine intelligence. The machines gain an edge at solving a challenge when the data to be analyzed are intelligently organized based on human knowledge of what factors are likely to be important and related. "When your machine accepts strings of data, it really does matter how you are putting those strings together," said Nazanin Bassiri-Gharb, the paper's corresponding author and a scientist at the Georgia Institute of Technology. "We must be mindful that the organization of data before it goes to the algorithm makes a difference. If you don't plug the information in correctly, you will get a result that isn't necessarily correlated with the reality of the physics and chemistry that govern the materials."

On dangerous or risky job sites, and within certain environments, personal protective equipment (PPE) must be worn at all times. It makes perfect sense, because the gear is designed specifically to mitigate severe or fatal accidents. Helmets, for example, protect the head from falling objects, overhead fixtures, and much more.

Roger Martin, professor emeritus at the University of Toronto's Rotman School of Management, says that for decades the U.S. corporate system has been obsessed with eliminating inefficiencies. There's a point, his research shows, when these efficiency gains come with even greater social and economic costs. And he believes that the Covid-19 pandemic is increasingly exposing those weaknesses. He argues that leaders and CEOs should reassess and, in some ways, reverse course in their perpetual drive for efficiency. Martin is the author of the new book "When More Is Not Better: Overcoming America's Obsession with Economic Efficiency."

Barry Nalebuff, professor at Yale School of Management and cofounder of Honest Tea, says too many companies shy away from cooperating with a competitor, and they’re leaving value on the table. He says even when working with other companies to find mutual benefits is not a clear win, cooperating may still be better than not cooperating. He shares how Honest Tea, Apple, Ford, and other firms analyze and capitalize on opportunities without giving up their secret sauce. Nalebuff is the author, with NYU Stern professor Adam Brandenburger, of the HBR article "The Rules of Co-opetition."

Kyle Jensen, associate dean at the Yale School of Management, has seen firsthand just how tempting it is for entrepreneurs to lie. As a startup founder himself, he says they have to be always "on" and ready to promote their venture. Another reason they’re incentivized to exaggerate is that while many startups fail, successes can become billion-dollar enterprises. Finally, Jensen argues, misrepresenting is relatively easy to get away with in a field of unproven potential. He talks through infamous examples of entrepreneurs distorting the truth and how to change startup culture for the better. Jensen is a coauthor of the HBR article "Entrepreneurs and the Truth."

You don’t have to be a famous author to suffer from writer’s block. We all can get stuck in our thought processes and mired in our actions. That's true for leaders and managers as well, explains Adam Alter, a marketing professor at the NYU Stern School of Business. He has studied how people hit plateaus or roadblocks in their work and careers. And he shares different methods for breaking free, including one proven tactic that seems very wrong: doing nothing. Alter wrote the new book Anatomy of a Breakthrough: How to Get Unstuck When It Matters Most.

It's easy to see how big stresses at work or home -- like layoffs, illnesses, or even a complex and important project -- cause anxiety too spike. But sometimes the stresses that cause the most hard are the tiny, everyday ones that build up over time into a much bigger problem because we don't take the time to recognize and manage our reactions to them. Former HBR editor Karen Dillon and Babson College professor Rob Cross studied the most common types of "microstress" and the ways in which they impact individuals, teams, and organizations. They explain why, if left unchecked, microstress can lead to mistakes, burnout, damaged relationships, and poor mental and physical health. But they also offer advice for better handling it -- and helping others to do the same. Dillon and Cross wrote the book The Microstress Effect and the HBR article "The Hidden Toll of Microstress."

In a globally connected and highly politicized world, organizations are increasingly expected to comment on social, political, and environmental issues. But taking a stance doesn't always make business sense and can backfire when employees or consumers see a disconnect between leaders’ words and actions. Alison Taylor, associate professor at New York University, says there's a better way to make decisions on corporate speech, which includes involving workers in the process. Taylor is the author of the HBR book Higher Ground: How Business Can Do the Right Thing in a Turbulent World and the HBR article “Corporate Advocacy in a Time of Social Outrage.”

Many managers struggle with initiating difficult conversations around an individual’s subpar performance. Often, leaders wait way too long to sit down with an employee who isn’t meeting expectations. Leadership coach Jenny Fernandez says that increasing the frequency of feedback and consciously developing better relationships with direct reports help make these conversations easier to start. And she shares how the right preparation, tone, and open-minded approach lead to more effective discussions that improve not just the one-on-one relationship, but also team morale and turnover rates. Fernandez is the author of the HBR article "How to Talk to an Employee Who Isn’t Meeting Expectations."

Are you the sort of person who works really hard, hits your deadlines, runs successful projects, wins over clients... but never seems to get noticed for all that diligence, much less promoted? Especially if you’re on the quieter and more understated side, working in an organization where the loud and showy get the most recognition, this can be frustrating. But there are ways to get noticed while also staying true to yourself, says Jessica Chen. She's a former TV news reporter and the founder of Soulcast Media, a communications consultancy, and she shares lessons about more effective communication and self-promotion. Chen wrote the book Smart, Not Loud: How to Get Noticed at Work for All the Right Reasons.
