CEP: YPOV - Preparing for Chairing? Build Some Relationships!

March
2014
YPOV
Meagan Lewis
Programming for an AIChE conference — i.e., developing the technical program — takes a lot more than the work put in by the meeting chairs; the details and ideas that go into every session and its roster of speakers take a whole force of volunteers. As a co-chair for the upcoming 2014 Spring Meeting in New Orleans who also happens to be a young professional (YP), I’ve realized that the best way to prepare for programming a large-scale conference is to build relationships across all levels of the organization.

When I bought my iPad a few years ago, I was looking forward to accessing a library of books without lugging around the weight. And reading the newspaper online would keep the newsprint from dirtying my hands. Now that I’ve had the iPad for three years, though, I see that my expectations were not realistic. Yes, I can access books and newspapers on my iPad. But actually reading them is another matter.

CEP: Editorial - Engaging in Public Affairs

February
2014
Editorial
Cynthia Mascone
As a student unsure of what chemical engineers actually did in the real world, I wondered whether I would like being a chemical engineer. A double major, I reasoned, would provide a safety net — just in case. Students in the engineering and public policy (EPP) department worked on projects at the intersection of technology and society, like energy, the environment, and risk analysis. Those sounded interesting, so I enrolled in the ChE/EPP double-major program. Electives on topics such as energy policy, organizational behavior, social analysis, and arms control and defense policy, and projects on product liability, diagnostic radiation, and coal mine safety, gave me an appreciation for the interdependence of engineering and the public welfare.

CEP: Commentary - Educating Students to Become Engineers

June
2014
Commentary
R Russell Rhinehart
The article “How Well Are We Preparing ChE Students for Industry?” in the Update section of the April issue of CEP (pp. 4–5, 14–15) meshed with my career-long concern about engineering education. I graduated in 1968, with pride in my skills, from “a strong program” that “was about to break into the top ten,” as we were told. It was a good program in many ways, but after two years in industry, I came to realize the misdirected perspectives I had acquired as a student. After 13 years in industry and 28 in academia, I have concluded that neither the academic perception of excellence nor the tasks students are required to complete align with the perceptions and tasks that lead to success in industry.

CEP: Editorial - It’s All About the Culture

Cynthia Mascone
December 3 marks the 30th anniversary of the worst chemical accident in history — the catastrophic release of methyl isocyanate (MIC) from a pesticide plant in Bhopal, India, in 1984 that resulted in thousands of deaths and hundreds of thousands of injuries. Two articles and the Process Safety Beacon in this issue review some of the lessons learned from that tragic incident.

CEP: Career Corner - Is Starting a Consulting Practice Right for You?

June
2014
Career Corner
Loraine Kasprzak
Are you considering starting your own engineering consulting practice? One of my best career moves was leaving my corporate position to open my own consulting firm. Perhaps, like me, you were bitten by the entrepreneurial bug, or perhaps your current employer is downsizing and a severance package will provide you with the opportunity you have been waiting for — not to mention the cash reserves you need to get through your first year. Consulting may seem like a glamorous career, one in which you get to work when you want and make lots of money. Nothing could be further from the truth. You must be able to work without having the structure and accountability that being employed by someone else provides.

CEP: Editorial - Getting ChE Education Right — Part 2

June
2014
Editorial
Cynthia Mascone
Our discussion of chemical engineering education began in the April issue, with the news story “How Well Are We Preparing ChE Students for Industry?” and my editorial, “Getting ChE Education Right.” This month, we look at education again, with two more articles. The April articles resonated with Russ Rhinehart, a professor at Oklahoma State Univ., and inspired him to write a letter to the editor, which became this issue’s Commentary, “Educating Students to Become Engineers” (pp. 14–15). By coincidence, the AIChE Journal Highlight, “A Broader Role for the Evolving Engineer” (p. 13), also focuses on education.

Although I recently returned from a vacation and would love to tell you about the hiking we did, that’s not the topic of this editorial. Previously, I wrote about jump-starting creativity through relaxation and trying something new (Dec. 2013) and by incorporating play into your day (Jan. 2014). Here’s another powerful creativity booster to add to your toolbox — walking. Your walk doesn’t have to be an eight-mile trek from the Colorado River at the bottom of the Grand Canyon to the rim nearly a mile higher. Walking can be as simple as doing laps around the office, or getting off the bus or train a stop or two early and walking the rest of the way to your destination.

CEP: Editorial - Getting ChE Education Right

Cynthia Mascone
When I was in college, I earned some spending money as a shoe model for a local freelance photographer. Little did I know I would become a cover girl. But a few years later, shortly after I began my career as an editor (at a different magazine), I was tapped for just that role. Wearing a black cap and gown and photographed looking out into a maze of piping in a chemical plant, I represented a young graduate facing my first job in industry. The cover line — “Chemical engineering education: How good is it, really?” — referred to an article that discussed the results of a reader survey conducted by two of my colleagues. That was 31 years ago. Today, we are still pondering the same question.

Louisa Nara
One of my favorite warm weather activities is kayaking. The river provides a respite away from crowds and electronic distractions. Daily stressors are erased by the warm sun, a light breeze, and the sound of water lapping at my boat. A recent weekend with great weather afforded the perfect opportunity to go out on the river with my husband. Earlier that week, severe storms blew through the area with significant rainfall and flash flooding. This increased the volume of water in the river, so conditions would be perfect for a fast and exciting ride. It also called for a more-mindful approach to safety hazards, like swift currents and debris in the water.

CEP: Spotlight on Safety - Discover Your Personal Process Safety Culture

February
2014
Spotlight on Safety
John Herber
Culture can be defined as a collective group of shared beliefs and values that shape how we act. We think of culture as it relates to the actions and reactions of a group, company, or society. However, it can also characterize an individual — what influences how you make day-to-day decisions or handle various situations. Personal process safety culture can be assessed by observing someone’s (yours or another person’s) response to situations involving a safety violation.

CEP: Editorial - Get Smart about Electricity

August
2014
Editorial
Cynthia Mascone
According to the Edison Foundation, nearly 40% of U.S. households, about 46 million residences, are outfitted with a smart meter for monitoring and managing electricity use. Some of these meters operate under direct load control (DLC), which allows the utility to intermittently interrupt service to connected appliances — such as electric heaters, central air conditioning systems, water heaters, hot tubs, and clothes dryer heating elements — during periods of peak electricity demand. In return for their willingness to accept these short (typically no more than a few hours) power interruptions, customers receive a payment or a credit on their electric bill. Smart metering is a form of demand-side management, and is an important part of the evolving smart grid.

We all have limits to our abilities. Some of us stumble over our words and lose our train of thought when speaking to a group; others can’t string together three coherent sentences. Some of us get so bogged down in minutiae that we lose sight of the big picture; others are so busy dreaming up the next project that we neglect important details and miss deadlines. This thinking extends to physical characteristics. Some of us are so short that we can’t reach the second shelf in the cabinet; others are so tall that we can’t fit into the backseat of a car.
