When Iowa's motor-fuel tax increased by 10 cents a gallon on March 1, it represented a road that was both brave and opportunistic.

It was also stupid, for two key reasons: Raising the gas tax doesn't fully address the funding need for critical road improvements, and over time it will provide less and less money while road-construction costs continue to increase.

Despite that, the hike was still brave, because raising taxes is never popular among voters - especially when they feel the pain every time they visit the gas pump. The Des Moines Register has polled Iowans about a gas-tax hike for the past five years. While the amount of the hike in the question has varied over the years, opposition to an increase was 70 percent in 2011. Opposition has eroded since then, but it was still 58 percent in February 2014.

Which leads us to opportunistic. Mirroring national trends, from July 2014 to early 2015 gas prices dropped from more than $3.50 per gallon in the Quad Cities and Des Moines to under $2, according to GasBuddy.com.

Prices have risen since then but are still more than a dollar cheaper than in mid-2014, so legislators saw a window of opportunity. The February 2015 Des Moines Register poll found 48 percent support for a 10-cent gas-tax hike and only 50 percent opposition - and the cost of fuel was certainly a factor in that shift.

The timing was great in political terms, too, just after a statewide-election cycle. The problem of deteriorating roads and bridges - and the choice for a solution - had been on the table since late 2011, but there's nothing like the longest period of time before an election to spur legislators into unpopular action.

Since 2005, the Arab Barometer project that Amaney A. Jamal co-founded has interviewed ordinary people in the Arab world about their views on (according to ArabBarometer.org) "governance, political life, and political, social, and cultural values."

So Jamal had extraordinary insight into the Arab Spring that began in 2010, and its aftermath. In a phone interview last week, she said she had seen the seeds of change but didn't know if or when they would blossom. "It was very clear and obvious in our public-opinion polls that the status quo was not sustainable," she said. "That the levels of frustration, the levels of mass discontent with the status quo were there. What was not clear was whether ... there was going to be some sort of trigger to bring it all down."

Jamal will present "The Arab Spring: Did All Go Wrong?" - St. Ambrose University's Folwell Lecture in Political Science & Pre-Law - on February 9, and the answer to that question should be obvious enough to anybody who pays attention to international news.

Jessica Lamb-Shapiro's Promise Land seems to invite preconceptions.

First, there's the white kitty hanging perilously from a rope on the book cover, cheekily recalling the famous "Hang in There" inspirational poster.

Then there's the subtitle: My Journey Through America's Self-Help Culture.

Flip to the first page of prologue. The book opens: "Ten years ago, I tagged along with my father to a weekend conference on how to write self-help books." Yes, it really was a self-help retreat for self-help-guru wannabes.

From those elements, you might expect an arch, cynical take-down of a movement and the industry that feeds it (or feeds off it).

Lamb-Shapiro will be the January 27 guest in the River Readings at Augustana series, and you're hereby advised to not judge this book by its cover or its opening sentence. It's so much richer than that.

The 2009 book Half the Sky is filled with stories that are heartbreaking and inspiring - and often both. The Pulitzer Prize-winning husband-and-wife team of Nicholas D. Kristof and Sheryl WuDunn gives you precisely what you'd expect from a book subtitled Turning Oppression Into Opportunity for Women Worldwide. There are lots of anecdotes supporting the idea that women across the globe face horrific violence, discrimination, and marginalization. That's countered by personal stories that provide hope for change. And both are supported by statistics and academic studies.

"We think that one of the greatest moral challenges of our time is the gender inequality and the brutality that many women and girls face around the world because of their gender," said WuDunn - who will present a lecture version of the book on October 21 at St. Ambrose University - in a recent phone interview. "We also think one of the most effective ways to address a lot of the inequality is through educating girls and bringing them into the formal labor force ... . And we talk about a lot of these issues by telling stories of women who have been facing these challenges, and of other women and men who have come up with solutions."

But the book is also surprising - in ways that are both very small and very big.
