Professors research clarifies air pollution in CA and India


Faculty, students and staff gathered in the Martin Luther King, Jr. Library last Wednesday to listen in on the first presentation to kick-off the 13th annual University Scholar Series.

The presentation focused on economics professor Matthew J. Holian’s research on trends and relationships in California and India related to air pollution, regulations and economic growth.

Holian travelled to India to compare the trends and relationships in air pollution and its effects the economic growth of both India and California.  

"We downloaded air pollution data from monitoring stations that they (in India) have all of over the country and so we took the data and calculated city averages,” Holian said.And in some cities you have multiple monitoring stations and then we merged that air pollution data for cities to a bunch of other variables including income and literacy.”

He said the key question is what happens to pollution levels as income rises, because if people have more money they are buying more things which means they are polluting more.

According to Holian’s presentation, the whole scale of consumption goes up, but on the other hand people begin substituting for cleaner products when people have more money.

"That was really the key in the research, what's the effect of income growth on pollution,” Holian said. “We didn't find really clear evidence other than to say there is no clear relationship, it is complicated.”

Outreach librarian Elisabeth Thomas said the library works with the Office of the Provost and the Spartan Bookstore to bring speakers to demonstrate and honor professors’ extensive research.

“As a committee we come up with three speakers every semester,” Thomas said. “This semester it’s two speakers from different departments, faculty from different departments, and we want to showcase them and honor them for their extensive research that they do and have them come and speak and it’s hosted by the provost so we call it the Scholar Series.”

Thomas said other departments don’t realize all the work that other areas do and this event is a great chance for people to come together and showcase the work their department does.

“It’s really interesting, you get stuck in your own little niche on campus and it’s really nice just to see the vibrant and extensive work that we do,” Thomas said.

Among the members who attended the event, child development sophomore Annabelle Catolico  said she found the presentation interesting.

“I found it interesting on what he had to say about the south campus plan and how the grass he showed, was how greenhouse effect is going on and how transportation has increased since the 70s till now,” Catolico said.

Holian said the things Californians and the government are doing in California are putting us on the right track with the inclusion of state bill AB 32 with aims to reduce California’s greenhouse gas emissions.

"California is a leader in climate change mitigation in the United States,” Holian said. “I think it provides a lot of hope to a lot of people in the country and hopefully will serve as a role model for other people.”

The next Scholar Series event will be Oct. 28. Michael Kaufman is scheduled to present his research focusing on the interactions and feedback between newly formed stars and the interstellar medium.

Quakes score thrilling late equalizer on College Night

Photo by Jovanni Arroyo-Camberos The San Jose Earthquakes(2-2-2) are no stranger to late goals and in this game they needed some more of that magic as they drew 1-1 against FC Dallas (3-0-2) on Friday night. The Quakes celebrated a late equalizer in front of a crowd comprised of fans and students from colleges around the Bay Area for College Night. “I thought we played some good stuff [in the] first 30-35 minutes” Said San Jose Earthquakes head coach Dominic Kinnear. “I thought we looked pretty sharp moving the ball well, second half we came out and I thought we looked a little lackadaisical and they were getting chances because of that.”   The Earthquakes began the game with most of the possession. San Jose had several opportunities to get the ball into the back of the net but could not capitalize on their chances. In the 18th minute FC Dallas goalkeeper Jesse Gonzalez denied the Earthquakes the first goal of the match after forward Chris Wondolowski struck...

Attention turns to Oakland Raiders’ 2017 season home and away opponents.

With the light at the end of the tunnel coming down hard on what was much of a dream season for the Oakland Raiders, the team must now regroup, recover and prepare for next season. The NFL announced the Raiders’ home and away opponents for the 2017 season on New Year's day. And if the Oakland Raiders thought this was a dream season for them, they will need to pray for a miracle if they want to replicate this season's heroics starting in the fall. The NFL as a whole has a lot to look forward to, the Raiders on the other hand are matched up against not one, not two, but five teams that made the playoffs this year. The dates of each game for the 2017 season will be determined in April. A lot  can be speculated after the Raiders capped off the season with 12 wins and a playoff appearance, something the organization as a whole has not been able to do since 2000. Home Opponents: Denver Broncos, San Diego Chargers, Kansas City Chiefs, New England Patriots, Dallas ...

Infographic by Jovanni Arroyo-Camberos If anything was certain, it was that match six of the Copa America would be a high intense game that fans were looking for with this tournament. Although Barcelona superstar forward, Luis Suarez, was ruled out of the match because of a hamstring injury, the match still provided spectators with a lot of fireworks.

A crowd of 60,025 fans saw 37-year old and longtime Mexico captain, Rafael Marquez, score the go ahead goal securing three points and first place in the group for the team. “ I think we did a good job in the first half and we fell asleep a little in the beginning of the second half,” Marquez said in a postgame interview. “We reacted to their goal and we had much more confidence once we scored our second goal.” Mexico began the game with the fast-paced style offense coach Juan Carlos Osorio has brought ...
