at davidson we work to make equal opportunity real. when we consider candidates for admission, we do so irrespective of their ability to pay and we meet demonstrated financial need for all admitted students through grants and campus. employment. i'm really privileged to be part of this group. i see myself in some sense as a bridge to higher education. so i'll talk about four roles that i hope to play on this council and four kinds of conversations that i hope i can inspire. first, i hope i can take the creative energy of this council back to the higher ed sector and inspire conversations in different parts of that sector about how we can ensure that all of our students continue the education and financial literacy and financial capability that they should begin as toddlers. second, i hope that we can convene conversations with partners through shared davidson's commitment to access, to make sure that talented kids understand how to get to college, how they can pay for college, why college is worth it and can chart a meaningful course f

davidson: business as usual is not really an option.nomy is based upon having tourists wanting to come here and spend time here. they're not gonna come here if the estuaries are full of algae that smell rotten. so it's extremely important, and we're getting to a tipping point where we have to do something. and i think the same is true across the globe. dudley: we know that people are still gonna want to come to the cape and that growth is gonna continue, so what we're really interested in trying to do is appropriately manage that growth. we believe that we can still save the habitat and that it isn't beyond a point of no return, and that's what we're actively trying to do. narrator: by combining census data with physical data collected in field studies, scientists can increase the accuracy of their models and help planners and policy makers prepare for future growth. dr. riche: what i do, essentially, is give people the base to look into the future, because we make connections between people and all these things that have costs. we will

mount davidson is also a great place to escape the noise and the bustle of the city. take the 36 bus and it will drop you at the entrance. it is quite a hike to the top but the view is worth every step. this is the place to bring that someone special. golden gate park's largest body of water is an enchanting place. is a popular spot for paddling around in boats, which can be rented. created in 1893, it was designed for these your boating -- for leisure boating. it is named for the wild strawberries that once flourished. there is also a waterfall, two bridges, and trails the climb to the summit, the highest point at more than four hundred feet. you can catch glimpses of the western side of the city that make this hilltop a romantic look out. for public transit, i take the n train. the lad the ad -- lake is ada accessible. watch many ducks, swans, and siegel's. -- seagulls. it is a great place to stroll and sail away. many couples come here to take a ride around a lake, going under the bridges, passing the chinese pavilion and the waterfall. for a quiet getaway, making

riding up harley davidson on the lp cover, i don't think he ever wrote a harley davidson in his life.laughter] somehow conductor as a between theonduit masters and the masterpieces and the mere mortals. this is a very disturbing image, actually. but somehow the sort of commercial parameters changed after the war. the whole industry became more backward looking, and that might have to do with the fact that lp changed the business. when lp became widely available, all of a sudden every household had access to these masterpieces. were a european or american household in the 1950's, when people started climbing up the ladder, what did they buy? piano was number car, and then access to masterpieces, the sort of series of books where you have the suit -- the place of shakespeare etc.. of being partea of contemporary culture disappeared out of that equation. i would say it is our fault as well because we kind of cultivated that image. i want to ask this question only because the next time i see you, or the next time you come on this program, i want to advance this conversation. you suggested

. >> hello, my name is jennifer davidson, i reside in the city. i'm a recently graduated interior designer and i also wanted to speak on the topic of the conversion to the office use because i have just gun to start my career in the design industry and i see this as an incredibly valuable resource for current and future designers and i feel that it would be damaging to remove that accessibility for incoming designers to learn more about their craft and to have contact with business people such as these in that space, which is currently very nice and is a historic spot, but the current business is important and future business as well. so i oppose the office allocation portion of this. >> thank you. any other member of the public wish /o speak. seeing none, we'll close public comment and bring back to commission. commissioner pearlman. >> thanks very much everybody for your presentation. i was the one who brought up the whole issue about losing the design showroom space and i didn't know mr. dixon, thank you for the information, if that's true abou

so davidson is committed to working with partners like the posse foundation and the college advising corps and ed ex and the college board and local schools. we work with cms to develop a pipeline to these talented kids that makes clear why college is affordable, why it's worth it and how their families can pay for it. third and i think most interestingly, you know, the economy is changing rapidly in ways that i need to understand more clearly than i do. and we in higher education need to make sure that the education we offer is actually worth what it costs given the world our kids will enter. our kids are entering a world that's very different from the one i entered when i graduated from the university of chicago, and they need to have had different classroom and experience cial opportunities for the four years that we at davidson have them so that they can succeed. so, for example, we need to make sure that our curriculum is student-centered and that from the moment our kids arrive on our campuses, they're grappling with questions so that they are prepared to create their own job o
