Out-Of-School Factors and School Success
Poverty and Potential: Out-of-School Factors and School Success David C. Berliner Regents’ Professor Arizona State University March 2009 The Great Lakes Center for Education Research & Practice PO Box 1263 East Lansing, MI 48826 Phone: (517) 203-2940 Email: [email protected] Web Site: http://www.greatlakescenter.org One of a series of Policy Briefs made possible by funding from the Great Lakes Center for Education Research and Practice. This policy brief was peer reviewed by members of the EPIC/EPRU Editorial Review Board. For information on the board and its members, visit: http://epicpolicy.org/editorial-board. Poverty and Potential: Out-of-School Factors and School Success David C. Berliner Arizona State University Executive Summary The U.S. has set as a national goal the narrowing of the achievement gap between lower income and middle-class students, and that between racial and ethnic groups. This is a key purpose of the No Child Left Behind act, which relies primarily on assessment to promote changes within schools to accomplish that goal. However, out-of-school factors (OSFs) play a powerful role in generating existing achievement gaps, and if these factors are not attended to with equal vigor, our national aspirations will be thwarted. This brief details six OSFs common among the poor that significantly affect the health and learning opportunities of children, and accordingly limit what schools can accomplish on their own: (1) low birth-weight and non-genetic prenatal influences on children; (2) inadequate medical, dental, and vision care, often a result of inadequate or no medical insurance; (3) food insecurity; (4) environmental pollutants; (5) family relations and family stress; and (6) neighborhood characteristics. -
Sarah Friar the Empathy Flywheel, W/Nextdoor CEO
Masters of Scale Episode Transcript – Sarah Friar The Empathy Flywheel, w/Nextdoor CEO Sarah Friar Click here to listen to the full Masters of Scale episode featuring Sarah Friar. REID HOFFMAN: For today’s show, we’re talking with Sarah Friar, the CEO of Nextdoor, who’s built a reputation in Silicon Valley as both a skilled operator and a beloved leader. But we’ll start the show – as we often do – by hearing from another person who’s renowned in their field. DR. ROBERT ROSENKRANZ: I might not be Mark Zuckerberg, I might not be Sheldon Adelson, I might not be Tom Brady, all right. I'm Robert Rosenkranz, I'm a dentist in Park Slope, and I love my patients. I love what I do. HOFFMAN: Robert Rosenkranz is a dentist in Brooklyn, New York. A dentist who loves his patients so much he sees 80 of them every day. That means he’s in the office almost 14 hours, six days a week. ROSENKRANZ: Okay. A little less on Sunday. Otherwise my wife would leave me. But six days, we're looking like max hours. Max capacity. HOFFMAN: You know the drill on this show. Working long hours isn’t unusual. What sets Robert’s dental practice apart is that his patients keep multiplying. Not because the good people of Park Slope have particularly bad teeth, but because they just love visiting Robert. ROSENKRANZ: One of my very good friends says to me, “Whenever you see someone, they think you're their best friend. When you talk to them, they feel like you're their best friend." I said, "That's what I want." I take that, and I bring it to work, and I bring it to strangers, and it becomes infectious. -
Social Influence in Social Advertising: Evidence from Field Experiments
Social Influence in Social Advertising: Evidence from Field Experiments EYTAN BAKSHYy, Facebook DEAN ECKLESy, Stanford University & Facebook RONG YAN, Facebook ITAMAR ROSENN, Facebook Social advertising uses information about consumers’ peers, including peer affiliations with a brand, prod- uct, organization, etc., to target ads and contextualize their display. This approach can increase ad efficacy for two main reasons: peers’ affiliations reflect unobserved consumer characteristics, which are correlated along the social network; and the inclusion of social cues (i.e., peers’ association with a brand) alongside ads affect responses via social influence processes. For these reasons, responses may be increased when multiple social signals are presented with ads, and when ads are affiliated with peers who are strong, rather than weak, ties. We conduct two very large field experiments that identify the effect of social cues on consumer responses to ads, measured in terms of ad clicks and the formation of connections with the advertised entity. In the first experiment, we randomize the number of social cues present in word-of-mouth advertising, and measure how responses increase as a function of the number of cues. The second experiment examines the effect of augmenting traditional ad units with a minimal social cue (i.e., displaying a peer’s affiliation below an ad in light grey text). On average, this cue causes significant increases in ad performance. Using a measurement of tie strength based on the total amount of communication between subjects and their peers, we show that these influence effects are greatest for strong ties. Our work has implications for ad optimization, user interface design, and central questions in social science research. -

Understanding Individuals' Attachment to Social Networking Sites

With greater connectivity and interactivity enabled via web technologies, SNSs provide communication platforms for individuals to bridge geographical and temporal differences when making friends, sharing experiences, socializing with others and much more. This thesis therefore endeavors to shed light on this problem by decomposing members’ motives for participating within SNSs into identity-based, bond-based and comparison- based attachments. Each of these forms of attachment in turn affects members’ cooperative and competitive mentality towards participation within SNSs. In addition, it is further posited in this thesis that members’ identity-based, bond-based and comparison- based attachment within SNSs can be induced through the presence of deindividuation, personalization and tournament technologies respectively. -

How Do People Display Social Networks in Everyday Life (That Is, Not Online)? Give 2 Concrete, Specific Examples
How do people display social networks in everyday life (that is, not online)? Give 2 concrete, specific examples. Why do they do this? Looking at this display as a signal, what is the quality it is inferring? What are the costs of making this signal? The benefits? Is there a cost to the receiver if it is not honest? One way people display social networks to others is by dropping names. For example, someone could say “I was talking to Alex Rodriguez the other day…” In these cases, signaling this information is meant to either attach oneself to a respected other or signal importance outright. While there are few costs associated with the actual creation of such a signal, the benefits normally involve an elevated level of respect (“Wow, Bob must be cool if he knows A-Rod!”). If the signal is discovered to be false, however, there could be severe social repercussions ranging from a public ridiculing to ostracism. From the receiver’s point of view, they may stand to be taken advantage of by the deceptive signaler in the form of underserved respect that may be abused by the signaler. Another display situation is when individuals use their social connections to help their friends. If someone gets their friend a job at their company they are displaying their social connections both to their friend and employer. Not only does this have the benefit of helping a friend, but it increases their standing with their employer, especially if the friend turns out to be a good employee. This action requires some amount of social capital, since the recommender is effectively extending their reputation to encompass their friend, and this reputation could be severely harmed if the friend does not work out as an employee.
