The DEC Gaza appeal: why the BBC was right to refuse (guest blog)

When the BBC refused to show the Disaster Emergency Appeal for Gaza last year it was accused of cowardice and even partiality towards the Israelis. But is there an ethical and even humanitarian case for the line taken by the BBC in defence of its journalistic values? Polis Summer School student Lindsay Page here examines the moral arguments and asks whether the BBC actually made the right decision according to cosmopolitan principles

Feasibility of Fused Deposition of Ceramics with Zirconia and Acrylic Binder

Processing of ceramics has always been difficult due to how hard and brittle the material is. Fused Deposition of Ceramics (FDC) is a method of additive manufacturing which allows ceramic parts to be built layer by layer, abetting more complex geometries and avoiding the potential to fracture seen with processes such as grinding and milling. In the process of FDC, a polymeric binder system is mixed with ceramic powder for the printing of the part and then burned out to leave a fully ceramic part. This experiment investigates a new combination of materials, zirconia and acrylic binder, optimizing the process of making the material into a filament conducive to the printer system and then performing trials with the filament in the printer to assess its feasibility. Statistical analysis was used to determine optimal parameter levels using response surface methodology to pinpoint the material composition and temperature yielding the highest quality filament. It was discovered that although the mixture had adequate melting characteristics to be liquefied and printed into a part, the binder system did not provide the stiffness required to act as a piston to be fed through the printer head. Further studies should be completed continuing the investigation of zirconia and acrylic binder, but with added components to increase strength and rigidity of the filament

Advisor and Student Experiences of Summer Support for College-intending, Low-income high school graduates

Summer melt occurs when students who have been accepted to college and intend to enroll fail to matriculate in college in the fall semester after high school. A high rate of summer melt contributes to the lower postsecondary attainment rates of low-income students, in particular. This article presents qualitative findings from two interventions intended to reduce summer melt among low-income, urban high school graduates who had been accepted to college and indicated their intention to enroll. Results from student and counselor surveys, interviews, and focus groups point to a web of personal and contextual factors that collectively influence students' college preparation behaviors and provide insight into the areas of summer supports from which students like these can benefit. The data fit an ecological perspective, in which personal, institutional, societal, and temporal factors interact to affect students' behaviors and outcomes. A model of summer intervention shows that obstacles in completing college financing and informational tasks can lead college-intending students to re-open the question of where or whether to attend college in the fall after high school graduation. Given the pressure of concerns about how to actualize their offer of admission, students rarely engage in the anticipatory socialization activities that might help them make optimal transitions into college

More than Dollars for Scholars: The Impact of the Dell Scholars Program on College Access, Persistence and Degree Attainment

Although college enrollment rates have increased substantially over the last several decades, socioeconomic inequalities in college completion have actually widened over time. A critical question, therefore, is how to support low-income and first-generation students to succeed in college after they matriculate. We investigate the impact of the Dell Scholars Program which provides a combination of generous financial support and individualized advising to scholarship recipients before and throughout their postsecondary enrollment. The program's design is motivated by a theory of action that, in order to meaningfully increase the share of lower-income students who earn a college degree, it is necessary both to address financial constraints students face and to provide ongoing support for the academic, cultural and other challenges that students experience during their college careers. We isolate the unique impact of the program on college completion by capitalizing on an arbitrary cutoff in the program's algorithmic selection process. Using a regression discontinuity design, we find that although being named a Dell Scholar has no impact on initial college enrollment or early college persistence, scholars at the margin of eligibility are significantly more likely to earn a bachelor's degree on-time or six years after high school graduation. These impacts are sizeable and represent a nearly 25 percent or greater increase in both four- and six-year bachelor's attainment. The program is resource intensive. Yet, back-of-theenvelope calculations indicate that the Dell Scholars Program has a positive rate of return

How an artificially intelligent virtual assistant helps students navigate the road to college

Comprend des références bibliographiquesDeep reinforcement learning using convolutional neural networks is the technology behind autonomous vehicles. Could this same technology facilitate the road to college? During the summer between high school and college, college-related tasks that students must navigate can hinder successful matriculation. We employ conversational artificial intelligence (AI) to efficiently support thousands of would-be college freshmen by providing personalized, text message–based outreach and guidance for each task where they needed support. We implemented and tested this system through a field experiment with Georgia State University (GSU). GSU-committed students assigned to treatment exhibited greater success with pre-enrollment requirements and were 3.3 percentage points more likely to enroll on time. Enrollment impacts are comparable to those in prior interventions but with substantially reduced burden on university staff. Given the capacity for AI to learn over time, this intervention has promise for scaling personalized college transition guidance

Improving College Access in the United States: Barriers and Policy Responses

Socioeconomic gaps in college enrollment and attainment have widened over time, despite increasing returns to postsecondary education and significant policy efforts to improve access. We describe the barriers that students face during the transition to college and review the evidence on potential policy solutions. We focus primarily on research that examines causal relationships using experimental or quasi-experimental methods, though we draw upon descriptive evidence to provide context. Our review is distinctive in three respects. First, in addition to the literature on financial aid, we examine the evidence on informational and behavioral interventions, academic programs, and affirmative action policies intended to improve college access. Second, we incorporate a wealth of recent research not included in prior reviews. Finally, we conceptualize college access broadly, as including not just whether but also where students attend and whether they have access to college-level courses. We conclude with a discussion of implications for policy and research

In the Right Ballpark? Assessing the Accuracy of Net Price Calculators

Large differences often exist between a college’s sticker price and net price after accounting for financial aid. Net price calculators (NPCs) were designed to help students more accurately estimate their actual costs to attend a given college. This study assesses the accuracy of information provided by net price calculators. Specifically, we compare NPC estimates of financial aid to actual aid packages for a sample of low-income, first-time college students at seven postsecondary institutions which all utilize the federal template NPC. We find that NPC estimates of grant aid correlate highly with actual grant aid on average, but variation in individual financial aid packages among socioeconomically similar students can be substantial. We offer four recommendations. First, NPC aid estimates should include information on variability, and potentially, on sources of that variability. Second, a basic metric of academic merit such as SAT/ACT scores and GPA should be an optional addition to the federal template NPC. Third, institutions should update the data underlying their NPCs annually. Finally, we recommend that institutions use the “Explanations and Caveats” options on the federal NPC template to include additional information that may be helpful for students and families in anticipating their likely college aid and expenses. Our findings have implications for federal policy related to NPCs

Assessing Atlanta\u27s Place-Based College Scholarship

We investigate whether and how Achieve Atlanta’s college scholarship and associated services impact college enrollment, persistence, and graduation among Atlanta Public School graduates experiencing low household income. Qualifying for the scholarship of up to $5,000/year does not meaningfully change college enrollment among those near the high school GPA eligibility thresholds. However, scholarship receipt does have large and statistically significant effects on early college persistence (i.e., 14%) that continue through BA degree completion within four years (22%). We discuss how the criteria of place-based programs that support economically disadvantaged students may influence results for different types of students.https://scholarworks.gsu.edu/gpl_workingpapers/1003/thumbnail.jp

A study of kitsch in South African suburban society

Consider the possibility of the remnants of our present day society being excavated and studied in centuries to come. Imagine the craftsmanship, the art, artifacts and architecture that will then be compared to those of the past centuries. Our entire culture will be labelled by the endless array of rubbish that has become an integral part of our lives. The increasing prevalence of kitsch in the society goes almost unnoticed where it should be causing concern. Few people are aware of its existence, or the permanent aesthetic scars induced by this prevalence. How has this cult of sheer awfulness come about and why has it become prevalent? It is impossible to pursue all the avenues of kitsch - so vast is it but it is the purpose of this study to try and answer some of the questions, in order to make people more aware of what has crept into our society, to help them become more discriminating, and not merely to level criticism at the perpetrators of kitsch
