The four central chapters explore four themes: history, as the foundation for the state; rapid development under military dictatorship; urban space and its architecture of non-descript boxes; the ...digitized city where physical and virtual worlds merge. In chapter 3, King convincingly argues that today's Seoul is Park Chung Hee's memorial, with its architecture balanced between a dominant modernity and an occasional nod to Korean heritage, the latter having much to do with the late founder of the organization Space, Kim Sugŭn. I have minor quibbles: in describing the "poor south," King fails to distinguish the more prosperous, developed southeastern Kyŏngsang provinces—directly across the sea from Japan, the home region of Park—from the less prosperous, backward, agricultural southwestern Chŏlla provinces; Bukhansan (a.k.a. Pukhansan) and Pugaksan (a.k.a. Bugaksan), contrary to page 103, are not two different mountains, since the second is part of the first; contrary to page 104, nothing of Seoul's subway lines 2, 3, and 4 began operating in the 1970s. King argues that Seoul's identical high-rise concrete-block apartments encourage the virtual world by reducing day-today interaction, selecting a few choice films, songs and novels (including, prominently, a dystopian work by a British author) to establish notions of assemblage, now in the identity-free rhizome rather than any residual geographical place marked "Seoul."
Natural killer (NK) cells are an important component of the immune response to a number of viruses; however, the molecular basis of how NK cells discriminate between healthy and virus-infected cells ...is largely unknown. Here, we show that expression of the immediate-early gene product ICP0 is sufficient to produce an increased susceptibility to NK lysis of herpes simplex virus (HSV)—infected cells. This effect does not depend on downregulation of major histocompatibility complex class I molecules or on the induction of expression of ligands for the activating NKG2D receptor. Detection by NK cells of the changes in the target cell induced by HSV ICP0 gene expression depends on the natural cytotoxicity receptors (NCRs) NKp30, NKp44, and NKp46. To our knowledge, this is the first identification of a viral gene that triggers the up-regulation of cellular ligands for the NCR; moreover, these observations highlight the importance of the NCR for immunosurveillance of viral infection by NK cells.
The use of modeling projects serves to integrate, reinforce, and extend student knowledge. Here we present two projects related to tumor growth appropriate for a first course in differential ...equations. They illustrate the use of problem-based learning to reinforce and extend course content via a writing or research experience. Here we discuss methods of preparing students for a research/writing experience, the critical thinking involved in completing the project, and the basic assessment of student work.
In this article, the authors use the High School Longitudinal Study 2009 (HSLS:09) national database to analyze the relationships between algebra failure, subsequent performance, motivation, and ...college readiness. Students who failed eighth-grade Algebra I did not differ significantly in mathematics proficiency from those who passed lower-level courses, but initially demonstrated significantly lower mathematics interest, mathematics utility, and mathematics identity. Both groups were less likely than the general population to meet college requirements in the eleventh grade, although students who passed a lower-level mathematics course fared better than those who failed Algebra I. Implications for policies addressing mathematics course enrollments are discussed.

Behind every financial crisis lurks a "political bubble"--policy biases that foster market behaviors leading to financial instability. Rather than tilting against risky behavior, political ...bubbles--arising from a potent combination of beliefs, institutions, and interests--aid, abet, and amplify risk. Demonstrating how political bubbles helped create the real estate-generated financial bubble and the 2008 financial crisis, this book argues that similar government oversights in the aftermath of the crisis undermined Washington's response to the "popped" financial bubble, and shows how such patterns have occurred repeatedly throughout US history.
The authors show that just as financial bubbles are an unfortunate mix of mistaken beliefs, market imperfections, and greed, political bubbles are the product of rigid ideologies, unresponsive and ineffective government institutions, and special interests. Financial market innovations--including adjustable-rate mortgages, mortgage-backed securities, and credit default swaps--become subject to legislated leniency and regulatory failure, increasing hazardous practices. The authors shed important light on the politics that blinds regulators to the economic weaknesses that create the conditions for economic bubbles and recommend simple, focused rules that should help avoid such crises in the future.
The first full accounting of how politics produces financial ruptures,Political Bubblesoffers timely lessons that all sectors would do well to heed.
•Compressed natural gas vehicle exhaust solid particle emissions depend on lubricant quality.•Effect of lubricant quality is higher in < 10 nm particle size range.•Solid particle emissions focus on ...first 30 s after engine start.•Lubricant quality has an effect on compressed natural gas vehicle fuel consumption.
Lubricant oil affects the fuel consumption and exhaust emissions of passenger cars. Oil reduces the friction in combustion engines, yet simultaneously some lubricating oil is exhausted from the engine. The fugitive lubricant oil results in < 30 nm solid particle number (SPN) emissions in the exhaust gas. The characteristics and formation path of the small particles is not well known, but as the SPN regulation is extending down to 10 nm size range, they cannot be neglected. Vehicles using compressed natural gas (CNG) fuel are known to emit solid particles in the < 23 nm size range. Here we studied the emissions of a CNG-fuelled Euro 6 light-duty vehicle using different lubricants. The lubricant characteristics had a strong effect on < 23 nm SPN emissions. A high ash, high volatility lubricant was shown, to alter the SPN population also in > 10 nm and even > 23 nm size range, thus, underlining the importance of the lubricant quality. The difference between the high volatility lubricant and the two tested modern lubricants was most evident at high temperature, high speed driving, while the emissions at the start of the cycle were of the same order of magnitude for all oils. The lubricant formulation was also shown to affect the vehicle CO2 emissions. The vehicle CO2 emissions in the tests driven with the high volatility lubricant oil exceeded the emissions with optimized lubricant oil by as much as 2%. Thus, the right lubricant choice can lead to fuel savings in CNG-fuelled vehicles. The presented results demonstrate the origin of the < 23 nm SPN in CNG-fuelled vehicles.
Greek Rebetiko from a Psychocultural Perspective: Same Songs Changing Minds examines the ways in which audiences in present-day Greece and Turkey perceive and use the Greek popular song genre ...rebetiko to cultivate specific cultural habits and identities. In the past, rebetiko has been associated chiefly with the lower strata of Greek society. But Daniel Koglin approaches the subject from a different perspective, exploring the mythological and ritual aspects of rebetiko, which intellectual elites on both sides of the Aegean Sea have adapted to their own world views in our age of globalized consumption. Combining qualitative and quantitative methods from ethnomusicology, ritual studies, conceptual history and music psychology, Koglin casts light on the role played by national perceptions in the processes of music production and consumption. His analysis reveals that rebetiko persistently oscillates between conceptual categories: it is a music both ours and theirs, marginal and mainstream, joyful and grievous, sacred and profane. The study culminates in the thesis that this semantic multistability is not only a key concept to understanding the ongoing popularity of rebetiko in Greece, and its recent renaissance in Turkey, but also a fundamental aspect of the human experience on the south-eastern borders of Europe.
