The Impact of the Falling Yen on U.S. Import Prices

[Excerpt] In the fall of 2012, Japan set forth economic policies aimed at turning around the country’s historic deflationary slide that began in the 1990s. These policies led the Japanese yen to fall dramatically in value relative to the U.S. dollar, reversing what was a long upward trend of strength against the dollar. From September 2012 to May 2013, the yen–dollar exchange rate plummeted 22.5 percent. Although the rate of decline decelerated considerably over the remainder of the year, the yen fell an additional 2.4 percent against the U.S. dollar between May and December. A falling yen means the purchasing power of the U.S. dollar increases for goods imported from Japan. Parallel to the drop in the value of the yen, import prices of Japanese goods fell 3.5 percent from September 2012 to December 2013. The drop in the value of the yen particularly influenced prices in major product areas such as nonelectrical machinery, computers and electronic products, and chemicals, which combined make up nearly 40 percent of U.S. imports from Japan. The industry that is most affected by Japanese import prices is the transportation vehicles industry, which alone represents 42 percent of U.S. imports from Japan

An appreciative inquiry into the transformative learning experiences of students in a family literacy project

Educational discourse has often struggled to genuinely move beyond deficit-based language. Even action research, a predominant model for teacher development, starts with the identification of a problem (Cardno 2003). It would appear that the vocabulary for a hope-filled discourse which captures the imagination and infiuences our future educational activity seems to have escaped us. Moreover, we seem bereft of educational contexts where the experience for students is holistic and transformative

Explanations of pedophilia: Review of empirical research

This article reviews empirical research to discover what support exists for theories that attempt to explain why adults become sexually interested in and involved with immature children. These theories are first organized into four basic categories: emotional congruence-why the adult congruence - why an emotional need to relate to a child; sexual arousl-why the adult could become sexually aroused by a child; blockage - why alternative sources of sexual and emotional gratification are not available; or disinhibition - why the adult is not deterred from such an interest by normal prohibitions. The review shows that the best experimental research has been directed toward establishing that pedophiles do not show an unusual pattern of sexual arousal toward children, although no good evidence yet exists about why this is so; a number of studies have concurred that pedophiles are blocked in their social and heterosexual relationships; the use of alcohol is well established as a disinhibiting factor that plays a role in a great many pedophile offenses; at least one study gives support to the \u27emotional congruence\u27 idea that children, because of their lack of dominance, have some special meaning for pedophiles; and there is evidence that many pedophiles were themselves victims of pedophile behavior when they were children. The article also demonstrates that pedophilia research is, in general, characterized by some serious theoretical and methodological flaws. As a result, caution should be exercised in generalizing findings until more careful research is undertaken

Passport: enabling accurate country-level router geolocation using inaccurate sources

When does Internet traffic cross international borders? This question has major geopolitical, legal and social implications and is surprisingly difficult to answer. A critical stumbling block is a dearth of tools that accurately map routers traversed by Internet traffic to the countries in which they are located. This paper presents Passport: a new approach for efficient, accurate country-level router geolocation and a system that implements it. Passport provides location predictions with limited active measurements, using machine learning to combine information from IP geolocation databases, router hostnames, whois records, and ping measurements. We show that Passport substantially outperforms existing techniques, and identify cases where paths traverse countries with implications for security, privacy, and performance.First author draf

Statistical and Clinical Aspects of Hospital Outcomes Profiling

Hospital profiling involves a comparison of a health care provider's structure, processes of care, or outcomes to a standard, often in the form of a report card. Given the ubiquity of report cards and similar consumer ratings in contemporary American culture, it is notable that these are a relatively recent phenomenon in health care. Prior to the 1986 release of Medicare hospital outcome data, little such information was publicly available. We review the historical evolution of hospital profiling with special emphasis on outcomes; present a detailed history of cardiac surgery report cards, the paradigm for modern provider profiling; discuss the potential unintended negative consequences of public report cards; and describe various statistical methodologies for quantifying the relative performance of cardiac surgery programs. Outstanding statistical issues are also described.Comment: Published in at http://dx.doi.org/10.1214/088342307000000096 the Statistical Science (http://www.imstat.org/sts/) by the Institute of Mathematical Statistics (http://www.imstat.org

Early specification of sensory neuron fate revealed by expression and function of neurogenins in the chick embryo

The generation of sensory and autonomic neurons from the neural crest requires the functions of two classes of basic helix-loop-helix (bHLH) transcription factors, the Neurogenins (NGNs) and MASH-1, respectively (Fode, C., Gradwohl, G., Morin, X., Dierich, A., LeMeur, M., Goridis, C. and Guillemot, F. (1998) Neuron 20, 483-494; Guillemot, F., Lo, L.-C., Johnson, J. E., Auerbach, A., Anderson, D. J. and Joyner, A. L. (1993) Cell 75, 463-476; Ma, Q., Chen, Z. F., Barrantes, I. B., de la Pompa, J. L. and Anderson, D. J. (1998 Neuron 20, 469-482). We have cloned two chick NGNs and found that they are expressed in a subset of neural crest cells early in their migration. Ectopic expression of the NGNs in vivo biases migrating neural crest cells to localize in the sensory ganglia, and induces the expression of sensory neuron-appropriate markers in non-sensory crest derivatives. Surprisingly, the NGNs can also induce the expression of multiple pan-neuronal and sensory-specific markers in the dermomyotome, a mesodermal derivative. Taken together, these data suggest that a subset of neural crest cells may already be specified for a sensory neuron fate early in migration, as a consequence of NGN expression

High-Stakes Testing and Student Achievement: Problems for the No Child Left Behind Act

Under the federal No Child Left Behind Act of 2001 (NCLB), standardized test scores are the indicator used to hold schools and school districts accountable for student achievement. Each state is responsible for constructing an accountability system, attaching consequences -- or stakes -- for student performance. The theory of action implied by this accountability program is that the pressure of high-stakes testing will increase student achievement. But this study finds that pressure created by high-stakes testing has had almost no important influence on student academic performance
