An Assessment of Civic Engagement and Educational Attainment

It is well documented that individuals with higher levels of education tend to be more civically engaged. In a two-part study conducted for the Center for Information and Research on Civic Learning and Engagement (CIRCLE), we provide empirical evidence using 1988-2000 panel data from the National Education Longitudinal Study of 1988 (NELS) that civic engagement might also promote educational attainment: civically-engaged teenagers make greater scholastic progress during high school and subsequently acquire higher levels of education than their otherwise similar peers. Our first essay provides supporting empirical evidence for this relationship in general, and the second essay broadens these findings across gender and race/ethnicity. With regards to policy relevance, the primary results point to the importance of civic participation as one means to foster both social and human capital investments. The purpose of this fact sheet is to provide highlights from our two-part study

The English-Language Proficiency of Recent Immigrants in the U.S. During the Early 1900s

Using U.S. decennial census data, we find that in 1920, immigrants (particularly those from Southern and Eastern Europe) were more likely to speak the English language within three years of migrating than their counterparts had been in either 1900 or 1910. Our results suggest that the foreign-born reacted to socioeconomic and political events by learning English before or shortly after migrating to the U.S. This study not only provides previously unknown information about immigrants’ English fluency in the early twentieth century, but it also offers empirical insight into the assimilation pressures that certain immigrant groups experienced at the time.

The problem is my partner: Treating couples when one partner wants the other to change

Partners commonly present to couple therapy expecting that the relationship will only improve if their partner changes. In other words, the partner is the problem. In this paper we review research on people\u27s capacity for change, the process of behavior change, and personality change, especially the role of attachment theory. We then review techniques for working with couples based on empirically validated approaches to couple therapy and general change principles in therapy. Finally, we present a case study and recommendations for working with change-demanding couples, emphasizing the importance of focusing on emotional acceptance

Gender and Business Outcomes of Black and Hispanic New Entrepreneurs in the United States

In light of the growing numbers of women of color in the entrepreneurial sector in the United States, employing public-use microdata from the 2007 Survey of Business Owners, this study finds that new firms owned by black and Hispanic women were more likely to cease operations than those owned by their male counterparts or by non-Hispanic whites, even when controlling for other owner- and firm-level characteristics and labor market conditions. These differences occurred despite the existence of public programs designed to help female and minority entrepreneurs, raising the question of efficiency of the current policy infrastructure in the United States

Object use in communication of semi-wild chimpanzees

Catherine Hobaiter’s research work is funded under the European Union’s 8th Framework Programme under grant agreement 802719. The research of Marina Davila-Ross is funded by Leakey Foundation Research Grant and Royal Society Research Grant (RG140282).Object interactions play an important role in human communication but the extent to which nonhuman primates incorporate objects in their social interactions remains unknown. To better understand the evolution of object use, this study explored how objects are used in social interactions in semi-wild chimpanzees (Pan troglodytes). We used an observational approach focusing on naturally occurring object actions where we examined their use and tested whether the production of object actions was influenced by the recipients' visual attention as well as by colony membership. The results show that chimpanzees adjusted both the type of object used, and the modality of object actions to match the visual attention of the recipient, as well as colony differences in the use of targeted object actions. These results provide empirical evidence highlighting that chimpanzees use objects in diverse ways to communicate with conspecifics and that their use may be shaped by social factors, contributing to our understanding of the evolution of human nonverbal communication, language, and tool use.Publisher PDFPeer reviewe

Squalene Extraction: Biological Sources and Extraction Methods

Squalene is a terpenoid with great importance in cosmetic, food and pharmaceutical industry; it was originally isolated from shark liver oil but is easily found in animals, vegetables and microorganisms. Nowadaysis shark fishing is prohibited in some countries, that is the main reason to use renewable sources forsqualene extraction to protect marine life, since last decade, squalene is extracted from different sources and methods to achieve best yields at lower possible cost. Traditional extraction methods usually involve organic solvents as hexane which left residues on the extracted matrix, that can limit material use for human consumptionafter extraction. Separation and purification stages after extraction can elevate operations cost, one of the most interesting technology to obtain squalene from biological matrix is supercritical fluid extraction with CO2as solvent because of economic, safe and easy removal characteristics

Organizing the innovation process : complementarities in innovation networking

This paper contributes to the developing literature on complementarities in organizational design. We test for the existence of complementarities in the use of external networking between stages of the innovation process in a sample of UK and German manufacturing plants. Our evidence suggests some differences between the UK and Germany in terms of the optimal combination of innovation activities in which to implement external networking. Broadly, there is more evidence of complementarities in the case of Germany, with the exception of the product engineering stage. By contrast, the UK exhibits generally strong evidence of substitutability in external networking in different stages, except between the identification of new products and product design and development stages. These findings suggest that previous studies indicating strong complementarity between internal and external knowledge sources have provided only part of the picture of the strategic dilemmas facing firms

Hinode/EIS observations of propagating low-frequency slow magnetoacoustic waves in fan-like coronal loops

We report the first observation of multiple-periodic propagating disturbances along a fan-like coronal structure simultaneously detected in both intensity and Doppler shift in the Fe XII 195 A line with the EUV Imaging Spectrometer (EIS) onboard Hinode. A new application of coronal seismology is provided based on this observation. We analyzed the EIS sit-and-stare mode observation of oscillations using the running difference and wavelet techniques. Two harmonics with periods of 12 and 25 min are detected. We measured the Doppler shift amplitude of 1-2 km/s, the relative intensity amplitude of 3%-5% and the apparent propagation speed of 100-120 km/s. The amplitude relationship between intensity and Doppler shift oscillations provides convincing evidence that these propagating features are a manifestation of slow magnetoacoustic waves. Detection lengths (over which the waves are visible) of the 25 min wave are about 70-90 Mm, much longer than those of the 5 min wave previously detected by TRACE. This difference may be explained by the dependence of damping length on the wave period for thermal conduction. Based on a linear wave theory, we derive an inclination of the magnetic field to the line-of-sight about 59$\pm$8 deg, a true propagation speed of 128$\pm$25 km/s and a temperature of 0.7$\pm$0.3 MK near the loop's footpoint from our measurements.Comment: 4 pages and 4 figures, with 3 online figures and 1 online table; Astron & Astrophys Letter, in pres
