1 The Relationship between SAT Scores and Retention to the Second Year: Replication with 2009 SAT Validity
No full textThe College Board formed a research consortium with four-year colleges and universities to build a national higher education database with the primary goal of validating the revised SAT) for use in college admission. A study by Mattern and Patterson (2009) examined the relationship between SAT scores and retention to the second year. The sample included first-time, first-year students entering college in fall 2006, with 106 of the original 110 participating institutions providing data on retention to the second-year. Results showed that SAT performance was related to retention, even after controlling for relevant student and institutional characteristics. Replication studies have been conducted for subsequent entering cohorts of students and similar results were found (Mattern & Patterson, 2011a, 2011b). Replicating the analyses of the previous three reports (Mattern & Patterson, 2009; 2011a, 2011b), the current study examined the relationship between SAT performance and retention to the second year for first-time, first-year students that began in the fall of 2009. A total of 131 institutions provided data which translated to 262,949 students. Students without SAT scores, self-reported high school grade point average (HSGPA), or retention data were removed from analyses, resulting in a final sample size of 199,366 students. The results from the current study based on the 2009 sample show the same pattern of results as the previous reports. Namely, higher SAT scores are associated with higher retention rates. This was true, even after controlling for student characteristics (gender, race/ethnicity, household income, parental education, and HSGPA) and institutional characteristics (control, size, and selectivity)

Thermal maturity of the Hawasina units and origin of the Batinah Mélange (Oman Mountains). Insights from clay minerals
No full textThe Oman Mountains developed during Cretaceous to Cenozoic time by obduction of the Semail Ophiolite on top of the Arabian rifted margin. The tectonic pile of the orogenic system is composed of three major domains, which from bottom to top are: (i) the proximal domain of the Arabian rifted margin; (ii) the Hawasina Nappe, including rocks pertaining to the distal portions of the Arabian rifted margin; (iii) the Upper Cretaceous Semail Ophiolite. However, in NE Oman (Batinah Coastal Plain), exposures of Hawasina rocks are resting above the ophiolite. What is the origin of the uncommon structural position of Hawasina rocks in the Batinah Coastal Plain? To address this question, an extensive dataset of X-ray diffraction analyses from rocks of the Hawasina units has been used to reconstruct their thermal and burial history since the Late Cretaceous. Temperature-dependent clay minerals indicate that the Hawasina units experienced different levels of thermal maturity from early diagenetic to anchizone conditions depending on their structural position during orogenic build-up. Rocks from the Hawasina units resting above the ophiolite contain random-ordered mixed layer illite-smectite (I–S) with an illite content between 30 and 45% displaying low levels of thermal maturity reflecting early diagenetic conditions that were acquired because of limited sedimentary burial (600 m) and minor heating during the early Pliocene. Deep-water rocks of the Hawasina units below the ophiolite are characterized by long-range ordered mixed layer I–S with an illite content between 80 and 90% and by a mineralogical assemblage of rectorite and pyrophyllite displaying more evolved levels of thermal maturity in deep diagenetic/anchizone conditions that were acquired during the obduction of the 4100 to 5500 m thick Semail Ophiolite. We finally propose a new evolutionary scheme for the genesis of the Batinah Mélange, that was not buried by the ophiolite but was transported by gravity-driven mass transport on top of the ophiolite. Our results may further improve the assessment of thermal maturity of Arabian passive margin deposits for hydrocarbon exploration purposes

Imaging with seismic noise: improving extraction of body wave phases from the deep Earth through selective stacking based on H/V ratios
No full textGenerating high-resolution images of the deep Earth remains a challenge. Body waves extracted from noise correlations hold high promise to complement earthquake-based studies, but data processing and interpretation are still under development. We develop a methodology to improve signal-to-noise ratio (SNR) of P410P and P660P, waves reflected at the top and bottom of the mantle transition zone, using data from the greater Alpine area and focussing on the second microseismic peak (2.5-10 s period). Rather than stacking all available data, we only stack correlations for days with a low ratio of amplitudes between the horizontal plane and vertical direction (H/V). Due to an improved SNR we can stack over fewer correlation pairs, with the result that horizontal resolution is significantly improved. We propose a systematic approach to determine at each study point the optimal combination of station pairs and the H/V threshold. We observe that the optimal choice of parameters is location dependent and that it is generally different for P410P and P660P. Additionally, we show that in our study area the maximum interstation distance needs to be reduced to ∼150 km for P410P to avoid that this arrival is contaminated by surface waves. Applied to the greater Alpine area we demonstrate a significant improvement of signal extraction: while P410P and P660P were only sporadically identified in standard stacks, with the new processing scheme these arrivals are clearly identified with coherent phases across large distances. We also show that amplitudes of P660P decrease drastically around longitude ∼11°E to ∼12°E, indicating that the lower discontinuity of the transition zone in that area is too broad to have a significant reflexion coefficient for P waves in the second microseismic peak
Crystal structure determination of an addition complex of N-isopropyl-salicylaldimine with zinc iodide and of bis(N-isopropyl-salicylaldiminato) zinc chelate
No full textThe crystal structures of bis(N-isopropyl)-salicylaldiminato zinc iodide [I2Zn(C20H24N2O2)] (adduct 1) and of bis-chelate-N-isopropyl-salicylaldiminato zinc (complex 2) Zn (C20H24N2O2) have been determined at room temperature by X-ray diffraction methods. Adduct 1 crystallizes in space group P21/c with a = 9.229(2), b = 10.610(2), c = 24.711(4)Å, α = Υ = 90°, β = 94.04°, V = 2413.68 Å3, with Z = 4 units. The structure confirms the adduct nature of the compound; it shows an asymmetry with respect to the I —Zn —I plane and some additional disorder in one of the two N-isopropyl groups. Bis-chelate 2 crystallizes in orthorhombic form, space group Pbca,with a = 13.225(2), b = 19.476(2), c = 15.155(4) Å,V =3903.47 Å3,with Z = 8 units. The structure consists of monomeric units in which the zinc atom shows slightly distorted tetrahedral geometry. The structures have been solved by direct methods and refined by least- squares calculations to a final R value of 0.0296 for 3146 unique observed reflections [I≥ 3σ(I)] for adduct 1, and to an R value of 0.0339 for 2376 unique observed reflections for bis-chelate 2. © by R.

Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
