TL;DR: In this article, a new synthesis of pressure-temperature conditions and pressure temperature-time (P-T-t) paths is presented for high-grade metamorphic thrust sheets associated with the Main Central Thrust, in the Langtang and Darondi regions, central Nepal.
Abstract: A new synthesis of pressure-temperature conditions and pressure-temperature-time (P-T-t) paths is presented for high-grade metamorphic thrust sheets associated with the Main Central Thrust, in the Langtang and Darondi regions, central Nepal. From structurally low to structurally high, major structures include the Lesser Himalayan Duplex, Munsiari Thrust, Main Central Thrust (thrust contact between the Greater and Lesser Himalayan Sequences), and Langtang Thrust. Key P-T-t results include the following: in a transect from Lesser Himalayan Duplex to Langtang Thrust rocks, peak metamorphic P-T conditions are uniformly ∼550 °C and 8 kbar in the Lesser Himalayan Duplex, and show a strong gradient to ∼725 °C and 10–12 kbar over a structural distance of less than 2 km associated with the Munsiari Thrust and Main Central Thrust; T9s then increase and P9s decrease gradually upsection, reaching ∼825 °C and 8 kbar in the Langtang Thrust. Juxtaposition of thrust sheets occurred at moderate pressure (8–12 kbar) on thrust surfaces roughly coincident with the modern Main Himalayan Thrust. Published monazite ages demonstrate synmetamorphic thrusting, with peak metamorphic ages decreasing progressively downward: 21 ± 2 Ma (Langtang Thrust), 16 ± 1 Ma (Main Central Thrust), 10.5 ± 0.5 Ma (Munsiari Thrust), and 3.5 ± 0.5 Ma (Lesser Himalayan Duplex). Together with published thermochronologic results, these data constrain initial cooling ages and rates: 15–20 Ma and ∼40 °C/m.y. for the Langtang Thrust and Main Central Thrust, and 3–10 Ma and ≥100 °C/m.y. for the Munsiari Thrust and Lesser Himalayan Duplex. Overall, metamorphic and chronologic patterns are matched well by expectations of critical taper models, including (1) uniformly high pressures of metamorphism (8–12 kbar) for all structural levels and thrust movement along the paleo–Main Himalayan Thrust, (2) isobaric cooling from the peak of metamorphism for Greater Himalayan rocks (deep juxtaposition of thrust sheets), (3) “hairpin” P-T paths for Lesser Himalayan rocks, and (4) relatively slow cooling rates for Greater Himalayan rocks. However, observations contrast significantly with published channel flow models, which predict (1) peak P-T conditions within the sillimanite stability field for Lesser and lower Greater Himalayan rocks (versus observations of P-T conditions in the kyanite stability field), (2) peak metamorphic pressures that decrease structurally downward—7–13, 6, 5, and 5 kbar for rocks achieving temperatures recorded by Langtang Thrust, Main Central Thrust, Munsiari Thrust, and Lesser Himalayan Duplex rocks (versus observations of 8, 10–12, 10, and 8 kbar), (3) retrograde isothermal exhumation P-T trajectories for Greater Himalayan rocks (versus isobaric cooling of the Main Central Thrust and Langtang Thrust), (4) cooling of migmatitic Greater Himalayan rocks after 10 Ma (versus observations of 15–20 Ma), and (5) isobaric heating of the Lesser Himalayan rocks (versus observations of simultaneous increases in P and T for some Lesser Himalayan rocks). Neither model matches “clockwise” P-T paths observed in structurally high Lesser Himalayan rocks, or the extraordinary cooling rate of the Lesser Himalayan Duplex, which points to complications in their evolution in the context of end-member models. Most generally, although channel flow may have initiated since ca. 10 Ma due to focused erosion above the Lesser Himalayan Duplex, it does not appear responsible for past transport and exhumation of the migmatitic core of the Himalaya.

TL;DR: Neither depression nor anxiety demonstrated any longitudinal effects on either the Agency or Pathways components of hope, and no unique effect of the Pathways component of hope on depression.
Abstract: This study tested the prospective effects of hope on depression and anxiety using a longitudinal design. A sample of 522 college students completed self-report measures of hope, depression, and anxiety at three time points, with 1-month delays between administrations. Structural equation modeling was employed to test two cross-lagged panel models of the reciprocal effects of the Agency and Pathways components of hope on depression and anxiety. Results indicated statistically significant negative effects for the Agency component of hope on later depression but no unique effect of the Pathways component of hope on depression. Likewise, Agency showed a statistically significant negative effect on later anxiety, but again Pathways had no significant influence on anxiety. In both cases, neither depression nor anxiety demonstrated any longitudinal effects on either the Agency or Pathways components of hope. Implications of these findings are discussed, along with potential directions for future research.

TL;DR: In this paper, the authors created and implemented a professional development program to address K-5 teacher confidence for, attitudes toward, knowledge of, and efficacy for teaching inquiry-based STEM and found significant and consistent increases in pre-to-postinstitute assessments of teacher confidence, efficacy, and perceptions of STEM.
Abstract: Student foundational knowledge of science, technology, engineering, and mathematics (STEM) is formed in their elementary education. Paradoxically, many elementary teachers have constrained background knowledge, confidence, and efficacy for teaching STEM that may hamper student STEM learning. The association between teacher preparation to teach STEM and student achievement in STEM motivated the authors' professional development program. The authors created and implemented a professional development program to address K–5 teacher confidence for, attitudes toward, knowledge of, and efficacy for teaching inquiry-based STEM. Using data from 2 independent cohorts the authors found significant and consistent increases in pre- to postinstitute assessments of teacher confidence, efficacy, and perceptions of STEM. Further, they found increased participant attention toward linking STEM curriculum and instruction to learning standards. Implications and suggestions for future research are discussed.

TL;DR: When 17 North American expert DNA examiners were asked for their interpretation of data from an adjudicated criminal case in that jurisdiction, they produced inconsistent interpretations, suggesting that the extraneous context of the criminal case may have influenced the interpretation of the DNA evidence, thereby showing a biasing effect of contextual information in DNA mixture interpretation.

TL;DR: A series of reviews of the use of measures of honesty, integrity, conscientiousness, dependability, trustworthiness, and reliability for personnel selection can be found in this article, where the effects of the Civil Rights Act of 1991 and the Americans with Disabilities Act are considered.
Abstract: This paper is the fourth in a series of reviews of the use of measures of honesty, integrity, conscientiousness, dependability, trustworthiness, and reliability for personnel selection (see Sackett & Decker, 1979; Sackett & Harris, 1984; Sackett, Burris, & Callahan, 1989). New developments reviewed include an examination of professional and congressional inquiry into this area of testing, rapid growth of the validity data base, new insight into similarities and differences between different tests, and links to the Big Five personality dimensions. Inquiries into relationships with other constructs, including cognitive ability, moral reasoning, and social desirability are reviewed, as are applicant reactions to these tests. The effects of the Civil Rights Act of 1991 and the Americans with Disabilities Act are considered.
