Melancholic Satires argues that eighteenth-century satires invite readers to become more aware that their bodies always unsettle their minds. Scholars traditionally define satire as a normative mode of criticism that uses wit and humour to denounce deviations from moral standards. These scholars have not yet considered that these texts mobilize anti-normative practices of resisting structures of domination through bodily and passionate criticism. My project introduces the affects of passion and the body as valid objects of inquiry in the field of satire studies. Authors such as Jane Collier, Anne Finch, Alexander Pope, Tobias Smollett, and Jonathan Swift develop what I call “melancholic satires,” ones that not only present a figure with a melancholic perspective, but also convey passionate rhetoric that evokes the disruptive body’s influence on the mind. Medical theorists pathologize that the body’s humours and passions destabilize the mind into the delusional state known as melancholy, and moral philosophers recommend the moderation of the disruptive passions as virtuous conduct. These skeptical accounts understand that the passions represent unstable sense-impressions, and they suspiciously believe that the passions can disrupt rational thinking. Instead, eighteenth-century satires advocate that melancholic destabilization can beneficially inspire the mind into subversive critique. For instance, in Smollett’s Humphry Clinker, Matthew Bramble’s sickly feelings influence him into criticizing that London’s commercialism represents a diseased condition. Bramble’s sensitivity to his diseased body enables his satirical sensitivity to commercial excess. Moreover, in Finch’s poem The Spleen, her speaker articulates a sensitivity to her melancholic spleen in order to critically reject misogynistic views that limit women’s occupations to the domestic sphere. My project proposes that understanding eighteenth-century satires requires the analysis of how these texts’ affective and corporeal rhetoric persuades audiences of the perverse virtues of embodied sensitivity. Melancholic Satires contends that satirical literature champions the emotional foundations of social commentary.

International audience; We have investigated several particles collected during each of two touchdowns of the Hayabusa2 spacecraft at the surface of the C-type asteroid 162173 Ryugu using various electron microscope techniques. Our detailed transmission electron microscopy study shows the presence of magnetite with various morphologies coexisting in close proximity. This is characteristic of CI chondrite-like materials and consistent with the mineral assemblages and compositions in the Ryugu parent body. We describe the microstructural characteristics of magnetite with different morphologies, which could have resulted from the chemical conditions (growth vs. diffusion rate) during their formation. Furthermore, we describe the presence of magnetites with a spherulitic structure composed of individual radiating fibers that are characterized by pervasive, homogeneously distributed euhedral to subhedral pores that have not been described in previous chondrite studies. This particular spherulitic structure is consistent with crystallization under nonequilibrium conditions. Additionally, the presence of a high density of defects within the magnetite fibers, the high surface/volume ratio of this morphology, and the presence of amorphous materials in several pores and at the edges of the acicular fibers further support their formation under nonequilibrium conditions. We suggest that the growth processes that lead to this structure result from the solution reaching a supersaturated state, resulting in an adjustment to a lower free energy condition via nucleation and rapid growth.

Volatile components are abundant in carbonaceous asteroids and can be important tracers for the evolution of asteroid surfaces interacting with the space environment, but their behavior on airless surfaces is poorly understood. Samples from the C-type carbonaceous asteroid Ryugu show dehydration of phyllosilicate, indicating ongoing surface modifications on the aqueously-altered asteroid. Here we report the analysis of Ryugu samples showing selective liberation of carbon, oxygen, and sulfur from iron-rich oxide, sulfide, and carbonate, which are major products of aqueous alteration. These mineral surfaces are decomposed to metallic iron, iron nitride, and magnesium-iron oxide. The modifications are most likely caused by solar wind implantation and micrometeorite impacts and are distinct indicators of surface space exposure over 103 years. Nitridation of metallic iron may require micrometeorites rich in solid nitrogen compounds, which implies that the amount of nitrogen available for planetary formation in the inner solar system is larger than previously recognized.

Without a protective atmosphere, space-exposed surfaces of airless Solar System bodies gradually experience an alteration in composition, structure and optical properties through a collective process called space weathering. The return of samples from near-Earth asteroid (162173) Ryugu by Hayabusa2 provides the first opportunity for laboratory study of space-weathering signatures on the most abundant type of inner solar system body: a C-type asteroid, composed of materials largely unchanged since the formation of the Solar System. Weathered Ryugu grains show areas of surface amorphization and partial melting of phyllosilicates, in which reduction from Fe3+ to Fe2+ and dehydration developed. Space weathering probably contributed to dehydration by dehydroxylation of Ryugu surface phyllosilicates that had already lost interlayer water molecules and to weakening of the 2.7 µm hydroxyl (–OH) band in reflectance spectra. For C-type asteroids in general, this indicates that a weak 2.7 µm band can signify space-weathering-induced surface dehydration, rather than bulk volatile loss.

The Almahata Sitta (AhS) meteorite is a unique polymict ureilite. Recently, carbonaceous chondritic lithologies were identified in AhS. Organic matter (OM) is ubiquitously found in primitive carbonaceous chondrites. The molecular and isotopic characteristics of this OM reflect its origin and parent body processes, and are particularly sensitive to heating. The C1 lithologies AhS 671 and AhS 91A were investigated, focusing mainly on the OM. We found that the OM in these lithologies is unique and contains primitive isotopic signatures, but experienced slight heating possibly by short-term heating event(s). These characteristics support the idea that one or more carbonaceous chondritic bodies were incorporated into the ureilitic parent body. The uniqueness of the OM in the AhS samples implies that there were large variations in primitive carbonaceous chondritic materials in the solar system other than known primitive carbonaceous chondrite groups such as CI, CM, and CR chondrites.

We present in this study the effects of short-term heating on organics in the Tagish Lake meteorite and how the difference in the heating conditions can modify the organic matter (OM) in a way that complicates the interpretation of a parent body’s heating extent with common cosmothermometers. The kinetics of short-term heating and its influence on the organic structure are not well understood, and any study of OM is further complicated by the complex alteration processes of the thermally metamorphosed carbonaceous chondrites—potential analogues of the target asteroid Ryugu of the Hayabusa2 mission—which had experienced posthydration, short-duration local heating. In an attempt to understand the effects of short-term heating on chondritic OM, we investigated the change in the OM contents of the experimentally heated Tagish Lake meteorite samples using Raman spectroscopy, scanning transmission X-ray microscopy utilizing X-ray absorption near edge structure spectroscopy, and ultraperformance liquid chromatography fluorescence detection and quadrupole time of flight hybrid mass spectrometry. Our experiment suggests that graphitization of OM did not take place despite the samples being heated to 900 °C for 96 h, as the OM maturity trend was influenced by the heating conditions, kinetics, and the nature of the OM precursor, such as the presence of abundant oxygenated moieties. Although both the intensity of the 1s σ* exciton cannot be used to accurately interpret the peak metamorphic temperature of the experimentally heated Tagish Lake sample, the Raman graphite band widths of the heated products significantly differ from that of chondritic OM modified by long-term internal heating.

Multicultural mentoring has been suggested to support Latin@ faculty success in their careers, yet current literature on effective mentorships of Latin@ faculty is limited. This critical co-constructed autoethnography draws on critical race theory (CRT) and latin@ critical race theory (LatCrit) frameworks to highlight the lived experiences and key elements of an effective gendered cross-cultural mentoring relationship in a Latin@ pretenure faculty dyad working in a predominantly White institution of higher education located in the Deep South of the United States. Drawing upon a methodological rhythm of sorts, a Black scholar acts as a muse providing testimonios and interpretations of a relationship existing among Latin@ scholars in predominantly White intellectual spaces. Findings from this critical co-constructed autoethnography note that a safe colored space supports effective mentoring, familismo, personalismo, enabling effective cross-cultural mentorship.

Life on Earth shows preference toward the set of organics with particular spatial configurations. Enantiomeric excesses have been observed for α-methyl amino acids in meteorites, which suggests that chiral asymmetry might have an abiotic origin. A possible abiotic mechanism that could produce chiral asymmetry in meteoritic amino acids is their formation under the influence of asymmetric catalysts, as mineral crystallization can produce spatially asymmetric structures. Although magnetite plaquettes have been proposed to be a possible candidate for an asymmetric catalyst, based on the suggestion that they have a spiral structure, a comprehensive description of their morphology and interpretation of the mechanism associated with symmetry-breaking in biomolecules remain elusive. Here we report observations of magnetite plaquettes in carbonaceous chondrites (CC) that were made with scanning electron microscopy and synchrotron X-ray computed microtomography (SXRCT). We obtained the crystal orientation of the plaquettes using electron backscatter diffraction (EBSD) analysis. SXRCT permits visualization of the internal features of the plaquettes. It provides an unambiguous conclusion that the plaquettes are devoid of a spiral feature and, rather that they are stacks of individual magnetite disks that do not join to form a continuous spiral. Despite the lack of spiral features, our EBSD data show significant changes in crystal orientation between adjacent magnetite disks. The magnetite disks are displaced in a consistent relative direction that lead to an overall crystallographic rotational mechanism. This work offers an explicit understanding of the structures of magnetite plaquettes in CC, which provides a fundamental basis for future interpretation of the proposed symmetry-breaking mechanism.

A simple direct method for the rapid fabrication of zinc oxide nanotube-nanowire hybrid structure in an environmentally friendly way is described here. Zinc foils were anodized in an aqueous solution of washing soda and baking soda at room temperature in order to obtain the hybrid architecture. At the beginning of the process nanowires were formed on the substrate. The wider nanowires transformed into nanotubes in about a minute and grew in length with time. The morphological integrity was maintained upon heat treatment at temperatures up to the melting point of the substrate (∼400 °C) except that the nanotube wall became porous. The chemiresistor devices fabricated using the heat-treated structure exhibited high response to low-concentration volatile organic compounds that are considered markers for breast cancer. The response was not significantly affected by high humidity or presence of hydrogen, methane, or carbon dioxide. The devices are expected to find use as breath sensors for noninvasive early detection of breast cancer.

Cement job design has historically been a static process largely independent of the other processes in the drilling and completion phases. The success or failure of achieving zonal isolation, which is the main objective of cementing, is usually attributed to the cement placement result without analyzing in details various factors such as drilling parameters, borehole shape, drilling fluid properties, casing designs, formation properties (temperature and pressure profiles), and even cement evaluation methods including post-cement placement activities that could contribute to the end result of achieving zonal isolation objectives for long-term well integrity on an oil and gas well. A unique workflow is developed by incorporating data from different stages of the well construction process (drilling, cementing and cement evaluation) to optimize the cement job design and placement evaluation for critical and challenging wells. By integrating real-time or near real-time data from drilling and cementing phases, the unique workflow rapidly identifies critical information that can prevent poor cement placement, which allows operators to make timely decision to achieve well integrity and safe working environment. An integration of drilling and openhole information, cement slurry design and placement/mud removal result, and cement evaluation log evaluation is required to better understand zonal isolation and well integrity, particularly for wells with shallow hazards. This case study explains an integrated workflow implemented during cement placement design and evaluation on surface casing cementing job after failure of a conventional cement barrier placement in the Eagle Ford field in south Texas.

The ISS (International Space Station) currently lacks the capability to image and chemically analyze nano-to-micron scale particles from numerous engineering systems. To identify these particles, we must wait for a re-entry vehicle to return them from low earth orbit for ground-based SEM (Scanning Electron Microscope) / EDS (Energy Dispersive X-Ray Spectroscopy) analysis. This may take months, potentially delaying the affected system. Having an EDS-equipped SEM (Mochii S) aboard the ISS will accelerate response time thereby enhancing crew and vehicle safety by rapid and accurate identification of microscopic threats, especially in time-critical situations.The Mochii S payload will be stationed in the Japanese Experiment Module (JEM) powered by 120 VAC (Volts Alternating Current) inverter and connected to station Ethernet and WiFi (Fig. 1). To date the Mochii S payload has undergone testing for command and data handling, power quality, flight vibration, and radiation testing at Johnson Space Center (JSC). Mochii's high-RPM (Revolutions Per Minute) rotating vacuum pumps and high voltage systems have been reviewed to meet safety standards by JSC (Johnson Space Center) Engineering. Topology of the system in the JEM module has been baselined by ISS Safety and JAXA (Japan Space Exploration Agency). Digital controls to and from ISS over Joint Station LAN (Local Area Network) uplink have been simulated and the latencies and data rates have been found to be sufficient for successful operation of the payload from ground.Transporting sensitive electron optical instruments aboard a rocket that sustains 7G acceleration for 8 minutes and then operating it the unique microgravity (micro-g) environment is no trivial matter. To meet strict safety requirements and increase robustness for mission success, over 500 unique verifications must be completed before the payload is certified for spaceflight. Two of which will be discussed in detail are: vibroacoustic testing and magnetic susceptibility shielding and validation.

The purpose of this study was to examine the effects of story mapping on the reading comprehension scores, on-task behaviors, and attitudes of third- -grade students (N = 6) with ADHD. Students’ reading grade equivalencies were assessed before and after the study. The teacher-researcher compared two other achievement measures before and during story mapping to assess growth. The practical difference in scores as calculated with Cohen’s d revealed that story mapping was successful in improving students’ comprehension. On tests from the reading basal, students’ scores improved an average of 16.00%, while tests from a computerized reading program improved 20.00%. Students exhibited on-task behavior 79.33% of the time and positive attitudes 82.33% of the time during the intervention. The implications of this study are important in determining effective instructional strategies to promote the active engagement of students and combat the core symptoms of ADHD.

Grounded in the theoretical frameworks of constructivism and social cognitive theory, this study examined utilising culturally responsive pedagogy through a Latino themed reading task with the intention of increasing reading achievement and reading self-efficacy beliefs for culturally and linguistically diverse students. The research was conducted in an urban middle school in the south-western United States with 43 seventh grade students whose age ranged from 12 to 13 years. The majority of participants in this study reported to be Hispanic or multiracial with Hispanic origins. This study’s findings added to the existing knowledge base regarding the effectiveness of culturally responsive teaching practices. More specifically, culturally responsive pedagogy was utilised in the form of a reading task to examine its influence on students’ recall and reading comprehension performance. Furthermore, the findings of this study suggest that a culturally familiar reading task may increase reading self-efficacy bel...

In this paper, the authors deconstruct commonly held mythologies about immigration to inform the critical discourse and support those educators who strive to be fair brokers of an inclusive educational system addressing the distinct needs of immigrant students. We (teacher educators and a community organizer) emphasize and clarify verifiable information that in fact refutes seven prevalent mythologies often articulated in the public debate. In our observations and experiences, this misinformation impacts decisions and fosters biases about Latina/o immigrants in the educational field, particularly impacting students from Mexico and Latin American countries. By debunking misinformation, we seek to inform a thoughtful discourse as advocates engaged to positively influence how these students are viewed by educators. This paper highlights evidence needed to advance the learning and educational success of Latina/o students. The hope of the authors is for a more thoughtful recognition of the immigrant student plight in the face of a nationally politicized and criminalized immigration stance.

The purpose of this research study was to determine if the Edmark Reading Program increased reading fluency, attitudes, and engagement in third-grade students with disabilities (N = 7). Student fluency was measured using estimated oral reading fluency determined by the STAR reading assessment. A statistically significant difference was found between the mean gains and losses of the control group (M = -9.5) and the intervention group (M = 4.25). Student attitudes and engagement were reported using fieldnotes collected by the teacher-researcher. Percentages of student attitudes and engagement were calculated, and the results revealed that students in the treatment group were more engaged and had more positive attitudes than students in the control group.

Roll-to-roll processing of single-crystalline semiconductor thin films on low-cost flexible substrates is of high importance for flexible electronics and photovoltaic applications. In this paper we demonstrate roll-to-roll (R2R) heteroepitaxial deposition of single-crystalline-like Ge thin film on flexible cube-textured Ni–W metal substrates using an intermediate buffer layer of CeO2. Strongly biaxially-textured Ge thin film with large grain sizes in the range of 30–60 μm was obtained. The Ge film exhibited (004) out-of-plane orientation and (111) in-plane orientation spread of 6.6°. Transmission Electron Microscopy (TEM) diffraction patterns and Electron Backscattered Diffraction (EBSD) mapping confirmed the single-crystalline-like nature and highly-oriented grain structure with low angle grain boundaries. Raman measurement showed the presence of only crystalline Ge phase with TO peak width of 4.3 cm−1, close to that of single-crystal Ge wafer (3.8 cm−1), confirming the high crystalline quality of the film. The Ge film was p-type and exhibited high carrier mobility of ∼690 cm2 V−1 s−1. This alternative inexpensive, flexible and lightweight single-crystalline Ge thin film template, functionally nearly equivalent to single crystal Ge, may be a potential candidate for cost-effective R2R manufacturing of optoelectronic devices.

This action research study evaluated the effects of literacy strategies on academic achievement, motivation, and engagement of eighth-grade social studies students. Incorporating literacy strategies included teaching students to construct meaning, think critically, and build content knowledge, while stimulating their interests, using multiple texts and technology, and providing collaborative opportunities and high engagement during instructional activities. Students were divided into a literacy group and a direct instruction group with each class being taught the same content. Literacy strategies were incorporated in one class, and direct instruction activities were used in the other class. Results were determined using pre and posttest scores, a student motivation questionnaire, and a student engagement checklist. Results indicated significantly higher student achievement and engagement when literacy strategies were a part of the social studies instruction. Motivation also increased when literacy strategies were used. Literacy instruction was a beneficial strategy to improve student achievement, motivation, and engagement.

– We performed a battery of analyses on 17 samples of the Almahata Sitta meteorite, identifying three main lithologies and several minor ones present as clasts. The main lithologies are (1) a pyroxene-dominated, very porous, highly reduced lithology, (2) a pyroxene-dominated compact lithology, and (3) an olivine-dominated compact lithology. Although it seems possible that all three lithologies grade smoothly into each other at the kg-scale, at the g-scale this is not apparent. The meteorite is a polymict ureilite, with some intriguing features including exceptionally variable porosity and pyroxene composition. Although augite is locally present in Almahata Sitta, it is a minor phase in most (but not all) samples we have observed. Low-calcium pyroxene (

The current Georgia study examines middle-school-aged gang and non-gang members regarding the risk factors of gang membership and potential effects of these risk factors on academic achievement. Participants, 406 eighth grade students from a suburban middle-school, completed a 42-item survey assessing an array of demographic and risk factor variables. In addition, students provided self-report information regarding their success on national standardized testing used to measure academics readiness. Of the 28 variables analyzed, lower academic readiness was associated with ethnicity and/or gang membership. Findings are discussed in light of the complexity of the gang issue and the importance of recognizing the specificity associated with demographic predictors. Researchers are encouraged to continue exploring gang involvement in a variety of settings investigating differences in locality, school structure, and race/ethnicity. Teachers, parents, school administrators, and other key stakeholders may examine the aforementioned differences to collaboratively develop and share prevention and intervention successes and failures to enhance academic readiness and reduce gang involvement among youth.

International audience; Based upon our characterization of three separate stones by electron and X-raybeam analyses, computed X-ray microtomography, Raman microspectrometry, and visible-IR spectrometry, Sutter’s Mill is a unique regolith breccia consisting mainly of various CMlithologies. Most samples resemble existing available CM2 chondrites, consisting ofchondrules and calcium-aluminum-rich inclusion (CAI) set within phyllosilicate-dominatedmatrix (mainly serpentine), pyrrhotite, pentlandite, tochilinite, and variable amounts of Ca-Mg-Fe carbonates. Some lithologies have witnessed sufficient thermal metamorphism totransform phyllosilicates into fine-grained olivine, tochilinite into troilite, and destroycarbonates. One finely comminuted lithology contains xenolithic materials (enstatite, Fe-Crphosphides) suggesting impact of a reduced asteroid (E or M class) onto the main Sutter’sMill parent asteroid, which was probably a C class asteroid. One can use Sutter’s Mill tohelp predict what will be found on the surfaces of C class asteroids such as Ceres and thetarget asteroids of the OSIRIS-REx and Hayabusa 2 sample return missions (which willvisit predominantly primitive asteroids). C class asteroid regolith may well contain a mixtureof hydrated and thermally dehydrated indigenous materials as well as a significantadmixture of exogenous material would be essential to the successful interpretation ofmineralogical and bulk compositional data.

Ninety traditional-aged Caucasian college students (44 men and 46 women) were assigned to be group leaders according to either ambiguous or gender-based criteria. They were then presented with two dilemmas that had been prerated as masculine or feminine by a separate sample (N 87) and were asked to judge their willingness to pursue a risky decision. Women made more cautious decisions following a leadership assignment based on gender than they did on an assignment based on ambiguous criteria. However, this occurred only when the task was gender typed as masculine. A gender-based assignment had no effect on risk taking by women attempting a task gender typed as feminine. Although men were more cautious at feminine tasks than at masculine tasks, the type of assignment criterion did not alter their risk-taking judgment.

More than a metric ton of water is transported to the International Space Station (ISS) each year to provide breathing oxygen for the astronauts. Water is a safe and compact form of stored oxygen. The water is electrolyzed on ISS and ambient pressure oxygen is delivered to the cabin. A much smaller amount of oxygen is used each year in spacesuits to conduct Extra Vehicular Activities (EVAs). Space suits need high pressure (>1000 psia) high purity oxygen (must meet Aviator Breathing Oxygen "ABO" specifications, >99.5% O2). The water / water electrolysis system cannot directly provide high pressure, high purity oxygen, so oxygen for EVAs is transported to ISS in high pressure gas tanks. The tanks are relatively large and heavy, and the majority of the system launch weight is for the tanks and not the oxygen. Extracting high purity oxygen from cabin air and mechanically compressing the oxygen might enable on-board production of EVA grade oxygen using the existing water / water electrolysis system. This capability might also benefit human spaceflight missions, where oxygen for EVAs could be stored in the form of water, and converted into high pressure oxygen on-demand. Cerium oxide solid electrolyte-based ion transport membranes have been shown to separate oxygen from air, and a supported monolithic wafer form of the CeO2 electrolyte membrane has been shown to deliver oxygen at pressures greater than 300 psia. These supported monolithic wafers can withstand high pressure differentials even though the membrane is very thin, because the ion transport membrane is supported on both sides (Fig 1). The monolithic supported wafers have six distinct layers, each with matched coefficients of thermal expansion. The wafers are assembled into a cell stack which allows easy air flow across the wafers, uniform current distribution, and uniform current density (Fig 2). The oxygen separation is reported to be "infinitely selective" to oxygen [1] with reported purity of 99.99% [2]. Combined with a mechanical compressor, a Solid Electrolyte Oxygen Separator (SEOS) should be capable of producing ABO grade oxygen at pressures >2400 psia, on the space station. Feasibility tests using a SEOS integrated with a mechanical compressor identified an unexpected contaminant in the oxygen: water vapour was found in the oxygen product, sometimes at concentrations higher than 40 ppm (the ABO limit for water vapour is 7 ppm). If solid electrolyte membranes are really "infinitely selective" to oxygen as they are reported to be, where did the water come from? If water is getting into the oxygen, what other contaminants might get into the oxygen? Microscopic analyses of wafers, welds, and oxygen delivery tubes were performed in an attempt to find the source of the water vapour contamination. Hot and cold pressure decay tests were performed. Measurements of water vapour as a function of O2 delivery rate, O2 delivery pressure, and process air humidity levels were the most instructive in finding the source of water contamination (Fig 3). Water contamination was directly affected by oxygen delivery rate (doubling the oxygen production rate cut the water level in half). Water was affected by process air humidity levels and delivery pressure in a way that indicates the water was diffusing into the oxygen delivery system.

In this paper, we report results of a survey of graduate students who worked in teams on software projects. The survey revealed that there is a statistically significant gap between how team members perceived their own contribution towards the goals of the project, and how that contribution was perceived by their teammates. The paper discusses this gap and its implication for the functioning of the teams.

Norepinephrine (NE) is a major monoamine neurotransmitter that has widespread effects across multiple brain areas to regulate arousal and stress responses. The underlying function of the NE cortical system is to balance vigilance/scanning behavior with focused attention on novel environmental stimuli and the state of arousal. The central NE system is involved intrinsically with the stress response system, and dysregulation within the NE system has been implicated in the pathogenesis of anxiety and depressive disorders. Central NE activity paradoxically has either anxiogenic or anxiolytic effects, depending on whether the time course of the stress is acute or chronic, whether the stress is predictable or unpredictable, and which underlying brain regions are affected. Under conditions of chronic stress, NE system activity dysregulation of the hypothalamic-pituitary-adrenal system may turn a homeostatic stress response into a pathological stress response. Data suggest that the NE interplay with the serotonin system may exert neurobiological normalization of the pathophysiological state of anxious depression. Accordingly, pharmacological interventions targeting the NE system can result in anxiolytic, rather than anxiogenic, outcomes when used to treat patients with anxiety and depression.

The Evaluating Methods for Motivational Enhancement Education trial evaluated methods for learning motivational interviewing (MI). Licensed substance abuse professionals (N = 140) were randomized to 5 training conditions: (a) clinical workshop only; (b) workshop plus practice feedback; (c) workshop plus individual coaching sessions; (d) workshop, feedback, and coaching; or (e) a waiting list control group of self-guided training. Audiotaped practice samples were analyzed at baseline, posttraining, and 4, 8, and 12 months later. Relative to controls, the 4 trained groups showed larger gains in proficiency. Coaching and/or feedback also increased posttraining proficiency. After delayed training, the waiting list group showed modest gains in proficiency. Posttraining proficiency was generally well maintained throughout follow-up. Clinician self-reports of MI skillfulness were unrelated to proficiency levels in observed practice.

The present study investigated whether infusion of brain-derived neurotrophic factor (BDNF) could ameliorate stress-induced impairments in spatial learning and memory as well as hippocampal long-term potentiation (LTP) of rats. Chronic immobilization stress (2 h/day x 7 days) significantly impaired spatial performance in the Morris water maze, elevated plasma corticosterone, and attenuated LTP in hippocampal slices from these animals as compared with normal control subjects. BDNF was infused into the left hippocampus (0.5 mul/h) for 14 days, beginning 7 days before the stress exposure. The BDNF group was protected from the deleterious effects of stress and performed at a level indistinguishable from normal control animals despite the presence of elevated corticosterone. BDNF alone and sham infusions had no effect on performance or LTP. These results demonstrate that spatial learning and memory, and LTP, a candidate neural substrate of learning and memory, are compromised during chronic stress, and may be protected by BDNF administration.

Several methods are currently being used to predict and reject lithium-ion cells for soft or subtle shorts. Some of the methods include self-discharge tests at full SOC, self-discharge tests at 0% SOC, self-discharge tests at very low SOC, etc. An elaborate test program was carried out to compare these tests and determine if these are a true reflection of contaminants or other defects inside a lithium-ion cell. Cycle life testing of cells that failed the criteria established as well as destructive physical analysis with SEM and EDS analysis were also carried out on the samples tested under these different self-discharge tests protocols. In addition, traditional tests carried out at NASA-JSC to stringently screen cells for defects and internal shorts will also be discussed. This paper will address the topic of whether there are good methods to detect internal cell defects in li-ion cells.
