Abstract LEARNING OUTCOME: Decreased nutrition screening time by the dietitian through use of nursing assessment with automatic nutrition referral to identify patients at nutrition risk Currently the dietitian screens patient charts or interviews the patient to obtain information found on the nursing assessment form. This may take up to four hours a day. The nursing assessment form has been set up with triggers to identify patients potentially at nutrition risk. Nursing staff origin ally were trained to enter a nutrition consult in the computer when patients gave responses that had automatic triggers. The triggers were for weight change, poor intake and difficulty chewing. This information when obtained via consult along with diagnosis, weight, diet order and albumin would allow the dietitian to screen and risk the patient without accessing the chart. A performance indicator was developed to determine nursing completion of the nutrition section and referral to nutrition services. Findings: ♦ In 98% of the charts reviewed the nutrition section was completed but a consult to nutrition services was not generated. ♦ Without this information we would miss 21% of patients at high nutrition risk. ♦ The dietitian is duplicating efforts of nursing staff. ♦ Patients are asked the same questions twice. ♦ The dietitian tune not always well utilized. Results: When issue was presented to nursing, the consensus was that the form was not user friendly. A committee was appointed to investigate, redesign the form, and provide the necessary in servicing
General role of GDP dissociation inhibitor 2 in membrane release of Rab proteins: modulations of its functional interactions by in vitro and in vivo structural modifications.

The GDP dissociation inhibitors (GDIs) represent an important class of regulatory proteins in the functional cycle and recycling of Rab GTPases. Previous studies have demonstrated that GDI-1 can op...
An ultrastructural and cytological study of preimplantation development of the mouse.

Each stage of preimplantation development in the mouse from the fertilized egg to the blastocyst stage (including the unfertilized egg) was studied cytologically and ultrastructurally. Observations were made on the appearance and elaboration of several cellular organelles, inclusions and cell surface specilizations. The fertilized egg exhibits many intranuclear annulate lamellae, an increase in cytoplasmic vesicle number when compared to the unfertilized egg, and small amounts of crystalloids; mitochondria are vacuolated and small. The 2-cell stage is very similar to the fertilized egg but shows an increase in the number of cytoplasmic vesicles. The 4-cell stage is characterized by many changes: functional nucleoli appear, vacuolated mitochondria enlarge, cytoplasmic vesicles continue to increase in number, rough endoplasmic reticulum appears (as mitochondria-associated sacs), and some ribosomes are localized near the plasma membrane. At the 8-cell stage, large numbers of free ribosomes are observed in the cytoplasm, but clusters (polysomes) predominate at the 16-cell stage (morula). Morulae develop junctional complexes and exhibit differences in cytoplasmic basophilia between cells, which may be a prelude to differentiation. At the blastocyst stage, nucleoli change to an elongate form and differences in cytoplasmic background density can be observed ultrastructurally. Observations suggest that the contents of the blastocoel may be derived from the cytoplasmic vesicles, which increase in number and size subsequent to fertilization and discharge their contents into the intercellular spaces; the blastocoel arises as these fluid-filled spaces become confluent and enlarge.
Impact of Coping Efficacy and Acculturation on Psychopathology in Adolescents Following a Wildfire

There has been a considerable amount of research demonstrating links between disasters and negative life events, PTSD symptoms, and psychological distress in youth. Sociodemographic variables, such as race and gender, influence the expression of trauma and anxiety following disaster events. The current study sought to explore relationships among coping efficacy, acculturation, exposure, and psychological symptoms in African American and Caucasian adolescents who experienced wildfires. Data was collected from 206 adolescents, between 14 and 16 years of age, 3 and 10-months following the wildfires. For both groups, exposure and coping efficacy predicted trauma symptoms at 3-months post-wildfires. Furthermore, coping efficacy moderated the relationship between acculturation and trauma for African American adolescents. Exposure and coping efficacy continued to predict trauma symptoms at 10-months post wildfires for the Caucasians; whereas, exposure and acculturation were significant predictors of trauma for the African American adolescents. Overall results suggest that coping efficacy and acculturation are significant factors for African American adolescents, whereas acculturation is not a significant factor for Caucasian adolescents. Further research on intra-group variation is necessary in order to determine the impact of acculturation and other cultural factors that may affect post-disaster functioning in African American adolescents.
The effects of hydrostatic pressure on hot-electron phenomena in n-InSb

The effect of hydrostatic pressure on the Gunn effect (high pressures) and bulk avalanche breakdown (low pressures) in n-InSb is studied. The measured generation rates of electron-hole pairs at 77°K and 195°K at several pressures are compared with the theory of Dumke.
Modeling of Vapor Compression Cycles for Multivariable Feedback Control of HVAC Systems

This paper presents a new lumped-parameter model for describing the dynamics of vapor compression cycles. In particular, the dynamics associated with the two heat exchangers, i.e., the evaporator and the condenser, are modeled based on a moving-interface approach by which the position of the two-phase/single-phase interface inside the one-dimensional heat exchanger can be properly predicted. This interface information has never been included in previous lumped-parameter models developed for control design purpose, although it is essential in predicting the refrigerant superheat or subcool value. This model relates critical performance outputs, such as evaporating pressure, condensing pressure, and the refrigerant superheat, to actuating inputs including compressor speed, fan speed, and expansion valve opening. The dominating dynamic characteristics of the cycle around an operating point is studied based on the linearized model. From the resultant transfer function matrix, an interaction measure based on the Relative Gain Array reveals strong cross-couplings between various input-output pairs, and therefore indicates the inadequacy of independent SISO control techniques. In view of regulating multiple performance outputs in modern heat pumps and air-conditioning systems, this model is highly useful for design of multivariable feedback control.
LCEC Detector with Graphite-Teflon Electode

Abstract A compression molded graphite-Teflon electrode is evaluated as a detector for the electrochemical detection of phenolic compounds, separated by reverse-phase high-performance liquid chromatography. Detection limits for these phenolic compounds range from 0.5–1 ng. Repetitive injections yield peak heights with RSDs less than 1%. Passivation of electrode surface by phenols is discussed. In addition, construction of a flow cell to be used in conjunction with graphite-Teflon electrode is also described.
Dual-Language Education for English Language Learners

0 Dual-language education (DLE) provides instruction aimed at developing bilingual abilities. Contexts and languages vary widely, from Spanish/English programs in the United States, to a Hungarian/Slovak school in the Slovak Republic, to a Maori/English program in New Zealand (Christian & Genesee, 2001). These schools share a common goal: development of the Li of the students along with high levels of proficiency and literacy in an L2. An increasingly popular form of DLE is two-way immersion, in which students from two different language backgrounds are integrated for all or most of the instructional day. All students receive content instruction and literacy instruction in both languages, with the goals of developing bilingualism, strong academic abilities, and positive cross-cultural attitudes (Christian, 1996; LindholmLeary, 2001). There has been a surge in the popularity of these programs in the past 10 years, and they are currently receiving a great deal of attention. The incidence of two-way immersion remains highest in the United States, but programs are being implemented around the worldfor example, a Macedonian/Albanian program reported by Tankersley (2001). Gaps remain in the research base needed for guiding program design and implementation, however (Freeman, 1998; Tarone & Swain, 1995; Vald6s, 1997). For all dual-language approaches, questions arise related to schoolbased language instruction and the need to master content through, and literacy in, an L2 (August & Hakuta, 1997; Christian & Genesee, 2001). The acquisition of literacy competence as well as subject matter learning is a critical factor in academic success, and these processes need to be better understood when L2 learning is occurring at the same time (Crandall, 1992). Other important questions involve how to ensure language learning to high proficiency levels when the focus is primarily on content. Some critical research questions include
Phenothiazine-BODIPY-fullerene triads as photosynthetic reaction center models: substitution and solvent polarity effects on photoinduced charge separation and recombination.

Novel photosynthetic reaction center model compounds of the type donor2 -donor1 -acceptor, composed of phenothiazine, BF2 -chelated dipyrromethene (BODIPY), and fullerene, respectively, have been newly synthesized using multistep synthetic methods. X-ray structures of three of the phenothiazine-BODIPY intermediate compounds have been solved to visualize the substitution effect caused by the phenothiazine on the BODIPY macrocycle. Optical absorption and emission, computational, and differential pulse voltammetry studies were systematically performed to establish the molecular integrity of the triads. The N-substituted phenothiazine was found to be easier to oxidize by 60 mV compared to the C-substituted analogue. The geometry and electronic structures were obtained by B3LYP/6-31G(dp) calculations (for H, B, N, and O) and B3LYP/6-31G(df) calculations (for S) in vacuum, followed by a single-point calculation in benzonitrile utilizing the polarizable continuum model (PCM). The HOMO-1, HOMO, and LUMO were, respectively, on the BODIPY, phenothiazine and fullerene entities, which agreed well with the site of electron transfer determined from electrochemical studies. The energy-level diagram deduced from these data helped in elucidating the mechanistic details of the photochemical events. Excitation of BODIPY resulted in ultrafast electron transfer to produce PTZ-BODIPY(.+) -C60 (.-) ; subsequent hole shift resulted in PTZ(.+) -BODIPY-C60 (.-) charge-separated species. The return of the charge-separated species was found to be solvent dependent. In nonpolar solvents the PTZ(.+) -BODIPY-C60 (.-) species populated the (3) C60 * prior to returning to the ground state, while in polar solvent no such process was observed due to relative positioning of the energy levels. The (1) BODIPY* generated radical ion-pair in these triads persisted for few nanoseconds due to electron transfer/hole-shift mechanism.
Global response to radiation in prostate adenocarcinoma: examination of 12,000 genes and 48,000 ESTs following fractionated versus bolus radiation

Purpose: The success of clinical treatments, such as ionizing radiation (IR), depends in great part on their ability to induce programmed cell death (apoptosis). Since apoptosis is deregulated in most cancers, apoptotic-modulating therapies offer an attractive opportunity for clinical therapy of many tumors, including that of the prostate. To identify genes whose expression contributes to radiation induced apoptosis of prostate cancer (CaP), we used oligonucleotide microarray technology to interrogate the expression of 60,000 human genes and ESTs following bolus and fractionated radiation and the kinetic response of 12,000 genes over 24 hours at ten time points.
Privileged access, externalism, and ways of believing

By exploiting a concept called ways of believing, I offer a plausible reformulation of the doctrine of privileged access. This reformulation will provide us with a defense of compatibilism, the view that content externalism and privileged access are compatible.
Observation of dynamic correlations in collisional redistribution and depolarization of light

Theory shows that to explain the polarization of light collisionally redistributed from the far line wings of an atomic transition, one must consider correlated events in which absorption during a collision, and propagation to the final Zeeman-state superposition at the end of the collision is important. Polarizations of up to about 40% have been measured in the far line wings, substantially confirming this prediction, and showing that scattering experiments cannot just be characterized by simple absorption or emission profiles.
Targeted therapies: Denileukin diftitox--a step towards a 'magic bullet' for CTCL.

Investigators found that denileukin diftitox, which targets the interleukin-2 receptor, achieves objective response rates in 44% of patients with cutaneous T-cell lymphoma, with a median duration of response of 7.8 months and 2% incidence of severe vascular leak syndrome. The inclusion of a placebo arm in the study revealed several additional interesting observations.
A duplex structure involving two non-complementary DNA strands can be formed and stabilized by M13 phage proteins

Abstract M13 phage is a long, thin nucleoprotein filament containing a single-stranded DNA loop. Exposing the filaments to a chloroform/water interface at 20 °C causes them to contract into hollow spherical particles (spheroids), while exposure at low temperatures yields short, thick rods (I-forms). All of the DNA remains within the I-forms while a specific third remains within the spheroids. Here, a photo-crosslinking reagent, psoralen, has been used to probe secondary structure of the DNA in situ in these chloroform-relaxed phage forms. Following photo-crosslinking, the DNA that had been held within the spheroids appeared to be a duplex rod when seen by electron microscopy, while the DNA extruded from the spheroids was an open single-stranded DNA loop. Photo-crosslinking of the DNA in the I-forms yielded linear duplex DNA rods close to the length of M13 phage filaments. Similar observations derived from experiments with deletion and insertion mutant phage showed that the stability of the duplex rods did not depend on the sequence homology between the two opposing strands. These results showthat two non-homologous strands of DNA can exist in an apparently duplex structure and suggest that this is directed by proteins, possibly involving interaction at a membrane.
Synthesis of peptide derived amino alcohols II. Synthetic methodology for the preparation of tertiary alcohols

Abstract Synthetic methods are described for the preparation of a series of tripeptide derived aminoalcohols (i.e., 2 ). These novel peptidyl tertiary alcohols are potential inhibitors of angiotensin converting enzyme (ACE). The synthetic targets resemble acyltripeptide substrates for the enzyme, but contain a -CHOH(CH 3 )-CH 2 -NH- moiety, as replacement for the scissile amide bond.
New molecular insights into heart failure and cardiomyopathy: potential strategies and therapies

In the most severely affected patients the mortality for congestive heart failure exceeds that of many cancers. While therapies are largely aimed at attenuating neurohumoral responses recent molecular insights reveal other potential targets for therapy. To summarise some of the recent developments in the management of heart failure and provide the clinician who treats heart failure with new insights into emerging approaches. A literature review was conducted of the recent literature together with personal research data. Large randomised trials will provide a more comprehensive understanding of the interaction of β-blockers and other heart failure therapies with gene polymorphisms. Cytokines are important in the progression of heart failure, yet therapy aimed at blocking cytokine effects has not been successful. More selective use of anti-cytokine therapy may have beneficial effects. Gene therapy to improve heart failure has not yet reached clinical trials. The molecular genetics of hypertrophic and dilated cardiomyopathy is rapidly improving our understanding so that genetic diagnostics and counselling may soon be performed for patients and families. The emergence of a molecular based understanding of heart failure will hopefully improve therapy of this common condition.
Convergence rates for trigonometric and polynomial-trigonometric regression estimators

Abstract Upper bounds are derived for the rates of convergence for trigonometric series regression estimators of an unknown, smooth regression function. The resulting rates depend on the regression function satisfying certain periodic boundary conditions that may not hold in practice. To overcome such difficulties alternative estimators are proposed which are obtained by regression on trigonometric functions and low-order polynomials. These estimators are shown to always be capable of obtaining the optimal rates of convergence over a particular smoothness class of functions, irregardless of whether or not the regression function is periodic.
Learned stressor resistance requires extracellular signal-regulated kinase in the prefrontal cortex

Behaviorally controllable stressors confer protection from the neurochemical and behavioral consequences of future uncontrollable stressors, a phenomenon termed “behavioral immunization.” Recent data implicate neuroplasticity within the ventromedial prefrontal cortex (mPFC) as critical to behavioral immunization. Adult, male Sprague-Dawley rats were exposed to a series of controllable tailshocks and one week later to uncontrollable tailshocks, followed 24h later by social exploration and shuttlebox escape tests. To test the involvement of N-methyl-D-aspartate receptors (NMDAR) and the extracellular signal-regulated kinase (ERK) cascade in behavioral immunization, either D-AP5 or the MEK inhibitor U0126 was injected to the prelimbic (PL) or infralimbic (IL) mPFC prior to controllable stress exposure. Phosphorylated ERK and P70S6K, regulators of transcription and translation, were quantified by Western blot or immunohistochemistry after controllable or uncontrollable tailshocks. Prior controllable stress prevented the social exploration and shuttlebox performance deficits caused by the later uncontrollable stressor, and this effect was blocked by injections of D-AP5 into mPFC. A significant increase in phosphorylated ERK1 and ERK2, but not P70S6K, occurred within the PL and IL in rats exposed to controllable stress, but not to uncontrollable stress. However, U0126 only prevented behavioral immunization when injected to the PL. We provide evidence that NMDAR and ERK dependent plasticity within the PL region is required for behavioral immunization, a learned form of stressor resistance.

Time series versus cross-sectionally derived predictions of future cash flows

Abstract We refine the analysis of annual cash-flow prediction models originally developed and tested by Dechow et al. (1998), Barth et al. (2001) and Kim and Kross (2005) using cash flow from operations data reported in accordance with FASB Standard No. 95 for a constant sample of 1111 firms. We estimated annual cash-flow prediction models both cross-sectionally and on a time-series basis to assess whether restricting firm-specific parameter estimation in the cross-sectional approach adversely affects predictive performance. Predictive ability is assessed via “out-of-sample” forecasts in an inter-temporal holdout period (2001–2005) not used in model estimation. We provide new evidence that significantly greater enhancement to predictive performance is obtained when cash-flow prediction models are estimated on a time-series basis versus cross-sectionally. These inferences are robust across one-year ahead cash-flow predictions or one-thru-five-year ahead predictions. We find that the relative accuracy of cash-flow predictions is unaffected by whether the aforementioned prediction models employ cash flows or net earnings as independent variables. Finally, we also provide evidence that the predictive ability of cash flows is highly sensitive to firm size. That is, relatively larger firms provide significantly more accurate cash-flow predictions than those of smaller firms across cash-flow prediction models.
Responsible Conduct of Research in Audiology

The goal of science is knowledge. The goal of research is to draw inferences about a study sample and ultimately about the real world. The challenge is to minimize error. Adherence to scientific principles and accepted scientific practices minimizes error and facilitates accurate inferences. Research integrity and the responsible conduct of research is critical to the research process, maintaining trust in science, and preventing harm to those that research is meant to benefit. The responsible conduct of research in Audiology is reviewed here from the perspectives of an established researcher and a student investigator (i.e., doctoral candidate). The discussion begins with an illustrative vignette to spark contemplation and discussion of the topic. Ethical principles, regulations, and guidelines that promote research integrity are considered and additional materials for further study are provided.
Molecular Profiles of HCV Cirrhotic Tissues Derived in a Panel of Markers with Clinical Utility for Hepatocellular Carcinoma Surveillance

Background Early hepatocellular carcinoma (HCC) detection is difficult because low accuracy of surveillance tests. Genome-wide analyses were performed using HCV-cirrhosis with HCC to identify predictive signatures.
Prediction of red cell and blood volumes distribution by various nomograms: do current nomograms overestimate?

BACKGROUND: Currently used formulas for estimation of a person's red cell volume (RCV) by weight and height are decades old and were based on the use of 51Cr isotopes and on a sample population, which may not be reflective of today's population. In this study, the accuracy and precision of the use of 99mTc RCV measurements in volunteers more typical of today's population were evaluated. STUDY DESIGN AND METHODS: The subjects were volunteers who met the requirements for a standard blood donation. RESULTS: The mean ± standard deviation (SD) 99mTc RCV for 127 males (mean weight, 83.2 kg; height, 180 cm) was 2062 ± 339 mL, and for 101 females (mean weight, 69.5 kg; height, 166 cm) it was 1320 ± 201 mL. These results were highly correlated with RCV results with the standard extrapolation 51Cr method with stored red blood cells (RBCs) and highly consistent (within ±10%) by repeated measurements with the same 22 donors over a 3.5-year period. The RCV results correlated with estimates from the current formulas, but were on average 11 to 14 percent lower. CONCLUSION: The studies demonstrated that 99mTc is a reproducible and precise method for determination of a person's RCV and that current formulas may significantly overestimate the RCV of today's population. This is likely the result of a shift in population characteristics over the past four decades as reflected by an increased mean body mass index (from 25 to 28 kg/m2), which has not resulted in a proportionally increased RCV.
Teaching Racial Literacy in Secondary Humanities Classrooms: Challenging Adolescents' of Color Concepts of Race and Racism.

This article examines how three culturally relevant teachers in New York City public schools challenged the concepts of race and racism which low-income adolescents of color brought to the study of history and contemporary society. Framed by concepts of culturally relevant teaching and racial literacy, the study illustrated how the teachers used sustained and strategic instruction about race (Skerrett 2011) to complicate and challenge students’ ideas of race and racism. The authors conclude by examining the implications for teaching racial literacy in humanities classrooms with low-income students of color. They also explore how the teachers’ ‘alternate models of pedagogy’ (Ladson-Billings 1995) builds upon and extends the theory of culturally relevant pedagogy as it is commonly conceptualized.
Airway glutathione homeostasis is altered in children with severe asthma: Evidence for oxidant stress

Background Severe asthma is characterized by persistent airway inflammation and increased formation of reactive oxygen species. Objectives Glutathione (GSH) is an important antioxidant in the epithelial lining fluid (ELF). We hypothesized that airway GSH homeostasis was altered in children with severe asthma and was characterized by decreased GSH and increased glutathione disulfide (GSSG) concentrations. Methods Bronchoalveolar lavage was obtained from 65 children with severe asthma, including 35 children with baseline airway obstruction evidenced by FEV 1 2 O 2 were measured in the ELF. The ELF redox potential was calculated from GSH and GSSG by using the Nernst equation. Results Compared with controls, subjects with severe asthma had lower airway GSH with increased GSSG despite no differences in GST, GR, and GPx activities between groups. This was accompanied by increased malondialdehyde, 8-isoprostane, and H 2 O 2 concentrations in the ELF. GSH oxidation was most apparent in subjects with severe asthma with airway obstruction and was supported by an upward shift in the ELF GSH redox potential. Conclusion Children with severe asthma have increased biomarkers of oxidant stress in the ELF that are associated with increased formation of GSSG and a shift in the GSH redox potential toward the more oxidized state.
Personalities of Adults With Traumatic Childhood Separations

Objectives: This study examined personality characteristics and identified personality subtypes of adults with childhood histories of traumatic separations from a parent. Previous work from attachment theory and developmental psychopathology suggests that distinct developmental trajectories might lead to different styles of personality adaptation after an attachment disruption. Design: Randomly selected psychologists and psychiatrists provided data on 203 adults with histories of traumatic separations using a personality pathology instrument designed for use by clinically experienced observers, the Shedler-Westen Assessment Procedure (SWAP-II). Results: Using a Q-factor analysis, 5 distinct personality subtypes were identified: internalizing/avoidant, psychopathic, emotionally dysregulated, hostile/paranoid, and resilient. Initial support for the validity of the subtypes was established, based on Axis I and Axis II pathology, adaptive functioning, developmental history, and family history variables. Conclusions: Both therapeutic interventions and case formulation might be strengthened by considering an individual’s personality features and match to one of the identified subtypes. & 2011 Wiley Periodicals, Inc.

Tissue‐specific expression of type XII collagen during mouse embryonic development

Polyclonal antibodies were raised in rabbits against a fusion peptide representing a portion of the amino-terminal non-triple-helical domain of mouse type XII collagen. The antibodies reacted with bands of 220 and 350 kDa on Western blots of mouse tissue extracts. Immunohistochemical analyses of mouse embryos demonstrated that type XII collagen is expressed mainly in dense connective tissues of tendons, ligaments, dermis, cornea, blood vessel walls, meninges, and developing membranous bones. Comparison of skin extracts and medium of cultured mouse skin fibroblasts by Western blotting showed that while tissue contain short 220 kDa type XII collagen polypeptides as well as the long form, cultured cells produce mainly the long form with 350 kDa polypeptides.
Self-evaluation and self-perception: The role of attention in the experience of anxiety

Self-awareness promotes the experience of anxiety in two ways. It does so directly, by enhancing awareness of the emotional state itself, and by initiating the self-evaluation process that is necessary for anxiety to occur. It also does so indirectly, by constraining some behaviors and inhibiting others. In particular, it increases accuracy of self-perception, and, in so doing, retards the process of self-delusion. This is important, because the latter process has been shown to have a salutary effect on mental health, acting as a buffer against dysphoric states such as depression and anxiety.
Impact of oxygen and argon plasma exposure on the roughness of gold film surfaces

Abstract The impact of oxygen and argon plasma exposure on the roughness of gold film Quartz Crystal Microbalance (QCM) electrodes is reported here, employing low levels of gas uptake and scanning tunneling microscope measurements to probe the post-exposure surface morphology. For equal exposure times, argon plasma bombardment is observed to produce both greater material removal and greater change in surface roughness. A possible explanation for this is that the oxygen plasma produces a protective gold oxide layer, which may remove the contaminants from the surface without creating defects in the gold surface. The result is also consistent with prior reports of chemical cleaning of the surface by reactive oxygen ions. Pentane gas adsorption on the argon bombarded QCM surfaces was, moreover, observed to occur at pressures that are several orders of magnitude lower than that for an unbombarded surface.
Hintikka on the Foundations of Mathematics: IF Logic and Uniformity Concepts

The initial goal of the present paper is to reveal a mistake committed by Hintikka in a recent paper on the foundations of mathematics. His claim that independence-friendly logic (IFL) is the real logic of mathematics is supported in that article by an argument relying on uniformity concepts taken from real analysis. I show that the central point of his argument is a simple logical mistake. Second and more generally, I conclude, based on the previous remarks and on another standard fact of IFL, that first-order logic (FOL) can adequately express uniformity concepts in real analysis, whereas IFL (understood as a non-trivial extension of FOL) cannot. This not only radically contradicts Hintikka’s particular claim in that article, but also undermines his whole enterprise of founding mathematics on his logic system.
Blanket Warming: Comfort and Safety

ABSTRACT A project was undertaken to establish the safety of hospital blankets warmed at different temperatures in a warming cabinet. Three volunteers were covered with unheated blankets, blankets warmed to 110° F (43° C), and blankets warmed to 150° F (66° C). Evaluators asked the participants to rate their perceived warmth and perceived comfort on a scale of zero to 10 before the blanket was placed and at one, three, and five minutes after blanket exposure. Blanket temperatures decreased to approximately 80° F (27° C) within five minutes regardless of the initial temperature. No participants perceived overheating or burning at any temperature. Perceived warmth and comfort increased with the initial temperature of the blanket. AORN J 89 (April 2009) 717–722. © AORN, Inc, 2009.
Radiomimetric assay of acetylcholinesterase activity in submicrogram amounts of tissue

A radiometric procedure for the estimation of cholinesterase activity was described which measures acetate-1-14C after the selective removal of the unhydrolyzed substrate, acetyl-1-14C-choline, as an insoluble reinecke salt. Its sensitivity is adequate for the assay of 0.05 μg (protein) brain tissue. The convenience has been illustrated by various kinetic studies, including the inhibition by acetylthiocholine. A detailed comparison with other radiometric methods was presented.
Analytic study of 2D and 3D grid motion using modified Laplacian

The modified Laplacian has been used to move unstructured grids in response to changes in the surface grid for a variety of grid movement applications including store separation, aero-elastic wing deformation and free surface flow simulations. However, the use of the modified Laplacian can result in elements with negative areas/volumes, because it has no inherent mechanism to prevent inversion of elements. In this paper, the use of a modified Laplacian is studied analytically for a two-dimensional problem of deforming the inner circle of two concentric circles and for a three-dimensional problem of deforming the inner sphere of two concentric spheres. By analysing the exact solution for this problem, the amount of translation and deformation of the inner circle that maintains a valid mesh is determined. A general grid movement theorem is presented which determines analytically the maximum allowable deformation before an invalid mesh results. Under certain circumstances, the inner circle and sphere can be expanded until it reaches the outer circle or sphere, while remaining a valid grid, and the inner circle and sphere can be rotated by an extreme amount before failure of the mesh occurs. By choosing the exponent to the modified Laplacian appropriately, extreme deformations for single frequency deformations is possible, although for practical applications where the grid movement has multiple frequencies, choosing the optimal exponent for the modified Laplacian may not be practical or provide much improvement. For grid movement simulations involving rigid body translation and rotation or uniform expansion, the modified Laplacian can yield excellent results, and the optimum choice of the modified Laplacian can be analytically determined for these types of motions, but when there are multiple frequencies in the deformation, the modified Laplacian does not allow much deformation before an invalid grid results.

Corporate social performance and financial‐based brand equity

Purpose – The purpose of this research is to empirically test the interrelationship between corporate social performance and financial‐based brand equity. This paper proposes that social performance leads to enhanced brand equity and, conversely, brand equity positively influences social performance. Firm size is hypothesized to play a moderating role in the interrelationship.Design/methodology/approach – This paper uses cross‐sectional, secondary data of global brands. A system of equations is proposed and estimated using seemingly unrelated regression.Findings – Prior social performance has a positive effect on brand equity, but brand equity only impacts future social performance among very large firms. The positive effect of prior social performance on brand equity is amplified in smaller firms.Practical implications – Managers can increase brand equity by using corporate social responsibility as a strategic tool for positioning differentiation. To maintain competitive parity in social positioning and ...
A knowledge-based system for MVS dump analysis

A new domain in software problem determination can be automated by means of this knowledge-based system. The system imitates a human problem solver by using the same tools and the same diagnostic approach as the experts use, including the processing of human-readable data. The application is fully integrated within the target Multiple Virtual Storage (MVS) operating system to ensure user acceptance. A large variety of knowledge is contained in the system, ranging from pattern-recognition knowledge to basic MVS knowledge and problem-solving strategies. The diagnostic approach is based on a model of software problem situations and on diagnostic reasoning methods adopted from the medical application domain. The goal of the project was to solve a significant part of the problem resolution process automatically, rather than to build yet another tool for use in software problem determination. This system is a first step to further automation in this area.
Leadership in research across academia and practice

Transcript of a keynote address delivered by John McRae at the 2009 ARCC Architectural Research Conference at the University of Texas San Antonio.I value very much the award and I certainly have truly enjoyed the time and the meeting these couple of days has been extremely stimulating. We were talking several of us ahead of time about the rigor and the intensity with which the programs are being presentedin each of the meetings. We really, I think, have the group here that’s going to be serving us well for thefuture.I want to also say today, in expressing my appreciation for this award, that the list of past awardees is stellarand includes several colleagues and personal friends towhom I owe a debt in my professional development and am grateful for the opportunity to address the conference and hope that my remarks with be of even a small benefit to our collective efforts to strengthen research across academia and practice. I started my career in both academia and practice in 1967, little more than the 30 years you were so gracious to give me, in Gainesville and at the University of Florida. Over this span of the last 42 years I have sought to develop my own research and creative work agenda and, through administrative roles, have made an effort to foster the research of colleagues when I could. So what was it like in the late 60’s and early70’s? Some of you may recall. In the interest of full disclosure, I have included a few images of my research work during my early years as a faculty member at the University of Florida. And so, here is another shot of our research team. Some of you may remember the Chicago 7. This is the rainbow 9 and, in fact, aside from myself, whom you will recognize, there are several other people there who are today in positions helping to lead this nation. That is kind of hard to imagine but there they are.
Coagulation studies in children with isolated recurrent epistaxis

IN 1 9 5 9, Schulman I reported on 34 children with recurrent epistaxis. Seventeen of these children had no personal or family history suggestive of a bleeding disorder. No coagulation abnormalities were found in this group. The other 17 children had multisymptomatic bleeding histories, or positive family history for a coagulation disorder, and all but one were shown to have hemorrhagic disorders. Schulman concluded that isolated, recurrent epistaxis was unlikely to be associated with coagulation disorders. In the past 20 years, advances in understanding and technology have increased our ability to identify mild bleeding disorders. We elected to re-evaluate prospectively a gr6up of children specifically referred for evaluation of isolated, recurrent epistaxis, to determine whether or not a significant number of youngsters with this problem have a mild bleeding disorder.
Temperature-dependent study of the interfacial resistances in polysilicon-emitter contacts

From a comparison of the functional dependences of the measured interfacial resistance with those simulated by a rigorous numerical computer calculation, a triangular-shaped potential barrier is inferred for those interfacial layers having an RCA-clean surface treatment. It is conjectured that the triangular shape is linked to the dopant pile-up at this interfacial layer. >
The benefits of electronic records management systems: a general review of published and some unpublished cases

Purpose – To review published case studies, and some unpublished results, to identify the benefits actually achieved by implementing an electronic records management system or an electronic document management system (ERMS, or EDMS).Design/methodology/approach – Draws on the literature and unpublished results of work undertaken by the authors’ organisation.Findings – Few case studies were found in which clear, quantitative benefits are described. The reasons for this are discussed. Those studies that did show clear benefits with good evidence for them demonstrated five principles: (1) the “system” must include the people (policy makers and users); (2) the EDRMS must be integrated with the processes of the organisation; (3) frequently the role of records managers is to educate, advise and support the users; (4) a continuum model covering documents and records gives clearer benefits than separate document and record lifecycles; and (5) there is no single magic bullet to solve information management problems...
Latinos in the USA: Changing socio-economic patterns

This paper aims to provide an overview of socio-economic inequality experienced by Latinas and Latinos, suggesting that the increase in numbers and their dispersal throughout the country disrupts the traditional black–white paradigm used in race relations theory. Instead, I argue that the particular historical and geographical experiences of Latinas/os portend complex changes within labour markets and neighbourhoods and across families, ultimately challenging how we think about race relations in the USA.
Stereotactic Radiosurgery for Patients with Solid Brain Metastases: Current Status

The goal of this article is to provide a contemporary update on the use of stereotactic radiosurgery (SRS) for the treatment of intracranial metastatic disease. We discuss the rationale for employing SRS in brain metastases and describe the critical factors that predict outcome. We highlight the main clinical indications for SRS including treatment of recurrent brain metastases after previous whole brain radiation therapy (WBRT), as a boost after WBRT, and as sole therapy for newly diagnosed tumors. For each clinical scenario, we offer a treatment algorithm based on our clinical experience. The article also addresses the most common complications associated with SRS and their treatment.
Submarine metamorphism of gabbros from the Mid-Cayman rise: An oxygen isotopic study

Abstract Oxygen isotopic compositions of minerals in 22 samples of submarine gabbros were determined. The gabbros were collected using the submersible Alvin from the 700 m vertical section of the rift-valley wall of the Mid-Cayman spreading center. Our study indicates that in the Mid-Cayman Rise seawater barely reached the bottom of the plutonic layer. Abundant seawater penetration (water/rock mass ratio > 1) was limited to the upper part of the plutonic layer. From the observed oxygen isotopic compositions of coexisting minerals, and from the experimental and empirical determinations of equilibrium fractionation of oxygen isotopes for mineral-water, and mineral-mineral pairs, we show the following: (1) pyroxene and olivine did not exchange oxygen with seawater, (2) plagioclase is in isotopic disequilibrium with pyroxene; (3) the rate of oxygen exchange in plagioclase was not slowed by the absence of cation exchange; (4) plagioclase and amphibole have exchanged oxygen with seawater or isotopically modified seawater (δ18O ≤ 3%.); and (5) amphibole has exchanged or acquired (during formation) hydrogen from seawater at 380°C ≤ T ≤ 600°C. The decrease in extent of isotopic exchange of plagioclase and the decrease in amphibole abundance with depth indicate that seawater flux decreased rapidly with depth (water/rock mass ratio falling from 1.7 to 0.2 over a 300 m interval).
Pain assessment index: Evaluationfollowing multidisciplinary pain treatment

Abstract The Pain Assessment Index is a weighted composite of MMPI scales which has been shown tobe useful in predicting surgical outcome for chronic pain patients. In this study, 48 patients treated at a nonsurgical multidisciplinary pain clinic were categorized into predicted success (N=23) or predicted failure (N=25) groups based on their PAI scores. The groups did not differ on any of the pretreatment variables, and they differed on only one follow-up outcome measure. More patients in the predicted failure group reported using narcotics than did their predicted success group counterparts. Implications of these results and recommendations for future research are discussed. J Pain Sympt Manag 1987;2:23–27.
Collapsing glomerulopathy: Many means to a similar end

Collapsing glomerulopathy (CG) represents a morphologic pattern of disease, characterized histologically by glomerular capillary collapse, severe podocyte injury, and glomerular epithelial cell proliferation, and clinically by marked proteinuria and renal insufficiency. CG has multiple etiologies; however, many questions remain about its pathogenesis. A new set of animal models of CG, characterized by absence of the normal podocyte cytoskeletal protein α-actinin-4, has potential to help us gain a greater understanding of cellular events involved in producing this pattern of disease.
MEMS actuators for boundary layer control of micro-rotor blades

This paper presents on-going research directed towards the development of MEMS actuators for improved aerodynamic efficiency of micro-rotorcraft. A 6 inches diameter micro-rotor system was developed and tested in hover. Results indicated that profile power losses associated with low Reynolds number viscous flows and flow separation and stall at high angles of attack limit the rotor performance at micro-scale. It is envisaged that tripping the flow from laminar to turbulent at the leading edge of the rotor blade can prevent formation of the laminar separation bubble and improve lifting efficiency of the micro-rotor. This study will present the design of a prototype MEMS actuator (piezoelectric thin film). It is envisaged that multiple arrays of such MEMS devices can be assembled on the surface of the airfoil section to create a smart skin. The smart skin when actuated provides controllable surface roughness that can be used to enable premature boundary layer transition.
Regulation of proliferation, invasion and growth factor synthesis in breast cancer by steroids.

Endogenous ovarian estrogens and progestins appear to play a critical role in the development and progression of breast cancer. Local productions of growth factors probably also contribute to malignant proliferation, while production and activation of collagenolytic enzymes may be equally critical for local invasive processes. The current review focusses on characterization of growth factor-receptor systems operant in normal and malignant breast epithelium. In addition, the determinants of local invasion are reviewed: attachment, modality, and proteose secretion. Finally, data are discussed concerning the regulation of both proliferation and invasion by hormones and antihormonal agents in hormone-dependent breast cancer. The results suggest new potential pharmacologic targets to explore to suppress onset and progression of breast cancer.
