Leader LPC and follower satisfaction: A review

Abstract Research relating follower satisfaction to the leader's score on Fiedler's Least Preferred Co-Worker (LPC) scale was reviewed. Available data suggest that contingency model research using follower satisfaction as a measure of leadership effectiveness yields results with a level of orderliness and replicability quite comparable to the group task performance measures usually considered by the model. The motivational hierarchy and value-attitude interpretations of LPC were considered as alternative explanations for this pattern of results. The implications of including follower satisfaction as a second measure of leadership effectiveness within the contingency model framework was discussed in terms of both theoretical extensions and organizational practices based on the theory.
Stimulation of Chick Growth with Alfalfa Concentrates

Abstract NOVAK et al. (1953) observed that a factor(s) was present in dehydrated alfalfa leaf meal which stimulated growth of the mold, Neurospora sitophila. This factor(s) was distinct from thiamine, folic acid, biotin, para-aminobenzoic acid, vitamin B12, riboflavin, niacin, and inositol. Concentration of this factor(s) was reported by Novak, Jonnard and Liuzzo (1958), employing this mold as a test organism for evaluating and comparing the degree of activity in the various fractions. These investigators obtained a final active concentrate which represented less than 0.1% of the solids. This study was proposed to test the growth stimulating effects of these alfalfa concentrates on chicks, since numerous investigations have indicated the presence of an unidentified growth factor(s) in alfalfa for the chick (Kohler and Graham, 1951; Hansen et al., 1953; Jacobs et al., 1953; Scott et al., 1953; Vavich et al., 1953; Fisher et al., 1954). EXPERIMENTAL PROCEDURE The growth stimulating effects of …
Mercury Porosimetry in Mesoporous Glasses: A Comparison of Experiments with Results from a Molecular Model

We present results from experiments and molecular modeling of mercury porosimetry into mesoporous Vycor and controlled pore glass (CPG) solid materials. The experimental intrusion/extrusion curves show a transition from a type H2 hysteresis for the Vycor glass to a type H1 hysteresis for the CPG. Mercury entrapment is observed in both materials, but we find that the amount of entrapped mercury depends on the chosen experimental relaxation time. No additional entrapment is found in a second intrusion/extrusion cycle, but hysteresis is still observed. This indicates that hysteresis and entrapment are of different origin. The experimental observations are qualitatively reproduced in theoretical calculations based on lattice models, which provide significant insights of the molecular mechanisms occurring during mercury porosimetry experiments in these porous glasses.
A catalytic reaction on alumina studied by tunneling spectroscopy: Transfer hydrogenation of muconic acid☆

Abstract Tunneling spectroscopy is a sensitive method for studying the catalytic properties of alumina which grows thermally on an aluminum strip. We observe controlled catalytically induced transfer hydrogenation from water vapor of muconic acid, a conjugated hydrocarbon chain chemisorbed on the alumina with carboxylate groups at both ends. Between 25 and 400 °C the amount of hydrogen transferred grows exponentially with temperature; in the range of parameters accessible to us the reaction is time independent and only weakly pressure dependent. Hydrogen is transferred from the water vapor through hydroxyl groups on the surface. The reaction does not go to completion at a fixed temperature because it runs out of available surface hydrogen.
Connectionism and the problem of systematicity (continued): why Smolensky's solution still doesn't work.

Abstract Paul Smolensky has recently announced that the problem of explaining the compositionality of concepts within a connectionist framework is solved in principle. Mental representations are vectors over the activity states of connectionist “units”, but the vectors encode Classical trees, whose structural properties in turn “acausally” explain the facts of compositionality. This sounds suspiciously like the offer of a free lunch, and it turns out, upon examination, that there is nothing to it.
From computer‐aided manufacturing to Japanese newspapers: evolution of the AAU/ARL Japan Journal Access Project

The AAU/ARL (Association of American Universities/Association of Research Libraries) Japan Journal Access Project seeks to expand access to research materials published in Japan, and to coordinate collection development activities of Japanese‐language material held by North American research libraries. Established in 1994, the focus of the Japan Project has evolved from providing access to scientific and technical serials published in Japan to providing access to Japanese language materials held by Japanese and North American libraries. The Union List of Japanese Serials and Newspapers and the Association of National University Libraries (ANUL) and Waseda document‐delivery projects have emerged as key activities. Collaborative collection development remains an important, but unrealized, goal. Suggestions for future developments are made.
The toroid cavity NMR detector

Abstract A cylindrical toroid cavity has been developed as an NMR detector for investigations at high temperature and high pressure in metal vessel probes. With toroid cavity detectors, resonance frequencies up to 400 MHz can easily be attained, which makes them particularly useful for high-field 1 H and 19 F spectroscopy. Typically, static half-height linewidths of 1.5 Hz are achieved, as measured on 1 H with standard solutions in cylindrical pressure vessels. Based on the radial dependency of the B 1 field inside a toroid detector, a mathematical equation was derived that precisely predicts the signal intensity as a function of the pulse width. Inversion-recovery measurements of the T 1 relaxation time of compressed gases (methane and hydrogen) were conducted by using composite inversion pulses. The results demonstrated the utility of toroid cavities for quantitative measurements in pressure probes. Pressures up to 300 bar have been used successfully. Because of the strength and regularity of the B 1 gradient, the toroid cavity detector is also suitable for one dimensional rotating-frame NMR microscopy. A spatial resolution down to a few micrometers can be achieved. The spin concentration and spatial distribution of a chloroform solution were accurately reconstructed from two-dimensional 1 H NMR data. Another similarly accurate but even stronger B 1 gradient evolves as a result of the skin effect during high-frequency current transmission inside the central conductor. This gradient makes it possible to perform rotating-frame microscopy inside the central conductor, as demonstrated with 63 Cu NMR spectroscopy.
Automated extensible XML tree diagrams

XML is a tree-oriented meta-language and understanding XML structures can often involve the construction of visual trees. These trees may use a variety of graphics for chosen elements and often condense or elide sections of the tree to aid focus, as well as adding extra explanatory graphical material such as callouts and cross-tree links. We outline an automated approach for building such trees with great flexibility, based on the use of XSLT, SVG and a functional layout package. This paper concentrates on techniques to declare and implement such flexible decoration, rather than the layout of the tree itself.
Solanum viarum: Weed reservoir of plant viruses in Florida

Abstract Solanum viarum Dunal (tropical soda apple), an introduced and rapidly spreading weed, currently infests over 60 000 ha in Florida. Approximately 220 plants were sampled in seven stands of S. viarum in south‐west and west central Florida during 1992 and 1993 to determine the occurrence of nine viruses which can infect solanaceous crops. Virus detection utilized a double antibody sandwich‐enzyme linked immunosorbent assay, or a nucleic acid spot hybridization assay. The viruses detected included cucumber mosaic virus (CMV), potato leaf roll virus (PLRV), potato virus Y (PVY), tobacco etch virus (TEV), tomato mosaic virus (ToMV), and tomato mottle virus (TMoV). Transmission of PVY and ToMV from S. viarum produced a range of symptoms in pepper, tobacco, and tomato. Isolates of TEV from pepper, and PVY and TMoV from tomato were transmitted to S. viarum. Solanum viarum was also naturally infected in the field by Altemaria solani Sorauer and infested by Colorado potato beetles (Leptinotarsa decenlineata...
Complex wave-field reconstruction using phase-space tomography.

A method is proposed for the experimental determination of the amplitude and phase structure of a quasimonochromatic wave field in a plane normal to its propagation direction. The wave field may represent either a scalar electromagnetic (EM) field or the quantum mechanical (QM) wave function of a matter wave. For coherent EM fields or pure QM states, the method uniquely reconstructs the complex wave fields. For partially coherent EM fields or mixed QM states, it reconstructs the two-point correlation function or density matrix. The experiment uses only intensity measurements and refractive optics (lenses), and the data analysis algorithm is noniterative and requires no deconvolution.
Therapy without diagnosis.

To the Editor: In gastroenterology, as in medicine or other craftsmanship, diagnosing the problem constitutes the more difficult part, whereas therapy itself constitutes the easier part of repair. Therapy may involve high technology, intricate instruments, and sophisticated drug regimens, but all this complexity is usually applied in a predetermined and standardized manner by following a fixed recipe. It can all be looked up, and most of the time the physician does not have to develop much individual ingenuity, creativity, or imagination. However, finding a correct diagnosis resembles a detective’s work with no marked paths or guarantees of success. It is time-consuming, unpredictable, mentally challenging, fraught with errors, and often frustrating. No wonder physicians try to avoid or outsource it. Gastroenterologists are inundated with consults for the work-up of weight loss, abdominal pains, diarrhea, or anemia, just to name a few. Frequently, there is not even the slightest effort by the referring physician to develop a list of differential diagnoses, let alone to rule out the most common or obvious contenders on such a list. The general tendency to avoid any engagement in the challenging and cumbersome process of finding the underlying cause of symptoms also expresses itself in treatment without a clear diagnosis (1). Is there any justification for such an approach?
The impact of noise on the reliability of heart-rate variability and complexity analysis in trauma patients

This study focused on the impact of noise on the reliability of heart-rate variability and complexity (HRV, HRC) to discriminate between different trauma patients and to monitor individual patients. Life-saving interventions (LSIs) were chosen as an endpoint because performance of LSIs is a critical aspect of trauma patient care. Noise was modeled and simulated by modifying original R-R interval (RRI) sequences via decimation, concatenation, and division of RRIs, as well as R-wave detection using the electrocardiogram. Results showed that under increasing simulated noise, entropy and autocorrelation measures can still effectively discriminate between LSI and non-LSI patients and monitor individuals over time.
A method to replicate the microstructure of heart tissue in vitro using DTMRI-based cell micropatterning.

A novel cell culture methodology is described in which diffusion tensor magnetic resonance imaging (DTMRI) and cell micropatterning are combined to fabricate cell monolayers that replicate realistic cross-sectional tissue structure. As a proof-of-principle, neonatal rat ventricular myocyte (NRVM) monolayers were cultured to replicate the tissue microstructure of murine ventricular cross-sections. Specifically, DTMRI-measured in-plane cardiac fiber directions were converted into soft-lithography photomasks. Silicone stamps fabricated from the photomasks deposit fibronectin patterns to guide local cellular alignment. Fibronectin patterns consisted of a matrix of 190 μm2 subregions, each comprised of parallel lines 11–20 μm-wide, spaced 2–8.5 μm apart, and angled to match local DTMRI-measured fiber directions. Within 6 days of culture, NRVMs established confluent, electrically coupled monolayers, and for 18 μm-wide, 5 μm-spaced lines, directions of cell alignment in subregions microscopically replicated DTMRI-measurements with a local error of 7.2 ± 4.1°. By adjusting fibronectin line widths and spacings, cell elongation, gap junctional membrane distribution, and local cellular disarray were altered without changing the dominant directions of cell alignment in individual subregions. Changes in the anisotropy of electrical propagation were assessed by optically mapping membrane potentials. This novel methodology is expected to enable systematic studies of intramural structure–function relationships in both healthy and structurally remodeled hearts.
Entamoeba histolytica and Giardia lamblia: effects of cysteine and oxygen tension on trophozoite attachment to glass and survival in culture media.

Abstract Attachment of Entamoeba histolytica and of Giardia lamblia trophozoites to glass was monitored during the culture cycle. Attachment of each parasite was greatest during the exponential phase of axenic growth. The effects of l -cysteine upon the kinetics of attachment of trophozoites to glass were determined quantitatively. Attachment in complex growth media required cysteine, even under N2, atmosphere. With cysteine, the rates of attachment were greatest for the first 2 hr, then continued more slowly. The numbers of attached trophozoites decreased immediately upon exposure to medium without cysteine. The role of cysteine in protecting trophozoites of both species from the lethal effects of oxygen was assessed using clonal growth in agar or agarose medium to determine viability following exposure to varying oxygen tensions in liquid medium. Cysteine was required for viability of trophozoites. Without cysteine, decreasing the oxygen tension prolonged survival. Under increased oxygen tension, cysteine delayed the onset of exponential killing. Although it has no thiol reducing group, l -cystine similarly protected E. histolytica.
Are There EEG Correlates of Mental States in Animals

The thesis of this paper emerges from the fact that mental states are generated by neural processes that also produce an associated electroencephalogram (EEG). Thus, it is logical to expect correlatio
What's in it for me? Using expectancy theory and climate to explain stakeholder participation, its direction and intensity

Abstract Expectancy theory explains motivation on the degree to which an effort is perceived to lead to performance, performance leads to rewards, and the rewards offered are desirable. In this article, we draw on expectancy theory along with psychological and organizational climate research to understand whether and to what degree stakeholders will participate in the implementation of project management systems and complimentary software technologies. We contend that psychological and organizational climate influence perceptions relevant to expectancy, that in turn determine: a) whether or not stakeholders will participate in a project, b) whether they will help or harm the project, and c) whether a stakeholder is motivated to complete these actions. Data for the article is from three in-depth case studies. Results support that stakeholders assess the direction and strength of the psychological climate and that their assessments shape their motivation to participate in active support, token support, or counter-implementation actions.
A GENERALIZED BOUNDARY-ELEMENT METHOD FOR STEADY-STATE HEAT CONDUCTION IN HETEROGENEOUS ANISOTROPIC MEDIA

Abstract A generalized boundary integral equation (BIE) is formulated for heat conduction problems in anisotropic media with spatially varying thermal conductivities arising from material heterogeneity. The generalized integral equation is expressed in terms of contour integrals only. This is accomplished with the aid of a generalized fundamental solution E and with the definition of a singular nonsymmetric generalized forcing function, D. Generalized fundamental solutions, E, are derived as locally radially symmetric responses to this nonsymmetric singular forcing function, D. Both E and D are defined in terms of the thermal conductivity of the medium. Although it is locally radially symmetric about the source point, E varies within the domain as the source point changes position. Examples of generalized fundamental solutions are provided for various thermal conductivities along with the corresponding forcing function, D. Numerical implementation is discussed. Numerical results are provided for several e...
International Sourcing and Supply Chain Stability

An international supply chain is conceptualized as a complex, dynamic system in which disruptions interact with long shipping and lead times to generate costs. Findings from a case study and simulation model indicate that demand-related disruptions created substantial and unexpected costs in terms of expedited shipping, high inventories, and lower demand fulfillment. Production-related disruptions declined over time, but demand-related disruptions did not. Implications for management are discussed.

The Conserved SKN-1/Nrf2 Stress Response Pathway Regulates Synaptic Function in Caenorhabditis elegans

The Nrf family of transcription factors plays a critical role in mediating adaptive responses to cellular stress and defends against neurodegeneration, aging, and cancer. Here, we report a novel role for the Caenorhabditis elegans Nrf homolog SKN-1 in regulating synaptic transmission at neuromuscular junctions (NMJs). Activation of SKN-1, either by acute pharmacological treatment with the mitochondrial toxin sodium arsenite or by mutations that cause constitutive SKN-1 activation, results in defects in neuromuscular function. Additionally, elimination of the conserved WD40 repeat protein WDR-23, a principal negative regulator of SKN-1, results in impaired locomotion and synaptic vesicle and neuropeptide release from cholinergic motor axons. Mutations that abolish skn-1 activity restore normal neuromuscular function to wdr-23 mutants and animals treated with toxin. We show that negative regulation of SKN-1 by WDR-23 in the intestine, but not at neuromuscular junctions, is necessary and sufficient for proper neuromuscular function. WDR-23 isoforms differentially localize to the outer membranes of mitochondria and to nuclei, and the effects of WDR-23 on neuromuscular function are dependent on its interaction with cullin E3 ubiquitin ligase. Finally, whole-transcriptome RNA sequencing of wdr-23 mutants reveals an increase in the expression of known SKN-1/Nrf2-regulated stress-response genes, as well as neurotransmission genes not previously implicated in SKN-1/Nrf2 responses. Together, our results indicate that SKN-1/Nrf2 activation may be a mechanism through which cellular stress, detected in one tissue, affects cellular function of a distal tissue through endocrine signaling. These results provide insight into how SKN-1/Nrf2 might protect the nervous system from damage in response to oxidative stress.
The 2011 Tuscaloosa Tornado: Integration of Pediatric Disaster Services into Regional Systems of Care

Objective To empirically describe the integration of pediatric disaster services into regional systems of care after the April 27, 2011, tornado in Tuscaloosa, Alabama, a community with no pediatric emergency department or pediatric intensive care unit and few pediatric subspecialists. Study design Data were obtained in interviews with key informants including professional staff and managers from public health and emergency management agencies, prehospital emergency medical services, fire departments, hospital nurses, physicians, and the trauma program coordinator. Results A single hospital in Tuscaloosa served 800 patients on the night of the tornado. More than 100 of these patients were children, including more than 20 with critical injuries. Many children were unaccompanied and unidentified on arrival. Resuscitation and stabilization were performed by nonpediatric prehospital and emergency department staff. More than 20 children were secondarily transported to the nearest children's hospital an hour's drive away under the care of nonpediatric local emergency medical services providers. No preventable adverse events were identified in the resuscitation and secondary transport phases of care. Stockpiled supplies and equipment were adequate to serve the needs of the disaster victims, including the children. Conclusion Essential aspects of preparation include pediatric-specific clinical skills, supplies and equipment, operational disaster plans, and interagency practice embedded in everyday work. Opportunities for improvement identified include more timely response to warnings, improved practices for identifying unaccompanied children, and enhanced child safety in shelters. Successful responses depended on integration of pediatric services into regional systems of care.

Choosing a Values-Based Leader: An Experiential Exercise.

Scandals throughout corporate America have encouraged companies to seek leaders who can sustain profitability and embody positive values within the organization. This group exercise highlights some of the key challenges involved in choosing a values-based leader. Participants assess three hypothetical companies' values during a period of change and then select one of six potential candidates for the CEO position based on the alignment between individual, leader, and organizational values. The exercise may be used in undergraduate, master of business administration (MBA), and executive MBA classes. Participants have especially enjoyed the surprises that emerge during the debriefing stage.
Application of the p‐version of the finite element method to elastoplasticity with localization of deformation

In this paper we discuss the use of the p-version of the finite element method applied to elastoplastic problems that exhibit sharp (but continuous) deformation gradients. The deformation theory of deviatoric, linearly hardening elastoplasticity with an iterative, displacement based finite element framework is used. The focus of this work is on assessing the applicability of the p-version to the analysis of localized deformation with continuous strain and displacement fields. Presented examples demonstrate that the method can be used reliably with a proper finite element mesh design. Possible extensions of the work are also discussed.

Kinetic studies of the stability of Pt for NO oxidation: Effect of sulfur and long-term aging

Abstract The stability of Pt catalysts for NO oxidation was analyzed by observing the effect of pre-adsorbed sulfur on the reaction kinetics using a series of Pt/SBA-15 catalysts with varying Pt particle sizes ( ca 2–9 nm). Our results indicate that sulfur addition did not influence catalyst deactivation of any of the Pt catalysts, resulting in unchanged turnover rates (TOR) and reaction kinetics. The presence of sulfur on Pt was confirmed by X-ray absorption fine structure spectroscopy (EXAFS) under reducing environments. However, exposure of the catalyst to NO oxidation conditions displaced sulfur from the first coordination shell of Pt, yielding Pt–O bonds instead. Re-reduction fully recovered the Pt–S backscattering, implying that sulfur remained near the Pt under oxidizing conditions. X-ray photoelectron spectroscopy (XPS) and chemisorption measurements confirmed the presence of sulfur near platinum. The invariance of the NO oxidation reaction to sulfur poisoning is explained by sulfur displacement to interfacial sites and/or sulfur binding on kinetically irrelevant sites. Formation of Pt oxides remains as the main source of catalyst deactivation as observed by kinetic and X-ray absorption spectroscopy (XAS) measurements.
SERS-based viral fingerprinting: current capabilities and challenges

Silver nanorod array substrates are fabricated by oblique angle deposition and characterized for optimal SERS performance. Using UV-visible-NIR spectrophotometry we show that the nanorods have a transverse surface plasmon resonance mode at ~357 nm and a broad absorbance spanning 600-800 nm when excited along the longitudinal direction. We demonstrate that SERS enhancement is optimized using an excitation wavelength of 633 or 785 nm. The large area uniformity in SERS signal (<10% variation) and reproducibility among preparations (<15% variation) provides a unique opportunity for SERS-based whole-organism fingerprinting. Egg prepared avian influenza virus and clinical sputum samples of human influenza virus were investigated to demonstrate SERS-based detection of a virus in a complex sample matrix and to assess the effect of different background matrices on the detection of similar viruses.

Differences in the capacity of two herpes simplex virus isolates to spread from eye to brain map to 1610 base pairs of DNA found in the gene for DNA polymerase.

A intertypic recombinant, designated HSV-R(D1), had previously been generated from non-neuroinvasive HSV-2(186) and neuroinvasive HSV-1(17). Although the recombinant contained < 2% of the HSV-1 genome, it retained the neuroinvasive phenotype. The nucleotide sequences responsible for the neuroinvasiveness of HSV-R(D1) were previously mapped to a 3.0 kb segment of DNA located within the DNA polymerase gene (mu 0.414 to 0.430) via marker rescue experiments. We have now sequenced this region and compared our results to the published nucleotide sequence of the HSV-1 (17) and HSV-2(186) DNA polymerase genes. It was found that the 3.0 kb HSV-R(D1) DNA fragment consisted entirely of HSV-2(186) nucleotide sequences except for the presence of 1610 bp of HSV-1 (17) DNA. The 1610 bp of HSV-1 DNA coded for a 536 amino acid (AA) region which were located between AA 254 and 790 of the DNA polymerase enzyme. Comparison of the 536 AA sequence of neuroinvasive HSV-1 (17) with the homologous area of the non-neuroinvasive HS...
Fertility preservation: state of the science and future research directions.

Objective To identify issues related to fertility preservation, discuss the state of the science, and make specific recommendations to guide future research supported by the U.S. National Institutes of Health in the field of fertility preservation. Design A 1-day meeting of an expert advisory panel convened by the Eunice Kennedy Shriver National Institute of Child Health and Human Development on January 23, 2007, at the National Institutes of Health in Bethesda, Maryland. The panelists represented the disciplines of reproductive endocrinology and infertility, urology, neurobiology, physiology, radiation oncology, pediatrics, genetics, behavioral science, surgery, and occupational health. Conclusion(s) The panel members recognized the emerging focus on fertility preservation to help women and men have biological children. Among those who might benefit from research in this area are those at risk for impaired fertility or infertility, including not only cancer survivors but also others with genetic predispositions to infertility, environmental occupational exposure to hazardous substances or conditions, or reproductive diseases such as endometriosis. The panelists highlighted the need for education and awareness among health-care providers to help people understand options for preserving fertility, the need for technologic advances, the lack of data on long-term consequences of fertility preservation, and emerging ethical and social questions. This report describes the process for developing a multidisciplinary, collaborative approach for research in this area, summarizes the discussions of the panelists, and outlines the recommendations for future research.

Near-field measurement of infrared coplanar strip transmission line attenuation and propagation constants

Impedance matched and low loss transmission lines are essential for optimal energy delivery through an integrated optical or plasmonic nanocircuit. A novel method for the measurement of the attenuation and propagation constants of an antenna-coupled coplanar strip (CPS) transmission line is demonstrated at 28.3 THz using scattering-type scanning near-field optical microscopy. Reflection of the propagating optical wave upon an open-circuit or short-circuit load at the terminal of the CPS provides a standing voltage wave, which is mapped through the associated surface-normal Ez electric near-field component at the metal-air interface. By fitting the analytical standing wave expression to the near-field data, the transmission line properties are determined. Full-wave models and measured results are presented and are in excellent agreement.
The nature of irrational beliefs in different personality clusters of spouse abusers

Previous research has shown that a majority of spouse abusers have personality characteristics which are consistent with personality disorder and show symptoms of depression and anger expression. Irrational beliefs have been associated with the same emotions in nonabuser populations. The current study assessed the nature of irrational beliefs in a sample of spouse abusers. The results showed that abusers with personality disorder held more irrational beliefs than abusers without personality disorder. Labile symptoms were associated with three categories of irrational beliefs only in the abusers with personality disorder. The implications for the characterization of spouse abusers and the modification of spouse abuse are discussed.
The value of regional lymph node dissection in genitourinary cancer

Regional lymph node dissection in the management of genitourinary (GU) neoplasms is controversial but is based on a 17 year clinical experience and the achievement of survival figures as good or better than those achieved by any other modality of therapy. Lymphadenectomy has proved to be effective in curing patients with metastatic testicular cancer, renal cell carcinoma and transitional cell carcinoma. Its efficacy in prostate cancer is much less certain and remains largely a staging procedure.

Proteomic analysis of mature melanosomes from the retinal pigmented epithelium.

The protein content of melanosomes in the retinal pigment epithelium (RPE) was analyzed by mass spectrometry. More than 100 proteins were found to be common to two out of three variations of sample preparation. Some proteins normally associated with other organelles were detected. Several lysosomal enzymes were detected, with the presence of cathepsin D confirmed by immunoelectron microscopy, thus supporting the previously suggested notion that melanosomes may contribute to the degradation of ingested photoreceptor outer segment disks. Keywords: retinal pigment epithelium • melanosome • proteomics
SU-E-T-09: Empirical Evidence for Decreased Cell Survival in Flattening Filter Free Beams.

Purpose: To present empirical evidence for a decrease in cell survival with the introduction of markedly increased average dose rates in flattening filter free beams. Methods: Data of (Bewes et al., 2008) are used to calculate a modification factor for cell survival curves, using the linear quadratic model, that is inversely proportional to the reciprocal of the average dose rate. Results: The survival curve becomes steeper as the average dose rate increases above a ∼600 cGy/min threshold. For average dose rates below this threshold, no significant effect or even an increase in cell survival was observed (as explained by the Lea‐Catcheside dose protraction factor). For a maximum assumed dose modification factor of 1.2 a decrease in cell survival of 3.5% for a dose of 2Gy and 36% for a dose of 8 Gy is predicted for a MM576 cell line. For a maximum assumed dose modification factor of 1.4 a decrease in cell survival of 60% for a dose of 2Gy and 1 order of magnitude for a dose of 8 Gy is predicted for a NCI‐H460 cell line. For a dose modification factor of 2.65 with a dose rate of 24 Gy/min, a decrease in cell survival of 1 order of magnitude at 2Gy and 5 orders of magnitude at 8 Gy is predicted for a NCI‐H460 cell line if it is assumed that the inverse proportionality is true. Conclusion: Although no effects on cell survival was seen previously with clinically achievable dose rates (except for enhanced cell survival through repair for increased treatment times), it might become more evident with the increase of the average dose rate in flattening filter free beams. This will necessitate revision of fractionation schemes and maximum tolerable doses for organs at risk for stereotactic body radiation therapy.
Raf-1 activates MAP kinase-kinase.

THE normal cellular homologue of the acutely transforming oncogene v-ra/is c-raf-l, which encodes a serine/threonine protein kinase that is activated by many extracellular stimuli1. The physiological substrates of the protein c-Raf-1 are unknown. The mitogen-activated protein (MAP) kinases ErkI and 2 are also activated by mitogens through phosphorylation of Erk tyrosine and threonine residues catalysed by a protein kinase of relative molecular mass 50,000, MAP kinase-kinase (MAPK-K)2–7. Here we report that MAPK-K as well as Erkl and 2 are constitutively active in v-raf-transformed cells. MAPK-K partially purified from v-raf-transformed cells or from mitogen-treated cells3 can be deactivated by phosphatase 2A. c-Raf-1 purified after mitogen stimulation can reactivate the phosphatase 2A-inactivated MAPK-K over 30-fold in vitro. c-Raf-1 reactivation of MAPK-K coincides with the selective phosphorylation at serine/threonine residues of a polypeptide with Mr 50,000 which coelutes precisely on cation-exchange chromatography with the MAPK-K activatable by c-Raf-1. These results indicate that c-Raf-1 is an immediate upstream activator of MAPK-K in vivo. To our knowledge, MAPK-K is the first physiological substrate of the c-raf-l protooncogene product to be identified.
Obtaining steady high-voltage direct current from a thermionic rectifier without a filter

The usual polyphase high-voltage rectifier produces a potential essentially constant out having superposed on it a "ripple" or alternating component whose amplitude on each side of the mean is from five to seven per cent of the total d-c. voltage. Condensers and reactors are used to filter the ripple out. The paper describes a special type of a-c. generator which will give the proper low-voltage wave form for rectification as a more nearly smooth direct potential. A method of manually or automatically varying the low-voltage wave form according to load demands is provided so as to keep the rectified potential steady, thus avoiding the necessity for the filter which in sets for 100,000 volts or more would be quite expensive and troublesome.

Comfort care: An alternative treatment programme for seriously burned patients

Abstract Modern intensive care is capable of keeping burned patients alive for substantial periods of time, despite burn severity with an ‘unprecedented’ or a marginal probability of survival. When the patient is initially judged to be that severely injured, or when, later in the course of the illness, a point is reached when further curative treatment is clearly futile (Civetta, 1981), the patient and/or the close relatives should be presented with the option of changing the treatment regimen from curative to comfort care. We (Frank and Wachtel, 1984) have described a process for reaching such decisions and a protocol for administering comfort care. During a 5-year period we offered this option to 24 patients. This paper reports the outcome in these cases.
Repositioning without Capitulation Discussions with June Nash on Identity, Activism and Politics

9 June Nash's work spans 50 years of anthropology and reflects important transformations in geopolitics, economic globalization, anthropological theory, and the people and societies we study. Nash's creativity reveals itself as inherently oppositional, even when she has written within major research paradigms. I argue that if we use the concept of 'repositioning' to examine the life work of an anthropologist, the notion of stable schools, paradigms and languages of analysis falls away to reveal a much more dynamic picture of anthropological practice. Based on interviews in 2002, this article examines the ways in which Nash has geographically and institutionally repositioned her ethnographic studies as an engaged anthropologist. It traces the ways her intellectual agenda and commitment to social justice have informed her research and ethnographic writing. The article is concerned with the living dimension of ethnographic knowledge, with Nash's fashioning of oral narratives that remember and reconsider her earlier fieldwork - as her published texts inevitably become historical artifacts. In the process, the article poses the question: how can we make ethnographic writing a more dynamic way of representing the human cost of the currents of change we seek to understand?
The Effect of Montelukast Sodium on the Duration of Effusion of Otitis Media

This study tests the hypothesis that montelukast sodium, a selective leukotriene receptor antagonist, will decrease the duration of the effusion of otitis media. Tympanometry and spectral gradient acoustic reflectometry were used to confirm the effusion of otitis media in patients between 2 and 12 years of age. Patients were treated with amoxicillin for 10 days and montelukast sodium or placebo for 30 days in a random, double-blind manner. Sixty patients completed the study: 31 received placebo and 29 received montelukast sodium. At a 4-week follow-up visit, 5 ears (16%) were free of effusion in the placebo group and 17 (58%) in the montelukast sodium group. The difference was significant. The efficacy of montelukast sodium in clearing the effusion was 49%.
Cholesterol utilization by Streptomyces spp.

Abstract Streptomyces spp . showed a much faster rate of cholesterol decomposition than any other species previously isolated and studied. Cholesterol served as a sole source of organic carbon for these streptomycetes. Apparently there are two points of primary attack on the cholesterol molecule and these attacks can occur either simultaneously or independently. This phenomenon appeared to be possible because in certain strains the enzymes which degraded one part of the cholesterol were inducible while others were constitutive.
Current Practices of Intimate Partner Violence Assessment Among Marriage and Family Therapy Trainees at a University Clinic

Research shows that the majority of couples presenting for couple therapy have experienced or are currently experiencing intimate partner violence (IPV) within their relationships. It is also known that few couples present for therapy with IPV as their main concern and seldom do couples spontaneously report IPV. A review of the literature that provides a rationale for the utilization of a universal screening process for IPV is provided. After which, the authors look at the current IPV assessment and screening practices of marriage and family therapists in a marriage and family therapy training facility. A logistic regression procedure was used to determine if an IPV assessment could be predicted based on risk factors of IPV from self-report intake information completed by participants. Unfortunately, only if clients actually indicated that physical violence within their relationship was a current issue were they assessed.
A Class of Quantile Measures for Kurtosis

Abstract Several authors have concluded that the standardized fourth central moment of a symmetric distribution is not a good measure of the shape of a distribution. Here we consider the properties of a class of parameters of a distribution based on its percentiles, as alternative measures of kurtosis. It is shown that this scale and location invariant measure maintains the symmetric ordering of van Zwet. Influence functions are used to show how this measure reflects the kurtosis of a distribution. Results of a simulation study indicate that the power of the Shapiro-Wilk test, for a large number of symmetric distributions alternative to the normal distribution, is almost linear as a function of appropriate functionals in this class. This suggests the use of this functional as a kurtosis measure.
Approach to the patient with hypertension, unexplained hypokalemia, and metabolic alkalosis

We present a patient with hypertension and hypokalemia secondary to an aldosterone-producing adenoma that was renin responsive (APARR). We discussed the sequential approach to the diagnosis of the different subtypes of primary aldosteronism and confirmed the presence of an APARR. The most common cause of primary aldosteronism is an aldosteronoma; functionally, these adenomas respond poorly to angiotensin II but show a brisk response to adrenocorticotropin hormone. They have a pattern of aldosterone level that declines in parallel with cortisol levels. Our patient had an APARR, with an increase of aldosterone in the upright posture. The unusual physiologic response, incidence, and clinical characteristics of APARR are reviewed.
Use of expert systems in the design of thermal equipment and processes

A study has been carried out on the use of knowledge-based computer-aided design methodology for the design of thermal systems. An expert system is developed using a Prolog-based front end, where the design rules, material databases, computational procedures, and the relevant expert knowledge are implemented. A combination of quantitative and heuristic inputs are employed in the design process. The basic approach employs an iterative redesign strategy, starting with an initial design obtained from the available knowledge base, and the design parameters are iteratively varied until the specified design rules and constraints are satisfied. The general approach can be employed for a variety of thermal systems. The application to a practical system is demonstrated by the design of an electrical furnace used in the thermal processing of materials. The results from the numerical simulation and design of this system are presented to indicate the basic features and the versatility of the expert system.
Atoms in Superstrong Magnetic Fields

It is pointed out that because of possibly large radiative corrections, the mass and magnetic moment of an electron in the presence of magnetic fields above ${10}^{13}$ G, which may be present in pulsars, are unknown. Calculations of ionization energies of atoms in such fields may therefore be meaningless unless the quantum-electrodynamic corrections are included.

For the first time, a near-infrared transmission spectroscopic method has been developed to directly determine the starch content in a liquid gravy model system at low starch concentration (less th...
Behavioural variation in natural populations. VI. Prey responses by two species of garter snakes in three regions of sympatry

Abstract Diets and congenital reactions to prey were studied in the garter snakes Thamnophis elegans and T. sirtalis at three sites where they occur in sympatry in northern California and Washington. Recently ingested prey retrieved from the stomachs of wild-caught snakes indicated that T. sirtalis was primarily an anuran predator at all three sites. In contrast, T. elegans was primarily a slug predator at two sites, but at a third site leeches, anurans and fish dominated the diet. Congenital reactions to prey were studied by measuring chemoreceptive responses to prey odours by naive, newborn snakes. Within each snake species, chemoreception scores showed litter differences within localities as well as geographical variation. Geographical differences in chemoreceptive responses generally coincided with geographical differences in diet, suggesting evolutionary responses to selection.
A new scheme for synchronization of inactive nodes in a sender-receiver protocol

This paper targets the problem of clock synchronization for a set of receivers lying within the broadcast range of two nodes implementing a general sender-receiver protocol using a wireless channel. The maximum likelihood estimate of the clock offset of the inactive node (and mean link delay) hearing the broadcasts from both the master and slave nodes was derived in [1] assuming symmetric exponential link delays. In this paper, the minimum variance unbiased estimate for the clock offset of such nodes is derived by applying the Rao-Blackwell-Lehmann-Scheffe theorem. The result is important in the realm of wireless sensor networks, where a tight network synchronization along with a conservative energy utilization plays a major role in network performance.
