Using Knowledge Processes to Improve Performance and Promote Change: The Continuous Loop Model and Cultural Enablers

This is a two part presentation. Part one introduces the continuous loop model (CLM) for improving firm performance. The CLM overlays tacit to explicit to tacit knowledge conversion processes with six sigma value stream processes, illustrating a management approach intended to accelerate the rate of knowledge creation focused on value-adding activities. Part two contributes to answering the question: What elements of organizational culture enable the CLM to work? Part two presents results from a research study investigating the cultural attributes needed to enable knowledge processes and the CLM to work effectively. Using the Great Place to Work® (GPTW) Institute lists of the 100 best companies to work for as a benchmark, financial data between 2004 and 2008 for matched pairs of companies were compared and evaluated. Cultural dimensions of the GPTW survey are credibility, respect, fairness (collectively, the Trust Index®), pride, and camaraderie. Results suggest that companies with perceived high levels of these cultural dimensions outperformed comparable firms in the same industry. Quantitative data supports the suggestion that elements of organizational culture, primarily trust, form the intangible link between knowledge processes and firm performance. The CLM strategies implemented in organizations with high levels of trust, pride, and camaraderie may enjoy superior results.
Emerging Family Therapy Models Utilized in Residential Settings

This chapter provides a synthesis of the research that is focused on family therapy interventions and outcomes in residential settings that treat adolescents. Although a significant amount of research has been conducted, there remains a significant gap since the research in residential treatment has been focused at the program level, and the field has not yet identified specific family therapy approaches that demonstrate efficacy in this particular setting. This chapter’s review focuses on the past ten years and will highlight the emerging family therapy models being utilized in this setting. The most prevalent models include multiple-family group intervention, family-directed structural therapy, narrative family therapy, and experiential therapy. The chapter will also include a discussion of three major well-established theoretical approaches that show promise in treating youth and families in the complex setting of residential treatment. These three approaches are brief strategic family therapy,multisystemic therapy, and functional family therapy. The chapter will conclude with a discussion of the strengths and limitations of conducting research in residential treatment, recommendations for clinicians working in this setting, and future directions for research.
Mild fetal cerebral ventriculomegaly: prevalence, characteristics, and utility of ancillary testing in cases presenting to a tertiary referral center

Objective Ventriculomegaly is the most common fetal brain anomaly identified during prenatal anatomy ultrasound. The aim of our study was to characterize cases of mild ventriculomegaly and investigate the utility of ancillary tests. Method We reviewed 121 cases of mild ventriculomegaly, defined as lateral ventricle diameter of 10 to 15 mm. Characteristics of the ventricular dilation as well as each pregnancy were investigated. Ancillary tests performed included follow-up magnetic resonance imaging (MRI), chromosomal abnormality testing, and maternal serologic infection screening. The utility of each test was analyzed. Results We identified 56 cases of isolated and 65 cases of complex ventriculomegaly. Seventy-two (59.5%) were unilateral, and 49 (40.5%) were bilateral, with a mean gestational age at diagnosis of 24.5 weeks. MRI provided additional information in 3/24 (12.5%) cases of isolated ventriculomegaly compared with 18/23 (78.2%) cases of complex ventriculomegaly. Chromosomal abnormality testing identified 4/9 (44.4%) genetic abnormalities compared with 8/30 (26.7%) in cases of isolated and complex mild ventriculomegaly, respectively. Finally, maternal serology infection screening was negative in all cases. Conclusion Ancillary testing is useful in isolated mild ventriculomegaly. Follow-up MRI and chromosome abnormality testing specifically provided clinically useful information. Although there were no cases of maternal infection, screening may be an important component in management. © 2017 John Wiley & Sons, Ltd.
Effect of moderate alterations of dietary protein or lysine on indices of lysine metabolism in liver, kidney, and heart of growing pigs1

Lysine addition to swine diets via either feed-grade lysine or protein sources costs producers. To better understand how diet affects lysine oxidation (LOX), weanling pigs were fed a control (C), high protein (HP), low protein (LP), high lysine (HL), or low lysine (LL) diets. No diet-induced alterations in lysine catabolism were detected in heart or kidney (P > 0.05). Liver lysine α-ketoglutarate reductase (LKR) (P < 0.05), saccharopine dehydrogenase (P < 0.05) activities, and α-aminoadipate δ-semialdehyde synthase abundance (P < 0.01) were reduced by 30%, 35%, and 52%, respectively, in pigs consuming LL compared with pigs consuming C. Expression of ornithine carrier-1 (ORC-1) mRNA in pigs fed HL was 170% greater (P < 0.05) than that in pigs fed C, whereas expression of the ORC-1 mRNA in pigs fed LL was 50% lower (P < 0.05) than that in pigs fed C. Expression of ORC-2 mRNA in pigs fed HL was 88% higher (P < 0.05) than that in pigs fed LL. The ORC transporters and LKR phosphorylation are likely points of r...
The quadruple burden of sepsis.

KEY POINTS Over 2000 years ago, Hippocrates introduced the term σψιής (sipsi), which loosely translates to “make rotten.” Subsequent health practitioners observed an association between “blood putrefaction” and fever, and around 150 years ago, Louis Pasteur linked putrefaction to tiny
Landscape Factors Associated with Subterranean Termite (Isoptera: Rhinotermitidae) Treatments and Colony Structure in Residential Subdivisions

Subterranean termites (Isoptera: Reticulitermes ) are common structural pests, but it is not well known how landscape factors are associated with urban colonization. This study examined patterns of subterranean termite colonization in 13 mid-Missouri residential subdivisions. Ten- and 20-year-old homes built on historically agricultural and forested landscapes were inspected for treatment by termiticide application or bait stations. Contemporary and historical aerial imagery were analyzed using GIS software, and patterns of colonization were compared among subdivisions. The genetic structure of termite colonies collected in undeveloped landscapes and residential subdivisions was compared using microsatellite DNA. Twenty-year-old subdivisions had significantly higher treatment proportions than 10-year-old subdivisions. At year 10, historically forested subdivisions had a higher treatment proportion than historically agricultural subdivisions. By year 20, there was no significant difference in treatment proportion between historical landscape types, indicating that subdivisions built on agricultural landscapes eventually catch up to subdivisions built on forest landscapes. Although there was not strong statistical support, treated homes in historically agricultural subdivisions tended to be close to forest patches, but there was less of an association in historically forested subdivisions. Colonies in undeveloped landscapes were more inbred compared to colonies in residential subdivisions, indicating that colonies sampled in subdivisions had fewer secondary reproductive and were potentially younger than those sampled in undeveloped landscapes. This study provides some correlative support for the role of dispersing alates as urban colonizers, because treatments were often located at relatively long distances from undisturbed forest patches in historically agricultural subdivisions.
Inheritance and Health: What Really Matters?

The author calls for public health professionals and advocates to inform politicians, policymakers, and other scientists on why disease prevention cannot be achieved through a focus on genomes and biological inheritance. Citing the work of pharmacologist Wilhelm Johannsen, the author argues that societal inheritance is a bigger factor and emphasizes contextualized phenotypes over decontextualized genomes.
A comparison of the acoustic vowel spaces of speech and song

Speaking and singing are two modes of the same system. These modes are subject to similar constraints, but have different goals. This study examined the acoustic vowel spaces, as defined by formant frequencies, used by singers when they were singing or speaking the same linguistic content. Overall, formant values decreased during singing compared to singing. This resulted in compression of the vowel space, with more overlapping vowel regions during singing. However, this was not consistent for all vowels and all singers. Differences between the modes are partially explained by known articulatory processes used during singing, such as larynx lowering. This may reflect the way that speakers balance communicative versus aesthetic concerns when articulating lyrics. (The Pennsylvania State University Brandywine)
Predicting Outcomes Following Resuscitation

Outcomes of pediatric resuscitation depend on the location, pre-arrest and arrest variables including quality of CPR. Out-of-hospital cardiac arrest has poorer survival and neurological outcomes due to the longer period of no-flow time, as well as the underlying etiologies of out-of-hospital cardiac arrest that are themselves associated with poor outcomes (e.g. Sudden Infant Death Syndrome or drowning). In contrast, more than 90 % of in-hospital pediatric cardiac arrests are witnessed or monitored, and CPR is provided. Half of in-hospital pediatric cardiac arrest victims are successfully resuscitated to return of spontaneous circulation and a quarter will survive to discharge. Sixty-five percent of survived children had favorable neurological outcomes. Pre-arrest and arrest variables are highly associated with survival and neurological outcomes. However, these pre-arrest and arrest variables tend to have a high false positive rate for predicting poor neurological outcomes. There are no reliable predictors of outcome in children. High quality of CPR is associated with short term survival outcomes. For post-arrest variables, absence of pupillary exams after 48 h is predictive for poor neurological outcome when therapeutic hypothermia is not induced. EEG finding with mild slowing and rapid improvement are associated with good outcomes, while burst suppression, electrocerebral silence, and lack of reactivity are associated with poor outcome. Somatosensory evoked potentials (SSEPs) are much less influenced by drugs, and resistant to environmental noise artifacts in contrast to bedside EEG. Bilateral absence of the N20 components in SSEPs is consistently associated with poor neurological outcomes. Serum neuron-specific enolase (NSE) and S-100B protein have been evaluated as prognostic indicators. NSE had higher discriminative ability for poor neurological outcomes compared to S100-B protein. For patients receiving therapeutic hypothermia, absence or extensor motor responses after achievement of normothermia is predictive for poor neurological outcomes. Neurological finding during therapeutic hypothermia is not reliable.
Molecular imaging of epidermal growth factor-receptor and survivin in vivo in porcine esophageal and gastric mucosae using probe-based confocal laser-induced endomicroscopy: proof of concept.

Author(s): Nakai, Y; Shinoura, S; Ahluwalia, A; Tarnawski, A S; Chang, K J | Abstract: Confocal laser-induced endomicroscopy (CLE) enables in vivo, real time visualization of the subsurface cells and tissue structures in gastrointestinal mucosa at a subcellular resolution of ≈1000x magnification. The aims of this pilot study were to establish a principle of molecular imaging and determine in vivo expression of epidermal growth factor receptor (EGF-R) and survivin in porcine esophageal and gastric mucosa using probe-based CLE (pCLE) and topically applied FITC-labeled antibodies. Studies were performed in anesthetized pigs. During endoscopy FITC-labeled antibodies against EGF-R and survivin were either sprayed onto esophageal and gastric mucosa in preselected areas or administered via submucosal injection. Thirty minutes later pCLE was performed using a through-the-scope probe (GastroFlex UHD, Cellvizio, Mauna Kea Technologies, Paris, France) to determine cellular and tissue localization of EGF-R and survivin. Then the pigs were euthanized and esophageal and gastric walls from the areas sprayed or injected with antibodies were collected for histologic examination under epifluorescence microscopy.CLE enabled visualization of EGF-R and survivin in esophageal and gastric mucosa and this was confirmed by histology. In the esophagus both EGF-R and survivin were localized predominantly to the keratinocyte progenitor cells. In the stomach, EGF-R was localized to progenitor zone cells and some epithelial cells. Localization of survivin was similar, but involved more surface epithelial cells. This study demonstrated feasibility of using CLE and topical administration of FITC labeled antibodies for in vivo localization of EGF-R and survivin in esophageal and gastric mucosa.
Radius of influence of air temperature from automated weather stations installed in complex terrain

Air temperature measured by automated weather stations is used by growers and other stakeholders to inform their decisions that are affected by local weather conditions. Although modern systems record and transmit weather information remotely at regular time intervals, the spatial resolution of the data is unknown. This study aimed to determine the radius of influence (RI) of daily air temperature and to analyze the dynamic response of RI. An analysis based on the similarity between data recorded at two weather stations as a function of their distance was conducted using daily air temperature data for 158 weather stations in the Pacific Northwest (PNW). The results showed that the mean RI for minimum temperature (20 km) was significantly different from the RI calculated for maximum temperature (23 km). There was also both high spatial and temporal variability. We found that the landscape and season of the year were crucial factors that define the RI of air temperature recorded for a particular location. In flat regions, the RI was greater than in areas where the elevation varied over a short distance, and the RI was smaller during the summer than during any of the other seasons. The results showed that for complex terrain it is not possible to define a general RI for daily air temperature.

Halogen Bonding Interactions for Aromatic and Nonaromatic Explosive Detection

Improved sensing strategies are needed for facile, accurate, and rapid detection of aromatic and nonaromatic explosives. Density functional theory was used to evaluate the relative binding interaction energies between halogen-containing sensor model molecules and nitro-containing explosives. Interaction energies ranged from -18 to -14 kJ/mol and highly directional halogen bonding interactions were observed with bond distances ranging between 3.0 and 3.4 A. In all geometry optimized structures, the sigma-hole of electropositive potential on the halogen aligned with a lone pair of electrons on the nitro-moiety of the explosive. The computational results predict that the strongest interactions will occur with iodine-based sensors as, of all the halogens studied, iodine is the largest, most polarizable halogen with the smallest electronegativity. Based on these promising proof-of-concept results, synthetically accessible sensors were designed using 1,4-dihalobenzene (X = Cl, Br, and I) with and without tetra-fluoro electron withdrawing groups attached to the benzene ring. These sensing molecules were embedded onto single walled carbon nanotubes that were mechanically abraded onto interdigitated array electrodes, and these were used to measure the responses to explosive model compounds cyclohexanone and dimethyl-dinitro-benzene in nitrogen gas. Amperometric current-time curves for selectors and control molecules, including concentration correlated signal enhancement, as well as response and recovery times, indicate selector responsiveness to these model compounds, with the largest response observed for iodo-substituted sensors.
Reactive Oxygen and Nitrogen Species in the Oral Cavity

In the oral cavity, reactive oxygen and nitrogen species are continuously generated by bacterial metabolism and host-mediated cellular factors. These reactive species facilitate a critical function that regulates the outcomes of both oral and systemic diseases, such as dental caries, periodontitis, and the maintenance of blood pressure. As a result, the protective effects of ROS and RNS are being explored for future therapeutic applications.
Legacies of Love, Peace and Hope: How Bioethics Education can Overcome Hatred and Divide

In our pursuit of a good life (eubios), both individuals and societies, need to educate themselves on the pursuit of love of life in all domains, self-love, love of others, loving good and love of life. In this paper I reflect on my own journey through growing up in Christchurch, and experiences around the world, that are the basis for that conclusion. In our efforts to pursuit bioethics education we can enhance peaceful and harmonius coexistence in our world, through nurturing good decisions that we should all make.
Internet Appendix for State-Varying Factor Models of Large Dimensions

The Internet Appendix collects the proofs and additional results that support the main text. The additional theoretical results include a detailed description of special cases and related models and an extension to noisy and misspecified state processes. We also provide an estimator for the number of factors. The additional empirical results consider alternative state processes and discuss the choice of tuning parameters. We also study a portfolio application of our state-varying factors. The extensive simulation section compares the performance relative to alternative latent factor models that allow for time-variation and studies the choice of bandwidth and number of factors with cross-validation arguments. Lastly, we collect the detailed proofs for all the theoretical statements.

Modeling the Growth and Spread of Infectious Diseases to Teach Computational Thinking

Modeling is commonly employed in school settings to help students develop an understanding of biological systems [3]. By inspecting and modifying the inner workings of their models, students become familiar with causal factors and how they impact the properties of the model. We believe that allowing students to tinker with computational models involves developing the same skills used in computational thinking, such as abstraction, decomposition, analysis, automation, and generalization. In this poster, we discuss the design and implementation of a simulation that models the growth and spread of a hypothetical disease. The goal is to help middle school students develop computational thinking skills while learning how a virus spreads through the human population.
Dietary Insights in Neurological Diseases.

Dietary interventions may play a role in the pathophysiology of common neurological disorders such as Alzheimer’s disease, Parkinson’s disease, stroke, migraines, multiple sclerosis, and epilepsy. This article describes the most common and impactful dietary regimens for commonly encountered neurological disorders. Plant-based, low-fat, high-fiber diets, rich in antioxidants and other lifestyle interventions may reduce the burden and disability of common neurological disorders. The ketogenic diet, the diet of choice for the treatment of refractory epilepsy, is such an example. Diverse neurological disorders demonstrate several common pathophysiological mechanisms including increased oxidative stress, neuroinflammation, and disrupted metabolism. Dietary interventions can potentially influence these pathophysiological processes and thus favorably alter clinical outcomes. Adequate dietary choices should be considered as part of a continuum of healthy lifestyle choices.
Influence of the Contact Surface Size on the Illusory Movement Induced by Tendon Vibrations.

In human limbs, tendon vibration evokes the feeling of illusory movement, which is a kinesthetic sensation experienced in the absence of any actual joint movement. This phenomenon can be effectively used to generate kinesthetic sensation in virtual-reality settings, which can solve a variety of problems. However, its implementation remains limited due to the hitherto-unclear relationship between stimulus and perceptual characteristics. This study is aimed at examining the effects of the size of contact surfaces on the illusory kinesthetics evoked by tendon vibration. Tendons of the biceps brachii in the dominant-side arm of five participants were stimulated for 30 s at 100 Hz and 120 m/s2 by a vibration device. Contact heads of different sizes (φ5, φ10, φ15, and φ20 mm) were tested on subjects. The shoulder was held stationary on an armrest at a flexion of 90° while the elbow was flexed at 0°—both in the midsagittal plane, with palms facing upwards. After the experiment, participants were asked to take two subjective evaluations based on the visual analog scale, pertaining to the vividness (1: weak, 5: clear) and range of extension of their elbow-joint angle (1: slight, 5: significant). During the illusory motion, both these parameters increased with the size of the contact surface. Thus, we concluded the perceptual characteristics of the illusory movement to be affected by the size of the contact surface.
With or Without You? Contextualizing the Impact of Romantic Relationship Breakup on Crime Among Serious Adolescent Offenders.

The decline and delay of marriage has prolonged adolescence and the transition to adulthood, and consequently fostered greater romantic relationship fluidity during a stage of the life course that is pivotal for both development and offending. Yet, despite a growing literature of the consequences of romantic relationships breakup, little is known about its connection with crime, especially among youth enmeshed in the criminal justice system. This article addresses this gap by examining the effects of relationship breakup on crime among justice-involved youth—a key policy-relevant group. We refer to data from the Pathways to Desistance Study, a longitudinal study of 1354 (14 % female) adjudicated youth from the juvenile and adult court systems in Phoenix and Philadelphia, to assess the nature and complexity of this association. In general, our results support prior evidence of breakup’s criminogenic influence. Specifically, they suggest that relationship breakup’s effect on crime is particularly acute among this at-risk sample, contingent upon post-breakup relationship transitions, and more pronounced for relationships that involve cohabitation. Our results also extend prior work by demonstrating that breakup is attenuated by changes in psychosocial characteristics and peer associations/exposure. We close with a discussion of our findings, their policy implications, and what they mean for research on relationships and crime among serious adolescent offenders moving forward.
SOLAR IRRADIANCE AND DROUGHT STRESS EFFECTS ON THE ACTIVITY AND CONCENTRATION OF RIBULOSE BISPHOSPHATE CARBOXYLASE IN ‘VALENCIA’ ORANGE LEAVES

ABSTRACT The activities of HCO3 −/Mg2+-activated ribulose bisphosphate carboxylase (RuBPCase) in leaves from unstressed and drought-stressed ‘Valencia’ orange (Citrus sinensis [L.] Osbeck) trees were higher by 45% and 17%, respectively, at midmorning than at predawn and remained relatively unchanged for several hours during the day. The level of nonactivated RuBPCase in unstressed trees increased similarly at mid- morning (by 45%), but dropped back to the predawn value at midday and in the afternoon. In drought-stressed trees, however, the level of nonactivated RuBPCase decreased by 31% at midmoming. Within a 24-h diel cycle, the drought-stress- induced decreases in RuBPCase activities averaged 31% for the activated enzyme and 22% for the nonactivated one. During this 24-h experimental period, the values of RuBPCase and soluble protein in stressed leaves averaged 70% and 77%, respectively, of those recorded in control leaves. Thus, in ‘Valencia’ orange trees, a reduction in RuBPCase activity and concentra...
The Corporate Census: A Preliminary Exploration

Professor Conard has provided a much needed article in which he critically examines some of the preconceived notions that have distorted legal thinking about corporations. The author examines the asset size distribution of corporations; the number of corporations, partnerships, and proprietorships as a function of asset size; and the distribution of corporations by number of shareholders. His data indicate that while there is no "typical" corporation, the overwhelming majority of corporations are closely held with assets under a million dollars. This result emphasizes the need for careful legislative drafting in corporate, tax and securities legislation to reflect the different characteristics of the variety of corporate enterprises.

Contrast-Invariant Registration of Cardiac and Renal MR Perfusion Images

Automatic registration of dynamic MR perfusion images is a challenging task due to the rapid changes of the image contrast caused by the wash-in and wash-out of the contrast agent. In this paper we introduce a contrast-invariant similarity metric and propose a common framework to perform affine registration on both cardiac and renal MR perfusion images. First, large-scale translational motion is identified by tracking a selected region of interest with integer pixel shifts. Then, we estimate the affine transformation of the organ for each frame. We have tested the proposed algorithm on real cardiac and renal MR perfusion scans and obtained encouraging registration results.
Effects of prolonged sleep deprivation on local rates of cerebral energy metabolism in freely moving rats

Although sleep deprivation interferes with biological processes essential for performance, health, and longevity, previous studies have failed to reveal any structural or functional changes in brain. We have therefore measured local rates of cerebral glucose utilization (ICMRglc) with the quantitative autoradiographic 2–14C-deoxyglucose method in an effort to determine if and, if so, where sleep deprivation might affect function in sleep-deprived rats. Sleep deprivation was maintained for 11–12 d, long enough to increase whole body energy metabolism, thus confirming that pathophysiological processes that might involve brain functions were evolving. Deep brain temperature was also measured in similarly treated rats and found to be mildly elevated relative to core body temperature. Despite the increased deep brain temperature, systemic hypermetabolism, and sympathetic activation, ICMRglc was not elevated in any of the 60 brain structures examined. Average glucose utilization in the brain as a whole was unchanged in the sleep-deprived rats, but regional decreases were found. The most marked decreases in ICMRglc were in regions of the hypothalamus, thalamus, and limbic system. Mesencephalic and pontine regions were relatively unaffected except for the central gray area. The medulla was entirely normal. The effects of sleep deprivation on brain tended, therefore, to be unidirectional toward decreased energy metabolism, primarily in regions associated with mechanisms of thermoregulation, endocrine regulation, and sleep. Correspondence was found between the hypometabolic brain regions and some aspects of peripheral symptoms.

Regional Radio: A Response by the Ghana Broadcasting Corporation to Democratization and Competition

Abstract: In 1992, constitutional governance was re-established in Ghana, and private broadcasting made legal for the first time. This paper explores one of the responses of the state-owned Ghana Broadcasting Corporation (GBC) to this novel situation, the opening of regional FM radio stations. Primary data for the paper was obtained from visits to six of the stations and interviews with station directors and other staff in July 1998. The political economic context in which the stations were established, their structures, and programming are examined. Evidence from this study indicates that with the new stations the GBC is expanding and enhancing its public service mandate. At the same time, institutional structures and scarce financial resources combine to prevent the Corporation from becoming independent of vested interests: government, commerce, or NGOs. Resume: En 1992, on retablit un gouvernement constitutionnel au Ghana et on legalisa la radiodiffusion privee pour la premiere fois dans ce pays. Cet article explore une des reponses a cette nouvelle situation de la part du radiodiffuseur d'etat, le Ghana Broadcasting Corporation (GBC) : l'ouverture de stations de radio FM regionales. Les donnees de cet article furent recueillies lors de visites de six de ces stations en juillet 1998 et d'entrevues avec les directeurs des stations et d'autres membres du personnel. L'article examine le contexte politico-economique de la creation, la structure et la programmation de ces stations. Les donnees recueillies pour cette etude indiquent que, grâce aux nouvelles stations, le GBC est en train de prendre de l'extension et de mieux remplir son mandat de service public. En meme temps, cependant, les structures institutionnelles et les ressources financieres peu abondantes de la Corporation empechent celle-ci de gagner son independance par rapport a certains organismes interesses : le gouvernement, les entreprises et les associations a but non lucratif.
Cardinalities in the projective hierarchy

We show that the “effective cardinality” of the collection of sets is strictly bigger than the effective cardinality of the . The phrase effective cardinality is vague but can be made exact in the usual ways. For instance:Theorem 1.1. Assume ADL(ℝ)Then in L(ℝ) there is no injection.A few years ago Tony Martin showed a similar result, establishing the non-existence of an injection from to for m sufficiently larger than n. His method did not seem to work for m = n + 1.This present paper gives level by level calculations for the projective hierarchy, but it too falls short of a complete analysis, in as much as it leaves the position of the effective cardinals in the Wadge degrees largely obscure. At the low levels it takes some time for any new cardinals to appear. Whenever Γ1, Γ2 are non-trivial Wadge degrees strictly included in one has.
High altitude adaptation and anaerobiosis in sceloporine lizards.

Abstract o 1. The duration of maximal activity and the intensity of anaerobic metabolism were measured in lowland Sceloporus occidentalis at low (200 ft) and high (10,150 ft) elevations and compared to those of resident S. occidentalis and S. graciosus at high altitude. 2. The duration of maximal activity is independent of altitude: all groups of S. occidentalis had the same stamina, regardless of the altitude of experimental or prior residence. 3. The amount of lactate formed during activity is also independent of altitude or prior resisence. 4. No indications of altitude adaptation were found in these species. It is hypothesized that the basically anaerobic activity patterns of small lizards constitute a preadaptation to colonization of high altitudes.
Corrigendum to “School choice: An experimental study” [J. Econ. Theory 127 (1) (2006) 202–231]☆

Abstract We correct an inconsistency in the efficiency comparison reported in [Y. Chen, T. Sonmez, School choice: An experimental study, J. Econ. Theory 127 (1) (2006) 202–231]. The efficiency comparison of the three school choice mechanisms in our paper is based on recombinant estimation with an identical set of 10 tie-breakers, while the statistics reported in Table 7 is computed using 14,400 tie-breakers.
Enterprise HPC storage systems

High performance compute systems place an increasing demand on the their primary connected storage systems. Modern filesystem implementations are no longer just for “scratch” only, data availability and data integrity are considered just as important as performance. In today's market place as well as in advanced research, the demands on a storage system increase along a number of fronts including capacity, data integrity, system reliability, and system manageability, in addition to an ever-increasing need for performance. Understanding the tuning parameters available, the enhancements in RAID reliability as well as possible tradeoffs between slightly opposing tuning models becomes a critical skill. The Lustre filesystem has for many years been the most popular distributed filesystem for HPC. While the Lustre community to date has been partial to older Lustre server and client releases, a number of the new features desired by many users, requires moving to more modern versions. The major dilemma historically has been that client versions such as 1.8.× perform faster than the 2.× releases, but support for modern Linux kernels is only available with recent Lustre server releases, and newly-implemented feature sets requires moving to newer client versions. This paper examines the client and server tuning models, security features and the advent of new RAID schemes along with their implications for performance. Specifically, when using benchmarking tools such as IOR, new testing models and parameter sets requires storage I/O benchmarking to change and more closely mimic contemporary application I/O workloads.

Scapholunate dissociation: A practical approach for the emergency physician

Scapholunate dissociation is an injury caused by forced hyperextension of the wrist and results in characteristic radiographic features that may not be apparent on routine x-ray studies. In addition, significant ligamentous damage may be present even with normal radiographs. If misdiagnosed and improperly treated, this injury can lead to chronic wrist pain, instability, and degenerative changes. We present an illustrative case, review the pertinent literature, and present an algorithm for the evaluation and management of scapholunate dissociation.
NHE3 activity is dependent on direct phosphoinositide binding at the N terminus of its intracellular cytosolic region.

The small intestinal BB Na+/H+ antiporter NHE3 accounts for the majority of intestinal sodium and water absorption. It is highly regulated with both postprandial inhibition and stimulation sequentially occurring. Phosphatidylinositide 4,5-bisphosphate (PI(4,5)P2) and phosphatidylinositide 3,4,5-trisphosphate (PI(3,4,5)P3) binding is involved with regulation of multiple transporters. We tested the hypothesis that phosphoinositides bind NHE3 under basal conditions and are necessary for its acute regulation. His6 proteins were made from the NHE3 C-terminal region divided into four parts as follows: F1 (amino acids 475–589), F2 (amino acids 590–667), F3 (amino acids 668–747), and F4 (amino acids 748–832) and purified by a nickel column. Mutations were made in the F1 region of NHE3 and cloned in pet30a and pcDNA3.1 vectors. PI(4,5)P2 and PI(3,4,5)P3 bound only to the NHE3 F1 fusion protein (amino acids 475–589) on liposomal pulldown assays. Mutations were made in the putative lipid binding region of the F1 domain and studied for alterations in lipid binding and Na+/H+ exchange as follows: Y501A/R503A/K505A; F509A/R511A/R512A; R511L/R512L; R520/FR527F; and R551L/R552L. Our results indicate the following. 1) The F1 domain of the NHE3 C terminus has phosphoinositide binding regions. 2) Mutations of these regions alter PI(4,5)P2 and PI(3,4,5)P3 binding and basal NHE3 activity. 3) The magnitude of serum stimulation of NHE3 correlates with PI(4,5)P2 and PI(3,4,5)P3 binding of NHE3. 4) Wortmannin inhibition of PI3K did not correlate with PI(4,5)P2 or PI(3,4,5)P3 binding of NHE3. Two functionally distinct phosphoinositide binding regions (Tyr501–Arg512 and Arg520–Arg552) are present in the NHE3 F1 domain; both regions are important for serum stimulation, but they display differences in phosphoinositide binding, and the latter but not the former alters NHE3 surface expression.

Working Capital Requirements Revisited

ABSTRACT The conventional approach to considering working capital cash flows in capital budgeting is to omit them or include some ad hoc figures at the initiation and termination of the project. The authors argue for an endogenous system of estimating relevant working capital cash flows on a periodic basis. Otherwise, the present value of working capital cash flows is biased against the project's acceptance. Examples of calculating working capital cash flows as related to changes in annual sales are presented for three time patterns of sales and contrasted to the conventional method. An empirical study of the linear relationship of net working capital and sales revenue of 770 companies is reported, and an alternative cash flow model is offered thai includes working capilal cash flows.
Finite Extensions and the Number of Countable Models

An Ehrenfeucht theory is a complete first order theory with exactly n countable models up to isomorphism, 1 ω . Numerous results have emerged regarding these theories ([1]–[15]). A general question in model theory is whether or not the number of countable models of a complete theory can be different than the number of countable models of a complete consistent extension of the theory by finitely many constant symbols. Examples are known of Ehrenfeucht theories that have complete extensions by finitely many constant symbols such that the extensions fail to be Ehrenfeucht ([4], [8], [13]). These examples are easily modified to allow finite increases in the number of countable models. This paper contains examples in the other direction—complete theories that have consistent extensions by finitely many constant symbols such that the extensions have fewer countable models. This answers affirmatively a question raised by, among others, Peretyat'kin [8]. The first example will be an Ehrenfeucht theory with exactly four countable models with an extension by a constant symbol that has only three countable models. The second example will be a complete theory that is not Ehrenfeucht, but which has an extension by a constant symbol that is Ehrenfeucht. The notational conventions for this paper are standard. Peretyat'kin introduced the theory of a dense binary branching tree with a meet operator [7]. Dense ω -branching trees have also proven useful [5], [11]. Both of the Theories that will be constructed make use of dense ω -branching trees.
First-principles study of electronic structure, defects, and activators in LiCaAlF6

ABSTRACT LiCaAlF 6 (LiCAF) is a promising inorganic neutron scintillator mate rial. Here, we report the electronic structure as well as properties of the small hole polaron, F center, and activators (e.g., Ce) in LiCA F based on first-principles calculations. These results are discussed in the context of carrier transpor t and trapping in LiCAF. We also discuss the approach to reduce reabsorption of Ce emission by the F centers, thereby suppressing afterglow in LiCAF:Ce after exposure to X- or gamma-ray. Keywords: LiCaAlF6, neutron detection, scintillator, electronic structure, defects, F center 1. INTRODUCTION LiCaAlF 6 (LiCAF) has been traditionally investigated as a leadin g candidate for solid-state lasers in the UV region. 1, 2, 3, 4 More recently though, LiCAF has also a ttracted considerable interest as a pr omising scintillator material for neutron detection. 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 LiCAF contains 6 Li, which has a large thermal neutron cross-section for the
My Body Lies Over the Keyboard: Agency and Efficacy in Weblog Storytelling

A series of imaginary weblog entries explores the bodily capability for storytelling in weblogs. Weblog storytelling embraces or brings together both stories and tellings. Thinking and speaking in stories is efficacious for learning what it is we want to say (the bodily capability to narrate a story, to produce the desired effect) and, at the same time, the very practice of telling stories constitutes and inscribes us as agents in power relations (the bodily capability to function as addressee and addresser: both inside the story as narrator and character, and outside the story as listener and teller). In storytelling, the weblog writer and reader “lie over the keyboard,” that is, they are caught up in a system of equivalences that transforms perception into expression and one gesture into another. Weblog storytelling relies on the agency and efficacy of bodily participation by which we respond not to the virtual but to the imaginary texture of the real.
Improved detection of echocardiographic left ventricular hypertrophy using a new electrocardiographic algorithm

Abstract Objectives. The purpose of this study was to use the Framingham data base to devise and test an improvement in an electrocardiographic (ECG) voltage criterion for detecting left ventricular hypertrophy that is gender specific and adjusts for age and obesity. Background. Electrocardiographic detection of left ventricular hypertrophy has been receiving increasing attention. The “Cornell” ECG voltage, defined as the sum of voltages for the R wave of lead aVL and the S wave of lead V3, has been shown to correlate strongly with echocardiographically estimated left ventricular mass. Because the magnitude of this voltage varies with both age and obesity, we have proposed a simple formula for its adjustment for these two variables. Methods. Using linear regression, the adjustment formula was estimated from data on 1,468 men and 1,883 women from the Framingham Heart Study cohort who were free of myocardial infarction and who had both an ECG and an echocardiogram recorded during the same clinic examination. A modified receiver operating characteristic curve method was used to compare sensitivities at the same specificity levels. The adjustment formula was estimated from one randomly chosen half of the study cohort and applied to the other half for evaluation. Results. Significant improvement in sensitivity for the detection of left ventricular hypertrophy was realized at all levels of specificity. At a specificity level of 98%, the adjustment increased the sensitivity of the Cornell voltage from 10% to 17% in men and from 12% to 22% in women. For severe hypertrophy, defined as a left ventricular mass >3 SD above the gender-specific mean, the sensitivity increased from 23% to 38% for men and from 22% to 55% for women at a specificity level of 95%. Conclusions. This approach can substantially enhance the utility of the ECG for the detection of left ventricular hypertrophy. If these results are validated in other population groups, this approach may prove valuable in the screening of hypertensive populations and for the monitoring of patients undergoing treatment for hypertension.
Dominant superconducting fluctuations in the one-dimensional extended Holstein-extended Hubbard model

The search for realistic one-dimensional (1D) models that exhibit dominant superconducting (SC) fluctuations effects has a long history. In these 1D systems, the effects of commensurate band fillings---strongest at half-filling---and electronic repulsions typically lead to a finite charge gap and the favoring of insulating density wave ordering over superconductivity. Accordingly, recent proposals suggesting a gapless metallic state in the Holstein-Hubbard (HH) model, possibly superconducting, have generated considerable interest and controversy, with the most recent work demonstrating that the putative dominant superconducting state likely does not exist. In this paper we study a model with nonlocal electron-phonon interactions, in addition to electron-electron interactions. This model unambiguously possesses dominant superconducting fluctuations at half filling in a large region of parameter space. Using both the numerical multi-scale functional renormalization group (MFRG) for the full model and an analytic conventional renormalization group for a bosonized version of the model, we demonstrate the existence of these dominant SC fluctuations and show that they arise because the spin-charge coupling at high energies is weakened by the nonlocal electron-phonon interaction and the charge gap is destroyed by the resultant suppression of the Umklapp process. The existence of the dominant SC pairing instability in this half-filled 1D system suggests that nonlocal boson-mediated interactions may be important in the superconductivity observed in the organic superconductors.
Covert and Overt Dependence in Suicidal Women and Their Male Partners

Dependence has traditionally been associated with suicidal behavior, especially in women. According to recent psychodynamic formulations, overt expression of dependence is influenced by covert mental representations and context-interactional variables. This study explored the covert mental representations and the interactional context of dependence in suicidal women and their male nonsuicidal partners. On the basis of theory, we hypothesized that suicidal women and their partners would have similar covert dependent needs, but opposite styles of dealing with these needs. The suicidal women would express these needs directly through overt dependent behavior while their partners would manifest their dependent needs indirectly through reinforcing dependent behavior in suicidal women. As predicted by theory, suicidal women and their partners were found to be similar in terms of covert dependence and different with regard to overt behavior—male partners tending to foster dependence in suicidal women.
