Developing Global Business Capabilities in MBA Students

The need to develop global business capabilities in MBAs is clear and growing, and faculty must create efficient and effective processes for developing these capabilities.The author offers for consideration an approach that utilizes theory combined with practice to begin developing global business capabilities during a one-semester course. The five global mind-sets (reflective, analytical, worldly, collaborative, and action) offered by Mintzberg provide a useful framework for categorizing the desired learning. He demonstrates that by using a variety of complementary approaches, including case analyses in multicultural teams, local and foreign business-opportunity analyses, a business-venture proposal that bridges two countries, and a focused study tour, students can make real progress in learning the five mind-sets. Pre—post questionnaires and qualitative data support the conclusion that MBAs who participate in an organized and diverse learning experience can begin to develop global business capabilities ...
Walking a high beam: the balance between employment stability, workplace flexibility, and nonresident father involvement.

Compared with resident fathers, nonresident fathers are more likely to be unemployed or underemployed and less likely, when they are employed, to have access to flexible work arrangements. Although lack of employment stability is associated with lower levels of father involvement, some research shows that increased stability at work without increased flexibility is negatively related to involvement. Using data from the Fragile Families and Child Wellbeing Study (N = 895), the authors examined the relationship between nonresident fathers’ employment stability, workplace flexibility, and father involvement. Results indicate that workplace flexibility, but not employment stability, is associated with higher levels of involvement. Policy and practice implications are discussed.
Hurt Feelings among New Acquaintances: Moderating Effects of Interpersonal Familiarity

Previous research suggests that people's feelings are hurt more frequently by those whom they know well than by strangers and acquaintances, but these findings are based on retrospective accounts of hurtful events. This study examined the moderating effect of familiarity on hurt feelings among people who have recently become acquainted. Participants were led to experience either a relatively low or high degree of familiarity with a confederate. Afterwards, the confederate chose to listen either primarily to them or another participant as they talked about themselves. Results showed that participants were significantly more hurt when they were ignored by a confederate who barely knew them than by a confederate who was more familiar with them. Effects of being ignored showed a similar pattern on a measure of state self-esteem.
Adsorption Kinetics for Urban Rainfall-Runoff Metals by Composite Oxide-Coated Polymeric Media

A manganese oxide-coated polymeric media (MOPM) utilized in sorptive filtration systems as a rainfall-runoff or snowmelt unit operation and process media was characterized using scanning electronic microscopy and adsorption kinetics were studied using a flow-through batch reactor. Results indicated the MOPM adsorption kinetics can be described as a fast adsorption reaction occurring within 30 min followed by a slower reaction that continued from 5 to 15 h, as a function of initial pH and sorbent dosages. A potential driving kinetic model was developed based on an elementary second-order rate law. Modeled results were compared to experimental data using this model and a series of comparative kinetic models. Manganese oxide surface morphology and the ability of a parabolic diffusion model to predict the adsorption kinetics of MOPM suggest diffusion-controlled adsorption for divalent heavy metals on MOPM. Based on a goodness of fit test, the potential driving model best represented the experimental data. Using the potential driving model, it was found that rate constants increased with increasing solution pH, but were independent of sorbent dosages. Results indicated that metal ions with the highest adsorption affinity had the highest rate constants. Observed porosity, the excellent fit of the potential driving model, and breaks in Elovich model plots all suggest a complex adsorption mechanism. Results suggest MOPM can be an effective media for rainfall-runoff and snowmelt metal adsorption.
Use of medroxyprogesterone acetate in the treatment of Müllerian adenosarcoma: a case report.

Abstract Background. Mullerianadenosarcoma is a rare pelvic malignancy that most commonly arises from the endometrium. These tumors are relatively insensitive to chemotherapy and radiation and are primarily treated by surgical resection. We report a case of mullerian adenosarcoma arising outside of the uterus from a background of endometriosis treated with a combination of surgical resection and medroxyprogesterone acetate. Case. A 43-year-old woman with a history of endometriosis was diagnosed with advanced extrauterine mullerian adenosarcoma. After suboptimal tumor dubulking surgery she was treated with medroxyprogesterone acetate. Ten months postoperatively she remains without evidence of disease. Conclusion. Medroxyprogesterone acetate may be a useful drug in the treatment of advanced mullerian adenosarcoma.
Aging per se is an independent risk factor for cholesterol gallstone formation in gallstone susceptible mice.

Cholesterol gallstones occur rarely in childhood and adolescence and increase linearly with age in both genders. To explore whether aging per se increases cholesterol saturation of bile and gallstone prevalence, and to investigate age-related changes in hepatic and biliary lipid metabolism, we studied gallstone-susceptible C57L mice and resistant AKR mice of both genders fed 8 weeks with a lithogenic diet containing 1% cholesterol, 0.5% cholic acid, and 15% butter fat starting at (young adu33369) 8, (older adult) 36, and (aged) 50-weeks-of-age. After the 8-week feeding, gallstone prevalence, gallbladder size, biliary lipid secretion rate, and HMG-CoA reductase activity were significantly greater but cholesterol 7α-hydroxylase activity was lower in C57L mice of both genders compared with AKR mice. Increasing age augmented biliary secretion and intestinal absorption of cholesterol, reduced hepatic synthesis and biliary secretion of bile salts, and decreased gallbladder contractility, all of which increased susceptibility to cholesterol cholelithiasis in C57L mice. We conclude that aging per se is an independent risk factor for cholesterol gallstone formation. Because aging increases significantly biliary cholesterol hypersecretion and gallstone prevalence in C57L mice carrying Lith genes, it is highly like that Longevity (aging) genes can enhance lithogenesis of Lith (gallstone) genes.
Classifying neural networks

Certain aspects of the classification of discrete synchronous neural networks are examined. Neural networks with different weights and thresholds may give rise to the same dynamics digraphs. These networks are said to be isomorphic. Testing the isomorphism of dynamics digraphs results in two different classes of digraphs: labeled or unlabeled. The corresponding decision problems are called strong-isomorphism testing (SIT) and weak-isomorphism testing (WIT). Several results which show that the nature of these problems is in contrast with that of the graph-isomorphism problem are proven. For instance, SIT is coNP-complete, and WIT is NP-hard (even for symmetric networks) despite several structural restrictions of the digraphs under consideration. The reductions also show that predecessor counting is Hash P-complete. >
Applications of "planar-chiral" heterocycles in asymmetric catalysis

Planar-chiral derivatives of pyridine function as efficient catalysts for processes such as the kinetic resolution of primary amines and the desymmetrization/ring-opening of meso epoxides. Planar-chiral pyrrolyl and phospholyl derivatives serve as effective chiral lig- ands for a range of metal-catalyzed reactions, including the copper-catalyzed ring-expansion of oxetanes and the rhodium-catalyzed isomerization of allylic alcohols.
Secure messaging and diabetes management: experiences and perspectives of patient portal users

Background Patient portal use has been associated with favorable outcomes, but we know less about how patients use and benefit from specific patient portal features. Objective Using mixed-methods, we explored how adults with type 2 diabetes (T2DM) use and benefit from secure messaging (SM) within a patient portal. Methods Adults with T2DM who had used a patient portal participated in a focus group and completed a survey (n=39) or completed a survey only (n=15). We performed thematic analysis of focus group transcripts to identify the benefits of and barriers to using SM within a portal. We also examined the association between use of various patient portal features and patients' glycemic control. Results Participants were on average 57.1 years old; 65% were female; 76% were Caucasian/White, and 20% were African American/Black. Self-reported benefits of SM within a portal included enhanced patient satisfaction, enhanced efficiency and quality of face-to-face visits, and access to clinical care outside traditional face-to-face visits . Self-reported barriers to using SM within a portal included preconceived beliefs or rules about SM and prior negative experiences with SM. Participants' assumptions about providers' opinions about SM and providers' instructions about SM also influenced use. Greater self-reported use of SM to manage a medical appointment was significantly associated with patients' glycemic control (ρ=−0.29, p=0.04). Conclusion SM within a portal may facilitate access to care, enhance the quality of office visits, and be associated with patient satisfaction and clinical outcomes for patients with diabetes, but provider communication about SM is essential.
Social, Personality, and Gender Differences in At-Risk and Not-At-Risk Sixth-Grade Students:

Research has been presented that identifies in-school factors associated with at-risk adolescent students, but less attention has been given to the social-psychological perceptions that these students hold about themselves and their school experiences. Knowledge of these social-psychological perceptions can be used for designing at-risk prevention and intervention programs. This study examined differences between 219 at-risk sixth-grade students and 218 students who were not defined as at risk on four social-psychological domains: attitudes toward school, self-concept, locus of control, and parent-child relations. The results showed that at-risk students had significantly less positive attitudes toward their school experience, lower self-concepts, more external control orientations, and viewed their parents as less demanding and more casual in their expectations. Female at-risk students tended to have more positive attitudes toward school and viewed their mothers as more loving than did male at-risk stude...
Biquad Gm-C structures which use double-output transconductors

Two Gm-C biquad structures are derived. They use only two grounded capacitors and three transconductors, two of which have double-outputs. The realization of the double-output transconductors is discussed. It is shown that only two additional transistors are needed to convert a single-output transconductor to a double-output one suitable for implementation of the proposed structures. HSPICE simulations and experimental results of a 5-th order inverse Gaussian filter using the proposed biquad structures are given.
The Political Lessons of Depression-Era Banking Reform *

Ironically, the primary motivations for the main bank regulatory reforms in the 1930s (Regulation Q, the separation of investment banking from commercial banking, and the creation of federal deposit insurance) were to preserve and enhance two of the most disastrous policies that contributed to the severity and depth of the Great Depression – unit banking and the real bills doctrine. Other regulatory changes, affecting the allocation of power between the Fed and the Treasury, were intended to reduce the independence of the Fed, while giving the opposite impression. The ill-conceived banking legislation of the 1930s took very little time to pass, but a great deal of time to disappear. The overarching lesson is that the aftermath of crises are moments of high risk in public policy. The Great Depression provoked banking reform legislation that was quick, comprehensive, and unusually responsive to popular opinion. Each of these three aspects increases the risk that regulation will have adverse consequences.
A clinician's approach to acute low back pain

Two important goals in treating acute low back pain are to return the patient to regular activity as quickly as possible and to do so in a manner that is cost-effective. By following a logical treatment protocol, the clinician is often able to provide the treatment necessary to provide the patient with relief. Referral to an orthopedist or neurosurgeon may be appropriate in only a minority of cases. Thus, after the initial history and physical examination, ruling out (or in) conditions that require urgent or emergent care is essential. These conditions include cauda equina syndrome, circulatory collapse due to expanding abdominal aortic aneurysm, and tumor, infection, and other underlying disorders as a cause of low back pain. Patients without these conditions can be started on conservative therapy—without radiographic or laboratory tests—regardless of the specific diagnosis. Conservative therapy consists of passage of time, controlled physical activity, physical modalities (e.g., cryotherapy or thermotherapy), local injections, nonsteroidal anti-inflammatory drugs, and muscle relaxants. Because low back pain is so common, even the small proportion of patients who do not improve after 6 weeks of conservative therapy represents a sizable number. The location and radiation of pain are used as initial guides to classifying these patients into four groups: those with localized pain, sciatica, anterior thigh pain, or posterior thigh pain. Each follows a different diagnostic path, which will be described herein.
Audit committee characteristics and investment in internal auditing

Regulators and others recently highlighted the increasingly important role of internal auditing in supporting and interacting with the audit committee to ensure the integrity and quality of financial reporting. Likewise, one of the roles of the audit committee is to oversee the quality of monitoring mechanisms implemented by the firm, which includes the internal audit function. However, our understanding of the relationship between the audit committee and internal auditing is limited. We fill this void by providing the first empirical evidence of the association between audit committee characteristics and the investment in internal auditing. Our analyses, from a sample of 181 SEC registrants, suggest that the investment in internal auditing (internal audit budget) is negatively related to the presence of auditing experts on the committee and the average tenure of audit committee members, but positively related to the number of audit committee meetings (a proxy for audit committee diligence). These observations suggest potential complementary and substitution effects between the audit committee and internal auditing, and thus raise important implications for future research.
A Method for Realizing the Negative-Impedance Inverter

A negative-impedance inverter (NIV) can be used to realize the negative dual of any driving-point function. This paper describes a scheme by which two controlled sources are connected in series to realize the NIV, and the basic principle involved is de-lineated. The feasibility of such a scheme is demonstrated by using, in place of each controlled source, a transistor amplifier that uses a common-base stage and a common-collector stage in cascade. The transistor amplifier requires only one power supply and is readily adaptable for integrated-circuit applications. Experimental results showing the realizability of the negative resistance, the negative capacitance, and the negative inductance by this NIV circuit are presented.
Modeling the influence of action on spatial attention in visual interactive environments

A large number of studies have been reported on top-down influences of visual attention. However, less progress have been made in understanding and modeling its mechanisms in real-world tasks. In this paper, we propose an approach for learning spatial attention taking into account influences of physical actions on top-down attention. For this purpose, we focus on interactive visual environments (video games) which are modest real-world simulations, where a player has to attend to certain aspects of visual stimuli and perform actions to achieve a goal. The basic idea is to learn a mapping from current mental state of the game player, represented by past actions and observations, to its gaze fixation. A data-driven approach is followed where we train a model from the data of some players and test it over a new subject. In particular, two contributions this paper makes are: 1) employing multi-modal information including mean eye position, gist of a scene, physical actions, bottom-up saliency, and tagged events for state representation and 2) analysis of different methods of combining bottom-up and top-down influences. Comparing with other top-down task-driven and bottom-up spatio-temporal models, our approach shows higher NSS scores in predicting eye positions.
Pairing of the nucleotide binding domains of the transporter associated with antigen processing.

Abstract The transporter associated with antigen processing (TAP) comprises two structurally related subunits, TAP1 and TAP2, that form stable complexes in endoplasmic reticulum (ER) membranes. TAP complexes function in the translocation of peptides from the cytosol into the ER lumen for presentation by major histocompatibility complex class I molecules. Each TAP subunit contains an N-terminal membrane-spanning region with multiple membrane-spanning segments, and a C-terminal, cytosolic nucleotide binding region. To study the nature of the interactions occurring on the cytosolic face of TAP1/TAP2 complexes, we investigated quaternary associations mediated by two C-terminal fragments of human TAP1 (T1c, residues 452–748 and T1ctr, residues 472–748) and two C-terminal fragments of human TAP2 (T2c, residues 399–686 and T2ctr, residues 433–686). Each of these constructs contains the core nucleotide binding region as well as a long or short N-terminal extension. We show stable complex formation between T1c and T2c but not between T1ctr and T2ctr. The mechanistic implications of these results are discussed. We also show that each of the constructs except T1ctr interacts with wild type TAP1 and TAP2, indicating possibilities for homodimerization of TAP1 and TAP2, or of oligomerization of TAP1/TAP2 heterodimers on membranes.
Coexisting psychogenic and neurogenic dysphonia: A source of diagnostic confusion

Four patients are described who had neurologic disease and accompanying dysphonia that proved to he partially or entirely psychogenic. The findings suggest that the association of a speech disorder with organic disease does not necessarily imply a causal relationship, even when the speech signs seem to arise from the site or organ system affected by disease. The potential for psychogenic factors to confuse the differential neurologic diagnosis of speech disorders is emphasised.
METALLURGY, MAYAPAN, AND THE POSTCLASSIC MESOAMERICAN WORLD SYSTEM

Residents of Mayapan produced and consumed metal artifacts through long-distance commercial exchange networks in the Postclassic Mesoamerican world system. In this paper, I perform a stylistic and typological analysis of metal artifacts and debris from lost-wax casting from recent excavations at Mayapan, with reference to previously excavated collections by the Carnegie Institution of Washington, DC. The distribution of metal artifacts suggests that metal objects were not sumptuary goods restricted to elites, but luxury goods availble to those who could afford them. I then compare Mayapan with other sites in the Postclassic Mesoamerican world system that were involved in the interregional distribution of metal artifacts. Although Mayapan did not have local sources of native metal or a longstanding traditions of metalworking, it was able to use its economic influence in the world system to obtain and create metal objects specific to its needs.
Sleep-associated breathing disorders in morbidly obese children and adolescents

Forty-one children and adolescents with a history of breathing difficulty during sleep and morbid obesity, defined as greater than 150% ideal body weight, underwent polysomnography to determine the incidence of sleep-associated breathing disorders. Seventeen patients also performed pulmonary function testing. The mean patient age was 10.3±4.4 (SD) years, and mean percent of ideal body weight was 208±42.2. A sleep history questionnaire showed that all patients snored, but frank apnea was reported in only 32%. The pulmonary fuction tests showed 18% (3/17) with a restrictive defect and 47% (8/17) with obstructive changes. The polysomnograms in 37% (15/41) of the patients were abnormal because of apnea, hypopnea, excessive arousals, or abnormalities in gas exchange. Multiple regression analysis demonstrated no significant association between weight, age, or gender and any physiologic measure on the polysomnogram. Most of the abnormal polysomnograms (13/15) were mildly abnormal, but two showed sufficiently severe abnormalities to require clinical intervention. We conclude that children and adolescents with morbid obesity are at risk for sleep-associated breathing disorders; their polysomnographic abnormalities are usually mild but rarely may be severe enough to require clinical intervention.
Malignant perivascular epithelioid cell tumor (PEComa) of the uterus with late renal and pulmonary metastases: a case report with review of the literature

Background Perivascular epithelioid cell tumor (PEComa), other than angiomyolipoma (AML), clear cell sugar tumor (CCST), and lymphangioleiomyomatosis (LAM), is a very rare mesenchymal tumor with an unpredictable natural history. The uterus is the most prevalent reported site of involvement of PEComa-not otherwise specified (PEComa-NOS). To the best of our knowledge, about 100 PEComa-NOS have been reported in the English Language medical literature, of which 38 were uterine PEComa-NOS. These reported cases of uterine PEComa-NOS have usually shown clinically benign behavior, but 13 tumors, three of them associated with tuberous sclerosis complex (TSC), exhibited local aggressive behavior and four of them showed distant metastases.
Structure-property relationships in acrylate/epoxy interpenetrating polymer networks : Effects of the reaction sequence and composition

Interpenetrating polymer networks (IPNs) of poly(ethylene glycol) 200 diacrylate and diglycidyl ether of bisphenol A were formed over a range of compositions and with different reaction sequences. We controlled the reaction sequence by thermally initiating the cationic epoxy polymerization, photoinitiating the free-radical acrylate polymerization, and changing the processing order. The reaction was monitored by attenuated total reflectance Fourier transform infrared spectroscopy, photo differential scanning calorimetry. and modulated differential scanning calorimetry (mDSC). The glass-transition temperature was estimated from mDSC. Mechanical and rheological tests provided the strength and hardness of the materials. Morphology and phase separation were explored with optical and scanning electron microscopy. All of the physical properties were dependent on IPN composition. Some properties and the morphology were dependent on the reaction sequence. Significant differences in glass-transition temperature were observed at the same composition but with different reaction sequences. Even with minimal structure, correlations existed between the morphology and material properties with partially phase-separated samples exhibiting maximum damping. The rapid reaction allowed minimal phase separation, yet different reaction sequences resulted in significantly different properties. This systematic study indicated that the relationships between phase morphology, processing, and the physical properties of IPNs are complex and not predictable a priori. © 2007 Wiley Periodicals, Inc.

Transfer of development rights in theory and practice: The restructuring of TDR to incentivize development

In the 2000s, Florida local governments began using transfer of development rights (TDR) to enable a mix of conservation and development rights on large landholdings in rural areas. While the theoretical function of TDR is to facilitate a market for development rights exchanges, these programs envision little or no exchange of development rights, and instead use TDR as part of effectuating new development conditions. Previous research on TDR focuses on program performance, and provides little insight into why TDR programs might differ in theory and practice. In this research, I explore the design and orientation of Florida’s emergent rural TDR programs. I argue that these programs restructure TDR primarily as an incentive rather than its theoretical function of enabling a market in support of managed growth. As a result, these programs are biased toward development over conservation. The programs also present an ambiguous treatment of property and development rights. The research raises questions about how well market-based land use strategies deliver “win–win” outcomes that balance economic growth and environmental protection.
Education and the Prevention of Alcoholism

Prevention and control of alcohol problems have received increasing attention from the scientific and professional communities in recent years, especially in the United States. Beginning with the initial report of the Cooperative Commission on the Study of Alcoholism (Plaut, 1967), and followed by the Commission’s report on prevention (Wilkinson, 1970), this trend has continued and accelerated since the establishment of the National Institute on Alcohol Abuse and Alcoholism (NIAAA) in 1971. Education has been advanced as a major tool of prevention in the United States, although in other countries education may assume a less prominent role. In this chapter, attention is directed to (1) a description and discussion of major models of prevention; (2) an account of the principal techniques of prevention; (3) detailed discussion of alcohol education as a critical technique of prevention; and (4) an analysis of some key issues in preventive and educational action.
Microwave spectrum and gas phase structure of maleimide

Abstract The rotational spectrum of maleimide was measured in the 5–12 GHz range using a Flygare–Balle type, pulsed-beam Fourier transform microwave spectrometer. Rotational transitions were measured for the parent, all unique singly substituted 13 C isotopologues, and an ND, deuterium substituted isotopologue. The parent (or normal isotopologue) rotational constants, centrifugal distortion constants, and quadrupole coupling constants are A = 6815.3251(12) MHz, B = 2361.85011(64) MHz, C = 1754.32750(64) MHz, D J = 0.232(24) kHz, D JK = 0.546(54) kHz, 1.5 χ aa = 2.4227(53) MHz, and 0.25( χ bb – χ cc ) = 1.3679(15) MHz. A best fit gas phase structure was determined using the experimental rotational constants of the isotopologues and some parameters from calculations. The inertial defect is Δ = −0.054 amu A 2 , indicating a planar structure for maleimide, with no large amplitude motions observed on the NH hydrogen atom. Calculations using B3LYP/aug-cc-pVTZ provided rotational constants which are much closer (within 1–2%) to the experimental values compared to the MP2/aug-cc-pVTZ calculated values.

Fine Structure of Na 4 d D 2 Using High-Resolution Two-Photon Spectroscopy

We have measured the fine-structure splitting of the $4d^{2}D$ state of neutral sodium using high-resolution, cw, simultaneous two-photon excitation from the $3s^{2}S$ ground state. Sodium atoms in an atomic beam were excited by a single-mode, cw, tunable dye laser, and the resonance was detected by monitoring the decay fluorescence from the excited state. The fine structure of the $4d^{2}D$ state was well resolved and measured to be ${\ensuremath{\Delta}}_{\mathrm{fs}}=1025\ifmmode\pm\else\textpm\fi{}6$ MHz.
Interfacial Structure of Room-Temperature Ionic Liquids at the Solid-Liquid Interface as Probed by Sum Frequency Generation Spectroscopy.

Fundamental and basic information about molecules at the solid–liquid interface is limited primarily because most spectroscopic methods are not able to specifically detect the surface buried between two condensed phases. The second-order nonlinear techniques sum frequency generation (SFG) is able to probe the noncentrosymmetric environment between two bulk phases and has been used in many surface studies. In this Perspective, the use of SFG in studies of ionic liquids at the solid–liquid interface will be discussed. Several interfaces are discussed including dielectrics, semiconductors, and metal. SFG results suggest a specific surface model that the ionic liquid structure persists approximately one layer into the bulk liquid and that this is mostly due to the charge neutralization at the surface.
Interfacial Fracture Toughness of a Plasma Sprayed Hydroxyapatite Coating Used for Orthopedic Implants

This study introduces a new method for evaluating the adhesion strength of a coating on a substrate. The interfacial fracture toughness, Γ i is used to assess the work per unit area required to separate an interface. Γ i is measured for the as-received specimens of hydroxyapatite plasma sprayed on Ti-6A1-4V substrate. Calculation of the interfacial fracture toughness requires that the elastic modulus of the coating to be known. The Young's modulus of the plasma sprayed hydroxyapatite is assessed using a bend test. The effect of aqueous environment on the interfacial fracture toughness is also investigated.
The Mating Behavior of the Western Corn Rootworm Diabrotica virgifera (Coleoptera: Chrysomelidae)

The sequence of mating behavior for virgin western corn rootworms, Diabrotica virgifera LeConte, included the following behavioral categories: preliminary courtship and mounting; physical stimulation of the female by the male; and copulation. Various tactile stimuli, including antennal palpitation and stroking activities involving the mesothoracic legs, were performed by the male during the mating process.
Absolute Intensities of Radiative Deexcitation of 46Sc

The absolute radiative widths for E-1 and M-1 transitions in 46Sc have been determined by neutron time-of-flight spectrometry. The level structure of 46Sc to 3 MeV has been studied by combining (n,γ) data with previous charged particle data. As in 36Cl scandium shows enhanced M-1’s.
Deterministic Equilibrium Selection Under Payoff-Perturbed Dynamics

This paper studies models of population game dynamics where players make stochastic choices because of payoff perturbations. The goal is to obtain deterministic equilibrium selection, where the action distribution in the population globally converges to Nash equilibria with probability 1 in a finite time, under a moderate level of payoff perturbations. Exploiting the tractable nature of bounded perturbations, we characterize almost-sure global stability in a finite population setting by generalizing risk-dominance in many action games. We also characterize conditions for (approximate) global asymptotic stability under a continuum population setting allowing unbounded perturbations; this leads to a stronger conclusion that waiting times are uniformly bounded in the population size.
Evaluation of the dizzy patient.

This discussion has focused primarily on the history and physical examination of the patient with dizziness which, in fact, are the two most important elements in the evaluation process. To perform the examination expeditiously and completely, a broad differential diagnosis of dizziness must be kept in mind. The clinician should also keep in mind two basic objectives: first, to identify serious pathology (e.g., central nervous system lesion, brainstem ischemia, cardiac arrhythmia); and second, to recognize diseases that can be specifically treated, such as an endocrine abnormality, middle ear infection, Meniere's disease, or a drug reaction. Reassurance and/or vestibular rehabilitation are the mainstays of therapy for the patients not falling into the above two categories.
Immune cytolysis of human renal carcinoma mediated by xenogeneic immune ribonucleic acid.

AbstractWith a microcytotoxicity assay It was shown that normal, non-Immune human lymphocytes were converted to effector cells specifically cytotoxic to human renal carcinoma cells after incubation with xenogeneic immune ribonucleic acid The ribonucleic acid was extracted from the lymphoid tissues of sheep that had been immunized with human renal carcinoma tissue. Lymphocytes incubated without ribonucleic acid or with ribonucleic acid from sheep Immunized with Freund’s adjuvant alone did not increase cytotoxicity.Immunotherapy with immune ribonucleic acid increased cytotoxic activity of lymphocytes from a patient with metastatic renal carcinoma. The microcytotoxicity assay may be a useful method to assessing the cellular immune response in patients receiving immunotherapy and seems to correlate with their clinical course.
Monitoring renal function.

Acute renal failure is a common cause of morbidity and mortality in critically ill patients. The prompt, effective management of acute oliguria, frequently the presenting sign of renal deterioration, remains difficult because of the Iack of suitable monitors. No monitor presently in common use is sufficiently specific, sensitive, or rapidly available to satisfy clinical needs.
Remarks on a “Framework for Social and Ethical Issues” Report

This paper brings a contribution to the clarification of a conceptual framework and rationale presented for defining and integrating ethical and social issues into computer science curriculum. It tries to take into account the reflection on the subject for the last 25 years and suggests a new framework which simplifies the proposal, but keeps its main features.
Smart Cement Piezoresistivity Characterization with Sodium Metasilicate under Temperature and Curing Environments for Oil Well–Cementing

AbstractThe smart cement behavior with 0.3% sodium metasilicate (SMS) at 80°C (176°F) under two different environments was investigated in this study. The smart cement was made using the class H oil well cement and 0.1% conductive filler to make it a bulk chemo-piezoresistive material with highly sensing property. The smart cement was cured in air and also submerged in water-saturated sand at 80°C up to 28 days. The smart cement initial resistivity (ρo) decreased from 0.97 to 0.87 Ω·m with 0.3% SMS, a 10% decrease. Similarly the minimum resistivity (ρmin) decreased from 0.81 to 0.72 Ω·m with 0.3% SMS, an 11% decrease, which is an indication of the chemo-resistivity of the smart cement. The resistivity changes were higher than the unit weight changes in the smart material. The resistivity of the smart material oven cured in saturated sand at 80°C was 55 to 75% less than the resistivity of the material cured at 80°C after curing for one, seven, and 28 days. The material resistivity with 0.3% SMS cured in ...
Die Innervation der Bauchspeicheldrüse

Das Pankreas ist recht reichhaltig mit Nerven ausgestattet. Vom Plexus hepaticus, lienalis und mesentericus inferior ziehen Nerven zur Druse und halten sich, wie bei allen drusigen Organen, zunachst an den Verlauf der Blutgefase. Sie scheinen alle aus dem sympathischen Nervensystem zu stammen, doch sprechen, wie wir spater sehen werden, physiologische Erfahrungen dafur, das auch der Vagus an der Nervenversorgung des Pankreas beteiligt ist. Wir mussen somit annehmen, das den zur Druse ziehenden Nerven schon vorher Vagusfasern beigemischt wurden, munden doch solche immer in den Plexus solaris ein.
Measuring Concurrency Attitudes: Development and Validation of a Vignette-Based Scale.

BACKGROUND Concurrent sexual partnerships (partnerships that overlap in time) may contribute to higher rates of HIV transmission in African Americans. Attitudes toward a behavior constitute an important component of most models of health-related behavior and behavioral change. We have developed a scale, employing realistic vignettes that appear to reliably measure attitudes about concurrency in young African American adults. METHODS Vignette-based items to assess attitudes about concurrency were developed following focus groups and cognitive testing of items adapted from existing scales assessing psychosocial constructs surrounding related sexual behaviors. The new items were included in a telephone survey of African American adults (18-34 years old) in Eastern North Carolina immediately before and after a radio campaign designed to discourage concurrency. We performed an exploratory factor analysis on each sample (pre- and post-campaign) to cross-validate results. We retained factors with a primary loading of ≥0.50 and no secondary loading >0.30. Cronbach's coefficient alpha was used to evaluate internal reliability. Associations in the predicted direction between the mean responses to items on the final factor and known correlates of concurrency validated the scale. RESULTS Factor analysis in a random pre-campaign subsample yielded a one-factor 6-item scale with acceptable internal consistency (Cronbach's α = 0.79). As expected, the attitude factor was positively associated with participation in concurrent partnerships, whether assessed by self-report (r = 0.298, p<0.0001) or deduced from dates of recent sexual partnerships (r = 0.298, p<0.0001). The factor was also positively associated with alcohol (r = 0.216, p<0.0001) and drug use (r = 0.225, p<0.0001) and negatively associated with increasing age (r = -0.088, p- = 0.02) and female gender (r = -0.232, p<0.0001). Factor analyses repeated in the second random pre-campaign subsample and post-campaign sample confirmed these results. CONCLUSION A vignette-based scale may be an effective measure of key attitudes related to concurrency and potentially a useful tool to evaluate interventions addressing this network pattern.

Evolocumab is generally safe and effective at lowering serum LDL cholesterol levels for select patients who need marked cholesterol reduction and can tolerate injections. However, it remains unknown whether evolocumab prevents premature death from cardiovascular events.
Introduction: Subjects of Militarization

The introduction argues that militarization has been a defining feature of modernity in the Greater Caribbean. It frames the case-studies presented in the volume by placing them in relation to a wider and longer history of Caribbean military encounters that includes but is not confined to US interventions, revealing commonalities in Caribbean experiences of militarization that are obscured by studies that focus on only one language area of the Caribbean. The introduction lays out the volume’s humanities-driven emphasis on everyday life, subjectivity, and culture as they interact with systemic forces. It recognizes the massive imposition of power through violence and extremes of inequality, and massive resistance to it, while also noting how ordinary people from positions of subordination negotiated, appropriated, and strategically manipulated whatever limited opportunities relationships with militaries afforded.
Deictics and the construction of mathematics and science knowledge in the secondary school classroom

AbstractTaking a Teacher Language Awareness (TLA) perspective, this paper examines how the concept of deixis is employed in oral discourse in two secondary science and mathematics classes in the southwestern part of the US. Drawing on audio and videotaped data from two classrooms, we examine how verbal deixis, or words and phrases that cannot be fully understood without additional context, serves as a potential resource for the organisation of learning processes. We further consider how deixis may act as an impediment to the organisation of learning processes. We outline implications for preparation of teachers of English Language Learners in Science, Technology, Engineering and Mathematics areas, with a specific focus on middle and high school science and mathematics.
Complex permittivity characterization based on the matrix-pencil method for objects on the human body

In this contribution we deal with the problem of accurately identifying complex permittivities of dielectric objects placed on a conducting surface. Solutions to this problem are becoming increasingly crucial in sensing security scenarios in order to detect forbidden materials concealed on the human body. The proposed approach uses the matrix pencil method (MPM) as an efficient post-processing tool for spectral analysis of multiple frequencies at the millimeter-wave range. Unlike previously reported methods for permittivity discrimination based on multiple-frequency mm-wave SAR (synthetic aperture radar), our approach does not require multiple receivers. Moreover, those previous SAR-based techniques can only be applied to ideally lossless dielectric objects. Additionally, contrasting with previous methods based on the MPM, the work herein presented requires neither bulky transmission lines nor difficult time measurements on pulse delays. Representative examples based on full wave simulations are provided to show good accuracy for complex permittivity estimation.
The Management of Vascular Malformations of the Airway: Natural History, Investigations, Medical, Surgical and Radiological Management

Vascular malformations may affect nearly all aspects of the upper airway. Each type of malformation has a characteristic pattern of disease. These lesions may be focal or diffuse, and require directed management strategies. Physicians treating these entities should have a high level of suspicion to consider airway evaluation even in the absence of overt symptoms. However, cutaneous head and neck venous malformations or other lesions affecting the lips, oral cavity, or tongue can herald the presence of coexisting airway lesions. A multidisciplinary approach is critical in achieving comprehensive treatment.
A Multi-season Investigation of Microbial Extracellular Enzyme Activities in Two Temperate Coastal North Carolina Rivers: Evidence of Spatial but Not Seasonal Patterns.

Riverine systems are important sites for the production, transport, and transformation of organic matter. Much of the organic matter processing is carried out by heterotrophic microbial communities, whose activities may be spatially and temporally variable. In an effort to capture and evaluate some of this variability, we sampled four sites – two upstream and two downstream – at each of two North Carolina rivers (the Neuse River and the Tar-Pamlico River) ca. twelve times over a time period of 20 months from 2010 to 2012. At all of the sites and dates, we measured the activities of extracellular enzymes used to hydrolyze polysaccharides and peptides, and thus to initiate heterotrophic carbon processing. We additionally measured bacterial abundance, bacterial production, phosphatase activities, and dissolved organic carbon (DOC) concentrations. Concurrent collection of physical data (stream flow, temperature, salinity, dissolved oxygen) enabled us to explore possible connections between physiochemical parameters and microbial activities throughout this time period. The two rivers, both of which drain into Pamlico Sound, differed somewhat in microbial activities and characteristics: the Tar-Pamlico River showed higher -glucosidase and phosphatase activities, and frequently had higher peptidase activities at the lower reaches, than the Neuse River. The lower reaches of the Neuse River, however, had much higher DOC concentrations than any site in the Tar River. Both rivers showed activities of a broad range of polysaccharide hydrolases through all stations and seasons, suggesting that the microbial communities are well-equipped to access enzymatically a broad range of substrates. Considerable temporal and spatial variability in microbial activities was evident, variability that was not closely related to factors such as temperature and season. However, Hurricane Irene’s passage through North Carolina coincided with higher concentrations of DOC at the downstream sampling sites of both rivers. This DOC maximum persisted into the month following the hurricane, when it continued to stimulate bacterial protein production and phosphatase activity in the Neuse River, but not in the Tar-Pamlico River. Microbial community activities are related to a complex array of factors, whose interactions vary considerably with time and space.

Urine Volume and Nitrogen Excretion are Altered by Feeding Birdsfoot Trefoil Compared with Alfalfa in Lactating Dairy Cows

Legumes that contain condensed tannins may have lower ruminal protein degradation than alfalfa. The present study investigated the effects of feeding birdsfoot trefoil (Lotus corniculatus L.) hay on lactational performance and N utilization and excretion. Eight multiparous Holstein cows in midlactation (150 ± 22.3 d-in-milk) were randomly assigned to 2 treatments [alfalfa hay-based total mixed ration (AHT) or birdsfoot trefoil hay-based total mixed ration (BHT)] in a crossover design with 2 experimental periods. Each experimental period lasted 17 d (14 d of adaptation and 3 d of sampling and total collection). Hays comprised approximately 50% of DM in experimental diets. There were no treatment effects on dry matter intake (DMI; 21.4 vs. 20.7 kg/d), milk yield (29.4 vs. 28.1 kg/d), milk fat concentration (3.20% vs. 3.21%), and milk protein concentration (3.20% vs. 3.16%) for AHT and BHT, respectively. In addition, dietary treatments did not affect milk yield/DMI or energy-corrected milk yield/DMI. In contrast, apparent crude protein digestion decreased in cows fed BHT compared with those fed AHT (60.7% vs. 69.1%). Concentration of milk urea-N decreased by feeding BHT compared with AHT (11.9 vs. 13.3 mg/100 mL), whereas total N excretion did not differ between AHT and BHT diets. However, cows fed BHT excreted more N in feces (194 vs. 168 g/d), whereas urinary N excretion was lower compared with cows fed AHT. The shift of N to feces resulted in a decrease in urinary N:fecal N ratio in cows fed BHT relative to those fed AHT. Overall results in the current study suggest that feeding birdsfoot trefoil in dairy diets shifts routes of N from urine to feces compared with feeding alfalfa hay, with little effect on lactational performance. Reduction in urinary N and any impact on environment may be attributed to functional effect of condensed tannins in birdsfoot trefoil hay.
