Self-esteem, need for approval, and reactions to personal evaluations

Abstract In accordance with theoretical predictions concerning the reactions of high and low self-esteem individuals, S s with low self-esteem scores showed an increase in liking for a positive evaluator of self and a decrease in liking for a negative evaluator of self. S s with high self-esteem scores and low Marlowe-Crowne scores did not show a significant change in liking for either a positive or negative evaluator of self. S s with high self-esteem scores and high Marlowe-Crowne scores showed a pattern of reaction similar to that of low self-esteem S s. It was suggested that a sizable percentage of high self-esteem scorers should be reclassified as low self-esteem. This subgroup seems to obtain high scores on a self-esteem inventory by presenting themselves in an overly favorable as opposed to honest manner (the defining characteristic of a high Marlowe-Crowne scorer) but shows behavior patterns similar to low self-esteem individuals.
Digital characteristics of a CMOS ternary inverter at the liquid nitrogen temperature

Abstract Static and dynamic performance of a CMOS ternary inverter has been studied in the MOSFET's threshold voltage region at the liquid nitrogen temperature (77K), and compared with the corresponding room temperature (296K) operation. It is observed that the positive ternary inverter (PTI), simple ternary inverter (STI) and negative ternary inverter (NTI) exhibit sharper voltage transfer characteristics and improved transient response at the liquid nitrogen temperature.
Is rat skeletal muscle hexokinase an allosteric enzyme

A recent report by M. Gregoriou, I. P. Trayer, and A. Cornish-Bowden (1986, Eur. J. Biochem.161, 171–176) showed that the mechanism for rat skeletal muscle hexokinase contains two allosteric sites: one for ATP and one for glucose 6-phosphate. In this report, we show that the allosteric mechanism is at variance with a large amount of kinetic data for the skeletal muscle hexokinase reaction in the literature. In addition, the allosteric mechanism conflicts with isotope exchange at chemical equilibrium data reported by M. Gregoriou, I. P. Trayer, and A. Cornish-Bowden (1983, Eur. J. Biochem. 134, 283–288).
Low-temperature specific heat of Ti-Hf alloys

The effect of alloying on the specific heat of Ti-Hf alloys has been investigated in the temperature range 1.2–4.5 K. A maximum is observed in the electronic specific heat coefficient γ around 35 at % Ti and the Debye temperature θ D decreases from titanium to hafnium. No superconductivity is found down to the lowest temperature studied.
Vibrational frequencies and structural determinations of tetraethynylsilane

Abstract The normal mode frequencies and corresponding vibrational assignments of Si(CCH) 4 are examined theoretically using the gaussian 98 set of quantum chemistry codes. Each of the vibrational modes was assigned to one of six types of motion predicted by a group theoretical analysis (Si–C stretch, CC stretch, C–H stretch, CC–H bend, Si–CC bend, and C–Si–C bend) utilizing the T d symmetry of the molecule. A set of uniform scaling factors was derived for each type of motion. Predicted infrared and Raman intensities are reported.
Writing the Victorian City: discourses of risk, connection, and inevitability.

A n essayist writing in the 1860 All the Year Round reflected that "it concerns a man more to know his risks of the fifty illnesses that may throw him on his back, than the possible date of the one death that must come" ("Registration of Sickness" 228). This seemingly unimpressive statement about the value of statistics is remarkable for a number of reasons. The editor, Charles Dickens, had himself famously caricatured and critiqued statistical studies with his early depictions of the Mudfog Association in Sketches by Boz (1833-36) and later in Hard Times (1854). The Mudfog Association's self-important and pointlessly detailed statistical reports, and Sissy Jupe's inability to comprehend, much less to pronounce, the term held dear by the unforgivingly utilitarian Gradgrind and the schoolmaster M'Choakumchild, asserted the emptiness and meaninglessness of statistical inquiry in comparison with what Dickens's novels celebrated: individuals, families, daily lives, and domestic feeling. But the author of this essay, expressing at once a specu
Inhibitory Effects of Rosemary Oil on the In Vitro Growth of Six Common Finfish Pathogens

Abstract Additives are commonly used in feed to enhance fish performance, health, and well-being. In recent years, antibiotics have received increased scrutiny owing to concerns about overuse and their environmental impact. These concerns have generated a desire for naturally derived alternatives for the aquafeed industry. For screening purposes, we examined the in vitro effects of an essential oil on bacteria commonly associated with fish diseases. Six concentrations of rosemary Rosmarinus officinalis oil (0.1, 0.3, 0.5, 0.7, and 0.9 μL/μL of 1% Tween-20 and pure rosemary oil [1.0]) were used against Flavobacterium psychrophilum, Yersinia ruckeri, Aeromonas salmonicida, and three warmwater bacterial pathogens, A. hydrophila, Edwardsiella ictaluri, and E. tarda, along with a control treatment (1% Tween-20 only). After incubation, the mean zone of inhibition around the disks was measured. While most concentrations were found to inhibit pathogen growth, a concentration of 50% or more was found to have signi...
A new quasi-optical filter: the reflective polarizing interferometer

A new type of optical filter element has been described and tested, offering an alternative frequency response to that of a Fabry-Perot or Michelson interferometer. It is quite compact, mechanically stable, and suitable for cryogenic operation. Use of this device is planned as a sideband filter in a 15 element imaging array receiver for 90–115 GHz.
Left parotid mass in a 71-year-old woman.

CASE PRESENTATION In October 2012, a 70-year-old black woman presented to her ophthalmologist, who noted that she had a left parotid mass. She was subsequently referred to a hospital to have the mass evaluated. It was unclear how long the mass was present, but there were no symptoms. The patient reported no family history of malignancy, and her health was significant for type 2 diabetes mellitus, non-insulin-dependent. The patient had smoked 2 packs a day for 22 years, but she stated that she had quit 40 years ago. She stated she drank 1 to 2 alcoholic beverages per month. At an outside hospital, ultrasonography found a heterogeneously hypoechoic mass with irregular margins containing focal necrosis with possible deep extracapsular extension measuring 1.96 2.49 cm. No increased flow signal was seen on Doppler mode. A fine-needle aspiration (FNA) of the parotid mass was suspicious for acinic cell carcinoma. Within the same month, the patient was sent to Memorial Sloan Kettering Cancer Center. A computed tomography (CT) scan of the neck found an ill-defined, enhancing soft tissue mass in the left parotid tail with no deep parotid involvement, measuring 2.3 1.9 2.0 cm (Figure 1). No abnormal lymphadenopathy was noted in the neck. A second FNA taken of the left parotid found a salivary gland neoplasm with a cylindromatous pattern, which favored pleomorphic adenoma (Figure 2). The FNA slides from the previous hospital were also reviewed, and ultimately the diagnoses encompassed a differential diagnosis that included both acinic cell carcinoma and pleomorphic adenoma. A positron emission tomographyecomputed tomography scan found a 1.3 1.5-cm left parotid nodule with a maximum standardized uptake value of 2.7 (Figure 3). No hypermetabolic lymphadenopathy was noted in the neck.
Combined rapid maxillary expansion and protraction facemask in the treatment of class III malocclusions in growing children: A prospective long-term study

A prospective study of 28 growing children (mean age of 8 years 3 months) with Class III malocclusions was consecutively treated using rapid maxillary expansion and maxillary protraction. All patients were treated from a negative overjet to a positive overjet and from a Class III dental malocclusion to a Class I dental relationship. For each patient, a lateral cephalogram was taken before treatment (T1), immediately posttreatment (T2), and after an observation period (T3) averaging 2 years 5 months. Using analysis of variance, the cephalograms were analyzed to determine skeletal and dental changes resulting from treatment. Long-term changes (2 years 5 month observation period) were also evaluated. Results showed that immediately posttreatment, the maxilla moved anteriorly a mean of 1.54 mm and Sella-Nasion-A point increased 0.87 degree. The maxillary teeth moved anteriorly 2.73 mm and proclined 5.23 degrees, while the mandible rotated in a downward and backward direction. Long-term, the anterior position of the maxilla was maintained, but some of the Class III correction was lost because of mandibular growth. Comparison of this study's results to Riolo's longitudinal Class I data showed that, overall, rapid palatal expansion and maxillary protraction produced a small orthopedic effect with a moderate dentoalveolar effect which together contributed to the correction of the Class III malocclusion.
Holmium : YAG laser endoscopic sinus surgery : a randomized, controlled study

Although surgical lasers were introduced to the field of otolaryngology more than 20 years ago, their use in rhinologic surgery has remained relatively limited. With the development of the holmium:yttrium-aluminum-garnet (YAG) laser, a device is now available that offers those features necessary for effective sinus surgery:precise bone ablation, efficient soft tissue coagulation, and fiberoptic transmission. This solid-state laser of 2.1-microns wavelength can be coupled with endoscopic instrumentation for the surgical treatment of sinus disease. This study was conducted to determine the clinical efficacy of the holmium:YAG laser for endoscopic sinus surgery. A microscopic analysis of laser-treated sinus tissue was also performed in an attempt to determine the histologic basis of the observed clinical findings. In a prospective, randomized, controlled, single-blinded study, 32 consecutive patients underwent endoscopic sinus surgery using the holmium:YAG laser on one side of the nose and conventional endoscopic instrumentation on the other side. Patients rated symptoms for each side of the nose at 1 week, 1 month, 3 months, 6 months, and 2 years after surgery. Healing parameters were similarly rated by the surgeon. Until the study was completed, patients were not told which side of the nose had been treated with laser surgery. No intraoperative complications occurred. The mean intraoperative blood loss was 24.6 mL less on the laser-treated side of the nose than on conventionally treated side (P < .001). At 1 week after surgery, there was increased mucosal edema on the laser-treated side (P < .01). Crust formation was greater on the conventionally treated side at 1 week and was greater on the laser-treated side at 1 mouth (P < .01). Improvements in symptoms of pain, congestion, and drainage were equivalent for both treatment modalities (P < .001). Microscopic analysis demonstrated the ability of the holmium:YAG laser to remove tissue in relatively thin layers with ablation depths of 260 +/- 8.2 microns, 286 +/- 9.4 microns, and 341 +/- 20.4 microns per pulse at energy levels of 0.5, 1.0, and 1.5 J, respectively. A zone of thermal necrosis extending up to 1 mm beyond the site of laser impact was thought to correlate with the increased postoperative edema observed on the laser-treated side. Endoscopic sinus surgery with the holmium:YAG laser is as effective as nonlaser techniques in relieving the symptoms of chronic sinusitis. Laser surgery offers improved intraoperative hemostasis, but it causes increased postoperative tissue edema. The holmium:YAG laser provides the surgeon with an additional tool for the performance of safe, effective sinus surgery.
β-tting on p63 as a Metastatic Suppressor

Although much is known about the genes that promote metastasis, few suppressors of metastasis have been found. Adorno et al. (2009) now identify p63 as a potent suppressor of metastasis and uncover an intricate mechanism for the inactivation of metastasis in cancer cells in response to transforming growth factor β.
A Review of Stream Restoration Techniques and a Hierarchical Strategy for Prioritizing Restoration in Pacific Northwest Watersheds

Abstract Millions of dollars are spent annually on watershed restoration and stream habitat improvement in the U.S. Pacific Northwest in an effort to increase fish populations. It is generally accepted that watershed restoration should focus on restoring natural processes that create and maintain habitat rather than manipulating instream habitats. However, most process-based restoration is site-specific, that is, conducted on a short stream reach. To synthesize site-specific techniques into a process-based watershed restoration strategy, we reviewed the effectiveness of various restoration techniques at improving fish habitat and developed a hierarchical strategy for prioritizing them. The hierarchical strategy we present is based on three elements: (1) principles of watershed processes, (2) protecting existing high-quality habitats, and (3) current knowledge of the effectiveness of specific techniques. Initially, efforts should focus on protecting areas with intact processes and high-quality habitat. Fol...
Career of the medalist

IT WAS with some hesitation that I accepted the privilege of presenting a resume of the career of the Medalist because I am certain of a number of men who have been more intimately associated than I with Dr. Kilgore's most recent engineering contributions. Still, in respect and admiration for his over-all accomplishments I can yield to none and, therefore, shall seek to refresh the memories of a few and to set forth for others some of his work leading up to this present event.
Thoracoscopic repair of esophageal atresia with distal tracheoesophageal fistula and a proximal type-H tracheoesophageal fistula

Abstract The purpose of this study was to report a combined approach using thoracoscopy and flexible bronchoscopy to identify and repair a rare tracheoesophageal fistula (TEF) anatomic variant. This variant had both a distal tracheoesophageal fistula and a rare proximal fistula in an H-type configuration located high in the thoracic inlet. A 2045 g, ex-35 week female underwent thoracoscopy for what was preoperatively believed to be Gross type C anatomy. After ligation of the distal fistula, ventilation remained challenging and intraoperative flexible bronchoscopy revealed a proximal fistula. The proximal fistula was in a H-type configuration high in the thoracic inlet. Both fistulae, as well as the esophageal atresia, were repaired thoracoscopically. A postoperative contrast study at 10 days and 3 months revealed an intact esophageal repair without a leak or stricture. A postoperative rigid bronchoscopy at 10 days showed no airway abnormalities. A narrated video of the operation is available under the supplemental data of this publication. The thoracoscopic repair of this rare tracheoesophageal fistulae variant with H-type anatomy between the proximal pouch and trachea located high in the thoracic inlet is feasible in low birth weight infants. Intraoperative flexible bronchoscopy is a valuable tool for the identification of a second fistula.
A long-lasting concentration cell based on a magnetic electrolyte

A concentration cell is composed of two equivalent half-cells made of the same material but differing in the concentration of reactants. As these concentrations equilibrate, the increase in entropy is converted into a flow of electricity with the voltage output determined by the Nernst equation and proportional to the logarithm of the concentration ratios. However, as diffusion constantly strives to erase all concentration gradients, concentration cells produce only moderate voltages (typically tens of millivolts at room temperature) over relatively short times and, consequently, such devices have not been regarded as promising for energy storage. Here, we report a concentration cell that produces significantly higher voltages (∼ 0.5 V) for over 100 h. The key to our design is that the citric acid molecules involved in the electrode reactions are tethered onto magnetic nanoparticles, and a sharp gradient (10(7)-10(11) anode/cathode concentration ratio) is maintained at one of the electrodes by a permanent magnet external to the cell. Our cell does not result in corrosion of the electrodes, produces no harmful by-products, and can be regenerated by recoating used nanoparticles with fresh citric acid. We show that a series of such centimetre-sized cells produces enough electricity to power small electronic devices (timers and calculators) for several tens of hours. Our results illustrate how redox-active molecules that are, in themselves, non-magnetic can be effectively concentrated by magnetic fields to produce electrical energy.
Safety Climate and Medical Errors in 62 US Emergency Departments

Study objective We describe the incidence and types of medical errors in emergency departments (EDs) and assess the validity of a survey instrument that identifies systems factors contributing to errors in EDs. Methods We conducted the National Emergency Department Safety Study in 62 urban EDs across 20 US states. We reviewed 9,821 medical records of ED patients with one of 3 conditions (myocardial infarction, asthma exacerbation, and joint dislocation) to evaluate medical errors. We also obtained surveys from 3,562 staff randomly selected from each ED; survey data were used to calculate average safety climate scores for each ED. Results We identified 402 adverse events (incidence rate 4.1 per 100 patient visits; 95% confidence interval [CI] 3.7 to 4.5) and 532 near misses (incidence rate 5.4 per 100 patient visits; 95% CI 5.0 to 5.9). We judged 37% of the adverse events, and all of the near misses, to be preventable (errors); 33% of the near misses were intercepted. In multivariable models, better ED safety climate was not associated with fewer preventable adverse events (incidence rate ratio per 0.2-point increase in ED safety score 0.82; 95% CI 0.57 to 1.16) but was associated with more intercepted near misses (incidence rate ratio 1.79; 95% CI 1.06 to 3.03). We found no association between safety climate and violations of national treatment guidelines. Conclusion Among the 3 ED conditions studied, medical errors are relatively common, and one third of adverse events are preventable. Improved ED safety climate may increase the likelihood that near misses are intercepted.
Postbuckling behavior of longitudinally compressed orthotropic plates with transverse shearing flexibility

The buckling results have been plotted to show the effects of thickness on the stress coefficient for aluminum plates. Postbuckling results for thin plates with transverse shearing flexibility are compared to results from classical theory. The plates are considered to be long with side edges simply supported, with various in-plane edge conditions, and the plates are subject to a longitudinal compressive displacement. Characteristic curves presenting the average longitudinal direct-stress resultant as a function of the applied displacement are given
Barone's 1908 representation of an economy's trade equilibrium and the gains from trade

John Chipman's 1965 ‘Survey of the theory of international trade’ implied that Enrico Barone arrived in 1920–23 at an analytical representation of an economy's trading equilibrium. In fact, the latter appeared in a long footnote (here translated) found in the original 1908 edition of Barone's Principi di Economia Politica. The three diagrams accompanying it completely represent an economy's equilibrium in autarky and in trade, and its gains from trade. Thus, Barone can claim precedence (by over twenty years) over Haberler, Lerner, Leontief and Viner as the originator of the neoclassical model of an open trading economy and its diagrammatic representation.
Statistical Static Timing Analysis Considering the Impact of Power Supply Noise in VLSI Circuits

As semiconductor technology is scaled and voltage level is reduced, the impact of power supply variation has become very significant in predicting the realistic worst-case delays in integrated circuits. The analysis of power supply noise is inevitable since there is a high correlation between delay and supply voltage. Supply noise analysis has often used a vector-based STA approach. However, vector-based approaches are very expensive, particularly during the design phase. In this work, two novel vectorless approaches are described such that circuit delay increases due to power supply noise can be efficiently estimated. Experimental results on ISCAS89 circuits show not only the accuracy of our approaches, but also the indispensability of considering care-bits, which sensitize the longest paths during the power supply noise analysis.
GPU-accelerated volume splatting with elliptical RBFs

Radial Basis Functions (RBFs) have become a popular rendering primitive, both in surface and in volume rendering. This paper focuses on volume visualization, giving rise to 3D kernels. RBFs are especially convenient for the representation of scattered and irregularly distributed point samples, where the RBF kernel is used as a blending function for the space in between samples. Common representations employ radially symmetric RBFs, and various techniques have been introduced to render these, also with efficient implementations on programmable graphics hardware (GPUs). In this paper, we extend the existing work to more generalized, ellipsoidal RBF kernels, for the rendering of scattered volume data. We devise a post-shaded kernel-centric rendering approach, specifically designed to run efficiently on GPUs, and we demonstrate our renderer using datasets from subdivision volumes and computational science.
Infusing software engineering technology into practice at NASA

We present an ongoing effort of the NASA Software Engineering Initiative to encourage the use of advanced software engineering technology on NASA projects. Technology infusion is in general a difficult process yet this effort seems to have found a modest approach that is successful for some types of technologies. We outline the process and describe the experience of the technology infusions that occurred over a two year period. We also present some lessons from the experiences.
Project-Level Assessment of Environmental Impact: Ecosystem Services Approach to Sustainable Management and Development

Project firms currently have little incentive to incorporate environmental considerations into infrastructure development or management decisions beyond those that are either regulated or subject to public perception. This lack of incentive exists in part owing to the absence of: (1) a clear understanding of the connections between project ecological affects and how these damage firm/project assets; and (2) the ability to include the project ecological effects in operational decisions. In response, the concept of ecosystem service monetization is applied as a novel approach to capitalize on the relationship between industry and the natural environment. We present a framework for ecosystem service valuation that consists of four parts: (1) life cycle assessment (LCA) to quantify project ecosystem emissions; (2) fundamental biophysics and biochemistry to characterize the component processes of ecosystem services; (3) functional substitutability to assign a monetary value to such services; and (4) representa...
Isolation of deer tick virus (Powassan virus, lineage II) from Ixodes scapularis and detection of antibody in vertebrate hosts sampled in the Hudson Valley, New York State

Deer tick virus, DTV, is a genetically and ecologically distinct lineage of Powassan virus (POWV) also known as lineage II POWV. Human incidence of POW encephalitis has increased in the last 15 years potentially due to the emergence of DTV, particularly in the Hudson Valley of New York State. We initiated an extensive sampling campaign to determine whether POWV was extant throughout the Hudson Valley in tick vectors and/or vertebrate hosts. More than 13,000 ticks were collected from hosts or vegetation and tested for the presence of DTV using molecular and virus isolation techniques. Vertebrate hosts of Ixodes scapularis (black-legged tick) were trapped (mammals) or netted (birds) and blood samples analyzed for the presence of neutralizing antibodies to POWV. Maximum likelihood estimates (MLE) were calculated to determine infection rates in ticks at each study site. Evidence of DTV was identified each year from 2007 to 2012, in nymphal and adult I. scapularis collected from the Hudson Valley. 58 tick pools were positive for virus and/or RNA. Infection rates were higher in adult ticks collected from areas east of the Hudson River. MLE limits ranged from 0.2-6.0 infected adults per 100 at sites where DTV was detected. Virginia opossums, striped skunks and raccoons were the source of infected nymphal ticks collected as replete larvae. Serologic evidence of POWV infection was detected in woodchucks (4/6), an opossum (1/6), and birds (4/727). Lineage I, prototype POWV, was not detected. These data demonstrate widespread enzootic transmission of DTV throughout the Hudson Valley, in particular areas east of the river. High infection rates were detected in counties where recent POW encephalitis cases have been identified, supporting the hypothesis that lineage II POWV, DTV, is responsible for these human infections.
Cytokeratin 7 negative invasive breast carcinoma: clinicopathological and immunohistochemical analysis of 14 cases with clinical follow-up.

Cytokeratin 7 (CK 7) negative breast tumours are reported to occur rarely. We studied 14 CK 7 negative cases of primary invasive ductal carcinoma (IDC) detected during sentinel lymph node metastases work-up and immunohistochemistry panel in the work-up of metastatic carcinoma of unknown origin. Axillary lymph node metastases were present in seven patients (50%). Oestrogen receptor (ER) was strongly positive in all cases: progesterone receptor in 78%, Her-2/neu in 7% and high proliferation index with Ki-67 >20% was seen in 71% of the cases. Metastatic and/or recurrence were found in 8 of 14 patients (57%) with the mean clinical follow-up of 55 months. Metastatic sites include multiple bones, brain, spinal cord, liver, pancreas, ovary, lung, lymph node other than ipsilateral axillary and skin. 12 of 14 patients received adjuvant chemotherapy. All 14 patients received hormonal therapy and radiation therapy. Morphologically, IDC with neuroendocrine features was noted in 57%. Synaptophysin stain was positive in 57% and chromogranin was positive in 21% of the cases. In conclusion, these CK 7 negative breast carcinomas were ER positive, mostly Her-2/neu negative, had high Ki-67 and frequently showed neuroendocrine differentiation. More than half of these cases had a poor outcome.
A hierarchical modeling methodology for flexible manufacturing systems using extended Petri nets

A theory of extended Petri nets is proposed to enable the modeling of flexible manufacturing systems in a more comprehensive manner. The theory considers both the flow of control and flow of information, resources and parts in a system. A methodology for hierarchically modeling manufacturing systems using extended Petri net techniques, to ensure a priori the desirable properties of system performance is presented. The approach is based on modular modeling. >
Mechanized Agriculture and Social Welfare: The Case of the Tomato Harvester

An integrated public-private approach to mechanical harvesting of tomatoes for canning has sharply reduced producers ' labor requirements. Gross social returns to aggregate research and development expenditures are in the vicinity of 1,000 percent. Even if displaced labor had been compensated for wage loss, net social returns are still highly favorable. Since tomato pickers were unorganized, no compensation was demanded or paid. The analysis indicates a need for policies designed to distribute the benefits and costs of technological change more equitably. Social scientists could properly be concerned with developing institutional means of achieving this goal.
Synthesis and characterization of fivefold twinned nanorods and right bipyramids of palladium

This Letter describes the first synthesis of fivefold twinned nanorods and right bipyramids of palladium in an aqueous solution, with ascorbic acid as a reducing agent and in the presence of bromide. Like the silver system, these two types of nanostructures are derived from multiple and single twinned seeds, respectively. The ascorbic acid, bromide, and reaction temperature all play important roles in the synthesis.

Examining developmental differences in the social‐emotional problems among frequent bullies, victims, and bully/victims

Bullying poses a threat to children's social-emotional functioning and their perceptions of school climate, yet few studies have examined different types of social-emotional and behavior problems presented by children involved in bullying, as a bully, victim, or bully/victim across multiple school levels. The current study used data from 24,345 elementary-, middle-, and high-school students to examine the association between frequent involvement in bullying and aggressive impulsivity, attitudes toward aggressive retaliation, internalizing symptoms, peer relations, and perceptions of school climate. Logistic regression analyses indicated that bully/victims were most likely to display internalizing symptoms, problems in peer relationships, and have poorer perceptions of the school environment. Both frequent bullies and bully/victims displayed aggressive-impulsive behavior and endorsed retaliatory attitudes. High-school students frequently involved in bullying tended to display the greatest risk for internalizing problems, but less risk for aggressive impulsivity. Developmental trends and implications for prevention and early intervention are discussed. © 2008 Wiley Periodicals, Inc.
High-dose intravenous pulse methylprednisolone hemisuccinate in acute behçet retinitis

Purpose To report the response of acute Behcet retinitis to high-dose corticosteroids. Method Case report. A 58-year-old man with Behcet disease and severe bilateral glaucoma experienced a sudden decrease of visual acuity to counting fingers in his (better-seeing) left eye. Examination disclosed hypopyon uveitis and an infiltrative retinitis threatening the fovea. He received intravenous methylprednisolone hemisuccinate, 1 gram per hour on each of 3 successive days, followed by oral prednisone and cyclosporine. Results The retinal infiltrate disappeared within 24 hours. Visual acuity improved to LE, 20/400 by day 5 and returned to LE, 20/30 after 3 months. A visual field demonstrated a scotoma corresponding to the location of the previous retinitis. Conclusion High-dose intravenous methylprednisolone can reverse severe vision loss in acute Behcet retinitis.
THE CELLULAR ORIGIN OF HUMAN IMMUNOGLOBULINS (γ2, γ1M, γ1A)

A study was made of the cellular origin of human immunoglobulins (γ2, γ1M, γ1A). The results indicated that two closely related families of cells form immunoglobulins in human lymphoid tissue: germinal (reticular) centers and plasma cells. Thus their cellular origin in addition to their known antigenic relations further justifies placing the immunoglobulins in one family of proteins. Immunoglobulins were also formed to a small extent in primitive reticular cells which resembled those of germinal centers but were separated from them. Possibly such cells were undergoing transition to the much more numerous plasma cells with which they were commonly associated. The mantles of small lymphocytes which surrounded germinal centers did not contain detectable quantities of immunoglobulins. While in general only one type of immunoglobulin was present in an individual cell or germinal center, γ2- and γ1M-globulin were identified on occasion in the same plasma cell and germinal center. A peculiarity of the fetal thymus gland was the presence of immunoglobulin, mainly γ1M, in a small number of cells of small and intermediate size and primitive reticular appearance and in Hassall's corpuscles.
Pussy Rioting: THE NINE LIVES OF THE RIOT GRRRL REVOLUTION

This essay explores the evolution of the Riot Grrrl movement. A feminist punk movement that profoundly impacted popular culture in the West during the 1990s, Riot Grrrl is generally regarded as an important but short-lived phenomenon. This paper explores the political relevance of Riot Grrrl within both feminism and popular culture, but also debunks the myth that Riot Grrrl faded away by the turn of the century. Exploring specific cases in Russia and Indonesia, the paper illustrates the ways in which Riot Grrrl has become a global movement and remains active today, influencing people's subjectivity and agency, helping transform people from passive consumers to active feminist cultural producers.
Reciprocal relationships in viscous hydrodynamics

Reciprocal relationships are derived for the basic physical problem of a rigid body which translates with constant velocity through a viscous incompressible fluid of infinite extent. In addition to this basic situation, further allowances are made for rotational, magnetic, and thermal effects, as well as a restricted type of time dependence. The reciprocal relationships involve the net fluid force exerted on the moving body and the net heat flux through its surface. The most interesting result concerns invariance of the drag when the body motion is reversed, independent of any symmetry.

Investigation of living quality of employees in public places and influential factors

Objective To investigate living quality and its influencing factors of employees in public places,and provide a scientific evidence for interventions to improve employees' life quality.Methods Custer sampling method was used to select employees in public places which had carried out monitoring in 2012.Questionnaire survey was carried out by the World Health Organization Quality of Life Scale(WHOQOL-BREF) Chinese version to examine life quality.Results Average score of subjective life quality,subjective overall health,physiological field,psychological field,social relationship field and environmental field were 3.57,3.67,14.65,13.62,14.42 and 12.64 respectively.The physiological field score was significantly lower than the norm,and social relationship field and environmental field score was significantly higher than the norm(P0.01).Univariate analysis showed that education background,health status,profession,monthly income and housing area per capital were influential factors of physiological field,while multiple regression analysis showed that family frictions,appetite and education background were influential factors.Conclusion Life quality of employees in public places was acceptable,but the physiological field score was lower than the general population.It should be take appropriate measures to improve employees' quality of life.
Development and Validation of an Instrument Measuring Theory-Based Determinants of Monitoring Obesogenic Behaviors of Pre-Schoolers among Hispanic Mothers

Public health interventions are greatly needed for obesity prevention, and planning for such strategies should include community participation. The study’s purpose was to develop and validate a theory-based instrument with low-income, Hispanic mothers of preschoolers, to assess theory-based determinants of maternal monitoring of child’s consumption of fruits and vegetables and sugar-sweetened beverages (SSB). Nine focus groups with mothers were conducted to determine nutrition-related behaviors that mothers found as most obesogenic for their children. Next, behaviors were operationally defined and rated for importance and changeability. Two behaviors were selected for investigation (fruits and vegetable and SSB). Twenty semi-structured interviews with mothers were conducted next to develop culturally appropriate items for the instrument. Afterwards, face and content validity were established using a panel of six experts. Finally, the instrument was tested with a sample of 238 mothers. Psychometric properties evaluated included construct validity (using the maximum likelihood extraction method of factor analysis), and internal consistency reliability (Cronbach’s alpha). Results suggested that all scales on the instrument were valid and reliable, except for the autonomy scales. Researchers and community planners working with Hispanic families can use this instrument to measure theory-based determinants of parenting behaviors related to preschoolers’ consumption of fruits and vegetables, and SSB.
The Severity of Bleeding and Mortality in Trauma Patients Taking Dabigatran

Abstract Background Dabigatran, a direct thrombin inhibitor, has been shown to be more effective than warfarin in the prevention of stroke in patients with atrial fibrillation. Until recently, it lacked a reversal agent, and its contribution to the risk of transfusion in injured patients is unknown. Objective We sought to determine whether patients who sustain traumatic injuries while taking dabigatran receive more blood transfusions than matched patients taking warfarin, aspirin, clopidogrel, or controls. Methods This retrospective, single-center cohort consisted of injured patients who were taking dabigatran before admission to a major trauma center (January 2010–December 2013) who were compared with cohorts of patients taking warfarin, clopidogrel, or aspirin and a control group. The outcome was bleeding risk as measured by the use of blood products, with mortality as a secondary outcome. Outcomes were controlled for by age, sex, injury severity, and blunt mechanism. Results Thirty-eight patients were taking dabigatran. Compared with the general trauma population, patients taking dabigatran were more likely to be male, older, and to have higher injury severity. Patients taking dabigatran received transfusions (odds ratio [OR] 1.31 [95% confidence interval {CI} 0.56–3.04]), packed red blood cells (OR 1.43 [95% CI 0.54–3.77]), frozen plasma (OR 1.20 [95% CI 0.42–3.49]), and platelets (OR 2.01 [95% CI 0.63–6.37]) as often as matched controls. The mortality rate among patients on dabigatran was 12.5% (OR 1.51 [95% CI 0.39–5.89]) compared with 9.1% in matched controls. None of these results was statistically significant. Conclusions In this small study, injured patients taking dabigatran were transfused as often and had similar in-hospital mortality as matched controls who were not taking anticoagulants.
Mechanistic Evaluation of LixOy Formation on δ-MnO2 in Nonaqueous Li–Air Batteries

Transition metal oxides are usually used as catalysts in the air cathode of lithium–air (Li–air) batteries. This study elucidates the mechanistic origin of the oxygen reduction reaction catalyzed by δ-MnO2 monolayers and maps the conditions for Li2O2 growth using a combination of first-principles calculations and mesoscale modeling. The MnO2 monolayer, in the absence of an applied potential, preferentially reacts with a Li atom instead of an O2 molecule to initiate the formation of LiO2. The oxygen reduction products (LiO2, Li2O2, and Li2O molecules) strongly interact with the MnO2 monolayer via the stabilization of Li–O chemical bonds with lattice oxygen atoms. As compared to the disproportionation reaction, direct lithiation reactions are the primary contributors to the stabilization of Li2O2 on the MnO2 monolayer. The energy profiles of (Li2O2)2 and (Li2O)2 nucleation on δ-MnO2 monolayer during the discharge process demonstrate that Li2O2 is the predominant discharge product and that further reduction ...
Permanent Deacons and Non-profit Directors: Comparing Leadership Styles Among Facilitators of Community Agencies

Permanent deacons in the Roman Catholic Church (all male) are active in their local community and congregation mobilizing faith formation events, liturgical services, and community social action programs, yet not much is known about their leadership style. The present study compared U.S. 203 permanent deacons with 202 male community-based directors of non-profit agencies on their self-reported transformational leadership style, assessed by five subscales of competencies. Deacons and directors differed significantly on three subscales; deacons scored higher on the promoting positive values and leadership as service subscales, while directors scored higher on the building a sustainable organization subscale. Results suggested that the transformational leadership styles of U.S. permanent deacons is more value and service-centered, and, in comparison, community-based non-profit leaders seem to focus more on the group’s structure and health of their organization.
Polarization Options and Terminal Area Multifunction Radars

Multifunction skin track radars utilizing phased array technologies are being considered for terminal area air traffic control surveillance. Augmenting the preferred cooperative beacon-based system, these skin track radars would provide detection and tracking of uncooperative intruders in the terminal area airspace, continued surveillance on any aircraft experiencing a transponder failure, and detection and real-time tracking of potentially hazardous weather cells. An operational limitation on the use of skin track radar is the difficulty in detecting the presence of an aircraft in a range cell that also contains rain clutter. This target to background contrast may be improved by use of circular polarization. The degree of improvement depends upon the rain cancellation ratio and the incremental reduction in aircraft backscatter cross section when viewed with circular polarization. It has also been suggested that alternate use of vertical and horizontal linear polarization could indicate the presence of ha...
Using Active Learning Activities to Increase Student Outcomes in an Information Technology Course

ABSTRACTThe goal of higher education to produce well-rounded and critically thinking problem solvers to enter into the hospitality industry remains a crucial area of research for hospitality educators. To support this goal, numerous hospitality scholars have engaged in innovative approaches to classroom instruction that facilitate problem solving and critical thinking. Grounded in the principles of the constructivist theory of learning, this study furthers understanding of how to produce these results by using mobile technology within a flipped classroom. Approximately 230 undergraduate students were evaluated using a freshman course redesigned from a predominantly lecture-based one to one that utilized active learning activities. The results showed improvements in technical skills, leadership, teamwork, communication, openness to diversity, and creativity.
Integrated microRNA and mRNA network analysis of the human myometrial transcriptome in the transition from quiescence to labor.

We conducted integrated transcriptomics network analyses of miRNA and mRNA interactions in human myometrium to identify novel molecular candidates potentially involved in human parturition. Myometrial biopsies were collected from women undergoing primary Cesarean deliveries in well-characterized clinical scenarios: (1) spontaneous term labor (TL, n = 5); (2) term nonlabor (TNL, n = 5); (3) spontaneous preterm birth (PTB) with histologic chorioamnionitis (PTB-HCA, n = 5); and (4) indicated PTB nonlabor (PTB-NL, n = 5). RNAs were profiled using RNA sequencing, and miRNA-target interaction networks were mined for key discriminatory subnetworks. Forty miRNAs differed between TL and TNL myometrium, while seven miRNAs differed between PTB-HCA vs. PTB-NL specimens; six of these were cross-validated using quantitative PCR. Based on the combined sequencing data, unsupervised clustering revealed two nonoverlapping cohorts that differed primarily by absence or presence of uterine quiescence, rather than gestational age or original clinical cohort. The intersection of differentially expressed miRNAs and their targets predicted 22 subnetworks with enriched representation of miR-146b-5p, miR-223-3p, and miR-150-5p among miRNAs, and of myocyte enhancer factor-2C (MEF2C) among mRNAs. Of four known MEF2 transcription factors, decreased MEF2A and MEF2C expression in women with uterine nonquiescence was observed in the sequencing data, and validated in a second cohort by quantitative PCR. Immunohistochemistry localized MEF2A and MEF2C to myometrial smooth muscle cells and confirmed decreased abundance with labor. Collectively, these results suggest altered MEF2 expression may represent a previously unrecognized process through which miRNAs contribute to the phenotypic switch from quiescence to labor in human myometrium.Summary SentenceIntegrated miRNA–mRNA study in human myometrium.
Enhanced Ion Adsorption on Mineral Nanoparticles

Classical molecular dynamics simulation was used to study the adsorption of Na+, Ca2+, Ba2+, and Cl– ions on gibbsite edge (1 0 0), basal (0 0 1), and nanoparticle (NP) surfaces. The gibbsite NP consists of both basal and edge surfaces. Simulation results indicate that Na+ and Cl– ions adsorb on both (1 0 0) and (0 0 1) surfaces as inner-sphere species (i.e., no water molecules between an ion and the surface). Outer-sphere Cl– ions (i.e., one water molecule between an ion and the surface) were also found on these surfaces. On the (1 0 0) edge, Ca2+ ions adsorb as inner-sphere and outer-sphere complexes, whereas on the (0 0 1) surface, outer-sphere Ca2+ ions are the dominant species. Ba2+ ions were found as inner-sphere and outer-sphere complexes on both surfaces. Calculated ion surface coverages indicate that, for all ions, surface coverages are always higher on the basal surface compared to those on the edge surface. More importantly, surface coverages for cations on the gibbsite NP are always higher tha...
Lonesome Road Blues

Used condoms, beer bottles, wire, broken glass, a girl's t-shirt torn and snagged in a tree. Deserted roads lure dead diversions: grass groping its way through the cracks, a dropped key coughed up from the damp mud of a dank ditch. See? Here, dried blood still paints a few fence posts, and beneath the rotted railroad bridge which shores up the darkness, a patrolman hopes the battered body floating in the mist isn't the Gann girl still missing for weeks. Her boyfriend ignores the pain in his wrists as handcuffed he stumbles down to the creek, his eyes fixed, the tune he hums low and sad, Going down the road feeling bad, bad, bad.
