A Survey Comparing Special Education Services for Students with Disabilities in Rural Faith-Based and Public School Settings

This descriptive study examined the provision of special education services in faith-based schools, especially as compared to public schools. A survey was used to collect information about the special education services typically provided to students with mild disabilities in faith-based schools. Information was also gathered about teacher qualifications and instructional activities of special education teachers in faith-based schools. The same information was gathered on a matched sample of public schools. The results indicated that for this sample, most faith-based schools provided some level of special education services to students with mild disabilities and used some special education services provided by public schools. There were clear differences between the public and faith-based schools in this study, including (a) fewer students with identified disabilities in faith-based schools, (b) less special education training for the special education teachers in faith-based schools, and (c) less use of certain related services, such as physical therapy.
Nebivolol Induces Nitric Oxide Release in the Heart Through Inducible Nitric Oxide Synthase Activation

Nebivolol is a β1-adrenergic receptor antagonist that also reduces blood pressure by evoking endothelial NO production and vasodilation. We aimed at assessing whether nebivolol induces NO production also in the heart and delineating the molecular mechanisms involved. Using the fluorescent probe diaminofluorescein, we found that nebivolol induces a dose-dependent NO production in the heart, statistically significant already at 10−7 mol/L. It is not an effect because of the blockade of β1-adrenergic receptor, because this effect is not shared by another drug of the same class, atenolol. Because nebivolol has been reported to act as an agonist on other β-adrenergic receptors, we tested NO production in the presence of receptor antagonists. Nebivolol was not able to induce NO production in presence of the β3-antagonist SR59230A, indicating a fundamental role for β3-adrenergic receptors in cardiac NO production by nebivolol. Moreover, inducible NO synthase inhibition abolishes NO release in the heart, indicating that nebivolol induces NO production by acting on the inducible isoform of the enzyme. The action of nebivolol on inducible NO synthase was confirmed by real-time PCR experiments, showing cardiac overexpression of inducible NO synthase but not neuronal NO synthase or endothelial NO synthase, after 5 hours of treatment with nebivolol. In conclusion, our study demonstrates that nebivolol also stimulates NO production in the heart. This action of nebivolol is exerted via a signaling pathway starting from the activation of β3-adrenergic receptors and leading to overexpression of inducible NO synthase. Cardiac NO production by nebivolol could participate in the cardiovascular effects of nebivolol treatment in patients affected by hypertension and heart failure.
SenseNet : A Linguistic Tool to Visualize Numerical-Valance Based Sentiment of Textual Data

We believe that text is an important modality for human-computer interaction; so studying the relationship between sentiments conveyed through text and natural language by a numerical analysis strategy is worthwhile for the task of sentiment analysis. Different approaches have already been employed to “sense” sentiment, especially from the texts, but none of those ever considered the valenced based cognitive and appraisal structure of sentiments. The paper puts forward a different approach to sense and visualize sentiments embedded in texts by applying a numerical-valence based analysis. To meet this objective we have developed a linguistic tool called SenseNet to visualize sentiments of input texts.
The Impact of Electronic Medical Records on Hospital-Acquired Adverse Safety Events: Differential Effects Between Single-Source and Multiple-Source Systems

The objective was to examine differential impacts between single-source and multiple-source electronic medical record (EMR) systems, as measured by number of vendor products, on hospital-acquired patient safety events. The data source was the 2009-2010 State Inpatient Databases of the Healthcare Cost and Utilization Project for California, New York, and Florida, and the Information Technology Supplement to the American Hospital Association’s Annual Survey. Multivariable regression analyses were conducted to estimate the differential impacts of EMRs between single-source and multiple-source EMR systems on hospital-acquired patient safety events. In all, 1.98% of adult surgery hospitalizations had at least 1 hospital-acquired patient safety event. Basic EMRs with a single vendor or self-developed EMR systems were associated with a significant decrease in patient safety events by 0.38 percentage point, or 19.2%, whereas basic EMRs with multiple vendors had an insignificant association. A single-source EMR system enhances the impact of EMRs on reducing patient safety events.
25 Gb/s AGC amplifier, 22 GHz transimpedance amplifier and 27.7 GHz limiting amplifier ICs using AlGaAs/GaAs-HEMTs

Automatic-gain-control (AGC), transimpedance, and limiting amplifiers are key elements in optical-fiber links and measuring equipment. This AGC amplifier and transimpedance amplifier are based on 0.3 /spl mu/m gate length HEMTs (f/sub T/=50 GHz). The limiting amplifier uses 0.2 /spl mu/m gate length (f/sub T/= 60 GHz) enhancement (e-mode) and depletion (d-mode) AlGaAs/GaAs HEMTs. The AGC amplifier has 18 GHz bandwidth and 30 dB maximum differential gain with 35 dB dynamic range. The transimpedance amplifier has 22 GHz bandwidth with 76 dB/spl Omega/ gain and the limiting amplifier has 27.7 GHz bandwidth with 26 dB differential gain.

Race, Reform, and Desegregation in Mississippi Higher Education: Historically Black Institutions after United States v. Fordice

In United States v. Fordice (1992), the Supreme Court recognized the effects of past racial discrimination against historically black institutions (HBIs) in Mississippi. One goal of the 500 million settlement is for HBIs to enroll “other-race” students. Although the impetus to attract white students falls on HBIs, the response of Mississippi's white community is pivotal. In a series of focus groups with white students, we inquired into the factors that might motivate them to attend an HBI. The data demonstrate that most white students strongly resist the notion of attending a predominately black institution. They articulate such reasons as perceived poor academic quality, social discomfort, anticipated discrimination, and parental disapproval. Further, they cannot imagine how HBIs might recruit white students and generally doubt that improved programs and facilities would achieve this goal. The current framework surrounding Fordice does not consider sufficiently the importance of these racial attitudes. We thus conclude with a discussion of the likely difficulties in implementing the Court's decision.
On performance analysis of hybrid algorithm (improved PSO with simulated annealing) with GA, PSO for multiprocessor job scheduling

Particle Swarm Optimization is currently employed in several optimization and search problems due its ease and ability to find solutions successfully. A variant of PSO, called as Improved PSO has been developed in this paper and is hybridized with the simulated annealing approach to achieve better solutions. The hybrid technique has been employed, inorder to improve the performance of improved PSO. This paper shows the application of hybrid improved PSO in Scheduling multiprocessor tasks. A comparative performance study is reported. It is observed that the proposed hybrid approach gives better solution in solving multiprocessor job scheduling.
Protein Kinase C in Angiotensin II Signalling in Neonatal Rat Cardiac Fibroblasts

The mitogenic effects of angiotensin II on cardiac fibroblasts are mediated by membrane receptors that are classified as AT1. These receptors are prototypical of the seven transmembrane group of receptors that couple, via G-proteins, to phospholipase C, thereby generating the endogenous activator of protein kinase C, diacylglycerol. Phorbol ester activators of protein kinase C exhibit growth-promoting effects in many cell types, suggesting that this enzyme may be responsible for the growth effects of angiotensin II on cardiac fibroblasts. Both kinase assays and Western analysis demonstrated that angiotensin II does induce translocation of protein kinase C to the detergent-soluble, membrane compartment of cardiac fibroblasts. Although translocation is commonly interpreted to mean activation of protein kinase C, in situ assays on permeabilized cells failed to detect increased enzymatic activity in response to angiotensin II. Nonetheless, this hormone did activate protein kinase C, leading to activation of mitogen-activated protein (MAP) kinases. However, a PKC-independent pathway for activation of MAP kinases exists as well. Downregulation and inhibitor studies indicated that protein kinase C is not critically involved in angiotensin II-induced thymidine incorporation into DNA. Furthermore, phorbol esters that activate protein kinase C do not elicit a mitogenic response in these cells. In conclusion, the mitogenic effects of angiotensin II on cardiac fibroblasts are not simply explained by activation of protein kinase C.
A new, theoretically safer method of intravitreal injection of bevacizumab in progressive retinopathy of prematurity using scleral trans-illumination

Elevated levels of vascular endothelial growth factor (VEGF) drive retinopathy of prematurity (ROP). 1 Laser photocoagulation of avascular retina reduces the risk of severe visual loss, presumably by decreasing VEGF production, but causes loss of peripheral retinal function.2 There has, therefore, been considerable interest in potential application of anti-VEGF agents such as bevacizumab as primary treatment or adjunct to photocoagulation.3 4 However, injections are associated with complications. Anatomical site and vector of injection strongly influence potential for some complications—too posterior risks retinal breaks while too anterior may damage the lens. Despite this, there is no consensus regarding injection site in neonatal patients, with investigators variously administering 0.5–2.0 mm posterior to limbus (table 1). View this table: Table 1 Variations in intravitreal injection procedure between various investigators Ocular trans-illumination studies in adults show two dark bands with an intervening light band—the anterior dark band corresponding …
Low-temperature thermoelectric properties of Zn/Sb thin films prepared by magnetronsputtering

The Zn/Sb multi-layer thin films were prepared by magnetron sputtering method, which was sputtered on (100) Si five times by two single targets. The variations of the Seebeck coefficient, the electric conductivity and the power factor of three Zn/Sb composite films, which was of modulation ratio of 1∶1, 3∶2 and 4∶1 respectively in a fixed modulation period of 40nm, were studied in the temperature range from 160K to 250K. Analyzing the structure and surface appearance by XRD and AFM, the film surface was smooth, dense, and without any macroparticles. The grains of the films grow under the preferred orientations. The experiment results show an obvious trend that the power factor decreases with increasing temperature. The power factor is at the highest value of 7543. 54µW/mK2 in 174K, as the modulation ratio is 4∶1.
Late hepatic allograft dysfunction

Key Points 1 Lifelong monitoring of graft function, immunosuppressive levels, and screening for drug toxicity is required in all liver recipients. 2 Late hepatic allograft dysfunction is common and is caused by a variety of etiologies including rejection, infection, biliary/vascular abnormalities, recurrence of disease, and drug hepatotoxicity. 3 In all patients with late hepatic allograft dysfunction, liver biopsy should be performed to assess for the presence of rejection, and to thus avoid excessive use of bolus corticosteroid therapy and guide appropriate immunosuppressive management. 4 Recurrence of disease is the most common cause of late hepatic allograft dysfunction. 5 Hepatitis C universally reinfects the hepatic allograft, and is associated with decreased patient and graft survival and leads to the recurrence of cirrhosis in 28% of patients within 5 years of transplantation. 6 Major advances have been made in preventing recurrence of hepatitis B by the use of hepatitis B immune globulin in combination with lamivudine therapy. 7 Autoimmune liver diseases such as primary biliary cirrhosis, primary sclerosing cholangitis, and autoimmune hepatitis have a recurrence rate of approximately 20% to 30%. 8 In patients developing recurrence of autoimmune hepatitis, steroid withdrawal is the most common cause. 9 Recurrent hepatocellular cancer can be markedly reduced if strict guidelines are adhered to in selecting patients. 10 Drug hepatotoxicity must always be considered in the differential diagnosis of late hepatic allograft dysfunction.
Emotions during the transition to parenthood among substance-abusing mothers: intensity, content and intervention effects

Objectives: First, to compare multilevel emotion processing (EP) of pregnancy between substance-abusing and non-using women, and, second, to analyse whether different types of interventions can increase positive and functional EP and decrease negative and dysfunctional EP among substance-abusing mothers. EP was conceptualised according to the multifocal theory of emotions proposed by Frijda in 1986, comprising feeling states, behavioural urges to act, cognitive appraisals, and meta-emotions. Method: Participants were 101 women, 51 with substance abuse disorder and 50 comparisons. The substance-abusing women were provided with either intensive psychodynamic mother–infant group therapy (PGT; n = 25) or individually tailored psychosocial support (PSS; n = 26). All women reported their EP once during pregnancy (T1; N = 94), and twice postpartum, when the child was four (T2; N = 84) and twelve (T3; N = 76) months. Results: As hypothesised, the results indicated that the pregnancy-related EP of substance-abusing women was characterised by more negative and fewer positive feeling states, by more intense behavioural urges to act and by lower levels of cognitive appraisals of agency and predictability than the EP of the comparison women. As far as the interventions’ effects on EP, intense behavioural urges to act decreased only in the PGT group, while negative feeling states decreased and agency and predictability appraisals increased from pregnancy to postpartum in the PSS group alone. Conclusions: The importance of helping substance-abusing mothers enhance optimal emotional quality as they prepare for and enter motherhood should be emphasised.
The role of axillary dissection in mammographically detected carcinoma.

BACKGROUND Axillary dissection remains a standard component of the treatment of invasive carcinoma of the breast. The presence of metastases to the regional lymph nodes guides adjuvant therapy and aids in determining prognosis. Mammography results in the discovery of small and often node-negative carcinomas of the breast. STUDY DESIGN This 15-year, retrospective analysis investigated whether certain patients with small tumors could be spared the morbidity of axillary dissection. RESULTS Medical records showed that from January 1980 to May 1995, 4,543 needle localization biopsies were done at York Hospital because of abnormalities detected on mammograms. Of these, 703 (15.5 percent) proved to be carcinoma. Of the carcinomas, 68 percent were infiltrating ductal carcinoma, 26 percent were ductal carcinoma in situ, and 5.4 percent were infiltrating lobular carcinoma. Axillary dissection was done on 588 patients, and 88.1 percent of the patients had no metastases to axillary lymph nodes. No axillary metastases were present in 109 patients with ductal carcinoma in situ who underwent axillary lymph node dissection or in 21 patients with microscopic invasive tumors. Only two of 54 patients with a T1a tumor (tumor [T], < or = 0.5 cm) had positive axillary nodes. Only one of 29 patients with a well-differentiated T1b tumor (T, > 0.5 to < or = 1 cm) had metastatic axillary nodes. In the presence of negative axillary lymph nodes, 19.2 percent of patients with a T1a tumor, 33.7 percent of patients with a T1b tumor, 60 percent of patients with a T1c tumor (T, > 1 to < or = 2 cm), and 78.9 percent of patients with a T2 tumor (T, > 2 cm) were given adjuvant chemotherapy or hormonal therapy. CONCLUSIONS Patients with ductal carcinoma in situ and microscopic invasive tumors do not require node dissections. Possibly patients with T1a tumors and patients with well-differentiated, estrogen-receptor positive, progesterone-receptor positive, T1b tumors can also be spared axillary node dissection. By following this approach on occasion, patients with positive nodes might not undergo axillary lymph node dissection, but they may still be offered adjuvant therapy.
Spontaneous bacterial peritonitis in asymptomatic outpatients with cirrhotic ascites

The prevalence and natural history of spontaneous bacterial peritonitis in asymptomatic patients with ascites secondary to cirrhosis is unknown. From a prospectively recorded database, we reviewed the clinical and laboratory features of all outpatients with cirrhotic ascites undergoing paracentesis between July 1994 and December 2000. The prevalence of spontaneous bacterial peritonitis in the population of 427 cirrhotic outpatients as defined by neutrocytic ascites (absolute neutrophil count ≥250 cells/mm3) was 3.5%. Of the 15 patients with neutrocytic ascites, 6 were culture positive (1.4%) and 9 culture negative (2.1%). Eight other patients (1.9%) had bacterascites. The organisms cultured from ascitic fluid in these asymptomatic patients with culture positive neutrocytic ascites and bacterascites were predominantly gram positive. No patient developed hepatorenal syndrome, and 1‐year survival of 67% was better than historical data from hospitalized patients with spontaneous bacterial peritonitis. Moreover, patients who did not receive antibiotics for neutrocytic ascites fared no worse than patients who did receive antibiotics. In conclusion, spontaneous bacterial peritonitis in outpatients with cirrhotic ascites is less frequent, occurs in patients with less advanced liver disease, and may have a better outcome than its counterpart in hospitalized patients. In addition, the organisms cultured from ascitic fluid in outpatients are predominantly gram positive. A reassessment of diagnostic criteria for spontaneous bacterial peritonitis in outpatients may be required. (Hepatology 2003;37:897‐901.)
Influence of Age, Sex, and Production Class on Liver Zinc Concentration in Calves

Determination of zinc concentrations in the liver of calves and young stock is commonly requested by practitioners and nutritionists to assess whether they receive an appropriate amount of zinc in their diet. However, interpretation of liver zinc concentrations is currently based on information reported for adult cattle for which the health status was unknown and irrespective of production class, sex, and age. A retrospective study of necropsy reports was undertaken to assess the relationships between liver zinc concentrations and age, sex, and production class for calves that did not have a history compatible with zinc toxicosis or zinc deficiency. Results of a generalized least squares, polynomial regression analysis of 474 records found that zinc concentration was not affected by sex (P = 0.29) or production class (P = 0.50). Zinc concentration was significantly associated with linear (P < 0.00001) and nonlinear (quadratic, P = 0.0039) functions of age (r 2 = 0.1503), where the concentration decreased from 93 mg/kg wet weight at 30 days of age to 57 mg/kg wet weight at 9 months of age, after which it began to increase. The age-specific 95% confidence limits of the mean concentration for a group of calves and the 95% prediction limits of a single concentration value for an individual animal estimated in this study suggest reconsideration of the recommended limits for liver zinc concentration in calves. As a consequence of the significant influence of age on liver zinc concentration of calves presumably not experiencing zinc toxicosis or deficiency, diagnosis of zinc imbalances based on liver zinc concentration needs to consider age as a diagnostic covariate.
A longitudinal analysis of achievement goals: From affective antecedents to emotional effects and achievement outcomes.

Affect and emotions are frequently seen as outcomes of mastery and performance goals, but affective experiences may also predict goal adoption. In a predictive study (N = 669 first-year college students), the authors used structural equation modeling to estimate relationships from 2 initial affective experiences to mastery and performance-approach goals, from goals to discrete emotions, and from discrete emotions to final grades in a university course while controlling for prior achievement. Representing initial affective experiences, hopefulness positively predicted mastery and performance goals, whereas helplessness negatively predicted mastery goals. Mastery goals positively predicted enjoyment, which in turn positively predicted achievement, and negatively predicted boredom, which in turn negatively predicted achievement. Anxiety was negatively predicted by mastery goals, positively predicted by performance goals, and exerted a negative predictive influence on achievement. The findings suggest that predictive relationships between goals and achievement are mediated by students' emotions. Results are discussed with regard to the importance of affect and emotions for achievement goal theory.
An Algebra to Merge Heterogeneous Classifiers

In distributed classification, each learner observes its environment and deduces a classifier. As a learner has only a local view of its environment, classifiers can be exchanged among the learners and integrated, or merged, to improve accuracy. However, the operation of merging is not defined for most classifiers. Furthermore, the classifiers that have to be merged may be of different types in settings such as ad-hoc networks in which several generations of sensors may be creating classifiers. We introduce decision spaces as a framework for merging possibly different classifiers. We formally study the merging operation as an algebra, and prove that it satisfies a desirable set of properties. The impact of time is discussed for the two main data mining settings. Firstly, decision spaces can naturally be used with non-stationary distributions, such as the data collected by sensor networks, as the impact of a model decays over time. Secondly, we introduce an approach for stationary distributions, such as homogeneous databases partitioned over different learners, which ensures that all models have the same impact. We also present a method that uses storage flexibly to achieve different types of decay for non-stationary distributions. Finally, we show that the algebraic approach developed for merging can also be used to analyze the behaviour of other operators.
