Perceived transformational teacher leadership and students' motivation, academic performance, and intent to persist in STEM education at a community college

PERCEIVED TRANSFORMATIONAL TEACHER LEADERSHIP AND STUDENTS’ MOTIVATION, ACADEMIC PERFORMANCE, AND INTENT TO PERSIST IN STEM EDUCATION AT A COMMUNITY COLLEGE Stacy Lynn Waters-Bailey Old Dominion University, 2016 Director: Dr. Mitchell Williams The transformational teacher leadership style has been identified as having a positive impact on student motivation, academic performance, and persistence. This study served to determine if there is a relationship between perceived transformational teacher leadership and student motivation, academic performance, and STEM persistence intentions for students in transferable general education biological science courses offered at community colleges. This quantitative research study was conducted in two phases at one campus of a large, multi-campus community college in a major urban area in a Mid-Atlantic state. In the initial phase, the researcher administered the survey to students who volunteered to participate in the study. The students who participated were enrolled in a transferable general education biological science course at the study location during the final four weeks of the semester. In the first phase, a survey containing 34 statements from the MLQ 5X-short, the MSLQ, and demographic information was administered to 178 students enrolled in transferable general education biological science courses. In the second phase, data on the student’s final numerical course grade was collected from the instructor. A regression analysis was conducted to determine if such a relationship exists. The study did not find a statistical relationship between perceived transformational teacher leadership and academic success or intent to persist in STEM coursework. The study, however, did find a
Notas sobre la historia y el impacto de las leyes de servicios públicos de 1994 (Notes on the History and Impact of the Colombian Public Utility Laws From 1994)

Spanish Abstract: Este documento describe los antecedentes y la historia de la concepcion, discusion y aprobacion por parte del Congreso colombiano de las leyes de servicios publicos (leyes 142 y 143 de 1994). Existe un amplio consenso de que estas leyes crearon las condiciones institucionales y economicas para avanzar en la solucion de la aguda carencia de acceso a agua potable, electricidad, gas y telefonia en los hogares colombianos que existia antes de la decada de los anos noventa. De hecho, el notable aumento de la cobertura de los servicios publicos a lo largo de los ultimos veinticinco anos es un testimonio del beneficio de las reformas promulgadas en 1994. Es tambien un ejemplo de como, con pragmatismo, el pais pudo resolver un problema social serio dentro del marco de los procedimientos democraticos y una amplia deliberacion. English Abstract: This paper describes the background, conception, discussion, and approval by the Colombian Congress of the Public Service Laws (leyes 142 y 143 de 1994). There is a widespread consensus that these Laws created the institutional and economic conditions for solving the acute lack of access to drinkable water, electricity, gas, and telephone services in Colombian households in the 1980’s. In fact, the impressive increase in coverage in all public services throughout the last 25 years is a testament to the benefit of the reforms enacted in 1994. This is also an example of how, with pragmatism, the country was able to solve a serious social problem within the democratic procedures and open discussions.

Association of vascular endothelial growth factor A gene (VEGFA) polymorphisms, rs699947 and rs1570360, with diabetic retinopathy and altered VEGF secretion in Pakistani patients with Type 2 diabetes mellitus: A case-control study

Background: The incidence of type 2 diabetes mellitus (T2DM) is rising in working age adults in Pakistan. Diabetic patients have a greater chance for developing diabetic retinopathy (DR). There is negligible research on the genetic factors contributing to DR in Pakistani population. This study was done to investigate the association of vascular endothelial growth factor A gene (VEGFA) polymorphisms, 2578 C/A (rs699947) and 1154 G/A (rs1570360) with T2DM, diabetic retinopathy and serum VEGF levels in Pakistani patients. Methods: A case-control study, conducted from Jan 2017 to Dec 2018, including 450 subjects: 150 DR, 150 diabetics without retinopathy (DWR) and 150 healthy controls (HC). Genotyping was done by ARMS-PCR and serum VEGF levels were measured by ELISA. Descriptive and inferential statistics were calculated to compare genotypic / allelic frequencies and biochemical variables. Results: No statistically significant association of rs699947 and rs1570360 genotypic and allelic frequencies were found with DR as compared to DWR. The rs699947 heterozygosity was associated with DWR and homozygous mutant allele A with DWR and DR as compared to HC. Upon stratifying DR into non- proliferative (NPDR) and proliferative (PDR) sub- types, rs699947 AA genotype was significantly associated with PDR as compared to DWR in univariate and multinomial regression analysis. In allelic, dominant and recessive models, the minor allele A showed significant association with DWR and DR as compared to HC. Significantly raised serum VEGF levels were found in DR patients as compared to DWR and were associated with rs699947 and rs1570360 heterozygosity in DWR. Serum VEGF showed a positive correlation with fasting plasma glucose (FPG), cholesterol and LDL-C in DR and DWR groups. rs699947 genotype showed significant association with DWR and DR in Punjabi and Pathan and with DR in Kashmiri ethnic groups compared to HC. rs1570360 was significantly association with DR as compared to DWR in Kashmiri ethnic group. Conclusion: Our study endorses the role of VEGF 2578C/A (rs699947) gene polymorphism in the pathogenesis of T2DM and proliferative diabetic retinopathy in Pakistani patients. Serum VEGF levels have a positive correlation with T2DM and severity of DR.
Exploring linguistic malleability across the life span: Age-specific patterns in quotative use

Abstract This article explores the degree and kind of lability that occurs throughout the life span of the individual during ongoing rapid change in the quotative system. Two comparative analyses trace speakers' use of be like across a shorter and a longer time span. Trend data reveal that the robust change is arrested in the middle age brackets; speakers in their thirties seem to display ‘retrograde movement’ (Sankoff & Wagner 2006) away from the community-wide change. This finding could be interpreted as incipient age-grading. A small-scale panel sample collected forty-two years after the initial interview suggests that some older speakers participate in the trend, albeit at very low frequencies. This finding, while exploratory at the moment, might be interpreted as indicative of ‘life-span change’ (Sankoff 2005). A conception of the change in progress in the quotative system as monotonous would thus both under and overestimate the rate of change. (Change across the life span, age-grading, retrograde change, life-span change, quotation, style, language ideologies)*

Guided self-help group therapy for women with binge eating disorder

Background Self-help was found to be beneficial in terms of reduced binge eating, improved abnormal eating attitudes, and higher abstinence rates. They are typically brief and less costly compared with other therapies. Objectives The present study was designed to assess the outcome of guided self-help group therapy on female patients with binge eating disorder (BED). Patients and methods In the present experimental clinical trial, 27 female patients between 18 and 45 years of age diagnosed with BED were enrolled in guided self-help group therapy once weekly for 12 consecutive weeks. Prepsychometric and postpsychometric assessment was carried out to measure eating pathology, frequency of binge eating episodes, and self-esteem using Eating Disorder Examination, Symptom Checklist (SCL90-R), and Rosenberg’s self-Esteem Scale in addition to BMI. Results Patients showed a significant decrease in frequency of binge eating episodes (P=0.000), less over concern of body weight and shape, less BMI (P=0.000), and less psychological distress with no difference in self-esteem. Conclusion Guided self-help therapy is effective in reducing the severity of BED.

The GC content of the cp genome of M. ofeliae is 39.3%. The cp genome encoded a set of 113 genes, containing 79 protein-coding genes, 30 tRNA genes, and four rRNA genes. Phylogenetic analysis results that M. ofeliae is a sister to all other magnolias in the subfamily Magnolioideae.
Efficient removal of pharmaceuticals from water using graphene nanoplatelets as adsorbent

Recently, pharmaceutical pollutants in water have emerged as a global concern as they give threat to human health and the environment. In this study, graphene nanoplatelets (GNPs) were used to efficiently remove antibiotics sulfamethoxazole (SMX) and analgesic acetaminophen (ACM) as pharmaceutical pollutants from water by an adsorption process. GNPs; C750, C300, M15 and M5 were characterized by high-resolution transmission electron microscopy, Raman spectroscopy, X-ray diffraction and Brunauer–Emmett–Teller. The effects of several parameters viz. solution pH, adsorbent amount, initial concentration and contact time were studied. The parameters were optimized by a batch adsorption process and the maximum removal efficiency for both pharmaceuticals was 99%. The adsorption kinetics and isotherms models were employed, and the experimental data were best analysed with pseudo-second kinetic and Langmuir isotherm with maximum adsorption capacity (Qm) of 210.08 mg g−1 for SMX and 56.21 mg g−1 for ACM. A regeneration study was applied using different eluents; 5% ethanol-deionized water 0.005 M NaOH and HCl. GNP C300 was able to remove most of both pollutants from environmental water samples. Molecular docking was used to simulate the adsorption mechanism of GNP C300 towards SMX and ACM with a free binding energy of −7.54 kcal mol−1 and −5.29 kcal mol−1, respectively, which revealed adsorption occurred spontaneously.
Using adjoint-based optimization to enhance ignition in non-premixed jets

Gradient-based optimization is used to reliably and optimally induce ignition in three examples of laminar non-premixed mixture configurations. Using time-integrated heat release as a cost functional, the non-convex optimization problem identified optimal energy source locations that coincide with the stoichiometric local mixture fraction surface for short optimization horizons, while for longer horizons, the hydrodynamics plays an increasingly important role and a balance between flow and chemistry features determines non-trivial optimal ignition locations. Rather than identifying a single optimal ignition location, the results of this study show that there may be several equally good ignition locations in a given flow configuration.
A new approach to integrable evolution equations on the circle

We propose a new approach for the solution of initial value problems for integrable evolution equations in the periodic setting based on the unified transform. Using the nonlinear Schrödinger equation as a model example, we show that the solution of the initial value problem on the circle can be expressed in terms of the solution of a Riemann–Hilbert problem whose formulation involves quantities which are defined in terms of the initial data alone. Our approach provides an effective solution of the problem on the circle which is conceptually analogous to the solution of the problem on the line via the inverse scattering transform.
Characterization of the complete mitochondrial genome of Lysmata amboinensis (Hippolytidae, Decapoda) and its phylogenetic analysis

Abstract The complete mitochondrial genome of Lysmata amboinensis was obtained and described in this study. This complete mitochondrial genome is 16,735 bp in length and consists of 13 protein-coding genes (PCGs), 2 ribosomal RNA genes (rRNA), and 22 transfer RNA genes (tRNA). A total of 23 genes were encoded by the heavy strand. The overall base composition of the heavy-strand was 31.68% A, 14.31% G, 21.65% C, and 32.36% T, with a high A + T content of 64.05%. The phylogenetic analysis suggested that hippolytidae shrimp may be considered as the polyphyletic taxon. These results are useful for understanding the phylogenetic relationships and evolution of Hippolytidae shrimp.

Abstract Alstroemeria, a member of the Alstroemeriaceae family, is a species from South America. The chloroplast genome of Alstroemeria spp. was completed by de novo assembly using a small amount of whole genome sequencing data. The chloroplast genome of Alstroemeria spp. was 155,672 bp in length consisting of 84,379 bp of large single copy, 17,815 bp of small single copy, and 26,739 bp of a pair of inverted repeat regions. A total of 157 genes were annotated including 103 protein-coding genes (PCGs), 46 tRNA genes, and eight rRNA genes. Maximum likelihood phylogenetic analysis with seven species belonging to the Alstroemeriaceae or Liliaceae family revealed that Alstroemeria spp. is grouped with the species in the Alstroemeriaceae family.
Percutaneous left atrial appendage occlusion in nonvalvular atrial fibrillation patients with coronary heart disease

Purpose To evaluate the 12-month outcomes of the percutaneous left atrial appendage occlusion (LAAO) procedure in nonvalvular atrial fibrillation (NVAF) patients with coronary heart disease (CAD). Materials and Methods 51 NVAF patients were consecutively accepted LAAO between June 2015 and July 2017. Patients were devided in two groups: 15 with CAD and 36 without CAD. All patients were followed up at 1st, 3rd, 6th, and 12th month after discharge with transesophageal echocardiography (TEE) examination repeated at the same time. Results Among these 51 patients (average age 64.4±10.0, 33.3% female), the procedural success rate was 98% (50/51). During 12-month follow-up, there were no hemorrhagic stroke or major bleeding. The risk of thromboembolism based on CHA2DS2-VASc score (3.1±1.6 vs. 5.2±1.1, P<0.001) and the risk of hemorrhage based on HAS-BLED score (2.2±1.2 vs. 3.1±1.0, P=0.009) in CAD group were significantly higher. The incidence of end-point events had no statistical difference between CAD and non-CAD. Compared with CAD patients who accepted long-term antithrombotic medication, there was no obvious difference in stroke rate and mortality in CAD accepted LAAO group, whereas a further reduction of hemorrhage (n=5/20% vs. n=0, P=0.039) was shown. A significant correlation (P<0.001, r=0.580) was detected between moderate or severe left atrial spontaneous echo contrast (LASEC) and the composite end point events. Conclusion There are similar safety and effectiveness for LAAO procedure in NVAF patients with CAD and without CAD under new oral anticoagulants applied post-implantation anticoagulation strategy. Meanwhile, LASEC is a predictive factor of LAAO in NVAF patients combined CAD.

Conclusions: The quality of adjustment of the confirmatory analysis corroborates the validity of the adapted version in hospital care contexts.
Hearing sensitivity and amplitude coding in bats are differentially shaped by echolocation calls and social calls

Differences in auditory perception between species are influenced by phylogenetic origin and the perceptual challenges imposed by the natural environment, such as detecting prey- or predator-generated sounds and communication signals. Bats are well suited for comparative studies on auditory perception since they predominantly rely on echolocation to perceive the world, while their social calls and most environmental sounds have low frequencies. We tested if hearing sensitivity and stimulus level coding in bats differ between high and low-frequency ranges by measuring auditory brainstem responses (ABRs) of 86 bats belonging to 11 species. In most species, auditory sensitivity was equally good at both high- and low-frequency ranges, while amplitude was more finely coded for higher frequency ranges. Additionally, we conducted a phylogenetic comparative analysis by combining our ABR data with published data on 27 species. Species-specific peaks in hearing sensitivity correlated with peak frequencies of echolocation calls and pup isolation calls, suggesting that changes in hearing sensitivity evolved in response to frequency changes of echolocation and social calls. Overall, our study provides the most comprehensive comparative assessment of bat hearing capacities to date and highlights the evolutionary pressures acting on their sensory perception.
