Teacher Professional Learning: Learning to WALK and the NSW Quality Teaching Framework

This paper reports on a research case study, conducted in a school in Western Sydney, Australia, in which teachers worked with researchers and students to create learning experiences that reflected both intellectual quality and significance – two dimensions of the NSW Quality Teaching Framework (QTF). Findings suggest that these dimensions of the QTF were not implemented in a balanced way and this reflected a lack of support for the professional learning of teachers which the researchers could have helped to address, but did not. The paper argues that teachers should be supported by ongoing professional learning in order to sustain innovation and change.
Response of the Ross Ice Shelf, Antarctica, to ocean gravity-wave forcing

Abstract Comparison of the Ross Ice Shelf (RIS, Antarctica) response at near-front seismic station RIS2 with seismometer data collected on tabular iceberg B15A and with land-based seismic stations at Scott Base on Ross Island (SBA) and near Lake Vanda in the Dry Valleys (VNDA) allows identification of RIS-specific signals resulting from gravity-wave forcing that includes meteorologically driven wind waves and swell, infragravity (IG) waves and tsunami waves. The vibration response of the RIS varies with season and with the frequency and amplitude of the gravity-wave forcing. The response of the RIS to IG wave and swell impacts is much greater than that observed at SBA and VNDA. A spectral peak at near-ice-front seismic station RIS2 centered near 0.5 Hz, which persists during April when swell is damped by sea ice, may be a dominant resonance or eigenfrequency of the RIS. High-amplitude swell events excite relatively broadband signals that are likely fracture events (icequakes). Changes in coherence between the vertical and horizontal sensors in the 8–12 Hz band from February to April, combined with the appearance of a spectral peak near 10 Hz in April when sea ice damps swell, suggest that lower (higher) temperatures during austral winter (summer) months affect signal propagation characteristics and hence mechanical properties of the RIS.
Study of Knowledge of Students about Zika Virus Fever Infection , Tail University , Saudi Arabia

Zika virus is a member of the virus family Flaviviridae and the genus Flavivirus, transmitted by daytime-active Aedes mosquitoes, such as A. aegypti. This is a cross sectional study of knowledge of girls' students about zika virus infection in Taif University, Saudi Arabia. One hundred and thirty four (54.7%) of medical students and 111 (45.3%) of preparatory year students participated in the present study. The percent of knowledge was significantly higher among medical students as compared to Preparatory year students (47.0% versus 20.7%) (P= 0.000). About one quarter of students (24.9%) knew who is at risk of being infected. (29.1%) of medical students and (19.8%) of preparatory year students mentioned that anyone who lives in or travels to an area where Zika virus is found can get it from mosquito bites. About thirty-one percent mentioned to some extent how Zika infection is prevented. The percent was (37.3%) among medical students and (24.3%) among preparatory year students. The main mentioned points were mosquito control and not travelling to epidemic area. Because Zika virus outbreaks could cause additional burdens on all levels of the health care system, it is essential to improve and implement protocols and well established plans for the patient screening and treatment and increasing knowledge of medical workers.
Relationship between College Student Identity Development and Readiness for Change

This study examines the relationship between college students’ developmental level of identity formation and their choice to make intentional changes in behavior. Specifically, it examines whether there is a relationship between the level of identity development of college students according to Chickering’s model, measured by the Erwin Identity Scale (EIS), and the level of Readiness for Change concerning alcohol use following the Stages of Change Model by Prochaska and DiClemente. Correlational analyses in the form of multivariate regression is used to examine relationships between the various assessment measures. This helped answer the research questions: Is there a relationship between identity formation developmental levels and Readiness for Change, and do the subscales from the Stages of Change Readiness and Treatment Eagerness Scale (SOCRATES) relate individually to any of the subscales of the EIS? The results of the multiple regression analysis conducted with the Recognition subscale of the SOCRATES as the dependent variable and the three subscales of the EIS as the predictors indicated that two of the EIS subscales, Sexual Identity and Comfort about Body and Appearance had a significant relationship to Recognition. The EIS subscale of Confidence showed no significant relationship to Recognition. The possibilities of linking developmental level and issues around changing the drinking behavior of college students open up a way of evaluating college students’, which could alter the counselors’ approach to which interventions they would choose. Since the choice of intervention is imperative to the success of the counseling process, the college students’ level of identity formation may be related to Readiness for Change, and that by identifying students’ identity level and COLLEGE STUDENT IDENTITY DEVELOPMENT AND READINESS FOR CHANGE 5 matching the identity level with counseling approaches, counselors may be more effective in helping students make changes in potentially harmful drinking practices.

The Anti-angiogenic Activity of Matricaria Chamomilla Flowers Extraction

Background: The Matricariachamomilla is widely used in Asian countries as the traditional medicine to treat various diseases. Objective: The possible anti-angiogenic activity of Matricaria chamomilla flowers extractswas aimed to be investigated. Subjects and methods:The powder of the Matricariachamomilla flowers was extracted sequentially with petroleum ether, chloroform, methanol and water using the cold method "maceration" as extraction process. The ex vivo rat aorta ring assay was used to screen the extracts for possible anti–angiogenesis activity, this assay was also used to determine the dose–response effect of the active extract by preparing serial concentrations. Free radical scavenging activities of the extracts were determined using 1, 1–diphenyl–2– picrylhydrazyl) assay (DPPH). Results: The obtained data revealed that the four extracts exhibited significant inhibition of blood vessels growth when they were compared to the negative control (received DMSO 1%) (P<0.05) amidst them methanol extract was shown to have significant inhibition of blood vessels growth with comparable effect to positive control (acetylsalicylic acid ). Methanol extract of Matricariachamomillaflowers exhibited a significant dose–dependent anti–angiogenesis effect with IC50(29.85μg/ml). Furthermore, methanol extracts exhibited a significant free radical scavenging activity (P<0.05) with IC50 (81 μg) compared to other extracts. Conclusion: the results revealed that methanol extracts of Matricariachamomilla flowers exhibited the most significant anti– angiogenesis activityand this activity may be due to the high free radical scavenging capacity
Measuring Homicide by Police Officers

of agreement between the Uniform Crime Reports andc the Vital Statistics of the United States,2 and the monitoring function of coroners in recording homicide events all support the view that official statistics provide a highly accurate measure of homicide. The excellence of this official measurement, however, is confined to citizens killing other citizens. The official measurement of officials killing citizens falls far short of excellence. The widespread American belief that official killings do not constitute violence" is reflected by the complete absence of su h killings from the Uniform Crime Reports,4 most police departments' annual reports, and the limited summary treatment they receive in the Vital Statistics, where no figures are published below the state level.
Two-step Runge-Kutta methods and hyperbolic partial differential equations

The purpose of this study is the design of efficient methods for the solution of an ordinary differential system of equations arising from the semidiscretization of a hyperbolic partial differential equation. Jameson recently introduced the use of one-step Runge-Kutta methods for the numerical solution of the Euler equations. Improvements in efficiency up to 80% may be achieved by using two-step Runge-Kutta methods instead of the classical onestep methods. These two-step Runge-Kutta methods were first introduced by Byrne and Lambert in 1966. They are designed to have the same number of function evaluations as the equivalent one-step schemes, and thus they are potentially more efficient. By solving a nonlinear programming problem, which is specified by stability requirements, optimal two-step schemes are designed. The optimization technique is applicable for stability regions of any shape.
Phosphorus loss in agricultural drainage: historical perspective and current research

The importance of P originating from agricultural sources to the nonpoint source pollution of surface waters has been an environmental issue for decades because of the well-known role of P in eutrophication. Most previous research and nonpoint source control efforts have emphasized P losses by surface erosion and runoff because of the relative immobility of P in soils. Consequently, P leaching and losses of P via subsurface runoff have rarely heen considered important pathways for the movement of agricultural P to surface waters. However, there are situations where environmentally significant export of P in agricultural drainage has occurred (e.g., deep sandy soils, high organic matter soils, or soils with high soil P concentrations from long-term overfertilization andlor excessive use of organic wastes). In this paper we review research on P leaching and export in subsurface runoff and present overviews of ongoing research in the Atlantic Coastal Plain of the USA (Delaware), the midwestern USA (Indiana), and eastern Canada (Quehec). Our objectives are to illustrate the importance of agricultural drainage to nonpoint source pollution of surface waters and to emphasize the need for soil and water conservation practices that can minimize P losses in suhsurface runoff.
THERMAL PROPERTIES, STRUCTURE AND MORPHOLOGY OF GRAPHENE REINFORCED POLYETHYLENE TEREPHTHALATE/POLYPROPYLENE NANOCOMPOSITES (Sifat Termal, Struktur dan Morfologi Graphene Bertetulang Polietilena Tereftalat /Polipropilena)

In this work the thermal properties, structure and morphology of a blend of polyethylene terephthalate (PET) and polypropylene (PP) reinforced with graphene nanoplatelets (GNP) were investigated. A blend of PET/PP (70/30 weight percent) compatibilized with styrene-ethylene-butylene-styrene grafted maleic anhydride triblock copolymer (10 phr) were fabricated by melt extrusion process in a twin screw extruder. The effective thermal conductivity of the nanocomposites increased as a function of the GNP concentration. More than 80% increase in effective thermal conductivity was observed for the 7 phr reinforced sample compared to the neat blend. This observation was attributed to the development interconnected GNP sheets which formed heat conductive bridges that are suitable for maximum heat transfer. However, in the case of thermal stability which is a function of dispersibility of GNP in polymer matrix, the maximum increase was observed at 3 phr GNP loading which could be attributed to the uniform dispersion of GNPs in the matrix. It is explained that the GNP nanofillers migrated to the surface of matrix forming an effective oxygen barrier due to char formation. Morphological studies revealed uniform dispersion graphene in the polymer matrix at 3 phr GNP loading along with isolated instances of exfoliation of the graphene layers.
Properties of Extract from Okara by Its Subcritical Water Treatment

Okara was treated with subcritical water at temperatures ranging from 170 to 260°C for various times. After clarification, the extracts were analyzed for their protein and carbohydrate contents, DPPH radical scavenging activity, and antioxidative activity. The carbohydrate content significantly decreased with the increasing treatment temperature and time. The protein content, however, increased with the increasing treatment temperature and slightly decreased with a heating time longer than 10 min. The extract obtained from the subcritical water treatment at 240°C for 5 min, which would be used to evaluate the antioxidative activity, provided the relatively highest radical scavenging activity and the activity tended to decrease with the prolonging heating time and temperature. The extract also exhibited a suppressive activity to the autoxidation of linoleic acid with the increasing weight ratio of the extract to linoleic acid. The results clearly showed okara still contained highly valuable substances for human consumption.
Vector Autoregressions with Parsimoniously Time Varying Parameters and an Application to Monetary Policy

This paper studies vector autoregressive models with parsimoniously time-varying parameters. The parameters are assumed to follow parsimonious random walks, where parsimony stems from the assumption that increments to the parameters have a non-zero probability of being exactly equal to zero. We estimate the sparse and high-dimensional vector of changes to the parameters with the Lasso and the adaptive Lasso. The parsimonious random walk allows the parameters to be modelled non parametrically, so that our model can accommodate constant parameters, an unknown number of structural breaks, or parameters varying randomly. We characterize the finite sample properties of the Lasso by deriving upper bounds on the estimation and prediction errors that are valid with high probability, and provide asymptotic conditions under which these bounds tend to zero with probability tending to one. We also provide conditions under which the adaptive Lasso is able to achieve perfectmodel selection. We investigate by simulations the properties of the Lasso and the adaptive Lasso in settings where the parameters are stable, experience structural breaks, or follow a parsimonious random walk. We use our model to investigate the monetary policy response to inflation and business cycle fluctuations in the US by estimating a parsimoniously time varying parameter Taylor rule. We document substantial changes in the policy response of the Fed in the 1970s and 1980s, and since 2007, but also document the stability of this response in the rest of the sample.
Resource Allocation and Inefficiency in the Financial Sector

I analyze whether banks are efficient at allocating resources across intermediation activities. Competition between lenders means that resources are needed to draw borrowers into credit matches. At the same time, imperfect information between lenders and borrowers means that resources are also needed for screening. I show that the privately optimal allocation of resources is constrained inefficient. In particular, too many resources are spent on getting rather than vetting borrowers but, once properly vetted, not enough matches are retained. Uninformed lending is thus inefficiently high, informed lending is inefficiently low, and a tax on matching activities helps remedy the situation.
Does Gender and Age Affect Investor Performance and the Disposition Effect

The focus of the paper is on individual investor trading characteristics, the disposition effect bias and its links to performance. The analysis is based on the individual investor subsample of the complete transaction data of the Estonian stock market. The Cox proportional hazard model, along with PGR-PLR analysis, is used to measure the disposition effect and trading intensity. I show that different gender and age groups have different trading intensity and security holding periods, which realise in differences in the disposition effect bias and performance. Portfolios of older age groups and female investors perform better. Lower portfolio returns are connected with a higher level of trading intensity, shorter holding periods and a higher level of the disposition effect bias.
The Current Status of Faculty Development Internationally

Excerpt: One of the valuable and exciting changes that have occurred in higher education in the last few decades is the steady growth in faculty development programs internationally. From the first programs that were established in the mid-part of the 20th century, there are now several countries where essentially all colleges and universities have such programs.
Effect of Prior Performance Experience Before Audiences on a Dominant and Nondominant Motor Response.

The purpose of this study was to determine if children's prior performance experience was a mediating factor in their performance of a dominant or novel task in an audience or no audience situation. Eighty 9-year-old boys were divided into experienced (n = 40) and nonexperienced (n = 40) groups based on prior youth sport experience and the absence of any performance experience before a formal audience. Half of each group learned a rotary pursuit task until they could perform the task with at least 60% accuracy. The other half did not practice the task. Groups were again divided for task performance in an audience or no audience situation so that the following treatments were observed for both experienced and nonexperienced groups: dominant task, no audience; dominant task, evaluative audience; novel task, no audience; novel task, evaluative audience. Task performance for each subject was five 20-sec trials on the photoelectric rotary pursuit task. The mean score of each set of five was used for data analy.
PROSPECTS FOR THE DETECTION OF FAST RADIO BURSTS WITH THE MURCHISON WIDEFIELD ARRAY

Fast radio bursts (FRBs) are short timescale (≪1 s) astrophysical radio signals, presumed to be a signature of cataclysmic events of extragalactic origin. The discovery of six high-redshift events at ∼1400 MHz from the Parkes radio telescope suggests that FRBs may occur at a high rate across the sky. The Murchison Widefield Array (MWA) operates at low radio frequencies (80–300 MHz) and is expected to detect FRBs due to its large collecting area (∼2500 m2) and wide field-of-view (FOV, ∼ 1000 deg2 at ν = 200 MHz). We compute the expected number of FRB detections for the MWA assuming a source population consistent with the reported detections. Our formalism properly accounts for the frequency-dependence of the antenna primary beam, the MWA system temperature, and unknown spectral index of the source population, for three modes of FRB detection: coherent; incoherent; and fast imaging. We find that the MWA's sensitivity and large FOV combine to provide the expectation of multiple detectable events per week in all modes, potentially making it an excellent high time resolution science instrument. Deviations of the expected number of detections from actual results will provide a strong constraint on the assumptions made for the underlying source population and intervening plasma distribution.
Serodiagnosis of Hepatitis B Virus Infection among Jessu Community of Gombe State, Nigeria

Hepatitis B virus causes disease of the liver and is a global health problem that leads to liver cirrhosis and hepatocellular carcinoma. Despite the dangers posed by this silent and deadly disease, there is little or no documented work on Hepatitis B infections in Jessu community, Gombe State, North East Nigeria. This study was undertaken to determine the sero-prevalence of Hepatitis B Virus infection and possible risk factors associated with the transmission of HBV. Blood samples (3ml) were collected from 196 eligible consented subjects and the serum samples were tested for the presence of HBsAg using On Site HBsAg Rapid Test Kit manufactured by CTK Biotech, USA. The OnSite HBV 5-Parameter Rapid Test also manufactured by CTK Biotech, USA was used to confirm those that were positive. Of the 196 eligible subjects examined, 5.6% were confirmed positive for HBsAg, 8.6% were males and 2.9% were females. Age distribution of HBsAg among the population shows the highest seroprevalence of 8.9% HBsAg in ages 16-30 years, followed by 4.5% in ages 31-45 years while ages 0-15 years had 3.5% seroprevalence. Participants who share sharp objects recorded the highest prevalence of 6.3% HCV infection followed by blood transfusion with 5.9% prevalence and those with multiple sex partners had the least prevalence of 1.8% HCV infection. The seroprevalence of 5.6% HBV in this study indicated the presence of HBV in Jessu Community in Gombe State, North East Nigeria.
Silicon photonic crystal nanostructures for refractive index sensing

The authors present the fabrication and optical investigation of silicon on insulator photonic crystal drop filters for use as refractive index sensors. Two types of defect nanocavities (L3 and H1−r) are embedded between two W1 photonic crystal waveguides to evanescently route light at the cavity mode frequency between input and output waveguides. Optical characterization of the structures in air and various liquids demonstrates detectivities in excess of Δn/n=0.018 and Δn/n=0.006 for the H1−r and L3 cavities, respectively. The measured cavity frequencies and detector refractive index responsivities are in good agreement with simulations, demonstrating that the method provides a background free transducer signal with frequency selective addressing of a specific area of the sensor chip.
Effects of Counteranions and Dissolved Oxygen on Chemical ZnO Deposition from Aqueous Solutions

In the chemical ZnO deposition on Pd-catalyzed glass from aqueous dimethylamineborane (DMAB) solutions, effects of counteranions (NO - 3 , Cl - , ClO - 4 , and SO 2- 4 ) and dissolved oxygen (DO) on the hydrolysis behavior of Zn 2+ and the growth regime of ZnO were studied using sodium and zinc salt solutions bubbled with O 2 , air, or Ar gas. The interaction of the counteranions with H + and Pd as well as Zn 2+ was suggested as an important factor for the chemical ZnO deposition, and it was found that only NO - 3 can raise the pH of a DMAB solution without DO, affording the continuous ZnO growth. Dissolved oxygen accelerated the ZnO nucleation process on the Pd and had less influence comparable to NO - 3 on the subsequent growth on the ZnO surface. The ZnO films deposited from Zn(NO 3 ) 2 -DMAB solutions bubbled with O 2 , air, or Ar gas were characterized with an X-ray diffractometer, field emission scanning electron microscope, UV-visible spectrophotometer, and Hall coefficient analyzer. The Ar-bubbled solution gave superior ZnO films in terms of crystallinity, growth orientation, surface morphology, and electrical conductivity due to the relatively moderate crystal nucleation compared to in the presence of DO.
