INFLUENCE OF TEACHERS' AGE, MARITAL STATUS AND GENDER ON STUDENTS' ACCADEMIC ACHIEVEMENT

The paper influence of teachers‟ age, marital status and gender on the academic achievement of secondary school students in English Language as a subject was the focus of the study. The population for the study was the 304 public senior secondary schools in the three senatorial districts of Edo State, Nigeria. The proportionate sampling technique was well to select 52 senior secondary schools. 52 senior secondary final year (SS III) English language teachers and their 1,689 students consisted the sample for the study. Instruments used for the study are the English Language Teachers‟ Age, Marital Status and Gender Questionnaire (ELTAMGQ) and the English Language Achievement Test (ELAT). Data was collected and analyzed using the one-way ANOVA and t-test. Alfa level set at 0.05 level of significance. The findings of the study revealed that students‟ academic achievement is significantly influenced by teachers‟ age, marital status whereas, teachers‟ gender did not have a significant influence on students‟ academic achievement.
Magnetite from magnetotactic bacteria; size distributions and twinning

We studied intracellular magnetite particles produced by several morphological types of magnetotactic bacteria including the spirillar (helical) freshwater species, Magnetospirillum magnetotacticum, and four incompletely characterized marine strains: MV-1, a curved rod-shaped bacterium; MC-1 and MC-2, two coccoid (spherical) microorganisms; and MV-4, a spirillum. Particle morphologies, size distributions, and structural features were examined using conventional and high-resolution transmission electron microscopy. The various strains produce crystals with characteristic shapes. All habits can be derived from various combinations of the isometric {111}, {110}, and {100} forms. We compared the size and shape distributions of crystals from magnetotactic bacteria with those of synthetic magnetite grains of similar size and found the biogenic and synthetic distributions to be statistically distinguishable. In particular, the size distributions of the bacterial magnetite crystals are narrower and have a distribution asymmetry that is the opposite of the nonbiogenic sample. The only deviation from ideal structure in the bacterial magnetite seems to be the occurrence of spinel-law twins. Sparse multiple twins were also observed. Because the synthetic magnetite crystals contain twins similar to those in bacteria, in the absence of characteristic chains of crystals, only the size and shape distributions seem to be useful for distinguishing bacterial from nonbiogenic magnetite.
NATURAL HISTORY AND DISTRIBUTION OF SELVA CACIQUES (CACICUS KOEPCKEAE) IN THE PERUVIAN AMAZON

We present new data on the distribution, habitats, social behavior, and nesting of the Selva Cacique (Cacicus koepckeae), obtained during six years of surveys at 37 sites in the departamentos Ucayali and Cusco, Amazonian Peru. Our 10 new localities for this cacique were close to smaller rivers, at altitudes of 340-660 m a.s. l. , and had patches of Guadua sarcocarpa bamboo. Sonograms and descriptions of the song (previously unknown) and other vocalizations are presented. We found two active nests, elongated pendant bags hanging over streams, mostly built with blackish rhizomorphs of the fungus Marasmius. We observed from three to four individuals at each nest, sharing some parental duties like nest guarding and attacks to potential predators, an unusual behavior for solitary breeding caciques. The nests of Selva, Golden-winged (C. crhysopterus), and Ecuadorian (C. sclateri) caciques are similar, all suspended over water. This similarity supports the view of traditional taxonomy in suggest- ing a close phylogenetic relationship between the three species. Accepted 4 September 2012.
South Korean Teachers' Perceptions of Integrating Information and Communication Technologies into Literacy Instruction

We investigated South Korean literacy and language arts teachers’ perceptions about integrating interactive communication technologies (ICTs) into instruction. The survey addressed their access to various applications and technologies associated with ICTs, access to technological support, frequency and importance of use, and obstacles to and conceptions of integrating ICTs. Descriptive and correlational data are reported suggesting that although classroom use of ICTs is mandated at the national level, South Korean teachers perceive access to some tools and applications, as well as the availability of technical assistance at both the school and district level, to be limited. We compare data from this study to our findings from a similar study conducted in the USA and discuss what the findings reveal about integration of ICTs into literacy instruction in South Korea. The implications for education policy in South Korea and for continued research to clarify findings across national and cultural boundaries are discussed. For example, despite reporting greater impact of obstacles and less technical support than their US counterparts, South Korean teachers reported using ICTs more frequently than teachers from the USA.
Results of X-shooter data reduction software on laboratory frames

We present the current state of the Data Reduction Software (DRS) being developed at APC, Paris Observatory, Amsterdam University and ESO for the X-shooter echelle spectrograph. X-shooter is the first VLT second generation instrument, which will have its first light during the fall of the current year and will be available to the astronomical community starting April 2009. The DRS will be fully integrated in the ESO VLT data flow environment and it will use the ESO Common Pipeline Library. X-shooter data have two main characteristics, on the one hand the exceptionally wide band (0.3 - 2.4 micron) covered in a single exposure, and on the other hand the spectral format with highly curved orders and tilted lines. After a brief description of the reduction process, the main results obtained up to now on simulated and laboratory data are reported. In particular the precision of wavelength calibration and sky subtraction are discussed.
Distributed Computing Framework Based on Software Containers for Heterogeneous Embedded Devices

The Internet of Things (IoT) is represented by millions of everyday objects enhanced with sensing and actuation capabilities that are connected to the Internet. Traditional approaches for IoT applications involve sending data to cloud servers for processing and storage, and then relaying commands back to devices. However, this approach is no longer feasible due to the rapid growth of IoT in the network: the vast amount of devices causes congestion; latency and security requirements demand that data is processed close to the devices that produce and consume it; and the processing and storage resources of devices remain underutilized. Fog Computing has emerged as a new paradigm where multiple end-devices form a shared pool of resources where distributed applications are deployed, taking advantage of local capabilities. These devices are highly heterogeneous, with varying hardware and software platforms. They are also resource-constrained, with limited availability of processing and storage resources. Realizing the Fog requires a software framework that simplifies the deployment of distributed applications, while at the same time overcoming these constraints. In Cloud-based deployments, software containers provide a lightweight solution to simplify the deployment of distributed applications. However, Cloud hardware is mostly homogeneous and abundant in resources. This work establishes the feasibility of using Docker Swarm – an existing container-based software framework – for the deployment of distributed applications on IoT devices. This is realized with the use of custom tools to enable minimal-size applications compatible with heterogeneous devices; automatic configuration and formation of device Fog; remote management and provisioning of devices. The proposed framework has significant advantages over the state of the art, namely, it supports Fog-based distributed applications, it overcomes device heterogeneity and it simplifies device initialization.
Investigation of New Methods for Numerical Stochastic Perturbation Theory in $\varphi^4$ Theory

Numerical stochastic perturbation theory is a powerful tool for estimating high-order perturbative expansions in lattice field theory. The standard algorithms based on the Langevin equation, however, suffer from several limitations which in practice restrict the potential of this technique. In this work we investigate some alternative methods which could in principle improve on the standard approach. In particular, we present a study of the recently proposed Instantaneous Stochastic Perturbation Theory, as well as a formulation of numerical stochastic perturbation theory based on Generalized Hybrid Molecular Dynamics algorithms. The viability of these methods is investigated in $\varphi^4$ theory.
RIBLET DRAG REDUCTION AND THE EFFECT OF BULK FLUID ROTATION IN A FULLY TURBULENT TAYLOR-COUETTE FLOW

Low drag surfaces are often desired in many industries with applications in open and closed channel flows, such as ship hulls and pipe flows. Drag reduction is a phenomenon that can have substantial energy savings, resulting in ecological and economical benefits. We use a Taylor-Couette facility as experimental instrument to measure the drag change of turbulent wall-bounded flows above modified surfaces [2, 4]. In this manuscript, we apply a riblet surface to observe the drag change compared to a smooth reference surface. Riblets are small surface protrusions which are aligned in the flow direction. They reduce drag by disturbing the spanwise motion of the flow at the surface and thereby moving turbulent vortices further away from the wall [1]. The turbulent flow is investigated via tomo-PIV measurements, which identify the change in flow structures and velocity profile of the flow between two counter-rotating cylinders.
Numerical Simulation of Performance Augmentation in a Plate Fin Heat Exchanger Using Winglet Type Vortex Generators

A detailed evaluation of the performance parameters in the laminar flow regime with regard to the enhancement of heat transfer using winglet type vortex generators has been accomplished in this study. Three dimensional numerical studies of flow structure and laminar convectionheat transfer are performed in a plate fin heat exchanger with longitudinal vortex generators (LVGs) in present paper. The Effects of common flow up and common flow down pairs of vortices produced by LVGs with two different shapes of the winglets, a pair of rectangular winglet (RWP) and a pair of delta winglet (DWP), are studied at various Reynolds numbers. The results show that effect of LVGs could effectively enhance the heat transfer of the heat exchanger. According to the non-dimensional defined parameter for evaluation of performance, (Num/Num,0)/(f/f0), the channel with DWP shows better overall performance than RWP. The common flow down configuration of DWP shows a better overall performance at Reynolds numbers lower than 720 and common flow up configuration of DWP shows a better overall performance at Reynolds numbers more than 720; also, the common flow down configuration shows a better overall performance than the common flow up configuration for RWP.
Neural signatures underlying individual differences in source monitoring abilities

In the present study, source-monitoring processes that are required to distinguish a memory trace of a true event from an internally generated false memory were investigated, using the Deese-Roediger-McDermott paradigm (DRM) to induce false memories, while obtaining fMRI measurements. In order to explore individual differences in memory performance and source monitoring abilities, participants were divided into Low False Memory (LFM) and High False Memory (HFM) groups based on accuracy for critical lure words. Subsequent analyses of the two groups’ behavioural data revealed intrinsic differences in accuracy and response time patterns, while post hoc ROI analyses of the groups’ functional data, consistent with the behavioural findings, revealed significant enhanced activations during recognition for the LFM group compared to the HFM group in areas previously shown to be linked to memory and source monitoring performance. As far as we know, this is the first study to identify possible neural mechanisms underlying individual differences in source monitoring abilities related to false memory susceptibility.
Becoming Economically Independent: weakening or Strengthening Parental Ties?

This paper analyses patterns of behaviours of about three thousand graduates in some northern and central Italian univ ersities. Different approaches to the job market and/or to further qual ifications are followed up during the year after graduation and are related both to some choices adopted previously at university and to family trai ts, by means of longitudinal methods of Event History Analysis (EHA). Apparent behavioural inertia from college to the postgraduat e period reveals a commonly shared underlying attitude. Also, family i nfluence seems well conveyed by parents’ educational levels, which emph asize the mothers’ role in improving graduates qualifications and the fathe rs’ function in involving their children in self employment.
Examining the Spatial Ability Phenomenon from the Student's Perspective

This phenomenological investigation examined the lived experience of technically-oriented students over the course of a single semester, attempting to answer the question, “What was it like for a student to experience the spatial ability phenomenon? ” The study included 12 interviewees and 8 focus group freshman participants at a Midwestern university. Data sources included interview transcripts, think aloud transcripts, task solutions, focus group transcripts, researcher journal entries, course performance data, course observation data, and spatial ability test data. This paper provides the holistic, structural description of the spatial phenomenon that emerged from the descriptions of the participants’ experience, as well as an expository on four of the five invariant themes that were elicited from the data. the collaborative session. Recommendations were made for future course improvements when a real world project is used in the curriculum. This paper also discusses changes in design process and the role of designers based on the collaborative session feedback.

SIMULATION OF IMPACTS OF DIFFERENT ANIMAL MANAGEMENT PRACTICES AND GEOGRAPHIC AREA ON LONG-TERM AIR QUALITY

Simulated impacts of different animal management practices and geographic areas on long-term air quality have been studied using our proposed BTA-AQP (building thermal analysis-air quality predictive) model and statistical analysis methods with four scenarios: building heat loss factor (BHLF), barn setpoint temperature (SPT), animal production schedule (APS), and geographic area (GA). The purpose was to help animal producers and environmental researchers understand the parameters influencing air quality and find a simple, inexpensive, and effective abatement strategy to alleviate airborne pollution from livestock production facilities instead of numerous high-cost gas/odor control technologies. The predicted results indicated that the BHLF scenario had a negligible effect on the source air quality, and the SPT scenario was capable of reducing indoor gas levels during hot weather conditions while the corresponding gas emissions did not increase substantially. Thus, current barn setpoint temperature strategies provide one method to decrease the risk of relatively high gas concentrations (especially H2S concentration) inside the building and protect the health of workers and animals. The APS scenario had no significant effect on mean annual gas concentrations but could lead to a moderate decrease in mean annual gas emissions. It was also found that the GA factor, for the swine deep-pit barns with similar building characteristics and management practices, might have a large impact on indoor gas concentrations but very little effect on mean annual gas emissions.
Exports , Productivity and In ovation : Evidence from Portugal using micro data

This study examines the evolution of Portuguese exports to Spain and its determinants in the period 2004-2008, based on a sample of the 97 largest exporters to Spain. The econometric study, using panel data and a static and dynamic analysis, considers as theoretically relevant explanatory variables productivity, equity capital, remuneration and innovation measured by the expenditure on research and development (R&D). The static results of the estimated models confirm the positive influence of productivity and equity capital on the variation of exports, and the negative effect of the labour costs. The variable R&D is statistically significant, with a positive effect on Portuguese exports in the dynamic model. The dynamic estimations also suggest that the exports in the previous period have a positive effect on contemporaneous exports.
Cierre cognitivo, sexismo y religiosidad: diferencias y similitudes entre grupos de adolescentes con distinta cultura

Desde el ambito de la cognicion social motivada, la necesidad de cierre cognitivo emerge como una variable crucial para la mejor comprension de las diferencias individuales en variables psicosociales asociadas a la cultura y, ademas, susceptible de tener en cuenta en programas de intervencion cuyo objetivo vaya dirigido a modificar actitudes ancladas en el prejuicio y la discriminacion. En la presente investigacion se ha realizado un estudio de este constructo motivacional y su relacion con el sexismo y la religiosidad en una muestra de adolescentes cristianos y musulmanes, todos ellos residentes en un contexto social con un marcado caracter multicultural. De acuerdo con los datos obtenidos, no se han encontrado diferencias segun la religion en necesidad de cierre cognitivo y sexismo. Sin embargo, se han encontrado diferencias por sexo en necesidad de cierre cognitivo y sexismo hostil. La necesidad de cierre cognitivo correlaciono de una forma estadisticamente significativa con el sexismo (hostil y benevolente), y es un buen predictor del mismo. Los musulmanes puntuaron de una forma significativamente mas elevada en los indicadores de religiosidad. Se discuten los resultados en el marco de la teoria del sexismo ambivalente y de investigaciones previas sobre psicologia de la religion.
Zum Alter des Plaggeneschs

Abstract. Der Plaggenesch entstand durch jahrhundertelange Dungung mit Plaggendung, der hauptsachlich aus Plaggen, d. h. flach abgehackten Heide- oder Grasstucken, und Stalldung bestand. Dadurch wurde der Ap-Horizont uber dem ursprunglichen Bodentyp immer machtiger bis zu 80 cm und mehr, und damit entstand der anthropogene Bodentyp „Plaggenesch". Entstehung, Aufbau, Eigenschaften und Verbreitung des Plaggeneschs werden beschrieben. Es wird geschildert, wie man das Alter, den Beginn der Plaggendungung feststellen kann. Hinweise geben Ortsnamen, die Geschichte der Ackerkultur sowie Scherben und andere Funde. Eine direkte Altersbestimmung erlaubt die 14C-Methode, indessen ist sie mit Fehlern behaftet, da die organische Masse der Plaggenesche nicht einheitlich ist, d. h. ein verschiedenes Alter haben kann. Es wird daher nur ein Mittelwert erzielt. Unter Beachtung aller Fehlerquellen wird auf Grund der bisher gewonnenen 14C-Werte das Alter der Plaggenesche, d. h. der Beginn der Plaggendungung, mit etwa 800—1200 Jahren angenommen. Dieses Alter stimmt mit den vorher auf anderem Weg gewonnenen Altersdatierungen einigermasen uberein.
Exports and Firm Productivity in Turkish Manufacturing: An Olley-Pakes Estimation

In this study, we examine the effects of exporting on the industry productivity following a two-step procedure using 4-digits industry level data of Turkish manufacturing sectors for the period 2003-2008. First, robust total factor productivity variable is obtained from a Cobb-Douglas production function following the semiparametric method of Olley and Pakes (1996), since productivity estimation by approximating the weighted sum of the inputs by OLS may suffer from simultaneity and selection biases. In the second stage of empirical analysis, the relationship between productivity and being net-exporter is estimated by fixed-effects panel data method. Results show that, productivity level for net-exporters is lesser than the level for net-importers indicating that industries are more prone to import and more competitive on import markets. We also show that when simultaneity and selection biases are not controlled for, the coefficient for the labor input is biased upward and the coefficient for the capital stock is biased downward
Solid-State FTIR Spectroscopic Study of Two Binary Mixtures: Cefepime-Metronidazole and Cefoperazone-Sulbactam

The structural information of the pharmaceuticals and insights on the modes of molecular interactions are very important aspects in drug development. In this work, two cephalosporins and antimicrobial combinations, cefepime-metronidazole and cefoperazone-sulbactam, were studied in the solid state using FTIR spectroscopy for the first time. Quantitation of the studied drugs and their binary mixtures was performed by integrating the peak areas of the characteristic well-resolved bands: υ (C=O) band at 1773 cm−1 for cefepime and ring torsion band at 826 cm−1 for metronidazole and υ (C=O) band at 1715 cm−1 for cefoperazone and ring torsion band at 1124 cm−1 for sulbactam. The results of this work were compared with the relevant spectrophotometric reported methods. This study provides data that can be used for the preparative process monitoring of the studied drugs in various dosage forms.
Parisian ruin with exponential claims

In this paper, we extend the concept of ruin in risk theory to the Parisian type of ruin. For this to occur, the surplus process must fall below zero and stay negative for a continuous time interval of specified length. Working with a classical surplus process with exponential jump size, we obtain the Laplace transform of the time of ruin and the probability of ruin in the infinite horizon. We also consider a diffusion approximation and use it to obtain similar results for the Brownian motion with drift.
