Examining the impact of L2 proficiency and keyboarding skills on scores on TOEFL-iBT writing tasks

A major concern with computer-based (CB) tests of second-language (L2) writing is that performance on such tests may be influenced by test-taker keyboarding skills. Poor keyboarding skills may force test-takers to focus their attention and cognitive resources on motor activities (i.e., keyboarding) and, consequently, other processes and aspects of writing (e.g., planning, revising) might be left unattended to, which can lead to poor text quality and lower test scores. Such effects might be more pronounced for L2 test-takers. This study investigated the impact of keyboarding skills on test-takers’ scores in the context of the TOEFL-iBT Writing Section. Each of 97 test-takers, with different levels of English language proficiency (low vs. high) and keyboarding skills (low vs. high), responded to two TOEFL-iBT writing tasks (independent and integrated) on the computer. Test scores were statistically compared across tasks and test-taker groups. The findings indicated that overall English language proficiency and writing ability in English contributed substantially to variance in task scores, while keyboarding skill had a significant, but weak, effect on task scores. Additionally, keyboarding skills effects depended on task type. While these findings support the claim that performance on TOEFL-iBT writing tasks depends mainly on test-taker English language proficiency, they also raise important questions about the relationships between keyboarding skills, L2 writing ability, and performance on CB L2 writing tests, as well as factors affecting these relationships.

Effects of polyvinylpyrrolidone on carbothermal reduction and nitridation of titanium nitride powder

AbstractTitanium nitride powders were synthesised via carbothermal reduction and nitridation of TiO2 non-hydrolytic gels using polyvinylpyrrolidone as the carbon source. Compared with solid carbon black as carbon resource, polyvinylpyrrolidone was dissolved in a mixture of absolute alcohol, titanium tetrachloride and dimethylformamide and can fully contact with the titanium source in the liquid–liquid mixture, which will contribute to increase the reaction and conversion rates of titanium nitride. The optimum parameters for polyvinylpyrrolidone molecular weight and C/Ti molar ratio were 1 300 000 and 12:1, respectively. The average grain size of Titanium nitride powders was 100 nm.

Gateway-Assisted Retransmission for Lightweight and Reliable IoT Communications

Message Queuing Telemetry Transport for Sensor Networks (MQTT-SN) and Constrained Application Protocol (CoAP) are two protocols supporting publish/subscribe models for IoT devices to publish messages to interested subscribers. Retransmission mechanisms are introduced to compensate for the lack of data reliability. If the device does not receive the acknowledgement (ACK) before retransmission timeout (RTO) expires, the device will retransmit data. Setting an appropriate RTO is important because the delay may be large or retransmission may be too frequent when the RTO is inappropriate. We propose a Gateway-assisted CoAP (GaCoAP) to dynamically compute RTO for devices. Simulation models are proposed to investigate the performance of GaCoAP compared with four other methods. The experiment results show that GaCoAP is more suitable for IoT devices.

Probable Importation of Dengue Virus Type 4 to Angola from Brazil

Probable Importation of Dengue Virus Type 4 to Angola from BrazilTo the Editor: The prevalence of dengue virus (DENV) infection in Africa may have been grossly underestimated for many years (1).Even though published reports are scarce, dengue has been documented in at least 34 countries in Africa (2).The role of travelers as sentinels of infectious disease has proven to be invaluable in this regard; dengue in returning travelers was the only evidence for local DENV transmission for 12 of these countries.During April 2013, simultaneous reports of travelers returning from Luanda, Angola, with dengue fever emerged from Israel, several countries in Europe, Canada, and South Africa; PCR and sequencing of viral RNA confirmed the causative species to be DENV type 1 (DENV-1) (3).Concomitantly, a large outbreak of dengue was confirmed by local authorities in Luanda, and DENV-1 was isolated in samples from local residents (4).The origin of the outbreak strain was not ascertained, but phylogenetic analysis suggested that it had close affinity with isolates from West Africa (4,5).These reports involved almost 100 travelers and >500 residents of Luanda who become within a short time.Active DENV transmission and occurrence of new cases in Luanda were still ongoing during early July 2013 (6), but since then, to our knowledge, no additional local data on DENV activity in Luanda have been published.We report 3 new cases of dengue fever acquired in Luanda during December 2013-February 2014.Two cases occurred in travelers who returned to Israel, and 1 occurred in a traveler who returned to Germany.All 3 cases occurred in middle-aged businessmen who had traveled to

Far‐field effects of Late Miocene subduction in the Eastern Carpathians: E‐W compression and inversion of structures in the Alpine‐Carpathian‐Pannonian region

Kinematic and paleostress data constrain a Late Miocene E‐W compressional event that affected the entire Alpine‐Carpathian‐Pannonian system after 9 Ma and prior to 5.3 Ma. The maximum horizontal compression directions obtained from 110 stations show a mean σ 1 orientation of 083°. Deformation is mainly strike‐slip. E‐W directed compression followed Early to Middle Miocene upper plate extension in the Pannonian Basin which was caused by the retreating subduction boundary in the outer Carpathians. This compressional event terminated Early to Middle Miocene eastward lateral extrusion of the Eastern Alps and reverted strike‐slip faults which bounded earlier extruded wedges such as the Salzachtal‐Ennstal fault, the Periadriatic fault, the Mur‐Mürz‐Vienna Basin fault system, and strike‐slip faults in the Western Carpathians. E‐W compression caused the reorientation of the extension direction of the Alpine crustal stack. East‐directed tectonic unroofing of the metamorphic domes in the central Eastern Alps terminated between 9 and 6 Ma and Early to Middle Miocene orogen‐parallel E‐W extension switched to Late Miocene N‐S extension which parallels modern topographic slopes. In the Pannonian Basin the change from synrift extension to Late Miocene compression during the postrift phase caused the pronounced postrift subsidence by stress induced downward flexure of the loaded lithosphere. We relate Late Miocene E‐W compression to coeval late‐stage west‐ directed subduction of the European plate below the Eastern Carpathians. Slab pull of the subducted plate caused subduction roll back and upper plate extension of the Pannonian area up to the Middle Miocene. Subduction slowed down and ceased when up to 60‐km‐thick buoyant continental crust entered the subduction zone. During the short period of continued convergence E‐W ‐directed compressive stress was transmitted across the subduction boundary into the upper plate. Compressive stress was transferred through the uppermost brittle crust of the earlier extended Pannonian region into the Eastern Alps, up to 1400 km behind the subduction zone. E‐W compression terminated during the Pliocene when the Pliocene to recent NNW‐SSE compressive stress field was established in Central Europe.

Effect of Some Physical Mutagens on Pseudomonas aeruginosa H3 in Alginate Production

Effect of physical mutagens on the ability of Pseudomonas aeruginosa H3 in alginate production was performed by subjection of the cell suspension of P. aeruginosa H3 to different doses of UV radiation (2, 4, 6, 8 and 10 J/m2) and LASER for (30, 60, 90 and 120 sec.), then cell suspension was spread on LB agar plates and incubated at 37 ˚C for 24hrs. After that, random selection of thirty colonies that arose from the cells subjection to the effect of different doses of UV radiation and laser were made (90% of the suspended cells were killed and were tested for their alginate production). Results showed that the mutagenesis by UV radiation caused an increase in the ability of P. aeruginosa H3 in alginate production. Over-producer mutant, H3R1, was obtained from this treatment. The productivity of the alginate from this mutant was 170mg/l in comparison with the productivity of wild type (70mg/l). On the other hand, results also showed that mutagenesis using LASER radiation caused an increase in the ability of P. aeruginosa H3 in alginate production. Over-producer mutant, H3R42, was obtained from this treatment characterized by its high ability in alginate production (130mg/l) in comparison with the productivity of wild type (70mg/l). Results of Fourier Transform-Infra Red (FT-IR) for alginate produced by the wild type of P. aeruginosa H3 and over-producer mutants H3R1 and H3R42 at a wide range of wave lengths absorbance (400-4000) cm-1 showed that there were no any structural differences in the chemical structure of alginate produced by them on the basis of infra-red light absorption by different functional groups of alginate

Incident Energy Dependence of Hadronic Activity

Two features of high-energy hadronic cascades have been long known to shielding specialists: (a) in a high-energy hadronic cascade in a given material (incident E {approx_equal} 10 GeV), the relative abundance and spectrum of each hadronic species responsible for most of the energy deposition is independent of the energy or species of the incident hadron, and (b) because {pi}{sup 0} production bleeds off more and more energy into the electromagnetic sector as the energy of the incident hadron increases, the level of this low-energy activity rises less rapidly than the incident energy, and in fact rises very nearly as a power of the incident energy. Both features are of great importance in hadron calorimetry, where it is the ``universal spectrum`` which makes possible the definition of an intrinsic e/h, and the increasing fraction of the energy going into {pi}{sup 0}`s which leads to the energy dependence of e/{pi}. We present evidence for the ``universal spectrum,`` and use an induction argument and simulation results to demonstrate that the low-energy activity scales as E{sup m}, with 0.80 {le} m {le} 0.85.

Transfer Learning for Volatility Pattern Prediction Across Global Stock Markets Using Lightweight Statistical Models

Abstract This study looks at using simple statistical models to predict changes in global stock markets. The goal is to create a system that can adjust to different market conditions without needing complex deep learning methods. Traditional methods often struggle because of different data types, regional financial differences, and limited data from international markets. To solve these problems, the study uses models like ARIMA and Exponential Smoothing. These models are combined with transfer learning techniques to match data features and patterns between different markets. Tests with data from the NYSE, BSE, and FTSE showed that these models predict well and use less computing power. This shows that statistical transfer learning can be an effective and easy-to-understand way to predict market changes. The new approach uses simple models instead of deep neural networks, which makes it more transparent and efficient. This system can help create strong, low-cost financial forecasting tools, especially useful in places with limited data or resources.

Investigating the expression of N-acetylglucosamine 6-0 sulfotransferases in myeloid cells and its implications on CD44 sulfation

The sulfation of proteoglycans and glycoproteins has been implicated in many biological processes. Glycoproteins on high-walled endothelial venules present sialyl 6-sulfo Lewis x determinants that can mediate lymphocyte homing to lymph nodes by serving as ligands for L-selectin on circulating lymphocytes. CD44 represents a family of glycoproteins that is expressed on most cell types. Interactions between CD44 and hyaluronic acid (HA) have been implicated in many facets of the inflammatory response, including leukocyte recruitment. CD44-HA binding is tightly regulated by several mechanisms including changes in CD44 glycosylation. Recently, increased sulfation of CD44 was correlated with increased HA binding induced by the pro-inflammatory cytokine, tumour necrosis factor (TNF)α, in the myeloid cell line, SR91, and in human peripheral blood monocytes (PBM). Additional experiments determined 6-sulfo N-acetyllactosamine (LacNAc)/Lewis x carbohydrate epitopes, as defined by the monoclonal antibody AG107, were induced on N and O-linked glycans of CD44 by TNFα in SR91 cells. This led to the hypotheses that the induction of the AG107 epitope on CD44 was associated with increased expression of a specific N-acetylglucosamine 6-0 sulfotransferase (GlcNAc6ST) and that the AG107 epitope was involved in the inflammatory process by mediating CD44-ligand interactions. Semi-quantitative reverse-transcriptase polymerase chain reaction revealed that TNFα upregulated the expression of GlcNAc6ST-1 in SR91 cells and GlcNAc6ST-1 and -4 in human PBM. In addition, GlcNAc6ST-1 was implicated in the synthesis of the AG107 epitope on CD44. Transcripts for GlcNAc6STs were not increased in mouse macrophages and human M1 macrophages exposed to pro-inflammatory mediators. By contrast, GlcNAc6ST- 1 and GlcNAcGST-4 transcripts were upregulated in human M2 macrophages incubated with TNFα. However, the AG107 epitope was not detected in these cells. Overall, this work suggests that GlcNAc6ST-1 and GlcNAc6ST-4 are involved the inflammatory process by generating 6-sulfo LacNAc/Lewis x epitopes on CD44 of human PBM. However, the results presented herein do not support a role for the AG107 epitope in TNFα-induced HA binding or L-selectin mediated rolling. In addition, GlcNAc6ST- 1 and GlcNAc6ST-4 may also play a role in functions associated with human M2 macrophages, such as Th2-mediated immunity and wound healing, but not by generating the AG107 epitope.

Journal of Economic Theory 98, 232260 (2001) Frictional Assignment. I. Efficiency1

This paper examines the two-sided matching problem where the agents on each side of the market are heterogeneous and the matching process is time consuming. This is cast in a labor market setting where workers of different skills match with different machine qualities. I characterize the efficient allocation and then show that it can be decentralized by a market mechanism. The efficient assignment is not always positively assortative, despite the fact that machine qualities and skills are complementary in production. To decentralize the efficient allocation, the market mechanism requires the firms to post wages and commit each machine quality to a particular skill. Implications on wage inequality are briefly examined. Journal of

Differential Maize Yield Hybrid Responses to Stand Density Are Correlated to Their Response to Radiation Reductions Around Flowering

Altered stand density affects maize yields by producing changes in both numerical yield components, kernel number per plant (KNP), and kernel weight (KW). Kernel number is determined by the accumulation of ear biomass during the flowering period, whereas KW is determined by the sink potential established during flowering and the capacity of the plant to fulfill this potential during effective grain filling. Here, we tested if different short shading treatments during different stages around flowering can help discriminate genotypic differences in eco-physiological parameters relevant for maize stand density yield response and associated yield components. Our specific objectives were to: (i) identify hybrids with differential shading stress response, (ii) explore shading effects over eco-physiological parameters mechanistically related to KNP and KW, and (iii) test if shading stress can be used for detecting differential genotypic yield responses to stand density. The objectives were tested using four commercial maize hybrids. Results indicated that KNP was the yield component most related to yield changes across the different shading treatments, and that the specific shading imposed soon after anthesis generated the highest yield reductions. Hybrids less sensitive to shading stress were those that reduced their plant growth rate the least and the ones that accumulated more ear biomass during flowering. Genotype susceptibility to shading stress around flowering was correlated to stand density responses. This indicated that specific shading stress treatments are a useful tool to phenotype for differential stand density responses of commercial hybrids.

THE CORRELATIVE ANALYSIS OF AMPLITUDE-TEMPORAL CHARACTERISTICS OF EVOKED POTENTIALS OF BRAIN CORTEX IN SPORTSMEN

The article considers the correlative analysis of amplitude-temporal characteristics of evoked potentials of brain cortex in sportsmen of playing kinds of sport and athletes at perception and processing of significant information “What” and “Where” in the brain cortex. The method of electroencephalography (Р300 methodology) was used to study the evoked potentials of the brain cortex. The statistical processing of data was realized using the statistical package MedStat. Kendall coefficient of correlation was used depending on data distribution, different from the normal values distribution. In the result of research there were revealed the high interconnections of latency of later components in sportsmen of both groups of examined persons at observation of significant stimuli “What” and “Where”. There was revealed the intensification of correlations of latency in frontal, central and temporal parts of the brain cortex. The correlations of amplitude of late components of biopotentials of the brain cortex were characterized with mean coefficients of interconnection mainly in sagittal central frontal and also parietal parts of cortex.
