Assessment for learning in English and mathematics: a comparison

Research in the area of assessment for learning (AfL) has largely focused on generic approaches and strategies, applicable to teaching and learning in all subject areas. In this article, we address the issue of subject-specific approaches. We examine two lessons, one English and one mathematics, and we discuss the form of assessment for learning in the context of these two subjects. English and mathematics are often thought of as contrasting disciplines, typifying the arts/sciences split in education and there are significant differences in the social norms and the structure of knowledge in each subject. This article undertakes a comparison of the lessons in order better to understand how these significant differences affect the realization of formative assessment in the classroom, and in doing so finds much common ground which might be the starting point for future dialogue between the disciplines.
THE DETERMINANTS OF CONSUMERS' ONLINE SHOPPING BEHAVIOUR: AN EMPIRICAL ASSESSMENT

The study focuses on the effect of four primary characteristics derived from the literature, including trust, product variety, convenience, and privacy, so as to identify how customer purchasing behavior reflects online shopping trends. The researcher used quantitative research approach to documents responses of respondents. Students attending Thal university & Sargodha university are mostly those engaged in business programme at respective institutions, such as the Department of Business Administration and Noon Business school was accessed to collect the data through questioner. The researchers use structural equational model to test hypothesis of current research, analyze the results and reach the desired conclusion and thus recommending some suggestions. According to the findings of statistical analysis of data, customers trust, product variety, convenience and privacy has statistically significant relationship with the online consumer behaviour. This conclusion is vital for the marketers to facilitate the usage of online shopping platforms in order to save more time and attract more people to buy items online.
AN EXPERIMENTAL STUDY OF HELICON WAVE PROPAGATION IN A GASEOUS PLASMA

The results of an experimental study of helicon wave propagation in a partially ionized cylindrical plasma are reported. Conditions were chosen so that the phase velocity of the wave was independent of both the electron and ion mass. The phase velocity, the attenuation and the structure of the plasma magnetic fields are compared with the theoretical treatment of Klozenberg, McNamara and Thonemann in 1964. The agreement is satisfactory. In particular, evidence is presented which supports the anomalously high attenuation due to surface currents which the above theory predicts.
The use of Lie transformation groups in the solution of the coupled diffusion equation

The solutions of coupled, linear and nonlinear, diffusion equations in a semi-infinite medium, are derived using the method of continuous one-parameter point symmetry group invariants. Initially, conditions for both classical and non-classical Lie group invariants are developed and solutions are derived corresponding to linear coupled diffusion. The non-classical invariants are shown to be expressible in terms of a linear parabolic operator. In addition, solutions corresponding to constant, impulse and sinusoidally time varying condition are derived from the equations determining classical group invariance. Nonlinear cases are also considered. The classical symmetry groups for any form of diffusion matrix are presented. In addition, the point source solution for a power-law form governing the diffusion matrix is derived. It is a natural extension of the scalar analogue.
Detecting Mispronunciations of Non-Native (L2) Post-Graduate Students of English Language Education in Indonesia

Speaker’s good pronunciation makes his/her listener comfortable, and confident to participate in the conversation and his/her mispronunciations bring implications to the listener’s awareness and involvement with the message spoken. The research was aimed at detecting the mispronunciations made by 70 non-native (L2) post-graduate students who were enrolled in the English department and were also school teachers in Greater Jakarta (including Jakarta, Bogor, Depok, Tangerang, and Bekasi [or commonly shortened as Jabodetabek]). They were given English texts to read, and recorded, and a semi-structured interview was applied. Error analysis was employed to check mispronunciations. The results showed that 43 students (61%) made mispronunciations and 27 (39%) didn’t. Mispronunciation was found on vowels by 4 students (5.71%), on consonants by 5 (7.14%), on diphthongs by 3 (4.28%), and on consonant clusters by 14 (20%). Most of the students made intralingual and global errors.
A comparison of negative and positive streamers in mineral oil at large gaps

The propagation of negative streamers in mineral transformer oil is investigated in large point-plane gaps up to 35 cm, under impulse voltage. Basic features of streamers are obtained: velocity, stopping length, propagation voltage, electrical charge, photographs of the emitted light. Many features of negative streamers resemble those already observed in positive polarity under similar conditions. The voltage required to initiate fast streamers (velocity higher than 50 km s-1) is identical in both polarities. The variation of propagation voltage versus distance and streak photographs both suggest that conduction mechanisms within long gaseous streamer channels are identical in positive and negative polarities. Some characteristics are however different: in negative polarity a higher voltage is required for the onset of propagation, propagating streamer heads emit more light and their velocity is lower. These differences are due to different propagation mechanisms occurring at the streamer heads. These mechanisms as well as the implications for practical high voltage insulation are discussed.
Trans-Fast MHD Winds in a Pulsar Magnetosphere

We consider the problem of how a pulsar wind dominated by electro-magnetic energy converts itself into a kinetic energy-dominated wind, that is required by magnetohydrodynamical (MHD) models of interaction between the pulsar and the nebula. It is known that stationary, ideal-MHD wind models based on radial configurations are incapable of explaining the energy conversion from the electro-magnetic energy to the plasma's kinetic energy. For non-radial field geometries, we consider a detailed analysis of the critical conditions of trans-fast MHD winds and discuss the effects of the magnetic field on the wind acceleration. Although the flow properties associate with the magnetic flux tube divergence, we survey the acceptable ranges of the wind parameters as a pulsar wind. Further, we demonstrate the Crab pulsar wind with a magnetic flux tube diverging as oc x~ 0A . We see that the rapid acceleration is caused by a nearby Alfven point; the velocity is almost terminated within several thouthand times of the fast magnetosonic point; thus, the kinetic energy-dominated wind is realized.

Experimental and Numerical Investigation of the Precessing Helical Vortex in a Conical Diffuser, With Rotor–Stator Interaction

The flow unsteadiness generated in a swirling apparatus is investigated experimentally and numerically. The swirl apparatus has two parts: a swirl generator and a test section. The swirl generator includes two blade rows, one stationary and one rotating, is designed such that the emanating flow resembles that of a Francis hydro turbine operated at partial discharge. The test section consists of a conical diffuser similar to the draft tube cone of a Francis turbine. A new control method based on a magneto rheological brake is employed in the rotating section, runner, in order to produce several swirling flow regimes. The LDV measurements are performed along three survey axes in the test section. The measured mean velocity components and its fluctuating parts are used to validate the results of unsteady numerical simulations, conducted using the FOAM-extend-3.0 CFD code. A dynamic mesh is used together with the sliding General Grid Interfaces (GGI) to mimic the effect of the rotating runner. The delayed detached eddy simulation method, conjugated with the Spalart-Allmaras turbulence model (DDES-SA), is applied to achieve a deep insight about the ability of this advanced modeling technique and the physics of the flow. The RNG k-epsilon model is also used to represent state-of-the art of industrial turbulence modeling. Both models predict the mean velocity reasonably well while DDES-SA presents more realistic flow features at the highest and lowest rotational speeds. The highest level of turbulence occurs at the highest and lowest rotational speeds which DDES-SA is able to predict well in the conical diffuser. The special shape of the blade plays more prominent role at lower rotational speeds and creates coherent structures with opposite sign of vorticity. The vortex rope is captured by both turbulence models while DDES-SA presents more realistic one at higher rotational speeds.
Cost-Effectiveness of Bariatric Surgery in Tunisia

Purpose Obesity is a growing global issue with evidence linking it to an increase in loss of disease-free years, reduced quality of life, increased mortality, and additional economic burden. This study sought to establish the cost-effectiveness of gastric bypass and sleeve gastrectomy, compared to conventional therapy in patients with obesity, from a Tunisian healthcare payor perspective. Patients and Methods A Markov model compared lifetime costs and outcomes of bariatric surgery with conventional treatment among patients with body mass index (BMI) ≥ 40 kg/m2, BMI ≥ 35 kg/m2 with obesity-related co-morbidities (Group 1), or BMI ≥ 35 kg/m2 with type 2 diabetes mellitus (T2DM) (Group 2). Inputs were sourced from the Tunisian Health Examination Survey, local clinician data and literature sources. Health states were associated with different cost and utility decrements. Changes in body mass index, systolic blood pressure, lipid ratio and diabetes remission rates were modelled on a yearly basis. The incremental cost-effectiveness ratio (ICER), quality-adjusted life years (QALYs) and net monetary benefit (NMB) were key outcomes. Sensitivity and scenario analyses were performed to test the model’s robustness. Results The model showed that the benefits of bariatric surgery were favorable compared to conventional treatment, with an ICER of 1844 TND/QALY in Group 1 patients and 2413 TND/QALY in Group 2 patients. Bariatric surgery resulted in a QALY gain of 3.26 per patient in Group 1 and a gain of 1.77 per patient in Group 2. At a willingness to pay threshold of 31,379 TND/QALY, the incremental NMB was 96,251 TND and 51,123 TND for Group 1 and Group 2, respectively. Conclusion From the Tunisian healthcare payor perspective, bariatric surgery is cost-effective for patients with obesity and those with T2DM and obesity-related comorbidities. These findings may have impact on future decision-making on funding and reimbursement of bariatric surgery in Tunisia.
Rarefaction-driven Rayleigh–Taylor instability. Part 1. Diffuse-interface linear stability measurements and theory

Theory and experiments are reported that explore the behaviour of the Rayleigh–Taylor instability initiated with a diffuse interface. Experiments are performed in which an interface between two gases of differing density is made unstable by acceleration generated by a rarefaction wave. Well-controlled, diffuse, two-dimensional and three-dimensional, single-mode perturbations are generated by oscillating the gases either side to side, or vertically for the three-dimensional perturbations. The puncturing of a diaphragm separating a vacuum tank beneath the test section generates a rarefaction wave that travels upwards and accelerates the interface downwards. This rarefaction wave generates a large, but non-constant, acceleration of the order of $1000g_{0}$ , where $g_{0}$ is the acceleration due to gravity. Initial interface thicknesses are measured using a Rayleigh scattering diagnostic and the instability is visualized using planar laser-induced Mie scattering. Growth rates agree well with theoretical values, and with the inviscid, dynamic diffusion model of Duff et al. (Phys. Fluids, vol. 5, 1962, pp. 417–425) when diffusion thickness is accounted for, and the acceleration is weighted using inviscid Rayleigh–Taylor theory. The linear stability formulation of Chandrasekhar (Proc. Camb. Phil. Soc., vol. 51, 1955, pp. 162–178) is solved numerically with an error function diffusion profile using the Riccati method. This technique exhibits good agreement with the dynamic diffusion model of Duff et al. for small wavenumbers, but produces larger growth rates for large-wavenumber perturbations. Asymptotic analysis shows a $1/k^{2}$ decay in growth rates as $k\rightarrow \infty$ for large-wavenumber perturbations.
Magnitude and Factors Associated with Cytopenia Among Children on Highly Active Antiretroviral Therapy at Hawassa University College of Medicine and Health Science, Sidama Region, Southern Ethiopia

Background The most common abnormality in HIV-infected children is cytopenia, a hematological complication characterized by a decline in any of the blood cell lines. It is associated with a higher risk of morbidity and mortality. Therefore, this study aimed to assess the prevalence and associated factors of cytopenia among HIV-positive children on highly active antiretroviral therapy (HAART). Methods Hospital-based cross-sectional study design was conducted on HIV-positive children on HAART from July to September 2020. Socio-demographic and clinical characteristics of the study participants’ data were collected using a structured questionnaire. Hematological parameters from the blood sample were analyzed using Ruby Cell-Dyne 300 hematology auto-analyzer. The data were analyzed using SPSS version 20. Logistic regression was used to assess the predictors of cytopenia among the study participants. P-values of less than 0.05 are considered statistically significant. Results Two hundred seventy-three HAART-experienced children were enrolled in this study, and 50.9% were females. At baseline, 40.7% of children were anemic. The overall magnitude of cytopenia among the study participants was 26.7%. The prevalence of anemia, thrombocytopenia, leucopenia and neutropenia among children was 11.4%, 4.0%, 14.3%, and 18.3%, respectively. Patients with an undetectable viral load (AOR = 0.5, CI = 0.3–0.9) are 50% less likely to report cytopenia. HAART-experienced children living in rural areas are more likely to develop cytopenia (AOR = 2.6, CI = 1.3–5.2) than those living in urban areas. Conclusion Hematologic abnormalities are common problems among children on highly active antiretroviral therapy. Therefore, routine investigation of hematological and immunological changes following appropriate therapeutic interventions is recommended.
Is innovativeness influenced by proactiveness and risk-taking? Evidence from Poland based on structural equation modelling

This article focuses on entrepreneurial orientation in a firm’s internationalisation process, which is one of the leading research trends in international entrepreneurship. The objective of the study is to verify the relationship between proactiveness, risk-taking and innovativeness as components of the entrepreneurial orientation of internationalised Polish firms. The article answers the main research question of how proactiveness and risk-taking influence innovativeness as an interrelated three-dimensional construct of entrepreneurial orientation. We present the results of a study based on a stratified sampling of 355 internationalised Polish firms. Structural equation modelling (CB-​SEM) demonstrated a positive effect of proactiveness (PROACT) and risk-taking (RISK) on innovativeness (INNO) as an interrelated three-dimensional construct of entrepreneurial orientation. Moreover, the level of proactiveness (PROACT) and risk-taking (RISK) explained 32% of the variation in innovativeness (INNO), which is high in social sciences, including business studies.
Cardiovascular Risk Among Patients with Controlled and Uncontrolled Type 2 Diabetes: A Sub-Cohort Analysis from the Heart Health Promotion (HHP) Study

Objective This study aimed to estimate the risk of cardiovascular disease (CVD) among patients with and without diabetes mellitus (DM) using the Framingham risk score (FRS) and to investigate the effect of DM control on CVD risk. Methodology A total of 2432 participants who had their glycosylated hemoglobin (HbA1c) measured within the last three months were included in this study. The study cohort was divided into three categories: non-diabetic, participants with controlled DM (HbA1c<7%), and uncontrolled DM (HbA1c≥7%). The World Health Organization’s stepwise approach to chronic disease risk factor Surveillance-Instrument v2.1 was used in this study to collect the anthropometric and biochemical measurements. The Framingham Coronary Heart Risk Score (FRS) was used to calculate the 10-year cardiovascular risk (CVR). The groups were compared concerning the prevalence of metabolic, socioeconomic, and cardiac risks. Results Out of 2432 participants, 149 had controlled DM (6.1%), 286 had uncontrolled DM (11.8%), and 1997 participants were normoglycemic (82.1%). Compared to healthy participants, diabetic participants showed more high-risk characteristics across all CVR parameters. Uncontrolled diabetic patients had a graver laboratory and clinical profiles compared to the controlled DM group. As measured by FRS, nearly half of patients with controlled DM (49.9%) and two-thirds of patients with uncontrolled DM (63.3%) were classified as intermediate and high-risk compared to 4.6% of the healthy participants. Compared to healthy participants, patients with controlled DM showed a threefold increased CVR (OR = 3.02, 95% C.I. = 1.41–7.24) while this risk catapulted to 13 times among those with uncontrolled DM (OR = 13.57, 95% C.I. = 6.99–26.36). Conclusion Participants with DM are at moderate to high CVR. Individuals with uncontrolled DM showed higher CVR profiles as measured by FRS and have a higher prevalence of obesity, unhealthy diet, and physical inactivity.
Spatiotemporal characteristics of high winds in Jilin Province during 1982–2021

High winds are a type of catastrophic weather characterized by wind speeds over 10.8 m·s−1, occurring in all seasons, and have become more frequent, impacting crop growth, agricultural production and quality of life. It is crucial to understand the spatial and temporal distribution patterns of high winds, as well as their speed and other characteristics, for logical planning of agricultural production and the creation of disaster resilience measures. This study applied the climate tendency, accumulative anomalies, theory of run, Mann–Kendall trend and Theil–Sen median to analyse the spatial and temporal distribution characteristics of the average wind speed and high wind days in Jilin Province, the probability of occurrence of high winds of various magnitudes in different eras, and the gale concentration degree (GCD) throughout Jilin Province for a total of 40 years from 1982 to 2021. The average wind speed and number of high wind days in Jilin Province have decreased over the past 40 years, and this trend has slowed over time. The average GCD in Jilin Province has shown an increasing trend over the last 40 years, with the average GCD being highest in Liouhe and lowest in Linjiang. In general, level six high winds were the main wind hazard level in Jilin Province, with the highest frequency occurring in different seasons and decades. In addition, the occurrence of high wind days is affected by global climate change and different underlying surfaces, which leads to maize and yield reduction. Research on the spatiotemporal distribution of high winds can provide important suggestions for the prevention and management of high wind disasters.
A note on radiality of solutions of P-laplacian

In this note we consider the p-laplacian equation (see equation (1) below) in radial domains (a hall or all RN). We prove that any positive solution of this equation, assuming suitable boundary data, is radial if it satisfies the additional condition u(x) < 0 if x < 0.
Olfactometric testing as a method for assessing odour nuisance of biogas plants processing municipal waste

: Biogas plants processing municipal waste are very important investments from the point of view of waste management and also the sustainable development of urban infrastructures. They may also have a potentially negative impact on the environment in the form of odour emission. Olfactometry is the main method for odour impact assessment. Field olfactometry allows for performing a wide range of tests, the results of which are practically instantaneous. The purpose of this work is to provide a tool for assessing the odour impacts of municipal management facilities,
Estimating correlation and covariance matrices by weighting of market similarity

We discuss a weighted estimation of correlation and covariance matrices from historical financial data. To this end, we introduce a weighting scheme that accounts for the similarity of previous market conditions to the present situation. The resulting estimators are less biased and show lower variance than either unweighted or exponentially weighted estimators. The weighting scheme is based on a similarity measure that compares the current correlation structure of the market to the structures at past times. Similarity is then measured by the matrix 2-norm of the difference of probe correlation matrices estimated for two different points in time. The method is validated in a simulation study and tested empirically in the context of mean–variance portfolio optimization. In the latter case we find an enhanced realized portfolio return as well as a reduced portfolio risk compared with alternative approaches based on different strategies and estimators.
