Analysing consumer behavioural intention on sustainable organic food products

Population growth and improved global incomes have driven a significant increase in the production and consumption of food. Food consumption is known to have significant impacts on public health, individualities, and the environment and most importantly, food consumption is linked to environmental challenges like heightened pollution, scarcity of water, and CO2 emissions always been faced with grave environmental concerns and a massive surge in food intake assumes great significance. Consumers have a responsibility to protect the environment by choosing environmentally friendly products similar to organic food. This study modifies the TPB to model the consumer behavioural intention for organic food, using environmental concern, perceived value, and consumer familiarity as determinants. In the following, we explain how these well-established concepts are related to the three original constructs of the Theory of Planned Behaviour. The results of this study show that environmental concern, consumer perceived value of the product, and consumer familiarity (direct experience) with the product have a positive and significant effect on consumer behavioural intention for sustainable organic foods. In particular, this study finds that consumer environmental concern is the strongest predictor of purchase intention. This suggests that, in a sustainable organic food context, high levels of consumers' environmental concern increased their intention to purchase organic foods. Therefore, if a consumer is more concerned about environmental issues, the consumer will show a stronger intention to purchase sustainable organic food compared to consumers with lower environmental concerns.
Foreign Language Learning Anxiety in Virtual Classroom During the Covid-19 Pandemic: Tunisian Students of English as a Case Study

Foreign language learning anxiety (FLLA) is one of the most vastly studied variables in the field of foreign language learning (Horwitz, 2001). It is widely conceived as an obvious factor, in foreign language learning, which explained why some learners are more successful at learning and acquiring a foreign language than others though the settings and circumstances of learning are alike. The aim of this paper is to address the issue of foreign language learning anxiety that Tunisian students of English suffered from when they learn ‘behind the screen’ during the Covid-19 pandemic, by surveying 50 students enrolled in the Tunisian public universities and institutes. The foreign language classroom anxiety scale (FLCAS), developed by Horwitz, Horwitz, and Cope (1986), the most widely used scale for assessing general foreign language anxiety, is used in this research to inspect the anxiety level the learners face. Results of the survey reveal a significant relationship between foreign language anxiety and the academic level, whereas no significant relationship between gender and foreign language learning anxiety is marked. Investigating online learning in relation with foreign language learning anxiety can provide guidance and recommendations for teachers, course designers, pedagogues how to deal with learners behind the screen.
The Influence of Leadership Style, Organizational Culture, and Job Satisfaction on Employee Performance

The Environmental Agency is one of the local government agencies of Bantul Regency, which is in charge of preparing, implementing, supervising, controlling, and controlling all policies specific to the environment in Bantul Regency. This study aims to analyze and determine the influence of leadership style, organizational culture, and job satisfaction on employee performance. This research is quantitative with primary data. While obtaining data, research instruments that have been determined with distribution questionnaires, checks, or checklists are used for respondents. This study used a saturated sample where 105 employees used the entire population of members. The results showed that leadership style has a positive and significant effect on employee performance, organizational culture has a positive and significant impact on employee performance, and job satisfaction has a positive and significant impact on employee performance. The results of the f test stated that leadership style, organizational culture, and job satisfaction simultaneously affect employee performance Keywords : Leadership Style, Organizational Culture, And Job Satisfaction On Employee Performance
Relativistic transition probabilities and lifetimes of low-lying levels in ytterbium

Multiconfiguration Dirac-Fock calculations of E1, E2, M1 and M2 transition probabilities and lifetimes for the low-lying levels of neutral ytterbium are reported. For E1 transitions the valence-core electron correlations are also included in the core-polarization model. In particular, the lifetimes of the 6s6p1P1 and 3P1 states, when corrected for core polarization, are 4.78 ns and 1294 ns, respectively. The lifetime of the metastable 6s6p 3P2 state is calculated to be 14.5 s.
Linear recursive schemes associated with some nonlinear partial differential equations in one dimension and the Tau method

Standard compactness arguments for Volterra’s equation are used to prove the existence of the solution of some nonlinear partial differential equations in one dimension by associating them to linear recursive schemes. Sufficient conditions for the quadratic convergence of hyperbolic and parabolic types are given in this paper. By using a best approximation perturbation technique—the Tau Method—we show that these recursive schemes lead to accurate numerical approximations in concrete problems.
R-matrix Floquet theory of multiphoton processes: VI. The negative halide ions

The R-matrix Floquet approach is applied to study the negative and ions in a light field. Detachment rates are obtained for detachment processes involving up to three photons. The results obtained in the present approach are compared to other experimental and theoretical results. For two- and three-photon processes reasonable agreement with other calculations has been found, while for two-photon detachment the results agree with the experimental cross sections. The three-photon results are in less good agreement with experiment although the larger error bars make accurate comparisons more difficult. The changes in the detachment behaviour for these ions are compared to each other as well as to the detachment behaviour of .
Spectrophotometry: Revised Standards and Techniques

The telluric features redward of 6700 Å have been removed from the accurate spectrophotometric standards of Hamuy et al. to permit more reliable relative and absolute spectrophotometry to be obtained from CCD spectra. Smooth fluxes from 3300 to 10500 Å are best determined by dividing the raw spectra of all objects taken in a night by the raw spectrum of a “smooth” spectrum star before deriving the instrumental response function using the revised standard star fluxes. In this way the telluric features and any large instrumental variation with wavelength are removed from the raw data, leaving smooth spectra that need only small corrections to place them on an absolute flux scale. These small corrections with wavelength are well described by a low‐order polynomial and result in very smooth flux‐calibrated spectra.
Infrared observations of Nova Cygni 1975.

Infrared photometry from 1 to 20 microns and spectroscopy at about 2 microns are presented for Nova Cygni 1975 for the period from 2 days before to 1 yr after maximum light. The data can be explained by a simple model in which the expanding gas expelled during the explosion is always a plasma at approximately 10,000 K. Initially the gas is optically thick; this phase clearly defines the time of onset of the nova. Later, as the gas continues to expand, it becomes optically thin. The temporal dependence of the observed flux suggests that in this phase the expanding cloud is in the form of a shell. After about 300 days, long-wavelength emission which may be attributable to thermal reradiation from dust is observed.
Transparency and accountability of regional financial management: Accessibility of financial statements as a moderation

This study aims to provide empirical evidence of the influence of the Presentation of regional financial statements and regional financial accounting systems on the transparency and accountability of regional financial management, with the accessibility of financial statements as a moderation. The reason for this research is an employee who works in the finance department at a regional apparatus organization in Ternate City. The respondents in this study were employees who worked in the finance department, which totaled 67 respondents. The Sampling technique uses proportional random sampling. The data analysis model used to test and analyze the variables in this study uses multiple linear regression and Moderate Regression Analysis (MRA) to test research hypotheses with the help of the SPSS program. The results showed that the variables of the Presentation of regional financial statements and variables of regional financial accounting systems influenced the transparency and accountability of regional financial statements. The result found that the accessibility of regional financial statements could not moderate the influence of the Presentation of regional financial statements and the regional financial accounting system on the transparency and accountability of regional financial management.
Feature selection and structure specification in ultra-high dimensional semi-parametric model with an application in medical science

In this thesis, we consider the feature selection, model specification and estimation of the generalised semi-varying coefficient models (GSVCMs), where the number of potential covariates is allowed to diverge with the sample size. Based on the penalised likelihood approach and kernel smoothing method, we propose a penalised weighted least squares procedure to select the significant covariates, identify constant coefficients among the coefficients of the selected covariates, and estimate the functional or constant coefficients in GSVCMs. A computational algorithm is also proposed to implement the procedure. Our approach not only inherits many desirable statistical properties from the local maximum likelihood estimation and nonconcave penalised likelihood method, but also computationally attractive thanks to the proposed computational algorithm. Under some mild conditions, we establish the theoretical properties for the proposed procedure such as sparsity, oracle property and the uniform convergence rates of the proposed estimators. We also provide simulation studies to show the proposed procedure works very well when the sample size is finite. We then use the proposed procedure to analyse a real environmental data set, which leads to some interesting findings. Finally, we establish a classification method and show it can be used to improve predictive modelling for classify the patients with early inflammatory arthritis at baseline into different risk groups in future disease progression.

NATURAL CONVECTION IN A PARTITIONED TRAPEZOIDAL CAVITY HEATED FROM THE SIDE

Numerical results are reported for natural-convection heat transfer in partially divided trapezoidal cavities representing industrial buildings. Two thermal boundary conditions are considered. In the first, the left short vertical wall is heated while the right long vertical wall is cooled (buoyancy-assisting mode along the upper inclined surface of the cavity). In the second, the right long vertical wall is heated while the left short vertical wall is cooled (buoyancy-opposing mode along the upper inclined surface of the cavity). The effects of Rayleigh number, Prandtl number, baffle height, and baffle location on the heat transfer are investigated. Results are displayed in terms of streamlines, isotherms, and local and average Nusselt number values. For both boundary conditions, predictions reveal a decrease in heat transfer in the presence of baffles, with its rate generally increasing with increasing baffle height and Pr. For a given baffle height, greater decrease in heat transfer is generally obtained with baffles located close to the short vertical wall.
Market Reactions to Emergency Community Activity Restrictions Policy

This research uses the event study method to test the reaction of capital markets before and after the announcement of the Emergency Community Activity Restrictions (PPKM) policy. The observation period includes 7 days before and 7 days after the event. By using purposive sampling method, the research sample amounts to 29 stocks of the hotel, restaurant, and tourism companies listed on the Indonesia Stock Exchange. The hypothesis is tested with Paired Samples T-Test for those with normal distribution and Wilcoxon Signed Ranks Test for those with no normal distribution. The results showed that there was a difference in average trading volume activity. While average abnormal return and average security return variability did not have significant differences around the announcement. This research implies that stock investors need to consider information about government policies or other non-economic events to appropriately sort out relevant information to sell or maintain stocks under the risks and returns expected by investors.

A Bayesian Model for Estimating Census Undercount, Taking Emigration Data from Foreign Censuses *

The new method of measuring net undercount in a census of population is a variant of demographic analysis and is founded in the belief that the most reliable counts of people are the counts of births and deaths. It has been applied to the 1991 census of England and Wales (E&W). The method has two distinctive features. The first is that it bases its estimates of numbers of emigrants on figures of persons born here and recorded as residents in the 1990–91 censuses of other countries. The corresponding data on immigrants are taken from our own census. The method does not therefore require the data on migratory flows that are an essential component of conventional demographic analysis. The second feature is the Bayesian approach in which (1) each of 30 uncertain elements in the calculations is given an a priori error distribution and (2) three empirical constraints are imposed on the sex‐age profile of percentage net undercount. This, in conjunction with a Monte Carlo process, generates an error distribution for net undercount. These merits of the method are offset by the demerit that the calculations must await results from the censuses of the other countries in which substantial numbers of our emigrants reside.
A synthesis of magnetospheric substorm models

Three decades of research in magnetospheric substorms has not led to a general consensus view of the substorm process. Several substorm models, mostly phenomenological, are presently under consideration. These competing models, each being justifiable on the basis of certain features of a substorm, have major differences as well as similarities among them. A synthesis substorm model is desirable, as first suggested by Siscoe (1986). In this paper we construct a coherent description of substorm development by extracting some important components from these existing models. The scenario of the synthesis model includes the ionospheric influence on substorm expansion onset, current disruptions leading to convection surges and tailward propagating rarefaction waves, wave-induced precipitation, local time expansion of the disturbance region via velocity-shear-related instabilities, plasma sheet heating by resonant absorption of hydromagnetic waves, and the formation of magnetic reconnection domains. This synthesis represents one possible way to integrate the different existing models coherently.
An explicit optimal intervention policy for a deterministic epidemic model

Optimal policies involving the removal of susceptible individuals from the population at risk are derived for a deterministic epidemic model with a non‐standard infection rate function. Denoting by y the number of infective individuals and by x the number of susceptible individuals in the population, we replace the classical Kermack–McKendrick infection rate function βxy (for some constant β) with βxy/(x+y). This modified model has been studied by various previous authors, including derivation of an optimal policy when intervention consists of isolation of infective individuals from the susceptible population. For the less tractable situation when intervention consists of removal of susceptible individuals, we show that the optimal policy is to intervene with maximal effort when y⩾Ax with x, y>0, and not to intervene otherwise, for some constant A∈[0, ∞] whose value depends upon the parameters of the model.

On streamwise vortices in a turbulent wall jet that flows over a convex surface

Flow visualization and correlation measurements revealed the existence of large streamwise vortices in a turbulent wall jet that is attached to a circular cylinder. These coherent structures were not to be found near the nozzle, nor were they artificially triggered, thus the vortices could be a product of centrifugal instability. The existence and scale of this large-scale coherent motion were corroborated by stability analysis applied to the measured mean flow.
An elementary approach to the 3D Navier-Stokes equations with Navier boundary conditions: Existence and uniqueness of various classes of solutions in the flat boundary case

We study with elementary tools the stationary 3D Navier-Stokes equations in a flat domain, equipped with Navier (slip without friction) boundary conditions. We prove existence and uniqueness of weak, strong, and very-weak solutions in appropriate Banach spaces and most of the result hold true without restrictions on the size of the data. Results are partially known, but our approach allows us to give rather elementary and self-contained proofs.
Kinematics and Luminosity Function of Dwarf Populations in Three Areas of the Calán-ESO Proper-Motion Catalog

We have completed the analysis of a sample of 112 stars in the solar neighborhood taken from the statistically complete Calán-ESO catalog. From medium-resolution spectroscopy we classified every star, both by direct comparison with spectroscopic standards and by using spectral indices. The latter also allowed discrimination between main-sequence (MS) dwarfs and subdwarfs. Several useful spectral type versus color relations were obtained from CCD photometry of the sample (observed magnitudes were dereddened). Distances and absolute magnitudes were determined. From measured radial velocities and proper motions, we determined the kinematics [Galactocentric velocity components (U, V, W)], which allowed the classification of each star as belonging to the disk or halo population. Luminosity functions (LFs) were then obtained using the 1/Vmax method for the different populations. The maximum in the LF for MS dwarfs was found to be near MV = 12.5 ± 0.5, in accord with previous determinations. On the other hand, we found an increase in the LF of the subdwarf at its faint end, which is in strong disagreement with determinations by other authors. A mass density of MS dwarfs of ∼0.047 ± 0.021 M⊙ pc-3 was derived, while the contribution of subdwarfs was found to be negligible.
Distributed matrix completion and robust factorization

If learning methods are to scale to the massive sizes of modern datasets, it is essential for the field of machine learning to embrace parallel and distributed computing. Inspired by the recent development of matrix factorization methods with rich theory but poor computational complexity and by the relative ease of mapping matrices onto distributed architectures, we introduce a scalable divide-and-conquer framework for noisy matrix factorization. We present a thorough theoretical analysis of this framework in which we characterize the statistical errors introduced by the "divide" step and control their magnitude in the "conquer" step, so that the overall algorithm enjoys high-probability estimation guarantees comparable to those of its base algorithm. We also present experiments in collaborative filtering and video background modeling that demonstrate the near-linear to superlinear speed-ups attainable with this approach.
Taylor vortices in annular spherical flow at large aspect ratios

Motivated by recent theoretical and experimental work, we numerically investigate spherical Couette flow with a view to obtaining for the first time Taylor vortices at large aspect ratios σ such as 0.38, 0.42, and 0.48. It is found that Taylor vortices can exist, stable or time-dependent, in a range of Reynolds numbers [Re1, Re2] and their formation depends on the aspect ratio, on the imposition of various rotationary conditions on the boundaries, on the history of the flow and on the rate at which energy is transferred into the fluid to its final value. With increasing σ the range [Re1, Re2] manifests a clear tendency to shorten.
Comparison and regularity results for degenerate elliptic equations related to Gauss measure

This article deals with a Dirichlet problem relative to a linear elliptic equation with zero-order terms, whose ellipticity condition is given in terms of the function ν(x)ϕ(x), where is the density of Gauss measure, ν(x) is a nonnegative integrable function. Using the notion of rearrangement with respect to Gauss measure, we prove a comparison result with a problem of the same type defined in a half space, with data depending only on the first variable. Also, some regularity results for the solutions in Lorentz–Zygmund spaces are obtained by us.
Integrated Sculptured Thin Films

We have demonstrated the integration of various morphologies generated by dynamic oblique deposition, during which the deposition angle and the azimuth of the substrate are varied. The layers with zigzag, helicoidal and cylindrical columns have been successfully stacked on a substrate without using any etching process. In addition, the uniform and flat layer is formed on porous layers by a gradual change in the deposition geometry. Therefore, shape-related physical anisotropies and the chemical activity due to high porosity can be integrated in one thin film, making it applicable to devices such as solar cells and chemical sensors.
An Exploration of the Robustness of Four Test Equating Models

This monte carlo study explored how four com monly used test equating methods (linear, equipercen tile, and item response theory methods based on the Rasch and three-parameter models) responded to tests of different psychometric properties. The four methods were applied to generated data sets where mean item difficulty and discrimination as well as level of chance scoring were manipulated. In all cases, examinee abil ity was matched to the level of difficulty of the tests. The results showed the Rasch model not to be very robust to violations of the equal discrimination and non-chance scoring assumptions. There were also problems with the three-parameter model, but these were due primarily to estimation and linking prob lems. The recommended procedure for tests similar to those studied is the equipercentile method.
