Form and Function: A Study on the Distribution of the Inflectional Endings in Italian Nouns and Adjectives
Authors: Pescuma Valentina Nicole , Zanini Chiara , Crepaldi Davide , Franzon Francesca
Published: October 2021

Inflectional values, such as singular and plural, sustain agreement relations between constituents in sentences, allowing sentence parsing and prediction in online processing. Ideally, these processes would be facilitated by a consistent and transparent correspondence between the inflectional values and their form: for example, the value of plural should always be expressed by the same ending, and that ending should only express plural. Experimental research reports higher processing costs in the presence of a non-transparent relation between forms and values. While this effect was found in several languages, and typological research shows that consistency is far from common in morphological paradigms, it is still somewhat difficult to precisely quantify the transparency degree of the inflected forms. Furthermore, to date, no accounts have quantified the transparency in inflection with regard to the declensional classes and the extent to which it is expressed across different parts of speech, depending on whether these act as controllers of the agreement (e.g., nouns) or as targets (e.g., adjectives). We present a case study on Italian, a language that marks gender and number features in nouns and adjectives. This work provides measures of the distribution of forms in the noun and adjective inflection in Italian, and quantifies the degree of form-value transparency with respect to inflectional endings and declensional classes. In order to obtain these measures, we built Flex It, a dedicated large-scale database of inflectional morphology of Italian, and made it available, in order to sustain further theoretical and empirical research.
Examining Job Complexity on Job Crafting Within Conservation of Resources Theory: A Dual-Path Mediation Model
Authors: Bai Jing Yi , Tian Qing , Liu Xia
Published: October 2021

This study examined the different ways in which job complexity influences employees’ job crafting. Specifically, we draw on conservation of resources (COR) theory to hypothesize that job complexity is positively related to approach crafting via work engagement (i.e., resource gain process). At the same time, job complexity may also induce employees to engage in avoidance crafting (i.e., resource loss process) as employee energy resources are depleted. Our data consist of 251 employees working in Macau. We used structural equation modeling (SEM) in Mplus software to test the proposed hypotheses. Our findings confirm that job complexity has differential effects on approach and avoidance crafting through work engagement and energy depletion. These findings highlight the importance of costs and benefits of job complexity and the importance of resources in the employees’ job crafting process. We discuss the practical implications for modern organizations in which complex jobs are prevalent.

Authors: Liu Qian , Fung Daryl L. X. , Lac Leann , Hu Pingzhao
Published: October 2021

Background: The outbreak of the novel coronavirus disease 2019 (COVID-19) has been raging around the world for more than 1 year. Analysis of previous COVID-19 data is useful to explore its epidemic patterns. Utilizing data mining and machine learning methods for COVID-19 forecasting might provide a better insight into the trends of COVID-19 cases. This study aims to model the COVID-19 cases and perform forecasting of three important indicators of COVID-19 in the United States of America (USA), which are the adjusted percentage of daily admitted hospitalized COVID-19 cases (hospital admission), the number of daily confirmed COVID-19 cases (confirmed cases), and the number of daily death cases caused by COVID-19 (death cases).

Materials and Methods: The actual COVID-19 data from March 1, 2020 to August 5, 2021 were obtained from Carnegie Mellon University Delphi Research Group. A novel forecasting algorithm was proposed to model and predict the three indicators. This algorithm is a hybrid of an unsupervised time series anomaly detection technique called matrix profile and an attention-based long short-term memory (LSTM) model. Several classic statistical models and the baseline recurrent neural network (RNN) models were used as the baseline models. All models were evaluated using a repeated holdout training and test strategy.

Results: The proposed matrix profile-assisted attention-based LSTM model performed the best among all the compared models, which has the root mean square error (RMSE) = 1.23, 31612.81, 467.17, mean absolute error (MAE) = 0.95, 26259.55, 364.02, and mean absolute percentage error (MAPE) = 0.25, 1.06, 0.55, for hospital admission, confirmed cases, and death cases, respectively.

Conclusion: The proposed model is more powerful in forecasting COVID-19 cases. It can potentially aid policymakers in making prevention plans and guide health care managers to allocate health care resources reasonably.
The Intentional Stance Test-2: How to Measure the Tendency to Adopt Intentional Stance Towards Robots
Authors: Spatola Nicolas , Marchesi Serena , Wykowska Agnieszka
Published: October 2021

In human-robot interactions, people tend to attribute to robots mental states such as intentions or desires, in order to make sense of their behaviour. This cognitive strategy is termed “intentional stance”. Adopting the intentional stance influences how one will consider, engage and behave towards robots. However, people differ in their likelihood to adopt intentional stance towards robots. Therefore, it seems crucial to assess these interindividual differences. In two studies we developed and validated the structure of a task aiming at evaluating to what extent people adopt intentional stance towards robot actions, the Intentional Stance task (IST). The Intentional Stance Task consists in a task that probes participants’ stance by requiring them to choose the plausibility of a description (mentalistic vs. mechanistic) of behaviour of a robot depicted in a scenario composed of three photographs. Results showed a reliable psychometric structure of the IST. This paper therefore concludes with the proposal of using the IST as a proxy for assessing the degree of adoption of the intentional stance towards robots.

The aim of this paper is to describe the most common errors made by
Ukrainian- and Russian-speaking people while learning infl ection of numerals
for person and their causes. The applied comparative method permits a closer
look at formal and syntactic relations as well as collocations of numerals and
specifi c lexeme classes (this regards primarily agreement between cardinal
numbers and masculine personal verbs, compound structures with the numeral
jeden (one) and numerals showing adjectival infl ection). This study concentrates
on a comparison of cardinal and ordinal numbers in Ukrainian, Russian and
Polish, which allowed an analysis of the causes of errors made while learning the
infl ection of numerals by Ukrainian- and Russian-speaking students.
Tożsamość języka jidysz
Authors: Geller Ewa
Published: October 2021

The object of this paper is an attempt to describe the complex identity of the
Yiddish language itself and its users. Poland and the Polish language have played
a signifi cant role in both these aspects. Part one is a sociolinguistic overview of
the history of crystallisation of Yiddish in the historical territory of Poland as the
autonomous language of the national culture of Central and Eastern European
Jews. Its fate after the Holocaust of European Jews is also described here. Part
two is dedicated to problems with the genetic classifi cation of Yiddish due to the
language-forming processes accompanying its development. Yiddish is classifi ed
among mixed languages, since it came into existence as a result of Hebrew–
Slavic–Germanic language contacts. Therefore, this part pays special attention
to the explanation of the mixed nature of this language system and the role
of Polish as an important contact language infl uencing the fi nal shape of the
contemporary Yiddish language

Published: October 2021

This study aimed to characterize the susceptibility profile to antibiotics and biofilm formation of Gram-negative bacterial isolates obtained from the oral cavity of the black-and-white ruffed lemur (Varecia variegata). From eight individuals from a zoo located in Portugal, samples of the oral microbiota were collected with sterile swabs and then placed in closed tubes with a transport medium. Culture was carried out for media of Gram-negative bacteria. Twenty-two isolates were obtained and subjected to susceptibility tests to twenty-five antimicrobial agents belonging to seven different classes. All tested isolates demonstrated resistance to, at least, one antibiotic, and it was possible to observe multidrug resistance in 11 of the 22 isolates (50%). It should be noted that an isolate showed phenotypic resistance to imipenem, an antibiotic for exclusive use in a hospital environment. All the isolates showed an increasing ability of biofilm formation over time. The obtained results show that wild mammals in captivity could be reservoirs and potential sources of multi-resistant pathogens. In view of this fact and considering the One Health concept, it will be advisable to establish local monitoring programs worldwide that benefit and protect human, animal and environmental health.

Authors: Wu Tienhua , Tien Kuang-You , Hsu Wei-Chih , Wen Fu-Hsiang
Published: October 2021

Information security awareness (ISA) has become a vital issue, as security breaches often attributed to humans lead to losses for individuals and organizations. Information security (IS) education may be an effective strategy to improve students’ ISA; however, studies associated with the relationships between teaching effects and information security learning are few. This study adopted gamification practice and examined its effect on students’ ISA knowledge enhancement, attitude and intention of security compliance, and willingness for continuous IS education. This study also examined the gender difference in a gamified learning system. One hundred ten undergraduates participated in a quasi-experimental study. The results indicated that students within a gamified class performed better than students within a lecture-based instructional group. We found significant gamification effects on the three security focus areas of password management, Internet use, and information handling. Gamification did not significantly impact the attitude and intention of participants’ security compliance and students’ willingness for continuous IS learning. Gender difference in the effect of gamification on ISA knowledge enhancement was not observed as well. The research provides theoretical and practical contributions by incorporating gamification into IS learning and suggests gamification as an effective means to enhance students’ knowledge acquisition in an engaging, timely, economical, and repeated manner.

Published: October 2021

The solution of the motion equation for a structural system under prescribed loading and the prediction of the induced accelerations, velocities, and displacements is of special importance in structural engineering applications. In most cases, however, it is impossible to propose an exact analytical solution, as in the case of systems subjected to stochastic input motions or forces. This is also the case of non-linear systems, where numerical approaches shall be taken into account to handle the governing differential equations. The Legendre–Galerkin matrix (LGM) method, in this regard, is one of the basic approaches to solving systems of differential equations. As a spectral method, it estimates the system response as a set of polynomials. Using Legendre’s orthogonal basis and considering Galerkin’s method, this approach transforms the governing differential equation of a system into algebraic polynomials and then solves the acquired equations which eventually yield the problem solution. In this paper, the LGM method is used to solve the motion equations of single-degree (SDOF) and multi-degree-of-freedom (MDOF) structural systems. The obtained outputs are compared with methods of exact solution (when available), or with the numerical step-by-step linear Newmark-β method. The presented results show that the LGM method offers outstanding accuracy.
Novel Multiple-Image Encryption Scheme Based on Coherent Beam Combining and Equal Modulus Decomposition
Authors: Li Wei , Yan Aimin , Zhang Hongbo
Published: October 2021

In our research, we propose a novel asymmetric multiple-image encryption method using a conjugate Dammann grating (CDG), which is based on the coherent beam combining (CBC) principle. The phase generated by the Dammann grating (DG) beam splitting system is processed and added to the image to be encrypted, and then, the ciphertexts and keys are generated by equal modulus decomposition (EMD). Decryption is to combine the beams through the CDG and collect the combined images in the far field. The proposed encryption scheme is flexible and thus extendable. CDG structure parameters, such as one period length of CDG, can be used as encryption key for the increase of the complexity. The Fresnel diffraction distance can also be used as an encryption key. The power of the combined beam is stronger than that of the single beam system, which is convenient for long-distance transmission and also easy to detect. Simulation results show that the proposed method is effective and efficient for asymmetric multiple-image encryption. Sensitivity analysis of CDG alignment has also been performed showing the robustness of the system. The influence of occlusion attack and noise attack on decryption are also discussed, which proves the stability of the system.

Published: October 2021

Today’s commercially-off-the-shelf (COST) wearable devices can unobtrusively capture several important parameters that may be used to measure the indoor comfort of building occupants, including ambient air temperature, relative humidity, skin temperature, perspiration rate, and heart rate. These data could be used not only for improving personal wellbeing, but for adjusting a better indoor environment condition. In this study, we have focused specifically on the sleeping phase. The main purpose of this work was to use the data from wearable devices and smart meters to improve the sleep quality of residents living at KTH Live-in-Lab. The wearable device we used was the OURA ring which specializes in sleep monitoring. In general, the data quality showed good potential for the modelling phase. For the modelling phase, we had to make some choices, such as the programming language and the AI algorithm, that was the best fit for our project. First, it aims to make personal physiological data related studies more transparent. Secondly, the tenants will have a better sleep quality in their everyday life if they have an accurate prediction of the sleeping scores and ability to adjust the built environment. Additionally, using knowledge about end users can help the building owners to design better building systems and services related to the end-user’s wellbeing.

Phenotypic heterogeneity and molecular diversity make diffuse large B-cell lymphoma (DLBCL) a challenging disease. We recently illustrated that amoeboid movement plays an indispensable role in DLBCL dissemination and inadvertently identified that the inhibitor of bromodomain and extra-terminal (BET) proteins JQ1 could repress DLBCL migration. To explore further, we dissected the impacts of BET inhibition in DLBCL. We found that JQ1 abrogated amoeboid movement of DLBCL cells through both restraining RAS signaling and suppressing MYC-mediated RhoA activity. We also demonstrated that BET inhibition resulted in the upregulation of a GTPase regulatory protein, the IQ motif containing GTPase activating protein 3 (IQGAP3). IQGAP3 similarly exhibited an inhibitory effect on RAS activity in DLBCL cells. Through barcoded mRNA/protein profiling in clinical samples, we identified a specific subgroup of DLBCL tumors with enhanced phosphatidylinositol-3-kinase (PI3K) activity, which led to an inferior survival in these patients. Strikingly, a lower IQGAP3 expression level further portended those with PI3K-activated DLBCL a very dismal outcome. The inhibition of BET and PI3K signaling activity led to effective suppression of DLBCL dissemination in vivo. Our study provides an important insight into the ongoing efforts of targeting BET proteins as a therapeutic approach for DLBCL.
Activity of Cerebellar Nuclei Neurons Correlates with ZebrinII Identity of Their Purkinje Cell Afferents

Published: October 2021

Purkinje cells (PCs) in the cerebellar cortex can be divided into at least two main subpopulations: one subpopulation that prominently expresses ZebrinII (Z+), and shows a relatively low simple spike firing rate, and another that hardly expresses ZebrinII (Z–) and shows higher baseline firing rates. Likewise, the complex spike responses of PCs, which are evoked by climbing fiber inputs and thus reflect the activity of the inferior olive (IO), show the same dichotomy. However, it is not known whether the target neurons of PCs in the cerebellar nuclei (CN) maintain this bimodal distribution. Electrophysiological recordings in awake adult mice show that the rate of action potential firing of CN neurons that receive input from Z+ PCs was consistently lower than that of CN neurons innervated by Z– PCs. Similar in vivo recordings in juvenile and adolescent mice indicated that the firing frequency of CN neurons correlates to the ZebrinII identity of the PC afferents in adult, but not postnatal stages. Finally, the spontaneous action potential firing pattern of adult CN neurons recorded in vitro revealed no significant differences in intrinsic pacemaking activity between ZebrinII identities. Our findings indicate that all three main components of the olivocerebellar loop, i.e., PCs, IO neurons and CN neurons, operate at a higher rate in the Z– modules.
Design of a Neural Super-Twisting Controller to Emulate a Flywheel Energy Storage System
Authors: Magallón Daniel A. , Castañeda Carlos E. , Jurado Francisco , Morfin Onofre A.
Published: October 2021

In this work, a neural super-twisting algorithm is applied to the design of a controller for a flywheel energy storage system (FESS) emulator. Emulation of the FESS is achieved through driving a Permanent Magnet Synchronous Machine (PMSM) coupled to a shaft to shaft DC-motor. The emulation of the FESS is carried out by controlling the velocity of the PMSM in the energy storage stag and then by controlling the DC-motor velocity in the energy feedback stage, where the plant’s states of both electrical machines are identified via a neural network. For the neural identification, a Recurrent Wavelet First-Order Neural Network (RWFONN) is proposed. For the design of the velocity controller, a super-twisting algorithm is applied by using a sliding surface as the argument; the latter is designed based on the states of the RWFONN, in combination with the block control linearization technique to the control of the angular velocity from both machines in their respective operation stage. The RWFONN is trained online using the filtered error algorithm. Closed-loop stability analysis is included when assuming boundedness of the synaptic weights. The results obtained from Matlab/Simulink validate the performance of the proposal in the control of an FESS.

Published: October 2021

In order to investigate the cutting mechanical characteristics of Caragana korshinskii (C.k.) branches and explore the optimal combination of cutting parameters to support the subsequent equipment development, this paper explores the relationship between branch diameter D, average cutting speed v, wedge angle β, slip cutting angle α, cutting height h, cutting gap t, moisture content M and peak cutting force by using a homemade swing-cut branch cutting test bench with peak cutting force of branches as the target value under unsupported and supported cutting methods, respectively, through single-factor tests. Based on the single-factor test, v, β, α and t were selected as the test factors, and a multi-factor test was conducted with the peak cutting force as the target. Test result: The best combination of unsupported cutting in the range of multi-factor test is v for 3.315 m·s−1, β for 20°, α for 20°, when the peak cutting force is 95.690 N. Supported cutting multi-factor test range to get the best combination of v for 3.36 m·s−1, β for 20°, α for 20°, t for 1.38 mm, when the peak cutting force is 53.082 N. The errors of the predicted peak cutting force and the measured peak cutting force of the obtained model were 1.3% and 3.9%, respectively, which prove that the cutting parameters were optimized reliably. This research can provide a theoretical basis for subsequent development the C.k. harvesting equipment.
Mobile App Start-Up Prediction Based on Federated Learning and Attributed Heterogeneous Network Embedding
Authors: Li Shaoyong , Lv Liang , Li Xiaoya , Ding Zhaoyun
Published: October 2021

At present, most mobile App start-up prediction algorithms are only trained and predicted based on single-user data. They cannot integrate the data of all users to mine the correlation between users, and cannot alleviate the cold start problem of new users or newly installed Apps. There are some existing works related to mobile App start-up prediction using multi-user data, which require the integration of multi-party data. In this case, a typical solution is distributed learning of centralized computing. However, this solution can easily lead to the leakage of user privacy data. In this paper, we propose a mobile App start-up prediction method based on federated learning and attributed heterogeneous network embedding, which alleviates the cold start problem of new users or new Apps while guaranteeing users’ privacy.

Published: October 2021

The results of parasitological studies of soil samples taken in the Astrakhan region were analyzed. A total of 4146 soil samples were examined in 2016–2020. Among the positive findings, helminths predominated — 6.5 % (270 samples). The proportion of protozoa among all positive findings in the soil was 0.02 % (1 sample). The largest number of positive findings was recorded in 2016–33.6 % (91 samples) of all positive findings during the analyzed period. Almost 1.3 times less positive findings in the soil were noted in 2018–25.5 % (69 samples) of all positive findings for the analyzed period. In total, 21.8 % (904 samples) of the soil were examined in this year, of which 7.6 % (69 samples) were unsatisfactory. In 2019, the number of positive findings in the studied soil samples was 17.7 % (48 samples) of all positive soil findings in 2016–2020. The number of soil samples studied in 2017 was 18.9 % (783 samples). The lowest number of positive findings — 7.7 % (21 samples) and the studied soil samples — 12.7 % (523 samples) was revealed in 2020. Contamination of the soil with toxocara eggs and strongylid larvae indicates contamination of these objects with the feces of invasive animals (the role of stray animals (dogs) in soil contamination is not excluded).The contamination of the soil with eggs of ascariids, opisthorchis, onkospheres of teniids and cysts of amoebas, suggests that these objects are contaminated with sewage from accidents.

Health risk assessment in the general population in different climate zones of the Krasnoyarsk Territory by the equivalent effective temperature (EET). The average monthly EET according to Missenard was calculated, their dynamics and health risk were assessed within two periods of determining climate norms for the last 10 years of each period (1961–1990 and 1991–2020). Within the period of 1991–2020 compared with the previous period in the subarctic climate in the summer months, EET had positive values (in opposition of 2 months in 1961–1990), increased in April by 7.87 °С (p = 0.0004), in June by 5.56 °С (p = 0.019) and October by 3.2 °С (p = 0.038); in continental climate zone — in April at 5.23 °С (p = 0.0001), in June at 3.88 °С (p = 0.0009) and in August at 1.32 °С (p = 0.023). Living conditions of the population have become more favorable, the nature of the health risk has changed. In the subarctic climate, the changes in uncomfortable conditions occurred according to the criteria of «frostbite threat» — «cold» (5 months against 6 months in the first period), «cool» — «moderately cool» (2 months against 3 months), «comfort, moderately warm. «In the continental climate zone, the changes were noted according to the criteria of «moderately warm» — «very cool» (7 months against 5 months). In both climate zones, positive changes have caused a decrease in health risk according to two criteria («the threat of frostbite»; «very cold»); there was a shift from the risk assessed as «cold»towards «comfort, moderately warm».
Aposterior assessment of occupational pathology risks in copper-nickel miners
Authors: Syurin Sergey Alekseevich
Published: October 2021

Occupational morbidity indicators in the mining industry rank first among all types of economic activity in Russia. The aim of the study was to assess the risks of occupational pathology a posteriori in miners carrying out underground mining of copper-nickel ore in the Kola Arctic. We studied the data of periodic medical examinations and social and hygienic monitoring «Working conditions and occupational morbidity of the population of the Murmansk region.» In 2007, according to the results of medical examinations, 5,007 chronic diseases were identified in 2,042 miners, of which the most common were diseases of the musculoskeletal system (27.7 %) and eye (16.9 %). In 2008–2018, 166 (8.1 %) miners were first diagnosed with 303 occupational diseases, mainly due to increased labor severity (51.5 %) caused by imperfect technological processes (77.6 %). The highest risk of developing occupational diseases was noted among the operators of drilling and tunneling rigs, which significantly exceeded the rates among miners of all other specialties. During labor activity, diseases of the musculoskeletal system most often acquired occupational etiology (41.7 % of all cases). In the structure of nosological forms of occupational diseases, the first places were occupied by vibration disease (21.1 %), radiculopathy (18.5 %) and sensorineural hearing loss (17.5 %). The largest number of cases of occupational diseases per year per 10,000 workers was observed among drillers (540.5 cases) and crushers (441.6 cases), and the smallest — among locksmiths (18.5 cases) and engineering and technical workers (15.5 cases). At present, the modernization of ore mining processes and personal protective equipment, as well as the system of medical measures, do not provide solutions to the problems of preserving the health of the copper-nickel miners of the Kola Polar region.

Published: October 2021

The article justifies the need to study the relationship between wage growth and productivity in agriculture. Particular attention is paid to the experience of individual subjects of the Russian Federation, on the territory of which there are agricultural organizations that fulfill the principle of dependence of wages on the number and quality of goods. It was concluded that at present, with an increase in wages, productivity growth is lagging behind significantly in groups of regions of the Russian Federation. It was suggested that the productivity and wage growth ratio should be used as a tool in the development and implementation of State programmes for the development and support of the agriculture sector.

Visando tornar mais eficiente o protocolo de produção de mudas dessas espécies por meio da propagação vegetativa, o objetivo deste trabalho foi avaliar o enraizamento de estacas caulinares semilenhosas de C. brevipes e C. tweediei mediante a aplicação de diferentes concentrações de ácido indol butírico (IBA). As quatro concentrações de IBA testadas foram: 0 mg L-1 (controle); 1500 mg L-1; 3000 mg L-1; e 6000 mg L-1. C. brevipes apresentou melhor enraizamento que C. tweediei, com maior porcentagem de estacas enraizadas (95,83%), número e comprimento de raízes, porcentagem de estacas que mantiveram as folhas e que emitiram brotações. A aplicação do ácido indol butírico não afetou a taxa de enraizamento, mas proporcionou o aumento do número de raízes para ambas as espécies. Entretanto, crescentes concentrações de IBA reduziram o comprimento de raízes em C. brevipes. Dessa forma, recomenda-se a utilização de ácido indol butírico na concentração de 1500 mg L-1 na propagação vegetativa de C. brevipes e C. tweediei, visando o melhor desenvolvimento do sistema radicial.

A Amazônia é conhecida mundialmente não apenas por suas riquezas, mas também pela exploração predatória de madeira, que culmina no desmatamento ou degradação da vegetação remanescente. Para tentar reverter esse quadro, a algumas décadas vem sendo feito investimentos em empreendimentos florestais de base comunitária (EFC) como o da Cooperativa Mista da Flona do Tapajós, que é referência nessa modalidade de manejo. Assim como em outros empreendimentos é necessário avaliar as atividades do manejo, para melhora a eficiências e o gerenciamento por parte das empresas. Diante disso, o estudo teve o objetivo avaliar a produtividade da colheita florestal em um EFC na Floresta Nacional do Tapajós, gerando coeficientes de produtividade médios para a atividade de derruba com base em dez anos de colheita. Os dados utilizados foram provenientes d provenientes dos Planos Operacionais Anuais (POA), relatórios pós-colheita, autorizações para exploração (AUTEX), inventários 100% e fichas de controle de colheita das unidades de produção de dez Unidades de Produção Anual (UPAs), manejadas, respectivamente, de 2007 a 2016. Inicialmente a Cooperativa apresentou baixa eficiência, retirando um volume menor que 50% do volume autorizado. A partir da UPA 6 a eficiência passou de uma média de 60% para 82%, obtendo um aumento médio de 22% na eficiência. O EFC teve um aumento de 56% na eficiência da colheita, fator relacionado a melhora da predição do estoque de volume da floresta, capacitação do cooperados e a manutenção das equipes de colheita.

Authors: Sil Kunal
Published: October 2021

Standard Costing is one of the very traditional and yet an important tool in cost accounting. It plays a crucial role in controlling costs of an organization. The purpose of this study is to explore how standard costing could be effectively used in even small scale industries. With the emergence of modern scientific accounting systems, few experts have placed their opinion against the use of standard costing, marking it as obsolete and dysfunctional. But, the outcome of this study have shown that application of standard costing as modern management tools is still very much acceptable and in vogue. The lack of proper knowledge of standard costing is the only perceived hindrances in using and applying the same. Like any evolving field, this has to be applied scientifically to fetch the maximum benefit.

According to research on new vocabulary development by text, frequent experiences with foreign words, as well as the context in which these words appear, facilitate word learning and retention. The aim of this analysis was to see how context levels, word occurrence rates, and the combination of these variables affected the understanding and retention of unfamiliar words. Both zero, reduced, and high contexts were included in the study. The research included 60 Turkish EFL university students, with 20 in each of the three situations. The target words were the same for all learners in each condition. The high informative context was discovered that increasing word occurrences had significant effects on both productive and receptive knowledge of meaning while increasing word occurrences had significant effects on both productive and receptive knowledge of word type. The influence of frequent experiences with new words on vocabulary learning was only seen in the more comprehensive sense. It is realistic to provide learners with new words in high context to trigger vocabulary acquisition and retention.

Authors: Nia Zahra Azari , Valizadeh Mohammadreza
Published: October 2021

This study investigated the immediate and sustained effects of revision-mediated (RICF) and attention-mediated (AICF) indirect coded corrective feedback on the written syntactic accuracy development of 50 upper-intermediate Iranian EFL learners assigned to two RICF and AICF groups. They received eight-session treatments, followed by an immediate posttest and then a delayed posttest after a four-week time interval. The collected written scripts were co-rated for syntactic accuracy by the researcher and her colleague. Descriptive and inferential statistical analyses were conducted with SPSS 21. The Wilcoxon Signed Rank Test and the paired-samples t-tests revealed that each treatment separately (i.e., revision-mediated and attention-mediated CF) had a statistically significant impact on EFL learners’ written syntactic accuracy both in the short and long term. Moreover, the independent samples t-tests indicated no significant difference between the effects of revision-mediated and attention-mediated CF on EFL learners’ written syntactic accuracy both in the short and long term. The paper provides discussion and implications.
