The study unearths constraints experienced by teachers' unions in promoting a peaceful learning environment in selected schools of Lusaka, district, Zambia. A case study design was employed on a target population that comprised participants from primary and secondary schools and teacher unions. Expert purposive sampling technique was applied to sample 28 participants from teacher union officials in Lusaka District. Data generated was through interviews and Document Review which was analyzed using themes. Emergent findings revealed that the teachers’ unions faces a myriad of challenges such as inadequate resources, limited knowledge and skills, inaccessible leadership and inadequate financial support in their quest to contribute to a peaceful school environment. Thus, it is recommended among others that, Unions should consider building capacity on resource mobilization and optimal resource utilization, as well as enhancement of mutual consultations with the Ministry of Education and teachers to discuss matters relating to how they can contribute towards raising the standards of learning environment in schools.

Oral corrective feedback on lexical errors: a systematic review
Authors: Tan Xiaochen , Reynolds Barry Lee , Ha Xuan Van 
Published: November 2022

Abstract
This study adopted a synthetic approach to review empirical studies on oral corrective feedback (OCF) for lexical errors. It examined OCF types, lexical target types, interlocutors’ attention to lexical errors, and OCF effectiveness in promoting vocabulary development. After the application of inclusion and exclusion criteria on studies retrieved from a search of six databases, 31 primary studies were available for coding and analysis. Findings revealed that interlocutors showed a greater preference for recast than prompt and explicit correction. However, recast resulted in the lowest rate of lexical repairs, whereas prompt was found the most effective. Lexical errors received OCF at a higher rate than grammatical errors and phonological errors, indicating that interlocutors paid greater attention to vocabulary problems. OCF was most often provided for the inappropriate choice of lexical items, or inaccurate use of word derivation, involving a wide range of word classes (nouns, verbs, adjectives, and adverbs). Only a few studies looked into OCF targeting a single lexical feature. Findings suggest it may be more effective for teachers to employ prompts to elicit repairs of lexical errors from learners. There is a need for future researchers to conduct empirical OCF studies on a single lexical target.

Published: November 2022

Abstract
Unexplained recurrent spontaneous abortion (URSA) is a major concern in reproductive medicine. Neutrophil cytosolic factor 1 (NCF1) polymorphisms leading to low production of reactive oxygen species (ROS) are strongly associated with autoimmune diseases. We investigated the association of the missense single nucleotide polymorphism (SNP) rs201802880 (NCF1-339) in NCF1 with URSA and explored its function. We performed NCF1-339 SNP genotyping of samples from 152 Chinese patients with URSA and 72 healthy controls using nested PCR and TaqMan assays. ROS production and RELA (NF-κB subunit) expression in the blood of participants with different NCF1-339 genotypes were determined. The frequencies of the wild-type (GG) and mutant (GA) genotypes remarkably differed between the URSA and control groups. The mutant genotype was associated with an increased risk of recurrent abortion. Furthermore, ROS levels in the URSA group with the GG genotype were significantly higher than those in the group with the GA genotype (p < 0.05). RELA expression in URSA patients with the GA genotype was considerably higher than that in control individuals with the GG genotype. These findings indicate that mutations in NCF1 may increase the risk of URSA via the NADP/ROS/NF-κB signaling pathway, which has implications for the diagnosis and treatment of URSA.
Research on prehistoric 凸-shaped house remains on the Loess Plateau
Authors: Wang Tianyi 
Published: November 2022

Abstract
The 凸-shaped house remains first appeared in the Guanzhong Basin during the late Yangshao period and became a popular form of architecture in the Loess Plateau during the Longshan period. The form usually consists of an inner room and a front hall connecting to an entranceway. The emergence of the protruding front hall is closely related to the appearance of late Yangshao cave dwellings, where they serve an important role in maintaining the architectural stability of the dwelling. Across the millennium ranging from the late Yangshao to the late Longshan, this architectural structure gradually transformed from a pragmatic-functional attribute into an important cultural symbol.
Statistical modeling and optimization of the bleachability of regenerated spent bleaching earth using response surface methodology and artificial neural networks with genetic algorithm

Published: November 2022

Abstract
In this study, the statistical modeling and optimization of the regeneration of spent bleaching earth (SBE) for re-use in the bleaching of crude palm oil (CPO) oil was examined. Having a good model will assist with the successful optimal regeneration of SBE and hence minimize the environmental pollution associated with its current disposal method which is based on dumping as landfills. The SBE samples were de-oiled with the Soxhlet extraction method, using n-hexane for 1 h at 60 °C; treated at temperatures ranging from 300–500 °C; at carbonization time between 30 and 45 min; and with hydrochloric acid concentrations between 1 and 2 M, at a constant stirring time of 30 min, respectively. The operating conditions for the experiment were according to the Central Composite Design (CCD) experimental design using the Design Expert software version 13. The modeling and optimization of the SBE regeneration process was carried out with the Response Surface Methodology (RSM) and Artificial Neural Network (ANN) techniques. Five regression models were developed from the RSM approach and the best one selected based on model selection parameters recommended in the literature. Similarly, ten ANN models with the number of neurons in the hidden layer that varied from 2 to 16 were considered and the best one selected using the mean square error (MSE) and correlation coefficients (R) for the training, validation and testing performances. Results showed that the ANN technique led to a model with a better predictive ability than the RSM one. The optimum experimental bleachability of 71.5% for the regenerated de-oiled SBE was obtained at carbonization temperature of 500 °C, hydrochloric acid concentration of 2M and carbonization time of 45min. Using the Genetic Algorithm (GA), the ANN model resulted in an optimum bleachability of 70.87% with corresponding optimum factors at 468.19 °C, 2 M and 45 min, while the RSM approach gave an optimum bleachability of 73.52% at the corresponding factors of 498.99 °C, 1.57 M and 41.14 min for the carbonization temperature, acid concentration and carbonization time, respectively. The optimum experimental bleachability of the regenerated SBE achieved was 12.5% higher than that of virgin bleaching earth (VBE).

Published: November 2022

Abstract
Chromium Cr(VI) is a highly toxic environmental contaminant for any organism, its presence in the environment is mainly due to anthropogenic activities. The use of biotechnology has been implemented for the treatment of effluents contaminated with Cr(VI).Our working group has isolated several fungi and bacteria capable of removing Cr(VI) from the culture medium. Aspergillus niger var tubingensis Ed8 is a strain that can produce metabolites which reduce Cr (VI) to Cr (III). The objective of this work was to determine the effect of sodium salicylate on the growth of this strain and on the Cr(VI) reduction system, as well as to identify the metabolites that are produced from sodium salicylate. Our results show that the Culture medium containing sodium salicylate (20 mM) inhibits strain growth compared to the control condition (0 mM). However, it increases the specific reduction capacity of Cr (VI) red/mg Biomass in order of magnitude. Analysis of the culture medium corresponding to 48 h of incubation shows the presence of catechol and salicylate diminution. In addition, as a product of the enzymatic activity of a cell-free cellular extract, after 24 h of incubation, the consumption of salicylate is detected, as well as the presence of peaks corresponding to resorcinol and catechol. Our results show that it is possible to increase the Cr(VI) reducing capacity of the Ed8 strain, depending on the composition of the culture medium.
On endomorphisms of the direct product of two free groups
Authors: Carvalho André 
Published: November 2022

Abstract
We describe the endomorphisms of the direct product of two free groups of finite rank and obtain conditions for which the subgroup of fixed points is finitely generated, and we do the same for periodic points.
We also describe the automorphisms of such a group and solve the three Whitehead problems for automorphisms, monomorphisms and endomorphisms for groups in this class.
We also obtain conditions for an endomorphism to be uniformly continuous when a suitable metric is considered and study infinite fixed points of the extension to the completion of the group.
Maximum electromagnetic local density of states via material structuring
Authors: Chao Pengning , Kuate Defo Rodrick , Molesky Sean , Rodriguez Alejandro 
Published: November 2022

Abstract
The electromagnetic local density of states (LDOS) is crucial to many aspects of photonics engineering, from enhancing emission of photon sources to radiative heat transfer and photovoltaics. We present a framework for evaluating upper bounds on the LDOS in structured media that can handle arbitrary bandwidths and accounts for critical wave scattering effects. The bounds are solely determined by the bandwidth, material susceptibility, and device footprint, with no assumptions on geometry. We derive an analytical expression for the maximum LDOS consistent with the conservation of energy across the entire design domain, which upon benchmarking with topology-optimized structures is shown to be nearly tight for large devices. Novel scaling laws for maximum LDOS enhancement are found: the bounds saturate to a finite value with increasing susceptibility and scale as the quartic root of the bandwidth for semi-infinite structures made of lossy materials, with direct implications on material selection and design applications.

AbstractIn Coronavirus disease 2019 (COVID-19), it is important to evaluate disease activity and investigate possible biomarkers. Therefore, in this study, we investigated the relationship between disease activity and serum levels of possible immune activation marker neopterin in patients with COVID-19. The study enrolled 45 patients (23 females, 51.1%) treated for COVID-19. The patients were divided into two groups according to their clinical presentation: those who recovered quickly (Group 1) and those who worsened progressively (Group 2). The neopterin and C-reactive protein levels were high in all patients on admission. In Group 1, neopterin concentrations and serum neopterin/creatinine ratios were significantly higher on admission compared to Day 14 of the disease, whereas in Group 2, levels were significantly higher at Day 14 of the disease than on admission. Neopterin levels at admission were significantly higher in Group 1. The serum neopterin concentrations at admission were markedly higher in patients with a derived neutrophil–lymphocyte ratio (dNLR) > 2.8 compared to those with a dNLR ≤ 2.8 (p< 0.05). Serum neopterin levels can be used as a prognostic biomarker in predicting disease activity in COVID-19.

Authors: Haque Arina , Firdausi Muhammad Anwar , Zawawi Muhammad , Maimunah Iffat 
Published: November 2022

PurposeThis study aimed to describe the influence of race, environment, and era in Andalusian society on Ibn Zaidun's hymn (praise) and tahniah (congratulations) poetry using the perspective of Hippolite Adolf Taine. MethodThis study was a qualitative research using a library research design that relied on the hymn and tahniah poetry in Diwan Ibn Zaidun: Rasailuhu, Akhbaruhu, Syi'rul Mikjain written by Kamil Kailani and Abdurrahman. This study analyzed the tradition of praise (madah) and congratulations (tahniah) of the Andalusian community in 19 of Ibn Zaydun's poems communicated with 3 indicators of Taine's theory of social facts, namely race, climate, and time factors. Results/FindingsThis study revealed the influence of the three aspects of Andalusian social facts on Ibn Zaidun's poetry, namely: 1) Ras-Spirit, showing that Andalusian society has the tradition of writing poetry for leaders; 2) Environment-Milieau, that was cool climate surrounded by beautiful green plants have a strong influence on Andalusian Literature, giving rise to many expressions of natural beauty in their poems, especially in praise (madah) and congratulations (tahniah) on Ibn Zaidun's poetry; 3) The Age of Moments privileging Andalusian with many muwashahat, so that the poets paid great attention to rhyme (qafiyah) in their poetry, and the uses of the Andalusian language with Arabic writing became greater in a number of poems. ConclusionAndalusian poetry represented by the poet Ibn Zaydun contains three aspects of Tain social facts. Ibn Zaydun's poetry tradition is influenced by the characteristics of Andalusian society, the climate in the Andalusian city, and the time of writing the poem. The author suggests further studies on the Hypolite Taine social fact theory with its unique scope of social facts. Likewise with Andalusian studies, further studies are urgently needed to find the meaning and social facts behind his classical poems.

Authors: Amsariah Siti 
Published: November 2022

PurposeThis study examined the battle of the arena of power between Islam and communism that occurred in the dark events in Indonesia in 1965 through the Najib al-Kailani novel’ 'Adzra Jakarta. MethodThis qualitative research applied a narrative case study design made uses of Najib al-Kailani novel’ 'Adzra Jakarta as the main unit of analysis. To analyzed the data, the study used Pierre Bordieu’s concept of power relations to dismantle the arena fight between Islam and communism in Indonesian history through the capital ownership of figures. Results/FindingsThe results showed a lame power relationship between Islam and communists. Islam in 'Adzra Jakarta is described as inferior because it has only two capitals, while communist ideology holds symbolic capital which includes the other three capitals; Cultural, social and economic capital. However, if you look further at the defeat of Az Zaim by the main character, Fatimah, and his death at the end of the story are symbols of the text's partiality to Islamic ideology. ConclusionThe study concluded that the novel 'Adzra Jakarta reaffirms the perception of the latent danger of the communist ideology constructed by the Indonesian government. Through the main female character, the novel also supports women movement emerged in Egypt.
