Undergraduate Students' Attitudes and Mathematical Reasoning During the Pandemic: The Mediating Role of Metacognitive Awareness

<p style="text-align:justify">During the Covid-19 pandemic, this study investigated the role of metacognitive awareness as a mediator in the correlation between attitude and mathematical reasoning among undergraduates who are first year university students. These studies distribute mathematical reasoning assessments, metacognitive awareness questionnaires, and attitude surveys as research data. One hundred eighty-four undergraduate students from one public institution in Malaysia's Klang Valley area participated in the research. The impact of metacognitive awareness on attitude and mathematical reasoning was studied using Version 25 of the Statistical Packages for the Social Sciences. The findings indicated that undergraduate mathematics and science education students excelled in non-mathematics and science education students in mathematical reasoning capacity. According to the findings, undergraduate mathematics and science education students had good metacognitive understanding and used more approaches in mathematical reasoning assessment. Further study implies that more research should be conducted to assess different demographics, such as institute training teachers' metacognitive awareness and attitude towards mathematical reasoning.</p>

GPT-3.5, GPT-4, or BARD? Evaluating LLMs reasoning ability in zero-shot setting and performance boosting through prompts

Large Language Models (LLMs) have exhibited remarkable performance on various Natural Language Processing (NLP) tasks. However, there is a current hot debate regarding their reasoning capacity. In this paper, we examine the performance of GPT-3.5, GPT-4, and BARD models, by performing a thorough technical evaluation on different reasoning tasks across eleven distinct datasets. Our paper provides empirical evidence showcasing the superior performance of ChatGPT-4 in comparison to both ChatGPT-3.5 and BARD in zero-shot setting throughout almost all evaluated tasks. While the superiority of GPT-4 compared to GPT-3.5 might be explained by its larger size and NLP efficiency, this was not evident for BARD. We also demonstrate that the three models show limited proficiency in Inductive, Mathematical, and Multi-hop Reasoning Tasks. To bolster our findings, we present a detailed and comprehensive analysis of the results from these three models. Furthermore, we propose a set of engineered prompts that enhances the zero-shot setting performance of all three models.

TEACHING MATHEMATICS IN BASIC EDUCATION THROUGH PROBLEM SOLVING

Even today, since the first school years, most of the time in Mathematics classes, it is observed that students learn to do math (algorithms), with predetermined rules and steps, presented on the blackboard and in textbooks, at which they have to follow without, however, previously reasoning why they are doing that, or even without having the possibility of developing their own method to solve mathematical problems. This mechanization of the teaching-learning process of mathematical concepts causes students to lack understanding and interest in the subject. On the other hand, when using the resolution of challenging problem situations, applying examples from the school context, it helps the development of students’ autonomous reasoning. In this context, the present study will focus on the importance of solving problem situations in teaching Mathematics in Basic Education, using bibliographic data as a research method. Furthermore, the main objective of the research is to discuss the importance of solving problem situations in teaching Mathematics in Basic Education. Furthermore, it is worth highlighting that research highlights the role of the teacher as a stimulator and mediator of the hypotheses raised by students, enabling them to develop logical reasoning capacity, understanding the importance of mathematical concepts for their day-to-day lives.

The Effect of Surface Treatment/Polymer Type on Formation of 3D-Boron Nitride Foams

In this study, the use of boron nitride (BN) foam composites as adsorbents in wastewater treatment using polyvinyl alcohol (PVA), polyvinyl butyral (PVB) and polyester (PE) polymers has been investigated. BN powder has been functionalized by Hummer’s and sodium hydroxide (NaOH) methods to facilitate BN binding with the polymer. Fourier Transform Infrared (FT-IR) results show that hydroxyl (-OH) groups are effectively bounded to the BN structure. Scanning Electron Microscope (SEM) observation demonstrated the 3D interconnected porous structure of the obtained BN foams using different polymers. It is observed that BN and polymer interaction is better in foams formed with PVA and PVB compared to PE polymers. PVA and PVB structure shows a bridge property to link the layers so that a porous network structure is formed. It has been determined that the foam composite modified with Hummer’s method and using PVB as a polymer (h-BN-PVB-H) reaches an adsorption capacity of 8.843 mg/g in 44 hours and provides approximately 18% Crystal Violet (CV) dye removal. h-BN-PVB-H foam composite removes approximately 26% of Reactive Blue 49 (RB 49) dye with an adsorption capacity of 12.313 mg/g in the first 10 minutes. The 3D BN/Polymer foams showed reasonable absorption capacities for olive oil, cyclohexane and toluene from 200-980 wt% relative to the foam’s dry weight. It shows that the produced composite foams can absorb approximately 2-10 times their own weight.

Examination of Human Spatial Reasoning Capability and Simulated Autonomous Rendezvous and Docking Monitoring Performance

Autonomous rendezvous and docking (ARD) maneuvers are challenging tasks that require collaboration between a human and a spacecraft to be successful. As automation becomes more integrated into ARD systems, it is important to consider when and why a human may take control. Intrinsic human characteristics can influence these decisions. We consider how human spatial orientation capacity affects participants when monitoring a simulated ARD maneuver and initiating takeover when the system is perceived to be failing. Participants’ spatial reasoning capability was assessed and compared to performance in the monitoring task and perceived mental workload. While participants showed high rates of success in the task, they showed a wide range in spatial reasoning capacity and perceived mental demand. Spatial reasoning capacity did not indicate participants’ mental workload, which has implications for the human as the supervisor. These results inform future work on augmentative displays that may incorporate exocentric and egocentric views.

Lessons Using an Electrochemical Method to Produce Lithium Manganese Oxide Cathodes for Lithium-Ion Batteries

Lithium manganese oxide (LMO) has been a well-studied Li-ion battery cathode material for for many years. It offers high thermal stability for high-temperature battery applications and a prolonged cycle life compared to other materials. LMO also has an acceptably high energy density from a naturally abundant, inexpensive, and environmentally benign material, i.e. manganese (Mn). The cathodes for LIBs are conventionally synthesized via solid-state reaction techniques, which require harsh and complex conditions including high temperature (> 700oC) and high pressure. The resulting powders are incorporated into a slurry that is cast onto a current collector using a binder, additives, and solvent. Though this results in high-performing electrodes, it also usually increases the production cost. Another approach that is gaining traction to make LMOs is electrodeposition. Electrodeposition can allow for the direct synthesis of the active material on the current collector without using any binder or additives. Using electrodeposition not only could eliminate the mass and volume of inactive material but also reduce the cost of electrode fabrication. It also can facilitate recycling by depositing the active material from lower purity, material-digested streams.A few reports in the literature have discussed the electrochemical preparation of LMO cathode from the following steps: electrodeposition of manganese oxide (s) (MnxOy) onto a substrate followed by chemical lithiation and heat treatment of MnxOy [1,2]. Although a few reports showed the active materials with reasonable capacity, it is presently unknown what LiMnxOy phase or phases are active and which MnxOy is responsible. However, without sufficient physicochemical investigation, multiple works have postulated that the LMO is created from crystalline MnO2 or Mn3O4. It is also not known what the typical active phase yield is or what physical structures or conditions are responsible for increased capacity. If electrodeposition-to-LMO is to become a viable commercial pathway, a rational understanding of the solid-state chemistry for the LMO formation is needed.This talk will discuss the deposition and lithiation of multiple manganese oxide phases – linking the chemistry and morphology of the surface features to their charge/discharge properties. It will be shown that traditional crystalline phases are not responsible for the formation of LMOs. It will also be shown that the LMOs do not fully delithiate during charging. Lastly, the precise morphology of the active phase – separated out through new processing approaches – will be identified. The composition, structure, and crystallinity of the Mn oxides and LMOs were characterized by X-ray diffraction, scanning electron microscopy, and energy-dispersive X-ray spectroscopy. The resulting LMO electrodes were incorporated into coin cells, cycled – achieving a capacity of 261 mAh g-1, and post-characterized.References J. Rana, M. Stan, R. Kloepsch, J. Li, G. Schumacher, E.

Unlocking Everyday Wisdom: Enhancing Machine Comprehension with Script Knowledge Integration

Harnessing commonsense knowledge poses a significant challenge for machine comprehension systems. This paper primarily focuses on incorporating a specific subset of commonsense knowledge, namely, script knowledge. Script knowledge is about sequences of actions that are typically performed by individuals in everyday life. Our experiments were centered around the MCScript dataset, which was the basis of the SemEval-2018 Task 11: Machine Comprehension using Commonsense Knowledge. As a baseline, we utilized our Three-Way Attentive Networks (TriANs) framework to model the interactions among passages, questions, and answers. Building upon the TriAN, we proposed to: (1) integrate a pre-trained language model to capture script knowledge; (2) introduce multi-layer attention to facilitate multi-hop reasoning; and (3) incorporate positional embeddings to enhance the model’s capacity for event-ordering reasoning. In this paper, we present our proposed methods and prove their efficacy in improving script knowledge integration and reasoning.

Informatics in brazilian basic education: a bibliographic review of the literature on the subject

The 21st century is a milestone for information technology; smartphones, tablets, computers, among other devices are part of each individual's daily life, whether as a leisure tool, in their personal life, or professionally, as a work tool, making technology one of the most comprehensive and employment fields. Thus, it is important that educational institutions are aware of advances in information technology, seeking the development of teachers and students. The purpose of this work is to understand how information technology occurs in Brazilian basic education. For this, a bibliographic review of the literature was performed, focusing on three aspects: 1) information technology in basic education and its history; 2) implementation and lack of computing education in Brazilian basic education; 3) consequences of this lack of computing education; and 4) the profile of a teacher with qualities for teaching information technology in the basic education network. Among the discussions, it was identified that, in addition to investing in the consolidation of computer labs, it is necessary to invest in teacher training; that it is necessary to reformulate the curriculum and search for new methodological models; that information technology in education stimulates creativity, logical reasoning, collaboration, and research capacity; that schools find difficulties on the use of computing, and that knowledge of computing is necessary for new professional practices.

Ecological Fall Prediction Sensitivity, Specificity, and Accuracy in Patients with Mild Cognitive Impairment at a High Risk of Falls.

While falls among patients with mild cognitive impairment (MCI) have been closely associated with an increased postural sway during ecological activities of daily living, there is a dearth of postural sway detection (PSD) research in ecological environments. The present study aimed to investigate the fall sensitivity, specificity, and accuracy of our PSD system. Forty healthy young and older adults with MCI at a high risk of falls underwent the sensitivity, specificity, and accuracy tests for PSD by simultaneously recording the Berg Balance Scale and Timed Up and Go in ecological environments, and the data were analyzed using the receiver operating characteristic curve and area under the curve. The fall prediction sensitivity ranged from 0.82 to 0.99, specificity ranged from 0.69 to 0.90, and accuracy ranged from 0.53 to 0.81. The PSD system's fall prediction sensitivity, specificity, and accuracy data suggest a reasonable discriminative capacity for distinguishing between fallers and non-fallers as well as predicting falls in older adults with MCI in ecological testing environments.

Diagnostic performance of SARC-F and SARC-CalF in screening for sarcopenia in older adults in Northern Brazil

To compare the performance of SARC-F and SARC-CalF as screening tools for sarcopenia. Cross-sectional study with a convenience sample of 312 community-dwelling older people. Sarcopenia was defined as low handgrip strength (HGS) or low gait speed (GS ≤ 0.8 m/s). HGS was measured by dynamometry and GS by the 4-m walking speed test. For HGS, six criteria (C) were used to identify sarcopenia in men/women: CI: < 27 kg/16 kg; CII: < 35.5 kg/20.0 kg; CIII: grip over body mass index < 1.05/< 0.79; CIV: grip strength over total body fat < 1.66/< 0.65; CV: grip over bodyweight < 0.45/< 0.34; CVI: < 27 kg/16 kg and low skeletal muscle mass index (SMMI); CI and CVI defined according to the European Working Group on sarcopenia in older people and the rest according to the sarcopenia definition and outcomes Consortium. For sarcopenia screening, the SARC-F (≥ 4 points) and the SARC-CalF (≥ 11 points) were used. The kappa analysis revealed no agreement between the SARC-F and the various criteria for the identification of sarcopenia in men. The same lack of agreement was observed in women with some exceptions: CI = 0.161 ± 0.074, p = 0.020; GS = 0.209 ± 0.076, p = 0.003. Concerning the Cohen’s kappa between the SARC-Calf and the reference criteria of sarcopenia, the following coefficients were observed as significant for women: CI = 0.201 ± 0.069, p = 0.003; CII = 0.186 ± 0.064, p = 0.005; GS = 0.273 ± 0.068, p = 0.0001; and for men: CII = 0.139 ± 0.053, p = 0.021; GS = 0.223 ± 0.099, p = 0.011. ROC curves revealed the SARC-Calf with acceptable discrimination and reasonable sarcopenia predictive capacity considering a cutoff value of 10.5 in both men (AUC: 67.5%, p = 0.022; Se = 52.9%; Sp = 76.8%) and women (AUC: 72.4%, p < 0.001; Se = 63%; Sp = 68.5%) concerning GS. The SARC-CalF performed better than the SARC-F for screening sarcopenia in the population ≥ 60 years of age in the Amazonas, measured through walking slowness.

Boosting reversible anionic redox reaction with Li/Cu dual honeycomb centers

The anionic redox reaction (ARR) is a promising charge contributor to improve the reversible capacity of layered-oxide cathodes for Na-ion batteries; however, some practical bottlenecks still need to be eliminated, including a low capacity retention, large voltage hysteresis, and low rate capability. Herein, we proposed a high-Na content honeycomb-ordered cathode, P2–Na5/6[Li1/6Cu1/6Mn2/3]O2 (P2-NLCMO), with combined cationic/anionic redox. Neutron powder diffraction and X-ray diffraction of P2-NLCMO suggested P2-type stacking with rarely found P6322 symmetry. In addition, advanced spectroscopy techniques and density functional theory calculations confirmed the synergistic stabilizing relationship between the Li/Cu dual honeycomb centers, achieving fully active Cu3+/Cu2+ redox and stabilized ARR with interactively suppressed local distortion. With a meticulously regulated charge/discharge protocol, both the cycling and rate capability of P2-NLCMO were significantly improved, demonstrating reasonable capacity and eliminating voltage hysteresis. Overall, this work contributes a well-defined layered oxide cathode with combined cationic/anionic redox towards rational designing advanced Na-ion batteries.

LA SPECIALE NATURA DEI SOGNI E I DIRITTI DEGLI ANIMALI NEI &lt;em&gt;TRÄUME&lt;/em&gt; DI JOHANN GOTTLOB KRÜGER (1754)

Without a doubt, the issue of animal rights has now become part of the socio-cultural perspective in a much stronger moral and legal sense than in the past, in the wake of the “animal turn” of the early 90s of the last century. One aspect that has been most debated since ancient times is, however, whether animals have a soul and whether the lack of speech can be considered a symptom of a completely inferior capacity for reasoning. The era of the European Enlightenment certainly showed a peak of interest in this debate, especially on the basis of scientific experiments carried out on animals, but also on the basis of reflections on the natural law of living beings. In Germany, as part of the medical studies in Halle, Johann Gottlob Krüger distinguished himself for having grasped the importance of the considerations - albeit sometimes paradoxical - that had emerged in the context of several interdisciplinary symposiums held in Leipzig at the beginning of the years’ 40 of the eighteenth century on the theme of the soul of animals. The classical philologist Johann Heinrich Winkler had published them later, in 1745, in a volume entitled Philosophische Untersuchungen von dem Seyn und Wesen der Seelen der Thiere […], already preceded by another from 1742, dedicated to a similar topic. The point of interest, however, consists in the particular literary strategy with which Krüger returns these debates of an academic nature, taking advantage of the register of satire to make animals and men and animals of various species interact with each other. In the fictitious dimension of the dream, in which the Hallense physician situates these disputes, it is possible to retrace the various theoretical stages that in the philosophical field accompanied the development of the vexata quaestio relating to the soul of animals, reviewing the positions of Girolamo Rorario (1485-1556), of the surgeon Girolamo Fabrici d’Acquapendente (1533-1619), of Montaigne (1533-1592), of Descartes (1596-1650) and of the iatroteologist Michael Alberti (1682-1757). What matters most, however, are the absurd theoretical justifications that human thought pushes to legitimize its unfair attitude towards the animal world, well highlighted in Krüger’s literary dreams.

Copper Doping of CoSe2 Nanoparticles Encapsulated into Carbon Nanotubes with Enhanced Electron Conductance as Cathode for Rechargeable Magnesium Batteries

AbstractRechargeable magnesium batteries (RMBs) have been considered a promising alternative to lithium‐ion batteries (LIBs) due to the high energy density and abundance of magnesium resources. However, the development of high‐performance cathode materials for magnesium batteries has been a significant challenge. Herein, through comprehensive and simple hydrothermal, selenization and impregnation methods, Cu‐doped CoSe2 nanoparticles encapsulated into carbon nanotubes (Cu‐CoSe2@NC) was fabricated. CoSe2 nanoparticles confined in carbon nanotubes (CNTs) growing in three dimensions on the surface of nanofibers have abundant active sites and high doping degree. Cu doping further improves the electron conductance of the Cu‐CoSe2@NC for RMBs. As cathode, Cu‐CoSe2@NC delivers a reversible capacity of 294 mAh g−1 at 20 mA g−1 and 104 mAg g−1 at 500 mA g−1, which exhibits a reasonable specific capacity and rate capability. The characterization of the Cu‐CoSe2@NC by ex‐situ transmission electron microscopy (TEM) after cycles shows that it can be well adapted to the (de)intercalation of magnesium ions. Density Functional Theory (DFT) calculation shows that CoSe2 band gap decreases obviously after Cu doping, favoring the electron and ion transport. This work provides a reference for the design of cathode materials based on transition metal selenide for RMBs.

Experimentation of Transformative Learning and Realistic Mathematic Education Learning Models on Mathematics Learning Achievement

The research aims to investigate and evaluate the efficacy of different learning models on mathematics learning outcomes, specifically focusing on the students' van Hiele geometric reasoning capacity. The study employed a quasi-experimental design. The practice is carried out in Public Junior High Schools in Sukoharjo Regency, part of the Central Java Province in Indonesia. The utilized learning models were transformative learning, actual mathematics education, and direct instruction. The study encompassed a total of 281 individuals, who were selected from 9 classes across three distinct institutions. Data analysis is conducted with a two-way analysis of variance (ANOVA) approach. The research findings indicate that (1) the learning model has a positive and significant impact on mathematics learning outcomes; (2) the van Hiele level of geometric thinking ability has a positive and significant influence on mathematics learning outcomes; (3) there is a positive and significant interaction between learning models and van Hiele level of geometric thinking ability on mathematics learning outcomes; and (4) among the transformative learning, Real Mathematics Education, and Direct Instruction models, the transformative learning model yields the best mathematics learning outcomes.

In the absence of extensive initial training, cleaner wrasse Labroides dimidiatus fail a transitive inference task.

Transitive inference (TI) is a reasoning capacity that allows individuals to deduce unknown pair relationships from previous knowledge of other pair relationships. Its occurrence in a wide range of animals, including insects, has been linked to their ecological needs. Thus, TI should be absent in species that do not rely on such inferences in their natural lives. We hypothesized that the latter applies to the cleaner wrasse Labroides dimidiatus and tested this with 19 individuals using a five-term series (A > B > C > D > E) experiment. Cleaners first learned to prefer a food-rewarding plate (+) over a non-rewarding plate (-) in four plate pairs that imply a hierarchy from plate A to plate E (A+B-, B+C-, C+D-, D+E-), with the learning order counterbalanced between subjects. We then tested for spontaneous preferences in the unknown pairs BD (transitive inference task) and AE (as a control for anchors), interspersed between trials involving a mix of all known adjacent pairs. The cleaners systematically preferred A over E and showed good performance for A+B- and D+E- trials. Conversely, cleaners did not prefer B over D. These results were unaffected by the reinforcement history, but the order of learning of the different pairs of plates had a main impact on the remembrance of the initial training pairs. Overall, cleaners performed randomly in B+C- and C+D- trials. Thus, a memory constraint may have prevented subjects from applying TI. Indeed, a parallel study on cleaner wrasse provided positive evidence for TI but was achieved following extensive training on the non-adjacent pairs which may have over-ridden the ecological relevance of the task.

Electrochemical analysis on the role of disulfide bonds in polysulfide-co-polyoxide as cathode active binder for enhanced storage capacity of lithium-metal batteries

The present article is aimed at elucidation on the role of disulfide bonds in enhancement of energy storage capacity of lithium metal battery using polysulfide-co-polyoxide as cathode active binder in lithium metal batteries. Upon photocuring via ‘thiol-ene’ reaction, the resulting thioplast-co-trimethylolpropane ethoxylate triacrylate (TMPETA) co-network is flexible containing disulfide and ether oxygen moieties. Ionic conductivity of the polymer electrolyte membrane containing Thioplast-co-TMPETA network/plasticizer/lithium salt reaches the superionic conductor level of 10−3 S cm−1 at room temperature. To further improve the electrochemical performance, Thioplast-co-TMPETA co-networks were used as a binder, in lieu of polyvinylidene fluoride (PVDF), for lithium iron phosphate (LFP) cathode. Of particular interest is the achievement of a high overall specific capacity of ∼265 mAh g−1 initially which stabilizes at ∼185 mAh g−1 after 35 cycles. These values certainly exceeded the theoretical value of 170 mAh g−1 for neat LFP cathode. This capacity enhancement may be attributed to the disulfide bonds of polysulfide constituent undergoing SS bond scission followed by electron acceptor-donor interactions between sulfide radicals and Li cations. Moreover, the polysulfide-co-polyoxide binder also works as a cathode active material with a specific capacity of 122–103 mAh g−1 in the potential range of 1.0–3.0 V showing reasonable capacity retention of ∼85% and Coulombic efficiency of ∼97%.

Advancing critical discourse analysis of Indigenous consultations: Argument Continuity v. epistemic vigilance

ABSTRACT The paper conducts the critical discourse analysis of Indigenous consultation reports with the help of Argument Continuity, a brand-new critical discourse analysis category. Argument Continuity is a set of the same arguments and counterarguments repeatedly produced/reproduced by the institutionally dominant arguer through an adversarial reasoning process to dismiss opposing arguments without reflecting upon their merits. Argument Continuity is contingent upon motivated criticism, a reasoning practice of biased evaluation of opposing arguments. Epistemic vigilance is a polar reasoning practice of unbiased evaluation of opposing arguments that never results in responding to them with Argument Continuity. The paper applies an institutionalist perspective to tracing and explaining the reasoning dynamics of motivated criticism and epistemic vigilance in the distorted (controlled) context of reasoning interactivity between arguers with power asymmetries. Contrasting the Indigenous consultations over the Trans Mountain and Mackenzie Valley pipelines, the paper reveals how the institutional context constraining/advancing the reasoning capacity of Indigenous arguers to resist the controversial project made it easier/harder for the institutionally dominant officials to employ motivated criticism/epistemic vigilance, responding to Indigenous concerns with or without Argument Continuities.

Store or not to store: a comparative study on the physicochemical properties of pumpkin

The nutritional value of postharvest pumpkin is affected by different factors, including storage which can maintain or reduce quality. This study was conducted to determine the influence of storage on the physicochemical properties and antioxidant capacity of pumpkins. Storage of raw pumpkins under room temperature (28 ± 2 °C and 60 ± 5% RH) conditions for 20 days was beneficial without unfavorable effects on the fruit weight, flesh thickness, dry matter (DM), and total soluble solids (TSS). Storage changed the pulp color from yellow-orange to orange. Likewise, the rind became orange with a white substance on the surface from mixed colors of green and yellow. Storage positively increased total sugar contents by 10 folds compared to non-stored raw pumpkins. However, storage adversely affected the total flavonoid contents, which resulted in the content’s decline. Additionally, the antioxidant capacity (2,2-diphenyl-2-picryl-hydrazyl (DPPH) scavenging radical activity and Ferric Reducing Antioxidant Power (FRAP) assays) exhibited lower values in stored pumpkins. In addition, it would hold the fruits for 20 days avoiding surplus supply in the market, sweeter pulps, and reasonable antioxidant capacity, and a suitable mitigation strategy for postharvest loss.

Induction, Deduction, and Visual-Spatial Perception: The Finnegans Wake Intelligence Test

Abstract: Finnegans Wake makes intense demands on its readers’ intellectual energies, and I propose that the text brings our cognitive reasoning capacities to the foreground by putting them to work. In this, the Wake resembles an intelligence test, calling upon abilities of deduction, induction, and visual-spatial perception. Using deduction, readers draw upon existing linguistic paradigms in order to make sense of Joyce’s neologisms, while induction involves identifying patterns created by the text itself. Moreover, “characters” such as HCE are often denoted only by the appearance of these letters, activating pattern-recognition skills. Nevertheless, identifying these references is not the end-point of studying the Wake , since dissecting Joyce’s text into an inventory of allusions would dissolve its artistry. Instead, discerning familiar elements in Joycean innovations is a fluid and ongoing process, where the manifestation of one’s own cognitive processes constitutes an aesthetic effect.

Research on production capacity planning method of open-pit coal mine

Reasonable production capacity is related to the economic benefits of an open-pit coal mine. This study analyzes the relationship between the working face length, the annual advancing speed and the production capacity. It constructs a production capacity function relationship model. Take the Baorixile open-pit coal mine as an example. The remaining unmined parts are divided into four regions, and the range of production capacity in each region is analyzed by the established model and the determined respectively. On this basis, three mining district division plans are proposed. By analyzing and comparing the stripping ratio, mining life of the district, fault influence, difficulty of transition connection in the mining districts, the convenience of transportation system layout and other indexes of each plan, Plan 3 is determined to be the optimal plan. The production capacity planning results of each mining district in this plan are as follows: the production capacity of the 3rd mining district is 30–35 Mt/a; the production capacity of the 4th mining district in Region 1 is 20–31 Mt/a, and the production capacity in Region 2 is 24–33 Mt/a; the production capacity of the 5th mining district is 20–27 Mt/a.
