Like most other states, Missouri uses assessments intended to measure whether students are on a pathway to "college and career readiness." The state longitudinal data system now has the capacity to directly test that claim. We make use of 8th-grade assessment (MAP) scores in Math, Science, and Communication Arts for roughly 260,000 first-time Missouri freshmen who began high school between Fall, 2009 and Fall, 2012. These students were tracked through high school and for five years following on-time high school graduation. We find a strong positive association between MAP performance scores in 8th grade Math, Science, and Communication Arts and post-secondary college attendance and degree completion. This is true overall and for White, Black, and Hispanic students disaggregated by gender. Proficiency on all three exams matters even more. Based on a logistic forecasting model, if all students who scored below Proficient on the 8th-grade MAP raised their scores to Proficient, the number earning post-secondary degrees would increase by roughly 50 percent. Black and Hispanic students earning post-secondary degrees would increase by roughly 150 and 75 percent, respectively. We conclude that 8th-grade MAP proficiency scores are highly informative about whether students are on a pathway to college and career readiness.

The New York State Education Department (NYSED) has a partnership with NWEA for the development of the 2024 Grades 3-8 English Language Arts Tests. Teachers from across the State work with NYSED in a variety of activities to ensure the validity and reliability of the New York State Testing Program (NYSTP). The 2024 Grades 6 and 7 English Language Arts Tests are administered in two sessions on two consecutive school days. Students are asked to demonstrate their knowledge and skills in the areas of reading and writing. Students will have as much time as they need each day to answer the questions in the test sessions within the confines of the regular school day. For Grades 6 and 7, the tests consist of multiple-choice (1-credit) and constructed-response (2- and 4-credit) questions. Each multiple-choice question is followed by four choices, one of which is the correct answer. Students record their multiple-choice responses on a separate answer sheet. For Session 1, students will write their responses to the constructed-response questions in their separate answer booklets. For Session 2, students will write their responses to these questions directly in their test booklets. By following the guidelines in this document, teachers help ensure that the test is valid, reliable, and equitable for all students. A series of instructions helps teachers organize the materials and the testing schedule.

This occasional paper presents national demographic subgroup data for the 1975-2022 Monitoring the Future (MTF) national survey results on 8th, 10th, and 12th graders' use of drugs, alcohol, and tobacco. The study covers all major classes of illicit and licit psychoactive drugs for an array of population subgroups. The 2020 subgroup data presented in this report accompany the "Monitoring the Future National Survey Results on Drug Use: 1975-2022: Overview, Key Findings on Adolescent Drug Use" (ED627365) and the "Monitoring the Future National Survey Results on Drug Use, 1975-2022: Secondary School Students" (ED627366). The trends shown in both tabular and graphic forms in this report cover demographic subgroups based on: (1) Gender; (2) College plans; (3) Region of the country; (4) Population density; (5) Education level of the parents (a proxy for socioeconomic level); and (6) Racial/ethnic identification.

The Federal Bureau of Investigation was the catalyst that established the theme for the Twenty-First Allerton Institute, held at the University of Illinois at Urbana-Champaign's Allerton House, October 29-31, 1989. The FBI's Library Awareness Program, if it had any merit, did raise a significant ethical conflict between the librarian's responsibility to preserve the confidentiality surrounding use of library materials and his or her responsibility as a citizen of the United States. The FBI's activities, along with an apparent increase in interest in ethical matters in society as a whole, suggested "professional ethics" as an appropriate theme for a conference of librarians in 1989., published or submitted for publication

Research reveals better school and student outcomes, especially for teachers and children of color, when a principal of color is at the helm. One way to improve the educational experiences of schoolchildren across the country is to increase their access to leaders of color--and strengthen the caliber of teaching and leading in our nation's schools. Yet, despite the fact that diversity among our nation's students is growing, diversity among teachers, principals, and district leaders continues to lag. This is known as the representation gap. Strategic investments are needed to develop the next generation of school leaders who better reflect the communities they serve. A recent survey of district leaders conducted by New Leaders suggests a disconnect between intention and actions taken to advance diversity. The majority of respondents state that their district is committed to improving the diversity of its leaders, but an almost equal number report that there is no clear leadership path for educators of color within their district. Building a diverse pipeline of school leaders who are well prepared and supported enables districts to retain the kind of talent that ensures all students thrive. This paper examines five actions school districts can take to shape the future of educational leadership in their district.

Microbial contamination causes environmental and costly problems in paper production (gas formation in stored pulp, and biofilm/slime) and waste water systems (biofilm formation causing corrosion of the pipes). Today, chemical-based biocides are used to control these problems. We have developed a biocide substitute consisting of industrial rest products; rye bran or spruce bark. Rye bran is a suitable nutrient for growth of a selected strain of Lactiplantibacillus plantarum. Previous studies have shown that fermented rye bran, as well as spruce bark extracts, contains bioactive metabolites with the power to limit virtually all bacterial growth. These products also contain fibres with potential to be a supplement as raw material in the pulp. Our intention with this study was to investigate the potential of these rest materials as an antibacterial raw material in paper production. We will specifically determine the antibacterial effect on strains isolated from pulp, process water from the paper mill, and waste water pipes. In addition, likewise analyse the antimicrobial activity of single metabolites discovered in the crude extracts. The results so far, show that the products efficiently inhibit growth of the bacterial strains isolated from waste water and the paper mill. The pure metabolites showed also antibacterial properties, but were less potent as compared to the crude products. The Lactiplantiobacillus strain, used to ferment the rye bran in the present study, was resistant to all the tested products. In conclusion, fermented rye bran and spruce bark extracts show properties indicating a potential to be used as a bioactive raw material, limiting the need of adding synthetic biocides in paper production and waste water systems.

Passive indoor moisture control is a meaningful way to reduce HVAC operation and improve building energy efficiency. Metal-organic frameworks (MOFs) have been considered one of the most promising sorbent materials for passive indoor moisture control. However, the powder form of MOF is challenging to use in the built environment. Typical shaping methods like pellets, beads, and coating can lead to problems like partial pore blocking, insufficient mechanical stability, amorphization, and low material utilization. Here, we report a new sustainable MOF paper sheet comprising 25% cellulosic fibers and 75% MOF MIL-100(Fe) powder. The porous polymer matrix provides good support and fixation for MOF particles, so it’s more applicable in the built environment. The crystalline and pore structure characteristics of the MOF in the membrane are well preserved. Hydro characteristic test results show that MIL-100(Fe) paper sheet has high water vapor uptake, S-shape isotherm, mild regeneration condition, and high MBV. Then, a numerical model was developed to calculate the relation between a material’s MBV and its thickness. MIL-100(Fe) paper sheet with the most efficient thickness was applied as wallpaper in a building energy simulation model. The simulation result shows that the MIL-100(Fe) paper sheet is promising for passive indoor moisture control. It can remove about 45%-55% of the latent cooling load in most European climate types.

Introduction: Paper folding and punched hole tests are used to measure spatial abilities in humans. These abilities are relevant since they are associated with success in STEM (Science, Technology, Engineering, and Mathematics). This study addresses the challenge of teaching spatial reasoning skills using an educational videogame, the Paper Folding Reasoning Game. Methods: The Paper Folding Reasoning Game is an interactive game which presents activities intended to help users train and understand how to fold a paper to get a specific shape (Part I) and the consequence of punching a hole on a folded paper (Part II). This educational videogame can automatically generate paper-folding-and-punched-hole questions with varying degrees of difficulty depending on the number of folds and holes made, thus producing additional levels for training due to its embedded reasoning mechanisms (Part III). Results: This manuscript presents the results of analyzing the gameplay data gathered by the Paper Folding Reasoning Game in its three parts. For Parts I and II, the data provided by 225 anonymous unique players are analyzed. For Part III (Mastermode), the data obtained from 894 gameplays by 311 anonymous unique players are analyzed. In our analysis, we found out a significant difference in performance regarding the players who trained (i.e., played Parts I and II) before playing the Mastermode (Part III) vs. the group of players who did not train. We also found a significant difference in players' performance who used the visual help (i.e., re-watch the animated sequence of paper folds) vs. the group of players who did not use it, confirming the effectiveness of the Paper Folding Reasoning Game to train paper-folding-and-punched-hole reasoning skills. Statistically significant gender differences in performance were also found.

The fourth industrial revolution, colloquially referred to as “industry 4.0”, has garnered substantial global attention in recent years. There, Artificial intelligence (AI) driven industrial intelligence has been increasingly deployed in predictive maintenance (PdM), emerging as a vital enabler of smart manufacturing and industry 4.0. Since in recent years the number of articles focusing on Artificial Intelligence (AI) in PdM is high a review on the available literature reviews in this domain would be useful for the future researchers who would like to advance the research in this area and also for the persons who would like to apply PdM in their application domains. Therefore, this study identifies the AI revolution in PdM and focuses on the next stages available in the literature reviews in this area by quality assessment of secondary study. A well-known structured review approach (Systematic Literature Review, or SLR) was employed to perform this tertiary study. In addition, the Scale for the Assessment of Narrative Review Articles (SANRA) approach for evaluating the quality of review papers has been employed to support a few of the research questions. Here, This tertiary study scrutinizes four crucial aspects of secondary articles: (1) their specific research domains, (2) the annual trends in the quantity, variety, and quality (3) a footsteps of top researchers, and (4) the research constraints that review articles face during the time frame of 2015 to 2022. The results show that the majority of the application areas are applied to the manufacturing industry. It also leads to the identification of the revolution of AI in PdM as well. Our final findings indicate that Dr. Cheng et al.’s (2022) review has emerged as the predominant source of information in this field. As newcomers or industrial practitioners, we can benefit greatly from following his insights. The final outcome is that there is a lack of progress in SLR formulation and in adding explainable or inte

The materials to produce concrete blocks (sand, gravel, and cement) are limited resources that are becoming scarce over time due to their increasing demand in construction. On the other hand, the waste of glass and paper is progressively increasing without being fully utilized through recycling. Therefore, the objective of this scientific research is to evaluate the influence on the mechanical properties of masonry concrete blocks made with recycled glass and paper particles. Likewise, the sample was non-probabilistically selected for convenience, consisting of 192 concrete blocks manufactured with additions of 3% (2% glass particles and 1% recycled paper), 6% (4% glass particles and 2% recycled paper), and 9% (6% glass particles and 3% recycled paper), as well as concrete blocks manufactured without additions. According to the results obtained, at 3%, 6%, and 9% addition of glass and paper particles, the absorption decreased by 4.94%, 3.398%, and 3.52% respectively. However, the warping increased between 1.7mm and 1.8mm, while the compressive strength (f'c) increased to 75kg/cm2, 82kg/cm2, and 77kg/cm2, respectively. Similarly, the axial compressive strength (f'm) increased to 91.22kg/cm2, 94.45kg/cm2, and 92.80kg/cm2, and the diagonal compressive strength (V'm) increased by 8.90kg/cm2, 9.70kg/cm2, and 9.70kg/cm2. Nevertheless, the manufacturing cost of masonry units showed a progressive reduction with the amount of glass + paper addition, amounting to 0.57 USD, 0.55 USD, and 0.53 USD. It was also determined that the optimal addition of these materials in the concrete mix in terms of cost and strength is 9% (glass + paper), resulting in compressive strengths of 77kg/cm2, 92.8kg/cm2, and 9.70kg/cm2, with a cost of 0.53 USD per unit. In conclusion, it can be affirmed that adding glass and recycled paper particles in the production of concrete blocks for use in load-bearing masonry walls positively influences the physical and mechanical properties of the blocks.

The electrification and digitalization of our society has propelled the demand for energy storage solutions. High-end technologies have been developed to satisfy the requirements of demanding applications, such as electromobility and portable consumer electronics, which also increasingly find markets for less demanding applications. These markets include grid and domestic energy storage, as well as Internet of Things (IoT). However, using high-end technologies for low-end applications is a waste of resources that puts unnecessary stress on the supply lines. Thus, more low-cost cost and environmentally friendly alternative technologies are sought, among which renewable biobased materials derived from agriculture and forestry play a prominent role. The dominant chemical constituents in plants, cellulose and lignin, exhibit some intriguing electrochemical and colloidal properties. Cellulose has been found to efficiently stabilize various electronic materials, whereas lignin can be used as an electronic material itself. Lignocellulosic materials also open for papermaking as an alternative manufacturing approach. Taking the step to using papermaking methods is, however, a bit far from the technology readiness level, as the vast majority of the research on paper electrodes is based on nanocellulose. The material properties of such nanopapers are indeed extraordinary, but the lack of large-scale production methods for nanopapers is a serious challenge. To circumvent this obstacle and find a shortcut to the realization of paper electrodes, this thesis has turned to conventional papermaking techniques. Fibres are essentially different to nanofibrils by their difference in size, and the papermaking process requires careful composition of the formulations. Thus, as the research on nanopaper electrodes cannot be directly translated into conventional papermaking techniques, this calls for separate studies on fibre-based systems. This thesis is based on four separate works carrie

Due to its unique material properties, paper offers many practical advantages as a viable platform for sensing devices. In view of paper-based microfluidic biosensing applications, the covalent immobilization of enzymes with preserved functional activity is highly desirable and ultimately challenging. In the present manuscript, we report an efficient approach to achieving the covalent attachment of certain enzymes on paper fibers via a surface-bound network of hydrophilic polymers bearing protein-modifiable sites. This tailor-made macromolecular system consisting of polar, highly swellable copolymers is anchored to the paper exterior upon light-induced crosslinking of engineered benzophenone motifs. On the other hand, this framework contains active esters that can be efficiently modified by the nucleophiles of biomolecules. This strategy allowed the covalent immobilization of glucose oxidase and horseradish peroxidase onto cotton linters without sacrificing their bioactivities and performance upon surface binding. As a proof-of-concept application, a microfluidic chromatic paper-based glucose sensor was developed and achieved successful glucose detection in a simple yet efficient cascade reaction.

The sharing and documentation of cardiovascular research data are essential for efficient use and reuse of data, thereby aiding scientific transparency, accelerating the progress of cardiovascular research and healthcare, and contributing to the reproducibility of research results. However, challenges remain. This position paper, written on behalf of and approved by the German Cardiac Society and German Centre for Cardiovascular Research, summarizes our current understanding of the challenges in cardiovascular research data management (RDM). These challenges include lack of time, awareness, incentives, and funding for implementing effective RDM; lack of standardization in RDM processes; a need to better identify meaningful and actionable data among the increasing volume and complexity of data being acquired; and a lack of understanding of the legal aspects of data sharing. While several tools exist to increase the degree to which data are findable, accessible, interoperable, and reusable (FAIR), more work is needed to lower the threshold for effective RDM not just in cardiovascular research but in all biomedical research, with data sharing and reuse being factored in at every stage of the scientific process. A culture of open science with FAIR research data should be fostered through education and training of early-career and established research professionals. Ultimately, FAIR RDM requires permanent, long-term effort at all levels. If outcomes can be shown to be superior and to promote better (and better value) science, modern RDM will make a positive difference to cardiovascular science and practice. The full position paper is available in the supplementary materials.

Paper documents, where digital signatures are not directly applicable, are still widely utilized due to usability and legal reasons. We propose a novel approach to authenticating paper documents by taking short videos of them with smartphones. Our solution combines cryptographic and image comparison techniques to detect and highlight semantic-changing attacks on rich documents, containing text and graphics. We provide geometrical arguments for the security of our novel comparison algorithm, and prove that its combination with a cryptographic protocol is secure against strong adversaries capable of compromising different system components. We also measure its accuracy on a set of 128 videos of paper documents and a set of 960 synthetically generated warped documents, half containing subtle forgeries. Our algorithm finds all forgeries accurately with no false positives. The highlighted regions are large enough to be visible to users, but small enough to precisely locate forgeries.

Assessments of greenhouse gas (GHG) emissions in managed areas are facing various challenges. A non-flow-through, non-steady-state (NFT-NSS) chamber coupled to a frame permanently inserted into the landfilled substrates is a standard method for quantifying GHG emissions in managed areas, such as pulp and paper mill sludge (PPMS) landfill sites. Frequent measurements are needed to minimize uncertainties on GHG emission factors at the landfill site scale. However, maintaining a frame inserted into the substrates for a long time period is often impossible due to landfilling management operations. Therefore, GHG measurements using NFT-NSS chambers placed directly on substrates’ surface could be an interesting option. Our objectives were to determine the relationships between CO2, CH4, and N2O fluxes measured with (F + ) and without (F-) a frame inserted in the substrates’ surface and to develop correction factors for fluxes measured without a frame. Measurements were made at different PPMS landfill sites in the province of Québec, Canada. Stronger GHG flux relationships were observed at the provincial (across sites) than the specific site scale: the variance in GHG fluxes from F- chambers explained up to 80 % of variance in fluxes from F + chambers. The measured CO2, CH4, and N2O fluxes in F- chambers were on average 53, 78, and 63 % lower, respectively, than those estimated by the models at provincial scale. The correction factors developed with this approach could greatly extend the number of sites where in situ GHG measurements can be done and would help refining GHG inventories at the provincial and national levels.

Evaluating errors represents an important shortcoming of the teaching-learning evaluation process in every educational system. The purpose of this research was to investigate the causes, consequences, and approaches of solutions to eradicate the evaluating errors in Benin secondary schools. To that purpose, ten (10) teachers and 100 learners were chosen based on their willingness exclusively from GUEMA secondary school in the municipality of Parakou. The data were collected through questionnaires, interviews, group discussions, and past exam papers analysis. The findings revealed that exam paper errors are often due to the evaluating system that consists of machines. The mistakes concern miswritten words, special notes such as “NB,” “Note,” etc., ambiguity about items and questions, and unreadability of the paper. Consequently, evaluating errors impacts the learners’ present and future language careers. They make learners feel demotivated and stressed, damaging their eagerness to learn the language. To solve this issue, it was shown that English as a Foreign Language (EFL) teachers need in-service training and significant reforms in evaluating the system should be done.

Due to the high wastepaper recyclability and water-loop system closure, packaging paper mills struggle with increased fines, causing runnability issues. Cellulase enzymes are a preferred treatment choice for the improvement of the pulp refining in stock preparation area but are not widely used or easy to introduce in the production process. Different cellulase enzymes were tested, and those with the highest activity were introduced to the white-water (WW) samples with the aim to reduce fines content as potentially new enzyme applications on the paper machine. The first portion of the study involved the development of an experiment model to find and confirm the optimal enzyme process parameters (40 °C, pH 5.7, reaction time 3 h, and 0.18% v/v enzyme addition) for laboratory made white-water. The second portion of the study included turbidity, colloidal charge, flow cytometry (FCM), and chemical oxygen demand (COD) analysis on industrial and laboratory made white-water samples at optimized process parameters. Obtained results corresponded to reduced fines content in white-water samples, which justified commercial usage of cellulase enzymes on recycled paper machine short loop and potentially increased machine runnability without negative influence on wastewater treatment plant.

We present a method to fabricate handcrafted thermoelectric devices on standard office paper substrates. The devices are based on thin films of WS2, Te, and BP (P-type semiconductors) and TiS3 and TiS2 (N-type semiconductors), deposited by simply rubbing powder of these materials against paper. The thermoelectric properties of these semiconducting films revealed maximum Seebeck coefficients of (+1.32 ± 0.27) mV K−1 and (−0.82 ± 0.15) mV K−1 for WS2 and TiS3, respectively. Additionally, Peltier elements were fabricated by interconnecting the P- and N-type films with graphite electrodes. A thermopower value up to 6.11 mV K−1 was obtained when the Peltier element were constructed with three junctions. The findings of this work show proof-of-concept devices to illustrate the potential application of semiconducting van der Waals materials in future thermoelectric power generation as well as temperature sensing for low-cost disposable electronic devices. © 2022 The Authors.

Developing environmentally friendly barrier coatings as an alternative to petroleum-based polymer packaging is a challenge. Cellulose nanofibres (CNF) films have exhibited great potential as water and gas barrier layers. Recycled paper was multi-layer coated with three commercial CNF (mechanical (M-CNF), TEMPO (T-CNF) and carboxymethylated (C-CNF)) using two metering systems (wound rod and blade micrometer) and two drying methods (tension-free contact drying and air drying). The coatability and rheological behaviour of the CNF suspensions were analysed. The gas, water and grease barrier properties of the CNF coated papers were determined and compared with the results of paper coated with cationic starch. The three CNF suspensions and the starch suspension were successfully coated using both metering systems. In the multi-layer coating, air drying yielded higher coat weights than contact drying, and the difference was more noticeable in M-CNF and T-CNF coated samples. A lack of uniformity observed in CNF coatings increased with the number of coating layers. M-CNF coated samples had a whitish surface with a uniform appearance, but coating was insufficiently compact to provide barrier properties. T-CNF coating exhibited a cracked surface and consequently provided no barrier properties. Drying stresses caused breakage of T-CNF coating, which could be explained by the drop in apparent viscosity at much lower rheological shear stresses in the T-CNF suspension. C-CNF showed successful coatability and provided barrier properties to paper with both metering systems and drying methods. Air permeance decreased considerably and the water wettability of the paper decreased by 60% compared to the reference paper, even with a single coating layer (about 1 g·m−2). In addition, a greaseproof paper (grease resistance >1800 s and kit no >10) was obtained with multi-layer C-CNF coating. Although water vapour permeability at 90 % RH and 20 °C decreased slightly with a single layer of CN

Diagnosing immediate drug hypersensitivity reactions (IDHRs) can pose a significant challenge and there is an urgent need for safe and reliable tests. Evidence has emerged that the basophil activation test (BAT), an in vitro assay that mirrors the in vivo response, can be a complementary test for many drugs. In this position paper, members of Task Force (TF) “Basophil activation test in the evaluation of Drug Hypersensitivity Reactions” from the European Academy of Allergy and Clinical Immunology (EAACI) present the data from a survey about the use and utility of BAT in IDHRs in Europe. The survey results indicate that there is a great interest for using BAT especially for diagnosing IDHRs. However, there are still main needs, mainly in the standardization of the protocols. Subsequently consensus-based recommendations were formulated for: (i) Technical aspects of BAT in IDHRs including type of sample, management of drugs, flow cytometry protocols, interpretation of the results; and (ii) Drug-specific aspects that should be taken into account when performing BAT in relation to betalactams, neuromuscular blocking agents, fluoroquinolones, chlorhexidine, opioids, radio contrast media, chemotherapeutics, biological agents, nonsteroidal anti-inflammatory drugs, COVID vaccine, and excipients. Moreover, aspects in the evaluation of pediatric population have also been considered. All this indicates that BAT offers the clinician and laboratory a complementary tool for a safe diagnostic for IDHRs, although its place in the diagnostic algorithm depends on the drug class and patient population (phenotype, geography, and age). The standardization of BAT is important for generalizing this method beyond the individual laboratory., Diagnosing immediate drug hypersensitivity reactions (IDHRs) can pose a significant challenge and there is an urgent need for safe and reliable tests.
