With the continuous development of the times, the transformation and reform of higher education has brought many problems. In this paper, we carry out research on the transformation of higher education, put forward the educational reform path based on the theory of organizational experiment, improve the higher education management model based on the three-dimensional integration, and construct the campus education management system based on the multilayer network by combining with the needs of campus management. On this basis, an evaluation model oriented to multilayer network is established by using association matrix and probabilistic transformation, which is utilized to evaluate the system, and comparative education management experiments are designed to test the application effect of the constructed system. In this paper, the response time of the educational management system using multilayer network is 0.35~0.80s, which is about 0.45s faster than that of the traditional system, and about 0.26s faster than that of the single-layer network controller. The students using this educational management system have improved their interest cultivation, innovation ability, cooperation ability, and scientific attitudes in comparison with the pre-application ones, which are 3.534, 2.452, 2.721, and 2.51, respectively, 2.721 and 2.51.The higher education management model proposed in this paper can have the ability to improve students’ competence level and provides an effective path for the reform of higher education management.
Theoretical and Legal Principles of Interaction between Public Authorities and the Public Under the Legal Regime of Martial Law

Published: May 2024

The concept of civil society became relevant again at the end of the twentieth century due to the development of democratization, digitalization, and globalization. Today, the issue of public participation in addressing issues of public importance is increasingly associated with electronic petitions, public consultations and discussions, public expertise, etc. The problem of interaction between public authorities and the public in the field of regional planning requires a broad interdisciplinary understanding not only at the level of infrastructure projects, but also in the field of mobilization training and mobilization, identification and solution of humanitarian problems of the population in the de-occupied territories under martial law. Along with public authorities and the public, the world of technology and artificial intelligence is gaining more and more independence, which is becoming more and more independent of the regulatory and coordinating influence of a person, organization, or state from the platform of interaction, the object of influence. At the same time, social networks are reaching an increasing number of people and are being monetized, which necessitates a more comprehensive, strategic vision of the interaction of public authorities with social networks. For the sake of better understanding of the theoretical and legal framework for interaction between public authorities and the public under martial law, an attempt was made to comprehend the problems that occurred in the field of public relations under study before the introduction of martial law in Ukraine, and which also emerged as a new challenge during the period under study, generating the relevant social transformations.

The purpose of this article is to outline criminal procedural and forensic means of collection and examination of physical documents in Ukrainian criminal justice. The linguistic analysis, formal-legal, formal-logical, modeling, forecasting methods, as well as the praxeological approach in forensic science are used. The authors argue that a document, as a material object, must be obtained in a manner permitted by law and examined using the necessary forensic means in order to acquire evidentiary status and be suitable for use in criminal proceedings. It was established that the procedural status of a document depends on its internal and external features. If the content of the document carries evidentiary information, it is considered written evidence; if such information is carried by its external (material) features, it is physical (real) evidence. Procedural means of collecting documents are defined by Art. 93 of the Criminal Procedure Code of Ukraine and differ for the parties to the proceedings. Preliminary, judicial and expert examination of documents is distinguished. The main stages of the preliminary examination of documents and the necessary technical means are described. It is emphasized that Ukrainian judges avoid using their own special knowledge when examining documents. Some features of the appointment of forensic examinations of documents and evaluation of their conclusions are highlighted. The perspective of the study of methods of using documents as evidence has been established.

Published: May 2024

El burnout académico es una respuesta emocional negativa persistente, relacionada con las actividades académicas universitarias, formada por una sensación de agotamiento, una actitud cínica con el significado y la utilidad de los estudios, y un sentimiento de baja eficacia académica como estudiante universitario. Por ello, el objetivo de la presente investigación fue determinar la prevalencia de burnout académico en estudiantes universitarios de una universidad pública de Perú. El enfoque de investigación fue cuantitativo, no experimental, de corte transversal y de alcance correlacional. La muestra estuvo compuesta de 402 estudiantes universitarios a quienes se les aplicó el inventario de Maslach Burnout Inventory-Student Survey (MBI-SS) con alta fiabilidad (α=0,865). Los resultados muestran que el nivel de burnout académico fue moderado (67,7%). En cuanto a sus dimensiones, los estudiantes se caracterizan por presentar agotamiento emocional, cinismo y eficacia académica moderado. El agotamiento emocional más frecuentes fueron “Me siento agotado al final de un día en la universidad” (54,8%), “Me siento emocionalmente agotado por mis estudios.” (50,3%). La manifestación de cinismo con mayor recurrencia fue “Me he vuelto menos entusiasta con mis estudios” (39,6%), “Desde que me matriculé en la universidad me interesan menos mis estudios” (39,3%). La eficacia académica con mayor frecuencia fue “Durante las clases me siento seguro de ser eficaz en la realización de las cosas” (41,5%), “He aprendido muchas cosas interesantes a lo largo de mis estudios” (39,2%). Se concluye que los estudiantes universitarios de ambos sexos presentaron un nivel de burnout académico moderado en las dimensiones y en la valoración global.

Self-inhibiting percolation and viral spreading in epithelial tissue
Authors: Xu Xiaochan , Nielsen Bjarke Frost , Sneppen Kim
Published: May 2024

SARS-CoV-2 induces delayed type-I/III interferon production, allowing it to escape the early innate immune response. The delay has been attributed to a deficiency in the ability of cells to sense viral replication upon infection, which in turn hampers activation of the antiviral state in bystander cells. Here, we introduce a cellular automaton model to investigate the spatiotemporal spreading of viral infection as a function of virus and host-dependent parameters. The model suggests that the considerable person-to-person heterogeneity in SARS-CoV-2 infections is a consequence of high sensitivity to slight variations in biological parameters near a critical threshold. It further suggests that within-host viral proliferation can be curtailed by the presence of remarkably few cells that are primed for IFN production. Thus the observed heterogeneity in defense readiness of cells reflects a remarkably cost-efficient strategy for protection.
Comparison of Tug-of-War Models Assuming Moran versus Branching Process Population Dynamics
Authors: Dinh Khanh N. , Kurpas Monika K. , Kimmel Marek
Published: May 2024

Mutations arising during cancer evolution are typically categorized as either ‘drivers’ or ‘passengers’, depending on whether they increase the cell fitness. Recently, McFarland et al. introduced the Tug-of-War model for the joint effect of rare advantageous drivers and frequent but deleterious passengers. We examine this model under two common but distinct frameworks, the Moran model and the branching process. We show that frequently used statistics are similar between a version of the Moran model and the branching process conditioned on the final cell count, under different selection scenarios. We infer the selection coefficients for three breast cancer samples, resulting in good fits of the shape of their Site Frequency Spectra. All fitted values for the selective disadvantage of passenger mutations are nonzero, supporting the view that they exert deleterious selection during tumorigenesis that driver mutations must compensate.
School Counsellors’ Professional Practice in Health Promotion, Prevention and Remedial Work in Swedish Schools
Authors: Jansson Per
Published: May 2024

According to the Swedish Education Act, schools in Sweden must provide comprehensive student health services to foster an inclusive and conducive learning environment, promoting students’ well-being and knowledge development. As part of a multi-professional team, school counsellors are essential in achieving these goals. However, national guidance lacks details on the role of school counsellors in health promotion, prevention and remedial efforts. This study addresses this knowledge gap by examining aspects of school counsellors’ professional work using theories of professions. Open-ended answers in a survey distributed to school counsellors in Sweden were analysed through content analysis. Findings show that remedial work primarily focuses on individual students’ social issues through conversation-based interventions. Preventive work targets groups and the broader school environment, often involving tasks like policy development. Health promotion work stands out with its educational component, where school counsellors are involved in Life Competence Education, often in collaboration with other school professionals.

Published: May 2024

A study was carried out in the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh, Bangladesh to investigate the impact of spacing on the growth and yield of Boro rice cv. BRRI Dhan47. The experiment consisted of four spacings viz. 25 cm × 10 cm, 25 cm × 15 cm, 25 cm × 20 cm and 25 cm × 25 cm as treatment. The experiment was laid out in a randomized complete block design with three replications. Spacing significantly influenced most of the parameters except plant height, panicle length and weight of 1000 grain. The highest number of total tillers hill-1, non-effective tillers hill-1, sterile spikelets panicle-1, total spikelets panicle-1 (146.07) and straw yield were obtained from 25 cm × 25 cm spacing. But, the maximum number of effective tillers hill-1, grains panicle-1 (125.40), grain yield (5.05 t ha-1), biological yield (11.22 t ha-1) and harvest index (44.86%) were recorded from 25 cm × 15 cm spacing. The lowest value of the above-mentioned characters was obtained from 25 cm × 10 cm spacing in most of the cases except minimum non-effective tillers hill-1 and number of sterile spikelets panicle were obtained from 25 cm × 15 cm spacing and the lowest harvest index (41.14%) was recorded from 25 cm × 25 cm spacing. Based on the findings of the study, it can be suggested that the use of 25 cm × 15 cm spacing would be a promising practice to improve growth and maximize the grain yield of BRRI dhan47.

Authors: Salova Maelyn L. , Samperoy Jenica R. , Llorente Hazel Mae C.
Published: May 2024

This study aimed to determine the relationship between organizational justice and employee retention in banana companies. A quantitative approach with descriptive and correlational designs was used. The respondents of the study were 89 employees working in two banana companies in the Municipality of Santo Tomas. The respondents were selected through convenience sampling technique. Mean and Pearson-r were used to analyze the data, which were obtained through the use of two adapted questionnaires. The findings revealed that organizational justice in terms of distributive justice, procedural justice, and interactional justice is always manifested in banana companies. On the other hand, employee retention in terms of a positive work environment, employee freedom and flexibility, employee involvement and growth, employee communication and assistance, and compensation and benefits are always manifested, too. The result indicated that there was a significant relationship between organizational justice and employee retention in banana companies. The findings suggested that banana companies may prioritize a fair distribution of workloads based on employees' skills and experience to ensure fairness. Management may have regular team outings or social events for building relationships and conducting frequent trainings, which shows the organization's commitment to employee growth. Future researchers may conduct studies investigating factors or mediators such as job satisfaction, organizational commitment, and leadership styles, which may help in gaining insight into the deeper processes in this relationship.

The aim of the present study was to evaluate the yield, digestibility, and protein content of nine varieties of alfalfa (Medicago sativa L.). The varieties of alfalfa were compared during a complete production cycle. A completely randomized design was used taking into account the season of the year as a block and the varieties as treatment, a Tukey test was used to evaluate differences between treatments. The highest dry matter (DM) production was in the summer, with Atlixco variety being the highest yield (1953.3 kg DM cut-1), the ratio leaf:stalk (L:S) was highest during the winter, with no differences (p>0.05) between varieties. The varieties with highest protein content (PC) was Caliverde and Valenciana (22.9 % PC) during the winter (p<0.05). The highest digestibility was in the summer and there were no differences between varieties. The higher amount of digestible dry matter (DDM) and PC were produced by Valenciana (1586.7 kg DDM cut-1 and 446.7 kg PC cut-1), UC-Cibola (1557.0 kg DDM cut-1 and 432.3 kg PC cut-1) and Atlixco (1549 kg DDM cut-1 and 441.1 kg PC cut-1). The highest dry matter production was during the summer and spring, the three most productive varieties were Valenciana, Atlixco and UC-Cibola, and therefore these are the most suitable varieties for the best quality forage production in the region of study.

A confiança é a base sobre a qual a democracia é construída. Não por acaso, é a principal vítima dos ataques de mercadores da desinformação empenhados em minar o processo eleitoral e o ambiente democrático. Em um ambiente de grande disseminação de desinformação contra o processo eleitoral e as instituições envolvidas, a Justiça Eleitoral brasileira construiu um ousado programa de enfrentamento com o objetivo de combater os efeitos da desordem informacional em seu processo democrático. Este artigo detalha as iniciativas adotadas pelo TSE e suas parcerias com plataformas digitais e com a sociedade civil para garantir a transparência e construir confiança e integridade nos processos eleitorais no Brasil.
O FIM DAS COLIGAÇÕES ELEITORAIS NAS DISPUTAS PROPORCIONAIS: para onde foram os partidos políticos nas eleições de 2022?
Authors: Vasquez Vitor , Sandes-Freitas Vítor Eduardo Veras de , Santana Luciana
Published: May 2024

A Emenda à Constituição (EC) nº 97/2017 estabeleceu o fim das coligações para disputas proporcionais. As eleições municipais de 2020 foram as primeiras a ocorrer sob a nova norma, quando foi possível observar uma redução na fragmentação das câmaras de vereadores (Santana, Vasquez, Sandes-Freitas, 2021). As mudanças passaram a valer para os legislativos estaduais e para a Câmara dos Deputados na eleição de 2022. Esse artigo tem como objetivos analisar o impacto desta mudança de regra sobre os partidos políticos brasileiros em termos de lançamento de candidaturas e de resultado eleitoral e investigar seus efeitos sobre a fragmentação partidária. Para tanto, analisamos dados das disputas para deputado federal em duas eleições anteriores à mudança institucional (2014 e 2018) e outra com a nova legislação já vigente (2022). Os dados foram retirados do Portal de Dados Abertos do Tribunal Superior Eleitoral e foram investigados por meio de estatística descritiva e inferencial. Nossos resultados apontam que a EC nº 97/2017 reduziu a fragmentação partidária, os partidos se anteciparam aos efeitos da emenda, alterando o padrão de candidatura e os partidos pequenos tiveram suas chances de eleger parlamentares reduzidas.
Crystallization
Authors: Ulrich Joachim , Stelzer Torsten
Published: January 2011

This article provides an overview of crystallization that can be used by scientists and engineers, regardless of their familiarity with the operation. Key aspects of using crystallization for separation, purification, or other purposes are covered; especially noteworthy is the coverage relating product purity, morphology, polymorphs, solvates, and size distribution to the kinetic phenomena of crystal nucleation and growth. Current studies have shown that crystallizer variables such as mixing and the rate at which supersaturation is generated influence the purity of recovered crystals. Crystal morphology can be affected by variables modifying inherent growth kinetics of crystal faces or by changing interfacial or solution properties. Molecular modeling is a tool to understand and predict morphologies or changes of morphologies due to additives/impurities. Theory is mixed with empiricism in showing the role of operating variables (supersaturation, magma density, and agitation) in determining crystallization kinetics. Methods are illustrated for coupling crystallization kinetics with population balances on continuous and batch crystallizers to determine crystal size distributions. In addition, the bases of using selective removal functions (clear–liquor advance, classified fines removal, and classified product removal) to influence the characteristics of size distributions are presented. Qualitative characteristics of batch crystallizers are presented and the role nucleation plays in determining the general behavior of product size distributions from such system is described. Furthermore, a summary of industrial practice and equipment (solution and melt crystallization) is presented. Finally, brief reviews are given to the emerging importance of preferential crystallization, eutectic freeze crystallization as well as the crystallization of proteins.
Sodium Carbonate
Authors: Eggeman Tim
Published: January 2011

Sodium carbonate, also known as soda ash, is an alkali chemical refined from the mineral trona or naturally occurring sodium carbonate brines. The product is called natural soda ash. Synthetic soda ash is manufactured by several chemical processes. Production from trona and the Solvay synthetic process account for the vast majority of current capacity. The United States has the world's largest deposit of trona. Sodium carbonate is a moderate health hazard. The major use of soda ash is in the manufacture of glass. Other uses are the manufacture of chemicals, in detergent formulations, flue gas desulfurization, and in the production of paper and pulp
Inventory Inaccuracies In Supply Chains: How CanRFIDImprove The Performance?
Authors: Rekik Yacine
Published: January 2011

Inventory inaccuracy occurs when the information system (IS) inventory, that is, what, according to the IS, is available, does not match the physical inventory, that is, what is actually available. The IS inventory, contrary to popular belief and assumptions in most academic papers and in spite of the considerable amounts invested in information technology, is often inaccurate. In this article, we first describe the major factors generating inventory inaccuracy. Then, we present main solutions that allow tackling the inaccuracy issue. We also provide a framework that permits modeling the inventory inaccuracy issue and focus on the impact of an advanced identification system such as radio‐frequency identification (RFID) technology in improving the performance of a supply chain subject to inventory inaccuracies.
On the allocation of new lines in a competitive transit network with uncertain demand and scale economies
Authors: Li Zhi‐Chun , Lam William H. K. , Wong S. C.
Published: January 2011

This paper proposes a new model for investigating the allocation of new lines in a competitive transit network in which transit operations are subject to demand uncertainty and scale economies. Scale economies imply that the operating cost of each operator per unit of transit line decreases with the number of lines operated. The proposed model explicitly considers the interactions among three types of players: transit authority, transit operators, and transit passengers. The transit authority aims to maximize the total social welfare for a given confidence level (or probabilistic guarantee) by optimizing the allocation of new lines to bidding operators. For a given allocation scheme, each of the operators determines the associated frequencies and fares to maximize its own profit at a certain confidence level while accounting for the responses of transit passengers to their strategies. The proposed line allocation model is formulated as a robust 0–1 integer programming problem that can be solved by an implicit enumeration algorithm. A numerical example is presented to illustrate the effects on the transit system of the allocation of new lines, the scale economies, the level of variation in passenger demand, and the risk attitude of transit operators toward uncertainty.

Simulation‐based analysis of personal rapid transit systems: service and energy performance assessment of the Masdar City PRT case
Authors: Mueller Katharina , Sgouridis Sgouris P.
Published: January 2011

Masdar City a zero‐emission model city, is implementing a fully automated on‐demand personal rapid transit (PRT) system for its intracity transportation needs. The car‐sized electric vehicles will run on an underground road network transporting passengers and freight throughout the city. A discrete‐event PRT simulation model (miPRT) is built to support the design and implementation of the first city application of this innovative system. Through simulation, we estimate the impact of different vehicle allocation algorithms, battery charging strategies and vehicle occupancy rates and anticipate the system's behavior under stress loads to rate its capacity limitations under travel demand surges due to special events as well as track close‐down scenarios. The simulation model assists in improving fleet utilization, energy consumption, and overall system costs. Beyond the specifics of this implementation, this paper provides a tool for testing wider adoption of the PRT concept. Copyright © 2011 John Wiley & Sons, Ltd.

Published: January 2011

Ruthenium alkylidene complexes, based on second generation Hoveyda–Grubbs catalysts, have been directly attached to silica through covalent Ru‐O‐Si bonds, characterized by using cross polarization magic angle spinning 13C NMR (CP MAS 13C NMR) spectroscopy, and proved active in selected metathetic transformations. The complexes can be easily recycled and subsequently reused. In the ring closing metathesis (RCM) reaction of diethyl diallyl malonate the heterogenized complex can be recycled up to 15 times.
The quality of stakeholder engagement in sustainability reporting: empirical evidence and critical points
Authors: Manetti Giacomo
Published: January 2011

The aim of the article is to investigate the quality of stakeholder engagement (SE) in sustainability reporting (SR). The first part analyses the role of SE in SR according to the literature: SE is a fundamental step of the reporting process because of its role in defining materiality and relevance of the information communicated. The second part of the paper is dedicated to an empirical analysis of a sample of sustainability reports. The analysis showed that what is really applied in a wide majority of the cases is a stakeholder management approach rather than an SE approach. In the light of the above, questions for the future are if SE is moving from being a simple way to consult and influence stakeholders to an effective instrument for involving them in the company's decision making, through a mutual commitment.
