Published: November 2024

This study evaluates the impact of positive emotions on rheumatoid arthritis (RA) treatment outcomes through a meta-analysis of 47 studies (2015-2024) involving 12,384 patients. The primary findings reveal a significant positive correlation between positive emotions and improved RA treatment outcomes (r = 0.42, p < 0.001), with the strongest effects observed in enhanced quality of life (r = 0.51) and physical function (r = 0.45). Patients exhibiting high positive emotions demonstrated greater reductions in pain (d = 0.38), decreased inflammation (d = 0.29), and improved physical function (d = 0.45) compared to control groups. Moreover, moderator analyses uncovered stronger effects among elderly patients (? = 0.012, p = 0.025) and those with longer RA duration (? = 0.018, p = 0.009). Finally, mediational analyses indicated that positive emotions contributed to improved treatment adherence (indirect effect = 0.09, 95% CI [0.05, 0.13]) and increased physical activity (indirect effect = 0.07, 95% CI [0.03, 0.11]) in RA patients. These findings extend Fredrickson's (2001) Broaden-and-Build theory and support Keefe et al.'s (2002) biopsychosocial model. Compared to meta-analyses by Brosseau et al. (2018) and Zhou et al. (2020), this study provides more comprehensive evidence on the role of positive emotions in various RA treatment outcomes. The novelty of this research lies in the analysis of previously unexplored mediating and moderating mechanisms, as well as a comparison of effectiveness with pharmacological interventions (SMD = 0.18, 95% CI [-0.05, 0.41], p = 0.124). These results support the integration of positive emotion-based interventions in RA management and expand upon Strand et al.'s (2019) findings on patient expectations in RA treatment.
The End of Philosophy and the Birth of a New Worldview : Rereading Ludwig Feuerbach and the End of Classical German Philosophy
Authors: Rong Caiwei
Published: November 2024

“终结”是贯穿《路德维希·费尔巴哈和德国古典哲学的终结》的关键线索。对“终结哲学”这类表述的理解在学术界引起过颇大争议，事实上，马克思与恩格斯要终结的决非历史文化意义上的哲学，而是过往凌驾于一切科学之上的“哲学”，为此他们展开了一系列工作，包括对黑格尔辩证法的创造性继承和批判，以及通过费尔巴哈这一中介实现向彻底的唯物主义的过渡，而他们得出的结果已经根本不再是哲学，而只是世界观。为了遵循马克思与恩格斯的本意，对这一新世界观的理解与运用也应脱离传统哲学固有的思维方式，要充分理解其革命性意义，这对走好中国特色社会主义道路，开启自由而全面发展的新世界有着重要指导作用。

在建党前夕，马克思主义者与各社会思潮的政治派别进行多次思想交锋，其中最具代表性的是对无政府主义思潮的批判。《共产党》月刊作为论战的主阵地，月刊围绕无政府主义国家观、革命手段、关于生产和分配的经济理论和极端个人主义观点四方面内容对无政府主义思潮展开批判。在这一过程中，《共产党》月刊以先进知识分子为批判主体，与《新青年》杂志形成多向互动，兼顾批判的学理性与实践性。这为我们在新时代辩证分析世界形势新变化、批判各种错误社会思潮和捍卫马克思主义的真理性提供了启示。
The Fourth Cognitive R/Evolution
Authors: Flatt Steve
Published: November 2024

Humans are at a turning point in their evolution. Many individuals and groups realise that there is need for change. This paper illustrates the difficulties evolution has created in human thinking, consequently producing many of the hurdles we face today.

Linear problem-solving thinking is no longer adequate when creating a sustainable ecology, economy or society. Humans must look beyond the problem, and be creative about what kind of a world is wanted. Resolving problems using competition and conflict is not effective. Effective change will only take place by using cooperation, community and connection to develop a sustainable world. The paradigm shift in thinking is from problem-focused to possibility-focused approaches.

Published: November 2024

Access to credit is an important thing in improving the livelihoods of rural families in developing international locations, enabling them to triumph over monetary barriers and spend money on productive activities. This observation evaluates the impact of microcredit on the livelihoods of rural farming households in Southwest Nigeria, specializing in assets of credit and elements influencing credit access. Descriptive facts and multinomial logistic regression were used to analyse the information. Results show that informal credit sources, such as family and friends, are predominantly utilized by 97.5% of respondents, while only 8.3% accessed microfinance banks. The average credit amount received was ₦167,000, with limited utilization primarily due to constraints like market access and lack of technical knowledge. Agricultural activities such as crop production and livestock farming dominate rural livelihoods, suggesting that microcredit plays a crucial role in improving productivity. However, findings indicate that higher education levels, income, and household size significantly influence the likelihood of accessing formal and informal credit. The study concludes that microcredit has the potential to improve rural livelihoods, but formal credit systems must be expanded to reduce reliance on costly informal sources and enhance the overall welfare of rural households.

Authors: Zlateva Penka , Yordanov Krastin , Petkova-Slipets Rositsa , Ivanov Martin
Published: November 2024

The presented study reveals the analysis of the thermal behaviour of double skin facades (DSF) in winter conditions, using numerical simulation tools. The aim of the study is the development of a 3D simulation model, capable to evaluate the thermal behaviour of the modular elements in the DSF systems. This is essential requirement in the prediction and visualization of the facade’s thermal behaviour in the design stage and in the assessment of the real behaviour of such facade, when the specified modular elements are changed by the customer. The presented numerical simulation model aims to adequately reproduce the resulting set of thermal characteristics of the modular elements, to determine with sufficient accuracy their distribution in the real objects, implemented inthe models in DSF systems. An algorithm is developed in the study and graphical visualization of three models of double facade systems with and without DSF are analysed under winter conditions, using data from a meteorological station located in North-Eastern Bulgaria. A software product was used to represent the processes of heat and mass transfer, in which the corresponding boundary and initial conditions were set, based on which the results and analyses were obtained. The use of such numerical modelling is effective enough to predict the expected thermal behaviour of DSF systems. Thus, when selecting a DSF facade system, awareness of the thermal behaviour is ensured, and the financial efficiency of the project is more easily determined. Such a customized approach not only improves the sustainability and efficiency of buildings, but also satisfies the unique preferences and requirements of the customers.

Authors: Georgieva Adriana Asenova , Yovkova Fila Slavova , Georgieva Margarita Anatolievna , Markovska Irena Georgieva
Published: November 2024

In the present paper, the effect of the addition of graphene nanostructures and 3 mass % TiO2 on the microstructure and properties of sintered corundum ceramics were studied. Fine-porous corundum ceramics were obtained by the method of solid-phase sintering at relatively low temperatures of 1450oC, by adding graphene nanostructures in an amount of 2 % or 20 %. To lower the synthesis temperature, 3 mass % TiO2 was added to the initial ceramic blends. As a result of the solid solution formed between Al2O3 and TiO2, a well-sintered corundum ceramic is obtained at synthesis temperature lower than that of pure corundum - 1450oС. For the characterization of the initial blends and the ceramic samples, the methods of X-ray phase analysis, infrared spectroscopy, SEM, TEM EDS and visual microscopy were used. Besides, the basic physicochemical properties of the samples synthesized based on corundum were determined, e.g. water absorption (WA, %), apparent density (AD, %) and apparent (open) porosity (Pa, %).

A COMPARATIVE STUDY OF THE SURFACE OF FACTORY AND HAND-MADE LOOPS ON TITANIUM-MOLYBDENUM ORTHODONTIC ARCHWIRE
Authors: Yordanova Rozina
Published: November 2024

The most important part of the brackets, used in orthodontic treatment, is the archwire, which, when activated, generate light and long-lasting biomechanical forces that make the teeth move. Different manufacturers offer ready-made expensive solutions for orthodontists - archwire with loops along the length of the wire of different shape, which increases the cost of treatment. However, orthodontic practice is strictly individual, depending on the patient’s orthodontic problems, the stages and methods of treatment.Orthodontists often have to choose between expensive archwires with pre-made loops or using an archwire that they can manually bend in the right places depending on the patient’s individual characteristics and specific needs. In this case, the orthodontist’s decision depends on preserving the quality of the archwire surface. The surface roughness of the orthodontic archwire plays an important role in the bracket-archwire complex and is an essential factor that determines the effectiveness of the guided movement of the teeth along the arch. Surface roughness not only affects the efficiency of sliding mechanics, due to frictional effects, but also corrosion behaviour and aesthetics. A comparison of the surface characteristics of Ti-Mo archwire - with factory and hand-made loops is made. The surface of the archwire in the bending zones of the loops was investigated by SEM analysis and Surface roughness analysis. The analysis of the results shows that manual bending practically does not change the surface of the archwire, does not introduce additional defects that increase the contact friction, as well as create conditions for faster deterioration of properties and the undesirable breakage of the archwire. Research results give orthodontists confidence that the manual bending process does not degrade the quality of the archwire surface. The hand-bent archwire preserves the possibility of trouble-free movement in the braces when tightening or loosening during the different stages of treatment.

Based on new findings at Polideportivo de Martos (Jaén) and Los Millares (Almería) sites, a review of the “plate idols” from the Southeast Iberia is carried out. The applied methodology has included the stylistic analysis and the evaluation of the provenance contexts allowing us to make some interpretative proposals. Thus, a relationship is observed between the formal variety and the geographical distribution, with respect to those of Los Millares necropolis. Also, the connection of the similarities with the contacts between social groups is shown. Finally, the role that the circulation of people, especially of certain women, played in the configuration of a relatively common ideology in Southern Iberia. “Plates” played a transcendent role in establishing the connection of certain people with ancestors (generic or particular) either by their integration in the funerary ritual, or by their (re)use as relic-ornament, or by their mobilization in ceremonials of agrarian regeneration. Its use developed from the middle of the 4th millennium BC.

Presentamos una revisión de los “ídolos placa” del Sureste de la península ibérica tras los nuevos hallazgos del Polideportivo de Martos (Jaén) y Los Millares (Almería). El análisis estilístico y contextual ha permitido diferentes valoraciones. Así, se observa una relación entre la variedad formal y la localización geográfica respecto a la distancia a la necrópolis millarense. Igualmente, se aprecia la conexión de las similitudes con contactos entre grupos sociales. Con todo, se plantea el rol que la circulación de personas, especialmente de determinadas mujeres, tuvo en la configuración de una ideología relativamente común en el sur de la península ibérica. Las “placas” desempeñaron un papel trascendente en la conexión de determinadas personas con los ancestros (genéricos o particulares) sea por su integración en el ritual funerario, sea por su (re)uso como reliquia-ornamento, o por su movilización en ceremoniales de regeneración agraria. Su uso se desarrolló desde mediados del IV milenio cal AC.

DESMISTIFICANDO O PAPANICOLAU: UM OLHAR SOBRE SUA IMPORTÂNCIA E BAIXA ADESÃO
Authors: Carpes Sauer André , Aíram Rosa de Oliveira Silva Lunna , Massimo de Oliveira Silva Weverton , Marx Soares de Araujo Thales
Published: November 2024

Introdução: O câncer do colo do útero (CCU) é uma doença grave que afeta cerca de 16 mil brasileiras anualmente, com uma tendência de crescimento nos próximos anos. Afeta mais de um milhão de mulheres no mundo, sendo o terceiro tumor mais frequente nesse público. Os altos índices estão também relacionados à baixa adesão ao Papanicolau, método simples e barato que detecta alterações precoces, aumentando as chances de cura. Objetivo: Realizar uma revisão integrativa da literatura para identificar e analisar as práticas e estratégias recomendadas pelo sistema de saúde e profissionais, visando desmistificar este procedimento e os obstáculos que dificultam ou atrasam a adesão das brasileiras adultas. Metodologia: Consultaram-se as bases de dados Lilacs, PubMed, Scielo e Google Acadêmico, selecionando artigos relevantes, destacando-se trabalhos publicados entre 2014 e 2024. Resultados e Discussões: A baixa adesão ao exame Papanicolau é um problema multifacetado, no qual vários fatores apresentam-se como obstáculos. Para tanto, mulheres costumam destacar principalmente dificuldades socioeconômicas e questões pessoais, como justificativas para a não realização deste procedimento. Desse modo, enfatiza-se a necessidade de ações educativas pelas equipes de Saúde da Família, promovendo o conhecimento sobre sua importância, abordando medos e tabus e respeitando as particularidades de cada paciente. A comunicação clara e acessível, o respeito à cultura e o atendimento humanizado são fundamentais para promover a adesão ao Papanicolau. Considerações Finais: Os dados sobre a decadente adesão ao Papanicolau e o crescimento nos diagnósticos de CCU geram temor mundial. Mulheres destacam-se como fatores impeditivos as questões socioeconômicas e a timidez. Reconhecer esses desafios é crucial para desenvolver soluções eficazes, reduzir desigualdades sociais e aumentar a cobertura médica. Além de medidas educativas, é importante abordar individualmente as barreiras, implementar programas de conscientização, campanhas vacinais contra HPV, uso de testes de DNA-HPV e consolidar a implantação da CML para reduzir taxas de amostras insatisfatórias e evitar atrasos no diagnóstico.

The aim of the study is to determine the evapotranspiration by stages of development, with which, in an indirect way, quickly and easily predict and manage the irrigation regime of head celery. A field experiment was conducted with celery in the Plovdiv region, grown under irrigated conditions. There are six options, irrigated with different irrigation rates, are set as follows: option 1) 130%, option 2) 100%, option 3) 70%, option 4) 50% and option 5) 30% of the calculated rate, option 6) without irrigation. In the hypothetical optimal variant, a pre-irrigation humidity of 80% of the FC (field capacity) was maintained in the 0-40 cm layer. The development period is divided into three sub-periods: 1 - from the interception of seedlings to the beginning of root formation; 2 - beginning of growth of the root crop and 3 stage - Intensive growth until harvesting. ETc was established by phases of development for celery, and in the layer 0-0.4m a maximum (3.8 and 4.42) was recorded in phase 2 - the beginning of the formation of the root crop, respectively for the variants irrigated with 100% and 130 % of the norm. With the same options, but at a depth of 0-0.5m ETc is 4.81 and 5mm. In the first phase of development, celery spends about 155 mm in variants 1 and 2, between 110 and 95 in variants 3 and 4 and between 78 and 60 mm in variants 5 and 6.

A three-year field experiment was conducted with celery under irrigated conditions in the Plovdiv region 42° 08‘ 06“ N024° 44‘ 43“ E and 160 m above sea level. The purpose of the development is to establish the biophysical coefficients (Z, R and Ks) of the evapotranspiration of the crop and to recommend the most suitable ones for managing the irrigation regime. The experiment spanned three distinct years, each characterized by varying climatic factors. Throughout all three years, vegetation precipitation was insufficient and unevenly distributed. Post statistical analysis, they were defined as wet, medium and dry. The soil is an alluvial meadow with a bulk density of 1.33 g/cm3 for the 0-0.4m layer where soil moisture was monitored. Real evapotranspiration data of celery, obtained via the weight-thermostat method with regular soil sampling, were used. Three phases of celery development are distinguished, the first being from the interception of seedlings to the beginning of the formation of the root crop, the second - covering the beginning of growth of the root crop and the third phase - from intensive growth to harvest. The Z-factor values by phase were 0.14, 0.21, and 0.24 for R – 0.24, 0.4 and 0.6, and for Kc – 0.65, 1.01 and 1.51.
