Authors: Zhang Qianqian , Maru Apurv , Yang Chengji , Guo Hongdong
Published: December 2024

Although the widespread use of the Internet in rural areas provides new opportunities for economic growth, whether and how rural women benefit from it remains a question. Guided by Sustainable Development Goal (SDG) 5 and its targets, this study examines the impact of Internet use on rural women’s income by using survey data from 1384 rural households in underdeveloped areas of China. The results indicate that Internet use can significantly increase rural women’s income in underdeveloped areas. Additionally, the income effects of Internet use are heterogeneous across the different purposes of Internet use, income levels, individual characteristics, and family characteristics. Further analysis reveals that increasing labor input and enhancing capital endowment are two important channels through which Internet use increases rural women’s income. The results offer further empirical support for policymakers to utilize the Internet to increase rural women’s income and contribute to poverty alleviation in underdeveloped areas.

Authors: Zhang Jie , Ou Zixin , Sun Yimeng
Published: December 2024

This study considers Jinniu Lake (JNL), the biggest artificial lake and National Water Conservancy Scenic Spot (WCSS) in Nanjing, as an example to analyze the determinants of tourists’ willingness to pay (WTP) and satisfaction, as well as their pro-environmental behavior from a ‘tourist perceived value’ perspective (i.e., function, emotional, social, and epistemic), and then estimate the non-use value of JNL using the contingent valuation method (CVM). A total of 321 valid responses to questionnaires were analyzed using structural equation modeling (SEM) with the obtained results indicating the following: (1) JNL possesses a relatively high non-use value, influenced by emotional value, function value, social value, and epistemic value. (2) Satisfaction mediates the relationships between perceived value and WTP. (3) Education level, monthly travel frequency, and past visit frequency are all significantly positively correlated with WTP. In conclusion, strengthening tourists’ emotional and functional identification within destinations is conducive to improving visitor satisfaction and inspiring their pro-environmental behavior, ultimately feeding back into the development of the scenic area through WTP, achieving imitable ecological–economic circular development.

In recent years, noise levels in administrative buildings have been considered one of the main causes of the stress and lack of productivity of employees. Based on the responses collected from a questionnaire survey distributed among companies with an open space configuration and studying the office’s acoustic conditions, from the specialized literature and through the authors’ experience, this study focused on the development of a new green dividing panel with superior sound absorption and acoustic insulation performances. In the experimental part, it was noticed that the presence of plants can influence the acoustic absorption values through their leaves’ conformation and distribution. Additionally, it was observed that the introduction of a coconut fiber layer in the panel led to higher values of the sound absorption coefficients in most of the studied plants. Through the conducted measurements, Tradescantia pallida registered superior values, with sound absorption coefficients with constantly increased values that varied in the range of 0.72–0.98 for the frequency range of 250–3150 Hz. Also, the weighted sound reduction index recorded a superior value of Rw (C; Ctr) = 27 (−1; −4) dB, comparable to other existing solutions.

Published: December 2024

The number of bridges in China is increasing year by year. The contradiction between the declining performance of bridge structures and the increasing traffic volume in China is becoming increasingly prominent, causing a concentrated upsurge in operation and maintenance needs during the service life of the bridges. In accordance with the goal and vision of the comprehensive construction of the Bridge Structural Health Monitoring (BSHM) system, the study of bridge cost-effectiveness now focuses on the installation, operation, and maintenance costs of the BSHM system, the renovation costs of bridge structure repair and maintenance, and the benefits of the BSHM system in assisting in expansion of the service life of bridges. In this study, a new cost-effectiveness framework is proposed that could be used for the operation and maintenance period. The cost-effectiveness framework is constructed from five perspectives: installation, operation, and maintenance costs of the BSHM system; repair and renovation costs during the operation and maintenance period; demolition costs; operation benefits during the operation and maintenance period; and the recovery benefits. The difference between costs and benefits is calculated to evaluate the cost-effectiveness, the service life, and the structural reliability of bridges, in order to provide auxiliary decision making for bridges. A bridge in China is used as an example; the difference between the reliability and operation of the bridge and the maintenance benefits and costs corresponding to different operating times is calculated, and maintenance decision analysis is performed. This can greatly extend the service time of the bridge without major repairs when the bridge reliability meets the requirements. Therefore, the BSHM operation and maintenance cost-effectiveness framework reduces resource waste, reduces operation and maintenance costs, and maximizes resource utilization and benefits, while ensuring the safety of the bridge structure and extending the service life of the bridge.
Enhancing Agricultural Ecology and Food Sustainability in the Yangtze River Economic Belt: An Integrated Evaluation Approach
Authors: Gan Lili , Hu Xiangling , Motwani Jaideep
Published: December 2024

This research critically examines the relationship between agricultural ecological protection and the sustainability of food production within the Yangtze River Economic Belt, a crucial area for China’s environmental and food sustainability. By developing a comprehensive evaluation framework, this study utilizes various analytical tools, such as entropy weight, comprehensive index models, coupling degree, coupling coordination, and relative development degree, to assess the interaction and degree of correlation influencing these systems. Key findings indicate that while the ecological protection index slightly declined from 2002 to 2022, indicators of food sustainability and overall development trended upwards, albeit with fluctuations. The study reveals an overall positive coupling degree and an increasing trend in coordination between ecological protection and food sustainability. The coordination index plays a crucial role in improving coupling coordination, and at the same time ecological factors play a more important role in this dynamic than factors related to food sustainability. In addition, this study identified stages of maladaptation and uncoordinated levels which further help to understand the complexity of the problem. The results underscore the need for improved strategies to manage the interplay between these critical domains, enhancing both ecological conservation and food sustainability.

Authors: Saglam M. Selman , Yilanci Veli , Tunc Ahmet , Saritas Merve Mert
Published: December 2024

This study investigates the potential impact of China’s dominant position in global tungsten production on its national economic growth, examining the applicability of the resource curse hypothesis. While prior research has extensively explored the resource curse in relation to oil and other resources, the role of tungsten remains largely unexplored. Utilizing annual data from 1994 to 2022, this study employs an autoregressive distributed lag (ARDL) bounds testing approach to analyze the long-run relationship between per capita income from tungsten production and per capita GDP. The results reveal a significant negative relationship, suggesting that the increased income from tungsten production may be associated with a decline in overall economic output, supporting the resource curse hypothesis. The study contributes to the growing body of the literature on the resource curse by investigating the unique case of tungsten and highlighting the importance of sustainable resource management, diversification, and effective governance in maximizing economic benefits while mitigating potential downsides.
Parity Doubling in Dense Baryonic Matter as an Emergent Phenomenon and Pseudo-Conformal Phase
Authors: Lee Hyun Kyu
Published: December 2024

The star matter composed of nucleons deep inside compact stars, such as neutron stars, is believed to be very dense, such that various types of new concepts and physical phenomena are naturally expected due to the nontrivial strong correlations between hadrons. The possibility of revealing the hidden scale symmetry in dense baryonic matter has been discussed recently, to uncover the pseudo-conformal phase in dense star matter. In the pseudo-conformal phase, the trace of the energy–momentum tensor becomes density-independent, and the speed of sound approaches the conformal velocity in scale symmetric matter. Interestingly, it is also observed that the effective nucleon mass becomes a density-independent finite quantity, which can be identified as the chiral invariant mass of the parity doublet model, indicating that the parity doubling is an emergent phenomenon. In this paper, we will discuss how parity-doubling symmetry emerges inside the core of a compact star as a consequence of the interplays between ω vector mesons and nucleons (or dilaton, χ, equivalently) and between the chiral symmetry and the scale symmetry.
Black Body-Inspired Chemically Oxidized Nanostructures with Varied Perforations: A New Frontier in Solar Desalination
Authors: Kaviti Ajay Kumar , Mohiuddin Shaik Afzal , Sikarwar Vineet Singh
Published: December 2024

Ideal black bodies absorb all electromagnetic energy without reflecting it. As it does not reflect or transmit light, it appears black when cold. Heated black bodies emit black body radiation, a temperature-dependent spectrum. This idea helps scientists and engineers comprehend heat radiation and design efficient solar desalination absorbers. This work uses the black body concept to create three non-contact nanostructured single-slope solar stills (NCNSSSs) with varied perforation diameters (2.4 mm, 3.2 mm, and 3.8 mm). The chemical oxidation of mirror-polished perforated stainless steel 304 sheets resulted in highly absorptive top surfaces with 90% absorptivity. The structures’ bottom surfaces were coated with a commercial high-emissivity coating to make them 85% emissive. The developed non-contact nanostructures absorbed maximum solar light and converted it into infrared radiation using a highly emissive bottom coating and a very absorptive top coating. Water, an excellent absorber of infrared (IR) radiation, readily absorbs the IR radiations and evaporates through the perforations, thus producing a desalination effect. Experiments were conducted parallelly in three NCNSSSs under the same weather conditions at three water depths. It was observed that non-contact nanostructure perforation diameters affected solar still performance. The NCNSSS-3 (3.8 mm) achieved a 9.89% and 13.47% higher productivity than the NCNSSS-2 (3.2 mm) and NCNSSS-1 (2.4 mm) at a 5 mm water depth. Additionally, fouling studies, expedited corrosion studies, and water quality assessments (TDS, salinity, fluoride, chlorides, nitrates, sodium) were performed. Water eminence examinations confirmed that the collected freshwater was bacteria-free and safe to drink.

Published: December 2024

Access to drinking water in Cuenca Alto Atoyac (CAA), serving over 3.5 million people, is challenged by contamination and inadequate disinfection processes. This study investigates the use of oxidation–reduction potential (ORP) as a tool to optimize disinfection in CAA’s water systems. The research was conducted in three stages: an initial pilot phase with 10 sampled sources, expanding to 14 supply sources in the experimental phase, followed by analyses defining optimal chlorine dosing and contact times across two distinct hydrogeological zones. Principal component analysis (PCA) identified key factors, explaining 53.52% of water quality variability, while ORP measurements revealed significant differences in water quality among sources, with “Ameca” and “Pozo #2 Santa María Atlihuetzían” representing the extremes. Adjusted chlorine doses and contact times were tailored to local conditions, achieving target ranges and ensuring improved microbial control. In the final stage, significant correlations were established between ORP levels, chlorine doses, and total coliform concentration, supporting the effectiveness of ORP in guiding disinfection processes. Overall, chlorine doses of 0.3–1.5 mg/L with contact times around 15 min yielded ORP values (594–687 mV) optimal for CAA water safety.

Kültür, bir toplumun yaşam tarzını belirleyip nesilden nesile aktarılan davranışlar, değerler, gelenekler, inançlar gibi unsurlardan oluşur. Bu unsurlar genel olarak toplumdan topluma sözlü olarak aktarılır. Sözlü kültür ve halk inanışları toplumların, tarihi, kimliği ve dünya görüşlerini şekillendiren önemli unsurlardır. Bu kavramlar, yazılı kaynaklardan ziyade nesilden nesile aktarılan bilgi ve gelenekleri içerir. Türk kültüründe sözlü kültürün önemi oldukça büyüktür. Özellikle göçebe yaşam süren eski Türk topluluklarında, yazılı kaynaklar çok fazla bulunmadığı için bilgi aktarımı ağırlıklı olarak sözlü kaynaklar aracılığıyla gerçekleşmiştir. Geleneği yansıtan inançların içinde ritüeller önemlidir. Birey ve toplum için önemli olan bu ritüeller kültürün şekillenmesinde belirleyici bir unsurdur ve insanoğlunun doğum, evlilik ve ölüm gibi önemli geçişlerinde gerçekleşir. Bu özel anlar toplumun gelenek ve inançlarına uygun olarak anılır. Toplumun sürekliliğini ve birlikteliğini pekiştiren geçiş dönemi ritüellerinden başlangıcı işaret eden doğumla ilgili inançlar, kültürün vazgeçilmez parçasını oluşturur. Bu dönemde sosyal ve biyolojik olarak değişim söz konusudur. Doğum ile ilgili olan geçiş dönemi ritüelleri, genelde bebeğin ve annenin korunup toplum tarafından kabul edilmesi ve yeni bir canlının dünyaya gelişini kutlayıp ona kimlik kazandırması bakımından önemlidir. Doğum öncesinden doğum sonrasına kadar çok sayıda gelenek, görenek ve inanç söz konusudur. İnanışlar farklı zamanlarda birtakım değişikliklere uğrasa da günümüzde devam etmektedir. Bu çalışma, insanoğlu için başlangıcın ifadesi olan doğum ile ilgili Türkiye’nin Doğu Anadolu Bölgesi’nde yer alan köklü bir tarihe sahip olan Erzincan’da geçmişte uygulanmış ve günümüzde hâlâ devam eden âdetleri, gelenekleri ve inançlarını derleyip inceleyerek belirlemeye yöneliktir.

İlin ritüel ve inançları hem bölgesel hem de genel anlamda Türk kültürüne ait önemli ipuçları vermesi bakımından da önemlidir. Bu ritüeller, bölgedeki toplumun değer yargılarını, sosyal yapısını, inançlarını anlamak için önemli veriler sunar. Geleneksel ritüellerin zamanla kaybolma ve unutulma riski karşısında çalışma ile kültürün korunması, yaşatılması ve gelecek nesillere aktarılması da amaçlar arasında yer almaktadır.
Evaluation of the synergistic effect of yeast and Chicory-inulin on rumen fermentation parameters and estimation of methane emission
Authors: Bett Kipkorir Josphat , Migwi Perminus K. , Ondiek James O.
Published: December 2024

Probiotics and prebiotics are feed additives that have been extensively utilised in animal nutrition for a considerable duration. However, only some studies have investigated their synergistic effects on rumen fermentation parameters and their role in minimizing methane emission. Therefore, this study examined the impact of combining chicory-inulin with yeast (Saccharomyces cerevisiae) on rumen fermentation parameters and methane emissions in weaned dairy goats. The feeds were formulated into eight diets and offered to 24 Saanen×Toggenburg crossbred weaned female dairy goats weighing 14±0.5 Kg in a Completely Randomized Design with a (4x2) factorial arrangement. The diets were Rhodes grass hay and chicory supplementation at four levels: 0, 10, 20, 20, and 30% as the main effects and with (+) and without yeast (-) yeast as interaction levels. The findings indicated that the inclusion of yeast and Chicory had a significant effect (p<0.05) on rumen pH, ammonia nitrogen concentrations, production of volatile fatty acids), and estimated methane emission. The highest pH was recorded in T1- with 7.27. It was followed closely by T1+ with 6.73. T1+ recorded the highest methane (39.67 mmol/L), while T4- had the lowest (32.42 mmol/L). This study concludes that Chicory-inulin has prebiotic properties by maintaining pH levels and affecting amounts of ammonia nitrogen. The lack of a significant interaction effect between yeast and Chicory in methane emission implies that their combined influence may not significantly affect methane emissions in the current study's experimental settings.

Contudo, o uso irracional motiva preocupações, uma vez que esses medicamentos podem ocasionar efeitos adversos graves quando utilizados de forma inadequada. Assim, a participação do farmacêutico é fundamental para promover a segurança e integralidade do cuidado. Objetivo: Descrever a importância da orientação farmacêutica no uso de medicamentos fitoterápicos para emagrecimento. Metodologia: Revisão integrativa da literatura, com buscas realizadas nas bases de dados Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), no Portal CAPES e na base PubMed entre os meses de fevereiro e junho de 2024, utilizando os seguintes descritores: Farmacêutico; Medicamento fitoterápico; Automedicação; Emagrecimento. Foram selecionados somente os estudos publicados nos idiomas português, inglês e espanhol, no período entre 2014 e 2024, com texto completo e pertinência temática. Quanto aos critérios de exclusão, não foram selecionados os relatos de caso, editoriais, anais de congressos e trabalhos com acesso pago. Resultados: A literatura analisada mostrou que os medicamentos fitoterápicos devem ser utilizados sob orientação profissional, haja vista os riscos de efeitos adversos ainda pouco conhecidos. O farmacêutico pode orientar os pacientes sobre o caráter coadjuvante desses medicamentos que, em conjunto com várias outras intervenções, pode proporcionar o emagrecimento saudável, advertindo dos riscos e complicações que podem ocorrer devido ao uso inadequado. As ações de educação em saúde, atenção farmacêutica, incentivo ao autocuidado e adoção de hábitos saudáveis são imprescindíveis no processo terapêutico do paciente com obesidade e o farmacêutico desempenha papel indispensável nesse contexto. Conclusão: A atuação do farmacêutico é essencial para o uso seguro e racional dos fitoterápicos, especialmente diante da crença comum de que produtos naturais não apresentam riscos à saúde. O acompanhamento farmacoterapêutico e as ações educativas também são essenciais para esclarecer sobre os riscos, objetivos terapêuticos e hábitos de vida que contribuem para o emagrecimento saudável.

Published: December 2024

Introdução: A violência doméstica contra crianças e adolescentes constitui um grave problema de saúde pública. No Brasil, é uma prática alarmante e frequente, evidenciando a família enquanto principal fonte de agressão. Essa experiência adversativa corrobora para um comprometimento desenvolvimental desses sujeitos, trazendo riscos tanto à saúde física quanto mental, sendo ainda mais prejudicial por se tratar de um grupo vulnerável, subordinados, muitas vezes, aos seus agressores. A pesquisa faz-se necessária, visto que nem sempre as vítimas conseguirão entender ou verbalizar, caso estejam em situações de vulnerabilidade à sua integridade física e psicológica, destacando-se a importância para que os profissionais de psicologia, e demais profissionais que trabalham com o público em questão, possam se capacitar e dar voz a esta população, elaborando medidas de prevenção e enfrentamento, quebrando esses ciclos de violência. Objetivo: O trabalho objetiva identificar, através dos estudos dispostos na literatura, os impactos no desenvolvimento de crianças e adolescentes vítimas de violência doméstica. Metodologia: Trata-se de uma revisão de literatura narrativa. Foram utilizadas as bases de dados eletrônicas SciELO e LILACS, a partir dos descritores: “violência doméstica”, “experiências adversas da infância”, “desenvolvimento Infantil”, “desenvolvimento do adolescente” e “saúde mental”. Os estudos em Português-BR, publicados nos últimos 10 anos, e de acesso gratuito, foram utilizados neste trabalho, enquanto os critérios de exclusão fixaram-se em publicações não brasileiras, com mais de 10 anos de publicação, e que não estavam disponíveis de forma gratuita. Resultados: Constata-se uma relação evidente entre a violência direcionada a crianças e adolescentes e os danos em seu desenvolvimento. Esses impactos ocasionam marcas profundas, que podem persistir até a vida adulta, resultando em consequências emocionais e comportamentais a longo prazo, como o surgimento de Transtornos Mentais Comuns. Considerações finais: A prática da violência doméstica contra crianças e adolescentes desempenha prejuízos significativos ao processo desenvolvimental desses sujeitos, que afeta não apenas a saúde física, mas também o bem-estar emocional, segundo apontam os estudos analisados neste trabalho. Destaca-se que, embora a família tenha a função protetiva e de cuidado dentro do lar, denota-se que grande parte da violência vivenciada pelo público infanto-juvenil ocorre dentro do ambiente familiar.

Published: December 2024

Introdução: O presente trabalho tem como tema a correlação entre psicopatia e comportamento criminoso, a partir de uma perspectiva comportamental, com foco na análise dos fatores ambientais e contextuais que influenciam a manifestação de comportamentos violentos em indivíduos diagnosticados com transtorno de psicopatia. Faz-se necessário apropriar-se com essa temática, abordar sobre a psicopatia e se possui uma interligação com os crimes cometidos por indivíduos que possuem esse diagnóstico. Objetivo: O objetivo da pesquisa é analisar indivíduos com o transtorno de psicopatia e de que modo isso influencia na sociedade, tendo como enfoque o caso “Canibais de Garanhuns”. Pretende-se, portanto, trazer as questões da literatura sobre o diagnóstico da psicopatia, refletir sobre os fatores e riscos associados à psicopatia em crimes violentos cometidos por seriais killers e avaliar retrospectivamente o caso "Canibais de Garanhuns", para compreender os fatores ambientais em torno do episódio. Metodologia: O método consiste em uma revisão de literatura, incluindo pesquisas bibliográficas e documentais e estudos de caso retrospectivos. Com base nas informações obtidas neste estudo, esta revisão baseia-se em diversos processos de investigação, que utilizam procedimentos especificamente concebidos para integrar o conhecimento científico na análise da relação entre psicopatia e comportamento criminoso, numa perspectiva comportamental. Resultados e discussão: A psicopatia foi definida, segundo os critérios da DSM-V TR, como um transtorno de personalidade antissocial. No entanto, é válido ressaltar que nem todo psicopata tem propensão a cometer crimes. À medida que um psicopata pratica assassinato de uma série de pessoas, esses indivíduos são considerados seriais killers, como é o caso do trio Jorge, Bruna e Isabel, moradores da cidade de Garanhuns, no estado de Pernambuco, que, no ano de 2012, ficaram conhecidos pelos níveis de crueldade impostos às suas vítimas. Conclusão: Por meio dessa pesquisa, foi possível obter uma compreensão mais ampla acerca do diagnóstico da Psicopatia e a influência na sociedade, destacando-se a importância de reconhecer tal transtorno e de diferenciar os traços psicopáticos daqueles que se tornam seriais killers.

Published: December 2024

Introduction: In the Republic of Belarus, no hygienic standards or methods of control in the workplace air have been developed for the group of modern amide local anesthetics, including articaine hydrochloride.
Objectives: To study the specific toxic effect of the pharmaceutical substance articaine hydrochloride on the respiratory system, to establish limiting indicators and threshold concentrations for chronic inhalation exposure for subsequent justification of the safe level of the substance in the workplace air of a pharmaceutical facility.
Materials and methods: Experimental studies were carried out on 36 outbred albino rats intranasally exposed to various concentrations (2, 10 and 50 mg/m3) of the pharmaceutical substance during 4 months. At the end of the experiment, we collected bronchoalveolar lavage fluid and tested it for cytokine concentrations and cellular structure. The trachea, bronchi and lungs were isolated from euthanized animals for pathomorphological studies. Statistical data processing was performed using parametric and nonparametric tests in Statistica 13 software. Differences between groups were considered significant at p < 0.05.
Results: The specific toxic effect of the pharmaceutical substance on the bronchopulmonary system at different levels (2-10-50 mg/m3) of inhalation exposure to articaine hydrochloride was manifested by the maximum development of pathomorphological structural changes at the highest concentration of 50 mg/m3, such as a statistical increase in the thickness of the interalveolar septa of the lungs by 1.85 times, the appearance of pronounced perivascular and peribronchial infiltration in the lungs in more than half of the rats. Changes in the composition of bronchoalveolar lavage were characterized by a significant increase in the cellular inflammatory component and transformation of the cytokine profile. At the exposure of 50 mg/m3, an increase in the content of lymphocytes and neutrophils was noted by 6.09 and 3.4 times, respectively, the appearance of plasma cells and an increase in the concentration of IL-1 and IL-6 by 2.0 and 3.2 times.
Conclusions: The dose-dependent morphological, cytological, and functional changes in the respiratory organs and lavage characterize the exposure concentration of 2 mg/m3 as practically ineffective, 10 mg/m3 as threshold, and 50 mg/m3 as effective in terms of the toxic effects under study.
