This allows improved pregnancy results and the avoidance of unintended births. Teenagers’ views on using contraceptives are influenced by the information available at their disposal. The study assessed the influential factors affecting the utilization of modern contraceptives among the youth in Akuse in the Eastern Region of Ghana. Methods: The data for the study were gathered from 378 consented youth aged 15 - 24 years using a quantitative cross-sectional study design and a well-structured questionnaire. Person’s Chi-Square test was adopted to measure the association between the outcome variable and selected independent variables. Logistic regression models were utilized to measure the odds of the factors influencing modern contraceptive use among the respondents. Results: The results of the study suggested a high knowledge level of contraceptives;however, the prevalence of utilization was low. The level of education and age were factors found to influence the uptake of contraceptives. A bivariate analysis to examine the association between selected socio-demographic variables revealed that educational level (p = 0.044), religious affiliation (p = 0.002), and ethnicity (p = 0.016) were statistically associated with modern contraceptive use among the respondents. All other tested demographic variables including the age groups, gender, marital status, and residential status proved otherwise at the observed p-values greater than the 0.05 threshold. Respondents who indicated staying with partners were 6.79 times more likely to use contraceptives compared to their counterparts staying with a parent, after controlling for all other covariates. Conclusions: Based on the findings of this study, it was concluded that high contraceptive knowledge influences the choice of contraceptive preferred by the youth, and contraceptive use is also influenced by the advancement in age and educational level of the youth. It is however recommended that parents, guidance, and teachers be entreated to offer relevant and timely sexual information or education as these will most likely improve the uptake of modern contraceptives among the targeted population.展开更多

Conservation agriculture (CA) based management approaches have proven to enhance C sequestration and reverse the loss of soil-organic-carbon (SOC), which further enhances soil fertility. Different fractions of SOC pools react to the alterations in management practices and indicate changes in SOC dynamics as compared to total C in the soil. Higher SOC levels in soil have been observed in case of reduced/no-till (NT) practices than conventional tillage (CT). However, between CT and zero tillage/NT, total SOC stocks diminished with an increase in soil depth, which demonstrated that the benefits of SOC are more pronounced in the topsoil under NT. Soil aggregation provides physical protection to C associated with different-sized particles, thus, the improvement in soil aggregation through CA is an effective way to mitigate soil C loss. Along with less soil disturbance, residual management, suitable crop rotation, rational application of manures and fertilizers, and integrated nutrient management have been found to be effective in not only improving soil C stock but also enhancing the soil health and productivity. Thus, CA can be considered as a potential method in the build-up of SOC of soil in rice-wheat system.展开更多

文摘Understanding the distribution,dispersal,and correlation of modern pollen with vegetation in mountainous regions is essential for establishing accurate modern analogs for fossil pollen records.This study,conducted in Leigong Mountain on the YunnanGuizhou Plateau of southwestern China,involved the collection of 35 surface soil samples from diverse vegetation communities along an elevational gradient ranging from 1210 to 1875 meters.The results reveal a close correspondence between modern pollen assemblages and vegetation zones.Principal Component Analysis(PCA)results indicate that pollen assemblages can effectively distinguish between subtropical montane evergreen broad-leaved forest(SEBF)and subtropical montane deciduous broadleaved forest(SDBF).However,both SEBF and SDBF show significant overlap with subtropical montane evergreen-deciduous broad-leaved mixed forest(SEMF).Detrended Correspondence Analysis(DCA)results clearly distinguish the three vegetation zones,and the first axis of DCA shows a significant positive correlation with elevation(p<0.01,R=0.48).Discriminant Analysis(DA)successfully assigns 94.4%of the modern pollen samples to their respective vegetation zones.Pollen taxa such as Impatiens,Astertype,and Rosaceae exhibit significant indicative capabilities for the SEBF zone,effectively distinguishing this vegetation zone from others.Pinus and Alnus display overrepresentation in the Leigong Mountain region,while Quercus(D,deciduous-type)and Poaceae exhibit high representation in the SEBF zone.In the SEBF zone,both pollen diversity and richness are the lowest.Our study reveals the complex relationship between the richness and diversity of pollen and vegetation.The diversity and richness of tree and shrub pollen are found to be lower than those of the corresponding plants.The pollen-vegetation relationship elucidated in this study serves as a critical reference for reconstructing ancient environments from fossil pollen retrieved in this region.
文摘Urban agriculture is gaining recognition for its potential contributions to environmental resilience and climate change adaptation,providing advantages such as urban greening,reduced heat island effects,and decreased air pollution.Moreover,it indirectly supports communities during weather events and natural disasters,ensuring food security and fostering community cohesion.However,concerns about planetary health risks persist in highly urbanized and climate-affected areas.Employing electronic databases such as Web of Science and PubMed and adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines,we identified 55 relevant papers to comprehend the planetary health risks associated with urban agriculture,The literature review identified five distinct health risks related to urban agriculture:(1)trace metal risks in urban farms;(2)health risks associated with wastewater irrigation;(3)zoonotic risks;(4)other health risks;and(5)social and economic risks.The study highlights that urban agriculture,while emphasizing environmental benefits,particularly raises concerns about trace metal bioaccumulation in soil and vegetables,posing health risks for populations.Other well studied risks included wastewater irrigation and backyard livestock farming.The main limitations in the available literature were in studying infectious diseases and antibiotic resistance associated with urban agriculture.
文摘Ploughing and fertilization practices in rice-wheat system have deteriorated the soil carbon (C) pools. Conservation agriculture (CA) based management approaches have proven to enhance C sequestration and reverse the loss of soil-organic-carbon (SOC), which further enhances soil fertility. Different fractions of SOC pools react to the alterations in management practices and indicate changes in SOC dynamics as compared to total C in the soil. Higher SOC levels in soil have been observed in case of reduced/no-till (NT) practices than conventional tillage (CT). However, between CT and zero tillage/NT, total SOC stocks diminished with an increase in soil depth, which demonstrated that the benefits of SOC are more pronounced in the topsoil under NT. Soil aggregation provides physical protection to C associated with different-sized particles, thus, the improvement in soil aggregation through CA is an effective way to mitigate soil C loss. Along with less soil disturbance, residual management, suitable crop rotation, rational application of manures and fertilizers, and integrated nutrient management have been found to be effective in not only improving soil C stock but also enhancing the soil health and productivity. Thus, CA can be considered as a potential method in the build-up of SOC of soil in rice-wheat system.

文摘Modernization,as a specific stage in the historical development of human society,possesses a multi-layered composite structure,with each layer playing both a promoting and inhibiting role in human development and dignity simultaneously.Chinese modernization is a strategic choice made based on lessons learned from various experiences of modernization processes in other countries,reflecting judgments on the benefits and choices on the values of human development and dignity in modernization.It values the promotion of the free and well-rounded development of all individuals as its standard,demanding the full realization of the positive effects of modernization on human development and the overcoming of its negative effects.Human rights,aiming to promote the free and well-rounded development of every person as the ultimate value goal,are not only an intrinsic structural element of the modernization stage but also a social normative tool that restrains the direction of modernization development,aligning closely with the values pursued by Chinese modernization.Chinese modernization poses dual requirements for human rights protection:on the one hand,it demands the affirmation and promotion of the positive effects of modernization on human development and dignity through human rights standards,and on the other hand,it requires the prevention and mitigation of the negative effects of modernization on human development and dignity through human rights standards.There exists a certain tension between these two dimensions,necessitating an appropriate balance and thereby presenting corresponding requirements for China’s approach to human rights protection.

文摘The paper is based on literature search,introducing and analyzing the book publishing situation of modern Peking University Library from the perspective of the publisher being Peking University Library and its predecessor.It is pointed out that the majority of the book printing methods published by the modern Peking University Library are lead printing,and among the types of Chinese library classification,catalogue of library collections is the most common.
文摘With the continued increase in the number of people that are food insecure globally, which could be increasing because of the ongoing Ukraine-Russia war, leading to reduction in international agribusinesses, coupled with drastic climate change exacerbating the problem of food insecurity, there is a constant need to come up with innovative approaches to solve this global issue. In this article, we articulated how precision agriculture can be a tool for ensuring food security in the United States. This study aims to reiterate the significance of precision agriculture in solving global food insecurity.

文摘Many modern Chinese libraries have established distribution agencies in other cities to distribute books published or sold on consignment.Huating Bookstore,which was once the Shanghai General Distribution Office of Zhejiang Library in modern times,is one of them.On the basis of a brief description of modern Zhejiang Library and its book publishing,as well as the overview of Huating Bookstore,the paper introduces and analyzes the ZPL Publishing Book Catalogue sent by Huating Bookstore,and the ZPL publishing and selling consignment books issued by Huating Bookstore.It points out that Huating Bookstore is a bridge between the ZPL located in Hangzhou and various retail ZPL publishing bookstores in Shanghai.Their production and sales relationship is a mutually beneficial one.
文摘Although it is well known that the ancestors of modern humans and Neanderthals admixed,the effects of gene flow on the Neanderthal genome are not well understood.We develop methods to estimate the amount of human-introgressed sequences in Neanderthals and apply it to whole-genome sequence data from 2000 modern humans and three Neanderthals.
文摘Understanding modern poetry is a big problem for average readers because of all kinds of rhetorical devices filled with them,especially metaphors,which are hard for the readers to understand clearly.Thus,grasping metaphors would provide a possible solution to enhance the understanding of modern poetry.Based on the motivation to better understand modern poetry,the paper explores the 11 mechanisms of metaphors in modern poetry with examples in detail,i.e.,blending,mapping,frame shifting,image schema,conceptual integration,contextual grounding,inter-subjectivity,embodied cognition,recursiveness,juxtaposition,shape-moulding,by borrowing some concepts from Cognitive Linguistics,literary studies,and Rhetorics,which can be adopted as means and methods to understand modern poems.
文摘In the context of the information age,modern electronic technology has gradually penetrated into every aspect of our lives,and the field of education is no exception.Especially in English reading teaching,the application of electronic technology has provided unprecedented convenience and possibilities for teachers and students.However,just as every coin has two sides,modern electronic technology has also brought a series of challenges.Some students may overly rely on electronic devices for reading and overlook traditional paper-based reading methods,leading to a decline in reading comprehension ability.In addition,prolonged use of electronic devices can also have a negative impact on students’eyesight.Therefore,when using electronic technology for reading teaching,teachers need to pay attention to guiding students reasonably,balancing the use of electronic devices and traditional reading methods,and protecting students’vision and reading comprehension abilities.This article aims to explore the promotion and challenges of modern electronic technology in English reading teaching.
文摘Piano originated in Western countries,so a large number of Western cultural elements are used in piano art creation,mainly to present Western humanistic thoughts and spiritual cultural cores to the audience.In recent years,with the modernization of piano art and culture in China,many Chinese listeners have begun to demand more ethnic and folk piano pieces with Chinese characteristics.In order to meet the audience’s pursuit of modern Chinese piano art,more and more creators are integrating ethnic music elements into modern piano art creation.This article explores the integration significance of ethnic music elements in modern piano art creation and the current situation of Chinese modern piano art creation,and finds that ethnic music elements have positive help in enhancing the novelty,ethnic characteristics,and timeliness of piano art creation.Based on this,this article proposes several strategies for integrating traditional ethnic music elements into modern piano art creation,including adapting traditional ethnic music elements,creating pentatonic tunes,and modifying work titles.The aim is to provide references and inspiration for the development of Chinese piano art creation and culture.
