Our goal is to collect rainfall data per 250 - 400 ha. Upon selection of a rainfall gauge, we realized that the cost of using, for example, a tipping bucket-type rain gauge would be too expensive and thus searched for an alternative method. We selected an all-in-one commercially available weather station;hereafter, referred to as a Personal Weather Station (PWS) that is both wireless and solar powered. Our objective was to evaluate average measurements of rainfall obtained with the PWS and to compare these to measurements obtained with an automatic weather station (AWS). For this purpose, we installed four PWS deployed within 20 m of the Plant Stress and Water Conservation Meteorological Tower that was used as our AWS, located at USDA-ARS Cropping Systems Research Laboratory, Lubbock, TX. In addition, we measured and compared hourly average values of short-wave irradiance (R<sub>g</sub>), air temperature (T<sub>air</sub>) and relative humidity (RH), and wind speed (WS), and calculated values of dewpoint temperature (T<sub>dew</sub>). This comparison was done over a 242-day period (1 October 2022-31 May 2023) and results indicated that there was no statistical difference in measurements of rainfall between the PWS and AWS. Hourly average values of R<sub>g</sub> measured with the PWS and AWS agreed on clear days, but PWS measurements were higher on cloudy days. There was no statistical difference between PWS and AWS hourly average measurements of T<sub>air</sub>, RH, and calculated T<sub>dew</sub>. Hourly average measurements of R<sub>g</sub> and WS were more variable. We concluded that the PWS we selected will provide adequate values of rainfall and other weather variables to meet our goal of evaluating dryland cotton lint yield per unit rainfall. 展开更多

The House Martin(Delichon urbicum)is a common farmland bird species in the European landscape,yet its population numbers are currently in decline.However,it is not yet sufficiently explained why this long-term decline occurs.To fill this gap in our knowledge,we investigated how land cover composition affects the abundance of House Martins on the landscape scale by using nationwide citizen science data.Utilizing a generalised linear mixed-effect model(GLMM),we evaluated 12,094 records from the Czech Republic spanning 2009-2017.Our analysis underscores the significance of land cover type in shaping House Martin abundance.More specifically,our results indicate that within agricultural land covers“naturally managed arable lands”exhibited significant positive effect,while forests,orchards,and vineyards were deemed less favourable for House Martin populations.Within urban land covers,we found a clear distinction in the impact on House Martin populations,with a positive effect observed in urban infrastructure,development areas,and post-industrial sites(i.e.,UrbanAreas),while an indifferent impact was noted within urban green spaces and landscaped areas(i.e.,GreenUrban).Notably,our findings suggest that the simple spatial,age,and species structure typical of forests in Europe,and similarly,the uniform structure of parks and gardens,may be responsible for the decline in the abundance of the House Martin.We advocate for the preservation or enhancement of urban greenery,expansion of natural vegetation in rural areas and adoption of ecological management practices in orchards and vineyards to mitigate further declines in House Martin populations. 展开更多

Contemporary liberal theory on moral rights argues that moral rights associated with personal liberty constitute a strong constraint on the boundaries of state power.Therefore,the core issue of the penalty justification is not the purpose of the penalty,but the reason for the penalty to refrain from infringing on the moral rights of individuals.In order to justify the penal system,scholars have explored solutions such as limiting the content of rights,waiving rights,and finally rights forfeiture.However,the concept of rights forfeiture cannot be reasonably integrated into the framework of the liberal theory of moral rights.The failure of these attempts stems from the patchwork understanding of rights presupposed by the liberal theory of moral rights.There is another systematic way of understanding rights that offers a better justification.Individual rights are not an independent non-derivative moral justification,and both individual rights and the penal power of the state are only part of a specific(realistic or ideal)system of rules that collectively serve certain values.The real question of penalty justification is not why the punishment does not infringe on the moral rights of individuals,but whether the overall institutional arrangements,including the penal system,are justifiable for all citizens,including the punished. 展开更多

In contemporary society,film,as a significant form of cultural expression,bears profound ideological connotations and cultural significance.Religious films,as a distinct genre,serve as crucial avenues for humanity to explore and contemplate religious beliefs,moral concepts,and the essence of existence.Plato’s philosophy,as a significant pillar of Western thought,exerted profound influence on the conception and depiction of religious films.This thesis aims to examine Plato’s philosophical impact on religious cinema,elucidating its significance and value via comprehensive analysis of his ideas and their manifestation in religious films.Platonic ideas transcend the realm of emotions,inciting moral conflicts and dilemmas in religious films,thereby probing the dynamics between good and evil,justice and injustice.Plato’s political concepts offer profound sociopolitical reflections within religious films,stimulating discourse on matters like authority,governance,and liberty.Additionally,it catalyzed inquiries into aesthetics and emotions.Plato’s appreciation and pursuit of beauty resonate extensively in religious films,guiding viewers into a transcendent aesthetic realm through depictions of beauty and emotion.This holds immense theoretical and practical significance in deepening individuals’comprehension of Plato’s philosophy,fostering cultural exchange and discourse,and augmenting the artistic merit and societal impact of religious films. 展开更多

This study elucidates the pivotal role of citizen science-BioBlitz methodologies for rapid assessment of the macro-invertebrate taxa within the threatened River Rwizi of South-western Uganda. Utilizing a comprehensive mixed-methods approach, the investigation focused on six distinct river segments to demonstrate the efficacy of participatory citizen science-BioBlitz approaches conducted by experts, students and community volunteers. BioBlitz events included rigorous macro-invertebrate sampling at each of the selected sites along River Rwizi on nine occasions, incorporating collaborative taxonomic identification procedures involving experts, students, and the local community. Analyzing pollution concerns, diversity metrics, and community narratives yielded insights into river health and socio-ecological dynamics. A total of 43 macro-invertebrate families across 17 orders were documented with class Insecta dominating. Participants in BioBlitz events expressed predominantly positive sentiments, emphasizing satisfaction, education, and heightened awareness, besides negative sentiments rooted in historical mistrust. Intriguingly, the study unveiled an unforeseen trend in macro-invertebrate taxa richness, rising from upstream to urban sprawl and diminishing at peri-urban downstream sites. The study underscores the potential of citizen science-BioBlitz methodologies in advancing community science education and unraveling the intricate dynamics of threatened river ecosystems. The insights offered are invaluable for policymakers and conservationists seeking effective strategies to address challenges in the River Rwizi and comparable ecosystems. . 展开更多

The loss of bird species diversity is a crucial problem in the European agricultural landscape.Change in the area coverage of major land cover types has been mentioned as one of the main factors responsible for bird biodiversity impoverishment.In this study,we focused on the impact of landscape matrix characteristics on bird species richness and on Faith’s phylogenetic diversity index on a spatial scale of 1000-m radius around the measured occurrence points.We investigated how land cover composition affects bird diversity on the landscape scale using nationwide citizen science data.In total,168,739 records of bird occurrence in the South Moravian Region of the Czech Republic during growing season from 2009 to 2019 were evaluated.We found that the presence of water bodies and wetlands significantly corresponded to the areas of highest bird species richness.We also revealed that the presence of forests(~60%of the forest in the Czech Republic is occupied by commercial forests),urban areas and arable land were negatively associated with bird species richness and phylogenetic diversity.Forests(both coniferous and deciduous)and urban habitats were found to have a tendency to host a clustered phylogenetic community structure in comparison with wetland and arable land.A strong negative association between forest proportion and bird diversity led us to conclude that the expansion of the forest(with simple species composition,horizontal and vertical structure)could be one of the critical drivers of the decline of bird species diversity in the European agricultural landscape.On the other hand,our results also pointed out that small woody features(i.e.,woodlots)and scattered woodland shrub vegetation were one of the main landscape characteristics supporting a bird diversity in rural landscape.This is in concordance with other studies which mention these landscape structures as important elements for nesting and foraging of farmland birds.We thus recommend to maintain and restore scattered trees or woodlots with complex structure in agricultural landscape. 展开更多

The Adventures of Huckleberry Finn is honored as the most typical novel of American literature after the Civil War. This story unveils the hypocrisy of religion and scoffs at the conventional social principle. Affected by the deep-rooted racial discrimination, Huck pays little respect to the black slaves as other white people do at first. After embarking on the raft with Jim together, he has got the chance to know more about what the black slave truly is. He never stops struggling inside, and eventually Jim's kindness and loyalty helps Huck to waken humanity in his heart and defeat his moral conflict. Therefore through the deepened analysis of the plot and the author, the reasons for the change of Huck's morality can boil down to social conventions, Huck's complicated character, and moreover the democratic ideal of Twain. 展开更多
