Weak influence of natural vegetation in urban green spaces compared to agricultural ecosystems on House Martin populations:Insights from nationwide citizen science data in the Czech Republic

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.

Van Earthquake’s Effects on Mud-Brick Houses in Van and the Last Survived Buildings

The city of Van is located to the Eastern Region of Turkey and has experienced two large earthquakes recently. Van earthquakes have caused big damages and demolitions in the city center, districts and in villages. As a result of precautions works have been realized to remove its effects shortly. However, it can be seen that the either urban or rural areas of the city carry the earthquake’s traces. Damages that the eartquake left on the buildings formed the most apparent and standing ones of the traces. Mud-brick buildings are the primary of those damaged buildings both in the centre of Van and in villages. Especially roofs’ collapsing and then walls’ demolition for mud-brick houses which were abandoned, and therefore were not maintained properly for a long time, are quite familiar situations after the earthquake. However, inhabited and maintained houses have been survived sturdily by contrast of other houses with modern materials and they helpt life to continue after the earthquake. In this study, mud-brick houses which were survived after earthquakes in Van and in the villages will be discussed. Reasons for demolition of those demolished and the qualities of those surviving ones will be scrutinized. It is going to be discussed how the mud-brick material which is distinguishing and struggling to gain it deserves as an ecological material today to resist against natural disasters sturdily when it is applied in decent way in scope with examples in the city of Van. Purpose of this study is to document right and wrong usage of the mud-brick materials with examples.

The Economic Demands on the Method of Founding a Passive Brick House on Foamed Glass Granulate

The cost of acquisition of a passive house is a little higher than that of a conventional house.Proper design of a passive house should include not only thermal protection and stability of the construction,but it must also take into account the price demands on each of the proposed structures and solution of details.The paper deals with the financial comparison of the traditional method of a foundation on the foundation strips of plain concrete and the modern method of founding a passive house as brick construction on the reinforced concrete slab base with a compact subsoil layer of thermal insulation in the form of granules of foamed glass.

Peak Particle Velocity Predicting Equation Associated with the Propagation of Vibrations Induced by Blasting in a Mine and Impacts on the Physical Degradation of Houses: The Case of the Yaramoko Mine, Bagassi, Burkina Faso

This study utilizes empirical equations to describe the propagation of vibrations induced by blasting, with the goal of predicting the attenuation of Peak Particle Velocity (PPV) at the Yaramoko mine in Bagassi, Burkina Faso, a site characterized by granitoid rock. Four empirical PPV prediction equations were employed, so-called Duvall & Fogelson (or the United States Bureau of Mines “USBM”), Langefors and Kihlstrom, Ambressys-Hendron, and the Bureau of Indian Standard. The constant parameters for each of these equations, referred to as site constants, were derived from linear regression curves. The results show that the site constants k, a, and b of 4762, 0.869, and 1.737, respectively, derived from the general prediction equation by Davies, PPV = kQaD−b, based on Duvall & Fogelson, are in good agreement with values of 4690, 0.9, and 1.69, respectively, for similar rock types in Spain. Regarding the impacts of blasting on houses, the findings indicate that houses built from laterite-block bricks in the village of Bagassi are the most vulnerable to vibration waves, followed by those constructed with cinder-block bricks. In contrast, houses made of banco bricks are the most resilient. Additionally, it was determined that during blasting operations, adjusting the blasting parameters to ensure the PPV does not exceed 2 mm/s at the level of nearby dwellings can minimize the appearance of cracks in houses.

Confucian Moralizing Functions of Vernacular Houses:A Case Study of Vernacular Houses of Dongting East Mountain and West Mountain

Confucian ethics, idea and behavior criterion were embodied in "everything" of life, especially in the building as an important tool for moralizing. Taking a case study on vernacular houses of Dongting East Mountain and West Mountain, this paper reveals the "moderate", "etiquette" and "benevolence" as moral contents in the building's layout, form, space, decoration and so on. The moralizing reflects a subtle way of guidance, as well as diversified and systematic characteristics. Vernacular houses deeply mingled with daily life, had unique influence as physical environment, thus realizing the implementation and manifestation of Confucian moralizing ideas that have been converted to folk customs. In sum, the Confucian moralizing function carried by vernacular houses is the product of institutions and rules, and it is also the manifestation of conscious inheritance of cultural identity.

Evaluate the Value of Houses around the Garbage Transfer Station Based on CVM

In recent years,with the rapid development of China’s economy,a large number of people have flocked to the cities,which also brings more residential waste.The increased waste overloads transfer stations located near residential areas,and the continuous noise and odour affect the daily lives of nearby residents.In addition,the neighbourhood avoidance facilities represented by the waste transfer stations also reduce the value of the surrounding residents’houses.Therefore,using the conditional value method and the Tobit and Double Hurder econometric models,this article investigates the implicit value of the Fuli Resort neighbourhood under the influence of the waste transfer station through a questionnaire survey on the willingness of the residents to accept the compensation,which can be regarded as the“aversion value”of the neighbourhood due to the aversion to the waste transfer station and analyses the impact of the aversion value of the neighbourhood.aversion value and analyses the impact on residents’willingness to accept compensation.The study found that the residents’willingness to accept compensation near the waste transfer station is 511.94 RMB/person/month,and the implicit value of the Fuli Resort neighbourhood under the influence of the waste transfer station in Qinhuai District,Nanjing,Jiangsu Province,China,is 147,950 RMB.The study found that residents are most interested in having the government rectify the waste transfer station and set sanitary standards and work norms.

Investigation on the Concurrent-Business Behavior of Peasant Households during the Planting Structure Adjustment in Karst Mountainous Area

Based on the survey data of 150 peasant households in typical Karst mountainous area in the year 2009, causations, characteristics and influence factors of the concurrent-business behavior of peasant households during planting structure adjustment are analyzed. Result shows that there is significant positive correlation between the concurrent-business income and the household income of farmers. And the concurrent-business behavior has the tendency to be popular among the young farmers with the characteristics of relative concentration, strong will of farmers and the significant impact of education degree on the concurrent-business income. Information, capital, skill, and market awareness are the main factors affecting the concurrent-business behavior of peasant households. Countermeasures to optimize the concurrent-business behavior of peasant households are put forward, such as strengthening the skills training for farmers to improve the cultural quality of peasant households, establishing modern rural financial service system to offer capital support for the development of peasant households, setting up information base of rural labor force to provide more information and channels for the concurrent-business behavior of peasant households, and enhancing the cultivation of farmers' market awareness to improve their ability to adapt to market economy.
