The urbanization has always been accompanied by national economic development and social progress, relocation and development of rural areas have become a social issue for a certain time. Therefore, it is imperative to explore a series of concrete, well-timed and practical measures for settling rural population, figure out proper modes, materials and methods for rural residence planning and construction under the new conditions, and provide relevant operation and theoretical support. Problems in mountainous rural areas of China were proposed as great population but limited land resources, backward construction techniques, and residences not valuing low carbon or environment protection. In view of these problems, construction techniques suitable for actual conditions of rural areas were explored, energy-saving building materials combined, the style of "dragon sucking water" for mountainous rural areas was proposed, design advantages and details of this architectural model were analyzed.展开更多

It is the main platform used by them to publish press releases and, especially, to reach out to their fans. Given the pervasiveness of celebrities on the site, people with related interests may be especially likely to start using the service due to the perception of direct access to a famous person. As for the celebrities, it is a way of being close to the public and giving them an insight in to the life of a celebrity. Although most celebrity Twitter accounts are only used for promotion purposes, many celebrities use their personal accounts for the purpose of communicating with their fans, friends and other celebrities. These celebrities tweet personal photos and share their inner thoughts for various reasons and to different audiences. Thus in this study I ask: What are celebrity speech patterns on Twitter? Are they talking mostly to fans, and if not, who are they talking to? How are they talking to these different audiences? I address these questions by analyzing the tweets publicly available on four active celebrities’ Twitter timelines. The findings support that these celebrities indeed address different audiences on Twitter, including fans, friends, family and other celebrities. The findings further reveal that celebrities tend to communicate using different speech acts when talking to these different audiences. In light of this evidence, I attempt to highlight patterns that may be relevant with regards to the celebrities’ gender.展开更多

However, all these benefits sometimes are not enough to convince a homeowner to pay the incremental cost associated with the energy-efficiency measure. The objective of this work is to develop a methodology for the economic evaluation of residential energy-efficiency measures that can simplify the economic analysis for the homeowner while taking into consideration all factors associated with the purchase, ownership, and selling of the house with the energy-efficiency measure. The methodology accounts for direct and indirect economic parameters associated to an energy-efficiency measure;direct parameters such as the mortgage interest and fuel price escalation rate, and indirect parameters such as savings account interest and marginal income tax rate. The methodology also considers different cases based on the service life of the energy-efficiency measure and loss of efficiency through a derating factor. To estimate the market value, the methodology uses the future energy cost savings instead of the cost of the EEM. Results from the methodology offer to homeowner annual net savings and net assets. The annual net savings gives the homeowner a measure of the annual positive cash flow that can be obtained from an energy-efficiency project;but more important, the net assets offer a measure of the added net wealth. To simplify and increase the use of the methodology by homeowners, the methodology has been implemented in an Excel tool that can be downloaded from the TxAIRE’s website.展开更多

Objective: To identify variations in wellness and inclusivity website depictions across CREOG districts over the past two years. Methods: This is a cross-sectional analysis of the websites of ACGME-accredited OB/GYN residency programs across the United States between April 2022 and April 2023. The assessment was based on a compilation of 22 attributes devised and piloted by 49 medical students. A racially, geographically, and gender-diverse cohort of 11 students performed data collection. Results: A total of 560 websites were analyzed over two years. Wellness efforts remained unchanged in both years (website content, dedicated support personnel, and group activities). In 2023, a reduction in referencing of wellness (22%) and inclusivity (30%) occurred in leadership messaging. However, a 7% increase in the use of inclusive pronouns was noted. A reduction in gender diversity was identified (9% in faculty, 5% in residents), with programs favoring female-only teams. Similarly, a 7% reduction in the number of underrepresented in medicine faculty and residents was noted. A 15% reduction was noted in curricula referencing inclusivity in their mission statement and inclusivity focused research. Conclusions: This study suggests the variations across websites relative to inclusivity and wellness over the past two years. Updated websites may provide an accurate reflection of the offerings of programs and their investment in wellness and inclusivity across the nation.展开更多

文摘Clean-energy substitution technology for existing residential buildings in cities is an inevitable choice for sustainable development and low-carbon ecological city construction.In this paper,the current status of energy-saving renovation and renewable-energy applications for existing residential buildings in various cities in China was summarized by using statistical methods.The geographical distribution of clean-energy power generation in primary energy production in China was explored in depth.According to different climatic divisions for existing urban residences,clean-energy production and consumption were analyzed and predicted based on the STIRPAT model.The results show that the energy consumption of urban residential buildings in 2016 increased by 43.6%compared with 2009,and the percentage of clean energy also increased from 7.9%to 13.4%.Different climatic regions have different advantages regarding clean energy:nuclear power generation leads in the region that experiences hot summers and warm winters,whereas wind and solar power generation lead in the cold and severely cold regions.The present results provide basic data support for the planning and implementation of clean-energy upgrading and transformation systems in existing urban residences in China.
文摘As the staying duration of the refugees who come from Syria to Gaziantep prolonged,the need for residence together with the need for shelter came up.This city,which received internal migration previously and which already had an intense squatting problem,increased its housing demand further with the fast migration of Syrian refugees to the city and unfortunately had to open up even the unhealthy,unused structures to be used.This study aims to identify the lifestyle,family structure,economic condition,type of housing,and places that refugees use both in Syria and in Gaziantep in order to solve the housing problem more optimally,to compare and evaluate the condition and use of the cultural and social areas available around residences,and to shed light on the housing projects which will be built later.As a result,the size of the residences which Syrians use decreased.If new structures which will be preferred also by Syrians will be built,the green areas and social facilities of these structures should be structured.As apartment type structures are preferred more,more number of rooms and the separate design of the bathroom and WC should also be organized.
文摘BACKGROUND The coronavirus disease 2019 pandemic unleashed a flood of untrustworthy information on social media platforms,resulting in the unfortunate consequence of expert scientists'opinions getting lost amidst the chaotic sea of misinformation.The question of how much influence these esteemed scientists hold on social media platforms remains elusive.To address this scientific quandary,we sought to explore the concept of the Kardashian index(K-index),a term introduced by Hall in 2014.This metric provides a rudimentary means of evaluating whether a physician scientist's popularity on social media aligns with their significant scientific contributions.AIM To evaluate if a Gastroenterologist physician's popularity on social media is at par with their scientific contributions(research articles and publications).METHODS We conducted an extensive search to identify all gastroenterologists actively practicing and associated with the top 100 hospitals as reported by the United States News.We collected specific data on a sub-group including their names,affiliations,degrees,and sub-specializations.To gauge their social media popularity,we utilized the K-index calculation which is determined by dividing the actual number of Twitter followers by the number of researcher’s citations.The expected number of followers(F)is calculated using the formula F=43.3 C^0.32,where C represents the number of citations.RESULTS Physicians affiliated with the Mayo Clinic emerged as the most prominent presence on Twitter,constituting 16%of the total.They were followed closely by physicians from Mount Sinai Hospital(9%)and the University of Michigan Hospital(9%).Surprisingly,76%of the physicians evaluated exhibited a low K-index,falling within the range of 0 to less than 2.This suggests that a significant number of highly influential physician-scientists are not receiving due recognition,as indicated by their relatively low number of followers.On the other hand,24%of the physicians had an inflated K-index,exceeding 5,which positioned them as the"Kardashians".These individuals enjoyed greater social media popularity than their actual scientific contributions.Interestingly,our analysis revealed no discernible association between sex and K-index(P value of 0.92).CONCLUSION In the gastroenterology field,our study estimated that a majority(76%)of highly researched physicians are undervalued despite their significant scientific contributions.

文摘Geothermal resources are increasingly gaining attention as a competitive,clean energy source to address the energy crisis and mitigate climate change.The Wugongshan area,situated in the southeast coast geothermal belt of China,is a typical geothermal anomaly and contains abundant medium-and low-temperature geothermal resources.This study employed hydrogeochemical and isotopic techniques to explore the cyclic evolution of geothermal water in the western Wugongshan region,encompassing the recharge origin,water-rock interaction mechanisms,and residence time.The results show that the geothermal water in the western region of Wugongshan is weakly alkaline,with low enthalpy and mineralization levels.The hydrochemistry of geothermal waters is dominated by Na-HCO_(3)and Na-SO_(4),while the hydrochemistry types of cold springs are all Na-HCO_(3).The hydrochemistry types of surface waters and rain waters are NaHCO_(3)or Ca-HCO_(3).The δD and δ^(18)O values reveal that the geothermal waters are recharged by atmospheric precipitation at an altitude between 550.0 and 1218.6 m.Molar ratios of maj or solutes and isotopic compositions of^(87)Sr/^(86)Sr underscore the significant role of silicate weathering,dissolution,and cation exchange in controlling geothermal water chemistry.Additionally,geothermal waters experienced varying degrees of mixing with cold water during their ascent.Theδ^(13)C values suggest that the primary sources of carbon in the geothermal waters were biogenic and organic.Theδ^(34)S value suggests that the sulfates in geothermal water originate from sulfide minerals in the surrounding rock.Age dating using 3H and^(14)C isotopes suggests that geothermal waters have a residence time exceeding 1 kaBP and undergo a long-distance cycling process.

文摘AIM:To evaluate residents’perceptions and attitudes toward the various aspects of a comprehensive ophthalmic examination,and to determine if these factors correlate with their choices for fellowship and future career plans.METHODS:This is a cross-sectional study.A questionnaire on the perception of the ophthalmic exam was sent via SurveyMonkey to ophthalmology residents throughout Israel.Eighty of them(one-half of all ophthalmology residents in 2019)completed it.The first part related to how they perceived each component of the ophthalmic evaluation.The second part related to their future fellowship plans.The Chi-squared test was used to compare categorical variables and Student’s t-test and One-way ANOVA were used to compare continuous variables.Multivariate logistic regression analysis was applied as needed to detect interactions between variables and to exclude confounder effects.RESULTS:Slit-lamp examination of the anterior and posterior segments ranked as the most likeable aspects,whereas gonioscopy,ocular motility examination and visual acuity assessment were least likeable.Anterior segment and retina subspecialties were the ones most sought after.Forty-nine respondents(61.3%)noted a direct correlation between their preferred parts of comprehensive ophthalmic evaluations and their choice of subspecialty.Perceptions of selected components of those evaluations were significantly associated with responders’intentions to pursue anterior segment,retina,or oculoplastic fellowships(P<0.05).CONCLUSION:Perspectives of residents toward the ophthalmic examination,and most specifically its individual components,play an important role in their choice of subspecialty training.
文摘Background: Few studies have focused on the geographic and chronologic assessment of inclusivity and wellness in Obstetrics and Gynecology residency websites across the US. Objective: To identify variations in wellness and inclusivity website depictions across CREOG districts over the past two years. Methods: This is a cross-sectional analysis of the websites of ACGME-accredited OB/GYN residency programs across the United States between April 2022 and April 2023. The assessment was based on a compilation of 22 attributes devised and piloted by 49 medical students. A racially, geographically, and gender-diverse cohort of 11 students performed data collection. Results: A total of 560 websites were analyzed over two years. Wellness efforts remained unchanged in both years (website content, dedicated support personnel, and group activities). In 2023, a reduction in referencing of wellness (22%) and inclusivity (30%) occurred in leadership messaging. However, a 7% increase in the use of inclusive pronouns was noted. A reduction in gender diversity was identified (9% in faculty, 5% in residents), with programs favoring female-only teams. Similarly, a 7% reduction in the number of underrepresented in medicine faculty and residents was noted. A 15% reduction was noted in curricula referencing inclusivity in their mission statement and inclusivity focused research. Conclusions: This study suggests the variations across websites relative to inclusivity and wellness over the past two years. Updated websites may provide an accurate reflection of the offerings of programs and their investment in wellness and inclusivity across the nation.
