In this regard, addressing the issue of productivity in rice production is very important due to its essential role in feeding different sections of society, providing food security, reducing dependence on imports and foreign exchange, strengthening trade interactions with other countries, generating income, creating employment, creating balance in the business and capital market, and many other issues. In 2022, Mazandaran Province produced 1.6 million tons of paddy as a strategic product, responsible for 44.47% of Iran's paddy production, and in this sense, it has been ranked first in the country. This province has long been known as the hub of rice production, and this user product, having about 76% of Mazandaran's irrigated crop area, has always made an important contribution to the province's employment. For this purpose, the present study aimed to identify factors affecting the prosperity of the rice production business in Mazandaran Province, focusing on measuring the inefficiency of various production inputs, especially the labor force.\nMethods: Three institutional, managerial, and policy-market criteria effective in the prosperity of rice production business were extracted in this study. The input criterion includes all production factors affecting the productivity of this product, which includes eight subcriteria as water, labor, land, fertilizer, poison, machinery, capital, and seed. The management criterion is all management actions by relevant organizations and bodies (Jahad Keshavarzi, Regional Water, Room of Commerce), which includes six regulatory, executive, organizational, service, and innovation options. The political-market criterion also covered the macro-government policies that can affect the productivity of rice, and there are six financial, economic, structural, commercial, marketing, and strategic development options. Thus, 19 effective options in the productivity of rice production were considered in this study. In this study, factors affecting the productivity of this product were exracted and prioritized using the Analytical Hierarchy Process (AHP) method, measuring the production efficiency of important cultivars of this product (high-quality rice and high-yielding rice) using the data envelopment analysis method (DEA), and then examining productivity changes over time using the Malmquist Index (MI). The data needed for identifying and prioritizing factors in this research were collected by designing a questionnaire, which was completed based on the opinions of 18 experts, including those from the Agricultural Jihad Organization of Mazandaran Province and Sari City, as well as the academic community. The statistics and information of the Agricultural Jahad Organization of the province were used to complete the data in measuring the productivity of production and efficiency of inputs.\nResults: The results indicate that among the eight production factors, water, mechanization, and land are the most important input factors in rice production with weights of 0.36, 0.2, and 0.14, respectively. Among the five management factors, benefiting from the opinions of agricultural experts, implementing the optimal cultivation pattern of crops according to the climatic conditions and the status of water resources in the province, and using new technologies in agricultural operations with weights of 0.40, 0.25, and 0.14, respectively, were known as three important and superior factors for the management of rice production business. In addition, the financial, economic options, and improvement of the structure of the rice product marketing system were determined with the weights of 0.30, 0.22, and 0.19, respectively, as three policy-market subcriteria affecting the rice productivity of this province. Based on the findings in the agricultural year of 2017-2018 in the east of this province, Qaemshahr City, the land, machinary, poison, and fertilizer inputs were inefficient at 52.68%, 48.26%, 34.37%, and 33.16%, respectively. In 2018, the inefficiency rates in the use of land, labor, and poison inputs were 71.36%, 15.09%, and 4.46%, respectively. In the production of high-yielding rice in the east of the province, there has been inefficiency in the use of land, machinary, seed, water, and fertilizer inputs. Accordingly, Behshahr City acted inefficiently in consuming the mentioned inputs by 68.29, 52.60, 16.65, 12.63, and 7.55%, respectively. In 1998, the cities of Behshahr and Neka acted inefficiently in the consumption of all the investigated inputs, except for machinery. The percentages of inefficiency in the labor input are 16.14 and 42.07%, respectively. In addition, the productivity growth index values of Malmquist in the production of high-quality rice and high-yielding rice are 1.155 and 1.094, respectively. Hence, it can be concluded that the production productivity of this product has increased in this province.\nConclusion: The results indicate that the productivity of different rice varieties has increased during the studied period. In the case of high-yielding rice, however, the technical efficiency of producers in newer technology is lower than in older technology. Therefore, it is necessary for trustee organizations and knowledge-based companies to invest in the research, innovation, and promotion of new technology in training to use this technology. In this study, \"water\" has been determined as the most important input affecting the productivity of this product; therefore, it is recommended to take necessary measures to promote water storage and reduce its consumption. It is also suggested to provide financial support to rice farmers and the development of knowledge-based companies to provide new irrigation systems. Referring to the results of this study, the use of \"machinery\" is considered the second most effective factor in increasing productivity. In addition to reducing the cost of manpower and saving time, the uniformity and accuracy of the work are increased with mechanized cultivation, and seedlings are exposed to less damage. However, this issue does not mean to ignore the role and importance of the workforce in the production and elimination of job opportunities. Rather, it is recommended to train skilled and specialized human resources to benefit from mechanization for the long-term stability of the rice production business and stable rural employment.","source":"DOAJ","year":2025,"language":"","subjects":["Agriculture (General)","Agricultural industries"],"url":"http://jea.sanru.ac.ir/article-1-409-en.pdf","pdf_url":"http://jea.sanru.ac.ir/article-1-409-en.pdf","is_open_access":true,"published_at":"","score":69},{"id":"doaj_10.1016/j.heliyon.2025.e44076","title":"Application of the RANAS model of behavior change for source separation of domestic solid wastes","authors":[{"name":"Mehdi Mirzaei-Alavijeh"},{"name":"Kiomars Sharafi"},{"name":"Mojtaba Haeidari-Chegeni"},{"name":"Farzad Jalilian"}],"abstract":"The lack of people's involvement in recycling and separating household waste is a major factor contributing to the ongoing rise in waste production globally. This study aimed to identify the key psychological and social factors that influence Waste Separation Behaviors (WSB) among Iranian households. The RANAS (Risks, Attitudes, Norms, Abilities, and Self-regulation) approach was utilized for this purpose. In Kermanshah, a city in western Iran, a total of 1504 households were invited to participate in this cross-sectional study. Out of these, 1374 households agreed to take part. To gather data, a written questionnaire was used to assess demographic characteristics, factors of the RANAS model, and domestic solid WSB at the source. The mean age of the participant was 40.74 [SD: 9.51] years. Gender (women) (Beta = 0.136), educational level (Beta = 0.100), family economic status (Beta = 0.142), housewife (Beta = 0.150), attitude (Beta = 0.324), Perceived Behavior Control (PBC) (Beta = 0.103), and commitment (Beta = 0.193) had significant effects on WSB at the source among the Iranian households. Collectively, the variables accounted for 34 % of the variation in WSB at the source, F = 31.520, P \u003c 0.001. Our findings indicate that the level of WSB at the source was low in western Iran. These results serve as a warning to environmental policy makers and health planners in Iran, highlighting the need for the development and implementation of educational planning. These findings also emphasize the importance of educational programs that focus on increasing attitude, commitment, and PBC.

Generating 4D cities is more challenging than 3D scenes due to the presence of structurally complex, visually diverse objects like buildings and vehicles, and heightened human sensitivity to distortions in urban environments. To tackle these issues, we propose CityDreamer4D, a compositional generative model specifically tailored for generating unbounded 4D cities. Our main insights are 1) 4D city generation should separate dynamic objects (e.g., vehicles) from static scenes (e.g., buildings and roads), and 2) all objects in the 4D scene should be composed of different types of neural fields for buildings, vehicles, and background stuff. Specifically, we propose Traffic Scenario Generator and Unbounded Layout Generator to produce dynamic traffic scenarios and static city layouts using a highly compact BEV representation. Objects in 4D cities are generated by combining stuff-oriented and instance-oriented neural fields for background stuff, buildings, and vehicles. To suit the distinct characteristics of background stuff and instances, the neural fields employ customized generative hash grids and periodic positional embeddings as scene parameterizations. Furthermore, we offer a comprehensive suite of datasets for city generation, including OSM, GoogleEarth, and CityTopia. The OSM dataset provides a variety of real-world city layouts, while the Google Earth and CityTopia datasets deliver large-scale, high-quality city imagery complete with 3D instance annotations. Leveraging its compositional design, CityDreamer4D supports a range of downstream applications, such as instance editing, city stylization, and urban simulation, while delivering state-of-the-art performance in generating realistic 4D cities.","source":"arXiv","year":2025,"language":"en","subjects":["cs.CV"],"doi":"10.1109/TPAMI.2025.3603078","url":"https://arxiv.org/abs/2501.08983","pdf_url":"https://arxiv.org/pdf/2501.08983","is_open_access":true,"published_at":"2025-01-15T17:59:56Z","score":69},{"id":"arxiv_2507.12267","title":"Orchestrating the Implementation of the Smart City","authors":[{"name":"Filippo Marchesani"}],"abstract":"This chapter explores the six core dimensions of smart cities (i.e. smart economy, mobility, environment, people, living, and governance) emphasizing their interdependence and the need for holistic orchestration.

In light of China’s commitment to achieving carbon neutrality and transitioning to a low-carbon society, it is crucial to control waste generation at its source, as the waste management sector is highly polluting and contributes substantially to carbon emissions. Adopting the 3R (reduce, reuse, and recycle) approach, reducing the quantity of waste is the priority in waste management. Therefore, exploring rural residents’ willingness to adopt the “pay as you throw” (PAYT) policy in underdeveloped mountainous areas and the factors influencing this willingness is highly valuable. This paper adopts the Contingent Valuation Method (CVM) with a face-to-face questionnaire survey, involving 1429 farmers from six cities around the underdeveloped mountainous area in Northwestern China. It measures their willingness to pay (WTP) and preferred payment levels for the PAYT policy. Based on the theory of planned behavior, the paper finds that farmers’ environmental knowledge, environmental awareness and social trust positively influence their WTP, while farmers’ perception of pollution and daily waste disposal do not significantly impact their WTP. Additionally, social trust negatively moderates the relationship between environmental knowledge and WTP. This paper provides empirical results that can support the implementation of a nationwide waste fee management system and the promotion of volume-based waste fee management. It also offers targeted suggestions for the government to establish PAYT and improve the efficiency of rural household waste management in rural China.","source":"Semantic Scholar","year":2024,"language":"en","subjects":null,"doi":"10.3390/su162310204","url":"https://www.semanticscholar.org/paper/82478cc7f9b13dc61b5e00c8d6e18cd270c929e5","pdf_url":"https://doi.org/10.3390/su162310204","is_open_access":true,"citations":1,"published_at":"","score":68.03},{"id":"doaj_10.1344/ara.v14i1.44418","title":"Gestión y turismo termal.

Recently 3D Gaussian Splatting (3D-GS) has emerged as a highly efficient alternative for object-level 3D generation. However, adapting 3D-GS from finite-scale 3D objects and humans to infinite-scale 3D cities is non-trivial. Unbounded 3D city generation entails significant storage overhead (out-of-memory issues), arising from the need to expand points to billions, often demanding hundreds of Gigabytes of VRAM for a city scene spanning 10km^2. In this paper, we propose GaussianCity, a generative Gaussian Splatting framework dedicated to efficiently synthesizing unbounded 3D cities with a single feed-forward pass. Our key insights are two-fold: 1) Compact 3D Scene Representation: We introduce BEV-Point as a highly compact intermediate representation, ensuring that the growth in VRAM usage for unbounded scenes remains constant, thus enabling unbounded city generation. 2) Spatial-aware Gaussian Attribute Decoder: We present spatial-aware BEV-Point decoder to produce 3D Gaussian attributes, which leverages Point Serializer to integrate the structural and contextual characteristics of BEV points. Extensive experiments demonstrate that GaussianCity achieves state-of-the-art results in both drone-view and street-view 3D city generation.

Almost all the participants (91.2%) had been tested for HIV, with 68.8% tested a minimum of three times. Despite this, sexual risk behaviour was high. Despite the high level of knowledge of HIV transmission, there was no relationship between HIV knowledge and adoption of behaviours for the prevention of HIV transmission (p = .457). However, bivariate analysis showed an association between transactional sex and living in informal housing (OR = 31.94, 95% CI: 5.65–180.63, p \u003c .001). Living in informal housing was also associated with having multiple current sexual partners (OR = 6.30, 95% CI: 1.39–28.42, p = .02). Multivariate analysis, after adjusting for all other factors, indicated that the odds of having transactional sex was increased by 23 times in those who did not have formal housing (OR = 23.306, 95% CI: 3.97–144.59, p = .001). Qualitative responses showed that women perceived poverty as the overarching factor determining the lifestyle choices which impacted their health. They indicated a need for employment opportunities and provision of housing to alleviate both poverty as well as transactional sex. Although, participants from this study understood the benefits of the protective behaviours to prevent HIV transmission, economic and social factors do not afford this vulnerable group the opportunity nor the motivation to adopt such behaviours. In the current climate of increasing unemployment and escalating GBV, urgent interventions are needed in terms of employment opportunities and empowerment drives to prevent an increase in HIV transmission.","source":"DOAJ","year":2023,"language":"","subjects":["Public aspects of medicine"],"doi":"10.1080/17290376.2023.2185806","url":"https://www.tandfonline.com/doi/10.1080/17290376.2023.2185806","is_open_access":true,"published_at":"","score":67},{"id":"doaj_10.1344/ara.v12i1.41127","title":"La Situación económica del Turismo comunitario en Candelaria, Campeche post COVID-19","authors":[{"name":"Ludwin Estrada Ramirez"},{"name":"Paula Viveros Moreno"},{"name":"Arianna del Ángel Pacheco May"},{"name":"Maximiliano Vanoye Eligio"}],"abstract":"\nEl sector turístico fue duramente afectado por la pandemia del coronavirus (COVID-19) durante los dos últimos años, causando repentinamente su caída debido a la prohibición de realizar viajes a los sitios turísticos de todo el mundo.

While most of recent neural rendering works focus on objects and small-scale scenes, developing neural rendering methods for city-scale scenes is of great potential in many real-world applications. However, this line of research is impeded by the absence of a comprehensive and high-quality dataset, yet collecting such a dataset over real city-scale scenes is costly, sensitive, and technically difficult. To this end, we build a large-scale, comprehensive, and high-quality synthetic dataset for city-scale neural rendering researches. Leveraging the Unreal Engine 5 City Sample project, we develop a pipeline to easily collect aerial and street city views, accompanied by ground-truth camera poses and a range of additional data modalities. Flexible controls over environmental factors like light, weather, human and car crowd are also available in our pipeline, supporting the need of various tasks covering city-scale neural rendering and beyond. The resulting pilot dataset, MatrixCity, contains 67k aerial images and 452k street images from two city maps of total size $28km^2$. On top of MatrixCity, a thorough benchmark is also conducted, which not only reveals unique challenges of the task of city-scale neural rendering, but also highlights potential improvements for future works. The dataset and code will be publicly available at our project page: https://city-super.github.io/matrixcity/.","source":"arXiv","year":2023,"language":"en","subjects":["cs.CV"],"url":"https://arxiv.org/abs/2309.16553","pdf_url":"https://arxiv.org/pdf/2309.16553","is_open_access":true,"published_at":"2023-09-28T16:06:02Z","score":67},{"id":"arxiv_2309.00610","title":"CityDreamer: Compositional Generative Model of Unbounded 3D Cities","authors":[{"name":"Haozhe Xie"},{"name":"Zhaoxi Chen"},{"name":"Fangzhou Hong"},{"name":"Ziwei Liu"}],"abstract":"3D city generation is a desirable yet challenging task, since humans are more sensitive to structural distortions in urban environments. Additionally, generating 3D cities is more complex than 3D natural scenes since buildings, as objects of the same class, exhibit a wider range of appearances compared to the relatively consistent appearance of objects like trees in natural scenes. To address these challenges, we propose \\textbf{CityDreamer}, a compositional generative model designed specifically for unbounded 3D cities. Our key insight is that 3D city generation should be a composition of different types of neural fields: 1) various building instances, and 2) background stuff, such as roads and green lands. Specifically, we adopt the bird's eye view scene representation and employ a volumetric render for both instance-oriented and stuff-oriented neural fields. The generative hash grid and periodic positional embedding are tailored as scene parameterization to suit the distinct characteristics of building instances and background stuff. Furthermore, we contribute a suite of CityGen Datasets, including OSM and GoogleEarth, which comprises a vast amount of real-world city imagery to enhance the realism of the generated 3D cities both in their layouts and appearances. CityDreamer achieves state-of-the-art performance not only in generating realistic 3D cities but also in localized editing within the generated cities.","source":"arXiv","year":2023,"language":"en","subjects":["cs.CV"],"url":"https://arxiv.org/abs/2309.00610","pdf_url":"https://arxiv.org/pdf/2309.00610","is_open_access":true,"published_at":"2023-09-01T17:57:02Z","score":67},{"id":"arxiv_2304.07500","title":"The 7th AI City Challenge","authors":[{"name":"Milind Naphade"},{"name":"Shuo Wang"},{"name":"David C.

The 2023 challenge had five tracks, which drew a record-breaking number of participation requests from 508 teams across 46 countries. Track 1 was a brand new track that focused on multi-target multi-camera (MTMC) people tracking, where teams trained and evaluated using both real and highly realistic synthetic data. Track 2 centered around natural-language-based vehicle track retrieval. Track 3 required teams to classify driver actions in naturalistic driving analysis. Track 4 aimed to develop an automated checkout system for retail stores using a single view camera. Track 5, another new addition, tasked teams with detecting violations of the helmet rule for motorcyclists. Two leader boards were released for submissions based on different methods: a public leader board for the contest where external private data wasn't allowed and a general leader board for all results submitted. The participating teams' top performances established strong baselines and even outperformed the state-of-the-art in the proposed challenge tracks.","source":"arXiv","year":2023,"language":"en","subjects":["cs.CV"],"url":"https://arxiv.org/abs/2304.07500","pdf_url":"https://arxiv.org/pdf/2304.07500","is_open_access":true,"published_at":"2023-04-15T08:02:16Z","score":67},{"id":"ss_7aaaf1b7be832c56ec2fb172585fb38c17ac9b85","title":"Satisfaction of family physician team members in the context of contract system: A cross-sectional survey from Shandong Province, China","authors":[{"name":"Weiqin Cai"},{"name":"Yuan-Ze Du"},{"name":"Qianqian Gao"},{"name":"Runguo Gao"},{"name":"Hongqing An"},{"name":"Wenwen Liu"},{"name":"Fang Han"},{"name":"Qi Jing"},{"name":"Chunping Wang"}],"abstract":"Background Family physicians play a key role in responding to the growing demand for primary healthcare due to aging. The work attitude of family physician team members (FPTMs) impacts their work efficiency and quality. Knowing how satisfied they are with their jobs can help identify potential directions and entry points for incentives. The purpose of this study is to analyze the job satisfaction status and influencing factors of grassroots health service personnel after the implementation of the family physician contract system in China. Methods The study conducted a cross-sectional survey with 570 FPTMs in three prefecture-level cities in the Shandong Province. Satisfaction was measured using 30 items across seven dimensions. Responses were recorded on a 5-point Likert scale. Descriptive statistical analysis was used to analyze the general information and satisfaction of FPTMs. Multiple linear regression analysis was used to analyze the factors influencing job satisfaction. Results The overall job satisfaction among FPTMs was not high. Among the seven dimensions, interpersonal relationships had the highest satisfaction (4.10 ± 0.78), while workload had the lowest satisfaction (3.08 ± 0.56). The satisfaction levels of the three sample regions were different, and the results were opposite to their regional economic development levels. The results of the multifactor analysis showed that gender, income level, educational background, working years, daily working hours, number of training sessions per year and the proportion of performance pay had significant impact on overall job satisfaction. Conclusions The development of a family physician contract system has increased the workload of FPTMs. In addition to the implementation of the new policy, attention should be paid to the workload and working attitude of family physicians. The fundamental measures should focus on attracting more personnel to work at the grassroots level by accelerating education and training to solve the problem of insufficient health personnel at the grassroots level. Simultaneously, attention should be paid to the improvement of the medical staff's salary level and the need for self-promotion, such as training.","source":"Semantic Scholar","year":2022,"language":"en","subjects":["Medicine"],"doi":"10.3389/fpubh.2022.1000299","url":"https://www.semanticscholar.org/paper/7aaaf1b7be832c56ec2fb172585fb38c17ac9b85","pdf_url":"https://www.frontiersin.org/articles/10.3389/fpubh.2022.1000299/pdf","is_open_access":true,"citations":4,"published_at":"","score":66.12}],"total":3208737,"page":1,"page_size":20,"sources":["Semantic Scholar","DOAJ","CrossRef","arXiv"],"query":"The city as an economic factor.
