Leveraging User-Generated Comments and Fused BiLSTM Models to Detect and Predict Issues with Mobile Apps

In the last decade, technical advancements and faster Internet speeds have also led to an increasing number ofmobile devices and users. Thus, all contributors to society, whether young or old members, can use these mobileapps. The use of these apps eases our daily lives, and all customers who need any type of service can accessit easily, comfortably, and efficiently through mobile apps. Particularly, Saudi Arabia greatly depends on digitalservices to assist people and visitors. Such mobile devices are used in organizing daily work schedules and services,particularly during two large occasions, Umrah and Hajj. However, pilgrims encounter mobile app issues such asslowness, conflict, unreliability, or user-unfriendliness. Pilgrims comment on these issues on mobile app platformsthrough reviews of their experiences with these digital services. Scholars have made several attempts to solve suchmobile issues by reporting bugs or non-functional requirements by utilizing user comments.However, solving suchissues is a great challenge, and the issues still exist. Therefore, this study aims to propose a hybrid deep learningmodel to classify and predict mobile app software issues encountered by millions of pilgrims during the Hajj andUmrah periods from the user perspective. Firstly, a dataset was constructed using user-generated comments fromrelevant mobile apps using natural language processing methods, including information extraction, the annotationprocess, and pre-processing steps, considering a multi-class classification problem. Then, several experimentswere conducted using common machine learning classifiers, Artificial Neural Networks (ANN), Long Short-TermMemory (LSTM), and Convolutional Neural Network Long Short-Term Memory (CNN-LSTM) architectures, toexamine the performance of the proposed model. Results show 96% in F1-score and accuracy, and the proposedmodel outperformed the mentioned models.

Enhancing Multicriteria-Based Recommendations by Alleviating Scalability and Sparsity Issues Using Collaborative Denoising Autoencoder

A Recommender System(RS)is a crucial part of several firms,particularly those involved in e-commerce.In conventional RS,a user may only offer a single rating for an item-that is insufficient to perceive consumer preferences.Nowadays,businesses in industries like e-learning and tourism enable customers to rate a product using a variety of factors to comprehend customers’preferences.On the other hand,the collaborative filtering(CF)algorithm utilizing AutoEncoder(AE)is seen to be effective in identifying user-interested items.However,the cost of these computations increases nonlinearly as the number of items and users increases.To triumph over the issues,a novel expanded stacked autoencoder(ESAE)with Kernel Fuzzy C-Means Clustering(KFCM)technique is proposed with two phases.In the first phase of offline,the sparse multicriteria rating matrix is smoothened to a complete matrix by predicting the users’intact rating by the ESAE approach and users are clustered using the KFCM approach.In the next phase of online,the top-N recommendation prediction is made by the ESAE approach involving only the most similar user from multiple clusters.Hence the ESAE_KFCM model upgrades the prediction accuracy of 98.2%in Top-N recommendation with a minimized recommendation generation time.An experimental check on the Yahoo!Movies(YM)movie dataset and TripAdvisor(TA)travel dataset confirmed that the ESAE_KFCM model constantly outperforms conventional RS algorithms on a variety of assessment measures.

Rural collective construction land use in China: Policy issues and options

Land policy in China has been changed dramatically in the past two decades. Though the reform of rural farm land and the urban construction land has been launched successively, little has been done about the rural construction land by now, which has made a negative impact to the land utilization. This paper fi rst reviews the policy terms about the rural construction land, then gives a brief critique on them under the background of social-economic transformation in China, and discusses the driving forces and implications of institutional changes in the end. We think the further reform on the rural collective construction land is imperative. Firstly, as a production factor, it should be endowed with property attribute, and secondly the use right of rural construction land should be separated from its ownership so that it can be transacted in a competitive market, which will benefi t the building of harmonious society.

Identifying influencing factors and characterizing key issues in urban sustainable development capacity through machine learning

In response to the United Nations Sustainable Development Goals and China’s“Dual Carbon”Goals(DCGs means the goals of“Carbon Peak and carbon neutrality”),this paper from the perspective of the construction of China’s Innovation Demonstration Zones for Sustainable Development Agenda(IDZSDAs),combines carbon emission-related metrics to construct a comprehensive assessment system for Urban Sustainable Development Capacity(USDC).After obtaining USDC assessment results through the assessment system,an approach combining Least Absolute Shrinkage and Selection Operator(LASSO)regression and Random Forest(RF)based on machine learning is proposed for identifying influencing factors and characterizing key issues.Combining Coupling Coordination Degree(CCD)analysis,the study further summarizes the systemic patterns and future directions of urban sustainable development.A case study on the IDZSDAs from 2015 to 2022 reveals that:(1)the combined identification method based on machine learning and CCD models effectively quantifies influencing factors and key issues in the urban sustainable development process;(2)the correspondence between influencing factors and key subsystems identified by the LASSO-RF combination model is generally consistent with the development situations in various cities;and(3)the machine learning-based combined recognition method is scalable and dynamic.It enables decision-makers to accurately identify influencing factors and characterize key issues based on actual urban development needs.

Rural vulnerability,migration,and relocation in mountain areas of Western China:An overview of key issues and policy interventions

Western China features a vast area of mountains and high plateaus where millions of people,including diverse ethnic minority groups,have inhabited for generations.Geographically located in the mountainous,remote,and isolated regions,rural communities are prone to natural hazards and thus become vulnerable to impoverishment.To reduce rural vulnerability,many people residing in mountainous villages opted to out-migrate from their original villages and hometowns while some took in-situ adaptation measures.A host of government-sponsored resettlement programs have been carried out to help rural villagers seek alternative livelihoods elsewhere over the past four decades.To achieve a sustainable future for rural communities in mountainous areas of western China,more effective policies and measures need to be developed and enforced.

Performance Evaluation of Low-Cost Dual-Frequency GNSS Receivers for Precise Positioning in Senegal: Issues and Challenges

The development of this technology has favored the advances noted in recent years in the field of precise positioning. It has also paved the way for a wide range of research into the evaluation of their performance and reliability, their potential use in different fields, the improvement of performance and combined systems, etc. Single-frequency GNSS receivers, which for a long time remained the only category of low-cost GNSS receivers, often limited by their level of accuracy (metric) mainly due to their single-frequency nature, have been joined in the last decade by dual-frequency GNSS receivers developed by certain manufacturers of positioning equipment. These receivers now offer possible alternatives to the relatively expensive conventional (topographic quality) or geodetic receivers and. In this study, the performance of these low-cost dual-frequency receivers was evaluated in static and real-time kinematic GNSS positioning modes. Static positioning was carried out on three points with sessions of 2 h and 4 h over three days with antenna swapping (CHC i50, Leica GS14 and Emlid Reach RS2+). Real-time observations were carried out on eleven (11) points in open, poorly open and not at all open environments, in order to assess not only performance but also receiver sensitivity in environments with a high risk of multipath. The results obtained showed an average agreement of 2 cm in planimetry between the low-cost Emlid RS2+ receiver and the Leica GS14 and CHC i50 receivers. The differences in altimetry are nevertheless greater (sometimes up to decimetres for certain points). Real-time positioning results provided an average convergence of around 1 cm on the E, N and H components with the results from the low-cost Emlid Reach RS2+ and Ublox ZED-F9P receivers and the CHC i50 receiver. Analysis of the results obtained has enabled us to highlight the various issues and challenges associated with this new generation of GNSS receivers, with a view to enhancing their appropriation and optimal integration in the professional and research worlds.

Cross-sectional population based study ascertaining the characteristics of US rural adults with mental health concerns who perceived a stigma regarding mental health issues

Introduction: Mental health is an important component of overall health. Mental illness is a leading cause of morbidity and mortality in the US and is associated with chronic diseases such as heart disease, diabetes, and arthritis. In the US, most people with mental health issues or disorders remain untreated. Epidemiological studies have identified rural residents as being at greater risk for health disparities;as a result, rural residents are a vulnerable population in terms of mental health and mental health care. Research has demonstrated that perceived stigma can be a significant barrier to rural residents seeking mental health care. This study examined the research question: What are the characteristics of US rural adults with mental health concerns who perceived stigma? Methods: 2007 Behavioral Risk Factor Surveillance System (BRFSS) data were analyzed using bivariate and multivariate techniques to answer the research question. 2007 BRFSS data were used because in that year non-institutionalized US adults in 37 states and territories were queried about their attitudes toward mental illness. BRFSS is a random digit telephone survey that uses a complex multi-stage sampling approach and subsequently a weighting factor is calculated for application to the data in order to ensure that they are representative of the US population based on the most recent census data. Only weighted data were analyzed. Results: Logistic regression analysis revealed that rural adults reporting mental health concerns who perceived stigma regarding mental health were more likely to be unemployed seeking work or not working and not seeking work, military veterans, or to have deferred medical care because of cost. They were also more likely to not have a health care provider and to rarely or never feel supported emotionally. Conclusions: Support systems may render people with mental health issues less vulnerable to perceiving stigma, thus assisting with removing stigma as a barrier to care. Pharmacist may play a role as support in communities, especially where access to health care providers may be limited.

Issues of Expansion of China Rural Resident Consumption

The international financial crisis on our economic development resulted in the inevitable impact on Chinese economy. In order to get rid of the impact, the expansion of domestic demand has been a crucial means of steady economic growth in China. However, the farmers over seven million account for a large proportion should be the main consumers in China. On the contrary, the current lack of domestic demand in China, which is mainly in rural consumption, is the lack of the critical issues of our efforts to expand domestic demand. This paper clarified the factors restricting China rural residents＇ consumption demand expansion, and on this basis explored the expansion of rural residents＇ consumption demand countermeasures. Empirical analysis was used to prove the low level of income of rural residents＇ constraints, and also to expose the fact that social security system was imperfect. Meanwhile, rural infrastructure restricted the consumption level of rural residents. The consumer market is an effective way to improve rural residents＇ consumption demand.

Study on Regulatory Issues of Environmental Laws of Rural Tourism in China

In recent years, rural tourism in China vigorously developed, which promoted economic and social development in rural area. However, serious environmental problems appeared in the development process of rural tourism since rural tourism lacked effective and comprehensive super- vision. These environmental problems included environmental pollution and ecological damage. However, environmental legal system about rural tourism had many problems, such as the lagged legislation, the absence of law enforcement supervision, imperfect judicial system and weak law- abiding awareness. Therefore, it became the solution to solve environmental problems brought by rural tourism in China, and was also the safe- guard for promoting sustainable development of rural tourism in China to establish a sound legal system for rural tourism, implement strict law en- forcement supervision of rural tourism, build litigation system of environmental public interest and enhance law-abiding awareness of rural tourism. For legal defects of regulating rural tourism and its induced environmental problems in China, we tried to perfect regulation of environmental law for rural tourism in China.

A Study on the Remarriage Issues of the Rural Elderly

Our aging process, at the same time, the number of single elderly population is increasing year by year, which makes the elderly remarriage problem becomes more serious. With the acceleration of urbanization process in China, economic development gap between urban and rural areas is widening, resulting in a lot of social problems, of which there are a lot of weak social groups in the cultural and economic level is relatively backward rural areas. Thought to be bound by their material conditions is not high, in the face of social problems even more weak, and they lost even among the elderly also faces remarry rare status quo. Rural elderly remarriage can be resolved related to quality of life and how happy they are old age, so this research will focus on the vast rural areas. After the Rongcheng County of Baoding, Hebei Province and five ordinary village Yixian interviews conducted, combined with a large research literature summed up his own research ideas and research methods. Find out China＇s rural elderly remarriage even lose relevance, problems and influence factors, and the corresponding countermeasures and suggestions： the elderly themselves from both the individual and the external environment to solve. Elderly people to establish a correct view of marriage and spouse, and actively carry out another marriage personal preparation. External environmental needs of the family, society and country in three areas to work together to form a joint force to support the establishment of Trinity molding system from three angles.

Peri-urban Development:Discussion with Land Use Zoning,Statutory Provision,and Issues inside Katahari Rural Municipality,Nepal

The peri-urban area is a transitional zone between the city and its hinterlands characterized by mixed land use and intensive flows of resources,people,goods,and services from and to the city center.These zones are generally misguided and haphazardly developed without a proper planning framework.The peri-urban area at present will be the urban area in the future;therefore,it needs planning intervention in its initial stage of growth.Katahari,a peri-urban area of Biratnagar metropolitan city,is developing a spontaneous lack of land use plans.Recently,the Government of Nepal has encouraged the local government to implement land use plans in the provided framework,policy,and guidelines.This study,in this context,attempts to analyze and identify land use issues and potential zones for Katahari rural municipality that also supports planning urban development in the future.The study is based on primary and secondary data and information supported by maps and figures.It is concluded that Katahari has been developed as a multi-function center adjoining the Biratnagar metropolitan city,and future expansion of the city will cover a wide range of rural municipalities.The postal highway that passes through it has attracted a wide range of urban functions.Agriculture,residential,commercial,and industrial are the main land use category at present and needs development control through providing land use zoning and related planning instruments through the increasing role of the stakeholder and the government agencies in the decision-making processes and implementation of spatial development frameworks to regulate peri-urban development in the area which will guide the future planning for liability,economic viability,social inclusion,and environmental sustainability in the area.Spill-over development activities of Biratnagar,have increased the number of economic activities,population growth,and mixed-use development.

From Quantitative Issues to Structural Ones: An Interpretation of China's Labor Market

Based on the latest demographic and labor data, this paper reveals the changes in China＇s labor supply and demonstrates that China＇s key employment issues are no longer quantitative contradictions but increasingly have become structural issues related to labor market mismatch. Due to real and potential economic growth rates being consistent, cyclical unemployment is, at least for now, not striking. If traditional policy measures continue to be followed in disregard of frictional and structural attributes of the labor market to increase total employment, not only will China＇s employment issues persist but new labor market problems may arise as well China should focus on addressing structural unemployment contradictions.

The States-of-arts and Key Scientific Issues on Durability Research of Concrete Structures

Concrete has traditionally been regarded as a durable material requiring little or no maintenance. However, over the past several decades, a number of durability related problems have emerged and stimulated research into the factors relating to concrete durability globally. The challenge now facing practicing engineers is how to design and build structures that not only satisfy the specified structural requirements, but also achieve the performance levels required from a durability standpoint. Research works on concrete structural durability have been widely reported in the literature over the last several decades. In this paper, reviews of four stages of research work on durability, i e, environments, materials, components, and structures, were presented. Afterwards, the key scientific issues in this field were also pointed out.

Environmental Issues Related to Chemical Fertilizer Use in China

The current status of chemical fertilizers production and consumption in China as well as their important roles in Chinese modern agriculture are discussed with special concerns to the environmental issues related to chemical fertilizer use. On the one hand, the total amount of chemical fertilizer produced is insufficient to meet the agricultural needs. On the other hand, the production and consumption of chemical fertilizers in China are obviously not balanced. In some areas over application of nitrogen fertilizers and loss of phosphate fertilizer due to soil erosion have resulted in some undesirable environmental problems such as increase of nitrate in water and eutrophication of water bodies. Maximum scientific uses of organic manures in combination with reasonable use of chemical fertilizers are part of good practices not only in increasing soil productivity and keeping sustainable agriculture development but also in mimimizing their detrimental effects on the environment.
