The reorganization of the global production network and the increased mobility of urban-rural elements have accelerated the differentiation of rural spaces,resulting in a trend towards specialization in rural areas.This paper focuses on the concept of specialization,and takes a renowned bonsai specialized village in Guangzhou City,China as a typical case to explore its transformation and development process,action logic and coupling mechanism with the social governance.The results show that:1)the development of rural specialization in Ruiling Village is shaped by several key actors,such as local governments,grassroots organizations,villagers,social organizations,policies,markets and infrastructure.The transfer of these key actors and the reconstruction of actor-networks in different stages have an important influence on the transformation and realization of rural development goals.2)Through subjects-driven,organization management and resource connection,social governance supports the specialization of rural industrial organization,operation,technology and mode.The governance structure shifts from decentralization to networking,refinement and integration.A coupling community of social governance and specialization is created by the social governance system of‘local government-grassroots organizationseconomic cooperatives-villagers’,which links industries,industrial chains and cooperatives.3)Social governance integrates into the value chain extension process of rural specialized development with a central,multi-level organizational structure.It promotes the construction of the whole value chain through organizational planning,resource integration and image shaping,thus realizing the value,branding and organization of the industry,as well as the integration of rural sustainable development and governance mechanism.Social governance has a profound impact on the development of rural specialization in terms of subject,structure and mode,and participates in the construction of the whole value chain of rural areas.This paper provides a new perspective for understanding the coupling effect of social governance in the rural development transformation,and promotes the rural sustainable development and governance. 展开更多

Background: Many countries across the world are facing an ongoing shortage of midwife practitioners due to several reasons such as increased workload, working overtime, poor-quality midwifery care, low staff morale, stress and burnout, lack of opportunity for training, lack of management support, financial issues and lack of recognition and compromised autonomy. Purpose: To explore the reasons behind nurses’ hesitance to apply for midwifery specialization. The objectives of this study were to understand the challenges that lie in front of Omani nurses and the motivational factors to apply for a midwifery programme. Method: Exploratory qualitative study was conducted at the largest tertiary hospital in Oman. Purposive sampling was applied for participant recruitment. Face-to-face interviews and focus group discussions were used as data collection methods. The study included general nurses, nurses in charge working in the maternity unit as well as nurses whose applications were accepted for midwifery education. Qualified midwives were excluded. The data collection process yielded twenty-five nurses. The interview protocol highlighted the impact and perception of the midwifery specialization on nurses’ careers. Thematic analysis was employed for data analysis. Results: Three over-arching major themes were identified. These are 1) nurses’ perceptions about the nature of work in maternity wards, the nurses have positive perception toward working in maternity wards and labor room because of working exclusively with female patients and their babies 2) factors influencing the decision to study midwifery specialization, work overload, stress, lack of support from administration were the most common reason behind the nurses not to apply for midwifery specialization and 3) support and recommendations required for midwives, the nurses mentioned that their identity, promotions and support from the administration will encourage them to apply for midwifery specialization. Conclusion: One of the main reasons that hindered nurses from applying to midwifery specialization is the false belief that midwives cannot work outside the delivery suite (DS). The second reason was the stress that midwives encounter at DS, and this was perceived by general nurses who did not work at DS. These challenges could be mitigated by leadership support, midwifery profession identity, as well as financial recognition for the midwives. 展开更多

In light of the growth in vertically specialized in global trade,the present paper uses input-output tables from the World Input-Output Database to construct an environmental multiregional input-output model to calculate the CO_2 emissions embodied in China's international trade during 1995-2009.The advantage of this model lies in its incorporation of the reexported CO_2emissions component embodied in trade and its ability to differentiate domesticsourcedCO_2 emissions from foreign-sourced CO_2 emissions in trade.The results show that carbon emissions embodied in both China's exports and imports increased significantly during 1995-2009.One important reason for this is that the re-exported carbon emissions embodied in China's imported intermediate inputs increased substantially during this period.Our research reveals that accelerating the transformation of trade pattern and upgrading processing trade should be emphasized in the formulation of policy to prompt CO_2 emissions abatement in China. 展开更多

Phytochromes mainly function in photoautotrophic organisms to adjust growth in response to fluctuating light signals.The different isoforms of plant phytochromes often display both conserved and divergent roles,presumably to fine-tune plant responses to environmental signals and optimize fitness.Here we describe the distinct,yet partially redundant,roles of phytochromes NaPHYA,NaPHYB1 and NaPHYBi in a wild tobacco species,Nicotiana attenuata using RNAi-silenced phytochrome lines.Consistent with results reported from other species,silencing the expression of NaPHYA or NaPHYBi in N.attenuata had mild or no influence on plant development as long as NaPHYBi was functional;whereas silencing the expression of NaPHYBi alone strongly altered flowering time and leaf morphology.The contribution of NaPHYB2 became significant only in the absence of NaPHYB1;plants silenced for both NaPHYBi and NaPHYB2 largely skipped the rosettestage of growth to rapidly produce long,slender stalks that bore flowers early:hallmarks of the shadeavoidance responses.The phenotyping of phytochrome-silenced lines,combined with sequence and transcript accumulation analysis,suggest the independent functional diversification of the phytochromes,and a dominant role of NaPHYBi and NaPHYB2 in N.attenuata's vegetative and reproductive development. 展开更多

The cerebellum is critical for controlling motor and non-motor functions via cerebellar circuit that is composed of defined cell types, which approximately account for more than half of neurons in mammalsThe molecular mechanisms controlling developmental progression and maturation processes of various cerebellar cell types need systematic investigationHere, we analyzed transcriptome profiles of 21119 single cells of the postnatal mouse cerebellum and identified eight main cell clusters. Functional annotation of differentially expressed genes revealed trajectory hierarchies of granule cells (GCs) at various states and implied roles of mitochondrion and ATPases in the maturation of Purkinje cells (PCs), the sole output cells of the cerebellar cortexFurthermore, we analyzed gene expression patterns and co-expression networks of 28 ataxia risk genes, and found that most of them are related with biological process of mitochondrion and around half of them are enriched in PCs. Our results also suggested core transcription factors that are correlated with interneuron differentiation and characteristics for the expression of secretory proteins in glia cells, which may participate in neuronal modulationThus, this study presents a systematic landscape of cerebellar gene expression in defined cell types and a general gene expression framework for cerebellar development and dysfunction. 展开更多

Specialized households serve as the primary units within specialized villages in China,and their capacity to withstand risks and external influences significantly shapes the future trajectory of specialized villages and the overall vitality of the rural economy.In this study,we established a measurement indicator system based on the definition of specialized households’resilience,elucidating the logical connection between specialized households’resilience and rural industrial development in China.The musical instrument industry in Lankao County,Henan Province of China,was employed as a case;survey data,the entropy method,and an obstacle diagnosis model were used to examine how instrument production specialized households responded to the challenges posed by Corona Virus Disease 2019(COVID-19)and the tightening of national environmental protection policies,yielding the following key findings:1)there exists substantial variation in the comprehensive resilience levels among different specialized households;2)the ability to learn and adapt is the most significant contributor to the overall resilience level of specialized households;3)technological proficiency and access to skilled talent emerge as pivotal factors influencing specialized households’resilience;4)the positioning of specialized households within the industrial supply chain and the stability of their income have a direct bearing on their resilience level.The influence of specialized households’resilience on industrial development primarily manifests in the following ways:stronger resilience correlates with increased stability in production and sales,fostering a more proactive approach to future actions.However,heightened exposure to the external macroeconomic environment can lead to a higher rate of export reduction.To enhance the development resilience of entities like specialized households and family farms,and to invigorate rural economic development,escalating investments in rural science and technology and prioritizing the training of technical talent become imperative. 展开更多

Background: The most prevalent non-communicable disease worldwide is oral health-related disease, with dental caries and periodontal conditions being common. Oral health status significantly impacts overall health and quality of life. Barriers to dental care affect children with special needs. This study evaluates the oral health status and treatment requirements of people with special needs. Methodology: This descriptive cross-sectional study in Kumasi, Ghana examined oral health status among people, 121 children with special needs over two months, in June-July 2022. Dental caries, periodontal changes, malocclusion, and trauma were assessed. The data was analyzed using SPSS 20.0. Results: The oral health status among people with special needs in this study was generally moderate, with a range from very good to very poor. The prevalence of dental caries was 37%, with a mean DMFT score of 2.82. Periodontal health showed unsatisfactory indicators such as mobile teeth, poor gingival health, high plaque scores, and the presence of halitosis. Conclusion: This descriptive study aimed to provide baseline data on the oral health status of special needs students in Kumasi, addressing the lack of knowledge in this area. It highlighted the importance of dental care in maintaining good oral health and overall well-being in individuals with special needs. Coordinated efforts by dental professionals are needed to provide dental health education and preventive interventions for these children. 展开更多

Low income is the main problem of millions of farmers who are cultivating 4.81 million hectares in the Philippines. This problem is attributed to challenges specifically low yield, low quality of produce, and significant post-harvest losses, particularly in a resource-scarce setting. This study aimed to help increase the farmers’ income in selected towns of Nueva Ecija through the promotion and use of special purpose rice production technology. Twenty (20) farmer-cooperators in three towns of Nueva Ecija were selected to demonstrate the production technology covering a total area of 4.75 hectares during the dry season, and 3.3 hectares during the wet season, both in 2023. Extension modalities such as training, techno-demo establishment, information material and technical assistance provision, and market linkage were undertaken to enhance their knowledge, attitude, and skills on special rice production and enterprise. The study utilized the descriptive quantitative method wherein the data were gathered through surveys, specifically personal interviews. Results showed that 70% of the farmer-cooperators were male and 60% were living below the poverty threshold. The farmers were 53 years old on average and engaged in farming as their primary source of income. The average yield of special purpose rice particularly the CLS-2 variety was higher (6.46 MT/ha and 6.22 MT/ha during dry and wet seasons, respectively) than that of inbred or non-special rice. The income per hectare from special purpose rice production per hectare was Php 75,420.00, which is higher than that of regular rice at Php 29,389.00, giving a higher benefit of Php 46,031.00. The technology adopters and area planted increased (from 6 to 9 and from 1.4 hectares to 2.75 hectares, respectively) in Licab, Nueva Ecija. The opposite was true in Sto. Domingo and Guimba, Nueva Ecija where farmers were discouraged by the marketing issues that arose. 展开更多

The functional specialization in export of a country(and its sectors)in different activities,such as fabrication,R&D,management and marketing,is crucial to its governance and control on the value chains,which magnifies the shortage of the existing aggregate value added studies on our understanding of global value chains(GVCs).Considering production fragmentation at both the spatial and functional levels,this paper defines the modified functional specialization indicators at the national and sectoral levels from the forward linkage(rather than backward linkage).Based on the World Input-Output Database together with the newly compiled Labor Occupations Database,this paper re-estimates and analyzes the functional specialization and changes in China and major developed economies’exports.The results show that China’s export is mainly specialized in fabrication activity,which is among the world leading level,while it is weak in headquarter activities(especially R&D and management),which is almost locked at the lowest level in the world and could not pose an export threat to the developed economies.China’s manufacturing basically follows the functional development path of“relying on fabrication,entering market,targeting management and R&D”,featuring the coexistence of“strong”fabrication and“weak”management and R&D.The fabrication specialization of the typical processing sector“electronic and optical equipment”has reached the international leading level.The level of functional specialization of China’s service industry is generally lower than that of manufacturing and generally lags behind in the world,indicating that China still has a long way to go before becoming a major power of service in the world.Finally,this paper proposes policy implications and further researches that can be extended. 展开更多

Metrological analysis shows that any clock in inertial motion in infinite space shall not have time dilation, due to relativity of such motion in such space. On the other hand, atomic clock in inertial motion in finite space shall exhibit time dilation, due to alteration of momentum of clock-defining particle caused by nonzero curvature of trajectory of such motion in such space. Therefore, time dilation experiment of atomic clock in inertial motion in physical space provides a direct and decisive way of determining geometry of physical space in real-time. Phenomenon of time dilation of atomic clock in inertial motion in physical space has long been observed and confirmed experimentally. Therefore, extent of physical space has to be finite, consistent with result of high precision experiment of free particle in high-speed motion conducted a decade ago.Keywords Geometry of Physical Space, Time Dilation, Atomic Clock, Special Relativity Theory. 展开更多

A natural extension of the Lorentz transformation to its complex version was constructed together with a parallel extension of the Minkowski M<sup>4</sup> model for special relativity (SR) to complex C<sup>4</sup> space-time. As the [signed] absolute values of complex coordinates of the underlying motion’s characterization in C<sup>4</sup> one obtains a Newtonian-like type of motion whereas as the real parts of the complex motion’s description and of the complex Lorentz transformation, all the SR theory as modeled by M<sup>4</sup> real space-time can be recovered. This means all the SR theory is preserved in the real subspace M<sup>4</sup> of the space-time C<sup>4</sup> while becoming simpler and clearer in the new complex model’s framework. Since velocities in the complex model can be determined geometrically, with no primary use of time, time turns out to be definable within the equivalent theory of the reduced complex C<sup>4</sup> model to the C<sup>3</sup> “para-space” model. That procedure allows us to separate time from the (para)space and consider all the SR theory as a theory of C<sup>3</sup> alone. On the other hand, the complex time defined within the C<sup>3</sup> theory is interpreted and modeled by the single separate C<sup>1</sup> complex plane. The possibility for application of the C<sup>3</sup> model to quantum mechanics is suggested. As such, the model C<sup>3</sup> seems to have unifying abilities for application to different physical theories. 展开更多
