Soil organic matter(SOM)monitoring using remote sensing is critical for effective land resource management and environmental protection.Mapping SOM in areas where saline and black soils are intertwined,with complex soil types and significant environmental variability,remains a challenging task.This study integrated prior knowledge and classified Jilin Province,China,into saline-alkali and black soil areas.All available Sentinel-2 images from 2019 to 2023 during the bare soil period(April to July)were collected,and the images were categorized into three time windows:day of year(DOY)90-120,DOY 120-150,and DOY 150-180.The potentials of these time windows,spectral indices(salinity index and vegetation moisture index),environmental variables(topography and climate),and local regression models for SOM mapping in the saline-black soil transition areas were then systematically evaluated.The results revealed four key findings:(1)the optimal time window for SOM mapping in both the saline-alkali area and black soil area was DOY 90-120;(2)including the salinity index improved SOM mapping accuracy in the saline-alkali area but reduced it in the black soil area,whereas the vegetation moisture index enhanced accuracy in both areas;(3)incorporating environmental variables improved the SOM mapping accuracy in all areas,with topographic variables being more influential in the black soil area and climatic variables being more significant in the saline-alkali area;and(4)local regression models based on the saline-alkali area and black soil area outperformed the global regression model in terms of SOM mapping accuracy,although they exhibited higher uncertainty.This study demonstrates that the integration of prior knowledge and multitemporal remote sensing images significantly enhance SOM mapping accuracy in areas where saline and black soils intersect,thus providing a scientific foundation for the precise management and protection of areas with different soil types. 展开更多

This paper examines the role of transformational leadership in transforming an organization into a knowledge based, then into learning organization so that it becomes an innovative company. Important features of the leader such and ability to assist in developing and accommodating the implementation of knowledge management programs, learning organization concepts and innovation protocols are discussed in this paper. This paper demonstrates that shifting the organization to become a knowledge based and then to be learning organization and finally to become innovative company could involve some unique attributes of a transformation leadership. In that regards, the paper also demonstrates that organizations need first to create, capture, transfer, and mobilize knowledge before it can be used for learning and then for innovation. The paper will present a method of a studying how successful innovation leaders of companies could found themselves acting in three roles namely： knowledge leader, learning leader and then innovation leader. 展开更多

The complex and flexible environment that organizations tace now is never seen betore, and the ability of radical transforming is becoming absolutely necessary to an organization. The organization transformation process is also anatomized here by means of ＂knowledge convening ＆ fermenting model＂. In the knowledge-based economy times, organization transformation must focus on the knowledge management and the acquirement of the knowledge employees. Through the ＂knowledge convening ＆ fermenting model＂, we put forwards the system thinking way of organization transformation. The key point of organization transformation is reconsidering, and the thinking of the knowledge carriers obtaining is widened by the definition of ＂knowledge matrix＂, so the leader should do well in the reconsidering during the process of the organization transformation, confirming the organization＇s development direction, searching for the knowledge matrix, meanwhile, he also should be good at the creation of the favorable knowledge innovation environment for knowledge employees. 展开更多

This paper templet is copyright by Global Conference on Business and Social Science organized by Global Academy of Training&Research(GATR)Enterprise.Intellectual capital and knowledge are the most important assets of most organizations to ensure that determined or intended strategies can be implemented.The resource-based view of the firm considers the firm as a bundle of tangible resources,intangible resources,and organisational capabilities.An effective IC refers to the critical issues of organisational adaptation,survival and competence in the face of discontinuous environmental change.KM is essential for retaining employees’knowledge within a firm by using appropriate technology and tools to capture and store the knowledge residing in the minds of its employees,so it can be easily shared and reused.There is a growing realisation of the importance of the development and understanding of theory for both Intellectual Capital and Knowledge Management in relation to guide the successful development of Knowledge Management Organisations.This study is fundamental because it will provide the whole picture about the different levels of knowledge;individual,group and organizational,which express internal knowledge(formal and informal knowledge)and external knowledge such as customers and suppliers.The aim of this study is addressed some of the gaps in Intellectual Capital literature.It is necessary to investigate the interactions between IC components in Knowledge management organizations,which include human capital(HC),Organizational capital(OC),and Relational capital(RC).This is important in order to discover the extent to which these factors work together to achieve a network’s knowledge management in organization. 展开更多

This article describes a valid and current research area, which is the formation of organizational learning ability, perceived as a condition necessary for the survival and development of modern organizations. It refers to the issue of organic organizational structure as a factor shaping this ability. Many researchers emphasized that the organizational structure plays a key role in determining the processes of organizational learning. However, only in recent years, these views have been verified empirically---demonstrating the importance of organic structures in this area. Therefore, determination of what may contribute to the development of organic structural solutions in the context of developing learning capacity of the company appears to be a significant research problem. This article discusses what is the organic organizational structure role in shaping the learning ability of organization. It was empirically verified, using confirmation factor analysis, that among other factors organic structure determines organizational learning capability （OLC）. Next part of article describes information technology （IT） and knowledge management （KM） as two important factors influencing structure reorganization and facilitating introduction of organic-type structure in organization. Discussion concerning the problem of their influence on various organizational structure dimensions is included. After that, research results are presented. First part of these researches concerns IT and KM influence on organizational structure and provides conclusions based on correlation and stepwise regression analysis. The empirical results show that IT and KM are two important factors influencing structure reorganization and facilitating introduction of organic-type structure in organization. Research has shown that these factors are complementary in terms of their impact on the organizational structure （they have a statistically significant impact on various structural dimensions）. Therefore, IT and KM may be considered as intermediate factors influencing OLC and should be closely observed in those organizations, which are trying to enhance their learning capability. 展开更多

Information Technology （IT） consolidates as an essential element to support the business strategies to survive and rapidly adapts to changes in the competitive environment. This paper examines the impact of the use of information systems （IS） and strategic organization knowledge （SOK） on firm performance in 150 Brazilian companies. The study uses partial least squares structural equation modeling （PLS-SEM） and establishes models to express the relationship among the constructs examined. The study identifies that the direct influence of 1S use on performance is moderately significant. However, when mediated by orientation strategy, the total effect of IS use on firm performance is demonstrated to be highly significant. The model explains 54% of the variability of firm performance and confirms IS use as a fundamental resource to support strategic business processes. 展开更多

BACKGROUND The most important factors affecting attitudes on organ donation are socioeconomic, educational, cultural, and religious factors in many countries.AIM To evaluate the attitudes, awareness, and knowledge levels of the Turkish adult population toward organ donation.METHODS This nationwide study surveyed 3000 adults(≥ 18 years) in Turkey. To ensure a representative sample, the Nomenclature of Territorial Units for Statistics-Ⅱ(modified for Turkey) was used. Turkey was divided into 26 regions based on social, economic, and geographic criteria as identified by the Turkish Statistical Institute. A stratified sampling method was used with an even distribution of adults across cities and towns based on population data. Data were collected by the PRP Research and Consultancy Company using computer-assisted personal interviews.RESULTS Out of 3000 individuals represented in the study population, 1465(48.8%) were male and 1535(51.2%) female. The results showed that most participants were under 45 years(59.0%) and married(72.1%), some had a bachelor’s degree or higher(21.9%), and very few(1.5%) had any direct experience with organ transplantation-whether in the family, or a family member on a transplantation waiting list. Most of the study population(88.3%) had not considered donating an organ, however, most(87.9%) said that they would accept an organ from a donor if they needed one. Among the individuals surveyed, 67% were willing to donate an organ to a close relative, while 26.8% would donate an organ to an unrelated person. Only 47.2% said they had adequate information about brain death, and 85.2% refused to consent to donating organs of family members declared brain dead. Only 33.9% thought they had adequate information about organ donation. The main source of information was the television. The two main reasons for refusing organ donation were that it was too soon to think about organ donation and the importance of retaining the integrity of the dead person’s body.CONCLUSION This study showed that Turkey’s adult population has inadequate knowledge about organ donation. The study advocates for public education programs to increase awareness among the general population about legislation related to organ donation. 展开更多

BACKGROUND Organ donation is a critical issue that is receiving greater attention worldwide.In Jordan,the public’s knowledge about and attitudes toward organ donation play a significant role in the availability of organs for transplantation.AIM To assess the public knowledge about and attitudes toward organ donation in Jordan.METHODS A cross-sectional design was used to collect data from 396 Jordanian citizens via an online self-reported questionnaire.RESULTS Overall,396 participants were recruited.Of the entire sample,93.9%of the participants had heard about and had sufficient knowledge about organ donation but they had limited knowledge about brain death.The most common source of information about organ donation was social media networks.Females were found to score significantly higher than males for attitude.Those who had thought about organ donation or registered their names to donate scored signi-ficantly higher in terms of attitudes to donation than their counterparts who had not.The most common reasons for limited organ donation practices in Jordan were a lack of awareness programs and insufficient knowledge in society.CONCLUSION Greater public understanding of organ donation appears to be associated with more positive attitudes toward organ donation.Most participants responded positively regarding their attitude toward organ donation as they believed that this action could give another person a chance to live.Moreover,most agreed that they would donate their organs after their death.Otherwise,the participants had limited general knowledge about brain death,and most had not registered their names to donate their organs.These findings indicate the need for public awareness campaigns and educational programs to encourage more people to become organ donors. 展开更多

Purpose: Radiotherapy is a widely accepted standard of care for early-stage prostate cancer, and it is believed that the plan quality and treatment outcome are associated with contour accuracy of both the target and organs-at-risk (OAR). The purposes of this study are to 1) assess geometric and dosimetric uncertainties due to inter-observer contour variabilities and 2) evaluate the effectiveness of geometric indicators to predict target dosimetry in prostate radiotherapy. Methods: Twenty prostate patients were selected for this retrospective study. Five experienced clinicians created unique structure sets containing prostate, seminal vesicles, bladder, and rectum for each patient. A fully automated script and knowledge-based planning routine were utilized to create standardized and unbiased plans that could be used to evaluate changes in isodose distributions due to inter-observer variability in structure segmentation. Plans were created on a “gold-standard” structure set, as well as on each of the user-defined structure sets. Results: Inter-observer variability of contours during structure segmentation was very low for clearly defined organs such as the bladder but increased for organs without well-defined borders (prostate, seminal vesicles, and rectum). For plans generated with the user-defined structure sets, strong/moderate correlations were observed between the geometric indicators for target structure agreement and target coverage for both low-risk and intermediate-risk patient groups, while OAR indicators showed no correlation to final dosimetry. Conclusions: Target delineation is crucial in order to maintain adequate dosimetric coverage regardless of the associated inter-observer uncertainties in OAR contours that had a limited impact upon final dosimetry. 展开更多

As innovation and technological change have become increasingly important for the competitiveness and sustainable growth of firms,cooperative innovation is now crucial for traditional industries in the context of globalization.This paper proposes a framework for analyzing the spatial pattern of cooperative innovation for traditional industries in developing countries.Based on in-depth interviews with 35 firms in the oil equipment manufacturing industry in Dongying City,China,this study argues that different firms in the innovation pyramid have various innovation activity preferences and spatial patterns.Firms with high innovation abilities tend to cooperate with various partners that are geographically dispersed and continuously expanding,while firms with inferior abilities usually cooperate with nearby fixed partners.Due to the differences in innovation environment and actor locations,firms tend to make different choices regarding innovation types and models,which highlight the importance of personnel training and basic scientific research at the global scale and practical product research and development at the national scale.Additionally,talent flow is the most important way to realize relationships for firm innovation activity. 展开更多

Purpose:This study aims to construct an ontology to model the semantics of social media streams,in particular,trending topics and public issues.Design/methodology/approach:Our knowledge base included 10 public events and topics from Weibo respectively,which were collected through keyword search and a crawler program.We used a semi-automatic approach to model and annotate the semantics in social media,and adapted the multi-layered ontology to refine the design based on previous researches,then we used named entity recognition(NER) to extract entities to instantiate the ontology.Relationships were extracted based on co-occurrence measures.Finally,we manually conducted post-filtering evaluation and edited the extracted entities and relationships.Findings:An initial assessment demonstrated that our multi-layered ontology supports various types of queries and analyses in the public issue knowledge base(PIKB),which can serve as an effective tool to query,understand and trace public issues.Research limitations:Manual involvement cannot meet the requirements for challenges of sustainable developments.Since the relationships extracted are fully based on the co-occurrence of entities,rich semantic relationships,such as how much the key players have been involved,could not be fully reflected.Besides,the user evaluation is necessary for further ontology assessment.Practical implications:The PIKB can be used by regular Web users and policy makers to query,understand,and make sense of public events and topics.The methodology and reusable ontology model are useful for institutions that are interested in making use of the social media data.Originality/value:In this study,a multi-layered ontology is applied to model the evolving semantics of public events and trending topics in social media,and the semi-automatic approach could make it possible to extract entities and relationships from large amount of unstructured short texts of user generated content(UGC) from social media. 展开更多

The authors will show that serendipity is capability method of finding potential needs and/or new markets. In economic society, potential needs and/or new markets are only partially exposed, such as an iceberg. Serendipity is a capability that can expose the potential hidden part through accidental opportunity. Something more concrete can be formed from the exposed parts. The authors describe cases that demonstrate the usefulness of serendipity. In one case, a high-tech start-up had intended to use medical electronic equipment and/or industrial electronic equipment as the first application of their core technology. In these markets, they were competing with established major companies, so this start-up had difficulty entering these markets. However, a specific distributor found potential needs that were met by the start-up＇s products, and has created a new market by combining their core technology with social needs. The authors define serendipity capability by analyzing this case example and argue that serendipity can contribute to finding opportunities and solving social issues. 展开更多
