Semen analysis results （volume, sperm count, motility, and morphology） were the primary outcomes. An electronic search to collect the data was conducted using the Medline/PubMed, SJU discover, and Google Scholar databases. We searched articles published from 2010 to August 2015, i.e., after the publication of the 2010 WHO manual. We included only those studies that reported the actual semen parameters of adult infertile men diagnosed with clinical varicocele and contained a control group of either fertile men or normozoospermic men who were not diagnosed with varicocele. Ten studies were included in the meta-analysis, involving 1232 men. Varicocele was associated with reduced sperm count （mean difference： -44.48 x 106 ml-1; 95% Ch -61.45, -27.51 x 106 ml-1; P〈 0.001）, motility （mean difference： -26.67%; 95% Ch -34.27, -19.08; P 〈 0.001）, and morphology （mean difference： -19.68%; 95% Ch -29.28, -10.07; P 〈 0.001） but not semen volume （mean difference： -0.23 ml; 95% CI： -0.64, 0.17）. Subgroup analyses indicated that the magnitude of effect was influenced by control subtype but not WHO laboratory manual edition used for semen assessment. We conclude that varicocele is a significant risk factor that negatively affects semen quality, but the observed pooled effect size on semen parameters does not seem to be affected by the WHO laboratory manual edition. Given most of the studies published after 2010 still utilized the 1999 manual for semen analysis, further research is required to fully understand the clinical implication of the 2010 WHO laboratory manual on the association between varicocele and semen parameters.展开更多

And a framework for ODSS is designed. The framework has three components： infrastructure, decision-making process and decision execution process. Infrastructure is responsible to transfer data and information. Decision-making process is the ODSS＇s soul to support decision-making. Decision execution process is to evaluate and execute decision results derived from decision-making process. The framework presents a kind of logic architecture. An example is given to verify and analyze the framework. The analysis shows that the framework has practical values, and has also reference values for understanding ODSS and for theoretical studies.展开更多

Based on the designed system model for TV media organization structure, the relations among the main factors of the system constitution, missions, organizing decision entity, and carrying bodies were analyzed. By means of applying multi-objective decision method and complex control system theory, and combining the integration model of TV media organization structure, the basic model was concluded and the corresponding parameters were designed. The current organization process of TV media is analyzed by this model, which comes to the adaptability appearance with different parameters. The results indicate that the model can estimate current TV media organization structure for the chain appearance of communications and the correlation between platforms and policy-making agencies.展开更多
Spatial organization of multiple plant species that appears as a non-random distribution of vegetative patches is one of the mostly observed spatial patterns in arid ecosystems. Yet understanding of ecological process...Spatial organization of multiple plant species that appears as a non-random distribution of vegetative patches is one of the mostly observed spatial patterns in arid ecosystems. Yet understanding of ecological processes allowing this spatial pattern to emerge through interspecific interactions is still lacking. With a proposed conceptual model involving interspecific trade-offs between species competitive ability and colonization ability, we have argued that within patch abundance dynamics regulated by the mechanisms of competition are strongly influenced by the between patches colonization dynamics that are maintained via this trade-offs and it holds a positive, intraspecific occupancy-abundance relationship, in which increased patch occupancy increases species density within inhabiting patches. In a constant environment, while local abundance dynamics approach toward a stable equilibrium point, a fixed spatial arrangement of species can be retained through this coupled dynamics. However, in fluctuating environments where existence of such stable equilibriums is highly uncertain, it may involve continuous transitions from one community state to another as species re-organized themselves over space through the rapid changes in local species abundances. While some of the inhabiting patches are destroyed exogenously or endogenously, or species responses to increasing environmental fluctuations vary increasingly with time, discontinuous transitions into an abrupt, irreversible state of the community dynamics may occur, as with this effect the inherent positive relationship between occupancy and abundance of species is no longer maintained.展开更多

Facing the increasing trend of cancer incidence and mortality, China issued and implemented ＂three-early（early prevention, early diagnosis and early treatment）＂ national cancer prevention plan. As the main body and dependence of social governance, non-governmental organizations（NGOs） take over the role of government in the field of cancer prevention and treatment. American Cancer Society（ACS） made a research on cancer NGOs and civil society in cancer control and found that cancer NGOs in developing countries mobilize civil society to work together and advocate governments in their countries to develop policies to address the growing cancer burden. Union for International Cancer Control（UICC）, Cancer Council Australia（CCA）, and Malaysian cancer NGOs are the representatives of cancer NGOs in promoting cancer control. Selecting Chinese Anti-Cancer Association（CACA） as an example in China, this article is to investigate how NGOs undertake systematic cancer prevention work in China. By conducting real case study, we found that, as a NGO, CACA plays a significant role in intensifying the leading role of government in cancer control, optimizing cancer outcomes, decreasing cancer incidence and mortality rates and improving public health.展开更多

Companies are not limited to physical locatio ns for providing products and services. Networked information systems are allowi ng companies to coordinate their geographically distributed capabilities as virt ual organizations. In order for organizations to succeed, they must be able to r espond with agility in a geographically dispersed environment. The core for a vi rtual organization to increase the utilization rate of resources to the maxi mum and to make full use of the transient market opportunities lies in how to br ing the potential of information technology into play. Based on the philosophy o f agile manufacturing, this paper analyses the basic concepts and connotation of Virtual Organization Information systems(VOIS). VOIS is an information system composed of some independent information subsystems that are autonomous, collab orative and belong to umpty organizations respectively. VOIS support the operati on of virtual organization, and automate the information flow across organizatio nal boundaries. Such systems have capabilities as rapid construction, quick oper ation, and agile reengineering and swift adaptability. Differences between VOIS and traditional enterprise information systems are analyzed. On the basis of ana lyzing the structure of VOIS, an abstract hierarchical structure of VOIS is prop osed using object-oriented method. Reengineering ideology and methods of VOIS a re also explored in light of the three layers structure.展开更多

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

Because a shortage of organ donation is a serious social issue in Japan, various solutions to the issue have been considered. Although it was believed that the most critical factor in the organ shortage was the absence of a well-established social system, no prior studies attempted to analyze the issue from the perspective of the mechanisms and organizational behaviors. To identify common success factors of increasing organ donation, we conducted a qualitative survey in 5 countries promoting organ donations on a national level and increasing the number of organ donations. We found several important common factors: 1) to change from an explicit consent system to a presumed consent system with establishment of an appropriate in-hospital system, 2) to increase the level of job satisfaction of healthcare professionals and help them generating better results, 3) to demonstrate managements’ leadership for all staff to realize the importance of organ donations, 4) to establish an environment where medical professionals engaged in organ donations can appreciate autonomous working styles, the recognition of the importance of the work. It is suggested that these successful factors are introduced into Japan with long-, mid-term strategy to enhance organ donation.展开更多

文摘Advanced oxidation processes(AOPs)that utilize the highly potent hydroxyl radical(·OH)are a cornerstone of modern environmental remediation.Among these,the Fenton reaction is renowned for its effectiveness[1].However,its practical application has been persistently hampered by two fundamental constraints:a strict reliance on acidic conditions(typically pH 2-4)and the need to be continuously supplied,costly externally generated hydrogen peroxide(H_(2)O_(2))[2-4].
文摘This study investigated the effects of varicocele on semen parameters in infertile men based on the new 2010 World Health Organization laboratory manual for the examination of human semen. Semen analysis results （volume, sperm count, motility, and morphology） were the primary outcomes. An electronic search to collect the data was conducted using the Medline/PubMed, SJU discover, and Google Scholar databases. We searched articles published from 2010 to August 2015, i.e., after the publication of the 2010 WHO manual. We included only those studies that reported the actual semen parameters of adult infertile men diagnosed with clinical varicocele and contained a control group of either fertile men or normozoospermic men who were not diagnosed with varicocele. Ten studies were included in the meta-analysis, involving 1232 men. Varicocele was associated with reduced sperm count （mean difference： -44.48 x 106 ml-1; 95% Ch -61.45, -27.51 x 106 ml-1; P〈 0.001）, motility （mean difference： -26.67%; 95% Ch -34.27, -19.08; P 〈 0.001）, and morphology （mean difference： -19.68%; 95% Ch -29.28, -10.07; P 〈 0.001） but not semen volume （mean difference： -0.23 ml; 95% CI： -0.64, 0.17）. Subgroup analyses indicated that the magnitude of effect was influenced by control subtype but not WHO laboratory manual edition used for semen assessment. We conclude that varicocele is a significant risk factor that negatively affects semen quality, but the observed pooled effect size on semen parameters does not seem to be affected by the WHO laboratory manual edition. Given most of the studies published after 2010 still utilized the 1999 manual for semen analysis, further research is required to fully understand the clinical implication of the 2010 WHO laboratory manual on the association between varicocele and semen parameters.
文摘The classification of central nervous system(CNS)glioma went through a sequence of developments,between 2006 and 2021,started with only histological approach then has been aided with a major emphasis on molecular signatures in the 4^(th) and 5^(th) editions of the World Health Organization(WHO).The recent reformation in the 5th edition of the WHO classification has focused more on the molecularly defined entities with better characterized natural histories as well as new tumor types and subtypes in the adult and pediatric populations.These new subclassified entities have been incorporated in the 5^(th) edition after the continuous exploration of new genomic,epigenomic and transcriptomic discovery.Indeed,the current guidelines of 2021 WHO classification of CNS tumors and European Association of Neuro-Oncology(EANO)exploited the molecular signatures in the diagnostic approach of CNS gliomas.Our current review presents a practical diagnostic approach for diffuse CNS gliomas and circumscribed astrocytomas using histomolecular criteria adopted by the recent WHO classification.We also describe the treatment strategies for these tumors based on EANO guidelines.

文摘The concept of organization decision support system （ODSS） is defined according to practical applications and novel understanding. And a framework for ODSS is designed. The framework has three components： infrastructure, decision-making process and decision execution process. Infrastructure is responsible to transfer data and information. Decision-making process is the ODSS＇s soul to support decision-making. Decision execution process is to evaluate and execute decision results derived from decision-making process. The framework presents a kind of logic architecture. An example is given to verify and analyze the framework. The analysis shows that the framework has practical values, and has also reference values for understanding ODSS and for theoretical studies.
文摘To resolve the control adaptability problem of TV media in complex competitive environment, a control system model of TV media organization structure was designed. Based on the designed system model for TV media organization structure, the relations among the main factors of the system constitution, missions, organizing decision entity, and carrying bodies were analyzed. By means of applying multi-objective decision method and complex control system theory, and combining the integration model of TV media organization structure, the basic model was concluded and the corresponding parameters were designed. The current organization process of TV media is analyzed by this model, which comes to the adaptability appearance with different parameters. The results indicate that the model can estimate current TV media organization structure for the chain appearance of communications and the correlation between platforms and policy-making agencies.

文摘Spatial organization of multiple plant species that appears as a non-random distribution of vegetative patches is one of the mostly observed spatial patterns in arid ecosystems. Yet understanding of ecological processes allowing this spatial pattern to emerge through interspecific interactions is still lacking. With a proposed conceptual model involving interspecific trade-offs between species competitive ability and colonization ability, we have argued that within patch abundance dynamics regulated by the mechanisms of competition are strongly influenced by the between patches colonization dynamics that are maintained via this trade-offs and it holds a positive, intraspecific occupancy-abundance relationship, in which increased patch occupancy increases species density within inhabiting patches. In a constant environment, while local abundance dynamics approach toward a stable equilibrium point, a fixed spatial arrangement of species can be retained through this coupled dynamics. However, in fluctuating environments where existence of such stable equilibriums is highly uncertain, it may involve continuous transitions from one community state to another as species re-organized themselves over space through the rapid changes in local species abundances. While some of the inhabiting patches are destroyed exogenously or endogenously, or species responses to increasing environmental fluctuations vary increasingly with time, discontinuous transitions into an abrupt, irreversible state of the community dynamics may occur, as with this effect the inherent positive relationship between occupancy and abundance of species is no longer maintained.
文摘Cancer has become the first leading cause of death in the world, particularly in low- and middle-income countries. Facing the increasing trend of cancer incidence and mortality, China issued and implemented ＂three-early（early prevention, early diagnosis and early treatment）＂ national cancer prevention plan. As the main body and dependence of social governance, non-governmental organizations（NGOs） take over the role of government in the field of cancer prevention and treatment. American Cancer Society（ACS） made a research on cancer NGOs and civil society in cancer control and found that cancer NGOs in developing countries mobilize civil society to work together and advocate governments in their countries to develop policies to address the growing cancer burden. Union for International Cancer Control（UICC）, Cancer Council Australia（CCA）, and Malaysian cancer NGOs are the representatives of cancer NGOs in promoting cancer control. Selecting Chinese Anti-Cancer Association（CACA） as an example in China, this article is to investigate how NGOs undertake systematic cancer prevention work in China. By conducting real case study, we found that, as a NGO, CACA plays a significant role in intensifying the leading role of government in cancer control, optimizing cancer outcomes, decreasing cancer incidence and mortality rates and improving public health.
文摘It is now possible to organize globally while worki ng locally: Information technologies like e-mail, the Internet, and video confere ncing to the desktop permit tight coordination of geographically dispersed worke rs across time zones and cultures. Companies are not limited to physical locatio ns for providing products and services. Networked information systems are allowi ng companies to coordinate their geographically distributed capabilities as virt ual organizations. In order for organizations to succeed, they must be able to r espond with agility in a geographically dispersed environment. The core for a vi rtual organization to increase the utilization rate of resources to the maxi mum and to make full use of the transient market opportunities lies in how to br ing the potential of information technology into play. Based on the philosophy o f agile manufacturing, this paper analyses the basic concepts and connotation of Virtual Organization Information systems(VOIS). VOIS is an information system composed of some independent information subsystems that are autonomous, collab orative and belong to umpty organizations respectively. VOIS support the operati on of virtual organization, and automate the information flow across organizatio nal boundaries. Such systems have capabilities as rapid construction, quick oper ation, and agile reengineering and swift adaptability. Differences between VOIS and traditional enterprise information systems are analyzed. On the basis of ana lyzing the structure of VOIS, an abstract hierarchical structure of VOIS is prop osed using object-oriented method. Reengineering ideology and methods of VOIS a re also explored in light of the three layers structure.
文摘Based on the theory of ecological organization,this paper analyzes the operation mechanism of chemical industry park(CIP)ecosystem by means of dynamic simulation.The research shows that the CIP ecosystem is a complex ecological system whose operation mechanism includes two levels,namely individual enterprises and ecosystem.At the level of individual enterprise,there are competition,symbiosis,invasion and other interactions between enterprises in the CIP ecosystem.Through the pre-determined judgment of the competition effect coefficient and the symbiosis effect coefficient,we calculate how the enterprises influence each other,and then generate their respective operation paths,andfinally realize the long-term balance of the system.At the level of ecosystem,the CIP ecosystem makes self-organizing and self-adaptive adjustments and changes due to the changes of the exter-nal environment in policy,manpower,technology,capital,market,etc.,thus reaching the equilibrium state of coordinated operation and stable symbiosis with the external environment.

文摘On the basis of expounding the necessity of evaluation index system of farmers'cooperative economic organization,the three first level indexes including organization development index,member development index and social development index and 13 second level indexes including aggregate capital of cooperative organization,annual profit share of cooperative organization,annual total income of cooperative organization,etc.,are established according to the principles of Systematics and the methods of Statistics and Quantitative economics.By using the analytical hierarchy process,the weight of each index is tested and the operation result and evaluation mode is established,as well as the index standard value and comprehensive value.As for the result of the evaluation,it is suggested that the government should support the farmers'cooperative organizations in hierarchy and targeted way according to local conditions.Though the construction of index system and comprehensive score,the government should establish the entry and exit mechanism of farmers'cooperative organizations to reasonably guild the rapid development of cooperators.
文摘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.
文摘The Tanzania Zambia Railway stretches 1,860 kilometers from the East African Indian Ocean port of Dar es Salaam in Tanzania to New Kapiri-Mposhi in land locked Zambia.It is defined as a bi-national organization as opposed to either transnational or multinational because it is jointly owned and managed by the Governments of Tanzania and Zambia.Its construction was made possible by Chinese interest-free loan to the two Governments.Few development projects in Africa have been charged with as much political and ideological dynamite as Tanzania Zambia Railway.To the Western powers,angry that the Chinese had entered territory which they considered their own preserve,it was a Red Railway intended to thrust communism into the very heart of Africa.For the white regimes in Southern Africa,grimly attempting to hold back demands for majority rule,it was seen as Africa’s Ho Chi Minh Trail,carrying guerrilla further,armed with Chinese thoughts and weapons to the banks of the Zambezi River.The Chinese regarded the project as a Friendship Route to strengthen the new African states against the forces of imperialism and for Tanzania and Zambia it was a Freedom Railway,which should prove an instrument in increasing their independence.These reactions underpin not only the complexity of the establishment and management of a bi-national organization but also present challenges to the two national trade unions on how best they can represent their members.Industrial relations literature has cited differences in countries’historical,social,political,economic,and ideological background as the main obstacles in the development of collective bargaining machinery in transnational or multinational organizations.A study in Tanzania Zambia Railway Authority has attempted to develop an integrated bi-national collective bargaining machinery whose collective agreements are likely to be legally enforceable in their respective countries.This paper explores the development of trade unions in both Tanzania and Zambia which can be divided in three phases:first,the construction phase;second,the consolidation phase;and the third and final phase,trade union liberalization and political pluralism which covers the development of a bi national collective bargaining model with its Joint Industrial Council structure and negotiation procedures.The paper compares and contrasts trade union development in the two contracting states and critically examines how each phase has influenced trade union development.It provides a brief historical outline of collective bargaining process and spells out advantages and limitations of bi-national collective bargaining machinery.The paper concludes by observing that one of the main objectives of regional groupings is economic integration and suggests that integrated collective bargaining machinery be adopted as an ideal industrial relations model for regional groupings such as the African Union(AU),Southern African Development Community(SADC),Common Market for Eastern and Southern Africa(COMESA),Economic Community for West African States(ECOWAS),Eastern African Community,and other regional groupings around the world since it localizes industrial relations function in general and collective bargaining in particular.
文摘Deceased organ donation is much less prominent in Japan than it is in Western and other Asian countries. Because a shortage of organ donation is a serious social issue in Japan, various solutions to the issue have been considered. Although it was believed that the most critical factor in the organ shortage was the absence of a well-established social system, no prior studies attempted to analyze the issue from the perspective of the mechanisms and organizational behaviors. To identify common success factors of increasing organ donation, we conducted a qualitative survey in 5 countries promoting organ donations on a national level and increasing the number of organ donations. We found several important common factors: 1) to change from an explicit consent system to a presumed consent system with establishment of an appropriate in-hospital system, 2) to increase the level of job satisfaction of healthcare professionals and help them generating better results, 3) to demonstrate managements’ leadership for all staff to realize the importance of organ donations, 4) to establish an environment where medical professionals engaged in organ donations can appreciate autonomous working styles, the recognition of the importance of the work. It is suggested that these successful factors are introduced into Japan with long-, mid-term strategy to enhance organ donation.
