Objective: To know about the current situation of hypertension in some areas of Hubei Province and analyze the influencing factors. Methods: According to the principle of Stratified sampling, we conducted health examination and questionnaire survey for 1500 residents over the age of 18 at observation point of chronic noninfectious diseases at 10 sub-districts (towns) of Wuhan City, Jingzhou City, Huanggang City, Shiyan City, which used descriptive statistics and logistics to regressively analyze Current situation of hypertension and its influencing factors of residents. Results: Prevalence of hypertension of rural and urban residents over 18 is 27.44% in Hubei province. There are many differences among prevalence of hypertension of male and female, distribution of BMI of rural and urban residents and prevalence of hypertension and so on, and it has statistical significance (P-value < 0.05 averagely);logistic regressive analysis result shows that different age, gender, education level, dieting habits (high salt and high oil), family per capita monthly income, BMI have statistical significance on the prevalence of hypertension in urban and rural residents of Hubei Province. Conclusions: The prevalence of hypertension in the residents of five cities and prefectures in Hubei Province is on the trend of rising in ladder form and at a much earlier age. The health education, monitoring and intervention of chronic diseases need to be widely carried out, with emphasis on the intervention of the residents’ eating habits of high salt and oil, smoking, drinking and other bad lifestyle. 展开更多

The United Nations Framework Convention on Climate Change(UNFCCC)has established a climate governance mechanism with intergovernmental negotiations among sovereign states as the core.After nearly 30 years,progress in combating climate change has remained very modest compared with the numerous challenges raised.The global climate governance has entered a new era,such that incorporating other factors into the governance process is timely.Therefore,the study emphasizes technological innovation and business actors in climate governance after the Paris Agreement.Technological innovation can provide effective solutions for combating climate change and has been a crucial driving force in climate governance's evolution.Business actors are significant because they are actual implementers of technological innovation and can apply different types of power and influence on climate governance processes at various levels.In summary,business actors,as well as technological innovation in line with governments and the UNFCCC governance frameworks,create a new potential for climate governance in the new era. 展开更多

TheRussia-Ukrainecrisiswas araremilitary crisis between European powers after the end of the Cold War,which led to confrontation between Western countries and Russia.Such a crisis also triggered the extensive involvement of nonstate actors,such as international capital giants,small and micro technology enterprises,emerging international platforms,and multinational corporations.Nonstate actors play an important role in international politics.Benefiting from the development of globalization and the accelerated evolution of the digital age,nonstate actors have exerted a significant influence on the international pattern by intervening in the competition between countries,participating in the process of global governance,and influencing the thoughts of science and technology.These actors have become an important variable affecting the world.The rising role of nonstate actors has many implications for China to expand its strength and safeguard national interests and security. 展开更多

This article aims to explore the coalition of external actors and the strategies it deployed to influence the emergence of the National Nutrition Policy (NNP) in Lao People’s Democratic Republic (Lao PDR). The Advocacy Coalition Framework and the conceptual model of Effective Advocacy Strategies for Influencing Government Nutrition Policy were used to frame the data collection and their analysis. Sources of information were semi-structured interviews conducted with government and external actors, as well as all available documents on nutrition policy in Laos. The commitment of the government to achieve the Millennium Development Goals (MDGs) and to leave the Least Developed Country status created a favorable condition to support the emergence of the NNP in Laos. This context was a driving force for the building of an effective and convincing coalition of United Nations agencies able to accompany the government in redefining health priorities. Various strategies were used by the coalition to this end, including generating, disseminating, and using scientific evidence, assisting the government with a budget and technical expertise, providing decision-makers with opportunities to learn from other countries, and building relationships with the key actor. External actors can be a major force to support the emergence of a public policy in Laos, but this requires a window of opportunity like what the MDGs have been able to bring. 展开更多

For the selection of study sites, the criterion used was the proximity of households to the area where the bamboo resource is found. Using the simple random sampling method, 53 households were surveyed across the Menoua division. Key informant and expert interviews were also conducted with mayors, traditional chiefs, heads of forestry posts, heads of research institutions/structures and craftsmen involved in the bamboo sector. Using SPHINX software version 5, a survey form was designed. The data collected was coded and analysed using EXCEL 2010 and SPSS. Map data was analysed using ARCGIS version 2.18. Results indicated that there were two main groups of actors: direct actors (collectors, <span>collectors/transporters, producers/collectors, producers/collectors/transporters,</span> collectors/traders) and indirect actors (Municipal Councils, Decentralized Services of the Ministry of Forestry and Wildlife</span></span></span><span><span><span style="font-family:"">—<span>MINFOF, Development partners like INBAR, Research Institutions like the Institute of Agricultural Research for Development</span>—<span>IRAD, and academic institutions like the University of Dschang). The direct actors are directly linked to the bamboo value chain while the indirect actors are those whose decisions influence the sector (e.g. MINFOF) or those who provide financial and technical support (Municipal Councils, INBAR;IRAD, the University of Dschang). The main strategies proposed by the local population for the development of the bamboo sector were regular sensitization campaigns on the benefits of bamboo (92%) and the provision of technical, material and financial support to bamboo producers (41%). Key informants/experts proposed the following in order to ensure the development of the bamboo sector in the Menoua division: raising awareness about bamboo, its different varieties and benefits;creating bamboo plantations (with varieties adapted to the agro-ecological zone i.e. the western highlands) in order to reduce the pressure on other resources;setting up support mechanisms for producers and other actors in the bamboo value chain;allocating land/agricultural areas for bamboo plantations as there is land scarcity in the Menoua division. Based on the strategic framework developed from this study, in order to ensure an adequate and effective development of the bamboo sector in the Menoua division, there should be among others: multiplication of awareness-raising and training programmes for farmers on bamboo production techniques;more support for smallholder farmers by providing them bamboo plants in quality and quantity;production of bamboo stems in quality and quantity;more awareness campaigns for young craftsmen on the advantages of the bamboo craft sector;more training campaigns for craftsmen on modern bamboo processing techniques;and the establishment of a well-developed and sustainable bamboo-based craft sector. 展开更多

Decentralize in forest management policies towards more people-oriented approaches has become major policy trends in many of the world’s developing countries during the last decade. However, the power of important actors to misuse the participatory forestry (PF) approach for their self-interests has been stated as a main problem to success. So, this study attempted to identify the most powerful actors and the extent at which they influence the outcomes of PF, and also to measure the impact of PF on livelihood assets of participants. The empirical data were collected from the well-established PF programs at Madhupur Sal forests area of Bangladesh. The results showed that the forest department (FD) proved itself as the most powerful and influential actor in every element of power analysis in PF. Regarding to livelihood analysis, the results revealed that the overall value of participants’ livelihood assets was 0.85 and it was significantly differed from the non-participants value of 0.66. However, the development of human, physical and financial assets was not indicating a decent improvement like as natural and social assets of participants. So, it is necessary to pay more attention to boost up participants’ human and financial assets through intensive training and adopting proper tree-crop production techniques, and also ensuring alternative livelihoods approaches to the local people. In addition, the local government will need to pay more emphasis on constructing village roads and infrastructure so as to enhance physical assets of the local people. Finally, the study would recommend promoting PF with apposite government facilities and also empowering local participants in order to balance the power among different actors, and this will facilitate the participants in governing all of their development activities efficiently. 展开更多

The Arab world has witnessed two interrelated phenomena after the Arab Spring.The first is the aggravation of the crisis of the nationstate,where many states experienced failure and disintegration,such as Libya,Syria and Yemen,while many other states continued to suffer from weakness.The second is the rise of violent non-state actors(VNSAS)such as terrorist jihadi organisations,warlords,organised crime syndicates and armed militias affiliated with political parties,tribal,ethnic and sectarian groups.The second phenomenon is a natural outcome of the first one.When the state fails,it becomes unable to monopolise the use of force,impose its control over its territory and secure it borders.These conditions create a security and political vacuum and ungoverned spaces,which are considered a suitable environment for the expansion of VNSAs.Currently,in many Arab states,the role of VNSAs makes state-building and peacemaking efforts more difficult and complicated.This article aims to analyse the causes of the crisis of nation-state building in the Arab world,which explains the failure and collapse of many Arab states once the authoritarian regimes that have governed them for decades collapsed.Also,it discusses the types of VNSAs and the reasons behind the expansion of these actors and the escalation of their roles in many Arab countries,particularly in the post-Arab Spring era.Additionally,the future of VNSAS will be examined. 展开更多

This article investigates the dynamics of rivalry and state sponsorship of non-state actors by explaining the Saudi-Iranian rivalry through the lens of securitization theory.The study elucidates that despite the enduring nature of their rivalry,both Iran and Saudi Arabia have exhibited a degree of restraint in escalating their conflicting dyadic relationship.It further notes that this behavior has forced them to securitize various issues in the region,framing them as potential threats to national and regime security,that has allowed them to build alliance and provide critical support to nonstate actors across the region.By so doing,Tehran and Riyadh seek to expand their influence and hunt their strategic and tactical objectives within the Middle East.This policy is primarily driven by geopolitical concerns rather than ideological or ethnic entitlements. 展开更多

This paper endeavours to elucidate the intricacies of Palestinian Paradiplomacy,focusing in the political impetus pioneered by its principle actors,namely the Palestine Liberation Organisation(PLO)and subsequently,the establishment of the Palestinian National Authority(PNA).Additionally,attention will be directed towards the creation of the Palestinian Ministry of Foreign Affairs(PMOFA)and its subsidiary,the Palestinian International Cooperation Agency(PICA),albeit briefly discussed.Drawing inspiration from Alexander S.Kuznetsov’s seminal work“Theory and Practice of Paradiplomacy:Subnational Governments in International Affairs”(2015),this paper tries to scrutinize the trajectory of Palestinian paradiplomacy and its evolutionary course over time.When it comes to activity and growth,Palestinian paradiplomacy has a unique profile.The way in which topics pertaining to nations are not yet recognized has a great deal of bearing on current discussions and academic research about urgent political concerns like the right to self-determination and human rights.The analysis of de facto states via the prism of paradiplomacy naturally arises from the dominant state recognition procedures in international politics. 展开更多

This paper examines how cybersecurity is developing and how it relates to more conventional information security. Although information security and cyber security are sometimes used synonymously, this study contends that they are not the same. The concept of cyber security is explored, which goes beyond protecting information resources to include a wider variety of assets, including people [1]. Protecting information assets is the main goal of traditional information security, with consideration to the human element and how people fit into the security process. On the other hand, cyber security adds a new level of complexity, as people might unintentionally contribute to or become targets of cyberattacks. This aspect presents moral questions since it is becoming more widely accepted that society has a duty to protect weaker members of society, including children [1]. The study emphasizes how important cyber security is on a larger scale, with many countries creating plans and laws to counteract cyberattacks. Nevertheless, a lot of these sources frequently neglect to define the differences or the relationship between information security and cyber security [1]. The paper focus on differentiating between cybersecurity and information security on a larger scale. The study also highlights other areas of cybersecurity which includes defending people, social norms, and vital infrastructure from threats that arise from online in addition to information and technology protection. It contends that ethical issues and the human factor are becoming more and more important in protecting assets in the digital age, and that cyber security is a paradigm shift in this regard [1]. 展开更多

In recent years,Francophone schools in Alberta,a province in western Canada,have seen significant ethnocultural diversification of their school population,thus reflecting recent migratory changes in Canada.The population of a Francophone school board located in an agglomeration of Alberta reflects these new migratory trends.A partial ethnodemographic portrait carried out in 2003 in six of its schools indicates that 50%of the pupils come from an immigrant background and come from 23 different countries;mostly from sub-Saharan African countries.This demographic reality,confirmed more than a decade later,represents a major structural change for Francophone schools.In Alberta,as in other Canadian provinces,inclusion is at the heart of discourse and educational practices.With a transformative aim,it intends to promote ethnocultural diversity in the classroom and equal opportunities through school equity practices.This article focuses on the settlement workers in schools responsible for bridging family,community,and school cultures.The analysis of the interviews of the four workers sheds light on and questions both the institutional practices and the personal strategies put in place to face the challenges encountered in this tripartite collaboration. 展开更多

It is an important way to realize rural revitalization and sustainable development to guide rural settlement transition(RST)in an appropriate way.This paper uses actor network theory(ANT)to construct a theoretical framework for the study of RST.Taking two typical villages with different transition paths in rural areas of North China Plain as examples,this paper reveals the mechanism of RST and makes a comparative analysis.The results show that:1)after identifying problems and obligatory passage point,key actors recruit heterogeneous actors into the actor network by entrusting them with common interests,and realize RST under the system operation.2)Rural settlements under different transition paths have similarities in the problems to be solved,collective actions and policy factors,but there are differences in the transition process,mechanism and effect.The actor network and mechanism of RST through the path of new rural community construction are more complex and the transition effect is more thorough.In contrast,the degree of RST of retention development path is limited if there is no resource and location advantage.3)Based on the applicable conditions of different paths,this paper designs a logical framework of‘Situation-Structure-Behavior-Result’to scientifically guide the identification of RST paths under the background of rural revitalization. 展开更多
