随着习近平总书记提出总体国家安全观,关于国家安全的研究不断丰富和扩大。文化安全作为国家安全的重要保障,意识形态领域的安全又是文化安全的根本要求,高校学生的思维易受外界影响,需要重点教育引导。高校国防教育活动作为意识形态安全教育的主要形式,对于加强国家文化安全有着重要作用。为了切实加强社会主义意识形态安全教育,为国家发展做好文化安全保障,高校国防教育应该从国家安全的高度指导教学,改革教育的内容和方式。 相似文献

The term national language capacity refers to the sum total of a nation’s ability to grasp linguistic resources, provide language services, deal with linguistic issues, develop the language, and related tasks. Key capacities include the possession of linguistic resources, utilization of language and language services, development and use of linguistic resources, the language of the members of the nation, reserves of linguistic talent, language management, development of language enterprises and linguistic influence. The development of informatization has made national language capacity an important part of national strength. It is hard power as well as soft power, playing a very important role in social progress and cultural inheritance, in promoting economic development and technological innovation, and in protecting a country’s national security and international development. 相似文献

Focusing on the model selection problems in the family of Poisson mixture models (including the Poisson mixture regression model with random effects and zero‐inflated Poisson regression model with random effects), the current paper derives two conditional Akaike information criteria. The criteria are the unbiased estimators of the conditional Akaike information based on the conditional log‐likelihood and the conditional Akaike information based on the joint log‐likelihood, respectively. The derivation is free from the specific parametric assumptions about the conditional mean of the true data‐generating model and applies to different types of estimation methods. Additionally, the derivation is not based on the asymptotic argument. Simulations show that the proposed criteria have promising estimation accuracy. In addition, it is found that the criterion based on the conditional log‐likelihood demonstrates good model selection performance under different scenarios. Two sets of real data are used to illustrate the proposed method. 相似文献

Can Carbon Nanomaterials Improve CZTS Photovoltaic Devices? Evaluation of Performance and Impacts Using Integrated Life‐Cycle Assessment and Decision Analysis 下载免费PDF全文
In emergent photovoltaics, nanoscale materials hold promise for optimizing device characteristics; however, the related impacts remain uncertain, resulting in challenges to decisions on strategic investment in technology innovation. We integrate multi‐criteria decision analysis (MCDA) and life‐cycle assessment (LCA) results (LCA‐MCDA) as a method of incorporating values of a hypothetical federal acquisition manager into the assessment of risks and benefits of emerging photovoltaic materials. Specifically, we compare adoption of copper zinc tin sulfide (CZTS) devices with molybdenum back contacts to alternative devices employing graphite or graphene instead of molybdenum. LCA impact results are interpreted alongside benefits of substitution including cost reductions and performance improvements through application of multi‐attribute utility theory. To assess the role of uncertainty we apply Monte Carlo simulation and sensitivity analysis. We find that graphene or graphite back contacts outperform molybdenum under most scenarios and assumptions. The use of decision analysis clarifies potential advantages of adopting graphite as a back contact while emphasizing the importance of mitigating conventional impacts of graphene production processes if graphene is used in emerging CZTS devices. Our research further demonstrates that a combination of LCA and MCDA increases the usability of LCA in assessing product sustainability. In particular, this approach identifies the most influential assumptions and data gaps in the analysis and the areas in which either engineering controls or further data collection may be necessary. 相似文献

Efforts to explain why some people incorporate ethical concerns into everyday shopping for food and household goods, while many do not, have so far left significant variation in “ethical consumption” unexplained. Seeking to move beyond explanations that rely mainly on differences in consumers' social class, gender, and political engagement, I draw on concepts associated with “practice theory” to argue that ethical consumption is closely tied to people's willingness and ability to spend time, while shopping, on distinct activities associated with breaking old routines and establishing new ones. The central insight of practice theory is that most consumption is the product of unconscious routine. And it is precisely because consciously departing from routine is, according to my study, a fundamentally time‐consuming process, that lack of time emerges as a crucial obstacle to translating abstract ethical concerns into concrete action as a consumer. 相似文献

Despite strong political commitment, actual gains in improving accountability in development co‐operation have been limited. Main reasons for this include the low level of transparency and high number of actors, as well as the limitations of the self‐reported and input‐oriented OECD reporting system. Efforts through the International Aid Transparency Initiative (IATI) and related transparency initiatives are ill‐equipped to change this given their decision to adhere to the same system. This article uses the specific area of support to capacity development to illustrate this. While further disaggregation of reporting on technical co‐operation could respond to a transparency gap, overcoming the accountability gap requires moving beyond promoting ‘supply‐side’ reform and re‐engaging in efforts to promote collective action. 相似文献

The aim of this study is to determine the risk factors and protective factors of being a victim of couple violence, considering cultural conventions, coping, social support, external attribution and violence in childhood. A non-probabilistic sample of 223 women and 177 men was used. The risk factors in the sample as a whole were being male, the coping strategy of accommodation, violence in childhood and external attribution, while the protective factors were partner support and an active coping style. The study concludes with suggestions for interventions and research. 相似文献

The implications of the 2011 Scottish election and the proposed referendum on Scottish independence for the future of social policy across the devolved UK are profound but far from certain. It is crucial to understand not only the historical nature of this conjuncture but to develop an adequate conceptual understanding of the place of social policy in the dialectic between state and nation in Scotland. To this end, we critically examine theories that depict Scotland as an essentially ‘stateless nation’ in the light of recent developments. In so doing, we examine the implications for social policy of the changing character of statehood in Scotland, the nature of civil nationalism, and the problem of legitimacy in Scotland for the UK as a multinational state. As the architecture of statehood is re‐negotiated, strong centrifugal pressures are being created for a more distinct divergence of social policy in Scotland from the rest of the UK regardless of the outcome of the independence referendum. Policy‐making is ensnared in a series of tensions, not just between Westminster and Holyrood but also, more broadly, tensions between competing principles of social justice and territorial justice, and competing demands between welfare nationalism and competitive nationalism. 相似文献
