促进人民群众对习近平新时代中国特色社会主义思想的认同,是当前重大理论和实践问题.而构建动力机制、健全引导机制、完善保障机制有利于强化对习近平新时代中国特色社会主义思想的认同.构建动力机制,需要以实现中华民族伟大复兴的中国梦激发认同的情感动力,以让人民群众有更多获得感、幸福感、安全感增强认同的利益动力,以理论的科学性增加认同的思想动力;健全引导机制,需要以理论研究为支撑,完善教育机制;以正确舆论为导向,强化宣传机制;以阵地建设为平台,健全导向机制;完善保障机制,需要壮大经济基础,突出利益认同;健全民主政治,增强政治认同;坚持文化自信,强化价值认同;夯实民生基础,巩固社会认同;推进绿色发展,提升生态认同.  相似文献

For the hierarchical Poisson and gamma model, we calculate the Bayes posterior estimator of the parameter of the Poisson distribution under Stein's loss function which penalizes gross overestimation and gross underestimation equally and the corresponding Posterior Expected Stein's Loss (PESL). We also obtain the Bayes posterior estimator of the parameter under the squared error loss and the corresponding PESL. Moreover, we obtain the empirical Bayes estimators of the parameter of the Poisson distribution with a conjugate gamma prior by two methods. In numerical simulations, we have illustrated: The two inequalities of the Bayes posterior estimators and the PESLs; the moment estimators and the Maximum Likelihood Estimators (MLEs) are consistent estimators of the hyperparameters; the goodness-of-fit of the model to the simulated data. The numerical results indicate that the MLEs are better than the moment estimators when estimating the hyperparameters. Finally, we exploit the attendance data on 314 high school juniors from two urban high schools to illustrate our theoretical studies.  相似文献

ABSTRACT

This paper explores the difference in the online economic activities of people with and without disabilities in Korea. We conducted a multiple regression analysis to investigate the impact of socioeconomic characteristics, internet access, and internet skills on online economic activities. Our sample, based on a 2016 dataset that included 1554 people with disabilities and 6004 people without disabilities, was developed using quota sampling based on gender, age, and residence. We determined that individuals with disabilities were more likely to engage in online economic activities if they had higher levels of education, lived in urban areas, were employed, or had greater internet skills. Individuals without disabilities were more likely to engage in online economic activities if they were women, had higher levels of education, were employed, lived in a two-generation or more household, or had greater internet skills. For both people with and without disabilities, the level of education, employment status, and internet skills positively contribute to online economic activites. We also determined that education level, participation in economic activity, living in a two-generation or more household, and internet skills had a statistically significant influence on online economic activity for people both with and without disabilities. These results highlight the importance of education and internet training for people with disabilities, as well as social support systems that help them learn to use the internet in diverse ways through both formal and informal networks. The study also underscores the importance of information and communications technology that adequately addresses people’s needs.  相似文献

In this article, we consider an ergodic Ornstein–Uhlenbeck process with jumps driven by a Brownian motion and a compensated Poisson process, whose drift and diffusion coefficients as well as its jump intensity depend on unknown parameters. Considering the process discretely observed at high frequency, we derive the local asymptotic normality property. To obtain this result, Malliavin calculus and Girsanov’s theorem are applied to write the log-likelihood ratio in terms of sums of conditional expectations, for which a central limit theorem for triangular arrays can be applied.  相似文献

The objective of this study was to measure the relationships between online sexual compulsivity, three dimensions of dissociation (absorption, depersonalization, and amnesia), and past child abuse among men who have sex with men (MSM). A total of 517 MSM, recruited from Internet chat rooms, completed the survey. Results indicated that past child abuse was significantly related to dissociation but not online sexual compulsivity. It was also found that the amount of time MSM spent online in a one-week period, in general and specifically engaged in sexual activity, was significantly related to online sexual compulsivity and three dimensions of dissociation. Online sexual compulsivity was a significant predictor of absorption, depersonalization, and amnesia. Implications for clinicians and future research are presented.  相似文献

This study investigates how large companies respond to public policy measures to ensure the inclusion of persons with disabilities in mainstream employment based on a case study of four companies in Norway and Sweden. The qualitative interviews, which were conducted with company managers, government representatives in Norway, and non-governmental organisations in Sweden, revealed three overarching themes: (1) ‘legitimacy’, (2) ‘financial interests’ and (3) ‘non-financial support’. The results indicate a more proactive response from the Swedish companies, especially regarding persons with intellectual and learning difficulties. The Norwegian companies reveal a high commitment to their own employees. These findings cannot be explained solely using neo-institutional theory, which holds that organisations demonstrate ‘conformity with powerful institutional myths to strengthen support and secure survival'. The results indicate that inclusive targeted corporate policies and programmes, advisory support, and the agency and value choices of the management might matter more.  相似文献

We begin by definition of semi-Markov flow and discussion of its properties. Asymptotic behavior of multi-server and single-server queueing systems is studied under assumption of time-compression or service time growth. The results obtained are used for calculation of large systems reliability. Statistical estimates of parameters involved are also provided.  相似文献

Unemployment among persons with disabilities is high. The situation is worse for women with disabilities as they experience multiple disadvantages on account of gender and disability. The condition for women with disabilities in Ghana could be more complicated, given the intersection of disability, gender, poverty, cultural beliefs and practices. As employment provides not only income for women with disabilities but opportunities for social participation and increases psychological well-being as well as self-esteem, it is imperative to remove barriers that hinder their employment. The current study examines issues associted with the unemployment of women with physical disabilities in Tamale, Ghana, and makes recommendations to policy-makers and practitioners in order to improve the condition of persons with disabilities in general, and particularly women with disabilities.  相似文献
