十三万户的建立和八思巴受封“帝师”是元代西藏历史上的两个重要问题,但十三万户建立的时间和名称以及八思巴受封帝师的时间和封号的内容,在各种汉藏文史料中记载不同,以致在教学中出现混乱现象。本文拟通过以汉藏文史料对比的形式,对这两个历史问题进行考证,以期得到更符合历史史实的认识。 相似文献

Although various studies have emphasized linkages between firm competencies, networks and sustainability at organizational level, the links between top management tangible competencies (TMTCs) (e.g. contemporary relevant quantitative‐focused education such as big data analytics and data‐driven applications linked with the internet of things, relevant experience and analytical business applications), relationship‐based business networks (RBNs) and environmental sustainability have not been well established at micro‐level, and there is a literature gap in terms of investigating these relationships. This study examines these links based on the unique data collected from 175 top management representatives (chief executive officers and managing directors) working in food import and export firms headquartered in the UK and New Zealand. Our results from structural equation modelling indicate that TMTCs are the key determinants for building RBNs, mediating the correlation between TMTCs and environmental sustainability. Directly, the competencies also play a vital role towards environmental practices. The findings further depict that relationship‐oriented firms perform better compared to those which focus less on such networks. Consequently, our findings provide a deeper understanding of the micro‐foundations of environmental sustainability based on TMTCs rooted in the resource‐based view and RBNs entrenched in social network theory. We discuss the theoretical and practical implications of our findings, and we provide suggestions for future research. 相似文献

This article presents an assessment of individual uncertainty about longevity. A survey performed on 3,331 French people enables us to record several survival probabilities per individual. On this basis, we compute subjective life expectancies (SLE) and subjective uncertainty regarding longevity (SUL), the standard deviation of each individual’s subjective distribution of her or his own longevity. It is large and equal to more than 10 years for men and women. Its magnitude is comparable to the variability of longevity observed in life tables for individuals under 60, but it is smaller for those older than 60, which suggests use of private information by older respondents. Our econometric analysis confirms that individuals use private information—mainly their parents’ survival and longevity—to adjust their level of uncertainty. Finally, we find that SUL has a sizable impact, in addition to SLE, on risky behaviors: more uncertainty on longevity significantly decreases the probability of unhealthy lifestyles. Given that individual uncertainty about longevity affects prevention behavior, retirement decisions, and demand for long-term care insurance, these results have important implications for public policy concerning health care and retirement. 相似文献

Mutual help has been often found to be beneficial for people’s well-being in clinical settings. Research in the general population,
however, is relatively limited, partly due to the lack of applicable measurement tools. The present study attempted to develop
two scales to measure mutual help willingness and criteria and test their psychometric properties among a community sample
of Hong Kong people (n = 951). Confirmatory factor analyses suggested that the hypothetical models fitted the data very well. Results also indicated
that though the willingness to seek help and to give help was significantly correlated, Hong Kong people were generally more
willing to give help than to seek help. Age had a negative effect on help-seeking willingness, which can not be explained
by education level. A set of criteria were applied similarly when people decided on help-giving and help-seeking. Agreement
with the criteria was negatively correlated with age but the associations became negligible when education level was controlled.
Research and practical implications of the findings are discussed. 相似文献

Analyses of Russian society often refer to the emergence of a new middle class in Russia, but attempts to establish its existence, size, characteristics, and behaviors are contradictory and inconclusive. In surveying this debate, Samson and Krasil'nikova argue that this is no longer a useful concept, and that a population's ability to adapt to global economic forces should be the basis for distinguishing strata. 相似文献

The researchers investigated employers' experiences with individuals with a mental illness and in their workplaces. Seventy-two business owners or human resource managers were interviewed. Most knew the prospective employee's health background prior to deciding to employ them. The majority of the reported experiences with employed individuals were very positive. Key strategies the employers or managers reported using to support employees were: to create trustworthy relationships, to work through issues and to seek external support. 相似文献

Parametric incomplete data models defined by ordinary differential equations (ODEs) are widely used in biostatistics to describe biological processes accurately. Their parameters are estimated on approximate models, whose regression functions are evaluated by a numerical integration method. Accurate and efficient estimations of these parameters are critical issues. This paper proposes parameter estimation methods involving either a stochastic approximation EM algorithm (SAEM) in the maximum likelihood estimation, or a Gibbs sampler in the Bayesian approach. Both algorithms involve the simulation of non-observed data with conditional distributions using Hastings–Metropolis (H–M) algorithms. A modified H–M algorithm, including an original local linearization scheme to solve the ODEs, is proposed to reduce the computational time significantly. The convergence on the approximate model of all these algorithms is proved. The errors induced by the numerical solving method on the conditional distribution, the likelihood and the posterior distribution are bounded. The Bayesian and maximum likelihood estimation methods are illustrated on a simulated pharmacokinetic nonlinear mixed-effects model defined by an ODE. Simulation results illustrate the ability of these algorithms to provide accurate estimates. 相似文献

Influenced by the consumerist sentiment in New Public Management,the last decades have witnessed a revival of the call for accountabilityto service users in the public service sector. As an act ofaccountability, social care and health care professionals areincreasingly obliged to involve their service users in the serviceplanning and monitoring process. Despite the popularity of thisaccountability and user involvement rhetoric, critics have,however, been skeptical of the prevailing user involvement initiativesas an effective measure of accountability to service users (Barnes and Wistow, 1994a,1994b; Bowl, 1996; Peck et al., 2002; Rea, 2004). Based on astudy of user involvement in the welfare sector of Hong Kong,this paper argues that the discourse of accountability to theservice users can be a source of unrest for welfare professionals,in the manifestation of accountability as a power relationship.Their ensuing response is to accommodate the ensuing challengearising from the demand for accountability to service usersby manoeuvring the accountability discourse. It is the contentionof this paper that the institutional inclusion of welfare serviceusers into a discursive space is a necessary but not sufficientcondition for the realization of a mandate of accountabilityto welfare service users. 相似文献

We examined the reasoning of children and adolescents in the island of Macao regarding the bases of legitimate authority across social contexts. We asked 101 children in 3rd, 5th, and 7th grades to evaluate the authority of persons issuing commands to children in two events. In one, persons with varying combinations of authority attributes issue a command that resolves a turn‐taking dispute between children in school. In another, persons with varying social positions issue a command to children to stop playing ball across three contexts: school, home, and a public park. Results show that, although young Macanese reason in many ways similar to American children, social position may be a less important legitimizing authority attribute for them than for American children. 相似文献
