Newspapers published by Roman Catholic dioceses represent a large and unexplored part of the religious publishing industry. This study attempts to shed light on the challenges these publications face by examining the readership of a diocesan newspaper in a large Catholic diocese in the Mid-Atlantic region of the United States. Based on a comprehensive survey of 24,278 Roman Catholic households from 27 parishes throughout the diocese, this study finds a large gap in readership and engagement between older and younger readers, raising important strategic and pastoral questions for the newspaper in the years to come. 相似文献

We consider the task of generating discrete-time realisations of a nonlinear multivariate diffusion process satisfying an Itô stochastic differential equation conditional on an observation taken at a fixed future time-point. Such realisations are typically termed diffusion bridges. Since, in general, no closed form expression exists for the transition densities of the process of interest, a widely adopted solution works with the Euler–Maruyama approximation, by replacing the intractable transition densities with Gaussian approximations. However, the density of the conditioned discrete-time process remains intractable, necessitating the use of computationally intensive methods such as Markov chain Monte Carlo. Designing an efficient proposal mechanism which can be applied to a noisy and partially observed system that exhibits nonlinear dynamics is a challenging problem, and is the focus of this paper. By partitioning the process into two parts, one that accounts for nonlinear dynamics in a deterministic way, and another as a residual stochastic process, we develop a class of novel constructs that bridge the residual process via a linear approximation. In addition, we adapt a recently proposed construct to a partial and noisy observation regime. We compare the performance of each new construct with a number of existing approaches, using three applications. 相似文献

Objective: To discuss the potential of a café on the premises of an aged-care facility as a vehicle for culture change. Method: Secondary analysis of primary qualitative data that explored the value of a café in an aged-care facility, compared with culture-change principles established from a literature review. Results: Secondary analysis established congruence between culture-change principles and the themes established in the primary qualitative data. A café, in one aged-care facility, has facilitated the following dimensions of culture change for residents: individualized care, facilitation of meaningful relationships, opportunities for participation in life roles, and creation of a sense of belonging. Conclusion: Culture change can be achieved through environmental innovations, such as a café, where food and dining maximize social opportunities and create a homelike environment that facilitates continuation of residents' identity. 相似文献

Over the last fifteen years companies tended to formalise their innovation management activities and to establish formal jobs like the innovation officer, the network manager or the innovation manager. Knowledge of the informal role profiles of these formal roles is still rare. HR and R&D Managers do not know which informal role profile might suit them best, thus having difficulties to assign the best candidates for jobs in innovation management. Researchers cannot help to resolve the problem. Our research answers the question what innovation managers really do, by analysing their tasks, skills and traits, theoretically based on informal role theories. Furthermore, we will analyse how these characteristics change with company size. To provide answers to our research questions we choose a multiple-case study approach. We found, among others, that innovation managers fulfil the role of the relationship and process promotor or a combination of both with the champion, but we also found, that the innovation manager’s roles profile becomes fuzzier with shrinking company size. Our results have practical implications for top management and also HR and R&D managers, enabling them to better select and steer employees in innovation management. Researchers will be able to build on our results because we offer a comprehensive understanding of the informal role profiles of innovation managers based on informal role theories. 相似文献
