Consider N independent stochastic processes \((X_i(t), t\in [0,T])\), \(i=1,\ldots , N\), defined by a stochastic differential equation with random effects where the drift term depends linearly on a random vector \(\Phi _i\) and the diffusion coefficient depends on another linear random effect \(\Psi _i\). For these effects, we consider a joint parametric distribution. We propose and study two approximate likelihoods for estimating the parameters of this joint distribution based on discrete observations of the processes on a fixed time interval. Consistent and \(\sqrt{N}\)-asymptotically Gaussian estimators are obtained when both the number of individuals and the number of observations per individual tend to infinity. The estimation methods are investigated on simulated data and show good performances. 相似文献

Nonprofit arts and cultural organizations use marketing to sustain viability. This study uses data from the Cultural Data Project to examine the effects of marketing on revenue in arts and cultural organizations. The current analysis demonstrates that total marketing expense is positively related to total revenue. Marketing expense used for fund‐raising positively influences donation income, as intended, whereas commercial income is not affected. Alternatively, marketing expense for programs positively influences both commercial income, as intended, and donation income. The novel finding from this study is that marketing expense mainly targeting non‐donor ticket buyers not only increases commercial income but also augments donation income in arts and cultural organizations. 相似文献

This study aims to develop a measurement scale for organizational career management (OCM) in China's hotel industry. The scale development procedure includes four steps: developing initial items, implementing purifying measures, data collection, and assessing the reliability and validity of the proposed measurement scale. Both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) are used to test the reliability and validity of the measurement scale thus developed. The development process results in a reliable and valid scale for hotel career management incorporating three dimensions: (1) career appraisal and advice, (2) a career development program, and (3) career training. Given the scarcity of research on career management in China, the measurement scale developed in this study will serve as a foundation for future research. The findings of this study may help to stimulate further empirical research on the relationship between hotel career management and employees’ career commitment and career satisfaction. 相似文献

This study aims to explore the determinants and outcome of career competencies. Based on the notion that organizations and individuals have respective obligations in the career management of employees’, this study developed perceived “organizational career management’ (OCM) and “career commitment” as determinants and career satisfaction as an outcome of career competencies. Data were collected in the state-owned hotels in China, and structural equation modeling was used to test the proposed relationships. The findings indicate that both perceived OCM and career commitments have positive, direct effects on career competencies. The findings of this study may benefit both hotels and hotel employees by providing valuable implications. 相似文献

The purpose of this study is to explore the relationships between perceived hotel career management, career competency, and career satisfaction. It also aims to examine the mediating processes through which hotel career management contribute to employees’ career satisfaction. Results from structural equation modeling (SEM) show that career competency mediates the effects of three dimensions of hotel career management (career appraisal, career development, and career training) on career satisfaction. The article concludes with implications for theory development and management practice. 相似文献

Much of the literature on authenticity is Western-centric, while little work addresses the concept in the Asian environment. The literature relating to authenticity from Asian tourists’ point of view is even underdeveloped. This study therefore aims to fill the knowledge gap by investigating Chinese tourists’ perspective of authenticity. It also examines tourists’ perceived authenticity as a multi-dimensional construct in a consumer-based model, the relationship with heritage motivation and tourist satisfaction. Findings indicate that Chinese tourists’ perceptions of authenticity are closely related to objective and constructive authenticity. The study demonstrates that heritage motivation has a significant positive influence on perceived authenticity and that perceived authenticity has a strong ability to predict tourist satisfaction. 相似文献

Human-mediated seed dispersal is recognised as an important, but under-researched, issue. To assess the potential for tourists to act as unintentional seed dispersal agents, we reviewed published and unpublished data on seed dispersal via clothing, vehicles (cars) and in/on horses and donkeys, all of which can be used by tourists. Seeds from 754 species of terrestrial plants have been collected from these vectors, 15% of which are internationally recognised environmental weeds. Seeds were collected from personal clothing and equipment (228 species), the fur of donkeys and horses (42 species), horse dung (216 species) and vehicles (505 species). Most were herbs (429 species) or graminoids (237 species) and native to Europe. Annual Poa, White Clover, Kentucky Bluegrass and Yorkshire Fog were the most frequent species. There have been eight studies specifically on tourists, which identified 12 species on clothing, 26 on vehicles and 133 from horse dung. Methods that minimise the risk of tourists as human-mediated dispersal agents may therefore be appropriate for some tourism activities/destinations: suggestions are made. Further sampling using standardised experimental techniques is required to assess the relative risk associated with specific tourist activities and locations and determine which, and how much, seed is transported. 相似文献
