This paper presents a modeling methodology capable of accounting for spatial correlation across choice alternatives in discrete choice modeling applications. Many location choice (e.g., residential location, workplace location, destination location) modeling contexts involve choice sets where alternatives are spatially correlated with one another due to unobserved factors. In the presence of such spatial correlation, traditional discrete choice modeling methods that are often based on the assumption of independence among choice alternatives are not appropriate. In this paper, a Generalized Spatially Correlated Logit (GSCL) model that allows one to represent the degree of spatial correlation as a function of a multi-dimensional vector of attributes characterizing each pair of location choice alternatives is formulated and presented. The formulation of the GSCL model allows one to accommodate alternative correlation mechanisms rather than pre-imposing restrictive correlation assumptions on the location choice alternatives. The model is applied to the analysis of residential location choice behavior using a sample of households drawn from the 2000 San Francisco Bay Area Travel Survey (BATS) data set. Model estimation results obtained from the GSCL are compared against those obtained using the standard multinomial logit (MNL) model and the spatially correlated logit (SCL) model where only correlations across neighboring (or adjacent) alternatives are accommodated. Model findings suggest that there is significant spatial correlation across alternatives that do not share a common boundary, and that the GSCL offers the ability to more accurately capture spatial location choice behavior. 相似文献

征信法规建设的滞后使得中国人民银行分支机构征信工作缺乏法律依据,一定程度上制约了征信执法效能的发挥。为提高征信执法效能,应进一步完善《征信管理条例》并使之尽早出台,加快制定企业征信方面相关办法、《个人信用信息基础数据库管理办法》实施细则和信用评级方面相关办法等。 相似文献

Freight on Transit (FOT) refers to an operational strategy where public transit vehicles and/or infrastructure are used to move freight. Examples include moving goods alongside passengers on buses, attaching cargo trailers to transit vehicles, and operating freight vehicles between trains on subway lines. This paper describes the methods and results of a three-round Delphi study engaging 34 transportation experts to explore challenges and opportunities of FOT and to conceptualize and evaluate potential FOT operations in Toronto. Traditional Delphi methods were used for the exploration of FOT challenges and opportunities, and a modified approach was formulated to integrate experts' opinions and develop new FOT concepts for Toronto. The results support previous claims that technical challenges of FOT may be easier to overcome than institutional barriers. Evaluation of potential FOT operating strategies in Toronto suggests that while the current public transit network does not have capacity to support additional movements, there may be realistic opportunities to include freight service in future projects as a means of offsetting operating costs and reducing the impacts of goods movements. 相似文献

Tourism is one of the more important sectors for the economy of Galicia (northwest of Spain). The aim of our study is to quantify determinants of Galician domestic tourism demand and their impacts. Additionally, confidence intervals for these impacts are calculated by bootstrapping data. The results show that income, Eastern vacations and the celebration of the Holy Year of the Apostle Saint James have had a relevant positive impact on tourism. There is also a significant positive connection between a meteorological phenomenon, the North Atlantic Oscillation (NAO), and tourism demand. On the other hand, the differential rates of inflation between Galicia and the rest of Spain and the 2008 economic crisis have had a negative effect. 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

Scholarly concerns in organizational citizenship behaviors (OCBs) have increased dramatically over the past two decades. Nevertheless, there are significant issues yet to be addressed and resolved, one of which relates to the influences of cultural values on such voluntary behaviors. In view of the importance of OCB in meliorating hotel service and cultivating customer loyalty, the current study seeks to investigate a possible mechanism through which Chinese values (CVs) may function on employee citizenship behaviors within the hotels in Mainland China. The research questions focus on whether CVs have a direct impact on OCB and its verified antecedents, leader–member exchange (LMX) and employee organizational commitment (OC). Eventually, the research findings have verified the conceptual model and confirmed all the postulated linkages among the constructs under study. 相似文献

“中国农村象非洲”、“共产党还要我们穷多久”,这两种声音应该成为推进新农村建设的强大动力。从传统农业发展模式转变到大农业发展模式是新农村建设成败的关键;县级领导的作用与县域经济的现状,关系到能否完成新农村建设的重大任务;应将山区作为新农村建设的主战场,把发展农村合作组织作为工作重点,要处理好农村工作中的点面关系,要把尊重自然规律摆到主导位置。 相似文献
