Locus of Control and Its Influence on Hotel Managers' Job Satisfaction

Abstract

Studies have demonstrated that internal/external locus of control impacts job satisfaction. Additionally, research indicates that locus of control relates to many other work-related perceptions. However, few studies exist that investigate the relationship between locus of control and job satisfaction for hotel managers. This study investigates hotel managers' job satisfaction (n = 68), internal/external locus tendencies, and the relationship between the two constructs. The results indicate that variables other than the locus personality construct may relate to hotel managers' perception of job satisfaction. Additionally, the results stimulate the ongoing person versus situation debate in job satisfaction research.     

Matching visitation-motives and restaurant attributes in casual dining restaurants

This study empirically examines the relationship between the visitation motives and attributes evaluation in the casual dining restaurant context. Based on the focus group discussions, the visitation motives and the restaurant attributes that are considered relevant by the patrons in evaluation of restaurant experience were identified. Data on restaurant visitation motives and attributes importance was collected from 316 patrons of casual dining restaurants in India. A nonlinear canonical correlation was performed to examine the relationship between visitation motives and attributes importance. The results reveal that the attribute importance varied across the visitation motives. Managerial implications, limitations and future research directions are also suggested.     

基于聚类和最优尺度分析的户外拓展运动的安全风险研究

户外拓展运动是一种需要进行风险管理的活动形式。文章基于户外拓展学员的认知,对拓展活动的安全风险引致因素和安全风险表现类型进行问卷调查,并对风险引致因素类型和风险表现类型进行聚类分析。研究引入最优尺度分析中的非线性典型相关分析方法,对个体因素与拓展安全风险间的相关关系进行统计识别。研究发现,拓展安全风险引致因素和拓展安全风险表现类型均具有聚类特征,并与拓展参与者的个性特征变量具有非线性相关关系。     

创新型城市评价指标体系的实证研究——基于相关性分析

本文提出了一套较全面的创新型城市评价指标体系,并以国内较有代表性的13座城市为样本,运用相关性分析方法对指标体系进行定量分析,据此筛选出其中最精炼的评价指标。目前指标体系设计通常采用定性分析方法,这种方法受主观影响较大,本文通过定性分析与定量分析相结合的方法设计指标体系,在一定程度上弥补了这个缺陷,体现了指标体系设计的科学性,对丰富和完善创新型城市综合评价指标体系具有一定的理论借鉴意义。     

医学专科学生自我和谐与应对方式的相关分析

为了研究医学专科学生的自我和谐状况与应对方式之间的关系,并找出影响学生和谐的主要因素,给心理健康教育、心理咨询和治疗提供一些参考参考,本文通过采用简易应对方式问卷和自我和谐量表,对557名医学专科学生进行测试。并对测试结果做了技术统计,通过对数据的分析研究发现积极应对方式对自我的灵活性有着正相关的影响,而对自我与经验的不和谐、自我的刻板性、自我和谐是负相关的影响。基于这种分析结果提出了一些改善医学专科学生自我和谐的一些建议,教育部门和教育者要注重医学专科学生的积极应对方式的培养。     

中国入境旅游市场灰色关联度分析及启示

选取代表入境旅游市场发展规模的入境旅游人次作为研究对象,通过灰色关联度分析,探讨和揭示中国入境外国旅游市场发展变化态势．结果显示：中国入境外国旅游市场性别关联度为男性〉女性,年龄关联度为15-24岁市场〉25-44岁市场〉45-64岁市场〉65岁以上市场〉14岁以下市场I旅游目的关联度为商务会议〉员工服务〉其他〉观光休闲〉探亲访友。因此,可以用男性市场、15-24岁市场和商务会议市场预测入境旅游发展态势,以此做出入境旅游营销费用和营销努力大小的决策．然后,在营销费用和营销努力的匹配方面．应向男性市场、25-44岁与45-64岁市场、商务会议与观光休闲市场倾斜．     

Temporal aggregation and spatio-temporal traffic modeling

Traffic forecasting is crucial for policy making in the transport sector. Recently, Selby and Kockelman (2013) have proposed spatial interpolation techniques as suitable tools to forecast traffic at different locations. In this paper, we argue that an eventual source of uncertainty over those forecasts derives from temporal aggregation. However, we prove that the spatio-temporal correlation function is robust to temporal aggregations schemes when the covariance of traffic in different locations is separable in space and time. We prove empirically this result by conducting an extensive simulation study on the spatial structure of the Milan road network.
