Applying the counseling-learning approach to a tourism-related massive open online course

ABSTRACT

This study discusses how to apply counseling-learning (CL) principles to a particular e-learning solution for teaching a tourism-related subject via a massive open online course (MOOC). Several effective caring patterns in achieving learning-related goals and being part of a community according to the CL principles are presented and discussed using the MOOC “eTourism: Communication Perspectives” as a case study. The study underlines how the MOOC platform can act as a place for contents enjoinment and active learning. Moreover, the active role of social media for increasing the engagement of learners in the proposed activities and for developing a sense of the community is identified. In particular, Facebook and Twitter can act as places for community building and informal social interactions among learners that last beyond the completion of the course, which in turn can be a valid aid for continuing the relationships among instructors/learners and learners/learners, and for reaching new ones.     

黑土典型区有机质高光谱预测模型

土壤有机质(SOM)是鉴别土壤肥力的重要指标,是土壤肥力的物质基础,其含量预测模型研究对于土壤肥力评价、土壤碳库估算、土壤资源利用与保护具有重要意义。该文以黑龙江省黑土带典型区为例,采集区域土壤样本,基于有机质含量与土壤反射率的定量关系,对光谱反射率进行一阶微分和倒对数的处理,建立偏最小二乘法模型(PLSR)、一元线性回归模型和多元线性逐步回归模型。结果表明:(1)土壤有机质敏感波段位于650-750nm。(2)通过比较建模样本与检验样本的决定系数(R2)和均方根误差(RMSE)的大小,得到反射率和倒对数处理后的数据最优模型都为PLSR模型,一阶微分处理后的最优模型为多元线性逐步回归模型。(3)PLSR模型的建模效果优于回归模型,但其预测效果却并不理想。该研究将为改进土壤理化参数、遥感反演、土地质量评价等工作方法提供理论与技术支持。     

Curriculum assessment through a capstone course: a case study in hospitality and tourism programs

The purpose of this study was to develop a systematic process that other educational institutions and programs could follow to establish a consistent and accurate evaluation method for a capstone course. Hospitality industry professionals and hospitality management faculty were interviewed through focus-group discussions, and a post-focus-group survey was conducted to determine a weighted percentage for each of the nine determined content domains. A test blueprint for a hospitality management capstone course was developed to measure programmatic student learning outcomes based on the weighted domains determined through this study. The results provide a usable instrument for hospitality and tourism management programs to enhance their current assessment methodology.

How to estimate market concentration given grouped data

A novel method is proposed of estimating market concentration for the census case in which firms are grouped into size classes and all that is known about the firms in each category is their number and aggregate size. The formula arises as a way of applying an alternative expression for the concentration ratio based upon the original and first moment size distributions of firms. The semi-parametric technique, which includes a method of interval as well as point estimation, is derived, applied and validated using actual and simulated data. It is anticipated that the estimator will be of use in competition analysis as well as in academic research.
