Building critically on Sartre, the gaze in Lacan and Merleau-Ponty is part of the technical apparatus used to describe the foundation, production, and reproduction of the subject. I will begin by discussing the role of visual perception in subject-formation in their respective work, differentiating between the Merleau-Pontian notion of the ＂gaze of the world,＂ i.e., the ways in which things cast their gaze upon us, and the Lacanian gaze as a manifestation of the scopic drive. Through an analysis of anamorphosis I will show （1） how the gaze evades the spectator, （2） what the relationship of the gaze is to the object petit a as the object of the scopic drive, and （3） how both Merleau-Ponty and Lacan require a movement that precedes and destabilizes the subject of intentional consciousness.展开更多

In the information age, the innovative technologies of mobile devices make the dramatical changes in ways of teaching and learning （Atkinson, 2011; Bierstaker, Janvrin ＆ Lowe, 2014, Pittaway, 2012; Yang ＆ Che, 2015）. The focus of this study aims to examine ESP college students＇ English learning performance by using Context Aware Mobile Situated Learning （CAMSL） in Tourism and Hospitality Management field and other majors. The mixed research method is conducted for data collection and analysis. The quantitative data are collected by examining students＇ learning performance; the qualitative data are allowed to understand the students＇ perspective toward their role in using the CAMSL with Tourism related content. Eight-three students are randomly selected and divided into two groups： 42 students are assigned in the experimental group A （CAMSL）, and 41 students are assigned in control group. Two groups of students receive pretest and posttest to examine their English performance. Besides, twenty students from group A and B are selected for online survey. The survey is mailed directly to students＇ email account. Results represented by using CAMSL show the significant improvement on students＇ learning performance. In addition, the survey data indicate the benefits of using the CAMSL help students enhance their academic discourse, develop their learned knowledge to represent their profession, use English properly to speak themselves up, and provide the effectiveness of obtain domain knowledge in future workplace.展开更多
