Success in higher education: the challenge to achieve academic standing and social position     

James Life 《Interactive Learning Environments》2013,21(6):683-695

When students look at their classmates in the classroom, consciously or unconsciously, they see competitors both for academic recognition and social success. How do they fit in relation to others and how do they succeed in achieving both? Traditional views on the drive to succeed and the fear of failure are well known as motivators for achieving academic success but is it that simple a dichotomy? Do students also view success through a fear of success and a purposeful intent to fail – referred to in this text as the drive to fail? Students recognize the importance of social position in class but how is this perceived and will they sacrifice social position for academic standing or vice versa? This paper considers these issues by analyzing the results of a student survey and opinions offered by the students. The discussion considers the survey, academic standing, social position, cultural variables, perception of success and failure, and concluding comments.  相似文献

Suffering in sport: why people willingly embrace negative emotional experiences     

Michael S. Brady 《体育哲学杂志》2019,46(2):115-128

ABSTRACT

Nearly everyone agrees that physical pain is bad. Indeed, if anything merits the status of a platitude in our everyday thinking about value, the idea that pain is bad surely does. Equally, it seems clearly true that emotional suffering – despair, loneliness, grief, disappointment, guilt, shame, lovesickness, and the like – are all bad as well. We are strongly inclined to pity and feel sorry for those who suffer emotionally in these ways; we are motivated, at least some of the time, to do what we can to alleviate their suffering. Given this, it might seem curious that pain and suffering are so integral to sport – whether one is a participant or a spectator. There’s nothing particularly puzzling about pain and suffering that is inadvertently related to sport – as when an athlete injures her hamstring and has to miss her chance at Olympic glory, or when supporters face the misery of getting up at 6am because an away game has been scheduled to start at noon. But there does seem to be something curious about the extent to which pain and suffering are voluntarily embraced by participants and spectators, as the quotation from Nick Hornby aptly illustrates. Why do people willingly engage in something that brings about so much suffering? In this paper, I’ll attempt to answer this question.¹  相似文献   

行政法治视野中的"聘任县长"--关于县人大常委会"聘任"副县长行为的反思     

何景春 《湖北广播电视大学学报》2006,23(1):110-112

国家公务员产生中的聘任制是行政机关通过聘任方式将非国家公务员系统的公民录用为国家公务员的制度。县级人大常委会作为聘任国家公务员的适格主体,于法无据。强调“特殊环境下的特殊形式”,是对法治行政的极大的破坏,既不符合科学发展观,也与政治文明相背离。  相似文献

There’s something about Mary: The moral value of things <Emphasis Type="Italic">qua</Emphasis> information objects     

Kenneth?Einar?HimmaEmail author 《Ethics and Information Technology》2004,6(3):145-159

Luciano Floridi argues that every existing entity is deserving of at least minimal moral respect in virtue of having intrinsic value qua information object. In this essay, I attempt a comprehensive assessment of this important view as well as the arguments Floridi offers in support of it. I conclude both that the arguments are insufficient and that the thesis itself is substantively implausible from the standpoint of ordinary intuitions.  相似文献
