Hurdle-jump responding in the rat as a function of conspecific odor of reward and nonreward

A hurdle-jump escape response was employed to assess the laboratory rat’s aversion or attraction to different types of conspecific odor. Odorant donor subjects received 112 runway acquisition trials on a continuous reward schedule followed by 32 extinction trials, 112 acquisition trials on a 50% schedule of reward and nonreward followed by 32 extinction trials, or 144 “neutral” trials with no reward in the alley. Different groups of test subjects escaped from odor excreted by odorant subjects on (a) nonrewarded acquisition and extinction trials, (b) rewarded trials during continuous reinforcement, (c) rewarded trials during partial reinforcement, or (d) neutral trials; others escaped from a clean box. The principal findings were: (1) significant aversion to “odor of nonreward” appeared after the donor odorants had received 12 exposures to reward; (2) production of odor of nonreward by odorant subjects changed as a function of training experience with reward; (3) after repeated exposure to odor of nonreward, the escape response habituated; (4) greater or different odor excretion in extinction resulted from subjects trained on a continuous reward schedule than on a partial reward schedule. Relationships of the data to frustration theory were discussed, assuming that inferred differences in production of odor reflect differences in frustration reaction.     

'The Kids are Doing All Right': Differences in parental satisfaction,expectation and attribution in St Petersburg,Sunderland and

Comparative studies of attitudes in different countries have resulted in the claim that parents in the USA and England tend to have unrealistically positive views of their children's schools and academic performance. Low expectations, together with a belief in the importance of natural ability, it has been argued, lead to low standards and reduce striving to succeed. The present study builds upon earlier investigations of children's attitudes, beliefs and behaviours in Sunderland, Eastern Kentucky and St Petersburg by surveying parental perspectives. Findings from these three regions reinforce earlier findings about English and American complacency and the more demanding nature of the Russian context. In line with our earlier studies, and contrary to the suggestion of a number of writers, an emphasis upon effort, rather than ability, was a strong feature of the English and American responses, although it is pointed out that such beliefs may not actually result in high work rates. The paper concludes by suggesting that the important role of parents in instilling important attitudes and behaviours in their children is undermined by the current emphasis upon schools as fundamentally responsible for ensuring high levels of achievement.     

Molecular thermodynamics for cell biology as taught with boxes

Thermodynamic principles are basic to an understanding of the complex fluxes of energy and information required to keep cells alive. These microscopic machines are nonequilibrium systems at the micron scale that are maintained in pseudo-steady-state conditions by very sophisticated processes. Therefore, several nonstandard concepts need to be taught to rationalize why these very ordered systems proliferate actively all over our planet in seeming contradiction to the second law of thermodynamics. We propose a model consisting of boxes with different shapes that contain small balls that are in constant motion due to a stream of air blowing from below. This is a simple macroscopic system that can be easily visualized by students and that can be understood as mimicking the behavior of a set of molecules exchanging energy. With such boxes, the basic concepts of entropy, enthalpy, and free energy can be taught while reinforcing a molecular understanding of the concepts and stressing the stochastic nature of the thermodynamic laws. In addition, time-related concepts, such as reaction rates and activation energy, can be readily visualized. Moreover, the boxes provide an intuitive way to introduce the role in cellular organization of "information" and Maxwell's demons operating under nonequilibrium conditions.     

International students’ use of social network services in the new culture: a case study with Korean youths in the United States

In the United States, international students, especially from Asia, have reportedly experienced difficulty adjusting to their new life and culture. Little research has been done to understand the role of social network service (SNS)s, including instant messaging, blogs, chatting websites, and email on these students. Korean students are the largest international student group in the United States and were selected for the qualitative case study. Results showed that the participants used SNSs in various ways for their emotional well-being and for academic purposes.     

Reflections on a Decade of Global Rankings: what we've learned and outstanding issues

Ten years after the first global rankings appeared, it is clear that they have had an extraordinary impact on higher education. While there are fundamental questions about whether rankings measure either quality or what's meaningful, they have succeeded in exposing higher education to international comparison. More so, because of the important role higher education plays as a driver of economic development, rankings have exposed both an information deficit and national competitiveness. Accordingly, both nations and institutions have sought to maximise their position vis-á-vis global rankings with positive and perverse effects. Their legacy is evident in the way rankings have become an implicit — and often explicit – reference point for policymaking and higher education decision-making, and have reinforced an evaluative state's over-reliance on quantitative indicators to measure quality. They are embedded in popular discourse, and have informed the behaviour of many stakeholders, within and outside the academy. This paper reflects on three inter-related issues; i) considers the way rankings have heightened policy and investment interest in higher education, ii) discusses whether the modifications to rankings have resolved some of the questions about what they measure, and iii) looks at how rankings have influenced stakeholder behaviour. Finally, the paper reflects on what we have learned and some outstanding issues.     

Attitudes toward Face-to-Face and Online Counseling: Roles of Self-Concealment,Openness to Experience,Loss of Face,Stigma, and Disclosure Expectations among Korean College Students

This study examined attitudes toward face-to-face (f2f) and online counseling among 228 Korean college students. In addition, it tested a hypothesized model proposing that general propensities (i.e., self-concealment, openness to experience, and loss of face) would influence counseling-specific expectations (i.e., self-stigma and disclosure expectations), which, in turn, would predict attitudes toward f2f and online counseling. Findings mirrored the results of earlier studies revealing that self-concealment was negatively related to attitudes toward both f2f and online counseling, while openness to experience and disclosure expectations were positively related. However, whereas self-stigma was associated with negative attitudes toward f2f counseling, it was not related to attitudes toward online counseling. In addition, disclosure expectations accounted for f2f attitudes more than online attitudes.
