The effects of rate and amount of reinforcement on the speed of the pacemaker in pigeons’ timing behavior

The peak-time procedure was used with pigeons to explore assumptions of two models of time perception: scalar expectancy theory (SET) and behavioral theory of timing (BeT). Conditions 1A and 1B varied fixed-interval duration to change rate of reinforcement. Condition 2 varied hopper duration in order to manipulate arousal level. Condition 3 held constant the interval to be timed (fixed-interval duration) but varied rate of reinforcement by interspersing trials in which only the chamber light came on for a duration equal to the fixed interval. Results from Conditions 1A, 1B, and 3 show that the speed of the pacemaker (1/τ) was directly proportional to the rate of reinforcement, thus supporting BeT. Manipulations of the hopper duration had no effect on the timing process.     

They have gone,and now what? Understanding re-enrolment patterns in the Catalan public higher education system

Studies of student re-enrolment patterns in higher education constitute, along with traditional studies of persistence and dropout, a key element for improving the quality of higher education institutions. However, these studies tend to be limited as they are centred on a single institution, due to the lack of national-scale data sets for monitoring students between different institutions. Using a longitudinal population-based data set provided by the Catalan University Assurance Agency (AQU), which includes information records on 21,473 undergraduate students, this paper aims to develop and test an exploratory model of student re-enrolment, specifically in the Catalan public university system. We are not only interested in student re-enrolment, but also in whether they do so during the first year after dropout or in the same area of knowledge. Results from logistic regression analysis revealed that although most students return to the university system in the first year after dropout, many of these change to a different area of knowledge, which is clear evidence of dysfunctional and inefficient guidance systems and university entrance. Findings provide a more accurate and complete picture of student re-enrolment behaviour and suggest the need to develop targeted policies to improve the efficiency and effectiveness of our university systems.     

The role of Action Learning in supporting cross-cultural adaptation of international students

ABSTRACT

We explore the reflections of a lecturer using Action Learning (AL) meetings for the dissertation module on a one-year Master’s programme with a predominantly international student cohort. We focus on two concerns: to what extent does AL mitigate against the negative experiences of cross-cultural adaptation? And can we surface and share the learning that occurs when (international) scholars become practitioners and practitioners become (international) scholars? In the AL groups, many students seem more at ease with themselves, others and content in AL meetings than in other sessions. We scrutinised AL and our AL meetings to explore what makes it different and perhaps a better learning experience for the international student. This paper emerged following discussions with David, an e-learning and pedagogic specialist. Before continuing, note that there are two terms discussed in the literature: ‘cross-cultural adjustment’ and ‘cross cultural adaptation’. ‘Adjustment’ refers to minor changes to cope with when facing a new situation, ‘adaptation’ to larger scale changes [Haslberger, Arno, and Chris Brewster. 2007. “Domains of Expatriate Adjustment with Special Emphasis on Work.” Presented at the Cadiz University’s VI International Workshop on Human Resource Management, Jerez, Spain]. We suggest that AL be used more often and earlier with international students.     

Children in care or in need: educational progress at home and in care

ABSTRACT

By age 16 the attainment of most children in or on the edge of out of home care has fallen well behind the average for their age. This paper uses the English National Pupil Database to examine how much of this falling behind occurs before the age of seven, and how any subsequent decline relates to time in care as against time outside it. We compare the previous progress of three groups of 16-year-olds: 5175 looked after by the state (CLA), 17,392 in need but not in care (CIN), and 22,567 children matched with the CLA or CIN on initial attainment, special educational needs, and eligibility for free school meals. We found that the attainment of the CIN and those CLA not yet in care was around one standard deviation below the cohort average at age seven. It then fell relative to their peers while their rate of unauthorised absences and exclusions grew. Removal from home to care appeared to halt or greatly reduce this decline but did not, on average, reverse it. We conclude that educational interventions for CLA should also include CIN, start before seven, target both school and family, and exploit the educational opportunity which care provides.     

Academic stress of international students attending U.S. universities

This study investigated factors associated with the academic stress experienced by international students (N=412) attending graduate school in the United States. The study was grounded in a cognitive framework in which academic stress is understood as the consequence of students' appraisal of the stressfulness of role demands and their perception of their ability to cope with those demands. These two appraisals, in turn, were posited to be a function of cultural distance, students' social support network, and their role competencies. Results indicated that the primary determinants of the two types of appraisals differed. While self-perceived English-language skills and, to a lesser degree, cultural distance were the predictors of primary appraisal, self-perceived English-language, academic, and problem-solving skills and social support network were the main determinants of secondary appraisal. Implications for how universities might work more effectively with international students are discussed.
