Aged Asphalt

In this study, the aged asphalt binder and mixture were laboratory prepared through short-term ageing testing and long-term ageing testing. Firstly, the effect of rejuvenator on physical properties of aged asphalt binders was investigated. In addition, a series of laboratory tests were performed to evaluate the influence of ageing and rejuvenator content on the mechanical properties, durability and dynamic characteristics of asphalt mixtures. Physical test results of asphalt binder testified that rejuvenator used can efficiently recover the aged asphalt binder. However, the effect of ageing and rejuvenator content exhibits different trends depending on the physical property tests conducted. Moreover, artificially aged asphalt mixture with rejuvenator has better ability to resist moisture damage and ravelling. In addition, the ITSR value is more suitable to evaluate the moisture susceptibility for asphalt recycling. Although rejuvenator improves the thermal cracking resistance and fatigue property of aged asphalt mixture, rejuvenated mixture shows greater modulus and inferior ability to resist reflective cracking than the unaged mixture. Moreover, rejuvenated mixture shows less dependence on frequency at high temperature regions and stronger dependence at low temperature regions compared to unaged and long-term aged mixtures.

ABSTRACT The alkaloid caffeine and the amino acid arginine are present as secondary compounds in nectars of some flower species visited by pollinators. Each of these compounds affects honeybee appetitive behaviours by improving foraging activity and learning. While caffeine potentiates responses of mushroom body neurons involved in honeybee learning processes, arginine acts as precursor of nitric oxide, enhancing the protein synthesis involved in memory formation. Despite existing evidence on how these compounds affect honeybee cognitive ability individually, their combined effect on this is still unknown. We evaluated acquisition and memory retention in a classical olfactory conditioning procedure, in which the reward (sucrose solution) contained traces of caffeine, arginine or a mixture of the two. The results indicate that the presence of the single compounds and their most concentrated mixture increases bees' learning performance. However, memory retention, measured in the short and long term, increases significantly only in those treatments offering combinations of the two compounds in the reward. Additionally, the most concentrated mixture triggers a significant survival rate in the conditioned bees. Thus, some nectar compounds, when combined, show synergistic effects on cognitive ability and survival in an insect.

AbstractDopamine and serotonin are important modulators of synaptic plasticity and their action has been linked to our ability to learn the positive or negative outcomes or valence learning. In the hippocampus, both neuromodulators affect long-term synaptic plasticity but play different roles in the encoding of uncertainty or predicted reward. Here, we examine the differential role of these modulators on learning speed and cognitive flexibility in a navigational model. We compare two reward-modulated spike time-dependent plasticity (R-STDP) learning rules to describe the action of these neuromodulators. Our results show that the interplay of dopamine (DA) and serotonin (5-HT) improves overall learning performance and can explain experimentally reported differences in spatial task performance. Furthermore, this system allows us to make predictions regarding spatial reversal learning.

Purpose Field trips can change students’ attitudes and improve their learning performance, but they have rarely been investigated in logistics education research. The purpose of this paper is to present the findings from field trips that were designed to increase students’ knowledge of sustainable transport as well as to change their attitudes and behavioral intentions. Design/methodology/approach A total of 104 logistics students participated in this longitudinal panel study. Non-parametric statistical tests were used to test for significant effects. Findings Field trips build students’ knowledge, improve their attitudes and increase their behavioral intentions to use sustainable transport modes in the short and in the long term. Gains in knowledge exceed the results expected from traditional learning theories. Gender and school type are important moderating variables. Gender did not play an important role for knowledge gains, but for attitude and behavioral intentions. Research limitations/implications More research is needed to generalize the findings to other populations and longitudinal panel studies are necessary to investigate a long-term effect of field trips. Practical implications Field trips are an effective means for successful knowledge transfer and are suitable to trigger attitudinal and behavioral changes. The involvement of practitioners and the hands-on experience ensure that students combine theoretical with practical knowledge. Originality/value This is the first longitudinal panel study that investigates the effects of logistics field trips, which were developed collaboratively by industry, educational and research institutions.

English Instruction

It is an important but complicated issue to investigate the long-term effect of the intelligent Web-based English instruction system CSIEC on students' learning performance with satisfying reliability and validity. This chapter introduces three years' process of the design and implementation of English instruction in four diverse high schools with the CSIEC system (i.e. the integration of CSIEC system into English instruction in four high schools: the project team organization, the survey and user needs analysis before the project implementation, system design, programming and test, the process of CSIEC's integration into English classes, and phase meetings). The management issues of the project were thought to guarantee its successful implementation in four different high schools located in distant provinces in China.
