A note on loan market equilibrium when some borrowers are optimistic

We study a loan market equilibrium in which some borrowers are optimistic and banks face imperfect competition. We show that the presence of optimistic borrowers reduces the interest rate paid by safe borrowers and increases the interest rate paid by risky borrowers. But it has no net impact on the banks' profits.Banking, optimistic borrowers, imperfect competition

The effect of CEO overconfidence on bank risk taking

Recent studies document that some CEOs are overconfident. In this note, we examine the effect of CEO overconfidence on bank risk taking. We measure CEO overconfidence using press data, and bank risk taking using the standard deviation of stock returns. Controlling for a number of CEO- and bank-specific variables, we find that banks managed by overconfident CEOs take more risk.CEO, overconfidence, bank, risk taking

Give Students Autonomy in the Use of Break Time in Conformity with the Principles of Humanistic Education

Humanistic education (also known as person-centered education) is a learning theory based on humanistic psychology, aiming to promote the development of the learner as a “whole person.” Various aspects such as the intellect, social and emotional skills, and artistic and practical capabilities of the student are all important considerations in the humanistic approach to education (Zhang, 2010). It places a great deal of emphasis on students’ choice and control over the course of their education. Students are encouraged to make choices that range from day-to-day activities to goal settings. According to Rogers, one of the founders of humanistic psychology as well as the humanistic learning theory, the primary purpose of education is to train the student to want and know how to learn, and the ability to learn should relate to the fulfillment of other needs (as cited in Xie, 2016)

Quantum transport properties of ultrathin silver nanowires

The quantum transport properties of the ultrathin silver nanowires are investigated. For a perfect crystalline nanowire with four atoms per unit cell, three conduction channels are found, corresponding to three $s$ bands crossing the Fermi level. One conductance channel is disrupted by a single-atom defect, either adding or removing one atom. Quantum interference effect leads to oscillation of conductance versus the inter-defect distance. In the presence of multiple-atom defect, one conduction channel remains robust at Fermi level regardless the details of defect configuration. The histogram of conductance calculated for a finite nanowire (seven atoms per cross section) with a large number of random defect configurations agrees well with recent experiment.Comment: 4 pages, 6 figure
