Constrained Firms, Not Subsistence Activities: Evidence on Capital Returns and Accumulation in Peruvian Microenterprises We investigate the returns to capital and capital accumulation using panel data of Peruvian micro enterprises (MEs). Marginal returns to capital are found to be very high at low levels of capital, but rapidly decreasing at higher levels. The dynamic analyses of capital accumu...

Speech perception often involves multisensory processing. Although previous studies have demonstrated visual [1, 2] and somatosensory interactions [3, 4] with auditory processing, it is not clear whether somatosensory information can contribute to the processing of audio-visual speech perception. This study explored the neural consequence of somatosensory interactions in audio-visual speech pro...

jumping on everyone else’s bandwagon, but has anyone ever evaluated the ‘science forecast’ ten years down the road? Nevertheless, this chapter provides several extremely useful starting points. The chapters are a bit heterogeneous in style, with some having glossaries and/or useful ‘future directions’ sections, whilst others do not. However, the quality of the chapters is consistently high, and...

The stability of the charge-stacked structure vis-à-vis the charge-alternate structure in the half-doped manganites is studied with a model that includes electronic kinetic energy, onsite and intersite Coulomb interactions, the Jahn–Teller energy, and the antiferromagnetic superexchange between the manganese core spins. It is shown that for a single zigzag chain, the electronic kinetic energy s...

Nayak et al have discussed in detail the inertial forces such as Gravitational, Coriolis-Lense-Thirring and Centrifugal forces in the Kerr-Newman Space-time in the Kerr-Newman Space-time. The main theme of this paper is to study the Gravitational and Centrifugal forces in the NUT-Kerr-Newman Space-time. Keywords—Gravitational Forces, Centrifugal Forces, Nut-KerrNewman, Space time.

Making use of the extended Ginzburg Landau theory, which includes the fourth order derivative term, we study the vortex state in a magnetic field parallel to the c axis. The vortex core structure is distorted due to this higher order term, which reveals the fourfold symmetry. Further, this distortion gives rise to the core interaction energy, which favors a square lattice tilted by 45 from the ...

In space missions, during the long isolation at extreme conditions for human health, it is of paramount importance to monitor vital parameters. One such parameter is the breathing rate. Indeed, several factors can induce some breathing anomalies during the sleep, which may cause apnea episodes. In order to act timely with the right therapy, an early diagnosis is required. Conventional devices a...

I, brought up in an authoritative educational and political system in Taiwan, and habituated in being dominated, was truly a positivist. I deeply believed that “there is a reality out there to be studied, captured, and understood.” (Denzin and Lincoln, 2000). Such belief had enhanced my blind worship of idealism as truth building in the pursuit of reality. It also had indirectly fostered the be...

The sensitivity of polarisation-asymmetry correlation experiments to charged currents of right-handed chirality contributing to allowed β-decay is considered in the most general context possible, independently of any type of approximation nor of any specific model for physics beyond the Standard Model of the electroweak interactions. Results are then particularised to general Left-Right Symmetr...

The metal-support interactions for a model silica-supported copper catalyst have been studied using temperature-programmed desorption, X-ray photoelectron and infrared reflection-absorption spectroscopies under ultrahigh vacuum conditions. The model catalyst support was prepared by synthesizing a thin SiO, film (_ 100 A) on a Mo(l10) surface. Copper was then evaporated onto the SiO, films. A sm...
