British Educational Research Journal, EarlyView.Abstract Many nations experience recurring shortages of teachers in particular subjects, prompting concerns that pupils' education is suffering as a result. Researchers have responded by generating a sizable literature on the reasons for which people enter and exit the teaching profession.

Business Strategy and the Environment, EarlyView.ABSTRACT Quantitative and perceptual studies have been used to define and model sustainable tourist behaviour in past years, but few studies have undertaken qualitative research of actual behaviour to delve deeper into understanding the different classifications of such behaviour. This research employed a three‐phase design, comprising a pretrip survey,

, 2013 We consider the formation of solar infrared (2-6 micron) rovibrational bands of carbon monoxide (CO) in CO5BOLD 3D convection models, with the aim to refine abundances of the heavy isotopes of carbon (13C) and oxygen (18O,17O), to compare with direct ...

On feedback in network source coding [PDF]
, 2009 We consider source coding over networks with unlimited feedback from the sinks to the sources. We first show examples of networks where the rate region with feedback is a strict superset of that without feedback.

Off‐Grid Solar Systems: An Experimental Work and Systematic Techno‐Economic Analysis
Energy Science &Engineering, EarlyView.In the study mentioned above, experimental monitoring and economic evaluation of two off‐grid PV systems were conducted using a low‐cost data logger. The results suggest that basic DC systems are economically feasible compared to grid power, but that AC systems require further cost‐cutting to achieve financial viability.

Performance of condensing and evaporating characteristics of an auto-refrigerating cascade system
Advances in Mechanical Engineering, 2019 The condensing and evaporating characteristics of an auto-refrigerating cascade cycle employing ternary zeotropic mixture R600a/R23/R14 are studied in this article. When the outlet temperature of condenser is 300 K, the composition ratio of R600a/R23/R14

Exploring the Impedance Spectroscopy in Hole‐Conductor‐Free Mesoscopic Perovskite Solar Cells
Progress in Photovoltaics: Research and Applications, EarlyView.This study employs impedance spectroscopy (IS) to investigate the carrier dynamics of printable perovskite solar cells (p‐MPSCs). The exceptional stability of p‐MPSCs enables reliable IS measurements under various conditions. We develop an equivalent circuit model to analyze the IS data, linking each circuit element to specific dynamic processes.
