An understanding of the factors infuencing the human-animal relationship is relevant in the development of welfare interventions for working equids. However, the link between the psychological attributes of animal owners, such as empathy level and pain perception, and the welfare state of working horses is yet to be studied. Here, we assessed working horse owners' empathy, their perception of equine pain and how these relate to the welfare state of their horses. The relationship between empathy and perception of equine pain was also explored. One hundred owners of working horses were studied, along with their working horses (n = 127). Self-reported rating scales were used for measuring animal-oriented empathy, human-oriented empathy and owners' perception of equine pain; higher scores in the three scales indicated higher levels of empathy and higher perception of equine pain. An animal welfare index based on direct measures was applied where higher scores indicate a poorer welfare state. Most of the owners had high levels of empathy towards both animals and humans and a high perception of equine pain. According to the animal welfare index, 15.7% of horses had a poor welfare state. Higher levels of empathy and equine pain perception in owners were correlated with a better animal welfare condition, with owner's empathy level towards animals explaining over 60% of horses' welfare. Moreover, empathy towards animals was positively correlated with human-oriented empathy and perception of equine pain. We therefore suggest that strategies oriented to improve welfare of working horses should consider education programmes aimed at promoting the development of empathy in caretakers.

Amorphous titanium dioxide monoliths doped with brilliant green (BG) were synthesized by the sol-gel process. The optical properties of the monoliths were characterized by Photoacoustic Spectroscopy and Photoluminescence Spectroscopy. The absorption spectra for the BG-doped TiO2monoliths exhibited two well defined absorption regions: a band below 400 nm corresponding to TiO2absorption and three absorption bands centered at 424 nm, 588 nm, and 632 nm due to brilliant green. While the undoped TiO2monoliths showed no luminescence, the doped samples showed a strong luminescence band at 673 nm, which increased its intensity for increasing organic dye doping.
