Too much of a good thing? A multilevel examination of listening to music at work.

Music listening has proliferated in the workplace, yet its effects have been overlooked, and classic investigations offer conflicting results. To advance our understanding, we draw from self-regulation and resource allocation theories to suggest that listening to music has curvilinear effects on attentional focus and performance on work tasks and that willpower belief is a key boundary condition. We test these hypotheses across three studies: a pilot study of 108 employees from a software company who took part in a 2-week experience-sampling methodology study and self-rated their music listening and performance, a laboratory study (Study 1) of 252 undergraduate students in which task attentional focus and objective performance on proofreading tasks were captured across repeated trials while listening to music, and a 3-week experience-sampling methodology study (Study 2) of 247 employees that included a within-person manipulation of music listening (little to no music vs.

An Observational Study of Skeletal Malformations in Four Semi-Intensively Reared Carp Species.

Cyprinids include some of the most widely farmed freshwater species. The aim of this study was to assess the incidence of skeletal malformations in carp species reared in semi-intensive systems in Albania: common carp (), silver carp (), grass carp () and bighead carp (). The common carp fingerlings had a mean total length of 28.

Hemp seed ( L.) cake as sustainable dietary additive in slow-growing broilers: effects on performance, meat quality, oxidative stability and gut health.

Hemp seed cake (HSC) ( L.) is a rich source of polyunsaturated fatty acids, high-quality proteins and essential amino acids. The aim of this study was to evaluate the effects of dietary inclusion of HSC on growth performance, meat quality traits, fatty acids profile and oxidative status, and intestinal morphology in slow-growing broilers.

Effect of rearing system (free-range vs cage) on gut and muscle histomorphology and microbial loads of Italian White breed rabbits.

Objective: The growing consumers' interest on animal welfare has raised the request of products obtained by alternative rearing systems. The present study was conducted to assess the influence of housing system on gut and muscle morphology and on microbial load in rabbits reared under free-range (FR) and cage system (CS).

Methods: A total of forty weaned (35 days of age) male Italian White breed rabbits were allotted according to the rearing system, and at 91 days of age were randomly selected and slaughtered for the morphological evaluation of tissue from duodenum and longissimus lumborum.
