Investigating the influence of music tempo on arousal and behaviour in laboratory virtual roulette

A number of studies indicate that fast music influences performance in everyday activities including shopping and gambling, but the mechanisms through which this effect is realised are not well understood. This study investigates whether fast tempo music influences gambling via an effect on arousal using a laboratory virtual roulette task. One hundred and forty-four participants played virtual roulette whilst listening to fast tempo, slow tempo or no music. Music tempo alone did not influence betting speed, expenditure or risk-taking. Furthermore tempo did not influence participants’ physiological or subjective arousal levels, nor participants’ opinions of the musical stimuli in terms of liking, familiarity, fit or its ability to aid concentration. Our findings suggest that there are some circumstances under which the effect of music tempo does not operate and therefore provides an insight into the limits of music tempo as an explanation for music effects on behaviour. This study has implications for the way that musical characteristics are operationalised in future research into music’s effects on behaviour

Description of the pig production systems, biosecurity practices and herd health providers in two provinces with high swine density in the Philippines

A cross-sectional study was conducted between October 2011 and March 2012 in two major pig producing provinces in the Philippines. Four hundred and seventy one pig farms slaughtering finisher pigs at government operated abattoirs participated in this study. The objectives of this study were to group: (a) smallholder (S) and commercial (C) production systems into patterns according to their herd health providers (HHPs), and obtain descriptive information about the grouped Sand C production systems; and (b) identify key HHPs within each production system using social network analysis. On-farm veterinarians, private consultants, pharmaceutical company representatives, government veterinarians, livestock and agricultural technicians, and agricultural supply stores were found to be actively interacting with pig farmers. Four clusters were identified based on production system and their choice of HHPs. Differences in management and biosecurity practices were found between Sand C clusters. Private HHPs provided a service to larger C and some larger S farms, and have little or no interaction with the other HHPs. Government HHPs provided herd health service mainly to S farms and small C farms. Agricultural supply stores were identified as a dominant solitary HHP and provided herd health services to the majority of farmers. Increased knowledge of the routine management and biosecurity practices of S and C farmers and the key HHPs that are likely to be associated with those practices would be of value as this information could be used to inform a risk-based approach to disease surveillance and control.

Prevalence and risk factors associated with gross pulmonary lesions in slaughtered pigs in smallholder and commercial farms in two provinces in the Philippines

A cross-sectional study of lungs from 1,887 randomly selected pigs from 471 farms from two provinces in the Philippines was carried out to estimate the prevalence of gross pathological lesions, identify potential risk factors and spatial clustering associated with high lung or pleurisy score farms. Lungs from pigs were scored at slaughter. Interviews with the farm managers were conducted to collect information about farm management and biosecurity practices. Of lungs examined, 48% had a lung score above 6 (maximum was 55) and 22% showed pleurisy. When data were aggregated at the farm level, commercial farms were at higher risk of being high lung score farms and high pleurisy farms compared to smallholder farms (
