Suboptimal herd performance amplifies the spread of infectious disease in the cattle industry

Farms that purchase replacement breeding cattle are at increased risk of introducing many economically important diseases. The objectives of this analysis were to determine whether the total number of replacement breeding cattle purchased by individual farms could be reduced by improving herd performance and to quantify the effects of such reductions on the industry-level transmission dynamics of infectious cattle diseases. Detailed information on the performance and contact patterns of British cattle herds was extracted from the national cattle movement database as a case example. Approximately 69% of beef herds and 59% of dairy herds with an average of at least 20 recorded calvings per year purchased at least one replacement breeding animal. Results from zero-inflated negative binomial regression models revealed that herds with high average ages at first calving, prolonged calving intervals, abnormally high or low culling rates, and high calf mortality rates were generally more likely to be open herds and to purchase greater numbers of replacement breeding cattle. If all herds achieved the same level of performance as the top 20% of herds, the total number of replacement beef and dairy cattle purchased could be reduced by an estimated 34% and 51%, respectively. Although these purchases accounted for only 13% of between-herd contacts in the industry trade network, they were found to have a disproportionately strong influence on disease transmission dynamics. These findings suggest that targeting extension services at herds with suboptimal performance may be an effective strategy for controlling endemic cattle diseases while simultaneously improving industry productivity

Moral choice in an agency framework: The search for a set of motivational typologies

Moral choice, as a precursor to behaviour, has an important influence on the success or failure of business entities. According to Rest, 1983, Morality, Moral Behavior and Moral Development (John Wiley & Sons, New York), moral choice is prompted, amongst other things, by a motivational component. With this in mind, data obtained from a sample of four hundred financial sector operatives, employed in a rapidly developing region of China, was used to construct a relatively stable set of motivational typologies which could be used to predict choice within an agency-based context. A non-egoist version of the agency theory was developed, which permitted the modelling of alternative heuristic patterns. Altruists and persons identified as bordering on the verge of being classified as psychological egoists, refused to reorganize their motives when responding to a problem that included both moral hazard and adverse selection criteria. It was also possible to identify certain personal and contextual issues which discriminated between the typologies

Dishonesty in the Classroom: The Effect of Cognitive Dissonance and the Mitigating Influence of Religious Commitment

A controlled experiment was conducted with a cohort of graduate accounting students, which involved a mild form of deception during a class ethics quiz. One of the answers to a difficult question was inadvertently revealed by a visiting scholar, which allowed students an opportunity to use the answer in order to maximise test scores and qualify for a reward. Despite an attempt to sensitize students prior to the test to the importance of moral codes of conduct, a high incidence of cheating was reported. Students who took the opportunity to cheat were more condoning of the behaviour compared to control group members and this difference in attitudes was consistent regardless of the intensity of the issue specified in the survey. The cognitive dissonance associated with the academic dishonesty is believed to reveal behavioural orientations that reflect conscious and unconscious desires to alleviate the discomfort associated with the behaviour by attempting to condone it. This inappropriate behaviour appears to attract students professing no religious faith and is significantly influenced by the reported level of religious commitment
