Optimum Replacement Policies for the Control of Subclinical Mastitis due to S.aureus in Dairy Cows

A dynamic program was used to establish the optimum replacement policy for dairy herds, taking into account subclinical mastitis caused by the bacteria Staphylococcus aureus. This particular pathogen is resistant to normal drug therapies and therefore culling is the major method of control. Methods are described to account for output losses due to yield loss and a reduction in milk price caused by extra somatic cells secreted into the milk by infected cows. Extra culling was justified in both infected and control herds in order to reduce the level of infection in the herd. The method described allows replacement policy to be treated as control expenditure rather than an output loss in the economic analysis of farm animal disease. This approach will become even more important as consumers demand an alternative to the prophylactic use of antibiotics in agriculture without compromising food quality and safety.     

Want to perfect your company's service? Use behavioral science.

It may seem like the topic of service management has been exhausted. Legions of scholars and practitioners have applied queuing theory to bank lines, measured response times to the millisecond, and created cults around "delighting the customer." But practitioners haven't carefully considered the underlying psychology of service encounters--the feelings that customers experience during these encounters, feelings often so subtle they probably couldn't be put into words. Fortunately, behavioral science offers new insights into better service management. In this article, the authors translate findings from behavioral-science research into five operating principles. First, finish strong: the ending is far more important than the beginning of an encounter because it's what remains in the customer's memory. Second, get the bad experiences out of the way early: in a series of events, people prefer to have undesirable events come first and to have desirable events come last. Third, segment the pleasure, combine the pain: since experiences seem longer when they are broken into segments, it's best to combine all the boring or unpleasant steps of a process into one. Fourth, build commitment through choice: people are happier when they believe they have some control over a process, particularly an uncomfortable one. And fifth, give people rituals and stick to them: most service--encounter designers don't realize just how ritualistic people are. Ultimately, only one thing really matters in a service a encounter--the customer's perception of what occurred. This article will help you engineer your service encounters to enhance your customers' experiences during the process as well as their recollections of the process after it is completed.     

Unity in the Social Thought of Adolph Lowe: A Review of "Essays in Political Economics: Public Control in a Democratic Society"

Abstract . From the economist Adolph Lowe's voluminous-writings, Allen Oakleyh has selected eight essays which present the gist of Lowe's thought. It unifies his structural analyses and his instrumental analyses into the system Lowe calls “Political Economics.” This pre-orders desired ends or effects and then determines or applies goal-adequate means to achieve these ends. Lowe's Essays in Political Economics sketches the economic paradigm by which he expands the evolutionary way of thinking from the subject —economic behavior— to the object, the socioeconomic world. He argues that instability is fundamental, basic and inherent in contemporary industrial capitalism as it has evolved physically, technologically and socially and stability can be restored by an approach which reverses the continuum to end-means. He holds that if the world evolves, and it does, so must the goal-adequate methods and instrumentalities to deal with it.     

Supporting Communities in Transition: The Impact of the Armenian Social Investment Fund

The Armenian Social Investment Fund supports communities' effortsto improve local infrastructure during Armenia's economic transitionaway from central planning, financing community-designed and-implemented projects to rehabilitate primary schools, watersystems, and other infrastructure. This article considers thetargeting, household impact, and community effects of the socialfund's activities. It relies on a nationally representativehousehold survey, oversampled in areas where the social fundwas active. Using propensity and pipeline matching techniquesto control for community self-selection into the social fund,it evaluates the household effects of rehabilitating schoolsand water systems. The results show that the social fund reachedpoor households, particularly in rural areas. Education projectsincreased households' spending on education significantly andhad mild effects on school attendance. Potable water projectsincreased household access to water and had mild positive effectson health. Communities that completed a social fund projectwere less likely than the comparison group to complete otherlocal infrastructure projects, suggesting that social capitalwas expended in these early projects. By contrast, communitiesthat joined the social fund later and had not yet completedtheir projects took more initiatives not supported by the socialfund.     

Eco-labeling motorcoach operators in the North American travel tour industry: analyzing the role of tour operators

Tourist transportation is a major contributor of emissions and environmental pollutants. Eco-labels can encourage more sustainable tourism by informing consumers’ purchasing decisions, while utilizing market forces to initiate environmental responsibility among competing firms. The Green Coach Certification pilot eco-label program was introduced to the motorcoach industry in 2009 as part of a university research program. Although the literature addresses relationships between end-user consumers and eco-labels, little research has been published on mid-supply chain actors and tourism eco-labels. Tour operators are intermediaries between end-users and motorcoach operators and are important potential consumers of eco-labeled transportation services. To understand the role of tour companies as both consumers and providers of green services and eco-labeled products, a survey was administered to North American tour operators. Results demonstrate tour operator interest in a tourism transportation eco-label; however, this interest may be secondary to traditional considerations like price, reputation for safety and service, and previous partnerships. Ninety percent of tour operators indicated that environmental practices held some importance when choosing a transportation provider; approximately 50% said they would pay between 1% and 5% more for an eco-labeled coach company. Findings have important implications for the design and implementation of eco-labeling programs for sustainable tourism and transportation.
