Classroom Management Training: Keeping New Teachers

Many new teachers begin their first day of school with a sense of idealism. They expect to make a difference in the lives of young students. However, many soon learn the challenges of classroom, behavior management and feel great stress. Can more classroom management training in college and pre-service, student-teaching strategies help these novice educators? This article asks education professionals and researchers to evaluate their teacher training programs and increase classroom management training

Seasonal changes and overwintering of endoparasites in the bat (Myotis lucifugus) in a Southeastern Wisconsin hibernaculum

Eight digenetic trematode species (Phylum Platyhelminthes, Subclass Digena), one cestode species (Phylum Platyhelminthes, Class Cestoidea) and three nematode species (Phylum Nematoda) were recovered from the little brown bat, Myotis lucifugus, at the Neda Mine hibernaculum in southeastern Wisconsin. Bats displayed a rich and diverse helminth fauna throughout the year. Statistically significant seasonal variation was observed for two digenetic trematodes. Mean intensities and prevalence of parasites were highest in autumn and spring and lowest in summer. Highest species diversity occurred in autumn. Greater intensity and prevalence in autumn and spring were correlated with bat swarming and emergence patterns, behavioral phenomena which would also produce a more heterogeneous assemblage of parasites during these times of year. Myotis lucifugus retained a large and varied population of parasites throughout eight months of hibernation

TRADABLE PERMITS FOR CONTROLLING NITRATES IN GROUNDWATER AT THE FARM LEVEL: A CONCEPTUAL MODEL

Nitrate contamination of municipal and domestic well water supplies is becoming an increasing problem in many rural and urban areas, raising the cost of providing safe drinking water. The objective of this paper is to describe a marketable permit scheme that can effectively manage nitrate pollution of groundwater supplies for communities in rural areas without hindering agricultural production in watersheds. They key to implementing this scheme is being able to link nitrate leaching from nitrogen fertilizer applied to crops at a farm to nitrate levels measured at a drinking water well.agriculture, groundwater pollution, leaching, nitrates, pollution trading, Environmental Economics and Policy,

The complete amino acid sequence of 3-dehydroquinate synthase of Escherichia coli K 12

AbstractThe complete amino acid sequence of the Escherichia coli 3-dehydroquinate synthase has been determined by a combined nucleotide and direct amino acid sequencing strategy. E. coli 3-dehydroquinate synthase is 362 amino acids long and has a calculated Mr of 38 880. Analysis of the aroB nucleotide sequence and its 5'- and 3'-flanking regions has identified the aroB promoter elements and a possible 3'-terminator site

Feline immunodeficiency virus (FIV) infection in domestic pet cats in Australia and New Zealand: Guidelines for diagnosis, prevention and management

Despite the passage of over 30 years since its discovery, the importance of feline immunodeficiency virus (FIV) on the health and longevity of infected domestic cats is hotly debated amongst feline experts. Notwithstanding the absence of good quality information, Australian and New Zealand (NZ) veterinarians should aim to minimise the exposure of cats to FIV. The most reliable way to achieve this goal is to recommend that all pet cats are kept exclusively indoors, or with secure outdoor access (e.g., cat enclosures, secure gardens), with FIV testing of any in-contact cats. All animal holding facilities should aim to individually house adult cats to limit the spread of FIV infection in groups of animals that are stressed and do not have established social hierarchies. Point-of-care (PoC) FIV antibody tests are available in Australia and NZ that can distinguish FIV-infected and uninfected FIV-vaccinated cats (Witness™ and Anigen Rapid™). Although testing of whole blood, serum or plasma remains the gold standard for FIV diagnosis, PoC testing using saliva may offer a welfare-friendly alternative in the future. PCR testing to detect FIV infection is not recommended as a screening procedure since a negative PCR result does not rule out FIV infection and is only recommended in specific scenarios. Australia and NZ are two of three countries where a dual subtype FIV vaccine (Fel-O-Vax® FIV) is available and offers a further avenue for disease prevention. Since FIV vaccination only has a reported field effectiveness of 56% in Australia, and possibly lower in NZ, FIV-vaccinated cats should undergo annual FIV testing prior to annual FIV re-vaccination using a suitable PoC kit to check infection has not occurred in the preceding year. With FIV-infected cats, clinicians should strive to be even more thorough than usual at detecting early signs of disease. The most effective way to enhance the quality of life and life expectancy of FIV-infected cats is to optimise basic husbandry and to treat any concurrent conditions early in the disease course. Currently, no available drugs are registered for the treatment of FIV infection. Critically, the euthanasia of healthy FIV-infected cats, and sick FIV-infected cats without appropriate clinical investigations, should not occur
