PRESERVICE TEACHERS’ THOUGHTS AND FEARS ABOUT DISCIPLINING CHILDREN

The purposes of this study were threefold: (1) to determine if fears and concerns about guiding children's behavior and misbehavior is a generalized feeling, or more related to specific circumstances and scenarios; (2) to determine which situations may give students the greatest and least amounts of anxiety; and (3) to explore the relationship between students’ beliefs about the causes of children's misbehavior and their anxiety about specific discipline situations.

After completing a questionnaire, preservice teachers in this study rated children's challenges to their authority as the most difficult. Discipline situations involving conflicts between children (e.g., refusing to share, not joining in activities) were rated as the least difficult to handle. Most of the preservice teachers believed children misbehaved because of a lack of social skills and developmental sophistication rather than because of bad parenting, inherent personality characteristics, or too many adult restrictions. Preservice teachers rated the difficulty of the discipline issues similarly regardless of their beliefs concerning the causes of misbehavior. Implications of this study are discussed.     

Influence of Process Parameters on Chlorinated Biocide Decontamination by li-CO2 on Artificially Contaminated Model Materials

ABSTRACT

Previously, heavy use of biocides for the treatment of objects made of organic materials in museum collections (e.g. ethnographic, historical collections) was very common. Now suitable decontamination methods/technologies are being sought. A decontamination treatment by li-CO₂ was optimized that considered the specific requirements of museum objects. The treatment was tested on model materials artificially contaminated with biocide solutions containing dichlorodiphenyltrichloroethane (DDT), pentachlorophenol (PCP), lindane, and permethrin or cypermethrin. High decontamination was achieved for DDT, lindane, PCP, and permethrin on artificially biocide loaded wool and wood model materials. Optimal process parameter settings for li-CO₂ decontamination include a single 30?min cycle for woolen materials and three sequential 30?min cycles each for wood. These methods allow a reduction of at least 90% of all biocides for wool and between 70% and 85% for wood. Decontamination of the latter was more effective for less polar biocides as DDT and permethrin. Despite a significant improvement in decontamination for wood using co-solvents such as acetone, ethanol, and methyl tertiary-butyl ether (MTBE), their use is not recommended due to the increased risk of damage to the objects, in particular if a surface coating is present.     

Exposure to Media Violence and Young Children with and Without Disabilities: Powerful Opportunities for Family-Professional Partnerships

There is growing concern regarding the amount and type of violence that young children are exposed to on a daily basis. Through media, popular toys and video games violent images are consistently present in children’s lives starting at a very young age. This paper discusses (a) the growing presence of young children’s exposure to media violence, (b) the influence of media violence on early childhood development and well-being, (c) the impact of media violence on young children with disabilities, and (d) recommendations for addressing this national dilemma within the context of family-professional partnerships.
