Conflicts occur when people (or other parties) perceive that‚ as a consequence of a disagreement‚ there is a threat to their needs‚ interests or concerns. Although conflict is a normal part of organization life‚ providing numerous opportunities for growth through improved understanding and insight‚ there is a tendency to view conflict as a negative experience caused by abnormally difficult circumstances. Disputants tend to perceive limited options and finite resources available in seeking solutions

High School Students’ Conceptions about Energy in Chemical Reactions (focusing only in exothermic and endothermic reactions). Aim The aim of this study is to investigate students’ understanding of the energy concept in chemical reactions particularly in endothermic-exothermic reactions. Both qualitative and quantitative methodology was used for this investigation. A twenty-item multiple choice test was developed about the topic to measure the students’ understandings. This concept test was

Abstract “Reaction Time” is the interval of time between the application of a stimulus and the detection of a response and has been thought to differ based upon the effects of modality and warning signals. In the “Reaction Time” experiment a total of 24 students from the University of Cincinnati participated in an experiment consisting of two sensory modalities‚ audition and vision‚ which were combined with two levels of warning signal status. The two levels of warning signal status were signal

The Wittig reaction is a unique reaction that can be carried out in various ways as our prompt exemplifies. We will be primary focusing on the second of the three schemes. In The usual formation of an ylide occurs via Sn2 attack of a PR3 group on an alkyl halide‚ which is then followed by a strong base deprotonating of one of the hydrogens on the methyl which the PR3 attacked. Before we dive into the details of the reaction occurring in scheme 2 it will be important to understand the mechanism which
