Description
The handling of waste encompasses the following processes: recycling, collection, treatment, and disposal. It is crucial to provide a cost-effective waste management system that improves public health and reduces environmental risks. In developing countries, proper handling of solid and hazardous wastes remain severely limited in urban cities if the industries and hospitals producing it do not take responsibility. Recycling and reusing of 12% of total waste in Phnom Penh is an active industry in Cambodia, driven by an informal network of waste pickers, collectors, and buyers. This thesis examines the environmental situation of solid and hazardous wastes in Phnom Penh. The socio-economic background of waste pickers and their current practices for handling solid and hazardous wastes will be mainly discussed in order to understand health and sanitation impacts and risks for disposal of solid and hazardous waste by these informal waste pickers. Surveys and interviews with the following sources are conducted: waste pickers, community members, observation at local dumpsites, governmental officials, and other non-government organization agencies in Phnom Penh, Cambodia. This thesis reports the external and internal factors that hinder safety and cost-effective management for disposal of solid and hazardous wastes. Multiple literature reviews are assessed in regards to the health effects, economic, and social impacts in developing countries. Evidentially, after attending several training and environmental awareness-raising programs, waste pickers expressed concerns about their health and the environment. Instead of receiving support, waste pickers are under economic pressure to use improper tools for waste picking, to stop working, get access to health care/service, to change their career, and prevent contact to limit serious communicable diseases and disability. As a result, the government and other related government agencies have made an effort to establish sanitation handling, treatment, and disposal systems by closing the old dumpsite. Due to limited entrepreneurship and business experience after training, most waste pickers cannot initiate micro business or find new jobs and then resume their waste picking. In conclusion, this thesis proposed that there are alternative technologies and management methods that will allow waste pickers to maintain employment while minimizing hazardous waste. Some examples of alternatives for waste pickers are establishing a material recovery center and alternative higher income occupation.

Description
Gloria is a work written for SATB choir and brass quintet that uses the traditional Latin text of the Gloria found in the ordinary of the Mass. The piece is approximately fourteen minutes and explores a variety of textures, colors, and timbres of the brass quintet and choir. The composition uses quartal sonorities mixed with upper tertian structures while avoiding simple triads and stable root position voicings until the most important climactic moments. The Gloria opens with a fanfare presenting the initial rhythmic motive in a call and response between the brass and choir before the irregular meters of the A section enter. The piece develops a variety of sonorities, pitch collections, and timbres before arriving at the first climactic moment on the text "Rex" (King). The music slowly comes to a point of repose with a brass interlude revealing the motives used in the B section. The choir begins the B section a cappella on the text "Dómine Fili unigénite, Jésu Chríste" (Lord Jesus Christ, the only begotten Son). The section features a dialogue between the brass and choir, though the two groups never sound together. The section includes a lyrical soprano duet incorporating dissonant intervals preceding the choir's response on the text requesting the mercy of the Lord. The section comes to a somber, penitential rest ending with the brass quintet response. The piece gradually builds and accelerates to the second climactic moment on the word "Jésu." From there it once again gains momentum toward the return of the A section on the text "Cum Sáncto Spíritu" (With the Holy Spirit). After a climactic "Amen" section, the composition concludes with a return to the material found in the introduction followed by an affirming brass postlude.
