PTSD in Adolescents - Research Proposal Example Also, it useful in obtaining information regarding a phenomenon’s current status, in this case, PTSD in adolescents and possibility for the use of technology in research. The population for this research study will be adolescents aged between the ages of 13 and 19 who meet the DSM IV criteria for PTSD. In addition, the guardians or parents will have to provide written permission for the participation of the minors. The participants will be recruited via purposive sampling that will only consider a specific subset of the population (Bryman & Burgess, 2009), in this case, adolescents presenting with PTSD symptoms. Data will be collected from both primary and secondary sources. Secondary sources will include previous research studies and peer-reviewed articles, while primary data will be collected through interviews. The secondary data will provide information about the earlier use of technology in PTSD research, while the interviews will present information about perceptions and behavior of adolescents with PTSD. The interview will have a general inquiry plan with no specific set of questions or any particular order to avoid making the participants uncomfortable (Bryman & Burgess, 2009). The Structured Interview for PTSD has been utilized in numerous studies and assesses symptoms of PTSD, as well as behavioral guilt, survival, and risk factors (Bryman & Burgess, 2009). These are the issues, which the research study is seeking to address. It has 17 items that assign severity rating reflecting intensity and frequency. This method was chosen because it takes less time, around 20-30 minutes, which is important given the mental state of the participants. Other methods that could have been used include document review and observational methods.

Supply Chain Development - Essay Example The supply management handles all these activities in addition to coordination of all the partners in the supply chain channel. As the world advances and more goods and services are being demanded by the ever increasing population in the whole world, there is need to put up systems that are both efficient and effective to aid in this conversion of products and consequent supply to the final consumer. The construction supply chain is one of the local supply chains; it involves the design and construction of building structures. Numerous supply chains all around the world have been developed to cater for the needs of the consumers in that chain. The world is under a great threat due to effects of environmental degradation that has lead to numerous negative effects such as global warming, climatic change, deforestations and desertification, polar ice melting, loss in the scenic beauty of the landscape, increase of tropical and other diseases, creation of huge dumping sites that lead to air, water and land pollution affecting the human, plant and animal life in general. Due to this pollution the human population is under threat. There is need to diversify and intensify any or all activity geared to reversing these hazardous effects. According to Friedman (2008), there is need for greening supply chains. This has been brought about by increased media attention; additional regulation and research by the scientific society showing that human activity directly influence the climatic changes. These human activities are the core business in supply chains. Some of the ways of improving the supply chain include; Maximizing the utilization of materials and machines The material and machines form the core of every supply chain. Raw material are used virtually everywhere. In construction various raw material and machines are used to design and construct different structures to be used by various entrepreneurs running the supply chains. All waste must be reduced by improving the construction material utilization, there is great need to evaluate every material be used in the supply chain construction and evaluate its importance, its effects to the environment and the by product or the waste. For example if plastic bags are used to pack different construction materials e.g. cement, Then within a short periods the whole environment will be littered with plastic bags, proper material utilization not only lead to reduction of environmental degradation but also lead to increased profit margin by the construction company. Machine effectiveness The effectiveness of various machines to convert goods/raw materials to finished product also affects the supply chain. Effective machines lead to greater efficiency in conversion of goods to finished product. Different construction materials undergo transformation before be used in design and construction. Because these materials are used in large quantities, there is need to use machines that will reduce any wastes as the waste generated by these processes generally effect the environment in the long run. Technological advancement Embracing technological changes is another method of championing improvement in the supply
