Urban Heat Island (UHI) has significant impacts on the buildings energy consumption and outdoor air quality (OAQ). Various approaches, including observation and simulation techniques, have been proposed to understand the causes of UHI formation and to find the corresponding mitigation strategies. However, the causes of UHI are not the same in different climates or city features. Thus, general conclusion cannot be made based on limited monitoring data.
With recent progress in computational tools, simulation methods have been used to study UHI. These approaches, however, are also not able to cover all the phenomena that simultaneously contribute to the formation of UHI. The shortcomings are mostly attributed to the weakness of the theories and computational cost.
This paper presents a review of the techniques used to study UHI. The abilities and limitations of each approach for the investigation of UHI mitigation and prediction are discussed. Treatment of important parameters including latent, sensible, storage, and anthropogenic heat in addition to treatment of radiation, effect of trees and pond, and boundary condition to simulate UHI is also presented. Finally, this paper discusses the application of integration approach as a future opportunity.
Rapid urbanization of the planet is occurring at an unprecedented pace, primarily in arid and semi-arid hot climates [Golden, J.S., 2004. The built environment induced urban heat island effect in rapidly urbanizing arid regions – a sustainable urban engineering complexity. Environ. Sci. J. Integr. Environ. Res. 1 (4), 321–349]. This growth has manifested itself as a cause of various impacts including elevated urban temperatures in comparison to rural sites known as the Urban Heat Island (UHI) effect [Oke, T.R., 1982. The energetic basis of the urban heat island. Q. J. R. Meteor. Soc. 108, 1–24]. Related are the increased demands for electric power as a result of population growth and increased need for mechanical cooling due to the UHI. In the United States, the Environmental Protection Agency has developed a three-prong approach of (1) cool pavements, (2) urban forestry and (3) cool roofs to mitigate the UHI. Researchers undertook an examination of micro scale benefits of the utilization of photovoltaic panels to reduce the thermal impacts to surface temperatures of pavements in comparison to urban forestry. The results of the research indicate that photovoltaic panels provide a greater thermal reduction benefit during the diurnal cycle in comparison to urban forestry while also providing the additional benefits of supporting peak energy demand, conserving water resources and utilizing a renewable energy source.
Because of a projected surge of several billion urban inhabitants by mid-century, a rising urgency exists to advance local and strategically deployed measures intended to ameliorate negative consequences on urban climate (e.g., heat stress, poor air quality, energy/water availability). Here we highlight the importance of incorporating scale-dependent built environment induced solutions within the broader umbrella of urban sustainability outcomes, thereby accounting for fundamental physical principles. Contemporary and future design of settlements demands cooperative participation between planners, architects, and relevant stakeholders, with the urban and global climate community, which recognizes the complexity of the physical systems involved and is ideally fit to quantitatively examine the viability of proposed solutions. Such participatory efforts can aid the development of locally sensible approaches by integrating across the socioeconomic and climatic continuum, therefore providing opportunities facilitating comprehensive solutions that maximize benefits and limit unintended consequences.
Background: The consequences of poor communication or non-therapeutic communication cannot be overemphasized; these can include non-adherence to treatment plan, reduced treatment compliance, higher psychological morbidity, dissatisfaction with care and poor patient-caregiver relationship. Patients’ perception of how they are being treated affects how they respond to treatment plans and medication regimens
Method: The project consisted of providing education on the principles of therapeutic communication to healthcare workers in an outpatient psychiatric clinic. Follow up materials on therapeutic communication principles were provided on a weekly basis for one month. A pre-survey questionnaire was given to patients before intervention and a post-survey questionnaire after intervention to determine patient satisfaction with care and degree of communication with healthcare workers. The Short Assessment of Patient Satisfaction (SAPS) and the Communication Assessment Tool-Team (CAT-T) were the instruments utilized in this project.
Finding: Patient satisfaction and communication with staff were statistically and significantly improved after education on therapeutic communication was given to staff.
Conclusion: Education on therapeutic communication is an effective intervention tool in improving patient’s satisfaction and communication with staff and health care team members in a psychiatric outpatient clinic.
Method: Pre-licensure nursing students participated in a high fidelity simulation experience. One group of students viewed a video role modeling SBAR before beginning the simulation (N=20). Student communication using SBAR was evaluated after the simulation experience for both groups. The second group of students did not view the video role modeling SBAR until after completing the simulation (N=20).
Results: Viewing a role modeling video on SBAR before participating in a simulation had no effect on the students SBAR performance after the simulation. The students’ evaluation of the video reported the video provided a clear, helpful demonstration of the SBAR communication method.
Conclusion: Role modeling can be used to improve students’ ability to apply SBAR, however more research needs to be done to determine the most effective way to role model the behavior.
