Awareness of eco-labeling of students of higher education in Hong Kong

Lam, Tsz-him, 林子謙 January 2014 (has links)
Eco-labels inform consumers about the environmental aspects of a product or a service. Consumers who are concerned with environmental issues can use the information on eco-labels to learn the environmental aspects of the products that they buy. The aim of this study is to determine how often the students of higher education pay attention to eco-labels when they are purchasing and the levels of the five internal factors that may motivate the consumers to pay attention to eco-labels. These factors are pro-environmental attitude (willingness to pay higher prices for products with eco-label), perceived consumer effectiveness (how much they believe that individual actions can improve the environment), belief in environment-friendly buying, trust in eco-label and knowledge in eco-labels. This study provided an opportunity to learn if the students consider the environmental aspects when they are buying and what teachers and education professionals can do to encourage the students to pay attention to eco-labels. Three textbooks used for General Studies for Primary students, three textbooks used in Integrated Science for Secondary 1-3 students and six teaching materials published by publishers (there is no textbook for Liberal Studies that is standardized by Education Bureau) used in Science, Technology and the Environment in Liberal Studies for Secondary 4-6 students were reviewed to find if the topic of eco-labeling was mentioned in them. It was found that none of the textbooks used for General Studies for Primary students mentioned eco-labeling, all textbooks used in Integrated Science used for Secondary 1-3 mentioned the Energy Efficiency Label and all teaching material used in liberal studies also mentioned Energy Efficiency Label, among them, one book mentioned the European Union’s Eco-label. A survey was carried out to assess how often students pay attention to eco-labels and how much they agree to statements relating to the five internal factors that may motivate them to pay attention to eco-labels. A test was given to assess their knowledge in the Energy Efficiency Label Scheme (EELS) issued by the Electrical and Mechanical Service Department and eco-labels issued to food and wood products respectively. The mean was 2.8(on a scale of 6, in which 1 means strongly disagree and 6 means strongly agree), when asked if they agreed that they often pay attention to eco- label when they were buying 3.5 for pro-environmental attitude, 4.2 for perceived consumer effectiveness, 3.4 for belief in environmental buying, 3.6 for trust in eco-labels and 3.6 in perceived knowledge in eco-labels. 63.2% of the students correctly answered that there are five grades in EELS, 40% of students correctly chose that the lower the grading, the more efficient is the electrical appliance. 8.4% of students correctly chose all five kind of electrical applicants that are mandated to show EEL. 2.1% attempted to name any eco-labels issued to wood products and 3.1% attempted to name any eco-labels issued to food products. It was concluded that students do not often pay attention to eco-labels when they are buying and that the limited knowledge in eco-labels was the potential cause. / published_or_final_version / Environmental Management / Master / Master of Science in Environmental Management

An Optimization Model for Eco-Driving at Signalized Intersection

Chen, Zhi 16 December 2013 (has links)
This research develops an optimization model for eco-driving at signalized intersection. In urban areas, signalized intersections are the “hot spots” of air emissions and have significant negative environmental and health impacts. Eco-driving is a strategy which aims to reduce exclusive fuel consumption and emissions by modifying or optimizing drivers’ behaviors. With the help of vehicle-to-vehicle (V2V) communication and vehicle-to-infrastructure communication (V2I), eco-driving could utilize the signal phase and the queue-discharging time information to optimize the speed trajectories for the vehicles approaching an intersection in order to reduce fuel consumption and emissions. A few research studies have been conducted on the development of algorithms that utilize traffic signal information to reduce fuel consumption and emissions. Hence, the goal of this research is to develop an optimization model to determine the optimal eco-driving trajectory (the speed profile) at a signalized intersection, which aims to achieve the minimization of a linear combination of emissions and travel time. Then enumeration method, simplex optimization and genetic algorithm are investigated to determine a practicable and efficient method to solve the proposed optimization problem. As various scenarios of distance from the vehicle to the intersection, queue discharging time and weights of emission/travel time will lead to different optimal trajectories and different emissions and travel times. A sensitivity study is conducted to analyze and compare the performance of the optimal solution in various scenarios of different such parameters. In addition, a baseline study is conducted to investigate the benefits of eco-driving when drivers only decelerate in advance but not apply the recommended speed trajectory. The results of case study show that genetic algorithm is a preferred method to solve the proposed optimization problem; Eco-driving could achieve satisfied reduction in emissions without significantly increasing travel time and emissions is more sensitive to various scenarios than travel time; Eco-driving still could achieve reduction in emissions as long as the drivers decelerate earlier even though the they would not apply the recommended speed trajectory under certain conditions.

A dengue por ser uma enfermidade recorrente com manifestações em formas graves e letais, tem se destacado entre as demais como alvo de preocupação no panorama de saúde pública brasileiro. Desse modo, a pesquisa buscou estudar os fatores associados à ocorrência da dengue, propondo um modelo eco-sociossanitário, a partir da cidade de Riacho de Santana-BA, com vistas a delimitar um modelo explicativo da enfermidade. A pesquisa de delineamento ecológico fez uso de dados secundários referentes às notificações de dengue, índices de infestação larvária por Aedes aegypti, condições socioeconômicas, sanitárias e climáticas da área de estudo, tratados com ferramentas estatísticas e análise espaço-temporal. Os resultados indicaram que o perfil sociodemográfico das pessoas acometidas por dengue em Riacho de Santana é similar ao da população: sexo feminino, faixa etária de 20-49 anos, correspondendo a faixa economicamente ativa, a cor da pele branca e parda e pessoas com ensino médio completo e cursando entre a 1ª e 4ª série. Assim, como a infestação larvária do Aedes aegypti, a dengue acompanhou a sazonalidade da umidade e precipitação, sendo que os valores mais elevados foram registrados no período chuvoso. A partir da análise espacial pôde-se observar que houve uma tendência de manutenção das notificações nas proximidades do bairro Peral, o qual compartilha de setores censitários com população de renda média baixa, infestação predial média no período chuvoso, taxa de ocupação domiciliar e densidade demográfica elevadas. Os indicadores de saneamento básico não apresentaram variações significativas entre os setores censitários, como resultado não se obteve correlação linear estatisticamente significante entre estes indicadores e a infestação larvária do vetor, como era esperado. Assim, os resultados obtidos nas análises quantitativa e qualitativa sugerem que os criadouros existentes sejam “cultivados” nos domínios público e privado. Nota-se que a incidência de dengue em Riacho de Santana, como em outros municípios brasileiros e no bairro Peral é resultado de um processo de determinação social. O modelo eco-sociossanitário proposto, pautado na promoção da saúde, ressalta a necessidade de interação dos atores sociais e Estado na formulação de políticas públicas que atendam as demandas territoriais e possam intervir sobre os determinantes de ordem social, ambiental e cultural existentes na reprodução de dengue
