There is a globally acknowledged urgency for mankind to transition toward sustainability. Empowering people to make sound assessments is the basis for desirable transitions. ‘Education for sustainable development’ (ESD) is an interdisciplinary learning process advancing knowledge, understanding and action for sustainability. To encourage sustainability transitions ESD needs to be personal and place-specific. One platform provisioning for such learning is ‘ecotourism’, where participants have a heightened sense of self, others and the environment. Hence a practice incorporating ESD into ecotourism is investigated in this thesis, to determine whether the setting would be propitious for fostering sustainability transitions. The pertinent sustainability concepts are assessed, and ‘social practice theory’ is utilized in a case study. The approach of social practice theory was preferable, as it holds the assumption that people are able to act in relation to collective cultural activities rather than in immediate responses to internal or environmental events. The effect of ESD in ecotourism is analyzed through observations and unstructured interviews conducted in a case-study in Turkey – Narköy, which is a hotel, organic farm and educational facility. The findings imply that through social practice, pro-environmental transitions can be encouraged and strengthened, with the provisions of having freedom for learning, social interaction, connection with nature, tangible activities and inclusive approach.

In this thesis, a system to locate an electrostatic discharge (ESD) event within an electronic device has been developed. ESD can cause a device to fail legally required radiated emissions limits as well as disrupt intended operation. The system used a fast oscilloscope with four channels, each channel attached to a high frequency near-field antenna. These antennas were placed at known locations in three dimensional space to measure the fields radiated from the ESD event. A Time-Difference-of-Arrival technique was used to calculate the location of the ESD event. Quick determination of the ESD event location provides developers with a tool that saves them time and money by eliminating the time-consuming and tedious method of general ESD mitigation within a product.

In today’s world, concern has been raised about that the existing means of development are unsustainable. As a solution Education for Sustainable Development (ESD) has been engaged around the world as a step to build a more sustainable society. Throughout the United Nations Decade of Education for Sustainable Development (DESD), Japan has promoted ESD through addressing it in the national educational law and plans as well as emphasizing it in course of study. As the DESD reached its end, this study aims to shed light on how ESD, an international framework, is understood and implemented on a micro level. Through a qualitative case study focused on the selected elementary and junior high schools in Kesennuma City, Miyagi, Japan, the findings show that local unique characteristics such as environmental and social factors influence the implementation of ESD. Furthermore, the findings also illustrate that learning of ESD takes place at various locations beyond the classrooms where the participants get involved in the local community that provides various professional knowledge and skills. Through the learning of ESD, which emphasizes experience and interaction with the learning partners, the aim is to foster the students’ abilities to think critically, identify a problem independently and take actions as well as to cooperate with others. At the same time, the study also shows that a holistic understanding of ESD from the teachers’ is needed in order to integrate ESD into the entire education.

Ces travaux s'inscrivent dans un contexte où les contraintes vis-à-vis des décharges électrostatiques sont de plus en plus fortes, les circuits de protection sont un problème récurrent pour les circuits fonctionnant à hautes fréquences. La capacité parasite des composants de protection limite fortement la transmission du signal et peut perturber fortement le fonctionnement normal d'un circuit. Les travaux présentés dans ce mémoire font suite à une volonté de fournir aux concepteurs de circuits fonctionnant aux fréquences millimétriques un circuit de protection robuste présentant de faibles pertes en transmission, avec des dimensions très petites et fonctionnant sur une très large bande de fréquences, allant du courant continu à 100 GHz. Pour cela, une étude approfondie des lignes de transmission et des composants de protection a été réalisée à l'aide de simulations électromagnétiques et de circuits. Placés et fragmentées le long de ces lignes de transmission, les composants de protection ont été optimisés afin de perturber le moins possible la transmission du signal, tout en gardant une forte robustesse face aux décharges électrostatiques. Cette stratégie de protection a été réalisée et validée en technologies CMOS avancées par des mesures fréquentielles, électriques et de courant de fuite.

This dissertation reports a study exploring adult engagement with sustainability learning practices in EcoSchools-certified secondary schools in Canada, Lithuania and Sweden as a means towards shaping a liveable future. The study is situated in the area of education for sustainable development. The study design was initially based on an interest in revealing specific practices of sustainability education as a means of improving the relationship between environmental impact and wealth. While echoing findings in the existing literature, this research contributes to the development of the field through insight into the perspectives that adults bring to sustainability education. Primary data collected in the spring of 2006 were recorded (mostly single) semistructured interviews with 30 individuals (national coordinators, caretakers, teachers and administrators), including 10 Canadians from four schools, 14 Lithuanians from four schools, and six Swedes from two schools. Four phases of qualitative analysis were used on the data: initial transcript coding and trends; précis document trends; a six-stage model of interview responses allowing vertical (between question) and horizontal (between stage) comparisons; word maps of subthemes as a scaffold to detail participants’ four primary views (long, wide, deep, dynamic) regarding sustainability. Ultimately, the results of this study point less than expected to revealing specific transferable practices regarding success and challenge in EcoSchools. Rather, these findings provide some insight into a means of shaping a sustainable future through an individual’s sustainability perspective: a living responsiveness based on a sense of connection, supported by improved sustainability cognition, and realized through sustainability practice and considered engagement.

In modern integrated circuits, electrostatic discharge (ESD) is a major problem that influences the reliability of operation, yield and cost of fabrication. ESD discharge events can generate static voltages beyond a few kilo volts. If these voltages are dissipated in the chip, high electric field and high current are generated and will destroy the gate oxide material or melt the metal interconnects. In order to protect the chip from these unexpected ESD events, special protection devices are designed and connect to each pin of the IC for this purpose. With the scaling of nano-metric processing technologies, the ESD design window has become more critical. That leaves little room for designers to maneuver. A good ESD protection device must have superior current sinking ability and also does not affect the normal operation of the IC. The two main categories of ESD devices are snapback and non-snapback ones. Non-snapback designs usually consist of forward biased diode strings with properties, such as low heat and power, high current carrying ability. Snapback devices use MOSFET and silicon controlled rectifier (SCR). They exploit avalanche breakdown to conduct current. In order to investigate the properties of various devices, they need to be modeled in device simulators. That process begins with realizing a technology specific NMOS and PMOS in the device simulators. The MOSFET process parameters are exported to build ESD structures. Then, by inserting ESD devices into different simulation test-benches, such as human-body model or charged-device model, their performance is evaluated through a series of figures of merit, which include peak current, voltage overshoot, capacitance, latch-up immunity and current dissipation time. A successful design can sink a large amount of current within an extremely short duration, while it should demonstrate a low voltage overshoot and capacitance. In this research work, an inter-weaving diode and SCR hybrid device demonstrated its effectiveness against tight ESD test standards is shown.

Syftet med den här studien var att ta reda på vad verksamma lågstadielärare läser in i begreppet hållbar utveckling och hur de tänker sig kunna tillämpa detta i verksamheten, och slutligen vilja skillnader och likheter som går att finna mellan deras uttalanden. Tre verksamma lärare intervjuades och detta sattes sedan i relation till litteratur om hållbar utveckling i skolan. Ett av studiens resultat var att lärarna talade om den ekologiska dimensionen av hållbar utveckling först och främst för att sedan lite längre in i samtalet, också föra in den ekonomiska och sociala dimensionen. Detta resultat bekräftas av övrig forskning på området. Den sociala dimensionen av hållbar utveckling var den dimension som lärarna pratade minst om under intervjuerna, trots att den enligt forskare kan anses vara målet för arbetet med hållbar utveckling. De tre intervjuade lärarna i den här studien talade alla tre mer eller mindre om alla tre dimensionerna som brukar läggas in i begreppet hållbar utveckling, vilket kan ses som att även om de kommer upp olika fort under intervjuens gång, så finns de ändå med när lärarna pratar om undervisningen alla tre. / <p>SO</p>
