Environmental Ethics, Survival And Apocalypse: An Analysis Of Margaret Atwood’S Maddaddam Trilogy, Sarawut Kururatphan Jan 2021

Environmental Ethics, Survival And Apocalypse: An Analysis Of Margaret Atwood’S Maddaddam Trilogy, Sarawut Kururatphan

Chulalongkorn University Theses and Dissertations (Chula ETD)

This thesis examines the connection of ethics and survival in the pre- and post-apocalyptic worlds in Margaret Atwood's MaddAddam trilogy: Oryx and Crake (2003), The Year of the Flood (2009), and MaddAddam (2013). It investigates the author’s imaginings of a dystopian society marked by rampant technocratic capitalism and unchecked scientism in Oryx and Crake. Applying Murray Bookchin's social ecology to shed light on the root causes of the apocalypse, it argues that hierarchical ideology and diversiform inequality deeply rooted in society lead to warped ethics, affecting the crisis. This thesis also examines environmental ethics which is embedded in the belief …

Effects Of Working Memory On Structural Competition In Processing English Present Tense Morphology By L1 Thai Learners, Sonthaya Rattanasak Jan 2021

Effects Of Working Memory On Structural Competition In Processing English Present Tense Morphology By L1 Thai Learners, Sonthaya Rattanasak

Chulalongkorn University Theses and Dissertations (Chula ETD)

In the course of second language (L2) acquisition, L2 grammatical processing is often found to be dissimilar to that of native speakers, and nonnative processing difficulties have been attributed to various sources. In the realms of agreement processing, whether both first language (L1) and L2 linguistic systems are co-activated simultaneously within a bilingual mind during grammatical processing remains an active question in language sciences. This study examined individual differences in terms of working memory capacity and distance-based complexity in L2 agreement processing. In two word-by-word self-paced reading experiments, a total of 80 agreement-lacking Thai learners of L2 English and 80 …

Investigating Sustainable Consumption Practices: A Case Of Single-Use Plastics In Online Food Delivery Market, Thailand, Boonchanit Wongprapinkul

Chulalongkorn University Theses and Dissertations (Chula ETD)

Online food delivery platforms have demonstrated their financial success in the Thai market during the past few years. As a result, 560 - 2,856 million pieces of Single-use Plastics (SUPs) are expected each year. Furthermore, the Coronavirus Disease 2019 (COVID-19) caused a dilemma in sustainable consumption and intensified the plastic waste situation. The social dilemma poses difficult short-term choices between health and the environment. The concern is that while Thais have started to adopt new sustainable lifestyles with the no-plastic-bag policy, environmentalists worry that this COVID disruption will have a long-term behavioural impact on SUPs consumption habits.

Developing Tanjung Kelayang As A New Bali: An Analysis Of Sustainable Tourism Policy And Implementation, Herdi Andrariladchi

Chulalongkorn University Theses and Dissertations (Chula ETD)

Indonesia has seen the success of Bali as the most prominent tourism destination in the country. Therefore, the initiative to deploy the benefits of tourism development throughout several regions of Indonesia is known as the “10 New Bali’s”. Nevertheless, it is still questionable whether Bali is an example of sustainable tourism or not. In developing the “10 New Bali’s”, the Indonesian government is aiming at increasing the number of tourists rather than at achieving the goal of sustainable tourism destination development. One of the destinations designated under this initiative is Tanjung Kelayang in Belitung Island, and therefore it is selected …

Effects Of Configuration And Operating Conditions On Turbidity Removal Of Jet Clarifier, Ploypailin Romphophak Jan 2021

Effects Of Configuration And Operating Conditions On Turbidity Removal Of Jet Clarifier, Ploypailin Romphophak

Chulalongkorn University Theses and Dissertations (Chula ETD)

In water treatment, flocculation creates large and weighty flocs enough to be removed by the downstream processes of sedimentation and filtration. Among the various existing technologies, the jet clarifier is considered as an effective and compact system as it couples flocculation and clarification in a single unit. For the design of jet mixing, much experimental work has been done and many correlations have been proposed. However, these correlations are case specifics, and, to date, there is no comprehensive view for the flocculation aspect. In order to evaluate the performance of the jet clarifier for turbidity removal and understand hydrodynamics to …

Do Issuers Affect Derivative Warrants Overpricing? Evidence Of Thailand, Sarunporn Thupthong Jan 2021

Do Issuers Affect Derivative Warrants Overpricing? Evidence Of Thailand, Sarunporn Thupthong

Chulalongkorn University Theses and Dissertations (Chula ETD)

Derivative warrants have become increasingly popular in many countries. However, numerous literatures provide the empirical evidences that derivative warrants are overpriced relative to the comparable options. Many researchers found that the derivative warrant overpricing can be explained by hedging cost, liquidity premium, market power, and asymmetric information of investors. These explanations are likely to be related to characteristics of derivative warrant issuer. Therefore, this paper comes up with the objective to reconfirm the overpricing phenomenon in Thailand and investigate the issuer identity effect on the derivative warrant overpricing as well as examine what issuer’s characteristics cause the level of overpricing …
