title: International Climate Change Governance: Issues of Democracy, Institutions and the Media

authors: Pandey, Chandra Lal

subjects: climate change policy

abstract: The United Nations Framework Convention on Climate Change was established in 1992 to stabilize greenhouse gas concentrations in the atmosphere to prevent dangerous anthropogenic interference with the climate system. The nation states of the world have attempted to arrest climate change through a state-centric large scale multilateral treaty making process. Yet, over a period of more than twenty years, little has been achieved toward that objective. The making of international climate change governance required to arrest climate change is falling short. Greenhouse gases, which scientists consider to be the main culprit of climate change, are increasing rapidly making every subsequent year’s emissions concentration a new record. 
Climate scientists say global temperatures rising above 2 degrees Celsius could be extremely dangerous. The 1992 Convention, 1997 Kyoto Protocol, 2009 Copenhagen Accord and subsequent agreements have failed to translate the goal and achieve the threshold target as no serious and viable policies are forthcoming. Instead, the United Nations’ climate conferences have become a yearly chore for diplomats. 
The complexities of climate change governance arise not only from the nature and uncertainty of its impact, but also from its embedded relationships with social, cultural, political, economic, historical and institutional dimensions. Appropriate responses to address the challenges of climate change are difficult in the absence of potential solutions in sight. The pre-requisite for any effective policy responses is that the decision making process be democratic, transparent, and inclusive so that the ultimate addressees can ‘own’ the problem and contribute to solutions.
A sizable literature focuses on the causes and reasons behind climate change and advocates radical actions to arrest it. Other research highlights economic implications, alternatives to fossil fuels, consumption and production, scientific uncertainty and challenges the perennial North-South politics in seeking to explain the lack of progress. There has been little research on why international climate change governance is making only incremental progress.  This thesis takes as its starting point the paucity of attention to working out how and why progress has not been made, drawing on insights from climate change negotiations, major climate agreements and analyses of data on media communications on the issues of international climate change negotiations for policy making. 
The research recognizes the complexity of climate change and takes a comprehensive approach in considering why has there been little progress in the making of an effective international climate change governance to prevent climate change. The thesis takes three complementary approaches in addressing the central research question. The first develops from the concept of a democratic deficit and posits that the failure of progress can be attributed to a lack of the democratic processes in grappling with the issues. The second explores the state-centric framework of UNFCCC and posits that since the environmental issues are non-territorial, the challenges postulated by climate change cannot be resolved and progress made by solely relying on a state-centric approach. The third is to do with media communications and posits the role of the media in public education as central to develop the necessary public support for addressing the issues of climate change. The Kyoto Protocol and the Copenhagen Accord, and how they were achieved are central to this research as these are the two major climate change agreements achieved internationally so far. 
This research concludes that the approaches we have adopted so far have been inadequate because of the lack of involvement of the main stakeholders in decision making processes. The common but differentiated and historical responsibilities, pertinent principles in 1992, no longer reflect current economic growth and greenhouse gas emission patterns. There is a need to review our state-centric institutional framework toward a more inclusive, participatory, and deliberative accountability whereby the public and businesses can ‘own’ the problem. The role of the media is paramount in this because it is the media that passes information from the scientists, experts and policy makers to the public. The research concludes that the media has a key role to play and needs to be more critical in advancing measures to address the problems of climate change.

title: Enhancing consumer health question answering systems through rhetorical structure theory-guided large language model

authors: Liu, Chen

abstract: Consumer Health Question Answering (CHQA) systems have traditionally been designed around isolated capabilities—either factual medical correctness or empathetic support—rather than delivering integrated, multi-dimensional assistance. This separation fails to reflect the reality of consumer health consultations, where individuals typically express intertwined medical concerns, personal circumstances, and emotional distress within a single query. Existing CHQA architectures, often optimised for short, single-intent inputs, prioritise answer generation over question understanding and lack explicit mechanisms to jointly interpret informational and emotional support needs. Although Large Language Models (LLMs) have advanced the state of medical QA, most LLM-based systems still struggle to reconcile clinical reliability with context-sensitive empathy in complex consumer health questions.

To address this gap, this study adopts a Design Science Research (DSR) paradigm and introduces Joint Medical–Emotional Question Answering (JMEQA) as a new task that jointly understand and response medical informational needs and emotional support needs in Consumer Health Questions (CHQs). Grounded in Rhetorical Structure Theory (RST) and Appraisal Framework for Clinical Empathy (AFCE), the research proposes the Med-Emo CHQA architecture, a neural-symbolic unified, LLM-based system that augments answer generation with explicit question understanding. The architecture integrates hierarchical modules for question understanding and answer generation, unifying symbolic knowledge (an RST-based discourse structure tree that encodes intents, contexts, and rhetorical relations during the question-understanding stage) with neural network (LLM) via supervised fine-tuning and structured prompting.

To support system training and evaluation, this study constructs CHQA-MedEmo, the first large-scale, multi-layer corpus of Chinese health consultation records. The corpus is annotated for both medical informational needs and emotional support needs, with explicit contextual spans and discourse relations. System performance is assessed through controlled experiments and an expert reader study using a human-centred evaluation framework that jointly measures accuracy, personalisation, and empathy, alongside latency. Experimental and reader-study results show that the proposed architecture outperforms baseline and ablated models in full medical-need coverage and empathetic alignment, while maintaining lower latency.

Overall, this study advances the design of CHQA systems by demonstrating how symbolic, discourse-aware question understanding can be embedded into LLM workflows to produce responses that are simultaneously medically reliable, personally tailored, and emotionally supportive. The findings contribute design knowledge for Neural-Symbolic Integration (NSI), LLM-based CHQA in online health consultation settings and offer a scalable architectural paradigm for building complex, human-centred AI systems that balance informational rigour with affective care.

title: Biological flora of New Zealand 11. Eleochairs spacelata, kuta, paopao, bamboo spike sedge.

authors: Kapa, Mieke M

subjects: cultural

abstract: Information relevant to the ecology and morphology of Eleocharis sphacelata (Cyperaceae) available through published and unpublished sources is assembled and reviewed. Eleocharis sphacelata is a freshwater wetland sedge found growing at the edge of lake margins, swamps, lagoons, and bogs within New Zealand, Australia, and Papua New Guinea. It is a perennial rhizomatous herb, with tall green cylindrical culms rising from submerged rhizomes generally buried under water in aerobic soils. A tendency to dominate the deepwater margins makes E. sphacelata crucial to the ecology of this habitat as a source of food, shelter, and protection for invertebrates, birds, and fish. Eleocharis sphacelata is commonly named giant spike-rush, kuta, or paopao. Māori have traditionally used the plant for clothing and warm coverings within whare (houses). Recent interest comes from its use in restoration plantings and constructed wetlands.
