Proceedings of the National Conference on Water, Food Security and Climate Change in Sri Lanka, BMICH, Colombo, Sri Lanka, 9-11 June 2009. Vol. 2. Water quality, environment and climate change

This is the second volume of the proceedings of the National Conference on ‘Water for Food and Environment’, which was held from June 9 –11, 2009 at the Bandaranaike Memorial International Conference Hall (BMICH). The volumes 1 and 3 have been produced as separate documents of this report series. In response to a call for abstracts, 81 abstracts were received from government institutes dealing with water resources and agriculture development, universities, other freelance researchers and researchers from the International Water Management Institute (IWMI). Forty seven of the eighty-one abstracts that were submitted were accepted for compiling full papers. In the past couple of years the sharp increase in food prices worldwide has raised serious concerns about food security, especially in developing countries. To effectively address these concerns a holistic approach is required that encompasses improved agricultural water productivity, adaptation to climate change, targeted and appropriate institutional and financial measures, and a consideration of environmental issues. The main purpose of the conference was to share experiences in these areas and to find opportunities to improve farmers’ incomes and food production, and to promote environmentally sustainable practices in Sri Lanka in the face of growing water scarcity and the challenges of climate change.Wetlands, / Environmental flows / Assessment / Water allocation / Case studies / Rivers / Farming systems / Models / Groundwater / Aquifers / Domestic water / Rainfed farming / Climate change / Wastewater irrigation / Rice

Elementary College and Career Readiness Curriculum: A School Counselor Intervention

Labor market projections indicate that across all industries, jobs will require increased post-secondary education, credentials, and training requirements. The U.S. will not have the workers that meet these requirements, resulting in a worker shortage. Knowing this predicted shift, our current education system is charged with the responsibility of educating and preparing students for these positions and to fill the needs of our society. Career development is a lifelong process beginning in childhood, and school counselors are responsible for supporting this healthy development. Despite this call to action, there is a of lack content, resources, or evidence-based programs available for elementary career counseling interventions. This project explores and combines the developmental needs of elementary students and effective implementation strategies for healthy career growth to create a ready-to-use fourth grade Tier One intervention for school counselors. All necessary resources are included for lesson plans, career day facilitation, and parent/guardian involvement. Data collection procedures within the unit will facilitate the creation of evidence for school counselors and researchers to more effectively advance the elementary career development field, advocate for elementary school counseling, and implement evidence-based career counseling interventions

The Distinctive Regulatory Mechanisms of Bacterial Acetyl-CoA Carboxylase

Metabolic Regulation is a complex system used to control cellular metabolism in response to conditions in the cell’s environment. For most enzymes, the cell can rely upon a minimal amount of regulation; however, critical enzymes, such as acetyl-CoA carboxylase, must be regulated at multiple levels. Acetyl-CoA carboxylase catalyzes the first committed step in fatty acid synthesis. In bacteria, acetyl-CoA carboxylase forms a complex of three subunits–biotin carboxylase, biotin carboxyl carrier protein, and carboxyltransferase–which catalyze the carboxylation of acetyl-CoA to form malonyl-CoA via two half-reactions. In the first half-reaction, biotin covalently linked to biotin carboxyl carrier protein is carboxylated by biotin carboxylase. Carboxyltransferase catalyzes the second half-reaction where the carboxyl group is transferred from carboxybiotin to acetyl-CoA, forming malonyl-CoA. As acetyl-CoA carboxylase is a critical enzyme in cell growth, it is subject to multiple forms of regulation. This dissertation describes two distinct mechanisms of regulation of acetyl-CoA carboxylase. Previous reports showed that the downstream product of fatty acid synthesis, palmitoyl-acyl carrier protein, inhibits catalysis by acetyl-CoA carboxylase via negative feedback regulation. This dissertation reports the acetyl-CoA carboxylase complex was found to exhibit a pronounced hysteresis when inhibited by palmitoyl-acyl carrier protein. Alternatively, palmitoyl-acyl carrier protein does not inhibit either half–reaction. Structure-function studies of palmitoyl-acyl carrier protein demonstrate the inhibitory moiety is the cofactor pantothenic acid. This dissertation also reports that the biotin carboxyl carrier protein subunit of acetyl-CoA carboxylase regulates catalysis. The biotin carboxyl carrier protein in E. coli is composed of two domains: the N-terminal domain, and the C-terminal domain. The C-terminal domain contains the biotin cofactor, and acts as a substrate, while the function of the N-terminal domain was unknown. In vivopull-down assays demonstrated the N-terminal domain is not required for formation of the catalytic complex, whereasin vitroanalyses demonstrated that the N-terminal domain binds biotin. Thus, it is likely the role of the N-terminal domain of biotin carboxyl carrier protein in bacterial acetyl-CoA carboxylase is to bind and stabilize the carboxybiotin intermediate during catalysis

Evaluation of patient perception towards dynamic health data sharing using blockchain based digital consent with the Dovetail digital consent application : a cross sectional exploratory study

Background New patient-centric integrated care models are enabled by the capability to exchange the patient’s data amongst stakeholders, who each specialise in different aspects of the patient’s care. This requires a robust, trusted and flexible mechanism for patients to offer consent to share their data. Furthermore, new IT technologies make it easier to give patients more control over their data, including the right to revoke consent. These characteristics challenge the traditional paper-based, single-organisation-led consent process. The Dovetail digital consent application uses a mobile application and blockchain based infrastructure to offer this capability, as part of a pilot allowing patients to have their data shared amongst digital tools, empowering patients to manage their condition within an integrated care setting. Objective To evaluate patient perceptions towards existing consent processes, and the Dovetail blockchain based digital consent application as a means to manage data sharing in the context of diabetes care. Method Patients with diabetes at a General Practitioner practice were recruited. Data were collected using focus groups and questionnaires. Thematic analysis of the focus group transcripts and descriptive statistics of the questionnaires was performed. Results There was a lack of understanding of existing consent processes in place, and many patients did not have any recollection of having previously given consent. The digital consent application received favourable feedback, with patients recognising the value of the capability offered by the application. Patients overwhelmingly favoured the digital consent application over existing practice. Conclusions Digital consent was received favourably, with patients recognising that it addresses the main limitations of the current process. Feedback on potential improvements was received. Future work includes confirmation of results in a broader demographic sample and across multiple conditions

Institutional arrangements for resource recovery and reuse in the wastewater sector

As populations grow and urban centres expand, meeting water demand and wastewater management requirements will become increasingly difficult. Goal 6 of the Sustainable Development Goals is to: ‘Ensure availability and sustainable management of water and sanitation for all’. Part of the approach to achieving this will be reusing wastewater and will require a greater understanding of the institutional arrangements that support or obstruct reuse. This research was designed to achieve this and aimed to develop a set of factors that investors could use to assess the institutional feasibility of reuse in a given setting. The methodology combined a case study approach, focusing on wastewater systems in Bangalore, India and Hanoi, Vietnam, with triangle analysis to assess: the content of policies and laws; the structures (formal and informal) to implement laws and reuse projects; and the culture around acceptance and engagement in reuse. The reuse practices observed in Bangalore were treatment and use within apartments, centralized treatment and sale to industries, use in agriculture after natural attenuation, groundwater recharge and lake regeneration. In Hanoi the only reuse was indirect use from rivers feeding fish ponds and fields, although formal treatment and use is planned. Critically, both cities have environmental and water resources policies and laws that advocate reuse, as well as related local legislation. However, support for reuse is not reciprocated in industrial, agricultural or fisheries law, the result being that reuse does not always take place as planned. Legislation is required along the whole sanitation chain to the point of wastewater use. Structures to implement reuse are also vital. In Bangalore the water board has initiated reuse projects and established the New Initiatives Division but resources are a limiting factor. Effective institutions include expertise, manpower and financing mechanisms, which are lacking in both cities. The environment agency is also engaged in reuse though legislation on recycling in residential and commercial complexes but guidance for users is inadequate, expectations are perceived to be excessive and monitoring is almost impossible. The driver for reuse is increasingly the benefits observed by users. In the case of apartments this is a reliable water source and reduced costs of water supply. As a result, a private sector in wastewater treatment is becoming established. The active civil society and strong, independent media are instrumental in providing information to potential users and holding authorities to account in Bangalore. Their absence in Hanoi is notable. In summary, institutional elements to be considered are: supportive legislation across all sectors; details of acceptable reuse, deterrents and inducements; budget allocation; structures to enable reuse; strong civil society, NGOs, courts, media and universities providing evidence of suitability and safety; donors and finance mechanisms; and stakeholders willing to use the products. Encumbrances are inconsistent or uncoordinated legislation, lack of cooperation and insufficient benefit sharing or perceptions of benefits along the reuse chain
