Seafloor characterization using airborne hyperspectral co-registration procedures independent from attitude and positioning sensors

The advance of remote-sensing technology and data-storage capabilities has progressed in the last decade to commercial multi-sensor data collection. There is a constant need to characterize, quantify and monitor the coastal areas for habitat research and coastal management. In this paper, we present work on seafloor characterization that uses hyperspectral imagery (HSI). The HSI data allows the operator to extend seafloor characterization from multibeam backscatter towards land and thus creates a seamless ocean-to-land characterization of the littoral zone

Water challenge and institutional response (a cross-country perspective)

This cross-country evaluation of institutional responses to problems in the water sector shows that changes in the nature of water problems have changed the development paradigm underlying water institutions. There is increasing recognition of how decentralized allocation mechanisms can influence economic forces and stakeholders in water sector decisions. As the notion of water provision as a public good and welfare activity gives way to the concept of water as an economic good and an input of economic activity, there is more policy concern about efficient and equitable use, cost recovery, and financial viability. All of the countries the authors studied (Australia, Brazil, Chile, China, India, Israel, Mexico, Morocco, South Africa, Spain, and Sri Lanka) are committed to changing the policies and institutions that have caused the present water sector crisis, but they are at different stages of institutional reform. Among cases discussed, Australia and Chile (and, in the United States, California and Colorado) are at an advanced (though not ideal) stage of institutional change. Israel, with its technologically advanced water sector, could well be ahead of them when the proposal to allow water transfers and decentralize water development and distribution systems takes practical shape. Tentative conclusions reached by the authors are: 1) Attempts to fix isolated parts of the water sector will influence other dimensions but an integrated approach is best. At the heart of such an approach should be institutional changes aimed at modernizing and strengthening legal, policy, and administrative arrangements for the whole sector. 2) Institutional changes taking place everywhere suggest that the opportunity costs of (and net gain from) institutional change is not uniform, suggesting that opportunity and transaction costs vary. 3) Funding agencies should focus efforts and resources in countries, areas, and subsectors that already have enough critical mass in institution-building to ensure success and lower transaction costs. 4) The sequence and pace of reform should reflect realities of scale economies and political pressures from reform constituencies. When possible, political economy should be exploited to move reform along more quickly.Environmental Economics&Policies,Water Conservation,Water and Industry,Water Supply and Systems,Decentralization,Water Supply and Sanitation Governance and Institutions,Town Water Supply and Sanitation,Water and Industry,Water Conservation,Water Use

Business Plan for Launching a Luxury Adventure Tour Operator Based in Canada

MOT Elite Travel Experiences (METE) is a tour operator and online travel agent start-up company based in Vancouver, British Columbia. METE is faced with the challenge of establishing itself as a business in the travel industry. However, recent advances in technology such as an increase in the number of broadband Internet users, search engine optimization, and the advent of smartphones have created an opportunity to capitalize on the growing popularity of online travel booking services. This trend towards online travel sales is stimulating new growth in the tourism industry and providing exciting opportunities for new entrants like METE. Analysis of current statistics and penetration rates for broadband internet and smartphone for countries travelling to Canada in the 25-44 year old age segment indicates that the United States, the United Kingdom (UK), Germany and France are the primary target markets for METE. Luxury travel has recovered from the recession of 2008-2009, and a growing, younger upper middle class and large proportion of High Net Worth Individuals (HNWI) in the under 45 year old segment in China are supporting a market for unique travel experience that METE plans to offer. The travel cycle introduces the inspiration, research, booking, experience, and sharing phases that comprise a framework to understand the relationship between travel and technology. METE plans to develop into competitive business as an on-line travel agent and tour operator that is able to deliver a comprehensive on-line and offline experience throughout the travel cycle

Electronic commerce logistics in developing countries: The case of online grocery shopping in Jordan

This thesis was submitted for the degree of Docter of Philosophy and awarded by Brunel University.Online grocery shopping is one of the Internet business applications that received much attention in the last few years. Online grocery shopping has grown at a fast scale in the developed countries, where customers and retailers have benefited from it. However, this service remains in its infancy stage in developing countries. Groceries are one of the most difficult objects to sell online mainly, because of sensory and delivery issues. Online customers still worry about product quality, and they demand optimum logistical services, convenience, reliability and timely delivery service. Therefore, retailers have to respond to these expectations by developing convenient logistical services while keeping this process cost-efficient as much as possible. The main aim of this research is to design an e-commerce logistical decision support system for grocery retailers in Jordan as a case study of applying online grocery shopping in a developing country. Grocery retailers will be exposed to this model, and will be able to determine the most suitable logistical delivery system in the future. In order to achieve this aim, the designed system incorporates a web ordering system to collect customer orders, embedded map source (Google Maps) and a database system. The collected data then exported to one of the available routing and scheduling online solutions in order to identify, analyze and statistically compare the cost efficiencies of the available delivery alternatives. Moreover, two specially designed questionnaires were distributed among a group of customers and grocery retailers in Jordan, asking about their attitudes towards online grocery shopping and its delivery service. The results from analyzing the questionnaires data statistically were also used as input parameters for the designed system evaluation process. The findings from the questionnaires data statistical analysis indicated that Jordanian customers and retailers have positive attitudes towards online grocery shopping. The results also showed that customers and retailers have serious concerns towards the delivery service in Jordan. Customers are mainly worried about the availability of a suitable delivery service, while retailers are worried about the market size for the delivery service. The findings from implementing and statistically testing the proposed model over three delivery alternatives showed that there are differences between the mean values of the delivery alternatives among their key performance indicators (cost, distance and time). The questionnaire respondents indicated that they both prefer the pickup point service after home delivery for customers and after shop pickup for retailers. Depending on the level of investments that grocery retailers would like to implement and according to the experiment results, it could be concluded that pickup point solution is the best logistical strategy for retailers to start with.Jerash Private University, Jordan

What Does Autonomous Adaptation to Climate Change Have to Teach Public Policy and Planning About Avoiding the Risks of Maladaptation in Bangladesh?

Climate vulnerability represents a highly complex public policy challenge for government due to its interaction with diverse social, political, economic, and ecological factors across scale. The policy challenge is further exacerbated when rural livelihood opportunities depend on multiple land use practices within shared social-ecological systems and adaptation actions related to one practice affects the others. In such cases, it becomes likely that national and regional-level adaptation plans will result in maladaptive trajectories if local context and properties are not carefully considered. This review highlights the importance of this issue to public policy using the case of climate change adaptation planning in Bangladesh to highlight how national and regional-level planned adaptation processes could benefit from paying closer attention to the autonomous adaptation processes occurring at local levels. Focussing on the northeastern floodplain region, an area dominated by wetland ecosystems, high climate vulnerability, and diverse and complex land use practices, we examine some of the community-level adaptation actions that are being undertaken in response to climate change and contrast these with national-level adaptation planning strategies and actions. We then analyze how the planned adaptation actions taken by government may actually end up being maladaptive, either by shifting or rebounding vulnerability. We conclude that government adaptation planning would benefit from a greater focus on learning and scrutinizing the autonomous adaptation of communities to climate stress before making significant resource allocation decisions

An Investigation into the Positive Visual Experience Design for the Elderly

Visual impression is the first impact on human perception through receiving and assessing the external information observed by the eyes. Therefore, product appearance is closely linked to the human’s visual experience and can affect human’s mood throughout the process of information perception and product manipulation. Generally, visual ability declines as age increases, which can lead to visual impairment and unpleasant moods among the elderly. For the elderly, there is a need to improve the quality of the visual experience in design. The aim of this research is to explore feasible methods to discover the consistency between subjective desires and objective environmental reactions in order to provide the optimal pleasurable visual experience conditions for elderly individuals in design. The objectives are 1) To examine the common elderly visual experience features in relation to physiological and psychological effects, specifically reflected in vision, perception, and emotion; 2) To determine a positive visual experience framework for elderly-focused design based on visual experience consideration; 3) To develop positive visual experience assessments and test methods specially designed for the elderly in order to gather information and data about subjective desire and objective reaction to objects; 4) To analyze the results of consistency between subjective preference and objective attraction in order to form a positive visual experience for elderly individuals. This research describes the research process and its findings. Initially, the introduction of the thesis presents the research motivations and background, with its aim and objectives defined. Related literature supporting the research is then examined for further understanding of aging, visual experience and relevant emotional issues, and research methodologies. Based on this understanding of the elderly visual experience and visual experience behavior, along with observations of purchasing processes, interviews with the elderly, and interviews with experts, a set of assessment tools (VPTs) was developed for assessing the elderly visual experience factors from the two perspectives of subjective preference and objective attraction. Based on statistical analysis, the elderly general cognitive features, and a series of positive visual experience factors that affect the emotional mood of the elderly were determined. The results of the investigation contribute to design for the elderly with positive visual experience factors identified for enhancing the elderly satisfaction in their visual experiences and manipulating product design to create a positive emotional state. This VPTs assessment tool can also be recommended as a reference for investigating into other various target groups’ visual experience features

Methodology to predict construction contractors’ performance using non-price measures

Despite being one of the largest industry sectors in the world, construction continues to suffer from underperformance. Contractors are the driving force behind built assets, and selecting high-performing contractors is crucial to the success of construction projects. However, the industry lacks a systematic and purpose-driven method of assessing contractors’ performance using objective metrics. Furthermore, contractors do not have a systematic way to gauge their own performance in the pursuit of continuous improvement. Although there are numerous approaches to the measurement of contractors’ performance, the literature suggests that most are complicated and highly dependent on data that are difficult to attain. The research presented in this thesis addresses this knowledge gap by creating a model for predicting construction contractors’ performance based on directly attributable measures that are quantitatively measurable and easily accessible. The findings of this research make a number of contributions to theory and practice. The developed performance model—the Contractors’ Performance Index (CPIx) provides a performance score based on seven non-price CMoPs. As the CPIx is based on factors that are within the control of the contractor, it provides a fair and independent assessment of performance that is not influenced by other factors. In an industry significantly driven by pricebased decisions that are solely based on non-price measures, the CPIx shifts the focus towards other aspects such as quality, health and safety, sustainability and productivity when evaluating performance, leaving price based measures for commercial considerations. Contractors can use the CPIx to self-evaluate their levels of project and organisational performance. If implemented as a sector-based performance evaluator, it can then be used to develop industry benchmarks for different categories of construction. The CPIx is presented as a prototype mobile application that can be conveniently used by various stakeholders to track performance within the construction industry

Evaluating the Effectiveness of the E-learning Experience in Some Universities in Saudi Arabia from Male Students’ Perceptions

ABSTRACT This study applies social science methodology to the innovation of e-learning so that decision makers and other stakeholders can assess aspects of its effectiveness, to provide a more secure base for action. In this study, e-learning’s effectiveness was evaluated at two universities in Saudi Arabia, through male learners’ perceptions. Some account was taken of variables to assess statistically significant differences in their views. The data was collected by mixed methods: using a questionnaire from a sample of 300 learners and a focus group interview attended, later, by 21 learners. The findings showed that e-learners believe that they are able to learn autonomously using all features made available by the technology. They reported that they were motivated by the interactivity of e-learning and pursued their courses with intensity and success. There was positive agreement in all four dimensions considered by the research. Significant variables within this positive rating were previous e-learning experience and ICT skills. The study also collected learners' views about the positives and negatives of e-learning, its requirements and barriers, as well as learners' suggestions for the development of e-learning. Learners appreciated the opportunities offered by e-learning and the way it supported their studies, facilitating communication and accommodating their learning needs and circumstances. They recognised that it helped to meet an increased demand for learning. On the other hand, they noted some hazards to physical and social health and some confusion arising from the diversity of information accessible through ICT. They felt improvements could be made by planning, training and by specialized personnel. Most of the barriers they noted arose from infrastructural weaknesses and lack of acceptance of e-learning. Respondents said they were aware of financial constraints and of language barriers. Universities, working closely with communities and the private sector, could address many of these identified issues in products and infrastructure. This study concludes with some recommendations as well as suggestions for future research
