IoT-based air quality monitoring systems for smart cities: A systematic mapping study

The increased level of air pollution in big cities has become a major concern for several organizations and authorities because of the risk it represents to human health. In this context, the technology has become a very useful tool in the contamination monitoring and the possible mitigation of its impact. Particularly, there are different proposals using the internet of things (IoT) paradigm that use interconnected sensors in order to measure different pollutants. In this paper, we develop a systematic mapping study defined by a five-step methodology to identify and analyze the research status in terms of IoT-based air pollution monitoring systems for smart cities. The study includes 55 proposals, some of which have been implemented in a real environment. We analyze and compare these proposals in terms of different parameters defined in the mapping and highlight some challenges for air quality monitoring systems implementation into the smart city context

Citizen Science and Geospatial Capacity Building

This book is a collection of the articles published the Special Issue of ISPRS International Journal of Geo-Information on “Citizen Science and Geospatial Capacity Building”. The articles cover a wide range of topics regarding the applications of citizen science from a geospatial technology perspective. Several applications show the importance of Citizen Science (CitSci) and volunteered geographic information (VGI) in various stages of geodata collection, processing, analysis and visualization; and for demonstrating the capabilities, which are covered in the book. Particular emphasis is given to various problems encountered in the CitSci and VGI projects with a geospatial aspect, such as platform, tool and interface design, ontology development, spatial analysis and data quality assessment. The book also points out the needs and future research directions in these subjects, such as; (a) data quality issues especially in the light of big data; (b) ontology studies for geospatial data suited for diverse user backgrounds, data integration, and sharing; (c) development of machine learning and artificial intelligence based online tools for pattern recognition and object identification using existing repositories of CitSci and VGI projects; and (d) open science and open data practices for increasing the efficiency, decreasing the redundancy, and acknowledgement of all stakeholders

Global and regional sourcing of ICT-enabled business services: upgrading of China, Hong Kong and Singapore along the global value chain

Offshoring, as part of globalisation, first started decades ago with manufacturing processes disintegrated along the global value chain and dramatically redistributed to low-cost regions. The next global shift of work involving ICT-enabled business services has arisen since the 1990s, especially featuring the success of India’s supplier role. The possibilities for the Global South to move up the value ladder are well demonstrated by the achievements of the newly industrialised economies in East Asia in the first shift and of India in the second. In the services sector, however, potential for upgrading is conditioned by quality-based elements, such as trust, culture and language, which vary both between producing and market areas. Flows are increasingly multi-directional, requiring attention to the neglected issue of demands from fast-growing Southern economies. So how do locations and firms in the Global South attempt to upgrade in the regime of rising services offshoring? The Indian experience especially in serving Anglophone markets in the Global North has been widely documented – but not that of East Asian economies, with their distinct characteristics and strong historic, ethnic and cultural ties with each other. This study examines the upgrading possibilities and constraints of China, Hong Kong and Singapore along the global services chain. For cross-case analysis, it focuses on three specific sets of services, including information technology, finance and accounting, and customer contact services. The concepts of global value chain, competitive advantage and capabilities are applied to reconstruct the phenomenon of services offshoring from both the demand and supply perspectives in the selected locations, and synthesise the dynamics between locational characteristics and firm strategies. A series of distinct upgrading strategies are identified, involving mixes of manufacturisation, knowledge-intensification and deepening relational capabilities to exploit both regional advantages of language/cultural proximity and established global links

Services-driven growth and India’s changing socio-economic fabric:Emergence of a new middle class and the contribution of Mumbai’s IT-eS industry to its formation

The emergence of the offshore-services industry is claimed to have significantly altered the socio-economic fabric of India, giving rise to the formation of a ‘new’ middle class. This thesis explores the contribution of Mumbai’s offshore-services industry to a new middle class formation, in the broader context of the rise of such a class in India in general. The concept of class is used as the central analytical tool as it encompasses multiple dimensions along which societies are stratified to provide a holistic understanding of how societies function and how socio-economic transformations take place. The theoretical framework of this thesis is anchored on Bourdieu’s Forms of Capital. It studies changes in the possession and distribution of economic and cultural capitals and their conversion into new forms of capital in India in general, along with the specific role of offshore-services in bringing about such a transformation

Environmental risk assessment in the mediterranean region using artificial neural networks

Los mapas auto-organizados han demostrado ser una herramienta apropiada para la clasificación y visualización de grupos de datos complejos. Redes neuronales, como los mapas auto-organizados (SOM) o las redes difusas ARTMAP (FAM), se utilizan en este estudio para evaluar el impacto medioambiental acumulativo en diferentes medios (aguas subterráneas, aire y salud humana). Los SOMs también se utilizan para generar mapas de concentraciones de contaminantes en aguas subterráneas simulando las técnicas geostadísticas de interpolación como kriging y cokriging. Para evaluar la confiabilidad de las metodologías desarrolladas en esta tesis, se utilizan procedimientos de referencia como puntos de comparación: la metodología DRASTIC para el estudio de vulnerabilidad en aguas subterráneas y el método de interpolación espacio-temporal conocido como Bayesian Maximum Entropy (BME) para el análisis de calidad del aire. Esta tesis contribuye a demostrar las capacidades de las redes neuronales en el desarrollo de nuevas metodologías y modelos que explícitamente permiten evaluar las dimensiones temporales y espaciales de riesgos acumulativos

You are what you measure! But are we measuring it right? An empiric analysis of energy access metrics based on a multi-tier approach in Bangladesh

Measuring energy access through binary indicators is insufficient, and often, even misleading. In this work, the SE4ALL global tracking framework, and the recently introduced ESMAP multi-tier approach, is critically discussed analyzing questionnaire based primary data from rural Bangladesh. The performance of different energy interventions is evaluated using the new tier framework. The challenges in its application lie in reliable data collection, adequate gradation of indicators, and an effective algorithm for the tier assignment based on the specified set of attributes. The study showcases very high sensitivities to parameter changes, different algorithms, and data requirements. The results reveal a clear trade-off between capturing the multi-dimensionality of energy access and the simplicity of an easy to use global framework. Suggestions to improve the measuring approach are made and conclusions are drawn for possible implications of the tier framework for different energy service offers in the market. Strengths and weaknesses of the present measurement scheme are discussed and country specific results interpreted through targeted gap analysis for future policy advice
