A Critical Review of High and Very High-Resolution Remote Sensing Approaches ...rsmahabir
Slums are a global urban challenge, with less developed countries being particularly impacted. To adequately detect and map them, data is needed on their location, spatial extent and evolution. High- and very high-resolution remote sensing imagery has emerged as an important source of data in this regard. The purpose of this paper is to critically review studies that have used such data to detect and map slums. Our analysis shows that while such studies have been increasing over time, they tend to be concentrated to a few geographical areas and often focus on the use of a single approach (e.g., image texture and object-based image analysis), thus limiting generalizability to understand slums, their population, and evolution within the global context. We argue that to develop a more comprehensive framework that can be used to detect and map slums, other emerging sourcing of geospatial data should be considered (e.g., volunteer geographic information) in conjunction with growing trends and advancements in technology (e.g., geosensor networks). Through such data integration and analysis we can then create a benchmark for determining the most suitable methods for mapping slums in a given locality, thus fostering the creation of new approaches to address this challenge.
The document discusses an evaluation of metadata usage and distribution in a linked data environment. It analyzes datasets from different institutions that mapped manuscript metadata to the Europeana Data Model (EDM) and a DM2E model. The evaluation aims to discover similarities and differences between datasets from different mapping institutions. It finds variations in usage of classes, properties, ontologies, and structural metrics like predicate-object-equality-ratio. The conclusion is that linked data quality assurance is important and people have a strong influence on metadata mapping.
Gender differences in OpenStreetMap contributor activitiy, editing and taggin...Zoe Gardner
This document summarizes research into gender differences in contributions to OpenStreetMap. The main findings are: 1) Men are statistically more active contributors than women, based on number of days editing and changesets. 2) Men contribute more edits of nodes, ways and relations than women. 3) There are nuanced differences in tagging behaviors between men and women, with men demonstrating more variance in the types of features they tag. The paper examines these differences to understand how gender imbalance may impact the representation of places in the crowdsourced map.
Networks of scientific cooperation between cities: a multiscalar analysisMarion Maisonobe
This document discusses analyzing scientific collaborations between cities using bibliometric data from the Science Citation Index. The objectives are to geocode author addresses, assign publications to urban areas, and analyze the global network of interurban collaborations from 1999-2008. Results show a growing dispersion of scientific activities across multiple scales, as well as significant growth in collaborations within and between countries. Community detection methods reveal clusters of frequently collaborating countries and cities, with some regional research areas like Europe remaining stable over time. Future work should take multiscalar approaches to better understand the structures and dynamics of collaborative scientific networks.

Sci 2011 big_data(30_may13)2nd revised _ loetHan Woo PARK
This document summarizes a research paper that analyzes social and semantic networks related to big data research. It describes how the authors collected data on internationally co-authored papers from the 2011 SCI database using search terms related to big data. It then summarizes the two research questions addressed: 1) What is the structural pattern of international co-authorship networks in big data research? 2) What is the semantic structure of paper titles in this field? The authors analyzed the data using social network analysis and semantic network methods to address these questions and better understand patterns of collaboration and terminology use in emerging big data science.
The document discusses open geo-spatial data and spatial data infrastructures. It provides an overview of key concepts including open data, geographic information systems (GIS), spatial data formats and standards, and spatial data infrastructure initiatives like INSPIRE which aim to make spatial data interoperable across Europe. The document also discusses global open data efforts like the Group on Earth Observations (GEO) and GEOSS, as well as principles for open data and how data can be made more open and accessible.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
The interaction between transport, land-uses and travel patterns produce diverse transportation problems in urban cities with traffic congestion as the most visible manifestation. Traffic congestion is a frequent phenomenon in most cities around the globe. This paper reviews the interaction between land-use traffic congestion through published literature. The objective of this study is to encourage and provide researchers with future research directions in land-use and traffic congestion. For this purpose, a systematic review was performed analysing 45 articles from the year 2010 to 2020 using a descriptive approach. Subsequently, the results of the study show that although the interaction between land-use and traffic congestion has gained currency in developed countries far less is known on this subject in developing parts of the world, though new evidence is steadily accumulating. Consequently, limitations of this work are presented, opportunities are identified for future lines of research. Finally, the conclusion confirms the need for further research addressing the methodological concerns.

Scratchpads are virtual research environments that allow taxonomic and biodiversity data to be collected, curated, analyzed, published, and shared in a digital, open, and linked manner. They provide a seamless workflow for data by hosting websites for communities to enter and structure data using standardized modules. This facilitates dissemination of research through open access publishing of datasets, descriptions, keys, and more without reformatting. Major projects like e-Monocot demonstrate Scratchpads' ability to aggregate data from various sources into an integrated portal.

Slides from a seminar delivered for pepnet at the University of Leeds 28 Nov 2018. Thanks to Charlotte Perry-Houts for extra content:
From peer reviewed journal articles, to assorted reports and grey literature, to datasets comprising numerical, textual or multimedia files; we generate thousands of research outputs.
In this session, Kirsten Thompson (OD&PL) and Nick Sheppard (Library) will discuss strategies for increasing quality online engagement with that research. We will explore how you can use ‘alternative metrics’, more commonly known as ‘altmetrics’, to monitor such engagement. Altmetrics can help to showcase the reach of your work, supplement grant and tenure applications, identify new audiences, and connect with other researchers in your discipline.
In the age of “fake news”, academics have a responsibility to share their expertise beyond the Ivory Tower. We’ll show you how to ensure all these disparate outputs are properly curated in university repositories with a Digital Object Identifier (DOI). There will also be an opportunity to learn about and contribute to the Library led Data Management Engagement Award, a first-ever competition launched to elicit new and imaginative ideas for engaging researchers in the practices of good Research Data Management (RDM).

To Thread or Not to Thread: The Impact of Conversation Threading on Online Di...Pablo Aragón
Online discussion is essential for the communication and collaboration of online communities. The reciprocal exchange of messages between users that characterizes online discussion can be represented in many different ways. While some platforms display messages chronologically using a simple linear interface, others use a hierarchical (threaded) interface to represent more explicitly the structure of the discussion. Although the type of representation has been shown to affect communication, to the best of our knowledge, the impact of using either one or the other has not yet been investigated in a large and mature online community.
In this work we analyze Menéame, a popular Spanish social news platform which recently transitioned from a linear to a hierarchical interface, becoming an ideal research opportunity for this purpose. Using interrupted time series analysis and regression discontinuity design, we observe an abrupt and significant increase in social reciprocity after the adoption of a threaded interface. We furthermore extend state-ofthe-art generative models of discussion threads by including reciprocity, a fundamental feature to explain better the structure of the discussions, both before and after the change in the interface.
This document discusses visualizing and analyzing the PUBMED dataset. It describes creating co-authorship networks showing nodes, edges, and properties over time. It also analyzes researchers' academic throughput by looking at years of first/last publication, number of publications, and duration of activity. Finally, it examines terminology evolution by analyzing word terms in 5-year title corpora. The analysis uses Pandas for data manipulation, NetworkX for network analysis, NLTK for natural language processing, and Matplotlib for plotting.

The document discusses early research in webometrics, which is the study of quantitative aspects of the construction and use of information resources on the web. It describes two seminal webometric studies - one that analyzed the small-world link structure across UK university websites, and another that examined genre connectivity and how different page genres function as link providers and receivers. The studies found that computer science sites often connect topics, personal pages provide links that increase cohesion, and genre and topic drift along links helps create short paths in the small-world structure of the web.

An illustrated typology of scientific agglomerations forms in the world, 2000...Marion Maisonobe
This document presents a typology of scientific agglomeration forms based on an analysis of publication data from 2000-2010. It identifies 5 types: 1) monocephalic agglomerations with a single center; 2) agglomerations with a single decentralized center, including those with a more dynamic suburb; 3) agglomerations with multiple decentralizations; 4) two close agglomerations within or across borders; 5) emergence of new centers. Examples of each type are shown on maps with publication data from two time periods to illustrate spatial configurations and evolutions.
The pyrenees: a spatially rooted analysis of scientific research performed on...Marion Maisonobe
The document summarizes a research project analyzing scientific studies of the French Pyrenees mountains over time. It finds that the majority of publications on the Pyrenees from 1999-2012 were produced by researchers located in Toulouse, France, with the second highest number coming from Paris. The studies covered various disciplines but most focused on geology and astronomy. The research aims to further analyze collaboration networks and map specific study sites to better understand the spatial dimensions and heritage of Pyrenees research.
This document describes an R workshop on analyzing graphs and networks. It discusses representing graphs as mathematical objects in R and available R packages for graph analysis.

ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

Authoring a personal GPT for your research and practice: How we created the Q...Leonel Morgado
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.
The binding of cosmological structures by massless topological defectsSérgio Sacani
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...Leonel Morgado
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
PPT on Direct Seeded Rice presented at the three-day 'Training and Validation Workshop on Modules of Climate Smart Agriculture (CSA) Technologies in South Asia' workshop on April 22, 2024.
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.
Immersive Learning That Works: Research Grounding and Paths ForwardLeonel Morgado
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.

Post-doctoral fellowship CNRS, FR INCREASE (3707), Poitiers
2. Studying the dynamics of science
• A rather old question in philosophy, sociology and history of science
• A rather new question in geography :
S. Shapin, D. Livingstone the spatial turn in STS and history of science
With three approaches:
• The« spatial scientometrics » trend (Frenken et al. 2009)
• The qualitative and historical trend mainly developed in the UK (Besse,2010)
• A third pathway combining social studies of science and spatial scientometrics
(Grossetti, Milard et Maisonobe, 2015)
3. Multiscalar analysis
To follow the dynamics of science at the world level
Several level of spatial analysis are relevant :
- continental
- macro-regional
- national
- regional
- urban
4. Multiscalar analysis
To follow the dynamics of science at the world level
Several level of spatial analysis are relevant :
- continental
- macro-regional (community detection)
- national
- regional
- urban (clusters of publishing localities)
5. Research questions
1. How is the world system of science evolving (national contexts, regions of the world,
interurban connections) ?
2. How does a speciality can emerge and develop at the world level with connections
being activated between all the places that are involved in it ?
6. The world system of science expansion
• Continuous growth of research activities and publications
• A proliferation of sites of activity (Shofer & Meyer, 2005)
• An increase in the number of higher education personnel (UNESCO, 2010)
A re-balancing of the global scientific output over the last thirty years at the
country and at the city level (Grossetti et al., 2014)
• What about the structure of the world network of collaboration ?
• Is the globalization of scientific production activities accompanied by a blurring of national
contexts to the benefit of global collaborative networks or on the contrary do national and
macro-regional areas still have a structuring effect on the distribution of scientific
cooperation ?
7. Data and method
• In 2013, more than 10 000 revues and about 2 millions of publications indexed in
the Web of Science (SCI Exp, SSCI, AHCI)
1. GEOCODING : Almost 98% of all WoS publications (articles, reviews, letters)
have been geocoded (1999-2014) = 19 millions publications
2. CLUSTERING : After the geocoding, the publication data are clustered by urban
areas
