What opportunities are there with Ag Biotech that remain unrealized? Important crops have been engineered, by public and government labs, so solve problems for the environment, the farmer, the needy and the consumer. These remain unused due to high regulatory barriers and small farm industry fear of public backlash.
This document discusses success stories of developing disease-resistant plant varieties through conventional breeding and genetic engineering techniques. It provides examples of transgenic crops with enhanced traits like increased yield, nutritional quality, stress tolerance and pest resistance. Specifically, it mentions golden rice which was engineered to produce beta-carotene, and virus-resistant plants containing viral coat proteins. The document also discusses delayed fruit ripening tomatoes and insect-resistant Bt crops. Overall the document outlines major advances in developing stress-tolerant and nutritionally-enhanced transgenic crops.
This presentation represents the Genetic use restriction technology (GURT), also known as terminator technology. This presentation explain the advantages and impact of terminator technology.
The document discusses several genetically engineered plants including Bt crops, Golden Rice, and Flavr Savr tomato. Bt crops contain a gene from Bacillus thuringiensis that produces a toxin harmful to certain insects, protecting the plant. Golden Rice was engineered to produce beta-carotene in the endosperm to address vitamin A deficiency. Flavr Savr tomato was modified using antisense RNA technology to reduce polygalactouronase levels and slow fruit softening for a longer shelf life.
This document provides an overview of genetically modified crops. It discusses the history and development of GM crops, including the first transgenic animal and plant. The major commercialized crops are corn, cotton, soybean and canola. GM crops were developed to provide traits like pest resistance, herbicide tolerance, and increased nutrition and yield. The document outlines the process used to develop a GM crop and notes both potential benefits like increased yields and food security, as well as risks to human and environmental health that are areas of ongoing research and debate. Bt cotton, engineered to produce an insecticide, was the first GM crop approved in India. The presentation concludes by questioning whether GM crops have actually increased global food security and access to food.
This document discusses genetically modified crops. It begins by defining genetically modified crops as crops that have been manipulated through genetic engineering techniques to introduce genes from unrelated organisms. This can produce new traits not present originally. The document then describes several techniques used to produce genetically modified crops, including recombinant DNA technology and direct gene transfer methods like particle bombardment. It provides examples of genetically modified crops and their benefits, such as Flavr Savr tomato with improved shelf life, Golden Rice with increased vitamin A, and Bt crops with built-in pest resistance. The document discusses both potential benefits and risks of genetically modified crops.

This document discusses managing diseases in cassava to achieve high yields. It recommends identifying pathogens, understanding their disease cycles, avoiding pathogens through good quality planting material from disease-free areas, and controlling pathogens using resistant varieties, chemical protection of cuttings, and cultural practices like rotations and drainage. Introducing foreign pathogens through imported planting material poses huge risks and should be avoided. With responsible practices like the "Corner of Prosperity" method for selecting clean cuttings, cassava farmers can select high-yielding varieties and produce healthy crops despite disease pressures.
This document summarizes Asian seed potato production systems that are similar to systems in the Highlands of Africa. It describes four potato cropping zones in China and locations in Vietnam, China, and the Philippines between 1500-3000 meters in elevation that face constraints of late blight, bacterial wilt, and viruses. It outlines national programs over 30 years that have developed varieties resistant to these diseases, demystified tissue culture, and developed simple on-farm seed programs. Key varieties developed include C88 and Igorota, which have disease resistance and yields up to 80 tons/hectare. Farmer participation in tissue culture and seed multiplication programs has been crucial to success.
Bt cotton is a genetically modified variety of cotton that expresses a gene from the soil bacterium Bacillus thuringiensis (Bt), which produces a protein that is toxic to certain insect pests like bollworms but harmless to other organisms. It was developed to control major cotton pests that can cause significant yield losses. Bt cotton reduces the need for insecticide use and promotes more environmentally friendly cotton cultivation while protecting yields. The Bt gene works by being toxic only to insects that ingest the Bt protein, but is safe for other animals and humans.
Transgenic crops are genetically modified crops containing genes artificially inserted from another species. The first GM crop was a tobacco plant in 1982, and the first approved for sale in the US was the FlavrSavr tomato in 1994. GM crops are developed using genetic engineering techniques to speed up traditional breeding and introduce a wider variety of genes. Potential benefits include increased yields, insect and disease resistance, and improved nutrition. However, there are also concerns about the impacts on human and environmental health.

Abstract
Late blight (LB) of potato, caused by Phytophthora infestans, is one of the most devastating diseases of potato (Solanum tuberosum L.) in Africa and in many parts of the world. Conventional cross-breeding to develop resistance has met with challenges of length of breeding time and durability of resistance in the hybrids developed. Three resistance genes (RB, Rpi-blb2, and Rpi-vnt1.1) previously cloned from two wild potatoes, S. bulbocastanum and S. venturii, and the availability of a potato transformation system allowed us to introduce all three genes into cultivated varieties in order to develop durable resistance. The genes were introduced into two cultivated potato varieties ‘Desiree’ and ‘Victoria’. The genetically modified (GM) potatoes generated were field-evaluated in Uganda at the Kachwekano Zonal Agricultural Research and Development Institute in Kabale. Twelve transgenic events of the variety ‘Desiree’ and one of the variety ‘Victoria’ were tested in three replications, each consisting of randomised complete block design of plots of 15 plants each. The results indicate that all 13 transgenic events are completely resistant to LB disease. These GM potatoes, if incorporated into the seed potato system for uptake by farmers in Africa and elsewhere, offer a great opportunity for durable, cost-effective, and environmentally friendly solution to the management of LB disease in potato. Consequently, farmers could discontinue their current practice of spraying toxic chemicals to control the disease. The next steps for further development of these lines into commercial varieties for Africa and the associated deregulation challenges are discussed
Genetically modified crops are plants whose DNA has been modified using genetic engineering techniques to enhance desired traits such as increased herbicide resistance or improved nutritional content. While conventional breeding methods are time-consuming and imprecise, genetic engineering allows for more precise introduction of specific genes. However, there are also concerns about the environmental and health impacts of GM crops, including the potential for gene transfers to cause unintended consequences or allergic reactions in humans.
Genetically modified organisms (GMOs) can be engineered in several ways to alter plant traits. Some common applications include making crop plants resistant to herbicides, allowing farmers to spray fields without damaging crops. Corn, soybeans, and cotton in the US are often engineered for herbicide resistance. GMOs are also used to improve crop quality, increase nutrient levels, and produce pharmaceuticals and vaccines in plants. However, the ethics and impacts of GMO technology are debated, with concerns about environmental effects, corporate control of seeds and genes, and impacts on developing countries.
Terminator gene technology refers to plants that have been genetically modified to render sterile seeds at harvest.
Genetic use restriction technologies (GURTs) are the name given to experimental methods, described in a series of recent patent applications and providing specific genetic switch mechanisms that restrict the unauthorized use of genetic material (FAO, 2001a) by hampering reproduction (variety-specific V-GURT) or the expression of a trait (trait-specific T-GURT) in a genetically modified (GM) plant.

Loss of a microRNA molecule has striking effects on several yield-related traits in indica rice. Researchers from the National Centre for Biological Sciences in India found that miR397, which is barely detectable in domesticated rice, accumulates to high levels in wild rice. miR397 silences several laccase genes, reducing woody tissue formation. When miR397 expression was increased in domesticated rice, the plants resembled wild rice with low yields. Modifying miR397 expression could improve rice yields and traits in wild and cultivated varieties. The rice gene bank at the International Rice Research Institute conserves 136,000 rice varieties and will receive $1.9 million annually from the Crop Trust to fund operations and distribute seeds for climate-
The document discusses genetically modified crops (GMCs), including their definition, methods of genetic modification, potential benefits and risks. Some key points:
- GMCs are plants whose genetic characteristics have been altered by inserting genes from other species, conferring traits like pest/disease resistance, herbicide tolerance, drought tolerance, or improved nutrition.
- Potential benefits include increased crop yields and reduced need for pesticides, but risks include possible human health impacts and environmental effects like gene transfer to non-target species.
- Global adoption of major GM crops like soybean and maize has increased significantly since their introduction in the late 1990s, though uptake varies by country. Vietnam has conducted research on GM rice,
This document provides an overview of transgenic crops, including:
1) A brief history of transgenic crop development and the governing policies surrounding the technology.
2) A summary of the main agricultural crops that have been genetically modified, their expressed characteristics, and their market roles.
3) A discussion of unintended consequences, economic considerations, safety concerns, and implications of transgenic crops for sustainable agriculture.

Genetically modified organisms are defined as organisms that have had their DNA altered in a way that does not occur naturally, such as by transferring genes between non-related species. The first GM plants and animals were created in the 1970s-1980s and included E. coli bacteria containing human genes and transgenic mice. Since then, many other GM crops have been developed including Bt cotton in 1996, which resisted lepidopteran insects without the need for pesticides. More recent developments include safflower plants producing human insulin in 2008 and poplar trees with altered cellulose and lignin levels in 2009. Overall, GM technology has allowed for the introduction of useful traits like increased yield, herbicide and pest resistance, and nutritional enhancements
This document provides information about genetically modified crops. It discusses how GM crops are produced through genetic engineering by inserting genes from other organisms. It then discusses GM crops that have been approved for commercial production, including insect-resistant cotton, maize, and soybean as well as herbicide-tolerant soybean. The document also discusses the global area planted with biotech crops annually and countries that grow the most biotech crops. It outlines some pros and cons of GM crops and how they are regulated in different countries including the US, EU, and India.
1) The document discusses the increasing global demand for fish and the role of aquaculture in meeting this demand. It notes that fish consumption has doubled since the 1950s and aquaculture is becoming increasingly important.
2) It provides an overview of fish genetics and its application to aquaculture, including selective breeding techniques to improve genetic stocks, transgenic fish, and DNA vaccines. Chromosomal manipulation techniques like gynogenesis, androgenesis, and polyploidy are also covered.
3) The conclusion states that while Indian fisheries science has made progress in genetics research, more work is still needed to commercialize techniques and generate applied products and processes to further develop aquaculture and fisheries management.
This document discusses how radiation has significantly improved medicine and agriculture. In medicine, radiation is used to sterilize medical equipment. In agriculture, radiation has led to higher crop yields through developing new crop varieties that are hardier, have higher yields, and are resistant to diseases and drought. Over 2,250 new crop varieties have been developed using radiation, improving global food supplies. Radiation has also been used to improve animal health by developing more effective vaccines and feed additives.
This document summarizes research on developing genetically modified potatoes resistant to late blight disease for farmers in Africa. Key points:
- Researchers cloned resistance genes from wild potato relatives into popular varieties in East Africa like Victoria and Desiree.
- In confined field trials in Uganda, transgenic events showed extreme, high, and moderate resistance to late blight, while susceptible controls were heavily infected.
- Stakeholders like farmers and government officials visited the trials and responded positively to the drought-resistant GM potatoes.
- Further multi-location trials are planned, and while GMO regulations vary in Africa, most smallholder farmers would adopt GM crops if they offer promised benefits like disease resistance.

Exploitation of hybrid seed production in Vegetables by Atma ram meenaATMA RAM MEENA
The document discusses the history and development of hybrid seed production in vegetables. It notes that the first hybrid eggplant was developed in 1924 in Japan, followed by hybrids of other crops in subsequent decades. Methods for large-scale hybrid seed production were established using mechanisms like cytoplasmic male sterility, self-incompatibility, and gynoecious lines. These methods are now commercially used for many vegetable crops and have increased yields, uniformity, and stress resistance compared to open-pollinated varieties. The global hybrid vegetable seed market continues to grow due to rising world population and seed demand.
This document summarizes consumer research conducted to create a niche maternity outerwear line. It analyzes the target market demographics of married or single mothers ages 23-35 who have graduated college. Market surveys found these mothers want comfortable, classic styles in neutral colors like black, grey and cream between $50-75. Inspiration comes from pre-18th century historic costumes like ruffs and draped dresses as well as post-18th century styles like spencer jackets and bishop sleeves. Cultural influences on fashion from items like Indian bangles and Japanese kimonos are also discussed. The document addresses issues like using environmentally friendly antibacterial fabrics and the fashion industry's responsibility to promote healthy body images in models.
Yam is the main staple crop in Nigeria, which is a large tuber that is harvested and can last up to 6 months. Yam farming requires clearing the land, planting slices of yams for planting, and replanting after 3 months. There are large festivals held called the New Yam Festival that celebrate the harvesting of the new yam crop each year and feature much food. Other key crops and foods in Nigeria include kola nuts, palm wine, palm oil, maize, melons, and beans.

A proposal for governance of sustainability in agriculture. Gérard RassJoanna Hicks
This document proposes a governance structure for sustainable agriculture. It suggests:
1) Establishing stakeholder dialogs between farmers, citizens, and policymakers to agree on objectives and sustainability criteria.
2) Developing indicators to measure farm practices' impacts on ecological services and sustainability over time.
3) Creating an Institute for Sustainable Agriculture (IAD) to identify and use indicators to assess 160 farms across 7 sustainability themes.
4) Developing a payment system for ecological services (PES) based on IAD indicators to incentivize sustainable practices.
Iron-deficient Indian children under the age of three who ate traditionally-prepared porridges and flat bread made from iron-rich pearl millet flour absorbed substantially more iron
The document discusses the state of global agriculture and its effects on ecosystems. It notes that 15 of 24 key ecosystem services have been degraded or unsustainably used in recent decades due largely to expansion of agriculture. About half of original forests have been lost to agriculture. Agriculture appropriates one third of the planet's net primary productivity and is a major driver of biodiversity loss and carbon emissions. Feeding a growing population while reducing these impacts will require intensifying production on existing farmland and improving sustainability through techniques like irrigation, fertilization, and conservation agriculture.
Promoting Small Businesses for Internally Displaced Persons Toluwalola Kasali
This document proposes three quick impact projects to promote economic integration among internally displaced persons in North-East Nigeria. The three proposed projects are: 1) A petty trading project that would provide business grants and training to displaced women. 2) A tailoring project also aimed at women providing skills training and equipment. 3) A farming project that would provide skills training, start-up grants and potentially access to land for displaced men. The document outlines costs, timelines, and expected outcomes for each project, arguing they could provide sustainable livelihoods and restore dignity for displaced persons.

Goals.
The secret to improving farm productivity and prosperity by sotonye angaSotonye anga
Precision farming uses GPS and soil sampling to create detailed maps of farmlands, showing variability in soil nutrients. This allows farmers to understand their soil's strengths and weaknesses, avoid guesswork, and ensure optimal planting and fertilization. As a result, farmers can increase yields, improve incomes, and lift themselves out of poverty. The document outlines the process, from soil sampling to producing recommendation reports, and argues this approach aligns with Nigeria's agricultural goals and could create many new jobs.
Setting the agenda for nigeria's next agric minister by sotonye angaSotonye anga
Achieving food security does not require a decade; I believe it can be done in less than 2 years. Therefore, for the office of the Minister of Agriculture we need a visionary leader, who is experienced and skilled in the field of Agri-business as well as determined to drive growth in the sector, creatively attract and engage youths in different aspects of Agribusiness and provide an enabling environment for private sector agribusinesses to thrive.
The Bharwads are a Hindu pastoral caste found in Gujarat, India. They traditionally practice nomadic pastoralism, raising livestock like cattle and goats and migrating in search of fresh pastures. The Bharwads identify strongly with their pastoralist lifestyle and customs, including distinctive styles of dress. Most Bharwads have low levels of education and rely on agricultural labor and livestock rearing for income.

The document summarizes the impacts of the Green Revolution from the 1940s-1970s, which aimed to increase global agricultural production through new technologies. It led to increased cereal crop yields through high-yielding varieties, irrigation infrastructure, and chemical fertilizers and pesticides. This boosted food availability and reduced famine in countries like India and Mexico. However, it also had negative consequences like groundwater depletion, increased monocultures, and worsening inequality as small farmers struggled with high input costs. The document then discusses the introduction of GE crops and notes both arguments for reducing world hunger but also concerns about the impacts on bees, weeds, and Indian farmer suicides.
This document discusses IITA's yam germplasm collection and conservation efforts. It notes that IITA's yam collection contains over 3,800 accessions originating from West and Central African countries. The collection is conserved using both in vitro and on-farm methods. Characterization of the collection involves morphological and genetic analysis to understand diversity. The collection is available for research and breeding through IITA's genebank system with the goal of supporting increased yam production and food security in Africa.
The document summarizes a seminar on pigeon pea breeding, including its achievements, challenges, and future strategies. It discusses pigeon pea's importance as a nutritional crop and describes traditional breeding approaches that have focused on developing varieties with resistance to biotic and abiotic stresses. Recent developments include identifying genetic markers for disease resistance and developing the first hybrid varieties using genetic male sterility systems, though these hybrids did not widely reach farmers due to high production costs. Moving forward, the document recommends continuing to expand genetic diversity and identify new sources of stress resistance from wild relatives to develop higher yielding pigeon pea varieties.
This document summarizes several methods for creating transgenic plants and animals, including concerns and limitations. It discusses using Agrobacterium-mediated transfection for dicots but needing a gene gun for monocots. It provides examples of transgenic crops including Bt crops and "Golden Rice." It also summarizes creating fluorescent proteins in animals and examples of cloned animals and efforts to preserve endangered species through cloning. The document notes both support and concerns about human cloning.
This document summarizes research on soil microbiology being conducted by IITA. It discusses exploring soil biodiversity in Africa, including identifying new species of arbuscular mycorrhizal fungi. Projects aim to enhance legume productivity through selecting effective rhizobia strains and promoting quality biological products. Research also focuses on controlling striga weed and root-knot nematodes through molecular identification and partnerships. Unconventional approaches explored include exploiting protists for delivery of beneficial microbes, using viral nanoparticles as carriers, and developing transgenic nematode-resistant crops. The document emphasizes the need to intensify African smallholder agriculture through improved soil information and biological solutions.
ICRISAT genebank - Preserving a rich heritage for food securityICRISAT
The ICRISAT genebank conserves genetic resources of crops like sorghum, pearl millet, chickpea and pigeonpea to ensure future food security. It holds over 119,000 accessions from 50+ countries. The collection provides tolerance to stresses and has been characterized for valuable traits. Samples are shared worldwide and maintained by regenerating crops and controlling pollination. ICRISAT also trains scientists and stores duplicates in the Svalbard Global Seed Vault to safeguard against loss.
Genetically modified crops are derived from organisms whose genetic material has been altered through biotechnology. The document discusses the history of genetic engineering and key figures like Paul Berg. It outlines the process for creating GM crops, including identifying a trait of interest and inserting it into a desired organism. Popular GM crops are discussed, like corn, cotton, soybeans, and their traits. Potential risks of GM crops are presented, followed by arguments in their favor that emphasize increased nutrition, yield and reduced environmental impacts. Safety assessments are also described.
The ICRISAT genebank collects over 120,000 germplasm accessions that provide genetic resources for crop improvement programs globally. Over 800 varieties developed from ICRISAT germplasm have been released in 79 countries. Several ICRISAT landraces and accessions have been released as varieties that resulted in economic gains and increased yields. The collection also includes over 2,800 wild relatives of mandate crops that are sources of biotic and abiotic stress resistance traits important for agriculture. Evaluation of mini core collections has identified promising sources for traits such as nutritional quality, drought tolerance, and disease resistance.
The document discusses aflatoxin contamination in Africa and strategies to manage it. Aflatoxins are toxic metabolites produced by the fungus Aspergillus flavus that infect crops like maize and groundnuts. Studies show high levels of aflatoxins in staple crops across Africa, which poses risks to health and trade. Researchers are developing approaches like breeding resistant crop varieties, using atoxigenic biocontrol agents, and integrating management across the value chain to reduce contamination. Regional partnerships are needed to implement solutions and improve food safety.
Genetic modification of plants involves adding a specific stretch of DNA into the plant's genome, giving it new or different characteristics.
INTRODUCTION

The document discusses genetically modified organisms (GMOs) and provides several key facts and figures:
1) Only four countries - the United States, Argentina, Canada, and China - grow almost 90% of the world's GM crops. The vast majority of other countries grow no GMOs.
2) Only four main crops - soy, maize, cotton, and oil-seed rape - make up over 99% of GMOs grown, with herbicide tolerance and insect resistance being the dominant traits.
3) Critics are concerned that genetic engineering may have unintended health and environmental impacts, as it allows for novel genetic combinations not possible through natural breeding.
Golden Rice was created in 1999 to address vitamin A deficiency in rice-dependent populations. Scientists added two genes (psy and crtI) to rice to produce beta-carotene, a precursor to vitamin A. Golden Rice-1 did not produce enough beta-carotene. In 2005, Golden Rice-2 was developed by using a maize psy gene and seed-specific promoter, producing higher beta-carotene levels. Golden Rice is considered safe as beta-carotene is converted to vitamin A only as needed. However, some have raised concerns about allergies, genetic contamination, and impacts on local cultures and biodiversity. Supporters argue it could reduce medical costs and increase productivity compared to alternative
Ann Tutwiler, Director General, Bioversity International presentation on NOT finding the world's next superfood. This presentation was delivered at Kew Gardens on May 12th 2016 at the State of the World's Plants Symposium.
Abstract: In the last few years, superfoods such as quinoa, amaranth and goji berries have been celebrated in the international media in recognition of their rich nutrient content.
But it is not just Western consumers that can benefit from rediscovering these forgotten foods.
M. Ann Tutwiler, Director General, Bioversity International, will explain how many nutritious traditional foods, which have largely fallen off menus and research-for-development agendas in favour of a handful of staple grains, are starting to make a comeback on the plates of the world’s poorest and most malnourished populations.
Bioversity International carries out research on a diverse range of underutilized crops, and advocates for their wider use in healthy diets from sustainable food systems. This overview will include examples of how research-for-development efforts on quinoa in the High Andes and minor millets in India have helped bring diverse varieties back to the farm, the market and the plate. She will highlight how these crops are often not just nutrient-rich but also have a high potential to contribute to livelihoods. They are often also highly resilient to today’s production challenges, such as climate change.
In conclusion, M. Ann Tutwiler will outline the urgent need to identify, promote and protect these useful plants which all have the potential to be placed into a diverse basket of Super Foods when it comes to delivering food and nutrition security.

Introduction: Biotechnology is an emerging field of research as it has the potential to solve many biological problems which could not be solved till now with conventional techniques.
The use of biology to develop technologies and products for the welfare of human beings is known as Biotechnology. It has various applications in different fields such as Therapeutics, Diagnostics, Processed Food, Waste Management, Energy Production, Genetically Modified Crops etc.
Biotechnology means 'applications of scientific and engineering principles to biological processes to provide goods and services'. Full understanding of biological processes is possible with detailed analysis of gene structure and function i.e. the Genetic Engineering means the introduction of manipulated genetic material (DNA) into a cell in such a way as to replicate and be passed on to progeny cells'. The outcome is attractive and promising.

B4FA 2013 Ghana: Introduction to Genetics - Prof Eric Yirenkyi Danquahb4fa
This document provides an overview of basic genetics concepts including:
- Genetics is the study of heredity and variation, focusing on genes which provide instructions for making proteins.
- Gregor Mendel conducted experiments with pea plants in the 1850s and discovered the laws of inheritance, including that traits are passed through discrete units (now known as genes) which segregate and assort independently.
- Cells contain DNA, which carries the genetic code in genes arranged on chromosomes. The order of molecules (A, C, T, G) in the DNA determines an organism's traits.
- Sexual reproduction and random mutation create variation within a population, while genes control the traits passed from parents to
B4FA 2013 Ghana: History of agriculture - Bernie Jonesb4fa
This document provides a history of plant domestication and agriculture. It notes that around 10,000 years ago, early farmers began deliberately selecting crops with desirable traits through a process of natural selection and breeding. Over thousands of years, farmers domesticated crops like wheat, barley, potatoes, goats, sheep, rye, chickens and more in different regions. The document discusses how traditional plant breeding techniques have altered crops over millennia through selection, mutation, and crossing, well before modern genetic engineering. It also addresses the migration and colonization of indigenous African crops versus current staple crops.

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.
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 debris of the ‘last major merger’ is dynamically youngSérgio Sacani
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.
