[Slidecast] Modeling the Shared Value of Industry CollaborationSustainable Brands
In this session, John O'Connor, VP Sustainability Research, Gaia Metrics (formerly, World Bank, IMF) suggests a model for applying models typically used to value "own account intangibles" like capitalized R&D and brand equity to industry or shared intangibles, such as pre-competition collaboration and supply chain information systems. Case studies from diverse industries (computers & electronics, pharmaceuticals, textiles & apparel, mining, and alcoholic beverages) will be used to show how shared or industry wide intangibles can play a significant role in shareholder value, in some cases exceeding the contribution of the company's purchased or own account intangibles.
These case studies will be used to propose a tentative typology for how businesses seem to use industry intangibles to maximize shareholder value. Topics for discussion include how businesses seem to use industry intangibles to maximize shareholder value, how examples presented might apply to other industries, and how the value of industry collaboration might be connected to income and expense data, to support return on investment metrics.

This document discusses sustainable food systems. It defines a food system as encompassing all actors and activities involved in food production, processing, distribution, consumption and disposal. A sustainable food system is one that provides food security and nutrition for current and future generations without compromising economic, social or environmental sustainability. It must be economically viable, socially equitable, and have neutral or positive environmental impacts. The food system is driven by biophysical, demographic, technological, political, economic and socio-cultural factors.
The document summarizes Ethiopia's Productive Safety Net Program (PSNP), a large social protection program that aims to smooth food consumption and protect assets for chronically food insecure communities. Key points:
- The PSNP provides direct transfers and public works projects to build community assets like roads and irrigation. It supports up to 8 million beneficiaries with a budget of $0.5 billion annually.
- Independent evaluations show the PSNP improved household food security and dietary diversity but had little impact on child nutrition outcomes. It did not reduce labor supply or crowd out private transfers.
- While the PSNP enhanced resilience, graduation remains a challenge. Targeting in lowland areas also proved difficult. Ensuring timely payments
Some Welfare Consequences of COVID-19 in Ethiopiaessp2
1) The study examines the impacts of COVID-19 on food marketing margins in Ethiopia using phone surveys of farmers, wholesalers, and retailers conducted in February 2020 and May 2020.
2) The surveys found that over 50% of farmers reported receiving less income in May compared to usual times, though most planned to continue vegetable production. Wholesalers reported decreased transport options and client numbers but stable or lower costs, while most retailers saw lower client numbers but stable or lower costs and losses.
3) Retail prices for the main vegetables remained quite stable between February and May, suggesting marketing margins absorbed most impacts of COVID-19 disruptions on vegetable supply chains in Ethiopia during the

The COVID-19 Pandemic and Food Security in Ethiopia – An Interim Analysisessp2
This document summarizes the potential impacts of the COVID-19 pandemic on food security in Ethiopia. It finds that the pandemic is likely to have large short-term negative economic effects through impacts on exports, imports, remittances and domestic lockdown measures. This will reduce GDP, household incomes, employment and agricultural market functioning. Many households are already experiencing income losses, higher food prices and shifts away from nutritious foods. Recommendations include continuing the government's response, addressing misinformation, expanding social safety nets and implementing selective lockdowns.

AFFORDABILITY OF Nutritious foods IN ETHIOPIAessp2
This document summarizes research on the affordability of nutritious diets in Ethiopia. It finds that between 2001 and 2017, the cost of the least expensive diet providing adequate calories and nutrients for an adult woman increased 67% from $0.91 to $1.52. While real prices of some staple foods have decreased in recent years, prices of nutrient-rich foods like dairy, eggs, and meat have increased substantially. However, overall affordability has improved due to rising incomes. Still, ensuring adequate supply of nutritious foods is important to keep their prices low.
The EAT Lancet Publication: Implications for Nutrition Health and Planetessp2
The document discusses a publication by the EAT-Lancet Commission that aimed to define global scientific targets for healthy diets from sustainable food systems. It established a reference diet of 2500 calories per day consisting of vegetables, fruits, whole grains, plant proteins, unsaturated fats, and limited red meat and sugar. Current diets vary widely from this target. The commission also set planetary boundaries related to greenhouse gas emissions, land and water use, and nutrient flows to define a safe operating space for food production. Global modeling was used to identify combinations of measures needed to meet dietary targets sustainably by 2050, such as shifting diets, reducing food waste, and improving agricultural practices.
Sustainable Undernutrition Reduction in Ethiopia (SURE): Evaluation studies essp2
The SURE program is a government-led multisectoral intervention in Ethiopia that aims to reduce undernutrition through a package of interventions like joint household visits, cooking demonstrations, and media campaigns. Evaluation studies of SURE used a quasi-experimental design and found that children's dietary diversity is positively associated with reduced stunting, and that household production of fruits and vegetables was linked to increased child dietary diversity and reduced stunting. However, the studies also found variability in the delivery of nutrition messages across households and limited awareness of nutrition guidelines among local officials.
Policies and Programs on food and Nutrition in Ethiopiaessp2
This document outlines policies and programs on food and nutrition in Ethiopia. It discusses nutrition-specific and nutrition-sensitive interventions, and the pathways through which nutrition-sensitive interventions can affect diet and food systems. It then provides an overview of Ethiopia's policy landscape on food and nutrition, outlining various strategies and policies that aim to improve nutrition, including the Food, Nutrition and Policy, Agriculture Growth Program Phase II, Productive Safety Net Program, and National Nutrition Program. The document concludes that Ethiopia has a favorable policy environment for improving diets and nutrition, but effective implementation, coordination, evidence-based scaling up of interventions, and strong monitoring and evaluation are still needed.
1) Access to nutritious foods is challenging for many households in Ethiopia, especially low-income households, due to high costs and an inability to afford animal-source proteins, zinc, iron, and other micronutrients that are critical for young children's development.
2) A study found that households in Ethiopia spend around 25,000 birr per year on food, with 14,535 birr from purchases and 11,000 birr from own production, but still struggle to meet half of nutritional requirements for children under two.
3) Factors like religious fasting practices and lack of separate feeding plates for children can negatively impact children's diet diversity in Ethiopia. Increased investment in small and
Kaleab Baye presented on diets and stunting in Ethiopia. Stunting rates have declined overall but inequalities persist, with the lowest wealth quintile having the highest rates. Complementary foods in Ethiopia are often low in quantity, diversity, and quality. Improving maternal and child nutrition requires interventions across food systems to increase availability, accessibility, and affordability of nutrient-dense foods as well as improving caregiver feeding practices and maternal health. Comprehensive measures are needed to assess diet quality and reduce consumption of unhealthy foods and risks to food safety.
This document discusses the linkages between irrigation and nutrition in Ethiopia. It notes that Ethiopia's Food and Nutrition Policy and Nutrition Sensitive Agricultural Strategy recognize the role of irrigation in improving nutritional outcomes. There are several pathways through which irrigation can impact nutrition, such as increasing food production, household income, access to water, and women's empowerment. Studies show that children and women in irrigating households in Ethiopia have better dietary diversity and nutrient intake, as well as reduced stunting and wasting, compared to non-irrigating households. Therefore, promoting irrigation can help improve nutrition in addition to increasing income and agricultural yields.

Essentials of Automations: Exploring Attributes & Automation ParametersSafe Software
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

Bram Verhoef, Head of Machine Learning at Axelera AI, presents the “How Axelera AI Uses Digital Compute-in-memory to Deliver Fast and Energy-efficient Computer Vision” tutorial at the May 2024 Embedded Vision Summit.
As artificial intelligence inference transitions from cloud environments to edge locations, computer vision applications achieve heightened responsiveness, reliability and privacy. This migration, however, introduces the challenge of operating within the stringent confines of resource constraints typical at the edge, including small form factors, low energy budgets and diminished memory and computational capacities. Axelera AI addresses these challenges through an innovative approach of performing digital computations within memory itself. This technique facilitates the realization of high-performance, energy-efficient and cost-effective computer vision capabilities at the thin and thick edge, extending the frontier of what is achievable with current technologies.
In this presentation, Verhoef unveils his company’s pioneering chip technology and demonstrates its capacity to deliver exceptional frames-per-second performance across a range of standard computer vision networks typical of applications in security, surveillance and the industrial sector. This shows that advanced computer vision can be accessible and efficient, even at the very edge of our technological ecosystem.

Digital Banking in the Cloud: How Citizens Bank Unlocked Their MainframePrecisely
Inconsistent user experience and siloed data, high costs, and changing customer expectations – Citizens Bank was experiencing these challenges while it was attempting to deliver a superior digital banking experience for its clients. Its core banking applications run on the mainframe and Citizens was using legacy utilities to get the critical mainframe data to feed customer-facing channels, like call centers, web, and mobile. Ultimately, this led to higher operating costs (MIPS), delayed response times, and longer time to market.
Ever-changing customer expectations demand more modern digital experiences, and the bank needed to find a solution that could provide real-time data to its customer channels with low latency and operating costs. Join this session to learn how Citizens is leveraging Precisely to replicate mainframe data to its customer channels and deliver on their “modern digital bank” experiences.
Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

Lambda, Elastic Beanstalk, Lightsail, Amplify, S3 (and more!) can each host websites + APIs. But which one should we choose?
Which one is cheapest? Which one is fastest? Which one will scale to meet our needs?
Join me in this session as we dive into each AWS hosting service to determine which one is best for your scenario and explain why!
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?
