This paper carries out an analysis of various trade-in programs available for cellphones in the United States. Product trade-in is one of the methods to recover End-of-Life (EoL) products from consumers. Currently, there is a lack of knowledge amongst consumers about such programs. The study aims to determine the factors which influence the product trade-in price. Cell phone trade-in programs of the following types of companies are studied: Phone network operator, online retailer and recycler, and educational institution. Apple’s iPhone was selected to carry out a case study to analyze various features of the trade-in programs. Age of the cell phone model, memory size of the phone, cellphone condition and phone carrier were found to be the most significant factors of a cell phone trade-in program. Newer phone models and higher memory size capacity phones were found to be offered higher price to the consumer. Cellphones of one particular phone carrier and unlocked cell phones were found to obtain the highest price quote. An attempt is made to evaluate and discuss the prospect of trade-in programs as an effective end of life recovery method. Product recovery by trade-in programs and conventional methods is compared based on factors drawn from consumer behavior studies. Improvements in trade-in programs are suggested, followed by a discussion on ways in which data from trade-in programs can benefit product designers.

The United States generates more than 250 million tons of municipal solid waste (trash/garbage), with only 34% being recycled. In the broader global environment, the problem of waste management is becoming increasingly relevant, demanding innovative solutions. Traditional End-of-Life (EOL) approaches to managing waste include recycle, reuse, remanufacture and disposal. Recently, resynthesis was proposed as an alternative to traditional EOL options that combines multiple products to create a new product distinct from its parent assemblies. Resynthesis employs data mining and natural language processing algorithms to quantify assembly/subassembly combinations suitable for new product combinations. However, existing resynthesis methodologies proposed in the design community have been limited to exploring subassembly combinations, failing to explore potential combinations on a materials level. The authors of this paper propose a material resynthesis methodology that combines the materials of multiple EOL products using conventional manufacturing processes that generate candidate resynthesized materials that satisfy the needs of existing domains/applications. Appropriate applications for a resynthesized material are discovered by comparing the properties of the new material to the functional requirements of application classes which are found using clustering and latent semantic analysis. In the course of this paper, the authors present a case study that demonstrates the feasibility of the proposed material resynthesis methodology in the construction materials domain.

AbstractTransmission of the SAR-COV-2 virus that causes COVID-19 is largely driven by human behavior and person-to-person contact. By staying home, people reduce the probability of contacting an infectious individual, becoming infected, and passing on the virus. One of the most promising sources of data on time use is smartphone location data. We develop a time use driven proportional mixing SEIR model that naturally incorporates time spent at home measured using smartphone location data and allows people of different health statuses to behave differently. We simulate epidemics in almost every county in the United States. The model suggests that Americans’ behavioral shifts have reduced cases in 55%-86% of counties and for 71%-91% of the population, depending on modeling assumptions. Resuming pre-epidemic behavior would lead to a rapid rise in cases in most counties. Spatial patterns of bending and flattening the curve are robust to modeling assumptions. Depending on epidemic history, county demographics, and behavior within a county, returning those with acquired immunity (assuming it exists) to regular schedules generally helps reduce cumulative COVID-19 cases. The model robustly identifies which counties would experience the greatest share of case reduction relative to continued distancing behavior. The model occasionally mischaracterizes epidemic patterns in counties tightly connected to larger counties that are experiencing large epidemics. Understanding these patterns is critical for prioritizing testing resources and back-to-work planning for the United States.

Increasing the number of occurrence records available for biodiversity research requires developing efficient pipelines from collectors and observers to data aggregators and then marketing those pipelines to biodiversity researchers. To be effective, these pipelines must recognize that in many countries, internet access is slow, intermittent, or expensive; cell phone internet access may be more common but many people cannot afford the costs associated with using a cell phone for databasing. The pipelines must also make it easy for users to provide high quality data that conforms to international biodiversity data standards. Marketing of these pipelines should include building understanding of these standards and enable data providers to benefit almost immediately from their contributions. Symbiota has succeeded in making over 32 million specimen records available but most come from the United States, a country with fast and reliable internet access in most regions. We have established two Symbiota-based websites, OpenHerbarium and OpenZooMuseum, to enable collectors and collections in Old World countries that lack a national network, to become contributors to and participants in the global biodiversity data sharing community. Talking with biodiversity researchers in such countries has clarified the many impediments to data sharing faced by their collectors and collections. In this presentation, we shall describe the steps we have taken, and are proposing to take, to improve the pipeline for collectors and collections in countries with poor internet access.

Currently, passengers are forbidden from making cell phone calls during flights in the United States due to cellular electronic interference. However, related research has demonstrated that the use of cell phones has little interference with avionics. Furthermore, any potential electronic interference can be eliminated by using new technology. Although talking on the cell phone does not cause electronic interference, the distraction of a passenger caused by a cell phone may negatively impact safety. The purpose of the research was to compare the extent of safety compliance (checking seatbelts, raising tray tables) and retention of announcements among three groups: cell phone conversation, face-to-face conversation (i.e., talking with the passenger next to them), and control. Findings revealed that the cell phone group and the face-to-face group recalled less information from safety announcement and complied with safety behaviors to a lesser degree than the control group. The face-to-face group was not safer than the cell phone group on any measure. Therefore, it is recommended that lifting the ban on in-flight cell phone calls should be considered.

In the United States alone, millions of tons of waste are generated every year, highlighting the urgency for innovative solutions for waste management. Traditional strategies of reducing the amount of End-of-Life (EOL) products include reuse, recycle, remanufacture and disposal. Recently, resynthesis has been proposed in the design community as an alternate approach that aims to combine assemblies/subassemblies of EOL products from multiple domains to create a ‘new’ product, distinct from its parent products. The original work on resynthesis assumes that there is an equal demand for ‘resynthesized products’ based on the available supply of EOL components that the resynthesized products are composed of. Furthermore, the price was assumed to be equal to the price of similar products on the market. However, such an assumption may underestimate or overestimate the value of resynthesized products, which in turn impacts the demand of these products. Recent research has shown that customer reviews express customers’ true opinion and value for specific products or product features. The authors of this paper propose a data mining methodology to quantify the price and demand for resynthesized products by mining user-generated reviews of products publicly available on the internet. A case study involving a resynthesized electronic mouse and white board eraser is presented to demonstrate the feasibility of the proposed methodology.

Abstract Over the past 20 years, there have been many advances in the computer industry as well as in augmentative and alternative communication (AAC) devices. Computers are becoming more compact and have multiple purposes, such as the iPhone, which is a cell phone, mp3 player, and an Internet browser. AAC devices also have evolved to become multi-purpose devices; the most sophisticated devices have functionality similar to the iPhone and iPod. Recently, the idea of having the iPhone and iPad as a communication device was initiated with the development of language applications specifically for this format. It might be true that this idea could become the future of AAC devices; however, there are major access issues to overcome before the idea is a reality. This article will chronicle advancements in AAC devices, specifically on access methods, throughout the years, towards the transition to handheld devices. The newest technologies hold much promise with both features and affordability factors being highly attractive. Yet, these technologies must be made to incorporate alternate access if they are to meet their fullest potential as AAC tools.
