The Impact

Many engineering departments often struggle with meeting “the broad education necessary to understand the impact of engineering solutions in a global, economic, environmental, and societal context” (outcome h) that is required by ABET. The already packed curricula provide few opportunities to offer meaningful experiences to address this outcome, and most departments relegate this requirement to an early cornerstone or later capstone design experience as a result, making these courses an ineffective “catch all” for many ABET requirements. We address this issue by using the paradigm of product archaeology, defined as the process of reconstructing the lifecycle of a product — the customer requirements, design specifications, and manufacturing processes used to produce it — to understand the decisions that led to its development. By considering products as designed artifacts with a history rooted in their development, we embed context as a central component in developing design solutions. Specifically, in our work we have implemented several approaches to integrate contextual thinking into a senior level engineering design course. Following Kolb’s model of experiential learning and an instructional framework adapted for product archaeology (inclusive of evaluate-explain-prepare-excavate activities) we have restructured the course to embed specific and targeted reflection, dissection, and analysis activities so that students teams effectively address the global, economic, environmental, and societal factors in their design solutions. This paper provides the theoretical framework of our instructional approach, describes the specific instructional activities we implemented, and results from our pre and post survey assessments that describe the impact on students’ understanding of contextual as well engineering design topics.

Many decisions within engineering systems design are typically made by humans. These decisions significantly affect the design outcomes and the resources used within design processes. While decision theory is increasingly being used from a normative standpoint to develop computational methods for engineering design, there is still a significant gap in our understanding of how humans make decisions within the design process. Particularly, there is lack of knowledge about how an individual's domain knowledge and framing of the design problem affect information acquisition decisions. To address this gap, the objective of this paper is to quantify the impact of a designer's domain knowledge and problem framing on their information acquisition decisions and the corresponding design outcomes. The objective is achieved by (i) developing a descriptive model of information acquisition decisions, based on an optimal one-step look ahead sequential strategy, utilizing expected improvement maximization, and (ii) using the model in conjunction with a controlled behavioral experiment. The domain knowledge of an individual is measured in the experiment using a concept inventory, whereas the problem framing is controlled as a treatment variable in the experiment. A design optimization problem is framed in two different ways: a domain-specific track design problem and a domain-independent function optimization problem (FOP). The results indicate that when the problem is framed as a domain-specific design task, the design solutions are better and individuals have a better state of knowledge about the problem, as compared to the domain-independent task. The design solutions are found to be better when individuals have a higher knowledge of the domain and they follow the modeled strategy closely.

The Impact

Many engineering departments struggle to meet “the broad education necessary to understand the impact of engineering solutions in a global, economic, environmental, and societal context” (Outcome h) that is required for ABET. As a result, engineering students receive meaningful contextual experiences in piecemeal fashion and graduate with a lack of concrete competencies that bridge knowledge and practice in the global world in which they will live and work. By considering products as designed artifacts with a history rooted in their development, our product archaeology framework combines concepts from archaeology with advances in cyber-enhanced product dissection to implement pedagogical innovations that address the significant educational gap. In this paper, we focus on assessing elements of a sustainable and scalable foundation that can support novel approaches aimed at educating engineering students to understand the global, economic, environmental, and societal context and impact of engineering solutions. This foundation is being developed across a network of partner institutions. We present recent results from freshman, sophomore, and senior courses at two of the partners in the national network of institutions.

The study aimed to describe views on Voluntary Assisted Dying (VAD), gleaned through qualitative analysis of participant responses to a set activity, run during the 2018 ‘Dying2Learn’ Massive Open Online Course (MOOC). Data from 508 participants, most of whom identified as health professionals, were analysed using thematic content analysis, and themes generated. A large proportion of participants discussed their personal views related to VAD, specifically around choice, control, dignity, palliative care and dying at home, medical intervention, societal factors, the impact on those left behind, laws and regulations, dying ‘naturally’, advance care directives, and being in pain. In this study, participants had many different views on the act itself, often divisive, but also with common concepts such as respecting the choices and decisions of others.

Environmental Microbes

Environmental heterogeneity is a central component influencing the virulence and epidemiology of infectious diseases. The number and distribution of susceptible hosts determines disease transmission opportunities, shifting the epidemiological threshold between the spread and fadeout of a disease. Similarly, the presence and diversity of other hosts, pathogens and environmental microbes, may inhibit or accelerate an epidemic. This has important applied implications in farming environments, where high numbers of susceptible hosts are maintained in conditions of minimal environmental heterogeneity. We investigated how the quantity and quality of aquaculture enrichments (few vs. many stones; clean stones vs. stones conditioned in lake water) influenced the severity of infection of a pathogenic bacterium, Flavobacterium columnare, in salmonid fishes. We found that the conditioning of the stones significantly increased host survival in rearing tanks with few stones. A similar effect of increased host survival was also observed with a higher number of unconditioned stones. These results suggest that a simple increase in the heterogeneity of aquaculture environment can significantly reduce the impact of diseases, most likely operating through a reduction in pathogen transmission (stone quantity) and the formation of beneficial microbial communities (stone quality). This supports enriched rearing as an ecological and economic way to prevent bacterial infections with the minimal use of antimicrobials.

The Impact

During the first wave of the coronavirus disease 2019 (COVID-19) pandemic, the lockdown enforced led to considerable disruption to the activities of dental services, even leading to closures. To mitigate the impact of the lockdowns, systems were quickly put in place in most countries to respond to dental emergencies, giving priority to distance screening, advice to patients by remote means, and treatment of urgent cases while ensuring continuous care. Digital health was widely adopted as a central component of this new approach, leading to new practices and tools, which in turn demonstrated its potential, limitations, and possible excesses. Political leaders must become aware of the universal availability of digital technology and make use of it as an additional, safe means of providing services to the public. In view of the multiple uses of digital technologies in health—health literacy, teaching, prevention, early detection, therapeutics, and public health policies—deployment of a comprehensive program of digital oral health will require the adoption of a multifaceted approach. Digital tools should be designed to reduce, not increase, inequalities in access to health care. It offers an opportunity to improve healthy behavior, lower risk factors common to oral diseases and others noncommunicable diseases, and contribute to reducing oral health inequalities. It can accelerate the implementation of universal health coverage and help achieve the 2030 Sustainable Development Agenda, leaving no one behind. Digital oral health should be one of the pillars of oral health care after COVID-19. Universal access to digital oral health should be promoted globally. The World Health Organization’s mOralHealth program aims to do that. Knowledge Transfer Statement: This position paper could be used by oral health stakeholders to convince their government to implement digital oral health program.

Aims and objectives: This paper is a report of a study of experiences of people with Cystic Fibrosis (CF) with their hospital admission. It evaluates how they perceive their treatment and care and the impact on their social life (school or work). Background: In The Netherlands, people with CF are hospitalized in seven CF centers. In general, hospitalization may raise several challenges concerning the patient’s psychosocial well-being, before, during and after the admission. The admission of people with CF is complicated, because of segregated treatment and care that aims to prevent hospital-based cross-infection. Design: This article reports on a qualitative study. Methods: Data were collected during 2009 and 2010. Nineteen people with CF admitted for more than 5 days in one of the seven Dutch CF-centres participated. Results and conclusions: The findings are organized into five contexts with subthemes: Before admission & Arrival (1); Treatment & Care (2); Room & Stay (3); Discharge (4); Social & Societal context (5). The findings show that patients express a need for enhancing the quality of some treatments, like intravenous injections and patients express normative expectations of professionals that directly relate to their psychosocial well-being, e.g. they want to be ‘seen’ and treated as human beings and not solely as patients. They desire segregation policies to be consistent, whilst simultaneously they prefer flexible segregation guidelines. In general, respondents are satisfied with hospital facilities. The study reports on challenges concerning continuation of school and work during the admission. The paper is relevant to every hospital where people are being nursed in isolation.

Clustering Approach

Faithfully obtaining design specifications from customer requirements is essential for successful designs. The natural lingual, inexact, incomplete and vague attributes of customer requirements make it very difficult to map customer requirements to design specifications. In general design process, the design specifications are determined by designers based on their experience and intuition, and often a certain target value is set for a specification. However, it is on one hand very difficult, on the other hand unreasonable, so a suitable limit range rather than a certain value is preferred at the beginning of design, especially at the concept design process. In this paper, a simplified systematic approach of transforming customer requirements to design specifications is proposed. First, a two-stepped clustering approach for grouping customer requirements and design specifications based on HOQ matrix is presented, by which the mapping is limited to within each group. To further simplify the inference mapping rules of customer requirements and design specifications, the minimal condition inference mapping rules for each design specification are extracted based on rough set theory. In the end, a suitable value range is determined for a specification by applying the fuzzy rule matrix.

The Impact

During the current COVID-19 pandemic, governments must make decisions based on a variety of information including estimations of infection spread, health care capacity, economic and psychosocial considerations. The disparate validity of current short-term forecasts of these factors is a major challenge to governments. By causally linking an established epidemiological spread model with dynamically evolving psychosocial variables, using Bayesian inference we estimate the strength and direction of these interactions for German and Danish data of disease spread, human mobility, and psychosocial factors based on the serial cross-sectional COVID-19 Snapshot Monitoring (COSMO; N = 16,981). We demonstrate that the strength of cumulative influence of psychosocial variables on infection rates is of a similar magnitude as the influence of physical distancing. We further show that the efficacy of political interventions to contain the disease strongly depends on societal diversity, in particular group-specific sensitivity to affective risk perception. As a consequence, the model may assist in quantifying the effect and timing of interventions, forecasting future scenarios, and differentiating the impact on diverse groups as a function of their societal organization. Importantly, the careful handling of societal factors, including support to the more vulnerable groups, adds another direct instrument to the battery of political interventions fighting epidemic spread.
