Learning and teaching notes:

This case involves Aziza, a biomedical engineer working for Neuraltrix, a hypothetical company that develops Brain-computer interfaces (BCI) for specialised applications. Aziza has always been curious about the brain and enthusiastic about using cutting-edge technologies to help people in their daily lives. Her team has designed a BCI that can measure brain activity non-invasively and, by applying machine learning algorithms, assess the job-related proficiency and expertise level of a person. She is leading the deployment of the new system in hospitals and medical schools, to be used in evaluating candidates being considered for consultant positions. In doing so, and to respond to requests to extend and use the BCI-based system in unforeseen ways, she finds herself compelled to weigh various ethical, legal and professional responsibilities.

This case study addresses two of AHEP 4’s themes: The Engineer and Society (acknowledging that engineering activity can have a significant societal impact) and Engineering Practice (the practical application of engineering concepts, tools and professional skills). To map this case study to AHEP outcomes specific to a programme under these themes, access AHEP 4 here and navigate to pages 30-31 and 35-37.

The dilemma in this case is presented in three parts. If desired, a teacher can use the Summary and Part one in isolation, but Parts two and three develop and complicate the concepts presented in the Summary and Part one to provide for additional learning. The case allows teachers the option to stop at multiple points for questions and/or activities as desired.

Summary:

Brain-computer interfaces (BCIs) detect brain activity and utilise advanced signal analysis to identify features in the data that may be relevant to specific applications. These features might provide information about people’s thoughts and intentions or about their psychological traits or potential disorders, and may be interpreted for various purposes such as for medical diagnosis, for providing real-time feedback, or for interacting with external devices such as a computer. Some current non-invasive BCIs employ unobtrusive electroencephalography headsets or even optical (near-infrared) sensors to detect brain function and can be safe and convenient to use.

Evidence shows that the brains of people with specialised expertise have identifiable functional characteristics. Biomedical technology may translate this knowledge soon into BCIs that can be used for objectively assessing professional skills. Researchers already know that neural signals support features linked to levels of expertise, which may enable the assessment of job applicants or candidates for promotion or certification.

BCI technology would potentially benefit people by improving the match between people and their jobs, and allowing better and more nuanced career support. However, the BCI has access to additional information that may be sensitive or even troubling. For example, it could reveal a person’s health status (such as epilepsy or stroke), or it may suggest psychological traits ranging from unconscious racial bias to psychopathy. Someone sensitive about their privacy may be reluctant to consent to wearing a BCI.

In everyday life, we show what is on our minds through language and behaviour, which are normally under our control, and provide a buffer of privacy. BCIs with direct access to the brain and increasing capability to decode its activity may breach this buffer. Information collected by BCIs could be of interest not only to employers who will decide whether to hire and invest in a new employee, but also to health insurers, advertising agencies, or governments.

 

Optional STOP for questions and activities:

1. Activity: Risks of brain activity decoding – Identify the physical, ethical, and social difficulties that could result from the use of devices that have the ability to directly access the brain and decipher some of its psychological content such as thoughts, beliefs, and emotions.

2. Activity: Regulatory oversight – Investigate which organisations and regulatory bodies currently monitor and are responsible for the safe and ethical use of BCIs.

3. Activity: Technical integration – Investigate how BCIs work to translate brain activity into interpretable data.

 

Dilemma – Part one:

After the company, Neuraltrix, deployed their BCI and it had been in use for a year in several hospitals, its lead developer Aziza became part of the customer support team. While remaining proud and supportive of the technology, she had misgivings about some of its unexpected ramifications. She received the following requests from people and institutions for system modifications or for data sharing:

1. A hospital asked Neuraltrix for a technical modification that would allow the HR department to send data to their clinical neurophysiologists for “further analysis,” claiming that this might benefit people by potentially revealing a medical abnormality that might otherwise be missed.

2. An Artificial Intelligence research group partnering with Neuraltrix requested access to the data to improve their signal analysis algorithms.

3. A private health insurance company requested Neuraltrix provide access to the scan of someone who had applied for insurance coverage; they stated that they have a right to examine the scan just as life insurance agencies are allowed to perform health checks on potential customers.

4. An advertising agency asked Neuraltrix for access to their data to use them to fine-tune their customer behavioural prediction algorithms.

5. A government agency demanded access to the data to investigate a suspected case of “radicalisation”.

6. A prosecutor asked for access to the scan of a specific person because she had recently been the defendant in an assault case, where the prosecutor is gathering evidence of potential aggressive tendencies.

7. A defence attorney requested data because they were gathering potentially exonerating evidence, to prove that the defendant’s autonomy had been compromised by their brain states, following a line of argument known as “My brain made me do it.”

 

Optional STOP for questions and activities: 

1. Activity: Identify legal issues – Students could research what laws or regulations apply to each case and consider various ways in which Neuraltrix could lawfully meet some of the above requests while rejecting others, and how their responses should be communicated within the company and to the requestor.

2. Activity: Identify ethical issues – Students could reflect on what might be the immediate ethical concerns related to sharing the data as requested.

3. Activity: Discussion or Reflection – Possible prompts:

 

Dilemma – Part two:

The Neuraltrix BCI has an interface which allows users to provide informed consent before being scanned. The biomedical engineer developing the system was informed about a customer complaint which stated that the user had felt pressured to provide consent as the scan was part of a job interview. The complaint also stated that the user had not been aware of the extent of information gleaned from their brains, and that they would not have provided consent had been made aware of it.

 

Optional STOP for questions and activities: 

1. Activity: Technical analysis – Students might try to determine if it is possible to design the BCI consent system and/or consent process to eliminate the difficulties cited in the complaint. Could the device be designed to automatically detect sensitive psychological content or allow the subject to stop the scan or retroactively erase the recording?

2. Activity: Determine the broader societal impact and the wider ethical context – Students should consider what issues are raised by the widespread availability of brain scans. This could be done in small groups or a larger classroom discussion.

Possible prompts:

 

Dilemma – Part three:

Neuraltrix BCI is about to launch its updated version, which features all data processing and storage moved to the cloud to facilitate interactive and mobile applications. This upgrade attracted investors and a major deal is about to be signed. The board is requesting a fast deployment from the management team and Aziza faces pressure from her managers to run final security checks and go live with the cloud version. During these checks, Aziza discovers a critical security issue which can be exploited once the BCI runs in the cloud, risking breaches in the database and algorithm. Managers believe this can be fixed after launch and request the engineer to start deployment and identify subsequent solutions to fix the security issue.

 

Optional STOP for questions and activities: 

1. Activity: Students should consider if it is advisable for Aziza to follow requests from managers and the Neuraltrix BCI board and discuss possible consequences, or halt the new version deployment which may put at risk the new investment deal and possibly the future of the company.

2. Activity: Apply an analysis based on “Duty-Ethics” and “Rights Ethics.” This could be done in small groups (who would argue for management position and engineer position, respectively) or a larger classroom discussion. A tabulation approach with detailed pros and cons is recommended.

3. Activity: Apply a similar analysis as above based on the principles of “Act-Utilitarianism” and “Rule-Utilitarianism.”

Learning and teaching notes:

This case involves an engineer responsible for verifying the source of recycled construction material to ensure it is not contaminated. The case is presented in three parts. Part one focuses on the environmental, professional, and social contexts and may be used in isolation to allow students to explore both micro-ethical and macro-ethical concerns. Parts two and three bring in a dilemma about public information and communication and allows students to consider their positions and potential responses. The case allows teachers the option to stop at multiple points for questions and / or activities as desired.

This case study addresses two of AHEP 4’s themes: The Engineer and Society (acknowledging that engineering activity can have a significant societal impact) and Engineering Practice (the practical application of engineering concepts, tools and professional skills).

Dilemma – Part one:

Charlie is a junior environmental engineer who started working at Circle Mat after graduating. Circle Mat is a construction products company that takes pride in using recycled materials from waste in their products, such as mortars and concretes. In fact, Circle Mat was recently nominated by the National Sustainability Association in the prize for the most innovative and sustainable production chains.

Charlie’s role is to ensure that the quality standards of the recycled waste used in the products are met. She is sent a report every two weeks from the factories receiving the waste and she checks the properties of this waste. While she is also supposed to visit all the factories once a month, her direct supervisor, Sam, advised her to visit only those factories where data shows that there are problems with the quality. While it is Charlie’s responsibility to verify the quality and to create the factory visit plan, she trusts her line manager as to how best approach her work.

Among all the factories with which they are working, the factory in Barretton has always had the highest quality standards, and since it is very far from where Charlie is based, she has postponed for months her visit to that factory.

 

Optional STOP for questions and activities:

1. Discussion: Charlie is responsible for checking the quality from the data she receives, but what about the quality/reliability of the data? Where does her responsibility begin and end? What ethical guidance, codes, or frameworks can help her decide?

2. Activity: Research the issue of asbestos, including current science, potential risks, and legal implications.

3. Discussion: Macroethical context – What is circularity, and how does it relate to climate goals or environmental practice?

  

Dilemma: Part two:

After several months, she finally goes to the town where the factory is located. Before getting to the factory, she stops for a coffee at the town’s café. There, she enquires of the waiter about the impacts of the factory on the town. The waiter expresses his satisfaction and explains that since Circle Mat started operations there, the town has become much more prosperous.

When Charlie reaches the factory, she notices a pile of waste that, she assumes, is the one that is being used as recycled aggregate in concrete. Having a closer look, she sees that it is waste from demolition of a building, with some insulation walls, concrete slabs and old pipes. At that moment, the head of the factory arrives and kindly shows Charlie around.

At the end of the visit, Charlie asks about the pile, and the head says that it is indeed demolition waste from an old industrial building. By the description, Charlie remembers that there are some buildings in the region that still contain asbestos, so asks whether the demolition material could potentially have asbestos. To Charlie’s surprise, the head reacts aggressively and says that the visit is over.

 

Optional STOP for questions and activities:

1. Activity: Use an environmental and social Life Cycle Assessment tool to assess the environmental and social impacts that the decision that Charlie makes might have.

2. Discussion: Map possible courses of action regarding the approach that Charlie could adopt when the factory head tries to shut down the visit. Discuss which is the best approach and why. Some starting questions would be: What should Charlie do? What feels wrong about this situation?

3. Discussion: if she reports her suspicions to her manager, what data or evidence can she present? Should she say anything at all at this point?

 

Dilemma – Part three:

In the end, Charlie decides not to mention anything, and after writing her report she leaves Barretton. A few days later, Circle Mat is announced to be the winner of the prize by the National Sustainability Association. Circle Mat organises a celebration event to be carried out in Barretton. During the event, Charlie discovers that Circle Mat’s CEO is a relative of the mayor of Barretton.

She is not sure if there really is asbestos in the waste, and also she does not know if other factories might be behaving in the same way. Nonetheless, other junior engineers are responsible for the other factories, so she doesn’t have access to the information.

Some days after the event, she receives a call from a journalist who says that they have discovered that the company is using waste from buildings that contain asbestos. The journalist is preparing an article to uncover the secret and wants to interview her. They ensure that, if she wants, her identity will be kept anonymous. They also mention that, if she refuses to participate, they will collect information from other sources in the company.

 

Optional STOP for questions and activities:

1. Activity: Technical integration related to measuring contaminants in waste products used for construction materials.

2. Discussion: What ethical issues can be identified in this scenario? Check how ethical principles of the construction sector inform the ethical issues that may be present, and the solutions that might be possible.

3. Discussion: What interpersonal and workplace dynamics might affect the approach taken to resolve this situation? 

4. Discussion: Would you and could you take the interview with the journalist? Should Charlie? Why or why not?

5. Activity: In the case of deciding to take the interview, prepare the notes you would take to the interview.

Learning and teaching notes: 

This case study puts students in the shoes of an engineer who is required to select a subcontractor to manufacture systems and parts. There are stipulations around who can be selected, among which are legal and ethical concerns around  suspicions of slavery or forced labour. The engineer must navigate communication with both their supervisors and their potential subcontractor, and ultimately justify their decision.  

This case study addresses two of the themes from the Accreditation of Higher Education Programmes fourth edition (AHEP4): The Engineer and Society (acknowledging that engineering activity can have a significant societal impact) and Engineering Practice (the practical application of engineering concepts, tools and professional skills).

Summary: 

Autonomous Vehicle Corporation (AVC) has recently been awarded a contract to provide a bespoke design unmanned air vehicle to India. AVC is a UK certified B Corp that prides itself on maintaining the highest standards of social and environmental performance, transparency, and accountability. 

A stipulation of the newly awarded contract is that at least 30% of the contract value is spent on the manufacture of sub-systems and parts from subcontractors based in India. AVC is responsible for identifying and contracting these suppliers. 

After many years working as a Systems Engineer for AVC, you have been selected as the Lead Engineer for the project, responsible for the selection of the Indian suppliers. You are aware from your initial research of reports regarding slave and forced labour in the region’s manufacturing industry and are concerned that this situation might affect the project and the company. Additionally, you would personally feel uncomfortable knowing that you might contract a supplier who engaged in those practices. 

 

Optional STOP for questions and activities: 

1. Activity: To consider how AVC might be impacted from engaging a supplier that utilises slave or forced labour, chart out the viewpoints of different stakeholders, such as customers, investors, other suppliers, communities, and employees. 

2. Discussion: Are there other factors besides ethical considerations that may influence your selection of supplier? What are these?  

3. Discussion: How would you weigh the importance of ethical considerations, such as the use of slave or forced labour, against the other factors identified in the previous question? What information or resources might you use in guiding your weighting of these considerations? 

4. Activity: Contrast the UK Engineering Council’s code of ethics with the Engineering Council of India’s Code of Ethics. How do the two differ? Which code should you be primarily guided by in this situation? Why? How might cultural expectations and norms influence what is seen as ethical?  

 

Dilemma – Part one: 

One supplier you are considering is Quality Electronics Manufacturing Pvt. Ltd. (QEM), a company based outside Naya Raipur in one of India’s poorest provinces. During a video call, QEM’s managing director assures you that they comply with a strict code of ethics and conduct all recruitment through a carefully selected list of brokers and agencies. He tells you that QEM sources raw materials from around the world, and none of their suppliers have ever been convicted of any offences relating to slavery. He invites you to tour their factory when you are in the country next month and will personally escort you to answer any questions you may have. 

 

Optional STOP for questions and activities: 

1. Activity: Does anything you have heard give you cause for concern regarding the risk of slave or forced labour at QEM in particular? Research this issue from the perspective of various sources, such as investigative journalism, academic papers, government reports, and industry publications. Do their conclusions align or differ in any significant ways? Are there any gaps in knowledge that these sources haven’t adequately covered?  

2. Discussion: QEM mentions that they source raw materials from around the world. The reality of modern supply chains is that they often involve multiple complex layers of subcontractors. Does AVC have an ethical duty to consider the whole supply chain? Would this be the same if AVC were further down the supply chain? If AVC were further down the supply chain, would they have to consider the upstream elements of the supply chain? What are the business implications of considering an entire supply chain? 

3. Activity: List possible contextual risk factors and potential indicators of slave and forced labour. Which are present in the case of QEM? 

4. Activity and discussion: Create a set of questions you wish to answer during your visit to QEM to help assess the risk that they are engaged in the use of slave or forced labour. How will you get this information? Who will you need to talk to? What evidence would you expect to see and collect? To practise business communication, students could draft a memo to their supervisor explaining the situation and outlining their proposed course of action.  

 

Dilemma – Part two: 

During your visit to QEM’s factory, you meet with workers at all levels and you review QEM’s policies and procedures. You identify some potential risk factors that could indicate QEM is using forced labour in its workforce. You raise this with QEM’s managing director, but he responds indignantly, “QEM creates good jobs for our workers and without us they would not be able to feed their families. Your contract would allow us to sustain those jobs and create many more for the local community.” 

You know that QEM is the lowest cost supplier for the work you want them to undertake, and you are under pressure to keep budgets down. You have no conclusive evidence that QEM uses forced labour. You also know that the alternative suppliers you could use are all based in regions with high employment, which means the risk of not being able to staff your work (resulting in schedule delays) is high.  

Upon your return to the UK, your project manager calls you into her office and tells you she needs your decision on whether to utilise QEM by the end of the week. 

 

Optional STOP for questions and activities: 

1. Activity: Conduct a risk analysis that identifies what might be the impact of not using QEM and what might be the impact of using QEM. 

2. Debate: Do you use QEM as one of your suppliers? Why, or why not? You may wish to consider your answer using the lens of uncertainty and risk. 

3. Discussion: What actions could you put in place with QEM to reduce the incidence/risk of slave or forced labour in its workforce? Which of these would you recommend, and which would you require, QEM to implement as part of contracting with them? How would you enforce them, and what evidence of them being successfully implemented would you need? 

 

Dilemma – Part three – Postscript:

If you chose to use QEM: It is now two years after you subcontracted QEM. An investigation by an NGO has uncovered the rampant use of slave and forced labour within the global electronics manufacturing industry by companies with B-Corp status. AVC is named as one of the perpetrators, and a story about workers at QEM is scheduled to run in a leading tabloid newspaper tomorrow morning. AVC has called an emergency press conference to give its side of the story.  

If you chose not to use QEM: The following week, your project manager calls you into her office again. She tells you that she has just stepped out of a meeting with the board, and they are deeply concerned about spiralling costs on your project. In particular, they are concerned that you rejected QEM’s proposal in favour of another supplier who is more than twice as expensive. You have been asked to present your reasoning to the board when they reconvene shortly.  

 

Optional STOP for activity:

1. Roleplay either the press conference or the board meeting and defend your decision.

Summary: 

Kelechi is a civil engineer in a stable job, working on the infrastructure team of a County Council that focuses on regeneration and public realm improvements. Kelechi grew up in an environment where climate change and its real impacts on people was discussed frequently. She was raised with the belief that she should live as ethically as possible, and encourage others to consider their impact on the world. These beliefs were instrumental in leading Kelechi into a career as a civil engineer, in the hope that she could use her skills and training to create a better world. In one of her engineering modules at university, Kelechi met Amanda, who encouraged her to join a student group pushing for sustainability within education and the workplace. Kelechi has had some success with this within her own job, as her employer has been willing to participate in ongoing discussions on carbon and resilience, and is open to implementing creative solutions.  

But Kelechi is becoming frustrated at the lack of larger scale change in the wake of the climate emergency. Over the years she has signed petitions and written to her representatives, then watched in dismay as each campaign failed to deliver real world carbon reduction, and as the government continued to issue new licenses for fossil fuel projects. Even her own employers have failed to engage with climate advocates pushing for further changes in local policy, changes that Kelechi believes are both achievable and necessary. Kelechi wonders what else she can do to set the UK – if not the world – on a path to net zero. 

 

Dilemma – Part one: 

Scrolling through a news website, Kelechi is surprised to see a photo of her friend and ex-colleague Amanda, in a report about climate protesters being arrested. Kelechi messages Amanda to check that she’s ok, and they get into a conversation about the protests. Amanda is part of a climate protest group of STEM professionals that engages in non-violent civil disobedience. The group believes that by staging direct action protests they can raise awareness of the climate emergency and ultimately effect systemic change.  

Amanda tries to convince Kelechi to join the group and protest with them. Amanda references the second principle of the Statement of Ethical Principles published by the Engineering Council and the Royal Academy of Engineering: “Respect for life, law, the environment and public good.” Amanda believes that it is ok to ignore the tenet about respect for the law in an effort to safeguard the other three, and says that there have been plenty of unjust laws throughout history that have needed to be protested in order for them to be changed for the public good. She also references another part of the Statement: that engineers should ”maximise the public good and minimise both actual and potential adverse effects for their own and succeeding generations”. Amanda believes that by protesting she is actually fulfilling her duty to uphold these principles.  

Kelechi isn’t sure. She has never knowingly broken the law before, and is worried about being arrested. Kelechi consults her friend Max, who is a director of a professional engineering institution, of which Kelechi is a member. Max, whilst she has some sympathies for the aims of the group, immediately warns Kelechi away from the protests. “Forget about being arrested; you could lose your job and end your career.”  

 

Optional STOP for questions and activities: 

1. Discussion: What personal values will Kelechi have to weigh in order to decide whether or not to take part in a civil disobedience protest? 

2. Discussion: Consider the tenet of the Statement of Ethical Principles “Respect for life, law, the environment and public good.” To what extent (if at all) do the four tenets of this ethical principle come into conflict with one another in this situation? Can you think of other professional situations in which they might conflict? 

3. Discussion: Is breaking the law always unethical? Are there circumstances when breaking the law might be the ethical thing to do in the context of engineering practice? What might these circumstances be? 

4. Discussion: To what extent (if at all) does the content of the Statement of Ethical Principles make a case for or against being part of a protest where the law is broken?  

5. Discussion: Following on from the previous question – does it make a difference what is being protested, if a law is broken? For example, is protesting fossil fuels that lead to climate change different from protesting unsafe but legal building practices, such as cladding that causes a fire risk? Why? 

6. Activity: Research other professional codes of engineering: do these have clear guidelines for this situation? Assemble a bibliography of other professional codes or standards that might be relevant to this scenario. 

7. Discussion: What are the potential personal and professional risks or benefits for Kelechi if she takes part in a protest where the law is broken? 

8. Discussion: From a professional viewpoint, should Kelechi take part in the protest? What about from a personal viewpoint? 

 

Dilemma – Part two: 

After much deliberation, Kelechi decides to join the STEM protest group. Her first protest is part of a direct action to blockade a busy London bridge. To her own surprise, she finds herself volunteering to be one of two protesters who will climb the cables of the bridge. She is reassured by the risk assessment undertaken by the group before selecting her. She has climbing experience (although only from her local leisure centre), and safety equipment is provided.  

On the day of the protest, Kelechi scales the bridge. The police are called and the press arrive. Kelechi stays suspended from the bridge for 36 hours, during which time all traffic waiting to cross the bridge is halted or diverted. Eventually, Kelechi is convinced that she should climb down, and the police arrest all of the protesters.  

Later on, Kelechi is contacted by members of the press, asking for a statement about her reason for taking part in the protest. Kelechi has seen that press coverage of the protest is so far overwhelmingly negative, and poll results suggest that the majority of the public see the protesters’ actions as selfish, inconvenient, and potentially dangerous, although some have sympathy for their cause. “What if someone died because an ambulance couldn’t use the bridge?” asks someone via social media. “What about the five million deaths a year already caused by climate change?” asks another, citing a recent news article.  

Kelechi would like to take the opportunity to make her voice heard – after all, that’s why she joined the protest group – but she isn’t sure whether she should mention her profession. Would it add credibility to her views? Or would she be lambasted because of it? 

 

Optional STOP for questions and activities: 

1. Discussion: What professional principles or codes is Kelechi breaking or upholding by scaling the bridge?  

2. Activity: Compare the professional and ethical codes for civil engineers in the UK and elsewhere. How might they differ in their guidance for an engineer in this situation?  

3. Activity: Conduct a risk assessment for a) the protesters who have chosen to be part of this scenario, and b) members of the public who are incidentally part of this scenario. 

4. Discussion: Who would be responsible if, as a direct or indirect result of the protesters blocking the bridge, a) a member of the public died, or b) a protester died? Who is responsible for the excess deaths caused directly or indirectly by climate change? 

5. Discussion: How can Kelechi best convey to the press and public the quantitative difference between the short-term disruption caused by protests and the long-term disruption caused by climate change? 

6. Discussion: Should Kelechi give a statement to the press? If so, should she discuss her profession? What would you do in her situation? 

7. Activity: Write a statement for Kelechi to release to the press. 

8. Discussion: Suggest alternative ways of protesting that would have as much impact in the news but potentially cause less disruption to the public. 

 

Dilemma – Part three: 

Kelechi decides to speak to the press. She talks about the STEM protest group, and she specifically cites the Statement of Ethical Principles as her reason for taking part in the protest: “As a professional civil engineer, I have committed to acting within our code of ethics, which requires that I have respect for life, the environment and public good. I will not just watch lives be destroyed if I can make a difference with my actions.”  

Whilst her statement gets lots of press coverage, Kelechi is called out by the media and the public because of her profession. The professional engineering institution of which Kelechi is a member receives several complaints about her actions, some from members of the public and some from other members of the institution. “She’s bringing the civil engineering profession into disrepute,” says one complaint. “She’s endangering the public,” says another. 

It’s clear that the institution must issue a press release on the situation, and it falls to Kelechi’s friend Max, as a director of the institution, to decide what kind of statement to put out, and to recommend whether Kelechi’s membership of the institution could – or should – be revoked. Max looks closely at the institution’s Code of Professional Conduct. One part of the Code says that “Members should do nothing that in any way could diminish the high standing of the profession. This includes any aspect of a member’s personal conduct which could have a negative impact upon the profession.” Another part of the Code says: “All members shall have full regard for the public interest, particularly in relation to matters of health and safety, and in relation to the well-being of future generations.” 

As well as the institution’s Code of Conduct, Max considers the historic impact of civil resistance in achieving change, and how those engaging in such protests – such as the suffragettes in the early 1900s – could be viewed negatively at the time, whilst later being lauded for their efforts. Max wonders at what point the tide of public opinion begins to turn, and what causes this change. She knows that she has to consider the potential impacts of the statement that she puts out in the press release; how it might affect not just her friend, but the institution’s members, other potential protesters, and also her own career.  

 

Optional STOP for questions and activities: 

1. Discussion: Historically, has civil resistance been instrumental or incidental in achieving systemic change? Research to find out if and when engineers have been involved in civil resistance in the past. 

2. Discussion: Could Kelechi’s actions, and the results of her actions, be interpreted as having “a negative impact on the profession”? 

3. Discussion: Looking at Kelechi’s actions, and the institution’s code of conduct, should Max recommend that Kelechi’s membership be revoked? 

4. Discussion: Which parts of the quoted code of conduct could Max emphasise or omit in her press release, and how might this affect the tone of her statement and how it could be interpreted? 

5. Activity: Debate which position Max should take in her press release: condemning the actions of the protesters as being against the institution’s code of conduct; condoning the actions as being within the code of conduct; remaining as neutral as possible in her statement. 

6. Discussion: What are the wider impacts of Max’s decision to either remain neutral, or to stand with or against Kelechi in her actions?  

7. Activity: Write a press release for the institution, taking one of the above positions. 

8. Discussion: Which other authorities or professional bodies might be impacted by Max’s decision? 

9. Discussion: What are the potential impacts of Max’s press release on the following stakeholders, and what decisions or actions might they take because of it? Kelechi; Kelechi’s employer; members of the STEM protest group; the institution; institution members; government policymakers; the media; the public; the police; fossil fuel businesses; Max’s employers; Max herself.

Learning and teaching notes: 

This case study considers not only the environmental impacts of a clean technology (the heat pump) but also the social and economic impacts on the end user. Heat pumps form an important part of the UK government’s net-zero plan. Our technical knowledge of heat pump performance can be combined with the practical aspects of implementing and using this technology. However, students need to weigh the potential carbon savings against the potential economic impact on the end user, and consider whether current policy incentivises consumers to move towards clean heating technologies.  

This case study offers students an opportunity to practise and improve their skills in making estimates and assumptions. It also enables students to learn and practise the fundamentals of energy pricing and link this to the increasing issue of fuel poverty. Fundamental thermodynamics concepts, such as the second law, can also be integrated into this study.  

This case study addresses two of the themes from the Accreditation of Higher Education Programmes fourth edition (AHEP4): The Engineer and Society (acknowledging that engineering activity can have a significant societal impact) and Engineering Practice (the practical application of engineering concepts, tools and professional skills). To map this case study to AHEP outcomes specific to a programme under these themes, access AHEP 4 here and navigate to pages 30-31 and 35-37. 

The dilemma in this case is presented in six parts. If desired, a teacher can use the Summary and Part one in isolation, but Parts two to six develop and complicate the concepts presented in the Summary and Part one to provide for additional learning. The case study allows teachers the option to stop at multiple points for questions and/or activities, as desired.

Summary – Heating systems and building requirements: 

You are an engineering consultant working for a commercial heat pump company. The company handles both the manufacture and installation of heat pumps. You have been called in by a county council to advise and support a project to decarbonise both new and existing housing stock. This includes changes to social housing (either directly under the remit of the council or by working in partnership with a local housing association) and also to private housing, encouraging homeowners and landlords to move towards net zero emissions. In particular, the council is interested in the installation of clean heating technologies with a focus on heat pumps, which it views as the most technologically-ready solution. Currently most heating systems rely on burning natural gas in a boiler to provide heat. By contrast, a heat-pump is a device that uses electricity to extract heat from the air or ground and transfer it to the home, avoiding direct emission of carbon dioxide.  

The council sets your first task of the project as assessing the feasibility of replacing the existing gas boiler systems with heat pumps in social housing. You are aware that there are multiple stakeholders involved in this process you need to consider, in addition to evaluating the suitability of the housing stock for heat pump installation.  

 

Optional STOP for questions and activities: 

1. Discussion: Why might the council have prioritised retrofitting the social housing stock with heat pumps as the first task of the project? How might business and ethical concerns affect this decision?  

2. Activity: Use stakeholder mapping to determine who are the main stakeholders in this project and what are their main priorities? In which areas will these stakeholders have agreements or disagreements? What might their values be, and how do those inform priorities?  

3. Discussion: What key information about the property is important for choosing a heating system? What does the word feasibility mean and how would you define it for this project? 

4. Activity: Research the Energy Performance Certificate (EPC):  what are the main factors that determine the energy performance of a building?  

5. Discussion: What do you consider to be an ‘acceptable’ EPC rating? Is the EPC rating a suitable measure of energy efficiency? Who should decide, and how should the rating be determined?  

 

Technical pre-reading for Part one: 

It is useful to introduce the thermodynamic principles on which heat pumps operate in order to better understand the advantages and limitations when applying this engineering technology in a real-world situation. A heat pump receives heat (from the air, ground, or water) and work (in the form of electricity to a compressor) and then outputs the heat to a hot reservoir (the building you are heating). We recommend covering: 

An online, open-source textbook that covers both topics is Applications of Thermodynamics – Heat Pumps & Refrigerators. 

 

Dilemma – Part one – Considering heat pump suitability: 

You have determined who the main stakeholders are and how to define the project feasibility. A previous investigation commissioned by the council into the existing housing stock, and one of the key drivers for them to initiate this project, has led them to believe that most properties will not require significant retrofitting to make them suitable for heat pump installation.  

 

Optional STOP for question and activities: 

1. Activity: Research how a conventional gas boiler central heating system works. How does a heat pump heating system differ? What heat pump technologies are available? What are the design considerations for installing a heat pump in an existing building? 

 

Dilemma – Part two – Inconsistencies: 

You spot some inconsistencies in the original investigation that appear to have been overlooked. On your own initiative, you decide to perform a more thorough investigation into the existing housing stock within the local authority. Your findings show that most of the dwellings were built before 1980 and less than half have an EPC rating of C or higher. The poor energy efficiency of the existing housing stock causes a potential conflict of interest for you: there are a significant number of properties that would require additional retrofitting to ensure they are suitable for heat pump installation. Revealing this information to the council at this early stage could cause them to pull out of the project entirely, causing your company to lose a significant client. You present these findings to your line manager who wants to suppress this information until the company has a formal contract in place with the council.  

 

Optional STOP for question and activities: 

1. Discussion: How should you respond to your line manager? Is there anyone else you can go to for advice? Do you have an obligation to reveal this information to your client (the council) when it is they who overlooked information and misinterpreted the original study? 

2. Activity: An example of a factor that causes a poor EPC rating is how quickly the property loses heat. A common method for significantly reducing heat loss in a home is to improve the insulation. Estimate the annual running cost of using an air-source heat pump in a poorly-insulated versus a well-insulated home to look at the potential financial impact for the tenant (example approach shown in the Appendix, Task A). 

3. Discussion: What recommendations would you make to the council to ensure the housing is heat-pump ready? Would your recommendation change for a new-build property? 

 

Dilemma – Part three – Impact of energy costs on the consumer: 

Your housing stock report was ultimately released to the council and they have decided to proceed, though for a more limited number of properties. The tenants of these dwellings are important stakeholders who are ultimately responsible for the energy costs of their properties. A fuel bill is made up of the wholesale cost of energy, network costs to transport it, operating costs, taxes, and green levies. Consumers pay per unit of energy used (called the unit cost) and also a daily fixed charge that covers the cost of delivering energy to a home regardless of the amount of energy used (called the standing charge). In the UK, currently the price of natural gas is the main driver behind the price of electricity; the unit price of electricity is typically three to four times the price of gas. 

Your next task is to consider if replacing the gas boiler in a property with a heat pump system will have a positive or negative effect on the running costs.  

 

Optional STOP for questions and activities: 

1. Activity: Estimate the annual running cost for a property when using a heat pump versus a natural gas boiler (see Appendix Task B for an example approach). 

2. Discussion: Energy prices are currently rising and have seen drastic changes in the UK over the past year. The lifetime of a new heat pump system is around 20 years. How would rising gas and electric prices affect the tenant? Does this impact the feasibility of using a gas boiler versus a heat pump? How can engineering knowledge and expertise help inform pricing policies? 

 

Dilemma – Part four – Tenants voice concerns: 

After a consultation, some of the current tenants whose homes are under consideration for heat pump installation have voiced concerns. The council is planning to install air-source heat pumps due to their reduced capital cost compared to a ground-source heat pump. The tenants are concerned that the heat pump will not significantly reduce their fuel bills in the winter months (when it is most needed) and instead could increase their bills if the unit price and standing charge for electricity continue to increase. They want a guarantee from the council that their energy bills will not be adversely affected. 

 

Optional STOP for questions and activities: 

1. Discussion: Why would air-source heat pumps be less effective in winter? What are the potential effects of increased energy bills on the tenants? How much input should the tenants have on the heating system in their rented property? 

2. Discussion: Do the council have any responsibility if the installation does result in an increased energy bill in the winter for their tenants? Do you and your company have any responsibility to the tenants?  

 

Dilemma – Part five – The council consultation: 

The council has hosted an open consultation for private homeowners within the area that you are involved in. They want to encourage owners of private dwellings to adopt low-carbon technologies and are interested in learning about the barriers faced and what they can do to encourage the adoption of low carbon-heating technologies. The ownership of houses in the local area is similar to the overall UK demographic: around 20% of dwellings are in the social sector (owned either by the local authority or a housing association), 65% are privately owned, and 15% are privately rented.  

 

Optional STOP for questions and activities: 

1. Activity: Estimate the lifetime cost of running an air-source heat pump and ground-source heat pump versus a natural gas boiler. Include the infrastructure costs associated with installation of the heating system (see Appendix Task C for an example approach). This can be extended to include the impact of increasing energy prices.  

2. Activity: Research the policies, grants, levies, and schemes available at local and national levels that aim to encourage uptake of net zero heating. 

3. Discussion: From your estimations and research, how suitable are the current schemes? What recommendations would you make to improve the uptake of zero carbon heating? 

 

Dilemma – Part six – Recommendations: 

Energy costs and legislation are important drivers for encouraging homeowners and landlords to adopt clean heating technologies. There is a need to weigh up potential cost savings with the capital cost associated with installing a new heat system. Local and national policies, grants, levies, and bursaries are examples of tools used to fund and support adoption of renewable technologies. Currently, an environmental and social obligations cost, known as the ‘green levies,’ are added to energy bills which contribute to a mixture of social and environmental energy policies (including, for example, renewable energy projects, discounts for low-income households, and energy efficiency improvements).  

Your final task is to think more broadly on encouraging the uptake of low-carbon heating systems in private dwellings (the majority of housing in the UK) and to make recommendations on how both councils locally and the government nationally can encourage uptake in order to reduce carbon emissions.  

 

Optional STOP for questions and activities: 

1. Discussion: In terms of green energy policy, where does the ethical responsibility lie –  with the consumer, the local government, or the national government?  

2. Discussion: Should the national Government set policies like the green levy that benefit the climate in the long-term but increase the cost of energy now?  

3. Discussion: As an employee of a private company, to what extent is the decarbonisation of the UK your problem? Do you or your company have a responsibility to become involved in policy? What are the advantages or disadvantages to yourself as an engineer?  

 

Appendix: 

The three tasks that follow are designed to encourage students to practise and improve their zeroth order approximation skills (for example a back of the envelope calculation). Many simplifying assumptions can be made but they should be justified.  

Task A: Impact of insulation 

Challenge: Estimate the annual running cost for an air-source heat pump in a poorly insulated home. Compare to a well-insulated home.  

Base assumptions around the heat pump system and the property being heated can be researched by the student as a task or given to them. In this example we assume:  

Example estimation: 

1. Estimate the overall heat loss for a poorly- and well-insulated property.

Note: heat loss is greater in the poorly insulated building.

 

 2. Calculate the work input for the heat pump.  

Assumption: heat pump matches the heat loss to maintain a consistent temperature.

 Note: a higher work input is required in the poorly insulated building to maintain a stable temperature.

 

3. Determine the work input over a year. 

Assumption: heat pump runs for 8 hours per day for 365 days.

 

4. Determine the running cost 

For an electricity unit price of 33.8 p per kWh.

 

Note: running cost is higher for the poorly insulated building due to the higher work input required to maintain temperature. 

 

Task B: Annual running cost estimation 

Challenge: Estimate the annual running cost for a property when using a heat pump versus a natural gas boiler.  

Base assumptions around the boiler system, heat pump system, and property can be researched by the student as a task or given to them. In this example we assume: 

Energy tariffs (correct at time of writing) for the domestic consumer including the energy price guarantee discount: 

Domestic energy tariffs 
Electric standing charge  51.0p per day 
Unit price of electricity  33.8p per kWh 
Gas standing charge  26.8p per kWh 
Unit price of gas  10.4p per kWh 

 

Example estimation: 

1. Calculate the annual power requirement for each case. 

Assumed heating requirement is 15,000 kWh for the year. 

2. Calculate the annual cost for each case: 

Note: the higher COP of the ground-source heat pump makes this the more favourable option (dependent on the fuel prices).  

 

Task C: Lifetime cost estimation  

Challenge: Estimate the total lifetime cost for a property when using a heat pump versus a natural gas boiler.  

Base assumptions around the boiler system, heat pump system, and property can be researched by the student as a task or given to them. In this example we assume: 

Energy tariffs (correct at time of writing) for the domestic consumer including the energy price guarantee discount: 

Domestic energy tariffs 
Electric standing charge  51.0p per day 
Unit price of electricity  33.8p per kWh 
Gas standing charge  26.8p per kWh 
Unit price of gas  10.4p per kWh 

 

1. Calculate the lifetime running cost for each case.

 

2. Calculate the total lifetime cost for each case.

Case enhancement: Power-to-food technologies

Activity: An ethical evaluation of the technology and its impacts.

Author: Dr Fiona Truscott (UCL).

 

Overview:

This enhancement is for an activity found in the Dilemma Part one, Point 1 section of the case: “Identify different aspects of the production process where ethical concerns may arise, from production to delivery to consumption.” Below are prompts for discussion questions and activities that can be used. Each prompt could take up as little or as much time as the educator wishes, depending on where they want the focus of the discussion to be.

In this group activity, students will act as consultants brought in by the Power to Food team to create an ethical evaluation of the technology and any impacts it may have throughout its lifetime. The aim here is for students to work together to discuss the potential ethical issues at each stage of the production process as well as thinking about how they might be addressed. Groups will need to do research, either in class or at home. Depending on the timeframe you may want to give them a starting point and some basic information found in the case study’s learning and teaching resources.

 

Suggested timeline:

 

Team briefing:

You are a team of consultants brought in by the company who has developed Power to Food technology. Before they go to market they want to understand the ethical issues that may arise from the technology and address them if possible. They want you to look at the process as a whole and identify any ethical issues that might come up. They also want to know how easy these issues might be to address and want you to suggest potential ways to address them. You will need to provide the company with a briefing on your findings.

 

Tools:

It’s useful to give teams some frameworks through which they can do an analysis of the production process. One of those is to discuss who is harmed by the process at each stage. This is harm in the widest possible sense: physical, environment, political, reputational etc. What or who could be impacted and how? Another framework is the values of the people or entities involved in the process: what are they trying to achieve or what do they want and are any of these in conflict? Topics such as sustainability and accessibility also have an ethical dimension, and using these as a lens can help students to look at the problem from a different viewpoint.

 

Prompts for questions:

These are questions that you can get students to answer in class or suggest that they cover in an assessment. This could also be information you give the team so that they can use it as a foundation.

 

Assessment:

This group activity lends itself to a few different assessment formats, depending on what fits with your programme and timeframe. The two key things to assess are whether students can understand and identify ethical issues across the whole Power to Food production process and whether they can discuss ways to address these issues and the complexities that can be involved in addressing these issues. These two things can be assessed separately; for example through a written report where teams discuss the potential issues and a presentation where they talk about how they might address these issues. Or one assessment can cover both topics. This can be a written report, a live or recorded presentation, a video, podcast or a poster. Teams being able to see other teams’ contributions is both a good way of getting them to discuss different viewpoints and makes for a fun session. You can get teams to present their final work or a draft to each other.

Depending on the timeframe, you may also want to build in some skills assessment too. The AAC&U’s VALUE rubrics are a great starting point for assessing skills and IPAC is a good tool for assessing teamwork via peer assessment.

 

Marking Criteria:

Good Average Poor
Understanding and identification of ethics issues across the whole Power to Food production process Has identified and understood context specific ethical issues across the production process. May have shown some understanding of how issues may impact on each other. Has identified and understood broad/general ethical issues around production processes but hasn’t linked much to the specific context of the case study. Some stages may be more detailed than others. Has not identified many or any ethical issues and seems to have not understood what we’re looking for.
Discussing ways to address these issues and the complexities that can be involved Has identified context specific ways to address the ethical issues raised and has understood the potential complexities of addressing those ethical issues. Has identified broad/general ways to address the ethical issues raised and made some reference to differing levels of complexity in addressing ethical issues. Has not identified many or any ways to address the ethical issues raised and seems to have not understood what we’re looking for.
Communication Very clear, engaging and easy to understand communication of the ethical issues involved and ways to address them. Right language level for the audience. Generally understandable but not clear in places or uses the wrong level of language for the audience (assumes too much or not enough prior knowledge). Difficult to understand the point being made either due to language used or disconnection to the point of the assessment or topic.

Case enhancement: Facial recognition for access and monitoring

Activity: Prompts to facilitate discussion activities. 

Author: Sarah Jayne Hitt, Ph.D. SFHEA (NMITE, Edinburgh Napier University).

 

Overview:

There are several points in this case during which an educator can facilitate a class discussion about relevant issues. Below are prompts for discussion questions and activities that can be used. These correspond with the stopping points outlined in the case. Each prompt could take up as little or as much time as the educator wishes, depending on where they want the focus of the discussion to be. The discussion prompts for Dilemma Part three are already well developed in the case study, so this enhancement focuses on expanding the prompts in Parts one and two.

 

Dilemma Part one – Discussion prompts:

1. Legal Issues. Give students ten minutes to individually or in groups do some online research on GDPR and the Data Protection Act (2018). In either small groups or as a large class, discuss the following prompts. You can explain that even if a person is not an expert in the law, it is important to try to understand the legal context. Indeed, an engineer is likely to have to interpret law and policy in their work. These questions invite critical thinking and informed consideration, but they do not necessarily have “right” answers and are suggestions that can help get a conversation started.

a. Are legal policies clear about how images of living persons should be managed when they are collected by technology of this kind?

b. What aspects of these laws might an engineer designing or deploying this system need to be aware of?

c. Do you think these laws are relevant when almost everyone walking around has a digital camera connected to the internet?

d. How could engineers help address legal or policy gaps through design choices?

2. Sharing Data. Before entering into a verbal discussion, either pass out the suggested questions listed in the case study on a worksheet or project on a screen. Have students spend five or ten minutes jotting down their personal responses. To understand the complexity of the issue, students could even create a quick mind map to show how different entities (police, security company, university, research group, etc.) interact on this issue. After the students spend some time in this personal reflection, educators could ask them to pair/share—turn to the person next to them and share what they wrote down. After about five minutes of this, each pair could amalgamate with another pair, with the educator giving them the prompt to report back to the full class on where they agree or disagree about the issues and why.

3. GDPR Consent. Before discussing this case particularly, ask students to describe a situation in which they had to give GDPR consent. Did they understand what they were doing, what the implications of consent are, and why? How did they feel about the process? Do they think it’s an appropriate system? This could be done as a large group, small group, or through individual reflection. Then turn the attention to this case and describe the change of perspective required here. Now instead of being the person who is asked for consent, you are the person requiring consent. Engineers are not lawyers, but engineers often are responsible for delivering legally compliant systems. If you were the engineer in charge in this case, what steps might you take to ensure consent is handled appropriately? This question could be answered in small groups, and then each group could report back to the larger class and a discussion could follow the report-backs.

4. Institutional Complexity. The questions listed in the case study relate to the fact that the building in which the facial recognition system will be used accommodates many different stakeholders. To help students with these questions, educators could divide the class into small groups, with each group representing one of the institutions or stakeholder groups (college, hospital, MTU, students, patients, public, etc.). Have each group investigate whether regulations related to captured images are different for their stakeholders, and debate if they should be different. What considerations will the engineer in the case have to account for related to that group? The findings can then be discussed as a large class.

 

Dilemma Part two – Discussion prompts:

The following questions relate to macroethical concerns, which means that the focus is on wider ethical contexts such as fairness, equality, responsibility, and implications.

1. Benefits and Burdens. To prepare to discuss the questions listed in the case study, students could make a chart of potential harms and potential benefits of the facial recognition system. They could do this individually, in pairs or small groups, or as a large class. Educators should encourage them to think deeply and broadly on this topic, and not just focus on the immediate, short-term implications. Once this chart is made, the questions listed in the case study could be discussed as a group, and students asked to weigh up these burdens and benefits. How did they make the choices as to when a burden should outweigh a benefit or vice versa?

2. Equality and Utility. To address the questions listed in the case study, students could do some preliminary individual or small group research on the accuracy of facial recognition systems for various population groups. The questions could then be discussed in pairs, small groups, or as a large class.

3. Engineer Responsibility. Engineers are experts that have much more specific technical knowledge and understanding than the general public. Indeed, the vast majority of people have no idea how a facial recognition system works and what the legal requirements are related to it, even if they are asked to give their consent. Does an engineer therefore have more of a responsibility to make people aware and reassure them? Or is an engineer just fulfilling their duty by doing what their boss says and making the system work? What could be problematic about taking either of those approaches?

Case enhancement: Developing a school chatbot for student support services

Activity: Stakeholder mapping to elicit value assumptions and motivations.

Author: Karin Rudolph (Collective Intelligence).

 

Overview:

This enhancement is for an activity found in point 5 of the Summary section of the case study.

What is stakeholder mapping?

What is a stakeholder?

Mapping out stakeholders will help you to:

  1. Identify the stakeholders you need to collaborate with to ensure the success of the project.
  2. Understand the different perspectives and points of view people have and how these experiences can have an impact on your project or product.
  3. Map out a wide range of people, groups or individuals that can affect and be affected by the project.

 

Stakeholder mapping:

The stakeholder mapping activity is a group exercise that provides students with the opportunity to discuss ethical and societal issues related to the School Chatbot case study. We recommend doing this activity in small groups of 6-8 students per table.

 

Resources:

 

Materials:

To carry out this activity, you will need the following resources:

1. Sticky notes (or digital notes if online).

2. A big piece of paper or digital board (Jamboard, Miro if online) divided into four categories:

Learning and teaching notes:

This case involves a software engineer who has discovered a potential data breach in a smart home community. The engineer must decide whether or not to report the breach, and then whether to alert and advise the residents. In doing so, considerations of the relevant legal, ethical, and professional responsibilities need to be weighed. The case also addresses communication in cases of uncertainty as well as macro-ethical concerns related to ubiquitous and interconnected digital technology.

This case study addresses two of AHEP 4’s themes: The Engineer and Society (acknowledging that engineering activity can have a significant societal impact) and Engineering Practice (the practical application of engineering concepts, tools and professional skills). To map this case study to AHEP outcomes specific to a programme under these themes, access AHEP 4 here and navigate to pages 30-31 and 35-37.

The dilemma in this case is presented in two parts. If desired, a teacher can use Part one in isolation, but Part two develops and complicates the concepts presented in Part one to provide for additional learning. The case allows teachers the option to stop at multiple points for questions and/or activities as desired

Summary:

Smart homes have been called “the road to independent living”. They have the potential to increase the autonomy and safety of older people and people with disabilities. In a smart home, the internet of things (IoT) is coupled with advanced sensors, chatbots and digital assistants. This combination enables residents to be connected with both family members and health and local services, so that if there there are problems, there can be a quick response.

Ferndale is a community of smart homes. It has been developed at considerable cost and investment as a pilot project to demonstrate the potential for better and more affordable care of older people and people with disabilities. The residents have a range of capabilities and all are over the age of 70. Most live alone in their home. Some residents are supported to live independently through: reminders to take their medication; prompts to complete health and fitness exercises; help completing online shopping orders and by detecting falls and trips throughout the house. The continuous assessment of habits, diet and routines allows the technology to build models that may help to predict any future negative health outcomes. These include detecting the onset of dementia or issues related to dietary deficiencies. The functionality of many smart home features depends on a reliable and secure internet connection.

 

Dilemma – Part one:

You are the software engineer responsible for the integrity of Ferndale’s system. During a routine inspection you discover several indicators suggesting a data breach may have occurred via some of the smart appliances, many of which have cameras and are voice-activated. Through the IoT, these appliances are also connected to Amazon Ring home security products – these ultimately link to Amazon, including supplying financial information and details about purchases.

 

Optional STOP for questions and activities: 

1. Activity: Technical analysis – Before the ethical questions can be considered, the students might consider a number of immediate technical questions that will help inform the discussion on ethical issues. A sample data set or similar technical problem could be used for this analysis. For example:

2. Activity: Identify legal and ethical issues. The students should reflect on what might be the immediate ethical concerns of this situation. This could be done in small groups or a larger classroom discussion.

Possible prompts:

3. Activity: Determine the wider ethical context. Students should consider what wider moral issues are raised by this situation. This could be done in small groups or a larger classroom discussion.

Possible prompts:

 

Dilemma – Part two:

You send an email to Ferndale’s manager about the potential breach, emphasising that the implications are possibly quite serious. She replies immediately, asking that you do not reveal anything to anyone until you are absolutely certain about what has happened. You email back that it may take some time to determine if the software security has been compromised and if so, what the extent of the breach has been. She replies explaining that she doesn’t want to cause a panic if there is nothing to actually worry about and says “What you don’t know won’t hurt you.” How do you respond?     

 

Optional STOP for questions and activities: 

1. Discussion: Professional values – What guidance is given by codes of ethics such as the Royal Academy of Engineering/Engineering Council’s Statement of Ethical Principles or the Association for Computing Machinery Code of Ethics?

2. Activity: Map possible courses of action. The students should think about the possible actions they might take. They can be prompted to articulate different approaches that could be adopted, such as the following, but also develop their own alternative responses.

3. Activity: Hold a debate on which is the best approach and why. The students should interrogate the pros and cons of each possible course of action including the ethical, technical, and financial implications. They should decide on their own preferred course of action and explain why the balance of pros and cons is preferable to other options.

4. Activity: Role-play a conversation between the engineer and the manager, or a conversation between the engineer and a resident.

5. Discussion: consider the following questions:

6. Activity: Change perspectives. Imagine that you are the child of one of Ferndale’s residents and that you get word of the potential data security breach. What would you hope the managers and engineers would do?

7. Activity: Write a proposal on how the system might be improved to stop this happening in the future or to mitigate unavoidable risks. To inform the proposal, the students should also explore the guidance of what might be best practice in this area. For example, in this instance, they may decide on a series of steps.

Topic: Alternative food production.

Engineering disciplines: Energy; Chemical engineering.

Ethical issues: Sustainability; Social responsibility.

Professional situations: Public health and safety; Personal/professional reputation; Falsifying or misconstruing data / finances; Communication.

Educational level: Advanced.

Educational aim: Practise ethical reasoning. Ethical reasoning applies critical analysis to specific events in order to evaluate, and respond, to problems in a fair and responsible way.

 

Learning and teaching notes:

This case involves an engineer navigating multiple demands on a work project. The engineer must evaluate trade-offs between social needs, technical specifications, financial limitations, environmental needs, legal requirements, and safety. Some of these factors have obvious ethical dimensions, and others are more ambiguous. The engineer must also navigate a professional scenario in which different stakeholders try to influence the resolution of the dilemma.

This case study addresses two of AHEP 4’s themes: The Engineer and Society (acknowledging that engineering activity can have a significant societal impact) and Engineering Practice (the practical application of engineering concepts, tools and professional skills). To map this case study to AHEP outcomes specific to a programme under these themes, access AHEP 4 here and navigate to pages 30-31 and 35-37.

Summary:

Power-to-X (P2X) describes a number of pathways for the transformation of electricity to alternative forms. This can be utilised for storing energy for later use, in order to balance periods of excesses and deficits resulting from the use of renewable energy technologies. It can also be used in applications that do not use electricity, such as through the transformation of electricity to hydrogen or other gases for industrial use.

One area that has seen significant development in recent years is power-to-food (PtF). This pathway results in CO2 being transformed, through chemical or biological processes powered by renewable energy, into food. One such process uses electrolysis and the Calvin cycle to create hydrocarbons from CO2, water and bacteria. The end result is a microbial protein, a substance that could be used in animal feed. Ultimately, the technology could produce a meat alternative suitable for human consumption, further reducing the carbon emissions produced by intensive animal farming.

 

Optional STOP for questions and activities: 

1. Activity: Identify the potential harms and risks of this technology, both objective and subjective. For example, could the shift of food production from soil to chemical industries concentrate power in the hands of a few? What public perceptions or cultural values might impact the acceptance or uptake of the technology? 

2. Discussion: Wider context – What social, technological, economic, environmental, political, or legal factors might need to be considered in order to implement this technology?

3. Activity: Research companies that are currently developing P2X technologies. Which industries and governments are promoting P2X? How successful have early projects been? What obstacles exist in upscaling?

4. Activity: Undertake a technical activity in the area of biochemical engineering related to the storing and transforming of renewable energy.

 

Dilemma – Part one:

You are the Chief Technical Officer at a company that has developed PtF technology that can convert CO2 to edible fatty acids (or triglycerides). The potential of CO2 capture is attractive to many stakeholders, but the combination of carbon reduction tied in with food production has generated positive media interest. The company also intends to establish its PtF facility near a major carbon polluter, that will reduce transport costs. However, some nearby residents are concerned about having a new industrial facility in their area, and have raised additional concerns about creating unsafe food.

As part of the process to commercialise this technology, you have been tasked with completing an ethical assessment. This includes an analysis of the technology’s short and long-term effects in a commercial application.

 

Optional STOP for questions and activities: 

1. Discussion and Activity: Identify different aspects of the production process where ethical concerns may arise, from production to delivery to consumption. Which ethical issues do you consider to be the most challenging to address?

2. Discussion: What cultural values might impact the ethical assessment? Does trust play a role in our ethical and consumption decisions? What internal logics / business goals might steer, or influence, the acceptance of various ethical considerations?

3. Discussion: Which areas of the ethical assessment might stakeholders be most interested in, or concerned about, and why?

4. Discussion: Does the choice of location for PtF facilities influence the ethical assessment? What problems could this PtF technology solve?

5. Discussion: What competing values or motivations might come into conflict in this scenario? What codes, standards, or authoritative bodies might be relevant to this? What is the role of ethics in technology development?

6. Activity: Assemble a bibliography of relevant professional codes, standards, and authorities.

7. Activity: Research the introduction of novel foods throughout history and / or engineering innovations in food production.

8. Activity: Write up the ethical assessment of the business case, and include findings from the previous questions and research.

 

Dilemma – Part two:

You deliver your ethical assessment to your manager. Shortly afterwards you are asked to edit the report to remove or downplay some ethical issues you have raised. The company leadership is worried that potential investors in an upcoming financing round may be dissuaded from investing in the company if you do not edit these sections.

 

Optional STOP for questions and activities: 

1. Discussion: Professional and ethical responsibilities – What are the ethical implications of editing or not editing the report? What consequences could this type of editing have? Think about stakeholders such as the company, potential investors and society.

2. Discussion: Wider considerations of business ethics – How would you recognise an ethical organisation? What are its characteristics? What is the role of ethics in business?
