Dr. Nadeer Jeevanjee

“The Landscape of Climate Science”

Climate change is described in some quarters as a “crisis” and in others as a “hoax”, with a range of views in between. How can one square this with climate science, which should be more objective? This talk, led by Nadir Jeevanjee, will emphasize that there is a spectrum of climate science, ranging from well-established, “settled” science (such as global warming due to anthropogenic CO2) to highly uncertain frontier topics (such as various proposed “tipping points”). To properly interpret climate science, one must acknowledge the existence of this spectrum, and appropriately place climate and weather phenomena within it. 

Jeevanjee studies the physics of clouds, radiation, and climate, using a hierarchy of approaches ranging from pencil-and-paper theory to comprehensive computer simulations. He currently is a Research Physical Scientist at NOAA’s Geophysical Fluid Dynamics Laboratory. This event will be co-sponsored by the Science, Technology, and Society network at Temple University.

“New Initiatives in Interdisciplinary Education & Research at Temple University”

The power of a comprehensive research university lies in the vast array of educational offerings at all levels. The sheer size of such an institution, however, presents logistical roadblocks to interdisciplinary collaboration across different Colleges. This includes both undergraduate degree offerings and graduate research opportunities. In Spring 2023, the Provost charged a group of faculty with finding ways to lower these logistical barriers and fostering interdisciplinary education and enhancing interdisciplinary research. This “Interdisciplinary Collaboration Committee” recently completed its work and submitted a detailed report to the Provost.

“Cure Violence Philadelphia: Implementing and Studying Gun Violence Prevention Program at Temple University’s Medical School”

Gun violence is a significant social and medical concern in Philadelphia. As a response, the city develops and funds a variety of interventions to prevent violent injuries caused by gun violence. Lately, more interest and investment has been funneled towards the use of public-health models to prevent gun-violence. Public health programs often use so-called “credible messengers” or “experts by experience” to identify and engage individuals who are at-risk for either gun-related injuries or violent perpetration. Temple University hosts the Cure Violence (CV) program, which is a public-health model to reduce gun violence. CV relies on credible messengers who operate independently of law enforcement and can more easily gain trust in marginalized inner-city communities impacted by violence. Once CV has gained trust, they will identify at-risk individuals and engage them in mentoring to motivate them to leave the streets. Research exploring how CV mentoring can support desistance from gun-violence is scarce. This presentation will focus on: introducing the CV public-health approach to reduce gun violence, discuss the research evidence for it’s effectiveness, and introduce the audience to two ongoing and funded CV research projects in North Philadelphia.

“Getting Well: Opioid Agonist Therapy as Harm Reduction”

Hospitals are critical safety nets that engage patients with opioid use disorder (OUD) in both medical care and recovery from addiction. However, research shows that patients with OUD intentionally delay seeking care, have high rates of self-directed hospital discharge, and frequently require readmission for unaddressed medical problems. This is due, in part, to untreated pain and withdrawal. Standard of care management for withdrawal includes methadone or buprenorphine, but many patients see these options as insufficient or unrealistic due to significantly elevated opioid tolerance from a street supply dominated by highly potent, synthetic opioids such as fentanyl. Using themes derived from qualitative interviews with patients at Temple Hospital with OUD, we make the argument that it is an ethical imperative for hospitals to expand protocols to include long and short-acting opioid agonist medications to treat opioid withdrawal.

“Ethical Considerations in Expanding Available Donor Hearts through Normothermic Regional Perfusion”

Traditional approaches to organ donation have limited the recovery of hearts to only brain dead donors. Recent technology known as normothermic regional perfusion (NRP) has allowed for available donor hearts to expand to non-brain dead deceased donors (i.e., cardiac dead donors). However, because NRP involves restoring a flow of oxygenated blood to the body, as well as a heartbeat, there are ethical considerations to be addressed, among which includes whether such donors really are dead. While NRP can help expand available donor hearts for transplant, the ethical implications must first be considered to prevent moral and actual harm and to ensure continued public trust in the organ donation process.

“The Digital (De)Construction of Food: Encountering taste, pleasure, and satiation in a reapidly interconnected world”

Consuming food media today requires interacting with an endless array of actors—varying in intentions and expertise—each with the potential to impact media users’ health and well-being in positive or adverse ways. At the same time, the growing dissonance between science and facts, influencers, and the public sphere is fostering incessant confusion and contradiction. Intensifying parasocial relationships, or nonreciprocal socio-emotional connections with individuals such as influencers, are rapidly transforming the ways in which we come to understand food and bodies. As media influencers and corporate-sponsored, algorithmically powered content creators exploit the affective power of food for personal gain, locating answers to food-related conundrums now requires traversing a vast information landfill where opinions are plentiful, but legitimacy remains murky.  

My current research aims to unpack the affective ways in which we come to know food through the consumption of social media. I envision media as another somebody in the room, provoking an exchange between creator and consumer, an exchange that ‘does something’. If influence now has the power to supplant science, how do we know what information to take in and which to ignore? Timely and relevant, this paper tackles the increasingly common ways in which we come to know food digitally and further asks who is a creator, who is a consumer, and what is the relationship between them. What are the moral and ethical implications and who stands to gain, or lose, in the social construction of food?

Making Families, Choosing Race: Sperm Banks and the Limits of Diversity

with Alyssa M. Newman, PhD, Georgetown University 

The widespread use of assisted reproductive technologies, coupled with demographic and social change, are normalizing new family configurations that extend beyond biological kinship. Despite the new populations and family formations utilizing these technologies, sperm donor selection is dominated by heteronormative logics and an interest in family resemblance achieved through racial matching. Yet the achievement of racial matching is hardly a given, as 70% of the sperm donors at banks across the United States are white. This talk will interrogate the racialized meanings assigned to donor sperm, drawing on interviews with interracial lesbian couples who encountered difficulties finding a donor of their desired racial background. This talk will also explore the sperm banks’ “diversity problem,” examining how, despite the fertility industry’s quick embrace of diversifying family formations including queer clients and intended parents of color, it continues to center around the reproduction of the white family. In a context of increasing state control over reproduction, the rise of both regulated as well as unregulated sperm markets raises the question of who is being served, or controlled, in the presence or absence of state intervention and policy.

The Industrialization of the Deep Ocean: Can we avoid the Tragedy of the Commons on the High Seas?

with Prof. Erik Cordes, Department of Biology 

As we struggle to move beyond fossil fuels and avoid the most catastrophic outcomes of global climate change scenarios, we are increasingly turning to the ocean and the emerging Blue Economy for solutions. Our fisheries are moving into deeper waters further offshore, we are drilling for oil and gas in places that were thought impossible a few years ago, and emerging industries like deep-sea mining and marine genetic resources are looking to international waters as a way to avoid the regulations and expense of working with the exclusive economic zones of nation-states. Currently, there are negotiations underway at the UN to govern these activities, which range from the designation of the management entity to the methodology for determining environmental impacts. Among these consideration is the proper valuation of ecosystem services and the creation of a global fund that would contain the dividends from the extraction of natural resources. Because these considerations are happening at a global scale, beyond areas of national jurisdiction, we have an opportunity to consider some new(ish) ideas related to ownership, nature’s rights, and a global universal income. Time will tell whether any of these creative ideas gain traction in this forum.

A discussion of the partisanization of science.

Prof. Bruce Hardy

(Dept. of Communication and Social Influence, Klein College of Media and Communication)

There exists a narrative in the United States that Democrats are pro-science and Republicans are anti-science. This narrative was exacerbated by the Covid-19 pandemic. Such partisanization of science is detrimental to the norms of science, the scientific enterprise, the legitimacy of scientists and experts, and may foster public perceptions that science is owned by a political party. Partisanization of science breeds misinformation and reinforces ingroup/outgroup divisions. Bruce Hardy will discuss how we got here, what science communication and STS scholars can do about it, and what to expect in the future.

Discussion with Asta Zelenkauskaitė, author of:

“Creating Chaos Online: Disinformation and Subverted Post-Publics”

With the prevalence of disinformation geared to instill doubt rather than clarity, Creating Chaos Online unmasks disinformation when it attempts to pass as deliberation in the public sphere and distorts the democratic processes. Asta Zelenkauskaitė finds that repeated tropes justifying Russian trolling were found to circulate across not only all analyzed media platforms’ comments but also across two analyzed sociopolitical contexts suggesting the orchestrated efforts behind messaging. Through a dystopian vision of publics that are expected to navigate in the sea of uncertain both authentic and orchestrated content, pushed by human and nonhuman actors, Creating Chaos Online offers a concept of post-publics. The idea of post-publics is reflected within the continuum of treatment of public, counter public, and anti-public. This book argues that affect-instilled arguments used in public deliberation in times of uncertainty, along with whataboutism constitute a playbook for chaos online.

STS NOW! – Conversations in Science, Technology, Society

Andrew Spence (Engineering)

 Neuromachanics, Neurogenetics, and Spinal Cord Injury:

 

Uncovering the mechanisms of movement and how they may help us improve recovery from a paralyzing injury. 

Movement is key to health and quality of life. Yet our understanding of the principles we use to control our bodies and the clever mechanisms that have evolved to get us around are far from complete. Furthermore, hundreds of thousands of people in the US alone are living with spinal cord injuries, reducing their quality of life, with few treatments available. This talk will present work seeking to understand how we control our movement, asking why legged locomotion tends to look like bouncing over a pogo stick. It will then move into more recent work that seeks to understand how forms of spinal cord stimulation help improve recovery from a spinal cord injury, employing new genetic tools that allow for ever more sophisticated manipulation and tracing of neural networks.

Divest, Delay, or Distract: Managing Conflicting Stakeholders amid Industry Disruption 

While managers prefer to integrate the interests of multiple stakeholders, these groups often have conflicting goals. Industry disruptions intensify these conflicts, with some stakeholders favoring the status quo and others encouraging change. We investigate how managers balance conflicting stakeholders under such duress. Using the context of the U.S. electricity industry from 2008-2015, we find that inertial and activist stakeholders influence the divestment of coal generators in opposite directions. Further, by disentangling divestment announcements from implementation and considering the additional outcome of solar investments, we show how managers use strategic delay and distraction to mollify activists, while also benefitting inertial stakeholders.

Brian Hutler (Philosophy) – Health Disparities and Indirect Discrimination: Two Puzzles, One Solution

Hybrid Event: Charles Library 364 and https://temple.zoom.us/j/92510796770

Health disparities, especially racial and ethnic health disparities, are often unjust. But what makes these health disparities unjust? Theorists typically explain this injustice by pointing to some other injustice that either causes, or is caused by, the health disparities. But I will argue that these “causal” accounts of the injustice are incomplete and that we should look for an alternative account. Similarly, theorists struggle to explain the apparent “wrongness” of indirect discrimination in healthcare, e.g., when a hospital’s policies negatively impact protected groups but are not motivated by racism or other forms of animus. In this talk, I will argue that both of these theoretical puzzles admit of a single solution: Both the injustice of health disparities and the wrongness of indirect discrimination in healthcare can be explained by appeal to the right to health. According to the conception of the right to health that I will propose, both reflect failures on the part of relevant duty-bearers to fulfill the obligations they have to relevant rights-holders. I will argue, in conclusion, that the ability to resolve this pair of theoretical puzzles lends support to the conception of the right to health proposed here.
