"Perturbing children's voices to learn how they speak"
feedback, the sound of our own voices, is an important source of
information for the correct production of speech sounds. To understand
how this feedback contributes to speech development, children's auditory
feedback can be experimentally perturbed in real time, and their
compensatory speech productions recorded and analyzed. Novel analyses
methods reveal that younger and older children may compensate
differently, suggesting that auditory feedback plays different roles in
the children's speech as they mature.

"Designing a wearable device to monitor the performance of prosthetic knees"
one in every 150 North Americans currently live with an amputation, 20%
of which have an amputation above the knee. Above-knee amputees rely on
prosthetic knees among other components (foot, socket, pylon, etc.) for
ambulation. Studying how these knees perform and tuning the knee to
provide amputees with a gait as optimal as possible can be a challenge
given that gait analysis equipment is expensive, and a large portion of
amputees live in the developing world with limited or no access to
advanced measurement resources. Moreover, a system does not currently
exist that can directly monitor the internal components of a prosthetic
knee during daily gait activities. To solve this problem, this research
provides a proof-of-concept device, usable in a wide variety of
environments, which directly measures the function of the prosthetic
knee. The goal for the final device is to be sent to countries around
the world to gather data from a vast number of amputees, and to use this
data for improving current and future prosthetic knee designs.

"Building the future through social innovation"
innovation is a yet another site of struggle. Popular discourse frames
social innovation as space of benevolence. Like a hammer, social
innovation can be used to build beautiful things or can be used to
destroy. Social innovation is about systems change and transformation.
For social innovation to become a field or discipline, it must move
beyond a discourse of benevolence. Social innovation is a framework for
building the future. It is still to be determined if that future will be
judged as positive, however we define the future.

"Embodied Knowing and Measured Deficits: Whose Knowledge Counts in Adult Literacy?"
Audrey present her thesis research on the (dis)connections between
current policy about the meaning and measuring of literacy and learning
and the self-knowledge of adult literacy learners. Drawing on concepts
from New Literacy Studies and Disability Studies, and using Narrative
Inquiry approaches, she will discuss how the prevailing norming
practices in adult literacy policy discourse objectify and shame
learners, treat them as bodies of deficiency, and obscure the embodied
process of learning. She will also contrast such constructs of measured
deficits with adult literacy learners embodied knowledge, particularly
how they make meaning of their own literacy and learning.

"MovieGraphs: Understanding Human-Centric Situations from Videos"
Socially intelligent robots is an interesting avenue in artificial intelligence. This requires machines to have the ability to "read" people's emotions, motivations, and other factors that affect behavior. Towards this goal, we introduce a novel dataset called MovieGraphs which provides detailed graph-based annotations of social situations depicted in movie clips. These graphs capture details about human interactions, relationships, and also emotions, and are grounded in the video using time stamps. We provide a thorough analysis of our dataset, showing interesting common-sense correlations that emerge between different social aspects of scenes, as well as across scenes over time. We propose a method for querying videos and text with graphs, and show that: 1) our graphs contain rich and sufficient information to summarize and localize each scene; and 2) subgraphs allow us to describe situations at an abstract level and retrieve multiple semantically relevant situations. We also propose methods for interaction understanding via ordering, and reasoning about the social scene.

"Emergency Medical Response Optimization in Developing Urban Centres"
The lack of emergency medical transportation is viewed as the main barrier to the access and availability of emergency medical care in low and middle-income countries (LMICs). In this talk, we present a robust optimization approach to optimize both the location and routing of emergency response vehicles, accounting for uncertainty in travel times and spatial demand characteristic of LMICs. We traveled to Dhaka, Bangladesh, the sixth largest and third most densely populated city in the world, to conduct field research resulting in the collection of two unique datasets that inform our approach. This data is leveraged to develop machine learning methodologies to estimate demand for emergency medical services in a LMIC setting and to predict the travel time between any two locations in the road network for different times of day and days of the week. We combine our robust optimization and machine learning frameworks with real data to provide an in-depth investigation into three policy-related questions. Our results provide practical insights for emergency response optimization that can be leveraged by hospital-based and private ambulance providers in Dhaka and other developing urban centers.

Global Affairs and the Rule of Law
Haim Abraham, SJD Candidate (Faculty of Law)
"The Combatant Activities Exception and The Rule of Law"
a person carelessly breaks your arm, she will have to compensate you
for your medical expenses, lost wages, pain, and suffering. This notion
is enshrined in tort law, the body of law that is applied by courts in
civil cases to provide compensation for individuals wronged by others.
Yet, if such injuries are inflicted by states on civilians during war,
no compensation is awarded, leaving civilians with no mechanism of
obtaining a remedy for their injuries. The reason for this lack of
liability lies in the "combatant activities exception" that states have
in their domestic legislation, which provides them with blanket immunity
from any tort liability for injuries inflicted during war. However,
this immunity from liability for losses caused by states during battle
is an exception to the rule of law, as it provides states special
privileges. Hence, the immunity increases the risk of infringements of
rights on the battlefield. This presentation will offer a review of the
combatant activities exception and its development. Furthermore, it will
demonstrate the risks the exception poses to the rule of law by drawing
on examples from Canada, Israel, and the United States.

"Responsibilities Without Rights: Debating the Legality of the Responsibility to Protect (R2P)"
in recent memory by the North Atlantic Treaty Organization's (NATO)
illegal use of force in Kosovo in 1999, "just" military interventions
conducted in the name of human protection pose a moral challenge to
contemporary international law. The converse scenario, a technically
legal albeit iniquitous breach of a state's territorial integrity for
humanitarian reasons, is no less problematic. Where moral and legal
rationales for employing military means toward humane ends do not
overlap, the so-called "humanitarian intervention dilemma" arises from
the tension between law as it is and law as it ought to be. In response
to the international community's failure to avert multiple instances of
mass atrocities in the 1990's, the Responsibility to Protect (R2P) arose
as a normative attempt to reconcile the moral imperatives of the
international human rights regime with the prerogatives of state
sovereignty laid out in Article 2(4) of the Charter of the United
Nations (UN). By shifting the emphasis from a moral right to intervene
to a legal responsibility to protect, R2P's norm entrepreneurs sought to
consolidate moral qualifications into an otherwise absolute legal
concept of sovereignty, thereby rendering it conditional and dependent
for its legitimacy on the fulfilment of the basic duty of human
While this new language of humanitarian intervention
might incentivize states to "work" to achieve the legitimacy of their
sovereignty rather than simply take it for granted, I argue that it has
failed to address the very question by which it was initially motivated:
Under what conditions does the validity of international law become
compromised? How one approaches this question determines their legal
interpretation of NATO's military interventions in Kosovo and Libya;
President Donald Trump's recent military strikes on a
government-controlled airbase in Syria; and retroactive justifications
of the Iraq War. Largely absent from academic and policy analyses of
such contentious cases involving the use of force against a sovereign
state, the landmark debate between H.L.A. Hart and Lon Fuller in 1958
indirectly attempted to address this question by offering competing
perspectives on the nature of the relationship between law and morality.
In support of my argument, I revive the exchange between the two legal
theorists, employing each of Hart's legal positivism and Fuller's
natural law theory to reveal the legal shortcomings of R2P as an
institutionalized norm of human protection in the international

"The Long Path Towards Finding Habitable Exo-Worlds"
we are still decades away from discovering life on worlds outside of
our own solar system, much progress is being made today to identify the
best potential candidates for hosting such life. In this talk I will
discuss what we currently know about so-called exoplanets and how we
know it. I will then highlight the steps that will be taken in the
not-so-distant future to further our understanding of exoplanetary
atmospheres and potentially even their surface conditions using extreme
telescopes in hope that one day these efforts will culminate with the
probable detection of Earth-like life elsewhere in the galaxy.

"Disrupting the Food Desert/Oasis Binary: Ethnic Grocery Retailers and Food Access in Humbermede, Toronto"
term "food desert" has been used to identify residential areas where
people may have a limited ability to access healthy, high quality, and
affordable food due to an absence of grocery stores. Such food deserts
have been seen by some to exist in opposition to "food oases," areas
where grocery purchasing venues are abundant. The recent literature on
food deserts, oases, and access more broadly, however, often disregards
'"ethnic" grocery retailers as sources of food, or assumes them to be
attractive shopping sites for all individuals. Moreover, this body of
research frequently frames access as an issue of spatial proximity to
grocery stores. Drawing on interviews I conducted with residents of
Humbermede, Toronto, I explore how food accessibility is perceived and
experienced in a culturally-diverse neighbourhood where the only grocery
retailers present are ethnic in nature. I argue that cultural
identity-related factors and class-based aspects of one's life
circumstances -- not merely distance -- coalesce to influence
understandings of one's food retail environment and one's store choices.
Because these characteristics can differ on individual bases, multiple
interpretations of the level of food retail provision in a neighbourhood
are possible. These findings highlight the limitations of using simple
labels ("deserts" or "oases") to describe grocery shopping landscapes;
as this research shows, food shoppers are not homogenous, all retailers
are not equally attractive to all consumers, and food access has
important socio-cultural, economic, and spatiotemporal dimensions.

"Eating disorders in the margins. On troubled eating experiences in the Latinx community"
presentation provides a brief overview of my doctoral research, which
lies at the intersection of inquiries on bodies, mental health,
activism, experiences of living "in between" cultural experiences and
across borders, and experiences of being racialized or otherwise
marginalized through the presumption of being "out of place." My
research asks: how might one create grassroots organizing spaces of
healing and recovery that empower latinx folks to heal and reclaim our
bodies, and how might they best be configured to help us understand
experiences of eating disorders and troubled eating practices?

"Afro-Peruvians and Citizenship in Peru"
presentation will address issues arising from my doctoral project,
which focuses on how territorial identity and notions of blackness are
constructed in Lima, a self-identified mestizo city. Using frameworks of
feminist political ecology and
black geographies, I aim to initiate a theoretical and empirical
conversation on how blackness has been negotiated in a territory where
only whites and mestizos are given the possibility of establishing a
relationship with the land. Moreover, I attempt to unveil the power
relations between the Peruvian governments and the Afro-descendant
population that have determined the latter's exclusion from the city's
identity and the full benefits of citizenship. Key questions include the
following: How are land and territory conceptualized by the Peruvian
state? More precisely, how is the indigeneity to the land defined in
Peru? Can Afro-Peruvians be considered among the indigenous peoples from
Peru? My research will blend qualitative and quantitative methods to
map how Afro-Peruvians shape space through land and housing in Lima.

"Undressed Toronto: Tracking the history of vernacular bathing and the commercial beach in a turn-of-the-century Canadian city, 1850-1930"
Dale's research demonstrates how bathing in the nineteenth century was a predominantly male nude practice, often done in Toronto's semi-industrialized areas, and that bathers, more often than not, were coddled rather than policed by a middle-class elite who harboured their own fond memories of similar experiences. In this narrative the beach, as both a physical and social space, emerges as a conscious product intended to initiate a new heterosocial system of bathing.
