Angiogenesis is a complex morphogenetic process regulated by growth factors, but also by the force balance between endothelial cells traction stresses and extracellular matrix viscoelastic resistance. Studies conducted with in vitro angiogenesis assays demonstrated that decreasing ECM stiffness triggers an angiogenic switch that promotes organization of EC into tubular cords or pseudo-capillaries. Thus, mechano-sensitivity of EC with regard to proteases secretion, and notably matrix metalloproteinases, should likely play a pivotal role in this switching mechanism. While most studies analysing strain regulation (...) of MMPs used cell cultured on stretched membranes, this work focuses on MMP expression during self-assembly of EC into capillary-like structures within fibrin gels, i.e. on conditions that mimics more closely the in vivo cellular mechanical microenvironment. The activity of MMP-2 and MMP-9, two MMPs that have a pivotal role in capillaries formation, has been monitored in pace with the progressive elongation of EAhy926 cells that takes place during the emergence of cellular cords. We found an increase of the zymogen proMMP-2 that correlates with the initial stages of EC cords formation. However, MMP-2 was not detected. ProMMP-9 secretion decreased, with levels of MMP-9 kept at a rather low value. In order to analyse more precisely the observed differences of EAhy926 response on fibrin and plastic substrates, we proposed a theoretical model of the mechano-regulation of proMMP-2 activation in the presence of type 2 tissue inhibitor of MMPs. Using association/dissociation rates experimentally reported for this enzymatic network, the model adequately describes the synergism of proMMP-2 and TIMP-2 strain activation during pseudo-capillary morphogenesis. All together, these results provide a first step toward a systems biology approach of angiogenesis mechano-regulation by cell-generated extracellular stresses and strains. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Feminist Studies 47, no. 1. © 2021 by Feminist Studies, Inc. 15Candice Lyons Behind the Scenes: Elizabeth Keckley, Slave Narratives, and the Queer Complexities of Space In the fall of 1867—just two years after the conclusion of the American Civil War—former First Lady Mary Todd Lincoln, finding herself in dire financial straits, traveled incognito to New York. She hoped to sell select pieces from her famed wardrobe (...) in order to supplement her income, which was, at the time, rather meager. Accompanying the recently widowed socialite was her self-described “modiste” and “confidante ” Elizabeth Keckley, a formerly enslaved African American dressmaker who had been “intimately associated” with Lincoln for years.1 Despite the various measures undertaken to ensure the scheme’s success, including attempts to extort monied East Coast Republicans and strategic appeals to the press, it ultimately proved fruitless. Political nemeses seized on the opportunity to publicly mock Lincoln, who was seen as an “extravagant and improper” social climber, for her “pecuniary embarrassment,” treating the public auction of her clothing as a spectacle akin to the World Fair.2 Eventually, the former First Lady was forced to retreat to her home in Chicago, leaving Keckley behind to tend to her affairs. 1. Elizabeth Keckley, Behind the Scenes: Or, Thirty Years a Slave and Four Years in the White House (New York: Open Road Integrated Media, 2015): Location no. 406, 54, 53. 2. Carolyn Sorisio, “Unmasking the Genteel Performer: Elizabeth Keckley’s Behind the Scenes and the Politics of Public Wrath,” African American Review 34 (2000): 20; Keckley, Behind the Scenes, Location no. 1321. 16Candice Lyons This decision, however, left the ordinarily sought-after seamstress in dire straits of her own, given that the time she was compelled to dedicate to what would come to be known as “The Old Clothes Scandal ” necessitated closing down her then-thriving business in Washington, DC.3 This, coupled with the fact that indemnification for her services was not forthcoming from Mrs. Lincoln, was likely at least partially at the root of Keckley’s decision to publish her now-infamous memoir, Behind the Scenes: Or, Thirty Years A Slave and Four Years in the White House in 1868.4 Keckley explained that she penned her autobiographical text in a bid to “defend [her]self” and Lincoln against charges of impropriety following the New York incident. However, perhaps unsurprisingly, the book’s release had the exact opposite effect: Keckley’s literary disclosures were met with scorn, regarded by large swaths of white Americans, including some of the same people who had been most vocal in their condemnation of Mary Todd Lincoln, as constituting a set of socially impermissible transgressions of class, race, and gender. Sales of the book were subsequently suppressed, Keckley’s relationship with Lincoln (who had been caught off guard by the text’s release) came to an abrupt end, and there was even a brief, parodic pamphlet produced, titled Behind the Seams; by a Nigger Woman Who Took in Work from Mrs. Lincoln and Mrs. Davis, which cast the entire ordeal as a sort of (racist) cautionary tale.5 Given the clear disdain held for Lincoln by people across the political spectrum at the time, it can be difficult to make sense of the visceral reaction prompted by Keckley’s airing of the controversial figure’s dirty laundry (pun intended). Considering the ways Behind the Scenes implicitly challenged the fixity of hierarchical distinctions between Black and white, employee and employer, however, repudiation of the work might be understood as inevitable. Further, given the “intimate” and ambiguous nature of Lincoln and Keckley’s relationship, the book may also 3. Sorisio, “Unmasking the Genteel Performer,” 19. 4.

Carruthers rejects developmental evidence based primarily on an argument regarding one skill in particular: understanding false beliefs. We propose that this rejection is premature; and that identifying and examining the development of other subcomponent skills important for metacognition and mindreading, such as the ability to assess levels of knowledge, will in fact be useful in resolving this debate.

Addiction: A Philosophical Approach CHAPTER ABSTRACTS “Introduction: Dismantling the Catchphrase” byCandice Shelby Shelby dismantles the catchphrase “disease of addiction.” The characterization of addiction as a disease permeates both research and treatment, but that understanding fails to get at the complexity involved in human addiction. Shelby introduces another way of thinking about addiction, one that implies that is properly understood neither as a disease nor merely as a choice, or set of choices. Addiction is a phenomenon emergent from a (...) complex dynamic system that is at once physical, psychological, social, and more. “A Philosophical Analysis of Addiction” byCandice Shelby Shelby brings much-needed clarity to the discourse surrounding the topic of addiction. Arguing that addiction can neither properly be understood as a disease nor as merely a set of choices, Shelby exposes the weaknesses of both approaches. She shows that addicted persons do not exhibit the elements characteristic of compulsion, nor does an account of addiction in terms of weakness of will, or irrational choosing, provide a satisfying explanation. Instead, by replacing traditional substance ontology with process ontology, and accepting the reality of emergent entities, a coherent account of persons, minds, and addiction can be provided. A fundamental philosophical shift is necessary to see that bodies, minds, values, and addictions are all part of the natural world. “Addiction at the Individual Level” byCandice Shelby Shelby discusses the most influential accounts of addiction as it is understood at the purely individual level. From hedonic theories to incentive sensitization, to habit theories of addiction, to behavioral theories and the ego depletion theory, Shelby considers a variety of approaches to understanding addiction in individuals, as framed in both psychological and in neuroscientific terms. She notes some important caveats that should be considered before accepting the research regarding addiction at the individual level, namely that the scanning studies that are so popularly used to characterize addiction in neurobiological terms are ambiguous, and rely on numerous assumptions that may be false, and that certainly mislead. Shelby provides much-needed critique of both disease and choices models as they characterize addiction at the individual level. “Addiction and the Local Environment” byCandice Shelby Shelby argues that human addiction cannot be understood without serious consideration of the individual’s local environment, her home and family. From the gestational environment to interactions with caregivers during post-natal development to the adult environment in which people become addicted, Shelby shows that no one becomes an addict in a vacuum. Stress is a major influence in the environment throughout life, and has serious consequences for addictive vulnerability. Genetic influences as well are important to addictive vulnerability, but genes always express in interaction with their environment. Social acceptance or rejection is another particularly important factor in the local environment with respect to both coming to be addicted and transitioning out of it. “The Relation Between Addiction and Culture” byCandice Shelby Shelby provides a groundbreaking analysis of the relation between addicts and the cultures that breed them. In this cultural critique, Shelby shows that addictions to certain substances have historically been both the solution to the problem of how to grow economies and control people, and a problem for economic productivity and controlling citizens. Not all cultures have even the concept of addiction, while others, such as the contemporary Western world, and the U.S. in particular, seem to foster it. Shelby shows that addiction is both a cultural construct and, from another way of thinking about it, the result of conditions created by particular cultures. Social inequities, alienation, driving capitalism, and in particular the power of pharmaceutical companies, all contribute to the spiraling endemic of addiction. “Addiction and Meaning” byCandice Shelby Shelby provides a unique argument that understanding how meanings work is essential to a complete analysis of addiction. Individuals experiencing addiction and those who care about and for them often utterly fail to communicate. This is because their respective systems of meanings come to be significantly different. Meanings are not, Shelby argues, best understood in the symbolic terms that characterized the theory of language in the 20th century, but are better apprehended as emotion-rich prototypes carved from repeated interaction with the world. Becoming addicted essentially changes one’s entire system of meanings. Requisite to transitioning out of addiction is a Gestalt-type shift in one’s system of meanings. This holistic way of understanding meanings also provides one level of explanation of what happens when an addict relapses. “The Phenomenology of Addiction and its Implications” byCandice Shelby One way of judging theories of addiction is by how well they capture the phenomenal descriptions that addicts give of their own experiences. Shelby considers variations on 5 basic patterns of addictive experience through the eyes of particular individuals who lived through addictive periods, and shows how even the most influential theories of addiction fail to capture all of them. She argues that an important implication of taking the details of individuals’ addictive stories seriously is that addiction must be understood as a personal phenomenon emergent from a particular complex dynamic system. As her theory of addiction would lead one to expect, no two addicts are the same, and no single-focus theory can explain why not. “Possibilities for Transitioning Out of Addiction” byCandice Shelby Shelby provides numerous strategies for transitioning out of addiction. Given that the vast majority of addiction treatment programs currently available are 12-step based and only successful about 5-8% of the time, it is essential that other approaches be undertaken. Shelby canvasses a variety of options for helping addicted individuals to make the transition out of their troubled pattern of thinking and behaving. From direct brain interventions to drugs to trauma therapy to exercise and nutrition to habit reformation to use of narrative and changing one’s social context as ways of redefining the self, Shelby shows that the possibilities for transitioning out of addiction are legion. Perhaps the best approach is to understand addiction treatment in terms of providing physical, psychological, and social tool kits. “Addiction Emerges from a Complex Dynamic System” byCandice Shelby Shelby considers whether there truly exists such a thing as “an addict” or “addictive thinking” in the universal sense. She concludes that within the context of disruptive substance use or repetitive engagement in certain activities, ordinary human cognitive biases and behavior patterns are categorized as addictive. Addiction, she argues, is best understood as an irreducible human reality, emergent from a sufficiently complex dynamic system (an organism with self-awareness, within a particular cultural milieu) that is both shaped by and contributes to the shaping of its environment. Attempts to simplify addiction into one or a few dimensions may create a solvable problem, but by doing so they fail to solve the real one. (shrink)

Nach Leibniz ist der Schliissel zu metaphysischer Wahrheit Gottes ontologische und moralische Perfektion. In Übereinstimmung mit seiner unendlichen Güte erschafft Gott eine maximal perfekte Welt. Diese maximale Perfektion beinhaltet, daß alle Aspekte der Erschaffungen Gottes einem Gesetz der Kontinuität gehorchen – "die Natur macht keine Sprünge", und daher beinhaltet jeder Übergang Kontinuität. Die unendliche Güte Gottes beinhaltet auch unendliche Gerechtigkeit. Für Leibniz verlangt die Gerechtigkeit Gottes aber, daß die Kreaturen, die für ihre Handlungen verantwortlich sind, besonderer Art sein müssen: sie (...) wurden im Bilde Gottes erschaffen; das heißt, daß sie selbst rationale Schöpfer sind. Dies scheint einen grundsätzlichen Unterschied von alien anderen Kreaturen vorauszusetzen, was aber augenscheinlich einen Verstoß gegen das Gesetz der Kontinuität wäre. Die Autoren behandeln die Frage, ob Leibniz tatsächlich beide Prinzipien benutzt und ob – und wenn ja wie – er das folgegerecht tun kann. (shrink)

Much research on memory for binding depends on incidental measures. However, if encoding associations benefits from conscious attention, then incidental measures of binding memory might not yield a sufficient understanding of how binding is accomplished. Memory for letters and spatial locations was compared in three within-participants tasks, one in which binding was not afforded by stimulus presentation, one in which incidental binding was possible, and one in which binding was explicitly to be remembered. Some evidence for incidental binding was observed, (...) but unique benefits of explicit binding instructions included preserved discrimination as set size increased and drastic reduction in false alarms to lures that included a new spatial location and an old letter. This suggests that substantial cognitive benefits, including enhanced memory for features themselves, might occur through intentional binding, and that incidental measures of binding might not reflect these advantages.

While the addiction treatment industry holds steadfast to the idea that addiction is a disease, and the choice theorists maintam to the contrary that it is justa choice, the truth is not as simple as either. The idea of addiction is a social construct that evolved over the 20th century to encompass increasingly morephenomena, while becoming increasingly conceptually less clear. Taking a complex dynamic systems approach, rather than relying on either the obscure disease notion or the naive choice concept allows (...) us to conceive of the organism, the mind, and the addiction as essentially temporal and emergent. From thisperspective, physical, mental, and social causes operate within one dynamic system, allowing for genetic, developmental, and environmental effects to be understood within a single framework. Such a framework offers much greater hope for successfully addressing the issue than does either the currently dominant disease paradigm or choice theory. (shrink)

Despite the fact that the reductio ad absurdum argument is a valid deductive form, while the slippery slope argument is most often presented as a fallacious form of inductive argument, the two argument types bear some striking similarities. Investigation of these similarities reveals some more universal difficulties in the teaching of informal logic, and, in particular the difference between strong informal arguments and fallacious ones.

This paper engages with the concept of the migrant subject, as framed through contemporary literature on migrancy, and read through the Pauline Ingle photographic collection, located in the Eastern Cape. As against gendered historiographies of labour migrancy and the associated meanings attributed to the rural as a site of social reproduction, Ingle's photographs invite a series of atypical readings that unsettle these subjectivities. Rather, they suggest social and political acts that presage and constitute a migrant citizenship, one that undermines the (...) dichotomy of the rural and urban and projects the possibility of reading the history of the subject in the Eastern Cape differently.

When someone encounters an explanation perceived as weak, this may lead to a feeling of deprivation or tension that can be resolved by engaging in additional learning. This study examined to what extent children respond to weak explanations by seeking additional learning opportunities. Seven‐ to ten‐year‐olds (N = 81) explored questions and explanations (circular or mechanistic) about 12 animals using a novel Android tablet application. After rating the quality of an initial explanation, children could request and receive additional information or (...) return to the main menu to choose a new animal to explore. Consistent with past research, there were both developmental and IQ‐related differences in how children evaluated explanation quality. But across development, children were more likely to request additional information in response to circular explanations than mechanistic explanations. Importantly, children were also more likely to request additional information in direct response to explanations that they themselves had assigned low ratings, regardless of explanation type. In addition, there was significant variability in both children's explanation evaluation and their exploration, suggesting important directions for future research. The findings support the deprivation theory of curiosity and offer implications for education. (shrink)

What are our responsibilities in the face of injustice? How far should we go to fight it? Many would argue that as long as a state is nearly just, citizens have a moral duty to obey the law. Proponents of civil disobedience generally hold that, given this moral duty, a person needs a solid justification to break the law. But activists from Henry David Thoreau and Mohandas Gandhi to the Movement for Black Lives have long recognized that there are times (...) when, rather than having a duty to obey the law, we have a duty to disobey it. -/- Taking seriously the history of this activism, A Duty to Resist wrestles with the problem of political obligation in real world societies that harbor injustice.Candice Delmas argues that the duty of justice, the principle of fairness, the Samaritan duty, and political association impose responsibility to resist under conditions of injustice. We must expand political obligation to include a duty to resist unjust laws and social conditions even in legitimate states. -/- For Delmas, this duty to resist demands principled disobedience, and such disobedience need not always be civil. At times, covert, violent, evasive, or offensive acts of lawbreaking can be justified, even required. Delmas defends the viability and necessity of illegal assistance to undocumented migrants, leaks of classified information, distributed denial-of-service (DDoS) attacks, sabotage, armed self-defense, guerrilla art, and other modes of resistance. There are limits: principle alone does not justify law breaking. But uncivil disobedience can sometimes be not only permissible but required in the effort to resist injustice. (shrink)

Ronald Dworkin argues in Justice for Hedgehogs that citizens have a moral duty to obey the law of polities structured by special and reciprocal concern for all, although they have no such obligation in political communities that violate their members’ dignity. In this chapter, I use Dworkin’s own theory to develop an account of citizens’ associative obligations in the face of political threats to, and violations of, dignity. I argue that four related obligations of resistance require citizens to communicate opposition (...) to a law, policy, institution, or system, rectify oppressive arrangements, assert their dignity; and express solidarity with the oppressed. In light of the pervasiveness of laws that disregard human dignity, I conclude that citizens’ main role is to resist rather than obey the law. (shrink)

What I dub the “worst-result” principle is a criterion that identifies civil war and tyranny as the worst evils that could befall a state, and prescribes their prevention. In this thesis, I attempt to define the worst-result principle’s concrete prescriptions and institutional arrangements to meet these. To do so, I explore different understandings of the worst-result principle, that each contributes to the general argument. Montesquieu’s crucial insight concerns the separation of powers to prevent the state from collapsing into despotism. Judith (...) Shklar shows that ‘damage control’ needs to be constantly performed so as to minimize chances of governmental brutality. Roberto Unger points at the importance of encouraging citizens’ involvement in the political process to safeguard freedom. I finally argue, in the light of historical evidence, that it would be unreasonable to think that the task of preventing tyranny can be effectively performed in the absence of courts entrusted with checking powers.

The ipsilesional arm of stroke patients often has functionally limiting deficits in motor control and dexterity that depend on the side of the brain that is lesioned and that increase with the severity of paretic arm impairment. However, remediation of the ipsilesional arm has yet to be integrated into the usual standard of care for upper limb rehabilitation in stroke, largely due to a lack of translational research examining the effects of ipsilesional-arm intervention. We now ask whether ipsilesional-arm training, tailored (...) to the hemisphere-specific nature of ipsilesional-arm motor deficits in participants with moderate to severe contralesional paresis, improves ipsilesional arm performance and generalizes to improve functional independence. We assessed the effects of this intervention on ipsilesional arm unilateral performance [Jebsen–Taylor Hand Function Test ], ipsilesional grip strength, contralesional arm impairment level [Fugl–Meyer Assessment ], and functional independence [Functional independence measure ]. Intervention occurred over a 3 week period for 1.5 h/session, three times each week. All sessions included virtual reality tasks that targeted the specific motor control deficits associated with either left or right hemisphere damage, followed by graded dexterity training in real-world tasks. We also exposed participants to 3 weeks of sham training to control for the non-specific effects of therapy visits and interactions. We conducted five test-sessions: two pre-tests and three post-tests. Our results indicate substantial improvements in the less-impaired arm performance, without detriment to the paretic arm that transferred to improved functional independence in all three posttests, indicating durability of training effects for at least 3 weeks. We provide evidence for establishing the basis of a rehabilitation approach that includes evaluation and remediation of the ipsilesional arm in moderately to severely impaired stroke survivors. This study was originally a crossover design; however, we were unable to complete the second arm of the study due to the COVID-19 pandemic. We report the results from the first arm of the planned design as a longitudinal study. (shrink)

Although scholars have often settled upon 1686 as the year in which the central elements of Leibniz’s philosophy first appear in systematic form, certain of his positions appear to have been firmly in place at least ten years earlier. Papers written in 1676 reveal that Leibniz had already by that time established the fundamental feature of his single-substance metaphysics: the insubstantiality of matter. As he defines it, matter is a mode, but a mode of peculiar status, a sort of “top (...) mode,” which, together with change, is requisite to the existence of any other modes, or “things.” Things for Leibniz include all bodies and their qualities, and in some places also appear to include minds, although Leibniz for religious reasons equivocates here, and wants to resist. Nevertheless, Leibniz’s desire to move toward a version of the Aristotelian notion of matter as the principle of individuation is clearly in evidence as he works to set out a view which can accommodate mechanistic physics while avoiding the perceived atheistic threat inherent in both Cartesian dualism and Spinozistic monism.

What is wrong with government whistleblowing and when can it be justified? In my view, ‘government whistleblowing’, i.e., the unauthorized acquisition and disclosure of classified information about the state or government, is a form of ‘political vigilantism’, which involves transgressing the boundaries around state secrets, for the purpose of challenging the allocation or use of power. It may nonetheless be justified when it is suitably constrained and exposes some information that the public ought to know and deliberate about. Government whistleblowing (...) should then be viewed, along the lines of civil disobedience, as a collective cognition- and legitimacy-enhancing device. (shrink)

Certain anthropological narratives of South Africa's Eastern Cape province, such as Monica Hunter's 1936 Reaction to Conquest and Philip Mayer's 1963 Townsmen or Tribesmen, persist as potent referential 'bodies of knowledge'. By laying down the coordinates of Black rural and urban experience, such studies continue to animate concepts of tradition and modernity, effectively conjuring up notions of 'the border', both literally and metaphorically. Encountering Pauline Ingle's photographic collection amidst these circuits of knowledge and ways of seeing is to recognise that (...) it is both unusual and exceptional. It is a collection of over 4000 images that are not only located in a rural area but also covers a sustained time period, corresponding to the period of formal apartheid. The concept of the rural is amplified in the collection, positioning it as a site of development, as the 'not yet modern', in which subjects are figured both in class hierarchies and in relation to Daniel Morolong's urban photographs in and around East London in the 1950s. Employing the theory of social acts enables a re-contemplation of the subject, and a reading of the social that suggests a set of possibilities and futures beyond what currently constitutes the rural and the urban; and upturns the disciplinary optics that condition the predominating ethnographies and historiographies of the Eastern Cape.

In the 1980s, the archaeologist Merrick Posnansky implored Africa-trained scholars to investigate the Caribbean and use their training to reframe the construction of the African diasporic experience. This paper is based on research that responded to Posnansky’s challenge. Employing archaeology, community-based fieldwork, oral traditions, gender analysis, and archival sources on both sides of the Atlantic, the paper explores the history of African metallurgy, including the author’s personal research experiences in West Africa and the Caribbean. It argues for incorporating the knowledge (...) and skills of African people into a global history of iron technology. It demonstrates how the spatial and social characteristics of iron smelting and refinement have implications for the unfolding of late eighteenth-century forging in Jamaica and industrial growth in other parts of the Atlantic world. While ideas and knowledge operated in the meanings and metaphors found within both material and unseen realms, the eventual reconceptualization of this intertwined past must remain grounded in claims that can be supported by evidence. Connecting kitchens and crucibles, the study argues for an extended family of technological history. Just as understanding the global history of iron production requires attention to Africa, the inverse is simultaneously true: Africa and its history are firmly integrated in global history, including the history of the industrial revolution.

Quelles sont nos responsabilités face à l’injustice ? Les philosophes considèrent généralement que les citoyens d’un État globalement juste doivent obéir à la loi, même lorsqu’elle est injuste, quitte à employer exceptionnellement la désobéissance civile pour protester. Les militants quant à eux, qu’ils luttent pour les droits civiques, contre les violences faites aux femmes ou pour le climat, jugent souvent que l’obligation première est résister à l’injustice.

In this paper, I argue that the principle of fairness can license both a duty of fair play, which is used to ground a moral duty to obey the law in just or nearly just societies, and a duty of resistance to unfair and unjust social schemes. The first part of the paper analyzes fairness’ demands on participants in mutually beneficial schemes of coordination, and its implications in the face of injustice. Not only fairness does not require complying with unfair (...) and unjust social schemes, but it also prohibits benefiting from such schemes. I use the case of racial segregation in the U.S. to illustrate this latter argument, and consider some objections to my investigation, given the availability and straightforwardness of justice. The second part of the paper elaborates the argument for the duty to resist. The Radical Reform argument first establishes, by elimination of the alternatives (exit and restitution), that the principal way for citizens to cease benefiting from an unfair and unjust social scheme is to radically reform it. The Resistance Argument then shows that resistance is crucial to bring about reform, so that one ought to resist unfair and unjust schemes from which one benefits. Next, I offer two arguments for collective resistance and political solidarity, one based on empirical considerations and the other based on fairness. Finally, I consider the costs of the resistance efforts which fairness may require. (shrink)
