Rips et al. claim that the principles underlying the structure of natural numbers cannot be inferred from interactions with the physical world. However, in their target article they failed to consider an important source of interaction: finger counting. Here, we show that finger counting satisfies all the conditions required for allowing the concept of numbers to emerge from sensorimotor experience through a bottom-up process.

With his massive redeployment hypothesis (MRH), Anderson claims that novel cognitive functions are likely to rely on pre-existing circuits already possessing suitable resources. Here, we put forward recent findings from studies in numerical cognition in order to show that the role of sensorimotor experience in the ontogenetical development of a new function has been largely underestimated in Anderson's proposal.

Despite a growing body of literature focused on understanding experiences of workplace dignity, attention has centered almost exclusively on employees with lower-level jobs. As a result, little is known about how workplace dignity and indignity are experienced by employees with middle- and upper-level jobs and how their experiences differ from those with lower-level jobs. We address these absences by interviewing employees from a diversity of lower-, middle-, and upper-level jobs about their experiences of indignity at work. We outline common dignity (...) threats, along with typical emotional responses and recourses employees use at each level. We find lower-level employees experience chronic dignity threats from being disrespected, devalued, demeaned, and dehumanized, to which their most typical response is endurance. Middle-level employees experience periodic dignity threats due to undermining of their work, confidence, and reputation. For them, the typical response is strategizing. Finally, on the rare occasions upper-level employees experience dignity threats, it usually is due to a disregard of their special expertise or denial of special rights, to which they respond by rising above.

For 15 years, former assistant football coach Jerry Sandusky used his Penn State University perquisites to lure young and fatherless boys by offering them special access to one of the most revered football programs in the country. He repeatedly used the football locker room as a space to groom, molest, and rape his victims. In February 2001, an eye-witness alerted Penn State’s top leaders that Sandusky was caught sexually assaulting a young boy in the showers. Instead of taking swift action (...) against Sandusky, leaders began a cover-up that is considered one of the worst scandals in sports history. While public outcry has focused on the leaders’ silence, we focus on the talk that occurred within the organization by key personnel. Drawing from court documents and internal investigative reports, we examine two euphemism clusters that unfolded in the scandal. The first cluster comprises reporting euphemisms, in which personnel used coded language to report the assault up the chain of command. The second cluster comprises responding euphemisms, in which Penn State’s top leaders relied on an innocuous, but patently false, interpretation of earlier euphemisms as a decision-making framework to chart their course of action. We use this case to demonstrate how euphemistic language impairs ethical decision-making, particularly by framing meaning and visibility of acts, encouraging mindless processing of moral considerations, and providing a shield against psychological and material consequences. Further, we argue that euphemism may serve as a disguised retort to critical upward communication in organizations. (shrink)

When the language-dominant hemisphere is damaged by a focal lesion, the brain may reorganize the language network through functional and structural changes known as adaptive plasticity. Adaptive plasticity is documented for triggers including ischemic, tumoral, and epileptic focal lesions, with effects in clinical practice. Many questions remain regarding language plasticity. Different lesions may induce different patterns of reorganization depending on pathologic features, location in the brain, and timing of onset. Neuroimaging provides insights into language plasticity due to its non-invasiveness, ability (...) to image the whole brain, and large-scale implementation. This review provides an overview of language plasticity on MRI with insights for patient care. First, we describe the structural and functional language network as depicted by neuroimaging. Second, we explore language reorganization triggered by stroke, brain tumors, and epileptic lesions and analyze applications in clinical diagnosis and treatment planning. By comparing different focal lesions, we investigate determinants of language plasticity including lesion location and timing of onset, longitudinal evolution of reorganization, and the relationship between structural and functional changes.

Supernumerary robotic limbs are innovative devices in the field of wearable robotics which can provide humans with unprecedented sensorimotor abilities. However, scholars have raised awareness of the ethical issues that would arise from the large adoption of technologies for human augmentation in society. Most negative attitudes towards such technologies seem to rely on an allegedly clear distinction between therapy and enhancement in the use of technological devices. Based on such distinction, people tend to accept technologies when used for therapeutic purposes (...) (e.g., prostheses), but tend to raise issues when similar devices are used for upgrading a physical or cognitive ability (e.g., supernumerary robotics limbs). However, as many scholars have pointed out, the distinction between therapy and enhancement might be theoretically flawed. In this paper, we present an alternative approach to the ethics of supernumerary limbs which is based on two related claims. First, we propose to conceive supernumerary limbs as tools that necessarily modify our psychological and bodily identity. At the same time, we stress that such a modification is not ethically bad in itself; on the contrary, it drives human interaction with the environment. Second, by comparing our view with the extended mind thesis, we claim that the mediation through tools is crucial for the formation of novel meanings and skills that constitute human interaction with the world. We will relate the latter claim to enactivism as a helpful theoretical perspective to frame issues related to artificial limbs and, more in general, to technologies for augmentation. Based on this approach, we finally sketch some suggestions for future directions in the ethics of supernumerary limbs. (shrink)

In 2010, a cluster of suicides at the electronics manufacturing giant Foxconn Technology Group sparked worldwide outcry about working conditions at its factories in China. Within a few short months, 14 young migrant workers jumped to their deaths from buildings on the Foxconn campus, an all-encompassing compound where they had worked, eaten, and slept. Even though the language of workplace dignity was invoked in official responses from Foxconn and its business partner Apple, neither of these parties directly examined workers’ dignity (...) in their ensuing audits. Based on our analysis of media accounts of life at Foxconn, we argue that its total institution structure imposed unique indignities on its workers that both raised questions of their self-respect and self-worth, as well as gave rise to multiple episodes of disrespectful communication. We interpret our findings in light of the larger cultural context and meanings of work in China to understand more fully the experience of dignity of Foxconn’s migrant workforce. (shrink)

We invoke the ideal of tolerance in response to conflict, but what does it mean to answer conflict with a call for tolerance? Is tolerance a way of resolving conflicts or a means of sustaining them? Does it transform conflicts into productive tensions, or does it perpetuate underlying power relations? To what extent does tolerance hide its involvement with power and act as a form of depoliticization? Wendy Brown and Rainer Forst debate the uses and misuses of tolerance, an exchange (...) that highlights the fundamental differences in their critical practice despite a number of political similarities. Both scholars address the normative premises, limits, and political implications of various conceptions of tolerance. Brown offers a genealogical critique of contemporary discourses on tolerance in Western liberal societies, focusing on their inherent ties to colonialism and imperialism, and Forst reconstructs an intellectual history of tolerance that attempts to redeem its political virtue in democratic societies. Brown and Forst work from different perspectives and traditions, yet they each remain wary of the subjection and abnegation embodied in toleration discourses, among other issues. The result is a dialogue rich in critical and conceptual reflections on power, justice, discourse, rationality, and identity. (shrink)

Use of videogames (VGs) is almost ubiquitous in preadolescents’ and adolescents’everyday life. One of the most intriguing research topic about positive effects of VG use is about the domain of visuospatial competencies. Previous research show that training with videogames enables children and adolescents to improve their scores in visuospatial tests (such as mental rotation of shapes and cubes), and that such training could overcome gender differences in these domains. Our study aimed at (1) verifying the positive effects of videogame use (...) in the visuospatial domain both for male and female adolescents and preadolescents and (2) verifying whether the visualization style (2D or isometric 3D) of the VG has an influence about the positive effects of gaming. Six measures of visuospatial competency were administered to 318 preadolescents (mean of age = 13.94 years, range 10-18) prior and after a 3-day training with 2D and 3D Tetris. Results indicate that (1) gaming on the whole has slight positive effects both for males and females in enhancing visuospatial competencies, at least in the short term, and (2) it seems that participants who used the videogame with 2D graphics obtained greater improvements in the mental rotation domain while the participants who used the videogame with 3D gobtained greater improvements in the spatial visualization domain. However, a general learning effect between T1 and T2 was measured, which was found regardless of Experimental condition, indicating that the effect of training with videogames can be less relevant than expected.

We present a uniform version of Di Nola Theorem, this enables to embed all MV-algebras of a bounded cardinality in an algebra of functions with values in a single non-standard ultrapower of the real interval [0,1]. This result also implies the existence, for any cardinal α, of a single MV-algebra in which all infinite MV-algebras of cardinality at most α embed. Recasting the above construction with iterated ultrapowers, we show how to construct such an algebra of values in a definable (...) way, thus providing a sort of “canonical” set of values for the functional representation.

Weit mehr, als bisher angenommen, ist Derridas vor genau vierzig Jahren erschienene Grammatologie von religiös inspirierten Impulsen motiviert und von diesen her verständlich. Sie stellt nämlich eine Reaktion auf mediale Entwicklungen dar, die gerade in der Abfassungszeit und gerade in den Augen der „aus dem Buch hervorgegangenen Rasse” der Juden existenzbedrohlich erscheinen konnten. Diese Bedrohung wurde von Derrida mit dem Abendland assoziiert und mit einer Vorwärtsverteidigung beantwortet. Ziel seiner Grammatologie war eine medienphilosophisch reformulierte Metaphysikkritik und ein Angriff auf ein Abendland, (...) von dem die jüdische Tradition ausgenommen bleiben, ja aus dem sie gestärkt hervorgehen sollte. Die Konsequenzen seines Buches reichen bis in die Gegenwart und werfen viel Licht auf heutige postsäkulare Spannungen. (shrink)

We prove that the m -generated free MV-algebra is isomorphic to a quotient of the disjoint union of all the m -generated free MV-algebras. Such a quotient can be seen as the direct limit of a system consisting of all free MV-algebras and special maps between them as morphisms.

In this paper we study the notion of forcing for Łukasiewicz predicate logic (Ł∀, for short), along the lines of Robinson’s forcing in classical model theory. We deal with both finite and infinite forcing. As regard to the former we prove a Generic Model Theorem for Ł∀, while for the latter, we study the generic and existentially complete standard models of Ł∀.

Questo articolo intende brevemente analizzare le caratteristiche che la forma del saggio ha assunto all’interno del pensiero del giovane György Lukács, del primo Walter Benjamin e di Theodor W. Adorno. Per tentare di individuare la specificità dei singoli approcci mi sono concentrato su un singolo punto: la funzione centrale che il saggio acquista entro le più generali relazioni che intercorrono tra particolare e sistema. I risultati sono particolarmente interessanti poiché, a fronte di un sostanziale accordo sulla diagnosi iniziale, i tre (...) autori propongono soluzioni anche diametralmente opposte. A partire infatti dal consenso sull’impossibilità di ignorare la frattura prodottasi tra mondo e totalità, se Lukács si appella alla forma del saggio quale unica possibilità di riconnettere i due poli ormai distanti, risolvendo di conseguenza il particolare nel sistema, Adorno la intende invece come la sola forma adeguata ad esprimere l’insormontabilità della frattura. L’articolo si conclude dunque mostrando come solo il saggismo proprio del platonismo a sfumature messianiche di Benjamin sembri tentare di soddisfare le esigenze di entrambe le parti, l’autonomia del trascendente e la salvazione dell’immanente.

Nel corso dell’ultimo mezzo secolo, le «politiche della memoria» si sono imposte a livello teorico e pratico come una dimensione-chiave di quella costellazione di strumenti non punitivi di riscatto dalle atrocità del passato che siamo abituati ad approssimare attraverso le nozioni di «riparative» o «restorative justice». Tutt’altro che concordi appaiono però a tutt’oggi i giudizi degli studiosi sul più profondo significato politico assunto da questo tipo di misure nello specifico contesto dei processi di transizione alla pace e alla democrazia. Il (...) saggio si propone di ricostruire e discutere le principali linee di sviluppo di questo intenso dibattito, soffermandosi in particolare sul controverso rapporto tra memorie della violenza, giustizia di transizione e _agency_ collettiva che costituisce il tema centrale di questo fascicolo di _Scienza & Politica_.

The 1948 Declaration of Human Rights demanded a collaboration among exponents from around the world. Embodying many different cultural perspectives, it was driven by a like-minded belief in the importance of finding common principles that would be essential for the very survival of civilization. Although an arduous and extensive process, the result was a much sought-after and collective endeavor that would be referenced for decades to come. Motivated by the seventieth anniversary of the 1948 Universal Declaration of Human Rights and (...) enriched by the contributions of eminent scholars, this volume aims to be a reflection on human rights and their universality. The underlying question is whether or not, after seventy years, this document can be considered universal, or better yet, how to define the concept of “universality.” We live in an age in which this notion seems to be guided not so much by the values that the subject intrinsically perceives as good, but rather by the demands of the subject. Universality is thus no longer deduced by something that is objectively given, within the shared praxis. Conversely, what seems to have to be universal is what we want to be valid for everyone. This volume will be of interest to those currently engaged in research or studying in a variety of fields including Philosophy, Politics and Law. (shrink)

The extracellular‐signal regulated kinases 1/2 (ERK or ERKs) are involved in the regulation of important neuronal functions, including neuronal plasticity in normal and pathological conditions. We present findings that support the notion that the kinetics and localization of ERK are intrinsically linked, in that the duration of ERK activation dictates its subcellular compartmentalization and/or trafficking. The latter, in turn, dictates whether ERK‐expressing cells would enter a program of cell death, survival or differentiation. We summarize experimental data showing that chronic activation (...) of ERK plays a role in the mechanisms that trigger neurodegeneration. We also discuss how MKPs, members of the subclass of dual specificity phosphatases, might be the link between ERK kinetics and its subcellular localization.

The discovery of neurogenesis and neural stem cells (NSC) in the adult CNS has overturned a long‐standing and deep‐routed “dogma” in neuroscience, established at the beginning of the 20th century. This dogma lasted for almost 90 years and died hard when NSC were finally isolated from the adult mouse brain. The scepticism in accepting adult neurogenesis has now turned into a rush to find applications to alleviate or cure the devastating diseases that affect the CNS. Here we highlight a number (...) of methodological, technical and conceptual drawbacks responsible for the historical denial of adult neurogenesis. Furthermore, we discuss old and new issues that need to be faced before NSC or endogenous neurogenesis can safely enter into the doctor's bag for therapies.

Current climate change has raised concerns over the fate of the stenothermal Antarctic marine fauna (animals that evolved to live in narrow ranges of cold temperatures). The present paper focuses on Notothenioidei, a taxonomic group that dominates Antarctic fish. Notothenioids evolved in the Southern Ocean over the last 20 million years, providing an example of a marine species flock with unique adaptations to the cold at morphological, physiological and biochemical levels. Their phenotypic modifications are often accompanied by ‘irreversible’ genomic losses (...) or gene amplifications. On a micro‐evolutionary scale, relatively ‘shallow’ genetic variation is observed, on account of past fluctuations in population size, and a significant genetic structure is evident, suggesting low population connectivity. These features suggest that Antarctic fish might have relatively little potential to adapt to global warming, at least at a genetic level. The extent of their phenotypic plasticity, which is evident to some degree, awaits further research. (shrink)
