Despite general agreement that altered reward sensitivity is involved in attention-deficit/hyperactivity disorder (ADHD), a wide range of different alterations has been proposed. We cite work showing abnormal sensitivity to delay of reward, together with abnormal sensitivity to individual instances of reward. We argue that at the cellular level these behavioural characteristics might indicate that dopamine timing is off in children with ADHD.

This ‘editorial perspective’ offers reflection on Marxist theory in the narrow domain of social movements and social-movement studies. It offers a brief survey of international class struggles over the last few decades to situate the discussion. It then focuses on the problem of capitalism for social-movement studies, and the particular issue of capitalist totality. It argues that an expansive, processual, historical and temporal conception of class struggle needs to be at the centre of any adequate Marxist approach to social movements, (...) and shows why and how this is so by delving into some contemporary debates over dominant forms of collective action – strike and riot. It also highlights the dialectical relations between production, reproduction and social reproduction, and how the latest revivals of Marxist feminism might guide us through the morass. Finally, it suggests that struggles across these interrelated domains can be linked through an ‘infrastructure of dissent’. (shrink)

This introduction situates the work of Zavaleta in the field of Bolivian intellectual history, Latin American Studies, and Latin American Marxism. It also explains the objectives of the symposium and the logic underlying its constituent parts.

George Ciccariello-Maher’sWe Created Chávezis the most important book available in English proposing an anti-capitalist framework for understanding the Bolivarian process in contemporary Venezuela, as well as its historical backdrop dating back to 1958. The book contains within it a laudable critique of Eurocentrism and a masterful combination of oral history, ethnography, and theoretical sophistication. It reveals with unusual clarity and insight the multiplicity of popular movements that allowed for Hugo Chávez’s eventual ascension to presidential office in the late 1990s.We Created (...) Chávezhas set a new scholarly bar for social histories of the Bolivarian process and demands serious engagement by Marxists. As a first attempt at such engagement, this paper reveals some critical theoretical and sociological flaws in the text and other areas of analytical imprecision. Divided into theoretical and historical parts, it unpacks some of the strengths and weaknesses by moving from the abstract to the concrete. The intervention begins with concepts – the mutually determining dialectic between Chávez and social movements; ‘the people’; and ‘dual power’. From here, it grounds these concepts, and Ciccariello-Maher’s use of them, in various themes and movements across specific historical periods of Venezuelan political development – the rural guerrillas of the 1960s, the urban guerrillas of the 1970s, the new urban socio-political formations of the 1980s, Afro-Indigenous struggles in the Bolivarian process, and formal and informal working-class transformations since the onset of neoliberalism and its present contestation in the Venezuelan context.

This editorial perspective attempts to explain the recent rise of Jair Bolsonaro to the presidency in Brazil and to characterise, at least in a preliminary fashion, the nature of the new regime one year into Bolsonaro’s rule. The core argument is that Bolsonaro represents a weak and internally-fragmented far-right regime, with unenthusiastic and declining popular support. Dominant sections of international and domestic capital operating in Brazil lent Bolsonaro electoral backing as a last way out of economic and political crisis, but (...) so far, the new government has failed in sufficiently guaranteeing their most important interests and the markets are withdrawing approval. Themes covered include the political paralysis of the new regime, the social bases of Bolsonarismo, the nature of the current state–capital relation, and the role of evangelical Pentecostalism in far-right Brazilian politics today. A biographical portrait of Bolsonaro is provided, alongside a mapping of the dominant factions of the new administration. Finally, an assessment of the economic outlook in Brazil is developed, together with speculation as to the likely political consequences in the short- to medium-term future. (shrink)

This review-essay offers an extended engagement with Fernando Ignacio Leiva’s Latin American Neostructuralism, one of the most important contributions to contemporary Latin-American political economy. It situates Leiva’s critique of neostructuralism against the wider backdrop of Latin America’s contradictory turn to the Left since the late 1990s, and compares the treatments of change in Latin-American capitalism over the course of the twentieth and early twenty-first centuries developed by the schools of classical structuralism, neostructuralism, and neoliberalism. The essay finds that Leiva’s critique (...) of neostructuralism and his explanation for its influence on large segments of the region’s Left is the best work on the topic currently available in English. Leiva systematically demolishes neostructuralism’s claim to be a progressive alternative to neoliberalism. At the same time, it is argued that Leiva’s theoretical framework is compromised by its uncritical adoption of categories from French regulation-theory, and its nostalgia for elements of classical structuralism and its associated development-model of import-substitution industrialisation. Further, it is found that Leiva’s implicit attachment to certain myths propagated by the Marxism of the Second and, especially, Third Internationals regarding the national bourgeoisie’s role in Third-World capitalist development leaves him unduly dogmatic about the necessity, and unduly optimistic about the possibility, of building a progressive stage of capitalism in Latin America today. The same mythologies prevent Leiva from drawing the appropriate conclusions as regards the urgent necessity of rebuilding the socialist project in Latin America and internationally. (shrink)

This article offers an historical-materialist account of the coup in Honduras on 28 June 2009, which ousted democratically elected President Manuel Zelaya. It draws on over two dozen interviews with members of theFrente Nacional de la Resistencia Popular[National Front of Popular Resistance, FNRP], and participation in numerous marches and assemblies over two periods of fieldwork – January 2010, and June–July 2011. The paper steps back in time to provide an historical cartography of the basic material structures of the Honduran economy (...) and its integration into the world market, as well as the geopolitical role it played as a launching pad for Ronald Reagan’s counter-insurgency campaigns against guerrilla forces elsewhere in the region during the 1980s. We show how the defeat of mass guerrilla insurgencies in Guatemala and El Salvador, as well as the triumph over the Sandinista government in Nicaragua by 1990, allowed for the neoliberal pacification of Central America as a whole, including Honduras. We further demonstrate how the centre-leftist Manuel Zelaya, elected to the Honduran presidency in 2006, modestly encroached upon neoliberal orthodoxy and forged geopolitical alliances with left and centre-left governments elsewhere in the region, laying the bases for his violent overthrow. Finally, the paper traces the origins, trajectory, and heterogeneity of the resistance that emerged almost immediately after the coup had been carried out. (shrink)

As COVID-19 and its variants spread across Australia at differing paces and intensity, the country’s response to the risk of infection and contagion revealed an intensification of bordering practices as a form of risk mitigation with disparate impacts on different segments of the Australian community. Australia’s international border was closed for both inbound and outbound travel, with few exceptions, while states and territories, Indigenous communities, and local government areas were subject to a patchwork of varying restrictions. By focusing on borders (...) at various levels, our research traces how the logics of medico-legal bordering have filtered down from the international to the intra-national, and indeed, into hyper-local spaces. This is not just apparent in the COVID-19 moment but in previous pandemics of 1918 to 1919 influenza and smallpox, in which practices of quarantine and lockdowns were both unevenly distributed and implemented on multiple scales of social organization. An interdisciplinary approach between history and law reveals that human movement during pandemic times in Australia has been regulated in a manner that sees mobility as a risk to public health capable of mitigation through the strict enforcement of borders as a technology of both confinement and exclusion.

The coming to office of Jair Bolsonaro in Brazil has brought to the fore the need to understand the rise of the far right and to come to terms with the conflicted legacies of more than a decade of rule under the Workers’ Party. This forum brings together six leading intellectuals from different traditions on the left and introduces their reflections on the contradictions and complexities of the Workers’ Party, the 2008 crisis, the June 2013 protests, the weakness of the (...) Brazilian left, corruption, and on how to characterise Bolsonaro’s regime. Their interventions offer crucial insights that are relevant today not just to Brazil, or even Latin America, but to the politics of the left worldwide. (shrink)

The ‘Bolivarian Revolution’ in Venezuela under Hugo Chávez has reignited debate in Latin America and internationally on the questions of socialism and revolution. This forum brings together six leading intellectuals from different revolutionary traditions and introduces their reflections on class-struggle, the state, imperialism, counter-power, revolutionary parties, community and communes, workplaces, economy, politics, society, culture, race, gender, and the hopes, contradictions, and prospects of ‘twenty-first-century socialism’ in contemporary Venezuela.

Ascidians have evolved alternate modes of development in which the conventional tadpole larva is remodeled or eliminated. Adultation, the precocious development of adult features in the larval head, is caused by superimposing the larval and adult differentiation programs. Caudalization, the addition of muscle cells to the larval tail, is caused by enhancing muscle induction or increasing the number of muscle cell divisions before terminal differentiation. Adultation and caudalization are correlated with increased egg size, suggesting dependence on maternal processes. Anural development, (...) the elimination of the larval stage, is caused by maternal and zygotic events resulting in abbreviation and deletion of larval developmental programs. An example of a maternal change in anural species is the modification of the egg cytoskeleton during oogenesis, whereas a zygotic change may involve altered cell interactions during embryogenesis. Interspecific hybridization experiments suggest that some aspects of anural development may be caused by loss‐of‐function mutations. The dissociation of developmental programs is a key process in changing the mode of development in ascidians. (shrink)

This is the first volume compiling English translations of Leibniz's journal articles on natural philosophy, presenting a selection of 26 articles, only three of which have appeared before in English translation. It also includes in full Leibniz's public controversies with De Catelan, Papin, and Hartsoeker. The articles include work in optics, on the fracture strength of materials, and on motion in a resisting medium, and Leibniz's pioneering applications of his calculus to these issues by construing them as mini-max and inverse (...) tangent problems. Other topics covered by the articles include: criticisms of the Cartesian estimate of motive force and Leibniz's proposal of a different way of estimating force to replace it; a proposed theory of celestial motions and gravitation, and derivation of the inverse square law; challenge problems concerning the isochronous curve and the catenary; a sample of work on gaming theory; and Leibniz's critique of atomism.

Recent studies have shown that some maternal mRNAs are localized in specific cytoplasmic regions of eggs and embryos and are rearranged in concert with the cytoplasmic movements that fix the embryonic axes. The localization and ooplasmic segregation of mRNA molecules may be mediated by their association with specific egg cytoskeletal domains.

What is it like to live with the label “Disability?” NIB editorial staff and narrative symposium editors, Jeffery Bishop and Naomi Sunderland developed a call for stories, which was sent to several list serves, shared with the 1000 Voices Project community and posted on Narrative Inquiry in Bioethics ’ website. The request for personal stories from people who identify with the label “disabled” asked them to: consider how the label “disability” interacts with other aspects of their life in health (...) care settings; does the term “disability” reflect their actual embodied experiences of impairment or does it fail to do justice to their particular experience of impairment; describe the kind of experiences that are possible because of the impairment(s); discuss how the label has affected their “authentic voice”; and many other concepts about what effects the label has on their lives. These authors share deeply personal experiences that will help readers understand their world, challenges, and joys. Thirteen stories are found in the print version of the journal and an additional five supplemental stories are published online only through Project MUSE. The stories are complemented by four commentary articles by Elizabeth R. Schiltz; Lorna Hallahan; Nicole Matthews, Kathleen Ellem, and Lesley Chenoweth; and Jeffery Bishop, Rachelle Barina, and Devan Stahl. These scholars come from the disciplines of law, social work, media studies, medicine, and bioethics from Australia and the United States. Together, the symposium’s storytellers and commentators offer striking and informative insights into the everydayness of living with disabilities. (shrink)

The term “stakeholder capitalism” has become part of our shared business lexicon. This is due in large part to the work of R. Edward Freeman and his collaborators who conceive of stakeholder theory not simply as an approach to ethics in business but also of a new narrative for the ethics of capitalism. We argue that stakeholder thought as it is developed in this literature remains deficient as an ethics of capitalism because it fails to fully appreciate the distinction between (...) business firms as one institution of capitalism and capitalism as an interrelated network of institutions. Failing to appreciate this distinction thwarts any facile movement between the theory's account of the ethics of business, which is concerned with the aims that guide business management, and the ethics of capitalism, which is concerned with how various institutions should be designed as a system with an internal division of moral labor. This difference suggests a prospective way forward for stakeholder theory that focuses more attention on the responsibilities that business firms owe to support the legal and economic institutions of capitalism.

Most computational theories of cognition lack a representation of physiology. Understanding the cognitive effects of compounds present in the environment is important for explaining and predicting changes in cognition and behavior given exposure to toxins, pharmaceuticals, or the deprivation of critical compounds like oxygen. This research integrates physiologically based pharmacokinetic (PBPK) model predictions of caffeine concentrations in blood and tissues with ACT-R's fatigue module to predict the effects of caffeine on fatigue. Mapping between the PBPK model parameters and ACT-R model (...) parameters is informed by the neurophysiological literature and established associations between ACT-R modules and brain regions. The results from three such parameter mappings are explored to explain observed data from sleep-deprived participants performing the psychomotor vigilance test with and without caffeine. Predicted caffeine concentrations in the brain are used to modulate procedural parameters in the fatigue module to explain caffeine's effects on multiple performance metrics. (shrink)

Infinite Paths to Infinite Reality, by Ayon Maharaj, is a book whose significance is highly likely to reverberate throughout the fields of both the philosophy of religion and the study of Indian philosophy for years to come.

ABSTRACT:In this address I argue that different perspectives on the normative foundations of corporate responsibility reflect underlying disagreements about the ideal arrangement of tasks between market and state. I initially recommend that scholars look back to the “division of moral labor” inspired by John Rawls’ seminal work on distributive justice in order to rethink why, and to what extent, corporations take on responsibilities normally within the purview of government. I then examine how this notion is related to recent theoretical work (...) in the field of business ethics. I thereafter turn to provide a brief outline of an alternative view that sees corporations as having responsibilities in so far as markets are sites of delegated oversight over the production of social goods that might otherwise be administered by the state.

Originally published in 1950, this book is one of a series of studies regarding the structure of the British economy which were produced by the National Institute of Economic and Social Research after the Second World War. It was produced in collaboration with a group of leading businessmen, all of whom were concerned in one way or another with the distribution of consumer goods and dissatisfied with the existing state of knowledge about distribution. The study represented a substantial advance in (...) the knowledge of distribution and an important contribution to structural economics. It will remain of value to anyone with an interest in the development of the British economy. (shrink)
