Cognitive Architecture, Concepts, and Introspection: An Information-Theoretic Solution to the Problem of Phenomenal Consciousness

This essay is a sustained attempt to bring new light to some of the perennial problems in philosophy of mind surrounding phenomenal consciousness and introspection through developing an account of sensory and phenomenal concepts. Building on the information-theoretic framework of Dretske (1981), we present an informational psychosemantics as it applies to what we call sensory concepts, concepts that apply, roughly, to so-called secondary qualities of objects. We show that these concepts have a special informational character and semantic structure that closely tie them to the brain states realizing conscious qualitative experiences. We then develop an account of introspection which exploits this special nature of sensory concepts. The result is a new class of concepts, which, following recent terminology, we call phenomenal concepts: these concepts refer to phenomenal experience itself and are the vehicles used in introspection. On our account, the connection between sensory and phenomenal concepts is very tight: it consists in different semantic uses of the same cognitive structures underlying the sensory concepts, such as the concept of red. Contrary to widespread opinion, we show that information theory contains all the resources to satisfy internalist intuitions about phenomenal consciousness, while not offending externalist ones. A consequence of this account is that it explains and predicts the so-called conceivability arguments against physicalism on the basis of the special nature of sensory and phenomenal concepts. Thus we not only show why physicalism is not threatened by such arguments, but also demonstrate its strength in virtue of its ability to predict and explain away such arguments in a principled way. However, we take the main contribution of this work to be what it provides in addition to a response to those conceivability arguments, namely, a substantive account of the interface between sensory and conceptual systems and the mechanisms of introspection as based on the special nature of the information flow between them

Nudge plus: incorporating reflection into behavioural public policy

The authors of this paper outline a modified version of the behaviour change technique called ‘nudge plus’, which incorporates an element of reflection as part of the delivery of a nudge. Nudge plus builds on recent work advocating educative nudges and boosts. The authors claim that a hybrid nudge–think strategy can be a useful additional way to design pro-social interventions; combining a colour-coded ‘traffic lighting’ nudge with a salience-building ‘information plus’, for example, can increase the uptake of the nudge by agents, especially by those who might unconsciously ignore the visual cue implied by the colour coding of the nudge alone. Such a process is more plausible than the nudge-only strategies because combinations of nudges with reflective strategies are not only more liberty-preserving to the agent, but they can also generate stronger and persistent one-off effects. The authors suggest three key mechanisms of operationalising this nudge-plus: the plus could either come before and after (sequentially) or along with (simultaneous to) the nudge. Depending on when the ‘plus’ is administered with the nudge, it could embody various kinds of reflection; a plus that precedes a nudge, for instance, involves reflecting on the construct of the nudge or on the alternatives competing for availability to the decision-making agent. Finally, the authors compare the mechanistic scheme of the nudge-plus against that of the behavioural change tools that are currently available, namely classic nudges and boosts

Steps to an Ecology of Networked Knowledge and Innovation: Enabling new forms of collaboration among sciences, engineering, arts, and design

SEAD network White Papers ReportThe final White Papers (posted at http://seadnetwork.wordpress.com/white-paper- abstracts/final-white-papers/) represent a spectrum of interests in advocating for transdisciplinarity among arts, sciences, and technologies. All authors submitted plans of action and identified stakeholders they perceived as instrumental in carrying out such plans. The individual efforts led to an international scope. One of the important characteristics of this collection is that the papers do not represent a collective aim toward an explicit initiative. Rather, they offer a broad array of views on barriers faced and prospective solutions. In summary, the collected White Papers and associated Meta- analyses began as an effort to take the pulse of the SEAD community as broadly as possible. The ideas they generated provide a fruitful basis for gauging trends and challenges in facilitating the growth of the network and implementing future SEAD initiatives.National Science Foundation Grant No.1142510.

The knowing ear : an Australian test of universal claims about the semantic structure of sensory verbs and their extension into the domain of cognition

In this paper we test previous claims concerning the universality of patterns of polysemy and semantic change in perception verbs. Implicit in such claims are two elements: firstly, that the sharing of two related senses A and B by a given form is cross-linguistically widespread, and matched by a complementary lack of some rival polysemy, and secondly that the explanation for the ubiquity of a given pattern of polysemy is ultimately rooted in our shared human cognitive make-up. However, in comparison to the vigorous testing of claimed universals that has occurred in phonology, syntax and even basic lexical meaning, there has been little attempt to test proposed universals of semantic extension against a detailed areal study of non-European languages. To address this problem we examine a broad range of Australian languages to evaluate two hypothesized universals: one by Viberg (1984), concerning patterns of semantic extension across sensory modalities within the domain of perception verbs (i .e. intra-field extensions), and the other by Sweetser (1990), concerning the mapping of perception to cognition (i.e. trans-field extensions). Testing against the Australian data allows one claimed universal to survive, but demolishes the other, even though both assign primacy to vision among the senses

AAPOR Report on Big Data

In recent years we have seen an increase in the amount of statistics in society describing different phenomena based on so called Big Data. The term Big Data is used for a variety of data as explained in the report, many of them characterized not just by their large volume, but also by their variety and velocity, the organic way in which they are created, and the new types of processes needed to analyze them and make inference from them. The change in the nature of the new types of data, their availability, the way in which they are collected, and disseminated are fundamental. The change constitutes a paradigm shift for survey research.There is a great potential in Big Data but there are some fundamental challenges that have to be resolved before its full potential can be realized. In this report we give examples of different types of Big Data and their potential for survey research. We also describe the Big Data process and discuss its main challenges

Uneven and combined development: modernity, modernism, revolution

Trotsky’s theory of Uneven and Combined Development was born out of his experience of the Russian Revolution. To mark the centenary of the revolution, we are publishing a series of five pieces by Neil Davidson that explore the theory’s wider contribution to how we understand capitalist modernity. These articles show how ideas that began life in the revolution continue to inspire new ways of grasping the world, and that we are very much engaging in a living 21st century world when reflecting on the previous century. The series published here are extracts of his forthcoming book Violating all the Laws of History that will be published in the Haymarket Historical Materialism series in 2018

The future of evapotranspiration : global requirements for ecosystem functioning, carbon and climate feedbacks, agricultural management, and water resources

The fate of the terrestrial biosphere is highly uncertain given recent and projected changes in climate. This is especially acute for impacts associated with changes in drought frequency and intensity on the distribution and timing of water availability. The development of effective adaptation strategies for these emerging threats to food and water security are compromised by limitations in our understanding of how natural and managed ecosystems are responding to changing hydrological and climatological regimes. This information gap is exacerbated by insufficient monitoring capabilities from local to global scales. Here, we describe how evapotranspiration (ET) represents the key variable in linking ecosystem functioning, carbon and climate feedbacks, agricultural management, and water resources, and highlight both the outstanding science and applications questions and the actions, especially from a space-based perspective, necessary to advance them

Democracy, development and the executive presidency in Sri Lanka

This paper examines the developmental causes and consequences of the shift from a parliamentary to a semi-presidential system in Sri Lanka in 1978, examining its provenance, rationale, and its unfolding trajectory. drawing on a wide range of sources, it set out an argument that the executive presidency was born out of an elite impulse to create a more stable, centralised political structure to resist the welfarist electoral pressures that had taken hold in the post-independence period, and to pursue a market-driven model of economic growth. This strategy succeeded in its early years 197801993, when presidents retained legislative control, maintained a strong personal commitment to market reforms, and cultivated alternative sources of legitimacy. In the absence of these factors, the presidency slipped into crisis over 1994-2004 as resistance to elite-led projects of state reform mounted and as the president lost control of the legislature. Since 2005 the presidency has regained its power, but at the cost of abandoning its original rationale and function as a means to recalibrate the elite/mass power relations to facilitate elite-led reform agendas
