Introduction
Jerry Fodor, by common agreement, is one of the world’s leading philosophers. At the
forefront of the cognitive revolution since the 1960s, his work has determined much of
the research agenda in the philosophy of mind and the philosophy of psychology for
well over 40 years. This special issue dedicated to his work is intended both as a tribute
to Fodor and as a contribution to the fruitful debates that his work has generated.
One philosophical thesis that has dominated Fodor’s work since the 1960s is realism
about the mental. Are there really mental states, events and processes? From his
first book, Psychological Explanation (1968), onwards, Fodor has always answered
this question with a resolute yes. From his early rejection of Wittgensteinian and
behaviourist conceptions of the mind, to his later disputes with philosophers of mind
of the elminativist ilk, he has always been opposed to views that try to explain
away mental phenomena. On his view, there are minds, and minds can change the
world
Three Flavor Neutrino Oscillations in Matter: Flavor Diagonal Potentials, the Adiabatic Basis and the CP phase
We discuss the three neutrino flavor evolution problem with general,
flavor-diagonal, matter potentials and a fully parameterized mixing matrix that
includes CP violation, and derive expressions for the eigenvalues, mixing
angles and phases. We demonstrate that, in the limit that the mu and tau
potentials are equal, the eigenvalues and matter mixing angles theta_12 and
theta_13 are independent of the CP phase, although theta_23 does have CP
dependence. Since we are interested in developing a framework that can be used
for S matrix calculations of neutrino flavor transformation, it is useful to
work in a basis that contains only off-diagonal entries in the Hamiltonian. We
derive the "non-adiabaticity" parameters that appear in the Hamiltonian in this
basis. We then introduce the neutrino S matrix, derive its evolution equation
and the integral solution. We find that this new Hamiltonian, and therefore the
S matrix, in the limit that the mu and tau neutrino potentials are the same, is
independent of both theta_23 and the CP violating phase. In this limit, any CP
violation in the flavor basis can only be introduced via the rotation matrices,
and so effects which derive from the CP phase are then straightforward to
determine. We show explicitly that the electron neutrino and electron
antineutrino survival probability is independent of the CP phase in this limit.
Conversely, if the CP phase is nonzero and mu and tau matter potentials are not
equal, then the electron neutrino survival probability cannot be independent of
the CP phase
NOC turbulence glider deployment report for the Liverpool Bay Coastal Observatory, June 2011 deployment
A summary of the NOC Liverpool turbulence glider deployment that occurred between Tuesday 28th June and Monday 4th July 2011 is provided in this document. The general objective of the deployment was to hold the glider on station at a nominal GPS location of 53o 48”N, -4o 00”W to provide a series of glider based turbulence probe and CTD data
profiles. These profiles were initiated when the glider reached a nominal depth of 40 metres and continued until the glider approached the sea surface. The glider deployment site was selected to be away from the influence of fresh water influx into the Liverpool Bay and in a
position that avoids scheduled shipping routes. The recorded glider data was compared with a seabed instrumentation frame that was deployed at the same nominal location. The instrumentation frame had a Seabird CTD and a 5 axis upward measuring ADCP with a vertical turbulence measurement capability installed. During the glider deployment cruise reference water samples and independent CTD measurements were collected for deployed instrumentation and glider sensor calibration purpose
On the Matter of Robot Minds
The view that phenomenally conscious robots are on the horizon often rests on a certain philosophical view about consciousness, one we call “nomological behaviorism.” The view entails that, as a matter of nomological necessity, if a robot had exactly the same patterns of dispositions to peripheral behavior as a phenomenally conscious being, then the robot would be phenomenally conscious; indeed it would have all and only the states of phenomenal consciousness that the phenomenally conscious being in question has. We experimentally investigate whether the folk think that certain (hypothetical) robots made of silicon and steel would have the same conscious states as certain familiar biological beings with the same patterns of dispositions to peripheral behavior as the robots. Our findings provide evidence that the folk largely reject the view that silicon-based robots would have the sensations that they, the folk, attribute to the biological beings in question
The innovative capacity of voluntary organisations and the provision of public services: A longitudinal approach
The prior history of voluntary and community organisations (VCOs) as pioneers of public services during the late nineteenth and early twentieth century has lead to reification of the innovativeness of these organisations. Is this reification justified – are VCOs inherently innovative, or is innovation contingent on other factors? This paper reports on a longitudinal study of this capacity conducted over 1994 – 2006. This study finds that the innovative capacity of VCOs is in fact not an inherent capacity but rather is contingent upon the public policy framework that privileges innovation above other activity of VCOs. The implications of this for theory, policy and practice are considered
The Philadelphia story: a new forecasting model
Several years ago, the Philadelphia Fed developed a small forecasting model for each of the three states in the Third Federal Reserve DistrictCPennsylvania, New Jersey, and Delaware. This article introduces a similar model that forecasts major economic variables for the Philadelphia metropolitan area and the city of Philadelphia. Read this article and find out what the model predicts for the metro area and the cityForecasting ; Philadelphia (Pa.)
Implementable Wireless Access for B3G Networks - III: Complexity Reducing Transceiver Structures
This article presents a comprehensive overview of some of the research conducted within Mobile VCE’s Core Wireless Access Research Programme,1 a key focus of which has naturally been on MIMO transceivers. The series of articles offers a coherent view of how the work was structured and comprises a compilation of material that has been presented in detail elsewhere (see references within the article). In this article MIMO channel measurements, analysis, and modeling, which were presented previously in the first article in this series of four, are utilized to develop compact and distributed antenna arrays. Parallel activities led to research into low-complexity MIMO single-user spacetime coding techniques, as well as SISO and MIMO multi-user CDMA-based transceivers for B3G systems. As well as feeding into the industry’s in-house research program, significant extensions of this work are now in hand, within Mobile VCE’s own core activity, aiming toward securing major improvements in delivery efficiency in future wireless systems through crosslayer operation
Mortality post inpatient alcohol detoxification: a descriptive case series
<br>Background: Individuals with alcohol dependence often die prematurely. Scotland in particular has high rates of alcohol misuse compared to the rest of the UK and Europe. Although there is some evidence that rates of alcoholrelated harm and alcohol-related deaths are reducing in Europe, there is little evidence of this trend occurring in Scotland. Inpatient detoxification is an important, but expensive, option in the management of alcohol dependence. Little work has been done with regard possible clinical characteristics associated with mortality post discharge in this cohort of patients.</br>
<br>Methods: Retrospective electronic records were used to identify patients admitted electively for alcohol detoxification into a psychiatric ward in a district general hospital under the care of a single consultant addiction psychiatrist between 1/1/05 and 31/12/07 inclusively. Demographic and clinical factors were recorded. 5-year mortality data was obtained by linkage to the National Records of Scotland.</br>
<br>Results: 25.2% of patients admitted for elective alcohol detoxification died during the 5-year follow up period. 42.9% of deaths (n=12) were due to alcoholic liver disease, one death (3.6%) was of undetermined intent. A higher proportion of the deceased cohort was likely to have continued disulfiram (93% vs. 80%) and acamprosate (81% vs. 60%) than those surviving. There was no statistically significant difference in survival between individuals on medication and those not on medications in our cohort. The average consumption of units of alcohol per week in the deceased cohort was significantly higher than that calculated for the surviving cohort (298.8 units vs. 233.3 units p=0.0137).</br>
<br>Conclusion: Inpatient detoxification was associated with significant mortality at 5-year follow up post- discharge. The majority of deaths were due to liver disease while deaths due to accidents and of undetermined intent were relatively infrequent. Increased education and practical strategies such as “space and pace” aimed both at an individual and societal level to reduce alcohol consumption may help to reduce mortality associated with alcohol dependence post inpatient detoxification.</br>
