SUPER SIZE SPAIN? A CROSS-SECTIONAL AND QUASI-COHORT TREND ANALYSIS OF ADULT OVERWEIGHT AND OBESITY IN AN ACCELERATED TRANSITION COUNTRY
Authors: CÁMARA ANTONIO D. , SPIJKER JEROEN J. A. 
Published: January 2010

SummaryExcess weight is becoming widespread in Spain due to changes in nutritional habits and lifestyles. Previous studies on this issue have focused on specific Spanish regions, subpopulations or relatively short time spans. This study analysed sex, age and cohort trends in the prevalence of adult overweight and obesity over the last two decades by applying a demographic methodology. Data came from the Spanish National Health Surveys that were held between 1987 and 2006. The respondent's demographic characteristics and self-reported height and weight were aggregated to a single dataset in order to analyse changes in weight and BMI by age and sex, over time and within and between quasi birth-cohorts. After correcting for sample bias and coding errors a total sample of about 100,000 subjects aged 20–79 was obtained. The results show that between 1987 and 2006 adult males and females increased their average weight by 8.2% and 2.8%, respectively. While among younger adults this is partly explained by height increases, prevalence in excess weight increased among 50- to 79-year-old males. Persons of the same 10-year age group but of a more recent 10-year quasi birth-cohort had a BMI that was 0.2–0.8 points higher. BMI increases were lower for women and mainly affected 60–79 year olds. In fact, even decreases were observed for 40- to 49 and 50- to 59-year-old women. Potential explanatory factors are discussed.
Alfvén simple waves
Authors: WEBB G. M. , ZANK G. P. , BURROWS R. H. , RATKIEWICZ R. E. 
Published: February 2010

AbstractMulti-dimensional Alfvén simple waves in magnetohydrodynamics (MHD) are investigated using Boillat's formalism. For simple wave solutions, all physical variables (the gas density, pressure, fluid velocity, entropy, and magnetic field induction in the MHD case) depend on a single phase function ϕ, which is a function of the space and time variables. The simple wave ansatz requires that the wave normal and the normal speed of the wave front depend only on the phase function ϕ. This leads to an implicit equation for the phase function and a generalization of the concept of a plane wave. We obtain examples of Alfvén simple waves, based on the right eigenvector solutions for the Alfvén mode. The Alfvén mode solutions have six integrals, namely that the entropy, density, magnetic pressure, and the group velocity (the sum of the Alfvén and fluid velocity) are constant throughout the wave. The eigenequations require that the rate of change of the magnetic induction B with ϕ throughout the wave is perpendicular to both the wave normal n and B. Methods to construct simple wave solutions based on specifying either a solution ansatz for n(ϕ) or B(ϕ) are developed.
Nicholas Medtner: An Appreciation
Authors: Alexander Arthur 
Published: February 2010

In the long history of art there are those, who, living before their time, have been mainly ignored or derided. Others, like Dussek, have all unknowing, anticipated something of the composers to come. Yet another, like Mozart (the least original Great Master), by adding to and enriching the music of his age, has brought it to a noble climax.Conversely, there are others, who, fancying they can ignore the past, experiment with artificial formulae in a vain endeavour to by-pass evolution.
Some Observations on Bartók's Third Piano Concerto
Authors: Suchoff Benjamin 
Published: February 2010

In the correspondence between Bartók and his publisher, Ralph Hawkes, a letter to the composer, dated 22 August 1940, contains what is apparently the first mention of the Third Piano Concerto:I do not know whether you have developed any ideas for new works during the last few months, quite possibly not, but I would like to remind you of your promise of the orchestral version of the Two Pianos and Percussion work, also to advise you that I shall expect the Third Piano Concerto by the summer of 1941. My reason for saying this is that you will be wanted as soloist with this work for the New York Philharmonic during its Centennial Season 1941–42.
Khargūshī,Tahdhīb al-asrār
Authors: Melchert Christopher 
Published: January 2010

AbstractKhargushi (d. Nishapur, 407/1016?),Tahdhīb al-asrār, is a fairly large collection of sayings in the renunciant/Sufi tradition, comprising over twice as many items as Sarrāj,al-Lumaʿ and Sulamī,Ṭabaqāt al-sufiyya. A first printed edition appeared in 1999. Examination of theTahdhībconfirms that Khargūshī was Shāfiʿi in law, Ashʿari in theology, but mainly a preacher devoted to piety. It also tends to confirm current common wisdom about the history of Sufism: that it developed out of the earlier renunciant tradition, that Malāmatism was a distinctive Nishapuran school of mystical piety with such affinities to Baghdadi Sufism as make it easily assimilable to it, and that Khargūshī's time was still that of the teaching master, the training master not appearing till half a century later. Its similarities to Sarrāj,al-Lumaʿand Abū Nuʿaym,Ḥilyat al-awliyā’make both of those appear more mainstream than has sometimes been feared.
Social Assistance and Territorial Justice: The Example of Single Payments
Authors: Walker Robert , Lawton Dorothy 
Published: January 2010

ABSTRACTSocial assistance in many countries is administered locally. Centralised, uniform schemes, such as those which operate in Britain are often assumed to guarantee, or at least to enhance, territorial equity, that is the equal treatment of individuals with identical needs irrespective of where they live. This assumption is examined with respect to the system of single payments—lump sum payments to meet exceptional needs—which existed prior to the 1988 social security reforms. Although much of the geographic variation in the volume of awards which used to exist is explicable in terms of variations in the level of need, territorial inequity is demonstrated to have occurred in what was a nationally administered and closely regulated scheme. The reasons for the inequity seem in part to have been due to variations in office work flow and working practices, welfare rights activity and unidentified processes linked in some way to the regional administrative structure of DHSS.
Précis of Gallistel'sThe organization of action: A new synthesis
Authors: Gallistel C. R. 
Published: February 2010

AbstractThe book describes three elementary units of action – the reflex, the oscillator, and the servomechanism – and the principles by which they are combined to make complex units. The combining of elementary units to make complex units gives behavior and the neural circuitry underlying behavior a hierarchical structure. Circuits at higher levels govern the operation of lower circuits by selective potentiation and depotentiation: by regulating the potential for operation in lower circuits – raising the potential for some and lowering it for others – a higher unit establishes the overall pattern to be exhibited in the combined operations of the lower units, while leaving it to the lower units to determine the details of the implementation of this pattern. A theory of motivation of the kind long championed by ethologists and physiological psychologists grows out of the notion of the selective potentiation and depotentiation of hierarchically structured units of behavior. The question then becomes how this conception of motivation may be integrated with a conception of a learned representation of the world to yield a theory of how animals produce novel motivated behavioral sequences based on learned representations. The representation of space, which is central to the behavior of organisms at least as lowly as the digger wasp, is a promising domain for the investigation of this question. Another promising area is the representation of skilled movements, such as handwriting. A number of issues in cognitive and developmental psychology are illumined by this theory about the organization of action. Among these are the degrees-of-freedom problem, the role of practice in development and in the learning of skilled action, and the role of mental rotation of spatial representations.
Intentional systems in cognitive ethology: The “Panglossian paradigm” defended
Authors: Dennett Daniel C. 
Published: February 2010

AbstractEthologists and others studying animal behavior in a “cognitive” spirit are in need of a descriptive language and method that are neither anachronistically bound by behaviorist scruples nor prematurely committed toparticular“information-processing models.” Just such an interim descriptive method can be found inintentional system theory. The use of intentional system theory is illustrated with the case of the apparently communicative behavior of vervet monkeys. A way of using the theory to generate data - including usable, testable “anecdotal” data - is sketched. The underlying assumptions of this approach can be seen to ally it directly with “adaptationist” theorizing in evolutionary biology, which has recently come under attack from Stephen Gould and Richard Lewontin, who castigate it as the “Panglossian paradigm.” Their arguments, which are strongly analogous to B. F, Skinner's arguments against “mentalism,” point to certain pitfalls that attend the careless exercise of such “Panglossian” thinking (and rival varieties of thinking as well), but do not constitute a fundamental objection to either adaptationist theorizing or its cousin, intentional system theory.
Neuroethology of releasing mechanisms: Prey-catching in toads
Authors: Ewert Jörg-Peter 
Published: February 2010

Abstract“Sign stimuli” elicit specific patterns of behavior when an organism's motivation is appropriate. In the toad, visually released prey-catching involves orienting toward the prey, approaching, fixating, and snapping. For these action patterns to be selected and released, the prey must be recognized and localized in space. Toads discriminate prey from nonprey by certain spatiotemporal stimulus features. The stimulus-response relations are mediated by innate releasing mechanisms (RMs) with recognition properties partly modifiable by experience. Striato-pretecto-tectal connectivity determines the RM's recognition and localization properties, whereas medialpallio-thalamo-tectal circuitry makes the system sensitive to changes in internal state and to prior history of exposure to stimuli. RMs encode the diverse stimulus conditions referring to the same prey object through different combinations of “specialized” tectal neurons, involving cells selectively tuned to prey features. The prey-selective neurons express the outcome of information processing in functional units consisting of interconnected cells. Excitatory and inhibitory interactions among feature-sensitive tectal and pretectal neurons specify the perceptual operations involved in distinguishing the prey from its background, selecting its features, and discriminating it from predators. Other connections indicate stimulus location. The results of these analyses are transmitted by specialized neurons projecting from the tectum to bulbar/spinal motor systems, providing a sensorimotor interface. Specific combinations of such projective neurons – mediating feature- and space-related messages – form “command releasing systems” that activate corresponding motor pattern generators for appropriate prey-catching action patterns.
The phylogeny and ontogeny of behavior
Authors: Skinner B. F. 
Published: February 2010

AbstractResponses are strengthened by consequences having to do with the survival of individuals and species. With respect to the provenance of behavior, we know more about ontogenic than phylogenic contingencies. The contingencies responsible for unlearned behavior acted long ago. This remoteness affects our scientific methods, both experimental and conceptual. Until we have identified he variables responsible for an event, we tend to invent causes. Explanatory entities such as “instincts,” “drives,” and “traits” still survive. Unable to show how organisms can behave effectively under complex circumstances, we endow them with special abilities permitting them to do so.Behavior exhibited by most members of a species is often accepted as inherited if all members were not likely to have been exposed to relevant ontogenic contingencies. When contingencies are not obvious, it is perhaps unwise to call any behavior either inherited or acquired, as the examples of churring in honey guides and following in imprinted ducklings show. Nor can the relative importance of phylogenic and ontogenic contingencies be argued from instances in which unlearned or learned behavior intrudes or dominates. Intrusions occur in both directions.Behavior influenced by its consequences seems directed toward the future, but only past effects are relevant. The mere fact that behavior is adaptive does not indicate whether phylogenic or ontogenic processes have been responsible for it. Examples include the several possible provenances of imitation, aggression, and communication. The generality of such concepts limits their usefulness. A more specific analysis is needed if we are to deal effectively with the two kinds of contingencies and their products.
How we know our minds: The illusion of first-person knowledge of intentionality
Authors: Gopnik Alison 
Published: February 2010

AbstractAs adults we believe that our knowledge of our own psychological states is substantially different from our knowledge of the psychological states of others: First-person knowledge comes directly from experience, but third-person knowledge involves inference. Developmental evidence suggests otherwise. Many 3-year-old children are consistently wrong in reporting some of their own immediately past psychological states and show similar difficulties reporting the psychological states of others. At about age 4 there is an important developmental shift to a representational model of the mind. This affects children's understanding of their own minds as well as the minds of others. Our sense that our perception of our own minds is direct may be analogous to many cases where expertise provides an illusion of direct perception. These empirical findings have important implications for debates about the foundations of cognitive science.
Nonconsequentialist decisions
Authors: Baron Jonathan 
Published: February 2010

AbstractAccording to a simple form of consequentialism, we should base decisions on our judgments about their consequences for achieving our goals. Our goals give us reason to endorse consequentialism as a standard of decision making. Alternative standards invariably lead to consequences that are less good in this sense. Yet some people knowingly follow decision rules that violate consequentialism. For example, they prefer harmful omissions to less harmful acts, they favor the status quo over alternatives they would otherwise judge to be belter, they provide third-party compensation on the basis of the cause of an injury rather than the benefit from the compensation, they ignore deterrent effects in decisions about punishment, and they resist coercive reforms they judge to be beneficial. I suggest that nonconsequentialist principles arise from overgeneralizing rules that are consistent with consequentialism in a limited set of cases. Commitment to such rules is detached from their original purposes. The existence of such nonconsequentialist decision biases has implications for philosophical and experimental methodology, the relation between psychology and public policy, and education.
Mathematical principles of reinforcement
Authors: Killeen Peter R. 
Published: February 2010

AbstractEffective conditioning requires a correlation between the experimenter's definition of a response and an organism's, but an animal's perception of its behavior differs from ours. These experiments explore various definitions of the response, using the slopes of learning curves to infer which comes closest to the organism's definition. The resulting exponentially weighted moving average provides a model of memory that is used to ground a quantitative theory of reinforcement. The theory assumes that: incentives excite behavior and focus the excitement on responses that are contemporaneous in memory. The correlation between the organism's memory and the behavior measured by the experimenter is given by coupling coefficients, which are derived for various schedules of reinforcement. The coupling coefficients for simple schedules may be concatenated to predict the effects of complex schedules. The coefficients are inserted into a generic model of arousal and temporal constraint to predict response rates under any scheduling arrangement. The theory posits a response-indexed decay of memory, not a time-indexed one. It requires that incentives displace memory for the responses that occur before them, and may truncate the representation of the response that brings them about. As a contiguity-weighted correlation model, it bridges opposing views of the reinforcement process. By placing the short-term memory of behavior in so central a role, it provides a behavioral account of a key cognitive process.
Gene therapy for neurodegenerative disorders and malignant brain tumors

Published: February 2010

AbstractGene therapy approaches have great promise in the treatment of neurodegenerative disorders and malignant brain tumors. Neuwelt et al. review available viral-mediated gene therapy methods and their blood-brain-barrier (BBB) disruption delivery technique, briefly mentioning nonviral mediated gene therapy methods. This commentary discussed the BBB disruption delivery technique, viral and nonviral mediated gene therapy approaches to Parkinson's disease, and the potential use of antisense oligo to suppress malignant brain tumors.
The ethics of fetal tissue grafting should be considered along with the science
Authors: Crutcher Keith A. 
Published: February 2010

AbstractIn addition to the scientific and medical issues surrounding the use of fetal tissue transplants, the ethical implications should be considered. Two major ethical issues are relevant. The first of these is whether this experimental procedure can be justified on the basis of potential benefit to the patient. The second is whether the use of tissue obtained from intentionally aborted fetuses can be justified in the context of historical and existing guidelines for the protection of human subjects. The separation of ethical decisions from medical practice and scientific research is necessary to prevent the exploitation of innocent human life.
The limitations of central nervous systemdirected gene transfer
Authors: Davidson Beverly L. 
Published: February 2010

AbstractComplementation and correction of a genetic defect with CNS manifestations lags behind gene therapy for inherited disorders affecting other organ systems because of shortcomings in delivery vehicles and access to the CNS. The effects of improvements in viral and nonviral vectors, coupled with the development of delivery strategies designed to transfer genetic material thoughout the CNS are being investigated by a number of laboratories in efforts to overcome these problems.
Building a rational foundation for neural transplantation
Authors: Davis Hasker P. , Volpe Bruce T. 
Published: February 2010

AbstractThe neural transplantation research described by Sinden and colleagues provides part of the rationale for the clinical application of neural transplantation. The authors are asked to clarify their view of the role of the cholinergic system in cognition, to address extrahippocampal damage caused by transient forebrain ischemia, and to consider the effects of delayed neural degeneration in their structure-function analysis.
Behavioral effects of neural grafts: Action still in search of a mechanism
Authors: Woodruff Michael L. 
Published: February 2010

AbstractThis commentary reviews data supporting circuitry reconstruction, replacement neurotransmitters, and trophic action as mechanisms whereby transplants promote recovery of function. Issue is taken with the thesis of Sinden et al. that adequate data exist to indicate that reconstruction of hippocampal circuitry damaged by hypoxia with CA1 transplants is a confirmed mechanism whereby these transplants produce recovery. Sinden et al.'s and Stein & Glasier's proposal that there is definitive evidence showing that all transplants produce trophic effects is also questioned.
Local and global gene therapy in the central nervous system
Authors: Muldoon Leslie L. , Neuwelt Edward A. 
Published: February 2010

AbstractFor focal neurodegenerative diseases or brain tumors, localized delivery of protein or genetic vectors may be sufficient to alleviate symptoms, halt disease progression, or even cure the disease. One may circumvent the limitation imposed by the blood-brain barrier by transplantation of genetically altered cell grafts or focal inoculation of virus or protein. However, permanent gene replacement therapy for diseases affecting the entire brain will require global delivery of genetic vectors. The neurotoxicity of currently available viral vectors and the transient nature of transgene expression invivomust be overcome before their use in human gene therapy becomes clinically applicable.
Finding the true place ofHomo habilisin language evolution
Authors: Bickerton Derek 
Published: February 2010

AbstractDespite some sound basic assumptions, Wilkins & Wakefield portray aHomo habilistoo linguistically sophisticated to fit in with the subsequent fossil record and thereby lose a reasoned explanation for human innovativeness. They err, too, in accepting a single-level model of conceptual structure and in deriving initial linguistic units from calls, a process far more dubious than the derivation of home-sign from naive gesture.
Single words, multiple words, and the functions of language
Authors: Catania A. Charles 
Published: February 2010

AbstractWilkins & Wakefield assign importance to motor systems but skip from anatomy to cognitive structure with little attention to behavior. Organisms, no matter how sophisticated, that do not behave in accord with what they know will fall by the evolutionary wayside. Facts about behavior can supplement the authors' theory, whose hierarchical structures can accommodate an evolutionary scenario in which a million years or more of functionally varied utterances mainly limited to single words is followed by an explosion of linguistic diversity with the development in the last 50,000 years or so of syntactically organized multiple word utterances.
Manual versus speech motor control and the evolution of language
Authors: Lieberman Philip 
Published: February 2010

AbstractInferences made from endocasts of fossil skulls cannot provide information on the function of particular neocortical areas or the subcortical pathways to prefrontal cortex that form part of the neural substrate for speech, syntax, and certain aspects of cognition. The neural bases of syntax cannot be disassociated from “communication.” Manual motor control was probably a preadaptive factor in the evolution of humansyntactic ability, but neurophysiological data on living humans show that speech motor control and syntax are more closely linked. The evolution of fully modern speech occurred fairly recently; thoughHomo habilismay have had some degree of speech and syntactic ability, it was not fully modern. Stone tools are uncertain indices of language or cognition.
Stone tools and conceptual structure
Authors: Steele James 
Published: February 2010

AbstractUnderstanding how conceptual structures inform stone tool production and use would help us resolve the issue of a pongid-hominid dichotomy in brain organisation and cognitive ability. Evidence from ideational apraxia suggests that the planning of linguistic and manipulative behaviours is not colocalized in homologous circuits. An alternative account in terms of the evolutionary expansion of the whole prefrontal-premotor area may be more plausible.
