Dehaene and Naccache, Dennett and Jack and Shallice “see convergence coming from many different quarters on a version of the neuronal global workspace model†(Dennett, p. 1). (Boldface references are to papers in this volume.) On the contrary, even within this volume, there are commitments to very different perspectives on consciousness. And these differing perspectives are based on tacit differences in philosophical starting places that should be made explicit.  Indeed, it is not clear that different uses of “consciousness†and (...) “awareness†in this volume can be taken to refer to the same phenomenon. More specifically, I think there are three different concepts of consciousness in play in this issue. The global workspace model makes much more sense on one of these than on the others.

This volume provides a fresh perspective on current democratic theory and practice by recovering the rich evaluations of democracy in the history of political thought. Each essay addresses a single thinker’s reflections on the virtues and defects of democracy and the relationship between democracy and other regimes.

The "great debate" in cognitive science today is about the nature of mental images. One side says images are basically pictures in the head. The other side says they are like the symbol structures in computers. If the picture-in-the-head theorists are right, then computers will never be able to think like people.This book contains the most intelligible and incisive articles in the debate, articles by cognitive psychologists, computer scientists and philosophers. The most exciting imagery phenomena are described, phenomena that indicate (...) that mental images can be rotated and scanned, that smaller images are harder to see than larger ones, that when mental images are made larger they eventually overflow, that the "screen" they overflow from has a determinable shape (elliptical), and that this "screen" subtends a determinate visual angle, the angle of vision of the mind's eye.Such experiments cry out for explanation. If images are pictures in the head, who (or what) looks at them? Why haven't brain scientists found them? Such questions are the subject of the great debate.IMAGERY is an excellent choice for courses in cognitive psychology, perception: artificial intelligence, computer science; philosophy of mind, of psychology and of science; minds and machines, science and society.Contributors include: Roger Brown and Richard Herrnstein (on the work of Roger N. Shepard), Daniel Dennett, Jerry Fodor, Robert Schwartz, Stephen Kosslyn, Steven Pinker, George Smith, Steven Shwartz, and Zenon Pylyshyn,. (shrink)

Austrian economics - the school of thought associated with Carl Menger, Frederick von Weiser, Eugen von Bohm-Bawerk, and in this century, Ludwig von Mises, Friedrich Hayek, Murray N. Rothbard, and Israel Kirzner - is based on a framework of methodological principles and assumptions much at variance with those of traditional or 'orthodox' economists. Robert Nozick, in his 'On Austrian Methodology', focuses attention on the most fundamental features of this framework, and subjects them to a thoroughgoing and scathing analysis. Singled out (...) for detailed and critical review are: (1) the praxeological concepts of methodological individualism; (2) the claim that economics is an a priori science of human action; (3) the nature of preference and its relation to choice and action; and (4) the assumptions of time-preference theory. Although Nozick does not consider Austrian views on business cycles, market process analysis, the coordinative and informational effects of the price system, competition, and several other fundamental aspects of praxeology, his criticism strikes at the very root of the praxeological school. This paper attempts to refute each criticism made of the praxeological school by Nozick on a point-by-point basis. It thus follows the same pattern as the original paper, and scrutinizes in detail the arguments made by its author. (shrink)

Libertarian punishment theory was initially articulated by Murray N. Rothbard and Walter E. Block. It was broken down into four separate stages. To a great degree, this theory was accepted by Eduardo Blasco and Davie Marcos. However, they maintain it is in need of some slight adjustments and improvements, mainly dealing with the interest rate. The present paper claims their suggestion while valid, is unnecessary, since this theory already incorporates that element, at least implicitly.

An attentional-associative model (Schmajuk et al. 1996), previously evaluated against multiple sets of classical conditioning data, is applied to causal learning. In agreement with Mitchell et al.'s suggestion, according to the model associative learning can be a conscious, controlled process. However, whereas our model correctly predicts blocking following or preceding subadditive training, the propositional approach cannot account for those results.

Today, unfortunately, we can not speak about the presence of one entire world philosophy. It is connected with the fact that the history of world philosophy is investigated from the position of eurocentrism, and what we consider as world philosophy actually is the West-European philosophy. In world philosophy, Eastern philosophy is represented only by three blocks: classical Chinese, Indian and Arabian philosophies. Even when we speak about Eastern philosophy, frequently it is examined as a marginal part of world philosophy which (...) has not played a significant role in its development. Thus concerning the question of development of world philosophy as a whole, the above given facts and other historical items of information prove: there is an entire world philosophy and it is a synthesis of East and West. So it is necessary to substantiate new methodological principles in studying world philosophy. (shrink)

Background Protecting a person’s right to privacy and confidentiality is important in healthcare services. As future health professionals, nursing students should bear the same responsibility as qualified health professionals in protecting patient privacy. Objectives To investigate nursing students’ practices of patient privacy protection and to identify factors associated with their practices. Research design A cross-sectional study design was adopted. A two-part survey was used to collect two types of data on nursing students: (1) personal characteristics, including demographics, clinical experience and (...) use of information and communication technology and social media and (2) practice of patient privacy protection, collected using the Patient Privacy Scale. Participants and research context: A total of 319 nursing students aged 18 or above, studying pre-registration nursing programmes and who had attended at least one block of clinical placement, were recruited from a university in Hong Kong. Ethical considerations The study received ethical approval from the Survey and Behavioural Research Ethics Committee of the Chinese University of Hong Kong. The participants were informed of the study aim and written consent was obtained before completing the survey. Findings: The mean total score on the Patient Privacy Scale was 119.7 out of 135. Nursing students who were regular users of Instagram and those who had never taken photographs with patients and hence did not need to obtain patient consent were associated with better practices of patient privacy protection (higher total scores on the Patient Privacy Scale). Conclusions The findings improve our understanding of nursing students’ practice of patient privacy protection and the associated factors. This will inform the development and revision of current strategies to enhance nursing students’ practice of patient privacy protection, especially their use of social media. (shrink)

Upshot: We consider that elementary students’ situated activities with geometric transformations and animation contain the seeds of complex, and eventually, mathematically generalizable and abstract reasoning. Further studies can explore such technologically-based activities’ potential as building blocks for flexible, creative, and formalized knowledge.

A materialist construction of semiosis requires system embodiment at particular locales, in order to function as systems of interpretance. I propose that we can use a systemic model of scientific measurement to construct a systems view of semiosis. I further suggest that the categories required to understand that process can be used as templates when generalizing to biosemiosis and beyond. The viewpoint I advance here is that of natural philosophy—which, once granted, incurs no principled block to further generalization all the (...) way to pansemiotics—nearer to Peirce’s own very general perspective. This project requires a hylozooic framework, which I present in the form of a specification hierarchy, whereby physical dynamics subsume all other transactions at more highly developed integrative levels. The upshot of the paper is a proposal that meanings can be assimilated most generally to final causes. (shrink)

Fused, elongated mitochondria are more efficient in generating ATP than fragmented mitochondria. In diverse C. elegans longevity pathways, increased levels of fused mitochondria are associated with lifespan extension. Blocking mitochondrial fusion in these animals abolishes their extended longevity. The long‐lived C. elegans vhl‐1 mutant is an exception that does not have increased fused mitochondria, and is not dependent on fusion for longevity. Loss of mammalian VHL upregulates alternate energy generating pathways. This suggests that mitochondrial fusion facilitates longevity in C. elegans (...) by increasing energy metabolism. In diverse animals, ATP levels broadly decreases with age. Substantial evidence supports the theory that increasing or maintaining energy metabolism promotes the survival of older animals. Increased ATP levels in older animals allow energy‐intensive repair and homeostatic mechanisms such as proteostasis that act to prevent cellular aging. These observations support the emerging paradigm that maintaining energy metabolism promotes the survival of older animals. (shrink)

Background:: Over the past few years, research ethics committees have increasingly demanded explicit consent before archival tissue samples can be used in research projects. Current UK guidance in this area requires an assessment of whether it is “practical” to obtain explicit consent. Ethics committees have little experience or evidence to help them to judge what is “practical” in this context.Methods:: We attempted to obtain general consent for research use of surplus tissue from renal transplant biopsies from the entire patient population (...) of the renal transplant unit in Leicester. The nature of this patient population would be expected to facilitate this task.Results:: A total of 495 letters were sent. Attempts were made to contact non-responders when they attended the outpatient clinic. One year after the initiation of the project, the opinions of 26% of the patients had still not been ascertained.Conclusions:: The results confirm that the vast majority of patients are happy for “surplus” biopsy material to be used for research; the situation does not parallel the use of autopsy tissue. A requirement to obtain explicit consent for the study of archival tissue is likely, however, to block or at least seriously delay research, which is contrary to the public interest and specifically may harm the interests of the patients concerned. In the UK, the problem of tissue being used against the wishes of the donor has now been largely replaced by the problem of prohibition of tissue use against the wishes of the donor. (shrink)

I have attempted to clarify some of the pathways in the development of Darwin's thinking. The foregoing examples of influence by no means include all that can be found by comparing Darwin's writings with Humboldt's. However, the above examples seem adequate to show the nature and extent of this influence. It now seems clear that Humboldt not only, as had been previously known, inspired Darwin to make a voyage of exploration, but also provided him with his basic orientation concerning how (...) and what to observe and how to write about it. An important part of what Darwin assimilated from Humboldt was an appreciation of population analysis as a tool for assessing the state of societies and of the benefits and hardships which these societies can expect to receive from the living world around them.Darwin exhibited in his Journal of Researches a casual interest in the economic and political conditions of the countries he visited, but these considerations were much less important to him than to Humboldt. Instead, Darwin, with the assistance of Lyell's Principles of Geology, shifted from Humboldt's largely economic framework to a biological one built around the species question. This shift led Darwin away from a consideration of how the population biology of animals was related to man's economy to focus instead upon how population biology fitted into the economy of nature.Humboldt's Personal Narrative served very well as a model for Darwin's Journal of Researches, thereby helping Darwin gain scientific eminence. The Journal of Researches, like virtually all of Humboldt's writings, was a contribution to scientific orthodoxy. But Darwin had, along the way, acquired an urge to do more than just add his building blocks to the orthodox scientific edifice. He decided to rearrange those blocks of knowledge into a different structure, and for that task neither Humboldt's Personal Narrative nor any other of his works could serve as a model. Humboldt had lacked the confidence which Darwin needed that biogeography and the origin of species could be understood. Humboldt had not explored very far the possible connections between biology and geology. Nor had he provided a general synthetic account of population biology. Had he done so, he might have been more explicit about the extent of his endorsement of Malthus. But even if he had, Humboldt's strong orientation toward cooperation would probably have inhibited his recognition of the importance of competition in nature.Lyell, who had also benefited from reading Humboldt, gave Darwin insights that were lacking in Humboldt's Personal Narrative. Lyell admirably demonstrated how stratigraphy, paleontology, biogeography, and population biology could be interrelated, and his reasons for doing so were essentially the same as Darwin's. Lyell's understanding of biogeography and ecology came from the writings of Augustin-Pyramus de Candolle as much as from Humboldt's, and from the former Lyell derived an appreciation for the importance of competition and also a confidence that the mysteries of biogeography could be explained.117 Furthermore, Lyell's discussion of all these subjects and also of evolution in his Principles of Geology is a good synthetic argument that was the ideal model for Darwin's greatest book.Darwin, having become convinced that species change through time, was able to synthesize in his mind the contributions which he had derived from the writings of Humboldt and Lyell as they applied to the species question. When Darwin wrote his Journal of Researches there were two large gaps in his thinking about evolution that bothered him—the mechanism of evolution and the causes of extinction. It was only after reading Malthus in 1838 that he realized, as Lyell had more or less pointed out, how important was competition in nature. He now had the general outlines for his theory, and in the 1845 abridged edition of his Journal, now retitled The Voyage of the Beagle, he inserted a fuller discussion of competition in nature which showed his awareness of its importance as an ecological factor.118.

Despite their seemingly endless diversity, proteins adopt a limited number of structural forms. It has been estimated that 80% of proteins will be found to adopt one of only about 400 folds, most of which are already known. These folds are largely formed by a limited ‘vocabulary’ of recurring supersecondary structure elements, often by repetition of the same element and, increasingly, elements similar in both structure and sequence are discovered. This suggests that modern proteins evolved by fusion and recombination from (...) a more ancient peptide world and that many of the core folds observed today may contain homologous building blocks. The peptides forming these building blocks would not in themselves have had the ability to fold, but would have emerged as cofactors supporting RNA‐based replication and catalysis (the ‘RNA world’). Their association into larger structures and eventual fusion into polypeptide chains would have allowed them to become independent of their RNA scaffold, leading to the evolution of a novel type of macromolecule: the folded protein.

The formulation and implementation of policies addressing the need to adapt to climate change can be difficult due to the long-term, uncertain nature of localised climate change impacts and associated vulnerabilities. Difficulties are intensified because policy interventions can involve high costs, foregone opportunity and changes to people's way of life. Factors such as these can spur an uncritical, or reflexive, negativity regarding efforts to address the projected impacts of climate change. Such reflexive negativity is often trivialised in pejorative terms, such (...) as 'Nimbyism'. However, stakeholder reluctance to accept the need for adaptation planning may be strongly influenced by self-perceptions that are resistant to change. People's sense of self and sense of place may contribute to an 'imaginative intangibility' with respect to climate adaptation, blocking thoughtful reflection and deliberation regarding alternative approaches and providing rationales for cheating the system once implemented. If acknowledged and addressed in a sensitive manner, it may be possible to manage these self-perceptions to elevate public discourse about climate change and help create situationally appropriate adaptation policy regimes.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 33.2 (2000) 101-115 [Access article in PDF] Case Study of the Use of a Circumstantial Ad Hominem in Political Argumentation Douglas Walton In the 1860s, Northern newspapers attacked Lincoln's policies by attacking his character, using the terms drunk, baboon, too slow, foolish, and dishonest. Steadily on the increase in political argumentation since then, the argumentum ad hominem has been carefully refined as an instrument of "oppo (...) tactics" and "going negative" by the public relations experts who now craft political campaigns at the national level. It has been so prominently used in the major political campaigns, debates, and advertisements of the past few years that there has even been a reaction against it--a feeling that we have gone too far in this direction and that some kind of restraint is needed. 1 But there has been no evidence of such restraint in the argumentation used in recent campaigns. Perhaps what might be helpful is a better understanding on the part of voters and campaigners of how to evaluate ad hominem arguments critically.How does the ad hominem argument really work as a way of molding public opinion, why is it so often so effective, and how can it be defended against? How can it be evaluated as a clearly identifiable type of argument, by some kind of objective standards, in a way that can be applied to particular cases? These appear to be tough questions, but recent research has made some not inconsiderable progress toward answering them.The purpose of this article is to present a new case study of a type of argument commonly used in political discourse, a case study that makes use of the dialectical normative framework for identifying and evaluating personal attack (ad hominem) arguments that is developed in a series of works by Henry W. Johnstone Jr. (1952); Alan Brinton (1985, 1995); Frans H. van Eemeren and Rob Grootendorst (1984, 1995); Erik C. W. Krabbe and Douglas N. Walton (1993), Walton (1989, chap. 6; 1998); and van Eemeren, Grootendorst, Francisca Snoeck Henkemans et al. (1996). This particular case, although typical of so many ad hominem arguments currently [End Page 101] in use in political discourse, has some special features that turn out to be quite interesting not only in showing how the dialectical framework applies to cases, but also in advancing our knowledge of how the ad hominem type of argument works in political argumentation in a democratic system for which the media reportage of events is a big factor in influencing voting. 1. Framework for analysis and evaluation Although the argumentum ad hominem, or personal attack argument, has been traditionally treated as a fallacy in logic, recent research in argumentation (as cited above) shows that, in many cases,--including cases in political argumentation--ad hominem arguments, as used in conversational arguments, are not fallacious. Research has shown that, while some personal attack arguments can definitely be judged fallacious, many others are quite reasonable (when evaluated in the appropriate context), while still others should be evaluated as weak (insufficiently supported) but not fallacious. As shown in this case study, the real function of an ad hominem argument (when properly used) is to attack an arguer's credibility in order to criticize the argument she advocates.Before going any further, it is necessary to define some terminology brought to use in the research cited above. An ad hominem argument is the use of personal attack in a dialogue exchange between two parties, where the one party attacks the character of the other party as bad, in some respect, and then uses this attack as a basis for criticizing the other party's argument. An argument is fallacious if it is a special baptizable (Johnson 1987) type of argument that is used by one party in a dialogue exchange in such a way that it blocks or interferes with the collaborative realization of the goal of the type of dialogue in which the two participants are supposed to be engaged (Walton 1995).

This paper is based on four assumptions concerning the analysis of the construction of collective identities. First, such construction, like power and economic relations, is an analytically autonomous basic component of the construction of social life. Second, such constructions have been going on in all human societies throughout history. Third, all such patterns of collective identity have been continually constructed from some basic yet continually changing building blocks, codes or themes - especially those of primordiality, civility and `sacredness'. The paper (...) focuses on the different patterns of modern nation states in the framework of the more general approach to the construction of collective identities. This analysis of different modern nation states indicates that despite common characteristics, there developed great differences in their construction; in the analysis of such differences it is very important to take into account the historical and civilizational backgrounds of the respective societies.

In daily life we not only speak not only of knowing facts but also of know-how. We may not only judge that someone knows that the stock market is in decline, that an avalanche is imminent or that ice is not marble but also that someone knows how to make money on the stock exchange, knows how to survive an avalanche or knows how to carve a realistic life-sized human figure from a block of marble. Ryle first drew attention to (...) analysis of know-how and argued that know-how does not consist of propositional knowledge. He went on to give an analysis of know-how. Since then the analysis of propositional knowledge has largely overshadowed that of know-how. However there has been a resurgence of interest in it. For example, relatively recent proposals in philosophy of mind and ethics proceed in terms of know-how. For example, in response to Frank Jackson’s knowledge argument, David Lewis replies that knowing what an experience is like is a matter of knowing how to recognise, remember and imagine it. Hilary Putnam claims that “knowing the meaning of the word ‘gold’ or of the word ‘elm’ is not a matter of knowing that at all, but a matter of knowing how”. A more specific variant on this claim is Michael Devitt’s conclusion that someone who knows the meaning of a term knows how to use it with a certain meaning but that such a person need not have ‘any propositional knowledge about what constitutes its meaning’.

We describe here recent work on the molecular genetics of mitosis in the filamentous fungus Aspergillus nidulans. Aspergillus is one of three simple eukaryotes with powerful genetic systems that have been used to analyze mitosis. The modern molecular biological techniques available with this organism have made it possible to use mutations to identify genes and proteins that play an important role in mitosis. Three Aspergillus genes that affect mitosis are described. One gene, nimA, is specifically expressed late in the cell (...) cycle and codes for a putative protein kinase that induces mitosis, even in cells blocked in S‐phase. The second gene, bimG, codes for a putative phosphatase that interacts functionally with the nimA kinase. The third gene, bimE, codes for a protein that suppresses mitosis during interphase, apparently by keeping nimA turned off. None of these genes appear to be similar to any of the genes affecting mitosis that have been characterized in other eukaryotes, but rather appear to be elements of a system that prevents mitosis from occurring during interphase.

Current arguments to increase shareholder power in the large public U.S. corporation need to take account of the well-established historical practice of extensive delegation by shareholders of business decision-making and agenda-control to management and the board, what might be characterized as an absolute delegation rule. This practice sharply limits the power of shareholders to put either business or governance proposals to the shareholders for dispositive resolution. The paper, originally published in 1991 but newly relevant, argues that the rule is based (...) on potential pathologies in shareholder voting rather than the inherent information asymmetry between shareholders and managers. Rational shareholders who know of this asymmetry (and know that others know) would simply vote against most shareholder proposals. But shareholder voting gives rise to potential cycling problems, as shifting shareholder majorities vie for preferred policies, and potential opportunism, as shareholders engage in side deals with management and other shareholders to extract rents in corporate decision-making. Since shareholding patterns are in part a response to control rights, deviations from the absolute delegation rule will predictably lead to greater block ownership, for defensive and offensive reasons. These concerns need to be addressed in arguments for the expansion of shareholder power. (shrink)

The articles reviews the problem of humanitarian terrorism that is a terrorism of self-proclaimed humanitarian goals and self-inflicted constraints. This type of terrorism justifies itself by lofty aspirations and claims that its actions are targeted killings of guilty individuals only. This terrorism is the product of the Enlightenment, it emerged by the end of the 18th century and passed three stages in its development. The first stage is the classical terror of the Jacobins 1793–1794. The second one is Russian revolutionary (...) terror of the end of the 19th – early 20th centuries. The third stage is the contemporary American warfare waged by the unmanned aerial vehicles, called drones. From the perspective of the contemporary just war theory, this terrorism is not only morally superior to the ordinary primitive terrorism of straightforward attacks on civilians (this terrorism may be no less fair in terms of self-imposed goals, but is doubtful in terms of means), but even contemporary war. Terrorists of this type kill the few but teach a lesson to many. But it must be clearly born in mind that humanitarian terrorism is not only the summit of just war but also the summit of absolute war. It is founded in personal and individual enmity, which makes the core of absolute enmity. Absolute enmity may at times be inevitable and even justified, but it blocks the road to peace. Revengeful spite, stemming from absolute enmity, is capable of creating its own phantoms of justice, propelling the war. The author concludes that the vicious circle is thus completed. The logic of just war drags in the direction humanitarian terrorism, humanitarian terrorism drags in the mire of absolute enmity. Absolute enmity proclaims just war. (shrink)

ABSTRACTMemory bias is a risk factor for depression. In two independent studies, the efficacy of one CBM-Memory session on negative memory bias and depressive symptoms was tested in vulnerable samples. We compared positive to neutral CBM-Memory trainings in highly-ruminating individuals and individuals with elevated depressive symptoms. In both studies, participants studied positive, neutral, and negative Swahili words paired with their translations. In five study–test blocks, they were then prompted to retrieve either only the positive or neutral translations. Immediately following the (...) training and one week later, we tested cued recall of all translations and autobiographical memory bias; and also measured mood, depressive symptoms, and rumination. Retrieval practice resulted in training-congruent recall both immediately after and one week after the training. Overall, there was no differential decrease in symptoms or difference in autobiographical memory bias between the tra... (shrink)

Punishment is fundamentally unfair, never justly deserved, and cannot be eliminated. The deep Belief in a Just World, the subject of extensive psychological research, makes it difficult for us to accept the fact that we live in an unjust world. Belief in moral responsibility is designed to protect our comfortable belief in a just world, but that comfort comes at the price of blaming victims and blocking deeper inquiry. Facing the disturbing fact of unavoidable injustice motivates us to take effective (...) steps to minimize injustice: to seek out the deeper causes of criminal behavior and fix them, and to treat those we must unjustly punish (through coercive isolation) with respect, concern, and the least possible discomfort.

Defect detection is a major concern in quality control of various products in industries. This paper presents two different machine-vision based methods for detecting defects on periodically patterned textures. In the first method, input defective image is split into several blocks of size same as the size of the periodic unit of the image and chi-square histogram distances of each periodic block with respect to itself and all other periodic blocks are calculated to get a dissimilarity matrix. This dissimilarity matrix (...) is subjected to Ward's hierarchical clustering to automatically identify defective and defect-free blocks. The second method of defect detection is based on Universal Quality Index which is a measure of loss of correlation, luminance distortion and contrast distortion between any two signals. Quality indices of a periodic block with respect to itself and all other periodic blocks are calculated to get a similarity matrix containing quality indices. Specific variances of the periodic blocks are derived from the quality index matrix through orthogonal factor model based on eigen decomposition. These variances are subjected to Ward's hierarchical clustering to automatically identify defective and defect-free blocks. Results of experiments on real fabric images with defects show that the defect detection methods based on chi-square histogram distance and universal quality index yield a success rate of 98.6% and 97.8% respectively.

This synthetic genome, named M. genitalium JCVI-1.0, contains all the genes of wild-type M. genitalium G37 except MG408, which was disrupted by an antibiotic marker to block pathogenicity and to allow for selection. To identify the genome as synthetic, we inserted "watermarks" at intergenic sites known to tolerate transposon insertions. Overlapping "cassettes" of 5 to 7 kilobases (kb), assembled from chemically synthesized oligonucleotides, were joined by in vitro recombination to produce intermediate (...) assemblies of approximately 24 kb, 72 kb ("1/8 genome"), and 144 kb ("1/4 genome"), which were all cloned as bacterial artificial chromosomes in Escherichia coli. Most of these intermediate clones were sequenced, and clones of all four 1/4 genomes with the correct sequence were identified. The complete synthetic genome was assembled by transformation-associated recombination cloning in the yeast Saccharomyces cerevisiae, then isolated and sequenced. A clone with the correct sequence was identified. The methods described here will be generally useful for constructing large DNA molecules from chemically synthesized pieces and also from combinations of natural and synthetic DNA segments. 10.1126/science.1151721.

Visuomotor adaptation to novel environments can occur via non-physical means, such as observation. Observation does not appear to activate the same implicit learning processes as physical practice, rather it appears to be more strategic in nature. However, there is evidence that interspersing observational practice with physical practice can benefit performance and memory consolidation either through the combined benefits of separate processes or through a change in processes activated during observation trials. To test these ideas, we asked people to practice aiming (...) to targets with visually rotated cursor feedback or engage in a combined practice schedule comprising physical practice and observation of projected videos showing successful aiming. Ninety-three participants were randomly assigned to one of five groups: massed physical practice, distributed physical practice, or one of 3 types of combined practice: alternating blocks, or all observation before or after blocked physical practice. Participants received 100 practice trials. All groups improved in adaptation trials and showed savings across the 24-h retention interval relative to initial practice. There was some forgetting for all groups, but the magnitudes were larger for physical practice groups. The Act and Obs_During groups were most accurate in retention and did not differ, suggesting that observation can serve as a replacement for physical practice if supplied intermittently and offers advantages above just resting. However, after-effects associated with combined practice were smaller than those for physical practice control groups, suggesting that beneficial learning effects as a result of observation were not due to activation of implicit learning processes. Reaction time, variable error, and post-test rotation drawings supported this conclusion that adaptation for observation groups was promoted by explicit/strategic processes. (shrink)

To localize wheat ESTs on chromosomes, 882 homoeologous group 6-specific ESTs were identified by physically mapping 7965 singletons from 37 cDNA libraries on 146 chromosome, arm, and sub-arm aneuploid and deletion stocks. The 882 ESTs were physically mapped to 25 regions flanked by 23 deletion breakpoints. Of the 5154 restriction fragments detected by 882 ESTs, 2043 were localized to group 6 chromosomes and 806 were mapped on other chromosome groups. The number of loci mapped was greatest on chromosome 6B and (...) least on 6D. The 264 ESTs that detected orthologous loci on all three homoeologs using one restriction enzyme were used to construct a consensus physical map. The physical distribution of ESTs was uneven on chromosomes with a tendency toward higher densities in the distal halves of chromosome arms. About 43% of the wheat group 6 ESTs identified rice homologs upon comparisons of genome sequences. Fifty-eight percent of these ESTs were present on rice chromosome 2 and the remaining were on other rice chromosomes. Even within the group 6 bins, rice chromosomal blocks identified by 1-6 wheat ESTs were homologous to up to 11 rice chromosomes. These rice-block contigs were used to resolve the order of wheat ESTs within each bin. (shrink)

Aims. Currently, methylphenidate (MPH, trade name Ritalin) is the most widely prescribed medication for attention deficit/hyperactivity disorder (ADHD). We examined the ability of repeated MPH administration to produce a sensitized appetitive eagerness type response in laboratory rats, as indexed by 50-kHz ultrasonic vocalizations (50-kHz USVs). We also examined the ability of MPH to reduce play behavior in rats which may be partially implicated in the clinical efficacy of MPH in ADHD. Design. 56 adolescent rats received injections of either 5.0 mg/kg (...) MPH, or vehicle each day for 8 consecutive days, and a week later received a challenge injection of either MPH or vehicle. Measurements. Both play behavior (pins) and 50-kHz USVs were recorded after each drug or vehicle administration. Results. MPH challenge produced a substantial 73% reduction in play behavior during the initial treatment phase, and during the last test (1 week post drug), 50-kHz USVs were elevated approximately threefold only in animals with previous MPH experience. Conclusions. These data suggest that MPH treatment may lead to psychostimulant sensitization in young animals, perhaps by increasing future drug-seeking tendencies due to an elevated eagerness for positive incentives. Further, we hypothesize that MPH may be reducing ADHD symptoms, in part, by blocking playful tendencies, whose neuro-maturational and psychological functions remain to be adequately characterized.

Data hiding and watermarking are considered one of the most important topics in cyber security. This article proposes an optimized method for embedding a watermark image in a cover medium (color image). First, the color of the image is separated into three components (RGB). Consequently, the discrete wavelet transform is applied to each component to obtain four bands (high–high, high–low, low–high, and low–low), resulting in 12 bands in total. By omitting the low–low band from each component, a new square matrix (...) is formed from the rest bands to be used for the hiding process after adding keys to it. These keys are generated using a hybrid approach, combining two chaotic functions, namely Gaussian and exponential maps. The embedding matrix is divided into square blocks with a specific length, each of which is converted using Hessenberg transform into two matrices, P and H. For each block, a certain location within the H-matrix is used for embedding a secret value; the updated blocks are assembled, and the reverse process is performed. An optimization method is applied, through the application of the firework algorithm, on the set of the initial values that generate keys. Using an optimization procedure to obtain keys requires performing lowest possible change rate in an image and maintain the quality of the image. To analyze and test the efficiency of the proposed method, mean-square error (MSE) and peak signal-to-noise ratio (PSNR) measurements are calculated. Furthermore, the robustness of the watermark is computed by applying several attacks. The experimental results show that the value of the MSE is reduced by about 0.01 while the value of the PSNR is increased by about 1.25 on average. Moreover, the proposed method achieved a high-retrieval rate in comparison with the non-optimization approach. (shrink)

From certain sorts of premise, individuals reliably infer invalid conclusions. Two Experiments investigated a possible cause for these illusory inference: Reasoners fail to think about what is false. In Experiment 1, 24 undergraduates drew illusory and control inferences from premises based on exclusive disjunctions (“or else”). In one block, participants were instructed to falsify the premises of each illusory and control inference before making the inference. In the other block, participants did not receive these instructions. There were more correct answers (...) for illusory disjunctions whose premises had been falsified than there were for illusory disjunctions that had not been falsified. A second Experiment introduced illusory inferences in a real world context that accentuated falsification of premises. Accuracy also improved. Knowledge of how to falsify premises and to consider their implications for true premises transferred to a new problem introduced at the end of the Experiment without the falsification instruction. The participants' ratings of the difficulty of the inferences showed that they did not err simply because illusory inferences are perceived to be more difficult than control problems. The model theory predicts these results because it postulates that the limitations of working memory preclude the representation of false information. (shrink)
