Effective altruism is a movement which aims to maximise good. Effective altruists are concerned with extreme poverty and many of them think that individuals have an obligation to donate to effective charities to alleviate extreme poverty. Their reasoning, which I will scrutinise, is as follows: -/- Premise 1. Extreme poverty is very bad. -/- Premise 2. If it is in our power to prevent something very bad from happening, without thereby sacrificing anything else morally significant, we ought, morally, to do (...) it. -/- Premise 3. Individuals ought to choose the effective option in preventing very bad things. -/- Premise 4. Donating to effective charities is one of the best ways to alleviate extreme poverty. -/- Conclusion. Individuals ought to donate to effective charities working towards extreme poverty alleviation where doing so does not require them to give up anything of moral significance. -/- I will scrutinise each of these premises in turn. -/- For Premise 1, I focus on hedonistic utilitarianism and criticise its outlook on extreme poverty. I claim that hedonistic utilitarianism might be problematic for effective altruism. -/- Premise 2 is Peter Singer's Weaker Principle of Sacrifice. I introduce several possible interpretations of it, and press several objections to it by stressing overpermissiveness, luck, and rights. I defend strengthening the Weaker Principle of Sacrifice without making it overdemanding. -/- I claim that Premise 3 can be attractive to both consequentialists and non-consequentialists. Nevertheless, by showing that effectiveness sometimes violates fairness, I propose a method which avoids always helping the greater number and always giving everyone equal chances of being helped, which is compatible with effective altruism. -/- Against Premise 4, I assess the systemic change objection, which states that effective altruism unjustifiably distracts individuals from systemic change. By considering risk and the moral standing of the future extremely poor, I claim that the systemic change objection is partially successful, but cannot undermine effective altruism. -/- After analysing all of these, I argue that individuals have an obligation to donate to effective charities to alleviate extreme poverty where doing so does not require them to give up anything of moral significance.

Since at least the mid-1980s claims have been made for rationality in rats. For example, that rats are capable of inferential reasoning (Blaisdell, Sawa, Leising, & Waldmann, 2006; Bunsey & Eichenbaum, 1996), or that they can make adaptive decisions about future behavior (Foote & Crystal, 2007), or that they are capable of knowledge in propositional-like form (Dickinson, 1985). The stakes are rather high, because these capacities imply concept possession and on some views (e.g., Rödl, 2007; Savanah, 2012) rationality (...) indicates self-consciousness. I evaluate the case for rat rationality by analyzing 5 key research paradigms: spatial navigation, metacognition, transitive inference, causal reasoning, and goal orientation. I conclude that the observed behaviors need not imply rationality by the subjects. Rather, the behavior can be accounted for by noncognitive processes such as hard-wired species typical predispositions or associative learning or (nonconceptual) affordance detection. These mechanisms do not necessarily require or implicate the capacity for rationality. As such there is as yet insufficient evidence that rats can reason. I end by proposing the ‘Staircase Test,’ an experiment designed to provide convincing evidence of rationality in rats. (shrink)

The Zhuangzi begins with Peng, a soaring bird transformed from a bounded fish, which is the first metaphor that points beyond limited standpoints to a higher point of view. The transformation is one-way and symbolizes that there is a higher viewpoint to attain which affords mental freedom and the clarity and scope of great vision. Under the alternate thesis of constant transformation, values and understandings must ceaselessly transform and collapse. All cyclical transformations must collapse into skeptical relativism and confusion. But (...) Peng does not turn back into a fish, and the awakened sage does not fall into a slumber of ignorance and confusion. It is only the thesis of a one-way transformation that leaves the sage in a state of knowledge. (shrink)

Ascorbic acid (vitamin C) is a water-soluble vitamin; it is present in the highest concentration in the brain. Ascorbic acid in high doses acts as a potential treatment for various neuropathological and psychiatric conditions. Flumazenil is a benzodiazepine antagonist; it competitively inhibits the activity of benzodiazepine and non-benzodiazepine substances that interact with benzodiazepine receptors site on the GABA/benzodiazepine receptor complex. This study aims to investigate the effect of flumazenil on the anxiolytic action of ascorbic acid using an elevated plus maze (...) model of anxiety in rats. Male Albino Wistar rats weighing between 250 and 320 grams were used. Rats were divided into four equal groups of seven rats each and treated as follows: Group I, the control group received a single dose of 1.0% tween 80; Group II treated with a single dose of 125 mg/kg ascorbic acid; Group III was injected by a single dose of 1.0 mg/kg flumazenil; Group IV received a combination treatment of 125 mg/kg ascorbic acid and 1.0 mg/kg flumazenil. Behavioural measurements using a plus maze were scored 30 min after the administration. The parameters scored are the time spent on the open and closed arms, the lines and number of entries into open and closed arms, and the anxiety measure. Ascorbic acid decreased anxiety measure and increased the total lines and total number of entries; this effect was abolished by the administration of flumazenil with ascorbic acid. Thus, ascorbic acid produces an anxiolytic-like effect in rats; this effect was abolished by flumazenil administration with ascorbic acid. This may indicate that the GABA/benzodiazepine receptor complex has to be stimulated to produce the anxiolytic effect. (shrink)

There have been several recent attempts to think about psychological kinds as homologies. Nevertheless, there are serious epistemic challenges for individuating homologous psychological kinds, or cognitive homologies. Some of these challenges are revealed when we look at competing claims of cognitive homology. This paper considers two competing homology claims that compare human anger with putative aggression systems of nonhuman animals. The competition between these hypotheses has been difficult to resolve in part because of what I call the boundary problem: boundaries (...) between instances of psychological kinds (e.g., anger and fear) cannot be directly observed. Thus, there are distinctive difficulties for individuating psychological kinds across lineages. I draw four conclusions from this case study: First, recent evidence from the neuroscience of fear suggests that one of the proposed homologies involves a straightforward conflation of anger and fear. Second, this conflation arises because of the boundary problem. Third, there is an implicit constraint on the operational criteria that is easy to overlook in the psychological case. In this case, ignoring the constraint is part of the problem. Fourth, this is a clear case in which knowledge of homology cannot be accumulated piecemeal. Identifying homologs of human anger requires identifying homologs of fear. (shrink)

Parkinson’s disease is a common movement disorder associated primarily with oxidative stress-mediated degeneration of dopaminergic neurons. Earlier studies showed that Sorghum bicolor-based supplement (SbS) exhibited antioxidant and neuroprotective activities and might likely rescue the death of dopaminergic neurons in Parkinson’s disease. This study examined the effect of SbS on rotenone-induced Parkinsonian-like motor deficits in rats and the involvement of oxidative stress and pro-inflammatory cytokines. Rats were divided into six groups and treated orally with sunflower oil (vehicle-control), rotenone (2.5 (...) mg/kg) alone or in combination with each dose of SbS (50, 100, and 200 mg/kg) and levodopa-carbidopa (10 mg/kg) on an alternate day for 28 days. The changes in motor functions were evaluated on day 28 and the brain concentrations of oxidative stress biomarkers and pro-inflammatory cytokines (tumor necrosis factor-alpha and interleukin-6) were determined. Rotenone caused motor deficits by impaired locomotor activity in the open field test and induced catalepsy in the bar test, which were attenuated by SbS. Rats pretreated with SbS had reduced brain levels of malondialdehyde, nitrite, and pro-inflammatory cytokines compared to rotenone controls. SbS mitigated rotenone-induced depletion of reduced glutathione and antioxidant enzymes in the rat brain. The results suggest that SbS ameliorated rotenone-induced Parkinsonian-like motor dysfunctions by reducing neuronal oxidative stress and pro-inflammatory cytokines in rats. (shrink)

Abstract: This study was aiming to determine the effect of the Vitamin A on paracetamol-induced hepatotoxicity. Fifteen rats were randomly divided into five groups; (three rats each) control group, paracetamol (1000 mg/kg body weight) was used to induce hepatotoxicity in albino rats. Vitamin A (Retinyl palmtate) administered at the dose levels of 100, 500 and1000 IU/kg body weights orally for 7 days prior to paracetamol dose. Hepatic toxicity was observed in paracetamol group; aspartate aminotransaminase (AST) level was (...) high as compared with control group (p = 0.003). The significant hepatoprotective effect of Vitamin A was observed at doses 500 and 1000 IU/kg body weight, as there was significant reduction of serum AST when compared to paracetamol group (p = 0.01 and 0.003 respectivly), where 100 IU/Kg vitamin A not significantly decrease AST. Liver trace element determined by X-ray fluorescence (XRF) (K, Ca, Fe, Cu, Zn and Rb) in paracetamol-treated group were found to be higher than that of the control group, although the only significant increase was observed with Cu. Br shows slight decrease compared to the control group. There were no significant differences between Vitamin A groups (100 mg/kg 500mg/kg and 1000mg/kg) and PCM-treated group in the liver tissue content of Ca, K, Zn, Cu, Rb and Br where Fe concentrations were significantly decrease at doses 500 and 1000IU/l (P value 0.05 and 0.045 respectively). Vitamin A shows protective effect by regulating liver tissue Fe. We recommend to perform further investigation on the mechanisms of Vitamin A hepatoprotective mechanisms of action. (shrink)

The mainstream tradition in recent Anglophone Zhuangzi interpretation treats spontaneous skillful responsiveness – similar to the spontaneous responsiveness of a skilled artisan, athlete, or musician – as a, or the, Zhuangzian ideal. However, this interpretation is poorly grounded in the Inner Chapters. On the contrary, in the Inner Chapters, this sort of skillfulness is at least as commonly criticized as celebrated. Even the famous passage about the ox-carving cook might be interpreted more as a celebration of the knife’s passivity than (...) as a celebration of the cook’s skillfulness. (shrink)

Clinical evidence has shown that physical exercise during pregnancy may alter brain devel- opment and improve cognitive function of offspring. However, the mechanisms through which maternal exercise might promote such effects are not well understood. The present study examined levels of brain-derived neurotrophic factor (BDNF) and absolute cell num- bers in the hippocampal formation and cerebral cortex of rat pups born from mothers exer- cised during pregnancy. Additionally, we evaluated the cognitive abilities of adult offspring in different behavioral paradigms (exploratory (...) activity and habituation in open field tests, spatial memory in a water maze test, and aversive memory in a step-down inhibitory avoid- ance task). Results showed that maternal exercise during pregnancy increased BDNF lev- els and absolute numbers of neuronal and non-neuronal cells in the hippocampal formation of offspring. No differences in BDNF levels or cell numbers were detected in the cerebral cortex. It was also observed that offspring from exercised mothers exhibited better cognitive performance in nonassociative (habituation) and associative (spatial learning) mnemonic tasks than did offspring from sedentary mothers. Our findings indicate that maternal exer- cise during pregnancy enhances offspring cognitive function (habituation behavior and spa- tial learning) and increases BDNF levels and cell numbers in the hippocampal formation of offspring.

Autologous nerve grafts are steadily regarded as the method of choice for bridging the nerve gaps resulting after peripheral nerve lesions with substance defects. Microsurgical techniques and the perineurial suture of corresponding fascicles have improved the functional results following peripheral nerve graft. -/- However, regeneration success is often disappointing, despite the most thorough technique and expertise. The loss of spinal motoneurons associated with a nerve lesion and the growth of axon sprouts in inadequate endoneurial sheaths were held responsible as the (...) reason for the lowered muscular strength, limited movement coordination and fine motor skills, poor differentiation and localization of sensory stimuli and for the lack of tactile gnosis. -/- In this experimental study, it is assumed that the central effects at the level of the spinal motoneuron nuclei show an image of the peripheral misinnervation in topographical-morphological terms, and can supply an explanatory model for the functional motor deficits after peripheral nerve graft. -/- On the other hand, the plastic changes of a motor cell column in the reinnervation process influence the structural-functional relationships of the motor units in a variety of clinically relevant ways.

Temporal Changes in Ovarian Gonadotropin-Releasing Hormone mRNA Levels by Gonadotropins in the Rat Sung Ho Lee, Eun-Seob Song, Sun Kyeong Yu, Changmee Kim, Dae Kee Lee, Wan Sung Choi l and Kyungjin Kim* Department of Molecular Biofogy and SRC for Cell Differentiation, Seoul National University, Seoul 150-742, Korea; IDepartment of Anatomy, College of Medicine, Gyeongsanf; National University, Chinju 660-280, Korea (Recei·. cd on December 29, 1993) The present study examines whether gonadotropins are involved in the regulation of ovarian GnRH gene (...) expression and how ovarian GnRH gene expression temporalJy correlates with alterations in hypothalamic GnRH, pituitary LH~ gene expression in respons to gonadotropins. Hypothalamic and ovarian GnRH mRNA and pituitary LH~ mRNA levels were determined by respective RNA-blot hybridizations, and ovarian GnRH and estradiol contents and serum LH levels were measured by respective radioimmunoassays. Three animal models such as 1) PMSG-treated, 2) PMSG and heG-treated immature rats and 3) proestrous stage of adult rats were used. Immature rats (25-days old) were administered with PMSG (10 iu) at 10:00 hand 48 h later with heG (10 iu) to induce ovulation. In the PMSG-injected model, hypothalamic GnRH mRNA levels were markedly augmented about 9-fold at 50 h, and pituitary LH mRNA 3-fold at 52 h after PMSG administration. Serum LH levels were increased to the preovulatory surge levels at 56 h, and ovarian GnRH mRNA levels were augmented 4-fold at 60 h after PMSG injection. Administration of heG also induced a marked enhancement in ovarian GnRH mRNA levels in comparison to the values shown in both intact and PMSGtreated rats at 52 hand 54 h, respectively. In the proestrous stage of normal adult rats, pituitary LH~ mRNA levels were peaked at 16:00 h. The preovulatory LH surge was evident at 4 h before increment in ovarian GnRH mRNA levels as shown in PMSG-treated rats. The present study clearly showed the sequential increase in hypothalamic GnRH mRNA, pituitary LH~ mRNA and ovarian GnRH mRNA levels, indicating that ovarian GnRH may play a possible role in the control of follicular maturation and the ovulation process.

The present study examines the physiological alterations in prolactin (PRL) messenger ribonucleic acid (mRNA) and serum PRL levels during the rat estrous cycle and the effed of naloxone, an endogenous opioid peptide receptor antagonist, on PRL gene expression during the rat estrous cycle. Adult female rats exhibiting at least two consecutive 4-day estrous cycles were used in this study. A single injection of naloxone (2mg/kg b.w.) or saline was given sc 30 mm prior to decapitation. Animals were sacrificed at (...) 10:00 h of each stage of the estrous cycle, and at 2-h intervals from 10:00 h to 20:00 h during the proestrus. PRL mRNA and serum PRL levels were determined by an RNA-blot hybridization with the rat PRL cDNA probe and by a PRL radioimmunoassay, respectively. PRL mRNA and serum PRL levels were not dramatically altered in the morning of each stage of diestrus I, II, and proestrus, and naloxone failed to modify the two parameters. During estrus naloxone clearly suppressed serum PRL levels, but it was unable to modify PRL mRNA levels. A more detailed examination of the proestrus stage revealed that PRL mRNA and serum PRL levels fluctuated as a function of time: PRL mRNA levels reached a maximum level at 12:00 h and gradually decreased until 18:00 h. PRL mRNA levels then rose at 20:00 h. No difference in PRL mRNA levels between the control and naloxone-treated groups was observed. Changes in serum PRL level during proestrus were conversely related to changes in PRL mRNA: serum PRL levels were low from 10:00 h to 14:00 h, then increased and reached a maximum level at 16:00-18:00 h. Following then, serum PRL levels were decreased. Naloxone was effective in suppressing the characteristic afternoon surge of PRL from 16:00 h to 20:00 h. These data clearly showed that alterations in PRL mRNA levels were conversely correlated with changes in serum PRL levels on proestrus, indicating differential regulation of PRL gene expression and secretion.

Abstract. This paper illustrates how philosophy and science may converge and inform one another. I begin with a brief rehearsal of John Morreall’s “formulaic” theory of laughter, that laughter results from a pleasant psychological shift, and of my previously published criticisms and counterproposal that laughter results from titillation (where “titillation” is a semitechnical term). I defend my own position against charges that it is trivial, circular, or vacuous (charges that, if correct, would apply equally to Morreall’s position), showing that these (...) charges are misguided or premature. Then I indicate how my position is reflected in and might be given empirical content by a hypothesis that is already under preliminary experimental investigation in psychology, namely the Darwin-Hecker hypothesis, and also how my position is in harmony with recent work in psychology alleging the discovery of evolutionary antecedents of human laughter in rats.

The study of animal cognition raises profound questions about the minds of animals and philosophy of mind itself. Aristotle argued that humans are the only animal to laugh, but in recent experiments rats have also been shown to laugh. In other experiments, dogs have been shown to respond appropriately to over two hundred words in human language. In this introduction to the philosophy of animal minds Kristin Andrews introduces and assesses the essential topics, problems and debates as they cut (...) across animal cognition and philosophy of mind. She addresses the following key topics: what is cognition, and what is it to have a mind? What questions should we ask to determine whether behaviour has a cognitive basis? the science of animal minds explained: ethology, behaviourist psychology, and cognitive ethology rationality in animals animal consciousness: what does research into pain and the emotions reveal? What can empirical evidence about animal behaviour tell us about philosophical theories of consciousness? does animal cognition involve belief and concepts; do animals have a ‘Language of Thought’? animal communication other minds: do animals attribute ‘mindedness’ to other creatures? moral reasoning and ethical behaviour in animals animal cognition and memory. Extensive use of empirical examples and case studies is made throughout the book. These include Cheney and Seyfarth’s ververt monkey research, Thorndike’s cat puzzle boxes, Jensen’s research into humans and chimpanzees and the ultimatum game, Pankseep and Burgdorf’s research on rat laughter, and Clayton and Emery’s research on memory in scrub-jays. Additional features such as chapter summaries, annotated further reading and a glossary make this an indispensable introduction to those teaching philosophy of mind, animal cognition. It will also be an excellent resource for those in fields such as ethology, biology and psychology. (shrink)

We present a theory of human artistic experience and the neural mechanisms that mediate it. Any theory of art has to ideally have three components. The logic of art: whether there are universal rules or principles; The evolutionary rationale: why did these rules evolve and why do they have the form that they do; What is the brain circuitry involved? Our paper begins with a quest for artistic universals and proposes a list of ‘Eight laws of artistic experience’ -- a (...) set of heuristics that artists either consciously or unconsciously deploy to optimally titillate the visual areas of the brain. One of these principles is a psychological phenomenon called the peak shift effect: If a rat is rewarded for discriminating a rectangle from a square, it will respond even more vigorously to a rectangle that is longer and skinnier that the prototype. We suggest that this principle explains not only caricatures, but many other aspects of art. Example: An evocative sketch of a female nude may be one which selectively accentuates those feminine form-attributes that allow one to discriminate it from a male figure; a Boucher, a Van Gogh, or a Monet may be a caricature in ‘colour space’ rather than form space. Even abstract art may employ ‘supernormal’ stimuli to excite form areas in the brain more strongly than natural stimuli. Second, we suggest that grouping is a very basic principle. The different extrastriate visual areas may have evolved specifically to extract correlations in different domains , and discovering and linking multiple features into unitary clusters -- objects -- is facilitated and reinforced by direct connections from these areas to limbic structures. In general, when object-like entities are partially discerned at any stage in the visual hierarchy, messages are sent back to earlier stages to alert them to certain locations or features in order to look for additional evidence for the object . Finally, given constraints on allocation of attentional resources, art is most appealing if it produces heightened activity in a single dimension rather than redundant activation of multiple modules. This idea may help explain the effectiveness of outline drawings and sketches, the savant syndrome in autists, and the sudden emergence of artistic talent in fronto-temporal dementia. In addition to these three basic principles we propose five others, constituting a total of ‘eight laws of aesthetic experience’. (shrink)

This paper explores the relations between self-esteem and competition. Self-esteem is a very important good and competition is a widespread phenomenon. They are commonly linked, as people often seek self-esteem through success in competition. Although competition in fact generates valuable consequences and can to some extent foster self-esteem, empirical research suggests that competition has a strong tendency to undermine self-esteem. To be sure, competition is not the source of all problematic deficits in self-esteem, and it can arise for, or undercut (...) goods other than self-esteem. But the relation between competition and access to self-esteem is still significant, and it is worth asking how we might foster a desirable distribution of the latter in the face of difficulties created by the former. That is the question addressed in this paper. The approach I propose neither recommends self-denial nor the uncritical celebration of the rat race. It charts instead a solidaristic path to support the social conditions of the self-esteem of each individual. The paper proceeds as follows. I start, in section 2, by clarifying key concepts involved in the discussion. In section 3, I identify ten mechanisms that support individuals’ self-esteem and impose limits on competition. I focus, in particular, on the challenges faced by people in their practices of work. In section 4, I outline prudential and moral arguments to justify the use of the proposed mechanisms. Section 5 concludes with remarks on the role of social criticism in the processes of change implementing the mechanisms. (shrink)

The purpose of this paper is to present a general mechanistic framework for analyzing causal representational claims, and offer a way to distinguish genuinely representational explanations from those that invoke representations for honorific purposes. It is usually agreed that rats are capable of navigation because they maintain a cognitive map of their environment. Exactly how and why their neural states give rise to mental representations is a matter of an ongoing debate. I will show that anticipatory mechanisms involved in (...) rats’ evaluation of possible routes give rise to satisfaction conditions of contents, and this is why they are representationally relevant for explaining and predicting rats’ behavior. I argue that a naturalistic account of satisfaction conditions of contents answers the most important objections of antirepresentationalists. (shrink)

In this paper, I show how semantic factors constrain the understanding of the computational phenomena to be explained so that they help build better mechanistic models. In particular, understanding what cognitive systems may refer to is important in building better models of cognitive processes.

The case shows that the mechanistic account of physical computation may be (...) complemented with semantic considerations, and in many cases, it actually should. (shrink)

Most current techniques to deal with invasive species are ineffective or have highly damaging side effects. To this end suppression-drives based on clustered regularly inter-spaced short palindromic repeats (CRISPR/Cas9) have been touted as a potential silver bullet for the problem, allowing for a highly focused, humane and cost-effective means of removing a target species from an environment. Suppression-drives come with serious risks, however, such that the precautionary principle seems to warrant us not deploying this technology. The focus of this paper (...) is on one such risk – the danger of a suppression-drive escaping containment and wiping out the target species globally. Here, I argue that in most cases this risk is significant enough to warrant not using a gene-drive. In some cases, however, we can bypass the precautionary principle by using an approach that hinges on what I term the ‘Worst-Case Clause’. This clause, in turn, provides us with a litmus test that can be fruitfully used to determine what species are viable targets for suppression-drives in the wild. Using this metric in concert with other considerations, I suggest that only three species are currently possible viable targets – the European rabbit, ship rat and Caribbean Tree Frog. (shrink)

Cảm xúc là yếu tố cơ bản thúc đẩy con người đưa ra quyết định và xử lý thông tin. Sợ hãi là một trong những cảm xúc phổ biến nhất ảnh hưởng đến hành vi của nhà đầu tư cá nhân trên thị trường chứng khoán. Mặc dù nhiều nghiên cứu đã được thực hiện để khám phá tác động của nỗi sợ hãi đối với hiệu quả đầu tư và hành vi giao dịch của nhà đầu tư cá (...) nhân, nhưng vẫn còn rất ít thông tin về các yếu tố ảnh hưởng đến nỗi sợ hãi của nhà đầu tư cá nhân trong thời kỳ thị trường sụt giảm (hoặc những giai đoạn cực kỳ biến động). Vì thế, nghiên cứu này được thực hiện để tìm hiểu liệu các nguồn thông tin ảnh hưởng đến quyết định đầu tư của nhà đầu tư có ảnh hưởng đến sự sợ hãi của họ khi khủng hoảng xảy ra hay không. Nghiên cứu đã sử dụng phương pháp phân tích Bayesian Mindsponge Framework (BMF) trên bộ dữ liệu từ 1526 nhà đầu tư Trung Quốc và Việt Nam. Kết quả nghiên cứu chỉ ra rằng các nhà đầu tư tiếp cận các loại thông tin khác nhau khi đưa ra quyết định đầu tư sẽ ảnh hưởng đến tần suất phản ứng sợ hãi khác nhau. Cụ thể, các nhà đầu tư tham khảo thông tin từ chuyên gia hoặc tự phân tích khi đưa ra quyết định đầu tư ít bị đóng băng (biểu hiện của tâm lý sợ hãi) hơn trong thời kỳ thị trường sụt giảm. Ngược lại, những người đưa ra quyết định đầu tư dựa trên thông tin từ người quen hay bạn bè và trực giác sẽ bị đóng băng thường xuyên hơn. Kết quả nghiên cứu này giúp gợi ý nhà đầu tư cá nhân nên trang bị cho mình các kiến thức về tài chính cũng như tham khảo các ý kiến chuyên gia trên thị trường, hoặc những nguồn thông tin đáng tin cậy, khi đưa ra quyết định đầu tư. Bên cạnh đó, cơ quan quản lý thị trường cần có hoạt động phổ cập kiến thức về thị trường chứng khoán, hạn chế ảnh hưởng của các kênh thông tin không chính thống, và khuyến khích nhà đầu tư ít kinh nghiệm mua chứng chỉ quỹ của các quỹ đầu tư.

Im März 2020 änderte sich das Leben für viele (nicht nur in Deutschland) radikal.

The electric activities of cortical pyramidal neurons are supported by structurally stable, morphologically complex axo-dendritic trees. Anatomical differences between axons and dendrites in regard to their length or caliber reflect the underlying functional specializations, for input or output of neural information, respectively. For a proper assessment of the computational capacity of pyramidal neurons, we have analyzed an extensive dataset of three-dimensional digital reconstructions from the NeuroMorphoOrg database, and quantified basic dendritic or axonal morphometric measures in different regions and layers of (...) the mouse, rat or human cerebral cortex. Physical estimates of the total number and type of ions involved in neuronal electric spiking based on the obtained morphometric data, combined with energetics of neurotransmitter release and signaling fueled by glucose consumed by the active brain, support highly efficient cerebral computation performed at the thermodynamically allowed Landauer limit for implementation of irreversible logical operations. Individual proton tunneling events in voltage-sensing S4 protein alpha-helices of Na+, K+ or Ca2+ ion channels are ideally suited to serve as single Landauer elementary logical operations that are then amplified by selective ionic currents traversing the open channel pores. This miniaturization of computational gating allows the execution of over 1.2 zetta logical operations per second in the human cerebral cortex without combusting the brain by the released heat.

Vere Chappell has pointed out that it is not clear whether Locke has a well-developed ontology or even whether he is entitled to have one.2 Nevertheless, it is clear that Locke believes that there are organisms, and it is clear that he thinks that there are substances. But does he believe that organisms are substances? There are certainly parts of the Essay in which Locke seems unequivocally to state that organisms are substances. For instance, in 2.23.3 Locke uses men and (...) horses as examples of substances. In Locke’s most explicit the account of abstraction, given in 3.3.7-9, organism [vivens] is treated as a sub-species of body and body as a sub-species of substance; so, by transitivity, organism is a kind of substance. Finally, in his discussion of essences in 3.6, Locke uses all of the following organisms as examples of substances: horses, mules, men, sheep, goats, plants, drills, changelings, asses, bulls, cats, and rats. This textual evidence would seem to settle the matter about the ontological status of organisms. However, there are other parts of the Essay in which the ontological status of organisms is less clear, to say the least. In fact, there are texts in which Locke seems to state (or at least to be committed to the.. (shrink)

Curiosity is evident in humans of all sorts from early infancy, and it has also been said to appear in a wide range of other animals, including monkeys, birds, rats, and octopuses. The classical definition of curiosity as an intrinsic desire for knowledge may seem inapplicable to animal curiosity: one might wonder how and indeed whether a rat could have such a fancy desire. Even if rats must learn many things to survive, one might expect their learning must (...) be driven by simpler incentives, such as hunger. One might also wonder what proximal signals could guide animals towards knowledge itself, or how something as abstract as knowledge could ever be a motivational target for an unreflective animal. Taking a cue from recent work in reinforcement learning, I argue that surprise functions as a reward signal for the curious animal, and then show how this amounts to a desire for knowledge gain, where knowledge is conceived of as a cognitive adaptation to reality. This adaptation results in a mental state whose existence depends essentially on the truth of its contents, a factive mental state. Curious creatures benefit from an interaction between the prediction-error correction processes of basic learning and the active surprise-seeking force of their curiosity. This internally adversarial interaction accelerates knowledge gain in ways that are very helpful for agents with the restrictions of biological creatures, in environments with the complexity of our natural world.

Chim bói cá thường được nhắc đến qua những đoạn hội thoại đùa, mang tính sảng khoái sau các công việc nghiên cứu nghiêm túc, tức là tốn sức làm và nghĩ. Đùa vừa làm giãn tinh thần, cũng lại có thể mang đến năng lượng suy nghĩ tiếp. Cứ căng thẳng mãi sẽ rất chóng cạn kiệt sức. Vậy nên năm ngoái, mới có bài trên báo Khoa học & Phát triển.

Trong quá trình công tác, việc triển khai những thay đổi có khả năng tạo ra tiến triển tích cực với kết quả diễn ra khá thường xuyên. Một cách gọi khác khá phổ biến hiện nay là: “innovation”. Đối với lĩnh vực nghiên cứu, các “innovation” cũng có khả năng tạo ra giá trị gia tăng rất đáng kể, nhất là khi phương pháp được cải thiện. Ở một mức độ nhỏ nhưng sâu hơn, và cũng hiếm hơn, đó (...) là thay đổi/bổ sung về phương diện “khái niệm”. Hiếm là bởi không mấy khi ta có nhu cầu cải tiến một “khái niệm”. Đó là tiền đề sâu xa của những thông tin và thảo luận xây trên đó. Nếu cải tiến, bổ sung, hệ quả khá chắc chắn là có thể phải xới tung một trật tự logic của lập luận, cũng như gây ra thay đổi các khái niệm liên quan mật thiết. Tuy thế, có một trường hợp cần thay đổi: Mục tiêu nghiên cứu chính là khái niệm đó. (shrink)

I construe Relevant Alternatives Theory (RAT) as an abstract combination of anti-skepticism and epistemic modesty, then re-evaluate the challenge posed to it by the missed clue counterexamples of Schaffer. The import of this challenge has been underestimated, as Schaffer’s specific argument invites distracting objections. I offer a novel formalization of RAT, accommodating a suitably wide class of concrete theories of knowledge. Then, I introduce ‘abstract missed clue cases’ and prove that every RA theory, as formalized, admits such a case. This (...) yields an argument—in Schaffer’s spirit—that resists easy dismissal.

Đồng hành với lý thuyết MT từ 2019, tới 2023 cuốn sách Mindsponge Theory (MT) chính thức ra mắt, đánh dấu một chặng đường cá nhân tôi vừa hoàn thành các nghiên cứu tiến sỹ, vừa tìm tòi phát triển các phương pháp trợ giúp công việc hiệu quả hơn. Trên hành trình xuất hiện rất nhiều thách thức. Nhưng kỳ lạ ở chỗ khó khăn lại xuất hiện ở khái niệm tưởng như rất bé, rất cơ bản, thậm chí (...) gần như được mặc định là “đã biết”. Tôi được đồng tác giả—chính là người đã đưa ra cơ chế mindsponge—giao phó việc tiếp tục cùng phát triển ở tầng nấc sâu hơn nữa. Ông không hài lòng với nấc tưởng như đã tận cùng khi đóng gói MT là cơ chế thông tin của các hệ thống sinh học. Đây là điều rất thách thức, vì nấc tiếp theo chỉ có thể tiến hành dựa trên các thông tin khoa học từ vật lý hạt cơ bản, như dự báo của Erwin Schrödinger. Quả vậy, hành trình tìm tòi đã đi qua nhiều địa hạt của vật lý và thông tin. Hành trình này được sự hỗ trợ vô cùng hiệu quả của cuốn sách Reality is not what it seems của Rovelli cũng như On the origin of time của Hertog và bản chất thông tin của Shannon. Càng nhiều thông tin hay, những phát hiện lớn và tầng tầng lớp lớp những bộ óc thiên tài để lại cho nhân loại những kho báu kiến thức vô giá, một cá nhân lại càng cảm nhận sự nhỏ bé và hạn chế của bản thân. Tôi được thôi thúc với câu hỏi rất bé, cuối cùng hóa ra lại rất thách thức để trả lời: Vậy giá trị là gì? Cần cách tiếp cận nào để đến gần được bản chất sâu xa nhất của nó? (shrink)

European Computing and Philosophy conference, 2–4 July Barcelona The Seventh ECAP (European Computing and Philosophy) conference was organized by Jordi Vallverdu at Autonomous University of Barcelona. The conference started with the IACAP (The International Association for CAP) presidential address by Luciano Floridi, focusing on mechanisms of knowledge production in informational networks. The first keynote delivered by Klaus Mainzer made a frame for the rest of the conference, by elucidating the fundamental role of complexity of informational structures that can be analyzed (...) on different levels of organization giving place for variety of possible approaches which converge in this cross-disciplinary and multi-disciplinary research field. Keynotes by Kevin Warwick about re-embodiment of rats’ neurons into robots, Raymond Turner on syntax and semantics in programming languages, Roderic Guigo on Biocomputing Sciences and Francesco Subirada on the past and future of supercomputing presented different topics of philosophical as well as practical aspects of computing. Vonference tracks included: Philosophy of Information (Patrick Allo), Philosophy of Computer Science (Raymond Turner), Computer and Information Ethics (Johnny Søraker and Alison Adam), Computational Approaches to the Mind (Ruth Hagengruber), IT and Cultural Diversity (Jutta Weber and Charles Ess), Crossroads (David Casacuberta), Robotics, AI & Ambient Intelligence (Thomas Roth-Berghofer), Biocomputing, Evolutionary and Complex Systems (Gordana Dodig Crnkovic and Søren Brier), E-learning, E-science and Computer-Supported Cooperative Work (Annamaria Carusi) and Technological Singularity and Acceleration Studies (Amnon Eden).

Many studies on factors affecting student learning outcomes have been published, with research models that are very diverse in the number of influencing factors and the connotation of each factor. Based on a literature review and implementation of discussion and group interview methods, the author has analyzed, synthesized and proposed a general research model of factors affecting student learning outcomes and a scale of research concepts of the model. This model is the starting point for the quantitative research phase with a specific research scope depending on the needs of groups of researchers or managers.]. (shrink)

One of the ṣaḥābīs of Prophet Muḥammad is ʿUrwa b. Masʿūd from the Ṭāʾif tribe of Thaqīf. He belongs to the Ahlâf part of the Thaqīf tribe and he is the ruler of this part. ʿUrwa’s ancestry is known without any controversy until Kasî (Thaqīf). According to a narrative his epithet was Abū Yaʿfur and another of his epithet was Abū Masʿūd. Father of ʿUrwa an important person too. He is one of the leaders of his tribe and he commanded (...) his part (Aḥlāf) in wars of Fijār. Mother of ʿUrwa is Subay’a bt. ʿAbd Shams from Banū Umayya. In this way ʿUrwa has kinship both with Banū Umayya and Prophet Muḥammad. So ʿUrwa has a very important position because of his lineage, his mother and father. Thefore, his connections with Mecca and Quraysh strengthens his position. In our sources there is no information about his dates of birth and death. It is likely to be over middle age when he became a muslim, considering that he was the leader of his tribe and his son become a muslim after he died. There is too little information about weddings of ʿUrwa. According to narratives, he had ten wives before becoming Muslim. After becoming a Muslim Prophet Muḥammad warned from him to prefer four out of ten wives. One of his four wives is the daughter of Abū Sufyān. Howev-er, there is no information about the names of his wives. Names of his sons: ʿĀṣim, Abū Murra, Abū Mulayḥ, Dāwūd, Hammām and Hishām and names of his daughters: Umm Saʿīd (married with Ḥaẓrat ʿAlī) and Ḥalīma. We could see he served as embassy before the treaty of Hudaybiyah. His embassy duty shows us the superiority of his position. Also, this embassy duty was very effective at peace negotiations. He mentioned kinship relations which connects about Mecca. He said that it could be beneficial to talk to Prophet Muḥammad himself. The Meccans mentioned about their trust in ʿUrwa. During the time of his embassy, he expressed that both sides should be away from war. In this context, he told the Meccans: The people around Prophet Muḥammad are very loyal to him and he told to Prophet Muḥammad: People around him could disintegrate easily. This mission shows us he is intelligent, respectable and had high persuasion skills. ʿUrwa, observed loyalty of ṣaḥābīs to Prophet Muḥammad. He confessed this loyalty can not be for any ruler. This observa-tion probably affected ʿUrwa’s conversion to Islam. Because of the conquest of Meccah and the events that followed, the people of Ṭāʾif were very worried. Because of this reason people of Ṭāʾif took part in the side of Hawāzin’s and they bat-tled with Muslims. In this time they sent ʿUrwa b. Masʿūd and Ghaylān b. Salama to the city of D̲j̲aras̲h̲ of Yemen, to learn about some war machines and techniques. Therefore they did not join wars of Hunayn and Ṭāʾif. Prophet Muḥammad ended the siege of Ṭāʾif and went to Medina. Meanwhile, ʿUrwa and his friend returned from Yemen. According to narratives when the Prophet Muḥammad returned Medina or he was way in Medina ʿUrwa visited him and became Muslim. Some people tell about the date of ʿUrwa’s being Muslim at before or after Abū Bakr’s emirate of Hadj. However, when the narrations are examined, it can be said he became Muslim after four or five months from Prophet’s siege of Ṭāʾif and before three or four months from Tabūk expedition of Rabīʿ al-awwal or “Rabīʿ al-ākhir” (July or August) in the year 9/630. As for the conversion of ʿUrwa, basic sources report that “Allah, inspired Islam to the heart of ʿUrwa and he changed his situation. He went to the Messenger of Allah and he became Muslim.” They do not give a specific reason. But after this period the narratives tell the reason for ʿUrwa’s becoming a Muslim as due to an experience he had while travelling to Najrān for trade. In this travel, two mysterious young girls and the priest in Najrān said the last prophet came and ʿUrwa must be subject to him and ʿUrwa became Muslim after he returned. But this narrative is prob-lematic with regard to evidence and text. After being Muslim, ʿUrwa wanted permission from the Prophet to invite his tribe to accept Islam. The prophet did not want to accept this at first. Because the people of Ṭāʾif had an arro-gant stance against Islam, and he said that the people of Thaqīf could kill ʿUrwa. Eventually ʿUrwa went to his hometown with permission of Prophet and invited people to Islam and they did not accept this invitation and cursed ʿUrwa. The next morning ʿUrwa read adhan of fajr and people of Ṭāʾif killed him. ʿUrwa b. Masʿūd was likened to Prophet Jesus by the Prophet Muḥammad. It is generally accept-ed that ʿUrwa b. Masʿūd el-Thaqafī is “one of the biggest from two cities” expressed in sūra Zukhruf. Only two weak narrations were reported of Urwa who could live as a Muslim for a few days and was matyred by his tribe. (shrink)

The Zhuangzi 莊子 depicts persons as surviving their deaths through the natural transformations of the world into very different forms—such as roosters, cart-wheels, rat livers, and so on. It is common to interpret these passages metaphorically. In this essay, however, I suggest employing a “Conventionalist” view of persons that says whether a person survives some event is not merely determined by the world, but is partly determined by our own attitudes. On this reading, Zhuangzi’s many teachings urging us to embrace (...) transformation are not merely a psychological aid for dealing with death, but also serve as a tool for literally surviving it.

Công việc nghiên cứu khoa học hẳn nhiên có rất nhiều chi phí. Việc phân loại chi phí cũng có thể gọi là cả một ngành khoa học hẹp được. Nhưng có những chi phí không tên. Hơn thế nữa, trong chi phí không tên có cả những chi phí chẳng mấy ai buồn quan tâm.

Mấy ngày tuần qua, có nhiều ý kiến xung quanh chuyện đọc sách của Hoa hậu Kỳ Duyên. Nhiều chê bai, cũng có ý kiến bày tỏ sự thông cảm với lựa chọn cá nhân. Một số ý kiến cho rằng cần phải tăng cường truyền cảm hứng cho văn hóa đọc [1]. Tuy vậy, tình trạng văn hóa đọc suy giảm hoàn toàn không mới. Ngay cả ở những quốc gia có tầm ảnh hưởng và độ sâu văn hóa (...) rất đáng kính trọng như Pháp, đọc sách cũng đang bị suy giảm trong giới trẻ [2]. Sự cạnh tranh của các loại hình thông tin, thiết bị công nghệ và dịch chuyển từ "đọc sang xem" và "xem sang xem lướt" đã góp phần tạo nên sự xói mòn nền tảng đọc. Trên thực tế, từ phương diện sinh học, đọc tốn năng lượng, phải suy nghĩ và ngốn nhiều thời gian. Cân nhắc đánh đổi thói quen thụ hưởng lợi ích nhanh lấy lợi ích lâu dài trở thành khó khăn hơn ở thời đại này. So với thời kỳ khi mà sách là một trong số ít phương tiện thông tin mang lại nhiều lợi ích tinh thần, cân nhắc này rõ ràng thiệt thòi cho văn hóa đọc. Tuy vậy, cũng không cần quá bi quan, vì trong một số cộng đồng hướng tới phát triển nền tảng tri thức lâu bền, văn hóa đọc sẽ vẫn tiếp tục được duy trì, thậm chí phát triển. Hình ảnh tình cờ tôi thấy dưới đây là một ví dụ. (shrink)

This (1982) essay sets out the claim that psychoanalysis is a cogent extension of the intuitive common sense psychology by which we naturally understand human action. In this psychology explanation proceeds by relating actions to the logically and causally cohering desires and beliefs of agents. As Freud showed, this kind of explanation is systematically deepened and extended by the explanation of dreams, the symptoms of mental disorder, and other related phenomena via the Freudian concept of wish fulfilment, which was later (...) extended to the more inclusive post-Freudian concept of phantasy. In this extension everyday actions, such as Freud's writing up his patient Irma's case history on the day before his dream of Irma's injection, are seen to be rooted in the same unconscious motives as are represented as fulfilled in dreams and symptoms -- e.g., in this case, by unconscious stirrings of deep guilt on the topic of injection, of which Freud was unaware until he analysed the dream. As this illustrates, the understanding of wishfulfilments and other formations of phantasy enables us fill out our account of agents and their actions by adding a stock of previously unacknowledged desires and modes of expression of desire. These are seen to cohere with, and also to deepen, our previous understanding: after understanding Freud's dream, we also have a deeper and firmer (and so more cogent) understanding of his behaviour on the previous day. In this way Freud effected an extension of our everyday mode of understanding that was cogent, cumulative, and radical, as illustrated further by examination of Freud's case history of the patient described as the Rat Man.
