The Explanatory Indispensability of Memory Traces

During the first half of the twentieth century, many philosophers of memory opposed the postulation of memory traces based on the claim that a satisfactory account of remembering need not include references to causal processes involved in recollection. However, in 1966, an influential paper by Martin and Deutscher showed that causal claims are indeed necessary for a proper account of remembering. This, however, did not settle the issue, as in 1977 Malcolm argued that even if one were to buy Martin and Deutscher’s argument for causal claims, we still don’t need to postulate the existence of memory traces. This paper reconstructs the dialectic between realists and anti-realists about memory traces, suggesting that ultimately realists’ arguments amount to inferences to the best explanation. I then argue that Malcolm’s anti-realist strategy consists in the suggestion that causal explanations that do not invoke memory traces are at least as good as those that do. But then, Malcolm, I argue that there are a large number of memory phenomena for which explanations that do not postulate the existence of memory traces are definitively worse than explanations that do postulate them. Next, I offer a causal model based on an interventionist framework to illustrate when memory traces can help to explain memory phenomena and proceed to substantiate the model with details coming from extant findings in the neuroscience of memory

Know-how, intellectualism, and memory systems

ABSTRACTA longstanding tradition in philosophy distinguishes between knowthatand know-how. This traditional “anti-intellectualist” view is soentrenched in folk psychology that it is often invoked in supportof an allegedly equivalent distinction between explicit and implicitmemory, derived from the so-called “standard model of memory.”In the last two decades, the received philosophical view has beenchallenged by an “intellectualist” view of know-how. Surprisingly, defenders of the anti-intellectualist view have turned to the cognitivescience of memory, and to the standard model in particular, todefend their view. Here, I argue that this strategy is a mistake. As it turns out, upon closer scrutiny, the evidence from cognitivepsychology and neuroscience of memory does not support theanti-intellectualist approach, mainly because the standard modelof memory is likely wrong. However, this need not be interpretedas good news for the intellectualist, for it is not clear that theempirical evidence necessarily supp..

Ultrasonographic identification of the dorsal atlantoaxial ligament in dogs

Objective: To determine the ability to identify the dorsal atlantoaxial ligament during ultrasonographic examination of dogs. Study design: Canine cadaveric study. Sample population: Canine cervical spines (n = 35). Methods: Thirty-five canine cadavers with an estimated body weight of 6-35 kg were retrieved. Five cervical spines were dissected to assess the length and thickness of the dorsal atlantoaxial ligament and correlate ultrasound-guided injection of ink with anatomical dissection. Ultrasonographic evaluation of the dorsal atlantoaxial ligament was performed on 30 cadavers. The visibility of the dorsal atlantoaxial ligament in both the transverse and the sagittal planes was subjectively scored (0-3). Results: The dorsal atlantoaxial ligament was detectable on ultrasonographic examination in all cadavers: 27/30 and 28/30 were graded as moderately visible (grade 2) or clearly visible (grade 3) in the sagittal and transverse view, respectively. Only 1/30 cadaver specimen of a large breed dog was graded as 1 (indistinct) in both the sagittal and transverse planes. None of the cadavers were graded as 0 (not visible) in any view. Conclusion: The dorsal atlantoaxial ligament can be identified in ultrasonographic examination of normal canine cadavers. Future studies on animals with clinical atlantoaxial instability/subluxation are needed to evaluate the role of this imaging technique in providing a safer diagnosis of this condition. Clinical relevance: Ultrasonographic examination of the dorsal atlantoaxial ligament could potentially provide a noninvasive and safe imaging technique that may contribute to the diagnosis of atlantoaxial instability/subluxation in dogs

How costly is rent-seeking to diversification : an empirical approach

The empirical U-shaped pattern between product diversification and economic development has been widely examined, but here we analyze the determinants of diversification. We find that a high level of rent-seeking activities has a large impact on the diversification of nations : in countries where rent-seeking is a widespread practice, the number of products being exported will be smaller and its value more concentrated in certain goods. Our analysis embraces a large sample of more than 130 countries between 1995 and 2007, using a highly disaggregated export database comprising more than 5000 products. To establish this relationship, we use a Generalized Method of Moments estimation, controlling for endogeneity originated from reverse causality. These empirical predictions contribute to the idea that resources allocated to harm diversification are an important binding constraint for developing countries.Product diversification, international trade, economic development.

New products and corruption: evidence from Indian firms

It has been shown that corruption has a negative effect on firm productivity, but what about its impact on product innovation ? We find that corruption, functioning as a bribe tax, diminishes the probability of new product introduction. We use a World Bank Enterprise Survey from India in 2005, with 1600 firms answering if they introduced a new product to the firm and on the average quantity of bribe paid by firms. Controlling for innovation determinants, firm characteristics, location choice, multi-product firms and other business environment variables, sector-location bribe averages have a negative and significant impact on product innovation.Innovation, corruption, firm performance.

A Role for the prefrontal cortex in supporting singular demonstrative reference

One of the most pressing questions concerning singular demonstrative mental contents is what makes their content singular: that is to say, what makes it the case that individual objects are the representata of these mental states. Many philosophers have required sophisticated intellectual capacities for singular content to be possible, such as the possession of an elaborate scheme of space and time. A more recent reaction to this strategy proposes to account for singular content solely on the basis of empirical models of visual processing. We believe both sides make good points, and offer an intermediate way of looking into singular content. Our suggestion is that singular content may be traced to psychological capacities to form flexible, abstract representations in the prefrontal cortex. This allows them to be sustained for increasingly longer periods of time and extrapolated beyond the context of perception, thus going beyond lowlevel sensory representations while also falling short of more sophisticated intellectual abilities

Uncertainty in Spanish Organic Products: A Global Analysis from Consumer to Entrepreneurs

The organic market is a very particular one. Starting from the premise that organic products are confidence and credibility products which cannot be easily differentiated from the rest, we find that consumers face a risk when purchasing them. In Spain, the marketing chain does not follow the conventional stages in most of the cases, so there is always some uncertainty about how the products will be sold. In addition, the great majority of the Spanish organic production is marketed abroad. In this paper we show some of the results of an investigation project in this topic.Organic, risk, chain, producer, consumer, Agribusiness, Risk and Uncertainty,

Challenge to SME to Survive in Food Dynamic Markets: Innovation and Efficient Networks

The EU food entrepreneurs are facing dramatic changes in the competition arena. Globalization and liberalization processes are offering cheaper food products in international markets, either from countries with better comparative advantages or with more efficient marketing strategies. At the same time, food markets are in a process of continuous segmentation and changes. Consumers are located in different niches, according to socio-demographic variables, cultures and traditions. Some of them respond to price changes while others are more concerned with quality control and food safety. It is on this segment where typical products, traceability and denominations of origin have significant values. SME (Small and Medium Enterprises) have to survive on this competitive scenario using several strategies: focusing their attention on specific consumer segments (aged people, gourmets or ethnic groups), products (typical, denomination of origin) or with more personal attention. Their flexibility to adapt the production process should compensate the lack of economic and human resources and specialization activities. In the 21st century they may survive through adequate strategies, most of them based on several pillars: innovation, tradition and adequate network.Agribusiness, Industrial Organization, Marketing,

Copper, the Real Exchange Rate and Macroeconomic Fluctuations in Chile

This paper examines the impact of the copper price on macroeconomic performance in Chile. We explore particular features of the Chilean business cycle focusing on economic activity and the real exchange rate. We find that the Chilean economy has become increasingly resilient to copper price shocks in the last twenty-five years, and especially during this last decade. The evidence shows that output volatility has dramatically decreased over the last twenty years, and the contribution of copper price fluctuations to output volatility has also declined. Moreover, the real exchange rate has acted as a shock absorber, and although during the last decade its short-run volatility has increased, its longrun volatility has remained stable and more recently has slightly declined. The decliningimpact of copper prices on the business cycle is due to macroeconomic policies. The evidence shows that a flexible exchange rate, a rule-based fiscal policy, and a flexible inflation targeting regime play a central role in these results.
