Functional independence within the self-memory system: new insights from two cases of developmental amnesia.

Neuropsychological and neuroimaging data suggest that the self-memory system can be fractionated into three functionally independent systems processing personal information at several levels of abstraction, including episodic memories of one's life (episodic autobiographical memory, EAM), semantic knowledge of facts about one's life (semantic autobiographical memory, SAM), and semantic knowledge of one's personality [conceptual self, (CS)]. Through the study of two developmental amnesic patients suffering of neonatal brain injuries, we explored how the different facets of the self-memory system develop when growing up with bilateral hippocampal atrophy. Neuropsychological evaluations showed that both of them suffered from dramatic episodic learning disability with no sense of recollection (Remember/Know procedure), whereas their semantic abilities differed, being completely preserved (Valentine) or not (Jocelyn). Magnetic resonance imaging, including quantitative volumetric measurements of the hippocampus and adjacent (entorhinal, perirhinal, and temporopolar) cortex, showed severe bilateral atrophy of the hippocampus in both patients, with additional atrophy of adjacent cortex in Jocelyn. Exploration of EAM and SAM according to lifetime periods covering the entire lifespan (TEMPAu task, Piolino et al., 2009) showed that both patients had marked impairments in EAM, as they lacked specificity, details and sense of recollection, whereas SAM was completely normal in Valentine, but impaired in Jocelyn. Finally, measures of patients' CS (Tennessee Self-Concept Scale, Fitts and Warren, 1996), checked by their mothers, were generally within normal range, but both patients showed a more positive self-concept than healthy controls. These two new cases support a modular account of the medial-temporal lobe with episodic memory and recollection depending on the hippocampus, and semantic memory and familiarity on adjacent cortices. Furthermore, they highlight developmental episodic and semantic functional independence within the self-memory system suggesting that SAM and CS may be acquired without episodic memories.

The political economy of international regulatory convergence in public utilities

To what extent should public utilities regulation be expected to converge across countries? When it occurs, will it generate good outcomes? Building on the core proposition of the New Institutional Economics that similar regulations generate different outcomes depending on their fit with the underlying domestic institutions, we develop a simple model and explore its implications by examining the diffusion of local loop unbundling (LLU) regulations. We argue that: one should expect some convergence in public utility regulation but with still a significant degree of local experimentation; this process will have very different impacts of regulation.

Local perception and use of the multifunctionality of water tanks in two villages of Tamil Nadu, South India

Using data from free listings and a survey in two villages of Tamil Nadu, India, we discuss local perceptions and uses of water tanks, a traditional irrigation infrastructure. We hypothesize that both farmers and nonfarmers perceive and use water tanks for purposes other than irrigation. We found that informants recognized the importance of water tanks for irrigation, but also acknowledged other socioeconomic uses and ecological functions. Marginal sectors (i.e., Scheduled Castes) use tank resources in more diverse ways than other sectors of the population. Findings are relevant for development. International organizations working on the revival of water tanks aim to transfer water management to farmers for the purpose of irrigation. By recognizing that tanks benefit people other than farmers and in ways other than providing irrigation water, organizations working on tank rejuvenation could achieve a more equitable management of tank resources.

How Important to a City Are Tourists and Daytrippers? The Economic Impact of Tourism on The City of Barcelona

In this paper, we devise a methodology that is able to objectively quantify the impact of tourism on the urban economy. This methodology takes various dimensions into account. First, to analyse the impact at sectoral level, it should bear in mind that tourism is a cross-sectional activity which affects many sectors, both directly and indirectly. Therefore, it is important to consider the impact of urban tourism on sectors traditionally defined as tourism-related, -that is, hotels, restaurants, shops, etc.- but also its impact on other sectors -for instance, textiles, food, construction, to name only a few- due to the intersectoral relationships that emerge. Second, we need to calculate the percentage of the turnover of each sector that is due to the tourism industry. Third, it is important to establish the geographic distribution of this impact: how is the effect shared between the city and its neighbouring areas QUESTION Finally, the effect of urban tourism should be quantified not only in terms of turnover, but also in terms of its contribution to GDP and employment.

Coexistence of Two Kinds of Fluorinated Hydrogenated Micelles as Building Blocks for the Design of Bimodal Mesoporous Silica with Two Ordered Mesopore Networks

A simple and effective route has been developed for the synthesis of bimodal (3.6 and 9.4 nm) mesoporous silica materials that have two ordered interconnected pore networks. Mesostructures have been prepared through the self assembly mechanism by using a mixture of polyoxyethylene fluoroalkyl ether and triblock copolymer as building block. The investigation of the RF8(EO)9/P123/water phase diagram evidences that in the considered surfactant range of concentrations, the system is micellar (L1). DLS measurements indicate that this micellar phase is composed of two types of micelles, the size of the first one at around 7.6 nm corresponds unambiguously to the pure fluorinated micelles. The second type of micelles at higher diameter consists of fluorinated micelles which have accommodated a weak fraction of P123 molecules. Thus, in this study the bimodal mesoporous silica are really templated by two kinds of micelles.

Characterization of soil parameters of two soils of Rio Grande do Sul in modeling the prediction of tractive effort

The interaction between the soil and tillage tool can be examined using different parameters for the soil and the tool. Among the soil parameters are the shear stress, cohesion, internal friction angle of the soil and the pre-compression stress. The tool parameters are mainly the tool geometry and depth of operation. Regarding to the soils of Rio Grande do Sul there are hardly any studies and evaluations of the parameters that have importance in the use of mathematical models to predict tensile loads. The objective was to obtain parameters related to the soils of Rio Grande do Sul, which are used in soil-tool analysis, more specifically on mathematical models that allow the calculation of tractive effort for symmetric and narrow tools. Two of the main soils of Rio Grande do Sul, an Albaqualf and a Paleudult were studied. Equations that relate the cohesion, internal friction angle of the soil, adhesion, soil-tool friction angle and pre-compression stress as a function of water content in the soil were obtained, leading to important information for use of mathematical models for tractive effort calculation.

Waste Management in Commercial Activity: State-of-the-Art and the Potential Innovation in the Urban Areas of Hanoi, Vietnam

As the rapid development of the society as well as the lifestyle, the generation of commercial waste is getting more complicated to control. The situation of packaging waste and food waste – the main fractions of commercial waste in different countries in Europe and Asia is analyzed in order to evaluate and suggest necessary improvements for the existing waste management system in the city of Hanoi, Vietnam. From all waste generation sources of the city, a total amount of approximately 4000 tons of mixed waste is transported to the composting facility and the disposal site, which emits a huge amount of 1,6Mt of GHG emission to the environment. Recycling activity is taking place spontaneously by the informal pickers, leads to the difficulty in managing the whole system and uncertainty of the overall data. With a relative calculation, resulting in only approximately 0,17Mt CO2 equivalent emission, incinerator is suggested to be the solution of the problem with overloaded landfill and raising energy demand within the inhabitants.

Paradoxical increase of exploratory behavior in the elevated plus-maze by rats exposed to two kinds of aversive stimuli

Albino rats were submitted to a 24-h period of social isolation (individual housing) combined with 0, 1, 2 or 3 twenty-four-hour periods of exposure to different vivaria (novelty) and tested in the elevated plus-maze. Results, reported as mean ± SEM for N = 12, show that the time (in seconds) spent in the open arms by rats exposed to novelty for 0, 1, 2 and 3 days was 28.3 ± 4.4, 31.6 ± 3.2, 29.1 ± 3.5 and 25.0 ± 3.3, respectively, when grouped in the same vivarium; 29.6 ± 2.7, 7.6 ± 2.1, 9.6 ± 4.4 and 28.5 ± 3.7 when grouped in different vivaria; 2.9 ± 1.1, 1.8 ± 1.0, 2.7 ± 1.1 and 0 ± 0 when isolated in the same vivarium, and 2.6 ± 1.1, 31.5 ± 8.2, 24.8 ± 4.2 and 0 ± 0 when isolated in different vivaria. The number of entries into the open and closed arms followed a similar trend. This indicates that, separately, both exposure to novelty and isolation are aversive manipulations. Paradoxically, when novelty was combined with a concomitant 24-h period of social isolation prior to testing, the decrease in exploratory behavior caused by either of the two aversive manipulations alone was reverted. These results are indicative that less intense anxiety triggers mechanisms mediating less energetic behavior such as freezing, while higher levels trigger mechanisms mediating more vigorous action, such as flight/fight behavior, since the combination of two aversive situations resulted in more exploratory behavior than with either alone. They are also suggestive of habituation to the effects of novelty, since exposure to it for 3 days produced exploratory behavior similar to that of controls

Interaction on the Page: Paratexts in two manuscripts of the Middle English Polychronicon

Tutkimuksessani tarkastelen myöhäiskeskiaikaisen maailmanhistoriateoksen, Ranulph Higdenin Polychroniconin, materiaalisia ilmentymiä. Vertailuun valittiin kaksi käsikirjoitusta, jotka sisältävät John Trevisan keskienglanninkielisen käännöksen kyseisestä teoksesta. Tutkielman lähtökohtana on ajatus, jonka mukaan käsikirjoitusten ja painettujen kirjojen välisistä eroista huolimatta myös ensin mainittuja voidaan tutkia kirjoina eli lukijan kohtaamina fyysisinä esineinä, jotka sisältävät varsinaisen tekstin lisäksi tekstuaalisia ja visuaalisia elementtejä, joilla tekstiä jäsennellään ja esitellään lukijalle ja jotka vaikuttavat lukijan lukukokemukseen ja ohjaavat lukuprosessia. Näiden elementtien kuvaamiseen ja analysointiin olen soveltanut Gérard Genetten parateksti-käsitettä, jonka käyttö käsikirjoitusten tutkimuksessa on toistaiseksi ollut vähäistä. Tutkielman tavoitteena on historiallisen pragmatiikan mukaisesti ottaa huomioon tekstien fyysinen ja sosiaalinen konteksti. Näkökulma painottuu vuorovaikutukseen kirjan tuottajien ja sen lukijoiden välillä, ja tutkielman tarkoitus on paitsi selvittää, millaisia elementtejä käsikirjoituksista löytyy lukijan lukuprosessia ohjaamaan ja tukemaan, myös tarkastella lukijoiden itsensä tekemiä merkintöjä. Tutkimustulokset osoittavat, että lukijoiden merkinnät noudattelivat osin samoja muotoja ja käyttötarkoituksia kuin kirjurien valmiiksi täydentämät elementit (esim. glossat) käsikirjoituksissa, mutta joitakin elementtejä täydennettiin mahdollisesti myös painettujen kirjojen myötä yleistyneiden käytäntöjen pohjalta. Analyysissani tarkastelen lähemmin myös teokseen liitettyjä esipuheita ja muita tekstejä tarkoituksenani selvittää, mitkä niistä voidaan luokitella parateksteiksi ja mikä merkitys niillä on kokonaisuuden kannalta. Tutkimuksessa kävi ilmi, että tekijän ja kääntäjän esipuheista löytyivät kaikki Genetten määrittämät kriteerit, kun taas aineiston toiseen käsikirjoitukseen sisältyvät muiden kirjoittajien tekstit eivät ole luokiteltavissa parateksteiksi, vaikka ne ulkoisesti sellaisilta vaikuttavat ja vaikka niistä on tullut paratekstien kaltainen kiinteä osa Polychroniconia.

The real mechanisms of the global economy

The paper presents the main arguments of Bresser Pereira's Globalization and Competition. Development strategies based on the 'conventional orthodoxy' are shown to carry serious drawbacks ("Dutch disease", pernicious effects of external saving, currency overvaluation), while a 'new developmentalism' is promoted, in spite of the widespread belief that the nation-states have been dispossessed of their room for manoeuvre because of the globalization process. The "new developmentalism" is based on domestic finance, balanced public budgets, moderate interest rates and competitiveness policies aimed at neutralizing the tendency to exchange rate overappreciation. The paper also points out a few theoretical questions the book raises.

Update analysis on the international crisis and its impact on the Mexican economy

The aim of this study is to analyze the current state of the Mexican economy in the face of the international crisis. Two questions are asked: Is the international crisis over? Is the Mexican economy strong and resilient enough to face the crisis in the eurozone? The first of these questions is answered in the first part. The answer to the second question is discussed in the second part of this study. Also examined are the large number of short, medium and long term problems that the Mexican economy will have to face in 2012 and perhaps 2013.
