Mental time travel and the philosophy of memory

The idea that episodic memory is a form of mental time travel has played an important role in the development of memory research in the last couple of decades. Despite its growing importance in psychology, philosophers have only begun to develop an interest in philosophical questions pertaining to the relationship between memory and mental time travel. Thus, this paper proposes a more systematic discussion of the relationship between memory and mental time travel from the point of view of philosophy. I start by discussing some of the motivations to take memory to be a form of mental time travel. I call the resulting view of memory the mental time travel view. I then proceed to consider important philosophical questions pertaining to memory and develop them in the context of the mental time travel view. I conclude by suggesting that the intersection of the philosophy of memory and research on mental time travel not only provides new perspectives to think about traditional philosophical questions, but also new questions that have not been explored before. Keywords: mental time travel, memory, episodic memory, philosophy of memory.
NEUROLETCTINS: BIOCHEMICAL CHARACTERISATION AND FUNCTIONS

The presented work deals with the recent achievements in the field of research of neurolectins, their quantitative and qualitative distribution in cerebral cells of different animals, subcellular structures and synaptosomes in relation to embryonic development. Distribution of neurolectin-binding receptors glycoproteins and glycolipids in the same structures, their role in the processes of migration of neurons and other mechanisms are studied as well. Two membrane neurolectins VL-1 and VL-NAGA have been revealed in synaptosomes, which according to our hypothesis are actively involved in absorption and secretion of neurotransmitters. It was established that VL-1, located on the outer membrane of synaptosomes participates in absorption and metabolism of biologically active substances, though VL-NAGA, which is located in the inner side of the membrane is also involved in their metabolism. It is considered that negative effects of wheat germ agglutinin (WGA) lectins, among them neurotoxic, cardiotoxic and immunotoxic, can be avoided by means of well toasted bread, because in the process of toasting lectins undergo denaturation and lose their toxic activity. Food should be chewed well, until it becomes saturated with glycoprotein mucine, which is component of saliva, as N-acetyl-D-glucosamine binding and inactivating WGA is presented in its active centre. In conclusion it is said that uptake of food additives offered by D’Adamo, with the ability of binding WGA and other neurolectins, is not recommended for teenagers and pregnant women, as they may cause inhibition of key processes, involved in mechanisms of structural-functional organization of brain.
Etude des propriétés hydriques et des mécanismes d'altération de pierres calcaires à forte porosité

L'objectif principal de cette these concerne l'etude, par une approche multi-echelles, du comportement des pierres de monuments vis-a-vis de l'alteration. A cet effet, deux pierres de construction, dont certaines caracteristiques principales sont assez semblables (porosite totale, resistance mecanique), sont etudiees : le tuffeau blanc, qui est largement employe dans les constructions des châteaux du Val de Loire, et la pierre de Sebastopol, utilisee en region parisienne. Tout d'abord, une observation des differents types de degradations rencontrees in-situ ainsi qu'une etude de cas sur une pierre alteree naturellement ont ete realisees afin de constater les differentes morphologies d'alteration et d'identifier l'eau comme l'agent vecteur des phenomenes d'alteration. Dans un second temps, une caracterisation multi-echelles a ete effectuee afin de bien connaitre les pierres non-alterees du point de vue de leur constitution mineralogique, de la morphologie de leur milieu poreux et surtout de leurs proprietes hydriques (capacite de retention d'eau, proprietes de transfert de l'eau sous forme liquide et sous forme vapeur) mais aussi de leur comportement hydro-mecanique. La derniere partie est consacree a la durabilite des pierres mises en oeuvre avec l'etude de la compatibilite entre les materiaux utilisees en restauration. En effet, le comportement des pierres durant un essai de vieillissement artificiel est compare. La reaction differente des deux pierres face a ce meme processus d'alteration est a relier directement a leurs proprietes hydriques tres dissemblables. En dernier lieu, une formulation et une caracterisation hydro-mecanique de joints de mortier est proposee afin de determiner les criteres de compatibilite entre le mortier et les pierres en oeuvre.
An Algorithmic Study of the Machine Reassignment Problem

In this work, an approach to solve the Machine Reassignment Problem is proposed. The problem consists in optimizing the usage of computational resources given a set of processes that must be executed. Therefore, an assignment of processes to machines must be find. Besides, there are plenty of constraints for increasing safety and reliability of the system. The problem has an important practical relevance nowadays. The increasing usage of cloud computing concepts forces the resource optimization of these huge computational infrastructures. This is a very complex NP-Hard combinatorial optimization problem. Thus, the choice of an heuristic method is natural for solving the problem approximately. The proposed solution is an heuristic based on Simulated Annealing that uses two neighborhoods. The results are satisfactory since near-optimal solutions are found in less than five minutes. Besides the proposed algorithm, this work presents some other contributions. An integer programming formulation is proposed and implemented, being capable of finding optimal solutions for small instances of the problem. To evaluate the solutions found by the proposed method for big instances, a lower bound was developed. The lower bounds seem to be good approximations of the optimal solutions in most cases. The Machine Reassignment Problem was proposed in the context of the ROADEF / EURO Challenge, an international challenge proposed by the French Society of Operations Research. The presented problems always are important in Industry. This year, Google proposed the problem, interested in methods for optimizing its computational infrastructure. Among 83 participating teams, 30 have been classified for the final phase, and our team (representing UFRGS) ranked fourth with a preliminary version of the proposed method. The final results are not yet published as of the publication date of this work.
Towards Multi-Pixel Heterodyne Terahertz Receivers

Terahertz multi-pixel heterodyne receivers introduce multiple challenges for their implementation, mostly due to the extremely small dimensions of all components and even smaller tolerances in terms of alignment, linear dimensions and waveguide component surface quality. In this manuscript, we present a concept of terahertz multi-pixel heterodyne receiver employing optical layout using polarization split between the LO and RF. The frontend is based on a waveguide balanced HEB mixer for the frequency band 1.6 – 2.0 THz. The balanced HEB mixer follows the layout of earlier demonstrated APEX T2 mixer. However for the mixer presented here, we implemented splitblock layout offering minimized lengths of all waveguides and thus reducing the associated RF loss. The micromachining methods employed for producing the mixer housing and the HEB mixer chip are very suitable for producing multiple structures and hence are in-line with requirements of multi-pixel receiver technology. The demonstrated relatively simple mounting of the mixer chip with self-aligning should greatly facilitate the integration of such multi-channel receiver.
Quasilocal conformal Killing horizons: Classical phase space and the first law

In realistic situations, black hole spacetimes do not admit a global timelike Killing vector field. However, it is possible to describe the horizon in a quasilocal setting by introducing the notion of a quasilocal boundary with certain properties which mimic the properties of a black hole horizon. Isolated horzons and Killing horizons are examples of such kind. In this paper, we construct a boundary of spacetime which is null and admits a conformal Killing vector field. Furthermore we construct the space of solutions (in general theory of relativity) which admits such quasilocal conformal Killing boundaries. We also establish a form of first law for these quasilocal horizons.
Virus Adaptation and Treatment Oncolytic viruses : a step into cancer immunotherapy

Oncolytic viruses (OVs) selectively infect, replicate in, and kill tumor cells. For a long time, the therapeutic efficacy was thought to depend on the direct viral oncolysis (virocentric view). The host immune system was considered as a brake that impaired virus delivery and spread. Attention was paid primarily to approaches enhancing virus tumor selectivity and cytotoxicity and/or that limited antiviral responses. Thinking has changed over the past few years with the discovery that OV therapy was also inducing indirect oncolysis mechanisms. Among them, induction of an antitumor immunity following OV injection appeared to be a key factor for an efficient therapeutic activity (immunocentric view). Indeed, tumor-specific immune cells persist post-therapy and can search and destroy any tumor cells that escape the OVs, and thus immune memory may prevent relapse of the disease. Various strategies, which are summarized in this manuscript, have been developed to enhance the efficacy of OV therapy with a focus on its immunotherapeutic aspects. These include genetic engineering and combination with existing cancer treatments. Several are currently being evaluated in human patients and already display promising efficacy.
Assessing the Accessibility of the Homeownership Market

In this paper, an examination is made of the accessibility of the homeownership market using measures that include both supply and demand characteristics of regional housing markets. These measures are applied empirically on an extensive dataset that covers the Dutch housing market. The analysis quantifies the extent to which the position of first-time buyers on the homeownership market has weakened over time and identifies the driving factors of this change. It is found that smaller portions of the housing market are becoming affordable due to financial constraints of young households. However, more importantly, first-time buyers today need to contend with a much larger group of competing bidders on every house that suits their financial situation, than ever before.

SUSTAINABLE CONCRETE ROOF TILES CONTAINING RECYCLED GLASS

The final disposal route of post-consumer recycled glass (RG) is a common issue for many municipalities worldwide. Approximately 1 million tons of glassware is produced per year in Brazil, only 47% of which are currently recycled. The idea of incorporating RG as aggregate for concrete emerged in the 60´s motivated by some of the advantages of glass, i.e. low water absorption, high abrasion and durability, aesthetic potential among others. However, the initial researches have shown that concretes containing RG exhibited marked strength regression and excessive expansion due to alkali-aggregate reaction (ASR), which limited further research. The topic emerged again in the 90´s, imposed by the sustainability issues. Moreover, new studies aimed to determine the conditions at which ASR does not occur, as well as the influence of RG on the physical properties of concrete. Despite some literature on the use of RG into concrete, its application for making concrete roof tiles is still not documented. The incorporation of RG into those products, if feasible, may create a sustainable material for construction by reducing the land-filling of RG in
ALIANÇAS MERCADOLÓGICAS : A BUSCA DA COORDENAÇÃO NA CADEIA DE GADO DE CORTE BRASILEIRA

The restructuring of the beef chain in Brazil has been taken under several public and private institutional actions, not rarely a joint action. However, there is a large number of agents in each chain-link of the beef chain in Brazil, resulting in conflicts of objectives, lack of hegemonic organisations and difficulties to meet common solutions for the chain problems. It is in this context of lack of more efficient co-ordination that experiences of marketing alliances emerges, where farmers, slaughterhouses and retailers operate co-operatively, trying to attract consumers.

Building the Resilient Supply Chain

In today's uncertain and turbulent markets, supply chain vulnerability has become an issue of significance for many companies. As supply chains become more complex as a result of global sourcing and the continued trend to “leaning‐down”, supply chain risk increases. The challenge to business today is to manage and mitigate that risk through creating more resilient supply chains.
Reflections and dilemmas on HIV/AIDS and condom use among young adults in Akuse, Ghana

The study area Akuse, has been stigmatized with the Issue of HIV/AIDS and the community has vehemently denied the statistics on HIV case provided by the Ghana AIDS commission. I therefore sought permission from the community authorities that my research was for only academic purpose which will not be made public by showing them a proof of my introduction letter i took from my supervisor. Publishing this document would stir-up the already existing conflicts between the community and the national authorities on HIV/AIDS. I therefore need to abide by the consent of the community authorities. I e-post 08.08. 2012 har kandidaten bedt om at oppgaven publiseres likevel. UB/IFU/JEF
Making infrastructure work for the poor: Development benefits of PV systems in two Bangladesh communities

Bangladesh has been suffering from acute shortages of energy and the gap between demand and supply of ener gy has been gradually increasing. As the country has very limited natural resources, except natural gas, it largely depends on imported fuel. But due to financial and technical inability, it is almost impossible for Bangladesh to extend fossil fuel based power distribution networks to the rural community. Moreover, the low purchasing power is also a limiting factor for the rural population to have access to the formal energy market. As a result, rural society is in a most vulnerable situation from the side of energy consumption. Against this background, this study aims to examine the link between energy and economic development by collecting primary data from two Bangladesh communities which use solar energy. The study made an attempt to find out the economic and social impacts of sustainable rural energy on poor people and governance and management of these infrastructure projects. The study found that providing electricity through solar energy has a multidimensional affect on rural livelihood. It not only improves the living standard of the rural people but also improves access to information, better health for women and children and an extension of indoor income generating activities. However, poor maintenance, lack of technical knowledge, and training hampered the operation and repairing functions of solar energy technology in the rural community. F or impr oving effective management of solar energy technologies, there is a need to incr ease end user awareness of system use, end-user capacity to troubleshoot problems, and level of service, quality and timeliness of repairs. The local government should come forward to incr ease awareness among beneficiaries and ensure the effective functioning of these systems.
Population dynamic and fisheries management of Eeuropen sea bass,Dicentrarchus labrax (f. Moronidae) from Bardawil lagoon, North Sinai, Egypt

opulation dynamic of European seabass, Dicentrarchus labrax was studied from a small scale fishery of Bardawil lagoon. 1688 specimens ranged between 18.2 and 64.7 cm TL and 62 to 2823 g total weight, were collected from August, 2009 to November, 2010. The relationship between length and weight was estimated as W = 0.014 L. Age was determined using scales’ reading technique for 586 individuals and the longevity of this species was found to be 6 years. Growth in length and weight at the end of each year was calculated. The growth parameters of the von Bertalanffy equation were calculated as L∞ = 70.82 cm, K = 0.35 yr and t0 = -0.217 yr. The observed and predicted extreme lengths were 64.5 and 70.05 cm, respectively. Total, natural and fishing mortality rates were 1.03 yr, 0.39 yr and 0.64 yr, respectively. The current exploitation rate (E = 0.6229) indicated that the stock of seabass in Bardawil lagoon is heavily exploited. The length at first capture Lc was estimated as 20.16 cm. The maximum allowable limit of exploitation (Emax) was 0.5, while that at maximum economic yield was 0.42. Based on these results, this important species may be in danger of severe declines in the near future where the stock was over-fished and small fish were unprotected by the current size regulation. Also, the results indicated that an increase of Lc would be associated with an increase in yields at the existing exploitation rate. Thus, for management purpose, the current exploitation rate must be reduced from 0.62 to 0.31 (50%) or the present length at first capture (Lc) should be increased from 20.16 to 32 cm at the current the exploitation rate.
The moderating effect of uncertainty avoidance on overall perceived value of the online purchasing process

The aim of this study is to analyse differences in the overall perceived value of a service purchased online, and the consequences for international consumer behaviour, taking consumers ́ uncertainty avoidance as a moderating variable. A questionnaire was administered to 300 international consumers who had purchased a service via the Internet. The results reveal that in the formation of overall perceived value – which embraces both the online purchase and also enjoyment of the service – moderating effects are generated by uncertainty avoidance. It explores how overall perceived value is formed when the entire purchasing process is taken into account, and the variations that occur in this process depending on whether it relates to Spanish or British consumers.
Influence of age on physical traits of Japanese quail (Coturnix coturnix japonica) eggs

La production de la caille (Coturnix coturnix japonica) prend de l'importance par suite des qualites de l'espece pour la production d'œufs. Il existe peu de publications sur les caracteristiques physiques qui pemnettent d'evaluer l'evolution de la qualite des œufs, au cours du cycle de ponte. Nous avons determine, sur 1 044 œufs de caille choisis en fonction de l'âge de la pondeuse (8, 12, 17, 21, 25, 30, 34 et 39 sem]: le poids de l'œuf, sa densite, ses longueur et largeur pour calculer son index de forme, la longueur et la hauteur de l'albumen et du jaune, l'epaisseur de la coquille, l'epaisseur de la membrane et finalement les unites de qualite interne (IQU) comme index le plus precis de la variabilite de qualite de l'œuf. Les resultats obtenus sont indiques aux tableaux 11, 111, IV. Le poids moyen de l'œuf est de 10,69 g et augmente avec l'âge. La longueur de l'œuf augmente de 30,54 a 32, 12 mm entre 8 et 30 sem d'âge pour diminuer ensuite. La hauteur du jaune et l'index de forme sont maximum a 39 sem d'âge. La densite est de 1,072 a 1,069 respectivement a 8 et 39 sem d'âge. l'epaisseur de la coquille s'accroit de 8 a 17 sem d'âge (0,194 a 0,201) pour diminuer ensuite. La hauteur de l'albumen et l'IQU sont plus eleves a 8 sem d'âge et diminuent ensuite. Deux variables, l'epaisseur de la coquille et l'IQU, caracterisent le mieux la qualite de l'œuf et sont les plus eleves a 17 et 8 sem d'âge respectivement. C'est en debut de ponte que la qualite de l'œuf de caille est la meilleure
Labor Market Performance and Farm Size-Productivity Relationship in rural India 1

In this paper, we use a three-round farm-level panel from rural India to explore the existence and evolution of the inverse relationship between farm size and productivity that has been found in a large empirical literature. While present throughout, the inverse relationship weakened significantly over time; the estimated elasticity of productivity with respect to farm size increased from 0.73 to 0.95 from 1982 to 2007. Key drivers are better functioning labor markets and a narrowing of efficiency differences between own and hired labor, possibly due to greater use of machinery. Structural transformation and a transition towards larger farms thus did not hurt productivity and economic efficiency. 1 Klaus Deininger is lead economist in the World Bank.
