The new definition of UT1 adopted by the IAU is useful but for many reasons not quite satisfactory. It depends e. g., 1) on the approximate values of some astronomical constants, and is therefore subject to revision in the future. 2) Since it is used for the FK5-based astronomical reference system, its eventual usefulness for space techniques is questioned. 3) Although the new and old UT1 merge continuously at a chosen epoch, they do not form a homogeneous series of data, in other words, the old and the new UT1 are systematically different from each other. 4) Neither the new definition, nor the way to convert the old to the new one is based on simple concepts and these are thus likely to be misunderstood by the nonspecialist user. A conceptual definition of UT1 is suggested, in order to correct this situation and a formula to realize this conceptual definition is presented, which can be used unchanged for every technique and is easily understood by the nonspecialist community.

Abstract: Very little research has been devoted to the way in which the textual genetics approaches the manuscripts in the text processing. However the future of the genetics depends, partly, on the interest which one can carry to this new materiality of the manuscript. The notion of text, the concept of what text is, have they been changed, or at least modified by the use of text processing? To write a text is to elaborate a discourse in the form of an utterance and to record it. The order of the discourse, in other words, the semiotic (the linguistic recognizable) / semantic (the meaning expressed (uttered) in the discourse) ratio should in no way be modified by the use of text processing. What changes, on the other hand, it is the materialization of the paper support of the text and consequently the status of this materialization.

Crowdsourcing is a new technology and a new business model that will change the way in which we work in many fields in the future. Employers divide and source out their work to a huge number of anonymous workers on the Internet. The division and outsourcing is not a trivial process but requires the definition of complete new workflows – from the definition of subtasks, to the execution and quality control. A popular crowdsourcing project in the field of collection of geodata is OpenStreetMap, which is based on the work of unpaid volunteers. Crowdsourcing projects that are based on the work of unpaid volunteers need an active community, whose members are convinced about the importance of the project and who have fun to collaborate. This can only be realized for some tasks. In the field of geodata collection many other tasks exist, which can in principle be solved with crowdsourcing, but where it is difficult to find a sufficient large number of volunteers. Other incentives must be provided in these cases, which can be monetary payments.

We had better plan for the future, and in participation with others. It just might come. We need humility and not arrogance in these endeavors, determination and not abrogation, firmness without preconceived notions, self-confidence without too much self-interest, self-advocacy in the sense that we speak for our silent, other selves—our children. Even as we reflect in this bicentennial year on our illustrious past—and try to look into the future through our somewhat opalescent crystal balls—the present tends to overwhelm us. By the very nature and definition of our efforts, the practicing physician lives in the instant present—to the benefit of our patients, perhaps, but sometimes to the detriment of our own and our families' interests. Despite our deepest concerns and the nagging awareness of man's capability for his own destruction, we must take time to use the past's lessons and the present's problems to try to integrate a functional future. I speak for practical idealism. Even as independence was the rallying cry of Colonial times, so was interdependence the modus operandi within the Colonies themselves—constricted though it was by what we would now call "poor communications." Now our "poor communication" is autogenic rather than ecogenic!—the way we cope with the means they did not have. Try to think of pediatrics without the telephone! If we think things are not going to change, let us ponder a bit on what has happened in pediatrics in the last 200 years, the last 100 years, the last 40 years, the last 10 years.

Thirty years ago, in a paper on continued fractions, Stieltjes published a definition of the integral which bears his name. His replacement of the variable of integration x by a more general “base function” φ(x)—a change which throws so much light upon other theories of integration—received at first little attention, but has later sprung into greater prominence; so much so that Professor Hildebrandt, in summarizing these various theories in a paper to the American Mathematical Society, makes the statement that “it [the Stieltjes Integral] seems destined to play the central rôle in the integrational and summational processes of the future.” Yet even now the integral and the allied theory of differentiation with respect to a function have been subjected to little detailed analysis, and the possibilities of extension have been only touched upon. It is the object of this present paper to establish certain results which are of some value in themselves and which prepare the way for an attack upon the integral.

“The technologists are asking the church and its thinkers to help them define the goals of their effort, and to co-determine guidelines for the application of their newly found power. They are asking for a definition of what is human so that moral suasion will reinforce technological reason in giving order to what is now a dangerously open field of experimentation. The revolutionaries are asking that their hope be subsidized at a moment when it threatens to go bankrupt. They want a confidence that, in fact, the way of transformation, of liberation in the foundations of our systems, is the direction of our future.”

ResumenPara definir un objeto por lo general partiríamos refiriéndonos a aquello que podemos hacer con ese objeto, es decir la utilidad que obtenemos de él. Sin embargo ¿Cómo podemos definir un objeto que no es uno, sino muchos? ¿Cómo describir su forma si posee muchas formas? Y sobre todo cómo hablar de su función si teniendo muchas, es una sola la que lohace ser ese objeto. El souvenir es un objeto que nos plantea estas interrogantes debido a su ambigüedad, por lo que la idea de autenticidad resulta también una categoría compleja de analizar en ellos. En las primeras páginas plantearemos una definición conceptual de los objetos de recuerdo, desde su condición de objetos simbólicos, para intentar organizar a partir de su análisis una categorización acerca de la idea de autenticidad y cómo ésta se relativiza en el proceso de mediatización que implica el diseño de los recuerdos de viaje.AbstractTo defi ne an object usually would leave referring to what we can do with that object, ie the utility we derive from it. But how can we defi ne an object that is not one but many?How to describe the way if you have many ways? And especially how to talk about their role if taking many, it is one which makes him the object. The souvenir is an object that raises these questions because of its ambiguity, it is that the idea of authenticity is also a complex category of analysis in these objects. In the fi rst pages we will raise a conceptual defi nition of memorabilia, from its status as symbolic objects, to try to organize from a categorization analysis about the idea of authenticity.

The concept of microgaming in education is relatively new and it has evident potential for supporting learning in various learning environments. However, there is little consensus in the education literature on how micro-games are defined. The present article proposes a conceptual definition of mi-crogames by considering related terms and learning approaches in education. Microgames in education context are defined as very small and short games that provide brief engagement and meaningful experience for players, support learning and instruction toward specific objectives, and integrate with existing resources. This article further elaborates the key definition elements to indicate microgame characteristics and provides some examples to demonstrate the kinds of games that fit this definition. The proposed definition acts as a fundamental starting point to study microgames for educational purposes in the future.

AbstractIn this paper, the theory of necessity proposed by Robert Grosseteste is presented. After showing the wide range of various kinds of determination discussed by him (connected with: (1) one’s knowledge about the future, (2) predestination, (3) fate, (4) grace, (5) sin and temptation), a different context of Grosseteste’s use of the notion of necessity is analyzed (within logical and metaphysical approaches). At the heart of his theory lie: the definition of necessity, which is that something lacks the capacity (posse) for its opposite, and the distinction between two perspectives within which we can consider necessity: (1) the one according to which the truthfulness of a dictum determines that it cannot be the opposite, (2) a pre- or atemporal one, as if something had not yet begun. On these grounds, Robert explains that God’s omniscience is compatible with contingency, including human free decisions. Robert’s theory is still relevant and useful in contemporary debates, as it can provide strong arguments and enrich discussions, thanks to the twoperspectives approach, which generates nine kinds of positions on the spectrum of determinism and indeterminism.
