At CRIGEN, the GDF SUEZ research center for gas and new energies, a project on risk management on gas infrastructures (MARTHO project) is aimed, among other goals, at protecting the pipelines against external aggressions such as vibrations. Over the past few years, extensive construction of wind turbines has taken place all around the world in areas where many steel pipelines are already buried. The possible fall of these heavy machines may induce damageable vibrations to the pipeline. The common threshold used by the industry, established by the American Gas Association, is stated at PPV ≤ 50 mm.s−1. A more accurate and less conservative model of vibration propagation has been developed and validated by extensive field measurements coupled with a nonlinear 2D-finite element model for the soil. An experimental soil characterization through MASW tests coupled with vibration measurements was performed in a representative soil. As a result, safety distances between wind turbines and pipelines were considerably shortened compared to the previous model. The updated model is now part of the RAMCES software which has been developed for more than a decade at CRIGEN and is widely used in France by transmission operators.

The Common

The common sense of modern times was not always “common” in the past. For example, if it is true that inflation is caused by an oversupply of money, a short supply of money must cause deflation. However logical that sounds, though, it has not been so uncommon in history that rising prices were recognized as being caused by a scarcity of currency. Even in the same period, a common idea prevailing in one historical area was not always common in another; rather, it sometimes appeared in quite the opposite direction. It is likely that the idea that a government gains from bad currencies, while traders appreciate good ones, is popular throughout the world. In the case of China, however, its dynasties sometimes intentionally issued high-quality coins without regard to their losses. East Asia shared the idea that cheap currency harms the state, while an expensive currency harms the people. This is in considerable contrast with a common image in other regions that authorities gained profits from seigniorage.

Real World Problems

The past decade has witnessed incredible advances in building highly realistic and richly detailed simulated worlds. We readily endorse the common-sense assumption that people will be better equipped for solving real-world problems if they are trained in near-life, even if virtual, scenarios. The past decade has also witnessed a significant increase in our knowledge of how the human body as both sensor and as effector relates to cognition. Evidence shows that our mental representations of the world are constrained by the bodily states present in our moment-to-moment interactions with the world. The current study investigated whether there are differences in how people enact actions in the simulated as opposed to the real world. The current study developed simple parallel task environments and asked participants to perform actions embedded in a stream of continuous events (e.g., cutting a cucumber). The results showed that participants performed actions at a faster speed and came closer to incurring injury to the fingers in the avatar enacting action environment than in the human enacting action environment.

In a magazine devoted especially to the propagation of Geological knowledge, it seems no infringement of its space, no deterioration of its value, tha t some pains should be taken to aid the student in his early efforts, and to disperse broadcast some useful elementary information, which may prove to the mass at once a source of instruction and of enjoyment, and so, by clearing the road to future and higher studies, may foster a dawning taste, and ultimately prove the means of adding many volunteers, and not unlikely even some brilliant master-minds to the ranks of Geologists, that otherwise, deterred at the outset, might perhaps have turned their attention and talents to some more accessible, if not more congenial study.Who does not feel some interest in the past history of this beautiful world—the scene of our labours and of our loves—of our successes and of our failures—the stage of our existence and the tomb of our dust ? If the animated creations of the past were dumb brute animals, still the earth was green and gay with trees, and plants and flowers—the hu m of insects vibrated on the summer's air, and the snows of winter covered the ancient lands with their hyemal mantle—the tides of ocean rose and fell, and the world went rolling on through time and space, through years and seasons. There were earthquakes the n and blazing volcanos—and winds and storms—great waves and merry dancing ripples on the sea.

A glimpse of the ancient Indianans and the flourishing of India in ancient times give a glimpse of the whole of flourishing. Puranas are indicative of this irrefutable truth that India was the world famous and reached the peak of metaphysical, athletic and spiritual progress in ancient times. It is believed that the original source of knowledge and religion is Vedas. The glory of the Vedas is immense, but their vocabulary is unbearable and the process of rendering is quite complicated. But the Puranas alone make heart-felt to all the common sense in their simplest terms and with the help of plot style. Therefore, in all places, the Vedas have been agreed to understand through history, mythology. From the word of history, Mahabharata and Valmiki are also known as Ramayana and Yoga Vashastrai Granth. From these mythologies, the scholars of the past have composed many beautiful essays and arrangements, who is also a director of special purposive karma.

The United States is among the most religiously diverse countries in the world. Although such diversity is not a new phenomenon, its degree and visibility have increased dramatically in the past fifty years, reigniting the debate over a fundamental civic question: What is the common identity that binds us together? How we respond to religious diversity in the context of education has enormous implications for our democratic society. To the extent that previous frameworks such as exclusion or assimilation ever were desirable or effective, they no longer are. Increased religious diversity is an established fact and growing trend. The United States needs a more inclusive and robust civic framework for religious diversity in the twenty-first century—pluralism—and this framework should be an essential component of civic education.

Existentialism is a concern about the foundation of meaning, morals, and purpose. Existentialisms arise when some foundation for these elements of being is under assault. In the past, first-wave existentialism concerned the increasingly apparent inability of religion and religious tradition to provide such a foundation, as typified in the writings of Kierkegaard, Dostoevsky, and Nietzsche. Second-wave existentialism, personified philosophically by Sartre, Camus, and de Beauvoir, developed in response to the inability of an overly optimistic Enlightenment vision of reason and the common good to provide such a foundation. There is a third-wave existentialism, a new existentialism, developing in response to advances in the neurosciences that threaten the last vestiges of an immaterial soul or self. With the increasing explanatory and therapeutic power of neuroscience, the mind no longer stands apart from the world to serve as a foundation of meaning. This produces foundational anxiety. This collection of new essays explores the anxiety caused by this third-wave existentialism and some responses to it. It brings together some of the world’s leading philosophers, neuroscientists, cognitive scientists, and legal scholars to tackle our neuroexistentialist predicament and explore what the mind sciences can tell us about morality, love, emotion, autonomy, consciousness, selfhood, free will, moral responsibility, law, the nature of criminal punishment, meaning in life, and purpose.

Birth Time

A Man would see but little of the reality of the world if he shut himself up in his house, and only gazed out from the same window; he would learn little more if he contented himself with alternately gazing upon the scenes passing around him, from the windows of every storey. So a geologist, in limiting himself to the study of the rock-masses of a circumscribed area, would never, by the utmost perseverance, in going continually over the same ground, attain to a perfect understanding of the subject of his study. He must go abroad, either in his own person or equivalently, by making himself acquainted with the travels and labours of others. Our knowledge of the ancient conditions and relations of the oldest rock-masses would not be complete if we limited our investigations to those isolated patches in our own country, which, however important, are still only a part of that great whole, more important traces of which are to be met in regions far away. Thus those very old—indeed, primitive sedimentary rocks, represented in the British Isles in a fragmentary manner, as by the younger or bedded gneiss of the Scottish Highlands, assume in Canada and the Arctic regions proportions of great extent, and consequently, of far greater value. Far back in the obscurity of the past, as must be placed the birth-time of these primitive land-masses, we seem, in our first investigations, plunged in interminable ignorance, like the explorers of some vast subterranean cave in impenetrable darkness.

AbstractExpanding on the works of Beck and others on the growing business of risk, this article examines the role of the private security industry in the creation, management and perpetuation of the world risk society. It observes that the replacement of the concept of security with risk over the past decades has permitted private firms to identify a growing range of unknown and unknown-unknown dangers which cannot be eliminated, but require permanent risk management. Using the discourse of risk and its strategies of commercialised, individualised and reactive risk management, the private risk industry thus has contributed to the rise of a world risk society in which the demand for security can never be satisfied and guarantees continuous profits.

This paper discusses three games that are characterized by what I call “epistolary architecture,” showing how the games use their spatial distribution of communicative acts to subvert the common videogame trope of the unseen woman. In his essay “Game Design as Narrative Architecture,” Henry Jenkins outlines how some games distribute narrative progression across space rather than time, so that arrival at a particular location will trigger an event in the game’s story. Gone Home (2013) and Dear Esther (2012) use similar techniques, but to markedly different effect, by distributing subjective accounts of the past (external to the timeframe of the gameplay) around the game space by way of letters, recordings, and other messages. Bientôt L’été (2013) inverts this scenario. In it, a player walks along a seashore, receiving linguistic fragments brought in by the waves, then later rearticulates these into fractured conversations with another player in a remote location. Each of these games, in its own way, problematizes the trope of the unseen woman, which I argue has been a structuring principle in videogames for decades. In general, the unseen woman has been a destination, the endpoint of a quest and thus fundamentally outside the world of the gameplay. The epistolary architecture of Gone Home, Dear Esther, and Beintôt L’été is fundamental to the games’ ability to subvert this principle. Conversely, each game uses the figure of the unseen woman to complicate the player’s relationship to its story and its setting.

In spite of the sea change over the past sixty-odd years in the way we shop, from a personal interaction with the local shopkeeper to a cashierless self-checkout, and the billions of transactions that take place daily in stores and supermarkets around the world, there is a dearth of legal precedent regarding the legal mechanics of these transactions. This is particularly so as far as determining the very important practical issue of at what point the sale is perfecta (irrevocably concluded) is concerned. For example, a consumer receives a catalogue from a well-known store in which a flat screen television is advertized on special for R599. Well knowing that such television sets are normally sold for over R6000 the consumer rushes off to purchase a set only to be faced with a large sign which reads as follows: “Unfortunately the advertised price was incorrect, the correct price is R5 999. We apologise for the inconvenience.”A slightly different scenario is where the consumer is only informed of this mistake after she has removed the television set from the shelf and taken it to the cashier who proceeds to ring up the price of R5 999. When the consumer points out that this is not the advertised price the cashier informs her that a mistake was made and that in fact R5 999 is the correct price. Is there a point in time when the supplier, despite a mistake, may be bound by the advertised price? (The purpose of this article is to consider the point in time when the contract is regarded as perfecta. The scenario set out above may also constitute bait-advertising. This is an issue which we intend to consider in our next article.) It is against this backdrop that we attempt to provide some guidance to those who are obliged to comply with the provisions of the Consumer Protection Act, relating to displayed prices.In doing so, we shall consider the extent to which the Roman-Dutch-based common law has been influenced by English Law in this area of consumer protection. Reference will be made to the principles of the common law regarding the formation of a contract (particularly the point at which the contract comes into effect), quasi consent and mistake as well as relevant foreign precedent. We shall then deal with the changes brought about by the CPA.
