The treatment options for infra-renal arteriosclerotic occlusive (ASO) vascular disease have never been more varied. The history of open revascularization procedures now exceeds 60 years. This represents three generations of vascular surgeons, the most recent of whom have witnessed more than 30 years of endovascular surgery development and dissemination. Both open and endovascular treatments should be considered mature; moreover, we are improving our understanding of the strategies and tactics that lead to the clinical application of one approach instead of the other. There are other important factors in the choice of a treatment modality to be used for a specific patient. Prime among these is evolving patterns of occlusive disease and the increasing severity of arterial calcification.

Abstract The book under review serves as a significant contribution to the field of Trans-Himalayan linguistics. Designed as a vade mecum for readers with little linguistic background in these three languages, Nathan W. Hill’s work attempts, on the one hand, a systematic exploration of the shared history of Burmese, Tibetan and Chinese, and, on the other, a general introduction to the reader interested in obtaining an overall understanding of the state of the art of the historical phonology of these three languages. Whilst it is acknowledged that the book in question has the potential to be a solid contribution to the field, it is also felt that few minor issues can be also addressed.

Can it be justified to use neuroscientific technologies for influencing the functioning of human brain as a means of preventing offenders from engaging in future criminal conduct? This is indeed a highly controversial question and one which has a dark prehistory. Moreover, it is also a question that has attracted recent optimistic attention from researchers across different scientific fields. The purpose of this book is to consider various ethical challenges surrounding this question. More precisely, the author discusses issues such as, Is it morally acceptable to offer more lenient sentences to offenders in return for participation in neuroscientific treatment programmes? Would such offers be unacceptably coercive? Can it ever be morally justified to use compulsory neurointerventions as a means of preventing crime? Is it possible to administer neurointerventions as a type of punishment? Would it be acceptable for physicians to participate in the administration of neurointerventions on offenders? What is the moral significance of the sordid history of brain interventions for the present or future use of such treatment options? The author argues, on the one hand, that many of the in-principle objections to neuroscientific treatment are premature but also, on the other, that—given the way criminal justice systems currently function—we are well-advised not to put such treatment methods into practice.

The rapid evolution and informational growth of blogs requires enhanced functionality for searching, navigating and linking content. This paper presents the French Blog Annotation Corpus \textsc{FLOG}, intended to provide a research testbed for the study of annotation practices, and specifically tagging and categorizing blog posts. The corpus covers a ten year time span of blog posts on cooking, law, video games and technology. Statistical analysis of the corpus suggests that tag annotation of posts is more frequent than category attribution, but on the other hand categories provide a richer semantic structure for post classification and search. The review of the state of the art on automatic tag suggestion shows that tag suggestion tools are not of widespread use yet between bloggers, which might be a consequence of methods that do not take into account the past tagging history of the blog, the context of the post within the blog and the tagging pattern of each blog author.

Abstract CASE DESCRIPTION 6-month-old and 7-month-old spayed female domestic shorthair cats were referred because of complications associated with inadvertent bilateral ureteral ligation and transection during ovariohysterectomy. CLINICAL FINDINGS Both cats had a 1- to 2-day history of lethargy, inappetence, and vomiting. Initial exam findings included lethargy, signs of abdominal pain, anuria, and dehydration. Clinicopathologic testing revealed azotemia and hyperkalemia. Abdominal ultrasonography revealed peritoneal effusion and bilateral pyelectasia in both cats and retroperitoneal effusion in one. Fluid analysis in both cats supported a diagnosis of uroabdomen. TREATMENT AND OUTCOME Exploratory celiotomy was performed in both cats, and bilateral ureteral ligation and transection was confirmed. Bilateral renal descensus and ureteroneocystostomy with an intravesicular mucosal apposition technique was successfully performed in both cats. Clinicopathologic evaluation performed 1 day after surgery in one cat and 5 days after surgery in the other revealed complete resolution of azotemia. Ultrasonographic examination of the urogenital tract performed approximately 4 months after surgery in the first cat and 1 month after surgery in the second cat revealed complete resolution of renal pelvic dilation bilaterally. CLINICAL RELEVANCE Bilateral intravesicular ureteroneocystostomy in conjunction with bilateral renal descensus was used successfully to treat bilateral ureteral transection that occurred in 2 cats during routine ovariohysterectomy. Limited treatment options currently exist for this serious complication, and euthanasia is often considered. This technique, which relies on the use of the natural surrounding tissues for successful treatment, can offer a potential treatment option to correct this uncommon but devastating complication.

In his somewhat controversial book Remnants of Auschwitz, Agamben makes brief reference to Theodor Adorno’s apparently contradictory remarks on perceptions of death post-Auschwitz, positions that Adorno had taken concerning Nazi genocidal actions that had seemed also to reflect something horribly errant in the history of thought itself. There was within such murderous acts, he had claimed, a particular degradation of death itself, a perpetration of our humanity bound in some way to affect our perception of reason itself. The contradictions regarding Auschwitz that Agamben senses to be latent within Adorno’s remarks involve the intuition ‘on the one hand, of having realized the unconditional triumph of death against life; on the other, of having degraded and debased death. Neither of these charges – perhaps like every charge, which is always a genuinely legal gesture – succeed in exhausting Auschwitz’s offense, in defining its case in point’ (RA 81). And this is the stance that Agamben wishes to hammer home quite emphatically vis-à-vis Adorno’s limitations, ones that, I would only add, seem to linger within Agamben’s own formulations in ways that he has still not come to reckon with entirely: ‘This oscillation’, he affirms, ‘betrays reason’s incapacity to identify the specific crime of Auschwitz with certainty’ (RA 81).

In several late texts, Derrida meditated on Paul Celan's poem ‘Grosse, Glühende Wölbung’, in which the departure of the world is announced. Delving into the ‘origin’ and ‘history’ of the ‘conception’ of the world, this paper suggests that, for Derrida, the end of the world is determined by and from death—the death of the other. The death of the other marks, each and every time, the absolute end of the world.

Adalbert Wraný (*1836, †1902) was a doctor of medicine, with his primary specialization in pediatric pathology, and was also one of the founders of microscopic and chemical diagnostics. He was interested in natural sciences, chemistry, botany, paleontology and above all mineralogy. He wrote two books, one on the development of mineralogical research in Bohemia (1896), and the other on the history of industrial chemistry in Bohemia (1902). Wraný also assembled several natural science collections. During his lifetime, he gave to the National Museum large collections of rocks, a collection of cut precious stones and his library. He donated a collection of fossils to the Geological Institute of the Czech University (now Charles University). He was an inspector of the mineralogical collection of the National Museum. After his death, he bequeathed to the National Museum his collection of minerals and the rest of the gemstone collection. He donated paintings to the Prague City Museum, and other property to the Klar Institute of the Blind in Prague. The National Museum’s collection currently contains 4 325 samples of minerals, as well as 21 meteorites and several hundred cut precious stones from Wraný’s collection.

Emmanuel Lévinas, the philosopher of ethics par excellence in the twentieth century, and by own merit one of the most important ethical philosophers in the history of western philosophy, is also the philosopher of the Other. Thereby, it can be said that no thought has deepened like his in the ups and downs of the ethical relationship between subject and otherness. The general objective of this work is to expose in a simple and understandable way some ideas that tend to be quite dark in the philosophical work of the author, since his profuse religious production will not be analyzed here. It is expected to show that his ideas about the being and the Other are relevant to better understand interpersonal relationships in times of 4.0 (re)evolution. As specific objectives, this work aims to expose in chronological order the main works of the thinker, with special emphasis on his ethical implications: Of the evasion (1935), The time and the Other (1947), From the existence to the existent (1947), Totality and infinity: An essay on exteriority (1961) and, last, Otherwise than being, or beyond essence (1974). In the judgment of Lévinas, history of western philosophy starting with Greece, has shown an unusual concern for the Being, this is, it has basically been an ontology and, accordingly, it has relegated ethics to a second or third plane. On the other hand and in a clear going against the tide movement, our author supports that ethics should be considered the first philosophy and more, even previous to the proper philosophize. This novel approach implies, as it is supposed, that the essential question of the philosophy slows down its origin around the Being in order to inquire about the Other: it is a philosophy in first person. Such a radical change of perspective generates an underlying change in how we conceive interpersonal relationships, the complex framework of meanings around the relationship Me and You, which also philosopher Martin Buber had already spoken of. As Lévinas postulates that ethics is the first philosophy, this involves that the Other claims all our attention, intellectual and emotional, to the point of considering that the relationship with the Other is one of the measures of our identity. Thus, “natural” attitude –husserlian word not used by Lévinas- would be to be in permanent disposition regarding to the meeting with the Other, to be in permanent opening state to let ourselves be questioned by him. Ontology, as the author says, being worried about the Being, has been likewise concerned about the Existence, when the matter is to concern about the particular Existent that every otherness supposes for us. In conclusion it can be affirmed that levinasian ethics of the meeting with the Other, particular Face, irreducible to the assumption, can contribute with an innovative looking to (re)evolving the interpersonal relationships in a 4.0 context.

In integrated water management, the issues are often complex by nature, they are capable of subjective interpretation, are difficult to express in standards and exhibit many uncertainties. For such issues, an equilibrium approach is not appropriate. A non-equilibrium approach has to be applied. This implies that the processes to which the integrated issue pertains, are regarded as “alive”’. Instead of applying a control system as the model for tackling the issue, a network is used as the model. In this network, several “agents”’ are involved in the modification, revision and rearrangement of structures. It is therefore an on-going renewal process (perpetual novelty). In the planning process for the development of a groundwater policy for the municipality of Amsterdam, a non-equilibrium approach was adopted. In order to do justice to the integrated character of groundwater management, an approach was taken, containing the following features: (1) working from global to detailed, (2) taking account of the history of the system, (3) giving attention to communication, (4) building flexibility into the establishing of standards, and (5) combining reason and emotions. A middle course was sought, between static, rigid but reliable on the one hand; dynamic, flexible but vague on the other hand.
