While rare in new onset epilepsy, sudden unexpected death (SUDEP) is the leading cause of death among patients with chronic refractory epilepsy, accounting for 20-70 % of all deaths in such populations. In the absence of a clear understanding of the mechanisms behind SUDEP, a rational approach to its prevention could at best be based on identification of risk factors that might be amenable to intervention. Other papers that will be discussed are "Does Seizure Surgery Alter the Mortality of Epilepsy?" by E. Trinka and "What can We Learn From Hospital Based Studies?" by D. Shakleton.

One of the papers that will be discussed is "Remission: Insights From the Clinic," by M.J. Brodie. Remission of seizures is the major goal in treating epilepsy. It can be defined as a decrease or subsidence in the violence of a disease. Remission is, therefore, not a cure. Many definitions and remission rates are quoted in the literature since scholar William Gowers stated in 1881 that the spontaneous cessation of seizures is an event too rare to be anticipated in any given case. Other papers that will be discussed are "Refratoriness: Insights From the Clinic," by G. Bauer and "Role of Ion Channels in the Resistance to AEDs," by W. Wadman.

In the growing field of evolutionary psychiatry renewed emphasis is given to the fact that neuroethology and evolutionary biology in general can help to better understand psychiatric symptoms and pathogeneses. Fixed action patterns are a very important part of normal behavior and are very likely to underlie much of psychiatric symptomatology. Other papers that will be discussed are "Intracerebral Recording of Hyperkinetic and Emotional Seizures," by S. Francione and "Functional Anatomy of Paroxysmal Emotional Manifestations in Frontal Lobe Seizures," by P. Chauvel.

The article presents information about abstracts of various papers that will be discussed at the Discussion Group of the 6th European Congress on Epileptology that will be held on May 31, 2004. One of the papers that will be discussed is "Spatio-Temporal Dynamics of Interictal Networks in Mesial Temporal Lobe Epilepsy," by F. Bartolomei. Interictal spikes are dynamic events, which involve specific brain circuits in partial epilepsies. The relationship between interictal and ictal networks is complex and controversial. A better understanding of the human interictal networks is a crucial objective, since the study of interictal spikes is a major method for epilepsy localization. Other papers that will be discussed are "Localizing Value of Interictal Spikes in Partial Epilepsies," by C. Baumgartner and "Analysis of Interictal and Ictal Patterns in Partial Epilepsies," by G. Alarcon.

The article presents information about abstracts of various papers that will be discussed at the Discussion Group of the 6th European Congress on Epileptology that will be held on May 31, 2004. One of the papers that will be discussed is "Reflex Syncopes, Breath-Holding Spells, Faints and Anoxic-Epileptic Seizures," by J. Stephenson and A. Nechay. Some syncopes are easily miss-diagnosed as epilepsy. Diagnostic confusion is even more likely when syncopes induce true epileptic seizures, producing anoxic-epileptic seizures. Neurally mediated syncopes have many names that vary with the age of the patient, but share a common albeit poorly understood pathophysiology. Other papers that will be discussed are "Pseudoseizures," by I. Tuxhorn and "Epilepsy and Migraine," by G. Gobbi.

The Action Pack has been designed to enable people with epilepsy to improve their care and treatment. Other papers that will be discussed are "Measuring Stigma in the Real World," by M. Pfafflin and "Epidemiology of Newly Diagnosed Epilepsy," by A. Hauser.

This article focuses on the 1993 Joint Meeting with the American Economic Association which will be held in Anaheim, California during January 5-7, 1993. The program will consist primarily of contributed papers. Submitted abstracts should not be over 300 words in length, and should be submitted in triplicate. Each person may submit only one paper, or be a co-author on multiple submissions provided that if all such papers were accepted, no person would present more than one paper. Abstracts should represent original manuscripts not previously presented to the Econometric Society or submitted to other professional organizations for presentation at these same meetings.

The article discusses the first Latin American Meeting of the Econometric Society from July 14-16, 1980 in Buenos Aires, Argentina. Contributed papers' abstracts should not surpass 300 words and should be received before April 15, 1980. The abstracts should be labeled with name, institutional affiliation, address, and field to which the paper belongs. Finished versions of accepted papers should be sent to the Program Chairmen prior to May 31, 1980. A list of members of the Program Committee for the meeting is presented.

The method of selecting abstracts for an international congress at which only 15% of submitted papers could be accepted entailed a panel of 12 assessors using their specialised knowledges but presentation of the abstract was also important in selection. There was only a limited agreement between assessors in arranging abstracts in order of merit, so that a single assessor would be unacceptable.
Use of the full panel to grade all abstracts was very expensive, but it could be replaced, without unacceptable injustice, by dividing the work randomly among groups of three selectors. [ABSTRACT FROM AUTHOR]

In this paper, we describe the problem of recommending conference sessions to attendees and show how novel extensions to traditional model-based recommender systems, as suggested in Adomavicius and Tuzhilin [CHECK END OF SENTENCE], can address this problem. We introduce Recommendation Engine by CONjoint Decomposition of ITems and USers (RECONDITUS)—a technique that is an extension of preference-based recommender systems to recommend items from a new disjoint set to users from a new disjoint set. The assumption being that preferences exhibited by users with known usage behavior (e.g., past conference session attendance), which can be abstracted by projections of user and item matrices, will be similar to ones of new (different) users where the basic environment and item domain are the same (e.g., new conference). RECONDITUS requires no item ratings, but operates on observed user behavior such as past conference session attendance. The RECONDITUS paradigm consists of projections of both user and item data, and the learning of relationships in projected space. Once established, the relationships enable predicting new relationships and provide associated recommendations. The approach can encompass several traditional data mining problems where both clustering and prediction are necessary. RECONDITUS has been evaluated using data from the Oracle OpenWorld conference.
