10001 manuscripts in practice: Perl, XML, medieval chronicles, and why Unicode rocks‎

I work in the field of Armenian historiography. This means I get to play with medieval manuscripts. The things I'm doing with the manuscripts are theoretically interesting, but pretty boring in practice, so I'm using Perl to program away the most boring bits. I will talk about the problems of text criticism in general, what sorts of things can and can't be done by the computer, my initial aversion to XML, how I was shown (some of) the error of my ways, and how I'm combining a bunch of isolated pieces of technology that were mostly already in use to achieve fame and fortune in the world of Armenian studies.

Enabling the evolution of J2EE applications through reverse engineering and quality assurance

Enterprise Applications are complex software systems that manipulate much persistent data and interact with the user through a vast and complex user interface. In particular applications written for the Java 2 Platform, Enterprise Edition (J2EE) are composed using various technologies such as Enterprise Java Beans (EJB) or Java Server Pages (JSP) that in turn rely on languages other than Java, such as XML or SQL. In this heterogeneous context applying existing reverse engineering and quality assurance techniques developed for object-oriented systems is not enough. Because those techniques have been created to measure quality or provide information about one aspect of J2EE applications, they cannot properly measure the quality of the entire system. We intend to devise techniques and metrics to measure quality in J2EE applications considering all their aspects and to aid their evolution. Using software visualization we also intend to inspect to structure of J2EE applications and all other aspects that can be investigate through this technique. In order to do that we also need to create a unified meta-model including all elements composing a J2EE application.

Driving the refactoring of Java Enterprise applications by evaluating the distance between application elements

Java Enterprise Applications (JEAs) are complex systems composed using various technologies that in turn rely on languages other than Java, such as XML or SQL. Given the complexity of these applications, the need to reverse engineer them in order to support further development becomes critical. In this paper we show how it is possible to split a system into layers and how is possible to interpret the distance between application elements in order to support the refactoring of JEAs. The purpose of this paper is to explore ways to provide suggestions about the refactoring operations to perform on the code by evaluating the distance between layers and elements belonging those layers. We split JEAs into layers by considering the kinds and the purposes of the elements composing the application. We measure distance between elements by using the notion of the shortest path in a graph. Also we present how to enrich the interpretation of the distance value with enterprise pattern detection in order to refine the suggestion about modifications to perform on the code.

Dementia presenting with visual complaints

A 78-year-old female developed memory problems after a 2-year history of persistent visual complaints. Ocular pathology did not explain the extent of her perceived visual impairment. Cognitive screening tests found prominent visuo-constructive deficits and a comprehensive dementia assessment revealed the diagnosis of Alzheimer's disease. This case describes visual complaints as the initial symptom of dementia, pre-dating memory impairment by several years. We discuss clinical signs of cerebral visual impairment and suggest a simple screening measure.

Immigrant Incorporation in Western Europe

Immigrant incorporation (or integration) is a subfield of migration studies, and it constitutes a genuinely interdisciplinary undertaking of sociologists, political scientists, anthropologists, lawyers, and historians. In none of these disciplines, however, has it carved out an established niche for itself. In contrast to the United States, where the study of immigrant integration (or “assimilation” as US researchers prefer to say) is more firmly grounded in sociology than in political science, a characteristic of the European scene is a larger prominence of political scientists, macro comparativists, and legal-institutional scholars. This reflects the fact that immigrant integration in Europe is, to a much larger degree than in the United States, framed by public policies, and it often goes along with major transformations of state institutions (most importantly citizenship) and national identities. European states (even France) are ethnic nation-states, where sedentariness and not moving is the norm, and they stand for countries that are much less attuned to, and constituted by, international migration than the classic immigrant nations of North America and Oceania. Overall, European scholarship is marked, on one side, by single-country studies by national experts, which are often solicited by their respective governments interested in policy advice (but increasingly also supported by supranational research bodies). On the other side, most agenda-setting work has grown out of qualitative single-person studies (often dissertations) by macro sociologists and political comparativists not (or only incidentally) rooted in national university systems and disconnected from policy contexts. The field is in need of further conceptual development and of theoretically reflected, genuinely comparative work of the second type, which is mostly off the public funding radar.

Drug-related emergency department visits by elderly patients presenting with non-specific complaints

BACKGROUND Since drug-related emergency department (ED) visits are common among older adults, the objectives of our study were to identify the frequency of drug-related problems (DRPs) among patients presenting to the ED with non-specific complaints (NSC), such as generalized weakness and to evaluate responsible drug classes. METHODS Delayed type cross-sectional diagnostic study with a prospective 30 day follow-up in the ED of the University Hospital Basel, Switzerland. From May 2007 until April 2009, all non-trauma patients presenting to the ED with an Emergency Severity Index (ESI) of 2 or 3 were screened and included, if they presented with non-specific complaints. After having obtained complete 30-day follow-up, two outcome assessors reviewed all available information, judged whether the initial presentation was a DRP and compared their judgment with the initial ED diagnosis. Acute morbidity ("serious condition") was allocated to individual cases according to predefined criteria. RESULTS The study population consisted of 633 patients with NSC. Median age was 81 years (IQR 72/87), and the mean Charlson comorbidity index was 2.5 (IQR 1/4). DRPs were identified in 77 of the 633 cases (12.2%). At the initial assessment, only 40% of the DRPs were correctly identified. 64 of the 77 identified DRPs (83%) fulfilled the criteria "serious condition". Polypharmacy and certain drug classes (thiazides, antidepressants, benzodiazepines, anticonvulsants) were associated with DRPs. CONCLUSION Elderly patients with non-specific complaints need to be screened systematically for drug-related problems. TRIAL REGISTRATION ClinicalTrials.gov: NCT00920491.
