Ustanak u Rakovici 1871. u rumunjskom tisku Transilvanije i Mađarske
This study proposes a comparative analysis of the circulation of information between two peripheries of the Habsburg Monarchy (Croatia and Transylvania), respectively between a periphery and a center (Croatia and Pest), following the way in which the uprising in Rakovica in October 1871, together with its background and political connotations, were received, interpreted, and further transmitted to the Romanian-speaking public in Transylvania and Hungary by the Romanian press of the time. The objective of the study is to highlight the differences between the central and provincial press of an important ethnic group in Dualist Hungary, as well as to trace how a series of violent, unexpected, and potentially politically destabilizing events within one ethnic group were received and contextualized by the political elite of another ethnic group.U članku se donosi komparativna analiza informacija koje su kružile između dviju periferija Habsburške Monarhije (Hrvatske i Transilvanije), odnosno između periferije i središta (Hrvatske i Pešte). Autor prati način na koji je tadašnji rumunjski tisak primio i protumačio ustanak u Rakovici u listopadu 1871., uključujući njegovu pozadinu i političke konotacije, te prenio te informacije rumunjskoj javnosti u Transilvaniji i Mađarskoj. Cilj istraživanja bio je istaknuti razlike između središnjeg i pokrajinskog tiska namijenjenog toj važnoj etničkoj skupini u Ugarskoj za vrijeme dualizma, kao i ispitati kako je niz nasilnih, neočekivanih i potencijalno politički destabilizirajućih događaja unutar jedne etničke skupine primila i kontekstualizirala politička elita druge etničke skupine
Utemeljenje austrijske Vojne krajine u Transilvaniji i njeni kratkoročni te srednjoročni utjecaji
Establishing the Austrian military border in Transylvania was not only a military, but also a political, economic and, up to a point, religious decision, taken by the Crown near the end of a long and costly war, under specific circumstances and events taking place in the province. It was also probably the main reason why Empress Maria Theresa was remembered by several generations of Transylvanians, and remains one of the most celebrated acts of her reign according to Romanian historical writing. This paper seeks to provide a synthetic overview of the topic, based on both the international (mainly German and Austrian) and the Romanian historical literature, given the highly limited accessibility of the latter in terms of language and range of dissemination. It opens with short introductory historiographical considerations, followed by a presentation of the prerequisites and reasons for the border regiments’ creation, alongside the main steps in the establishment process. The second part provides a short analysis of the mutual benefits brought about by the military border for both the empire and the locals, as well as the difficulties and resistance encountered during the establishment, along with the short- and medium-term social implications.Utemeljenje transilvanijskih vojnokrajiških pukovnija nije bila samo vojna već i politička, ekonomska te do određene mjere i vjerska odluka koju je Bečki dvor donio potkraj dugog i skupog Sedmogodišnjeg rata (1756. – 1763.) i to pod specifičnim uvjetima i događajima koji su se događali u Transilvaniji. Ovo utemljenje vojnog sustava i pukovnija je vrlo vjerojatno glavni razlog zašto je carica Marija Terezija upamćena od strane nekoliko generacija stanovnika Transilvanije, a također ova caričina odluka pripada prema rumunjskoj historiografiji među najpoznatije i najhvaljenije poteze njezine vladavine. Sintetski pregled navedene teme u radu se temelji na relevantnim radovima rumunjske historiografije koju autor obilato upotpunjuje, obzirom na ograničenost šireg korištenja iste od strane povjesničara poradi jezika i slabe diseminacije, najrelevantnijim radovima međunarodne (uglavnom njemačke i austrijske) historiografije. U radu se nakon kratkog uvoda i osvrta na spomenute relevantne historiografske radove, prikazuje kronološkim slijedom razvoj preduvjeta i razloga za stvaranje transilvanijskih krajiških pukovnija s osvrtom na glavne korake tog procesa. Drugi dio rada donosi kratku analizu obostranih koristi i beneficija koje su, kako za Habsburšku Monarhiju i Bečki dvor tako i za lokalno stanovništvo Transilvanije, proizašle iz uspostave vojnokrajiških pukovnija. Dodatno, donosi se i prikaz poteškoća te otpora s kojima su se vlasti susretale prilikom utemeljenja navedenih pukovnija zajedno s osvrtom na kratkoročne i srednjoročne implikacije uspostave ove vojne organizacije na društvo
ŽUPNE MATIČNE KNJIGE IZ TRANSILVANIJE – IZVORI ZA POVIJEST MEDICINE (OD KASNOG 18. DO RANOG 20. STOLJEĆA)
This paper aims to analyse the typology of medical-historical information provided by parish registers from Transylvania – a category of primary sources used mainly by historical demographers.
The approach is descriptive and prospective in character: it creates a typology of the medical information to be found in the sources, while highlighting possible research directions and approaching a series of methodological and interpretation issues.
The parish registers contain references to medical actors (the midwife, the physician, the death inspector), to medical activities (vaccination), and to events regarding the history of medicine (multiple births, infant mortality, death-causing diseases and accidents, epidemics, etc.). Despite the fact that they provide mainly demographic data, some epidemiological and medicine-related information can prove interesting for researchers in the field of the historyof medicine. Such information is suitable for serial analyses and in some cases even for collective biography studies of the medical staff (e.g., the birth assistants and midwives), thus cross-referencing in many respects with cultural and social history. However, probably for reasons related to the sources’ accessibility, medical historians have not seemed very interested in these data, a situation which will hopefully change in the near future due to the newly compiled historical population databases.
The conclusions reached in this paper point towards the variety of medical-historical information contained in parish registers, highlighting the need for reconsidering them as sources not only for historical demography, but also for medical history.Ovaj rad ima za cilj analizirati tipologiju medicinsko-povijesnih informacija koje nude župne matice iz Transilvanije – kategoriju primarnih izvora koje koristi uglavnom povijesni demografi.
Pristup je po naravi deskriptivan i prospektivan: on stvara tipologiju medicinskih informacija koje se mogu naći u izvorima, pritom naglašavajući moguće istraživačke pravce i pristupajući nizu metodoloških i interpretacijskih problema.
Župne matice sadrže reference o medicinskim akterima (primalja, liječnik, inspektor smrti), medicinskim djelatnostima (cijepljenje) te događajima vezanih za povijest medicine (višestruka rođenja, smrtnost dojenčadi, smrtonosne bolesti i nesreće, epidemije, itd.).
Unatoč činjenici da one pružaju uglavnom demografske podatke, neke epidemiološke i za medicinu vezane informacije se dokazuju kao zanimljive za znanstvenike iz područja povijesti medicine. Takve informacije pogodne su za serijske analize, a u nekim slučajevima čak i za istraživanja kolektivne biografije medicinskog osoblja (npr. asistenata pri porodu i primalja), presijecajući se tako u mnogočemu s kulturnom i društvenom poviješću. Međutim, a vjerojatno zbog razloga koji se odnose na pristupačnost izvora, čini se da medicinski povjesničari nisu bili jako zainteresirani za ove podatke. Nadamo se da će se takva situacija promijeniti u bliskoj budućnosti zbog svježe prikupljenih povijesnih baza podataka stanovništva.
Zaključak do kojega se dolazi u ovom radu upućuje prema različitim medicinskopovijesnim informacijama koje su sadržane u župnim matičnim knjigama, naglašavajući potrebu za njihovo preispitivanje kao izvora ne samo za povijesnu demografiju, već i za medicinsku povijest
Rgtsp: a generalized top scoring pairs package for class prediction
Summary: A top scoring pair (TSP) classifier consists of a pair of variables whose relative ordering can be used for accurately predicting the class label of a sample. This classification rule has the advantage of being easily interpretable and more robust against technical variations in data, as those due to different microarray platforms. Here we describe a parallel implementation of this classifier which significantly reduces the training time, and a number of extensions, including a multi-class approach, which has the potential of improving the classification performance. Availability and Implementation: Full C++ source code and R package Rgtsp are freely available from http://lausanne.isb-sib.ch/~vpopovic/research/. The implementation relies on existing OpenMP libraries. Contact: [email protected]
An Explorative Analysis of ABCG2/TOP-1 mRNA Expression as a Biomarker Test for FOLFIRI Treatment in Stage III Colon Cancer Patients: Results from Retrospective Analyses of the PETACC-3 Trial
Biomarker-guided treatment for patients with colon cancer is needed. We tested ABCG2 and topoisomerase 1 (TOP1) mRNA expression as predictive biomarkers for irinotecan benefit in the PETACC-3 patient cohort. The present study included 580 patients with mRNA expression data from Stage III colon cancer samples from the PETACC-3 study, which randomized the patients to Fluorouracil/leucovorin (5FUL) +/- irinotecan. The primary end-points were recurrence free survival (RFS) and overall survival (OS). Patients were divided into one group with high ABCG2 expression (above median) and low TOP-1 expression (below 75 percentile) ("resistant") (n = 216) and another group including all other combinations of these two genes ("sensitive") (n = 364). The rationale for the cut-offs were based on the distribution of expression levels in the PETACC-3 Stage II set of patients, where ABCG2 was unimodal and TOP1 was bimodal with a high expression level mode in the top quarter of the patients. Cox proportional hazards regression was used to estimate the hazard ratios and the association between variables and end-points and log-rank tests to assess the statistical significance of differences in survival between groups. Kaplan-Meier estimates of the survival functions were used for visualization and estimation of survival rates at specific time points. Significant differences were found for both RFS (Hazard ratio (HR): 0.63 (0.44-0.92); p = 0.016) and OS (HR: 0.60 (0.39-0.93); p = 0.02) between the two biomarker groups when the patients received FOLFIRI (5FUL+irinotecan). Considering only the Microsatellite Stable (MSS) and Microsatellite Instability-Low (MSI-L) patients (n = 470), the differences were even more pronounced. In contrast, no significant differences were observed between the groups when patients received 5FUL alone. This study shows that the combination of ABCG2 and TOP1 gene expression significantly divided the Stage III colon cancer patients into two groups regarding benefit from adjuvant treatment with FOLFIRI but not 5FUL
Joint analysis of histopathology image features and gene expression in breast cancer
BACKGROUND
Genomics and proteomics are nowadays the dominant techniques for novel biomarker discovery. However, histopathology images contain a wealth of information related to the tumor histology, morphology and tumor-host interactions that is not accessible through these techniques. Thus, integrating the histopathology images in the biomarker discovery workflow could potentially lead to the identification of new image-based biomarkers and the refinement or even replacement of the existing genomic and proteomic signatures. However, extracting meaningful and robust image features to be mined jointly with genomic (and clinical, etc.) data represents a real challenge due to the complexity of the images.
RESULTS
We developed a framework for integrating the histopathology images in the biomarker discovery workflow based on the bag-of-features approach - a method that has the advantage of being assumption-free and data-driven. The images were reduced to a set of salient patterns and additional measurements of their spatial distribution, with the resulting features being directly used in a standard biomarker discovery application. We demonstrated this framework in a search for prognostic biomarkers in breast cancer which resulted in the identification of several prognostic image features and a promising multimodal (imaging and genomic) prognostic signature. The source code for the image analysis procedures is freely available.
CONCLUSIONS
The framework proposed allows for a joint analysis of images and gene expression data. Its application to a set of breast cancer cases resulted in image-based and combined (image and genomic) prognostic scores for relapse-free survival
On Performance Evaluation of Face Detection and Localization Algorithms
When comparing different methods for face detection or localization, one realizes that just simply comparing the reported results is misleading as, even if the results are reported on the same dataset, different authors have different views of what a correct detection/localization means. This paper addresses exactly this problem, proposing an objective measure for the goodness of a detection/localization for the case of frontal faces. The usage of the proposed technique insures a fair and unbiased way of reporting the results, making the experiment repeatable, measurable, and comparable by anybody else
