Partikule kao izazov - za prevodioce i izdavače (na primerlu srpskoslovenskog prevoda antilatinskih traktata Gregorija Palame i Varlaama Kalabrijskog)

Die Übersetzung der antilateinischen Traktate der byzantinischen Theologen Gregorios Palamas (1296-1359) und Barlaam von Kalabrien (1290-1348) Über den Ausgang des Heiligen Geistes entstand in den 60er Jahren des 14. Jahrhunderts. Die älteste Abschrift dieser Übersetzung, die Handschrift Dečani 88, ist zugleich die Arbeitshandschrift der Übersetzer. Sie enthält auf jeder Seite Korrekturen, die einen unmittelbaren Einblick in den Übersetzungsprozess bieten. Aus diesen Korrekturen ist ersichtlich, dass die Übersetzer bei der Wiedergabe nicht nur der theologischen Termini, sondern auch der Partikeln geschwankt haben. Der Autor verbindet diese Schwankungen mit dem Problem der Erhaltung der Argu-mentationsform der Traktate von Gregorios Palamas und Barlaam von Kalabrien in der Über-setzung und analysiert ein konkretes Beispiel: die altserbische Partikel daj.

Learning Software-Maintenance Tasks in the Transition Phase of Offshore Outsourcing Projects: Two Learning-Theoretical Perspectives

The increasing practice of offshore outsourcing software maintenance has posed the challenge of effectively transferring knowledge to individual software engineers of the vendor. In this theoretical paper, we discuss the implications of two learning theories, the model of work-based learning (MWBL) and cognitive load theory (CLT), for knowledge transfer during the transition phase. Taken together, the theories suggest that learning mechanisms need to be aligned with the type of knowledge (tacit versus explicit), task characteristics (complexity and recurrence), and the recipients’ expertise. The MWBL proposes that learning mechanisms need to include conceptual and practical activities based on the relative importance of explicit and tacit knowledge. CLT explains how effective portfolios of learning mechanisms change over time. While jobshadowing, completion tasks, and supportive information may prevail at the outset of transition, they may be replaced by the work on conventional tasks towards the end of transition.

Linked Services for Enabling Interoperability in the Sensing Enterprise

In future, the so called “sensing enterprise”, as part of the Future Internet, will play a crucial role in the success or the failure of an enterprise. We present our vision of an enterprise interacting with the physical world based on a retail scenario. One of the main challenges is the interoperability not only between the enterprise IT systems themselves, but also between these systems and the sensing devices. We will argue that semantically enriched service descriptions, the so called linked services will ease interoperability between two or more enterprises IT systems, and between enterprise systems and the physical environment.

Are cryptic host species also cryptic to parasites? Host specificity and geographical distribution of acanthocephalan parasites infecting freshwater Gammarus

Many parasites infect multiple host species. In coevolving host–parasite interactions, theory predicts that parasites should be adapted to locally common hosts, which could lead to regional shifts in host preferences. We studied the interaction between freshwater Gammarus (Crustacea, Amphipoda) and their acanthocephalan parasites using a large-scale field survey and experiments, combined with molecular identification of cryptic host and parasite species. Gammarus pulex is a common host for multiple species of Acanthocephala in Europe but, in Switzerland, is less common than two cryptic members of the Gammarus fossarum species complex (type A and type B). We found that natural populations of these cryptic species were frequently infected by Pomphorhynchus tereticollis and Polymorphus minutus. Four additional parasite species occurred only locally. Parasites were more common in G. fossarum type B than in type A. Infection experiments using several host and parasite sources confirmed consistently lower infection rates in G. pulex than in G. fossarum type A, suggesting a general difference in susceptibility between the two species. In conclusion, we could show that cryptic host species differ in their interactions with parasites, but that these differences were much less dramatic than differences between G. fossarum (type A) and G. pulex. Our data suggest that the acanthocephalans in Switzerland have adapted to the two most common Gammarus species in this region where host species frequencies differ from near-by regions in Europe.

Laparoscopic versus open end colostomy closure: a single-center experience

The aim of this study was to review our experience with laparoscopic end colostomy closure. A retrospective review of a prospectively entered database was performed. Proportions and continuous variables were compared using the Fisher's exact and the Mann-Whitney U tests, respectively. Within the study period, 53 patients underwent closure of end colostomies. The main reasons for the colonic resections were perforated diverticulitis (52.7%) and neoplasms (20.8%). In 28 patients (53%), laparoscopic closure (LC) was attempted. Demographics did not differ between the attempted LC and the primary open closure (OC) group. The conversion rate from an LC to an OC was 50 per cent (14 of 28), mostly as a result of adhesions (71.4%). Hospital length of stay (HLOS) was significantly longer for the OC than with the attempted LC group (15.4 ± 11.9 days vs 11.3 ± 8.5 days, P = 0.046). The overall complication rate was not different between the completed LC and the OC groups (43 vs 56%, P = 0.634). The majority of complications detected (91.1%) were minor and could be treated conservatively. The role of laparoscopy to close end colostomies is questionable, because the conversion rate is high. However, a shorter HLOS can be expected when laparoscopy is successful. To reduce morbidity resulting from prolonged operation times, it is crucial to convert early and pre-emptively if hostile adhesions are found.

How do objective and subjective career success interrelate over time?

The present research is concerned with the direction of influence between objective and subjective career success. We conducted a prospective longitudinal study with five waves of measurement that covered a time span of 10 years. Participants were professionals working in different occupational fields (N=1,336). We modelled the changes in objective success (income, hierarchical position), in other-referent subjective success (subjective success as compared to a reference group), and in self-referent subjective success (job satisfaction) by means of latent growth curve analysis. Objective success influenced both the initial level and the growth of other-referent subjective success, but it had no influence on job satisfaction. Most importantly, both measures of subjective success and both their initial levels and their changes had strong influences on the growth of objective success. We conclude that the ‘objective success influences subjective success’ relationship is smaller than might be expected, whereas the ‘subjective success influences objective success’ relationship is larger than might be expected.

Hepeviridae: An expanding family of vertebrate viruses

The hepatitis E virus (HEV) was first identified in 1990, although hepatitis E-like diseases in humans have been recorded for a long time dating back to the 18th century. The HEV genotypes 1–4 have been subsequently detected in human hepatitis E cases with different geographical distribution and different modes of transmission. Genotypes 3 and 4 have been identified in parallel in pigs, wild boars and other animal species and their zoonotic potential has been confirmed. Until 2010, these genotypes along with avian HEV strains infecting chicken were the only known representatives of the family Hepeviridae. Thereafter, additional HEV-related viruses have been detected in wild boars, distinct HEV-like viruses were identified in rats, rabbit, ferret, mink, fox, bats and moose, and a distantly related agent was described from closely related salmonid fish. This review summarizes the characteristics of the so far known HEV-like viruses, their phylogenetic relationship, host association and proposed involvement in diseases. Based on the reviewed knowledge, a suggestion for a new taxonomic grouping scheme of the viruses within the family Hepeviridae is presented.

Prevalence and Risk Factors for Therapy Escalation in Ulcerative Colitis in the Swiss IBD Cohort Study.

BACKGROUND Physicians traditionally treat ulcerative colitis (UC) using a step-up approach. Given the paucity of data, we aimed to assess the cumulative probability of UC-related need for step-up therapy and to identify escalation-associated risk factors. METHODS Patients with UC enrolled into the Swiss IBD Cohort Study were analyzed. The following steps from the bottom to the top of the therapeutic pyramid were examined: (1) 5-aminosalicylic acid and/or rectal corticosteroids, (2) systemic corticosteroids, (3) immunomodulators (IM) (azathioprine, 6-mercaptopurine, methotrexate), (4) TNF antagonists, (5) calcineurin inhibitors, and (6) colectomy. RESULTS Data on 996 patients with UC with a median disease duration of 9 years were examined. The point estimates of cumulative use of different treatments at years 1, 5, 10, and 20 after UC diagnosis were 91%, 96%, 96%, and 97%, respectively, for 5-ASA and/or rectal corticosteroids, 63%, 69%, 72%, and 79%, respectively, for systemic corticosteroids, 43%, 57%, 59%, and 64%, respectively, for IM, 15%, 28%, and 35% (up to year 10 only), respectively, for TNF antagonists, 5%, 9%, 11%, and 12%, respectively, for calcineurin inhibitors, 1%, 5%, 9%, and 18%, respectively, for colectomy. The presence of extraintestinal manifestations and extended disease location (at least left-sided colitis) were identified as risk factors for step-up in therapy with systemic corticosteroids, IM, TNF antagonists, calcineurin inhibitors, and surgery. Cigarette smoking at diagnosis was protective against surgery. CONCLUSIONS The presence of extraintestinal manifestations, left-sided colitis, and extensive colitis/pancolitis at the time of diagnosis were associated with use of systemic corticosteroids, IM, TNF antagonists, calcineurin inhibitors, and colectomy during the disease course.

Fas ligand and soluble Fas -opposing molecules in melanoma lung metastasis

Deregulation of apoptotic cell death can result in aberrant accumulation of cells and increased tumor incidence. Fas (CD95) and Fas ligand (FasL) are a receptor-ligand pair whose activation induces apoptosis in many cell types. Previously, we demonstrated that low metastatic, Fas+ K1735-P murine melanoma cells spontaneously metastasize to the lung following orthotopic injection into FasL-deficient (gld) mice compared to wild-type (wt) controls. We further demonstrated that the expression of the Fas antagonist soluble Fas (sFas) directly correlates with disease stage in patients with melanoma, breast, and colon cancer. These findings document a role for host-derived FasL, in the control of metastatic disease and suggest a role for tumor-associated sFas in acquiring metastatic potential. To directly test whether FasL expressed on lymphocytes or on lung stromal cells restricts metastasis, bone marrow chimeras were generated between C3H wt and C3H gld mice. Chimeric animals were injected subcutaneously with 5 × 105 K1735-P and the incidence and number of spontaneous lung metastases scored. The data show that wt mice receiving gld marrow had a greater number of lung metastases (median 9.5, range 2–31) than gld mice reconstituted with wt marrow (median 1, range 0–31; p < 0.016). Interestingly, both groups had fewer metastases compared to gld controls (median 18.5, range 0–46) but more than wt controls (median 2, range 0–7). These observations provide the first evidence that both hematopoietic- and nonhematopoietic-host derived FasL, are important in the control of melanoma metastasis to the lung. To directly test whether tumor-associated sFas expression can enhance metastasis, K1735-P cells were transfected with three isoforms of sFas (Exo4Del, Exo6Del, and Exo3, 4, 6Del). RT-PCR and ELISA analysis confirmed the expression of sFas RNA and protein respectively. Following intravenous injection of 5 × 104 cells, sFas transfected cells formed significantly more experimental lung metastases [Exo6Del clone 3 (median 22, range 0–36), Exo6Del clone 7 (median 31, range 4–50), Exo3, 4, 6Del (median 22.5, range 13–48)] compared to vector control cells (median 6.5, range 3–29). Together, these data provide the first evidence that sFas is sufficient to enhance the metastatic potential of Fas+ melanoma cells. ^
