Zur Konzeption und Implementierung einer Infrastruktur für freie bibliographische Daten

The increasing awareness of the topic "Open Data" in the library world opens up important questions concerning the handling of open data. This article discusses the conceptual base lines of a technical Open Data infrastructure and work out the complex requirements such an infrastructure must meet. The covered aspects range from data publication and description to the versioning of open data. For some aspects promising points of contact are identified, e.g. in form of version control tools in the Open Source community or in form of running projects by the W3C or the Open Knowledge Foundation

‚Linked Data‘ - und warum wir uns im hbz-Verbund damit beschäftigen

The topic “Linked Open Data“ is pushing more and more into the library sphere. While “Open Data“ is all about the legal status of any kind of data, “Linked Data“ aims at augmenting the interoperability of data by consistently applying (web-)standards. This article begins with an illustration of why “Linked Data“ is relevant to the library world. This is followed by a short introduction to the most important Linked Data standards and some thoughts on how to migrate bibliographic data to these standards. Finally the current activities of the hbz library network concerning this matter are presented

Effect of sainfoin (Onobrychis viciifolia) silage and hay against gastrointestinal nematodes in lambs

The objective of the study was to examine the effect of dried and ensiled sainfoin (Onobrychis viciifolia) against two species of gastrointestinal nematodes (Haemonchus contortus, Cooperia curticei) in lambs. Twenty-four days post experimental infection, 24 lambs were allocated to 4 equal groups. Group A and B received sainfoin silage and control silage respectively for 16 days. Groups C and D were fed on sainfoin hay or control hay for the same period. Feeds were administered ad libitum and mean refusals and live weight were regularly recorded. Individual faecal egg counts (FEC) were performed twice weekly. After the feeding period all lambs were slaughtered for post mortem investigation. The consumption of sainfoin hay was associated with a significant reduction of the adult H. contortus burden by 47 % (P < 0.05) whereas no significant difference was seen when feeding sainfoin silage (49 %, P = 0.112). The C. curticei worm burden was not significantly reduced by either sainfoin hay or silage. At slaughter FEC were significantly reduced by sainfoin hay by 64 % (P < 0.001) compared to the control feed. After feeding sainfoin silage FEC decreased by 48 % (P = 0.056). There was a tendency of better live weight gain in sainfoin hay fed animals compared to the control fed ones (P=0.07). These results demonstrate a nematocidal effect of a tanniferous forage legume against gastrointestinal nema¬¬todes, which was more pronounced against H. contortus. The antiparasitic effects were largely preserved when feeding sainfoin silage, suggesting this conservation procedure to be a valuable alternative to hay

Individual administration of three tanniferous forage plants to lambs artificially infected with Haemonchus contortus and Cooperia curticei

We investigated direct anthelmintic effects associated with the feeding of fresh tanniferous forages against established populations of Haemonchus contortus and Cooperia curticei in lambs. Twenty-four parasite naive lambs were inoculated with a single dose of infective larvae of these two parasites 27 days prior to the start of the feeding experiment. Lambs were individually fed with either chicory (Cichorium intybus), birdsfoot trefoil (Lotus corniculatus), sainfoin (Onobrychis viciifolia) or a ryegrass/ lucerne mixture (control) for 17 days. Animals where then united to one flock and subjected to control feeding for another 11 days to test the sustainability of potentially lowered egg excretion generated by tanniferous forage feeding. When compared to the control, administration of all tanniferous forages was associated with significant reductions of total daily faecal egg output specific to H. contortus (chicory: 89%; birdsfoot trefoil: 63%; sainfoin: 63%; all tests P < 0.05) and a tendency of reduced H. contortus worm burden (chicory: 15%; birdsfoot trefoil: 49% and sainfoin: 35% reduction). Irrespective of the condensed tannin (CT) containing fodder, no anthelmintic effects were found against C. curticei. Cessation of CT-feeding followed by non-CT control feeding did not result in a re-emergence of faecal egg counts based on faecal dry matter (FECDM) in any group, suggesting that egg output reductions are sustainable. The moderate to high concentrations of CTs in birdsfoot trefoil (15.2 g CTs kg-1 dry matter (DM)) and sainfoin (26.1 g CTs kg-1 DM) were compatible with the hypothesis that the antiparasitic effect of these forages is caused by their content of CTs. For chicory (3 g CTs kg-1 DM), however, other secondary metabolites need to be considered. Overall, birdsfoot trefoil and in particular sainfoin seem promising candidates in contributing to an integrated control strategy against H. contortus not only by mitigating parasite related health disturbances of the host but also by a sustained reduction of pasture contamination. # 2007 Elsevier B.V.

Analisis Pengaruh Kualitas Layanan Terhadap Tingkat Kepuasan Pengguna Aplikasi Sobat IndiHome Menggunakan Metode System Usability Scale (SUS)

Aplikasi Sobat IndiHome merupakan layanan produk IndiHome dengan sistem baru yang dimiliki oleh telkomsel. Aplikasi Sobat Indihome menerima respon keluhan dari pengguna terhadap ketidakpuasan pada proses pemasangan yang masih sangat lama, termasuk untuk menangani pengecekan jaringan IndiHome. Penelitian ini bertujuan untuk mengevaluasi dan mengukur tingkat usability kepuasan pengguna terhadap kualitas Aplikasi Sobat IndiHome dengan metode System Usability Scale (SUS). Hasil pengukuran dari metode SUS pada penelitian ini berfokus pada acceptability, grade scale, dan adjective rating. Dalam menentukan hasil skor SUS maka hasil dari kuesioner yang telah diisi oleh 30 responden direkapitulasi. Dalam perhitungan SUS digunakan lima skala Likert. Responden diminta untuk memberikan 10 pernyataan SUS yang sesuai dengan pengukuran subjektifnya. Kuesioner SUS ini dapat digunakan untuk mengukur tingkat kepuasan pengguna pada suatu produk. Setiap item pernyataan memiliki skor kontribusi yang berkisar dari antara 0 hingga 4. Hasil akhir pengukuran tingkat usability kepuasan pengguna berada pada skor range 51-71 dengan hasil grade scale 68 dan pada tingkat penerimaan pengguna termasuk dalam kategori kelas D dengan arti Marginal sehingga pada aplikasi Sobat IndiHome ini masih dapat diterima. Versi Adjective Rating dengan Skor SUS sebesar 68 termasuk kedalam kategori Ok, bahwa aplikasi Sobat IndiHome ini dapat diterima oleh penggunanya namun masih perlu dilakukan perbaikan. Peneliti menyarankan pengembang Aplikasi Sobat IndiHome dapat melakukan kajian ulang mengenai aspek-aspek yang membuat rendahnya tingkat kepuasan pada Aplikasi Sobat IndiHome baik dari segi fitur dan segi Informasi
