Öffentliche Bibliotheken sind in der Digitalen Bildung von großer Bedeutung. Sie vermitteln digitale Kompetenzen, nutzen zunehmend neue Technologien und verleihen digitale Medien. Die Arbeit befasst sich mit der Förderung und Finanzierung digitaler Angebote in Bibliotheken. Zu Beginn wird ein Überblick über die Bibliotheksgesetzgebung in Deutschland gegeben. In diesem Zusammenhang wird die Forderung der Bibliotheken nach einer Normierung zur Pflichtaufgabe für Kommunen erörtert und ein Vergleich mit den europäischen Ländern Dänemark und Finnland gezogen. Eine Untersuchung der Drittmittelförderung auf Landesebene, Bundesebene und der Europäischen Kommission zeigt die Verortung der Bibliotheken in Förderprogrammen auf. Im Anschluss werden anhand von Best-Practice-Beispielen alternative Finanzierungsmöglichkeiten dargestellt. Meinungen von Vertretern aus Bibliotheken weisen auf die Vorteile und Nachteile von Drittmittelförderung, Fundraising, Rechtsformwechsel, Integration in die Stadtentwicklung oder die Entwicklung von Bibliothekskonzeptionen, Bibliotheksentwicklungsplänen sowie die Regelung durch Kulturfördergesetze hin. Ausgehend von den Ergebnissen der untersuchten Finanzierungmöglichkeiten wird abschließend die Notwendigkeit von Bibliotheksgesetzen diskutiert. Hieraus ergibt sich, dass Bibliotheksgesetze für eine einheitliche und zukunftsfähige Entwicklung der Bibliotheken in der Digitalen Bildung notwendig sind. Zugleich wird deutlich, dass die derzeit bestehenden Gesetze diese Anforderungen nicht leisten.

FID Civil Engineering, Architecture and Urbanism digital - A platform for science (BAUdigital)
(2022)
University Library Braunschweig (UB Braunschweig), University and State Library Darmstadt (ULB Darmstadt), TIB – Leibniz Information Centre for Technology and Natural Sciences and the Fraunhofer Information Centre for Planning and Building (Fraunhofer IRB) are jointly establishing a specialised information service (FID, "Fachinformationsdienst") for the disciplines of civil engineering, architecture and urbanism. The FID BAUdigital, which is funded by the German Research Foundation (DFG, "Deutsche Forschungsgemeinschaft"), will provide researchers working on digital design, planning and production methods in construction engineering with a joint information, networking and data exchange platform and support them with innovative services for documentation, archiving and publication in their data-based research.
Bereits zum dritten Mal in Folge nahm eine zehnköpfige Gruppe Studierender der Hochschule Hannover aus dem Vollzeit- sowie dem berufsbegleitenden Bachelor-Studiengang Informationsmanagement, in Begleitung zweier Dozentinnen, an der BOBCATSSS-Konferenz teil. Nachdem bisher ausschließlich auf der Hochschulwebseite und tagesaktuell im Blog über Erfahrungen und Erlebnisse während der drei BOBCATSSS-Exkursionen berichtet wurde, folgt hiermit nun ein zusammenhängender Beitrag über die diesjährige Konferenz vom 24. bis zum 26. Januar 2018 in Riga, Lettland. Die BOBCATSSS-Konferenz ist eine internationale Konferenz der Bibliotheks- und Informationswissenschaften. Im Gegensatz zu IFLA & Co wird sie fast ausschließlich von Studierenden wechselnder Universitäten in Europa ausgerichtet.
Background: Stereotactic radiosurgery (SRS) is an effective treatment for trigeminal neuralgia (TN). Nevertheless, a proportion of patients will experience recurrence and treatment-related sensory disturbances. In order to evaluate the predictors of efficacy and safety of image-guided non-isocentric radiosurgery, we analyzed the impact of trigeminal nerve volume and the nerve dose/volume relationship, together with relevant clinical characteristics.
Methods: Two-hundred and ninety-six procedures were performed on 262 patients at three centers. In 17 patients the TN was secondary to multiple sclerosis (MS). Trigeminal pain and sensory disturbances were classified according to the Barrow Neurological Institute (BNI) scale. Pain-free-intervals were investigated using Kaplan Meier analyses. Univariate and multivariate Cox regression analyses were performed to identify predictors.
Results: The median follow-up period was 38 months, median maximal dose 72.4 Gy, median target nerve volume 25mm3, and median prescription dose 60 Gy. Pain control rate (BNI I-III) at 6, 12, 24, 36, 48, and 60 months were 96.8, 90.9, 84.2, 81.4, 74.2, and 71.2%, respectively. Overall, 18% of patients developed sensory disturbances. Patients with volume ≥ 30mm3 were more likely to maintain pain relief (p = 0.031), and low integral dose (< 1.4 mJ) tended to be associated with more pain recurrence than intermediate (1.4–2.7 mJ) or high integral dose (> 2.7 mJ; low vs. intermediate: log-rank test, χ2 = 5.02, p = 0.019; low vs. high: log-rank test, χ2 = 6.026, p = 0.014). MS, integral dose, and mean dose were the factors associated with pain recurrence, while re-irradiation and MS were predictors for sensory disturbance in the multivariate analysis.
Conclusions: The dose to nerve volume ratio is predictive of pain recurrence in TN, and re-irradiation has a major impact on the development of sensory disturbances after non-isocentric SRS. Interestingly, the integral dose may differ significantly in treatments using apparently similar dose and volume constraints.
This paper presents a possibility to extend the formalism of linear indexed grammars. The extension is based on the use of tuples of pushdowns instead of one pushdown to store indices during a derivation. If a restriction on the accessibility of the pushdowns is used, it can be shown that the resulting formalisms give rise to a hierarchy of languages that is equivalent with a hierarchy defined by Weir. For this equivalence, that was already known for a slightly different formalism, this paper gives a new proof. Since all languages of Weir's hierarchy are known to be mildly context sensitive, the proposed extensions of LIGs become comparable with extensions of tree adjoining grammars and head grammars.
Background: Upsurge in cardiopulmonary dysfunctions in Enugu, Nigeria, involved mainly cement workers, automobile spray painters, woodworkers, and Cleaners and was worsened in the dry season, suggesting the need for an occupation-specific characterization of the disease features and seasonal evaluation of air quality for prevention and management.
Methods: We conducted a randomized cross-sectional study of eighty consenting participants (in Achara Layout, Enugu), comprising 20 cement workers (39.50 ± 14.95 years), 20 automobile spray painters (40.75 ± 9.85 years), 20 woodworkers (52.20 ± 9.77 years), and 20 cleaners (42.30 ± 9.06 years). The air quality, some haematological (fibrinogen-Fc, and C-reactive protein-CRP), and cardiopulmonary parameters were measured and analyzed using ANCOVA, at p < 0.05.
Results: The dry season particulate matter (PM) in ambient air exceeded the WHO standards in the New layout [PM10 = 541.17 ± 258.72 µg/m3; PM2.5 = 72.92 ± 25.81 µg/m3] and the University campus [PM10 = 244 ± 74.79 µg/m3; PM2.5 = 30.33 ± 16.10 µg/m3], but the former was twice higher. The PM differed significantly (p < 0.05) across the sites. Forced expiratory volume at the first second (FEV1) (F = 6.128; p = 0.001), and Peak expiratory flow rate (PEFR) (F = 5.523; p = 0.002), differed significantly across the groups. FEV1/FVC% was < 70% in cement workers (55.33%) and woodworkers (61.79%), unlike, automobile spray painters (72.22%) and cleaners (70.66%). FEV1 and work duration were significantly and negatively related in cement workers (r = -0.46; r2 = 0.2116; p = 0.041 one-tailed). CRP (normal range ≤ 3.0 mg/L) and Fc (normal range—1.5–3.0 g/L) varied in cement workers (3.32 ± 0.93 mg/L versus 3.01 ± 0.85 g/L), automobile spray painters (2.90 ± 1.19 mg/L versus 2.54 ± 0.99 mg/L), woodworkers (2.79 ± 1.10 mg/L versus 2.37 ± 0.92 g/L) and cleaners (3.06 ± 0.82 mg/L versus 2.54 ± 0.70 g/L).
Conclusion(s): Poor air quality was evident at the study sites, especially in the dry season. Cement workers and automobile spray painters showed significant risks of obstructive pulmonary diseases while woodworkers had restrictive lung diseases. Cement workers and cleaners recorded the highest risk of coronary heart disease (CRP ≥ 3.0 mg/L). The similarity in Fc and CRP trends suggests a role for the inflammation-sensitive proteins in the determination of cardiovascular risk in cement workers and cleaners. Therefore, there are occupation-specific disease endpoints of public health concern that likewise warrant specific preventive and management approaches among the workers.
Background: Foodstuff traders operating from warehouses (FTFW) are potentially exposed to dangerous rodenticides/pesticides that may have adverse effects on cardiopulmonary function. Methods: 50 consenting male foodstuff traders, comprising 15 traders (21–63 years) operating outside warehouses and 35 FTFW (20–64 years), were randomly recruited at Ogbete Market, Enugu, in a cross-sectional observational study of spirometric and electrocardiographic parameters. 17 FTFW (21–57 years) participated in focus group discussions. Qualitative and quantitative data were analysed thematically and with independent t-test and Pearson correlation coefficient at p < 0.05, respectively. Results: Most FTFW experienced respiratory symptoms, especially dry cough (97,1%) and wheezing (31.4%) with significant reductions in forced vital capacity (FVC) (t = -2.654; p = 0.011), forced expiratory volume in one second (FEV1) (t = -2.240; p = 0.030), maximum expiratory flow rate (FEF200-1200) (t = -1.148; p = -0.047), and forced end-expiratory flow (FEF25-75) (t = -1.11; p = 0.007). The maximum mid-expiratory flow (FEF25-75) was marginally decreased (p > 0.05) with a significantly prolonged (p < 0.05) QTc interval. Conclusion: Allergic response was evident in the FTFW. Significant decrease in FVC may negatively impact lung flow rates and explains the marginal decrease in FEF25-75, which implies a relative limitation in airflow of peripheral/distal airways and elastic recoil of the lungs. This is consistent with obstructive pulmonary disease; a significant decrease in FEF75-85/FEV1 supports this conclusion. Significant decrease in FEF200-1200 indicates abnormalities in the large airways/larynx just as significantly prolonged ventricular repolarization suggests cardiac arrhythmias.
Background: Autism Spectrum Disorder (ASD) is characterized by impairments in social communication, limited repetitive behaviors, impaired language development, and interest or activity patterns, which include a group complex neurodevelopmental syndrome with diverse phenotypes that reveal considerable etiological and clinical heterogeneity and are also considered one of the most heritable disorders (over 90%). Genetic, epigenetic, and environmental factors play a role in the development of ASD.
Aim: This study was designed to investigate the extent of DNA damage in parents of autistic children by treating peripheral blood mononuclear cells (PBMCs) with bleomycin and hydrogen peroxide (H2O2).
Methods: Peripheral blood mononuclear cells (PBMCs) were isolated by the Ficoll method and treated with a specific concentration of bleomycin and H2O2 for 30 min and 5 min, respectively. Then, the degree of DNA damage was analyzed by the alkaline comet assay or single cell gel electrophoresis (SCGE), an effective way to measure DNA fragmentation in eukaryotic cells.
Results: Our findings revealed that there is a significant difference in the increase of DNA damage in parents with affected children compared to the control group, which can indicate the inability of the DNA molecule repair system. Furthermore, our study showed a significant association between fathers’ occupational difficulties (exposed to the influence of environmental factors), as well as family marriage, and suffering from ASD in offspring.
Conclusion: Our results suggested that the influence of environmental factors on parents of autistic children may affect the development of autistic disorder in their offspring. Subsequently, based on our results, investigating the effect of environmental factors on the amount of DNA damage in parents with affected children requires more studies.
Background
Systematic reviews demonstrated that gait variables are the most reliable predictors of future falls, yet are rarely included in fall screening tools. Thus, most tools have higher specificity than sensitivity, hence may be misleading/detrimental to care. Therefore, this study aimed to determine the validity, and reliability of the velocity field diagram (VFD -a gait analytical tool), and the Timed-up-and-go test (TUG)-commonly used in Nigeria as fall screening tools, compared to a gold standard (known fallers) among community-dwelling older adults.
Method
This is a cross-sectional observational study of 500 older adults (280 fallers and 220 non-fallers), recruited by convenience sampling technique at community health fora on fall prevention. Participants completed a 7-m distance with the number of steps and time it took determined and used to compute the stride length, stride frequency, and velocity, which regression lines formed the VFD. TUG test was simultaneously conducted to discriminate fallers from non-fallers. The cut-off points for falls were: TUG times ≥ 13.5 s; VFD’s intersection point of the stride frequency, and velocity regression lines (E1) ≥ 3.5velots. The receiver operating characteristic (ROC) area under the curves (AUC) was used to explore the ability of the E1 ≥ 3.5velots to discriminate between fallers and non-fallers. The VFD’s and TUG’s sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were determined. Alpha was set at p < 0.05.
Results
The VFD versus TUG sensitivity, specificity, PPV and NPV were 71%, 27%, 55%, and 42%, versus 39%, 59%, 55%, and 43%, respectively. The ROC’s AUC were 0.74(95%CI:0.597,0.882, p = 0.001) for the VFD. The optimal categorizations for discrimination between fallers/non-fallers were ≥ 3.78 versus ≤ 3.78 for VFD (fallers versus non-fallers prevalence is 60.71% versus 95.45%, respectively), with a classification accuracy or prediction rate of 0.76 unlike TUG with AUC = 0.53 (95% CI:0.353,0.700, p = 0.762), and a classification accuracy of 0.68, and optimal characterization of ≥ 12.81 s versus ≤ 12.81 (fallers and non-fallers prevalence = 92.86% versus 36.36%, respectively).
Conclusion
The VFD demonstrated a fair discriminatory power and greater reliability in identifying fallers than the TUG, and therefore, could replace the TUG as a primary tool in screening those at risk of falls.
Schattenbibliotheken sind Lösungen, die sich aus einem Literaturmangel in der Forschung ergeben haben. Urheberrechtlich geschützte Inhalte werden hier online jedem frei zur Verfügung gestellt. In der vorliegenden Arbeit wird versucht, das Wirken dieser Dokumentsammlungen einzuordnen. So wird die Entstehung von Schattenbibliotheken aufgezeigt, auf den rechtlichen Umgang mit diesen Plattform eingegangen, zwei Schattenbibliotheken beispielhaft näher betrachtet und deren Auswirkungen abgebildet, bevor die Arbeit mit einem persönlichen Fazit abschließt.
Die fortschreitende Digitalisierung unserer modernen Welt betrifft zwangsläufig auch den Bereich der Nachlässe. Fast jede verstorbene Person hinterlässt nicht nur Hausrat, Bücher, Bargeld oder Wohnungen, sondern auch digitale Spuren in Form von Daten auf heimischen Computern sowie E-Mail Konten, Chatverläufe in Nachrichtensofortdiensten auf Smartphones, Online-Bankkonten, Konten bei Bezahldiensten, Internethandelsplattformen, sozialen Netzwerken, sowie Daten unterschiedlichster Art in Cloudspeicherorten oder in anderer nicht genannter Form im World-Wide-Web. Wahrscheinlich werden diese digitalen Speicherorte oder Zugangsdaten deshalb noch nicht grundsätzlich in Vorsorgevollmachten bzw. Testamenten benannt, weil sie noch nicht im nachlass-verwaltenden Bewusstsein der Bevölkerung verankert sind. Der nahezu selbstverständlich gewordene Umgang mit den digitalen Formaten sollte diese jedoch in die Auflistung des Nachlasses miteinschließen, damit eine Erbengemeinschaft die Möglichkeit erhält, sich auch um diesen Teil des Nachlasses adäquat kümmern zu können.
Die vorliegende Arbeit befasst sich mit der Erschließung historischer Bestände nach RDA. Inhaltlich begrenzt sie sich auf ausgewählte spezifische Merkmale alter Drucke und ihrer Formalerschließung mit RDA. Die Umstellung auf das neue Regelwerk, welches Anwen-dungsrichtlinien für alle Materialien vereinen soll, und einige in den Bibliotheksgremien diskutierte Aspekte wie z. B. „cataloger’s judgement“ haben die zentrale Frage dieser Arbeit veranlasst: Ist RDA für die Erschließung alter Drucke geeignet?
Die Arbeit untersucht spezifische Merkmale alter Drucke. Sie betrachtet die bestehende Erschließungspraxis alter Drucke und geht auf die Grundlagen und wesentliche Inhalte von RDA ein. Zu wissenschaftlichen Methoden der Arbeit gehören der Regelwerkevergleich und das Experteninterview. Die Gegenüberstellung von RDA und den RAK-WB lässt erkennen, dass RDA sich prinzipiell für die Erschließung alter Drucke eignet und Elemente der bibliographischen Beschreibung ähnlich wie die RAK-WB abbildet. Wegen des allgemeinen Charakters sind einige Richtlinien von RDA noch zu konkretisieren. Mehrwert gegenüber den RAK-WB versprechen die normierten Sucheinstiege, die Erfassung von Werken und Beziehungen. Das Interview mit Christoph Boveland, dem Experten auf dem Gebiet Katalogisierung Alter Drucke, bringt neue Erkenntnisse über geplante Empfehlungen zur Erschließung alter Drucke mit RDA, Erweiterung des Standardelemente-Set usw. Basierend auf den Ergebnissen der Gegenüberstellung und der Meinung von Christoph Boveland wird eine Aussage zur Entwicklung der Lehrveranstaltung „Formalerschließung historischer Bestände“ an der Hochschule Hannover getroffen.
