Barriers to Digital Preservation in Special Collections Departments
Authors: Fisher Katherine 
Published: February 2017

Abstract:This essay selectively surveys recent findings on digital preservation in special collections settings and examines the challenges that prevent widespread implementation. Using the University of Hawai‘i at Mānoa’s library to illustrate the situation facing many institutions, I discuss three types of barriers to digital preservation: workflow and procedural obstacles, resource limitations, and lack of buy-in.
Interferometrischer Liniensensor zur Formmessung von rotationssymmetrischen optisch glatten Oberflächen
Authors: Laubach Sören , Ehret Gerd , Lehmann Peter , Riebeling Jörg 
Published: February 2017

Zusammenfassung
Es wird ein neuartiges Formmesssystem basierend auf einem
interferometrischen Liniensensor vorgestellt. Der Liniensensor wird
mit einem Bewegungssystem so nachgeführt, dass die
Beleuchtungsstrahlen möglichst senkrecht zur Prüflingsoberfläche
stehen. Das linienbasierte Formmesssystem bietet die Möglichkeit einer
schnellen und flexiblen Messung. In den Überlappbereichen sind
redundante Informationen enthalten, die zu einer genaueren Auswertung
führen als bei einem Punktsensor. Die Formmessung mit Punktsensoren
ist langsam, und die Genauigkeit ist durch das Bewegungssystem
limitiert, da die Bewegungsachsen systematische und zufällige
Führungsfehler haben. Diese Führungsfehler können nicht ohne Weiteres
eliminiert werden und führen deshalb zu einer erhöhten
Messunsicherheit bei der Formmessung. Bei vollflächig messenden
Systemen werden i. Allg. sehr große Optiken benötigt, die mit hohen
Kosten verbunden sind. In diesem Beitrag wird der Aufbau des
linienbasierten Systems und exemplarisch einige Messergebnisse
vorgestellt.
Ortsaufgelöste optische Bestimmung von Materialanteilen in Mischungen
Authors: Krippner Wolfgang , Bauer Sebastian , Puente León Fernando 
Published: February 2017

Zusammenfassung
Aus aufgezeichneten Hyperspektralbildern lassen sich mittels sogenannter spektraler Entmischung die Anteile von Materialien in Materialmischungen bestimmen. Allerdings erfordert die Aufzeichnung solcher Bilder einen hohen Hardwareaufwand. Außerdem benötigt die spektrale Entmischung aufgrund des hohen Datenvolumens zeitintensive Berechnungen. Der vorgestellte Ansatz verlagert die Berechnung in angepasste Spektralfilter, sodass die Hyperspektralbilder bei einem zukünftigen modifizierten Hardwareaufbau gar nicht erst aufgezeichnet werden müssen und die gewünschten Materialanteile in Form von zweidimensionalen Grauwertbildern direkt erfasst werden.
Prozessuales Erklären
Authors: Aljets Enno , Hoebel Thomas 
Published: February 2017

Zusammenfassung:
Der Artikel zielt darauf ab, Grundzüge einer Methodologie prozessualen Erklärens (MpE) zu erörtern, die erstens gegenstandsoffen ist, sich zweitens in Bezug auf sozialtheoretische Prämissen möglichst wenig einschränkt und drittens generalisierende Aussagen erlaubt, die vom jeweils untersuchten Gegenstand abstrahieren. Der Begriff des Timings fungiert als explanatorisches Schlüsselkonzept. Die Erklärung setzt voraus, das interessierende Geschehen zunächst möglichst detailliert zu rekonstruieren. Während die basale Rekonstruktion dazu dient, die Sequenzialität der Ereignisse zu beschreiben, hat die komplexe Rekonstruktion zum Ziel, Verschachtelungen und Interferenzen der Sequenzen zu eruieren, die zusammengenommen das erklärungsbedürftige Phänomen bilden. Maßgeblich inspiriert ist die MpE durch zwei sehr unterschiedliche Untersuchungsfälle: (a) Massenerschießungen und (b) Empirische Bildungsforschung. Die Studien haben jedoch gemeinsam, dass die Verlaufsform des Wendepunkts zur prozessualen Erklärung der Ereignisse dient. Die Forschungsperspektive ist, weitere Verlaufsformen sozialen Geschehens in den hier vorgeschlagenen Ansatz einzubeziehen.
Crystal structures of [SbF6]− salts of di- and tetrahydrated Ag +, tetrahydrated Pd2 + and hexahydrated Cd2 + cations
Authors: Mazej Zoran , Goreshnik Evgeny 
Published: February 2017

Abstract
The [Ag(H2O)2]SbF6, is triclinic, P1̅ (No. 2), with a=6.6419(3) Å, b=7.6327(3) Å, c=11.1338(3) Å, α=95.492(3)°, β=96.994(3)°, γ=113.535(4)°, V=507.13(4) Å3 at 150 K, and Z=3. There are two crystallographically non-equivalent Ag+ cations. The Ag1 is coordinated by two water molecules with Ag–OH2 distances equal to 2.271(2) Å forming in that way a discrete linear [Ag(H2O)2]+ cation. Additionaly, it forms two short Ag···F contacts (2.630(2) Å), resulting in AgO2F2 plaquette, and four long ones (2×3.001(2) Å and 2×3.095(2) Å) with fluorine atoms located below and above the AgO2F2 plaquette. The H2O molecules bridge Ag2 atoms into {–[Ag(μ-OH2)2]–}n infinite chains, with Ag–O distances of 2.367(2)–2.466(2) Å. The [Pd(H2O)4](SbF6)2·4H2O is monoclinic, P2

/a (No.14), with a=8.172(2) Å, b=13.202(3) Å, c=8.188(3) Å, β=115.10(1)o, V=799.9(4) Å3 at 200 K, and Z=2. Its crystal structure can be described as an alternation of layers of [Pd(H2O)4]2+ cations (interconnected by H2O molecules) and [SbF6]− anions. It represents the first example where [Pd(H2O)4]2+ has been structurally determined in the solid state. Four oxygen atoms provided by H2O molecules are in almost ideal square-planar arrangement with Pd–O bond lengths 2×2.004(5) Å and 2×2.022(6) Å. The [Cd(H2O)6](SbF6)2, is orthorhombic, Pnnm (No.58), with a=5.5331(2) Å, b=14.5206(4) Å, c=8.9051(3) Å, V=715.47(4) Å3 at 200 K, and Z=2. It consists of [Cd(H2O)6]2+ cations and [SbF6]− anions.
On the Heisenberg Supermagnet Model in (2+1)-Dimensions
Authors: Yan Zhao-Wen 
Published: February 2017

AbstractThe Heisenberg supermagnet model is an important supersymmetric integrable system in (1+1)-dimensions. We construct two types of the (2+1)-dimensional integrable Heisenberg supermagnet models with the quadratic constraints and investigate the integrability of the systems. In terms of the gage transformation, we derive their gage equivalent counterparts. Furthermore, we also construct new solutions of the supersymmetric integrable systems by means of the Bäcklund transformations.

This Clinical Report was retired January 2024.
With the expansion of the adolescent immunization schedule during the past decade, immunization rates notably vary by vaccine and by state. Addressing barriers to improving adolescent vaccination rates is a priority. Every visit can be viewed as an opportunity to update and complete an adolescent’s immunizations. It is essential to continue to focus and refine the appropriate techniques in approaching the adolescent patient and parent in the office setting. Health care providers must continuously strive to educate their patients and develop skills that can help parents and adolescents overcome vaccine hesitancy. Research on strategies to achieve higher vaccination rates is ongoing, and it is important to increase the knowledge and implementation of these strategies. This clinical report focuses on increasing adherence to the universally recommended vaccines in the annual adolescent immunization schedule of the American Academy of Pediatrics, the American Academy of Family Physicians, the Centers for Disease Control and Prevention, and the American Congress of Obstetricians and Gynecologists. This will be accomplished by (1) examining strategies that heighten confidence in immunizations and address patient and parental concerns to promote adolescent immunization and (2) exploring how best to approach the adolescent and family to improve immunization rates.

Abstract: Contaminated hands can play pivotal role in the development and spread of healthcare-associated infections. Consequently hand hygiene practice performed with adequate technique and with adequate timing is an essential implement for patient safety. Inhibition of the practice of high level hand hygiene by the misconceptions or deficient knowledge of healthcare workers may lead to negative influence on the quality of patient care. Erroneous beliefs or “rumourous knowledge” acquired from colleagues can not only influence the attitude of healthcare workers, but can also give rise to insufficient hand hygiene compliance. Finding, interpreting and imparting the related evidence by delivering continuing education and lectures, highlighting the theoretical and practical know-how on hand hygiene could help to understand and imprint the evidence-based practice and adequate technique in the essential issue of hand hygiene.

Published: February 2017

Fekunditas dan diameter telur ikan merupakan bagian dari studi reproduksi biologi perikanan. Aspek ini dikaji dari tiga jenis ikan terbang, yaitu Cheilopogon cyanopterus, Hirundichthys oxycephalus, dan Parexocoetus mento yang dikumpulkan dari hasil tangkapan nelayan dengan jaring insang hanyut di perairan Takalar (Selat Makassar) dan Pemuteran (Bali Utara). Jumlah contoh yang diamati 58 gonad ikan betina yang berada pada tingkat kematangan gonad III dan IV. Fekunditas tertinggidimiliki oleh Parexocoetus mento, namun rata-rata fekunditas tertinggi dimiliki oleh jenis Hirundichthys oxycephalus. Korelasi antara fekunditas dan panjang total ikan memiliki tingkat keeratan yang rendah, sedangkan korelasi antara fekunditas dan bobot gonad memiliki tingkat keeratan yang kuat. Distribusidiameter telur ikan pada ketiga jenis ikan terbang ini tidak menunjukan perbedaan yang signifikan, namun secara umum diameter telur pada tingkat kematangan gonad III (0,33-2,21 mm) lebih kecil dari pada tingkat kematangan gonad IV (0,45-2,36 mm). Penelitian ini memberikan indikasi bahwaterdapat variasi fekunditas dan diameter telur antar jenis ikan terbang, serta lokasi penangkapan ikan terbang yang dilakukan oleh nelayan lokal saat ini merupakan daerah pemijahan. Fish fecundity and egg diameter are essential aspects in the study of fishery biological reproductive. These two aspects were observed on three species of fyingfish Cheilopogon cyanopterus, Hirundichthys oxycephalus, and Parexocoetus mento which collected from fishermen caught used a drift gillnet in the waters of Takalar (Makassar Strait) and Pemuteran (north Bali). Numbers of samples examined were 58 gonads of flyingfish at the third (develop) and fourth (mature) maturity stages. The higest fecundity was in the gonad of Parexocoetusmento, however the highest of fecundity mean was in Hirundichthys oxycephalus. The correlation between fecundity and total length shows a weak relationship, however the correlation between fecundity and gonad weight show a strong relationship. Egg diameter of these three flyingfish species had no significant different, but generally egg diameter of develop gonad (0.33-2.21 mm) was smaller than the mature one (0.45-2.36 mm). This study indicates variability in fecundity and eeg diameter among flyingfish species. In addition, the fishing grounds also indicates spawing grounds.
