Human norovirus is a leading cause of foodborne disease and can be transmitted through many routes, including environmental exposure to fomites. In this study, both the recovery and inactivation of two human norovirus surrogates, feline calicivirus (FCV) and murine norovirus (MNV), on hard nonporous surfaces (glass) and soft porous surfaces (polyester and cotton) were evaluated by both plaque assay and reverse transcription quantitative PCR method. Two disinfectants, sodium hypochlorite (8.25%) and accelerated hydrogen peroxide (AHP, at 4.25%) were evaluated for disinfection efficacy. Five coupons per surface type were used to evaluate the recovery of FCV and MNV by sonication and stomaching and the disinfection of each surface type by using 5 ml of disinfectant for a contact time of 5 min. FCV at an initial titer of ca. 7 log PFU/ml was recovered from glass, cotton, and polyester at 6.2, 5.4, and 3.8 log PFU/ml, respectively, compared with 5.5, 5.2, and 4.1 log PFU/ml, respectively, for MNV with an initial titer of ca. 6 log PFU/ml. The use of sodium hypochlorite (5,000 ppm) was able to inactivate both FCV and MNV (3.1 to 5.5 log PFU/ml) below the limit of detection on all three surface types. AHP (2,656 ppm) inactivated FCV (3.1 to 5.5 log PFU/ml) below the limit of detection for all three surface types but achieved minimal inactivation of MNV (0.17 to 1.37 log PFU/ml). Reduction of viral RNA by sodium hypochlorite corresponded to 2.72 to 4.06 log reduction for FCV and 2.07 to 3.04 log reduction for MNV on all three surface types. Reduction of viral RNA by AHP corresponded to 1.89 to 3.4 log reduction for FCV and 0.54 to 0.85 log reduction for MNV. Our results clearly indicate that both virus and surface types significantly influence recovery efficiency and disinfection efficacy. Based on the performance of our proposed testing method, an improvement in virus recovery will be needed to effectively validate virus disinfection of soft porous surfaces.

Abstract. Late-glacial palaeoclimate reconstructions from deep-sea sediment archives provide valuable insight into past rapid changes in ocean chemistry. Unfortunately, only a small proportion of the ocean floor with sufficiently high sediment accumulation rate (SAR) is suitable for such reconstructions using the long-standing age–depth model approach. We employ ultra-small radiocarbon (14C) dating on single microscopic foraminifera to demonstrate that the long-standing age–depth model method conceals large age uncertainties caused by post-depositional sediment mixing, meaning that existing studies may underestimate total geochronological error. We find that the age–depth distribution of our 14C-dated single foraminifera is in good agreement with existing bioturbation models only after one takes the possibility of Zoophycos burrowing into account. To overcome the problems associated with the age–depth paradigm, we use the first ever dual 14C and stable isotope (δ18O and δ13C) analysis on single microscopic foraminifera to produce a palaeoclimate time series independent of the age–depth paradigm. This new state of the art essentially decouples single foraminifera from the age–depth paradigm to provide multiple floating, temporal snapshots of ocean chemistry, thus allowing for the successful extraction of temporally accurate palaeoclimate data from low-SAR deep-sea archives. This new method can address large geographical gaps in late-glacial benthic palaeoceanographic reconstructions by opening up vast areas of previously disregarded, low-SAR deep-sea archives to research, which will lead to an improved understanding of the global interaction between oceans and climate.

Abstract. The motion of electrically conducting sea water through Earth's magnetic field induces secondary electromagnetic fields. Due to its periodicity, the oceanic tidally induced magnetic field is easily distinguishable in magnetic field measurements and therefore detectable. These tidally induced signatures in the electromagnetic fields are also sensitive to changes in oceanic temperature and salinity distributions. We investigate the impact of oceanic heat and salinity changes related to the El Niño–Southern Oscillation (ENSO) on oceanic tidally induced magnetic fields. Synthetic hydrographic data containing characteristic ENSO dynamics have been derived from a coupled ocean–atmosphere simulation covering a period of 50 years. The corresponding tidally induced magnetic signals have been calculated with the 3-D induction solver x3dg. By means of the Oceanic Niño Index (ONI), based on sea surface temperature anomalies, and a corresponding Magnetic Niño Index (MaNI), based on anomalies in the oceanic tidally induced magnetic field at sea level, we demonstrate that evidence of developing ENSO events can be found in the oceanic magnetic fields statistically 4 months earlier than in sea surface temperatures. The analysis of the spatio-temporal progression of the oceanic magnetic field anomalies offers a deeper understanding on the underlying oceanic processes and is used to test and validate the initial findings.

Access restrictions are essential in standard information systems and became an issue for ontologies in the following two aspects. Ontologies can represent explicit and implicit knowledge about an access policy. For this aspect we provided a methodology to represent and systematically complete role-based access control policies. Orthogonally, an ontology might be available for limited reading access. Independently of a specific ontology language or reasoner, we provided a lattice-based framework to assign labels to an ontology’s axioms and consequences. We looked at the problems to compute and repair one or multiple consequence labels and to assign a query-based access restriction. An empirical evaluation has shown that the algorithms perform well in practical scenarios with large-scale ontologies.

Feeds werden unter anderem eingesetzt, um Nutzer in einem einheitlichen Format und in aggregierter Form über Aktualisierungen oder neue Beiträge auf Webseiten zu informieren. Da bei Feeds in der Regel keine Benachrichtigungsfunktionalitäten angeboten werden, müssen Interessenten Feeds regelmäßig auf Aktualisierungen überprüfen. Die Betrachtung entsprechender Techniken bildet den Kern der Arbeit. Die in den verwandten Domänen Web Crawling und Web Caching eingesetzten Algorithmen zur Vorhersage der Zeitpunkte von Aktualisierungen werden aufgearbeitet und an die spezifischen Anforderungen der Domäne Feeds angepasst. Anschließend wird ein selbst entwickelter Algorithmus vorgestellt, der bereits ohne den Einsatz spezieller Konfigurationsparameter und ohne Trainingsphase im Durchschnitt bessere Vorhersagen trifft, als die übrigen betrachteten Algorithmen. Auf Basis der Analyse verschiedener Metriken zur Beurteilung der Qualität von Vorhersagen erfolgt die Definition eines zusammenfassenden Gütemaßes, welches den Vergleich von Algorithmen anhand eines einzigen Wertes ermöglicht. Darüber hinaus werden abfragespezifische Attribute der Feed-Formate untersucht und es wird empirisch gezeigt, dass die auf der partiellen Historie der Feeds basierende Vorhersage von Änderungen bereits bessere Ergebnisse erzielt, als die Einbeziehung der von den Diensteanbietern bereitgestellten Werte in die Berechnung ermöglicht. Die empirischen Evaluationen erfolgen anhand eines breitgefächerten, realen Feed-Datensatzes, welcher der wissenschaftlichen Gemeinschaft frei zur Verfügung gestellt wird, um den Vergleich mit neuen Algorithmen zu erleichtern.

Die Verwaltung persönlicher, multimedialer Dokumente kann mit Hilfe semantischer Technologien und Ontologien intelligent und effektiv unterstützt werden. Dies setzt jedoch Verfahren voraus, die den grundlegenden Annotations- und Bearbeitungsaufwand für den Anwender minimieren und dabei eine ausreichende Datenqualität und -konsistenz sicherstellen. Im Rahmen der Dissertation wurden notwendige Mechanismen zur semi-automatischen Modellierung und Wartung semantischer Dokumentenbeschreibungen spezifiziert. Diese bildeten die Grundlage für den Entwurf einer komponentenbasierten, anwendungsunabhängigen Architektur als Basis für die Entwicklung innovativer, semantikbasierter Lösungen zur persönlichen Dokumenten- und Wissensverwaltung
Personal multimedia document management benefits from Semantic Web technologies and the application of ontologies. However, an ontology-based document management system has to meet a number of challenges regarding flexibility, soundness, and controllability of the semantic data model. The first part of the dissertation proposes necessary mechanisms for the semi-automatic modeling and maintenance of semantic document descriptions. The second part introduces a component-based, application-independent architecture which forms the basis for the development of innovative, semantic-driven solutions for personal document and information management

The analysis of time-delayed dynamics on networks may help to understand many systems from physics, biology, and engineering, such as coupled laser arrays, gene-regulatory networks and complex ecosystems. Beside the complexity due to the network structure, the analysis is further complicated by the presence of the delays. Delay systems are in general infinite dimensional and thus can display complex dynamics as oscillations and chaos. The mathematical difficulties related to the delays hinders the analysis of delay networks. Thus, little is known yet about basic relations between network structure and delay dynamics. It has been shown that networks without delays can be studied efficiently with the generalized modeling approach, which analyzes the stability of an assumed steady state by a direct parametrization of the Jacobian matrix. In this thesis, I demonstrate the extension of the generalized modeling approach to delay networks and analyze networks of delay-coupled delay oscillators, with delayed auto-catalytic growth on the nodes and delayed transport between nodes. For degree-homogeneous networks (DHONs), in which each node has the same number of links, the bifurcation lines that border the stable areas can be calculated analytically, where the topology of the network is described only by the eigenvalues of the adjacency matrix. For undirected networks, the stability pattern in the parameter space of growth and transport delay is governed by two periodic sets of tongues of instability, which depend on the largest positive and the smallest negative eigenvalue. The direct relation between the eigenvalue and the bifurcation lines allows us to predict stability patterns for networks with certain topological properties. Thus, bipartite networks display a characteristic periodicity of tongues. In order to analyze the stability of degree-heterogeneous networks (DHENs), I apply a numerical sampling method based on Cauchy\'s Argument Principle. The stability patterns of these networks resembles the pattern of DHONs, which is governed by the two periodic sets. For networks with sufficiently many links, one set disappears, and the stability of DHENs can be approximates by the stability of a fully-connected network with the same average degree. However, random DHENs tend to be more stable than DHONs, and DHENs with a broad degree-distribution tend to be more stable than DHENs with a narrow distribution. Thus, such networks are more likely to give rise to amplitude death, i.e. the stabilization of an unstable steady state through diffusive coupling. The stability pattern of DHENs can be qualitatively different than the pattern in DHONs. However, for small growth delays, close to the critical delay of the single node system, the bifurcation lines of all DHENs with the same average degree coincide. This, is particularly interesting, because there the stability depends on a global property of the network, which suggests a diverging interaction length. In summary, the extension of generalized modeling to time-delay networks reveals basic relations between the delay dynamics and the topology. The generality of our model should allow to apply these results to a large class of real-world systems.

Die "Kontextsensitivität" genannte systematische Berücksichtigung von Umweltinformationen durch Anwendungssysteme kann als Querschnittsfunktion im betrieblichen Umfeld in vielen Bereichen einen Nutzen stiften. Wirklich praxistaugliche kontextsensitive Anwendungssysteme, die sich analog zu einem mitdenkenden menschlichen Assistenten harmonisch in die ablaufenden Vorgänge in der Realwelt einbringen, haben einen enormen Bedarf nach umfassenden, d.h. diverse Aspekte der Realwelt beschreibenden Kontextinformationen, die jedoch prinzipbedingt verteilt in verschiedenen Datenquellen, etwa Kontexterfassungssystemen, Endgeräten sowie prinzipiell auch in beliebigen anderen, z.T. bereits existierenden Anwendungen entstehen. Ziel dieser Arbeit ist die Verringerung der Komplexität des Beschaffungsvorganges von verteilten und heterogenen Kontextinformationen durch Bereitstellung einer einfach verwendbaren Methode zur Darstellung eines umfassenden, aus verteilten und heterogenen Datenquellen zusammengetragenen Kontextmodells. Im Besonderen werden durch diese Arbeit zwei Probleme addressiert, zum einen daß ein Konsument von umfassenden Kontextinformationen mehrere Datenquellen sowohl kennen und zugreifen können und zum anderen über die zwischen den einzelnen Kontextinformationen in verschiedenen Datenquellen existierenden, zunächst nicht modellierten semantischen Verbindungen Bescheid wissen muß. Das dazu entwickelte Kontextinformationsintegrations- und -darstellungsverfahren kombiniert daher ein die Beschaffung und Integration von Kontextinformationen aus diversen Datenquellen modellierendes Informationsintegrationsmodell mit einem Kontextdarstellungsmodell, welches die abzubildende Realweltdomäne basierend auf ontologischen Informationen durch in problemspezifischer Weise erweiterte Verfahren des Semantic Web in einer möglichst intuitiven, wiederverwendbaren und modularen Weise modelliert. Nach einer fundierten Anforderungsanalyse des entwickelten Prinzips wird dessen Verwendung und Nutzen basierend auf der Skizzierung der wichtigsten allgemeinen Verwendungsmöglichkeiten von Kontextinformationen im betrieblichen Umfeld anhand eines komplexen betrieblichen Anwendungsszenarios demonstriert. Dieses beinhaltet ein Nutzerprofil, das von diversen Anwendungen, u.a. einem kontextsensitiven KFZ-Navigationssystem, einer Restaurantsuchanwendung sowie einem Touristenführer verwendet wird. Probleme hinsichtlich des Datenschutzes, der Integration in existierende Umgebungen und Abläufe sowie der Skalierbarkeit und Leistungsfähigkeit des Verfahrens werden ebenfalls diskutiert
Context-awareness, which is the systematic consideration of information from the environment of applications, can provide significant benefits in the area of business and technology. To be really useful, i.e. harmonically support real-world processes as human assistants do it, practical applications need a comprehensive and detailed contextual information base that describes all relevant aspects of the real world. As a matter of principle, comprehensive contextual information arises in many places and data sources, e.g. in context-aware infrastructures as well as in "normal" applications, which may have knowledge about the context based on their functionality to support a certain process in the real world. This thesis facilitates the use of contextual information by reducing the complexity of the procurement process of distributed and heterogenous contextual information. Particularly, it addresses the two problems that a consumer of comprehensive contextual information needs to be aware of and able to access several different data sources and must know how to combine the contextual information taken from different and isolated data sources into a meaningful representation of the context. Especially the latter information cannot be modelled using the current state of the art. These problems are addressed by the development of an integration and representation model for contextual information that allows to compose comprehensive context models using information inside distributed and heterogeneous data sources. This model combines an information integration model for distributed and heterogenous information (which consists of an access model for heterogeneous data sources, an integration model and an information relation model) with a representation model for context that formalizes the representation of the respective real world domain, i.e. of the real world objects and their semantic relations in an intuitive, reusable and modular way based on ontologies. The resulting model consists of five layers that represent different aspects of the information integration solution. The achievement of the objectives is rated based on a requirement analysis of the problem domain. The technical feasibility and usefulness of the model is demonstrated by the implementation of an engine to support the approach as well as a complex application scenario consisting of a user profile that integrates information from several data sources and a couple of context-aware applications, e.g. a context-aware navigation system, a restaurant finder application as well as an enhanced tourist guide that use the user profile. Problems regarding security and social effects, the integration of this solution into existing environments and infrastructures as well as technical issues like the scalability and performance of this model are discussed too

In der vorliegenden Arbeit werden Visualisierungsmethoden für das interaktive Erfassen und Strukturieren von Informationen im Kontext der Wissensmodellierung konzipiert und untersucht. Motiviert ist das Vorhaben durch das Interesse von Wissensarbeitern an unterstützenden Werkzeugen sowie von Unternehmen und Institutionen, unstrukturiertes Prozesswissen zu erfassen, zu strukturieren und intern für Optimierungszwecke verfügbar zu machen. Diese Problematik tritt domänenunabhängig auf. Die Herausforderung dabei ist, diese branchenübergreifend zu lösen. Die zwei wesentlichen Nachteile des Wissensmodellierungsprozesses sind zum einen die aufwendige Dateneingabe durch Benutzer und zum anderen der komplizierte Prozess der Wissensformalisierung. In den frühen Phasen bisheriger Arbeitsprozesse der Wissensmodellierung verwenden Wissensarbeiter hauptsächlich Papier und Stift sowie Whiteboards, da digitale Systeme für diesen Zweck häufig zu inflexibel sind. Ziel der vorliegenden Arbeit ist es, einen digitalen Lösungsansatz zu präsentieren, welcher diese nachteiligen Aspekte verbessert. Das Thema wird dabei methodisch in drei Schritten bearbeitet. Zuerst werden aktuelle Arbeitsprozesse der Wissensmodellierung sowie dabei verwendete Hilfsmittel analysiert. Basierend auf diesen Untersuchungen wird als theoretische Lösung die Methode der Freiform-Wissensmodellierung vorgestellt, welche eine Alternative zur Papierform und zu bisherigen digitalen Systemen darstellt. Das erarbeitete Konzept umfasst eine digitale, stiftbasierte Tablet-Computer-Anwendung, welche die Art und Weise der Darstellungen mittels Papier und Stift mit den Vorteilen der Veränderbarkeit und Datenspeicherung digitaler Systeme kombiniert. Um die theoretischen Überlegungen zu untermauern, werden zwei aufeinander aufbauende, prototypische Softwareanwendungen in der vorliegenden Arbeit entwickelt und vorgestellt (Auf Implementierungsarbeiten betreuter Studenten wird an den entsprechenden Stellen im Text verwiesen). Im Rahmen einer Laborstudie wird die entwickelte Methode der Freiform-Wissensmodellierung, welche den Softwareanwendungen zugrunde liegt, mit der Verwendung von Stift und Papier verglichen. Da bis dato keine derartige Vergleichsstudie zwischen Papier und Tablet-Computer gefunden werden konnte, wird anforderungsgeleitet ein spezieller Studienaufbau entwickelt. Dieser kann zukünftig für andere Forschungsvorhaben verwendet werden. Die Ergebnisse belegen, dass die digitale Anwendung zur Freiform-Wissensmodellierung in ihren Möglichkeiten eine hohe Ähnlichkeit zur Verwendung von Papier und Stift aufweist. Sie eignet sich daher in besonderem Maße zur Unterstützung der frühen Phasen der Wissensmodellierung. Basierend auf den Erkenntnissen der Studie werden darüber hinaus Weiterentwicklungsmöglichkeiten aufgezeigt. Für die wichtigsten Kritikpunkte wird ein weiterentwickeltes Konzept vorgestellt. Das Ergebnis der vorliegenden Arbeit ist ein in der Praxis auf Tablet-Computern anwendbares Konzept zur Wissensmodellierung. Dieses steht als prototypische Umsetzung zur Verfügung. Das entwickelte Konzept der Freiform-Wissensmodellierung ermöglicht jedem Benutzer (egal ob Laie oder Experte in grafischer Gestaltung oder in technischer Repräsentation) Gedanken visuell zu strukturieren und diese synchron in einem passenden Datenmodell abzulegen. Durch die Visualisierungsmethode der Freiformen wird die Struktur der Daten und der Aufbau der Informationen bereits durch die visuelle Oberfläche für den Benutzer und das System gleichermaßen „ersichtlich”. Das System erkennt die hierarchische Verschachtelung und Gruppierung von Informationen. Der darunterliegende Aufbau sowie die Struktur der Daten werden vom System grafisch explizit gezeigt, sodass ein Anwender zu jederzeit sieht, welche Struktur das System „verstanden” hat. So kann diese „entindividualisierte” Struktur der Inhalte auch von anderen Benutzern nachvollzogen werden. Dies erlaubt ein grundlegendes kooperatives Arbeiten. Das Konzept der Freiform-Wissensmodellierung ist dabei (ähnlich wie Whiteboards oder Papier und Stift) vom Anwendungsfall unabhängig einsetzbar. Die vorliegende Arbeit bietet einen neuartigen Ansatz, temporäre Informationen bereits im Verlauf der Wissensmodellierung digital festzuhalten und schrittweise weiterzuentwickeln. In der durchgeführten Studie wurden sämtliche von Probanden erstellte Typen grafischer Objekte ermittelt. Zukünftige Forschungsarbeiten können darauf aufbauend die softwareseitige Erkennung und Verarbeitung von handgezeichneten Inhalten verbessern. Somit bietet die vorliegende Arbeit die Grundlage für eine neue Generation unterstützender digitaler Werkzeuge für Wissensarbeiter.

This thesis focuses on entity and fact extraction from the web. Different knowledge representations and techniques for information extraction are discussed before the design for a knowledge extraction system, called WebKnox, is introduced. The main contribution of this thesis is the trust ranking of extracted facts with a self-supervised learning loop and the extraction system with its composition of known and refined extraction algorithms. The used techniques show an improvement in precision and recall in most of the matters for entity and fact extractions compared to the chosen baseline approaches.

Mobile devices such as smartphones and smart watches are ubiquitous companions of humans’ daily life. Since 2014, there are more mobile devices on Earth than humans. Mobile applications utilize sensors and actuators of these devices to support individuals in their daily life. In particular, 24% of the Android applications leverage users’ mobility data. For instance, this data allows applications to understand which places an individual typically visits. This allows providing her with transportation information, location-based advertisements, or to enable smart home heating systems. These and similar scenarios require the possibility to access the Internet from everywhere and at any time. To realize these scenarios 83% of the applications available in the Android Play Store require the Internet to operate properly and therefore access it from everywhere and at any time. Mobile applications such as Google Now or Apple Siri utilize human mobility data to anticipate where a user will go next or which information she is likely to access en route to her destination. However, predicting human mobility is a challenging task. Existing mobility prediction solutions are typically optimized a priori for a particular application scenario and mobility prediction task. There is no approach that allows for automatically composing a mobility prediction solution depending on the underlying prediction task and other parameters. This approach is required to allow mobile devices to support a plethora of mobile applications running on them, while each of the applications support its users by leveraging mobility predictions in a distinct application scenario. Mobile applications rely strongly on the availability of the Internet to work properly. However, mobile cellular network providers are struggling to provide necessary cellular resources. Mobile applications generate a monthly average mobile traffic volume that ranged between 1 GB in Asia and 3.7 GB in North America in 2015. The Ericsson Mobility Report Q1 2016 predicts that by the end of 2021 this mobile traffic volume will experience a 12-fold increase. The consequences are higher costs for both providers and consumers and a reduced quality of service due to congested mobile cellular networks. Several countermeasures can be applied to cope with these problems. For instance, mobile applications apply caching strategies to prefetch application content by predicting which applications will be used next. However, existing solutions suffer from two major shortcomings. They either (1) do not incorporate traffic volume information into their prefetching decisions and thus generate a substantial amount of cellular traffic or (2) require a modification of mobile application code. In this thesis, we present novel human mobility and application usage prediction algorithms for mobile devices. These two major contributions address the aforementioned problems of (1) selecting a human mobility prediction model and (2) prefetching of mobile application content to reduce cellular traffic. First, we address the selection of human mobility prediction models. We report on an extensive analysis of the influence of temporal, spatial, and phone context data on the performance of mobility prediction algorithms. Building upon our analysis results, we present (1) SELECTOR – a novel algorithm for selecting individual human mobility prediction models and (2) MAJOR – an ensemble learning approach for human mobility prediction. Furthermore, we introduce population mobility models and demonstrate their practical applicability. In particular, we analyze techniques that focus on detection of wrong human mobility predictions. Among these techniques, an ensemble learning algorithm, called LOTUS, is designed and evaluated. Second, we present EBC – a novel algorithm for prefetching mobile application content. EBC’s goal is to reduce cellular traffic consumption to improve application content freshness. With respect to existing solutions, EBC presents novel techniques (1) to incorporate different strategies for prefetching mobile applications depending on the available network type and (2) to incorporate application traffic volume predictions into the prefetching decisions. EBC also achieves a reduction in application launch time to the cost of a negligible increase in energy consumption. Developing human mobility and application usage prediction algorithms requires access to human mobility and application usage data. To this end, we leverage in this thesis three publicly available data set. Furthermore, we address the shortcomings of these data sets, namely, (1) the lack of ground-truth mobility data and (2) the lack of human mobility data at short-term events like conferences. We contribute with JK2013 and UbiComp Data Collection Campaign (UbiDCC) two human mobility data sets that address these shortcomings. We also develop and make publicly available a mobile application called LOCATOR, which was used to collect our data sets. In summary, the contributions of this thesis provide a step further towards supporting mobile applications and their users. With SELECTOR, we contribute an algorithm that allows optimizing the quality of human mobility predictions by appropriately selecting parameters. To reduce the cellular traffic footprint of mobile applications, we contribute with EBC a novel approach for prefetching of mobile application content by leveraging application usage predictions. Furthermore, we provide insights about how and to what extent wrong and uncertain human mobility predictions can be detected. Lastly, with our mobile application LOCATOR and two human mobility data sets, we contribute practical tools for researchers in the human mobility prediction domain.

IN SOME WAYS, Ezra–Nehemiah is a companion piece to Esther, another story of Jews living as vassals of the Persian Empire, although it has none of the patent absurdity of Esther. Nehemiah’s story, like Esther’s, starts in a Persian court, but most of the composite story takes place in Jerusalem. Cyrus “the Great,” the first ruler from the Achaemenid dynasty, in the first year after his conquest of the Neo-Babylonian Empire in 539 BCE issued a decree that allowed Jews to rebuild the temple (Ezra 1:1–4). The decree marked a policy of granting provinces a greater measure of local and regional control in exchange for cooperation with imperial economic and political goals. The book covers a period that exceeds the life of the two individuals for whom Ezra–Nehemiah is named. Four or five Persian kings are mentioned—Cyrus, Darius, Ahasuerus/Xerxes, Artaxerxes I, and maybe Artaxerxes II (Ezra 4:5–7; 6:14)—whose reigns span more than a century (c. 538–400 BCE). The book makes no consistent attempt to specify the chronology. The so-called Nehemiah memoir is considered by some the oldest and most accurately historical part of the book, recording the experience of a highly placed imperial agent. It suggests that some twenty years into the reign of Artaxerxes I (445 BCE), Jerusalem was still largely in ruins (Neh 2:3), even if the temple had been reconstructed two or three generations earlier (c. 515 BCE) at the urging of the prophet Haggai....

Huanfeng Jiang at the South China University of Technology developed (J. Am. Chem. Soc. 2013, 135, 5286) the palladium-catalyzed dehydrogenative aminohalogenation of methyl acrylate with aniline 1. A 1,3-hydrogen shift/ chlorination catalyzed by an iridium complex was reported (Angew. Chem. Int. Ed. 2013, 52, 6273) by Belén Martín- Matute at Stockholm University. Robert M. Waymouth discovered (J. Am. Chem. Soc. 2013, 135, 7593) the chemoselective oxidation of polyol 5 by a cationic palladium species. A ruthenium(II) hydride was found to catalyze the conversion of alcohols such as 7 to carboxylic acids using water as the oxygen source as disclosed (Nature Chem. 2013, 5, 122) by David Milstein at the Weizmann Institute of Science in Israel. Susan K. Hanson at the Los Alamos National Laboratory in New Mexico reported (Org. Lett. 2013, 15, 650) the acceptorless dehydrogenation of alcohols catalyzed by cobalt complex 12 to form imines such as 13 upon reaction with an amine. A collaboration led by Pedro J. Pérez at the University of Huelva in Spain studied (J. Am. Chem. Soc. 2013, 135, 3887) the oxidation of alkanes under catalysis with copper complex 15, primarily yielding alcohols and ketones, such as in the conversion of cyclohexane (14) to cyclohexanol (16) and cyclohexanone (17). A remarkable symmetry-breaking Wacker oxidation of diene 18 to produce 19 was the key step in the total synthesis of (+)-obolactone reported (Org. Lett. 2013, 15, 1294) by Reinhard Brückner at the University of Freiburg in Germany. Kiyotomi Kaneda at the University of Osaka found (Angew. Chem. Int. Ed. 2013, 52, 5961) that a palladium salt catalyzes the conversion of electron-deficient internal olefin 20 to ketone 21. As part of a program to develop environmentally sustainable procedures, Caterina Fusco at the University of Bari in Italy described (Tetrahedron Lett. 2013, 54, 515) the oxidative cleavage of lactam 22 by methyl(trifluoromethyl)dioxirane in water to produce ω-nitro acid 24. Motomu Kanai at the University of Tokyo reported (Org. Lett. 2013, 15, 1918) the β-functionalization of tertiary aromatic amine 25 with nitroolefin 26 to produce 27 by iron catalysis.
