Architectural Record 1942-1967

description: This PhD thesis examines the editorial policies and publishing history of the American periodical Architectural Record in the quarter century from 1942 to 1967. Operating since 1891, the Architectural Record is the longest-living and most circulated professional magazine of architecture, with a strong and lasting impact on the development of the discipline and the profession in the US and abroad. As an archive of architectural knowledge, its history during the mid-20th century is revealing the paradigm shift that occurred in-between the emergence of Modernism in pre-war Europe and its transition to Post-Modernism in the second half of the 20th c., as a largely American issue. The success and influence of the magazine was due to the resources of its parent corporations, F.W. Dodge and McGraw-Hill, its support and acknowledgement by professional and academic organizations and the connections, commitment and inventiveness of its editors. The editorial campaigns of the magazine trace the struggle for the adaptation of the modern movement in the American context and through that to its subsequent global eminence as “contemporary architecture,” a term popularised by the Record. In the midst of the media revolution, the architectural magazines saw the transformation of the profession to an information-based business, beyond an art and an engineering science. At a time when “architectural composition” was redefined into “architectural design.” Amongst the greater media revolution emerging aggressively in the US, the Architectural Record undertook the task of catering for the needs of the practising architect in the post-industrial, managerial and information age. And while initially the magazines were following the architectural developments, reporting on literal images of architecture, by 1967 its editors were educating, managing, consulting and navigating the profession trough its new markets. This trajectory pinackled in the Record's editorial campaign for “the image of the architect” that exemplified the phenomenon of how magazines were lobbying for the profession. A phenomenon that is still largely inexplored and that defines 21st architectural practice and design. But more than any theoretical sub-narrative, this thesis is dedicated to the history of the people and events that took place behind the pages of this era-defining magazine through the archives and living records of their time.

description: In this work, a deeper understanding of the electrochemical oxidation at SOFC anodes was gained by the experimental characterization of patterned Ni anodes in H2-H2O and CO-CO2 atmosphere. By high resolution data analysis, the Line Specific Resistance attributed to charge transfer and its dependencies on gas composition, temperature and polarization voltage were identified. Furthermore, the comparison of the performance of patterned and cermet anodes was enabled using a transmission line model.

Countercurrent Heat Exchange Building Envelope Using Ceramic Components
Creators: name: Vollen, Jason Oliver
Publisher: name: A+BE | Architecture and the Built Environment
Year: 2020

description: Research and development in building envelope design have promoted the convergence of two system types, Thermo-Active Building Systems and Adaptive Building Envelopes, that re- conceptualize the envelope as a distributed energy transfer function that captures, transforms, stores, and even re-distributes energy resources. The widespread deployment of Thermo-Active Building Systems as a building envelope will depend on several factors. These factors include the value of the design attributes that impact energy transfer in relation to the performance of the building envelope assembly and the return on investment that these attributes individually or in the aggregate can provide as a reduction in Energy Use Intensity. The research focus is on the design development, testing, and energy reduction potential of a Thermo-Active Building System as an adaptive countercurrent energy exchange envelope system using ceramic components: the Thermal Adaptive Ceramic Envelope.

Year: 2008

description: Objective: To determine if subject score on the SICK Scapula, Static Measurements, 0 to 20 Point Rating Scale1 can be predicted from scapular stabilizer muscle activation. Design: Quasi-experimental, one group design with a counterbalancing of two functional tasks. Subjects: NCAA Division I and/or recreational club overhead athletes (n = 40). Measurements: The SICK Scapula, Static Measurements, 0 to 20 Point Rating Scale(1) was used for assessing the severity of scapular malposition. Muscle activation was recorded for the upper trapezius, middle trapezius, lower trapezius, and serratus anterior muscles. Results: Regression analyses revealed that scapular stabilizer muscle activation amplitude did not significantly predict the subject score on the SICK Scapula, Static Measurements, 0 to 20 Point Rating Scale.(1) Conclusion: In overhead athletes, mean muscle activation amplitude of the scapular stabilizers was not found to be valid predictor of subject score on the SICK Scapula, Static Measurements, 0 to 20 Point Rating Scale.(1)

description: The regulation of vertebrate acid–base balance during acute episodes of elevated internal PCO2 is typically characterized by extracellular pH (pHe) regulation. Changes in pHe are associated with qualitatively similar changes in intracellular tissue pH (pHi) as the two are typically coupled, referred to as ‘coupled pH regulation’. However, not all vertebrates rely on coupled pH regulation; instead, some preferentially regulate pHi against severe and maintained reductions in pHe. Preferential pHi regulation has been identified in several adult fish species and an aquatic amphibian, but never in adult amniotes. Recently, common snapping turtles were observed to preferentially regulate pHi during development; the pattern of acid–base regulation in these species shifts from preferential pHi regulation in embryos to coupled pH regulation in adults. In this Commentary, we discuss the hypothesis that preferential pHi regulation may be a general strategy employed by vertebrate embryos in order to maintain acid–base homeostasis during severe acute acid–base disturbances. In adult vertebrates, the retention or loss of preferential pHi regulation may depend on selection pressures associated with the environment inhabited and/or the severity of acid–base regulatory challenges to which they are exposed. We also consider the idea that the retention of preferential pHi regulation into adulthood may have been a key event in vertebrate evolution, with implications for the invasion of freshwater habitats, the evolution of air breathing and the transition of vertebrates from water to land.

description: ExbB and ExbD are cytoplasmic membrane proteins that associate with TonB to convey the energy of the proton-motive force to outer membrane receptors in Gram-negative bacteria for iron uptake. The opportunistic pathogen Serratia marcescens (Sm) possesses both TonB and a heme-specific TonB paralog, HasB. ExbBSm has a long periplasmic extension absent in other bacteria such as E. coli (Ec). Long ExbB’s are found in several genera of Alphaproteobacteria, most often in correlation with a hasB gene. We investigated specificity determinants of ExbBSm and HasB. We determined the cryo-EM structures of ExbBSm and of the ExbB-ExbDSm complex from S. marcescens. ExbBSm alone is a stable pentamer, and its complex includes two ExbD monomers. We showed that ExbBSm extension interacts with HasB and is involved in heme acquisition and we identified key residues in the membrane domain of ExbBSm and ExbBEc, essential for function and likely involved in the interaction with TonB/HasB. Our results shed light on the class of inner membrane energy machinery formed by ExbB, ExbD and HasB.

description: We consider the problem of solving consensus using deterministic algorithms in a synchronous dynamic network with unreliable, directional point-to-point links, which are under the control of a message adversary. In contrast to a large body of existing work that focuses on oblivious message adversaries where the communication graphs are picked from a predefined set, we consider message adversaries where guarantees about stable periods that occur only eventually can be expressed. We reveal to what extent such eventual stability is necessary and sufficient, that is, we present the shortest period of stability that permits solving consensus, a result that should prove quite useful in systems that exhibit erratic boot-up phases or recover after repeatedly occurring, massive transient faults. Contrary to the case of longer stability periods, where we show how standard algorithmic techniques for solving consensus can be employed, the short-lived nature of the stability phase forces us to use more unusual algorithmic methods that avoid waiting explicitly for the stability period to occur.

description: This paper shows a study on energetic consumption of BTSs (Base Transceiver Stations) for mobile communication, related to conditioning functions. An energetic "thermal model" of a telecommunication station is proposed and studied. The results have been validated with a BTS in central Italy, showing good agreement. Findings show a substantial high internal-external temperature difference in the containing shelter, particularly during daytime and warm months, due to sources of heat (equipment, external temperature and sun radiation) and to the difficulty in spread the warmth out. The necessity to keep the operating temperatures within a given range for the correct functioning of the electronic equipment requires the use of conditioning setups, and this significantly increases the energetic demand of the whole system. The analysis of thermal flows across the shelter can help to gather further data on its temperature behavior and to devise practical measures to lower the power demand, while keeping the operating parameters in the suggested ranges. The investigation of some operating parameters of the equipment and of the shelter, such as threshold set-points, air vent area, external wall transmittance and reflectivity, suggests annual energy savings between 10% and 30%.

The proof is based on the recent message passing representation of SIR epidemics applied to a complete graph.

description: We present [C/Fe] and [N/Fe] abundance ratios and CH(λ4300) and S(λ3883) index measurements for 94 red giant branch (RGB) stars in the Sculptor dwarf spheroidal galaxy from VLT/VIMOS MOS observations at a resolving power R= 1150 at 4020 Å. This is the first time that [N/Fe] abundances are derived for a large number of stars in a dwarf spheroidal. We found a trend for the [C/Fe] abundance to decrease with increasing luminosity on the RGB across the whole metallicity range, a phenomenon observed in both field and globular cluster giants, which can be interpreted in the framework of evolutionary mixing of partially processed CNO material. Both our measurements of [C/Fe] and [N/Fe] are in good agreement with the theoretical predictions for stars at similar luminosity and metallicity. We detected a dispersion in the carbon abundance at a given [Fe/H], which cannot be ascribed to measurement uncertainties alone. We interpret this observational evidence as the result of the contribution of different nucleosynthesis sources over time to a not well-mixed interstellar medium. We report the discovery of two new carbon-enhanced, metal-poor stars. These are likely the result of pollution from material enriched by asymptotic giant branch stars, as indicated by our estimates of [Ba/Fe]> +1. We also attempted a search for dissolved globular clusters in the field of the galaxy by looking for the distinctive C-N pattern of second population globular clusters stars in a previously detected, very metal-poor, chemodynamical substructure. We do not detect chemical anomalies among this group of stars. However, small number statistics and limited spatial coverage do not allow us to exclude the hypotheses that this substructure forms part of a tidally shredded globular cluster.

Modelling a Population in a Moving Habitat

Climate change

description: The earth’s climate is increasing in temperature and as a result many species’ habitat ranges are shifting. The shift in habitat ranges threatens the local persistence of many species. Mathematical models that capture this phenomena of range shift do so by considering a bounded domain that has a time dependant location on the real line. The analysis on persistence conditions has been considered in both continuous-time and -space, and discrete-time, continuous-space settings. In both model types density was considered to be continuous across the boundaries. However it has been shown that many species exhibit particular behaviour at habitat edges, such as biased movement towards the more suitable habitat. This behaviour should be incorporated into the analysis to obtain more accurate persistence conditions. In this thesis persistence conditions are obtained for generalized boundary conditions with a continuous-time and -space model for a range-shifting habitat. It is shown that a high preference for the suitable habitat at the trailing edge can greatly reduce the size of suitable habitat required for species persistence. As well, for fast shifting ranges, a high preference at the trailing edge is crucial for persistence.
Nitrification in Fixed Bed Reactors Treating Saline Wastewater

description: Two fixed bed reactors for nitrification with either polyethylene/clay sinter lamellas (FBR A) or porous ceramic rings (FBR B) were continously run for treating synthetic saline wastewater. Seawater from Hafen Büsum was used as an inoculums. The performance of the system was evaluated under different operating conditions. A better overall nitrification without nitrite accumulation was observed in FBR B during continuous incubation. However, in term of ammonia (AOR) and nitrite oxidation rates (NOR) that were determined in batch incubations, FBR A revealed a higher AOR and NOR of 6 and 7 mg N L-1 h-1, compared to the AOR and NOR of 5 and 5.9 mg N L-1 h-1 in FBR B, respectively. For studies of the effect of fluctuating salinity on the nitrification, polyethylene/clay sinter lamellas or porous ceramic rings from FBR A and B, respectively, were used as a source of immobilized nitrifiers. Salt concentrations were decreased from 3.5% to 0.03% via 2, 1 and 0.5% and increased from 3.5% to 5, 7 and 9%. A similar result for AOR and NOR during batch incubation was obtained for both substrata in FBR A and FBR B. The salinity changes influenced more the nitrite oxidizing bacteria (NOB) than the ammonia oxidizing bacteria (AOB). Measurement of oxidation rates during changing conditions show that the NORs were always higher than the AORs in all reactors, especially in initial phase. However, NORs were more sensitive to the salinity fluctuation than AORs, especially at lower salinity. The AORs remained constant for 0.5-3.5% NaCl and dropped to 70% and 68.5% after the salt concentration was brought to 0.034 or 5%, respectively. The NORs decreased significantly to 62% and 87.5% of initial rates after the salt concentration was changed to 2 and 5%, respectively. Non-halotolerant nitrifiers reactors with fresh polyethylene/clay as supporting material were inoculated with water samples taken from a "Brackwasser"-location at the North Sea and were continuously run. The salt content in medium was 0% at the start and was then increased up to 10.5%. Increases of the salt concentration in a non-salt-adapted FBR suppressed more to NOR than AOR. When salinity was increased from 0.03% to 0.5, 1 and 2%, AORs remained constant. The AORs were approx. 90% of initial rates after the salt concentrations were increased stepwise to 3.5%, whereas the NORs decreased to 85, 52 and 36% of initial rate after salinity was increased to 1, 2 and 3.5%, respectively.

description: This paper considers the beamforming design for a multiuser multiple-input single-output (MISO) downlink with an arbitrary number of (context-specific) shaping constraints. In this setup, the state-of-the-art beamforming schemes cannot attain the well-known performance bound promised by the semidefinite program (SDP) relaxation technique. To close the gap, we propose a redundant-signal embedded linear beamforming (REEL-BF) scheme, where each user is assigned with one information beamformer and several shaping beamformers. It is shown that the proposed REEL-BF scheme can perform general rank-$K$ beamforming for user symbols in a low-complexity and structured manner. In addition, sufficient conditions are derived to guarantee that the REEL-BF scheme always achieves the SDP bound for linear beamforming schemes. Based on such conditions, an efficient algorithm is then developed to obtain the optimal REEL-BF solution in polynomial time. Numerical results demonstrate that the proposed scheme enjoys substantial performance gains over the existing alternatives.

Recruitment of dentists by military services: implications for academia
Creators: name: Hsu, Ronald Hsien-Jung

Year: 2006

description: This study seeks to explore the perceptions of senior dental students and junior military dental officers regarding their choice of a military career to identify the recruitment methodologies that influenced their decisions, and to determine if these strategies might suggest ways of increasing recruitment for dental academia. Official documentation of activities related to recruitment was requested from the military services. In-depth telephone interviews were conducted to gather qualitative data from senior dental students and junior military dental officers. The interviews suggest that, although obtaining a dental education paid for by military scholarship was a dominant factor, other inducements to sign with the military included: guaranteed employment upon graduation; the prestige associated with the military; access to post graduate training; minimal practice management concerns; and opportunities for continue education. A career in dental education can offer similar incentives, and students may choose academia as a career if the incentives are emphasized.

description: Der Bausektor ist für einen beträchtlichen Teil des Primärenergieverbrauchs und des Aussto-ßes an Treibhausgasen in Europa verantwortlich. Dem Neubau kommt deshalb bei der Ent-wicklung von großen Bauprojekten eine entscheidende Rolle zu, um den Primärenergiebe-darf sowie den Ausstoß an Treibhausgasen zu reduzieren. Wenn alle Neubauten als „Fast-Null-Energiehäuser“ geplant werden, und sich damit der Energiebedarf in der Betriebsphase reduziert, wird sich eine Verschiebung der Effizienzoptimierung hin zur Erstellungsphase der Gebäude, und damit zu den verbauten Materialien und deren ökologischem Einfluss auf Her-stellung und Rückbau vollziehen. Die Material- und Konstruktionswahl der Gebäude rückt somit in das Zentrum der Betrachtung. Durch den Einsatz nachwachsender Rohstoffe im Baubereich können aufgrund der Speicherwirkung biogenen Kohlenstoffs in Holzprodukten CO2-Emissionen eingespart werden. Über die Beschreibung und anschließende Vorgabe von Kenn- und Zielwerten für den Anteil an nachwachsenden Rohstoffen im Neubau kann die Vorentwurfsplanung beeinflusst wer-den. Für die Realisierung der Ressourceneffizienz- und CO2-Einsparungsziele bietet sich der mo-derne Holzbau an, für den es allerdings bis jetzt keine durchgängigen Verfahren gibt, wie sich die Anforderungen an zu errichtende Gebäude nach ökologischen Kriterien über den Pla-nungsprozess umsetzen lassen. Anhand bestehender Gebäude aus verschiedenen Holzkon-struktionen - Massivholzbau, Holzrahmenbau/ Holztafelbau, Hybridbau - werden im Rahmen dieses Projektes Kenn- und Zielwerte für die Menge an nachwachsenden Rohstoffen für die Herstellungsphase der Gebäude ermittelt und festgeschrieben. Die Kennwerte werden für die Umsetzung einer ökologischen Mustersiedlung „Prinz-Eugen-Park“ auf dem ehemaligen Ka-sernengelände der Prinz-Eugen-Kaserne in München in die Ausschreibungsunterlagen der Baufelder integriert, mit dem Ziel den urbanen Holzbau in der Stadt weiter voranzubringen. Der Brandschutz bildet bei der Umsetzung von urbanem mehrgeschossigem Holzbau eine zentrale Rolle, weshalb in diesem Projekt die Umsetzung brandschutzrelevanter Themen de-tailliert dargestellt werden. In Zusammenarbeit mit der Brandschutzdienststelle der LH Mün-chen wurden Lösungsmöglichkeiten aufgezeigt, wie die Anforderungen trotz einer Abwei-chung vom geltenden Baurecht erfüllt und mögliche Ausführungsvarianten in den frühen Pla-nungsphasen eingearbeitet werden können

The thesis uses nationwide data while focusing on the individual experiences of nurses in North Carolina. The first article focuses on job-related risk factors that contribute to musculoskeletal injuries and the costs of these injuries to employers, nurses and patients. The second article looks at actions by legislators, health administrators, nursing organizations and nursing educators to safeguard nurses in the workplace and to reduce the incidence of musculoskeletal injuries. The third article is a profile of a nurse who became addicted to prescription pain medication after injuring her back.

description: Very little is known about how the nature of expertise in introductory and advanced courses compares in knowledge-rich domains such as physics. We develop a framework to compare the similarities and differences between learning and patterns of student difficulties in introductory physics and quantum mechanics. Based upon our framework, we argue that the qualitative patterns of student reasoning difficulties in introductory physics bear a striking resemblance to those found for upper-level quantum mechanics. The framework can guide the design of teaching and learning tools.

description: Heutige Architekturen von PLM-Lösungen sind überwiegend Client-Server orientiert. Mittelfristig wird sich hier eine offene, flexible-Architektur wie Service-orientierte Architekturen (SOA) durchsetzen. Dabei werden die PLM-Funktionen als Services zur Ausführung prozessrelevanter Tätigkeiten angeboten. Daraus ergibt sich ein service-basierter Ansatz für das PLM. Die Kombination von PLM und SOA kann so Unternehmen helfen, ihre bestehenden Infrastrukturen im Laufe der Zeit schrittweise aufzubauen.

description: In this paper, we present a modelling experiment developed to study systems of cities and processes of urbanisation in large territories over long time spans. Building on geographical theories of urban evolution, we rely on agent-based models to 1/ formalise complementary and alternative hypotheses of urbanisation and 2/ explore their ability to simulate observed patterns in a virtual laboratory. The paper is therefore divided into two sections : an overview of the mechanisms implemented to represent competing hypotheses used to simulate urban evolution; and an evaluation of the resulting model structures in their ability to simulate - efficiently and parsimoniously - a system of cities (the Former Soviet Union) over several periods of time (before and after the crash of the USSR). We do so using a modular framework of model-building and evolutionary algorithms for the calibration of several model structures. This project aims at tackling equifinality in systems dynamics by confronting different mechanisms with similar evaluation criteria. It enables the identification of the best-performing models with respect to the chosen criteria by scanning automatically the parameter along with the space of model structures (as combinations of modelled dynamics).

description: We consider a large class of geodesic metric spaces, including Banach spaces, hyperbolic spaces and geodesic $\mathrm{CAT}(κ)$-spaces, and investigate the space of nonexpansive mappings on either a convex or a star-shaped subset in these settings. We prove that the strict contractions form a negligible subset of this space in the sense that they form a $σ$-porous subset. For separable metric spaces we show that a generic nonexpansive mapping has Lipschitz constant one at typical points of its domain. These results contain the case of nonexpansive self-mappings and the case of nonexpansive set-valued mappings as particular cases.

description: Engineering materials show a pronounced heterogeneity on a smaller scale that influences the macroscopic constitutive behavior. Algorithms for the periodic discretization of microstructures are presented. These are used within the Nonuniform Transformation Field Analysis (NTFA) which is an order reduction based nonlinear homogenization method with micro-mechanical background. Theoretical and numerical aspects of the method are discussed and its computational efficiency is validated.
Investigating Student Difficulties with Dirac Notation

description: Quantum mechanics is challenging even for advanced undergraduate and graduate students. Dirac notation is a convenient notation used extensively in quantum mechanics. We have been investigating the difficulties that the advanced undergraduate and graduate students have with Dirac notation. We administered written free response and multiple-choice questions to students and also conducted semi-structured individual interviews with 23 students using a think-aloud protocol to obtain a better understanding of the rationale behind their responses. We find that many students struggle with Dirac notation and they are not consistent in using this notation across various questions in a given test. In particular, whether they answer questions involving Dirac notation correctly or not is context dependent.

description: The amazing possibility of magnetoelectric crystals to cross couple electric and magnetic properties without the need of time-dependent Maxwell's equations has attracted a lot of interest in material science. This enthusiasm has re-emerged during the last decade where magnetoelectric and multiferroic crystals have captivated a tremendous number of studies, mostly driven by the quest of low-power-consumption spintronic devices. While several new candidates have been discovered, the desirable magnetoelectric coupling at room temperature is still sparse and calls for new promising candidates. Here, we show from first-principles studies that the troilite phase of the iron sulfide based compounds, one of the most common mineral of Earth, Moon, Mars or meteors, is magnetoelectric up to temperatures as high as 415 K.

description: Background: For decades, researchers have been striving to better understand the complex mix of factors underlying post-combat mental illness, in the hope of enabling better outcomes for military personnel. This study focuses on investigating the behavior and possible interaction of two risk factors for poor mental health post-deployment to a combat mission: adverse childhood experience (ACE) and deployment-related stressful experience (DRSE). Methods: A longitudinal dataset linking data from 3302 military personnel at recruitment to data collected post-deployment to Canada’s mission in Afghanistan was analysed, using novel scoring systems for exposure classification. Results: Significant ACE-DRSE interaction terms were found in relation to SF-36 MCS, depression and suicidal ideation: the negative effect DRSE had on mental health outcomes was amplified as ACE levels increased. Conclusion: Individuals with a history of childhood adversity are more susceptible to the negative mental health impacts of stressful experiences during deployment to a combat zone.
Feeling “Hangry”: When Hunger is Conceptualized as Emotion
Creators: name: MacCormack, Jennifer
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Many of us have felt “hangry” before, but little research has explored its psychological mechanisms. We hypothesized that feeling “hangry” occurs when participants (N=653) associate bodily feelings with the context, interpreting hunger as high arousal, negative emotions. Studies 1 and 2 used an Affect Misattribution Procedure (Payne et al., 2005) to demonstrate that hungry participants are more likely to experience ambiguous stimuli as negative when seen in a negative context. In Study 3, we demonstrated that this effect occurs when participants are not explicitly focused on emotions. We manipulated hunger vs. satiation and participants’ accessibility to emotion concepts (anger vs. sadness vs. no emotion) prior to placing them in a frustrating situation. As predicted, hungry participants who did not have access to emotion concepts reported greater negative, high arousal emotions and more negative interpersonal perceptions. Implications for emotion theory are discussed.
