description: As the biggest commercial city in Tanzania today, Dar es Salaam features a number of German colonial memory sites which range from buildings, statues to open spaces. Formerly existing as a small caravan town exclusively owned by the Arab Sultan of Zanzibar, Dar es Salaam was further developed by the Germans who used it as their capital (Hauptstadt) beginning in the late 19th century. After the WWI, the city continued to serve as the capital in British mandate period until it was inherited by the independent government of Tanzania in 1961.

Climate risks, environmental regulations, and corporate environmental management
Creators: name: Dang, Hang
Publisher: name: The Australian National University
Year: 2023

description: Scholars have shown an increased interest in studying impacts of environmental risks and opportunities on business firms. Across various strands of the literature on this topic, however, there is still sizeable theoretical and empirical ambiguity around the direction of their impacts and underlying causal mechanisms. As such, this dissertation aims to investigate how different environmental risks and opportunities, such as natural disasters and environmental regulations, affect business firms and their resulting environmental management strategies. The first of the three studies in this dissertation examines the effects of natural disasters on firm productivity. The second study investigates how air pollution policies impact labour productivity. The third study focuses on business responses to environmental compliance requirements and how these strategies affect firm innovation. Taken together, the studies in this dissertation contribute to the overall theme of climate risks, environmental regulations, and business firms. Each study extends the boundary of the theories on economic impacts of natural disasters (study 1), labour effects of environmental policies (study 2), and corporate environmental strategy (study 3). The studies also offer important practical insights for policymakers and managers with respect to decisions and policies involving the effects of environmental risks and opportunities on businesses.

description: We discuss the main features of dilaton interactions for fundamental and effective dilaton fields. In particular, we elaborate on the various ways in which dilatons can couple to the Standard Model and on the role played by the conformal anomaly as a way to characterize their interactions. In the case of a dilaton derived from a metric compactification (graviscalar), we present the structure of the radiative corrections to its decay into two photons, a photon and a $Z$, two $Z$ gauge bosons and two gluons, together with their renormalization properties. We prove that, in the electroweak sector, the renormalization of the theory is guaranteed only if the Higgs is conformally coupled. For such a dilaton, its coupling to the trace anomaly is quite general, and determines, for instance, an enhancement of its decay rates into two photons and two gluons. We then turn our attention to theories containing a non-gravitational (effective) dilaton, which, in our perturbative analysis, manifests as a pseudo-Nambu Goldstone mode of the dilatation current ($J_D$). The infrared coupling of such a state to the two-photons and to the two-gluons sector, and the corresponding anomaly enhancements of its decay rates in these channels, is critically analyzed.

description: We conduct an experimental investigation of temperature dependence of spin diffusion length in highly-doped n-type silicon by using a non-local 3-terminal method. Whereas an effect of spin drift is not ignorable to bias- and temperature-dependence of spin signals in non-metallic systems except for the case of a non-local 4-terminal method, it is not fully conclusive how the spin drift affects spin transport properties in highly-doped Si in a non-local 3-terminal method that is often used in Si spintronics. Here, we report on temperature dependence of spin diffusion length in the Si, and it is clarified that the spin transport is less affected by an external electric field.

title: Magnification Loupes in U.S. Entry-Level Dental Hygiene Programs
Creators: name: Congdon, Leslie McHaney
Publisher: name: Old Dominion University Libraries
Year: 2011

description: Purpose: The purpose of this study was to determine policies and practices regarding magnification loupes among accredited dental hygiene programs as measured by a 31- item, self-designed questionnaire titled Magnifying Loupes in U.S. Entry Level Dental Hygiene Programs. In addition, the study compared policies among dental hygiene programs in two year versus four year programs in terms of requirements for the use of magnification loupes.

Methods: After institutional review board approval, the questionnaire was emailed via Survey Monkey to 303 entry-level dental hygiene programs. An overall response rate of 75% was obtained. Data were analyzed using descriptive statistics and chi-square test of independence.

Results: Results reveal the vast majority of programs do not require loupes for faculty or students with only 23% ofresponding schools requiring students to purchase loupes and 8% requiring faculty to use loupes. More dental hygiene programs require students to wear loupes than require faculty to wear loupes. No statistically significant differences (p-value = 0.54) in program policies were found requiring the purchase of magnifying loupes by students, based on 2-year and 4-year dental hygiene educational programs. Odds ratio (1.25) gives the likelihood of students purchasing loupes in a 2-year program as 25% higher than a 4-year program. Almost two-thirds of the respondents reported loupes instruction as a curriculum component although most respondents spent two or less hours teaching in this area. Most programs (90%) do not plan to require students to purchase loupes in the future although the majority (72.9%) agrees or strongly agrees the proper use of loupes should be integrated in the curriculum.

Conclusions: Most respondents (98.7%) identify advantages to loupes, but clinical policies on loupes do not appear to correlate with beliefs. Educational programs in dental hygiene seem slow to adopt and require the use of loupes. Current clinical polices on loupes should be reviewed to ensure graduates experience the potential ergonomic benefits magnification brings to clinical practice during their education.

description: With quantum Monte Carlo methods, we investigate the consequences of placing a magnetic adatom adjacent to a vacancy in a graphene sheet. We find that instead of the adatom properties depending on the energy of the adatom orbital, as in a single impurity problem, they develop a dependence on the energy of the split localized state associated with the single vacancy problem. Shifting the chemical potential through this experimentally more accessible energy scale reveals novel behavior in the spectral density, magnetic susceptibility, and the correlations of the adatom spin and charge with those of the conduction electrons. In general, the behavior of the adatom in the presence of a vacancy differs significantly from its behavior in the absence of a vacancy.

description: Ende der 1970er Jahre tauchte »Preußen« in beiden deutschen Staaten wieder auf. Die »Preußenrenaissance« wurde bislang vor allem als geschichtspolitisches und intellektuellengeschichtliches Phänomen betrachtet. Preußen wurde aber auch, das zeigt der Blick auf die formative Phase der Preußenkonjunktur um 1980, in breiten Bevölkerungsschichten populär. Der nach 1989/90 betriebene Versuch indes, Preußen zur Traditionsstiftung für das vereinigte Deutschland zu nutzen, scheiterte auf lange Sicht. Heute ist Preußen, jenseits der Hohenzollerndebatte, nurmehr punktuell im Rhythmus der Jahrestage präsent.
Charge and Spin Transport in Magnetic Tunnel Junctions: Microscopic Theory

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We study the charge and spin currents passing through a magnetic tunnel junction (MTJ) on the basis of a tight-binding model. The currents are evaluated perturbatively with respect to the tunnel Hamiltonian. The charge current has the form $A[\bm M_1(t)\times\dot{\bm M}_1(t)]\cdot\bm M_2+B\dot{\bm M}_1(t)\cdot\bm M_2$, where $\bm M_1(t)$ and $\bm M_2$ denote the directions of the magnetization in the free layer and fixed layer, respectively. The constant $A$ vanishes when one or both layers are insulators, {while the constant $B$ disappears when both layers are insulators or the same ferromagnets.} The first term in the expression for charge current represents dissipation driven by the effective electric field induced by the dynamic magnetization. In addition, from an investigation of the spin current, we obtain the microscopic expression for the enhanced Gilbert damping constant $\varDelta α$. We show that $\varDeltaα$ is proportional to the tunnel conductance and depends on the bias voltage.

Primordial black hole formation in the early universe: critical behaviour and self-similarity

description: Following on after three previous papers discussing the formation of primordial black holes during the radiative era of the early universe, we present here a further investigation of the critical nature of the process involved, aimed at making contact with some of the basic underlying ideas from the literature on critical collapse. We focus on the intermediate state, which we have found appearing in cases with perturbations close to the critical limit, and examine the connection between this and the similarity solutions which play a fundamental role in the standard picture of critical collapse. We have derived a set of self-similar equations for the null-slicing form of the metric which we are using for our numerical calculations, and have then compared the results obtained by integrating these with the ones coming from our simulations for collapse of cosmological perturbations within an expanding universe. We find that the similarity solution is asymptotically approached in a region which grows to cover both the contracting matter and part of the semi-void which forms outside it. Our main interest is in the situation relevant for primordial black hole formation in the radiative era of the early universe, where the relation between the pressure $p$ and the energy density $e$ can be reasonably approximated by an expression of the form $p = we$ with $w=1/3$. However, we have also looked at other values of $w$, both because these have been considered in previous literature and also because they can be helpful for giving further insight into situations relevant for primordial black hole formation. As in our previous work, we have started our simulations with initial supra-horizon scale perturbations of a type which could have come from inflation.

description: We study the effect of baryons on the abundance of structures and substructures in a Lambda-CDM cosmology, using a pair of high resolution cosmological simulations from the GIMIC project. Both simulations use identical initial conditions, but while one contains only dark matter, the other also includes baryons. We find that gas pressure, reionisation, supernova feedback, stripping, and truncated accretion systematically reduce the total mass and the abundance of structures below ~10^12 solar masses compared to the pure dark matter simulation. Taking this into account and adopting an appropriate detection threshold lowers the abundance of observed galaxies with maximum circular velocities below 100 km/s, significantly reducing the reported discrepancy between Lambda-CDM and the measured HI velocity function of the ALFALFA survey. We also show that the stellar-to-total mass ratios of galaxies with stellar masses of ~10^5 - 10^7 solar masses inferred from abundance matching of the (sub)halo mass function to the observed galaxy mass function increase by a factor of ~2. In addition, we find that an important fraction of low-mass subhaloes are completely devoid of stars. Accounting for the presence of dark subhaloes below 10^10 solar masses further reduces the abundance of observable objects, and leads to an additional increase in the inferred stellar-to-total mass ratio by factors of 2 - 10 for galaxies in haloes of 10^9 - 10^10 solar masses. This largely reconciles the abundance matching results with the kinematics of individual dwarf galaxies in Lambda-CDM. We propose approximate corrections to the masses of objects derived from pure dark matter calculations to account for baryonic effects.

An Empirical Study of the Relationship between Lyα and UV selected Galaxies: Do Theorists and Observers `Select' the Same Objects?

description: Lyman Alpha Emitters (LAEs) are galaxies that have been selected on the basis of a strong Lyα emission line in their spectra. Observational campaigns have dramatically increased the sample of known LAEs, which now extends out to z=7. These discoveries have motivated numerous theoretical studies on the subject, which usually define LAEs in their models based on sharp Lyα luminosity and equivalent width (EW) cuts. While broadly representative, this procedure does not mimic the selection from observational programs in detail, which instead use cuts in various colour-spaces. We investigate what implications this disjoint may have for studies that aim to model LAEs. We construct an empirical model for the number density of star forming galaxies as a function of their UV and Lyα luminosity, utilising measured constraints on the luminosity functions (LFs) of drop-out galaxies, and their luminosity dependent probability distribution function of Lyα EW. In particular, we investigate whether the LAE LFs can be reproduced by defining LAEs using a (z-dependent) Lyα luminosity and EW threshold. While we are able to reproduce the observed distribution of Lyα EW among LAEs out to restframe EW 200 A, we find that our formalism over-predicts both the UV and Lyα LFs of LAEs by a factor of 2-3, and is inconsistent with observations at the ~95% level. This tension is partially resolved if we assume the Lyα EW-distribution of drop-out galaxies to be truncated at restframe EW>150 A. However the overprediction indicates that modeling LAEs with simple REW and luminosity cuts does not accurately mimic observed selection criteria, and can lead to uncertainties in the predicted number density of LAEs. On the other hand, the predicted z-evolution is not affected. We apply our formalism to drop-out galaxies at z>6, and predict the LFs of LAEs at z=7-9.

description: We study interacting bosons on a lattice in a magnetic field. When the number of flux quanta per plaquette is close to a rational fraction, the low energy physics is mapped to a multi-species continuum model: bosons in the lowest Landau level where each boson is given an internal degree of freedom, or pseudospin. We find that the interaction potential between the bosons involves terms that do not conserve pseudospin, corresponding to umklapp processes, which in some cases can also be seen as BCS-type pairing terms. We argue that in experimentally realistic regimes for bosonic atoms in optical lattices with synthetic magnetic fields, these terms are crucial for determining the nature of allowed ground states. In particular, we show numerically that certain paired wavefunctions related to the Moore-Read Pfaffian state are stabilized by these terms, whereas certain other wavefunctions can be destabilized when umklapp processes become strong.

description: Measuring nucleon-nucleon Short Range Correlations (SRC) has been a goal of the nuclear physics community for many years. They are an important part of the nuclear wavefunction, accounting for almost all of the high-momentum strength. They are closely related to the EMC effect. While their overall probability has been measured, measuring their momentum distributions is more difficult. In order to determine the best configuration for studying SRC momentum distributions, we measured the $^3$He$(e,e'pp)n$ reaction, looking at events with high momentum protons ($p_p > 0.35$ GeV/c) and a low momentum neutron ($p_n< 0.2$ GeV/c). We examined two angular configurations: either both protons emitted forward or one proton emitted forward and one backward (with respect to the momentum transfer, $\vec q$). The measured relative momentum distribution of the events with one forward and one backward proton was much closer to the calculated initial-state $pp$ relative momentum distribution, indicating that this is the preferred configuration for measuring SRC.

description: We develop a family of finite element spaces of differential forms defined on cubical meshes in any number of dimensions. The family contains elements of all polynomial degrees and all form degrees. In two dimensions, these include the serendipity finite elements and the rectangular BDM elements. In three dimensions they include a recent generalization of the serendipity spaces, and new H(curl) and H(div) finite element spaces. Spaces in the family can be combined to give finite element subcomplexes of the de Rham complex which satisfy the basic hypotheses of the finite element exterior calculus, and hence can be used for stable discretization of a variety of problems. The construction and properties of the spaces are established in a uniform manner using finite element exterior calculus.

description: Based on direct numerical simulations of forced turbulence, shear turbulence, decaying turbulence, a turbulent channel flow as well as a Kolmogorov flow with Taylor based Reynolds numbers Reλ between 69 and 295, the normalized probability density function of the length distribution P̃(l̃) of dissipation elements, the conditional mean scalar difference < Δk | l > at the extreme points as well as the scaling of the two-point velocity difference along gradient trajectories < Δun> are studied. Using the field of the instantanous turbulent kinetic energy k as a scalar, we find a good agreement between the model equation for P̃(l̃) as proposed by Wang and Peters (2008) and the results obtained in the different DNS cases. This confirms the independance of the model solution from both, the Reynolds number and the type of turbulent flow, so that it can be considered universally valid. In addition, we show a 2/3 scaling for the mean conditional scalar difference. In the second part of the paper, we examine the scaling of the conditional two-point velocity difference along gradient trajectories. In particular, we compare the linear s/τ scaling, where τ denotes an integral time scale and s the separation arclength along a gradient trajectory in the inertial range as derived by Wang (2009) with the s · a∞ scaling, where a∞ denotes the asymtotic value of the conditional mean strain rate of large dissipation elements.

description: We report on structural, magnetic and magnetocaloric properties of MnxFe1.95-xP0.50Si0.50 (x > 1.10) compounds. With increasing the Mn:Fe ratio, a first-order magneto-elastic transition gradually changes into a first-order magneto-structural transition via a second-order magnetic transition. The study also shows that thermal hysteresis can be tuned by varying the Mn:Fe ratio. Small thermal hysteresis (less than 1 K) can be obtained while maintaining a giant magnetocaloric effect. This achievement paves the way for real refrigeration applications using magnetic refrigerants.

description: We present an improved nuclear refrigerator reaching 0.3 mK, aimed at microkelvin nanoelectronic experiments, and use it to investigate metallic Coulomb blockade thermometers (CBTs) with various resistances R. The high-R devices cool to slightly lower T, consistent with better isolation from the noise environment, and exhibit electron-phonon cooling ~ T^5 and a residual heat-leak of 40 aW. In contrast, the low-R CBTs display cooling with a clearly weaker T-dependence, deviating from the electronphonon mechanism. The CBTs agree excellently with the refrigerator temperature above 20 mK and reach a minimum-T of 7.5 +/- 0.2 mK.

description: We consider the possibility of a Standard Model (SM)-like Higgs in the context of the Minimal Supersymmetric Standard Model (MSSM), with a mass of about 125 GeV and with a production times decay rate into two photons which is similar or somewhat larger than the SM one. The relatively large value of the SM-like Higgs mass demands stops in the several hundred GeV mass range with somewhat large mixing, or a large hierarchy between the two stop masses in the case that one of the two stops is light. We find that, in general, if the heaviest stop mass is smaller than a few TeV, the rate of gluon fusion production of Higgs bosons decaying into two photons tends to be somewhat suppressed with respect to the SM one in this region of parameters. However, we show that an enhancement of the photon decay rate may be obtained for light third generation sleptons with large mixing, which can be naturally obtained for large values of $\tanβ$ and sizable values of the Higgsino mass parameter.

description: We study a single two-level atom interacting with a reservoir of modes defined by a reservoir structure function with a frequency gap. Using the pseudomodes technique, we derive the main features of a trapping state formed in the weak coupling regime. Utilising different entanglement measures we show that strong correlations and entanglement between the atom and the modes are in existence when this state is formed. Furthermore, an unexpected feature for the reservoir is revealed. In the long time limit and for weak coupling the reservoir spectrum is not constant in time.

Year: 2021

description: Er ist einer der bedeutendsten Sozialhistoriker in Deutschland. Jürgen Kocka (Jg. 1941) beeinflusste die Geschichtswissenschaft seit den 1970er-Jahren maßgeblich und gilt zusammen mit Hans-Ulrich Wehler (1931-2014) als Begründer der „Bielefelder Schule“, die für eine Historische Sozialwissenschaft eintrat. Mit gerade 32 Jahren war Kocka 1973 an die nur wenige Jahre zuvor gegründete (Reform-)Universität Bielefeld berufen worden. Bis zu seiner Emeritierung im Jahr 2009 war er Professor für die Geschichte der industriellen Welt an der Freien Universität Berlin. Seit 1992 baute er als Leiter den Forschungsschwerpunkt Zeithistorische Studien in Potsdam auf, aus dem das heutige Leibniz-Zentrum für Zeithistorische Forschung Potsdam hervorging. Außerdem war er Präsident des Wissenschaftszentrums Berlin für Sozialforschung sowie Vizepräsident der Berlin-Brandenburgischen Akademie der Wissenschaften. 1975 gründete er die Zeitschrift Geschichte und Gesellschaft, die er bis 2008 mitherausgab. Für sein Wirken ist er vielfach ausgezeichnet worden, u. a. mit dem Leibniz-Preis der DFG, dem Historikerpreis der Stadt Bochum, dem Internationalen Holberg-Gedenkpreis und dem Verdienstkreuz 1. Klasse der Bundesrepublik Deutschland. Jürgen Kocka hat etliche Bücher zur Geschichte der Arbeit und der kapitalistischen Klassengesellschaft, zu Arbeitermilieu und Bürgertum usw. im 19. und 20. Jahrhundert veröffentlicht und unzählige Artikel in Sammelbänden und Fachzeitschriften verfasst. Anlässlich des Inkrafttretens der Reichsverfassung Bismarcks am 16. April 1871 sprach Yves Müller mit Jürgen Kocka über die Geschichte Preußens und des Kaiserreichs, die Demokratisierung in Deutschland, über unser Verhältnis zur Nation und aktuelle Tendenzen der Geschichtsschreibung. Das Interview bildet den Auftakt zu einem z|o-Themenschwerpunkt zur Erinnerungs- und Rezeptionsgeschichte Preußens und des Kaiserreichs, der fortlaufend ergänzt wird.

description: Despite their diverse origin, networks of large real-world systems reveal a number of common properties including small-world phenomena, scale-free degree distributions and modularity. Recently, network self-similarity as a natural outcome of the evolution of real-world systems has also attracted much attention within the physics literature. Here we investigate the scaling of density in complex networks under two classical box-covering renormalizations-network coarse-graining-and also different community-based renormalizations. The analysis on over 50 real-world networks reveals a power-law scaling of network density and size under adequate renormalization technique, yet irrespective of network type and origin. The results thus advance a recent discovery of a universal scaling of density among different real-world networks [Laurienti et al., Physica A 390 (20) (2011) 3608-3613.] and imply an existence of a scale-free density also within-among different self-similar scales of-complex real-world networks. The latter further improves the comprehension of self-similar structure in large real-world networks with several possible applications.
Hidden Supersymmetry in Dirac Fermion Quasinormal Modes of Black Holes

description: We connect the quasinormal modes corresponding to Dirac fermions in various black holes backgrounds to an N=2 supersymmetric quantum mechanics algebra, which can be constructed from the radial part of the fermionic solutions of the Dirac equation. In the massless fermion case, the quasinormal modes are in bijective correspondence with the zero modes of the fermionic system and this results to unbroken supersymmetry. The massive case is more evolved but as we prove, supersymmetry remains unbroken even in this case.

description: The DNA damage response pathways involve processes of double-strand break (DSB) repair and cell cycle checkpoint control to prevent or limit entry into S phase or mitosis in the presence of unrepaired damage. Checkpoints can function to permanently remove damaged cells from the actively proliferating population but can also halt the cell cycle temporarily to provide time for the repair of DSBs. Although efficient in their ability to limit genomic instability, checkpoints are not foolproof but carry inherent limitations. Recent work has demonstrated that the G1/S checkpoint is slowly activated and allows cells to enter S phase in the presence of unrepaired DSBs for about 4–6 h post irradiation. During this time, only a slowing but not abolition of S-phase entry is observed. The G2/M checkpoint, in contrast, is quickly activated but only responds to a level of 10–20 DSBs such that cells with a low number of DSBs do not initiate the checkpoint or terminate arrest before repair is complete. Here, we discuss the limitations of these checkpoints in the context of the current knowledge of the factors involved. We suggest that the time needed to fully activate G1/S arrest reflects the existence of a restriction point in G1-phase progression. This point has previously been defined as the point when mitogen starvation fails to prevent cells from entering S phase. However, cells that passed the restriction point can respond to DSBs, albeit with reduced efficiency.

description: It has long been assumed in physics that for information to travel between two parties in empty space, "Alice" and "Bob", physical particles have to travel between them. Here, using the "chained" quantum Zeno effect, we show how, in the ideal asymptotic limit, information can be transferred between Alice and Bob without any physical particles traveling between them.

description: In this paper we show how a gravitational field generated by a given energy-momentum distribution (for all realistic cases) can be represented by distinct geometrical structures (Lorentzian, teleparallel and non null nonmetricity spacetimes) or that we even can dispense all those geometrical structures and simply represent the gravitational field as a field, in the Faraday's sense, living in Minkowski spacetime. The explicit Lagrangian density for this theory is given and the field equations (which are a set of four Maxwell's like equations) are shown to be equivalent to Einstein's equations. We also analyze if the teleparallel formulation can give a mathematical meaning to "Einstein's most happy thought", i.e. the equivalence principle. Moreover we discuss the Hamiltonian formalism for for our theory and its relation to one of the possibles concepts for energy of the gravitational field which emerges from it and the concept of ADM energy. One of the main results of the paper is the identification in our theory of a legitimate energy-mometum tensor for the gravitational field expressible through a really nice formula.
