The genus Leucosporidium in Southern British Columbia, an area of temperate climate
Creators: name: Summerbell, Richard Charles
Publisher: name: University of British Columbia
Year: 2010

description: A search for members of the genus Leucospor idium (Ustilaginaceae) in and near southern British Columbia has yielded 147 isolates of L. scottii, and a single isolate of an undescribed species with apparent affinities in the genus. L. scottii was primarily found on decaying marine vegetation and driftwood, but isolates were also obtained from stream foam, snow, a decaying turnip root, bark mulch, and rain-derived stem flow over the trunk of a living tree. The species predominated in laboratory incubations of marine algal materials collected in the winter, spring, and late autumn. The majority of isolates obtained directly from natural substrates were also found during periods of cold seasonal conditions. It is suggested that low temperature is characteristic of L. scottii habitats. Locally-obtained L. scottii strains are all heterothallic, and are completely interfertile with mating test strains originating from the southern hemisphere. Morphological and known physiological and biochemical characters of the local strains are similar to those previously described for the species. However, mating studies of local isolates have revealed that the tetrapolar incompatibility system of L. scottii is distinguished by the possession of multiple alleles at the A locus. Similar modifications of the tetrapolar system are known in Tremella and other heterobasidiomycete genera, but have not previously been reported in species of the Leucosporidium-Rhodosporidium group. The strain thought to belong to an undescribed species of Leucosporidium was obtained from a sample of filamentous green algae growing in a vernal pond near a peat bog. The fungus is homothallic, and is morphologically and physiologically distinct from other Leucosporidium and Rhodosporidium species. Of the six known species of Leucosporidium, five (L. antarcticum, L. friqidum, L. gelidum, L. nivalis, and L. stokesii) were not found during the course of the present study. All five species are obligately psychrophilic and may not be able to remain established within the study area. However, a survey of local L. scottii isolates showed that 5 out of 147 isolates (3.4%) were obligately psychrophilic.

description: Eastern Uttar Pradesh comprising of 27 districts is less industrialised andunderdeveloped due to fewer number of industries and established MSMEsin the region. This case study illustrates the huge potential for developmentof new MSME sector like furniture industry, paper and paper product industryand fruit processing units in the region. For present case study the easternUttar Pradesh has been divided into 3 regions viz. Tarai region, Ganga-Ghaghradoab region and Vindhyan upland. The Ganga-Ghaghra doab region hasmaximum wood and agro-based micro, small and medium enterprises i.e.21358 units followed by Tarai region and Vindhya region having 11548 unitsand 2287 units respectively. Average number of wood based micro and smallenterprises and artisan units is minimum for Vindhyan region i.e. 726.33 andmaximum for Ganga-Ghaghra Doab i.e.1642.92. The share of eastern UP inwood based industries is only 6.59%. The study reflects that MSMEs can beboon and a hope for economy of the region in near future and establishmentof timber/furniture industry in Gorakhpur and paper manufacturing unit inSonebhadra district will result in overall development of the state.

description:
Low band-gap conjugated polyelectrolytes (CPEs) can serve as efficient chromophores for use on photoelectrodes for dye-sensitized photoelectrochemical cells. Herein is reported a novel CPE based on poly­(isoindigo-co-thiophene) with pendant sodium butylsulfonate groups (PiIT) and its use in construction of layer-by-layer (LbL) chromophore–catalyst assemblies with a Pt-based H+ reduction catalyst (PAA-Pt) for water reduction. A novel Stille polymerization/postpolymerization ion-exchange strategy was used to convert an organic-soluble CPE to the water-soluble poly­(isoindigo-co-thiophene). The anionic PiIT polyelectrolyte- and polyacrylate-stabilized Pt-nanoparticles (PAA-Pt) were codeposited with cationic poly­(diallyldimethylammonium) chloride (PDDA) onto inverse opal (IO), nanostructured indium tin oxide film (nITO) (IO nITO) atop fluorine doped tin oxide (FTO), by using LbL self-assembly. To evaluate the performance of novel conjugated PiIT//PAA-Pt chromphore–catalyst assemblies, interassembly hole transfer was investigated by photocurrent density measurements on FTO//IO nITO electrodes. Enhanced cathodic photocurrent is observed for the polychromophore–catalyst assemblies, compared to electrodes modified with only PiIT, pointing toward photoinduced hole transfer from the excited PilT to the IO nITO. Prolonged photoelectrolysis experiments reveal H2 production with a Faradaic yield of approximately 45%. This work provides new routes to carry out visible-light-driven water reduction using photocathode assemblies based on low band-gap CPEs.

description: We report the near-edge x-ray absorption fine structure (NEXAFS) spectrum of a single layer of graphite (graphene) obtained by micromechanical cleavage of Highly Ordered Pyrolytic Graphite (HOPG) on a SiO2 substrate. We utilized a PhotoEmission Electron Microscope (PEEM) to separately study single- double- and few-layers graphene (FLG) samples. In single-layer graphene we observe a splitting of the pi* resonance and a clear signature of the predicted interlayer state. The NEXAFS data illustrate the rapid evolution of the electronic structure with the increased number of layers.

become established in scientific competition. Researchers seek status, which
they get if their results are used by the next generation. Quality is hereditary
in the sense that input quality affects output quality. Hereditary quality

description: We derive a material-realistic real-space many-body Hamiltonian for twisted bilayer graphene from first principles, including both single-particle hopping terms for $p_z$ electrons and long-range Coulomb interactions. By disentangling low- and high-energy subspaces of the electronic dispersion, we are able to utilize state-of-the-art constrained Random Phase Approximation calculations to reliably describe the non-local background screening from the high-energy $s$, $p_x$, and $p_y$ electron states for arbitrary twist angles. The twist-dependent low-energy screening from $p_z$ states is subsequently added to obtain a full screening model. We use this approach to study real-space plasmonic patterns in electron-doped twisted bilayer graphene supercells and find, next to classical dipole-like modes, also twist-angle-dependent plasmonic quantum-dot-like excitations with $s$ and $p$ symmetries. Based on their inter-layer charge modulations and their footprints in the electron energy loss spectrum, we can classify these modes into "bright" and "dark" states, which show different dependencies on the twist angle.

description: It is often conjectured that participatory decision making may increase
acceptance even of unfavorable decisions. The present paper tests this conjecture
in a three-person power-to-take game. Two takers decide which fraction
of the responder's endowment to transfer to themselves; the responder
decides which part of the endowment to destroy. Thus, the responder can
punish greedy takers, but only at a cost to herself. We modify the game by
letting the responder participate in takers' transfer decision and consider the
e�ect of participation on the destruction rate. We �nd that participation
matters. Responders destroy more if they (1) had no opportunity to participate
in the decision making process and (2) are confronted with highly
unfavorable outcomes. This participation e�ect is highly signi�cant for those
responders (the majority) who show negative reciprocity (i.e., destroy more
when takers are greedier).

description: Die Rolle der europäischen Wettbewerbspolitik in Medienmärkten bleibt eine
ambivalente. Es steht dabei außer Zweifel, dass es der europäischen Wettbewerbspolitik
vorrangig um den Schutz des ökonomischen Wettbewerbs geht. In den
Kommunikationen der Wettbewerbsdirektion innerhalb der Europäischen Kommission
wurde im Laufe der 1990er Jahre freilich auch immer wieder betont, dass die
Dimension Vielfalt in Medienmärkten in besonderer und gegenüber ‚normalen’
Gütermärkten in stärkerer Weise schützenswert sei. Das Wettbewerbselement
Medienpluralismus (Meinungsvielfalt, kulturelle Vielfalt) wird damit als
medienspezifische Besonderheit betont, was bei vielen Autoren die Erwartung geweckt
hat, dass diese Wettbewerbsdimension ergänzend zu den allgemeinen, nichtmedienspezifischen
ökonomischen Betrachtungen Berücksichtigung findet. In jüngerer
Zeit scheint dies aber in der Fallpraxis der Kommission nicht (mehr) zu geschehen. So
spielte Meinungsvielfalt im Telepiu-Fall im Gegensatz zu früheren Pay-TV-Fällen keine
erkennbare Rolle (Abschnitt 3.2.). Darüber hinaus kann mit Blick auf kulturelle Vielfalt
anhand der Musikmärkte vielmehr eine abnehmende Bedeutung vielfaltsrelevanter
Wettbewerbselemente in der europäischen Fusionskontrolle konstatiert werden
(Abschnitt 3.3.).
Bezüglich der Frage, ob Medienpluralismus ein zusätzliches Argument der
Wettbewerbspolitik darstellen sollte oder ob der Schutz des ökonomischen Wettbewerbs
eine hinreichende Bedingung für Medienvielfalt darstellt, weist die Medienökonomik
kein klares Bild auf (Abschnitt 2.2.). Hier sind weitere Forschungsanstrengungen
dringend notwendig, um die komplizierte Interaktion von Marktwettbewerb und
Meinungs- bzw. kultureller Vielfalt in Medienmärkten besser zu verstehen und genauer
analysieren zu können. Allerdings zeigt sich recht deutlich, dass die speziellen
Funktionsweisen des Wettbewerbs auf Medienmärkten auch theoretisch relevant sind
und aus ökonomischer Perspektive eine distinkte und spezielle Analyse der
Wettbewerbsverhältnisse erfordern. Es erscheint aus wirtschaftswissenschaftlicher Sicht
unangemessen, die Erkenntnisse hinsichtlich ‚normaler’ Gütermärkte einfach zu
übertragen. Trotz des proklamierten more economic approach werden die spezifischen
medienökonomischen Erkenntnisse von der Kommission bei der Analyse des
Wettbewerbs auf Medienmärkten bisher nicht hinreichend angewendet.

description: We investigate the intermediate-age asymptotic giant branch stellar population of two Local Group dwarf irregular galaxies to characterize their carbon star population in near-infrared (IR). Our work is based on J and K-band SOFI near-IR photometry complemented with optical ground based and HST photometry. We show that near-IR photometry is a very powerful tool for carbon star detection. We recovered two out of three previously-known carbon stars in DDO 210 and discovered six additional objects in this galaxy which have optical and near-IR colors consistent with carbon giants. This brings the total number of bona-fide C-star candidates in DDO 210 to nine. We detected a large population of C-star candidates in SagDIG, 18 of which were previously identified in Demers & Battinelli (2002) and Cook (1987), and six new bona-fide carbon stars. We present their optical and near-IR colors and use their luminosity function to put constraints on the star formation history (SFH) in this dwarf irregular galaxy.

description: During the survey phase of the Kepler mission, several thousands of stars were observed in short cadence, allowing the detection of solar-like oscillations in more than 500 main-sequence and sub-giant stars. Later, the Kepler Science Office discovered an issue in the calibration that affected half of the short-cadence data, leading to a new data release (DR25) with improved corrections. We re-analyze the one-month time series of the Kepler survey phase to search for new solar-like oscillations. We study the seismic parameters of 99 stars (46 targets with new reported solar-like oscillations) increasing by around 8% the known sample of solar-like stars with asteroseismic analysis of the short-cadence data from Kepler. We compute the masses and radii using seismic scaling relations and find that this new sample populates the massive stars (above 1.2Ms and up to 2Ms) and subgiant phase. We determine the granulation parameters and amplitude of the modes, which agree with previously derived scaling relations. The stars studied here are slightly fainter than the previously known sample of main-sequence and subgiants with asteroseismic detections. We also study the surface rotation and magnetic activity levels of those stars. Our sample of has similar levels of activity compared to the previously known sample and in the same range as the Sun between the minimum and maximum of its activity cycle. We find that for 7 stars, a possible blend could be the reason for the previous non detection. We compare the radii obtained from the scaling relations with the Gaia ones and find that the Gaia radii are overestimated by 4.4% on average compared to the seismic radii and a decreasing trend with evolutionary stage. We re-analyze the DR25 of the main-sequence and sub-giant stars with solar-like oscillations previously detected and provide their global seismic parameters for a total of 526 stars.

description: Does popular support for democratic backsliding, or autocratization, have a religious basis? This article addresses this question by investigating the relationship between Buddhist religiosity and voter support for the successor parties of the National Council for Peace and Order (NCPO), the military junta that ruled Thailand between 2014 and 2019. Relying on data from a survey conducted following the 14 May 2023 election, we find that certain Buddhist beliefs, practices, and sectarian affinities correlate with backing for the NCPO’s successor parties in both the 2019 and 2023 elections. Ceteris paribus, authoritarian successor parties find greater support than their main pro-democratic rivals among voters with stronger beliefs in reincarnation and the law of karma; who are less orientated towards sacred Buddhist objects; who engage in Vipassana meditation more frequently; and who feel closer to one new Buddhist movement (Santi Asoke) and more distant to another (Wat Phra Dhammakaya). Taken together, these findings demonstrate that the main electoral cleavage in Thailand’s 2019 and 2023 elections – that between authoritarian successor parties and their main pro-democratic rivals – reflects important differences in Buddhist religiosity heretofore ignored in explaining Thailand’s political divide.

description: Advances in competition economics as well as in computational and empirical
methods have offered the scope for the employment of merger simulation models in merger
control procedures during the past almost 15 years. Merger simulation is, nevertheless, still a
very young and innovative instrument of antitrust and, therefore, its ‘technical’ potential is far
from being comprehensively exploited and teething problems in its practical use in the
antitrust environment prevail. We provide a classification of state-of-the-art merger
simulation models and review their previous employment in merger cases as well as the
problems and limitations currently associated with their use in merger control. In summary,
merger simulation models represent an important and valuable extension of the toolbox of
merger policy. However, they do not qualify as a magic bullet and must be combined with
other, more traditional instruments of competition policy in order to comprehensively unfold
its beneficial effects.

We find, first, that central bank communication moves financial markets in the intended direction. In particular, shorter maturities are affected in an economically meaningful way. Second, speeches by the Chairman generate relatively more public attention than communication by other governors or presidents. Finally, central bank communication is even more market relevant during the financial crisis subsample.

description: We compute the precise elementary/composite field content of mass eigenstates in holographic duals of warped models in a slice of AdS_5. This is accomplished by decomposing the bulk fields not in the usual Kaluza-Klein basis, but rather into a holographic basis of 4D fields, corresponding to purely elementary source or CFT composite fields. Generically, this decomposition yields kinetic and mass mixing between the elementary and composite sectors of the holographic theory. Depending on where the bulk zero mode is localized, the elementary/composite content may differ radically, which we show explicitly for several examples including the bulk Randall-Sundrum graviton, bulk gauge boson, and Higgs boson.

description: This paper reports on a set of trust games with third party punishment (TPP) where
participants are either family members or friends or unrelated villagers. The experimental
sessions were carried out in southern Namibia (Karas) and the bordering northern South
Africa (Namaqualand). The aim was to test several hypotheses derived from kin selection
theory as well as to assess the importance of third party punishment for encounters among
family members and friends. Building on Hamilton, (1964) it was proposed by e.g. Madsen et
al., (2007) that kinship is the baseline behaviour among humans. Thus, I use kinship as basis
for comparison of how we treat friends and unrelated people and when there is the possibility
to punish free-riding behaviour. It turns out that kinship is the baseline behaviour when no
other features are available to humans. However, a personal exchange among friends that has
a third party observer performs better than a personal exchange among family members
without third party punishment. Contributions to family members can substantially be
increased by third party punishment. Thus, human ability to sustain a norm by punishing freeriders
at personal costs could also have played an important role in sustaining co-operation
among kin.

description: We polarize nuclear spins in a GaAs double quantum dot by controlling two-electron spin states near the anti-crossing of the singlet (S) and m_S=+1 triplet (T+) using pulsed gates. An initialized S state is cyclically brought into resonance with the T+ state, where hyperfine fields drive rapid rotations between S and T+, 'flipping' an electron spin and 'flopping' a nuclear spin. The resulting Overhauser field approaches 80 mT, in agreement with a simple rate-equation model. A self-limiting pulse sequence is developed that allows the steady-state nuclear polarization to be set using a gate voltage.

description: In this paper, the mechanism of fault pressurization in rapid slip events is analyzed on the basis of a complete characterization of the thermo-poro-mechanical behavior of a clayey gouge extracted at 760m depth in Aigion fault in the active seismic zone of the Gulf of Corinth, Greece. It is shown that the thermally collapsible character of this clayey gouge can be responsible for a dramatic reduction of effective stress and a full fluidization of the material. The thickness of the 'ultra localized' zone of highly strained material is a key parameter that controls the competing phenomena of pore pressure increase leading to fluidization of the fault gouge and temperature increase leading to pore fluid vaporization.

description: Successful lac cultivation depends on efficient and proper use of lac host plants. Lac insects can survive on more than 400 plant species but only about two dozen host plants are utilized for lac production because commercial lac cultivation has not been found economically viable on many plants and systematic lac cultivation has not been attempted on several hosts species in regions not traditionally lac strongholds. The revenue generation opportunities may be enhanced through expansion of lac culture with efficient utilization of available host plants all over the country. With the view investigation was carried out to record natural infestation of lac insect on Calliandra surinamensis and its use as source of brood lac for inoculation on other lac host species in Prayagraj district of eastern Uttar Pradesh, India. The findings reveal that C. surinamensis holds promise for large scale lac cultivation in eastern UP as it supports substantial populations of lac insect in great density indicative of excellent establishment and survival. The study recommends integration of lac culture with agriculture including C. surinamensis diversifying the land use for optimizing productivity.

description: This study is the first of a series of papers that provide a technique to analyse the mixed-modes frequency spectra and characterise the structure of stars on the subgiant and red-giant branches. We define seismic indicators, relevant of the stellar structure and study their evolution on a grid of models. The proposed method, EGGMiMoSA, relies on the asymptotic description of mixed modes, defines initial guesses for the parameters, and uses a Levenberg-Marquardt technique to adjust the mixed-modes pattern efficiently. We follow the evolution of the mixed-modes parameters along a grid of models from the subgiant phase to the RGB bump and extend past works. We show the impact of the mass and composition on their evolution. The evolution of the period spacing $Δπ_1$, pressure offset $ε_p$, gravity offset $ε_g$, and coupling factor $q$ as a function of $Δν$ is little affected by the chemical composition and it follows two different regimes depending on the evolutionary stage. On the subgiant branch, the models display a moderate core-envelope density contrast. The evolution of $Δπ_1$, $ε_p$, $ε_g$, and $q$ thus significantly changes with the mass. Also, we demonstrate that, at fixed Z/X and with proper measurements of $Δπ_1$ and $Δν$, we may unambiguously constrain the mass, radius and age of a subgiant star. Conversely, on the red-giant branch, the core-envelope density contrast becomes very large. Consequently, the evolution of $ε_p$, $ε_g$ and $q$ as a function of $Δν$ becomes independent of the mass. This is also true for $Δπ_1$ in stars with masses $\lesssim 1.8M_\odot$ because of core electron degeneracy. This degeneracy is lifted for higher masses, again allowing for a precise measurement of the age. Overall, our computations qualitatively agree with past observed and theoretical studies.

description: Successful lac cultivation depends on efficient and proper use of lac host plants. Lac insects can survive on more than 400 plant species but only about two dozen host plants are utilized for lac production because commercial lac cultivation has not been found economically viable on many plants and systematic lac cultivation has not been attempted on several hosts species in regions not traditionally lac strongholds. The revenue generation opportunities may be enhanced through expansion of lac culture with efficient utilization of available host plants all over the country. With the view investigation was carried out to record natural infestation of lac insect on Calliandra surinamensis and its use as source of brood lac for inoculation on other lac host species in Prayagraj district of eastern Uttar Pradesh, India. The findings reveal that C. surinamensis holds promise for large scale lac cultivation in eastern UP as it supports substantial populations of lac insect in great density indicative of excellent establishment and survival. The study recommends integration of lac culture with agriculture including C. surinamensis diversifying the land use for optimizing productivity.

description: Die Lohnkurve untersucht den Zusammenhang zwischen dem Lohnniveau und der Arbeitslosigkeit
auf regionaler Ebene. Zu ihr gibt es eine Vielzahl von empirischen Untersuchungen.
Die nachstehenden Ergebnisse modifizieren und ergänzen diese Arbeiten am Beispiel der
Lohnkurve in Deutschland in mehrfacher Hinsicht:
- Die Ergebnisse im Rahmen der empirischen Regionalforschung reagieren äußerst sensibel
auf die Abgrenzung regionaler Untersuchungseinheiten. Hier werden regionale
Arbeitsmärkte genutzt, die als räumliche Verwertungsbereiche des Produktionsfaktors
Arbeit unverzerrte Ergebnisse liefern.
- Durch Schätzung räumlicher Preisindizes ist es möglich, im Schätzansatz Nominaldurch
die eigentlich ökonomisch relevanten Reallöhne zu ersetzen.
- In der modernen räumlichen Ökonometrie werden Abhängigkeiten zwischen den regionalen
Untersuchungseinheiten berücksichtigt, so auch in den nachstehenden Ergebnissen.
- Die Lohnkurve muss nicht in allen Regionen gleich sein. Vielmehr ist es plausibler,
dass sich aufgrund von Besonderheiten der Arbeitsmärkte in den Regionen die Koeffizienten
des Schätzansatzes interregional voneinander unterscheiden. Die Hypothese
wird überprüft und im Schätzansatz berücksichtigt.
Diese Erweiterungen der Lohnkurve führen zu Schätzergebnissen, die die bisherigen Aussagen
zur Lohnkurve erheblich ändern.

The nutritional status and physical work performance of children of migrant agricultural workers in Southern Brazil
Creators: name: Waddell, Charlotte
Publisher: name: University of British Columbia
Year: 2010

description: A study was conducted to investigate and compare the nutritional status and physical work performance of children of Brazilian migrant agricultural workers with Brazilian children from wel1-to-do backgrounds. The relationship between nutritional status and physical work performance was also investigated. Dietary analysis was conducted using the 24-hour diet recall method. Evidence was found that intakes of energy, calcium, thiamin, riboflavin, niacin, and vitamin C may have been inadequate among migrant worker children. Their diet was generally monotonous and consisted mainly of rice, beans, and coffee with sugar. Diets of well-to-do children were considerably more varied with good representation from all major food groups. Anthropometric assessment indicated that migrant worker children had values for weight and triceps skinfold thickness that were low compared to American standards. Values for height, arm circumference, and arm muscle circumference were average compared to American standards. Well-to-do children exceeded American standards for all anthropometric parameters measured. Biochemical investigations of protein and iron status were also conducted. Serum total protein and albumin levels were normal in most subjects in both groups. However, many migrant worker, children had low values for hematocrit, serum iron, and transferrin saturation. Most well-to-do children had normal values for these parameters. Hemoglobin levels were adequate in most subjects. Physical work performance was found to be impaired in migrant worker children. Exercise heart rates and post-exercise blood lactic acid levels in response to a standardized bicycle-ergometer work test were significantly higher in migrant worker compared to wel1-to-do children. In addition, a significant correlation was found between anthropometric indicators of nutritional status and parameters of physical work performance. Finally, socio-economic and ecological assessment indicated that the living conditions of migrant worker children were impoverished and unsanitary. This probably aggravated health problems such as infections that were found to occur among these children. Well-to-do children did not share these conditions.
Finite element analysis of the indentation test on rocks with microstructure

description: Strength parameters of rocks are currently determined from indentation tests. In this paper, a finite element analysis of this test is presented and scale effect is studied. The rock is modelled as an elasto-plastic medium with Cosserat microstructure and consequently possesses an internal length. The response of the indentation curve is studied for various values of the size of the indentor as compared to the internal length of the rock in order to assess the scale effect.

description: Die häufigsten Erkrankungen in entwickelten Ländern sind Herz- Kreislaufkrankheiten, Tumorleiden, Stoffwechsel-, Autoimmun- und psychiatrische Erkrankungen. Diese werden als komplexe Krankheiten bezeichnet, da ihre Entstehung sowohl von genetischen als auch von nicht genetischen, von außen einwirkenden Faktoren beeinflusst wird. Viele dieser Krankheiten zeigen deutliche Unterschiede zwischen Männern und Frauen sowohl im Hinblick auf die Neuerkrankungsrate als auch auf den Krankheitsverlauf. Als Erklärungen werden Unterschiede in den soziokulturellen Rollen von Männern und Frauen und daraus resultierend die Exposition gegenüber unterschiedlichen Risikofaktoren diskutiert. Kürzlich fand man durch genetische Studien für einige Krankheiten Hinweise auf unterschiedliche prädisponierende Gene bei Männern und Frauen. Diese Gene entwickeln ihre Wirkung auf die Krankheit nur auf dem Hintergrund eines Geschlechts. Geschlechterabhängige Präventions- und Therapiemaßnahmen für diese Erkrankungen erscheinen notwendig. Dieser Beitrag beschäftigt sich mit den genetischen Aspekten des geschlechterabhängigen Erkrankungsrisikos. Wir schildern Beispiele für geschlechtsspezifische Assoziationen sowohl beim Menschen als auch im Tierversuch und diskutieren methodische Probleme sowie mögliche biologische Mechanismen.

description: Despite still being younger than a decade, the theory of multisided market has
offered numerous valuable insights for the analysis of non-ordinary industries in which a
supplier serves two distinct customer groups that are indirectly interrelated by externalities.
Examples include payment systems, matching agencies, commercial media and software
platforms. However, professional sports markets have largely been neglected so far in this
kind of research although they possess the characteristics of multisided markets. We
contribute to filling this gap by describing the platform elements of professional suppliers of
sports events and outlining problems where an application of this theoretical framework is
likely to provide valuable insights and to add to the existing knowledge. Among these
problems are integrative pricing strategies of sports clubs towards such different customer
groups like attendees, broadcasters, sponsors, etc., including their welfare and antitrust
implications, design decisions of sports associations in order to promote positive feedback
loops among the customer groups as well as strategies to reinforce positive externalities
among customer groups and alleviate negative ones.

description: On the basis of dissected cadavers archaeologically recorded from 40 sites in German- and English-speaking countries, this article examines the economic processes of corpses in the area of conflict between supply, demand and distribution in the 18th/19th centuries. I will answer questions about the recognition of corresponding finds as well as their locations, about the actors involved and their networks. The focus is also on the costs associated with individual work steps in anatomy and how these affected the handling of the dead. It can be postulated that the mode of burial of anatomy cadavers reflects both monetary and social aspects directly related to a form of objectification.

description: Die ältere Bremer Forschung zur frühstädtischen Entwicklung hängt einigen paradigmatischen Ansichten nach. Dies geschieht teils unterbewusst, teils im Bemühen um eine Bedeutung des eigenen Forschungsgegenstandes. Befördert werden sie durch einen Mangel an schriftlichen, archäologischen, aber durchaus auch geologischen Quellen. Der Gründungsmythos um Karl dem Großen schwebt nach wie vor über allem. In der Frühmittelalterforschung über die Etablierung der sächsischen Bistümer und Klöster wurde zuletzt ein Paradigmenwechsel eingeleitet, den sich auch andere Disziplinen zum Vorbild nehmen können. Der Beitrag skizziert aus diesem Bewusstsein heraus die frühstädtische Entwicklung Bremens einschließlich seines Hafens.

description: We show in a dynamic investment setting whether firms choose FDI
or international portfolio investment (FPI) in the presence of stochastic
productivity taking into account di¤erences in flexibility of both invest-
ments. Isolated FPI and FDI investments are compared to combined FPI
and FDI investments. FDI requires higher investment specific costs than
FPI. Thus, it is not possible to adjust FDI to environmental changes every
period. In contrast, FPI bears lower fixed costs and can be adjusted im-
mediately to short-term changes in the environment. Additionally, as a
result of the investors control position FDI yields a higher return than
FPI. Hence, there is a trade-off between flexibility and higher return for
firms deciding between FDI and FPI.We explore whether as a consequence
of higher investment specific fixed costs and lower flexibility in the case
of FDI, small firms prefer FPI and larger firms invest in FDI. We show
that a combined strategy dominates the isolated strategy always in times.
Further, combined international investment comprises a higher incentive
for firms to invest in r&d-investment and consequently firm productivity
increase faster than with isolated international investment. Depending on
the success-probability and the correlation between the various investment
possibilities, even small firms (low productivity) invest in FDI.
