Reactions to group devaluation and social inequity: A comparison of social identity and system justification predictions.
Creators: name: Rubin, Mark
Publisher: name: Figshare
Year: 2016
Subjects: Personality, Social and Criminal Psychology

description: System justification theory (SJT) proposes that support for
social inequality should be stronger among members of devalued groups than
among members of higher status groups; that embracing the system in this way
soothes anger and leads to a withdrawal of support for social change; and that
these effects should occur when group interest is weak. We compared these SJT
predictions with identity management and hope for group advancement accounts
that we deduced from social identity theory (SIT) which suggest that both system
justification and support for social change will be significant when group interest
is strong. Consistent with the SIT-based accounts, Study 1 (N = 116, Malaysia, M
age = 19.09 years) showed that strong identifiers were more concerned about
their in-group’s reputation than weak identifiers, and that this concern
increased system justification but only before an out-group audience to whom a
need to present one’s group in good light is normally strong. Study 2 (N = 375,
Australia, M age = 23.59 years) conceptually replicated Study 1’s results and
further revealed that strong identifiers justified the system due to the hope
that their in-group status would improve in the future. Finally, Study 3 (N =
132, Germany, M age = 20.34 years) revealed that system justification soothed
anger and reduced support for social protest but only when group interest was
strong (not weak). We did not find evidence in support of SJT predictions.

description: Diversos estudos realizados nos últimos anos revelaram que os hábitos de audição de música seguem determinados padrões ao longo do tempo, tais como a preferência por ouvir determinados artistas ou géneros musicais em certos períodos do dia e em determinados dias da semana. Porém, apenas recentemente têm surgido algoritmos de recomendação que tiram partido deste conhecimento para melhorar as recomendações. Uma das abordagens mais estudada e utilizada em produtos comercias é a de Filtros Colaborativos, que se foca nas músicas ouvidas por utilizadores com gostos semelhantes, mas que deixa de fora o contexto temporal em que estas foram ouvidas. Neste trabalho, apresentamos uma análise da utilização de informação temporal em técnicas de filtros colaborativos baseadas em sessões. De forma a medir a importância do contexto temporal na recomendação, comparámos dois algoritmos: um algoritmo base, sem recurso a informação temporal; e um algoritmo que tira partido de características temporais das sessões. Estas características são usadas pelo algoritmo para inferir similaridade entre as sessões. Para avaliar os dois algoritmos em termos de precisão e ordenação das recomendações, medimos o HitRatio e Mean Reciprocal Rank. Os resultados evidenciam que a inclusão de características temporais neste tipo de algoritmos é benéfica para melhorar a precisão, mas não a ordenação das listas de recomendações geradas.

description: The recently measured charge asymmetry of like-sign dimuon events by the D0 collaboration at Tevatron shows the 3.9 σ deviation from the standard model prediction. In order to solve this mismatch, we investigate the right-handed current contributions to $B_s-\bar{B}_s$ and $B_d-\bar{B}_d$ mixings which are the major source of the like-sign dimuon events in $b \bar{b}$ production in general left-right models without imposing manifest or pseudo-manifest left-right symmetry. We find the allowed region of new physics parameters satisfying the current experimental data.

The measures under consideration include alternatives that would allow an electronic monitoring (EM) system to supplement existing observer coverage. The purpose of this action is to advance cost efficiency and compliance monitoring through improved salmon accounting and reduced monitoring costs.
Soil microbial community responses to green-tree retention harvesting in coastal British Columbia
Creators: name: Dewi, Meiliana
Publisher: name: University of British Columbia
Year: 2009

description: Green-tree or variable retention harvesting is being increasingly adopted as an alternative to clearcutting in the Pacific Northwest, including British Columbia (BC), to maintain forest biodiversity and function and enhance aesthetic quality. Green-tree retention may also benefit the soil resource, and research is needed to understand how these silvicultural treatments affect soil nutrient availability and microbial community structure and function. The objectives of this study were to determine: (i) whether green-tree retention harvesting is better than clearcutting to retain nutrient availability and the structural and functional characteristics of the soil microbial community, and (ii) which spatial pattern of green-tree retention is superior for this purpose. Using an adjacent uncut forest to provide a baseline comparison, nutrient availability, substrate-induced respiration (SIR), enzyme activities, and phospholipid fatty acids (PLFA) were analysed in the forest floor and mineral soil of a second-growth Douglas-fir and western hemlock forest at the Silviculture Treatments for Ecosystem Management in the Sayward (STEMS) trial near Campbell River on Vancouver Island, BC, five years after aggregated retention harvesting, dispersed retention harvesting, and clearcutting. In general, there was no indication that nutrient availability and the structure and function of the soil microbial community in either green-tree retention treatment was intermediate between the clearcut and the uncut forest. Harvesting had no significant effect on nitrate and phosphate availabilities and SIR rates, but it generally reduced ammonium availability and enzyme activities in the forest floor. Green-tree retention harvesting caused a shift in the structure of soil microbial community, whereas clearcutting did not. Green-tree retention harvesting appeared better than clearcutting in maintaining the activities of forest floor β-glucosidase, N-acetyl-glucosaminidase, and peroxidase enzymes closer to the level found in the uncut forest, but did not offer advantages over clearcutting in maintaining soil microbial community structure. Comparing the two spatial patterns of green-tree retention, the dispersed retention treatment was superior to the aggregated retention treatment because of its ability to retain soil microbial community structure and function more evenly across the harvested site.

description: Advancements in infrared IR open up the possibility to spatially resolve AGN on the parsec-scale level and study the circumnuclear dust distribution, commonly referred to as the "dust torus", that is held responsible for the type 1/type 2 dichotomy of AGN. We used the mid-IR beam combiner MIDI together with the 8m telescopes at the VLTI to observe the nucleus of the Seyfert 2 galaxy NGC 424, achieving an almost complete coverage of the uv-plane accessible by the available telescope configurations. We detect extended mid-IR emission with a relatively baseline- and model-independent mid-IR half-light radius of (2.0 \pm 0.2) pc \times (1.5 \pm 0.3) pc (averaged over the 8-13 μm wavelength range). The extended mid-IR source shows an increasing size with wavelength. The orientation of the major axis in position angle -27deg is closely aligned with the system axis as set by optical polarization observations. Torus models typically favor extension along the mid-plane at mid-IR wavelengths instead. Therefore, we conclude that the majority of the pc-scale mid-IR emission (>~60%) in this type 2 AGN originates from optically-thin dust in the polar region of the AGN, a scenario consistent with the near- to far-IR SED. We suggest that a radiatively-driven dusty wind, possibly launched in a puffed-up region of the inner hot part of the torus, is responsible for the polar dust. In this picture, the torus dominates the near-IR emission up to about 5 μm, while the polar dust is the main contributor to the mid-IR flux. Our results of NGC 424 are consistent with recent observations of the AGN in the Circinus galaxy and resemble large-scale characteristics of other objects. If our results reflect a general property of the AGN population, the current paradigm for interpreting and modeling the IR emission of AGN have to be revised. (abridged)

description: A medida que, no nosso dia-a-dia, vamos coleccionando cada vez mais fotografias vamos explorando-as cada vez menos, perdendo a visão holística da cor, bem como uma possível relação com o resto da nossa informação pessoal. Todos temos camaras digitais e smartphones com os quais tiramos imensas fotografias e, por vezes, é difícil organizar e gerir tanta informação, em especial quando queremos encontrar alguma foto. As cores predominantes da foto e a relação da data da foto com o PIM (Personal Information Management) podem ser uma solução para este problema. Com este artigo pretende-se apresentar o Colorfül, uma forma diferente e inovadora de um utilizador olhar para o seu álbum de fotografias e de as relacionar pela cor e com outra informação pessoal, como os assuntos de email e os eventos de calendário, interagindo com esta, explorando as suas características mais peculiares e encontrando padrões que, `a partida, não seriam visíveis. Neste artigo apresentamos, também, resultados de testes com utilizadores que mostram que poderá haver uma relação forte entre as fotos e os eventos do calendário mas uma relação fraca com os assuntos de email.

description: Le biotecnologie riproduttive hanno conquistato, negli ultimi trentacinque anni, uno spazio sociale sempre più ampio, a livello di saperi, prassi e credenze. Questo lavoro desidera analizzarne una specifica forma, che rappresenta un punto di intersezione tra le tecniche di procreazione medicalmente assistita e la genetica clinica: la Diagnosi Genetica di Preimpianto. Attraverso una prospettiva antropologica si proverà a rispondere a tre domande: come, questa tecnica, viene utilizzata, “naturalizzata” e percepita dalle persone che vi ricorrono? Come viene costruita e rappresentata in ottica medica? Come è diventata uno dei principali nodi della legge italiana volta a disciplinarne uso e applicazioni?

description: We present the results of a search for physics beyond the Standard Model (BSM) using data of 1.1 /fb integrated luminosity collected by the CMS experiment at the LHC. Fully hadronic final states were selected based on the "stransverse" mass variable MT2 and interpreted in various models of supersymmetry (SUSY). Two complementary analyses were performed targeting different areas of the SUSY phase space. All backgrounds were estimated using both simulation and data-driven methods. As no excess of events over the expected background was observed exclusion limits were derived.

description: Da Kunststoffe in unserer Umwelt sowie in unseren Lebensmitteln und verpackten Konsumgütern allgegenwärtig sind, führt dies zu einer unvermeidlichen Exposition des Menschen. Aufgrund der Aufnahme kontaminierter Lebensmittel ist der menschliche Magen-Darm-Trakt (GIT) höchstwahrscheinlich der erste Ort der täglich Mikro- und Nanoplastik (MNP) ausgesetzt ist. Ziel der Arbeit ist die Untersuchung der Aufnahme und des intrazellulären Verbleibs von Polystyrol (PS) MNP-Partikeln unterschiedlicher Größe (0,235, 1,14 und 9,55 μm) in den humanen Darmkrebszelllinien HT29, HCT116, SW480 und SW620. Fluoreszenzmikroskopie wurde zur qualitativen Bewertung des Einflusses der Partikelgröße auf die zelluläre Internalisierung eingesetzt. Eine Lokalisierung der PS Partikeln innerhalb des lysosomalen und endosomalen Kompartiments erfolgte mittels konfokaler Laser-Scanning-Mikroskopie. Durchflusszytometrie-Experimente wurden durchgeführt, um die zelluläre Aufnahme der Partikel nach 1, 3, 6 und 24 Stunden zu quantifizieren. Für die 9,55 μm Partikel wurde keine Aufnahme in die Zellen beobachtet, jedoch konnte eine Internalisierung der 1,14 und 0,235 µm Partikeln nachgewiesen werden, welche sowohl in den Lysosomen als auch in den Endosomen lokalisiert wurden. Eine Anhäufung der 0,235 µm Partikel wurde vor allem in den Lysosomen beobachtet. Die Adhäsion an der Kernmembran sowie die Aufnahme in den Zellkern konnte für die 0,235 μm PS Partikel nachgewiesen werden. Die höchsten Aufnahmeraten (50,5 und 89,5%) nach 24 Stunden wurden bei HCT116-Zellen für die PS 1,14 bzw. 0,235 μm Partikel bestimmt. Beide PS Partikelgrößen reicherten sich dosisabhängig in allen vier Darmkrebszelllinien an. Bei niedrigen Konzentrationen (0,1 µg/ml) zeigte sich nur eine äußert geringe Aufnahme der 1,14 µm PS Partikel in die beiden Zelllinien HT29 (3,5%) und SW620 (5,8%). Bei den Zellen HCT116 (12,3 %) und SW480 (11,6 %) wurden geringfügig höhere Internalisierungsraten beobachtet. Die allgemeine Tendenz für Partikel-Zell-Interaktionen war bei 0,235 μm Partikeln deutlich höher. Selbst bei niedrigen Konzentrationen von 0,1 μg/ml wurden Aufnahmeraten von bis zu 41,7 % (für HCT116) beobachtet. Die vorliegenden Ergebnisse legen nahe, dass menschliche Darmzellen in der Lage sind, PS-MNP-Partikel zu internalisieren und dass die Größe eine wichtige Rolle bei der Aufnahme und der intrazellulären Verteilung spielt.

description: Der vorliegende Text ist ein arbeitspsychologischer Forschungsbeitrag zum International Year of Volunteering. Durchgeführt wurde - im Auftrag der Schweizerischen Gemeinnützigen Gesellschaft (SGG) - eine qualitative Organisationsanalyse zur Beschreibung von Good-Practice. Dabei handelte es sich um Organisationen, die aufgrund von Eigeninitiative gemeinwohlorientierte Aufgaben übernommen und freiwillige Mitarbeiterinnen und Mitarbeiter einbezogen haben. Die Ergebnisse zeigen deutlich, dass sich vier Beschreibungsdimensionen herauskristallisieren lassen: • sinnerzeugende ureigene Idee • Sensibilität gegenüber Zeitfragen • Sensibilität für innere soziale Prozesse • produktiver Umgang mit Hindernissen. Gelingt es den jeweiligen Organisationen diese vier Beschreibungsdimensionen gut auf einander abzustimmen und eine Balance zwischen Beständigkeit (Vermittlung der ureigenen Idee) und Wandel über die Zeit hinweg (Austausch und Nähe zur Basis)herzustellen, dann kann von Good Practice gesprochen werden. In diesem Fall ist es der Organisation bzw. Initiative gelungen Sinnprägnanz zu erzeugen. In einem zweiten Berichtsteil1 werden die der Bestimmung der Beschreibungsdimensionen und des Erfolgsfaktors zu Grunde liegenden 14 Organisationsporträts wiedergegeben. Sie ergänzen diesen Bericht und geben einen Einblick in die Selbstdarstellungen der Freiwilligeninitiativen.

description: Ziel dieser Arbeit ist es, die Auswirkungen der EU-Konditionalität im Bereich der Justizreform und der Korruptionsbekämpfung im Kandidatenland Albanien zu untersuchen. In diesem Zusammenhang wird das Prinzip der Konditionalität als sehr positiv für progressive Reformen angesehen, aber andererseits hängt das Ausmaß seiner erfolgreichen Umsetzung von verschiedenen (EU-bezogenen und internen) Faktoren ab. Ein weiteres Ziel dieser Forschungsarbeit ist es, den Europäisierungsprozess über die EU-Mitgliedsstaaten hinaus zu untersuchen und einen Beitrag zur bestehenden Literatur zur Untersuchung nationaler und externer EU-Faktoren in dem oben genannten Bereich zu leisten.
description: This thesis has the goal of investigating the impact of the EU conditionality in the field of the justice reform and anticorruption measures in the candidate country Albania. In this context, the principle of conditionality is regarded as very positive for progressive reforms but, on the other hand, the extent of its successful implementation depends on several (EU-related and internal) factors. Another aim of this research is to examine the Europeanization process beyond the EU member states and to contribute to the existing literature in the study of national and external EU factors in the above-mentioned field.

We replace singular cohomology by K-theory, and weighted cup-length arguments by considerations with biequivariant maps on spheres to improve on Farber-Grant's bounds by arbitrarily large amounts. Our calculations are based on the identification of key elements conjectured to generate the annihilator ideal of the toral bottom class in the ku-homology of the classifying space of a rank-2 abelian 2-group.

Die Erfahrungen der letzten Jahre sowie eine Vielzahl von empirischen Annahmen zur Auslegung von Bodenverbessrungsmaßnahmen mittels Rütteldruckverdichtung, geben Anlass zu genaueren Untersuchungen und Optimierungsansätzen. Mittels 1g-Modell-, Feldversuche und numerische Simulationen soll der Einfluss von Maschinenparamtern, wie Frequenz, Lagerungsdichte, Geometrie des Rüttlers, Auslegung des Verdichtungsrasters, Sättigungsgrad der Sandschicht, Art des Verdichtungsprozesses und Bodenzusammensetzung, auf den Verdichtungsgrad des Bodens ermittelt werden. Des Weiteren konnte die Schwingungsamplitude des Rüttlers als eines der Parameter zur Steuerung der Verdichtungsgrades identifiziert werden. Schließlich wurde eine Machtbarkeitsstudie zum Einfluss der Rütteldruckverdichtung zur Reduktion des Verflüssigungspotential in gesättigtem Sand infolge seismischer Aktivität durchgeführt.
description: Deep vibration compaction is an established ground improvement technique for granular materials. The field experience and empirical relations used for the design of deep vibration compaction processes prompt further study and analysis. 1g model tests, field measurements and numerical simulations evaluated effect of frequency, relative density, shape of vibrator, spacing of compaction points, saturation of sand layer, nature of compaction process and type of sand; on the extent and degree of compaction. Vibrator amplitude was identified as an on-line compaction control parameter. Feasibility of deep vibration compaction for liquefaction mitigation was analysed via seismic site response of saturated sand before and after deep vibration compaction by means of numerical simulations.

description: A wide variety of problems in global optimization, combinatorial optimization as well as systems and control theory can be solved by using linear and semidefinite programming. Sometimes, due to the use of floating point arithmetic in combination with ill-conditioning and degeneracy, erroneous results may be produced. The purpose of this article is to show how rigorous error bounds for the optimal value can be computed by carefully postprocessing the output of a linear or semidefinite programming solver. It turns out that in many cases the computational costs for postprocessing are small compared to the effort required by the solver. Numerical results are presented including problems from the SDPLIB and the NETLIB LP library; these libraries contain many ill-conditioned and real life problems.

description: We study models of itinerant spinless fermions with random long-range interactions. We motivate such models from descriptions of fermionic atoms in multi-mode optical cavities. The solution of an infinite-range model yields a metallic phase which has glassy charge dynamics, and a localized glass phase with suppressed density of states at low energies. We compare these phases to the conventional disordered Fermi liquid, and the insulating electron glass of semiconductors. Prospects for the realization of such glassy phases in cold atom systems are discussed.

description: SoA Ni cermet based SOECs is known to be very sensitive to impurities such as sulfur components, especially for CO2
 electrolysis, where cleaning of sulfur in CO2 down to sub-ppb level is required, which maybe an expensive process since
 sulfur is a very common impurity in CO2 captured from post- combustion sources. It is therefore arguable whether co-
 electrolysis is economical beneficial if SOEC can only be supplied with very high purity CO2.
 Considering the fact that most of synthetic fuel production processes are performed under elevated temperature and
 technologies based on the WGSR is at a very mature state. If cheap H2 could be produced by SOEC, and syngas could be
 made by CO2 hydrogenation or WGSR without large efforts in deep cleaning of the CO2. Understanding the degradation of
 SOEC under different inlet gas compositions is therefore important from both a technological and economic point of view.

description: This data resource contains the Best Linear Unbiased Estimates of 135 elite winter wheat (Triticum aestivum L.) lines adapted to Central Europe and 1,604 F1
			hybrids derived from them. All genotypes were evaluated for seven quality traits in up to six environments (Zhao et al. 2015; Proceedings of the National Academy of Sciences of the United States of
			America 112:15624-15629; DOI: 10.1073/pnas.1514547112; Liu et al. 2016. Liu et al. 2016; PlosOne; DOI: 10.1371/journal.pone.0158635). The sedimentation (SDS) volume according to Zeleny (unit ml)
			providing a measure for gluten content and swelling properties and thus baking quality of wheat was determined in accordance with International Association for Cereal Science and Technology (ICC)
			Standards 116/1 and 118 (http://www.icc.or.at/standard_methods). Protein, gluten, and starch content (unit %) as well as hardness were determined by near infrared reflectance (NIR) spectroscopy in
			accordance to ICC Standard 159 (http://www.icc.or.at/standard_methods). 1000-kernel weight (unit g) and test weight (unit kg hL-1) were determined in accordance with variety registration

description: We discuss the strong-field dynamics of HeH+, the simplest stable heteronuclear molecule, focusing on identifying a laser regime for which there is a sufficient dissociation signal for experimental measurement. We numerically solve the time-dependent Schrödinger equation to obtain total dissociation probabilities, kinetic energy release spectra, and momentum distributions for wavelengths from 800 nm to 2400 nm. The suitability of this simple system as a prototype for understanding the strong-field nuclear dynamics of heteronuclear dissociation is discussed.
In vitro studies of allelic variation and function of aldo-keto reductases 1A1 and 1C2
Creators: name: Takahashi, Ryan Hiro
Publisher: name: University of British Columbia
Year: 2009

description: The aldo-keto reductases (AKR) are a superfamily of enzymes involved in metabolizing a variety of endogenous and xenobiotic chemicals. These biotransformation reactions are being recognized as important bioactivation or deactivation steps in humans that may determine the efficacy or toxicity of drug therapy or disease development. Consequently, the factors that affect the function of AKRs may be critical determinants for interpatient differences in therapeutic response and likelihood for disease occurrence. The metabolism of anthracycline drugs and androgen steroids are proposed to be involved in drug-induced cardiotoxicity and prostate cancer development, respectively. In the former case, the metabolism of anthracyclines can generate reactive species or toxic metabolites that are damaging to heart tissue. In the latter case, metabolic pathways that synthesize, interconvert, and deactivate androgen steroids regulate androgen receptor activation, and imbalance of these processes may promote abnormal prostate growth. The occurrence of both disorders is highly unpredictable, which may be, in part, due to interpatient variability in metabolism. The anthracyclines doxorubicin (DOX) and daunorubicin (DAUN) and the androgen steroid dihydrotestosterone (DHT) are substrates for two human isoforms of AKR protein, namely AKR1A1 and AKR1C2. Thus, factors affecting the function of these enzymes may contribute to altered metabolism and development of these conditions. The goal of this project is to characterize the function of AKR1A1 and AKR1C2 in metabolizing the anthracyclines DOX and DAUN, and the androgen steroid DHT using in vitro techniques. The naturally-occurring allelic variations in the coding regions of the AKR genes are compared to wild-type to identify their association with impaired reductase function. In addition, allosteric activation of AKR1C2, which has not been confirmed since its first report in the literature, is investigated for its relevance to DHT metabolism. The results of these studies demonstrate that genetic variation and chemical modulation can significantly alter the metabolism of DOX, DAUN, or DHT and, therefore, potentially contribute to the variability in patient response to these chemicals. These data can form a foundation of biochemical evidence to design in vivo studies that will elucidate the role of altered metabolism in developing anthracycline-associated cardiotoxicity and prostate cancer.

description: The Large Synoptic Survey Telescope will be an 8.4m optical survey telescope sited in Chile and capable of imaging the entire sky twice a week. The data rate of approximately 15 TB per night and the requirements to both issue alerts on transient sources within 60 seconds of observing and also to create annual data releases means that automated data management systems and data processing pipelines are a key deliverable of the LSST construction project. The LSST data management software has been in development since 2004 and, like other software developed in that era such as CASA, is based on a C++ core with a Python control layer. The software consists of nearly quarter of a million lines of code covering the system from fundamental WCS and table libraries to pipeline environments and distributed process execution.

The Astropy project began in 2011 as an attempt to bring together disparate open source Python projects and build a core standard infrastructure that can be used by and built upon by the astronomy community. This project has been phenomenally successful in the years since it has begun and has grown to be the de facto standard for Python software in astronomy. Astropy brings with it considerable expectations from the community on how astronomy Python software should be developed and it is clear that by the time LSST is fully operational in the 2020s many of the prospective users of the LSST software stack will assume that Astropy software will be integrated.

In this paper we will describe the overlap between the LSST science pipeline software and Astropy software and investigate areas where the LSST software provides new functionality. We will also discuss the possibilities of re-engineering the LSST science pipeline software to build upon Astropy, including the option of contributing a liated packages.

description: State of the art X-ray imaging sensors comprise a trade-off between the achievable efficiency and the spatial resolution. To overcome such limitations, the use of structured and scintillator filled aluminum oxide (AlOx) matrices has been investigated. We used Monte-Carlo (MC) X-ray simulations to determine the X-ray imaging quality of these AlOx matrices. Important factors which influence the behavior of the matrices are: filling factor (surface ratio between channels and 'closed' AlOx), channel diameter, aspect ratio, filling material etc. Therefore we modeled the porous AlOx matrix in several different ways with the MC X-ray simulation tool ROSI [1] and evaluated its properties to investigate the achievable performance at different X-ray spectra, with different filling materials (i.e. scintillators) and varying channel height and pixel readout. In this paper we focus on the quantum efficiency, the spatial resolution and image homogeneity.

description: We present SMA and CARMA continuum and spectral line observations of five dense cores located in the Perseus and Ophiuchus molecular clouds whose masses exceed their thermal Jeans masses. Three of these cores have previously been identified as being starless and two have been classified as being possibly protostellar. We find that one core is certainly protostellar. The other four cores, however, are starless and undetected in both C18O (2-1) and 1.3mm continuum emission. These four starless cores have flat density profiles out to at least 0.006 pc, which is typical for starless cores in general. Density profiles predicted by some collapse models, especially in the early stages of infall, are consistent with our observations. Archival data reveal that these starless cores have significant non-thermal support against collapse, although they may still be unstable.

description: Der Ausgangspunkt für die vorliegende Arbeit ist die Newmansche auf grenzschichtähnlichen Abschätzungen beruhende Lösung des Impulssatzes für das laminare Geschwindigkeits- und Druckfeld eines aufgerollten Tragflügel-Spitzenwirbels. Es wird gezeigt, daß es durch eine an die Theorie turbulenter Grenzschichten angelehnte Modifikation des Ansatzes für den Kernradius möglich ist, eine Näherungslösung für das turbulente Strömungsfeld eines aufgerollten Spitzenwirbels zu erhalten. Dabei ergeben sich realistische Ausdrücke für die Reynolds-Spannungen. Unter Verwendung des dabei erhaltenen Minimaldrucks im Zentrum des Spitzenwirbels ist es möglich, den Beiwert des Kavitationseinsatzes in Abhänigkeit von Auftriebsbeiwert und Reynolds-Zahl des Flügels vorauszuberechnen. Ebenso gelingt es, für andere Kavitationsbeiwerte eine Näherungsformel für den Radius des Dampfbereichs im Spitzenwirbel anzugeben. Schließlich wird gezeigt, daß sich die Ergebnisse der Theorie auch auf Propellerspitzenwirbel übertragen lassen. Der Vergleich der theoretischen Resultate mit Meßdaten, die sowohl..bei Tragflügeln als auch bei Propellern gewonnen wurden, ergibt eine noch annehmbare Übereinstimmung.

description: The study investigated the impact of crude oil price fluctuations on selected economic sectors in Nigeria from 1986 to 2021. The data for the study, sourced from the Central Bank of Nigeria statistical Bulletin of various volumes, was analysed using Autoregressive Distributed Lag (ARDL) approach. The study focused on the Agricultural, Information and Communication and Manufacturing sectors of the Nigeria economy. The results of the analysis showed that a long–run relationship existed between crude oil price fluctuations and the sampled sectors’ returns. Specifically, the study found that crude oil price fluctuations had a negative and significant effect on agricultural and telecommunication sector in the long-run, while its effect on the manufacturing sector was positive and statistically significant at 5% level. Hence, it was recommended among other things that Nigeria should diversify her export revenue base as a means of minimizing reliance on crude oil and petroleum products
