Experimentelle Untersuchungen an Plattenbalken zeigen, dass Querkraftverstärkungen auch außerhalb der Biegedruckzone verankert werden können. Entscheidend dabei ist, dass alle in der Verbundfuge von Altbeton und Verstärkung auftretenden Beanspruchungen durch die Haftzug- und Scherfestigkeit des Alt- und Feinbetons übertragen werden können. Ein Verbundversagen führt durch das Ablösen der Verstärkungsschicht zu deren Ausfall. Der Beitrag befasst sich mit den Beanspruchungen und Versagensmechanismen des Verankerungsbereiches, die anhand von Versuchsergebnissen dargestellt werden. Als Versagenskriterium für die Verankerung sind zwei flächige Versagensarten – der Altbetonuntergrund und die Ebene der textilen Bewehrung – zu berücksichtigen. Als weiteres Versagenskriterium der Verankerung ist der innere Verbund zwischen den Multifilamentgarnen und der sie umgebenden Feinbetonmatrix zu betrachten. Für die Bemessung des Verankerungsbereiches einer Verstärkung wird der jeweils ungünstigste Wert dieser drei Versagensarten maßgebend.

In First-Person shooter video games, spread is a mechanic that adds a random artificial inaccuracy to the player’s shots. Movement-amplified spread is a particular implementation of spread which amplifies the inaccuracy based on the speed the player is moving at. As a consequence, players that are moving are unable to fire accurate shots, whereas players standing still remain accurate. The purpose of this thesis is to study the effects of movement-amplified spread of different intensities on gameplay dynamics. To this end, we created a First-Person shooter target practice course for testers to complete 15 times. For every third completion we made movement-amplified spread more intense. The results showed that as movement-amplified spread increased, testers were more prone to halt before shooting, firing more shots and engaging with targets at a somewhat shorter distance. / I förstapersonsskjutare, även kallat FPS, är spread en spelmekanik som applicerar enslumpmässig inexakthet till spelarens precision när de skjuter. Movement-amplified spread ären specifik implementering av spread som amplifierar inexaktheten baserat på spelarens rörelse och hastighet. Som en konsekvens av detta så har spelare som rör på sig svårt att samtidigt vara träffsäkra, medan spelare som står still förblir precisa. Syftet med denna uppsats är att studera hur effekterna av en ökande movement-amplified spread påverkar spelkänsla och dynamik i spel. För detta har vi byggt en FPS hinderbana med stationära mål som testare har fått springa igenom 15 gånger. För vart tredje genomförande har vi ökat intensiteten av movement-amplified spread. Resultaten visar att när movement-amplified spread ökade, så var testarna mer benägna att stanna före de avlossade skott, de sköt mer eller så sprang de närmare för att bekämpa måltavlorna på ett kortare avstånd.

<p>Coupled Composite Plate Shear Walls / Concrete Filled (CC-PSW/CFs) are being employed as a seismic lateral force resisting system for the design and construction of mid- to high-rise buildings around the world. The coupled system consists of two or more Composite Plate Shear Walls – Concrete Filled (C-PSW/CFs) connected to each other using composite coupling beams located at the story heights. The CC-PSW/CF system can provide higher overturning moment capacity, lateral stiffness, and ductility than uncoupled walls. Concrete-filled steel box sections are typically used for the composite coupling beams, which are designed to be flexure critical members. When the CC-PSW/CF system is subjected to lateral seismic forces, plastic hinge formation and inelastic deformations (energy dissipation) occur near the ends of most of coupling beams along the structure's height, followed by flexural hinging of the C-PSW/CFs, typically at the base. </p> <p>This work presents the details and design of four composite coupling beam-to-C-PSW/CF connection configurations. Six connection specimens, representing the four connection configurations, with beam clear span-to-section depth, <em>Lb</em>/<em>d</em>, ratios of 3.5 and 5.1, were designed, fabricated, and tested. The experimental program focused on the force-displacement and moment-rotation responses, behavioral observations, limit states, and flexural capacities of the tested specimens. Major limit states and events included yielding of the steel plates comprising the coupling beam, followed by local inelastic buckling, fracture initiation in the base metal (near the weld toes) in the connection region, and fracture propagation through the beam flange and web plates leading to loss of flexural strength and failure. All specimens developed and exceeded the capacity and chord rotation requirements, in accordance with ANSI/AISC 341-22 guidelines.</p> <p>Detailed nonlinear 3D finite element models of the tested specimens were developed and verified using experimental results. The 3D finite element models accurately simulate the stiffness, flexural capacities, and monotonic responses of tested specimens. Nonlinear fiber-based models of the tested coupling beam-to-C-PSW/CF specimens were developed and verified using experimental results. The nonlinear fiber-based models can accurately simulate the stiffness, flexural capacities, and cyclic responses of tested specimens. The benchmarked fiber models were used to estimate the moment-rotation response of full-scale archetype connections. </p>

A handful of studies have shown that National Inter-religious Councils (NIRCs) contribute to electoral violence prevention. However, no quantitative study has evaluated the impact of their interventions and the conditions under which they lower electoral violence. Using data on African national elections from 1992-2019, I examine whether NIRCs' electoral-related peacebuilding interventions lower the severity of electoral violence and if their ability to do so depends on NIRCs' social power. The results in this thesis indicate that the presence of NIRCs' interventions during electoral rounds lowers the likelihood of severe electoral violence. The findings also reveal a significant disordinal interaction between NIRCs' interventions and their power, where the predicted probability of severe electoral violence reduces by 42% when powerful NIRCs implement peacebuilding interventions and, on the other hand, increases by 20% when less powerful NIRCs intervene. While this thesis fails to explain the disordinal interaction effect, it details this study's methodological tools and limitations and contributes an original dataset of NIRCs' interventions and power for future research.

The aim of this investigation was to determine whether there is a significant difference in the academic achievement of sixth grade Science students when teaching styles are matched to their learning styles. The research problem is encompassed in the following question: "Is there a relationship between matching teaching and learning styles and the academic success in Science?" A quantitative approach was undertaken, specifically, the pretest-posttest control group experimental design. The population comprised of sixth grade students selected according to a non-probability sampling method of convenience. The sample comprised of two class units randomly selected. The dependent sample t-test inferential statistic was used to analyze the data collected. The results indicated a statistically significant difference between the pretest and posttest scores of the experimental group. The conclusion reached is that matching teaching styles to learning styles improves the academic success of sixth grade learners in Science. / Educational Studies / M.Ed. (Educational Psychology)

Dieser Beitrag befasst sich mit der experimentellen und analytischen Bestimmung der Verankerungslängen textiler Bewehrungsstrukturen einer Textilbetonverstärkungsschicht. Die experimentelle Untersuchung des Verbundverhaltens erfolgte anhand von Pull-Out-Versuchen. Die analytische Betrachtung des Verbundproblems geschieht aufbauend auf multilinearen Lösungen der Verbunddifferentialgleichung anhand der experimentell ermittelten Kraft- Rissöffnungs-Beziehungen. Mit Hilfe eines separaten Modells wird aus der so ermittelten Verbundspannungs-Schlupf-Beziehung (VSB) die zur Verankerung einer entsprechenden Kraft F erforderliche Verankerungslänge lE bestimmt. Die Überprüfung der Berechnung erfolgt anhand von unabhängig in experimentellen Versuchen zur Bestimmung der Verankerungslänge ermittelten Werten. Es konnte eine gute Übereinstimmung der berechneten mit den versuchstechnisch bestimmten Verankerungslängen festgestellt werden.

This thesis aims to increase understanding of New Zealand consumer reactions to messages promoting genetically modified food products (GMFs) and to determine how the manipulation of three persuasion variables, message sidedness, source credibility and inward vs. outward focus impact upon consumer attitudes. To achieve this aim, the study integrated two frameworks, Bredahl's, (2001) determinants of attitudes towards GMFs and Wansink and Kim's, (2001) strategies for educating consumers about GMFs, into a new model. To empirically examine the model, a web-based experiment using a 2x2x2 between-subjects factorial design was conducted. The experiment exposed participants to one of eight treatment groups containing a promotional message for Genetically Modified foods. The participants then completed an on-line questionnaire detailing their responses to the messages. A total of 380 useable questionnaires were collected from a national sample of consumers and analysed using ANCOVA. The results of the study suggest that the outwardly focused, two-sided message was more powerful at lowering perceptions of risks, raising perceptions of benefits and positively influencing attitudes toward the ad than either the one-sided, outwardly focused message, or the inwardly focused messages of either sidedness condition. For purchase intentions individual differences appeared to be of greater influence than message factors.

Plant removal experiments are useful to elucidate these mechanisms because its cause and effect response. This thesis aims to analyze experiments removal plants. The first paper presents a scientometric review of the literature on plant functional groups removal 1991. We verify aspects such as the number of publications and citations in journals indexed in the Web of Science, which country was made in order to detect bias and geographic gaps, which ecological effects were tested, which functional groups were removed, which removal methods and which environments were made. We found an increase in the number of publications and citations on average during this period, however, was 12 times lower than publications on functional diversity, perhaps due to the difficulty of conducting experiments. The work was mainly carried out in temperate climates where taxonomic knowledge is greater, in addition, there is a prevalence of vegetation that is most commonly removed than trees. Testing interactions, especially competition, was the main reason for removal, perhaps as a matter of historical competition is considered the interaction that influences the co-occurrence of species. The cut at ground was the major method of removing, undisturbing the soil and avoiding undesirable effects of herbicides, and few studies have been made in a greenhouse and in the natural environment at the same time, which could elucidate responses to natural conditions and at the same time responses specific interactions. In the second paper we carried a case study on removal of capim-flecha ( Tristachya leiostachya Ness.), a dominant grass in Emas National Park (ENP), and what the consequences of such removal to the co-occurring grasses. We expected that the absence of capim-flecha allow further growth of grasses, however we found no difference in mean values between treatments indicating that there is no competition influencing the abundance of capim-flecha. The historical context burned in PNE may have influenced this high dominance of capim-flecha. We believe that experiments are useful in testing interactions, especially if they are made in the natural environment and greenhouse at the same time. / As relações entre os organismos e os mecanismos que permitem sua coexistência são importantes questões em ecologia. Experimentos de remoção de plantas são úteis em elucidar esses mecanismos, devido sua capacidade de resposta do tipo causa e efeito. Esta dissertação se propõe a analisar experimentos de remoção de plantas. O primeiro artigo apresenta uma revisão cienciométrica das publicações sobre remoção de grupos funcionais de plantas, desde 1991. Verificamos aspectos como o número de publicações e citações em periódicos indexados no Web of Science, em qual país foi feito, visando detectar vieses e lacunas geográficas, quais efeitos ecológicos testados, quais grupos funcionais removidos, quais os métodos de remoção e em quais ambientes foram feitos. Encontramos um crescimento no número de publicações bem como na média de citações nesse período, contudo foi 12 vezes menor do que publicações sobre diversidade funcional, talvez devido à dificuldade de realizar experimentos. Os trabalhos foram realizados principalmente em climas temperados onde o conhecimento taxonômico é maior, além disso, há um predomínio de vegetação rasteira que é mais comumente removida do que árvores. Testar interações, principalmente competição, foi o principal motivo de remoção, talvez por uma questão histórica de competição ser considerada a interação que mais influencia a co-ocorrência de espécies. O corte rente ao solo foi o principal método de remoção, evitando revolver o solo e efeitos indesejáveis de herbicidas, e poucos trabalhos foram feitos em casa de vegetação e ambiente natural ao mesmo tempo, o que poderia elucidar respostas à condições naturais e ao mesmo tempo respostas específicas de interações. No segundo capítulo fizemos um estudo de caso sobre remoção de capim-flecha (Tristachya leiostachya Ness.), uma gramínea dominante no Parque Nacional das Emas (PNE), e quais as consequências dessa remoção para as gramíneas co-ocorrentes. Esperávamos que a ausência do capim-flecha permitiria um maior crescimento das gramíneas, contudo não encontramos diferença nos valores das médias entre os tratamentos o que indica que não há competição influenciando a abundância do capim-flecha. O contexto histórico queimadas no PNE pode ter influenciado essa alta dominância do capim-flecha. Consideramos que experimentos são úteis em testar interações, sobretudo se forem feitos em ambiente natural e casa de vegetação ao mesmo tempo.
