The goal of this thesis study is to investigate the Ambiguity Function Technique for target detection in phase-coded continuous wave radar. Also, phase shift keying techniques are examined in detail. Continuous Wave (CW) Radars, which are also known as Low Probability of Intercept (LPI) radars, emit continuous signals in time which are modulated by either frequency modulation or phase modulation techniques. Modulation of the transmitted radar signal is needed to estimate both the range and the radial velocity of the detected targets. In this thesis, Phase Shift Keying (PSK) techniques such as the Barker codes, Frank codes, P1, P2, P3, P4 codes will be employed for radar signal modulation. The use of Ambiguity Function, which is a non-linear Time- Frequency Representation (TFR), for target detection will be investigated in phasecoded CW radars for different target scenarios.

A indústria da construção civil é considerada como uma das grandes causadoras de impactos negativos ao meio ambiente, desde a extração de matéria prima, até o fim de vida de seus empreendimentos. Dentre os principais impactos ambientais ocasionados pelo setor, destacase a geração de resíduos de construção civil (RCC), a qual é intensificada em função do desenvolvimento de grandes centros urbanos e a consequente necessidade de implantação de empreendimentos de infraestrutura. Nesse contexto, uma das estratégias mais eficientes para redução de RCC está associada à realização de escolhas adequadas na fase de projeto, com enfoque de prevenção na fonte geradora. No entanto, é complexa a inclusão de fatores de sustentabilidade, tais como os de minimização de RCC, em projetos da construção civil. Logo, torna-se relevante a adoção de métodos e ferramentas de suporte ao processo decisório. Contudo, os métodos existentes são direcionados, em sua maioria, a projetos de edificações, havendo uma importante lacuna associada a projetos de infraestrutura urbana. Assim sendo, esta pesquisa objetiva a proposição de mecanismos de apoio à tomada de decisão, para a minimização de RCC, em projetos de infraestrutura urbana, com dois diferentes enfoques: controle e avaliação; e estrutura de orientação. Para a composição dos mecanismos de controle e avaliação, foram identificadas boas práticas para redução da geração de RCC na fase de projeto, a partir de pesquisa bibliográfica, análise documental de projetos, e pesquisa quali-quantitativa junto a especialistas. Essas boas práticas deram origem a demandas ambientais a serem atendidas pelos projetos de infraestrutura urbana, motivando a elaboração de um método estruturado para gerenciamento de requisitos ambientais e de trade-offs, como apoio à tomada de decisão projetual. O método teve como base a ferramenta Quality Function Deployment (QFD), no qual foi desdobrada a Matriz da Qualidade, a partir da opinião de especialistas atuantes em diferentes etapas do desenvolvimento de projetos de infraestrutura urbana. Como principais contribuições da pesquisa, focada na minimização de RCC, podem ser consideradas: (i) a obtenção de um checklist, como instrumento de controle e avaliação da qualidade dos projetos a serem desenvolvidos; (ii) a identificação de requisitos e de indicadores ambientais prioritários associados a esses projetos; e (iii) a elaboração de uma sistemática para gerenciamento de trade-offs existentes em projetos de infraestrutura urbana menos impactantes ambientalmente. / The construction industry is considered as one of the great causes of negative impacts to the environment, from the extraction of raw material, until the end-of-life of its projects. Among the main environmental impacts caused by the sector, can be highlighted the generation of construction waste (CW), which is intensified due to the development of large urban centers and the consequent need to implement infrastructure projects. In that context, one of the most efficient strategies to reduce CW is associated with making adequate choices in the design phase, with a focus on prevention at the source. However, it is complex to include sustainability factors, such as CW minimization, in construction designs. Therefore, it is relevant to adopt methods and tools to support the decision-making process. However, the existing methods are mostly directed to building designs, with an important gap associated with urban infrastructure designs. Thus, this research aims at proposing mechanisms to support decision making for the CW minimization in urban infrastructure projects, with two different approaches: control and evaluation; and guidance structure. For the composition of the control and the evaluation mechanisms, best practices were identified to reduce the CW generation in the design phase, based on literature review, documentary analysis of projects, and qualitative and quantitative surveys with specialists. Those best practices have given rise to environmental demands to be met by urban infrastructure projects, motivating the elaboration of a structured method for managing environmental requirements and trade-offs, as a support for the decision making design. The method was based on the Quality Function Deployment (QFD) tool, in which the quality matrix deployment, based on the opinion of specialists working in different stages of the development of urban designs. The main contributions of the research, focused on the CW minimization, can be considered: (i) obtaining a checklist, as an instrument to control and evaluate the quality of the designs to be developed; (ii) identification of requirements and of priority environmental indicators associated with those projects; and (iii) the development of a systematic for managing tradeoffs in urban infrastructure projects that are less environmentally impacting.

This project deals with possibilities of using the software defined radio conception for radio amateur use in a short wave band and its subsequent implementation into properly designed hardware. The aim of this work is to design a transceiver that would be capable of working in AM, FM, SSB, and CW modes. Within a theoretical part of the project the architectures of software defined radios and their components are discussed. This part was focused mainly on analog parts of the chain, such as amplifiers, filters and converters. Signal processing algorithms for both receiver and transmitter working in desired modes are studied subsequently and their computer models are built. Designed algorithms are implemented into FPGA structure (Virtex -5).

We generalize Forman’s discrete Morse theory, on one end by developing a discrete analogue of Morse-Bott theory for CW complexes, motivated by Morse-Bott theory in the smooth setting. On the other, motivated by J-N. Corvellec’s Morse theory for continuous functionals, we generalize Forman’s discrete Morse-floer theory by considering a vector field more general than the one extracted from a discrete Morse function, and defining a boundary operator from which the Betti numbers of the CW complex are obtained. We also do some Conley theory analysis.

Die psychische Belastung im Arbeitsprozess wurde international und national zu einem Kernproblem für den Arbeitsmarkt. Das deutsche Arbeitsschutzgesetz fordert nunmehr ausdrücklich auch das Vermeiden von Gefährdungen durch psychische Belastung. Diese Checkliste hilft als Orientierungsverfahren zu ermitteln, ob in Betrieben und Einrichtungen eine eingehendere Untersuchung psychischer Belastung erforderlich ist und welche Schwerpunkte gegebenenfalls vorliegen. Für eingehendere Untersuchungen existieren zahlreiche Verfahren. Die Checkliste ist branchenübergreifend einsetzbar, nicht zutreffende Sachverhalte sind gegebenenfalls zu überspringen.

This study investigates the effectiveness of adopting a Creative Writing method to motivate and develop vocabulary learning in an ESL/EFL (English as a second language/English as a foreign language) context. This research also investigates the effectiveness of adapting CW as a teaching method and its approaches for facilitating vocabulary learning for upper-secondary English students. From this, we analyzed 12 empirical research from the year 2006 to 2021 by research reviewing studies on CW and synthesizing the commonalities. Our study showed promising results, which indicates that CW is a beneficial asset for teachers to increase student engagement and vocabulary acquisition for ESL/EFL learners overall that is applicable in Sweden.

Wann und warum entscheiden sich Menschen für unehrliches Verhalten? Durch das Verständnis von unehrlichem Verhalten sind politische Entscheidungsträger besser in der Lage, ein solches Verhalten zu verhindern und eine florierende Gesellschaft und Wirtschaft zu unterstützen. Das Studium der Unehrlichkeit hat in den letzten Jahren eine Blütezeit erlebt, angetrieben durch die Etablierung von Crowd-Sourced-Arbeitsplattformen, obwohl auch einige wichtige Feldarbeiten entstanden sind. Die empirischen Erkenntnisse aus diesen Studien haben die Entstehung neuer ökonomischer und psychologischer Modelle zur Erklärung unehrlichen Verhaltens unterstützt. Doch wie replizierbar und verallgemeinerbar sind die führenden experimentellen Ergebnisse? Und welche anderen kontextuellen Faktoren wie die Art und das Ausmaß der Belohnung und die Designentscheidungen des Experimentators können unehrliches Verhalten beeinflussen? Im Mittelpunkt dieser Arbeit stand der Versuch der Replikation einer in der akademischen Welt und in der populären Presse viel zitierten Arbeit. Frühere Replikationsversuche haben diese Arbeit umgangen, da es schwierig war, Zugang zu professionellen Teilnehmern zu bekommen. Die Arbeit, die wir zu wiederholen versuchten, ergab, dass nur Banker, deren berufliche Identität hervorgehoben wurde, sich unehrlich verhielten. Diese Arbeit basierte auf der Vorstellung, dass das Priming, also das Hervorheben eines Aspekts der Identität einer Person und der damit verbundenen Normen, das Verhalten beeinflussen würde. Da das Priming der professionellen Bankidentität Unehrlichkeit auslöste, wurde daraus geschlossen, dass dies ein Hinweis auf problematische Normen im Bankensektor ist. Es war jedoch unklar, ob dieses Ergebnis auch für andere Banken gilt, z. B. in der gleichen oder einer anderen Gerichtsbarkeit, in verschiedenen Segmenten (z. B. Commercial versus Investment Banking) und im Zeitverlauf. / When and why do people decide to behave dishonestly? By understanding dishonest behaviour, policy makers are better able to deter such behaviour and to support a thriving society and economy. The study of dishonesty has flourished in recent years, driven by the establishment of crowd-sourced labour platforms, though some important field work has also emerged. The empirical findings from these studies have supported the emergence of new economic and psychological models to explain dishonest behaviour. Yet, how replicable and generalisable are leading experimental findings? And what other contextual factors -- like the nature of reward, scale of reward, and design choices from the experimenter-- may drive dishonest behaviour? The central focus of this thesis was the attempted replication of a heavily cited paper in academia and the popular press. Previous replication efforts by-passed this work given the challenge of accessing professional participants. The paper which we attempted to replicate found that only bankers whose professional identity was made salient behaved dishonestly. This work was based on the notion that priming, or making salient one aspect of an individual’s identity and the associated norms, would affect behaviour. As priming professional banking identity prompted dishonesty, this was concluded to be indicative of problematic norms in the banking sector. Though it was unclear if this finding would hold with other banks, for example in the same or other jurisdictions, in different segments (e.g. commercial versus investment banking), and over time.

Interessen werden meist aus einer Trait- oder State-Perspektive beforscht. Erst kürzlich wurden die beiden Perspektiven in einem theoretischen Modell integriert (Su et al., 2019), das postuliert, dass sich Interesse-Traits als intraindividuell variierende States manifestieren. Aufbauend auf dieses Modell untersucht die vorgelegte Dissertation Interessen anhand der wichtigsten Taxonomie für Interesse-Traits—Hollands (1997) Taxonomie beruflicher Interessen. Das Ziel dieser Dissertation ist zu untersuchen, ob und wie sich Berufsinteresse-Traits als States im Alltag manifestieren. Kernstück dieser Arbeit bilden zwei präregistrierte Experience Sampling Studien. Sie werden mit einem Literaturüberblick zu Interesse-Traits und -States eingeleitet sowie der Identifizierung von zwei Forschungszielen: Die Untersuchung (1) der Natur alltäglicher Manifestationen von Interesse-Traits und (2) der Korrelate von Interesse-States. Beide Studien verfolgten diese zwei Forschungsziele. Zentrale Ergebnisse waren, dass (1) Personen systematisch in ihren Interesse-States im Alltag variieren; (2) ein spezifisches Variabilitätsmuster in Interesse-States die Natur von Interesse-States von derjenigen von Persönlichkeit-States zu unterscheiden scheint; (3) Interesse-States systematisch mit spezifischen situations- und personenbezogenen Variablen assoziiert sind. Die Dissertation schließt mit einer Zusammenfassung, wie die beiden Studien zu den identifizierten Forschungszielen beitragen und einer Diskussion der allgemeinen Stärken, Limitationen und Anregungen für künftige Forschung. Theoretische Implikationen werden vorgestellt und in das integrative Modell (Su, et al., 2019) eingebettet. Insgesamt beleuchtet die vorgestellte Forschung die Natur und Korrelate momentaner Manifestationen von Berufsinteressen im täglichen Leben und kann künftige Forschung dazu anregen, stärker eine State-Perspektive auf Interessen zu berücksichtigen. / Research on interests is typically conducted with a trait or state perspective. Only recently, the two perspectives have been integrated within a theoretical model (Su et al., 2019), proposing that interest traits manifest as intraindividually varying states. Based on this model, this dissertation examines interests as conceptualized with the most prominent interest trait taxonomy—Holland’s (1997) taxonomy of vocational interests. With this dissertation, I sought to explore whether and how vocational interest traits manifest as states in daily life. Two preregistered experience sampling studies are this dissertation’s core. They are introduced with a literature overview on interest traits and states and an identification of two research goals: Exploring (1) the nature of interest trait manifestations in daily life and (2) correlates of interest states. While the first study provided first empirical answers on the nature and correlates of vocational interest states in daily life, the second study sought to refine these insights. The key findings of the two studies are that (1) persons systematically vary in their vocational interest states in daily life; (2) a distinctive pattern of interest state variability seems to set the nature of vocational interest states apart from the nature of Big Five personality states; (3) vocational interest states are systematically associated with specific situation- and person-related variables. The dissertation concludes with a summary of how the two studies contribute to the identified research goals and a discussion of the studies’ general strengths, limitations, and suggestions for further research. Theoretical implications are presented and associated with the integrative model of interests (Su, et al., 2019). Altogether, shedding light on the nature and correlates of vocational interest states in daily life, the presented research may encourage future work to consider a state perspective in research on vocational interests.

Die Personalausauswahl an Universitäten ist von hoher Relevanz. Die vorliegende Disseratation beschäftigt sich mit den Auswahlprozessen von Studierenden, Promovierenden und Postdocs und den Berufungsverfahren von Professor:innen. Der Fokus liegt auf drei elementaren Punkten der Prozesse: Verwendungshäufigkeit, Kriteriumsvalidität und Akzeptanz. Die Arbeit beantwortet die Fragen, welche Verfahren bei der Personalauswahl an Universitäten genutzt werden, wie gut sich mit verschiedenen Verfahren und Konstrukten der Erfolg von Studierenden, Promovierenden und Postdocs, und Professor:innen vorhersagen lässt und wie akzeptiert verschiedene Verfahren bei Personalauswahlverfahren an Universitäten sind. In zwei eigenen Studien werden Forschungslücken geschlossen und neue Erkenntnisse der Literatur ergänzt. Für Studie 1 wurde bei N = 164 Promovierenden erhoben, wie diese tatsächlich ausgewählt wurden. Promotionsstellen wurden am häufigsten durch frei geführte Auswahlgespräche und persönliche Kontakte besetzt. Bei N = 170 potenziellen Bewerbenden für eine Promotionsstelle wurden die Akzeptanzurteile für Auswahlverfahren erfragt. Frei geführte Auswahlgespräche, berufliche Erfahrungen, Arbeitsproben und strukturierte Auswahlgespräche erhielten die höchsten Akzeptanzwerte. Studie 2 beleuchtet die Kriteriumsvalidität und identifizierte Prädiktoren, die in einem Längsschnittdesign sowohl den objektiven als auch den subjektiven Laufbahnerfolg zwei Jahre nach Abschluss der Promotion bei N = 2 104 erfolgreich Promovierten vorhersagen konnten. Die Big Five Persönlichkeitseigenschaften Offenheit für neue Erfahrungen und Neurotizismus waren Prädiktoren für objektiven Laufbahnerfolg. Verträglichkeit und Neurotizismus konnten unterschiedliche Aspekte von subjektivem Laufbahnerfolg vorhersagen. Darüber hinaus konnte mittels Response Surface Analysen ein Persönlichkeits-Anforderungs-Fit in Offenheit für neue Erfahrungen und Extraversion objektiven Laufbahnerfolg vorhersagen. / The selection of personnel at universities is of great relevance. This dissertation deals with the selection processes of students, doctoral candidates, and postdocs and professors. The focus is on three elementary points of the processes: frequency of use, criterion validity, and acceptance. The work answers the questions of which procedures are used in the selection of personnel at universities, how well the success of students, doctoral candidates and postdocs, and professors can be predicted with different selection methods and how different selection methods in personnel selection procedures are accepted at universities. In two of our own studies, existing research gaps are closed, and the state of the literature is supplemented with new findings. For Study 1 N = 164 doctoral candidates were asked how they were selected. Doctoral positions were most often filled through unstructured selection interviews and personal contacts. N = 170 potential applicants for a doctoral position were asked about the acceptance ratings for selection procedures. Unstructured interviews, professional experience, work samples, and structured interviews had the highest ratings in acceptance. Study 2 focuses on the criterion validity and identified predictors that, in a longitudinal design, were able to predict both the objective and the subjective career success two years after completing the doctorate in N = 2 104 successful doctoral graduates. Two of the Big Five personality traits, openness to new experiences and neuroticism, were predictors for objective career success. Agreeableness and neuroticism could predict different aspects of subjective career success. In addition, a personality-requirement fit in openness to new experiences and extraversion was able to predict objective career success using response surface analysis.
