Tesis (magíster en derecho, con mención en derecho penal) / Actividad formativa equivalente a Tesis (AFET) / El tipo penal contemplado en el artículo 161 A del Código Penal protege la intimidad y sanciona conductas de intromisión. Las conductas de intromisón suponen la obtención ilícita de la información, obtención ilícita que pueden llevar a cabo tanto sujetos ajenos a una conversación como interlocutores de la misma. La obtención ilícita de información por parte de los interlocutores se materializará a través de engaños idóneos y determinantes. Los delitos contemplados en la disposición en estudio se cometerán cuando se ejecute una conducta de intromisión y, además, se ejecuten los verbos rectores tipificados. La sentencia de la Corte Suprema, dictada en el denominado “Caso de la Doctora Cordero”, es polémica porque albsuelve a los interlocutores que grabaron subrepticiamente a la afectada. La polémica surge porque parte de la doctrina entiende que el tipo penal sanciona a los que realicen meras grabaciones subrepticias, no siendo necesario que la conducta sea de intromisión, planteamiento del cual en el presente trabajo se discrepa.

Urban green spaces are one of the layers of urban pattern. The urban environment is created through the complex relationships between natural, social, economic, and politic dynamics. Similar to the urban environment, as a produced landscape, characteristics of urban green spaces vary according to the social, economic, cultural and ecological context of urban society. In the last few decades, the &ldquo / quality of urban life target&rdquo / included in the sustainability approach, has became an important touchstone to increase the quality of urban environment in today&rsquo / s world / with its tendencies of covering of perpetual subjective values and in addition to objective conditions to identify &ldquo / individual&rsquo / s satisfaction&rdquo / as a target the by, of keeping its evaluation scope broad and holistic, and of deriving supporting the daily life practices which derive from participatory processes. Among the quality of life perspective, urban green spaces are interpretated in a holistic and broad framework in boundaries of their contributions to the inhabitants&rsquo / well-being through their physical, social, economic and ecological links with life in a broad scale spectrum ranging from individual level to city scale. In today&rsquo / s urban environment, Ankara&rsquo / s urban green spaces are planned by the responsible agents within a narrow framework / separated from urban and urban life, lacked of this multi-scale and multi-dimensional perspective, stucked in the sectoral targets of institutions. At this point, the study identifies the priorities and conditions to re-establish a well-functioned planning process for the green spaces of Ankara with a particular attention to quality of life.

Hexagonal boron nitride (h-BN) formation by carbothermic reduction of B2O3 under nitrogen atmosphere at 1500&deg / C and effect of CaO addition into the initial B2O3 &amp / #8211 / active C mixture were investigated during this study. Reaction products were characterized by powder X-ray diffraction, scanning electron microscopy (SEM) and quantitative chemical analysis. Main aim of this study was to investigate the presence of a second reaction mechanism that catalytically affects h-BN formation during CaO or CaCO3 addition into the initial mixture. It was found that similar to CaCO3 addition, CaO addition has a catalytic effect on carbothermic formation h-BN. In order to investigate the reaction mechanism experiments with B2O3 &amp / #8211 / CaO mixtures without active carbon addition into the mixture were conducted. Furthermore nucleation of h-BN from calcium borate melts had been investigated and experiments were conducted with h-BN addition into CaO &amp / #8211 / B2O3 mixtures. It was concluded that nucleation of h-BN in calcium borate slags under experimental conditions is not possible. Hexagonal BN should be present in the system in order to activate the second nitrogen dissolution followed by h-BN precipitation mechanism. Highest efficiency was achieved in the experiment conducted with CaCO3 addition and largest particle size was observed during the experiment conducted to investigate the effect of nucleation.

The purpose of this study is to evaluate eighth grade students&rsquo / environmental literacy (knowledge, attitude, sensitivity and concern) level and to assess effects of socio-demographic variables (gender, parents&rsquo / educational level, parents&rsquo / work status and source of information about environmental knowledge) on their environmental literacy level. A total of 437 (212 girls and 225 boys) eight grade public school students are administered Environmental Literacy Test which includes four parts / knowledge (20 items), attitude (10 items), sensitivity (19 items), concern (12 items). Descriptive analysis showed that students have positive attitude and high degrees of concern and sensitivity toward environment / however they have low to moderate levels of environmental knowledge. In order to evaluate the role of socio-demographic variables on students&rsquo / environmental literacy level, six separate one-way MANOVAs were conducted. The results revealed that / a) there is significant effect of gender on students&rsquo / environmental literacy regarding to concern, in favor of girls, b) there is a significant effect of parents&rsquo / educational level on students&rsquo / environmental literacy / c) there is a significant effect of mothers&rsquo / work status on students&rsquo / environmental literacy and d) there is not a significant effect of source of information about environment on students&rsquo / environmental literacy.

Nanomaterials are widely investigated by researches and because of their unique properties they have been utilized in many different devices. Nanowires are one of these materials which show deviated mechanical, chemical, physical and optical, properties from their bulk counterparts. These deviations in properties of the nanowires are based on both their high surface to volume ratio and quantum confinement effect. Lately optical properties of nanowires have received great attention as they also exhibit good light sensitivity. Germanium is a semiconductor, which has been used widely as an active material in infrared light detectors. Due to excellent light detection of germanium its nanostructures have also been widely studied in optoelectronic devices. Germanium nanowires have been used in many devices such as field effect transistors, diodes, field emitters and photodetectors. Synthesis of high quality and high aspect ratio germanium nanowires could make important contributions to these devices. There are several synthesis methods for germanium nanowires. These are electrochemical etching, solvothermal, supercritical v fluidic, laser ablation, chemical vapor deposition and vapor transport methods. Among these methods, high quality, single crystalline, defect free germanium nanowires using accessible solid powder precursors could be synthesized with vapor transport method. In the first part of this thesis, germanium nanowire growth with vapor transport method is investigated. One of the most advantageous features of this method is using solid powder precursors instead of toxic gases. Until now, three different kinds of solid germanium precursors have been reported in vapor transport method, all of them are investigated and the resulting nanowires are compared in this thesis. Vapor transport method enables high control over the morphology of the nanowires. The most important parameters which affect the morphology of the nanowires are temperature, pressure and precursor type. Therefore, a detailed parametric study is provided based on these parameters and their effect on the final diameter of the nanowires is determined. The as &ndash / synthesized nanowires contain a very thick oxide layer on their surface. Therefore, oxide removal with acid etching is also investigated in this thesis. In the second part of this thesis, utilization of the germanium nanowire networks in fully transparent, flexible and network enhanced photodetectors is investigated. In order to obtain a germanium nanowire network, the as-synthesized nanowires are transferred from growth substrate to the device substrate by sonication and vacuum filtration. Silver nanowires and single walled carbon nanotubes are used as fully transparent electrodes. Both rigid and flexible photodetectors are fabricated and their current-voltage characteristics and photoresponse behaviors with different germanium nanowire densities are determined.

This study examines the making of the European identity concept under the impact of the European Union (EU) project. In order to define the structure of the European identity, theoretical and historical aspects have been scrutinised. Besides, the Eurobarometers (EBs) have been used to analyse the condition of European identity perception among the people of the member countries. The results of the EBs data show that the popularisation of the European identity is limited and the elite character of this identity seems dominant. The EU still lacks its common political identity, which forms a political agenda, and a supranational political identity. This thesis has concluded that the popularisation of the European identity can ensure more political unity for the EU, and this unity can be realised only with a multiple identity perception including current strong identities of the Europe.

Die Psychologie und andere empirische Wissenschaften befinden sich in einer Krise, da vielen Forschenden bewusst geworden ist, dass viele Erkenntnisse nicht so stark empirisch gestützt sind, wie sie einst glaubten. Es wurden mehrere Ursachen dieser Krise vorgeschlagen: Missbrauch statistischer Methoden, soziologische Verzerrungen und schwache Theorien. In dieser Dissertation gehe ich davon aus, dass ungenaue Theorien unvermeidlich sind, diese aber mithilfe von Induktion einer empirischen Prüfung unterzogen werden können. Anhand von Daten können Theorien ergänzt werden, sodass präzise Vorhersagen möglich sind, die sich mit der Realität vergleichen lassen. Eine solche Strategie ist jedoch mit Kosten verbunden. Induktion ist daher zwar notwendig, aber führt zu einem übermäßigen Vertrauen in empirische Befunde. Um empirische Ergebnisse adäquat zu bewerten, muss diese Verzerrung berücksichtigt werden. Das Ausmaß der Verzerrung hängt von den Eigenschaften des induktiven Prozesses ab. Einige induktive Prozesse können vollständig transparent gemacht werden, sodass ihre Verzerrung angemessen berücksichtigt werden kann. Ich zeige, dass dies bei Induktion der Fall ist, die beliebig mit anderen Daten wiederholt werden kann, was die Bedeutung von computergestützter Reproduzierbarkeit unterstreicht. Induktion, die die Forschenden und ihr kognitives Modell einbezieht, kann nicht beliebig wiederholt werden; daher kann die Verzerrung durch Induktion nur mit Unsicherheit beurteilt werden. Ich schlage vor, dass die Verringerung dieser Unsicherheit das Ziel von Präregistrierung sein sollte. Nachdem ich die Ziele von Reproduzierbarkeit und Präregistrierung unter dem Gesichtspunkt der Transparenz über Induktion präzisiert habe, gebe ich in den wissenschaftlichen Artikeln, die als Teil der Dissertation veröffentlicht wurden, Empfehlungen für die praktische Umsetzung beider Verfahren. / Psychology and other empirical sciences are in the middle of a crisis, as many researchers have become aware that many findings do not have as much empirical support as they once believed. Several causes of this crisis have been suggested: misuse of statistical methods, sociological biases, and weak theories. This dissertation proposes the following rationale: to some extent, imprecise theories are unavoidable, but they still can be subjected to an empirical test by employing induction. Data may be used to amend theories, allowing precise predictions that can be compared to reality. However, such a strategy comes at a cost. While induction is necessary, it causes overconfidence in empirical findings. When assessing findings, this overconfidence must be taken into account. The extent of the overconfidence depends on the properties of the inductive process. Some inductive processes can be made fully transparent, so their bias can be accounted for appropriately. I show that this is the case for induction that can be repeated at will on other data, highlighting the importance of computational reproducibility. Induction involving the researcher and their cognitive model can not be repeated; hence, the extent of overconfidence must be judged with uncertainty. I propose that reducing this uncertainty should be the objective of preregistration. Having explicated the goals of computational reproducibility and preregistration from a perspective of transparency about induction in the synopsis, I put forward recommendations for the practice of both in the articles published as part of this dissertation.

This dissertation investigates the economic consequences from hedge accounting signals and risk management disclosure. I first examine the product market consequences to these accounting signals and related disclosure in Chapter 1, then stock market reactions to disclosure requirements in Chapter 2. Chapter 1 examines potential entrants’ strategic entry decisions in response to incumbents’ accounting information and related disclosure. I predict that potential entrants are more likely to enter markets in which the incumbents’ accounting information suggests higher future production costs that are specific to the incumbents themselves. I further hypothesize that the relation is stronger when the accounting signals are accompanied by more disclosure. Using detailed U.S. airline industry data and hedge accounting disclosure under SFAS 133, I find that potential entrants are more likely to enter routes in which the incumbents’ lower accumulated other comprehensive income from fuel hedges suggests their higher future production costs. This entry pattern is stronger when incumbents have more transparent annual report disclosure regarding their fuel hedge programs. The entry pattern is also stronger after a systematic increase in risk management disclosure requirements following the (exogenous) adoption of SFAS 161. Chapter 2 analyzes stock returns of U.S. airlines around events leading up to the adoption of SFAS 161. SFAS 161 enhanced the disclosure requirements for derivatives and hedging activities. I find that U.S. airlines experienced statistically significant positive returns around the key events leading up to the adoption of SFAS 161. I then examine the cross-sectional variation of the returns around these events. Regression results provide initial support for the real effects theory that greater disclosure requirements could distort firms’ hedging and production decisions and lead to suboptimal behavior. In summary, this dissertation provides evidence that competitors use hedge accounting signals and related disclosure in making product market decisions. Meanwhile, additional risk-management disclosures may also distort firms’ hedging and production behavior, leading to suboptimal decisions. This dissertation sheds light on the ongoing projects by the FASB and the IASB on hedge accounting and disclosure and informs the regulators that costs and benefits should be weighted in hedge accounting policy setting.
