This thesis focuses on the initial validation of the PTSD Checklist for DSM-5 (PCL-5) in its Czech version. It is a self-report method that measures symptoms accompanying posttraumatic stress disorder (PTSD). The theoretical part of the thesis describes the development of the diagnosis of PTSD over time and its current criteria. It also presents a list of diagnostic tools for measuring PTSD, including the PCL-5 and its psychometric properties. The research part of the thesis describes the process of data collection and processing, the results of the hypotheses and discussion. The research sample consisted of 444 respondents (370 women; 74 men) with a mean age of 32,6 years (SD = 10,6). The mean PCL-5 score was 29,3 (SD = 19,9). When comparing the scores of women (M = 30,2; SD = 20) and men (M = 24,7; SD = 18,8), a statistically significant difference was observed (p = 0,029). When comparing respondents who were psychiatric patients (PP; M = 39,5; SD = 20) and those who were not (M = 21,7; SD = 16,6), a significant difference (p < 0,001) was also observed. In case of comparison of respondents by gender who were not PP, no statistically significant difference was confirmed. Cronbach's alpha for the whole questionnaire came out high: 0,955 (for clusters ranging from 0,831-0,908), which is consistent...

<p> </p> <p>As a result of Shadow NeRF and Sat-NeRF, it is possible to take the solar angle into account in a NeRF-based framework for rendering a scene from a novel viewpoint using satellite images for training. Our work extends those contributions and shows how one can make the renderings season-specific. Our main challenge was creating a Neural Radiance Field (NeRF) that could render seasonal features independently of viewing angle and solar angle</p> <p>while still being able to render shadows. We teach our network to render seasonal features by introducing one more input variable — time of the year. However, the small training datasets typical of satellite imagery can introduce ambiguities in cases where shadows are present in the same location for every image of a particular season. We add additional terms to the loss function to discourage the network from using seasonal features for accounting for shadows. We show the performance of our network on eight Areas of Interest containing images captured by the Maxar WorldView-3 satellite. This evaluation includes tests measuring the ability of our framework to accurately render novel views, generate height maps, predict shadows, and specify seasonal features independently from shadows. Our ablation</p> <p>studies justify the choices made for network design parameters. Also included in this work is a novel approach to space carving which merges multiple features and consistency metrics</p> <p>at different spatial scales to create higher quality digital surface map than is possible using standard RGB features.</p>

Adults with pedophilic interests are often viewed by the public as a homogenous subgroup based on what we know from those who sexually offend against children. The stigma associated with child sexual abuse may serve to deter such behaviors but may also interfere with the person’s stability and willingness to seek assistance in managing pedophilic interests. This article contrasts the sex offender response and prevention efforts typically employed in the U.S. (i.e., containment, registration, and notification policies and public education programs) with treatment programs aimed at preventing child sexual abuse in Germany, Belgium, and Canada. Five major areas are identified that should be further examined with regard to implementing preventative outreach and treatment programs in the U.S.: barriers to outreach and treatment programs, how to expand or reframe current preventative educational programs, implementation of such programs in light of current mandating reporting policies, promising treatment approaches for pedophilic interests among non-offenders, and ethical concerns relevant to preventative psychological interventions.

Aircraft design is an act of art requiring dedication and careful work to ensure good results. An essential tool in that work is a flight mechanics simulator. Such simulators are often built up of modules/models that are executed in a sequential order in each time iteration. This project aims to analyze potential improvements to the model execution order based on the dependency structure of one such simulator. The analysis method Design Structure Matrix (DSM), was used to define/map the dependencies and then Binary Linear Programming (BLP) was utilized to find five new potentially improved model orders to minimize the number of feedbacks from one iteration to the next one. Those five proposed execution orders were next compared and evaluated. The result is a model order that reduce the number of models receiving feedbacks from the previous iteration from 13 to 6, with insignificant changes in the precision of the simulator. / Vid flygplanskonstruktion krävs hårt och noggrant arbete för att säkerställa gott resultat. Ett oumbärligt verktyg är då en flygmekanisk simulator. Den typen av simulatorer är ofta uppbyggda av moduler/modeller som exekveras i en bestämd sekventiellt ordning i varje tidsteg. Syftet med detta projekt är att undersöka möjliga förbättringar av exekverings ordningen av de olika modellerna i en existerande simulator, baserat på beroendestrukturen. Analysmetoden Design Structure Matrix (DSM) användes för att bestämma beroendestrukturen och sedan utnyttjades Binär Linjär Programmering (BLP) för att hitta fem förbättrade modellordningar med avseende på att minimera antalet modeller som erhåller indata från föregående tidsiteration. De fem förbättringsförslagen jämfördes och utvärderades. Resultatet är en modellordning som kan minska antalet återkopplande modeller från 13 till 6, med insignifikanta skillnader i precisionen av simulatorn.

Today, worldwide business communities are in the era of the Supply Chains. A Supply Chain is a collection of several independent enterprises that partner together to achieve specific goals. These enterprises may plan, source, produce, deliver, or transport materials to satisfy an immediate or projected market demand, and may provide the after sales support, warranty services, and returns. Each enterprise in the Supply Chain has roles and elements. The roles include supplier, customer, or carrier and the elements include functional units, processes, information, information resources, materials, objects, decisions, practices, and performance measures. Each enterprise, individually, manages these elements in addition to their flows, their interdependencies, and their complex interactions. Since a Supply Chain brings several enterprises together to complement each other to achieve a unified goal, the elements in each enterprise have to complement each other and have to be managed together as one unit to achieve the unified goal efficiently. Moreover, since there are a large number of elements to be defined and managed in a single enterprise, then the number of elements to be defined and managed when considering the whole Supply Chain is massive. The supply chain community is using the Supply Chain Operations Reference model (SCOR model) to define their supply chains. However, the SCOR model methodology is limited in defining the supply chain. The SCOR model defines the supply chain in terms of processes, performance metrics, and best practices. In fact, the supply chain community, SCOR users in particular, exerts massive effort to render an adequate supply chain definition that includes the other elements besides the elements covered in the SCOR model. Also, the SCOR model is delivered to the user in a document, which puts a tremendous burden on the user to use the model and makes it difficult to share the definition within the enterprise or across the supply chain. This research is directed towards overcoming the limitations and shortcomings of the current supply chain definition methodology. This research proposes a methodology and a tool that will enable an automated and comprehensive definition of the Supply Chain at any level of details. The proposed comprehensive definition methodology captures all the constituent parts of the Supply Chain at four different levels which are, the supply chain level, the enterprise level, the elements level, and the interaction level. At the Supply Chain level, the various enterprises that constitute the supply chain are defined. At the enterprise level, the enterprise elements are identified. At the enterprises' elements level, each element in the enterprise is explicitly defined. At the interaction level, the flows, interdependence, and interactions that exist between and within the other three levels are identified and defined. The methodology utilized several modeling techniques to generate generic explicit views and models that represents the four levels. The developed views and models were transformed to a series of questions and answers, where the questions correspond to what a view provides and the answers are the knowledge captured and generated from the view. The questions and answers were integrated to render a generic multi-view of the supply chain. The methodology and the multi-view were implemented in an ontology-based tool. The ontology includes sets of generic supply chain ontological components that represent the supply chain elements and a set of automated procedures that can be utilized to define a specific supply chain. A specific supply chain can be defined by re-using the generic components and customizing them to the supply chain specifics. The ontology-based tool was developed to function in the supply chain dynamic, information intensive, geographically dispersed, and heterogeneous environment. To that end, the tool was developed to be generic, sharable, automated, customizable, extensible, and scalable.

This paper presents DSM64: a lazy release consistent software distributed shared memory (SDSM) system built entirely in user-space. The DSM64 system is capable of executing threaded applications implemented with pthreads on a cluster of networked machines without any modifications to the target application. The DSM64 system features a centralized memory manager [1] built atop Hoard [2, 3]: a fast, scalable, and memory-efficient allocator for shared-memory multiprocessors. In my presentation, I present a SDSM system written in C++ for Linux operating systems. I discuss a straight-forward approach to implement SDSM systems in a Linux environment using system-provided tools and concepts avail- able entirely in user-space. I show that the SDSM system presented in this paper is capable of resolving page faults over a local area network in as little as 2 milliseconds. In my analysis, I present the following. I compare the performance characteristics of a matrix multiplication benchmark using various memory coherency models. I demonstrate that matrix multiplication benchmark using a LRC model performs orders of magnitude quicker than the same application using a stricter coherency model. I show the effect of coherency model on memory access patterns and memory contention. I compare the effects of different locking strategies on execution speed and memory access patterns. Lastly, I provide a comparison of the DSM64 system to a non-networked version using a system-provided allocator.

Copyright contractual law consist of rules that regulate contracts within copyright law. One of the main characteristics of copyright contracts is that they are often characterised by differences in bargaining power between the parties. The weak position of authors has therefore become the subject of mandatory legislation in various respects. Recently, Article 20 of the Directive (EU) 2019/790 (DSM-Directive) incorporated such a rule. This article provides authors with a right to additional, appropriate and fair remuneratiom after the conclusion of the contract if their remuneration proves to be disproportionately low. That is, a right to obtain post-contractual remuneration through mandatory legislation. It is in theory possible to also achieve similar results by applying Section 36 of the Swedish Contracts Act. This paper will examine both of these rules. This constitutes an interesting area of law, but the detailed applications of the rules are still understudied. This paper therefore aims to take a holistic approach to the possibility for authors to obtain additional post-contractual remuneration through mandatory legislation. The study identifies several problems and ambiguities in the application and proposes solutions to these issues. The conclusion was that the requirements for applying Article 20 are generally to be seen as lower than Section 36 of the Swedish Contracts Act, while in theory it should also lead to higher remuneration for authors. However, Section 36 of the Copyright Act can be applied to a wider range of cases and to some extent addresses other circumstances. The addition of article 20 has either way improved authors right to remuneration as well as bargaining power. However, some of the other issues that authors face during the contract negotiations were not solved through the directive.
