Syftet med studien var att undersöka hur en organisation kan skapa förutsättningar som underlättar för processägaren i samband med implementering av processledning. För att uppfylla syftet har studien försökt besvara frågeställningarna gällande vem som bör utsestill processägare och vilket ansvar och vilka uppgifter som ska läggas på processägaren. I studien har olika teorier och fallstudier analyserats mot ett företag som precis påbörjat sitt arbetemed processer. Intervjuer och dokument tillhandahållna ur det studerade företagets ledningssystem har använts för insamling av data. Analysen har skett med kategorier som författaren själv skapat. Dessa kategorier kan även användas för att analysera andra organisationer i liknande situation. Resultatet av studien visar att processägaren bör vara någon som förstått och förespråkar processtänket och med förmåga och formell befogenhet att genomdriva förbättringar. Kombinerar processägaren sin roll med rollen som linjechef är det viktigt att denne ser till processens bästa, även om det sker till bekostnad av den ”egna” avdelningen.  Resultatet visar också att organisationen bör etablera stödjande roller till processägaren, tydliggöra ansvaret samt fördela ut uppgifterna på de olika rollerna. Rollerna och fördelningen kan se olika ut för olika processer inom samma organisation, beroende på processens karaktär. Trots att de fördelade uppgifterna är många, är de nödvändiga för att täcka alla de delar som är fundamentala för processägarens organisation. / The purpose of this study is to examine how an organization can create a favourable environment for implementing a process management from the perspective of the process owner. The study has been conducted based on the following questions: Who should be appointed as process owner? What responsibility and tasks should be assigned to said process owner? The study compares various theories and case studies to a company that has just begun implementing a process management. The data that the study is based on consists of interviews and documents provided from the studied company's management system. The result of the study indicate that the process owner should be someone who understands and advocates in favor of process thinking as well as someone who has the ability and formal authority to drive improvements. The result also shows that if the process owner is confronted with a conflict of interest between their own department and the process, it is important that they rule in favor of the process. It is also made apparent that the organization should establish supporting roles for the process owner and distribute the tasks between them. It is important to note that the establishment of roles and delegation of tasks may look different depending on the nature of the process. Although the distributed tasks are many, they are necessary to cover all the elements that are fundamental to the process owner's organization.

The study aims to increase the knowledge of the extent to which primary school teachers use problem solving tasks to challenge and include mathematically gifted pupils. Furthermore, it aims to increase knowledge about the factors that influence teachers´ design around these tasks. The work is based on a quantitative survey among primary school teachers who teach mathematics. 104 teachers were included in the study group, where 96 percent had competence in teaching mathematics for compulsory school grades 1-3. The study clarifies what characterizes gifted pupils and how these features can be noticed in mathematics education. Furthermore, the teacher’s theoretical and didactic competence in mathematics is central to developing and shaping learning opportunities containing problem-solving tasks, which are well adapted to challenge and include gifted pupils. The study's overall theoretical approach is based on a cognitive theory and the result was analyzed with the help of the Mathematics Tasks Framework. The result shows that the majority of the lower-level teachers, who were part of the selection group, believe that problem solving tasks are advantageous to apply in order to include and challenge gifted pupils. However, teachers feel that they are facing obstacles in the work of giving gifted pupils the opportunity to learn, both in the planning phase and in the implementation phase. Teachers admit that they need to improve their competence in order to be able to challenge and include gifted pupils in mathematics education. / Syftet med studien är att öka kunskapen om i vilken utsträckning lågstadielärare använder problemlösningsuppgifter för att utmana och inkludera särskilt begåvade elever.  Vidare syftar den till att öka kunskapen om vilka faktorer som påverkar lärares utformning av problemlösningsuppgifter. Arbetet är baserat på en kvantitativ enkätundersökning som riktar sig till matematiklärare på lågstadiet. 104 lågstadielärare ingick i undersökningsgruppen, där 96 procent hade behörighet att undervisa i ämnet matematik för grundskolans årskurs 1–3. Studien belyser vad som karaktäriserar särskilt begåvade elever samt hur dessa drag kan uppmärksammas i matematikundervisningen. Studien tar utgångspunkt i att lärarens ämnesteoretiska och ämnesdidaktiska kompetens står i centrum när lärare utvecklar och formar lärtillfällen innehållande problemlösningsuppgifter, vilka är väl anpassade för att utmana och inkludera särskilt begåvade elever. Studiens övergripande teoretiska ansats utgår från en kognitivistisk teori och resultatet analyserades med hjälp av ramverket Mathematics Tasks Framework. Av resultatet framkommer att majoriteten av de lågstadielärare som ingick i urvalsgruppen anser att problemlösningsuppgifter är fördelaktiga att tillämpa för att inkludera och utmana särskilt begåvade elever. Lärarna upplever dock vissa hinder i arbetet med att ge särskilt begåvade elever möjligheten att lära, både i planeringsfasen och i genomförandefasen. Majoriteten av lärarna medger att de är i behov av kompetensutveckling för att ha förmågan att utmana och inkludera särskilt begåvade elever i matematikundervisningen.

The overall purpose of the study is partly to increase knowledge about the use of open mathematics by primary school teachers, and partly if the tasks are considered functional to use to include high-performing students in mathematics education. In order to achieve the purpose of the study, an internet survey was constructed. Through the survey, data were collected from 104 active primary school teachers who teach mathematics in Sweden. The results show that a large part of the teachers who participated in the study use open mathematical tasks in the teaching. In addition, more than half of the respondents considered that the tasks could be used to include high-performing students in the heterogeneous classroom. The study suggests that professional development among primary school teachers is needed to enable an improvement in the ability to work with open mathematical tasks and the inclusion of high-performing students. / Det övergripande syftet med studien är dels att öka kunskapen om lågstadielärares användning av öppna matematiska uppgifter, dels om sådana uppgifter anses funktionella att använda för att inkludera högpresterande elever i matematikundervisningen. För att uppnå syftet med studien konstruerades en internetenkät. Via enkäten samlades data in från 104 verksamma lågstadielärare som undervisar i matematik runt om i Sverige. Resultaten visar att en stor del av de lågstadielärare som deltog i studien använder öppna matematiska uppgifter i undervisningen. Dessutom ansåg drygt hälften av respondenterna att nämnda uppgifter kunde användas för att inkludera högpresterande elever i det heterogena klassrummet. Studien antyder att det behövs kompetensutveckling bland lågstadielärare för att möjliggöra en förbättring av förmågan att arbeta med öppna matematiska uppgifter samt inkludering av högpresterande elever.

<p>Persistent and maladaptive fear in the absence of a threat can be disruptive because it decreases an organism’s opportunity to seek life-sustaining substances. Learned safety signaling can suppress fear and encourage reward-seeking behavior, thus freeing the organism from fear induced immobilization. The infralimbic (IL) region of the prefrontal cortex is important for recalling fear extinction memories and for suppressing fear via learned safety signals. Neurons in the IL show an excitatory response to an extinguished fear cue. We thus hypothesized that neurons in the IL would encode safety by showing an excitatory response during active fear suppression to a learned safety signal. </p> <p>To assess global changes in IL activity, we monitored IL multi-unit activity to different cues while training animals in a fear-reward-safety discrimination task (Sangha, Chadick, & Janak, 2013). During the discrimination task, male rats learned that the reward cue predicted liquid sucrose, the fear cue predicted footshock and the joint presentation of both the fear and safety cues resulted in no footshock. We also counterbalanced the modality of fear and safety cues (auditory vs visual) with two separate groups of animals to control for potential sensory modality effects. Male rats showed high levels of freezing to the fear cue, and significantly reduced levels of freezing to the combined fear+safety cue. Male rats also showed high levels of port activity to the reward cue. There was no significant difference in the learning rate between the two counterbalanced conditions. </p> <p>Our multi-unit-data showed an increase in IL neuronal firing to the fear+safety cue across training sessions. This effect was consistent between the two counterbalanced conditions. We also examined single-unit activity from all animals that received light as the safety cue (n=8). This allowed us to examine the population response profile with a subset of the total animals. Although not statistically significant, our preliminary single-unit data demonstrated a decrease in the percentage of neurons that showed an inhibitory response to the fear+safety cue, but no change in the percentage of neurons that showed an excitatory response to the fear+safety cue. There was also no change in the magnitude of averaged firing rate in fear+safety excitatory or inhibitory neurons across training. Taken together, the decreased inhibition of single-unit activity in the IL may drive the increased excitation in multi-unit activity in the IL during behavioral fear suppression to a safety signal. </p>

7 SUMMARY This thesis is divided into two separate portions. The first part covers my own lichen floristic exploration of the Károvské údolí locality stretching out along the southern limits of Prague near Zbraslav. The location is formed by relatively steep slopes with orientation to North and South. Natural conditions are characterised by communities of xerothermic steppes and oak groves with alder clumps and hornbeams prevailing in lower parts along the Károvský potok stream. Geologically, the parent rock consists of shale rocks of acid chemical composition. Duting my search, I recorded 116 lichen species. Among them, saxicolous and terricolous lichens characteristic of acid rock outcrops and xerotherm steppes prevail. During exploration, I found also the critically endangered (CR) species Peltigera elisabethae, endangered species (EN) Flavoparmelia caperata and representatives of the genus Verrucaria, tolerant of long-term freshwater flooding - V. cf. andesiatica, V. aquatilis and V. funckii. One of species discovered, Pertusaria flavicans, has not been recorded in the Czech Republic todate. This locality is home to a summer house resort which has expanded the list of lichens by basophilic species which inhabit anthropogenic substrata. My master thesis is the first thorough research of the lichen flora...

In the thesis, results of a research focused on monitoring strategies used by students during problem solving are presented. It follows previous studies conducted with the use of think- aloud method. Due to limitations of this method, an eye-camera is used. The record of the camera is used not only to analyse student's problem-solving process, but also as a tool eliminating one of the RTA limits - inaccuracies due to forgetting. The strategies were investigated among economics-oriented vocational school students in the first grade. They solved indicator tasks from the Methodical Comments and Tasks for Educational Standards in Lower-Secondary Education. The research sample was selected based on a pre-test composed of the selected tasks. According to the results, the students were divided into four categories, two students of each category were selected for the research. They solved a second set of the tasks. Based on eye-tracking and think-aloud data, their problem- solving processes were mapped and false-positive results were eliminated. The research results show that the students used the most expansive strategies, mainly work with the periodical table. However, in most cases, these strategies did not lead to a correct solution, due to the students' problems during solving. In these cases, they...

Denna studie syftar till att undersöka hur problemlösningsuppgifter i läromedel som är vanliga i svensk skola bidrar till elevers matematiska utveckling inom området problemlösning. Ett analysverktyg har konstruerats och använts till att genomföra en analys av problemlösningsuppgifterna i de båda läroböckerna. Slutsatser som framkommit är att läraren i mer eller mindre grad måste kompensera så att uppgifterna uppfyller alla kriterier och att lärare måste vara särskilt uppmärksamma på att ge elever möjligheter att implementera och att tillägna sig problemlösningsstrategier samt utmanas att reflektera och verifiera sina lösningar. / This study aims to investigate how problem-solving tasks in educational books that are common I Swedish schools contribute to student’s development in mathematics in the area of problem-solving. A framework has been created and used to conduct an analysis of the problem-solving tasks in two educational books. The conclusions are that the teacher more or less needs to compensate for some aspects of the problem-solving tasks and that the teacher has to be extra careful to make sure that the students will appropriate problem-solving strategies and reflect upon and verify their solutions.

The thesis describes an investigation into Air Traffic Control (ATC) complexity as a contributory factor in changes of controllers' workload. It is considered that ATC complexity, together with equipment interface and procedural demands comprise the task demands imposed on the en-route controller to perform certain activities, which mediated by performance shaping factors create workload. The data used to study this relationship came from ATC real-time simulations completed at EUROCONTROL CRDS in Budapest: recorded flown trajectories, communication performed by the controller (whether with other controllers or with the pilots), data entries related to flight data management, and instantaneous self-assessment ratings of workload provided by the controllers were used. The ATC complexity factors that have been consistently found to be important in the previous studies (related to aircraft density, flight attributes of each individual aircraft, aircraft conflicts and traffic disorder) and for which detailed calculation formula have been reported were selected for further analysis. Since the established set of factors resulted from multiple researches conducted in this field, it was assumed that some of these factors are correlated with one another, overlapping and possibly measuring similar concepts. Therefore, a reduction of the initial set of factors was performed by combining information contained within these factors into a smaller number of new artificial variables and by deleting statistically redundant portions of these factors prior to conducting further analysis. The Principal Component Analysis (PCA), which is the statistical method applied to achieve required reduction, resulted in the overall set of 6 complexity components, whose interpretations are driven by the factors that showed the strongest correlation with that component. In order to establish a link between ATC complexity and a controller's subjective workload, multiple regression analysis was performed, using the complexity components identified in the PCA as predictors of the workload ratings. In addition, some measures of controller’s activity (data entries made by the controllers related to flight data management, cumulative duration of radio calls, i.e. frequency occupancy time, and average duration of single calls) were added to the analysis to test whether information about the controller’s activity could be also useful for predicting workload, once the effect of complexity had been considered, and to verify whether the effect of complexity on workload could be mediated by the effect of complexity on the controller’s activity. The analysis revealed that both ATC complexity and the activities that the controller performs to deal with a demand imposed on him/her give a unique contribution to the prediction of workload ratings and therefore the workload of the controller is determined by both ATC complexity and controller’s activities. In addition, it was assumed that the workload is differently impacted by individual components of complexity, and further statistical analyses were performed to test this assumption. Understanding these differences could in fact facilitate comparison of the complexity levels of a single sector under different conditions, but also comparison of complexity levels of different sectors under same conditions. Firstly the changes in the workload and activities of the controllers under different conditions were investigated using analysis of variance. Subsequently, in order to be able to map these changes on the complexity components, it was necessary also to investigate into the changes that the complexity components undergo when observed under different conditions. The results revealed different behaviour of single complexity components when mapped on the changes recorded in the activities of the controller and workload, demonstrating that changes in controller’s activities and perceived workload are driven by different complexity components in different sectors and under different operational conditions. Shedding light on these contributors to the workload experienced by a controller can greatly facilitate the introduction of any change envisaged for the airspace under consideration. Namely, in the current structure, whenever new procedures or new working methods are subject to possible deployment, the identified complexity components could support the estimation of the impact that those changes would impose on the workload of the controller and further on decision making processes. Additionally, the complexity components are also applicable in the validation of the new concepts and new technologies to be introduced in the system when designing simulation scenarios against which new concepts would be assessed. As also demonstrated by the analysis, the comparison of different sectors, or even different sector designs within the same airspace, could be compared and contribute to the improvement of airspace design. / Die vorliegende Arbeit untersucht die Komplexität der Flugverkehrskontrolle (Air Traffic Control, ATC) als einen wesentlichen Einflussfaktor auf die Arbeitsbelastung des Radarlotsen. Die zentrale Annahme ist dabei, dass die Komplexität der ATC zusammen mit den Anforderungen aus den betrieblichen Rahmenbedingungen (technische Systemschnittstellen und Prozeduren) den Lotsen zu bestimmten Abläufen zwingen, welche die Arbeitsbelastung signifikant beeinflussen. Für die durchgeführten Untersuchungen standen Daten von ATC-Echtzeitsimulationen von EUROCONTROL CRDS Budapest zur Verfügung, die folgende Informationen umfassen: abgeflogene Flugtrajektorien, Kommunikationsprotokolle der Lotsen (untereinander oder zwischen Lotse und Pilot), Daten aus dem flight-data Management und Daten aus der regelmäßigen Selbstbewertung der Lotsen bezüglich ihrer aktuell gefühlten Arbeitsbelastung. Die bereits in früheren Studien identifizierten Komplexitätsvariablen (insbesondere die lokale Flugzeugdichte, spezifische Flugzeugeigenschaften, Konfliktsituationen zwischen Flugzeugen und die Verkehrslage betreffend) sowie hierzu erarbeitete mathematische Vorschriften bilden die Grundlage für die weiterführenden, detaillierten Untersuchungen. Aufgrund der Vielzahl an Komplexitätsvariablen aus diversen wissenschaftlichen Quellen war davon auszugehen, dass Korrelationen unter den Variablen vorliegen. Aus diesem Grund wurden zunächst statistisch redundante Informationen der ursprünglich vorliegenden Variablen reduziert, sodass als Ergebnis neue voneinander unabhängige Faktoren klassifiziert werden konnten. Die hierfür verwendete Hauptkomponentenanalyse (Principal Component Analysis - PCA) führte zu sechs statistisch signifikanten Komplexitätsfaktoren, die anhand der höchsten Korrelation zur zugeordneten Komponente interpretiert wurden. Um die Verbindung zwischen der ATC Komplexität und der subjektiv empfundenen Arbeitsbelastung herzustellen, wurde eine multiple Regressionsanalyse zwischen den Komplexitätsfaktoren und den abgeleiteten Arbeitsbelastungszuständen durchgeführt. Zusätzlich lagen für die Analyse der Arbeitsbelastung auch Daten über die Arbeitsaufgaben des Lotsen vor (bspw. Dateneinträge des Lotsen, Gesamtlänge der Funkanweisungen, durchschnittliche Länge der Funkanweisungen), um zu untersuchen, inwieweit sich aus den aktuell durchgeführten Arbeitsaufgaben bei gegebener Verkehrsnachfrage eine verlässliche Vorhersage über die Arbeitsbelastung ableiten lässt. Die Analyse zur Vorhersage der Arbeitsbelastung konnte zeigen, dass sowohl die ATC Komplexität als auch die aktuellen Arbeitsaufgaben einen individuellen und signifikanten Einfluss haben. Weiterhin wurde unterstellt, dass die spezifischen Komplexitätsfaktoren einen unterschiedlichen Effekt auf die Arbeitsbelastung ausüben. Die Überprüfung dieser Annahme war ebenfalls Bestandteil der umfangreichen statistischen Untersuchungen. Tatsächlich könnte ein fundamentales Verständnis der Komplexitätsgrade den Vergleich einzelner Luftraumsektoren unter verschiedenen operativen Randbedingungen, als auch den Vergleich unterschiedlicher Luftraumsektoren mit vergleichbaren operativen Randbedingungen wesentlich erleichtern. Zuerst wurden die Veränderungen der Arbeitsbelastung und -die Tätigkeiten der Lotsen unter Verwendung einer Varianzanalyse untersucht. Um eine valide Zuordnung zu den Komplexitätsfaktoren sicherzustellen, war es ebenfalls notwendig, die Veränderungen dieser Faktoren und Tätigkeiten unter wechselnden Randbedingungen zu analysieren. Die Analysen zeigen hierbei unterschiedliche Resultate bezüglich der jeweiligen Komplexitätsfaktoren. So beeinflussen die verschiedenen Komplexitätsfaktoren die Handlungsabläufe der Lotsen und die wahrgenommene Arbeitsbelastung, jedoch in Abhängigkeit von den ausgewählten Sektoren und den betrieblichen Randbedingungen. Unter Berücksichtigung dieser erarbeiteten Abhängigkeiten der Arbeitsbelastung des Lotsen können nun die Auswirkungen von Veränderungen im Luftraum zuverlässig bestimmt werden. Gerade in Bezug auf Veränderungen der gegenwärtigen Luftraumstruktur oder die Einführung neuer Prozeduren oder Arbeitsabläufe können die entwickelten Komplexitätsfaktoren bereits frühzeitig Aufschluss darüber geben, welche Konsequenzen solche Veränderungen auf die Arbeitsbelastung der Lotsen nach sich ziehen können und Entscheidungsprozesse unterstützen. Weiterhin sind die entwickelten Komplexitätsfaktoren als Grundlage für die Validierung neuer Konzepte und Technologien, gegebenenfalls unter Verwendung von entwickelten Simulationsszenarien, nutzbar. Darüber hinaus können die Komplexitätsfaktoren für die Gegenüberstellung von verschiedenen Luftraumsektoren genutzt werden und zur Abwägung bzw. Optimierung von Entwürfen eines Luftraumdesigns dienen.
