In recent years, technological developments have led to the emergence of 360°. Google Street Map has provided panoramic imagery for a number of years, where users can immerse themselves and pan around in scenarios and follow streets of their liking, familiarizing and navigating themselves with the location. However, this service supports neither video nor moving imagery. This paper explores the use of 360° panoramic videos as a navigation aid on two different platforms as well as consider more subjective perspectives from potential users. The study is conducted through a set of interviews and a focus group where the findings reveal a number of design challenges concerning the development of a navigational system based on 360° panoramic videos. Based on these findings, design challenges are presented and later summarized as three design recommendations; 1) Design for navigation in a panoramic scenery, 2) Support overview and traditional navigation, 3) Support custom tailored features and content. The studies also suggest that the use of a head-mounted display (HMD) increase the feeling of presence which is beneficial for navigational purposes however, the users in this study preferred the mobile device based on practicality.

In this thesis we study users' viewing motions when watching 360° videos in order to provide information that can be used to optimize future view-dependent streaming protocols. More specifically, we develop an application that plays a sequence of 360° videos on an Oculus Rift Head Mounted Display and records the orientation and rotation velocity of the headset during playback. The application is used during an extensive user study in order to collect more than 21 hours of viewing data which is then analysed to expose viewing patterns, useful for optimizing 360° streaming protocols.

The effectiveness of Sexual Offending Treatment programmes has generally been measured through evaluating intervention content and reoffending rates. In response to the growing call to explore the role of therapeutic process in facilitating meaningful change on these programmes, this thesis considers how interpersonal dynamics may influence programme effectiveness from the perspective of the group member. This offers the opportunity to consider the impact of how we work, rather than what we do. The critical literature review uses a pluralistic framework to present relevant existing research and identify gaps in practice-based knowledge in the field of sexual offending intervention from a Counselling Psychology perspective. While the literature suggests interpersonal ingredients important to this process, it offers little information regarding where, when and how these qualities are effective. Furthermore, little is understood about the impact of relational dynamics between the facilitators and group members in creating a facilitative environment. This reveals broad gaps in research relating to a neglect of the client’s experience of these interactions and how they are conceptualised in their change process. This research therefore uses a social constructivist grounded theory method to generate data exploring these process issues. The results highlight the value of facilitators fostering a dynamic and balanced core interpersonal process that is sensitive to the unique context of these group interventions. This offers a foundation for group member engagement and effective group functioning relevant to subjective change. The implications for theory and practice are discussed, highlighting how a Counselling Psychology presence in this field has the potential to enhance practice. The study is concluded with reflections of the study’s limitations and areas in need of further research.

Im Zuge der fortschreitenden Industrialisierung, besonders ab der Phase des Wiederaufbaues nach dem Zweiten Weltkrieg, wurde in Österreich eine große Zahl an neuen Industriebetrieben errichtet, vielfach in Großstädten oder knapp am Rand von derartigen Ballungszentren. Manche der angesiedelten Betriebsanlagen wurden für die Lagerung und Produktion großer Mengen an entzündlichen, giftigen oder anderweitig gefährlichen Stoffen genützt. Durch den regen Zuzug von Arbeitssuchenden aus dem ländlichen Raum in die Großstädte war eine stetig Einwohner- und flächenmäßig wachsende Ausdehnung der Großstädte die Folge. Der städtische Wohnbau förderte eine teilweise Umsiedelung sowie ein Heranrücken von gewerblichen oder industriellen Betriebsanlagen an die Ballungszentren. Mehrere große Industrieunfälle in der zweiten Hälfte des zwanzigsten Jahrhunderts mit hohen Schädigungsausmaßen an Mensch und Umwelt, besonders im Zusammenhang mit gefährlichen Stoffen, führten zu einem Umdenken in Gesellschaft und Politik. Die Diskussionen über gesetzliche Mindeststandards zur Verbesserung des Risikomanagements zwecks Minimierung von Gefährdungspotenzialen und die Konflikte über die Standortfrage von gefahrengeneigten Betriebsanlagen in derartigen Ballungsräumen begannen größere Dimensionen anzunehmen. Immer wieder tauchte dabei in der Diskussion die Frage auf, welche monetären Schadenseinflüsse die Nähe solcher Betriebe für die umgebende Bevölkerung verursachen können. In dieser Dissertation wird dieser Aspekt näher beleuchtet und anhand eines konkreten Falles ein sozioökonomischer Bewertungsversuch des möglichen Einflusses von Gefährdungspotenzialen aus gefahrengeneigten Betriebsanlagen (so genannte "Seveso-Betriebsanlagen") auf regionale Immobilienpreise unternommen. Es wird erwartet, dass auf der Basis empirisch ermittelter Daten eine Aussage über den Grad einer allfälligen Einflussnahme gemacht werden kann.

Performance improvement intervention begins with assessment. How that assessment is interpreted can mean the difference between success and failure. Previous research of 360-degree feedback instruments has tried to reconcile the differences between multiple rater groups. Rather than searching for agreement, this research proposes to understand the meaning of the differences using multirater feedback. Individuals determine ratings based upon their own perspective and building upon the understanding of rater perspective may result in improved assessments. Data from an existing data set was processed using a second-order CFA in structural equation modeling. Covariance between the second-order factors and rater groups determined the difference in how each rater group perceived the leader.

El presente trabajo de suficiencia profesional, se realizó en base a la información obtenida de la empresa Josfel Iluminación SAC, la cual no contaba con un modelo de gestión por competencias aplicado dentro de la organización. El objetivo general fue generar una propuesta de implantación de un modelo de competencias de liderazgo para los mandos medios y superiores. Se utilizó el método descriptivo con una población de 33 colaboradores, las herramientas técnicas utilizadas fueron entrevistas a profundidad y evaluación 360°, esta evaluación fue elaborada en base a la metodología de Martha Alles, especialista en investigar y desarrollar temas sobre recursos humanos, comportamiento organizacional y gestión por competencias dentro de las organizaciones. A través de las evaluaciones 360°, obtuvimos que existen competencias como visión estratégica y sistémica, y empowerment, que no están tan desarrolladas, mientras que otras como dirección de equipos y entrenador, fueron bien valoradas y se encuentran en buen nivel de desarrollo. En base a la metodología aplicada, se recomendó que a partir de las brechas encontradas luego del análisis, se trabaje e implemente en el área de Recursos Humanos la gestión por competencias enfocadas en el liderazgo. Esto se concluyó debido a que el liderazgo es una competencia clave que tiene que tener cada puesto de trabajo dentro de Josfel Iluminación SAC por lo que se recomendó modificaciones en sus procesos de reclutamiento, selección, desarrollo y evaluación. / The present work of professional sufficiency was made based on the information obtained from Josfel Iluminación SAC Company, which did not have a competency management model applied at the organization. The main objective was to generate an implementation proposal for leadership competences model for middle and senior position. We used a descriptive method taking 33 collaborators; in-depth interviews and a 360° evaluation were performed as the technical tools based on the methodology of Martha Alles, a specialist in researching and developing subjects on human resources, organizational behavior and competency management into organizations. By the evaluations results we obtained that such competencies as systematic and strategic vision and empowerment are not fully developed while competences as team management and trainer were well rated and developed. Based on methodology applied it was recommended once the gaps were founds by the analysis, human resource department should work and implement a competency management based on leadership. We conclude leadership is a key competence should have each worker into Josfel Iluminacion SAC Company so we proposed to make some modifications in their recruitment, selection, development and evaluation processes. / Trabajo de Suficiencia Profesional

Video streaming is used daily by people around the world, plays a big role in many Internet users daily lives, and are today responsible for the majority of the Internet traffic. As 360 video streaming services become increasingly popular and each such user session requires much higher bandwidths than traditional video streaming, optimized solutions for this type of video is becoming increasingly important. One method that has been proposed to reduce the bandwidth usage is the usage of proxy servers. In this thesis, we evaluate custom-adapted prefetching policies that tries to improve the users Quality of Experience (QoE). Defining a prefetching policy for something adaptive as 360 video brings challenges that need to be simulated before release in the real world. Without proper testing the prefetch policy can do more harm than good by flooding the network with unnecessary amount of transmissions. Prior research has shown that the QoE of HTTP-based adaptive streaming (HAS) clients can be improved with content-aware prefetching (e.g., Krishnamoothi et al. 2013). However, there have been limited prior work adapting and evaluating such policies in the context of 360 streaming. This thesis presents a simulation-based evaluation of proxy-assisted 360solutions that includes custom designed prefetching polices. The main contributions of the thesis are as follows:First, we implement four types of proxy-assisted prefetching policies and simulate these under two scenarios with different networks conditions. One scenario simulate a network environment with a bottleneck located between the client and proxy while the other scenario simulates a network environment with the bottleneck located between the proxy and server. The cooperation between the client and proxy is evaluated for each scenario and prefetching policy. Second, we evaluate the proxy-assisted prefetching policies in comparison with baselines and each other, in regards of their ability to improve the viewers QoE. Our results show that the bottleneck location has major impact on proxy-performance and that simple prefetching policies can enable clients to download bigger loads of data, which have a significant effect on viewers QoE. Considering that 360 videos require much higher bandwidth then traditional video streaming, service providers may consider integrating prefetching policies for 360 video streaming.
