This thesis explores young tourists' perceptions of fear while they are on holiday. This work is important because it sheds light on tourists' emotional experiences on holiday, adding to our overall understanding of tourist behaviour. While the importance of investigating perceptions of fear has been recognized within a number of different disciplines (e.g. psychology, sociology, criminology, marketing), perceptions of fear have remained relatively unexplored within the tourism experience. This thesis also investigates young tourists' perceptions of fear from a gender perspective. Although gender has been regarded as one of the most important factors influencing perceptions of fear, gendered perceptions of fear among tourists in the holiday environment in general, and young tourists in particular, have received little attention. The thesis is based on three months of fieldwork conducted in the summer of 2007 on the island of Ios, Greece. The choice of Ios as a study site was based on the fact that the island is promoted as the 'party island of Greece' and attracts many young tourists. Twenty-five in-depth interviews were conducted among young tourists on the island. In order to explore gender-based similarities and differences in the perception and expression of fear, the interviews were conducted with 13 females and 12 males. Systematic observations were also carried out during the fieldwork. The findings reveal that, although some respondents perceived fear as a negative emotion, others referred to fear as a positive component in the tourism experience. In particular, it was found that while on holiday on Ios young tourists participated in activities that they perceived as risky in order to experience fear. However, only optimal levels of fear were conceived as pleasant. With regard to gendered perceptions of fear, the results show that gender, despite having been traditionally constructed as a binary concept, did not play a major role in influencing young tourists' perceptions of fear on holiday. Rather, with the exception of women's concerns of sexual violence, the findings of this thesis demonstrate that more marked differences occurred in the perception and expression of fear among the various masculinities and femininities than between men and women.

This thesis seeks to explore how management can work together to adopt an Inter-organisational Information System (IOIS) for Supply Chain Management (SCM) at different levels of collaboration sophistication. 20 common issues associated with collaboration and adoption of IOIS for SCM, were identified from the current literature. Two theoretical frameworks were developed. First, an IOIS for SCM Adoption Framework was constructed to understand the IOIS for SCM adoption process. Secondly, an Inter-organisational Collaboration Framework was constructed and used as a lens to examine and understand the process of inter-organisational collaboration. Five underlying theories, namely agency, needs and motivation, resource dependency, cultural and negotiated order, were drawn on to develop an understanding of collaboration in this latter framework. The study of collaboration for IOIS adoption is exploratory. Eight organisations were approached from three industries and sixteen interviews were carried out with managers who are involved in the supply chain activities. Data was primarily collected using an interview instrument based on literature, and documentary and archival evidence. Interviews were transcribed and cross-case analysis was conducted on the data. Three of the four levels of collaboration sophistication were supported. At the highest level of collaboration, namely cooperation sophistication, the organisations that were studied have growth motivations, same interests and common business objectives, and prepare to develop strategy and finance projects while reengineering their business processes and redesigning their supply chains collectively. Collaboration is not limited to one dimension but multi-dimensional. An organisation collaborates with its partners in one project but that at the same time, they may not want to collaborate on a different project due to differences in business objectives. When there is a disagreement between parties, negotiation is an important process to help resolve their differences. The process of collaboration was summarised into three perspectives: industry, intra-organisational and inter-organisational. These perspectives can assist practitioners who need to understand how to address the process of collaboration in the adoption of IOISs for SCM with their partners.

abstract: The American Heart Association recommended in 1997 the data elements that should be collected from resuscitations in hospitals. (15) Currently, data documentation from resuscitation events in hospitals, termed ‘code blue’ events, utilizes a paper form, which is institution-specific. Problems with data capture and transcription exists, due to the challenges of dynamic documentation of patient, event and outcome variables as the code blue event unfolds. This thesis is based on the hypothesis that an electronic version of code blue real-time data capture would lead to improved resuscitation data transcription, and enable clinicians to address deficiencies in quality of care. The primary goal of this thesis is to create an iOS based application, primarily designed for iPads, for code blue events at the Mayo Clinic Hospital. The secondary goal is to build an open-source software development framework for converting paper-based hospital protocols into digital format. The tool created in this study enabled data documentation to be completed electronically rather than on paper for resuscitation outcomes. The tool was evaluated for usability with twenty nurses, the end-users, at Mayo Clinic in Phoenix, Arizona. The results showed the preference of users for the iPad application. Furthermore, a qualitative survey showed the clinicians perceived the electronic version to be more accurate and efficient than paper-based documentation, both of which are essential for an emergency code blue resuscitation procedure. / Dissertation/Thesis / Masters Thesis Computer Science 2015

abstract: Computational thinking, the fundamental way of thinking in computer science, including information sourcing and problem solving behind programming, is considered vital to children who live in a digital era. Most of current educational games designed to teach children about coding either rely on external curricular materials or are too complicated to work well with young children. In this thesis project, Guardy, an iOS tower defense game, was developed to help children over 8 years old learn about and practice using basic concepts in programming. The game is built with the SpriteKit, a graphics rendering and animation infrastructure in Apple’s integrated development environment Xcode. It simplifies switching among different game scenes and animating game sprites in the development. In a typical game, a sequence of operations is arranged by players to destroy incoming enemy minions. Basic coding concepts like looping, sequencing, conditionals, and classification are integrated in different levels. In later levels, players are required to type in commands and put them in an order to keep playing the game. To reduce the difficulty of the usability testing, a method combining questionnaires and observation was conducted with two groups of college students who either have no programming experience or are familiar with coding. The results show that Guardy has the potential to help children learn programming and practice computational thinking. / Dissertation/Thesis / Masters Thesis Computer Science 2017

As consequências múltiplas desta patologia que levam a dispneia, limitação da capacidade de exercício, exacerbações, baixa qualidade de vida relacionada à saúde e alta taxa de morbimortalidade frequentemente não apresentam relação direta com as variáveis da espirometria, técnica de função pulmonar utilizada amplamente no diagnóstico e acompanhamento destes pacientes. Sendo a melhora nos desfechos centrados nos pacientes, em especial sintomas de dispneia e qualidade de vida, um dos alvos principais no tratamento destes indivíduos, a identificação de um método objetivo de avaliação da função pulmonar que melhor reflita estes desfechos é altamente desejável, tanto na clínica diária quanto em pesquisas, para que sua subjetividade seja comparada com parâmetros objetivos de avaliação de gravidade e resposta ao tratamento. O sistema de oscilometria de impulsos (IOS) é uma técnica ainda pouco difundida e estudada de função pulmonar que avalia a resistência e a reatância do sistema respiratório em resposta a várias frequências oscilatórias, permitindo avaliação diferenciada das pequenas e grandes vias aéreas separadamente, com as vantagens de ser de fácil realização e não necessitar de manobras forçadas, despontando como uma técnica de grande potencial na avaliação da função pulmonar destes pacientes. Esta dissertação é composta por uma fundamentação teórica e um artigo original. Na primeira são abordados aspectos inerentes ao tema sobre a DPOC como sua definição, fisiopatologia, diagnóstico, tratamento e monitorização da resposta ao tratamento, destacando a utilidade do IOS neste contexto. Foram selecionados os trabalhos mais relevantes a partir de pesquisa bibliográfica utilizando os seguintes unitermos isolados ou em combinação: doença pulmonar obstrutiva crônica (dpoc) (copd), oscilometria de impulso (impulse oscillometry), função pulmonar (lung function). Os bancos de dados pesquisados foram MEDLINE/Pubmed, Scielo, LILACS. No artigo original 51 pacientes com DPOC estável em tratamento regular foram submetidos a avaliação por meio do IOS, espirometria e feita a correlação das variáveis do IOS com o VEF1 e o FEF25-75% e de todas as variáveis do IOS e do VEF1 com os escores CAT (Copd Assessment Test) que avalia a qualidade de vida relacionada a saúde nos pacientes com DPOC e com a escala do mMRC (escala modificada de avaliação da dispneia do Medical Research Council). Correlações estatisticamente significantes foram encontradas entre os desfechos centrados nos pacientes e as variáveis do IOS, ocorrendo também correlação significativa entre as variáveis do IOS estudadas e o VEF1. Concluímos que os parâmetros do IOS podem ser facilmente obtidos, avaliam a função pulmonar de forma mais detalhada que a espirometria e têm associação com a qualidade de vida relacionada a saúde e dispneia nos pacientes com DPOC. / The clinical picture associated with the chronic obstructive pulmonary disease (COPD), particularly dyspnea, varies a lot between patients as a result of the complex interactions between systemic and pulmonary changes induced by the disease and also due to individual perception of symptoms. The multiple consequences of this pathology that leads to breathlessness, exercise capacity limitation, exacerbations, poor health related quality of life and high mortality rate often have no direct relation to the variables measured by spirometry, a lung function technique widely used for the diagnosis and monitoring of these patients. As the improvement in patients focused outcomes, especially symptoms of dyspnea and quality of life, one of the main targets in the treatment of these individuals, the identification of an objective assessment of lung function that best reflects these outcomes is highly desirable, both in daily practice and in research, as their subjectivity could be compared to objective parameters in assessing severity and response to treatment. The impulse oscillometry system (IOS) is a pulmonary function evaluation technique still not widely disseminated that measures the resistance and reactance of the respiratory system in response to various oscillatory frequencies, allowing differentiated assessment of small and large airways separately. It has the advantages that needs little patient’s cooperation and does not require forced maneuvers. IOS is emerging as a technique of great potential in these patients lung function evaluation. This thesis consists of a theoretical grounding and an original article. In the first it is addressed aspects inherent to COPD such as definition, pathophysiology, diagnosis, treatment and monitoring response to treatment, highlighting the utility of IOS in this context. We selected the most relevant papers from the literature and the search adopted the following key words alone or in combination: chronic obstructive pulmonary disease (copd), impulse oscillometry, lung function. Databases searched were MEDLINE / PubMed, SciELO, LILACS. For the original article were studied 51 patients with stable COPD on regular treatment that underwent evaluation by the IOS (R5Hz, R5Hz-R20Hz, Fres and X5Hz) and spirometry (FEV1 and FEF 25%-75%) and correlation between IOS variables with FEV1 and between these two and the Copd Assessment Test scores (CAT) that evaluates the health related quality of life in patients with COPD and the modified scale of dyspnea assessment of the Medical Research Council (mMRC) were done. Statistically significant correlations were found between patient-centered outcomes (CAT and mMRC) and the IOS variables, also significant correlations were found between the studied IOS variables and FEV1. We conclude that the IOS parameters can be easily measured, offer more detail in lung function assessment than spirometry and have good correlation with health related quality of life and dyspnea in patients with COPD.

Smartphones combine telephony services with data services in a single device. In 2007, Apple released a new generation of phones run by iOS operating system, called iPhones. Android phones were developed by Google and were released the following year. Smartphones use has increased a lot and they have become one of the most common devices that are being used in most of companies nowadays. The concept BYOD stands for Bring Your Own Device, means that employees may use their own smartphones at work. This makes using the built-in security features in smartphones particularly important, not only to protect employees’ private information but also to protect their corporate information. Early research has shown that threats and attacks have also increased on smartphones. Hackers have focused their attacks on smartphones more than before. And have created mobile-based viruses, malware and spyware that target vulnerable smartphones. Smartphone users nowadays do not have much control of their smartphones security according to previous researches. However, smartphones manufacturers constantly add new built-in security features with each new version of operating system to protect them from various threats. Smartphone manufacturers may use the acquired final data to improve their products’ security and increase the use of mobile built-in security features. The current study researches students’ interaction and use of the built-in security features available in smartphones run by both Android and iOS operating systems. The study does not divide students into smaller groups; it rather focuses on all students as one group. Although this study was conducted in the University of Skovde in Sweden, its conclusion can be applied to a bigger population regardless of location. Today's students are tomorrow’s employees and managers who will have the responsibility to protect their companies’ proprietary and sensitive information. Therefore, it is critical that they understand and implement all up-to-date procedures to protect their smartphones and their companies. A quantitative study is conducted through a survey in order to reach as many participants as possible. Lime Survey tool is utilized to create surveys and to gather data. Statistics and diagrams are also used to demonstrate results to readers. A total of 201 participants completed the entire study, 134 participants answered the Android survey and 67 answered the iOS survey. The current survey results have shown, through a model that converts participants’ answers into a flow chart, that the use of the built-in security features varies among participating students. The use of these built-in security features was low in general. More than half of all participants do not use certain functions at all. The general low use of the built-in security features can be attributed to many reasons. This survey showed that the main reason of that was the lack of participants’ knowledge of these built-in security features. Several solutions exist for this lack of knowledge of participants, but they do not fall within the scope of this study therefore not discussed herein.
