Technology is changing the structure and dynamics of how humans communicate. Channels of communication are also used for attempts at persuasion, but until now persuasion that (if accepted) would promote the adoption of misinformation could not spread as readily through historical information channels. With the advent of the Internet and World Wide Web this has changed dramatically. In this dissertation it is argued that modern digital communication media such as YouTube, in confluence with what theories of persuasion have to say about how humans deal with persuasion, may create a situation in which misinformation may spread and be accepted on a large scale. The research in this dissertation explores this notion by presenting a group of 120 adolescents who are familiar with the Web with such a misinforming persuasive message. The purpose of which is to determine whether they accept the misinformation presented in the Web-context or are sceptical of it. Different manipulations were done to the persuasive message, known to increase the likelihood of persuasion. The research found that, for this group of participants, no attempt to increase uncritical acceptance of a persuasive message made a statistical difference between different groupings of participants. When intended behaviour was measured in addition to attitude towards the misinformation, participants were even less persuaded. The results are interesting as a starting point for further study, but its generalizability and certain design features must be called into question / Psychology / M.A. (Psychology)

New privacy regulations bring new challenges to organizations that are handling and processing personal data regarding persons within the EU. These challenges come mainly in the form of policies and procedures but also with some opportunities to use technology often used in other sectors to solve problems. In this thesis, we look at the new General Data Protection Regulation (GDPR) in the EU that comes into full effect in May of 2018, we analyze what some of the requirements of the regulation means for the industry of processing personal data, and we look at the possible solution of using hardware security modules (HSMs) to reach compliance with the regulation. We also conduct an empirical study using the Delphi method to ask security professionals what they think the most important aspects of securing personal data, and put that data in relation to the identified compliance requirements of the GDPR to see what organizations should focus on in their quest for compliance with the new regulation. We found that a successful implementation of HSMs based on industry standards and best practices address four of the 35 identified GDPR compliance requirements, mainly the aspects concerning compliance with anonymization through encryption, and access control. We also deduced that the most important aspect of securing personal data according to the experts of the Delphi study is access control followed by data inventory and classification.

本論文主要探討消費者的心情對於其產品屬性偏好與產品態度的影響；產品屬性的部分，強調的是消費者面對商品相關訊息時，對於外部與內部屬性之重視程度，態度的部分，則是指消費者對於商品的喜愛程度與購買意願。本論文以一系列三個實驗，循序漸進探討心情對於消費者屬性重視程度及態度的影響，並試圖整合過去文獻中所謂心情的直接影響與間接影響，將心情對於態度多元的影響路徑統整為一心情影響態度之模型。 研究一首先探討消費者的心情，是否會影響其在面對商品時，對於不同產品屬性重視的程度。研究一結果顯示，好心情的消費者較重視產品的外部屬性，例如：品牌、口碑等，而壞心情的消費者，則較重視產品的內部屬性，例如：體積、功能等。 研究二則從研究一的結果出發，更進一步探討，上述消費者對於產品屬性類型的偏好，是否會影響其對於商品的態度和購買意願。研究二的結果顯示，廣告訴求與消費者所重視的產品屬性搭配與否，的確會顯著的影響消費者的態度。例如：好心情的消費者，若是看到以外部屬性為訴求的廣告，會對該商品有較佳的態度和較高的購買意願；反之，同樣是好心情的消費者，若其所接觸的廣告是以內部屬性訴求為主，則對於該商品的購買意願和態度都不會太高。 研究二的結果驗證心情的好壞會影響消費者對於資訊型態的偏好，就商品而言，就是對於產品屬性類型的偏好，此偏好與廣告訴求一旦結合，便能對於商品態度和購買意願產生影響，此可謂心情的間接影響。心情對於態度的影響，除了間接影響之外，事實上生活經驗與許多文獻也指出，心情的好壞，可能直接影響態度；亦即心情好則態度便佳，心情壞，則對產品的態度也就不好。由此可見心情對於態度之效果，相當多元，研究三便是提出一架構來整合心情的直接與間接影響，亦即，研究三主要目的便是探討何種情境下，心情會產生直接影響，而何種情境之下，會產生間接影響。 研究三指出不同的心情意識，可能是心情循不同路徑對態度產生影響的關鍵。研究三的結果顯示，當心情意識是屬於動機式時，人們對於自己心情的來源有所意識和歸因時，心情對於商品態度的影響，是透過認知歷程，也就是屬性重視程度的偏好與廣告訴求之搭配，來達到效果，亦即所謂的間接影響。而心情意識屬於背景式時，心情只是一種背景氛圍式的存在，人們對於自身心情沒有特別的意識與歸因，心情的歡欣與不悅便會直接反應至態度的好壞，也就是所謂的直接影響。 / The purpose of this research is to understand the effect of moods on consumers’ attitudes, purchase intention, and cognition of product attributes. This research included three studies, and all the hypotheses in the three studies were examined by experiments. In the experiments, respondents’ moods were elicited by short films or music, and the cognition of product attributes and attitudes toward the product were measured. In study one, the relationship between consumers’ moods and their weights on product attributes were probed. The result of study one show that consumers in good mood incline to focus on the extrinsic attributes more than intrinsic attributes; the consumers in bad mood incline to pay more attention to the intrinsic attributes than extrinsic ones. For the neutral mood respondents, there is no difference between the intrinsic and extrinsic attributes in their decision weight. Therefore, this study show that moods indeed influence the cognition of product attributes. Following study one, study two discussed the effect of consumers’ cognition that biased by moods on their attitudes toward products. The results show that when consumers in some moods and have certain tendencies to emphasize intrinsic or extrinsic product attributes, the advertisement that fits to their concerns can induce better attitude than that doesn’t fit. For example, consumers in good mood favor products appealing extrinsic attributes, such as brand and word-of-mouth. On the other hand, if happy consumers see the intrinsic attributes appealing advertisement, such as function and volume, they won’t appreciate those advertisement and products. Study one and two discussed the process that mood influence attitude through cognition. However, according to the literature and life experience, there is another process that mood influences attitude directly and isn’t involved any cognition element. Study three tried to establish a framework to delineate these two processes. The results of study three indicated that mood awareness is the critical factor that influences whether mood influence mood directly or via cognition components. When the consumers are under motivational mood and can aware the sources of moods, the mood effect is indirect and involved cognition elements such as study one and study two. On the other hand, when consumers are under backdrop mood and doesn’t aware the source of mood, the mood can reflect to the attitude directly.

Atualmente, nota-se um crescimento na fabricação de produtos utilizando moldes e matrizes contendo formas geométricas complexas. No entanto, a fabricação destes ferramentais onde se emprega, principalmente, operações de fresamento, não tem acompanhado esta evolução com a mesma velocidade. O advento dos sistemas CAD/CAM, máquinas CNC e da tecnologia de usinagem em altas velocidades (HSC) influenciaram positivamente a fabricação de superfícies complexas. Contudo, nota-se ainda ineficiências neste processo produtivo. A qualidade superficial após as operações de usinagem ainda não é suficiente para que estes ferramentais entrem diretamente na linha de produção. Assim, operações manuais de acabamento são exigidas, elevando o tempo e custo de produção, comprometendo a qualidade dimensional. Com a finalidade de aprimorar a fabricação de moldes e matrizes, este trabalho apresenta uma revisão bibliográfica sobre a usinagem HSC; um estudo sobre a força de usinagem para o fresamento de formas complexas e uma análise sobre a metodologia utilizada por sistemas CAD/CAM e CNC para gerar e interpretar programas NC que contenham movimentações complexas de ferramenta. Análises práticas foram realizadas em um centro de usinagem HSC, e os resultados indicam que as limitações tecnológicas atuais na cadeia CAD/CAM/CNC limitam a usinagem de formas complexas com altas velocidades, reduzindo a velocidade de avanço programada e que as características intrínsecas deste processo de remoção de material demonstrou ser bastante complexo, acarretando em constantes alterações na força de usinagem / In recent years the number of products containing free-form shapes produced by dies and molds have been growing noticeably. However, the milling process used to manufacture those dies and molds does not meet their requirements. The arrival of the CAD/CAM systems and the High Speed Cutting Technology (HSC) helps to improve this manufacturing process. Although to obtain the surface quality needed to meet the dies and molds requirements, a hand finishing still requires. It involves time, money and decrease the product quality. Technological limitations in the CAD/CAM/CNC chain limit the feed rate when milling free-form shape. It also has a negative effect on the surface roughness. Besides, this kind of milling still lacks scientific knowledge of the cutting process. With the aim to support the dies and moulds fabrication, this work presents an overview about HSC Technology; the cutting forces in a non-planar milling; the cutting tool deflection; a detailed description of the process chain involving the CAD/CAM/CNC systems and the methodologies used by those systems to generate and accomplish free-free tool-paths. Free-form milling experiments applying the HSC Technology were made to study the behavior of this process, and the outcomes are presented

Especially business companies try to reduce the rising expenses from storage infrastructure as well as from re-implementation of user interfaces to adapt to evolving tasks. (...)

High Performance Liquid Chromatography (HPLC) is a widely used tech-nique both for detecting and purifying substances in academy and in the industry. In order to facilitate the use of, and knowledge in HPLC, character-ization of stationary phases is of utmost importance. Tailor made characteri-zation methods and workflows are steadily increasing the speed and accura-cy in which new separation systems and methods are developed. In the field fundamental separation science and of preparative chromatography there is always the need for faster and more accurate methods of adsorption isotherm determination. Some of that demand are met with the steadily increase of computational power, but the practical aspects on models and methods must also be further developed. These nonlinear characterization methods will not only give models capable of describing the adsorption isotherm but also actual values of local adsorption energies and monolayer saturation capacity of an individual interaction sites etc.The studies presented in this thesis use modern alkali stable stationary phas-es as a model phase, which will give an insight in hybrid materials and their separation mechanism. This thesis will include an update and expansion in using the Elution by Characteristic Points (ECP) method for determination of adsorption isotherms. The precision is even further increased due to the ability to use slope data as well as an increase in usability by assigning a set of guidance rules to be applied when determine adsorption isotherms having inflection points. This thesis will further provide the reader with information about stationary phase characterization and the power of using existing tech-niques; combine them with each other, and also what the expansion of meth-ods can revile in terms of precision and increased usability. A more holistic view of what benefits that comes with combining a non-linear characteriza-tion of a stationary phase with more common linear characterization meth-ods are presented.
