The purpose of this study was to explore the relationship of the Clinical Nurse Leader (CNL) (AACN) role with the variables of work related stress, quality of life, job satisfaction and anticipated turnover of acute care nurses. Participants included registered nurses (RNs) (N= 94) in Florida recruited from 3 (not for profit) Magnet hospitals in the Tampa Bay Florida area. An ex post facto design was used to test the hypotheses of this study; independent t-tests compared RN’s responses on survey tools measuring work-related stress, quality of life, job satisfaction, and anticipated turnover. Multiple regression analysis was used to examine the interrelationships among these variables. RNs (N=94) completed five survey instruments, including a researcher-developed demographic form. The results of the study showed Aim1 which explored work- related stress did not show any statistical difference between the two groups. Aim 2 which explored job satisfaction and quality of life did not show a difference in the two groups when total scores were analyzed. However, the mental health subscale of the Sf-36(quality of life) was significant ( p=.021), and the general health subscale of the Sf-36 trended toward the CNL group reporting better general health (p=.080). This study revealed that Aim 3 which explored anticipated turnover was statistically significant (p=.047). Standard multiple regression showed a significant relationship existed between CNLs, work related stress and anticipated turnover. The significance of implementation of the CNL role in decreasing turnover through a relationship with these variables may have an important impact on the nursing profession. Specifically, economic implications in reducing turnover that bear further exploration and improving the nursing work environment. This research is the first study to explore the CNL role in relation to these variables.

[pt] Os preços de ativos são fortemente influenciados pelas expectativas. Dessa forma, na presença de dívida colateralizada, a disponibilidade de crédito vai depender dessas expectativas. Nós desenvolvemos um modelo RBC simples, com restrição ao crédito, para formalizar essa intuição. Em seguida, nos construímos um modelo mais complexo, próprio para análise quantitativa, e estudados a relevância desse mecanismo. Nossa principal descoberta é que a restrição ao crédito não afeta a economia significativamente se permitirmos que as firmas substituam entre dívida e equity. Esse resultado se mantém mesmo que essa substituição esteja sujeita a fricções severas. / [en] Asset prices are strongly influenced by expectations. Therefore, in the presence of collateralized debt, credit availability will depend on those expectations. We develop a simple RBC model, with credit constraints, to formalize this intuition. We then build a more complex model, fit for quantitative analysis, in order to study the relevance of the mechanism. Our main finding is that the credit constraint does not significantly affect the economy if we allow firms to substitute between equity and debt. This result holds even if such substitution is subjected to severe frictions.

Abstract User experience research has focused mainly on understanding user experiences during or directly after use. However, studies that focus on anticipated user experiences are scarce. Different methods and metrics have also been developed to measure user experience, but only a few are suitable for evaluating visual user interface design in an anticipated use situation. Moreover, these methods do not provide guidance on how to create suitable examples for research. This thesis investigates how anticipated user experiences, needs, and wishes for visual user interface design can be studied in the early development phase. Furthermore, it investigates how visual design examples can be created and used in these studies as well as their benefits. To answer these questions, it was necessary to create and evaluate prototypes and visual design examples in the user early development phase user experience studies. The examples allowed the study of how interactive elements of user interfaces should be visually designed to draw users’ attention to them. In addition, the thesis explains the means of increasing the visibility of an interactive object and the impact of its use context on its visual design. A constructive design research approach is used in this thesis. The research material is compiled from the artifacts and results of the seven user studies. The main data collection and analysis methods are qualitative, supported with some quantitative methods. The main contribution of this thesis is a practical EDE method for creating visual design examples and evaluating them in early development phase anticipated user experience studies focused on the visual design of a user interface. The second contribution of this thesis is user experience-based preliminary suggestions for the design of interactive elements within the studied user interfaces. The findings are useful for both practitioners and researchers dealing with user experience and visual user interface design. / Tiivistelmä Käyttäjäkokemustutkimus on keskittynyt käyttäjien kokemuksiin varsinaisen käytön aikana tai heti sen jälkeen. Kiinnostus ennakoidun käyttäjäkokemuksen tutkimukseen ennen käyttötilannetta on herännyt vasta hiljattain. Käyttäjäkokemuksen arviointi- ja mittausmenetelmiä on kehitetty paljon, mutta vain harvat niistä sopivat visuaalisen käyttöliittymäsuunnittelun tutkimiseen ennakoidussa käyttötilanteessa. Menetelmät eivät myöskään opasta arviointiin sopivien visuaalisten esimerkkien suunnittelussa. Tutkielmassa selvitetään, miten käyttäjien ennakoituja kokemuksia, tarpeita ja toiveita visuaalisesta käyttöliittymäsuunnittelusta voidaan tutkia tuotekehityksen alkuvaiheessa. Lisäksi selvitetään, kuinka visuaalisia esimerkkejä voidaan luoda ja käyttää alkuvaiheen ennakoidun käyttäjäkokemuksen arvioinneissa sekä pohditaan niiden etuja tutkimuksille. Jotta näihin kysymyksiin voidaan vastata, täytyi luoda prototyyppejä ja visuaalisia esimerkkejä sekä arvioida niitä käyttäjätutkimuksissa. Esimerkkien avulla tutkitaan, miten vuorovaikutteisia käyttöliittymäelementtejä tulisi visuaalisesti esittää, jotta käyttäjä erottaisi ne muusta sisällöstä. Lisäksi selvitetään, miten elementin vuorovaikutteista ilmettä voitaisiin vahvistaa sekä arvioidaan sovellusympäristön vaikutusta elementin visuaaliseen esittämiseen. Tutkimuksen lähestymistapa on konstruktiivinen suunnittelun tutkimus. Aineisto muodostuu artefakteista ja seitsemän käyttäjäkokemustutkimuksen tuloksista. Tutkimusten tiedonkeruumenetelmät ja aineiston analyysimenetelmät ovat laadullisia. Lisämenetelminä on käytetty myös määrällisiä mittareita ja analyysimenetelmiä. Tutkielman päätulos on käytännöllinen EDE-menetelmä, joka on tarkoitettu visuaalisten esimerkkien luontiin ja arviointiin alkuvaiheen ennakoiduissa käyttäjäkokemustutkimuksissa, jotka keskittyvät tuotteen visuaaliseen suunnitteluun. Tutkielman toinen tulos on käyttäjäkokemuspohjaiset alustavat suositukset tutkittujen käyttöliittymien vuorovaikutteisten elementtien visuaaliseen suunnitteluun. Tulokset palvelevat visuaalisen käyttöliittymäsuunnittelun tai käyttäjäkokemuksen parissa työskenteleviä tutkijoita ja teollisuuden ammatinharjoittajia.

With the increasing environmental problems, sustainable consumption is an important consumer behavior. Therefore, it is important to investigate further the significant drivers to and barriers against sustainable consumption, in order to increase the share of sustainable consumption and understanding of consumer behavior. This dissertation identifies two gaps. The first is in understanding consumer positive and negative anticipated emotions as an important factor influencing high-involvement sustainable consumption. The second gap relates to the lack of understanding about the associations between anticipated emotions and personal moral norms in high-involvement sustainable consumption. Against this background, the aim is to contribute to the sustainable consumption literature by investigating the roles and relations of anticipated emotions, personal moral norms, and weighing costs and benefits as drivers to and barriers against consumer adoption of a high-involvement sustainable product. A literature review and two empirical studies were conducted. Consumer adoption of alternative fuel vehicles is the specific sustainable consumption. Using quantitative methods, this phenomenon is investigated in the empirical studies conducted in Sweden. It was shown that anticipated emotions have direct effects on consumers' intention to adopt alternative fuel vehicles. Moreover, positive anticipated emotions (e.g. pride, pleasure, happiness) are drivers of sustainable consumption, while negative anticipated emotions (e.g. regret, embarrassment) are barriers against the sustainable consumption. This dissertation suggests an extension to the norm activation model, and shows that moral norms, ascription of responsibility, and awareness of environmental problems influence consumers' intentions through consumers’ anticipated emotions. For people who perceive high social norms related to decreasing the environmental impacts of car driving, the influence of positive anticipated emotions and personal moral norms are stronger. This points toward the social aspect of sustainable consumption and suggests that targeting the consumers who perceive high social norms is an important step to promoting sustainable consumption. Findings would be of relevance to marketers, policymakers and environmental organizations. Creating awareness and communicating personal responsibilities and moral norms related to the environment and consumption are important drivers for consumer adoption of sustainable products. However, it is noteworthy that consumer anticipated emotions about high-involvement sustainable products (such as alternative fuel vehicle) have also important influence on the sustainable consumption. Thus, consumer anticipated emotions should be considered in designing promotion programs.

Orientador: Dirceu Maximino Fernandes / Banca: Silvio José Bicudo / Banca: Carlos Sérgio Tiritan / Resumo: O rendimento de grãos de milho é influenciado pela disponibilidade de nitrogênio no solo durante o ciclo de desenvolvimento da planta. O objetivo deste trabalho foi avaliar em sistema de semeadura direta, os resultados obtidos com a adubação nitrogenada em pré-semeadura e em cobertura na cultura do milho analisando a produtividade de grãos desta cultura e da cultura subsequente, o girassol. O experimento foi conduzido em uma área no sistema de semeadura direta há cinco anos, no Sítio Santo Antônio em Pirassununga, SP no ano agrícola 2004/2005. Utilizou-se o delineamento experimental de parcelas subdivididas, sendo 3 híbridos de milho, 4 épocas de adubação e 5 repetições. A dose em cobertura de 102,5 kg ha-1 N, com o adubo 25-15-10, tendo como fonte de N o nitrato de amônio, foi aplicado nas seguintes épocas: Tratamento 1 (E1): testemunha (sem aplicação antecipada e sem cobertura de N); Tratamento 2 (E2): todo N em cobertura com milho de 3 a 4 folhas expandidas; Tratamento 3 (E3): em cobertura metade da dose de N com milho de 3 a 4 folhas expandidas e o restante de N com milho de 7 a 8 folhas expandidas; e Tratamento 4 (E4): metade da dose de N em pré-semeadura (15 dias antes da semeadura), e a metade restante de N em cobertura com milho de 3 a 4 folhas expandidas. Após a colheita do milho semeou-se girassol nestas áreas. Como resultado para o milho tem-se os híbridos se comportaram de maneira diferentes quanto as épocas de adubação de cobertura de N, onde os híbridos AG 8060 e Pointer não apresentam diferenças significativas entre a E2, E3 e E4; já o híbrido DKB 390 apresenta sua melhor resposta na E2 e a menor média na E4. Para a cultura do girassol, as épocas de adubação de milho não interferem na produtividade, porém, o girassol semeado após o híbrido DKB 390 apresenta menor produtividade quando comparado com os híbridos AG 8060 e Pointer. / Abstract: The income of grains of corn is influenced by the avaiability of nitrogen in soil during the cycle of a plant development. The mainly objective of this research evaluate the results obtained with the nitrogen fertilization in pre-sowing and in covering of the culture of corn in a no-tillage system analyzing the productivity of grains from this culture and the subsequent culture, the sunflower. The experimented was in an area were there had already been developed the no-tillage system for five years, in the Santo Antônio Farm in Pirassununga, SP, in agricultural year 2004/2005. Used the experimental outline of subdivided parcels, being 3 corns hybrids, 4 timings of fertilization and 5 repetitions. The dose covering 102,5 kg ha-1 N, with 25-15-10 fertilizer, and as a source of N ammonium nitrate was applied at the following times: Treatment 1 (E1): testimony ( without anticipated application of without application of N in covering); Treatment 2 (E2): all N in covering with corn of 3 to 4 expanded leaves; Treatment 3 (E3): in covering with half dose of N with corn of 3 to 4 expanded leaves and half of the left dose of N with corn of 7 to 8 expanded leaves; and Treatment 4 (E4): half dose of N in pre-sowing (15 days before sowing), and half dose of N in covering with corn of 3 to 4 expanded leaves. After of harvest of corn was sowing sunflower this area. As result for the corn has been the hybrids behaved as different seasons as the times of covering fertilization of N, where the hybrid AG 8060 and Pointer not differ significantly between the E2, E3 and E4; since the hybrid DKB 390 presents its best response in the E2 and the lowest average in the E4. For the culture of sunflower, the times of fertilization of corn does not interfere with productivity, however, the sunflower sown after the hybrid DKB 390 has lower productivity compared to the hybrid AG 8060 and Pointer. / Mestre

Adaptability is an intrinsic property of software systems that require adaptation to cope with dynamically changing environments. Achieving adaptability is challenging. Variability is a key solution as it enables a software system to change its behavior which corresponds to a specific need. The abstraction of variability is to manage variants, which are dynamic parts to be composed to the base system. Run-time variability realizes these variant compositions dynamically at run time to enable adaptation. Adaptation, relying on variants specified at build time, is called anticipated adaptation, which allows the system behavior to change with respect to a set of predefined execution environments. This implies the inability to solve practical problems in which the execution environment is not completely fixed and often unknown until run time. Enabling unanticipated adaptation, which allows variants to be dynamically added at run time, alleviates this inability, but it holds several implications yielding system instability such as inconsistency and run-time failures. Adaptation should be performed only when a system reaches a consistent state to avoid inconsistency. Inconsistency is an effect of adaptation happening when the system changes the state and behavior while a series of methods is still invoking. A software bug is another source of system instability. It often appears in a variant composition and is brought to the system during adaptation. The problem is even more critical for unanticipated adaptation as the system has no prior knowledge of the new variants. This dissertation aims to achieve anticipated and unanticipated adaptation. In achieving adaptation, the issues of inconsistency and software failures, which may happen as a consequence of run-time adaptation, are evidently addressed as well. Roles encapsulate dynamic behavior used to adapt players representing the base system, which is the rationale to select roles as the software system's variants. Based on the role concept, this dissertation presents three mechanisms to comprehensively address adaptation. First, a dynamic instance binding mechanism is proposed to loosely bind players and roles. Dynamic binding of roles enables anticipated and unanticipated adaptation. Second, an object-level tranquility mechanism is proposed to avoid inconsistency by allowing a player object to adapt only when its consistent state is reached. Last, a rollback recovery mechanism is proposed as a proactive mechanism to embrace and handle failures resulting from a defective composition of variants. A checkpoint of a system configuration is created before adaptation. If a specialized bug sensor detects a failure, the system rolls back to the most recent checkpoint. These mechanisms are integrated into a role-based runtime, called LyRT. LyRT was validated with three case studies to demonstrate the practical feasibility. This validation showed that LyRT is more advanced than the existing variability approaches with respect to adaptation due to its consistency control and failure handling. Besides, several benchmarks were set up to quantify the overhead of LyRT concerning the execution time of adaptation. The results revealed that the overhead introduced to achieve anticipated and unanticipated adaptation to be small enough for practical use in adaptive software systems. Thus, LyRT is suitable for adaptive software systems that frequently require the adaptation of large sets of objects.

Digital assistants such as Google Assistant and Alexa are becoming more and more common in people's homes through smart speakers. Technologies that assist with stress management have increased as well, leading to an abundance of stress management applications for different devices. However, there is a limited amount of research regarding how advanced digital assistants could support stress management and be integrated into users' daily activities. Therefore, our study explores how people anticipate that they would relate to an advanced digital assistant in the future and how they would integrate it into their everyday activities for stress management. Our study shows that important aspects of digital assistants relate to their objectivity, personalization, and adaptability in terms of type of interaction in different contexts. The study also finds that privacy and control, such as a mute function or an on & off function, are desired in order to adjust the digital assistant and integrate it into everyday activities. Finally, stress management with digital assistants is highly personal and how users would relate to and integrate digital assistants into their everyday activities for stress management is unique to each user.

Telehealth and telemedicine have revolutionized the healthcare system in terms of access to information and remote medical treatment. While there is a great deal of literature on current perceptions of telehealth care systems, relatively little is known about perceived user needs and acceptance of future telehealth systems. One way to assess future attitudes is to evaluate anticipated usage of telehealth devices through perceived advantages and disadvantages. Additionally, this study seeks to assess the reliability of a new measure of technology acceptance that capitalizes on human motivation using self-determination theory. An online survey consisted of an original 40-item measure of motivation to use telehealth technology, the Psychosocial Impact of Assistive Devices Scale (PIADS; Jutai & Day, 1996), questions adapted from Edwards et al. (2014) about perceived advantages and disadvantages of telehealth devices, and open-ended questions about advantages, disadvantages, and concerns of interacting with telehealth devices in the future. The open-ended questions were coded for themes. Results also indicated that there was a high reliability between the MUTT and the PIADS, however the MUTT was slightly more reliable. Significant correlations were found between the overall MUTT and subscales of autonomy, competence, relatedness, and goals, as well as moderate correlations between the subscales of the PIADS (i.e., competence, adaptability, self-esteem) and the MUTT. The results of this research will be discussed further.
