Dry eye syndrome is a multifactorial disease of the tear film, resulting from the instability of the lacrimal functional unit that produces volume change, up or tear distribution. In patients in intensive care the cause is enhanced due to various risk factors, such as mechanical ventilation, sedation, lagophthalmos, low temperatures, among others. The study's purpose is to build an assessment tool of Dry Eye Severity in patients in intensive care units based on the systematization of nursing care and their classification systems. The aim of this study is to build an assessment tool of Dry Eye Severity in hospitalized patients in Care Unit Intensiva.Trata is a methodological study conducted in three stages, namely: context analysis, concept analysis, construction of operational definitions and magnitudes of nursing outcome. For the first step we used the methodological framework for Hinds, Chaves and Cypress (1992). For the second step we used the model of Walker and Avant and an integrative review Whitemore seconds, Knalf (2005). This step enabled the identification of the concept of attributes, background and consequent ground and the construction of the settings for the result of nursing severity of dry eye. For the construction of settings and operational magnitudes, it was used Psicometria proposed by Pasquali (1999). As a result of context analysis, visualized from the reflection that the matter should be discussed and that nursing needs to pay attention to the problem of eye injury, so minimizing strategies are created this event with a high prevalence. With the integrative review were located from the crosses 19 853 titles, selected 215, and from the abstracts 96 articles were read in full. From reading 10 were excluded culminating in the sample of 86 articles that were used to analyze the concept and construction of settings. Selected articles were found in greater numbers in the Scopus database (55.82%), performed in the United States (39.53%), and published mainly in the last five years (48.82). Regarding the concept of analysis were identified as antecedents: age, lagophthalmos, environmental factors, medication use, systemic diseases, mechanical ventilation and ophthalmic surgery. As attributes: TBUT <10s, Schimer I test <5 mm in Schimer II test <10mm, reduced osmolarity. As consequential: the ocular surface damage, ocular discomfort, visual instability. The settings were built and added indicators such as: decreased blink mechanism and eyestrain.

The scope of this study was to identify socioeconomic contextual and health care factors in primary care associated with maternal near misses and their marker conditions. This is an ecological study that used aggregated data of 63 clusters formed by the municipalities of State of Rio Grande do Norte, Brazil, using the Skater method of area regionalization, as the unit of analysis. The ratio of maternal near misses and their marker conditions were obtained from the Hospital Information System of the Brazilian Unified Health System. In multiple linear regression analysis, there was a significant association between maternal near misses and variables of poverty and poor primary health care. Hypertensive disorders were also associated with poverty and poor primary care and the occurrence of hemorrhaging was associated with infant mortality. It was observed that the occurrence of maternal near misses is linked to unfavorable socioeconomic conditions and poor quality health care that are a reflection of public policies that accentuate health inequalities.

This paper derives a theoretical framework for consideration of both the technologically driven dimensions of mobile payment solutions, and the associated value proposition for customers. Banks promote traditional payment instruments whose value proposition is the management of risk for both consumers and merchants. These instruments are centralised, costly and lack decision support functionality. The ubiquity of the mobile phone has provided a decentralised platform for managing payment processes in a new way, but the value proposition for customers has yet to be elaborated clearly. This inertia has stalled the design of sustainable revenue models for a mobile payments ecosystem. Merchants and consumers in the meantime are being seduced by the convenience of on-line and mobile payment solutions. Adopting the purchase and payment process as the unit of analysis, the current mobile payment landscape is reviewed with respect to the creation and consumption of customer value. From this analysis, a framework is derived juxtaposing customer value, related to what is being paid for, with payment integration, related to how payments are being made. The framework provides a theoretical and practical basis for considering the contribution of mobile technologies to the payment industry. The framework is then used to describe the components of a mobile payments pilot project being run on a trial population of 250 students on a campus in Ireland. In this manner, weaknesses in the value proposition for consumers and merchants were highlighted. Limitations of the framework as a research tool are also discussed.

The study examines the short-run and long-run causality running from real economic growth to real foreign direct investment inflows (RFDI). Other variables such as education (involving combination of primary, secondary and tertiary enrolment as a proxy to education), real development finance, unskilled labour, to real RFDI inflows are included in the study. The time series data covering the period of 1983 -2013 are examined. First, I applied Augmented Dicky-Fuller (ADF) technique to test for unit root in variables. Findings shows all variables integrated of order one [I(1)]. Thereafter, Johansen Co-integration Test (JCT) was conducted to establish the relationship among variables. Both trace and maximum Eigen value at 5% level of significance indicate 3 co-integrated equations. Vector error correction method (VECM) was applied to capture short and long-run causality running from education, economic growth, real development finance, and unskilled labour to real foreign direct investment inflows in the Republic of Rwanda. Findings shows no short-run causality running from education, real development finance, real GDP and unskilled labour to real FDI inflows, however there were existence of long-run causality. This can be interpreted that, in the short-run; education, development finance, finance and economic growth does not influence inflows of foreign direct investment in Rwanda; but it does in long-run. From the policy perspective, the Republic of Rwanda should focus more on long term goal of investing in education to improve human capital, undertake policy reforms that promotes economic growth, in addition to promoting good governance to attract development finance – especially from Nordics countries (particularly Norway and Denmark).

Human societies are reliant on the functioning of the hydrologic cycle. The atmospheric branch of this cycle, often referred to as moisture recycling in the context of land-to-land exchange, refers to water evaporating, traveling through the atmosphere, and falling out as precipitation. Similar to the surface water cycle that uses the watershed as the unit of analysis, it is also possible to consider a ‘watershed of the sky’ for the atmospheric water cycle. Thus, I explore the precipitationshed - defined as the upwind surface of the Earth that provides evaporation that later falls as precipitation in a specific place. The primary contributions of this dissertation are to (a) introduce the precipitationshed concept, (b) provide a quantitative basis for the study of the precipitationshed, and (c) demonstrate its use in the fields of hydrometeorology, land-use change, social-ecological systems, ecosystem services, and environmental governance. In Paper I, the concept of the precipitationshed is introduced and explored for the first time. The quantification of precipitationshed variability is described in Paper II, and the key finding is that the precipitationsheds for multiple regions are persistent in time and space. Moisture recycling is further described as an ecosystem service in Paper III, to integrate the concept into the existing language of environmental sustainability and management. That is, I identify regions where vegetation more strongly regulates the provision of atmospheric water, as well as the regions that more strongly benefit from this regulation. In Paper IV, the precipitationshed is further explored through the lens of urban reliance on moisture recycling. Using a novel method, I quantify the vulnerability of urban areas to social-ecological changes within their precipitationsheds. In Paper V, I argue that successful moisture recycling governance will require flexible, transboundary institutions that are capable of operating within complex social-ecological systems. I conclude that, in the future, the precipitationshed can be a key tool in addressing the complexity of social-ecological systems.

O presente trabalho tem como objetivo definir, analisar e identificar por meio de um estudo de caso, as dimensões de comprometimento organizacional: afetivas, instrumental e normativa dos gestores do campus do Limoeiro do Norte, que estão em fase de estágio probatório e dos gestores do campus Fortaleza que já passaram desse estágio, traçar um comparativo e relacionar ambos os casos. Norteado por um modelo teórico de comprometimento organizacional abordado por Meyer e Allen (1991; 1997). Comprometimento no setor público neste estudo tem-se como unidade de análise duas instituições federais de educação, ciência e tecnologia. Como os gestores são, na maioria das vezes, responsáveis pelo desenvolvimento de uma força de trabalho capaz e comprometida, sua atuação torna-se de fundamental importância no âmbito da educação, aliado a competência técnica e a vontade política de ações planejadas. De acordo com a pesquisa descritiva e quantitativa, foram aplicados questionários já testados e validados, contendo aspectos semi-estruturados, onde foi dividido em duas partes: a primeira, com seis itens, abordando as características pessoais e funcionais dos gestores do IFCE de cada campus estudado, e segunda, que possui dezoito itens divididos nas três dimensões do comprometimento organizacional: afetivo, instrumental e normativo, tudo baseado na escala de mensuração do comprometimento de Meyer e Allen (1997) modelo internacionalmente aceito e validado. Os resultados obtidos na pesquisa apontaram que dos 35 gestores do campus Limoeiro do Norte o comprometimento organizacional que obteve maior média foi o afetivo. Os gestores estáveis do campus Fortaleza, também apontaram a dimensão afetiva com a maior média de comprometimento. Com isso os estudos balizam que não há uma possível relação com o fator tempo na instituição, uma vez que a maioria dos gestores do campus Fortaleza possui mais de uma década de atuação, enquanto os do campus Limoeiro do Norte, possuem menos de três anos na instituição. A maior parte dos pesquisados nos campi defendem uma forte relação na instituição, já se sentem de casa, o vínculo se estabelece pela presença de sentimentos, afeição e identificação, até mesmo pelo fato dos gestores permanecerem mais tempo no trabalho que na sua prápria casa, ele faz da organização um esteio do seu próprio lar. Conclui-se que os resultados não permitem afirmar que as dimensões do comprometimento estão relacionadas ao tempo de atuação dos gestores na instituição. / This paper aims to define, analyze and identify through a case study, the dimensions of organizational commitment: affective, continuance and normative managers campus of Castle Hayne, who are in their probationary period and the managers of Fortaleza campus who have passed this stage, draw a comparison and to relate both cases. Guided by a theoretical model of organizational commitment by Meyer and Allen (1991; 1997) approached. Commitment in the public sector in this study has as unit of analysis two federal institutions of science and technology education. As managers are, in most cases, responsible for developing a workforce capable and committed, its performance becomes very important in education, combined with technical competence and political will of planned actions. According to the descriptive and quantitative research, questionnaires were applied, tested and validated, containing aspects of semi-structured, which was divided into two parts: the first, with six items, addressing the personal and functional characteristics of the managers of each campus IFCE studied, and second, which has eighteen items divided into the three dimensions of organizational commitment: affective, continuance and normative, all based on a scale to measure the commitment of Meyer and Allen (1997) model is internationally accepted and validated. The results obtained in this research showed that the 35 managers of the Castle Hayne campus organizational commitment that was obtained more affective. Managers stable campus Fortaleza, also pointed to the affective dimension with the highest average commitment. With this guiding studies that there is a possible relationship with the time factor in the institution, since most managers campus Fortaleza has over a decade of operation, while the Castle Hayne campus, have less than three years in institution. Most of the campuses surveyed favor a strong relationship with the institution, already feel at home, the link is established by the presence of feelings, affection and identification, even by the fact that managers stay longer at work than at home, he is a mainstay of the organization of your own home. We conclude that the results do not allow us to state that the dimensions of commitment are related to time of performance of managers in the institution.

This research is part of the field of organizational studies, focusing on organizational purchase behavior and, specifically, trust interorganizational at the purchases. This topic is current and relevant by addressing the development of good relations between buyer-supplier that increases the exchange of information, increases the length of relationship, reduces the hierarchical controls and improves performance. Furthermore, although there is a vast literature on trust, the scientific work that deal specifically at the trust interorganizational still need further research to synthesize and validate the variables that generate this phenomenon. In this sense, this investigation is to explain the antecedents of trust interorganizational by the relationship between the variable operational performance, organizational characteristics, shared values and interpersonal relationships on purchases by manufacturing industries, in order to develop a robust literature, most consensual, that includes the current sociological and economic, considering the effect of interpersonal relationships in this phenomenon. This proposal is configured in a new vision of the antecedents of interorganizational trust, described as significant quantitative from models Morgan and Hunt (1994), Doney and Cannon (1997), Zhao and Cavusgil (2006) and Nyaga, Whipple, Lynch (2011), as well as qualitative analysis of Tacconi et al. (2011). With regard to methodological aspects, the study assumes the form of a descriptive, survey type, and causal trace theoretical and empirical. As for his nature, the investigation, explicative character, has developed a quantitative approach with the use of exploratory factor analysis and structural equation modeling SEM, with the use of IBM software SPSS Amos 18.0, using the method of maximum verisimilitude, and supported by technical bootstraping. The unit of analysis was the buyer-supplier relationship, in which the object under investigation was the supplier organization in view of the purchasing company. 237 valid questionnaires were collected among key informants, using a simple random sampling developed in manufacturing industries (SIC 10-33), located in the city of Natal and in the region of Natal. The first results of descriptive analysis demonstrate the phenomenon of interorganizational trust, in which purchasing firms believe, feel secure about the supplier. This demonstration showed high levels of intensity, predominantly among the vendors that supply the company with materials that are used directly in the production process. The exploratory and confirmatory factor analysis, performed on each variable alone, generated a set of observable and unobservable variables more consistent, giving rise to a model, that needed to be further specified. This again specify model consists of trajectories was positive, with a good fit, with a composite reliability and variance extracted satisfactory, and demonstrates convergent and discriminant validity, in which the factor loadings are significant and strong explanatory power. Given the findings that reinforce the model again specify data, suggesting a high probability that this model may be more suited for the study population, the results support the explanation that interorganizational trust depends on purchases directly from interpersonal relationships, sharing value and operating performance and indirectly of personal relationships, social networks, organizational characteristics, physical and relational aspect of performance. It is concluded that this trust can be explained by a set of interactions between these three determinants, where the focus is on interpersonal relationships, with the largest path coefficient for the factor under study

The present inquiry has as main objective to understand the process of formation of the international strategies of the exporting companies of fruits of the RN through the theory of the resource dependence. Aiming at to clarify as the companies they can carry through the process of internationalization through this theory had been study the behavior and economic theories of the process of internationalization of companies. Amongst the economic theories they are distinguished the eclectic paradigm of Dunning (1958), Vernon (1669) through the theory of the cycle of the product and Bucley and Casson (1979) with the theory of the international operations. In the mannering boarding they had been investigated the school of Upsala through Johanson and Valnhe (1977) with the concept of the increasing of the markets and in the distance psychic starts and the interaction of the purchaser-salesman of Hallen and Wiedersheim-Paul (1979). In this perspective it observes main the occured changes in the organization in function of this process, following the rules observed by the gradual ingression in the international market, having as base ways of entrances in the external market used by these companies, in view of the frist phase that the company presents of businesses. Ahead of you analyze of these theories the study searches to analyze the convergence of the concepts proclaimed for the theory of the dependence of resources (PFEFFER; SALANCIK, 1978). and strategies of internationalization of the companies. The research is characterized as qualitative case study which adopts and exploratory and analytical type, retrospective matrix. The adopted strategy is of case study and the unit of analysis consisting of the Finobrasa, pertaining company to the Vicunha Group. The main method of collection of data was halfstructuralized interview allied the documentary research that together had presented an empirical perspective of the internationalization process. The analysis and quarrel of the results understand the description and the interpretation of the one of the information through the technique of analyzes of content. Initially the historical of the exportation of fruits of the Rio Grande do Norte with the focus in the region Açu/Mossoró is presented and after that the information of the Finobrasa are presented as base of the study. The main events are identified that had constituted the phases of the strategical model of the company. It was observed that the dimensions most excellent amongst those proclaimed by the School of Uppsala had been the learning, staffs and the step-starts is sufficiently gifts in the reality of the company, as well as the aspects of strategical alliances since the consolidated relationship of the Vicunha Group create a more solid trajectory in the international market allied the conditions created windows of marked . One understands, therefore, that the investigated process still has base the theoretical theories of the internationalization strategies corroborating for the theoretical convergence of the rules proclaimed for the theory of the dependence of resources.

The object of this study is the organizational management, particularly the relational processenvironment organization focused on the survival of the space Department of the Arts and Crafts Mestre Raimundo Cardoso linked to the structural arrangement of the Liceu do Paracuri.. Aimed to understand the ways of organizational survival, from the actors' perception of the Center for Arts Career Workshops and Lais Aderne, with investments that discuss the theoretical models of management, institutional theory, cultural organization and institutionalization of public education requirement of the municipal light LDB. (1996) used a qualitative approach with a view to RICHARDSON (1985). The data generated were analyzed based on the technique of content analysis, the thematic type [categorical] Bardin (1977). The results indicate that the institutionalization of the arrangement of the Liceu do Paracuri emerges meet the legal requirement of the autonomy of municipal educational administration under the aegis of sustainable development, quality of life and basic education from the municipal Hélio Gueiros (1993-1996 ). More specifically the Center for Arts and Crafts Laís Aderne, the unit of analysis, the subjects said that this space is designed as a link between the demands of school and community searching through interdisciplinary activities educate and train manpower mainly potter. They did mention the existence of institutional factors (history, culture, habits, values) represent a strong socio-cultural element to the actors belonging to the core that guides behavior and actions of these individuals, fueled by a sense of hope, inclusion of future artisans in culture ceramist. It made a shared management, the existence of a unique work through cultural revival. However, over the course of time, the core is faced with dilemmas of managing transitions mainly regarding governmental, technological beyond endurance by the craftsmen for the optimization of their work. The conclusion - that the paths chosen for the organizational survival of the core meaning and guiding their actions in the systematization of conduct, representations, memories and traditions through habits and choices of consensus, the viewpoint of the actors

Apesar do amplo crescimento de iniciativas de educação em empreendedorismo nas últimas décadas, não existe ainda consenso quanto à eficácia destas ações, quer em termos de resultados económicos, quer no desenvolvimento de caraterísticas pessoais. A heterogeneidade de objetivos, e público-alvo e a não existência de métodos bem definidos e padronizados de avaliação, dificultam a obtenção de um entendimento geral sobre este fenómeno. Para além disso, muitos dos estudos apresentam uma série de limitações metodológicas e tendem a concentrar-se no contexto americano. Para colmatar estas lacunas, a presente investigação assume como propósito geral analisar a eficácia da educação em empreendedorismo no desenvolvimento da intenção e comportamento empreendedor, através de três unidades de análise: alunos e ex-alunos de uma unidade curricular de empreendedorismo e empreendedores de negócios nascentes. É utilizado uma metodologia mista: quantitativa, para as unidades de análise um e dois, e qualitativa, para a terceira unidade de análise. Os resultados demonstram que a educação em empreendedorismo não aumenta a intenção empreendedora dos alunos, nem o comportamento empreendedor dos ex-alunos. No entanto, verifica-se que a perceção de controlo do comportamento, o conhecimento relativo para o empreendedorismo e o contexto institucional (ou seja, a forma como os alunos internalizam os instrumentos e iniciativas de apoio ao empreendedorismo) aumentam com a participação na unidade curricular. Também, a educação em empreendedorismo é essencial na fase de arranque da própria empresa dotando os empreendedores de conhecimentos e competências que lhes permitem ter um maior controlo e confiança sobre a realização de todo o processo inerente à criação e desenvolvimento de uma ideia de negócio. Este estudo, ao utilizar uma abordagem integrada para a educação em empreendedorismo, permite compreender as diferenças que se devem considerar quando se planeia um programa deste tipo. Por conseguinte, os objetivos de um programa de empreendedorismo devem ser ajustados aos diferentes públicos-alvo, sendo importante perceber se os destinatários participam de forma voluntária ou obrigatória.

This paper analyzes the dynamics ofthe American Depositary Receipt (ADR) of a Colombian bank (Bancolombia) in relation to its pricing factors (underlying (preferred) shares price, exchange rate and the US market index). The aim is to test if there is a long-term relation among these variables that would imply predictability. One cointegrating relation is found allowing the use of a vector error correction model to examine the transmission of shocks to the underlying prices, the exchange rate, and the US market index. The main finding of this paper is that in the short run, the underlying share price seems to adjust after changes in the ADR price, pointing to the fact that the NYSE (trading market for the ADR) leads the Colombian market. However, in the long run, both, the underlying share price and the ADR price, adjust to changes in one another.

Research demonstrates that parental involvement positively impacts student achievement and enhances targeted instruction. Notably, however, little research currently exists on how schools involve parents in Response to Intervention (RTI), a framework for implementing targeted, tiered, research-based instruction. The purpose of this study was to interview selected parents, teachers, RTI specialists, and principals in three Title I elementary schools in one school district, plus one district-level administrator, in order to examine how elementary schools currently involve parents in RTI prereferral interventions, and to understand the factors that might facilitate or challenge such parent involvement. I employed a comparative case study qualitative design with each elementary school as the main unit of analysis. I conducted individual, in-depth interviews that lasted approximately 45-60 minutes with a total of 33 participants across the three school sites, including 11 parents, 12 teachers, and six RTI specialists, three principals, and one district-level administrator. I also analyzed documents related to RTI processes that are available through websites and participants. I used Strauss and Corbin’s (1998) three-step scheme for thematic/grounded theory analysis, and Atlas.ti as the electronic tool for management and analysis. Analyses of the data revealed that personnel across the sites largely agreed on how they explain RTI to parents and notify parents of student progress. Parents mostly disagreed with these accounts, stating instead that they learn about RTI and their child’s progress by approaching teachers or their own children with questions, or by examining report cards and student work that comes home. Personnel and parents cited various challenges for involving parents in RTI. However, they all also agreed that teachers are accessible and willing to reach out to parents, and that teachers already face considerable workloads. It appears that no district- or school-wide plan guides parent involvement practices in RTI at any of the three schools. Finally, I present a discussion of findings; implications for teachers, RTI implementation leaders, and Title school leaders; study limitations; and possibilities for future research.
