Current models of word production assume that words are stored as linear sequences of phonemes which are structured into syllables only at the moment of production. This is because syllable structure is always recoverable from the sequence of phonemes. In contrast, we present theoretical and empirical evidence that syllable structure is lexically represented. Storing syllable structure would have the advantage of making representations more stable and resistant to damage. On the other hand, re-syllabifications affect only a minimal part of phonological representations and occur only in some languages and depending on speech register. Evidence for these claims comes from analyses of aphasic errors which not only respect phonotactic constraints, but also avoid transformations which move the syllabic structure of the word further away from the original structure, even when equating for segmental complexity. This is true across tasks, types of errors, and, crucially, types of patients. The same syllabic effects are shown by apraxic patients and by phonological patients who have more central difficulties in retrieving phonological representations. If syllable structure was only computed after phoneme retrieval, it would have no way to influence the errors of phonological patients. Our results have implications for psycholinguistic and computational models of language as well as for clinical and educational practices.

Over the course of the last twenty years there has been a growing academic interest in performance management, particularly in respect of the evolution of new techniques and their resulting impact. One important theoretical development has been the emergence of multidimensional performance measurement models that are potentially applicable within the public sector. Empirically, academic researchers are increasingly supporting the use of such models as a way of improving public sector management and the effectiveness of service provision (Mayston, 1985; Pollitt, 1986; Bates and Brignall, 1993; and Massey, 1999). This paper seeks to add to the literature by using both theoretical and empirical evidence to argue that CPA, the external inspection tool used by the Audit Commission to evaluate local authority performance management, is a version of the Balanced Scorecard which, when adapted for internal use, may have beneficial effects. After demonstrating the parallels between the CPA framework and Kaplan and Norton's public sector Balanced Scorecard (BSC), we use a case study of the BSC based performance management system in Hertfordshire County Council to demonstrate the empirical linkages between a local scorecard and CPA. We conclude that CPA is based upon the BSC and has the potential to serve as a springboard for the evolution of local authority performance management systems.

Although interests inhabit a central place in the multiple streams framework (MSF), interest groups have played only a minor role in theoretical and empirical studies until now. In Kingdon’s original conception, organized interests are a key variable in the politics stream. Revisiting Kingdon’s concept with a particular focus on interest groups and their activities—in different streams and at various levels—in the policy process, we take this argument further. In particular, we argue that specifying groups’ roles in other streams adds value to the explanatory power of the framework. To do this, we look at how interest groups affect problems, policies, and politics. The influence of interest groups within the streams is explained by linking the MSF with literature on interest intermediation. We show that depending on the number of conditions and their activity level, interest groups can be involved in all three streams. We illustrate this in case studies reviewing labor market policies in Germany and chemicals regulation at the European level.

The aim of this contribution is to critically evaluate one of the theoretical approaches used to study the European Union (EU) political system and interest groups activity: the advocacy coalition framework (ACF). ACF considers that the outcome of legislative procedures is influenced by the alignment and role played by advocacy coalitions. This contribution assesses the impact of ACF on our understanding of the influences on the EU policy processes, highlighting the strengths and weaknesses of the approach. The main argument is that the ACF, although very useful in studying the EU political system, shows shortcomings when applied to the study of EU interest groups' performance. The contribution ends with a consideration of future directions for theoretical and empirical ACF research, alone and as part of wider integrated theoretical approaches to understanding the dynamics of influence in the EU. © 2013 Copyright Taylor and Francis Group, LLC.

This single-case study provides a description and explanation of selected adult students' perspectives on the impact that the development of an experiential learning portfolio had on their understanding of their professional and personal lives. The conceptual framework that undergirded the study included theoretical and empirical studies on adult learning, experiential learning, and the academic quality of nontraditional degree programs with a portfolio component. The study employed qualitative data collection techniques of individual interviews, document review, field notes, and researcher journal. A purposive sample of 8 adult students who completed portfolios as a component of their undergraduate degrees participated in the study. The 4 male and 4 female students who were interviewed represented 4 ethnic/racial groups and ranged in age from 32 to 55 years. Each student's portfolio was read prior to the interview to frame the semi-structured interview questions in light of written portfolio documents. ^ Students were interviewed twice over a 3-month period. The study lasted 8 months from data collection to final presentation of the findings. The data from interview transcriptions and student portfolios were analyzed, categorized, coded, and sorted into 4 major themes and 2 additional themes and submitted to interpretive analysis. ^ Participants' attitudes, perceptions, and opinions of their learning from the portfolio development experience were presented in the findings, which were illustrated through the use of excerpts from interview responses and individual portfolios. The participants displayed a positive reaction to the learning they acquired from the portfolio development process, regardless of their initial concerns about the challenges of creating a portfolio. Concerns were replaced by a greater recognition and understanding of their previous professional and personal accomplishments and their ability to reach future goals. Other key findings included (a) a better understanding of the role work played in their learning and development, (b) a deeper recognition of the impact of mentors and role models throughout their lives, (c) an increase in writing and organizational competencies, and (d) a sense of self-discovery and personal empowerment. ^

The present study was concerned with evaluating one basic institution in Bolivian democracy: its electoral system. The study evaluates the impact of electoral systems on the interaction between presidents and assemblies. It sought to determine whether it is possible to have electoral systems that favor multipartism but can also moderate the likelihood of executive-legislative confrontation by producing the necessary conditions for coalition building. ^ This dissertation utilized the case study method as a methodology. Using the case of Bolivia, the research project studied the variations in executive-legislative relations and political outcomes from 1985 to the present through a model of executive-legislative relations that provided a typology of presidents and assemblies based on the strategies available to them to bargain with each other for support. A complementary model that evaluated the state of their inter-institutional interaction was also employed. ^ Results indicated that executive-legislative relations are profoundly influenced by the choice of the electoral system. Similarly, the project showed that although the Bolivian mixed system for legislative elections, and executive formula favor multipartism, these electoral systems do not necessarily engender executive-legislative confrontation in Bolivia. This was mainly due to the congressional election of the president, and the formulas utilized to translate the popular vote into legislative seats. However, the study found that the electoral system has also allowed for anti-systemic forces to emerge and gain political space both within and outside of political institutions. ^ The study found that government coalitions in Bolivia that are promoted by the system of congressional election of the president and the D'Hondt system to allocate legislative seats have helped ameliorate one of the typical problems of presidential systems in Latin America: the presence of a minority government that is blocked in its capacity to govern. This study was limited to evaluating the impact of the electoral system, as the independent variable, on executive-legislative interaction. However, the project revealed a need for more theoretical and empirical work on executive-legislative bargaining models in order to understand how institutional reforms can have an impact on the incentives of presidents and legislators to form coherent coalitions. ^

Chapter 1: Patents and Entry Competition in the Pharmaceutical Industry: The Role of Marketing Exclusivity Effective patent length for innovation drugs is severely curtailed because of extensive efficacy and safety tests required for FDA approval, raising concern over adequacy of incentives for new drug development. The Hatch-Waxman Act extends patent length for new drugs by five years, but also promotes generic entry by simplifying approval procedures and granting 180-day marketing exclusivity to a first generic entrant before the patent expires. In this paper we present a dynamic model to examine the effect of marketing exclusivity. We find that marketing exclusivity may be redundant and its removal may increase generic firms' profits and social welfare. Chapter 2: Why Authorized Generics?: Theoretical and Empirical Investigations Facing generic competition, the brand-name companies some-times launch generic versions themselves called authorized generics. This practice is puzzling. If it is cannibalization, it cannot be profitable. If it is divisionalization, it should be practiced always instead of sometimes. I explain this phenomenon in terms of switching costs in a model in which the incumbent first develops a customer base to ready itself against generic competition later. I show that only sufficiently low switching costs or large market size justifies launch of AGs. I then use prescription drug data to test those results and find support. Chapter 3: The Merger Paradox and R&D Oligopoly theory says that merger is unprofitable, unless a majority of firms in industry merge. Here, we introduce R&D opportunities to resolve this so-called merger paradox. We have three results. First, when there is one R&D firm, that firm can profitably merge with any number of non-R&D firms. Second, with multiple R&D firms and multiple non-R&D firms, all R&D firms can profitably merge. Third, with two R&D firms and two non-R&D firms, each R&D firms prefer to merge with a non-R&D firm. With three or more than non-R&D firms, however, the R&D firms prefer to merge with each other.

Methodological study, in order to validate the content of the nursing diagnosis protection ineffective in patients undergoing hemodialysis. The research took place in two stages, namely: concept analysis and content analysis of the instrument by experts. T he first step was operationalized through an integrative review of the databaes LILACS, CINAHL, PubMed, Scopus and Cochrane, with the key words protection and hemodialysis, in October and November 2013. The sample consisted of 32 articles, which were analyz ed by a c areful reading to identify the sections that correspond ed to the defining attributes , antecedents and consequences of protection in patients undergoing hemodialysis. T he interpretation for the diagnosis of effective protection was made by transpos ing the components of the diagnosis (definition, defining characteristics and related factors) to the denial form . In the second stage, we elaborated an instrument with the components of the nursing diagnostic s studied and proceeded to the analysis conduct ed in April 2014 by 22 specialists in nephrology and in the terminology of the NANDA International, selected by means of th e Lattes Platform . We used the binomial test to assess the proportion of experts who rated each item as appropriate, considering a si gnificance level of 5%. The project was approved by the Ethics Committee of the institution responsible for the research, an opinion on num b er 387 837 and CAAE 18486413.0.0000.5537. The results show that the proposal for the nursing diagnosis of ineffectiv e protection in patients undergoing hemodialysis is: definition - the same as that presented in the NANDA International Taxonomy II, location - domain safety / protection and class injury. Related factors are: Absence of routine vaccines; Non - adherence to care related to vascular access; Non - adherence to infection control measures; Non - adherence to prescribed diet; Non - adherence to drug therapy; Presence of comorbidities; Drug abuse; Immune disorders; Extremes of age; Abnormal blood profiles; Drugs that red uce immunity; and side effects and adverse treatment - related. The defining characteristics are: Presence of invading the bloodstream; Nutritional disorders; Increase in the number of hospitalizations; Uncontrolled dry weight; Infected vascular access; Vasc ular inadequate access; Increased blood pressure; fever; Bleeding disorder; Disability immunity; fatigue; weakness; itching; and maladaptive response to stress. It follows that the identification of the defining attributes, antecedents and consequences inc reased the wealth of vocabulary, allowing the construction of theoretical and empirical definitions for a broader understanding of the concept protection. Furthermore, the study contributed to the enrichment of nursing specific body of knowledge, as well a s in the direction of nursing care for patients undergoing hemodialysis.

This present research focus at the teaching of music in social programs, it discuss about the teaching concepts that permeates the educational-musical practice presents in Serviço de Convivência e Fortalecimento de Vínculos (SCFV), of Complexo Dom Bosco, in Natal-RN. The Objective is to reflect upon the music teaching concepts and the relations between musical knowledge and culture. For this, it was problematized the concepts of music teaching and learning in governmental social projects through theoretical and empirical research. After this step, it was studied the cultural aspects involving the routine in the institutions the influenced the music learning at Serviço de Convivência e Fortalecimento de Vínculos, furthermore, and how these aspects are present in the constitution of the paradigms that involve music teaching. For this, it was used a qualitative approach and a case study as type of research. As data capture tool it was used the ethnographic write, photography, interviews as a Facilitator of music with the students of the program, and video recordings of musical learning situations. Theoretical support it was used authors who study the complexity, culture and music teaching in social projects. Finally, the conclusion is that musical learning, in the SCFV context, is involved of cultural conceptions steeped to the Oratório Dom Bosco space and the same time the Brazilian Social Assistance Policy. Sometimes these concepts are contradictory: discipline, leadership and combat social exclusion refer to dialogical cultural hologram of the institutions involved in the music education process.

De nombreuses études empiriques ont démontré que la qualité des relations parent-enfant est importante pour le développement des fonctions exécutives (FE) des enfants. Cependant, la majorité des études ont porté sur des échantillons de mères ou de pères, mais non des deux. Le présent mémoire contient un article empirique qui poursuit deux buts. Premièrement, l’article a examiné la contribution unique de la qualité des interactions mère-enfant et père-enfant avec leur bambin (toddler) à la prédiction des FE en milieu scolaire. Deuxièmement, l’article a investigué les effets d'interactions entre la qualité des relations mère-enfant et père-enfant. L’étude a été menée auprès de 46 familles intactes (mère-père-enfant). Lorsque les enfants avaient 18 mois, la qualité des interactions mère-enfant et père-enfant a été mesurée par observation de séquences indépendantes de jeu avec le Mutually Responsive Orientation scale. À la maternelle, les problèmes exécutifs des enfants furent rapportés par le professeur à l’aide du Behavior Rating Inventory of Executive Function. Les résultats indiquent que les enfants qui ont des interactions de meilleure qualité avec leur père à 18 mois sont ensuite considérés par leur professeur de maternelle comme ayant moins de déficits exécutifs. Cela suggère que la relation père-enfant peut être un facteur important à considérer en ce qui concerne le développement des FE des enfants. Les implications théoriques et empiriques ainsi que les implications pratiques, notamment celles concernant les professeurs, sont abordées lors de la conclusion de ce mémoire.

This paper aims to analyse a sample of Galician co-ops to verify whether or not it is possible to deduce different financial behaviours among co-op partners from the amount of net-surplus. To this end, our study adds net-surplus to the variation registered in some account entries so that other residual incomes yielded by the co-op may be considered. The distribution of these revenues shows that partners do not usually choose to fully anticipate residual incomes. This reveals that some firms follow a positive net-surplus strategy, which is actually different from the null net-surplus strategy asserted by the classical financial theory. Furthermore, results show that differences between both strategies are statistically significant. This opens a path to future research on determinants explaining why co-op partners voluntarily renounce to anticipating these residual incomes. Such behaviour only arises when yearly accounts render a positive result, thereby making the accounting net-surplus a useful tool to analyse financial information in co-op societies.

The role of the planning practitioner has received considerable attention in a diverse range of theoretical and empirical debates within the broad spectrum of planning scholarship from normative debates surrounding the planner's role in society, to more empirical investigations into the skills, attributes, and evolving nature of planning practitioners. Fundamental questions surrounding the role and purpose of planners have also entered into more mainstream discussions as the democratic nature of the planning system has been consistently undermined by allegations of misconduct, corruption, and incompetence. Despite the broad range of literature and debate which centres on the role of the planner, relatively few studies have explored the views of planning practitioners themselves, making it difficult to judge whether the ideas of planning academics are actually shared by those in the field. In this paper we seek to address this particular gap and argue that such insights are critical in determining the extent to which planning practitioners serve to challenge, maintain, or reinforce existing power imbalances in the planning system. The methodology consists of a series of qualitative interviews with twenty local authority planners working throughout the Greater Dublin Area, Ireland. The results suggest that planners' self-perceptions of their role tend to reflect traditional pluralist and managerialist perspectives. More broadly, the results suggest that the role orientations of contemporary planners are being shaped by dominant discourses in current planning ideology — namely, collaborative and participatory approaches

Environmental friendly renewable energy plays an indispensable role in energy industry development. Foreign direct investment (FDI) in advanced renewable energy technology spillover is promising to improve technological capability and promote China’s energy industry performance growth. In this paper, the impacts of FDI renewable energy technology spillover on China’s energy industry performance are analyzed based on theoretical and empirical studies. Firstly, three hypotheses are proposed to illustrate the relationships between FDI renewable energy technology spillover and three energy industry performances including economic, environmental, and innovative performances. To verify the hypotheses, techniques including factor analysis and data envelopment analysis (DEA) are employed to quantify the FDI renewable energy technology spillover and the energy industry performance of China, respectively. Furthermore, a panel data regression model is proposed to measure the impacts of FDI renewable energy technology spillover on China’s energy industry performance. Finally, energy industries of 30 different provinces in China based on the yearbook data from 2005 to 2011 are comparatively analyzed for evaluating the impacts through the empirical research. The results demonstrate that FDI renewable energy technology spillover has positive impacts on China’s energy industry performance. It can also be found that the technology spillover effects are more obvious in economic and technological developed regions. Finally, four suggestions are provided to enhance energy industry performance and promote renewable energy technology spillover in China.

I sjukhuskorridorerna står flera rum tomma och operationssalar används inte fullt ut. Anledningen är inte att medborgarna blivit friskare, inte heller är det ekonomin som är huvudorsaken, skälet är bristen på sjuksköterskor1. År 2015 publicerades en artikel om att allt fler sjuksköterskor lämnar Falu Lasarett på grund av dess tunga tre skift2. Vid denna studies början ville vi gå till botten med vad som är attraktivt i sjuksköterskeyrket, varför man väljer att bli sjuksköterska när yrket tycks vara kantat av negativa faktorer. Det vi tidigt märkte var att yrket inte endast kunde beskrivas som antingen attraktivt eller oattraktivt. Syftet med studien blev därför att identifiera attraktiva och oattraktiva faktorer i sjuksköterskeyrket. För att nå syftet eftersöktes respondenter via sociala medier där spridningen blev stor och stoppades när nio sjuksköterskor valt att delta. Respondenterna hade anställning på Falu Lasarett och intervjuas med hjälp av processmetoden "attraktivt arbete". Denna metod har varit ett verktyg i insamlandet av teori och empiri, faktorerna har gett oss handfasta sökord och varit användbara för respondenterna att resonera kring. Resultatet visade att respondenterna upplevde att relationer och social kontakt bidrog till yrkets attraktivitet. De ansåg sig även bli stimulerade av det varierande arbetet i form av tankearbete, praktiskt arbete och det resultat de presterade. De förbättringsområden som studien identifierat är föga förvånande; lön, arbetstid, arbetstakt, status, erkänsla, företaget, ledarskap men även faktorn eftertraktad bedömdes som mindre attraktiv då respondenterna ansåg att de endast var eftertraktade på grund av sin yrkestitel. Störst fokus har lagts på ledarskap, en faktor som tidigt identifierades som ett förbättringsområde. Problematiken kring ledarskapet tycks bottna i det faktum att chefsrekryteringar sker internt på arbetsplatsen och att de chefsutbildningar som erbjuds inte räcker till. Studien har för avsikt att identifiera förbättringsområden, ingen intention har funnits om att studien skulle resultera i en handlingsplan. Vi ser ämnet för komplext för att en C-uppsats skulle kunna landa i en lösning på de problem som sjuksköterskeyrket dras med.

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
