'Theory', 'hypothesis', 'model' and 'method' in linguistics: Semasiological and onomasiological perspectives The subject of this thesis is the use of generic scientific terms, in particular the four terms 'theory', 'hypothesis', 'model' and 'method', in linguistic research articles written in French and in Finnish. The thesis examines the types of scientific constructs to which these terms are applied, and seeks to explain the variation in the use of each term. A second objective of the thesis is to analyze the relationships among these terms, and the factors determining the choices made by writers. With its focus on the authentic use of generic scientific terms, the thesis complements the normative and theoretical descriptions of these terms in Science Studies and offers new information on actual writing practices. This thesis adheres to functional and usage-based linguistics, drawing its theoretical background from cognitive linguistics and from functional approaches to terminology. The research material consisted of 120 research articles (856 569 words), representing different domains of linguistics and written in French or Finnish (60 articles in each language). The articles were extracted from peer-reviewed scientific journals and were published between 2000 and 2010. The use of generic scientific terms in the material has been examined from semasiological and onomasiological perspectives. In the first stage, different usages related to each of the four central terms were analyzed. In the second stage, the analysis was extended to other terms and expressions, such as 'theoretical framework', 'approach' and ‘claim’, which were used to name scientific constructs similar to the four terms analyzed in the first stage. Finally, in order to account for the writer’s choice among the terms, a mixed methods approach was adopted, based on the results of a previously conducted questionnaire concerning the differences between these terms as experienced by linguists themselves. Despite the general ideal that scientific terms should be carefully defined, the study shows that the use of these central terms is not without ambiguity. What is understood by these terms may vary according to different conceptual and stylistic factors as well as epistemic and disciplinary traditions. In addition to their polysemy, the semantic potentials of these terms are in part overlapping. In most cases, the variation in the use of these terms is not likely to cause serious misunderstanding. Rather, it allows the researcher to express a specific conceptualization of the scientific constructs mentioned in the article. The discipline of linguistics, however, would benefit from a more elaborate metatheoretical discussion.

This dissertation deals with the conceptions of the relationship between science, technology, innovation, development and society. We aimed to analyze the ways to conceive these relations in documents of the Entrepreneurship and Innovation Programme (Proem) of the Federal Technological University of Paraná (UTFPR) and analyze the conceptions of these relations in view of managers and participants of the Program on Campus Cornélio Procópio, locus of research. It is recognized that the concepts of science, technology, innovation and development are polysemic, so varied are the definitions given by different theorists. For the research were characterized these conceptions into two streams, one called traditional or conservative current, which is supported by the classical theories, that is, those that were developed by authors recognized as classics, and the other current, referred to as critical concepts that sustains it are presented by authors recognized as critical, among which houses the Science studies, Technology and Society (CTS). This categorization buoyed analysis of Proem documents and analysis of the statements collected through interviews with three managers of Proem and eleven participants in the Program. As a result of the research, in general, although there is evidence in Proem documents of a social concern in relation to its role in society, it was observed that the program is based on the traditional and hegemonic view on the subject. In the documents analysis, it was noticed that the conceptions arranged CTS studies are present in relation to the multidimensional development concept. However, the texts analyzed, mostly were identified strong indications of thought supported by logical positivism, in propositions that refer to marketing issues, a proposal to generate an entrepreneurial culture guided by the development of technological innovations designed to meet and / or induce market demands, through production methods for popular goods. As for how managers and participants Proem in Campus Cornelius conceive the relationship between science, technology, innovation, development and society, also was identified closer to the classical view, although the respondents have pointed out many times in their speak apparent concern with social issues, like designing the development from a multidimensional view as cover critical studies CTS. The views of the participants, it was possible to link the strengthening of the concept connected to the linear model of development, in which the more it generates science, more is generated technology and more technology therefore produces more wealth, which in turn, the Schumpeterian view, is the basis of social welfare.

One way to do a bibliometric study is to examine each of the records that make up a database, each record and extract key areas that may disclose relevant information about the use of the database and documents in the collection . This article shows how a reference database allows to obtain important data that can reach conclusions that in some cases surprising. For this study we used the following fields of Database Control Documentary Indigenous Nationalities of Costa Rica 1979-2003: author, place of publication, publisher, year, language and support. The database analyzed has two thousand records and was developed in the Winisis. Moreover, analysis of documents was made after processing of the data, which was to export records to Excel software Winisis. After this information extracted from their chosen fields and are held by their respective separate chart or graph to present the results obtained. Furthermore, we show the application of different methods to learn more about the scientific aspects as: the Price Index, the Index of Collaboration This contribution will, first, for (as) students in the course of the race Metric Studies of Library and Information Science, National University, demonstrate and practice what you learned in this area. They may also benefit the (as) professionals from different areas, such as anthropologists (as), sociologists (as), linguists and librarians (as), among others (as).

Uma avaliação das metodologias de análise e recolha de dados aplicadas pelo Programa NOCTUAPortugal é de extrema importância para se apurar se estas são as mais indicadas em estudos de citizen science. Comparou-se os resultados de diferentes metodologias analíticas de estimação das tendências populacionais das espécies de aves noturnas durante o período de realização do Programa NOCTUA-Portugal (análise gráfica simples, modelos lineares generalizados (GLM-Poisson e GLMM), modelos aditivos generalizados (GAM-LOESS e GAM-mgcv) e software TRIM). Analisou-se a metodologia de censo de modo a avaliar o número de registos face à duração dos pontos de escuta, comparar a eficiência do ponto de deteção com outros estudos, variação das respostas ao longo da noite e efeito da época do ano, vento, nebulosidade e luminosidade da lua. Os resultados mostraram que a metodologia analítica mais indicada era o GLMM e que não era necessário realizar nenhum ajuste em particular na metodologia de censo; Trends in nocturnal birds in Portugal Methods and analysis of a volunteer-based monitoring program ABSTRACT: An evaluation of the methodologies of analysis and data collection applied by NOCTUA-Portugal Program is extremely important to determine whether these are the most suitable in citizen science studies. We compared the results of different analytical methodologies to estimate population trends of the species of nocturnal birds during the period of the NOCTUA-Portugal Program (simple graphical analysis, generalized linear models (GLM-Poisson and GLMM), generalized additive models (GAM-LOESS and GAMmgcv) and software TRIM). We analyzed the field methodology to assess the effect of point duration on the number of records, compared the point count efficiency with other sources, the variation of responses throughout the night, the effect of time of year, wind, cloud cover and moon luminosity. The results showed that the most suitable analytical methodology was the GLMM and it was not necessary to make any particular adjustment in the field methodology.

Child sexual abuse (CSA) disclosure is critical for survivor´s psychosocial adjustment later in life. The aim of the present study was to analyze the relationship between attributions of blame for child sexual abuse by the victim and the disclosure of the abuse to parents or caregivers while controlling for characteristics of the abuse. Female college students between 17 and 24 years of age (M = 19.44, SD = 1.64) from a southern Spanish University were surveyed. Of 1547 respondents, 153 (9.90%) reported having suffered some form of CSA before the age of 15. Information about the characteristics of abuse (age of onset, type of abuse suffered, continuity of abuse, and relationship with and age of the perpetrator) and the existence of abuse disclosure by the survivor was obtained from a self-reported questionnaire developed for the present study. The Attributions of Responsibility and Blame Scale (McMillen & Zuravin, 1997) was used to assess attributions made about CSA (self-blame, perpetrator blame and family blame). The results of a logistic regression model was statistically significant, χ² (9) = 43.856, p < .001. The model explained 41% (Nagelkerke R²) of the variance of abuse disclosure and correctly classified 85.6% of cases. Survivor disclosure was 5.50 times more likely to occur when the perpetrator was not a family member (Wald = 8.14, p < .01) and 3.95 times more likely to occur when there was not physical contact with the perpetrator (Wald = 4.30, p < .05). The occurrence of disclosure was also related to increased perpetrator age (Wald = 4.83, p < .05). With regard to the attributions of blame, the occurrence of disclosure was related to lower scores on self-blame (Wald = 6.78, p < .01) and higher scores on family blame (Wald = 9.67, p < .001). However, no relationship was found between perpetrator blame and disclosure of abuse. The results confirm the idea that not only self-blame attributions, but also family blame attributions are critical to the decision of a CSA victim to disclose abuse. The possibility that children who do not disclose abuse have a greater need to deny the occurrence of abuse, or have more confusion about being abused is discussed. Attributions of blame should be taken into serious consideration when evaluating children for possible sexual abuse.

What theoretical framework can help in building, maintaining and evaluating networked knowledge organization resources? Specifically, what theoretical framework makes sense of the semantic prowess of ontologies and peer-to-peer sys- tems, and by extension aids in their building, maintenance, and evaluation? I posit that a theoretical work that weds both for- mal and associative (structural and interpretive) aspects of knowledge organization systems provides that framework. Here I lay out the terms and the intellectual constructs that serve as the foundation for investigative work into experientialist classifi- cation theory, a theoretical framework of embodied, infrastructural, and reified knowledge organization. I build on the inter- pretive work of scholars in information studies, cognitive semantics, sociology, and science studies. With the terms and the framework in place, I then outline classification theory s critiques of classificatory structures. In order to address these cri- tiques with an experientialist approach an experientialist semantics is offered as a design commitment for an example: metadata in peer-to-peer network knowledge organization structures.

The introduction of engineered nanostructured materials into a rapidly increasing number of industrial and consumer products will result in enhanced exposure to engineered nanoparticles. Workplace exposure has been identified as the most likely source of uncontrolled inhalation of engineered aerosolized nanoparticles, but release of engineered nanoparticles may occur at any stage of the lifecycle of (consumer) products. The dynamic development of nanomaterials with possibly unknown toxicological effects poses a challenge for the assessment of nanoparticle induced toxicity and safety.In this consensus document from a workshop on in-vitro cell systems for nanoparticle toxicity testing11Workshop on 'In-Vitro Exposure Studies for Toxicity Testing of Engineered Nanoparticles' sponsored by the Association for Aerosol Research (GAeF), 5-6 September 2009, Karlsruhe, Germany. an overview is given of the main issues concerning exposure to airborne nanoparticles, lung physiology, biological mechanisms of (adverse) action, in-vitro cell exposure systems, realistic tissue doses, risk assessment and social aspects of nanotechnology. The workshop participants recognized the large potential of in-vitro cell exposure systems for reliable, high-throughput screening of nanoparticle toxicity. For the investigation of lung toxicity, a strong preference was expressed for air-liquid interface (ALI) cell exposure systems (rather than submerged cell exposure systems) as they more closely resemble in-vivo conditions in the lungs and they allow for unaltered and dosimetrically accurate delivery of aerosolized nanoparticles to the cells. An important aspect, which is frequently overlooked, is the comparison of typically used in-vitro dose levels with realistic in-vivo nanoparticle doses in the lung. If we consider average ambient urban exposure and occupational exposure at 5mg/m3 (maximum level allowed by Occupational Safety and Health Administration (OSHA)) as the boundaries of human exposure, the corresponding upper-limit range of nanoparticle flux delivered to the lung tissue is 3×10-5-5×10-3μg/h/cm2 of lung tissue and 2-300particles/h/(epithelial) cell. This range can be easily matched and even exceeded by almost all currently available cell exposure systems.The consensus statement includes a set of recommendations for conducting in-vitro cell exposure studies with pulmonary cell systems and identifies urgent needs for future development. As these issues are crucial for the introduction of safe nanomaterials into the marketplace and the living environment, they deserve more attention and more interaction between biologists and aerosol scientists. The members of the workshop believe that further advances in in-vitro cell exposure studies would be greatly facilitated by a more active role of the aerosol scientists. The technical know-how for developing and running ALI in-vitro exposure systems is available in the aerosol community and at the same time biologists/toxicologists are required for proper assessment of the biological impact of nanoparticles.

Scientific reporting and communication is a challenging topic for which traditional study programs do not offer structured learning activities on a regular basis. This paper reports on the development and implementation of a web application and associated learning activities that intend to raise the awareness of reporting and communication issues among students in forensic science and law. The project covers interdisciplinary case studies based on a library of written reports about forensic examinations. Special features of the web framework, in particular a report annotation tool, support the design of various individual and group learning activities that focus on the development of knowledge and competence in dealing with reporting and communication challenges in the students' future areas of professional activity.
