The flow of information within modern information society has increased rapidly over the last decade. The major part of this information flow relies on the individual’s abilities to handle text or speech input. For the majority of us it presents no problems, but there are some individuals who would benefit from other means of conveying information, e.g. signed information flow. During the last decades the new results from various disciplines have all suggested towards the common background and processing for sign and speech and this was one of the key issues that I wanted to investigate further in this thesis. The basis of this thesis is firmly within speech research and that is why I wanted to design analogous test batteries for widely used speech perception tests for signers – to find out whether the results for signers would be the same as in speakers’ perception tests. One of the key findings within biology – and more precisely its effects on speech and communication research – is the mirror neuron system. That finding has enabled us to form new theories about evolution of communication, and it all seems to converge on the hypothesis that all communication has a common core within humans. In this thesis speech and sign are discussed as equal and analogical counterparts of communication and all research methods used in speech are modified for sign. Both speech and sign are thus investigated using similar test batteries. Furthermore, both production and perception of speech and sign are studied separately. An additional framework for studying production is given by gesture research using cry sounds. Results of cry sound research are then compared to results from children acquiring sign language. These results show that individuality manifests itself from very early on in human development. Articulation in adults, both in speech and sign, is studied from two perspectives: normal production and re-learning production when the apparatus has been changed. Normal production is studied both in speech and sign and the effects of changed articulation are studied with regards to speech. Both these studies are done by using carrier sentences. Furthermore, sign production is studied giving the informants possibility for spontaneous speech. The production data from the signing informants is also used as the basis for input in the sign synthesis stimuli used in sign perception test battery. Speech and sign perception were studied using the informants’ answers to questions using forced choice in identification and discrimination tasks. These answers were then compared across language modalities. Three different informant groups participated in the sign perception tests: native signers, sign language interpreters and Finnish adults with no knowledge of any signed language. This gave a chance to investigate which of the characteristics found in the results were due to the language per se and which were due to the changes in modality itself. As the analogous test batteries yielded similar results over different informant groups, some common threads of results could be observed. Starting from very early on in acquiring speech and sign the results were highly individual. However, the results were the same within one individual when the same test was repeated. This individuality of results represented along same patterns across different language modalities and - in some occasions - across language groups. As both modalities yield similar answers to analogous study questions, this has lead us to providing methods for basic input for sign language applications, i.e. signing avatars. This has also given us answers to questions on precision of the animation and intelligibility for the users – what are the parameters that govern intelligibility of synthesised speech or sign and how precise must the animation or synthetic speech be in order for it to be intelligible. The results also give additional support to the well-known fact that intelligibility in fact is not the same as naturalness. In some cases, as shown within the sign perception test battery design, naturalness decreases intelligibility. This also has to be taken into consideration when designing applications. All in all, results from each of the test batteries, be they for signers or speakers, yield strikingly similar patterns, which would indicate yet further support for the common core for all human communication. Thus, we can modify and deepen the phonetic framework models for human communication based on the knowledge obtained from the results of the test batteries within this thesis.

Since his inauguration, President Barack Obama has emphasized the need for a new cybersecurity policy, pledging to make it a "national security priority". This is a significant change in security discourse after an eight-year war on terror – a term Obama announced to be no longer in use. After several white papers, reports and the release of the so-called 60-day Cybersecurity Review, Obama announced the creation of a "cyber czar" position and a new military cyber command to coordinate American cyber defence and warfare. China, as an alleged cyber rival, has played an important role in the discourse that introduced the need for the new office and the proposals for changes in legislation. Research conducted before this study suggest the dominance of state-centric enemy descriptions paused briefly after 9/11, but returned soon into threat discourse. The focus on China's cyber activities fits this trend. The aim of this study is to analyze the type of modern threat scenarios through a linguistic case study on the reporting on Chinese hackers. The methodology of this threat analysis is based on the systemic functional language theory, and realizes as an analysis of action and being descriptions (verbs) used by the American authorities. The main sources of data include the Cybersecurity Act 2009, Securing Cyberspace for the 44th Presidency, and 2008 Report to Congress of the U.S. - China Economic and Security Review Commission. Contrary to the prevailing and popularized terrorism discourse, the results show the comeback of Cold War rhetoric as well as the establishment of a state-centric threat perception in cyber discourse. Cyber adversaries are referred to with descriptions of capacity, technological superiority and untrustworthiness, whereas the ‘self’ is described as vulnerable and weak. The threat of cyber attacks is compared to physical attacks on critical military and civilian infrastructure. The authorities and the media form a cycle, in which both sides quote each other and foster each other’s distrust and rhetoric. The white papers present China's cyber army as an existential threat. This leads to cyber discourse turning into a school-book example of a securitization process. The need for security demands action descriptions, which makes new rules and regulations acceptable. Cyber discourse has motives and agendas that are separate from real security discourse: the arms race of the 21st century is about unmanned war.

Background: Eating disorders are serious psychiatric disorders, which usually have their onset in adolescence. Body dissatisfaction and dieting, both common among adolescents, are recognised risk factors for eating disorders. The aim of the present study was to assess the prevalence of eating disorders in the general adolescent population, assess the risk of developing eating disorders in subgroups of dieters, and analyse longitudinal concomitants of incorrect weight perception. Method: A prospective follow-up study on 595 adolescents, aged 15 at baseline, was conducted in western Finland. The study comprised questionnaires directed at the whole study population and subsequent personal interviews with adolescents found to be screen-positive for eating disorders, at both baseline and three-year follow-up. Results: The lifetime prevalence rates for 18 year old females were 2.6 % for anorexia nervosa, 0.4 for bulimia nervosa, and 9.0 % for eating disorder not otherwise specified (EDNOS). No prevalent case of DSM-IV eating disorders was found among the male participants. Eating disorders, as well as depressive symptoms, social anxiety, and low self-esteem, was more prevalent among females who perceived themselves as being overweight, despite being normal or underweight, when compared to females with a correct weight perception. An incorrect weight perception was associated in males with social anxiety. Female adolescents dieting due to psychological distress, rather than vanity or overweight, had a fifteen-fold risk of developing an eating disorder. Conclusions: Eating disorders are common among female adolescents, and adolescents choosing to diet due to psychological distress show a markedly increased risk of developing an eating disorder. Promotion of general well-being as well as the prevention of body dissatisfaction and misdirected dieting, accompanied by early detection and proper treatment of eating disorders, is needed to reduce the incidence of and facilitate recovery in adolescents suffering from eating disorders.

The present study focuses on the zero person constructions both in Finnish and Estonian. In the zero person construction, there is no overt subject and the verb is in the 3rd person singular form: Fin. Tammikuussa voi hiihtää Etelä-Suomessakin. Est. Jaanuaris saab suusatada ka Lõuna-Soomes ‘In January one can ski even in South-Finland’. The meaning of the zero construction is usually considered generic and open. However, the zero may be interpreted as indexically open so that the reference can be construed from the context. This study demonstrates how the zero may be interpreted as referring to the speaker, the addressee, or anybody. The zero person construction in Finnish has been contrasted to the generic pronoun constructions in Indo-European languages. For example, the zero person is translated in English as you or one; in Swedish and German as man. The grammar and semantics of the Finnish zero person construction have been studied earlier to some extent. However, the differences and similarities between Finnish and Estonian, two closely related languages, have not been thoroughly studied before. The present doctoral thesis sheds light on the zero person construction, its use, functions, and interpretation both in Finnish and Estonian. The approach taken is contrastive. The data comes from magazine articles published in Finnish and translated into Estonian. The data consists of Finnish sentences with the zero person and their Estonian translations. In addition, the data includes literary fiction, and non-translated Estonian corpora texts as well. Estonian and Finnish are closely related and in principle the personal system of the two languages is almost identical, nevertheless, there are interesting differences. The present study shows that the zero person construction is not as common in Estonian as it is in Finnish. In my data, a typical sentence with the zero person in both languages is a generic statement which tells us what can or cannot be done. When making generic statements the two languages are relatively similar, especially when the zero person is used together with a modal verb. The modal verbs (eg. Fin. voida ‘can’, saada ‘may’, täytyä ‘must’; Est. võima ‘may’, saama ‘can’, tulema ’must’) are the most common verbs in both Finnish and Estonian zero person constructions. Significant differences appear when a non-modal verb is used. Overall, non-modal verbs are used less frequently in both languages. Verbs with relatively low agentivity or intentionality, such as perception verb nähdä in Finnish and nägema in Estonian, are used in the zero person clauses in both languages to certain extent. Verbs with more agentive and intentional properties are not used in the Estonian zero person clauses; in Finnish their use is restricted to specific context. The if–then-frame provides a suitable context for the zero person in Finnish, and the Finnish zero person may occur together with any kind of verb in conditional if-clause. Estonian if-clauses are not suitable contexts for zero person. There is usually a da-infinitive, a generic 2nd person singular or a passive form instead of the zero person in Estonian counterparts for Finnish if-clauses with zero person. The aim of this study was to analyze motivations for choosing the zero person in certain contexts. In Estonian, the use of the zero person constructions is more limited than in Finnish, and some of the constraints are grammatical. On the other hand, some of the constraints are motivated by the differences in actual language use. Contrasting the two languages reveals interesting differences and similarities between these two languages and shows how these languages may use similar means differently.

Knowledge transfer is a complex process. Knowledge transfer in the form of exporting education products from one system of education to another is particularly complicated, because each system has been developed in a particular context to meet the requirements seen as relevant at each time. National innovation systems are often seen to form an essential framework within which the development of a country, its economy and level of knowledge are considered and promoted. These systems are orientated towards the future, and as such they also provide a framework for the knowledge transfer related to the development of education. In the best of circumstances they are able to facilitate and boost this transfer both from the viewpoint of the provider and the recipient. The leading thought and the idea of the study is that education export is a form of knowledge transfer, which is illustrated by the existing models included. The purpose of this study is to explore, analyze and describe the factors and phenomena related to education export, and more specifically, those related to the experiences and potential of Finnish education export to Chile. For better understanding, of the multiplicity of the issue involved, the current status of education export between Finland and Chile and he existing efforts within the Finnish innovation network will be outlined as well as new forms of co-operation between Finland and Chile in educational matters explored. Several countries have started to commercialize their education system in order to establish themselves as emerging education exporters. Moreover, the demand for education reform is accurate in many developing countries. This offers a good match between Finland and Chile to be the example countries of the research. The main research findings suggest that there are several business areas in education export. These include degrees in education, training services and education technologies for example The factors that influence education export can be divided into four groups, including academic, cultural, political and economic aspects. Challenges to overcome include the lack of product or services to be sold, lack of market and cultural knowledge of the buyer country, financing and lack of suitable pricing model. National innovation systems could be seen as enabling entities for successful education export. The extensive networks that national innovation systems aim to form, could operate as a basis for joining the forces in selling knowledge as well as receiving knowledge in a constructive way.

OBJETIVO: Avaliar a correlação entre o International Consultation on Incontinence Questionnaire - Urinary Incontinence/Short Form (ICIQ-UI/SF) e a Avaliação Urodinâmica (AU) em mulheres com incontinência urinária (IU). MÉTODOS: Foram analisados retrospectivamente dados clínicos, AU e escore do ICIQ-UI/SF de 358 mulheres com IU atendidas em clínica privada. O teste de correlação entre ICIQ-UI/SF e os parâmetros urodinâmicos foi o teste de Spearman. Foi utilizada a curva ROC, com os valores de sensibilidade e especificidade dos escores do ICIQ-UI/SF apresentados pelas pacientes, para identificar o valor do questionário que determinasse a presença da alteração urodinâmica estudada. Para o cálculo do valor p foi utilizado o teste do c² ou exato de Fisher. O nível de significância foi de 5% e o software utilizado para análise foi o SAS versão 9.2. RESULTADOS: As pacientes com IU aos Esforços segundo a AU - IUE urodinâmica - representaram 67,3% do total; aquelas com IUE na AU e Hiperatividade Detrusora (HD) - IUM urodinâmica - 16,2%, e as pacientes com HD isolada - HD - 7,3% do total. As pacientes com AU normal representaram 9,2% do total da amostra. Houve associação significativa entre escore ³14 no ICIQ-UI/SF e as pacientes com IUE urodinâmica e IUM urodinâmica. Pacientes com Pressão de Perda ao Esforço (PPE) £90 cmH2O apresentaram escore ao ICIQ-UI/SF³15. O teste de Spearman mostrou correlação inversa fraca entre o escore e a PPE, porém não mostrou correlação entre esse escore e a Capacidade Cistométrica Máxima (CCM) ou com o volume vesical no primeiro desejo miccional. CONCLUSÃO: Houve associação entre o escore do ICIQ-UI/SF e IUE urodinâmica (isolada ou associada à HD); porém não houve associação com a HD isolada. Quanto menor o valor da PPE, maior o escore total do ICIQ-UI/SF. O ICIQ-UI/SF não foi capaz de discriminar o tipo de IU na população estudada.

PURPOSE: To evaluate the prevalence of women aged 50 years or more who are sexually active and their self-perception with respect to their sexual lives. Associated factors were also assessed. METHODS: A cross-sectional, population-based, self-reported household survey involving 622 Brazilian women aged 50 years or more. Sociodemographic, clinical, and behavioral factors were evaluated. The sexual life self-perception was classified as very good, good, fair, poor, or very poor. Data were analyzed using the χ² test, Fisher's exact test, and Poisson multiple regression analysis. Prevalence ratios and their 95% confidence intervals were also calculated. RESULTS: Of the women in this sample, 228 (36.7%) reported having a sexual life and, of these, 53.5% classified it as very good or good, while 46.5% considered it fair, poor, or very poor. The bivariate analysis indicated that being postmenopausal (p=0.025) and using natural remedies to treat the menopause (p=0.035) were factors associated with the woman classifying their sexual lives as fair, poor, or very poor. Multiple regression analysis showed that more women who had used or were currently using natural remedies for the menopause scored their sexual lives as fair, poor, or very poor. CONCLUSIONS: More than half the women aged 50 years or more in this study were not sexually active. A poorer sexual life self-perception was associated with the use of natural remedies to treat menopausal symptoms. This may indicate a need to improve the way in which these women are evaluated and treated. Women's assessment of their own sexual lives may prove a useful tool in clinical practice.

Social media is a multidimensional marketing and communications channel which can support and enhance a business’ reputation, sales and even longevity. Social media as a business tool encourages an interaction between customers and companies which gives opportunities for a company to better understand their customers, to target them more effectively and to collaborate and create dialogues with them which is not possible through traditional media channels. The aim of a social media strategy is to increase brand awareness, image, loyalty and recognition. The peer networks that social media creates allows a company to disseminate information through loyal customers to new and prospective customers to ultimately increase reach. The purpose of the study is to understand the marketer’s perspective of social media marketing use and how it is currently utilized in marketing and communications activities in Finland. Three companies were interviewed covering fourteen different implementations of social media marketing campaigns. These were then analysed to ascertain the utilization methods and experience gained on recent campaigns in the Finnish market The utilization of social media marketing was analysed using the methods of thematic analysis and inductive and abductive reasoning. Elements and themes were drawn out of the separate interviews to create a framework with which to explore, evaluate and match theories that define social media usage by companies. It became clear from all of the interviews that social media as a tool is most effective when it captures the viewer’s interest through rich and entertaining content. This directed the theoretical research towards Engagement Theory and Content Marketing which look to emphasize the importance of communities, collaboration, interaction, and peer-sharing as the key drivers of a social media marketing campaign.

This study aimed to know the perception of Gir cattle breeders and farm employees about parasitic otitis and practices regarding methods of treatment and control. A questionnaire was applied on specific topics about the disease. The results showed that the otitis occurred in 25 (89.3%) of the 28 farms studied, where the main etiologic agents were the nematodes Rhabditis spp. The majority of the farmers regarded the disease as a serious problem, mainly in cattle older than eight years of age. About half of the respondents did not observe a correlation between season and prevalence of the otitis; however, 30.8% reported an increase of its incidence during the rainy season. In addition to various methods and products for the rhabditiosis treatment, a lack of standardized preventive or curative protocols was found, suggesting insufficient knowledge about control of the disease.
