Frequência dos antígenos eritrocitários do sistema AB em felinos domésticos no estado da Paraíba

Objetivou-se com este estudo determinar a frequência de antígenos eritrocitários do sistema AB em felinos domésticos da Paraíba, Brasil. Foram selecionados aleatoriamente 178 gatos, clinicamente saudáveis, sem pré-requisitos quanto a sexo ou raça, com peso corporal acima de 1,5 kg e faixa etária acima de um ano de idade, abordados no ato da consulta ambulatorial em clínicas médicas de pequenos animais distribuídas entre três cidades da Paraíba (João Pessoa, Campina Grande e Patos). A determinação dos tipos sanguíneos foi realizada através do teste de hemaglutinação em tubo de ensaio e, a tipagem reversa foi realizada para as amostras tipos B e AB para confirmação e evidenciação de aloanticorpos naturais. Neste estudo a frequência relativa de antígenos eritrocitários A, B e AB em sua totalidade para felinos sem raça foram 98,1%, 1,21% e 0,69%, respectivamente. Todos os felinos com definição racial foram do tipo sanguíneo A. Diante destes, a probabilidade de ocorrência de reações transfusionais aleatórias obtidas foi de 2,78%, sendo cerca 40% (1,11%) potencialmente fatais. Desta forma, dado o conhecimento da frequência dos diferentes tipos sanguíneos em felinos, de uma determinada região, conclui-se que a tipagem sanguínea e o teste de compatibilidade, são importantes ferramentas que permitem ao médico veterinário tomar medidas preventivas que minimizem riscos de ocorrência de reações transfusionais e isoeletrólise neonatal e, estabelece pré-requisitos a respeito dos riscos de procedimentos hemoterápicos em felinos que circunstancialmente necessitem serem conduzidos de forma aleatória.

The Role of Universities in the Triple Helix model of innovation management within the biotechnology industry, Case example: Turku Science Park Network

Biotechnology has been recognized as the key strategic technology for industrial growth. The industry is heavily dependent on basic research. Finland continues to rank in the top 10 of Europe's most innovative countries in terms of tax-policy, education system, infrastructure and the number of patents issued. Regardless of the excellent statistical results, the output of this innovativeness is below acceptable. Research on the issues hindering the output creation has already been done and the identifiable weaknesses in the Finland's National Innovation system are the non-existent growth of entrepreneurship and the missing internationalization. Finland is proven to have all the enablers of the innovation policy tools, but is lacking the incentives and rewards to push the enablers, such as knowledge and human capital, forward. Science Parks are the biggest operator in research institutes in the Finnish Science and Technology system. They exist with the purpose of speeding up the commercialization process of biotechnology innovations which usually include technological uncertainty, technical inexperience, business inexperience and high technology cost. Innovation management only internally is a rather historic approach, current trend drives towards open innovation model with strong triple helix linkages. The evident problems in the innovation management within the biotechnology industry are examined through a case study approach including analysis of the semi-structured interviews which included biotechnology and business expertise from Turku School of Economics. The results from the interviews supported the theoretical implications as well as conclusions derived from the pilot survey, which focused on the companies inside Turku Science Park network. One major issue that the Finland's National innovation system is struggling with is the fact that it is technology driven, not business pulled. Another problem is the university evaluation scale which focuses more on number of graduates and short-term factors, when it should put more emphasis on the cooperation success in the long-term, such as the triple helix connections with interaction and knowledge distribution. The results of this thesis indicated that there is indeed requirement for some structural changes in the Finland's National innovation system and innovation policy in order to generate successful biotechnology companies and innovation output. There is lack of joint output and scales of success, lack of people with experience, lack of language skills, lack of business knowledge and lack of growth companies.

Leptospirose bovina no Estado da Paraíba: prevalência e fatores de risco associados à ocorrência de propriedades positivas

Foram determinadas as prevalências de propriedades positivas e de animais positivos e identificados fatores de risco associados à leptospirose em vacas no Estado da Paraíba, Nordeste do Brasil. Foram aleatoriamente selecionadas 2.317vacas com idade ≥ 24 meses, procedentes de 450propriedades. Para o diagnóstico sorológico da infecção por Leptospira spp. foi empregado o teste de soroaglutinação microscópica (SAM), utilizando-se 24 sorovares como antígenos. Uma propriedade foi considerada positiva quando apresentou pelo menos um animal soropositivo. Das 450 propriedades investigadas 398 (89,7%; IC 95% = 86,6-92,2%) apresentaram pelo menos um animal reagente na SAM para qualquer sorovar, e 1.349 (61,1%; IC 95% = 56,6-65,4%) animais foram soropositivos. O sorovar Hardjo foi o mais prevalente nas propriedades e nos animais, com frequências de 58,17% e 54,69%, respectivamente. Propriedade ser localizada no Sertão (odds ratio = 3,20; p = 0,003), presença de animais silvestres (odds ratio =2,89; p=0,005), não resfriar o leite (odds ratio =3,83; p=0,034) e presença de pastos alagados (odds ratio =2,36; p<0,001) foram identificados como fatores de riscos associados à prevalência de propriedades positivas. Conclui-se que a leptospirose encontra-se amplamente difundida em bovinos do Estado da Paraíba, o que reforça a necessidade de intensificação de medidas de prevenção e controle, como a vacinação dos rebanhos. De acordo com os resultados da análise de fatores de risco, sugere-se que o controle sanitário antes da introdução de animais, drenagem de áreas alagadas e melhora nas condições de manejo são importantes medidas para a prevenção da infecção.

En vårdvetenskaplig syntes mellan vårdandets ethos och vårdintensitet

This is a study in the field of caring science. The kinds of knowledge expansion and theoretical formation outlined in this thesis have a hypothetic-deductive design. The synthesizer of caring science between caring ethos and nursing intensity evolves through a hermeneutic movement between understanding and interpretation, in the dialectic tension between thesis and antithesis. The study had three main aims with corresponding research questions. The first aim was to deepen the understanding of caring ethos within the care of older people from the perspective of caring science. The second aim was to deepen the understanding of nursing intensity within the care of older people, again from the perspective of caring science. The third aim of the study was to create a theoretical model describing the synthesizer between the caring ethos and nursing intensity. The synthesizer of caring science between caring ethos and nursing intensity took place in a process of creativity, which resulted in six new patterns of interpretation. Good care is in constant movement and tension between the ethical and the unethical. In order to guarantee the older person of the future dignity, a caring community, and integrity in care, there is a need for an awareness of and responsibility for those entities than can become ethical problems and dilemmas. The model that describes the synthesizer between caring ethos and nursing intensity, consist of four cornerstones such as caring ethics, wishes and anticipations, an ethical manner in words and action, and ethical leadership. Good care based on the values dignity, a caring community, safety, and integrity, receive their legitimacy through ethical awareness, and consent among caregivers. Ethical awareness deepens the understanding of wishes and expectations that may arise as special needs. Care thus requires an awareness of the balance between the patient’s care need and optimal level of nursing intensity. An ethical leadership considers the needs of the patient and accepts nothing but a work situation where optimal nursing intensity and optimal resource allocation makes good care possible.

Levantamento soroepidemiológico para arbovírus em macaco-prego-galego (Cebus flavius) de vida livre no estado da Paraíba e em macaco-prego (Cebus libidinosus) de cativeiro do nordeste do Brasil

Este estudo descreve a primeira investigação de anticorpos para arbovírus em primatas não humanos do Novo Mundo no nordeste brasileiro. No período de março de 2008 a setembro de 2010 foram colhidos soros sanguíneos de 31 macacos-prego-galegos (Cebus flavius) de vida livre na Paraíba e de 100 macacos-prego (Cebus libidinosus) em cativeiro nos estados de Alagoas, Paraíba, Pernambuco, Piauí e Rio Grande do Norte. Para a pesquisa de anticorpos utilizou-se o teste de inibição da hemaglutinação (IH), usando antígenos de 19 diferentes tipos de arbovírus, pertencentes aos gêneros Flavivirus,Alphavirus e Bunyavirus. As amostras de soro foram testadas nas diluições de 1:20 a 1:1280. Dentre as amostras examinadas, todas as de C. flavius foram negativas e 46% das de C. libidinosus em cativeiro apresentaram anticorpos para arbovírus. Foram detectados anticorpos para nove (9/19) arbovírus. Foram observadas 17 reações heterotípicas, para dois ou mais vírus, do gênero Flavivirus, e 15 para o gênero Alphavirus, com títulos variando de 1:20 a 1:1280. Quinze amostras apresentaram reação monotípica para ILHV (n=4), MAYV (n=6), SLEV (n=1), ROCV (n=2), OROV (n=1) e MUCV (n=1). Estes resultados sugerem que houve intensa circulação de arbovírus na população estudada de macacos-prego em cativeiro.

“Valley co-creation” – exploring the emergence of a cultural product in an entrepreneur-driven value network: Case study: Black Weekend festival

The interconnected domains are attracting interest from industries and academia, although this phenomenon, called ‘convergence’ is not new. Organizational research has indeed focused on uncovering co-creation for manufacturing and the industrial organization, with limited implications to entrepreneurship. Although convergence has been characterized as a process connecting seemingly disparate disciplines, it is argued that these studies tend to leave the creative industries unnoticed. With the art market boom and new forms of collaboration riding past the institution-focused arts marketing literature, this thesis takes a leap to uncover the processes of entrepreneurship in the emergence of a cultural product. As a symbolic work of synergism itself, the thesis combines organizational theory with literature in natural sciences and arts. Assuming nonlinearity, a framework is created for analysing aesthetic experience in an empirical event where network actors are connected to multiple contexts. As the focal case in study, the empirical analysis performed for a music festival organized in a skiing resort in the French Alps in March. The researcher attends the festival and models its cocreation process by enquiring from an artist, festival organisers, and a festival visitor. The findings contribute to fields of entrepreneurship, aesthetics and marketing mainly. It is found that the network actors engage in intimate and creative interaction where activity patterns are interrupted and cultural elements combined. This process is considered to both create and destruct value, through identity building, legitimisation, learning, and access to larger audiences, and it is considered particularly useful for domains where resources are too restrained for conventional marketing practices. This thesis uncovered the role of artists and informants and posits that particularly through experience design, this type of skilled individual be regarded more often as a research informant. Future research is encouraged to engage in convergence by experimenting with different fields and research designs, and it is suggested that future studies could arrive at different descriptive results.

Parâmetros anátomo-estruturais de orgãos reprodutivos de ovinos sem raça definida (SRD) nativos do Estado da Paraíba, com e sem bipartição escrotal: estudo do escroto e funículo espermático

Foram utilizados 42 ovinos sem raça definida, divididos segundo a configuração escrotal. Destes animais, 12 foram utilizados na investigação da biometria testicular e histologia da pele escrotal. Os demais foram destinados ao estudo do funículo espermático. Os animais foram agrupados em um grupo de 21 animais sem bipartição escrotal (GEI) e 21 com bipartição escrotal, (GEII), esta não atingindo 50% do comprimento do eixo longitudinal do escroto. Em cada grupo, em 6 animais foram coletados fragmentos da pele do escroto e em 5 do funículo espermáticos, e processados em rotina histológica e analisados em microscopia de luz; e em 10 foram injetados látex na artéria testicular para obtenção de moldes vasculares e obtenção do comprimento da artéria. Quando comparados os grupos GEI e GEII, não foram encontradas diferenças estatísticas significativas (p<0,05) entre a espessura do escroto (epiderme e derme), constituição histológica da pele escrotal, número de glândulas sudoríparas por área, comprimento do funículo espermático ou parâmetros biométricos testiculares. Entretanto, o comprimento total das artérias testiculares do GEI foi maior do que o GEII (p<0,05). Concluiu-se, com base nos parâmetros morfológicos analisados, que a bipartição escrotal em ovinos não influenciou na estrutura da pele, funículo ou biometria testicular quando comparado aos animais que não apresentavam esta característica. Outros estudos merecem atenção para desmistificar o porquê do aparecimento dessa característica em ovinos e se esta característica é ou não desejável para melhoria na produção desses animais em regiões de clima quente.

A cyber security architecture for military networks using a cognitive network approach

Cyber security is one of the main topics that are discussed around the world today. The threat is real, and it is unlikely to diminish. People, business, governments, and even armed forces are networked in a way or another. Thus, the cyber threat is also facing military networking. On the other hand, the concept of Network Centric Warfare sets high requirements for military tactical data communications and security. A challenging networking environment and cyber threats force us to consider new approaches to build security on the military communication systems. The purpose of this thesis is to develop a cyber security architecture for military networks, and to evaluate the designed architecture. The architecture is described as a technical functionality. As a new approach, the thesis introduces Cognitive Networks (CN) which are a theoretical concept to build more intelligent, dynamic and even secure communication networks. The cognitive networks are capable of observe the networking environment, make decisions for optimal performance and adapt its system parameter according to the decisions. As a result, the thesis presents a five-layer cyber security architecture that consists of security elements controlled by a cognitive process. The proposed architecture includes the infrastructure, services and application layers that are managed and controlled by the cognitive and management layers. The architecture defines the tasks of the security elements at a functional level without introducing any new protocols or algorithms. For evaluating two separated method were used. The first method is based on the SABSA framework that uses a layered approach to analyze overall security of an organization. The second method was a scenario based method in which a risk severity level is calculated. The evaluation results show that the proposed architecture fulfills the security requirements at least at a high level. However, the evaluation of the proposed architecture proved to be very challenging. Thus, the evaluation results must be considered very critically. The thesis proves the cognitive networks are a promising approach, and they provide lots of benefits when designing a cyber security architecture for the tactical military networks. However, many implementation problems exist, and several details must be considered and studied during the future work.

Ocorrência de anticorpos anti-Toxoplasma gondii em aves silvestres de três Unidades de Conservação Federais da Paraíba e da Bahia

Resumo: A vigilância e monitoramento de doenças em animais silvestres são imprescindíveis no contexto ambiental e de saúde pública, pois estes animais agem como sentinelas, refletindo alterações ambientais precocemente, o que proporciona maior eficácia no monitoramento ambiental e permite o acesso rápido a informações sobre as condições da área. Neste contexto, as aves são importantes no ciclo biológico do Toxoplasma gondii e na epidemiologia da toxoplasmose, principalmente porque seus tecidos representam importantes fontes de proteína na alimentação de felídeos e humanos. Objetivou-se detectar anticorpos anti-T. gondii, por meio do teste de aglutinação modificada em aves silvestres de três Unidades de Conservação (UC) Federais dos Estados da Paraíba e Bahia. No período de dezembro de 2011 a outubro de 2013 foram capturadas com redes de neblina 222 aves silvestres pertencentes a 67 espécies, 27 famílias e 12 ordens. Após a captura, foi colhido sangue de cada animal e separado o soro, que foi submetido ao Teste de Aglutinação Modificada (MAT≥1:25) utilizando taquizoítos inativados na formalina e 2-mercaptoetanol. Dentre as 222 amostras analisadas, três (1,3%) foram sororreagentes: 1 de 16 (6,2%) pipira-preta Tachyphonus rufus (título 50), 1 de 5 (20%) juriti-gemedeira Leptotila rufaxilla (título 50) e 1 de 1 (100%) caneleiro-enxofre Casiornis fuscus (título 25). Este é o primeiro relato da ocorrência de anticorpos anti-T. gondii nas referidas espécies de aves silvestres de vida livre nas duas UC Federais estudadas.

Detection of Horizontal Two-Phase Flow Patterns Through a Neural Network Model

One of the main problems related to the transport and manipulation of multiphase fluids concerns the existence of characteristic flow patterns and its strong influence on important operation parameters. A good example of this occurs in gas-liquid chemical reactors in which maximum efficiencies can be achieved by maintaining a finely dispersed bubbly flow to maximize the total interfacial area. Thus, the ability to automatically detect flow patterns is of crucial importance, especially for the adequate operation of multiphase systems. This work describes the application of a neural model to process the signals delivered by a direct imaging probe to produce a diagnostic of the corresponding flow pattern. The neural model is constituted of six independent neural modules, each of which trained to detect one of the main horizontal flow patterns, and a last winner-take-all layer responsible for resolving when two or more patterns are simultaneously detected. Experimental signals representing different bubbly, intermittent, annular and stratified flow patterns were used to validate the neural model.

The Influence of Network Competence on Internationalization of SMEs

This study focuses on the relationship between organizational network competence and the internationalization process of small- and medium sized enterprises (SMEs). Over recent decades, the global business environment has become increasingly conducive to internationalization of small firms. A central facilitating factor in the process has been the emergence of networked business relationships between internationalizing firms. Research on SME internationalization has found that certain types of structures and dynamics of business networks allow SMEs access to the resources they need to enter foreign markets. This consequently means that their internationalization often becomes to depend on the networks they are embedded in. However, research so far has mostly ignored the possibility that the organizational ability to develop and manage business network relationships, network competence, may be a major underlying factor in determining how well SMEs can leverage their network relationships to enter foreign markets and consequently may determine in large part how successful their internationalization process turns out to be. This study aims to respond to those gaps, by empirically examining how the development of network competence in internationalizing SMEs influences the internationalization outcomes that they can expect, and how such network competence is conceptualized and developed. Using a mixed methods approach, survey data collected from 298 Finnish SMEs across five industry sectors is first used to examine how levels of network competence are related to internationalization propensity of SMEs and their subsequent international performance, growth and profitability as internationally operating firms. In order to illustrate in more detail the ways in which network competence is conceptualized and how it develops during the internationalization process of an SME, qualitative data from internationally operating Finnish SMEs are used. Longitudinal interview data of an internationalizing Finnish SME is accompanied by data gathered through a series of semistructured interviews of Finnish and Russian managers involved in mutual business relationship dyads. Structurally, this thesis examines the research issue as an article-based dissertation, consisting of five journal and conference publications. Three of these publications are based on the quantitative data, and the remaining two apply the qualitative interview data. The results find several aspects where network competence has a positive influence on the success of internationalizing SMEs, how it develops and what it entails conceptually in this context. Quantitatively, the level of network competence is found to have a positive relationship to various internationalization outcomes, including the propensity of SMEs to enter foreign markets and on their subsequent international performance, their growth and their profitability. Additionally, the positive relationship is divided between the relationship-specific and cross-relational dimension of network competence, in that the influence of the former is relevant for the propensity to internationalize, while the latter is for the growth and profitability of the already internationalized SMEs. Qualitatively, the results suggest, firstly, that the development process of network competence does not necessarily precede the start of the internationalization process, but may occur through a gradual learning process alongside it. And secondly, the results also imply that the conceptualization of network competence by Finnish managers of internationally operating Finnish SMEs is structurally distinct from that of their culturally distinct partner managers in Russia. This study contributes to the literature on SME internationalization in several ways. Firstly, it introduces operationalized organizational competencies to the literature on internationalization of SMEs, which has so far mainly examined the influence of business networking on the internationalization process without having such an organizational viewpoint. Furthermore, this study provides a multi-level analysis of the determinants of successful SME internationalization, by examining various strategic and performance outcomes across the process. These results also contribute to the literature on organizational strategy of internationalizing SMEs, by clarifying how different dimensions of business networking may be optimal in different phases of the internationalization process. Conceptually, the results of this study contribute to the literature on competence development and SME internationalization, by illustrating how the development process of network competence may occur during internationalization process. Thus, they also contribute to the discussion on how SMEs are able to influence the dynamics and structures of their business networks over time. Finally, this study contributes to the literature on the role of culture in the internationalization process, by implying that the cultural background of the manager of the SME may determine whether business networking and network competence is seen as an organizational-level or an individual level capability. The study also includes some additional contributions to the literature on dynamic capabilities in strategic management, and on that of strategic business networks. These include further clarifying the exact nature and tangibility of dynamic capabilities, and being one of the first studies to introduce constructs from both dynamic capabilities and business network literature to the field of international entrepreneurship. And finally, the study also has some contribution on the two streams of literature, in illustrating how both dyadic and network-level capabilities may be relevant, depending on the current strategic goals and market position of the firm. Keywords: network competence, internationalizatio

Performance measurement and management in a collaborative network

This study concerns performance measurement and management in a collaborative network. Collaboration between companies has been increased in recent years due to the turbulent operating environment. The literature shows that there is a need for more comprehensive research on performance measurement in networks and the use of measurement information in their management. This study examines the development process and uses of a performance measurement system supporting performance management in a collaborative network. There are two main research questions: how to design a performance measurement system for a collaborative network and how to manage performance in a collaborative network. The work can be characterised as a qualitative single case study. The empirical data was collected in a Finnish collaborative network, which consists of a leading company and a reseller network. The work is based on five research articles applying various research methods. The research questions are examined at the network level and at the single network partner level. The study contributes to the earlier literature by producing new and deeper understanding of network-level performance measurement and management. A three-step process model is presented to support the performance measurement system design process. The process model has been tested in another collaborative network. The study also examines the factors affecting the process of designing the measurement system. The results show that a participatory development style, network culture, and outside facilitators have a positive effect on the design process. The study increases understanding of how to manage performance in a collaborative network and what kind of uses of performance information can be identified in a collaborative network. The results show that the performance measurement system is an applicable tool to manage the performance of a network. The results reveal that trust and openness increased during the utilisation of the performance measurement system, and operations became more transparent. The study also presents a management model that evaluates the maturity of performance management in a collaborative network. The model is a practical tool that helps to analyse the current stage of the performance management of a collaborative network and to develop it further.

Mapping the Value Network Potential in Cross-sector Collaboration: Case welfare Services for Elderly in Finland

Value network has been studied greatly in the academic research, but a tool for value network mapping is missing. The objective of this study was to design a tool (process) for value network mapping in cross-sector collaboration. Furthermore, the study addressed a future perspective of collaboration, aiming to map the value network potential. During the study was investigated and pondered how to get the full potential of collaboration, by creating new value in collaboration process. These actions are parts of mapping process proposed in the study. The implementation and testing of the mapping process were realized through a case study of cross-sector collaboration in welfare services for elderly in the Eastern Finland. Key representatives in elderly care from public, private and third sectors were interviewed and a workshop with experts from every sector was also conducted in this regard. The value network mapping process designed in this study consists of specific steps that help managers and experts to understand how to get a complex value network map and how to enhance it. Furthermore, it make easier the understanding of how new value can be created in collaboration process. The map can be used in order to motivate participants to be engaged with responsibility in collaboration and to be fully committed in their interactions. It can be also used as a motivator tool for those organizations that intend to engage in collaboration process. Additionally, value network map is a starting point in many value network analyses. Furthermore, the enhanced value network map can be used as a performance measurement tool in cross-sector collaboration.
