A internet como fonte de informação bibliográfica em química

The internet is an important tool for obtaining information. It offers vast amounts of information ranging from basic to advanced, from general to specific. Nevertheless, its quality cannot be classified or graded. Furthermore, some technical and/or specific information may not be available for free. This work primarily shows the great utility of the internet for getting suitable information in Chemistry and emphasizes open access and quality sites in Chemistry. It directs the reader towards many useful sites within some branches of Chemistry that provide powerful tools of research and study that may not be obtained easily at a library.

Amenzas a través de la telefonía móvil e internet: perfil psicológico y consecuencias emocionales

En los últimos años se ha producido un incremento del uso de la telefonía móvil e Internet con fines intimidatorios o simplemente para amenazar a los iguales en los centros escolares de nuestro país. Con la voluntad de aportar datos que puedan ayudar a su prevención, se ha realizado un estudio de encuesta en el que se ha obtenido información relativa a las amenazas recibidas a través de los nuevos medios de comunicación, es decir, Internet y la telefonía móvil. Los resultados indican que un 23.3% de los estudiantes de los centros públicos de Enseñanza Secundaria Obligatoria de la ciudad de Girona (Cataluña), durante el curso escolar, han recibido vía Internet o telefonía móvil algún mensaje que, por su contenido, ha supuesto una amenaza para su bienestar. Se analizan las consecuenciasemocionales y las estrategias de afrontamiento utilizadas por parte de estos adolescentes

Productivity, Technical eficiency and internationalisation of the Spanish chemical sector

relationship between productivity and international position of Spanish chemical firms in the period 2005-2011. The goal is to determine whether companies that follow and international strategy, either with exports or by investment in foreign countries obtain greater productivity growth than these that do not operate in global market. For this purpose a panel data set with microdata has been created. A preliminary analysis of the evolution of productivity growth in the sector is carried out. The measurement of Total Factor Productivity is performed. With the estimated TFP we analyze the differentials in productivity growth, comparing the effects of export and investment behavior with non-international firms.

Internet-palvelun tuotekehitys musiikkialalla

Tutkielman tarkoituksena on selvittää, kuinka internet-palvelu kehitetään. Palveluiden kehitysprosessia tutkitaan erityisesti palveluiden kehityksen prosessisyklimallin mukaan ja empiirisessä osiossa sovelletaan teoriaosiossa käytyjä asioita musiikkialan yritykseen. Tutkielman pääongelma on, kuinka musiikkialan internet-palvelu kehitetään. Työn analysointimenetelmä on kvalitatiivinen ja aineisto kerätään sähköpostitse teemahaastatteluina. Palveluiden prosessisykli soveltuu hyvin internet-palveluiden kehityksen kuvaamiseen internetin nopeatempoisen muutostahdin takia. Prosessisyklin vaiheisiin kuuluu suunnittelu-, analyysi-, kehitys- ja lanseerausvaiheet. Internetissä kuluttajien ottaminen mukaan kehitysprosessiin on oleellista. Yritysten tulee myös huomioida, että lanseerausprosessiin tulee varata riittävästi resursseja. Jatkossa tutkimuksissa kannattaa keskittyä erityisesti internetin tuomiin erityispiirteisiin palveluiden kehityksen kannalta.

Contextuality in SME Ownership – Studies on Owner-managers’ Ownership Behavior

The purpose of this study is to deepen the understanding of the meaning of ownership in the context of small and medium sized businesses. The research on ownership has increased and widened during the last few years. Ownership is treated increasingly as a psychological phenomenon and it has been noticed that it is common for SME ownermanagers to be mentally linked to their firms. Previous research is suggesting that the central role of an owner-manager in an SME is specifying the concept of SMEs, and that ownership is creating a great heterogeneity within SMEs. This study suggests that there is a variation whitin ownership behaviour of small business owners, and the variation is not totally random or irrational, but following the general patterns of business ownership and of doing business on an SME level. This study is a concept analytical in nature and it builds on the theoretical clarification of the concept of ownership. The theoretical consideration concludes with proposing a definition of ownership: Ownership means a subject’s relatively sustaining position of control in regard to an object. The empirical part of this study consists of five articles, out of which one is conceptual and four are empirical in nature. The notion of contextuality of ownership and the notions of SME characteristics form the basic premise of this study and the theoretical basis for the publications. From the owner-managers point of view, ownership relates the owner also to his or her environment and therefore also to the valuations of the owner-managers. This means that all the dimensions are not equally valued, but certain dimensions in his or her ownership are more important. The presented empirical research is supporting the claim that there is a variation whitin ownership behaviour of small business owners. When bringing the definition of ownership onto a personal and psychological level and into the SME context, it was noticed that ownership is not only a closed system phenomenon occurring between the owner and object owned, but it is also elementarily connected to the environment. Ownership - along with the psychological side of it - is a contextual phenomenon where the fundamental factor is the relatively sustaining position of control with regard to an object. As a contribution of the study, this definition is bringing a new point of view to the discussion on SMEs, SME strategic behaviour and family businesses. The study concludes with pointing out directions for future research.

Venture capital investment on SME

Internet Turvallisuus ja GOST Algoritmit

Tämä tutkimus keskittyy Venäjän kryptografian standardeihin ja niiden toteutukseen sertifioiduissa tuotteissa. Tässä työssä myös pohditaan menetelmiä, jotka parantavat suorituskykyä. Tutkimus jatkuu turvallisuuspalveluiden toimittajien vertailulla niitten saadun sertifikaattimäärän perusteella. Tämä auttaa arvioimaan Venäjän nykyistä markkinatilannetta. Sen lisäksi työssä kuvataan venäläisten algoritmien integraatiota TLS-, PKI- ja IKEv1-protokolleihin. Tavoitteena on protokollien yhteensopivuus erilaisiin tuotteisiin. Diplomityötä jatketaan tutkimalla IKEv2-protokolan integroinnin vaatimuksia. Lopuksi diplomityössä todetaan, että venäläiset algoritmit ovat turvallisia ja standardisointi auttaa ulkomaisia yrityksiä saamaan tarvittavat sertifikaatit.

Uso da internet como um ambiente para discussão de casos clínicos

Criou-se um espaço na internet para a discussão de casos clínicos no website da Sociedade Brasileira de Nefrologia (http://www.sbn.org.br). O objetivo deste trabalho é apresentar o funcionamento deste espaço virtual e os aprimoramentos gerados após sua implantação, em setembro de 2001. Atualmente, 62 casos já foram divulgados e diagnosticados. Todos estão arquivados neste espaço para consulta sem cadastro prévio. A internet mostrou-se também um ambiente propício à discussão anatomoclínica, uma vez que permite a participação de profissionais de centros distantes e sem condição local para este tipo de atividade, tão importante para o contínuo aprendizado da Medicina.
