Roadmapping for technology push and partnership: A contribution for open innovation environments

There are several tools in the literature that support innovation in organizations. Some of the most cited are the so-called technology roadmapping methods, also known as TRM. However, these methods are designed primarily for organizations that adopt the market pull strategy of technology-product integration. Organizations that adopt the technology push integration strategy are neglected in the literature. Furthermore, with the advent of open innovation, it is possible to note the need to consider the adoption of partnerships in the innovation process. Thus, this study proposes a method of technology roadmapping, identified as method for technology push (MTP), applicable to organizations that adopt the technology push integration strategy, such as SMEs and independent research centers in an open-innovation environment. The method was developed through action-research and was assessed from two analytical standpoints: externally, via a specific literature review on its theoretical contributions, and internally, through the analysis of potential users` perceptions on the feasibility of applying MTP. The results indicate both the unique character of the method and its perceived implementation feasibility. Future research is suggested in order to validate the method in different types of organizations (C) 2011 Elsevier Ltd. All rights reserved.

Tuotesuunnittelu direktiiviperustaisesti

Onnistuneen tuotekehitysprojektin läpivieminen vaatii huolellisen alkusuunnittelun ennen varsinaista tuotteen kehityksen aloitusta. Projektin läpiviemiseksi esitetään usein malleja joissa tuotekehitysprojektissa edetään yksi vaihe kerrallaan ja siirrytään seuraavaan vasta, kun edellinen on valmis. Tämän perinteisen mallin rinnalle on tullut DFMA-suunnittelu, jossa murretaan kommunikaatiomuuri suunnittelun ja valmistuksen väliltä ja useita vaiheita tehdään samanaikaisesta. Näin saadaan valmistus- ja kokoonpanoystävällisiä tuotteita, joilla tuotteesta saatava kate voidaan maksimoida samalla kun tuotteen laatua saadaan parannettua. Teknisen kehityksen lisäksi on tuotekehitysprosessissa erottamattomana osana direktiivien asettamien vaatimusten huomioon ottaminen. Jo lähes kaikissa tuotteissa on oltava CE-merkintä. CE-merkinnällä tuotteen valmistaja ottaa täyden vastuun siitä, että tuote täyttää sitä koskevien direktiivien asettamat vaatimukset vaatimustenmukaisuudesta. Direktiivien asettamat vaatimukset on hyvä tiedostaa jo tuotteen suunnittelun alkuvaiheista lähtien, jotta nämä osataan ottaa heti huomioon ja jälkikäteen tehtäviltä muutoksilta vältytään. Teknisten ratkaisujen lisäksi tuotteen dokumentoinnilla on suuri rooli vaatimustenmukaisuuden täyttämisessä. Tuotteesta tulee koota tekninen tiedosto, joka sisältää kaikki tarpeelliset dokumentit, joilla tuotteen vaatimustenmukaisuus voidaan todeta. Teknisen tiedoston vaatimukset on hyvä tiedostaa jo suunnittelun alusta lähtien, jotta tarvittavat dokumentit osataan kerätä projektin aikana tekniseen tiedostoon. Tässä työssä kehitettiin peltier-jäähdytin, jollaiselle asiakkailta saadun palautteen perusteella oli markkinoilla tarve. Jäähdyttimen suunnittelussa käytettiin DFMA:n keinoja yksinkertaistamaan kokoonpanoa. Jäähdyttimelle tehtiin vaatimustenmukaisuustarkastelu, missä tarkasteltiin peltier-jäähdytintä koskevien direktiivien asettamia vaatimuksia ja mitä asioita näiden vaatimusten täyttämiseksi tuli huomioida.

Percepção da pessoa surda sobre qualidade da assistência em saúde

A barreira de comunicação existente entre as pessoas surdas e ouvintes prejudicam a participação ativa da pessoa surda na sociedade, uma vez que dificultam a manifestação de suas opiniões e sua interferência direta no processo de construção do conhecimento. Como forma de amenizar as desigualdades, foi promulgada em 2005 uma lei, conhecida como Lei de Libras, que dentre outras coisas, garantem o acesso bilíngue, nas línguas portuguesa e de sinais, aos serviços essenciais de saúde e educação. Este trabalho de pesquisa teve o objetivo de avaliar a percepção da pessoa surda quanto à qualidade das ações e serviços oferecidos nas unidades de saúde públicas, tendo em vista o cumprimento das leis vigentes voltadas para a inclusão da pessoa surda no acesso à saúde pública. Trata-se de um estudo de natureza exploratório-descritiva e enfoque transversal, realizado numa amostra de 15 pessoas surdas portadoras de perda auditiva severa ou profunda, de ambos os sexos (10 homens e 5 mulheres), que se comunicam através da Língua Brasileira de Sinais (Libras), com idade entre 20 a 38 anos, usuárias dos serviços públicos de saúde, que buscaram atendimento em 2014. Foi utilizado um questionário estruturado. Os resultados apresentados evidenciam uma comunicação inadequada entre pacientes e profissionais da saúde, além da falta de intérpretes e de precariedade na estrutura física. Estes fatos, aliados à necessidade de contratação de intérpretes por parte dos usuários, refletem um desvio da responsabilidade do Estado, no que tange ao acesso pleno aos bens e serviços de saúde conforme as leis vigentes.

Evidences Of Endocytosis Via Caveolae Following Blood-brain Barrier Breakdown By Phoneutria Nigriventer Spider Venom.

Spider venoms contain neurotoxic peptides aimed at paralyzing prey or for defense against predators; that is why they represent valuable tools for studies in neuroscience field. The present study aimed at identifying the process of internalization that occurs during the increased trafficking of vesicles caused by Phoneutria nigriventer spider venom (PNV)-induced blood-brain barrier (BBB) breakdown. Herein, we found that caveolin-1α is up-regulated in the cerebellar capillaries and Purkinje neurons of PNV-administered P14 (neonate) and 8- to 10-week-old (adult) rats. The white matter and granular layers were regions where caveolin-1α showed major upregulation. The variable age played a role in this effect. Caveolin-1 is the central protein that controls caveolae formation. Caveolar-specialized cholesterol- and sphingolipid-rich membrane sub-domains are involved in endocytosis, transcytosis, mechano-sensing, synapse formation and stabilization, signal transduction, intercellular communication, apoptosis, and various signaling events, including those related to calcium handling. PNV is extremely rich in neurotoxic peptides that affect glutamate handling and interferes with ion channels physiology. We suggest that the PNV-induced BBB opening is associated with a high expression of caveolae frame-forming caveolin-1α, and therefore in the process of internalization and enhanced transcytosis. Caveolin-1α up-regulation in Purkinje neurons could be related to a way of neurons to preserve, restore, and enhance function following PNV-induced excitotoxicity. The findings disclose interesting perspectives for further molecular studies of the interaction between PNV and caveolar specialized membrane domains. It proves PNV to be excellent tool for studies of transcytosis, the most common form of BBB-enhanced permeability.

Compétences en santé déficientes: obstacle à une prise en charge optimale [Low health literacy: barrier to optimal care].

Health literacy is defined as "the degree to which individuals have the capacity to obtain, process, and understand basic health information and services needed to make appropriate health decisions." Low health literacy mainly affects certain populations at risk limiting access to care, interaction with caregivers and self-management. If there are screening tests, their routine use is not advisable and recommended interventions in practice consist rather to reduce barriers to patient-caregiver communication. It is thus important to include not only population's health literacy but also communication skills of a health system wich tend to become more complex.

Compétences en santé déficientes: obstacle à une prise en charge optimale [Low health literacy: barrier to optimal care].

Les carences en compétences en santé touchent principalement certaines populations à risques en limitant l'accès aux soins, l'interaction avec les soignants et l'autoprise en charge. L'utilisation systématique d'instruments de dépistage n'est pas recommandée et les interventions préconisées en pratique consistent plutôt à diminuer les obstacles entravant la communication patient-soignant. Il s'agit d'intégrer non seulement les compétences de la population en matière de santé mais aussi les compétences communicationnelles d'un système de santé qui se complexifie.

Involvement of gap junctional intercellular communication in the pathophysiology of inflammation

SUMMARY Inflammation has evolved as a mechanism to defend the body against invading microorganisms and to respond to injury. It requires the coordinated response of a large number of cell types from the whole organism in a time- and space-dependent fashion. This coordination involves several cell-cell communication mechanisms. Exchange of humoral mediators such as cytokines is a major one. Moreover, direct contact between cells happens and plays a primordial role, for example when macrophages present antigens to lymphocytes. Contact between endothelial cells and leucocytes occurs when the latter cross the blood vessel barrier and transmigrate to the inflammatory site. A particular way by which cells communicate with each other in the course of inflammation, which at this time starts to gain attention, is the intercellular communication mediated by gap junctions. Gap junctions are channels providing a direct pathway (i.e. without transit through the extracellular space) for the diffusion of small molecules between adjacent cells. This process is known as gap junctional intercellular communication (GJIC). The general aim of this thesis was to study a possible involvement of GJIC in the pathophysiology of inflammation. A first part of the work was dedicated to study the implication of GJIC in the modification of vascular endothelial function by inflammation. In a second part, we were interested in the possible role of GJIC in the transmigration of neutrophil polymorphonuclear leucocytes through the endothelium. The main positive finding of this work is that acute inflammation preferentially modulates the expression of connexin 40 (Cx40), a gap junction protein specifically expressed in vascular endothelium. The modulation could be towards overexpression (aortic endothelium of septic rats) or towards downregulation (acutely inflamed mouse lung). We put a lot of efforts in search of possible functions of these modulations, in two directions: a potential protective role of Cx40 increased expression against sepsis-induced endothelial dysfunction, and a facilitating role of Cx40 decreased expression in neutrophil transmigration. To pursue both directions, it seemed logical to study the impact of Cx40 deletion using knock-out mice. Concerning the potential protective role of Cx40 overexpression we encountered a roadblock as we observed, in the aorta, a Cx40 downregulation in wild type mouse whereas Cx40 was upregulated in the rat. Regarding the second direction and using an in vivo approach, we observed that pulmonary neutrophil transmigration was not affected by the genetic deletion of Cx40. In spite of their negative nature, these results are the very first ones regarding the potential implication of GJIC concerning leucocyte transmigration in vivo. Because this process involves such tight cell-cell physical contacts, the hypothesis for a role of GJIC remains attractive.

Tissue reaction of the EndoREZ in root canal fillings short of or beyond an apical foramenlike communication

This study evaluated the response of periapical tissues to the endodontic sealer EndoREZ in root canal fillings short of or beyond the apical foramenlike communication. Twenty root canals of premolars and incisors of 2 mongrel dogs were used. After coronal access and pulp extirpation, the canals were instrumented up to a size 55 K-file and the apical cemental barrier was penetrated with a size 15 K-file to create an apical foramenlike communication, which was widened to a size 25 K-file. The canals were irrigated with saline at each change of file. The root canals were obturated either short of or beyond the apical foramenlike opening by the lateral condensation of gutta-percha and EndoREZ, originating 2 experimental groups: G1, EndoREZ/short of the apical foramenlike opening, and G2, EndoREZ/beyond the apical foramenlike opening. The animals were killed by anesthetic overdose 90 days after endodontic treatment. The individual roots were obtained and serial histological sections were prepared for histomorphological analysis (H&E and Brown and Brenn techniques) under light microscopy. The following parameters were examined: closure of the apical foramenlike communication and apical opening of accessory canals, apical cementum resorptions, intensity of the inflammatory infiltrate, presence of giant cells, and thickness and organization of the apical periodontal ligament. Each parameter was scored 1 to 4, 1 being the best result and 4 the worst. Data were analyzed statistically by the Wilcoxon nonparametric tests (P = .05). Comparing the 2 groups, the best result (P = .05) was obtained with root canal filling with EndoREZ short of the apical foramenlike opening. In conclusion, limiting the filling material to the root canal space apically was important to determine the best treatment outcome when EndoREZ was used as the sealer.

Interactions of inhaled nanoparticles with the alveolar-capillary barrier of the human respiratory tract

In dieser Arbeit wurden zytotoxische Effekte sowie die inflammatorische Reaktionen des distalen respiratorischen Traktes nach Nanopartikelexposition untersucht. Besondere Aufmerksamkeit lag auch auf der Untersuchung unterschiedlicher zellulärer Aufnahmewege von Nanopartikeln wie z.B. Clathrin- oder Caveolae-vermittelte Endozytose oder auch Clathrin- und Caveolae-unabhängige Endozytose (mit möglicher Beteiligung von Flotillinen). Drei unterschiedliche Nanopartikel wurden hierbei gewählt: amorphes Silica (aSNP), Organosiloxan (AmorSil) und Poly(ethyleneimin) (PEI). Alle unterschiedlichen Materialien gewinnen zunehmend an Interesse für biomedizinische Forschungsrichtungen (drug and gene delivery). Insbesondere finden aSNPs auch in der Industrie vermehrt Anwendung, und stellen somit ein ernstzunehmendes Gesundheitsrisiko dar. Dieser wird dadurch zu einem begehrten Angriffsziel für pharmazeutische Verabreichungen von Medikamenten über Nanopartikel als Vehikel aber bietet zugleich auch eine Angriffsfläche für gesundheitsschädliche Nanomaterialien. Aus diesem Grund sollten die gesundheitsschädigenden Risiken, sowie das Schicksal von zellulär aufgenommenen NPs sorgfältig untersucht werden. In vivo Studien an der alveolaren-kapillaren Barriere sind recht umständlich. Aus diesem Grund wurde in dieser Arbeit ein Kokulturmodel benutzt, dass die Alveolar-Kapillare Barrier in vivo nachstellt. Das Model besteht aus dem humanen Lungenepithelzelltyp (z.B. NCI H441) und einem humanen microvasculären Endothelzelltyp (z.B. ISO-HAS-1), die auf entgegengesetzten Seiten eines Transwell-Filters ausgesät werden und eine dichte Barriere ausbilden. Die NP Interaktion mit Zellen in Kokultur wurde mit denen in konventioneller Monokultur verglichen, in der Zellen 24h vor dem Experiment ausgesät werden. Diese Studie zeigt, dass nicht nur die polarisierte Eigenschaft der Zellen in Kokultur sondern auch die unmittelbare Nähe von Epithel und Endothelzelle ausschlaggebend für durch aSNPs verursachte Effekte ist. Im Hinblick auf inflammatorische Marker (sICAM, IL-6, IL8-Ausschüttung), reagiert die Kokultur auf aSNPs empfindlicher als die konventionelle Monokultur, wohingegen die Epithelzellen in der Kokultur auf zytotoxikologischer Ebene (LDH-Ausschüttung) unempfindlicher auf aSNPs reagierten als die Zellen in Monokultur. Aufnahmestudien haben gezeigt, dass die Epithelzellen in Kokultur entschieden weniger NPs aufnehmen. Somit zeigen die H441 in der Kokultur ähnliche epitheliale Eigenschaften einer schützenden Barriere, wie sie auch in vivo zu finden sind. Obwohl eine ausreichende Aufnahme von NPs in H441 in Kokultur erreicht werden konnte, konnte ein Transport von NPs durch die epitheliale Schicht und eine Aufnahme in die endotheliale Schicht mit den gewählten Inkubationszeiten nicht gezeigt werden. Eine Clathrin- oder Caveolae-vermittelte Endozytose von NPs konnte mittels Immunfluoreszenz weder in der Mono- noch in der Kokultur nachgewiesen werden. Jedoch zeigte sich eine Akkumulation von NPs in Flotillin-1 und-2 enthaltende Vesikel in Epithelzellen aus beiden Kultursystemen. Ergebnisse mit Flotillin-inhibierten (siRNA) Epithelzellen, zeigten eine deutlich geringere Aufnahme von aSNPs. Zudem zeigte sich eine eine reduzierte Viabilität (MTS) von aSNP-behandelten Zellen. Dies deutet auf eine Beteiligung von Flotillinen an unbekannten (Clathrin oder Caveolae -unabhängig) Endozytosemechanismen und (oder) endosomaler Speicherung. Zusammenfassend waren die Aufnahmemechanismen für alle untesuchten NPs in konventioneller Monokultur und Kokultur vergleichbar, obwohl sich die Barriereeigenschaften deutlich unterscheiden. Diese Arbeit zeigt deutlich, dass sich die Zellen in Kokultur anders verhalten. Die Zellen erreichen hierbei einen höheren Differenzierungsgrad und eine Zellkommunikation mit anderen relevanten Zelltypen wird ermöglicht. Durch das Einbringen eines dritten relevanten Zelltyps in die Kokultur, des Alveolarmakrophagen (Zelllinie THP-1), welcher die erste Verteidigungsfront im Alveolus bildet, wird diese Aussage weiter bekräftigt. Erste Versuche haben gezeigt, dass die Triplekultur bezüglich ihrer Barriereeigenschaften und IL-8-Ausschüttung sensitiver auf z.B. TNF- oder LPS-Stimulation reagiert als die Kokultur. Verglichen mit konventionellen Monokulturen imitieren gut ausgebildete, multizelluräre Kokulturmodelle viel präziser das zelluläre Zusammenspiel im Körper. Darum liefern Nanopartikelinteraktionen mit dem in vitro-Triplekulturmodel aufschlussreichere Ergebnisse bezüglich umweltbedingter oder pharmazeutischer NP-Exposition in der distalen Lung als es uns bisher möglich war.

[The deaf patient--information for a barrier-free conversation with patients in dentistry]

There are about 650,000 people with hearing problems in Switzerland, 10,000 of whom use sign language. About 100,000 people are hard of hearing. Deaf patients require special treatment in the dental office as they have specific communication needs. This community, like many other minority groups, has a sign language and a culture of its own. To prevent misunderstandings it is therefore very important to provide solutions for an enhanced communication. However, guidelines for the communication with deaf dental patients are still missing. Successful communication between deaf patients and dentist is essential for effective care. This paper is concerned with providing background information and introducing recommendations for unrestricted dentist-patient communication. The aim of this article is to improve dentists' knowledge of the appropriate communication with this patient group.

Short communication: differential immunoglobulin transfer during mastitis challenge by pathogen-specific components

Mastitis induced by Escherichia coli is often characterized by severe clinical signs, indicating a more powerful combat of the immune system against the pathogen compared with Staphylococcus aureus infections, which are often represented by chronic and subclinical diseases. The aim of this study was to test the major pathogenic component lipopolysaccharide (LPS) from E. coli and lipoteichoic acid (LTA) from Staph. aureus for their effects on blood-milk barrier integrity and the related transfer of immunoglobulins and lactate from blood into milk. A similar somatic cell count (SCC) increase was achieved by intramammary challenge of 1 quarter of 5 cows with 20 µg of LTA, and 8 cows with 0.2 µg of LPS (maximum log SCC/mL: 7). Milk IgG(1) concentrations increased in LPS- but not in LTA-challenged quarters. Milk IgG(2) concentrations were increased in treated quarters at 3h after LPS, and 6h after LTA challenge. Higher maximum levels of IgG(2) were reached in milk of LPS-treated quarters (173 ± 58 μg/mL) than of LTA-challenged quarters (62 ± 13 μg/mL). Immunoglobulin G(1) and IgG(2) levels did not change in control quarters. l-Lactate concentrations in milk increased 4h after LPS and 5h after LTA challenge and reached higher maximum levels in LPS- (221 ± 48 mg/L) than in LTA-treated quarters (77 ± 18 mg/L). In conclusion, a mammary inflammation on a quantitatively similar level based on SCC increase achieves a more efficient transfer of blood components such as IgG(2) via the blood-milk barrier if induced by LPS from E. coli than by LTA from Staph. aureus. This pathogen-specific difference may play an important role in the cure rate of the respective intramammary infection, which is usually lower in Staph. aureus- than in E. coli-induced mastitis.

Communication: Transition State Theory for dissipative systems without a dividing surface

Transition state theory is a central cornerstone in reaction dynamics. Its key step is the identification of a dividing surface that is crossed only once by all reactive trajectories. This assumption is often badly violated, especially when the reactive system is coupled to an environment. The calculations made in this way then overestimate the reaction rate and the results depend critically on the choice of the dividing surface. In this Communication, we study the phase space of a stochastically driven system close to an energetic barrier in order to identify the geometric structure unambiguously determining the reactive trajectories, which is then incorporated in a simple rate formula for reactions in condensed phase that is both independent of the dividing surface and exact.

Establishing representative no-take areas in the Great Barrier Reef : Large scale implementation of theory on marine protected areas

The Great Barrier Reef Marine Park, an area almost the size , of Japan, has a new network of no-take areas that significantly improves the protection of biodiversity. The new marine park zoning implements, in a quantitative manner, many of the theoretical design principles discussed in the literature. For example, the new network of no-take areas has at least 20% protection per bioregion, minimum levels of protection for all known habitats and special or unique features, and minimum sizes for no-take areas of at least 10 or 20 kat across at the smallest diameter Overall, more than 33% of the Great Barrier Reef Marine Park is now in no-take areas (previously 4.5%). The steps taken leading to this outcome were to clarify to the interested public why the existing level of protection wets inadequate; detail the conservation objectives of establishing new no-take areas; work with relevant and independent experts to define, and contribute to, the best scientific process to deliver on the objectives; describe the biodiversity (e.g., map bioregions); define operational principles needed to achieve the objectives; invite community input on all of The above; gather and layer the data gathered in round-table discussions; report the degree of achievement of principles for various options of no-take areas; and determine how to address negative impacts. Some of the key success factors in this case have global relevance and include focusing initial communication on the problem to be addressed; applying the precautionary principle; using independent experts; facilitating input to decision making; conducting extensive and participatory consultation; having an existing marine park that encompassed much of the ecosystem; having legislative power under federal law; developing high-level support; ensuring agency Priority and ownership; and being able to address the issue of displaced fishers.

Local skirmishes in the contruction of (global) digital business communication technologies

This paper applies Latour’s 1992 translation map as a device to explore the development of and recent conflict between two data standards for the exchange of business information – EDIFACT and XBRL. Our research is focussed in France, where EDIFACT is well established and XBRL is just emerging. The alliances supporting both standards are local and global. The French/European EDIFACT is promulgated through the United Nations while a consortium of national jurisdictions and companies has coalesced around the US initiated XBRL International (XII). We suggest cultural differences pose a barrier to co-operation between the two networks. Competing data standards create the risk of switching costs. The different technical characteristics of the standards are identified as raising implications for regulators and users. A key concern is the lack of co-ordination of data standard production and the mechanisms regulatory agencies use to choose platforms for electronic data submission.

Effective knowledge transfer: a terminological perspective - Dismantling the jargon barrier to knowledge about computer security

The research is concerned with the terminological problems that computer users experience when they try to formulate their knowledge needs and attempt to access information contained in computer manuals or online help systems while building up their knowledge. This is the recognised but unresolved problem of communication between the specialist and the layman. The initial hypothesis was that computer users, through their knowledge of language, have some prior knowledge of the subdomain of computing they are trying to come to terms with, and that language can be a facilitating mechanism, or an obstacle, in the development of that knowledge. Related to this is the supposition that users have a conceptual apparatus based on both theoretical knowledge and experience of the world, and of several domains of special reference related to the environment in which they operate. The theoretical argument was developed by exploring the relationship between knowledge and language, and considering the efficacy of terms as agents of special subject knowledge representation. Having charted in a systematic way the territory of knowledge sources and types, we were able to establish that there are many aspects of knowledge which cannot be represented by terms. This submission is important, as it leads to the realisation that significant elements of knowledge are being disregarded in retrieval systems because they are normally expressed by language elements which do not enjoy the status of terms. Furthermore, we introduced the notion of `linguistic ease of retrieval' as a challenge to more conventional thinking which focuses on retrieval results.
