Thymic Hypertrophy and Sudden Unexpected Death In Adults âA Retrospective Study Of 56 Autopsy Cases
Authors: Zou Liping , Zhang Ye , Zhu Rong
Published: March 2018

Status thymico-lymphaticus had ever been explained as a cause of sudden death usually in children, but few cases were reported in adults. We sought to determine the relationship between thymic hypertrophy and sudden unexpected death in adult (SUDA), and associated macroscopic and microscopic findings. Adult post mortems from 1984 to 2014 were reviewed and 23 thymic hypertrophy patients without SUDA, 33 thymic hypertrophy patients with SUDA and 172 SUDAs without thymic hypertrophy entered. The data of thymus, lymph nodes, spleen, heart, aorta, and adrenal glands were collected for macroscopic and histological analysis. Ten antibodies were used and applied to 3 children and 46 adult thymus specimens. We found, as an independent factor, thymic hypertrophy increased significantly the risk of SUDA (6.9 folds) in both male and female. Whatâs more, SUDAs associated with thymic hypertrophy were quite younger (22.5 years) than those without it. A majority of patients with hypertrophic thymus had a variable number of accompanied anomalies described as the typical characteristics of status thymico-lymphaticus, but no macroscopic and microscopic findings related to SUDA in patients with thymic hypertrophy. Cytokeratins (CKs) showed distinctly different immunohistochemical expression patterns in individuals who had different death causes and disease background. Instead of a disease entity âstatus thymico-lymphaticusâ is a systematic abnormality with thymic hypertrophy as a feature involving mainly immune and/or cardiovascular system, probably caused by gene mutations.
Pharmaceutical intervention on Ca2+/cAMP signaling interaction: benefits for combating neurodegeneration and diseases related to aging
Authors: Caricati-Neto Afonso , Bueno Bergantin Leandro
Published: March 2018

The pharmaceutical intervention on the interaction between intracellular signaling pathways mediated by Ca2+ and cAMP (Ca2+/cAMP signaling interaction) could bring important benefits for combating neurodegeneration and diseases related to aging. This discovery emerged from classical neurotransmission studies using rodent vas deferens as a model. From classical reports using this model, the concept of Ca2+-dependent processes involved in the neurotransmission (Ca2+ influx triggers muscle contraction and neurotransmitter release) is amply accepted. Thus, Ca2+ channel blockers (CCB) due to reduction of Ca2+ influx through L-type voltage-activated Ca2+ channels (VACC) should reduce neurotransmission. Nonetheless, using this model, some studies performed since 1975 reported that reduction of Ca2+ influx by low concentrations of CCB (verapamil, diltiazem or nifedipine) produced a paradoxical increase of the contractions mediated by sympathetic nerves, a phenomenon known as âcalcium paradoxâ. Recent studies using adrenal chromaffin cells have also demonstrated that CCB caused a paradoxical increase of the catecholamine release. Because these compounds are blocking the L-type VACC, an augmented nerve-mediated response due to increased neurotransmitter release was an unexpected outcome. In 2013, we revealed that the Ca2+/cAMP signaling interaction could properly explain the so-called âcalcium paradoxâ. The original paper published by us in Cell Calcium (2013) has appeared four times in ScienceDirect TOP 25 Hottest Articles lists. In conclusion, these findings may significantly impact on neurodegenerative diseases, thus may stimulate the development of new pharmacological strategies to combat the diseases related to aging.
Comparative Anatomy of Mandibular Neurovascular Canals in Modern Human and Great Apes: A Pilot Study with Cone Beam Computed to Mography
Authors: Corpas Livia , Huang Yan , Mowafey Bassant , Semal Patrick , Liang Xin , Ivo Lambrichts , Constantinus Politis , Reinhilde Jacobs
Published: March 2018

The aim of the present study was to compare mandibular neurovascular canal anatomy in human and great apes by using cone beam computed tomography (CBCT). The anatomical variability of mandibular neurovascular canals (mandibular, incisive and lingual canals) of 129 modern humans and great apes (Homo, Pan and Gorilla) were analyzed by linear measurements on CBCT images. The Kruskal-Wallis non-parametric test and Dunnâs all pairs for joint ranks were applied to compare the variability of mandibular canals among these groups.

Human, Chimpanzee and Gorilla groups showed significant differences in the dimensions of the mandibular canal, mental foramen, incisive canal, lingual canal and anterior mandibular bone width. Bifid mandibular canals and anterior loops were the anatomical variations most frequently observed in the Gorilla. Humans had a larger mental foramen and a distinctive incisive canal. The latter could not be identified in the Gorilla group.

The variability in the anatomy within mandibles of human and non-human primates, shows different forms in the neurovascular structures. In comparison to the mandible of great apes, the incisive canal is suggested to be a feature unique to the human mandible.
Histological Study of Common House Gecko (Hemidactylus frenatus) Regenerated Tail
Authors: Rakhmiyati Rakhmiyati , Luthfi Muhammad Jafar
Published: March 2018

Common house gecko (Hemidactylus frenatus) belongs to suborder Lacertilia that has capacity to shed its tail (autotomy) as a self-defense mechanism. After autotomy, tail regeneration occurs. Axiale skeleton of an original tail is composed of bony vertebrae, whereas the the regenerate one is comprised of cartilaginous tube. The purpose of this study was to determine the histological difference between axial skeleton of the original tail and the regenerate one of the common house gecko. Twenty four individuals consist of twelve common house gecko with original tail and twelve with regenerate tail were used. Microanatomical observations were carried on histological slide of original and regenerated tail stained with Hematoxylin-Eosin and Mallory Acid Fuchsin. The results showed that the original tail comprised of bony vertebrae whereas regenerated tail supported by cartilaginous tube.

Clustering of 18 Local Black Rice Base on Total Anthocyanin
Authors: Kristamtini Kristamtini , Wiranti Endang Wisnu
Published: March 2018

Black rice has a high anthocyanin content in the pericarp layer, which provides a dark purple color. Anthocyanin serve as an antioxidant that control cholesterol level in the blood, prevent anemia, potentially improve the body's resistance to disease, improve damage to liver cells (hepatitis and chirrosis), prevent impaired kidney function, prevent cancer/tumors, slows down antiaging, and prevent atherosclerosis and cardiovascular disease. Exploration results at AIAT Yogyakarta, Indonesia from 2011 to 2014 obtained 18 cultivar of local black rice Indonesia. The names of the rice are related to the color (black, red or purple) formed by anthocyanin deposits in the pericarp layer, seed coat or aleuron. The objective of the study was to classify several types of local black rice from explorations based on the total anthocyanin content. The study was conducted by clustering analyzing the total anthocyanin content of 18 local black rice cultivars in Indonesia. Cluster analysis of total anthocyanin content were done using SAS ver. 9.2. Clustering dendogram shows that there were 4 groups of black rice cultivars based on the total anthocyanin content. Group I consists of Melik black rice, Patalan black rice, Yunianto black rice, Muharjo black rice, Ngatijo black rice, short life of Tugiyo black rice, Andel hitam 1, Jlitheng, and Sragen black rice. Group II consists of Pari ireng, Magelang black hairy rice, Banjarnegara-Wonosobo black rice, and Banjarnegara black rice. Group III consists of NTT black rice, Magelang non hairy black rice, Sembada hitam, and longevity Tugiyo black rice. Group IV consist only one type of black rice namely Cempo ireng. The grouping result indicate the existence of duplicate names among the black rice namely Patalan with Yunianto black rice, and short life Tugiyo with Andel hitam 1 black rice.
De l’image au social : le chemin d’une évolution pour les pratiques en communication interne
Authors: Brulois Vincent , Charpentier Jean-Marie
Published: March 2018

L’entreprise est aux prises avec des complexités organisationnelles, sociales et territoriales de plus en plus fortes qu’une conception de la communication, indexée sur l’image, ne traduit pas. En première ligne, les communicateurs perçoivent la nécessité de s’extraire du cloisonnement par fonction pour jeter des ponts vers une conception plus sociale de la communication. Des frémissements sont perceptibles qui témoignent d’un questionnement et de possibles reconfigurations de l’approche de la communication dans les entreprises. C’est ce que nous ont dit, à leur manière, un certain nombre de directeurs de la communication interrogés depuis octobre 2009. De leurs propos, nous avons tiré des constats (sur la compréhension, sur la juste distance, sur la relation, sur le sens, sur les connaissances nécessaires) qui sont révélateurs d’une recherche d’articulation entre les individus, d’un souci de mettre à distance une approche réductrice de la communication au profit d’une communication au cœur du système social, au cœur du travail.
Les dispositifs de professionnalisation des formations universitaires en communication
Authors: Lambotte François , Lafrance André A. , Coyette Catherine
Published: March 2018

Dans cet article, nous développons une réflexion sur la professionnalisation de la formation universitaire en communication. Après avoir exposé les différentes significations possibles pour la notion de professionnalisation ainsi que les dispositifs pédagogiques s’y référant, nous faisons état de la situation en Belgique, en France ainsi qu’au Canada. Nous dégageons ensuite une série d’enjeux que nous abordons au travers du récit de notre propre dispositif d’enseignement. Le récit retrace la mise en place d’un séminaire de communication interne interactif dans lequel des étudiants canadiens, français et belges collaborent pour la résolution d’un audit de communication interne fictif. Au final, en prenant appui sur le cadre théorique de Wittorski (2012),  notre article se clôture par une discussion sur les plus-values et les limites d’un tel projet tant pour les étudiants que pour les enseignants. Nous concluons que notre dispositif de formation que nous qualifions de « pédagogie active » est en adéquation avec les attentes et recommandations des associations professionnelles. Parallèlement, il préserve chez eux le développement de compétences universitaires. Les étudiants sont notamment amenés à accroître leur savoir-faire tout en élaborant une réflexion critique sur leurs pratiques professionnelles.
Les dérapages des relations publiques
Authors: Dagenais Bernard
Published: March 2018

Un professionnel des relations publiques peut-il échapper aux pressions de ses patrons lorsqu’ils décident de taire la vérité, de construire des scénarios autour de demi-vérités, de pratiquer la désinformation? La réponse est non. Dès lors, le professionnel des relations publiques devient un mercenaire au service de gens sans scrupules, ou se transforme en avocat et défend la cause de ses employeurs sans souci du bien public. Comment empêcher que cette situation perdure? Trop souvent le professionnel des relations publiques doit se soumettre ou se démettre. Pour éviter le dérapage continuel de la profession des relations publiques, il faut absolument que les associations professionnelles acceptent de livrer un combat sur la place publique contre les dérives du métier. Or, rien n’indique qu’elles soient prêtes à livrer ce combat.
La culture créative des organisations comme substrat à l’apprentissage créatif
Authors: Baillargeon Dany
Published: March 2018

La créativité, autant comme acte processuel que comme résultat de ce processus, est un trope fondateur des agences de communication marketing (McFall, 2004, Nixon 2003). Certains avancent même que la créativité serait la raison d’être des agences (Nixon, 2003). Or pour certains, la créativité ne s’apprendrait pas – en témoigne le parcours académique éclectique des créatifs – ou ne s’apprendrait qu’au contact des pairs (Powell, 2006), à travers des dynamiques de production de sens (Drazin, Glynn & Kazanjian, 1999), des frictions entre les différents corps d’emploi (Hirschman, 1989) ou au contact des clients (Cronin, 2004). Cet article a un triple objectif : 1) d’abord proposer une définition opératoire pour mieux saisir cette culture créative ; 2) l’exemplifier à l’aide d’une étude de cas dans une petite agence de onze personnes 3) mettre en relation la notion de culture créative avec celle d’apprentissage et de transmission du savoir créatif. Il s’en dégage que la performativité de l’ethos créatif des employés comme celle de l’agence participent à maintenir cette culture créative autant qu’elle transmet des formes d’apprentissage de qui est et de ce qui est créatif à travers des dynamiques identitaires, l’éducation à faire auprès des clients et l’utilisation de structures de légitimation interne et externe à l’agence.
Creativity, both as a procedural act as well as the result of such a process, is a founding trope of marketing communication agencies (McFall, 2004, Nixon 2003). Some even argue that creativity is the raison d’être of those agencies (Nixon, 2003). But for some, creativity cannot be learned – as shown by the eclectic academic background of creatives – or it could be learned only through being in contact with peers (Powell, 2006), with clients (Cronin, 2004), through the process of creating meaning (Drazin, Glynn & Kazanjian, 1999), or frictions between different job categories (Hirschman, 1989). The goal of this article is threefold: 1) to propose an operational definition of “creative culture” in order to better understand it; 2) to exemplify it using a case study of a small agency 3) to articulate a relationship between the three related concepts: culture, creative learning and transmission of creative knowledge.  The study demonstrates how the performativity of the creative ethos of both employees and agency   interact to maintain this creative culture while indicating who and what is creative, through dynamics of identity, educating clients and the use of internal and external structures of legitimation.
Des communicants en quête de savoirs et de pratiques réflexives dans une entreprise en tension
Authors: Brulois Vincent , Charpentier Jean-Marie , Viers Jacques
Published: March 2018

En 2013, l’AFCI organisait la quatrième formation autour de l’apport des sciences sociales à la communication. Celle-ci s’inscrit dans une réflexion engagée auparavant sur les savoirs nécessaires aux pratiques professionnelles des communicants. Son objectif est de leur proposer des éléments de connaissances, en contrepoint de leurs compétences, afin de penser la communication et d’agir dans une période incertaine. Partant des situations de travail des communicants, il s’agit de pousser plus avant la réflexivité sur leurs pratiques, de les aider à comprendre leurs logiques d’action, à se mettre à distance et d’étayer une posture professionnelle différente. À tout le moins, ces deux expériences montrent des acteurs en réflexion et un besoin de quelque chose en contrepoint d’une formation initiale parfois lointaine, souvent pratique et opérationnelle. Elles permettent en tout cas d’apprécier une dynamique de métier à l’œuvre, déportant les enjeux de la communication de plus en plus du côté du dialogue, du débat, voire de la confrontation avec les acteurs de la société comme avec les salariés. S’impose l’idée qu’un détour par les sciences sociales peut favoriser la compréhension de ce monde en mouvement qu’est l’entreprise. In fine, cela peut nourrir d’autres pratiques professionnelles en communication, moins ancrées sur la belle image et le discours lisse que sur le social.
In 2013, the AFCI organized the fourth training around the contribution of the social sciences to communication. This one joins in a reflection committed previously on the knowledge necessary for the professional practices of the communicators. Its objective is to propose them elements of knowledge, in counterpoint of their skills, to think of the communication and act for the uncertain period. Starting work situations of communicators, it is a question of urging more before the reflexivity on their practices, of helping them to understand their logics of action, to get away and to support a different professional posture. At the very least, these two experiments show actors in reflection and need for something in counterpoint of a sometime distant initial formation. They allow anyway estimating dynamics of job in the work, deporting the stakes in the communication on the side of the dialogue, debate or confrontation with the actors of the society as with the employees. The idea is imperative that a bend by the social sciences can favor the understanding of this world in movement that is the company. In fine, it can feed other professional practices in communication, less anchored on the beautiful image and the smooth speech that on the social.
L’ « animateur de communauté politique »
Authors: Hübner Lena Alexandra
Published: March 2018

Cet article propose une discussion théorique autour de la notion de l’animateur de communauté dans le domaine politique. Plus précisément nous nous intéressons au rôle que ce dernier joue dans l’émergence de débats délibératifs au sein d’échanges ayant lieu sur les pages Facebook de partis politiques allemands. En s’appuyant sur les recherches portant sur les modérateurs de forums politiques et sur la recherche à propos de la gestion de communauté en communication marketing, le texte se questionne sur la relation entre l’animateur de communauté, son public et le parti politique. Ce faisant, trois hypothèses sont élaborées. Premièrement, le statut de l’animateur de communauté au sein de son équipe pourrait jouer un rôle dans le développement des échanges sur les pages en question. Deuxièmement, la modération silencieuse ne favoriserait pas l’émergence de débats. Troisièmement, le maintien de la frontière de l’espace de discussion susciterait des tensions entre internautes et partis politiques. À travers le concept du gatekeeping (contrôle des flux d’information), il est possible de capturer les rapports de force qui se déploient entre la communauté, l’animateur et le parti politique dans ce contexte.
This article reflects a theoretical discussion about the notion of community management in German politics. It shows the role that the community manager plays in exchanges that take place on Facebook pages of political parties. More precisely, the article focuses on the community manager’s influence on the emergence of deliberative debates. Referring to research about moderation of political parties’ discussion forums as well as to marketing and communication studies on community management, this text questions the relation between community manager, its public and the political party. In doing so, three hypotheses are elaborated. First, the community manager’s status within the communication department and the party itself could play a role in the development of exchanges on the pages in question. Second, silent moderation would not favour emergence of debates. Finally, the maintenance of the frontiers defining the sphere of discussion may provoke tensions between the participants and the party. By applying the concept of gatekeeping, we are able to capture the power relations between users, management and political party in this context.

La professionnalisation des référenceurs aux prises avec le changement permanent
Authors: Domenget Jean-Claude , Sire Guillaume
Published: March 2018

Dans le processus de professionnalisation des référenceurs, le changement permanent imposé par Google, loin de remettre en cause la pérennité de la profession, est un facteur clé de la reconnaissance de leur fonction au sein des  organisations et auprès des différents acteurs avec lesquels ils interagissent (clients, collègues, responsables, etc.). En partant du concept de professionnalisation, développé dans le champ de recherche sur la socialisation professionnelle et la construction identitaire, nous décryptons le marché du référencement en tant que système professionnel. Basé sur l’analyse croisée des résultats de deux recherches empiriques, l’une sur les référenceurs en entreprise de presse et l’autre sur les référenceurs dits « pionniers », notre raisonnement vise à expliquer pourquoi le contexte de flou et de changements permanents contribue en grande partie à la reconnaissance et à la légitimation de la profession du référenceur, et pourquoi ce même contexte peut également conduire à une remise en cause du statut des référenceurs et être mobilisé dans le discours de leurs collaborateurs comme un moyen de questionner leur crédibilité. Autrement dit, le contexte d’incertitude a cela de paradoxal qu’il contribue à rendre pérenne la profession des référenceurs tout en empêchant que le processus de professionnalisation ne s’achève.
If we look at the process of professionalization of SEOs, the permanent change imposed by Google does not prevent the profession to be sustainable. Actually, it is a key factor for the recognition of their function within organizations and among people with whom they interact (customers, colleagues, managers, etc.). Starting from the concept of professionalization, developed in both fields of professional socialization and identity building, we describe SEO market as a professional system. Thanks to the comparative analysis of two empirical studies, one about the role played by SEOs within the news publishing companies and the other about the identity of the SEO « pioneers », our aim was to explain why the context of vagueness and permanent changes helps largely to the recognition and legitimation of SEOs’ profession, and why the same context can also lead to question the status of SEOs and their credibility. In other words, the context of uncertainty appears to be paradoxical because, on one hand, it helps making the SEOs’ profession sustainable and, on the other hand, it prevents the professionalization process to be achieved.
Prise de parole publique et professionnalisation de la communication
Authors: Le Bouëdec Annaïck , Douyère David
Published: March 2018

Cet article étudie le mediacoaching entendu comme professionnalisation du conseil à la prise de parole dans l’espace public et médiatique. Il considère les pratiques professionnelles en lien avec les discours qui les légitiment et s’inscrit dans le cadre de l’étude de la professionnalisation de la communication dans l’espace public (Michel, Lépine, Martin-Juchat et al.) et des liens ambigus entre journalisme et communication (Charon, Legavre, Olivesi). Examinant, à partir d’une étude de terrain, les conceptions et le travail d’une agence de conseil auprès de ses clients, comme les représentations de ces derniers, cette recherche fait apparaître que le mediacoach ancre ici son supposé savoir dans le métier de journaliste, exercé précédemment, identité professionnelle légitimante et favorablement perçue par les clients pour la compréhension qu’elle leur donne des perceptions médiatiques qu’ils s’apprêtent à rencontrer. Le mediacoach apparaît dès lors comme un adaptateur médiatique, ou un initié, concourant à la construction du message du porte-parole de l’organisation et à la supposée émancipation (autonomisation) de celui-ci dans sa prise de parole.
This article examines media coaching as an approach to presenting viewpoints in public and in the media. It looks at this activity in relation to the type of discourse that legitimates it, in the framework of professional communication (Michel, Lépine, Martin-Juchat), and with regard to the ambiguity of the connection between communication and journalism (Charon, Legavre, Olivesi). Based on an empirical study of a consultancy and its clients, along with the representations mobilized by the latter, the research demonstrates how a media coach can draw on previous experience as a journalist, which confers authority and is favorably viewed by clients for the insights it gives them into the media. A coach can thus participate in the co-construction of an organization’s messages, and the consequent emancipation, or autonomisation, of its spokespersons.
Que font les communicants pour sauver leur métier ?
Authors: Ivanov Ivan
Published: March 2018

Les métiers de la fonction communication dans les organisations publiques françaises de sécurité sociale ont beaucoup évolué depuis deux décennies. Si dans les entreprises privées, la mise en place des services communication a été accompagnée par une prise de conscience du rôle et de la valeur des métiers de la fonction communication, dans les organisations publiques, les communicants sont toujours en train de chercher une reconnaissance et une légitimité de leur savoir- faire et de leurs compétences. Le manque de règlementation interne et externe et de cadres institutionnels de reconnaissance professionnelle oblige les communicants à chercher des voies pour préserver l’intégrité de leurs services qui est menacée par la réduction de leurs effectifs. Cette recherche s’intéresse à la façon dont les communicants publics tentent de garantir l’existence de leur métier, en projetant une image voulue et valorisée de soi. Dans cette quête de légitimité professionnelle, la métacommunication devient une des missions fondamentales des communicants dans la recherche de reconnaissance de la « typicité » de leur métier.
The every-day activities of the communication practitioners in the French public organizations have evolved deeply for the past two decades. The establishment of the communication departments in the private companies was backed by the growing awareness of its primacy and the increasing strategic role of the communicator’s profession. In contrast, the communication practitioners in the public organizations are still on the quest for recognition of their legitimacy and know-how, because of the lack of internal and institutional regulations and rule-makings. This research aims to investigate the way in which the communication practitioners in the organizations of the public sector attempt to guarantee the existence of their profession through self-work everyday practices. In this struggle for professional legitimacy, the meta-communication becomes one of the fundamental missions of the communication departments in order to acquire recognition of their professional « typicity ».
L’institutionnalisation de la communication publique
Authors: Lasfar Amina , Leroux Pierre
Published: March 2018

La revendication d’un domaine de la « communication publique » constitue une forme d’aboutissement d’un long processus de valorisation d’un domaine de compétence et d’exercice distinct d’autres professions proches et de reconnaissance d’une spécificité et d’un savoir-faire qui justifierait la revendication d’une labellisation en tant que profession. C’est en effet sous les termes de « communication publique » et de « communicants publics » que l’on désigne aujourd’hui en France un secteur d’activités pour l’essentiel constitué de professionnels rattachés aux institutions politiques et administratives. En combinant démarche compréhensive et objectivation, nous reviendrons, dans ce travail, sur les conditions sociopolitiques qui ont permis de poser progressivement, en France, les bases de reconnaissance de l’existence d’une « nouvelle » profession, pour nous intéresser ensuite aux enjeux de l’institutionnalisation des métiers de la communication publique à travers la contribution de la principale association de « professionnels de la communication publique » (Cap’Com), en mettant l’accent sur la portée et les limites de cette action ainsi que les modèles dont elle s’est inspirée pour son travail de légitimation professionnelle.
The identification of a specific field of “Public Communication” marks the end of a long process in which the existence of a set of skills quite distinct from those of other related and/or competing professions has finally been recognised. It also acknowledges the specific area of expertise that justifies its claim to be classed as a “profession”. Indeed, in France today the terms “public communication” and “public communicator” are used to denote a sector of the economy that is composed mainly of professional people working for political and administrative institutions. Approaching the subject comprehensively and objectively, this study examines the socio-political conditions that laid the foundations in France for the gradual recognition of a “new” profession. We then consider the issues surrounding the institutionalisation of public communication professions by looking at the contribution made by the principal association of “public communications professionals” (Cap’Com), while emphasising the extent and limits of its activities and the models that provided the inspiration for its work in placing the profession on a legitimate footing.

Explorando as características da capacidade de inovação de firmas em atividades produtivas de baixa intensidade tecnológica
Authors: Benedet Daniele Mello , Ruffoni Janaina , Reichert Fernanda Maciel
Published: March 2018

O artigo analisa a capacidade de inovação de firmas de baixa intensidade tecnológica, com base no ‘Modelo das Capacidade de Inovação’. O Modelo compreende a capacidade de inovação da firma a partir de quatro outras: desenvolvimento, operação, gestão e transação. Para tanto, foi realizada uma pesquisa de campo em duas firmas agroindustriais da região dos Campos de Cima da Serra no Rio Grande do Sul/Brasil. As firmas investigadas apresentaram as quatro capacidades previstas no modelo, sendo que uma delas se destacou em cada firma: a capacidade de transação na primeira empresa e a de operação na segunda. Não houve destaque para a capacidade de desenvolvimento, como previsto para firmas de baixa intensidade tecnológica, mas isso não significa que as firmas não tenham rotinas que envolvam a inovação. Essa visão mais abrangente da capacidade de inovação, proporcionada pelo modelo utilizado, contribui para complementar os estudos sobre a complexa natureza do processo inovativo nas firmas. Os resultados apontam também para a necessidade de repensar alguns aspectos do modelo e aplicá-lo novamente no contexto low-tech.

A gestão do conhecimento fundamenta-se na compreensão dos processos relevantes para as organizações. É imprescindível que os processos de negócio estejam alinhados com a estratégia organizacional e que a entrega de valor por meio das atividades que geram produtos e serviços seja conhecida. A cadeia de valor identifica essas atividades e as organiza de acordo com o seu foco em agregação de valor, gestão e suporte. A modelagem da cadeia de valor como processo de captura e organização do conhecimento deve ser estudada. Este estudo propõe um modelo de cadeia de valor para o Centro de Desenvolvimento de Sistemas (CDS) do Exército Brasileiro baseada na identificação e análise dos processos da organização. Esta proposta tem como objetivo prover insumos para que a organização coordene e aperfeiçoe a utilização dos seus recursos, garantindo uma gestão do conhecimento efetiva através da compreensão de seus processos e do fluxo de agregação de valor que o modelo apresenta.

Together the voice of nurses worldwide
Authors: Kennedy Annette
Published: March 2018

The world is in a critical period of time in relation to human resources for health. One of the most significant obstacles for achieving health system effectiveness is the availability of a skilled health workforce, particularly nurses. The World Health Organization estimates that there is a significant shortage of nurses all over the world. Nurses are the main professional component of the ‘front line’ staff in the majority of health systems and their contribution is recognised as essential to meeting the Sustainable Development Goals (SDGs), and delivering safe, accessible and effective care. A shortage in the nursing workforce will lead to a failure to maintain or improve health care (Buchan & Aiken, 2008).

Chandler, PT, Greig, M, Comfort, P, and McMahon, JJ. Variability of plyometric and ballistic exercise technique maintains jump performance. J Strength Cond Res 32(6): 1571–1582, 2018—The aim of this study was to investigate changes in vertical jump technique over the course of a training session. Twelve plyometric and ballistic exercise–trained male athletes (age = 23.4 ± 4.6 years, body mass = 78.7 ± 18.8 kg, height = 177.1 ± 9.0 cm) performed 3 sets of 10 repetitions of drop jump (DJ), rebound jump (RJ) and squat jump (SJ). Each exercise was analyzed from touchdown to peak joint flexion and peak joint flexion to take-off. Squat jump was analyzed from peak joint flexion to take-off only. Jump height, flexion and extension time and range of motion, and instantaneous angles of the ankle, knee, and hip joints were measured. Separate 1-way repeated analyses of variance compared vertical jump technique across exercise sets and repetitions. Exercise set analysis found that SJ had lower results than DJ and RJ for the angle at peak joint flexion for the hip, knee, and ankle joints and take-off angle of the hip joint. Exercise repetition analysis found that the ankle joint had variable differences for the angle at take-off, flexion, and extension time for RJ. The knee joint had variable differences for flexion time for DJ and angle at take-off and touchdown for RJ. There was no difference in jump height. Variation in measured parameters across repetitions highlights variable technique across plyometric and ballistic exercises. This did not affect jump performance, but likely maintained jump performance by overcoming constraints (e.g., level of rate coding).

Welding is a manufacturing process of joining components that is dominant in industries that include civil, oil and gas, automotive, etc. Although it has various benefits, welding still causes residual stresses to remain in a component after welding. Residual stresses may result in unexpected failure and may worsen mechanical performance. Common methods to measure residual stresses include hole-drilling and X-ray diffraction and are characterized by their lack of reliability and complicated implementation process. In this study, pulsed eddy current (PEC) is introduced as a promising technique to measure subsurface residual stress in welding. First, the PEC method is calibrated and the correlation between signals and known stresses are identified, and then the residual stress in a welded component is estimated, and finally, the residual stresses measured by PEC were compared to the results obtained by the finite element technique.

Postharvest aflatoxin contamination is a challenging issue that affects peanut quality. Aflatoxin is produced by fungi belonging to the Aspergilli group, and is known as an acutely toxic, carcinogenic, and immune-suppressing class of mycotoxins. Evidence for several host genetic factors that may impact aflatoxin contamination has been reported, e.g., genes for lipoxygenase (PnLOX1 and PnLOX2/PnLOX3 that showed either positive or negative regulation with Aspergillus infection), reactive oxygen species, and WRKY (highly associated with or differentially expressed upon infection of maize with Aspergillus flavus); however, their roles remain unclear. Therefore, we conducted an RNA-sequencing experiment to differentiate gene response to the infection by A. flavus between resistant (ICG 1471) and susceptible (Florida-07) cultivated peanut genotypes. The gene expression profiling analysis was designed to reveal differentially expressed genes in response to the infection (infected vs. mock-treated seeds). In addition, the differential expression of the fungal genes was profiled. The study revealed the complexity of the interaction between the fungus and peanut seeds as the expression of a large number of genes was altered, including some in the process of plant defense to aflatoxin accumulation. Analysis of the experimental data with “keggseq,” a novel designed tool for Kyoto Encyclopedia of Genes and Genomes enrichment analysis, showed the importance of α-linolenic acid metabolism, protein processing in the endoplasmic reticulum, spliceosome, and carbon fixation and metabolism pathways in conditioning resistance to aflatoxin accumulation. In addition, coexpression network analysis was carried out to reveal the correlation of gene expression among peanut and fungal genes. The results showed the importance of WRKY, toll/Interleukin1 receptor–nucleotide binding site leucine-rich repeat (TIR-NBS-LRR), ethylene, and heat shock proteins in the resistance mechanism.

Published: March 2018

The rare, fully mycoheterotrophic Ghost Orchid, Epipogium aphyllum is only visible during its short flowering and fruiting season, which lasts for a few weeks between May and October. Due to the apparent unpredictability of its flowering, decades may pass between subsequent observations at the same locality. The factors affecting timing of flowering in this enigmatic species remain largely unexplored. In Hungary, it is an extremely rare species: between 1924 and 2014 only 25 dated observations from 15 locations are known. Hungary is located on the edge of the species’ distribution area where higher precipitation may occur only in higher regions of mountains. Hence, the spatial and temporal pattern of precipitation might limit the emergence of generative shoots. In this paper we compared rainfall patterns in relation with the Ghost Orchids’ observations to multiannual precipitation averages. The year of flowering and the month preceding flowering (but not the year before flowering and the month of flowering) were characterised by significantly more rainfall than the multi-annual average precipitation. These results suggest that the appearance of the species in Hungary is precipitation-dependent.

Revisión crítica del género Rogiera Planch. (Rubiaceae, Guettardeae) y la validez del género Rovaeanthus Borhidi (Rubiaceae, Rondeletieae)
Authors: Borhidi A. L.
Published: March 2018

The last synthetic treatment of the Rogiera genus was published by D. Lorence in the Flora Mesoamericana (Vol. 4, part 2) based on a polyphyletic concept including two genera of different tribes and leaving the results of the molecular studies out of consideration or misinterpreting them (Lorence 2012). Rovaeanthus has been distinguished at first by Johan Rova upon comparative molecular studies (Rova 1999, Rova et al. 1999, 2002). Micro- and macromorphological studies revealed that the basic differences between Rogiera and Rovaeanthus are in the structure of the flowers and the shape and cell-patterns of the seeds as they were correctly presented and illustrated by Borhidi (2006, 2012) and Borhidi et al. (2004). These are: Rovaeanthus has a special form of corolla-throat, consisting of fleshy ring – as in Rondeletia – and a superposed hairy ring, like in Rogiera. This combination of the corolla-features is unique in the Neotropical Rubiaceae. Anthers are subbasal in Rovaeanthus, dorsifixed in the middle in Rogiera. Ovary disc with naked ring in Rogiera and hairy in Rovaeanthus. Shape and ornamentation of the seeds are completely different in the two genera (see below). In these features there are not any intermediate variation, between the two taxonomic units as it is suggested by Lorence. The present treatment is based on the original strictly monophyletic concept of Rogiera pointed out by Planchon (1849) and detailed by Borhidi (1982) and Borhidi et al. (2004) including into the study all (15) valid species of Rogiera and two species of Rovaeanthus. The separation of the two genera has been confirmed by later, more detailed molecular studies (Manns and Bremer 2010, Rova et al. 2009) establishing that the two genera belong to two different tribes: Rogiera belongs to Guettardeae, while Rovaeanthus is a member of the Rondeletieae tribe. It is important to mention, that Rovaeanthus was originally accepted as a valid genus by the World checklist of Rubiaceae (2006) and later has been re-classified into Rogiera in 2012, under the influence of the Lorence’s inaccurate treatment.
