SummaryObjectives: Second intention wound healing may be impaired by wound and host factors and thus more advanced therapies are required for a fast and satisfactory outcome. Platelet-rich plasma (PRP), rich in growth factors and cytokines essential for tissue repair, could improve wound healing. The purpose of this experimental study was to evaluate the effect of locally injected autologous PRP on second intention healing of acute full-thickness skin defects in dogs.Methods: Three 2x2 cm full-thickness skin defects were created bilaterally on the dorso-lateral area of the trunk of six Beagle dogs. The wounds of one randomly selected side received PRP treatment, whereas the contra-lateral wounds were left untreated (controls). Wound healing was evaluated by planimetry, laser-Doppler flowmetry measurements of tissue perfusion, and histo-logically.Results: The rate of wound healing did not differ significantly between the two groups. Tissue perfusion was significantly higher in the PRP-treated group (p = 0.008) compared to controls on day 10. Histological evaluation revealed a trend towards greater collagen production and a significantly better collagen orientation (p = 0.019) in PRP-treated wounds on day 20.Clinical significance: Locally injected auto-logous PRP does not accelerate the healing process, but increases tissue perfusion and may promote the formation of organized collagen bundles in acute full-thickness skin defects in dogs.

Published: March 2015

Même si les organisations internationales et la littérature existante reconnaissent l’importance des rapports sur la durabilité pour les gouvernements de nos jours, certaines études révèlent que cette question n’a pas reçu l’attention qu’elle mérite et qu’elle doit dès lors être examinée de plus près. Dans le présent article, nous étudions la publication par les gouvernements locaux des informations sur les questions de durabilité, en analysant la relation entre les différents niveaux de divulgation des informations sur la durabilité et certaines variables socioéconomiques, financières et démographiques. Compte tenu du recours accru à l’Internet par les gouvernements, la méthodologie appliquée dans la présente étude consiste à analyser les sites Web de 55 grandes villes espagnoles pour y rechercher 61 éléments recommandés dans les lignes directrices de la Global Reporting Initiative. En appliquant une régression linéaire multiple, nous avons analysé l’influence de treize facteurs sur les rapports sur la durabilité publiés par ces autorités municipales. Les résultats indiquent que les informations sociales sont les plus répandues et que la population inactive a une influence positive sur la divulgation des informations sur la durabilité. Les principaux moyens d’améliorer les pratiques en matière de durabilité consistent à améliorer la divulgation des informations économiques et en matière d’environnement, par la publication de rapports formels sur la durabilité et en améliorant la coordination des informations publiées individuellement par différents départements. Remarques à l’intention des praticiens Les résultats obtenus font ressortir plusieurs questions particulièrement intéressantes pour les gestionnaires. D’une part, la crise financière dans le secteur public a fait ressortir la nécessité de légitimer les actions du gouvernement. De plus, l’incidence de la variable « population inactive » sur la divulgation des informations sur la durabilité indique qu’il existe un lien important entre la structure de la population et la divulgation de ces informations, ce qui fait ressortir la nécessité de considérer l’âge de la population et son évolution au fil du temps comme la raison d’être de la création de rapports spécifiques sur la durabilité. La demande d’informations sur la durabilité de la part du public ne dépend pas du niveau d’impôts payés. Enfin, le niveau d’autonomie des gouvernements locaux n’a aucune influence sur les informations divulguées à propos de leurs engagements en matière de durabilité économique.
L’hybridité au cœur de la gouvernance contemporaine du risque. L’exemple de la sécurité de la chaîne alimentaire en Belgique
Authors: Schiffino Nathalie , Roane Julien 
Published: March 2015

Quelles mutations et défis pour le régulateur public dans un contexte de gouvernance du risque ? Déployant le prisme analytique développé par Jacques Chevallier, la contribution propose d’examiner les mutations du rôle du régulateur public en se focalisant sur le style d’action publique et les instruments de gouvernance. Partant du constat d’hybridité observé dans l’examen du régime de régulation de la sécurité de la chaîne alimentaire en Belgique, la contribution met l’accent sur une double source d’instabilité reflétant les tensions au cœur des valeurs publiques structurant le régime de régulation. La déconstruction de cette hybridité dévoile le caractère négocié et conflictuel des valeurs sous-jacentes à l’action du régulateur public et à son évaluation. Remarques à l’intention des praticiens Partant de constats effectués au cœur du régime de régulation des risques liés à la sécurité de la chaîne alimentaire en Belgique, la contribution pointe les enjeux posés aux régulateurs publics dans le contexte de la gouvernance du risque. Observant le caractère hybride de leur intervention, elle met en évidence deux sources de tension liées au style de leur action et à l’usage des instruments de régulation. S’interrogeant sur les pistes de stabilisation possibles destinées à répondre à ces tensions, trois pistes de réflexion sont pointées pour penser l’ajustement du rôle du régulateur public en soulignant l’importance transversale de l’apprentissage.
La collaboration étendue à la suite des catastrophes du 11 mars au Japon : Implications pour la gestion responsable des catastrophes
Authors: Aoki Naomi 
Published: March 2015

Le 11 mars 2011, un séisme en mer d’une magnitude de 9,0 et un tsunami gigantesque venaient frapper la région de Tohoku au Japon, catastrophe qui a été suivie de la crise nucléaire de Fukushima. Malgré ces malheurs, Tohoku avance et cette expérience extraordinaire doit nous inspirer dans l’étude de la gestion responsable des catastrophes. On a assisté à un phénomène étonnant à la suite des catastrophes, à savoir l’apparition d’une collaboration étendue ( wide-area collaboration) , faisant intervenir les gouvernements national et locaux, afin d’aider les municipalités de Tohoku. Dans la présente étude, nous nous intéressons à cette collaboration dans deux domaines : l’aide sur le plan de la main-d’œuvre et le traitement des débris. Les données empiriques indiquent que l’efficacité de la collaboration étendue dépend de l’efficacité de la collaboration à la fois horizontale (interlocale) et verticale (intergouvernementale) et que la collaboration étendue devrait être ajoutée aux modèles futurs visant à prévoir l’efficacité des processus de restauration et de reconstruction. Remarques à l’intention des praticiens Il serait erroné de penser que nous ne connaîtrons plus de catastrophes de grande ampleur à l’avenir et les questions de collaboration étendue auxquelles est confronté le Japon nous amènent cette fois naturellement à nous interroger sur la façon de définir au mieux la gouvernance collaborative dans le pays. La présente étude répertorie les éléments que les décideurs doivent définir lorsqu’ils mettent en place une collaboration étendue. Nos conclusions semblent généralisables aux États unitaires sujets aux catastrophes disposant d’une gestion des catastrophes décentralisée. Notre étude indique que les systèmes décentralisés dépourvus de plan en matière de collaboration étendue peuvent être dangereux en temps de crise.

Published: March 2015

Purpose:
Akt is a serine/threonine protein kinase and has emerged as a crucial regulator of widely divergent cellular processes, including apoptosis, proliferation, differentiation, and metabolism. Activation of Akt/protein kinase B has been positively associated with human epidermal growth-factor receptor 2 (HER2)/neu overexpression in breast carcinoma and a worse outcome among endocrine treated patients. The Akt signaling pathway currently attracts considerable attention as a new target for effective therapeutic strategies. We therefore investigated the relationship between activation of Akt and clinicopathologic variables including hormone receptor and HER2/neu status.

Methods:
Archival tumor tissues from 100 patients with invasive breast carcinoma were analyzed by immunocytochemistry. This study describes the results of immunocytochemical pAkt expression in breast carcinoma imprints, prepared from cut surfaces of freshly removed tumors. Both nuclear and cytoplasmic expressions were evaluated for pAkt.

Results:
Nuclear and cytoplasmic positive scores of 72% (72/100) and 42% (42/100), respectively, were found. Coexistence of nuclear and cytoplasmic staining was observed in 32 cases (32/100). Nuclear positive staining correlated with HER2/neu overexpression (P = 0.043) and was significantly associated with positive involvement of axillary lymph nodes (P = 0.013). No correlation was found between cytoplasmic pAkt rate and clinicopathological parameters, estrogen receptor, progesterone receptor or HER2/neu expression.

Conclusions:
pAkt expression can be evaluated in cytological material and may add valuable information to current prognostic models for breast cancer. pAkt overexpression appears to be linked with potentially aggressive tumor phenotype in invasive breast carcinoma.

Published: March 2015

Purpose. Worksite wellness, safety, and violence prevention programs have low penetration among small, independent businesses. This study examined barriers and strategies influencing small business participation in workplace violence prevention programs (WVPPs). Approach. A semistructured interview guide was used in 32 telephone interviews. Setting. The study took place at the University of North Carolina Injury Prevention Research Center. Participants. Participating were a purposive sample of 32 representatives of small business–serving organizations (e.g., business membership organizations, regulatory agencies, and economic development organizations) selected for their experience with small businesses. Intervention. This study was designed to inform improved dissemination of Crime Free Business (CFB), a WVPP for small, independent retail businesses. Methods. Thematic qualitative data analysis was used to identify key barriers and strategies for promoting programs and services to small businesses. Results. Three key factors that influence small business engagement emerged from the analysis: (1) small businesses' limited time and resources, (2) low salience of workplace violence, (3) influence of informal networks and source credibility. Identified strategies include designing low-cost and convenient programs, crafting effective messages, partnering with influential organizations and individuals, and conducting outreach through informal networks. Conclusion. Workplace violence prevention and public health practitioners may increase small business participation in programs by reducing time and resource demands, addressing small business concerns, enlisting support from influential individuals and groups, and emphasizing business benefits of participating in the program.
Small Convenience Stores and the Local Food Environment: An Analysis of Resident Shopping Behavior Using Multilevel Modeling
Authors: Ruff Ryan Richard , Akhund Ali , Adjoian Tamar 
Published: March 2015

Purpose. Local food environments can influence the diet and health of individuals through food availability, proximity to retail stores, pricing, and promotion. This study focused on how small convenience stores, known in New York City as bodegas, influence resident shopping behavior and the food environment. Design. Using a cross-sectional design, 171 bodegas and 2118 shoppers were sampled. Setting. Small convenience stores in New York City. Subjects. Any bodega shopper aged 18+ who purchased food or beverage from a participating store. Measures. Data collection consisted of a store assessment, a health and behavior survey given to exiting customers, and a bag check that recorded product information for all customer purchases. Analysis. Descriptive statistics were generated for bodega store characteristics, shopper demographics, and purchase behavior. Multilevel models were used to assess the influence of product availability, placement, and advertising on consumer purchases of sugar-sweetened beverages (SSBs), water, and fruits and vegetables. Results. Seventy-one percent of participants reported shopping at bodegas five or more times per week, and 35% reported purchasing all or most of their monthly food allotment at bodegas. Model results indicated that lower amounts of available fresh produce were significantly and independently associated with a higher likelihood of SSB purchases. A second, stratified multilevel model showed that the likelihood of purchasing an SSB increased with decreasing varieties of produce when produce was located at the front of the store. No significant effects were found for water placement and beverage advertising. Conclusions. Small convenience stores in New York City are an easily accessible source of foods and beverages. Bodegas may be suitable for interventions designed to improve food choice and diet.
Two distinct desynchronization processes caused by lesions in globally coupled neurons
Authors: Ferrari Fabiano A. S. , Viana Ricardo L. 
Published: March 2015

To accomplish a task, the brain works like a synchronized neuronal network where all the involved neurons work together. When a lesion spreads in the brain, depending on its evolution, it can reach a significant portion of relevant area. As a consequence, a phase transition might occur: the neurons desynchronize and cannot perform a certain task anymore. Lesions are responsible for either disrupting the neuronal connections or, in some cases, for killing the neuron. In this work, we will use a simplified model of neuronal network to show that these two types of lesions cause different types of desynchronization.Received: 20 November 2014, Accepted: 10 March 2015; Edited by: C.

Rituals in the resistance of squatting
This article examines the transformations in form and function of rituals in the squatting movement in Amsterdam. Upon roaring early years, rituals emerged around the search for houses to squat, the actual squatting and evictions. These rituals were recognized and used by squatters as well as other parties and they have contributed to the reduction of violence. Meanwhile, squatting in the Netherlands was prohibited and the question arises if, in this new situation, form and function of rituals have changed too. The findings shed some light on the broader link between rituals and resistance.
Narcissism, Self-esteem, Communication Apprehension, and Need for Affiliation: Difference between Social Networking Site Users and Non-users

Published: March 2015

Abstract
Nowadays, people are increasingly using social networking sites to initiate and maintain friendships, obtain social support and gather data. Personal traits could potentially drive people to join social networking sites as well as indulge in other related behaviors. This study aims to examine whether people with the need for affiliation, narcissism, self- esteem and communication apprehension are more likely to join social networking sites. Data for the current study were collected using convenience sampling; the sample consisted of undergraduate students studying at three private universities in Tehran, Iran. We used IBM SPSS 20 to run logistic regression statistics to test the research hypotheses developed for this study based on the responses from 284 respondents. The results of this study reveal that self-esteem, communication apprehension and the need for affiliation are significant predictors for social networking site usage while narcissism is not.
Parity and Non-Parity Determinants of Exchange Rates in Latin American Economies
Authors: Ho Catherine S. F. , Ariff M. 
Published: March 2015

AbstractThis paper reports how non-parity fundamental factors together with parity factors are correlated with exchange rate movements. Seven Latin American countries were included in this study using a selection criterion that for a pair of countries to be included, the pair must have more than 50 per cent of trade with the group chosen. The econometric methods applied are appropriate to this topic and include pooled time series regression and seemingly unrelated regression. The findings show that there is support for short and long-run effects on exchange rates from inflation and interest rates. We entered non-parity factors suggested in recent research reports as likely determinants of the exchange rates, and found four non-parity factors that are significantly correlated with exchange rates and these served as control variables in our test model. Our main result shows that both inflation and interest rates are jointly significant factors in most of the tests. The results appear to suggest that exchange rate research should include both nonparity and parity factors. Only then would the parity factor effects be identifiable as relevant to exchange rate formation.
Ionospheric plasma dynamics and instability caused by upward currents above thunderstorms
Authors: Kuo C. L. , Lee L. C. 
Published: March 2015

AbstractThunderstorms are electric generators, which drive currents upwardly into the ionosphere. In this paper, we examine the effects of thunderstorm upward current on the ionosphere. We use a thunderstorm model to calculate the three‐dimensional current flows in the atmosphere and to simulate the upward current above the thunderstorm with the tripole‐charge structure. The upward current flows into the ionosphere, while the associated electric field causes the plasma E × B motion. The caused plasma motion redistributes the plasma density, leading to ionospheric density variations. In the nighttime ionosphere, the E × B motion may also cause the formation of plasma bubbles.

AbstractThe spatial distributions of different ion species are useful indicators for plasma sheet dynamics. In this statistical study based on 7 years of Cluster observations, we establish the spatial distributions of oxygen ions and protons at energies from 274 to 955 keV, depending on geomagnetic and solar wind (SW) conditions. Compared with protons, the distribution of energetic oxygen has stronger dawn‐dusk asymmetry in response to changes in the geomagnetic activity. When the interplanetary magnetic field (IMF) is directed southward, the oxygen ions show significant acceleration in the tail plasma sheet. Changes in the SW dynamic pressure (Pdyn) affect the oxygen and proton intensities in the same way. The energetic protons show significant intensity increases at the near‐Earth duskside during disturbed geomagnetic conditions, enhanced SW Pdyn, and southward IMF, implying there location of effective inductive acceleration mechanisms and a strong duskward drift due to the increase of the magnetic field gradient in the near‐Earth tail. Higher losses of energetic ions are observed in the dayside plasma sheet under disturbed geomagnetic conditions and enhanced SW Pdyn. These observations are in agreement with theoretical models.
Seasonal differences in intraseasonal and interannual variability of Mediterranean Sea surface temperature
Authors: Zveryaev Igor I. 
Published: March 2015

AbstractSea surface temperature (SST) data from the NOAA OI SST data set for 1982–2011 are used to investigate intraseasonal and interannual variability of Mediterranean SST during winter and summer seasons. It is shown that during winter the intraseasonal SST fluctuations are larger than the interannual SST variations in the western Mediterranean (e.g., the Tyrrhenian Sea), but smaller in the central and eastern Mediterranean Sea. In summer, the intraseasonal SST fluctuations are larger in almost the entire Mediterranean basin. Also summertime intraseasonal SST fluctuations are larger (up to three times near the Gulf of Lions) than their wintertime counterparts in the entire Mediterranean basin. The interannual SST variations are larger during summer in the western and central Mediterranean Sea and during winter in its eastern part. The leading empirical orthogonal functions (EOFs) of the Mediterranean SST and of the intensities of its intraseasonal fluctuations are characterized by the differing spatial‐temporal structures both during winter and summer implying that their interannual variability is driven by different physical mechanisms. During winter, the EOF‐1 of SST is associated with the East Atlantic teleconnection, whereas EOF‐1 of the intensity of intraseasonal fluctuations is not linked significantly to regional atmospheric dynamics. The second EOFs of these variables are associated, respectively, with the East Atlantic/West Russia and the North Atlantic teleconnections. While during summer the atmospheric influence on Mediterranean SST is generally weaker, it is revealed that the EOF‐1 of the intensity of intraseasonal SST fluctuations is linked to the Polar teleconnection.
Inconsistency in Chinese solar radiation data caused by instrument replacement: Quantification based on pan evaporation observations
Authors: Yang Hanbo , Li Zhe , Li Mingliang , Yang Dawen 
Published: March 2015

AbstractSolar radiation determines our climate and hydrological cycle, and it has been widely measured by pyrometers at meteorological stations. In the early 1990s, a large‐scale instrument replacement occurred across China, leading to inconsistent solar radiation observations. Fortunately, China has consistent pan evaporation (Epan) observations from Chinese micropans (with a diameter of 20 cm) from the 1950s to 2001. This study parameterized the PenPan‐20 model for estimating Epan from these pans using a Bayesian approach. Furthermore, based on the PenPan‐20 model, a shift in the solar radiation data (~1.4 ± 0.5 MJ/(d m2) or 16 ± 7 W/m2) in the early 1990s was revealed; this change was likely due to the large‐scale retrofitting of new instruments and irregular calibration operations.
