Apatite with lamellae of sulfide and other phases in ultrahigh-pressure eclogites from Nové Dvory, Moldanubian Zone, Czech Republic
Authors: Faryad Shah Wali , Jedlicka Radim , Perraki Maria
Published: July 2018

Exsolution lamellae of baryte, Fe sulfides, Cu sulfides and Fe oxides were observed in apatite enclosed in garnet and omphacite and their intergranular spaces in ultrahigh-pressure eclogite in the Moldanubian Zone, Czech Republic. Micro-textural relations and compositional mapping of the apatite indicates a close relationship between the density of the exsolution lamellae and compositional domains that are rich in sulfur and iron. No relation between compositional domains and fluorine or chlorine content or any evidence of apatite metasomatisation was observed. On the basis of cathodoluminescence images, the compositional domains reflect sector zoning in apatite crystals by preferential uptake of elements due to differences in surface charge and morphology on the growth plane. It is concluded that the lamellae are products of exsolution in a closed system resulting from temperature decrease during metamorphism.

Published: July 2018

Purpose

Advanced dermatofibrosarcoma protuberans (DFSP) is an exceptionally uncommon disease with scarce literature, especially from developing countries. Molecular testing is unfortunately not available in India, and expert diagnosis by a sarcoma pathologist is available only in tertiary care centers.

Materials and Methods

We retrospectively analyzed consecutive patients with inoperable DFSP (on the basis of expert histopathology only) who presented to our sarcoma medical oncology clinic from January 2016 to July 2017.

Results

There were a total of seven patients, with median age of 35 years, predominantly males (85.7%). Fibrosarcomatous variant and metastatic disease were present in six (85.7%) patients. Partial response rates were 71.4%, and overall disease control was 85.7%. Median progression-free survival was 14 months.

Conclusion

DFSP diagnosis on the basis of expert histopathology in the absence of translocation can help out in targeted therapy–based treatment until translocation testing becomes available. The fibrosarcomatous variant has poor outcome, and further research is needed to help this group of patients.
Correlation Diagrams of Epimeric Stereoisograms for Stereoisomerism of Cyclopropane Derivatives
Authors: Fujita Shinsaku
Published: July 2018

Stereoisomerism of cyclopropanes is systematically discussed by means of stereoisograms and their correlation diagrams. A cyclopropane skeleton is governed by a main RS-stereoisomeric group constructed from its point group D3h, where the main RS-stereoisomeric group generates a set of main stereoisograms. An epimerization process at each of the carbon centers in the cyclopropane skeleton is characterized by an epimeric RS-stereoisomeric group, which generates a set of epimeric stereoisograms. The main RS-stereoisomeric group is combined with the epimeric RS-stereoisomeric groups, generating a stereoisomeric group for characterizing the cyclopropane skeleton. A set of epimeric stereoisograms at each RS-stereogenic center along with a set of main stereoisograms constructs a correlation diagram of stereoisograms. Such correlation diagrams are used to discuss local chirality and local RS-stereogenicity, where the RS-stereogenicity is correlated to the capability of giving RS-stereodescriptors.
The Effect of Public Pension Wealth on Saving and Expenditure
Authors: Lachowska Marta , Myck Michał
Published: July 2018

This paper examines the degree of substitution between public pension wealth and private saving by studying Poland’s 1999 pension reform. The analysis identifies the effect of pension wealth on private saving using cohort-by-time variation in pension wealth induced by the reform. The estimates, which are based on the 1997–2003 Polish Household Budget Surveys, show that 1 Polish zloty (PLN) less of pension wealth increases household saving by 0.3 PLN. Among highly educated households, pension wealth and private saving appear to be close substitutes. (JEL D14, E21, H55, I38)
Consumer Valuation of Fuel Costs and Tax Policy: Evidence from the European Car Market
Authors: Grigolon Laura , Reynaert Mathias , Verboven Frank
Published: July 2018

To what extent do car buyers undervalue future fuel costs, and what does this imply for tax policy? To address both questions, we show it is crucial to account for consumer mileage heterogeneity. We use product-level data for a panel of European countries and exploit fuel cost variation by engine. Despite a modest undervaluation of fuel costs, fuel taxes are more effective in reducing fuel usage than product taxes. They also perform better in terms of welfare, even when usage demand is held fixed. The reason is that fuel taxes better target high mileage consumers to purchase fuel efficient cars.

Published: July 2018

Remains of fossil plants, which form the famous «Petrified forest of Lesvos», have been found in many localities on the western part of Lesvos Island. The fossilized forest of Lesvos was developed during Late Oligocene to Lower - Middle Miocene, due to the intense volcanic activity in the area (Velitzelos and Zouros, 1997). The products of the volcanic activity had covered the vegetation of the area and the fossilization process took place due to favorable conditions. The fossilized plants in Lesvos are silicified remnants of a sub-tropical forest that existed on the northwest part of the island 20-15 million years ago. In the present study the results of the geophysical survey that has been applied to several locations of the petrified forest are presented. Electrical tomography, magnetic mapping and Ground Penetrating Radar methods of geophysical prospecting have been applied. The surrounding material, which is formed mainly by volcanic ash, contains also volcanic rocks in that size that it could be detected as petrified trunk. So, the effectiveness of the geophysical methods in such an environment has been tested in selected areas where petrified trunks were semi-uncovered. Lied trunks have been successfully detected by the electric tomography in several cases, since the resistivity of the fossilized material is much higher that the resistivity of the volcanic ash. The horizontal mapping of the total magnetic field in the same cases of lied trunks has been also successful since it was combined with the electric tomography and the anomaly were located in the same place and shape. Detection of petrified trunks looks to be uncertain in cases of standing trunks. That, because anomaly of the same pattern could be produced by an intrusion of a rock which the magnetic susceptibility is lower than this of the fossilized material. The same problem has been noticed also to the GPR (Ground Penetrating Radar) data. Several positions to be excavated have been proposed.

Published: July 2018

Milos island belongs to the Greek volcanic arc and is part of a small number of hot spots in the South Aegean Sea. It is an area that stands out for the diversity in volcanic formations and chemical composition of rocks. The island is characterized by the presence of a high enthalpy geothermal field and a non continuous microseismic activity, expressed both by tectonic earthquakes and swarm activity. During the period of our study (May-December 1999), this activity, which was recorded by a small, portable, seismological network has been very small and limited in the SE part of the island. From the chemical analyses performed, no significant alterations in the composition of the hydrothermal fluids was detected, except from slight changes in the content of K, Ca and Li and even smaller changes in Mg and Fe. This fact certainly implies a possible relation between microseismic activity and alterations in the content of various chemical elements, but it still needs further verification, which means that our research should be prolonged for a time period of at least two years

The area under studying is situated in the western part of Albania. A number of oilfields within the orogene have been found over the platform. There are analysed a lot of different cases of trapping in carbonate structures. Application of SeisWork2D is a powerful interpretative tool, that gives us new insight into the subsurface. Subtle details that would be hidden on paper section are revealed on the screen, thanks to color, high-resolution graphics and a wide variety of display options. Gathered and analysed data consist of exploration and development wells, seismic lines, logs, well testing, geochemical and petrophysical analyses. Some types of the traps are demonstrated practically and are prescribed in conformity with incontestable the facts data. The paper intent to explain main geological factors that influenced in trap formation in carbonate reservoirs and the characteristics of seismic facies on carbonate. The experience shows that it is difficult to explore the traps in a complicated geological framework, where a complex of the geological phenomena's are interfered

The study area is located in the sourthen part of Albania. The paper presents the geological – geophysical interpretation of the Selenica - Amantia area. It represents the central part of the Jonian Unit, from the tectonic point of view. This area is characterized by an intensive tectonic activity and by presence of some source rocks in Mesosoic carbonate section. It represents one of the most perspective zone and exploration opportunities. In the paper is treated meanly seismic velosity model as a very important tool for interpretation of geological framework of the area. During the work we had present many geological data as deep wells, surface geology, seismic and gravimetry data. Reprocessing of the seismic lines with updata programs helped us to improve interpretation and identifiding the most important prospects.
Possible triggering of strong earthquakes in a seismic sequence due to Coulomb stress changes generated by the occurrence of previous strong shocks
Authors: PAPADIMITRIOU E. E. , KARAKOSTAS V. G. , BABA A. B.
Published: July 2018

Coulomb stress changes (ACFF)were calculated assuming that earthquakes can be modelled as static dislocations in an elastic half-space, and taking into account the coseismic slip in strong earthquakes. The stress change calculations were performed for strike, dip, and rake appropriate to the strong events considered. We evaluate if these chosen earthquakes brought a given strong subsequent event closer to, or farther from, failure. It was found that each of the subsequent strong events occurred in regions of increased calculated Coulomb stress before their occurrence. Moreover, the majority of smaller aftershocks also were located in areas of positive ACFF. This indicates the probable triggering of the latter events, the foci of which are situated at nearby faults or fault segments.
The Konitsa, Epirus-NW Greece, July 26 (Ms=5.4) and August 5, 1996, (Ms=5.7) earthquakes sequence
Authors: PAPANASTASSIOU D.
Published: July 2018

On August 5, 1996, at 22:46 GMT (August 6, 01:46 local time), a strong shallow earthquake of Ms=5.7 occurred at the area of Konitsa, Epirus-northwestern Greece. The earthquake caused significant damage in the city of Konitsa as well as the neighbouring villages. In the same area on July 26, at 18:55 GMT (21:55 local time), another strong earthquake of Ms=5.4 had occurred, mainly causing damage at the lower part of Konitsa. In this study, data from seismological stations located in the broader area of NE Greece and neighbouring countries were used in order to study the spatial and temporal characteristics of this earthquake sequence. Focal mechanisms of the stronger shocks were also plotted. All the observations are combined, in order to obtain a better understanding of the regional tectonics and its seismic activity.
A method for estimating the origin time of an ensuing mainshock by observations of preshock crustal seismic deformation
Authors: PAPAZACHOS B. C. , KARAKAISIS G. F. , PAPAZACHOS C. B. , SCORDILIS E. M. , SAVVAIDIS A. S.
Published: July 2018

Observations on accelerating crustal deformation due to the generation of intermediate magnitude preshocks in the Aegean area are used to propose a method for prediction of the origin time of an ensuing mainshock. The method is based on a precursory seismic excitation that occurs in the preshock region at a time correlated to the origin time of the oncoming mainshock. The uncertainty in this prediction is of the order of ± 1.5 years with relatively high confidence ('90%).
Spatial distribution of the seismic hazard parameters in the seismogenic sources of Japan

Published: July 2018

The seismicity parameters in the seismogenic zones of Japan are estimated by the application of two different approaches. These are the maximum likelihood method as well as the Bayesian estimator is invoked in order to check the validity of the results. Both methods allow us to estimate the maximum regional (possible) earthquake M , the well known value β (b=ßloge) which is the slope of the magnitude-frequency relation and the mean activity rate /[ of the seismic events. The present study is focused in the first two parameters searching for any pattern on their geographical distribution through the sources of Japan. Two are the main assumptions adopted for both methods: 1) the seismic events are of Poissonian character and 2) the magnitude-frequency law is governed by Gutenberg-Richter type. The methods allow to account the influence of uncertainties of the earthquakes magnitude. Taking into account these properties we found that the values of M are different and bigger than the observed M^*x . The estimated b-values show very low values in the seismogenic sources 2 and 7. In comparison with other measurements from other authors these two sources suggested to be areas with very high probability for an large earthquake occurrence
Differences are Different: Examining the Effects of Communication Media on the Impacts of Racial and Gender Diversity in Decision-Making Teams
Authors: Robert Lionel P. , Dennis Alan R. , Ahuja Manju K.
Published: July 2018

Diversity can have positive and negative effects on team decision making. Text communication has been put forth as one solution to addressing this duality of team diversity. Unfortunately, the empirical results have been far from conclusive. We believe that resolving such inconsistencies is crucial to developing a more complete understanding of the use of communication technologies. To accomplish this, we developed a research model based on media synchronicity theory. We empirically tested this model by conducting a laboratory experiment with 46 teams, consisting primarily of men and women self-identified as Caucasians and Asians, performing a decision-making task. The results show that the type of diversity matters. Text communication improved knowledge sharing (i.e., conveyance) and knowledge integration (i.e., convergence) in racially diverse teams but impaired both in gender diverse teams. Knowledge integration was more important to decision quality when racial and gender diverse teams used text communication (but the importance of knowledge sharing was not affected by the communication medium).

On Incomplete Learning and Certainty-Equivalence Control
Authors: Keskin N. Bora , Zeevi Assaf
Published: July 2018

We consider a dynamic learning problem where a decision maker sequentially selects a control and observes a response variable that depends on chosen control and an unknown sensitivity parameter. After every observation, the decision maker updates his or her estimate of the unknown parameter and uses a certainty-equivalence decision rule to determine subsequent controls based on this estimate. We show that under this certainty-equivalence learning policy the parameter estimates converge with positive probability to an uninformative fixed point that can differ from the true value of the unknown parameter; a phenomenon that will be referred to as incomplete learning. In stark contrast, it will be shown that this certainty-equivalence policy may avoid incomplete learning if the parameter value of interest “drifts away” from the uninformative fixed point at a critical rate. Finally, we prove that one can adaptively limit the learning memory to improve the accuracy of the certainty-equivalence policy in both static (estimation), as well as slowly varying (tracking) environments, without relying on forced exploration.
Oxygen therapy in adult patients. Part 1: understanding the relevant physiology and pathophysiology
Authors: Rolfe Sandy , Paul Fiona
Published: July 2018

Oxygen therapy is a treatment commonly used for adult patients in clinical and community settings. It is therefore important that nurses and other members of the healthcare team caring for patients requiring oxygen therapy have knowledge of the relevant physiology and pathophysiology, along with the safe and effective use of oxygen devices, patient monitoring and oxygen prescribing. This two-part article aims to explore and discuss these aspects in relation to current evidence and best practice recommendations that members of the healthcare team can apply when caring for such patients in a range of settings. Part one discusses the physiology of respiration and the importance of adequate oxygenation within the human body; it covers other relevant physiology and pathophysiology, along with the reasons why adult patients may require oxygen therapy. The authors describe the physiology and pathophysiology associated with the uptake and delivery of oxygen from the lungs to the body cells. Oxygen devices will be discussed in the second article, along with the importance of patient assessment, care, management, safety and patient monitoring.
Confidence and deeper learning: simulated practice within pre-registration nurse education
Authors: Morrell-Scott Nicola
Published: July 2018

A qualitative phenomenological research study sought to determine the perceptions of final-year nursing students about the value of simulation during their nurse education. The study sample consisted of 18 final-year students, and semi-structured interviews were undertaken. Data analysis using interpretative phenomenological analysis was carried out. The findings suggest that nursing students perceive simulation as a useful educational tool, which can increase their confidence and encourage deeper learning. The relevance of this research also relates to the potential for more simulated time within the new educational standards.

Emergency inserted peripheral intravenous catheters: a quality improvement project
Authors: Ruegg Leanne , Faucett Mark , Choong Keat
Published: July 2018

Vascular access devices are common and necessary in healthcare provision but their use poses a significant risk of acquiring an infection. Ambulance/emergency inserted peripheral intravenous catheters (PIVCs) potentially have higher risks of catheter-related bloodstream infection (CRBSI) because of the inability to maintain asepsis during the insertion procedure. Local guidelines (Queensland, Australia) recommend the removal or replacement of PIVCs inserted in these situations within 24 hours. Routine clinical audits performed within the authors' health service demonstrated a delay in removing ambulance/emergency inserted PIVCs beyond acceptable dwell times. Ambulance/emergency inserted PIVCs were not being recognised as requiring removal by ward staff. A quality improvement project involving key stakeholder engagement, the roll out of a sticker to readily identify ambulance/emergency inserted PIVCs and education of ward staff was introduced to enable identification of this high-risk group. Post-implementation audits demonstrated a significant reduction in numbers of ambulance/emergency PIVCs remaining in situ for longer than 24 hours.

Nudge and evidence based policy: fertile ground
Authors: Einfeld Colette
Published: July 2018

Nudge is an approach to public policy that changes the decision-making environment to encourage citizens to make a particular choice. The approach has been eagerly adopted by administrations around the world, with some governments establishing dedicated nudge units to advance their use. One reason proposed for nudge’s popularity is that it supports evidence-based policy. Nudging seems to be firmly positioned in evidence-based policy rhetoric, and encourages the use of Randomised Control Trials to determine the effectiveness of a policy. There is little empirical understanding on whether nudge’s association with this rhetoric has contributed to its increasingly widespread application. This research explores how nudge is understood in relation to the evidence-based movement, from the perspective of those designing, developing and implementing nudge policies. In-depth, qualitative interviews were undertaken with policymakers in Australia. This paper finds policymakers perceive an interconnected relationship between nudging and evidence-based policy, with each providing fertile ground for the growth of the other. Consequences for scholarship and practice are discussed including implications for what constitutes legitimate evidence in the public service.

Published: July 2018

The efficacy of different chemical additives like acetic acid, ammonium molybdate, diethylene triamine pentaacetic acid (DTPA), mannitol, methanol, per acetic acid (PAA), sodium hypochlorite (NaOCl) and sulfamic acid as carbohydrate protector during ozone bleaching of wheat straw pulp was studied. DTPA was found the most effective additive for ozone bleaching followed by the methanol. Using DTPA during ozone treatment improved the delignification efficiency by 13.8 %, bleaching efficiency by 19.8 %, selectivity of ozone by 124 % and reduced the chain scission number of glycosidic linkages in cellulose by 55.3 % compared to that of control. Ozone treatment along with DTPA reduced the Fe, Cu and Mn content in the pulp by 52 %, 27 % and 70 %, respectively. Use of methanol improved the delignification efficiency by 9.0 %, bleaching efficiency by 12.2 %, selectivity by 32.4 % and reduced the chain scission number by 22.2 % compared to that of control. The NaOCl was found to be the most effective for improving the delignification efficiency followed by PAA, they improved the delignification efficiency by 29.3 % and 27.3 %, respectively. The PAA improved the bleaching efficiency to a maximum of 39.9 % followed by 30.2 % with NaOCl.

Published: July 2018

Granulosa cell tumor is a type of neoplasm, which represents 2-5% of all ovarian cancers. About 5% of these tumors are juvenile- type and usually occur to girls before puberty and to women younger than thirty years of age. There are signs premature puberty or premature emergence of secondary sexual characteristics with irregular vaginal bleeding that occur to these kind of patients. To the rare cases, like this, the occurrence of granulosa cell tumors can cause the appearance of hyperandrogenism with high levels of plasma testosterone, leading to virilization which happened to this female patient. We will present the female patient who was 35 years old and which was originally hospitalized to the Clinic for Haematology Clinical Center Kragujevac, because of extreme fatigue accompanied by dizziness. During diagnostics the patient underwent to the complete gynecological examination. After gynecological examinations and necessary diagnostic procedures, it was decided continuing the treatment at the Clinic of Gynecology and Obstetrics Clinical Center Kragujevac, where she underwent a total abdominal hysterectomy with bilateral salpingo- oophorectomy for suspected uterine neoplasm. Histopathological analysis of the obtained material confirmed the presence of follicular cysts of both ovaries and juvenile type granulosa cell tumor on the right ovary; the uterus was enlarged with multiple fibroid tumors. Granulosa cell tumor should be suspected in the cases of girls and young females if there is present an ovarian cyst paired with signs of preterm puberty or hyperestrogenism. In this case, the presence of granulosa cell tumor was masked by signs of hyperandrogenism, which is not so typical, as well as the presence of uterine fibroids who have actually been the main cause for surgical treatment.

Published: July 2018

Potentilla reptans is a little studied plant of the genus Potentilla, the family Rosaceae. The aim of this study is to determine antimicrobial effects of aqueous extracts of P. reptans aerial part and rhizome against standardized bacterial strains.

The antimicrobial activity of aqueous extracts of P. reptans aerial part and rhizome was tested against one fungus, Candida albicans, and two standard bacterial strains, Staphylococcus aureus and Escherichia coli, using an agar diffusion method.

Both examined extracts showed a significant antimicrobial activity against Escherichia coli and Staphylococcus aureus at the concentrations of 10 to 150 mg/ml. The rhizome extract showed stronger antimicrobial effect against the tested strains of bacteria than the aerial part extract.

The obtained results represent preliminary results of antimicrobial activity of this plant and suggest that in future, the studies should examine antimicrobial activity against other bacterial strains and minimum inhibitory concentration.
Use of Constant Energy Source in SASW Test and Its Influence on Seismic Response Analysis
Authors: Chakraborty Sayantan , Bheemasetti Tejo V. , Puppala Anand J. , Verreault Louie
Published: July 2018

The quality and acceptability of the results of the spectral analysis of surface waves (SASW) field test are dependent upon the coherence function, in conjunction with the transfer function. The coherence value is a measure of the quality of the test, and the transfer function denotes the phase lag between signals that are received by the geophones. This article presents a methodology for obtaining high-quality field test data, using a source capable of producing constant impact energy for several repeated impact strikes in an SASW test. Both laboratory and field investigations were performed to assess the effectiveness of the constant impact energy source at improving the coherence value. Tests were conducted on the surface of the soil compacted in a metal box and on the crest of an earthen dam using (a) handheld hammers, resulting in variable impact energy and (b) a drop hammer, dropped from a predetermined fixed height, resulting in constant impact energy. The variation in the shear wave velocity (Vs) profile obtained using the two testing methodologies and its impact on the seismic response analysis of an earthen embankment structure were studied. The SASW tests performed in the laboratory using constant impact energy were more efficient and repeatable than those performed using varying impact energy, and the results showed increased coherence values over a wide range of frequencies. A similar improvement in coherence data was observed in the field studies, and the Vs profiles were found to be significantly different for tests conducted using both methodologies. It was observed that the peak and spectral accelerations at the crest of embankments are significantly different when embankments with different Vs profiles are subjected to seismic excitation. This study emphasizes the importance of performing the SASW test, using a constant impact energy source to obtain a reliable estimate of Vs profiles of subsurface layers.

Pesquisas relacionas aos solos em ambientes de veredas vêm ganhando mais espaço, visto que os aspectos biológicos, como tipo de vegetação associada, sempre tiveram maior ênfase, em relação aos atributos do solo. Este estudo buscou analisar alguns atributos morfológicos, químicos e físicos em um perfil de gleissolo situado em uma vereda do município de São Desidério (oeste da Bahia) que contribui diretamente para as nascentes do rio Grande, importante afluente do Rio São Francisco. Para tanto, foi aberta uma trincheira, e o perfil de solo foi descrito morfologicamente e amostras foram coletadas para realização de análises granulométrica, de densidade de partículas, do teor de matéria orgânica e pH. Verificou-se a predominância de areia em todo o perfil. Mas, a distribuição das areias não é homogênea, com aumento da areia fina no horizonte intermediário. O teor de matéria orgânica na superfície é bem elevado, chegando a 8,35 % no horizonte A e o pH é inferior 5 em todo o perfil. Os resultados apontam indícios que o material no entorno da vereda pode ter sido trazido por fluxos hídricos. Este estudo tem um caráter de investigação preliminar, uma vez que se faz necessária à coleta e análise de um número maior de amostras de solo, para que se tenha uma maior representatividade sobre a dinâmica da vereda.ABSTRACT:Researches about the soils in vereda’s environments have been highlighted, once the biological aspects, like the kind of vegetation associated with it, has always been emphasized related to the soil attributes. This study aimed to analyze some physical, chemical and morphological attributes in a gleysol profile in São Desidério City (western Bahia) that directly contributes for the sources of the Grande River, an important affluent of the São Francisco River. For that, a trench was opened, the soil profile was morphologically described, and samples were collected for analysis of: granulometry, particles density, organic matter content and pH. It was verified the predominance of sand all over the profile. However, the sands distribution is not homogenous, increasing the fine sand on the intermediate horizon. The organic matter content on the surface is very high reaching up to 8.35% on the horizon A, and the pH is less than 5 throughout the whole profile. The results show that the materials around the vereda may have been brought by flows of water. This study has a character of preliminary investigation, once it is necessary to collect and analyze a higher number of soil samples, in order to get more representability about the vereda dynamics.Keywords: Permeability; Hydromorphic Soils; Textural Discontinuity

Locais propensos às atividades náuticas requerem um arranjo de fatores ambientais, culturais, econômicos e políticos para evidenciar, nos dias de hoje, a forte relação simbólica e valorativa nos entornos urbanos – e periurbanos - em que estão inseridos os portos náuticos. Conclui-se que no uso náutico do território passa a predominar mais o caráter corporativo e organizacional do que banal e orgânico, como em sua gênese no Brasil.ABSTRACT:The territorial approach of nautical, from a perspective of the social instances of space, consists of a proposal of analysis that integrates different scales and periods. Understood as a technical system, this object makes it possible to understand local, regional and global relations. Ports for this purpose are fundamental technical objects in nautical research. From its earliest expressions on the Brazilian coast, from popular use to the current characteristics, selective use changes are observed. Starting from the sporting function for the valorization of real estate and tourism, these objects acquire new characteristics within what is understood by use of the territory. Places with a propensity for nautical activities require an arrangement of environmental, cultural, economic and political factors to highlight the symbolic and value relationship in the urban and periurban environments in which the nautical ports are inserted. It is concluded that the nautical use of the territory happens to predominate more to corporative and organizational than banal and organic, as in its genesis in Brazil.Keywords: Technical system; Use of the territory; Nautical ports.
Geostrateški i sigurnosni aspekti potencijalnih utjecaja suvremenih migrantskih kretanja na Dalmaciju
Authors: Botić Jurica , Boban Marija
Published: July 2018

Europski geografski i politički prostor 2015. godine suočio se s kulminacijom jedne od najvećih migrantskih kriza u svojoj povijesti koja je posebno pogodila politički ranjivu Jugoistočnu Europu kao tradicionalno područje migrantskih kretanja. Ove tvrdnje dobivaju dodatno na važnosti uzimajući u obzir činjenicu da je Jugoistočna Europa, kao tradicionalno sjecište geopolitičkih silnica, danas dodatno izložena sigurnosnim izazovima, što ujedno pojačava i važnost njezine geostrateške pozicije. Pogođena migrantskom krizom na sjeveru i istoku, a uvažavajući turizam kao jednu od svojih temeljnih gospodarskih djelatnosti, Republika Hrvatska, iako hrvatske turističke destinacije poput Istre i Dalmacije nisu izravno izložene utjecajima migrantske krize, posebnu pozornost mora posvetiti zadržavaju imidža sigurne turističke destinacije. Stoga autori raspravljaju o geostrateškim i sigurnosnim aspektima te vjerojatnostima izloženosti Dalmacije utjecajima recentne migrantske krize. Naime, autori u članku potvrđuju da fizičko-geografska obilježja i političko-teritorijalna fragmentacija neposrednog susjedstva Dalmaciju ne čine atraktivnim odabirom za migrantska kretanja. Autori također zaključuju da potencijalno osnažena utjecajima migrantskih kretanja, politička nestabilnost susjedstva s visokim konfliktnim potencijalom na etno-religijskoj osnovi, može izazvati nove sigurnosne izazove u Jugoistočnoj Europi, a posredno i u Dalmaciji.

Background

Cutaneous lichen amyloidosis (CLA) has been reported in some multiple endocrine neoplasia type 2A (MEN 2A) families affected by specific germlineRETmutations C634F/G/R/W/Y or V804M, as a characteristic of the clinical manifestation in ‘MEN 2A with CLA’, one of four variants of MEN 2A, which was strictly located in the scapular region of the upper back.

Patient Findings

This study reports a large south-eastern Chinese pedigree with 17 individuals carrying the MEN 2A-harboring germline C611Y (c.1832G>A)RETmutation by Sanger sequencing. One individual presented MEN 2A-related clinical features, including typical CLA in the interscapular region; another individual exhibited neurological pruritus and scratching in the upper back but lacked CLA skin lesions. Both subjects presented with CLA or pruritic symptoms several years before the onset of medullary thyroid carcinoma (MTC) and/or pheochromocytoma. The remaining 15RETmutation carriers did not exhibit CLA; of these, one presented with MTC and pheochromocytoma, nine with MTC only, two with elevated serum calcitonin and three younger subjects with normal serum calcitonin levels. This family’s clinical data revealed a later diagnosis of MTC (mean age, 45.9 (range: 23–73) years), a lower penetrance of pheochromocytoma (2/17, 11.8%) and CLA (1/17, 5.9%). However, no hyperparathyroidism and Hirschsprung disease were reported in this family.

Summary and Conclusions

This is the first description of a family with MEN 2A-related CLA due to a germlineRETC611Y mutation, which might exhibit a novel and diversified genotype–phenotype spectrum in MEN 2A.

Yolanda Oreamuno y el panorama artístico costarricense en Repertorio Americano
Authors: Solano Moraga Sigrid
Published: July 2018

Repertorio americano representó una apertura al diálogo con intelectuales sobre perspectivas artísticas nacionales e internacionales. Entre ellos se contó con la participación de Yolanda Oreamuno, quien, a partir de un conjunto de textos literarios, evaluó el carácter del costarricense hacia el arte, expuso la carencia de crítica hacia los artistas y sus creaciones, y criticó el costumbrismo en las letras. Esta investigación tiene por objetivo estudiar el panorama artístico descrito en los ensayos y narrativa lírica de la autora, publicados en la revista dirigida por Joaquín García Monge, entre ellos: “La vuelta a los lugares comunes” (1939), “El último Max Jiménez ante la indiferencia nacional” (1939), “Protesta contra el folclore” (1943) y “Max Jiménez y los que están” (1947). Los anteriores escritos exponen el carácter transgresor de Oreamuno, su producción crítica y dialógica; además, la imponen como pensadora ruptora de roles sociales.
Retrato de la homosexualidad y la homofobia en la literatura costarricense
Authors: Miranda Joselyn
Published: July 2018

La literatura, como otras artes, es una expresión de la humanidad, de su día a día, de sus miedos e ilusiones, de su historia pasada, presente y futura. Ella permite vestir los zapatos de otros y ver de cerca diferentes vidas y puntos de vista. En el presente ensayo se muestra un análisis/opinión sobre extractos de literatura erótica, en especial homosexual, escritos por autores costarricenses y recopilados en la antología La gruta y el arcoíris: antología de narrativa gay/lésbica costarricense de Alexánder Obando, quienes han expuesto en sus textos, personajes dentro de una sociedad que en la actualidad sigue con una mentalidad un tanto cerrada, conservadora y muchas veces mojigata e hipócrita.

Apuntes para una reflexión: nuevas tendencias de la literatura para niños y jóvenes
Authors: Pérez Yglesias María
Published: July 2018

El título (el nombre) de un artículo, de un discurso, de una película, de una pintura... es siempre, de alguna manera, la marca de un espacio y un límite. Informa, sugiere, invoca, persuade sobre su consumo, condiciona una lectura (escucha, visión...) pero, sobre todo, crea en el perceptor –también participante– unas expectativas marcadas por su propio saber sobre la temática, su perspectiva filosófica, su posición ideológico-social.

Nueva poesía de argentina
Authors: Acosta Domingo
Published: July 2018

Como parte de un contexto con inquietudes latentes, pero a la vez fruto de una discontinuidad en lo social y político, lo que en verdad podríamos llamar Nueva Producción Poética de Argentina, lejos de resignar su actividad a un gesto de indulgencia –sin aceptar, tampoco, un cultivo del “testimonio por el testimonio”-, demuestra cómo dentro de una misma poética pueden darse marcadas diferencias. Si bien no estamos hablando de homogeneidades, uniformidades, no puede negarse que hay un camino en común en estas producciones poéticas.

En este artículo se analiza América Latina como una región donde el concepto de “sociedad posible” ha sido utilizado por mucho tiempo.

Ser o no ser católico en América Latina: el dilema vigente
Authors: Quesada Chaves Marco Antonio
Published: July 2018

La situación de lo religioso en América Latina mostrada por dos importantes estudios como lo son el del Pew Research Center y el Latinobarómetro; ambos realizados en 2014, denotan una serie de transformaciones importantes en la manera como es entendido, asumido y vivido lo religioso por la mayoría de latinoamericanos(as). Se atiende a un decrecimiento en el número de personas que se identifican como católicas, a su vez que hay un creciente número de protestantes y un tercer grupo que no posee filiación religiosa alguna, pero que no deja de ser religioso. A partir de una perspectiva histórico-teológica, el presente artículo discute dos fenómenos que se encuentran en la presente situación: el de la secularización desde la realidad latinoamericana y el de los llamados “católicos culturales”, un fenómeno complejo, paradójico como también desafiante.

La educación del visitante a los museos tiene un componente más allá de lo puramente didáctico, el cual se relaciona con el conocimiento del arte como lenguaje y de la historia del arte. Así mismo, es importante establecer las fronteras con otros géneros que utilizan la imagen como el cine y el documental. Este es el propósito del artículo.
