Presencia 2.0 de las pymes gallegas: niveles de participación y engagement con los usuarios
Authors: Sixto García José , Aguado Domínguez Nicolás , Riveiro Castro Reyes
Published: January 2017

Partiendo de la necesidad de las organizaciones de adaptarse a los entornos 2.0 como una exigencia de los mercados actuales, esta investigación cuantifica y analiza la presencia y la participación de las pymes gallegas en los medios sociales. Metodología. Para ello hemos analizado desde los puntos de vista cuantitativo y cualitativo la cantidad y la calidad de los registros atendiendo a tipos de presencias, frecuencias de actualización, niveles de interacción y estrategias de comunicación implementadas para la consecución de un diálogo social entre público-organización. Resultados y conclusiones. Las conclusiones apuntan a la supremacía de Facebook como red de uso mayoritario, aunque apenas la mitad de las pymes emplean las redes sociales como canal de comunicación, sino que reflejan más una presencia testimonial y de posicionamiento SEO que un espacio dialógico, por lo que los niveles de engagement son pobres y reducidos a casos puntuales, nunca una tendencia generalizada.
The exploitation of animal resources in Șoimuș-La Avicola (Ferma 2) settlement (Romania)
Authors: Mărgărit Monica , Ștefan Cristian Eduard , Dumitrașcu Valentin
Published: January 2017

The aim of this paper is to present an interesting archaeological assemblage discovered during archaeological research at the settlement of Șoimuș-La Avicola (Ferma 2) (Romania). So far, this is the only example of a Turdaș culture osseous assemblage published. It is numerically representative, with 901 pieces, of which 796 are bone, 94 antler, 8 tooth and 3 valve. Among the bone pieces, a high standardisation in the selection of blanks is noticeable, with Bos taurus ribs being prevalent. At the same time, the techniques and procedures vary only a little within the groups, which allows for the identification of typological series. The recovery of all the products and sub-products resulting from the operational sequences of raw material transformation and the analysis of the wear and technological traces led us to try to reconstruct a behavioural model of the ways raw material was acquired, processing techniques and activities developed with them, or in other words to outline the economic and cultural features of the Șoimuș-La Avicola (Ferma 2) community.
Ceramics among Eurasian hunter-gatherers: 32 000 years of ceramic technology use and the perception of containment
Authors: Budja Mihael
Published: January 2017

We present two parallel and 32 000 years long trajectories of episodic ceramic technology use in Eurasian pre-Neolithic hunter-gatherer societies. In eastern, Asian trajectory the pottery was produced from the beginning. Ceramic figurines mark the western, European trajectory. The western predates the eastern for about eleven millennia. While ceramic cones and figurines first appeared in Central Europe at c. 31 000 cal BC the earliest vessels in eastern Asia was dated at c. 20 000 cal BC. We discuss women’s agency, perception of containment, ‘cross-craft interactions’, and evolution of private property that that may influenced the inventions of ceramic (pyro)technology.
A small-scale cult centre in Southeast Turkey: Harbetsuvan Tepesi
Authors: Çelik Bahattin
Published: January 2017

The present paper aims to assess the finds from Harbetsuvan Tepesi, which we consider a small-scale satellite settlement located some 7km southwest of Karahan Tepe. The paper also endeavours to show analogous characteristics of Harbetsuvan Tepesi by comparing the site with PPN settlements in adjacent regions. The remains of a round-plan building, a recent discovery observed on the surface in Harbetsuvan Tepesi, which features T-shaped pillars, is particularly notable. The remains of this building, which has characteristics analogous to ‘Enclosure F’ at Göbekli Tepe, is extremely important, as it demonstrates that round-plan buildings were still in use during the early PPNB period.

Published: January 2017

In the first half of the 1980s, lithic materials from the prehistoric settlement of Ovčarovo-Gorata in northern Bulgaria were studied by Vietnamese archaeologist Nguyen Van Binh. At that time, he was a doctoral student in the Department of Prehistory of the National Archaeological Institute and Museum Bulgarian Academy of Sciences. In 1985, Nguyen Van Binh completed his doctoral thesis “Prehistoric flint artifact assemblages from the Late Pleistocene and Early Holocene on the basis of materials from North East Bulgaria”, which presents the results of lithic assemblages processed from the site.
‘Neolithisation’ in the NE Sea of Azov region: one step forward, two steps back?
Authors: Gorelik Alexander Felix , Tsybrij Andrej , Tsybrij Viktor
Published: January 2017

In this paper we present the migratory nature of an initial Neolithisation in the Sea of Azov area on the basis of an analysis of comparatively new and a revision of old materials from the Early Neolithic period. As the ‘ancestral land’ of elements of the Neolithic package, the region of Zagros Mountains is considered, from where communication with Lower Don across the Caucasian coast of the Black Sea and Sea of Azov or by sea took place in the PPNB period. It seems that infiltration did not lead to a strong Neolithic transformation as seen in other regions ‘secondary Neolithisation’, e.g., in Europe. The choice of a place for repeated occupation, the organisation of the living area, way of life, subsistence, and perception of the world, for a long time remained typical of the foragers of river valleys, lake, and coastal areas of Europe. This pattern probably continued until the large-scale human movements of the Copper Age.
Initial stages of two Neolithisation models in the Lower Volga basin
Authors: Vybornov Alexander
Published: January 2017

In this paper, two groups of ancient sites located in the Lower Volga River basin are analysed. The first group is linked to the emergence of the oldest pottery in this region, which is one of the most ancient in Europe. The presence of this feature of the ‘Neolithic package’ can be dated to the middle of the 7th millenium BC. A production economy is a particular feature of the second group of sites, which can be dated to the end of the 6th millenium BC. This is one of the earliest pieces of evidence of the existence of domesticated species in Eastern Europe. These two groups of sites show the initial stages of two Neolithisation models in the Lower Volga basin.

Published: January 2017

Abstract. Stress accompanying animal production is both an indicator of welfare and a factor that affects economic parameters. Dynamic development of alternative poultry production systems such as outdoor, free range or ecological, strives to achieve best-quality products and to improve the living conditions of birds. Apart from the type and intensity of the external stimuli, the response to stress is determined genetically. Poultry rearing in the aforementioned systems requires selecting the appropriate genotype of birds, often including crosses of fast-growing and slow-growing lines. The objective of this study was to demonstrate differences in the physiological response to stress of fast-growing (FG) and slow-growing (SG) turkeys and their crosses: SF (SG  ×  FG) and FS (FG  ×  SG), based on hematological and biochemical blood analyses. Blood was sampled from 30 turkey hens from each of four genotypes, aged 14 weeks, subjected to standard pre-slaughter handling procedures. Compared to FG and FS turkeys, the SG and SF birds had a high total protein concentration, a higher heterophil (H) ∕ lymphocyte (L) ratio and a higher concentration of cortisol. In turn, the FG turkeys had the highest activity of enzymes: alanine transaminase, aspartate transaminase, lactate dehydrogenase, creatine kinase. Conversely, the FS turkeys had the highest concentrations of total cholesterol and low-density lipoprotein (LDLC) and the lowest concentration of cortisol. Significant positive effects of crossing were reported for total protein, cholinesterase and cortisol. Effects of crossbreeding on the percentage of H, concentrations of total cholesterol, and LDLC and activity of aspartate transaminase in blood of the crosses were significant but negative and more dependent on the sire line. Except for albumins, whose concentration in blood of crosses was higher compared to birds of pure lines, there were no advantages of heterosis. Negative heterosis was estimated for creatinine, the enzymes alanine transaminase and lactate dehydrogenase, and for cortisol. The most similar regarding creatinine, bilirubin, albumins, total protein, H, L and H ∕ L were the FS and SF groups. The greatest differences were in the following parameters: triglycerides, total cholesterol, high-density lipoprotein (HDLC), LDLC, glucose and lactate, which occurred between the pure lines of turkeys. Study results demonstrate various responses to stress in the analyzed groups of turkeys, with the level of stress measured with hematological and biological blood markers being mostly determined by additive genetic variation, and to a lesser extent by the maternal and sire effects.
Particle Size Dependence of Biogenic Secondary Organic Aerosol Molecular Composition
Authors: Tu Peijun , Johnston Murray V.
Published: January 2017

Abstract. Formation of secondary organic aerosol (SOA) is initiated by the oxidation of volatile organic compounds (VOCs) in the gas phase. Mass transfer to the particle phase is thought to occur primarily by a combination of condensation of non-volatile products and partitioning of semi-volatile products, though particle phase chemistry may also play a role if it transforms semi-volatile reactants into non-volatile products. In principle, changes in particle composition as a function of particle size allow the relative contributions of e.g. condensation (a surface-limited process) and particle phase reaction (a volume-limited process) to be distinguished. In this work, SOA was produced by β-pinene ozonolysis in a flow tube reactor. Aerosol exiting the reactor was size-selected with a differential mobility analyser, and individual particle sizes between 35 and 110 nm in diameter were characterized by on- and off- line mass spectrometry. Both the average oxygen-to-carbon (O / C) ratio and carbon oxidation state (OSc) were found to decrease with increasing particle size, while the relative signal intensity of oligomers increased with increasing particle size. These results are consistent with oligomer formation in the particle phase i.e. accretion reactions, which become more favoured as the surface-to-volume ratio of the particle decreases. Analysis of a series of polydisperse SOA samples showed similar dependencies: as the mass loading increased (and average surface-to-volume ratio decreased), the average O / C ratio and OSc decreased while the relative intensity of oligomer ions increased. The results illustrate the potential impact that particle phase chemistry can have on biogenic SOA formation and the particle size range where this chemistry becomes important.

Published: January 2017

Abstract. In order to explore coupling between the thermosphere and ionosphere and to address the lack of data relating to thermospheric neutral winds and temperatures over the African sector, a new system of instruments was installed at the Oukaïmeden Observatory located in the high Atlas Mountains, 75 km south of Marrakesh, Morocco (31.206° N, 7.866° W, 22.84° N magnetic). In this work we present the first multi-year results of the climatology of meridional and zonal winds obtained during the period from January 2014 to February 2016, including observations from 648 nights. The measurements are obtained using an imaging Fabry–Pérot interferometer, which measures the 630.0 nm emissions caused by dissociative recombination of O2+. The basic climatology of the winds is as expected, showing zonal winds that are strongly eastward in the early evening just after sunset with a speed of 50 to 100 m s−1 decreasing in magnitude, and reversing directions in the local summer months, towards sunrise. The meridional winds are slightly poleward in the early evening during the local winter, before reversing directions around 21:00 LT. In the local summer months, the meridional winds are equatorward for the entire night, reaching a maximum equatorward speed of 75 m s−1. We compare the observed climatologies of neutral winds to that provided by the recently updated Horizontal Wind Model (HWM14) in order to validate that model's predictions of the thermospheric wind patterns over the eastern portion of Africa. The model captures much of the features in the observational climatologies. The most notable exception is for the zonal winds during local summer, when the maximum eastward wind in the observations occurs approximately 4 h later than seen in the model results.
Effect of soil saturation on denitrification in a grassland soil

Published: January 2017

Abstract. Nitrous oxide (N2O) is of major importance as a greenhouse gas and precursor of ozone (O3) destruction in the stratosphere mostly produced in soils. The soil emitted N2O is predominantly derived from denitrification and to a smaller extent, nitrification in soils, both processes controlled by environmental factors and their interactions, and are influenced by agricultural management. Soil water content expressed as water filled pore space (WFPS) is a major controlling factor of emissions and its interaction with compaction, has not been studied at the micropore scale. A laboratory incubation was carried out at different saturation levels for a grassland soil and emissions of N2O and N2 were measured as well as the isotopomers of N2O. We found that fluxes variability was larger in the less saturated soils probably due to nutrient distribution heterogeneity created from soil cracks and consequently nutrient hot spots. The results agreed with denitrification as the main source of fluxes at the highest saturations, but nitrification could have occurred at the lower saturation, even though moisture was still high (71 % WFSP). The isotopomer data showed isotopic similarities in the wettest treatments vs the two drier ones; and results agreed with previous findings where it is clear there are 2 N-pools with different dynamics: added N producing intense denitrification, vs soil N resulting in less isotopic fractionation.
Insignificant effects of elevated CO2 on bacterioplankton community in a eutrophic coastal mesocosm experiment
Authors: Lin Xin , Huang Ruiping , Li Yan , Wu Yaping , Hutchins David A. , Dai Minhan , Gao Kunshan
Published: January 2017

Abstract. There is increasing concern about the effects of ocean acidification on marine biogeochemical and ecological processes and the organisms that drive them, including marine bacteria. Here, we examine the effects of elevated CO2 on bacterioplankton community during a mesocosm experiment using an artificial phytoplankton community in subtropical, eutrophic coastal waters of Xiamen, Southern China. We found that the elevated CO2 hardly altered the network structure of the bacterioplankton taxa present with high abundance but appeared to reassemble the community network of taxa present with low abundance by sequencing of the bacterial 16S rRNA gene V3-V4 region and ecological network analysis. This led to relatively high resilience of the whole bacterioplankton community to the elevated CO2 level and associated chemical changes. We also observed that the Flavobacteriia group, which plays an important role in the microbial carbon pump, showed higher relative abundance under elevated CO2 condition during the developing stage of the phytoplankton bloom in the mesocosms. Compared to the CO2 enrichment, the phytoplankton bloom had more pronounced effects on baterioplankton community structure. Our results suggest that the bacterioplankton community in this subtropical, high nutrient coastal environment is relatively insensitive to changes in seawater carbonate chemistry.
Ökonomische und politische Prinzipien im Umbruch: die „Quantitative Revolution“ der Geographie als Spiegel bürgerlichen Bewusstseins
Authors: Eisel Ulrich
Published: January 2017

Abstract. The quantitive revolution in geography was the methodological expression of a shift in paradigm. Nomological thinking took over from the idiographic approach of classic geography. The classic paradigm had been that of a desirable identity of concrete working, active humans with their concrete natural surroundings: landscape was imagined as Lebensraum. The logic of industrial production processes contrasts with this; it creates an identity of scientifically analysed human work sequences with machines, and it thus represents a form of adapting to nature by abstracting holistically integrated ways of carrying out work. The geographical paradigm had no theoretical tools with which to approach this relationship between humans and nature. With regard to the theoretical ideas underlying it, this methodological change corresponds, on the one hand, to the transition from following a humanist concept of the individual, which guides idiographic thinking, to using a democratic concept of the individual, which correlates with the principles of experiment-based empirical sciences. On the other hand, geography's move towards an abstract concept of space reflects the degree to which industrial production methods are abstracted. The spatial approach, the behavioural approach, and humanistic geography are interpreted and contrasted with the idiographic paradigm within this coordinate system.
Conservative interpolation between general spherical meshes
Authors: Kritsikis Evaggelos , Aechtner Matthias , Meurdesoif Yann , Dubos Thomas
Published: January 2017

Abstract. An efficient, local, explicit, second-order, conservative interpolation algorithm between spherical meshes is presented. The cells composing the source and target meshes may be either spherical polygons or latitude–longitude quadrilaterals. Second-order accuracy is obtained by piece-wise linear finite-volume reconstruction over the source mesh. Global conservation is achieved through the introduction of a supermesh, whose cells are all possible intersections of source and target cells. Areas and intersections are computed exactly to yield a geometrically exact method. The main efficiency bottleneck caused by the construction of the supermesh is overcome by adopting tree-based data structures and algorithms, from which the mesh connectivity can also be deduced efficiently.The theoretical second-order accuracy is verified using a smooth test function and pairs of meshes commonly used for atmospheric modelling. Experiments confirm that the most expensive operations, especially the supermesh construction, have O(NlogN) computational cost. The method presented is meant to be incorporated in pre- or post-processing atmospheric modelling pipelines, or directly into models for flexible input/output. It could also serve as a basis for conservative coupling between model components, e.g., atmosphere and ocean.
MSWEP: 3-hourly 0.25° global gridded precipitation (1979–2015) by merging gauge, satellite, and reanalysis data

Published: January 2017

Abstract. Current global precipitation (P) datasets do not take full advantage of the complementary nature of satellite and reanalysis data. Here, we present Multi-Source Weighted-Ensemble Precipitation (MSWEP) version 1.1, a global P dataset for the period 1979–2015 with a 3-hourly temporal and 0.25° spatial resolution, specifically designed for hydrological modeling. The design philosophy of MSWEP was to optimally merge the highest quality P data sources available as a function of timescale and location. The long-term mean of MSWEP was based on the CHPclim dataset but replaced with more accurate regional datasets where available. A correction for gauge under-catch and orographic effects was introduced by inferring catchment-average P from streamflow (Q) observations at 13 762 stations across the globe. The temporal variability of MSWEP was determined by weighted averaging of P anomalies from seven datasets; two based solely on interpolation of gauge observations (CPC Unified and GPCC), three on satellite remote sensing (CMORPH, GSMaP-MVK, and TMPA 3B42RT), and two on atmospheric model reanalysis (ERA-Interim and JRA-55). For each grid cell, the weight assigned to the gauge-based estimates was calculated from the gauge network density, while the weights assigned to the satellite- and reanalysis-based estimates were calculated from their comparative performance at the surrounding gauges. The quality of MSWEP was compared against four state-of-the-art gauge-adjusted P datasets (WFDEI-CRU, GPCP-1DD, TMPA 3B42, and CPC Unified) using independent P data from 125 FLUXNET tower stations around the globe. MSWEP obtained the highest daily correlation coefficient (R) among the five P datasets for 60.0 % of the stations and a median R of 0.67 vs. 0.44–0.59 for the other datasets. We further evaluated the performance of MSWEP using hydrological modeling for 9011 catchments (< 50 000 km2) across the globe. Specifically, we calibrated the simple conceptual hydrological model HBV (Hydrologiska Byråns Vattenbalansavdelning) against daily Q observations with P from each of the different datasets. For the 1058 sparsely gauged catchments, representative of 83.9 % of the global land surface (excluding Antarctica), MSWEP obtained a median calibration NSE of 0.52 vs. 0.29–0.39 for the other P datasets. MSWEP is available via http://www.gloh2o.org.
Wave simulation for the design of an innovative quay wall: the case of Vlorë Harbour
Authors: Antonini Alessandro , Archetti Renata , Lamberti Alberto
Published: January 2017

Abstract. Sea states and environmental conditions are basic data for the design of marine structures. Hindcasted wave data have been applied here with the aim of identifying the proper design conditions for an innovative quay wall concept. In this paper, the results of a computational fluid dynamics model are used to optimise the new absorbing quay wall of Vlorë Harbour (Republic of Albania) and define the design loads under extreme wave conditions. The design wave states at the harbour entrance have been estimated analysing 31 years of hindcasted wave data simulated through the application of WaveWatch III. Due to the particular geography and topography of the Bay of Vlorë, wave conditions generated from the north-west are transferred to the harbour entrance with the application of a 2-D spectral wave module, whereas southern wave states, which are also the most critical for the port structures, are defined by means of a wave generation model, according to the available wind measurements. Finally, the identified extreme events have been used, through the NewWave approach, as boundary conditions for the numerical analysis of the interaction between the quay wall and the extreme events. The results show that the proposed method, based on numerical modelling at different scales from macro to meso and to micro, allows for the identification of the best site-specific solutions, also for a location devoid of any wave measurement. In this light, the objectives of the paper are two-fold. First, they show the application of sea condition estimations through the use of wave hindcasted data in order to properly define the design wave conditions for a new harbour structure. Second, they present a new approach for investigating an innovative absorbing quay wall based on CFD modelling and the NewWave theory.
Building Asset Value Mapping in Support of Flood Risk Assessment:
A Case Study of Shanghai, China
Authors: Wu Jidong , Wang Xu , Koks Elco
Published: January 2017

Abstract. Exposure is an integral part of any natural disaster risk assessment. As one of the consequences of natural disasters, damage to buildings is one of the most important concerns. As such, estimates of the building stock and the values at risk can assist natural disaster risk management, including determining the damage extent and severity. Unfortunately, only little information about building asset value is readily available in most countries (especially its spatial distributions) including in China, given that the statistical data on building floor area (BFA) is collected by administrative unities in China. In order to bridge the gap between aggregated census statistical buildings floor-area data to geo-coded building asset value data, this article introduces a methodology for a city-scale building asset value mapping using Shanghai as an example. It consists of a census BFA disaggregation (downscaling) by means of a building footprint map extracted from high-resolution remote sensing data and LandScan population density data, and a financial appraisal of building asset values. A validation with statistical data confirms the feasibility of the modelled building storey. The example of the use of the developed building asset value map in exposure assessment of a flood scenario of Shanghai demonstrated that the dataset offers immense analytical flexibility for flood risk assessment. The method used in this paper is transferable to be applied in other cities of China for building asset value mapping.
Assessing the extreme risk of coastal inundation due to climate change: A case study of Rongcheng, China
Authors: Feng Aiqing , Gao Jiangbo , Wu Shaohong , Li Yanzhong , Yue Xiliu
Published: January 2017

Abstract. Extreme water levels, caused by the joint occurrence of storm surges and high tides, always lead to super floods along coastlines. Given the ongoing climate change, this study explored the risk of future sea-level rise on the extreme inundation by combining P-III model and losses assessment model. Taking Rongcheng as a case study, the integrated risk of extreme water levels was assessed for 2050 and 2100 under three Representative Concentration Pathways (RCP) scenarios of 2.6, 4.5, and 8.5. Results indicated that the increase in total direct losses would reach an average of 60 % in 2100 as a 0.82 m sea-level rise under RCP 8.5. In addition, affected population would be increased by 4.95 % to 13.87 % and GDP (Gross Domestic Product) would be increased by 3.66 % to 10.95 % in 2050 while the augment of affected population and GDP in 2100 would be as twice as in 2050. Residential land and farmland would be under greater flooding risk in terms of the higher exposure and losses than other land-use types. Moreover, this study indicated that sea-level rise shortened the recurrence period of extreme water levels significantly and extreme events would become common. Consequently, the increase in frequency and possible losses of extreme flood events suggested that sea-level rise was very likely to exacerbate the extreme risk of coastal zone in future.

La Asamblea General de las Naciones Unidas impulsó en septiembre de 2015 una nueva Agenda de Desarrollo con el lanzamiento de los Objetivos de Desarrollo Sostenible (ODS) —también llamada Agenda 2030—. Los ODS, que sustituyen a los caducos Objetivos de Desarrollo del Milenio (ODM), tienen como objetivo reducir la pobreza mundial a través de la reducción de la desigualdad económica y social. Por otro lado, las negociaciones entre los Estados Unidos y la Unión Europea para el acuerdo de Asociación Transatlántica para el Comercio y la Inversión (TTIP) pretenden crear la mayor relación económica y comercial a nivel mundial. El objetivo de este artículo es el de analizar en qué medida la firma del TTIP contribuirá a conseguir satisfactoriamente los ODS y si se está teniendo en cuenta la nueva Agenda de Desarrollo en las negociaciones de este importante tratado entre los Estados Unidos y la Unión Europea.
Metachronous Solitary Metastasis to the Thyroid Gland from Squamous Cell Carcinoma of the Lung: A Case Report and Literature Review

Published: January 2017

Introduction

Non-small cell lung cancer presents at an advanced stage at diagnosis in two-thirds of cases. The most frequent metastatic sites are the central nervous system, adrenal glands and bones. By contrast, the thyroid gland is an extremely rare site of dissemination.

Case description

A 64-year-old Caucasian man previously treated with radiosurgery and brain metastasectomy followed by right middle lobectomy for a squamous cell lung carcinoma had a metachronous solitary metastasis to the thyroid gland, as confirmed by fine-needle aspiration cytology and open biopsy. He underwent curative radiotherapy, with an initial response. At 9 months’ follow-up the tumor relapsed both in the thyroid and the lung.

Discussion and conclusions

Review of the literature confirmed that thyroid metastasis from lung cancer is very uncommon in clinical practice. No data on the role of surgery or curative radiotherapy in thyroid metastasis are available because of the lack of prospective studies addressing the impact on survival of these treatment strategies either alone or in combination. In the case described here, radical treatment with radiotherapy allowed to obtain a modest benefit in terms of relapse-free survival. A diagnosis of metastasis to the thyroid gland should be suspected in patients who present a thyroid nodule or suggestive imaging findings when there is a history of malignancy, including lung cancer. Indeed, an early diagnosis allows to pursue radical treatment that, in selected patients, could lead to long-term survival.
Migración del Triángulo Norte de Centroamérica a los Estados Unidos de América

Published: January 2017

Los países del Triángulo Norte de Centroamérica: Guatemala, El Salvador y Honduras, abarcan una extensión territorial de 242.4 mil km2 y en las últimas seis décadas han incrementado ostensiblemente su población, pasando de 6.8 millones en 1950 a 30.9 millones en el 2015, incrementándose en 4.5 veces. En la actualidad los países del Triángulo Norte generan los mayores flujos migratorios hacia los Estados Unidos de América, en el siguiente orden: El Salvador, Guatemala y Honduras, contribuyendo con alrededor del 85% de la población de origen hispano centroamericano (siendo 4 millones de personas en el 2012) residen en ese destino. Este trabajo quiere mostrar un panorama actual de la migración internacional de los países del Triángulo Norte de Centroamérica hacia los Estados Unidos de América, siendo una sistematización de información del fenómeno migratorio de los países de la subregión, tomando en cuenta las fuentes de datos e información desde el origen, el tránsito y el destino, desde la perspectiva de la demografía. Las fuentes de información secundarias utilizadas son las bibliográficas, los informes, memorias, artículos, reportajes y otras experiencias de investigación, aunque la perspectiva demográfica conduce que las principales fuentes de datos son estadísticas y nuestro enfoque está en la búsqueda, clasificación, obtención, generación y análisis de los datos, localizadas en los países de origen, en tránsito y destino, tales como los Censos de Población, Encuestas de Hogares, Estadísticas Migratorias, Estadísticas de Aprehensión y Deportación, Encuestas Especiales de Migración y las Estimaciones de Población Migrante en tránsito y en el destino como también los no autorizados y los posibles aplicantes a programas de regularización.Revista Población y Desarrollo: Argonautas y Caminantes Vol.12, 2016: 25-38
2015: Auge Laboral en la Región Metropolitana Guadalajara
Authors: Parra Ruiz José María , Gámez Frías Emilia
Published: January 2017

En 2015, la población de la Región Metropolitana Guadalajara (RMG), registra un auge ocupacional. Más de 73 mil nuevas ocupaciones fueron generadas por nueve ramas de actividad económica. Sin embargo, estas ocupaciones resultan insuficientes para cubrir las necesidades que demanda la población en edad de trabajar (15 y más años de edad). Cabe señalar que el mayor crecimiento lo experimenta la fuerza de trabajo en términos generales y por rama de actividad económica donde labora. Pero a la vez, dicha fuerza de trabajo incrementó su compra-venta bajo disímbolas condiciones de precariedad. Por lo tanto se observa que el mayor nivel de ocupación se realiza bajo condiciones de precariedad laboral (en aras de incrementar ganancias) lo cual contraviene el postulado constitucional establecido en el artículo 1233. Ello, conlleva a incrementar la inestabilidadheterogeneidad laboral en la población de la RMG, principalmente de la fuerza de trabajo. Cabe señalar que el análisis de la información estadística: Encuesta Nacional del Empleo y la Ocupación (ENOE, segundo trimestre de cada año del periodo) 4, se fundamenta en la perspectiva teórica conceptual de la economía política y la sociología del trabajo.Revista Población y Desarrollo: Argonautas y Caminantes Vol.12, 2016: 41-50
Análisis Comparativo de la Fecundidad en Provincias de la Argentina, 2001
Authors: Tisnés Adela , Salazar Acosta Luisa María
Published: January 2017

Esta investigación comprende un análisis comparativo de la fecundidad en tres espacios geográficos: la Provincia de Misiones, la ciudad Autónoma de Buenos Aires y el Total del País, para observar las pautas que caracterizan a cada uno de ellos. La idea subyacente a la selección de estas áreas, es presentar un contraste bien notable en los indicadores socio- económicos obtenidos, y ver, entre otras cosas, si esas diferencias planteadas, tienen repercusión o incidencia en la fecundidad. Se partirá entonces, de poblaciones bien diferentes desde diversos aspectos.Revista Población y Desarrollo: Argonautas y Caminantes Vol.12, 2016: 133-143
Redes sociais e turismo: reflexões no contexto do desenvolvimento regional
Authors: Minasi Sarah Marroni , Da Silveira Rogério Leandro Lima
Published: January 2017

O estudo das redes sociais é relevante para melhor compreender os atores sociais e suas relações e interações sociais. Assim, procura-se entender o modo como se articulam os atores, os conflitos presentes nas relações sociais, entre outros temas. Neste ensaio se aborda a relação das redes sociais e o turismo. Buscou-se evidenciar as correlações entre a formação de redes sociais, a expansão da atividade turística e o desenvolvimento regional. Apresenta-se como objetivo uma reflexão sobre a relação entre a configuração de redes sociais e os agentes do turismo na dinamização da atividade turística e promoção do desenvolvimento regional. Portanto, esse artigo se constitui em uma discussão teórica baseada na revisão bibliográfica produzida sobre a temática em foco. Notou-se que a revisão do papel de cada agente social do turismo nos processos de apropriação dos territórios turísticos e das redes regionais estabelecidas favorece uma nova instância de gestão para o desenvolvimento do setor. Portanto, ações de cooperação em rede estão diretamente relacionadas com o fortalecimento da gestão no âmbito regional, a descentralização da gestão, e a promoção de dinâmicas do desenvolvimento regional.
Turismo e Desastres: o caso das enchentes e deslizamentos na destinação turística Costa Verde e Mar – Santa Catarina (Brasil)
Authors: Rocha Marcelo Mariano , Mattedi Marcos Antônio
Published: January 2017

No presente trabalho se apresentam as implicações dos desastres sobre a atividade turística, em especial a abordagem da destinação turística Costa Verde e Mar, em Santa Catarina (Brasil). A destinação encontra-se localizada na Bacia Hidrográfica do Vale do Itajaí, uma região suscetível a desastres, e com potencial para provocar sérios impactos para o trade1 turístico. Para analisar essa problemática, a pesquisa teve como metodologia o levantamento de dados qualitativos e quantitativos, bem como a análise de documentos oficiais sobre o turismo e os desastres em Santa Catarina. Concluiu-se que a atividade turística explorada na destinação possuiu total condição de ser afetada pelos desastres em virtude das condições ambientais, geológicas e hidrológicas existentes na região do Vale do Itajaí. Desta forma, a efetivação desse fenômeno poderia proporcionar um grande prejuízo para o trade, bem como para a economia da destinação turística.
Cenários arqueológicos e os festivais pré-colombianos como mediadores de práticas turísticas
Authors: Santos Jr Sergio Antônio
Published: January 2017

O presente artigo é constituído de três textos distintos, mas que se combinam por um denominador comum: trata-se de festivais pré-colombianos, enquanto as últimas manifestações culturais e ritualísticas indígenas nas Américas, com as respectivas ocorrências em seus sítios arqueológicos, onde originalmente foram idealizados para tal feito. O objetivo é descrever estes eventos de interesse para o turismo: “festival Tapati, Inti Raymi e festival de Vida e Morte”, e sua intrincada relação com a natureza do lugar. Cabe destacar que estes dois quesitos enredados são considerados pela United Nations Educational Scientific and Cultural Organization – UNESCO, como Patrimônios Culturais da Humanidade, no que se refere ao material e ao imaterial. A estratégia teórico-metodológica desta abordagem compreende dois processos: o primeiro, destaca a importância destes lugares, segundo parecer da Assessoria de Avaliação da UNESCO e de seus documentos disponibilizados em relação ao sítio; o segundo, inspira-se na etnografia urbana, onde foram recolhidas impressões e relatos de alguns viajantes, pesquisadores, entidades público/privadas e do próprio autor.

Contribuições de base geográfica cultural para o estudo do turismo em comunidades locais
Authors: Nitsche Letícia Bartoszeck , Bahl Miguel
Published: January 2017

Levando em conta a problemática que se coloca a respeito do turismo com seus efeitos sobre as comunidades e sua cultura, o presente trabalho1 tem o objetivo de identificar possíveis contribuições da geografia cultural que possam ser discutidas no estudo do turismo. Desta forma, busca-se colaborar com a construção de um referencial teórico-prático que possa orientar novas pesquisas sobre as transformações do turismo em relação às comunidades locais. A metodologia da pesquisa é a bibliográfica, para a qual foram investigadas referências da área da geografia cultural, geografia humanista, representações em geografia, e sobre a área de conhecimento do turismo na sua interface epistemológica. Os resultados preliminares da pesquisa apresentam algumas reflexões que buscam elucidar a discussão epistemológica inerente ao turismo e a abertura para outras correntes de pensamento científico como a fenomenológica, que por sua vez, surge também no referencial epistemológico da geografia cultural, sendo apontada neste artigo como um elo comum entre as análises aqui pretendidas. Num segundo momento, expõem-se aspectos sobre a trajetória da geografia cultural com suas correntes teóricas e metodológicas, e em seguida, se iniciam as reflexões sobre as possíveis contribuições desta vertente geográfica para as pesquisas em turismo. A contribuição da geografia cultural para este trabalho aponta o aprofundamento para o enfoque humanista de base fenomenológica e seus desdobramentos nos estudos sobre a percepção dos moradores de locais receptores de turistas, em relação ao seu espaço de vivência.

Primary Intraprostatic Synovial Sarcoma
Authors: Olofson Andrea M. , Linos Konstantinos
Published: January 2017

Primary intraprostatic synovial sarcoma is a rare presentation of an otherwise well-studied disease, and it is one of the few primary sarcomas to occur in the prostate. Ancillary diagnostic techniques including immunohistochemistry and molecular genetics are useful to establish a definitive diagnosis. Despite its unorthodox location, it shares histologic and molecular genetic characteristics with tumors found elsewhere in the body. Most notably, the chromosomal translocation t(X;18)(p11;q11) encodes a chimeric transcription-activating protein, SS18-SSX, which has been identified as the primary driver mutation. The SS18-SSX fusion gene provides a consistent and dependable means of establishing a definitive diagnosis via reverse transcription–polymerase chain reaction or fluorescence in situ hybridization. Recent studies have continued to provide insight into the oncogenesis of this disease. The goal of this review is to elaborate on the clinicopathologic characteristics and underline those techniques that best facilitate the diagnosis of primary intraprostatic synovial sarcoma.
