Investigating interdecadal salinity changes in the Baltic Sea in a 1850–2008 hindcast simulation
Authors: Radtke Hagen , Brunnabend Sandra-Esther , Gräwe Ulf , Meier H. E. Markus
Published: August 2020

Abstract. Interdecadal variability in the salinity of the Baltic Sea is dominated by a 30-year cycle with a peak-to-peak amplitude of around 0.4 g kg−1 at the surface.
Such changes may have substantial consequences for the ecosystem, since species are adapted to a suitable salinity range and may experience habitat shifts.
It is therefore important to understand the drivers of such changes.
We use both analysis of empirical data and a numerical model reconstruction for the period of 1850–2008 to explain these interdecadal changes.
The model explains 93 % and 52 % of the variance in the observed interdecadal salinity changes at the surface and the bottom, respectively, at an oceanographic station at Gotland Deep.
It is known that the 30-year periodicity coincides with a variability in river runoff.
Periods of enhanced runoff are followed by lower salinities.
We demonstrate, however, that the drop in mean salinity cannot be understood as a simple dilution of the Baltic Sea water by freshwater.
Rather, the 30-year periodicity in river runoff occurs synchronously with a substantial variation in salt water import across Darss Sill.
Fewer strong inflow events occur in periods of enhanced river runoff.
This reduction in the import of high-salinity water is the main reason for the freshening of the water below the permanent halocline.
In the bottom waters, the variation in salinity is larger than at the surface.
As a consequence, the surface layer salinity variation is caused by a combination of both effects: a direct dilution by river water and a reduced upward diffusion of salt as a consequence of reduced inflow activity.
Our findings suggest that the direct dilution effect is responsible for 27 % of the salinity variations only.
It remains unclear whether the covariation in river runoff and inflow activity are only a coincidental correlation during the historical period or whether a mechanistic link exists between the two quantities, e.g. whether both are caused by the same atmospheric patterns.
Sensitivity of mid-Pliocene climate to changes in orbital forcing and PlioMIP's boundary conditions
Authors: Samakinwa Eric , Stepanek Christian , Lohmann Gerrit
Published: August 2020

Abstract. We compare results obtained from modeling the mid-Pliocene warm period using the Community Earth System Models (COSMOS, version: COSMOS-landveg
r2413, 2009) with the two different modeling methodologies and sets of boundary conditions prescribed for the two phases of the Pliocene Model
Intercomparison Project (PlioMIP), tagged PlioMIP1 and PlioMIP2. Here, we bridge the gap between our contributions to PlioMIP1 (Stepanek and Lohmann, 2012)
and PlioMIP2 (Stepanek et al., 2020). We highlight some of the effects that differences in the chosen mid-Pliocene model setup (PlioMIP2 vs. PlioMIP1)
have on the climate state as derived with COSMOS, as this information will be valuable in the framework of the model–model and
model–data comparison within PlioMIP2. We evaluate the model sensitivity to improved mid-Pliocene boundary conditions using PlioMIP's core
mid-Pliocene experiments for PlioMIP1 and PlioMIP2 and present further simulations in which we test model sensitivity to variations in
paleogeography, orbit, and the concentration of CO2. Firstly, we highlight major changes in boundary conditions from PlioMIP1 to PlioMIP2 and also the challenges recorded from the initial effort. The
results derived from our simulations show that COSMOS simulates a mid-Pliocene climate state that is 0.29 ∘C colder in PlioMIP2 if
compared to PlioMIP1 (17.82 ∘C in PlioMIP1, 17.53 ∘C in PlioMIP2; values based on simulated surface skin
temperature). On the one hand, high-latitude warming, which is supported by proxy evidence of the mid-Pliocene, is underestimated in simulations of both
PlioMIP1 and PlioMIP2. On the other hand, spatial variations in surface air temperature (SAT), sea surface temperature (SST), and the
distribution of sea ice suggest improvement of simulated SAT and SST in PlioMIP2 if employing the updated paleogeography. Our PlioMIP2 mid-Pliocene
simulation produces warmer SSTs in the Arctic and North Atlantic Ocean than those derived from the respective PlioMIP1 climate state. The difference in
prescribed CO2 accounts for 0.5 ∘C of temperature difference in the Arctic, leading to an ice-free summer in the PlioMIP1
simulation, and a quasi ice-free summer in PlioMIP2. Beyond the official set of PlioMIP2 simulations, we present further simulations and analyses
that sample the phase space of potential alternative orbital forcings that have acted during the Pliocene and may have impacted geological
records. Employing orbital forcing, which differs from that proposed for PlioMIP2 (i.e., corresponding to pre-industrial conditions) but falls into
the mid-Pliocene time period targeted in PlioMIP, leads to pronounced annual and seasonal temperature variations. Our result identifies the
changes in mid-Pliocene paleogeography from PRISM3 to PRISM4 as the major driver of the mid-Pliocene warmth within PlioMIP and not the minor
differences in forcings.
A comprehensive oceanographic dataset of a subpolar, mid-latitude broad fjord: Fortune Bay, Newfoundland, Canada
Authors: Donnet Sebastien , Lazure Pascal , Ratsimandresy Andry , Han Guoqi
Published: August 2020

Abstract. While the dynamics of narrow fjords, i.e. narrow with
respect to their internal Rossby radius, have been widely studied, it is
only recently that interest in studying the physics of broad fjords was sparked
due to their importance in glacial ice melting (in Greenland, especially).
Here, we present a comprehensive set of data collected in Fortune Bay, a
broad, mid-latitude fjord located on the northwest Atlantic shores. Aside
from being wide (15–25 km width) and deep (600 m at its deepest), Fortune
Bay also has the characteristics of having steep slopes, having weak tides and
being strongly stratified from spring to fall. Thus, and since strong
along-shore winds also characterize the region, this system is prone to
interesting dynamics, generally taking the form of transient upwelling and
downwelling travelling along its shores, similar to processes encountered in
broad fjords of higher latitudes. The dataset collected to study those
dynamics consists of water column physical parameters (temperature,
salinity, currents and water level) and atmospheric forcing (wind speed and
direction, atmospheric pressure, air temperature, and solar radiation) taken
at several points around the fjord using oceanographic moorings and
land-based stations. The program lasted 2 full years and achieved a good
data return of 90 %, providing a comprehensive dataset not only for
Fortune Bay studies but also for the field of broad fjord studies. The data
are available publically from the SEANOE repository (https://doi.org/10.17882/62314; Donnet and Lazure, 2020).
Ship-borne measurements of XCO2, XCH4, and XCO above the Pacific Ocean and comparison to CAMS atmospheric analyses and S5P/TROPOMI

Abstract. Measurements of atmospheric column-averaged dry-air mole fractions of carbon dioxide (XCO2), methane (XCH4), and carbon monoxide (XCO) have been collected across the Pacific ocean during the Measuring Ocean REferences 2 (MORE-2) campaign in June 2019. We deployed a ship-borne variant of the EM27/SUN Fourier Transform Spectrometer (FTS) on board the German research vessel Sonne which, during MORE-2, crossed the Pacific ocean from Vancouver, Canada, to Singapore. Equipped with a specially manufactured fast solar tracker, the FTS operated in direct-sun viewing geometry during the ship cruise reliably delivering solar absorption spectra in the shortwave infrared spectral range (4000 to 11 000 1/cm). After filtering and bias correcting the dataset, we report on XCO2, XCH4, and XCO measurements for 22 days along a trajectory that largely aligns with 30° N of latitude between 140° W and 120° E of longitude. The dataset has been scaled to the Total Carbon Column Observing Network (TCCON) station in Karlsruhe, Germany, before and after the MORE-2 campaign through side-by-side measurements. The precision for hourly means of XCO2, XCH4, and XCO during the campaign is found 0.24 ppm, 1.1 ppb, and 0.75 ppb, respectively. Comparing concentration fields analysed by the Copernicus Atmosphere Monitoring Service (CAMS) to our data, we find excellent agreement of 0.52 ± 0.31 ppm for XCO2, 0.9 ± 4.1 ppb for XCH4, and 3.2 ± 3.4 ppb for XCO (mean difference ± standard deviation of differences for entire record). Likewise, we find excellent agreement to within 2.2 ± 6.6 ppb with the XCO observations of the TROPOspheric MOnitoring Instrument (TROPOMI) on the Sentinel-5 Precursor satellite (S5P). The ship-borne measurements are accessible at https://doi.org/10.1594/PANGAEA.917240 (Knapp et al., 2020).
The ABC-DA system (v1.4): a variational data assimilation system for convective-scale assimilation research with a study of the impact of a balance constraint
Authors: Bannister Ross Noel
Published: August 2020

Abstract. Following the development of the simplified atmospheric convective-scale
“toy” model (the ABC model, named after its three key parameters:
the pure gravity wave frequency A, the controller of the acoustic
wave speed B, and the constant of proportionality between pressure
and density perturbations C), this paper introduces its associated
variational data assimilation system, ABC-DA. The purpose of ABC-DA
is to permit quick and efficient research into data assimilation methods
suitable for convective-scale systems. The system can also be used
as an aid to teach and demonstrate data assimilation principles. ABC-DA is flexible and configurable, and is efficient enough to be
run on a personal computer. The system can run a number of assimilation
methods (currently 3DVar and 3DFGAT have been implemented), with user
configurable observation networks. Observation operators for direct
observations and wind speeds are part of the current system, and these
can, for example, be expanded relatively easily
to include operators for Doppler winds. A key feature
of any data assimilation system is how it specifies the background
error covariance matrix. ABC-DA uses a control variable transform
method to allow this to be done efficiently. This version of ABC-DA
mirrors many operational configurations by modelling multivariate
error covariances with uncorrelated control parameters, each with
special uncorrelated spatial patterns. The software developed performs (amongst other things) model runs, calibration
tasks associated with the background error covariance matrix, testing
and diagnostic tasks, single data assimilation runs, and multi-cycle assimilation/forecast
experiments, and it also has associated visualisation software. As a demonstration, the system is used to tackle a scientific question
concerning the role of geostrophic balance (GB) to model background
error covariances between mass and wind fields. This question arises
because although GB is a very useful mechanism that is successfully
exploited in larger-scale assimilation systems, its use is questionable
at convective scales due to the typically larger Rossby numbers where
GB is not so relevant. A series of identical twin experiments is done
in cycled assimilation configurations. One experiment exploits GB
to represent mass–wind covariances in a mirror of an operational set-up
(with use of an additional vertical regression (VR) step, as used
operationally). This experiment performs badly where error accumulates
over time. Two further experiments are done: one that does not use
GB and another that does but without the VR step. Turning off GB
impairs the performance, and turning off VR improves the performance
in general. It is concluded that there is scope to further improve
the way that the background error covariance matrices are represented
at convective scale.
Ideas for further possible developments of ABC-DA are discussed.
Relative importance of increased atmospheric CO2 concentration and local moisture deficit to hot extremes
Authors: Chen Ajiao , Guan Huade , Batelaan Okke
Published: August 2020

Abstract. This study identifies which factor, increased atmospheric CO2 concentration or local moisture deficit, dominates the temporal occurrence of hot extremes at the global scale. The wavelet decomposed GRACE Terrestrial Water Storage (TWS) is for the first time applied in examining the relationship between soil moisture (θ) and number of hot days in the hottest month (NHD). It reveals stronger θ–NHD relationships over larger areas than other commonly used soil moisture proxies (i.e., standardized precipitation index (SPI) and model derived product). During the study period 1985–2015, hot extreme occurrence with a dominant influence from increased atmospheric CO2 concentration is mainly observed in South America, Africa and Asia, while soil moisture deficit dominates the occurrence of hot extremes in larger areas, including parts of North America, West Europe, Australia, Southeast Asia and South Africa. Global action in reducing emissions will support combating hot extremes. In addition, important attention should be directed to address, e.g. by adaptive land management, the increasing moisture deficit in some regions.
A new method to assess mesoscale contributions to meridional heat transport in the North Atlantic Ocean
Authors: Delman Andrew , Lee Tong
Published: August 2020

Abstract. The meridional heat transport (MHT) in the North Atlantic is critically important to climate variability and the global overturning circulation. A wide range of ocean processes contribute to North Atlantic MHT, ranging from basin-scale overturning and gyre motions to mesoscale instabilities (such as eddies). However, previous analyses of “eddy” MHT in the region have mostly focused on the contributions of time-variable velocity and temperature, rather than considering the association of MHT with distinct spatial scales within the basin. In this study, a zonal spatial-scale decomposition separates large-scale from mesoscale velocity and temperature contributions to MHT, in order to characterize the physical processes driving MHT. Using this approach, we found that the mesoscale contributions to the time-mean and interannual/decadal (ID) variability of MHT in the latitude range 39–45∘ N are larger than large-scale horizontal contributions, though smaller than the overturning contributions. Considering the 40∘ N transect as a case study, large-scale ID variability is mostly generated close to the western boundary. In contrast, most ID MHT variability associated with mesoscales originates in two distinct regions: a western boundary region (70–60∘ W) associated with 1- to 4-year interannual variations and an interior region (50–35∘ W) associated with decadal variations. Surface eddy kinetic energy is not a reliable indicator of high MHT episodes, but the large-scale meridional temperature gradient is an important factor, by influencing the local temperature variance as well as the local correlation of velocity and temperature. Most of the mesoscale contribution to MHT at 40∘ N is associated with transient and propagating processes, but stationary mesoscale structures explain most of the mesoscale MHT south of the Gulf Stream separation, highlighting the differences between the temporal and spatial decomposition of meridional temperature fluxes.
Global sea level reconstruction for 1900–2015 reveals regional variability in ocean dynamics and an unprecedented long weakening in the Gulf Stream flow since the 1990s
Authors: Ezer Tal , Dangendorf Sönke
Published: August 2020

Abstract. A new monthly global sea level reconstruction for 1900–2015 was
analyzed and compared with various observations to examine regional
variability and trends in the ocean dynamics of the western North Atlantic
Ocean and the US East Coast. Proxies of the Gulf Stream (GS) strength in
the Mid-Atlantic Bight (GS-MAB) and in the South Atlantic Bight (GS-SAB)
were derived from sea level differences across the GS. While decadal
oscillations dominate the 116-year record, the analysis showed an
unprecedented long period of weakening in the GS flow since the late 1990s.
The only other period of long weakening in the record was during the
1960s–1970s, and red noise experiments showed that is very unlikely that
those just occurred by chance. Ensemble empirical mode decomposition (EEMD)
was used to separate oscillations at different timescales, showing that the
low-frequency variability of the GS is connected to the Atlantic
Multi-decadal Oscillation (AMO) and the Atlantic Meridional Overturning
Circulation (AMOC). The recent weakening of the reconstructed GS-MAB was
mostly influenced by weakening of the upper mid-ocean transport component of
AMOC as observed by the RAPID measurements for 2005–2015. Comparison between
the reconstructed sea level near the coast and tide gauge data for 1927–2015
showed that the reconstruction underestimated observed coastal sea level
variability for timescales less than ∼5 years, but lower-frequency variability of coastal sea level was captured very well in both
amplitude and phase by the reconstruction. Comparison between the GS-SAB
proxy and the observed Florida Current transport for 1982–2015 also showed
significant correlations for oscillations with periods longer than
∼5 years. The study demonstrated that despite the coarse
horizontal resolution of the global reconstruction (1∘ × 1∘), long-term variations in regional dynamics can be captured
quite well, thus making the data useful for studies of long-term variability
in other regions as well.
Thick- and thin-skinned basin inversion in the Danish Central Graben, North Sea – the role of deep evaporites and basement kinematics
Authors: Hansen Torsten Hundebøl , Clausen Ole Rønø , Andresen Katrine Juul
Published: August 2020

Abstract. Using 3D reflection-seismic data constrained by wells, we address the kinematic connections between Permian Zechstein evaporites, basin-inversion structures in the sedimentary units above, and reactivated structures in the sub-salt basement in the Danish Central Graben. The Danish Central Graben is part of the failed North Sea rift system. Where present, mobile Zechstein evaporites have played a significant role in its structural development since the Triassic, while tectonic shortening caused mild inversion in the Late Cretaceous and Paleogene. Shortening was accommodated mainly by reverse reactivation of older normal faults (i.e. fault inversion) along with folding and uplift of their hangingwalls. Within the study area, rifting generated two major W-SW-dipping basement faults with several kilometres of normal offset. The larger Coffee Soil Fault delineate the eastern boundary of the rift basins. Within its hangingwall, a broad zone is characterised by inversion-related uplift and deformation. Along the fault, buttressed growth folds in the immediate hangingwall indicate thick-skinned inversion, i.e. coupled deformation between the basement and cover units. The opposite margin of the inverted zones follows the westwards pinch-out of the Zechstein salt. Here, thin-skinned folds and faults sole out into Zechstein units on the half-graben dip slopes. The most pronounced inversion occurred directly above and in extension of salt ridges and –rollers that localized shortening in the cover above. With no apparent links to underlying basement faults, we balance thin-skinned shortening to the sub-salt basement via a triangle-zone concept. This implies that thin Zechstein units on the half-graben dip slopes formed thrust detachments during inversion, and that basement shortening was mainly accommodated by reactivation of the major rift faults further east. Ductile deformation at seismic scales accounts for thin-skinned shortening of the cover units where such a detachment did not develop. We discuss the related mechanisms. The documented structural styles are similar to those found in other inverted basins in the region, and to those produced from physical-model experiments. Our results indicate that Zechstein units imposed a strong control on structural style and kinematics during basin inversion in large parts of the Danish Central Graben. We emphasize that even thin evaporite units may act as detachments during tectonic extension and contraction if favourably orientated. Salt ridges and diapiric structures can localise shortening and generate thin-skinned faults and folds in the cover above. In mildly inverted rifts, extensive mobile salt may mask the effects of basin inversion if shortening is accommodated by salt structures without the formation of clearly defined inversion structures at the surface or significant uplift.
Brief communication: Evaluating Antarctic precipitation in ERA5 and CMIP6 against CloudSat observations
Authors: Roussel Marie-Laure , Lemonnier Florentin , Genthon Christophe , Krinner Gerhard
Published: August 2020

Abstract. CMIP5, CMIP6, and ERA5 Antarctic precipitation is evaluated against CloudSat data. At continental and regional scales, ERA5 and the median CMIP models are biased high, with insignificant improvement from CMIP5 to CMIP6. However, there are fewer positive outliers in CMIP6. AMIP configurations perform better than the coupled ones, and, surprisingly, relative errors in areas of complex topography are higher (up to 50 %) in the five higher-resolution models. The seasonal cycle is reproduced well by the median of the CMIP models, but not by ERA5. Progress from CMIP5 to CMIP6 being limited, there is still room for improvement.
Fractional snow-covered area: Scale-independent peak of winter
parameterization

Published: August 2020

Abstract. The spatial distribution of snow in the mountains is significantly influenced through interactions of topography with wind, precipitation, shortwave and longwave radiation, and avalanches that may relocate the accumulated snow. One of the most crucial model parameters for various applications such as weather forecasts, climate predictions and in hydrological modeling is the fraction of the ground surface that is covered by snow, also called fractional snow-covered area (fSCA). While previous subgrid parameterizations for the spatial snow depth distribution and fSCA work well, performances were scale-dependent. Here, we were able to confirm a previously established empirical relationship of the peak of winter parameterization for the standard deviation of snow depth σ>sub>HS by evaluating it on 11 spatial snow depth data sets from 7 different geographic regions and snow climates with resolutions ranging from 0.1 m to 3 m. Enhanced performance (mean percentage errors (MPE) decreased by 25 %) across all spatial scales ≥ 200 m was achieved by recalibrating and introducing a scale-dependency in the dominant scaling variables. Scale-dependent MPEs vary between −7 % and 3 % for σ>sub>HS and between 0 % and 1 % for fSCA. A scale- as well as region-dependent evaluation revealed that for the majority of the regions the MPEs mostly lie between ±10 % for σ>sub>HS and between −1 % and 1.5 % for fSCA. This suggests that the new parameterizations perform similarly well in most geographical regions.

Eficiência sistêmica em empreendimentos econômicos solidários de reciclagem: construção e aplicação de indicadores multidimensionais
Authors: Maciel Joice Pinho , Ferrarini Adriane Vieira
Published: August 2020

A mensuração da eficiência de organizações econômicas se funda usualmente na racionalidade canônica da economia de mercado, para a qual a maximização de lucros é o propósito central, e o faturamento econômico, seu indicador de êxito. Empreendimentos do campo da economia solidária, cuja eficiência econômica é indissociável de outras dimensões, carecem de instrumentos para a captação desta multidimensionalidade. Este trabalho visa a analisar a aplicação de indicadores multidimensionais para a mensuração da eficiência de empreendimentos econômicos solidários (EES) de reciclagem através da apresentação do estudo de caso na Cooperativa UNIVALE, localizada no Estado do Rio Grande do Sul (Brasil). Para tanto, foi desenvolvido o Índice de Eficiência Multidimensional de Cooperativas de Reciclagem (IEMCR) através de pesquisa exploratória, de revisão teórica e análise de instrumentos (Ferrarini, 2008; Kraychete, 2012; Gaiger & Grupo Ecosol, 2014). O IEMCR foi elaborado a partir de uma visão sistêmica da realidade e mediante a aglutinação de indicadores simples referidos às dimensões econômica, social, política, ambiental e humana. Os resultados da aplicação do IEMRC evidenciaram que os EES pesquisados são eficientes do ponto de vista multidimensional, pois compatibilizam a eficiência econômica com o bem-estar e cidadania dos seus membros; constituem importantes espaços de luta política; geram impacto social e ambiental positivo e contribuem para formas de desenvolvimento mais sustentável e inclusivo. A diversidade de indicadores também oportunizou a identificação de fragilidades e a elaboração de uma pauta propositiva para a melhoria da eficiência multidimensional dos EES, podendo ser um instrumento aplicável tanto a processos de pesquisa quanto de diagnóstico em atividades de assessoria a organizações econômicas que privilegiam o impacto social e ambiental.

Authors: Saufie Syafiqah , Estim Abentin , Shaleh Sitti R. M. , Mustafa Saleem
Published: August 2020

Aim of study: To evaluate the biomass production of green bean (Phaseolus vulgaris) in a media-filled aquaponics system together with Genetically Improved Farmed Tilapia, GIFT (Oreochromis niloticus).Area of study: Kota Kinabalu, Sabah (Malaysia).Material and methods: The experiment involved modulating and optimizing the density of extractive species (plants) in the hydroponic tank (55 cm × 35 cm). Five treatments were carried out: T0 (control-without plant), T2 (2 plants), T4 (4 plants), T8 (8 plants), T12 (12 plants) where the stocking density of GIFT was 30 tails (identical in all the treatments). Water volume in each treatment was 800 L and the experimental set up was closed recirculating type. The trials were carried out over a period of 90 days.Main results: Growth of the GIFT was not affected by the presence of green bean or by manipulation of the stocking density. Treatment T4 yielded significantly higher biomass production of green beans (1556.4 ± 88.9 g), compared to T2 (1083.6 ± 86.9 g), T8 (404.6 ± 47.9 g), and T12 (401.8 ± 98.1 g). There were noticeable fluctuations in the concentrations of NH3-N (ammonia), NO2-N (nitrite), NO3-N (nitrate) and PO4-P (phosphate) over the experimental period that indicated the process of nitrification and absorption of nutrients.Research highlights: The nitrogenous waste produced by the fish supported the biomass of the green beans in the aquaponics system and the waste uptake of this extractive species is effective enough for reuse of the water for rearing of GIFT.
Socioeconomic Status Is Associated With the Risk of Girdlestone Resection Arthroplasty After Periprosthetic Infection of the Hip

Published: August 2020

Introduction:

Girdlestone resection arthroplasty (GRA) is a radical but sometimes necessary treatment of periprosthetic joint infection (PJI) of the hip. The purpose of this of this study was to identify the independent risk factors for GRA after PJI of the hip.

Methods:

This is a retrospective, cross-sectional analysis of the National (Nationwide) Inpatient Sample from 2010 to 2014. The International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) was used to identify 27,404 patients with PJI of the hip, including 889 patients who underwent GRA (ICD-9-CM 80.05). A multivariate model was created to examine the association between GRA and patient characteristics such as age, sex, race, primary payer, median household income, and location and teaching status of the hospital where the procedure was performed. Furthermore, the model controlled for patient comorbidities, including diabetes, anemias, hypertension, congestive heart failure, chronic pulmonary disease, peripheral vascular disease, and drug abuse.

Results:

The strongest independent risk factor for GRA was Medicare insurance (odds ratio [OR], 1.859, 95% confidence interval [CI], 1.500 to 2.304). Medicaid insurance was also associated with GRA (OR, 1.662, CI, 1.243 to 2.223). Compared with the wealthiest quartile for household income, patients in the poorest quartile (OR, 1.299, CI, 1.046 to 1.614) and second poorest quartile (OR, 1.269, CI, 1.027 to 1.567) were significantly more likely to have a GRA. Furthermore, patients older than 80 years old were at a higher risk of GRA than all other age groups (P < 0.05). No statistical differences were seen regarding patient race or sex.

Conclusions:

This study demonstrates that poorer patients, patients with government health insurance plans, and elderly patients are each at independently heightened risk of undergoing a GRA for the treatment of PJI of the hip.

Filial Nationalism in Global Competition: The 2001 Reform of Mandarin Textbooks

In the early 2000s the Chinese government initiated a profound shift in how it sought to represent China at home and abroad. Whereas many scholars and China watchers argue that a newly assertive China emerged in the wake of the 2008 economic crisis, I argue that this shift took place
in the curriculum reforms nearly a decade earlier. An analysis of the evolution of textbooks used for primary Mandarin instruction shows that, starting in 2001, textbooks were developed to inculcate a perennial bond between an increasingly globalized population and its motherland. Specifically,
I show how the emergence of filial nationalism was crafted in Mandarin-language textbooks, laying the groundwork for a new generation of Chinese youth to simultaneously feel pride for and loyalty to the motherland while preparing them for integration into a globalized world.

Google Android: mag men een gegeven paard toch in de bek kijken?

In het Google Android-besluit heeft de Europese Commissie aan Google een recordboete opgelegd wegens misbruik van een economische machtspositie in de zin van artikel 102 VWEU. In het besluit staat Android, het besturingssysteem van Google voor smartphones en tablets, centraal. Google biedt dit aan via een open source-model. Het besluit stelt een machtspositie van Google vast op verschillende digitale markten: (1) de markt voor licenseerbare besturingssystemen voor slimme mobiele apparaten, (2) de markt voor Android appstores en (3) de markt voor algemene zoekdiensten op het internet (Google Search). Volgens de Commissie heeft Google met verschillende gedragingen, waaronder exclusiviteitsbetalingen en koppelverkoop, haar positie op laatstgenoemde markt, waarop zij inkomsten genereert via online advertenties, willen beschermen. De Commissie kwalificeert deze gedragingen als misbruik in de zin van artikel 102 VWEU. De auteurs analyseren het besluit en de inzet van het mededingingsrechtelijke instrument misbruik van een economische machtspositie in deze complexe digitale omgeving. Daarbij gaan zij in het bijzonder ook in op het bijzondere verdienmodel van Google ten aanzien van Android, waarbij innovatieve technologie kosteloos ter beschikking wordt gesteld in ruil voor restricties die erop zijn gericht de Googlediensten die advertentie-inkomsten genereren een zo groot mogelijk bereik te garanderen.

De zaak TenderNed: de reikwijdte van overheidsgezag en het staatssteunrechtelijke economische-activiteitenbegrip

In dit artikel wordt het arrest TenderNed besproken, waarin het Hof van Justitie oordeelde dat het aanbieden van applicaties ter ondersteuning van aanbestedende diensten bij de uitvoering van hun aanbestedingsactiviteiten niet onder de staatssteunregels valt. Met het aanbieden van TenderNed wordt namelijk uitvoering gegeven aan overheidsgezag en daarom is geen sprake van een economische activiteit waarop de staatssteunregels van toepassing zijn. In dit artikel onderzoekt de auteur de in deze arresten gegeven interpretatie van het begrip ‘overheidsgezag’.

The impact of COVID-19 on tourism in Cracow in the eyes of tourism entrepreneurs
Authors: Walas Bartłomiej , Kruczek Zygmunt
Published: August 2020

The purpose of the study was to collect opinions of Krakow’s tourism entrepreneurs about the impact of the pandemic on their activities and their expectations concerning tools of marketing communication that could facilitate recovery. The respondents were asked to assess the drop in sales of tourism services, their opinions concerning the prospect of a tourist traffic recovery, possible measures that could facilitate the recovery and what they expected the local government to do in this respect. In recent years Kraków has become one of Poland’s most recognisable destinations, benefiting from increasing revenues generated by a systematically growing number of visitors. This growth has even prompted concerns about overtourism in Kraków. The outbreak of the COVID-19 pandemic has dramatically affected the entire supply chain in the tourism industry, leaving the city empty of tourists and causing a financial breakdown for many companies. In order to diagnose the scale of the crisis triggered by the pandemic, the authors conducted a CAWI survey of Kraków based tourism entrepreneurs in the middle of March. The development of the epidemic and steps taken to protect the tourism sector from mid-March to the end of June 2020 were used to validate views formulated by the respondent. The results of the survey reveal the level of economic losses anticipated by tourism entrepreneurs and their predicted occurrence over time, opinions about the likely sequence in which particular tourism products in Kraków are going to recover, as well as expectations concerning the tools of marketing communication that could facilitate the recovery.
Vozes ininteligíveis e silêncios orais: epistemologias do Sul em Rap global
Authors: Medeiros Jefferson Ubiratan de Araújo
Published: August 2020

Rap global (OESTE [SANTOS] 2010) é um livro de poemas publicado por Boaventura de Sousa Santos sob o pseudônimo de Queni N. S. L. Oeste. O meu intento nesse artigo é compreender, por meio da leitura e fruição desse objeto literário, como se dá o seu processo de instanciação e encenação enunciativa. Defendo que tal processo, na obra em foco, engendra a produção de geografias discursivas. A partir do exame de alguns trechos do rapoema de Santos pretendo evidenciar a relação de tais geografias com os conceitos cunhados pelo sociólogo, a saber, a “tradução intercultural” e a “ecologia de saberes”, ambos integrados às “epistemologias do sul”, do sociólogo português.

Palavras-chave: Rap global. Boaventura de Sousa Santos. Encenação enunciativa. Geografias discursivas. Epistemologias do Sul.
Interseções: o darwinismo social em Rubens Figueiredo e o humanitismo machadiano
Authors: Paiva Rejane Fernández Loureiro de
Published: August 2020

Este artigo trata da interlocução que o romance Passageiro do fim do dia (2010), de Rubens Figueiredo, estabelece com o Humanitismo, a filosofia cínica proposta por Quincas Borba, notória personagem de Machado de Assis. Apesar da distância de, aproximadamente 150 anos, que separa os dois autores, entendemos que o darwinismo social, sobre o qual se detém Rubens Figueiredo, e o humanitismo machadiano, conformam-se como estratégias textuais similares. Ambos os autores interpelam correntes filosóficas positivistas, em voga na época do “bruxo do Cosme Velho” e ainda vigentes, mormente no que se aplica ao postulado de Charles Darwin aplicado ao mundo social, nos anos atuais. Assim, ambos tematizam as relações de força, em que prevalecem o ganho, o prestígio pessoal e a soberania do interesse. Enquanto Machado de Assis se centra nos jogos de salão da Corte, Rubens Figueiredo privilegia a arraia miúda, a classe trabalhadora e as interdições que lhes são impostas. Encontramos, tanto na narrativa de Rubens Figueiredo, quanto na obra de Machado de Assis, uma busca por uma “teoria de tudo”, “uma doutrina que, segundo diziam, abria mil caminhos, explicava muita coisa e de uma vez por todas”, no universo ficcional do primeiro, e,  na linguagem de Machado de Assis, “a mais abrangente das filosofias, a ponto de vir a ser mesmo uma nova religião”, o “remate das coisas”. Todos esses elementos conformar-se-iam como a busca impossível por uma resposta radical, totalizante, que aliviasse os males humanos, encenados em suas narrativas.
Aulas de Matemática nos contextos da Educação no Campo
Authors: Lima Samya de Oliveira , Menezes Marcus Bessa de
Published: August 2020

Neste trabalho, objetivou-se analisar o ensino de Matemática na modalidade da Educação do Campo. Conforme definido pela legislação brasileira, a Educação do Campo deve ser específica e emancipatória mediante as expressões sociais, culturais e políticas de cada sujeito. Discussões recentes na área da Educação do Campo apontam a importância de fomentar, nos processos de ensino e aprendizagem, o protagonismo dos educandos por meio de situações didáticas que incluam as dimensões sociais, culturais e políticas existentes nos diferentes contextos desses sujeitos. A abordagem metodológica se configurou em um estudo de caso com característica etnográfico. É pautada numa abordagem qualitativa, na perspectiva da Etnomatemática. A pesquisa foi real izada na Universidade Regional do Cariri – Urca, no Estado do Ceará, com estudantes do curso, sendo estruturada na aplicação do questionário. Espera-se que estes estudos sobre ensinar Matemática nos cursos de Licenciatura do Campo possam contribuir para uma reflexão acerca do pr ocesso de formação desses educandos. A valorização das vivências, das experiências cotidianas e dos sonhos, reconhecendo o sujeito em seu espaço, em suas raízes, sua cultura, seus conhecime ntos, seus desejos, para dar “voz” e “vez” e resgatar nos discentes o seu direito à cidadania, com a finalidade de termos uma sociedade com mais oportunidades e menos desigualdades.
