Published: April 2019

Purpose:

A driving factor in pancreatic ductal adenocarcinoma (PDAC) treatment resistance is the tumor microenvironment, which is highly immunosuppressive. One potent immunologic adjuvant is radiotherapy. Radiation, however, has also been shown to induce immunosuppressive factors, which can contribute to tumor progression and formation of fibrotic tumor stroma. To capitalize on the immunogenic effects of radiation and obtain a durable tumor response, radiation must be rationally combined with targeted therapies to mitigate the influx of immunosuppressive cells and fibrosis. One such target is ephrinB2, which is overexpressed in PDAC and correlates negatively with prognosis.

Experimental Design: On the basis of previous studies of ephrinB2 ligand-EphB4 receptor signaling, we hypothesized that inhibition of ephrinB2-EphB4 combined with radiation can regulate the microenvironment response postradiation, leading to increased tumor control in PDAC. This hypothesis was explored using both cell lines and in vivo human and mouse tumor models.

Results:

Our data show this treatment regimen significantly reduces regulatory T-cell, macrophage, and neutrophil infiltration and stromal fibrosis, enhances effector T-cell activation, and decreases tumor growth. Furthermore, our data show that depletion of regulatory T cells in combination with radiation reduces tumor growth and fibrosis.

Conclusions:

These are the first findings to suggest that in PDAC, ephrinB2–EphB4 interaction has a profibrotic, protumorigenic role, presenting a novel and promising therapeutic target.
Effect of Progression in Malnutrition and Inflammatory Conditions on Adverse Events and Mortality in Patients on Maintenance Hemodialysis
Authors: Toyoda Kazuhiro , Kuragano Takahiro , Kawada Hiroaki , Taniguchi Tomo , Nakanishi Takeshi
Published: April 2019

Background/Aim: In maintenance hemodialysis (MHD), protein-energy malnutrition and chronic inflammation can be critical and are two of the main causes of mortality. Method: We compared the change in nutrition and inflammatory conditions between younger and older MHD patients during a 2-year period. Furthermore, using Kaplan-Meier analysis, we evaluated the correlations between changes in each parameter and any adverse events. Result: During the observational period, body mass index (BMI) and serum albumin levels decreased significantly in older patients. In Kaplan-Meier analysis, patients who showed a decline in BMI had an associated elevated risk for cerebro-cardiovascular disease and hospitalization. Moreover, patients who showed a decline in albumin also had an associated higher risk for infectious disease and hospitalization. Conclusion: This study revealed that the downward trend in nutritional status was prominent in elderly patients. Furthermore, changes in nutritional and inflammatory conditions during MHD were associated with adverse events in MHD patients.

Published: April 2019

Background/Aims: There is lack of definitive evidence about the association between erythropoiesis-stimulating agent (ESA) responsiveness in the pre-dialysis phase and mortality. Therefore, we conducted a hospital-based, retrospective, cohort study to assess the predictive value of ESA response for prognosis in incident hemodialysis patients. Methods: A total of 108 patients without preexisting cardiovascular disease who had been started on maintenance hemodialysis were studied. ESA responsiveness just before starting dialysis was estimated using an erythropoietin resistance index (ERI). The endpoint was defined as all-cause death. Results: During a mean follow-up period of 3.1 ± 1.6 years, 18 (17%) patients died. Overall, the multivariate Cox regression analysis revealed that the log-transformed ERI remained an independent predictor of all-cause death after adjustment using a propensity score (hazard ratio 2.25, 95% CI 1.25–4.06). Conclusions: Among incident hemodialysis patients, hyporesponsiveness to ESA may be associated with mortality.

Published: April 2019

Background: A novel class of membranes, medium cut-off (MCO) membranes, has recently been designed to achieve interesting removal capacities for middle and large middle molecules in hemodialysis (HD) treatments. The few studies published to date have reported contradictory results regarding middle-sized molecules when comparing MCO dialyzers versus dialyzers used in online hemodiafiltration (OL-HDF). Methods: A prospective, single-center study was carried out in 22 patients. Each patient underwent 9 dialysis sessions with routine dialysis parameters, one with an MCO dialyzer in HD and the other 8 with different dialyzers in OL-HDF. The removal ratio (RR) of urea, creatinine, β2-microglobulin, myoglobin, prolactin, α1-microglobulin, α1-acid glycoprotein, and albumin was intraindividually compared. Albumin loss in dialysate was measured. We propose a global removal score ([ureaRR + β2-microglobulinRR + myoglobinRR + prolactinRR + α1-microglobulinRR + α1-acid glycoproteinRR]/6 – albuminRR) as a new tool for measuring dialyzer effectiveness. Results: No significant differences in the RRs of small and middle molecular range molecules were observed between the MCO vs. OL-HDF dialyzers (range 60–80%). Lower RRs were found for α1-microglobulin and α1-acid glycoprotein without significant differences. The albumin RR was < 11% and dialysate albumin loss was < 3.5 g in all situations without significant differences. The global removal score was 54.9 ± 4.8% with the MCO dialyzer without significant differences. Conclusions: Removal of a wide range of molecular weights, calculated with the proposed global removal score, was almost equal with the MCO dialyzer in HD treatment compared with 8 high-flux dialyzers in high-volume OL-HDF without relevant changes in albumin loss. The global removal score could be a new tool to evaluate the effectiveness of dialyzers and/or different treatment modalities.

Published: April 2019

The taxonomy of the T. bessonii, T. bonibony, T. dysalum, T. marginatum, T. tsingy, and T. weitzeckeri species groups isrevised. A total of 33 species is treated, of which 27 are newly described and one is raised to species status. The T.weitzeckeri group contains the single species T. humbloti Forel, which is of Afrotropical origin and the only representativeof the group in the Malagasy region. The species T. bessonii Forel, T. dysalum Bolton, T. marginatum Forel, and T. stein-heili Forel, which were originally members of the T. weitzeckeri group, are now placed in other groups. Tetramorium bes-sonii is the core species of the T. bessonii group, which also contains the four newly described species T. artemis sp. n., T.malagasy sp. n., T. ryanphelanae sp. n., T. wardi sp. n., and T. orientale Forel stat. n., which was a junior synonym of T.bessonii but is now raised to species rank. The T. dysalum group is a moderately-sized group with ten species, of whichonly T. dysalum and T. steinheili were previously known; the other eight species are all newly described. The newly described species in this group are: T. ambatovy sp. n., T. macki sp. n., T. mallenseana sp. n., T. orc sp. n., T. robitika sp. n.,T. sargina sp. n., T. yammer sp. n., and T. vohitra sp. n. A lectotype and several paralectotypes of T. steinheili are desig-nated. Tetramorium marginatum is the central species of the T. marginatum group, which also includes the five newly de-scribed species T. valky sp. n., T. hector sp. n., T. norvigi sp. n., T. shamshir sp. n., and T. silvicola sp. n. The T. bonibonyand T. tsingy groups represent completely new groups that consist entirely of previously unknown, undescribed species.The first group holds the new species T. bonibony sp. n., T. kali sp. n., T. sada sp. n., T. nosybe sp. n., T. olana sp. n., T.popell sp. n., and T. trafo sp. n. and T. vony sp. n. The last group, the T. tsingy group, only contains the two species T. tyrionsp. n. and T. tsingy sp. n., both among the rarest Tetramorium species in Madagascar. All groups are fully revised withillustrated species-level identification keys, and all species are described/re-described and illustrated with high qualitymontage images. In addition, the current status of the Malagasy Tetramorium species groups is discussed and further modifications are proposed.

Authors: LEE JIMIN , CHANG CHEON YOUNG
Published: April 2019

Three new gastrotrich species of the genus Tetranchyroderma are described sublittoral sandy bottoms of the Yellow Sea and Jeju Island in South Korea. Tetranchyroderma aethesbregmum sp. nov., which has a dorsal cuticular armature with pentancres only, is characterized by the peculiar shape of the head with a median trapezoidal lobe flanking three pairs of papillae. Tetranchyroderma megabitubulatum sp. nov. is clearly differentiated from other pentancrous species by the character combination of three pairs of cephalic tentacles, a pair of long dorsolateral adhesive tubes, and paired ‘foot’ ventral adhesive tubes. Tetranchyroderma insolitum sp. nov. is the only species possessing cuticular armature with tetrancres and triancres mixed, and also characteristic in having an earlobeprotrusion at the posterolateral corners of head.

Amynthas gageodo Blakemore, sp. nov. is described from small Gageo-do Island, offshore to the southwest of the Korean Peninsula in the Yellow Sea. It is an octothecal species (four pairs of spermathecae) comparable to Japanese Amynthas carnosus (Goto & Hatai, 1899) (synonyms: Korean kyamikia Kobayashi, 1934, monstrifera Kobayashi, 1936, sangyeoli Hong & James, 2001, youngtai Hong & James, 2001, kimhaeiensis Hong & James, 2001, sinsiensis Hong & James, 2001, baemsagolensis Hong & James, 2001, Taiwanese monsoonus James et al., 2005) and to Chinese A. pingi (Stephenson, 1925) (synonym: fornicata Gates, 1935). Species associations in its forest litter habitat on the remote island included terrestrial leeches, planarian flatworm predators and other worms. MtDNA COI barcodes indisputably identify types of A. gageodo as a new model for future Korean earthworm species characterizations.

Published: April 2019

Two new cyclopoid species belonging to the genus Halicyclops Norman, 1903 are described from brackish waters in South Korea: H. lanceolatus sp. nov. and H. pumilus sp. nov. Halicyclops lanceolatus was collected from two river mouths, both connected to caves. It belongs to the thermophilus group in showing 3,4,4,3 spine formula on legs 1-4 and lateral process on the genital double-somite. Among the members of the species group, it is closely allied with H. thermophilus Kiefer, 1929 and H. uncus Ueda and Nagai, 2009. However, it differs from them by a stout, lanceolate inner apical spine on leg 5 exopod, very short lateral process of the genital double-somite, short caudal rami, and shorter inner apical spine on the third endopodal segment of leg 4. Halicyclops pumilus was collected from interstitial waters of estuarine sandy beaches, and it is characteristic in having a single inner seta on the second endopodal segments of legs 2-3, and quadrate shape of leg 5 exopod with stumpy spines.

CATALOGUE OF THE NOMINAL TAXA OF MESOAMERICAN PACHYCHILIDAE (MOLLUSCA: CAENOGASTROPODA)
Authors: GOMEZ-BERNING MARIA , KÖHLER FRANK , GLAUBRECHT MATTHIAS
Published: April 2019

The caenogastropod family Pachychilidae Troschel, 1858 is a monophyletic group of freshwater snails that is distributedin the tropical regions of the world, where they exhibit high levels of endemism at the species and generic levels. Thereare many uncertainties regarding generic affiliation and species names in the Mesoamerican Pachychilidae owing to theirrelatively variable shells, the lack of distinctive anatomical features and the intricate taxonomic histories. In an attempt toconsolidate the knowledge of this taxon in the Neotropics, we provide here a catalogue of all available names of theMesoamerican pachychilid fauna, laying the foundation for future taxonomic revisions. Primary types were located for 56species-group taxa, and lectotypes for 22 nomina were designated. 102 nominal taxa of Mesoamerican pachychilids wereoriginally described. We consider that six of these taxa belong to other cerithioidean families. Two nomina are consideredto be unnecessary replacement names (Melania renovata Brot, 1862; Pachychilus tristrami Crosse & Fischer, 1892). Twotaxa are South American species that were incorrectly associated with Mesoamerican taxa (Pachychilus laevissimus sensuReeve, 1860; Melania laevissima var. decollata Brot, 1875). The exact type locality of Pachycheilus dalli Pilsbry, 1896and Melania mexicana were identified, and we accept Pachychilus hinkleyi (Marshall, 1920) as replacement name of the invalid Sphaeromelania hinkleyi Marshall, 1920.

New sponge species from hydrothermal vent and cold seep sites off New Zealand
Authors: KELLY MICHELLE , ROWDEN ASHLEY A.
Published: April 2019

Three new sponge species in the demosponge families Chalinidae Gray and Suberitidae Schmidt are described from the Calypso hydrothermal vent field in the Bay of Plenty, and one species from seep sites along the Hikurangi Margin, to the east of the North Island, New Zealand. The Calypso hydrothermal vent field is dominated by the chalinid sponge Haliclona (Soestella) battershilli sp. nov., a large, cream-coloured, finely branched species, and the less common H. (Halichoclona) sonnae sp. nov., an encrusting, translucent white, cushion-shaped species. The third species, the suberitid sponge Protosuberites novaezelandiae sp. nov., forms encrustations with digitate projections. Haliclona (Halichoclona) sonnae sp. nov. and Protosuberites novaezelandiae sp. nov. represent new subgenus and genus records, respectively, for New Zealand waters. The methanotrophic suberitid sponge, Pseudosuberites thurberi sp. nov., is found at many of the cold seep sites on the Hikurangi Margin where it forms extensive, encrusting to digitate mats. The description of these species provides a basis for the future study of the ecology of sponges that are apparently endemic to vent and seep habitats off New Zealand.
Experimental investigation and simulation of the performance of a pre-twister based on the jet vortex field used for the ring spinning frame
Authors: He Shanshan , Xue Wenliang , Chen Ge , Cheng Longdi
Published: April 2019

The ring spun technique has always held a domain position in yarn spinning, thanks to its simple and robust structure, ease of maintenance and good quality in the product. A pre-twist device is arranged between the front rollers and an additional pair of rollers, which are named the holding rollers. In this paper, the simulation and characterization of the airflow field, as well as the fiber movement and deformation, in this pre-twisting zone are carried out by computational fluid dynamics software. The airflow simulation results show that there is a core region formed around the roving in the pre-twister, with a radius of about 1.55 mm. In the core region, the tangential speed is the major velocity component ranging from 0–70 m/s and the axial velocity is the minor one ranging from –13 to about 4.1 m/s. The air velocity inside the whole tube is from 462 to 0 m/s. The two-way coupled simulation verified that the airflow can drive the fibers to wind on the roving. The experiments on the surface morphology verified the wrapping phenomena in the simulation. Due to the employment of the pre-twister, the yarn properties got a little worse, with declines of 6% in strength and 10% in evenness, respectively. Comparing with the Uster Statistics for 2018, these declines are acceptable. Furthermore, it is shown that with this kind of pre-twister, the spinning speed can increase by 27.13% with an acceptable decrease in cotton yarn property (decreases of 13% in strength and 8% in evenness).

Although engineering is by nature an applied and interdisciplinary field, courses in engineering can lead even the best students to develop knowledge that is disconnected from other related fields and from conditions of application. This paper describes an innovative undergraduate course that integrated the theory of shock waves, computational modeling, experimental testing, and science of sustainable manufacturing. The course supported better visualization of mechanical and aerospace engineering phenomena, such as shock waves in supersonic gas flows, by utilizing the hydraulic analogy of shallow water and a simple water table. Airfoil design and manufacture were integrated through aerospace and manufacturing theory and application. For the first course offering, student learning was assessed with regard to their views of engineering, learning experience, and transfer of learning. The course proved to increase self-efficacy as engineers, as well as their self-reported confidence in working comfortably on multi-disciplinary teams. Furthermore, scenario-based assessments confirmed that the students were able to integrate aerospace and manufacturing theory and application within new scenarios.

Increasingly, metropolitan areas are prioritizing growth in the share of trips taken by bicycle to improve health outcomes, transportation affordability, and environmental performance of the transport system. Evidence is building that network quality is an important determinant in bicycle commuting and route choice. One prominent metric of facility attractiveness is bicycle level of traffic stress (LTS). In tandem, OpenStreetMap (OSM) is becoming an important source of network data for routing and for generating measures of multimodal accessibility. Although there are studies that examine the completeness of OSM tags and utilize OSM data to compute LTS on networks, none of them examine the accuracy of these analyses. The goal of this paper is to evaluate the accuracy of OSM-derived LTS predictions and offer quality assurance strategies to reduce inaccurate predictions. This study compares OSM-derived LTS predictions with ground-truthed LTS scores created by Montgomery County. It finds that OSM-derived LTS networks provide comparable results to the ground-truthed data. The OSM-derived LTS scores correctly identified 89.9% of the length of the network as either high (LTS 3 or 4) or low stress (LTS 1 or 2). However, this study demonstrates there is a higher potential for error within certain street typologies and urban contexts, and that low-stress accessibility calculations can be very sensitive to even a small number of incorrectly classified segments. Finally, practices to improve the quality of OSM-derived LTS predictions and low-stress accessibility calculations are suggested.
Paris and Nice terrorist attacks: Exploring Twitter and web archives

Published: April 2019

The attacks suffered by France in January and November 2015, and then in the course of 2016, especially the Nice attack, provoked intense online activity both during the events and in the months that followed. The digital traces left by this reactivity and reactions to events gave rise, from the very first days and even hours after the attacks, to a ‘real-time’ institutional archiving by the National Library of France ( Bibliothèque nationale de France, BnF) and the National Audio-visual Institute ( Institut national de l’audiovisuel, Ina). The results amount to millions of archived tweets and URLs. This article seeks to highlight some of the most significant issues raised by these relatively unprecedented corpora, from collection to exploitation, from online stream of data to its mediation and re-composition. Indeed, web archiving practices in times of emergency and crises are significant, almost emblematic, loci to explore the human and technical agencies, and the complex temporalities, of ‘born-digital’ heritage. The cases examined here emphasize the way these ‘emergency collections’ challenge the perimeters and the very nature of web archives as part of our digital and societal heritage, and the guiding visions of its governance and mission. Finally, the present analysis underlines the need for a careful contextualization of the design process – both of original web pages or tweets and of their archived images – and of the tools deployed to collect, retrieve and analyse them.
Crisis as Opportunity: Nixon’s Announcement to Close the Gold Window
Authors: Zoeller Christoffer J. P. , Bandelj Nina
Published: April 2019

The authors reexamine the announcement of the August 1971 decision to suspend convertibility of U.S. dollars to gold, or closing of the gold window, which ended the Bretton Woods system and ushered in the neoliberal era. Existing accounts identify critical pressure on the U.S. gold supply after May 1971 international currency disruptions as a tipping point for this policy. In contrast, using new archival evidence, the authors reveal that Nixon strategically framed May 1971 events as an urgent economic “crisis,” deploying “crisis” as a justification for closing the gold window. Nixon seized crisis opportunism to announce a policy decided upon significantly before May 1971, to privilege U.S. interests in the international arena and to assuage his reelection concerns, before potential backlash by the International Monetary Fund members and the U.S. Congress. The authors draw lessons from this historical case for contemporary events and for examining economic crises as objects of inquiry in their own right.
Association of ACE gene polymorphism with cardiovascular determinants of trained and untrained Iranian men
Authors: Falahati Akram , Arazi Hamid
Published: April 2019

Background

The insertion (I) rather than deletion (D) of human angiotensin converting enzyme gene (ACE) is associated with lower circulating ACE activity and with endurance performance among Caucasians. The frequency of the ACE gene I/D allele in Iranian sample seems to be more similar to the Caucasians. To assess the possible relationship between I/D polymorphism of ACE gene with athletic status and selected cardiovascular indices and VO2max in an Iranian population, DNA samples were obtained from 57 trained and untrained men, with soccer as their main training modality. Genotyping for ACE I/D polymorphism was performed using polymerase chain reaction. VO2max was determined by an incremental test to volitional exhaustion on a motorized treadmill.

Results

I/D genotype was neither associated with elite athlete status nor with VO2max, resting heart rate, systolic and diastolic blood pressure. There was no interaction effect of training statue x ACE genotype for each of the examined indices.

Conclusions

ACE gene variation was not a determinant of cardiovascular function and VO2max in either trained or untrained Iranian participating in soccer. The absence of an association between either I/D genotype and elite Iranian athlete status and better cardiovascular function also suggests that the ACE gene does not contribute significantly to the phenomenal success of Iranian soccer players.

The Chalk Group forms important hydrocarbon reservoirs offshore and water aquifers onshore Denmark. Within a day of fieldwork, a 450 m long reflection seismic profile was acquired onshore in an area in southeast Denmark, where the Chalk Group extends almost to the surface and is approximately 900 m thick. The main objective of the study was to image the complete Chalk Group in high resolution and to study the origin of reflectivity within the different chalk units. A 45 kg accelerated weight-drop source, in combination with dense receiver spacing using microelectromechanical sensors mounted on a streamer and 48 planted geophones, was used for data acquisition. The profile runs subparallel to the cliffs of Stevns, and the recorded signal reaches the base of the Chalk Group at approximately 600 ms. The fully cored 443 m-deep Stevns-1 borehole, which is located at the recorded seismic line, provides excellent control on lithologic and facies changes. Comparison with the borehole data demonstrates that our seismic data set provides a high-resolution image of the internal layering of the Chalk Group. We find that the internal reflection coefficients of the Chalk Group are, in general, small based on wireline-log data. However, the reflected amplitudes are just big enough to be recorded with the receiver setup used, even from the pure chalk beds of the Chalk Group. The reflectivity seen on the high-resolution seismic profile is influenced by occurrences of clay-enriched chalk layers. Flint bands consisting of numerous flint nodules are a characteristic of the uppermost part of the Chalk Group at Stevns. The flint nodules appear to produce significant scattering of the seismic signals, and flint-rich layers appear with diffuse internal reflectivity characteristics. Outcrop-scale mound structures in Danian and Upper Cretaceous outcrops are for the first time seismically resolved.

Objective:

Despite having a detailed MRI-safety questionnaire check at the point of referral, we have encountered a significant number of near-misses with patients being identified with MRI-Unsafe devices at the time of appointments, making this an important safety hazard.

Methods and materials:

A two-part survey was performed to assess referrer compliance of asking MRI-questionnaires. 120 outpatients across 3 MRI sites were interviewed at the time of appointment to confirm whether their referrers completed the MRI questionnaires with them at the time of referral. Location: Department of Radiology, Ninewells Hospital, Perth Royal Infirmary and Stracathro Hospital in Scotland.

Results:

Only 50–55 % of patients confirmed that they were asked about presence of a pacemaker at the point of referral. Less than 50 % of patients reported being asked about other potential hazards. Suggested strategies for change: (1) Risk Alert—Sent to all MRI referrers in the organization. ( 2) Changes to MRI Safety Questionnaire. (3) Feedback mechanism to referrers—NHS trust website publications on number of recorded near-misses and wasted appointments due to MRI-safety issues. (4) Compulsory education/training of future referrers (junior doctors/allied health professionals). (5) Education of patients/public on MRI safety—Displaying patient information leaflets/posters in waiting areas of the hospital. Key measures for improvement: (1) Reduction in number of recorded near-misses. (2) System improvements, referrer and patient education, reduction of wasted MRI appointments and improvement of waiting-times for MRI appointments Effects of survey and conclusions: The survey highlights the possibility of inadequate referrer attention, and poor patient communication about MRI safety questionnaire with regards to potential hazards of MRI examination in presence of undeclared implants. It initiated several interventions resulting in improved patient safety, with no events in next 12 months, whilst promoting public and referrer’s understanding of potential MRI safety issues. Such actions are recommended for all NHS centres across UK since there are significant similarities in functioning across UK.

Authors: Kelly Vera Lúcia de Aguiar , Fonseca Ana Carolina Pimentel Duarte da , Sauerbronn Fernanda Filgueiras
Published: April 2019

O presente estudo propõe-se a compreender como o programa de microcrédito implementado na Cidade de Deus está contribuindo para a diminuição da pobreza no segmento da população excluída pelo mercado bancário tradicional. Para tal, destacam-se dois aspectos: um, de cunho social – a busca  do microcrédito pela população pobre -- e outro, de cunho econômico – que aborda a autossustentabilidade financeira do programa. Foi empreendido um estudo qualitativo com pesquisa de campo e entrevistas semiestruturadas com microempreendedores locais, representantes de instituições financeiras e demais entidades que proporcionam crédito na comunidade. Os resultados obtidos demonstram que ainda existem entraves que dificultam o acesso dos mais pobres aos recursos do microcrédito e que a sustentabilidade financeira das instituições tem norteado as decisões quanto aos beneficiários destes recursos.

Published: April 2019

O presente estudo tem como objetivo identificar as principais barreiras inibidoras do desempenho em cooperativas da agricultura familiar e compreender como essas barreiras podem tornar-se entraves para o acesso e a execução de políticas públicas. Foi adotado o método de estudo de caso comparativo em duas cooperativas, Cooperativa dos Produtores Rurais das Matas de Minas (COOPRAMM) e Cooperativa dos Produtores da Agricultura Familiar Solidária (COOPAF), tendo como objeto de análise entrevistas realizadas com membros do conselho de administração. Foi possível constatar algumas barreiras em comum entre as cooperativas, como restrições de recursos e baixa participação dos associados. Os elementos que as particularizam – associados à trajetória histórica, ao gerenciamento e à assistência técnica – se mostraram como barreiras inibidoras para o desempenho e também para o acesso ao mercado institucional na COOPRAMM. A contribuição que se busca é tornar este estudo útil para gestores públicos, mediante o diagnóstico das principais barreiras que constituem obstáculos para o desempenho e para o acesso e a execução de políticas públicas, o que pode contribuir na proposição de iniciativas governamentais para apoiar o fortalecimento dessas organizações como entidades articuladoras do mercado institucional.

Published: April 2019

Russian education is becoming increasingly competitive on the world stage. This is largely due to the fact that the authorities and education management of the Russian Federation, guided by the Federal law “on strategic planning in the Russian Federation” of 28.06.14. № 172-FZ conduct purposeful practice-oriented project work on medium-term and long-term improvement of regional education. Strategic planning documents in accordance with the Law must be published in the media for public discussion. It is necessary to help the residents of the region to show their civic activity in the process of evaluating the proposed activities for the development of education from a creative standpoint to ensure maximum self-realization of young people and their own self-development throughout life.

Feminina ou feminista? A mulher representada na revista o cruzeiro (1950-1970)
Authors: Ferreira Bruna Batista
Published: April 2019

Para compreendermos os movimentos de rupturas e permanências, bem como as correlações entre “feminino” e “feminismo” pela ótica discursiva da mídia impressa, analisamos algumas edições das décadas de 1950 a 1970 de O Cruzeiro: Revista (RJ). As análises dos periódicos compreendidos nesse período mostram-nos fatores decorrentes dos processos discursivos envoltos nas tramas da “indústria cultural”, nos quais, ao tratarem o “ser feminina” e o “ser feminista” como conceitos antagônicos foram construídas e reconstruídas concepções de identidade da mulher.PALAVRAS-CHAVE: Mulher; Feminina; Feminista; Representações; O Cruzeiro.
