A felsőoktatásba bejutott, hátrányos helyzetű fiatalok iskoláinak jellemzése
Authors: Hegedűs Roland
Published: April 2019

A kutatás célja annak vizsgálata, hogy milyen középiskolákból sikeresebb a bejutás a felsőoktatásba, milyen a hátrányos és a nem hátrányos helyzetű tanulók száma és aránya a különböző iskolatípusokban és a különböző fenntartók iskoláiban. Továbbá az említett csoportok között milyen tanulói teljesítménybeli különbségeket tapasztalhatunk az Országos kompetenciamérés (OKM) adatai alapján matematika és szövegértés területeken. Elemzésünk során megvizsgáljuk, hogy milyen az iskolák összetétele, milyen a pedagógusok szakmai teljesítménye. Az elemzéshez két adatbázist használtunk fel, a 2012. évi Országos kompetenciamérésből a 10. osztályos tanulói és telephelyi adatokat, valamint a 2014. évi felvételi adatbázist. A két adatbázis közötti összeköttetést az iskolák oktatási azonosítója adta, így a felsőoktatásba bejutottak között meg tudtuk vizsgálni, hogy ők milyen jellemzőkkel rendelkező iskolából érkeztek. A hátrányos helyzetűekre vonatkozó törvény 2013-as változása okán szükséges volt kialakítani egy hátrányos helyzetű tanulókra vonatkozó változót az OKM adatbázisban, mivel így azonos feltételek mellett tudtuk vizsgálni az adatbázisokban a hátrányos helyzetűeket. Ezt követően az adatbázisokon több dimenziós kereszttábla és ANOVA elemzéseket végeztünk. Eredményeink azt mutatják, hogy hiába tanul lényegesen több hátrányos helyzetű tanuló a szakközépiskolákban, csupán nagyon kis arányuk jut be onnan a felsőoktatásba. A legtöbb hátrányos helyzetű diák a gimnáziumi képzésből tud bejutni a felsőoktatásba. Az egyházi iskolákban jóval kevesebb a hátrányos helyzetű tanuló, mint az állami fenntartásúakban, de ezekből könnyebben jutnak be a felsőoktatásba, köszönhetően annak, hogy ezekben az iskolákban jobb a tanulók teljesítménye. Ennek a hátterében az áll, hogy ezek az iskolák nagyobb mértékben használják a felvételi vizsgát és elbeszélgetést a felvételi eljárásuk során, ezáltal szelektálva a jelentkezők között.

Published: April 2019

We use data collected as part of a baseline survey in 2012 and a survey 5 months post-intervention in 2014 to assess the short-term outcomes of a water supply intervention in Ribáuè, Mozambique. This intervention included the rehabilitation and expansion of a piped water system, revitalization of water committees, and creation of and capacity building for small-scale private water enterprises. Quantitative results suggest that the intervention led to an immediate significant increase in the use of piped water supply at the expense of unprotected wells and other non-revenue generating forms of unimproved water supply with more than a 2.5-fold increase in the usage of yard taps and water kiosks/standpipes and a two-fold decrease in the use of unprotected wells. Family water consumption also increased by approximately 40 L/d, and the point-of-use treatment of water nearly tripled. Economic opportunities were generated for business and small enterprise owners due to the new water supply infrastructure, and piped water infrastructure had additional positive effects for both public and private sanitation facilities.

Influence of drainage network and compensatory techniques on urban flooding susceptibility
Authors: Caprario Jakcemara , Rech Aline Schuck , Tasca Fabiane Andressa , Finotti Alexandra Rodrigues
Published: April 2019

Urban flooding due to accelerated urbanization and the resulting drainage problems have become a worldwide issue and the subject of several studies in recent decades. Alternative and holistic approaches such as sustainable drainage systems have been gaining prominence. Compensatory techniques represent one of these promising alternatives for managing flooding risk in the transition to regenerative urban environments. The goal of this study is to assess the effect of a drainage network together with compensatory techniques on the susceptibility to urban flooding in Campeche District. This study applies the analytical hierarchy process together with a consistency analysis, using overlapping influential parameters in three scenarios. The results show that introducing a drainage system decreases the susceptibility to urban flooding in approximately 27% of Campeche District. In general, considering the absence of a drainage network, it is concluded that its implementation together with compensatory structures provides a reduction of approximately 32% in the susceptibility to urban flooding. It should be noted that, although costly, interventions for the implementation of a drainage infrastructure associated with compensatory techniques are extremely important for disaster reduction and sustainable development.

Recent developments in hydrodynamic stability of two-phase flows
Authors: Osiptsov A.N. , Boronin S.A.
Published: April 2019

In the framework of two-continuum model, the stability of plane-parallel dispersed flows is analyzed. Several flow configurations are considered and several new factors are analyzed. The factors include: particle velocity slip and particle concentration non-uniformity in the main flow, non-Stokesian components of the interphase force and finite volume fraction of the dispersed phase. It is found that the new factors modify significantly the parameters of the fastest growing mode and change the critical Reynolds number of two-phase flows. A method for studying algebraic (non-modal) instability and optimal disturbances to dispersed flows is proposed. While studying the non-modal instability of the dusty-gas boundary-layer flow with a non-uniform particle concentration, we found that the disturbances with the maximum energy gain at a limited time interval are streamwise-elongated structures (streaks). As compared to the flow of a particle-free fluid, optimal disturbances to the dusty-gas flow gain much larger kinetic energy even at the boundary layer width-averaged mass concentration of ten percent, which leads to significant amplification of non-modal instability mechanism due to the presence of suspended particles.

Authors: Khizbullina S.F.
Published: April 2019

On the basis of the continuum dynamics equations the mathematical model of evolution of an incompressible fluid flow in a circular pipe is developed taking into account non-newtonian properties of fluid and non-monotone viscosity dependence on temperature. The qualitative flow picture of anomalous thermoviscous non-newtonian fluid is similar to the flow picture of the anomalous thermoviscous newtonian fluid. Existence of viscosity anomaly leads to reduction of fluid hydraulic resistance.

Authors: de Araujo Filho Nilton Pires , Rios Thiago Leonardo , Jose da Silva Everton , Iafelice dos Santos Thiago , Fernandes da Silva Andre Luis , Borba Alexandre Meireles
Published: April 2019

Background:

Conventional orthognathic surgery can become challenging when multiple goals such as correction of transverse and anteroposterior discrepancies of the dental arches are aimed. Thus, additional procedures such as midline mandible osteotomy for mandibular constriction and tongue reduction due to true macroglossia may be alternatives to a more functional and aesthetical outcome.

Case Report:

A treatment of a 35-year-old female patient with Class III sagittal skeletal pattern marked by an increased angle facial profile, maxillary retrusion, vertical maxillary deficiency, and mandibular protrusion, a Class III malocclusion associated to an edentulous maxilla, partially dentate mandible, transverse mandibular excess and true macroglossia. With an Index of Orthognathic Functional Treatment Need (IOFTN) grade 5, the patient underwent bimaxillary orthognathic surgery, mandible constriction and partial glossectomy. After about a year of follow-up, the patient demonstrated skeletal stability for the orthognathic procedures as well preservation of tongue function.

Conclusion:

The combination of the techniques performed was effective in the treatment of the multifaceted deformities, providing satisfactory function, harmonious facial aspect and enabling effective prosthetic rehabilitation to the patient.

Authors: Dankwah Dominic Agyei , Yamson George Clifford
Published: April 2019

Background:

This cross-sectional survey aimed to ascertain the knowledge of malaria patients in determining the nature and extent of health information needed; accessing the needed health information effectively and efficiently; evaluating such health information and its sources critically in order to use the information.

Methods/Results:

A self-reported questionnaire was given to 155 participants in selected “drug stores” in Ho in the Volta Region of Ghana. Positive relationships were found between respondents whose decision to purchase malaria drugs was based on laboratory tests and high health information literacy skills. Low knowledge of libraries among the respondents was recorded even though there was no significant difference between the health information literacy of those who see the library as a source of health information and those who do not.

Conclusion:

There is a need to involve libraries in the health delivery system in order to help extend literacy training/skills to the citizenry.
Modeling Judges’ Scores in Artistic Gymnastics
Authors: Mack Melanie , Bryan Maximilian , Heyer Gerhard , Heinen Thomas
Published: April 2019

Background:

In artistic gymnastics, performance is observed and evaluated by judges based on criteria defined in the code of points. However, there is a manifold of influences discussed in the literature that could potentially bias the judges’ evaluations in artistic gymnastics. In this context, several authors claim the necessity for alternative approaches to judging gymnastics utilizing biomechanical methods.

Objective:

The aim of this study was to develop and evaluate a model-based approach to judge gymnastics performance based on quantitative kinematic data of the performed skills.

Methods:

Four different model variants based on kinematic similarity calculated by a multivariate exploratory approach and the Recurrent Neural Network method were used to evaluate the relationship between the movement kinematics and the judges’ scores. The complete dataset consisted of movement kinematic data and judgment scores of a total of N = 173 trials of three different skills and routines from women’s artistic gymnastics.

Results:

The results exhibit a significant relationship between the predicted score and the actual score for six of the twelve model calculations. The different model variants yielded a different prediction performance in general across all skills and also in terms of the different skills. In particular, only the Recurrent Neural Network model exhibited significant correlation values between the actual and the predicted scores for all three investigated skills.

Conclusion:

The results were discussed in terms of the differences of the models as well as the various factors that might play a role in the evaluation process.
Invalid Interpretation of Passing Sequence Data to Assess Team Performance in Football: Repairing the Tarnished Legacy of Charles Reep
Authors: Pollard Richard
Published: April 2019

Background:

The relative effectiveness of different styles of play at football has long been the source of heated controversy. The use of passing sequence data has recently been exploited as definitive proof that possession football is more efficient than direct play at producing goals. This has resulted in a number of high profile books, papers and websites claiming that the conclusions of Charles Reep, the founder of football performance analysis and a strong advocate of a direct style, were flawed.

Objective:

The first objective is to explain why passing sequence data cannot be used to give information about the relative merits of direct and possession play and hence why the recent harsh criticisms being made about Reep, his methodology and his conclusions are themselves flawed. The second objective is to review more logical and valid methods of analysis which can be used to assess the effectiveness of different tactics, strategies and playing styles. The third objective is to outline how this methodology has been put to practical and successful use for many years by a handful of performance analysts, but largely ignored by the academic community

Conclusion:

A short passing sequence cannot be used as a proxy for direct play. The uncritical way in which flawed conclusions based on this false assumption have multiplied has unjustly tarnished the legacy of Charles Reep. Other methods exist to examine the relative merits of different playing styles. These should be revisited, especially at a time when more and more performance data is becoming available.
Mean Platelet Volume as a Predictor of Atherosclerotic Severity in Non ST Elevation Acute Myocardial Infarction
Authors: Astuti Yuli , Setianto Budi Yuli , Taufiq Nahar
Published: April 2019

Background: Acute myocardial infarction (AMI) is the leading cause of death in the world. AMI is classified into ST-elevation myocardial infarction (STEMI) and Non-ST elevation myocardial infarction (NSTEMI). Diagnosis and prediction of severity of atherosclerotic in NSTEMI is a challenge. Despite the risk stratification, 14-20% of patients that undergo coronary angiography have normal or non significant coronary artery disease. The role of platelet and the extent of atherotrombosis in patients with NSTEMI are interesting field of research. Mean platelet volume (MPV) reflects platelet size and reactivity. It can be used as a diagnostic marker and may have predictive value. This study aims to prove the role of MPV as a predictor of the degree of atherosclerotic based on Syntax score in patients with NSTEMI undergoing coronary angiography.Methods: This is a cross sectional study enrolled 86 subjects with NSTEMI. Blood samples were taken at the time of admission to the hospital. An MPV was measured by automated machine. Subsequent coronary angiography was performed using standardized method. Syntax score was determined to reflect the atherosclerotic severity. Statistical analysis was used to assess whether an MPV as a predictor of atherosclerotic severity based on Syntax score.Results: The chi-square analysis showed that high MPV could not be used as a predictor of the atherosclerotic severity based on Syntax score in NSTEMI patients (p value =0.5, prevalence ratio 1.15 (95% CI: 0.755-1.753). From multivariate analysis, only smoking factor had an independent relationship with Syntax score (p value =0.047; Odds ratio 2.531(95% CI: 1.012-6.328).Conclusions: High MPV cannot be used as a predictor of atherosclerotic severity based on Syntax score in NSTEMI patients.

Background: Improved functional capacity (FC) and inflammatory marker reduction is a good prognostic factor in post-revascularization cardiac patients. However, there is still limited study investigated association of functional capacity and inflammatory marker after cardiac rehabilitation program. We studied the effects of cardiac rehabilitation (CR) program in the improvement of FC and high-sensitive-C Reactive Protein (hs-CRP) reduction and association between those variables.Methods: This was quasi experimental study in post-revascularization CAD patients who attended phase II CR program at CR gymnasium, Dr. Hasan Sadikin General Hospital, Bandung, from October 2014 to May 2015. The CR program included additional education sessions and consistently strict program intensity on 50-80% heart rate reserve based on formula and Borg scale 11 to 15. Functional capacity and hsCRP were measured before and after the program. Functional capacity was assessed by maximal treadmill test through indirect VO2 max measurement.Results: A total of 37 patients aged 56.05±7.3 years old were analyzed in this study. They consisted mainly of men (81.1%) which 78.4% of them underwent percutaneous coronary intervention (PCI). Our study revealed significant FC improvement after completion of this newly-modified CR program from an average of 6.76 to 8.68 METs (28.4%) ( p<0.001). Hs-CRP reduction was also occurred from mean of 0.49 mg/L to 0.20 mg/L (59.2%) of log hs-CRP level (p= 0.005). Linear regression analysis showed the improvement of fitness was associated with baseline FC (p<0.001) and reduction of hs-CRP was associated with baseline hs-CRP (p<0.001), and not influenced by age, gender, ejection fraction and type of procedure. There is moderate correlation (rs= 0.636, p<0.001) between functional capacity improvement and hs-CRP reduction. Each 1 METs improvement can reduce 9.317 mg/L of transformed hs-CRP level (p=0.006, 95%CI 2.942,15.693).Conclusions: CR program significantly increased functional capacity and reduce hsCRP level in post-revascularization CAD patient, and more prominent in a patient with low baseline functional capacity and high hs-CRP level. Functional capacity improvement and hs-CRP reduction were moderately correlated.

Published: April 2019

Background: Heart disease is the number one cause of death globally. This disease is initiation affected by autonomic dysfunction which will cause disruption of the sympathetic-parasympathetic system. Heart Rate Recovery (HRR) is used to determineautonomic dysfunction.Objective: To determine the relationship of risk factors and cardiovascular treatment to HRR values of 1 minute and 2 minutes.Methods: Cross sectional study to measure HRR 1 and 2 minute undergoing exercise treadmill test for the screening of coronary heart disease in Saiful Anwar hospital in May 2016 until September 2017. Univariate analysis was performed to determine the frequency and proportion of HRR values classified into normal groups (HRR 1 minute > 12x / minute or HRR 2 minutes > 22x / minute) and abnormal groups (HRR 2 minutes ≤ 12x / minute or HRR 2 minutes ≤ 22x / minute).We also performed bivariate analysis using comparative test (Generalized Linear Model) and correlation test (Pearson, Spearman and Eta) and multivariate linear regression analysis.Results: This study found that age, hypertension and beta blocker were significantly associated with HRR abnormalities (p<0.05). HRR 1 and HRR 2 were significantly associated with diabetes mellitus (DM) (p=0.004 and p=0.039) and beta blocker (p=0.042 and p=0.039). Then looking at the relationship of multivariate correlations found a significant correlation between age (β=-0.133, p=0.000) and DM (β=-2.617, p=0.032) at 1 minute HRR and significant correlation with age (β=-0.165, p=0.004) and beta blockers (β=-2,947, p=0.017).Conclusion: increasing of age, diabetes mellitus and beta blockers correlate with decreasing of HRR. The most influential risk factors for HRR values of 1 minute were increasing age and DM, while for HRR values of 2 minutes were increasing age and beta blockers.

Normalización del cuerpo femenino. Modelos y prácticas corporales de mujeres jóvenes del noroeste de México
Authors: Valenzuela Gutiérrez Marissa Eunyce , Meléndez Torres Juana María
Published: April 2019

En este trabajo se analizaron los discursos normalizadores en torno al control del cuerpo femenino, y su apropiación en prácticas y modelos corporales de mujeres jóvenes de clases sociales distintas, en un contexto urbano del noroeste de México. Se utilizó una perspectiva socioantropológica de corte cualitativo, y se realizaron siete entrevistas grupales a mujeres de clase baja, media y alta. El discurso normalizador del cuerpo femenino alude tanto al cuidado de la salud y/o en contra de la obesidad, como a la estética. El cuerpo delgado, sano, en forma y bello se reconoce como el ideal; sin embargo, se valoran modelos corporales  diferenciados por clase social. Las prácticas se identifican bajo el discurso de la salud pero con una motivación estética. Se requiere mayor acercamiento a la experiencia corporal de las mujeres, en una región donde la delgadez es la norma social pero no siempre es compartida, y donde las prácticas corporales son cada vez más invasivas.

En particular, se describen los vacíos regulatorios que dan lugar a la posibilidad de arbitrajes para eludir la normativa y los controles, y se caracterizan los principales actores y operatorias domésticas de la denominada «banca en la sombra». En este contexto, se repasan las principales medidas desregulatorias encaradas por las autoridades del Banco Central desde diciembre de 2015 y sus potenciales impactos sobre la estabilidad y transparencia financiera. Finalmente, se plantean algunas recomendaciones de política para reducir los niveles de fragilidad financiera.

Authors: Da Cunha José Carlos , Cendon Rodrigo Villaverde , Nohama Percy
Published: April 2019

Introdução: nas últimas décadas, novas tecnologias de assistência, muitas baseadas em eletrônica e computação, têm sido adaptadas para formas mais efetivas de promover a substituição sensorial para indivíduos portadores de deficiência auditiva e visual. Métodos: as pesquisas em neurociência cognitiva tiveram um salto qualitativo e quantitativo considerável, permitindo avanços surpreendentes no conhecimento das interações entre as ações cognitivas e sensório-motoras. Isto é especialmente verdadeiro para as melhorias proporcionadas aos indivíduos surdo-cegos que se utilizando de aparatos tecnológicos tem conseguido diminuir a exclusão social a que muitas vezes são submetidos por conta de suas deficiências. Resultados: o presente artigo faz uma revisão das principais tecnologias disponíveis para a acessibilidade e a inclusão social destes indivíduos, buscando desta forma reunir subsídios para futuras pesquisas e desenvolvimentos tecnológicos na área de comunicação alternativa. Conclusão: a inclusão social de qualquer indivíduo esbarra muitas vezes em aspectos educacionais e, diante do quadro de exclusão a que é submetido o portador desta deficiência, a solução parte da melhoria das condições de acesso às formas de comunicação e incremento nos processos cognitivos, diminuindo a barreira existente entre o mundo “real” e o universo destes deficientes.

Naisvihan tunneyhteisö - Anonyymisti esitettyä verkkovihaa Ylilaudan ihmissuhdekeskusteluissa
Authors: Vainikka Eliisa
Published: April 2019

Artikkelissa analysoidaan diskurssianalyysin keinoin anonyyminä käytyjä verkkokeskusteluja suomalaisen Ylilauta-keskustelufoorumin Ihmissuhteet-keskustelualueelta. Miesten ja poikien ihmissuhdekeskustelujen alueelle on tullut viime vuosina vaikutteita radikaalin miesliikkeen, niin sanotun manosfäärin, mielipidevaikuttajien blogeista, jotka pyrkivät muun muassa rakentamaan miesten emotionaalista yhteisöä naisvihan ympärille. Tässä artikkelissa analysoidut keskustelut pyrkivät typistämään sukupuolten väliset suhteet yksinkertaisiksi biologisperustaisiksi totuuksiksi ja stereotyypeiksi ja edustavat siinä mielessä populistista retoriikkaa. Artikkelissa osoitetaan vihamielisten diskurssien ylirajainen kierto sekä tulkitaan naisvihaan yllyttävät yhteisöt intiimin elämän radikalisoitumiseksi, jossa yksilöt pyrkivät levittämään omaksumaansa sanomaa edelleen muille. Keskusteluissa esiintyy myös vastapuhetta, jossa yritetään haastaa naisvihalle perustuvia käsityksiä ja naisvihamielisiä asenteita. Useimmiten keskusteluista tulee kiisteleviä.
Julkaisupaine ja julkaisukulttuurin muutos: Media- ja viestintätieteiden julkaisukanavat ja kansainvälistyminen 2011 - 2017
Authors: Hellman Heikki , Hyödynmaa Merja , Poteri Eija
Published: April 2019

Artikkeli osoittaa media- ja viestintätieteiden julkaisukulttuurin muuttuneen kuluneella vuosikymmenellä. Muutos ilmenee julkaisemisen lisääntyneenä kanavoitumisena kansainvälisiin, aiempaa laadukkaampiin Julkaisufoorumin tasoluokittelemiin tieteellisiin aikakauslehtiin. Englannin kielen valta-aseman vahvistumisen ohella osoitetaan myös yhteisjulkaisemisen lisääntyneen. Uusi julkaisukulttuuri ei kuitenkaan ole syrjäyttänyt kotimaisia julkaisufoorumeita eikä ei-tieteellistä julkaisutoimintaa, joka on lisääntynyt tarkastelujaksolla. Teoreettisesti artikkeli nojaa eri tieteenalojen julkaisukulttuurien välisiä eroja kartoittaneeseen tutkimukseen sekä niin sanottuun julkaisupainehypoteesiin ja siitä käytyyn keskusteluun tieteentutkimuksen ja bibliometriikan piirissä. Artikkelin toiminnallisen kontekstin puolestaan tarjoavat yliopistojen suoriteperusteinen rahoitusmalli ja julkaisemisen kasvanut merkitys rahoituksen suuruutta määräävänä tekijänä. Empiirisenä aineistona käytetään opetus- ja kulttuuriministeriön Virta-tietokantaa, johon on koottu yliopistojen ja korkeakoulujen julkaisutiedot vuodesta 2011 alkaen. Toissijaisena aineistona käytetään Web of Science- ja Vipunen-tietokantoja.
