Telemedicina e uberização da saúde: médicos operários ou consumidores?
Authors: Fontoura Costa José Augusto , Sola Fernanda , Fernandes Garcia Marco Aurélio
Published: October 2020

Objectives: the article aims to analyze changes in the legal categorization of doctors due to possible changes in the medical profession caused by telemedicine. It envisions a possible precariousness of medical work relationships and the uberization of medicine. Methods: the methodological approach starts from the concepts of transaction costs and information developed by the neoinstitutional economy and from the sociological legal analysis made to define a possible scenario of the medical profession and its legal structure. The ideal type of telemedicine mediated by a dominant digital platform is the starting point for the legal analysis of possible categorization of doctors and health services. Based on this ideal model, several considerations are outlined about its possible consequences for the exercise of the medical profession. Results: the main contribution is the legal discussion of the rivalry between categorization as worker or consumer, as well as a possible double incidence of legal regimes. Conclusions: the future roles of doctors as professionals, workers, or consumers will depend not only on the dynamics of the market, but centrally on the legal framework. The control of the quality and social benefits of health services depends on the legal framework, insofar as they are linked to the roles of professionals.

Introduction. Self-perceived health (SPH) is related to disease and well-being. Psychiatrists report burnout and mental disorders more frequently than other physicians, while personality traits related to perfectionism may influence the perception of well-being and health in these professionals. Objective. To compare and determine the association between demographic variables, health conditions, perceived distress, perfectionism, and SPH. Method. A cross-sectional, retrospective, comparative study was performed through an online survey. Psychiatrists and psychiatry trainees who were willing and able to participate were included. Demographic variables and self-reports of mental and physical conditions were examined. SPH was rated on a 10-point visual analogue scale and perfectionism through the Multidimensional Perfectionism Scale. Comparative analyses and multiple linear regression models were performed. Results. Three hundred and thirty psychiatry trainees and 355 psychiatrists were recruited. Psychiatrists reported more physical conditions (32.4% vs. 15%, p < .001), distress (p < .001), and perfectionism (p < .001). Major depression and anxiety were present over 50% of all participants. A higher SPH was associated with being partnered and having higher distress levels in psychiatry trainees and with the absence of a physical health condition, less concern over errors, and higher personal standards in psychiatrists. Discussion and conclusion. Self-oriented perfectionism may have a significant motivational component, accentuated by competitiveness and individualism. Being married and having higher levels of distress in psychiatry trainees appears to create a sense of satisfaction with achievements. The implementation of strategies to prioritize and meet goals is necessary to have an adequate work-life balance without affecting personal satisfaction or the sense of achievement.

Introduction. Physicians of Intensive Care Units (ICU) have a potential risk to develop negative outcomes such as emotional exhaustion and secondary traumatic stress (STS). Specifically, job demands in these units (i.e., work stressors and emotional effort) may positively predict these outcomes, whereas personal resources such as harmonious passion and self-compassion may diminish them. Objetive. To design a specific intervention for physicians in ICU and provide preliminary evidence of its effectiveness. Method. A brief intervention of five weekly sessions (two hour-sessions) was carried out with four physicians in ICU in a hospital in Mexico. Other four physicians were selected as a control group. The intervention was aimed at reducing emotional exhaustion and STS by increasing harmonious passion and self-compassion, and diminishing the emotional effort. Results. The intervention group showed a significant reduction in: a) work stressors (2/4 physicians; RCI = .21); emotional effort (1/4 physicians; (RCI = .60); emotional exhaustion (2/4 physicians; RCI = .34); and STS (3/4 physicians; RCI = .26). One physician experienced a significant increase in harmonious passion (RCI = 1.00), but the intervention seems to maintain high levels of this and self-compassion in comparison with the control group. The control group showed a worse result in its outcomes. Discussion and conclusion. Despite the limitations, this study provides preliminary evidence for effectively reducing emotional exhaustion and STS. Our findings highlight the individual analysis of the effective tools per physician and address interventions focused on harmonious passion and self-compassion. This study calls for future research concerning intervention proposals in ICU with follow-up measures to diminish the negative consequences in the long-term.
The role of Community Mental Health in a new architecture of World psychiatry and Global Mental Health
Authors: Alarcón-Guzmán Renato D. , Castillo-Martell Humberto
Published: October 2020

Introduction. The influx of new knowledge and scientific contributions into contemporary world psychiatry has counted on a vigorous dissemination through technology-inspired means. This process has led to the realities of Global Mental Health (GMH) inspired by “a new epistemology” of mostly positivistic roots. Objective. To explore the basis of these realities and the resulting homogenization attempts of psychiatry as a medical, clinical, and research discipline. Discussion and conclusion. The need for “a new architecture” of contemporary psychiatry is discussed as a reflection of a correct epistemological exercise and a renewed pact between professionals and communities, materialized in and enriched by the re-emerging Community Mental Health (CMH) movement. The essential bases of the movement are presented, and its mutually collaborative, multidisciplinary, integrated, and realistic nature, as reflected in national efforts like Peru’s in Latin America, is described.

Doğu Akdeniz’deki Doğal Gaz Rezervlerinin Ekonomik ve Güvenlik Boyutuyla Türkiye Açısından Değerlendirmesi
Authors: Hava Hüseyin Tamer
Published: October 2020

Doğu Akdeniz, geçmişten günümüze kadar olan her dönemde jeopolitik, jeoekonomik ve jeostratejik öneme sahip olmuştur. Ulaşım, ticaret gibi konularda merkez bölge olma konumunu hiç kaybetmemiştir. Son zamanlarda bölgede bulunan önemli miktardaki hidrokarbon rezervlerinin bölgenin enerji merkezi olma potansiyelini artırması ve tüm tarafların uzlaştığı münhasır ekonomik bölgelerinin bulunmayışı buraya yönelik kıyasıya yaşanan mücadelenin giderek artacağını göstermektedir. Coğrafi konum olarak küresel enerji hareketliliğine sahne olan Türkiye’de bu mücadelenin bir parçasıdır. Bu doğrultuda elbette ki Türkiye’de bölgesel enerji merkezi olmayı hedeflemektedir. Ancak bu çeşitli riskleri de beraberinde getirmektedir. Bu perspektiften hareketle çalışmada, bölgede son zamanlarda yaşanan gelişmelerin yarattığı sonuçlar, jeopolitik, jeostratejik, jeoekonomik ve uluslararası güvenlik boyutlarıyla incelenerek çözüm önerilerinde bulunulacaktır.
The Semiformality of Teacher Leadership on the Edge of Chaos
Authors: MARGOLIS JASON
Published: October 2020

In this article, Jason Margolis draws from complexity theory to explore the twenty-year negotiation between formal and informal teacher leadership in research and practice, making the case that there has been a drift toward a conception of semiformal teacher leadership in the field. Through both theory and examples, he illustrates how semiformal teacher leadership has the potential to afford school systems and educators both information and processors of information they likely would not otherwise have. Teacher leaders, in roles that are neither inflexible or ill-defined, can carve out intentional spaces on the edge of chaos to promote professional learning and communication in ways that solely school teachers or solely school leaders may not. In these spaces, productive complexity, agency, and systemic learning can coevolve.
Authority and Control: The Tension at the Heart of Standards-Based Accountability
Authors: SCHNEIDER JACK , SAULTZ ANDREW
Published: October 2020

In this essay, Jack Schneider and Andrew Saultz offer a new perspective on state and federal power through their analysis of authority and control. Due to limitations inherent to centralized governance, state and federal offices of education exercised little control over schools across much of the twentieth century, even as they acquired considerable authority. By the 1980s, however, such loose coupling had become politically untenable and led to the standards and accountability movement. Yet, greater exertion of control only produced a new legitimacy challenge: the charge of ineffectiveness. State and federal offices, then, are trapped in an impossible bind, in which they are unable to relinquish control without abdicating authority. Schneider and Saultz examine how state and federal offices have managed this dilemma through ceremonial reform, looking at two high-profile examples: the transition from No Child Left Behind to the Every Student Succeeds Act, and states’ reaction to public criticism of the Common Core State Standards.
Total hip and knee arthoplasty: on the issue of indications for surgery
Authors: Vorokov Alim A. , Bortulev Pavel I. , Khaydarov Valery M. , Linnik Stanislav A. , Tkachenko Aleksandr N.
Published: October 2020

Background. Both in Russia and across the world, the annual frequency of total hip and knee replacement has increased, which has inevitably led to an increase in the number of patients with unsatisfactory treatment outcomes. This failure can primarily be attributed to the complications that arise, some of which arise due to the wrong choice of treatment approach.
Aim. To analyze the publications on the results of treatment of patients with hip osteoarthritis and knee osteoarthritis by total hip and knee replacements.
Materials and methods. The literature data were searched in open electronic databases of scientific literature PubMed and eLibrary using the following keywords and phrases: total hip/knee replacement, complications, patient satisfaction, age, obesity. The search depth was 20 years.
Results. The data indicated a rise in the total number of such patients recorded annually. A significant number of publications, both in Russian and foreign literature, are devoted to the analysis of complications that mainly determine the patients satisfaction with an operation. In addition, these articles analyze the issues of determining the indications and contraindications in applying these methods of treatment. However, it is not uncommon for orthopedists to form a decision for performing an operation based on their subjective experience. At the same time, one of the circumstances that influences the decision-making is the lack of a stable system in the conservative treatment of degenerative joint diseases. According to the data from health care organizations, hip and knee replacements are the only available method for treating osteoarthritis. This circumstance may lead to an unjustified expansion of indications for arthroplasty, which would definitely affect the outcomes of treatment. In this situation, it is critical to search for precise criteria to identify the indication for total hip and knee arthroplasty.
Conclusion. Unjustified expansion of indications for endoprosthesis leads to an increase in the number of complications, which in turn leads to an increase in the number of patients who remain unsatisfied with the outcomes of hip and knee arthroplasty in the long term. This circumstance encourages special scientific research to clarify the indications and contraindications for hip and knee replacements, especially in young and middle-aged people.
A Shallow Shock: The 25 February 2019 ML 4.9 Earthquake in the Weiyuan Shale Gas Field in Sichuan, China

Published: October 2020

Earthquakes rarely occur at extremely shallow depths, for example, less than 2 km. Even for induced earthquakes that are typically shallower than tectonic events, only very small ones have been reported in such depths. The ML 4.9 earthquake (Mw 4.3) that struck the Rongxian County, Sichuan, China on 25 February 2019 was an extremely shallow event. Seismological and geodetic data constrained the mainshock depth at ∼1  km with a thrust-faulting mechanism, consistent with the Molin fault orienting northwest. Two foreshocks with magnitudes larger than 4 occurred on an unmapped fault striking northeast, right next to an injection well where hydraulic fracturing (HF) was conducted. The focal depths of the two foreshocks were at ∼2.7  km, coinciding with the depth of HF. Coulomb failure stresses of the two foreshocks on the Molin fault was ∼3  kPa, smaller than typical static triggering threshold (10 kPa), and thus their triggering effects were mild. As the fault was hydraulically sealed from HF, we suggested that the ML 4.9 earthquake was possibly triggered by nearby HF activities through poroelastic stress transfer. Such findings held significant implications for shale gas development by considering seismic hazard associated with shallow faults.
Policy through Practice: How Tribal Education Department Leaders View Educational Policy Problems
Authors: Poitra Christie M.
Published: October 2020

This article examines how tribal education department leaders perceive the process of educational policy problem recognition and definition in their governments. This piece presents the perspectives of two education department directors working in two different federally recognized tribal governments located in Northern California. The data presented in this article was gathered through multiple interviews with the education department directors. The interviews were recorded, then transcribed and analyzed for themes sentence-by-sentence with the use of open coding methodology. The study argues that policy problem recognition and definition processes are, in part, shaped by (1) the expertise and ideologies of the department leadership within tribal governments; (2) the hands-on work of department leadership in the community; and (3) the flow of policy problem indicators from departments to council.

Published: October 2020

Adequate Fluid and electrolyte balance in trauma patients is a task with complex decisions that are often complicated by coagulopathy and blood loss. An adequate volume of blood in the circulation is essential to maintain cerebral perfusion and vital function of the heart, kidneys, lungs, and other organs. Acute blood loss has been identified as one of the major causes of preventable deaths on arrival at hospital. The aim of fluid resuscitation should be to restore critical organ perfusion. This review discusses the availability of various options of Intravenous fluids and their co-relation with body’s demand in fluid management of trauma patients.
Use of Bézier curves in the design of the displacement law of the cam-follower mechanism: Von Mises effective Stress
Authors: Acevedo-Peñaloza Carlos Humberto , Ramón-Ramón Sergio Andrés , Bustos-Urbano Víctor Jhoel
Published: October 2020

Designing cams by BézierCurves has become increasingly common, since the mathematical development of this method is less complex. Bezier curves are Bernstein-based polynomials under a unitary domain, and in that sense, this article presents the design of a cam using Bezier curves of degrees 5, 7 and 9. And beyond, this article seeks to show the variation of the effective effort of Von Mises in a cam-follower mechanism composed of a disc cam and a roller follower with translation movement and force closure. The expressions that allow determining the variation of Von Mises' effort for each of the curves used are presented. This variation is presented by means of graphs in which it is observed that as the degree of the curve increases, the magnitude of the efforts is greater, and this increases the probability of failure in the mechanisms. In addition, it was found that there is an inverse relationship between the stress and the radius of the primary circle of the cam

Published: October 2020

En las últimas décadas se ha intensificado la búsqueda de materia prima proveniente de recursosrenovables para la producción de polímeros, elastómeros, resinas, espumas, etc., que disminuyan el uso industrial de compuestos petroquímicos. En este trabajo se usó el aceite extraído de la semilla de higuerilla (Ricinus communis) por su contenido de ácido ricinoleico (92,3 %), por su fácil producción y por no ser comestible; la síntesis del poliuretano adhesivo se hizo a través de reacciones de transesterificación y polimerización; con él se pegaron láminas de Guaduaangustifolia Kunth y se determinaron las características mecánicas de la estructura; se obtuvo que la resistencia a la compresión paralela a la fibra es de 43±3 (MPa), y la cortante paralela a la fibra es de 5,9±0,9 (MPa). La determinación de la relación molar adecuada y el seguimiento de la reacción durante la síntesis se hicieron con espectroscopía infrarroja con transformada de Fourier y la estructura del producto final se analizó con difracción de rayos X. A través de calorimetría diferencial de barrido se obtuvo la temperatura de transición vítrea del producto de -26.4 °C y se usó la técnica de relajación térmica para medir su calor específico, mientras que su difusividad térmica y el coeficiente de dilatación térmica se estimaron con la técnica fotoacústica.
Discrete-time inverse optimal control for a reaction wheel pendulum: a passivity-based control approach
Authors: Montoya Oscar Danilo , Gil-González Walter , Martin Serra Federico
Published: October 2020

In this paper it is presented the design of a controller for a reaction wheel pendulum using a discrete-time representation via optimal control from the point of view of passivity-based control analysis. The main advantage of the proposed approach is that it allows to guarantee asymptotic stability convergence using a quadratic candidate Lyapunovfunction. Numerical simulations show that the proposed inverse optimal control design permits to reach superiornumerical performance reported by continuous approaches such as Lyapunov control functions and interconnection,and damping assignment passivity-based controllers. An additional advantageof the proposed inverse optimal controlmethod is its easy implementation since it does not employ additional states. It is only required a basic discretizationof the time-domain dynamical model based on the backward representation. All the simulations are carried out inMATLAB/OCTAVE software using a codification on the script environment.

Additive metal manufacturing has undergone a revolution in recent years, being able to be incorporated in several industries such as aeronautics, automotive and even in medicine, allowing the manufacture of complex parts with fewer steps in the process, which translates in material savings and cost reduction. In this work, the corrosion of low carbon steel obtained by depositing consecutive layers is carried out, using electrochemical impedance spectroscopy and electrochemical noise immersed in a 0.1 M NaCl solution, establishing a comparison between the metal of contribution and deposited material. The layers of the material are characterized microstructurally and mechanically using scanning electron microscopy and Vickers microhardness. Overall, the results show a good response of the material to the action of the electrolyte after the immersion time, on the other hand, the microstructural results allow identifying the formation of 3 zones due to the cooling of the material. The microhardness of the steel does not show great changes between the zones, however, there is a slight increase in the intermediate zone due to the reduction in grain size. These studies allow researchers to know the behavior of these materials in applications that require contact with corrosive solutions of this nature.

The short description of scientiﬁc equipment of МРТ (multichannel recorder of temperatures) is resulted and experimental results about current temperatures in local zones of containers of the scientiﬁc equipment, received in 42 daily ﬂight of a space vehicle ”FOTON-M” № 4 are presented. It is shown, that the most essential factors deﬁning a thermal mode in containers of scientiﬁc equipment, their position on the external surface of the spacecraft, focused almost during all ﬂight by panels of solar batteries on the Sun and conditions on coils or, that’s the same, current deviation of a normal to a plane of orbit spacecraft from a direction on the Sun. Thus time numbers of data about values of temperatures have strongly pronounced oscillatory character with the orbital period of movement of spacecraft and with high level of correlation between them, and also dependence values of temperatures from the position of a plane of orbit of a spacecraft concerning the Sun.

The problem is considered on a segment [0,1] (more general case of segment[0, a] is reduced to considered). On the ends of a segment the solution of y and its second derivative of y′′ areequal to zero. Right part of an equation f (x, y) isn’t negative at x\geq 0 andat all y. Performance of suﬃcient conditions is easily checked. Performance ofthese conditions is easily checked. In the proof of existence the theory of conesin banach space is used. Also apriori estimates of positive solution, which ispossible to use further at numerical construction of the solution are obtained.
NECESSARY NON-LOCAL CONDITIONS FOR A DIFFUSION-WAVE EQUATION
Authors: Mamchuev M.O.
Published: October 2020

In this article, diﬀusion-wave equation with fractional derivative in Rieman- n-Liouville sense is investigated. Integral operators with the Write function in the kernel associated with the investigational equation are introduced. In terms of these operators necessary non-local conditions binding traces of solution and its derivatives on the boundary of a rectangular domain are found. Necessary non-local conditions for the wave are obtained by using the limiting properties of Write function. By using the integral operator’s properties the theorem of existence and uniqueness of solution of the problem with integral Samarski’s condition for the diﬀusion-wave equation is proved. The solution is obtained in explicit form.
Cases of integrability corresponding to the pendulummotion on the plane
Authors: Shamolin M.V.
Published: October 2020

In this article, we systemize the results on the study of plane-parallel motion equations of ﬁxed rigid body-pendulum which is placed in certain nonconserva- tive force ﬁeld. In parallel, we consider the problem of a plane-parallel motion of a free rigid body which is also placed in a similar force ﬁeld. Thus, the non-conservative tracking force operates onto this body. That force forces the value of certain point of a body to be constant for all the time of a motion, which means the existence of nonintegrable servoconstraint in the system. The obtained results are systematized and served in the invariant form. We also show the nontrivial topological and mechanical analogies.
A PROBLEM WITH SECOND KIND INTEGRAL CONDITIONS FOR HYPERBOLIC EQUATION
Authors: Pulkina L. S. , Savenkova A. E.
Published: October 2020

In this paper, we consider a problem for one-dimensional hyperbolic equation with second kind integral conditions and prove unique solvability. To prove this statement we suggest a new approach. The main idea of it is that given nonlocal integral condition is equivalent with a different condition, nonlocal as well but this new condition enables us to introduce a definition of a generalized solution bazed on an integral identity and derive a priori estimates of a required solution in Sobolev space. This approach shows that integral conditions are closely connected with dynamical conditions.
CORRECTNESS OF THE LOCAL BOUNDARY VALUE PROBLEM IN A CYLINDRICAL DOMAIN FOR ONE CLASS OF MULTIDIMENSIONAL ELLIPTIC EQUATIONS
Authors: Aldashev S. A.
Published: October 2020

Correctness of boundary value problems in a plane for elliptical equations has been studied properly using the method of the theory of analytic functions. At investigation of analogous problems, when the number of independent variables is more than two, there arise principle difficulties. Quite good and convenient method of singular integral equations has to be abandoned because there is no complete theory of multidimensional singular integral equations. Boundary value problems for second-order elliptical equations in domains with edges have been studied properly earlier. Explicit classical solutions to Dirichlet and Poincare problems in cylindrical domains for one class of multidimensional elliptical equations can be found in the authors works. In this article,the author proved that the local boundary value problem, which is the generalization of Dirichet and Poincare problem, has only solution. Besides, the criterion of uniqueness of regular solution is obtained.
EXPERIMENTAL DETERMINATION OF COEFFICIENTS OF A MULTIPARAMETER DECOMPOSITION OF FIELD OF CRACK TIP STRESSES: PHOTOELASTICITY METHOD
Authors: Stepanova L. V. , Dolgikh V. S.
Published: October 2020

The purpose of this study is multiparameter asymptotic analysis of the stress field in the immediate vicinity of the crack tip in a linearly elastic material and construction of complete asymptotic expansion of M. Williams stress field in the vicinity of the crack tip. Multiparametric analysis of the stress field is based on the polarization-optical methods of mechanics of a deformable solid (the method of photoelasticity). Digital processing of the results of optoelectronic measurements performed on a series of samples with cracks and notches is carried out. Different classes of samples from optically sensitive materials, in particular a sample with two collinear cracks under conditions of normal detachment, were considered. A set of programs has been prepared that makes it possible to determine the scale (amplitude) multipliers of complete asymptotic expansion of M.Villiams for the stress field at the crack tip. Using the basic law of photoelasticity, first five coefficients of complete asymptotic expansion of M. Williams are calculated. The results of the experiments are compared with the available analytical solution. It is shown that the results of processing optoelectronic measurements are in good agreement with the analytical solution obtained for an infinite plate with two collinear cracks.
The Pursuit of the Source, or The Inevitability of Death
Authors: Persson Mats , Karlsson Jan Ch.
Published: October 2020

The purpose of this article is to apply the method of the genre of studying chains of references to an instance of a secondary source of the contested concept of ‘resistance to change’ back to the primary source and thereby exercise criticism of the sources. This includes discussing whether the theory itself is empirically sustainable or sufficiently scientifically grounded. In the article, we adopt a theoretical lens of Critical Realist Discourse Analysis, mainly because it is sensitive to the importance of the influence of nondiscursive social positions on discourses. The primary source of the chain of theories of resistance to change turns out to be Kübler-Ross’s model of stages of dying patients’ reactions to their immanent death. We find that the model is systematically misinterpreted to fit the empirically false idea of resistance to change of the ideological discourses of management research.

Published: October 2020

In contemporary working life of Nordic countries, employee involvement and well-being are emphasized and organizational functions and demands are continuously changing. Thus, the study of human resource management (HRM) practices and their consequences for employees is relevant. This study examines conflicts related to HRM in Finnish project-based companies and provides new information on the implications of conflicts in HRM practices for theorists and practitioners. The research was conducted qualitatively using content and thematic analysis. The findings suggest that conflicts framed within HRM practices are generally the result of the practices and expectations of the organization and management not meeting the views and expectations of the employees. Moreover, the lack of transparency and deficient or even absent HRM practices generate conflicts. The consequences of conflicts range from motivational problems and individual employees’ fatigue to the deterioration of team and organizational performance.
Employment Exits Near Retirement Age: An Agency-analysis
Authors: Kosonen Hanna , Keskinen Katri , Nikander Pirjo , Lumme-Sandt Kirsi
Published: October 2020

Population aging has prompted international governing bodies to recommend extending work careers and postponing retirement age. Retirement decisions cannot be fully reduced to either structural influences or individual agency. Older workers may face several limiting factors when continuing their careers beyond the official retirement age, including internalized attitudes towards aging at work. Our aim is to develop agency analysis that involves both structural and individual components to fully illustrate the heterogeneity of older workers and their retirement decisions. By studying qualitative interview data via thematic content analysis and a modality-based agency framework, we found that agency manifests in various different ways in older employees’ work exit accounts and that the relationship between individual agency and structures is complex. We conclude that agency analysis of aging employees offers insights into the complexity of the retirement process and may thus inform us about how to help extend work careers.
Típusok, csoportok, tájak a moldvai magyarban
Authors: Péntek János
Published: October 2020

1959-ben jelent meg a debreceni egyetem folyóiratában, a Magyar Nyelvjárásokban Szabó T. Attila alapvető tanulmánya A moldvai csángó nyelvjárás kutatásának története címmel. A kolozsvári tanszéken végzett nyelvföldrajzi kutatási projektekre támaszkodva megállapítja, hogy a moldvai magyar nyelvjárási régión belül három nyelvjáráscsoport különíthető el: székelyes, északi és déli. Ez a végkövetkeztetése eltér számos korábbi szerző véleményétől, akik azt állították, hogy a moldvai magyaroknak két típusa van: a székely és a magyar. A terminológia korábban azért is volt zavaró, mert a csángó elnevezést egyes szerzők az eredeti (magyar) csoport jelölésére használták, miközben általánosan az összes moldvai magyarra is használták. Jelen dolgozat szerzője amellett érvel, hogy a későbbi nyelvföldrajzi kutatások a fenti háromoldalú besorolást tévesnek mutatják, és a korábban feltételezett kettősségi eredet, nyelvjárástípus és területi eloszlás tekintetében is igazoltnak bizonyult. A két nyelvjárás azonban folyamatosan dialektuskeveredésen megy keresztül, és még inkább befolyásolja a domináns helyi román nyelvjárás és a román standard nyelvjárás. Ennek a kettősségnek a kifejezésére a szerző a mezőségi és a székely elnevezést javasolja.
A magyar nyelv első kognitív szemléletű grammatikája
Authors: Andor József
Published: October 2020

Jelen összefoglaló kritikai értékelést ad a mai magyar nyelv főbb nyelvtani jelenségeiről szóló első kognitív alapú, átfogó, nagyrészt korpusz alapú áttekintésről. A megközelítés központi kérdése a grammatikai reprezentáció egyes szintjének, összetevőinek séma-alapúsága, különös tekintettel a jelentéskonstrukció általános funkcionális szerepének, valamint az interfészkapcsolatok komplexitásának tárgyalására és értelmezésére. Ez utóbbi viszonyok a funkcionális rendszer egészének, a nyelvtan felépítésének működésére hatnak, amelynek reprezentációjának jelenségeit ez a magyar grammatológia történetírása szempontjából meghatározó jelentőségű kézikönyv koherensen írja le és tárgyalja.
Előtagos és előtag nélküli vonatkozó névmások versengése a középmagyar kor első félévszázadában
Authors: Dömötör Adrienne
Published: October 2020

Az ómagyar kortól napjainkig tartó folyamat az előtagos és előtag nélküli relatív névmások versengése. Az innovatív változat egy demonstratív névmás és egy relatív névmás sorozatának újraelemzésével jött létre. A mai magyar relatív névmások kialakulásában egymást követő grammatizálódási folyamatokat figyelhetünk meg. Az előtagos változat a késő ómagyar óta dokumentálható. Az előtagú formák terjedése a középmagyar kor első évtizedeiben lendül fel. A cikk azt a kérdést vizsgálja, hogy melyik regiszternek volt a vezető szerepe ebben a fejlesztésben. A beszélt élőnyelvhez közeli nyelvhasználatnak volt-e a nyelvi változások elindításának elsődleges terepe? Vagy a könyvnyomtatás által formált írott nyelv lehetővé tette az innováció könnyebb fejlődését? Körülbelül 4000 adatpontból álló mintán vizsgáltam a ki ~ a(z)ki, mi ~ a(z)mi  és a mely ~ a(z)mely párok viselkedését. Az eredményeket százalékos eloszlást ábrázoló diagramok segítségével mutatom be. Az eltérések nagyságára vonatkozó állítások jelentőségét is teszteltem. Emellett kitérek a nyelvi változás terjedésének általános kérdéseire is. A dolgozat fő eredménye, hogy a három névmáspárból kettő esetében a könyvnyelv elsőbbséget élvez a beszélt nyelvvel szemben. A bibliafordítások idiómája azonban mindkét regiszterrel szemben az első helyet foglalja el. Így tehát elmondható, hogy a kifinomultabb nyelvhasználat és a csiszolt stílus nyitottabbnak tűnik az innovációra a vizsgált jelenség tekintetében.
A magyar nyelv néhány jegyének eredetéről
Authors: Pusztay János
Published: October 2020

A cikk a magyar nyelv hét jellemzőjét tárgyalja: a két ragozás megkülönböztetését, funkcióit és használatát – a fókusz alapú megközelítés és a tárgyközpontú megközelítés szembeállítását; a személyes névmásokra visszamenő személyragok és a névmásokra visszamenőek; szamojéd–magyar megfeleltetések a verbális paradigmákban; feszítés és oldal jelölése; kettős és többes utótagok kialakulása meghatározó/összekötő elemekből; az objektum helyhatározói utótaggal való megjelölése; a névértékek predikatív deklinációja és a -t múlt idő. Ezek a jelenségek a magyar nyelv (paleo-)szibériai hátterére utalnak.
Névszociológiai analízis Szentpéterszeg helynevei alapján (2. rész)
Authors: E. Nagy Katalin
Published: October 2020

A helynévhasználat kérdései már régóta foglalkoztatják a kutatókat, így nem meglepő, hogy megjelent egy új résztudomány, amelyet a helynévszociológiának neveznek. Jelen írásomban egy új esettanulmány bemutatását tűztem ki célul a helynévszociológiai empirikus vizsgálatok körének bővítése érdekében. A Hajdú-Bihar megyei község, Szentpéterszeg helyneveit az alábbi szempontok szerint elemzem: Feltárom a nem és az életkor hatását a helynévismeretre, és a helynévrendszer egyes elemeit ismertségi szintjük szerint osztályozom. Végezetül egy névközösségi vizsgálatot is végzek, mellyel közelebb kerülhetünk a névközösség fogalmának meghatározásához.

Differences in Clinical Management and Outcomes of American Indian and White Women Diagnosed with Endometriosis
Authors: Spagnolia Alessandra , Beal James R , Sahmoun Abe E
Published: October 2020

Objective: Endometriosis is a chronic, painful disease that can be disabling. There is a scarcity of research on the clinical management and outcomes of endometriosis in American Indian (AI) women. The aim of this study was to determine whether there are discrepancies between AI and White women in symptoms at presentation, initial diagnosis methods, clinical management, and long-term outcomes of endometriosis, in a rural state.
Materials and methods: This retrospective study described and compared the clinical management and long-term outcomes of AI and White women diagnosed with endometriosis. All statistical tests were two-tailed with p-value < .05 considered to be significant.
Results: 110 women diagnosed with endometriosis were included in the study, with 50% (n = 55) AI and 50% (n = 55) White. White women were more likely to have private insurance (80% vs. 42%; p < 0.001). AI women were more likely than White women to report abdominal pain at diagnosis (20.3% vs. 9%;  p = 0.010), and be diagnosed with mild endometriosis symptoms at the initial visit, (44.4% vs. 10%; p = 0.051). White women were more likely to report a reduction or cessation of pain compared to AI women (63.3% vs. 34%; p = 0.004).
Conclusion: We found the majority of women continue to report pain long after endometriosis diagnosis. AI women were less likely to report a reduction or cessation of pain. Future research should investigate why pain is more persistent in AI women.
