ОСОБЕННОСТИ И ПРАВОВЫЕ ОСНОВЫ ВЗАИМООТНОШЕНИЙ ЛИЧНОСТИ, ОБЩЕСТВА И ГОСУДАРСТВА
Authors: Кагерманов А-С.С.
Published: July 2020

В статье рассматриваются особенности и правовые основы взаимоотношений личности, общества и государства. Подчеркивается, что в теоретических исследованиях и на практике личность воспринимается одновременно в качестве объекта и субъекта этих взаимоотношений, нуждающегося в защите со стороны государства. Вместе с тем отмечается, что существование установленных на законодательном уровне прав и свобод личности не освобождает последнюю от обязанностей, которые возникают у нее перед государством. Взаимоотношения личности и государства четко определены институтом гражданства и привязаны к устанавливаемым с его помощью рамкам. Гражданство дает личности возможность пользоваться предоставляемыми государством правами и свободами и обеспечивает государству возможность получить «обратную связь» от личности, проявляющуюся в выполнении установленных для нее обязанностей. Вместе с тем установление слишком большого перечня обязанностей и непредставление того количества свободы, которое необходимо для развития личности, несомненно, приведет к конфликтам внутри государства. Но и предоставить полную свободу личности государство не способно – отказ от установления обязанностей для гражданина приведет к распаду государственности и неисполнению идеи сосуществования правового государства и гражданского общества. Что касается последнего, то его сложно создать без наличия у личности гражданского правосознания – стремления не просто пользоваться своими правами и свободами, но и осознания своей ответственности перед обществом и государством, принятия необходимости следования закону. Общество само по себе придерживается определенных рамок, которых должна придерживаться каждая входящая в него личность.

ARQUEOBOTANICA DE CUEVA HUENUL 1 (NEUQUEN, ARGENTINA): SELECCIÓN Y PROCESAMIENTO DE ESPECIES VEGETALES
Authors: Llano Carina , Sosa Paula , Barberena Ramiro , Sánchez Clara
Published: July 2020

En este trabajo se presentan los últimos análisis arqueobotánicos del sitio Cueva Huenul 1, emplazado en el norte de la Provincia del Neuquén (noroeste de Patagonia, Argentina). La secuencia cronológica del sitio abarca en forma discontinua desde la transición Pleistoceno-Holoceno hasta tiempos recientes. El objetivo es realizar un análisis diacrónico de las pautas de selección antrópica de especies y los patrones de procesamiento. Los resultados indican que los cazadores-recolectores utilizaron plantas disponibles localmente durante toda la secuencia ocupacional. A nivel temporal, se observan cambios tanto a nivel de la diversidad de especies representadas como, en el caso específico de Prosopis, en las pautas de procesamiento y consumo. Algunos taxones consumidos en el Holoceno tardío constituyen indicadores de estacionalidad y sugieren ocupaciones estivales en la cueva. Asimismo, se discuten datos sobre la presencia de especies domésticas en el registro, tales como Lagenaria sp. y Zea mays. Estos estudios se conectan con discusiones más amplias sobre la economía y organización espacial de las sociedades que habitaron el noroeste de Patagonia desde el poblamiento inicial.
Procesamiento alimenticio y tecnológico de guanacos durante el Holoceno tardío: el caso del sitio costero Marazzi 32 (Tierra del Fuego, Chile)

Published: July 2020

El presente trabajo entrega los resultados zooarqueológicos y tecnológicos correspondientes al análisis del conjunto de guanacos provenientes del sitio Marazzi 32, bahía Inútil, isla Grande de Tierra del Fuego. El yacimiento, con dataciones entre 560-635 años AP, es uno del conjunto de sitios tardíos a cielo abierto ubicados en el fondo de la bahía. Se destaca, particularmente, por un considerable registro óseo de cetáceos, mayoritariamente localizados en superficie, y por la predominancia de guanacos en relación a otros mamíferos marinos, aves y otras especies. Los resultados de las excavaciones sistemáticas permitieron confirmar la importancia de los restos de guanaco en la subsistencia y aprovisionamiento de materias primas óseas, apoyando la teoría económica que tradicionalmente ha considerado que los recursos terrestres jugaron un rol fundamental para los grupos humanos que habitaron el norte de la isla durante el Holoceno tardío.Se discute el interés especial de la explotación de guanacos en el sitio, evidenciado por un aprovechamiento mayoritario de individuos juveniles y se analizan las estrategias de explotación, cadena alimentaria y, de manera preliminar, la gestión tecnológica de la especie.

Influence of Provider Interaction on Patient's Readiness Toward Audiological Services and Technology
Authors: Amlani Amyn M.
Published: July 2020

Background Patients and providers recognize the importance of patient-centered care. Clinical interactions, however, suggest that audiologists maintain their traditional provider-centered approach.

Purpose The primary purpose of this study was to assess the degree to which provider interaction influenced patient readiness toward audiological services using the neobehavioral concept of need recognition described in consumer decision-making.

Research Design We used a randomized, within-group experimental approach using survey responses to quantify predisposed expectations on ten dimensions toward service and technology provision 2 weeks before and 2 weeks after an audiological assessment. Responses were also categorized as a function of the respondent-perceived professional setting of the provider (medical, rehabilitation, and consumer electronics).

Study Sample Survey respondents included 618 adults {186 males (mean age = 63.1 years; standard deviation [SD] = 5.3) and 432 females [mean age = 58.4 years; SD = 6.2]} from across the United States.

Data Collection and Analysis Data were analyzed using two approaches. First, we used a two-step cluster analysis procedure that revealed natural groupings (i.e., profiles) of respondent characteristics of the ten dimensions. Second, we compared within-group mean differences between pre- and postappointment responses using a univariate analysis of variance, with mean differences reported as a function of professional setting and preappointment responses serving as the control condition.

Results Results revealed that the predisposed expectation profiles among the ten dimensions differed among the professional settings, with rehabilitation having the highest mean response values and consumer electronics having the least mean response values. A descriptive analysis indicated that respondents in the rehabilitation and medical settings presented the greatest interest in amplification before the patient-provider interaction, but the least interest afterward. In addition, postappointment analyses revealed that providers failed statistically to meet patients' predisposed expectations in all three settings.

Conclusions Overall, most respondents' predisposed expectations were unmet during their interaction with an audiologist. These expectations differed across professional settings, with the greatest unmet expectations observed in the rehabilitative and medical settings. Patient readiness is influenced by the behavior of the provider which, at present, appears to be a barrier to patients' acceptance of treatment options.

An ecological settlement design for refugees in Kocaeli
Authors: Küçük Merve , Karadayi Tulay Tikansak
Published: July 2020

After the civil war in Syria, many refugees sought refuge to Turkey. It brought along many environmental problems such as sudden population growth and resource shortage. It is thought to design an ecological settlement that can produce its own energy and be self-sufficient as a solution due to the limited natural resources, in order to meet the need for shelter quickly in emergency situations. With this in mind, in order to create an ecological settlement, a sample and literature search was conducted and sustainable ecological settlement criteria were determined. As a place operation, the position is preferred in Turkey and that provides employment and by day increasing the number of refugees residing Kocaeli been selected. In line with the ecological settlement criteria, a survey was conducted to understand the accommodation problems and environmental awareness of Syrian refugees living in Kocaeli. Ecological living units are designed in line with the environmental, climatic and sociological data obtained. The units are placed in accordance with the physical environmental conditions of the plot chosen for ecological settlement. In the conclusion part, the applicability of the designed project has been evaluated in line with economic, sociological and ecological criteria and its positive and negative aspects have been discussed.

In the sample area selected in this study, it is aimed to create an ecological residential area that provides energy, water and raw material conservation in accordance with environmental data, protects the ecosystem, and provides adequate comfort conditions for the users indoors. This study is intended to be a source for ecological settlement projects in order to create livelihoods for low-income groups and to stimulate agriculture, except in emergencies.
EU Cohesion Policy Performance: Measures and Regional Variation
Authors: Moreno Rosina
Published: July 2020

The main objective of this paper is to describe the performance of the EU Cohesion Policy in terms of EU funds effectiveness. The effectiveness in the absorption of funds is a permanent challenge for EU member states, and therefore, the analysis of the absorption capacity is needed in its different spheres: its scope, its determinants and its effects. The present paper deals with the first one, the scope of the absorption of EU resources and focus on an aspect that has been widely forgotten so far: the regional variation in the absorption of the structural funds. Based on EU regional aggregate data on funds commitment and absorption provided by the European Commission for the Operating Program 2007-2013 at the NUTS2 level, we observe thatfull absorption was more the exception than the rule, with an important regional variation. In addition, we offer a discussion on how lack of timely available regional data on EU fund payments hinders the analysis of the effectiveness of the regional absorption of the funds.
Understanding the process of creation of European identity – the role of Cohesion Policy. A review.
Authors: Royuela Mora Vicente , López-Bazo Enrique
Published: July 2020

This paper reviews the theoretical arguments provided by the extant literature for understanding the process of creation of a European identity. We discuss the grounds of mechanisms and determinants driving citizens’ identification with Europe, stressing the role of the territorial dimension on European identity formation. More precisely, our focus is on the literature that have considered the link between European identity and EU policies that influence the citizens’ socio-economic conditions, in general, and Cohesion Policy in particular. This is a major policy within the EU that accounted for some 350 billion euros in the 2007-2013 programming period, about a third of total EU budget. Consequently, it is expected to determine the way citizens identify with the European project, both in the regions more and less benefited by the policy. The study also considers arguments supporting a sort of urban-rural divide in European identity, which could interact with the influence of the Cohesion Policy. Initial descriptive evidence on these links is provided based on results from a comprehensive survey for 15 EU member states.
On the Fast Propagating Ultra-hot Disturbance Captured by SDO/AIA: An In-depth Insight into the Coronal Nonlinear Dynamics
Authors: Li Hongbo , Feng Hengqiang , Liu Yu , Shen Yuandeng , Tian Zhanjun , Zhao Guoqing , Zhao Ake
Published: July 2020

The impulsive heating events and their corresponding nonlinear dynamics remain one of the most obscure physical processes in solar atmospheric physics. The complicacy of these processes together with limited observations have greatly hampered our understanding of them. Here, we present, for the first time, an unambiguous example of a nonlinear acoustic wave in a closed coronal loop or loop segment, which appeared as a fast propagating ultra-hot disturbance cohesively in an indistinguishable corona loop with a highly evolving emission intensity profile. Based on the theory of propagating nonlinear waves, we argue that this type of observation can provide further information for the disturbance during its propagation. With this information, we conclude that the propagating nonlinear disturbance can quickly heat the corona through the rarefaction wave, and the disturbance-induced magnetic reconnection should not happen in our observation. Besides, a convenient criterion has also been deduced for the existence of the disturbance-induced reconnection mechanism. All of this provides us with a new insight into the accompanying nonlinear dynamics of solar impulsive heating events, which can not only shed light on problems including coronal heating and the fast formation of hot coronal loops, but also show us a very novel and prospective seismology scheme for the diagnosis of coronal plasma properties.
On the Distance of SGR 1935+2154 Associated with FRB 200428 and Hosted in SNR G57.2+0.8
Authors: Zhong Shu-Qing , Dai Zi-Gao , Zhang Hai-Ming , Deng Can-Min
Published: July 2020

Owing to the detection of an extremely bright fast radio burst (FRB) 200428 associated with a hard X-ray counterpart from the magnetar soft gamma-ray repeater (SGR) 1935+2154, the distance of SGR 1935+2154 potentially hosted in the supernova remnant (SNR) G57.2+0.8 can be revisited. Under the assumption that the SGR and the SNR are physically related, in this Letter, by investigating the dispersion measure (DM) of the FRB contributed by the foreground medium of our Galaxy and the local environments and combining other observational constraints, we find that the distance of SGR 1935+2154 turns out to be 9.0 ± 2.5 kpc and the SNR radius falls into 10–18 pc since the local DM contribution is as low as 0–18 pc cm−3. These results are basically consistent with previous studies. In addition, an estimate for the Faraday rotation measure of the SGR and SNR is also carried out.

Published: July 2020

BACKGROUND: The term amniotic fluid (AF) can be an ideal alternative as a source of mesenchymal stem cells (MSCs), originating from the neonate. Preclinical studies of the second- and third-trimester amnion fluid cells confirmed the number of potential donors from this wasted material.
AIM: This study aims to look at the forming time of stem cells derived from AF-MSCs.
MATERIALS AND METHODS: AF samples from healthy human donors were collected during full-term C-sections and kept at 4°C until processed. The number of colony-forming unit-fibroblast was assessed microscopically by calculating spindle-shaped colonies that clearly resembled of fibroblasts and did not include colonies with rounded epithelioid morphology. The immunophenotyping of their independent AF preparations was done using the human MSC phenotyping kit which was done according to the manufacturer’s instruction by flow cytometry.
RESULTS: The result showed that it succeeded in getting 8 million cells which will be used for research on pelvic organ prolapse therapy using AF-MSCs. The stem cell isolation totally takes 6 weeks. We got 2 million stem cells in one flask.
CONCLUSION: This study concludes that the time needed for differentiation of AF-MSCs is 6 weeks and AF-MSCs express mesenchymal markers such as CD90, CD73 (SH3, SH), and CD105 (SH2) and these cells also express HLA antigens – ABC, CD 34, and CD 45 which are hematopoietic markers and endothelial CD31 markers.

AIM: To know of effect of ethanolic extract of Pirdot leaves of immunoglobulin G and lysozyme activity in rats treated with Sheep Red Blood Cell (SRBC).
METHODS: Experimental design used in this research was Completely Randomized Design (CRD). There were 24 white rats to be classified into four groups: a control group with water (G0), a group treated with 0.1 ml sheep red blood cell (SRBC) (G1), a group treated with 500 mg/kg ethanol extract pirdot leaves (EES) (G2), and a group treated with 500 mg/KgBW ethanol Extract pirdot leaves (EES) + 0.1 ml SRBC (G3). Immunostimulant activity was evaluated by analyzingthe levels of immunoglobulin G with ELISA method, lysozyme with ABX Micros 60 and histophatology kidney with Hematoxylin-Eosin stainning.
RESULTS: The lysozyme activity in rats were treated with only SRBC () is higher and significantly different compared with a group of control (). Necrosis was not found in a group control () and rats treated EES 500 mg/kg ().There were no significant change in histophatology of kidney in rats treated EES 500 mg/kg. Disruption in bowman space with glomerulus was found in G1 (SRBC). Antigen induced disruption in G1 (SRBC) whereas giving extract ethanolic Pirdot leaves concurrently with antigen SRBC can protect kidney from disruption in G3.
CONCLUSIONS: A significantly effect of immunoglobulin G, lysozyme activity and histophatology kidney in rats after given by ethanolic extract of pirdot leaves.

BACKGROUND: Osteoarthritis (OA) is a degenerative joint disease in one or more joints characterized by changes in pathological structures such as cartilage, hypertrophy, and remodeling of the subchondral bone and secondary inflammation of the synovium membrane, causing changes in joint components such as cells, matrices, and molecular production. At the molecular level, an imbalance between catabolic and anabolic activities in joint cartilage results in OA. Nuclear factor kappa beta (NFκβ) is a cytokine that plays an important role in the signaling pathway of the pathogenesis of OA in causing an inflammatory reaction, whereas interleukin (IL)-10 is an anti-inflammatory cytokine that is involved in the pathogenesis of OA.
AIM: This study aims to prove the influence before and after administration mesenchymal stem cells from Wharton’s jelly on the serum NFκβ and IL-10 levels in OA rat models.
MATERIALS AND METHODS: This research is an experimental study with the design of post-test-only control group design. The sample consisted of 16 OA rats as a control group and 16 OA rats treated with MSC-WJ as a treatment group. OA induction is done by injection of monosodium iodoacetate (MIA) into the intra-articular right knee. Giving MSC-WJ is done in the 3rd week after MIA induction. The serum NFκβ and IL-10 levels were measured after 3 weeks treated with MSC-WJ using the ELISA method. The statistical test used is an independent t-test. p < 0.05 was said to be statistically significant.
RESULTS: From the research results obtained, serum levels of knee OA of rat knee OA treated with mesenchymal stem cell Wharton jelly are lower than serum NFκβ levels of knee OA of the rat that is not treated, but the difference in levels of NFκβ is not significant (p > 0.05). The serum IL-10 level of rat OA of knee treated with mesenchymal stem cell Wharton jelly was higher than the serum IL-10 level of rat OA of the knee that was not treated, difference in levels of IL-10, is significant (p < 0.05).
CONCLUSION: This study concluded that MSC-WJ significantly decreased the serum NFκβ levels of OA rats and not significantly increased the serum IL-10 levels of OA rats.
Determinants of pipe-borne water consumption by urban households in Cameroon
Authors: Totouom Armand
Published: July 2020

Utilisant des données issues d’une enquête réalisée à Douala et Yaoundé, cette étude analyse les déterminants de la consommation en eau des ménages urbains camerounais raccordés au réseau public. Les résultats montrent que le niveau d’éducation, les revenus et les coûts de raccordement au réseau constituent entre autres, des déterminant significatifs de l’accès au réseau. Ils suggèrent également une faible réactivité de la demande en eau aux changements de prix. L’élasticité-prix directe obtenue est de -0,326 avec l’approche des variables instrumentales et de -0,550 avec celle des moindres carrés ordinaires. Les autres déterminants significatifs de la consommation en eau sont le revenu, la taille du ménage, la taille du logement et la redistribution de l’eau au voisinage.

Les modèles de dépendance des ressources, le changement d’objectifs et la valeur sociale dans les organismes à but non lucratif : le changement d’objectifs est-il important dans la gestion des organismes à but non lucratif ?
Authors: Seo JungWook
Published: July 2020

L’acquisition de ressources est un facteur important pour la survie et le succès des organismes à but non lucratif. Les organismes à but non lucratif ne sont pas à l’abri des exigences des bailleurs de fonds potentiels et ils subissent des changements d’objectifs involontaires dans les environnements concurrentiels. Dans le présent article, nous étudions les relations entre les modèles de dépendance aux ressources (dépendance aux ressources, compétitivité des ressources et diversité des ressources), les changements d’objectifs et la valeur sociale dans les organismes à but non lucratif. Les résultats indiquent que la concurrence pour les ressources financières (compétitivité des ressources) est positivement associée au changement d’objectifs dans les organismes à but non lucratif. Le changement d’objectifs dans un environnement marqué par une forte compétitivité des ressources a un effet négatif sur la valeur sociale. D’autre part, les résultats empiriques montrent qu’une structure de revenus diversifiée ou équilibrée (grande diversité des ressources) aide les organismes à but non lucratif à maintenir leur valeur sociale. Remarques à l’intention des praticiens La présente étude montre qu’un changement fréquent d’objectifs peut nuire à la valeur sociale du secteur à but non lucratif. On peut comprendre cela comme le signe que la participation des parties prenantes externes complique la réalisation de la valeur sociale dans la mesure où les exigences des bailleurs de fonds potentiels sont une cause majeure de changement d’objectifs dans les organismes à but non lucratif. Pour remédier à ce problème, les organismes à but non lucratif doivent essayer de réduire leur dépendance à l’égard d’une ou de quelques ressources financières seulement pour assurer leur autonomie et leur valeur sociale. À moyen et à long terme, les organismes à but non lucratif devraient renforcer leur indépendance financière afin d’assurer leur survie et leur succès, ainsi que d’améliorer leur valeur sociale.
A multiple-relaxation-time lattice Boltzmann method with Beam-Warming scheme for a coupled chemotaxis-fluid model
Authors: Qiao Zhonghua , Yang Xuguang
Published: July 2020

In this work, a multiple-relaxation-time (MRT) lattice Boltzmann method (LBM) is proposed to solve a coupled chemotaxis-fluid model. In the evolution equation of the proposed LBM, Beam-Warming (B-W) scheme is used to enhance the numerical stability. In numerical experiments, at first, the comparison between the classical LBM and the present LBM with B-W scheme is carried out by simulating blow up phenomenon of the Keller-Segel (K-S) model. Numerical results show that the stability of the present LBM with B-W scheme is better than the classical one. Then, the second order convergence rate of the proposed B-W scheme is verified in the numerical study of the coupled Navier-Stokes (N-S) K-S model. Finally, through solving the coupled chemotaxis-fluid model, the formation of falling bacterial plumes is numerically investigated. Numerical results agree well with existing ones in the literature.
Recent progress on the mathematical study of anomalous localized resonance in elasticity
Authors: Li Hongjie
Published: July 2020

We consider the anomalous localized resonance induced by negative elastic metamaterials and its application in invisibility cloaking. We survey the recent mathematical developments in the literature and discuss two mathematical strategies that have been developed for tackling this peculiar resonance phenomenon. The first one is the spectral method, which explores the anomalous localized resonance through investigating the spectral system of the associated Neumann-Poincaré operator. The other one is the variational method, which considers the anomalous localized resonance via calculating the nontrivial kernels of a non-elliptic partial differential operator. The advantages and the relationship between the two methods are discussed. Finally, we propose some open problems for the future study.
Strong $ (L^2,L^\gamma\cap H_0^1) $-continuity in initial data of nonlinear reaction-diffusion equation in any space dimension

In this paper we study the continuity in initial data of a classical reaction-diffusion equation with arbitrary $ p>2 $ order nonlinearity and in any space dimension $ N \geqslant 1 $. It is proved that the weak solutions can be $ (L^2, L^\gamma\cap H_0^1) $-continuous in initial data for arbitrarily large $ \gamma \geqslant 2 $ (independent of the physical parameters of the system), i.e., can converge in the norm of any $ L^\gamma\cap H_0^1 $ as the corresponding initial values converge in $ L^2 $. In fact, the system is shown to be $ (L^2, L^\gamma\cap H_0^1) $-smoothing in a H$ \ddot{\rm o} $lder way. Applying this to the global attractor we find that, with external forcing only in $ L^2 $, the attractor $ \mathscr{A} $ attracts bounded subsets of $ L^2 $ in the norm of any $ L^\gamma\cap H_0^1 $, and that every translation set $ \mathscr{A}-z_0 $ of $ \mathscr{A} $ for any $ z_0\in \mathscr{A} $ is a finite dimensional compact subset of $ L^\gamma\cap H_0^1 $. The main technique we employ is a combination of a Moser iteration and a decomposition of the nonlinearity, by which the interpolation inequalities are avoided and the new continuity result is obtained without any restrictions on the order $ p>2 $ of the nonlinearity and the space dimension $ N \geqslant 1 $.
