Objectives: The aim of the study was to compare adductor canal block and femoral nerve block in the
postoperative analgesia of patients undergoing elective arthroscopic knee
surgery with respect to opioid use and Visual Analogue Scale (VAS), which is a
unidimensional measurement of pain intensity. Method:. The study was
designed and conducted prospectively between April 2016 and November 2016 in a
tertiary care hospital but the results were evaluated retrospectively. Prior to
the induction of general anesthesia for knee surgery, (the first) 20
consecutive patients underwent femoral nerve block, and (the second) 20 consecutive
patients received adductor canal block. Patients receiving adductor canal block
for analgesia were referred to as Group A and patients receiving femoral nerve
block for analgesia were defined as Group F. Pain was evaluated using the VAS
score.The results were compared statistically. Results: Both the femoral
nerve block and adductor canal block groups showed similar results in terms of
VAS and opioid use (p < 0.05). Conclusion: In the postoperative analgesia of patients undergoing elective arthroscopic knee
surgery, no difference was found between adductor canal block and femoral nerve
block in terms of opioid use and VAS scores.

Published: June 2018

Objectives: The
severity of inflammation occurring during chronic obstructive pulmonary disease
(COPD) is closely associated with oxidative stress. The aim of this study was
to investigate the diagnostic value of Thiol/disulphide homeostasis (TDH) and
ischemia modified albumin (IMA) levels in evaluating oxidative stress in COPD
patients. Methods: This
prospective study was performed with COPD patients presenting to the Kırıkkale
University Hospital and with healthy volunteers. Subjects’ demographic data
(age, sex, body mass index, and smoking status), native thiol (NT), total thiol
(TT), disulphide (Ds), IMA levels and Ds/NT, Ds/TT and NT/TT ratios were
recorded. Statistical analysis was performed with SPSS 21.0 software. Results: One hundred ninety
subjects were enrolled in the study, 141 COPD patients and 49 healthy
volunteers. No difference was determined between the patient and control groups
in terms of age, sex or body mass index. The antioxidant markers; NT and TT
levels and NT/TT ratio were significantly lower in the patient group compared
to the control group (p < 0.001, p < 0.001, and p
< 0.003, respectively). The oxidant markers; IMA levels and Ds/NT and Ds/TT
ratios were significantly higher in the patient group (p = 0.006, p
= 0.003, and p = 0.003, respectively). Significant negative correlation
was determined between antioxidant and oxidant parameters. Sensitivity values
were NT: 87.2%, TT: 83.3%, Ds/NT ratio: 68.1%, Ds/TT ratio: 68.1%, and IMA:
77.8%. Conclusions: TDH was
impaired in favor oxidants in COPD patients. TDH parameters and IMA can be used
to monitor oxidative stress emerging in COPD.

Reddedilmeyi kaygıyla bekleme, algılamaya hazır olma ve reddedilmeye karşı aşırı tepki gösterme olarak tanımlanan reddedilme duyarlılığı, bireyin, kişilerarası ilişkilerindeki sosyal ve psikolojik uyumunu etkileyen önemli bir olgu olarak görülmektedir. Reddedilme duyarlılığının bilişsel-duygusal bilgi işleme dinamiğine sahip olduğunu belirten ilgili literatür, aslında anılan duyarlılığın, benliği diğer insanlardan gelebilecek olası retten koruyabilmek amacına yönelik savunucu motivasyonal bir sistem olarak görmektedir. Öte yandan reddedilme duyarlılığının oluşmasındaki en önemli kaynağın ebeveynler olduğu ve bu bağlamda, bağlanma ve ebeveynlik stilleri ile de yakın ilişkide olduğu; aynı zamanda reddedilme duyarlılığının bazı psikopatolojilerle ilişkili olduğu ve en fazla kişinin romantik ilişkilerini etkilediği belirtilmektedir. Bu noktalardan hareketle, bu gözden geçirme yazısında, kişilerarası ilişki başarısının odağında bulunan reddedilme duyarlılığına yönelik ileride yapılacak olası görgül çalışmalara, yol gösterici olunması amaçlanmıştır.

Published: June 2018

Rasyonel seçim yaklaşımı son yıllarda pek çok disiplinde yaygın olarak kullanılmaya başlanmıştır. nevrozların rasyonel seçim teorisi, hastaların dayanılmaz stres seviyeleri ile karşı karşıya kaldıklarında bilinçli ve kasıtlı olarak nevrotik bozuklukları ortaya çıkardığını savunur. Çarpıcı farklılıklara rağmen, nevrozların rasyonel-seçim teorisi, yeni bir represyon kavramı kullanmakla birlikte Freud’un düşünce çerçevesini sürdürür. Bu yeni teoriye göre, tüm terapiler etkilerini ya hastaların farkındalık yokluğunu ortadan kaldırmak, belirtilerin maliyetini arttırmak, hastanın duygusal sıkıntısını azaltmak ya da stres faktörünü ortadan kaldırmak suretiyle gösterirler. Bu teoride birey stresle ilgili düşünceleri dikkat çekmeden ortadan kaldırmak için bilinçli olarak dikkat dağıtıcı önlemler kullanır ve represyon bilinçli bir başa çıkma mekanizması olarak tanımlanır. Bu makalede rasyonel seçim teorisinin psikiyatride tanımı, bütüncül yaklaşımı, en sık uygulama alanları ve tedavide kullanımını gözden geçirmek amaçlanmıştır.

Effects of structural irregularities on low and mid-rise RC building response
Authors: Bilgin Hüseyin , Uruçi Rezarta
Published: June 2018

During the recent earthquakes, it has been observed that structural irregularities are one of the main reasons of the building damage. Irregularities are weak points in a building which may cause failure of one element or total collapse of the building during an earthquake. Since Albania is a country with moderate seismicity which has been hit by earthquakes of different magnitudes many times establishes the need to study the effect of irregularities is well-founded. The main structural irregularities encountered in Albanian construction practice consist of short column, large and heavy overhangs and soft story. In this study, these types of irregularities are considered in two different types of buildings, low and mid-rise reinforced concrete frame buildings represented by 3- and 6- story respectively. Pushover analyses are deployed to get the effect of structural irregularities on RC building response. A building set is chosen to represent the existing construction practice in the region; regular framed building and buildings with irregularities such as soft stories, short columns, heavy overhangs and the presence of soft story with heavy overhangs. The analyses have been conducted by using ETABS and Seismosoft software. Pushover curves of building set are determined by nonlinear static analysis in two orthogonal directions. Comparative performance evaluations are done by considering EC8 and Albanian Seismic codes (KTP-N2-89). From the obtained results, it is observed that low and mid-rise structures with soft story- two sided overhangs and short column are more vulnerable during earthquakes.
Performance based study on the seismic safety of buildings
Authors: Çelik Zinnur , Budak Ahmet
Published: June 2018

In the scope of this study, information has been provided on the Static Pushover Analysis which is a nonlinear deformation controlled analysis method and the Capacity Spectrum Method used to determine the performance point. In this study, static pushover analysis was made on a six-storey building with reinforcement concrete frame system by changing the materials, steel rebars and soil characteristics. The building’s capacity curves were drawn and decided according to different concrete and reinforcement groups. Furthermore the performance points of different classes of concrete were studied according to three seismic effect levels. In the case of a decrease in the reinforcement strength, a decrease of approximately 30% occurs in the base shear force. If the concrete strength is increased, an increase of 11% occurred in the base shear force. Consequently, in the comparisons made with five different concrete groups and two different reinforcement groups, rather than the increase in the strength of the concrete, an increase in the reinforcement strength was observed to be more effective on the structural capacity. Furthermore, local soil classifications were observed to be the most significant point regarding peak displacement.
Use of geosynthetics to reduce the required right-of-way for roadways and railways
Authors: Bezgin Niyazi Özgür
Published: June 2018

Roadway and railway routes require a right-of-way (ROW) to provide the necessary width for the required travelled way, drainage and earthwork. Correct understanding of ROW along a route is necessary in order to establish a correct width for the intended transportation corridor. Availability of land becomes scarce and cost of land increases in urban zones. Therefore, the costs of establishing a ROW in rural areas and in urban areas are not the same. Earthworks are an important component of route establishment. The required excavations and fills necessitate the use of proper side slopes for the stability of the excavation or the fill. These side slopes directly relate to the mechanical properties of the soil and the depth of the earthwork. This study provides a quantitative and a qualitative understanding of the ROW requirements of roadways and railways and the influence of the earthworks on the determined values of the ROW. The study further investigates the benefits of using geogrids to reduce the necessary ROW for a transportation route through finite element analysis.
Eigenvector and eigenvalue analysis of thick plates resting on elastic foundation with first order finite element
Authors: Özdemir Yaprak Itır
Published: June 2018

The purpose of this paper is to study free vibration analysis of thick plates resting on Winkler foundation using Mindlin’s theory with first order finite element, to determine the effects of the thickness/span ratio, the aspect ratio, subgrade reaction modulus and the boundary conditions on the frequency parameters of thick plates subjected to free vibration. In the analysis, finite element method is used for spatial integration. Finite element formulation of the equations of the thick plate theory is derived by using first order displacement shape functions. A computer program using finite element method is coded in C++ to analyze the plates free, clamped or simply supported along all four edges. In the analysis, 4-noded finite element is used. Graphs are presented that should help engineers in the design of thick plates subjected to earthquake excitations. It is concluded that 4-noded finite element can be effectively used in the free vibration analysis of thick plates. It is also concluded that, in general, the changes in the thickness/span ratio are more effective on the maximum responses considered in this study than the changes in the aspect ratio.

Published: June 2018

Using capacity of cold-formed steel sections increases thanks to the opportunities which are offered by the developing technology. Low production cost and variety of profiles that can be produce easy, fast, high quality provide to improve its popularity as a structural material. In production, Sulphur and Phosphorous accumulation region occurs at intersection region of flanges and web of hot rolled steel profile. This causes to decrease strength of profile. Other difference between cold-formed and hot rolled steel sections is that mechanical properties of steel material homogeneously distributes throughout the profile. Both in frame and truss systems, cold-formed steel profiles develop both as main and secondary bearing element. These present variety options to the designers with pure, galvanized, aluminized applications. As with many building materials, mechanical behavior of cold-formed steel profile is quite complex due to the nature of thin walled steel sections. Design and analysis methods of cold-formed steel profile are rapidly shaped day by day. The general theory of beams investigated in past studies make possible analyses of cold-formed steel profile. Moreover, in structural systems, using of cold-formed steel profile provide height strength besides sustainable, environmentalist, green building because it requires less material and cost. Although these profiles have many advantages, use of cold-formed steel profiles in our country structures is rather limited unfortunately. New steel construction regulations in Turkey also do not mention cold-formed thin walled steel structure. Main purpose of this study reviews structural specifications of cold-formed steel profiles which are applied world-wide.

Published: June 2018

Background: KDM5 enzymes are H3K4 specific histone demethylases involved in transcriptional regulation and DNA repair. These proteins are over-expressed in different kinds of cancer, including breast, prostate and bladder carcinoma, with positive effects on cancer proliferation and chemo-resistance. For these reasons, these enzymes are potential therapeutic cancer targets. Methods: In the present study, we analyzed the effects of three different inhibitors of KDM5 enzymes in MCF-7 breast cancer cells over-expressing JARID1B. In particular we tested H3K4 demethylation (western blot); target gene transcription (RNAseq and real time PCR); radio-sensitivity (citoxicity and clonogenic assays) and damage accumulation (kinetics of H2AX phosphorylation). Results: we show that two compounds with completely different chemical structure can selectively inhibit KDM5 enzymes and that both compounds are capable of increasing sensitivity of breast cancer cells to ionizing radiation and H2AX phosphorylation. Conclusions: These findings confirm the involvement of H3K4 specific demethylases in DNA damage signaling and repair and suggest new strategies for the therapeutic use of their inhibitors.

Published: June 2018

Declining water supply is the main cause of rising water fee for agricultural use. Moreover, in non-technical irrigation, poor irrigation infrastructure exacerbates water scarcity. Thus, the purpose of this study is to identify farmer willingness to pay for non-technical irrigation and its determinants. Structured questionnaire was used to collect data from 100 farmers. Contingent valuation method was employed to elicit farmer WTP and multiple linear regression was used to find its determinants. The result shows that farmer average WTP is Rp 3,055,168 /ha/year. It accounts for 20 percent of total farmer revenue and almost 20 times fee for technical irrigation. Economic and technical variables are the significant determinants of WTP while social variables seem insignificant to WTP. This result indicates high economic value of water, and to improve irrigation management we recommend establishing irrigation infrastructure gradually by mobilizing farmer resources (capital and management) and strengthening WUA.

Published: June 2018

A study is reported on the electrochemical alloying-dealloying properties of Mg2Sn intermetallic compounds. 119Sn Mössbauer spectra of β-Sn powder, thermally alloyed cubic-Mg2Sn and an intermediate MgSn nominal composition are used as references. The discharge of a Mg/micro-Sn half-cell led to significant changes in spectra line shape that are explained by a multiphase mechanism involving the coexistence of c-Mg2Sn, distorted Mg2-δSn and Mg-doped β-Sn. Capacities and capacity retention were improved by using nanoparticulate tin electrodes. This material reduces significantly the diffusion lengths for magnesium and contains surface SnO and SnO2, which are partially electroactive. The half-cell potentials were suitable to be combined versus MgMn2O4 cathodes. Energy density and cycling properties of the resulting full Mg-ion cells are also scrutinized.
Graphene Oxide as Foam Stabilizing Agent for CO2 EOR
Authors: Barrabino Albert , Holt Torleif , Lindeberg Erik
Published: June 2018

Graphene oxide (GO), nanographene oxide (nGO) and partially reduced graphene oxide (rGO) have been studied as possible foam stabilizing agents for CO2 based enhanced oil recovery (EOR). GO was able to stabilize CO2/synthetic sea water foams. rGO was not able to stabilize foams likely due to the high reduction degree of the material. Particle size had a strong influence on foamability and stability. GO hydrophilicity increased as the particle size decreased and no foams were created when particle size was below 1 µm (nGO). GO brine dispersions showed immediate gel formation, which improved foam stability. Particle growth due to layer stacking was also observed. This mechanism was detrimental for foam formation and stabilization. nGO dispersed in synthetic sea water rapidly formed hydrogels and was not filterable. This work indicates that the particles studied are not suitable for CO2 EOR purposes.
Surface Removal of Copper Thin Film under the Ultrathin Water Environment for Nanoscale Process
Authors: Shi Junqin , Peng Weixiang , Chen Juan , Fang Liang , Sun Kun
Published: June 2018

The surface planarity and asperity removal behaviors of atomic scale under the ultrathin water environment was studied for the nanoscale process by molecular dynamics simulation. The monolayer atomic removal was achieved under the noncontact and monoatomic layer contact conditions with different water film thickness, and the newly formed surface is relatively smooth and no deformed layer and plastic defects exist. The nanoscale processing is governed by the interatomic adhering action during which the water film transmits the loading forces to Cu surface and thereby result in the migration and removal of surface atoms. With scratching depth ≥ 0.5 nm, the abrasive particle squeezed out the water film from scratching region and scratched Cu surface directly, leading to the surface quality deterioration mainly governed by the plowing action. This study brings the goals of “0 nm planarity, 0 residual defects and 0 polishing pressure” closer to us in the nanoscale process for the development of ultra-precision manufacture technology.

Published: June 2018

In this systematic survey, an overview of non-conventional and soft-actuators is presented. The review is performed by using well-defined performance criteria with a direction to identify the exemplary applications in robotics. In addition to this, initial guidelines to measure the performance and applicability of soft actuators are provided. The meta-analysis is restricted to four main types of soft actuators: shape memory alloys (SMA), fluidic elastomer actuators (FEA), dielectric electro-activated polymers (DEAP) and shape morphing polymers (SMP). In exploring and comparing the capabilities of these actuators, the focus was on seven different aspects: compliance, topology, scalability-complexity, energy efficiency, operation range, performance and technological readiness level. The overview presented here provides a state-of-the-art summary of the advancements and can help researchers to select the most convenient soft actuators using the comprehensive comparison of the performance criteria.
Overview on Induced Chirality in Magnetic Field Controlled Electro-Deposition and Induced Magnetic Moment Originating from Chiral Electrodes
Authors: Fontanesi Claudio , Kumar Anup , Mondal Prakash
Published: June 2018

Magneto-electrochemistry (MEC) is a unique paradigm in science, where electrochemical experiments are carried out as a function of an applied magnetic field, creating a new horizon of potential scientific and technological applications. Over the time, detailed understanding of this research domain was developed to identify and rationalize the possible effects exerted by a magnetic field on the various microscopic processes occurring in an electrochemical system, such as: electrolyte properties governed by charge-transfer process (electric conductivity, viscosity, and diffusivity), mass transfer, electrochemical kinetics and on the structure/quality of products formed either at the working electrode or in the electrochemical cell. Particularly, magnetic field controlled chiral architecture obtained from deposited metal, alloys and catalyst and their excellent enantio-recognition in experimental frame is highly appealing. Interestingly, Hall effect was also demonstrated in electrolytic medium via an impressive experimental technique which is being employed for further theoretical understanding in the field of magneto-electrochemical science. Later, a highly reproducible local temperature variation was observed in electrochemical electrolytes exposed to perpendicular magnetic and electric fields. However, until recent studies, none of the above mentioned reports considered the possibility of a spin-dependent related charge-transfer process. Recent experimental and theoretical studies reveal that electron’s transmission through chiral molecules is spin-selective and this effect has been referred to as chiral-induced spin-selectivity (CISS) effect. The CISS effect pave the way for the building up of a system characterized by a net magnetic moment exploiting the spin-filtering ability of chiral molecules. This interplay between chirality and magnetism may shed light on fundamental scientific aspects underlying the enantio-recognition and highly efficient electron-transfer that occurs in biological process.
Spectral-Spatial Dimensionality Reduction of APEX Hyperspectral Imagery for Tree Species Classification; a Case Study of Salzach Riparian Mixed Forest
Authors: Dabiri Zahra , Lang Stefan
Published: June 2018

Tree species composition is an important key element for biodiversity and sustainable forest management, and hyperspectral data provide detailed spectral information, which can be used for tree species classification. There are two main challenges for using hyperspectral imagery: a) Hughes phenomena, meaning by increasing the number of bands in hyperspectral imagery, the number of required classification samples would increase exponentially, and b) in a more complex environment, such as riparian mixed forest, focusing on spectral variability per pixel may not be adequate for definability of tree species. Therefore, the focus of this study is to assess spectral-spatial dimensionality reduction of airborne hyperspectral imagery by using minim noise fraction (MNF) transformation, and object-based image analysis (OBIA). An airborne prism experiment (APEX) hyperspectral imagery was used. A study area was a riparian mixed forest located along the Salzach river, and six tree species including Picea abies, Populus (canadensis and balsamifera), Fraxinus excelsior, Alnus incana, and Salix alba were selected. A machine learning algorithm random forest (RF) was used to train and apply a prediction model for classification. Using a spectral dimensionality reduced APEX, a pixel-level classification was also done. According to a confusion matrix, the object-level classification of MNF-derived components achieved the overall accuracy of 85 %, and kappa coefficient of 0.805. The performance of classes according to producer’s accuracy varied between 80% for Fraxinus excelsior, Alnus incana, and Populus canadensis to 90% for Salix alba and Picea abies. Comparison the results to a pixel-level classification, showed a better performance of object-level classification (an overall accuracy of 63% and Kappa coefficient of 0.559 were achieved for pixel-level classification). The performance of classes using pixel-based classification varied 45 % for Alnus incana to 80% for Picea abies. In general, Spectral-spatial complexity reduction using MNF transformation and object-level classification yielded a statistically satisfactory results.

How Methodology Makes Topics: Ageing Immigrants as a Blind Spot in the Migration Research in Austria. A Research Note
Authors: Trummer Ursula , Novak-Zezula Sonja
Published: June 2018

The current research note describes a process where by applying the qualitative method of expert interviews, researchers got confronted with a new topic in their area of expertise that was not on the radar of their research. In the framework of an evaluation study on health promotion interventions for migrants in an urban setting, researchers applied a mixed methods approach. Quantitative element was a self-assessment tool, where providers of health promotion measures described their clientele and rated the quality of their services along given categories. Qualitative element was a series of semi-structured interviews with management and front line service providers. While the self-assessment tool delivered expected results, the interviews revealed an aspect concerning needs and problems of a migrant group researchers had not thought of before. This is the group of immigrants from the 1960ies, coming mainly from Turkey and Former Yugoslavia, now reaching or having reached retirement age. This group was reported as being extremely vulnerable and at risk of a double discrimination as being “old” and “migrant”.

Desk research was conducted in reaction to such data, showing that information on this group is scarce. Given the demographic developments with rising shares of (old) aged immigrants living in Austria, it will be important to improve the respective knowledge base.

equations. We then define minimal models and Liouville theory by
specific axioms on their spectrums and degenerate fields. We solve these
theories by computing three- and four-point functions, and discuss their
existence and uniqueness.
Anstoß e intersubjetividad en la filosofía temprana de J. G. Fichte
Authors: Macedo Rodriguez Gustavo
Published: June 2018

Anstoß e intersubjetividad son dos conceptos fundamentales a partir de los cuales Fichte explica la importancia de la exterioridad en la actividad del yo. En la presente investigación analizo estos dos conceptos centrales en la filosofía temprana de Fichte. Primeramente presento una nueva interpretación del término Anstoß y analizo la relación entre ambos conceptos. Después argumentaré que ambos conceptos forman parte de un proyecto general que consiste en mostrar el carácter holístico de la subjetividad. Se trata, grosso modo, de mostrar la  coherencia y continuidad de estas dos líneas de argumentación a las que remiten los dos conceptos con miras al establecimiento de lo que Fichte mismo llamó “historia prágmática del espíritu humano”. La idea central de este artículo es mostrar que los dos conceptos son complementarios sin contradecirse, formando parte de un proyecto general en Fichte.
Derecho y sanción. La noción de castigo jurídico en Kant y en Hegel
Authors: Elorduy Eduardo Charpenel
Published: June 2018

En este artículo realizo una comparación de las teorías del castigo legal en la filosofía del derecho de Kant y de Hegel. La tesis que busco defender es que, al menos en lo que concierne a este tópico, las posiciones de Kant y de Hegel no deberían leerse en franca oposición, sino como pertenecientes a una familia común de teorías penales retributivistas. El análisis comparativo que presento busca arrojar luz sobre ciertos aspectos estructurales de su filosofía del derecho como un todo y sobre algunas estrategias habituales en ellos en su procedimiento de justificación jurídico-filosófica. La discusión que aquí se presenta mostrará, no obstante, algunas limitaciones de ambas teorías y esbozará a grandes rasgos, a modo de solución a dichas dificultades, una lectura en la cual las concepciones filosóficas de Kant y de Hegel en torno al castigo legal son más bien consideradas como complementarias.
Filosofía sistemática de la libertad Kant y Fichte en comparación crítica
Authors: Zoeller Guenter
Published: June 2018

El presente artículo compara a Kant y a Fichte en la perspectiva doble de identidad y diferencia referida a dos pensadores a quienes une una primera relación de maestro y alumno y a quienes separa una posterior difamación mutua. En el centro de la presentación se encuentra la relación entre espíritu de libertad y forma del sistema que une a Kant y a Fichte más allá de divergencias metódicas y de diferencias doctrinales. La comparación crítica entre Kant y Fichte se desarrollará en cuatro etapas: partirá de la ubicación general de Kant dentro del idealismo alemán y se extenderá a la empresa doble de Kant, expresada de forma crítica, de una doctrina de los principios (“metafísica”) apriorística de naturaleza y libertad, para después ir a la concepción enfáticamente reclamada por Fichte de un “primer sistema de la libertad”  (1992-2012, III/2, 298, 300),[1] y de ahí a las manifestaciones de la libertad en el sistema filosófico de Fichte, teniendo como punto de vista rector el contraste con Kant.[2] Palabras clave: [1] En la forma de citación de la Gesamtausgabe de Fichte se señalará el tomo y el volumen con números romanos y arábigos respectivamente, y después el número de página en cuestión.[2] El presente artículo es parte de un proyecto de carácter más amplio, cuyo tema es la dilucidación del aporte filosófico de Kant y de Fichte; de ahí que se haga continua referencia a publicaciones particulares de mi autoría.
Requisitos patrimoniales y participación política en la obra de John Locke
Authors: Chumbita Joan Severo
Published: June 2018

La relación entre patrimonio y derechos políticos en la obra de John Locke ha sido ampliamente discutida. Por un lado, se encuentran posiciones como las de Kendall y Tully que atribuyen un carácter democrático a la concepción lockeana sobre la sociedad civil. Por otro, interpretaciones como las de Ashcraft que le asignan un sesgo revolucionario e igualitario, próximo a la concepción de los Levellers. Sin embargo, a la luz de una serie de documentos, es posible discutir estas interpretaciones, como ya lo han hecho diversos intérpretes parcialmente (especialmente Wootton, Wood, Vaughn, Marshall, entre otros). Se mostrará aquí que Locke supone que la discusión parlamentaria compete a quienes, representando a los diferentes sectores productivos, discuten la promoción de sus actividades y que los trabajadores, al no disponer de la formación necesaria para la discusión sobre los asuntos públicos, no son considerados para participar del ejercicio parlamentario sino sólo de una resistencia excepcional.
Medicalización, prevención y cuerpos sanos: la actualidad de los aportes de Illich y Foucault
Authors: Aurenque Stephan Diana , De la Ravanal Martín
Published: June 2018

A partir de los análisis de Illich y Foucault se sostiene que el desarrollo de la medicina moderna ocurre paralelo a una cada vez más profunda medicalización que conlleva a importantes cambios en lo que respecta al significado del cuerpo y de la salud. Una de las expresiones actuales más paradigmáticas de estas transformaciones se observa en la medicina preventiva de alta tecnología, en cuanto ella contribuye no sólo a diluir la experiencia subjetiva de enfermedad y sanidad, sino que también dispone al cuerpo para formas sofisticadas de control y poder. El objetivo de este estudio, sin embargo, no es demonizar toda práctica preventiva, sino más bien, denunciar la medicalización como problema creciente y ofrecer elementos teóricos y filosóficos que permitan comprender mejor este fenómeno y develar algunos de sus fundamentos normativos ocultos.
Las nociones de simpatía y de valor en paralelo. El problema de la sociedad pequeña y la sociedad universal en Adam Smith
Authors: Piqué Pilar
Published: June 2018

El presente trabajo se propone mostrar los puntos de contacto existentes entre el desarrollo de la noción de simpatía en La Teoría de los Sentimientos Morales y el desarrollo de la noción de valor en La Riqueza de las Naciones. En cada una de sus dos obras (La Teoría de los Sentimientos Morales y La Riqueza de las Naciones), Smith elige a la noción de simpatía y a la noción de valor como principios fundamentales para la armonía de la conducta social y del sistema de intercambio mercantil, respectivamente. Pero, en ambos casos, esos principios rigen solamente en sociedades pequeñas y no en la sociedad de carácter universal que asomaba ya en la época smithiana, donde el individuo moderno ya no tiene lazos de afecto con todos los miembros de la sociedad y, asimismo, desconoce los esfuerzos necesarios para producir todas las mercancías necesarias para su vida cotidiana.
¿Cómo tratar un “asunto nuevo”? La relación entre la tópica y la crítica en Del método de estudios de nuestro tiempo de Vico
Authors: Brigante Rovida Anna Maria
Published: June 2018

En Del método de estudios de nuestro tiempo, Vico se enfrenta a lo que él llama un asunto nuevo: si es mejor el método de estudios de los antiguos o el de los modernos, representados respectivamente por la tópica y la crítica. Este artículo se propone mostrar el modo como Vico se opone al monismo metodológico en boga en la Nápoles de su tiempo. Tras una primera formulación del verum factum, el napolitano reconfigura el asunto del método en las diferentes ciencias y saberes concentrándose en aquellas que tienen que ver con la conducta humana: la prudencia y la jurisprudencia. Será con respecto a ellas que Vico hará evidente la necesidad de articular los dos métodos de estudios, la tópica y la crítica. Sin embargo, si para la prudencia la tópica determina la crítica, en la jurisprudencia la relación se invierte. Esta inversión determinará el derrotero de la Ciencia nueva.
Disputas definicionales y lenguaje normativo: Cómo discutir acerca de “derechos humanos”
Authors: García Gibson Francisco
Published: June 2018

Las disputas definicionales sobre términos normativos son frecuentes. ¿Vale la pena disputar sobre meras palabras? Sostengo que ganar una disputa definicional tiene efectos prácticos importantes. Imponer una definición particular de un término normativo sobre otros hablantes puede causar en ellos ciertas emociones deseables, o puede influir sobre su interpretación de aquellas reglas jurídicas o morales cuya formulación incluye el término disputado. Luego describo dos modalidades retóricas mediante las cuales los disputantes pueden proponer su definición preferida: una modalidad que presenta la propuesta como si fuera una descripción de un hecho sobre la comunidad lingüística y otra modalidad que presenta la propuesta como una prescripción lingüística. Muestro que debe adoptarse el segundo modo, porque (entre otras razones) es más transparente con respecto a las razones por las cuales disputamos sobre palabras. El trabajo ilustra el punto con el caso de la disputa sobre el término “derechos humanos”.
El sujeto ante la ley Conciencia de la ley moral y Faktum de la razón en Kant
Authors: Gonzalez Vallejos Miguel , Molina Cantó Eduardo
Published: June 2018

En este trabajo analizaré dos aspectos relativos a lo que Kant considera el principio fundamental de la razón práctica. En primer lugar, intentaré mostrar que el principio práctico fundamental implica necesariamente una suerte de suspensión de todo principio subjetivo de acción, esto es, de la función orientadora propia de las máximas. Este sería un primer momento de negatividad inherente a la conciencia de la ley moral en nosotros. En segundo lugar, trataré también de mostrar que la conciencia de dicha ley implica el reconocimiento de nuestra inadecuación originaria respecto de ella, y que dicha inadecuación es sentida necesariamente como un peculiar tipo de dolor, sentimiento negativo tan único y originario como es único y originario el hecho de la conciencia de la ley. Este sería un segundo momento de negatividad, relativo esta vez a la propia identidad práctica del agente.
La “filosofía última” de J.-L. Marion
Authors: Roggero Jorge Luis
Published: June 2018

Este artículo se propone evaluar la apropiación marioniana de las nociones de “ciencia rigurosa” y “filosofía primera”. Marion defiende la necesidad de la primacía de la filosofía, pero propone entenderla como una “filosofía última”. Esta lectura marioniana puede ser iluminada a partir de una comparación con la fenomenología del joven Heidegger.

Görme Yetersizliği Olan ve Olmayan Öğretmenlerin Örgütsel Destek ve Örgütsel Adalet Algıları
Authors: Polat Şule
Published: June 2018

Bu
araştırmada engelli olmayan öğretmenler ve görme engelli öğretmenlerin
görüşlerine bağlı olarak algılanan örgütsel destek ve örgütsel adalet algısı
ilişkisi incelenmiştir. Araştırmanın çalışma grubunu 2016-2017 eğitim öğretim
yılı bahar döneminde görev yapan 154 görme engelli öğretmen ve 278 engelli
olmayan öğretmen oluşturmaktadır. Araştırma verileri “Örgütsel Adalet Algısı
Ölçeği” ve “Örgütsel Destek Ölçeği” ile toplanmıştır. Katılımcılardan toplanan
veriler aritmetik ortalama, standart sapma, t-testi, Anova, doğrulayıcı faktör
analizi (DFA), Pearson korelasyon ve regresyon analizi ile çözümlenmiştir. Sonuç olarak,
çalışma bulguları bir bütün olarak değerlendirildiğinde, öğretmenlerin örgütsel
adalet algısı yaşadıkları; bu örgütsel adalet algısının cinsiyete, mesleki
kıdeme, görme engelli olma ya da engelli olmama durumuna göre ve medeni duruma
göre farklılık göstermemekle birlikte, öğretmenin örgütsel destek algısı
üzerinde etkisi olduğu görülmüştür. Örgütsel desteğin de mesleki kıdem, medeni
duruma, görme engelli olma ya da engelli olmama durumuna göre farklılık
göstermediği buna karşın erkek öğretmenler lehine farklılık gösterdiği tespit
edilmiştir.
