A Swiss Army Knife from the Upper Paleolithic? Experiments on Non-Projectile Uses of Backed Pieces
Authors: Taller Andreas , Taipale Noora
Published: April 2021

Backed lithic artifacts are an important part of the Upper Paleolithic tool kit, and are often among the most abundant categories of lithic tools found at Magdalenian and Gravettian sites. Often these tools are exclusively referred to as projectiles, and indeed many – if not most – backed pieces may have been parts of composite projectile heads, mounted laterally onto organic points (e.g., Allain and Descouts 1957; Allain 1979; Abramova 1982; Bergman and Newcomer 1983; Leroi­ Gourhan 1983; Plisson 1985; Nuzhnyi 1993; Christensen and Valentin 2004; Sano 2009; Langlais 2010; Araujo­Igreja 2011; Tomasso et al. 2018). Experiments of varying comprehensiveness concerned with the use of (Magdalenian) backed pieces as projectile inserts have confirmed the effectivity of this setup (e.g., Moss and Newcomer 1982; Pétillon et al. 2011; Gauvrit Roux et al. 2020). However, backed pieces sometimes also served other purposes like cutting, sawing, shaving, scraping or perforating (Moss and Newcomer 1982; Moss 1983; Owen 1988; Piel­Desruisseaux 1998; Christensen and Valentin 2004; Taller et al. 2012). The modular technological system involving these lithic artifacts is highly versatile, mobile and dynamic as there are numerous possibilities of use and as the small lithic inserts are easy to transport and the composite tools themselves are easy to maintain and repair. Here, we present the results of an experiment where different tasks were carried out using backed pieces hafted in a wooden handle or operated handheld. The design of the handles loosely follows examples found at Canadian Dorset sites where bladelets comparable in size to Magdalenian backed pieces were hafted and used as knives (Owen 1988, 88ff.). We tried out the tools in various activities (cutting, perforating and carving/whittling) on a set of worked materials (wood, antler, marine shell, smoked meat, dried, semi­tanned hide, and tanned leather). After the completion of these tasks, the applicability, durability and usefulness of the setup were evaluated and the lithic inserts were checked microscopically for use­wear traces.

Published: April 2021

En mayo de 1973, Ernesto Volkening recibió de Nicolás Gómez Dávila un legajo con los textos inéditos que fueron publicados cuatro años de implícito. “Inicio la lectura de los Escolios hoy, el día 24 de mayo de 1973 —escribió Volkening—. Y a un tiempo empiezo a tomar los apuntes con los cuales me propongo llenar este cuaderno, y tal vez otros.” A los pocos meses Volkening le presentó a Gómez Dávila los cinco cuadernos en que transcribió y comentó los escolios que despertaron con más fuerza su interés. La presente edición, que consta de dos volúmenes, recoge el texto íntegro de los cinco cuadernos, respetando la disposición del original, e incluye una comparación exhaustiva de los escolios transcritos en los cuadernos con los que se publicaron posteriormente en la primera edición de Colcultura (1977). Puesto que varios de los escolios que Volkening transcribió son inéditos o presentan divergencias importantes con respecto a los que luego pasaron a imprenta, estos cuadernos no solo revelan el agudo intelectual que fue Ernesto Volkening sino que son una ventana privilegiada al taller de escritura del maestro aforista Nicolás Gómez Dávila.

The Healthcare sector is growing leaps and bound, so is its data and information. Security and privacy of this Information has become a crucial issue for this proliferating healthcare industry. In this fast moving global scenario, patients need not carry their medical records in a big bag on move, as in this digital world ,all that patients have to do is to get admitted in a hospital for the treatment , rest all is in hands of Information Assets Infrastructure of these mushrooming hospitals. But due to the increased use of patientâ€™s information sharing among doctors, vis hospitals ;patients and their families raise an issue for security of their medical data and records. Hence improving the Information Security Management Systems (ISMS) has become the necessity to keep secure digital patient records for success of hospitals and their brands or at large name and fame of Healthcare Industry. Patients are required to share information with doctors for correct diagnosis and treatment. Security concerns arise, in transmitting and processing electronic medical records, personal healthcare records, patientsâ€™ billing records as well as public health alerts across many parties with varying security, privacy and trust levels. Not all hospitals adopt all the essential security measures. In the present paper, we are studying eight International Hospitals to review their Information Security Management Systems (ISMS) standards , concluding their stands on the basis of proposed five principles and also proposing the future scope of implementation of IS in the hospital. We contemplate an Information Security model based on the proposed five principles of Information Security.
DESIGN OF AN EFFICIENT METHOD FOR MULTIRESOLUTION WATERMARKING ALGORITHM TO IMPROVE THE ROBUSTNESS
Authors: Ganesh R. , Kannan S. Thabasu
Published: April 2021

Now-a-days watermarking plays a pivotal role in most of the industries for providing security to their own as well as hired or leased data. This paper its main aim is to study the multiresolution watermarking algorithms and also choosing the effective and efficient one for improving the resistance in data compression. Computational savings from such a multiresolution watermarking framework is obvious. The multiresolutional property makes our watermarking scheme robust to image/video down sampling operation by a power of two in either space or time. There is no common framework for multiresolutional digital watermarking of both images and video. A multiresolution watermarking based on the wavelet transformation is selected in each frequency band of the Discrete Wavelet Transform (DWT) domain and therefore it can resist the destruction of image processing. The rapid development of Internet introduces a new set of challenging problems regarding security. One of the most significant problems is to prevent unauthorized copying of digital production from distribution. Digital watermarking has provided a powerful way to claim intellectual protection. We proposed an idea for enhancing the robustness of extracted watermarks. Watermark can be treated as a transmitted signal, while the destruction from attackers is regarded as a noisy distortion in channel. For the implementation, we have used minimum nine coordinate positions. The watermarking algorithms to be taken for this study are Corvi algorithm and Wang algorithm. In all graph, we have plotted X axis as peak signal to noise ratio (PSNR) and y axis as Correlation with original watermark. The threshold value ? is set to 5. The result is smaller than the threshold value then it is feasible, otherwise it is not.

Exploring Sensibility in Modern Indian English Drama
Authors: Parab Vitthal V.
Published: April 2021

The Indian English Drama has developed as an important and versatile body of English Literature and has caught attention of the global audiences. It has made a substantial progress by encapsulating various issues that India has been facing from time to time. It finds its impetus from Indian sensibility, philosophy, myths and religious beliefs and attracted attention of the people beyond boundaries. When one goes through the history of Indian English Drama, one comes to know that it has made a little progress than Indian English Fiction and Poetry. Though Indian English Drama came to the scene before these above-mentioned genres but failed to keep pace with them because of some reasons. Unlike Fiction and Poetry, Drama cannot be restricted to reading only. It needs a theatre, an encouraging audience, effective dialogues, efficient actors and other stagecraft. Indian English Drama passes many phases and at last comes to a whole new range of playwrights who have left no stone unturned to give it its due place. The present paper studies Indian English Drama with all its flaws and highlights the contribution of Modern Indian English Playwrights.

Contribution of Community Based Organizations in the conservation of Volcanoes National Park. â€œCase study of SACOLA in Nyange and Kinigi Sectors, Musanze District, Rwanda.â€
Authors: UWIMANA EUGENE
Published: April 2021

The Community Based Organizations play an important role in the conservation of protected areas. However, they are still at the early stage in Rwanda and require scientific researches to assess their contribution towards National parks conservation. This study was conducted through four cooperatives (Turate ubuhinzi, Ingenzi Kinigi, ANICO, and Muhisimbi) with the sample size of 72 respondents. The data was collected using questionnaires for four months (from July to October 2011) and analyzed using statistical package for social sciences (SPSS), version 16.0. The study was aimed at assessing the contribution of community based organizations to the conservation of Volcanoes National Park, focusing on SACOLA activities in Nyange and Kinigi Sectors, Musanze District. The results indicated that people in the study area conduct many activities but crop production is conducted at 100%. Concerning the activities of SACOLA, the results show that 81.9% of population have already benefited from employment (buffalo wall construction and maintenance, guides in community tourism, porters, etc.). The output from Wilcoxon Signed Ranks Test showed that 55% have decreased their frequencies to go into the park. The same test shows that (11%) respondents have increased their frequencies to enter the park. The study showed also that 33% did not change their attitude towards the use of VNP resources. Referring to the statistical analysis at (p=.000), there is a significance statistical difference between the frequency of going into the park before and after SACOLA activities. There was also an association (P=0.026, Pearson Chi-Square) between satisfaction with SACOLA activities and the probability of going into the park.  From these results, the population is that they are beneficiaries of SACOLA at 100% and they are informed about its activities, and 65.3% recognized to be satisfied at a very high level, while 19.4% of respondents mentioned not to be satisfied. Finally, the results show an improvement in conserving Volcanoes National Park since the creation of SACOLA in 2004, and conclude that the contribution of Community Based Organizations is positive and recommend that more effort is needed to maximize the community involvement and also recommend further researches in the same field.EW
Practice Change and Bricolage in Nursing
Authors: Maniago Jestoni Dulva
Published: April 2021

This paper aimed to define and describe the concepts of practice change and bricolage in nursing. The ontology, epistemology and axiology of practice change in nursing will be clarified as it relates to the experiences of the nurse and patients. This paper proposes that the most significant changes in a nurse-nursed relationship are the self-initiated incremental changes that result in improved patient care, arising from a need to cope with difficult situations, adjust and make sense of the experiences that they were having. It is also within this context that the case is argued for considering that changes in nursing practice involve bricolage activity. Bricolage is the construction or creation of a work from a diverse range of things that happen to be available, or a work created by such a process (Gobbi, 2005). The idea of using patient's environment and available resources which are at hand is the main goal in the bricolage activity (Reed and Shearer, 2011). This stance, which is derived from the work of Levi-Strauss, conceives elements of nursing practice as an embodied, bricolage practice where nurses draw on the 'shards and fragments' of the situation-at-hand to resolve the needs of the individual patient for whom they care. This conceptualization of practice change in nursing could be analyzed with a particular emphasis on its implication for nursing epistemology, pedagogy and praxis.

Az egyéni bűntől a társadalmi felelősségig : Médiabíráskodás Kiss László, az úszóválogatott szövetségi kapitányának nemierőszak-ügyében
Authors: Virágh Enikő Anna
Published: April 2021

A tanulmány a 2016-os Kiss László-ügyet vizsgálja a médiabíráskodás fogalmából kiindulva a legolvasottabb hat online híroldalon megjelenő cikkek alapján, különös tekintettel az újságírói véleménycikkekre. A médiabíráskodás Greer és McLaughlin (2011, 2012) értelmezésében olyan folyamat, amelynek során a hírmédia egyfajta morális alapokra hivatkozó populista igazságszolgáltatást gerjeszt és működtet. A tanulmány egyfelől azt vizsgálja, hogy mennyiben alkalmas a brit média működésére kitalált médiabíráskodás fogalma a magyarországi Kiss László-ügy leírására. Másfelől a nemi erőszak mint az ügy fontos dimenziója is vizsgálat tárgyát képezi, hiszen a Kiss-ügyben egy 55 évvel korábbi, jogilag már lezárt csoportos nemi erőszak elkövetéséről van szó. A tanulmány bemutatja, hogyan épül fel, és miként terjed ki az ügy egyéni szintről intézményi és társadalmi szintre, mi jellemzi a diskurzus eme szintjeit, illetve hogyan működik az egyes szinteken a médiabíráskodás mechanizmusa.

Published: April 2021

The main aim of this report is to identify and describe the idea of digital leadership. For the study, the effects of digital leaders' traits and experience on the digitalization process will be examined. Different multinational and global businesses have been examined to apply the concept of digital leadership to their businesses. In this paper, with the goal of an organizational literature review, we analyze the concept of digital leadership. The paper seeks to identify the digital leadership concept; to analyze these abilities and their impacts deeply in the new digital age. As a result of detailed literature research, digitalization and technological developments lead businesses to transform organizational structures, processes, business models, and strategies. Digital leadership is crucial for organizations to survive in the new digital era by adapting and transforming business strategies. To accomplish business objectives and successfully drive the digital business transformation, digital leaders use and enhance the company's digital assets. Digital leaders have different abilities and perspectives compared to traditional leaders. However, many organizations do not understand digital leaders' value, leading to poor performance and unrecoverable failures. This research paper demonstrates a strong link between digital leadership and corporate success and productivity, following the analysis and clarification of the digital leadership concept generated in the modern age and the review of variable business strategies and positioning of the leadership concept in different sectors.
Maternity Experiences and Perceptions of Emergency Medicine Physicians
Authors: McDonald Lindsey , Illg Zachary , Dow Agata , Gunaga Satheesh
Published: April 2021

INTRODUCTION

Postpartum employment has been recognized as a significant obstacle to breastfeeding continuation rates in the general population. Multiple additional factors can influence emergency medicine (EM) physician mothers’ ability to continue breastfeeding upon return to work. These include the unpredictable nature of emergency room volumes and acuity, absence of protected lactation time or facilities, and varying levels of support from colleagues. This study investigated a sample of female EM physicians’ current perceptions and experiences regarding breastfeeding practices and identified modifiable work-place factors affecting their decision to wean. The authors hypothesized that EM physician mothers would have excellent breastfeeding initiation rates but be largely unable to maintain breastfeeding practices upon returning to work.

METHODS

A 34-item survey questionnaire evaluated demographics, perceptions, and experiences with breastfeeding with a convenience sample of EM attending and resident physicians from two Michigan academic community hospitals.

RESULTS

Thirty-nine surveys were completed, representing a participant response rate of 88.6%. Breastfeeding had been initiated by all respondent mothers, all of whom returned to full-time employment after delivery. Upon return to work, 15 (75%) respondents continued to exclusively breastfeed. The goal of participants was to breastfeed for an average of 7.1 months (± 4.1 months), although the average duration children were exclusively breastfed was 5.8 months (± 4.0 months).

CONCLUSIONS

Based on these results, the reasons for decreased breastfeeding after return to work in an EM residency program setting are multifactorial and include some modifiable interpersonal and institutional influences. These findings support the implementation of work-place strategies and policies to promote successful breastfeeding practices among EM resident and attending physician mothers returning to work.
Analysis of Migrating and Non-Migrating Tides of the Extended Unified Model in the Mesosphere and Lower Thermosphere
Authors: Griffith Matthew J. , Mitchell Nicholas J.
Published: April 2021

Abstract. Atmospheric tides play a key role in coupling the lower, middle and upper atmosphere/ionosphere. The tides reach large amplitudes in the Mesosphere and Lower Thermosphere (MLT) where they can have significant fluxes of energy and momentum and so strongly influence the coupling and dynamics. The tides must therefore be accurately represented in Global Circulation Models (GCMs) that seek to model the coupling of atmospheric layers and impacts on the ionosphere. The tides consist of both migrating (sun-following) and non-migrating (not sun-following) components, both of which have important influences on the atmosphere. The Extended Unified Model (ExUM) is a recently developed version of the Met Office's Unified Model GCM which has been extended to include the MLT. Here, we present the first in-depth analysis of migrating and non-migrating modes in the ExUM. We show that the ExUM produces both non-migrating and migrating tides in the MLT of significant amplitude across a rich spectrum of spatial and temporal modes. The dominant non-migrating modes in the MLT are found to be the DE3, DW2 and DW3 in the diurnal tide and the S0, SW1 and SW3 in the semidiurnal tide. These modes can have monthly mean amplitudes at a height of 95 km as large as 35 ms−1 / 10 K. All the non-migrating modes exhibit a strong seasonal variability in amplitude and significant short-term variability is evident. Both the migrating and non-migrating modes exhibit notable variation with latitude. For example, the temperature and wind diurnal tides maximise at low latitudes and the semidiurnal tides include maxima at high latitudes. Our results demonstrate the capability of the ExUM for modelling atmospheric migrating and non-migrating tides and lays the foundation for its future development into a whole atmosphere model. To this end, we make specific recommendations on further developments which would improve the capability of the model.
Cyanobacteria blooms in the Baltic Sea: a review of models and facts
Authors: Munkes Britta , Löptien Ulrike , Dietze Heiner
Published: April 2021

Abstract. The ecosystem of the Baltic Sea is endangered by eutrophication. This has triggered expensive international management efforts. Some of these efforts are impeded by natural processes such as nitrogen-fixing cyanobacteria blooms that add bioavailable nitrogen to the already over-fertilized system and thereby enhance primary production, export of organic matter to depth, and associated oxygen consumption. Controls of cyanobacteria blooms are not comprehensively understood, and this adds to the uncertainty of model-based projections into the warming future of the Baltic Sea. Here we review our current understanding of cyanobacteria bloom dynamics. We summarize published field studies and laboratory experiments and dissect the basic principles ingrained in state-of-the-art coupled ocean–circulation biogeochemical models.
Effect of rock uplift and Milankovitch timescale variations in precipitation and vegetation cover on catchment erosion rates
Authors: Sharma Hemanti , Ehlers Todd A. , Glotzbach Christoph , Schmid Manuel , Tielbörger Katja
Published: April 2021

Abstract. Catchment erosion and sedimentation are influenced by variations in the rates of rock uplift (tectonics), and periodic fluctuations in climate and vegetation cover. In this study we applied the Landlab-SPACE landscape evolution modelling approach. This study focuses on quantifying the effects changing climate and vegetation on erosion and sedimentation over distinct climate-vegetation settings. As catchment evolution is subjected to tectonic and climate forcings at millennial to million-year time-scales, the simulations are performed over different tectonic scenarios and periodicities of climate-vegetation change. We present a series of generalized experiments that explore the sensitivity of catchment hillslope and fluvial erosion and sedimentation for different rock uplift rates (0.05 mm a−1, 0.1 mm a−1, 0.2 mm a−1) and Milankovitch climate periodicities (23 kyr, 41 kyr and 100 kyr). Model inputs were parameterized for two different climate and vegetation conditions at two sites in the Chilean Coastal Cordillera at ~26° S (arid and sparsely vegetated) and ~33° S (mediterranean). For each setting, steady state topographies were produced for each uplift rate before introducing periodic variations in precipitation and vegetation cover. Following this, the sensitivity of these landscapes was analysed for 3 Myr in a transient state. Results suggest that regardless of the uplift rate, transients in precipitation and vegetation cover resulted in transients in erosion rates in the direction of change in precipitation and vegetation. While the transients in sedimentation were observed to be in the opposite direction of change in the precipitation and vegetation cover, with phase lags of ~1.5–2.5 kyr. These phase lags can be attributed to the changes in plant functional type (PFT) distribution induced by the changes in climatic conditions, which is beyond the scope of this study. These effects being most pronounced over longer period changes (100 kyr) and higher rock uplift rates (0.2 mm yr−1). This holds true for both vegetation and climate settings. Furthermore, transient changes in catchment erosion due to varying vegetation and precipitation were between ~35 %–110 % of the background (rock uplift) rate and are measureable with some techniques (e.g. sediment flux histories, cosmogenic nuclides). Taken together, we find that vegetation-dependent erosion and sedimentation are influenced by Milankovitch timescale changes in climate, but that these transient changes are superimposed upon tectonically driven rates of rock uplift.
Spatiotemporal structure of Baltic free sea level oscillations in barotropic and baroclinic conditions from hydrodynamic modelling
Authors: Zakharchuk Eugeny A. , Tikhonova Natalia , Zakharova Elena , Kouraev Alexei V.
Published: April 2021

Abstract. Free sea level oscillations in barotropic and baroclinic
conditions were examined using numerical experiments based on a 3-D
hydrodynamic model of the Baltic Sea. In a barotropic environment, the
highest amplitudes of free sea level oscillations are observed in the
northern Gulf of Bothnia, eastern Gulf of Finland, and south-western Baltic
Sea. In these areas, the maximum variance appears within the frequency range
corresponding to periods of 13–44 h. In a stratified environment, after the
cessation of meteorological forcing, water masses relax to the equilibrium
state in the form of mesoscale oscillations at the same frequencies as well
as in the form of rapidly decaying low-frequency (seasonal) oscillations.
The total amplitudes of free baroclinic perturbations are significantly
larger than those of barotropic perturbations, reaching 15–17 cm. Contrary
to barotropic, oscillations in baroclinic conditions are strongly pronounced
in the deep-water areas of the Baltic Sea proper. Specific spatial patterns
of amplitudes and phases of free barotropic and baroclinic sea level
oscillations identified them as progressive–standing waves representing
barotropic or baroclinic modes of gravity waves and topographic Rossby
waves.
Simulated Ka- and Ku-band radar altimeter height and freeboard estimation on snow-covered Arctic sea ice
Authors: Tonboe Rasmus T. , Nandan Vishnu , Yackel John , Kern Stefan , Pedersen Leif Toudal , Stroeve Julienne
Published: April 2021

Abstract. Owing to differing and complex snow geophysical properties, radar
waves of different wavelengths undergo variable penetration through
snow-covered sea ice. However, the mechanisms influencing radar altimeter
backscatter from snow-covered sea ice, especially at Ka- and Ku-band
frequencies, and the impact on the Ka- and Ku-band radar scattering horizon
or the “track point” (i.e. the scattering layer depth detected by the radar
re-tracker) are not well understood. In this study, we evaluate the Ka- and
Ku-band radar scattering horizon with respect to radar penetration and ice
floe buoyancy using a first-order scattering model and the Archimedes
principle. The scattering model is forced with snow depth data from the
European Space Agency (ESA) climate change initiative (CCI) round-robin data
package, in which NASA's Operation IceBridge (OIB) data and climatology are
included, and detailed snow geophysical property profiles from the Canadian
Arctic. Our simulations demonstrate that the Ka- and Ku-band track point
difference is a function of snow depth; however, the simulated track point
difference is much smaller than what is reported in the literature from the
Ku-band CryoSat-2 and Ka-band SARAL/AltiKa satellite radar altimeter
observations. We argue that this discrepancy in the Ka- and Ku-band track
point differences is sensitive to ice type and snow depth and its
associated geophysical properties. Snow salinity is first increasing the Ka-
and Ku-band track point difference when the snow is thin and then
decreasing the difference when the snow is thick (>0.1 m). A
relationship between the Ku-band radar scattering horizon and snow depth is
found. This relationship has implications for (1) the use of snow climatology
in the conversion of radar freeboard into sea ice thickness and (2) the
impact of variability in measured snow depth on the derived ice thickness.
For both (1) and (2), the impact of using a snow climatology versus the actual
snow depth is relatively small on the radar freeboard, only raising the
radar freeboard by 0.03 times the climatological snow depth plus 0.03 times
the real snow depth. The radar freeboard is a function of both radar
scattering and floe buoyancy. This study serves to enhance our understanding
of microwave interactions towards improved accuracy of snow depth and sea ice thickness retrievals via the combination of the currently operational and
ESA's forthcoming Ka- and Ku-band dual-frequency CRISTAL radar altimeter
missions.

Tosaka Jun y las funciones epistémicas de la cultura: materiales para un estudio sobre transhistoricidad e identidades colectivas
Authors: Crespín Perales Montserrat
Published: April 2021

La obra del filósofo japonés Tosaka Jun (1900-1945) permanece todavía muy desconocida, tanto en el entramado acotado de los estudios japoneses, como en el campo filosófico. Y esto a pesar de la importancia de sus reflexiones para el ayer al que perteneció y el ahora que se resignifica, en parte, con los materiales residuales del siglo pasado. Dentro de su proyecto filosóficamente polifónico, Tosaka se empeñó en clarificar las relaciones entre nacionalismo cultural, capitalismo, totalitarismo y vida cotidiana. Este trabajo presenta su figura entre lectores y estudiosos de la filosofía hispanohablantes e invita a sopesar críticamente la valía de algunas de sus reflexiones en clave de presente. Para ello se analizarán algunos ejes esenciales de su pensamiento con el propósito de clarificar cómo se cristalizan las nociones culturales, qué engranajes emplean las ideologías reaccionarias para la movilización de la masa social y sus sueños rotos o el mecanismo tras el movimiento de traslación del mundo académico y los medios de comunicación de masas, asuntos que llevarán a una final reflexión sobre la transhistoricidad y la retornada mitologización de las identidades colectivas.
Teleología y lógica en Hegel. Fin y objetividad en los escritos propedéuticos de Nuremberg”.
Authors: Montecinos Fabio Sergio
Published: April 2021

Se determina la posición y función primigenia del concepto de fin (Zweck) en Nuremberg (como final del silogismo y tránsito puro a la idea). Además, se reconstruyen las modificaciones sistemático-arquitectónicas que dieron paso al surgimiento, en la Lógica, de la sección Objetividad y a la consecuente modificación de la posición del fin, que se insertará dentro de ésta como una forma específica de causalidad (finalidad externa), diferenciada de los procesos mecánico-químicos. Con esta modificación, el tránsito del fin a la idea cesa de ser puro, perfilándose específicamente como un momento instrumental del concepto en su proceso de realización en lo objetivo.
El papel de los juicios de percepción y de los conceptos empíricos en la síntesis categorial
Authors: Reyna Fortes Rafael
Published: April 2021

En este trabajo me propongo mostrar, en primer lugar, una interpretación de la distinción kantiana entre juicio de percepción y juicio de experiencia. Posteriormente reconstruiré el proceso de síntesis categorial e intentaré explicar qué papel juegan en dicha acción los conceptos empíricos. En definitiva, la tesis que se va a defender es que en el nivel de constitución de la experiencia tanto los conceptos empíricos como los juicios de percepción hacen posible la síntesis objetiva y, al mismo tiempo, ésta provee a los conceptos involucrados en dicha síntesis, tanto empíricos como puros, sentido y referencia.
A PERFORMANCE DA DOR EM A HORA DA ESTRELA
Authors: SANTOS G. L. A.
Published: April 2021

A crítica a respeito de Clarice Lispector privilegiou uma tendência que se preocupava com a análise do eu e o fluxo de consciência, atrelados tanto a uma leitura psicológica quanto existencialista de sua obra, deixando em evidência o “drama da linguagem” que perpassaria a sua escrita. De fato, essas são marcas que sobressaem nos textos claricianos e parecem ter eclipsado outra faceta fundamental para a compreensão de sua obra: a preocupação com as questões sociais. Neste artigo, propomos uma leitura de A hora da estrela que se preocupa em analisar a obra focando nas críticas sociais e em sua composição estética. Concluímos, à luz da leitura de A partilha do sensível: estética e política, de Jacques Rancière, que o engajamento ético se atrela ao estético, e a obra clariciana é permeada desses encontros de formas bem sutis.

Published: April 2021

Por meio de uma proposta qualitativa de análise, propõe-se uma investigação do seguinte tema: A prática política shakespeariana em Hamlet. O texto comenta os comportamentos e as estratégias políticas da personagem Claudius na peça Hamlet, de William Shakespeare. Articula-se uma compreensão da personagem shakespeariana a um suporte da crítica política à obra O Príncipe, de Nicolau Maquiavel. Compreende-se que esses diálogos apontam para o entendimento da personagem rei Claudius dentro do teatro shakespeariano sob uma perspectiva da construção do caráter do governante e das suas táticas de conservação e sobrevivência das relações de poder que o permitem rei. Discute-se a evolução e a representatividade da função de rei na peça Hamlet, compreendendo-se que o esforço de Claudius em manter-se no poder firma-se em manter-se no poder e em suas tentativas de edificar um caráter de líder para si e para os seus súditos.
