Sociedade Brasileira de Cefaleia: como tudo começou
Authors: Silva-Néto Raimundo Pereira da
Published: May 2021

A Sociedade Brasileira de Cefaleia (SBCe) foi fundada no dia 19 de maio de 1978 graças ao empenho de Edgard Raffaelli Júnior (1930-2006). Ele foi o pioneiro no estudo da cefaleia na América Latina e dedicou toda a sua vida a essa causa. Tudo começou com 14 médicos e, hoje, a SBCe tem quase 400 membros associados, distribuídos por todas as regiões do País. A partir de 1979, a SBCe passou a organizar uma reunião científica anual (simpósio, curso ou congresso).
Trigeminal neuralgia and persistent idiopathic facial pain
Authors: Obermann Mark , Holle Dagny , Katsarava Zaza
Published: May 2021

Trigeminal neuralgia (TN) and persistent idiopathic facial pain (PIFP) are two of the most puzzling orofacial pain conditions and affected patients often are very difficult to treat. TN is characterized by paroxysms of brief but crucial pain, followed by asymptomatic periods without pain. In some patients a constant dull background pain may persist. This constant dull pain sometimes makes the distinction from PIFP difficult. PIFP is defined as continuous facial pain, typically localized in a circumscribed area of the face, which is not accompanied by any neurological or other lesion identified by clinical examination or clinical investigations. The pain usually does not stay within the usual anatomic boundaries of the trigeminal nerve distribution and is a diagnosis of exclusion. Epidemiologic evidence on TN and even more so on PIFP is quite scarce, but generally both conditions are considered to be rare diseases. The aetiology and underlying pathophysiology of TN and more so PIFP remain unknown. Treatment is based on only few randomized controlled clinical trials and insufficiently evaluated surgical procedures.

Published: May 2021

This study aimed to compare quality of life (QoL) among three groups of forty people each, consisting in a group of migraineurs, a group of diabetics and a group of healthy subjects. The three groups were submitted to the Brazilian version of SF-36, a questionnaire that includes eight domains: physical functioning, limitations due to physical aspects, pain, general health, vitality, social aspects, emotional aspects and mental health. Each item receives a score of 0-100, and patients were grouped into two groups: low QoL (0-60) a good QoL (61-100) points. The presence migraine or diabetes mellitus lead to a decrease in patients QoL that was greater in the migraineurs. The domains that appear to be most affected were physical functioning, limitations due to physical pain and mental health.

In the center of Psychoanalysis and art surrounds points that are related to each other. During this article it will be analyzed a little about history of art and artists, focusing on the writer Leon Tolstoi, in which will be perceived a similar thought between Freud and Tostoi. Later on, there will appear notions of art in the psychoanalytic works of Freud and Lacan. Finally, in the topic implications of art for psychoanalysis, there will be perceptible approximations between such fields of knowledge. Thus, in essence, this entire article intends to update the theoretical, technical and ethical references of how art acts as a source of inspiration for the psychoanalytic clinic

The Determinants of Profitability Large-Scale and Small Scale Turkish Deposit Banks
Authors: Pelin Kaya , Babuşçu Şenol , Hazar Adalet
Published: May 2021

This paper aims to explore the bank-specific and macroeconomic determinants of the banks’ profitability by dividing the Turkish deposit banks into large-scale and small-scale entities. For this purpose, panel data analysis was applied using a fixed effects model, based on quarterly data for the period from March 2009 to September 2020 for 24 deposit banks. Return on assets and return on equity are used as a measure of the banks’ profitability. According to the results, the determinants of profitability differ between large-scale banks and small-scale banks. With respect to the bank-specific determinants, the findings show that the equity/assets, deposits/assets and liquidity ratio have a significant impact on the profitability of large-scale banks, whereas they have no relationship with the profitability of small-scale banks. The profitability of large-scale banks is negatively affected by their asset quality ratios. On the other hand, while the ratio of loans to total assets has no impact on the profitability of small-scale banks, the non-performing loan ratio has a positive impact. While the asset size and income-expense ratios have positive and significant impacts on the profitability of small-scale banks, they exhibit no relationship with the profitability of large-scale banks. With regard to macroeconomic indicators, small-scale banks’ profitability is negatively affected by economic growth, whilst large-scale banks are not. This study is aimed to contribute to the literature by analysing the determinants of Turkish deposit banks’ profitability under the classification of large-scale and small-scale banks.
Examining the perceived reliability of cost effective e-learning handsets for teaching and learning in schools
Authors:   , Sofowora Mayowa A.
Published: May 2021

The use of mobile devices such as cell phones, smartphones, personal digital assistants and tablet computers is becoming prevalent in today’s world; and it is facilitating access to a vast amount of data, services and applications for the improvement of people’s lives. Advances in electronics and manufacturing technologies usually lead to the rapid release of newer and sleeker models with new features and capabilities. These newer models therefore render older models obsolete, and this pushes people to frequently replace their devices. The drawback of such frequent replacements is that a large number of devices are disposed and they end up as e-waste. The fact that e-waste constitutes a major hazard to human health and to the environment is the motivation behind this study whose aim is to examine the factors affecting the perceptions of teachers on the durability of cell phones in the e-learning context. This research aims was achieved through the content analysis of existing literature and through a survey of 67 secondary school teachers from the iLembe and UMgungundlovu district municipalities in the KwaZulu-Natal province of South Africa. The attribution theory was selected as the theoretical framework for this study, and it led to the identification of four independent variables (Demographics, Intention, Knowledge, and Actual use) and of one dependent variable (Perceived Durability). The results of this study indicate that teaching experience and school location are the only two demographics that affect other variables from this research: School location affects cell phone durability, and teaching experience affects cell phone usage intentions. These results also indicate that all the variables of this research are linked except for the relationship between knowledge and perceived durability. One of the recommendations of this study is the proposal of a three year cycle for cell phone renewals in schools mobile learning projects in order to manage e-waste through e-recycling, and this recommendation is based on the finding of this research that teachers believe that cell phones generally lasts between two to three years. The main contribution of this study is to have examined the durability of mobile phones in the e-learning context and this is something new compared to all the studies reviewed by this research.
The development of a framework for blended learning in the delivery of Library and Information Science curricula at South African universities
Authors:   , Rajkoomar Mogiveny
Published: May 2021

The core interest in blended learning lies in the need to provide more engaged learning experiences while recognizing the potential of ICTs which has a profound impact on all aspects of life including the Library and Information Service (LIS) field. This doctoral study was undertaken with the objective of exploring the educational and pedagogical issues in blended learning for the development of a framework for designing and implementing blended learning in the delivery of LIS curricula in South African universities. The target populations for this study included, LIS educators from higher education institutions in South Africa offering LIS education, LIS students from these institutions exposed to blended learning interventions and facilitators of blended learning (individuals in institutional teaching and learning units) from the various institutions offering LIS education and using blended learning. The study adopted a mixed method research approach using a fully mixed dominant status design to explore and understand the phenomenon of blended learning at a more detailed level by using qualitative follow-up data (for example, interviews with LIS educators and institutional facilitators of blended learning and focus group discussions with LIS students) to explain and explore the results of a largely quantitative Web survey. The theoretical framework that underpinned the study involved various learning theories, learning styles as well as blended learning models relating to the higher education environment. The key findings of the study reveal that blended learning remains a complex concept with no clear consensus on the key components that need to be blended, how much of each component to blend and the criteria that are needed for the interventions to be regarded as blended learning. This flexibility, to an extent, allows for institutions to tailor the concept and maximise the potential of blended learning while still being responsive to the diverse student populations at South African higher institutions. The framework for blended learning in the delivery of LIS curricula at South African universities proposed by this study is generated from the theories informing this study; the literature reviewed; existing frameworks for blended learning such as Khan’s octagonal framework and the Community of Inquiry (CoI) framework; the findings of this study; the researcher’s own educational experiences; and, is grounded in the larger field of higher education. The use of blended learning has the potential to transform LIS education and training by encouraging LIS educators to reflect on their teaching and learning practices and to use the proposed framework as a guideline to design and implement pedagogically sound blended learning interventions for LIS education and training.

Abstract. The Pan-Eurasian Experiment (PEEX) Science Plan, released in 2015, addressed a need for a holistic system understanding and outlined the most urgent research needs for sustainable development in the Artic-boreal region. Air quality in China and long-range transport of the atmospheric pollutants was also indicated as one of the most crucial topics of the research agenda. This paper summarizes results obtained during the last five years in the Northern Eurasian region. It also introduces recent observations on the air quality in the urban environments in China. The main regions of interest are the Russian Arctic, Northern Eurasian boreal forests (Siberia) and peatlands and on the mega cities in China. We frame our analysis against research themes introduced in 2015. We summarize recent progress in the understanding of the land – atmosphere – ocean systems feedbacks. Although the scientific knowledge in these regions has increased, there are still gaps in our understanding of large-scale climate-Earth surface interactions and feedbacks. This arises from limitations in research infrastructures and integrative data analyses, hindering a comprehensive system analysis. The fast-changing environment and ecosystem changes driven by climate change, socio-economic activities like the China Silk Road Initiative, and the global trends like urbanization further complicate such analyses. We recognize new topics with an increasing importance in the near future, such as enhancing biological sequestration capacity of greenhouse gases into forests and soils to mitigate the climate change and the socio-economic development to tackle air quality issues.
Resolving the ambiguous direction of arrival of weak meteor radar trail echoes
Authors: Kastinen Daniel , Kero Johan , Kozlovsky Alexander , Lester Mark
Published: May 2021

Abstract. Meteor phenomena cause ionized plasmas that can be roughly divided into two distinctly different regimes: a dense and transient plasma region co-moving with the ablating meteoroid and a trail of diffusing plasma left in the atmosphere and moving with the neutral wind. Interferometric radar systems are used to observe the meteor trails and determine their positions and drift velocities.
Depending on the spatial configuration of the receiving antennas and their individual gain patterns, the voltage response can be the same for several different plane wave directions of arrival (DOAs), thereby making it impossible to determine the correct direction. A low signal-to-noise ratio (SNR) can create the same effect probabilistically even if the system contains no theoretical ambiguities. Such is the case for the standard meteor trail echo data products of the Sodankylä Geophysical Observatory SKiYMET all-sky interferometric meteor radar. Meteor trails drift slowly enough in the atmosphere and allow for temporal integration, while meteor head echo targets move too fast. Temporal integration is a common method to increase the SNR of radar signals. For meteor head echoes, we instead propose to use direct Monte Carlo (DMC) simulations to validate DOA measurements. We have implemented two separate temporal integration methods and applied them to 2222 events measured by the Sodankylä meteor radar to simultaneously test the usefulness of such DMC simulations on cases where temporal integration is possible, validate the temporal integration methods, and resolve the ambiguous SKiYMET data products. The two methods are the temporal integration of the signal spatial correlations and matched-filter integration of the individual radar channel signals. The results are compared to Bayesian inference using the DMC simulations and the standard SkiYMET data products. In the examined data set, ∼ 13 % of the events were indicated as ambiguous. Out of these, ∼ 13 % contained anomalous signals. In ∼ 95 % of all ambiguous cases with a nominal signal, the three methods found one and the same output DOA, which was also listed as one of the ambiguous possibilities in the SkiYMET analysis. In all unambiguous cases, the results from all methods concurred.

Published: May 2021

Abstract. Stratospheric HCl observations are an important
diagnostic for the evaluation of catalytic processes that impact the ozone
layer. We report here in situ balloon-borne observations of HCl employing an
off-axis integrated cavity output spectrometer (OA-ICOS) fitted with a
reinjection mirror. Laboratory assessments demonstrated that the
spectrometer has a 90 % response time of 10 s to changes in HCl and a 30 s precision of 26 pptv. The instrument was deployed alongside an ozone
instrument in August 2018 on a balloon-borne descent between 20–80 hPa
(29–18 km altitude). The observations agreed with nearby satellite
measurements made by the Earth Observing System Microwave Limb Sounder
within 10 % on average. This is the first time that stratospheric
measurements of HCl have been made with ICOS and the first time any cavity-enhanced HCl instrument has been tested in flight.
Ideas and perspectives: Biogeochemistry – some key foci for the future

Published: May 2021

Abstract. Biogeochemistry has an important role to play in many
environmental issues of current concern related to global change and air,
water, and soil quality. However, reliable predictions and tangible
implementation of solutions, offered by biogeochemistry, will need further
integration of disciplines. Here, we refocus on how further developing and
strengthening ties between biology, geology, chemistry, and social sciences
will advance biogeochemistry through (1) better incorporation of mechanisms,
including contemporary evolutionary adaptation, to predict changing
biogeochemical cycles, and (2) implementing new and developing insights from
social sciences to better understand how sustainable and equitable responses
by society are achieved. The challenges for biogeochemists in the 21st
century are formidable and will require both the capacity to respond fast to
pressing issues (e.g., catastrophic weather events and pandemics) and
intense collaboration with government officials, the public, and
internationally funded programs. Keys to success will be the degree to which
biogeochemistry can make biogeochemical knowledge more available to policy
makers and educators about predicting future changes in the biosphere, on
timescales from seasons to centuries, in response to climate change and
other anthropogenic impacts. Biogeochemistry also has a place in
facilitating sustainable and equitable responses by society.
Multi-scale virtual field experience, Grand Ledge, Michigan, USA
Authors: Marshall Madeline S. , Higley Melinda C.
Published: May 2021

Abstract. Field experiences are a critical component of undergraduate geoscience education; however, traditional onsite field experiences are not always practical due to accessibility, and the popularity of alternative modes of learning in higher education is increasing. One way to support student access to field experiences is through virtual field trips, implemented either independently or in conjunction with in-person field trips. We created a virtual field trip (VFT) to Grand Ledge, a regionally important suite of sedimentary outcrops in central lower Michigan, USA. This VFT undertakes all stages of a field project, from question development and detailed observation through data collection to interpretation. The VFT was implemented in undergraduate Sedimentation and Stratigraphy courses at two different liberal arts institutions, with one version of the VFT conducted in-person and the other online. The VFT was presented from a locally hosted website and distributed through an online learning platform. Students completed a series of activities using field data in the form of outcrop photos, virtual 3D models of outcrops and hand samples, and photos of thin sections. Student products included annotated field notes, a stratigraphic column, a collaborative stratigraphic correlation, and a final written reflection. VFT assessment demonstrated that students successfully achieved the inquiry-oriented student learning outcomes and student reflection responses provide anecdotal evidence that the field experience was comparable to field geology onsite. This VFT is an example of successful student learning in an upper-level Sedimentation and Stratigraphy course via virtual field experience with an emphasis on local geology.
Magnetic interference mapping of four types of unmanned aircraft systems intended for aeromagnetic surveying
Authors: Tuck Loughlin E. , Samson Claire , Laliberté Jeremy , Cunningham Michael
Published: May 2021

Abstract. Magnetic interference source identification is a critical preparation step
for magnetometer-mounted unmanned aircraft systems (UAS) used for
high-sensitivity geomagnetic surveying. A magnetic field scanner was built
for mapping the low-frequency interference that is produced by a UAS. It was
used to compare four types of electric-powered UAS capable of carrying an
alkali-vapour magnetometer: (1) a single-motor fixed-wing, (2) a
single-rotor helicopter, (3) a quad-rotor helicopter, and (4) a hexa-rotor
helicopter. The scanner's error was estimated by calculating the
root-mean-square deviation of the background total magnetic intensity over
the mapping duration; averaged values ranged between 3.1 and 7.4 nT. Each
mapping was performed above the UAS with the motor(s) engaged and with the
UAS facing in two orthogonal directions; peak interference intensities
ranged between 21.4 and 574.2 nT. For each system, the interference is a
combination of both ferromagnetic and electrical current sources. Major
sources of interference were identified such as servo(s) and the cables
carrying direct current between the motor battery and the electronic speed
controller. Magnetic intensity profiles were measured at various motor
current draws for each UAS, and a change in intensity was observed for
currents as low as 1 A.
Magnetospheric chaos and dynamical complexity response during storm time disturbance

Published: May 2021

Abstract. In this study, we examine the magnetospheric chaos and dynamical complexity
response to the disturbance storm time (Dst) and solar wind electric
field (VBs) during different categories of geomagnetic storm (minor, moderate and major geomagnetic storm). The time series data of the Dst
and VBs are analysed for a period of 9 years using non-linear
dynamics tools (maximal Lyapunov exponent, MLE; approximate entropy, ApEn;
and delay vector variance, DVV). We found a significant trend between each
non-linear parameter and the categories of geomagnetic storm. The MLE and
ApEn values of the Dst indicate that chaotic and dynamical complexity
responses are high during minor geomagnetic storms, reduce at moderate
geomagnetic storms and decline further during major geomagnetic storms.
However, the MLE and ApEn values obtained from VBs indicate that
chaotic and dynamical complexity responses are high with no significant
difference between the periods that are associated with minor, moderate and
major geomagnetic storms. The test for non-linearity in the Dst time
series during major geomagnetic storm reveals the strongest non-linearity
features. Based on these findings, the dynamical features obtained in the
VBs as input and Dst as output of the magnetospheric system
suggest that the magnetospheric dynamics are non-linear, and the solar wind
dynamics are consistently stochastic in nature.
Seismic imaging across fault systems in the Abitibi greenstone belt – an analysis of pre- and post-stack migration approaches in the Chibougamau area, Quebec, Canada
Authors: Cheraghi Saeid , Malehmir Alireza , Naghizadeh Mostafa , Snyder David , Mathieu Lucie , Bedeaux Pierre
Published: May 2021

Abstract. Two high-resolution seismic reflection profiles acquired
north and south of Chibougamau, located in the northeast of the Abitibi
subprovince of Canada, help understand historic volcanically hosted massive
sulfide (VMS) deposits and hydrothermal Cu–Au mineralization found there.
Major faults crossed by the profiles include the Barlow fault in the north
and the Doda fault and the Guercheville fault in the south, all targets of
this study that seeks to determine spatial relationships with a known metal
endowment in the area. Common-offset DMO corrections and common-offset
pre-stack time migrations (PSTMs) were considered. Irregularities of the
trace midpoint distribution resulting from the crooked geometry of both
profiles and their relative contribution to the DMO and PSTM methods and seismic
illumination were assessed in the context of the complex subsurface
architecture of the area. To scrutinize this contribution, seismic images
were generated for offset ranges of 0–9 km using increments of 3 km.
Migration of out-of-plane reflections used cross-dip element analysis to
accurately estimate the fault dip. The seismic imaging shows the thickening
of the upper-crustal rocks near the fault zones along both profiles. In the
northern seismic reflection section, the key geological structures
identified include the Barlow fault and two diffraction sets imaged within
the fault zone that represent potential targets for future exploration. The
south seismic reflection section shows rather a complicated geometry of two
fault systems. The Guercheville fault observed as a subhorizontal reflector
connects to a steeply dipping reflector. The Doda fault dips subvertical in
the shallow crust but as a steeply dipping reflection set at depth. Nearby
gold showings suggest that these faults may help channel and concentrate
mineralizing fluids.
Detrital zircon provenance record of the Zagros mountain building from the Neotethys obduction to the Arabia-Eurasia collision, NW Zagros fold-thrust belt, Kurdistan region of Iraq
Authors: Koshnaw Renas I. , Schlunegger Fritz , Stockli Daniel F.
Published: May 2021

Abstract. Recognition of new angular unconformity and synthesizing of new detrital zircon U-Pb and (U-Th)/He provenance records, including zircon (U-Th)/(He-Pb) double dating, from the NW Zagros elucidate the basin dynamics of the foreland wedge-top and intermontane units, as well as the tectonic processes in the source terranes in response to different geodynamic phases. In this contribution, we present field observations and detrital zircon provenance data from hinterland basins to reconstruct the basin dynamics and the underlying tectonic controls in the NW Zagros in the Kurdistan region of Iraq. Results reveal that the deposition of the suture zone units of the Red Beds Series (RBS; Suwais Group, Govanda Formation, Merga Group) occurred in an intermontane basin on top of folded Upper Cretaceous units with an angular unconformity. The RBS provenance data point at the Paleogene Walash-Naopurdan-Kamyaran (WNK) arc-related complex as a source area and show substantial decrease of magmatism by ~ 36 Ma, as reflected by the youngest ages peaks. New detrital zircon provenance data from the hinterland wedge-top units of the proto-Zagros foreland basin (the Tanjero, Kolosh, and Gercus Formations) exhibit exclusive derivation from the Upper Cretaceous Neotethys ophiolitic terranes, different from the provenance of the older Lower Cretaceous and Paleozoic units that are dominated by the Paleozoic and Neoproterozoic age spectra. These shifts in provenance between different tectonostratigraphic units argue for sediment route reversal from E to W in response to ophiolite obduction, arrival of the WNK complex and commencement of the continental collision during the late Eocene, followed by deposition of the RBS in the hinterland of the proto-Zagros fold-thrust belt, and paleodrainage connection with the post-collisional Neogene foreland basin.

Published: May 2021

This study examines the impact of cooperative membership on rural income generation. It also analyzes the factors influencing participation in cooperatives among rural households in Southwest, Nigeria. The study was designed to account for selection bias into cooperative organizations. Rural household survey data were used and the estimates were based on both the Probit model and non-parametric propensity score matching method. The findings show that income generated through cooperative membership is approximately 10% higher than those generated by noncooperative members. Empirical estimates of determinants of cooperative membership indicate that years of education, age and land size have significant influences on the decision to join cooperatives.
Paulo Freire e os usos da esperança: um relato de experiência

Se proponen modificaciones al sistema actual de trazabilidad y comercialización de la hacienda gorda destinada a faena cuando se realizan operaciones con base en el rendimiento o “el gancho”, lo que se concreta al reformular los deberes y atribuciones del IPCVA para el control y el seguimiento de los productos. Palabras clave: ganadería bovina, mercados, trazabilidad.AbstractThe aim of this work is to analyze the most important aspects in the sale of the products obtained from cattle breeding and fattening, in order to propose a more efficient traceability system and a method for controlling cattle and carcasses weight, considering all interested parties. From an analytical and empirical perspective, our proposals are based on current merchandising theories and interviews with different industry players (farmers, shippers, industry-related professionals, etc.). We suggest some modifications to the current tracing and merchandising system of the fat cattle destined for slaughter, when operations are based on "yield on the hook". Such modifications imply the reformulation of the duties and powers of the IPCVA (Argentine Beef Promotion Institute) for product control and tracing.Keywords: cattle, markets, traceability. JEL: M39                Contador Público, Profesor en Ciencias  Económicas, Especialista en Gestión Agropecuaria, Magister en Gestión Empresaria, Dictado de posgrados en UNLP y UNNE, JTP en Producción y Comercialización en la Fac. de Cias.

Published: May 2021

El objetivo de este artículo, es verificar la aplicación de las cinco fases del proceso de gestión del conocimiento propuestas por Goldoni y Oliveira (2006). El trabajo se desarrolla a través de un estudio de caso de carácter descriptivo, con un enfoque cualitativo, en el Instituto Nacional de Tecnología Agropecuaria, específicamente en la Oficina de Extensión de Coronel Rosales de Punta Alta, a partir de la recolección de datos por medio de documentos de la institución y de una entrevista semiestructurada. Los resultados obtenidos permiten comprobar que la propuesta de los autores mencionados se aplica al caso estudiado en las etapas de creación, almacenamiento, diseminación y utilización del conocimiento. Sin embargo, los indicadores de la etapa de medición sugeridos no se aplican de forma tan efectiva en la evaluación de cada fase del proceso de gestión del conocimiento, debido al contexto y objetivos de la Oficina de Extensión examinada.
Apostillas sobre la transmisión de Max Weber en la enseñanza de teoría de la organización
Authors: Gonzalez Natalia L.
Published: May 2021

Max Weber es habitualmente presentado en la enseñanza de la teoría de la organización como uno de los precursores de la teoría estructuralista y especialmente como el exponente de la teoría de la burocracia. El aporte y la exposición del autor así como el de otros autores de diversas disciplinas, a la construcción del corpus teórico y empírico de la teoría de la organización, adolece de contexto y de historia. Este artículo pretende sintetizar algunas reflexiones en torno a la acontextualización con la que se presentan en la disciplina del pensamiento administrativo las contribuciones del autor.

El artículo realiza un análisis de la evolución del mercado de fondos de inversión en España con especial atención a la variación del peso relativo de cada vocación inversora en función del contexto económico. Este estudio presenta un análisis descriptivo de la capacidad de supervivencia de los fondos de inversión en España, ofreciendo una nueva perspectiva con el cálculo de las tasas de mortalidad y de reposición. Los resultados nos muestran que el perfil del inversor español ha ido cambiando desde posiciones más conservadoras hacia otras alternativas más arriesgadas o con menor rigidez en cuanto al diseño de su cartera. El artículo destaca por su análisis detallado del mercado de fondos, así como el análisis de tasas que proporcionan información adicional al inversor en cuanto a la mortalidad de los fondos de inversión.

Authors: Menichelli Fernando , Milanesi Gastón
Published: May 2021

La presente investigación busca explorar y describir los cambios operados en las representaciones psíquicas del trabajo de un grupo de internos, insertos en un dispositivo laboral institucional. Es un estudio cualitativo que utiliza como método la historia de vida y la técnica administrada es la entrevista semidirigida. Brinda, además, un aporte a la administración desde un enfoque cualitativo y la aplicación poco usual, en este ámbito de conocimiento, del método historia de vida. Se examinan cinco internos por medio de entrevistas en profundidad en diferentes momentos cronológicos de su inserción en el programa laboral. Los resultados obtenidos brindan elementos a los directivos, o gestores, para la definición y desarrollo de políticas de tratamiento penitenciario como así también elementos valiosos para el desarrollo de prácticas ajustadas en recursos humanos a las diferentes empresas que trabajan con estos grupos.

O estudo tem o objetivo de verificar como está se dando a utilização de indicadores de desempenho à luz das perspectivas do Balanced Scorecard (BSC) no processo decisório, em cooperativas de crédito na cidade de João Pessoa-PB. Foi realizado um estudo multicaso, com abordagem qualitativa. Os dados foram coletados a partir da técnica de entrevista em profundidade com auxílio de questionário e tratados a partir da análise do conteúdo e dispostos em framework. Os resultados mostram que o BSC tem função relevante no processo decisório, sendo utilizada em ações relacionadas à capacitação de colaboradores, redução de custos, captação de novos clientes, oferta de produtos novos e aumento de rentabilidade. Além disso, corrobora com a comunicação de estratégias na organização, sobretudo, integrando e alinhando os processos, como também unindo indicadores estratégicos e vantagem competitiva a partir da combinação de indicadores financeiros e não financeiros.
El mercado cambiario y los contenidos en la prensa: un análisis empírico
Authors: Aromí Daniel
Published: May 2021

Se evalúan vínculos entre la evolución del mercado cambiario argentino y el nivel de atención asignado a este mercado en un medio gráfico durante el período 2002-2012. Las estimaciones indican que mayores valores de los rezagos del índice de atención están asociados a una menor tasa de devaluación esperada y a aumentos en las medidas de volatilidad. Estos vínculos son más intensos en períodos con mayor volatilidad. Más allá de las asociaciones lineales, se documenta que el índice tiene importante capacidad predictiva para el caso de grandes movimientos en el tipo de cambio. La evidencia es consistente con instancias de sobrerreacción del tipo de cambio y de coordinación de acciones en base a señales públicas.
