Parole Activity And Moral Economy In Malaysia
Authors: Bin Yaakob Mohd Huzaini , Bin Hj. Sarifuddin Syamsulang
Published: September 2022

Parole is still newly implemented in Malaysia, and based on previous studies abroad, parole activities are not only able to benefit offenders but also socio-economic activities. The purpose of this research paper is to examine parole activity and its contribution to Malaysia's socio-economic development from a moral and economic perspective. As a primary source, we used the Unpublished Report of the Parole Management Meeting and PBSL, and as a secondary source, we reviewed past study literature. Parole in Malaysia isn't just an opportunity for offenders, but also a benefit for prison management and even socio-economic activities. Places for parole are mainly available through Corporate Smart Internships, which are internships provided by the private sector with a minimum wage.

The Covid-19 pandemic has become a period of crisis that has brought many changes to people's lifestyles. The Covid-19 pandemic makes people afraid of being infected by physical contact in every activity. Lack of research on this topic, so this study aims to find out how the determinants of people in Yogyakarta to pay zakat infaq and or alms online during the Covid-19 pandemic were modified based on previous research. This study examines data from 119 respondents with a sample of people living or domiciled in DI Yogyakarta, having income and being Muslim, and having paid zakat infaq and or alms online which was taken by random sampling which was then tested using SEM-PLS analysis with analytical tools. WarpPLS 7. The results of the analysis show that the perceived risk (PR) variable can affect all variables in the UTAUT 2 model to pay zakat, infaq, and sedekah or alms (ZIS) online, but cannot influence interest or behavioural intention. Then in the analysis to determine interest, the variables of performance expectancy, effort expectancy, social influence, and price value cannot influence people's interest in paying zakat infaq and alms online, while facilitating conditions, hedonic motivation and habit can influence it.

Published: September 2022

This study aimed at preparing a Polish self-report version of the Comprehensive Executive Function Inventory (CEFI), verifying its psychometric properties, and shortening it. The sample included 1109 adolescents aged 12 to 19 attending schools located in a city in eastern Poland. Drawing upon the theoretical background of the CEFI and results presented in its manual, we tested three competing factor structures: a unidimensional, nine-factor, and a bifactor structure to verify the inventory’s construct validity. These analyses did not fully confirm any of the hypothesized models. Moreover, the results did not support the analysis of subscale scores. A shortened nine-item version had satisfactory reliability (⍺ = .778; ω = .779), was unidimensional, and scalarly invariant across gender and age.
Technical note: Use of PM2.5 to CO ratio as an indicator of wildfire smoke in urban areas
Authors: Jaffe Daniel A. , Schnieder Brendan , Inouye Daniel
Published: September 2022

Abstract. Wildfires and their resulting smoke are an increasing
problem in many regions of the world. However, identifying the contribution
of smoke to pollutant loadings in urban regions can be challenging at low
concentrations due to the presence of the usual array of anthropogenic
pollutants. Here we propose a method using the difference in PM2.5 to
CO emission ratios between smoke and typical urban pollution. For temperate
wildfires, the mean emission ratio of PM2.5 to CO is in the
range of 0.14–0.18 g PM2.5 g CO−1, whereas typical urban emissions have a
PM2.5 to CO emissions ratio that is lower by a factor of 2–20.
This gives rise to the possibility of using this ratio as an indicator of
wildfire smoke. We use observations at a regulatory surface monitoring site
in Sparks, NV, for the period of May–September 2018–2021. There were many
smoke-influenced periods from numerous California wildfires that burned
during this period. Using a PM2.5 / CO threshold of 30.0 µgm-3ppm-1, we can split the observations into smoke-influenced
and no-smoke periods. We then develop a Monte Carlo simulation, tuned to
local conditions, to derive a set of PM2.5 / CO values that can
be used to identify smoke influence in urban areas. From the simulation, we
find that a smoke enhancement ratio of 140 µgm-3ppm-1
best fits the observations, which is significantly lower than the ratio
observed in fresh smoke plumes (e.g., 200–300 µgm-3ppm-1).
The most likely explanation for this difference is loss of
PM2.5 during dilution and transport to warmer surface layers.
We find that the PM2.5 / CO ratio in urban areas is an excellent
indicator of smoke and should prove to be useful to identify biomass burning
influence on the policy-relevant concentrations of both PM2.5
and O3. Using the results of our Monte Carlo simulation, this ratio can
also quantify the influence of smoke on urban PM2.5.

Abstract. Dust particles larger than 20 µm in diameter have been
regularly observed to remain airborne during long-range transport. In this
work, we modify the parameterization of the mineral dust cycle in the
GOCART-AFWA dust scheme of WRFV4.2.1 to also include such coarse and giant particles, and we further discuss the underlying misrepresented physical
mechanisms which hamper the model in reproducing adequately the transport of
the coarse and giant mineral particles. The initial particle size
distribution is constrained by observations over desert dust sources.
Furthermore, the Stokes drag coefficient has been updated to account for realistic dust particle sizes (Re < 105). The new code was
applied to simulate dust transport over Cabo Verde in August 2015 (AER-D campaign). Model results are evaluated against airborne dust measurements
and the CALIPSO-LIVAS pure dust product. The results show that the modeled lifetimes of the coarser particles are shorter than those observed. Several
sensitivity runs are performed by reducing artificially the particles'
settling velocities in order to compensate underrepresented mechanisms, such
as the non-spherical aerodynamics, in the relevant parameterization schemes.
Our simulations reveal that particles with diameters of 5.5–17 and
40–100 µm are better represented under the assumption of an 80 % reduction in the settling velocity (UR80), while particles with sizes ranging between 17 and 40 µm are better represented in a 60 %
reduction in settling velocity (UR60) scenario. The overall statistical
analysis indicates that the best agreement with airborne in situ measurements downwind (Cabo Verde) is achieved with a 40 % reduction in settling velocity (UR40). Moreover, the UR80 experiment improves the
representation of the vertical structure of the dust layers as those are
captured by the CALIPSO-LIVAS vertically resolved pure dust observations. The current study highlights the necessity of upgrading the existing model
parameterization schemes of the dust life-cycle components towards improving
the assessment of the dust-related impacts within the Earth–atmosphere system.
Atmospheric visibility inferred from continuous-wave Doppler wind lidar
Authors: Queißer Manuel , Harris Michael , Knoop Steven
Published: September 2022

Abstract. Atmospheric visibility, or meteorological optical range
(MOR), is governed by light extinction by aerosols. State-of-the-art
visibility sensors, such as employed in meteorological observatories and
airports, infer MOR by measuring either transmittance or scattering. While
these sensors yield robust measurements with reasonable accuracy (10 % to 20 %), they measure in situ. MOR from these sensors may thus not be
representative of MOR further away, for example, under conditions with
stratified aerosol types. This includes off-shore sites near the sea surface during conditions with advection fog, sea spray or mist. Elastic backscatter lidar can be used to measure light extinction and has previously
demonstrated to be a powerful method to infer visibility. Lidar can measure
visibility not just near the instrument but also further away (remotely) and
single-ended whilst also being capable of measuring profiles of MOR along atmospheric
slant paths. Continuous-wave (CW) Doppler wind lidar systems make up one of
the most widespread type of elastic backscatter lidar and are typically used in wind resource assessment. Using these existing platforms for remote and single-ended measurement of MOR profiles could allow for new and valuable applications. However, the low-light extinction associated with this type of
lidar excludes the use of the extinction coefficient for MOR retrieval but
leaves the backscatter coefficient as a possible proxy for MOR, though with
an accuracy expected to be inferior to the former method. We analysed
backscatter data from CW wind lidar and co-measured MOR from visibility
sensors from two campaigns (Cabauw, Netherlands, and Pershore, United
Kingdom) and found backscatter from CW wind lidar to be a viable proxy of
MOR if calibrated against a visibility sensor. The expected accuracy of the
method is low and of the order of few kilometres. This means MOR from CW wind
lidar could be used in safety-uncritical problems, such as assessment of
visibility of manmade objects, including wind turbines.
Local and remote climate impacts of future African aerosol emissions
Authors: Wells Christopher D. , Kasoar Matthew , Bellouin Nicolas , Voulgarakis Apostolos
Published: September 2022

Abstract. The potential future trend in African aerosol emissions is uncertain, with a large range found in future scenarios used to drive climate projections. The future climate impact of these emissions is therefore uncertain. Using the Shared Socioeconomic Pathway (SSP) scenarios, transient future experiments were performed with the UK Earth System Model UKESM1, investigating the effect of African emissions following the high emission SSP370 scenario as the rest of the world follows the more sustainable SSP119, relative to a global SSP119 control. This isolates the effect of Africa following a relatively more polluted future emissions pathway. SSP370 sees higher direct anthropogenic aerosol emissions, but lower biomass burning emissions, over Africa. Increased aerosol reduces the local incident surface radiation, causing a local cooling, but the dominance of the black carbon absorption effect remotely from Africa leads to a global warming. The local cooling persists even when including the higher African CO2 emissions under SSP370 than SSP119. Precipitation also exhibits complex changes, with large-scale shifts in the Inter-Tropical Convergence Zone (ITCZ) due to hemispheric asymmetries in the applied forcing, and enhanced local rainfall due to mid-tropospheric instability from BC absorption. These results highlight the importance of future African aerosol emissions for regional and global climate, and the spatial complexity of this climate influence.
On the interest of ground penetrating radar data for the estimation of unsaturated soil parameters

Published: September 2022

Abstract. In this study, the interest of ground penetrating radar (GPR) time-lapse measurements for the estimation of hydrodynamic unsaturated soil parameters is investigated using synthetic infiltration experiments. Water movement and electromagnetic wave propagation in the unsaturated zone are modeled using a one-dimensional hydrogeophysical model. The GPR travel time data are analyzed for different reflectors: a moving reflector (the infiltration wetting front) and three fixed reflectors located at different depths in the soil. Global sensitivity analysis (GSA) is employed to assess the influence of the saturated hydraulic conductivity, the saturated and residual water contents, and the Mualem–van Genuchten shape parameters α and n of the soil on the GPR travel time data of the reflectors. Statistical calibration of the soil parameters is then performed using the Markov chain Monte Carlo (MCMC) method. The impact of the type of reflector (moving or fixed) is then evaluated by analyzing the calibrated model parameters and their confidence intervals for different scenarios. GSA results show that the sensitivities of the moving and fixed reflectors data to the hydrodynamic soil parameters are different whereas the fixed reflectors have similar sensitivities. Results of parameter estimation show that the use of only data from the moving or fixed reflectors does not allow a good identification of all soil parameters. When both data are combined, all soil parameters can be well estimated with narrow confidence intervals.
On the linkage between future Arctic sea ice retreat, Euro-Atlantic circulation regimes and temperature extremes over Europe
Authors: Riebold Johannes , Richling Andy , Ulbrich Uwe , Rust Henning , Semmler Tido , Handorf Dörthe
Published: September 2022

Abstract. The question to what extent Arctic sea ice loss is able to affect atmospheric dynamics and climate extremes over mid-latitudes still remains a highly debated topic. In this study we assess the impact of future Arctic sea ice retreat on occurrence probabilities of wintertime circulation regimes and link these dynamical changes to frequency changes in European winter temperature extremes. For this reason, we analyze ECHAM6 sea ice sensitivity model simulations from the Polar Amplification Intercomparison Project and compare experiments with future sea ice loss prescribed over the entire Arctic, as well as only locally over the Barent/Karasea with a present day reference experiment. We first show how these imposed future Arctic sea ice reductions affect large-scale atmospheric dynamics in terms of occurrence frequency changes of five computed Euro-Atlantic winter circulation regimes. Both sensitivity experiments show similar regime frequency changes, such as more frequent occurrences of a Scandinavian blocking pattern in midwinter under reduced sea ice conditions. Afterwards we demonstrate how the Scandinavian blocking regime, but also a regime that resembles the negative phase of the North Atlantic Oscillation can be linked to favored occurrences of European winter cold extremes. In contrast, winter warm extreme occurrences are typically associated with an anticyclonic regime over the eastern Atlantic and a regime similar to the positive state of the North Atlantic Oscillation. Based on these links between temperature extremes and circulation regimes, as well as on the previously detected regime frequency changes we employ a framework of conditional extreme event attribution. This enables us to decompose sea ice induced frequency changes of European temperature extremes into two different contributions: one term that is related to dynamical changes in regime occurrence frequencies, and another more thermodynamically motivated contribution that assumes fixed atmospheric dynamics in terms of circulation regimes. By employing this decomposition procedure we show how the overall thermodynamical warming effect, but also the previously detected increased Scandinavian blocking pattern frequency under future sea ice reductions can dominate and shape the overall response signal of European cold extremes in midwinter. We also demonstrate how for instance a decreased occurrence frequency of the anticyclonic regime over the eastern Atlantic counteracts the thermodynamical warming response and results in no significant changes in overall January warm extreme occurrences. However, when compared to other characteristics of future climate change, such as the thermodynamical impact of globally increased sea surface temperatures, we argue that the detected effects on European temperature extremes related to Arctic sea ice loss are of secondary relevance.
Water level fluctuations drive bank instability in a hypertidal estuary
Authors: Gasparotto Andrea , Darby Stephen E. , Leyland Julian , Carling Paul A.
Published: September 2022

Abstract. Hypertidal estuaries are very dynamic environments characterised by high tidal ranges (>6 m) that can experience rapid rates of bank retreat. Whilst a large body of work on the processes, rates, patterns and factors driving bank erosion has been undertaken in fluvial environments, the process mechanics affecting the stability of the banks with respect to mass failure in hypertidal settings are not well documented. In this study, the processes and trends leading to bank failure and consequent retreat in hypertidal estuaries are treated within the context of the Severn Estuary (UK) by employing a combination of numerical models and field-based observations. Our results highlight that the periodic fluctuations in water level associated with the hypertidal environment drive regular fluctuations in the hydrostatic pressure exerted on the incipient failure surfaces that range from a confinement pressure of 0 kPa (at low tide) to ~100 kPa (at high tide). However, the relatively low transmissivity of the fine-grained banks (that are typical of estuarine environments) results in low seepage inflow/outflow velocities (~3x10-10 m s-1), such that variations in positive pore water pressures within the saturated bank are smaller, ranging between about 10 kPa (at low tide) to ~43 kPa (at high tides). This imbalance in the resisting (hydrostatic confinement) versus driving (positive pore water pressures) forces thereby drives a frequent oscillation of bank stability between stable (at high tide) and unstable states (at low tide). This transition between stability and instability is found not only on a semidiurnal basis, but also on a longer timeframe. In the spring to neaps transitional period, banks experience the coexistence of high degrees of saturation due to the high spring tides and decreasing confinement pressures favoured by the still moderately high channel water levels. This transitional period creates conditions when failures are more likely to occur.
HESS Opinions: Participatory Digital eARth Twin Hydrology systems (DARTHs) for everyone – a blueprint for hydrologists
Authors: Rigon Riccardo , Formetta Giuseppe , Bancheri Marialaura , Tubini Niccolò , D'Amato Concetta , David Olaf , Massari Christian
Published: September 2022

Abstract. The “Digital Earth” (DE) metaphor is very useful for both end users and hydrological modelers (i.e., the coders). In this opinion paper, we analyze different categories of models with the view of making them part of Digital eARth Twin Hydrology systems (DARTHs). We stress the idea that DARTHs are not models, rather they are an appropriate infrastructure that hosts (certain types of) models and provides some basic services for connecting to input data. We also argue that a modeling-by-component strategy is the right one for accomplishing the requirements of the DE.
Five technological steps are envisioned to move from the current state of the art of modeling. In step 1, models are decomposed into interacting modules with, for instance, the agnostic parts dealing with inputs and outputs separated from the model-specific parts that contain the algorithms. In steps 2 to 4, the appropriate software layers are added to gain transparent model execution in the cloud, independently of the hardware and the operating system of computer, without human intervention. Finally, step 5 allows models to be selected as if they were interchangeable with others without giving deceptive answers. This step includes the use of hypothesis testing, the inclusion of error of estimates, the adoption of literate programming and guidelines to obtain informative clean code. The urgency for DARTHs to be open source is supported here in light of the open-science movement and its ideas. Therefore, it is argued that DARTHs must promote a new participatory way of performing hydrological science, in which researchers can contribute cooperatively to characterize and control model outcomes in various territories. Finally, three enabling technologies are also discussed in the context of DARTHs – Earth observations (EOs), high-performance computing (HPC) and machine learning (ML) – as well as how these technologies can be integrated in the overall system to both boost the research activity of scientists and generate knowledge.

Abstract. NMR-based analysis of metabolite mixtures provides crucial
information on biological systems but mostly relies on 1D 1H
experiments for maximizing sensitivity. However, strong peak overlap of
1H spectra often is a limitation for the analysis of inherently complex biological mixtures. Dissolution dynamic nuclear polarization (d-DNP) improves NMR sensitivity by several orders of magnitude, which enables 13C NMR-based analysis of metabolites at natural abundance. We have recently demonstrated the successful introduction of d-DNP into a full
untargeted metabolomics workflow applied to the study of plant metabolism.
Here we describe the systematic optimization of d-DNP experimental settings
for experiments at natural 13C abundance and show how the resolution,
sensitivity, and ultimately the number of detectable signals improve as a
result. We have systematically optimized the parameters involved (in a
semi-automated prototype d-DNP system, from sample preparation to signal
detection, aiming at providing an optimization guide for potential users of
such a system, who may not be experts in instrumental development). The
optimization procedure makes it possible to detect previously inaccessible
protonated 13C signals of metabolites at natural abundance with at
least 4 times improved line shape and a high repeatability compared to a
previously reported d-DNP-enhanced untargeted metabolomic study. This
extends the application scope of hyperpolarized 13C NMR at natural
abundance and paves the way to a more general use of DNP-hyperpolarized NMR
in metabolomics studies.
Baltic Sea freshwater content

Published: September 2022

Abstract. The Baltic Sea is a brackish shallow sea, the state of which is determined by the mixing of the freshwater from net precipitation and runoff with the salty water from the North Sea inflows. The climatological freshwater content is calculated from the Copernicus regional reanalysis. The seasonal freshwater content reflects the specific hydrophysical conditions of each sub-basin, with northern basins being influenced by the seasonal runoff and ice formation the southern basins are more responsive to subsurface salinity changes. The total freshwater content in the Baltic Sea shows steady decrease over the past two decades with a linear trend of 23.9 km3 per year, however the trend has significant spatial variability. In the northern Baltic the freshwater content is influenced by the increase of runoff and decrease of ice formation, which results in positive freshwater content tendencies, while in the southern parts the salty water supply has reduced the freshwater content.
Topology-Preserving Simplification of OpenStreetMap Network Data for Large-scale Simulation in SUMO

Published: September 2022

Converting OpenStreetMap (OSM) data to a road network suitable for microscopic traffic simulation keeps being a challenging task: both missing information and excessive details, as well as wrong typologies present in the dataset frequently confuses automatic converters. In this paper, we present a method along with a reference implementation, Traffic Simulation Map Maker (TSMM), which aims at substantially increasing the automation level of road network prototyping by simplifying the OSM data while preserving important topology information. The main objective of this work is to enable the study of traffic simulation dynamics at scale using real-world road networks, while minimizing the need for solving the long tail of problems related to the road network generation. Our proposed approach yields what we believe is a good trade-off between precision and automation, making bold yet acceptable decisions that solve most of the errors at the source, i.e., the map. While there is definitely a loss in fidelity with respect to the real world, many properties of the road network are preserved. We argue that TSMM greatly improves the availability of arbitrarily large and usable road networks on top of available OSM maps by reducing the complexity for conversion tools and traffic simulation researchers alike. A proof-of-concept study using OSM data from Binjiang, China, demonstrates that TSMM is able to generate a road network with well-preserved topological information which avoids the many errors and deadlocks that occur when building the network using the original input sources.
Simulating platooned connected autonomous vehicle in a large scale urban scenario
Authors: Schweizer Joerg , Poliziani Cristian , Rupi Federico
Published: September 2022

This article is concerned with the performance evaluation of connected, autonomous vehicles (CAVs) in a realistic large-scale microsimulation scenario. In particular the question is: how much could a high diffusion of CAVs possibly change (1)~the average travel speeds (2)~the trip times of all traffic participants, including pedestrians, and (3)~the energy/fuel consumption? For this purpose, admittedly favourable assumptions are made: a 100\% diffusion of platooning-capable CAVs as substitution for private cars as well as a high maximum speed of platooned vehiclesin order to enable platoon formation. The morning rush hour scenario of the metropolitan area of Bologna, Italy has been selected for assessment. This scenario, which has been created and validated in previous works, represents an activity based demand model with travel plans for individual citizens, including all relevant transport modes.  The microsimulation is performed by means of the SUMO simulator. The entire demand has been generated with the SUMOPy tool. For the platooning of CAVs, SUMO's SIMPLA module has been used, which controlls the vehicles via the interactive TRACI API. Results show an increased speed and reduced travel time for CAV vehicles, with respect to human driven cars, in particular in the periphery and less in the center with a dense road network.  However, the reason for improved speeds and travel times is predominantly the higher maximum speed  allowed for vehicles trying to catch up and join a platoon. Furthermore these higher speed would also be resposible for an increase in fuel consumption of approximately 5\%. In conclusion, CAVs alone are unlikely to reduce congestion in an urban area. To make the platooning concept work, additional technology and infrastructure is required in order to merge platoons effectively at freeways and at traffic lights. The latter could be simulated with GLOSA.

Os processos de separação que envolvem as membranas cerâmicas têm apresentado elevado potencial de aplicações em diversos setores industriais. Atualmente, a principal preocupação no desenvolvimento das mesmas é a minimização dos custos e a obtenção de processos de produção mais eficientes. Neste trabalho foram produzidas membranas cerâmicas via compactação a seco uniaxial utilizando matéria-prima de baixo custo e baixa temperatura de sinterização (650 oC) com o objetivo de reduzir o custo de preparação. As membranas foram preparadas a partir da argila chocobofe, concentrado de magnesita e resíduo de granito. As matérias primas foram caracterizadas por difração de raios X, Espectrofotometria de Raios X, Energia Dispersiva e análise termogravimétrica. Foram realizados testes de resistência mecânica, porosidade, além da caracterização por DRX das membranas cerâmicas de baixo custo. O comportamento da membrana foi avaliado por medidas de fluxo de água pura em sistema de escala de bancada, utilizando um módulo de aço inox nas seguintes condições: Pressão 1, 2 e 3 bar, Temperatura de 25 °C e tempo de 60 minutos. As imagens obtidas por MEV da membrana mostraram que o método utilizado para a síntese da membrana de baixo custo foi eficaz, uma vez que mostrou a formação de uma superfície homogênea sem fissuras ou defeitos na superfície da membrana.

Objectives This study was conducted to evaluate the utilisation of antihypertensive agents, assess prescribing adherence and determine the relationship between guideline adherence indicator (GAI) and clinical outcomes among hypertensive CKD patients.  Methods This was a retrospective cohort study involving newly diagnosed CKD patients undergoing follow-up between January to December 2018 at a tertiary Malaysian hospital. The study subjects were screened and recruited using simple random sampling according to inclusion and exclusion criteria. Clinical data was retrieved from the online medical record (eHis system) using a pre-prepared data collection form.  Results A total of 74 patients were included in this study with mean (SD) age of 66.86 (10.86) years old. The majority were male (n= 39, 52.7%) and Malay (n= 34, 45.9%). The study results showed that CCB was the drug of choice prescribed, while the most commonly prescribed combination therapy was ACEI + beta-blocker + CCB and ACEI + CCB. The overall adherence to the guideline was moderate (mean (SD) GAI score of 76.25 (17.56) %). There was a significant difference in mean GAI score between subjects with controlled and uncontrolled BP (92.86 (11.11) vs 69.23 (14.88), P <0.05).

Background: Sleep related breathing disorders (SRBDs) are disorders caused by a decline or interruption in breathing during sleep and can be complicated by cardiovascular complications. Objective: The aim of this study was to evaluate the impact of chronic intermittent hypoxia and nocturnal hypercapnia on global myocardial performance utilizing different modes of echocardiography in patients with SRBDs. Methods:  This a case control study was conducted on 142 adult subjects who attended to outpatient clinics and Mansoura university sleep center, Egypt during the period study from august 2016 till august 2018. Results: There were statistically significant higher BMI and NC in patients with OSA, OHS groups versus the control group (p<0.001). Comparing OSA& OHS  groups with control group, statistically significant difference regarding each of MPI, GLS, TAPSE (mm) and grade of DD by TDI (p<0.05), GLS, TAPSE (mm) and grade of DD by TDI respectively. Speckle tracking echocardiography showed statistically significant differences all over the 17 segment of the LV and the most affected segments are Inferolateral, Inferior and Inferoseptal and showed that basal segments more affected than mid and apical segments.Conclusion: there is cardiovascular comorbidity associated with chronic intermittent hypoxia and nocturnal hypercapnia in patients with OSA and OHS.

El estilo de inserción laboral de las mujeres salvadoreñas: patriarcado, división sexual del trabajo y discriminación.
Authors: Lara López Edgar
Published: September 2022

El autor considera que este artículo constituye un esfuerzo por reflexionar sobre el estilo de inserción laboral de las mujeres salvadoreñas. El autor plantea que los dos factores que condicionan tal estilo es, por un lado, la división sexual del trabajo, y por otro, el proceso de desvalorización de la fuerza de trabajo femenina. Estos factores son vistos a partir de tres indicadores: tasa de desempleo, participación laboral de las mujeres y brechas salariales.

Authors: Badía Serra Eduardo
Published: September 2022

El autor expone las posiciones de dos filósofos españoles en relación con a categoría de materia: el vasco Xavier Zubiri y el navarro Gustavo Bueno. No se plantea un debate entre ambos, sino cómo cada uno de ellos enfoca su propia concepción. El autor busca provocar el interés de la discusión de este concepto, vital tanto para la filosofía como para la ciencia, y que ha recobrado mucha importancia en el campo de la filosofía de la química, por cuanto sin su consideración no es posible acceder a una visión actual de la realidad.

De la crónica a la novela sin ficción: fabuloso atrevimiento de la palabra humana
Authors: Escobar Froilán
Published: September 2022

Este texto, en apretado recorrido, intenta vislumbrar que la crónica no hace otra cosa que contar historias y que las historias tanto de humanos como de dioses es lo que pervive, lo que queda en la memoria, sea como trabajo periodístico o mitología. Mucho se ha hablado en los posibles porqués. Según Tomás Eloy Martínez, el dato nos asombra pero no nos conmueve. Ahí está el secreto, la diferencia entre el número que da el tamaño del hecho y la palabra que lo cuenta. Ahí está también la razón de que se afirme que se ha producido un segundo boom en Latinoamérica, pues la crónica, nacida con los poetas modernistas a finales del siglo XIX, desemboca en 1937 en L’Éspoir, la primera novela sin ficción, y continúa fluyendo con renovada fuerza creadora en todo el ámbito de nuestros países.
