Published: December 2022

El objetivo de este ensayo fue describir las repercusiones sobre los delitos sexuales a menores de edad a través de los medios electrónicos. La metodología que se utilizó en esta investigación fue de carácter descriptiva; el diseño es no experimental de corte transversal. La población investigada agrupó 63 adolescentes con edades de 15 a 18 años. Se utilizó como técnica la encuesta y como instrumento: el cuestionario. Se empleó la Escala de Victimización a través del Teléfono Móvil y de Internet (CYB-VIC) elaborado por Buelga et al. (2012). Se concluye que: las víctimas de abuso sexual pueden ser cualquier niño, niña o adolescente, ya que no existe una característica específica que establezca el perfil de una víctima idónea, esto se refleja en que estos actos se consuman en todas las clases sociales sin distinción del tipo de niveles socioculturales, económicos, y religiosos. El abuso sexual en menores de edad es una experiencia traumática que deja secuelas importantes de una amplia gama de variedad. En general no se puede hablar de un síndrome como tal, ya que la sintomatología siempre variará según los diversos factores que puede influir la manifestación de un síntoma específico, desde aspectos genéticos hasta sociales, familiares y otras experiencias vividas posteriormente. Consecuentemente, la desconfianza por parte de los menores de edad que han sido víctimas de este tipo de situaciones tienen temor de develar esa realidad, así como también se desarrolla la presión por parte de los progenitores o tutores al preocuparse por una presunta situación de abuso, este tipo de cosas provoca que los casos que se descubren aún formen parte de un porcentaje menor, confrontado con el sinnúmero de afectados por esta problemática social que arroja como resultado a un gran número de casos de abuso sexual no revelados en los menores y adolescentes.

Published: December 2022

Ecuador se encuentra posicionado como primer exportador de cacao fino de aroma, representando más del 62% de la producción mundial de este fruto, lo que propicia una abundante disponibilidad de residuos valorizables de esta planta. La composición lignocelulósica de estos residuos les confiere la capacidad de ser procesados y transformados a bioetanol. En esta investigación, los residuos de cáscaras, tallos y hojas de cacao fueron acondicionadas (secadas y pulverizadas) y sometidas a un proceso de sacarificación y fermentación simultánea para la producción de bioetanol de segunda generación. La biomasa acondicionada fue sometida a un pretratamiento de hidrólisis alcalina (NaOH al 3%) con explosión de vapor a 121ºC por 90 min a 1 atm. La biomasa hidrolizada se sometió a un proceso de hidrólisis enzimática empleando la enzima celulasa de Aspergillus niger de Sigma Aldrich y se utilizó simultáneamente la levadura Safale S-04 para la fermentación de los azúcares a bioetanol. Las muestras tratadas fueron filtradas y centrifugadas y el contenido de alcohol se cuantificó mediante cromatografía gaseosa. Las condiciones de sacarificación y fermentación simultánea fueron optimizadas mediante un diseño factorial multinivel, empleando la metodología de superficie de respuesta. El diseño incluyó nueve corridas base (todas por triplicado), donde se evaluaron tres concentraciones enzimáticas (5, 15 y 25 FPU/g) para los cinco gramos de carga inicial de material sólido seco (MSS) y tres temperaturas (27, 37 y 47°C). La maximiza producción de bioetanol (0,00240 μL/g) se alcanzó con las condiciones óptimas de 23,5 FPU y 31,7 °C.  Se realizó una última corrida empleando las condiciones óptimas para una mayor carga de biomasa (20 g), alcanzando una concentración máxima de bioetanol de segunda generación de 0,11 mL/L.

Exceptions to compliance clauses in international economic law from an ecocentric approach and from the global south
Authors: Díaz-Botero Sergio , Villota David
Published: December 2022

This article intends to carry out an analysis that concerns the dynamics whit which International Economic Law, based on some provisions contained in its own regime, intends to exclude obligations that have been interpreted from other perspectives and that have been interpreted from other perspectives and that, over time, have gained prominence in international law discussion forums. The specific cases are limited to those settled in the WTO Dispute Settlement Body and the ICSID Appellate Body, all in relation to the interpretation generated in other systems from an alternative perspective and that may have a final impact for Europe, to finally seek a precedent-setting relationship such as the ICJ Whaling Convention (Australia v. Japan). It will seek to define from the CILT, the spirit whit which the exceptions contained in Article XX of the GATT emerged., which allows us to see an approach to the ecocentric approach that prevails today in a part of the world and that will soon be the dominant paradigm.

Authors: Leong Wei Cheng , Tang Jyh Jong
Published: December 2022

Introduction: Psoriasis affects approximately 2–3% of the population worldwide, although the overall prevalence in Asia is <0.5%. Scalp psoriasis is a common initial presentation of psoriasis, which affects almost 80% of patients with psoriasis.
Methods: This retrospective descriptive study investigated 1,671 patients with psoriasis with scalp involvement registered with the Malaysian Psoriasis Registry (MPR) from January 2007 to December 2018.
Results: A total of 21,859 patients with psoriasis were registered with the MPR during the study period; among them, scalp involvement was seen in 7.6% (n=1,671). Female sex preponderance (61%) was observed in the majority of Malay patients (58.5%), followed by the Chinese (16.9%), Indian (17.1%) and other ethnic patients (7.5%). A positive family history of psoriasis was identified in 22.7% (n=380). Approximately 34.8% (n=581) and 11% (n=172) of the patients had nail changes and psoriatic arthropathy, respectively. The mainstay treatment modality was topical treatment (93.6%), followed by systemic therapy (10%) and phototherapy (0.5%). The comorbidities found among the patients with scalp psoriasis included hypertension (27.9%), obesity (26%), dyslipidaemia (21%), diabetes mellitus (18.4%), ischaemic heart disease (5.4%) and cerebrovascular disease (1.3%). Approximately 23% reported a Dermatology Life Quality Index (DLQI) of >10, which indicated moderate-to-severe impairment.
Conclusion: The proportion of patients with psoriasis with scalp involvement in our study (7.6%) is much lower than previous reports. Scalp psoriasis markedly negatively impacts the DLQI.

Authors: Nathan Tanusha , Muthupalaniappen Leelavathi , Muhammad Noor Azimah
Published: December 2022

Introduction: Digital device helps children enhance academic, cognitive and psychomotor skills. However, prolonged use causes physical inactivity, poor interpersonal skills and communication problems. Information on digital device use among young children in Malaysia is currently limited. Hence, this study aimed to determine the prevalence of digital device utilisation among preschool children in Kota Setar District, Kedah.
Methods: A cross-sectional study at government preschools in Kota Setar District was conducted from February to April 2020. Selection of preschools and students was done using multistage simple randomisation. A self-administered questionnaire containing demographic and digital device use details was filled by parents.
Results: The prevalence of digital device use among preschool children was 95.9% and mostly used smartphones (94.2%). Most children (95%) did not own the device, and usage was under supervision (95.7%). The reason for supervision was to prevent exposure to inappropriate content (70.5%). The common reasons for allowing digital device use were for educational (37.4%) and entertainment purposes (36%) through videos (30.9%) and games (30.2%). Approximately 21.5% and 50.3% of the children spent more than 1 and 2 hours on digital devices during weekdays and weekends, respectively.
Conclusion: The prevalence of digital device use among the preschool children in Kota Setar District was very high. Most of them used digital devices for educational and entertainment purposes under parental supervision. However, some exceeded the recommended screen time on weekends. These findings could promote awareness of digital device use among young children and help design public health awareness programmes and future policies.

Authors: Rusito Rusito
Published: December 2022

The development of information system technology has penetrated the decision support system. Decision support systems can be applied in the selection of raw materials in manufacturing companies. The standard quantity of raw materials is the quantity of raw materials that should be used in the management of a particular product. Determining the standard of raw material quality starts from the application of product specifications, both regarding size, shape, color, characteristics, product processing and quality. Decision Support System (DSS) or Decision Support System (DSS) is a system which is able to provide alternatives in problem solving or can communicate for problems with semi-structured or unstructured conditions. This system is used to assist decision making in semi-structured and unstructured situations, where no one knows for sure how decisions should be made. Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) is a concept where the best chosen alternative not only has the shortest distance from the positive ideal solution, but also has the longest distance from the negative ideal solution. This concept is widely used in several MADM (Multi Attribute Decision Making) models to solve practical decision problems. Research development uses the R & D (Research and Development) method which is a research method used to produce certain products and test certain products. In this study, only 6 steps were used. The total score for validation is 28. Based on the above calculation, it can be concluded that the validation results from the experts show a value of 4.0 which is between 3.26 - 4.0 which is classified as a very valid category.

Many restaurant make their own order  and payment system   for  better service but they  forgot about  the speed of their services.Using research methods data collection, observation, and  interviewin Kedai Cangkir Gubug,  face to face service like greeting, take order, and serving order  all of it   is waiter’s  job.   All of that tasks need time at most that makes if the restaurant    have many customers, every single customer have to wait for  a longer time waiting for waiter that serving another customer. The payment method is quite troublesome for customer because they have to save order paper for payment in cashier later.The solution that writer’s made is to decrease the task of waiter so that services can be done equally with QRcode technology for ordering menu with the scanner is android smartphone. Payment only need name of customer or table number and customer can do it in cashier or they can request the bill at their table. Therefore waiter no need to take order one after another and customer can do payment easier.

Abstract. Iodine-initiated new particle formation (I-NPF) has long been recognized in
coastal hotspot regions. However, no prior work has studied the exact
chemical composition of organic compounds and their role in coastal
I-NPF. Here we present an important complementary study to the ongoing
laboratory and field research on iodine nucleation in the coastal atmosphere.
Oxidation and NPF experiments with vapor emissions from real-world coastal
macroalgae were simulated in a bag reactor. On the basis of comprehensive
mass spectrometry measurements, we reported for the first time a variety of
volatile precursors and their oxidation products in gas and particle phases
in such a highly complex system. Organic compounds overwhelmingly dominated
over iodine in the new particle growth initiated by iodine species. The
identity and transformation mechanisms of organic compounds were proposed in
this study to provide a more complete story of coastal NPF from low-tide
macroalgal emission.
A comparison of the climate and carbon cycle effects of carbon removal by Afforestation and an equivalent reduction in Fossil fuel emissions
Authors: Jayakrishnan Koramanghat Unnikrishnan , Bala Govindasamy
Published: December 2022

Abstract. Afforestation and reduction of fossil fuel emissions are two major components of climate mitigation policies. However, their effects on the earth’s climate are different because reduction of fossil fuel emissions directly alters the biogeochemical cycle of the climate system, while afforestation causes biophysical changes in addition to changes in the biogeochemical cycle. In this paper, we compare the climate and carbon cycle consequences of carbon removal by afforestation and an equivalent fossil fuel emission reduction using simulations from an intermediate complexity Earth system model. Our simulations show that the climate is cooler by 0.36 °C, 0.47 °C, and 0.42 °C in the long term (2471–2500) in the case of reduced fossil fuel emissions compared to the case with afforestation when the emissions follow the SSP2-4.5, SSP3-7.0, and SSP5-8.5 scenarios, respectively. Though afforestation results in a lower atmospheric CO2, the cooling from the reduced atmospheric CO2 is partly offset by the warming from surface albedo decrease associated with the regrowth of forests. Since this warming effect from surface albedo decrease is nearly absent in the reduced fossil fuel emission case, the climate is relatively cooler, even though the atmospheric CO2 levels are similar to the afforestation case. Thus, in terms of climate benefits, reducing fossil fuel emissions is relatively more beneficial than afforestation for the same amount of carbon removed from the atmosphere. Nevertheless, fossil fuel emission reduction and afforestation efforts should be pursued simultaneously as both lead to a decrease in global mean warming and reduced ocean acidification.

Abstract. A framework for quantifying precipitation distributions at regional scales is presented and applied to CMIP 5 and 6 models. We employ the IPCC AR6 climate reference regions over land and propose refinements to the oceanic regions based on the homogeneity of precipitation distribution characteristics. The homogeneous regions are identified as heavy, moderate, and light precipitating areas by K-means clustering of IMERG precipitation frequency and amount distributions. With the global domain partitioned into 62 regions, including 46 land and 16 ocean regions, we apply 10 established precipitation distribution metrics. The collection includes metrics focused on the maximum peak, lower 10th percentile, and upper 90th percentile in precipitation amount and frequency distributions, the similarity between observed and modeled frequency distributions, an unevenness measure based on cumulative amount, average total intensity on all days with precipitation, and number of precipitating days each year. We apply our framework to 25 CMIP5 and 41 CMIP6 models, and 6 observation-based products of daily precipitation. Our results indicate that many CMIP 5 and 6 models substantially overestimate the observed light precipitation amount and frequency as well as the number of precipitating days, especially over mid-latitude regions outside of some land regions in the Americas and Eurasia. Improvement from CMIP 5 to 6 is shown in some regions, especially in mid-latitude regions, but it is not evident globally, and over the tropics most metrics point toward over degradation.

Published: December 2022

Abstract. Observational data scarcity often limits the potential of rainfall-runoff modelling around the globe. In ungauged catchments, earth-observations or reanalysis products could be used to replace missing ground-based station data. However, performance of different datasets needs to be thoroughly tested, especially at finer temporal resolutions such as hourly time steps. This study evaluates the performance of ERA5-Land and COSMO-REA6 precipitation reanalysis products (PRPs) using 16 meso-scale catchments located in Slovenia, Europe. These two PRPs are firstly compared with a gridded precipitation dataset that was constructed based on ground observational data. Secondly, a comparison of the temperature data of these reanalysis products with station-based air temperature data is conducted. Thirdly, several data combinations are defined and used as input for the rainfall-runoff modelling using the GR4H model. A special focus is on the application of an additional snow module. Both tested PRPs underestimate, for at least 20 %, extreme rainfall events that are the driving force of natural hazards such as floods. In terms of air temperature both tested reanalysis products show similar deviations from the observational dataset that was catchment-specific. Additionally, air temperature deviations are smaller in winter compared to summer. In terms of rainfall-runoff modelling, the ERA5-Land yields slightly better performance than COSMO-REA6. If a re-calibration with PRP has been carried out, the performance is similar compared to the simulations where station-based data was used as input. Model recalibration proves to be essential in providing relatively sufficient rainfall-runoff modelling results. Hence, tested PRPs could be used as an alternative to the station-based based data in case that precipitation or air temperature data are lacking, but model calibration using discharge data would be needed to improve the performance.
A decade-plus of Antarctic sea ice thickness and volume estimates from CryoSat-2 using a physical model and waveform-fitting
Authors: Fons Steven , Kurtz Nathan , Bagnardi Marco
Published: December 2022

Abstract. We utilize a physical waveform model and a waveform-fitting method to estimate the snow depth and snow freeboard of Antarctic sea ice from CryoSat-2, and use these estimates to calculate the sea ice thickness and volume over an 11+ year time series. We compare our snow depth and thickness estimates to other altimetry- and ship-based observations, and find good agreement overall with some discrepancies in certain regions and seasons. The time series is used to calculate trends in the data, and we find small but statistically significant negative trends in the Ross Sea autumn (-0.3 cm yr-1), the Eastern Weddell winter (-0.8 cm yr-1), and the Western Weddell autumn and annual-average (-2.6 and -1.6 cm yr-1, respectively). Significant positive trends are found in the pan-Antarctic summer (0.4 cm yr-1) and Amundsen-Bellingshausen winter and annual-average (2.3 and 0.9 cm yr-1, respectively). Though pan-Antarctic trends in sea ice thickness and volume are small between 2010–2021, we find larger-magnitude trends regionally and since 2014. We place these thickness estimates in the context of a longer-term, snow-freeboard-derived, laser-radar sea ice thickness time series that began with ICESat and continues with ICESat-2. Reconciling and validating this longer-term, multi-sensor time series will be important in better understanding changes in the Antarctic sea ice cover.
Planting Seeds in Literary Narrative
Authors: Anderson Anne W.
Published: December 2022

On the surface, Yangsook Choi’s The Name Jar (2001) is a simple story of a very young immigrant girl who considers changing her name so her new classmates will like her.  Embedded within the story, however, are key onomastic concepts and questions: What are names? Who decides our names and how? Can we choose different names for different contexts and should we? If we change our names, does who we are change? I revisit scholarly conversations about onomastic theory and discuss narrative as a means of knowing. I draw on Nikolajeva’s (2003) work in narrativity, that is, the ways in which the narrative encourages or discourages deeper thought about the implications of the text. Using analytic reading strategies, I demonstrate how Choi’s uses of verbal and visual narrative devices give the story depth and create space for readers, including scholars, to parse out and ponder onomastic concepts and questions for themselves.
Psammead or It
Authors: Bardet Mary
Published: December 2022

Translating a name in children’s literature can be a delicate process, one that may be further complicated when the protagonist involved is a “Psammead”, a truly magical beast that is grammatically referred to with the pronoun “it”. This paper looks at the naming solutions utilized in three different French translations of E. Nesbit’s work. It examines the difficulties of translating names from English, a language with natural gender, into French, a language with grammatical gender. Using close text analysis and reader-response surveys, this article investigates readers’ cognitive responses, and determines whether readers of the English and French texts construct the same mental representation of the Psammead. As will be shown in this study, naming decisions made for translations can modify more than just the grammatical gender seen on the page. When an “it” becomes an “elle” or “she”, a mythical creature can become completely re-gendered.
