Simulated range of mid-Holocene precipitation changes to extended lakes and wetlands over North Africa
Authors: Specht Nora Farina , Claussen Martin , Kleinen Thomas 
Published: October 2021

Abstract. Enhanced summer insolation over North Africa induced a monsoon precipitation increase during the mid-Holocene, about 6000 years ago, and led to a widespread expansion of lakes and wetlands in the present-day Sahara. This expansion of lakes and wetlands is documented in paleoenvironmental sediment records, but the spatially sparse and often discontinuous sediment records provide only a fragmentary picture. Former simulation studies prescribed either a small lake and wetland extent from reconstructions or focused on documented mega-lakes only to investigate their effect on the mid-Holocene climate. In contrast to these studies, we investigate the possible range of mid-Holocene precipitation changes in response to a small lake extent and a potential maximum lake and wetland extent. Results show that the maximum lake and wetland extent shift the North African rain belt about 3 ° farther northward than the small lake extent. Vegetated wetlands cause a larger precipitation increase than the equally-large lakes due to their high surface roughness. A moisture budget analysis reveals that both, lakes and wetlands, cause an enhanced inland moisture transport and local moisture recycling to their southern side. In contrast, increased moisture advection by the Harmattan winds causes a drying response to the north of the lakes and wetlands. These results indicate that the latitudinal position of the lakes and wetlands influences the northward extension of the African summer monsoon. In the sensitivity experiments, the northern position of West Saharan lakes and wetlands substantially contributes to the strong monsoon northward shift seen in the maximum lake and wetland simulations.

Abstract. Knowledge of past ice sheet configurations is useful for informing projections of future ice sheet dynamics and for calibrating ice sheet models. The topology of grounding line retreat in the Ross Sea sector of Antarctica has been much debated, but it has generally been assumed that the modern ice sheet is as small as it has been for more than 100 000 years (Conway et al., 1999; Lee et al., 2017; Lowry et al., 2019; McKay et al., 2016; Scherer et al., 1998). Recent findings suggest that the West Antarctic Ice Sheet (WAIS) grounding line retreated beyond its current location earlier in the Holocene and subsequently readvanced to reach its modern position (Bradley et al., 2015; Kingslake et al., 2018). Here, we further constrain the post-LGM (Last Glacial Maximum) grounding line retreat and readvance in the Ross Sea sector using a two-phase model of radiocarbon input and decay in subglacial sediments from six sub-ice sampling locations. In addition, we reinterpret high basal temperature gradients, measured previously at three sites in this region (Engelhardt, 2004), which we explain as resulting from recent ice shelf re-grounding accompanying grounding line readvance. At
one location – Whillans Subglacial Lake (SLW) – for which a sediment
porewater chemistry profile is known, we estimate the grounding line
readvance by simulating ionic diffusion. Collectively, our analyses indicate that the grounding line retreated over SLW 4300-2500+1500 years ago, and over sites on Whillans Ice Stream (WIS), Kamb Ice Stream (KIS), and Bindschadler Ice Stream (BIS) 4700-2300+1500, 1800-700+2700, and 1700-600+2800 years ago, respectively. The grounding line only recently readvanced back over those sites 1100-100+200, 1500-200+500, 1000-300+200, and 800±100 years ago for SLW, WIS, KIS, and BIS, respectively. The timing of grounding line retreat coincided with a warm period in the mid-Holocene to late Holocene. Conversely, grounding line readvance is coincident with cooling climate in the last 1000–2000 years. Our estimates for the timing of grounding line retreat and readvance are also consistent with relatively low carbon-to-nitrogen ratios measured in our subglacial sediment samples (suggesting a marine source of organic matter) and with the lack of grounding zone wedges in front of modern grounding lines. Based on these results, we propose that the Siple Coast grounding line motions in the mid-Holocene to late Holocene were primarily driven by relatively modest changes in regional climate, rather than by ice sheet dynamics and glacioisostatic rebound, as hypothesized previously (Kingslake et al., 2018).
Adolescent Psychological Well-Being: The Case of Filipino Catholic High School Students with Absentee Parents
Authors: Sablaon Cecilia M. , Madrigal Dennis V. 
Published: October 2021

Psychological well-being (PWB) refers to a person's quality of looking at things and situations. Despite one's limitations, he/she can overcome challenges and live a satisfying, productive, and happy life. This descriptive-correlational research design assessed the level of psychological well-being of Catholic high school students with absentee parents of a private school in Antique, Philippines, during the school year 2019-2020. Selected using stratified random sampling, there were 85 respondents who participated in the study. The data were collected using Ryff's item Psychological Well-Being Scale test. Mean, standard deviations, and Spearman rank correlation were used to analyze the data. The findings of the study showed that the level of psychological well-being of Catholic high school students with absentee parents of a private school in Antique was high. Categories on personal growth, positive relations, and purpose in life were also high, while autonomy, environmental mastery, and self-acceptance were moderate. In addition, a significant relationship was found between family monthly income, academic level, and involvement in Church ministry and PWB. Meanwhile, sex and attendance on Sunday masses had no significant relationship with PWB. Thus, Catholic students demonstrated a positive view of life and cope with challenges despite the absence of their parents.

Для обеспечения надлежащего качества и безопасности алкогольной продукции перед поставкой ее потребителям выполняется определение количественного содержания летучих компонентов. Данный контроль выполняют на газовых хроматографах. Количественный расчет значений концентраций выполняют по методу внешнего стандарта и по методу внутреннего стандарта. Метод внешнего стандарта используется в межгосударственных стандартах: ГОСТ 30536-2013, ГОСТ 31684-2012, ГОСТ 33833-2016, ГОСТ 33834-2016, ГОСТ 33408-2015, ГОСТ 31684-2012 и в государственных стандартах ГОСТ Р 52363-2005 и СТБ ГОСТ Р 51698-2001. С целью достижения высокой достоверности получаемых данных при контроле качества и безопасности алкогольной продукции, уменьшения материальных, финансовых и трудовых затрат предложен инновационный метод, заключающийся в использовании этилового спирта, содержащегося в испытуемом образце, в качестве внутреннего стандарта. Эффективность метода продемонстрирована на примере сравнительного анализа результатов определения количественного содержания летучих компонентов в широком спектре алкогольной продукции, выполненного по используемому в настоящее время методу внешнего стандарта и по предложенному методу. Показано, что для валидации метода и последующего его внедрения в практику испытательных лабораторий не требуется каких-либо дополнительных материальных, финансовых или трудовых затрат.
To ensure the proper quality and safety of alcoholic beverages, the quantitative content of volatile compounds is determined before delivery to consumers. This control is performed on gas chromatographs. The quantitative calculation of the concentration values is carried by external and internal standard methods. The external standard method is used in standards: GOST 30536-2013, GOST 31684-2012, GOST 33833-2016, GOST 33834-2016, GOST 33408-2015, GOST 31684-2012 and in state standards GOST R 52363-2005 and STB GOST R 51698-2001. In order to achieve high reliability of the data obtained when controlling the quality and safety of alcoholic beverages, and to reduce material, financial and labor costs, an innovative method is proposed. This method is based on using ethyl alcohol, contained in the test sample, as an internal standard. The effectiveness of the method is demonstrated by the example of a comparative analysis of the results of determining the quantitative content of volatile compounds in a wide range of alcoholic beverages, performed according to the currently used external standard method and according to the proposed method. It is shown that for validation the method and its subsequent implementation into the practice of testing laboratories does not require any additional material, financial or labor costs.

Maus y la ética de la representación después del Holocausto Narrativas post-traumáticas, elaboración y post-memoria. / Maus and the Ethics of Representation After the Holocaust Post-traumatic narratives, elaboration and post-memory.
Authors: Vetö Silvana 
Published: October 2021

En este trabajo se examinarán algunos de los problemas éticos que el Holocausto ha planteado a los medios de representación de la historia, para luego ligar las distintas narrativas que resultan de dichas representaciones, con las posibilidades de duelo y elaboración. Se abordarán primero los planteamientos de Theodor Adorno respecto de las posibilidades del arte frente al sufrimiento. Luego se expondrán algunos aspectos del debate surgido al final de la década del 70 a propósito de la representación del Holocausto en medios de comunicación de masa y en la “alta” cultura. Se mostrará como persiste en ese debate una perspectiva dicotómica respecto del trauma, de la cual surgen dos tipos de narrativas post-traumáticas supuestamente irreconciliables, que no permiten una adecuada elaboración y un duelo satisfactorio respecto de las pérdidas implicadas en el acontecimiento traumático. Finalmente, analizaremos en detalle la novela gráfica Maus. Relato de un superviviente, cuya narrativa experimental permite cuestionar y deconstruir la dicotomía redención/aporía de manera novedosa, planteando nuevos problemas vinculados a la memoria del Holocausto y a la posibilidades de duelo.
In this work, we will focus on some of the ethical problems that the Holocaust has posed to the representation of historical limit-events. We will then link the different narratives emerging from these representations to the possibilities of mourning and elaboration. First, we will examine the German philosopher Theodor Adorno’s propositions concerning the possibilities of art in the face of suffering. Then, we will present some aspects of the debate that arose in the late 70s regarding the representation of the Holocaust in mass media and in ‘high’ culture. It will be shown how in this debate there persists a dichotomist perspective of trauma, which creates two supposedly irreconcilable types of post-traumatic narratives that do not permit an appropriate elaboration and mourning of losses caused by the traumatic event. Finally, we will analyze the graphic novel Maus. A Survivor’s Tale, whose experimental and open narrative allows an original questioning and deconstruction of the redemption/aporia dichotomy, putting forward new problems related to the memory of the Holocaust and the possibilities of mourning.
