Trapped in between Duties and Desires: The Mill on the Floss
Authors: Gökçek Aycan
Published: June 2023

This chapter is an examination of restrictions imposed upon Victorian women as well as limitations and inequalities that paralyze and imprison them on George Eliot’s popular novel The Mill on The Floss with an emphasis on the protagonist Maggie Tulliver. Initially, background information on the author is presented, then the novel is handled from the perspective of woman question in the Victorian Era juxtaposing the circumstances provided to the male and female child in the Victorian era in which cleverness is regarded as a trouble rather than a virtue. The qualities of New Woman are also scrutinized with the protagonist Maggie. Pointing out the dilemma the protagonist experiences in between her duties and desires in a patriarchal society that limits women from educational, intellectual and social aspects allowing them no pleasure of life, this chapter reveals that Victorian Women were regarded as the angels in the house who need to be protected by men. To conclude, this chapter handles The Mill on The Floss as a critique of Victorian Society which suffocates women leaving them no space for pleasure, intellectuality and individuality and emphasizes that such a society is actually no good for both males and females.
Principles of Soil Erosion Risk Modeling
Authors: Aghaei Dargiri Soheila , Samsampour Davood
Published: June 2023

It is anticipated that modern agriculture practice patterns will accelerate soil erosion in a negative way. Evaluating the long-term impact of various management strategies on a large farm is a gauge of the sustainable practices of soil nutrients. To find areas at risk, there are generally three different methods used: qualitative research, statistical approach, and model approach. Each of these approaches has distinctive features and applications. The use of geographic databases created using GIS technology has improved all techniques and strategies created recently. The sustainability of agricultural ecosystems worldwide is severely threatened by low or nonexistent attention given to environmental impact assessments, which also seriously threaten soil systems. Both conventional field-based methodologies and soil erosion modeling can be employed to quantify soil erosion. Agricultural automation has increased along with the accessibility of finer scale global level data, strengthening agri-environmental related modeling approaches. Due to the laborious, moment, limited flexibility, and noncomparability of field-based methods, soil erosion modeling has many advantages over these assessments. The examined models will be examined this season in the direction of wind erosion. The model is useful for forecasting and highlighting the areas most impacted by erosion while also saving time and resources.
Importance of Supplementation during In Vitro Production of Livestock Animals
Authors: Nemcova Lucie , Rosenbaum Bartkova Alexandra , Kinterova Veronika , Toralova Tereza
Published: June 2023

Increasing infertility is one of the most serious health problems of today. Over the past few years, we have had the opportunity to follow the progress of technologies focused on the production of embryos in vitro (i.e., in vitro fertilization and intracytoplasmic sperm injection, genetic engineering, or somatic cell nuclear transfer. Oocyte maturation is one of the most important processes in the production of embryos in vitro. Despite recent progress in this field, the developmental competence of in vitro generated oocytes is significantly lower than in vivo. In the last few years, a large number of studies dealing with the improvement of in vitro conditions for embryo culture have been published. These results have huge application potential in the reproduction of farm animals as well as in human medicine. Incorporating various elements, such as serum, hormones, growth factors, and antioxidants, can affect not only oocyte maturation or embryo culture but also an oocyte/embryo quality. The aim of this chapter is to summarize the most important types of supplementations of maturation and culture media and their impact on the improvement of in vitro oocyte and embryo production of farm animals.
Graphic novels as counter-stories: Jerry Craft’s New Kid as a way to teach critical racial awareness
Authors: Lentz Christina
Published: June 2023

This chapter examines Jerry Craft’s 2019 published graphic novel New Kid by applying Critical Race Theory (CRT). New Kid is based on autobiographic experiences of being African American at an American, mainly white, (elite) school, and can therefore be read as a “counter-story”. It is written out of the perspective of 12- year-old black boy, Jordan Banks, who is a “New Kid” at the private Riverdale Academy. The book has caused a nationwide debate in the US, being accused of preaching Critical Race Theory (CRT). Craft meanwhile claims that he did not write it with any political intentions. The article takes this debate as point of departure to first explain the main tenets of CRT and to explore in what way New Kid can be read as a counter-story in the sense of CRT. The analysis shows that New Kid reflects structural racism towards African Americans (e.g., microaggressions, othering and deficit orientation) in an educational context and reveals the negative consequences of racism for students’ self-perception.

In the second part, the article investigates possibilities to teach New Kid in a European setting, taking the new Norwegian curriculum (Kunnskapsløftet) as an example. New Kid is identified as an appropriate medium to discuss race in Norwegian schools. This is particularly because of the sophisticated way New Kid approaches racism. At the same time New Kid itself can be examined for racism towards other marginalized groups, namely Asian Americans.

The high intensity of flooding in Indonesia makes people have to be aware of flood disasters. An important factor in flood disaster management is community preparedness which requires knowledge about flood disaster risks. The purpose of this study was to determine the relationship between the level of knowledge with flood disaster preparedness in the community. This research design is correlation analytic with cross sectional approach. The population of this study were all responsible family heads aged 20-50 years, totalling 143 families. In this study using simple random sampling (n = 38 people). The instrument used was a questionnaire. The results showed that most of the respondents had sufficient knowledge 25 people (65.8%), most of the respondents were alert to flood disasters 25 people (65.8%). The results of the Spearman Rho test analysis obtained a pvalue of 0.000 less than α (0.05) and a coefficient correlation value of 0.678 so that H1 is accepted, which means that there is a strong relationship between the level of knowledge and preparedness for flood disasters in the community. Knowledge will affect the community's concern to be ready and alert in anticipating disasters, especially for those who live in areas vulnerable to flooding.

Authors: Tri Peni  , Heri Triwibowo  , Sindy Aprilia
Published: June 2023

Adolescence is a period of transition from childhood to adulthood. Puberty for girls is marked by the onset of menstruation. The lack of knowledge among young women in carrying out personal hygiene can be at risk for the growth of microbes that cause vaginal odor and vaginal discharge to occur. This causes various diseases of the reproductive organs. One way to increase knowledge is by providing health education. This study aims to determine the effect of audio-visual media health education on increasing female adolescent knowledge about personal hygiene during menstruation. The research design used a one-group pretest-post-test design. The population in this study were all 7th-grade female students of SMP 3 Silo, totaling 59 students. The sampling technique of this research is accidental sampling. The research sample is 54 respondents. The research instrument used a questionnaire. Data analysis using the Wilcoxon Signed Rank Test. The results showed that almost all respondents had sufficient knowledge before being given health education, namely 45 people (83.3%), and almost all respondents had good knowledge after being given health education, namely 43 people (79.6%). The results of the Wilcoxon test showed that p-value = 0.000 so there was an effect of audio-visual media health education on increasing knowledge about personal hygiene during menstruation. Audiovisual aids are capable of displaying moving pictures, writing, and animation accompanied by sound so that it is not boring and the information received is clearer and more quickly understood.
Tumor Heterogeneity Confounds Lymphocyte Metrics in Diagnostic Lung Cancer Biopsies
Authors: Elfving Hedvig , Thurfjell Viktoria , Mattsson Johanna Sofia Margareta , Backman Max , Strell Carina , Micke Patrick
Published: June 2023

Context.—

The immune microenvironment is involved in fundamental aspects of tumorigenesis, and immune scores are now being developed for clinical diagnostics.

Objective.—

To evaluate how well small diagnostic biopsies and tissue microarrays (TMAs) reflect immune cell infiltration compared to the whole tumor slide, in tissue from patients with non–small cell lung cancer.

Design.—

A TMA was constructed comprising tissue from surgical resection specimens of 58 patients with non–small cell lung cancer, with available preoperative biopsy material. Whole sections, biopsies, and TMA were stained for the pan-T lymphocyte marker CD3 to determine densities of tumor-infiltrating lymphocytes. Immune cell infiltration was assessed semiquantitatively as well as objectively with a microscopic grid count. For 19 of the cases, RNA sequencing data were available.

Results.—

The semiquantitative comparison of immune cell infiltration between the whole section and the biopsy displayed fair agreement (intraclass correlation coefficient [ICC], 0.29; P = .01; CI, 0.03–0.51). In contrast, the TMA showed substantial agreement compared with the whole slide (ICC, 0.64; P < .001; CI, 0.39–0.79). The grid-based method did not enhance the agreement between the different tissue materials. The comparison of CD3 RNA sequencing data with CD3 cell annotations confirmed the poor representativity of biopsies as well as the stronger correlation for the TMA cores.

Conclusions.—

Although overall lymphocyte infiltration is relatively well represented on TMAs, the representativity in diagnostic lung cancer biopsies is poor. This finding challenges the concept of using biopsies to establish immune scores as prognostic or predictive biomarkers for diagnostic applications.
BREEDING ECOLOGY, NESTING HABITAT AND THREATS TO A BLACK-AND-CHESTNUT EAGLE SPIZAETUS ISIDORI POPULATION IN THE MONTANE FORESTS OF CENTRAL PERU
Authors: Rivas Fuenzalida Tomás Antonio , Orizano Daniel , Cuadros Sandra , Quispe-Flores Yisela , Burgos-Andrade Katherine
Published: June 2023

The Black-and-chestnut Eagle Spizaetus isidori is an endangered and little-known top predator of South American montane forests. To better understand the breeding ecology and threats of this eagle, we studied several pairs between 2017 and 2022 in the central Andes of Peru. We recorded 62 adults, one immature, and 36 juveniles in 36 territories. These territories were in mountainous areas (altitudinal range 690–3,810 m a.s.l.), widely covered by montane forests (43.8–99.7% cover), and secondarily by open land (0.3–56.2% cover), far from urban settlements (1.3–27.1 km). Nesting sites (N = 15) were at medium altitudes (1,330–2,330 m a.s.l.) in steep hillsides or ravines (15–55°), having no preferential cardinal orientation, and relatively close to permanent water courses (20–800 m), open areas (30–930 m) and sites with human activity (120–2,200 m). Nests (N = 15) were placed at the top of tall (28–40 m) and thick-stemmed (DBH range 0.53–1.52 m) emergent trees of nine genera, with Ficus and Juglans being the most used. Incubation and brood-rearing occurred during the dry season (Mar–Nov). The wooded slopes where the eagles nested are being replaced by crops and livestock pastures, causing an estimated loss of 218.2 km2 of forest cover in our study area (5,056 km2) during the last 20 years. We detected human persecution in 55.5% of the territories, resulting in 26 juveniles, four adults, two immatures, and nine unaged eagles killed. Preventing the local extinctions of these eagles will require long-term population monitoring, improving knowledge of its ecology, mitigation of human-eagle conflict, development of education programs, and strengthening of land use inspection.

Learning outcomes assessment plays a significant role in teaching and learning, not only does it motivate learners but also provide information about how newly transmitted knowledge has been absorbed by learners. It is obviously true that both teachers and students require to adjust the content, teaching and learning methods to achieve the set goals. Using the Google Forms tool, teachers can easily assess students understanding in English Grammar classes at HIU. This study aims to explore the opinions of HIU students about the Google Form tool in reviewing and testing English Grammar knowledge. The research team used qualitative and quantitative methods to collect data from 94 first-year students of the English Language Department of Hong Bang International University. Specific methods for data collection are observations, interviews, and online surveys. Initial results show that the majority of students have positive comments about this assessment tool such as creating excitement, motivation, ease of use, receiving instant scores and feedback;in addition , students can self-test many times, which helps them memorize the content quickly. However, there are also a few students who believe that this tool is dependent on technology, limited to some types of exercises, and does not comprehensively foster students' creative and application skills.
Factors affecting language acquisition in the digital switch

Published: June 2023

These aspects motivational and affective effects of language learning have largely been neglected by researchers despite having a monumental influence on the acquisition of language. For this paper, I would like to address the roles of motivation and affective effects on second language acquisition by addressing the following questions: 1) What are the roles of motivation and affective effects in language acquisition? 2) What are the triggers of these effects and how they affect students learning process? 3) What can teachers do to raise or alleviate these effects for the betterment of language learning? For the first question, this paper will explore the role of motivation in language acquisition by using citations from Celce-Murcia, Brinton, & Snow (2014), Meniado (2019), Dörnyei, Z. (1990), etc. To answer the second question, the paper will discuss the prompts and input for various affective effects and their influence on students through Garrett & Young (2009). The effects on language would also be discussed using study by Pavlenko & Dewaele (2004), Dewaele (2005), Tran, Thu H. (2013) etc. For the final question, the paper will provide suggestions and approaches to address the motivational and affective elements of language acquisition from Celce-Murcia, Brinton, & Snow (2014) as well as tasks and strategies to raise motivation from both teachers and students Dörnyei (2003).
Test-retest reliability of the Nordic Musculoskeletal questionnaire (NMQ) in Vietnamese physical therapists
Authors: Le Thi Thach Thao
Published: June 2023

Background: The Nordic Musculoskeletal Questionnaire (NMQ) is one of the screening tools to assess pain or discomfort of musculoskeletal disorders. It is widely used in various occupational populations. Many previous studies investigated the reliability of the NMQ, but there are no evidences in Vietnam. Objective: This study evaluated the test-retest reliability of the question about trouble with the locomotive organs in the NMQ in Vietnamese physical therapists (VPTs). Materials and method: It was a cross-sectional study in 10 VPTs by a convenient sampling technique. An online questionnaire was distributed to all participants twice times with a 7-day interval. They reported their musculoskeletal disorders during the last 12 months and the last 7 days and been prevented from doing normal work because of their troubles. The test-retest reliability of dichotomous data produced by the NMQ was accessed by using the kappa coefficient (k) and the level of significance was set at a p-value of less than 0.05. Results: Among 27 binary choice items, there were 5 items where k could not be computed as response were 100% negative on both testing occasions. Eight items showed not significant correlation poor to moderate agreement (k ≤ 0.40, p-value > 0.05). Fourteen items showed substantial to excellent test-retest reliability (k = 0.74-1.00, p-value < 0.05). Conclusion: The results suggest that the NMQ can be used with acceptable reliability for evaluating the musculoskeletal disorders and labour risks among VPTs.

In this paper (Rubin, 2017), I consider Gelman and Loken’s (2013, 2014) garden of forking paths problem. Forking paths occur when researchers decide which analyses to perform based on information from their sample. For example, a researcher may decide whether or not to drop an item from a scale based on how it affects the scale’s Cronbach alpha coefficient within the current sample. This sample-contingent decision rule causes a forking path in the analysis protocol because, during the course...

Published: June 2023

The aim of this study was to determine the impact of additions of tungsten carbide and silicon carbide microparticles to the lubricant used in the burnishing process on the tribological properties of friction pairs. The cylinders made of AISI 1045 steel constituted a workpiece. Burnishing was made with a lubricant the SN150 base oil with addition of tungsten carbide and silicon carbide microparticles. The tested materials were burnished with forces of 1000 N and 1500 N. Before and after the burnishing process, the surface roughness and hardness of the tested materials were measured. The study also presents the results of tribological properties of friction pairs with the tested structural materials. It was found that the addition of tungsten carbide microparticles to the base oil in the burnishing process can result in improved surface quality and reduced surface roughness. The results also confirmed the effect of addition of tungsten carbide and silicon carbide to the lubricant used in the burnishing process on tribological properties.

Published: June 2023

The sliding failures commonly occur in interbedded formations along the weakness plane of the bedding plane a sedimentary rock or the joint interface. Therefore, studying the shear strength characteristics at the bedding plane or interface is crucial for evaluating the expected failure plane. In this study, the shear strength characteristics of planar jointed Kenny Hill shale, sandstone, and shale-sandstone specimens were investigated using the direct shear box method. The results reveal that the friction angle values for the planar sandstone, shale-sandstone, and shale are 31.28°, 21.1°, and 19.34°, respectively. These findings, combined with the shear stress-strain behavior, suggest that the interface (shale-sandstone) is primarily influenced by the shale characteristics rather than the sandstone characteristics. Hence, it is important to consider failure along the interface when analyzing critical conditions, particularly in slope failure scenarios.

A reappraisal of the distribution of the Yellow-headed Manakin (Chloropipo flavicapilla) in Colombia and Ecuador
Authors: Palacio Rubén Darío
Published: June 2023

The Yellow-headed Manakin (Chloropipo flavicapilla) is a rare and threatened species that is thought to occur between the Andes of Colombia and  northeastern Ecuador. However, only three records support the presence of C. flavicapilla in Ecuador: a 19th-century specimen from Hacienda Mapoto, Tungurahua province, and two undocumented field observations from the early 1990s — one from Cordillera de Guacamayos and one from Volcán  Sumaco. I investigated these records and found that the Mapoto specimen is a Green Manakin (Cryptopipo holochlora) deposited in the Museum and Institute of Zoology, Polish Academy of Sciences (MIZ 22050). The correct specimen identity was reported by Hellmayr (1929), but his notes were overlooked. The two undocumented sightings occurred in well-surveyed areas populated with eBird hotspots that are frequently visited by birders.  Furthermore, there are no publicly available records of C. flavicapilla for these locations or anywhere else in Ecuador. Lastly, I analyzed the species distributional limits in southern Colombia. Two biogeographical barriers limit its distribution to northern Ecuador: (1) The Patía Valley in the western Andes and (2) the Colombian Massif in the central and eastern Andes. In conclusion, there is no tangible evidence that C. flavicapilla has been recorded in Ecuador,  and based on its current distribution, it should be considered endemic to Colombia.

Published: June 2023

Gelatin is commonly used as a gelling and thickening agent in confectionery products and is considered a critical material in terms of its halal status. Real-time Polymerase Chain Reaction (real-time PCR) is frequently employed as an analytical tool to detect traces of pork in food items. Although the real-time PCR method using the Tanabe primer and Internal Positive Control (IPC) has been validated effectively, its sensitivity or Limit of Detection (LOD) for confectionery products has yet to be determined. This study aims to determine the sensitivity of real-time PCR with Tanabe primers and IPC towards the confectionery products (gummy candy, marshmallow, and lozenges). Confirmation of this method on commercial marshmallow products known to contain porcine gelatin was also carried out. In this study, the LOD (% w/w) of porcine gelatin in bovine gelatin was initially determined. The findings revealed that the LOD (% w/w) was 0.01% with a cycle threshold (Ct) value of 39.20±1.72. The next step involved determining the LOD (% w/w) of porcine gelatin in various confectionery products such as lozenges, gummy candy, and marshmallows. The LOD (% w/w) for lozenges and gummy candy was found to be 0.1% with Ct values of 40.93±0.15 and 38.72±0.18, respectively. Marshmallows exhibited an LOD of 0.01% with a Ct value of 41.14±2.96.

Consumption of honey has increased in recent years. This included trigona honey as a new market that is developing. This research was conducted to (1) identify the consumption patterns for Indonesian honey, and (2) identify the sensory attributes of honey considered ideal by consumers which influence consumer acceptance and satisfaction. There were 2 stages of activity in this study, including a consumption online survey by 225 respondents and a sensory testing of honey samples using the CATA (check-all-that-apply) method involving 64 untrained panelists. Data analysis was carried out using SPSS and XLSTAT 2022 software. There were 4 honey samples used in this study: 2 Apis bee honey samples and 2 trigona honey samples. The study showed that the consumption pattern of Indonesian honey consumers is influenced by the consumers’ age and income. Health benefits, brand awareness, and taste of honey were the important factors in consumer behavior. Apis bee honeys were perceived as the ideal honey by consumers as they were very familiar with the taste. The sweet aroma, sweet aftertaste, caramel flavor, and viscous attributes of Apis bee honey were the attributes that the consumers like. The floral flavor and fruity aroma found in trigona honey were appealing. However, the strong sour aroma, taste, and aftertaste found in trigona honeys decrease the Indonesian consumers liking.

À quoi sert une frontière ? (à propos de 'Le Cabinet des Merveilles' de Mario Pasa, 'Celui qui est digne d’être aimé' d’Abdellah Taïa et 'Zinc' de David Van Reybrouck)
Authors: Marinho Maria de Fátima
Published: June 2023

La formation d’une nation convoque théoriquement la sensation d’appartenance à un groupe et l’idée que les différences entre les individus sont bien moins importantes que les affinités qui les rassemblent. Si l’on considère que la notion d’identité doit être fondamentale pour la création d’une nation, alors il faut absolument que les frontières et les liens d’appartenance ne soient pas séparés. Sachant que cette affirmation est loin d’être vraie, on essaiera de démontrer comment les romanciers réussissent à théoriser et à actualiser ces notions. Le Cabinet des Merveilles de Mario Pasa, Celui qui est digne d’être aimé d’Abdellah Taïa et Zinc de David Van Reybrouck seront des exemples à retenir.
De l’Orient à l’Occident : migration et reterritorialisation identitaire chez Mahmud Nasimi
Authors: Zango Achille Carlos
Published: June 2023

Cet article questionne la portée de la migration dans la reterritorialisation identitaire de Mahmud Nasimi à travers son récit Un Afghan à Paris (2021). En effet, à son arrivée dans la mythique ville de Paris, après avoir perçu dans la langue française un moyen de textualisation du parcours tumultueux subi depuis le départ de son pays d’origine, l’Afghanistan, jusqu’à celui d’accueil, la France, l’auteur a également trouvé dans cette langue un moyen de construction de son identité plurielle. Tout part de sa découverte de l’art européen et surtout de la littérature française qui deviendra pour lui la source du déclic de l’appropriation de l’ailleurs. Entre la terre d’origine secouée par des crises multiples, l’étranger s’impose finalement à l’auteur comme terre de reterritorialisation identitaire. En nous servant des approches autofictionnelle et intermédiale, ces lignes démontrent que l’écriture et la thématique d’Un Afghan à Paris sont l’expression de la rencontre entre deux aires culturelles : l’Occident et l’Orient.
Au croisement de la littérature, du reportage et de l’enquête : le Nouveau Journalisme français contemporain
Authors: Hansen-Løve Sven
Published: June 2023

En France, comme dans le reste du monde, le Nouveau Journalisme rencontre un succès grandissant. Devenu désormais incontournable dans le paysage culturel, il se situe à l’intersection du journalisme et de la littérature dans sa conception classique. En cela, on peut estimer qu’il est bien en phase avec l’époque, où les formes hybrides – le croisement des genres dans leurs pluralités – après avoir été longtemps désapprouvées, se voient enfin consacrées. Le Nouveau Journalisme français, que l’on appelle aussi journalisme littéraire, se veut toujours plus en prise avec l’humain, à l’écoute des différentes voix et récits, considérés dans leur singularité, tout en apportant une attention constante aux évolutions de la société. La démarche de ces « reporters du réel » tel qu’ils aiment à se définir eux-mêmes, s’appuie en grande partie sur une exploration minutieuse du quotidien. La méthode repose également sur une immersion absolue dans leur sujet, soit par le biais de très longues enquêtes sur le terrain, soit par l’analyse approfondie de faits divers emblématiques. Ces enquêtes d’un nouveau genre, intégrant plusieurs disciplines (littérature, sociologie et journalisme), agissent à la manière d’un puissant révélateur, exposant au grand jour les failles et les injustices de nos systèmes.
Fuel Consumption Evaluation of Connected Automated Vehicles Under Rear-End Collisions
Authors: Liu Qingchao , Ouyang Wenjie , Zhao Jingya , Cai Yingfeng , Chen Long
Published: June 2023

Connected automated vehicles (CAV) can increase traffic efficiency, which is considered a critical factor in saving energy and reducing emissions in traffic congestion. In this paper, systematic traffic simulations are conducted for three car-following modes, including intelligent driver model (IDM), adaptive cruise control (ACC), and cooperative ACC (CACC), in congestions caused by rear-end collisions. From the perspectives of lane density, vehicle trajectory and vehicle speed, the fuel consumption of vehicles under the three car-following modes are compared and analysed, respectively. Based on the vehicle driving and accident environment parameters, an XGBoost algorithm-based fuel consumption prediction framework is proposed for traffic congestions caused by rear-end collisions. The results show that compared with IDM and ACC modes, the vehicles in CACC car-following mode have the ideal performance in terms of total fuel consumption; besides, the traffic flow in CACC mode is more stable, and the speed fluctuation is relatively tiny in different accident impact regions, which meets the driving desires of drivers.
Numerical simulation of seawater intrusion in the lower Seybouse aquifer system, Algeria
Authors: Hani Samir , Toumi Fayçal , Bougherira Nabil , Shahrour Isam , Hani Azzedine
Published: June 2023

Seawater intrusion represents a high risk for the water supply, the agriculture and industry activities in the lower Seybouse region of North-Eastern Algeria. In order to analyze this risk, a three-dimensional model was developed using the MODFLOW and MT3DMS codes to predict seawater intrusion in the coastal aquifer. The application of this model indicates that the groundwater withdrawals result in a continuous decrease of the water level and in an increase of chloride concentration. Moreover, the salt front could progress by 300 to 2500 m in the land. These results show the necessity of adequate measures for the protection of the aquifer. Numerical predictions for 2045, considering an increase of groundwater withdrawals by 20%, show a fairly significant decrease in water levels, up to -6 m with respect to the mean sea level, and an increase of Cl- concentrations up to about 10 km inland.

As comissões da verdade e os arquivos da ditadura militar brasileira
Authors: Tenaglia Mônica
Published: June 2023

Esta obra explora o contexto histórico-legal das comissões da verdade no Brasil e no mundo e reconstrói as estratégias e ações das comissões brasileiras para o acesso aos arquivos da ditadura militar (1964-1985). A partir da análise da emergência do reconhecimento dos arquivos para as investigações sobre violações dos direitos humanos e a efetivação do direito à informação, à verdade e à memória, o livro discute o fenômeno da criação de comissões da verdade em todo o território nacional brasileiro e as relações das comissões com os arquivos. Nesse sentido, evidenciam-se a insuficiência das políticas de gestão documental e um quadro de negação, ocultamento e destruição dos arquivos do período da ditadura militar. Todavia, identifica-se que, apesar dos problemas e limitações, as comissões da verdade conseguiram criar estratégias e implementar ações para superar essas dificuldades, dentre elas, parcerias com as universidades, especialmente com os cursos de Arquivologia. Como lacuna na atuação das comissões da verdade no Brasil, o livro constata que foram poucas as ações educativas realizadas fora dos círculos acadêmicos e voltadas a uma parcela mais ampla da população brasileira.
Our Ancient Lakes
Authors: McKinnon Jeffrey
Published: June 2023

The unexpected diversity, beauty, and strangeness of life in ancient lakes—some millions of years old—and the remarkable insights the lakes are yielding about the causes of biodiversity.

Most lakes are less than 10,000 years old and short-lived, but there is a much smaller number of ancient lakes, tectonic in origin and often millions of years old, that are scattered across every continent but Antarctica: Baikal, Tanganyika, Victoria, Titicaca, and Biwa, to name a few. Often these lakes are filled with a diversity of fish, crustaceans, snails, and other creatures found nowhere else in the world. In Our Ancient Lakes, Jeffrey McKinnon introduces the remarkable living diversity of these aquatic bodies to the general reader and explains the surprising, often controversial, findings that the study of their faunas is yielding about the formation and persistence of species.

The first single-authored volume to synthesize studies of ancient lakes, Our Ancient Lakes provides an overview of the lakes and their distinctive geological origins; accounts of the evolutionary processes that have generated the incredible diversity found in the lakes and produced some of the fastest speciation rates known for vertebrates; the surprisingly important role of interspecies mating in the most rapid diversifications; the uniquely complete records of the creatures that inhabited the lakes, which are being extracted from deep lake sediments; the prospects for the lakes as we tumble into the Anthropocene; and much more.

Shining a light on a class of biodiversity hot spot that is equivalent to coral reefs in the ocean or tropical rainforests on land, Our Ancient Lakes chronicles in a refreshingly personal and accessible way the often singular wonders of these venerable water bodies.
