Field heterogeneity of soil texture controls leaf water potential spatial distribution predicted from UAS-based vegetation indices in non-irrigated vineyards
Authors: Delval Louis , Bates Jordan , Jonard François , Javaux Mathieu
Published: January 2025

Abstract. Grapevine water status exhibits substantial variability even within a single vineyard. Understanding how edaphic, topographic, and climatic conditions impact grapevine water status heterogeneity at the field scale, in non-irrigated vineyards, is essential for winemakers as it significantly influences wine quality. This study aimed to quantify the spatial distribution of grapevine leaf water potential (Ψleaf) within vineyards and to assess the influence of soil property heterogeneity, topography, and climatic conditions on intra-field variability in two non-irrigated vineyards during two viticultural seasons. By combining multilinear vegetation indices from very-high-spatial-resolution multispectral, thermal, and lidar imageries collected with uncrewed aerial systems (UASs), we efficiently and robustly captured the spatial distribution of Ψleaf across both vineyards on different dates. Our results demonstrated that in non-irrigated vineyards, the spatial distribution of Ψleaf was mainly governed by the within-vineyard soil hydraulic conductivity heterogeneity (R2 up to 0.81) and was particularly marked when the evaporative demand and the soil water deficit increased, since the range of Ψleaf was greater, up to 0.73 MPa, in these conditions. However, topographic attributes (elevation and slope) were less related to grapevine Ψleaf variability. These findings show that the soil property within-field spatial distribution and climatic conditions are the primary factors governing Ψleaf heterogeneity observed in non-irrigated vineyards, and their effects are concomitant.

Published: January 2025

Abstract. Biogenic isoprene emissions play an important role in air quality so it is important to quantify their response to extreme events such as drought. While there have been some efforts to reduce uncertainties in isoprene emissions under the drought conditions, the effort has not been made in the South Korean region. Here, we aimed to constrain drought stress on biogenic isoprene emissions in South Korea using satellite formaldehyde (HCHO) column, the key product of isoprene oxidation, and a chemistry transport model (GEOS-Chem) with Model of Emissions of Gases and Aerosols from Nature version 2.1 (MEGAN2.1). It was found that the HCHO column from the Ozone Monitoring Instrument (OMI) increased by 5.4 % under the drought condition compared to the normal condition, but GEOS-Chem simulated a 20.23 % increase indicating an overestimation of isoprene emissions under drought. We implemented two existing drought stress algorithms in MEGAN2.1 and found they were not effective to reduce HCHO column biases in South Korea because those algorithms were proposed and developed for the Southeast United States (SE US). To improve this, we applied an iterative finite difference mass balance (IFDMB) method to estimate isoprene emissions using the OMI HCHO column. With this method, isoprene emissions were reduced by 60 % under the drought conditions compared to those simulated by the standard MEGAN2.1 implemented in GEOS-Chem. The increase of HCHO column under the drought conditions compared to the normal condition was also reduced to 10.71 %, which is comparable to that in the satellite retrievals. Based on isoprene emission difference between MEGAN2.1 and IFDMB, we developed the empirical equations to adjust isoprene emissions in South Korea that also improved model prediction of the secondary pollutant such as ozone.

Published: January 2025

Abstract. Seagrass meadows are vital carbon sinks, but their function is threatened by rapid decline, driving restoration efforts to enhance coastal recovery and carbon removal. The capacity of these restored seagrass as carbon sources or sinks depends largely on organic carbon metabolism and carbonate dynamics. In this study, we employed ex situ core incubation to investigate the metabolic rates of replanted seagrasses (SG), including gross primary productivity (GPP), community respiration (R), net ecosystem metabolism (NEM), and net ecosystem calcification (NEC) in SG and surrounding bare sediments (BS). SG exhibited higher GPP (26.0 ± 1.0 mmol O2 m-2 h-1 vs 0.7 ± 0.1 mmol O2 m-2 h-1) and NEM (208.2 ± 6.3 mmol O2 m-2 d-1 vs 20.1 ± 2.8 mmol O2 m-2 d-1) than BS, indicating their potential as carbon sinks by shifting benthic metabolism towards a more autotrophic state. In contrast, SG showed higher daytime carbonate production and nighttime carbonate dissolution, which could offset each other, resulting in no significant difference in NEC between SG and BS. In summary, our results found that the SG exhibited significantly higher NEM compared to BS, while no significant difference was found for NEC. Consequently, the net effect on the carbon uptake capacity of the restored seagrass is likely increased, primarily due to the higher NEM. Our findings highlight the ecological significance of seagrass restoration in mitigating climate change through carbon removal. Ex situ core incubation method allows for the simultaneous measurement of organic and inorganic carbon metabolism. While ex situ core incubation enhances feasibility, in situ assessments are still necessary to validate the results and ensure a comprehensive understanding of seagrass ecosystem dynamics.
Technical note: 21Ne in the CoQtz-N quartz standard material
Authors: Balco Greg
Published: January 2025

Abstract. Intercomparison standards produced from mineral samples exposed to the natural cosmic-ray flux are routinely used for interlaboratory comparison and normalization of measurements of the cosmogenic noble gases 3He and 21Ne. This effort is facilitated by availability of multiple standard materials with a wide range of cosmogenic-nuclide concentrations. The 'CoQtz-N' quartz standard, which was originally produced and distributed as an intercomparison standard for cosmogenic 10Be and 26Al, has a relatively low cosmogenic-nuclide concentration compared to other mineral standards used for cosmogenic noble gas analysis, and is therefore potentially useful for assessing linearity of interlaboratory offsets across a wide range of concentrations. This paper reports 21Ne analysis of 13 aliquots of CoQtz-N, interspersed with 14 aliquots of the commonly used CRONUS-A quartz standard, in three analytical sessions on two noble gas mass spectrometer systems. The excess 21Ne concentration in CoQtz-N, normalized to the accepted value of 320 x 106 atoms g-1 for CRONUS-A, is 13.87 ± 0.24 x 106 atoms g-1.
Water chemistry and greenhouse gas concentrations in waterbodies of a thawing permafrost peatland complex in northern Norway

Published: January 2025

Abstract. Thermokarst ponds in thawing permafrost landscapes play a considerable role in greenhouse gas (GHG) emissions despite their small size, yet they remain underrepresented in Earth system models. At the Iškoras site in northern Norway, a peat plateau with decaying permafrost and thermokarst ponds adjacent to a wetland, we studied water chemistry, dissolved organic matter (DOM) processing, and GHG fluxes over two years. Thermokarst ponds exhibited low pH, high organic acidity, and high oversaturation of dissolved carbon dioxide (CO2) and especially high dissolved methane (CH4). Adjacent wetland streams, however, with near-neutral pH, showed lower CH4 and organic acidity but significantly higher CO2 emissions despite moderate saturations driven by turbulence and bicarbonate replenishment. By contrast, CO2 emissions in ponds were primarily linked to DOM mineralization. DOM mineralization rates were similar between ponds and streams, suggesting that environmental factors like pH and microbial community differences counteract DOM lability variations. As permafrost decays and transitions from peat plateaus to wetlands, ponds as hotspots of CH4 emissions will disappear. However, total GHG fluxes across the peatland-wetland continuum will depend on wetland emissions, where CH4 emissions usually are considerable, and the fate of organic matter within the plateau. Lateral DOC fluxes may represent a significant loss of soil organic carbon, highlighting the importance of hydrological connectivity in linking terrestrial and aquatic systems. This study emphasizes the need to account for the relationship between hydrological and chemical processes when assessing C and GHG fluxes in permafrost-impacted regions.

Published: January 2025

Abstract. Aerosol typing is essential for understanding atmospheric composition and its impact on the climate. Lidar-based aerosol typing has been often addressed with manual classification using optical property ranges. However, few works addressed it using automated classification with machine learning (ML) mainly due to the lack of annotated datasets. In this study, a high-vertical-resolution dataset is generated and annotated for the University of Granada (UGR) station in Southeastern Spain, which belongs to the European Aerosol Research Lidar Network (EARLINET), identifying five major aerosol types: Continental Polluted, Dust, Mixed, Smoke and Unknown. Six ML models – Decision Tree, Random Forest, Gradient Boosting, XGBoost, LightGBM and Neural Network- were applied to classify aerosol types using multiwavelength lidar data from EARLINET, for two system configurations: with and without depolarization data. LightGBM achieved the best performance, with precision, recall, and F1-Score above 90 % (with depolarization) and close to 87 % (without depolarization). The performance for each aerosol type was evaluated and dust classification improved by ~30 % with depolarization, highlighting its critical role in distinguishing aerosol types. Validation against an independent dataset from a Saharan dust event confirmed robust classification under real and extreme conditions. Compared to NATALI, a neural network-based EARLINET algorithm, the approach presented in this work shows improved aerosol classification accuracy, which emphasize the benefits of using high-resolution multiwavelength lidar data from real measurements. This highlights the potential of ML-based methods for robust and accurate aerosol typing, establishing a benchmark for future studies using multiwavelength lidar at high-resolution data from EARLINET.

Abstract. Simulations of the coupled ionosphere–magnetosphere system are a key tool to understand geospace and its response to space weather. For the most part, they are based on fluid descriptions of plasma (magnetohydrodynamics, MHD) formalism, coupled to an electrostatic ionosphere. Kinetic approaches to modeling the global magnetosphere with a coupled ionosphere system are still a rarity. We present an ionospheric boundary model for the global near-Earth plasma simulation system Vlasiator. It complements the magnetospheric hybrid-Vlasov simulations with an inner boundary condition that solves the ionospheric potential based on field-aligned current and plasma quantities from the magnetospheric domain. This new ionospheric module solves the ionospheric potential in a height-integrated approach on an unstructured grid and couples back to the hybrid-kinetic simulation by mapping the resulting electric field to the magnetosphere's inner boundary. The solver is benchmarked against a set of well-established analytic reference cases, and we discuss the benefits of a spherical Fibonacci mesh for use in ionospheric modeling. Preliminary results from coupled global magnetospheric–ionospheric simulations are presented, showing formation of both Region 1 and Region 2 current systems.
Field comparison of load-based wind turbine wake tracking with a scanning lidar reference
Authors: Onnen David , Larsen Gunner Christian , Lio Alan Wai Hou , Hulsman Paul , Kühn Martin , Petrović Vlaho
Published: January 2025

Abstract. Wind farm control concepts require awareness and observation methods of the inner-farm flow field. The relative location of the wake, to which a downstream turbine is exposed, is of high interest. It can be used as feedback to support closed-loop wake-steering control, ultimately leading to higher power extraction and fatigue load reduction. With increasing fidelity, not only time-averaged wakes but also instantaneous wake conditions, subject to meandering and wind direction changes, are considered within a controller. This paper presents a quantitative field comparison of two independently applied wake centre estimation methods: a scanning lidar and an Extended Kalman Filter (EKF) based on the rotor loads of the waked turbine. No ground truth is available in the field environment, therefore the methodology accounts for the fact that two uncertain estimates are compared. The lidar estimates, with a derived uncertainty in the order of 0.05 rotor diameters D, can be used as a suitably precise reference to draw conclusions regarding the load-based EKF. The EKF uses Coleman-transformed blade root bending moments, linked to the wake centre position via an analytical model with a low number of tuning parameters. The model can easily be trained with aeroelastic simulations including the Dynamic Wake Meandering model. The formulation adds robustness to the tracking and allows to determine the confidence in the wake position estimate, which can be used for wake impingement detection or for a wake-steering controller to judge whether a yaw manoeuvre is adequate. The results indicate agreement of the methods with root-mean-square errors of 0.2 D for low and moderate turbulence intensity, and 0.3 D for turbulence intensities above 12 %. The paper focuses on wake position estimation but also outlines a methodology, how wind farm models or wind field reconstruction techniques can be validated with complementary lidar data.

Published: January 2025

Alinhando-se aos pressupostos teórico-metodológicos da Sociolinguística Variacionista (WEINREICH; LABOV; HERZOG, 2006; LABOV, 2008), analisamos o efeito de fatores estilísticos na variação das formas pronominais tu, você e cê em função sintática de sujeito. Para tanto, utilizamos uma amostra constituída por 24 entrevistas sociolinguísticas realizadas com falantes ilheenses. Controlamos as variáveis estilísticas tipo de assunto, grau de familiaridade com o assunto, tipo de discurso e tipo de sequência discursiva. Para realizarmos o tratamento estatístico, submetemos os dados do fenômeno à plataforma R em Interface com o RStudio (R CORE TEAM, 2021). Constatamos 938 ocorrências do fenômeno variável, sendo 70,6% da forma você, 27,9% da forma cê e 1,5% da forma tu, evidencia-se, assim, que se trata de um fenômeno linguístico variável no falar ilheense. Os resultados evidenciaram que: a forma pronominal você, na amostra analisada, é mais frequente em todos os níveis dos fatores controlados; a forma cê, teve seu uso motivado pelos contextos de assuntos de vivências pessoais, mais familiaridade com o assunto, relato próprio e em sequências Injuntivas. Tais resultados Indiciam que a variante você transita por situações tanto de formalidade quanto de Informalidade, já a variante cê tende a ser utilizada pelos ilheenses em situações menos formais.

Performing political reparation: Public service interpreters’ dispersed practices for social justice
Authors: Giustini Deborah
Published: January 2025

This study examined the activities of spoken-language public service interpreters who are engaged in supporting social justice and marginalized communities across a variety of institutional settings in the United Kingdom. By drawing on a practice theory approach, it argues that public service interpreters’ ad-hoc social and communicative activities in and beyond interpreted encounters are practices of “dispersed activism”. Although lacking the organized and collective character that characterizes a social movement, dispersed activism can work towards changing unjust systems. Based on a dataset of qualitative interviews, the study revealed a group of public service interpreters as architects of political reparation who shape both communication interactions and their own professional conduct towards localized societal transformation in power-laden settings. In addition to conceptualizing public service interpreting activism as non-formalized equity-oriented practices, the study reveals how aiming at social justice imposes challenges on the interpreters’ emotional, bodily, and material involvement, with implications for the negotiation of norms of neutrality and non-engagement.
“I know – that’s the system. The system is wrong”: Allyship and social justice in community interpreting from a service-user perspective
Authors: Marianacci Agustina
Published: January 2025

Defined as the practice of gaining awareness and acting upon the oppression of marginalized groups, allyship can account for the power interpreters hold in systems of oppression and can contribute to social justice. This article reports on a study designed to explore allyship in spoken-language interpreting from the perspective of culturally and linguistically diverse (CALD) users of interpreting services. Involving CALD individuals – foreign-born people in English-speaking countries who do not speak English at home – from the Latin American community living in Aotearoa New Zealand, the study explored users’ perspectives on the role of interpreters, their perceptions of allyship and social justice, and the way these concepts inform interpreting practice. The study employed a culturally affirming horizontal methodology that relied on four one-on-one dialogues with users of Spanish-speaking interpreting services about their experiences in various community settings. This was followed by one group dialogue involving users, English–Spanish interpreters and a community representative. The findings suggest that users prefer humane and caring interpreters with a flexible understanding of their role. Aware that social marginalization is intrinsic to community interpreting, they highlighted the reality that mere message transfer and language proficiency are insufficient for CALD individuals to secure access to statutory services and that inadequate assistance can be (re-)traumatizing. The users’ perspective therefore conflicts with the prevailing rules-based approach to ethics in interpreting and its focus on accuracy in interpreting over social and relational skills. To overcome the disparity between users’ expectations and entrenched concepts of neutrality and non-intervention, allyship stands as a potential lens through which to develop a nuanced and flexible understanding of the community interpreter’s role, as well as culturally grounded redefinitions of ethicality and professionalism in the field.

Translation for social justice: concepts, policies, and practices across modalities and contexts
Authors: Boeri Julie
Published: January 2025

The transnational nature of contemporary movements, media and networks in our globalised and interconnected societies has placed translation at the heart of counter-hegemonic discourses and endeavours. In this context, translation has become a powerful prism through which to think about and practise social justice. Although largely intellectualised in relation to Western liberal welfare states, social justice is also a performative and interpersonal prism of social change with roots historically spread across cultures, traditions and territories and with ramifications in contemporary forms of resistance. Thus, whereas social justice has traditionally been understood as the fair distribution of means and resources and the recognition of people’s rights across status in a given society, the increasing interconnection of struggles across the world has broadened social justice in ways that raise the stakes of translation. The leveraging and enactment of the multiple rights which social justice now encompasses is contingent on the organisation, the practice and the theorisation of translation in all its modalities (translation, interpreting, bilingual facilitation, fixing, subtitling, dubbing) and across communication contexts of resistance (social movements, media networks, cultural institutions). This special issue of the journal explores social justice by delving into specific areas and modalities of translation and interpreting practices. At the same time, it engages with macro-societal issues that affect these practices. These issues range from the power (and the limitations) of translation in circulating counter-hegemonic ideas and knowledge across borders in the publishing, media and cultural industries to the development of curricular, pedagogical and policy-making strategies in a higher education system that is both technologically disrupted and ableist-structured. The issues also include the public institutions’ exclusionary communication practices inherited from colonialisation, patriarchy, and ableism, and the subsequent expectations and actual practices of language professionals’ support to migrants and other vulnerable citizens in this context. The contributions gathered in this special issue contribute to expanding the boundaries of the constantly evolving field of translation while deepening our reflection on the ways in which education, research and practice may reproduce, contest and disrupt systemic injustices.
The Role of Accreditation in Transforming IAIN Lhokseumawe's PAI Quality
Authors: Wardhani Nia , Safitri Maya , Iqbal Muhammad
Published: January 2025

This study aims to analyze the implementation of accreditation in improving the quality of education in the Postgraduate Islamic Religious Education (PAI) Study Program at IAIN Lhokseumawe. Higher education accreditation is an important instrument to ensure the quality of education that is relevant to the needs of society and the development of the times. However, the implementation of accreditation often faces various challenges, such as the fulfillment of diverse quality standards and limitations in the management of accreditation data. The research method used is a qualitative approach with data collection techniques through interviews, observations, and document analysis. This study found that the Postgraduate PAI Study Program has tried to meet accreditation standards by improving the quality of the curriculum, management, and human resources. However, there are obstacles in the integration of internal and external quality evaluations and data management that still lack innovation. These findings suggest that accreditation should be seen as a strategic tool for a more holistic transformation of education, not just an administrative formality. This research is expected to contribute to improving the implementation of accreditation in higher education institutions, especially in Islamic-based study programs.

Published: January 2025

Motor Induksi 3 Phase merupakan konversi energi listrik menjadi energi mekanik yang terdiri atas stator dan rotor. Efisiensi kerja dari motor induksi merupakan rasio dari energi listrik yang digunakan motor induksi lalu diubah menjadi energi mekanis serta sedikitnya rugi-rugi daya pada motor induksi daripada semua energi yang digunakan. Pada tanggal 6 Juni 2024 di Palembang Indah Mall terjadi ketidakstabilan tegangan pasca terjadinya Blackout total dari PLN di Sumatera Selatan,  sehingga mempengaruhi kinerja motor induksi yang digunakan untuk penggerak fan pada cooling tower, karena ketidakstabilan tegangan yang diterima motor induksi tersebut sehingga terjadi penurunan dari segi torsi serta efisiensi motor induksi. Pada penelitian kali ini, diketahui besar nilai eff untuk tegangan 375 V adalah 0,86; untuk efisiensi pada tegangan 400 V adalah 0,81; dan untuk efisiensi pada tegangan 415  V adalah 0,77. Dari pernyataan tersebut bisa kita simpulkan bahwa semakin besar tegangan, maka akan semakin kecil efisiensi motor induksi 3 phase. Tegangan yang normal sangat dibutuhkan untuk menjaga efisiensi motor induksi 3 phase selalu dalam keadaan baik.

Published: January 2025

The Italian Mediterranean Buffalo is the most important buffalo’s breeds for milk production and its derivatives, which has a selection program implemented more than 20 years ago. The selection is based on an aggregate index that includes dairy, mozzarella yield, and functional traits. The improvement of udder conformation (UC) traits is an aspect that plays an essential role in udder health and longevity; it is of great interest due to its direct relationship with economic losses caused by mastitis or poor milkability. The aim of this study was the development of an aggregate selection index (ASI) considering MP (milk production), MSCS150 (geometric mean of somatic cell score at 150 days in milk), and UC traits (fore udder attachment– FUA; rear udder width– RUW; rear legs height– RLH; teat direction – TD; teat length – TL and teat position – TP). The first step was to estimate the genetic (co)variances between the UC, MP, and MSCS150 traits and to estimate the relative weight for each UC trait. The phenotypic records of 15,275 females and a pedigree with 43,395 animals were used. A multitrait animal model that included CG (herd-year-calving season), calving month, and parity as fixed effects, and the animal as a random effect was used. The estimated heritability for MP and MSCS150 were 0.391 and 0.134, respectively, and varied between 0.11 and 0.23 for UC traits. Low negative genetic correlations were observed between MP and RLH (−0.119), the same pattern between MSCS150 and RLH (−0.350) and MSCS150 and FUA (−0.220). A positive correlation was found between FUA and MP (0.4272) and MP and RUW (0.645). Using ASI as selection criteria, an annual reduction of −0.03 is expected for MSCS150 and an increase of 0.26 kg for MP. During a selection period of ten years, the expected cumulative genetic gains would be -0.32 for MSCS150 and an increase of MP in 2.57 kg. Selective breeding programs aim to improve specific traits over time by selecting individuals with desirable genetic characteristics as parents of the next generation. According to the results, by focusing on RUW, RLH, and TD traits, genetic improvements are expected to lead to reduced severity of MSCS150 while maintaining or increasing milk production.
Association of Neospora caninum and abortions in water buffaloes in Venezuela
Authors: Pérez-Gil Rosaura , Ramírez Fernando
Published: January 2025

Buffaloes are an important natural host of Neospora caninum; this protozoan causes abortions in bovines. In addition, transplacental transmission is considered the main route of transmission. This research aimed to study the seroprevalence of N. caninum of 223 Bubalus bubalis females; the herd comes from 10 farms in 4 states of Venezuela; in addition, the association between the presence of antibodies against N. caninum with parity and the history of abortions was analyzed. The data was extracted from the SG Software Ganadero version 23, exported to Excel version 2306, and analyzed with IBM SPSS Statistics 20. Antibodies were determined by ELISA using a commercial kit (IDEXX® ). The cut-off value to define positive cases was the coefficient sample/positive ≥ 0.500. A chi-square test was performed to estimate the association between the presence of antibodies against N. caninum with parity and abortions. Of the 223 animals analyzed, 59.2% of the samples were positive for N. caninum antibodies. The percentages of seropositive animals were: 4.0%, 66.4%, 13.0%, 9.0%, 1.8%, 0.4%, 1,3%, and 4% for animals with 0 to 7 calving, respectively. The percentages of positives to N. caninum for buffaloes of parity 1 and 2 were 54.05% and 62.06%, respectively (X2 = 0.630, p=0.427), while the percentage of positives to N. caninum in buffaloes without abortion and with one previous abortion were 54.17% and 74.51%, respectively (X2 = 6.68, p=0.01). In addition, buffaloes with a history of abortion had more odds of being seropositive to N. caninum than those without abortions (2.478, 95%CI:1.2874-4.8834, p = 0.0087). Therefore, it is concluded that N. caninum serology and parity are independent, while N. caninum serology and the occurrence of abortions are associated. These results demonstrate that N. caninum is a risk factor for the occurrence of abortions in water buffaloes, so it is suggested to include this pathology in preventive health programs in herds.

The disposal of plastic film is a global problem that generates much pollution. The full use of waste from the food industry brings numerous benefits, including sustainable practices. Using films made with natural antioxidants derived from agro-industrial waste is considered an alternative to minimize these impacts. Given this context, this study aimed to develop and characterize films based on guava (Psidium guajava) peel flour for active food packaging. The films presented low thickness and solubility in water, proving to be a barrier to water vapor and suitable for maintaining the integrity of foods added to them. Moreover, their elasticity and resistance proved to be moderate and their moisture content is high due to the presence of large amounts of phenolic compounds from guava peel flour (320.58 ± 81.1 mg gallic acid/100 g sample), resulting in clear, slightly greenish-yellow films, which present their best effect as active antioxidant packaging to be applied in alcoholic foods (36 μmol Trolox/g), followed by use in acidic foods (17.2 μmol Trolox/g). This study demonstrated the potential for applying guava residue as a raw material for producing biodegradable films, proposing a purpose for the peel of this fruit.

Kefir is a naturally carbonated and mildly acidic milk beverage fermented by grains that consist of bacteria and yeast living in a symbiotic relationship. Its unique flavor arises from a blend of lactic acid, ethanol, carbon dioxide, and other compounds produced by the microorganisms within the kefir grains. The microorganisms in kefir are a complex microbial population that varies by geographical region. Kefir is widely acknowledged for its probiotic content, with reported health benefits that include modulation of intestinal microflora, immune system stimulation, and antimicrobial, antineoplastic, hypocholesterolemic, antidiabetic, and antimutagenic effects. It also exhibits β-galactosidase activity and benefits lipid and blood pressure levels. This review focuses on the microbiological aspects, composition, and production of milk kefir, highlighting how its biological properties correlate with the health benefits associated with its consumption.
Introduction

The Future of the Past
Authors: Kahane Ahuvia
Published: January 2025

This paper considers the temporality and ethics of democracy, specifically within the context of Pericles’ funeral oration in Thucydides’ History of the Peloponnesian War. Drawing on J. Derrida’s notions of the future-to-come and democracy, reading the oration through the work of Gomm, opposing conservative Anglo-American readings and invoking the political thought of J. Rancière as well as insights from E. Schrödinger, K. Barad and the sciences, the paper argues that democracy, and indeed Pericles’ Athenian democracy is a practice that is the unity of the “one too many” and “the ‘more, always more’ of unsatisfied desire”, a regime that, as Rancière puts it, is “governed by the judicious use of its own un-governability.”
Before and after Greece and Egypt in the Eighteenth Century
Authors: Orrells Daniel
Published: January 2025

This chapter examines the question of the historical relationship—the before and the after—of ancient Greece and Egypt in the eighteenth century, to complicate our narratives about the rise of philhellenism during the Enlightenment. While the eighteenth-century antiquarian turn to material culture has indeed been seen as foundational—the “before”—for the development and institutionalization of the discipline of classics, we will see that the emerging narrative about Europe’s ancient Greek origins was constructed in dialogue with eighteenth-century debates about the Egyptian hieroglyph, the history of writing, and the relationship between image and text. This chapter explores these issues by focussing on an exemplary set of Enlightenment intellectuals and antiquarians: Giambattista Vico, Winckelmann, and d'Hancarville. This chapter shows that the reception of ancient Egypt in the Enlightenment was fundamental to the emergence of the European narrative about its Hellenic origins.

Do global value chains and local capabilities matter for economic complexity in EU regions?
Authors: Boschma Ron , Hernández Rodríguez Eduardo , Morrison Andrea , Pietrobelli Carlo
Published: January 2025

This paper combines insights from the literatures on Global Value Chains (GVC), Economic Complexity and Evolutionary Economic Geography to assess the role of GVC participation and regional capabilities in fostering economic complexity in EU NUTS-2 regions. Our results suggest there is no such thing as a common path towards economic complexity across EU regions. Low-income regions manage to benefit from both regional capabilities and GVC participation. In contrast, high-income regions rely more on their existing local capabilities rather than on GVC participation.

This desk review evaluates the current state of interventions for mental health and cognitive functioning among older adults in Switzerland focusing on the features of these interventions as well as on Swiss-specific contextual factors that contribute to vulnerability and stigma. The goal is to guide the development of effective, evidence-based interventions and policies to ensure that older adults in Switzerland not only live longer but also enjoy better mental health and cognitive functioning. We searched PubMed, PsycINFO, and Scopus for eligible studies from January 2018 until October 2024. We included studies investigating interventions targeting mental health and/or cognitive functioning in older adults living in Switzerland. In addition, we searched for gray literature reporting on cognitive and mental health interventions, as well as mental health, cognitive functioning, stigmatization, and stigma mitigation strategies in the Swiss context. Core features of the interventions (intervention type, efficacy, delivery modes, recruitment, stigma-related aspects) and target populations (groups at risk of vulnerability, stigma sources) were extracted, descriptively summarized, and discussed. A comprehensive search resulted in 1200 records, with 26 peer-reviewed articles and five gray literature reports meeting the inclusion criteria. The findings suggest that individualized multidomain interventions, including behavioral change techniques and multifaceted stigma-mitigating strategies, might be required to sustainably improve mental health in older adults.
