Coordination among flower pigments, scents and pollinators in ornamental plants
Authors: Shen Yuxiao , Rao Yufei , Ma Mengni , Li Yajun , He Yanhong , Wang Zheng , Liang Mei , Ning Guogui 
Published: February 2024

AbstractFlower color and scent, crucial qualitative characteristics of ornamental plants, display extensive variation. These distinct pigments and scents play a key role in attracting specific pollinators. While previous research primarily delved into the synthetic regulatory mechanisms of individual traits and their respective attraction to insects, recent studies unveil an interconnectedness between flower color and scent through transcriptional regulatory networks. Moreover, evidence suggests that both color and scent actively contribute to insect attraction. This review summarizes the co-regulation and synthesis of pigments and scents, highlighting their pivotal roles in pollinator attraction. The insights provided will serve as valuable references for applications in metabolic engineering, novel variety breeding, and insect and pest detection and management.
Child labour, school attendance and orphaned children in the Democratic Republic of the Congo

Published: February 2024

AbstractThis article contributes to the stock of scientific knowledge by showing the effect of orphan status on child labour and school attendance in the Democratic Republic of the Congo (DRC). While the abolition of child labour is undeniably one of the major tasks assigned to the International Labour Organization (ILO) when it was founded, child labour remains a severe problem worldwide. In many parts of the world, especially in developing countries, children do not have access to school. Instead of ending up in school, millions of children are forced to engage in child labour in income-generating and non-income-generating activities. Little researchers have yet made it possible to obtain simultaneous information on child labour, school attendance and orphaned children. This paper describes the research that tries to make such a connection. Data used is from the out-of-school children and adolescents (OOSC-DRC-2012) survey organised by the Ministry of Primary, secondary and Vocational Education. Using a bivariate probit econometric model and testing the endogeneity with an instrumental variables approach, funding of the analysis supports the assumption of a significant negative relationship between child labour and school attendance. The result shows also that being orphaned reduces a child's likelihood of school attendance and increases the probability of entering the labour market. It is underlined that most children are present in non-income-generating than income-generating activities.
Silenced voices and strained livelihoods: challenges faced by Kashmiri women entrepreneurs after article 370 abrogation
Authors: Mohsin Abdul , Muzaffar Sabahat 
Published: February 2024

Abstract
Objective
This research endeavours to elucidate the ramifications of the communication blockade on women entrepreneurs operating within the Kashmir Valley in the wake of the protracted imposition of communication blockade in the region of Jammu and Kashmir following the unanticipated abrogation of Article 370 of the Constitution of India.

Participants
The study assembled a cohort of 20 women entrepreneurs hailing from Srinagar and Ganderbal districts in Kashmir, utilising a combination of purposive and snowball sampling methodologies to ensure a comprehensive representation of participants. Data acquisition was carried out through a series of direct, semi-structured, and in-depth personal interviews.

Method
Employing an interpretive phenomenological approach, this qualitative inquiry transcribed the rich narratives gleaned from these interviews, elucidating a confluence of recurrent themes.

Results
The protracted absence of communication channels, extending indefinitely, precipitated a multifaceted crisis encompassing economic, social, and psychological dimensions, thereby significantly impacting the well-being of residents of the erstwhile state of Jammu and Kashmir.

Conclusion
The recurring themes encompass anger and frustration, loss of livelihood, helplessness and dehumanisation stemming from total communication blackouts.
The Archaeology of Pharaonic Egypt
Authors: Bussmann Richard 
Published: February 2024

In this book, Richard Bussmann presents a fresh overview of ancient Egyptian society and culture in the age of the pyramids. He addresses key themes in the comparative research of early complex societies, including urbanism, funerary culture, temple ritual, kingship, and the state, and explores how ideas and practices were exchanged between ruling elites and local communities in provincial Egypt. Unlike other studies of ancient Egypt, this book adopts an anthropological approach that places people at the centre of the analysis. Bussmann covers a range of important themes in cross-cultural debates, such as materiality, gender, non-elite culture, and the body. He also offers new perspectives on social diversity and cultural cohesion, based on recent discoveries. His study vividly illustrates how our understanding of ancient Egyptian society benefits from the application of theoretical concepts in archaeology and anthropology to the interpretation of the evidence.
Panem et circenses: removing political news to generate electoral support, evidence from Berlusconi's Italy
Authors: De Angelis Andrea , Vecchiato Alessandro 
Published: February 2024

AbstractThis paper examines the strategic use of public news media – specifically television (TV) – as an instrument of political influence, focusing on Italy's 2011 financial crisis under Berlusconi's premiership. Using an original large corpus of over 20,000 hours of televised news transcripts and a quasi-experimental design, we investigate how political influence altered media coverage and, subsequently, public opinion and electoral outcomes. Our difference-in-differences analysis, complemented by unsupervised text scaling of news content, reveals a significant shift from “hard” political news to “soft” news on public TV during Berlusconi's tenure. Findings suggest a deliberate reduction in hard news coverage by an average of 107 seconds daily, which significantly increased voter support for Berlusconi's party. In the conclusions, we discuss the broader implications of our findings for media independence in Western democracies amid the emergence of artificial intelligence-generated news contents and the prevalence of algorithmically tailored news feeds.

Fascist transnationalism during the occupation of Albania (1939–43)
Authors: Lang Alexander 
Published: February 2024

AbstractThis article links the study of transnational and imperial fascism in the context of the Italian occupation of Albania by examining how Italian authorities sought to turn Albanians abroad into assets rather than liabilities. Organising and monitoring Albanians occurred through conferences, youth institutions and consular activities. Studying such concrete contacts and negotiations allows us to explore the practical issues latent in expanding fascist political subjectivity in transnational and imperial contexts. On the one hand, Italians hoped to verse Albanians in a fascist identity by using existing organisational strategies while silencing or converting potential anti-Italian critics. On the other, many Albanians expressed and offered support for these Italian efforts, though with reservations and conditions, raising questions as to what it meant to be an Albanian nationalist and/or fascist in the years of occupation. The Albanian case therefore contributes to our understanding of the tensions inherent in ‘universalising’ fascism for colonial subjects.
Lauda Sion as Doxological Compendium of St. Thomas’s Eucharistic Theology
Authors: Hannon Urban 
Published: February 2024

AbstractIn 1264 in the town of Orvieto, St. Thomas Aquinas composed the Lauda Sion as the Mass sequence for Pope Urban IV’s new universal solemnity of the Body and Blood of our Lord Jesus Christ, the feast of Corpus Christi. The present paper will consider this text of St. Thomas’s liturgical sequence in relation to the eucharistic theology that he teaches in the Summa Theologiae. Just as, according to the Dionysian Aquinas, the Psalms contain all the doctrines revealed in the rest of scripture but transposed into the highest literary genre of praise, so the Lauda Sion contains all the essential eucharistic doctrines of the Summa Theologiae, now set in that same laudatory genre as the Psalter. The paper is divided into ten sections, corresponding to the questions in St. Thomas’s treatment of the Holy Eucharist in the Tertia Pars. Proceeding one topic at a time, this paper will show how the Lauda Sion serves as a doxological compendium of St. Thomas Aquinas’s whole eucharistic theology.

Published: February 2024

AbstractBackgroundElucidation of the interaction of biological and psychosocial/environmental factors on opioid dependence (OD) risk can inform our understanding of the etiology of OD. We examined the role of psychosocial/environmental factors in moderating polygenic risk for opioid use disorder (OUD).MethodsData from 1958 European ancestry adults who participated in the Yale-Penn 3 study were analyzed. Polygenic risk scores (PRS) were based on a large-scale multi-trait analysis of genome-wide association studies (MTAG) of OUD.ResultsA total of 420 (21.1%) individuals had a lifetime diagnosis of OD. OUD PRS were positively associated with OD (odds ratio [OR] 1.42, 95% confidence interval [CI] 1.21–1.66). Household income and education were the strongest correlates of OD. Among individuals with higher OUD PRS, those with higher education level had lower odds of OD (OR 0.92, 95% CI 0.85–0.98); and those with posttraumatic stress disorder (PTSD) were more likely to have OD relative to those without PTSD (OR 1.56, 95% CI 1.04–2.35).ConclusionsResults suggest an interplay between genetics and psychosocial environment in contributing to OD risk. While PRS alone do not yet have useful clinical predictive utility, psychosocial factors may help enhance prediction. These findings could inform more targeted clinical and policy interventions to help address this public health crisis.
Period–Luminosity Relations in the Local Group of Galaxies
Authors: Soszyński Igor 
Published: February 2024

AbstractLocal Group galaxies, particularly the Large and Small Magellanic Clouds, have historically played and continue to play a unique role in studies of the period–luminosity (PL), period–luminosity–color (PLC), and period–Wesenheit (PW) relations, not just for pulsating stars. In recent years, significant efforts have been devoted to calibrate the PL, PLC, and PW relationships at different wavelengths, including studies of the influence of metallicity and nonlinearities on the accuracy of measured distances. However, the PL diagram has many more astrophysical applications. It serves as a vital tool for classifying different types of pulsating stars and can even facilitate the discovery of new classes of variable stars. Moreover, it aids in distinguishing among various modes of pulsation, facilitates the identification of pulsating stars that are members of binary systems, and enables studies of the three-dimensional structures of neighboring galaxies. In this contribution, I present the latest results on the PL, PLC, and PW relations obeyed by various types of variable stars in Local Group galaxies – from δ Scuti stars to Mira variabless and from close binary systems to the mysterious long secondary periods exhibited by red giant and supergiant stars.
A multi-wavelength analysis of BL Her stars: Models versus Observations

Published: February 2024

AbstractWe present new theoretical period–luminosity (PL) and period–radius (PR) relations at multiple wavelengths (Johnson–Cousins–Glass and Gaia passbands) for a fine grid of BL Herculis models computed using mesa-rsp. The non-linear models were computed for periods typical of BL Her stars, i.e. 1 ≤ P(days) ≤ 4, covering a wide range of input parameters: metallicity (−2.0 dex ≤ [Fe/H] ≤ 0.0 dex), stellar mass (0.5–0.8 ), luminosity (50–300 ) and effective temperature (full extent of the instability strip; in steps of 50K). We investigate the impact of four sets of convection parameters on multi-wavelength properties. Most empirical relations match well with theoretical relations from the BL Her models computed using the four sets of convection parameters. No significant metallicity effects are seen in the PR relations. Another important result from our grid of BL Her models is that it supports combining PL relations of RR Lyrae and Type II Cepheids together as an alternative to classical Cepheids for the extragalactic distance scale calibration.
Empirical constraints for the instability strip from the analysis of LMC Cepheids
Authors: Espinoza-Arancibia F. , Pilecki B. 
Published: February 2024

AbstractThe instability strip (IS) of classical Cepheids has been extensively studied theoretically. Comparison of the theoretical IS edges with those obtained empirically, using the most recent Cepheids catalogs available, can provide us with insights into the physical processes that determine the position of the IS boundaries. We investigate the empirical positions of the IS of the classical Cepheids in the Large Magellanic Cloud (LMC) using data of classical fundamental-mode and first-overtone LMC Cepheids from the OGLE-IV variable star catalog, together with a recent high-resolution reddening map from the literature. We studied their position on the Hertzsprung-Russell diagram and determined the IS borders by tracing the edges of the color distribution along the strip. We obtain the blue and red edges of the IS in V- and I-photometric bands, in addition to Teff and log L⊙. The results obtained show a break located at the Cepheids’ period of about 3 days, which was not reported before. This phenomenon is most likely explained by the depopulation of second and third crossing classical Cepheids in the faint part of the IS, since blue loops of evolutionary tracks in this mass range do not extend blueward enough to cross the IS at the LMC metallicity. Furthermore, our empirical borders show good agreement with theoretical ones published in the literature. This proves that our empirical IS is a useful tool to put constraints on theoretical models.
The Local Value of H0
Authors: Riess Adam G. , Breuval Louise 
Published: February 2024

AbstractWe review the local determination of the Hubble constant, H0, focusing on recent measurements of a distance ladder constructed from geometry, Cepheid variables and Type Ia supernovae (SNe Ia). We explain in some detail the components of the ladder: (1) geometry from Milky Way parallaxes, masers in NGC 4258 and detached eclipsing binaries in the Large Magellanic Cloud; (2) measurements of Cepheids with the Hubble Space Telescope (HST) in these anchors and in the hosts of 42 SNe Ia; and (3) SNe Ia in the Hubble flow. Great attention to negating systematic uncertainties through the use of differential measurements is reviewed. A wide array of tests are discussed. The measurements provide a strong indication of a discrepancy between the local measure of H0 and its value predicted by Λ Cold Dark Matter theory, calibrated by the cosmic microwave background (Planck), a decade-long challenge known as the ‘Hubble Tension’. We present new measurements with the James Webb Space Telescope of >320 Cepheids on both rungs of the distance ladder, in a SN Ia host and the geometric calibrator NGC 4258, showing good agreement with the same as measured with HST. This provides strong evidence that systematic errors in HST Cepheid photometry do not play a significant role in the present Hubble Tension. Future measurements are expected to refine the local determination of the Hubble constant.
Theoretical Stellar Pulsation Physics
Authors: Marconi M. , De Somma G. , Molinaro R. , Musella I. 
Published: February 2024

AbstractPulsating stars play a crucial role in the calibration of the cosmic distance scale as well as in tracing the properties of the associated stellar populations. In the era of large observational surveys and precise astrometric missions, it is crucial to rely on accurate stellar pulsation models able to predict the observed behaviors for different physical assumptions. Indeed, the relations currently used in the literature to derive individual and mean distances of mainly radially pulsating stars such as Cepheids and RR Lyrae are well physically understood, but are also known to depend on a number of often unknown parameters. Recent extensive sets of stellar pulsation models developed by various authors show how variations in the physical assumptions can affect the theoretical prediction of the instability strip boundaries, the morphology and amplitude of light and radial velocity curves, and the consequent Period-Luminosity, Period-Luminosity-Color and Period-Wesenheit relations. These aspects are discussed in the framework of current open problems in the field of classical pulsating stars.
Impact of the Gaia ESA mission on the primary Period–Luminosity Calibrators in the Milky Way: Cepheids and RR Lyrae
Authors: Clementini Gisella 
Published: February 2024

AbstractWe discuss the impact of Gaia, the cornerstone mission of the European Space Agency (ESA), on the calibration of the period–luminosity and luminosity–metallicity relations of Cepheids and RR Lyrae stars, with specific reference to data published as part of the most recent Gaia releases: Early Data Release 3 (EDR3), on 19 December 2020, and Data Release 3 (DR3) on 13 June 2022. We provide future perspectives for the Gaia mission, including extensions approved by ESA and a tentative schedule of the data releases that will take place in the next few years. We briefly present plans for cross-Coordination Unit processing of Gaia data of Cepheids and RR Lyrae stars for DR4 and conclude by outlining the expected improvement in astrometry at the end of the extended Gaia mission, which will help to further strengthen the calibration of the first rung of the cosmic distance ladder.
The Cepheid Extragalactic Distance Scale: Past, Present and Future
Authors: Freedman Wendy L. , Madore Barry F. 
Published: February 2024

AbstractCepheids have been the cornerstone of the extragalactic distance scale for a century. With high-quality data, these luminous supergiants exhibit a small dispersion in their Leavitt (period–luminosity) relation, particularly at longer wavelengths, and few methods rival the precision possible with Cepheid distances. In these proceedings, we present an overview of major observational programs pertaining to the Cepheid extragalactic distance scale, its progress and remaining challenges. In addition, we present preliminary new results on Cepheids from the James Webb Space Telescope (JWST). The launch of JWST has opened a new chapter in the measurement of extragalactic distances and the Hubble constant. JWST offers a resolution three times that of the Hubble Space Telescope (HST) with nearly 10 times the sensitivity. It has been suggested that the discrepancy in the value of the Hubble constant based on Cepheids compared to that inferred from measurements of the cosmic microwave background requires new and additional physics beyond the standard cosmological model. JWST observations will be critical in reducing remaining systematics in the Cepheid measurements and for confirming if new physics is indeed required. Early JWST data for the galaxy, NGC 7250 show a decrease in scatter in the Cepheid Leavitt law by a factor of two relative to existing HST data and demonstrate that crowding/blending effects are a significant issue in a galaxy as close as 20 Mpc.
The distance scale of Type II Cepheids from near-infrared observations in the Magellanic Clouds

Published: February 2024

AbstractWe employed data from the VISTA near-infrared YJKS survey of the Magellanic System to analyse the light curves of Type II Cepheids (T2Cs) in the Large and Small Magellanic Clouds (LMC and SMC, respectively). Using the T2Cs identified by the OGLE IV survey and Gaia mission, we built up a sample of about 330 pulsators belonging to both galaxies. For all these objects we obtained accurate intensity-averaged magnitudes in the YJKS bands by means of a template-fitting technique. We complemented our near-infrared data with optical photometry from the literature to calculate period-luminosity and period-Wesenheit relations for a variety of different bands and colour combinations and separately for the different T2C subclasses (BL Herculis, W Virginis, peculiar W Virginis, RV Tauri). These relations, calibrated with the LMC distance modulus, were tested using T2Cs belonging to Galactic globular clusters. We thus calculated the distances of 22 clusters and compared them with the literature values, mainly based on RR Lyrae stars, finding good agreement within 1 σ and dispersion of the order of 0.3 – 0.5 kpc, depending on the adopted period-luminosity/period-Wesenheit relation.
Measuring It, Managing It, Fixing It? Data and Rights in Transnational and Local Climate Change Governance
Authors: Mai Laura 
Published: February 2024

AbstractThe Paris Agreement, related intergovernmental decisions, and transnational climate change governance initiatives mobilize data as a means of measuring, managing, and addressing changing climatic conditions. At the same time, the Paris Agreement formally acknowledges the human rights implications of the unfolding climate crisis. Given the reliance on data and rights in climate change governance, the aim of this article is twofold. Firstly, it analyzes how processes of datafication at transnational and local levels promise, yet struggle, to render the climate governable. Secondly, the article critically reflects on the capacity of human rights to complement datafied governance processes meaningfully – specifically, in what ways rights can (and cannot) alleviate local concerns regarding datafication. Methodologically, the article develops a perspective that foregrounds situated sense-making and experience in place. It is based on an empirical case study of the Global Covenant of Mayors for Climate & Energy, a transnational alliance of cities that have committed to working towards the goals of the Paris Agreement; and it engages with ethnographic literature that conceptualizes rights as lived forms of meaning-making, articulation, struggle, and resistance. Attending to place, the article confronts problematic assumptions about the universality, neutrality, and representativeness of data and rights, raising critical questions about their capacity to ‘govern’ climate change.
