Media Narratives Beyond the Headlines: A Review on Global Media Coverage of the COP15 UN Biodiversity Summit

Global media narratives refer to how international news outlets frame and present stories, shaping public perception and discourse on significant events like the COP15 UN Biodiversity Summit. This includes the themes, tones, and emphases used by different media sources to convey the importance, implications, and outcomes of such global events. This study explores global media coverage and narratives during the COP15 summit in December 2022, aiming to analyze dominant themes presented by international media, identify differences in reporting approaches among major outlets, and evaluate the influence of these narratives on public awareness and policy discourse regarding biodiversity. Using content analysis, the research studies news from various outlets to identify and quantify key themes such as ecological urgency, economic implications, policy negotiations, and scientific discoveries. Comparative analysis highlights variations in coverage focus, tone, and depth, revealing how regional contexts and media ownership influence reporting styles. Findings indicate that while some media outlets prioritize policy negotiations and economic implications, others emphasize ecological urgency and scientific findings, leading to varied public and policy responses. This research underscores the critical role of media in shaping public understanding and influencing policy debates on biodiversity. By providing insights into effective reporting practices, the study aims to enhance the quality of environmental journalism and foster informed public and policy engagement with biodiversity issues, contributing to the broader discourse on environmental communication and the power of media narratives in addressing global environmental challenges.

The deglacial history of 79N glacier and the Northeast Greenland Ice Stream

The Northeast Greenland Ice Stream (NEGIS) is the main artery for ice discharge from the northeast sector of the Greenland Ice Sheet (GrIS) to the North Atlantic. Understanding the past, present and future stability of the NEGIS with respect to atmospheric and oceanic forcing is of global importance as it drains around 17% of the GrIS and has a sea-level equivalent of 1.6 m. This paper reconstructs the deglacial and Holocene history of Nioghalvfjerdsbræ (or 79N Glacier); a major outlet of the NEGIS.At high elevation (>900 m asl) autochthonous blockfield, a lack of glacially moulded bedrock and pre LGM exposure ages point to a complex exposure/burial history extending back over half a million years. However, post Marine Isotope Stage 12, enhanced glacial erosion led to fjord incision and plateaux abandonment. Between 900 and 600 m asl the terrain is largely unmodified by glacial scour but post LGM erratics indicate the advection of cold-based ice through the fjord. In contrast, below ∼600 m asl Nioghalvfjerdsfjorden exhibits a geomorphological signal indicative of a warm-based ice stream operating during the last glacial cycle. Dated ice marginal landforms and terrain along the fjord walls show initial thinning rates were slow between ∼23 and 10 ka, but post-10 ka it is evident that Nioghalvfjerdsfjorden deglaciated extremely quickly with complete fjord deglaciation below ∼500 m asl between 10.0 and 8.5 ka.Both increasing air and ocean temperatures were pivotal in driving surface lowering and submarine melt during deglaciation, but the final withdrawal of ice through Nioghalvfjerdsfjorden was facilitated by the action of marine ice sheet instability. Our estimates show that thinning and retreat rates reached a maximum of 5.29 ma−1 and 613 ma−1, respectively, as the ice margin withdrew westwards. This would place the Early Holocene disintegration of this outlet of the NEGIS at the upper bounds of contemporary thinning and retreat rates seen both in Greenland and Antarctica. Combined with recent evidence of ice stream shutdown during the Holocene, as well as predictions of changing ice flow dynamics within downstream sections of the NEGIS catchment, this suggests that significant re-organisation of the terminal zone of the ice stream is imminent over the next century.

Seawater Intrusion at the Grounding Line of Jakobshavn Isbræ, Greenland, From Terrestrial Radar Interferometry

AbstractJakobshavn Isbræ, a major outlet glacier in Greenland, lost its protective ice shelf in 2002 and has been speeding up and retreating since. We image its grounding line for the first time with a terrestrial radar interferometer deployed in 2016 and detect its migration at tidal frequencies. The southern half of the glacier develops a floating section (3 km × 3 km) that migrates in phase with the tidal difference, up to a distance of 2.8 km, far more than previously expected. We attribute the migration to kilometer‐scale seawater intrusions, 10–20 cm in height, with the tide. The intrusions reveal that the glacier bed may be up to 800 m deeper than expected on the south side, which illustrates that our knowledge of bed topography remains limited for this glacier. We expect seawater intrusions to cause rapid melt of basal ice and play a major role in the glacier evolution.

Prevalence, correlates, and reasons for substance use among adolescents aged 10–17 in Ghana: a cross-sectional convergent parallel mixed-method study

BackgroundSubstance use among adolescents poses significant risks to their health, wellbeing, and development, particularly in low- and middle-income countries, including Ghana. However, little is known about the outlets and reasons for substance use among Ghanaian adolescents. This study examined the prevalence, correlates, reasons for substance use, and outlets of these substances among adolescents aged 10–17 in Ghana.MethodsData were obtained from the Department of Children, Ministry of Gender, Children, and Social Protection, Ghana, which employed a cross-sectional convergent parallel mixed-methods technique to collect quantitative and qualitative data from children aged 8–17, parents or legal guardians and officials of state institutions responsible for the promotion and protection of children’s rights and wellbeing. Overall, 4144 adolescents aged 10–17 were interviewed for the quantitative data, while 92 adolescents participated in 10 focus group discussions. Descriptive statistics, Pearson’s chi-square test, and multivariable binary logistic regression were used to analyse the quantitative data, while the qualitative data was analysed thematically.ResultsThe prevalence of substance use was 12.3%. Regarding the types of substance use, alcohol (56.9%) and cigarettes (26.4%) were the most common substances. Being a male and currently working are significant risk factors, whereas being aged 10–13, and residing in the Middle- and Northern-ecological belts of Ghana are significant protective factors of substance use. Peers, household members who use substances, drug stores, and drug peddlers are the major outlets. The reasons for substance use were fun, substance as an aphrodisiac, boosting self-confidence, dealing with anxiety, and improved social status.ConclusionsThere is a relatively high substance use among adolescents in Ghana, and this calls for a multi-sectoral approach to addressing substance use by providing risk-behaviour counselling, parental control, and effective implementation of substance use laws and regulations.

An Op-Ed Writing Curriculum for Medical Students to Engage in Advocacy Through Public Writing.

Op-ed writing can be a powerful and accessible advocacy tool for physicians, but training is lacking in undergraduate medical education. To train and engage first-year medical students in op-ed writing. Midwestern research-intensive medical school. All students in a required first-year health policy course in 2021 and 2022. For their health policy course's final assignment, students could opt to write an op-ed on a healthcare issue of their choice. All students received written instruction on op-ed writing. Additionally, they could access a seminar, coaching and editing by peers and faculty, and publication guidance. Of 179 students over 2years, 105 chose to write op-eds. Fifty-one attended the seminar, 35 attended peer coaching sessions, 33 accessed structured peer editing, and 23 received faculty assistance. Thirty-eight students submitted a total of 42 op-eds for publication. Twenty-two pieces were published in major outlets and 17 in the university's health policy review. Of the 22 in major outlets, 21 received editing from either peers or faculty. An op-ed writing curriculum can be integrated into an existing medical school health policy course, resulting in a high level of engagement and in published op-eds by medical students.

Jewish Women and the Making of the Levant Fair in the Interwar Era

ABSTRACT This study investigates the contribution of Jewish women to the Levant Fair during the interwar period. In its time, the Fair became one of the major outlets that permitted Jewish women to contribute to nation-building in the pre-state period, mainly due to a dearth of otherwise suitable opportunities for women. Women participation, however, neither transformed power relations between men and women, nor expanded economic and social rights available to women at the time.

Water sources of the Lombok, Ombai and Timor outflows of the Indonesian throughflow

The Lombok Strait (LS), Ombai Strait (OS), and Timor Passage (TP) are three major outlets of the Indonesian Throughflow to the Indian Ocean. Here, sources and pathways of the LS, OS, and TP outflows are explored by a Lagrangian particle tracking analysis based on a ~3 km regional ocean model simulation. The Makassar Strait transport contributes to ~80%, ~75%, and ~45% of the LS, OS, and TP outflows, respectively. However, ~41% and ~19% of the TP and OS outflows stem from the Lifamatola Passage, which largely feeds the upper and intermediate layers of the outflows. The role of Karimata Strait is quite limited and restricted to the upper layer. It takes 1-2 years and 2-6 years for the Makassar Strait water to reach the OS and TP, respectively, whereas the Lifamatola Passage water passes through the OS (2-6 years) and TP (3-9 years) on a prolonged transit time. In the Banda Sea, the western boundary current is the main pathway toward the OS, while the waters to the TP tend to take a basin interior route.

INDOMARET VS ALFAMART : THE BATTLE FOR STORE ATMOSPHERE SUPREMACY

Indomaret and Alfamart, two retail giants in Indonesia, compete fiercely for market share. This study focuses on the Competition in the in-store experience, known as "store atmosphere." Store atmosphere is a key factor in the retail business that can influence customer behavior and satisfaction" Store atmosphere is a key factor in the retail business that can influence customer behavior and satisfaction. This study aims to understand the comparison of consumers' assessment of store atmosphere in the two major outlets. A total of 384 respondents provided ratings for 13 store atmosphere attributes, and the results were analyzed using the Importance Performance Analysis (IPA) method. The results showed that both Indomaret and Alfamart have similar challenges in creating a satisfying store atmosphere for customers. Some attributes such as store layout, display, exterior, and interior have performance that is rated low by customers. Both companies need to take corrective actions to meet customer expectations for these attributes. Both companies should understand their customers' preferences and focus on attributes that have a higher priority in creating a satisfying store atmosphere, while maintaining good quality performance on attributes that are already adequate. In conclusion, competition between Indomaret and Alfamart remains fierce, with store atmosphere being an Importance factor in winning over customers.

Estimation of the riverine input of organic ultraviolet filters (OUVFs) from the Pearl River Estuary to the South China Sea during the early Covid-19 pandemic

Organic ultraviolet filters (OUVFs) are functional ingredients used in cosmetics to protect skin from the harmful effects of ultraviolet (UV) radiation. This study presents recent findings on the distribution of OUVFs in the Pearl River Estuary (PRE), located in southern China. This investigation was conducted during the early stages of the Covid-19 pandemic when the stay-at-home policy was implemented. Analysis revealed the presence of OUVFs in both the surface and bottom water samples collected from eight major outlets of the Pearl River. The OUVFs were detected in both the dissolved phase and suspended particulate matter, with a total concentration ranging from 7.19 ± 6.54 to 20.5 ± 9.62 ng/L. Notably, OUVFs' concentrations in the study period were significantly lower compared to those reported before the pandemic. This implies that effective reduction of OUVF emissions can be achieved through usage reduction combined with the management of direct discharge and appropriate treatment by urban wastewater treatment facilities. During the study period, the annual release of OUVFs was approximately 12.6 kg/1000 people/year, with the greatest contribution from the Hu Men outlet. Consequently, it is imperative to consider the potential ecological risks associated with the release of OUVFs from the PRE into the marine environment, particularly with the potential for an accompanying rebound in risk upon the lifting of restrictions on outdoor activities in the post Covid-19 time.

Extensive and anomalous grounding line retreat at Vanderford Glacier, Vincennes Bay, Wilkes Land, East Antarctica

Abstract. Wilkes Land, East Antarctica, has been losing mass at an accelerating rate over recent decades in response to enhanced oceanic forcing. Overlying the Aurora Subglacial Basin, it has been referred to as the “weak underbelly” of the East Antarctic Ice Sheet and is drained by several major outlet glaciers. Despite their potential importance, few of these glaciers have been studied in detail. This includes the six outlet glaciers which drain into Vincennes Bay, a region recently discovered to have the warmest intrusions of modified Circumpolar Deep Water (mCDW) ever recorded in East Antarctica. Here, we use satellite imagery; differential synthetic aperture radar interferometry (DInSAR); and remotely sensed datasets of ice-surface velocity, ice-surface elevation and grounding line position to investigate ice dynamics between 1963 and 2022. Our results support previous observations of extensive grounding line retreat at Vanderford Glacier, measured at 18.6 km between 1996 and 2020. The persistent grounding line retreat, averaging 0.8 km yr−1, places Vanderford Glacier as the fastest retreating glacier in East Antarctica, and the third fastest in Antarctica, across decadal timescales. Such rapid retreat is consistent with the hypothesis that warm mCDW is able to access deep cavities formed below the Vanderford Ice Shelf, driving high rates of basal melting close to the grounding line. With a retrograde slope observed inland along the Vanderford Trench, such oceanic forcing may have significant implications for the future stability of Vanderford Glacier.

A steady-state model reconstruction of the patagonian ice sheet during the last glacial maximum

During the Last Glacial Maximum (LGM), the Patagonian Ice Sheet (PIS) was the largest Quaternary ice mass in the Southern Hemisphere outside of Antarctica. Although the margins of the LGM ice sheet are now well established through end-moraine mapping and dating, apart from a few modelling and empirical studies, there remains a lack of constraint on its thickness and three-dimensional configuration. Here, we provide a high-resolution steady-state model reconstruction of the PIS at its maximum - LGM - extent applied using Nye's perfect-plastic ice rheology. The yield-strength parameter for the perfect-plastic flow model was calibrated against independent empirical reconstructions of the Lago Pueyrredón Glacier, where the former vertical extent of this major outlet glacier is well constrained by cosmogenically-dated trimlines and lateral and end-moraine limits. Using this derived yield-strength parameter, the perfect-plastic model is then applied to multiple flowlines demarking each outlet across the entirety of the PIS in a GIS framework. Our results reveal that the area of the PIS was ∼504,500 km2 (±8.5%) with a corresponding modelled ice volume of ∼554,500 km3 (±10%), equivalent to ∼1.38 m (±10%) of eustatic sea-level lowering at the LGM. Maximum surface elevation was at least 3500m asl although the majority of the ice sheet surface was below 2500 m asl. We find that our ice sheet reconstruction is in good general agreement with previous estimates of net PIS volume derived from transient modelling studies. We attribute the slightly lower aspect-ratio of our ice sheet (and its concomitant 5% reduction in volume and sea-level equivalent) to the lower yield strength applied, based on more temperate and dynamic ice sheet conditions.

Post-Civil War Literary Fiction: A Catalyst for Understanding Sierra Leone's Recent Past, Present, and Future

ABSTRACT: Until very recently, it seemed that a major difference between the literature of Sierra Leone and the literatures of its other West African neighbors was the absence, especially in prose fiction, of a sustained body of work by Sierra Leonean authors. This situation might seem mystifying to scholars of Sierra Leone's social and intellectual history because, after all, that country had played a major and pioneering role in the development and spreading of Western education in West Africa. This fundamental narrative of the inability of Sierra Leone's creative writers to produce high quality literature, in current times, has been seriously challenged by several new authors. This article analyzes the ways in which Sierra Leonean literature has moved from a space in which its earliest writers failed to understand fiction writing as a major outlet to express the dreams, nightmares, hopes and desires of a people to one in which high quality fiction is flourishing. It highlights how the civil war and its dreadful aftermath changed the literary landscape in Sierra Leone in many positive ways.

Broadening the lens on bisphenols in coastal waters: Occurrence, partitioning, and input fluxes of multiple novel bisphenol S derivatives along with BPA and BPA analogues in the Pearl River Delta, China

Bisphenol S derivatives (BDs) are being widely used as novel substitutes for BPA and BPA analogues (BPAs), causing pollution in various environmental compartments. However, the occurrence and fate of BDs in coastal waters are currently unknown. To broaden the lens on bisphenols in coastal waters, this study measured a broad suite of 23 bisphenols, including 12 BDs along with BPA and 10 BPAs, in water, suspended particulate matter (SPM), and sediment from eight major outlets of the Pearl River Delta, China (PRD). In addition to BPA and BPAs, all the 12 BDs were detected in the collected samples. The total concentration of 12 BDs ranged from 1.2 to 25 ng/L (median of 4.3 ng/L) in water samples, 0.80–13 ng/g dw (median of 3.0 ng/g dw) in SPM samples and 0.48–3.7 ng/g dw (median of 0.64 ng/g dw) in sediment samples. For most individual BDs, they had comparable concentrations to individual BPAs. In addition, logKd values of the frequently detected bisphenols, including BPA, BPS, BPF, 4-((4-Isopropoxyphenyl)sulfonyl)phenol (BPSIP), 2,4-bis(phenylsulfonyl)phenol (DBSP), and other 9 bisphenols, were significantly correlated with their logKow values (R2 = 0.38, p < 0.05), indicating that the partitioning of bisphenols between the aqueous and SPM phases were strongly influenced by hydrophobic interaction. Based on bisphenols’ concentrations in water from the eight outlets of PRD, the estimated input fluxes of novel BDs (1900 kg/y) were found to be even higher than that of BPAs (550 kg/y). This indicates that the riverine input of BDs into the coastal environment is gradually increasing, which should be taken seriously in the future.

Seasonal Acceleration of Petermann Glacier, Greenland, From Changes in Subglacial Hydrology

AbstractPetermann Glacier is a major outlet glacier of northern Greenland that drains a marine‐based basin vulnerable to destabilization from enhanced oceanic and atmospheric forcings. Using satellite radar interferometry data from the Sentinel‐1a/b missions, we observe a seasonal glacier acceleration of 15% in the summer, from 1,250 to 1,500 m/yr near the grounding line, but the physical drivers of this seasonality have not been elucidated. Here, we use a subglacial hydrology model coupled one‐way to an ice sheet model to evaluate the role of subglacial hydrology as a physical mechanism explaining the seasonal acceleration. We find excellent agreement between the observed and predicted velocity in terms of timing and magnitude with the addition of an applied lower limit on effective pressure of 6% of ice overburden pressure. We conclude that seasonal changes in subglacial hydrology are sufficient to explain the observed seasonal speed up of Petermann Glacier.

Modelowanie pandemii w narracjach spekulatywnych: «„Andromeda” znaczy śmierć» (1969) Michaela Crichtona i „The Andromeda Evolution” (2019) Daniela H. Wilsona

Covid-19 pandemic has brought public attention to digital methods of modeling contagion, which have been used not only to predict the future of the infection, but also assess its scope of impact on population and the chances for achieving herd immunity. As a result new outbreak narratives come into being in which algorithmic data processing gains agency in shaping the dynamics of contagion. His unprecedented reliance on modeling tools has decidedly changed the way we think about epidemic, conceptualized now as a phenomenon which to an equal extent is shaped by natural, cultural and technological factors. He paper argues that the major outlet for these new metaphors of contagion, which Milton Singer termed syndemic, are speculative narratives combining fiction with scientific and medical data as well as insights into the functioning of the digital modeling apparatus. His aspect of the current pandemic provides a good vantage point for taking a closer look at a handful of speculative narratives which bring to the foreground the relationship between modeling and social impact of contagion. By reading Michael Crichton’s technothriller The Andromeda Strain (1969) and its sequel, Daniel H. Wilson’s The Andromeda Evolution (2019), I intend to demonstrate how speculative fabulations engages and contests methods of contagion modeling, bringing into play other forms of non-scientiIc knowledge and practices of survival.

Modelled dynamic retreat of Kangerlussuaq Glacier, East Greenland, strongly influenced by the consecutive absence of an ice mélange in Kangerlussuaq Fjord

AbstractMass loss at the Greenland Ice Sheet is influenced by atmospheric processes controlling its surface mass balance, and by submarine melt and calving where glaciers terminate in fjords. There, an ice mélange – a composite matrix of calved ice bergs and sea ice – may provide a buttressing force on a glacier terminus and control terminus dynamics. Kangerlussuaq Glacier is a major outlet of the Greenland Ice Sheet, for which recent major retreat events in 2004/2005 and 2016–2018 coincided with the absence of an ice mélange in Kangerlussuaq Fjord. To better understand the response of Kangerlussuaq Glacier to climatic and oceanic drivers, a 2D flowline model is employed. Results indicate that an ice mélange buttressing force exerts a major control on calving frequency and rapid retreat. When an ice mélange forms in Kangerlussuaq Fjord, it provides stabilising forces and conditions favourable for winter terminus re-advance. When it fails to form during consecutive years, model results indicate that Kangerlussuaq Glacier is primed to retreat into the large overdeepenings in Kangerlussuaq Fjord, and to terminus positions more than 30 km farther inland, implying that excessive mass loss from Kangerlussuaq Glacier by the year 2065 cannot be excluded.

The domestication of “the Arab Spring”: A comparison of news framing in the United States and South Korea

By employing a content analysis of news stories, this study explored how national history, national interests and journalistic values have affected the coverage of the Arab Spring by South Korea and the United States. Overall, the lens of national interest largely determined the newsworthiness of stories in the two nations. Journalists’ perspectives on journalism (specifically, on the role of journalists) as well as media routines have also influenced journalists’ presentations of the Arab Spring. The U.S. newspaper coverage relied on the views of Arab opposition figures and civilians most prominently, followed by those of U.S. government officials; while the South Korean papers relied heavily on foreign media as their sources (in particular, Western media). While this difference in news sourcing led to correspondingly divergent news frames, ironically, it often also resulted in a congruence between the news frames employed in each country’s major news outlets. This study proposes that national interests and history should be further considered as important dimensions for developing the models of media systems.

A reconstruction of Jostedalsbreen during the Little Ice Age and geometric changes to outlet glaciers since then

Mountain glaciers and ice caps are undergoing rapid mass loss but rates of present-day changes and models of future projections both lack long-term (centennial-scale) context. Here, we reconstruct the maximum glacier extent and ice surface of Jostedalsbreen, which is the largest ice mass in mainland Europe, during the Little Ice Age (LIA) ∼ 1740 to 1860. The LIA maximum ice-covered area was 568 km2 and the LIA ice volume was between 61 km3 and 91 km3. We show that the major outlet glaciers have lost at least 110 km2 or 19% of their LIA area and 14 km3 or 18% of their LIA volume until 2006. The largest proportional changes for individual outlet glaciers are associated with the loss of ice falls and consequent disconnection of tributaries. Glacier-specific hypsometry changes suggest a mean rise in ELA of 135 m but there is wide inter-glacier variability. A median date for the LIA of 1755 suggests that the long-term rate of ice mass loss has been 0.05 m w.e. a−1. That long-term rate is virtually the same as modern rates, which contrasts with findings of other studies around the world reporting acceleration of glacier mass loss rates since the LIA. Overall, we highlight the utility of geomorphological-based reconstructions of glaciers for understanding and quantifying long-term (centennial-scale) responses to climate and hence for understanding of meltwater production and proglacial landscape evolution.
