Mangiferin is a xanthonoid found in Mango leaves in abundance with many effects as a hypoglycemic, antioxidant, and anti-inflammatory agent, plant metabolite, and so on. However, nowadays, mango leaves are merely a waste product in Vietnam. To take advantage of this valuable medicinal resource, extraction conditions of mangiferin using classical and ultrasound methods were researched, and mangiferin was purified from Cat Chu mango leaves (Mangifera indica L., Anacardiaceae) collected in Dong Thap. Ultrasound-assisted extraction method was conducted with the following conditions and mangiferin was extracted at a percentage of 6.728% with a purity of 91.11%. Purified mangiferin was evaluated using molecular absorption spectroscopy UV-Vis, scanning electron microscopy (SEM), X-ray diffraction (XRD) spectroscopy, simultaneous thermal analysis (STA: TGA/DSC), and dissolution measurement method. To optimize the solubility and permeability of mangiferin, the solid dispersion system (HPTR) was made by the combination of HPMC 6M:mangiferin at the ratio of 1:5. To investigate the acute, sub-chronic toxicity and hypolipidemia effect of HPTR as compared to purified mangiferin, we followed guidelines for preclinical and clinical trials of Traditional Medicine and Herbal Medicines by the Vietnam Ministry of Health and OECD, and used tyloxapol (Triton WR1339, 400 mg/kg, i.p.) to induce hyperlipidemia. Our results indicated that purified mangiferin and HPTR extract showed no acute toxicity and sub-chronic toxicity and has potential as an antihyperlipidemic agent. The HPTR brought about a significant decrease in total cholesterol, triglycerides and LDL-c when compared to mangiferin, however there was no significance between them.

Objective

Although previous studies have explored the association of drinking with gout risk, we sought to explore the dose-response relationship and the evidence between subtypes of alcoholic beverages and gout risk.

Methods

The weekly alcoholic beverage consumption of patients in the UK Biobank was collected and calculated. The Cox regression model was applied to assess the effects of drinking alcohol in general and its subtypes on gout risk by calculating the hazard ratio (HR) and 95% CIs. Additionally, the restricted cubic splines were used to estimate the dose-response relationship between alcohol consumption and gout risk. To evaluate the robustness, we performed subgroup analysis across various demographic characteristics.

Results

During a mean follow-up period of 11.7 years, a total of 5728 new incident gout cases were diagnosed among 331,865 participants. We found that light alcohol consumption was linked to a slight decrease in gout incidence among female individuals (HR 0.78, 95% CI 0.65-0.94,P= 0.01), whereas there was no significant association in male individuals. Moreover, the dose-response relationship showed that drinking light red wine and fortified wine could reduce the gout risk, whereas beer or cider, champagne or white wine, and spirits increased the gout risk at any dose.

Conclusion

Our study suggested a J-shaped dose-response relationship between drinking and gout risk in female individuals, but not in male individuals. For specific alcoholic beverages, light consumption of red wine and fortified wine was associated with reduced gout risk. These findings offer new insights into the roles of alcoholic beverages in gout incidence risk, although further validation is warranted.

Published: May 2024

The infection caused by Rift Valley fever (RVF) virus is a dangerous vector-borne disease found in humans, domestic, and wild animals. It is transferred through insect vectors to ruminant host and then spread through direct contact of infected animals with their body fluid or organs. In this paper, a fractal-fractional model for the transmission of RVF in the Caputo's sense was presented. We analyzed the model and determined the basic reproduction number through the next-generation matrix technique, indicated by $ \mathcal{R}_0 $. The global sensitivity technique is used for the sensitivity test of $ \mathcal{R}_0 $ to find out the most sensitive input-factors to the reproduction parameter $ \mathcal{R}_0 $. The existence and uniqueness results of the proposed fractal-fractional model were established. Then, we presented the fractal-fractional dynamics of the proposed RVF model through a novel numerical scheme under the fractal-fractional Caputo operator. In the end, the recommended model of RVF was highlighted numerically with the variation of different input parameters of the system. The key factors of the system were highlighted to the policymakers for the control and prevention of the infection.
A SENSITIVITY ANALYSIS METHOD COMBINING DEMPSTER-SHAFER THEORY AND MACHINE LEARNING FOR ENERGY-SAVING EVALUATION OF BUILDING OCCUPANT BEHAVIOR
Authors: Xuanyuan Peisong , Yao Jian , Knefaty Ala Deen , Laurice Sossou Espoir
Published: May 2024

For a very long time, the research of the sensitivity analysis of occupant behavior to energy assessment has been in the spotlight. The key element of the research is determining the exact probability of occupant behavior uncertainty. However, due to the specificity of occupant behavior, data on occupant behavior from different independent sources of information can differ significantly. This paper explores the use of Dempster-Shafer theory to the sensitivity analysis of energy evaluation of occupant behavior in buildings. The Dempster-Shafer theory is an imprecise probability theory that allows the system to create assumed confidence intervals based on interval values probability combined with knowledge of uncertainty factors from many different sources of information. The findings show that the data processing approach based on Dempster-Shafer theory provides effective and reliable information for evaluating energy related to human behavior in buildings. To begin with, the sensitivity analysis process might be accelerated by applying machine learning to process the data. Then, in order to ensure the accuracy of the simulation results, multiple learning methods can be used. Finally, in this paper, model parameters were chosen based on the specific circumstances as soon as the model had been built in order to effectively reduce costs related to operation and increase model accuracy. To establish the final results, the model is evaluated using global sensitivity analysis methods.
L’éducation au développement durable : entre internationalisation et effets locaux. Introduction
Authors: Barthes Angela , Lange Jean-Marc
Published: May 2024

Les prescriptions éducatives locales incitent à prendre en charge les problèmes sociétaux globaux et évoluent en fonction des préconisations politiques internationales. Dans ce jeu d’influences réciproques, les curriculums, les finalités et les valeurs de l’éducation au développement durable diffèrent selon le positionnement géopolitique des pays, et ce, en interférence avec les crises politiques, sociales et environnementales locales. Devant les urgences climatiques et l’érosion de la biodiversité, on relève dans de nombreux pays une demande sociale de justice et un souhait de transformer les modèles de développement qui interpellent de façon critique la conception et la mise en œuvre de l’éducation au développement durable dans les systèmes d’enseignement. Ce dossier à visée comparatiste présente neuf études de cas révélatrices du décalage, ou tout au moins de la tension qui existe entre contextes locaux et injonctions internationales, et met en évidence des dispositifs et des pratiques spécifiques sur quatre continents.
L’éducation au développement durable au prisme de la religion : le cas iranien
Authors: Paivandi Saeed
Published: May 2024

Le curriculum iranien a connu un tournant écologique progressif depuis les années 2000. Les thématiques environnementales se sont introduites dans le manuel d’études sociales et celui de sciences expérimentales. Au 11e grade, tous les élèves suivent une matière intitulée « humain et environnement ». Le texte propose une grille d’analyse thématique des contenus écologiques dans les manuels de 2023-2024. Dans un pays confronté à une crise écologique aiguë, les données collectées permettent de constater la vision assez réductrice du discours environnemental de l’école iranienne. Le curriculum tente de promouvoir une sorte d’éco-civisme en mettant l’accent sur la responsabilité individuelle. Il s’agit de se focaliser sur la gestion technique de l’environnement et l’éco-efficience en écartant les questions sociales et économiques. Cette orientation curriculaire doit être appréhendée et analysée dans le contexte d’un système éducatif « islamisé », imposant un endoctrinement religieux aux élèves.
L’éducation au développement durable dans une société progressiste pétro-dépendante : le cas de la Norvège
Authors: Wagner David-Alexandre
Published: May 2024

Le cas de l’éducation au développement durable (EDD) en Norvège est intéressant, car le pays souhaite être à la pointe en matière environnementale, tout en étant un important producteur d’hydrocarbures. De fait, l’EDD a été intégrée en profondeur à tous les niveaux du curriculum et promue thématique transversale commune à toutes les matières enseignées. L’ambition est de développer chez les élèves tant une compréhension profonde des enjeux environnementaux que des compétences pratiques pour agir. Cependant, la grande part de liberté et de responsabilité laissée aux enseignants ainsi que le fort accent porté sur la responsabilité individuelle de chacun et sur les enjeux environnementaux et sociaux, plutôt qu’économiques, semblent aussi porteurs de défis, présents et à venir.
Between Empires: Women’s Resistance and Domestic Slavery in the Libyan Territories in the Nineteenth and Twentieth Centuries
Authors: Yeaw Katrina
Published: May 2024

In 1854, Fekiriyeh and Renghi Sefa, two enslaved girls from the Sudan, fled their enslaver, Ahmed Pasha, and sought refuge in the house of the British Consul in Salonica. Their ordeal had begun weeks earlier when they were loaded onto a ship and transported from the Ottoman Tripoli to the Greek port city. To evade the Ottoman prohibition on slave trafficking within the Empire, the Pasha furnished them with manumission papers. On arrival in Salonica, the Pasha confiscated the documents and destroyed them. After Ahmed Pasha revoked their freedom, the two girls absconded, showing up at the door of the British Consul.This article examines historical cases of enslaved women and girls, like Fekiriyeh and Renghi Sefa, who escaped their enslavers and sought refuge or help from various political authorities in Ottoman and post-Ottoman Libya or connected territories. These cases were often marked by trafficking, enslavement, abuse, sale, and an eventual quest for emancipation, By analyzing the interactions between enslaved individuals, European and Ottoman authorities, and Muslim households, this study highlights the gendered nature of slavery in North Africa.Contrary to conventional top-down perspectives, this research emphasizes the importance of the individual actions of enslaved women in seeking alternative authorities, such as foreign consulates, to adjudicate their claims. Despite opposition to the trans-Saharan slave trade and the slave trade within the Ottoman Empire before its disintegration after the First World War, British representatives avoided getting involved in cases of domestic slavery in Libya. Italian authorities would continue a similar policy after annexing the territory in 1911. Notwithstanding this reluctance, enslaved girls and women learned through various networks how to find sympathetic forums for their grievances. Evaluating the policies of British Consuls, Italian abolitionists, and the Italian colonial government, this paper argues that the actions of enslaved women, rather than male policymakers, were central to changing the status of enslaved individuals and eventually contributing to abolition.The focus on the experiences of girls like Fekiriyeh and Renghi Sefa exemplifies the importance of documenting enslaved girls' and women's lives and experiences. While the ultimate fate of these women and girls post-manumission remains unknown, their courageous efforts to resist enslavement contribute to a broader understanding of the intricacies of abolition in Libya and the larger Ottoman World in the nineteenth and twentieth centuries.
Laboring Under an Illusion: Erasing Female Public Labor in Post-Abolition Zanzibar Islands, 1890–1910
Authors: McMahon Elisabeth
Published: May 2024

Female workers were central to the coastal East African labor force during the 19th and early 20th centuries, yet their bodies have disappeared from the historical narratives of public and skilled labor. Colonial officials wrote copiously about African labor along the Swahili coast; how to find laborers, how to coerce them into working, the categories of labor, what skills laborers held, how much they should be paid, how to efficiently move them to where they were needed, among many other aspects. However, these same officials, when writing about female laborers, often eliminated mention of females from both the skilled workforce and from their status as an equal portion of free laborers in the post-abolition era. Women and girls in the nineteenth century were present in the public labor force throughout littoral communities, yet reading the records of colonial officials and historians would suggest otherwise. This epistemic erasure has warped the way historians have thought and written about labor across coastal eastern Africa. Colonial officials gendered almost all forms of public, and particularly skilled labor, as male – for both enslaved and freed workers – an erasure often mimicked in the work of historians, thus reifying colonial views of an idealized labor force that was dominated by skilled male laborers with a few low-skill female manual workers.The British belief in the “benevolence” of Arab slave-owners was a longstanding one, a belief that officials in the Zanzibar Islands used to justify their slow response to the metropole demand for the abolition of slavery. The “benignity concept” as Marek Pawelczak termed it was so pervasive in colonial reports that historians into the 21st century still use it as an argument for why slavery in the Zanzibar islands was “mild” and required “not more than twelve hours’ labour” in any given week. Hidden within the “benignity concept” is an image of enslavement as wholly domestic, and therefore implicitly feminized. What is more insidious about the benignity concept is that British officials used it in the late 1890s both to justify allowing slavery to continue and figuratively to erase female enslaved laborers as workers, rather making them “domestics” and as such part of the household. Beginning in 1895, descriptions of an enslaved female became either one of a luxuriously kept concubine who was in essence a “secondary wife” or simply of a wife and mother. Men were enslaved, women were wives, and children were no longer part of the conversation at all. Similarly, I argue here that referring to laborers as ungendered historical actors obliterates significant pieces of history and distorts our understanding of the past. The distortions in colonial record-keeping has perpetuated an epistemic erasure in contemporary literature on labor in eastern Africa, which is an act of epistemic violence.

Pour une prise en compte géographique de la commande publique dans l’analyse des dynamiques d’innovation territoriale
Authors: David Pascal
Published: May 2024

La commande publique constitue, en géographie et en aménagement, un objet peu considéré par la communauté scientifique française et internationale. Ce constat est à mettre en relation avec l’abondante littérature scientifique provenant d’autres disciplines connexes (droit, économie, sciences de gestion). En France, aucune thèse portant sur le sujet n’a jamais été soutenue, peu ou pas d’articles ou de livres ont été publiés sur cette rencontre entre « la commande publique » et « les territoires ». Ce constat interroge alors même que la commande publique participe directement à la mise en œuvre des politiques publiques. Ce travail de recherche s'intéresse précisément à sa prise en compte dans l’analyse des dynamiques d’innovation territoriale. A la croisée de la science régionale, de la géographie et de la recherche en aménagement du territoire, il vise à enrichir la compréhension des processus d’intermédiation en analysant comment, à l'échelle des territoires, la commande publique permet la coordination et l'appariement entre des acteurs aux temporalités différentes et aux objectifs divergents. La perspective de la ville intelligente et durable est introduite comme cadre d'analyse pertinent pour étudier la fabrique de l’innovation urbaine. Le texte décrit une méthodologie de recherche axée sur l'étude de cas de la scène toulousaine engagée depuis 2014 dans des programmes de soutien à l’innovation, le protocole intégrant une revue de littérature, une analyse systémique, la collecte de données via des entretiens semi-directifs, une approche comparative avec d’autres scènes territoriales similaires.

Internet of Things Framework for Sustainable Agriculture in Smart Farming
Authors: Bais Pratima , Bahadur Preeti Singh
Published: May 2024

The global human population is constantly increasing whereas the agricultural land resources are declining for reasons of urban settlements and industrial growth. This has certainly strained the agricultural sector for increased annual yields, especially in the changing climate. To accomplish the rising demand of consumers for food, feed, and fiber, up to 70% upsurge in crop production is farsighted by 2050. The agricultural industry is getting more data-centric and requires precise, more advanced data and technologies than before, despite being familiar with agricultural processes. The agriculture industry is being advanced by various information and advanced communication technologies, such as the internet of things (IoT) and cloud computing are anticipated to inspire growth and initiate the use of robots and artificial intelligence in farming. The rapid emergence of these advanced technologies has restructured almost all other industries, as well as advanced agriculture, which has shifted the industry from a statistical approach to a quantitative one.

Grid computing, utilizing distributed resources, achieves goals in handling workloads in a distributed system. Unlike traditional high-performance computing, grid computing assigns tasks to nodes, showcasing heterogeneity without physical coupling. Grids, with variable sizes based on applications, use general-purpose middleware. In modern energy systems, integrating smart grids and grid computation is vital. Emphasizing resource efficiency, grid computation enhances smart grid performance; by enabling real-time monitoring, rapid adjustments for optimization, and outage prevention. Grid computation supports demand response strategies for electricity management and integrates distributed generation resources, such as solar panels and wind turbines, including autonomous microgrid supervision.
Post-genomic analysis of Monosporascus cannonballus and Macrophomina phaseolina - potential target selection
Authors: Silva Fabiana Rodrigues da , Martins Natália Florêncio , Viana Marcos José Andrade , Sales Júnior Rui , Aragão Fernando Antonio Souza de
Published: May 2024

Monosporascus cannonballus Pollack & Uecker and Macrophomina phaseolina Tassi (Goid) are phytopathogenic fungi responsible for causing "root rot and vine decline" in melon (Cucumis melo L.). Currently, cultural management practices are predominantly employed to control these pathogens, as the use of pesticides not only has detrimental environmental impacts but has also proven ineffective against them. These fungi have already undergone molecular characterization, and their genomes are now available, enabling the targeted search for protein targets. Therefore, this study aimed to identify novel target proteins that can serve as a foundation for the development of fungicides for effectively managing these pathogens. The genomes of M. cannonballus (assembly ASM415492v1) and M. phaseolina (assembly ASM2087553v1) were subjected to comprehensive analysis, filtration, and comparison. The proteomes of both fungi were clustered based on functional criteria, including putative and hypothetical functions, cell localization, and function-structure relationships. The selection process for homologs in the fungal genomes included a structural search. In the case of M. cannonballus, a total of 17,518 proteins were re-annotated, and among them, 13 candidate targets were identified. As for M. phaseolina, 30,226 initial proteins were analyzed, leading to the identification of 10 potential target proteins. This study thus provides new insights into the molecular functions of these potential targets, with the further validation of inhibitors through experimental methods holding promise for expanding our knowledge in this area.

Published: May 2024

Agroforestry systems may show low CO2 efflux, and CO2 efflux contributes to sustainability. This work aimed to evaluate the soil CO2 efflux in coffee plantations cultivated in agroforestry and full-sun systems during the winter in high-altitude tropical climate regions. The work was carried out at three family farms (RO, GI, and PA) in Minas Gerais, Brazil. Two treatments were established: coffee with and without trees, and 20 sampling spots for soil and gases. The air and soil temperatures in the agroforestry systems were lower than in the full-sun systems. The soil moisture content in agroforestry systems was higher than full-sun only on the GI. Except for the agroforestry systems in PA, all the other systems showed an increase in CO2 efflux with increasing soil moisture. This increase was more pronounced in agroforestry systems (RO), followed by full sun (RO). On the GI farm, this correlation was lower in the agroforestry system. Soil CO2 efflux was positively correlated with soil temperature and negatively correlated with total nitrogen, labile carbon and total organic carbon. Therefore, despite the microclimate stability promoted by the agroforestry systems in the winter, no decrease in the soil CO2 efflux was observed when compared to full sun systems.

Published: May 2024

Traditional heat treatments in the dairy industry are known for their high water and energy consumption, and more economically and environmentally friendly solutions are being sought. Infrared (IR) technology offers advantages in energy efficiency and environmental sustainability; however, its effectiveness in milk processing, particularly in pathogen inactivation, remains relatively unexplored. In this study, homogenized raw milk was subjected to IR treatment, and its impact on Listeria monocytogenes, Salmonella spp., and Enterobacteriaceae was assessed. Results indicate that the IR treatment effectively reduces the microbial load, achieving levels of inactivation comparable to conventional pasteurization methods (around 6 Log10 CFU/mL). Moreover, the treatment maintains milk pH levels, suggesting minimal alteration to its composition. Further research is needed to explore the full extent of IR treatment on milk sanitation efficacy, deeply exploring IR technology to fully assess its applicability and integration into dairy processing practices. Despite regulatory challenges, the Wir System Milk shows promise as a cost-effective and eco-friendly alternative for raw milk treatment.
Categoricity and multidimensional diagrams

We study multidimensional diagrams in independent amalgamation in the framework of abstract elementary classes (AECs). We use them to prove the eventual categoricity conjecture for AECs, assuming a large cardinal axiom. More precisely, we show assuming the existence of a proper class of strongly compact cardinals that an AEC which has a single model of
some
high enough cardinality will have a single model in
any
high enough cardinal. Assuming a weak version of the generalized continuum hypothesis, we also establish the eventual categoricity conjecture for AECs with amalgamation.

Кинетическое состояние и возникновение марковской динамики в точно решаемых моделях открытых квантовых систем
Authors: Trushechkin Anton Sergeevich
Published: May 2024

Обычно в теории открытых квантовых систем исследуется динамика приведенного состояния (оператора плотности) системы. Однако на ранних стадиях эволюции нельзя отделить динамику резервуара от динамики системы. С этим связано нарушение положительности решений некоторых квантовых кинетических уравнений для приведенного оператора плотности. В данной работе исследуется совместная динамика системы и резервуара на ранней стадии эволюции и предрелаксация совместного состояния к так называемому кинетическому состоянию. Кинетическое состояние системы и резервуара характеризуется тем, что оно полностью определяется приведенным оператором плотности только системы. Лишь после формирования кинетического состояния становится возможным описание эволюции приведенного оператора плотности системы в терминах полугруппы.

The Green Hydrogen Standard and the Green Hydrogen Contracting Project for People and Planet: a short overview of the current standardization process
Authors: Weiler Sibylle , Jeske Luiza
Published: May 2024

The current energy crisis as well as the urgent need to realize national and international targets to decarbonize our economy has placed green hydrogen at the centre of national strategies, government incentives and industry commitments. The Green Hydrogen Organisation (GH2), a non-profit organization, launched the ‘Green Hydrogen Standard’ and the ‘Green Hydrogen Contracting for People and Planet’. These two projects aim to provide principles and contribute to set up the regulatory framework needed to accelerate the use of green hydrogen worldwide. In addition to the standardization, accreditation and certification project, GH2 is working with the support of governments, law firms, companies and civil society groups to develop a Guide for ‘Good Green Hydrogen Contracting Standards’. This overview is intended to reflect the current standardization process presented in the preliminary Guide. Although the process is still ongoing and it might not answer every question, it is an important step to grant standards and principles needed to enable progress towards a green hydrogen economy.
Beyond Translation: Retelling and Literary History
Authors: Bhattacharya Nilanjana
Published: May 2024

“Translation” as a literary term, originated in a specific European context. However, the term has been generalised to such an extent that it is often used to read texts across languages and cultures. While this process can help in identifying and establishing links between languages and cultures, acknowledging the theoretical tools provided within the concerned literary tradition could provide better insights into the literary history of the tradition, and reception of a text. To the latter end, this paper proposes to go beyond the concept of translation, and focus on the Sanskrit concept of anuvada or “retelling” (and its later equivalent, “rewriting”), to show how this concept of “retelling” can contribute to a better understanding of literary history, especially in a country like India, where several linguistic traditions are organically connected. I shall primarily rely on The Mahabharata to substantiate my argument.

The aftermath of companies having failed abroad – Starbucks in Australia (US$ 105 million), Walmart in Germany (US$ 3 billion), Uber in China (US$ 2.4 billion), Best Buy in the UK (US$ 133 million), and Target in Canada (US $2.5 billion) – is an invitation to consider better ways of assessing companies’ compatibility with foreign cultures. An exploratory study testing the acceptance of a new product in the food industry demonstrated that cultural communities in the domestic markets could help companies to reduce the likelihood of rejection from foreign consumers by revealing the needed adaptations of their marketing strategies.
Mongolian Pastoralist Parents’ Experiences in Managing Their Primary School Children’s Living Arrangements
Authors: Sukhbaatar Batdulam , Tarkó Klára , Sukhbaatar Batkhand
Published: May 2024

Sending children, especially six-year-old ones, to school put pressure on pastoralist or herder households to balance their livestock herding needs and their children’s schooling needs at the same time. Due to remote campsites located in isolated rural areas far from any schools, pastoralists need to arrange a place for their children to stay during the school year. In this interpretive phenomenological study, we explored pastoralist parents’ experiences in managing different living arrangements for their primary school children during the school year. We conducted semi-structured interviews with five pastoralist parents from a remote county (an administrative division under a province) in Mongolia. Living arrangement options included staying in a boarding school dormitory, staying at a relative’s place, and staying with mothers in split households. The pastoralist parents’ own school experiences, the presence of first-grade school children, boarding school conditions, and family resources were found to be important factors for deciding the best living arrangement. We recommend that the government agencies should work on improving conditions of school dormitories and on providing better educational opportunities for pastoralists and their children.
Researching Emotional Experiences as Discursive Elements – A Suggested Qualitative Method

Published: May 2024

As scholars in the fields of political science, media research, and social psychology endeavor to understand crucial aspects of emotionality in the media, there is a growing need to methodologically address the communicative and discursive aspects of affective constructions in media texts. This article argues that by breaking down mediated emotional experiences represented through language in a set of identifiable elements, such as subject, emotion type, valence, intensity, proposed action, and object, those experiences could be used as workable and potent units of analysis when studying discursive and ideological media constructs of emotionality. By connecting insights from emotion science, the sociology of emotions, and media sociology, the qualitative method outlined, Emotional Experience Profiling (EEP), provides a flexible research tool conducive to an understanding of how emotional experiences represented through language in media texts are constructed and how they shape political discourse, identity, and emotional cultures. To demonstrate and illustrate the application of the method, the article provides examples from a pilot study which explores the research question: How do emotional experiences featured in Swedish far-right alternative news media construct and articulate political discourse?
