Background: Antimicrobial resistance (AMR) is a critical global health issue. Like other low- and middle-income countries, the misuse of antimicrobial medicine, including widespread self-medication, exacerbates AMR in Bangladesh. Making future generations aware of AMR through educational interventions is an effective tool in combating AMR. This research focuses on understanding the effects of AMR awareness interventions on the knowledge, attitudes, and behaviors of the schoolchildren in the selected district of Bangladesh. Methods: In this study, 241 students of the 12- to 16-year-old age group participated in a two-day program. The programs include four hours of activities, including reading comics and coloring books, presentations, quizzes, and watching an animation about AMR on the first day, followed by an art competition on the second day. To assess changes in knowledge earlier and after the intervention, pre- and post-tests were conducted. Results: This pilot study demonstrates that using age-appropriate interactive educational tools can significantly improve students’ knowledge about AMR, showing a mean difference of 1.28 (p < 0.001). The regulatory step of the Directorate General of Drug Administration, incorporating red identification marks on antibiotic packaging, makes it easier and shows that 93.36% of students could identify antibiotics, which helps them to be aware of these types of medicines. Interventions were equally effective for boys and girls and science and commerce students, and these helped participants recognize the inappropriate practices of antibiotic use in their daily lives. Conclusions: This study identified the importance of incorporating AMR issues into the educational curriculum to address AMR for future generations. Full article

Road construction has historically played a pivotal role in infrastructure development, addressing society’s growing mobility needs. Selecting sub-base and base layer aggregates requires materials that are mechanically durable, compliant with engineering standards, cost-effective, and sustainable. Locally sourcing aggregates enhances economic efficiency while reducing the environmental impact. In Southeastern Anatolia, particularly in Diyarbakır, extensive investments in roads, highways, and high-speed rail have increased the demand for high-quality aggregates. Karacadağ basalt, a locally abundant volcanic rock, offers a promising alternative. Its use not only reduces raw material costs but also aids in rehabilitating surface agricultural lands, supporting sustainable urban development and resource conservation. This study assesses the suitability of Karacadağ basalt as a sub-base and base material for highway construction. Two mixtures, namely PMT (Primary Mixture Type) and PMAT (Primary Mixture Alternative Type), were prepared and tested by the Ninth Regional Directorate of Highways using standardized methods including sieve analysis, methylene blue index, Los Angeles abrasion, Weather Resistance, and California Bearing Ratio (CBR) tests. Results indicate that Karacadağ basalt meets all relevant Turkish Highways Technical Specifications. These findings highlight the material’s potential as a sustainable, locally sourced aggregate for infrastructure applications, while suggesting that further testing across diverse quarry sites could enhance reliability and promote wider adoption.

American adults struggle with accurately assessing the quality of their diet, with the majority overrating their diet quality. Thus, the objective of the study was to explore what individuals think about when asked to rate their diet quality. Virtual focus groups were conducted from October 2023 to April 2024, using a semi-structured interview with open-ended questions. Convenience samples of small-scale farmers, school food service directors, health clinic patients, and university students and staff in Mississippi and Arkansas participated (N = 27). Themes and subthemes from NVivo-transcribed discussions were identified and coded inductively. Four subthemes emerged for description of diet: balance, consideration for others, convenience, and location. Four subthemes emerged for quality of diet: availability/access, culture/tradition, health considerations, and making better choices. Three subthemes emerged for healthy food: composition/preparation, nourishing benefits, and taste/flavor. Three subthemes emerged for unhealthy food: addicting/overconsumption, composition/preparation, and undesirable effects. Three subthemes emerged for nutrition knowledge: audience specific, general knowledge, and ambivalence. Three subthemes emerged for food shopping: food types, family influence/preference, and planning. Factors shaping how individuals perceive their diet quality are complex with intertwining components. Understanding the complexity involved in self-perceptions of diet quality will help us better quantify perceptions and link them to measurable outcomes. Full article

In 1906, Charles T. Currelly participated in excavations at Deir el-Bahri, Egypt, recovering votive offerings from the Temple of Hathor (Dynasty XVIII, reign of Hatshepsut, 1479–1458 BCE). These objects became part of the founding collection of the Royal Ontario Museum, where Currelly served as the first director. Among the offerings are several paintings on linen cloth. During examination of one painted textile, a border fringe with cream (suspected undyed), yellow and blue looped threads was sampled and analysed for dyes using gas chromatography–mass spectrometry. The yellow threads were found to contain a tannin-rich dyestuff, likely derived from Rhus spp., a common dye in ancient Egypt. Unexpectedly, the blue threads yielded brominated-indigoid marker compounds, indicating the use of a Murex-derived dye. While purple shellfish dye is rare due to the high cost of its complex production, blue shellfish dye is even more exceptional and has only been identified a handful of times on archaeological textiles. Calculated values of di-brominated to mono-brominated indigoid compounds suggests the dye originated from an indigotin-rich type of Hexaplex trunculus snail, a Mediterranean species. This finding represents a rare example of blue shellfish dye use in ancient Egypt and provides new insights into the dyeing technologies of Dynasty XVIII and the importance of this sky-blue colour in the worship of the goddess Hathor.

Background: The burden of type 2 diabetes mellitus (T2DM) in Tabasco from 2013 to 2023 has led to a significant loss in quality of life and life years. This study aims to analyze the impact of T2DM on the population of Tabasco, Mexico, during this period. Methods: A descriptive, observational, longitudinal, and retrospective study was conducted in Tabasco, following Feinstein’s guidelines. The study included 2,402,598 individuals, covering the adult study population of Tabasco (n = 927,047) based on National Institute of Statistics and Geography (INEGI) data. Data were gathered from the General Directorate of Health Information and the Ministry of Health and analyzed using Microsoft Excel, applying central tendency and dispersion measures, and calculating Disability-Adjusted Life Years (DALYs) with validated formulas. Results: DALYs in Tabasco’s adult population from 2013 to 2023 were 23,049 in 2013, 24,576 in 2014, 25,193 in 2015, 34,361 in 2016, 29,771 in 2017, 29,309 in 2018, 29,959 in 2019, 28,087 in 2020, 26,451 in 2021, 23,502 in 2022, and 30,523 in 2023, totaling 304,781 DALYs for the period. Conclusions: T2DM has shown an increase in incidence and mortality, especially in recent years, leading to a significant rise in DALYs. This reflects a higher disease burden in Tabasco compared to other regions in Mexico and the Americas, resulting in a considerable loss of quality of life and life years. Full article

One of the most important factors affecting water resources is livestock development. This study focuses on estimating the water demands of beef and dairy cattle breeding, as well as the corresponding products, in the Regional Unit of Karditsa (Greece), while simultaneously assessing the pollution caused by this activity in water bodies. The impacts are measured using the water footprint (WF) approach across its three dimensions (green, blue, and gray), considering the quantity of feed and water utilized by each animal type and the production system applied in the research area. For beef production, the intensive system shows a total WF of 90,535 m³/ton (gray 88%, green 9%, blue 3%), while the semi-intensive system totals 82,027 m³/ton (gray 84%, green 12%, blue 4%). For dairy cows, the total WF reaches 2750 m³/year/ton of milk (gray 81%, green 14%, blue 5%). Gray WF was estimated based on pollutant loads from livestock waste using concentration thresholds for biochemical oxygen demand (BOD₅), nitrogen (N), and phosphorus (P), providing a clearer view of water quality degradation linked to livestock activities. These findings can guide regional directorates in addressing key water-related pressures from livestock production. Full article

In the field of firms’ technological innovation, a large body of research has emphasized the roles of interlocking directors and the associated board networks in which they are embedded. By integrating the process perspective of absorptive capacity theory with stakeholder network theory, this study investigates the influence of board networks on firms’ technological innovation output, with particular attention given to the moderating effects of shareholder networks and CEO networks. The theoretical hypotheses suggest that degree centrality within board networks positively influences firms’ technological innovation output, and that this positive effect is weakened by degree centrality within both shareholder networks and CEO networks. While board networks facilitate information acquisition for technological innovation, shareholder networks and CEO networks may serve as substitutes. Furthermore, they may shape the motivations of shareholders and CEOs, potentially hindering the exploitation of information acquired through board networks. Using longitudinal data on Chinese A-share listed companies from 2005 to 2023, we construct three distinct types of interorganizational networks and annually measure firms’ degree centralities within each network type. Employing fixed-effects panel models, this study empirically verifies the proposed hypotheses. Practically, the findings offer important implications for firms seeking to align interorganizational networks with their technological innovation management strategies. We recommend that future research further explore the roles of diverse stakeholder networks in interorganizational contexts to enhance the understanding of how interactions across multilayer networks affect firms’ technological innovation output.

Ferroelectric liquid crystals (FLCs) are key materials for high-speed electro-optical applications, yet achieving optimal properties over a broad temperature range down below room temperature remains a challenge. This study presents a novel series of systematically designed FLC mixtures, incorporating components with three degrees of chirality—achiral systems, with one center of chirality and with two centers of chirality—to optimize the mesomorphic stability, electro-optical response, and physicochemical properties. The strategic doping by chiral components up to a 0.2 weight fraction extends the temperature range of the ferroelectric phase while lowering the melting temperature. Notably, mixtures containing two chiral centers exhibit shorter helical pitches, while increasing chirality enhances the tilt angle of the director and spontaneous polarization. However, in a mixture containing all three types of chirality (CchM), spontaneous polarization decreases due to opposing vector contributions. Switching time analysis reveals that a system with achiral components and those with two centers of chirality (A-BchM) exhibits the fastest response, while CchM demonstrates only intermediary behavior, caused by its high rotational viscosity. Among all formulations, those containing compounds with two centers of chirality display the most favorable balance of functional properties for deformed helix ferroelectric liquid crystal (DHFLC) applications. One such mixture achieves the lowest melting temperature reported for DHFLC-compatible FLCs, enabling operation at sub-zero temperatures. These findings pave the way for next-generation electro-optical devices with enhanced performance and appropriate environmental stability. Full article

Persistent atrial fibrillation (AF), a prevalent cardiac arrhythmia, is primarily sustained by rotor-type reentries, with their localization crucial for successful ablation treatment. Fractionated atrial electrogram (EGM) signals have been associated with the tips of the rotors and are thus considered as ablation targets. However, the typical noise problems of physiological signals affect the results of EGM processing tools, and consequently the ablation outcome. This study proposes a data fusion framework based on the Joint Directors of Laboratories model with six levels and information quality (IQ) assessment for locating rotor tips from EGMs simulated in a two-dimensional model of human atrial tissue under AF conditions. Validation tests were conducted using a set of 13 IQ criteria and their corresponding metrics. First, EGMs were contaminated with different types of noise and artifacts (power-line interference, spikes, loss of samples, and loss of resolution) to assess tolerance. The signals were then preprocessed, and five statistical features (sample entropy, approximate entropy, Shannon entropy, mean amplitude, and standard deviation) were extracted to generate rotor location maps using a wavelet fusion technique. Fuzzy inference was applied for situation and risk assessment, followed by IQ mapping using a support vector machine by level. Finally, the IQ criteria were optimized through a particle swarm optimization algorithm. The proposed framework outperformed existing EGM-based rotor detection methods, demonstrating superior functionality and performance compared to existing EGM-based rotor detection methods. It achieved an accuracy of approximately 90%, with improvements of up to 10% through tuning and adjustments based on IQ variables, aligned with higher-level system requirements. The novelty of this approach lies in evaluating the IQ across signal-processing stages and optimizing it through data fusion to enhance rotor tip position estimation. This advancement could help specialists make more informed decisions in EGM acquisition and treatment application. Full article

This study analyzes the award-winning documentary film Searching for Rodakis, directed by Kerem Soyyilmaz, produced in 2023. The aim of this study is the historic comprehension and analysis of this filmic narrative in the field of social–semiotic literacy and its utilization in historical studies for approaching issues of conflict in modern history, otherness, collective experience and trauma, and collective memory. The research material is the documentary Searching for Rodakis (produced by Denmark, Turkey 2023; screenplay/director, Kerem Soyyilmaz; duration, 57’), which received the following awards: Adana Golden Boll FF 2023 Turkey | Best Documentary, Thessaloniki International Doc. Festival 2023 Greece, Greek Film Festival Los Angeles 2023 USA, and Istanbul Documentary Days 2023 Turkey. As regards the historic context, the year of production, 2023, coincides with the 100th anniversary of the signing of the Treaty of Lausanne, where Turkey’s current borders were set and the “population exchange” legally sealed, i.e., the violent expulsion of 400,000 Muslims, citizens of Greece, many of whom spoke only Greek, and 200,000 Orthodox citizens of Turkey, who in the majority spoke Turkish. At the same time, the Treaty of Lausanne ratified and finalized the expulsion of approximately one million Orthodox who were forced to leave the Ottoman Empire, as well as 120,000 Muslims who had fled Greece since the beginning of the Balkan Wars (1912–1913). About two million people were deported and lost their citizenship and property, in the context of “national homogeneity” (which connotes an ethnic cleansing), with the official states ignoring the criticisms of lawyers and academics who spoke of violations of constitutional rights. Mohammedan Greeks, estimated at around 190,000 as early as 1914, based on ecclesiastical statistics in the Pontus region, did not receive attention from the provisions of the Treaty of Lausanne, even though linguistically and culturally (origin, customs, culture and traditions) they did not differ in any way from the Orthodox Greeks. In Turkey, there was general indifference to the thousands of desperate people who arrived, with the exception of a few academics and the Lausanne Exchange Foundation. The filmic scenario is as follows: as a Greek tombstone of unknown origin is discovered underneath the floorboards in an old village house in Turkey, an almost forgotten story from the country’s creation unravels—the forced population exchange between Greece and Turkey in 1923. The engraved Greek letters tell of a woman, Chrysoula Rodaki, who died in 1887. Thus the search for her descendants begins. It leads director Kerem Soyyilmaz to local archives, where his own family’s role in history is laid bare; to abandoned ghost towns, and through the memories of older villagers—all while Soyyilmaz meets massive support for his quest from Greeks on the other side of the border. The stone becomes a portal to the past—and for a while, the trauma becomes redeemed when the previous owners of the village house return. Searching for Rodakis is a movie that reconnects people, culture, and the stories that were discarded in order to build a strong, nationalist state—told through the director’s personal experiences. The research questions, as they arise from the cinematographic material itself, are as follows: How is the historical memory of traumatic events of the previous century, such as the exchange of populations according the Treaty of Lausanne, recorded in the cinematographic narrative? What are the historical sources? To what extent did the origin, ethnicity, and geographical location of the narrators as participants influence the preservation of historical memory and the historical research? What are the criteria of the approach of the creator, and what are the criteria of the participants? Methodologically, we apply historic and socio-semiotic analyses in the field of public and digital history. The results: The types of historical sources found in filmic public discourse include the oral narration of testimonies, of experiences and of memories, as well as the director’s historical research in state archives, the material cultural objects, and the director’s digital research. Thus, historic thematic categories occur, such as the specific persons and actions in Turkey/Greece, actions on-site and in online research, and the types of historical sources, such as oral testimonies, research in archives, and objects of material culture. Sub-themes such as childhood, localities and kinship also emerge. These cinematic recordings of biographical oral narratives as historical and sociological material help us understand the political ideologies of the specific period, between the years 1919 and 1923. The multimodal film material is analyzed to provide testimonies of oral and digital history; it is utilized to approach the historical reality of “otherness”, seeking dialogue in cross-border history in order to identify differences, but above all the historic and cultural similarities against sterile stereotypes. The historic era and the historic geography of the Greek and Turkish national histories concern us for research and teaching purposes a hundred years after the Treaty of Lausanne which set the official borders of the countries.

The transition towards a sustainable mobility model encourages an increase in the use of soft modes of transport, and thus an increase in the number of vulnerable road users, especially in urban areas. In Spain, this group of users, comprising pedestrians, cyclists, users of personal mobility vehicles and motorcyclists, accounted for 62,258 victims in road accidents in 2023, 46% of the total, with 7258 dead or seriously injured representing 65.6% of the total. Different strategies to protect vulnerable road users, including communication campaigns, are regularly developed to increase safe travel behaviour. In this context, this study analyses the campaigns issued by the Directorate General of Traffic since 1960 aimed at vulnerable road users. Only 28 campaigns met the established inclusion criteria, representing 23.5% of the total. Thus, the period 2011–2024 has seen the lowest prevalence of this type of campaign, coinciding with a context characterised by the emergence of new forms of micro-mobility that are more sustainable but also more exposed to risks. Due to this complex environment, it is recommended to increase the prevalence of campaigns targeted at vulnerable users and to maximise their effectiveness using emerging technologies such as artificial intelligence and big data, and delivered through a combination of traditional and digital media.

IPCC climate forecast models, applicable to the Maghreb countries (Morocco, Algeria, and Tunisia), predict a decrease in atmospheric precipitation, greater variability, and an increase in aridity. In recent years, the entire region has been experiencing unprecedented climate upheavals. Climatic droughts have become increasingly severe and recurrent (drastically reducing water stocks). We are also witnessing a remarkable increase in temperatures and a greater frequency of heat waves. Faced with these new provisions, this territory (long considered an area of water stress) is now subject to very strong tensions, which have led to a greater demand for water and a decrease in supply. To understand the intensity of this “climate–water” crisis, we propose an analysis of this priority issue based on the evolution of precipitation over more than half a century of records. To determine precipitation trends and define rainfall cycles in these three countries, the graphical chronological method of information processing (MGCTI) of the “BERTIN Matrix” type is used. Annual precipitation totals from 29 stations were used for the MGCTI (chronological graphic method of information processing) for the period 1970–2023. These data come from the national meteorological networks of the National Meteorological Office (ONM) for Algeria, National Institute of Meteorology (NIM) for Tunisia, and National Directorate of Meteorology (DMN) for Morocco, and the from the websites of the National Climatic Data Center (NCDC) and “TuTiempo Network”. Monthly pluviometric totals from three stations, Dar El Beida (Algeria), Casablanca (Morocco), and Tunis (Tunisia), as well as the monthly NAO (North Atlantic Oscillation) and MOI (Mediterranean Oscillation Index) were used for the wavelet coherence method for the period 1970–2022. Data analysis shows that the entire region is subject to four extreme precipitation cycles (dry and wet). The last dry period was remarkably intense and led to a sharp increase in water stress throughout the region. An analysis of monthly precipitation from three stations (Casablanca, Dar El Beida, and Tunis) using the wavelet coherence method also highlighted a close relationship with the “NAO” and “MOI” circulation.

This study empirically examines the determinants of merger and acquisition (M&A) activities in Vietnam from 2005 to 2020, which has not been examined before, using a fixed-effects model for a sample of 674 completed M&A deals. The results indicate that targets’ corporate governance and deal characteristics have mixed effects on M&A decisions. More specifically, the independent member of the board and CEO duality of the target is negatively associated with most M&A types, except for cross-border mergers. However, the impact of targets’ blockholders is consistently positive regardless of M&A types. When observing the deal characteristics, mixed evidence is also found in the case of M&A payment form, industry-relatedness between the bidder and the target, the bidder’s stake in the target, and foreign ownership in the bidder’s stake. More interesting, our study emphasizes that voluntary agreement is seemingly critical to M&A decisions regardless of different types. Our results suggest several important implications, including balancing independent directors on the board, accounting for CEOs’ and other blockholders’ interests and influence, considering the types of M&A payments, and involving foreign investors in M&A activities. By understanding these implications, firms can better navigate the complexities of M&A transactions, enhancing their decision-making processes and ultimately contributing to improved shareholder value.

This article uses the English Gothic’s eighteenth-century dismantling of male lineage and Enlightenment certainty in Horace Walpole’s The Castle Otranto as a lens for understanding the twenty-first-century commercial popularity of director Mike Flanagan’s Gothic films, particularly Doctor Sleep. Building on Stephen King’s 2013 novel and Stanley Kubrick’s 1980 film The Shining, Flanagan’s Doctor Sleep establishes a new lineage of male writers who value how the Gothic traditions of irrational emotion and doubt can inspire new realms of knowledge to lessen psychological suffering caused by traumatic lineage. By “traumatic lineage” I mean the threat and violence some find necessary to maintain the patrilineal claim that it is “naturally” the only way to organize society. Like Walpole’s mythopoeic Gothic novel, Flanagan’s Gothic films demonstrate how patrilineal lineage damages other men, not just women; thus, Flanagan’s films offer psychological workbooks for practicing a type of reparative masculinity that involves exposure-exercises of cognitive behavior therapy (Doctor Sleep’s “boxing” intrusive, traumatic memories), male communities of care, and interdependent empathy. I support this argument by closely reading how Flanagan’s filmic tools of domestic metaphor, uncanny casting, and repurposed sets from Kubrick’s The Shining not only tell how to exorcise the inherited stills of the Overlook Hotel but also show viewers how to do so. We experience Dan Torrance’s reparative masculinity in real-time, communally sharing and recasting Dan’s horrific images of 40 years ago, but we now relate to them in psychologically helpful ways that enable community. In this way, I illustrate and encourage future study of how Gothic texts not only point to marginalized, repressed problems, but more importantly, how they help us relate differently to a traumatic past and innovate strategies for immediate relief from inherited suffering.

The coast is the most dynamic part of the Earth’s surface due to its strategic position at the interface of the land and the sea. It is, therefore, exposed to hazards and specific risks because of the geography as well as the geological and environmental characteristics of different countries. The coastal environment is essentially dynamic and evolving in time and space, marked by waves, tides, and seasons; moreover, it is subjected to many marine and continental processes (forcing). This succession of events significantly influences the frequency and severity of coastal hazards. The present paper aims at describing and characterizing the hazards and vulnerabilities on the Cameroonian coast. Cameroon possesses 400 km of coastline, which is exposed to various hazards. It is important to determine the probabilities of these hazards, the associated effects, and the related vulnerabilities. In this study, in this stable intraplate setting, the methodology used was diverse and combined techniques for the study of the shore and methods for the treatment of climatic data. Also, historical data were collected during field observations and from the CRED website for all the natural hazards recorded in Cameroon. In addition, documents on climate change were consulted. Remotely sensed data, combined with GIS tools, helped to determine and assess the associated risks. A critical grid combining a severity and frequency analysis was used to better understand these hazards and the coastal vulnerabilities of Cameroon. The results show that Cameroon’s coastal margins are subject to natural processes that cause shoreline changes, including inundation, erosion, and accretion. This study identified seven primary hazard types (earthquakes, volcanism, landslides, floods, erosion, sea level rise, and black tides) affecting the Cameroonian coastline, with the erosion rate exceeding 1.15 m/year at Cape Cameroon. Coastal populations are continuously threatened by these natural or man-induced hazards, and they are periodically subjected to catastrophic disasters such as floods and landslides, as experienced in Cameroon. In addition, despite the existence of the National Contingency Plan devised by the Directorate of Civil Protection, National Risk, and Climate Change Observatories, the implementation of disaster risk reduction and mitigation strategies is suboptimal.
