Effect of Treatment With Balanced Crystalloids Versus Normal Saline on the Mortality of Critically Ill Patients With and Without Traumatic Brain Injury: A Systematic Review and Meta-Analysis
Authors: Diz José C. , Luna-Rojas Pedro , Díaz-Vidal Pablo , Fernández-Vázquez Uxía , Gil-Casado Cristina , Diz-Ferreira Eva
Published: January 2025

BACKGROUND:

Some studies suggest that balanced solutions may improve outcomes in critical care patients. However, in patients with traumatic brain injury (TBI) existing data indicate that normal saline may be preferred. We hypothesized that mortality in critically ill patients with and without TBI would differ with the use of balanced salt solutions versus normal saline.

METHODS:

We conducted a systematic review and meta-analysis to investigate the impact of balanced crystalloids versus normal saline on 90-day mortality in adult critical care patients with and without TBI. Secondary outcomes included length of hospital stay, renal complications, need for vasopressors or mechanical ventilation, and mortality in critically ill patients with sepsis. We followed the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analysis) statement and estimated the odds ratio (OR) and 95% confidence interval (CI) with a random-effects model.

RESULTS:

We included 15 clinical trials involving 35,207 patients. The OR of mortality with balanced solutions versus saline in patients without TBI was 0.93 (95% CI, 0.87–0.98; P = .01; I2 = 0%), while the OR for mortality in patients with TBI was 1.31 (95% CI, 1.03–1.65; P = .03; I2 = 0%). We found no differences in secondary outcomes due to fluid choice although data were unavailable to calculate pooled estimates for some of the secondary outcomes for TBI patients. In patients with sepsis, the OR of mortality with balanced solutions was 0.92 (95% CI, 0.83–1.02; I2 = 0%).

CONCLUSIONS:

In comparison to normal saline, balanced solutions were associated with a reduction in mortality in critical care patients without TBI. However, balanced solutions were associated with an increase in mortality in patients with TBI. These findings suggest that the effect of fluid choice on intensive care unit (ICU) outcomes may depend partially on the type of critical illness and in particular in patients with TBI.

Published: January 2025

Purpose This study evaluated the effectiveness of integrating Chinese checkers into Comparative Politics courses across Asia-Pacific universities during 2021-2022, examining its impact on students’ strategic thinking, negotiation skills, and academic performance. Methods The research employed paired and independent-samples t-tests to assess academic outcomes among 93 students who played Chinese checkers versus 86 control participants. Assessment metrics included strategic thinking capabilities and overall course performance. Findings Students who participated in Chinese checkers demonstrated statistically significant improvements in strategic thinking (p < 0.05) and achieved higher academic scores (M = 4.38, SD = 0.18) compared to the control group (M = 3.87, SD = 0.13). Significance This study establishes Chinese checkers as an effective pedagogical tool for developing strategic thinking in undergraduate political science education. The findings support incorporating game-based learning approaches to enhance critical thinking and negotiation skills for understanding Asia-Pacific politics.

Published: January 2025

Background Technological advancements, such as the introduction of 5G, offer opportunities but also raise concerns. Although no evidence suggests negative effects of radiofrequency electromagnetic fields (RF-EMF) within defined exposure limits, authorities responsible for risk communication provide precautionary advice to help citizens reduce personal exposure. However, previous research indicates that precautionary information can increase risk perception and decrease trust. Methods This cross-sectional study investigated effects of precautionary information on risk perception and trust in the context of 5G, using large general population samples in Germany and Greece. For the first time, personal relevance was examined as a potential moderating factor, using a novel approach to assess practical and thematic relevance. Participants were first surveyed on their relevance of the topic, then provided with basic information about “RF-EMF and health”, and, in the experimental group, with additional precautionary information. Different measures for risk perception and trust followed. We expected higher risk perception and lower trust for the experimental group, and assumed that at lower personal relevance, this effect would be stronger. Results Contrary to expectations, precautionary information increased just one risk perception measure and only in Germany. The anticipated moderating effect of personal relevance was not found, but relevance itself significantly predicted risk perception, with higher relevance correlating with higher risk perception. Exploratory findings revealed higher risk perception among females compared to males and in Greece compared to Germany. Conclusions That there were only few effects of the precautionary information may be linked to the focus on actions to reduce personal exposure when using mobile devices. The results underline the importance of considering personal relevance and demographic factors in risk communication and highlight directions for future research.

Authors: Alent'eva Tat'yana , Malina Viktoriya
Published: January 2025

The monograph examines the problems of creating and developing the US national Park system. Currently, there are practically no studies in Russian historiography specifically examining the experience of their history and functioning. Researchers K. Burns and D. Dayton named national parks the "Best idea of America". The evolution of their development is described on a broad historical basis, starting from the second half of the 19th century, when the first national parks of the USA were created, until the 2020s. The book examines the socio-cultural conditions of the creation of a system of national parks. For the first time in historiography, the legislative framework for the activities of national parks has been analyzed, and the history of the creation and activities of the National Park Service, which turned 100 years old in 2016, has been described in detail.
Separate sections are devoted to natural national parks, including the first national parks, Yosemite and Yellowstone. Historical national parks are covered in some detail, which is undoubtedly of great interest to Russian readers, since they have not been given due attention in domestic American studies. National natural and historical parks perform a number of important functions, including conservation, recreational and educational.
It is intended for specialists, students, bachelors, masters, as well as anyone interested in the problems of history, ecology, and tourism.

Published: January 2025

According to the official educational curricula, formal financial training in Spain has
been and still is limited. Consequently, the level of financial competences of Spanish students in
their last year of high school remains below the average level of OECD’s countries.
This research aims to highlight the importance of complementing the formal high school education
with non-formal activities. Such non-formal activities could help in the acquisition of economicfinancial knowledge and skills at an early age.
Specifically, an activity based on a game denominated “Ranoka” was designed and
implemented to contribute to enhancing the financial literacy levels of young people. Therefore,
our challenge is to increase the level of financial competence in a fun way to capture the attention
of these young students when faced with content that might be tedious or unattractive for them.
The activity was carried out in 2021 in the Southwest of Andalusia. Five different educational
institutions and a total of 224 students from the last course of mandatory high school in Spain
participated in the activity. The participants valued positively the proposed activity with an
average score of 8.4 points out of 10.

RELIGIÓN, LOCURA Y SEXUALIDAD EN VIRIDIANA Y THE VVITCH.
Authors: Pérez Flores José Luis , De Aro Espinosa Estefanía
Published: January 2025

En este trabajo discutimos la representación cinematográfica de la mujer y la locura. Para
ello acudimos a la mirada de Buñuel y Eggers que a través de sus filmes relatan el
rompimiento de la psique de sus protagonistas, mostramos cómo la mujer transita de la
idealización como un ser débil, delicado, virginal a una entidad maligna, demoniaca,
desmesurada y altamente sexualizada. En nuestro análisis comparamos ambas películas
con el propósito de argumentar cómo los dos directores tienen una actitud crítica ante la
religiosidad católica y puritana, pero no ofrecen una mejor alternativa más que el
pesimismo.

Durante muchos años, el tema de “la locura” estuvo revestido de prejuicios no solo en la
sociedad mexicana, sino también en el propio ordenamiento jurídico mexicano, que en
sus inicios no contaba con mayores consideraciones hacia las personas aquejadas por tal
condición, por tanto, la impartición de justicia era irregular y sometida muchas de las
veces al arbitrio del juzgador, por lo que se tuvo que recurrir a los peritajes médicos.

Dynamika współczynnika dzietności na tle przemian społeczno-kulturowych w Republice Korei
Authors: Guzik Joanna M.
Published: January 2025

The Republic of Korea is one of the countries that has undergone an accelerated change in the last few decades in cultural and social, economic as well as political dimensions as part of Huntington’s third wave of democratisation. The transformation of this war-ravaged country into an economic tiger3 was accompanied by a change in demographic indicators4, which soon began to reveal the effects of the demographic transition. One such indicator is the meager birth rate, particularly the Total Fertility Rate (TFR), which, according to official figures for 2022, is 0,778 children per woman of childbearing age. Hence the aim of this article is to show the cultural and social changes in Korea regarding gender equality in the context of theories of demographic transitions, the status of Korean women in traditional and contemporary terms, their rights, and their participation in the labour market together with the educational context that prepares them for it, and their reluctance to pay a kind of debt to previous generations as some of the reasons for the decline in the number of children born are presented. It was hypothesised that fertility rates are declining as a result of a re-evaluation of life priorities and mainly through procrastination or even unwillingness to marry, combined with women’s struggle for their rights and against discrimination, all of which exacerbate gender conflict in Korea.

This research aims to solve the problem of why Korean series directors choose to introduce supernatural creatures from the native folklore into the realm of cinema.
El despliegue de China en América Latina: debates desde la Economía Política Internacional Latinoamericana
Authors: Quiliconi Cintia , Vergara Monica
Published: January 2025

Este artículo examina los principales debates en la Economía Política Internacional (EPI), particularmente en América Latina, sobre la creciente presencia económica de China en la región. A través de una exhaustiva revisión de más de 90 documentos publicados entre 2004 y 2024, y utilizando un sistema de cocitas, nodos y conexiones entre trabajos, se clasificó la literatura en tres enfoques centrales: Dependencia, Complementariedad/Interdependencia y Globalización con Características Chinas (GCC). Los resultados muestran una marcada división en el debate. Por un lado, están quienes se enfocan en la perspectiva tradicional de la dependencia, subrayando el intercambio comercial con China y la tendencia hacia la reprimarización. Por otro lado, algunos ven oportunidades de complementariedad entre la región y China, considerando las ventajas comparativas de ambos actores. Finalmente, existe un eje en desarrollo que considera las dinámicas actuales como una gcc, y sugieren una nueva forma de cooperación, distinta a los preceptos de hegemonía occidental. Como conclusión, se identifica algunos vacíos en los debates actuales, que podrían ser cruciales para comprender la evolución de las relaciones sino-latinoamericanas, como el proceso de aprendizaje de actores chinos, principalmente empresas e instituciones financieras, que podría explicar parte de los cambios de su comportamiento en la última década.
Innovation Diffusion Among Coworkers: Evidence from Senior Doctors

Published: January 2025

Using a novel 15-year data set on surgeon adoption of a complex surgical innovation in the English National Health Service and an identification strategy based on surgeon mobility, this paper disentangles three channels of coworker influence on innovation diffusion: (1) peer network size, (2) influential “key players,” and (3) cumulative peer adoption. We find that a one standard deviation in peer connections boost innovation by 16%. Key players can either amplify or dampen diffusion, and peer adoption has a greater impact on less experienced individuals. These results highlight the value of targeting training to high impact network members to speed up diffusion. This work advances our understanding of how professional networks shape innovation diffusion, with implications for technology implementation.

Central Jakarta as one of the administrative cities in the DKI Jakarta Province has the highest populationdensity of 20,360 per km2. The number of motorized vehicles in Jakarta is recorded at 23,025,101 units. Thisfigure can be a crucial issue considering that the transportation sector is the largest contributor to airemissions with PM2.5 as the main pollutant. Jakarta's air quality is monitored as unhealthy (for sensitivegroups) with PM2.5 concentrations reaching two and a half times the safe limit according to WHO standards.This study aims to determine the percentage of interest of private vehicle users in the M.H Thamrin Area,Central Jakarta switch to pedestrians or bike. The result were then be used to calculate the emissions thatoccur reduction followed by the changes. The survey’s result were analyzed using the SPSS application todetermine significant factors related to the interest of private vehicle users to switch. Emission calculationsare carried out based on the Regulation of the Minister of Environment No. 12 in 2010. The result of thisstudy indicate that 91.5% of private vehicle users from 12,830 residents of the M.H. Thamrin area are willingto switch to pedestrians consisting of 65.1% motorcycle users and 34.9% car users. As many as 94.4% ofprivate vehicle users are willing to switch to bike sharing consisting of 63.2% motorcycle users and 36.8%car users. Several factors that significantly influence people's interest in switching are the availability of widepedestrian paths (> 2 m) and the low cost of using bike sharing (Rp3,000 - Rp7,000 per trip). With the effortto move private motor vehicles to pedestrians, PM2.5 emissions in the M.H. Thamrin Area, Central Jakartacan be reduced by 93.04%, which is equivalent to 0.656 tons of PM2.5/year. On the other hand the shifting ofprivate motor vehicles to bike sharing, will contribute to 92.87% of PM2.5 reduction, or 0.778 tons ofPM2.5/yea

Authors: Parmar Nidhi , Virdi Rajkaran Singh
Published: January 2025

Ectodermal dysplasias (ED) are a group of genetic disorders, of which common oral presentations include severe hypodontia and conically formed anterior dentition. With the average ED patient missing 23.7 permanent teeth, the ramifications of severe hypodontia directly correlate with quality of life and treatment complexities. The aim of prosthodontic rehabilitation is to provide an age-appropriate dentition to aid aesthetics, phonetics, masticatory and psychosocial development, recommended for commencement at an early age, including support throughout life. This case report demonstrates a non-invasive, simple and predictable approach to the prosthodontic rehabilitation of a 9-year-old child with ED affected by severe hypodontia.

CPD/Clinical Relevance: Non-surgical prosthetic treatment can be a safe and predictable first-line treatment for the oral rehabilitation in patients with hypodontia.

Published: January 2025

The lack of information regarding the existence of potential natural resources supporting tourism activities and the suitability and capability of resources to support the implementation of good tourism activities can be a factor that hinders the sustainability of tourism in Kurenai Beach. Beach tourism activities can make a positive contribution to economic growth and the level of community welfare. On the other side, these activities also negatively impact the sustainability of coastal resources. For this reason, it is necessary to limit the tourists according to the carrying capacity of Kurenai Beach. This research gave the initial information to support the sustainability and management of Kurenai Beach tourism, Bone Bolango Regency. This research aims to determine potential resources through regional suitability and carrying capacity. Further, it is expected that the result of this study can be used as a recommendation in preparing a tourism development policy plan for Kurenai Beach, Bone Bolango Regency. The research was conducted from March to August 2023 in Tomini Bay waters, Kurenai Beach. This is a survey and interview research. The types of data used in this research were primary and secondary. The analysis used in this research was suitability analysis and carrying capacity analysis to determine the resource potential of Kurenai Beach. The research results showed that the suitability of Kurenai Beach tourism in the beach recreation category was divided into 3 (three) suitability categories, namely very suitable (S1), suitable (S2), and not suitable (S3). The carrying capacity of the Kurenai Beach tourist area could accommodate around 33,840 people/month. Kurenai Beach has some potential resources that are very suitable for beach tourism, amounting to 15,379 m2 and the total visitors of Kurenai Beach has not exceeded the carrying capacity of the Kurenai Beach tourist area so optimizing its use and management is highly possible.Keywords:Natural resourcesSustainable tourismTomini BayBotubarani Village

Published: January 2025

One of the regions contributing to stingray fisheries production in Indonesia is Aceh province. The condition of stingray fisheries in Indonesia is currently facing challenges as the population is decreasing while the demand for stingray fishery resources domestically and abroad continues to increase. This condition certainly requires integrated stingray fisheries management efforts so that the rays’ population, especially in the waters of Aceh province, remains sustainable. This study aimed to determine the number, type, and distribution of stingray fishing grounds landed at the Ujong Baroh Fish Landing Base (PPI). The research was carried out in 2 stages; the first stage was to conduct a field survey by following fishermen directly to the sea and using interview questionnaires, and the second stage was to take satellite image data of sea depth, fishing location, and fishing distance and then make a map of stingray fishing ground distribution landed at Ujong Baroh Fish Landing Base, West Aceh. The number of stingray catches landed at Ujong Baroh Fish Landing Base during the study was 428, consisting of 11 species: 369 Maculabatis macrura, 42 Myliobatis tobijei, 14 Rhynchobatus australiae, 28 Dasyatis kuhlii, 8 Pateobatis uarnacoides, 7 Gymnura zonura, 6 Himantura leoparda, 2 Rhina ancylostoma, 2 Rhinobatos borneensis, 1 Aetobatus narinari, and 1 Taeniuriops meyeni. The results of the mapping analysis showed 18 distribution points of stingray fishing grounds and 4 fishing locations that obtained stingray catches, namely at the coordinates of 3°38.136'N and 96°29.056'E, 4°2.144'N and 96°2.431'E, 4°16.599'N and 95°32.000'E, 3°34.51472'N and 96°25.80414'E.Keywords:MappingFishing GroundStingrayEastern Season

Authors: Kadim Miftahul Khair , Pasisingi Nuralim
Published: January 2025

Activities around Bone River, one of the largest rivers in Gorontalo Province, include agriculture, settlement, gold mining, sand excavation, industry, and illegal logging. This research aimed to report the water quality status of Bone River using the STORET method as an index commonly used for measuring pollution levels in a water body, which the Indonesian government regulates, as stated in the Decree of the Minister of Environment, No. 115, 2003. This work involved data from 2021-2023 along the upstream to downstream of the river. There were 12 water quality parameters measured: temperature, TSS, DO, pH, COD, BOD, nitrate, phosphate, ammonia, and the heavy metals (Pb, Cd, and Hg) concentration. This study revealed that parameters met water quality standards for class I and class II: temperature, pH, DO, Pb, and Cd. The index scores ranged from -96 to 0. The upstream area was categorized as good, and the midstream to downstream was recognized as heavily polluted. This pollution level is dominated by organic waste from agricultural and domestic household activities. The concentration value consistently exceeds the quality standard in all data from St 5 to St 12. These two parameters are enough to significantly cause worsening water quality based on the STORET with a total score contribution of -40. BOD and COD parameters contribute the most to the river pollution level.Keywords:Water qualityPollutionSTORETBone River

Characteristics of plastic debris were assessed among two types of beaches on Bawean Island (windward and leeward) to analyze its sources and long-term effects. Plastic debris was collected inside a 5 x 5 meter transect with five transect plots on each beach per 20 meters. Samplings were carried out three times at intervals of seven days from six different beaches. The average abundances of plastic debris were almost similar between leeward (0.169±0.123 pcs m-2) and windward beaches (0.841±0.577 pcs m-2). On the other hand, in terms of weight, leeward beaches contained a very low value of debris (0.927±0.746 g m-2) compared to windward beaches (4.479±3.551 g m-2). Sheets on the windward beaches and wholes on the leeward beaches dominate the shape of plastic debris with the average size was 15–20 cm. The color on both type of beaches was dominated by white (38%) and blue (12%). The weathering intensity is 48% on the leeward beach and 52% on the windward beach. The absence of significant differences in size, color, and weathering intensity implies that the debris found came from the same source. The large size and low weathering intensity of the plastic debris means that the debris has not been exposed to hydro-oceanographic factors for an extended period and they came from a local source. The difference in abundance and shape of plastic debris suggests that wind still plays a vital role in shaping the characteristics of plastic debris on Bawean Island.Keywords:Marine DebrisPlastic WeatheringWind DirectionMarine PollutionMacroplastic

The marine ecosystems in the southern part of Rote Ndao District, within the Timor Sea, could be harmed by oil spills from ships or offshore rigs operated by oil and gas companies in the Timor Sea block, shared by Indonesia, Australia, and Timor Leste. The assessment using Environmental Sensitivity Index (ESI) maps using the thematic data. Areas identified as most sensitive to oil spills include West Rote district (Boa and Nembrala villages), and Southwest Rote district (Oeseli, Landu, and Manuk villages and Ndana islands). The beach type in Rote Ndao which is dominated by sloped sandy beach is a substrate type that is easy to clean from oil spill. Conversely, the biodiversity component has the highest sensitivity. The socio-economic components that are most sensitive to the effect of oil spills are the main sources of livelihood include seaweed cultivation, fisheries, and marine tourism. Oil spill mitigation in Rote Ndao must be focused on oil spill risk management in the hotspot area based on the environmental sensitivity index. A plan to prevent oil spills can be created, targeting these hotspots to establish an early warning system for effective mitigation.Keywords:Environmental sensitivity indexoil spillRote Ndaobiodiversityrisk management

The community's need for saline tilapia seeds (Oreochromis niloticus) until now still shows a significant increase, the development of tilapia aquaculture business is growing from the sector of breeding and enlargement. This study aims to determine the level of hatchability of saline tilapia eggs (Oreochromis niloticus) with different containers to provide alternatives to the community in using saline tilapia egg hatching containers This research was conducted at the Laboratory of the Fish Seed and Feed Production Technology Study Program of the Polytechnic of Indonesia Venezuela (POLIVEN) in March-April 2024. The research method used was an experimental design, namely a non-factorial Completely Randomized Design (CRD) consisting of 4 treatments, namely A (using a gallon), B (using a teapot), C (using a chicken drinking funnel), D (using a flower pot) each carried out 5 times with test parameters including egg hatchability, larval abnormality, and water quality parameters. Based on the research that has been done, the highest degree of egg hatching is in treatment C (chicken dringking funnel) with a value of 92% an the lowest is in treatment D (flower pot) with a value 51%. The highest larva abnormality is in treatment B (teapot). The annova test result showed that the application of different containers on egg hatchability had a significant effect on the hatching of saline tilapia eggs (Oreochromis niloticus). Based on the results of Duncan's further test showed that the treatment of chicken drinking funnel with 92% percentage is the best treatment compared to other treatments.Keywords:AbnormalityHatchabilityWater qualityTilapia Fish

Gelatin, a valuable biopolymer, is commonly derived from animal by-products such as fish skin, providing a sustainable alternative to traditional bovine and porcine sources. The extraction process is influenced by factors like acid type and temperature, which impact both yield and quality. This study aimed to compare the effects of citric acid and acetic acid, at two temperatures (50°C and 60°C), on the gelatin extracted from yellowfin tuna (Thunnus albacares) skin. The extracted gelatin was evaluated for yield, proximate composition, functional groups using FTIR, and surface morphology through SEM. Results indicated that acetic acid produced a significantly higher yield than citric acid at both temperatures, with the highest yield (10.10%) at 50°C and the lowest (2.46%) from citric acid at 60°C. Gelatin extracted with acetic acid also had higher protein content and lower moisture and ash levels. FTIR analysis confirmed the presence of characteristic gelatin functional groups, including Amide I, II, and III. SEM images showed a denser and more uniform structure in acetic acid-extracted gelatin, while gelatin extracted with citric acid had a more porous and irregular surface. SDS-PAGE analysis revealed stronger protein bands for gelatin extracted with acetic acid, indicating higher protein content and a more efficient extraction process. Both acid-extracted gelatins showed α-chains and β-chains, characteristic of denatured collagen. In conclusion, acetic acid proved to be more effective than citric acid in producing higher yield and superior quality gelatin from yellowfin tuna skin. Further studies should assess the gel strength and amino acid composition of the extracted gelatin.Keywords:environmental chemistrybelow waterbiopolymergelatinmarine chemistrywaste valorizationyellowfin tuna

The spot-tail shark, Carcharhinus sorrah is a species of requiem shark found primarily in warm coastal waters of the Indo-Pacific region. This study aims to assess the length at first maturity and length distribution The spot-tail shark, C. sorrah collected from key fish landing sites in Aceh Province, Indonesia. Data collection occurred between March 2020 and October 2022 at three fishing ports: Banda Aceh (BA), Aceh Barat (AB), and Aceh Barat Daya (ABD). A One-way Analysis of Variance (ANOVA) was employed to analyze the total length (TL) of male and female fish from these sites. Results indicated an overall sex ratio of female to male fish at 1:1.67 (χ² = 45.19, p 0.001), with significant differences observed in sex ratios between BA and ABD (χ² = 6.72, p = 0.01; χ² = 41.14, p 0.001), while AB showed no significant difference (χ² = 1.64, p = 0.20). Logistic regression analysis revealed variations in the length at which 50% of males and females reached maturity (Lm50): males from ABD, AB, and BA were 110.65 cm TL, 117.03 cm TL, and 152.65 cm TL, respectively, while females from BA, ABD, and AB were 107.30 cm TL, 113.94 cm TL, and 116.14 cm TL, respectively. Notably, males from ABD and females from BA matured earlier than those from other sites. In terms of length distribution, the average greatest with standard deviation (±SD) length of male C. sorrah was 122.87±37.87 cm TL in AB, followed by BA at 113.80±13.10 cm TL and ABD at 107.86±18.38 cm TL. This species is important for both ecological balance and fisheries, emphasizing the need for effective management and conservation efforts.Keywords:The spot-tail sharkCarcharhinus sorrahsex ratiolength at first maturitywesternmost Indonesia

‘From the river to the sea’: The weaponization of the concept of anti-Semitism in Vox’s discourse
Authors: Aliberti Davide
Published: January 2025

This article examines how Vox weaponizes the term ‘anti-Semitism’ in its political discourse to undermine the credibility of the left in Spain. Using a critical discourse analysis approach, the research explores Vox’s strategies across five parliamentary debates and five articles published by La Gaceta de la Iberosfera between October 2023 and July 2024. The findings reveal that Vox portrays the left as aligned with Islamist terrorism by leveraging events like Spain’s recognition of Palestine and leftist endorsements of phrases such as ‘From the river to the sea’. This tactic allows Vox to deflect accusations of anti-Semitism and instead attribute them to the left. Through this process, Vox redefines and destabilizes traditional meanings of anti-Semitism, using the term as a rhetorical tool to enhance its own image while discrediting opponents.
