Influenza and coronavirus disease 2019 (COVID-19) represent two respiratory diseases that have significantly impacted global health, resulting in substantial disease burden and mortality. An optimal solution would be a combined vaccine capable of addressing both diseases, thereby obviating the need for multiple vaccinations. Previously, we conceived a chimeric protein subunit vaccine targeting both influenza virus and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), utilizing the receptor binding domain of spike protein (S-RBD) and the stalk region of hemagglutinin protein (HA-stalk) components. By integrating the S-RBD from the SARS-CoV-2 Delta variant with the headless hemagglutinin (HA) from H1N1 influenza virus, we constructed stable trimeric structures that remain accessible to neutralizing antibodies. This vaccine has demonstrated its potential by conferring protection against a spectrum of strains in mouse models. In this study, we designed an mRNA vaccine candidate encoding the chimeric antigen. The resultant humoral and cellular immune responses were meticulously evaluated in mouse models. Furthermore, the protective efficacy of the vaccine was rigorously examined through challenges with either homologous or heterologous influenza viruses or SARS-CoV-2 strains. Our findings reveal that the mRNA vaccine exhibited robust immunogenicity, engendering high and sustained levels of neutralizing antibodies accompanied by robust and persistent cellular immunity. Notably, this vaccine effectively afforded complete protection to mice against H1N1 or heterosubtypic H5N8 subtypes, as well as the SARS-CoV-2 Delta and Omicron BA.2 variants. Additionally, our mRNA vaccine design can be easily adapted from Delta RBD to Omicron RBD antigens, providing protection against emerging variants. The development of two-in-one vaccine targeting both influenza and COVID-19, incorporating the mRNA platform, may provide a versatile approach to combating future pandemics.
Dressing for disaster: Edo firefighter uniforms and the kabuki tradition
Authors: Hewis Robert
Published: September 2024

In eighteenth- and early nineteenth-century Edo, firefighters were cultural icons in the life of the city. A dense forest of wooden buildings, Japan’s new capital was notorious for its fierce blazes. The hikeshi (‘firefighters’) became instantly recognizable for their striking full-body tattoos and ornately painted jackets, which they would flaunt to the watching crowds after extinguishing a blaze. This unique bodily adornment came to symbolize their manly bravery and the hikeshi were soon popular protagonists in the emerging world of kabuki theatre; multiple ukiyo-e (prints of Edo’s entertainment district) document kabuki actors in their guise. In this article, I illuminate the interactions between the cultural phenomena of Edo – renowned for its print and theatre industries – as they shaped, and were shaped by, the dress and bodies of its firefighters. Through a survey of surviving hikeshi uniforms, I demonstrate visual and material connections between the hikeshi’s ornamented skin, their garments and a series of illustrations by Utagawa Kuniyoshi for the 1827 edition of the epic poem, ‘Water Margin’, about a band of mythically strong bandits. I therefore reframe uniform as an expressive piece of menswear through which the hikeshi participated in an invented masculinity.
‘Behold, it’s new’: Photojournalism and political communication in Zimbabwe
Authors: Tshuma Lungile Augustine
Published: September 2024

Visuals hold a special place in the field of communication. Politicians, in a move to position themselves or market their activities, use visuals that stand as a testimony to their principles. However, their importance and value in political communication are not highly reflected in academic literature. This article is built from this understudied field by looking at the role photojournalists play in framing opposition political parties in Zimbabwe. Photographs are important tools in politics as evidenced by experimental research on political communication that found that ‘a single photograph can have a clear impact on voters’ judgements regarding a candidate’s demeanour, competence, leadership ability, attractiveness, likeableness, and integrity’. This study seeks to analyse photographs that were used by photojournalists to frame the newly formed political party, amidst the power struggles within the party, and political repression from the authoritarian regime. Informed by visual framing, the study found that photojournalists framed Nelson Chamisa as youthful and vibrant while his party was seen as resembling the new dawn. However, photographs also showed that Chamisa and his party had nothing to offer as they did not have a constitution, guiding policy nor a clear ideology.
Rendering the umwelt: Foley, animal life and ethics
Authors: Pollard Damien
Published: September 2024

This article considers the ethical implications of the use of Foley sound in wildlife documentaries. Almost all of the sounds that animals seem to make in these films and television programmes are added by Foley artists; animals in the wild are often filmed using telephoto lenses, beyond the reach of microphones. Crew or vehicle noise will also often muddy sounds recorded on location and so a clean soundtrack must be created in post-production. This article is based on first-hand interviews conducted with practising Foley artists. It details some of the techniques that Foley artists use to simulate the sounds of animals walking, chewing, scratching or otherwise engaging with their environments. It then draws on the work of Emmanuel Levinas to frame ethical activity as the act of encountering the other in terms which recognize and accept their otherness as such. I suggest first that Foley might impede such an ethical encounter with animal life because it seems, at first, to anthropomorphize the animal and to reduce them to a subset of the human. I go on to suggest, however, that Foley is also invested in representing what the biologist Jakob von Uexküll has labelled the umwelt of the animal – the animal’s unique ‘lifeworld’. According to this reading, Foley does ethical work in the wildlife documentary; it brings us to an encounter with the animal’s otherness and intimates that humanity’s own umwelt is but one amongst many. In this way, Foley reveals that the human perception of the world is neither objective nor universal nor absolute. It decentres the human in the way we conceive the world and ethically frames the animal Other as coequal with the human.
Navigating ‘feel’: When hands touch sound effects
Authors: Keenan Fiona
Published: September 2024

Holding and moving objects to create a sound effect requires a performer to navigate by feel, directing their listening from the solid (dried peas on a drumhead) to the imaginary (sea waves). The illusory properties of sound have long been exploited by sound effects performers for the purposes of Foley, silent cinema and theatre. While sound may provoke the imagination or emotional response of the audience, it also does its affective work on the performer operating the effect. In the moment of practice itself, sound binds to the object being manipulated, blurring the known boundaries of its physical properties. The Foley artist crosses a threshold between the tactility of the material and the dissolved representations of the intangible, as the sound itself feels like it is the material being manipulated. Simple hand actions become a gateway to the imaginary. This article considers the affective experience of creative bodily guided soundmaking, and how the successful operation of a sound effect requires the performer to deliberately navigate between modes of listening, attuning their movements and engaging with a perceptual space where things, while making sound, are no longer what they seem to be. Focusing on sound effects beyond the screen allows for an exploration of the aesthetic, dramatic and syncretic in real-world experiences of sound and movement.

Published: September 2024

While it is nationally recognized that there is a high need for teachers, particularly those of diverse backgrounds and with ESL/bilingual certifications, barriers to certification continue to exist for undocumented individuals. Within the state of New Jersey, these barriers mirror the national limitations. Although New Jersey has made efforts to address citizenship and reform policies, some barriers persist, hindering these candidates from making a positive impact on students' lives through a teaching career. This policy piece aims to shed light on the barriers to teacher certification faced by undocumented individuals and outlines measures taken by the Rutgers University-Newark (RU-N) Department of Urban Education to address these challenges.

Authors: Gist Conra D. , Bristol Travis J. , Kulkarni Saili S.
Published: September 2024

This special issue expands upon the Handbook of Research on Teachers of Color and Indigenous Teachers (Gist & Bristol, 2022a) and the practitioner-focused Phi Delta Kappan special issue, “Learning from the Voices of Black, Indigenous and People of Color Educators: Charting New Directions for Research, Policy, and Practice” (Gist & Bristol, 2021). The co-created articles in this special issue highlight the combined expertise of policy makers and education researchers. While the Handbook featured empirical research, and the Phi Delta Kappan special issue featured research briefs and teacher testimonies, the policy-driven articles in this special issue explore how research can be applied at district, state and national levels. A primary goal of this special issue is to provide evidence-based policy recommendations to support policymakers with strategies to address ethnoracial diversity related to one or more of the Handbook’s 11 research domains (i.e., recruitment, program design, mentorship, professional development, retention, pedagogical and leadership practices, induction and human resource development, intersectionalities, educational impact, minority serving institutions, and policy).
Spotlight on Carcinosarcoma of the Ovary: A Scoping Review
Authors: Gauci Martina , Calleja-Agius Jean
Published: September 2024

Ovarian carcinosarcoma, also referred as malignant mixed Mullerian tumour, is an uncommon, highly aggressive and malignant neoplasm which makes up 1 to 4% of all ovarian tumours. It is biphasic involving both malignant sarcomatous (mesenchymal) and carcinomatous (epithelial) cells. There are various subtypes such as serous and endometrioid. However, the mesenchymal part is sarcomatous. About 90% of cases of ovarian carcinosarcoma spread outside the ovary. The two most accepted theories of origin for carcinosarcoma of the ovary are the collision and conversion theories. A third theory is the combination theory. Prognosis remains poor even when still localised in the ovary. In the last few years, there has been no change in the survival rate. The median survival rate is lower than 2 years. Clinical features mainly include lower abdominal pain and a palpable abdominal mass. Ovarian carcinosarcoma remains poorly understood and understudied. Being a rare tumour, elaborate therapeutic consensus is not available for ovarian carcinosarcoma. The main treatment involves cytoreductive surgery and then chemotherapy. The type of chemotherapy, role of radiotherapy and novel therapies need to be further studied. The main objective of this article is to review the current literature on carcinosarcoma of the ovary.
Academic Responsibilities, Obligations, and Freedom: A Call for Review – In Memory of Professor Dr. Tomáš Hudlický
Authors: Sergi Consolato M.
Published: September 2024

The advent and dominance of social media in our daily lives is not a matter of discussion, and very few minimalistic individuals have tried to decrease this technological dependency, which can become toxic and noxious for the development of an autonomous personality and free thinking. Academic faculties claim a depauperation in terms of their freedom but are also not free from duties, responsibilities, and obligations. Here, duties, responsibilities, obligations, and freedom are addressed in historical terms as the university as an institution developed over the centuries after its founding in the 11th century is currently under attack. We premonish that these concepts must still be reiterated and divulgated to students and fellows in academia. Galilei’s “Eppur si muove” (“and yet it moves”) are the words pronounced by the Italian mathematician, physicist, and philosopher Galileo Galilei that should resonate in censorship bodies now and in the future.

The genus Pistacia, with its species having notable ecological, economic, and medicinal implications, demonstrates remarkable environmental adaptability. The central objective of the study is to analyze interspecific variations between Pistacia atlantica subsp. atlantica and Pistacia terebinthus across three distinct bioclimatic zones in the Middle Atlas region of Morocco. The methodology includes collecting dendrometric measurements and conducting macromorphological examinations on these two taxa, with a detailed analysis of 27 qualitative and quantitative variables. A micro-morphological analysis of leaves, using scanning electron microscopy (SEM), is employed to explore specific features such as size and stomatal density, as well as qualitative aspects like epidermal cell shape and trichomes. Dendrometric measurements have revealed that the canopy surface and the number of trunks per tree can serve as distinctive features between the two species. Regarding the sex ratio of Pistacia atlantica subsp. atlantica, 59% of the examined trees are males, primarily associated with the jujube tree in arid zones and the dwarf palm in humid areas. In contrast, female Pistacia terebinthus exhibit a similar percentage, predominantly associated with oak groves and cade juniper in their distribution areas. Principal component analysis of biometric measurements emphasized a significant disparity between the two species, representing 60.25% of the total variance. The use of SEM unveiled new features facilitating the identification of the two species. By leveraging the macromorphological and micromorphological variability of pistachio trees, we can qualify those best suited to diverse bioclimates. In this regard, we suggest incorporating them into reforestation and rehabilitation programs aimed at restoring our declining ecosystems.

Published: September 2024

High-voltage outdoor insulating materials face formidable challenges emanating from stresses such as electrical discharge, humidity, and UV radiation, propelling them perilously toward potential failure. To combat this, researchers explored novel materials to enhance insulator performance under these stresses. In this study, samples infused with micro-/nano-alumina trihydrate (ATH) and -magnesium hydroxide (MH) were tested with a base polymer (RTV-SR – room-temperature vulcanizing silicone rubber) during a 100 h electrical discharge aging process. They were simultaneously exposed to AC discharges, UV irradiation, and varying humidity levels. The study found a decline in hydrophobicity in all samples post-discharge exposure. Notably, composites with micro- and nano-fillers exhibited prolonged hydrophobic recovery under stresses such as medium humidity and UV irradiation. Scanning electron microscopy analysis displayed deep cracks and block-like structures on surfaces, particularly in samples R1 (50% micro-MH) and R2 (50% micro-ATH). Aged sections of R3 (10% nano-ATH) and R4 (10% nano-MH) showed heightened surface cracks compared to R5 and R6. Energy-dispersive X-ray analysis detected surface oxidation, emphasizing the severity of electrical and other stresses. FTIR results indicated minimal absorption peak reduction in co-filled samples after aging. These findings highlight the impact of co-filled composite insulators for robust insulating systems to withstand the hostile outdoor environment.

There is experimental evidence of varying correlation among the elements of the neuromuscular system over the course of the reach-and-grasp task. The aim of this study was to investigate if modifications in correlations and clustering can be detected in the local field potential (LFP) recordings of the motor cortex during the task. To this end, we analyzed the LFP recordings from a previously published study on monkeys that performed a reach-and-grasp task for targets with a vertical or horizontal orientation. LFP signals were recorded from the motor and premotor cortex of macaque monkeys as they performed the task. We found very robust changes in the correlations of the multielectrode LFP recordings that corresponded to task epochs. Mean LFP correlation increased significantly during reach and then decreased during grasp. This pattern was very robust for both left and right arm reaches irrespective of target orientation. A hierarchical cluster analysis also demonstrated similar changes. In focusing on correlations, our study has contributed new insights to the understanding of LFP signals and their relationship to movement. A sliding window computation of the number of clusters was performed to probe the capacities of the LFP clusters for detecting upcoming task events. For a very high percentage of trials (97.89%), there was a downturn in cluster number following the Pellet Drop (GO signal) that reached a minimum preceding the Start of grasp, hence indicating that cluster analyses of LFPs could contribute to signaling an increased probability of the Start of grasp.
Gender Wealth Gap in the USA’s Afrobeats Scene
Authors: Opara Ruth
Published: September 2024

The United States has been a space for global musical transnational encounters among African-descended peoples, with various artists collaborating. These collaborations have blossomed with the advent of Afrobeats—a loose term describing the contemporary transatlantic sound of popular African music. Although there are male and female Afrobeats performers on the African continent, this cultural exchange occurs more often between male artists and U.S. musicians. Because male artists are mostly invited for live performances, their visibility puts them in a position to perform with and collaborate with U.S. artists. As a result, male artists get nominations for global awards such as the Grammys and accumulate more wealth. For female artists, the result is less visibility and wealth. Using Tiwa Savage and Burna Boy—two Afrobeats giants—as case studies, this essay examines the factors that limit Tiwa, a female performer, from achieving the same wealth as her male counterpart, Burna Boy. Specifically, this study analyzes the sonic and semiotic representations in their popular music videos, Tiwa’s “Koroba” and Burna Boy’s “On the Low,” to understand why Burna Boy might have the edge over Tiwa. Their music and career trajectories shed light on how capitalism and sociopolitical issues, including colorism, might contribute to the gender wealth disparities between male and female Afrobeats performers.
Pitchfork, Race, Collaboration, and the Making of “Indie Rap”
Authors: Mangat Ajitpaul
Published: September 2024

This essay historicizes the moment in popular music when rap music and indie rock began conversing with one another. It shows how Pitchfork received, what is referred to as, “indie rap” by drawing a particular line of influence: from indie rock to rap music. Pitchfork is thereby shown to have contributed to the historical whitening of Black music. Drawing on the work of Fred Moten, this essay argues that Pitchfork established the “white avant-gardism” of indie rock through the construction of a series of binary oppositions that associated Black rap music with pastness and the commercial and “white” indie rock with futurity and the experimental. Such a critical bifurcation is revealed through a close reading of Pitchfork’s reception of the artist most representative of “indie rap:” Kanye West. This essay shows how Pitchfork understood West as needing to appropriate “European” music to move from the past into the future and become experimental. It counters this antagonistic racialization by situating West’s use of Auto-Tune within a lineage of Black radical aesthetics that includes the experimental vocal manipulations of artists ranging from Stevie Wonder to Drake. This essay seeks to recover the collaborative spirit that defined “indie rap.” It focuses on West’s collaborations with Justin Vernon (of Bon Iver), showing how they labored together to produce an “indie rap” that crossed the musical and racial lines established by Pitchfork. This essay concludes that, if West epitomized an ethos of collaboration before his reactionary turn, it is Vernon who now carries forward this collaborative spirit.

This autoethnographic study examines powerviolence in the predominantly Hispanic unincorporated area of El Rio, California, from the perspective of a drummer in a local powerviolence band. The unique human geography of El Rio, characterized by its demographic composition, urban layout, and cultural practices, shapes sonic cartographies and influences how individuals understand sound. Situating powerviolence as a form of “borderlands noise-music,” this article investigates the intersection of sound perception and cultural identity, particularly for Chicano noise musicians. By exploring how powerviolence subverts dominant music constructs through its sonic, linguistic, emotional, and iconographic elements, this article highlights the transformative potential of noise-music in marginalized communities. Drawing on a sonic lineage from hardcore punk to powerviolence in California, commonalities among hardcore punk, thrashcore, grindcore, and powerviolence are illuminated, providing a basis for understanding powerviolence through sound. Furthermore, this study foregrounds the significance of powerviolence and noise-music as accessible forms of expression, particularly for aspiring musicians who lack the means to pursue formal study. By amplifying voices that may otherwise go unheard, powerviolence allows noise musicians to feel audible to dominant capitalist society.

Published: September 2024

It was established that during the first year of the war, the aggregate indicator of the efficiency of the functioning of agricultural enterprises decreased by 25.3% - from 18.31 to 13.67. However, the absolute value of this indicator in 2022 exceeds the indicators of 2017, 2018 and 2020. According to groups of indicators, efficiency indicators experienced the greatest decrease - more than 2 times (from 11.49 to 5.13). Economic and production indicators and indicators of the financial condition of agricultural enterprises decreased during the first year of the war by 19.5 and 18.1%, respectively. The integral indicator of financial support of agricultural enterprises showed a positive growth rate of 5.7%, which is explained by an increase in their capital by 7.2% (96.6 billion UAH) thanks to a significant (43.5% or 35.9 billion UAH) growth attraction of bank loans.

Import substitution of elevator equipment in public procurements: problems and directions of stimulation
Authors:   Institute for Economics and Forecasting, NAS of Ukraine, Snigova Olena
Published: September 2024

The problem of import substitution is relevant for any country, taken into account the requirements of its economic self-sufficiency, independence on the situation at the international markets and on geopolitical changes. For Ukraine in the state of full-scale war, this task is important from the viewpoints of economic resilience and security. For this reason, the Government determined the substitution of import components in public procurements as one of the priorities of its activity. Solving this problem will be important for the projects associated with the procurement for the recovery of infrastructure in post-war period. The sector of elevator equipment production has a significant industrial potential for the post-war recovery of infrastructure in Ukraine. Extension of industrial capacity of this segment of machine building in order to cover the domestic market requirements in post-war recovery period will enable new job creation and will provide a multiplicative effect based on the development of complementary suppliers of production components. However, a number of problems prevents Ukrainian elevator equipment producers from winning in public procurements. The goal of the article is to substantiate the reasonability and to determine the directions and stimulating measures for elevator equipment import substitution in public procurements in Ukraine. The market of elevator equipment of Ukraine has been analyzed. The capacity of Ukrainian elevator equipment producers to compete at the domestic market has been assessed based on price, warranty terms, cost of warranty service, and quality of equipment. Public procurement of elevator equipment and maintenance services in “Prozorro” system has been studied. It was found that about 70 % of public procurements of elevator equipment account for the purchases of imported equipment from Turkey and China. The problems of domestic producers of elevator equipment preventing them from winning the public procurement have been explained. The multiplicative effect from the increase of public procurements of elevator equipment from national producers has been assessed. This proves the reasonability to stimulate import substitution of elevator equipment in public procurements. The directions and measures of elevator equipment import substitution stimulation in public procurements in Ukraine have been suggested.
The development of strategic industrial sectors of Ukraine in the context of national economic security: theoretical foundations
Authors:   National academy of internal affairs, Kozachenko Ganna , Pogorelov Yuri ,   Accounting Chamber Ukraine
Published: September 2024

The article demonstrates the need to identify strategic sectors of industry for the social and economic development of the state, which allows focusing the attention and limited resources of the state on supporting the development of those sectors that ensure national economic security. Within the epistemological contextualism, the concept of "strategic sector" is defined. To classify an industry sector as strategic, proposed criteria are outlined based on objective, sustainable circumstances in the country's economy, and within the context of national economic security. The definition of "national economic security" is provided. The criteria for recognizing the strategic nature of an industrial sector within the context of national economic security are determined by operationalizing constructs derived from the proposed definition of a "strategic industrial sector". Quantitative indicators are proposed to quantitatively describe the degree (intensity) of the criterion for recognizing the strategic nature of an industrial sector within the context of national economic security. The development of the strategic sector of the industry in the context of national economic security is ensured by critical enterprises in the industry. To recognize enterprises in strategic industrial sectors as critical for the industry's development in the context of national economic security, a number of criteria have been proposed. The development of critical enterprises in the industry should be security-oriented in nature. Support and regulation of security-oriented development of enterprises in the strategic industrial complex of Ukraine, which are to include recognized strategically important industries based on proposed criteria for national economic security, should be carried out using a comprehensive mechanism of state regulation of the country's strategic industrial complex.

The UIN Jakarta Career Development Center is a dedicated unit focused on fostering the personal and professional growth of both current students and alumni of UIN Jakarta. Supported by student interns from diverse educational backgrounds and academic programs, the center operates daily to provide comprehensive services. These interns bring varied educational backgrounds and experiences, influencing their readiness to implement software for collaborative and coordinating purposes, replacing the previous system (Trello) at the UIN Jakarta Career Development Center. This study aims to evaluate Trello's effectiveness at the UIN Jakarta Career Development Center, intending to enhance the interns' performance and improve service delivery to uphold UIN Jakarta's reputation. The research methodology employs the System Usability Scale (SUS), with validity and reliability testing conducted using Cronbach's Alpha. Findings indicate that Trello's usability at the UIN Jakarta Career Development Center yields an average total score of 59.625 on the grade scale, categorizing usability as D with an adjective rating of OK and marginally acceptable. However, 37.5% respondents express skepticism regarding others' ability to quickly grasp Trello's use, while 55.5% state a need to acclimate themselves to Trello's usage. These insights underscore the importance of refining Trello's implementation to better support the center's operations and ensure a seamless user experience for interns and staff alike.

Predicting repeat buyers is essential for businesses seeking to improve customer retention and maximize profitability. This study examines the effectiveness of logistic regression and random forest algorithms in forecasting repeat buyers, utilizing an e-commerce dataset from Kaggle. Despite the theoretical strengths of these models, our results indicate significant performance challenges. Both models were evaluated on key metrics: accuracy, precision, recall, F1 score, and ROC-AUC. The findings revealed that the models logistic regression and random forest performed poorly, with accuracy hovering around 50%, precision and recall demonstrating imbalanced performance, and ROC-AUC scores barely exceeding random guessing levels. Such metrics highlight the limited discriminative power of these models in identifying repeat buyers. The analysis suggests that issues such as data quality, feature relevance, and class imbalance contribute to these shortcomings. Specifically, the models struggled to effectively learn from the data, leading to suboptimal predictions. These results underscore the need for enhanced feature engineering, better handling of class imbalance, and possibly exploring more advanced algorithms. This study provides a critical assessment of the limitations inherent in using Logistic Regression and Random Forest for predicting repeat buyers, hence implements feature engineering, SMOTE and hyperparameter tuning using RandomSearchCV to get better result.

Published: September 2024

Food security is one of the Indonesian government's priority policies aimed at maintaining economic and political stability. To ensure the nutritional needs of its population are met, the government requires sufficient food availability distributed nationwide at stable and affordable prices. Rice is the main staple food in Indonesia. According to data from the National Food Agency, rice consumption in Indonesia is very high, averaging 139 kilograms per capita per year, with a dependency rate of 97%. In response to food security challenges, the Indonesian government has entrusted the Food Supply and Price Stabilization Program (SPHP) for rice to Perum BULOG, a State-Owned Enterprise (SOE) specializing in food logistics. To optimize distribution to Perum BULOG’s retailers, called Rumah Pangan Kita (RPK), efficient routes and transport capacity are prioritized. Therefore, this paper proposes an approach using the Heterogeneous Capacitated Vehicle Routing Problem (HCVRP) to enhance distribution efficiency and reduce delivery costs. By employing the K-Means algorithm to cluster RPK addresses and Guided Local Search via OR-Tools to determine suitable transportation types, this study successfully identified optimal delivery routes for each cluster and corresponding vehicle types. The results demonstrated a reduction in delivery costs of up to 21%, significantly improving the efficiency of the SPHP rice distribution process. This outcome ultimately supports rice availability and price stability, crucial for maintaining food security in Indonesia.

Background and Aims

This study sought to identify patterns of psychedelic use among American psychiatrists, to compare the demographic variables across categories of social proximity and personal use, and to determine how these categories influenced psychiatrists' attitudes towards drugs and people who use drugs.

Methods

Respondents (N = 180; mean age = 48.4 [SD = 16.2]; male = 65.5%; trainees = 24.1%) were recruited via email lists/listservs and personal networks (snowball sampling).

Results

Approximately one-third (32.8%) of psychiatrists reported Personal Connection (i.e., history of personal use and social connection) to psychedelics. Psychiatrists with Personal Connection to psychedelics were more likely to be younger (p = 0.006, ηp2 = 0.057) and have fewer years of practice (p = 0.008, ηp2 = 0.058). Almost all (92%) of those with No Connection to psychedelics were out of training, compared with only 8% of those in training. Those with Personal and Social Connection to psychedelics were more likely to disagree: that using illegal drugs is morally wrong (p < 0.001, ηp2 = 0.28), that illegal drug users should go to prison (p < 0.001, ηp2 = 0.15), are weak minded (p < 0.001, ηp2 = 0.10), have no future (p < 0.001, ηp2 = 0.12), are not well educated (F(2.0, 170) = 7.38. p < 0.001, ηp2 = 0.08), are dishonest (p < 0.001, ηp2 = 0.10), and that illegal drug users ‘make me angry’ (p < 0.001, ηp2 = 0.10).

Conclusions

Personal and social connection to psychedelics is associated with decreased stigma towards drug use and people who use drugs. Future research should examine whether proximity to psychedelic use impacts other factors (e.g., empathy, therapeutic alliance) involved in psychiatry training and practice.
