Organ Donation Conversations on X and Development of the OrgReach Social Media Marketing Strategy: Social Network Analysis
Authors: Ahmed Wasim , Hardey Mariann , Vidal-Alaball Josep
Published: January 2025

Background

The digital landscape has become a vital platform for public health discourse, particularly concerning important topics like organ donation. With a global rise in organ transplant needs, fostering public understanding and positive attitudes toward organ donation is critical. Social media platforms, such as X, contain conversations from the public, and key stakeholders maintain an active presence on the platform.

Objective

The goal is to develop insights into organ donation discussions on a popular social media platform (X) and understand the context in which users discussed organ donation advocacy. We investigate the influence of prominent profiles on X and meta-level accounts, including those seeking health information. We use credibility theory to explore the construction and impact of credibility within social media contexts in organ donation discussions.

Methods

Data were retrieved from X between October 2023 and May 2024, covering a 7-month period. The study was able to retrieve a dataset with 20,124 unique users and 33,830 posts. The posts were analyzed using social network analysis and qualitative thematic analysis. NodeXL Pro was used to retrieve and analyze the data, and a network visualization was created by drawing upon the Clauset-Newman-Moore cluster algorithm and the Harel-Koren Fast Multiscale layout algorithm.

Results

This analysis reveals an “elite tier” shaping the conversation, with themes reflecting existing societal sensitivities around organ donation. We demonstrate how prominent social media profiles act as information intermediaries, navigating the tension between open dialogue and negative perceptions. We use our findings, social credibility theory, and review of existing literature to develop the OrgReach Social Media Marketing Strategy for Organ Donation Awareness. The OrgReach strategy developed is based on 5 C’s (Create, Connect, Collaborate, Correct, and Curate), 2 A’s (Access and Analyse), and 3 R’s (Recognize, Respond, and Reevaluate).

Conclusions

The study highlights the crucial role of analyzing social media data by drawing upon social networks and topic analysis to understand influence and network communication patterns. By doing so, the study proposes the OrgReach strategy that can feed into the marketing strategies for organ donation outreach and awareness.

Published: January 2025

Background

Home spirometers have been widely implemented in the treatment of people with cystic fibrosis (CF). Frequent spirometry measurements at home could lead to earlier detection of exacerbations. However, previous research indicates that the long-term use of home spirometry is not well maintained by people with CF.

Objective

We aimed to gain insight into the long-term uptake of home spirometry in regular multicenter CF care.

Methods

Home spirometers combined with a remote monitoring platform were introduced in the treatment of people with CF in 5 Dutch CF centers starting in April 2020. Usage data from April 2020 to December 2022 were analyzed retrospectively. Survival analyses were conducted to assess use consistency over time, and t tests were used to evaluate the impact of increased pulmonary symptoms on home spirometry frequency. The effect of the initiation of a new treatment, Elexacaftor/Tezacaftor/Ivacaftor, on use frequency over time was assessed in a subgroup of participants with repeated measures ANOVA.

Results

During the observation period, a total of 604 people with CF were enrolled in the remote monitoring platform and 9930 home spirometry measurements were performed. After the initiation of home spirometry use, the number of users declined rapidly. One year after the initiation, 232 (54.2%) people with CF stopped using home spirometry. During the observation period, 67 (11.1%) users performed more than 20 measurements. Furthermore, the number of consistent home spirometry users decreased over time. After 600 days, only 1% of users had measured their lung function consistently every 31 days. Use frequency slightly increased during periods with increased pulmonary symptoms (ΔMean=0.45, t497.278=–4,197; P<.001) and showed an initial rise followed by a decrease after starting treatment with Elexacaftor/Tezacaftor/Ivacaftor (ΔMean=0.45, t497.278=–4,197; P<.001).

Conclusions

Consistent uptake of home spirometry in people with CF is low but increases around periods of changing symptoms. A clear strategy for the organization of remote care seemed to improve the long-term uptake of home spirometry. Nevertheless, home spirometry and its intensity are not a goal on their own but should be used as a tool to reach individual goals within local contexts.

Authors: Wang Chi-Hung , Chen Wei-Ren , Yen Jun-Jie
Published: January 2025

BACKGROUND

Brain or central nervous system injuries often lead to impaired walking ability, and traditional ankle-foot orthosis (AFO) can improve gait but is cumbersome to produce and difficult to meet individual needs. In recent years, 3D printing technology has shown potential for assistive device manufacturing due to its high efficiency and accuracy, but clinical research in AFO is still limited.

OBJECTIVE

Individualized AFO was created using 3D scanning and printing technology, and a nine-week training program was used to test its effect on improving stroke patients' walking speed, balance, and gait.

METHODS

This study, 20 stroke patients were recruited to wear 3D AFO to test lower limb function, walking speed, and balance. Methods include the "Walking Speed Test (GST)", "Borg Balance Scale (BBS)" and "Stand Up Walking Test (TUG)" to measure the clinical effect of patients wearing AFO.

RESULTS

Patients wearing 3D AFO walked significantly faster and performed better than those with conventional AFO versus those without AFO. Statistical analysis showed that the improvement in the withdrawal period reached a significant level (Z = 2.64, p < 0.01) and the observer confidence of the Borg balance scale reached 90.45%. Besides, the gait cycle was shortened to 9.8 seconds, and the walking speed was increased to 0.79 m/s, which effectively enhanced the patient's gait stability and walking ability.

CONCLUSIONS

The experimental results showed that 3D AFO could effectively improve the walking speed and gait compensation of stroke patients. In the future, the influence of long-distance testing and the friction coefficient between different materials and the ground on adaptability can be discussed.

Authors: ILLAHI ADHA DASTU , HERTONO GATOT FATWANTO , YANUAR ARRY
Published: January 2025

Objective: This study aims to identify optimal predictive models and key molecular fragments by preparing a dataset and using machine learning techniques within the Konstanz Information Miner (KNIME) platform.
Methods: The human Sodium-glucose Cotransporter 2 (SGLT2) target dataset was obtained from the ChEMBL database and refined by removing salts, incomplete/incorrect data, and duplicates. The data was classified into active and inactive compounds, and fingerprints and descriptors were calculated. Christian Borgelt's Molecular Substructure Miner (MoSS) was employed to identify frequent molecular fragments. Following data partitioning, various ‘classification’ and ‘regression’ machine learning (ML) based Quantitative Structure-Activity Relationship (QSAR) models were developed and evaluated using different techniques, including sensitivity and Mean Squared Error (MSE).
Results: In QSAR classification, the Support Vector Machine (SVM) model demonstrated the best performance with an accuracy of 81.66%, while in QSAR Regression, the Extreme Gradient Boosting (XGB) model exhibited the best coefficient of determination (R2) and Mean Absolute Error (MAE) values of 0.69 and 0.47 respectively. The identification of frequent Molecular Fragments highlighted common characteristics in active SGLT2 inhibitors.
Conclusion: The results of developing these QSAR models indicate that machine learning methods can be effectively used to predict SGLT2 inhibitors virtually, thereby expediting the drug discovery process.

Published: January 2025

Objective: The current study aimed at characterising relevant physical and chemical properties of antimalarial aqueous extracts from the leaves of Artemisia annua (Aa), Vernonia amygdalina (Va), and Microglossa pyrifolia (Mp) to build a solid foundation for the development of stable dosage forms.
Methods: The aqueous extracts were profiled for key antimalarial chemical markers, aqueous solubility, partition coefficient, permeability, and powder flow properties using standard procedure with modifications where applicable. The powder compaction behaviours were studied using Kawakita and tablet ability models.
Results: Aa extract had 11.2 % of total flavonoids and 0.27 % of artemisinin as its antimalarial chemical markers. Va and Mp extracts contained 0.07 % and 28.5 % total terpenoids as their respective chemical markers. All the extracts exhibited high solubility and low permeability, qualifying them as class III crude drugs based on the biopharmaceutical classification system (BCS). Mp had excellent flow (angle of repose 18.9, Hausner Ratio 1.2, and Carr’s Index 13 %) while Va and Aa had passable flow, thus requiring a glidant. The powder samples underwent plastic deformation, according to the Kawakita plot. Aa also showed the highest level of tabletability, followed by Va, and lastly, Mp (Area under curves of 18.5, 9.2, and 7.8 for Aa, Va and Mp, respectively).
Conclusion: Based on their chemical and physical properties, the Aa, Va, and Mp aqueous extracts can be incorporated into stable, bioavailable, and modern herbal drug delivery systems or dosage forms.

Published: January 2025

Objective: This study aims to develop Acyclovir-Loaded Solid Lipid Nanoparticles (ASLN) prepared through homogenisation and evaluate their efficacy.
Methods: ASLN were formulated using Gelucire 43/01, Polyvinylpyrrolidone (PVP), Tween 80, and Stearic acid in varying ratios through solvent evaporation and homogenisation. Lipids and Acyclovir were melted together and then emulsified using a homogeniser. Particle size distribution was assessed by Dynamic Light Scattering (DLS), and Zeta Potential was measured using electrophoretic mobility. The cumulative drug release profile was analyzed to determine sustained release characteristics. Zero-order kinetic modelling was applied to elucidate the release mechanism, indicating diffusion rate-limited drug release. Comparative studies with marketed Acyclovir formulations were conducted to assess efficacy and performance.
Results: All formulations exhibited satisfactory characteristics: Particle size of 185.6±4.28 nm, Zeta potential of-24.15±5.43 mV, Polydispersity Index of 0.192±3.11, and Drug Entrapment Efficiency of 77.06±4.3%. In vitro release studies of ASLN formulation F12 showed prolonged drug release (90.88% cumulative release by the 8th hour), in sustained drug availability. Comparative studies highlighted the efficacy of ASLN compared to commercial acyclovir products. The kinetic analysis confirmed zero-order kinetics and diffusion rate-limited drug release for all formulations.
Conclusion: In conclusion, the formulation of ASLN using Gelucire 43/01, Polyvinylpyrrolidone (PVP), Tween 80, and Stearic acid produced nanoparticles with favourable characteristics. These included appropriate particle size, zeta potential, and high drug entrapment efficiency. In vitro studies demonstrated sustained drug release, suggesting ASLN as promising carriers for enhancing Acyclovir's therapeutic efficacy.

Authors: NAYAK KAVANA KRISHNA , VERMA RUCHI , KUMAR LALIT
Published: January 2025

Prostate cancer is one of the leading causes of male death globally, and its overall incidence flaunts a rising trend over the years. Currently available treatment modalities for prostate cancer suffer from severe toxicity, unpredictable efficacy, high costs, and the emergence of resistance towards anti-cancer compounds. This substantiates the need to develop novel and potent anti-proliferative agents against prostate cancer. Multiple cellular mechanisms underlie the development of prostate cancer and, thus, multiple drug gable targets. In recent years, researchers have been conducting a myriad of investigations in this direction. This work recapitulates the synthesis of 78 such molecules based on recent references. These compounds are classified and tabulated according to the moiety that they possess. Further, the review study highlights the potent member of each chemical class. In addition, the review provides fundamental insights into the design and development of such compounds through the structure-activity relationship of each series of compounds, thereby unlocking new doors for future exploration.

Published: January 2025

In this paper, a novel phase-locked loop is presented based on a repetitive ripple estimator filter. The primary application of the presented phase-locked loop is in the monitoring of three-phase grid voltages and synchronization of grid connected power converters for renewable energy sources with the grid. The filter is inserted inside the loop filter of the phase-locked loop to reject oscillations that can be expected from common grid voltage disturbances. Details of the filter and phase-locked loop are presented, along with the influence of all freely adjustable parameters on overall system behaviour. In the end, the behaviour of the novel phase-locked loop is tested, validated and compared to the base phase-locked loop.
Diagnose eyes diseases using deep learning algorithms
Authors: Abed Z. N. , Al-Bakry A. M.
Published: January 2025

Early diagnosis of eye illnesses is the only way to avoid blindness and to guarantee prompt treatment. A crucial part of early eye disease screening is using fundus images. However, as deep learning (DL) offers a precise classification for medical images, using these methods for fundus images makes sense. Recently, DL architectures were applied extensively to image recognition applications. In the presented study, we use DL models, like Convolutional Neural Networks (CNNs), to identify eye diseases in humans. Due to the development of DL methods, investigations on the detection of eye diseases have produced some fascinating results; nevertheless, most of them are restricted to a particular disease. Ocular Disease Intelligent Recognition dataset is used to assess the suggested approach. This has five thousand images representing eight distinct fundus classes. Those classes correspond to various eye diseases. This work will provide an illustration of the five-step recommended system for diagnosing eye problems. The first step of the model is to collect data sets. The second step is to divide the data sets into 70% for training and 30% for testing. The third step is pre-processing to enhance prediction (converting color images into gray-scale, Histogram Equalization, BLUR and resizing process). The fourth step is to use a variety of the feature extraction algorithms (SIFT and GLCM algorithms) are performed to remove redundant information and extract features from the original data, where features are extracted before they are fed into the classifier for the purpose of accelerating the classification process. In the fourth phase, this study created a CNN-based diagnostic system. Next, it features a model for the prediction of presence or absence of diseases in the patient. The findings demonstrated that the classifiers reached highest accuracy of 99.9%. In addition, we see that our best-performing model outperforms several state-of-art techniques in producing competitive outcomes.

A recuperação de fósforo presente no esgoto através da precipitação química foi abordada nesse estudo. O objetivo foi avaliar as tendências das pesquisas e as correlações das redes acadêmicas relacionadas ao uso da escória de aço como fonte alternativa de Ca e Mg na remoção de fósforo do esgoto. Mapeou-se as publicações entre os anos de 2017 e 2022 através da interface Biblioshiny que é uma ferramenta do bibliometrix. Dentre os resultados encontrados do panorama das publicações, foi identificado que a China é o país que mais publicou durante esse período e observou-se que ocorreu um aumento gradual do número das publicações com o passar destes anos. Dentre as lacunas identificadas, destacam-se a falta de estudos cristalográficos dos precipitados com abordagem das propriedades das estruturas cristalinas formadas nos sistemas, assim como, a utilização de escória com granulometrias maiores que 20 mm nos filtros reativos e sistemas com períodos de operações superiores a 1 ano.

Authors: Mattos Flavio Vassallo , Calmon João Luiz , Ramalho José Carlos Martins
Published: January 2025

There is a growing interest in measuring and evaluating social aspects, such as the impact of actions, activities or decisions on society and the environment. To measure these impacts, a tool called Social Life Cycle Analysis (SLCA) can be used with different types of data or inventory sources. However, the conducted bibliographic review revealed that the quality of the data was not verified in previous SLCA studies of waste pickers associations. Therefore, this study compares the results of an SLCA using the same assessment method but with primary and secondary data, motivating the analysis of relationships between data types and assessment results. This analysis focused on the social impacts on Waste Pickers Organizations located in Vitória, the capital of Espírito Santo, Brazil. The results show better impact levels in the indicators and subcategories when using secondary data instead of primary data. This shows that using secondary data leads to more uncertainties for a study with a Type I SLCA with performance benchmarks. Regarding data quality, the trend remains the same, with primary data being of better quality than secondary data.

Energy, environmental and financial evaluation of progressive cavity pumps with rotors produced from different materials
Authors: Taparello de Souza Marcelo Angelo , Fontana Walter Andrey , Mendes Moraes Carlos Alberto
Published: January 2025

In industrial applications, pumps traditionally operate for thousands of hours at high pressures, often under severe conditions imposed by abrasive fluids or undergoing chemical attack. However, in tinting dispensers, a progressive cavity pump (PCP) rarely reaches one hundred hours of use, and alternative materials could be explored for its components. An energetic, environmental, and financial assessment was conducted on four distinct materials intended for the rotor of a PCP: chrome-coated steel, PA6, PEEK, and 6082 aluminum alloy. Equipment was built to obtain the characteristic curves of each pump, electrical energy consumption, wear of rotors and stators, and energy efficiency. The rotor machining process was instrumented to measure electrical energy and inputs. The Cleaner Production method was applied, and, finally, the rotors underwent financial evaluation. There was no significant wear on the stator-rotor pairs, the minimum lifetime was not a challenge for the integrity of any of the components, and the polymers studied were not incompatible with the working fluid. Maximum and minimum energy efficiency of the pumps occurred with aluminum alloy and PA6 rotors, respectively, showing a difference of 22.5% in electrical energy consumption. However, the PA6 rotor presented the best energy and environmental efficiency in the manufacturing process, in addition to being the only one capable of dry machining. Financially, all proposed materials registered a significant improvement, particularly highlighting the aluminum alloy and PA6 rotors, which exceeded a 90% cost reduction.

Nuestro objetivo fue realizar un diagnóstico de los residuos sólidos (RS) producidos en un pequeño campus de la Universidad Federal Rural de la Amazonia, ubicado en Capitão Poço, Estado de Pará, región de la Amazonia Oriental. También evaluamos la percepción ambiental de los estudiantes de graduación para apoyar la práctica de herramientas de educación ambiental y fomentar el destino adecuado de los RS. Recolectamos quincenalmente y analizamos la composición de RS de todos los residuos producidos en la institución al final de un día. También evaluamos la percepción ambiental de 198 estudiantes a través de la aplicación de un cuestionario. Los resultados mostraron que el campus produjo un promedio de 431.8 kg mes-1 y 21.59 kg día-1 de RS. La mayor parte tiene potencial reciclable (73.7%), como residuos orgánicos (29%), papel (24%) y plástico (17%). El análisis de los cuestionarios mostró que el 58% de los estudiantes desconocen la política de las 5R y solo el 4% separa los residuos en la fuente en los hogares. Sin embargo, más del 70% apoyaría acciones ambientales en la universidad. Los estudiantes de Ciencias Biológicas tuvieron una percepción más comprometida, debido a la influencia de los componentes curriculares y proyectos desarrollados durante la graduación. La institución tiene potencial para gestionar adecuadamente sus residuos, además de implementar políticas eficientes de gestión de residuos sólidos. La solución puede venir a través de la implementación de un Programa de Gestión de Residuos Sólidos, que incluya acciones educativas.

Published: January 2025

A qualidade da água em reservatórios é uma preocupação crescente para sustentabilidade ambiental, os corpos hídricos desempenham um papel vital no fornecimento de água potável, na agricultura e na manutenção dos ecossistemas aquáticos. Nota-se que a questão hídrica vem se agravando ao longo do tempo, sendo a região semiárida a que apresenta maiores impactos em relação a crise hídrica, porém hoje a preocupação com a disponibilidade é notável em todas as regiões do mundo. A pesquisa avaliou o impacto da sazonalidade na qualidade da água do açude Taquara. Os dados utilizados pertencem a Companhia de Gestão dos Recursos Hídricos (COGERH), do período de 2016 a 2020. Os parâmetros analisados para a caracterização da água do açude foram: pH, oxigênio dissolvido, condutividade elétrica, clorofila “a”, cianobactérias, Escherichia coli, nitrogênio total, fósforo total, cloretos, cor, magnésio, potássio, sódio, sólidos totais e turbidez. Para avaliar a qualidade dos corpos hídricos, aplicou-se análises descritivas juntamente na construção de gráficos box-plot nos períodos sazonais e comparou-se as concentrações das variáveis analisadas com os valores máximos permitidos (VMPs) da Resolução CONAMA nº 357/2005 para águas doces classe 2. As concentrações obtidas, em sua maioria, estão dentro dos limites permitidos pela Resolução do CONAMA. Porém, os parâmetros fósforo total, oxigênio dissolvido, Escherichia coli, clorofila a e cianobactérias não atenderam à legislação. Os resultados sugerem variações sazonais e contaminações antrópicas. Destaca-se a importância de entender a influência das mudanças sazonais e adotar medidas para reduzir a interferência humana, visando a preservação da qualidade e sustentabilidade desse recurso vital.

A água potável e segura é um direito humano imprescindível para todos os segmentos da sociedade. Nesse sentido, o programa de vigilância da qualidade da água para consumo humano (VIGIAGUA) visa promover a saúde coletiva e preventiva da população de forma que se diminuam os agravos de doenças relacionadas à transmissão hídrica, por intermédio da gestão de riscos referentes ao sistema de abastecimento de água. Nesse contexto, o presente trabalho teve por objetivo espacializar e analisar os dados de qualidade da água tratada do município de Belém, situada na região amazônica do Estado do Pará-Brasil, usando a ferramenta de Sistema de Informação Geográfica (SIG). A metodologia foi dividida em três principais etapas: inicialmente, foram consultados os dados do Sistema de Informação de Vigilância de Qualidade da Água (SISAGUA); posteriormente, foi avaliada as metas de atendimento com a cobertura do sistema de abastecimento de água e verificação do cumprimento ao plano de amostragem exigidos pelo VIGIAGUA. Além disso, foram elaborados mapas temáticos comparando os resultados com os padrões de potabilidade exigidos pela legislação vigente. Os resultados para os parâmetros básicos apontaram que a turbidez estava em conformidade com o valor de 5 uT para águas provenientes de captação de águas superficiais e 1 uT para águas subterrâneas, conforme o requerido pela Portaria de n° 888, de 4 de maio de 2021, do Ministério da Saúde (MS). Por outro lado, as variáveis de cloro residual livre, coliformes totais e Escherichia coli apresentaram desempenho “PÉSSIMO” em virtude da alteração da água distribuída à população. Portanto, esse cenário de vulnerabilidade coloca em risco a saúde da população devido à contaminação física, química e microbiológica da água do sistema de abastecimento público do município de Belém, apontando a necessidade de políticas públicas emergenciais para que o padrão de potabilidade seja atendido.

As alterações ambientais causadas pelas ações antrópicas refletem diretamente na mudança da paisagem de uma região e, nesse contexto, o município São Félix do Xingu – PA tem passado por diversas modificações. Este trabalho apresenta um mapeamento da cobertura do solo para conhecer a realidade ambiental do município e verifica a confiabilidade de dados MapBiomas para a implantação do Cadastro Ambiental Rural (CAR) de maneira a colaborar com o controle ambiental. Para a realização da análise multitemporal utilizou-se imagens de intervalos temporais quinquenais desde 1985 a 2020, e para verificar a confiabilidade dos dados de cobertura do solo do MapBiomas fez-se a comparação com a cobertura do solo de pequenas, médias e grandes propriedades rurais declaradas e aprovadas no SICAR/PA por meio da exatidão global e coeficiente Kappa. Os resultados mostraram que houve um percentual bastante expressivo de redução de floresta nativa cedendo espaço ao avanço de atividades agropecuárias até 2010, mas posteriormente esse percentual diminuiu com a aplicação de políticas voltadas a diminuição de supressão ilegal da vegetação. Os resultados da comparação de cobertura do solo mostraram que o MapBiomas reflete melhores respostas para análises em menor escala, isto é, para propriedades rurais superiores a 4 módulos fiscais. Portanto conclui-se que a base de dados MapBiomas é pertinente para auxiliar na delimitação da cobertura do solo de médias e grandes propriedades rurais a serem declarados no CAR, sendo uma ferramenta fundamental para ajudar a implementação do CAR.
‘Second Thoughts’: Female Police Officers Trust Themselves Less in Snap Decision-Making
Authors: Paramio Alberto , Tejeiro Ricardo
Published: January 2025

In simulations of snap decision-making under pressure, female police officers performed equally to male officers in terms of decision time, perceived difficulty of the scenarios, and the appropriateness of their behaviour.
However, female police officers exhibited significantly less confidence in their decisions compared to their male counterparts.
These results may reflect the pressures faced by female officers due to stereotypes and the prevailing masculine-conservative police culture.
Deterrent and Motivating Considerations for Entry into the Jamaica Constabulary Force
Authors: Wallace Wendell C.
Published: January 2025

Over the years, motivation for entry into policing has declined due to internal (methods of recruitment) as well as external factors (public perceptions of police).
Motivations for selecting policing as a career in Jamaica include being viewed positively, job stability, personal connections to police officers, providing citizen security and the ability to enforce laws, personal development and self‑improvement, and being an exemplar to others.
Deterrents for entry into the police profession in Jamaica include negative perceptions of the Jamaica Constabulary Force (JCF), the lengthy recruitment process, and perceptions of police corruption in Jamaica.
Motivating factors that influence decisions to enter the JCF can be used as building blocks to attract new recruits, while the deterrent factors can be used to improve the recruitment process and rebrand the image of the JCF so as to make it more attractive to potential police recruits.
Recruiting, Retaining, and Advancing Women in Policing: Lessons Learned From the IAWP Gender-Responsive Policing Summit
Authors: Rief Rachel , Huff Jessica , Clinkinbeard Samantha
Published: January 2025

This brief summarizes themes from the International Association of Women Police GenderResponsive Policing Summit (IAWP), held in collaboration with the Nebraska Association of Women Police. The Summit featured presentations, discussions, and conversations about the status of women in policing. Researchers analyzed notes generated from observations of the Summit.
The Summit served as a critical platform to discuss ongoing challenges women face in policing and explore ways to enhance the workplace for women. Key themes included leadership, driving cultural change, promoting women, persistence and individual agency, health and wellness policies, and affinity groups.
Key themes highlight the need for cultural and structural changes to advance gender equity in policing. Additionally, goal-driven planning and regular assessments are critical for maintaining and advancing progress.
Can a Virtual Reality Training Scenario Elicit a Stress Response Similar to a Realistic ScenarioBased Training Scenario?
Authors: Johncox Jack D. , Martindale M. Hunter , Sandel William L.
Published: January 2025

Virtual reality (VR) technology has evolved over the last couple decades to the point where several law enforcement specific VR training systems are now commercially available. Before this study, it was unclear whether these systems could effectively elicit an acute stress response.
The results of the study in the source article indicate participants exposed to either a virtual reality or in-person scenario had significant and similar increases in acute stress.
While VR has value for training, there are still limitations with the technology that prevent it from taking the place of in-person training for some tasks. Examples include applying aid to injured people, realistic sight alignment for marksmanship, and simulating pain or injuries for participant reinforcement.
Perceptions of Police Treatment from Young Persons with Mental Illness: Findings from the Australian Youth Safety Survey
Authors: Morgan Matthew
Published: January 2025

This study sought to understand the experiences and perceptions of the police from young people with mental illness in Australia.
The findings of the source article showed that young people with mental illness, and other young people with marginalized identities, were significantly more likely than their peers to distrust the police and believe them to be procedurally unjust as an organization.
Public perceptions of the police are important since they may influence the way in which the public and the police interact with one another and whether young people with mental illness will call police for assistance.
The Mock Transcript Technique: An Interviewing Tool for Improving Witnesses Recall
Authors: Chaisson Harper
Published: January 2025

The Mock Transcript technique is designed to help interviewees understand the level of detail expected to be recalled by showing them a lengthy transcribed statement from a “previous interviewee”. The Mock Transcript technique sets a clear expectation for a witness by emphasizing that a prior interviewee put in significant effort and shared extensive fine-grained details when recalling their experience.
Initial laboratory research has shown that the Mock Transcript technique is effective in encouraging interviewees to provide more detailed accounts of what they witnessed. However, more research is needed to determine how well it works during real police interviews.

People are most likely to confess to a crime that they did not commit if they are highly suggestible.
People are somewhat likely to confess to a crime that they did not commit if they are highly compliant.
Suggestive questions should be avoided in police interviews with suspects as they can lead to false confessions and miscarriages of justice.
When Your Words Fail: The (Hidden) Impact of Making Communication Errors in Suspect Interviews and Suicide Negotiations
Authors: Oostinga Miriam S. D.
Published: January 2025

Making communication errors affects law enforcement officers’ thoughts and feelings during suspect interviews and suicide negotiations. Specifically, these errors can lead to more negative emotions such as self-oriented anger, shame, and guilt, as well as stress in suspect interviews, and distraction in suicide negotiations.
Law enforcement officers may use a variety of responses to resolve communication errors, ranging from taking responsibility by apologizing, exploring what is going on, deflecting blame, or providing unrelated comments.
Taking part in the role-playing exercise that was designed for this study, and reviewing the study results, allowed law enforcement officers to safely experience and reflect on the consequences of communication errors. Learning more about how to handle communication errors helps officers to mentally prepare for real-world interactions and enhance their emotional awareness, as well as improve their ability to support colleagues during and after incidents.

Charlotte Puiseux: Teoria Queer e Antivalidismo
Authors: Gonçalves Rocha Renan
Published: January 2025

Resumo
Em De Chair et de Fer: vivre et lutter dans une société validiste, a filósofa Charlotte Puiseux não somente traz uma crítica radical ao modelo sociocultural normativo, ancorado em dinâmicas altamente validistas, mas, também busca pensar as tensões com as normas instituídas sobre os corpos e vidas sociais. Em suas reflexões, ela aporta alternativas teórico-filosóficas e militantes para problematizar o validismo e sua imposição capacitista sobre corpos e formas de existências que transgridem uma noção narcísica, euro-falo-centrada, sobre o que é um corpo. Uma das alternativas propostas por Puiseux é o intercruzamento de teoria queer e teorias antivalidistas. Ela afirma que é necessário “queerizar a deficiência”. A autora questiona a centralidade imposta por uma perspectiva dual e binária, instituída por noções orientadoras do pensamento e de práticas sociais presentes, tanto no discurso sobre corpos, quanto nos espaços destinados a eles. Assim, uma problematização das tipologias conceituais e sociais do normal e do patológico, do corpo válido e inválido, do mito da capacidade e da incapacidade, são pensados pela autora pela perspectiva queer. Para ela, a teoria queer constrói seu estatuto teórico justamente a partir da crítica à naturalização e à biologização de normas socio-historicamente organizadas, reinstituídas, reinventadas e que se impõem como modelo organizacional da vida social. Assim, apresenta-se neste artigo a proposta de Charlotte Puiseux de “queerizar” o debate sobre as deficiências e a interrelação entre teoria queer e teoria antivalidista.
