BACKGROUND: Successful liberation from mechanical ventilation is one of the most crucial processes in critical care because it is the first step by which a respiratory failure patient begins to transition out of the intensive care unit and return to their own life. Therefore, when devising appropriate strategies for removing mechanical ventilation, it is essential to consider not only the individual experiences of healthcare professionals, but also scientific and systematic approaches. Recently, numerous studies have investigated methods and tools for identifying when mechanically ventilated patients are ready to breathe on their own. The Korean Society of Critical Care Medicine therefore provides these recommendations to clinicians about liberation from the ventilator.
METHODS: Meta-analyses and comprehensive syntheses were used to thoroughly review, compile, and summarize the complete body of relevant evidence. All studies were meticulously assessed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) method, and the outcomes were presented succinctly as evidence profiles. Those evidence syntheses were discussed by a multidisciplinary committee of experts in mechanical ventilation, who then developed and approved recommendations.
RESULTS: Recommendations for nine population, intervention, comparator, outcome (PICO) questions about ventilator liberation are presented in this document. This guideline includes seven conditional recommendations, one expert consensus recommendation, and one conditional deferred recommendation.
CONCLUSIONS: We developed these clinical guidelines for mechanical ventilation liberation to provide meaningful recommendations. These guidelines reflect the best treatment for patients seeking liberation from mechanical ventilation.

Within this article, we utilize intersectionality theory as a framework for understanding the experiences of Black girls who attend PK-12 schools in the United States. Black girls\' experiences are then illuminated within the context of the school racial climate research. We then add an intersectional lens to the school racial climate research to demonstrate how specific aspects of the school environment influence the experiences and perceptions of Black girls and their developmental outcomes. Finally, we conclude with recommendations for helping schools become fair and liberatory spaces that honor the full humanity of Black girls, their current schooling experiences, and their visions for their future selves.

BACKGROUND: Four Black early-career faculty members, one Black doctoral student, and a Black senior faculty member, (herein referred to as scholars), previously engaged in cross-cultural mentoring with a White senior researcher to bolster their scholarship.
OBJECTIVE: In the years following the 2020 racial reckoning, the scholars were motivated to reconvene by the realization that traditional scholarship activities of academia ignore historical educational oppression and fail to account for the contemporary effects of racism and discrimination rooted in American colonialism.
METHODS: Collaborative autoethnography, a decolonizing qualitative approach to research, was used to explicate our journeys in academia. The tenets of Freire\'s critical pedagogy (conscientização, scholarship, praxis) framed our collective experiences.
CONCLUSIONS: We describe resisting academic structures of power, discrimination, and disadvantage through reformation, crafting a vision statement, and utilizing positions of influence.
CONCLUSIONS: To decolonize nursing academia, we implore the scholarly community to pursue liberation and contest structures that center Whiteness and marginalize collectivism and collaboration.

The purpose of this article is to delineate the nature of the colonial mindset, which perpetuates gendered settler colonial structures of historical oppression in research and practice. By connecting a critical consciousness and living in alignment with agility (AWA), this work explicates pathways from gendered complicity to embodying praxis-or becoming gender AWAke. This article begins by describing the nature of the colonial mindset. Second, I critically examine the dominant discourse institutionalized by Western psychology. Third, I introduce the FHORT and critically analyze how the colonial mindset has affected and driven violence against Indigenous women. Examining how settler colonial structural sexism in its heteropatriarchal and heteropaternalistic forms has become imposed upon the lives of Indigenous women and gender-expansive peoples exposes subjugated knowledges; it provides an empirical scaffolding for people to become critically conscious of dominant gender norms that apply to people, institutions, and society more broadly. Finally, I propose living AWAke for personal and collective liberation.

The increasing global market size of high-energy storage devices due to the boom in electric vehicles and portable electronics has caused the battery industry to produce a lot of waste lithium-ion batteries. The liberation and de-agglomeration of cathode material are the necessary procedures to improve the recycling derived from spent lithium-ion batteries, as well as enabling the direct recycling pathway. In this study, the supercritical (SC) CO2 was innovatively adapted to enable the recycling of spent lithium-ion batteries (LIBs) based on facilitating the interaction with a binder and dimethyl sulfoxide (DMSO) co-solvent. The results show that the optimum experimental conditions to liberate the cathode particles are processing at a temperature of 70 °C and 80 bar pressure for a duration of 20 min. During the treatment, polyvinylidene fluoride (PVDF) was dissolved in the SC fluid system and collected in the dimethyl sulfoxide (DMSO), as detected by the Fourier Transform Infrared Spectrometer (FTIR). The liberation yield of the cathode from the current collector reaches 96.7% under optimal conditions and thus, the cathode particles are dispersed into smaller fragments. Afterwards, PVDF can be precipitated and reused. In addition, there is no hydrogen fluoride (HF) gas emission due to binder decomposition in the suggested process. The proposed SC-CO2 and co-solvent system effectively separate the PVDF from Li-ion battery electrodes. Thus, this approach is promising as an alternative pre-treatment method due to its efficiency, relatively low energy consumption, and environmental benign features.

COVID-19 elicited a rapid emergence of new mutual aid networks in the US, but the practices of these networks are understudied. Using qualitative methods, we explored the empirical ethics guiding US-based mutual aid networks\' activities, and assessed the alignment between principles and practices as networks mobilized to meet community needs during 2020-21. We conducted in-depth interviews with 15 mutual aid group organizers and supplemented these with secondary source materials on mutual aid activities and participant observation of mutual aid organizing efforts. We analyzed participants\' practices in relation to key mutual aid principles as defined in the literature: 1) solidarity not charity; 2) non-hierarchical organizational structures; 3) equity in decision-making; and 4) political engagement. Our data also yielded a fifth principle, \"mutuality,\" essential to networks\' approaches but distinct from anarchist conceptions of mutualism. While mutual aid networks were heavily invested in these ethical principles, they struggled to achieve them in practice. These findings underscore the importance of mutual aid praxis as an intersection between ethical principles and practices, and the challenges that contemporary, and often new, mutual aid networks responding to COVID-19 face in developing praxis during a period of prolonged crisis. We develop a theory-of-change model that illuminates both the opportunities and the potential pitfalls of mutual aid work in the context of structural inequities, and shows how communities can achieve justice-oriented mutual aid praxis in current and future crises.

Despite prior publications of clinical practice guidelines related to ventilator liberation, some questions remain unanswered. Many of these questions relate to the details of bedside implementation. We, therefore, formed a guidelines committee of individuals with experience and knowledge of ventilator liberation as well as a medical librarian. Using Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology, we make the following recommendations: (1) We suggest that calculation of a rapid shallow breathing index is not needed to determine readiness for a spontaneous breathing trial (SBT) (conditional recommendation; moderate certainty); (2) We suggest that SBTs can be conducted with or without pressure support ventilation (conditional recommendation, moderate certainty); (3) We suggest a standardized approach to assessment and, if appropriate, completion of an SBT before noon each day (conditional recommendation, very low certainty); and (4) We suggest that FIO2 should not be increased during an SBT (conditional recommendation, very low certainty). These recommendations are intended to assist bedside clinicians to liberate adult critically ill patients more rapidly from mechanical ventilation.

Prejudice against LGBTQ people during their schooling years can be detrimental due to its long-term consequences. This includes the development of beliefs that the world is unsafe, which can perpetuate mental health struggles later in life. Fostering a school environment where LGBTQ people can express their identity can contribute to greater well-being. This qualitative study drew on interviews with 13 school graduates to examine the environmental factors within Australian schools that influenced LGBTQ students\' expression of their identity. Drawing on Altman\'s conceptualization of oppression and liberation, this study found students typically experienced liberation in the form of acceptance and validation within their micro-environment at school. This micro-environment was composed of those close to the student, such as friends, allies, teachers, and other LGBTQ students who provided acceptance and validation, which enabled the student to express their identity regardless of oppression within the broader school environment. Oppression on the other hand originated from the invisibility of LGBTQ identities; the limited representation in curriculum and access to LGBTQ-specific resources and supports; concerns around gendered, gender-neutral, and safe spaces; and limited support from teachers. Based on the findings, implications are drawn to enhance both the micro and macro environment for LGBTQ school students.

When it comes to the piano, the term \"action\" describes the mechanism that causes hammers to strike the strings when a key is pressed. Every piano has its own action; it\'s what gives the instrument a unique voice and sonic impact. My grandmother, a self-taught musician, born at the height of the Great Depression in a Jim Crow south, relentlessly harnessed her hope and heart in every note. Although she is no longer with us on this side of the heavens she prayed to, her ability to transgress, to disrupt, to agitate, to express joy through music, transcends the ethereal boundary between life and death. This poem is emblematic of the voice and sonic impact of Black women, who, when pressed like those ivory keys, emit a song of liberation; a set of instructions for symbolic remembrance, (re)centering joy as an act of resistance. Such an action is an antecedent to healing that which has been broken within the self, and the systems that particular self inhabits.To view the original version of this poem, see the supplemental material section of this article online.

Latinx have contributed to the foundation and formation of the United States, and as this demographic increases, overlooking their unique experiences and lived conditions can limit community psychology\'s potential to better support them in their wellbeing. Thus, in alignment with the call for a virtual special issue highlighting critical themes in the American Journal of Community Psychology (AJCP), we take an exemplar approach to reviewing 15 articles published between 1979 and 2023. We highlight these articles for their unique contributions in laying the foundation or shifting the discourses of Latinx in the United States. We organize each article under one of the following themes: (1) Challenging notions of Latinx as passive victims or deficient; (2) Documenting the misrepresentation and invisibility of Latinx in community psychology; (3) Affirming Latinx as knowledge producers, protagonists, and agents of change; and (4) Centering Latin American epistemologies that foster liberatory praxis for and with Latinx. Via these themes, we illustrate where the discipline has been, and offer reflection for where it can move toward as it relates to Latinx. In doing so, we highlight perspectives grounded in Latinx communities. Our review is not exhaustive; however, it offers our subjective interpretation or curation of the articles we acknowledge as fundamental to the discipline\'s formation, and our learning and ongoing growth as critical community psychologists of Latin American heritage with affinities to Latinx communities in the United States. We offer this brief review as a semilla (seed) to the possibilities ahead as we remain open to reflection, dialog and learning.
