Public awareness of mental illness: Mental health literacy or concept creep?

Rising awareness of mental illness has increased the public's mental health literacy, with positive implications for help-seeking and destigmatization. We argue that it has also enlarged the public's concept of mental illness. People have become better at recognizing the presence of mental illness but may have become worse at recognizing its absence. This conceptual expansion fosters unwarranted self-diagnosis, the pathologization of ordinary distress, and unnecessary treatment. It is incumbent on mental health professionals to promote accurate knowledge of mental illness and push back against overly expansive concepts of it.

Integration of Local Wisdom of Natural Color Sasirangan in Project-based Learning with STEAM Approach to train Science Literacy

<span lang="EN-US">Science learning should provide meaningful experiences for students to understand various scientific phenomena in life. Integrating local wisdom in learning can improve scientific literacy because the various concepts learned are witnessed directly by students in life. This research uses theoretical studies to describe the integration of local wisdom of natural color sasirangan in project-based learning with the STEAM approach to improve science literacy.</span><span lang="EN-US"> The STEAM approach is in the form of a) science in the form of the phenomenon of abundant dye water from the pot due to expansion; b) technology in the form of sasirangan fabric dyeing machines; c) engineering in the form of manipulation of the use of natural dyes and fixation; d) art in the form of making sasirangan cloth motifs; e) Mathematics in the form of temperature measurement using a thermometer and heat to increase the temperature of the dye liquid. The stage of making sasirangan cloth consists of making patterns, jalujur, sisit, dye, dedel, washing and ironing. The concept of temperature and heat found in the process of making natural color sasirangan includes; a) the concept of temperature when cooked water slowly becomes hot; b) the concept of expansion on the phenomenon of natural dye water spilling from the pot when cooked; c) the concept of heat is seen in water that has a large mass requires more heat to achieve a certain temperature increase; d) The concept of radiant heat transfer can be proven when the sasirangan cloth is dried in the sun</span>

Humanizing Different Archetypal Expressions of Gender Expansiveness1.

This article explores the concept of gender expansiveness. This term refers to a person's self-identifying as gender fluid, genderqueer, transgender, non-binary, gender diverse, or gender nonconforming. Young people, including older children and adolescents, increasingly are experimenting with crossing gender lines. This trend can be understood as a sociocultural process for humanizing more terrifying archetypal forms of gender diversity. Using Henderson's (1988) concept of the cultural unconscious, the author posits that current social developments among youth are attempting to bring gender expansiveness more into collective consciousness. This issue has occasioned a strong counterreaction with panicked appeals to upholding traditional gender norms and needing restrictions on gender-affirming care. Examples from myth, literature and clinical practice help to contextualize the intense emotions aroused by gender diversity. A case example shows how gender fantasies are worked through within an empathic analytic relationship. The author makes an appeal for updating and humanizing older psychological theories that have relied heavily on splits, polarities, and oppositions, all of which are more characteristic of a 20th century way of thinking about the psyche. A potential approach to incorporate gender expansiveness is through a model of the psyche as a mosaic.

Scalp-Split Technique: A Concept of Bone Splitting and Expansion for Thin Alveolar Ridges to Place Dental Implants.

Bone expansion is when the existing bone at the implant site is split and separated to create a gap to widen it. This article introduces a novel concept of bone expansion for the ultrathin alveolar ridges to place dental implants with zero wastage of existing natural bone in long-term edentulous arches. Instead of using twist drills and piezo surgery kits, the bone is split with a surgical scalpel blade to prevent natural bone wastage. The split helps to expand the bone horizontally by using expanders to accommodate the smaller diameter implants. This technique was applied to 12 individuals to rehabilitate their atrophic edentulous mandibles to facilitate the implant-supported overdentures, and it revealed that all the cases achieved successful osseointegration after placing implants following this method. The scalp-spilt technique is promising for providing implant-retained or implant-supported prostheses over ultrathin edentulous alveolar ridges.

Effects of diagnostic labels on perceptions of marginal cases of mental ill-health

Two experimental studies (Ns = 261, 684) investigated how diagnostic labels affect perceptions of people experiencing marginal levels of mental ill-health. These effects offer insight into the consequences of diagnostic “concept creep”, in which concepts of mental illness broaden to include less severe phenomena. The studies found consistent evidence that diagnostic labeling increases the perception that people experiencing marginal problems require professional treatment, and some evidence that it increases empathy towards them and support for affording them special allowances at work, school, and home. The studies also indicated that labels may reduce the control people are perceived to have over their problems and their likelihood of recovering from them. These findings point to the potential mixed blessings of broad diagnostic concepts and the cultural trends responsible for them. Expansive concepts may promote help-seeking, empathy, and support, but also undermine perceived agency and expectations that problems can be overcome.

Ecological Crises and Ecopolitics Research in Australia

It is difficult to exaggerate the scale of contemporary ecological crises. These challenges, particularly climate change, necessitate new modes of politics and policy, even potentially new institutions, that seem anathema to the emphases of traditional accounts of environmental political science. In this paper, we explore contemporary ecopolitics research in Australia that is attempting to come to terms with the reality of ecological crises and the geological epoch of the Anthropocene. Showcasing a range of scholarship in this area, we argue that contemporary Australian ecopolitics research identifies and engages with a wide range of sites of politics and a significant number of (consequential) political actors. It recognises the need to engage directly with key institutions while also extending our gaze to the environment movement, community groups, financial institutions, local governments, and consumers. It acknowledges that sites of politics extend from the way ecological crises are framed in public debate to policy management, practices of private corporations and even to individual patterns of consumption. And it argues for an expansive conception of ethics beyond currently living human communities, a vision which arguably better meets the reality of ecological crises and the Anthropocene epoch.

Progressive Originalism and the New Canon Wars

Abstract This essay responds to Geoffrey Kirsch’s review essay “What’s Past is Prologue: Democracy in the Age of Originalism” by evaluating how the three texts Kirsch reviews—Kermit Roosevelt, III’s The Nation That Never Was: Reconstructing America’s Story (2022), Cass R. Sunstein’s How to Interpret the Constitution (2023), and D. Berton Emerson and Gregory Laski’s edited collection Democracies in America: Keywords for the Nineteenth Century and Today (2023)—engage with progressive originalism. Drawing inspiration from civil rights activists including Frederick Douglass, progressive originalists seek to recast an ostensibly conservative method of constitutional interpretation grounded in what the “founding fathers” or a historical public thought or intended. Roosevelt’s and Sunstein’s books reveal the potential and limits of both progressive originalism and insular disciplinary conversations about constitutional interpretation. Contrastingly, the multidisciplinary Democracies in America has a more expansive conception of whose voices should matter when interpreting the Constitution through a progressive originalist lens. A comparative analysis of the three books also demonstrates the value of literature and literary historians in an age characterized by the ascendancy of historical approaches to constitutional interpretation and a revival of the “canon wars.”

Interactive Demonstration Learning to Improve Conceptual Understanding of Class VII Students Materials: Temperature, Heat, and Expansion

Science education is a great opportunity to create a generation of people with character. In classroom learning, there are several obstacles so that students do not optimally accept concepts or experience misconceptions. This situation proves that a learning process is needed that can overcome this problem. The aim achieved is to determine the effect of learning using the Interactive Demonstration model on increasing understanding of the concepts of class VII students in the material of temperature, heat, and expansion. Quasi Experiment is the method used and the design refers to Posttest-Only Control Design. The posttest results for conceptual understanding in the experimental class were superior to the results obtained in the control class. So, we can conclude that understanding the concepts of temperature, heat, and expansion in class VII at SMPN 20 Pekanbaru can be improved through the application of the Interactive Demonstration model.

The Principle of Fiduciary Duty in Single-Member Limited Liability Company

Limited Liability Company in Indonesia has a conceptual expansion since the Job Creation Law has enacted. There are two types of Limited Liability Company currently, capital partnership limited liability company and single-member limited liability company. One of the most significant changes to the concept of limited liability company is related to its organs. Single-member limited liability company consists of director who also serve as shareholder. The expansion concept raises questions regarding the application of fiduciary duty to single-member limited liability company. This research uses conceptual and statute approach. The conclusion from this research is that in single-member limited liability company, there is only director who also become shareholder, thus there is no supervisory function by the board of commissioner. Secondly, the director in single-member limited liability company still has the obligation to carry out the responsibilities with the principle of fiduciary duty.

Experimental Study on Evaporation and Micro-Explosion Characteristics of Ethanol and Diesel Blended Droplets

In this study, the constant temperature control system of a heating plate was established, ethanol–diesel fuel with different proportions was prepared, and a series of experiments were carried out. The experimental system was used to observe, summarize, and analyze four evaporation and crushing modes of mixed droplets, which were explosion, liquid filament stretching, exocytosis, and ejection mode. The evaporation process of four kinds of mixed droplets in their life cycle was analyzed by normalizing the diameter square. It was proposed that the evaporation process of droplets could be divided into the following three stages: a heating stage, a fluctuating evaporation stage, and an equilibrium evaporation stage. It was also pointed out that the expansion, ejection, and micro-explosion of droplets were the causes of fluctuating evaporation. The concept of expansion and crushing intensity was put forward and the expansion and crushing intensity of ethanol/diesel mixed droplets with different proportions were calculated. The reasons why expansion and crushing intensity first increased and decreased with the increase in ethanol blending ratio were analyzed. Finally, the time proportion of ethanol–diesel mixed droplets in each evaporation stage was calculated, which explained that the time proportion of the instantaneous heating stage showed a parabolic law with the increase in ethanol content.

Beyond English centrality: integrating expansive conceptions of language for literacy programming into IEPs

This article addresses the English centrality in reading policy, assessment, and instructional practices in the U.S. and its implications for the educational programing for emerging bilingual students (EBs) with disabilities. A recent review of the state of practice as it relates to EBs with disabilities reveals concerns that have endured for nearly six decades: biased assessment, disproportionality issues in special education, and teachers’ lack of understanding of language acquisition and students’ potential. These concerns demonstrate a need for the field to prioritize multilingual lenses for both the identification of and programming for EBs with disabilities. We propose attention to conceptions of language that expand beyond the structuralist standpoint that prevails in the current science of reading reform. We offer guiding principles for IEP development grounded in sociocultural perspectives when designing bilingual instructional practices, which can be applied to the educational programming for EBs with disabilities. Within a sociocultural view of bilingualism and biliteracy, language, and literacy are understood by multiplicities in use, practice, form, and function, in which all communicators draw from expansive meaning-making repertoires, whether in listening, speaking, reading, writing, viewing, and multimodally representing. By expanding conceptions of a student’s linguistic repertoire, we honor their use of language as one, holistic system in which their named languages plus a multitude of linguistic practices intersect and interact.

Wither the Greater Eurasian Partnership? Challenges from the East in an evolving world order

AbstractThe idea of the Greater Eurasian Partnership (GEP) has gained increasing currency in Russian foreign policy. The Russia–China partnership has been presented as its bedrock through a partnership between the Eurasian Economic Union and the Belt and Road Initiative, further expanding to include other regional powers from across East Asia, South Asia, Central Asia, and Middle East as well as nonwestern multilateral groupings (SCO, ASEAN). Given the centrality of Asia‐Pacific to this expansive concept, GEP has to deal with the challenges posed by the evolving regional geopolitics of the East and the rise of the Indo‐Pacific amidst heightened US–China rivalry. The paper seeks to conduct a policy review of GEP and its proposed development format in light of ongoing changes in the East to determine the likely future of the concept in a contested region that also remains at the center of this expansive Russian vision.

Stratified GNN Explanations through Sufficient Expansion

Explaining the decisions made by Graph Neural Networks (GNNs) is vital for establishing trust and ensuring fairness in critical applications such as medicine and science. The prevalence of hierarchical structure in real-world graphs/networks raises an important question on GNN interpretability: "On each level of the graph structure, which specific fraction imposes the highest influence over the prediction?" Currently, the prevailing two categories of methods are incapable of achieving multi-level GNN explanation due to their flat or motif-centric nature. In this work, we formulate the problem of learning multi-level explanations out of GNN models and introduce a stratified explainer module, namely STFExplainer, that utilizes the concept of sufficient expansion to generate explanations on each stratum. Specifically, we learn a higher-level subgraph generator by leveraging both hierarchical structure and GNN-encoded input features. Experiment results on both synthetic and real-world datasets demonstrate the superiority of our stratified explainer on standard interpretability tasks and metrics such as fidelity and explanation recall, with an average improvement of 11% and 8% over the best alternative on each data type. The case study on material domains also confirms the value of our approach through detected multi-level graph patterns accurately reconstructing the knowledge-based ground truth.

Shifting from Equality toward Equity: Addressing Disparities in Research Participation for Clinical Cancer Research.

AbstractThere is societal consensus that cancer clinical trial participation is unjust because some sociodemographic groups have been systematically underrepresented. Despite this, neither a definition nor an ethical explication for the justice norm of equity has been clearly articulated in this setting, leading to confusion over its application and goals. Herein we define equity as acknowledging sociodemographic circumstances and apportioning resource and opportunity allocation to eliminate disparities in outcomes, and we explore the issues and tensions this norm generates through practical examples. We assess how equality-based enrollment structures in clinical cancer research have perpetuated historical disparities and what equity-based alternatives are necessary to achieve representativeness and an expansive conception of participatory justice in clinical cancer research. This framework addresses the breadth from normative to applied by defining the justice norm of equity and translating it into practical strategies for addressing participation disparities in clinical cancer research.

The Creeping Concept of Trauma

ABSTRACT: Over the past century the concept of trauma has substantially broadened its meanings in academic and public discourse. We document four directions in which this semantic expansion has occurred at different times: from somatic to psychic, extraordinary to ordinary, direct to indirect, and individual to collective. We analyze these expansions as instances of "concept creep," the progressive inflation of harm-related concepts, and present evidence for the rising cultural salience and semantic enlargement of trauma in recent decades. Expansive concepts of trauma may have mixed blessings for personal and collective identity.

Bacteria employ lysine acetylation of transcriptional regulators to adapt gene expression to cellular metabolism

The Escherichia coli TetR-related transcriptional regulator RutR is involved in the coordination of pyrimidine and purine metabolism. Here we report that lysine acetylation modulates RutR function. Applying the genetic code expansion concept, we produced site-specifically lysine-acetylated RutR proteins. The crystal structure of lysine-acetylated RutR reveals how acetylation switches off RutR-DNA-binding. We apply the genetic code expansion concept in E. coli in vivo revealing the consequences of RutR acetylation on the transcriptional level. We propose a model in which RutR acetylation follows different kinetic profiles either reacting non-enzymatically with acetyl-phosphate or enzymatically catalysed by the lysine acetyltransferases PatZ/YfiQ and YiaC. The NAD+-dependent sirtuin deacetylase CobB reverses enzymatic and non-enzymatic acetylation of RutR playing a dual regulatory and detoxifying role. By detecting cellular acetyl-CoA, NAD+ and acetyl-phosphate, bacteria apply lysine acetylation of transcriptional regulators to sense the cellular metabolic state directly adjusting gene expression to changing environmental conditions.

FSMN-Net: a free space matching network based on manifold convolution for optical molecular tomography.

Optical molecular tomography (OMT) can monitor glioblastomas in small animals non-invasively. Although deep learning (DL) methods have made remarkable achievements in this field, improving its generalization against diverse reconstruction systems remains a formidable challenge. In this Letter, a free space matching network (FSMN-Net) was presented to overcome the parameter mismatch problem in different reconstruction systems. Specifically, a novel, to the best of our knowledge, manifold convolution operator was designed by considering the mathematical model of OMT as a space matching process. Based on the dynamic domain expansion concept, an end-to-end fully convolutional codec further integrates this operator to realize robust reconstruction with voxel-level accuracy. The results of numerical simulations and in vivo experiments demonstrate that the FSMN-Net can stably generate high-resolution reconstruction volumetric images under different reconstruction systems.

The Role of Endowments in Achieving the Goals of Security and Freedom

This research explores the expansive concept of freedom within Islamic endowments, or Waqf, emphasizing liberation from societal constraints like poverty and disability. It asserts that moral constraints restrict human freedom, necessitating a call to Allah for liberation. Historical examples, such as Al-Azhar University, highlight endowments' pivotal role in fostering independence from state pressures, particularly in the realms of thought and education. Endowments are depicted as vital in sustaining and liberating society, offering financial autonomy to scholars and educational institutions. The text also delves into the economic impacts of endowments, detailing their role in employment, income redistribution, and fostering various industries. Legal perspectives on lending within the Islamic context are explored, along with the role of endowments in liberating captives and supporting those engaged in jihad. The research concludes by advocating for directing endowments towards knowledge and scholars to combat ignorance and achieve societal liberation.

Mobile Learning Simulation (MLS) for Learning Physics in Heat Transfer Concept

This research aims to develop Mobile Learning Simulation (MLS) media that is valid for learning the concept of heat transfer. The method used in this research is the Research and Development method with the ADDIE model (Analyze, Design, Develop, Implement and Evaluate). MLS was developed to make it easier for students to learn the concept of expansion and increase their understanding of the microscopic nature of heat transfer. MLS can display six 2D simulations, namely the processes of length expansion, area expansion, volume expansion, and heat transfer by conduction, convection, and radiation. The product effectiveness test was carried out with correspondents of 35 students in one of the schools in western Indonesia, obtaining an average score of 84.3% and was in the very good category. Based on the test results, the MLS application is efficient and suitable for use as a physics learning medium in high school.
