Background/Objectives: Older adults with an LGBT+ identity represent an under-researched population within healthcare systems. Existing evidence suggests that they experience distinct health challenges compared to their heterosexual counterparts, partly shaped by lifelong experiences of stigma and discrimination. Such experiences may contribute to minority stress, which is associated with adverse mental health outcomes and lifestyle-related health issues. This review aims to synthesise the existing literature on how older adults with an LGBT+ identity experience encounters with healthcare. Methods: An integrative literature review was conducted following PRISMA guidelines. A systematic search of multiple databases was performed, and studies were screened using predefined inclusion and exclusion criteria. Data were analysed using systematic text condensation. Results: A total of 18 studies were included, comprising approximately 450 participants. All studies contained a qualitative component. Three overarching themes were identified: (1) double-edged discrimination—experiences of stigma and anticipated fear in healthcare; (2) relational networks as essential yet fragile sources of support in later life; and (3) healthcare practices as shaping inclusion or invisibility—the need for competence and recognition. Conclusions: The findings highlight significant barriers faced by older adults with an LGBT+ identity in healthcare, including fear of discrimination and challenges related to disclosure. Social networks play a crucial role as sources of support, while healthcare professionals’ competencies and practices are central to ensuring inclusive and equitable care. Full article

The Jiaodong gold-mineralized area is one of the most significant gold districts in China. The newly discovered Moshan gold deposit is hosted in the Late Jurassic Queshan granite, previously considered a prospecting blind zone. In this study, pyrite from the Moshan gold deposit is examined as the primary research subject. To elucidate the ore-forming processes and genetic mechanisms of this deposit, we conducted a comprehensive mineralogical and geochemical study on pyrite, the principal gold-bearing mineral. EPMA and LA-MC-ICP-MS analyses reveal that the pyrite is slightly sulfur-deficient (average S/Fe ratio of 1.976) and exhibits trace element variations (As, Co, and Ni) strongly correlated with distinct metallogenic stages. Gold occurs in various forms, including visible inclusion gold, fracture gold, and invisible nano-particulate gold (Au⁰). The in situ sulfur isotope δ³⁴S values range from 7.11‰ to 9.40‰ (average 8.00‰), displaying high homogeneity and a positive deviation from the troilite in the Canyon Diablo iron meteorite. By integrating pyrite S-Fe relationships, Co-Ni-As systematics, and sulfur isotope characteristics, the study indicates that the Moshan gold deposit originates from a magmatic-hydrothermal source. The ore-forming materials predominantly derive from Mesozoic granite-derived magmatic-hydrothermal fluids, with a minor contribution from crustal basement materials. The depth of mineralization is interpreted as mid-shallow. These findings not only highlight the metallogenic potential of the Queshan granite and clarify the genetic relationship between the Moshan gold deposit and other regional gold deposits but also provide a novel theoretical foundation and technical support for deep gold exploration in the Jiaodong region.

Workplace harassment of transgender employees remains pervasive and understudied. In this narrative review of 63 studies over the past 25 years, we summarize the literature on transgender workplace harassment. We focus on its prevalence and forms. Individual, organizational and cultural factors contribute to its occurrence; psychological and occupational outcomes; and strategies to reduce or prevent harassment. We find that harassment often extends beyond traditional definitions; includes misgendering, deadnaming, and the questioning or outright denial of one’s gender identity; and is particularly pervasive in masculinity contest cultures. These experiences are associated with both negative well-being of transgender employees and less effectiveness of the organizations that employ them, though more causal evidence is needed. We also highlight critical conceptual and methodological gaps to guide future research. Much of the existing research on LGBTQ+ employees in the workplace has focused primarily on sexual minorities, leaving the unique experiences of gender minorities invisible. Further, an intersectional lens is needed, as harassment experiences of trans women, trans men, and nonbinary people may differ in significant ways. Finally, we identify strategies to improve workplace climate including both top-down formal policy and bottom-up interpersonal behaviors. Full article

Drawing on social comparison and attribution theories, this study examines how employees’ attitudinal dissimilarity within work groups shapes their willingness to speak up or remain silent. We conceptualize dissimilarity in psychological ownership and job stress as individual-level differences that trigger internal attributions, leading employees to direct attention inward and reduce their likelihood of speaking up. In contrast, dissimilarity in perceived status conflict, an individual-level perception of a structural feature of the group, induces external attributions toward the social system, motivating employees to express voice aimed at preserving or challenging the status quo. Using multi-source data from 202 employees nested in 39 work groups in South Korea, hierarchical regression analyses support all proposed hypotheses: individual-level dissimilarities are negatively related and structural-level dissimilarity is positively related to voice. These findings reveal that the behavioral consequences of difference depend on where attribution is directed—toward the self or the system. The study contributes to the voice literature by integrating attributional reasoning into social comparison processes and by identifying two forms of attitudinal minorities: invisible minorities who remain silent, and boisterous minorities who speak up for change.

Nutrition is a cornerstone of public health, yet the unique nutrition needs and considerations of lesbian, gay, bisexual, transgender, and others (LGBT+) communities remain largely invisible in the field of dietetics. These populations face disproportionate burdens of obesity, eating disorders, body dysmorphia, metabolic risks, and food insecurity, often driven by stigma, minority stress, and structural inequities. This narrative review aimed to synthesize current evidence on nutrition-related disparities among LGBT+ populations and identify opportunities for dietitians to advance equity in care. A comprehensive search of PubMed, Scopus, and Web of Science was conducted for studies addressing diet quality, obesity, eating disorders, food insecurity, and metabolic health in sexual and gender minorities. Evidence indicates clear subgroup differences: lesbian and bisexual women are more likely to experience obesity and food insecurity; gay and bisexual men report lower BMI but greater body image concerns and disordered eating; transgender individuals face nutritional challenges linked to gender-affirming therapy and high rates of food insecurity; and people living with HIV encounter additional metabolic risks associated with treatment. Despite these findings, LGBT+ health remains rarely reflected in dietary guidelines or professional training. Embedding inclusivity into dietetic education and clinical encounters, adopting culturally competent and structurally aware practices, and tailoring interventions to subgroup-specific needs are key priorities. Inclusive, equity-driven, and person-centered nutrition care is essential to closing health gaps for LGBT+ populations and ensuring that every patient receives guidance that affirms their identity and lived experience.

In the wake of the Holocaust and the post-war reconstruction of Greece’s historic city centers, many Greek synagogues were demolished, abandoned, or appropriated, erasing centuries of Jewish architectural and communal presence. This study presents a thirty year-long research and documentation initiative aimed at preserving, recovering, and eventually digitally reconstructing these “lost” synagogues, both as individual buildings and within their urban context. Drawing on architectural surveys, archival research, oral histories, and previously unpublished materials, including the recently rediscovered Shemtov Samuel archive, the project grew through the use of technology. Beginning with in situ surveys in the early 1990s, it evolved into full-scale digitally enhanced architectural drawings that formed the basis for further digital exploration, 3D models, and virtual reality outputs. With the addition of these new tools to existing documentation, the project can restore architectural detail and cultural context with a high degree of fidelity, even in cases where only fragmentary evidence survives. These digital reconstructions have informed physical restoration efforts as well as public exhibitions, heritage education, and urban memory initiatives across Greece. By reintroducing “invisible” Jewish landmarks into contemporary consciousness, the study addresses the broader implications of post-war urban homogenization, the marginalization of minority heritage, and the ethical dimensions of digital preservation. This interdisciplinary approach, which bridges architectural history, digital humanities, urban studies, and cultural heritage, demonstrates the value of digital tools in reconstructing “lost” pasts and highlights the potential for similar projects in other regions facing comparable erasures.

Teacher education is paramount for nurturing democratic, critical, and participative citizenship. Educators should approach identity formation from an intersectional perspective, encompassing sex–gender, racial, and cultural diversities. This perspective highlights social inequalities and challenges the power structures that sustain them. Teachers play a crucial role in shaping and reflecting on these identities since their responsibilities extend beyond knowledge transmission. Their ability to incorporate intersectional perspectives into teaching influences students’ understanding of intersectionality, thereby supporting the development of inclusive identities and promoting democratic citizenship. This article opens with the results of research on how trainee teachers acquire competencies in feminist critical visual literacy. Following this review, we analyzed educational materials to examine stereotypes, racism, and the invisibility of racialized and cultural minority communities. We also addressed the identification and counteraction of hate speech targeting the LGTBIQ+ community as well as different gender-based violence. Comparative data from participating universities provide insights into the critical skills of pre-service teachers across international contexts. This study highlights an urgent need for further research into integrating intersectionality in teacher training, supported by educational policies that strengthen critical competencies through a holistic, gender- and race-sensitive approach aimed at social justice. These initiatives would promote an education system responsive to multifaceted diversities. Full article

Religious places represent one of the most significant categories of protected heritage. In Italy, however, places of worship belonging to minority communities often remain inconspicuous and are not legally recognized as part of the nation’s cultural heritage. Consequently, the histories of these communities face challenges in securing a space within the collective memory. This contribution, through a spatial approach and an interdisciplinary methodology, highlights the richness of the hidden heritage—both tangible and intangible—of the Greek Orthodox Church of the Nativity of St. John the Baptist in Turin. In particular, this research explores the role of the Greek language, which constitutes a significant element of intangible heritage for the community. Since the 1960s, regular celebrations in the Byzantine rite and the Greek language have been held in the Piedmontese capital. These biritual practices emerged in response to the demands of numerous Greek university students and families who revitalized the Orthodox presence in the territory during those years. In 2000, the Catholic Archdiocese granted the Greek Orthodox community the use of a church in the city’s historic center. This church is interpreted as a shared religious space, having undergone a transformation of identity over time: its Orthodox identity remains architecturally invisible, as the community continues to worship in a former Catholic church.

The newly discovered Erdaodianzi gold deposit in southern Jilin Province, Northeast China, is located in the eastern segment of the northern margin of the North China Craton (NCC). It is a large-scale gold deposit with reserves of 38.4 tons of gold. Gold mineralization in the ore district primarily occurs in gold-bearing quartz–sulfide veins. The gold ore occurs mainly as vein, veinlet, crumby, and disseminated structures. The hydrothermal process can be divided into three stages: stage I, characterized by quartz, arsenopyrite, and pyrite; stage II, featuring quartz, arsenopyrite, pyrite, pyrrhotite, chalcopyrite, sphalerite, and native gold; and stage III, consisting of quartz, pyrite, sphalerite, galena, electrum (a naturally occurring Au–Ag alloy), and calcite. Electrum and native gold primarily occur within the fissures of the polymetallic sulfides. To determine the enrichment mechanism of the Au element and the genetic types of ore deposits in the Erdaodianzi deposit, sourcing in situ trace element data, element mapping and sulfur isotope analysis were carried out on sphalerites from different stages using LA-ICP-MS. Minor invisible gold, in the form of Au–Ag alloy inclusions, is present within sphalerites, as revealed by time-resolved depth profiles. The LA-ICP-MS trace element data and mapping results indicate that trivalent or quadrivalent cations, such as Sb³⁺ and Te⁴⁺, exhibit a strong correlation with Au. This correlation can be explained by a coupled substitution mechanism, where these cations (Sb³⁺ and Te⁴⁺) replace zinc ions within the mineral structure, resulting in a strong association with Au. Similarly, the element Pb exhibits a close relationship with Au, which can be attributed to the incorporation of tetravalent cations like Te⁴⁺ into the mineral structure. The positive correlation between Hg and Au can be attributed to the formation of vacancies and defects within sphalerite, caused by the aforementioned coupled substitution mechanism. A slight positive relationship between Au and other divalent cations, including Fe²⁺, Mn²⁺, and Cd²⁺, may result from these cations simply replacing Zn within the sphalerite lattice. The crystallization temperatures of the sphalerite, calculated via the Fe/Zn ratio, range from 238 °C to 320 °C. The δ³⁴S values are divided into two intervals: one ranging from −1.99 to −1.12‰ and the other varying from 10.96 to 11.48‰. The sulfur isotopic analysis revealed that the ore-forming materials originated from magmatic rock, with some incorporation of metamorphic rock. Comparative studies of the Erdaodianzi gold deposit and other gold deposits in the Jiapigou–Haigou gold belt have confirmed that they are all mesothermal magmatic–hydrothermal lode gold deposits formed at the subduction of the Paleo-Pacific Plate beneath the Eurasian Plate during the Middle Jurassic. The Jiapigou–Haigou gold belt extends northwest to the Huadian area of Jilin province. This suggests potential for research on gold mineralization in the northwest of the belt and indicates a new direction for further gold prospecting in the region. Full article

The Dapingzhang Cu-polymetallic deposit in Yunnan is a volcanic massive sulfide (VMS) deposit, located on the western edge of the Lanping–Simao block. Recently, gold-rich polymetallic orebodies with significant economic value have been discovered. However, the occurrence and enrichment mechanisms of the gold remain unclear. This study investigates the massive sulfide orebodies (V₁) through detailed geological surveys. Techniques such as optical microscopy, scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), and electron probe microanalysis (EPMA) were used to clarify the occurrence of gold, and to reveal the enrichment mechanisms. The genesis of the orebodies consists of three stages: (I) pyrite–quartz, (II) pyrite–chalcopyrite–sphalerite–galena–quartz, and (III) pyrite–chalcopyrite–sphalerite–galena–quartz–calcite. Gold precipitated during each of these mineralization stages, and it may be described as multiphase mineralization. Gold predominantly exists as invisible gold (≤0.1 μm), with minor visible gold as native gold and independent minerals (küstelite, electrum, calaverite). Invisible gold mainly occurs as gold microinclusions (Au⁺) in pyrite, chalcopyrite, and sphalerite. Combined with the previous research, comprehensive analysis determined that deep-circulating seawater, driven by a magmatic hydrothermal system, leaches and dissolves mineralizing materials from underlying volcanic rocks. The mineralizing fluid, mixed with magmatic fluid, migrates upward through volcanic conduits or is expelled to the seafloor. Changes in physicochemical conditions lead to the co-precipitation of gold and sulfides, forming a mineralization structure with lower channel facies and upper eruptive facies. Full article

Objective: We aimed to investigate the association between the angular trajectory of the vestibular aqueduct (ATVA) with other radiological parameters of temporal bone and clinical characteristics in patients with Ménière’s disease (MD). Methods: A total of 125 unilateral MD patients and 118 controls were enrolled. Computer tomography (CT)-based radiological parameters included ATVA, vestibular aqueduct (VA) visibility, VA morphology, the vertical part of the posterior semicircular canal—the posterior fossa distance (PPD), and peri-VA pneumatization. The clinical characteristics of MD patients included gender, age of diagnosis/onset, disease duration, migraine history, clinical staging, and the results of audio-vestibular tests. The radiological parameters and clinical characteristics in MD patients were compared. Results: Compared with control ears, ATVA ≥ 140° was more prevalent and ATVA ≤ 120° was less frequent in the MD-affected side. For the MD-affected side, MD patients with ATVA ≥ 140° exhibited more severe VA invisibility and obliteration and higher male preponderance than those with ATVA ≤ 120°. Other radio-clinical features did not differ between these two subgroups. Conclusion: In the current study, ATVA ≥ 140°, an indicator of a hypoplastic endolymphatic sac, was found in approximately one-third of the affected and unaffected ears of patients with MD, as well as in a minority of controls. This suggests that the indices may be a predisposing factor rather than a specific marker for the MD ear. The male preponderance in MD patients with hypoplastic ES suggests a gender difference in the anatomical factors for MD pathogenesis. Full article

The safety and robustness of convolutional neural networks (CNNs) have raised increasing concerns, especially in safety-critical areas, such as medical applications. Although CNNs are efficient in image classification, their predictions are often sensitive to minor, for human observers, invisible modifications of the image. Thus, a modified, corrupted image can be visually equal to the legitimate image for humans but fool the CNN and make a wrong prediction. Such modified images are called adversarial images throughout this paper. A popular method to generate adversarial images is backpropagating the loss gradient to modify the input image. Usually, only the direction of the gradient and a given step size were used to determine the perturbations (FGSM, fast gradient sign method), or the FGSM is applied multiple times to craft stronger perturbations that change the model classification (i-FGSM). On the contrary, if the step size is too large, the minimum perturbation of the image may be missed during the gradient search. To seek exact and minimal input images for a classification change, in this paper, we suggest starting the FGSM with a small step size and adapting the step size with iterations. A few decay algorithms were taken from the literature for comparison with a novel approach based on an index tracking the loss status. In total, three tracking functions were applied for comparison. The experiments show our loss adaptive decay algorithms could find adversaries with more than a 90% success rate while generating fewer perturbations to fool the CNNs. Full article

Electron backscatter diffraction (EBSD) methods are used to investigate the presence of microstructures in pyrite from the giant breccia-hosted Olympic Dam iron–oxide copper gold (IOCG) deposit, South Australia. Results include the first evidence for ductile deformation in pyrite from a brecciated deposit. Two stages of ductile behavior are observed, although extensive replacement and recrystallization driven by coupled dissolution–reprecipitation reaction have prevented widespread preservation of the earlier event. Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) element maps of pyrite confirm that many pyrite grains display compositional zoning with respect to As, Co, and Ni, but that the zoning is often irregular, patchy, or otherwise disrupted and are readily correlated with observed microstructures. The formation of ductile microstructures in pyrite requires temperatures above ~260 °C, which could potentially be related to heat from radioactive decay and fault displacements during tectonothermal events. Coupling EBSD methods with LA-ICP-MS element mapping allows a comprehensive characterization of pyrite textures and microstructures that are otherwise invisible to conventional reflected light or BSE imaging. Beyond providing new insights into ore genesis and superimposed events, the two techniques enable a detailed understanding of the grain-scale distribution of minor elements. Such information is pivotal for efforts intended to develop new ways to recover value components (precious and critical metals), as well as remove deleterious components of the ore using low-energy, low-waste ore processing methods.

The prejudices that have traditionally been held against female delinquency and the numerical minority of women in the prison system have led to the invisibility of their needs and characteristics as well as to many situations of inequality while they are incarcerated. This study is aimed at exploring the gender discrimination perceived by women in Spanish prisons. To this end, a scale for perception of gender discrimination is applied to a sample of incarcerated women. Qualitative data from a questionnaire administered to prison professionals and field notes are also used. The results show that incarcerated women perceive the existence of several situations of discrimination related to socio-educational intervention and to the adaptation of prisons to their unique needs, especially for those housed in male prisons. Prison professionals hold similar views and express their concern about the feminization of activities. The study has implications for the prison system and policy makers, including the implementation of gender-responsive programming in women’s prisons, the development of periodic assessments of the experiences faced by incarcerated women, and the training of prison staff.

Research shows that successful development of sexual identity is essential for healthy and well-adjusted ageing. Gay and bisexual (GB) older people have experienced cumulative events throughout their lives that may have affected the development of their identity. In addition, the few previous studies show an alarming lack of community connectedness among older GB people in Portugal. This study assessed the factors that have contributed to the development of sexual identity in Portuguese GB older adults throughout their lives, using an inductive qualitative cross-sectional approach based on Life Course Theory. Twenty-two semi-structured interviews were carried out with older (60+ years) GB people living in the community and using the lifeline technique. The interviews were analyzed using thematic analysis with a codebook approach. Results suggest a multifactorial contribution of factors throughout the life cycle that have affected the development of GB older people’s sexual identity. These include historical–cultural factors (e.g., sexual repression and traditionalism of the dictatorship), psychosocial factors (e.g., cumulative sexual stigma), relational factors (e.g., relational clandestinity) and intrapersonal factors (e.g., concealment of sexual orientation). The existence of the Internalized Sexual Minority Disconnectedness phenomenon and its contribution to the formation of the sexual identity of older GB adults were also verified. These results reveal important clues about the development of older GB people in Portugal and the factors that may be affecting the current invisibility of these people in the social and health-related context. Relevant implications for the clinical context are also discussed. Full article
