The experiences of Black students in Canadian higher education shed light on the societal and institutional challenges that influence their social and economic aspirations. In today’s societal and economic context, obtaining a postsecondary education degree is not just preferred but essential for securing the employment opportunities that most young people desire. For Black communities in particular, a university degree is often seen as the primary pathway to upward social mobility. However, Black students’ journeys toward higher education are frequently hindered by systemic barriers and institutional challenges. While there is extensive literature detailing the systemic forces that obstruct access to higher education for Black Canadians, there is limited academic focus on how these forces continue to affect Black students once they enter higher education. This article addresses this gap by investigating the educational experiences of Black students in Canadian universities, emphasizing the challenges posed by systemic racism and institutional barriers. Utilizing data from interviews and focus groups with Black undergraduate and graduate students from a university in the Greater Toronto Area (GTA), the study explores how historical and contemporary issues of anti-Black racism shape their academic journeys. It discusses the broader implications of these experiences and highlights the need for comprehensive institutional reforms to create genuinely inclusive and equitable educational environments. By centering the voices of Black students, this research aims to contribute to the ongoing dialog on racial equity in higher education. Full article

Digital Twins of the Ocean (DTO) are a rapidly emerging topic that has attracted significant interest from scientists in recent years. The initiative, strongly driven by the EU, aims to create a digital replica of the ocean to better understand and manage marine environments. The Iliad project, funded under the EU Green Deal call, is developing a framework to support multiple interoperable DTO using a federated systems-of-systems approach across various fields of applications and ocean areas, called pilots. This paper presents the results of a Water Quality DTO pilot located in the Trondheim fjord in Norway. This paper details the building blocks of DTO, specific to this environmental monitoring pilot. A crucial aspect of any DTO is data, which can be sourced internally, externally, or through a hybrid approach utilizing both. To realistically twin ocean processes, the Water Quality pilot acquires data from both surface and benthic observatories, as well as from mobile sensor platforms for on-demand data collection. Data ingested into an InfluxDB are made available to users via an API or an interface for interacting with the DTO and setting up alerts or events to support ’what-if’ scenarios. Grafana, an interactive visualization application, is used to visualize and interact with not only time-series data but also more complex data such as video streams, maps, and embedded applications. An additional visualization approach leverages game technology based on Unity and Cesium, utilizing their advanced rendering capabilities and physical computations to integrate and dynamically render real-time data from the pilot and diverse sources. This paper includes two case studies that illustrate the use of particle sensors to detect microplastics and monitor algae blooms in the fjord. Numerical models for particle fate and transport, OpenDrift and DREAM, are used to forecast the evolution of these events, simulating the distribution of observed plankton and microplastics during the forecasting period.

Religion has become an increasingly pronounced force in American politics, most notably among White evangelicals, nearly two-thirds of whom identify with Christian nationalism. This group contends that conservative, biblically rooted Christian values should determine the social and cultural landscape of our society and seeks to pass laws that help actualize this goal. This article explores the fundamental beliefs that enable White evangelicalism’s compatibility with Christian nationalism. More specifically, it considers how the myth of America’s Christian origins prompts a yearning for Christendom that—when coupled with a theological shift from a strict non-interventionist two kingdoms doctrine to a more fluid conception of kingdoms and laws—allows White evangelicals to cordon off Jesus’s life and teachings from their political activities. This relegation of Jesus to the Christian’s spiritual life enables White evangelicals to pursue a Christian ordering of society that is estranged from the person of Christ. Full article

Earthquake prediction is the holy grail of seismology and one of humanity’s greatest dreams. The Earth’s magnetic field appears to be one of the best possible precursors of earthquakes, although the topic is controversial. Recent advancements have made it possible to observe magnetic fields from satellites with great accuracy. We utilize magnetic measurements from Swarm satellites to explore the potential identification of anomalous magnetic signals preceding earthquakes. Focusing on 1077 major earthquakes that occurred in 2014–2023 in the Alpine–Himalayan belt, we apply an automatic algorithm to data recorded 10 days before each earthquake. This analysis reveals clear pre-earthquake anomalies in the magnetic field components. Notably, a robust correlation is established between the duration of these anomalies and the earthquake magnitude, indicating that as the earthquake magnitude increases, so does the duration of the anomaly. Here we show that this method has a great ability to make predictions (high accuracy 79%, precision 88%, F1-score and hit rate 84%), thus becoming the basis for an Operational Earthquake Prediction System (OEPS).

Many philosophers have approached the nature of laughter and various ideas have been put forward in the period from the classical period to the present day. One of the relevant ideas was created by the pioneers of relief theory, who sought the nature of laughter in the act of release from psychological pressure. Relief theory appears as one of the most difficult subjects to diagnose, as a result of its dependence on certain psychological conditions, within the framework of the ecology of Turkish laughter. Bektashi narratives, in which the Turkish–Islamic synthesis is intensely seen, probably take the lead among the Turkish anecdote types that can be included in the subject area of relief theory. In the Ottoman geographical region of the 13th century, Bektashism, which was established with a mystical Sufi understanding based on Hacı Bektaş Veli, started to generate products with an intense subject of laughter over time. It is known that Bektashism, which is the continuation in Anatolia of the Turkish Sufi tradition initiated by Hoca Ahmet Yesevi in the 11th century in the Khorasan region, was also respected by the Ottoman Empire for a long time. Bektashism, which is a continuation of the cultural understanding of Islam, became the subject of anecdotes as a type as a result of certain historical events. In Bektashi narratives, which are reflected in anecdotes as a type, it is easy to determine the situation that causes laughter but difficult to make an analysis of why the matter in question is laughed at. From the narrator’s point of view, there is a fear as to why he/she is telling the story, and, from the listener’s point of view, there is a feeling of having sinned because he/she is laughing. Bektashi anecdotes, which have an element of laughter other than the classical laughter elements based on equivoke, consist of a suppressed fear in their content. The act of laughter, which occurs when the suppressed fear causes sudden relief, reveals the feeling of having sinned based on the aggressive attitude of the anecdote towards religious figures that has been aroused in the person. This situation brings along the necessity of explaining the laughter element in Bektashi anecdotes with the theory of relief. The interpretation of Bektashi anecdotes based on the views of Sigmund Freud, one of the pioneers of relief theory, on laughter and its relationship with the unconscious has made it possible to evaluate this in the context of “substitution” theory. The theory of substitution, a mechanism identified by Freud on the interpretation of dreams and the content of anecdotes or jokes, occurs in cases where a statement and its response deviate from the direction indicated by the original statement. For the formation of the theory, which is characterised as a psychological deviation or a product of faulty reasoning, a subject contrary to social norms must be dealt with, laughter must not depend on equivoke and it must be found in the last response of a conversation. Based on these data, five Bektashi anecdotes have been identified using the sampling method in the article and substitution theory has been applied to the identified jokes. Full article

Suicidality in adolescents has been associated with emotional distress, stressful life events, relationship issues, and nightmares to name a few. This study explored the actual dream content and the mood at pre-sleep, during a reported dream, and in the morning in 33 adolescents admitted to the hospital on account of a suicide attempt. In all aspects, hospitalized adolescents were compared to 33 matched adolescents who had followed the same protocol. In accordance with the Continuity and the Threat Simulation theories of dream formation, it was hypothesized that the waking-life experiences of suicidal adolescents would transpire in both dream mood and content as well as in the frequency of nightmares. Dreams were analyzed by independent judges using traditional dream content scales, including for the presence of negative and destructive themes and types of interpersonal relationships. As predicted, more suicidal adolescents experienced frequent nightmares, which was significant. A higher negative mood at pre-sleep, within dreams, and at post-sleep was also observed. Furthermore, their dreams contained a higher prevalence of destructive themes and failures, as well as self-directed and death-resulting aggressions. Regression analyses indicated that morning mood was most accurately predicted by positive and negative dream mood in the normative adolescents, whereas only negative dream mood appeared to predict subsequent waking affect in suicidal participants. Our results underline the valuable potential of implementing nightmare-reducing therapies in the presence of suicidal adolescents who suffer from frequent nightmares. Full article

Studying gene regulatory networks (GRNs) is paramount for unraveling the complexities of biological processes and their associated disorders, such as diabetes, cancer, and Alzheimer’s disease. Recent advancements in computational biology have aimed to enhance the inference of GRNs from gene expression data, a non-trivial task given the networks’ intricate nature. The challenge lies in accurately identifying the myriad interactions among transcription factors and target genes, which govern cellular functions. This research introduces a cutting-edge technique, EGRC (Effective GRN Inference applying Graph Convolution with Self-Attention Graph Pooling), which innovatively conceptualizes GRN reconstruction as a graph classification problem, where the task is to discern the links within subgraphs that encapsulate pairs of nodes. By leveraging Spearman’s correlation, we generate potential subgraphs that bring nonlinear associations between transcription factors and their targets to light. We use mutual information to enhance this, capturing a broader spectrum of gene interactions. Our methodology bifurcates these subgraphs into ‘Positive’ and ‘Negative’ categories. ‘Positive’ subgraphs are those where a transcription factor and its target gene are connected, including interactions among their neighbors. ‘Negative’ subgraphs, conversely, denote pairs without a direct connection. EGRC utilizes dual graph convolution network (GCN) models that exploit node attributes from gene expression profiles and graph embedding techniques to classify these. The performance of EGRC is substantiated by comprehensive evaluations using the DREAM5 datasets. Notably, EGRC attained an AUROC of 0.856 and an AUPR of 0.841 on the E. coli dataset. In contrast, the in silico dataset achieved an AUROC of 0.5058 and an AUPR of 0.958. Furthermore, on the S. cerevisiae dataset, EGRC recorded an AUROC of 0.823 and an AUPR of 0.822. These results underscore the robustness of EGRC in accurately inferring GRNs across various organisms. The advanced performance of EGRC represents a substantial advancement in the field, promising to deepen our comprehension of the intricate biological processes and their implications in both health and disease.

Dream research today assumes that there is a connection between dreams and waking life. However, the structural alteration of dream motifs in connection with the psychotherapeutic process and waking life has not yet been researched extensively. This study depicts the development of the new Motif Analysis and Phase Model (MAP), a dynamic method which allows research on the previous aspects. The following question was investigated as an accompanying key issue: can a connection be established between the course of the dream patterns and the agency of the dream ego as well as the dream contents and the course of the psychotherapies of the dreaming person as a whole? Four hypotheses were formulated and tested. The data material consists of 217 dreams of a male test subject. The motifs were analysed using Structural Dream Analysis (SDA) at first. Thereafter, the content was linked to the test subject’s waking life in a guided interview. The findings show a strong connection between the dream content and the psychotherapies as well as the test subject’s waking life. Five motifs with structural changes were found, through which the Phase Model with four phases was developed. At turning points, the transformative child motif also appears in the dreams. The course of the dream patterns and agency of the dream ego, however, has not changed. The results, the method and the generalisability were critically discussed and recommendations for future research were formulated. Full article

In the 7th century BCE, the Kushite king Tanwetamani commissioned his “Dream Stela”, which was to be erected in the Amun Temple of Jebel Barkal. The lunette of the stela features a dualistic artistic motif whose composition, meaning, and significance are understudied despite their potential to illuminate important aspects of royal Kushite ideology. On the lunette, there are two back-to-back offering scenes that appear at first glance to be nearly symmetrical, but that closer inspection reveals to differ in subtle but significant ways. Analysis of the iconographic and textual features of the motif reveals its rhetorical function in this royal context. The two strikingly similar but meaningfully different offering scenes represented the two halves of a Kushite “Double Kingdom” that considered Kush and Egypt together as a complementary geographic dual, with Tanwetamani presiding as king of both. This “Mirrored Motif” encapsulated the duality present in the Kushite ideology of kingship during the Twenty-Fifth Dynasty, which allowed Tanwetamani to reconcile the present imperial expansion of Kush with the history of Egyptian activity in Nubia. The lunette of the Dream Stela is therefore political art that serves to advance the Kushite imperial agenda. Full article

Young organizers are increasingly calling for social movements to center healing alongside activism as they build political power. Campaigns that solely focus on policy wins or base-building can lead to burnout and frustration. Sociopolitical action is more likely to be sustained if accompanied by experiences of care, belonging, and mutual support. Such an approach makes sociopolitical wellbeing central to organizing. Although the research literature has offered conceptualizations of healing, and compelling evidence of health-related outcomes, we still lack empirical examples of what it looks like for youth community organizing (YCO) groups to weave a commitment to healing into sustained collective action. Drawing on qualitative data from the Powerful Youth, Powerful Communities International Study on Youth Organizing, we define and demonstrate three interconnected healing-oriented values that foster what we characterize as sociopolitical wellbeing. The three values, which we illustrate via fieldnotes and interview excerpts, are collectivized care, spiritual activism, and freedom dreaming. YCO holds promising implications for supporting youth engagement in democratic movements for education, racial, gender, economic, and environmental justice. Full article

Starting from the concept of death in contemporary Serbian culture (in the context of thanatological and anthropological studies), the author focuses on the analysis of communication with the deceased in dreams, which is still perceived as an important form of contact with the otherworldly. The analysis of material collected during field research at various locations in Serbia and in Serbian communities in Romania (from 2017 to 2024), supplemented by dream narratives from the internet, has shown that based on the main messages conveyed by the deceased to the living, dreams can be divided into: (1) dreams about “the unappeased deceased” (who lack something in the otherworld, usually due to an omission by the living related to funerary rituals); (2) dreams in which the deceased show the otherworld and provide verbal assessments of it; (3) dreams in which the deceased inform of their departure or final passing into the world of the dead; (4) dreams in which the deceased demonstrate their presence in the world of the living, i.e., providing information pertaining to the sphere of the dreamer’s social reality; (5) dreams in which the deceased convey their messages, advice or warnings to the living; and (6) dreams interpreted as the deceased person’s call to the dreamer to join them in the otherworld. Basic element analysis of the spatial world image, projected via the dream, highlights the importance of the locus perceived as a border space. Dreams about the deceased seem to be ambivalent in this respect, given that, on the one hand, they are perceived as an important means of communication between this world and the otherworld, and on the other hand, through the ideas on which they are founded and that they further transmit, they are also part of the narrative strategies of the boundary between this concept of two worlds.

A body of experimental research has aimed to investigate processes underlying dream formation by examining the effects of a range of pre-sleep stimuli and events on subsequent dream content. Given its ever-growing presence and salience in people’s everyday lives, pre-sleep media consumption stands out as a key variable that could influence people’s dreams. We conducted a scoping review to evaluate the experimental evidence of the effects of pre-sleep exposure to visual media on dream content. A systematic search on PubMed, PsycInfo, and Web of Science using terms related to moving visual media and dreams yielded 29 studies meeting the inclusion criteria. Overall, we found modest yet varied effects of pre-sleep exposure to visual media on dream content, with rates of stimulus-related incorporation ranging from 3% to 43% for REM dream reports, 4% to 30% for NREM sleep mentation reports, and between 11% and 35% for home dream reports. Our review highlights the large methodological heterogeneity and gaps across studies, the general difficulty in influencing dream content using pre-sleep exposure to visual media, and suggests promising venues for future research to advance our understanding of how and why digital media may impact people’s dreams.

Nowadays, dried lake beds constitute the largest source of saline dust storms, with serious environmental and health issues in the surrounding areas. In this study, we examined the spatial–temporal distribution of monthly and annual dust events of varying intensity (dust in suspension, blowing dust, dust storms) in the vicinity of the desiccated Urmia Lake in northwestern (NW) Iran, based on horizontal visibility data during 2009–2022. Dust in suspension, blowing dust and dust storm events exhibited different monthly patterns, with higher frequencies between March and October, especially in the southern and eastern parts of the Urmia Basin. Furthermore, the intra-annual variations in aerosol optical depth at 500 nm (AOD₅₅₀) and Ångström exponent at 412/470 nm (AE) were investigated using Terra/Aqua MODIS (Moderate Resolution Imaging Spectroradiometer) data over the Urmia Lake Basin (36–39°N, 44–47°E). Monthly distributions of potential coarse aerosol (AE < 1) sources affecting the lower troposphere over the Urmia Basin were reconstructed, synergizing Terra/Aqua MODIS AOD₅₅₀ for AE < 1 values and HYSPLIT_4 backward trajectories. The reconstructed monthly patterns of the potential sources were compared with the monthly spatial distribution of Terra MODIS AOD₅₅₀ in the Middle East and Central Asia (20–70°E, 20–50°N). The results showed that deserts in the Middle East and the Aral–Caspian arid region (ACAR) mostly contribute to dust aerosol load over the Urmia Lake region, exhibiting higher frequency in spring and early summer. Local dust sources from dried lake beds further contribute to the dust AOD, especially in the western part of the Urmia Basin during March and April. The modeling (DREAM8-NMME-MACC) results revealed high concentrations of near-surface dust concentrations, which may have health effects on the local population, while distant sources from the Middle East are the main controlling factors to aerosol loading over the Urmia Basin.

The original conceptualization of REM sleep as paradoxical sleep was based on its EEG resembling wakefulness and its association with dreaming. Over time, the concept of paradox was expanded to include various associations with REM sleep, such as dream exclusivity, high recall, and pathophysiology. However, none of these associations are unique to REM sleep; they can also occur in other sleep states. Today, after more than fifty years of focused research, two aspects of REMS clearly retain paradoxical exclusivity. Despite the persistent contention that the EEG of human REMS consists of wake-like, low-voltage, non-synchronous electrical discharges, REMS is based on and defined by the intracranial electrical presence of 5–8 Hz. theta, which has always been the marker of REMS in other animals. The wake-like EEG used to define REMS on human polysomnography is secondary to a generalized absence of electrophysiological waveforms because the strong waves of intracranial theta do not propagate to scalp electrodes placed outside the skull. It is a persistent paradox that the theta frequency is restricted to a cyclical intracranial dynamic that does not extend beyond the lining of the brain. REMS has a persistent association with narratively long and salient dream reports. However, the extension of this finding to equate REMS with dreaming led to a foundational error in neuroscientific logic. Major theories and clinical approaches were built upon this belief despite clear evidence that dreaming is reported throughout sleep in definingly different physiologic and phenomenological forms. Few studies have addressed the differences between the dreams reported from the different stages of sleep so that today, the most paradoxical aspect of REMS dreaming may be how little the state has actually been studied. An assessment of the differences in dreaming between sleep stages could provide valuable insights into how dreaming relates to the underlying brain activity and physiological processes occurring during each stage. The brain waves and dreams of REMS persist as being paradoxically unique and different from waking and the other states of sleep consciousness. Full article

Prosthetic joint infection (PJI) is one of the most serious complications of joint replacement surgery among orthopedic surgeries and occurs in 1 to 2% of primary surgeries. Additionally, the cause of PJIs is mostly bacteria from the Staphylococcus species, accounting for more than 98%, while fungi cause PJIs in only 1 to 2% of cases and can be difficult to manage. The current gold-standard microbiological method of culturing synovial fluid is time-consuming and produces false-negative and -positive results. This study aimed to identify a novel, accurate, and convenient molecular diagnostic method. The DreamDX primer–hydrolysis probe set was designed for the pan-bacterial and pan-fungal detection of DNA from pathogens that cause PJIs. The sensitivity and specificity of DreamDX primer–hydrolysis probes were 88.89% (95% CI, 56.50–99.43%) and 97.62% (95% CI, 87.68–99.88%), respectively, compared with the microbiological method of culturing synovial fluid, and receiver operating characteristic (ROC) area under the curve (AUC) was 0.9974 (*** p < 0.0001). It could be concluded that the DreamDX primer–hydrolysis probes have outstanding potential as a molecular diagnostic method for identifying the causative agents of PJIs, and that host inflammatory markers are useful as adjuvants in the diagnosis of PJIs.
