  • Atom is prematurely split in the ‘golden age’ transatlantic partnership | Nils Pratley

    Atom is prematurely split in the ‘golden age’ transatlantic partnership | Nils Pratley

    It had all been so harmonious two months ago. “Together with the US, we’re building a golden age of nuclear that puts both countries at the forefront of global innovation and investment,” purred the prime minister about the new “landmark” UK-US nuclear partnership.

    Now there’s an atomic split over the first significant decision. The UK has allocated Wylfa on the island of Anglesey, or Ynys Môn, to host three small modular reactors (SMRs) to be built by the British developer Rolls-Royce SMR. The US ambassador, Warren Stephens, says his country is “extremely disappointed”: he wanted Westinghouse, a US company, to get the gig for a large-scale reactor.

    This quarrel is easy to adjudicate. The US ambassador is living in dreamland if he seriously thought the UK wouldn’t show home bias at Wylfa. This is the coveted site for new nuclear power in the UK because the land is owned by the government, which ought to make the planning process easier and quicker, and the site hosted a Magnox reactor until 2015, so the locals are used to nuclear plants. Since Rolls-Royce’s kit is the best national hope of reviving the UK’s industry with homegrown technology, of course there was going to be preferential treatment.

    None of which is to say the SMR experiment will definitely succeed in the sense of demonstrating cheapness (a relative measure in nuclear-land) versus mega-plants, such as Hinkley Point C, Sizewell C or the Westinghouse design. Rolls-Royce oozes confidence about the cost-saving advantages of prefabrication in factories, but these have yet to be demonstrated on the ground. The point, though, is that the only way to find out is to get on and build. Rolls-Royce SMR’s only other order currently is from the Czech Republic for six units.

    Indeed, the criticism from some quarters is that the UK government has been too timid in ordering only three. If the batch-production is supposed to be the gamechanger on costs, goes the argument, then commit to a decent-sized batch at the outset.

    The choice of Wylfa may help on that score in time, though. The site is reckoned to be big enough to hold an additional five SMR units eventually, on the top of the first three. Since each SMR is 470 megawatts, a full build-out would equate to more megawatts in total than the 3,200 from each of Hinkley and Sizewell.

    The sop to the US is that Westinghouse gets to compete for future large-scale reactor projects in the UK. It would probably have been a good idea to tell the ambassador in advance before he blew a fuse. Reserving Wylfa for Rolls-Royce SMRs was the only sensible decision here.

    Hopes that SMR technology will become a major export-earner for the UK eventually are best treated with extreme caution at this stage. The first electricity from Wylfa won’t be generated until the mid-2030s, and the demonstration of falling costs with each additional unit can only come after that. There is a long way to go. But a good way to maximise your chance of success is to give the top site to your pet project. The US would have done exactly the same.

    Background

    Stigma, a term originating in ancient Greece, was initially used to refer to physical marks on an individual’s body that signified their status as a criminal, slave, or traitor []. In contemporary times, the concept of stigma can include labeling, stereotyping, social exclusion, status loss, and discrimination against individuals []. People with substance use disorders frequently experience stigma, which can adversely impact different aspects of their lives, including physical and mental well-being, employment opportunities, social status, relationships, health care, and more [,]. Specifically, the negative impacts may include reduced social functioning [], social disapproval and labeling [], distrust in health care providers and reluctance to seek treatment [,], delayed recovery [], and insufficient health care [].

    Understanding factors that shape substance use stigma experiences is necessary for effective intervention design for stigma reduction, substance use recovery, and improvement of overall mental and physical health. In this study, we focused on 3 groups of factors: substances, stigma mechanisms, and ecological factors. We focused on 3 substances—alcohol, cannabis, and opioids. Due to differences in legality, societal acceptance, and other considerations, we expected the nature of stigma-related experiences with each substance to differ.

    We studied 3 stigma mechanisms—enacted, anticipated, and internalized stigma, as defined in the stigma framework [,]. Enacted stigma refers to direct experiences of stereotyping and discrimination enacted by another individual because of a stigmatized attribute []. One example is being called a “drug addict” by another person. Anticipated stigma is the expectation that others might hold stereotypical and discriminatory views toward the self [], for example, hiding liquor bottles from family members due to fear of judgment. Internalized stigma, also known as self-stigma, is the experience of devaluation, shame, unworthiness, and guilt caused by applying the negative beliefs of society concerning a stigmatized attribute to the self [,].

    Substance use stigma experiences are largely influenced by an individual’s interaction with their immediate physical, social, and cultural environments and the people around them [,,,]. Thus, it is valuable to adopt an ecological approach to examine the significant determinants at different levels of influence []. While similar approaches have been used in research concerning other groups, particularly persons who experience HIV stigma [,], there is a notable gap in understanding stigma in the context of substance use from a social ecological perspective.

    We adapted the social ecological framework (SEF), which is frequently used for health promotion and intervention design [], to hypothesize key constructs related to substance use stigma. The SEF is particularly suited for this research because it offers a comprehensive perspective that captures the influence of factors across multiple levels, including individual, interpersonal, contextual, community, and societal. This makes it a robust framework for interpreting health behaviors and developing interventions at the population level []. In addition, the SEF is a flexible framework that can be applied to focus on specific contexts, often referred to as settings [,]. Adapting from definitions in previous research, we defined behavior settings to be physical and conceptual settings where substance use stigma takes place [,]. We identified 5 behavior settings at the contextual level of influence in the SEF—home, school, work, leisure, and health care—that are potentially insightful for examining stigma manifestations and 5 actors—family, partners, friends, coworkers, and health care providers—who may play a role in these scenarios.

    Using the ecological features, we aimed to identify characteristic ways in which stigma manifests, or stigma phenotypes, from social media data to better understand experiences of stigma in diverse social ecological contexts. We conceptualized a stigma phenotype as a distinct combination of features along 4 key dimensions: stigma mechanism, substance, setting, and actor. We sought to identify the patterns of co-occurrence of stigma mechanisms (internalized, anticipated, and/or enacted) with respect to different substances (alcohol, cannabis, and/or opioids) within diverse settings (home, work, school, leisure, and/or health care) and involving different actors (family, partners, and/or friends). The identification of stigma phenotypes can, in turn, provide valuable insights that inform the design of customized interventions tailored to different target groups.

    There is a significant gap in the literature regarding the use of extensive, naturally occurring data to analyze experiences of substance use stigma. Most of the extant literature on this topic has used survey or interview methods, typically involving small to moderate sample sizes []. Social media enables the collection of extensive, naturally occurring data, which is not easily achievable in laboratory settings []. Reddit has been frequently used in substance use research as it provides a rich body of pseudoanonymous, user-generated content and features subreddits, or discussion forums, dedicated to topics related to substance use [-]. Given the volume of data, we leveraged natural language processing (NLP) and machine learning (ML) methods to derive the defining features of stigma phenotypes.

    Objectives

    The purpose of this study was to examine stigma phenotypes in social media data to ensure a comprehensive and nuanced understanding of how substance use stigma operates within and across different ecological contexts. Cluster analysis is an unsupervised ML method that can reveal hidden patterns within a dataset and groups data points into clusters based on identified patterns []. Due to its ability to identify natural groupings within datasets [], cluster analysis methods have been frequently used in biomedical research to extract disease phenotypes [-]. We performed cluster analysis to extract stigma phenotypes delineated by stigma mechanisms, substances, and ecological factors (behavior settings and actors) from an extensive social media dataset. In addition, we sought to investigate the differences between stigma phenotypes with respect to more granular ecological factors. We propose the following research questions (RQs):

    1. What stigma phenotypes (defined by stigma mechanism, substance, setting, and actors) are reflected in social media data?
    2. What additional ecological factors might influence these stigma phenotypes?

    The identification of stigma phenotypes offers valuable insights in guiding the design and development of targeted interventions that address the specific needs and challenges faced by different groups experiencing substance use stigma. By leveraging these phenotypes, targeted interventions can acknowledge the heterogeneity in stigmatizing experiences and deliver support that is contextually relevant to individuals’ lived experiences.

    Data Collection

    We collected a total of 163,662 Reddit posts published between January 1, 2013, and December 31, 2019, from 10 subreddits (, box A) using the Pushshift application programming interface []. Each subreddit focuses on 1 of our 3 substances of interest. Some subreddits (eg, r/OpiatesRecovery, r/leaves, and r/stopdrinking) are recovery focused, whereas the others (eg, r/opiates, r/cannabis, and r/cripplingalcoholism) are not. We only collected thread-initiating posts as they tend to contain richer information than their replies []. More information about the data collection process is discussed in our prior work [].

    Feature Selection

    A total of 14 features (ie, factors) were included in the cluster analysis (, box B). There were 4 groups of features: substances (alcohol, cannabis, and/or opioids), stigma mechanisms (internalized stigma, anticipated stigma, and/or enacted stigma), settings (home, school, work, health care, and/or leisure), and actors (family, partners, and/or friends). The settings refer to both physical and conceptual settings; for example, home refers to both the presence or absence of the physical space and the idea of home. As such, if an individual mentioned housing insecurity in the passage (eg, being forced to leave their home, which could be important in the context of substance use []), this incident would be captured in the data. Specifically, leisure was defined as recreational situations in which a social element is present or implied. Each feature could take 1 of 2 values: 0 (absent) or 1 (present).

    Feature Engineering

    We used NLP methods to develop ML classifiers [,] that predicted the presence of each variable. We then used the classifiers to generate predictions on unseen data to be used for subsequent analyses. The feature engineering pipeline consisted of 2 main parts: content analysis (, box C) and model development (, box D). We conducted 2 phases of content analysis that corresponded to 2 sets of ML models, each serving as a foundation to derive different features necessary for the subsequent cluster analysis ().

    Figure 2. Feature engineering flowchart. BERT: bidirectional encoder representations from transformers; MLP: multilayer perceptron.

    The phase 1 annotated dataset (n=2214 posts) was used to train models that predict the presence versus absence of the substances and stigma mechanisms [], referred to as M1 models. The posts in this dataset were sampled using the keyword sampling approach described by Chen et al [] to select posts that likely contained stigma. Posts were annotated with substances and stigma mechanisms. Further details on the operationalization of the stigma mechanisms are provided in .

    All the M1 models involved fine-tuning a pretrained RoBERTa model []. As stigma-related information is often not explicitly stated in text and requires interpretation beyond surface-level content, we incorporated an additional multilayer perceptron into the M1 models. The multilayer perceptron leveraged a variety of features, including term frequency–inverse document frequency weighted n-grams, the National Research Council Canada Emotion Intensity Lexicon [], the WordNet-Affect Lexicon [], Linguistic Inquiry and Word Count features [], and other handcrafted features []. We report the F1-score as the primary evaluation metric for all models because it balances precision and recall, which is appropriate given that we do not have a strong preference between the 2 metrics. M1 substance models achieved an average F1-score of 0.96 (SD 0.01), whereas M1 stigma models achieved an average F1-score of 0.80 (SD 0.06). Further details on M1 model design, development, and evaluation can be found in our prior work [].

    In phase 2, we sought to identify a wider range of phenomena, including ecological features such as settings and actors. The phase 2 annotated dataset (n=748 posts) included 496 posts from the phase 1 annotated dataset and 252 posts added through quota sampling involving a balanced representation of each substance and stigma type to enrich the representation of stigma within the dataset. This dataset was used to develop classifiers that predicted settings and actors, referred to as M2 models. M2 models used only transformer-based architectures—either bidirectional encoder representations from transformers (BERT) or RoBERTa. To address challenges such as limited training data size and imbalanced data, we implemented the BERTprepend [] data augmentation method on the training set. We then fine-tuned pretrained BERT and RoBERTa models [,] on the augmented dataset and selected the better-performing model for each feature. BERT achieved better performance for home, leisure, work, health care, and friends, and RoBERTa was better at predicting school, family, and partners. The M2 BERT and RoBERTa models achieved an average F1-score of 0.83 (SD 0.03) and 0.81 (SD 0.16), respectively, across the held-out folds of 5-fold cross-validation. presents a summary of the model architectures, predicted features, and model performances.

    Identifying Phenotypes Through Cluster Analysis

    As most collected posts did not contain stigma, we filtered the cluster analysis dataset to retain only stigma-positive posts, ensuring that the analyses were exclusively focused on stigma-related content. Once the features were derived, we restructured the dataset from post level to author level, aggregating the values of each feature across all posts written by the same person (, box E). This procedure was performed to focus on understanding the stigma-related experiences of each individual on a holistic level.

    To address RQ 1 (, box F), we used the fuzzy c-means (FCM) clustering algorithm to derive stigma phenotypes from the data []. As we explored the appropriate clustering techniques, we evaluated a variety of methods, including but not limited to centroid-based, hierarchical clustering and fuzzy or soft clustering methods []. Unlike hard clustering methods that assign each case to a single cluster, FCM offers flexibility in handling ambiguous and complex data through partial cluster membership [], making it particularly well suited for the analysis of substance use stigma, which often manifests in layered and nuanced ways.

    With 14 features, we encountered the “curse of dimensionality” [], meaning that an inverse relationship between meaningful differentiation between clusters and the number of features (or dimensions) was observed. To address this problem, we used principal component analysis (PCA) to condense the feature space down to 4 dimensions while preserving >50% of the cumulative explained variance in our data.

    We used a range of validity indexes to determine the optimal number of clusters (c*) []—fuzzy partition coefficient, partition entropy, Calinski-Harabasz index, silhouette score, and Davies-Bouldin index (). The fuzzy partition coefficient and partition entropy favored the smallest value (c*=2), which was not ideal for understanding complex and fuzzy stigma phenotypic patterns. In contrast, the Calinski-Harabasz index, silhouette score, and Davies-Bouldin index metrics, which measure clustering quality based on intercluster separation and intracluster compactness [], were all in favor of c*=7 compared to other numbers. In summary, we used the FCM clustering algorithm to derive 7 stigma phenotypes from a PCA-transformed dataset with 4 principal components reduced from 14 raw features.

    Figure 3. Validity indices for determining the optimal number of clusters c*. Five validity indices (fuzzy partition coefficient [FPC], partition entropy [PE], Calinski-Harabasz index [CH], silhouette score [SS], and Davies-Bouldin index [DB]) evaluated across 2 to 10 clusters to identify the optimal c* for deriving stigma phenotypes.

    Comparing the Phenotypes in Terms of Ecological Variables

    In cluster analysis, it is common to include the dimensions that the researcher considers to be the defining characteristics, or the primary features of interest, as the variables to be clustered upon. Post hoc analyses are performed subsequently to better understand factors that may influence the defining characteristics [].

    In this study, the primary characteristics of interest were the settings and actors that might be involved in stigma-related experiences, and thus, these served as the focus of RQ 1. However, also consistent with an ecological view, human activity is influenced by a myriad of other factors that intersect at different levels. Thus, for RQ 2 (, box G), we sought to identify additional factors that shape substance use stigma experiences at different levels of influence guided by the SEF [,] and compare their relative prominence with respect to the phenotypes ().

    Figure 4. Social ecological framework (SEF) for determinants of substance use stigma at different levels of influence and sample keywords used for keyword-based statistical analysis.

    We used a keyword-based approach to systematically capture ecological variables. The full list of keywords can be found in . We developed keyword lists and then normalized keyword counts by calculating the percentage of sentences containing the keywords, which allowed for fair and meaningful comparisons across posts of varying lengths.

    At the individual level, loneliness and social isolation were related to substance use and stigma [-]. Through content analysis, a systematic method of assigning codes to text segments [], we observed that legal consequences and rehabilitation and treatment were frequent themes in the dataset. For example, individuals can be stigmatized for driving under the influence of a substance, and people may choose to engage in rehabilitation, treatment, or therapy; capturing these could facilitate a more comprehensive view of the challenges that those experiencing substance use stigma might face.

    At the interpersonal level, the actors included family, partners, and friends, which were prominent actors in the dataset and were included in cluster analysis. Interactions with other actors such as coworkers, health care providers, and others (eg, servers, roommates, and barbers) can also play critical a role in the experiences of a stigmatized individual and, thus, were included in the post hoc analyses.

    Behavior settings are physical and conceptual settings in which stigma and substance use experiences take place []. Home, work, school, leisure, and health care are prominent settings that were included in the cluster analysis. It is important to note that the interpersonal variables and behavior settings are often interconnected but do not completely overlap. For example, one can experience stigma at home, but the stigma is not necessarily enacted by family or partners. Mental health care sits at the intersection of the interpersonal level and behavior settings as it covers both the mental health care setting and mental health care providers.

    At the community level, we included the variable community and support groups, which covers both online and offline communities and support groups such as Alcoholics Anonymous. This is an important variable as communities (primarily online communities, referring to subreddits in this dataset) and support groups can help individuals succeed at substance use recovery [,]. At the societal level, legalization of substances is an important factor to consider as individuals who use illicit substances often experience higher levels of stigma []; society itself is also an actor.

    We used statistical tests to examine the differences among the 7 stigma phenotypes regarding these granular variables. As interim multinomial logistic regression results showed minimal to no interaction effects, we independently analyzed differences between the clusters on the granular ecological variables using the nonparametric Kruskal-Wallis test. To account for multiple comparisons, we performed the Dunn post hoc test with Bonferroni adjustment. These methods are ideal for comparing the phenotypes on nonnormally distributed keyword-based variables []. The full set of test statistics can be found in .

    Ethical Considerations

    In this paper, we use synthetic or paraphrased quotes derived from original data to provide examples of key themes in the data. We use synthetic quotes to protect author privacy as direct quotes from online sources could be traced back to their original posts []. As we developed the synthetic quotes, we worked to ensure that the quotes were representative of the raw data and accurately reflected the language, meaning, and connotation of the original content []. This study received ethics approval from the University of Washington Human Subjects Division (STUDY00015737) and the University of Melbourne Human Research Ethics Committee (2023-25512-48127).

    Sample Statistics

    Our sample comprised 10,430 stigma-related posts representing 8627 authors. shows the descriptive statistics of the dataset at both the author and post levels. The numbers reported in the text pertain to the author level.

    illustrates the distribution of features in each stigma phenotype, with darker cells indicating higher presence and lighter cells representing lower presence. Even though PCA was used to reduce dimensionality, the interpretability of transformed components is conveyed through their alignment with original dimensions. Thus, the reporting of statistics in the characterization of stigma phenotypes was guided by the input features that were used to derive the principal components. The stigma mechanisms and substances were the primary defining characteristics of the clusters, and the setting and actor features contributed to the differentiation between clusters in a more nuanced manner. The phenotypes were as follows:

    1. opioids/alcohol–anticipated stigma–health care (P-0)
    2. alcohol–mixed stigma–more settings and actors (P-1)
    3. alcohol–internalized stigma–few settings and actors (P-2)
    4. cannabis/opioids–enacted stigma–few settings and actors (P-3)
    5. cannabis–mixed stigma–more settings and actors (P-4)
    6. alcohol–enacted stigma–few settings and actors (P-5)
    7. cannabis–internalized stigma–few settings and actors
    Figure 5. Distribution of substances, stigma mechanisms, actors, and settings across 7 identified stigma phenotypes. The heatmap is colored based on the percentage of feature presence in each phenotype, with darker colors indicating stronger presence.

    The 7 phenotypes can be broadly categorized into 2 groups distinguished by shared presence or absence of certain features: those characterized by a single prominent stigma mechanism (P-0, P-2, P-3, P-5, and P-6) and those displaying moderate to high prominence of multiple stigma mechanisms (P-1 and P-4). Among the single-stigma group, there was a distinct separation of the 3 stigma types, with P-2 and P-6 characterized by internalized stigma, P-0 characterized by anticipated stigma, and P-3 and P-5 characterized by enacted stigma.

    Single-Stigma Phenotypes

    Phenotype 2 (P-2; 1363/8627, 15.8% of the authors) and phenotype 6 (P-6; 1152/8627, 13.35% of the authors) were characterized by a high presence of internalized stigma and low presence of anticipated and enacted stigma. The main difference between P-2 and P-6 was the predominant substance—P-2 authors primarily used alcohol (1306/1363, 95.82%), whereas P-6 authors mainly used cannabis (979/1152, 84.98%), with a small proportion using opioids (120/1152, 10.42%). The posts were relatively short (), and settings and actors were rarely mentioned in both phenotypes. The narratives in P-2 and P-6 were usually centered on the posters’ internal feelings and thoughts, without providing much detail about the context:

    I am embarrassed by my drunk actions. I feel like I’m not capable of anything.
    [P-2; internalized stigma; alcohol]

    There were 2 phenotypes with enacted stigma as the distinguishing characteristic (P-3, 1037/8627, 12.02% of the authors and P-5, 1287/8627, 14.92% of the authors). P-5 was characterized by alcohol use (1267/1287, 98.45%), whereas P-3 was mainly associated with cannabis use (698/1037, 67.31%), with some authors (189/1037, 18.23%) reporting opioid use. P-3 and P-5 also differed in terms of the involvement of ecological features. Settings and actors such as family, friends, partners, home, and leisure were common themes in P-5; however, the presence of settings and actors was lower in P-3, except for school. In both enacted stigma phenotypes, it was common for the narratives to center on specific situations, with family and friends being frequently mentioned:

    My wife caught me hung over and we had a huge fight at home. She said that she was disappointed in me, and it really hurts.
    [P-5; enacted stigma; alcohol]

    Phenotype 0 (P-0; 1217/8627, 14.11% of the authors) was the only phenotype in which anticipated stigma was the leading stigma mechanism (1051/1217, 86.36%). Internalized stigma and enacted stigma were also experienced by some individuals but to a lesser extent. The substances used by P-0 authors varied, with 58.09% (707/1217) reporting opioid use, 36.32% (442/1217) reporting alcohol use, and 12.08% (147/1217) reporting cannabis use. Most settings and actors were moderately common, except for school and leisure.

    Notably, P-0 was the only phenotype in which health care was the most prominent setting (647/1217, 53.16%). In many cases, anticipated stigma and health care coexisted without being directly related; however, there were scenarios in which the connections between the 2 features were evident. Some individuals felt the need to seek help from therapists because they hid their substance use problems from people around them, and some others anticipated stigma from health care providers:

    I need to talk to a therapist about my situation because there’s no one else I can talk to. My wife and my family can’t find out that I’m using again.
    [P-0; anticipated stigma; health care]

    How do I get my Dr to prescribe more pain killers without me appearing like a drug seeker?
    [P-0; anticipated stigma; health care]

    Mixed-Stigma Phenotypes

    There were 2 phenotypes in which authors experienced multiple stigma mechanisms. Phenotype 1 (P-1; 1418/8627, 16.44% of the authors) was characterized by alcohol use (1389/1418, 97.95%). In P-1, a total of 74.61% (1058/1418) of the authors mentioned internalized stigma, 46.26% (656/1418) mentioned anticipated stigma, and 40.9% (580/1418) mentioned enacted stigma. Phenotype 4 (P-4; 1153/8627, 13.37%) was characterized by cannabis use (1103/1153, 95.66%). In total, 66.78% (770/1153) of P-4 authors discussed internalized stigma, 50.65% (584/1153) mentioned anticipated stigma, and 21.6% (249/1153) discussed enacted stigma. Narratives in P-1 and P-4 were lengthier (P-1: mean 381, SD 277 words; P-4: mean 433, SD 351 words) and more likely to involve settings and actors. The interconnection between different stigma mechanisms was evident in P-1 and P-4 posts. For example, many authors discussed feelings of internalized stigma and past experiences of enacted stigma:

    How do you all deal with the constant feeling of shame? I keep replaying what happened the other day: I got drunk, blacked out, and ended up vomiting in my friend’s car. I could tell my friend was judging me, and I totally deserve it. I feel so guilty and ashamed, and I can’t stop thinking about it. I really want to quit drinking.
    [P-1; alcohol; enacted stigma; internalized stigma; friends]

    In addition, there were notable differences between phenotypes characterized by different substances. In the internalized stigma–only, enacted stigma–only, and mixed-stigma groups, the school setting was consistently more prominent in the cannabis phenotypes (P-6, P-3, and P-4) compared to the alcohol phenotypes (P-2, P-5, and P-1). Although not many authors explicitly discussed incidents occurring at school, many mentioned that they began smoking cannabis while they were students. Conversely, the leisure setting was consistently more prominent in the alcohol phenotypes than in their cannabis and opioid counterparts. Authors frequently referred to leisure settings to provide context for their stories, but there were also instances in which they discussed stigma-related challenges encountered in leisure contexts:

    I’m excited to attend my friend’s wedding, but I’m worried about what I should say when they offer me drinks. None of them knows that I am an alcoholic and have been trying to stay sober.
    [P-1; alcohol; anticipated stigma; leisure]

    Comparing the Phenotypes in Terms of Ecological Variables

    We conducted Kruskal-Wallis and Dunn post hoc tests with Bonferroni correction to compare and analyze the phenotypes with respect to granular ecological variables. In this section, we focus on the most meaningful comparisons, which are shown in . The unadjusted and adjusted P values for the comparisons between each combination of phenotypes can be found in .

    aP-0 to P-6 denote the stigma phenotypes derived from cluster analysis. See text above for pattern summaries.

    bOther phenotypes refers to the set of phenotypes not explicitly listed on the left side of the comparison. For example, in P-1 and P-4>other phenotypes, other phenotypes refers to P-0, P-2, P-3, P-5, and P-6.

    In , we observe that, at the individual level, the mixed-stigma phenotypes (P-1 and P-4) exhibited significantly higher levels of loneliness and social isolation than other phenotypes (Table S1 in ). The notation P-1 and P-4>other phenotypes indicates that phenotype 1 was significantly greater with respect to this variable when individually compared to the other phenotypes; it does not imply that P-1 and P-4 are significantly different from each other. Rehabilitation and treatment was highest in P-0—characterized by opioid and alcohol use, anticipated stigma, and health care—followed by 2 other alcohol phenotypes, P-1 and P-5 (Table S2 in ). Legal consequences were notably higher in P-3 (Table S3 in ), which is characterized by cannabis and opioid use, enacted stigma, and relatively low presence of the settings and actors studied:

    I got pulled over a couple days ago. The cops thought I was high, but I was completely sober. Then they searched me without even asking for my permission.
    [P-3; legal consequences]

    At the interpersonal level, coworkers was significantly higher in P-1 (alcohol; mixed stigma) than in other phenotypes (Table S4 in ). Physical health care providers were mentioned more in P-0, where health care was the most prominent setting (Table S5 in ). Others were most frequently mentioned in P-1, followed by P-4 (cannabis; mixed stigma) and P-5 (alcohol; enacted stigma; Table S6 in ). P-1, P-4, and P-5 were phenotypes with higher presence of actors in general. The behavior setting mental health care was more prominent in P-0, P-1, and P-4 (Table S7 in ).

    At the community level, P-1 authors mentioned community and support groups more frequently than authors in other phenotypes (Table S8 in ). There was a strong sense of (online) community among P-1 authors:

    34 days sober. I could really use some words of encouragement to support me through the process, and I will stay active in this thread for accountability. Thanks everyone.
    [P-1; alcohol; community and support groups]

    Finally, at the societal level, society was mentioned more by P-3 and P-1 authors compared to authors in some but not all other phenotypes (P-2, P-5, and P-6; Table S9 in ). P-3 authors, characterized by opioid or cannabis use, discussed legalization much more than those in other groups (Table S10 in ).

    Principal Findings

    Using the FCM clustering algorithm, we derived 7 stigma phenotypes based on posts containing stigma related to 3 substances. Stigma mechanisms and substances were the key determinants of the phenotypes, and settings and actors influenced the differentiation between clusters in a more subtle way. The 7 stigma phenotypes can be categorized into 4 groups: internalized stigma–only group (P-2 and P-6), anticipated stigma group (P-0), enacted stigma–only group (P-3 and P-5), and mixed-stigma group (P-1 and P-4). This distinction highlights significant differences in the manifestations of the stigma mechanisms individually and in concert.

    The narratives in the internalized stigma–only phenotypes were characterized by a focus on internal feelings, with few references to contextual factors. In contrast, the narratives in the enacted and anticipated stigma phenotypes usually involved more settings and actors, which exemplifies the inherently interpersonal nature of these 2 stigma mechanisms [].

    We observed a complex connection among anticipated stigma, health care, and opioid use in the anticipated stigma phenotype (P-0), which was the only phenotype where anticipated stigma, opioid use, and health care were significantly more common than other stigma types, substances, and settings, respectively. Health care providers often exhibit negative attitudes toward patients with substance use disorders []; consequently, individuals with substance use problems frequently experience anticipated stigma in health care settings, reducing their willingness to seek help from health care professionals [,]. This pattern is particularly pronounced among opioid users, exemplified by behaviors such as attempting to hide their substance use history and avoiding health care interactions []. Moreover, the high prevalence of the mental health care setting in this phenotype is likely related to anticipated stigma—individuals often seek or consider seeking help from mental health care providers because they find it difficult to discuss their issues with people around them.

    In the mixed-stigma phenotypes (P-1 and P-4), the connections between stigma mechanisms were evident. We observed that past experiences of enacted stigma can lead to or reinforce anticipated and internalized stigma []. This is in line with the progressive model of self-stigma [], which posits 4 stages that eventually lead to diminished self-esteem. This first stage is being aware of the stereotypes, which can be caused by incidents of enacted stigma and may result in anticipated stigma. Individuals may then agree with the stereotypes and apply the stereotypes to themselves, which aligns with internalized stigma. Finally, the internalized stigma that individuals experience may lead to lower self-esteem.

    In addition, significantly higher levels of loneliness and social isolation were observed in the mixed-stigma phenotypes. While the underlying mechanisms behind this phenomenon remain unclear, several possibilities can be suggested. In some cases, individuals may isolate themselves voluntarily to avoid social interactions and social stigma []. Moreover, loneliness and social isolation may also reinforce both anticipated and internalized stigma as individuals continually worry about how others perceive and react to them []. There was also a high presence of the mental health care setting in the mixed-stigma group. Given these results, interventions targeting individuals who experience multiple forms of stigma should address the individuals’ feelings of loneliness and social isolation and needs for therapy.

    Moreover, substantial differences were evident among the substances studied. The leisure setting was more prominent in alcohol phenotypes than in their cannabis and opioid counterparts. Individuals recovering from alcohol use may feel social pressure to drink and experience stigma in leisure contexts as they attempt to hide their substance-related problems. Therefore, interventions for alcohol users could focus on stigma reduction in social and leisure contexts. The school setting was more prominent in cannabis phenotypes. Previous research has demonstrated that cannabis use is notably prevalent among middle and high school students [,], and exposure to cannabis use at school increases the likelihood of students’ own cannabis use, but the same pattern does not hold for alcohol []. Our finding further solidifies the necessity for targeted interventions designed for school settings [].

    Furthermore, there were distinctive ways in which specific phenotypes stood out. P-0, characterized by opioid and alcohol use, was the only cluster in which health care was the most prominent setting. It was common for P-0 authors to mention chronic pain conditions and the use of opioids for pain management []. In addition, there were also cases in which the authors engaged with physical health care providers due to consequences of opioid or alcohol use, such as overdose, severe hangovers, or driving under the influence accidents. These results suggest that interventions in the health care scope should address not only the consequences but also the underlying circumstances of substance use.

    In comparison to all other phenotypes, the role of community and support groups was highly emphasized in P-1, which was characterized by alcohol and mixed-stigma mechanisms. P-1 individuals had a strong sense of (online) community—they sought social support from each other and provided support when they could. They also used the online community to hold themselves accountable. In addition, offline support groups such as Alcoholics Anonymous were often mentioned in P-1 narratives. Congruent with our own prior work, individuals expressed concerns and uncertainties about attending offline support groups, shared both positive and negative experiences and insights, encouraged others to join, or discussed why support groups did not work well for them []. These findings suggest that online communities such as Reddit can serve as valuable resources for individuals with substance use stigma problems. Offline support groups can also provide support and offer a structured environment for recovery, but they may not be suitable for everyone. While P-3 and P-5 were both characterized by enacted stigma, the involvement of actors and settings was notably lower in P-3 (cannabis and opioids) than in P-5 (alcohol). This discrepancy might be largely attributed to the prevalence of legal consequences, legalization, and society in P-3. Some individuals may express concerns regarding the legal consequences of their substance use behaviors. In other cases, legal consequences can manifest as a form of enacted stigma. For example, individuals may feel that they were unfairly stopped or searched due to their substance use history or appearing to be under the influence. At the societal level, the legalization of a substance can influence the public’s attitudes toward the normalization of its use []. Individuals in P-3 actively engaged in discussions about cannabis legalization, covering a range of topics. They expressed their opinions on government policies, shared troubles they faced due to the legal status of the substance they used, and discussed how drug laws disproportionately affect ethnic minority groups. These findings highlight the need for interventions to consider the impacts of legal consequences, substance legalization, society, and the stigma associated with substance use.

    Strengths and Limitations

    This research has the following contributions and strengths. This study examined the manifestations of substance use–related stigma in a large-scale dataset. Unlike many studies that focus on a specific subgroup of individuals who either use a particular substance or experience a specific type of stigma [,], this research adopted a holistic approach to identify stigma phenotypes in a large dataset by including users of different substances and their experiences with different stigma mechanisms. Furthermore, even though NLP and ML techniques [] and the SEF model [,] have been used separately in previous studies to explore health care–related topics, this research introduced a novel methodology that combined all 3. This combined approach ensured the scalability of the research by facilitating the understanding and analysis of a volume of data at a level of granularity that is difficult to achieve with qualitative and survey-based methods.

    The limitations of this study are related to the nature of the dataset and sampling bias. The analysis was limited to Reddit data from 10 subreddits, which may not represent broader populations who experience substance use stigma, particularly those who are less engaged in social media. The percentage of authors who mentioned opioid use was significantly lower than the percentage of authors who mentioned the other 2 substances of interest, which could introduce bias in the clustering results. In addition, the results of this study largely depend on what the posters chose to disclose and how much detail they chose to include. In general, we found that phenotypes with longer average post lengths (P-0, P-1, and P-4) tended to have a higher presence of stigma, behavior settings, and actors. In phenotypes with shorter posts (P-2 and P-6), these factors were mostly absent. The relationship among post length, detail, and presence of features was subtle and complex. On the one hand, individuals who wrote longer, more detailed posts may have encountered problems in multiple aspects of their lives; thus, their discussions revolved around multiple settings, actors, and stigma mechanisms. On the other hand, they might simply feel a stronger urge of self-disclosure or have a detail-oriented writing style.

    Conclusions

    In this study, we introduced a novel combination of NLP, ML, and statistical techniques to examine narratives containing stigma related to substance use from a social ecological perspective. We identified 7 phenotypes from large-scale social media data about substance use and stigma. These phenotypes revealed distinct patterns in terms of stigma mechanisms, substances used, settings and actors involved, and the role of ecological factors across different levels of our framework. The findings of this study provide a framework for understanding stigma as a multidimensional and context-dependent phenomenon. The valuable insights from this research could inform the design and development of interventions targeting different stigma contexts.

  • Competition Bureau discontinues algorithmic pricing investigation and issues guidance | Canada | Global law firm

    Competition Bureau discontinues algorithmic pricing investigation and issues guidance | Canada | Global law firm

    The Competition Bureau (the Bureau) just discontinued its inquiry into the use of revenue management (algorithmic) pricing software for rental housing in Canada. The Bureau’s position statement provides useful guidance to help businesses understand how their use of algorithmic pricing will be treated under the Competition Act (the Act) – not only in the context of property rental markets, but any markets where these tools are being used.


    The investigation

    The Bureau commenced its inquiry in January 2025 in response to public concerns about housing affordability and whether landlords were colluding on rental prices by using algorithmic pricing software. Algorithmic pricing software combines multiple data points, including users’ competitively sensitive data, and supply and demand data, to calculate recommended pricing. 

    In this case, the Bureau investigated whether landlords and property managers used algorithmic pricing tools supplied by RealPage Canada, Inc. and Yardi Canada, Ltd. in a manner that resulted in tenants paying higher rents than would otherwise have been the case. The concern with these types of pricing tools is they allow users to set rents based on non-public, competitively sensitive data. The Bureau considered whether this behaviour raised concerns under both the civil and criminal provisions of the Act

    The Bureau’s investigation focused on: 

    • Abuse of dominance: Whether RealPage and Yardi were engaging in practices contrary to the abuse of dominance provisions of the Act that were intended to harm or in fact had harmed competition in the rental housing market. The specific practices investigated include: the collection and comingling of non-public, competitively sensitive information from landlords, the use of pricing algorithms to artificially inflate price recommendations, and the extent to which software makes it easier to comply with those recommendations or provides disincentives not to do so. 
    • Anticompetitive collaboration: Whether RealPage or Yardi entered into anticompetitive agreements or arrangements. 

    The Bureau concluded that, because the use of revenue management software is not widespread in Canada, there was insufficient evidence to suggest either abuse of dominance or anticompetitive collaboration. 

    However, the Bureau has suggested it will continue to monitor market participants’ behaviour in the rental housing market and may reopen its inquiry if it obtains further information. 

    In the US, the Department of Justice, in ongoing litigation, sued RealPage and several landlords in August 2024, alleging that its software facilitates price fixing. 

    Guidance

    The Bureau indicated that, while its inquiry did not find a contravention of the Act, it “remains concerned about the use of algorithmic pricing tools in the Canadian rental housing market and their potential to harm competition.” 

    The Bureau has recommended that landlords review their practices and software providers review their product offerings to ensure they do not contravene the Act. Specifically, the Bureau recommends they ask themselves the following questions: 

    • Does the revenue management software use non-public or competitively sensitive information from competitors? This may include a variety of factors relevant to landlord decision-making, including lease terms, rents, vacancy data, and rent concessions. 
    • Does the software affect a landlord’s ability to reject or override price recommendations, or impose penalties for doing so? The Bureau is concerned with how easy it is for landlords to accept and implement pricing recommendations, and whether the software creates an environment conducive to price coordination.
    • Does the software artificially inflate price recommendations—e.g., by setting a minimum price floor or limiting available inventory to create an artificial lack of supply?
    • Does the software disclose non-public, commercially sensitive information about competitors? 

    Key takeaways

    While this case focussed on the use of algorithmic pricing in the rental housing market, it clearly suggests that companies should expect that the Bureau is actively monitoring the use of algorithmic pricing tools in other markets.

    Companies seeking to provide or use algorithmic pricing or similar revenue management tools should carefully review their practices from a competition law compliance perspective. In this regard, the Bureau’s guidance provides a useful framework that can assist companies in all markets where algorithmic pricing tools are used with assessing whether their use of these types of tools could raise serious compliance issues under the Act.
