Towards Cross-lingual Social Event Detection with Hybrid Knowledge Distillation

Recently published graph neural networks (GNNs) show promising performance at social event detection tasks. However, most studies are oriented toward monolingual data in languages with abundant training samples. This has left the common lesser-spoken languages relatively unexplored. Thus, in this work, we present a GNN-based framework that integrates cross-lingual word embeddings into the process of graph knowledge distillation for detecting events in low-resource language data streams. To achieve this, a novel cross-lingual knowledge distillation framework, called CLKD, exploits prior knowledge learned from similar threads in English to make up for the paucity of annotated data. Specifically, to extract sufficient useful knowledge, we propose a hybrid distillation method that consists of both feature-wise and relation-wise information. To transfer both kinds of knowledge in an effective way, we add a cross-lingual module in the feature-wise distillation to eliminate the language gap and selectively choose beneficial relations in the relation-wise distillation to avoid distraction caused by teachers’ misjudgments. Our proposed CLKD framework also adopts different configurations to suit both offline and online situations. Experiments on real-world datasets show that the framework is highly effective at detection in languages where training samples are scarce.

‘Am I being unreasonable to vaccinate my kids against my ex’s wishes?’ – A corpus linguistic exploration of conflict in vaccination discussions on Mumsnet Talk’s AIBU forum

Online parenting forums are popular sources of information about childhood vaccinations, but vaccination discussions, especially online, are often polarised and polarising (Jenkins & Moreno 2020). This can have very real implications for ultimate vaccination decisions (Al-Hasan et al., 2021). Among the most visited parenting forums in the UK is Mumsnet Talk, hosted on the parenting website Mumsnet, which has a reputation for being straight-talking and combative. This supposedly applies particularly to its most popular Talk Topic, Am I being unreasonable?’ (AIBU), which also includes numerous threads related to vaccinations.In this paper we combine corpus-based methods with qualitative discourse analysis to examine over 6-million words of vaccination-related discussions on 895 threads on AIBU from the inception of Mumsnet in 2000 to May 2021. We provide evidence of a greater presence of confrontation-related language in these threads when compared with similar threads not on AIBU, zooming in on nine keywords that can be used as insults (e.g. ‘idiot’ and ‘bitch’). The use of these keywords reveals the multiple types of conflict at play, including between people with opposing and similar vaccine stances. While some insults are directed at each other within the forum, the majority are directed at external third parties, often the protagonists at the heart of offline conflicts detailed in the original post of an AIBU thread. We show that, although these insults perform impoliteness towards external third parties potentially perpetuating conflict that predates any posting on the forum, they simultaneously have a supportive and community enhancing function within the threads. We reflect on the implications of our findings for the role of AIBU as a point of reference and site of interaction for parents facing vaccination-related issues and decisions.

Recommendations for a balanced approach to supporting academic integrity: perspectives from a survey of students, faculty, and tutors

Maintaining academic integrity is a growing concern for higher education, increasingly so due to the pivot to remote learning in 2020 caused by the COVID-19 pandemic. We canvassed students, faculty, and tutors at an online Canadian university about their perspectives on academic integrity and misconduct. The survey asked how the university could improve policies concerning issues of academic integrity, how faculty and tutors handled cases of misconduct, about satisfaction with how academic violations were treated, and about the role of students, faculty, and tutors in encouraging academic integrity. As well, we collected suggestions from respondents for reducing cheating, addressing academic misconduct, and general ideas about academic integrity. The distinction between misconduct and integrity was not always clear in their comments. We received responses from 228 students and 73 faculty and tutors, generating hundreds of comments. In this paper we focus only on the answers to open-ended questions. Using content analysis, we categorized the replies into similar threads. After multiple iterations of analysis, we extracted three general recommendation groupings: Policy and Procedures, Compliance and Commitment, and Resources. Based on respondents’ views, we propose a balanced approach to supporting academic integrity. Although we conducted the study pre-COVID-19, the recommendations apply to current and future academic integrity practices in our context and beyond.

Promising Practices and Emerging Ideas in Academic Integrity Policy Development

Recently, Athabasca University canvassed faculty, tutors, and students about their perspectives on academic integrity. Responses to open-ended questions were received from 102 faculty and tutors and 146 students, generating hundreds of comments. The survey asked how Athabasca University could improve its policies concerning issues of academic integrity, about satisfaction with how academic violations were treated, on the role of faculty and tutors in encouraging academic integrity, and on how faculty and tutors handled cases of misconduct. As well, we collected suggestions from faculty, tutors, and students for reducing cheating, increasing academic integrity, and other ideas about academic integrity in general. Using content analysis, we categorized these open-ended replies into similar threads. Five general recommendation groupings were extracted: policy and procedures, compliance and commitment, resources, plagiarism detection software, and other. The proposed presentation will focus on two sets of recommendations: policy and procedures and plagiarism detection software. We believe that our work meets the criteria for the call for papers because we are learning from our faculty, tutors and students and are interested in sharing their insights. Although we conducted the study pre-COVID-19, we think the recommendations apply now as much as they did then, and will continue to be useful into the future.

Пеплы 2017 года с вулканов Ключевского и Камбального: сравнительный минералогогеохимический анализ

The results of the mineralogical and geochemical study of the ash of the Klyuchevskoy and Kambalnyy volcanoes located in different geological conditions (Klyuchevskoy – Central Kamchatskaya Depression, Kambalnyy - Southeast end Eastern Kamchatka Volcanic Ridge) were obtained in 2017, and allowed making following conclusions. The investigated ashes differ somewhat in chemical composition: the Klyuchevskoy volcano ash is close to andesibasalts, but that from Kambalnyy is close to andesites. According to the normative-mineral composition, they are composed of 65–87% basic plagioclases, 3–22% quartz, 6.5–14% Mg-Fe-Ca silicates (olivine, pyroxene, probably hornblende). In this case, the ashes from the volcano Kambalnyy are characterized by more acidic composition of plagioclase and higher content of quartz. The accessory minerals found in the ashes are presented by spinels (Ulviya magnetite, magnetite, and chromite), ilmenite, rutile, apatite, zircon, pyrite and native metallic-phase (Al, Cu, Fe). Pelitic (silty) fractions are enriched in quartz, but impoverished in Mg-Fe-Ca silicates. As a small admixture in the ash of the Cumulus volcano, titanite, andradite, kaolinite and gypsum are inherently resurgent. The fact of detecting the filamentous forms of abiogenic condensed organopolymer substance of CNO composition in the investigated ashes is of particular importance. It should be noted that, according to the isotope composition of carbon, these formations are identical to similar threads and particles identified in products of modern volcanism in the Kamchatka-Philippine island arc megabelt. Moreover, the analysis showed the presence in the ashes of the Kliuchevskoy and Kambalnyy volcanoes of the carbon substance, which carbon isotopic composition practically coincides with that in the organic filaments. Ashes contain 50 microelements divided into five groups: alkaline and alkaline earth, hydrolyzed, lanthanides, chalcoceridophiles, semi- and non-metals. The analysis leads to the conclusion that the predominantly plagioclase containing ash from both volcanoes show a 75% geochemical similarity to the deep source matter. According to the shape of the curves of chondritotropic concentrations of lanthanides, the ashes from both volcanoes are close to the basaltic lavas of TTI-50. The insignificance of the Eu anomaly on the most curves and the apparent moderate differentiation of the lanthanides indicate that the fractionation of plagioclases in the primary melts and the significant realization of the fractionation of olivine and pyroxenes are weak. Based on the granulometric and morphological homogeneity of particles and the presence of a significant content of fresh volcanic glass in ash from both volcanoes, it can be assumed that in both cases the ashes were predominantly or largely melt-formed, and primarily associated with deep magmatic chambers. It is supposed that the process of slow rise of magmatic melts with their fractionation and gravitational stratification into the lower Mg-Fe-silicate and upper aluminosilicate parts took place. Last eruption of the aluminosilicate substrate occurred in the ash form. Because of the viscosity and tendency to quick solidification, aluminum silicate magmatic magma plugged the channel thus preventing the eruption of the lava Hawaiian type.

Plurality in the Fabric of International Courts and Tribunals: The Threads of a Managerial Approach

Starting from the observation that there has long been - and continues to be - a preference for a plurality of international courts and tribunals, this article explores the emerging threads of a managerial approach in the fabric of international dispute settlement due to the increased number of fora in recent years. It argues that, while plurality remains the choice, both judges and states are actors in efforts to order this plurality as the need for judicial awareness and tools to organize jurisdiction has become more acute. In particular, judicial actors have woven common normative threads through various communicative practices and their approach to matters of procedure. Further, procedural mechanisms are being used to a greater extent to mitigate the risks of overlapping jurisdiction and parallel proceedings. In this respect, international economic law is serving as a laboratory for the development of these mechanisms. They include, among others, adapted versions of 'lis pendens', 'connexite' or fork-in-the-road provisions. That said, similar threads of a managerial approach can be seen to be emerging beyond international economic law. Further reflection is needed on a creative means for ensuring coordination and coherence without compromising the preference for plurality.

Correlation between the sub-structure parameters and the manufacturing technologies of metal threads in historical textiles using X-ray line profile analysis

Micro-structure can talk when documentation is missing. In ancient Roman or medieval periods, kings, queens, or just rich people decorated their clothes or even their horse covers richly with miniature jewels or metal threads. The origin or the fabrication techniques of these ancient threads is often unknown. Thirteen thread samples made of gold or gilt silver manufactured during the last sixteen hundred years are investigated for the micro-structure in terms of dislocation density, crystallite size, and planar defects. In a few cases, these features are compared with sub-structure of similar metallic threads prepared in modern, twentieth century workshops. The sub-structure is determined by X-ray line profile analysis, using high resolution diffractograms with negligible instrumental broadening. On the basis of the sub-structure parameters, we attempt to assess the metal-threads manufacturing procedures on samples stemming from the fourth century A.D. until now.

Silk production from tarantula feet questioned

As with all spiders, tarantulas spin silk from specialized structures in the abdomen called spinnerets, which are key features unique to the group. Recently Gorb et al. reported that the zebra tarantula Aphonopelma seemanni also secretes silk from its feet, which might improve its ability to climb on vertical surfaces. Here we show that when the spinnerets are experimentally sealed, the zebra tarantula cannot secrete silk or similar threads, disagreeing with previous reports by Gorb et al.. Additional evidence also disagrees with leg secretion of silk.

Fee-for-service or donation? Hungarian perspectives on informal payment for health care

Informal payments are known to be widespread in the post-communist health care systems of Central and Eastern Europe. However, their role and nature remains contentious with the debate characterized by much polemic. This paper aims to make sense of this debate by reviewing and summarizing the main arguments of the theoretical debate in Hungary. The review examines the possible causes of informal payment, the motivation of the actors involved and the impact of informal payment on system performance, focusing on efficiency and equity. The lines of arguments are summarized in two contrasting hypotheses, which envisage informal payment as either a donation or a fee-for-service. Evidence pertaining to the scale of informal payments and the motivation of patients are reviewed, but found to be inconclusive to verify the hypotheses. Although focused on Hungary, accounts from other countries facing informal payments show similar threads of discussion and dilemmas. These theories should be tested further using evidence from existing studies and new empirical research, since the validity of the gratitude payment concept is a central dilemma of effective policy making in the area. To orient future research, a possible agenda is outlined, which links evidence to be obtained to the defining features of gratitude payments.

Polycystic Ovary Syndrome: A Connection to Insufficient Milk Supply?

Despite advances in lactation skills and knowledge, insufficient milk production still continues to mystify mothers and lactation consultants alike. Based on 3 cases with similar threads, a connection is proposed between polycystic ovary syndrome (PCOS) and insufficient milk supply. Described are the etiology and possible symptoms of PCOS such as amenorrhea/oligomenorrhea, hirsutism, obesity, infertility, persistent acne, ovarian cysts, elevated triglycerides, and adult-onset diabetes, along with possible pathological interference with mammogenesis, lactogenesis, and galactopoiesis. Clinical suggestions include guidelines for screening mothers and careful monitoring of babies at risk. Further research is necessary to confirm the proposed association and to develop therapies with the potential to improve lactation success.

A summary of the agricultural issues raised at the conference

The conference ranged widely over the whole field of diffuse pollution and agriculture with many papers bridging the artificial divide, unavoidably created by the programming, between agricultural, catchment and urban issues. However, for the purposes of this summary, the papers can be divided into groups on the basis of the pollutant problem addressed. Three main themes appear: nitrogen, phosphorus and pesticides. This summary will attempt to examine the issues raised in these themes, the current state of knowledge in each of them and to identify any similar threads which run through all of them.

Nuclear Bodies of Stage 6 Oocytes ofRana temporariaContain Nucleolar and Coiled Body Proteins

The genetically inactive stage 6 oocyte nuclei ofRana temporariacontain certain nuclear bodies that label with nucleolus-specific and coiled body (CB)-specific antibodies. We designate them multicomponent bodies (MCBs) to reflect their mixed composition. Morphologically, each MCB contains five distinct zones: zone I composed of electron-dense fibrils similar to the dense fibrillar component (DFC) of the typical eukaryotic nucleoli; zone II resembled the fibrillar material of the inactive agranular nucleoli of stage 6 oocytes; zone III consisted of fine filamentous material corresponding to the fibrillar center (FC) of lower electron density seen in the typical nucleoli; and zones IV and V contained packed coiled threads typical of CBs. Of these, zone IV was seen in the interior of MCBs and contained tightly packed coiled threads (20 nm thick), while zone V occurred at the periphery and consisted of similar threads but loosely packed and electron dense. The material of both zones IV and V resembled that of CBs. To determine the composition of these zones, we extracted oocytes with a buffer that removes chromatin and most of the soluble proteins and processed them for immunogold labeling with a variety of antibodies. Anti-p80 coilin antibody predominantly labeled zone IV and, to a lesser extent, zone V. Anti-snRNP antibody also showed a similar labeling pattern. Anti-fibrillarin antibody predominantly labeled zone I and to a lesser extent zones IV and V. Anti-B23 antibody labeled all zones. These observations suggest that MCBs contain both nucleolar and CB material. We postulate that MCBs represent storage structures which provide material needed for the early stage of embryogenesis. The demonstration of MCBs further supports the close interrelationship between nucleoli and CBs.

Combas & Co. or the Figure and the Great Divide

The young painter, Robert Combas, leader of the 1980s "figuration libre" 'free figuration' movement, is seen here both as representative of stylistic and thematic trends in contemporary French art, and as illustrative, through the unfolding of his career, of the object "painting" and its sociology in contemporary France. Examined are: first, the "Postmodern convergence" of figurative, indeed narrative art, with the collapse of the "great divide" between elite and popular art forms; and second, traits such as hypertrophic verbal paratext, high erotic content, and political stand. Similar threads are followed in the work of a number of other artists, old and young, established or not, female and male—hence the "& Co." of the title. The essay raises, without claiming to solve, a set of sociologically and politically informed questions: What forces have shaped Combas' sensibility and style? What forces have made him a minor celebrity domestically, one that France's awesome cultural apparatus considers worthy of export? What, in the formation of contemporary mentalities and tastes, may account for the parallels found among artists as diverse as Combas, Quardon, Pierre and Gilles, Ben, and Klossowski?

Psychosocial Themes in the Lives of Children of Survivors and Nazis

Abstract Significant work has been done on effects of the Holocaust on the second generation. Research shows there is a link between the parents' trauma and a variety of psychological symptoms in children of survivors. Children of Nazis have also been a topic of psychological and journalistic inquiry. The research suggests that many of these children experience conflict, shame, and personal guilt when dealing with their parents' Nazi past. The much discussed "inability to mourn" has been identified as the central reason for why these children were traumatized. These findings have been central to our awareness of the intergen-erational effects of the Holocaust. There is to date, however, no systematic research that compares the effects on these two groups of descendants. Thus, in an effort to advance research in this area, this study was undertaken to explore similarities between these two groups. Whereas previous studies have focused on the pathological effects of trauma on each group separately, the focus of this study was on comparative coping responses of individuals whose parents were involved in an extreme social injustice. An additional later aim is to study the interpersonal behavior between children of survivors and children of Nazis. The study consisted of interviewing 20 subjects, 10 children of Nazis and 10 children of concentration camp survivors. The former subjects were interviewed by a child of a Nazi (Kuphal), and the latter were interviewed by a child of concentration camp survivors (Weissmark). The interview was de-signed by a neutral party (Giacomo) to generate data by focusing on broad areas. The investigators hypothesized that these areas would yield useful data for comparing the similarities and differences between the two groups of sub-jects. Responses of children of survivors and Nazis revealed similar threads of images and associations to the past that run through their lives. These include: information-seeking, meaning-making, a personal sense of injustice, and re-dressing actions. (Psychology)

Ultrastructure of the neuropil threads in the Alzheimer brain: their dendritic origin and accumulation in the senile plaques

Thread-like structures immunoreactive with paired helical filaments and tau antisera were demonstrated as mesh-works in the neocortices of five brains with Alzheimer-type dementia, but not in those of five normal aged control brains. The ultrastructure of the threads was examined using paired routine electron microscopic ultrathin sections and adjacent 0.4-micron-thick semithin sections, immunostained for beta protein. Outside the beta protein-positive senile plaques, neuropil threads appeared sporadically as small slender neurites, containing either regularly constricted or straight filaments. These neurites often showed dendritic profiles. Similar threads were also seen within the senile plaques. The threads were accumulated in amyloid fibril-rich primitive plaques, but not in amyloid fibril-poor diffuse plaques. The presence of these threads was closely associated with neurofibrillary tangle formation. Our findings suggest that wide-spread change of the neuropil neurites, neuropil threads or curly fibers, both outside and inside of the senile plaques are dendritic in origin and play an important role in the clinical manifestation of dementia.

Cell surface changes during cleavage of newt eggs: scanning electron microscopic studies

Scanning electron microscopic studies were carried out on changes of the cell surface during the first cleavage of eggs of the newt, Cynopus (Triturus) pyrrhogaster. A dense population of elongated microvilli, which initially covered a double line indicating the initial furrow and stress marks running on each side of it, became located inside the pigmented area a little apart from its border with the unpigmented area when this borderline was established. This finding, together with data of carbon marking experiments, indicates that membrane growth occurs not only at the presumptive unpigmented surface, but also in a small portion of the presumptive pigmented area adjoining it. During cleavage within the vitelline membrane, a stable intercellular junction at the border of the pigmented and unpigmented surfaces was formed through the following successive processes: the appearance of individual lamellipodia on the borderline; contact of their apical filopodia with those of the opposite blastomere; contact of the lamellipodial bodies; and complete joining of the whole of the lamellipodia in contact. In cleavage of demembranated eggs, in which there is no chance of contact of lamellipodia of the two blastomeres, each lamellipodium persisted in an isolated state until the onset of the next division. In most cases, many strained or broken threads were seen across the space formed by opening of opposing blastomeres, at their peripheries. These threads were cytoplasmic in nature and showed cell contact. Similar threads were found stretched between blastomeres when the closed furrow was opened in medium containing EGTA.
