    Towards Suicide Prevention from Bipolar Disorder with Temporal Symptom-Aware Multitask Learning

    Full text link
    Bipolar disorder (BD) is closely associated with an increased risk of suicide. However, while the prior work has revealed valuable insight into understanding the behavior of BD patients on social media, little attention has been paid to developing a model that can predict the future suicidality of a BD patient. Therefore, this study proposes a multi-task learning model for predicting the future suicidality of BD patients by jointly learning current symptoms. We build a novel BD dataset clinically validated by psychiatrists, including 14 years of posts on bipolar-related subreddits written by 818 BD patients, along with the annotations of future suicidality and BD symptoms. We also suggest a temporal symptom-aware attention mechanism to determine which symptoms are the most influential for predicting future suicidality over time through a sequence of BD posts. Our experiments demonstrate that the proposed model outperforms the state-of-the-art models in both BD symptom identification and future suicidality prediction tasks. In addition, the proposed temporal symptom-aware attention provides interpretable attention weights, helping clinicians to apprehend BD patients more comprehensively and to provide timely intervention by tracking mental state progression.Comment: KDD 2023 accepte

    An exploration of the attitudes and beliefs of teacher trainers and teacher trainees concerning the use of the L1 in the EFL classroom

    One important conflict within English language teaching methodology is concerning the use or exclusion of learners’ first languages (L1) when learning English. Perspectives on the topic range from those in favour of complete avoidance of the L1 in the EFL classroom, constantly striving for an exclusively L2 classroom to those who believe in the value and learning benefit of allowing and, to some extent, encouraging the use of all manner of languages available to the learner. This thesis conducted interviews and surveys in order to provide an in-depth exploration of the attitudes and beliefs of teacher trainers and teacher trainees in North Rhine Westphalia concerning the use of the L1, as well as other potential languages, in the English language classroom. Although the two groups of participants held many similar attitudes and beliefs concerning L1 use, some significant and interesting differences were found. Teacher trainees showed themselves to be more open concerning the use of the L1 than their more experienced counterparts. It remains, however, unclear what exactly the reason for these differences is. A further aspect which became apparent is how the pressures of language choice and of exclusive L2 instruction in the EFL classroom during observed and examination lessons is felt by teacher trainees. This is potentially adding to the overall burden of the teacher training period in NRW. The thesis concludes that an increase in evidence-based teacher education, concerning not only the aspect of L1 use in the EFL classroom but also many other aspects of language teaching could be prudent in the continued development of well-informed best-practice approaches. This thesis holds the standpoint that complete eradication of the L1 in the EFL classroom is counterproductive to successful language learning. Judicious use of the L1 and the development of a more plurilingusitic attitude to language learning, enabling learners to make use of any available linguistic resources, can offer both learners and teachers helpful scaffolding which can facilitate the successful learning of further languages

    Novel 129Xe Magnetic Resonance Imaging and Spectroscopy Measurements of Pulmonary Gas-Exchange

    Gas-exchange is the primary function of the lungs and involves removing carbon dioxide from the body and exchanging it within the alveoli for inhaled oxygen. Several different pulmonary, cardiac and cardiovascular abnormalities have negative effects on pulmonary gas-exchange. Unfortunately, clinical tests do not always pinpoint the problem; sensitive and specific measurements are needed to probe the individual components participating in gas-exchange for a better understanding of pathophysiology, disease progression and response to therapy. In vivo Xenon-129 gas-exchange magnetic resonance imaging (129Xe gas-exchange MRI) has the potential to overcome these challenges. When participants inhale hyperpolarized 129Xe gas, it has different MR spectral properties as a gas, as it diffuses through the alveolar membrane and as it binds to red-blood-cells. 129Xe MR spectroscopy and imaging provides a way to tease out the different anatomic components of gas-exchange simultaneously and provides spatial information about where abnormalities may occur. In this thesis, I developed and applied 129Xe MR spectroscopy and imaging to measure gas-exchange in the lungs alongside other clinical and imaging measurements. I measured 129Xe gas-exchange in asymptomatic congenital heart disease and in prospective, controlled studies of long-COVID. I also developed mathematical tools to model 129Xe MR signals during acquisition and reconstruction. The insights gained from my work underscore the potential for 129Xe gas-exchange MRI biomarkers towards a better understanding of cardiopulmonary disease. My work also provides a way to generate a deeper imaging and physiologic understanding of gas-exchange in vivo in healthy participants and patients with chronic lung and heart disease

    Innovation in Energy Security and Long-Term Energy Efficiency â…ˇ

    The sustainable development of our planet depends on the use of energy. The increasing world population inevitably causes an increase in the demand for energy, which, on the one hand, threatens us with the potential to encounter a shortage of energy supply, and, on the other hand, causes the deterioration of the environment. Therefore, our task is to reduce this demand through different innovative solutions (i.e., both technological and social). Social marketing and economic policies can also play their role by affecting the behavior of households and companies and by causing behavioral change oriented to energy stewardship, with an overall switch to renewable energy resources. This reprint provides a platform for the exchange of a wide range of ideas, which, ultimately, would facilitate driving societies toward long-term energy efficiency

    Marijuana Cultivation Laws and Admissions for Cannabis Use Disorder in US Substance Abuse Treatment Facilities

    Get PDF
    With approximately 4.4 million Americans addicted to cannabis, it is considered a dominant non-medical drug that is common in the US. The purpose of this study was to investigate the possible contribution of the state laws that allow the cultivation of marijuana to Marijuana Medical (MM) program cardholders on cannabis addiction. This study was conducted to address the issue of the increase in demand for cannabis-related admissions that contribute to an upsurge in the unmet treatment needs. The study is founded on the Ecological Models proposed by Urie. The key research question explored the association between state laws that allow cardholders to cultivate medical marijuana plants and the percent of state CUD admissions reported in the US Treatment Episode Data Set for Admissions (TEDS - A) between 2015 and 2019. This quantitative study used data collected from US Treatment Episode Data Set for Admissions (TEDS - A) between 2015 and 2019, which helped to determine the relationship between cardholder and caregiver cultivation policies and the percent of CUD admissions. The results indicated that there is a negative relationship between states’ allowing of cardholders and caregivers to cultivate cannabis and CUD rates. Results from this study suggest that systemic factors play a strong role in whether or not marijuana laws are associated with CUD rates. Therefore, it is critical to now view the links between cannabis laws and usage disorders in isolate, and, to instead, consider the broader multidimensional nature of these relationships. Findings may be used by legislators to promote positive social change
