An introduction to prison and drugs in Europe
No full textBook synopsis: This publication provides an overview of current knowledge and the latest developments in the field of drug use and prison in Europe. The report explores in depth the epidemiology of drug use and drug-related problems among the prison population, the available social and health service responses to drug-related problems in prison, including the most recent evidence of effectiveness, and the drug supply and markets inside prison. It also discusses recent and future challenges in this area. The report will be of interest to policymakers and their advisors, specialists and practitioners, researchers and scientists and all those concerned with the issue of prison and drugs
Prediction of leading-edge transition and relaminarization phenomena on a subsonic multi-element high-lift system
No full textBoundary-layer transition and relaminarization may have a critical effect on the flow development about multi-element high-lift systems of subsonic transport jets with swept wings. The purpose of the research is to study these transition phenomena in the leading-edge region of the various elements of a high-lift system. The flow phenomena studied include transition to the attachment-line flow, relaminarization, and crossflow instability, and transition. The calculations are based on pressure distributions measured in flight on the NASA Transport Systems Research Vehicle (Boeing 737-100) at a wing station where the flow approximated infinite swept wing conditions. The results indicate that significant regions of laminar flow can exist on all flap elements in flight. In future flight experiments (planned for January-February, 1994) the extent of these regions, the transition mechanisms and the effect of laminar flow on the high-lift characteristics of the multi-element system will be further explored
A generalized solution to verify authorship and detect style change in multi-authored documents
No full textASONAM '23, November 6–9, 2023, Kusadasi, TurkiyeIdentifying changes in style can be used to detect multi-authored social media accounts, plagiarism, compromised accounts, and author contributions in long documents. We propose an approach to recognize changes in authorship using large language models. Our approach leverages sentence-level contextual embeddings and semantic relationships. First we expand the training set by adding adversarial examples to the minority class [5], [13], [17]. Then we fine-tune a sequence classification transformer model to detect style change. Our approach outperforms all baselines of PAN21 with macro F1-scores of 0.80, 0.74, and 0.70 for detecting style changepoint between paragraphs, closed-set author ID per paragraph, and style changepoint between sentences, respectively. Our approach also performs better than the leading competitors in PAN22. Also, we achieved a five percent improvement in macro F1-score (0.78) on the newly introduced DarkReddit+ dataset for authorship verification

Comparing the PPVT and ROWPVT (Ingvalson et al., 2023)
No full textPurpose: We sought to compare raw scores, standard scores, and age equivalences on two commonly used vocabulary tests, the Peabody Picture Vocabulary Test (PPVT) and the Receptive One-Word Picture Vocabulary Test (ROWPVT).
Method: Sixty-two children, 31 with hearing loss (HL) and 31 with normal hearing (NH), were given both the PPVT and ROWPVT as part of an ongoing longitudinal study of emergent literacy development in preschoolers with and without HL. All children were between 3 and 4 years old at administration, and the two tests were administered within 3 weeks of each other. Both tests were given again 6 months later. Standard scores and age equivalencies were calculated for both tests using published guidelines.
Results: There was no significant effect of test for any of our analyses. However, there was a main effect of time, with both standard scores and age equivalencies being significantly higher at the second test. Children with NH had significantly higher standard scores and age equivalencies than children with NH, but there was no interaction between hearing status and time, suggesting that the two groups were growing at the same rate.
Conclusions: Clinicians can be comfortable administering both the PPVT and ROWPVT to estimate children’s vocabulary levels, but there may be practice effects when administering the tests twice within a calendar year. These data also indicate that children with HL continue to lag behind their peers with NH on vocabulary development.

Each group comprised 20 participants, providing 94% power to detect statistically significant associations with CGRP concentration for either TMD or migraine. TMD and headache were classified according to the Diagnostic Criteria for TMD and the International Classification for Headache Disorders, 3rd edition, respectively. Plasma CGRP was quantified with a validated high-sensitivity electrochemiluminescent Meso Scale Discovery assay. Questionnaires and clinical examinations were used to evaluate characteristics of TMD, headache, psychological distress, and pressure pain sensitivity. Univariate regression models quantified associations of the CGRP concentration with TMD, migraine, and their interaction. Univariate associations of the CGRP concentration with clinical, psychological, and pressure pain characteristics were also assessed.Results: Among 80 participants enrolled, neither TMD nor migraine was associated with plasma CGRP concentration (P = 0.761 and P = 0.972, respectively). The CGRP concentration (mean ± SD) was similar in all 4 groups: HCs 2.0 ± 0.7 pg/mL, TMD 2.1 ± 0.8 pg/mL, migraine 2.1 ± 0.9 pg/mL, and TMD with migraine 2.2 ± 0.7 pg/mL. CGRP concentration was positively associated with age (P = 0.034) and marginally with body mass index (P = 0.080) but was unrelated to other participant characteristics.Conclusion: In this well-powered study, interictal plasma concentration of CGRP was a poor biomarker for TMD and migraine.Keywords: orofacial pain, musculoskeletal pain, neuropeptide, temporomandibular joint disorders, headach
High angle-of-attack aerodynamic characteristics of crescent and elliptic wings
No full textStatic longitudinal and lateral-directional forces and moments were measured for elliptic- and crescent-wing models at high angles-of-attack in the NASA Langley 14 by 22-Ft Subsonic Tunnel. The forces and moments were obtained for an angle-of-attack range including stall and post-stall conditions at a Reynolds number based on the average wing chord of about 1.8 million. Flow-visualization photographs using a mixture of oil and titanium-dioxide were also taken for several incidence angles. The force and moment data and the flow-visualization results indicated that the crescent wing model with its highly swept tips produced much better high angle-of-attack aerodynamic characteristics than the elliptic model. Leading-edge separation-induced vortex flow over the highly swept tips of the crescent wing is thought to produce this improved behavior at high angles-of-attack. The unique planform design could result in safer and more efficient low-speed airplanes
