description: While interest in art-based interventions is growing rapidly, little is known about the aesthetic, material, and interpersonal mechanisms by which art interventions, and musical interventions in particular, operate. We address this gap by drawing from an in-depth case study of a musical intervention in a professional ice-hockey team in Finland. At the time of the study, the organization faced a serious crisis, having lost 11 sequential games, leading its managers to search for “alternative” means for promoting social cohesion, and subsequently engaging in an arts-based musical intervention. Our findings examine how material objects and collective synchronization rhythms grounded the interpersonal interactions of team members and mediated members' attempts to transform personal subjective experiences into collective collaboration. We draw out the conceptual implications of our findings for understanding, on the one hand, the collective nature of aesthetic processes, and on the other hand, the materially mediated processes of communication. In terms of practical implication, we contribute to understanding the social dynamics and transformative organizational possibilities of artistic interventions that generate value for the organization and its members.

description: Rassismus als Macht- und Herrschaftsverhältnis durchdringt alle Ebenen des Zusammenlebens. Entsprechend tragen auch Bildungsinstitutionen wie eine Hochschule für Soziale Arbeit dazu bei, Rassismus zu aktualisieren. Mehr noch als die Soziale Arbeit allgemein ist die Hochschule ein weißer Raum – zumindest auf der Seite der Lehrenden. Doch inzwischen ist an einigen Stellen etwas in Bewegung geraten: Es mehren sich Wille und Wissen, rassismuskritisches Denken und Selbstreflexion zu fördern. Der folgende Artikel geht diesen Bewegungen nach, u. a. im Rahmen eines intensiven Gesprächs über ein abgeschlossenes Projekt zu Empowerment und Verlernen von Rassismus an der Berner Fachhochschule. Er gibt überraschende Einsichten frei zu den Spannungsfeldern und Erkenntnissen rassismuskritischer Arbeit im Kontext von Hochschule und Sozialer Arbeit.
description: Racism as a relationship of power and domination permeates all levels of coexistence. Accordingly, educational institutions such as a university of social work also contribute to the actualization of racism. Even more than social work in general, the university is a white space, at least on the teaching side; however, there is now movement in many areas: There is a growing will and knowledge to promote antiracist thinking and self-reflection. This article explores these movements, including an in-depth discussion about a completed project on empowerment and unlearning racism at Bern University of Applied Sciences. It provides surprising insights into the areas of tension and findings of antiracist work in higher education and in the context of social work.

description: The application of pre-stressed CFRP-Iamella to timber beams is difficult because the concentrated shear stresses at the beam ends often lead to delamination of the lamella or to timber failure due to tension perpendicular to the grain. An alternative method involving decreased pre-tension force towards the beam ends shows promising results, but requires large and heavy equipment and is therefore not suitable for on-site applications. In order to post-strengthen historic wooden beams with CFRF-Iamella, a different approach of prestressing was developed where the timber beam is cambered prior to the bonding of the CFRP-Iamella with an epoxy resin. In short-term bending tests the potential efficiency of the method was confirmed by increased bending stiffness (+14%) and bending strength (approx. + 30%). In order to assess the long-term behaviour of timber after pre-stressing and CFRP reinforcement, six loaded and three unloaded spruce battens were exposed to seven climate regimes of one week duration each. Although the exposure time of each cycle was too short to reach moisture equilibrium, the cycling of temperatures between 19° and 49°C and relative humidities between 36% and 70% induced average wood moisture changes of up to 3.3%. Creep deflection of the beams showed a progressive trend in the first three cycles, where the timber is supposed to undergo plastic deformation, the deflection gradient reduces in the second part of the exposure time. The comparison of the creep factor of the loaded and unloaded specimens and the unchanged MOE of the battens after loading in cycling climate provided evidence that the reinforcing system, especially the applied epoxy resin, is able to withstand cyclic changes in climate class 2 without relevant stress relaxation.

description: Etmopterus sheikoi (Dolganov, 1986)
Type locality: Kyushu Palau Ridge, western North Pacific.
The two Taiwanese E. sheikoi samples included in this analysis formed a single cluster that included a sample (GN7440) from Taiwan. As discussed in Straube et al. (2010), the species is inferred to be the sister group to the E. lucifer clade. Potential misidentification can be ruled out as the morphology is highly distinctive and specimens analysed herein are vouchered. The phylogenetic affinities of E. sheikoi are especially interesting. Straube et al. (2010) showed that flank markings in Etmopterus mirror the relationships inferred from molecular data for all species, except E. sheikoi. From a morphological perspective, the species would be expected to cluster within the E. pusillus clade rather than the E. lucifer clade as suggested by the molecular data (Figure 2). This is an unusual case in which morphology and genetics are inconsistent and need further data collection and analysis from both approaches. This species was previously allocated to the genus Miroscyllium, but molecular data suggest this species belongs to the genus Etmopterus.

description: Este artigo investiga a evolução do exercício do poder e do controle social desde a era pré-moderna até a contemporaneidade do capitalismo de vigilância, destacando a crescente sutileza e abrangência do poder mediado por tecnologias digitais. O estudo adota uma abordagem hipotético-dedutiva e utiliza uma metodologia bibliográfica para explorar como as transformações tecnológicas e socioeconômicas reconfiguraram as dinâmicas de poder e controle. Os resultados confirmam a hipótese de que o poder se tornou menos perceptível e mais integrado ao cotidiano, estendendo-se além dos limites tradicionais do espaço público e privado. Essa nova configuração de poder caracteriza-se por uma vigilância contínua que, apesar de oferecer conveniências, levanta questões críticas sobre privacidade e autonomia individual.

description: 1. Vanilla sprucei Rolfe (1896: 461) (Figures 3D–E, 5 A–F)
Type:— COLOMBIA. In shady woods near the Uaupes River, on the Upper Amazon, Spruce 2727 (holotype: K001382262!).
Distribution:— Colombia, Guyana, Venezuela (Figure 4).
Taxonomic Discussion:—The distinguishing features of this species are its slender leaves, which dry black and have prominent secondary veins. The inflorescences are usually paniculate, with whitish flowers that have linear petals and a cushion-like apex lip. This report is the first to identify the species in the Guiana Shield regions of Guyana, and Venezuela. Vegetatively, the plant shares some similarities with V. trigonocarpa, but it is easily distinguishable by the branching (vs. ramose) inflorescences. The flowers of V. trigonocarpa are twice as large as those of V. sprucei, with the sepals of the former measuring 10.5–11.5 × 1.6–2 cm (vs. 4.9–5.0 × 0.5 cm). Furthermore, V. trigonocarpa has an emarginate lip apex, while V. sprucei exhibits a sub-acute shape.
Szlachetko (2016) assigned one of the specimens cited below (Redden 2518) to V. guianensis, which can be easily distinguished from V. sprucei by its elliptic (vs. obovate) leaves and distinct floral morphology, including a hexagonal lip and the absence of a penicillate callus.

description: Along with the diagnostic process for sleep disor- ders, a diversity of clinical assessments are required to diagnose the concrete type of sleep disorder. For an accurate diagnosis, a variety of medical examinations are conducted, whose results are documented in clinical records. The textual records form the basis for disease categorization and cohort creation using the International Classification for Sleep Disorder (ICSD-III). However, textual records generated through patient-physician interaction may contain different types of biases caused by the heterogeneous nature of medical specialties and the used vocabu- lary in the documentation. In this work, we will analyze different types of semantic biases and driftings in the context of sleep disorder diagnosis using the Bern Sleep Database. The database contains documents describing the clinical history, referring reasons and results from different assessments (polysomnography (PSG), multiple sleep latency test (MSLT), maintenance of wake- fulness test (MWT), actigraphy (Wrist, PLMS)) from more than 6000 patients. An enhanced text-based ICSD-III classification (Multichannel CNN and Hierachical attentive networks) using a standardized concept representation will be proposed. We will analyze the influence of semantic bias on the accuracy of this automatic classification.
Social exclusion of people with severe mental illness in Switzerland: results from the Swiss Health Survey

description: Aims. People with severe mental illness (SMI) have a high risk of living socially excluded from the mainstream society. Policy initiatives and health systems aim to improve the social situation of people who suffer from mental health disabilities. The aim of this study was to explore the extent of social exclusion (employment and income, social network and social activities, health problems) of people with SMI in Switzerland. Methods. Data from the Swiss Health Survey 2012 were used to compare the social exclusion magnitude of people with SMI with those suffering from severe physical illness, common mental illness and the general population. Results. With the exception of Instrumental Activities of Daily Living, we found a gradient of social exclusion that showed people with SMI to be more excluded than the comparison groups. Loneliness and poverty were widespread among people with SMI. Logistic regression analyses on each individual exclusion indicator revealed that people with SMI and people with severe physical illness were similarly excluded on many indicators, whereas people with common mental illness and the general population were much more socially included. Conclusions. In contrast to political and health system goals, many people with SMI suffer from social exclusion. Social policy and clinical support should increase the efforts to counter exclusionary trends, especially in terms of loneliness and poverty

description: Introduction It is important to assess and quantify gait in order to determine the severity of impairments during gait and to evaluate therapeutic interventions. However, laboratory gait assessment is expensive and time consuming and there is a lack of an easily applicable tool for the quantification of gait in clinical practice. The aim of this study was to validate a smartphone-based measurement tool for the quantification of level walking. Methods Vertical center of mass displacement and step duration of 22 healthy young adults were assessed by a smartphone application and a motion capture system. Intra-session reliability was evaluated by repeated-measures ANOVA, intraclass correlation coefficient (ICC), and standard error of measurement. In order to evaluate the concurrent validity of the smartphone application, smartphone- and motion capture-derived values were compared by Pearson correlation coefficient and Bland-Altman limits of agreement. Results Six out of eight variables derived by the smartphone application showed an excellent reliability (ICC ≥ 0.75) and all variables correlated significantly with measurements of the motion capture system with moderate to strong correlations ranging from 0.61 to 0.92. Conclusion The results showed a great potential of the smartphone application to be a user-friendly and valid tool for the assessment of gait in clinical practice. Further research needs to investigate whether the smartphone application is able to detect differences in gait patterns following therapeutic or orthopedic interventions and whether it is valid for the quantification of gait in people with movement disorders.

description: 2. Vanilla dressleri Soto Arenas (2010: 303) (Figure 5 G, H)
Type:— PANAMA. Colón: end of Pipeline Road on Río Agua Salud, 20–50 m, 15 April 1982, S. Knapp & J. Mallet 4621 (holotype: MO3032052!).
Distribution:— Panama, Costa Rica, Colombia, Venezuela, French Guiana (Figure 4).
Taxonomic Discussion:—This species is part of a group that includes Vanilla cribbiana Soto Arenas (2010: 300), Vanilla hostmanni Rolfe (1896: 462), and V. corinnae. These species feature long inflorescences with a densely papillose rachis and sepals, and yellowish to orange flowers. What sets V. dressleri species apart is the sub-rhombic lip, which is unlobed and has flat, minutely papillose veins. While initially thought to be restricted to Costa Rica, Panama and Colombia, the distribution is here expanded to include Venezuela and French Guiana.
The French Guiana specimen cited here (Cremers et al. 13016) was identified as Vanilla porteresiana Veyret & Szlach. (1995: 219) by Szlachetko (2016). However, we concur with Soto Arenas & Dressler’s (2010) assessment that V. porteresiana is based on an immature flower of V. hostmanni. The wide dorsal keel on the petals depicted for V. porteresiana (Figure 1 in Szlachetko & Veyret 1995) is characteristic of the immature petals of V. hostmanni, whereas in mature flowers the keel becomes slimmer. We have compared immature flowers (3 cm long) of V. hostmanni from Peruvian material with the drawings provided for V. porteresiana and found no significant differences. Additionally, we were unable to distinguish V. barrereana Veyret & Szlach. (1995: 2020) which appears to be based on mature flowers as evidenced by its narrow dorsal petal keel and larger size, from any Peruvian, Ecuadorian, or Brazilian specimens of V. hostmannii that we examined. Even though V. hostmannii and V. dressleri share features, such as the papillose external sepals and thickened veins in the lip, they can be easily differentiated by their lip morphology. V. hostmannii has a clearly trilobed lip, while V. dressleri has a sub-rhombic lip shape.

description: Για τους σκοπούς της παρούσας διπλωματικής εργασίας , πραγματοποιήθηκε πειραματική παραγωγή βερμούτ extra-dry από οίνο βάσης ποικιλίας Σαββατιανό. Οι συνθήκες της παραγωγικής διαδικασίας ήταν στα πλαίσια εκμάθησης των βέλτιστων συνθηκών για κάθε βήμα της διαδικασίας αυτής, με αποτέλεσμα την παραγωγή ενός τελικού προϊόντος που να πληροί τα νομοθετικά αλλά και οργανοληπτικά χαρακτηριστικά ενός extra-dry βερμούτ. Για να επιτευχθεί αυτό, ετοιμάστηκαν δείγματα στα οποία ναι μεν ακολουθήθηκαν τα ίδια στάδια και τεχνικές αλλά σε διαφορετικούς χρόνους έτσι ώστε να επιλεχθεί το ιδανικό δείγμα για την πορεία της εργασίας. Αυτό είχε σαν αποτέλεσμα την συνολική παραγωγή είκοσι λίτρων πειραματικού βερμούτ , χωρισμένο σε 4 διαφορετικές κατηγορίες ως προς τους χρόνους εκχύλισης . Οι δοκιμαστές των τελικών προϊόντων και οι φοιτητές που πραγματοποιήσανε την εργασία , πήραν μέρος σε οργανοληπτικό έλεγχο των δειγμάτων αυτών έτσι ώστε να καταλήξουμε σε συμπεράσματα για το ιδανικότερο δείγμα βερμούτ που παρασκευάστηκε . Μέσω της διαδικασίας αυτής, ανακαλύφθηκαν οι απαιτήσεις, δυσκολίες και τεχνικές γνώσεις που απαιτούνται για την παραγωγή ενός πειραματικού αλκοολούχου ποτού αλλά και την ομορφιά και ικανοποίηση που περιλαμβάνει η διαδικασία αυτή. Φυσικά και ευελπιστούμε στο μέλλον να μάθουμε και να ασχοληθούμε παραπάνω με την παραγωγή και χρήση του βερμούτ στις μέρες μας .

description: Τα φυσικά ροφήματα, που χαρακτηρίζονται από χαμηλή περιεκτικότητα σε ζάχαρη και πλούσιο διατροφικό προφίλ, έχουν συγκεντρώσει σημαντική προσοχή μέσω της αυξημένης ζήτησης των καταναλωτών για προϊόντα με άξονα την υγεία. Η παρούσα εργασία διερευνά τον πολύπλευρο κλάδο των φυσικών ποτών χαμηλής περιεκτικότητας σε ενέργεια, αποσαφηνίζοντας τα ποικίλα οφέλη και τις μελλοντικές προοπτικές τους. Διερευνώντας τη διασταύρωση της επιστήμης και των προτιμήσεων των καταναλωτών, η εργασία εμβαθύνει στις στρατηγικές διαχείρισης βάρους, αποκαλύπτοντας το ρόλο αυτών των ποτών στη συγκράτηση των θερμίδων χωρίς να θυσιάζονται τα οργανοληπτικά χαρακτηριστικά ή η διατροφική αξία. Οι γνώσεις σχετικά με τη μεταβολική υγεία υπογραμμίζουν τα πιθανά οφέλη στην ευαισθησία στην ινσουλίνη και τη ρύθμιση της γλυκόζης, τοποθετώντας τα φυσικά ποτά ως κεντρικά στοιχεία στην επιδίωξη της ολικής ευημερίας. Οι εκτιμήσεις για την καρδιαγγειακή υγεία ταυτίζονται με τις σύγχρονες διατροφικές συστάσεις, δίνοντας έμφαση στη μειωμένη πρόσληψη ζάχαρης και προωθώντας την καθιέρωση αυτών των ροφημάτων ως εύλογων εναλλακτικών επιλογών. Η διερεύνηση των αντιοξειδωτικών ιδιοτήτων διευκρινίζει τη λειτουργική σημασία των φαινολικών ενώσεων, συμβάλλοντας όχι μόνο στην ποιότητα των ποτών αλλά και σε πιθανά πλεονεκτήματα για την υγεία. Οι εκτιμήσεις για την αειφορία και τις περιβαλλοντικές επιπτώσεις προσθέτουν μια κρίσιμη διάσταση, αναδεικνύοντας την ανάγκη για πρακτικές με οικολογική συνείδηση στη βιομηχανία ποτών. Οι ρυθμιστικές γνώσεις περιηγούνται στο πολύπλοκο τοπίο των απαιτήσεων επισήμανσης και των ισχυρισμών υγείας, εξασφαλίζοντας την εμπιστοσύνη των καταναλωτών και τη λήψη τεκμηριωμένων αποφάσεων. Κατά την εξέταση των οργανοληπτικών χαρακτηριστικών των φυσικών ποτών χαμηλής ενέργειας, αντιθέτως, προκύπτει η ανάγκη για λεπτομερή κατανόηση του τρόπου με τον οποίο οι φαινολικές ενώσεις επηρεάζουν τη γεύση, το άρωμα και την αίσθηση στο στόμα, παρέχοντας έναν οδηγό για τα οργανοληπτικά χαρακτηριστικά που απαιτούνται για την ανάπτυξη τέτοιων προϊόντων. Η σύνθεση αυτών των ενοτήτων αποδίδει μια ολιστική προοπτική για τα φυσικά ροφήματα, προσφέροντας πολύτιμες συνεισφορές στην καινοτομία του κλάδου, στην ευαισθητοποίηση των καταναλωτών και στο δυναμικό τους μέλλον.

Type:— FRENCH GUIANA. Cayenne: Kourou, forêt de transition entre Savane de Matiti et fleuve Kourou, March 2017, A. Sambin, G. Chiron, J. Guiard & C. Sambin 1038 (holotype: CAY225561!; isotypes: HJBG 0049!, LY0018955!, LY0006937!).
Distribution:— French Guiana, Venezuela (Figure 4).
Taxonomic Discussion:—This species is not vegetatively distinct from other V. hostmannii -like species such as V. cribbiana, V. hostmannii, and V. dressleri. However, it can be easily differentiated during flowering by its fan-shaped lip which is not as strongly trilobed as the other three species. Additionally, the rachis and sepals of this species appear to be less densely papillose than those of V. hostmannii and more similar to V. cribbiana or V. dressleri.
During an herbarium revision, numerous specimens with papillose sepals resembling V. corinnae were discovered, but unfortunately, their flowers were not well-preserved. Therefore, it was not possible to confirm whether the species is present in other countries within the Guiana Shield. However, considering that V. corinnae has been identified in Venezuela and the type material originates from French Guiana, it is probable that the species also occurs in Suriname, Guyana, and Brazil. Collecting additional specimens from these regions would greatly assist in confirming these assumptions. The following record represents the first time V. corinnae is observed outside French Guiana, extending it known geographic range.
Specimens examined:— VENEZUELA. Amazonas: Along river just below mouth of Rio Cunucunuma, 24 May 1959, J. J. Wurdack & L. S. Adderley 43170 [flower] (US 00319617, NY01075145, NY01075147, P00367035).

Subjects: Cyclists Sinus node disease Arrhythmias Endurance training Atrial fibrillation Atrial flutter

description: Aims: Significant brady- and tachyarrhythmias may occur in active endurance athletes. It is controversial whether these arrhythmias do persist after cessation of competitive endurance training. Methods and results Among all 134 former Swiss professional cyclists [hereafter, former athletes (FAs)] participating at least once in the professional bicycle race Tour de Suisse in 1955–1975, 62 (46%) were recruited for the study. The control group consisted of 62 male golfers matched for age, weight, hypertension, and cardiac medication. All participants were screened with history, clinical and echocardiographic examination, ECG, and 24 h ECG. The time for the last bicycle race of FA s was 38 ± 6 years. The mean age at examination was 66 ± 6 years in controls and 66 ± 7 years in FA s ( P = 0.47). The percentage of study participants with >4 h current cardiovascular training per week was identical. QRS duration (102 ± 20 vs. 95 ± 13 ms, P = 0.03) and corrected QTc interval (416 ± 27 vs. 404 ± 18, P = 0.004) were longer in FA s . There was no significant difference in the number of isolated atrial or ventricular premature complexes, or supraventricular tachycardias in the 24 h ECG; however, ventricular tachycardias tended to occur more often in FA s than in controls (15 vs. 3%, P = 0.05). The average heart rate was lower in FA s (66 ± 9 vs. 70 ± 8 b.p.m.) ( P = 0.004). Paroxysmal or persistent atrial fibrillation or flutter was reported more often in FA s ( P = 0.028). Sinus node disease (SND), defined as bradycardia of <40 b.p.m. (10 vs. 2%), atrial flutter (6 vs. 0%), pacemaker for bradyarrhythmias (3 vs. 0%), and/or maximal RR interval of >2.5 s (6 vs. 0%), was more common in FA (16%) than in controls (2%, P = 0.006). Observed survival of all FAs was not different from the expected. Conclusions: Among FAs, SND occurred significantly more often compared with age-matched controls, and there is trend towards more frequent ventricular tachycardias. Further studies have to evaluate prevention of arrhythmias with extreme endurance training, the necessity of regular follow-up of heart rhythm, and management of arrhythmias in former competitive endurance athletes.
Effect of Addition of Micro-Sized Silicon Nitride on the Thermal Properties of the Epoxy Composites
Creators: name: Subham Dhar
Publisher: name: Zenodo
Year: 2024

description: In the present investigation, the effect of the addition of silicon nitride particulates in the epoxy resin is investigated and presented. The main concentration of the work is on the thermal properties of the developed material. The properties under investigation are thermal conductivity, glass transition temperature and coefficient of thermal expansion. All the properties are determined as a function of filler loading. The effect of modification of the surface of the silicon nitride using a silane coupling agent on the mentioned properties of the composites is also investigated. Four sets of composite specimens with filler content ranging up to 40 wt. % has been fabricated using a simple hand lay-up technique. From the experimental results, it is found that the inclusion of silicon nitride in the epoxy resin increases the thermal conductivity and glass transition temperature of the composite body as a function of filler loading. While studying the coefficient of thermal expansion, it is observed that the inclusion of filler gainfully decreases the coefficient of thermal expansion of the composite. It is also observed that the composite prepared with silane-modified silicon nitride shows better thermal properties as compared to its counterpart for a given filler loading due to the improvement in adhesion between the two phases.
