Ausgangspunkt: Die Kritik am "Zwei-Welten-Modell": Die grundlegende linguistische Unterscheidung zwischen "Sprache" und "Sprechen" ist im Rahmen der neueren Debatten um Sprachmedialität wieder verstärkt thematisiert und kritisiert worden. Lässt sich dieses schulbildende, in der Linguistik geradezu eherne Begriffspaar überhaupt noch sinnvollerweise aufrechterhalten? Oder muss es mindestens umdefiniert, vielleicht sogar gänzlich verworfen werden? Hat sich insbesondere die auf Chomsky zurückgehende Unterscheidung von Sprachkompetenz und -performanz nicht von selbst ad absurdum geführt, nachdem der linguistische Kognitivismus chomskyscher Provenienz Sprache als lebendiges Phänomen, als Medium menschlicher Kommunikation, vollständig aus dem Blick verloren hat? Führt nicht schon die scheinbar harmlose linguistische Differenzierung zwischen einer Sprachregel und ihrer Anwendung zu einer irreführenden und unangemessenen Verdinglichung von Sprache? ...
Woher kommt das neuerwachte Interesse an Sprachrichtigkeit? Woher kommt die ausgeprägte sprachliche Unsicherheit, die auch bei vielen hochgebildeten Menschen den Wunsch entstehen lässt, von Sprachpflegern über ihr Ureigenstes, nämlich ihre Muttersprache, belehrt zu werden? Obwohl Antworten auf diese Fragen letztlich spekulativ bleiben, wage ich doch die These, dass eine Ursache hierfür die Rechtschreibreform ist, die von einem Großteil der Bevölkerung nach wie vor nicht angenommen wird, die insgesamt weder zur Vereinfachung noch zu einer höheren Einheitlichkeit geführt hat; die aber andererseits ein öffentliches Nachdenken und Diskutieren über Sprachrichtigkeit in Gang setzte. – Jedenfalls ist die Verunsicherung ein Faktum, das von Linguisten nicht ignoriert werden sollte.
Die Themen Sprachrichtigkeit und Sprachidentität haben in Deutschland seit einiger Zeit Hochkonjunktur. Der 'Sprachpfleger' Bastian Sick, in der massenmedialen Berichterstattung stereotyp als gleichermaßen "kompetent" wie "lustig" und "gar nicht oberlehrerhaft" angepriesen, verkauft seine Kolumnensammlungen millionenfach und füllt bei seinen Lesungen mühelos ganze Konzertsäle. Der Verein Deutsche Sprache, Speerspitze der Anglizismenkritik im deutschsprachigen Raum, hat nach eigenen Angaben mittlerweile fast 30.000 Mitglieder. Betrachtet man diese Protagonisten des öffentlichen Sprachdiskurses aus linguistischer Perspektive, so stellt man fest, dass sich die von ihnen propagierte Sprachauffassung in der Regel an einer alten Metapher orientiert – der biologistischen Metapher von Sprache als einem Organismus: Ein Organismus kann geboren werden und sterben; er kann krank werden und verfallen, er ist – um es mit einem Ausdruck von Jürgen Spitzmüller zu sagen – eine klar "abgrenzbare Einheit". Ein Sprachsystem erscheint somit als ein abgeschlossenes organisches Gebilde, welches es zu erhalten gilt und das durch schädliche Einflüsse von außen in seiner Identität gefährdet ist.
The Transition Radiation Detector (TRD) was designed and built to enhance the capabilities of the ALICE detector at the Large Hadron Collider (LHC). While aimed at providing electron identification and triggering, the TRD also contributes significantly to the track reconstruction and calibration in the central barrel of ALICE. In this paper the design, construction, operation, and performance of this detector are discussed. A pion rejection factor of up to 410 is achieved at a momentum of 1 GeV/c in p–Pb collisions and the resolution at high transverse momentum improves by about 40% when including the TRD information in track reconstruction. The triggering capability is demonstrated both for jet, light nuclei, and electron selection.

Background: Predicted increases in suicide were not generally observed in the early months of the COVID-19 pandemic. However, the picture may be changing and patterns might vary across demographic groups. We aimed to provide a timely, granular picture of the pandemic's impact on suicides globally.
Methods: We identified suicide data from official public-sector sources for countries/areas-within-countries, searching websites and academic literature and contacting data custodians and authors as necessary. We sent our first data request on 22nd June 2021 and stopped collecting data on 31st October 2021. We used interrupted time series (ITS) analyses to model the association between the pandemic's emergence and total suicides and suicides by sex-, age- and sex-by-age in each country/area-within-country. We compared the observed and expected numbers of suicides in the pandemic's first nine and first 10-15 months and used meta-regression to explore sources of variation.
Findings: We sourced data from 33 countries (24 high-income, six upper-middle-income, three lower-middle-income; 25 with whole-country data, 12 with data for area(s)-within-the-country, four with both). There was no evidence of greater-than-expected numbers of suicides in the majority of countries/areas-within-countries in any analysis; more commonly, there was evidence of lower-than-expected numbers. Certain sex, age and sex-by-age groups stood out as potentially concerning, but these were not consistent across countries/areas-within-countries. In the meta-regression, different patterns were not explained by countries’ COVID-19 mortality rate, stringency of public health response, economic support level, or presence of a national suicide prevention strategy. Nor were they explained by countries’ income level, although the meta-regression only included data from high-income and upper-middle-income countries, and there were suggestions from the ITS analyses that lower-middle-income countries fared less well.
Interpretation: Although there are some countries/areas-within-countries where overall suicide numbers and numbers for certain sex- and age-based groups are greater-than-expected, these countries/areas-within-countries are in the minority. Any upward movement in suicide numbers in any place or group is concerning, and we need to remain alert to and respond to changes as the pandemic and its mental health and economic consequences continue.
Sprache als kranker Organismus : linguistische Anmerkungen zum Spiegel-Titel "Rettet dem Deutsch!"

Background: About 2000 children and adolescents under the age of 18 are diagnosed with cancer each year in Germany. Because of current medical treatment methods, a high survival rate can be reached for many types of the disease. Nevertheless, patients face a number of long-term effects related to the treatment. As a result, physical and psychological consequences have increasingly become the focus of research in recent years. Social dimensions of health have received little attention in health services research in oncology so far. Yet, there are no robust results that allow an estimation of whether and to what extent the disease and treatment impair the participation of children and adolescents and which factors mediate this effect. Social participation is of great importance especially because interactions with peers and experiences in different areas of life are essential for the development of children and adolescents.
Methods: Data are collected in a longitudinal, prospective, observational multicenter study. For this purpose, all patients and their parents who are being treated for cancer in one of the participating clinics throughout Germany will be interviewed within the first month after diagnosis (t1), after completion of intensive treatment (t2) and half a year after the end of intensive treatment (t3) using standardized questionnaires. Analysis will be done by descriptive and multivariate methods.
Discussion: The results can be used to identify children and adolescents in high-risk situations at an early stage in order to be able to initiate interventions tailored to the needs. Such tailored interventions will finally reduce the risk of impairments in the participation of children and adolescents and increase quality of life.

Plastid DNA sequence data have been traditionally widely used in plant phylogenetics because of the high copy number of plastids, their uniparental inheritance, and the blend of coding and non-coding regions with divergent substitution rates that allow the reconstruction of phylogenetic relationships at different taxonomic ranks. In the present study, we evaluate the utility of the plastome for the reconstruction of phylogenetic relationships in the pantropical plant family Ochnaceae (Malpighiales). We used the off-target sequence read fraction of a targeted sequencing study (targeting nuclear loci only) to recover more than 100 kb of the plastid genome from the majority of the more than 200 species of Ochnaceae and all but two genera using de novo and reference-based assembly strategies. Most of the recalcitrant nodes in the family’s backbone were resolved by our plastome-based phylogenetic inference, corroborating the most recent classification system of Ochnaceae and findings from a phylogenomic study based on nuclear loci. Nonetheless, the phylogenetic relationships within the major clades of tribe Ochnineae, which comprise about two thirds of the family’s species diversity, received mostly low support. Generally, the phylogenetic resolution was lowest at the infrageneric level. Overall there was little phylogenetic conflict compared to a recent analysis of nuclear loci. Effects of taxon sampling were invoked as the most likely reason for some of the few well-supported discords. Our study demonstrates the utility of the off-target fraction of a target enrichment study for assembling near-complete plastid genomes for a large proportion of samples.
