An amplitude analysis of the 𝐾𝑆𝐾𝑆 system produced in radiative 𝐽/𝜓 decays is performed using the (1310.6±7.0)×106 𝐽/𝜓 decays collected by the BESIII detector. Two approaches are presented. A mass-dependent analysis is performed by parametrizing the 𝐾𝑆𝐾𝑆 invariant mass spectrum as a sum of Breit-Wigner line shapes. Additionally, a mass-independent analysis is performed to extract a piecewise function that describes the dynamics of the 𝐾𝑆𝐾𝑆 system while making minimal assumptions about the properties and number of poles in the amplitude. The dominant amplitudes in the mass-dependent analysis include the 𝑓0(1710), 𝑓0(2200), and 𝑓′2(1525). The mass-independent results, which are made available as input for further studies, are consistent with those of the mass-dependent analysis and are useful for a systematic study of hadronic interactions. The branching fraction of radiative 𝐽/𝜓 decays to 𝐾𝑆𝐾𝑆 is measured to be (8.1±0.4)×10−4, where the uncertainty is systematic and the statistical uncertainty is negligible.
he process e+e−→pK0Sn¯K−+c.c. and its intermediate processes are studied for the first time, using data samples collected with the BESIII detector at BEPCII at center-of-mass energies of 3.773, 4.008, 4.226, 4.258, 4.358, 4.416, and 4.600 GeV, with a total integrated luminosity of 7.4 fb−1. The Born cross section of e+e−→pK0Sn¯K−+c.c. is measured at each center-of-mass energy, but no significant resonant structure in the measured cross-section line shape between 3.773 and 4.600 GeV is observed. No evident structure is detected in the pK−, nK0S, pK0S, nK+, pn¯, or K0SK− invariant mass distributions except for Λ(1520). The Born cross sections of e+e−→Λ(1520)n¯K0S+c.c. and e+e−→Λ(1520)p¯K++c.c. are measured, and the 90\% confidence level upper limits on the Born cross sections of e+e−→Λ(1520)Λ¯(1520) are determined at the seven center-of-mass energies.
Background: A diagnosis of post-traumatic stress disorder (PTSD) requires the identification of one or more traumatic events, designated the index trauma, which serves as the basis for assessment of severity of PTSD. In patients who have experienced more than one traumatic event, severity may depend on the exact definition of the index trauma. Defining the index trauma as the worst single incident may result in PTSD severity scores that differ from what would be seen if the index trauma included multiple events.
Objective: This study aimed to investigate the impact of the definition of the index trauma on PTSD baseline severity scores and treatment outcome.
Method: A planned secondary analysis was performed on data from a subset (N = 58) of patients enrolled in a trial evaluating the efficacy of a 12 week residential dialectical behavioural therapy programme for PTSD related to childhood abuse (DBT-PTSD). Assessments of the severity of PTSD were conducted at admission, at the end of the 12 week treatment period, and at 6 and 12 weeks post-treatment, using the Clinician-Administered PTSD Scale. The index trauma was defined with respect to both the worst single incident and up to three qualitatively distinct traumatic events.
Results: When the index trauma included multiple traumas, PTSD severity scores were significantly higher and improvements from pre- to post-treatment were significantly lower than when the index trauma was defined as the worst single incident.
Conclusions: In patients with PTSD who have experienced multiple traumas, defining the index trauma as the worst single incident may miss some aspects of clinically relevant symptomatology, thereby leading to a possibly biased interpretation of treatment effects. In DBT-PTSD, treatment effects were lower when the index trauma included multiple traumatic events. More research is needed to determine the impact of the various index trauma definitions on the evaluation of other trauma-focused treatments.
Begriffsgeschichte
(2018)
Die jüngeren Aufbrüche und Umbrüche haben den Begriff 'Begriffsgeschichte' nicht unberührt gelassen: "Als undogmatische Sammelbezeichnung für die Erforschung semantischer Veränderungsprozesse hat sich mittlerweile der Terminus historische Semantik interdisziplinär etabliert." Die Ausnüchterung des Begriffs im Terminus, der Begriffsgeschichte in der historischen Semantik, hilft bei der Abwehr prekärer und vielleicht auch gar nicht mehr zeitgemäßer Fragen, zumal der notorischen nach dem 'Begriff des Begriffs' der Begriffsgeschichte. Paradoxerweise drängen sie aber wieder, wenn sich die Begriffsgeschichte selbst historisch zu werden beginnt. Und da neben Interdisziplinarität und Internationalisierung auch Historisierung unabdingbar zum Ausweis wissenschaftlicher Geltung und Aktualität gehört, kommt Begriffsgeschichte um ihre Selbsthistorisierung gerade jetzt, zu Zeiten ihres späten Ruhmes, nicht herum.
Was bei Schrott aus seiner künstlerischen Bearbeitung der Wissens-'Tradition' geworden ist, ist nicht einfach zu sagen. Jedenfalls keine Naturreligion und keine Experimentaltheologie, sondern eine Dichtung, sehr groß dimensioniert, gewiss, aber doch stets nur "Stücke eines Epos: nicht in hehrem Anspruch, sondern als Poesie, die Welt enthält". Von Freuds Epostheorie her gesehen ist der befremdliche Titel "Erste Erde. Epos" gewissenhafte Leseanleitung: Achtung, Kunst! - Nicht beantwortet ist damit die Frage, warum Schrott die 'Tradition' von Wissenschaft und Wissenschaftsgeschichte literarisch bearbeitet hat.
Am 31. Januar fand am ZfL die Verleihung des Carlo-Barck-Preises an Kevin Liggieri statt. Liggieri erhielt den Preis für seine Dissertation "Zur Kultur- und Begriffsgeschichte der 'Anthropotechnik'. Eine Untersuchung programmatischer Diskurse zwischen 'Menschenzucht' und 'Menschenbehandlung'". Wir dokumentieren hier die beiden Reden von Eva Geulen und Ernst Müller anlässlich der Preisverleihung.
Der Artikel wirft einige Schlaglichter auf die Geschichtsbilder und -vorstellungen, die im modernen muslimischen religiösen Denken seit dem späten 19. Jahrhundert zum Tragen gekommen sind. Insbesondere im Blick steht dabei die Frage nach dem Umgang mit eigener Geschichtlichkeit und mit den Konsequenzen, die sich daraus für die Ausgestaltung von Islamität ergeben. Die unterschiedlichen Gewichtungen und Verknüpfungen von Vergangenheit und Gegenwart und die Frage, ob die Bedeutung des historischen Wandels für die eigenen Erkenntnisprozesse mitreflektiert wird, entscheidet, so die These, über den Umgang des religiösen Denkens mit neuen Wissensbeständen, Epistemen und methodischen Verfahren ebenso wie darüber, ob diese als legitim angesehen werden, um als authentisch islamisch akzeptiert zu werden.
TO MAKE PROFITABLE INVESTMENT DECISIONS, INVESTORS NEED TO ASSESS THE FINANCIAL FUTURE OF FIRMS. DUE TO INVESTORS’ LACK OF INTERNAL INFORMATION ABOUT THE FIRMS’ FUTURE PROSPECTS, THEY OFTEN HAVE TO RELY ON MANAGERS’ VERBAL STATEMENTS FOR THIS TASK. HOWEVER, AS MANAGERS MIGHT HAVE AN INCENTIVE TO PRESENT POSITIVELY BIASED INFORMATION, THE VALUE OF THEIR STATEMENTS FOR INVESTORS IS NOT CLEAR.
IN THIS REPORT, WE SHOW HOW TEXTUAL ANALYSIS TOOLS CAN BE USED TO ASSESS THE VALUE OF MANAGERS’ VERBAL STATEMENTS DURING EARNINGS CONFERENCE CALLS FOR INVESTORS. WE FIND THAT IN PARTICULAR MANAGERS’ NEGATIVE STATEMENTS SIGNI FICANTLY PREDICT LOWER FUTURE EARNINGS.
The cortical networks that underlie behavior exhibit an orderly functional organization at local and global scales, which is readily evident in the visual cortex of carnivores and primates1-6. Here, neighboring columns of neurons represent the full range of stimulus orientations and contribute to distributed networks spanning several millimeters2,7-11. However, the principles governing functional interactions that bridge this fine-scale functional architecture and distant network elements are unclear, and the emergence of these network interactions during development remains unexplored. Here, by using in vivo wide-field and 2-photon calcium imaging of spontaneous activity patterns in mature ferret visual cortex, we find widespread and specific modular correlation patterns that accurately predict the local structure of visually-evoked orientation columns from the spontaneous activity of neurons that lie several millimeters away. The large-scale networks revealed by correlated spontaneous activity show abrupt ‘fractures’ in continuity that are in tight register with evoked orientation pinwheels. Chronic in vivo imaging demonstrates that these large-scale modular correlation patterns and fractures are already present at early stages of cortical development and predictive of the mature network structure. Silencing feed-forward drive through either retinal or thalamic blockade does not affect network structure suggesting a cortical origin for this large-scale correlated activity, despite the immaturity of long-range horizontal network connections in the early cortex. Using a circuit model containing only local connections, we demonstrate that such a circuit is sufficient to generate large-scale correlated activity, while also producing correlated networks showing strong fractures, a reduced dimensionality, and an elongated local correlation structure, all in close agreement with our empirical data. These results demonstrate the precise local and global organization of cortical networks revealed through correlated spontaneous activity and suggest that local connections in early cortical circuits may generate structured long-range network correlations that underlie the subsequent formation of visually-evoked distributed functional networks.
This study will consider the various aspects of the portrayal of Sultan ʿAbd al-Ḥamīd II that were emphasized in the Arab-Islamist revisionist writings about Islamic history. The focus will be especially on the writings of Anwar al-Ǧundī (1917–2002), an Egyptian Islamist writer as it was he who first adopted the process of an “Islamic revision of Islamic history”. His main academic output consisted in responding to the “Orientalist attack on Islam”, and he wrote a number of books towards this aim as as-Sulṭān ʿAbd al-Ḥamīd wa l-ḫilāfa al-islāmiyya, al-Islām fī maʿrakat at-taġrīb and al-Istiʿmār wa l-Islām.
This will be followed by an analysis of the ideological exploitation of the historical personality, and the consequences of the contemporary historical Islamist vision for the development of religious thought.
Entstanden in einem Milieu aus exklusivistischen islamischen Bewegungen, baut die Gewalttheologie der dschihadistischen Organisationen wie der al-Qa‘ida oder des IS auf eine Geschichtstheologie, welche Verfalls- und Dekadenzdiagnosen über die Situation der islamischen Welt und der Muslime mit eschatologischen Elementen verknüpft. In der Konsequenz müsse diese Dekadenz zum Zerfall der Welt und zum Anbruch der Endzeit führen, als deren kämpfende Avantgarde und notwendige Vorbedingung sich die dschihadistischen Akteure stilisieren. Videos mit identifizierbaren erzählerischen Elementen gehören dabei zu zentralen Mitteln der dschihadistischen Kommunikation. Anhand eines Fallbeispiels untersucht der Artikel die geschichts- und gewalttheologisch geprägten Strukturen der IS-Videopropaganda. Zugleich wird auf im muslimischen Spektrum generierte Alternativen zu dieser exklusivistischen Geschichtstheologie verwiesen, die nicht von einem sich in der Geschichte enthüllenden ‘Heilsplan’ Gottes ausgehen, sondern auf der Prämisse der Unabgeschlossenheit und der offenen Bewegung menschlichen Denkens beruhen und damit eine Epistemologie anbieten, die nicht Spielarten des Identitären befördert.
Im Folgenden soll ein kurzer Überblick gegeben werden über die schiitische Sicht der frühislamischen Geschichte sowie über einige Phänomene, die sich daraus ergeben haben. Sie sind Hindernisse einer islamischen Einheit und müssten, sollte ein ernsthafter Versuch einer solchen verfolgt werden, mit deutlich mehr Mut angegangen werden. Dabei geht es hier weniger darum, alle Unterschiede zwischen Schia und Sunna aufzuzeigen, als sich auf die wirklich problematischen Felder zu konzentrieren, die nicht Folgen späterer, oft zufälliger Entwicklungen sind, sondern Weichenstellungen, die in der Frühgeschichte zu verorten sind. Bisher werden diese neuralgischen Punkte bei den Versuchen einer islamischen Ökumene, um diesen sehr christlich belegten Begriff an dieser Stelle doch einmal zu verwenden, meist umgangen, weil man um ihre Brisanz und Sprengkraft weiß. Doch müsste die Auseinandersetzung mit den unterschiedlichen Geschichtsbildern erfolgen, da sie ein wichtiges innerislamisches Differenzkriterium bilden; zumindest sollte man sich klar darüber sein, dass es unterschiedliche Geschichtsbilder gibt und sie ein Differenzkriterium bilden.
Background: Dialectical behaviour therapy for posttraumatic stress disorder (DBT-PTSD), which is tailored to treat adults with PTSD and co-occurring emotion regulation difficulties, has already demonstrated its efficacy, acceptance and safety in an inpatient treatment setting. It combines elements of DBT with trauma-focused cognitive behavioural interventions.
Objective: To investigate the feasibility, acceptance and safety of DBT-PTSD in an outpatient treatment setting by therapists who were novice to the treatment, we treated 21 female patients suffering from PTSD following childhood sexual abuse (CSA) plus difficulties in emotion regulation in an uncontrolled clinical trial.
Method: The Clinician Administered PTSD Symptom Scale (CAPS), the Davidson Trauma Scale (DTS), the Borderline Section of the International Personality Disorder Examination (IPDE) and the Borderline Symptom List (BSL-23) were used as primary outcomes. For secondary outcomes, depression and dissociation were assessed. Assessments were administered at pretreatment, post-treatment and six-week follow-up.
Results: Improvement was significant for PTSD as well as for borderline personality symptomatology, with large pretreatment to follow-up effect sizes for completers based on the CAPS (Cohens d = 1.30), DTS (d = 1.50), IPDE (d = 1.60) and BSL-23 (d = 1.20).
Conclusion: The outcome suggests that outpatient DBT-PTSD can safely be used to reduce PTSD symptoms and comorbid psychopathology in adults who have experienced CSA.
Background: Alternative splicing is a key regulatory mechanism in eukaryotic cells and increases the effective number of functionally distinct gene products. Using bulk RNA sequencing, splicing variation has been studied across human tissues and in genetically diverse populations. This has identified disease-relevant splicing events, as well as associations between splicing and genomic features, including sequence composition and conservation. However, variability in splicing between single cells from the same tissue or cell type and its determinants remains poorly understood.
Results: We applied parallel DNA methylation and transcriptome sequencing to differentiating human induced pluripotent stem cells to characterize splicing variation (exon skipping) and its determinants. Our results show that variation in single-cell splicing can be accurately predicted based on local sequence composition and genomic features. We observe moderate but consistent contributions from local DNA methylation profiles to splicing variation across cells. A combined model that is built based on genomic features as well as DNA methylation information accurately predicts different splicing modes of individual cassette exons. These categories include the conventional inclusion and exclusion patterns, but also more subtle modes of cell-to-cell variation in splicing. Finally, we identified and characterized associations between DNA methylation and splicing changes during cell differentiation.
Conclusions: Our study yields new insights into alternative splicing at the single-cell level and reveals a previously underappreciated link between DNA methylation variation and splicing.

Our results shows that splicing rates in single cells can be accurately predicted based on sequence composition and other genomic features. We also identified a moderate but significant contribution from DNA methylation to splicing variation across cells. By combining sequence information and DNA methylation, we derived an accurate model (AUC=0.85) for predicting different splicing modes of individual cassette exons. These explain conventional inclusion and exclusion patterns, but also more subtle modes of cell-to-cell variation in splicing. Finally, we identified and characterized associations between DNA methylation and splicing changes during cell differentiation.
Conclusions: Our study yields new insights into alternative splicing at the single-cell level and reveals a previously underappreciated component of DNA methylation variation on splicing.
Das neue Jahresthema des ZfL, FORMEN DES GANZEN, knüpft an das vorangegangene Jahresthema der DIVERSITÄT in den Bereichen der Natur, des Sozialen und der Kultur mit einer gewissen Zwangsläufigkeit an. Denn wer sich mit der Vielfalt beschäftigt, kann der Frage nach der Einheit der Vielfalt und damit nach dem Ganzen nicht ausweichen. So ist etwa das Schlagwort von der Biodiversität ein absolut inkludierender Begriff und damit Chiffre eines Ganzen. Allerdings wurden Ganzheitsvorstellungen im 20. Jahrhundert von Regimen in Anspruch genommen, die nicht zufällig 'totalitär' heißen. Auch deshalb stehen die heutigen Geisteswissenschaften dem Ganzen kritisch gegenüber. Jener Geist, der sie einmal als Wissenschaften binden und von den Naturwissenschaften unterscheiden sollte, gehört ja selbst zur Sippschaft unifizierender Begriffe, die ein Ganzes meinen oder behaupten.

Eugen Helmlé, 1927–2000
(2018)
Eugen Helmlé (1927–2000) war einer der verwegensten und besessensten Übersetzer seiner Zunft, der an die 150 Bücher übersetzt hat und in ganz besonderer Weise Georges Perec verbunden war, dem herausragenden französischen Autor des 1960 gegründeten Oulipo-Kreises, der gemeinsam mit seinem Übersetzer Helmlé neue formale Wege der Literaturproduktion beschritt.
With a notional amount outstanding of more than USD 500 trillion, the market for OTC derivatives is of vital importance for global financial stability. A growing proportion of these contracts are cleared via central counterparties (CCPs), which means that CCPs are gaining in importance as critical financial market infrastructures. At the same time, there is growing concern that a new „too big to fail" problem could arise, as the CCP industry is highly concentrated due to economies of scale. From a European perspective, it should be noted that the clearing of euro-denominated OTC derivatives mainly takes place in London, hence outside the EU in the foreseeable future. For some time there has been a controversial discussion as to whether this can remain the case post Brexit. CCPs, which clear a significant proportion of euro OTC derivatives and are systemically relevant from an EU perspective, should be subject to direct supervision by EU authorities and should be established in the EU. This would represent an important building block for a future Capital Markets Union in Europe, as regulatory or supervisory arbitrage in favour of systemically important third-country CCPs could be prevented. In addition, if a systemically relevant CCP handling a considerable portion of the euro OTC derivatives business were to run into serious difficulties, this may impact ECB monetary policy. This applies both to demand for central bank money and to the transmission of monetary policy measures, which can be significantly impaired, particularly in the event that the repo market or payment systems are disrupted. It is therefore essential for the ECB to be closely involved in the supervision of CCPs. Against this background, the draft amendment of EMIR (European Market Infrastructure Regulation) presented on 13 June 2017 is a step in the right direction. In addition, there is an urgent need to introduce a recovery and resolution mechanism for CCPs in the EU to complement the existing single resolution mechanism (SRM) for banks in the eurozone. Only then can the diverse interdependencies between banks and CCPs be adequately taken into account in the recovery and resolution programmes required in a financial crisis.
