Kognitive Aktivierung im Sportunterricht: ein Scoping Review zur Umsetzung methodisch-didaktischer Merkmale und zugrundeliegender konzeptioneller Grundannahmen
Authors: Engelhardt Sophie , Hapke Julia , Töpfer Clemens 
Published: September 2023

ZusammenfassungIn der empirischen Bildungsforschung gilt kognitive Aktivierung als bedeutsame Dimension von Unterrichtsqualität, die fachspezifisch konkretisiert werden muss. Die Idee, dass sich Schüler*innen vertieft mental mit dem Lerngegenstand auseinandersetzen, findet sich für das Fach Sport auch in anderen Ansätzen wieder (z. B. Aufgabenkultur, cognitive engagement). Aufgrund unterschiedlicher konzeptioneller Ansätze stehen empirische Befunde zu konkreten Umsetzungsmerkmalen eines kognitiv aktivierenden Sportunterrichts bislang relativ isoliert und unverbunden nebeneinander. Der Beitrag fragt, welche didaktischen Merkmale sich zur Umsetzung kognitiver Aktivierung im Sportunterricht in empirischen Studien finden und auf welchen konzeptionellen Grundannahmen diese empirischen Studien basieren. In einem Scoping Review kamen deutsch- wie englischsprachige Suchbegriffe, die die aus der Unterrichtsforschung stammende Idee der kognitiven Aktivierung abbilden (z. B. Reflexion, engagement), in unterschiedlichen Datenbanken (z. B. Scopus, ERIC) zum Einsatz. Die Suche ergab 4798 Treffer, von denen 52 Studien in die Analyse einbezogen wurden. Basierend auf fünf konzeptionellen Zielkategorien eines kognitiv aktivierenden Sportunterrichts (z. B. gesundheitsbezogenes Wissen, Spielverständnis und -fähigkeit) wurden neun didaktische Merkmale zur Umsetzung eines kognitiv aktivierenden Sportunterrichts identifiziert (z. B. offene Problemstellungen, Reflexion des sportlichen Handelns). Bei der sportunterrichtlichen Umsetzung dieser Merkmale hatten Sportlehrkräfte mitunter Schwierigkeiten (z. B. bei der Gestaltung von Reflexionsphasen). Weiterer Forschungsbedarf besteht u. a. hinsichtlich der Wirksamkeit eines kognitiv aktivierenden Sportunterrichts.

Resolving the battle of short- vs. long-term AI risks
Authors: Sætra Henrik Skaug , Danaher John 
Published: September 2023

Abstract
AI poses both short- and long-term risks, but the AI ethics and regulatory communities are struggling to agree on how to think two thoughts at the same time. While disagreements over the exact probabilities and impacts of risks will remain, fostering a more productive dialogue will be important. This entails, for example, distinguishing between evaluations of particular risks and the politics of risk. Without proper discussions of AI risk, it will be difficult to properly manage them, and we could end up in a situation where neither short- nor long-term risks are managed and mitigated.

AbstractBackground:Randomized clinical trials (RCT) are the foundation for medical advances, but participant recruitment remains a persistent barrier to their success. This retrospective data analysis aims to (1) identify clinical trial features associated with successful participant recruitment measured by accrual percentage and (2) compare the characteristics of the RCTs by assessing the most and least successful recruitment, which are indicated by varying thresholds of accrual percentage such as ≥ 90% vs ≤ 10%, ≥ 80% vs ≤ 20%, and ≥ 70% vs ≤ 30%.Methods:Data from the internal research registry at Columbia University Irving Medical Center and Aggregated Analysis of ClinicalTrials.gov were collected for 393 randomized interventional treatment studies closed to further enrollment. We compared two regularized linear regression and six tree-based machine learning models for accrual percentage (i.e., reported accrual to date divided by the target accrual) prediction. The outperforming model and Tree SHapley Additive exPlanations were used for feature importance analysis for participant recruitment. The identified features were compared between the two subgroups.Results:CatBoost regressor outperformed the others. Key features positively associated with recruitment success, as measured by accrual percentage, include government funding and compensation. Meanwhile, cancer research and non-conventional recruitment methods (e.g., websites) are negatively associated with recruitment success. Statistically significant subgroup differences (correctedp-value < .05) were found in 15 of the top 30 most important features.Conclusion:This multi-source retrospective study highlighted key features influencing RCT participant recruitment, offering actionable steps for improvement, including flexible recruitment infrastructure and appropriate participant compensation.
Launching IDeA state early career clinician-scientists with mentored just-in-time grant-writing support
Authors: Hatchimonji Danielle R. , Alderfer Melissa A. , Riegel Erin L. , Akins Robert E. 
Published: September 2023

Abstract
Institutional Development Award (IDeA) programs build research infrastructure in regions with historically low access to NIH funds. The Mentored Research Development Award (MRDA), a professional development program embedded in our IDeA-funded center, provides junior investigators with mentorship and effort offset to write a grant. We evaluated outcomes from the first eight years (2013–2021; N = 55) using administrative records, publicly available data, and a self-report survey (n = 46, 84% response rate). Fifteen MRDA recipients (27%) went on to receive NIH funding. Providing just-in-time grant-writing support may launch early career clinician-scientists in an IDeA state context.
A set of 2-recurrence whose perfect squares do not form a set of measurable recurrence

AbstractWe say that
$S\subseteq \mathbb Z$
is a set of k-recurrence if for every measure-preserving transformation T of a probability measure space
$(X,\mu )$
and every
$A\subseteq X$
with
$\mu (A)>0$
, there is an
$n\in S$
such that
$\mu (A\cap T^{-n} A\cap T^{-2n}\cap \cdots \cap T^{-kn}A)>0$
. A set of
$1$
-recurrence is called a set of measurable recurrence. Answering a question of Frantzikinakis, Lesigne, and Wierdl [Sets of k-recurrence but not (k+1)-recurrence. Ann. Inst. Fourier (Grenoble)56(4) (2006), 839–849], we construct a set of
$2$
-recurrence S with the property that
$\{n^2:n\in S\}$
is not a set of measurable recurrence.
The “glitch” of Rabia monuments: a semiotic analysis of July 15 monuments in Turkey
Authors: Üngür Erdem 
Published: September 2023

AbstractAfter the coup attempt on July 15, 2016, the Turkish state started to produce a new official history of the event as a narrative of popular resistance against a military coup for the sake of democracy. This narrative with a religious aura was supported by “democracy watch” meetings and new commemoration days, museums, and monuments across Turkey. It was based on four concepts, symbolized by theRabiasign: one nation, one homeland, one flag, and one state. However, the use of the Rabia sign has fallen from grace recently, creating a critical gap or “glitch” in the mnemonic infrastructure. This paper offers a visual categorization of July 15 monuments across Turkey and positions them in the historiography of Turkish national monuments. Finally, Rabia monuments are analyzed as a case study to show part of the complex (trans)national narratives of the “New Turkey.”
Giant panda loan exhibitions in China underdeliver on educating visitors: insights and recommendations for improvements

Published: September 2023

AbstractGiant panda Ailuropoda melanoleuca exhibits are popular attractions for zoos and wildlife parks. However, it remains to be investigated whether such exhibits enhance visitor knowledge about pandas and broader conservation issues. We conducted questionnaire surveys at giant panda exhibits at three city zoos and five wildlife parks in China. Although visitors were generally interested in the giant panda, this was not reflected in their post-exhibit knowledge of giant panda biology. Socio-demographically, men were more knowledgeable of giant panda biology than women. Knowledge correlated positively with respondent level of education. Younger respondents (< 45 years) knew most about giant pandas and expressed an interest in learning more about them using social media. The most informed respondents had visited other giant panda exhibits previously. Respondents were generally satisfied with the giant panda exhibits (mean score 4.44/5). Wildlife parks delivered a better educational outcome than city zoos. We recommend approaches to improve the visitor experience further and to leverage public interest in broader conservation engagement and action in China.
Spartans in the ancient Greek novels
Authors: Jolowicz Daniel 
Published: September 2023

AbstractCharacters in the Greek novels comprise a dizzying array of identities, but one group of people who have received barely any attention are Spartans. They appear only in Chariton of Aphrodisias and Xenophon of Ephesus, where analysis of their presence sheds crucial light on the novels’ literary and sociocultural agendas. After an introduction (section I), section II discusses Chaereas’ self-characterization as the Spartan Leonidas in book 7 of Chariton’sChaereas and Callirhoein the context of Imperial-period Sparta: its institutions (the Leonideia festival), prosopography (the Euryclid dynasty) and reputation for military greatness. I link these elements to the ‘kinsman of Brasidas’ in book 8, who can be directly connected to an Imperial-period descendant of Brasidas in Plutarch’sSayings of Kings and Commanders, as well as to Thucydides’ Brasidas. Section III explores the Spartan identity of Aegialeus and Thelxinoe, the protagonists of an inset story told to Habrocomes in book 5 of Xenophon’sEphesiaca. Details of their lives correspond closely to Spartan cultural phenomena familiar from Plutarch’sLife of Lycurgus, especially in connection with marriage customs. This has consequences for the evaluation of Xenophon as a witty and sophisticated novelist, and for his compositional date. Section IV draws out the significant parallels between the depiction of Spartans in Chariton and Xenophon, which form the basis of proposals regarding their literary and chronological relationships.

Published: September 2023

AbstractThe restrictive measures taken by nursing homes during the COVID-19 outbreak in 2020 (e.g., quarantine) may have been important stressors for which residents needed resilience to safeguard their well-being. Based on 30 semi-structured interviews with nursing home residents and close relatives, this study explored the lived experiences with respect to the restrictive measures. The data were collected in psychogeriatric, somatic, and mixed wards in The Netherlands and Flanders, Belgium. The restrictive measures were important stressors for residents, indicated by feelings of loneliness, sadness, and powerlessness. To deal with these measures, residents used various resources, which were determined by factors in the individual (e.g., health), interactional (e.g., possibilities for social interactions) and contextual (e.g. nursing home policy) domains. Because the lived experiences with respect to the restrictive measures seemed to relate to the resilience of nursing home residents, it is crucial to reinforce resources in the individual, interactional, and contextual domains.

Published: September 2023

AbstractThe objective of this study is to prospect ISSR primers (Inter Simple Sequence Repeats) and, further genetic characterization in Paratecoma peroba. For this, leaf samples of 20 individuals were collected in a forest fragment, located in a private area, close to the Instituto Federal de Educação, Ciência e Tecnologia do Espírito Santo, in the city of Alegre, ES, Brazil. For this, 43 ISSR primers were tested, and 10 primers were selected, which provided a total of 91 bands, with 57 polymorphic bands, resulting in 62.63% polymorphism. The polymorphic information content (PIC = 0.27) indicated moderate informativeness of the primers and, therefore, they are efficient in studies with the species. However, the values found for genetic parameters such as the number of observed (AO = 1.68) and effective (AE = 1.41) alleles and, the genetic diversity indices of Nei (H* = 0.23) and Shannon (I* = 0.35) indicate the occurrence of homozygous loci and low genetic diversity in the population. On the other hand, the genetic structure evaluated by the Bayesian approach revealed the formation of three genetic groups distributed in all sampled individuals, inferring once again about the occurrence of loci in homozygosity. Therefore, the connection of neighbouring fragments and the establishment of individuals obtained from other sources could increase the genetic diversity of the population and reduce the possible effects of depression by inbreeding and genetic drift.

Published: September 2023

AbstractIn Iran, monochoria is a noxious weed in fields of transplanted rice. Two field experiments were conducted to assess the efficacy of soil-applied and foliar-applied herbicides to control monochoria in transplanted rice. Prepackaged herbicides (triafamone plus ethoxysulfuron applied at 40 g ai ha−1, pyrazosulfuron-ethyl plus pretilachlor applied at 382.5 g ai ha−1, and pendimethalin plus clomazone applied at 1,200 g ai ha−1) reduced monochoria biomass by 100%, 100%, and 14%, respectively; and a single application of flucetosulfuron at 30 g ai ha−1, pendimethalin at 990 g ai ha−1, thiobencarb at 2,750 g ai ha−1, and pretilachlor at 1,000 g ai ha−1 reduced monochoria biomass by 100%, 99%, 75%, and 56%, respectively, compared with a nontreated control. Tank-mixed bensulfuron-methyl at 45 g ai ha−1 applied with pretilachlor, thiobencarb, or pendimethalin provided 100% control of monochoria. Rice height, and straw and grain yield were greater after herbicide treatments than those of the nontreated and hand-weeded controls, indicating the advantages of chemical control of monochoria over manual weeding. Full-season monochoria interference reduced rice grain yield by 32%. In the second study, the herbicides triafamone plus ethoxysulfuron, flucetosulfuron, 2,4-D at 1,080 g ai ha−1, dicamba plus 2,4-D at 928 g ai ha−1, bispyribac-sodium at 31.25 g ai ha−1, bentazon plus MCPA at 1,150 g ai ha−1, pyribenzoxim at 30 g ai ha−1, and propanil at 5,400 g ai ha−1 applied to foliage at 4- to 5-leaf seedlings of monochoria provided ≥97% control and prevented 100% of its regrowth, with the exception of propanil. This study shows that monochoria control can be achieved by using a variety of residual and foliar-applied herbicides with different mechanisms of action.

Published: September 2023

Abstract: Background: Feedback is considered one of the most important strategies in psychotherapy training. Objective: We investigated the effect of competence feedback on therapist self-perceived competence, professional self-confidence, and tendency to self-disclosure in supervision. Method: Master-level psychotherapy trainees ( N = 67) were randomly assigned to a competence feedback group (CFG) or a control group (CG). Trainees in CFG repeatedly received feedback regarding their therapeutic competencies during cognitive behavioral therapy for 114 patients with a major depressive disorder. Feedback was provided by licensed psychotherapists, based on video tapes of the treatments. Trainees’ therapeutic competencies, professional self-confidence, and tendency to self-disclosure in supervision were evaluated by self-report questionnaires. Results: Self-perceived competence improved significantly more in the CFG than in the CG. Professional self-confidence improved overall, but no differences between CFG and CG were found. Self-disclosure did not change significantly in general. Conclusion: We conclude that specific training strategies are necessary for achieving specific training aims.
Observations of Internal Tides at the Vitória‐Trindade Ridge, South Atlantic Ocean

Published: September 2023

AbstractThe Vitória‐Trindade Ridge (VTR) has been shown, based on satellite altimetry, to be an important region for the generation of internal tides (ITs) that radiate southward and northward into the South Atlantic Ocean. Here, nearly 1 year of unprecedented high‐density in situ velocity and temperature data collected at this undersampled region, were used to investigate and quantify the IT properties and variability. About 90% of the total tidal energy can be accounted for by the IT in the semidiurnal band. The data depict a dominant surface‐intensified mode‐1 vertical structure associated with progressive baroclinic waves, with a less prominent mode‐2 growing in importance from January to June. Values of energy conversion from the barotropic to the baroclinic semidiurnal tides are comparable to other important sites of IT generation in the world ocean. Energy conversion and the highly coherent energy fluxes are strongly related with the spring‐neap cycle, indicative that the observed IT are predominantly generated at the observational site. Fluxes and conversion are modulated by significant changes in the vertical stratification of the upper ocean, which are observed to occur during the different months of observations.
Parametrization of Energetic Ion and Electron Fluxes in the Near‐Earth Magnetotail

Published: September 2023

AbstractThe near‐Earth plasma sheet region is the main source of energetic (tens to hundreds keV) ion and electron populations transported by convection and injections into the inner magnetosphere. Energetic ions from the plasma sheet contribute to the ring current, whereas energetic electrons contribute to the radiation belt seed population for further acceleration to relativistic energies. Near‐Earth plasma sheet energetic fluxes have been traditionally used to set boundary conditions for radiation belt and ring current models. This study provides an empirical parametrization for ∼75 keV flux intensity as a function of the geomagnetic activity index auroral electrojet and the equatorial magnetic field Bz. Such parametrization includes the dynamic magnetic field configuration in the near‐Earth plasma sheet and may be merged with empirical magnetic field models. We also provide models extending this parametrization to the [20, 300] keV of electron energy range and [75, 300] keV of ion energy range. The parametrization is developed based on THEMIS and Geostationary Operational Environmental Satellite measurements, and verified by comparison with MMS measurements in the near‐Earth plasma sheet. This parametrization incorporates meso‐scale transient flux variations associated with Bz perturbations into ring current and radiation belt simulations.

AbstractUsing Arase observations of the inner magnetosphere during 26 CIR‐driven geomagnetic storms with minimum Sym‐H between −33 and −86 nT, we investigated ring current pressure development of ions (H+, He+, O+) and electron during prestorm, main, early recovery and late recovery phases as a function of L‐shell and magnetic local time. It is found that during the main and early recovery phase of the storms the ion pressure is asymmetric in the inner magnetosphere, leading to a strong partial ring current. The ion pressure becomes symmetric during the late recovery phase. H+ ions with energies of ∼20–50 keV and ∼50–100 keV contribute more to the ring current pressure during the main phase and early/late recovery phase, respectively. O+ ions with energies of ∼10–20 keV contribute significantly during main and early recovery phase. These are consistent with previous studies. The electron pressure was found to be asymmetric during the main, early recovery and late recovery phase. The electron pressure peaks from midnight to the dawn sector. Electrons with energy of <50 keV contribute to the ring current pressure during the main and early recovery phase of the storms. Overall, the electron contribution to the total ring current is found to be ∼11% during the main and early recovery phases. However, the electron contribution is found to be significant (∼22%) in the 03–09 MLT sector during the main and early recovery phase. The results indicate an important role of electrons in the ring current build up.
