Authors: Brenne Silke , Gaertner Bettina , Herrmann Markus 
Published: February 2023

Zusammenfassung
Hintergrund
Das Institut für Allgemeinmedizin der Medizinischen Fakultät Magdeburg bietet im Querschnittsbereich Q7 „Medizin des Alterns und des alten Menschen“ im 5. Studienjahr eine Lehrveranstaltung an, an der neben Disziplinen der Universitätsmedizin gemeindenahe Einrichtungen beteiligt sind. Hospitationen in stationären und kommunalen Einrichtungen werden in Seminaren vorgestellt; alterstypische Syndrome, Erkrankungen und der besondere Umgang mit Diagnostik, Behandlung und Betreuung anhand von Instant-Aging-Einheiten und Gruppenübungen vertieft. Begleitende Vorlesungen ergänzen das Konzept.

Methoden
Die institutsinterne Lehrevaluation erfolgte anhand standardisierter Paper-Pencil-Fragebögen mit 14 Items (Wintersemester [WiSe] 2017/18 und 2018/19). Der Rücklauf betrug im WiSe 2017/18 etwa 95 % und im WiSe 2018/19 etwa 85 %. Die Auswertung erfolgte deskriptiv; die Freitextangaben wurden inhaltsanalytisch ausgewertet.

Ergebnisse
Im WiSe 2017/18 (n = 170) lag das Gesamturteil auf einer 5‑stufigen Notenskala bei 2,73 (Standardabweichung [SD] 0,922) und im WiSe 2018/19 (n = 156) bei 2,58 (SD 0,831). Positiv wurden der Besuch der Hospitationsstätten, die aktive Mitgestaltung der Seminare sowie die Instant-Aging-Einheiten beurteilt. Aufgrund der Kombination unterschiedlicher Lehrformate zeigten sich zunächst inhaltliche Redundanzen, die zum WiSe 2018/19 überarbeitet wurden. Der Wunsch nach weiteren praktischen Übungen sowie der Einbeziehung von sozialrechtlichen Aspekten wurde umgesetzt.

Schlussfolgerungen
Die Kombination aus Vorlesung, Hospitation und Seminar ermöglicht einen interaktionellen Theorie-Praxis-Transfer sowie eine Selbst- und Peer-Reflexion. Praxisnahe Fallvignetten und das in verschiedenen Hospitationsstätten Erlebte bieten Raum für interaktionellen Austausch in den Seminaren, sodass relevante medizinische und psychosoziale Kenntnisse für eine adäquate medizinische Versorgung älterer Patient:innen vermittelt werden.

Zusammenfassung
Hintergrund
Leitlinien (LL) sind ein wichtiges Instrument der Qualitätsförderung – auch in der hausärztlichen Versorgung. Seit Jahren erstellen hochmotivierte Mitglieder der Deutschen Gesellschaft für Allgemeinmedizin und Familienmedizin (DEGAM) meist ehrenamtlich methodisch anspruchsvolle hausärztliche Leitlinien oder sind an der Entwicklung interdisziplinärer Leitlinien beteiligt. Der Innovationsausschuss des Gemeinsamen Bundesausschusses (G-BA) schreibt seit 2020 Förderprogramme zur (Weiter‑)Entwicklung von Leitlinien aus.

Ziel der Arbeit
Mit dieser Publikation sollen durch den Innovationsausschuss des G‑BA aktuell geförderte DEGAM-Leitlinienprojekte vorgestellt werden.

Material und Methoden
Die Vorstellung erfolgt durch eine Kurzbeschreibung der geförderten Leitlinien durch die zugehörigen Autoren(gruppen).

Ergebnisse
In der 2. Ausschreibungsrunde des G‑BA zur Förderung medizinischer Versorgungsleitlinien (2021) haben sich 5 Autorenteams der DEGAM um eine Finanzierung für die Förderung beworben und die Förderzusagen erhalten. Bei den geförderten DEGAM-Leitlinien handelt es sich um a) eine neue Leitlinienentwicklung, b) die Updates (Aktualisierung) von 2 bestehenden Leitlinien und c) das Update und gleichzeitige Upgrade einer DEGAM-Leitlinie von S1- auf S3-Niveau sowie die Aktualisierung einer S3-Leitlinie als „living guideline“.

Diskussionen
Leitlinienerstellung ist ressourcenintensiv und fordert ehrenamtliches Engagement. Die G‑BA-Förderung öffnet der DEGAM Möglichkeiten zu Leitlinien(weiter)entwicklungen, die sonst nicht oder nicht als Upgrades erfolgt wären. Um Leitlinienentwicklung voranzubringen, braucht es zusätzliche Förderungen, da die Ressourcen ehrenamtlich motivierter Leitlinienentwickler:innen endlich sind. Die G‑BA-Förderung unterstützt damit auch mittelfristig die Nachwuchsgewinnung von Leitlinienentwickler:innen. Inwiefern diese Nachwuchsförderung nachhaltig ist, wird sich in der Zukunft erweisen.
Bullshit in Politics Pays
Authors: Gibbons Adam F. 
Published: February 2023

AbstractPolitics is full of people who don't care about the facts. Still, while not caring about the facts, they are often concerned to present themselves as caring about them. Politics, in other words, is full of bullshitters. But why? In this paper I develop an incentives-based analysis of bullshit in politics, arguing that it is often a rational response to the incentives facing different groups of agents. In a slogan: bullshit in politics pays, sometimes literally. After first outlining an account of bullshit, I discuss the incentives driving three different groups of agents to bullshit: politicians, the media, and voters. I then examine several existing proposals to combat bullshit in politics, arguing that each will fail because they ignore the relevant underlying incentives. I conclude somewhat pessimistically that a certain amount of bullshit in politics is inevitable.
Identity matters: cancer stem cells and tumour plasticity in head and neck squamous cell carcinoma
Authors: Salem Abdelhakim , Salo Tuula 
Published: February 2023

Abstract
Head and neck squamous cell carcinoma (HNSCC) represents frequent yet aggressive tumours that encompass complex ecosystems of stromal and neoplastic components including a dynamic population of cancer stem cells (CSCs). Recently, research in the field of CSCs has gained increased momentum owing in part to their role in tumourigenicity, metastasis, therapy resistance and relapse. We provide herein a comprehensive assessment of the latest progress in comprehending CSC plasticity, including newly discovered influencing factors and their possible application in HNSCC. We further discuss the dynamic interplay of CSCs within tumour microenvironment considering our evolving appreciation of the contribution of oral microbiota and the pressing need for relevant models depicting their features. In sum, CSCs and tumour plasticity represent an exciting and expanding battleground with great implications for cancer therapy that are only beginning to be appreciated in head and neck oncology.
Building a more robust framework on revisionism: a reply to Lawson and Legrenzi
Authors: Natalizia Gabriele , Termine Lorenzo 
Published: February 2023

AbstractThe comments by Lawson and Legrenzi to our RISP/IPSR article ‘Tracing the modes of China's revisionism in the Indo-Pacific: a comparison with pre-1941 Shōwa Japan’ contribute to moving the debate on revisionism in international politics a step forward. Their notes on the several issues affecting the International Relations understanding of the phenomenon are on the same page as ours and we appear to share similar doubts and a like-minded curiosity on the subject. While grasping some key topics and shedding light on crucial shortcomings in the literature on international change, power transitions and international order, however, their observations do not come unproblematic. In this reply to their timely remarks, we highlight the perks of their argument but also stress how this falls through in providing a complete framework to understand revisionism in international politics.
ELIMINATION OF IMAGINARIES IN ORDERED ABELIAN GROUPS WITH BOUNDED REGULAR RANK
Authors: VICARÍA MARIANA 
Published: February 2023

AbstractIn this paper we study elimination of imaginaries in some classes of pure ordered abelian groups. For the class of ordered abelian groups with bounded regular rank (equivalently with finite spines) we obtain weak elimination of imaginaries once we add sorts for the quotient groups
$\Gamma /\Delta $
for each definable convex subgroup
$\Delta $
, and sorts for the quotient groups
$\Gamma /(\Delta + \ell \Gamma )$
where
$\Delta $
is a definable convex subgroup and
$\ell \in \mathbb {N}_{\geq 2}$
. We refer to these sorts as the quotient sorts. For the dp-minimal case we obtain a complete elimination of imaginaries if we also add constants to distinguish the cosets of
$\ell \Gamma $
in
$\Gamma $
, where
$\ell \in \mathbb {N}_{\geq 2}$

Evaluation of alternative conservation strategies for the blue-billed curassow Crax alberti in the Middle Magdalena Valley, Colombia
Authors: Valencia Igor F. , Kattan Gustavo H. , Valenzuela Leonor , Caro Lina , Arbelaez Fernando , Forero-Medina German 
Published: February 2023

AbstractThe blue-billed curassow Crax alberti is an endemic Colombian species categorized as Critically Endangered on the IUCN Red List because of the effects of hunting and habitat loss. Conservation and management actions are required to ensure its persistence in the forest remnants across its range. We conducted a population viability analysis for a population in the municipality of Yondó, Antioquia, based on data collected in the field and available information on the reproductive ecology of the species. We evaluate seven realistic conservation scenarios by comparing the effects that changes in mortality from hunting, carrying capacity and initial population size have on the survival probability of the population. Our results indicate that: (1) the studied population is not viable over a 100-year period under current conditions; (2) mortality as a result of hunting and the size of the initial population have the greatest impacts on the mean time to extinction; (3) a strategy based on eliminating hunting in the two sites with the largest forest remnants in the landscape could ensure the viability of the population over a 100-year period; and (4) other strategies (i.e. population supplementation with captive-bred individuals, reduction of deforestation in the landscape) do not guarantee the viability of the population if mortality from hunting remains constant, even at low levels. These results confirm the susceptibility of the blue-billed curassow to the threats it faces in this landscape, particularly hunting, and provide information on the conservation actions that could allow this remaining population to prevail in the long term.
To be or not to be like Iceland? (Ontological) Politics of comparison in Greenlandic tourism development
Authors: Ren Carina , Jóhannesson Gunnar Thór 
Published: February 2023

AbstractIn this article, we introduce the concept ofpolitics of comparisonin tourism development, looking at how comparison contributes to shaping and making sense of tourism development in Greenland. Decision makers and operators in Greenland foresee tourism growth as new transatlantic airports are set to open by 2024. To navigate an uncertain tourism future, many look towards neighbouring Iceland, who experienced exponential growth in international tourism arrivals between 2010 and 2018. In this North Atlantic reflection, comparison also works as a tool to understand tourism, positioning Greenland as a potential destination and deliberating about the future of tourism in the region, while also bringing forth competing logics and trajectories of development. Thus, comparison serves to engage with the meaning and value of tourism, seeing it not only as a pillar of the economy but also as a force affecting landscapes and communities. We argue that the comparisons made by tourism actors work epistemologically – creating knowledge of ‘what is’ – as well as ontologically, forcefully interfering with and producing tourism realities.
Low-cost depth/IMU intelligent sensor fusion for indoor robot navigation
Authors: Alkhawaja Fares , Jaradat Mohammad A. , Romdhane Lotfi 
Published: February 2023

AbstractThis paper presents a mobile robot platform, which performs both indoor and outdoor localization based on an intelligent low-cost depth–inertial fusion approach. The proposed sensor fusion approach uses depth-based localization data to enhance the accuracy obtained by the inertial measurement unit (IMU) pose data through a depth–inertial fusion. The fusion approach is based on feedforward cascade correlation networks (CCNs). The aim of this fusion approach is to correct the drift accompanied by the use of the IMU sensor, using a depth camera. This approach also has the advantage of maintaining the high frequency of the IMU sensor and the accuracy of the depth camera. The estimated mobile robot dynamic states through the proposed approach are deployed and examined through real-time autonomous navigation. It is shown that using both the planned path and the continuous localization approach, the robot successfully controls its movement toward the destination. Several tests were conducted with different numbers of layers and percentages of the training set. It is shown that the best performance is obtained with 12 layers and 80% of the pose data used as a training set for CCN. The proposed framework is then compared to the solution based on fusing the information given by the XSens IMU–GPS sensor and the Kobuki robot built-in odometry solution. As demonstrated in the results, an enhanced performance was achieved with an average Euclidean error of 0.091 m by the CCN, which is lower than the error achieved by the artificial neural network by 56%.
Affiliated Associations in China's Education Sector: Between Passive Autonomy, Discretion and Control
Authors: Gao Hong , Tyson Adam 
Published: February 2023

AbstractUnder President Xi Jinping, the strengthening of the Chinese Communist Party's political control occurs in conjunction with an evolving administrative role for government-affiliated associations. Analysing associations that are subordinate within China's strict hierarchy but which have degrees of operational freedom yields insights into the changing nature of public service and administration in China. Evidence from 63 interviews conducted from 2018 to 2022 with government departments and affiliated associations in the education sector reveals the complexity of state control and degrees of constrained autonomy achieved by affiliated associations. The government exerts control over financing, personnel appointments and core business activities but, over time, associations gain varying degrees of operational autonomy to influence the education agenda and fill gaps in public services. The interdependency and relational variance we find in the case of Ministry of Education-affiliated associations contributes to broader understandings of the complex and fragmentary nature of the Chinese state and public administration.
Parenting knowledge and parenting self-efficacy of mothers with borderline personality disorder and depression: “I know what to do but think I am not doing it”
Authors: Eyden Julie , MacCallum Fiona , Bornstein Marc H. , Broome Matthew , Wolke Dieter 
Published: February 2023

AbstractBorderline personality disorder (BPD) is a complex mental health condition often associated with previous childhood adversity including maladaptive parenting. When becoming a parent themselves, mothers with BPD have difficulties with various parenting cognitions and practices, but unknown is whether they have appropriate knowledge of sensitive parenting. This study explored whether differences in parenting knowledge or self-efficacy are specific to BPD or also found in mothers with depression, and whether symptom severity or specific diagnosis better explain parenting perceptions. Mothers with BPD (n = 26), depression (n = 25) or HCs (n = 25) completed a Q-sort parenting knowledge task and a parenting self-efficacy questionnaire. Results showed mothers with BPD had the same knowledge of sensitive parenting behaviors as mothers with depression and healthy mothers. Self-reported parenting self-efficacy was lower in mothers with BPD and depression compared with healthy mothers, with symptom severity most strongly associated. A significant but low correlation was found between parenting self-efficacy and knowledge. Findings suggest that mothers with BPD and depression know what good parenting is but think they are not parenting well. Mental health difficulties are not associated with parenting knowledge, but symptom severity appears to be a common pathway to lower parenting self-efficacy. Future interventions should test whether reduction of symptom severity or positive parenting feedback could improve parenting self-efficacy.

Published: February 2023

SummaryIn recent years, the incidence of teratospermia has been increasing, and it has become a very important factor leading to male infertility. The research on the molecular mechanism of teratospermia is also progressing rapidly. This article briefly summarizes the clinical incidence of teratozoospermia, and makes a retrospective summary of related studies reported in recent years. Specifically discussing the relationship between gene status and spermatozoa, the review aims to provide the basis for the genetic diagnosis and gene therapy of teratozoospermia.
A Smaller Greater India and a Middle‐Early Eocene Collision With Asia
Authors: Jin Shuchen , Sun Xinxin , Jing Xianqing , Zhang Zijian , Zhang Xiang , Yang Zhenyu 
Published: February 2023

AbstractWhen and how the collision between India‐Asia occurred continue to be debated. We report new paleomagnetic data (Ds = 158.8°, Is = 7.8°, ks = 81.3, α95 = 5.1°, N = 11 sites) from limestone of the Zongpu Formation Member I in the Tingri, which indicate that the Tethyan Himalaya was situated at 3.9 ± 2.6°S during 62‐59 Ma. This implies that Greater India was ∼900 km and that Tethyan Himalaya did not break off from India, which left a ∼2,000 km Neo‐Tethys Ocean that challenges the prevailing hypothesis that the initial collision of India–Asia occurred during this period. The drift rate of the India plate, with an average rate of 160 ± 28 mm/a during 60‐50 Ma, implies that the northern margin (e.g., the Tingri, Gyangze, Gamba, and Zanskar areas) of Greater India almost simultaneously collided with Asia at ∼50 Ma, quasi‐synchronously, and closing the Neo‐Tethys Ocean.
Strategy to Enhance Geological CO2 Storage Capacity in Saline Aquifer
Authors: Li Songyan , Wang Peng , Wang Zhoujie , Cheng Hao , Zhang Kaiqiang 
Published: February 2023

AbstractGeological CO2 storage is an emerging topic in energy and environmental community, which is, as a commonly accepted sense, considered as the most promising and powerful approach to mitigate the global carbon emissions during the transition to net‐zero. Of the geological media which initially considered cover the saline aquifers, oil and gas reservoirs, coal beds, and potentially basalts, up to now only the first two choices have been proven to be the most capable storage sites and successfully implemented at pilot/commercial scales. Here, two tandem papers propose novel strategies for the first time, by synthesizing and utilizing new high‐dryness CO2 foam, to enhance geological CO2 storage capacity in saline aquifer and oil and gas reservoirs. In this paper, a new high‐dryness CO2 foam is synthesized and injected into the saline aquifers to explore the storage capacity enhancement, with the unique foam‐induced advantages of sweep area expansion and storage efficiency improvement. Such a new idea is specifically evaluated and validated through a series of static analytical and dynamic performance experiments. With the optimum surfactant concentration of 0.5 wt%, the foaming volume and quality are determined to be 521 mL and 80.81%, respectively, which also shows excellent salt tolerance with 45,000 ppm Na+, 25,000 ppm Ca2+, and 25,000 ppm Mg2+. Moreover, the water consumption for CO2 storage decreases from 464.31 g/mol at 25% foam quality to 67.38 g/mol at 85% foam quality by using the new CO2 foam. Overall, the newly synthesized CO2 foam could effectively enhance geological CO2 storage capacity and concurrently diminish water consumption, therefore realizing the win‐win environment and economic benefits.

Published: February 2023

AbstractIn this study, the first high‐resolution regional ionospheric model over Africa and adjacent areas (−40–40°N latitude, 30°W–60°E longitude, and 80–1,400 km in altitude) is constructed by assimilating ground‐based slant total electron content (STEC) from 40 GPS (Global Positioning System) receiver stations and space‐based NmF2 (ionospheric F2 peak density) data from C2 (Constellation Observing System for Meteorology, Ionosphere, and Climate‐2) into the International Reference Ionosphere (IRI‐2016) model. An Ionospheric Data Assimilation Four‐Dimensional (IDA4D) technique was used to estimate electron densities as high as 1.5° 3° in latitude and longitude, 10 km in altitude in the E and F regions, and 15 min in universal time. Two experiments were run for the following data sets: (a) GPS‐STECs only and (b) GPS‐STECs and NmF2s from C2 during geomagnetically quiet (6–11 May 2021) and storm periods (12–14 May 2021). The IDA4D assimilation results are validated using independent C2 control group, ionosonde, and JASON‐3 observations. Results for the storm period show that experiment 2 reduces the average root‐mean‐square error (RMSE) of NmF2, foF2, and VTEC by 34%, 31%, and 34%, respectively, and increases the associated correlations by 10%, 14%, and 2% over IRI, respectively. Using IDA4D, we observed enhancement of the northern crest equatorial ionization anomaly in the late evening that was caused by upward and northward plasma transport.
Thermal Electron Heat Fluxes Associated With Precipitated Auroral Electrons During the Saint Patrick's Days 2013 and 2015 Geomagnetic Storms
Authors: Khazanov George V. , Chen Margaret W. , Mishin Evgeny V. , Chu Mike 
Published: February 2023

AbstractThe Rice Convection Model‐Equilibrium (RCM‐E) and SuperThermal Electron Transport (STET) are combined to investigate electron heat flux formation in the region of the diffuse aurora for the geomagnetic storms of 17 March 2013 and 17 March 2015. The primary electron precipitation into the atmosphere resulting from wave particle scattering in the magnetosphere are simulated by the magnetically and electrically RCM‐E during these two geomagnetic storms. The primary precipitating electron fluxes are modified by the STET model by taking into account atmospheric backscatter processes. The modified electron energy fluxes and their mean energies are coupled to the STET code to calculate electron thermal fluxes associated with diffuse aurora on a global scale. We use the simulated heat flux to estimate electron temperatures at the upper ionospheric altitudes and compare them with corresponding observations from the Defense Meteorological Satellite Program satellite.
