Background. Recently, to assess the physiological cardia in esophageal achalasia (EA), the method of endoscopic ultrasonography (EUS) has been used, which combines the capabilities of two studies, endoscopic and ultrasound, in addition to traditional diagnostic methods, radiography and endoscopy, and allows detecting structural changes in the esophageal wall and lower esophageal sphincter (LES). Objective: to determine the role of endoscopic ultrasonography in assessing the state of phy­siological cardia in esophageal achalasia. Materials and methods. In the Department of Digestive Surgery of the SI “Institute of Gastroenterology of the National Academy of Medical Sciences of Ukraine” in 2023–2024, according to the objectives of the study, 15 patients with EA and 20 practically healthy individuals (control group) were examined. All patients underwent X-ray and endoscopic examination of the oesophagus, stomach, duodenum, and EUS. Results. Videoesophagogastroduodenoscopy revealed changes characteristic of EA: dilation of the esophageal diameter (100.0 %), stagnant contents in the esophageal lumen (66.7 %), resistance to the passage of an endoscope through LES (86.7 %). X-ray revealed EA stage I in 13.3 % of cases by peristalsis and esophageal diameter, stage II — in 33.3 %, stage III — in 46.7 %, and stage IV — in 6.7 % of cases. When performing EUS, the esophageal hiatus was 19.29 mm (normal 23–36 mm); the eso­phageal wall thickness in the middle third was 6.76 mm (normal < 3 mm); the LES wall thickness was 6.02 mm (normal < 5 mm). To detect fibrotic changes in the esophageal and the LES wall, compression elastography was used. This method helped reveal a significant thickening of the internal circular muscle of the LES from 2.5 to 4.5 mm in 46.6 % of cases, and in 26.6 %, with EA stage III and IV, fibrotic changes were detected in the lower third of the esophageal wall. Conclusions. It has been found that EUS in EA answers questions that are not answered by traditional research methods, namely, it makes it possible to assess a number of parameters (thickness of the walls of the LES and the lower third of the esophagus, diameter of the esophageal hiatus) and identify structural changes (the presence of fibrosis), which significantly affects the choice of a method for a surgical correction of physiological cardia in EA.

A challenge in diagnosis and treatment in asthma patients with allergic bronchopulmonary aspergillosis: a review
Authors: Lukito Elizabeth Feloni , Chandra Valencia , Danessa Gabriela , Wijaya Meiliyana
Published: June 2024

Allergic bronchopulmonary aspergillosis (ABPA) is a common form of fungal-related asthma disease mainly caused by Aspergillus fumigatus. The increasing prevalence of asthma globally and the characteristic of Aspergillus are very easily dispersed in the air to inhale, leading to increased cases of ABPA in asthma patients. Inhalation of conidia Aspergillus spp. can trigger asthma exacerbations due to poor mucociliary clearance. However, the exact pathogenesis is still unclear. Clinical features commonly found in ABPA patients are productive cough with dark green or brown mucus or even hemoptysis. Several criteria for establishing the diagnosis of ABPA can be based on clinical features, laboratory examinations, and imaging, but none has become the gold standard. However, the primary laboratory test utilized for ABPA screening is the measurement of serum-specific IgE levels to A. fumigatus, owing to its high sensitivity. Despite the challenges in finding the most fitting universal consensus, most clinicians still follow the criteria proposed by Rosenberg et al. in 1977. The recommended ABPA treatment is prednisone and/or azole antifungal agents such as itraconazole. In addition, the potential of monoclonal antibodies in ABPA therapy is still under further research. Long-term diagnosis and treatment delays can lead to complications such as bronchiectasis and fibrosis. This review aimed to highlight ABPA in asthma patients, from etiopathogenesis to managing the disease
CORRELATION BETWEEN FETAL BIOMETRY AND FETAL TRANSVERSE CEREBELLAR DIAMETER IN DETERMINATION OF GESTATIONAL AGE FROM THE 15TH WEEK OF GESTATION TO TERM IN HEALTHY WOMEN WITH UNCOMPLICATED PREGNANCY
Authors: KAUR AMANJEET , KUMARI AMITA , SUMAN YADAV , PARASDEEP KAUR
Published: June 2024

Objectives: The present study was conducted as an attempt to determine a correlation between the transverse cerebellar diameter (TCD) and the gestational age (GA) as determined by the last menstrual period (LMP) and other sonographic parameters such as biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), and femur length (FL) in healthy women with uncomplicated pregnancy between the 15th week of gestation to term, to derive normogram for estimating the GA of the fetus from ultrasonographically measured transverse cerebellar diameter.
Methods: This prospective study was conducted on 1040 healthy women with uncomplicated pregnancy between the 15th week of gestation to term. Correlation between the GA by LMP with GA by other ultrasound parameters was done using Karl Pearson’s correlation(r).
Results: This study demonstrated that throughout 15–40 weeks, TCD showed a strong correlation with clinical GA with a correlation coefficient (r) of 0.967 and a statistically significant correlation. Correlation coefficients between TCD and BPD, TCD and HC, TCD and AC, and TCD and FL being 0.987, 0.987, 0.986, and 0.988, respectively, indicated statistically significant and very strong correlation. Normogram of TCD showed that there was a linear relationship between cerebellar growth and gestational age.
Conclusion: TCD can be used as a reliable parameter for the determination of GA.

Objective: The present study aims at describing the clinical features, laboratory diagnosis, and complications in patients presenting with febrile illness due to scrub typhus and dengue coinfection from Southern Rajasthan, India.
Method: This present prospective, observational, and hospital-based study conducted in the Department of Microbiology of AIMS & RC, Rajsamand, located in Southern Rajasthan, from January 2021 to December 2021. Scrub typhus was diagnosed in the microbiology laboratory by performing SD Bioline, one-step scrub typhus for the detection of IgM antibody, and dengue fever using J.mitra and Co. Pvt. Ltd., rapid card test for the detection of NS1 antigen and IgM antibody.
Result: Out of 500 patients suspected of AUFI, 25 (5%) patients diagnosed of having dengue and scrub typhus coinfection. Fever was present in all 25 (100%) patients and 13 (52%) of patients had arthralgia, nausea, and vomiting. The most common sign noticed in our study was pallor and icterus in 10 (40%) patients each followed by shock/hypotension in 8 (32%) and hepatosplenomegaly in 5 (20%). The most predominant laboratory finding was thrombocytopenia (<1.0 × 106/cumm) in 23 (92%) patients, while elevated bilirubin (>2 mg/dl) in 22 (88%) and elevated transaminase and prolonged aPTT in 21 (84%) patients each. The majority of patients 23 (92%) had hepatic dysfunction, i.e., in followed by multi-organ dysfunction (MODS) in 15 (60%).
Conclusion: In developing countries like India, particularly in tropical areas, dengue, and scrub typhus coinfection is under-recognized entity. Additional investigation should be carried out in cases of AUFI patients with features such as hypotension, leukocytosis, early drop in platelet counts, and hypoalbuminemia.
ROLE OF ULTRASONOGRAPHY IN RESPONSE ASSESSMENT FOLLOWING NEOADJUVANT CHEMOTHERAPY IN LOCALLY ADVANCED BREAST CARCINOMA: EXPERIENCE FROM A TERTIARY CARE CENTER
Authors: BIDYUT BISWAS  , MD ASIF ALI  , ARABINDA ROY  , BISWAS LINKON
Published: June 2024

Objective: Neo-adjuvant chemotherapy (NACT) has a pivotal role in the treatment of locally advanced breast carcinoma (LABC). In this study, we assess the efficiency of ultrasound in the response assessment of NACT in patients with LABC using RECIST criteria and its correlation to the final histopathological report.
Methods: 40 patients with LABC underwent clinical examination and ultrasonography (USG) of the bilateral breast and axilla before starting NACT. After receiving three cycles of NACT, a repeat USG and clinical examination were done to assess the response to chemotherapy. Patients with responsive disease underwent radical surgery, and we correlate the findings of histopathological examination (HPE) with those of post-NACT USG findings.
Results: After three cycles of NACT, clinical examination showed a complete response in 15 (37.5%) patients and a partial response in 21 (52.5%) patients. While USG detected a complete response in 8 (20%) patients and a partial response in 28 (70%) patients, seven patients, in whom clinical examination did not find any disease, were detected by USG. HPE showed a complete pathological response in 5 specimens, and in the rest of 31 cases, HPE revealed a residual tumor. USG did not miss any of the pCR cases but overestimated CR cases by 9% (3 patients). On the other hand, all partial response diagnoses by USG were acknowledged by HPE.
Conclusion: To conclude, it can be said that USG can be used as an effective radiological tool for response assessment and subsequent treatment decisions, especially in places where there is a lack of infrastructure and affordability.

Published: June 2024

Objectives: The study aimed to assess follicle-stimulating hormone (FSH), luteinizing hormone (LH), prolactin, and thyroid-stimulating hormone in obese patients with primary infertility and early pregnancy loss (EPL) and compare with normal fertile patients.
Methods: Patients were divided into two groups. Group A consists of 50 patients with a history of infertility and EPL with a body mass index of more than 30 kg/m2. Group B consists of 50 normal fertile patients. Informed written consent was taken from all the patients. Blood samples were taken and hormone levels in two groups were measured and compared statistically.
Results: Comparison and statistical analysis of FSH levels in obese infertile and normal fertile groups showed the difference to be statistically highly significant. LH levels in both groups were statistically highly significant. When compared statistically, the difference between prolactin levels of both groups was highly significant.
Conclusion: This study supports the impact of obesity on infertility and pregnancy outcomes. Obesity affects dysfunction of the hypothalamus, pituitary ovarian axis, and results in a higher risk of infertility and EPL.

Authors: BENKE SAMIKSHA , KORE PADMAJA SANTOSH
Published: June 2024

This article examines the management of varicose vein disease, a condition affecting lower limbs and characterized by swollen, convoluted veins. It highlights that prolonged standing and obesity, particularly in older adults, increase the likelihood of varicose vein disease. It provides a comprehensive analysis of treatment options and preventative strategies. The review discusses varicose veins, their causes, prevention methods, risk factors, and treatments. It highlights the effectiveness of endovascular, surgical, and herbal therapies in improving quality of life and reducing secondary vein-related issues. Lifestyle interventions like consistent yoga and certain fruits and vegetables are also emphasized as preventative strategies. The article emphasizes the importance of antioxidant medications, particularly flavonoid-based ones, in reducing arterial blood pressure and preventing atherosclerosis in patients with varicose veins. These veins, typically found in the thigh or calf, are enlarged due to sensitivity to the venous wall and abnormal valve function. Over time, they may become longer, twisted, pouched, and thicker due to gravity pulls.

Authors: Jitendra Hotwani  , Ankita Rao
Published: June 2024

Objective: National regulatory authority reviewed various fixed-dose combinations (FDCs) in view of doubtful rationality status and subsequently 349 FDCs were banned in 2018. This study was conducted to analyze the antimicrobial and antidiabetic FDCs banned by the Central Drugs Standard Control Organization in India.
Methods: Data were collected from the report of drugs technical advisory board subcommittee. Banned antimicrobial and antidiabetic FDCs were assessed for the following parameters – number of active pharmacological ingredients, routes of administration and dosage forms, indications for marketing, reasons for banning, and pharmacological group of FDCs.
Results: Seventy antimicrobial and 25 antidiabetic FDCs were analyzed. These FDCs contained 2–7 drugs, available mostly as tablets (51.42%, 100%) in antimicrobial and antidiabetic groups, respectively. Antimicrobial FDCs were marketed most for respiratory tract infections and infection and inflammatory conditions of the skin (17, 24.28% each) while antidiabetic FDCs were marketed for Type 2 diabetes mellitus (14, 56%). The reasons for ban were pharmacodynamic (68.57%, 16%) and pharmacokinetic (20%, 40%) mismatches, lack of evidence of efficacy (7.14%, 36%), and safety concerns (4.28%, 8%) in antimicrobial and antidiabetic groups, respectively. In antimicrobial FDCs, the most common combination was that of an antibacterial with other miscellaneous drugs (like zinc, Vitamin E, serratiopeptidase, etc.) (19, 27.14%) whereas antidiabetic FDCs most commonly had biguanide with thiazolidinedione and sulfonylurea (7, 28%).
Conclusion: There is a need for scrutiny of other FDCs in larger interests of patient care and prescribers should be made aware about recently banned FDCs to promote rational pharmacotherapy.

Published: June 2024

Objective: The study aimed to assess the incidence of hyponatremia in cirrhosis of the liver and to evaluate the association between serum sodium levels and the severity of cirrhosis and its complications.
Methods: Data on inpatients with cirrhosis of the liver were collected on the date of admission. The serum sodium levels on day 1 and the presence of complications and their severity in 100 patients were analyzed.
Results: The incidence of dilutional hyponatremia, which was subdivided into three groups (mmol/L): A-≤130, B-131-135, and C-≥136, were 55%, 25%, and 20%, respectively. The severity of liver cirrhosis was assessed using the CTP score and the MELD score, with a higher score seen in Group A (p=0.011 and p=0.012), respectively. Furthermore in group A, higher grades of complications were seen: grade 3/gross ascites (p=0.001), grade lll/lV hepatic encephalopathy (p=0.007), spontaneous bacterial peritonitis (p=0.049), and hepatorenal syndrome (p=0.022). Even in group B with s.Na+level 131–135 mmol/L, the development of complications was no less common.
Conclusion: Serum sodium levels must be closely monitored in cirrhotic patients as they suggest the possibility of a potentially negative impact on the clinical course of the disease.

El feedback entre iguales y el desarrollo profesional docente: revisión sistemática
Authors: De la Iglesia Begoña , Forteza Dolors , Duma Laura
Published: June 2024

El potencial de la colaboración profesional como mecanismo de desarrollo profesional docente (DPD) radica en las oportunidades de retroalimentación que ofrece. El feedback ha sido ampliamente investigado, pero la mayoría de los estudios se centran en la retroacción que se da en la relación profesor-alumno. En cambio, no se ha encontrado suficiente revisión de la literatura respecto a la retroalimentación profesor-profesor desde una relación simétrica ni se ha analizado su impacto en el DPD. Con base en el protocolo PRISMA, se seleccionaron 30 artículos empíricos revisados por pares de entre los años 2012 y 2022. En concreto, el proceso siguió tres fases: búsqueda de documentos y evaluación mediante la herramienta VOSViewer; selección y filtrado de los documentos bajo criterios definidos, y análisis de los documentos. Los resultados muestran beneficios y dificultades a nivel docente y organizativo. Entre los primeros, destaca que el feedback favorece el aprendizaje del alumnado, la relación entre las parejas docentes y el clima de centro. La principal dificultad identificada se refiere a la falta de competencia del profesorado para ofrecer una retroalimentación de calidad. Pocos artículos analizaron el impacto del feedback en las metodologías de enseñanza y aprendizaje, a pesar de que todos mostraron sus ventajas, y menos aún examinaron su impacto en el DPD. Para finalizar, se sugieren algunas recomendaciones para mejorar la investigación y sus prácticas.
Teacher Perspectives on Breakout Rooms in Online Education in a K-12 Bilingual School in China
Authors: Macur Gregory
Published: June 2024

One key problem when teaching online, is the lack of access to group work and collaboration. This study used two main methods of research, a survey including 4 questions and a 5-point Likert scale with 4 statements, and an interview with a Head of Educational Technology. This was done in a large K-12 bilingual school in Shanghai, China. Some key findings included: 92% of teachers knew what breakout rooms are; almost 3 times the percentage of teachers agreed (59%) that breakout rooms are viable in online learning as opposed to disagreed (17%); double the percentage of teachers disagreed (24%) that breakout rooms are too problematic to use as opposed to agreed (48%); 81% of teachers agreed that they need to know more activities for use with breakout rooms; and 79% of teachers agreed they needed to know how to better expose students to breakout rooms. There was a significant correlation between the Primary and Secondary phases; the interview responses backed up this data and the correlation. The four main fed back methods of using breakout rooms were: Group presentations, Group and pair discussions, Differentiated learning and Group research.
General and Personal Reflections on Succeeding as a Woman Science Researcher
Authors: Utts Jessica
Published: June 2024

In 1991 the Parapsychology Foundation sponsored a conference on Women in Parapsychology. In my paper for that conference (Utts, 1994) I discussed research identifying multiple factors that contributed to gender inequity in research careers in science, with a focus on academia. These factors included cultural norms, institutional barriers to success for women, implicit biases, and social pressures that deterred women from entering and succeeding in careers in science. In the past three decades, progress has been made on some of these factors, but not all of them. The first part of this paper discusses the extent to which the situation has improved (or not) for seven of the factors identified in the earlier paper, citing a combination of research and personal observation. The second part of this paper discusses multiple avenues of research showing the impact of subtle influences throughout childhood and early adulthood on career success. For example, cultural norms depicting scientists as men have gradually improved over the years, but children are still more likely to draw a man than a woman if asked to draw a scientist. Role models, as well as encouraging mentors, are important factors in determining whether a woman will pursue a career in science. Many successful women in science can identify a single mentor whose encouragement was a major contributing factor to her success. A sense of meaning in ones‘ work, and a supportive community are additional factors contributing to success. The final part of the paper is autobiographical, illustrating how the factors documented by this body of research played a role in my life. In a narrative starting from childhood and continuing through my career, I identify individuals and circumstances that contributed to my success. One significant factor was the welcoming parapsychological community, and details of how I was led to work with that community are discussed. The paper provides suggestions for specific actions that individuals and communities can take to encourage more women to succeed in careers in science, including in parapsychology.
Wanted: The Poltergeist
Authors: Huesmann Monika , Schriever Friederike
Published: June 2024

54 RSPK reports of the Freiburg Institute for Frontier Areas of Psychology and Mental Health (IGPP) from 1947 to 1986 were analyzed quantitatively-statistically. A specially developed questionnaire was used to collect the most detailed information possible on the reported phenomena, the poltergeist victims, the focal person, the witnesses, and the investigation and documentation. While Part 1 of this evaluation is devoted to the phenomenology of RSPK phenomena in general, Part 2 focuses on poltergeist victims and focus persons (FPs). The comparison to the phenomenology of RSPK in existing case collections revealed clear similarities, but also striking differences, e. g., regarding the average duration of poltergeist phenomena. Two factors were found via a factor analysis, which were confirmed by a subsequent cluster analysis. The first factor was called the “novelty factor” or “structure factor,” since it only includes items that point to something that is novel, adds to an earlier situation, or introduces structural changes (e. g., “apports,” “penetration,” “graffiti”). The second factor is called “modification factor” or “behavioral factor,” because it is defined by items that describe modifications in the state of objects present (e. g., “objects suddenly disappear,” “cabinets, doors, windows open by themselves”). The analysis of the data on poltergeist victims and FPs showed that they come from all parts of the population. Subjectively, they feel very much burdened by the poltergeist occurrences. Frequently, they are socially isolated after the outbreak. Once the phenomena have faded away, they strongly tend to repress related recollections. 56￰FPs were male. At the time the phenomena begin, a large number of the FPs are in puberty. One third of the FPs report bodily and psychological peculiarities during or immediately prior to RSPK phenomena. With unusual frequency, they complain about conversion-neurotic symptoms (such as psychologically caused paralysis, narrowing of consciousness, etc.) as well as about “absentes” of psychogenic or neurological origin). There is insufficient documentation to allow decision on the question as to whether these peculiarities are reactions to the RSPK occurrences that might be found in other poltergeist victims as well. FPs are exposed to many social and psychological stress factors. Relatively many of them live with only one parent or with grandparents. Some of the FPs confess to having used fraudulent manipulation. This does not normally imply that presumed paranormal phenomena did not occur. Our data about FPs largely correspond to the ones Roll (e. g., 1977) found in his investigations.

persönlichen Homezone können sie den ÖPNV wie gewohnt nutzen, so wie sie es von klassischen Zeitkarten kennen. Der individuelle Preis wird auf Basis des Durchmessers, der jeweiligen ÖPNV-Angebotsquali-
tät in der Homezone und dem gewählten Zeitraum ermittelt. Für Fahrten außerhalb der persönlichen Homezone lässt sich der neue E-Tarif bequem mit dem elektronischen Entfernungstarif kombinieren.
Die Integration ergänzender Mobilitätsangebote (MaaS) ist ebenfalls möglich.

Authors: Kurz Franz , Mendes Paulo , Runge Hartmut , Gstaiger Veronika
Published: June 2024

Nachweis der Konformität von GNSS-Geräten, insbesondere zur Unterstützung der Funktionen des automatisierten Fahrens in den von der Society of Automotive Engineers (SAE) definierten Stufen L3, L4
und L5 erfolgt bisher über den direkten Vergleich mit hochwertigen GNSS-Geräten, wobei Test- und Referenzdaten den gleichen Qualitätsverlusten aufgrund äußerer Einflussfaktoren unterliegen. Der neu
entwickelte und unter realen Bedingungen getestete Ansatz nutzt Luftbilder, die mithilfe des 4k-Kamerasystems des DLR an Bord eines Hubschraubers simultan zur Testfahrt eines mit GNSS-Empfängern
bestückten Fahrzeugs aufgenommen werden.

Authors: Fäßler Lisa , Dittrich Ingo , Lutz Theo , Ziegler Jonas , Frindik Roland , Koch Günter
Published: June 2024

Der zunehmende Güterverkehr auf Stadtstraßen belastet die Anwohner, Verkehrsteilnehmer und die Umwelt. Die Nutzung von Straßenbahnen zur Bewältigung des regionalen Güterverkehrs kann dazu beitragen, eine Entlastung zu erzielen, indem eine bereits vorhandene Schieneninfrastruktur genutzt wird. In dieser Studie wird untersucht, welche Anforderungen an die Transportdienstleitung einer Güterstraßenbahn bestehen und wie diese in das logistische Konzept integriert werden können. Die Forschungsfrage wird mit einem qualitativen Studiendesign in Form einer multiplen Fallstudie beantwortet.

Dieser Artikel führt die wichtigsten Erkenntnisse zweier Projekte aus Wien und Berlin zusammen und gibt konkrete Empfehlungen, wie Mobilitätsmaßnahmen in Wohnquartieren zum gewünschten Erfolg führen können.
GGG-Klassen für Fahrzeuge
Authors: Otto-Zimmermann Konrad , Kahnt Sophie Elise , Milbradt Jori , Sommer Carsten
Published: June 2024

Werden alle Personen-Individualfahrzeuge nach Merkmalen von Größe, Gewicht und Geschwindigkeit (GGG) erfasst und nach objektiven Schwellenwerten in sieben Klassen eingeteilt, so können die S-Klassen
(XXS, XS, S) als Feinmobilität bezeichnet werden. Die GGG-Klassen sind geeignet, stadträumlich relevanten Planungen, Infrastrukturbemessungen und Verkehrsregelungen zugrunde gelegt zu werden. Dies
erlaubt eine sachgerechte Differenzierung, wo das gegenwärtig eine Bemessungsfahrzeug „PKW“ zur längerfristigen Festschreibung von flächen- und kostenintensiven Verkehrsanlagen führt.

Published: June 2024

Die Länder Afrikas sind derzeit für nur 3,8 % der weltweiten CO2-Emissionen verantwortlich. Mit wachsenden Volkswirtschaften und Bevölkerungen nehmen die Emissionen auf dem Kontinent rapide zu – vor
allem im Verkehrssektor, der bereits eine wichtige Emissionsquelle ist. Urbanisierung, hohe Investitionsbedarfe in Infrastruktur und eine steigende Mobilitätsnachfrage bedingen Wachstum und Wandel des Sektors. Globale Trends der Elektrifizierung, der Nutzung erneuerbarer Energien und der digitalen Innovation bieten zahlreiche Möglichkeiten für einen Sprung zu nachhaltigem Verkehr auf dem Kontinent.
Towards Vision Zero
Authors: de Ponte Müller Fabian , Munoz Diaz Estefania , Sand Stephan , Böker Clarissa , Merk Lukas
Published: June 2024

Almost half of the casualties on European roads can be accounted to the group of the so-called Vulnerable Road Users (VRUs). The introduction of V2X Communication makes it possible to extend the awareness horizon of automated and autonomous vehicles, in order to avoid accidents with VRUs. In this paper we learn how V2X communication will protect VRUs, what requirements have to be met, what the key performance metrics are and how different communication and localization technologies perform. The Vision Zero goal is to reduce the road traffic casualties including VRUs to zero.
The Gender Mobility Data Gap
Authors: Weinmann Viviane
Published: June 2024

Die UN-Ziele für nachhaltige Entwicklung widmen der Gleichstellung der Geschlechter und ihrer Bedeutung für eine verbesserte Teilhabe, Sicherheit und Chancen für Frauen und Mädchen eine besondere
Aufmerksamkeit. Im Verkehrssektor ist die Verwirklichung der Geschlechtergerechtigkeit eine Frage der Zugänglichkeit und Sicherheit für Frauen und Mädchen bei der Nutzung von Mobilitätsangeboten. Eine
Herausforderung im Vorantreiben der Geschlechtergerechtigkeit besteht darin, die geschlechtsspezifischen Datenlücken zu schließen. In vielen Fällen sind die Daten und Informationen zu allen Aspekten des täglichen Lebens, einschließlich Mobilität, nicht nach dem Geschlecht aufgeschlüsselt oder basieren, wie Caroline Criado-Perez schreibt, auf einer „standardmäßigen männlichen“ Erfahrung.
Wie sich die Autobahn digitalisieren will
Authors: Jung Stefan
Published: June 2024

Effiziente Transportwege sind wichtiger denn je: Fast 3,7 Milliarden Tonnen Güter werden jedes Jahr über deutsche Straßen transportiert. Obwohl es mit Flug- und Schienenverkehr viele Alternativen gibt, ist die Autobahn als Transportweg beliebt wie nie, denn kaum ein anderes Land verfügt über ein längeres und besser ausgebautes Straßennetz. Um die Infrastruktur in bestem Zustand zu halten und ihre Leistungsfähigkeit weiter zu steigern, soll die 2018 gegründete Autobahn GmbH des Bundes den Betrieb in allen 16 Bundesländern zentral verwalten, mit den verfügbaren Ressourcen besser planen und Bau- und Instandhaltungsprojekte effizienter umsetzen. Dazu wurden GIS-basierte Technologien etabliert, mit deren Hilfe sowohl der Zustand der Autobahnen als auch der Bestand der Bäume nun dauerhaft mithilfe visueller Dashboards überblickt und verwaltet werden kann.

Erfolgreiche Zukunft des Schienenverkehrs in Deutschland?
Authors: Stoll Fabian , Kogel Bastian
Published: June 2024

Die Zukunft des Schienenverkehrs in Deutschland wird wesentlich von der Verkehrspolitik des Bundes beeinflusst. Aufgrund vielfältiger ungelöster Herausforderungen besteht ein dringender politischer Handlungsbedarf. Ohne eine weitere Aufstockung des Verkehrsetats wird eine Finanzierung der für den Deutschlandtakt erforderlichen Infrastrukturvorhaben mittel- und langfristig nicht möglich sein. Zudem bedarf es einer massiven Beschleunigung der Umsetzungszeiträume. In kurzfristiger Hinsicht ist es bedeutsam, den multiplen Überlastungserscheinungen des Schienennetzes zu begegnen und verschärfte Rentabilitätsprobleme des Eisenbahnbetriebs abzuwenden.

Lieferantenkartelle erhöhen Infrastrukturkosten
Authors: Wallimann Hannes , Sticher Silvio
Published: June 2024

Die Verkehrsinfrastruktur ist ein Grundpfeiler jeder Volkswirtschaft. Sie ist aber auch kostenintensiv, was akzentuiert wird durch deren Anfälligkeit für Kartelle. Maschinelle
Lerntechniken ermöglichen es, Datensätze mit Preisgeboten von Verkehrsinfrastruktur-Bauunternehmen nach Mustern zu untersuchen. Im Rahmen einer aktuellen Untersuchung hat die Hochschule Luzern Modelle anhand von Kartell-Daten trainiert. Dies ermöglichte es, bei 1.206 Infrastruktur-Beschaffungen der Schweizerischen Bundesbahnen (SBB) zwischen 2015 und 2021 nach Indizien für Kartelle zu suchen. Vorliegender Artikel zeigt, wie dies im Detail funktioniert, was dabei herauskam und wo die Grenzen
der Interpretierbarkeit solcher „Screenings“ liegen.
