Der Tankrabatt: Haben die Mineralölkonzerne die Steuersenkung an die Kunden weitergegeben?
Authors: Fuest Clemens , Neumeier Florian , Stöhlker Daniel 
Published: July 2022

Zusammenfassung
Im vorliegenden Beitrag untersuchen Clemens Fuest, Florian Neumeier und Daniel Stöhlker die Auswirkungen des Tankrabatts auf die Preise für Superbenzin und Diesel an deutschen Tankstellen. Die Preiseffekte werden auf Basis eines Differenz-in-Differenzen-Ansatzes geschätzt, in dem Frankreich als Kontrollgruppe dient. Den Ergebnissen zufolge wurde der Tankrabatt im Fall von Diesel zu 100 Prozent an die Autofahrerinnen und Autofahrer weitergegeben. Im Fall von Superbenzin beträgt die Weitergabe 85 Prozent. Dass die Preise dennoch nicht dauerhaft gesunken sind, hat andere als steuerliche Gründe. Aus diesen Ergebnissen folgt aus Sicht der Autoren jedoch nicht, dass der Tankrabatt wirtschaftspolitisch eine sinnvolle Antwort auf die steigenden Energiepreise ist. Er setze das falsche Preissignal und komme vorwiegend Haushalten zugute, die überdurchschnittlich hohe Einkommen erzielen. Außerdem erhöhe er die Nachfrage nach Kraftstoffen und stehe damit im Konflikt zu ökologischen Zielen.

Abstract
This study focusses on the synthesis of polyaniline (PANI) and polyaniline base adsorbent utilizing Citrus limon leaves (CL) powder. The polyaniline base adsorbent with C. limon was synthesized using the same process as polyaniline synthesis, but with the addition of leaves powder. PANI and PANI based adsorbent with C. limon leaves powder (PANI/CL) were characterized by Fourier Transform Infra-Red (FTIR), UV-Visible spectroscopy and Scanning Electron Microscopy (SEM). This synthesized material was employed for the removal of congo red (CR) dye from industrial wastewater. Furthermore, the Langmuir, Temkin and Freundlich isotherms were also applied to evaluate experimental results. PANI is an efficient adsorbent for CR removal with 71.9 mg/g, while PANI/CL is an efficient adsorbent with 80 mg/g removal of dye according to a comparison of maximal adsorption capabilities. The data concludes that the prepared adsorbents could possibly be employed for the removal of toxic dyes from industrial effluents at large scale and ultimately could help in improving the environment.

Abstract
Perri, T, Reid, M, Murphy, A, Howle, K, and Duffield, R. Determining stroke and movement profiles in competitive tennis match-play from wearable sensor accelerometry. J Strength Cond Res 37(6): 1271–1276, 2023—This study determined stroke and movement accelerometry metrics from a wearable sensor and compared between court surface (grass vs. hard) and match outcome (win vs. loss) during competitive tennis match-play. Eight junior high-performance tennis players wore a trunk-mounted global positioning system, with in-built accelerometer, magnetometer, and gyroscope during singles matches on hard and grass courts. The manufacturer software calculated accelerometer-derived total player load (tPL). A prototype algorithm classified forehands, backhands, serves, and “other” strokes, thereby calculating stroke PL (sPL) from individual strokes. Movement PL (mPL) was calculated as the difference between tPL and sPL, with all metrics reported as absolute and relative (min−1, %, and ·stroke). Analysis of accelerometer load and stroke count metrics was performed through a two-way (surface [grass vs. hard] × match outcome [win vs. loss]) analysis of variance (p < 0.05) and effect sizes (Cohen's d). No interaction effects for surface and match outcome existed for absolute tPL, mPL, and sPL (p > 0.05). Increased mPL% featured on grass courts, whereas sPL% was increased on hard courts (p = 0.04, d = 1.18[0.31–2.02]). Elevated sPL·min−1 existed on hard courts (p = 0.04, d = 1.19[0.32–2.04]), but no differences in tPL·min−1 and mPL·min−1 were evident for surface or outcome (p > 0.05). Relative forehand sPL (FH-sPL·min−1) was higher on hard courts (p = 0.03, d = 1.18[0.31–2.02]) alongside higher forehand counts (p = 0.01, d = 1.29[0.40–2.14]). Hitting demands are heightened on hard courts from increased sPL and counts. Conversely, increased mPL% on grass courts likely reflects the specific movement demands from point-play. Physical preparation strategies during training blocks can be tailored toward movement or hitting loads to suit competitive surfaces.

Abstract
Edwards, T, Weakley, J, Woods, CT, Breed, R, Benson, AC, Suchomel, TJ, and Banyard, HG. Comparison of countermovement jump and squat jump performance between 627 state and non-state representative junior Australian football players. J Strength Cond Res 37(3): 641–645, 2023—This cross-sectional study investigated differences in lower-body power of state and nonstate representative junior Australian football (AF) players through countermovement jump (CMJ) and squat jump (SJ) performance. A total of 627 players performed the CMJ and SJ at the end of the preseason phase over a 2-week period, with each player grouped according to their age (under 18 [U18] or under 16 [U16]), and highest competition level played (state representation and nonstate representation). One-way multivariate analysis of variance (MANOVA), follow up ANOVA's, and Cohen's d effect sizes were used to identify significant main effects and between-group differences. Statistical significance was set at α < 0.05. Significant small-to-moderate effect size differences were observed between competition level, with state U18 and U16 players recording greater CMJ and SJ height, and peak power (PP), compared with their nonstate representative peers, respectively. Similarly, significant small-to-moderate effect size differences existed between age groups, with nonstate U18 players recording greater CMJ and SJ height and PP than nonstate U16 counterparts. However, state U18 and state U16 only differed in CMJ PP. No differences were found between competition level or age groups for the difference between CMJ and SJ jump height (CMJSJdiff). Together, these findings suggest that state and nonstate representative junior AFs may have a similar ability to use the stretch-shortening cycle, despite state representative players jumping higher in the CMJ and SJ.

Abstract
Lambrianides, Y, Epro, G, Smith, K, Mileva, K, James, D, and Karamanidis, K. Impact of different mechanical and metabolic stimuli on the temporal dynamics of muscle strength adaptation. J Strength Cond Res 36(11): 3246–3255, 2022—A fundamental task in exercise physiology is to determine and ultimately improve the adaptations that take place in the human body, an integrated network of various physiological systems, for example, muscle, tendon, and bone. Investigating the temporal dynamics (time course) of adaptations in these diverse systems may help us gain new knowledge about the functioning of the neuromotor system in healthy and pathological conditions. The aim of this review was to explore the temporal dynamics of muscular strength adaptations in studies implementing a resistance training intervention. In addition, we categorized these studies under mechanical or metabolic stimuli to identify whether certain stimuli cause faster muscle strength gains. Searches were performed using PubMed and Google Scholar databases. The review comprised 708 subjects from 57 training groups within 40 studies that met the inclusion criteria. The results revealed that the mean time point of first significant increase in muscle strength of all studies was 4.3 weeks, and the corresponding increase was on average about 17%. A plateau in muscle strength increase (∼25%) was found to occur between weeks 8 and 12. Categorization into stimuli groups revealed that performing training in a hypoxic environment is likely to produce a leftward shift (∼25% increase at ∼2.8 weeks) in the dose-response relationship compared with blood flow restriction and supplementation. However, stimuli that cause faster muscle strength gains may also induce imbalanced adaptation between the muscle and the surrounding biological structures, potentially triggering a degradation in some parts of the network (i.e., leading to an increased risk of injury).

Relaciones de poder y jerarquía en un ordenamiento productivo local de una ciudad brasileña
Authors: Mello José André Villas Boas , Pinto Bruno Guimarães Jorge 
Published: July 2022

This research aims to identify how power and hierarchy relations emerge in a production system that influence the authenticity dimensions of a local productive arrangement. The research is exploratory and had data collected from interviews with local managers from organizations of local size and influence. The data collected from the interviews allowed qualifying the studied productive system, as well as advancing on Storper and Harrison’s (1991) proposals, taking as original the study of a local productive arrangement (LPA) of a medium and peripheral city in Brazil. It is concluded that the qualitative aspects favorable to the LPA have the “core-ring structure with coordinating signature” as a very present characteristic that influences the authenticity dimensions of the arrangement. Given this perspective, it is also highlighted that the territorial dimension and rootedness are well defined, as the region is perceived as the best option for the purchase and installation of automotive businesses. Tacit knowledge, innovation, and governance are underdeveloped. As a central result, one can point to a possible stronger variable to what Lastres and Cassiolato (2004) call the authenticity of local productive arrangements, that is, the relations of power and hierarchy existing in the production system can constitute a variable that interferes in the other dimensions and confers the authenticity of a local productive arrangement.

Published: July 2022

El propósito de este artículo es explicar la asociación entre el desarrollo de habilidades de lectura del español como idioma materno con el método de enseñanza y las características académicas y sociodemográficas del estudiantado de primero primaria de San José Pinula en Guatemala. Con un diseño cuasiexperimental y una muestra de 104 estudiantes, que se distribuyeron en grupos control y experimental. Se aplicó en 2016 la Evaluación de Lectura para Grados Iniciales (ELGI[1]) desarrollada por el Ministerio de Educación de Guatemala. La investigación se desarrolló en dos etapas, en la primera se logró la caracterización de los métodos implementados por el equipo docente de primero de primaria para enseñar a leer y escribir; en la segunda se implementó la intervención metodológica con materiales didácticos, capacitación metodológica y acompañamiento al equipo de docentes durante todo el curso lectivo: experimental (fonológico comprensivo) y el control (silábico). Los resultados del modelo de regresión lineal múltiple demostraron que la implementación del método se asoció significativamente con el desarrollo de las habilidades de: conciencia fonológica, principio alfabético, decodificación y automatización, en tanto que no hubo diferencias en fluidez entre el grupo experimental y el de control. Asimismo, el método contribuyó a explicar el desarrollo de estas habilidades en conjunto con las características académicas y sociodemográficas del estudiantado. Para superar la brecha en aprendizajes luego de la pandemia, se recomienda fortalecer la formación de docentes en métodos más efectivos, como el fonológico comprensivo para la enseñanza de la lectura mediante el diseño de guías didácticas y cuadernos de trabajo para el estudiantado, que promuevan actividades sistemáticas para el aprendizaje de estas habilidades, sumado a una estrategia pedagógica intensiva para reducir el retraso lector inicial y una política de incentivos para lograr que las mejores personas docentes sean asignadas y permanezcan en primero primaria.

Authors: Li Bao Qiong , Li Ze Ying , Li Xin Kang , Tan Lin Fan 
Published: July 2022

AbstractA new method for the analysis of four target flavonoids in two kinds of citrus samples by ultra-high performance supercritical fluid chromatography (UHPSFC) method was developed. Main variables affecting the UHPSFC separation were optimized, and under the optimized conditions the four target compounds (tangeretin, nobiletin, hesperetin and naringenin) can be separated within 10 min. The UHPSFC method allowed the determination of the four target compounds in the diluted stock solutions with limit of detection (LOD) ranging from 1.08 to 2.28 μg mL−1, and limit of quantification (LOQ) ranging from 1.45 to 4.52 μg mL−1, respectively. The coefficients of determination (R2) of the calibration curves were higher than 0.9950. The recoveries of the four target compounds at three different concentrations were in the range of 82.4–117.6%. The validation results demonstrated that the proposed method is simple, accurate, time-saving and environment friendly, and it is applicable to a variety of complex samples such as medicine-food dual purpose herbs and functional foods.

Introduction: In recent decades, there has been a growing increase in the diagnosis of patients with inborn errors of the immune system, formerly known as primary immunodeficiency disorders (PIDs). Timely diagnosis remains a challenge due to low clinical suspicion and poor education on the subject. It is estimated that between 70% and 90% of these pathologies remain underdiagnosed in our environment.
Objective: The objective of this study is to characterize the demographic and clinical presentation of pediatric group patients with inborn errors of the immune system in a Colombian tertiary hospital.
Methods: Retrospective descriptive study of 306 patients with a diagnosis of innate errors of the immune system who consulted the PID clinic between 2011 and 2018 in a high-complexity institution in Cali, Colombia.
Results: Three-hundred and six patients were included. The median age was 4 years (IQR 2.3–7.7 years), and 59.5% of the patients were male. According to the International Union of Immunological Societies Expert Committee for Primary Immunodeficiency classification for inborn errors of the immune system, the most common group was antibody deficiency in 74.8% (n˂229), especially in the age group between 1 and 5 years. The least frequent in our population was complement deficiency. Of the warning signs stipulated for these pathologies, the most frequent were the (1) need for intravenous antibiotics (32%), (2) difficulty growing (15.7%), (3) four or more episodes of ear infection (10.8%), and (4) abscesses in organs or cutaneous abscesses (12.7%). No patient reported two or more episodes of pneumonia or sinusitis, and only 5.8% of the patients received a bone marrow transplant.
Conclusions: Innate errors of the immune system require an early diagnosis with follow-up from an early age to ensure adequate management and follow-up in order to reduce morbidity and mortality. It is imperative to sensitize the medical population about the existence of these pathologies so that early intervention can be carried out, which improves the quality of life of patients and their families.
Conditioned medium from the bone marrow mesenchymal stem cells modulates immune response via signal transduction and activator of transcription 6 signaling pathway in an allergic rhinitis mouse model

Published: July 2022

Background: Allergic rhinitis (AR) is a common immune disease of the nasal mucosa characterized with immunoglobulin E (IgE)-mediated allergic inflammation after exposure to allergens in susceptible population. Previous reports have demonstrated that the bone marrow mesenchymal stem cells (BMSCs) could reduce allergic inflammation. However, there is little knowledge about whether the culture supernatant of BMSCs (conditioned medium, CM) has similar anti- inflammatory potential in treating AR.
Objective: The study aimed to evaluate the immunoregulatory effects of conditioned medium derived from BMSCs (BMSC-CM) on allergic inflammation in an AR mouse model.
Material and Methods: The AR murine model was induced by repeated sensitization and challenges with ovalbumin (OVA). Subsequently the allergic symptoms of AR mice, cytokine levels, the histopathological features of the nasal mucosa and T helper 1 (Th1) : T helper 2 (Th2) cells ratio were evaluated.
Results: Treatment with BMSC-CM was found as effective as BMSCs in reducing allergic symptoms and inhibiting eosinophilic infiltration in the nasal mucosa. After BMSC-CM or BMSCs administration, the OVA-specific IgE and interleukin 4 levels in serum decreased and interferon gamma level increased compared with AR mice treated with uncultured fresh medium. Flow cytometry analysis revealed a decrease in Th1:Th2 cells ratio after OVA-sensitization and the ratio was reversed by BMSC-CM and BMSCs treatments. Furthermore, the data revealed that BMSC-CM suppressed the production of signal transduction and activator of transcription 6 (STAT6) at messenger RNA and protein levels in the nasal mucosa.
Conclusion: BMSC-CM could ameliorate allergic inflammation and regulate the balance of Th cells, and the underlying mechanism was closely related to STAT6 signaling pathway. The immunoregulatory effects of BMSCs could be achieved through paracrine function, and nasal dripping of BMSC-CM might be a novel approach for the treatment of AR.

AbstractObjective. The semiology of temporo‐basal epilepsy has rarely been analysed in the literature. In this paper, we report three patients with proven basal temporal epilepsy with somatomotor or somatosensory facial ictal semiology, highly suggestive of insulo‐opercular onset.Methods. The three patients had a temporobasal lesion and their drugresistant epilepsy was cured with resection of the lesion (follow‐up duration: 7–17 years). We reviewed the medical charts, non‐invasive EEG data as well as the stereoelectroencephalography (SEEG) performed in two patients. Quantitative analysis of ictal fast gamma activity was performed for one patient.Results. Early ictal features were orofacial, either somatomotor in two patients or ipsilateral somatosensory in one. The three patients had prior sensations compatible with a temporal lobe onset. Interictal and ictal EEG pointed to the temporal lobe. The propagation of the discharge to the insula and operculum before the occurrence of facial features was seen on SEEG. Facial features occurred 7–20 seconds after electrical onset. Quantitative analysis of six seizures in one patient confirmed the visual analysis, showing statistically significant fast gamma activity originating from basal areas and then propagating to insuloopercular regions after a few seconds.Significance. We report three cases of lesional temporo‐basal epilepsy responsible for orofacial semiology related to propagation of insulo‐opercular ictal discharge. In MRI‐negative patients with facial manifestations, this origin should be suspected when EEG is suggestive. These observations may contribute to our understanding of brain networks.
