Abstract
Background
Among all types of superficial gastrointestinal (GI) neoplasms, colorectal lesions are recognized as one of the most difficult locations to operate, due to the limited operation space, physiological bends, poor visualization of the submucosal dissection plane sheltered by colorectal crinkle wall, and the thin intestinal mucosa layer which is easy to perforation. The purpose of this prospective study is to evaluate the feasibility, efficacy, and safety of a novel endoscopic traction technique in assisting the endoscopic submucosal dissection (ESD) procedure in colorectal lesions.

Method
A total of 117 patients with colonic lesions who underwent endoscopic treatment were enrolled between August 2020 and January 2021 at the endoscopic center of Beijing Chao-yang Hospital of Capital Medical University. Based on whether traction device was used during the operation, 60 and 57 patients were assigned to the conventional ESD group and clips and rubber band triangle traction-assisted ESD group (CRT-ESD, in which three clips and a rubber band were used to form an elastic triangular traction device), respectively. The total procedure time (TPT), submucosal dissection time (SDT), submucosal dissection speed (SDS), and rate of adverse events of the two groups were analyzed.

Results
After excluding patients who did not undergo treatment (conventional ESD, 1; CRT-ESD, 4), 112 patients were included in the study (conventional ESD, 59; CRT-ESD, 53). The baseline characteristics of the patients were well balanced between the two groups. The TPT (58.71 ± 26.22 min vs 33.58 ± 9.88 min, p < 0.001) and SDT (49.24 ± 23.75 min vs 26.34 ± 8.75 min, p < 0.001) were significantly different between the conventional ESD group and CRT-ESD group. The CRT-ESD group had significantly higher SDS than that of the traditional ESD group (0.54 ± 0.42 cm2/min vs 0.89 ± 0.40 cm2/min, p < 0.001). There were 4 (6.8%) cases of perforation in the traditional ESD group, and no perforation occurred in traction-assisted ESD.

Conclusions
Compared with traditional ESD, CRT-ESD with clip and rubber band is both safer and more effective in the treatment of colorectal lesions.

AbstractHaiti’s groundwater resources are poorly understood and scarcely researched, despite their importance as the principal source for water supply. The knowledge gap and its role of inhibiting informed relief, recovery and investments in development are described, along with an update on progress towards the UN Sustainable Development Goals. This essay leads a topical collection of seven articles that advance hydrogeological knowledge of Haiti. Additional data, research and monitoring are identified as urgently needed for the nation’s sustainable development.
Families of Polytopes with Rational Linear Precision in Higher Dimensions

Published: August 2022

AbstractIn this article, we introduce a new family of lattice polytopes with rational linear precision. For this purpose, we define a new class of discrete statistical models that we call multinomial staged tree models. We prove that these models have rational maximum likelihood estimators (MLE) and give a criterion for these models to be log-linear. Our main result is then obtained by applying Garcia-Puente and Sottile’s theorem that establishes a correspondence between polytopes with rational linear precision and log-linear models with rational MLE. Throughout this article, we also study the interplay between the primitive collections of the normal fan of a polytope with rational linear precision and the shape of the Horn matrix of its corresponding statistical model. Finally, we investigate lattice polytopes arising from toric multinomial staged tree models, in terms of the combinatorics of their tree representations.
Ecology, genetics and distribution of Punctoribates zachvatkini, an oribatid mite so far overlooked in Germany

Published: August 2022

AbstractPunctoribatesis one of few genera in Poronota (Acari: Oribatida) containing species with porose areas and species with saccules, the two types of the octotaxic system. These porose organs are the main difference between two morphologically similar species,P. punctumwith porose areas andP. zachvatkiniwith saccules. As the octotaxic system can vary within species, species separation solely based on this trait might be insufficient. To assess the species status ofP. zachvatkini, we investigated additional differences fromP. punctumby comparing habitat preferences of the two species regarding nature reserves and agricultural landscapes during a field study in the German Eifel region, and by examiningPunctoribatesmaterial from four large German natural history museums. We also performed scanning electron microscopy (SEM) and a genetic analysis using the D3 marker of the nuclear 28S rDNA gene. In the field study,P. zachvatkinihad higher densities in the nature reserves andP. punctumin the agricultural landscapes. Evaluation of the museum material revealedP. punctumoccurred more regularly in disturbed sites such as urban, agricultural and post-mining areas compared toP. zachvatkini. Pairwise distances of the 28S D3 genetic marker as well as an additional base pair inP. zachvatkinifurther support the separation of the two species, and SEM investigations revealed new details regarding the punctulation ofP. zachvatkini. The review of the museum material showed thatP. zachvatkinialready occurred in Germany in 1967 and has a wider distribution than previously known.
Outpatient Therapists’ Perspectives on Working With Persons Who Are Sexually Interested in Minors
Authors: Schmidt Alexander F. , Niehaus Susanna 
Published: August 2022

AbstractMinor-attracted persons (MAPs; i.e., people who are sexually interested in children and adolescents below the age threshold of legal consent for sexual activity) exhibit high psychological distress but report difficulties finding therapeutic help and are reluctant to start treatment due to fears of therapist stigmatization. This research sought to elucidate the link between outpatient therapists’ stigmatizing attitudes toward non-offending versus offending MAPs and therapists’ willingness to treat MAPs as well as how stigmatization was related to treatment-relevant aspects such as perceived MAP treatment needs, treatment barriers, and specific MAP treatment skills. Results from a brief, anonymous online survey conducted among N = 427 Swiss outpatient therapists working in the primary healthcare system are reported. Although therapists were less stigmatizing than the general public, considerable individual differences in the stigmatization of non-offending MAPs emerged. Stigmatizing attitudes toward non-offending MAPs and a perceived lack of specific treatment competences were negatively related to therapists’ willingness to treat MAPs. A network analysis revealed direct links between subjectively perceived MAP treatment competence and treatment willingness and between treatment willingness and social distance attitudes. Other stigmatizing attitudes were only indirectly linked to treatment willingness through preferred social distance. It is a paradox that therapists believe that MAPs should greatly benefit from secondary prevention but many are unwilling to provide therapy (45% in case of non-offending MAPs vs. 63% in case of offending MAPs) or do not feel competent to provide MAPs with professional help (47% with and 88% of therapists without previous MAP treatment experience). Implications for increasing therapists’ treatment willingness are discussed.

Published: August 2022

AbstractThe present study developed a brief version of the Hungarian Why Sex? questionnaire (Meskó et al., 2022). The study was in part based on previously reported data obtained from several samples (N = 6193; 1976 men, 4217 women). Using Mokken Scaling Procedure, Item Response Model and redundancy analysis indicated that retaining three summary scales comprising five items each was the optimal solution for the brief version. The validity of the brief scale was tested with the Sexual System Functioning Scale (SSFS), the Experiences in Close Relationships Scale–Short Form (ECR-S) and, the Hungarian version of the Attachment Style Questionnaire (ASQ-H; n = 297, 127 men, 170 women). In addition, correlations between the long and brief versions of YSEX? with sociosexual orientation (SOI-R) and the five-factor personality construct (BFI-S) were compared (n = 1024, 578 women, 446 men). The results suggest that the three summary scales of the Hungarian 15-item Form of the Why Sex Questionnaire (YSEX?-15H) provide reliable and valid measures of the previously affirmed three broad sexual motives (Personal Goal Attainment, Relational Reasons, Sex as Coping). The Relational Reasons summary scale was associated with secure emotional and sexual attachment. The Personal Goal Attainment and Sex as Coping summary scales showed coherent patterns of associations with the emotional and sexual aspects of secondary attachment strategies (over- and under-functioning). The YSEX?-15H offers both researchers and practitioners a concise and useful instrument for the assessment of sexual motivation.
Tough Clinical Decisions: Experiences of Polish Physicians

Published: August 2022

AbstractThe paper reports results of the very first survey-based study on the prevalence, frequency and nature of ethical or other non-medical difficulties faced by Polish physicians in their everyday clinical practice. The study involved 521 physicians of various medical specialties, practicing mainly in inpatient healthcare. The study showed that the majority of Polish physicians encounter ethical and other non-medical difficulties in making clinical decisions. However, they confront such difficulties less frequently than their foreign peers. Moreover, Polish doctors indicate different circumstances as a source of the experienced problems. The difficulties most often reported relate to (i) patients (or their proxies) requests for medically non-indicated interventions; (ii) problems with communication with patients (or their proxies) due to the patients’ negative attitude, unwillingness to cooperate, or aggression; and (iii) various difficulties with obtaining informed consent. Polish physicians report difficulties associated with disagreements among care givers or scarcity of resources less frequently than doctors from other countries. The study’s findings provide support for the thesis that a significant portion of Polish physicians still follow a traditional, paternalistic, and hierarchical model of healthcare practice. Instead of promoting patient’s empowerment, engagement, and rights, they often consider these ideas as a threat to physicians’ professional authority and autonomy. The study leads to the conclusion that due to insufficient training in medical ethics, communication skills, and medical law, many Polish physicians lack the knowledge and competence necessary to adequately respond to challenges posed by modern healthcare practice.

AbstractAdditive manufacturing (AM) is projected to require 60,000 jobs in the UK by 2025, but there are a series of barriers to the industrial application. One of the most problematic is non-comprehensive knowledge in design for AM (DfAM). This study aims to test the effect of two undergraduate DfAM teaching approaches. A visual and audial approach (design lecture) and a kinaesthetic, problem-based learning (PBL) approach (manufacturing laboratory) were compared against technical and participant perspective criteria to assess the learning, engagement, and self-efficacy of the students. The participants were set a DfAM challenge; to redesign a bracket. The technical merits of the designs were evaluated after teaching through a design lecture alone or after a design lecture and manufacturing-laboratory. The participant’s perspective was evaluated at the end of the study. The groups who undertook both the design lecture and manufacturing laboratory showed a mean technical mark of 100% for criteria (C) 13 (“Parts have been consolidated into one part”), 91.7% for C14 (“The bracket is hollowed where possible”) and 100% for C16 (“Manufacture was successful”). These technical marks demonstrate a statistically significant increase over those of the groups who undertook the design lecture alone. The participant evaluation reinforced this result; the manufacturing laboratory was chosen more frequently in answer to questions on applicability (Q13 = 83%), preparedness (Q15 = 83%), and gaining confidence in DfAM (Q31 = 74%). This study demonstrates the importance of PBL in DfAM, both to increase technical aptitude of the student (creativity and manufacturing) and their perspective on their own learning and self-efficacy.

AbstractFor solving numerically fractional differential equations, we have to take into account a rising flow of works as (Dehestani et al. in Appl Math Comput 336:433–453, 2018, https://doi.org/10.1016/j.amc.2018.05.017, Rahimkhani et al. Appl Math Model 40:8087–8107, 2016, https://doi.org/10.1016/j.apm.2016.04.026) that show the advantage of using the transformation $$x \rightarrow x^\alpha $$

. In this paper, we aim to explain this transformation, and using the acquired knowledge, we are also discussing a method that is able to improve the accuracy of the numerical results for the delay fractional equations. We conclude the paper with two numerical examples to illustrate the analysis of this paper.
Impact of Tropical Cyclone Avoidance on Fishing Vessel Activity over Coastal China Based on Automatic Identification System Data during 2013–2018

Published: August 2022

AbstractTropical cyclones (TCs) may cause severe impacts on the activities of coastal fishing vessels. Due to the unavailability or unacceptability of detailed Automatic Identification System (AIS) data that are capable of differentiating fishing activity from navigation, as well as the lack of detailed models and observation data of TC winds, few studies have provided quantitative and reliable assessment of the impacts of TCs on fishing activities. In this study, we modeled snapshots for the TC winds of 52 TCs over the Northwest Pacific (NWP) basin from 2013 to 2018, as well as daily fishing hours and daily hours of presence (hereafter “vessel hours”) of fishing vessels. Based on these data, the spatiotemporal pattern of fishing vessel activity over offshore China was first analyzed and mapped. Then, a TC wind hazard index and absolute and relative impact indices were proposed to assess the impact of the 52 TCs on fishing and vessel hours. Their relationship was then fitted with the cumulative distribution function (CDF) of the log-normal distribution. The results show that in the 2013−2018 period, the most active fishing areas were located in the South China Sea. In each instance, an increase was first observed in the initial several years; then a decrease followed in the yearly total fishing hours per vessel in the remaining years. The relative impact index was significantly correlated to the TC wind hazard index proposed in this study. Based on the quantitative relationship between the specified TC hazard index and the impact indices, it is possible to implement a pre-cyclone rapid loss assessment due to TC avoidance in the future.

AbstractIn response to the basic policy of green and low-carbon circular development to solve resource, environmental and ecological problems, gypsum is considered to be a filling material for mine backfilling. To explore the potential risks of gypsum to the groundwater environment due to the backfilling of abandoned mines, a sequential batch leaching experiment was carried out in this paper, which used three types of industrial waste gypsum, namely, phosphorus gypsum (PG), titanium gypsum (TG) and flue gas desulfurization gypsum (FGDG). COMSOL Multiphysics 5.4 software was used to simulate and solve the migration process of the leached metal elements in the mine floor when these three gypsum types were used as filling materials to observe the concentration distributions and diffusion distances of the metal elements from these three gypsum types in the mine floor. The results show that (1) during repeated contact of the three types of industrial waste gypsum with the leaching medium, the pH levels changed, and the changes in pH affected the leaching patterns for the heavy metal elements in the gypsum. (2) Based on the concentrations of the metal elements that were leached from the three types of gypsum, it can be determined that these three types of gypsum are not classified as hazardous solid wastes, but they cannot be ruled out with regard to their risk to the groundwater environment when they are used as mine filling materials. (3) When the three types of gypsum are used as filling materials, the concentration distributions of the metal elements and their migration distances all exhibit significant changes over time. The concentration distributions, diffusion rates and migration distances of the metal elements from the different gypsum types are affected by their initial concentrations in the leachate. The maximum migration distances of Zn in the floor from the PG, FGDG and TG are 8.2, 8.1 and 7.5 m, respectively.
Angebote politischer Erwachsenenbildung vor und nach dem „Corona-Schock“
Authors: Scheidig Falk 
Published: August 2022

ZusammenfassungIm Zusammenhang mit der Corona-Pandemie wird einerseits ein langfristiger Angebotsrückgang in der Erwachsenenbildung befürchtet, andererseits wird diskutiert, ob die als „Schock“ beschriebene Unterbrechung des Präsenzbetriebs mit einem Digitalisierungsschub einherging. Der Beitrag knüpft hieran an und fokussiert Verschiebungen im Verhältnis von Präsenz- und Online-Veranstaltungen im Bereich der politischen Erwachsenenbildung auf Basis einer Analyse der Programme von 30 Volkshochschulen. Verglichen werden der letzte Programmzeitraum vor der Pandemie und der Programmzeitraum ab Herbst 2021, in dem Präsenzveranstaltungen wieder weitgehend möglich waren. Die Ergebnisse zeigen einen Rückgang bei Präsenzveranstaltungen und eine deutliche Zunahme von Online-Veranstaltungen, darunter vor allem überregional angebotene Kurzzeitveranstaltungen auf Basis von Einrichtungskooperationen. Zwischen den 30 Volkshochschulen lassen sich jedoch große Unterschiede konstatieren. Die Ergebnisse, ihre Übertragbarkeit auf andere Anbieter und Inhaltsbereiche der Erwachsenenbildung sowie die methodischen Herausforderungen einer Programmanalyse im Horizont zunehmender Digitalisierung werden diskutiert.

Published: August 2022

AbstractThis investigation aimed to improve the hatchery seed production strategy in terms of chronologies of embryonic and larval development as well as hatching, growth and survival rates, and rearing water quality of green tiger prawn, Penaeus semisulcatus by the integration effects of different water temperatures (23 °C, 26 °C, 29 °C, 32 °C) and probiotic as water additives. The best and shortest chronologies of embryonic development stages were in favor of 32 °C with probiotic. The best hatching rate was in favor of 29 °C with probiotics. The fastest larval development and greatest larval growth as total length until PL1 stage was promoted by 32 °C with probiotic but the best survival rate was recorded at 26 °C with probiotic followed by 29 °C with probiotic treatment. During larval development, the lowest value of NH4–N was recorded under the effect of 26 °C and probiotic. Therefore, probiotics as water additives at 29 and 32 °C water temperatures have a beneficial impact on the hatchery seed production strategy and quality of P. semisulcatus. Our findings could apply to rearing larvae in shrimp hatchery to decrease the chronology of embryonic and larval development, while increase the hatching rate, growth performance, and survival rates as well as improving the water quality.
Using Dominated Solutions at Edges to the Diversity and the Uniformity of Non-dominated Solution Distributions in NSGA-II
Authors: Sato Yuji , Sato Mikiko 
Published: August 2022

AbstractThis paper proposes a method for improving the diversity of the Pareto front and the uniformity of non-dominated solution distributions in a fast elitist non-dominated sorting genetic algorithm (NSGA-II), which is an evolutionary multi-objective optimization algorithm. Conventional NSGA-II has excellent convergence to the Pareto front, but it has been reported that for some test cases, it does not produce a more diverse solution distribution than the strength Pareto evolutionary algorithm 2 (SPEA2). In addition, selection using the crowding distance may cause a bias in the selected solution distribution. To avoid this problem, we propose a method that archives dominated solutions that may be effective in improving diversity in the conventional search process when used for genetic operations, and mates these archived solutions with non-dominated solutions at the edge of rank 1 for each objective function. We experimentally compare this approach with the conventional method on the typical ZDT suite of multi-objective test problems and a two-objective constrained knapsack problem. By evaluating the performance based on Pareto front diagrams, the number of non-dominated solutions, the maximum spread and hypervolume values, we show that the proposed method is effective at improving the diversity at both ends of the Pareto optimal front and the solution distribution.
