Published: August 2023

AbstractThe archaeological excavation of two abandoned prehispanic agricultural terraces (Infiernillo and Tocotoccasa) in the Chicha-Soras Valley (Apurimac) in southern-central Peru revealed the presence of palaeosols. The palaeosols represent soil that developed following construction of agricultural terraces during the Middle Horizon. The soil profiles at the current surface developed following reconstruction of the terraces during the Late Intermediate Period. Phytolith analysis revealed an unexpected presence of Arecaceae (palm family) and Marantaceae (arrowroot family) in both terraces, which has been attributed to local cultivation and/or transportation and use of soil, dung, plant material or implements (made of Arecaceae) on the terrace surfaces. Pollen analysis of a nearby wetland (Ayapampa) did not provide evidence for Arecaceae or Marantaceae. Both phytolith and pollen analysis of the terraces and wetland (respectively) indicated thatZea mayswas cultivated locally during the Middle Horizon and Late Intermediate Period, although phytoliths of maize are absent from the wetland record during the Middle Horizon. The presence of Solanaceae and Chenopodiaceae/Amaranthaceae pollen in the wetland may be indicative of cultivation of further important taxa during the Middle Horizon and Late Intermediate Period, which continued into the Late Horizon together withZea mays.

Published: August 2023

Abstract
Purpose
Autologous breast reconstruction improves patient satisfaction and quality of life after mastectomy. In Germany, free flap surgery and implant-based reconstruction is usually separate between reconstructive surgery and gynecology. Cooperation between the specialist disciplines and implementation of microsurgery into breast surgeon training could enhance surgical treatment for breast cancer patients. This evaluation is intended to demonstrate the learning progress within a microsurgical training program and the complication rate in relation to microsurgical experience.

Methods
At the breast cancer center at Klinikum rechts der Isar, TU Munich, a three-stage training program for autologous breast reconstruction and microsurgery for gynecological breast surgeons was developed. Between 2019 and 2022, 74 women received autologous free flap breast reconstruction by a consistent team consisting of a gynecological surgeon in training and an expert microsurgeon. Peri- and postoperative data were collected to analyze the feasibility and safety of a microsurgical training in gynecology.

Results
Within the training, operative steps of free autologous breast reconstruction were increasingly taken over by the gynecological surgeon in training. The analysis showed a decrease in operating times with consistently low complication rates during the training.

Conclusion
This study demonstrated that a training in free autologous breast reconstruction for gynecological surgeons is safely feasible through close cooperation between gynecological and reconstructive surgery.

Abstract
Objective
To identify CT features and establish a diagnostic model for distinguishing non-ampullary duodenal neuroendocrine neoplasms (dNENs) from non-ampullary duodenal gastrointestinal stromal tumors (dGISTs) and to analyze overall survival outcomes of all dNENs patients.

Materials and methods
This retrospective study included 98 patients with pathologically confirmed dNENs (n = 44) and dGISTs (n = 54). Clinical data and CT characteristics were collected. Univariate analyses and binary logistic regression analyses were performed to identify independent factors and establish a diagnostic model between non-ampullary dNENs (n = 22) and dGISTs (n = 54). The ROC curve was created to determine diagnostic ability. Cox proportional hazards models were created and Kaplan–Meier survival analyses were performed for survival analysis of dNENs (n = 44).

Results
Three CT features were identified as independent predictors of non-ampullary dNENs, including intraluminal growth pattern (OR 0.450; 95% CI 0.206–0.983), absence of intratumoral vessels (OR 0.207; 95% CI 0.053–0.807) and unenhanced lesion > 40.76 HU (OR 5.720; 95% CI 1.575–20.774). The AUC was 0.866 (95% CI 0.765–0.968), with a sensitivity of 90.91% (95% CI 70.8–98.9%), specificity of 77.78% (95% CI 64.4–88.0%), and total accuracy rate of 81.58%. Lymph node metastases (HR: 21.60), obstructive biliary and/or pancreatic duct dilation (HR: 5.82) and portal lesion enhancement ≤ 99.79 HU (HR: 3.02) were independent prognostic factors related to poor outcomes.

Conclusion
We established a diagnostic model to differentiate non-ampullary dNENs from dGISTs. Besides, we found that imaging features on enhanced CT can predict OS of patients with dNENs.

We show homotopy-universality, that is, for every semi-algebraic set S there is a polygon P such that V(P) is homotopy equivalent to S. Furthermore, for various concrete topological spaces T, we describe instances I of the art gallery problem such that V(I) is homeomorphic to T.
A social-aware video sharing solution using demand prediction of epidemic-based propagation in wireless networks
Authors: Jia Shijie , Cui Yan , Su Xiaoyan , Liang Zongzheng 
Published: August 2023

AbstractThe video services that account for the majority of global network traffic consume significant amounts of electricity and network resources to meet the large-scale demand of users. Variations in user interest and social influence lead to high maintenance costs for achieving a dynamic balance between supply and demand, which negatively impacts the sustainable development of video services. In this paper, we propose a social-aware video-sharing solution using demand prediction of epidemic-based propagation in wireless networks (SDPEP). SDPEP constructs a video propagation model based on user “pull” and “push” sharing behaviors and designs an estimation method for calculating the probability of video fetching by investigating user interests and social relationships. SDPEP uses the probability of video fetching to calculate the basic reproduction number during epidemic-based video propagation, predicting user demand during the propagation process. To ensure efficient caching with low-cost adjustments to video distribution, SDPEP employs a caching-based adjustment strategy for distributing videos while maintaining dynamic balance between supply and demand. Extensive testing shows that SDPEP outperforms other state-of-the-art solutions.

Published: August 2023

AbstractIn aqueduct stenosis, pressure difference below and above level of obstruction leads to bulging of third ventricular floor (TVF) and lamina terminalis (LT). Endoscopic third ventriculocisternostomy (ETV) is the standard treatment in these patients. We tried to assess success of ETV depending on those two radiological changes in aqueduct stenosis. We implemented “Heidelberg ETV score” retrospectively to assess the state of TVF as well as LT in same manner in midsagittal MR image. Every patient had a preoperative, direct, 3-months and one-year postoperative score from -2 to + 2. We correlated the scores to clinical course to decide whether the score is reliable in defining success of ETV. Between 2017–2021, 67 (mean age 25.6 ± 23.9y) patients treated with ETV were included. Success rate of primary and Re-ETVs was 91% over 46.8 ± 19.0 months. A marked shift of score to the left after surgery in success group was noticed through the distribution of score immediate postoperative, 3-months later; 70.2% showed (+ 2) before surgery, 38.9% scored (0) after surgery and 50.9% showed further score drop to (-1) 3 months later, p < 0.001. In cases of failure, there was initial decrease after surgery followed by increase with ETV-failure (mean time to failure: 7.2 ± 5.7 months) in 100%. Significant difference was noticed in Heidelberg score at postoperative 1-year- and failure-MRI follow-up between two groups, p < 0.001. Heidelberg score describes anatomical changes in third ventricle after ETV and can serve in assessment of MR images to define success of the procedure in patients with aqueduct stenosis.
Emergence, Continuity, and Scientific Realism
Authors: Dieks Dennis 
Published: August 2023

AbstractScientific realism postulates that science aims for truth in both the domains of the observable and the unobservable, and is capable of achieving this aim, at least approximately. From the realist perspective our current scientific theories are on the right path to their aim, encapsulating a significant degree of theoretical truth. A key argument supporting this viewpoint is the continuity observed between successive scientific theories, interpreted as the preservation of truth. However, we contend that this continuity argument is problematic in significant cases. Features of older theoretical schemes frequently do not persist in subsequent theories but emerge as limiting cases with restricted applicability domains and fine-grained structures that differ from what the older theories deemed possible. The alterations accompanying theory replacement are often more drastic than what is assumed by realist intuition, justifying skepticism about continuity serving as an indicator of theoretical truth preservation. We propose an argument wherein continuity is instead viewed as a consequence of empirical success preservation.
The role of aftercare in plant translocation
Authors: Corli Anna , Rocchetti Giulia Albani , Orsenigo Simone , Possley Jennifer , Abeli Thomas 
Published: August 2023

AbstractPlant translocation can increase the chances of long-term survival of threatened plant species; nevertheless, can be costly and challenging, with unknowns in the pre- and post-release phases, limiting success. Methodological advances have been made in the pre-release phase but long-term monitoring and post-release site management (i.e., “aftercare”) are not always applied and almost neglected in the literature despite being frequently effective for identifying and mitigating unexpected threats (e.g., interspecific competition, herbivory) to outplant survival.Aiming to fill this gap, we reviewed published and gray literature on 296 translocations to shed light on the importance of aftercare on translocation outcome. We identified the most common aftercare techniques, then we performed a meta-analysis on a subset of studies that were specifically designed to test the effect of aftercare against a control (i.e., no aftercare).The most common aftercare techniques were competition reduction, water irrigation and plant protection. Aftercare significantly increased the percentage of survival of plants when herbivory reduction and other understorey species were enhanced. Aftercare reported also a positive trend toward improved qualitative outcome when plants were protected or competition was mitigated. Nevertheless, more evidence is needed on the importance and effectiveness of aftercare techniques.Long-term monitoring and post-release site management should be the post-translocation standard in plant translocations when ethical and possible, with plant protection, competition limitation and water irrigation being applied when needed to reduce transplant mortality. To provide statistically supported data on the effect of aftercare on translocation outcome, aftercare should be tested against a control when feasible.

Published: August 2023

AbstractFunctional magnetic resonance imaging can provide detailed maps of how sensory space is mapped in the human brain. Here, we use a novel 16 stimulator setup (a 4 × 4 grid) to measure two-dimensional sensory maps of between and within-digit (D2–D4) space using high spatial-resolution (1.25 mm isotropic) imaging at 7 Tesla together with population receptive field (pRF) mapping in 10 participants. Using a 2D Gaussian pRF model, we capture maps of the coverage of digits D2–D5 across Brodmann areas and estimate pRF size and shape. In addition, we compare results to previous studies that used fewer stimulators by constraining pRF models to a 1D Gaussian Between Digit or 1D Gaussian Within Digit model. We show that pRFs across somatosensory areas tend to have a strong preference to cover the within-digit axis. We show an increase in pRF size moving from D2–D5. We quantify pRF shapes in Brodmann area (BA) 3b, 3a, 1, 2 and show differences in pRF size in Brodmann areas 3a-2, with larger estimates for BA2. Generally, the 2D Gaussian pRF model better represents pRF coverage maps generated by our data, which itself is produced from a 2D stimulation grid.
Profane Pregnant Bodies Versus Sacred Organizational Systems: Exploring Pregnancy Discrimination at Work (R2)
Authors: Gatrell Caroline , Ladge Jamie J. , Powell Gary N. 
Published: August 2023

AbstractThis paper explores how pregnancy discrimination at work is perceived by both employers and pregnant employees. Using a public, qualitative dataset collected by the UK Equality and Human Rights Commission that offers perspectives from both employers and pregnant employees, we explore the unfair and unethical treatment of pregnant employees at work. Our findings show how pregnant workers are expected to conform with workplace systems that are treated as sacred. We suggest that employer valorization of the mythical figure of ‘ideal worker’ disadvantages pregnant workers. We observe how, even if this contravenes maternity protection laws, some employers self-justify discrimination against pregnant employees who they perceive to have transgressed ‘appropriate’ workplace behaviors as ethical and reasonable. To illuminate and conceptualize the notion of transgression, our analysis has led us to the ideas of philosopher Georges Bataille, specifically his reflections on how individuals who ‘transgress’ social norms are treated as taboo, as well as his metaphorical descriptions of people and practices as either sacred or profane. We theorize that pregnant workers who are treated as profane should be reclassified as sacred, opening up this idea for debate so as to disrupt long-standing patterns of discrimination.

Published: August 2023

AbstractThis study attempts to understand the impact of electronic Word of Mouth (eWOM) on corporate financial performance during the COVID-19 pandemic. A supervised machine learning is used to determine the investors’ sentiment of a news story (eWOM) towards a given company from a long position (buying) investors perspective. Ordinary Least Square (OLS) and dynamic quantile regression are used to test the role of eWOM on financial performance. Results reveal no significant relationship between eWOM and the firm’s financial performance. Similarly, we do not find any evidence of an association between eWOM and corporate performance at different quantiles of financial performance. The findings contribute to the existing literature on eWOM and its impact on the financial performance during specific circumstances or financial crises. This study offers insights to researchers, policymakers, regulators, financial report users, investors, employees, clients, and society.
Rating ESG key performance indicators in the airline industry
Authors: Caraveo Gomez Llanos Alan Francisco , Vijaya Annas , Wicaksono Hendro 
Published: August 2023

AbstractThe environmental, social, and governance (ESG) integration finds itself in a transition with rapid developments worldwide, given that the pandemic incentivized companies and investors to focus on other social and governance measures such as ESG ratings. However, the divergence of ratings from the ESG and a lack of transparency lead the companies to report voluntary indicators without standardization. This study aimed to identify the ESG criteria and the most suitable set of key performance indicators (KPIs) in the airline industry after the impact of COVID-19. Furthermore, the second objective was to determine the appropriate weights and ranking of the identified criteria. The multi-criteria decision-making analytical hierarchical process was applied for this purpose. Additionally, the use of intuitionistic variables delivers a comprehensive model for rating the airlines according to their ESG performance. The most relevant criteria found in the study were critical risk management, greenhouse gas emissions, and systemic risk management. Regarding the KPIs, the top-3 weights were the number of flight accidents, jet fuel consumed and sustainable aviation used, and the number of digital transformation initiatives.
Who Asks Questions and Who Benefits from Answers: Understanding Institutions in Terms of Social Epistemic Dependencies
Authors: Werner Konrad 
Published: August 2023

AbstractThe paper develops the idea that institutions are enablers. However, they do not only enable individuals and collectives to achieve their goals; first and foremost, they enable individuals and collectives to have a goal, to select and recognize certain possible states of affairs as targets of action, and as a result, to have a demand – especially a demand for further institutions. I make the case that properly functioning institutions are dedicated to making these states of affairs epistemically acquaintable. What I will stress in particular is that acquaintance is first realized in the form of questions, which are linguistic expressions of acts of problematization. However, I will discuss less what an individual subject questions, but rather what the social dynamic of questioning is. This dynamic will be conceptualized in terms of epistemic dependence, and it will be singled out as the dynamic that gives rise to institutions.
Population genetic structure of intensively exploited pikeperch (Sander lucioperca) in Lake Balaton (Hungary)

Published: August 2023

AbstractPikeperch (Sander lucioperca Linnaeus, 1758) is a wide-ranged percid predator fish characterised by a great ecological value in the Eurasian freshwater and brackish ecosystems. It is also one of the most famous fish species of Lake Balaton (Hungary), where a unique (genetically separated) pikeperch stock lives. However, until now, no detailed information was available about the pikeperch population genetic structure in Lake Balaton. In the present study, the population genetic structure of the pikeperch assemblages in the lake was revealed by using microsatellite markers. Commercial fishery and angler catch data going back more than 100 years verified that the pikeperch has always been a key element of Lake Balaton’s fish stock utilization. Results of genetic data analyses showed that the pikeperch in the Lake Balaton forms a metapopulation system, in which only the westward stocks show certain separation. Moreover, it seems that the exploitation and mass fish kills that happened in the 1960s and 1970s may have had only a slight impact on the population genetic structure of Balaton pikeperch stocks. The information about genetic features and utilization changes of pikeperch stocks can help to develop area-specific management plans and ensure the long-term survival of this carnivore fish species characteristic of Lake Balaton.
Distinguishing laboratory characteristics in giant cell arteritis: a real-world retrospective cohort study

Published: August 2023

Abstract
Background
Untreated Giant Cell Arteritis (GCA) has the potential to cause serious complications such as vision loss. Appropriate initial assessment by General Practitioners, early treatment and specialist referral are therefore essential in reducing morbidity. However, lack of awareness around the range of presentations can lead to a delay in diagnosis.

Objective
We aim to evaluate the discriminative diagnostic performance of laboratory characteristics associated with GCA in our population over a period of 18 months.

Discussion
This is a real-world retrospective review of patients referred to ophthalmology services with concern for GCA. The pre-test probability of a patient referred with suspected GCA was 13.9% to have GCA, highlighting the need for specialist referrals to continue. White Cell Count (p = 0.01), Platelet Count (p = 0.02), Erythrocyte sedimentation rate (p = 0.004) and C-reactive protein (p = 0.002) were significantly different between GCA and non-GCA cases. Moreover, this study demonstrates that absolute neutrophil count (p = 0.02) can be a useful parameter in initial investigations for GCA.
