Authors: Albrecht Martin , Dittrich-Wesbuer Andrea 
Published: June 2021

Zusammenfassung Steigende Mobilität ist ein Megatrend unserer Zeit. Dies betrifft auch das Wohnen – häufige Umzüge und Wohnen auf Zeit werden für immer mehr Menschen zum Alltag. In diesem Trend liegt das multilokale Wohnen. Doch wie viele multilokal Lebende gibt es und was lässt sich über diese Gruppe aussagen? Diesen Fragen widmet sich Kapitel 3. Der Beitrag fasst im ersten Teil die Erkenntnisse aus Forschungsarbeiten sowie nutzbare Zahlen der amtlichen Statistik zusammen. Im zweiten Teil wird die Datenlage im Landkreis Diepholz im Detail betrachtet. Vorgestellt wird ein speziell entwickeltes Tool, das eine erste Annäherung an die mögliche quantitative Entwicklung von multilokalen Arrangements auf der regionalen Ebene ermöglicht. Insgesamt kontrastiert der Beitrag, dass auf allen Ebenen erhebliche Kenntnisdefizite und Datenlücken bestehen und plädiert für eine differenzierte, quantitative und qualitative Aspekte umfassende, Beschäftigung mit dieser zukunftsweisenden Thematik.

Abstract
Purpose
Patients suffering from aggressive systemic peripheral lymphoma with primary central nervous system involvement (PCL) are a rare and sparsely investigated population. Recommended treatment regimens include a combination of intrathecal and systemic chemotherapy as well as whole brain radiotherapy while offering relatively poor survival.

Methods
We conducted a single-center retrospective study that analyzed safety and outcome of 4 + 4 cycles Rituximab (R)-CHOP and R-high-dose Methotrexate (HD-MTX) for newly diagnosed, transplant-eligible patients (“Ping-Pong”), followed by Cytarabine (AraC)/Thiotepa (TT), BCNU/TT, and autologous hematologic stem cell transplantation (aHSCT). We retrospectively analyzed a set of 16 patients with high–intermediate or high-risk IPI status.

Results
Overall response rate to Ping-Pong was 100% measured by CT/MRI, including 93.75% complete remissions after BCNU/TT followed by PBSCT. One patient failed to qualify for high-dose chemotherapy due to progression when receiving Cytarabine/TT. All patients experienced grade III adverse events, 3 of them a grade IV adverse event. Estimated progression-free survival is 93.75% after a 4.8-year follow-up currently.

Conclusion
Our study suggests high effectivity of R-CHOP with mid-cycle MTX with aHSCT consolidation towards acceptable OS results in this challenging patient population.
Bounds on the Lattice Point Enumerator via Slices and Projections
Authors: Freyer Ansgar , Henk Martin 
Published: June 2021

AbstractGardner et al. posed the problem to find a discrete analogue of Meyer’s inequality bounding from below the volume of a convex body by the geometric mean of the volumes of its slices with the coordinate hyperplanes. Motivated by this problem, for which we provide a first general bound, we study in a more general context the question of bounding the number of lattice points of a convex body in terms of slices, as well as projections.

Published: June 2021

Abstract
Background
To identify the association between diabetes mellitus (DM) and the risk of chemotherapy-induced peripheral neuropathy (CIPN) through a systematic review and meta-analysis.

Methods
An electronic literature search was conducted in PubMed, Embase, Web of Science, the Wanfang database, the VIP Journals database (CQVIP), the China National Knowledge Infrastructure (CNKI) database, and the China Biology Medicine database (Sinomed) between January 2010 and January 2021. Articles were included if they investigated CIPN and DM. Stata 15.1 was used to analyze the data.

Results
We examined 8923 cancer patients from 25 studies comprising 9 cohort studies and 16 case–control studies. Meta-analysis showed that there was a statistically significant positive correlation between DM and CIPN (odds ratio [OR] = 1.60, 95% confidence interval [CI] = 1.38–1.85, P < 0.001). Egger’s test (P = 0.824) showed no evidence of publication bias. The positive associations did not significant differ by study type, study quality, evaluation instrument, and type of antineoplastic drug. Omission of any single study had little effect on the combined risk estimate. Little evidence of heterogeneity was observed.

Conclusion
This meta-analysis provides evidence of a significant positive association between DM and risk of CIPN. Furthermore, a more detailed evaluation is warranted for cancer patients with diabetes when they are treated with antineoplastic drugs that have the potential to cause peripheral neuropathy.

Defining the niche for niche construction: evolutionary and ecological niches
Authors: Trappes Rose 
Published: June 2021

AbstractNiche construction theory (NCT) aims to transform and unite evolutionary biology and ecology. Much of the debate about NCT has focused on construction. Less attention has been accorded to the niche: what is it, exactly, that organisms are constructing? In this paper I compare and contrast the definition of the niche used in NCT with ecological niche definitions. NCT’s concept of the evolutionary niche is defined as the sum of selection pressures affecting a population. So defined, the evolutionary niche is narrower than the ecological niche. Moreover, when contrasted with a more restricted ecological niche concept, it has a slightly different extension. I point out three kinds of cases in which the evolutionary niche does not coincide with realized ecological niches: extreme habitat degradation, commensalism, and non-limiting or super-abundant resources. These conceptual differences affect the role of NCT in unifying ecology and evolutionary biology.
Social Accountability, Ethics, and the Occupy Wall Street Protests
Authors: Neu Dean , Saxton Gregory D. , Rahaman Abu S. 
Published: June 2021

AbstractThis study examines the 3.5 m+ English-language original tweets that occurred during the 2011 Occupy Wall Street protests. Starting from previous research, we analyze how character terms such as “the banker,” “politician,” “the teaparty,” “GOP,” and “the corporation,” as well as concept terms such as “ethics,” “fairness,” “morals,” “justice,” and “democracy” were used by individual participants to respond to the Occupy Wall Street events. These character and concept terms not only allowed individuals to take an ethical stance but also accumulated into a citizen’s narrative about social accountability. The analysis illustrates how the centrality of the different concepts and characters in the conversation changed over time as well as how the concepts ethics, morals, fairness, justice, and democracy participated within the conversation, helping to amplify the ethical attributes of different characters. These findings contribute to our understanding of how demands for social accountability are articulated and change over time.
Structural, electrical and electrochemical studies of ionic liquid-based polymer gel electrolyte using magnesium salt for supercapacitor application
Authors: Gupta Ashish , Jain Amrita , Tripathi S. K. 
Published: June 2021

AbstractIn the present studies, the effect of ionic liquid 1-Ethyl-2,3-dimethylimidazoliumtetrafluoroborate (EDiMIM)(BF4) on ionic conductivity of gel polymer electrolyte using poly(vinylidene fluoride-co-hexafluoropropylene) [PVdF(HFP)] and magnesium perchlorate [Mg(ClO4)2] as salt was investigated. The maximum room temperature ionic conductivity for the optimized system was found to be of the order of 8.4 × 10–3 S cm−1. The optimized composition reflects Vogel-Tammann-Fulcher (VTF) behavior in the temperature range of 25 °C to 100 °C. The X-ray diffraction, Fourier transform infrared spectroscopy and scanning electron microscopy studies confirm the uniform blending of ionic liquid, polymer, and salts along with the enhanced amorphous nature of the optimized system. Dielectric and modulus spectra studies provide the information of electrode polarization as well as dipole relaxation properties of polymeric materials. The optimized electrolyte system possesses a sufficiently large electrochemical window of the order of 6.0 V with stainless steel electrodes.

Abstract
Background
High-grade gliomas are among the most aggressive central nervous system primary tumors, with a high risk of recurrence and a poor prognosis. Re-operation, re-irradiation, chemotherapy are options in this setting. No-best therapy has been established. Bevacizumab was approved on the basis of two Phase 2 trials that evaluated its efficacy in patients with recurrent glioblastoma.

Materials and methods
We have retrospectively review data of patients with high-grade glioma treated at our institution that undergone radiological or histological progression after at least one systemic treatment for recurrent disease. Bevacizumab was administered alone or in combination with chemotherapy until disease progression or unacceptable toxicity. Bevacizumab regimen was analyzed to assess PFS and OS. Histological, molecular and clinical features of the entire cohort were collected.

Results
We reviewed data from 92 patients, treated from April 2009 to November 2019, with histologically confirmed diagnosis of high-grade gliomas and recurrent disease. A PFS of 55.2%, 22.9% and 9.6% was observed at 6, 12 and 24 months, respectively. Performance status, age at diagnosis (< 65 or > 65 ys.) and use of corticosteroids during bevacizumab therapy were strongly associated with PFS. The OS was 74.9% at 6 months, 31.7% at 12 months, 10.1% at 24 months. In our cohort, 51.1% were long-term responders (PFS > 6 months). Globally, bevacizumab treatment was well tolerated.

Conclusion
Our analysis confirms the efficacy of bevacizumab in recurrent high-grade glioma patients with an acceptable toxicity profile, in keeping with its known safety in the literature.
Evolutionary Computation in Social Propagation over Complex Networks: A Survey
Authors: Zhao Tian-Fang , Chen Wei-Neng , Ma Xin-Xin , Wu Xiao-Kun 
Published: June 2021

AbstractSocial propagation denotes the spread phenomena directly correlated to the human world and society, which includes but is not limited to the diffusion of human epidemics, human-made malicious viruses, fake news, social innovation, viral marketing, etc. Simulation and optimization are two major themes in social propagation, where network-based simulation helps to analyze and understand the social contagion, and problem-oriented optimization is devoted to contain or improve the infection results. Though there have been many models and optimization techniques, the matter of concern is that the increasing complexity and scales of propagation processes continuously refresh the former conclusions. Recently, evolutionary computation (EC) shows its potential in alleviating the concerns by introducing an evolving and developing perspective. With this insight, this paper intends to develop a comprehensive view of how EC takes effect in social propagation. Taxonomy is provided for classifying the propagation problems, and the applications of EC in solving these problems are reviewed. Furthermore, some open issues of social propagation and the potential applications of EC are discussed. This paper contributes to recognizing the problems in application-oriented EC design and paves the way for the development of evolving propagation dynamics.
Understanding the challenges to investigating and prosecuting organ trafficking: a comparative analysis of two cases
Authors: Ambagtsheer Frederike 
Published: June 2021

AbstractThe human organ trade is proliferating globally. However, far fewer cases have been prosecuted than would be expected based on estimates of the crime. Research exploring the challenges to investigating and prosecuting organ trafficking cases is practically non-existent. Also no studies exist that explain these challenges utilizing a criminal justice framework. This article aims to explain the legal, institutional and environmental factors that affected the investigation and prosecution of two organ trafficking cases: theNetcare case,exposed in South Africa and theMedicuscase, exposed in Kosovo. It analyzes these factors through a comparative, mixed-method design, utilizing a theoretical criminal justice framework. Both cases constituted globally operating criminal networks involving brokers and transplant professionals that colluded in organizing illegal transplants. Both cases contained human trafficking elements, however only the Medicus case was prosecuted as a human trafficking case. Legal uncertainty, a lack of institutional readiness and cross-border collaboration issues hampered investigation and prosecution of the Netcare case. The Medicus case also reported problems during cross-border collaboration, as well as a corrupt environment and institutional barriers, which impeded a successful case outcome. Recommendations to improve enforcement of organ trafficking include improving identification of suspicious transplant activity, strengthening cross-border collaboration and enhancing whistleblower protection laws.
Disparities in Students’ Propensity to Consent to Learning Analytics
Authors: Li Warren , Sun Kaiwen , Schaub Florian , Brooks Christopher 
Published: June 2021

AbstractUse of university students’ educational data for learning analytics has spurred a debate about whether and how to provide students with agency regarding data collection and use. A concern is that students opting out of learning analytics may skew predictive models, in particular if certain student populations disproportionately opt out and biases are unintentionally introduced into predictive models. We investigated university students’ propensity to consent to learning analytics through an email prompt, and collected respondents’ perceived benefits and privacy concerns regarding learning analytics in a subsequent online survey. In particular, we studied whether and why students’ consent propensity differs among student subpopulations bysending our email prompt to a sample of 4,000 students at our institution stratified by ethnicity and gender. 272 students interacted with the email, of which 119 also completed the survey. We identified that institutional trust, concerns with the amount of data collection versus perceived benefits, and comfort with instructors’ data use for learning engagement were key determinants in students’ decision to participate in learning analytics. We find that students identifying ethnically as Black were significantly less likely to respond and self-reported lower levels of institutional trust. Female students reported concerns with data collection but were also more comfortable with use of their data by instructors for learning engagement purposes. Students’ comments corroborate these findings and suggest that agency alone is insufficient; institutional leaders and instructors also play a large role in alleviating the issue of bias.
Water film area and dust removal efficiency of string grilles: a theoretical analysis
Authors: Guo Hua , Wang Haiqiao , Chen Shiqiang , Wu Zhirong 
Published: June 2021

AbstractBased on multiphase flow theory and capillary mechanics, the dimensionless bond number expression of the influence of string grille wire spacing on droplet spreading is derived. Taking a liquid film formed by spreading droplets based on Kelvin correlation, the Young–Laplace equation, and the Hagen–Poiseuille law, an equation for calculating the thickness and height of the liquid film is established with temperature, relative humidity and molar volume of liquid phase as independent variables. According to the theory of string grille filtration and dust removal, a dust removal efficiency calculation model covering the wet string grille wire group is constructed based on the liquid film thickness, height, wire diameter, water film area, and vortex shedding frequency. Finally, a theoretical analysis of the influence of water film area on the efficiency of wet string grille dust removal is carried out based on the spray pressure and the ratio of string grille wire distance to wire diameter. It is found that the effect of spray pressure on water film area and dust removal efficiency is more significant than the string grille wire distance diameter ratio. Moreover, the optimized combination of wet string grille wire distance diameter ratio 0.84, wind speed 3 m/s and spray pressure 0.8 MPa is found, which could provide an important reference for engineering applications.
System identification of wind effects on multirotor aircraft
Authors: Wei Peng , Lin Xinfan , Kong Zhaodan 
Published: June 2021

AbstractMultirotor airplanes are widely used in many outdoor applications, e.g., agriculture, transportation, and public safety, where winds might be strong and prevalent. However, the effects of wind on multirotor aircraft are still not fully understood yet. The objective of this paper is to investigate and model wind effects on a real hovering octocopter. The wind is directly measured and considered as one of the inputs to the bare-airframe model. Then a series of models, each corresponding to a different wind condition, are identified from real flight data through a system identification approach. The time-domain validation results show that an average of 15% error reduction can be achieved by considering wind effects, captured by a wind correction term. The identified models will play an important role for the future development of model-based controllers for outdoor multirotor aircraft.

Published: June 2021

AbstractThe current study was carried out to examine the spatial and temporal variations of physicochemical water quality parameters of Lake Bunyonyi. The observations were made on the surface water of Lake Bunyonyi for 1 year to determine the water quality. The basic 12 variables used to determine the quality of water were measured monthly at nine stations. Water temperature, dissolved oxygen (DO), turbidity, electric conductivity (EC), pH and Secchi depth (SD) were measured in the field, while parameters like total nitrogen (TN), total phosphorus (TP), nitrite-nitrogen (NO2-N), nitrate-nitrogen (NO3-N), soluble reactive phosphorus (SRP) were determined following APHA 2017 standard guidelines for physicochemical analysis. Taking into account standard guidelines for drinking water by the Uganda National Bureau of Standards (UNBS) and the World Health Organization (WHO), the water quality index (WQI) was used to determine the water quality. Temperature, DO, pH, turbidity and EC did not differ significantly among the study stations (p > 0.05) but showed significant temporal variations among the study months (p < 0.05). Likewise, TN, TP, NO2-N, NO3-N and SRP did not differ significantly among the study stations (p > 0.05) but showed significant temporal variations among the study months (p < 0.05). The WQI values ranged from 28.36 to 49 across and from 28.2 to 56.2 between study months with an overall mean value of 36.9. The measured water quality variables did not exceed the UNBS and WHO standards for drinking water in all months and at all stations. According to these values, the water quality of Lake Bunyonyi generally belongs to the ‘good’ class in terms of drinking water quality based on the WQI classification. The study findings are fundamentally important for policy makers in setting guidelines for effective lake management.
