Sekundärrohstoffbasierte Versatzprodukte im Bergbau – Mineralwolleabfälle für den ressourcenschonenden Versatz
Authors: Sattler Theresa , Galler Robert , Vollprecht Daniel 
Published: November 2021

ZusammenfassungVersatz wird im Bergbau aus sicherheitstechnischen, umweltrelevanten, bergtechnischen und wirtschaftlichen Gründen durchgeführt. Durch den Einsatz von Versatzprodukten kann die Gebirgsfestigkeit sowie die Stabilität erhöht werden. Somit können beispielsweise einsturzgefährdete Hohlräume aus aufgelassenen Bergbauen gesichert und Bergschäden, wie z. B. Tagbrüche, vermieden werden. Um ein bergbaufremdes Material einzusetzen, müssen rechtliche Vorgaben erfüllt werden, die Notwendigkeit der Versatztätigkeit muss begründet werden und das eingesetzte Versatzprodukt hat mechanische und chemische Eigenschaften zu erfüllen. Der Versatz mit sekundärrohstoffbasiertem Material kann die geforderten Funktionen erfüllen, wenn eine geeignete Versatzrezeptur entwickelt wurde. Im Fall von Mineralwolleabfall kann dieser, nach dem Einbringen in eine Bindemittelmatrix, als Bestandteil eines Versatzprodukts eingesetzt werden. Da Mineralwolleabfälle aktuell in Österreich deponiert werden, ab dem 01.01.2027 jedoch ein Verbot für die Deponierung von Mineralwolleabfälle durch den Gesetzgeber beschlossen wurde, stellt die „sonstige Verwertung“ im Bergversatz eine sinnvolle Alternative dar.
A machine learning-based price state prediction model for agricultural commodities using external factors
Authors: Oktoviany Prilly , Knobloch Robert , Korn Ralf 
Published: November 2021

AbstractIn recent times of noticeable climate change the consideration of external factors, such as weather and economic key figures, becomes even more crucial for a proper valuation of derivatives written on agricultural commodities. The occurrence of remarkable price changes as a result of severe changes in these factors motivates the introduction of different price states, each describing different dynamics of the price process. In order to include external factors we propose a two-step hybrid model based on machine learning methods for clustering and classification. First, we assign price states to historical prices using K-means clustering. These price states are also assigned to the corresponding data of external factors. Second, predictions of future price states are then obtained from short-term predictions of the external factors by means of either K-nearest neighbors or random forest classification. We apply our model to real corn futures data and generate price scenarios via a Monte Carlo simulation, which we compare to Sørensen (J Futures Mark 22(5):393–426, 2002). Thereby we obtain a better approximation of the real futures prices by the simulated futures prices regarding the error measures MAE, RMSE and MAPE. From a practical point of view, these simulations can be used to support the assessment of price risks in risk management systems or as decision support regarding trading strategies under different price states.
Der Zinssatz ist kein Preis
Authors: Hellwig Martin 
Published: November 2021

ZusammenfassungDie Interpretation des Zinssatzes als Preis ist problematisch. Im Gegensatz zum Preis ist der Zinssatz kein Austauschverhältnis. Modelle, in denen der Zinssatz mit einem Preis für die Nutzung von Kapital identifiziert werden kann, sind sehr speziell. In allgemeineren Modellen sind Zinssatz und Mietpreise für Kapital verschieden. Die dogmengeschichtliche Entwicklung hinter dieser Diskussion deutet auf eine apologetische Funktion der Interpretation des Zinssatzes als Mietpreis für Kapital. Im Hintergrund steht die Frage, in welchen Einheiten Zinssatz und „Kapital“ gemessen werden.
The waste ban in China: what happened next? Assessing the impact of new policies on the waste management sector in China

Published: November 2021

AbstractThe 2017 ban on the waste import and new policies for the waste management sector in mainland China had wide-spread impact. After decades of poor environmental and public health impacts from the sector, a study is needed which focuses on policies updates and waste management. This provides a direction for the survival of local waste management industries and consider similarities with the ban promulgated in China on the restriction of waste import from other countries. We review the waste management situation in China before national legislation prevented the import of waste, highlight the status of landfill mining in China, and review the dynamics of domestic policies before and after the promulgation of the ban in China. The impact of the COVID19 pandemic on the waste management system is starting to emerge, providing both challenges and opportunities for the sector in China. We see the impact of the ban on the range of imported waste and domestically generated materials. The ban results in price increases for domestic recycling that forces companies to introduce more formal recycling processes and to drive the consumption behaviours to more reasonable and environmentally friendly options. The driver in China is to reduce pollution in the environment and improve health, but a negative impact has been from increased landfill mining which has impeded the original aim of the waste ban and requires further technological development. The dynamic of domestic policies in China shows higher level of activity of updates and revisions or introduction of new policies from 2015 onwards and the concept of ‘zero waste cities’ brings new hope for improvement of the Chinese waste management system. The pandemic also suggests an important step to establish sustainable management systems despite evidence of increased “fly-tipping”. The rebound of the waste ban may have stimulated in the short term negative impacts on local environments both in China and internationally.
The Italian Version of Smartphone Addiction Inventory (SPAI-I) for Adolescents: Confirmatory Factor Analysis and Relation with Self-Control and Internalized-Externalized Symptoms
Authors: Bassi Giulia , Lis Adriana , Marci Tatiana , Salcuni Silvia 
Published: November 2021

AbstractThe increased smartphone use in adolescence has led clinicians and researchers to carry out in-depth studies on the matter. Adolescents seem to be at risk of smartphone addiction because they are yet to develop self-control in smartphone use. This psychometric study aimed at examining the levels of validity evidence for the Smartphone Addiction Inventory-Italian (SPAI-I) version for adults, among adolescents. Confirmatory Factor Analysis confirmed the factor structure of the SPAI-I version for adults among adolescents but not the exploratory factor structure for adults of the original Smartphone Addiction Inventory (SPAI). Convergent validity was assessed by examining the relationship between SPAI-I, self-control, and internalized and externalized problems. A total of 446 Italian adolescents (mean age = 16.04, SD = 1.72, 36.3% males) completed the Self-Restraint Subscale of the Adolescent Self-Consciousness and the Strengths and Difficulties Questionnaires—with a specific focus on the subscales of internalized and externalized problems. Present findings suggested that the SPAI-I version could be used to assess smartphone overuse among adolescents according to a multidimensional perspective.
Effect of Deformation Heating on Microstructure Evolution During Hot Forging of Ti-6Al-4V

Published: November 2021

Abstract
The effect of deformation heating on microstructure evolution during hot forging of Ti-6Al-4V was established. For this purpose, right-circular cylinders of Ti-6Al-4V with an equiaxed-α preform microstructure were preheated to a temperature between 1148 K (875 °C) and 1223 K (950 °C), and compressed to a 60-pct. height reduction in a screw press, yielding average true strain rates of ~ 5 to 20 s−1. Thermocouple measurements and corroborating finite-element-method (FEM) simulations quantified substantial deformation-heating-induced temperature increases. For all preheat temperatures, the heating transient led to an exposure above the equilibrium
β transus temperature. Despite such temperature excursions, the volume fraction of equiaxed primary α in each forged billet was only slightly lower than that in the corresponding preheated condition. The source of such observations was rationalized on the basis of the (hypothesized) solute-concentration fields that develop during the heating and cooling transients experienced in high-rate deformation processing.

Abstract
Purpose
To present the first results of intraoperative irradiation (IORT) in breast cancer with a low-energy photon system used as partial breast irradiation (PBI) or as an anticipated boost before whole breast hypo-fractionated irradiation (IORT + WBI), concerning tolerance, side effects, quality of life, and patient-reported outcomes.

Materials and methods
Eighty patients treated with an Intrabeam® system of 50 kV X-rays received a 20 Gy dose intraoperatively were included. Moderate daily hypofractionation of 2.7 Gy in 15 fractions up to 40.5 Gy was administered if high-risk factors were present. Acute post-operative toxicity, surgery complications, chronic toxicity, patient-reported cosmesis and Breast-Q questionnaire were performed at follow-up visits.

Results
Thirty-one patients were treated as PBI and the remaining 49 as IORT + WBI. Only the IORT + WBI group presented acute toxicity, mainly mild acute dermatitis (11 patients) and one subacute mastitis. A total of 20 patients presented fibrosis (18 patients grade I, 2 patients grade II), 15 (30.5%) patients in the IORT + WBI group and 3 (9.6%) patients in the group of PBI. The cosmesis evaluation in 73 patients resulted poor, fair, good or excellent in 2, 7, 38 and 26 patients, respectively. In PBI group Breast-Q scored higher, especially in terms of their psychosocial well-being (78 vs 65) and satisfaction with radiation-induced toxicity (77 vs 72, respectively) compared to IORT + WBI group.

Conclusion
IORT is a well-tolerated procedure with low toxicity, good cosmesis and favorable patient-reported outcomes mainly when administered as PBI.
Sharing Personal Information is Discounted as a Function of Social Distance
Authors: Romanowich Paul 
Published: November 2021

AbstractSocial discounting researchers have repeatedly shown that individuals discount sharing the amount of a monetary reward as a function of social distance, and that increasing the available monetary reward decreases sharing. However, no previous study has tested whether sharing nonmonetary commodities are discounted as a function of social distance. The current study tested whether sharing personal information would be discounted similarly to monetary rewards, as well as whether a magnitude effect occurred at a relatively small magnitude difference with 96 university students. A within-participant procedure showed that sharing personal information was discounted as a function of social distance, albeit with a steeper discounting rate relative to both monetary reward magnitudes. However, there was no significant association between personal information discounting rates and monetary discounting rates at either magnitude, suggesting that participants treated each commodity differently (i.e., commodity effect). Replicating previous non-U.S. samples, discounting rates for both monetary reward magnitudes were significantly positively associated with each other and showed a significant magnitude effect, with participants showing significantly steeper discounting rates for the relatively larger monetary rewards. The results for sharing personal information are important because many scams now target personal information in addition to money. Future research should examine what type of personal information is most likely to be shared as a function of social distance, and whether those participants who choose to share more personal information also are at greater risk for scams targeting personal information.
Impact of particle size reduction on high gravity enzymatic hydrolysis of steam-exploded wheat straw
Authors: Hoppert Luis , Einfalt Daniel 
Published: November 2021

AbstractEconomically feasible bioethanol production from lignocellulosic biomass requires solid loadings ≥ 15% dry matter (DM, w/w). However, increased solid loadings can lead to process difficulties, which are characterized by high apparent slurry viscosity, insufficient substrate mixing and limited water availability, resulting in reduced final glucose yields. To overcome these limitations, this study focused on enzymatic hydrolysis of 10–35% DM solid loadings with steam-exploded wheat straw in two different particle sizes. At solid loadings of 20 and 25% DM small particle size of ≤ 2.5 mm yielded 16.9 ± 1.1% and 10.2 ± 1.4% increased final glucose concentrations compared to large particle size of 30 ± 20 mm. Small particle size also positively influenced slurry viscosity and, therefore, miscibility. As a key finding of this investigation, high gravity enzymatic hydrolysis with solid loadings of 30–35% DM was indeed successfully employed when wheat straw was applied in small particle size. Here, the highest final glucose yield was achieved with 127.9 ± 4.9 g L−1 at 35% DM solid loading. An increase in the solid loading from 10 to 35% DM in small particle size experiments resulted in a 460% increase in the final glucose concentration.
Mixed E-duality for E-differentiable Vector Optimization Problems Under (Generalized) V-E-invexity
Authors: Abdulaleem Najeeb 
Published: November 2021

AbstractIn this paper, a class of E-differentiable vector optimization problems with both inequality and equality constraints is considered. The so-called vector mixed E-dual problem is defined for the considered E-differentiable vector optimization problem with both inequality and equality constraints. Then, several mixed E-duality theorems are established under (generalized) V-E-invexity hypotheses.

Published: November 2021

AbstractThe white paper first outlines the state of inequity in food security/sovereignty in our area of focus, taking into account historical context as well as emerging and ongoing effects of the COVID-19 pandemic and community and policy responses to it. We then discuss a food acquisition intervention, structured as a longitudinal, collaborative research, and service-learning effort known as Everybody Eats. The white paper provides detailed discussion of competing understandings of agriculture, horticulture, and the social problem of food insecurity; the preliminary data that has led to a current collaborative effort to enhance the skillset of people previously not understood as food producers and provisioners, but only as end-user consumers; and the new iteration of the project wherein specific sets of expertise from diverse disciplines are deployed both to offer a more robust intervention, and bring new methodologies to bear in assessing the ecology of a local foodshed. We propose mobilizing existing resources and expertise of the Land Grant/Cooperative Extension system to act as a regional hub for facilitating full community food security (caloric and nutritional adequacy) and food sovereignty (participatory decision-making regarding living spaces and culturally appropriate foodways). Finally, we illustrate how a nexus of faculty, working from a service-learning advocacy perspective and embedded in a participatory action framework, provides a mechanism for bringing together and sustaining a community of intellectually diverse researchers and stakeholders.

AbstractObjective:Physical activity (PA) is a known benefit to older adults with diabetes; however, the determinants of PA are less well studied in this population. Applying the World Health Organization’s International Classification of Functioning, Disability and Health (ICF), a well-established biopsychosocial framework, we explored PA participation among older adult with type 2 diabetes.Method:Using data from the Health and Retirement Study and the RAND Center for the Study of Aging (N = 2,016; mean age = 73.19; SD = 6.16), we conducted hierarchical stepwise regression analysis to evaluate the relative contribution of different biopsychosocial predictors to PA – namely, body functions and structure, activity and participation, personal, and environmental factors.Results:Altogether, biopsychosocial factors accounted for 20% of the variance in PA participation. Of the personal factors, high extraversion and low neuroticism explained approximately 54% of the variance in PA among the older adults – beyond sociodemographics. Low body mass index, reduced pain, reduced depression, and higher cognitive functioning also had good explanatory power (25% of explained variance), whereas activity participation and environment did not (10% each).Conclusion:Aligning care with components of the ICF will help to ensure a focus on person-centric practices and, in turn, optimize participation outcomes such as PA.

AbstractThe modern Nile delta developed in the Middle and Late Holocene, and at its most northern-central point is situated at the Burullus Lagoon, which is environmentally diverse, including salt marshes, mudflats, and sand plains, and separated from a sea by a sand barrier overtopped with high sand dunes. The lagoon has been fed since the Middle Holocene by the Sebennitic branch of the Nile and marine intrusions through the Bughaz inlet. A sediment core (BO-1) was collected at the northeastern shore of the lagoon and sampled at centennial scale resolution in order to reconstruct the development of the lagoon. The results show that an initial and limited lagoon had developed at the end of the Early Holocene, but after a dry period ca. 7.2 cal ka BP it has been progressively transformed into a marshy area, with occasional inflows of sea water. Lower water level and higher salinity of the Burullus Lagoon at 6.0–5.5 and 4.8–4.2 cal ka BP reflected droughts in the Nile catchment. Thereafter, the river reactivated in the Burullus Lagoon area, and since 2.8 cal ka BP was accompanied by occasional inflows of sea water. Since ca. 0.8 cal ka BP, increased fluvial activity occurred in this part of the Nile delta, which terminated after construction of the Aswan dams in the twentieth century.
The Cheney Flute Sonatas Manuscript: An Early Collection for the Traverso, Containing Music by Pepusch and Others
Authors: Talbot Michael 
Published: November 2021

AbstractThis article describes and evaluates a manuscript album of English provenance from the early eighteenth century containing 24 anonymous solo sonatas for the transverse flute (traverso) and continuo. These are especially interesting in that they date from a period when this still rather novel instrument had, in England, very little purpose-written repertory within that genre. A study of concordances and contextual factors reveals that a large number of them, plus some movements in pasticcio sonatas, are by J. C. Pepusch, whose musical style in solo sonatas is examined in detail. The article includes an inventory with musical incipits of the individual compositions.
Traditional Gender Attitudes, Nativism, and Support for the Radical Right
Authors: Christley Olyvia R. 
Published: November 2021

AbstractUsing data from the 2017 European Values Study, I analyze the link between harboring traditional gender attitudes and supporting radical right-wing parties. I theorize that the intrinsically gendered elements of the radical right's platforms and rhetoric, which mirror traditional masculinity and femininity in both explicit and implicit ways, make the ideology a comfortable home for individuals who hold traditional gender attitudes. My analyses reveal that gender traditionalists are more likely than egalitarians to express support for the radical right, even after controlling for a host of existing explanations. The same impact is not replicated for mainstream conservative parties. In addition, holding more gender-traditional attitudes raises the probability of supporting the radical right among both nativists and non-nativists. These findings provide important evidence that gender attitudes seemingly constitute a significant pathway to support for the radical right across Europe.
