description: Wie kann Ökonomik Ideale guten Wirtschaftens aufgreifen, ohne ideologisch zu werden? Die Perspektiven verschiedener ökonomischer Forschungsprogramme auf COVID-19 verdeutlichen die Komplementarität positiver und normativer Ökonomik: (Normative) Ideale bieten Orientierung für (positive) Forschung. Unterbleibt jedoch ein Abgleich der Werte, die eine ökonomische Frage relevant machen, mit denen, die bei der Entwicklung der Theorie bzw. zur Analyse der Frage Pate standen, entsteht Ideologie. Das Konzept der Evidenzbasierung aus Medizin und Public Health könnte diesen Abgleich fördern.

description: Globally, parents and children in same-gender parent families are impacted by a multitude of laws related to parental sexual orientation. These sexual orientation laws vary considerably from one country to another, ranging from full legal recognition of the family structure in some countries to its criminalization in others. The psychological consequences of this legal vulnerability for family members warrant consideration in clinical practice, as they likely interfere with parental mental health, family functioning, and healthy child development. However, a systematic evidence synthesis of the pertinent literature and its placement within a broader psychological model are currently lacking. Accordingly, the aims of this review are (1) to systematically review qualitative and quantitative evidence on the impact of sexual orientation laws and the resulting legal vulnerability of same-gender parent families in key domains (individual health, family functioning and parenting, child educational and cognitive outcomes) and (2) to place these findings within a broader model integrating theories related to sexual minority health as well as family functioning and parenting. We will retrieve published and unpublished records of quantitative and qualitative studies via a systematic database search (PubMed, Scopus, Web of Science) as well as forward and backward searches of eligible studies and key literature. Mixed method data synthesis will follow a data-based convergent synthesis design. Specifically, we will use thematic synthesis to generate descriptive and analytical codes, which we will place within an integrative model informed by sexual minority health, family functioning, and parenting models. Implications for clinical and therapeutic practice will be discussed.
Sound waves induce Volkov-like states, band structure and collimation effect in graphene

description: We find exact states of graphene quasiparticles under a time-dependent deformation (sound wave), whose propagation velocity is smaller than the Fermi velocity. To solve the corresponding effective Dirac equation, we adapt the Volkov-like solutions for relativistic fermions in a medium under a plane electromagnetic wave. The corresponding electron-deformation quasiparticle spectrum is determined by the solutions of a Mathieu equation resulting in band tongues warped in the surface of the Dirac cones. This leads to a collimation effect of electron conduction due to strain waves.

description: Twenty nine potsherds from nine Neolithic sites of Northeast India have been analysed using thin section petrography. The primary objectives of this article are to determine their provenance, to investigate the production techniques of Neolithic pottery and to understand the technical skills of the ancient potters of the studied region. Based on their mineralogical content and the composition of the matrices, the pottery samples have been classified into eleven fabric groups. The analysis of the fabrics showed dissimilarities in the processing and production of ceramics which were otherwise very similar at first sight. The dissimilarities provided indications of the clay sources and the occurrence of natural and artificial temper/inclusions, e.g., organic or inorganic substances used by the Neolithic potters of Northeast India during manufacturing processes. In all fabric groups, we found ironbearing materials which show that the ancient potters used local clay to make pottery because the soil in this region contains a high amount of ferruginous substances. The results also confirmed that the analysed pottery was probably fired below 800 °C under an oxidizing atmosphere and also revealed the use of non-plastic inclusions, such as sand, quartz and organic materials during pottery production.

description: Abstract We surveyed occurrence and activity of large and medium-sized mammals on three experimental short-rotation coppice (SRC) and three afforestations by camera trapping. Both habitat types were surveyed simultaneously in spring. Additional wintertime surveys were performed on the SRC to consider seasonal aspects of habitat utilisation. In spring, SRC and afforestations were predominantly used by the same species. European hare (Lepus europaeus) and roe deer (Capreolus capreolus) were the most active species across all sites. Additionally, the European rabbit (Oryctolagus cuniculus) showed intense activity on one SRC site. Activity of carnivorous and omnivorous species was comparatively low in both habitat types, but even lower on the SRC. The only forest-associated species (European badger Meles meles), detected on all afforestations, was absent from the SRC. In winter, the surveyed SRC were used by the same species as in spring. Most species showed similar activity on the SRC in both seasons. We conclude that small-scale and structurally diverse SRC provide suitable habitat, in different seasons, especially for herbivorous mammals associated with farmland and forest-ecotones rather than forest species. The extent to which our results can be generalised to large-scale commercial SRC is unclear. However, the results indicate that SRC can be managed in a manner compatible with wildlife and may then have a habitat function for mammals comparable to that of young afforestations. Creation of within-plantation heterogeneity can be a suitable measure to improve habitat quality and should, therefore, be considered in the design and management of SRC.
On the effective oxygen yield in the disks of spiral galaxies

description: The factors influencing chemical evolution of galaxies are poorly understood. Both gas inflow and gas outflow reduce a gas-phase abundance of heavy elements (metallicity) whereas the ongoing star formation continuously increases it. To exclude the stellar nucleosynthesis from consideration, we analyze for the sample of 14 spiral galaxies the radial distribution of the effective yield of oxygen $y_{eff}$, which would be identical to the true stellar yield (per stellar generation) $y_o$ if the evolution followed the closed box model. As the initial data for gas-phase abundance we used the O/H radial profiles from Moustakas, Kennicutt, Tremonti et al. (2010), based on two different calibrations (Pilyugin & Thuan 2005 (PT2005) and Kobulnicky & Kewley 2004 (KK2004) methods). In most of galaxies with the PT2005 calibration, which we consider as a preferred one, the yield $y_{eff}$ in the main disk ($R \ge 0.2~R_{25}$, where $R_{25}$ is the optical radius) increases with radius, remaining lower than the empirically found true stellar yield $y_o$. This may indicate the inflow of low-enriched gas predominantly to the inner disk regions, which reduces $y_{eff}$. We show that the maximal values of the effective yield in the main disks of galaxies, $y_{eff,max}$, anti-correlate with the total mass of galaxies and with the mass of their dark halo enclosed within $R_{25}$. It allows to propose the higher role of gas accretion for galaxies with massive halos. We also found that the radial gradient of oxygen abundance normalized to $R_{25}$ has a tendency to be shallower in the systems with lower dark halo to stellar mass ratio within the optical radius, which, if confirmed, gives evidences of the effective radial mixing of gas in galaxies with the relatively light dark matter halo.

Does the Customer Review of Airbnb Homes Correspond to their Aspect Scores? Sentiment Analysis using a Proposed Sentence-to-aspect Relevance Model.
Creators: name: Lan, Tianlin
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: Most Airbnb homes have high ratings with a large proportion of positive reviews from users. However, the Airbnb website only releases the rating score of each aspect for each home. The aspect scores given by each reviewer are not available on the website. It is possible that the overall aspect score does not really reflect users’ sentiment as represented in their comments about that aspect. This paper proposes a methodology for finding the correspondence between aspect scores of Airbnb homes and the sentiments of their reviews. I set the sentiment analysis at the sentence level and proposed a sentence-to-aspect relevance detection approach for subjectivity classification step. The distributions of the sentiment polarities found in aspect-relevant for both the cleanliness and the location aspect show an apparent correspondence between review text and the aspect score.

title: Risk Analysis of Emergency Supply Chains
Creators: name: Chukwuka, O
Publisher: name: Liverpool John Moores University
Year: 2023

description: Unknowns and uncertainties are integral to any disaster relief operation. Activities of the emergency supply chain are usually performed in highly volatile environments and are prone to risks. Due to the complexity of the operating relief environment, relief organizations can only anticipate some supply chain disruptions. As such, they must take a comprehensive and proactive approach to uncertainties to manage multiple unexpected events. Therefore, this research aims to develop a comprehensive framework for risk management in emergency supply chains. This study adopts a comprehensive and rigorous procedure to explore the risk factors and mitigation strategies for emergency supply chains. The research design is divided into three phases; first, the risk factors and mitigation strategies are collected through an extensive literature review; next, the risk factors and risk mitigation strategies are verified with experts through high-level surveys and semi-structured interviews. Finally, based on the weight of risk factors estimated using the fuzzy analytic hierarchy process, risk factors mitigation strategies to overcome the risk factors are prioritized using the fuzzy technique for order performance by similarity to ideal solution that considers uncertainty and impreciseness rather than a crisp value. This study found and verified 28 emergency supply chain risk factors, which are categorised into two main categories: internal and external risks; four sub-categories: demand, supply, infrastructural, and environmental risks; and 11 risk types: forecast, inventory, procurement, supplier, quality, transportation, warehousing, systems, disruption, social, and political risks. War and terrorism, the impact of follow-up disasters, poor relief supplies, and sanctions and constraints that hinder stakeholder cooperation and coordination are the most significant risks. Finally, eight risk factor mitigation strategies; strategic stock, prepositioning of resources, collaboration and coordination, flexible transportation, flexible supply bases, logistics outsourcing, flexible supply contracts, and risk awareness/knowledge management were proposed and prioritised to overcome the risk factors so decision-makers can focus on these mitigation strategies. This study provides a more efficient, effective, robust, and systematic way to overcome risk factors and improve the effectiveness of emergency supply chains in disaster relief operations. This study is the first to objectively identify, categorise, and analyse emergency supply chains’ risk nature and frequency. Practitioners and policymakers can use the research findings to spot significant risk factors and appropriate mitigation strategies to reduce their effects. The risk profile will be a new database of risk factors affecting the emergency supply chain and allow stakeholders to immediately identify the disrupted emergency supply chain component.

 This thesis examines the impact of the Rural Sales Programme on the empowerment of women in Bangladesh. This study involves in-depth investigations of saleswomen’s lives who belong to a patriarchal society and are subjected to cultural and religious norms. My research shows various dimensions of women empowerment and factors that encompassed or underlay an Impact of the Rural Sales Program. Rural sales programme involving women is relatively new and was first introduced in Bangladesh in 2005. There has not been much research done on this. The impact of the Rural Sales Programme called JITA on the empowerment of women with a similar socio-economic background is emphasised in this study. The bargaining and empowerment theoretical framework toward gender and development concept has been employed alongside ethnographic methodologies which include field visits, participant observation, semi-structured interviews, and storytelling sessions with the saleswomen. This research has been conducted in ten different villages in the rural Tangail district in Bangladesh in 2015. An ethnographic style study was employed to understand the impact of rural sales programmes on participating women on different dimensions of empowerment. However, an important finding of this research is about women gaining confidence to set foot in the commercial arena outside their role as saleswomen. Face-to-face interviews were conducted with twenty rural saleswomen in their own sales territories, followed by detailed storytelling and participant observation. The findings of this research indicate that the saleswomen were empowered in the household with self-dignity and their social status, as well as their level of confidence, have uplifted since joining JITA.

description: Quantum capacity, as the ultimate transmission rate of quantum communication, is characterized by regularized coherent information. In this work, we reformulate approximations of the quantum capacity by operator space norms and give both upper and lower bounds on quantum capacity, and potential quantum capacity using interpolation techniques. We identify a situation in which nice classes of channels satisfy a "comparison property" on entropy, coherent information and capacities. The paradigms for our estimates are so-called conditional expectations. These generally non-degradable channels admit a strongly additive expression for $Q^{(1)}$. We also identify conditions on channels showing that the "hashing bound" is optimal for the cb-entropy. These two estimates combined give upper and lower bounds on quantum capacity on our "nice" classes of channels, which differ only up to a factor 2, independent of the dimension. The estimates are discussed for certain classes of channels, including group channels, Pauli channels and other high-dimensional channels.

description: Overall, this project examines the role of future self-continuity and temporal self-comparison in motivation, psychological adjustment (specifically, well-being), and emotion regulation. It also investigates the how the different components of future self-continuity relate to each other, how different types of temporal self-comparison relate to each other, and how future self-continuity and temporal self-comparison relate to each other. The main idea is that when individuals feel greater psychological connectedness to their future self, they engage in more self-affirming and less self-deflating types of temporal self-comparison, which has a positive impact on well-being, motivation, and emotion regulation. As we developed most of these ideas back in 2016 and 2017, we realize we should have preregistered this hypotheses a long time ago. Now, at least, we have a lot of preliminary data supporting these predictions.

Well-posedness of a Mixed Hemivariational-Variational Problem
Creators: name: Sofonea, Mircea
Publisher: name: Zenodo
Year: 2024

description: We consider a mixed hemivariational-variational problem, i.e., a system which gathers a hemivariational inequality with a constrained variational inequality. We list the assumptions on the data and prove the existence of a unique solution to the problem. Subsequently, we prove the continuous dependence of the solution with respect to the data. Then, we deduce a criterion of convergence to the solution of the mixed hemivariational-variational inequality, i.e., we formulate necessary and sufficient conditions which guarantee the convergence of a sequence to the unique solution of the system. The proof of our results is based on the particular structure of the problem which allows us to employ a fixed point argument. Finally, we provide two examples which illustrate our abstract results.

description: Research work is now subject to comply with FAIR principles. Additionally, it is also subject to the practices of Open Science. Different stakeholders e.g. DFG are setting the goals of reproducible research work. This not only requires the adequate handling of data but also the record of related information and practices during the research work. Therefore, different tools and workflows are being developed and suggested to achieve the goals of good research and its data management. Those tools and workflows facilitate researchers and ease the research management tasks e.g. by the means of standardisation, automation of processes and record of corresponding information. The researches of now a days are interdisciplinary and work collaboratively where participants are located at distinct locations, belongs to different domains and have different levels of competencies. In such cases, provision of tools and specification of workflows is not enough. Just like other management, good research data management is a skill that need to be taught to the researchers in a systematic and detailed way. So that they could make right decisions where and when needed. As a result, the contents and the materials for the education of good research data management become important. In this presentation, mainly approaches to deliver good RDM practices are presented. The presented approaches and experiences, which may be attributed to didactic and pedagogy methods, are based on the work for the Information infrastructure project which is part of DFG funded Collaborative Research Centre, TRR277 AMC. AMC is hosted by TU Munich and TU Braunschweig. It is an interdisciplinary center where researchers are using and generating heterogeneous, large amount of data. During the work we collaborated with LRZ, Gauss-IT center and the libraries of both universities. In this presentation, common skills and understanding that every researcher should know before and during the course of research work are listed and presented on one hand. On the other hand, skills and knowledge relating to the common aspects of RDM systems are addressed. Additionally, contents and methodologies for both in person and online as well as for hybrid environments to increase acceptance and understanding are presented. In conclusion, the skills which relates to the pre-research learning and the practices relating to good RDM are emphasised. Therefore, such contents could be suggested for teaching to the future researchers and data stewards during the regular academic discourse. The presented contents and strategies may also be adopted for small projects to large scale CRC projects.
Semantic Interoperability of Moving Image Records in Aggregating Digital Repositories: A Comparative Study of Dublin Core and PBCore Descriptive Metadata Schemas
Creators: name: Evans, Emma
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: This study examines the Dublin Core and PBCore metadata schemas as they are applied to publicly-accessible moving image records in four aggregating digital repositories. This research was conducted to determine which schema is optimal for moving image description based on the schemas’ level of semantic interoperability. In the context of this analysis, semantic interoperability is defined as the complete and consistent interpretation of elements across records.Twenty-five records were sourced from each repository. Each record was mapped to the metadata schema employed by its repository. The selected records and their crosswalks were then analyzed for completeness and consistency. Upon comparing the analyses of the Dublin Core-based records and the PBCore-based records respectively, it can be determined that both schemas face interoperability issues in the description of moving image records. Thus, optimality of a particular schema for moving image description must be discerned within the context of each particular use.
Readers’ Advisory in the Public Library: A Look at the Promotion of Diverse Literature to Teens

Year: 2019

description: Teens are reading, and libraries are helping teens read. One way that libraries are helping teens read is through readers’ advisory, the recommendation of books to readers for the purpose of pleasure reading. In the library field, there is a recognition of the need for diverse literature and its positive impacts. This study investigates the perspectives of librarians and library staff on readers’ advisory, with special attention to the promotion of diverse literature. Interview data and document analysis showed that librarians are performing readers’ advisory often, and teens are taking advantages of the different advisory opportunities provided by the libraries. The librarians view diverse literature as valuable and do promote it, though none cited promoting diverse literature as a guiding principle in readers’ advisory.

description: We prove an old conjecture by Duff, Nilsson, Pope and Warner asserting that the NS-NS sector of supergravity (and more general the bosonic string) allows for a consistent Pauli reduction on any d-dimensional group manifold G, keeping the full set of gauge bosons of the G x G isometry group of the bi-invariant metric on G. The main tool of the construction is a particular generalised Scherk-Schwarz reduction ansatz in double field theory which we explicitly construct in terms of the group's Killing vectors. Examples include the consistent reduction from ten dimensions on $S^3\times S^3$ and on similar product spaces. The construction is another example of globally geometric non-toroidal compactifications inducing non-geometric fluxes.

description: Green communications have witnessed significant attention being paid to the next generation of wireless systems research and development. This is due to growing use of sensor- and battery-oriented smart wireless devices. The related literature in green communications for next-generation wireless systems majorly relies on transmission and sensing power management, but lacks a fault-tolerant centric approach. In this context, this paper presents a fault-tolerant and reliable green communications framework for next-generation wireless systems (FRGNWS). Firstly, maximum node-disjoint routes from all source nodes to the base station are identified based on the hybrid adapted grey wolf sine cosine optimizer. Secondly, a fault-tolerant and reliable route is selected from the maximum disjoint routes for each sensor node to the base station based on the hybrid adapted grey wolf whale optimizer. The performance of our proposed green communications framework is assessed by simulation experiments considering a realistic implementation scenario and different metrics. Simulation results clearly validate the efficacy of the proposed green communications framework as compared to the state-of-the-art techniques.

description: To understand under which conditions thermodynamics emerges from the microscopic dynamics is the ultimate goal of statistical mechanics. Despite the fact that the theory is more than 100 years old, we are still discussing its foundations and its regime of applicability. A point of crucial importance is the definition of the notion of thermal equilibrium, which is given as the state that maximises the von Neumann entropy. Here we argue that it is necessary to propose a new way of describing thermal equilibrium, focused on observables rather than on the full state of the quantum system. We characterise the notion of thermal equilibrium, for a given observable, via the maximisation of its Shannon entropy and highlight the thermal properties that such a principle heralds. The relation with Gibbs ensembles is brought to light. Furthermore, we apply such a notion of equilibrium to a closed quantum systems and prove that there is always a class of observables which exhibits thermal equilibrium properties and we give a recipe to explicitly construct them. Eventually, we bring to light an intimate connection of such a principle with the Eigenstate Thermalisation Hypothesis.

description: Web 2.0 technology in archive and special collections is more popular than ever.Existing literature on the concept of social media use in archives and other cultural institutions remains adamant that a good return on investment (ROI) is the result of diligent planning and habitual evaluation of social media platforms. The purpose of this research paper is to determine through five interviews around the state of North Carolina if there is any room for deviation from this calculated plan. The results were that while there was some divergence in the methods from existing literature, it was not significant enough to disprove it as the only sure method.

 The importance of migration as a social and political concern has intensified significantly, and migration has become a highly debated topic in Europe and the rest of the world.

 Although in many EU countries migrants fill existing and emerging gaps in the labour force, and therefore tend to have a positive impact on the economic development of these countries, there seems to be a growing fear that the current levels of migration are unsustainable.

 As international migration has major implications for societies and economies, forward-looking analyses of migration are valuable tools for many domains of policy making.

description: We present an experimental and theoretical viewpoint on the electronic carrier mobilities of typical hybrid organic-inorganic perovskites (HOIPs). While these mobilities are often quoted as high, a review of them shows that although otherwise the semiconducting properties of HOIPs are impressively good, mobilities of HOIPs used in most solar cells are actually not that high. This is especially apparent if they are compared to those of inorganic semiconductors used in other high efficiency solar cells. We critically examine possible causes and focus on electron-lattice coupling mechanisms that are active at room temperature, and can lead to carrier scattering. From this, we propose scattering due to acoustic phonons or polarons as possible causes, but also point out the difficulties with each of these in view of additional experimental and theoretical findings in the literature. Further research in this direction will contribute to making HOIP solar cells even more efficient than they already are.

description: The landscape of art history publishing has vastly shifted in the past decade as it transitions to a digital world. While various constraints have hindered the growth of digital art history publishing, cultural institutions have now started to create comprehensive publications. This paper presents a content analysis of three different art history publishing platforms: the Getty Institute’s Online Scholarly Catalogue Initiative, Canadian Online Art Book Project, and Artifex Press. The results of the study show that the majority of the publications focus on white, male, Western artists reinforcing canonical ideas of art history. Important structural trends are apparent from the analysis that can be utilized to examine future publications. The conclusion of the paper highlights the various new publications that have emerged since the start of the project, further reinforcing the idea that art history publishing is truly at a tipping point in regard to the proliferation of digital formats.

description: Ionization threshold energies of Al$_n$ (n=32-95) nanoclusters are determined by laser ionization of free neutral metal clusters thermalized to several temperatures in the range from 65 K to 230 K. The photoion yield curves of cold clusters follow a quadratic energy dependence above threshold, in agreement with the Fowler law of surface photoemission. Accurate data collection and analysis procedures make it possible to resolve very small (few parts in a thousand) temperature-induced shifts in the ionization energies. Extrapolation of the data to the bulk limit enables a determination of the thermal shift of the polycrystalline metal work function, found to be in excellent agreement with theoretical prediction based on the influence of thermal expansion. Small clusters display somewhat larger thermal shifts, reflecting their greater susceptibility to thermal expansion. Ionization studies of free size-resolved nanoclusters facilitate understanding of the interplay of surface, electronic, and lattice properties under contamination-free conditions.

description: Actions of senior leaders are placed under a magnifying glass. Thus, leader failures get more attention, which could lead to negative evaluations and, ultimately, dismissal. There is evidence suggesting that women are harmed more than men by this disproportionate attention to failures, because of the incongruency between stereotypes of a ‘good’ woman and a ‘good’ leader (Eagly & Karau, 2002). Stereotypically, women are expected to behave ‘warm’ and ‘communal’, while leaders are expected to be agentic (Rudman & Glick, 2001). Indeed, Gupta et al. (2020) found that, after controlling for firm performance, female CEOs were 45% more likely to be dismissed than male CEOs. Additionally, research suggests that female leaders are held to higher ethical standards than men. For example, junior women suffer stronger legal punishment than men for ethical violations at work (Kennedy, McDonnell, & Stephens, 2016). Moreover, when an organization makes an ethical transgression, people are less likely to buy from this company if the organization is female- compared to male-led (Montgomery & Cowen, in press; Wei & Ran, 2019). However, it is not clear that such findings translate directly to the dismissal of female leaders. Indeed, it is possible that power shields women from their usual stereotypes (Pike & Galinsky, in press). Thus, we will further examine if evaluation of senior leader failures are gendered, and whether this translates into different dismissal likelihoods. Examining this issue is important because it adds clarity to the debate about the ability of women to solidify and maintain their seniority within organizations.
Bewitched, Bothered and Bewildered: The Allure of Misinformation is a Postmodern Healthcare Age

description: Misinformation is publicized as the next big public health crisis. Its exploitative nature allows it to both embed in seemingly legitimate facets of public discourse and disrupt public health initiatives. It collectively influences individual health decisions through a strategy of personal, message-oriented and emotional narrative. Utilizing the lens of vaccines, specifically the controversy surrounding the HPV vaccine in North Carolina, this study illuminates on health misinformation as an instigator of public conversation, vaccine hesitancy, and its subversion of evidence-based authority. This study provides a comparative analysis of both public and legislative perspectives, revealing a mismatch between the information needs of the public and the information written into state vaccine law. The findings offer a preliminary step towards understanding how misinformation persists in the public sphere and affords insights into how public health can evolve to better encourage autonomous health decision-making, minimizing the influence misinformation holds over its audience.
