Part VIII Craft Projects: Carving Cute Critters (pp. 235-239). In E. Kroski (Ed.) 53 Ready-to-Use Kawaii Craft Projects

AT THE PURDUE Library of Engineering & Science, we have a variety of services, such as 3D printing, and Maker tools for check out, such as handheld 3D scanners. We use our Maker events as a way to let students know what we have available to them. To reach as many patrons as possible, on a campus of 40,000 students, we make our events mobile and call the program Mobile Making. The events revolve around the library tools and services, including the one for this project, subtractive technologies. We host projects that support the intersection of engineering, technology, and art. The Carving Cute Critters project demonstrates subtractive, CNC technology and gives students an opportunity to paint and talk to their Library faculty and staff in an informal, fun way. With Carving Cute Critters, students are given pre-carved blocks of wood to decorate with painter markers. We use the Inventables Carvey machine and their free software, Easel, but any CNC carving machine with compatible software works for this project. This is a layered activity. Participants can either decorate wood blocks and see how a tabletop CNC carving machine works, or they can take is a step further and create their own Cute Critter to be carved. We have found this to be one of our most successful events. Students are focused on painting the blocks and ask questions about the machine. We are thanked for offering the event and asked when we will hold it again

Diversity and Making: A Living History Quilt

Due to a lack of diversity found in the maker movement, makerspaces are going through an evaluation. Academic libraries have an opportunity to rebuild makerspaces and programming from a place of equity. At a University located in the Midwestern United States, the Library maker program collaborated with the Asian American and Asian Resource Cultural Center to make a quilt from printed archival photos, student photos and recorded stories. The result was a “living history” quilt that reflected Asian community and culture on campus. This paper explores diversity in making through collaboration, details of the project process and lessons learned

The Concept of a Smart Action – Results from Analyzing Information Systems Literature

In recent years, the term \u27smartness\u27 has entered widespread use in research and daily life. It has emerged with various applications of the Internet of Things, such as smart homes and smart factories. However, rapid technological development and careless use of the term mean that, in information systems (IS) research, a common understanding of smartness has not yet been established. And while it is recognized that smartness encompasses more than the use of impressive information technology applications, a unified conceptualization of how smartness is manifested in IS research is lacking. To this end, we conducted a structured literature review applying techniques from Grounded Theory. We found that smartness occurs through actions, in which smart things and individuals interact, process information, and make data-based decisions that are perceived as smart. Building on these findings, we propose the concept of a \u27smart action\u27 and derive a general definition of smartness. Our findings augment knowledge about how smartness is formed, offering a new perspective on smartness. The concept of a smart action unifies and increases understanding of \u27smartness\u27 in IS research. It supports further research by providing a concept for describing, analyzing, and designing smart actions, smart devices, and smart services

Exponential speed-up with a single bit of quantum information: Testing the quantum butterfly effect

We present an efficient quantum algorithm to measure the average fidelity decay of a quantum map under perturbation using a single bit of quantum information. Our algorithm scales only as the complexity of the map under investigation, so for those maps admitting an efficient gate decomposition, it provides an exponential speed up over known classical procedures. Fidelity decay is important in the study of complex dynamical systems, where it is conjectured to be a signature of quantum chaos. Our result also illustrates the role of chaos in the process of decoherence.Comment: 4 pages, 2 eps figure

Bandleitfähigkeit im Hofstadter‐Schmetterling

Die erlaubten Energiewerte von Elektronen in Kristallen liegen in Bändern, die auch den Stromtransport in leitfähigen Materialien bestimmen. Setzt man Kristalle einem Magnetfeld aus, so zerfallen die Bänder in ein fraktales Spektrum, den Hofstadter-Schmetterling. Wir konnten in einem künstlichen Kristallpotential in einlagigem Graphen zeigen, dass sich diese Struktur durch Oszillationen der Bandleitfähigkeit nachweisen lässt. Diese Oszillationen sind noch bei Temperaturen sichtbar, bei denen der innere Aufbau des Hofstadter-Schmetterlings schon nicht mehr zu erkennen ist

Reproducibility in Management Science

With the help of more than 700 reviewers we assess the reproducibility of nearly 500 articles published in the journal Management Science before and after the introduction of a new Data and Code Disclosure policy in 2019. When considering only articles for which data accessibility and hard- and software requirements were not an obstacle for reviewers, the results of more than 95% of articles under the new disclosure policy could be fully or largely computationally reproduced. However, for 29% of articles at least part of the dataset was not accessible to the reviewer. Considering all articles in our sample reduces the share of reproduced articles to 68%. These figures represent a significant increase compared to the period before the introduction of the disclosure policy, where only 12% of articles voluntarily provided replication materials, out of which 55% could be (largely) reproduced. Substantial heterogeneity in reproducibility rates across different fields is mainly driven by differences in dataset accessibility. Other reasons for unsuccessful reproduction attempts include missing code, unresolvable code errors, weak or missing documentation, but also soft- and hardware requirements and code complexity. Our findings highlight the importance of journal code and data disclosure policies, and suggest potential avenues for enhancing their effectiveness

Long-range three-body atom-diatom potential for doublet Li3{}_3

An accurate long-range {\em ab initio} potential energy surface has been calculated for the ground state ${}^2A'$ lithium trimer in the frozen diatom approximation using all electron RCCSD(T). The {\em ab initio} energies are corrected for basis set superposition error and extrapolated to the complete basis limit. Molecular van der Waals dispersion coefficients and three-body dispersion damping terms for the atom-diatomic dissociation limit are presented from a linear least squares fit and shown to be an essentially exact representation of the {\em ab initio} surface at large range

A Concept Study for Feature Extraction and Modeling for Grapevine Yield Prediction

Yield prediction in viticulture is an especially challenging research direction within the field of yield prediction. The characteristics that determine annual grapevine yields are plentiful, difficult to obtain, and must be captured multiple times throughout the year. The processes currently used in grapevine yield prediction are based mainly on manually captured data and rigid statistical measures derived from historical insights. Experts for data acquisition are scarce, and statistical models cannot meet the requirements of a changing environment, especially in times of climate change. This paper contributes a concept on how to overcome those drawbacks, by (1) proposing a deep learning driven approach for feature recognition and (2) explaining how Extreme Gradient Boosting (XGBoost) can be utilized for yield prediction based on those features, while being explainable and computationally inexpensive. The methods developed will be influential for the future of yield prediction in viticulture

Patterns and correlates of claims for brown bear damage on a continental scale

Wildlife damage to human property threatens human-wildlife coexistence. Conflicts arising from wildlife damage in intensively managed landscapes often undermine conservation efforts, making damage mitigation and compensation of special concern for wildlife conservation. However, the mechanisms underlying the occurrence of damage and claims at large scales are still poorly understood. Here, we investigated the patterns of damage caused by brown bears Ursus arctos and its ecological and socio-economic correlates at a continental scale. We compiled information about compensation schemes across 26 countries in Europe in 2005-2012 and analysed the variation in the number of compensated claims in relation to (i) bear abundance, (ii) forest availability, (iii) human land use, (iv) management practices and (v) indicators of economic wealth. Most European countries have a posteriori compensation schemes based on damage verification, which, in many cases, have operated for more than 30 years. On average, over 3200 claims of bear damage were compensated annually in Europe. The majority of claims were for damage to livestock (59%), distributed throughout the bear range, followed by damage to apiaries (21%) and agriculture (17%), mainly in Mediterranean and eastern European countries. The mean number of compensated claims per bear and year ranged from 0·1 in Estonia to 8·5 in Norway. This variation was not only due to the differences in compensation schemes; damage claims were less numerous in areas with supplementary feeding and with a high proportion of agricultural land. However, observed variation in compensated damage was not related to bear abundance. Synthesis and applications. Compensation schemes, management practices and human land use influence the number of claims for brown bear damage, while bear abundance does not. Policies that ignore this complexity and focus on a single factor, such as bear population size, may not be effective in reducing claims. To be effective, policies should be based on integrative schemes that prioritize damage prevention and make it a condition of payment of compensation that preventive measures are applied. Such integrative schemes should focus mitigation efforts in areas or populations where damage claims are more likely to occur. Similar studies using different species and continents might further improve our understanding of conflicts arising from wildlife damage
