description: Recommender systems are present in many web applications to guide our choices. They increase sales and benefit sellers, but whether they benefit customers by providing relevant products is questionable. Here we introduce a model to examine the benefit of recommender systems for users, and found that recommendations from the system can be equivalent to random draws if one relies too strongly on the system. Nevertheless, with sufficient information about user preferences, recommendations become accurate and an abrupt transition to this accurate regime is observed for some algorithms. On the other hand, we found that a high accuracy evaluated by common accuracy metrics does not necessarily correspond to a high real accuracy nor a benefit for users, which serves as an alarm for operators and researchers of recommender systems. We tested our model with a real dataset and observed similar behaviors. Finally, a recommendation approach with improved accuracy is suggested. These results imply that recommender systems can benefit users, but relying too strongly on the system may render the system ineffective.

description: For a right-angled Coxeter system $(W,S)$ and $q>0$, let $\mathcal{M}_q$ be the associated Hecke von Neumann algebra, which is generated by self-adjoint operators $T_s, s \in S$ satisfying the Hecke relation $(\sqrt{q}\: T_s - q) (\sqrt{q} \: T_s + 1) = 0$ as well as suitable commutation relations. Under the assumption that $(W, S)$ is irreducible and $\vert S \vert \geq 3$ it was proved by Garncarek that $\mathcal{M}_q$ is a factor (of type II$_1$) for a range $q \in [ρ, ρ^{-1}]$ and otherwise $\mathcal{M}_q$ is the direct sum of a II$_1$-factor and $\mathbb{C}$. In this paper we prove (under the same natural conditions as Garncarek) that $\mathcal{M}_q$ is non-injective, that it has the weak-$\ast$ completely contractive approximation property and that it has the Haagerup property. In the hyperbolic factorial case $\mathcal{M}_q$ is a strongly solid algebra and consequently $\mathcal{M}_q$ cannot have a Cartan subalgebra. In the general case $\mathcal{M}_q$ need not be strongly solid. However, we give examples of non-hyperbolic right-angled Coxeter groups such that $\mathcal{M}_q$ does not possess a Cartan subalgebra.

description: The reduction of nitrogen (N) fertilizer use is a possible greenhouse gas (GHG) mitigation option, whereas cost estimation highly depends on assumptions of the yield response function. This paper analyzes the potential and range of GHG mitigation costs with reduced N fertilizer application based on empirical yield response data for winter rye (Secale cereale L.) and rapeseed (Brassica napus L.) from field experiments from 2013 to 2020 in Brandenburg, Germany. The field experiments included four to five N rates as mineral fertilizer treatments. Three different functional forms (linear-plateau, quadratic, and quadratic-plateau) were estimated to model yield response as a function of N supply. Economic calculations were based on relevant price–cost ratios. The results indicate that the opportunity costs of applying less fertilizer and the resulting GHG mitigation thereof vary in a great range across the years and crops estimated by different yield response functions. The linear-plateau function predominantly results in lower GHG mitigation costs than the quadratic and the quadratic-plateau function. On average, over eight years, a moderate reduction of N fertilizer (up to 20 kg/ha) offers a cost-efficient option for mitigating GHG emissions below EUR 50 per ton of CO2eq, even resulting in net profit gain in some cases.

description: Significant progress has been made recently in constraining the isospin-dependent parameters characterizing the SRC (short-range correlation)-modified single-nucleon momentum distribution in neutron-rich nucleonic matter using both experimental data and microscopic model calculations. Using the constrained single-nucleon momentum distribution in a nonlinear relativistic mean field (RMF) model, we study the equation of state (EOS) of asymmetric nucleonic matter (ANM), especially the density dependence of nuclear symmetry energy $E_{\rm{sym}}(ρ)$. Firstly, as a test of the model, the average nucleon kinetic energy extracted recently from electron-nucleus scattering experiments using a neutron-proton dominance model is well reproduced by the RMF model incorporating effects of the SRC-induced high momentum nucleons, while it is significantly under predicted by the RMF model using a step function for the single-nucleon momentum distribution as in free Fermi gas (FFG) models. Secondly, the kinetic symmetry energy of quasi-nucleons is found to be $E^{\rm{kin}}_{\rm{sym}}(ρ_0)=-16.94\pm13.66\,\rm{MeV}$ which is dramatically different from the prediction of $E^{\rm{kin}}_{\rm{sym}}(ρ_0)\approx 12.5$ MeV by FFG models at nuclear matter saturation density $ρ_0=0.16\,\rm{fm}^{-3}$. Thirdly, comparing the RMF calculations with and without the high momentum nucleons using two sets of model parameters both reproducing identically all empirically constraints on the EOS of symmetric nuclear matter (SNM) and the symmetry energy of ANM at $ρ_0$, the SRC-modified single-nucleon momentum distribution is found to make the $E_{\rm{sym}}(ρ)$ more concave around $ρ_0$ by softening it significantly at both sub-saturation and supra-saturation densities, leading to an isospin-dependent incompressibility of ANM in better agreement with existing experimental data.

description: Leber's hereditary optic neuropathy (LHON) is a mitochondrial complex I disorder and causes inexorable painless vision loss. Recent studies from India reported that a significant proportion of LHON patients lack primary mitochondrial DNA mutations, suggesting that alternative genetic factors contribute to disease development. Therefore, this study investigated the genetic profile of LHON-affected individuals in order to understand the role of mito-nuclear genetic factors in LHON. A total of thirty probands displaying symptoms consistent with LHON have undergone whole mitochondrial and whole exome sequencing. Interestingly, whole mtDNA sequencing revealed primary mtDNA mutations in 30 % of the probands (n=9), secondary mtDNA mutations in 40 % of the probands (n=12) and no mitochondrial changes in 30 % of individuals (n=9). Further, WES analysis determined pathogenic mutations in 11 different nuclear genes, especially in cases with secondary mtDNA mutations (n=6) or no mtDNA mutations (n=6). These findings provide valuable insight into LHON genetic predisposition, particularly in cases lacking primary mtDNA mutations.

What Would Users Do? An Empirical Analysis of User Interaction With Online Finding Aids
Creators: name: Chapman, Joyce
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: This paper presents the findings from a usability study on the redesign of the  finding aid Web display at the Southern Historical Collection at UNC-Chapel  Hill. The study focused on how users interact with help and navigational features,  stumbling blocks presented by finding aid structure and archival terminology,  how users seek information, and what users want for the future of finding aids.  Findings show that Internet proficiency is slightly more important than archival  expertise when navigating online finding aids; novice users are able to attain a  fairly high level of archival intelligence without the help of mediators; archival  terminology proves a significant barrier only when presented without context; and  users rely heavily on the browser function ctrl + F and series titles when  searching. Interest in Web 2.0 was low for features involving modification of the  finding aid or requiring trust in other users, but relatively high for features helping  users to organize information.

description: Late on July 23, 2012, the STEREO-A spacecraft encountered a fast forward shock driven by a coronal mass ejection launched from the Sun earlier that same day. The estimated travel time of the disturbance ($\sim 20$ hrs), together with the massive magnetic field strengths measured within the ejecta ($> 100$nT), made it one of the most extreme events observed during the space era. In this study, we examine the properties of the shock wave. Because of an instrument malfunction, plasma measurements during the interval surrounding the CME were limited, and our approach has been modified to capitalize on the available measurements and suitable proxies, where possible. We were able to infer the following properties. First, the shock normal was pointing predominantly in the radial direction (${\bf n} = 0.97 {\bf e}_r -0.09 {\bf e}_t -0.23 {\bf e}_n$). Second, the angle between ${\bf n}$ and the upstream magnetic field, $θ_{Bn}$, was estimated to be $\approx 34^{\circ}$, making the shock "quasi-parallel," and supporting the idea of an earlier "preconditioning" ICME. Third, the shock speed was estimated to be $\approx 3300$ km s$^{-1}$. Fourth, the sonic Mach number, $M_s$, for this shock was $\sim 28$. We support these results with an idealized numerical simulation of the ICME. Finally, we estimated the change in ram pressure upstream of the shock to be $\sim 5$ times larger than the pressure from the energetic particles, suggesting that this was not a standard "steady-state" cosmic-ray modified shock (CRMS). Instead it might represent an early, transient phase in the evolution of the CRMS.
Readers' Advisory in North Carolina Public Libraries: Does Database Access Matter?

description: One tool that public library staff use for readers' advisory is NoveList, which until 2014 was accessible to North Carolina's public librarians and patrons through a public-private partnership known as North Carolina Libraries and Virtual Education (NC LIVE). In 2014, NoveList along with other databases were dropped from NC LIVE due to financial constraints. Public library systems in North Carolina were surveyed to investigate the impact of losing access to NoveList via NC LIVE. 95% of respondents indicated that RA is either extremely or very important to the mission of their library system. The only readers' advisory tool ranked higher than NoveList was personal knowledge of the library's collection. Seven interviews with public librarians support the findings and demonstrate the continued resourcefulness of NC's public library professionals.

Additional strange resonances from Lattice QCD

subject: FOS: Physical sciences

description: Recent Lattice QCD (LQCD) studies suggest that there are missing resonances in the strange sector of the Hadron Resonance Gas (HRG) model. By adopting the continuous Hagedorn mass spectrum, we present how different medium compositions influence the HRG predictions of conserved charge fluctuations. It is shown that missing strange resonances may be partially accounted for by applying the Hagedorn mass spectrum extracted from experimentally established hadrons. On the other hand, the strange-baryonic spectra, extracted from LQCD results for fluctuations, are found to be consistent with the unconfirmed states in the Particle Data Group (PDG) database, whilst the strange-mesonic spectrum points towards yet undiscovered states in the intermediate mass region.

title: The impact of leader’s support and leader’s sexual orientation on inclusion of gay men in the workplace: an experimental study
Creators: name: Choudhury, Abhishek Roy
Publisher: name: Memorial University of Newfoundland
Year: 2022

description: A leader who models inclusive behavior can contribute significantly toward the creation of a supportive environment for diverse members. To date, studies identifying how leader’s support for inclusion of gay men and how leader’s sexual orientation can influence inclusion of gay men are scarce. With a scenario based experimental study, I examined whether leaders’ support for inclusion of gay men and leaders’ sexual orientation have an impact on followers’ decision to hire a gay man and follower’s attitudes toward gay men co-workers. Hypotheses were tested on a sample of 149 full-time working adults of mixed occupations using two-way analysis of variance. The results showed followers are more likely to hire a gay man when their leader supports inclusion of gay men than when their leader does not support inclusion of gay men in the workplace. Results also suggested that followers are less likely to hire a gay man employee and are less likely to have positive attitudes toward their gay men co-workers when their leader is a gay man compared to when their leader is a heterosexual man. The implications of these findings are discussed.

description: We supplement the minimal supersymmetric standard model (MSSM) with vector-like copies of standard model particles. Such 4th generation particles can raise the Higgs boson mass to the observed value without requiring very heavy superpartners, improving naturalness and the prospects for discovering supersymmetry at the LHC. Here we show that these new particles are also motivated cosmologically: in the MSSM, pure Bino dark matter typically overcloses the Universe, but 4th generation particles open up new annihilation channels, allowing Binos to have the correct thermal relic density without resonances or co-annihilation. We show that this can be done in a sizable region of parameter space while preserving gauge coupling unification and satisfying constraints from collider, Higgs, precision electroweak, and flavor physics.

description: This paper analyzes content and design of 120 media center web sites.  This study's purposes are to develop a criteria list for use in developing media center web sites and to compare web sites by author type to determine if differences exist in incorporation of criteria.  The sites were analyzed on June 17 and 18, 2000 using criteria from information and library science, media center promotion, and web page design literature.  The findings show that (1) web sites meet most design criteria but not many other criteria and (2) media specialists' web sites do a better job of promotion than those authored by others.  In general, media center web sites do not promote the media center or specialist.

description: The research on on improving the accessibility of descriptive records for cultural objects is extensive. Such studies, ranging from indexing and subject access to experiments with social tagging, have historically focused primarily on art objects to the neglect of other cultural objects, however. Utilizing the Charles Kuralt Learning Center, a collection of historical objects at the University of North Carolina-Chapel Hill, this study explores the needs of a specific user group-researchers with relevant subject knowledge-when using descriptive object records for research. Three major themes emerged during the data analysis process: the contextualization of objects; the relationships between object records; and an interest in confirmation, validation, and authenticity.

description: This paper is a history of the four library buildings that housed the principle library  over the course of the University of North Carolina at Chapel Hill's history. The  four buildings are Smith Hall, Carnegie Library, Louis Round Wilson Library, and  Walter Royal Davis Library. The histories of these buildings are examined in the  context of general academic library buildings trends in the United States. Special  interest is devoted to the effects from increasing enrollment at universities,  complementary growth in the size of collections, and the changing pedagogy of  higher education. As enrollment and collections increased, and educational  techniques changed, new library buildings were needed to replace existing  buildings at the University of North Carolina at Chapel Hill. The period covered is  1853-1984.

 Distribution:— JAMMU & KASHMIR: Kishtwar, Padder region (Kumar & Sharma 2011). Kumar & Sharma (2011) reported this species as Calvatia rubroflava. Based on their original description, this species is characterized by medium-sized basidiomes with a cream to white, smooth peridium, a cream colored gleba turning yellow to olive yellow, and smooth to warted, globose basidiospores. However, the illustration clearly depicts that the spores are subglobose to ovoid and warted. Although, it is very difficult to place this species in C. rugosa due to inadequate descriptions, at present, it is treated as the same species until further study of the specimen has been carried out for verification.

description: This experiment tests the effectiveness of Chinese information retrieval using a segmenter that is developed with dictionary-based Maximum Forward Matching algorithm. IRTOOLS, an IR system developed at UNC Chapel Hill, is used as the platform. This study finds that less accurate segmentation will not necessarily yield worse information retrieval results. As a matter of fact, allowing two-character words only in the dictionary produced the best retrieval results in terms of precision and recall. Allowing longer words in the dictionary will lead to the missing of index words -- the problem of over-specification. However, long-word indexing can produce better results when the long-word is also used in queries.

This paper examined job advertisements for Chinese studies librarian in College & Research Libraries News from 2001 to 2010. It identifies job titles, locations, responsibilities, qualifications, and the experience required of potential Chinese studies librarians by analyzing the content of job advertisements. The analysis of 24 advertisements indicated that this position demands potential job candidates should have a high level of qualification. The results also showed that Chinese studies librarians have multiple responsibilities for selecting related materials, collections development, providing reference service for subject studies, cataloging, raising funding for program as well as other duties. The goal of the studies is to help library school students better prepare for their careers.

description: Proximity effect is used to generate effective topological superconductor by placing strong spin orbit interacting metals with superconducting materials, aiming to produce Majorana zero modes useful for topologically protected quantum computations. In recent experiments high $T_c$ material $\text{Bi}_2\text{Sr}_2\text{CaCu}_2\text{O}_{8+δ}$ is put in contact with a few quintuple layer thick $\text{Bi}_2\text{Se}_3$, and conflicting experimental results are reported. We use standard mean field approach to study this heterostructure, and find it is unlikely to have large proximity induced superconducting gap. The claimed observed s-wave gap might not be purely superconducting coherence gap despite its seemingly correct temperature dependence. Further study on the proximity induced bulk coherence gap and the band structure at the interface should shed light on this issue.

description: Many public libraries now have Web sites, which can be evaluated in regard to accessibility, usability, appearance, or content, among other criteria. This paper focuses on content. Sixty-six North Carolina public library Web sites were examined to see what subject matter they included, what form they took, who their audiences were, and whether the information was current. The most frequent subject matter was information about the libraries themselves, followed by electronic resources. Many of the sites included local information, including social service listings or local history resources. Almost three-quarters of the library sites included information of more general interest, including Reader's Advisory materials and Web links. Approximately a third provided user instruction materials, while five sites published unanticipated content, such as information about sister library programs.

description: Most results regarding Skorokhod embedding problems (SEP) so far rely on the assumption that the corresponding stopped process is uniformly integrable, which is equivalent to the convex ordering condition $\mathrm{U}^μ\leq\mathrm{U}^ν$ when the underlying process is a local martingale. In this paper, we study the existence, construction of Root's solutions to SEP, in the absence of this convex ordering condition. We replace the uniform integrability condition by the minimality condition (Monroe,1972), as the criterion of "good" solutions. A sufficient and necessary condition (in terms of local time) for minimality is given. We also discuss the optimality of such minimal solutions. These results extend the generality of the results given by Cox and Wang [2013] and Gassiat et al. [2015]. At last, we extend all the results mentioned above to multi-marginal embedding problems based on the work of Cox et al. [2018].

description: Cloudbasierte Bibliothekssysteme, die als Software as a Service von einem externen IT-Dienstleister betrieben werden, stellen das Bibliotheksmanagement vor neue Herausforderungen – vor allem im Hinblick auf die Gewährleistung von Datenschutz und Datensicherheit. Insbesondere die Risiken hinsichtlich Vertraulichkeit, Verfügbarkeit und Integrität der zu schützenden Daten sind andere als bei den herkömmlichen Systemen, die im Eigenbetrieb laufen, und neu zu bewerten. Am Beispiel des Alma-Sicherheitskonzepts der Berliner Universitätsbibliotheken wird ein Best Practice Sicherheitskonzept vorgestellt, das den Anforderungen des Datenschutzes in Deutschland genügt. Es beruht in seinem Kernbereich, der Gefährdungs- und Risikoanalyse, auf dem Eckpunktepapier „Sicherheitsempfehlungen für Cloud Computing Anbieter“ des Bundesamts für Sicherheit in der Informationstechnik (BSI), in dem grundlegende Risiken benannt und Anforderungen für ein hohes Sicherheitsniveau dargelegt sind.
description: Cloud-based library systems which are hosted by external IT-service providers in a Software as a Service model (SaaS) create new challenges for the library management – especially with regard to the guarantee of data protection and data security. In particular, the risks relating to confidentiality, availability and integrity of the data to be protected are different from those in conventional systems operated by the libraries themselves. These risks have to be re-evaluated. Using the example of the Alma security concept of the Berlin University Libraries, we present a best practice security concept, which complies with the requirements of data protection in Germany. In its core area, the analysis of threads and risks, it is based on the White Paper “Security Recommendations for Cloud Computing Providers” of the Federal Office for Information Security (BSI), which names basic risks and sets out requirements for a high level of safety.

description: This study details a web based survey of special collections research centers within academic research libraries. The survey was conducted to determine whether or not copyright law has had an impact on the participants' photographic reproduction services policy of on-line photographic images. As new technology provides improved access to special collections, broadening their community of researchers, adhering to copyright law is a major issue for universities. Establishing a consistent photographic reproduction policy among institutions as special collections research centers place easily downloadable, published and unpublished digital photographic images, on-line is necessary in order to protect the rights of copyright holders. The responses on the survey were analyzed using descriptive analysis. Additionally, a review of special collections websites was performed to reveal trends in photographic reproduction policies and various levels of accessibility to on-line digital photographic images.

description: Macrolygistopterus Pic, 1929: 1.
Type species: Lycus succinetus Latreille, 1811 (by monotypy).
Figure 5F, N.
Differential diagnosis: Macrolygistopterus differs from other New World Calochromini genera in the slender basal part and widened apical third of parameres. Lucaina has the similar slender basal part of the parameres but the apex is characteristically modified (Fig. 5O) and this genus has, similar to Caloptognatha, long erect setae in the elytra. Lygistopterus is distantly related and differs by its wide, parallel-sided parameres (Fig. 5K, N).
Distribution: Mexico, Central America, South America.

description: Die Anzahl der Forschungsdaten-Policies an deutschen Universitäten ist seit 2014 deutlich gestiegen und die Kurve geht kontinuierlich nach oben. Eine Besonderheit der deutschen Policies ist auf den ersten Blick ersichtlich: Es gibt keine einheitliche Bezeichnung – verwendet werden „Leitlinie“, „Grundsätze“, „Policy“, „Richtlinie“. Auch zeigen die Policies deutliche Unterschiede auf, was Umfang und Inhalte angeht. Um die Forschungsdaten-Policies an deutschen Universitäten weiter zu befördern, entwickelt die Technische Universität Berlin seit August 2017 im BMBF-Projekt „Modalitäten und Entwicklung institutioneller Forschungsdaten-Policies“ entsprechende Handlungsanleitungen. Ziel der ersten Projektphase ist die Konzeptionierung und Erstellung eines „Baukastens“ für institutionelle Forschungsdaten-Policies („Policy-Kit“). Als methodischer Ansatz werden ForschungsdatenPolicies deutscher Hochschulen gesammelt und evaluiert und mit internationalen Empfehlungen zu Forschungsdaten-Policies abgeglichen. Die Ergebnisse werden in diesem Artikel vorgestellt.
description: The number of research data policies at German universities has increased significantly since 2014 and there is a continuous trend upward. At first glance, a special characteristic of the German policies is evident: There is no single term, but there are several terms in use – “Leitlinie”, “Grundsätze”, “Policy”, “Richtlinie”. The policies also show significant differences regarding scope and content. In the course of the BMBF project “Modalities and development of institutional research data policies”, the Technische Universität Berlin is developing instructions to further promote the research data policies at German universities. The goal of the first phase of the project is the design and creation of a “construction kit” for institutional research data policies (“Policy Kit”). As a methodological approach, research data policies of German universities are collected and evaluated, and compared to international recommendations on research data policies. The results are presented in this article.

description: As a result of industry pressure, pay-for-performance initiatives, AHRQ quality  reporting measures and ARRA stimulus funding, many physician practices will be  compelled to adopt an EHR system within the next two years. When purchasing an  EHR and/or a practice management (PM) software package, it is critically important to  accurately forecast the total cost of ownership for each EHR software package being  considered. These costs can include software licensing fees, implementation support,  infrastructure upgrades and ongoing maintenance fees. This project seeks to illuminate  and educate healthcare professionals on the logic behind EHR pricing models while  simultaneously providing individualized software recommendations for practicing  clinicians based on objective vendor rankings.

 This is one of the most easily recognized and widely reported species from India. This species is closely related to C. fragilis. However, C. fragilis is clearly distinguished from C. cyathiformis in the field by having a distinctly plicate fruitbody with reduced to almost nil subgleba. Microscopically, C. cyathiformis differs from C. fragilis in the strongly echinate basidiospores with broad spines that are up to 2 μm long, whereas, C. fragilis has echinate spores with shorter spines up to 0.5 μm long (Cortez et al. 2012).
