Culture, Constructivism, and Media: Designing a Module on Carlos Slim
No full textMexican tycoon Carlos Slim Helú has been a fixture on Forbes’s list of billionaires since 1991, and for the past three years, he has topped the magazine’s list of the world’s richest men. Although he is exceptionally well-known in his native Mexico, the majority of American college students have never heard of Carlos Slim. This article presents a curricular module built around this charismatic and controversial figure. The module requires students to navigate Internet-supported news media in the target language (Spanish), and engages them in independent, small-group, and larger, teacher-led activities designed to foster critical and comparative skills in cultural competency and analysis through process-based, student-led inquiry. Pedagogically and methodologically, the author engages with the recommendations and conclusions of recent studies by ACTFL and MLA committees, as well as by other leading scholars, regarding both the use of technology in the classroom and the idea of “teaching culture.” The unit’s content significantly deepens and enriches students’ understanding of social, economic, and political issues in modern Mexico. The article carefully situates each stage and aspect of the curricular unit presented in relation to recent studies of constructivism in foreign language acquisition and on the hierarchy of Bloom’s taxonomy of learning objectives

Flexural behaviour of composite slim floor beams
No full text[EN] Composite slim floor beams comprise a steel section embedded in a concrete slab, offering the advantages of a steel-concrete composite structure combined with a reduced floor depth. Several mechanisms contribute to the shear connection in this type of beam, such as headed studs, friction and clamping effects and the using of reinforcement bars passing through holes in the steel beam web. However, to date, nobody has systematically identified these mechanisms and Eurocode 4 does not provide specific design guidance for slim floor beams. Hence, a series of shear beam tests and flexural beam tests were carried out in order to assess the degree of shear connection and connector capacity in these beams. The test set-up is described including different arrangements of shear connectors for each specimen. The paper presents the findings from the flexural beam tests. The results are compared with those from the previous shear beam tests. Numerical models will be developed in future to extend the data and include a wider range of parameters. The data will also be used to improve understanding of this type of beam and will lead to the provision of specific design guidelines for slim floor beams.The authors gratefully acknowledge the funding received from the European Community Research Fund for Coal and Steel under grant agreement number RFSR-CT-2015-00020.Sheehan, T.; Dai, X.; Yang, J.; Zhou, K.; Lam, D.

Reducing the lengths of slim planar semimodular lattices without changing their congruence lattices
No full textsummary:Following G. Grätzer and E. Knapp (2007), a slim planar semimodular lattice, SPS lattice for short, is a finite planar semimodular lattice having no as a sublattice. An SPS lattice is a slim rectangular lattice if it has exactly two doubly irreducible elements and these two elements are complements of each other. A finite poset is said to be JConSPS-representable if there is an SPS lattice such that is isomorphic to the poset of join-irreducible congruences of . We prove that if and is an -element JConSPS-representable poset, then there exists a slim rectangular lattice such that , the length of is at most , and . This offers an algorithm to decide whether a finite poset is JConSPS-representable (or a finite distributive lattice is ``ConSPS-representable''). This algorithm is slow as G. Czédli, T. Dékány, G. Gyenizse, and J. Kulin proved in 2016 that there are asymptotically slim rectangular lattices of a given length , where is the famous constant . The known properties and constructions of JConSPS-representable posets can accelerate the algorithm; we present a new construction
Computing Diameters in Slim Graphs
No full textWith the use of large graphs with n vertices and m edges, the current approach for computing the diameter is not efficient. We have investigated a special graph class, namely slim graphs. Slim graphs are graphs whose diameter is at least some fixed fraction of the number of vertices. This constraint allows us to prove structural features in these special graphs. Using these features, we have developed three algorithms which are asymptotically superior to diameter computation in the general case. We present the following three algorithms, for a fixed 0 < k < 1/2: a (1 − k)- approximation algorithm of the diameter in O(n+m) time; a deterministic algorithm which computes the diameter in O(n2) time and a Monte Carlo algorithm which also computes the diameter in O(n2) time
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
A note on the slim accretion disk model
No full textWe show that when the gravitational force is correctly calculated in dealing with the vertical hydrostatic equilibrium of black hole accretion disks, the relationship that is valid for geometrically thin disks, i.e., c(s)/Omega(K) H = constant, where c(s) is the sound speed, Omega(K) is the Keplerian angular velocity, and H is the half-thickness of the disk, does not hold for slim disks. More importantly, by adopting the correct vertical gravitational force in studies of thermal equilibrium solutions, we find that there exists a maximal possible accretion rate for each radius in the outer region of optically thick accretion flows, such that only the inner regions of these flows can possibly take the form of slim disks, and strong outflows from the outer region are required to reduce the accretion rate in order for slim disks to be realized
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Expanding “Communities and Collections” in the K-State Research Exchange (K-REx) to benefit the K-State Community and Beyond
No full textKansas State University has used its institutional repository, the K-State Research Exchange (K-REx), to store and share its first year experience program, K-State First, and notably its common reading program, K-State First Book. We have done so with the aim that the accessibility and preservation of these documents ensures program stability, promotes engagement with first year programming, and provides the ability to foster growth,educational opportunities, and community building outside of K-State. Moving away from research concentrated repositories and taking a more holistic approach to scholarship, especially when realizing the pedagogical significance of collaborative campus programming, institutions can showcase, discover, preserve, and grow programs that shape campus communities and engagement.
This session will provide an overview of K-REx and spotlight the digital archive of the university’s first year experience program and common reading program, K-State First Book. We will discuss the benefits and challenges to expanding the purview of your repositories. We talkthrough the types of materials we decide to host in our repository and why we share what we do. We will also provide recommendations on new ways to evaluate what belongs in institutional repositories and how this diversity can benefit your program, your institution, the community, and others
