Narratives as Meaningful Learning Experiences
This work focuses on exploring the use of narratives as a process of communication and meaning making thereby reviewing different contributions by different research lines The questioning from narratives is a learning experience that is shaping a common space interacting with learning as a process and the beginning of critical thinking as a product Since the beginning of the process of access to reading we can stimulate the ability to question and to reflect that over time will become an essential foundation for reading for pleasure We build our common meanings based on the knowledge of reality in terms of the cultural context to which we belong Children need to read or listen to stories read to find information on any area of knowledg
Teaching Self in Process Discussion Children
This paper explores the relationship between language teaching practices of teachers and their implicit theories about purchasing on Basic Education For the study of teaching practices used observational methodology and in contrast to interview teachers which is the part analyzed in this article The results suggest that there is a relationship between what teachers think do and say in the classroom context However not all behaviors had a close relationship with the thought and not all necessarily have a strong belief advocacy to action The targets proposed by the teachers have shown a direct relation to the strategies used in the joint construction of knowledge Communicative coherence between the goals they want to achieve and develop teaching style that is observe
Imagination: A Creative Tool to Achieve Meaningful Understanding of New Information
This paper discusses how imagination mediates children s understanding of new knowledge Through a theoretical framework based on Vygotsky s concept of creative imagination this study looks at children s imagination as a way to make new information meaningful Verbal stimuli a story about the world read by four Kindergarten teachers provide grounds to investigate how children s imagination gives meaning to new information The paper reports the findings of a research project that compares and analyses the use of reading groupwork in four kindergarten schools two in Burgos Spain and two in Tampico M xico We begin by providing the theoretical stance that supports the study Next we explain the methodology used in the study The data is then discussed and interpreted While Imagination appears to be a source of information it seems to be a process generated between the teacher and the student stemming from teacher s request
Topological signature for periodic motion recognition
In this paper, we present an algorithm that computes the topological
signature for a given periodic motion sequence. Such signature consists of a
vector obtained by persistent homology which captures the topological and
geometric changes of the object that models the motion. Two topological
signatures are compared simply by the angle between the corresponding vectors.
With respect to gait recognition, we have tested our method using only the
lowest fourth part of the body's silhouette. In this way, the impact of
variations in the upper part of the body, which are very frequent in real
scenarios, decreases considerably. We have also tested our method using other
periodic motions such as running or jumping. Finally, we formally prove that
our method is robust to small perturbations in the input data and does not
depend on the number of periods contained in the periodic motion sequence.Comment: arXiv admin note: substantial text overlap with arXiv:1707.0698
Automatic Counting of Canola Flowers from In-Field Time-Lapse Images
The combination of plant phenotyping and computer techniques has gained popularity amongst breeders and computer scientists. The recent evolution of the latter has allowed High-Throughput Phenotyping (HTP) to play a significant role in filling the genotype-to-phenotype gap. While most of the related work in HTP is performed in controlled environments, such as greenhouses, that allow automatic devices to capture the data reliably, research in in-field phenotyping is not as robust due to environmental confounds (i.e., fog or sun-reflections). The usage of high temporal density data has not been exploited to the same degree as high spatial resolution information. However, many phenotypes (e.g., canola flowering) have a temporal component. In this document, we present an image-processing-based method that attempts to detect and count flowers of canola during the early flowering stage on in-field time-lapse images. This approach can be used to analyze the evolution of the flower density of canola plants over short periods of time during the first days of flowering thanks to the availability of high temporal resolution images. We used images extracted during Summer 2016 to generate ground truth, tune the flower detection method and count the flowers during the first days of the flowering period. We provide an overview and a discussion about additional steps that might be needed to overcome the impact of sunlight reflection on canola leaves in the detection of flowers
A metaheuristic approach for the repositioning problem in bike sharing systems (bss): a study case in Toluca, MĂ©xico
The impact of Bike Sharing Systems (BSS) in the world had experienced such success that nowadays most iconic cities in the world have adopted its own system. The particular characteristics of the user’s mobility in every city have not allowed developing a generalized procedure to operate the systems. Moreover, the lack of symmetry in the mobility patterns, and the dynamic users’ behavior lead to eventually “unbalance” the system, this is, to a lack of bikes at stations, and therefore bikes have to be repositioned to stations where effective demand is present, and there is no unified or scientifically supported methodology. In this paper we deal with a study case in Toluca city (Huizi system), in which the entity in charge of current operational activities wants to design a procedure scientifically based to perform repositioning daily activities at the minimum operational cost guarantying the availability of bikes for the users (service level). Due to operational requirements, this bi-objective problem was formulated using a dynamic scope and stated as a combinatorial optimization model and finally solved using a multi-objective evolutionary algorithm
Effects of Consumer Financial Protection Introduced after the Financial Crisis of 2007-2008
This paper studies the effects of consumer financial protection regulation introduced in the US after the financial crisis of 2007-2008. It starts with a review of bounded rationality in the context of retail financial markets. I analyze the survey of consumer finances using diffs-in-diffs, paying special attention to the singularities of this dataset. The main goal is to assess the effectiveness of regulatory changes. Secondarily, the paper tries to find out if deception was occurring in the marketplace. There is support for the effectiveness of the 2011 FTC advertising rule. Results reject effectiveness of HOEPA rule of 2008 and HEOA provisions about private education loans
