© 2022 by authors; licensee EJSME by Bastas.This study aimed to elicit middle school preservice mathematics teachers’ self-reported web of knowledge recalled in generating mathematically rich and contextually realistic problems. We designed this study as multi-tier design research incorporated into two teacher education courses in which 40 preservice teachers enrolled in total. Preservice teachers worked in small groups and recorded the characteristics of mathematically rich and contextually realistic problems. They were also asked to produce webs of knowledge recalled in this process. Preservice teachers’ individual reflection papers, audio records of their group discussions and interviews were analyzed to understand how different types of knowledge in their web of knowledge function in relation to the mathematical richness and contextual realness aspects of the problems. The findings indicated that preservice teachers could identify various characteristics for mathematical richness and contextual realistic aspects of the problems. In relation to those characteristics, the preservice teachers’ self-reported web of knowledge produced three core knowledge types for ensuring mathematical richness (i.e., knowledge of content, curriculum, and pedagogy) and two aspects of realistic contexts (i.e., real life knowledge and interdisciplinary knowledge). Furthermore, although they included common knowledge types, the webs of knowledge were in different shapes and indicated various relationships (i.e., hierarchical, categorical, influential, and holistic.). Considering the various relations indicated by the webs of knowledge, we claimed that teachers needed an interconnected knowledge base for mathematically rich and contextually realistic problems, the implications of which we discussed for mathematics teacher education.

Analysis of FCNC ΞqQ → Λql+l- decay in light-cone sum rules
Alıyev, Tahmasıb; Savcı, Mustafa; Bilmiş, Selçuk (2022-8-01)
© 2022 authors. Published by the American Physical Society.The weak decays of doubly heavy ΞQQ baryon induced by flavor changing b→d and c→u flavor changing neutral current within the light-cone sum rules are studied. The sum rules are constructed and analyzed for the corresponding transition form factors using the parallel components of the light-cone distribution amplitudes for ΛQ baryon. Having the results for the form factors, the corresponding branching ratios for ΞQQ→ΛQl+l- decays are estimated. While...
Determination of the spectroscopic parameters of beauty-partners of Tcc from QCD
Alıyev, Tahmasıb; Savcı, Mustafa; Bilmiş, Selçuk (2022-04-01)
© 2022 authors. Published by the American Physical Society.Motivated by the recent discovery of a new tetraquark Tcc+ state with two charm quarks and two light quarks by LHCb Collaboration, we calculate the spectroscopic parameters; namely, the mass and residues of beauty partners of Tcc+ within QCD sum rules. The obtained results are compared with the predictions of different approaches in the literature.
Activity-Based Photosensitizers with Optimized Triplet State Characteristics Toward Cancer Cell Selective and Image Guided Photodynamic Therapy
Kilic, Eda; ELMAZOĞLU, ZÜBEYİR; Almammadov, Toghrul; KEPİL, DİLAY; Etienne, Thibaud; Marıon, Antoıne; Günbaş, Emrullah Görkem; Kolemen, Safacan (2022-01-01)
© 2022 The Authors. Published by American Chemical Society.Activity-based theranostic photosensitizers are highly attractive in photodynamic therapy as they offer enhanced therapeutic outcome on cancer cells with an imaging opportunity at the same time. However, photosensitizers (PS) cores that can be easily converted to activity-based photosensitizers (aPSs) are still quite limited in the literature. In this study, we modified the dicyanomethylene-4H-chromene (DCM) core with a heavy iodine atom to get two ...
Mobility and the Role of Pedestrian in the Making of Public Space: The Case Study of Mersin

© 2022 The Authors. Published by ELSEVIER B.V. This is an open access article under the CC BY-NC-ND license (https://creativecommons.org/licenses/by-nc-nd/4.0)Public spaces, being inevitable components of cities, are evolving spaces that transform, expand or shrink. Ideally, they should be publicly-owned and controlled, equally accessible to all, and function in the public interest. As the main actor of public spaces, this research aims to reveal the roles of pedestrians’ behaviour and mobility in making pu...
