We develop continuous-time probabilistic models to study trajectory data consisting of times and locations of user ‘check-ins’. We model the data as realizations of a marked point process, with intensity and mark-distribution modulated by a latent Markov jump process (MJP). We also include user-heterogeneity in our model by assigning each user a vector of ‘preferred locations’. Our model extend...

core dental journals according to production and citation rates dr. sdj. ghazi mirsaeid * *assistant professor of medical library and information sciences dept., faculty of allied medical sciences and dental research center, tehran university / medical sciences. abstract background and aim: given the rapid expansion of dental journals in one hand, and limitation of resources on the other, it ma...

the purpose of this study is to examine the relationship between epistemological and motivational beliefs about mathematics among gifted students. to this end , 334 first year high school gifted students were selected through applying the otis intelligence test. epistemological beliefs questionnaire (ebq) and motivational beliefs about mathematics scale (mbms) were also used as measurement inst...

In order for students to comprehend mathematics, they must be able to think and apply learned knowledge to inform skill acquisition (Schoenfeld, 2013). Written communication is a skill that enables students to prepare to learn mathematics and express thoughts. Using qualitative case study methodology within symbolic interactionism framework, this study examined the effect of concept journaling ...

Most mathematicians consider themselves, at least to some degree, to be both educators and researchers. Yet few embrace or even respect the subject at the intersection of these fields: research in mathematics education. Mathematicians rarely apply their own logical acumen to assessment of teaching and learning, nor do they often read the vast and growing literature in educational research. They...

Overlay journals are characterised by their articles being published on open access repositories, often already starting in initial preprint form as a prerequisite for submission to the journal prior initiating peer-review process. In this study we aimed identify currently active overlay and examine characteristics. We utilised an explorative web search contacted key service providers additiona...

in this research ph.d. dissertation of kmsu were studied so that citation behavior of authors could be identified and in so doing, the core journal were introduced. the other aims of this study are determining the type, language and half life of cited journals. citation analysis in this study. to review the references and to determine the core journals, bradford law was used. the references for...
