Latent class analysis can identify unmeasured mutually exclusive categories (class membership) among participants for either observed categorical or continuous variables. More recently, latent class analysis has been applied to accelerometry to better understand the day-to-day patterns of physical activity and sedentary behavior. Typically, the class assignments are only relevant to the study f...

Municipal and agricultural pollution affects the Rio Grande, a river that separates the United States from Mexico. Three hundred and twenty-two Escherichia coli isolates were examined for multiple antibiotic resistance phenotypes and the prevalence of class 1 and class 2 integron sequences. Thirty-two (10%) of the isolates were resistant to multiple antibiotics. Four (13%) of these isolates con...

For a long period the theory of modules over rings on the one hand and comodules and Hopf modules for coalgebras and bialgebras on the other side developed quite independently. In this talk we want to outline how ideas from module theory can be applied to enrich the theory of comodules and vice versa. For this we consider A-corings C with grouplike elements over a ring A, in particular Galois c...

This essay examines the activism and scholarship of two South African sociologists Studies professors, Bernard Magubane Anthony Ngubo during their time as graduate students at UCLA in 1960s. Focusing on Ngubo, I argue that migrant from Southern Africa used research protest politics to contest postwar racial liberal ideology dominated studies sectors civil rights anti-apartheid movements Califor...

The concept of a Hopf algebra originated in topology. Classically, Hopf algebras are defined on the basis of unital modules over commutative, unital rings. The intention of the present work is to study Hopf algebra formalism (§1.2) from a universal-algebraic point of view, within the context of entropic varieties. In an entropic variety, the operations of each algebra are homomorphisms, and ten...

the relationship between asthma and sinusitis has been proposed in many reports but the role of sinus surgery in their treatment is still controversial. therefore, the effect of functional sinus surgery in patients with controlled asthma was evaluated. fifty six patients with a history of sinusitis in whom maximum medical treatment had failed and also those with a history of asthma who were in ...

OBJECTIVE The authors aimed to characterize distinct trajectories of knee pain in adults who had, or were at high risk of, knee osteoarthritis using data from two population-based cohorts. METHOD Latent class growth analysis was applied to measures of knee pain severity on activity obtained at 18-month intervals for up to 6 years between 2002 and 2009 from symptomatic participants aged over 5...

East Asian ESL students in the United States are frequently perceived as reticent, timid, and unsociable class activities discussions. The article reports a literature review investigating possible causes of actual condition students’ participative performance finds out feasible accommodations to provide them. Cultural background, foreign language anxiety, classroom norms, gender/age discussed ...
