A note on the Markoff condition and central words

We define Markoff words as certain factors appearing in bi-infinite words satisfying the Markoff condition. We prove that these words coincide with central words, yielding a new characterization of Christoffel words

Mediators Affecting Girls’ Levels of Physical Activity Outside of School: Findings from the Trial of Activity in Adolescent Girls

Providing after school activities is a community level approach for reducing the decline in physical activity of girls as they reach early adolescence

Antiplasmodial and antileishmanial inhibitory activity of triterpenes and steroidal alkaloid from the leaves of Funtumia elastica (Preuss) Stapf (Apocynaceae)

peer reviewedThe phytochemical study of leaves of Funtumia elastica led to the isolation of three undescribed ursane derivatives, funtumic acids A, B and C (1–3), as well as one steroidal alkaloid, elasticine (4) and five other known compounds (5–9). Their structures were elucidated on the basis of NMR, MS, IR, UV spectroscopic data as well as by comparison with the literature. The compound 5-hydroxypyridine-3-carboxamide (9) was isolated for the first time from the Apocynaceae family. All the isolated compounds were evaluated for their antiparasitic effects against 3D7 and Dd2 strains of Plasmodium falciparum and promastigotes of Leishmania donovani (MHOM/SD/62/1S). Compounds 1–4 possessed good in vitro antimalarial activities against CQR Dd2 with IC50 values ranging from 4.68 to 5.36 μg/mL and moderate on CQS 3D7. Only compounds 1 and 2 showed leishmanicidal activities with IC50 values ranging between 10.49 and 13.21 μg/mL. In addition, crude extract exhibited potent antiplasmodial (IC50 0.91 and 3.12 μg/mL) and antileishmanial (IC50 3.32 μg/mL) activities, thus demonstrating their potential synergistic action

Pathways curriculum and family interventions to promote healthful eating and physical activity in American Indian schoolchildren

Pathways, a multisite school-based study aimed at promoting healthful eating and increasing physical activity, was a randomized field trial including 1704 American Indian third to fifth grade students from 41 schools (21 intervention, 20 controls) in seven American Indian communities

Racism in the hands of an angry God : how image of God can activate or resist colorblind racism narrative frames regarding police treatment of African Americans.

Previous research suggests an angry God image is a narrative framework predicting punitive views regarding criminal justice. However, no research examines the correlation of God image to racial attitudes nor how God image is racialized. Using Bonilla-Silva’s (2017) colorblind racism framework, I perform logistic regression on a national survey to examine the correlation between an angry God image and beliefs that a) police treat Blacks and Whites equally (abstract liberalism) and b) police shoot Blacks more often because Blacks are more violent than Whites (cultural racism). I also interact angry God image with both race and religious tradition to account for the complexity of religious effects. Results suggest that the angry God narrative serves to activate the cultural racism frame for White people and adherents of historically White traditions, yet for Black persons and Black Protestants in particular, belief in an angry God serves as a form of resistance
