Biology and ecology of sea catfish (Ariidae) of estuarine, lagoon and coastal ecosystems in West Africa.

J Fish Biol 2021 Apr 10. Epub 2021 Apr 10.

IRD, Univ Brest, CNRS, Ifremer, LEMAR, Plouzané, France.

The family Ariidae, sea catfish of the order Siluriformes, is widely distributed throughout the world, particularly in tropical and sub-tropical areas. The three species of Ariidae found on the coasts and estuaries of West Africa are the smoothmouth catfish Carlarius heudelotii (Valenciennes 1840), the rough-head catfish Carlarius latiscutatus (Günther 1864) and the Guinean sea catfish Carlarius parkii (Günther 1864). They have been increasingly exploited by artisanal and industrial coastal fisheries in recent decades, but there is still little information available on their ecology and biology. Read More

Searching for a paradigm shift in the research on the epilepsies and associated neuropsychiatric comorbidities. From ancient historical knowledge to the challenge of contemporary systems complexity and emergent functions.

Epilepsy Behav 2021 Apr 6:107930. Epub 2021 Apr 6.

Departamento de Psicologia, Universidade Federal de Sergipe, Brazil. Electronic address:

In this review, we will discuss in four scenarios our challenges to offer possible solutions for the puzzle associated with the epilepsies and neuropsychiatric comorbidities. We need to recognize that (1) since quite old times, human wisdom was linked to the plural (distinct global places/cultures) perception of the Universe we are in, with deep respect for earth and nature. Plural ancestral knowledge was added with the scientific methods; however, their joint efforts are the ideal scenario; (2) human behavior is not different than animal behavior, in essence the product of Darwinian natural selection; knowledge of animal and human behavior are complementary; (3) the expression of human behavior follows the same rules that complex systems with emergent properties, therefore, we can measure events in human, clinical, neurobiological situations with complexity systems' tools; (4) we can use the semiology of epilepsies and comorbidities, their neural substrates, and potential treatments (including experimental/computational modeling, neurosurgical interventions), as a source and collection of integrated big data to predict with them (e.

Life expectancy in adulthood is falling for those without a BA degree, but as educational gaps have widened, racial gaps have narrowed.

Proc Natl Acad Sci U S A 2021 Mar;118(11)

School of Public and International Affairs, Princeton University, Princeton, NJ 08544.

A 4-y college degree is increasingly the key to good jobs and, ultimately, to good lives in an ever-more meritocratic and unequal society. The bachelor's degree (BA) is increasingly dividing Americans; the one-third with a BA or more live longer and more prosperous lives, while the two-thirds without face rising mortality and declining prospects. We construct a time series, from 1990 to 2018, of a summary of each year's mortality rates and expected years lived from 25 to 75 at the fixed mortality rates of that year. Read More

The Citizenship Advantage in Psychological Well-being: An Examination of the Hukou System in China.

Demography 2021 Feb;58(1):165-189

RAND Corporation, Santa Monica, CA, USA.

Given that Chinese migrants with rural hukou status are not considered full citizens in their urban destinations, rural-urban hukou conversion signifies full citizenship attainment in urban China. We assess causal effects of three major types of urban hukou attainment-merit-, policy-, and family-based hukou conversion-on migrants' psychological well-being in middle- and later-life. We further examine how hukou matters-how periods and hukou destinations alter the values of specific urban hukou and their psychological health implications for individuals. Read More
