This paper examines the nature of person complementarity in Eastern Canadian Inuktitut (Eskimo-Aleut), arguing that despite its apparent patterning as a Person Case Constraint (PCC) effect, it is not due to the presence of a defective intervener blocking person agreement with a lower argument, as is often the case in other languages. Instead, the observed effect is caused by a defective or missing person probe on C that cannot value local person features on absolutive arguments. Given the use of the PCC as a diagnostic for differentiating clitics and agreement, this result has implications for the proper identification of φ-marking in Inuktitut.

This article examines black criminal agency in the context of drug trafficking and territorial control by the Primeiro Comando da Capital (First Capital Command, PCC), a self-identified criminal organisation in São Paulo's favelas. It argues that black youth's racialised encounters with the police shape their political praxis in the city. Since in the racial imaginary, they are constantly linked to crime and violence, and since their criminalised status justifies mass incarceration and death by the police, criminality appears as a valid category to better understand not only their fate but also their agency. Ethnographic fieldwork carried out in 2009 and 2010 in a hyper-impoverished, predominately black slum community, along with weekly visits to a local detention centre in São Paulo, informs the author's analysis of the PCC's controversial languages of resistance and the gendered and racialised outcomes that emerge from their attempts to fend off the state in such topographies of domination.

The objective of the present study was to investigate the nuclei of human sperms that failed to fertilize human oocytes after intracytoplasmic sperm injection (ICSI). The sperms were injected into mouse oocytes by a piezo-micromanipulator, and some of these oocytes were artificially activated with strontium chloride (SrCl2) after ICSI. The oocytes were fixed, stained, and subjected to chromosomal analysis. The survival rate of mouse oocytes injected with infertile human sperms was 92.0% (46/50), while that of the control mouse oocytes injected with fertile human sperms was 73.6% (81/110). The rate of two pronuclei (2PN) formation was 0 (0/46) by the infertile sperms and 81.5% (66/81) by the fertile ones, a significant difference (p<0.01). Sperm chromosomes in non-activated oocytes were present as premature chromosome condensation (PCC). Artificial activation after ICSI increased the 2PN formation rate in the infertile group to 90.3% (28/31). The results of the present study suggest that infertile sperms have a low potential to spontaneously activate oocytes and to form pronuclei. Thus, artificial activation after ICSI may rescue oocytes fertilized with infertile human sperms that do not produce 2PN. The present study proved the usefulness of mouse oocytes as specimens in evaluating the oocyte-activating capacity of objective human sperms prior to ICSI treatment.
