Egg production of Baltic cod (Gadus morhua) in relation to variable sex ratio, maturity, and fecundity

Observed fluctuations in relative fecundity of Eastern Baltic cod (Gadus morhua L.) were related to food availability during the main feeding period and were used to develop a predictive model that explained 72% of the interannual variations in fecundity. Time series of sex ratios, maturity ogives, and relative fecundity were combined with mean weights-at-age and stock sizes from an analytical multispecies model to estimate the potential egg production (PEP). Relationships between PEP and independent estimates of realized daily and seasonal egg production from egg surveys were highly significant. The difference between estimates of potential and realized seasonal egg production was of a magnitude corresponding to the expected loss of eggs as a result of atresia, fertilization failure, and early egg mortality. The removal of interannual variability in sex ratio, maturity, and fecundity on estimates of PEP deteriorated the relationships in all three cases. PEP proved to be superior to spawning stock biomass as measure of the reproductive potential in a stock-recruitment relationship of Eastern Baltic cod. PEP in combination with the reproductive volume explained 61% of the variation in year-class strength at age 2

Creating Pan-Karen Identity: The Wrist Tying Ceremony in the United States

A movement to unite all Karen-language speaking people under the banner of a distinct and unified Karen identity has been afoot for more than a century. Buddhist and Christian Karens from Burma, now living in Fort Wayne, Indiana, USA, are forging – and contesting – a universal Karen identity through the celebration of the “traditional” wrist tying ceremony. This articulation of pan-Karen identity is an example of Baumann and Gingrich\u27s (2004) theory of identity construction, which they call a “grammar of encompassment.” This case study shows that the theory, which claims that instances of encompassment are often contested by the encompassed (that is, the subordinate people whose alterity is denied), must be extended. In the United States, it is the encompassers (that is, the Christians who have greater economic and political power) who are the most deeply troubled by the denial of difference demanded by the discourse of encompassment
