Cellular functions hinge on the ability of proteins to adopt their correct folds, and misfolded proteins can lead to disease. Here, we focus on the proteins that catalyze disulfide bond formation, a step in the oxidative folding pathway that takes place in specialized cellular compartments. In the endoplasmic reticulum of eukaryotes, disulfide formation is catalyzed by protein disulfide isomerase (PDI); by contrast, prokaryotes produce a family of disulfide bond (Dsb) proteins, which together achieve an equivalent outcome in the bacterial periplasm. The recent crystal structure of yeast PDI has increased our understanding of the function and mechanism of PDI. Comparison of the structure of yeast PDI with those of bacterial DsbC and DsbG reveals some similarities but also striking differences that suggest directions for future research aimed at unraveling the catalytic mechanism of disulfide bond formation in the cell.

Manipulating, or "managing," reported earnings is a temptation faced by every accountant and corporation around the world. This study investigates whether national culture influences perceptions of the acceptability of earnings management. Participants from eight countries evaluated 13 vignettes describing various earnings management practices (Merchant & Rockness, 1994). Our results demonstrate considerable variation in perceptions across nations to the earnings management scenarios, providing strong evidence that the practice of earnings management was not perceived similarly in all countries. Using Hofstede’s (1991) cultural indices, we find that the differences in aggregate perceptions across countries were not closely associated with any of the cultural dimensions examined. We do, however, find that perceptions of earnings manipulations involving the timing of operating decisions were associated with both the Power Distance Index and the Masculinity Index.

Plagiogrammaceae, a poorly described family of diatoms, are common inhabitants of the shallow marine littoral zone, occurring either in the sediments or as epiphytes. Previous molecular phylogenies of the Plagiogrammaceae were inferred but included only up to six genera: Plagiogramma, Dimeregramma, Neofragilaria, Talaroneis, Psammogramma and Psammoneis. In this paper, we describe a new plagiogrammoid genus, Orizaformis, obtained from Bohai Sea (China) and present molecular phylogenies of the family based on three and four genes (nuclear-encoded large and small subunit ribosomal RNAs and chloroplast-encoded rbcL and psbC). Also included in the new phylogenies is Glyphodesmis. The phylogenies suggest that the Plagiogrammaceae is composed of two major clades: one consisting of Talaroneis, Orizaformis and Psammoneis, and the second of Glyphodesmis, Psammogramma, Neofragilaria, Dimeregramma and Plagiogramma. In addition, we describe three new species within established genera: Psammoneis obaidii, which was collected from the Red Sea, Saudi Arabia; and Neofragilaria stilus and Talaroneis biacutifrons from the Mozambique Channel, Indian Ocean, and illustrate two new combination taxa: Neofragilaria anomala and Neofragilaria lineata. Our observations suggest that the biodiversity of the family is strongly needed to be researched, and the phylogenetic analyses provide a useful framework for future studies of Plagiogrammaceae.

Celem niniejszego tekstu jest pokazanie, w jaki sposób Batesonowskie pojęcie „metakomunikacji” jest użytecznym punktem wyjścia do analiz prowadzonych nad sposobem uprawiania komunikologii historycznej . Podejmując się analiz z zakresu historii idei komunikacji oraz filozofii komunikacji, natrafiamy na istotny problem badawczy: w jaki sposób można analizować przeszłe sposoby myślenia i komunikowania o komunikacji, jeśli komunikacja jest nieustannym procesem odnoszącym się do samego siebie. Okazuje się, że metodologiczne wyzwanie stojące przed badaczami, którzy piszą historię komunikacji w ramach dyscypliny określanej mianem komunikologii historycznej, może być wsparte rozważaniami Gregorego Batesona na temat procesu metakomunikacji. Dlatego w dalszej części niniejszego tekstu pokazuję, w jaki sposób, korzystając z ustaleń Batesona, rozwijam pojęcie metakomunikacji i aplikuję na gruncie komunikologii historycznej. Myśl Batesona jest niezwykle użyteczna do rozważań metodologicznych i może stanowić punkt wyjścia do budowania nowych narzędzi filozoficznych służących analizowaniu zmian społecznych.
