We explored whether exposure to different kinds of comprehension tests during elementary years influenced metacomprehension accuracy among 7 th and 8 th graders. This research was conducted in a kindergarten through eighth grade charter school with an expeditionary learning curriculum. In literacy instruction, teachers emphasize reading for meaning and inference building, and they regularly ass...

The purpose of this paper is to describe the unique cognitive processes that are employed to optimize collaborative team decision making in a geographically distributed and time delayed situation. The cognitive processes will be illustrated within the context of a structural model of team collaboration. The team collaboration model has four unique but interdependent stages of team collaboration...

Modulation of the host cell’s translational machinery is a crucial part of viral infection strategies. Well-characterised mechanisms that aid viruses in manipulating translational activity include, for example, internal ribosomal entry sites, which allow viral RNA translation in the absence of some or many of the canonical host translation factors. New research shows that the nucleocapsid prote...

Pink rot, caused by Phytophthora erythroseptica Pethybr., is an important disease of potato (Solanum tuberosum L.) (20). The name of the disease describes a characteristic and diagnostic pink color that appears after infected tissue has been cut and exposed to air for 20 to 30 min (8,12,17). Other symptoms of pink rot include dark discoloration of the skin and lenticels of infected parts, purpl...

When two-dimensional Anti-de Sitter space (AdS2 ) is endowed with a non-constant dilaton the origin of the central charge in the Virasoro algebra generating the asymptotic symmetries of AdS2 can be traced back to the breaking of the SL(2, R) isometry group of AdS2 . We use this fact to clarify some controversial results appeared in the literature about the value of the central charge in these m...

OBJECTIVE The objective of this study is to estimate the seroprevalence of human brucellosis in livestock professionals and analyze the factors associated with brucellosis focusing on sociodemographic variables and the variables of knowledge and practices related to the characteristics of the activities carried out in livestock. METHODS This is a cross-sectional seroepidemiological study with...

In the May 15, 2007 issue of Cancer Research , Bai et al. (1) claimed that individuals carrying haplogroup K mitochondrial DNA (mtDNA) lineages are at significantly increased risk of developing breast cancer, whereas those bearing haplogroup U lineages have a significantly decreased risk. However, this study has a number of drawbacks. First, haplogroup K is phylogenetically nested within haplog...

July -August 2004 l MILITARY REVIEW A KEY Objective Force premise is to achieve a significant increase in operating tempo (OPTEMPO). Fundamental to increased OPTEMPO is gathering, integrating, and applying information that helps military planners anticipate and counter threats before an adversary can act. To act faster than the enemy can, the Army currently uses a procedural and cumbersome mili...

Controlling nuclear positioning within cells is crucial for many cellular processes including cell division, polarity, and motility in unicellular and multicellular organisms. Pronuclear migration, during which male and female pronuclei migrate toward the center of the zygote, is a key step for sexual reproduction and embryogenesis (Reinsch and Gönczy, 1998). In zygotes of most species, includi...
