The second parent: Ideologies of childhood in Russian pedagogy manuals

The collapse of the Soviet Union saw deep reforms in the educational system and, with the new market economy, in the presuppositions about training and employment that underpinned it. But this article argues that contemporary Russian teacher training materials nonetheless reproduce Soviet understandings about childhood, education, and the state. Comparing discourses about teaching in Russian, Soviet, and American resources for prospective teachers reveals that differences between Russian and American teaching practices stem not from economic differences, but different conceptions of the social purpose of education. Discourse analysis identified patterns in representations of children and teachers in widely-used Russian teacher training textbooks, mainstream American teacher training textbooks, and Soviet pedagogical writings. This analysis revealed that contemporary Russian textbooks, in contrast to their Soviet counterparts, represent the function of education as helping prepare a child to enter society qua capitalist workforce. But the materials differ from American textbooks in their depictions of the responsibilities of teachers, the role of the state, and the rights of children in primary schools. In these respects, Russian textbooks sound much like Soviet ones

A Modified Lotka-Volterra Competition Model with a Non-Linear Relationship Between Species

In this article, we consider a modified Lotka-Volterra competition model, which incorporates a non-linear relationship representing the interaction between species. We study the qualitative properties of this new system and compare them to the qualitative properties of the classical Lotka-Volterra equations and obtain results suggesting that the modified model is a better representation of some biological situations

Analysis of Don\u27t Break the Ice

The game Don\u27t Break the Ice is a classic children\u27s game that involves players taking turns hitting ice blocks out of a grid until a block containing a bear falls. We present Don\u27t Break the Ice as a combinatorial game, and analyze various versions with an eye towards both normal and misere play. We present different winning strategies, some applying to specific games and some generalized for all versions of the game

Patterns of Habitat Use by Whooping Cranes During Migration: Summary from 1977-1999 Site Evaluation Data

We used site evaluation data collected during 1977–1999 to examine patterns of habitat use by whooping cranes (Grus Americana) during migration through the United States portion of the Wood Buffalo–Aransas flyway. We examined characteristics of 3 types of stopover habitats: 1) roost sites (n = 141 records), 2) feeding sites (n = 306), and 3) dual-use sites (i.e., where observer recorded cranes as using a site for both roosting and feeding (n = 248). Results in spring were influenced by the large number of records from Nebraska (\u3e 67% of spring records) and in fall by frequent observations on Salt Plains and Quivera National Wildlife Refuges and Cheyenne Bottoms State Wildlife Area. Palustrine wetlands were the most commonly recorded wetland system (68.8%) used by whooping cranes; riverine wetlands accounted for 21.6% and lacustrine wetlands 9.6% of site evaluation records. Riverine sites were common only in Nebraska, where they accounted for 59.0% of roost sites. All social groupings of whooping cranes used palustrine wetlands for both roosting and feeding, whereas most of the whooping cranes found on riverine roosts were single cranes or nonfamily groups. Most wetlands used by cranes were seasonally or semipermanently flooded. Observers found whooping cranes on a wide range of wetland sizes. River widths ranged from 36 to 457 m and averaged 227 ± 88 (SD) m. Maximum depths of wetlands on which observers saw cranes ranged from 3 to 305 cm and averaged 51 ± 41 cm. Specific sites within wetlands where observers recorded cranes feeding or roosting averaged 18 ± 11 cm (range 3&#;-61 cm). Observers described most wetlands as having soft substrates, low shoreline slope (\u3c 5%), and clear or turbid water. Riverine roost sites and dual-use sites were consistent in their lack of vegetation, but palustrine sites varied in types of emergent vegetation and their distribution. Feeding sites were largely upland crops, with lower occurrence of seasonal or permanent wetlands, or upland perennial cover. At dual-use sites, cranes were most often found in palustrine permanent or seasonally flooded wetlands. In spring, observers recorded cranes most frequently feeding on row-crop stubble, with lesser use of small grain stubble and green crops. In fall, observers found cranes frequently on green crops, small-grain stubble, and row-crop stubble. Woodland habitat occurred adjacent to \u3e 70% of riverine roost sites but adjacent to \u3c 8% of palustrine roost sites. All riverine roosts and about half of palustrine roost sites also had adjacent upland cover; upland cropland was common for both. The most common habitats adjacent to feeding and dual-use sites were cropland and upland perennial cover. About two-thirds of feeding sites were \u3c 0.8 km from palustrine roost sites, whereas over half of riverine roost sites were \u3e 1.2 km from feeding sites. More than two-thirds of sites where observers found cranes were \u3c0.8 km from human developments; 58% of observations were \u3e 0.8 km from utility (power or phone) lines. Visibility varied by site use and wetland system. Private ownership accounted for \u3e 80% of feeding sites used by whooping cranes; federal ownership accounted for most ownership of roost sites. More than 90% of roost sites that were under federal or state ownership were considered secure, whereas security of roosts on private lands was evenly split between secure and threatened. These observational data provide further insights into habitats used by migrant whooping cranes, but further investigations into habitat use patterns are needed

Deterministic Separation of Cancer Cells from Blood at 10 mL/min

Circulating tumor cells (CTCs) and circulating clusters of cancer and stromal cells have been identified in the blood of patients with malignant cancer and can be used as a diagnostic for disease severity, assess the efficacy of different treatment strategies and possibly determine the eventual location of metastatic invasions for possible treatment. There is thus a critical need to isolate, propagate and characterize viable CTCs and clusters. Here, we present a microfluidic device for mL/min flow rate, continuous-flow capture of viable CTCs from blood using deterministic lateral displacement arrays. We show here that a deterministic bump array can be designed such that it will isolate with efficiency greater than 85% CTCs over a large range in sizes from millimeter volume clinical blood samples in minutes, with no effect on cell vitality so that further culturing and analysis of the cells can be carried out

Resilience and depressive symptoms in adults with cardiac disease : A systematic review

Background Depressive symptoms predict hospitalization and mortality in adults with cardiac disease. Resilience, defined as a dynamic process of positively responding to adversity, could protect against depressive symptoms in cardiac disease. No systematic review has been conducted on the relationship between these variables in this population. Objective The aim of this review was to explore the association between psychological resilience and depressive symptoms in adults with cardiac disease. Methods Seven databases (PubMed, EMBASE, CINAHL, PsycInfo, Web of Science, SCOPUS, and Cochrane) were searched from inception to December 2019 using the search terms “cardiac disease,” “depressive symptoms,” “depression,” and “resilience.” Inclusion criteria dictated that studies reported original research on the association between resilience and depressive symptoms in adults with a cardiac disease broadly defined. Quality ratings were performed by 2 independent raters. Results We identified 13 studies for final review. Study sample sizes ranged from 30 to 1022 participants, average age ranged from 52 to 72 years, and all studies had majority male participants (64%–100%). Resilience and depressive symptoms were inversely related in 10 of 13 studies. The 3 studies with poor-quality sampling techniques or significant loss to follow-up found no relationship. Conclusions Resilience seems to protect against depression in adults with cardiac disease. Gaps in the literature include poor understanding of the direction of causality. Methods of promoting resilience need to be identified and studied

Servant Leadership: A Phenomenological Study Of Practices, Experiences, Organizational Effectiveness, And Barriers

The subject of leadership is complex, and one of the main issues facing organizational leaders today is how to motivate employees to actively participate in the efforts that lead to accomplishing organizational goals. This study gathered lived experiences of 15 organizational leaders who practice the servant leadership philosophy, and explored how business leaders link their servant leadership practices to their organization’s effectiveness. The qualitative responses obtained during this study indicated that the perceived organizational barriers that prevent the servant leadership practices are the organization’s culture, the fear of change, and the lack of knowledge regarding the servant leadership philosophy. This study also gained insight into the impact that these organizational barriers have on one’s ability to practice servant leadership
