Mentor Social Capital, Individual Agency and Working-class Student Learning Outcomes: Revisiting the Structure/Agency Dialectic

This investigation explores factors that contributed to the disparate learning identities of two white baby-boomer brothers from the same working-class family. The research, part of a broader phenomenological study into the influences of working-class masculinities and schooling offers an insight into the individual family members’ differential communities of practice that over time had the potential to affect each brother’s accumulation and utilization of specific forms of social capital. The research challenges conventional thinking regarding the role families play in reproducing educational inequality because it recognizes that an individual’s responses to multiple experiences both within and outside the family, rather than family influence alone, are the best means of understanding certain social effects on a student’s formal schooling (Goldthorpe, 1983; Phelan, Davidson and Cao, 1991)

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

Averting biodiversity collapse in tropical forest protected areas

The rapid disruption of tropical forests probably imperils global biodiversity more than any other contemporary phenomenon¹⁻³. With deforestation advancing quickly, protected areas are increasingly becoming final refuges for threatened species and natural ecosystem processes. However, many protected areas in the tropics are themselves vulnerable to human encroachment and other environmental stresses⁴⁻⁹. As pressures mount, it is vital to know whether existing reserves can sustain their biodiversity. A critical constraint in addressing this question has been that data describing a broad array of biodiversity groups have been unavailable for a sufficiently large and representative sample of reserves. Here we present a uniquely comprehensive data set on changes over the past 20 to 30 years in 31 functional groups of species and 21 potential drivers of environmental change, for 60 protected areas stratified across the world’s major tropical regions. Our analysis reveals great variation in reserve ‘health’: about half of all reserves have been effective or performed passably, but the rest are experiencing an erosion of biodiversity that is often alarmingly widespread taxonomically and functionally. Habitat disruption, hunting and forest-product exploitation were the strongest predictors of declining reserve health. Crucially, environmental changes immediately outside reserves seemed nearly as important as those inside in determining their ecological fate, with changes inside reserves strongly mirroring those occurring around them. These findings suggest that tropical protected areas are often intimately linked ecologically to their surrounding habitats, and that a failure to stem broad-scale loss and degradation of such habitats could sharply increase the likelihood of serious biodiversity declines.Keywords: Ecology, Environmental scienc

What the Blazers? The effect of cultural symbols on class identity and learning outcomes

This paper examines the relationship between school clothing and learning identity. The paper, part of a wider, qualitative, narrative investigation into the learning experiences of white, working-class baby-boomers males, argues that an individual’s preference for types of school clothing contributes to the construction of his/her cultural and social identity. It is suggested that items of school clothing influence an individual’s either solidarity with, or distance from, school practices and peers. Cultural capital, habitus, cultural evolution and meme theory are used to understand the effects of school uniforms on individuals’ identity construction and learning outcomes. It is suggested that embodied performance not only has the potential to reflect a student's masculine competence (Connell, 2009) but it can also symbolize the individual's understanding of physical attractiveness and intelligence.

Manuscript 2012-02-02558B Averting biodiversity collapse in tropical forest protected areas

Soft object manipulation has recently gained popularity within the robotics community due to its potential applications in many economically important areas. Although great progress has been recently achieved in these types of tasks, most state-of-the-art methods are case-specific; They can only be used to perform a single deformation task (e.g. bending), as their shape representation algorithms typically rely on "hard-coded" features. In this paper, we present LaSeSOM, a new feedback latent representation framework for semantic soft object manipulation. Our new method introduces internal latent representation layers between low-level geometric feature extraction and high-level semantic shape analysis; This allows the identification of each compressed semantic function and the formation of a valid shape classifier from different feature extraction levels. The proposed latent framework makes soft object representation more generic (independent from the object's geometry and its mechanical properties) and scalable (it can work with 1D/2D/3D tasks). Its high-level semantic layer enables to perform (quasi) shape planning tasks with soft objects, a valuable and underexplored capability in many soft manipulation tasks. To validate this new methodology, we report a detailed experimental study with robotic manipulators.</p
