Desconstruindo e Reconstruindo Linguagem, Raça e Relações de Poder em uma Sala de Aula Secundária nos Estados Unidos

In classrooms, teachers explicitly and implicitly engage students in exploring the language ideologies that influence their attitudes about language variation and race relations. The case study reported here uses detailed ethnographically informed discourse analysis to examine how the instructional conversations in a secondary language arts classroom invited students to reflect on, deconstruct, and reconstruct language ideologies that influenced how they viewed language use and race relations.  We employed a microethnographic, discourse analytic frame, informed by interactional sociolinguistics, critical race theory and raciolinguistics to analyze the instructional conversation.    The analysis made visible how the instructional conversation guided students’ deconstruction and reconstruction of language variation through positioning one another to question linguistic binaries, linkages between language ideologies and racial hierarchies, and language ideologies that lack grounding in their own everyday language experiences.  The findings also show that the students’ own social identities were implicated in the language ideologies they held, deconstructed, and reconstructed.Nas salas de aula, os professores envolvem explicitamente e implicitamente os alunos na exploração das ideologias linguísticas que influenciam suas atitudes sobre a variação da linguagem e as relações raciais. O estudo de caso relatado aqui usa análise do discurso etnogeograficamente detalhada para examinar como as conversas instrucionais em uma sala de aula de artes de língua secundária convidaram os alunos a refletir, desconstruir e reconstruir ideologias linguísticas isso influenciou a forma como eles viam o uso da linguagem e as relações raciais.  Empregamos um quadro mircoetnográfico, analítico do discurso, informado por sociolinguística interacional, teoria racial crítica e raciolinguística para analisar a conversa instrucional.    A análise tornou visível como a conversa instrucional orientou a desconstrução e a reconstrução da variação da linguagem pelos alunos através do posicionamento uns dos outros para questionar binários linguísticos, ligações entre ideologias linguísticas e raciais hierarquias e ideologias linguísticas que carecem de aterramento em suas próprias experiências linguísticas cotidianas.  Os resultados também mostram que as próprias identidades sociais dos alunos foram implicadas nas ideologias linguísticas que detinham, desconstruídas e reconstruídas

Transferring Water and Climate Resilience Lessons from Australia\u27s Millennium Drought to Southern California

Southern California and Southern Australia are two regions of the world which share many climatic, socioeconomic and demographic characteristics that lend themselves to meaningful exchanges of knowledge and innovations. With the benefit of Australia’s documented experiences, California can learn what solutions worked and did not work in Australia, potentially avoiding major pitfalls. While some changes in California are already underway, many opportunities – and challenges – still remain. California’s policymakers and residents can adopt and adapt the most fitting solutions from Australia’s experience. California, and especially Southern California, can use these to appropriately and effectively respond to the extremes of our long-term water and climate crises. In doing so, we will put California on a better path towards resilience as we navigate the challenges of drought, flood and extreme heat forecast to increase in our future. In October 2014, TreePeople and The Energy Coalition co-organized and co-led a delegation of policymakers and elected officials from throughout California to the Australian cities of Melbourne and Adelaide. These cities implemented innovative water management solutions during the Millennium Drought that helped to drought-proof their water supplies and increase resilience in anticipation of a changing climate. The goals of this delegation were to show California water leaders first-hand the drought and climate response initiatives that Adelaide and Melbourne employed and to focus on transferring and implementing viable approaches in California. This article highlights the key lessons learned from this research and provides recommendations for how Southern California can best approach transferring these lessons

Tabloids--A Tool for Public Issues Education

An old-fashioned vehicle,the tabloid-format publication remains a cost-effective method for delivering public issues education. Since 1998, three high-profile public issues have been addressed in tabloids that were distributed as inserts in all the daily newspapers in Oregon. These publications, which have multiple purposes, also have multiple payoffs. Each tabloid\u27s impact is determined by the level of public interest in the issue and by how well the publication carries out its educational objectives. A carefully managed review process allows heavily entrenched factions to be successfully engaged. Significant financial as well as human resources are required for production of a public issue tabloid

Palladium-catalyzed reactions of unactivated alkyl electrophiles

I. Palladium-Catalyzed Reactions of Unactivated Alkyl Electrophiles An overview of palladium-catalyzed reactions with sp3-hybridized electrophiles is presented. Cross-coupling reactions and carbonylations with alkyl halides and sulfonates are discussed in detail. II. Carbonylative Alkyl-Heck Type Cyclization of Alkyl Iodides A palladium-catalyzed carbonylative Heck-type cyclization of alkyl halides is described. Treatment of a range of primary and secondary alkyl iodides with catalytic palladium(0) under CO pressure forms a variety of synthetically versatile enone products. The reactivity described represents a rare example of a palladium-catalyzed Heck-type cyclization involving unactivated alkyl halides with β-hydrogens. Alkene substitution is well tolerated, and mono- and bicyclic carbocycles may be easily accessed. III. Alkyl-Heck Type Cyclizations of Alkyl Halides A palladium-catalyzed Heck-type reaction of unactivated alkyl iodides is described. This process displays broad substrate scope with respect to both alkene and alkyl iodide components and provides efficient access to a variety of cyclic products. The reaction is proposed to proceed via a hybrid organometallic-radical mechanism, facilitating the Heck-type process with alkyl halide coupling partners. IV. Palladium-Catalyzed Enantioselective Carbonylation of Alkyl Iodides A palladium-catalyzed enantioselective carbonylation of unactivated secondary alkyl iodides is reported. Preliminary results serve as proof-of-principle that hybrid radical-organometallic reactivity enables the stereoselective synthesis of α-chiral carbonyl compounds. V. Palladium-Catalyzed Ring Forming C-H Alkylations of Aromatic Systems A palladium-catalyzed intramolecular C-H alkylation of heteroarenes and arenes with unactivated alkyl halides is described. Preliminary results suggest this process is applicable to primary alkyl bromides and iodides and tolerates electron-rich and -poor aromatic systems. Our goal to be able to readily synthesize medium-ring fused aromatic structures so they can be readily applied to a variety of biologically active compounds.Doctor of Philosoph

Fit for Self-Employment? An extended person-environment fit approach to understand the work-life interface of self-employed workers

The recent growth in self-employment has sparked scholarly interest in why individuals choose and remain in self-employment. Yet, relatively little is known about how self-employed workers enact their daily lives and what this means for their work–life interface. Self-employment is often presented as a means to enhance life choice and as enabling work and nonwork activities to be combined more satisfactorily. However, extant evidence on how self-employment is experienced is mixed, with some studies reporting long and irregular working hours and high levels of stress. Furthermore, the way in which self-employment is experienced may be influenced by national context – economic, institutional and cultural factors. In this paper, we develop a multi-level model which extends existing work on the Person–Environment Fit by incorporating factors relevant to self-employment. The model assists us to understand how contextual factors create both opportunities and tensions which impact the work–life interface of self-employed workers
