The Jurisdictional Difficulties of Defining Charter-School Teachers Unions Under Current Labor Law

As charter schools have flourished in form, they have also evolved in variety: parents can send their children to a trilingual immersion school or a school whose classes meet entirely online. The same flexibility that charters offer as an alternative to traditional public schools also makes them difficult to classify for purposes of labor law. When charter-school teachers form a union, it is not clear why the National Labor Relations Board (NLRB), and not a state labor analogue, should have jurisdiction over a charter-school labor dispute. And yet, the NLRB has asserted jurisdiction in most charter-school cases. This Note examines the NLRB’s test for determining whether the broad protections of the National Labor Relations Act apply to a group of workers in the context of charter-school employees. It proposes a more robust test for differentiating between charter schools for purposes of the Act, and it applies the test to two charter schools

The canopy cover Webmap of the United Kingdom’s towns and cities

Urban trees and other green infrastructure are advocated as a cost-effective sustainable solution to ameliorate the socio-economic and environmental challenges of urbanisation. UK research has only recently started to quantify urban trees. Tree canopy cover percentage (TCC) is a useful indicator of tree presence. Its estimation can be reproducible, simple, fast, and cost-effective; it can also be evaluated through citizen science, improving people’s appreciation for urban trees and widening the data collection resource pool. This research summarises a citizen science assessment of the TCC of the UK’s 5,749 urban wards. Descriptive statistics are presented spanning local authority to country. The area-weighted mean (and standard error) of TCC across urban wards was 17.3 ± 0.1%. Nationally, the TCC were 11.8 ± 0.5%, 15.7 ± 0.5%, 17.5 ± 0.2%, and 18.1 ± 0.5%, for Northern Ireland, Scotland, England, and Wales, respectively. Results show that only 27.6% of urban wards had a TCC higher than 20%, previously suggested as a minimum target for UK towns. The findings highlight substantial geographical variance in TCC equity, as well as a negative correlation between TCC and deprivation. This information will be of value in urban forest strategy and management

Mapping past human land use using archaeological data: A new classification for global land use synthesis and data harmonization

In the 12,000 years preceding the Industrial Revolution, human activities led to significant changes in land cover, plant and animal distributions, surface hydrology, and biochemical cycles. Earth system models suggest that this anthropogenic land cover change influenced regional and global climate. However, the representation of past land use in earth system models is currently oversimplified. As a result, there are large uncertainties in the current understanding of the past and current state of the earth system. In order to improve repre- sentation of the variety and scale of impacts that past land use had on the earth system, a global effort is underway to aggregate and synthesize archaeological and historical evi- dence of land use systems. Here we present a simple, hierarchical classification of land use systems designed to be used with archaeological and historical data at a global scale and a schema of codes that identify land use practices common to a range of systems, both imple- mented in a geospatial database. The classification scheme and database resulted from an extensive process of consultation with researchers worldwide. Our scheme is designed to deliver consistent, empirically robust data for the improvement of land use models, while simultaneously allowing for a comparative, detailed mapping of land use relevant to the needs of historical scholars. To illustrate the benefits of the classification scheme and meth- ods for mapping historical land use, we apply it to Mesopotamia and Arabia at 6 kya (c. 4000 BCE). The scheme will be used to describe land use by the Past Global Changes (PAGES) LandCover6k working group, an international project comprised of archaeologists, historians, geographers, paleoecologists, and modelers. Beyond this, the scheme has a wide utility for creating a common language between research and policy communities, link- ing archaeologists with climate modelers, biodiversity conservation workers and initiatives.publishedVersio

The status quo of digital humanities in Sweden : past, present and future of digital history

A current Swedish review of digital history claims that research in digital history in Sweden is almost absent.[1] This statement must naturally be considered in the light of how the field is defined, and in this article we choose a broad definition consisting of the aggregate domain of studies in which digital material and tools are used to study the past. Digital history is without a doubt a more active field in English-speaking academic settings, but there are a number of well-established projects and initiatives in Sweden. The case studies presented in this article are cross-disciplinary and might therefore not define themselves as strictly (or solely) digital history. This may, however, be irrelevant in the post-disciplinary context. The digitization of historical source material has increasingly compelled Swedish historians to navigate in digital environments. This increased accessibility and the capacity for digitally processing historical material hold great potential for empowering research. While on the one hand, considerable growth can be expected in the coming years as technology becomes more accessible, user-friendly and domain science orientated [2], on the other hand, the expansion of digital archives and the development of digital tools are already posing new challenges for historians. Knowledge and understanding of digital media needs to be augmented considerably in order to fully take advantage of contemporary research opportunities and challenges. This essay will discuss how the creation of data and the use of new digital tools might support a variety of types of historical research, primarily by looking at developments in digital humanities (hereon DH) and digital archaeology. The variegated realm of DH practices, with their background in humanities computing and computing linguistics, will be used as a point of departure. Internationally, DH often uses the concept of labs to describe environments designed for the use of data and tools in interdisciplinary research.[3] Centres of DH have primarily been created in the USA and, more recently, in Europe. While on-going research in multiple fields, using digital data and tools, is contributing important new knowledge and developing infrastructures which are advancing the study of history; there is, of course, considerable room for improvement, both in terms of the efficiency of the tools and the scope of their application. This article will present two Swedish examples of interdisciplinary and collaborative lab spaces which are currently involved in research on the past. The more disciplinary practices of digital archaeology and digital history will also be examined in order to flag out current historically orientated research which may fall under the umbrella of DH. The essay will conclude by discussing some potential future directions.Published 2014-10-23Screens as MaterialHistory Educatio
