Building on historical and discursive institutionalism, this article examines the agent-based dynamics of gradual institutional change. Specifically, using marriage equality in the United States as a case study, we examine how actors’ ideational work enabled them to make use of the political and discursive opportunities afforded by multiple venues to legitimize the process of institutional change to take off sequentially through layering, displacement, and conversion. We also pay special attention to how the discursive strategies deployed by LGBT advocates, religious-conservative organizations and other private actors created new opportunities to influence policy debates and tip the scales to their preferred policy outcome. The sequential perspective adopted in this study allows problematizing traditional conceptualizations of which actors support or contest the status quo, as enduring oppositional dynamics lead them to perform both roles in subsequent phases of the institutional change process.

AbstractThis paper, based on historical research on irrigation administration in the Dongping area and on-site investigations into its current state, explores the benefits and problems produced by two institutional changes. As a common pool resource situation, irrigation systems’ “provision” and “appropriation” are two separate issues; any institutional change must thus offer two different solutions. The study concludes that the participatory changes undertaken in the Dongping irrigation area failed, in the end, to resolve the problem of irrigation system sustainability. In particular, it proved difficult for collective action to take place around provision, which led to difficulties in operating the irrigation system.

Ainda assim, modelos que exigem dados in-situ impossibilitam sua aplicação em áreas com escassez de dados. No sentido de lidar com esse desafio, o presente trabalho apresenta uma abordagem de escolha do momento de irrigar, pelo balanço hídrico da água no solo, baseada em estimativa da evapotranspiração real (ETA) obtida com o uso conjunto de imagens multiespectrais do sensor MSI/SENTINEL-2 e dados de uma estação meteorológica pública. A área de estudo foi um pivô central localizado no munícipio de Itatinga-SP. Para a tomada de decisão do momento de irrigar, com base em um manejo por lâmina de irrigação fixa, foi feita a interpolação da fração evapotranspirativa entre os dias com imagens disponíveis para obter a ETA nos dias sem imagens por meio do seu produto com a evapotranspiração de referência. Essa abordagem captou variações climáticas essenciais para a estimativa do balanço hídrico em dias sem imagem. Destaca-se nessa aplicação conjunta sua capacidade de ser realizada sem necessitar de parâmetros específicos da cultura, do microclima ou do relevo, tornando-se interessante para regiões com escassez de dados.   Palavras-chave:  evapotranspiração, momento de irrigar, agriwater.     MAGNONI, P.

REMOTE SENSING APPLIED TO IRRIGATION MANAGEMENT IN AREAS WITH LACK OF DATA: A CASE STUDY IN A CENTRAL PIVOT IN ITATINGA-SP     2 ABSTRACT   Remote sensing-based tools allow the monitoring of water budgets over different spatial and temporal resolutions. Nevertheless, some models require in situ data, preventing their application in areas with a lack of data. To address this challenge, this work presents an approach for irrigation scheduling, based on soil water budget estimation using actual evapotranspiration (ETA) obtained using MSI/SENTINEL-2 multispectral images and data from a public meteorological station. The study area consisted of a central pivot located in the municipality of Itatinga-SP, Brazil. For decision-making of irrigation scheduling, considering a fixed irrigation rate, the evapotranspiration fraction was interpolated between the days with available images to obtain the ETA on the days without images using its product with the reference evapotranspiration. This approach captured essential climate variations for estimating the water budget on non-image days. Noteworthy in this joint application is its suitability to be performed not requiring crop-, microclimate- or relief-specific parameters, making it useful for regions with a lack of data.   Keywords: evapotranspiration, irrigation scheduling, agriwater.

Abstract This article shows how a new normative standard for public professionalism has evolved from the introduction of evidence-based practice in Danish child protective services. The concept of ‘theorization’ from institutional theory is discussed and applied as the main analytical lens to explore how new ideas are introduced, interpreted, and negotiated in the organizational field. Based on a cross-level ethnographic case study, the study traces the process of theorization and shows how actors are informed by local translations and theorizations as they challenge, negotiate and develop collective understandings in the field. Theorization is therefore conceptualized as a continuous multidirectional process of recursive intertwinement between field-level and organizational developments, which may or may not entail institutional change. The study also contributes to our understanding of changing forms of professionalism by proposing the concept ‘explicit professionalism’ as a way of capturing the new normative standard for public professional work that has evolved from the process of theorizing evidence-based practice. Explicit professionalism is both a descriptive concept and a normative ideal and, it is suggested, an important dimension of new forms of organizational and organizing professionalism, which can aid our understanding of related developments in different professional fields.
