A framework for analyzing institutional gaps in natural resource governance

In this paper we present the Inter-Institutional Gap(IIG) Framework as a novel approach to conceptualizing the often-overlooked interconnectivity of different rule-levels between formal and informal institutions in a resource system. This framework goes beyond the existing concepts of legal pluralism, institutional void, structural hole, and cultural mismatch, each of which offer valuable insights to particular gaps between formal and informal institutions, but do not sufficiently address the interaction at every rule level (i.e. constitutional choice, collective choice and operational choice rules). In order to demonstrate the potential of our framework for better understanding the underlying causes of inter-institutional gaps, we apply it to four case studies that encompass diverse geographical locations, governance scales, and social-ecological systems. Results reveal inter-institutional gaps can be created when there are unintended, unforeseen or hidden gaps between different rule hierarchies in two or more simultaneously operating institutions. More specifically we observe that: i) inter-institutional gaps are co-existing, therefore if a certain gap is identified, other gaps may be expected; ii) certain gaps may reveal latent gaps; and iii) intermediaries may be key to addressing inter-institutional gaps. In many cases, sustainable natural resource management and regulation cannot be achieved without directly addressing the inter-institutional gaps that exist between formal and informal institutions operating in the same resource system. The Framework facilitates analysis and understanding of multi-level governance structures in pursuit of addressing complex natural resource management issues

HETDEX pilot survey for emission-line galaxies - I. Survey design, performance, and catalog

We present a catalog of emission-line galaxies selected solely by their emission-line fluxes using a wide-field integral field spectrograph. This work is partially motivated as a pilot survey for the upcoming Hobby-Eberly Telescope Dark Energy Experiment (HETDEX). We describe the observations, reductions, detections, redshift classifications, line fluxes, and counterpart information for 397 emission-line galaxies detected over 169 sq.arcmin with a 3500-5800 Ang. bandpass under 5 Ang. full-width-half-maximum (FWHM) spectral resolution. The survey's best sensitivity for unresolved objects under photometric conditions is between 4-20 E-17 erg/s/sq.cm depending on the wavelength, and Ly-alpha luminosities between 3-6 E42 erg/s are detectable. This survey method complements narrowband and color-selection techniques in the search for high redshift galaxies with its different selection properties and large volume probed. The four survey fields within the COSMOS, GOODS-N, MUNICS, and XMM-LSS areas are rich with existing, complementary data. We find 104 galaxies via their high redshift Ly-alpha emission at 1.9<z<3.8, and the majority of the remainder objects are low redshift [OII]3727 emitters at z<0.56. The classification between low and high redshift objects depends on rest frame equivalent width, as well as other indicators, where available. Based on matches to X-ray catalogs, the active galactic nuclei (AGN) fraction amongst the Ly-alpha emitters (LAEs) is 6%. We also analyze the survey's completeness and contamination properties through simulations. We find five high-z, highly-significant, resolved objects with full-width-half-maximum sizes >44 sq.arcsec which appear to be extended Ly-alpha nebulae. We also find three high-z objects with rest frame Ly-alpha equivalent widths above the level believed to be achievable with normal star formation, EW(rest)>240 Ang.Comment: 45 pages, 36 figures, 5 tables, submitted to ApJ

ESG in focus: the Australian evidence

Addressing ESG issues has become a point of interest for investors, shareholders, and governments as a risk management concern, while for firms it has become an emerging part of competitive strategy. In this study, a database from an independent ratings agency is used to examine, longitudinally, how Australian Securities Exchange (ASX) 300 firms are responding to ESG issues. Following institutional theory predictions, ASX300 firms are improving ESG performance over the 2002–2009 timeframe. Furthermore, over this timeframe, performance on the governance dimension improved at a greater rate than environmental or social performance, as predicted. Lastly, high impact industries are predicted to demonstrate overall improved ESG performance relative to medium or low impact industries over the timeframe, but this hypothesis was not confirmed. Results are discussed along with implications and future research directions
