description: L’Australia occupa una posizione primaria all’interno della ripartizione Africa, Asia, Oceania e Antartide con oltre la metà degli aventi diritto di voto. Compito di questo capitolo è quello di analizzare l’offerta elettorale, la partecipazione e le scelte di voto degli italiani nel Nuovissimo Continente tenendo presente le dinamiche di vecchie e nuove mobilità alla ricerca di segnali di continuità e cambiamento. Il capitolo esordisce con alcune considerazioni sul profilo demografico degli italiani agli antipodi, sottolineando quanto questo sia il prodotto di diverse espressioni di italianità. Il capitolo passa poi in rassegna le scadenze elettorali politiche dal 2006 al 2013 con l’obiettivo di tracciare dinamiche di voto e mercato elettorale. L’ultima sezione è dedicata alle recenti elezioni del 2018 ed esamina patterns di continuità col passato non sottovalutando, al tempo stesso, interessanti punti di discontinuità.

[English translation] With over half of those entitled to vote, Australia occupies a primary position within the sub-division of Africa, Asia, Oceania and Antarctica. The aim of this chapter is to analyse the electoral offer, the participation and voting choices of Italians in the Newest Continent. This chapter will analyse the dynamics of old and new mobility in search of signs of continuity and change. It begins with some considerations on the demographic profile of Italians at the antipodes, underlining how much this is the product of different expressions of Italianness. The chapter then reviews the elections from 2006 to 2013 with the purpose of tracking voting dynamics and candidatures. The last section is dedicated to the recent elections of 2018. It assesses patterns of continuity with the past while not underestimating interesting points of discontinuity.
The dust properties of galaxies at the peak of cosmic star formation rate with ALMA
Creators: name: Cunha, Elisabete Da
Publisher: name: Zenodo
Year: 2020

description: The physical properties of interstellar dust grains at high-redshifts are still poorly known, and for simplicity dust is usually assumed to have the same properties as Milky-Way dust. However this assumption remains completely untested, leading to potential systematics in the way we correct for the effects of dust attenuation in observations of distant galaxies, and to inconsistencies with models of dust formation and evolution in early galaxies. One of the most poorly-understood parameters is the dust emissivity. In this talk, I will present new measurements of the dust emissivity index in z~2.5 galaxies enabled by sensitive observations at 2mm with the Atacama Large Millimetre Array (ALMA). I will demonstrate that low-frequency observations are crucial to constrain this parameter and I will discuss our results in the context of dust evolution models.

description: Studies explaining immigrant integration policies commonly focus on single aspects such as right-populist party politics or the immigration legacy of a country. This neglects the overall character of the democratic system within which policy-making unfolds. Research on empirical patterns of democracy, in turn, suggests that consensus democracies pursue ‘kinder and gentler’ policies and outperform majoritarian democracies in terms of minority representation. The article tests whether this conclusion holds for the specific group of immigrant minorities and analyses the relationship between patterns of democracy and immigrant integration policy using a new dataset on empirical democracies in 30 European and North American countries. Simultaneously estimating the character of democratic systems in terms of power dispersion and its effect on integration policies, the analysis reveals a distinct ‘Janus-faced’ pattern: while proportional power dispersion tends to coincide with more inclusive immigrant integration policies, pronounced veto structures tend to foster exclusion.
Tracing star formation (and not) on resolved galactic scales

description: The star-formation rate (SFR) of galaxies is one of the key parameters in understanding their evolution, yet issues still exist in measuring the SFR, including extinction by dust and the specific calibration of the tracer. I will introduce results from our PHANGS collaboration using MUSE, ASTROSAT, HST and ground-based imaging showing how, on ~100 pc scales, we can resolve the individual tracers of star-formation such as Halpha, UV, dust (extinction and emission) and determine how these direct and indirect tracers, with different timescale correlations relate and break-down as a function of scale and environment.

description: Wetlands are the most productive natural ecosystems in the world, and methane (CH4) emissions from wetlands are a significant source of CH4 to the atmosphere. We estimated CH4 emissions from wetlands in China, and analyzed the influence of wetland type and climate zone on CH4 emission. The results indicate that CH4 fluxes were significantly different among different types of wetlands. All types of wetlands other than coastal wetlands were found to be sources of CH4. CH4 fluxes from highest to lowest were as follows: rice paddies > marsh wetlands > reservoirs > riverine wetlands > lake wetlands > coastal wetlands. The interaction between the wetland type and the climate zone was also significant. CH4 emissions from certain types of wetlands differed in different climate zones. Lake wetlands were more sensitive to climate than other types. CH4 fluxes from marsh wetlands were similar in different climate zones, and CH4 fluxes from rice paddies were all very large because they are consistently flooded and shallow. CH4 fluxes were significantly related to both latitude and longitude, but to a greater degree to latitude since latitude is related to climate. In summary, both the wetland type and the climate zone should be considered when estimating CH4 fluxes from wetlands in China as well as in other countries.

description: The multi-phase nature of outflows is poorly known. Here we explore outflow properties using MgII and NaID absorption compared to H-alpha in emission in clumpy z~0.2 star-forming galaxies that are high redshift analogs selected from the DYNAMO survey. Understanding how outflow properties differ for different gas tracers is key to truly constraining mass outflow rates, and their dynamic and multi-phase nature.

description: Fluidized catalytic cracking (FCC) units in refineries process heavy feedstock obtained from crude oil distillation. While cracking feed, catalysts get deactivated due to coke deposition. During catalyst regeneration by burning coke in air, nitrogen oxides (NOx) are formed. The increase in nitrogen content in feed over time has resulted in increased NOx emissions. To predict NOx concentration in flue gas, a reliable model for FCC regenerators is needed that requires comprehensive understanding and accurate kinetics for NOx formation. Based on the nitrogen-containing functional groups on coke, model molecules are selected to study reactions between coke-bound nitrogen and O2 to form NO and NO2 using density functional theory. The reaction kinetics for the proposed pathways are evaluated using transition state theory. It is observed that the addition of O2 on coke is favoured only when the free radical is present on the carbon atom instead of nitrogen atom. Thus, NOx formation during coke oxidation does not result from the direct attack by O2 on N atoms of coke, but from the transfer of an O atom to N from a neighbouring site. The low activation energies required for NO formation indicate that it is more likely to form than NO2 during coke oxidation. The favourable pathways for NOx formation are identified that can be used in FCC models.

How HI populates haloes : Simulations vs Observations
Creators: name: Chauhan, Garima
Publisher: name: Zenodo
Year: 2020

description: Atomic Hydrogen (HI) plays an important role in galaxy formation and evolution, along with acting as a tracer of the underlying dark matter distribution. HI intensity mapping (21-cm intensity mapping) is a novel method where one aims to map out the distribution of HI without resolving individual galaxies - thus giving us an opportunity for a statistical study of the HI evolution across cosmic time. During this talk, I will be presenting a new HI-Halo mass scaling relation which will enable us to link the HI found in intensity mapping with the underlying dark matter. We are well aware that the HI-halo mass relation is not a straight-forward one, and there is a huge scatter behind the relation that is not seen. We aim to understand the secondary physical drivers behind this scatter and how they can be constrained with the available and upcoming surveys. We use semi-analytic model of galaxy formation SHARK built on the LCDM SURFS suite of N-body simulations for our study, using different resolutions for a more robust picture. Our new HI-Halo mass scaling relation will be accounting for these secondary properties and will enhance our understanding of how HI is populating the dark matter haloes, and how these can be probed by our current and future surveys.

description: Fixed-dose combinations (FDCs) offer significant advantages to patients and the pharmaceutical industry alike through improved dissolution profiles, synergistic effects and extended patent lifetimes. Identifying whether two active pharmaceutical ingredients have the potential to form a drug-drug cocrystal (DDC) or interact is an essential step in determining the most suitable type of FDC to formulate. The lack of coherent strategies to determine if two active pharmaceutical ingredients that can be co-administered can form a cocrystal, has significantly impacted DDC commercialisation. This review aims to accelerate the development of FDCs and DDCs by evaluating existing experimental, knowledge-based and computational cocrystal screening methods; the background of their development, their application in screening for cocrystals and DDCs, and their limitations are discussed. The evaluation provided in this review will act as a guide for selecting suitable screening methods to accelerate FDC development

Mapping Outflows and the CGM in Starbursting Disk Galaxies

Publisher: name: Zenodo
Year: 2020

description: I will present results from our recent observations of outflows and the circumgalactic medium (CGM) in star-bursting galaxies from the Keck Cosmic Web Imager. Understanding how gas cycles through galaxies is necessary for describing fundamental aspects of galaxy evolution, such as how the star formation rate evolves over cosmic time. However, outflows are extremely difficult to spatially resolve at z~1-2. Galaxies at z>1 look different to local Milky Way-like spirals, with high star formation surface densities, gas fractions and turbulent motions. We therefore also expect their outflows to be different from those measured in the local universe. Our team is using a rare sample of nearby galaxies with properties well-matched to main-sequence galaxies at z~1-2. We are measuring the spatial distribution of outflows and their chemistry in these galaxies at sub-kpc resolution. Our pilot observations reveal that (1) outflows are ubiquitous, with all lines-of-sight having gas flows at 300pc resolution; and that (2) the strongest outflows are higher than typically observed in local spirals of a similar mass. These results are different from local observations, which find that outflows are concentrated in the centre of galaxies. I also present (3) a novel technique in which we combine the outflow kinematics with measurements of metallicity to identify areas of the galaxy experiencing accretion. This new method allows us to directly observe the details of the accreting gas. For example, we find that accreting gas is more highly ionised than gas in the disk or halo, possibly indicating that it is shocking as it enters the disk.

description: Museology is balanced between a colonialist and logocentric past and a present in which the great decolonial debates are on the agenda. Collaborative work and research have become almost mandatory since the New Museology. This article questions the limits of collaborative work and the very proposal of museology to build a decolonized science. Therefore, two examples of collaborations between indigenous people and the Museu Paraense Emílio Goeldi, and a perception of a shaman in the Musée de l’Homme in Paris will be addressed. The cases concern three Amazonian indigenous groups from distinct linguistic families: Mebêngôkré, Baniwa, and Yanomami. From the discussions raised, it is concluded why collaborative work is insufficient for the construction of a decolonial museum science.

description: Background: Older adults with postlingual sensorineural hearing loss (SNHL) exhibit a poor prognosis that not only includes impaired auditory function but also rapid cognitive decline, especially speech-related cognition, in addition to psychosocial dysfunction and an increased risk of dementia. Consistent with this prognosis, individuals with SNHL exhibit global atrophic brain alteration as well as altered neural function and regional brain organization within the cortical substrates that underlie
auditory and speech processing. Recent evidence suggests that the use of hearing aids might ameliorate this prognosis. Objective: The objective was to study the effects of a hearing aid use intervention on neurocognitive and psychosocial functioning in individuals with SNHL aged ≥55 years.
Methods: All aspects of this study will be conducted at Swinburne University of Technology (Hawthorn, Victoria, Australia). We will recruit 2 groups (n=30 per group) of individuals with mild to moderate SNHL from both the community and audiology health clinics (Alison Hennessy Audiology, Chelsea Hearing Pty Ltd). These groups will include individuals who have worn a hearing aid for, at least, 12 months or never worn a hearing aid. All participants would be asked to complete, at 2 time points (t) including baseline (t=0) and follow-up (t=6 months), tests of hearing and psychosocial and cognitive function and attend a magnetic resonance imaging (MRI) session. The MRI session will include both structural and functional MRI (sMRI and fMRI) scans, the latter involving the performance of a novel speech processing task. Results: This research is funded by the Barbara Dicker Brain Sciences Foundation Grants, the Australian Research Council, Alison Hennessy Audiology, and Chelsea Hearing Pty Ltd under the Industry Transformation Training Centre Scheme (ARC Project #IC140100023). We obtained the ethics approval on November 18, 2017 (Swinburne University Human Research Ethics Committee protocol number SHR Project 2017/266). The recruitment began in December 2017 and will be completed by December 2020.

The dark side of quiescent galaxies: secondary correlations between halo mass and galaxy properties at fixed stellar mass
Creators: name: Sonnenfeld, Alessandro
Publisher: name: Zenodo
Year: 2020

description: Dark matter plays a fundamental role in galaxy evolution, by setting the gas accretion rate and temperature in the early phases of galaxy formation and, later on, by determining the merger rate between galaxies. One consequence of the causal link between the assembly history of halos and that of galaxies is the existence of correlations between the properties of these two components. One such example is the stellar-to-halo mass relation, which, given the complexity of galaxy evolution, we expect to be the one-dimensional projection of a more general relation that we wish to determine. We used weak gravitational lensing observations from the KiDS ESO public survey to explore how the dark matter halo mass of massive quiescent galaxies depends on stellar mass, size, central velocity dispersion and age. We found that, at fixed stellar mass, galaxies that have quenched more recently tend to be more extended, have a lower velocity dispersion and a smaller dark matter halo mass. Our results suggest that the mechanism responsible for quenching is more tightly connected to the mass of the dark matter halo than it is to the mass of the stellar component.

The cold neutral and molecular gas in the Small Magellanic Cloud
Creators: name: Jameson, Katie
Publisher: name: Zenodo
Year: 2020

description: The Small Magellanic Cloud (SMC) provides the only laboratory to study the detailed physics of star formation and the interstellar medium relevant to the high redshift universe. Not only is the transition from warm to cold neutral gas a rate limiting step to the formation of molecular gas, but it appears to influence star formation efficiency globally. We present first results from a new HI and using the ATCA cold atomic gas temperature and fraction at low metallicity. The survey includes 55 sources in the SMC, which doubles the number of existing observations with up to 5x greater sensitivity and 4x higher spectral resolution than previous absorption line studies. These measurements of the optical depth allow us to constrain the amount of "CO-faint" gas that is optically thick HI. We find an average cold HI cloud temperature of 30 K, lower than in the Milk Way, and a cold atomic gas fraction of ~20% for the SMC, which is similar to the Milky Way and the Local Group. ALMA ACA CO observations revealed that many regions with cold atomic gas have little CO emission and possibly no molecular gas. I will also present preliminary results from a new large (1 deg x 0.5 deg) ALMA ACA CO map of the Southwest Bar of the SMC, which shows previously undetectable small (~ 2 pc) molecular gas clumps are found throughout the region.
The Emergence of Bulges and Disks in the Universe.
Creators: name: Hashemi, Hosein
Publisher: name: Zenodo
Year: 2020

description: Fundamentally, galaxies consist of different components with different physics. The two most significant components could be considered as disk and bulge. Having different studies at the local Universe, we know that the dynamic, star formation, kinematic and stellar population in these two components are different. So the question is what physical processes and evolutionary history have leaded galaxy components to the shape we observe today? By structural decomposition of galaxies over a high dynamic range in both redshift and stellar mass, I investigate how the most resolved imaging data from the Hubble Space Telescope in COSMOS/DEVILS field can help us to disentangle galaxies into their components and study the evolution of mass and size of the components. This will tell us how the components of galaxies assemble their mass and how they relate to their size. Such a mass and size exploration of the components of galaxies might reveal how/why we see a heterogeneous population of galaxies having at least two very disparate ingredients.
Molecular gas kinematics in turbulent, gas-rich galaxies
Creators: name: Girard, Marianne
Publisher: name: Zenodo
Year: 2020

description: The molecular gas is very difficult to resolve in high-redshift galaxies. Therefore, most of the surveys have instead observed emission lines tracing the ionised gas to study the kinematics at this epoch. I will present results of two strongly lensed z~1 main-sequence galaxies and from a nearby galaxy sample, called DYNAMO, showing similar gas fraction, kinematics, and morphology to high-redshift main-sequence galaxies. Using our recent ALMA, MUSE and Gemini observations, we compare the molecular and ionised gas kinematics in these galaxies at high spatial resolution (few hundred parsec in our z~1 galaxies) to better understand the origin of the turbulence in the galaxy disks at this epoch. We observe a discrepancy between the molecular and ionised gas rotation curves in one of our lensed galaxy which allows us to highlight the co-existence of a thin molecular gas disk and thick ionised gas disk. When combining our lensed z~1 galaxies and local analogs, we also find that the molecular gas velocity dispersion strongly correlates with the gas fraction and the star formation rate. We also obtain that the molecular gas velocity dispersion is smaller by a factor 2-3 compared to the ionised gas velocity dispersion, meaning that disk stability measurements at high redshift have been over-estimated. A low Toomre Q parameter (~0.3) do not agree with simulations and gravity-driven turbulence models which predict that galaxies self-regulate with Q~1.
Unexpected Spectral Variability of Peaked Spectrum Radio Galaxies at Low Frequencies
Creators: name: Ross, Kathryn
Publisher: name: Zenodo
Year: 2020

description: The majority of well-known radio-loud active galactic nuclei (AGN) are adorned with radio lobes that extend far beyond the core of the optical host galaxy. Despite significant advances in understanding the origins of such AGN, many questions remain about their evolutionary scenario. A subset of powerful, compact radio AGN, which can have the same morphology as the massive radio-loud AGN but on much smaller spatial scales, seem to be the key to understanding the early evolutionary stages of radio AGN. However, it is still unclear whether these compact peaked-spectrum sources, identified due to their peak in their spectra, are small due to a dense surrounding environment (frustration scenario) or are young and haven't had enough time to grow to larger scales (youth scenario). The GaLactic and Extragalactic All Sky MWA (GLEAM) survey is unparalleled in finding these sources due to incredibly wide fractional bandwidth at low frequencies, with observations from 72-231MHz. A sample of 1,483 peaked sources from GLEAM was selected by Callingham et. al (2017). We have followed these sources up a year later with the MWA and conducted a variability analysis of their spectra - making this the largest spectral variability study of its kind. Contrary to expectations, we have found 49 sources that show significant variation in flux density and spectral shape. Such variation suggests that the fundamental theories and models of the evolution of these sources is seriously lacking. Our comprehensive study of the type of variability present shows the unexpected dynamic nature of these compact sources.

description: We measure the rest-frame UV luminosity function (LF) to determine to the AGN/Galaxy fraction at z~4 self-consistently over a very wide range in absolute magnitude (MUV) of -26 to -20 that is consistent with past studies at either end. The LF is constructed with a large sample of 47,700 candidates at z~4. These are selected from a photometric redshift catalogue generated from the combined COSMOS and XMM-LSS fields with the use of deep CFHT, HSC and VISTA photometric data. We simultaneously fit for both AGN and galaxy LFs using a combination of Schechter & Double Power Law (DPL) functions alongside a single power law for the AGN slope. We find that AGN begin to contribute significantly to the LF at MUV~-23 and the transition into AGN domination at brighter magnitudes is found to be much sharper than past studies. We measure a steep AGN slope with alpha = -2.00 (-1.71) when fit alongside a Schechter function (Double Power Law) for the galaxies. A lack of evolution in the shape of the bright-end of the LBG component when compared to studies at z~5 indicate that evolution of the bright-end of the total LF is governed by the development of AGN at z~4.

description: We study the stellar population properties of massive star-forming clumps in gas-rich, turbulent disk galaxies. Massive star-forming clumps at z=1-3 are thought to play critical roles on the build-up of either bulges or thick disks. However, due to observational constraints such as, resolution and wavelength coverage the fate of clumps remains poorly understood. Of particular interest is the age and mass of clumps for two reasons: (1) the distribution of clump masses offers a constraint on feedback models, and (2) clumps are thought to contribute some mass to bulges. Our team uses a sample of galaxies, called DYNAMO, that are very similar to z~2 main sequence galaxies. DYNAMO galaxies are rare local galaxies that have similar kinematics, gas fraction and morphology to those of high z main sequence galaxies. I will show results on HST observations of DYNAMO sample from wavelengths from 225 nm to 1.2 $\mu$m. I apply stellar population models to 5-filter SED to determine the ages and masses of clumps. We provide the best possible estimates of stellar mass, as ours is the only work that can resolve massive clumps of stars in the near-IR light.
Galaxy morphology and the stellar-halo mass relation

description: We use data from the SDSS DR7 and visual classifications of morphology from the Galaxy Zoo project to show that the scatter in the stellar-halo mass relation correlates with galaxy morphology, such that more massive galaxies at fixed halo mass are mostly spirals. We obtain this same correlation in galaxies from the EAGLE simulation. We discuss the galaxy-black hole relation, halo formation time and galaxy assembly history as principal causes that plausibly explain this correlation.

description: Seven Mg(OEt)2/FeCl3/SiCl4/TiCl4 type procatalysts supported on Mg(OEt)2/FeCl3 mixtures were prepared in order to unravel effect of Fe doping on the catalytic performance in ethylene polymerization. In polymerization experiments, the catalyst based on a support containing an optimum doping amount of 10 wt.% of FeCl3, i.e. C-F10-Si, exhibited an activity 2.4 times greater than that shown by the reference catalyst, C-M. The MW and bulk density of the produced polymers were increased, while the wax amount decreased using doped catalysts. In the next step, the copolymerization of ethylene with 1-hexene was carried out using C-M as reference and C-Fe10-Si as the most efficient procatalysts. In copolymerization experiments, C-Fe10-Si exhibited much higher activity and comonomer incorporation in comparison with reference catalyst. Finally, to shed light on possible interaction of TiCl4 with doped and undoped catalysts, as well as their efficiency in ethylene polymerization, molecular simulation was performed. Energy results revealed that the doping does not alter significantly the capability of the Ti to insert ethylene monomer.
Where are the red nuggets? Massive compact spheroids across time

description: The absence of compact, quiescent massive galaxies in the local Universe is a mystery. These objects, with effective radii R_e < (2-2.5) kpc and stellar masses > (0.4-0.7) x 10^11 M ⨀, were relatively common at z~1.5. It is commonly speculated that they grew in size through minor (dry) mergers to become elliptical galaxies by z=0. We are exploring an alternative scenario in which gas accretion and minor mergers build a disk around these compact galaxies, effectively hiding them as the bulge component of today's lenticular galaxies. We are carefully measuring the sizes and masses of bulges in the local Universe and will compare their number density and mass function with the high-redshift compact massive galaxies, in turn providing constraints on the fraction of galaxies that underwent such an evolutionary pathway. This project highlights the need to go beyond treating galaxies as single-component systems.
From luminosity functions to colour distributions: tackling the next challenge in cosmological simulations

description: Galaxy spectral energy distributions (SED) remain among the most challenging and informative of the direct observables to reproduce in simulations, due to the large and complex mixture of physical processes that shape the radiation output of a galaxy. With the increasing number of surveys utilizing broadband colours as part of their target selection criteria, the production of physically-motivated realistic SED in simulations becomes necessary also for assisting in survey design. The recent successes in the reproduction of observed luminosity functions from far-ultraviolet to far-infrared represent a critical step towards better galaxy colour predictions. Here I will present that with the latest implementation of Shark, a state-of-the-art, open-source SAM, and ProSpect+Viperfish, a SED generator suite, we can closely reproduce the optical colours distributions observed in both the Galaxy And Mass Assembly (GAMA) survey and the Deep Extragalactic Visible Legacy Survey (DEVILS). I will specifically explore how the treatment of feedback, stellar formation, radiation re-processing by dust and central-satellite interactions have proven critical for this achievement.

description: Development of organic fertilizers using microbial extracts is an emerging method in organic farming. The objective of this study was to identify and characterize the bioactive substances in a plant growth-promoting bacterial culture, intended to enhance the growth of oriental melons (Cucumis melo L.). LKE15 was isolated from oriental melon rhizosphere soil and identified as Bacillus sp. LKE15 through 16S rDNA sequencing of the bacterial genomic DNA and a subsequent phylogenetic analysis. Bacillus sp. LKE15 was found to enhance the shoot length, fresh weight, dry weight, and chlorophyll content of both dwarf rice (gibberellins [GAs]-deficient mutant, waito-C) and normal rice (active GAs biosynthesis, Hwayoungbyeo) cultivars, as compared to their controls. The presence of bioactive metabolites such as GAs (GA4, GA9, and GA34), indole-3-acetic acid, and high concentrations of phosphate in the bacterial culture filtrate (CF) significantly promote host plant growth. The plant growth-stimulating effect of CF was confirmed by the increased shoot length, root length, and plant fresh weight of oriental melon as compared to the controls. Similarly, Bacillus sp. LKE15 inoculation also enhanced plant growth but at a lower rate than CF. The increased synthesis of chlorophyll and individual amino acids and their derivatives, including taurine, aspartic acid, threonine, serine, glycine, alanine, citrulline, isoleucine, leucine, tyrosine, β-alanine, γ-amino-n-butyric acid, ethanolamine, 1-methylhistidine, and hydroxyproline in CF-treated plants reflected a significant increase in the growth of treated plants, as compared to the control. However, magnesium, potassium, and phosphorus contents were significantly enhanced in plants treated with CF. Results of this study suggest that the availability of bioactive metabolites in the CF of Bacillus sp. LKE15 stimulates plant growth, and that treatment with the CF of Bacillus sp. LKE15 would be a useful tool for the organic farming of crop plants.

description: The spectre of regulatory reform carried out in a range of Western countries has generated concern amongst parts of the environmental policy community. Quality and effectiveness are said to be at stake, but empirically there is a dearth of data on the relationship between provisions for quality control and the effects on quality and effectiveness. This research addresses this lacuna by analysing the effects of different quality control provisions in the Netherlands and Denmark for a globally institutionalized environmental appraisal tool—Environmental Assessment (EA). Extensive technical provisions for quality control in the Netherlands have led to it being described as the ‘Rolls Royce’ of EA systems, while in Denmark the polity is expected to take charge of quality control. The effects of quality control are investigated through surveys and in-depth interviews with actors centrally engaged with EA implementation. The results show that quality control provisions are poorly related to the perceived quality and effectiveness of EA. Only the appropriateness of the scope of EA reports is perceived to be strongly related to quality control provisions. The findings are relevant for environmental policy communities concerned with quality control systems and effectiveness of policy appraisal tools and policy-makers contemplating regulatory reforms.
