Fixing Language: ‘People-First’ Language, Taxonomical Prescriptivism, and the Linguistic Location of Disability
Angelo Muredda
The English Languages : History, Diaspora, Culture , 2012,
Abstract: This paper explores a range of perspectives on people-first language, considering how the taxonomical prescriptivism in policy since the early 1990s locates disability as a detachable part of an individual. I attend both to some activists’ championing of this linguistic turn for its recognition of personhood outside impairment and to the charge within disability studies that it restricts the conceptual domain of disability to physical impairment. Moreover, I examine how people-first language is both the product of prescriptive policy documents as well as a contributing factor in future policy – determining, for instance, whether disability initiatives are intended to focus on physical rehabilitation or improved accessibility. Lastly, I turn to recent work in sociolinguistics on political correctness and people-first language, positioning it against various approaches to the ethical valence of such linguistic modifications, and their potential to remake social realities. My purpose in tracing the status of people-first language in this multitude of discursive venues is to consider the extent to which it determines how disability is conceptualized and consequently realized in more practical settings.
Evaluating National Socialism as a “True” Fascist Movement  [PDF]
Angelo Nicolaides
Advances in Historical Studies (AHS) , 2013, DOI: 10.4236/ahs.2013.21004
Abstract: The terms “Fascism” and “Nazism” are often linked, and at times they are regarded as one and the same ideology. The question raised is what is the distinction between Fascism and National Socialism or Nazism? A closer look at the ideas of fascism and National Socialism reveals certain affinities and overlaps with other ideologies, like Socialism, Liberalism and Conservatism. Fascism had many contradictory strands and despite deep unresolved tensions between ideas of race, nation and state in both National Socialism and fascism, the former is regarded as a “true” fascist movement. This article strives to ascertain the main differences and similarities between National Socialism and fascism and to ascertain if National Socialism could be considered to be a “true” fascist movement.
A Review of Carbonatite Occurrences in Italy and Evaluation of Origins  [PDF]
Angelo Paone
Open Journal of Geology (OJG) , 2013, DOI: 10.4236/ojg.2013.32011
Abstract:

This review and evaluation seeks to clarify the controversial origins of the Umbria-Latium Ultra-alkaline District (ULUD) and the Vulture carbonatitic occurrence (Intramontane Ultra-alkaline Province, IUP) and their relation to the Roman Comagmatic Province (RCP). Generally, the geochemical and isotopic features of the IUP can be linked to those of the RCP. Hence, the rocks of the ULUD district, together with part of the Tuscan and Roman Province generated in the last 2 Ma can be ascribed to a complex interplay of two subduction events related to magmatism associated with the European and Adria slabs associated with the effect of a slab window below the Italian Peninsular. Carbonate sediments together with pelagic-terrigenous sediment played a major role in the metasomatism of the mantle wedge beneath the IUP, and perhaps all along the transect from southern Italy (Eolian Islands magmatism) to north-central Italy (Tuscan and Umbria magmatism). A diffuse CO2 + H2O metasomatic front produced the condition necessary for the formation of carbonatitic magmatism. However, even where carbonatites are related to continental rift system (i.e., OIB), an origin for MORB-sediment convective recycling melting in the mantle has been hypothesized [i.e., 1].

The Use of Plants and Wildflowers as Bioremediation for Contaminated Soils in the Hong Kong S.A.R.  [PDF]
Angelo Indelicato
Open Journal of Soil Science (OJSS) , 2014, DOI: 10.4236/ojss.2014.49032
Abstract: Heavy metal contamination of the biosphere has increased sharply over the last century. Anthropogenic activities such as industrialisation and demographic growth can be considered as the main causes of it. Soil contamination affects every organism and poses major environmental and human health problems worldwide. The issue has been addressed in the past and a few methodologies have been developed in order to effectively clean up the contaminated areas. However, many of these remedies are very aggressive and can damage the soil. This paper focuses on the use of gentler techniques, which take advantage of the properties of several plants and wildflowers that absorb heavy metals and polycyclic aromatic hydrocarbons, and their potential application in megacities such as Hong Kong.
Pb Isotopes Data from the Campanian Volcanic Province: A Model to Generate These Distinctive Pb Isotopic Variations  [PDF]
Angelo Paone
Open Journal of Geology (OJG) , 2015, DOI: 10.4236/ojg.2015.51001
Abstract: A broad set of samples from the CVP has been analyzing Pb isotopes. Campanian Volcanic Province (CVP) has been produced by various ranges of mixing between three components: 1) MORB, 2) Hercynian basement and 3) upper crust. Anyhow, the upper crust that has modified the Pb isotopic composition also shows trends towards an Achaean upper crust. This is consistent for all Mediterranean area. This is not in contrast with the past plate tectonic reconstruction. Also the surface sediments (GLOSS) may have been a mixing between the Achaean upper crust and a Hercynian component with an implication worldwide due to the rock cycle processes.
Volatiles (S-CO2-H2O-Cl-F) Behavior during the AD 1944 Eruption  [PDF]
Angelo Paone
International Journal of Geosciences (IJG) , 2015, DOI: 10.4236/ijg.2015.63017
Abstract: The AD 1944 is the last vulcanian-effusive eruption of Vesuvius volcano. I have reviewed most of the major and volatile elements in order to better understand the eruptive dynamic of this hazardous volcano. These volcanic products were basically formed by at least two main petrogenetic mechanisms: 1) mixing, 2) crystal fractionation. Crystal fractionation plays a major role in the evolution of the volcanic products of the AD 1944 eruption. According to the major elements data, several fractionation lines can be employed. Volatile data are analyzed in sequence. Indeed, the volatile data allow an insight into the exsolution and degassing processes occur during the growth and eruption of the AD 1944 eruption. Some inferences are also made on the exsolution and degassing depth. The volatile data illustrate a sequential order of exsolution for the AD 1944 eruption: Cl-H2O-CO2-S and finally as volatile phase degassed fluorine. The eruption has not interacted with external water. An early exsolution of Cl in Cl-rich magmas is also confirmed by experimental and geological studies (3 - 4 Kbars) coinciding with the deep magma reservoir.
MADS Box Transcript Amount is Affected by Ethylene during Abscission  [PDF]
Valeriano Dal Cin, Angelo Ramina
American Journal of Plant Sciences (AJPS) , 2011, DOI: 10.4236/ajps.2011.23035
Abstract: Thinning of young fruit is an important agronomical practice to ensure the maximum economic production. This practice is based on the control of the natural self thinning process occurring during fruit development. At the early stages of fruit development (fruitlet), the vegetative part of the tree is competing with the reproductive part of the tree and within the fruit clusters the different fruitlets are competing with each other. As a result the least fit organ abscises, Ethylene and auxin play a central role in this event but the role of ethylene is not thoroughly understood because in other systems abscission occurs partly with ethylene independent processes. We have followed the early development of fruitlets and studied the transcription patterns of MADS-box and ethylene related transcripts. Furthermore, we verified that ethylene has an effect on the expression of some ethylene related and MADS BOX genes. We propose that the ethylene burst during abscission induction is similar to a stage 2 ethylene system and it is related to fruitlet growth by affecting transcript amount of MADS-BOXes which modulate seed development and cortex growth.
Livestock Antibiotic Effects on Nitrification, Denitrification, and Microbial Community Composition in Soils  [PDF]
Sagarika Banerjee, Elisa D’Angelo
Open Journal of Soil Science (OJSS) , 2013, DOI: 10.4236/ojss.2013.35024
Abstract:

The broiler (Gallus gallus domesticus) industry in the United States and several other countries routinely includes subtherapeutic levels of antibiotics such as roxarsone, virginiamycin, and bacitracin in the feed to improve bird growth yields. Large fractions of the antibiotics fed to the birds are excreted in manure (litter), which is often applied to soils to improve fertility. Some concerns with this practice are antibiotic-induced alterations in microbially-mediated nutrient cycling, which could influence plant productivity and environmental quality. To investigate this possibility, a series of lab experiments were conducted to determine the effects of increasing levels of the three livestock antibiotics on nitrification, denitrification, and microbial community composition (fatty acid methyl ester profiles) of soils collected along a catena. Roxarsone and virginiamycin significantly influenced microbial community composition and inhibited nitrification in the soils, but only at levels that were several-fold higher than expected in poultry litter-applied soils. Bacitracin did not affect microbial growth, microbial community composition, or nitrification at any concentration tested (up to 500 mg·kg-1). None of the antibiotics influenced denitrification at environmentally-relevant concentrations. Amounts of antibiotics in soil solution were greatly reduced by sorption, which followed Freundlich models in the concentration range of 1 - 500 mg·L-1. Results from this study indicated that addition of roxarsone, virginiamycin, or bacitracin to these soils at environmentally-relevant concentrations would not likely impact microbial community composition, nitrification or denitrification due to intrinsic resistance/insensitivity of microorganisms to these antibiotics and reductions in the bioavailable amounts due to sorption by soil surfaces.

Non-Linear Semi-Quantum Hamiltonians and Its Associated Lie Algebras  [PDF]
Claudia M. Sarris, Angelo Plastino
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.520306
Abstract: We show that the non-linear semi-quantum Hamiltonians which may be expressed as\"\"(where\"\"is the set of generators of some Lie algebra and are the classical conjugated canonical variables) always close a partial semi Lie algebra under commutation and\"\", because of this, it is always possible to integrate the mean values of the quantum degrees of freedom of the semi-quantum non-linear system in the fashion:\"\"(where\"\"is the Maximum Entropy Principle density operator) and, so, these kind of Hamiltonians always have associated dynamic invariants which are expressed in terms of the quantum degrees of freedom’s mean values. Those invariants are useful to characterize the kind of dynamics (regular or irregular) the system displays given that they can be fixed by means of the initial conditions imposed on the semi-quantum non-linear system.
A MultiScale Gibbs-Helmholtz Constrained Cubic Equation of State
Angelo Lucia
Journal of Thermodynamics , 2010, DOI: 10.1155/2010/238365
Abstract: This paper presents a radically new approach to cubic equations of state (EOS) in which the Gibbs-Helmholtz equation is used to constrain the attraction or energy parameter, a. The resulting expressions for (,) for pure components and (,,) for mixtures contain internal energy departure functions and completely avoid the need to use empirical expressions like the Soave alpha function. Our approach also provides a novel and thermodynamically rigorous mixing rule for (,,). When the internal energy departure function is computed using Monte Carlo or molecular dynamics simulations as a function of current bulk phase conditions, the resulting EOS is a multiscale equation of state. The proposed new Gibbs-Helmholtz constrained (GHC) cubic equation of state is used to predict liquid densities at high pressure and validated using experimental data from literature. Numerical results clearly show that the GHC EOS provides fast and accurate computation of liquid densities at high pressure, which are needed in the determination of gas hydrate equilibria.
