Glomalin and Soil Aggregation under Six Management Systems in the Northern Great Plains, USA  [PDF]
Kristine A. Nichols, James Millar
Open Journal of Soil Science (OJSS) , 2013, DOI: 10.4236/ojss.2013.38043

The soil environment is linked to aboveground management including plant species composition, grazing intensity, levels of soil disturbance, residue management, and the length of time of a living plant is growing. Soil samples were collected under rangeland [native grass, rotational grazing (NGRG); tame grass, heavy grazing (TGRG); and tame grass, rotational grazing (TGHG)] and cropland [conventional till (CT); CT plus manure (CTM); and long term no till (NT)] systems. The rangeland systems were hypothesized to have higher glomalin content [measured as Bradford-reactive soil protein (BRSP)] and water stable aggregation (WSA) than the cropland systems. In addition, within both rangeland and cropland systems, BRSP and WSA were expected to decline with increased disturbance due to grazing or tillage and going from native to introduced plant species. Differences were detected for BRSP with NGRG and CTM having the highest values in range and cropland systems, respectively. However, the CTM system had higher BRSP values than one or both of the tame grass systems while the CT and NT systems had similar values. Correlation analysis showed strong relationships between all of the BRSP values and WSA.

Abstract: At the recent annual meeting on the human genome in Helsinki, organized by the Human Genome Organisation (HUGO), close to 700 scientists gathered to present and discuss the latest advances in genome research. This report presents some selected highlights.Through their effects on gene expression, polymorphisms in the human genome can contribute to phenotypic variation and disease susceptibility. For many diseases, such as cancer, great effort is being made to study the sequence variants that contribute to disease susceptibility. The impact of genetic variation on common diseases was addressed by Kari Stefansson (deCODE Genetics, Reykjavik, Iceland), who gave an update on the identified sequence variants that may increase the risk of developing type 2 diabetes, prostate cancer, myocardial infarction, stroke and schizophrenia. In the past decades, type 2 diabetes has become a major health problem in the Western world, as both its incidence and its prevalence have increased rapidly. Stefansson reported his group's recent discovery of an inherited variant of the gene TCF7L7, encoding a protein called transcription factor 7-like 2 located on chromosome 10, which is estimated to account for about 20% of the diabetes cases. They have also showed an association between a common genetic variant in the microsatellite DG8S737 at chromosome band 8q24, which may contribute to the development of prostate cancers in European and African populations.Single-nucleotide polymorphism (SNP) genotypes correlated with gene-expression data in breast tumors were presented by Vessela Kristensen (The Norwegian Radium Hospital, Oslo, Norway). For genotyping, she and her colleagues selected sets of genes involved in reactive oxygen species signaling (ROS) and the repair of DNA damage caused by ROS - that is, pathways that are generally affected by chemotherapy and radiation therapy. Using various statistical approaches, the genetic association between SNPs in genes involved in the ROS pathways a
East Greenland Caledonides: stratigraphy, structure and geochronology: Reconnaissance Pb-Pb dating of single mineral phases by the step-leaching method: results from the Caledonides of East Greenland
Thrane, Kristine
Geological Survey of Denmark and Greenland Bulletin , 2004,
Abstract: Reconnaissance Pb-Pb step-leaching analyses have been carried out on garnet and kyanite from the Krummedal supracrustal sequence in East Greenland, yielding respectively Neoproterozoic and Caledonian ages. These data support previous analyses suggesting that the Krummedalsupracrustal sequence, widespread in southern parts of the East Greenland Caledonides, was affected by both an early Neoproterozoic and a Caledonian thermal event. Titanite and apatite fractions from the underlying crystalline basement rocks were analysed in order to obtain metamorphic ages, as a contrast and supplement to the numerous existing protolith ages on orthogneisses. The titanite yielded a date of 486 ± 15 Ma which, if interpreted as a true age, is older than the usual range of Caledonian ages in East Greenland. The significance of this date is uncertain, but one possibility is that it reflects extension and subsidence taking place prior toCaledonian collision. The apatite, in contrast, yielded a very young Caledonian date of 392 ± 24 Ma that may reflect the cooling of the basement gneisses to < 500°C subsequent to collision.
East Greenland Caledonides: stratigraphy, structure and geochronology: Palaeoproterozoic age of a basement gneiss complex in the Charcot Land tectonic window, East Greenland Caledonides
Thrane, Kristine
Geological Survey of Denmark and Greenland Bulletin , 2004,
Abstract: The Charcot Land tectonic window exposes crystalline basement gneisses, which form part of the foreland of the East Greenland Caledonides. These gneisses were previously believed to beArchaean in age, on the basis of imprecise K-Ar analyses carried out in the early 1980s on hornblende from amphibolitic bands and inconclusive Rb/Sr isotope data. New U-Pb singlezircon ion microprobe analyses on the gneisses of the window yield upper intercept ages of 1916 ± 21 and 1928 ± 11 Ma, and are interpreted to represent the age of crystallisation of the igneous protolith. The foreland gneisses of the Charcot Land window are similar in age to parts of the allochthonous gneiss complexes of structurally overlying thrust sheets, but the two terranes have different lithological and structural characteristics. No Archaean rocks have been identified with certainty in any of the East Greenland Caledonian foreland windows.

Cues and economy in the acquisition of verb movement

Nordlyd : Troms? University Working Papers on Language & Linguistics / Institutt for Spr?k og Litteratur, Universitetet i Troms? , 2004,
Abstract: In this paper we will discuss how economy principles interact with cues in the input in bilingual first language acquisition. We will look at the acquisition of verb placement in a child acquiring English and Norwegian simultaneously. Based on data from this child, it will be argued that when faced with ambiguous cues with respect to the verb movement parameter, children do not necessarily adopt the default, less marked setting. Rather, they may opt for a setting which yields an overall consistent grammar, even when this grammar contains operations that are more costly than those used in the target language. We will suggest that economy in acquisition may involve consistency in a grammar in correlation with economy in the more traditional sense within minimalism, where moving an element in general is considered more costly than not moving it (Chomsky 1995).
The degree of verb movement in embedded clauses in three varieties of Norwegian
Kristine Bentzen
Nordlyd : Troms? University Working Papers on Language & Linguistics / Institutt for Spr?k og Litteratur, Universitetet i Troms? , 2007,
Abstract: The position of the verb(s) in embedded non-V2 contexts varies in Norwegian dialects. In Eastern Norwegian (EastN), all verbs have to follow all adverbs in non-V2 contexts. In Troms Northern Norwegian (TrNN) main verbs and non-finite auxiliaries have to follow all adverbs, but finite auxiliaries may precede adverbs they take scope over. In Regional Northern Norwegian (ReNN) all finite verbs (main/auxiliary) may precede all adverbs, and non-finite auxiliaries may precede adverbs they take scope over. These data are accounted for within a remnant movement approach. The variation between the three dialects is argued to follow from differences in how selectional features on auxiliaries and T are checked. It is suggested that auxiliaries are associated with a pair of functional projections (so-called lifters): a VP lifter below and an AdvP lifter above. An auxiliary with these lifters ‘sinks’ below adverbs it takes scope over. Overt feature checking (through adjacency) occurs when the lifters are present; covert feature checking occurs when the lifters are absent. In EastN, overt feature checking, and the lifters, is obligatory for all auxiliaries; in TrNN this is obligatory for non-finite auxiliaries but optional for finite auxiliaries; in ReNN this is optional for all auxiliaries.
V-to-I Movement in the Absence of Morphological Cues:Evidence from Adult and Child Northern Norwegian
Kristine Bentzen
Nordlyd : Troms? University Working Papers on Language & Linguistics / Institutt for Spr?k og Litteratur, Universitetet i Troms? , 2003,
Abstract: Several people have pointed out that there seems to be a close correlation between inflectional morphology and verb movement (see e.g. Kosmeijer 1986, Holmberg & Platzack 1988). The nature of this correlation has been claimed to go in both directions. Vikner (1994, 1995) and Rohrbacher (1999) have both suggested that the verb can only move to an inflectional head if the morphology is rich enough. Bobaljik (1995), Thráinsson (1996), and Bobaljik & Thráinsson (1998), on the other hand, argue that the correlation goes in the other direction, i.e. that rich inflection is a reflection of verb movement, rather than the cause for it. A correlation between morphology and verb movement has also been suggested in first language acquisition (Santelmann 1995 on Swedish, Clahsen et al. 1996 on German, Déprez & Pierce 1993, and Meisel 1994 on French). Several of these studies indicate that children use inflectional morphology as a cue for verb movement in the acquisition process, and that they employ verb movement as soon as they acquire verbal inflection. In this paper I will present new data from a dialect of Northern Norwegian which challenge the strong correlation between verb movement and inflectional morphology in both the adult language and in the acquisition of this dialect. More specifically, this dialect appears to have optional independent V-to-I movement despite the fact that the inflectional morphology is very poor. With respect to the acquisition of this dialect, preliminary data from one subject seem to indicate that children to some extent overgeneralise this verb movement pattern into constructions where adult speakers would not allow it.
m-Learning: Positioning educators for a mobile, connected future
Kristine Peters
International Review of Research in Open and Distance Learning , 2007,
Abstract: Mobile learning is variously viewed as a fad, a threat, and an answer to the learning needs of time-poor mobile workers, so does it have a place in delivering mainstream learning? Based on a 2005 comparative research project, commissioned by the Australian Flexible Learning Framework, the paper reports on research into Web-based information about the use of mobile technologies for commerce and learning, which was then tested through 29 interviews with manufacturers of mobile devices, businesses and education providers. The research found that mobile technologies were in common use in some commercial sectors, but their use purely for learning was rare. m-Learning lends itself to new methods of delivery, however, that are highly suited to the ‘just enough, just in time, and just for me’ demands of 21st Century learners.
Trials and Tribulations: Psychopathic Traits, Emotion, and Decision-Making in an Ambiguous Case of Sexual Assault  [PDF]

Judgments of criminal culpability often are influenced by factors unrelated to case content, such as the emotionality of the victim and the personality of the judge. In the current study, we investigated the relationship between psychopathic traits (high/low) and information processing modes (experiential vs. rational) in a group of mock jurors (N = 383) asked to judge a “he said, she said” ambiguous case of sexual assault that varied according to both victim and defendant emotionality (high/low). The results demonstrated that victim and defendant emotionality was critical in determining case outcomes, which interacted with the processing style that participants utilized more. Specifically, experiential processors were more punitive towards the defendant when the defendant displayed low levels of emotion relative to high emotionality, whereas rational processors were slightly more punitive when high levels of emotion were being displayed. Psychopathic traits had no influence on ratings of veracity/credibility of the victim and defendant, or on overall guilt determinations and severity of sentencing. However, participants high in psychopathic traits believed that the alleged victim was making a false allegation more often when she was less emotional, and they were less punitive towards the false allegation than individuals low in psychopathic traits. These findings have important implications concerning how cases of sexual assault are interpreted in court, and extra-legal factors that may alter case outcomes.
