Cold war theology: a controversial religious image of King James VI & I in England and on the Continent in 1603
No full textA former student of James Cameron’s, Ian Hazlett contributes a paper very much in the spirit of his teacher. It considers the afterlife of the King’s (or Negative) Confession, commissioned by James VI of Scotland in 1581 as a clear statement of his Calvinist credentials. By the time he gained the crown of England in 1603 however, his evolving religious views meant it had become a document he sought to distance himself from. Both Protestant and Catholic propagandists and publishers, keen to give a particular picture of the theological sympathies of the new English king, subsequently produced a surprisingly varied selection of versions of the Confession. These sources and what they can tell us about the theology and politics of the day are considered here for the first time in a scholarly study.Publisher PD
Iwasawa theory for modular forms at supersingular primes
No full textLet f=\sum a_nq^n be a normalised eigen-newform of weight k\ge2 and p an odd prime which does not divide the level of f. We study a reformulation of Kato's main conjecture for f over the Zp-cyclotomic extension of Q. In particular, we generalise Kobayashi's main conjecture on p-supersingular elliptic curves over Q with a_p=0, which asserts that Pollack's p-adic L-functions generate the characteristic ideals of some \pm-Selmer groups which are cotorsion over the Iwasawa algebra \Lambda=Zp[[Zp]].
We begin by studying the p-adic Hodge theory for the p-adic representation associated to f in the case when a_p=0. It allows us to give analogous definitions of Kobayashi's \pm-Coleman maps and \pm-Selmer groups. The Coleman maps are used to show that the Pontryagin duals of these new Selmer groups are torsion over \Lambda as in the elliptic curve case. As a consequence, we formulate a main conjecture stating that Pollack's p-adic L-functions generate their characteristic ideals. Similar to Kobayashi's works, we prove one inclusion of the main conjecture using an Euler system constructed by Kato.
We then prove the other inclusion of the main conjecture for CM modular forms, generalising works of Pollack and Rubin on CM elliptic curves. As a key step of the proof, we generalise the reciprocity law of Coates-Wiles and Rubin.
Next, we study Wach modules associated to positive crystalline p-adic representations in general and generalise the construction of the Coleman maps. By applying this to modular forms with much more general a_p, we define two Coleman maps and decompose the classical p-adic L functions of f into linear combinations of two power series of bounded coefficients generalising works of Pollack (in the case a_p=0) and Sprung (when f corresponds to an elliptic curve over Q with a_p\ne0). Once again, this leads to a reformulation of Kato's main conjecture involving cotorsion Selmer groups and p-adic L-functions of bounded coefficients. One inclusion of this new main conjecture is proved in the same way as the a_p=0 case.
Finally, we explain how the \pm-Coleman maps can be extended to Lubin-Tate extensions of height 1 in place of the Zp-cyclotomic extension. This generalises works of Iovita and Pollack for elliptic curves over Q
A HOUSEHOLD PRODUCTION ANALYSIS OF FUELWOOD DEMAND IN RHODE ISLAND
No full textA model analyzing household substitution of fuelwood for other heating fuels is needed to clarify the relationship between energy prices and patterns of forest resource utilization. This paper employs the household production methodology to model fuelwood demand in Rhode Island. Data from a cross-sectional survey of 515 households are employed to test a discrete-choice model of household participation in wood-burning and a four-equation system modeling household production of heat and aesthetic benefits from fuelwood and stove capital. Control of selection bias via inclusion of an appropriate instrument allows analysis of aggregate demands. Some broad policy prescriptions applicable to the Northeast generally are presented.Resource /Energy Economics and Policy,

URI Disambiguation in the Context of Linked Data
No full textThe Linked Data initiative has given rise to an increasing number of RDF datasets, many of which are freely accessible online. These resources often arise as a result of database exports; however sufficient consideration may not be given to the unseen implications caused when they are used in the wider context of the Semantic Web. This paper investigates two popular resources, DBLP and DBpedia, and discusses whether the issues regarding identity management and co-reference resolution have been suitably addressed. We find that a large percentage of authors in DBLP have been conflated, and that disambiguation pages have been incorrectly linked using owl:sameAs within DBpedia. Systems for dealing with these issues are presented, and directions are given for future research
Wach modules and Iwasawa theory for modular forms
No full textWe define a family of Coleman maps for positive crystalline p-adic representations of the absolute Galois group of Qp using the theory of Wach modules. Let f be a normalized new eigenform and p an odd prime at which f is either good ordinary or supersingular. By applying our theory to the p-adic representation associated to f, we define Coleman maps Col_i for i = 1, 2 with values in Qp ⊗Zp Λ, where
Λ is the Iwasawa algebra of Zp× . Applying these maps to the Kato zeta elements gives a decomposition of the (generally unbounded) p-adic L-functions of f into linear combinations of two power series of bounded coefficients, generalizing works of Pollack (in the case ap = 0) and Sprung (when f corresponds to a supersingular elliptic curve). Using ideas of Kobayashi for elliptic curves which are supersingular at p, we associate to each of these power series a Λ-cotorsion Selmer group. This allows us to formulate a "main conjecture". Under some technical conditions, we prove one inclusion of the "main conjecture" and show that the reverse inclusion is equivalent to Kato’s main conjecture
Open access self-archiving: An author study
No full textThis, our second author international, cross-disciplinary study on open access had 1296 respondents. Its focus was on self-archiving. Almost half (49%) of the respondent population have self-archived at least one article during the last three years. Use of institutional repositories for this purpose has doubled and usage has increased by almost 60% for subject-based repositories. Self-archiving activity is greatest amongst those who publish the largest number of papers. There is still a substantial proportion of authors unaware of the possibility of providing open access to their work by self-archiving. Of the authors who have not yet self-archived any articles, 71% remain unaware of the option. With 49% of the author population having self-archived in some way, this means that 36% of the total author population (71% of the remaining 51%), has not yet been appraised of this way of providing open access. Authors have frequently expressed reluctance to self-archive because of the perceived time required and possible technical difficulties in carrying out this activity, yet findings here show that only 20% of authors found some degree of difficulty with the first act of depositing an article in a repository, and that this dropped to 9% for subsequent deposits. Another author worry is about infringing agreed copyright agreements with publishers, yet only 10% of authors currently know of the SHERPA/RoMEO list of publisher permissions policies with respect to self-archiving, where clear guidance as to what a publisher permits is provided. Where it is not known if permission is required, however, authors are not seeking it and are self-archiving without it. Communicating their results to peers remains the primary reason for scholars publishing their work; in other words,
researchers publish to have an impact on their field. The vast majority of authors (81%) would willingly comply with a mandate from their employer or research funder to deposit copies of their articles in an institutional or subject-based repository. A further 13% would comply reluctantly; 5% would not comply with such a mandate
The impact of a child's death; An Interpretative Phenomenological Analysis undertaken with five head teachers
No full textAbstract
This research explores with five head teachers their views and experiences of a period when a child was terminally ill and subsequently died when in their school community.
The participants were selected purposively from Derbyshire head teachers who had experienced the death of a pupil in their school community. After interviewing the participants using a semi-structured interview schedule the transcribed interviews provided the data for the research.
The interviews were analysed, using the methodology of Interpretative Phenomenological Analysis, to explore the experiences of each of the participants. Three superordinate themes were identified which were;
Emotions and their management
Interactions with the bereaved family
Interaction with the school community
Additionally, an overarching theme of Elevation was identified.
Each theme is presented and illustrated with abstracts taken from the original data. This is accompanied by interpretation which is also discussed and compared with knowledge from the existing literature.
The research has illustrated the complications that exist for head teachers in managing their emotions and the possibility of these emotions intruding on their personal and family life. It has illustrated the way in which the relationship between the head teacher and the bereaved family changes and how it changes their interactions within the school community.
This research led to the consideration of the influence of the cultural expectation enshrined in the saying, 'De mortuis nil nisi bonum dicendum est' (Of the dead, nothing unless good). Also considered is the behavioural derivative of this saying and how it shapes the responses that head teachers make when managing a school community when a child has died. It also led to the consideration of the implications of the research findings for any support professionals who help schools
Abstract 3940: Transformation by ENO1 highlights the positive relationship between HIF1A's and VEGFA's RNA expression levels, putatively by counteracting heterogeneity in glioblastomas
No full textAbstract
Analysis of metabolic gene expression is compromised by tumor heterogeneity. Therefore, we investigated the use of RNA expression levels from ENO1, which encodes enolase 1, to adjust for glycolytic heterogeneity within glioblastomas attributed to irregular vascularity, necrosis, surgical removal, etc. Recently, this approach revealed relationships between carbonic anhydrases and amplified oncogenes (Beckner, et al. BBA Clinical 5 (2016):1-15). Here in frozen tissue samples from 22 glioblastomas, expressions of the metabolic gene encoding hypoxia inducible factor - 1A (HIF1A) and its target, vascular endothelial growth factor A (encoded by VEGFA), were contrasted with two non-metabolic genes, i.e. those encoding platelet derived growth factor A (PDGFA) and epidermal growth factor (EGF) using RT-qPCR analysis. Genes of interest (GOI) were initially normalized with delta-delta crossing threshold methodology using housekeeping genes, ACTB and GAPDH. Then, concurrent expressions of ENO1 (ave 0.83 +/- 0.18 CI (95%), range of 0.22 - 1.97 times normal) were used to mathematically transform expressions of GOI to multiples of ENO1 to putatively correct for glycolytic variation. Expressions of PDGFA (ave 1.90 +/- 0.69 CI (95%), 0.17 - 4.01 times normal) and EGF (ave 1.25 +/- 0.57 CI (95%), 0.07 - 5.14 times normal), had correlations, r = 0.65 and 0.66, unranked (Pearson's) and ranked (Spearman's) data, respectively, among the 22 tumors. After ENO1 transformation, r = 0.68 for their unranked data & the difference in their ranges rose to 1.31-fold. Prior to ENO1 transformation, expressions of HIF1A (ave 1.33 +/- 0.28 CI (95%), 0.25 - 2.55 times normal) and VEGFA (ave 2.89 +/- 1.36 CI (95%), 0.17 - 9.94 times normal) had negative correlations, r = - 0.15 and - 0.09, unranked and ranked data, respectively. However, after transforming HIF1A and VEGFA expressions to multiples of concurrent ENO1 expression, their correlation became positive in both unranked and ranked data, with r = 0.30 for the ranked (Spearman) data. The difference in the ranges of the two metabolic genes expanded to 6.76-fold. Whereas the Wilcoxon Rank Sum of VEGFA's untransformed values, with versus without 2.02-fold elevations of HIF1A expression, was insignificant, p = 0.704, using ENO1 transformed values indicated a significant relationship, p = 0.042. Therefore, ENO1 transformation revealed the anticipated relationship between HIF1A and its target, VEGFA, at the RNA expression level that was not initially apparent in this small group of tumors. Transformation via expression levels of ENO1 compensates for glycolytic heterogeneity to reveal and highlight relationships among metabolic genes when analyzing resected tumors.
