(Tables 2-7) Soil characteristics and geochemistry of marshland in the North Frisian mainland, Schleswig-Holstein, Germany

Results from a large scale soil mapping on the North Frisian mainland indicate, that field characteristics, particularly the grain-size, bedding, and degree of compaction, with in general determine the soil units mapped, are closely correlated with each other and with other field and laboratory data. Exchangable ions and the Ca/Mg-ratio, however, indicate no explainable connections with the soil units and with most of the other field characteristics but are determined postsedimentarily by processes of the development of soil and landscape, such as desalting and decalcification, silicate weathering, fresh- and salt-water innundations, salty precipitations, salty groundwater and fertilization. Therefore the Ca/Mg-ratio is not suitable to differentiate between more clayey compacted Knick-marsh soils and less clayey permeable Klei-marsh soils. The results confirm that marsh-soils may only be classified and mapped by means of all available field-data which have to be supplemented by laboratory investigations.

Paleoecology, Diagenesis and Biological Affinity of Tetradiids in the Upper Ordovician (Sandbian) Black River Group of the Kingston Area, Ontario, Canada

Tetradiids are a group of colonial, tubular fossils that occur globally in Middle to Upper Ordovician strata. Tetradiids were first described as a type of tabulate coral; however, based on their four-fold symmetry, division, and presence of a central-sparry canal, they were recently reinterpreted as a florideophyte rhodophyte algae, a reinterpretation that is tested in this thesis. This study focused on understanding the affinity and taphonomy of this order of fossil. Research was conducted by stratigraphic and petrographic analyses of the Black River Group in the Kingston, Ontario region. Tetradiid occurrences were divided into fragment or colonial, with three morphologies of tetradiids described (Tetradium, Phytopsis and Paratetradium). Morphology is specific to depositional environment, with compact Tetradium consistently within ooid grainstones and open branching Phytopsis and chained Paratetradium consistently within mudstones. Two types of patch reefs were recognized: a Paratetradium bioherm, and a Paratetradium, Phytopsis, stromatolite bioherm. The presence of bioherms implies that tetradiids were capable of hypercalcifying. Preservation styles of tetradiids were investigated, and were compared to brachiopods, echinoderms, mollusks, and ooids. Tetradiids were preferentially preserved as molds and demonstrated complete dissolution of skeletal material. Rare specimens, however, demonstrated preserved horizontal partitions, central plates, and a double wall. Skeletal molds were filled with either calcite spar, mud or encrusted by a cryptomicrobial colony. Both calcitic and aragonitic ooids were discovered. The co-occurrence of aragonitic ooids, aragonitic crytodontids, and the evolution of aragonitic, hypercalcifying tetradiids is interpreted as representing the geochemical favoring of aragonite and HMC in a time of global calcite seas. The geochemical favoring of aragonite is interpreted to be independent to global Mg: Ca ratios, but was the result of increased saturation levels and temperature driven by high atmospheric pCO2. Based on the presence of epitheca, tabulae, septa, and the commonality of growth forms, tetradiids are interpreted as an order of Cnidaria. The evolution of an aragonitic skeleton in tetradiids is interpreted to be the result of de novo acquisition of a skeleton from an unmineralized clade.

Between Principle and Practicality: A Dynamic Realist Examination of Independence in the Canadian Justice System

This work examines independence in the Canadian justice system using an approach adapted from new legal realist scholarship called ‘dynamic realism’. This approach proposes that issues in law must be considered in relation to their recursive and simultaneous development with historic, social and political events. Such events describe ‘law in action’ and more holistically demonstrate principles like independence, rule of law and access to justice. My dynamic realist analysis of independence in the justice system employs a range methodological tools and approaches from the social sciences, including: historical and historiographical study; public administrative; policy and institutional analysis; an empirical component; as well as constitutional, statutory interpretation and jurisprudential analysis. In my view, principles like independence represent aspirational ideals in law which can be better understood by examining how they manifest in legal culture and in the legal system. This examination focuses on the principle and practice of independence for both lawyers and judges in the justice system, but highlights the independence of the Bar. It considers the inter-relation between lawyer independence and the ongoing refinement of judicial independence in Canadian law. It also considers both independence of the Bar and the Judiciary in the context of the administration of justice, and practically illustrates the interaction between these principles through a case study of a specific aspect of the court system. This work also focuses on recent developments in the principle of Bar independence and its relation to an emerging school of professionalism scholarship in Canada. The work concludes by describing the principle of independence as both conditional and dynamic, but rooted in a unitary concept for both lawyers and judges. In short, independence can be defined as impartiality, neutrality and autonomy of legal decision-makers in the justice system to apply, protect and improve the law for what has become its primary normative purpose: facilitating access to justice. While both independence of the Bar and the Judiciary are required to support access to independent courts, some recent developments suggest the practical interactions between independence and access need to be the subject of further research, to better account for both the principles and the practicalities of the Canadian justice system.

Investigation of the chemical origin and evidential value of differences in the SERS spectra of blue gel inks

Highly swellable polymer films doped with Ag nanoparticle aggregates (poly-SERS films) have been used to record very high signal:noise ratio, reproducible surface-enhanced (resonance) Raman (SER(R)S) spectra of in situ dried ink lines and their constituent dyes using both 633 and 785 nm excitation. These allowed the chemical origins of differences in the SERRS spectra of different inks to be determined. Initial investigation of pure samples of the 10 most common blue dyes showed that the dyes which had very similar chemical structures such as Patent Blue V and Patent Blue VF (which differ only by a single OH group) gave SERRS spectra in which the only indications that the dye structure had been changed were small differences in peak positions or relative intensities of the bands. SERRS studies of 13 gel pen inks were consistent with this observation. In some cases inks from different types of pens could be distinguished even though they were dominated by a single dye such as Victoria Blue B (Zebra Surari) or Victoria Blue BO (Pilot Acroball) because their predominant dye did not appear in other inks. Conversely, identical spectra were also recorded from different types of pens (Pilot G7, Zebra Z-grip) because they all had the same dominant Brilliant Blue G dye. Finally, some of the inks contained mixtures of dyes which could be separated by TLC and removed from the plate before being analysed with the same poly-SERS films. For example, the Pentel EnerGel ink pen was found to give TLC spots corresponding to Erioglaucine and Brilliant Blue G. Overall, this study has shown that the spectral differences between different inks which are based on chemically similar, but nonetheless distinct dyes, are extremely small, so very close matches between SERRS spectra are required for confident identification. Poly-SERS substrates can routinely provide the very stringent reproducibility and sensitivity levels required. This, coupled with the awareness of the reasons underlying the observed differences between similarly coloured inks allows a more confident assessment of the evidential value of inks SERS and should underpin adoption of this approach as a routine method for the forensic examination of inks.

Cross-border Movement of Patients in the EU: A Re-Appraisal

The national welfare state, so it seems, has come under attack by European integration. This article focuses on one facet of the welfare state, that is, health care and on one specific dimension, that is, cross-border movement of patients. The institution which has played a pivotal role in the development of the framework regulating the migration of patients is the European Court of Justice (ECJ). The Court’s activity in this sensitive area has not remained without critics. This was even more so since the Court invoked Treaty (primary) law which not only has made it difficult to overturn case law but also has left the legislator with very little room for manoeuvre in relation to any future (secondary) EU law. What is therefore of special interest in terms of legitimacy is the legal reasoning by which the Court has made its contribution to the development of this framework. This article is a re-appraisal of the legal development in this field.

Usefulness of ultrasounds in the management of breast phyllodes tumors

Introduction. Breast phyllodes tumors (PT) are uncommon fibroepithelial lesions having potential malignant features. These tumors have characteristic features, like phleomorphism, mitoses and overgrowth of the stroma with possible infiltrative margins. The clinical behaviour could be unpredictable, since the relatively high recurrence rate despite correct surgical strategy. Conventional diagnostic examinations show high sensitivity and specificity, but cannot demonstrate the differences between benign and malignant PT. MRI is not more effective. Patients and methods. Sixteen patients affected by PT have been surgically treated at our Institution. All patients received mammography and ultrasonography (US) as preoperative diagnostic work-up. Results. in 13 patients, US was effective in preoperative diagnosis of PT. Mammography was uneffective in detecting breast lesions in 5 cases, while in 11 cases mammographic findings presented benign features, with a round opacity with moderate tissue density and well-defined wall. Conclusion. US remains the most useful diagnostic test in detecting PT. However, there is no test effective in identifying malignat PT. In case of suspicion, fine needle biopsy should be performed.

This battle was not over: Parade’s End as a transitional text in the development of ‘disenchanted’ First World War literature.

This chapter argues that the novels of Ford's Parade's End tetralogy occupy a significant place in the development of "disenchanted" fiction about the First World War. The values of Ernest Raymond's patriotic Tell England are contrasted with those of C. E Montague's Disenchantment, providing a brief synopsis of the early 1920s response to the conflict. Parade's End is seen as introducing several key themes in to the post-First World War discursive field, including national identity, psychology, memory, and time. The presentation of these aligned with the formal aspects of the novel, allows it to push the boundaries of the readerly horizon of expectations. Frayn argues that Ford's readership, though moderately-sized, was influential from a literary point of view, and thus facilitated the reception of later, more vitriolic, criticisms of war.

Investigation of the roles of CheD in the Bacillus subtilis chemotactic signal transduction

Abstract The two-component based chemotaxis signal transduction system allows flagellated bacteria to sense their surrounding chemical environment and move towards more favorable conditions. The attractant signals can be sensed by transmembrane chemoreceptors, and then transmitted to the histidine kinase CheA. Once activated, CheA interacts with the response regulator CheY through phosphorelay, which causes a change in the rotation of the flagella. The direction of flagella rotation determines whether a cell swims straight or just tumbles. Cells also need adaptation to respond to a change in chemical concentrations, and return to their prestimulated level. Adaptation in the B. subtilis chemotaxis system is achieved by three coordinated systems: the methylation system, the CheC/CheD/CheY-p system and the CheV system. CheD, the previously identified receptor deamidase, was shown to be critical to the ability of B. subtilis to perform chemotaxis and is the main focus of this study. This study started from characterization of the enzymatic mechanism of CheD. Results showed that CheD deamidase uses a cysteine hydrolase mechanism. The catalytic triad consisting of Cys33-His50-Thr27, and Ser27 is essential for receptor recognition and binding. In addition, in this study CheC was found to inhibit CheD’s deamidase activity. Through mutant screening, Phe102 on CheD was found to be the essential site to interact with CheC. Furthermore, the CheD/CheC interaction is necessary for the robust chemotaxis in vivo as demonstrated by the cheD (F102E) mutant, which lacks the ability to swim on swarm plates. Despite its deamidase activity, we hypothesized that CheD’s main role is its involvement in the CheD-CheC-CheY-p negative feedback pathway during adaptation. In particular, CheD is likely to help stabilize the transient kinase-activating state through binding to receptors. When CheY-p level is increased, CheC-CheY-p complex may attract CheD away from receptors. In this study, CheC-CheD binding kinetics with CheY or CheYp presence was successfully obtained by a series of SPR experiments. The increased affinity of CheD for CheC in presence of CheYp but not CheY makes likely the hypothesis that CheC-CheD-CheY interact as part of a negative feedback pathway during adaptation. Last, the interaction between CheD and chemoreceptor McpC was studied in order to better understand the role of CheD in adaptation. Results showed that Q304 and Q305 on McpC are essential to recruit CheD. Additionally, the reduced levels of CheD in mcpC (Q304A) or (Q305A) mutants suggested that the dynamic interaction between CheD and receptors is vital to maintain the normal CheD level. These findings suggest more complicated roles of CheD than its previously identified function as a receptor deamidase, and will lead to a clearer picture of the coordination of the three adaptational systems in the B. subtilis chemotactic sensory transduction system.

Towards participatory political theology: democratic consolidation in Southeastern Europe and the role of Eastern Christianity in the process

This thesis defends the position that the Eastern Orthodoxy has the potential to develop, on the basis of its core concepts and doctrines, a new political theology that is participatory, personalist and universalist. This participatory political theology, as I name it, endorses modern democracy and the values of civic engagement. It enhances the process of democracy-building and consolidation in the SEE countries through cultivating the ethos of participation and concern with the common good among and the recognition of the dignity and freedom of the person. This political-theological model is developed while analyzing critically the traditional models of church-state relations (the symphonia model corresponding to the medieval empire and the Christian nation model corresponding to the nation-state) as being instrumentalized to serve the political goals of non-democratic regimes. The participatory political-theological model is seen as corresponding to the conditions of the constitutional democratic state. The research is justified by the fact the Eastern Orthodoxy has been a dominant religiouscultural force in the European South East for centuries, thus playing a significant role in the process of creation of the medieval and modern statehood of the SEE countries. The analysis employs comparative constitutional perspectives on democratic transition and consolidation in the SEE region with the theoretical approaches of political theology and Eastern Orthodox theology. The conceptual basis for the political-theological synthesis is found in the concept and doctrines of the Eastern Orthodoxy (theosis and synergy, ecclesia and Eucharist, conciliarity and catholicity, economy and eschatology) which emphasize the participatory, personalist and communal dimensions of the Orthodox faith and practice. The paradigms of revealing the political-theological potential of these concepts are the Eucharistic ecclesiology and the concept of divine-human communion as defining the body of Orthodox theology. The thesis argues that with its ethos of openness and engagement the participatory political theology presupposes political systems that are democratic, inclusive, and participatory, respecting the rights and the dignity of the person. The political theology developed here calls for a transformation and change of democratic systems towards better realization of their personalist and participatory commitments. In the context of the SEE countries the participatory political theology addresses the challenges posed by alternative authoritarian political theologies practiced in neighboring regions.

Reading Pitscottie's Cronicles: a case study on the history of literacy in Scotland, 1575-1814

This thesis addresses a range of research questions regarding literacy in early modern Scotland. Using the early modern manuscripts and printed editions of Robert Lindsay of Pitscottie’s late sixteenth-century 'Cronicles of Scotland' as a case study on literacy history, this thesis poses the complementary questions of how and why early modern Scottish reading communities were encountering Pitscottie’s 'Cronicles', and how features of the material page can be interpreted as indicators of contemporary literacy practices. The answers to these questions then provide the basis for the thesis to ask broader socio-cultural and theoretical questions regarding the overall literacy environment in Scotland between 1575 and 1814, and how theorists conceptualise the history of literacy. Positioned within the theoretical groundings of historical pragmatics and ‘new philology’ – and the related approach of pragmaphilology – this thesis returns to the earlier philological practice of close textual analysis, and engages with the theoretical concept of mouvance, in order to analyse how the changing ‘form’ of Pitscottie’s 'Cronicles', as it was reproduced in manuscript and print throughout the early modern period, indicates its changing ‘function’. More specifically, it suggests that the punctuation practices and paratextual features of individual witnesses of the text function to aid the highly-nuanced reading practices and purposes of the discrete reading communities for which they were produced. This thesis includes extensive descriptive material which presents previously unrecorded data regarding twenty manuscripts and printed witnesses of Pitscottie’s 'Cronicles', contributing to a gap in Scotland’s literary/historiographical canon. It then analyses this material using a transferable methodological framework which combines the quantitative analysis of micro-data with qualitative analysis of this data within its socio-cultural context, in order to conduct diachronic comparative analysis of copy-specific information. The principal findings of this thesis suggest that Pitscottie’s 'Cronicles' were being read for a combination of devotional and didactic purposes, and that multiple reading communities, employing highly nuanced reading practices, were encountering the text near-contemporaneously. This thesis further suggests that early modern literacy practices, and the specific reading communities which employ them, should be described as existing within a spectrum of available practices (i.e. more or less oral/aural or silent, and intensive or extensive in practice) rather than as dichotomous entities. As such, this thesis argues for the rejection of evolutionary theories of the history of literacy, suggesting that rather than being described antithetically, historical reading practices and purposes must be recognised as complex, coexisting socio-cultural practices, and the multiplicity of reading communities within a single society must be acknowledged and analysed as such, as opposed to being interpreted as universal entities.

On the stability and spatiotemporal variance distribution of salinity in the upper ocean

Despite recent advances in ocean observing arrays and satellite sensors, there remains great uncertainty in the large-scale spatial variations of upper ocean salinity on the interannual to decadal timescales. Consonant with both broad-scale surface warming and the amplification of the global hydrological cycle, observed global multidecadal salinity changes typically have focussed on the linear response to anthropogenic forcing but not on salinity variations due to changes in the static stability and or variability due to the intrinsic ocean or internal climate processes. Here, we examine the static stability and spatiotemporal variability of upper ocean salinity across a hierarchy of models and reanalyses. In particular, we partition the variance into time bands via application of singular spectral analysis, considering sea surface salinity (SSS), the Brunt Väisälä frequency (N2), and the ocean salinity stratification in terms of the stabilizing effect due to the haline part of N2 over the upper 500m. We identify regions of significant coherent SSS variability, either intrinsic to the ocean or in response to the interannually varying atmosphere. Based on consistency across models (CMIP5 and forced experiments) and reanalyses, we identify the stabilizing role of salinity in the tropics—typically associated with heavy precipitation and barrier layer formation, and the role of salinity in destabilizing upper ocean stratification in the subtropical regions where large-scale density compensation typically occurs.

The problem posed by exam choice on the comparability of results in the Finnish matriculation examination

The article focuses on the upper secondary matriculation examination in Finland as a school leaving and university entrance examination. The presented research addresses the question of whether increased choice of the subject-specific examinations has the potential to undermine the comparability of examination results and to direct students’ choices not only in the examination but already beforehand at school. The authors refer to Finland’s tradition of more than 160 years of a national examination connecting the academic track of upper secondary schools with universities. The authors explain the Finnish system by describing the adoption of a course-based (vs. class- or year-based) curriculum for the three-year upper secondary education and the subsequent reforms in the matriculation examination. This increases students’ choices considerably with regard to the subject-specific exams included in the examination (a minimum of four). As a result, high-achieving students compete against each other in the more demanding subjects while the less able share the same normal distribution of grades in the less demanding subjects. As a consequence, students tend to strategic exam-planning, which in turn affects their study choices at school, often to the detriment of the more demanding subjects and, subsequently, of students’ career opportunities, endangering the traditional national objective of an all-round pre-academic upper secondary education. This contribution provides an overview of Finnish upper secondary education and of the matriculation examination (cf. Klein, 2013) while studying three separate but related issues by using data from several years of Finnish matriculation results: the relation of the matriculation examination and the curriculum; the problems of comparability vis-à-vis university entry due to the increased choice within the examination; the relations between students’ examination choices and their course selection and achievement during upper secondary school.

Clinical efficacy of paclitaxel in the treatment of mid-stage and advanced malignant gastric cancer, and effect of nursing interventions

Purpose: To investigate the clinical efficacy of paclitaxel combined with additional chemotherapy for mid-stage and advanced malignant tumors, and the benefits afforded by scientific nursing. Methods: Patients with mid-stage and advanced gastric cancer were randomly divided into test and control groups. Control group was given intravenous chemotherapy (400 mg/m2 fluorouracil and 2500 mg/m2 cisplatin) and nursed conventionally, while the test group was additionally treated with 80 mg/m2 paclitaxel and underwent special scientific nursing. Clinical effects and changes in the rates of apoptosis and cell proliferation were recorded. The effect of applying scientific nursing on therapeutic outcomes was also evaluated. Results: The overall rate of treatment effectiveness, clinical control rate, mean apoptosis and proliferation rates in the test group were 56.40, 92.30, (7.10 ± 3.17 and 28.70 ± 3.22 %, respectively, while, in the control group, the values were 38.50, 64.10, 25.40 ± 2.67 and 32.60 ± 2.93 %, respectively. The differences were all statistically significant (p < 0.05). In terms of nursing efficacy, the test group had a lower pain score and higher quality-of-life scores (Karnofsky performance status score) than control group. There was no significant difference in the incidence of adverse reactions between the two groups (p > 0.05). Conclusion: Paclitaxel has a significant effect when used to treat mid-stage and advanced gastric cancer. Moreover, additional nursing not only enhances the therapeutic effect but also improves prognosis and quality-of-life.
