Geochemical and Sr–Nd–Pb isotopic characteristics of basalt from eastern Hunan Province: New insight for the Late Cretaceous tectonic dynamic mechanism in South China

During the Late Cretaceous period, massive magmatism occurred in South China. Eastern Hunan Province is situated in the inland part of South China. Comparing with the coastal area, the inland of South China is characterized by the absence of intermediate‐acid intrusive rocks, but the occurrence of multiple mafic rocks. To date, the emplacement and triggering mechanism of magmatism of inland South China is still very puzzling. In this article, we address this question by concentrating on the basalt exposed in eastern Hunan Province. Geochronologically, three stages of zircon grains, which include xenocrysts and authigenic crystals (rare), are recognized, and the last stage of zircon grains with a concordant age of 79.93 ± 0.47 Ma (MSWD = 1.9) represents the actual crystallization age of basaltic magma. Geochemically, the basalt in eastern Hunan Province has low TiO2 and K2O contents (1.11–2.63 and 0.28–2.88 wt%) but high alkali contents (3.75–6.58 wt%) and K2O/Na2O ratios (0.05–0.56). The basalts from eastern Hunan Province are enriched in large‐ion lithophile elements and light rare earth elements and obviously depleted in heavy rare earth elements with weak negative Eu anomalies (Eu/Eu* = 0.87–1.26); they lack significant Ti, Nb, Ta, etc., depletions. These features are much different from those of coastal basalt with strong arc‐related signatures. The incompatible element ratios and Sr–Nd–Pb isotope compositions commonly imply significant EMII‐type OIB‐like source region and within‐plate basalt characteristics. The basalt may have suffered from earlier partial melting of garnet‐spinel peridotite and later rapid fractional crystallization of mafic minerals (olivine and pyroxene). Significant geochemical and petrological discrepancies between inland basalt and coastal basalt suggest a subduction‐absent within‐plate setting for inland basalt but a strong subduction‐related signature for coastal basalt. The magmatic age of mafic rocks from inland South China hold a significant tendency to become younger to the west. The spatial and temporal distribution and variation of components of basalt in South China indicated a mantle plume model which is derived from the 670 km thermal boundary layer (670 TBL) between the lower and upper mantle. The trigger mechanism of this model could be attributed to the westward steep rollback subduction of the Palaeo‐Pacific Plate in the Late Cretaceous.
Feasibility of Constructed Wetland Using Coagulation Flocculation Technology in Batik Wastewater Treatment

The batik industry became a double-edged sword for the development of Indonesia. While it plays a significant role in economy, it also contributes to the environmental pollution, which is mostly caused by the lack of appropriate technology for the wastewater treatment in small industries. This study aims at determining the feasibility in combining the coagulation-flocculation technology using Moringa oleifera seeds powder (MOSP) with horizontal subsurface constructed wetland (HSSFCW) in treating the batik wastewater. The results show that combining 750 mg/L MOSP in the coagulation flocculation technology with 5 days retention time on HSSFCW optimally removed 89.33% of the chemical oxygen demand (COD); 98.11% of total suspended solids (TSS); and 92.05% of fat, oil, and grease (FOG). Moreover, it increases the pH conditions up to 7.33. Despite its high removal efficiency, this technology combination is not feasible in the batik wastewater treatment due to inability to meet the standard effluent of the discharged wastewater. Therefore, adding pre-post treatment to this technology implementation is recommended to obtain the standard effluents of wastewater discharged.
Factors influencing learner autonomy and autonomy support in a faculty of education

ABSTRACT Most studies on learner autonomy are in language learning while those on autonomy support are in secondary schools, and are mainly of quantitative nature conducted with either teachers or learners. However, in-depth qualitative studies focusing on the factors influencing learner autonomy in higher education and autonomy support provided for student teachers by teacher educators are scarce. Drawing on data from a qualitative study carried out in an education faculty, this article focuses on both teacher educators’ and student teachers’ perceptions of the factors that limit learner autonomy practice and support. The findings suggest teacher/learner backgrounds, mismatch between teacher and learner expectations, spoon-feeding tendencies of teachers, limited teacher autonomy and large classes are the main factors. The findings also suggest that there exists a dynamic interaction between the constructs of learner autonomy, teacher support and teacher autonomy indicating these need to be treated together rather than in isolation.
Morphological Identification Of Inductive Signatures Using An Adaptive Resonance Theory Based Learning Scheme

This paper presents an algorithm that uses a learning scheme based on the Adaptive Resonance Theory – ART2 to identify morphological patterns in two classes of vehicle inductive signatures and to construct inductive signatures subclasses based on morphological similarities among inductive signatures and previously identified patterns. The algorithm is initialized using all inductive signatures of a class as inputs to the learning scheme. During the iterations of the algorithm, the inputs whose morphological similarity exceeds a pre-established threshold value are merged into a single new input to the learning scheme. The merging process stops when the threshold value can not be overcome. The remaining inputs are considered to be the desired group of patterns representing the morphological diversity of the inductive signature class. Next, the morphological patterns identified by the learning scheme are submitted to a clustering algorithm to form the subclasses. In some classification tasks, the problem of classes overlap in the input space can be approached under the point of view of the morphological similarity among groups of patterns of each class. In these cases, pre-processing the original input space dividing it into morphological subclasses serves to identify the regions where the classes overlap is concentrated and to break down the initial classification task, whose solution is more difficult, in minor tasks, hypothetically, easier to be resolved. However, the supposition that the division in subclasses led to a better separation of the two classes of inductive signatures will be checked in subsequent stages of our research through tests with neural classifiers.
Deposition of Synthetic and Bio-Based Polycations onto Negatively Charged Solid Surfaces: Effect of the Polymer Cationicity, Ionic Strength, and the Addition of an Anionic Surfactant

The deposition of layers of different polycations (synthetic or derived from natural, renewable resources) onto oppositely charged surfaces has been studied using ellipsometry and quartz crystal microbalance with dissipation monitoring (QCM-D). Information about the thickness of the deposited layers and their water content was ascertained. The adsorption of the different polycations onto negatively charged surfaces was found to be a complex process, which is influenced by the chemical nature of the polymer chains, ionic strength, polymer concentration and the addition of additives such as surfactants. The experimental picture shows a good agreement with theoretical calculations performed using the Self-Consistent Mean Field (SCF) approach. The results show that the electrostatically-driven deposition can be tuned by modifying the physico-chemical properties of the solutions and the chemical nature of the adsorbed polymer. This versatile approach is a big step forward in aiding the design of new polymers for many industrial applications and, in particular, the design of sustainable washing formulations for cosmetic applications.
Intermittency of Gravity Waves in the Antarctic Troposphere and Lower Stratosphere Revealed by the PANSY Radar Observation

The momentum fluxes associated with gravity waves (GWs) significantly vary both in time and space. It is important to qualify the intermittency of GWs because the intermittency largely affects the vertical profile of momentum flux convergences in the middle atmosphere. In this study, 1 year of continuous observation with high time/height resolution and accuracy was provided by the PANSY radar, a Mesosphere‐Stratosphere‐Troposphere (MST) radar at Syowa Station (69.01°S, 39.59°E) in the Antarctic. The PANSY radar is used to study the intermittency of GWs in the troposphere and lower stratosphere. In all seasons, the intermittency is large in the troposphere with Gini coefficients of 0.4–0.6 for absolute momentum fluxes ( ρou′w′¯ ) and 0.4–0.7 for vertical wind variances multiplied by the density ( ρow′2¯ ). However, the intermittency is small in the lower stratosphere with Gini coefficients of 0.3–0.5 for ρou′w′¯ and 0.2–0.4 for ρow′2¯ . The seasonal characteristics in the lower stratosphere are different between ρou′w′¯ and ρow′2¯ : small Gini coefficients are observed in May–July for ρou′w′¯ and in December–February for ρow′2¯ . Simple model experiments with ideal distributions of GWs as a function of momentum flux magnitude and ground‐based phase velocity are performed. These results indicate that the vertical profiles of the Gini coefficient obtained by the PANSY radar are largely affected by orographic GWs with large amplitudes. The results also suggest that the generation and the partial reflection of GWs play an important role in determining the vertical profile of GW intermittency.

Knowledge Management and Leadership Opportunities for Technical Communicators

INTRODUCTION: KNOWLEDGE MANAGEMENT’S MANY DEFINITIONS Like technical communication, knowledge management is hard to define. One reason for this difficulty is that the scope of both areas is so broad that they truly have different meanings for different professionals, different meanings for different organizations. Another reason is that when knowledge management is defined by various professionals, its breadth and complexity are rarely presented with adequate rigor or accuracy, a common occurrence in technical communication as well. Much of this over-simplification results from the human need to categorize concepts (and professions) in such a way that they match our preconceptions of them. Most veteran technical communicators have experienced the difficulty of explaining their profession to laypeople or professionals outside our field. “Knowledge officers” at all levels are currently experiencing these same difficulties. It is well documented that there is a multitude of seemingly divergent definitions of knowledge management. Some emphasize information development and document management (Thurman 1999; Applehans, Globe, and Laugero 1999). Some concentrate primarily on the technology surrounding documents and information (a quick perusal of KMWorld or CIO magazine will illustrate this point). Others emphasize the financial value of knowledge as intangible assets or “intellectual capital” (Sveiby 1997; Edvinsson and Malone 1997; Roos 1998; Stewart 1997). Some emphasize cultural issues (Leonard-Barton 1995; De Geus 1997), and still others talk about “knowledge organizations” (Nonaka and Takeuchi 1995; Davenport and Prusak 1998; Koulopoulos, Spinello, and Toms 1997). Understanding knowledge management, however, is less confusing when we understand that the multiple definitions are relative to the context in which they are used, most notably the disciplinary influences of the people implementing knowledge management and the organizations in which it is implemented. Thus, it is only logical that people with accounting or finance backgrounds think of knowledge management in terms of “intellectual capital,” focusing on aims of maximizing a company’s revenues by fully leveraging the collective know-how (intellectual capital) of its people. Similarly, technical communicators will likely think of knowledge management as extracting and synthesizing knowledge from people with specialized knowledge (usually subject matter experts) and developing it into an easily understandable form (print or Web documents, multimedia applications, help files) for people who lack that knowledge. Furthermore, technologists (programmers, developers, corporate chief information officers) might think of knowledge management as developing knowledge management applications (portals, groupware, databases), implementing pre-packaged applications, and maintaining the information technology infrastructure needed to support these applications. In sum, all these conceptions of knowledge management are accurate, but each of them emphasizes only one aspect of the complexity of the concept.
Computational Approaches for the Interpretation of ToF-SIMS Data.

High surface sensitivity and lateral resolution imaging make Time-of-Flight SecondaryIon Mass Spectrometry (ToF-SIMS) a unique and powerful tool for biologicalanalysis. Many of these biological systems, including drug-cell interactions, requireboth the identification and location of specific chemicals. ToF-SIMS, used in imagingmode, is making great strides towards the goal of single cell and tissue analysis.The experiments, however, result in huge volumes of data. Here advanced computationalapproaches employing sophisticated techniques to convert these data intoknowledge are introduced.This thesis aims to produce a framework for data analysis, integrating novel algorithms,image analysis and 3D visualisation. New schema outlined in this thesisaddress the issues of the immense size of 3D image stacks and the complexity containedwithin the enormous wealth of information in ToF-SIMS data.To deal with the issues of size and complexity of ToF-SIMS data, new techniquesto processing image data are investigated. Automated compression routines for ToF-SIMSimages using a peak picking routine tailored for ToF-SIMS are evaluated. Newuser friendly GUIs capable of processing and visualising very large image stacks areintroduced as part of a tool-kit designed to streamline the process of multivariateanalysis and image processing. Along with this two well known classification routines,namely AdaBoost and SVMs, are also applied to ToF-SIMS data of severalbacterial strains to test their ability to classify SIMS data accurately. This thesispresent several new approaches to data processing and interpretation of ToF-SIMSdata.
Composing in English: a study of the effects of L1 or L2 planning and topic choice by Japanese learners of English

Often when teaching oral communication, great emphasis is placed on the use of target English language only in the classroom. Reasons often given to defend this policy include the use of L1 in learning English causes unwanted language interference and extended “thinking-time” slowing down a conversation. However this may not be the best policy when producing L2 writing, particularly in the early planning stage where the use of L1 might in fact reduce cognitive loads on L2 writers especially if the topic of the writing is linked to a writer’s L1 and may be best recalled in L1. This PhD study explores the questions and reservations regarding the optimum methods of planning an English essay by Japanese writers of L2 English, both in the UK and in Japan, at intermediate and advanced proficiency levels, with particular focus on the variables of language of planning and topic choice The overarching aims of this PhD study are * To investigate whether planning in L1 about an L1 related topic or planning in L2 about an L2 related topic (language and topic match conditions) enhances L1 Japanese writers’ final essay texts in L2 English. * To investigate whether topic choice independent of planning language, or planning language independent of topic choice (language and topic mismatch conditions) have any impact on plans or resulting L2 English final essay texts. This investigation takes place in three common contexts in which L1 Japanese writers of L2 English operate. The design of the study and methods used to collect, analyse, discuss and compare data are done both quantitatively and qualitatively, that is empirically and also hermeneutically.
Computer Games and Team and Individual Learning

Documents research on the impact of computer games on the learning of adults. Computer games and learning are characterized from a series of different theoretical and empirical viewpoints. Both civilian sector and military applications are presented. While effectiveness of game environments to support learning can be documented in terms of intensity and longevity of engagement (participants voting with their time), as well as the commercial success of the games, there is much less solid empirical information about what instructional outcomes are systematically achieved by the playing of individual and multiplayer games. This book will address these issues.Designed for professionals in the gaming, simulation, assessment and evaluation, educational technology, and educational psychology communities, this book explores the state of the art in the use of computer game technology for teaching and measurement of learning in adults. Its unique focus is on the empirical impact, both qualitative and quantitative, of computer games on the learning of adults.
A Database-driven Model for Risk Assessment

Securing valuable information assets is a problem that cuts across multiple industries and organizational missions. Using a database-driven approach to risk assessment, we developed a database model based on prior conceptual work in information security. Our approach is novel in that, as a risk assessment model, it emphasizes harnessing the advantages of a relational database approach to improve the efficiency and scope of risk assessment. Our method was proof of concept. We illustrated the database model’s use, implementing it within a single domain—healthcare—and applied it to a single hypothetical scenario. The result was that the implemented database produced a resultant list of threats and countermeasures for the given health security scenario. Future work includes testing the approach with clients across multiple domains. The work has the potential to provide valuable risk-related, cross-domain benefits.

Heterogeneous Concurrent Modeling and Design in Java (Volume 3: Ptolemy II Domains)

Abstract : This volume describes Ptolemy II domains. The domains implement models of computation, which are summarized in chapter 1. Most of these models of computation can be viewed as a framework for component- based design, where the framework defines the interaction mechanism between the components. Some of the domains (CSP, Rendezvous, DDE, and PN) are thread-oriented, meaning that the components implement Java threads. These can be viewed, therefore, as abstractions upon which to build threaded Java programs. These abstractions are much easier to use (much higher level) than the raw threads and monitors of Java. Others (CT, DE, SDF) of the domains implement their own scheduling between actors, rather than relying on threads. This usually results in much more efficient execution. The Giotto domain, which addresses real-time computation, is not threaded, but has concurrency features similar to threaded domains. The FSM domain is in a category by itself, since in it, the components are not producers and consumers of data, but rather are states. The non-threaded domains are described first, followed by FSM and Giotto, then the threaded domains followed by two newer domains, HDF and DDF. Volume 1 is an introduction to Ptolemy II, including tutorials on use of the software, and volume 2 describes the Ptolemy II software architecture.
