Examining Community Perceptions of Energy Systems Development: The Role of Communication and Sense of Place

An increasing demand for the development and implementation of low carbon energy systems has furthered the need to understand the factors that influence a community's support for or opposition to local energy developments. Carbon dioxide capture and geological storage (CCS) is one such energy system where it is widely acknowledged that public perceptions and acceptance of CCS technologies are critical to their implementation. CCS refers to the capture of carbon dioxide emissions from industrial sources and the long-term storage of these emissions in stable underground reservoirs. This case study examines how place attachment and community networks factored into resident's perceptions of a proposed CCS project that was ultimately canceled due to local opposition. Participants were concerned about preserving shared places, spaces, and interactions that were valued by community members. Results demonstrate the need to ascertain how locally affected populations view CCS or other energy developments, especially with regard to their ideas about community, sense of place (ties to area and local relationships), and how they communicate about those factors. Such factors are important given the initiative to develop low carbon energy systems in rural areas.
A Multi-Domain Web-Based Algorithm for POS Tagging of Unknown Words

We present a web-based algorithm for the task of POS tagging of unknown words (words appearing only a small number of times in the training data of a supervised POS tagger). When a sentence s containing an unknown word u is to be tagged by a trained POS tagger, our algorithm collects from the web contexts that are partially similar to the context of u in s, which are then used to compute new tag assignment probabilities for u. Our algorithm enables fast multi-domain unknown word tagging, since, unlike previous work, it does not require a corpus from the new domain. We integrate our algorithm into the MXPOST POS tagger (Ratnaparkhi, 1996) and experiment with three languages (English, German and Chinese) in seven in-domain and domain adaptation scenarios. Our algorithm provides an error reduction of up to 15.63% (English), 18.09% (German) and 13.57% (Chinese) over the original tagger.
Bullying Allegations from the Accused Bully's Perspective

Research on workplace bullying to date has relied predominantly on self-reports from targets and bystanders, largely ignoring the contributions of other stakeholders such as the alleged perpetrator. This study aims to close this gap by focusing on the perspectives of the alleged perpetrator and examining the background of the bullying allegations, the types of behaviours labelled as bullying and the perpetrator's justification of their behaviours. Twenty-four managers who were accused of workplace bullying were interviewed for this study, and a thematic analysis of the interview transcripts was undertaken. Many participants reported a highly stressful workplace, including ambiguous roles, staff shortages and high levels of conflict, as well as inappropriate social behaviours being carried out by others in addition to themselves. A number of participants viewed themselves as targets of bullying by their staff, and others defended their behaviour as legitimate performance management.
Expression of Neuronal Traits in Pancreatic Beta Cells

Pancreatic beta cells (insulin-producing cells) and neuronal cells share a large number of similarities. Here, we investigate whether the same mechanisms could control the expression of neuronal genes in both neurons and insulin-producing cells. For that purpose, we tested the role of the transcriptional repressor neuron-restrictive silencing factor/repressor element silencing transciption factor (NRSF/REST) in the expression of a battery of neuronal genes in insulin-producing cells. NRSF/REST is a negative regulator of the neuronal fate. It is known to silence neuronal-specific genes in non-neuronal cells. We demonstrate that, as in the case of the neuronal pheochromocytoma cell line PC12, mRNA coding for NRSF/REST is absent from the insulinoma cell line INS-1 and from three other insulin- and glucagon-producing cell lines. NRSF/REST activity is also absent from insulin-producing cell lines. Transient expression of REST in insulin-producing cell lines is sufficient to silence a reporter gene containing a NRSF/REST binding site, demonstrating the role of NRSF/REST in the expression of neuronal markers in insulin-producing cells. Finally, by searching for the expression of NRSF/REST-regulated genes in insulin-producing cells, we increased the list of the genes expressed in both neurons and insulin-producing cells.
Dialogue and the Development of Children's Thinking: A Sociocultural Approach

Even casual observations of children's everyday lives reveal that they are constantly engaged in talk and other forms of social interaction. Dialogue and the Development of Children’s Thinking provides a clear, accessible and well-illustrated case for the importance of spoken dialogue for children’s intellectual development during the school years. The book draws on extensive research to provide a ground-breaking new account of this relationship, and closely relates the research findings to real-life classrooms, so that it is of practical value to teachers and parents concerned that their children are offered the best possible learning opportunities. Importantly, it provides hard evidence from original research to show that the quality of classroom talk improves the quality of children’s thinking and educational attainment. The book also provides a new and more educationally-relevant interpretation of sociocultural theory, based on the work of Vygotsky, which explains the fascinating relationship between engagement in dialogues and learning. By using evidence of how the collective construction of knowledge is achieved, and how engagement in dialogues shapes children's educational progress and intellectual development, the authors provide a text which will be essential for educational researchers, postgraduate students of education and teachers, and also of interest to many psychologists and applied linguists.
Virtual Identity : Risk or Resource ? A Study about Effects of Using Social Network and Multi-User Virtual Environment ( MUVE ) on Processes of Identity Construction Of Emerging Adults

Using internet to build own social-relational system is an increasingly widespread phenomenon. It revolves both very young people and emerging adults [2] for which the dimensions of identity exploration often seemed to constitute areas of uncertainty and risk [1]. The motivation factors to use a social network are related to self-presentation and socialization [13],[19]. On the other hand, it was demonstrated [8] that the use of virtual environment and/or social networks for continuous and sustained periods can have directly negative effects on selfdefinition processes [3], [4]. Therefore, the goal of this explorative contribution is to study the effects of using of virtual environment and/or social networks in terms of risks and resources on processes of identity construction of emerging adults. It was used a narrative format of survey (autobiographical narrative interview) [5] [6], considered one of the most suitable instruments to analyze the construction processes of narrative identity. Participants are 25 emerging adults (average age 23 years), balanced by gender. The texts produced were analyzed by lexical content analysis, which identifies semantic worlds of texts, through lexical cluster analysis [17]. Results show the presence of 4 lexical clusters (with a stability index of 78%) related to self construction processes (Cluster 1: Curiosity and exploration; Cluster 2: The need for affiliation and masking of emotions; Cluster 3: The “potential self”; Cluster 4: The mask effect) and they highlight the existence of risks associated with the construction of identity, but also benefits linked to the relational and emotional dimensions of the self. That finding underlines the need for a thorough study of the effects of the use of new technologies in order to plan for such use in education.
CULTURE AND WOMEN ABUSE: Some South African starting points

THERE HAS been growing debate in South Africa in recent months about the impact of culture (or, more accurately, of 'cultural arguments') on the advancement of 'women's rights'. This is not surprising. The changing political climate makes it possible for the first time to contemplate a democratic future for the country and to debate what form such a democracy should take. Constitutional proposals from both ends of the political spectrum consistently stress the 'multi-cultural' nature of South African society and appeal for the preservation, in one form or another, of such identities.
Finite Frequency Tests for Robust Performance of Systems with Real Parameter Uncertainty

In this paper we deal with input-single single-output plant families with linear real parameter uncertainty in the numerator and denominator of their transfer functions. We further assume that the controller has been chosen and a bound given on the sensitivity. We develop a finite test for checking robust performance (tracking in this case), one that involves a finite number of frequencies.
Design and evaluation of multifield visualisation techniques for 2D vector fields

The visualisation of vector fields is essential for many applications in science, engineering and biomedicine. A large number of vector icons has been developed, but little research has been done on their effectiveness, especially when visualising multiple vector fields simultaneously. We apply research in visualisation and cognitive science to identify four classes of post-processing techniques for visualising two 2D vector fields simultaneously: blending, overlay, bump mapping, and masking. We apply these four post-processing methods to Line Integral Convolution (LIC) textures and thus develop several novel multi-field visualisation techniques. We evaluate their effectiveness with a user study requiring participants to locate and classify singularities, and to rate each method on its effectiveness and aesthetic value. The results of the study suggest that blending is the most effective technique to combine multiple vector field visualisation textures, while masking performs worst. There is some evidence that visualisations with smooth colour changes are perceived as visually more attractive, and that aesthetics increases the perceived effectiveness of a visualisation technique.
The Structuring of a World Environmental Regime, 1870–1990

In recent decades a great expansion has occurred in world environmental organization, both governmental and nongovernmental, along with an explosion of worldwide discourse and communication about environmental problems. All of this constitutes a world environmental regime. Using the term regime a little more broadly than usual, we define world environmental regime as a partially integrated collection of world-level organizations, understandings, and assumptions that specify the relationship of human society to nature. The rise of an environmental regime has accompanied greatly expanded organization and activity in many sectors of global society. Explaining the growth of the environmental regime, however, poses some problems. The interests and powers of the dominant actors in world society—nation-states and economic interests—came late to the environmental scene. Thus these forces cannot easily be used to explain the rise of world mobilization around the environment, in contrast with other sectors of global society (for example, the international economic and national security regimes).
Advances in Brief Reversal of GSTP 1 CpG Island Hypermethylation and Reactivation of-Class Glutathione S-Transferase ( GSTP 1 ) Expression in Human Prostate Cancer Cells by Treatment with Procainamide 1

Among the many somatic genome alterations present in cancer cells, changes in DNA methylation may represent reversible “epigenetic” lesions, rather than irreversible “genetic” alterations. Cancer cell DNA is typically characterized by increases in the methylation of CpG dinucleotides clustered into CpG islands, near the transcriptional regulatory regions of critical genes, and by an overall reduction in CpG dinucleotide methylation. The transcriptional “silencing” of gene expression associated with such CpG island DNA hypermethylation presents an attractive therapeutic target: restoration of “silenced” gene expression may be possible via therapeutic reversal of CpG island hypermethylation. 5-Aza-cytidine (5-aza-C) and 5-aza-deoxycytidine (5-aza-dC), nucleoside analogue inhibitors of DNA methyltransferases, have been widely used in attempts to reverse abnormal DNA hypermethylation in cancer cells and restore “silenced” gene expression. However, clinical utility of the nucleoside analogue DNA methyltransferase inhibitors has been limited somewhat by myelosuppression and other side effects. Many of these side effects are characteristic of nucleoside analogues that are not DNA methyltransferase inhibitors, offering the possibility that nonnucleoside analogue DNA methyltransferase inhibitors might not possess such side effects. Human prostate cancer (PCA) cells characteristically contain hypermethylated CpG island sequences encompassing the transcriptional regulatory region of GSTP1, the gene encoding the -class glutathione S-transferase (GSTP1), and fail to express GSTP1 as a consequence of transcriptional “silencing. ” Inactivation of GSTP1 by CpG island hypermethylation, the most common somatic genome alteration yet reported for human PCAs, occurs early during human prostatic carcinogenesis and results in a loss of GSTP1 “caretaker” function, leaving prostate cells with inadequate defenses against oxidant and electrophile carcinogens. We report here that the drug procainamide, a nonnucleoside inhibitor of DNA methyltransferases, reversed GSTP1 CpG island hypermethylation and restored GSTP1 expression in LNCaP human PCA cells propagated in vitro or in vivo as xenograft tumors in athymic nude mice.
Overexpression of claudin‐3 and claudin‐4 receptors in uterine serous papillary carcinoma

Uterine serous papillary carcinoma (USPC) represents a highly aggressive variant of endometrial cancer. Using gene expression profiling, we recently identified high expression of the claudin‐3 and claudin‐4 receptors in a limited set of USPC. These tight junction proteins represent the low‐ and high‐affinity receptors, respectively, for the cytotoxic Clostridium perfringens enterotoxin (CPE) and are sufficient to mediate CPE binding and trigger subsequent toxin‐mediated cytolysis. The potential for targeting this pathway in the treatment of USPC was explored.
PaaS on IaaS

In the current cloud era, new cloud skills are required for IT specialists. Educational organizations such as universities need to provide an educational cloud for their students. We have constructed a private educational cloud based on the Ubuntu Enterprise Cloud. The most important feature of our cloud is super saturation, which is defined as allocating more logical resources than actual physical resources. A supersaturated cloud is able to run more than 10times the number of instances than a conventional cloud. Although there is a slight drop in performance, the cost decreases drastically. We propose a Platform as a Service(PaaS) on an Infrastructure as a Service (IaaS) (PoI) method to further improve the utilization of the educational cloud based on super saturation. In this paper, we compare two methods for creating PoI applications, Single Tenant PaaS and MultiTenant PaaS, where the former allows applications to be installed easily, whereas the latter achieves high convergence.
Effects of Thyroid Hormone on Androgen-or Basic Fibroblast Growth Factor-induced Proliferation of Shionogi Carcinoma 115 Mouse Mammary Carcinoma Cells in Serum-free Culture 1

DNA synthesis of SC-3 cells cloned from mouse mammary carcinoma (Shionogi carcinoma 115) was remarkably enhanced by androgen as well as basic fibroblast growth factor (bFGF) at the early phase (days 1-3) of stimulation in serum-free culture condition. However, bFGF-induced DNA synthesis could not be observed at the late phase (days 4-6) of stimulation while androgen was able to continuously elicit DNA synthesis. When the effect of androgen on cell yield was examined, the cell number was increased while bFGF could not enhance cell growth. Androgeninduced heparin-binding growth factor partially purified from conditioned medium behaved like bFGF in terms of DNA synthesis and replication in SC-3 cells. SC-3 cells were found to contain the high-affinity binding site toward triiodothyronine. The dissociation constant and the maximum number of the binding sites were 7 x 10~'Â°M and 1800/cell, respectively. Triiodo thyronine significantly blunted the testosterone-induced DNA synthesis. On the other hand, bFGF-enhanced DNA synthesis was not substantially inhibited by triiodothyronine. These results suggest that androgen, but not bFGF, has unique action site(s) which might be important for SC-3 cell replication and might be antagonized by thyroid hormone. (GC cells) has also been observed to be enhanced by thyroid hormone (9, 10). Thyroid hormone receptor belongs to the steroid/thyroid/vitamin receptor superfamily (11). Thyroid hormone might possibly modulate steroid hormone actions. Actually, interactions between thyroid and steroid hormones have been reported with respect to the control of neoplastic growth (12). In this relation, thyroid hormone has been reported to inhibit the growth of Shionogi carcinoma cell line in FCSsupplemented culture (13, 14). PCS has been known to contain various growth control factors which may complicate the inter pretation of the data on growth-stimulatory or -inhibitory ef fects of thyroid hormone. The present experiments were designed to study the effects of androgen, bFGF and/or thyroid hormone on SC-3 cell growth in serum-free culture. The results show that androgen stimulates both DNA synthesis and proliferation of SC-3 cells while bFGF enhances only the DNA synthesis without increas ing the cell yield. Thyroid hormone suppresses effectively the growth-stimulatory ability of androgen but less effectively that of bFGF.
Studies on a mutant strain of Escherichia coli which requires both methionine and lysine for growth.

SUMMARY: A mutant of Escherichia coli was isolated which showed a requirement for methionine+lysine when a fairly large inoculum of washed organisms was used. Cystathionine or homocysteine replaced methionine, and diaminopimelic acid replaced lysine; no other amino acid or growth factor was active. The amounts of the amino acids required to promote growth were only about one-tenth of the quantity of methionine and lysine found in the grown organisms. A quantitative study with 14C-glucose and 35S-sulphate confirmed that these amino acids were synthesized de novo. Although homoserine would not replace methionine for growth, the presence of unlabelled homoserine suppressed the incorporation of isotope from 14C-glucose into methionine and threonine, indicating that the accepted pathways are operative and that the block in methionine synthesis was in the formation of cystathionine. Small amounts of yeast extract replaced the amino acid requirement and decreased one-thousandfold the size of the inoculum required.
Sensorless control of brushless DC motors at low speed using neural networks

A sensorless control method of brushless DC (BLDC) motors is presented in this paper. Differently from the previous ones, this method is based on the zero crossing of line back EMFs, which is proofed corresponding to the commutation points and more reliable at low speeds. For the accuracy and robust of the method, an artificial neural network with a section dealing with the outliers is also employed to estimate the line back EMFs by only using measurements of the stator line voltages and currents. The method provides more wide-speed range, and no neutral voltage, phase shifted or silent phase required. A simulation result of the proposed sensorless method is shown. Also, the performance of the proposed method is verified by real-time experiments using the digital signal processor (DSP) TMS320LF2407A.
Temperature dependent on electrical properties of swine liver from 0.3 MHz to 30 MHz

With the spread of the mobile radio terminals, a lot of studies about electrical properties of human in the ultra-high frequency (UHF) band and above have been made. However, few studies have been made in lower frequency than UHF. In this study, we measured the electrical properties of swine liver with changing temperatures and frequencies from 300 kHz to 30 MHz.
Testing for Employee Discrimination Using Matched Employer-Employee Data: Theory and Evidence

In this paper, we directly test Becker’s theory of employee discrimination using matched worker-workplace data from Britain. Based on a structural model with individual and firm heterogeneity, we develop and test two predictions. Firstly, if white employees have a taste for discrimination they should report lower levels of job satisfaction the larger the proportion of ethnic minorities at their workplace. Secondly, white employees’ wages should also increase with the concentration of ethnic minority co-workers. Both hypotheses are strongly supported for white males in our data, after controlling for human capital and job amenity variables, though not for females. The white male wage premium for working amongst only ethnic minority co-workers, as compared to working only with whites, is about 12%. Neither of these effects operate via realised racial prejudice at the workplace or employees’ feelings concerning job security.
A Mixed Coding Scheme for Inverted File Index Compression

Cluster property of d-gaps in inverted lists provides valuable information for improving index compression and subsequently improving the performance of Web search engines. By clustering d-gaps of an inverted list strictly based on a threshold, and then encoding clustered and non-clustered d-gaps using different methods, we can tailor to the specific properties of different d-gaps and achieve better compression ratio. Based on this idea, in this paper we propose a cluster based mixed coding scheme for inverted file index compression: mixed gamma/flat binary code. Experiment results show that the new coding scheme achieves at least equal performance in terms of compression ratio comparing to interpolative code which is considered as one of the most efficient bitwise codes at present. By adjusting the parameters for the new code, even better results can be achieved. Besides, the new code has lower complexity comparing to interpolative code and therefore enables faster encoding and decoding
Teaching Operating Systems Concepts with SystemTap

The study of operating systems is a fundamental component of all undergraduate computer science degree programmes. Making operating system concepts concrete typically entails large programming projects. Such projects traditionally involve enhancing an existing module in a real-world operating system or extending a pedagogical operating system. The latter programming projects represent the gold standard in the teaching of operating systems and their value is undoubted. However, there is room in introductory operating systems courses for supplementary approaches and tools that support the demonstration of operating system concepts in the context of a live, real-world operating system. This paper describes an approach where the Linux monitoring tool SystemTap is used to capture kernel-level events in order to illustrate, with concrete examples, operating system concepts in the areas of scheduling, file system implementation and memory management. For instructors and students (where often for the latter seeing is believing) this approach offers an additional simple and valuable resource for solidifying understanding of concepts that might otherwise remain purely theoretical.
