What is a discourse approach to Twitter, Facebook, YouTube and other social media: connecting with other academic fields?

The wider field of discourse studies is still only beginning to turn its attention to social media despite a number of notable scholarly works. But as yet there has been little that has dealt specifically with issues of multicultural discourse – how language, identity, cross-cultural social relations and power play out in the rapidly evolving landscape of social media. In this paper, I show why discourse studies must engage with theories and empirical work on social media across academic fields beyond discourse studies and linguistics, at how these can help best frame the kinds of research that needs to be done, how to best formulate some of the basic questions of critical discourse analysis for this new communicative environment. I use this as a platform to point to the areas where multicultural discourse studies can work – where all the ambiguities of former studies of ‘identity’ and ‘culture’ are present, but realised in new ways. Yet these new forms of communication are fused into wider patterns of changing cultural values about forms of social structure, knowledge itself and the kinds of issues that tend to form our individually civic spheres.
Memory B-Cell and Antibody Responses Induced by Plasmodium falciparum Sporozoite Immunization

Background Immunization of healthy volunteers during receipt of chemoprophylaxis with Plasmodium falciparum sporozoites (CPS-immunization) induces sterile protection from malaria. Antibody responses have long been known to contribute to naturally acquired immunity against malaria, but their association with sterile protection after whole sporozoite immunization is not well established. We therefore studied the induction and kinetics of malaria parasite antigen-specific antibodies and memory B-cells (MBCs) during CPS-immunization and their correlation with protection from challenge infection. Methods We assessed humoral reactivity to 9 antigens representing different stages of the life cycle of P. falciparum by performing standardized MBC enzyme-linked immunospot and enzyme-linked immunosorbent assays on peripheral blood mononuclear cells and plasma samples from 38 Dutch volunteers enrolled in 2 randomized controlled clinical trials. Results MBCs and antibodies recognizing pre-erythrocytic and cross-stage antigens were gradually acquired during CPS-immunization. The magnitude of these humoral responses did not correlate with protection but directly reflected parasite exposure in CPS-immunization and challenge. Conclusions Humoral responses to the malarial antigens circumsporozoite protein, liver-stage antigen-1, apical membrane antigen-1, and merozoite surface protein-1 do not to predict protection from challenge infection but can be used as sensitive marker of recent parasite exposure. Clinical Trials Registration NCT01236612 and NCT01218893.
Harmonia: Balancing compute and memory power in high-performance GPUs

In this paper, we address the problem of efficiently managing the relative power demands of a high-performance GPU and its memory subsystem. We develop a management approach that dynamically tunes the hardware operating configurations to maintain balance between the power dissipated in compute versus memory access across GPGPU application phases. Our goal is to reduce power with minimal performance degradation. Accordingly, we construct predictors that assess the online sensitivity of applications to three hardware tunables-compute frequency, number of active compute units, and memory bandwidth. Using these sensitivity predictors, we propose a two-level coordinated power management scheme, Harmonia, which coordinates the hardware power states of the GPU and the memory system. Through hardware measurements on a commodity GPU, we evaluate Harmonia against a state-of-the-practice commodity GPU power management scheme, as well as an oracle scheme. Results show that Harmonia improves measured energy-delay squared (ED2) by up to 36% (12% on average) with negligible performance loss across representative GPGPU workloads, and on an average is within 3% of the oracle scheme.
D.10 - ANTIDEPRESANT PROPERTIES OF 3αC SUBSTITUTED DERIVATIVES OF PREGNANOLONE, A NOVEL USE-DEPENDENT NMDA ANTAGONISTS

replaced with clean black ones, and returned for a 3-min retention trial during which the proportion of entries into and the time spent in the preferred novel arm that had changed from white to black are recorded. Both doses of fluoxetine and venlafaxine reduced entries into the changed arm for males only, and the lower dose of reboxetine reduced entries for both sexes combined. Both doses of venlafaxine and the lower dose of reboxetine also reduced time spent on the changed arm for males only, whereas the lower dose of fluoxetine reduced this measure for both sexes combined. The results suggested sexand dose-related interference with short-term memory following all three drugs that were less obvious for reboxetine, and for female rats.

The Geneticist Who Played Hoops with My DNA … And Other Masterminds from the Frontiers of Biotech, by David Ewing Duncan (2005) HarperCollins, New York.

While the future of human existence is literally being forged by todays genetic scientists and biotechnology leaders, the media, policymakers, ethicists, and fellow scientists alike have not been adequately communicating the tremendous potential that is c ontained in these individuals work. With the public only vaguely aware of what is really happening, a new coterie of geniuses, tinkerers, tycoons, and genetic soothsayers are -for better or worse -about to alter life on earth forever.
Non-genomic effects of steroid hormones on membrane channels.

Steroid hormones may possess two distinct actions, a delayed genomic influence and the rapid nongenomic effects, which may act in concert. Nongenomic effect may be mediated by putative membrane receptors or due to allosteric interactions of steroids with membrane proteins (e.g. ionic channels), inducing rapid changes in protein/receptor/channel activation or inhibition.
Rede ning the weak/strong distinction

The classi cation of nominal expressions as weak vs. strong, rst suggested in Milsark 1974, has become central in the explanation of many phenomena at the syntax/semantics/pragmatics interface. As an increasing variety of data have been argued to be sensitive to the distinction, a corresponding variety of re nements in the de nitions of weakness and strength have been proposed. These re nements can be grouped into three general categories, according to whether they treat the distinction in terms of determiner characteristics (e.g. Barwise and Cooper 1981), discourse semantic properties such as presupposition or speci city (e.g. Diesing 1992, de Hoop 1992), or semantic type (e.g. Ladusaw 1994). In this paper, we consolidate the arguments for the third of these approaches, and more speci cally, for the de nitions of weak and strong characterized as follows (cp. Ladusaw 1994 and also Dobrovie-Sorin 1997 for a related proposal):
Acute Stroke Trials: The Problems of Local Investigators?

During stroke trials local investigators have to face many practical problems and time consuming procedures (filling in huge case report forms, performing repeat blood sample drawings for pharmacokinetic studies etc.) which, however, simply require organizational structures which is understood to be necessary to be able to conduct such kind of studies. Other, and most worrisome problems, are indeed to be solved when a sponsored research may rise potential ethical issues, or when academic research proposals clash with the interest of pharmaceutical companies or find difficulties in being funded by public institutions. It is just a greater involvement of these latter, possibly free from bureaucratic laces, which might help a balance to be struck between academic and industrial aims.
Efficient Measurement of Complex Networks Using Link Queries

Complex networks are at the core of an intense research activity. However, in most cases, intricate and costly measurement procedures are needed to explore their structure. In some cases, these measurements rely on link queries: given two nodes, it is possible to test the existence of a link between them. These tests may be costly, and thus minimizing their number while maximizing the number of discovered links is a key issue. This paper studies this problem: we observe that properties classically observed on real-world complex networks give hints for their efficient measurement; we derive simple principles and several measurement strategies based on this, and experimentally evaluate their efficiency on real-world cases. In order to do so, we introduce methods to evaluate the efficiency of strategies. We also explore the bias that different measurement strategies may induce.
Convergence of Vectors in Paired Comparison-based Interactive Differential Evolution for Creating Scent

Creation of scent suited to each user will contribute for more efficient aromatherapy and use of scent in daily life. We have already proposed Interactive Differential Evolution (IDE) that creates user scent and have demonstrated the evolution of scent. In the proposed method, simple paired comparison between two scents was corresponded to comparison between target and trial vectors in general Differential Evolution (DE). However, detail observation of DE’s vector in the proposed method was not performed. This study investigated change and convergence of DE vectors in the proposed method. The investigation will contribute to develop more effective algorithm of IDE.
Microbiolgy Chlamydia trachomatis , Mycoplasma hominis , Mycoplasma genitalium , and Ureaplasma urealyticum in Patients with Sterile Pyuria in Gaza-Palestine Prepared

Objectives. To determine the occurrence of Chlamydia trachomatis, Mycoplasma hominis, Mycoplasma genitalium, and Ureaplasma urealyticum in patients with sterile pyuria. Design. Sterile pyuria urine samples collected during the period from February 2006 to April 2007 were tested by polymerase chain reaction (PCR) for the presence of C. trachomatis, M. hominis, M. genitalium, and U. urealyticum using specific primers for each species. Samples. Urine samples were collected from 200 patients (96 male, 104 female) aged ≥ 18 years attending the genitourinary clinic at Al-Shifa hospital, Gaza. Results. The PCR amplified DNA from 38 of the 200 urine samples (19%) from patients with sterile pyuria. C. trachomatis was detected in 20 samples (10%), U. urealyticum in 10 samples (5%), M. hominis in 6 samples (3%) and M. genitalium in 2 samples (1%). The difference in occurrence of C. trachomatis was statistically insignificant between males and females (P=0.509) but, it was significant (P=0.008) for U. urealyticum . M. hominis was detected only in samples collected from female patients. On the other hand, M. genitalium was detected only in men Conclusion. PCR testing of sterile pyuria showed a significant number of C. trachomatis, Mycoplasma , and Ureaplasma infections. Consequently PCR is recommended for the detection of those microorganisms in the urine samples of sterile pyuria patients.
Objetos de expressão e questionamento: consumo afetivo e a formulação de diretrizes pessoais Expression and questioning objects: affective consumption and the development of personal guidelines

This paper describes studies in emotional design, relating them to Mihaly Csikszentmihalyi and Eugene Rochberg-Halton's term Cultivation. It demonstrates how affective values in objects develop themselves in their capacity of directing the user's attention to personal achievements, values and goals. Conducted with users of various musical instruments, points to the capabilities of expression and questioning that tools can exert, finding in them the possibility of long-lasting values in industrial products.
Book Review T. Rothengatter & R.D. Huguenin (Eds.) Traffic and transport psychology: Theory and applications. Amsterdam, Elsevier

The book is the selected proceedings of the second international conference of traffic and transport psychology (TTP) held in Bern, Switzerland, in 2000. The first conference took place 1996 in Valencia, Spain, the third 2004 in Nottingham, UK (Rothengatter & CarbobellVaja, 1997; Underwood, 2005). A casual look at the three volumes from the conferences indicates that their structure and contents are similar. In the volume under review, keynote lectures, selected papers and poster presentations are included. A first part contains an introduction by the editors and three chapters addressing the general issue of theory in a field of applied research such as TTP. The remaining parts are dominated by reported empirical studies with some interspersed overview, conceptual, or discussion chapters. Truthfully representing current TTP research, these include road user characteristics (cognition and performance, social and differential psychology, and impairment), road safety (driver information and support systems, enforcement and training, and selection and rehabilitation), and mobility and the environment
On the Convergence of Ionospheric Constrained Precise Point Positioning (IC-PPP) Based on Undifferential Uncombined Raw GNSS Observations

Precise Point Positioning (PPP) has become a very hot topic in GNSS research and applications. However, it usually takes about several tens of minutes in order to obtain positions with better than 10 cm accuracy. This prevents PPP from being widely used in real-time kinematic positioning services, therefore, a large effort has been made to tackle the convergence problem. One of the recent approaches is the ionospheric delay constrained precise point positioning (IC-PPP) that uses the spatial and temporal characteristics of ionospheric delays and also delays from an a priori model. In this paper, the impact of the quality of ionospheric models on the convergence of IC-PPP is evaluated using the IGS global ionospheric map (GIM) updated every two hours and a regional satellite-specific correction model. Furthermore, the effect of the receiver differential code bias (DCB) is investigated by comparing the convergence time for IC-PPP with and without estimation of the DCB parameter. From the result of processing a large amount of data, on the one hand, the quality of the a priori ionosphere delays plays a very important role in IC-PPP convergence. Generally, regional dense GNSS networks can provide more precise ionosphere delays than GIM and can consequently reduce the convergence time. On the other hand, ignoring the receiver DCB may considerably extend its convergence, and the larger the DCB, the longer the convergence time. Estimating receiver DCB in IC-PPP is a proper way to overcome this problem. Therefore, current IC-PPP should be enhanced by estimating receiver DCB and employing regional satellite-specific ionospheric correction models in order to speed up its convergence for more practical applications.
The Role Behavioral of Activation and Inhibition in Explaining Adolescents’ Game Use and Game Engagement Levels

According to Gray’s reinforcement sensitivity theory, variations in the functioning of two neuropsychological systems, the behavioral approach (BAS) and inhibition (BIS) system, can result in individual differences in personality. Several studies have looked at associations between personality and media use but media research integrating BAS and BIS is scarce. The current cross-sectional survey study (n = 1016) representative for Belgian adolescents investigated associations between BAS and BIS and game use and game engagement in adolescents. Results showed that BAS was positively associated with playing both violent and nonviolent games. BIS was negatively associated with violent game use while it was positively associated with nonviolent games. Also, BAS was positively associated with game engagement. No association was found between BIS and game engagement. Game engagement was shown to mediate the relationship between BAS and playing both violent and nonviolent games. Based on these results, the present study argues that integrating the reinforcement sensitivity theory in media research makes an important contribution to the understanding of the link between personality and game engagement and game use.
Cyclostationary spectrum sensing for Cognitive Radio and multiantenna systems

In this paper it is shown that cyclostationary spectrum sensing for Cognitive Radio networks, applying multiple cyclic frequencies for single user detection can be interpreted in terms of optimal incoherent diversity addition for "virtual diversity branches" or SIMO radar. This approach allows proposing, by analogy to diversity combining, suboptimal algorithms which can provide near optimal characteristics for the Neyman-Pearson Test (NPT). The analysis is based on the Generalized Gaussian (Klovsky-Middleton) Channel Model, which allows obtaining the above mention NPT characteristics: probability of misdetection (PM) and probability of false alarm (Pfa) in the most general way. Some quasi-optimum algorithms such as energetic receiver and selection addition algorithm are analyzed and their comparison with the noise immunity properties (Receiver Operational Characteristics-ROC) of the optimum approach is provided as well.
Genetic Diversity and Ancestral Relationships of Red Junglefowls and Domestic Chickens in Southeast

In the present study, we have explored the genetic relationships between red junglefowls and domestic chickens in Southeast Asia by using single nucleotide polymorphism (SNP) markers. We genotyped 475 individuals from 17 populations of red junglefowls (4 subspecies, n=39), native chickens (10 populations, n=346) and commercial breeds (3 breeds, n=90) using PCR-RFLP for the 98 autosomal SNP markers. The genotyping results showed that average heterozygosity was 0.225±0.077 for red junglefowl, 0.272±0.009 for native chickens, and 0.211±0.037 for commercial breeds of chickens. The resultant neighbor-joining (NJ) tree with three distinct clusters corresponds to red junglefowls, native chickens and commercial breeds. The subspecies of red junglefowl was clustered into one clade and more closely related to native chickens than the commercial lines. Furthermore, the results of the population structure analysis suggested that the 17 populations appear to be derived from 11 genetic populations (K= 11). Among the domestic chickens, the NJ tree and genetic structure analysis revealed that Thailand native chickens was the most ancestral group of all chickens. These findings provide molecular evidence supporting the theory that the original domestication event occurred in Thailand. They also provide additional clustering information to classify red junglefowls and domestic chickens.
THINKER - Entity Linking System for Turkish Language

Entity linking is one of the problems to be handled in order to process natural language and to enrich the existing unstructured text with metadata. The generation of assignments between knowledge base entities and lexical units is called entity linking. Although a number of systems have been proposed for linking entity mentions in various languages, there is currently no publicly available entity linking system specific to the Turkish language. This paper presents a novel entity linking system—THINKER - for linking Turkish content with entities defined in the Turkish dictionary (tdk.gov.tr) or Turkish Wikipedia (tr.wikipedia.org). Specifically, we first propose a novel machine learning based entity detection algorithm for the Turkish language. Then, we propose a collective disambiguation algorithm which utilizes a set of metrics for the linking task and, which is optimized using a genetic algorithm. The effectiveness of THINKER is validated empirically over generated data sets. The experimental results show that THINKER outperformed the state-of-the-art cross-lingual and multilingual entity linking systems in the literature. High entity linking performance (74.81 percent F1 score) is achieved by extending previous methods with some features specific to Turkish language and by developing a novel method that can learn better representations of entity embeddings.
Reliability and Factorial Validity of Non-Specific and Tennis-Specific Pre-Planned Agility Tests; Preliminary Analysis

Abstract Agility is an important quality in tennis, yet there is an evident lack of studies focussing on the applicability of tennis-specific agility performances and comparing them to equivalent non-specific agility performances. The aim of this study was to evaluate the reliability and factorial validity of three tests of pre-planned agility, performed in specific (with a tennis racquet) and non-specific (without a tennis racquet) conditions. The sample consisted of 33 tennis players (13 males and 20 females; age: 18.3 ± 1.1 years and 18.6 ± 1.3 years; body height: 185.4 ± 51 cm and 169.3 ± 4.2 cm, 74.0 ± 4.4 kg and 61.2 ± 3.1 kg, respectively). The variables comprised three agility tests: a 20-yard test, a T-test and the Illinois test, all performed in both specific and non-specific conditions. Between-subject and within-subject reliability were found to be high (Cronbach Alpha: 0.93 to 0.98; Coefficient of Variation: 3 to 8%), with better within-subject reliability and stability of the measurement for specific tests. Pearson’s product moment correlations between the non-specific and specific agility performances were high (r ≥0.84), while factor analysis extracted only one significant latent dimension on the basis of the Guttman-Kaiser criterion. The results of the 20-yard test were better when the test was conducted in the specific conditions (t-test = 2.66; p < 0.05). For the Illinois test, superior results were recorded in the non-specific conditions (t-test = 2.96; p < 0.05), which can be explained by the test duration (about 20 s) and non-specific locomotion forms such as rotational movements. Considering the findings of the present study, when testing tennis-specific pre-planned agility, we suggest using tests of short duration (less than 10 s) and sport-specific types of locomotion.
Self-adaptive hybrid Dynamic Power Management for many-core systems

We present a self-adaptive, hybrid Dynamic Power Management (DPM) scheme for many-core systems that targets concurrently executing applications with what we call “expanding” and “shrinking” resource allocations as, for example, in [13]–[15] [27]. To avoid frequent allocation and de-allocation, it enables applications to temporarily reserve their resources and to perform local power management decisions. The expand-to-shrink time periods and resource demands are predicted on-the-fly based on the application-specific knowledge and the monitored system information. Experimental results demonstrate up to 15%-40% Energy-Delay2 Product reduction of our scheme compared to state-of-the-art power management schemes like [4][8]. Self-adaptive local power-management decisions make our scheme scalable for large-scaled many-core systems as illustrated by numerous experiments.
A gaussian groundplan projection area model for evolving probabilistic classifiers

In this paper, an investigation of evolvable probabilistic classifiers is conducted, along with a thorough comparison between a classical Gaussian distance model, and the induction of Gaussian-to-circle projection model. The newly introduced model refers to a distance fitness measure, based on the projection of Gaussian distributions with geometric circles. The projection architecture aims to model and classify physical aggressive behaviours, by using biomechanical primitives. The primitives are being used to model the dynamics of the aggressive activities, by evolving biomechanical classifiers, which can discriminate between three behaviours and six actions. Both evolutionary models have shown strong discrimination performances on recognising the individual actions of each behaviour. From the comparison, the proposed model outperformed the classical one with three ensemble programs.
