Adverbial stance types in English

The present paper identifies various speech styles of English as marked by stance adver‐bials. By stance we mean the overt expression of an author's or speaker's attitudes, feelings, judgments, or commitment concerning the message. Adverbials are one of the primary lexical markers of stance in English, and we limit ourselves in this paper to adverbial marking of stance (the attitudinal and style disjuncts presented in Quirk, Green‐baum, Leech, & Svartvik, 1985). All occurrences of stance adverbials are identified in the LOB and London‐Lund corpora (410 texts of written and spoken British English), and each is analyzed in its sentential context to distinguish true markers of stance from adverbials that serve other functions (e.g., as manner adverbs). The adverbials marking stance are divided into six semantic categories, and the frequency of occurrence for each category in each text is computed. The six categories are labeled (1) honestly adverbials, (2) generally adverbials, (3) surely adverbials, (4) act.
Latent constructs of adjustment to aging and subjective age in Portugal and Romania: a comparative multiple correspondence analysis

Objective : To analyze the determinants of adjustment to aging (AtA) and subjective age (SA) identified by older adults and to investigate the differences of latent constructs that can work as major determinants in AtA and SA in an older Portuguese and Romanian population. Method : Measures were completed, including demographics and interviews. Complete data were available for 38 older adults aged between 74-90 years (M=80.6; SD = 5.4), from Portugal and Romenia. Data was subjected to content analysis. Representation of the associations and latent constructs were analyzed by a Multiple Correspondence Analysis (MCA). Results : The most prevalent response of the interviewed participants for determinants to AtA was ‘health status, physical and intellectual functioning’ (18.1%). ‘With apprehension’ and ‘good enough’ (both 27.0%) were identified as the most frequent SA responses. Findings showed a model for each nationality. AtA and SA for Portuguese elderly were explained by a three-factor model: ‘regardful’, ‘engaged’ and ‘conciliated’. A three-dimension model formed by ‘perseverant’, ‘congruent’ and ‘enjoyers’ was indicated as a best-fit solution for Romanian elderly. Conclusion : AtA and SA are strongly explained by increased likelihood of specific constructs in its definition. AtA is related to SA in older adults in both countries, although in different degree.
A Multi-Projector Calibration Method for Virtual Reality Simulators with Analytically Defined Screens

The geometric calibration of projectors is a demanding task, particularly for the industry of virtual reality simulators. Different methods have been developed during the last decades to retrieve the intrinsic and extrinsic parameters of projectors, most of them being based on planar homographies and some requiring an extended calibration process. The aim of our research work is to design a fast and user-friendly method to provide multi-projector calibration on analytically defined screens, where a sample is shown for a virtual reality Formula 1 simulator that has a cylindrical screen. The proposed method results from the combination of surveying, photogrammetry and image processing approaches, and has been designed by considering the spatial restrictions of virtual reality simulators. The method has been validated from a mathematical point of view, and the complete system—which is currently installed in a shopping mall in Spain—has been tested by different users.
Reliability of coral isotope records from the Western Pacific Warm Pool: A comparison using age‐optimized records

Stable isotope analysis of two separate corals from Nauru Island in the warm pool of the western tropical Pacific confirm that coral oxygen isotopes are a robust recorder of environmental variables. Coral delta(18)O faithfully records interannual variability even when strongly influenced by kinetic effects. Interannual to decadal variability of coral delta(13)C remains enigmatic; only one of the two corals exhibits the expected light-delta(13)C response in the interannual band. Coral delta(18)O from this region has a great similarity to global instrumental temperature records reflecting the impact of the Pacific warm pool and variations of the Indonesian Low in concert with El Nino-Southern Oscillation on global climate. Since 1896, coral delta(18)O has exhibited a cumulative decrease of 0.7 parts per thousand, which reflects a combination of warming and more frequent El Nino events (precipitation) affecting the surface waters of this region.
Recognition of Emotional Facial Expressions: The Role of Facial and Contextual Information in the Accuracy of Recognition

Recognition of emotional facial expressions is a central area in the psychology of emotion. This study presents two experiments. The first experiment analyzed recognition accuracy for basic emotions including happiness, anger, fear, sadness, surprise, and disgust. 30 pictures (5 for each emotion) were displayed to 96 participants to assess recognition accuracy. The results showed that recognition accuracy varied significantly across emotions. The second experiment analyzed the effects of contextual information on recognition accuracy. Information congruent and not congruent with a facial expression was displayed before presenting pictures of facial expressions. The results of the second experiment showed that congruent information improved facial expression recognition, whereas incongruent information impaired such recognition.
GeneXpert MTB/RIF Assay for the Diagnosis of Tuberculous Lymphadenitis on Concentrated Fine Needle Aspirates in High Tuberculosis Burden Settings

Introduction The diagnosis of tuberculous lymphadenitis (TBL) remains challenging. The routinely used methods (cytology and smear microscopy) have sub-optimal sensitivity. Recently, WHO recommends GeneXpert to be used as the initial diagnostic test in patients suspected of having extra-pulmonary tuberculosis (EPTB). However, this was a conditional recommendation due to very low-quality evidence available and more studies are needed. In this study we evaluated the performance of Xpert for the diagnosis of TBL on concentrated fine needle aspirates (FNA) in Southwest Ethiopia. Methods FNA was collected from presumptive TBL cases. Two smears were prepared from each aspirate and processed for cytology and conventional microscopy. The remaining aspirate was treated with N-acetyl-L-cysteine-NaOH and centrifuged for 15minutes at 3000g. The concentrated sediment was used for culture and Xpert test. Capilia TB-Neo test was used to differentiate M. tuberculosis complex (MTBC) from non-tuberculous mycobacteria (NTM). Composite bacteriological methods (culture and/or smear microscopy) were considered as a reference standard. Result Out of 143 enrolled suspects, 64.3% (92/143) were confirmed TBL cases by the composite reference standard (CRS). Xpert detected M. tuberculosis complex (MTBC) in 60.1% (86/143) of the presumptive TBL cases. The sensitivity of Xpert compared to CRS was 87.8% [95% CI: 81.0–94.5] and specificity 91.1% [95% CI: 82.8–99.4]. The sensitivity was 27.8% for smear microscopy and 80% for cytology compared to CRS. Cytology showed the lowest specificity (57.8%). Xpert was positive in 4 out of 45 culture- and smear-negative cases. Among 47 cytomorphologically non-TBL cases, 15 were positive on Xpert. More than half of Xpert-positive cases were in the range of very low cut-off threshold values (28<Ct<38). Resistance to rifampicin was identified in 4.7% (4/86) of Xpert-positive cases. Conclusion Xpert test showed a high sensitivity and specificity for the diagnosis of TBL on concentrated FNA samples. In addition, Xpert offered rapid detection of rifampicin-resistant M. tuberculosis strains from lymph node aspirates.
Long Term Results of Unicondylar Fractures of the Femur

Twenty-four unicondylar fractures of the distal femur were treated at the Trauma Center “Bergmannsheil,” University of Bochum, Germany, between 1981 and 1990. All patients sustained their injuries from severe direct trauma. There were 16 lateral condylar fractures, five medial condylar fractures, and three tangential posterior (“Hoffa-type”) fractures. Twenty-three closed injuries and one grade IIIB open fracture are included. Nine patients (37.5%) sustained concomitant injuries to the skeleton. All fractures were treated with open reduction and internal fixation with screws within 8 h of admission. Postoperative management consisted of early continuous passive motion and minimal weight bearing for 6–8 weeks progressing to full weight bearing. The mean follow-up was 62 months (24–120). The therapeutic outcome (clinical result, radiographs) was rated by the Neer score. Twenty patients were rated excellent, three achieved satisfactory results, and one had an unsatisfactory result. All patients without an excellent outcome had accompanying injuries. Open reduction and internal screw fixation of unicondylar femur fractures provides overall excellent long-term results. The therapeutic outcome is significantly affected by associated injuries of the skeleton.
Automatic interface optimization through random exploration of available elements

The Keystroke-Level Model (KLM) is an interface evaluation method that use as metric the time needed to perform an executed action to complete a given task. The description used in KLM is very similar to the formalism that Markov Decision Process (MDP) uses to describe a domain, in which an artificial agent must perform a sequence of actions in order to solve a problem. This work presents a way to model a user's interaction with an interface using MDP combined with KLM in order to optimize a set of parameters and find the best set of interface components for a user. Results show that by changing the metrics of the KLM, the MDP finds different solutions that may be combined to generate an interface tailored for a given user.
Development of axial flux permanent magnet generator for direct driven micro wind turbine

This paper presents the development of Axial Flux Permanent Magnet Generator to be used for wind turbines in the range below 5 kW power applications. The proposed generator that is to be directly coupled to the wind turbine, unlocks the potential for energy harvesting due to its outstanding merits such as high efficiency, low cogging torque, high power density and ease of manufacturing and assembly. In this paper, the analytical model for generator sizing is presented, main parameters to meet the requirements are defined. The generator is also modeled using Matlab/Simulink to predict its performance under certain operating conditions. In addition, generator model and simulation results are validated via experimental tests. The preliminary experimental results showed a good match with the simulation results hence demonstrate the concrete benefits of utilizing the axial flux permanent magnet generator in scavenging energy to generate electrical power from micro wind turbines.
Gaze perception in social anxiety and social anxiety disorder

Clinical observations suggest abnormal gaze perception to be an important indicator of social anxiety disorder (SAD). Experimental research has yet paid relatively little attention to the study of gaze perception in SAD. In this article we first discuss gaze perception in healthy human beings before reviewing self-referential and threat-related biases of gaze perception in clinical and non-clinical socially anxious samples. Relative to controls, socially anxious individuals exhibit an enhanced self-directed perception of gaze directions and demonstrate a pronounced fear of direct eye contact, though findings are less consistent regarding the avoidance of mutual gaze in SAD. Prospects for future research and clinical implications are discussed.
Consequences of cytotoxic T lymphocyte interaction with major histocompatibility complex class I-expressing neurons in vivo

Neurons have evolved strategies to evade immune surveillance that include an inability to synthesize the heavy chain of the class I major histocompatibility complex (MHC), proteins that are necessary for cytotoxic T lymphocyte (CTL) recognition of target cells. Multiple viruses have taken advantage of the lack of CTL-mediated recognition and killing of neurons by establishing persistent neuronal infections and thereby escaping attack by antiviral CTL. We have expressed a class I MHC molecule (Db) in neurons of transgenic mice using the neuron- specific enolase (NSE) promoter to determine the pathogenic consequences of CTL recognition of virally infected, MHC-expressing central nervous system (CNS) neurons. The NSE-Db transgene was expressed in H-2b founder mice, and transgene-derived messenger RNA was detected by reverse transcriptase-polymerase chain reaction in transgenic brains from several lines. Purified primary neurons from transgenic but not from nontransgenic mice adhered to coverslips coated with a conformation-dependent monoclonal antibody directed against the Dv molecule and presented viral peptide to CTL in an MHC-restricted manner, indicating that the Db molecule was expressed on transgenic neurons in a functional form. Transgenic mice infected with the neurotropic lymphocytic choriomeningitis virus (LCMV) and given anti- LCMV, MHC-restricted CTL displayed a high morbidity and mortality when compared with controls receiving MHC-mismatched CTL or expressing alternative transgenes. After CTL transfer, transgenic brains showed an increased number of CD8+ cells compared with nontransgenic controls as well as an increased rate of clearance of infectious virus from the CNS. Additionally, an increase in blood-brain barrier permeability was detected during viral clearance in NSE-Db transgenic mice and lasted several months after clearance of virus from neurons. In contrast, LCMV- infected, nontransgenic littermates and mice expressing other gene products from the NSE promoter showed no CNS disease, no increased intraparenchymal CTL, and no blood-brain barrier damage after the adoptive transfer of antiviral CTL. Our study indicates that viral infections and CTL-CNS interactions may induce blood-brain barrier disruptions and neurologic disease by a "hit-and-run" mechanism, triggering a cascade of pathogenic events that proceeds in the absence of continual viral stimulation.
Calibration of input-match and its center frequency for an inductively degenerated low noise amplifier

All RF circuit is exposed to process variations and parasitic elements, which can degrade significantly the input match and deviate its center frequency. This paper proposes a new technique to calibrate the input match and its center frequency for 2.45 GHz CMOS inductively degenerated low noise amplifier (LNA). This technique allows center frequency deviation compensation and corrects the shift of the input match quality without degrading the others characteristics of the LNA.
Consumers, Producers and Practices

The idea that artifacts are acquired and used in the course of accomplishing social practices has important implications for theories of consumption and innovation. From this point of view, it is not enough to show that goods are symbolically and materially positioned, mediated and filtered through existing cultures and conventions. Twisting the problem around, the further challenge is to explain how practices change and with what consequence for the forms of consumption they entail. In this article, we suggest that new practices like Nordic walking, a form of ‘speed walking’ with two sticks, arise through the active and ongoing integration of images, artifacts and forms of competence, a process in which both consumers and producers are involved. While it makes sense to see Nordic walking as a situated social practice, such a view makes it difficult to explain its growing popularity in countries as varied as Japan, Norway and the USA. In addressing this issue, we conclude that practices and associated cultures of consumption are always ‘homegrown’. Necessary and sometimes novel ingredients (including images and artifacts) may circulate widely, but they are always pieced together in a manner that is informed by previous and related practice. What looks like the diffusion of Nordic walking is therefore better understood as its successive, but necessarily localized, (re)invention. In developing this argument, we explore some of the consequences of conceptualizing consumption and consumer culture as the outcome of meaningful social practice.
Engaging Chinese ideas through Australian education research: using chéngyŭ to connect intellectual projects across ‘peripheral’ nations

The increasing number of higher degree research students from China in the universities of multicultural Australia as elsewhere has added to the mounting interest in pedagogies of postgraduate supervision. This paper explores the proposition that efforts to articulate Chinese ideas through research in, for and about Australia have to negotiate positions that would allow or disallow their embedding in the Australian education research community. To do so, the literature on higher degree research supervision in multicultural contexts is reviewed. Then the co-operative approach used to document a higher degree research student's experiences of integrating knowledge from her Chinese intellectual heritage into her research is explained. The third section illustrates a research intervention whereby Chinese knowledge was articulated through research in, for and about teacher education in Australia. The fourth section presents evidence of three different responses to this move to embed Chinese ideas in the Australian education research community. Specifically, the responses of Australian academics to her use of chéngyŭ to theorise her evidence is explored.
On Representing Objects with a Language of Sentience1

In his book A Theory of Sentience, Austen Clark argues that the content of sensory representations can be expressed as sentences constructed from a language of sentience. Such sentences specify that a determinate feature obtains in a particular space-time region, but the language's limited vocabulary prohibits the sentences from referring or attributing features to objects. In this paper, I show that this view is flawed in at least two ways. First, if sensation has the capacities that Clark and others attribute to it, then the vocabulary of sense extends further than he supposes, and a limited language of sentience cannot justify a prohibition of object representation within sentience. Second, even if the language of sentience is as impoverished as he claims, and thus even if the representational capacity of sentience is correspondingly limited, object individuation can plausibly occur at the level of sensation. In the course of defusing Clark's major argument for an “object-less” theory of sentience, I offer reasons to believe both that sensory representations can be impressively sophisticated in what they say about the world, and that object representations can be surprisingly basic.
A vertical-cavity surface-emitting laser appliqued to a 0.8-μm NMOS driver

An optoelectronic integrated circuit (OEIC) composed of a vertical-cavity surface-emitting laser (VCSEL) appliqued to an NMOS drive circuit was fabricated to form an optical link from the CMOS chip. A custom NMOS circuit was designed and fabricated through the MOSIS foundry service in a standard 0.8-/spl mu/m CMOS process. InGaAs quantum-well VCSELs were grown, fabricated and tested on an n-type GaAs substrate. Next, the VCSELs underwent a substrate removal technique and were appliqued to the NMOS circuitry. The OEIC was tested at the chip level and showed an electrical to optical conversion efficiency of 1.09 mW/V. Modulation results are also discussed.
Elasto-capillary thinning and breakup of model elastic liquids

We study the elasto-capillary self-thinning and ultimate breakup of three polystyrene-based ideal elastic fluids by measuring the evolution in the filament diameter as slender viscoelastic threads neck and eventually break. We examine the dependence of the transient diameter profile and the time to breakup on the molecular weight, and compare the observations with simple theories for breakup of slender viscoelastic filaments. The evolution of the transient diameter profile predicted by a multimode FENE-P model quantitatively matches the data provided the initial stresses in the filament are taken into account. Finally, we show how the transient uniaxial extensional viscosity of a dilute polymer solution can be estimated from the evolution in the diameter of the necking filament. The resulting “apparent extensional viscosity” profiles are compared with similar results obtained from a filament stretching rheometer. Both transient profiles approach the same value for the steady state extensional viscosity, which increases with molecular weight in agreement with the Rouse–Zimm theory. The apparent discrepancy in the growth rate of the two transient curves can be quantitatively explained by examining the effective stretch rate in each configuration. Filament thinning studies and filament stretching experiments thus form complementary experiments that lead to consistent measures of the transient extensional viscosity of a given test fluid.
Model uncertainty in the ecosystem approach to fisheries

Fisheries scientists habitually consider uncertainty in parameter values, but often neglect uncertainty about model structure, an issue of increasing importance as ecosystem models are devised to support the move to an ecosystem approach to fisheries (EAF). This paper sets out pragmatic approaches with which to account for uncertainties in model structure and we review current ways of dealing with this issue in fisheries and other disciplines. All involve considering a set of alternative models representing different structural assumptions, but differ in how those models are used. The models can be asked to identify bounds on possible outcomes, find management actions that will perform adequately irrespective of the true model, find management actions that best achieve one or more objectives given weights assigned to each model, or formalize hypotheses for evaluation through experimentation. Data availability is likely to limit the use of approaches that involve weighting alternative models in an ecosystem setting, and the cost of experimentation is likely to limit its use. Practical implementation of an EAF should therefore be based on management approaches that acknowledge the uncertainty inherent in model predictions and are robust to it. Model results must be presented in ways that represent the risks and trade-offs associated with alternative actions and the degree of uncertainty in predictions. This presentation should not disguise the fact that, in many cases, estimates of model uncertainty may be based on subjective criteria. The problem of model uncertainty is far from unique to fisheries, and a dialogue among fisheries modellers and modellers from other scientific communities will therefore be helpful.
