Intermittent Locomotion Increases Endurance in a Gecko

Nocturnal geckos can actively forage at low temperatures. A low minimum cost of locomotion allows greater sustainable speeds by partially offsetting the decrease in maximal oxygen consumption (V̇o2max) associated with low nocturnal temperatures. The nocturnality hypothesis (Autumn et al. 1997) proposes that the reduced cost of continuous locomotion is a shared, derived characteristic that increases the capacity to sustain locomotion at low temperatures. Yet many lizards move intermittently at speeds exceeding those that elicit V̇o2max. We exercised the frog‐eyed gecko, Teratoscincus przewalskii, continuously and intermittently on a treadmill. At an exercise speed of 0.90 km h−1 (270% maximum aerobic speed), lizards alternating a 15‐s exercise period with a 30‐s pause period exhibited a 1.7‐fold increase in distance capacity (total distance traveled before fatigue) compared with lizards exercised continuously at the same average speed (0.30 km h−1). The average aerobic cost of intermittent exercise was not significantly different from V̇o2max. Locomoting intermittently could augment the increase in endurance resulting from the low minimum cost of continuous locomotion in nocturnal geckos. Intermittent behavior could increase the endurance of lizard movement in general.
Cultivating a Culture of Thinking in Museums

Abstract During the brief time students come together for a group tour, museum educators have the opportunity to create a culture of thinking: a place where the group's collective as well as individual thinking is valued, made visible, and actively promoted as part of the ongoing experience of all group members. Creating such a culture is facilitated by understanding the dynamic context of group learning and the ways in which groups enculturate students into patterns of thinking. This article describes eight cultural forces found to shape the culture of group learning in classroom settings, applies this framework to tour observations conducted at three different museums, and explores ways that museum educators might best leverage these forces to cultivate a culture of thinking when conducting school group tours.
Social Exchanges Within Organizations and Work Outcomes

Social exchange research has focused primarily on employee relationships with supervisors and with the organization to explain employee in-role and extra-role behaviors. This article extends the understanding of social exchange by exploring two additional exchanges (employee relationships with top management and with employees in other work areas) and examine all four social exchanges’ effects on work behaviors. It also extends notions of employee performance to include employee involvement in organizational improvement efforts. Data collected in a field study of 129 supervisor-subordinate dyads suggest that local (interpersonal exchanges with supervisors and colleagues in other work areas) and global (exchanges with top management and the organization)foci have different effects on work performance and that local social exchanges have a greater influence on work outcomes than global social exchanges.
Determinants and Impact of Sovereign Credit Ratings

The authors conduct the first systematic analysis of the determinants and impact of the sovereign credit ratings assigned by the two leading U.S. agencies, Moody's Investor Services and Standard and Poor's. Of the large number of criteria used by the two agencies, six factors appear to play an important role in determining a country's credit rating: per capita income, GDP growth, inflation, external debt, level of economic development, and default history. In addition, the authors find that sovereign ratings influence market yields--particularly those on non-investment-grade issues--independently of any correlation with publicly available information.
THE MAGNETOSPHERE OF THE ULTRACOOL DWARF DENIS 1048−3956

Ultracool dwarfs, the least-massive contributors to the stellar mass function, exhibit striking magnetic properties that are inconsistent with trends for more massive stars. Here, we present the widest-band radio observations to date of an ultracool dwarf, DENIS-P J104814.9−395604, in four 2 GHz bandwidths between wavelengths of 1 cm and 10 cm. These data were obtained with the Australia Telescope Compact Array using the new Compact Array Broadband Backend instrument. We detected a stable negatively sloped power-law spectrum in total intensity, with spectral index α = 1.71 ± 0.09. Circular polarization fractions between 0.25 and 0.4 were found at the low-frequency end of our detection band. We interpret these results as indicative of gyrosynchrotron emission. We suggest that the radio emission originates from beyond the corotation radius, RC, of the star. Adopting this model, we find RC between 1.2 R* and 2.9 R*, and a non-thermal electron density and magnetic field strength between 105 and 107.2 cm−3 and between 70 and 260 G, respectively, at RC. The model accounts for the violation of the Güdel–Benz relation between X-ray and radio luminosities of low-mass stars by DENIS-P J104814.9−395604.
The Contribution of Linguistic Features to Automatic Machine Translation Evaluation

A number of approaches to Automatic MT Evaluation based on deep linguistic knowledge have been suggested. However, n-gram based metrics are still today the dominant approach. The main reason is that the advantages of employing deeper linguistic information have not been clarified yet. In this work, we propose a novel approach for meta-evaluation of MT evaluation metrics, since correlation cofficient against human judges do not reveal details about the advantages and disadvantages of particular metrics. We then use this approach to investigate the benefits of introducing linguistic features into evaluation metrics. Overall, our experiments show that (i) both lexical and linguistic metrics present complementary advantages and (ii) combining both kinds of metrics yields the most robust metaevaluation performance.
Homotaurine Metabolized to 3-Sulfopropanoate in Cupriavidus necator H16: Enzymes and Genes in a Patchwork Pathway

ABSTRACT Homotaurine (3-aminopropanesulfonate), a natural product and an analogue of GABA (4-aminobutyrate), was found to be a sole source of nitrogen for Cupriavidus necator (Ralstonia eutropha) H16, whose genome sequence is known. Homotaurine nitrogen was assimilated into cell material, and the quantitative fate of the organosulfonate was sulfopropanoate, which was recovered in the growth medium. The first scalar reaction was shown to be inducible homotaurine:2-oxoglutarate aminotransferase, which released 3-sulfopropanal from homotaurine. This aminotransferase was purified to homogeneity and characterized. Peptide mass fingerprinting yielded locus tag H16_B0981, which was annotated gabT, for GABA transaminase (EC 2.6.1.19). Inducible, NAD(P)+-coupled 3-sulfopropanal dehydrogenase, which yielded 3-sulfopropanoate from 3-sulfopropanal, was also purified and characterized. Peptide mass fingerprinting yielded locus tag H16_B0982, which was annotated gabD1, for succinate-semialdehyde dehydrogenase (EC 1.2.1.16). GabT and GabD1 were each induced during growth with GABA, and cotranscription of gabTD was observed. In other organisms, regulator GabC or GabR is encoded contiguous with gabTD: candidate GabR′ was found in strain H16 and in many other organisms. An orthologue of the GABA permease (GabP), established in Escherichia coli, is present at H16_B1890, and it was transcribed constitutively. We presume that GabR′PTD are responsible for the inducible metabolism of homotaurine to intracellular 3-sulfopropanoate. The nature of the exporter of this highly charged compound was unclear until we realized from the sodium dodecyl sulfate-polyacrylamide gel electrophoresis data that sulfoacetaldehyde acetyltransferase (EC 2.3.3.15; H16_B1872) was strongly induced during growth with homotaurine and inferred that the sulfite exporter encoded at the end of the gene cluster (H16_B1874) has a broad substrate range that includes 3-sulfopropanoate.
Sepsis during pregnancy or the postpartum period

Sepsis is an important cause of maternal morbidity and mortality worldwide. Early recognition and timely treatment are the key to ensuring a favourable outcome. This article reviews recent literature about definitions, pathophysiology, incidence, diagnosis, management, treatment, prevention and outcome of sepsis during pregnancy and the postpartum period.
The Canadian Legal Profession

This article seeks to weave together the limited information available on the legal professions of the Canadian provinces. Following the same general format as the other comparative studies in this series, it also offers several critical observations of special interest to readers in the United States, whose experience the Canadian bar so closely tracks. The phenomenon of stratification—familiar to American observers—is clearly visible in the Canadian legal profession. Combined with other centrifugal forces, it threatens the unity of a profession which, until recently, has managed to preserve a high degree of cohesion in training, ideology, and institutional structures. On the other hand, in certain respects, the Canadian experience seems to differ from that of the United States, especially in the strength and peculiar structure of publicly funded legal aid schemes, in the profession's continuing formal autonomy and relative immunity from public regulation, and in its long-lasting attachment to apprenticeship as a necessary stage in professional formation. These and other convergences and divergences between the two countries raise questions of general significance: To what extent do the similarities between Canada and the United States verify the assumption implicit in the theoretical literature (principally Abel, Freidson, and Larson) that there is an empirical referent for something called legal professionalism? And to what extent do the differences suggest that containing societies contribute distinctive characteristics to their legal professions, whose qualities are therefore highly contingent?
Vardenafil, a new phosphodiesterase type 5 inhibitor, in the treatment of erectile dysfunction in men with diabetes: a multicenter double-blind placebo-controlled fixed-dose study.

OBJECTIVE This study evaluated the efficacy and safety of vardenafil treatment for erectile dysfunction (ED) in men with diabetes. RESEARCH DESIGN AND METHODS In this prospective multicenter double-blind placebo-controlled fixed-dose parallel-group phase III trial, 452 patients with diabetes (type 1 or type 2) and ED were randomized to take 10 or 20 mg vardenafil or placebo as needed for 12 weeks. Efficacy responses were assessed by International Index of Erectile Function domain scores, rates of vaginal penetration and successful intercourse, and a global assessment question (GAQ) about erection improvement during the previous 4 weeks. RESULTS After 12 weeks of treatment, a dose-dependent (P = 0.02) improvement in erections was noted for the GAQ, with 57 and 72% of men taking 10 mg or 20 mg vardenafil, respectively, reporting improved erections, in contrast to 13% after taking placebo (P < 0.0001). For the erectile function domain, dose-dependent (P = 0.03) final scores for the 10- and 20-mg dose were 17.1 and 19.0 compared with 12.6 for placebo (P < 0.0001). Both vardenafil doses significantly enhanced the rates of successful penetration (P < 0.0001) and successful intercourse (P < 0.0001) compared with placebo. Vardenafil treatment was effective in increasing intercourse success rates at all levels of baseline ED severity, at each level of plasma HbA(1c), and for type 1 and 2 diabetes. Treatment-emergent adverse events were primarily mild to moderate headache (<or=13%), flushing (<or=10%), and rhinitis (<or=10%). CONCLUSIONS Vardenafil statistically improved erectile function and was generally well tolerated in these diabetic patients with ED.
Methods for determining the accuracy of radiostereometric analysis (RSA)

The problem of determining the noise level in any measuring system remains urgent. Radiostereometric analysis (RSA) is a radiographic system of unique accuracy which has applications in areas where minute motions or no motion at all occurs. Examples are micromotion between endoprostheses and bone and in fracture healing. We have determined the accuracy of the RSA system as applied to a clinical series of spinal fusions, where the conditions for RSA were not optimal. Using the usual test-retest methodology on a phantom, we showed that its accuracy can be grossly overestimated in the individual case. We found considerable variations in the accuracy in the individual case, depending on the rigid-body configuration. The overall accuracy, expressed as 3-D "vectors" for rotation and translation, respectively, correlated with the condition number, a method for characterizing the marker configuration. Indeed, the condition number explained as much as 92% of the variation in overall rotation. This condition number, however, cannot be used to analyze the accuracy of one degree of freedom of rotation alone. Mathematical simulation of the accuracy in the individual case of the individual dimension, using in-house software, showed that the accuracy (95% confidence) varied between 0.4 and 4.6 degrees of rotation about the transverse axis, corresponding to a clinical stress series of extension and flexion.
Factors Influencing Household Uptake of Improved Solid Fuel Stoves in Low- and Middle-Income Countries: A Qualitative Systematic Review

Household burning of solid fuels in traditional stoves is detrimental to health, the environment and development. A range of improved solid fuel stoves (IS) are available but little is known about successful approaches to dissemination. This qualitative systematic review aimed to identify factors that influence household uptake of IS in low- and middle-income countries. Extensive searches were carried out and studies were screened and extracted using established systematic review methods. Fourteen qualitative studies from Asia, Africa and Latin-America met the inclusion criteria. Thematic synthesis was used to synthesise data and findings are presented under seven framework domains. Findings relate to user and stakeholder perceptions and highlight the importance of cost, good stove design, fuel and time savings, health benefits, being able to cook traditional dishes and cleanliness in relation to uptake. Creating demand, appropriate approaches to business, and community involvement, are also discussed. Achieving and sustaining uptake is complex and requires consideration of a broad range of factors, which operate at household, community, regional and national levels. Initiatives aimed at IS scale up should include quantitative evaluations of effectiveness, supplemented with qualitative studies to assess factors affecting uptake, with an equity focus.
Squamous cell carcinoma with necrotizing scleritis.

PURPOSE To report on a case of limbal squamous cell carcinoma (SCC) with necrotizing scleritis in a young, previously healthy, white Australian male. METHODS A 31-year-old man presented with a left limbal lesion intermittently causing a red eye and foreign body sensation. He had enjoyed surfing for many years. Repeat HIV tests were negative and the lesion was biopsied. RESULTS Biopsy showed a well-differentiated SCC apparently arising in an intra-epithelial (in situ) carcinoma of the conjunctiva. The lesion was excised and a corneoscleral graft repair was performed. CONCLUSION The present case highlights the potential for a significant increase in the prevalence of ocular surface neoplasia in healthy young people who have had excessive UV-B exposure.
Real-time processing in reading sentence comprehension for normal adult individuals and persons with aphasia

Background: Persons with aphasia (PWA) have shown difficulties in integrating linguistic materials over time and distance in sentence processing. However, few studies have investigated sentence-processing difficulties among PWA as reflected in online processing measures. Furthermore, relatively few studies have examined the online processing of syntactically simple but computationally demanding sentences among PWA. Such sentences are important from the perspective of resource-related theories of aphasic language deficits, which predict that such sentences should be challenging for PWA even if the syntactic structures involved are not. Aims: The purpose of the study was to investigate the sentence-level online reading times of normal adult individuals (NAI) and PWA by word category and as a function of adjective padding. It was assumed that head nouns entail greater processing costs than determiners because they represent the point at which integration of material within a noun phrase must take place. It was also assumed that increasing adjectival padding within a noun phrase requires more integration and creates greater processing costs. Methods & Procedures: A total of 30 NAI and 30 PWA participated in the current study. Sentence stimuli were obtained from the Computerised Revised Token Test (CRTT) (McNeil et al., 2008). Sentences were presented using a non-cumulative (Word Fade = WF) self-paced word-by-word reading method (CRTT-R-WF). Reading times for the determiners and the correct nouns were analysed. Outcomes & Results: Both groups showed significantly longer reading times for the nouns than for determiners and in two-adjective than in one-adjective conditions. Furthermore, the reading times for the two-adjective condition were significantly longer than the one-adjective condition for nouns but not determiners across the groups. The PWA exhibited significantly longer overall reading times, as well as significantly longer reading times on the nouns than the NAI. Conclusions: Increased linguistic integration costs—imposed by greater amounts of material to be integrated, and appearing at the point where integration must take place—differentiated reading-time performance between the NAI and PWA participant groups. The PWA showed differentially longer online processing times for elements that imposed high integration costs. This difference appeared most dramatically when two adjectives intervened between the determiner and the head noun. The current results are consistent with resource-related hypotheses regarding aphasic language deficits, which suggest that PWA with limited control of processing resources should show differentially greater impairments in sentence processing as compared to NAI.
Elevated upper body position improves pregnancy-related OSA without impairing sleep quality or sleep architecture early after delivery.

BACKGROUND During pregnancy, upper airway resistance is increased, predisposing vulnerable women to pregnancy-related OSA. Elevation of the upper body increases upper airway cross-sectional area (CSA) and improves severity of OSA in a subgroup of nonpregnant patients (positional-dependent sleep apnea). We tested the hypothesis that elevated position of the upper body improves OSA early after delivery. METHODS Following institutional review board approval, we conducted a randomized, crossover study on two postpartum units of Massachusetts General Hospital. Women during the first 48 h after delivery were included. Polysomnography was performed in nonelevated and 45° elevated upper body position. Upper airway CSA was measured by acoustic pharyngometry in nonelevated, 45° elevated, and sitting body position. RESULTS Fifty-five patients were enrolled, and measurements of airway CSA obtained. Thirty patients completed polysomnography in both body positions. Elevation of the upper body significantly reduced apnea-hypopnea index (AHI) from 7.7 ± 2.2/h in nonelevated to 4.5 ± 1.4/h in 45° elevated upper body position (P = .031) during sleep. Moderate to severe OSA (AHI > 15/h) was diagnosed in 20% of postpartum patients and successfully treated by elevated body position in one-half of them. Total sleep time and sleep architecture were not affected by upper body elevation. Change from nonelevated to sitting position increased inspiratory upper airway CSA from 1.35 ± 0.1 cm2 to 1.54 ± 0.1 cm2 during wakefulness. Position-dependent increase in CSA and decrease in AHI were correlated (r = 0.42, P = .022). CONCLUSIONS Among early postpartum women, 45° upper body elevation increased upper airway CSA and mitigated sleep apnea. Elevated body position might improve respiratory safety in women early after delivery. TRIAL REGISTRY ClinicalTrials.gov; No.: NCT01719224; URL: www.clinicaltrials. gov.
The impact of epistemology on learning: A case study from introductory physics

We discuss a case study of the influence of epistemology on learning for a student in an introductory college physics course. An analysis of videotaped class work, written work, and interviews indicates that many of the student’s difficulties were epistemological in nature. Our primary goals are to show instructors and curriculum developers that a student’s personal epistemological stance—her ideas about knowledge and learning—can have a direct, causal influence on her learning of physics, and to describe a mechanism for this interaction. This influence exists even when research-based curriculum materials provide implicit epistemological support. For this reason, curriculum materials and teaching techniques could become more effective by explicitly attending to students’ epistemologies.
Automatic Assessment of Absolute Sentence Complexity

Lexically and syntactically simpler sentences result in shorter reading time and better understanding in many people. However, no reliable systems for automatic assessment of sentence complexity have been proposed so far. Instead, the assessment is usually done manually, requiring expert human annotators. To address this problem, we first define the sentence complexity assessment as a five-level classification task, and build a ‘gold standard’ dataset. Next, we propose robust systems for sentence complexity assessment, using a novel set of features based on leveraging lexical properties of freely available corpora, and investigate the impact of the feature type and corpus size on the classification performance.
Single‐sex classes in co‐educational schools

This research investigated social and academic outcomes from single‐sex classrooms in a Tasmanian coeducational government primary school. Interviews, observations and surveys formed the basis of the evidence. Teachers, parents and children reported positive benefits from the class organisation, but these differed according to gender. Staff identified increased confidence and higher self‐esteem among girls, whereas boys developed increased motivation and more commitment to schoolwork. Teachers and parents noted that boys’ accountability and self‐discipline improved. Teachers adopted different strategies from those used with mixed‐gender classes and gained higher levels of satisfaction from teaching, attributable to increased children’s time ‘on task’. Paradoxically, standardised school testing indicated no increase in academic achievements. However, there may be an extended lag between establishing changed social relationships and measurable academic outcomes, suggesting that if the new class structure is to achieve its full potential, it should be established early in primary school and continue to adolescence.
