Analogical reasoning skill acquisition with self-explanation in 7–8 year olds: Does feedback help?

This microgenetic study assessed the development of analogical reasoning on figural matrices by examining the additional effect of feedback on repeated practice including self-explanation. Participants were 39 children aged 7 to 8 years (M 7; 9 years) divided over self-explanation only and feedback plus self-explanation conditions based on randomised blocking. During six microgenetic sessions a multiple choice figural analogy task was administered. The results showed increased performance over time and an advantage of feedback for answer choice and most markedly for explanation quality. A trend was observed in which girls’ performance, regardless of feedback, and that of boys with feedback are comparable, yet boys without feedback did not perform quite as well. Further investigation of possible gender differences in the roles of self-explanation and feedback are advised. We recommend a combination of feedback and self-explanation to gain maximal advantage from these simple but useful approaches to supporting children’s learning processes.
Measurements of binary stars with coherent integration of NPOI data

In this paper we use coherently integrated visibilities (see separate paper in these proceedings1) to measure the properties of binary stars. We use only the phase of the complex visibility and not the amplitude. The reason for this is that amplitudes suffer from the calibration effect (the same for coherent and incoherent averages) and thus effectively provide lower accuracy measurements. We demonstrate that the baseline phase alone can be used to measure the separation, orientation and brightness ratio of a binary star, as a function of wavelength.

An accurate measurement of the baryonic Tully-Fisher relation with heavily gas-dominated ALFALFA galaxies

We use a sample of 97 galaxies selected from the Arecibo legacy fast ALFA (ALFALFA) 21 cm survey to make an accurate measurement of the baryonic Tully-Fisher relation (BTFR). These galaxies are specifically selected to be heavily gas-dominated (Mgas/M∗ ≳ 2.7) and to be oriented edge-on. The former property ensures that the error on the galactic baryonic mass is small, despite the large systematic uncertainty involved in galactic stellar mass estimates. The latter property means that rotational velocities can be derived directly from the width of the 21 cm emission line, without any need for inclination corrections. We measure a slope for the linewidth-based BTFR of α = 3.75 ± 0.11, a value that is somewhat steeper than (but in broad agreement with) previous literature results. The relation is remarkably tight, with almost all galaxies being located within a perpendicular distance of ± 0.1 dex from the best fit line. The low observational error budget for our sample enables us to establish that, despite its tightness, the measured linewidth-based BTFR has some small (i.e., non-zero) intrinsic scatter. We furthermore find a systematic difference in the BTFR of galaxies with "double-horned" 21 cm line profiles - suggestive of flat outer galactic rotation curves - and those with "peaked" profiles - suggestive of rising rotation curves. When we restrict our sample of galaxies to objects in the former category, we measure a slightly steeper slope of α = 4.13 ± 0.15. Overall, the high-accuracy measurement of the BTFR presented in this article is intended as a reliable observational benchmark against which to test theoretical expectations. Here we consider a representative set of semi-analytic models and hydrodynamic simulations in the lambda cold dark matter (ΛCDM) context, as well as modified Newtonian dynamics (MOND). In the near future, interferometric follow-up observations of several sample members will enable us to further refine the BTFR measurement, and make sharper comparisons with theoretical models.
Device level modeling challenges for circuit design methodology in presence of variability

CMOS technology scaling to decananometer range has raised the challenge to mitigate the impact of multi-scale process variations ranging from cm to atom-scale and acting as circuit yield detractors. Moreover, circuit applications in Ultra Low Power (ULP) range lead to MOSFET device operation in near threshold regime where it is well established that variability impact on DC/AC electrical characteristics dramatically increases. Variability mitigation techniques are part of process development. In addition, accurate circuit design methodologies are required to determine circuit performance margins versus specifications, and to develop circuit level variability mitigation/compensation techniques, to enable high yield and manufacturable products in presence of variability. In this context, we update device modeling requirements for circuit design, revisit device electrical characterization and compact modeling methodologies needed to support accurate circuit simulation throughout the design space. We focus on spatial variability components at local scale, including systematic layout effects and statistical variability. This approach is illustrated on UTBB FDSOI devices. Device modeling challenge for accurate circuit simulation in presence of variability is better identified.
The Munich Near-Infrared Cluster Survey (MUNICS) - V. The evolution of the rest-frame K-band and J-band galaxy luminosity functions to z ~ 0.7

We present spectroscopic follow-up observations of galaxies from the Munich Near-Infrared Cluster Survey (MUNICS). MUNICS is a wide-field medium-deep K'-band selected survey covering 1 square degree in the near-infrared K' and J pass-bands, and 0.35 square degrees in I, R, V, and - recently completed - B. The spectroscopic sample comprises observations of objects down to a limit of K'<17.5 in five survey fields (0.17 square degrees in total), and a sparsely selected deeper sample (K'<19.0) constructed in one of the survey patches (0.03 square degrees). Here we describe the selection procedure of objects for spectroscopic observations, the observations themselves, the data reduction, and the construction of the spectroscopic catalogue containing roughly 500 galaxies with secure redshifts. Furthermore we discuss global properties of the sample like its distribution in colour-redshift space, the accuracy of redshift determination, and the completeness function of the data. We derive the rest-frame K'-band luminosity function of galaxies at median redshifts of z = 0.2, z = 0.4, and z = 0.7. We find evidence for mild evolution of magnitudes (-0.70 mag) and number densities (35 per cent) to redshift one. Furthermore, we present the rest-frame J-band luminosity function of galaxies at these redshifts, the first determination of this quantity at higher redshifts, with a behaviour similar to the K-band luminosity function.
Overweight and Hypertension: A Review

The interrelationships between hypertension and obesity, two common and major health hazards, are reviewed. Comparisons of simultaneous intra-arterial and cuff blood pressure measurements indicate in general that the association between blood pressure and body weight is real and independent of arm circumference. Hypertension is more common among the obese than among the nonobese and, conversely, a significant proportion of hypertensive persons in the population are overweight. Obese hypertensive subjects experience a greater risk of coronary heart disease than the nonobese, and mortality rates for obese hypertensive persons are higher than for those with obesity alone or hypertension alone. Weight reduction has been shown to lower blood pressure, and it may bring about a more favorable prognosis in obese hypertensive persons. Possible mechanisms that may be responsible for the frequent association between obesity and hypertension have been discussed. Irrespective of the underlying pathophysiologic mechanisms, the adverse metabolic and hemodynamic effects of obesity upon hypertension impose an extra burden and strain on the circulatory system and compromise its functional adequacy. Although it is not precisely known to what extent weight reduction alone may be effective in controlling or preventing the lesser degrees of hypertension, the control of obesity should be an intrinsic part of any therapeutic or preventive antihypertensive regimen.
TweetGames: A framework for twitter-based collaborative social online games

Today social networks and microblogging services attract much attention and their importance and pervasion is constantly increasing. This trend is fostered by the increasing prevalence of mobile internet devices, which enable users to be online every time and everywhere. A popular kind of applications provided via social network platforms are games. While existing social network games basically realize common online game principles where each user controls a single game entity and acts on its own behalf, this paper presents a framework for the creation of a novel kind of social online games. The idea is to enable games where users do not act as individual game entities, instead groups of users control one game entity whose behavior emerges from the collective behavior of all group members. The framework is based on the microblogging service Twitter and users interact with the game via Twitter messages. These collaborative social online games are not just an innovative social network application, the intention of our framework is rather to provide a useful and powerful tool to complex social network researchers to study emergent and collective user behavior on a large scale utilizing the huge user base of a social network service like Twitter. In addition to presenting the idea of collaborative social online games along with the so-called TweetGame framework, this paper presents a sample application that has already been realized on top of this framework as proof of concept.
Compensation , and the Sell-Side Analyst Objective Function : An Empirical Analysis of Relational Incentives in the Investment-Research Industry

This paper investigates how sell-side analysts build and sustain their client networks; the economic gains to successfully managing this challenge; and the metrics through which these incentives are delivered. In a typical semiannual period, the average analyst supplies around 80 research notes and three reports; spends around one week brokering meetings between client investors and corporate managers; and holds approximately 750 private phone calls and 45 oneon-one meetings with client investors. Changes in these client-service actions explain approximately fifty percent of the intertemporal variation in broker votes, a mechanism used to measure the value that client investors ascribe to maintaining continued analyst relations, with the strongest sensitivity observed for widely disseminated, thematic, research reports known as whitepapers. Analysts’ client-service actions, however, explain relatively little intertemporal variation in commissions and broker share of trade execution in their covered stocks. Analysts who strengthen their client networks reap significant rewards and, consistent with the informativeness principle, we find these incentives to be delivered primarily through broker votes, not trades executed in analysts’ covered stocks. Our findings contribute to understanding of the job and objective functions of sell-side analysts and structure of relational incentives in the investment-research industry.
Evaluation of Absolute Cerebral Blood Flow by Laser-Doppler Scanning – Comparison with Hydrogen Clearance

A major limitation of laser-Doppler (LD) flowmetry, which enables noninvasive and continuous recording of tissue perfusion, is its inability to evaluate the absolute cerebral blood flow (CBF). Using a computer-controlled micromanipulator, the LD scanning technique provides information on the brain microcirculation in many different locations, information which is not available from a single stationary probe. The purpose of the current study was to examine whether LD scanning estimates can be calibrated for the absolute CBF by comparing LD scanning with the hydrogen clearance (HC) method. In Wistar rats (n = 31) including old rats (122–123 weeks old, n = 8), the CBF was altered using the global ischemia model by bilateral carotid artery occlusion coupled with hypobaric hypotension. The CBF was determined simultaneously by the LD scanning technique and HC at each mean arterial blood pressure step, and the correlation of CBF between the two techniques was analyzed. CBF measured by LD scanning was expressed as LD units. Absolute CBF values obtained by methods were correlated (r = 0.87), and the formula to calibrate absolute CBF values from LD units was y = 1.8x – 0.6. On the other hand, in old rats the formula to calibrate the absolute values was different (y = 1.3x + 8.3, r = 0.85). The results suggest that CBF data obtained by LD scanning could be calibrated into absolute blood flow values in particular circumstances, and that LD scanning could compensate in part for the weakness of LD flowmetry.
An Empirical Research on Relationship between Information Technology Capability and Firm Performance the Evidence from the Listed Companies and Informatization Power 500 in China

This paper empirically examines the relationship between information technology (IT) capability and firm performance in Chinese manufacturing industry based on objective evaluation. A matched-sample comparison group methodology, publicly available ratings and performance data from annual financial reports of listed companies are used to assess IT capability and firm performance. Our results indicate that firms with superior IT capability outperform a control sample of firms on a variety of long-term operational, growth and profitability performance measures. However, for the short-term performance, only operational performance outperforms, growth and profitability performance do not outperform.
Two Way Prayer: A Lost Tool for Practicing the 11th Step

ABSTRACT Two Way Prayer formed an essential part of Oxford Group and early Alcoholics Anonymous (AA) spiritual practices. Pioneer AA members considered it more essential for recovery than attendance at meetings; however, it was gradually lost as a component of contemporary 12-Step programs. The article gives an overview of its history and provides a model for a more contemporary form of its practice. Initial evaluation suggests promising outcomes among a sampling of youth and adults engaged in a peer-support group for drug and alcohol recovery. The article includes a discussion of its use with individuals not having a religious conception of spirituality.
Defect localization using physical design and electrical test information

In this work we describe an approach of using physical design and test failure knowledge to localize defects in random logic. We term this approach computer-aided fault to defect mapping (CAFDM). An integrated tool has been developed on top of an existing commercial ATPG tool. CAFDM was able to correctly identify the defect location and layer in all 9 of the chips that had bridging faults injected via FIB. Preliminary failure analysis results on production defects are promising.
In vivo Imaging of Mitochondrial Transport in Single-Axon Regeneration of Zebrafish Mauthner Cells

Mitochondrial transport is essential for neuronal function, but the evidence of connections between mitochondrial transport and axon regeneration in the central nervous system (CNS) of living vertebrates remains limited. Here, we developed a novel model to explore mitochondrial transport in a single Mauthner axon (M axon) of zebrafish with non-invasive in vivo imaging. To confirm the feasibility of using this model, we treated labeled zebrafish with nocodazole and demonstrated that it could disrupt mitochondrial transport. We also used two-photon laser axotomy to precisely axotomize M axons and simultaneously recorded their regeneration and the process of mitochondrial transport in living zebrafish larvae. The findings showed that the injured axons with stronger regenerative capability maintain greater mitochondrial motility. Furthermore, to stimulate axon regeneration, treatment with dibutyryl cyclic adenosine monophosphate (db-cAMP) could also augment mitochondrial motility. Taken together, our results provide new evidence that mitochondrial motility is positively correlated with axon regeneration in the living vertebrate CNS. This promising model will be useful for further studies on the interaction between axon regeneration and mitochondrial dynamics, using various genetic and pharmacological techniques.
Quasi-isometric rigidity for PSL(2,Z[1/p])

We prove that PSL(2,Z[1/p]) gives the first example of groups which are not quasi-isometric to each other but have the same quasi-isometry group. Namely, PSL(2,Z[1/p]) and PSL(2,Z[1/q]) are not quasi-isometric unless p=q, and, independent of p, the quasi-isometry group of PSL(2,Z[1/p]) is PSL(2,Q). In addition, we characterize PSL(2,Z[1/p]) uniquely among all finitely generated groups by its quasi-isometry type.
Randomised controlled trial examining the effect of an outpatient exercise training programme on haemodynamics and cardiac MR parameters of right ventricular function in patients with pulmonary arterial hypertension: the ExPAH study protocol

Introduction Pulmonary hypertension (PH) is a potentially life-threatening condition characterised by elevated pulmonary artery pressure. Early stage PH patients are often asymptomatic. Disease progression is associated with impairment of right ventricular function and progressive dyspnoea. Current guidelines recommend exercise training (grade IIa, level B). However, many questions remain regarding the mechanisms of improvement, intensity of supervision and optimal frequency, duration and intensity of exercise. This study will assess the effect of an outpatient rehabilitation programme on haemodynamics and cardiac right ventricular function in patients with pulmonary arterial hypertension (PAH), a subgroup of PH. Methods and analysis This randomised controlled trial involves both a major urban tertiary and smaller regional hospital in New South Wales, Australia. The intervention will compare an outpatient rehabilitation programme with a control group (home exercise programme). Participants will be stable on oral PAH-specific therapy. The primary outcome measure will be right ventricular ejection fraction measured by cardiac MRI. Secondary outcomes will include haemodynamics measured by right heart catheterisation, endurance, functional capacity, health-related quality of life questionnaires and biomarkers of cardiac function and inflammation. Ethics approval and dissemination Ethical approval has been granted by St Vincent's Hospital, Sydney (HREC/14/SVH/341). Results of this study will be disseminated through presentation at scientific conferences and in scientific journals. Trial registration number ACTRN12615001041549; pre-results.
A Strong Anti-Inflammatory Signature Revealed by Liver Transcription Profiling of Tmprss6−/− Mice

Control of systemic iron homeostasis is interconnected with the inflammatory response through the key iron regulator, the antimicrobial peptide hepcidin. We have previously shown that mice with iron deficiency anemia (IDA)-low hepcidin show a pro-inflammatory response that is blunted in iron deficient-high hepcidin Tmprss6 KO mice. The transcriptional response associated with chronic hepcidin overexpression due to genetic inactivation of Tmprss6 is unknown. By using whole genome transcription profiling of the liver and analysis of spleen immune-related genes we identified several functional pathways differentially expressed in Tmprss6 KO mice, compared to IDA animals and thus irrespective of the iron status. In the effort of defining genes potentially targets of Tmprss6 we analyzed liver gene expression changes according to the genotype and independently of treatment. Tmprss6 inactivation causes down-regulation of liver pathways connected to immune and inflammatory response as well as spleen genes related to macrophage activation and inflammatory cytokines production. The anti-inflammatory status of Tmprss6 KO animals was confirmed by the down-regulation of pathways related to immunity, stress response and intracellular signaling in both liver and spleen after LPS treatment. Opposite to Tmprss6 KO mice, Hfe−/− mice are characterized by iron overload with inappropriately low hepcidin levels. Liver expression profiling of Hfe−/− deficient versus iron loaded mice show the opposite expression of some of the genes modulated by the loss of Tmprss6. Altogether our results confirm the anti-inflammatory status of Tmprss6 KO mice and identify new potential target pathways/genes of Tmprss6.
Treatment by repeating phrases of positive thoughts (TRPPT): A new effective treatment tool against psychological troubles (PSYT) (Depression, anxiety, stress, low self-esteem and dissatisfaction in life) in multiple sclerosis patients and students, a controlled and randomized pilot study.

Introduction: Psychological troubles (PSYT) are common co-morbidities symptoms in multiple sclerosis (MS). Negative verbal thinking style plays a causal role in maintaining intrusions, perhaps serving to trigger subsequent depressive and anxious symptoms and psychological distress. Positive verbal thinking style plays protective role against these symptoms. Objective: The objective of this study was the first to evaluate the short-term effects of the TRPPT method (Treatment by Repeating Phrases of Positive Thoughts). Method: The total of (27) participants, 20 students from the University of Damascus and 7 MS patients from Damascus Hospital and Ibn Alnafees Hospital. Results: Experimental group who has benefited from RPPT have had less depression, less anxiety and less stress and there were significant differences between experimental and control groups. According to value of effect size (Cohen's d), NAT (1.595; 1.822), depression (1.446; 2.615), anxiety (1.492; 2.286), stress (1.395; 2.363) decrease after TRPPT; and PAT (1.643; 2.162) self-esteem (2.204; 1.676) and satisfaction in life (1.432; 1.781) improve among MS patients and students after TRPPT, respectively. The results showed a significant reduction in psychological disturbances throughout the experimental group (p<0.05) and a significant reduction in stress following the RPPT protocol (p<0.01), less anxiety (p<0.001) and also less depression (p<0.05). The short-term effect RPPT (repeating phrases positive thoughts) is significant. A low score of psychological disorders have emerged as one independent variable predictive of a good response to treatment by RPPT method. Conclusion: The positive cognitions improve the treatment of depression, anxiety and stress in clinical sample (MS patients) and non- clinical one (students) and it also enhance their selfesteem and their quality of life. Unlike medicinal treatments, there is no consumption limit or adverse side effects. TRPPT is new psychotherapeutic approach against psychological disorders. Contrary to NAT, increased PAT predicted decreased psychopathy. So, the optimal state of mind based on TRPPT is characterized by the optimal balance between cognitive and affective structure, corresponding to an adaptive and flexible balance in healthy persons in neutral situations. This theoretically optimal state of mind is positively balanced, but at the same time includes sufficient negative cognition to remain realistically cautious.
