Quantitative research was employed for this study and the respondents are Software-as-a-Service subscribers for a customer relationship management (CRM) application. Structural Equation Modeling was used to confirm the measurement model. The results are all significant. The study's insights can assist service organizations in addressing the issues of service recovery satisfaction that can lead to trust and continued usage.
Impact of Size and Delay on Neural Activity in the Rat Limbic Corticostriatal System

A number of factors influence an animal’s economic decisions. Two most commonly studied are the magnitude of and delay to reward. To investigate how these factors are represented in the firing rates of single neurons, we devised a behavioral task that independently manipulated the expected delay to and size of reward. Rats perceived the differently delayed and sized rewards as having different values and were more motivated under short delay and big-reward conditions than under long delay and small reward conditions as measured by percent choice, accuracy, and reaction time. Since the creation of this task, we have recorded from several different brain areas including, orbitofrontal cortex, striatum, amygdala, substantia nigra pars reticulata, and midbrain dopamine neurons. Here, we review and compare those data with a substantial focus on those areas that have been shown to be critical for performance on classic time discounting procedures and provide a potential mechanism by which they might interact when animals are deciding between differently delayed rewards. We found that most brain areas in the cortico-limbic circuit encode both the magnitude and delay to reward delivery in one form or another, but only a few encode them together at the single neuron level.
Impasse-Driven Learning in the Context of Video Games in Chinese Players

This study was designed to elucidate the problem-solving skills used by frequent and infrequent Chinese video game players to negotiate impasses encountered while playing video game. All participants were instructed to think aloud while playing a video game for 20 consecutive minutes. Comments were made with thinking aloud. Findings showed that frequent players made significantly greater reference to insight and game strategies than infrequent players. After reaching an impasse, all players also were most likely to comment on their game progress and potential game strategies to use. Over the course of game play, there are some cross cultural differences were founded.
DYNAMIC TUNER DEVELOPTMENT FOR MEDIUM (cid:2746) SUPERCONDUCT-ING ELLIPTICAL CAVITIES *

The Facility for Rare Isotope Beams (FRIB) is developing a 5-cell 644 MHz β (cid:2925)(cid:2926)(cid:2930) (cid:3404) 0.65 elliptical cavity for a future linac energy upgrade to 400 MeV/u for the heaviest uranium ions. Superconducting elliptical cavities operated in continuous wave, such as the ones for FRIB, are prone to microphonics which can excite mechanical modes of the cavities. It has been shown that the detuning due to micro-phonics can be mitigated with the use of piezo actuators (fast tuner) as opposed to the costly option of increasing the input RF power. The FRIB slow/fast dynamic tuner will be based on the Fermilab experience with similar tuners like those developed for the linac coherent light source (LCLS) II and proton improvement plan (PIP) II. This paper will present the results of tuner properties on the bench.
WikiKreator: Improving Wikipedia Stubs Automatically

Stubs on Wikipedia often lack comprehensive information. The huge cost of editing Wikipedia and the presence of only a limited number of active contributors curb the consistent growth of Wikipedia. In this work, we present WikiKreator, a system that is capable of generating content automatically to improve existing stubs on Wikipedia. The system has two components. First, a text classifier built using topic distribution vectors is used to assign content from the web to various sections on a Wikipedia article. Second, we propose a novel abstractive summarization technique based on an optimization framework that generates section-specific summaries for Wikipedia stubs. Experiments show that WikiKreator is capable of generating well-formed informative content. Further, automatically generated content from our system have been appended to Wikipedia stubs and the content has been retained successfully proving the effectiveness of our approach.
A Review and a Conceptual Framework of Prestige-Seeking Consumer Behavior

This paper discusses the existing consumer knowledge dealing with aspects of prestige, and based on this literature, develops a conceptual framework useful for the analysis of prestige-seeking consumer behavior (PSCB). The purpose of this paper is to combine the concepts of existing research on prestige consumers (rather limited) and studies which examined entirely different aspects of consumer behavior, but coincidentally produce valuable information. By examining all the sources of prestige consumption in a broad and integrated way, we shall provide a new perspective that draws from, rather than substitutes for, previous research. The objectives of this literature review can be summarized as follows: • Contribute to the emerging literature on prestige consumption in examining and defining the key perceived values which form the concept of prestige. • Interpret and expand existing consumer behavior models in order to develop a specific prestige-seeking consumer behavior framework. • Generate a framework to help marketers build and monitor the prestige of brands. • Stimulate further research on prestige-seeking consumer behavior.
An Adaptive Role for Negative Expected Pain in Patients With Neuropathic Pain

Objectives:To study the relationship between expected pain and future outcomes along with the moderating effects of expected pain in neuropathic pain patients. Methods:Study participants were recruited for the Canadian Neuropathic Pain Database. To examine the relationship between expected pain and 6-month pain intensity, pain-related disability, and catastrophizing, multiple regressions were performed. These relationships were adjusted for potential confounding (age, sex, baseline pain intensity, and psychological distress). To evaluate the moderating effect of expected pain on the relationship between baseline pain intensity and 6-month outcomes, pain intensity×expected pain interaction terms were created. Results:Complete data for analysis was available for 560 patients (71%). Expected pain was positively correlated with pain intensity and pain-related disability scores at 6 months. The relationship between baseline pain intensity and 6-month catastrophizing scores was moderated by expected pain (however, despite a similar trend, expected pain did not statistically moderate the relationship between baseline pain intensity and 6-month pain intensity or disability). At higher levels of pain, predicted catastrophizing scores were higher for those with low levels of expected pain than those with high levels of expected pain. An opposite relationship was observed for patients with the lower levels of pain. Discussion:In neuropathic pain patients whose pain does not respond to therapy, high levels of expected pain may relate to relatively lower catastrophizing scores by shifting focus away from futile attempts at “curing” pain toward focusing on achievement of more realistic personal goals.
The Invasion of Coastal Areas in South China by Ipomoea cairica May Be Accelerated by the Ecotype Being More Locally Adapted to Salt Stress

Local adaptation and phenotypic plasticity are two alternative mechanisms used by invasive plants for range expansion. We conducted a series of experiments to investigate the role of these mechanisms in the recent expansion of the invasive Ipomoea cairica from non-saline to salt-stressed coastal habitats. A comparison of the plant’s photosynthetic traits and construction costs across habitats was conducted through a field survey. Meanwhile, a full factorial greenhouse experiment was conducted with two ecotypes (non-saline and coastal) of I. cairica and two salinity gradients (water and 4 g L-1 NaCl solution) to evaluate the roles of the two strategies by comparing their main traits. The results revealed that the construction cost and Amax of I. cairica did not change with the habitat type. The ecotype and saline treatments, however, significantly influenced the plant growth. The non-saline ecotype (NE) generally showed higher or equal plasticity of biomass-allocation and functional traits compared to the coastal ecotype (CE). However, the fitness and biomass of the NE significantly decreased with salinity, whereas those aspects of the CE did not change. Our results indicate that the recent expansion of I. cairica into coastal areas may be accelerated by the local adaptation of the CE to salt stress. Additionally, in South China, the CE will most likely evolve adaptations to both saline and non-saline environments, which will further broaden the invasion range of I. cairica in the future.
Second Class Minors : Molecular Identification of the Autosomal H 46 Histocompatibility Locus as a Peptide Presented by Major Histocompatibility Complex Class II Molecules

CD4 T cells regulate immune responses that cause chronic graft rejection and graft versus host disease but their target antigens remain virtually unknown. We developed a new method to identify CD4 T cell–stimulating antigens. LacZ-inducible CD4 T cells were used as a probe to detect their cognate peptide/MHC II ligand generated in dendritic cells fed with Escherichia coli expressing a library of target cell genes. The murine H46 locus on chromosome 7 was thus found to encode the interleukin 4–induced IL4i1 gene. The IL4i1 precursor contains the HAFVEAIPELQGHV peptide which is presented by A b major histocompatibility complex class II molecule via an endogenous pathway in professional antigen presenting cells. Both allelic peptides bind A b and a single alanine to methionine substitution at p2 defines nonself. These results reveal novel features of H loci that regulate CD4 T cell responses as well as provide a general strategy for identifying elusive antigens that elicit CD4 T cell responses to tumors or self-tissues in autoimmunity.
Safety of neonatal cleft lip repair

Abstract The timing of repair of a cleft lip continues to be debated. One of the reasons for delaying operation has been the belief that there is an increased risk of anaesthesia during the neonatal period. As a contribution to this debate we have analysed the anaesthetic and surgical complications of neonatal cleft lip repair undertaken at a single centre. We made a retrospective study of 99 babies consecutively referred for repair of cleft lip over a five-year period (January 1995–December 1999). In contrast to other series, all babies were considered for neonatal surgery and no exclusion criteria were set. All repairs were undertaken within 28 days of birth (median 4); the median gestational age was 40 weeks (range 34–42) and median birth weight of 3300 g (range 1500–4600 g). Perianaesthetic complications included one case of hypoxia presumably as a result of transitional circulation, one reintubation for poor respiratory effort in a premature baby, and five cases of nasal obstruction, three of which required a nasal stent. All recovered without long-term effects. There were significantly more surgical complications with bilateral repairs than with unilateral (p < 0.03). Breast feeding was achieved in 54 babies by the time of discharge. We found no evidence that neonatal repair of cleft lip is unsafe. Paediatric anaesthetic and intensive care support within a specialised centre are necessary, and close postoperative monitoring is required, with attention to the nasal airway.
Science Teaching Self-Efficacy of First Year Elementary Teachers Trained in a Site Based Program.

The purpose of this study was to determine if the teachers trained in the site based preparation program that had obtained significant gains in self-efficacy were still expressing self-efficacy in science teaching after being in their own classrooms for one year. The 31 returned STEBI (science teaching efficacy belief instrument) surveys were analyzed for any significant changes in mean on the complete instrument and on each of the two constructs of PSTE (personal science teaching efficacy) and STOE (science teaching outcome expectancy). The mean for the entire instrument as well as for each of the two constructs remained statistically unchanged within a 95% confidence interval. The implication for teacher educators is that this specific affective dimension can be significantly enhanced and that increases can be maintained over time. The site based program can provide the four factors Bandura identified as sources of information used to determine self-efficacy. The lasting impact of the site based teacher preparation program on science teaching self-efficacy beliefs throughout the first year of teaching provides support for connecting communities of classroom teachers providing authentic experiences in site based locations with confident classroom teachers for the future.

A No-Arbitrage Vector Autoregression of Term Structure Dynamics with Macroeconomic and Latent Variables

This paper describes the joint dynamics of bond yields and macroeconomic variables in a Vector Autoregression, where identifying restrictions are based on the absence of arbitrage. Using a term structure model with inflation and economic growth factors, we investigate how macro variables affect bond prices and the dynamics of the yield curve. The setup accommodates higher order autoregressive lags for the macro factors. The macro variables are augmented by traditional unobserved term structure factors. We find that the forecasting performance of a VAR improves when no-arbitrage restrictions are imposed. Models that incorporate macro factors forecast better than traditional term structure models with only unobservable factors. Variance decompositions show that macro factors explain up to 85% of the variation in bond yields. Macro factors primarily explain movements at the short end and middle of the yield curve while unobservable factors still account for most of the movement at the long end of the yield curve.
Comparison of cardiac output determined by arterial pulse pressure waveform analysis method (FloTrac/Vigileo) versus lithium dilution method in anesthetized dogs.

OBJECTIVE To compare the determination of cardiac output (CO) via arterial pulse pressure waveform analysis (FloTrac/Vigileo) versus lithium dilution method. DESIGN Prospective study. SETTING University teaching hospital. ANIMALS Six adult dogs. INTERVENTIONS Dogs were instrumented for CO determinations using lithium dilution (LiDCO) and FloTrac/Vigileo methods. Direct blood pressure, heart rate, arterial blood gases, and end-tidal isoflurane (ETIso) and CO(2) concentrations were measured throughout the study while CO was manipulated with different depth of anesthesia and rapid administration of isotonic crystalloids at 60 mL/kg/h. MEASUREMENTS AND MAIN RESULTS Baseline CO measurements were obtained at 1.3% ETIso and were lowered by 3% ETIso. Measurements were obtained in duplicate or triplicate with LiDCO and averaged for comparison with corresponding values measured continuously with the FloTrac/Vigileo method. For 30 comparisons between methods, a mean bias of -100 mL/kg/min and 95% limits of agreement between -311 and +112 mL/kg/min (212 mL/kg/min) was determined. The mean (mL/kg/min) of the differences of LiDCO-Vigileo=62.0402+-0.8383 × Vigileo, and the correlation coefficient (r) between the 2 methods 0.70 for all CO determinations. The repeatability coefficients for the individual LiDCO and FloTrac/Vigileo methods were 187 and 400 mL/kg/min, respectively. Mean LiDCO and FloTrac/Vigileo values from all measurements were 145 ± 68 mL/kg/min (range, 64-354) and 244 ± 144 mL/kg/min (range, 89-624), respectively. The overall mean relative error was 48 ± 14%. CONCLUSION The FloTrac/Vigileo overestimated CO values compared with LiDCO and the relative error was high, which makes this method unreliable for use in dogs.
Factors associated with proviral DNA HIV-1 tropism in antiretroviral therapy-treated patients with fully suppressed plasma HIV viral load: implications for the clinical use of CCR5 antagonists.

OBJECTIVES Most treated HIV-1 patients have undetectable viral loads and the strategies for managing long-term side effects may involve a new class of antiretroviral-like CCR5 antagonists. Tropism determination based on proviral DNA sequence is necessary for patients with a fully suppressed plasma viral load, as assays analysing DNA phenotypes have yet to be developed. We aimed to analyse HIV-1 tropism using proviral DNA sequencing and the associated factors, in a group of patients on antiretroviral (ARV) treatment with an undetectable viral load in plasma. METHODS Blood samples of 140 HIV-1-infected ARV-treated patients with a plasma viral load of <40 copies/mL were studied. All patients had never been treated with CCR5 antagonists. Co-receptor usage was determined using proviral DNA from the V3 env region sequence by Geno2Pheno (false positive rate 10%) and PSSM algorithms. RESULTS Among 140 patients treated using ARV therapy with a fully suppressed plasma viral load, at least 70% of patients had proviral R5-tropic virus. Among all the studied factors (time since HIV infection diagnosis, treatment duration, time since viral load undetectability, HIV subtype, current treatment, age, number of treatment types, sex, genotypic susceptibility score, and nadir and current CD4 cell counts), nadir CD4 T cell count alone was associated with tropism during a multivariate analysis. R5X4/X4 tropism was present in all nadir CD4 categories. CONCLUSIONS Proviral DNA tropism determination should be required, even for patients with a CD4 nadir cell count >350 cells/mm(3), before CCR5 antagonists are used in patients with a fully suppressed plasma viral load.

Widespread occurrence of chromosomal aneuploidy following the routine production of Candida albicans mutants

It has come to our attention that approximately 35% of >100 published microarray datasets, where transcript levels were compared between two different strains, exhibit some form of chromosome-specific bias. While some of these arose from the use of strains whose aneuploidies were not known at the time, in a worrisome number of cases the recombinant strains have acquired additional aneuploidies that were not initially present in the parental strain. The aneuploidies often affected a different chromosome than the one harboring the insertion site. The affected strains originated from either CAI-4, RM1000, BWP17 or SN95 and were produced through a variety of strategies. These observations suggest that aneuploidies frequently occur during the production of recombinant strains and have an effect on global transcript profiles outside of the afflicted chromosome(s), thus raising the possibility of unintended phenotypic consequences. Thus, we propose that all Candida albicans mutants and strains should be tested for aneuploidy before being used in further studies. To this end, we describe a new rapid testing method, based on a multiplex quantitative PCR assay, that produces eight bands of distinct sizes from either the left or right arms of each C. albicans chromosome.
p97 Disease Mutations Modulate Nucleotide-Induced Conformation to Alter Protein–Protein Interactions

The AAA+ ATPase p97/VCP adopts at least three conformations that depend on the binding of ADP and ATP and alter the orientation of the N-terminal protein–protein interaction (PPI) domain into “up” and “down” conformations. Point mutations that cause multisystem proteinopathy 1 (MSP1) are found at the interface of the N domain and D1-ATPase domain and potentially alter the conformational preferences of p97. Additionally, binding of “adaptor” proteins to the N-domain regulates p97’s catalytic activity. We propose that p97/adaptor PPIs are coupled to p97 conformational states. We evaluated the binding of nucleotides and the adaptor proteins p37 and p47 to wild-type p97 and MSP1 mutants. Notably, p47 and p37 bind 8-fold more weakly to the ADP-bound conformation of wild-type p97 compared to the ATP-bound conformation. However, MSP1 mutants lose this nucleotide-induced conformational coupling because they destabilize the ADP-bound, “down” conformation of the N-domain. Loss in conformation coupling to PPIs could contribute to the mechanism of MSP1.
Distributionally Robust Markov Decision Processes

We consider Markov decision processes where the values of the parameters are uncertain. This uncertainty is described by a sequence of nested sets (that is, each set contains the previous one), each of which corresponds to a probabilistic guarantee for a different confidence level. Consequently, a set of admissible probability distributions of the unknown parameters is specified. This formulation models the case where the decision maker is aware of and wants to exploit some (yet imprecise) a priori information of the distribution of parameters, and it arises naturally in practice where methods for estimating the confidence region of parameters abound. We propose a decision criterion based on distributional robustness: the optimal strategy maximizes the expected total reward under the most adversarial admissible probability distributions. We show that finding the optimal distributionally robust strategy can be reduced to the standard robust MDP where parameters are known to belong to a single uncertainty set; hence, it can be computed in polynomial time under mild technical conditions.
