The Financial Markets and Customer Satisfaction: Reexamining Possible Financial Market Mispricing of Customer Satisfaction

We investigate the association between information contained in the American Customer Satisfaction Index (ACSI) metric and future stock market performance. Some past research has provided results suggesting that the financial markets misprice customer satisfaction; i.e., firms advantaged in customer satisfaction are posited to earn positive future-period abnormal stock returns. We reexamine this relationship and find that statistically significant evidence of financial market mispricing of customer satisfaction is limited to firms in the computer and Internet sector. The results suggest that the mispricing anomaly reported in past research appears not to stem from a systemic failure of the financial markets to impound the financial implications of customer satisfaction into current stock price, but rather from abnormal returns achieved by a small group of satisfaction leaders in the computer and Internet sector over the period of study. Analyses based on unconditional risk covariates and analyses using conditional risk covariates estimated from short-window, high-frequency data support this finding.
A Modified Self-Training Semi-supervised SVM Algorithm

In this paper, we present a modified self-training semi-supervised SVM algorithm. In order to demonstrate its validity and effectiveness, we carry out some experiments which prove that our method is better than the former algorithm. Using our modified self-training semi-supervised SVM algorithm, we can save much time for labeling the unlabelled data.
Regional properties of calcium entry in barnacle neurons determined with Arsenazo III and a photodiode array

Calcium changes were simultaneously measured at many positions on individual neurons from the supraesophageal ganglion of the barnacle by detecting absorbance changes of the indicator dye Arsenazo III with a 10 X 10 photodiode array. These changes were correlated with positions on the stimulated cell determined from Lucifer yellow injections. Absorbance signals were found at all locations on the cells, demonstrating that calcium channels were distributed on the somata, axons, and neuropil processes. By comparing the amplitude of the signal with the membrane area in each region, we could measure the calcium entry per impulse per unit of surface in each part of the cell. Assuming that the properties of the calcium channels are the same in all regions, we determined that calcium channels were distributed uniformly along the commissural axon of one cell and were found at higher density in the neuropil. Because significant calcium changes are only detected when cells are depolarized above about -20 mV, the presence of absorbance signals indicates membrane depolarization above this level. We used this fact to show that calcium spikes propagate along the axon and into the neuropil of one cell, along the axon of another, and not at all in a third. Differences in time course of calcium transients were observed in different regions of cells. The recovery time course was faster at the edge of the cell body than in the center and faster in the neuropil than in the axon or soma. During trains of action potentials or during wide action potentials in tetraethylammonium (TEA) saline, the calcium signal reached a plateau in the neuropil while continuing to rise in the axon and soma.

We look for differential equations of the form M ∞ ∑ i=0 ai(x)y (x) + N ∞ ∑ i=0 bi(x)y (x) + MN ∞ ∑ i=0 ci(x)y (x) + (1 − x)y(x) + [β − α − (α + β + 2)x] y′(x) + n(n + α + β + 1)y(x) = 0 satisfied by the generalized Jacobi polynomials { P n (x) } ∞ n=0 which are orthogonal on the interval [−1, 1] with respect to the weight function Γ(α + β + 2) 2α+β+1Γ(α + 1)Γ(β + 1) (1 − x)(1 + x) + Mδ(x + 1) + Nδ(x − 1), where α > −1, β > −1, M ≥ 0 and N ≥ 0. We give explicit representations for the coefficients {ai(x)} ∞ i=0, {bi(x)} ∞ i=0 and {ci(x)} ∞ i=0 and we show that this differential equation is uniquely determined. For M + N > 0 the order of this differential equation is infinite, except for α ∈ {0, 1, 2, . } or β ∈ {0, 1, 2, . }. Moreover, the order equals
Clustering Technique with Potter stemmer and Hypergraph Algorithms for Multi-featured Query Processing

In navigational system, it is important to provide a user with flexible and fast query processing without a search failure as well as to find optimal paths guiding the user to a destination. If a user has to repeat submitting a query several times, the user cannot be satisfied with the system. Using this new technique we can extract the correct information within less time effectively. Applications like multimedia databases or enterprise-wide information management systems have to meet the challenge of efficiently retrieving best matching objects from vast collections of data. Here a technique, “Clustering” supported by potter stemmer and hypergraph algorithm for processing multi-feature queries on diverse data sources is presented. Frequent item sets are generated from the groups of items, followed by clusters formed with a hyper graph partitioning scheme. Furthermore its performance is validated by comparing it with typical search techniques.
Stock Index Prediction Based on the PSOPI-BP Neural Network ⋆

In order to improve the prediction ability of the Neuron Network in stock index prediction, we proposed an improve particle swarm neural network algorithm. The Particle Swarm Optimization algorithm based on Parasitic Immune (PSOPI) was used to optimize combination weights of BP neural network model parameters. The BP algorithm was also to obtain the parameters of network further accurate. Finally, experimental results demonstrate the efficacy of our improved algorithm.
Spheroidal aggregate culture of rat liver cells: histotypic reorganization, biomatrix deposition, and maintenance of functional activities

Liver cells isolated from newborn rats and seeded on a non-adherent plastic substratum were found to spontaneously re-aggregate and to form, within a few days, spheroidal aggregates that eventually reached a plateaued diameter of 150-175 micron. Analyses on frozen sections from these spheroids by immunofluorescence microscopy using antibodies to various cytoskeletal elements and extracellular matrix components revealed a sorting out and a histotypic reorganization of three major cell types. A first type consisted of cells that segregated out on the aggregate surface forming a monolayer cell lining; a second type was identified as hepatocytes that regrouped in small islands often defining a central lumen; and a third group of cells reorganized into bile duct-like structures. This intercellular organization in the aggregates was paralleled by the accumulation of extracellular matrix components (laminin, fibronectin, and collagen) and their deposition following a specific pattern around each cell population structure. Determinations of albumin secretion and tyrosine aminotransferase induction by dexamethasone and glucagon at various times after the initiation of the cultures revealed a maintenance of the hepatocyte- differentiated functions for at least up to 2 mo at the levels measured at 3-5 d. It is concluded that cells dispersed as single cells from newborn rat liver conserve in part the necessary information to reconstruct a proper three-dimensional cyto-architecture and that the microenvironment so generated most likely represents a basic requirement for the optimal functioning of these differentiated cells.
Evaluation System of Suitable Computer Input Device for Patients

In rehabilitation medicine, it is necessary for medical staff members to recommend the suitable computer input device for each patient with spinal cord injury. This paper describes the recommendation and the adjustment of a computer input device for each patient. We propose the device parameter to characterize the computer input device. We measure the moving distance of a mouse cursor in browsing of the Internet to estimate the necessity moving distance in operating the computer. Moreover, we measure the patient's moving distance of his hand. Using these measurement results and the proposed equation, medical staffs can adjust the suitable computer input device for each patient.

Lipopolysaccharide (LPS)-Binding Protein Mediates LPS Detoxification by Chylomicrons 1

Chylomicrons have been shown to protect against endotoxin-induced lethality. LPS-binding protein (LBP) is involved in the inactivation of bacterial toxin by lipoproteins. The current study examined the interaction among LBP, chylomicrons, and bacterial toxin. LBP was demonstrated to associate with chylomicrons and enhance the amount of LPS binding to chylomicrons in a dose-dependent fashion. In addition, LBP accelerated LPS binding to chylomicrons. This LBP-induced interaction of LPS with chylomicrons prevented endotoxin toxicity, as demonstrated by reduced cytokine secretion by PBMC. When postprandial circulating concentrations of chylomicrons were compared with circulating levels of low density lipoprotein, very low density lipoprotein, and high density lipoprotein, chylomicrons exceeded the other lipoproteins in LPS-inactivating capacity. Furthermore, highly purified lipoteichoic acid, an immunostimulatory component of Gram-positive bacteria, was detoxified by incubation with LBP and chylomicrons. In conclusion, our results indicate that LBP associates with chylomicrons and enables chylomicrons to rapidly bind bacterial toxin, thereby preventing cell activation. Besides a role in the detoxification of bacterial toxin present in the circulation, we believe that LBP-chylomicron complexes may be part of a local defense mechanism of the intestine against translocated bacterial toxin.
Activity recognition and nutrition monitoring in every day situations with a textile capacitive neckband

We build on previous work [5] that demonstrated, in simple isolated experiments, how head and neck related events (e.g. swallowing, head motion) can be detected using an unobtrusive, textile capacitive sensor integrated in a collar like neckband. We have now developed a 2nd generation that allows long term recording in real life environments in conjunction with a low power Bluetooth enabled smart phone. It allows the system to move from the detection of individual swallows which is too unreliable for practical applications to an analysis of the statistical distribution of swallow frequency. Such an analysis allows the detection of "nutrition events" such as having lunch or breakfast. It also allows us to see the general level of activity and distinguish between just being absolutely quiet (no motion) and sleeping. The neckband can be useful in a variety of applications such as cognitive disease monitoring and elderly care.
Human Capital and the Lifetime Costs of Impatience

In this paper, we examine the role of impatience in human capital formation—arguably the most important investment decision individuals make during their lifetimes. We focus on a set of investment behaviors that cannot be explained solely by variation in exponential discounting. Using data from the NL SY and a straightforward measure of impatience, we find that impatient people more frequently invest in dynamically inconsistent ways, such as dropping out of college with one year or less remaining. The cumulative investment differences result in the impatient earning 13 percent less and expressing more regret as this cohort reaches middle age. (JEL D91, I26, J24, J31)
New concepts in design of lightweight MDS diffusion layers

Diffusion layers are an important part of most symmetric ciphers and MDS matrices can be used to construct perfect diffusion layers. However, there are few techniques for constructing these matrices with low implementation cost in software/hardware. In this article, we try to give some construction methods of MDS matrices with at least the following properties: Easy implementation, dynamic use and constructing a large family of MDS matrices from one (0, 1)-matrix which is a block-wise MDS matrix. For this purpose, we define an equivalence relation between rings and based on this definition, we classify and determine MDS matrices over equivalent rings. At first, we construct a new family of MDS matrices only with XORs and right or left shifts. Then, we construct another family of MDS matrices with XORs and cyclic shifts operations. Finally, we construct a family of lightweight MDS matrices with the same implementation cost as their inverses for the use in block ciphers.
Aging, motor skill, and the energy cost of walking: implications for the prevention and treatment of mobility decline in older persons.

BACKGROUND Age-associated neural changes profoundly affect the biomechanics and energetics of walking, increase energy cost, and require novel approaches to exercise that focus on motor learning theory. METHODS We present a conceptual framework for motor skill in walking, its effect on the energy cost of walking, and the influence of the aging brain. RESULTS Motor learning theory and practice can be incorporated into interventions to promote skilled, energy efficient walking in older people. CONCLUSIONS An extensive literature on motor skill and motor learning, derived from neuroscience, sports medicine, and neurorehabilitation, can be applied to problems of walking in late life.
Enterprise Architecture Intelligence: Combining Enterprise Architecture and Operational Data

Combining enterprise architecture and operational data is complex (especially when considering the actual 'matching' of data with enterprise architecture objects), and little has been written on how to do this. Therefore, in this paper we aim to fill this gap and propose a method to combine operational data with enterprise architecture to better support decision-making. Using such a method may result either in an enriched enterprise architecture model (which is very suitable as a basis for model-based architecture analyses), or in a warehouse data model where operational data is enriched with enterprise architecture metadata (which leads to more traceability by easing the retrieval and interpretation of raw data, and of business analytics results). The method is illustrated by means of a case study. Also, a model to store enterprise architecture, operational data and time is presented on which new forms of analysis may be performed.
A LIMIT THEOREM FOR CONDITIONALLY INDEPENDENT BEAM SPLITTINGS

Consider a Boson Fock space Γ(L(G,μ)). Then the coherent state φ to a wave function f describes a system of particles in the same one-particle state f/ ‖f‖ in the space G. For testing whether two coherent states φ and φ ′ with ‖f‖ = ‖f ′‖ (i.e., the mean number of particles is equal) belong to the same one-particle state or f ⊥ f ′, one could use the following procedure. One applies a conventional beam splitter which transforms the state φ ⊗ φ ′ into φ(f−f ′)/ √ 2 ⊗ φ ′)/ √ . If f = f ′ the state φ(f−f ′)/ √ 2 is the vacuum φ. Thus measurement using the projection onto the vacuum function in Fock space yields a distribution concentrated on δ1. If f ⊥ f ′, the same measurement has under the state φ(f−f ′)/ √ 2 the distribution e−‖f‖ 2 δ1 + (1 − e−‖f‖ 2 )δ0. For high numbers of particles, i.e. ‖f‖ = ‖f ′‖ 1, we can therefore distinguish between the two situations with high confidence. The basic idea of this procedure was applied to quantum teleportation [11,12] as well as in the modeling of brain recognition processes, see [10]. But, especially in the latter case, the condition ‖f‖ = ‖f‖ is not realistic because the density of the state representing the input-information differs from the individual density of excited neurons in the brain. Therefore there is need for a preprocessing step which makes the mean number of particle of both states equal to each other. Standard quasifree transition operators
Pegylated-Interferon Alpha Therapy for Treatment-Experienced Chronic Hepatitis B Patients

Background Studies are limited on pegylated interferon (Peg-IFN) therapy for chronic hepatitis B (CHB) patients who failed or relapsed on previous antiviral therapy. Objectives We aimed to investigate the effect of Peg-IFN therapy in treatment-experienced CHB patients. Study Design A total of 57 treatment-experienced CHB patients at two medical centers were enrolled. All of the patients were treated with Peg-IFN α-2a at 180 μg weekly for 24 or 48 weeks. The hepatitis B serological markers and viral loads were tested every 3 months until 1 year after stopping Peg-IFN therapy. The endpoints were HBV DNA <2000IU/mL, hepatitis B e antigen (HBeAg) seroconversion, and a hepatitis B surface antigen (HBsAg) loss at 12 months post-treatment. Results In HBeAg-positive patients, 25.0%, 29.2%, and 12.5% of the patients achieved HBeAg seroconversion, HBV DNA <2000 IU/mL and a combined response, respectively, at 12 months post-treatment. Prior IFN therapy, a high baseline ALT level, a low creatinine level, undetectable HBV DNA at 12 weeks and a decline in HBV DNA >2 log10 IU/mL at 12 weeks of therapy were factors associated with treatment response. In HBeAg-negative patients, 9.1%, 15.2%, and 6.1% of the patients achieved undetectable HBV DNA, HBV DNA <2000 IU/mL, and an HBsAg loss, respectively, at 12 months post-treatment. No factor was significantly associated with the treatment response in the HBeAg-negative patients. The median HBsAg level declined from 3.4 to 2.6 log10 IU/mL in all the patients, and the 5-year cumulative rate of the HBsAg loss was 9.8% in the HBeAg-negative patients. Overall, none of the patients prematurely discontinued the Peg-IFN therapy. Conclusions Peg-IFN re-treatment is effective for a proportion of HBeAg-positive treatment-experienced patients; it has limited efficacy for HBeAg-negative treatment-experienced patients. Peg-IFN might facilitate HBsAg loss in HBeAg-negative treatment-experienced patients.
Regular Expressions, au point

We introduce a new technique for constructing a finite state deterministic automaton from a regular expression, based on the idea of marking a suitable set of positions inside the expression, intuitively representing the possible points reached after the processing of an initial prefix of the input string. Pointed regular expressions join the elegance and the symbolic appealingness of Brzozowski's derivatives, with the effectiveness of McNaughton and Yamada's labelling technique, essentially combining the best of the two approaches.
Free p-cresylsulphate is a predictor of mortality in patients at different stages of chronic kidney disease.

BACKGROUND Uraemic toxins are considered to be emerging mortality risk factors in chronic kidney disease (CKD) patients. p-Cresol (a prototype protein-bound uraemic retention solute) has been shown to exert toxic effects in vitro. Recently, it has been demonstrated that p-cresol is present in plasma as its sulphate conjugate, p-cresylsulphate. The present study evaluated the distribution of free and total p-cresylsulphate and sought to determine whether these parameters were associated with vascular calcification, arterial stiffness and mortality risk in a cohort of CKD patients. METHODS One hundred and thirty-nine patients (mean +/- SD age: 67 +/- 12; males: 60%) at different stages of CKD (8% at Stage 2, 26.5% at Stage 3, 26.5% at Stage 4, 7% at Stage 5 and 32% at Stage 5D) were enrolled in this study. RESULTS Baseline total and free p-cresylsulphate presented an inverse relationship with renal function and were significantly associated with vascular calcification. During the study period (mean follow-up period: 779 +/- 185 days), 38 patients died [including 22 from cardiovascular (CV) causes]. In crude survival analyses, free (but not total) p-cresylsulphate was shown to be a predictor of overall and CV death. Higher free p-cresylsulphate levels (>0.051 mg/100 mL; median) were associated with mortality independently of well-known predictors of survival such as age, vascular calcification, anaemia and inflammation. CONCLUSIONS Serum levels of free and total p-cresylsulphate (the main in vivo circulating metabolites of p-cresol) were elevated in later CKD stages. However, only free p-cresylsulphate seems to be a predictor of survival in CKD.
Effects of glucose, glucose plus branched-chain amino acids, or placebo on bike performance over 100 km.

This study was undertaken to determine the effects of ingesting either glucose (trial G) or glucose plus branched-chain amino acids (BCAA: trial B), compared with placebo (trial P), during prolonged exercise. Nine well-trained cyclists with a maximal oxygen uptake of 63.1 +/- 1.5 ml O2. min-1.kg-1 performed three laboratory trials consisting of 100 km of cycling separated by 7 days between each trial. During these trials, the subjects were encouraged to complete the 100 km as fast as possible on their own bicycles connected to a magnetic brake. No differences in performance times were observed between the three trials (160.1 +/- 4.1, 157.2 +/- 4.5, and 159.8 +/- 3.7 min, respectively). In trial B, plasma BCAA levels increased from 339 +/- 28 microM at rest to 1,026 +/- 62 microM after exercise (P < 0.01). Plasma ammonia concentrations increased during the entire exercise period for all three trials and were significantly higher in trial B compared with trials G and P (P < 0.05). The respiratory exchange ratio was similar in the three trials during the first 90 min of exercise; thereafter, it tended to drop more in trial P than in trials G and B. These data suggest that neither glucose nor glucose plus BCAA ingestion during 100 km of cycling enhance performance in well-trained cyclists.
The Self-Regulatory Model of Illness and Adjustment Outcomes in Hepatitis C

This study investigates the ability of illness perceptions and coping strategies, primary features of the self-regulatory model of illness (SRM), which has been utilized in several related chronic disease studies to predict adjustment outcomes among individuals diagnosed with hepatitis C (HCV; Hagger & Orbell, 2003; Leventhal, Diefenbach, & Leventhal, 1992). The study utilized the 8-component Brief Illness Perceptions Questionnaire (BIPQ) and the brief COPE as a measure of coping strategies (Broadbent, Petrie, Main, & Weinman, 2006; Carver, Scheier, & Weintraub, 1989). Individuals diagnosed with HCV (n = 126) completed online questionnaires assessing illness perceptions, coping strategies, and 3 adjustment outcomes (depression, physical health, and life satisfaction). Hierarchical multiple regressions indicated that illness perceptions and coping strategies predicted adjustment across the depression, physical health, and life satisfaction criterion variables. Illness identity accounted for significant variance across depression and physical health outcomes. Personal control made significant contributions to predicting depression, physical health, and life satisfaction outcomes. Illness coherence and emotional responses to HCV predicted depression outcomes, whereas illness timeline accounted for variance in life satisfaction. Maladaptive coping made significant contributions to predicting depression and life satisfaction outcomes. Adaptive coping predicted significant variance in life satisfaction. Results provide support for the inclusion of the SRM within therapeutic models for individuals presenting with HCV.
