Sentiment Dispersion and Asset Pricing Error: Evidence from the Chinese Stock Market

ABSTRACT Previous studies have suggested that the impact of investor sentiment on asset pricing error is determined by the difference between the aggregate sentiment of optimistic and pessimistic investors. This article has found the influence of the in-group sentiment dispersion of optimistic and pessimistic investors on pricing error. We established a two-period model of heterogeneous investors and described the sentiment dispersion of the optimistic and pessimistic groups with the variance of sentiment bias. The results suggested that when the sentiment dispersion of the two groups are identical, the pricing error depends on the aggregate sentiments of the optimistic and pessimistic groups. Conversely, when the two groups have different sentiment dispersion, the pricing error is determined by both the sentiment dispersion ratio and the aggregate sentiment ratio. Finally, data from the Chinese stock market are generated to verify the above conclusions.
Autism spectrum disorder symptoms in juvenile suspects of sex offenses.

OBJECTIVE To investigate autism spectrum disorder (ASD) symptoms in juvenile suspects of sex offenses. METHOD A group of 175 juvenile suspected sex offenders (all males, mean +/- SD age = 14.9 +/- 1.4 years) was compared with a matched healthy control group (N = 500, mean +/- SD age = 14.0 +/- 1.4 years) and a group of children with DSM-IV-diagnosed ASD (N = 114, mean +/- SD age = 14.2 +/- 1.9 years) with respect to autistic symptoms as measured by means of a standardized questionnaire, the Children's Social Behavior Questionnaire. Furthermore, specific subgroups of sexual offenders, i.e., child molesters, solo peer offenders, and group offenders, were compared with regard to levels of ASD symptoms. The study was conducted from May 2003 to December 2006. RESULTS Significantly higher levels of ASD symptoms were found in juvenile sex offenders than in healthy controls, while levels were lower than in the ASD group (F = 148.259, p < .05). Solo peer offenders and child molesters scored higher on several subscales as well as on core autistic symptoms than group offenders (F = 5.127, p < .05). CONCLUSIONS Levels of ASD symptoms are higher in juvenile suspects of sex offenses as compared to the healthy population, which argues for considering specific diagnostic assessment in this population, especially in solo offenders and child molesters.
Successful use of reduced‐intensity conditioning and matched‐unrelated hematopoietic stem cell transplant in a child with Diamond‐Blackfan anemia and cirrhosis

For patients with DBA who are transfusion dependent, HSCT is the only cure. Chronic transfusions can lead to cirrhosis secondary to iron overload, making them poor candidates for myeloablative HSCT. RIC regimens are associated with lower morbidity and mortality compared to myeloablative regimens, but use of RIC in DBA has been limited. Here we present a 14‐yr‐old girl with DBA and multiple comorbidities including liver cirrhosis, who underwent MUD HSCT utilizing a RIC regimen that is novel to this condition. She tolerated the regimen well, and at 21 months, she remains transfusion independent with chimerisms at 99%.
Strongyloides stercoralis: a field-based survey of mothers and their preschool children using ELISA, Baermann and Koga plate methods reveals low endemicity in western Uganda

Abstract To ascertain the current status of strongyloidiasis in mothers and their preschool children, a field-based survey was conducted in western Uganda using a combination of diagnostic methods: ELISA, Baermann concentration and Koga agar plate. The prevalence of other soil-transmitted helminthiasis and intestinal schistosomiasis were also determined. In total, 158 mothers and 143 children were examined from five villages within Kabale, Hoima and Masindi districts. In mothers and children, the general prevalence of strongyloidiasis inferred by ELISA was ~4% and ~2%, respectively. Using the Baermann concentration method, two parasitologically proven cases were encountered in an unrelated mother and child, both of whom were sero-negative for strongyloidiasis. No infections were detected by Koga agar plate method. The general level of awareness of strongyloidiasis was very poor ( < 5%) in comparison to schistosomiasis (51%) and ascariasis (36%). Strongyloidiasis is presently at insufficient levels to justify inclusion within a community treatment programme targeting maternal and child health. Better epidemiological screening is needed, however, especially identifying infections in HIV-positive women of childbearing age. In the rural clinic setting, further use of the Baermann concentration method would appear to be the most immediate and pragmatic option for disease diagnosis.
Factors influencing CO2 Emission in China: A Nonlinear Autoregressive Distributed Lags Investigation

This paper investigates the environmental impact of economic growth, energy consumption, financial development and globalization in China over the period 1970Q1-2015Q4. In particular we consider four dimensions of globalization namely economic, social, political and overall globalization. The Nonlinear Autoregressive Distributed Lags (NARDL) model has been employed to capture the potential asymmetric impact of the determinants of dioxide carbon emissions in China. Interestingly, findings show that: (1) In the short-run: economic growth and financial development have a significant symmetric impact on CO2 emissions. Energy consumption has a nonlinear and asymmetric influence on CO2 emissions. However, economic globalization does not impact CO2 emissions. (2) In the long-run: economic growth, financial development and economic globalization exhibit an asymmetric influence on carbon emissions in model including the economic dimension of globalization. Economic growth has a positive symmetric impact on CO2 emissions in model including social globalization, however, it does not influence CO2 emissions in case of political or overall globalization. In addition, energy consumption is positively linked to CO2 emissions. Moreover, financial development does not influence carbon emission in models including respectively social, political and overall globalization. Social and overall globalization have a significant influence on CO2 emissions. The results of this paper are important for policies that would promote sustainable development and environment protection.
Feasibility and assessment of non-invasive in vivo redox status using electron paramagnetic resonance imaging.

PURPOSE To test the feasibility of electron paramagnetic resonance imaging (EPRI) to provide non-invasive images of tissue redox status using redox-sensitive paramagnetic contrast agents. MATERIAL AND METHODS Nitroxide free radicals were used as paramagnetic agents and a custom-built 300 MHz EPR spectrometer/imager was used for all studies. A phantom was constructed consisting of four tubes containing equal concentrations of a nitroxide. Varying concentrations of hypoxanthine/xanthine oxidase were added to each tube and reduction of the nitroxide was monitored by EPR as a function of time. Tumor-bearing mice were intravenously infused with a nitroxide and the corresponding reduction rate was monitored on a pixel-by-pixel basis using 2D EPR of the tumor-bearing leg and normal leg serving as control. For animal studies, nitroxides were injected intravenously (1.25 mmol/kg) and EPR projections were collected every 3 min after injection using a magnetic field gradient of 2.5 G/cm. The reduction rates of signal intensity on a pixel-by-pixel basis were calculated and plotted as a redox map. Redox maps were also collected from the mice treated with diethylmaleate (DEM), which depletes tissue thiols and alters the global redox status. RESULTS Redox maps obtained from the phantoms were in agreement with the intensity change in each of the tubes where the signals were decreasing as a function of the enzymatic activity, validating the ability of EPRI to accurately access changes in nitroxide reduction. Redox imaging capability of EPR was next evaluated in vivo. EPR images of the nitroxide distribution and reduction rates in tumor-bearing leg of mice exhibited more heterogeneity than in the normal tissue. Reduction rates were found to be significantly decreased in tumors of mice treated with DEM, consistent with the depletion of thiols and the consequent alteration of the redox status. CONCLUSION Using redox-sensitive paramagnetic contrast agents, EPRI can non-invasively discriminate redox status differences between normal tissue and tumors.
Expression of spermadhesin genes in porcine male and female reproductive tracts

Spermadhesins, secretory proteins of the male genital tract, constitute the bulk of seminal plasma proteins in pig. The nucleotide sequences of spermadhesins AWN, AQN‐1, and AQN‐3 from the cDNAs, derived from seminal vesicles, were determined. The coding sequences of spermadhesins revealed an overall sequence similarity of 40% at nucleotide level. Expression of spermadhesins (AWN, AQN‐1, AQN‐3, PSP‐I, and PSP‐II) in porcine male and female reproductive tracts were studied by means of RT‐PCR and immunological approaches. All spermadhesins are transcribed and translated in seminal vesicles and prostate. In caudal epididymis mRNA transcripts of all spermadhesins have been detected by RT‐PCR. PSP‐I showed additional signals in caput epididymis and rete testis. Translation can be detected only for AWN in tissue extracts by SDS–PAGE and Western blotting. Remarkably, AWN is the only spermadhesin that is also expressed in the uterus, the uterotubal junction, and the oviduct of the female genital tract as shown by RT‐PCR, cDNA‐sequencing, and immunological analysis. In sows at estrus and interestrus, in gilts and gilts 12 hr after insemination no obvious differences were noticed in the pattern of AWN‐immunoreactivity in epithelial cells either of the uterotubal junction, isthmus, or ampulla. While strong staining was observed in the superficial uterine glands and in the glands of the uterotubal junction during estrus, in diestrus this declined distinctly. The role of spermadhesins in relation to their expression is discussed. Mol. Reprod. Dev. 61: 32–41, 2002. © 2002 Wiley‐Liss, Inc.
Roles of transport and mixing processes in kelp forest ecology

Summary Fluid-dynamic transport and mixing processes affect birth, death, immigration and emigration rates in kelp forests, and can modulate broader community interactions. In the most highly studied canopy-forming kelp, Macrocystis pyrifera (the giant kelp), models of hydrodynamic and oceanographic phenomena influencing spore movement provide bounds on reproduction, quantify patterns of local and regional propagule supply, identify scales of population connectivity, and establish context for agents of early life mortality. Other analyses yield insight into flow-mediated species interactions within kelp forests. In each case, advances emerge from the use of ecomechanical approaches that propagate physical–biological connections at the scale of the individual to higher levels of ecological organization. In systems where physical factors strongly influence population, community or ecosystem properties, such mechanics-based methods promote crucial progress but are just beginning to realize their full potential.

Serologic Tests for Detecting Antibodies against Mycobacterium Bovis and Mycobacterium Avium Subspecies Paratuberculosis in Eurasian Wild Boar (Sus Scrofa Scrofa)

New tools to detect exposure of free-range Eurasian wild boar (Sus scrofa scrofa) to pathogenic mycobacteria would be valuable for improved disease surveillance and wildlife management. Two hundred sera from wild boar of known Mycobacterium bovis infection status were used to evaluate test suitability for the detection of antibodies against M. bovis and Mycobacterium avium subsp. paratuberculosis (or cross-reacting members of the M. avium complex). Two traditional enzyme-linked immunosorbent assays were evaluated using M. bovis purified protein derivative (bPPD) and paratuberculosis protoplasmatic antigen 3 (PPA3) as antigens, respectively, and a new point-of-care test format for bovine tuberculosis (bTB) that uses the innovative dual-path platform (DPP TB) test. The effect of individual factors (sex, age, lesions) on the diagnostic performance of the serologic tests was also determined. Although the DPP had a sensitivity of 89.6% and a specificity of 90.4%, for bPPD, the sensitivity was 79.2% and the specificity 100%. Both tests had a kappa agreement of 0.80. Sixty-five of 68 (95.6%) wild boar sera with antibodies against the PPA3 antigen corresponded to known M. bovis–infected wild boar. Significant differences were not observed in the bPPD and DPP readings among lesion categories or between age classes. A slight sex-related difference in sensitivity toward males in the DPP was found, but it was not detected in the bPPD enzyme-linked immunosorbent assay. The results support the use of antibody-based diagnostic tests for both large-scale and individual bTB testing of Eurasian wild boar and suggest that wild boar cannot be used as sentinels for infections caused by M. avium complex members.
An Energy efficient scheduling scheme for wireless sensor networks

We consider Energy efficient multiple access control protocol in wireless sensor networks. With the perspective of a synchronous and schedule access protocol, an optimization problem is formulated to schedule operation modes (transmit, receive and sleep) throughout the network. Using dual decomposition, a protocol is designed collaboratively by sensor nodes over time, each node determines its own schedule. This protocol attains statistical convergence with respect to time-varying channel state information in the time of its scope. Numerical results demonstrate the effectiveness of this protocol in terms of consumed energy in comparison with classical protocols as a result of eliminating idle listening in the network.
Efficacy comparison of adjuvants in PcrV vaccine against Pseudomonas aeruginosa pneumonia

Vaccination against the type III secretion system of P. aeruginosa is a potential prophylactic strategy for reducing the incidence and improving the poor prognosis of P. aeruginosa pneumonia. In this study, the efficacies of three different adjuvants, Freund's adjuvant (FA), aluminum hydroxide (alum) and CpG oligodeoxynucleotide (ODN), were examined from the viewpoint of inducing PcrV‐specific immunity against virulent P. aeruginosa. Mice that had been immunized intraperitoneally with recombinant PcrV formulated with one of the above adjuvants were challenged intratracheally with a lethal dose of P. aeruginosa. The PcrV–FA immunized group attained a survival rate of 91%, whereas the survival rates of the PcrV–alum and PcrV–CpG groups were 73% and 64%, respectively. In terms of hypothermia recovery after bacterial instillation, PcrV–alum was the most protective, followed by PcrV–FA and PcrV–CpG. The lung edema index was lower in the PcrV–CpG vaccination group than in the other groups. PcrV–alum immunization was associated with the greatest decrease in myeloperoxidase in infected lungs, and also decreased the number of lung bacteria to a similar number as in the PcrV–FA group. There was less neutrophil recruitment in the lungs of mice vaccinated with PcrV–alum or PcrV–CpG than in those of mice vaccinated with PcrV–FA or PcrV alone. Overall, in terms of mouse survival the PcrV–CpG vaccine, which could be a relatively safe next‐generation vaccine, showed a comparable effect to the PcrV–alum vaccine.
Increased level of active GSK‐3β in Alzheimer’s disease and accumulation in argyrophilic grains and in neurones at different stages of neurofibrillary degeneration

The somatodendritic accumulation of hyperphosphorylated tau proteins is an early event preceding the appearance of neurofibrillary tangles (NFT) in Alzheimer’s disease (AD) and might be necessary for their formation. Glycogen synthase kinase‐3β (GSK‐3β) is a physiological kinase for tau that generates many tau phosphorylation sites identified in NFT and in other tau‐positive inclusions. We have studied the cellular distribution and the expression of the active form of GSK‐3β (GSK‐3 pTyr216) in AD patients, in argyrophilic grain disease and in diffuse Lewy body disease. By Western blotting analysis, a significant increase in the level of GSK‐3 (pTyr216) was observed in the frontal cortex of AD patients. A population of neurones showed a somatodendritic accumulation of GSK‐3 (pTyr216) but not of the inactive form of GSK‐3β (GSK‐3 pSer9). Most of these GSK‐3 (pTyr216)‐positive cells were positive for six different phosphotau epitopes known to be generated by GSK‐3β. By using a quadruple labelling method using GSK‐3 (pTyr216) and phosphotau immunolabelling combined with Gallyas and DAPI staining, we examined neurones containing a somatodendritic GSK‐3 (pTyr216) immunoreactivity at different stages of neurodegeneration. A majority of neurones at the pretangle stage without Gallyas‐positive inclusions were GSK‐3 (pTyr216) positive and this GSK‐3 (pTyr216) immunoreactivity remained in most cells containing Gallyas and phosphotau‐positive inclusions excepted in extracellular NFT. A GSK‐3 (pTyr216) immunoreactivity was present in argyrophilic grains but not in cortical Lewy bodies. These results directly suggest that the activity of GSK‐3β is increased in AD and that somatodendritic accumulation and activation of GSK‐3β is an early event preceding and accompanying the formation of NFT and of other tau‐positive inclusions.
Business Ethics in East Asia

This study investigates business ethics (BE) practices in three East-Asian countries (China, Japan, and South Korea) through a questionnaire. Specifically, ethical attitudes of employees working in major native companies in each mentioned country are studied. We find that a number of similarities as well as differences exist regarding BE practices in the three countries, which can be partially attributed to different political, economic, and socio-cultural backgrounds. This study significantly contributes to the existing literature on BE and has practical implications for any agents interested in ethical aspects on business environment in the investigated countries.
Fabrication, Characterization of Chitosan/Nanosilver Film and Its Potential Antibacterial Application

In this work chitosan/silver nanoparticle films were synthesized by a simple photochemical method of reduction of silver ions in an acidic solution of AgNO3 and chitosan. This is a novel, cheap, easy, quick and in situ approach to prepare chitosan films loaded with silver nanoparticles (AgNPs). Chitosan used here is a natural polymer and acts as a very good chelating and stabilizing agent; thus, this approach of formation of chitosan/silver nanoparticle films is proved to be an excellent 'green approach' for the synthesis of metal nanoparticle composites. The presence of silver nanoparticles was confirmed from the transmission electron microscopy (TEM), X-ray diffraction (XRD) and thermogravimetric analysis (TGA) of the film. The surface plasmon resonance (SPR) obtained at 400 nm also confirmed the presence of nanosilver in the chitosan film. The developed chitosan–nanosilver films demonstrated excellent antibacterial action against model bacteria, Escherichia coli and Bacillus. This approach can be easily used in the large-scale production of such silver-nanoparticles-loaded chitosan films. These films can be used as antimicrobial packaging materials, as wound dressings and can also be grafted onto various implants.
Cooperation and Competition in Public-Sector Negotiations: A Laboratory Experiment

Abstract Negotiating is a core activity in the public and private sector. Because of varying public service motivation (PSM) between public- and private-sector employees, we expect them to behave differently in negotiations. Moreover, one-shot negotiation settings are often studied even as many real-world negotiations are repeated exchanges. We apply a repeated linear public goods game in a laboratory experiment to test the link between PSM and the level of cooperation by using a sample of graduate and undergraduate students. The results show that high-PSM participants, indeed, contributed more over the entire experiment, and therefore, acted more cooperatively in a repeated negotiation. Matching negotiators to opponents with high-PSM, low-PSM did not alter the level of cooperation in negotiation. Based on this, we conclude that cooperation in repeated negotiations is not conditional on the PSM of opponents. We conclude with implications for theory and practice.
Endovascular photodynamic therapy using mono‐L‐aspartyl‐chlorin e6 to inhibit Intimal hyperplasia in balloon‐injured rabbit arteries

Intimal hyperplasia (IH) leading to restenosis is a major complication of arterial revascularization. The purpose of this study was to investigate the effect of photodynamic therapy (PDT) using mono‐L‐aspartyl chlorin e6 (NPe6) as a photosensitizer and intraluminal radial irradiation for inhibition of IH experimentally.
Molecular characterization of the eps gene cluster of Pseudomonas solanacearum and its transcriptional regulation at a single promoter

Production of EPS I, an unusual exopolysaccharide virulence factor of the phytopathogen Pseudomonas solanacearum, requires the 18 kb eps gene cluster. DNA sequence analysis of the first seven genes of eps (epsAPBCDEF), subcellular localization of their products in maxicells, and phoA fusion analysis showed that: (i) epsA, epsB, epsE, and epsF encode exported or membrane‐associated proteins probably involved in polymerization and/or export of EPS I; (ii) epsC and epsD encode soluble enzymes probably involved in synthesis of sugar components of EPS I (N‐acetylgalactosaminuronic acid and possibly N‐acetyitrideoxygalactose, respectively); and (iii) epsP probably encodes a phosphatase involved in EPS I production in an unknown way. Non‐polar insertional mutagenesis showed that most, if not all, of these eps genes are absolutely required for production of EPS I. Using random eps::lacZ fusions and primer extension we located a transcription start site and promoter upstream of epsA. Analysis of a plasmid with this promoter fused to lacZ showed that a 140 bp regulatory region upstream of the eps transcription start site was sufficient for normal regulation of eps transcription by the multicomponent virulence gene regulatory network of P. solanacearum. Deletion of this eps promoter from a plasmid‐borne epsAPBCDE::lacZ fusion reduced its expression 10‐fold, indicating that this promoter alone is responsible for regulated transcription of an eps operon composed of at least epsAPBCDE. Analysis of genomic and plasmid‐borne eps::lacZ fusions suggested that most remaining eps genes are part of this same operon or, and this is less likely, comprise a second co‐ordinately regulated eps operon.
