Performance analysis of investing in Chinese oil paintings based on a hedonic regression model of price index
Authors: Wang Fang , Zheng Xu 
Published: July 2017

Purpose
The purpose of this paper is to construct a price index for Chinese oil paintings and analyze the financial performance of investing in Chinese oil paintings and its potential for portfolio diversification in Chinese financial markets.

Design/methodology/approach
A hedonic regression model is applied to construct a semiannual price index for Chinese oil paintings from 2000 to 2014. The CAPM model, downside β and standard portfolio optimization are used for analyzing portfolio diversification.

Findings
The hedonic regression shows that the majority of hedonic variables, such as dimension, artist’s reputation, living status, medium and auction houses, are statistically significant in estimation. Not only the return from oil painting investments is higher than other equities, but also the β coefficient of the CAPM model and downside β indicate that Chinese oil painting may be a good hedging instrument against stock market risk. Furthermore, the portfolio optimizations under standard assumptions suggest that oil paintings as an alternative investment provide diversification benefit.

Originality/value
This paper provides a new and comprehensive analysis of characteristics and risks of investing in the Chinese oil paintings.

The innovating firm as corporate entrepreneurship
Authors: Urban Boris , Wood Eric 
Published: July 2017

Purpose
Innovation is a multi-dimensional phenomenon and at the firm level incorporates the behaviors and interactions of individuals and various organizational factors. Not only are entrepreneurship and innovation complementary, but a combination of the two is vital to organizational success. The purpose of this paper is to respond directly to research calls to provide an integrated model of corporate entrepreneurship (CE) which encompasses both organizational- and individual-level factors.

Design/methodology/approach
A model was formulated in accordance with the study hypotheses and statistically tested. A sample of 784 responses from the South African financial sector was surveyed. Structural equation modeling (SEM) was used to test for model fit.

Findings
The results support the hypotheses that it is through the interaction of the firm (in establishing corporate building blocks), and the individual (through entrepreneurial alertness and metacognitions) that CE activity is realized. SEM results showed that entrepreneurial alertness had the greatest direct path impact on CE.

Practical implications
Managers need to understand and leverage corporate building blocks in a manner that influences employee’s respective levels of entrepreneurial alertness and metacognitions in order to foster CE.

Originality/value
The study is one of the first to model and empirically test causal links between corporate building blocks, entrepreneurial alertness, metacognitions, and CE at the firm level. Moreover, the study takes place in an under-researched African context, allowing for fresh insights to evolve.
Role of personality style on bargaining outcomes
Authors: McCannon Bryan C. , Stevens John 
Published: July 2017

PurposeThe purpose of this paper is to identify whether personality traits can help explain the outcomes that arise in bargaining outcomes.Design/methodology/approachExperiments with subjects playing the alternating-offers bargaining game are considered. Both full information and asymmetric information treatments are considered. Subjects also complete standardized Myers-Briggs Type Indicator assessments.FindingsPersonality type measurements are shown to help explain the opening offers, rejections, and resulting wealth in the negotiations. It is shown that interactions between the personality dimensions are important and that the interaction between personality and information play a key role in bargaining outcomes.Research limitations/implicationsThe research utilizes laboratory experiments to generate data. This expands our understanding of individual-level behavior, but suffers from the limitation of not replicating realistic bargaining situations.Practical implicationsThe work should serve as a guide to organizations to identify traits of effective negotiators.Social implicationsBargaining is a central economic activity. Being able to identify the root of differences in outcomes from negotiations should be able to inform institutional design issues.Originality/valueLittle work has been done connecting the rich literature in social psychology and management on personality to economic outcomes. The research on bargaining neglects to incorporate individual-level traits into the process. This research begins to bridge this gap and informs both bargaining theory as well as emphasizes on the importance of personality in application.
Hyperuricemia is an independent risk factor for psoriatic arthritis in psoriatic patients
Authors: Tsuruta Noriko , Imafuku Shinichi , Narisawa Yutaka 
Published: July 2017

AbstractPsoriatic arthritis (PsA) is a spondyloarthritic condition mainly seen in patients with psoriasis. Psoriatic patients with plaques on the scalp, gluteal fold or nail lesions are known to develop PsA more frequently, but other markers for PsA have not yet been identified. To determine which psoriatic patients are at greatest risk of developing PsA, psoriasis vulgaris (PsV) patients who visited the Department of Dermatology, Fukuoka University Hospital in 2015 were enrolled. Patients with and without PsA were statistically compared with respect to age, sex, age at onset, body mass index (BMI), smoking and drinking habits, familial history of psoriasis and comorbidities. Of 331 patients (237 men, 94 women), 55 had PsA (17%; 39 men, 16 women). PsA patients had significantly higher frequencies of nail lesions (PsA vs PsV‐only, 62% vs 29%; P < 0.0001) and hyperuricemia (PsA vs PsV‐only, 22% vs 9%; P = 0.01). These were confirmed as independent risk factors for PsA by logistic regression analysis, with odds ratios of 5.05 for nail lesions (P < 0.0001) and 4.18 for hyperuricemia (P < 0.01). There was no difference in age at onset, sex, BMI and incidence of diabetes mellitus, hypertension or dyslipidemia. Hyperuricemia is also known to be more frequent in psoriatic subjects than the normal population. Uric acid crystals are a strong stimulator of innate immunity. Considering that none of our cohort had gouty arthritis, hyperuricemia may increase uric acid crystallization in and around joints, thereby inducing PsA in psoriatic subjects. Hyperuricemia appears to be an independent risk factor for PsA.
New cooperative medical scheme and medical expenditure in rural China
Authors: Li Li 
Published: July 2017

AbstractThe New Cooperative Medical Scheme (NCMS) was launched in rural China in 2003, aiming to safeguard rural households against catastrophic medical expenditure. The implementation of the programme has been surrounded by the concern for the potential uncontrollable growth in medical expenditure due to moral hazard. Direct evidence on the relationship between the NCMS and total medical expenditure is still scant. Using a panel data set, the Rural Fixed‐point Survey (RFPS) 2003–2006 and a supplementary NCMS survey conducted in 2007, we find that joining the NCMS does not affect household medical expenditure.

Published: July 2017

AbstractWe report the case of a middle‐aged man, without medical history, who suddenly died at his workplace. The autopsy highlighted a pathological heart macroscopically, with multiple small white areas on the left myocardium. Coronary dissection revealed a pseudotumoural fibromyxoid aspect within the anterior interventricular artery (AIVA) and the left main coronary trunk, including reduction in their diameter with tight stenosis. Microscopic examination of these arteries showed fibroinflammatory wall destruction. In the left myocardium, there were multiple focal ischemic areas at different stages of recovery. Our case is an illustration of primary ischemic heart disease due to coronary arteritis, with a pseudotumoural presentation, which was revealed by sudden death. We discuss the cause of death and the etiological diagnosis preceding coronary arteritis.

Published: July 2017

AbstractThe purpose of this study was to explore the factors related to earthquake preparedness in Japanese hemodialysis patients. We focused on three aspects of the related factors: health condition factors, social factors, and the experience of disasters. A mail survey of all the members of the Japan Association of Kidney Disease Patients in three Japanese prefectures (N = 4085) was conducted in March, 2013. We obtained 1841 valid responses for analysis. The health factors covered were: activities of daily living (ADL), mental distress, primary renal diseases, and the duration of dialysis. The social factors were: socioeconomic status, family structure, informational social support, and the provision of information regarding earthquake preparedness from dialysis facilities. The results show that the average percentage of participants that had met each criterion of earthquake preparedness in 2013 was 53%. Hemodialysis patients without disabled ADL, without mental distress, and requiring longer periods of dialysis, were likely to meet more of the earthquake preparedness criteria. Hemodialysis patients who had received informational social support from family or friends, had lived with spouse and children in comparison to living alone, and had obtained information regarding earthquake preparedness from dialysis facilities, were also likely to meet more of the earthquake preparedness criteria.
The Effects of Governance on Classification Shifting and Compensation Shielding
Authors: Joo Jeong Hwan , Chamberlain Sandra L. 
Published: July 2017

AbstractPrior research (e.g., Dechow, Huson, and Sloan ) documents that, on average, compensation practices appear to shield CEO pay from income‐decreasing special items. In some circumstances, compensation shielding can be efficient. For example, it may encourage CEOs with earnings‐sensitive pay to take an action that reduces current earnings but nevertheless enhances value. Compensation shielding can be inefficient in other circumstances, such as when a board of directors is captured by an overly powerful CEO or the magnitude of negative special items has been overstated (e.g., by shifting core expenses into special items). This paper explores whether strong governance can explain cross‐sectional variation in compensation shielding, and whether stronger governance and auditing are associated with less shifting of expenses. We find that strong corporate governance mechanisms, as captured by board (and committee) independence, the Sarbanes‐Oxley (2002) Act (SOX) and its related governance reforms, and switches to Big 4 auditors, are all associated with less compensation shielding. While our evidence suggests that strong overall governance is associated with a reduction in manipulation of core earnings through classification shifting in the cross‐section, we find inconclusive evidence to suggest that board independence or SOX influence classification shifting.
Adolescent alcohol exposure decreases frontostriatal resting‐state functional connectivity in adulthood

Published: July 2017

AbstractConnectivity of the prefrontal cortex (PFC) matures through adolescence, coinciding with emergence of adult executive function and top‐down inhibitory control over behavior. Alcohol exposure during this critical period of brain maturation may affect development of PFC and frontolimbic connectivity. Adult rats exposed to adolescent intermittent ethanol (AIE; 5 g/kg ethanol, 25 percent v/v in water, intragastrically, 2‐day‐on, 2‐day‐off, postnatal day 25–54) or water control underwent resting‐state functional MRI to test the hypothesis that AIE induces persistent changes in frontolimbic functional connectivity under baseline and acute alcohol conditions (2 g/kg ethanol or saline, intraperitoneally administered during scanning). Data were acquired on a Bruker 9.4‐T MR scanner with rats under dexmedetomidine sedation in combination with isoflurane. Frontolimbic network regions‐of‐interest for data analysis included PFC [prelimbic (PrL), infralimbic (IL), and orbitofrontal cortex (OFC) portions], nucleus accumbens (NAc), caudate putamen (CPu), dorsal hippocampus, ventral tegmental area, amygdala, and somatosensory forelimb used as a control region. AIE decreased baseline resting‐state connectivity between PFC subregions (PrL‐IL and IL‐OFC) and between PFC‐striatal regions (PrL‐NAc, IL‐CPu, IL‐NAc, OFC‐CPu, and OFC‐NAc). Acute ethanol induced negative blood‐oxygen‐level‐dependent changes within all regions of interest examined, along with significant increases in functional connectivity in control, but not AIE animals. Together, these data support the hypothesis that binge‐like adolescent alcohol exposure causes persistent decreases in baseline frontolimbic (particularly frontostriatal) connectivity and alters sensitivity to acute ethanol‐induced increases in functional connectivity in adulthood.
A better model of care after surgery for early endometrial cancer – Comprehensive needs assessment and clinical handover to a woman's general practitioner
Authors: Rio Ines M. , McNally Orla 
Published: July 2017

BackgroundEndometrial cancer is the most common invasive gynaecological cancer in Australia. Despite the fact that review after treatment of early endometrial cancer has not been shown to detect recurrent disease, practice at several hospitals brings women back for specialist hospital review for 5 years after definitive cancer surgery.AimImplement an improved model of follow‐up care following hospital treatment for early endometrial cancer.Evaluation MethodsQuantitative and qualitative.ResultsSeventy‐three of the eligible 81 women undertook the model of care. All general practitioners (GPs) agreed to follow‐up care. Thirty‐one women (42%) and 37 GPs (51%) returned surveys. All women found the nurse consultation very useful or useful with 77% reporting making lifestyle changes and 87% found the GP consultation very useful or useful with 72% reporting making lifestyle changes. Eighty‐nine percent of GPs found the care plan useful, 94% set up patient recall systems, 79% used the care plan to develop their own care plan, 100% felt confident in providing follow‐up care with 91% reporting the care plan and hospital processes improved their confidence. Comparison with the pre‐cohort women showed: higher rates of communication at various care points to GPs (from P < 0.001); more referrals (P < 0.001); and a projected decrease of nine hospital doctor appointments per patient.DiscussionWith an increasing number of people surviving cancer, in order to address holistic health needs and maintain tertiary service capacity, general practice will be required to provide more follow‐up care. Our model demonstrates an acceptable and quality mechanism for this to occur.

Published: July 2017

AbstractLiver fibrosis is a common response to many chronic liver diseases. The aim of our study was to explore whether pharmacotherapy for concurrent diseases affects overall mortality, liver‐related mortality and liver‐related morbidity in patients with chronic liver disease. We performed a register‐based cohort study of all patients with a first‐time diagnosis of chronic liver disease between 2005 and 2012 in Sweden (n = 70 546). Data from the Patient Register, the Prescribed Drug Register and the Death Certificate Register were linked. We studied whether the use of statins, angiotensin‐converting enzyme inhibitors, angiotensin receptor blockers and antibiotics affected the risk of total mortality, liver‐specific mortality and morbidity. We found a reduction in mortality risk for statin users (n = 11,245) with hazard ratios from 0.57 (95% CI: 0.32–0.99) for patients with autoimmune hepatitis to 0.84 (95% CI: 0.75–0.95) for patients with alcoholic liver disease. There was a significantly reduced liver‐related mortality for patients with alcoholic liver disease who used angiotensin‐converting enzyme inhibitors, 0.85 (95% CI: 0.65–0.96). There were increased overall mortality risks for antibiotic users (n = 44,572), with hazard ratios up to 1.67 (95% CI, 1.55–1.80) for viral hepatitis. Statin use was associated with decreased risks of liver‐specific mortality and morbidity, and reduced total mortality foremost among patients with alcoholic liver disease. Angiotensin ‐converting enzyme inhibitors was associated with reduced liver‐related mortality among patients with alcoholic liver disease.

Published: July 2017

ObjectiveThe aim of the study was to assess the left ventricular (LV) synchronicity in pregnant women and to identify the main determinants of LV dyssynchrony in asymptomatic pregnant women.MethodsOne hundred sixty‐seven pregnant women consecutively and 48 age‐matched nonpregnant controls were enrolled. For the assessment of LV systolic dyssynchrony, the standard deviation of the time from QRS onset to peak systolic (Tps‐LV‐ standard deviation [SD]) velocity and the maximal difference of the time from QRS onset to peak systolic velocity (Tps‐LV) from 12 segments at the apical views. For the LV diastolic dyssynchrony, the standard deviation of the time from QRS onset to peak diastolic (Tpe‐LV‐SD) velocity and the maximal difference of the time from QRS onset to peak diastolic velocity (Tpe‐LV) were calculated.ResultsBoth systolic and diastolic dyssynchrony indexes were significantly higher in pregnant women than in the normal controls (Tps‐LV; P<.01, Tps‐LV‐SD; P<.03, Tpe‐LV, P<.05 and Tpe‐LV‐SD; P<.02). A total of 28 (16.8%) of the pregnant women had a dyssynchrony index above the accepted value for LV dyssynchrony (>34.4 msec). There was a significant correlation between LV dyssynchrony indexes with, multiparty, multifetal pregnancies, systolic blood pressure in pregnant women with LV dyssynchrony. Additionally LV dyssynchrony was significantly associated with elevated E/e” and brain natriuretic peptide (BNP).ConclusionsBoth systolic synchronicity and diastolic synchronicity were affected in pregnant women compared to nonpregnant women. LV dyssynchrony was significantly correlated with age, multiparity, and BNP level. Early detectable changes in systolic and diastolic synchrony may be present in pregnant women at higher risk of peripartum cardiomyopathy.
Cell‐free DNA — Minimally invasive marker of hematological malignancies

Published: July 2017

AbstractAlthough tumor cells are the most reliable source of tumor DNA, biopsy of the tumor is an invasive procedure that should be avoided in some cases. The main limitation of any biopsy is sampling of one tumor site, which may not represent all malignant clones due to the heterogeneity of the tumor. These clones respond to treatment differently and thus directly influence survival of the patient. Circulating cell‐free DNA (cfDNA) is released from multiple tumor sites, reflects overall heterogeneity of the tumor, and correlates with its progression. Detection of tumor‐specific genetic and epigenetic aberrations in cfDNA could have a direct impact on molecular diagnosis, prognosis, follow‐up of disease, monitoring of minimal residual disease, and response to treatment. While most cfDNA data are still experimental, they are very promising. This review focuses on cfDNA in hematological malignancies.

Published: July 2017

AbstractPreservation properties of soy protein isolate (SPI)/nano‐SiOx composite coatings to apple fruits were investigated. The sodium dodecyl sulfonate‐modified nano‐SiOx (SNS) particles were prepared by the ultrasonic method and the counter‐ion activation method, which products were designated as USNS and CSNS, respectively. The incorporation of CSNS particles was better than USNS to improve the preservation quality of the SPI film. The best conditions for the synthesis of the composite film were as follows: 10% SPI concentration, 0.3% nano‐SiOx dosage and coating time of 60 s. Under these conditions, the climacteric peak of apples was delayed to the fifth week. The apples also had better physiological indices than the control group. Nano‐SiOx particles were inlaid and evenly dispersed into the SPI film coatings. This work provides a simple CaCl2 pre‐activation method to produce SPI film coatings with good dispersion of nano‐SiOx particles for further preservation application of fresh fruits.
