The Association between Social Support Sources and Cognitive Function among Community-Dwelling Older Adults: A One-Year Prospective Study

There is evidence that social relationships may modify cognitive decline in older people. We examined the prospective association between social support and cognitive function among community-dwelling older people. Japanese adults recruited at health checkups in suburban towns were surveyed at baseline and one-year follow-up. Cognitive function was assessed using the Montreal Cognitive Assessment, Japanese version (MoCA-J). Social support from coresiding family, non-coresiding family, and neighbors/friends was assessed using self-administered questionnaires. Multivariable linear regression analysis was conducted to examine the effects of social support on MoCA-J scores at follow-up. Data were analyzed from 121 older people (mean age (standard deviation): 73.86 (4.95) years). There was a positive association between social support exchanges with neighbors and friends and MoCA-J scores at follow-up after covariate adjustment (unstandardized β = 1.23, p = 0.006). Social support exchanges with coresiding family and non-coresiding family and relatives were not associated with MoCA-J scores at follow-up (coresiding family: Unstandardized β = 0.28, p = 0.813, non-coresiding family and relatives: Unstandardized β = 0.51, p = 0.238). The provision of emotional support to neighbors and friends had the largest effect on MoCA-J scores. Our findings suggest that social support exchanges with neighbors and friends are protective against cognitive decline.
Earnings Management Around Initial Public Offerings: Borsa Istanbul Application

This paper studies the presence of earnings management in initial public offerings (IPOs) of Turkish firms. The sample consists of 30 Turkish firms that went public in the years 2011 to 2015 on the Borsa Istanbul. Since there is no market-determined price for IPO share before they are sold to market participants by issuers and underwriters, increasing the attractiveness of an IPO share will be related the degree of earnings management before going public. Therefore this paper aims to find whether IPO issuers make discretionary accruals in their financial statements in order to affect the IPO share price before, during and after going public. According to the results, discretionary accruals level is the highest in the IPO year which is expected as in the other studies and there is statistically significant difference between different periods.
HPC Predictions of Primary Atomization with SPH : Validation and Comparison to Experimental Results

The prediction of atomization is associated to extremely high numerical costs and requires a very accurate modeling of the involved physical processes. State of the art Eulerian multi-phase simulation methods failed to reliably predict the spray characteristics of air-assisted atomizers. In this paper we qualitatively and quantitatively evaluate the capabilities of the SPH method with respect to its applicability to this multiscale phenomenon. By means of 2D simulations of a generic airblast atomizer, we compare the SPH spray predictions with the results obtained by commonly used Eulerian multiphase methods. Furthermore, the convergence behavior of SPH has been investigated by varying the spatial resolution by a factor of 20. The convergence criterion is the appearance of droplets consisting of a single particle. It can be shown, that the convergence rate follows a power law. A 3D simulation consisting of 1.2 billion particles is compared to the results from experimental investigations. The simulation is capable to phenomenologically predict the experimentally observed breakup mechanisms. Knowing, that the small number of simulated breakup events does not allow any statistically significant statement, we observe, that the numerically predicted characteristic and mean fuel droplet sizes coincide with the experimentally measured droplet sizes.
Effect of errors in genetic and environmental variances on the BLUP estimates of sire breeding values

Summary — The BLUP method for the estimation of breeding values requires the knowledge of the ratio of the residual over the genetic variance or of the heritability value (hThe bias in the breeding value estimates caused by a wrong choice of h has been examined by: (a) analysis of 11 populations simulated by varying the h value of the trait and the offspring size of each sire (n); (b) analysis of the weaning weights of 2055 Angus beef calves (725 dams bred to 89 sires). The breeding value estimates were found to be different depending on the h value chosen. This error causes rank changes between sires and, consequently, a possible wrong choice of the subjects to be selected. For a 40% error in h and 5 < n < 60, we found that the % bias : 26.2 + 47.9/n- 27.9irWhen the data structure makes a serious bias likely to occur in the breeding value estimates, it is recommended to use a method for the variance components estimation, even if this is more time consuming from a computing point of view.
Capital Outflows and Unemployment: A Panel Analysis of OECD Countries

Liberalization of trade and payment regimes after the mid-1980s expedited capital outflows, especially from developing countries toward developed ones. This inevitable trend has given rise to new discussions among scholars regarding the real effect of capital movements abroad on the domestic labor market. However, the debate is ambiguous and ongoing. Thus, the main objective of this study is to determine the relationship between capital outflows and employment levels in the home country from 2006¨C2013 in 30 Organization for Economic Co-operation and Development (OECD) countries. We have employed dynamic panel data methods to capture the causal relationship between capital outflows and employment levels. Finally, our empirical predictions show that capital outflows lead to a reduction in employment levels in the home market, whereas a larger market size leads to an increase in the employment levels.
Surgery vs conservative treatment for type II and III odontoid fractures in a geriatric population

Abstract Background: It is unclear whether surgery or conservative treatment is more suitable for elderly patients with type II and type III odontoid fractures. We performed this meta-analysis to compare the efficacy of surgical and conservative treatments for type II and type III odontoid fractures. Methods: A literature search was performed in PubMed, Embase, Web of Science, and Cochrane Library in January 2017. Only articles comparing surgery with conservative treatment in elderly patients with type II and type III odontoid fractures were selected. After 2 authors independently assessed the retrieved studies, 18 articles were included in this meta-analysis, and the primary endpoints were the nonunion rate and mortality rate. The secondary outcomes were patient satisfaction, complications, and the length of the hospital stay. The quality of the included studies was evaluated using the modified Newcastle–Ottawa scale. Sensitivity analyses were performed for high-quality studies, and the publication bias was evaluated using a funnel plot. Results: Lower nonunion (odds ratio [OR]: 0.27, 95% confidence interval [CI]: 0.18–0.40, P < .05) and mortality rates (OR: 0.52, 95% CI: 0.34–0.79, P < .05) confirmed the superiority of surgery in treating type II and type III fractures. The secondary outcomes differed. Patients in the surgery group felt more satisfied with the outcome (OR: 3.44, 95% CI: 1.19–9.95, P < .05), and the complications were similar in the 2 groups (OR: 1.14, 95% CI: 0.78–1.68, P = .5), whereas patients in conservative groups spent less time in the hospital (OR: 5.10, 95% CI: 2.73–7.47, P < .05). The results of the subgroup analyses and sensitivity analysis were similar to the original outcomes, and no obvious publication bias was observed in the funnel plot. Conclusion: Most elderly (younger than 70 years) patients with type II or type III odontoid fractures should be considered candidates for surgical treatment, due to the higher union rate and lower mortality rate, while statistically significant differences were not observed in the population with an advanced age (older than 70 years). Therefore, the selection of the therapeutic approach for elderly patients with odontoid fractures requires further exploration. Simultaneously, based on our meta-analysis, a posterior arthrodesis treatment was significantly superior to the anterior odontoid screw treatment.

ANALYSIS OF CONDITIONAL ASYMMETRIC VOLATILITY OF REAL GDP AND MAIN ECONOMIC SECTORS GROWTH RATES IN IRAN

GDP growth is one of the basic and effective factors of economic growth of country and it is directly so-called economic growth, so we must pay a lot attention to its volatilities. Most empirical studies of economic growth exclude these volatilities and the dimension of conditional volatility shocks. In this paper we search for evidence of conditional volatility in quarterly real GDP of Iran. Furthermore, in order to investigate the basic reasons of these volatilities, we also examined four main economic sectors including agricultural, industrial and mining, oil and service sectors. The widely accepted exponential GARCH model of Nelson is employed to record the possible existence and asymmetric conditional volatility in real GDP and main sectors. The data set are in constant prices and quarterly observation from 1367 Q1 to 1391Q3. The government needs to use these volatilities to implement stabilizing policies which are the new method for analyzing of GDP and help for understanding the existing disturbances and growth rates. In this paper we capture the real GDP volatilities and its main determinants, afterwards it proves that the necessity of well-advised government intervention. As a result of this paper, it is calculated the equation for growth rate variance and persistence and asymmetry are gotten. Also, the negative shocks of GDP have more effects on future values of GDP than positive ones by equal values. Moreover, the results show that oil shocks are the most important reasons of real GDP volatilities. Consequently, for removing the variations, strategic action of government and diminishing the effectiveness of oil are needed. The results can be used for growth and development to achieve an economy with a stable and increasing growth.
Towards Global Optimization of Constant Rebalanced Portfolio (The advances and applications of optimization method)

We address the multi-period portfolio optimization problem with the constant rebalancing strategy. This problem is formulated as a polynomial optimization problem (POP) by using a mean-variance criterion. In order to solve the corresponding POPs of high degree, we develop a cutting-plane algorithm based on semidefinite programming. Our algorithm can solve problems that can not be handled directly by any of known polynomial optimization solvers.
Adults with Loeys–Dietz syndrome and vascular Ehlers–Danlos syndrome: A cross‐sectional study of health burden perspectives

The aim is to study adults with vascular Ehlers–Danlos syndrome (vEDS) and Loeys–Dietz syndrome (LDS) with regard to sociodemographic characteristics, perceived vascular‐ and multi‐organ symptom burdens, and health services utilization. This is a cross‐sectional study. In 2018, a postal questionnaire was sent to 71 individuals with genetically verified LDS types 1–4 or vEDS, age ≥ 18 years, recruited through a National Resource Centre for Rare Disorders in Norway. Eighteen patients with vEDS and 34 patients with LDS subtypes 1‐4 participated, the response rate was 74%. Median age was 43.5 (range 18‐68) years, and 58% were women. Median age at diagnosis was 34 years (range: 6–63). Severe vascular‐ and multi‐organ symptom burdens were found, and chronic pain was reported by 79%. Most respondents (87%) had cardiovascular surveillance visits, 58% yearly or more often, and still 29% had no antihypertensive medications. Three quarters communicated diagnosis‐related concerns with their general practitioner. A considerable group (31%) had left work before retirement age. Healthcare professionals should be aware of the spectrum of health burden in adults with vEDS and LDS. A verification of the diagnosis is crucial to counseling, including medical follow‐up, education, and work, and advices on precaution and life style decisions.
A Review of Ecosystem Service Studies: Concept, Approach and Future Work in Korea

In South Korea, the conflict between development and conservation policy still exist among government ministries, and conventional development plan often has priority over conservation policy. Establishment of sustainable development and comprehensive management policy employing the results of ecosystem service studies are highly warranted, but researchers in South Korea are still limited and often misuse the concept of ecosystem services. Thus, we aimed to introduce the concept of Ecosystem Service (ES) and related terminologies such as Social-Ecological Systems (SESs), ecosystem function, trade-off, and human well-being in this paper. Additionally, this article reviewed and arranged key approaches in ES studies as follows: 1) field works, 2) mapping ecosystem services, 3) valuing ES, 4) quantifying trade-offs between ES and 5) understanding SESs. Based on those results, we suggest that field works for basic information have the first priority to be conducted among ES studies. Once basic information is sufficiently accumulated, researchers can perform applied ES research with accuracy. Finally, results of ES studies conducted by five approaches allow decision makers to consider both natural system and society simultaneously, and hence the results can be utilized for sustainable development and conservation policy based on ecosystem-based management.
Profits from technical analysis: an empirical evidence of precious metal markets

The main objective of this study is to investigate the validity and predictability of technical analysis in precious metal markets. This study applies the bootstrap tests of White (2000) and Hansen (2005) to determine if there are favorable trade rules among the “universe” of technical trading rules of the Sullivan et al. [3] research. This study employs the powerful bootstrap tests to determine the profitability of technical analysis with the restructuring of non-synchronous trading and transaction costs. The empirical results strongly indicate that the three elements, data snooping, nonsynchronous trading and transaction costs, have a significant impact on the overall performance of technical analysis. In fact, these results illustrate that economic profits cannot be generated among the ten precious metal market indices.
What Do We Learn from Two-Dimensional Raman Spectra by Varying the Polarization Conditions?

-order (two-dimensional) Raman spectrum of a liquid can depend dramaticallyon the polarizations of the various light beams, but to date there has been no evidence presented that differentpolarization conditions probe any fundamentally different aspects of liquid dynamics. In order to explore themolecular significance of polarization we have carried out a molecular dynamics simulation of the 5
Fusion between serine-threonine reach domain from STA1 gene with BGLB gene of the Paenibacillus polymyxa.

Beta-glucosidase gene of bacterian origin was cloned in Saccharomyces cerevisiae to enable growth on disaccharide, cellobiose. To promote the secretion of s-glucosidase B, the catalitic domain of bglB gene was fused with the serinethreonine rich domain of the STA1 gene and was inserted into an yeast expression vector under control of the CYCGAL inductible S. cerevisiae promoter. Expression of hybrid gene and proteine secretion was verified in Saccharomyces cerevisiae with p-nitrophenyl-s-D-glucopyranoside as substrate. Genetically stable and regulated expression in Saccharomyces cerevisiae of s-glucosidase activity is interesting for the development of strains able to ferment s-glycosidic sugars (i.e. cellobiose and lactose).
High expression of HSP90 is associated with poor prognosis in patients with colorectal cancer

Background Heat shock protein 90 (HSP90) is a highly conserved chaperone with an approximate molecular weight of 90-kDa. It plays a critical role in maintaining stability and homeostasis of oncoproteins, helping cancer cells living in the unsuitable environmental conditions. The current study aims to inquire the difference of HSP90 expression in tumor tissues and normal tissues, analyze the correlation between HSP90 expression and the prognoses of patients with colorectal cancer (CRC), and investigate its role in CRC preliminarily. Methods Online analysis of HSP90 mRNA levels in different cancers was firstly done in Gene Expression Profiling Interactive Analysis. Then HSP90 expression was determined by immunohistochemistry between 99 CRC tissues and 81 normal tissues. Chi-square test or Fisher’s exact test was used to analyze the relationship between HSP90 and histopathologic characteristics. Kaplan–Meier analysis and Cox’s proportional hazards model were also done for further analysis of the prognostic values of HSP90. Pearson’s correlation coefficients between HSP90 expression values and other mRNA expression values were calculated based on The Cancer Genome Atlas dataset and bioinformatic analysis was done about these screened genes. Results Colorectal cancer tissues showed significantly higher expression of HSP90 than normal tissues (55.6% vs. 3.7%, P < 0.0001). Kaplan–Meier curves showed high HSP90 expression was associated with poor prognosis (P = 0.039) in CRC patients, and multivariate Cox proportional hazards regression model analysis also indicated that HSP90 expression (HR = 1.930, 95% CI [1.113–3.349], P = 0.019) linked to poor prognosis. Moreover, 85 genes were correlated with HSP90, which were involved in metabolic process and enriched in pathways of Proteasome and Base excision repair. Conclusions Our results suggested that HSP90 expression is inversely associated with survival outcomes and could be an independent prognostic factor for CRC patients. It mainly involved in metabolic process and exerted binding and catalytic activities.
Why Do Firms Issue Convertible Bonds? Evidence from the Field

We use in-depth interviews with top corporate executives and a question-conditional analysis of a broader survey sample to examine why companies issue convertible bonds. Our findings suggest that firms use convertibles as an alternative for straight debt, which is deemed too costly or covenant-heavy. Equity tends to be ruled out in a previous step of the security choice process because of perceived stock undervaluation. We obtain considerable evidence for the risk uncertainty theory on convertible issuance, while risk shifting, sequential financing, and backdoor equity theories receive little or no support. Our interviews also highlight the substantial impact of investor demand fluctuations and financial intermediaries on corporate security choices and design.
Dissolution of stone wool fibers with phenol-urea-formaldehyde binder in a synthetic lung fluid.

Mineral wool products, composed of stone wool fibers and organic binder, are used in many construction applications. Among all their beneficial properties, the most important requirement is safety for human health, such as when fibers are inhaled. For determining long term toxicity, biosolubility and biopersistence studies in vitro and in vivo are essential. In vitro fiber dissolution rate, which depends on the medium, fiber composition and the surface available for dissolution, is a key parameter in determining biopersistence of the material in vivo. We investigated how organic binder (phenol-urea-formaldehyde), that can partially shield fiber surfaces from the solution, influences fiber dissolution kinetics in synthetic lung fluid (modified Gamble's solution) at pH 4.5 and temperature 37 ºC, in vitro. Dissolution experiments were made in batch and continuous flow using stone wool fibers with typical insulation product binder amounts (0 - 6 wt. %), applied by the standard industrial process. Dissolution rates were determined from element concentrations in the reacted solution and changes in fiber surface composition and morphology were monitored. Stone wool fiber dissolution was close to stoichiometric and was similar, whether or not the material contained binder. The high dissolution rate (508 ng of fiber/cm2/h) is explained by Al and Fe complexing agents, i.e. citrate and tartrate, in the synthetic lung fluid. The organic binder mainly forms micrometer size discrete droplets on the fiber surfaces rather than a homogeneous thick coating. During in vitro tests, fibers with organic binder preferentially dissolved in the areas free of binder, forming cavities, whereas the untreated fibers dissolved homogeneously. Propagation of cavities undermined the binder droplets, leading to complete fiber dissolution. Thus, presence of organic binder on stone wool fibers, produced by the standard industrial process, had no measurable effect on dissolution rate in synthetic lung fluid containing Al and Fe complexing agents.
