OBJECTIVES This study identified perceived employability trajectories and their associations with sleeping difficulties and depressive symptoms over time. METHODS The sample was part of the Swedish Longitudinal Survey on Health from 2008 to 2014 (n=4,583). RESULTS Two stable trajectories (high and low perceived employability over time) and three trajectories with changes (increasing, decrea...

the main purpose of the present research is to determine the relationship between the management earnings forecast errors and conservatism level and then surveying about the effects of forecast difficulty, and external financing on this relationship. regarding this, the financial information related to 147 stock firms, available during the period of study (2003-2015) were collected and analyzed...

calving records from april 1998 to september 2006 comprising 104,572 calving events from 16 dairy herds of iran were used to analyze the potential effect of dystocia on calf stillbirth and productive traits in iranian holsteins. statistical analyses of production traits were performed using a linear mixed model procedure. also, a logistic regression model was constructed to analyze the effect o...

The objective of this study was to evaluate the economic and humanistic burden of chronic sleep maintenance insomnia characterized by nighttime awakenings (CINA). A database analysis of National Health and Wellness Survey, an annual cross-sectional study of health status and outcomes of US adults, was performed. CINA was defined as experiencing nighttime awakenings at least twice per week for m...

Recent studies on the acquisition of putative “relative clauses” (RCs) in East Asian languages have raised the question of whether the Noun Phase Accessibility Hierarchy (NPAH, or AH) (Keenan & Comrie, 1977) is applicable to those languages. In this paper, I report findings from Chinese as a foreign language learners‟ production data in a sentence combination task. Results from this experiment ...

STUDY OBJECTIVES This study aimed to investigate the role of social factors, especially social support for sleep, among victims living at home around 1-2 years after the Great East Japan Earthquake and tsunami. DESIGN A cross-sectional household survey was conducted between May and December 2012 (14-21 months after the disaster) in the Ishinomaki area, Japan. Univariate and multivariate logis...

While the applications of computational fluid dynamics are pervasive throughout applied science and engineering, ranging from astrophysics to the design of cooling systems for semi-conductors, its role in aircraft design is crucial to an unusual extent, because of the narrow margins within which aircraft can operate efficiently. If computational aerodynamics is to be truly effective in the desi...

In this paper, a systematic comparison of various evolutionary approaches to multiobjective optimization using six carefully chosen test functions is given. Each test function involves a particular feature that is known to cause difficulty in the evolutionary optimization process, mainly in converging to the Pareto-optimal front (e.g., multimodality and deception). By investigating these differ...

We investigate the complexity of bounding the uncertainty of graphical games, and we provide new insight into the intrinsic difficulty of computing Nash equilibria. In particular, we show that, if one adds very simple and natural additional requirements to a graphical game, the existence of Nash equilibria is no longer guaranteed, and computing an equilibrium is an intractable problem. Moreover...
