摘要:Residency programs use electronic portfolios (efolios) to organize data, track resident performance, and sometimes teach and assess lifelong learning (LLL) skills. Published studies on efolios in graduate medical education are mostly descriptions of implementation at individual i...

摘要:Abstract(#br)This paper considers a portfolio selection problem with a quadratic utility of consumption, which is symmetric with respect to a bliss point. At bliss point, the utility function has its maximum value and further consumption lowers the utility. In the presence of inf...

摘要:Abstract(#br) Background(#br)A portfolio of supporting information (SI) reflecting a doctor’s entire medical practice is now a central aspect of UK appraisal for revalidation. Medical revalidation, introduced in 2012, is an assessment of a doctor’s competence and passing res...

摘要:Abstract(#br)In this paper, we mainly study the strong limit theorems for the log-optimal portfolio of the ∗-mixing stock market. First, we establish a strong limit theorem for the log-optimal portfolio of any sequence investment, then we obtain the result that the average ret...

摘要:Abstract(#br)In this paper, we consider the robust portfolio selection problem which has a data uncertainty described by the ( p , w ) $(p,w)$ -norm in the o...

摘要:Abstract In this paper, we consider the robust portfolio selection problem which has a data uncertainty described by the ( p , w ) $(p,w)$ -norm in the objective function. We show that the robust formulation of this problem is equivalent to a linear optimization problem. Moreover...

摘要:Abstract(#br)In this paper a portfolio optimization problem with bounded parameters is proposed taking into consideration the minimax risk measure, in which liquidity of the stocks is allied with selection of the portfolio. Interval uncertainty of the model is dealt with through ...

摘要:Abstract(#br)In this paper, we study an optimal portfolio, consumption-leisure and retirement choice problem for an infinitely lived economic agent with a CES utility function. Using the dynamic programming method, we obtain the value function and optimal investment, consumption,...

摘要:In this study, we present a multi-objective approach based on a mean-variance-skewness-entropy portfolio selection model (MVSEM). In this approach, an entropy measure is added to the mean-variance-skewness model (MVSM) to generate a well‑diversified portfolio. Through a var...

摘要:In this paper, we define the portfolio return as fuzzy average yield and risk as hybrid-entropy and variance to deal with the portfolio selection problem with both random uncertainty and fuzzy uncertainty, and propose a mean-variance hybrid-entropy model (MVHEM). A multi-objectiv...
