An assessment of stress and production rate of sucker rod heat pipes in oil well pumping system
Deep Underground Science and Engineering, EarlyView.The sucker rod pumping system is the preferred oil extraction technique. The concept about equipping the hollow vacuum space in solid sucker rods with heat pipe has been scrutinized in terms of stress and oil production evaluation. Abstract The implementation of the heat pipe concept in sucker rods for oil pumping systems negates the requirement for an

A Condition Under Which the Pitman and Bahadur Approaches to Efficiency Coincide
The Annals of Statistics, 1976 The approximate Bahadur efficiency and the Pitman efficiency for hypothesis testing problems are considered. A theorem is stated and proved which gives a condition under which the existence of the limiting (as the alternative approaches the hypothesis) approximate Bahadur efficiency implies the existence of the limiting (as the significance level ...

Pitman Efficiencies of Sequential Tests and Uniform Limit Theorems in Nonparametric Statistics
The Annals of Statistics, 1978 In this paper Pitman's method of constructing and comparing tests based on statistics which are asymptotically normal under the null hypothesis and the local alternatives is extended to sequential tests of statistical hypotheses. The asymptotic normality assumption in Pitman's theory is replaced in its sequential analogue by the weak convergence of ...

Talent Management in SMEs: Unraveling the Role of Contextual Factors
Human Resource Development Quarterly, EarlyView.ABSTRACT Employing a multiple case study analysis, this paper explores the contextual factors—internal, external, and relational—that affect small and medium‐sized enterprises (SMEs) in designing their approaches to talent management (TM). Results underscore the significance of two prominent internal variables—namely, organizational size and ownership ...

On nonparametric and semiparametric testing for multivariate linear time series
, 2009 We formulate nonparametric and semiparametric hypothesis testing of multivariate stationary linear time series in a unified fashion and propose new test statistics based on estimators of the spectral density matrix.

The impact of predation by marine mammals on Patagonian toothfish longline fisheries [PDF]
, 2015 Predatory interaction of marine mammals with longline fisheries is observed globally, leading to partial or complete loss of the catch and in some parts of the world to considerable financial loss.

Work Has Changed, Has HRM? Designing for the Distributed, Fragmented, and Fluid Era
Human Resource Management, EarlyView.ABSTRACT This paper addresses the growing misalignment between traditional human resource management (HRM) systems and the realities of distributed, fluid, and fragmented work. To address this issue, we introduce the FLUID‐HRM framework—a layered design architecture that reconfigures core HRM domains (resourcing, rewards, development, relations, work ...

On the limiting Pitman asymptotic relative efficiency of two Cramér-von Mises tests
, 2013 The Cramér-von Mises test is one of the classical goodness-of-fit tests, for simple as well as for composite null hypotheses. In the classical theory of independent and identically distributed data the corresponding test statistic is based on the empirical distribution function, which is well known to be the nonparametric maximum likelihood estimator ...

On the limiting Pitman efficiency of some rank tests of independence
Journal of Multivariate Analysis, 1986 Kendall's tau and Spearman's rho may be expressed by the use of standard sequences with parameter \(a=1\). The paper uses the fact that the main assumption of \textit{H. S. Wieand}'s theorem [Ann. Stat. 4, 1003-1011 (1976; Zbl 0351.62033)] may be replaced by an equivalent one which is presented in section 2.
