This paper introduces a double and group acceptance sampling plans based on time truncated lifetimes when the lifetime of an item follows the inverse log-logistic (ILL) distribution with known shape parameter. The operating characteristic function and average sample number (ASN) values of the double acceptance sampling inspection plan are provided. The values of the minimum number of groups and operating characteristic function for various quality levels are obtained for a group acceptance sampling inspection plan. A comparative study between single acceptance sampling inspection plan and double acceptance sampling inspection plan is carried out in terms of sample size. One simulated example and four real-life examples are discussed to show the applicability of the proposed double and group acceptance sampling inspection plans for ILL distributed quality parameters.  相似文献

The authors examine 12 months of emergency department visit data (N= 2,521) from the National Electronic Injury Surveillance System All Injury Program and explore its utility for measuring and studying intimate partner violence. Given the dearth of national data on intimate partner violence–related injury and its potential value for public health surveillance and prevention, the data set appears promising for estimating national rates of emergency department visits. Missing perpetrator‐patient relationship data limit estimation of intimate partner–related hospital visits for injury and pain, which precludes national rate estimation at this time, but the data are still useful for describing documented intimate partner violence cases and may be helpful in designing prevention strategies.  相似文献

The recent mini scandal surrounding questionable on-line postings of John Mackey, the founder and CEO of Whole Foods Market Inc., raises once again ethical challenges related to contemporary business leadership. Given his visible commitment to environmentally sound strategies and other responsible business practices, Mackey’s actions epitomize the irony and paradox that can surround executive leadership ethics. While this essay acknowledges the potential role of stricter legal constraints, punishments for offenders, decentralized governance systems, and rationalized structures that help prohibit power abuse, it views such rationalistic considerations alone to be inadequate. Rather, the authors suggest that the promotion of authentic virtuousness is an often overlooked yet indispensable part of any meaningful long term ethical leadership process.  相似文献

Many wireless communication problems is based on a convex relaxation of the maximum likelihood problem which further can be cast as binary quadratic programs (BQPs). The two standard relaxation methods that are widely used for solving general BQPs such as spectral methods and semidefinite programming problem (SDP), each have their own advantages and disadvantages. It is widely accepted that small and medium sized SDP problems can be solved efficiently by interior point methods. Albeit, semidefinite relaxation has a tighter bound for large scale problems, but its computational complexity is high. However, Row-by-Row method (RBR) for solving SDPs could be opted for an alternative for large-scale MIMO detection because of low complexity. The present work is a spectral SDP-cut formulation to which the RBR is applied for large-scale MIMO detection. A modified RBR algorithm with tighter bound is presented to specify the efficiency in detecting massive MIMO.  相似文献

Hand tool mechanisms designed to reduce the risk factors have rarely been studied. In this paper it is analyze trowel firstly designing in CATIA and then its Finite Element Analysis has been carried out by ABAQUS. The main emphasis is on finding stresses by using this software, then removing them by suitable mechanical working on tool & ergonomic change in the design of handle to make it more comfortable. Body part discomfort score and overall discomfort rating experienced by the subjects had also been estimated. During the muscular activity workers physiological responses i.e. energy expenditure rate, oxygen consumption rate and heart rate increases. This increase in physiological responses is related to the type, intensity and duration of work and thus sets limits to the performance of heavy work. In this paper oxygen consumption rate and heart rate was used for physiological cost estimation. These parameters were measured by Computerized Ambulatory Metabolic Measurement System K4b2.  相似文献

This paper synthesizes insights from new global data on the effectiveness of migration policies. It investigates the complex links between migration policies and migration trends to disentangle policy effects from structural migration determinants. The analysis challenges two central assumptions underpinning the popular idea that migration restrictions have failed to curb migration. First, post‐WWII global migration levels have not accelerated, but remained relatively stable while most shifts in migration patterns have been directional. Second, post‐WWII migration policies have generally liberalized despite political rhetoric suggesting the contrary. While migration policies are generally effective, “substitution effects” can limit their effectiveness, or even make them counterproductive, by geographically diverting migration, interrupting circulation, encouraging unauthorized migration, or prompting “now or never” migration surges. These effects expose fundamental policy dilemmas and highlight the importance of understanding the economic, social, and political trends that shape migration in sometimes counterintuitive, but powerful, ways that largely lie beyond the reach of migration policies.  相似文献

This research draws on a unique, large dataset of individuals in Croatia regarding their corruption experiences to analyze determinants of bribe payments. Taking account of economic, personal, social and geographic factors, results show that while greater competition for favors makes bribe offers more likely, females are less likely to offer bribes. A larger government size seems more focused on strengthening checks and balances rather than lengthening red tape. Robustness checks generally support these results.  相似文献
