We assess whether the probability of a sample member participating at a particular wave of a panel survey is greater if the same interviewer is deployed as at the previous wave. Previous research on this topic mainly uses non-experimental data. Consequently, a) interviewer change is generally non-random, and b) continuing interviewers are more experienced by the time of the next wave. We design...

This paper derives optimal policies for when to hire, train and layoff employees in service organization when worker productivity appreciates deterministically or stochastically under constant, monotonic, and cyclic service demand. The model, an extension of the machine replacement problem from the engineering economy literature, uses infinite horizon linear programming to produce optimal perso...

In 1991, the Women in Engineering (WIE) Initiative at the University of Washington was funded by the Alfred P. Sloan Foundation to conduct a longitudinal study of undergraduate women pursuing degrees in science or engineering. Cohorts of approximately 100 students have been added to the study each year, for a current total of 672 participants. The objectives are: (a) to determine an accurate me...

Our case study confirms two previous studies demonstrating that a ‘lost’ language can be recovered by hypnosis. These results point to the existence of another type of attrition. Here a distinction is made between this type of attrition of a ‘hidden language’ (HL), that is, one that has not been forgotten but rather has become inaccessible to the speaker, and the traditionally studied attrition...

This paper reviews the surface ablation of early hominin teeth by attrition, abrasion, and erosive dental wear. The occurrence of these lesions is explored in a sample of South African fossil australopithecine dentitions revealing excessive wear. Interpretation of the nature of the dietary components causing such wear in the absence of carious erosion provides insight into the ecology of the Pl...

Second price allpay auctions (wars of attritions) have an evolutionarily stable equilibrium in pure strategies if valuations are private information. I show that for any level of uncertainty there exists a pure deviation strategy close to the equilibrium strategy such that for some valuations the equilibrium strategy has a selective disadvantage against the deviation if the population mainly pl...

There are two varieties of timing games in economics: In a war of attrition, more predecessors helps; in a pre-emption game, more predecessors hurts. In this paper, we introduce and explore a spanning class with rank-order payoffs that subsumes both as special cases. In this environment with unobserved actions and complete information, there are endogenously-timed phase transition moments. We i...

The adaptation of native language construal patterns in second language acquisition" (2014). CUNY Academic Works. First language attrition occurs when a bilingual's native language shows evidence of language change due to the predominant use of a second language. Recent research in rst language attrition has shown that lexical retrieval and word choice are more vulnerable to reduced native lang...

Most linguistic processes acquisition, change, deterioration – take place in and are determined by a complex and multifactorial web of language internal and language external influences. This implies that the impact of each individual factor can only be determined on the basis of a careful consideration of its interplay with all other factors. The present study investigates to what degree a num...

Industries such as Banking and Finance, Healthcare, Hospitality and Technology are currently experiencing high attrition rates. You, as a HR manger or senior management executive, may know some apparent causes for attrition in your company. And you also know the high costs of attrition and the negative impact it has on customer facing scenarios. But how often have you felt that if you had known...
