TL;DR: In this paper, two characterizations of the exponential distribution are given based on the distributional properties of Xl, m. They assume m is an integer-valued random variable with P(m=k) =p (1-p)k-1, k= 1,2, and 0 < p < 1.
Abstract: Suppose X1, X2, Xm is a random sample of size m from a population with probability density function f(x), x > 0), and let X1, m< × 2, m <… < Xm, m be the corresponding order statistics.

TL;DR: In this paper, the authors focused on contingent versus non-contingent stimulation and their effect on attention and consummatory responses as unlearned features of the infant's interaction with stimuli.
Abstract: Studies of instrumental learning in infants have been concerned with negative transfer between noncontingent and contingent learning experiences, sparking debate about the value of responsive environments and calling for measures beyond operant performance to shed light on the underlying perception of contingency. The present studies focused on contingent versus non-contingent stimulation and their effect on attention and consummatory responses as unlearned features of the infant’s interaction with stimuli. In each experiment the dependent variable was tactile behavior directed toward pictures, and the independent variable was the type of contingency controlling the pictures. In Experiment 1, 12- to 18- month-old infants were tested in the laboratory using a modified discrete-trial operant procedure in which a touch-sensitive video screen served as both a projection surface and a touch-recording device. Infants touched contingent slides significantly more often than noncontingent slides. Experiment 2 extended this effect to fixed-ratio 1 (FR-1) versus fixed-ratio 2 (FR-2) schedules of reinforcement. A second group of 12- to 18-month-old infants showed a similar pattern; they touched the FR-2 slides significantly more often than the FR-1 slides. These findings indicate that factors other than operant behavior vary as a function of the degree of contingency in an instrumental situation, and hint at possible cognitive processes that compare contingency “rules” governing the responsiveness of a changing environment.

TL;DR: Using a reduced-form model, this paper finds abortion and neonatal intensive care availability to be the most important determinants of overall neonatal mortality.
Abstract: This paper explores the determinants of birthweight-specific neonatal mortality rates across States in the U.S. in 1980. We are able to explore the interactions between the determinants and birthweight because of the new data available through the National Infant Mortality Surveillance (NIMS). The NIMS links birth and death certificates for each state, resulting in a data base with race-specific neonatal mortality rates by birthweight, and other characteristics. Using a reduced-form model, we find abortion and neonatal intensive care availability to be the most important determinants of overall neonatal mortality. For whites, the two factors are of approximately equal importance in determining neonatal mortality. For blacks, abortion availability has twice the impact of neonatal inexpensive care. Moreover, our results suggest that neonatal mortality rates could be lowered by policies that reduce the inequality in these health resources across states.

TL;DR: A screening and training program for caregivers who work in children's homes was designed and implemented in an attempt to minimize risk for the employing family, reduce potential liability for the referral agency, and maximize employment opportunities for low-income women.
Abstract: A screening and training program for caregivers who work in children's homes was designed and implemented in an attempt to minimize risk for the employing family, reduce potential liability for the referral agency, and maximize employment opportunities for low‐income women. The use of an extensive clinical interview, a check of public records and a multi‐faceted educational program comprised the selection and training process. It was found that no one screening device could eliminate all risks nor assure a quality caregiver, but multiple screenings were valuable in identifying successful candidates. An open‐ended clinical interview conducted by a multi‐disciplinary team was invaluable in revealing risks and identifying training issues.

TL;DR: The curriculum decision-making perceptions of a pilot sample of 75 American kindergarten through twelfth grade teachers doing graduate work in education were surveyed with a 42 item questionnaire as mentioned in this paper and five interpretable factors were extracted.
Abstract: The curriculum decision‐making perceptions of a pilot sample of 75 American kindergarten through twelfth grade teachers doing graduate work in education were surveyed with a 42 item questionnaire. The first four questions established the demographics of the respondents and the next three items indicated that Americans feel more constrained in making curriculum decisions than their British counterparts. The cross‐cultural comparisons are based on the findings of Doherty & Travers (1984). The final 35 items, adapted from the instrument developed by Doherty & Travers, were subject to a factor analysis. Five interpretable factors were extracted. The factors were labelled (1) External Monitory, (2) External Professional, (3) Internal Professional, (4) Facilitative‐Constraining, and (5) Internal Professional Peers. These factors represented 32 items with three items unassignable to any factors. Interitem reliability of the factors was judged good. Though the British study also extracted five factors (f...

Abstract: The Elements of Artificial Intelligence: an Introduction using LISP is intended (as stated in the preface) for use as the text for an introductory course in artificial intelligence. The author's approach to the subject is stated on the dust jacket (and in the preface, although not as concisely).
TL;DR: In this paper, the use of a two-tiered standard in predatory pricing litigation is proposed, where the first part is designed to determine whether the market is structurally predisposed toward predation, and the second part examines the issue of predatory intent.
Abstract: There is considerable controversy surrounding the legal standards used to detect and prosecute cases involving predatory pricing. This paper recommends the use of a two tiered standard in predatory pricing litigation. The first part of the test is designed to determine whether the market is structurally predisposed toward predation. The second part of the test examines the issue of predatory intent. Flexibility is built into these guidelines by giving the plaintiff an option in terms of the evidentiary burden it must carry. The administrative feasibility of this two tiered proposal is demonstrated in a case study analysis. The case analysis shows that the application of a mechanical price-cost predation rule would have incorrectly resulted in a guilty verdict.
TL;DR: In this article, the first experimental evidence showed how /sup 55/Mn hyperfine data can easily distinguish between binuclear manganese complexes having these mixed valence oxidation states.
Abstract: Binuclear and multinuclear manganese containing enzymes which occur in biology are involved in functions such as hydrogen peroxide decomposition in bacteria and the oxidation of water to oxygen during photosynthesis, respectively. In the case of the water-oxidizing complex, the so-called S/sub 2/ oxidation state has been characterized by EPR spectroscopy to be a mixed valence manganese cluster. This can be produced in two forms. The native form, which is found in active O/sub 2/-evolving samples, is considered to be either tetranuclear or trinuclear in Mn, based upon interpretation of its broad 1500 G-wide 19-line multiline EPR signal and unusual temperature dependence. A partially decoupled form is found in inactivated samples having a narrow width (1345 G), with only 16 lines and a more Curie-like temperature dependence, all features which are found in typical Mn/sup 3 +//M/sup 4 +/ binuclear centers (16-line EPR, spin S = 1/2 ground state). For the native form both different oxidation states and different numbers for the manganese ions in the cluster have been proposed in order to account for the larger spectral width due to the hyperfine interaction with /sup 55/Mn. Both binuclear Mn/sup 2 +//Mn/sup 3 +/ and tetranuclear/sup 4/ 3Mn/sup 3 +//Mn/sup 4more » +/ states have been considered. Notably lacking in this analysis has been EPR data for binuclear complexes in which both types of mixed valence oxidation states, Mn/sup 3 +//Mn/sup 4 +/ and Mn/sup 2 +//Mn/sup 3 +/, are compared within the same ligand system. The present report gives the first experimental evidence showing how /sup 55/Mn hyperfine data can easily distinguish between binuclear manganese complexes having these mixed valence oxidation states.« less
TL;DR: A theoretical information resource management (IRM) model is presented to assist in the process of integrating these spheres as a POB data need and several propositions are noted concerning integrated data structures.
Abstract: The data requirements for a program-oriented budgeting (POB) system stem from all spheres of an educational environment. To assist in the process of integrating these spheres as a POB data need, this article presents a theoretical information resource management (IRM) model. The purpose of an IRM system is to integrate, manage, and control the data contained in a school system’s information system. A properly designed IRM can provide POB decision-makers with reports that contain data from all spheres of the educational environment. Concluding remarks and several propositions are noted concerning integrated data structures.
TL;DR: This paper presents a straight forward procedure that can be used by a decision‐making unit to ensure a more complete diagnosis during problem formulation, and suggests a solution investigation scheme.
Abstract: olving the wrong problem is a common occurrence in business practice This paper presents a straight forward procedure that can be used by a decision‐making unit to ensure a more complete diagnosis during problem formulation, and suggests a solution investigation scheme The basic idea is to avoid wasting precious time treating symptoms instead of problems, and also to gain time during the diagnostic process by starting with a conceptual framework about the nature of problems
TL;DR: In this paper, the authors argue that it is both possible and desirable to tie the presentation of by-product accounting to FASB Concept Statements (specifically, to asset and revenue recognition concepts) and other financial accounting practices to which students are traditionally exposed.
