Orbit improvement of the satellites of the outer planets
Data reduced from 127 plates showing Jupiter's and Saturn's satellites in the interval 1972 to 1974 are available on computer cards in the form of (O-C) residuals. Initial orbit calculations and several later orbit improvements for Jupiter XIII (Leda) culminated in an extended ephemeris for Leda to the year 2000. The possible existence of several small satellites just outside Saturns rings was predicted. De Sitter's incomplete theory for the motion of the Galilean satellites was reviewed and an outline for a revised, complete theory was developed. Observations of nearly 100 relative positions of the Galilean satellite with a mean accuracy of about 100 km (0.03 arc sec) were used to improve Sampson's theory for these satellites. Results were published on (1) a long term upper limit to Jupiter's orbital eccentricity; (2) deviation of an accurate modern value of the ellipticity of Uranus from balloon-borne images and consequent evaluation of the planet's rotation rate; and (3) identification of features in Saturn's rings as produced by heretofore undetected tesseral harmonics of Saturn's gravitational field
Semantics in Cultural Perspective Overview
The article was to aim to investigate the semantics overview based on the cultural perspective. The aim of semantics is to discover why meaning is more complex than simply the words formed in a sentence. Culture is a word for the \u27way of life\u27 of groups of people, meaning the way they do things. The excellence of taste in the fine arts and humanities, also known as high culture. An integrated pattern of human knowledge, belief, and behavior. The outlook, attitudes, values, morals, goals, and customs shared by a society. Culture is the characteristics and knowledge of a particular group of people, encompassing language, religion, cuisine, social habits, music, and arts. The word "culture" derives from a French term, which in turn derives from the Latin "colere," which means to tend to the earth and grow, or cultivation and nurture. Well, cultural tradition can take on many forms. A tradition is usually some kind of action or event that is passed on through the generations of a certain group that practices said traditions. So WE would guess that cultural tradition is where a group of people practices certain traditions from a culture. Cultural values are the core principles and ideals upon which an entire community exists. This is made up of several parts: customs, which are traditions and rituals; values, which are beliefs; and culture, which is all of a group\u27s guiding values
LIDA: A Working Model of Cognition
In this paper we present the LIDA architecture as a working model of cognition. We argue that such working models are broad in scope and address real world problems in comparison to experimentally based models which focus on specific pieces of cognition. While experimentally based models are useful, we need a working model of cognition that integrates what we know from neuroscience, cognitive science and AI. The LIDA architecture provides such a working model. A LIDA based cognitive robot or software agent will be capable of multiple learning mechanisms. With artificial feelings and emotions as primary motivators and learning facilitators, such systems will ‘live’ through a developmental period during which they will learn in multiple ways to act in an effective, human-like manner in complex, dynamic, and unpredictable environments. We discuss the integration of the learning mechanisms into the existing IDA architecture as a working model of cognition
Relatively computably enumerable reals
A real X is defined to be relatively c.e. if there is a real Y such that X is
c.e.(Y) and Y does not compute X. A real X is relatively simple and above if
there is a real Y <_T X such that X is c.e.(Y) and there is no infinite subset
Z of the complement of X such that Z is c.e.(Y). We prove that every nonempty
Pi^0_1 class contains a member which is not relatively c.e. and that every
1-generic real is relatively simple and above.Comment: 5 pages. Significant changes from earlier versio
Can the Heinrich ratio be used to predict harm from medication errors?
The purpose of this study was to establish whether, for medication errors, there exists a fixed Heinrich ratio between the number of incidents which did not result in harm, the number that caused minor harm, and the number that caused serious harm. If this were the case then it would be very useful in estimating any changes in harm following an intervention. Serious harm resulting from medication errors is relatively rare, so it can take a great deal of time and resource to detect a significant change. If the Heinrich ratio exists for medication errors, then it would be possible, and far easier, to measure the much more frequent number of incidents that did not result in harm and the extent to which they changed following an intervention; any reduction in harm could be extrapolated from this
Stakeholder capitalism, corporate governance and firm value
We consider the advantages and disadvantages of stakeholder-oriented firms that are concerned with employees and suppliers as well as shareholders compared to shareholder-oriented firms. Societies with stakeholder-oriented firms have higher prices, lower output, and can have greater firm value than shareholder-oriented societies. In some circumstances, firms may voluntarily choose to be stakeholder-oriented because this increases their value. Consumers that prefer to buy from stakeholder firms can also enforce a stakeholder society. With globalization entry by stakeholder firms is relatively more attractive than entry by shareholder firms for all societies. JEL Classification: D02, D21, G34, L13, L2
Dream Sequence
I had the strangest dream last night, I deamt that I was flying over Washington, D.C. toward the White House. As I passed the front gates, I could see a line of picketers pacing back and forth, back and forth, back and forth. The pacing got me so dizzy that i could hardly tell which way was back and which was way forth! They were shouting something about the Attorney General, who was refusing to leave office despite mounting evidence against him and continuing calls for his resignation. I caught a glimpse of one of their signs and I flew by them
