Variable Substitution Quotes

...you can't rationalize suffering - it's indeterminate - the real unknowable variable God substitutes in...

postmodernist arguments deny an objective reality existing independently from human perception, contending that knowledge is filtered through the prisms of class, race, gender, and other variables. In rejecting the possibility of an objective reality and substituting the notions of perspective and positioning for the idea of truth, postmodernism enshrined the principle of subjectivity.

The three conditions without which healthy growth does not take place can be taken for granted in the matrix of the womb: nutrition, a physically secure environment and the unbroken relationship with a safe, ever-present maternal organism. The word matrix is derived from the Latin for “womb,” itself derived from the word for “mother.” The womb is mother, and in many respects the mother remains the womb, even following birth. In the womb environment, no action or reaction on the developing infant’s part is required for the provision of any of his needs. Life in the womb is surely the prototype of life in the Garden of Eden where nothing can possibly be lacking, nothing has to be worked for. If there is no consciousness — we have not yet eaten of the Tree of Knowledge — there is also no deprivation or anxiety. Except in conditions of extreme poverty unusual in the industrialized world, although not unknown, the nutritional needs and shelter requirements of infants are more or less satisfied. The third prime requirement, a secure, safe and not overly stressed emotional atmosphere, is the one most likely to be disrupted in Western societies. The human infant lacks the capacity to follow or cling to the parent soon after being born, and is neurologically and biochemically underdeveloped in many other ways. The first nine months or so of extrauterine life seem to have been intended by nature as the second part of gestation. The anthropologist Ashley Montagu has called this phase exterogestation, gestation outside the maternal body. During this period, the security of the womb must be provided by the parenting environment. To allow for the maturation of the brain and nervous system that in other species occurs in the uterus, the attachment that was until birth directly physical now needs to be continued on both physical and emotional levels. Physically and psychologically, the parenting environment must contain and hold the infant as securely as she was held in the womb. For the second nine months of gestation, nature does provide a near-substitute for the direct umbilical connection: breast-feeding. Apart from its irreplaceable nutritional value and the immune protection it gives the infant, breast-feeding serves as a transitional stage from unbroken physical attachment to complete separation from the mother’s body. Now outside the matrix of the womb, the infant is nevertheless held close to the warmth of the maternal body from which nourishment continues to flow. Breast-feeding also deepens the mother’s feeling of connectedness to the baby, enhancing the emotionally symbiotic bonding relationship. No doubt the decline of breast-feeding, particularly accelerated in North America, has contributed to the emotional insecurities so prevalent in industrialized countries. Even more than breast-feeding, healthy brain development requires emotional security and warmth in the infant’s environment. This security is more than the love and best possible intentions of the parents. It depends also on a less controllable variable: their freedom from stresses that can undermine their psychological equilibrium. A calm and consistent emotional milieu throughout infancy is an essential requirement for the wiring of the neurophysiological circuits of self-regulation. When interfered with, as it often is in our society, brain development is adversely affected.

The actual issue is that someone a hundred thousand years ago sat up in his robes and said Holy Shit. Sort of. He didn’t have a language yet. But what he had just understood is that one thing can be another thing. Not look like it or act upon it. Be it. Stand for it. Pebbles can be goats. Sounds can be things. The name for water is water. What seems inconsequential to us by reason of usage is in fact the founding notion of civilization. Language, art, mathematics, everything. Ultimately the world itself and all in it.

In a seminal 1981 paper, the economist Sherwin Rosen worked out the mathematics behind these “winner-take-all” markets. One of his key insights was to explicitly model talent—labeled, innocuously, with the variable q in his formulas—as a factor with “imperfect substitution,” which Rosen explains as follows: “Hearing a succession of mediocre singers does not add up to a single outstanding performance.” In other words, talent is not a commodity you can buy in bulk and combine to reach the needed levels: There’s a premium to being the best. Therefore, if you’re in a marketplace where the consumer has access to all performers, and everyone’s q value is clear, the consumer will choose the very best. Even if the talent advantage of the best is small compared to the next rung down on the skill ladder, the superstars still win the bulk of the market.

Comparison between the Mithraic and the Christian sacrifice should show just where the superiority of the Christian symbol lies: it lies in the frank admission that not only has man’s animal instinctuality (symbolized by the bull) to be sacrificed, but the entire natural man, who is more than can be expressed by his theriomorphic symbol. Whereas the latter represents animal instinctuality and utter subjection to the law of the species, the natural man means something more than that, something specifically human, namely the ability to deviate from the law, or what in theological language is known as the capacity for “sin.” It is only because this variability in his nature has continually kept other ways open that spiritual development has been possible for Homo sapiens at all. The disadvantage, however, is that the absolute and apparently reliable guidance furnished by the instincts is displaced by an abnormal learning capacity which we also find in the anthropoid apes. Instead of instinctive certainty there is uncertainty and consequently the need for a discerning, evaluating, selecting, discriminating consciousness. If the latter succeeds in compensating the instinctive certainty, it will increasingly substitute reliable rules and modes of behaviour for instinctive action and intuition. There then arises the opposite danger of consciousness being separated from its instinctual foundations and of setting up the conscious will in the place of natural impulse.

The five letters of the SOLID acronym stand for: Single Responsibility Principle: a class should have one and only one responsibility; that is, only one reason to change. The Lack of Cohesion Of Methods metric indicates the antipattern of too large a class. Open/Closed Principle: a class should be open for extension, but closed against modification. The Case Statement design smell suggests a violation. Liskov Substitution Principle: a method designed to work on an object of type T should also work on an object of any subtype of T. That is, all of T’s subtypes should preserve T’s “contract.” The refused bequest design smell often indicates a violation. Dependency Injection Principle: if two classes depend on each other but their implementations may change, it would be better for them to both depend on a separate abstract interface which is “injected” between them. Demeter Principle: a method can call other methods in its own class, and methods on the classes of its own instance variables; everything else is taboo. A design smell that indicates a violation is inappropriate intimacy.

AMERICAN WHEAT OR RYE BEER Refreshing wheat or rye beers can display more hop character and less yeast character than their German cousins. This is a beginner-level style that can be brewed by extract or all-grain methods. Ferments at 65° F (18° C). OG FG IBU Color Alcohol 1.040-1.055 (10-13.6 °P) 1.008-1.013 (2.1-3.3 °P) 15-30 3-6 SRM 6-12 EBC 4-5.5% ABV 3.2-4.3% ABW Keys to Brewing American Wheat or Rye Beer: This easy-drinking beer style usually has a subtly grainy wheat character, slightly reminiscent of crackers. The hop flavor and aroma are more variable, with some versions having no hop character, while others have a fairly noticeable citrus or floral flair. Even when the hops are more prominent, they should not be overwhelming, and the hop bitterness should be balanced. The rye version of this style has a slight spicy, peppery note from the addition of rye in place of some or all of the wheat. The key mistake many brewers make is in assuming that American wheat beer should be similar to German hefeweizen. However, this style should not have the clove and banana character of a hefeweizen. This beer should not be as malty (bready) as a German hefeweizen, either, so all-grain brewers will want to use a less malty American two-row malt. To get the right fermentation profile, it is important to use a fairly neutral yeast strain, one that doesn’t produce a lot of esters like the German wheat yeasts do. While you can substitute yeast like White Labs WLP001 California Ale, Wyeast 1056 American Ale, or Fermentis Safale US-05, a better choice is one that provides some crispness, such as an altbier or Kölsch yeast, and fermentation at a cool temperature. RECIPE: KENT'S HOLLOW LEG It was the dead of winter and I was in Amarillo, Texas, on a business trip with Kent, my co-worker. That evening at dinner I watched as Kent drank a liter of soda, several glasses of water, and three or four liters of American wheat beer. I had a glass of water and one liter of beer, and I went to the bathroom twice. Kent never left the table. When I asked Kent about his superhuman bladder capacity, he thought it was due to years of working as a programmer glued to his computer and to the wonderful, easy-drinking wheat beer. This recipe is named in honor of Kent’s amazing bladder capacity. This recipe has a touch more hop character than many bottled, commercial examples on the market, but a lot less than some examples you might find. If you want less hop character, feel free to drop the late hop additions. If you really love hops and want to make a beer with lots of hop flavor and aroma, increase the late hop amounts as you see fit. However, going past the amounts listed below might knock it out of consideration in many competitions for being “too hoppy for style,” no matter how well it is brewed.

Ferment at 65° F (18° C). When finished, carbonate the beer to approximately 2.5 volumes. All-Grain Option Replace the wheat extract with 6 lbs. (2.72kg) American two-row malt and 6 lbs. (2.72kg) wheat malt. Mash at 152° F (67° C). Rye Option This beer can also be made with a portion of malted rye. The rye gives the beer a slightly spicy note and adds a certain creamy mouthfeel. Replace the wheat extract with 6 lbs. (2.72kg) American two-row malt, 3.75 lbs. (1.70kg) rye malt, and 3 lbs. (1.36kg) wheat malt. Mash at 152° F (67° C).

The degree to which a person experiences feelings of shame depends on two variables: the way other people are treating him (with admiration and respect, or with contempt and disdain), and the degree to which he himself already feels proud or ashamed. The more a person is shamed by others, from childhood by parents or peers who ridicule or reject him, the more he is likely to feel chronically shamed, and hypersensitive to feelings and experiences of being shamed, sometimes to the point of feeling that others are treating him with contempt or disdain even when they are not. For such people, and they are the rule among the violent, even a minor sign of real or imagined disrespect can trigger a homicidal reaction. The purpose of violence is to force respect from other people. The less self-respect people feel, the more they are dependent on respect from others; for without a certain minimal amount of respect, from others or the self, the self begins to feel dead inside, numb and empty. That is how the most violent criminals told me they felt, and it is clear that it is the most intolerable of all feelings (though it is actually an absence of feeling, lack of the feeling of pride, or self-love). When people lack self-respect, and feel they are incapable of eliciting respect from others in the form of admiration for their achievements or their personalities, they may see no way to get respect except in the form of fear, which I think of as a kind of ersatz substitute for admiration; and violence does elicit fear, as it is intended to. For example, I have spoken to many violent criminals who spoke of how gratifying it was to see fear in the eyes of their victims. Feelings of shame and self-contempt are often overlooked by others, because the people who experience them do their best to conceal such feelings behind a defensive mask of bravado and boasting. There is nothing more shameful than to feel ashamed — it reveals that a person has something to feel ashamed about. Why are these feelings of shame and self-contempt so bottomless, chronic, and almost ineradicable in the most violent men? Because, in the men I knew, they had been subjected to a degree of child abuse that was off the scale of anything I had previously thought of describing with that term. Many had been beaten nearly to death, raped repeatedly or prostituted, or neglected to a life-threatening degree by parents too disabled themselves to care for their child. And of those who had not experienced those extremes of physical abuse and neglect, my colleagues and I found that they had experienced a degree of emotional abuse that had been just as damaging: being focused on as the parents' emotional "whipping boy," in which they served as the scapegoat for whatever feelings of shame and humiliation their parents had suffered and then attempted to rid themselves of by transferring them onto their child, by subjecting him to systematic and chronic shaming and humiliation, taunting and ridicule.

Many of the patterns of nature we can discover only after they have been constructed by our mind. The systematic construction of such new patterns is the business of mathematics. The role which geometry plays in this respect with regard to some visual patterns is merely the most familiar instance of this. The great strength of mathematics is that it enables us to describe abstract patterns which cannot be perceived by our senses, and to state the common properties of hierarchies or classes of patterns of a highly abstract character. Every algebraic equation or set of such equations defines in this sense a class of patterns, with the individual manifestation of this kind of pattern being particularized as we substitute definite values for the variables.

regression as dummy variables Explain the importance of the error term plot Identify assumptions of regression, and know how to test and correct assumption violations Multiple regression is one of the most widely used multivariate statistical techniques for analyzing three or more variables. This chapter uses multiple regression to examine such relationships, and thereby extends the discussion in Chapter 14. The popularity of multiple regression is due largely to the ease with which it takes control variables (or rival hypotheses) into account. In Chapter 10, we discussed briefly how contingency tables can be used for this purpose, but doing so is often a cumbersome and sometimes inconclusive effort. By contrast, multiple regression easily incorporates multiple independent variables. Another reason for its popularity is that it also takes into account nominal independent variables. However, multiple regression is no substitute for bivariate analysis. Indeed, managers or analysts with an interest in a specific bivariate relationship will conduct a bivariate analysis first, before examining whether the relationship is robust in the presence of numerous control variables. And before conducting bivariate analysis, analysts need to conduct univariate analysis to better understand their variables. Thus, multiple regression is usually one of the last steps of analysis. Indeed, multiple regression is often used to test the robustness of bivariate relationships when control variables are taken into account. The flexibility with which multiple regression takes control variables into account comes at a price, though. Regression, like the t-test, is based on numerous assumptions. Regression results cannot be assumed to be robust in the face of assumption violations. Testing of assumptions is always part of multiple regression analysis. Multiple regression is carried out in the following sequence: (1) model specification (that is, identification of dependent and independent variables), (2) testing of regression assumptions, (3) correction of assumption violations, if any, and (4) reporting of the results of the final regression model. This chapter examines these four steps and discusses essential concepts related to simple and multiple regression. Chapters 16 and 17 extend this discussion by examining the use of logistic regression and time series analysis. MODEL SPECIFICATION Multiple regression is an extension of simple regression, but an important difference exists between the two methods: multiple regression aims for full model specification. This means that analysts seek to account for all of the variables that affect the dependent variable; by contrast, simple regression examines the effect of only one independent variable. Philosophically, the phrase identifying the key difference—“all of the variables that affect the dependent variable”—is divided into two parts. The first part involves identifying the variables that are of most (theoretical and practical) relevance in explaining the dependent

The lawyer’s stakes at the table turned out to be not even colonial notes of the usual baffling variability, but certificates drawable upon a tobacco warehouse in Virginia, and Smith presented one without much hope, the first time he tried their use as payment. But it was accepted without demur, at fifty-five per centum of face, New-York’s merchants seeming all to maintain within themselves a register of values for every conceivable money-substitute they might encounter. Wampum, tobacco bales, rum by the gallon: it was all money, in a world without money. Between the tobacco tickets and his own pointedly-returned guineas, Smith calculated he now possessed enough to reach Christmas in relative ease – if he could avoid being knocked on the head for spoiling De Lancey’s game against the Governor, or offending in some other role pressed upon him, or falling victim to a misadventure entirely unsuspected.
