However haldol 1.5 mg with visa treatment borderline personality disorder, in correlational research buy haldol 1.5mg overnight delivery treatment quadricep strain, we do not always know which factor occurred first. For example, if we simply measure the coffee drink- ing and nervousness of some people after the fact, it may be that participants who were already more nervous then tended to drink more coffee. Therefore, maybe greater nerv- ousness actually caused greater coffee consumption. But, in correlational research, we do little to control or eliminate other potentially causal variables. For exam- ple, in the coffee study, some participants may have had less sleep than others the night before testing. Perhaps the lack of sleep caused those people to be more nervous and to drink more coffee. In experiments we apply the in- dependent variable first, and we control other potential causal variables, so experiments provide better evidence for identifying the causes of a behavior. Unfortunately, this issue is often lost in the popular media, so be skeptical the next time some one uses correlation and cause together. The problem is that people often ignore that a relationship may be a meaningless coincidence. For example, here’s a re- lationship: As the number of toilets in a neighborhood increases, the number of crimes committed in that neighborhood also increases. Crime tends to occur more frequently in the crowded neighborhoods of large cities. Here’s a serious example: A particular neurological disease occurs more often in the colder, northern areas of the United States than in the warmer, southern areas. But, for all the reasons given above, the mere ex- istence of this relationship is not evidence of causality. The north also has fewer sunny days, burns more heating oil, and differs from the south in many other ways. One of these variables might be the cause, while coincidentally, colder temperatures are also present. Instead, correlational research is used to simply describe how nature relates the variables, without identifying the cause. Distinguishing Characteristics of Correlational Analysis There are four major differences between how we handle data in a correlational analy- sis versus in an experiment. First, back in our coffee experiment, we would examine the mean nervousness score (Y) for each condition of the amount of coffee consumed (X). With correlational data, however, we typically have a large range of different X scores: People would probably report many amounts of coffee beyond only 1, 2, or 3 cups. Therefore, in correlational procedures, we do not compute a mean Y score at each X. A second difference is that, because we examine all pairs of X–Y scores, correla- tional procedures involve one sample: In correlational designs, N always stands for the number of pairs of scores in the data. Third, we will not use the terms independent and dependent variable with a correla- tional study (although some researchers argue that these terms are acceptable here). Conversely, if we ask, “For a given nervousness score, what is the amount of coffee consumed? Further, recall that, in a relationship, particular Y scores naturally occur at a particular X. The procedures for doing this are described in the next chapter, where the X variable is called the predictor variable, and the Y variable is called the criterion variable. As you’ll see, researchers used correlational techniques to identify X variables that are “good predictors” of Y scores. Finally, as in the next section, we graph correlational data by creating a scatterplot. Plotting Correlational Data: The Scatterplot A scatterplot is a graph that shows the location of each data point formed by a pair of X–Y scores. It shows that people drinking 1 cup have nervousness scores around 1 or 2, but those drinking 2 cups have higher nervousness scores around 2 or 3, and so on. Thus, we see that one batch of data points (and Y scores) tend to occur with one X, and a different batch of data points (and thus different Y scores) are at a different X. Real research typically involves a larger N and the data points will not form such a clear pattern. A data point that is relatively far from the majority of data points in the scatterplot is referred to as an outlier—it lies out of the general pattern. When you conduct a correlational study, always begin the analysis by creating a scat- terplot. The scatterplot allows you to see the relationship that is present and to map out the best way to summarize it. Instead, from the description provided, you should envision the scatterplot, and then you will understand the relationship formed by the data.
He considers that this starting-point will also be the origin of rational activity (noÓv and boÅleusiv) discount haldol 1.5mg amex medications 1040, and having disposed of ‘chance’ (tÅch) as an evidently unsatisfactory candidate for this function he argues that the starting-point wanted is in fact the starting-point of movement in the soul; then it is clear that this starting-point is God order 1.5 mg haldol with mastercard symptoms wisdom teeth. Thus God is the starting-point of all psychic activity, both of reasoning (no¦sai) and of the irrational impulses (¾rma©) on which eutuchia is based. God is even more powerful than the divine principle in man, the intellect (noÓv), and it is for this reason that people who are devoid of rational activity, too, can make the right choice: they succeed without reasoning because they still have God, although the wise people also have God and use his movement in their calculation of the future, either by experience or by habit: thus there is a more rational form of divination as well. Both irrational and rational divination, then, ‘use’ God (who sees the future as well as the present), but God moves more strongly in those people whose reasoning faculty is disengaged. Thus God’s movement is present both in the irrational people daimonia because it is beyond human control, as is indicated by the use of the word daim»niov in Somn. The individual human nature is further called daimonia because it works more strongly when reason is inactive, and because it plays the part of intermediary between God and man, which Greek tradition assigned to demons. This is an obvious reference to the distribution argument in 1247 a 28–9, where it was stated that it is ‘paradoxical’ that a god or demon should love simple people, not the best and wisest (m t¼n bltiston kaª fronimÛtaton); evidently Aristotle remains aware of the distribution argument and anticipates it by means of a careful presentation of his own explanation. For the purpose of clarity I will print ﬁrst a text and a translation of each section and then add comments on the section in question. The text of the manuscript tradition will be followed as closely as possible; any deviations from it will be accounted for from line to line. It seems to me that the numerousproblemsofinterpretationinthischapteraredueatleastasmuchtoAristotle’sconciseand often frankly clumsy way of writing as to possible corruptions in the text. Therefore the interpreter should maintain a fundamental distinction between hypotheses concerning the original text which Aristotle wrote down, and hypotheses concerning what he intended to say. This distinction seems to have often been ignored, and apparently interpreters have, with an appeal to the abysmal state of the text, proposed many conjectures with a view to making the text comply with interpretations mainly prompted by theological assertions in other Aristotelian writings. The unfortunate consequence of this process is that there is no generally accepted text on which to base a debate concerning the tenability of a particular interpretation: in order to scrutinise it, one has to be willing to accept, for the sake of argument, the readings proposed by the interpreter, while these readings were actually chosen to support the interpretation. This account should be based principally on the immediate context and only secondarily on statements on the subject in other Aristotelian writings. Aristotle on divine movement and human nature 249 23 panta staiá £35 sti tiv rc ¨v oÉk stin llh xw, aÌth 24 d di t¼ toiaÅth e²nai toioÓto dÅnatai poie±n;36 t¼ d 25 zhtoÅmenon toÓtì sti, t©v ¡ t¦v kinsewv rc n t¦ yuc¦; d¦lon 26 d ãsper n tä Âlw qe¼v kn ke©nw. For we did not deliberate at a particular moment concerning a particular thing after having deliberated – no, there is a certain starting-point, nor did we think after having already thought before thinking, and so on to inﬁnity. Intelligence, therefore, is not the starting-point of thinking nor is counsel the starting-point of de- liberation. Or is there some starting-point beyond which there is no other, and is this starting-point such as to be able to produce such an effect? What we are looking for is this: what is the starting-point of the movement in the soul? It is now evident that, as it is a god that moves the universe, so it is in the soul. It is of vital importance to notice that the ‘starting-point’ (rc) Aristotle is seeking is the starting-point of all movement in the soul, both of ‘thinking’ (no¦sai) and of ‘desiring’ (piqum¦sai, ¾rma©). Thus God is also the ‘principle of movement’ in the souls of those people who actualise ‘intellect and deliberation’ (noÓv, boÅleusiv). Verdenius (private correspondence) suggested to me as a translation of the whole sentence: ‘It is clear that this starting- point is analogous to the part which God plays in the universe, where he moves everything’ (reading kaª pn ke©nw and taking ka© as specifying ãsper n tä Âlw). However, the connection with the following then becomes difﬁcult, for the rc sought is not t¼ n ¡m±n qe±on (which is the noÓv) but ¾ qe»v (who is kre±tton toÓ noÓ). The analogy which Aristotle wants to express is best achieved when we read kn ke©nw, where ke©nw refers to yuc (as so often in this chapter a neuter pronoun refers to a masculine or feminine noun; for this reason Wood’s conjecture kn ke©nh can be left aside). Dirlmeier reads kaª pn ke±no and translates: ‘so bewegt er auch alles jene (in der Seele)’, but this is awkward as Greek. Aristotle anticipates this idea by arguing that, admittedly, this is true in a certain way (pwv), but the intellect itself has got its movement from something which is ‘superior’ (kre±tton,cf. Wagner (1970) 105–8, who wrongly follows Dirlmeier (1962a) 108 in concluding that ‘this divine element moves the processes in the soul’ (‘dieses qe±on bewegt die Vorgange in der Seele’), which is incompatible with Wagner’s¨ own conclusion that t¼ n ¡m±n qe±on is equivalent to ¾ noÓv which is distinguished from ¾ qe»v:if Wagner reads qeä in 1248a 38, how can he conclude that not ¾ qe»v but t¼ qe±on is the rc t¦v kinsewv n t¦ yuc¦? Woods (1982, 182) and Dirlmeier (1962a, 490) refer to 1246 b 10–12: ll mn oÉdì retá cr¦tai gr aÉt¦á ¡ gr toÓ rcontov ret t¦ toÓ rcomnou cr¦tai (on which see Moraux (1971) 264–5). Aristotle on divine movement and human nature 251 1248 a 29–34: 29 kaª di toÓto, 30 Á43 o¬ plai legon, eÉtuce±v kaloÓntai o° n ¾rmswsi 31 katorqoÓsin44 logoi Àntev, kaª bouleÅesqai oÉ sumfrei aÉto±v. For they have such a starting-point which is stronger than intelligence and deliberation (others have reasoning; this the lucky people do not possess) and they have divine inspiration,48 but they are not capable of intelligence and deliberation: they hit the mark without reasoning. The adjunct ‘though lacking reasoning’ (logoi Àntev) again stresses what has already been noted in the beginning of the chapter (1247 a 4; 13), that their success is not due to reason or intelligence; the sentence ‘it is not proﬁtable for them to deliberate’ refers to 1247 b 29–37, where Aristotle says that in the case of eutuchia the natural impulse (¾rm) is contrary to reasoning and that reasoning is idle (¾d logism¼v §n l©qiov, 35). The anticipation in lines 26–9 now turns out to be very appropriate: having discussed the part played by the intellect (noÓv being on a par in this context with l»gov and boÅleusiv) in human action, Aristotle stipulates that there is a starting-point which is even more powerful than this, and that this starting-point is the cause of the lucky people’s success. But it is improbable that these o° d should be the subject of cousi (‘they have’) and that toÓto (‘this’) should refer to rc, since it is hardly credible that these people do not have this starting-point (rc), for this starting-point was said to be the origin of all movement in the soul, including intellect, reason and deliberation. Various solutions to this problem might be suggested: (1) The subject of cousi (‘they have’) is not o° d, but the ‘irrational people’ (the logoi); and toÓto (‘this’) refers to l»gov (‘reason’). It might be objected to this possible solution that the sentence toÓto dì oÉ dÅnatai (‘they are not capable. But this objection can be countered in two ways: either (i) the sentence o° d t¼n l»goná toÓto dì oÉk cousi (‘others have reasoning; this the lucky people do not possess’) can be taken as a parenthesis (as does Susemihl, who puts it between brackets): in this case the redun- dancy is not unacceptable; or (ii) there is a new change of subject: the second toÓto (‘this’) refers to nqousiasm»n (‘divine inspiration’) and the subject of dÅnantai (‘they are capable’) is o° d, the people with reason (l»gov).
The underlying abnor- mality is loss of the intramural neurons that control the inhibitory neurotransmitters cheap 5 mg haldol amex symptoms yeast infection men. Other diseases that can cause secondary achalasia through destruction of these neurons include Chagas’ disease discount 10 mg haldol with mastercard treatment magazine, malignancy, and viral infections. Typical clinical symptoms of achalasia include dysphagia with both solids and liquids equally and worsening of symp- toms with emotional stressors and rapid eating. The presence of esophageal reﬂux symptoms is inconsistent with the diagnosis of achalasia. The course is usually progressive, with weight loss occurring over several months. Nitrates and calcium channel blockers offer short-term beneﬁts for relief of symp- toms but lose efﬁcacy over time. Endoscopic injections of botulinum toxin are also effective for short periods but may lead to ﬁbrosis with repeated injections. Balloon dila- tation is effective in approximately 85% of patients with the side effect of perforation or bleeding. Finally, some patients ultimately require surgical intervention with myotomy, which has equal success compared to balloon dilatation. Ery- thema nodosum and venous thromboembolism also generally correlate with intestinal disease activity. The progressive and gradual nature of the process is evident in worsen- ing tolerance for solid foods over the course of months. The patient’s prior partial gastrectomy predisposes him to gastric outlet obstruction as a result of stricture at the previous anastomosis. Although the patient has no current symptoms of peptic ulcer disease, underlying malignancy with gastric outlet obstruction must be considered as gastric ulcers may de- velop into cancerous lesions if left untreated. Other factors that support the diagnosis of gastric outlet obstruction are the abdominal x-ray ﬁndings of dilated gastric bubble and the lack of air in the small bowel. Small bowel obstruction presents acutely with abdomi- nal distention, pain, and vomiting. Gastroparesis is common in poorly controlled diabetic patients, symptomatically affecting approximately 10% of those patients. Finally, cholelithiasis is most often asymptomatic but can present as biliary colic. There should be associated pain in the right upper quad- rant and epigastrium with eating. Again, the abdominal radiogram is normal in this con- dition with the possible exception of stones seen within the gallbladder. Gastric adenocarcinoma remains a prevalent malig- nancy worldwide despite signiﬁcant decline in incidence over the last 50 years. A major pathophysiologic risk appears to be related to bacterial conversion of ingested nitrites into carcinogens in the stomach. Risk factors for the development of gastric cancer include long-term ingestion of foods with high concentrations of nitrite (dried, smoked, salted foods) and conditions that promote bacterial colonization/infection in the stomach, such as Helicobacter infection, chronic gastritis, and achlorhydria. The disorder is notable for both endocrine and exo- crine dysfunction of the pancreas. Often diabetes ensues as a result of loss of islet cell function; though insulin-dependent, it is generally not as prone to diabetic ketoacidosis or coma as are other forms of diabetes mellitus. As pancreatic enzymes are essential to fat digestion, their absence leads to fat malabsorption and steatorrhea. Replacement of pancre- atic enzymes orally with meals will correct the vitamin deﬁciencies and steatorrhea. The incidence of pancreatic adenocarcinoma is increased in patients with chronic pancreati- tis, with a 20-year cumulative incidence of 4%. Chronic abdominal pain is nearly ubiqui- tous in this disorder, and narcotic dependence is common. Niacin is a water-soluble vitamin, and absorption is not affected by pancreatic exocrine dysfunction. Fat malabsorption syndromes classically lead to weight loss and many vitamin deﬁciencies, including iron, vitamin B12, vitamin D, and vitamin K. Pancreatic insufﬁciency must be considered in cases of malabsorption, but destruction of the organ must be near total for this to occur, usually in the setting of long-standing alcohol abuse. Celiac disease affects 1% of Americans, often presents with symptoms similar to those of irritable bowel syndrome, and requires an endoscopy with biopsy to conﬁrm the diagnosis. Other causes of steatorrhea include bacterial overgrowth, bariatric surgery, liver disease, and Whipple’s disease. A 24-h stool collection is a formal way to conﬁrm steatorrhea, though a consistent patient history may be adequate to begin evaluation. Small-intestinal disease typically will result in fecal fat of ~15–25 g/day, and pancreatic exocrine insufﬁciency may result in >30 g/day. Chronic pancreatitis can develop in individuals who consume as little as 50 g of alcohol daily (equivalent to ~30–40 ounces of beer).
