In amblyopia ex anopsia, the visual acuity of one eye is decreased without presence of organic eye disease, usually because of strabismus or anisometropia in childhood. Intermediate Vision Visual Acuity Standards: As listed below or better; Each eye separately; Snellen equivalent; and With or without correction. First or Second Class Third Class Near Vision Measured at 16 inches 20/40 20/40 Intermediate Vision Measured at 32 inches; Age 50 and over only 20/40 No requirement I. If age 50 or older, near vision of 20/40 or better, Snellen equivalent, at both 16 inches and 32 inches in each eye separately, with or without corrective lenses. Equipment and Examination Techniques Note: If correction is required to meet standards, only corrected visual acuity needs to be tested and recorded. For testing near at 16 inches and intermediate at 32 inches, acceptable substitutes: any commercially available visual acuities and heterophoria testing devices. For testing of intermediate vision, some equipment may require additional apparatus. Near visual acuity and intermediate visual acuity, if the latter is required, are determined for each eye separately and for both eyes together. If the applicant needs glasses to meet visual acuity standards, the findings are recorded, and the certificate appropriately limited. If an applicant has no lenses that bring intermediate and/or near visual acuity to the required standards, or better, in each eye, no certificate may be issued, and the applicant is referred to an eye specialist for appropriate visual evaluation and correction. The examination is conducted in a well-lighted room with the source of light behind the applicant. The applicant holds the chart 16 inches (near) and 32 inches (intermediate) from the eyes in a position that will provide uniform illumination. To ensure that the chart is held at exactly 16 inches or 32 inches from the eyes, a string of that length may be attached to the chart. Guide for Aviation Medical Examiners i. The smallest type correctly read with each eye separately and both eyes together is recorded in linear value. Letter types and charts are reproduced from aeronautical charts in their actual size. Aerospace Medical Disposition When correcting glasses are required to meet the near and intermediate vision standards, an appropriate limitation will be placed on the medical certificate. Contact lenses that correct only for near or intermediate visual acuity are not considered acceptable for aviation duties. If the applicant meets the uncorrected near or intermediate vision standard of 20/40, but already uses spectacles that correct the vision better than 20/40, it is recommended that the Examiner enter the limitation for near or intermediate vision corrective glasses on the certificate.

In addition muscle relaxant herniated disc buy discount rumalaya gel on-line, significantly less citrateanticoagulated filters were terminated for clotting (16 muscle relaxant withdrawal purchase cheapest rumalaya gel. Three patients in the citrate group had metabolic alkalosis and two had hypocalcemia muscle relaxant with ibuprofen purchase rumalaya gel 30 gr without prescription. However, the number of major bleedings and the need for transfusion was significantly greater in the heparin group. Two cases of metabolic alkalosis were noted in the heparin group and two episodes of hypocalcemia in the citrate group. Both treatment arms had a relatively short filter life (13 hours for regional heparinization and 17 hours for citrate) that did not differ significantly. Nadroparin was started with a bolus of 2850 U followed by 380 U/h without further monitoring. Citrate (500 mmol/l) was administered at a dose of 3 mmol per liter blood flow, without monitoring of postfilter ionized calcium. The primary outcomes were safety, defined as the absence of adverse events necessitating discontinuation of the study anticoagulant, and efficacy, defined as circuit survival. Safety was significantly better in the citrate group with only two patients requiring a change in anticoagulation regimen vs. A computerdriven combination of buffered and nonbuffered replacement fluids was used in the citrate group, explaining why metabolic alkalosis occurred more frequently in the nadroparin group. Rather surprisingly, the authors also found an improved renal recovery and an improved hospital survival in the citrate group. This could not be attributed to differences in severity of illness, nor in bleeding or transfusion requirement, and requires further investigation. In observational trials, the most frequent metabolic complication is metabolic alkalosis, occurring in up to 50% of the patients. Markedly reduced citrate clearances and lower ionized calcium levels have been found in patients with acute liver failure or with severe liver cirrhosis. The ratio of total to ionized calcium appears to be the best parameter to detect citrate accumulation611,612 with an optimal cutoff at 2. There was no difference in filter survival (with electively discontinued filters being censored). Three patients in each group had bleeding, with no difference in transfusion requirement between the two groups. The incidence of bleeding was low and not different between the two anticoagulants. A possible exception can be made for patients who do not have contraindications for citrate. Randomized trials comparing citrate with heparins have been performed in patients without increased bleeding risk. It is cumbersome and difficult to titrate because heparin has a much longer half-life than protamine, inducing a risk of rebound. Its main clinical complication is the development of thrombocytopenia with or without thrombosis. Candidates are the direct thrombin inhibitors lepirudin, argatroban, or bivaluridin, or the antithrombin-dependent Factor Xa inhibitors, danaparoid or fondaparinix. The second aspect of the citrate protocol provides prevention of citrate-induced systemic hypocalcemia by providing a calcium chloride continuous infusion (8 g calcium chloride per liter normal saline) to the patient via a central line. Calcium is a requisite cofactor in both the intrinsic and extrinsic coagulation cascades. Citrate functions by binding free calcium, thereby inhibiting coagulation in both the intrinsic and extrinsic coagulation pathways. Most studies on indwelling tunneled dialysis catheters have been performed in chronic dialysis patients. No recommendation can be given regarding the optimal timing to change the nontunneled-uncuffed catheter to a more permanent access. It seems reasonable to create a more permanent access when recovery of kidney function is unlikely. The optimal timing should take into account the increased risk of infection with untunneled catheters, but also the practical issues related to the insertion of a tunneled catheter. Several configurations of dialysis catheter lumen and tip have emerged over the years with no proven advantage of one design over another. The outer diameter varies between 11 and 14 French and it is self-evident that larger sizes decrease the risk of inadequate blood flow. In order to provide an adequate blood flow and reduce the risk of recirculation, the tip of the catheter should be in a large vein (see Recommendation 5. Further modifications, including the use of swan-neck catheters, T-fluted catheters, curled intraperitoneal portions, dual cuffs, and insertion through the rectus muscle instead of the midline, have been made to reduce remaining complications such as peritonitis, exit/tunnel infection, cuff extrusion, obstruction, and dialysate leaks. In the remaining 30 patients, those with tunneled catheters had an increased insertion time and more femoral hematomas, but also less dysfunction, fewer infectious and thrombotic complications, and a significantly better catheter survival. In addition, the use of tunneled catheters for starting acute dialysis is not widespread practice. Catheters in the right internal jugular vein have a straight course into the right brachiocephalic vein and superior vena cava, and, therefore, the least contact with the vessel wall. A catheter inserted through the subclavian or the left jugular vein has one or more angulations. Whether this recommendation should be extended to the left jugular vein remains unclear. In patients where the subclavian vein remains the only available option, preference should be given to the dominant side in order to spare the nondominant side for eventual future permanent access. Because the subclavian vein should be avoided, the remaining options are the jugular and femoral veins. The use of femoral catheters is thought to be associated with the highest risk of infection, and avoidance of femoral lines is part of many ``central line bundles' that intend to reduce the incidence of catheter-related bloodstream infection. Ultrasound was seldom used, probably explaining the somewhat higher rate of failure on one side and crossover in the jugular group.

This bacterium is one of the most infectious microorganisms known and poses a substantial threat as a potential biological weapon. This classification is reserved for those pathogens deemed to pose the highest risk for intentional misuse. The nonspecific disease presentation of tularemia, the high morbidity, the significant mortality if untreated, and the limited ability to obtain a rapid diagnosis are other characteristics that contribute to the effectiveness of F tularensis as a potential biological weapon. Although tularemia responds to antibiotic therapy, the intentional use of a genetically modified antibiotic-resistant strain could make these countermeasures ineffective. McCoy and Chapin successfully cultured the causative agent and named it Bacterium tularense. He described the clinical syndromes associated with Francisella infection and named it "tularemia. However, as mounting scientific data supported the creation of a new genus for this remarkable pathogen, this bacterium was assigned to its own genus and the name Francisella was proposed in tribute to Edward Francis. F tularensis is considered to have four subspecies: (1) tularensis, (2) holarctica, (3) mediasiatica, and (4) novicida. F tularensis subspecies holarctica typically causes a less clinically severe disease than subspecies tularensis, but has been documented to cause bacteremia in immunocompetent individuals. Photograph: Courtesy of Dr Larry Stauffer, Oregon State Public Health Laboratories, Centers for Disease Control and Prevention, Atlanta, Georgia, Public Health Image Library, Image 1904. Tularemia been isolated in the central Asian republics of the former Soviet Union, and it appears to be substantially less virulent in a rabbit model compared to F tularensis subspecies tularensis. F tularensis subspecies novicida, also referred to as F novicida, is believed to be avirulent in healthy humans. Reported cases associated with this subspecies usually involve patients with other underlying health conditions. Another closely related species, Francisella philomiragia, has also been described as a human pathogen. Healthcare providers need to understand the range of possible presentations of tularemia to use diagnostic testing and antibiotic therapy appropriately for these infections. Most cases of naturally occurring tularemia are ulceroglandular disease, involving an ulcer at the inoculation site and regional lymphadenopathy. Variations of ulceroglandular disease associated with different inoculation sites include ocular (oculoglandular) and oropharyngeal disease. Occasionally patients with tularemia present with a nonspecific febrile systemic illness (typhoidal tularemia) without evidence of a primary inoculation site. Pulmonary disease from F tularensis can occur naturally (pneumonic tularemia), but is uncommon and should raise suspicion of a biological attack, particularly if the cause is not readily discernable and significant numbers of cases are diagnosed. Because of the threat of this microorganism as a biological weapon, clusters of cases in a population or geographic area not accustomed to tularemia outbreaks should trigger consideration for further investigation. An investigation should yield the likely cause of the outbreak, which could be varied (exposure to infected animals, arthropod borne, etc). By determining the source of the outbreak, it may be possible to implement control measures, such as water treatment or use of an alternative water supply if the outbreak is traced to a waterborne source. Epidemiology F tularensis subspecies tularensis (type A) is the most virulent subspecies and found predominantly in North America. This subspecies has recently been genetically subdivided into two subpopulations, A. The subpopulations are distinct in mortality rates, geographic distribution, transmission vectors, and hosts. In the United States, 90 to 154 cases of tularemia have been reported yearly from 2001 to 2010, according to the Centers for Disease Control and Prevention.

As a result muscle relaxant amazon rumalaya gel 30gr sale, the researchers predicted that ice cream consumption would be highest among dieters who sat close to spasms back muscles buy rumalaya gel 30 gr low price muscle relaxant quiz buy generic rumalaya gel 30gr line the snacks and were allowed to eat them. Dieters ate significantly more when they were highly tempted by sitting next to the M&M candies and were told the candies were available to be eaten. Notably, however, dieters ate the least when they were seated far from the chocolates and were told they could indulge in them (which, being dieters, they did not). This pattern may represent an inoculation effect, which would be an intriguing idea for future depletion research. A second study replicated the loss of self-control among dieters after having engaged in emotion regulation (Vohs & Heatherton, 2000). In this experiment, dieters watched a sad movie about a woman on her deathbed saying good-bye to her husband, two sons, and mother. Participants were asked either to suppress their emotions or to watch the movie naturally. As expected, asking these women to engage in emotion regulation, as opposed to being able to watch the same movie but without having to suppress sad feelings, led them to eat more ice cream later. Both groups reported similarly negative feelings after the movie, meaning that differences in mood did not account for eating differences, but having to stifle those feelings led to a depletion of the resource that later would have helped them control their ice cream consumption. A third study showed that persistence drops after dieters have had to overcome the temptation of forbidden foods. In this study, being highly tempted by an array of snack foods led subsequent persistence on an embedded-figures task to be impaired, relative to persistence among dieters who watch the same boring fi lm and looked at the same snack foods but who did so from across the room. Thus, regulating the consumption of food determines and is determined by the availability of self-regulatory resources-but only among people for whom caloric regimens were highly important and thus demanded much regulation. If one includes the paid consumption of energy and utilities such as water, the typical modern citizen spends money every day. Much spending is fairly inevitable, and other spending is appropriate and judicious. Still, some money is spent impulsively and in ways that the consumer may later regret. Vohs and Faber (2005) turned to the self-regulatory resource model to help explain why people spend money impulsively. Impulsive buying is defined purchases that result from an urge that arises spontaneously within the consumer to buy. In impulsive purchasing, the desire to purchase is unreflective (Strack, Werth, & Deutsch, in press) and not based on any careful considerations of why the product should be acquired (Rook & Fisher 1995). Two studies manipulated attentional control demands as a way to alter self-regulatory ability. Participants watched an audioless video of a woman being interviewed that, at the same time, showed irrelevant words appearing at the bottom of the screen every 30 seconds. Some participants were not told anything about the irrelevant words, whereas those in the depletion condition were told not to look at the words and if they found themselves orienting toward the words to revert their eyes back to the interviewee. In one study, participants were then given a scale to measure immediate buying impulses; in another study, participants were shown high-end products. Both studies showed an effect of self-regulatory resource availability on impulsive spending tendencies: participants who had earlier used their resources to orient their attention away from a distracting stimulus later reported stronger urges to spend impulsively (Study 1) and gave higher willingnessto-pay rates (Study 2), as compared to participants who did not engage in attention control. Feeling a spontaneous urge to buy is, as we saw earlier, the root of impulsive spending, and one way to control that urge is to believe a product is not worth its monetary price (Rook & Fisher, 1995). That self-regulatory resource depletion affected impulsive spending tendencies both at the level of the impulse and the cognitive strategies to rein in that impulse is noteworthy. Moreover, this research found that actual impulsive spending was affected by resource availability. One of these studies asked participants in the resource depletion condition to suppress thoughts of a white bear; the other study asked participants to read aloud a boring text with emotion. Subsequently, participants were given the opportunity to buy in a spontaneous, ad hoc purchasing situation in a mock store. As predicted, participants whose resources had been depleted spent more impulsive than did participants who had not expended their resources. This effect was found in terms of purchases of bookstore-like products, such as school insignia pens, coffee mugs, and decks of playing cards (Study 3) as well as grocery store items, such as cookies, pretzels, and potato chips (Study 4). Moreover, the latter two studies incorporated the idea of underlying tendencies toward a certain type of self-control failure, in a similar manner as was done in the work on chronic dieters (Vohs & Heatherton, 2000). In this work, however, generalized tendencies to want to spend money impulsively were measured prior to the experimental manipulation of self-regulatory demands. Similar to the findings on dieters, Vohs and Faber (2005) also found that the effect of self-regulatory resource depletion was exacerbated among people who normally feel strong desires to buy impulsively. In contrast to the work on dieters versus nondieters, however, was the fact that even participants who were low in general impulsive spending tendencies showed heightened purchasing behavior when depleted. Hence, spontaneous urges to buy something too are affected by self-regulatory resources (Vohs & Faber, 2005). Theoretically, the strength of the urge and inhibitions on that urge have been considered to be orthogonal, but to detect a change in the potency of the impulse with depletion suggests that empirically the two core components of self-control may be intricately related. Thus far we have discussed about impulsive consumption in the context of purchasing. Impulses may also affect what people consume in another fashion, namely watching movies. The core idea behind this research (Novemsky & Baumeister, 2005) was that, at times, choosing a more virtuous option may require overriding an impulse to do something nonvirtuous, and so self-regulation is required for choosing the path of virtue. In one study, Novemsky and Baumeister (2005) offered students a choice of a movie to watch (for later, not immediate viewing). These options were presented either before or after an intensive study session, which was assumed to be somewhat depleting. Different levels of depletion were inferred based on study time in the library. Sure enough, when students were fresh and their resources were not depleted from studying, they exhibited a marked preference for the highbrow fi lms. The implication is that some consumer decisions present a challenge between higher and lower impulses. Self-regulation enables human beings to override the latter sort of impulse in order to pursue the former. But when self-regulatory resources have been depleted, preferences shift toward the less virtuous product. Making Intelligent Decisions the ability to make the right decision should (by definition) free consumers from a great deal of regret. However, because the "right" option is not always readily apparent when one faces a decision, the human psyche has developed highly intelligent methods for determining the best answer, such as cost-benefit analyses. The agentic self must oversee the active parts of the decision making process, such as problem solving, but it is not involved in automatic information processing actions such as categorization. Indeed, one review of the problem solving literature (Crinella & Yu, 2000) concluded that almost all problem solving requires executive functioning.

Low thyroid stimulating hormone levels in older people (>60 years) should trigger a small dose reduction of 25 g daily muscle relaxant trade names purchase rumalaya gel 30 gr with amex, or on alternate days ql spasms rumalaya gel 30gr online. A persistently abnormal thyroid stimulating hormone level Patient non-compliance (non-concordance) with levothyroxine therapy can sometimes be a problem spasms in throat rumalaya gel 30 gr otc. When levothyroxine is taken only on the day of attendance for the blood test this typically results in a chronically raised thyroid stimulating hormone level but normal or raised free thyroxine levels. In many cases reiterating that levothyroxine has a long half life (box 3) is sufficient to persuade the patient to take the tablets regularly, even if they do not feel different on days when the dose is missed. In most people it is safe to recommend that they take a double dose on the day after a missed tablet (exceptions being active ischaemic heart disease and atrial fibrillation). A small randomised controlled crossover trial has shown that giving levothyroxine weekly (seven times the daily dose taken once a week) is a safe regimen26 and can be used in refractory cases. Less commonly a persistently raised thyroid stimulating hormone level despite an apparently adequate dose of levothyroxine can be caused by drugs (box 4) or by malabsorption. It is worth excluding coeliac disease (measuring endomyseal or transglutaminase antibodies) and autoimmune gastritis (measuring parietal cell antibodies) in this situation, as observational studies have shown that the two autoimmune conditions coexist with autoimmune hypothyroidism more often than would be expected. Patient does not feel well despite well controlled thyroid stimulating hormone level (0. At first I put it down to pressures at work, but after six months I was feeling quite miserable. I found that I was coming home from work and needed to take a nap before I could face an evening out. It was increasingly difficult even to walk the 100 m up hill to my house, needing to stop several times. However, it still took me a full nine months before I visited my doctor, who found out after a blood test that I had an underactive thyroid gland and prescribed me levothyroxine. The doctor was surprised that I was still managing to function as my results were so extreme. I remained well for the next 11 years, until I started to feel extremely tired again, and this time I was losing weight. I was diagnosed with type 1 diabetes and am beginning to feel better again on insulin.

In these instances, or in someone with active angina pectoris or recent acute coronary syndrome, the starting dose of levothyroxine should be 12. Hypothyroidism in pregnancy Maternal hypothyroidism in pregnancy is associated with adverse obstetric outcomes and long term developmental sequelae. The management of hypothyroidism in pregnancy has been discussed in detail in a recent review. A recent systemic review found insufficient evidence to recommend routine screening of thyroid disease in the general adult population. Several studies have examined whether combination therapy of primary hypothyroidism with triiodothyronine and levothyroxine might be helpful. A recent prospective study has, however, shown that normal triiodothyronine levels could be achieved with levothyroxine treatment alone in patients after total thyroidectomy, without the need to take triiodothyronine. It is substantially more expensive than levothyroxine and of no proved additional benefit. Unanswered questions Why do some patients with hypothyroidism continue to feel unwell despite taking adequate doses of levothyroxine Would a combination of levothyroxine with slow release formulation of triidothyronine have advantages over levothyroxine therapy alone Is the vascular risk associated with subclinical hypothyroidism ameliorated by early thyroid hormone replacement Are there differences in long term outcome from treating adults with hypothyroidism to different target ranges for serum thyroid stimulating hormone Referral should, however, be considered in hypothyroid patients whose symptoms do not respond or worsen after treatment with levothyroxine; the serum thyroid stimulating hormone level is persistently raised while taking the full dose of levothyroxine; or if other morbidity or complications exist (for example, active and unstable ischaemic heart disease).

These trials should be standardized for treatment dose muscle relaxant half-life buy rumalaya gel 30 gr with amex, buffer muscle relaxant hamstring discount 30 gr rumalaya gel amex, membrane spasms temporal area buy cheap rumalaya gel 30 gr on line, anticoagulant, and timing of treatment. Options for correction of metabolic acidosis include the use of acetate-, lactate-, and bicarbonatecontaining replacement solutions or dialysate. Some centers use citrate anticoagulation, and the citrate load provides an adequate supply of anionic base to control metabolic acidosis. Hyperlactatemia has also been linked to impaired cellular function and catabolism due to lowering of the cellular redox state and phosphorylation potential. The risk of ``lactate intolerance' is highest in patients with liver failure (impaired lactate clearance) or circulatory shock (increased endogenous lactate production). The use of bicarbonate resulted in better correction of acidosis and lower lactate levels. Also, the incidence of hypotension and other cardiovascular events was lower with bicarbonate. In the subgroup of patients with cardiac failure, mortality tended to be lower with bicarbonate, whereas in the subgroup of septic patents no difference in outcome was found (Suppl Table 36). This effect is most pronounced in patients with circulatory problems and in those with liver dysfunction. The use of acetate has been largely abandoned in view of the associated hemodynamic instability and weight loss, probably related to excessive nitric oxide production and cytokine synthesis. Under normal circumstances, this lactate is metabolized, resulting in adequate correction of acidosis in most patients. In addition, bicarbonate solutions have a higher risk of bacterial contamination and the solution is unstable in the presence of calcium and magnesium. However, with the use of high-permeability membranes, the lower blood side pressures at the end of the dialyzer filter may allow backfiltration of dialysate to the blood,759 raising the possibility of endotoxin or other contaminant exposure. Supplementary material is linked to the online version of the paper at. Increasing filter size, dialysis time, blood flow rate, dialysate flow rate, and/or effluent flow rate should be considered in case of dose inadequacy. The daily arm received a weekly Kt/V approximately two times higher than the alternate-day arm (5. Also overall mortality in the study (34%) was lower than in other studies in this population, suggesting that the results may not generalize. In addition, a significantly higher frequency of hypotension and electrolyte disturbances were seen in the more-intensive arm. Neither study showed improvement in mortality or renal recovery when the dialysis dose was increased, either by increasing Kt/V above 3. This represents a considerably greater intensity of delivered dose than is typically seen in clinical practice. The delivered dose was 88% and 84% of prescribed in the low- and high-dose groups, respectively. Apart from a higher incidence of hypophosphatemia in the high-dose group, the complication rate was similar. The primary end-point was vasopressor dose required to maintain mean arterial pressure at 65 mm Hg. The comparators might be the standard ways to measure dose as Kt/V or prescribed effluent volume.

The Cinco de Mayo festivals, supported first through Marlboro-brand sponsorships and then through Philip Morris support, reached out to leaders as well as to potential consumers. At least 14 of the sponsorships are related to Hispanics81 and include support for dance companies, theater groups, ethnic festivals, an art exposition, conferences, and leadership development. Asian Americans and Pacific Islanders There has been relatively little research about tobacco marketing aimed at Asian Americans and Pacific Islanders. Billboards and stores in predominantly urban Asian American communities have been found to carry more tobacco advertising compared with other urban neighborhoods and to be less likely to carry health warnings compared with white neighborhoods. These sponsorships provided support for the Asian American Expo (in El Monte, California), dinners held by the Congressional Asian Pacific American Caucus in association with presidential inaugural activities, and publication of a directory of Asian Pacific American organizations. Beginning in the 1980s, four major tobacco corporations commissioned reports on the marketing possibilities in the Asian American population groups and found promise of growth markets because of high population growth, high smoking rates in countries 163 "Find Your Voice" campaign for Virginia Slims in Buen Hogar Magazine, 2002 5.

In addition, the majority of convenience store owners in key locations were Asian Americans, making them an important group to cultivate. The heterogeneity of the various population groups and the lack of well-developed Asian American media, however, were barriers to market expansion. First, the "push" strategy would promote trade relations with Asian American business owners through cultural sensitivity training of Philip Morris sales staff, promoting special retail sales materials, and special business-to-business programs involving support of business associations. Second, the "pull" strategy would involve marketing to consumers with special promotions, events such as exhibition of a Marlboro race car and promotions during the Chinese New Year, and tailored advertising materials. One of the themes that emerged as important was upward mobility associated with smoking. However, there is a high rate of menthol cigarette use in some Asian countries and among Asian American youth smokers, second only to African Americans. Reynolds Tobacco Company advertisement for Kauai Kolada variant of Camel cigarettes arm, stated that the brand, although originally imported for Japanese tourists, was also wanted by Asian Americans. Reynolds began a national advertising campaign for a new Camel brand named Kauai Kolada. The advertisements, which appeared in several magazines, including Time, Sports Illustrated, People, and Stuff, featured a hula girl promoting the pineapple- and coconut-flavored cigarette. Although the campaign used Hawaiian imagery, it was likely aimed at a much broader audience. Kauai residents, tobacco control advocates, the governor of Hawaii, and the mayor of Kauai criticized the campaign for being culturally insensitive and using Hawaiian images and the name of Kauai to market cigarettes to young people. The Role of the Media population,111,124 there is almost no published literature on tobacco marketing to American Indians or Alaska Natives. A study by Hodge and colleagues125 found that among 1,000 internet sites selling tobacco, 52 were identified as American Indian sites, with 77% of these sites owned by American Indians. These types of tobacco sales outlets provide colorful and appealing advertisements, easily accessible products, and very low costs. In turn, the individual and tribal owners reap profits that may blunt opposition to or critical awareness of the negative effects of tobacco use among American Indians. There are limited examples of cigarette advertisements that have featured either American Indian themes or images. For example, American Spirit cigarettes liberally use traditional imagery in all their product and promotional materials and provide support for the arts in New Mexico. However, there is no documentation as yet of clear and persistent targeting of American Indians. For example, a Virginia Slims advertisement in the early 1990s featured a man and a woman walking together while the woman looked over her shoulder at a woman behind her. Reynolds to market Camel and Red Kamel to "consumer subcultures" in the San Francisco area between 1995 and 1997. The plans were apparently not carried out, but the documents reveal the interest in these populations.

The balance was challenging because the products and their claims were intended to assuage guilt and prevent health-conscious smokers from quitting, but the lower nicotine levels made it also likely that the users would be less addicted and thus more able to quit. The full-page advertisements appeared to proclaim a technological breakthrough that married taste and low tar. The advertisements were text-heavy to give the impression of science news, with headlines that shouted: "National Smoker Study: Merit Science Works! Models were shown engaging in outdoor activities such as skiing that were in keeping with valuing health. Industry documents suggest it was the marketing impression of well-being, intelligence, and harmony with nature rather than the factual basis that mattered in an era of increasing news about the dangers of smoking. In 1996, 6 of 10 smokers in California thought that these labels indicated low tar or nicotine or a related health claim, and even more smokers used such brands. As noted above, reducing anxiety among smokers has been a major theme in tobacco advertising. The Role of the Media industry documents that have suggested most smokers are unconvinced that lowtar cigarettes are safer, instead lumping all cigarettes together as risky. Reynolds in the 1980s and early 1990s describe efforts to develop additives and technologies that could reduce or mask the odor, visibility, and irritation of secondhand smoke. Reynolds introduced Chelsea cigarettes, which were reintroduced as Horizon in 1990;92 both brands were marketed with identical claims as "the first cigarette that smells good," backed up by "scratch `n sniff" boxes in their advertisements. Several tobacco products have been introduced to address concerns about secondhand smoke. Newer products such as Omni and Accord convey the impression that they have broken away from the others to offer reduced risk to the R. Reynolds claims that Eclipse, a product that looks and can be inhaled like a cigarette, heats rather than burns tobacco. In 2004, its Web site claimed it "may present less risk," "reduces secondhand smoke by 80%," and "leaves no lingering odor" and suggested that the best choice for smokers worried about smoking is to quit and the next-best choice may be Eclipse (see chapter 4). T h e m e s a n d Ta r g e t s o f To b a c c o A d v e r t i s i n g a n d P r o m o t i o n be intended to allow tobacco companies to reinvent themselves as corporations responsive to the criticisms leveled against the industry. Reynolds has recognized the existence and importance of the separate and distinct Jewish market by advertising its products with specially directed copy appeals, promotions, sampling, and other merchandising activities. This has been accomplished through the utilization of the Joseph Jacobs Organization. While compensated as Jewish media sales representatives, they have functioned as a Reynolds advertising agency at no extra cost. The editor of Hadassah Magazine told the New York State Journal of Medicine that their policy of accepting tobacco advertising would continue, despite complaints, "unless the people who say there are surely other sources of revenue, can show them to me. Starting with this issue, we will no longer accept advertisements for tobacco products. We are quitting cigarette ads cold turkey, with a discomfort similar to that felt by smokers who have just quit; the main withdrawal symptom will be the loss of 20 percent of our annual ad revenue.

The initial presentation of cases may be difficult to distinguish from a natural influenza outbreak or other respiratory pathogens. Epidemiological clues to distinguish tularemia from plague or anthrax are the clinical course of disease (slower with tularemia), case fatality rate (higher with plague152 or anthrax153), and possibly the pattern of pulmonary manifestations observed on chest radiograph, such as the large pleural effusions and mediastinal widening characteristic of inhalational anthrax. The variety of clinical manifestations of F tularensis infection and the benefits of early antibiotic intervention necessitate a high degree of suspicion from healthcare providers. Familiarization with the variety of epidemiological and clinical manifestations of this disease, along with available diagnostic tests and countermeasures allow healthcare professionals to minimize the impact of its use.

Although the original research compared obese versus nonobese consumers, Herman, Olmstead, and Polivy (1983) revolutionized research on eating with their insight and empirical data showing that chronic dieting is the driver of most of the effects found between obese and nonobese participants, due to the fact that the obese people were very often chronically dieting.

Yet, between the daily activities of consumers and the ultimate ends to which they aspire there is a vast terrain in which more specific and mundane goals and affect provide direction and energy to behavior. That is, we focus on the motivational and volitional properties of goals and the interplay between goals and affect in consumer behavior. Proposing that consumer behavior is goal-directed seems like arguing that water is wet. Surprisingly, however, even though motivational and volitional concepts abound in the marketing literature, systematic research on goal-directed consumer behavior has been lacking. For example, both abstract goals such as values (Kahle, Beatty, & Homer, 1986; Kamakura & Novak, 1992) and concrete goals important in decision making and information processing (Bettman, 1979; Bettman, Luce, & Payne, 1998; Keller, 1987; see also Fishbach & Dhar, this volume) have been examined. If behaviors such as the purchase of routine products are thought of as the pursuit of simple, unproblematic goals, then attitude-behavior models may be interpreted as models of goal-directed behavior. In fact, these models have often been applied to situations in which the behavior is actually a more long-term, complex goal, such as losing weight (see the review by Sheppard, Hartwick, & Warshaw, 1988). In general, however, understanding goal-directed consumer behavior has not been emphasized in consumer research. Research on affect has a longer tradition in the study of consumer behavior (Bagozzi, Gopinath, & Nyer, 1999; Cohen, Pham, & Andrade, chapter 11, this volume). However, despite the clear linkages between the goals of consumers and the affect they experience, there is little literature on the interface between affect and goal-directed behavior (Bagozzi et al. The chapter focuses on goals that are selected in a reflective manner and pursued consciously, although we acknowledge that there are important and frequent automatic, nonconscious influences on goal pursuit (Chartrand & Bargh, 2002; see also Fishbach & Dhar, chapter 24, this volume). We start with a discussion of important issues related to goals and goaldirected behavior in general. We then turn to affect, distinguishing between endogenous (integral, task-relevant) and exogenous (incidental, ambient) affective influences and considering various functions of affect in goal pursuit. Goals differ from other motivational constructs, such as needs and drives, because they tend to be more concrete and domain-specific, thus exerting a stronger influence on particular consumer behaviors. Although, in the final analysis, high-level goals, such as trying to be independent, converge with terminal values, such as the importance of freedom, goals normally differ from values because they direct and energize behavior actively, rather than merely providing abstract evaluative criteria for appraising objects, events, or actions. Goals are relevant if an attempt to attain a desirable state can fail, or if consumers need to sacrifice something in order to get what they want. Turning off the air conditioner is usually not a goal but an act, but it becomes a goal when it is steaming hot outside and the consumer desires to be environmentally friendly. Following other goal theories, we assume that many of the interesting consumer behaviors are organized around the pursuit of goals, that goals are hierarchically structured from lower to higher levels, that goal-directed behavior is characterized by effort expenditure and persistence in the face of temptations and interruptions, and that goals are accessible to conscious awareness, although they need not always be top-of-mind during goal pursuit (Austin & Vancouver, 1996; Emmons, 1996; Locke & Latham, 1990). Before discussing how goal pursuit takes place, we examine goal features and goal structure. First, we discuss several goal features that characterize and distinguish the goals that consumers pursue. Second, since goal-directed behavior usually involves many different goals at varying levels, we describe how goals are organized. Features of Goals Individual goals have several features that give them meaning and account for their influence on behavior, and also distinguish them from each other (Austin & Vancouver, 1996; Emmons, 1989; Little, 1983; Winell, 1987). We will briefly discuss the features of goal content, desirability, importance, and feasibility. Winell (1987), for instance, distinguishes goals related to different life domains such as career, family, social/community, leisure, and material/environment. Emmons (1996) lists 12 general categories of goals, including achievement, affi liation/intimacy, power, independence, and self-presentation. Because goals are internal representations of desired states to be attained or undesirable states to be avoided, the desirability of a goal is an important motivational dimension. Although avoidance goals focus on undesirable states, successful pursuit of these goals can be highly desirable, and some goals are more desirable than others. The affect associated with a goal is an important determinant of goal desirability, and this issue will be discussed in greater detail below. That is, goals may be highly desirable, such as having the right salad dressing, but not very important in the larger scheme of things. The distinction between goal desirability and importance is analogous to the distinction between the valence and strength dimensions of attitudes (Petty & Krosnick, 1995). One way to conceptualize importance is as the discrepancy between the current state of affairs and a desired state. The greater the discrepancy is perceived to be, the more important the goal is expected to be to the person. Commitment to the goal is particularly important when people do not freely choose their goals, but the goals are assigned to them. Constructs subsumed under this term include various forms of expectancies, probability of success, confidence, self-efficacy, controllability, and ease or difficulty of goal achievement. Skinner (1996) proposed a useful distinction between agents (the person exerting control), means (pathways through which control is exerted), and ends (outcomes over which control is exerted) of control, and classifies the various control constructs found in the literature by whether they refer to agent-means, agent-ends, or means-ends relations. Agent-ends relations are beliefs held by agents that they can attain desired and avoid undesired outcomes. Organization of Goals Goals are organized in semantic networks, with goals and their means as nodes and the relationships between them as linkages. Although goal structures are latent, hypothetical constructs, we can distinguish horizontal and vertical dimensions in them. The horizontal dimension in goal structures represents the degree of similarity, relatedness or conceptual overlap between goals, based on goal content.

One important caveat to muscle relaxant 8667 generic rumalaya gel 30 gr amex muscle relaxant vecuronium rumalaya gel 30 gr low cost the above discussion is that cognitive processing can go awry even when an appropriate match between the task and the cognitive system is in place spasms of the diaphragm buy rumalaya gel 30gr line. The choice goals framework clearly notes that even with purely analytical tasks, maximal payoffs from cognitive processing rely on decision makers selecting information that is most diagnostic. Prior work has found that decision makers appear to make adaptive choices of information across task environments, but these processes of selectivity are by no means perfect, particularly when task environments are misleading. Similarly, recent work on System 1 processes notes that the particular "thin slice" of behavior or information on which System 1 processes are focused has huge implications for the ultimate quality of the relevant decisions (Gladwell, 2005). In summary, relationships among decision metagoals appear to differ for intuitive versus analytical tasks. Analytical tasks have been the typical focus of the choice goals framework to date. These tasks are characterized by relatively straightforward effort-accuracy tradeoffs in decision strategy selection. Specifically, decision makers appear to approximate an efficient frontier where increased decision effort generally produces increased task accuracy. This is particularly true when attention is focused on appropriate or diagnostic inputs. In these situations, goals to minimize negative emotion often decrease decision performance because they reduce reliance on explicit decision tradeoffs. However, the impact of emotion depends on the particular direction of coping efforts. Emotion may often function as a signal generating increased effort consistent with problem-focused coping, but it often simultaneously causes avoidance of tradeoffs consistent with emotion-focused coping. Finally, accountability goals should generally increase effort allocation, and hence accuracy, unless special conditions are met. Conversely, intuitive tasks appear to be characterized by a fundamental change in the relationships among decision metagoals. Intuitive tasks are defi ned as those tasks that are performed more accurately by System 1 (vs. Thus, increased conscious effort (which must be System 2 by definition) should at best dilute the efforts of System 1. Thus, the fundamental relationship postulated and explored by the effort-accuracy paradigm will be reversed. In these cases, factors such as increased cognitive load or cognitive distraction may lead to more decision accuracy (Dijksterhuis, 2004). Similarly, these situations are often associated with reduced performance given accountability (McMackin & Slovic, 2000; Wilson & Schooler, 1991), presumably because accountability instructions recruit increased cognitive effort. In these situations, the effects of increased emotion are again likely to be moderated by the particular coping strategies available (and chosen). We argue that decision strategy selection is shaped by goals to maximize accuracy, minimize effort, minimize negative emotion and maximize justifiability and that individuals adaptively respond to task characteristics in order to balance these four metagoals when selecting among available decision strategies. We extend our choice goals framework by considering high-stakes decision contexts, where the four choice goals are likely to be in substantial conflict. In these environments, it is difficult to generate prescriptions regarding increased decision performance, as intervention along the lines of one goal (increase justification) may cause difficulties with respect to another goal (increased emotional threat). This extension also points out the challenge of integrating nonconscious, automatic cognitive processes into our framework. Consideration of these processes further underscores the importance of a task analysis in general and a distinction between intuitive and analytical tasks in particular. This task distinction will determine how choice metagoals interact, for instance, whether increased effort or justification can in fact be expected to increase performance accuracy.
