But other studies suggest that Head Start and similar programs may improve emotional intelligence and reduce the likelihood that children will drop [42] out of school or be held back a grade (Reynolds discount 100mg aurogra otc erectile dysfunction treatment pune, Temple best aurogra 100 mg erectile dysfunction pumps review, Robertson, & Mann 2001). Intelligence is improved by education; the number of years a person has spent in school [43] correlates at about r =. It is important to remember that the relative roles of nature and nurture can never be completely separated. A child who has higher than average intelligence will be treated differently than a child who has lower than average intelligence, and these differences in behaviors will likely amplify initial differences. This means that modest genetic differences can be multiplied into big differences over time. Psychology in Everyday Life: Emotional Intelligence Attributed to Charles Stangor Saylor. Emotional intelligence refers to the ability to accurately identify, assess, and understand emotions, as well as to effectively control one’s own emotions (Feldman-Barrett & Salovey, [46] 2002; Mayer, Salovey, & Caruso, 2000). The idea of emotional intelligence is seen in Howard Gardner‘sinterpersonal intelligence (the capacity to understand the emotions, intentions, motivations, and desires of other people) and intrapersonal intelligence (the capacity to understand oneself, including one‘s emotions). There are a variety of measures of emotional intelligence (Mayer, Salovey, & Caruso, 2008; Petrides & Furnham, [48] 2000). One popular measure, the Mayer-Salovey-Caruso Emotional Intelligence Test (http://www. When his supervisor brought him an additional project, he felt ____ (fill in the blank). Although it has been found that people with higher emotional intelligence are [50] also healthier (Martins, Ramalho, & Morin, 2010), findings are mixed about whether emotional intelligence [51] predicts life success—for instance, job performance (Harms & Credé, 2010). Furthermore, other researchers have questioned the construct validity of the measures, arguing that emotional intelligence really measures knowledge [52] about what emotions are, but not necessarily how to use those emotions (Brody, 2004), and that emotional intelligence is actually a personality trait, a part of g, or a skill that can be applied in some specific work situations— [53] for instance, academic and work situations (Landy, 2005). Although measures of the ability to understand, experience, and manage emotions may not predict effective behaviors, another important aspect of emotional intelligence—emotion regulation—does. Emotion regulation refers to the ability to control and productively use one‘s emotions. Research has found that people who are better able to override their impulses to seek immediate gratification and who are less impulsive also have higher cognitive and social intelligence. Because emotional intelligence seems so important, many school systems have designed programs to teach it to their students. However, the effectiveness of these programs has not been rigorously tested, and we do not yet know whether emotional intelligence can be taught, or if learning it would improve the quality of people‘s lives (Mayer & [55] Cobb, 2000). People who are better able to regulate their behaviors and emotions are also more successful in their personal and social encounters. Give some examples of how emotional intelligence (or the lack of it) influences your everyday life and the lives of other people you know.

Most people in Western cultures tend to agree with the idea that intelligence is an important personality variable that should be admired in those who have it. But people from Eastern cultures tend to place less emphasis on individual intelligence and are more likely to view intelligence as reflecting wisdom and the desire to improve the society as a whole rather than only themselves (Baral & Das, 2004; Sternberg, [1] 2007). And in some cultures, such as the United States, it is seen as unfair and prejudicial to argue, even at a scholarly conference, that men and women might have different abilities in domains such as math and science and that these differences might be caused by genetics (even though, as we have seen, a great deal of intelligence is determined by genetics). In short, although psychological tests accurately measure intelligence, it is cultures that interpret the meanings of those tests and determine how people with differing levels of intelligence are treated.

Pharmacodynamics Pharmacodynamics is a drug’s effect on the physiology of the cell and the mech- anism that causes the pharmaceutical response order aurogra online pills erectile dysfunction treatment san francisco. Its secondary effect is to depress the cen- tral nervous system causing drowsiness cheap aurogra 100mg with visa impotence vs infertile. The secondary effect is desirable if the patient needs bedrest, but undesirable if the patient is driving a car. A period of time passes after a drug is administered until the pharmaceutical response is realized. The onset time response is the time for the minimum concentration of drug to cause the initial pharmaceutical response. The peak time response is when the drug reaches its highest blood or plasma concentration. Duration is the length of time that the drug maintains the pharmaceutical response. All three parameters are used when administering the drug in order to determine the therapeutic range— when the drug will become effective, when it will be most effective, and when the drug is no longer effective. For example, the time–response curve of an analgesic is used for pain man- agement. Once the peak response time is reached, the effectiveness of the drug to block pain diminishes. The time–response curve indicates when the phar- maceutical response is no longer present requiring that an additional dose be administered to the patient. The activity of the drug is determined by the drug’s ability to bind to a specific receptor. Depending on the drug, binding either initiates a physiological response by the cell or blocks a cell’s physio- logical response. Rapid-Cell Membrane-Embedded Enzymes: A drug binds to the sur- face of the cell causing an enzyme inside the cell to initiate a physio- logical response. Rapid-Ligand-Gated Ion Channels: The drug spans the cell membrane causing ion channels within the membrane to open resulting in the flow of primarily sodium and calcium ions into and out of the cell. This in turn causes an enzyme inside the cell to initiate a physiological response or causes the opening of the ion channel. A drug that causes a physiological response is called an agonist and a drug that blocks a physiological response is referred to as an antagonist. An inhibitory action of 50 (I50) indicates that the drug effec- tively inhibits the receptor response in 50% of the population. Cholinergic receptors are located in the blad- der, heart, blood vessels, lungs, and eyes. A drug that is given to stimulate the cholinergic receptors will decrease the heart rate and blood pressure, increase gastric acid secretion, constrict bronchioles, increase urinary bladder contraction, and con- strict the pupils. Categories of Drug Action Drugs are categorized by the type of action it causes on the body. These are drugs that replace an essential body compound such as insulin or estrogen. These drugs interfere with bacterial cell and limit bacterial growth or eliminate the bacteria, such as penicillin. These drugs irritate cells to cause a natural response that has a therapeutic effect such as a laxative that irritates the colon wall to increase movement of the colon resulting in defecation. Therapeutic Index and Therapeutic Range Drugs have a pharmaceutical response as long as the dose remains within the drug’s margin of safety. This means that a patient can be given a wide range of dose levels without experiencing a toxic effect. Other drugs have a narrow margin of safety where a slightest change in the dose can result in an undesirable adverse side effect. These drugs require that levels in the plasma be monitored and adjustments are made to the dosage in order to prevent a toxic effect from occurring. The plasma drug levels must be within the therapeutic range, which is also known as the therapeutic window. Peak levels indicate the rate a drug is absorbed in the body and is affected by the route used to administer the drug. Drugs administered intravenously have a fast peak drug level while a drug taken orally has a slow peak drug level because the drugs needs time to be absorbed and distributed. Blood samples are drawn at peak times based on the route used to administer the drug. The trough level is the lowest plasma concentration of the drug and measures the rate at which the drug is eliminated. Blood should be drawn immediately before the next dose is given regardless of the route used to administer the drug. Side Effects A drug can have a side effect in addition to its pharmaceutical response. A severe undesirable side effect is referred to as an adverse reaction that occurs unintentionally when a normal dose of the drug is given to a patient. For example, an adverse reaction might be anaphylaxis (cardiovascular collapse) Some adverse reactions are predictable by age and weight of the patient. Young children and the elderly are highly responsive to medications because of an immature or decline in hepatic and renal function. Women typically are smaller than men and have a different propor- tion of fat and water which affects absorption and distribution of the drug. Cold, heat, sensory deprivation or overload, and oxygen depriva- tion in high altitude create environmental factors that might interact with a drug. A drug might be influenced by the presence or absence of food in the patient’s gastrointestinal tract or by the patient’s cortio- costeroid secretion rhythm. In addition, circadian cycle, urinary excretion pat- tern, fluid intake, and drug metabolizing enzyme rhythms all might influence a drug’s effect. A drug can react differently if the patient is experiencing pain, anxiety, circulatory distress, or hepatic and/or renal dysfunction. This is an abnormal response that is unpredictable and unex- plainable that could result from the patient overresponding or underresponding to the drug or the drug having an effect that is different from what is expected. The patient has a decreased physiologic response after repeated administration of the drug. With a physical dependency, the patient experiences an intense physical distur- bance when the drug is withdrawn. With psychological dependency, the patient develops an emotional reliance on the drug. The administration of one drug increases or decreases the pharmaceutical response of a previously administered drug. A more desirable pharmaceutical response is achieved through the interaction of two drugs that are administered.

Occasionally order aurogra online from canada erectile dysfunction causes smoking, the hands or arms may be raised to protect the body against the stabbing motion purchase aurogra 100mg with visa impotence quitting smoking, resulting in stab wounds to the defense areas. In blunt-force attacks, the injuries sustained usually take the form of bruises if the victim is being punched or kicked, but there may also be abra- sions and/or lacerations depending on the nature of the weapon used. If the victim is lying on the ground while being assaulted, he or she will tend to curl up into a fetal position to protect the face and the front of the trunk, particu- larly from kicks. In these circumstances, defensive bruising is likely to be seen on other surfaces of the trunk and limbs. The absence of defense injuries in persons otherwise apparently capable of defending themselves against an assault may be particularly significant if it is believed that other injuries found on the victim could have been self- inflicted or if it is believed that they were incapacitated through alcohol, drugs, or other injury. The declaration also established guidelines for doctors when faced with cases of suspected torture. Clinicians view torture in two main contexts: first, torture that is perpetrated by criminals and terrorist orga- nizations, and second, torture that is carried out, or allegedly carried out, by the police or other security force personnel during the detention and interro- gation of prisoners and suspects. Injury Assessment 149 Criminal groups and paramilitary organizations may torture their cap- tives for numerous reasons. It may be to extract information from an opposing gang or faction, to discipline informants and others engaged in unsanctioned criminal activity, or simply to instill fear and division within a community. The victim is usually bound, blind- folded, and gagged, and the wrists and ankles may bear the pale streaky linear bruises and abrasions caused by ligatures. Black eyes, fractures of the nose and jaws, and dislodgment of the teeth are all fairly typi- cal. Cigarette burns, usually seen as discrete circular areas of reddish-yellow, parchmented skin, are also quite common. Patterned injuries resulting from being struck with the butt of a gun or tramline bruising owing to blows with a truncheon or baseball bat may be seen; in Northern Ireland, shooting through the lower limbs (“knee-capping”) is a favored method of punishment by para- military organizations. Systematic torture by security personnel, usually during interrogation of suspects, ranges from the subtle use of threats and intimidation to physical violence. Hooding, prolonged standing, and the use of high-pitched sound have all been used, as have attempts to disorientate prisoners by offering food at erratic times, frequent waking up after short intervals of sleep, and burning a light in the cell 24 hours a day. Physical abuse includes beating of the soles of the feet, so-called falanga, which, although extremely painful and debilitating, does not usually cause any significant bruising. Repeated dipping of the victim’s head under water, known as submarining, may prove fatal if prolonged, as can the induction of partial asphyxia by enveloping the head in a plastic bag. Electric torture is well documented and carries the risk of local electric shocks and fatal electrocution. Telefono, as it is known in Latin America, con- sists of repeated slapping of the sides of the head by the open palms, resulting in tympanic membrane rupture. Doctors who have access to prisoners in custody have a heavy responsi- bility to ensure that they are properly treated during detention and interroga- tion. In all cases of suspected or alleged ill-treatment of prisoners, it is essential that the doctor carry out a methodical and detailed “head-to-toe” examina- tion. All injuries and marks must be accurately recorded and photographed, and the appropriate authorities must be informed immediately. Increasingly, forensic physicians are involved in assessments of refugees and asylum seek- ers to establish whether accounts of torture (both physical and psychologi- cal) are true. This role is likely to expand in the future, and the principles of independent assessment, documentation, and interpretation are, as with other 150 Payne-James et al. Introduction The term bite mark has been described as “a mark caused by the teeth alone, or teeth in combination with other mouth parts” (10). Recog- nition, recording, analysis, and interpretation of these injuries are the most intriguing challenges in forensic dentistry. Biting can establish that there has been contact between two people—the teeth being used for offense or defense. When individual tooth characteristics and traits are present in the dentition of the biter and are recorded in the biting injury, the forensic significance of the bite mark is greatly increased. Early involvement of the forensically trained dentist, with experience in biting injuries, is essential to ensure that all dental evidence from both the victim and any potential suspect(s) is appropriately collected, preserved, and evaluated. There may be insufficient evidence to enable comparisons to be made with the biting edges of the teeth of any par- ticular person, but, if the injury can be identified as a human bite mark, it may still be significant to the investigation. It is important that the forensic dentist discusses with investigators the evidential value of the bite mark to enable resources to be wisely used. Clearly, conclusions and opinions expressed by the forensic dentist often lead him or her into the role of the expert witness subject to rigorous examination in court. The forensic physician will mostly be involved with biting injuries to human skin and any secondary consequences, including infection and disease transmission, but should be aware that bites in foodstuffs and other materials may be present at a crime scene and be easily overlooked. It is essential that a human bite can be distinguished from an animal bite, thus exonerating (or incriminating) the dog or cat next door. The following sections will consider issues surrounding bites to human skin caused by another human. Early rec- ognition of a patterned injury (suspected of being caused by biting) by medi- cal personnel, social services, and other investigating agencies is extremely important; the injury may be the only physical evidence and must not be lost. Ideally, the forensic dentist should be contacted sooner rather than later when a possible biting injury is discovered to ensure that all evidence is collected appropriately. All too often the dentist is brought in at a later date, when there has been incorrect recording of the bite mark and the injury is partly healed and distorted or fully healed and no longer visible. Reliance may then have to be placed on ultraviolet photography to demonstrate the “lost” injury (11). Injury Assessment 151 Bites can be found on the victim or the assailant (living, deceased, child, or adult). It is well known that biting is often a feature in nonaccidental injury to children (see Chapter 5). If a bite mark is found on an anatomical site that is accessible to the victim, it becomes necessary to exclude him or her from the investigation. If the answer to the first question is “don’t know,” “possibly,” or “yes,” then request the assistance of the forensic dentist. Ensure that swabs are taken from the injured site (with controls) and photographs should be taken. Make sure that you know which forensic dentists are available in your area; this will prevent delays and frustration. You will need to know whether your local forensic dentist has experience and training in bite mark-analysis or whether he or she focuses mainly on identifications. The forensic dentist will examine the suspected biting injury and con- sider the following: • Whether the injury is oval or round. However, note that a mark from only one arch does not mean that it is not a biting injury.

If the lateral part of the hypothalamus is damaged order aurogra australia erectile dysfunction doctors tucson az, the animal will not eat even if food is present purchase generic aurogra pills erectile dysfunction agents, whereas if the ventromedial part of the [3] hypothalamus is damaged, the animal will eat until it is obese (Wolf & Miller, 1964). Glucose is the main sugar that the body uses for energy, and the brain monitors blood glucose levels to determine hunger. Glucose levels in the bloodstream are regulated by insulin, a hormone secreted by the pancreas gland. When insulin is low, glucose is not taken up by body cells, and the body begins to use fat as an energy source. Eating and appetite are also influenced by other hormones, including orexin, ghrelin, and leptin (Brennan & [4] Mantzoros, 2006; Nakazato et al. Normally the interaction of the various systems that determine hunger creates a balance or homeostasis in which we eat when we are hungry and stop eating when we feel full. But homeostasis varies among people; some people simply weigh more than others, and there is little Attributed to Charles Stangor Saylor. Weight is determined in large part by thebasal metabolic rate, the amount of energy expended while at rest. Each person‘s basal metabolic rate is different, due to his or her unique physical makeup and physical behavior. A naturally occurring low metabolic rate, which is determined entirely by genetics, makes weight management a very difficult undertaking for many people. When researchers rigged clocks to move faster, people got hungrier and ate more, as if they thought they must be hungry again because so [5] much time had passed since they last ate (Schachter, 1968). And if we forget that we have already eaten, we are likely to eat again even if we are not actually hungry (Rozin, Dow, [6] Moscovitch, & Rajaram, 1998). Current norms for women in Western societies are based on a very thin body ideal, emphasized by television and movie actresses, models, and even children‘s dolls, such as the ever-popular Barbie. These norms for excessive thinness are very difficult for most women to attain: Barbie‘s measurements, if translated to human proportions, would be about 36 in. Many women idealize being thin and yet are unable to reach the standard that they prefer. Eating Disorders In some cases, the desire to be thin can lead to eating disorders, which are estimated to affect about 1 million males and 10 million females the United States alone (Hoek & van Hoeken, [8] 2003; Patrick, 2002). Anorexia nervosais an eating disorder characterized by extremely low body weight, distorted body image, and an obsessive fear of gaining weight. Anorexia begins with a severe weight loss diet and develops into a preoccupation with food and dieting. Bulimia involves repeated episodes of overeating, followed by vomiting, laxative use, fasting, or excessive exercise. It is most common in women in their late teens or early 20s, and it is often accompanied by depression and anxiety, particularly around the time of the binging. The cycle in which the person eats to feel better, but then after eating becomes concerned about weight gain and purges, repeats itself over and over again, often with major psychological and physical results. Eating disorders are also related psychological causes, including low self-esteem, perfectionism, and the perception that one‘s body weight is [11] too high (Vohs et al. Because eating disorders can create profound negative health outcomes, including death, people who suffer from them should seek treatment. Obesity Although some people eat too little, eating too much is also a major problem. Obesity is a medical condition in which so much excess body fat has accumulated in the body that it begins to have an adverse impact on health. In addition to causing people to be stereotyped and treated [13] less positively by others (Crandall, Merman, & Hebl, 2009), uncontrolled obesity leads to health problems including cardiovascular disease, diabetes, sleep apnea, arthritis, Alzheimer‘s disease, and some types of cancer (Gustafson, Rothenberg, Blennow, Steen, & Skoog, [14] [15] 2003). Its prevalence is rapidly increasing, and it is one of the most serious public health problems of the 21st century. Although obesity is caused in part by genetics, it is increased by overeating and a lack of physical activity (Nestle & Jacobson, [16] 2000; James, 2008). There are really only two approaches to controlling weight: eat less and exercise more. Dieting is difficult for anyone, but it is particularly difficult for people with slow basal metabolic rates, who must cope with severe hunger to lose weight. Although most weight loss can be maintained for about a year, very few people are able to maintain substantial weight loss through dieting alone [17] for more than three years (Miller, 1999). Substantial weight loss of more than 50 pounds is typically seen only when weight loss surgery has been performed (Douketis, Macie, Thabane, & [18] Williamson, 2005). Weight loss surgery reduces stomach volume or bowel length, leading to earlier satiation and reduced ability to absorb nutrients from food. Although dieting alone does not produce a great deal of weight loss over time, its effects are substantially improved when it is accompanied by more physical activity. People who exercise regularly, and particularly those who combine exercise with dieting, are less likely to be obese [19] (Borer, 2008). Exercise increases cardiovascular capacity, lowers blood pressure, and helps improve diabetes, [20] joint flexibility, and muscle strength (American Heart Association, 1998). Exercise also slows the cognitive impairments that are associated with aging (Kramer, Erickson, & Colcombe, [21] 2006). Because the costs of exercise are immediate but the benefits are long-term, it may be difficult for people who do not exercise to get started. It is important to make a regular schedule, to work exercise into one‘s daily activities, and to view exercise not as a cost but as an opportunity to Attributed to Charles Stangor Saylor. Exercising is more fun when it is done in groups, [23] so team exercise is recommended (Kirchhoff, Elliott, Schlichting, & Chin, 2008). A recent report found that only about one-half of Americans perform the 30 minutes of exercise 5 times a week that the Centers for Disease Control and Prevention suggests as the minimum [24] healthy amount (Centers for Disease Control and Prevention, 2007). As for the other half of Americans, they most likely are listening to the guidelines, but they are unable to stick to the regimen. Almost half of the people who start an exercise regimen give it up by the 6-month mark [25] (American Heart Association, 1998). This is a problem, given that exercise has long-term benefits only if it is continued. Sex: The Most Important Human Behavior Perhaps the most important aspect of human experience is the process of reproduction. Successful reproduction in humans involves the coordination of a wide variety of behaviors, including courtship, sex, household arrangements, parenting, and child care. The Experience of Sex The sexual drive, with its reward of intense pleasure in orgasm, is highly motivating. The [26] biology of the sexual response was studied in detail by Masters and Johnson (1966), who monitored or filmed more than 700 men and women while they masturbated or had intercourse. Masters and Johnson found that the sexual response cycle—the biological sexual response in humans—was very similar in men and women, and consisted of four stages: Excitement. Women‘s breasts and nipples may enlarge and the vagina expands and secretes lubricant. Muscular contractions occur throughout the body, but particularly in the genitals.
