Tis included work by Faraday, Geissler, and Hittof in creating and developing the frst high-tension electrical evacu- ated tubes, which produced what were named cathode rays within the device. Te cathode rays produced a spark caused by a stream of high-speed electrons traversing a small gap and striking a metal target. Tis work was followed by Sir William Crookes and Professor Heinrich Hertz, who demonstrated that 187 188 Forensic dentistry cathode rays produced forescence and heat within and without the tube. However, Röentgen did, in fact, discover that other invisible rays emanating from the device possessed the ability to penetrate solid objects and produce photographic shadows of fesh and bones. When there is a confict between the written dental record and antemortem radiographs of a subject, deference is given to the radiographs as the gold standard having less potential for human error than charted dental information. Tis chapter on the basic theory of dental radiography is presented at a level such that the principles pertinent to the topics and themes most important to forensic dental investi- gations are emphasized. Tus, electrical energy is converted to kinetic energy, which is then converted to electromagnetic energy. Only 1% or less of the bombarding electron energy is converted into x-radiation, with the remaining energy resulting in a very large gain of heat, which is the greatest cause of tube failure. Tis fact accounts for the absolute need to follow the manufacturer’s recommended duty cycle by waiting the specifed amount of time between exposures. Te setting of a mass disaster morgue is more likely to destroy a tube head than working on typical dental patients, where the time for placing flms afer each exposure helps protect the duty cycle. Te resulting x-ray beam is comprised of millions of photons of vary- ing energy (wavelengths) and is referred to as having a continuous or poly- chromatic spectrum. Older x-ray units produce even more variation in the uniformity of the beam as the alternating current rises and falls. Tese units are more ef- cient and provide more high-energy, diagnostically useful photons and cut exposure times roughly in half. Older units also have difculty in producing the extremely short exposure times (usually tenths of a second) required by digital x-ray sensors, which require signifcantly less radiation than flm. One very simple but efective method to accomplish this is to cover the opening of the tube head collimator in an old unit with round sections of rare earth screen material until the beam is weakened sufciently to allow longer expo- sure settings comparable to the unit’s timer capabilities. Terefore, there is always a varying amount of magnifcation of the object in any plane flm image. Te degree of magnifcation is determined by the ratio of the x-ray source-to-object distance and source-to-flm distance. Te larger the distance from the source to the image receptor, the less magnifcation occurs. Likewise, the closer the object to the receptor, the less the magnif- cation and the sharper the image will be. Tat is because the energy of the quickly diverging beam will weaken mathematically as a square of its distance. Terefore, changing the distance of an individual to the x-ray source from 1 foot to 4 feet reduces the dose or intensity of the radiation to 1/16th of the original dose. New technology in the form of handheld generators that are truly pow- ered by direct current from rechargeable batteries is now in great use in forensic dentistry (Aribex™ Nomad™) but will be discussed further later in this chapter and in other chapters in this textbook. Terefore, the total of the external and internal structures of the object is represented in the image and not simply the surface area. Tis is signifcant in that a radiographic image reveals objects that cannot be per- ceived with the naked eye. Tis also means, however, that dental radiographic images require interpretation by the observer because the image is presented as a two-dimensional representation of a three-dimensional object. Radiographic images of the teeth and maxillofacial structures can only be created due to the fact that the beam of electromagnetic energy is attenu- ated in varying degrees, depending on the absorption characteristics of dif- ferent structures through which it passes, and that recording media will react diferently depending on the energy received.

Descriptions of healthy eating tend to describe food in terms of broader food groups and make recommendations as to the relative consumption of each of these groups as follows 75mg doxepin for sale. Other recommendations for a healthy diet include a moderate intake of alcohol (a maximum of 3–4 units per day for men and 2–3 units per day for women) buy doxepin 75 mg otc, the consump- tion of fluoridated water where possible cheap 25 mg doxepin free shipping, a limited salt intake of 6g per day, eating unsaturated fats from olive oil and oily fish rather than saturated fats from butter and margarine and consuming complex carbohydrates (e. It is also recommended that men aged between 19 and 59 require 2550 calories per day and that similarly aged women require 1920 calories per day although this depends upon body size and degree of physical activity (DoH 1995). Diet is linked to health in two ways: by influencing the onset of illness and as part of treatment and management once illness has been diagnosed. Eating disorders are linked to physical problems such as heart irregularities, heart attacks, stunted growth, osteoporosis and reproduction. Obesity is linked to diabetes, heart disease and some forms of cancer (see Chapter 15). In addition, some research suggests a direct link between diet and illnesses such as heart disease, cancer and diabetes (see Chapters 14 and 15). Much research has addressed the role of diet in health and although at times controversial, studies suggest that foods such as fruits and vegetables, oily fish and oat fibre can be protective whilst salt and saturated fats can facilitate poor health. Diet and treating illness Diet also has a role to play in treating illness once diagnosed. Obese patients are mainly managed through dietary based interventions (see Chapter 15). Patients diagnosed with angina, heart disease or following a heart attack are also recommended to change their lifestyle with particular emphasis on stopping smoking, increasing their physical activity and adopting a healthy diet (see Chapter 15). Dietary change is also central to the management of both Type 1 and Type 2 diabetes. Dietary interventions are also used to improve the self-management of diabetes and aim to encourage diabetic patients to adhere to a more healthy diet. A healthy diet therefore consists of high carbohydrate and low fat intake and links have been found between diet and both the onset of illnesses and their effective management. However, research indicates that many people across the world do not eat according to these recommendations. Therefore, dietary recommendations aimed at the Western world in the main emphasize a reduction in food intake and the avoidance of becoming overweight. For the majority of the developing world, however, undereating remains a problem resulting in physical and cognitive problems and poor resistance to illness due to lowered intakes of both energy and micronutrients. Recent data from the World Health Organization indicate that 174 million children under the age of 5 in the developing world are malnourished and show low weight for age and that 230 million are stunted in their growth. Such malnutrition is the highest in South Asia which is estimated to be five times higher than in the Western hemisphere, followed by Africa then Latin America. One large scale study carried out between 1989–90 and 1991–92 examined the eating behaviour of 16,000 male and female students aged between 18 and 24 from 21 European countries (Wardle et al. The results suggest that the prevalence of these fairly basic healthy eating practices was low in this large sample of young adults. In terms of gender differences the results showed that the women in this sample reported more healthy eating practices than the men. The results also provided insights into the different dietary practice across the different European countries. Overall, there was most variability between countries in terms of eating fibre, red meat, fruit and salt. Countries such as Sweden, Norway, The Netherlands and Denmark ate the most fibre, whilst Italy, Hungary, Poland and Belgium ate the least. Mediterranean countries such as Italy, Portugal and Spain ate the most fruit and England and Scotland ate the least. Further, Belgium and Portugal made least attempts to limit red meat whilst Greece, Austria, Norway and Iceland made more attempts. Finally, salt consumption was highest in Poland and Portugal and lowest in Sweden, Finland and Iceland. The elderly: Research exploring the diets of the elderly indicate that although many younger and non institutionalised members of this group have satisfactory diets many elderly people particularly the older elderly report diets which are deficient in vitamins, too low in energy and have poor nutrient content. This chapter will describe developmental models, cognitive models and the role of weight concern in understanding eating behaviour (see Figure 6. The work was conducted at a time when current feeding policies endorsed a very restricted feeding regime and Davis was interested to examine infants’ responses to a self selected diet. The children were offered a variety of 10 to 12 healthy foods prepared without sugar, salt or seasoning and were free to eat whatever they chose. Her detailed reports from this study showed that the children were able to select a diet consistent with growth and health and were free from any feeding problems. The results from this study generated a theory of ‘the wisdom of the body’ which emphasized the body’s innate food preferences. In line with this, Davis concluded from her data that children have an innate regulatory mechanism and are able to select a healthy diet.

These studies support a cross-behavioural perspective of addictions and suggest an interrelationship between different behaviours cheap doxepin 25mg overnight delivery. It is possible that because women dieters may use smoking as a means to reduce their eating they develop an association between these behaviours quality 10 mg doxepin. It is also possible that the substitution between addictive behaviours may also exist between other behaviours such as alcohol and smoking (stopping smoking increases drinking) discount doxepin 75mg otc, or gambling and eating (stopping gambling increases eating). There are many different theories to explain why people smoke or drink and how they can be encouraged to adopt healthy behaviours. This chapter examined the different models of addiction, including the moral model, the disease models and the social learning perspective. Finally, this chapter examined the interrelationship between different behaviours, in particular smoking and eating, to examine the validity of a cross- behavioural perspective. Theories of addictions and addictive behaviour emphasize either the psychological or physiological processes. This separation is reflected in the differences between the disease models and the social learning perspectives. It is often assumed that the most recent theoretical perspective is an improvement of previous theories. In terms of addictive behaviours, the moral model is seen as more naïve than the disease model, which is more naïve than a social learning theory perspective. However, perhaps these different models also illustrate different (and not necessarily better) ways of explaining behaviour and of describing the individual. This book examines the different theories of addictive behaviours and in particular outlines the contribution of social learning theory. This book provides a detailed analysis and background to relapse prevention and applies this approach to a variety of addictive behaviours. This book illustrates the extent to which different addictive behaviours share common variables in both their initiation and maintenance and discusses the interrelationship between physiological and psychological factors. This is a very clearly written accessible book which describes physiological and psychosocial reasons for smoking and provides an excellent account of smoking cessation strategies. Three main psychological perspectives which have been used to study food intake are then described. First, the chapter describes developmental models of eating behaviour with their focus on exposure, social learning and associative learning. Second, it examines cognitive theories with their emphasis on motivation and social cognition models. Third, it explores the emphasis on weight concern and the role of body dissatisfaction and restrained eating. Dinner is later described as similar to breakfast with ‘no vegetables, boiled meat, no made dishes being permitted much less fruit, sweet things or pastry. Similarly in the 1840s Dr Kitchener recommended in his diet book a lunch of ‘a bit of roasted poultry, a basin of good beef tea, eggs poached. Nowadays, there is, however, a consensus among nutritionists as to what constitutes a healthy diet (DoH 1991). Food can be considered in terms of its basic constituents: carbohydrate, protein, alcohol and fat. Descriptions of healthy eating tend to describe food in terms of broader food groups and make recommendations as to the relative consumption of each of these groups as follows. Other recommendations for a healthy diet include a moderate intake of alcohol (a maximum of 3–4 units per day for men and 2–3 units per day for women), the consump- tion of fluoridated water where possible, a limited salt intake of 6g per day, eating unsaturated fats from olive oil and oily fish rather than saturated fats from butter and margarine and consuming complex carbohydrates (e.

Explain how molecular genetics research helps us understand the role of genetics in personality doxepin 25 mg. One question that is exceedingly important for the study of personality concerns the extent to which it is the result of nature or nurture buy doxepin 25mg fast delivery. If nature is more important generic doxepin 75mg overnight delivery, then our personalities will form early in our lives and will be difficult to change later. If nurture is more important, however, then our experiences are likely to be particularly important, and we may be able to flexibly alter our personalities over time. In this section we will see that the personality traits of humans and animals are determined in large part by their genetic makeup, and thus it is no surprise that identical twins Paula Bernstein and Elyse Schein turned out to be very similar even though they had been raised separately. A gene is the basic biological unit that transmits characteristics from one generation to the next. These common genetic structures lead members of the same species to be born with a variety of behaviors that come naturally to them and that define the characteristics of the species. These abilities and characteristics are known as instincts—complex inborn patterns [1] of behaviors that help ensure survival and reproduction(Tinbergen, 1951). Birds naturally build nests, dogs are naturally loyal to their human caretakers, and humans instinctively learn to walk and to speak and understand language. Rabbits are naturally fearful, but some are more fearful than others; some dogs are more loyal than others to their caretakers; and some humans learn to speak and write better than others do. Personality is not determined by any single gene, but rather by the actions of many genes working together. Furthermore, even working together, genes are not so powerful that they can control or create our personality. Some genes tend to increase a given characteristic and others work to decrease that same characteristic—the complex relationship among the various genes, as well as a variety of random factors, produces the final outcome. Furthermore, genetic factors always work with environmental factors to create personality. Having a given pattern of genes doesn‘t necessarily mean that a particular trait will develop, because some traits might occur only in some environments. For example, a person may have a genetic variant that is known to increase his or her risk for developing emphysema from smoking. Studying Personality Using Behavioral Genetics Perhaps the most direct way to study the role of genetics in personality is to selectively breed animals for the trait of interest. In this approach the scientist chooses the animals that most strongly express the personality characteristics of interest and breeds these animals with each other. If the selective breeding creates offspring with even stronger traits, then we can assume that the trait has genetic origins. In this manner, scientists have studied the role of genetics in Attributed to Charles Stangor Saylor. Although selective breeding studies can be informative, they are clearly not useful for studying humans. For this psychologists rely onbehavioral genetics—a variety of research techniques that scientists use to learn about the genetic and environmental influences on human behavior by comparing the traits of biologically and nonbiologically related family members (Baker, [2] 2010). Behavioral genetics is based on the results of family studies, twin studies, and adoptive studies. A family study starts with one person who has a trait of interest—for instance, a developmental disorder such as autism—and examines the individual’s family tree to determine the extent to which other members of the family also have the trait. The presence of the trait in first-degree relatives (parents, siblings, and children) is compared to the prevalence of the trait in second- degree relatives (aunts, uncles, grandchildren, grandparents, and nephews or nieces) and in more distant family members. The scientists then analyze the patterns of the trait in the family members to see the extent to which it is shared by closer and more distant relatives. Although family studies can reveal whether a trait runs in a family, it cannot explain why. Twin studies rely on the fact that identical (or monozygotic) twins have essentially the same set of genes, while fraternal (or dizygotic) twins have, on average, a half-identical set. The idea is that if the twins are raised in the same household, then the twins will be influenced by their environments to an equal degree, and this influence will be pretty much equal for identical and fraternal twins. In other words, if environmental factors are the same, then the only factor that can make identical twins more similar than fraternal twins is their greater genetic similarity. In a twin study, the data from many pairs of twins are collected and the rates of similarity for identical and fraternal pairs are compared. A correlation coefficient is calculated that assesses Attributed to Charles Stangor Saylor. Twin studies divide the influence of nature and nurture into three parts: Heritability (i. Shared environment determinants are indicated when the correlation coefficients for identical and fraternal twins are greater than zero and also very similar. These correlations indicate that both twins are having experiences in the family that make them alike. Nonshared environment is indicated when identical twins do not have similar traits. These influences refer to experiences that are not accounted for either by heritability or by shared environmental factors.
