A general approach to determination of age follows: Fetal period: Estimation of fetal developmental age assumes forensic importance in most jurisdictions because it is usually an indicator of viability buy generic actonel 35mg. In instances of criminal death of a pregnant individual courts may decide whether to prosecute more than one homicide depending upon the age (i buy actonel 35mg on line. Knowing the age of a discovered fetus may also assist in matters of identifca- tion discount 35 mg actonel with mastercard. Usually, diaphyseal lengths may be used in various algorithms to estimate crown–rump length, which may then be translated into lunar age. Te timing of appearance of primary and some secondary ossifcation centers is also of use. Several sources give good accounts of the statistical reliability of various bones and measurements for both gross and radiographic fetal age determination. As noted, dental and osteological age should correlate well within this develop- mental interval. In recent years anthropologists and odontologists have become increasingly aware of diferences in rates of skeletal and dental maturation among various populations,34 and have begun to apply adjustments to their age estimates accordingly. Sixteen to thirty years: As attachment of primary and secondary ossif- cation centers occurs throughout the skeleton, attention turns to the completion of fusion of these centers. Numerous investigators have Forensic anthropology 145 established rating scales that describe the degree to which growth cartilages (metaphyses) have been replaced by bone, signaling the completion of that skeletal element or an articulation. Tese techniques usually take the form of a semantic diferen- tial, which describes changes in the appearance characteristics of a particular structure at known points in time based upon controls. Tirty years and beyond: As the last epiphyses (usually the medial clavicles) complete development, skeletal age may still be estimated, albeit with increasing error. As a result of endocrine-driven cellular interactions that constantly remove bone and replace it, the skeleton continues to “turn over” approximately every seven to ten years, remodeling itself to accommodate gravity and the mechani- cal habits of its owner. Alongside this process, the skeletal cartilages that separate and cushion bones undergo increased hardening with resulting grossly observable wear at the articulations, i. Age-related changes in the weight-bearing joints (ankle, knee, hip, sacroiliac, spine, etc. For example, as the marrow of long bones assumes a larger part of the hemopoetic burden with age, one can observe an advance of the apex of the marrow cavities in femora and humeri. As old cortical bone is scavenged by osteoclasts to maintain mineral homeostasis, new vascular pathways import osteoblasts that replace it. As the skeleton moves through time, the amount of unremodeled lamellar bone seen 146 Forensic dentistry in microscopic cross sections of cortex will diminish, and the num- ber of partly replaced structural units of old bone, osteon fragments, will increase. Tese changes have been documented and calibrated by various authors for a number of sites in the skeleton,43–45 and are of use in the aging skeleton because the process of turnover on which it is based extends throughout life. As is the case with other techniques, error in the calculated age range by histomorphological methods increases with time. Since the estimated stature derives from long bone lengths that do not change signifcantly afer matu- rity, this approach gives a range that does not take into consideration loss of stature from compression of the spinal fbrocartilages. A correction is usu- ally applied for individuals whose age is estimated to be over thirty years. When long bones are incomplete because of trauma or taphonomic efects, it is sometimes possible to estimate the vital length of some bones by proportionality techniques. In general, the best estimates of stature are based upon multiple bones, which are used in algorithms derived from population data refecting current secular trends. Anthropologists are sometimes asked to render estimates of the living weight of a decedent who has been reduced to bones. Putting aside ancillary information such as belts, shoes, and other clothing that may accompany remains, the answer will require strong qualifcation. Since an individual may lose as much as 50% of his or her body mass over a relatively short time (e. Accordingly, statements about frame size, proportionality, and the distribu- tion of muscularity are preferable. Cross-sectional thickness or simply the weight of various bones in combination with proportionality ratios can pro- vide information about how much sof tissue weight an individual might be expected to carry. Tis picture may be refned by a careful examination of entheses, the points of tendon insertion, which are modifed by muscular activity over a period of time. Tus, one may arrive at an estimate of how Forensic anthropology 147 well developed an individual may have been for a particular frame size and stature at some point in life. Examination of the pattern in which the skeleton has reinforced itself in response to habitual or repetitive biomechanical action has sometimes proved useful in the inclusion or exclusion of certain occupations, sports, or other activities performed over a period of several years, which may alter a list of suspected matches. When these data, combined with a list of unique identifers, are compared to a database of missing persons, the list of possible matches usually reduces to a manageable few. At the discovery of unknown human remains, the authorities will either have a theory about the identity of the decedent or not. Tis will include dental charts, bitewings and pano- graphic images if available, old x-rays, or other medical images (e. When images are unavailable, medical records describing pros- theses, pacemakers, shunt devices, cosmetic implants, orthopedic devices, and the like may be sufciently detailed for comparison to the postmortem evidence. Antemortem records of diseases that would be expected to leave evi- dence in the hard tissues are also useful, particularly when the incidence of a disorder is known. In some cases of suspected identity, when none of the foregoing is available, it is sometimes useful to perform a skull-to-photograph superimposition. Although tradition- ally used to exclude matches, some have successfully employed video super- imposition to achieve positive identifcations when a complete skull and good quality photographs from several angles are available.

Culture-fair testing is a timely issue given current Mensh, Elaine, and Harry Mensh. His father was a successful provincial physician, and his grandfather, Erasmus Darwin (1731-1802), had been a distinguished intellectual figure. Young Darwin attended the Shrewsbury School, and his early failure to achieve academic distinction continued at Edinburgh University, where he studied medicine, and at Cambridge University, where he studied theology. While at Cambridge, however, Darwin enthusiastically pursued natural history as an avo- cation, drawing the attention of botanist John Stevens Henslow (1796-1861) and geologist Adam Sedgwick (1785-1873). In 1831, through his connection with Henslow, Darwin joined the expedition team aboard the survey ship H. Beagle headed for the coasts of South America, the Galápagos Islands, New Zealand, and Tas- mania. There is some indication that Darwin went on the voyage in order to accompany Captain FitzRoy. FitzRoy, as captain, was not to socialize with the lower status crew members on the ship, and he was worried about maintain- ing his mental health during the long, solitary voyage. Upon his return to England, Darwin de- principles hold that in the struggle for existence, some veloped his theory of evolution, one of the major intellec- individuals, because of advantageous biological adap- tual achievements of the nineteenth century. However, be- tation,are better able to occupy effectively a given eco- cause of his creationist perspective, some of the observa- logical niche and therefore will produce more offspring tions made during the voyage were not useful in the devel- than individuals who are less able.

In ilarities and differences between human and animal The Descent of Man (1871), he supported the contro- psychological functioning. In addition, Darwin’s prin- versial position that human beings are descended from ciple of natural selection led to a greater interest in animal ancestors. In line with this idea, he argued that variation and individual differences among members the mental activities of humans and animals are funda- of the same species. He identified the presence in animals of “human” qualities such as courage and devotion, and Darwin’s other books include The Variations of Ani- “human” emotions, including pride, jealousy, and mals and Plants under Domestication (1868), Insectivo- shame.

Long-term Goal Client will participate in interactions with others at level of abil- ity or desire. Be with the client to offer support during activities that may be frightening or difﬁcult for him or her. Most individuals keep the same style of relationship development that they had in the past. Help the client identify present relationships that are satisfying and activities that he or she considers interesting. Only the cli- ent knows what he or she truly likes, and these personal pref- erences will facilitate success in reversing social isolation. Risk Factors Caregiver not developmentally ready for caregiver role Inadequate physical environment for providing care Unpredictable illness course or instability in the care receiver’s health Psychological or cognitive problems in care receiver Presence of abuse or violence Past history of poor relationship between caregiver and care receiver Marginal caregiver’s coping patterns Lack of respite and recreation for caregiver Addiction or codependency Caregiver’s competing role commitments Illness severity of the care receiver Duration of caregiving required Family/caregiver isolation Goals/Objectives Short-term Goal Caregivers will verbalize understanding of ways to facilitate the caregiver role. Long-term Goal Caregivers will demonstrate effective problem-solving skills and develop adaptive coping mechanisms to regain equilibrium. Ensure that caregivers are aware of available community sup- port systems from which they can seek assistance when re- quired. Examples include respite care services, day treatment centers, and adult day-care centers. Caregivers require relief from the pressures and strain of providing 24-hour care for their loved one. Studies have shown that abuse arises out of caregiving situations that place overwhelming stress on the caregivers. Release of these emotions can serve to prevent psychopathol- ogy, such as depression or psychophysiological disorders, from occurring. Encourage participation in support groups composed of members with similar life situations. American Association on Intellectual and Developmental Disabilities—(800) 424-3688 c. Alzheimer’s Association—(800) 272-3900 Hearing others who are experiencing the same problems discuss ways in which they have coped may help the caregiver adopt more adaptive strategies. Individuals who are experi- encing similar life situations provide empathy and support for each other. Caregivers demonstrate adaptive coping strategies for deal- ing with stress of caregiver role. Bellﬁeld and Catalano (2009) have stated: Forensic nursing is an emerging ﬁeld that forms an alliance between nursing, law enforcement, and the forensic sciences. Forensic nurses provide a continuum of care to victims and their families beginning in the emergency room or crime scene and lead- ing to participation in the criminal investigation and the courts of law (p. Nurses in general practice Clinical Forensic Nursing in Trauma Care Assessment Lynch, Roach, and Sadler (2006) have stated, “Forensic nurse specialists are speciﬁcally trained to deal with cases of sexual assault, child abuse, acute psychiatric emergencies, and death investigation” (p. All traumatic injuries in which liability is suspected are considered within the scope of forensic nurs- ing. Reports to legal agencies are required to ensure follow-up investigation; however, the protection of clients’ rights remains a nursing priority. Several areas of assessment in which the clinical forensic nurse specialist in trauma care may become involved include: 1. Evidence from both crime- related and self-inﬂicted traumas must be safeguarded in a 358 Forensic Nursing ● 359 manner consistent with the investigation. Evidence such as clothing, bullets, bloodstains, hairs, ﬁbers, and small pieces of material such as fragments of metal, glass, paint, and wood should be saved and documented in all medical accident in- stances that have legal implications. Sharp-Force Injuries: Sharp-force injuries including stab wounds and other wounds resulting from penetration with a sharp object. Blunt-Force Injuries: Includes cuts and bruises resulting from the impact of a blunt object against the body. Dicing Injuries: Multiple, minute cuts and abrasions caused by contact with shattered glass (e. Patterned Injuries: Speciﬁc injuries that reﬂect the pattern of the weapon used to inﬂict the injury. Defense Wounds: Injuries that reﬂect the victim’s attempt to defend himself or herself from attack. Hesitation Wounds: Usually superﬁcial, sharp-force wounds; often found perpendicular to the lower part of the body and may reﬂect self-inﬂicted wounds. Fast-Force Injuries: Usually gunshot wounds; may reﬂect various patterns of injury. When deaths oc- cur in the emergency department as a result of abuse or acci- dent, evidence must be retained, the death must be reported to legal authorities, and an investigation is conducted. It is therefore essential that the nurse carefully document the appearance, condition, and behavior of the victim upon ar- rival at the hospital.
