Musculoskeletal stress marker (MSM) differences in the modern American upper limb and pectoral girdle in relation to activity level and body mass index (BMI)

Obesity is a widespread condition affecting modern Americans. The prevalence of obesity has led to questions of how it can affect the skeleton, and if so can it be identified in unknown skeletal material. This study attempts to decipher the effects of activity level and body mass in modern Americans by employing musculoskeletal stress markers (MSM) to estimate osseous responses to workload and body weight. A total sample of 108 skeletons of known activity level and body mass index (BMI) was observed for MSM in the upper extremity (excluding hands). The entheses selected included arm muscles used during the sit-to-stand transition, which is common in most persons, regardless of activity level and BMI. Using the three categories: normal, active, and obese, logistic regression was calculated on MSM to ascertain which markers were the best indicators of these three categories. Numerous muscles of the upper limb were significant predictors of activity level and body mass, although they did not perform much better than chance. MSM may be used as predictors of activity level and/or BMI in forensic contexts; however, they should be used in conjunction with other indications of workload and/or BMI.     

The contour characteristics of the mucous membrane of the hard palate as dependent on the form of its osseous base]

Analyzes the relief of the hard palate mucosa, depending on the shape of osseous base. Presents data on the prevalence of various morphological shapes of lateral folds in the hard palate mucosa and the levels of their disposition in the ipsiloid, ellipsoid, and parabolic osseous base of the hard palate. Demonstrates the possibility of using the characteristics of the hard palatal mucosa relief as an extra test for personality identification by the oral status.     

Discriminant function analysis for sex assessment in pelvic girdle bones: sample from the contemporary Mexican population

Sex assessment of skeletal remains plays an important role in forensic anthropology. The pelvic bones are the most studied part of the postcranial skeleton for the assessment of sex. It is evident that a population-specific approach improves rates of accuracy within the group. The present study proposes a discriminant function method for the sex assessment of skeletal remains from a contemporary Mexican population. A total of 146 adult human pelvic bones (61 females and 85 males) from the skeletal series pertaining to the National Autonomous University of Mexico were evaluated. Twenty-four direct metrical parameters of coxal and sacral bones were measured and subsequently, sides and sex differences were evaluated, applying a stepwise discriminant function analysis. Coxal and sacra functions achieved accuracies of 99% and 87%, respectively. These analyses follow a population-specific approach; nevertheless, we consider that our results are applicable to any other Hispanic samples for purposes of forensic human identification.     

Parent-adolescent congruence on decision-making and its relation to adolescent adjustment

Much attention has been paid to the nature of parent-adolescent relationships, with a frequent conclusion being that it is a time of marked disagreement between parents and their adolescents. However, other literature suggests that this time is not inherently conflictual. The purpose of this study was to examine agreement and disagreement between mothers, fathers, and adolescents on specific issues. Then, adolescent adjustment was assessed, and the degree to which it was a function of congruence with parents was examined. A modified version of the Issues Checklist was used to measure intrafamily agreement; the Revised Behavior Problem Checklist and the Harter Scale of Child's Actual Competence were completed by adolescents' social studies teachers to assess adolescent functioning. Relative to their parents, adolescents reported that they should make more decisions alone, while both mothers and fathers reported that decisions should be made jointly among all family members. Only father-adolescent congruence was found consistently to be related to adolescent functioning. Possible explanations for the present results and relevant issues pertaining to family agreement are discussed.     

Crime patterns and their relation to subjective social stress and support indicators: The role of gender

This study investigated the relationship between the subjective perception of stress and support in the population (as independent variables) and the prevalence of homicide, robbery, and property offenses in society, while controlling for the effect of gender, i.e., how these crimes are related to the differential perception of stress and support among males and females. The theoretical framework is provided by a stress-support model which postulates that crime in society will be positively related to stress factors and negatively related to support systems. Eight stress indicators and four support (solidarity) indicators were included. The data regarding these indicators were derived from continuing surveys of representative samples of the urban population in Israel during the years 1967–1979. The theoretical model was supported by the findings, especially those relating to property offenses. The effects of the female indicators were strongest (and greater than those of males) with regard to property offenses. The regression coefficients of the female indicators were also consistently larger than those of males, indicating that women's perceptions of stress are better predictors of crime rates than those of males. The results are compared to those of previous studies and suggestions are made for future studies in this new line of criminological research.

Alcohol concentration and the ability to form intent

The ability to form intent to commit a particular act is often a significant issue in criminal litigation. Often, a complicating factor in the resolution of this issue is the presence of ethanol and drugs in the individual whose motives are to be ascertained. To determine whether an intoxicating blood ethanol concentration (BAC) in the absence of other information is sufficient to establish intent, we reviewed cases investigated by the Office of the Chief Medical Examiner, State of Maryland over a two-year period. Specifically, we identified cases of suicide with a suicide note, the presence of ethanol and the absence of other psychoactive drugs. The BACs ranged from 0.01 to 0.37 g/dL. The average BAC was 0.14 g/dL and the median BAC was 0.13 g/dL. Twenty-five of the 37 cases had a BAC greater than 0.08 g/dL. We conclude that a BAC alone is not sufficient to determine the capability of an individual to form intent to commit a particular act.

Postmortem examination of transepithelial ion currents in rabbit colon and trachea in relation to temperature of storage and its importance for interlethal reactions

Electrical phenomena resulting from transepithelial ion transport have been a subject of clinical, physiological, pharmacologic and toxicologic studies. These examinations concern mainly electric phenomena in live organisms. The changes of transepithelial ion pathways which take place postmortem have not been yet established. The aim of the study was an attempt to trace variability of electrophysiological parameters related to transepithelial ion transport in specimens of rabbit trachea and colon depending on temperature at which specimens were stored after death. It was observed that postmortem electric phenomena in epithelium of airways and alimentary tract of rabbit occur well-ordered but with slower course in trachea samples and in tissues which were preserved at low temperature after death.

Computer analysis of parentage in relation to maternity and paternity

General formulas for statistical calculations of parentage by means of blood group analysis are presented in relation to those of maternity and paternity. Based on these formulas, a computer program has been devised to calculate plausibilities, exclusion probabilities, and distributions of log (Y/X) of parentage for any blood groups. The program also gives numerical values of these quantities of maternity and paternity. The values of plausibility and exclusion probability are highest for parentage, and decrease in the order of paternity and maternity. Concerning the distribution of log (Y/X) for true families, a simple relation holds for the ratio of the mean value of log (Y/X) in parentage ap, to that in paternity af, and to that in maternity am as, ap: af: am = 1: 0.6: (0.6)2 This relation holds for all 14 blood groups examined.     

Postmodern criminology in relation to radical and conflict criminology

The literature on postmodern criminology suggests that there is some relationship between it and radical criminology. This relationship apparently is based in part on the ract that both are further related to conflict theory. However, conceptual analyses on these types of theories have not fully explicated whatever similarities and differences exist among them. This essay identifies six core theoretical assertions in conflict criminology and compares them to parallel assertions in radical and postmodern criminology. Such comparison is followed by a discussion on the relevance of conflict and radical theory as conceptual backdrops from which to comprehend postmodern inquiry.
