Distributions of genetic markers in United States populations: III. Serum group systems and hemoglobin variants

All published and unpublished population frequency data that could be located for U.S. populations are tabulated and presented for the serum group systems haptoglobin (alpha-chain), group specific component, and transferrin and for the common beta-chain variants of hemoglobin. Results obtained by combining data for comparable racial/ethnic groups are also presented. Some evidence is presented to indicate that the results obtained from the combined data may give better information on frequencies for the U.S. population at large than is obtainable from studies conducted in restricted geographic areas.

Paired stable carbon and oxygen isotope analyses of human enamel for forensic human geolocation: An exploratory study

Stable carbon isotope analysis has proven utility for reconstructing dietary information in humans in past populations. The usefulness of stable carbon for forensic geolocation has been little investigated, largely because of the globalization of the human diet seemingly rendering it inconsequential. This study queried this assumption at a country-wide level on a known sample group. Stable carbon isotope values were obtained from human enamel with known biographical and geographical information to determine whether stable carbon, when paired with stable oxygen isotope values, could differentiate Canadians from non-Canadians. Samples originating outside of Canada were separated into three regions, and a linear discriminant analysis was used to generate discriminant functions that best separate the regions according to the stable carbon and oxygen isotope values. The results revealed two functions, where the first function explained 92.1% and the second 7.9% of the variance. Although some overlap in stable carbon and oxygen values was observed for individuals from both the United States and Canada, differences were observed between those from Canada and other geographical regions. This study demonstrated that pairing the dietary isotope carbon with the geolocator stable oxygen isotope, produced an interesting separation geographically, one that might well be helpful when attempting a geolocation query on unknown human remains.     

Confidence in the police: Balancing public image with community safety – A comparative review of the literature

Examining the evolution of British and Australian policing, this comparative review of the literature considers the historical underpinnings of policing in these two countries and the impact of community legitimacy derived from the early concepts of policing by consent. Using the August 2011 disorder in Britain as a lens, this paper considers whether, in striving to maintain community confidence, undue emphasis is placed on the police's public image at the expense of community safety. Examining the path of policing reform, the impact of bureaucracy on policing and the evolving debate surrounding police performance, this review suggests that, while largely delivering on the ideal of an ethical and strong police force, a preoccupation with self-image may in fact result in tarnishing the very thing British and Australian police forces strive to achieve – their standing with the public. This paper advocates for a more realistic goal of gaining public respect rather than affection in order to achieve the difficult balance between maintaining trust and respect as an approachable, ethical entity providing firm, confident policing in this ever-evolving, modern society.     

Reactions to participating in dating violence research: are our questions distressing participants?

In recent years, there has been increased research focus on dating violence, producing important information for reducing these violent relationships. Yet Institutional Review Boards (IRBs) are often hesitant to approve research on dating violence, citing emotional distress of participants as a possible risk of participation. However, no known research has examined the reactions of research participants to questions about dating violence. The current study examined the reactions among college students to completing a self-report measure on dating violence. Results showed that participants reported numerous positive experiences as a result of their research participation, with only mildly increased negative emotional reactions evident for some. Findings are discussed in relation to IRB proposals and appropriate informed consent for research participants.     

Impelling and inhibitory forces in aggression: sex-of-target and relationship effects

The finding of symmetry in intimate partner aggression is now generally accepted, but the convergence of male and female rates in these relationships remains unexplained. From qualitative analysis of male and female focus group discussions, we identified factors believed to influence the expression of aggression toward targets differing in sex and degree of intimacy. These factors were then used to construct a questionnaire in which 355 respondents indicated the applicability of the items to conflicts with a partner, a same-sex friend, and an opposite-sex friend. Principal component analysis revealed a clear two-factor structure of impelling forces (tending to provoke or initiate aggression) and inhibitory forces (tending to suppress or diminish the likelihood of aggression). Participants' scores on scales derived from these two factors were used in the subsequent analyses. Men reported lower inhibition and greater impulsion toward same-sex friends than to female friends and partners, who did not differ significantly from one another. Women showed lower inhibition to male targets, regardless of relationship, than to a female target. However, women rated their male partners as significantly higher on impelling forces than their male friends, who in turn were rated significantly higher than female friends. The results are broadly consistent with a sex-of-target effect corresponding to a chivalry norm held by both sexes that inhibits the expression of aggression toward women. The reasons why women are especially impelled to aggression by intimate partners are explored. Disaggregating the dynamics of interpersonal conflict into impelling and inhibitory components may prove useful in understanding and treating dispute escalation and resolution.
