Effects of prenatal cocaine and genotype on intermale agonistic behavior in Mus musculus

We exposed the pups of three F₁ genotypes of mice to a daily regime of cocaine by injecting their mothers (all C57BL/10J strain) on days 7–18 of gestation with 20 mg/kg subcutaneously. Pups of the cocaine and control groups did not differ on measures of maternal and pup health or size. Male pups were weaned and isolated at 21 days of age and their behaviors measured in an intermale aggression situation at about 80 days of age. Treated and untreated males of each F₁ genotype were paired in dyads with either a C3H/HeJ (hawk-like) or AKR/J (retaliator-like) standard tester male. Standard tester males were not exposed to cocaine. Cocaine treatment alone reduced the overall level of aggression in dyads, and in interaction with genotype or the standard tester it altered the behavior of dyads in all phases of social interaction: the initiation, content, and outcome. Standard testers used as behavioral probes, differentiated cocaine and control males with respect to their stimulus and behavioral qualities. Aggr.

The Tri-Council Policy Statement and Research in Cyberspace: Research Ethics, the Internet, and Revising a ‘Living Document’

Increasingly, the Internet is proving to be an important research tool. Today, cyberspace affords researchers easy access to traditionally difficult to reach populations, a host of virtual communities, and a wealth of data created through computer-mediated-communication. This newfound research frontier brings with it, however, a multiplicity of ethical concerns, including: (1) whether the Internet constitutes a private or public space; (2) whether the human subject paradigm is appropriate when considering the ethics of Internet research; and (3) whether cyber participants/‘speakers-as-writers’ and communities should be guaranteed confidentiality and anonymity when researchers contain or consider them in research. This paper examines these specific ethical concerns as they relate to Canada's Tri-Council Policy Statement: Ethical Conduct for Research Involving Humans, which, as yet, does not explicitly address ethics involved in Internet research. I propose that in large part the Internet is by definition a public site of activity, and as such, many posters cannot expect their texts to remain confidential, nor their names anonymous, and that the human subject paradigm is highly problematic in terms of regulating ethics involved in some research generated through new information technologies. This is most expressly the case with computer-mediated-communication, which, in light of the Tri-Council Policy Statement, can be viewed as theoretically akin to public entertainment and performance.

The Discipline and Habit of Theological Reflection

This article describes the process of theological reflection and the necessity of its practice in the formation of pastoral identity and development of ministry. Drawing upon the philosophy of C.S. Peirce, pastoral theology of the past twenty-five years, and the authors' clinical and classroom experiences, the essay illuminates the distinctive work of pastoral care givers that makes them unique in health care settings.     

Tokens, Dates And Tenseless Truth Conditions

There are two extant versions of the new tenseless theory of time: the date versionand the token-reflexive version. I ask whether they are equivalent, and if not, whichof them is to be preferred. I argue that they are not equivalent, that the date version isunsatisfactory, and that the token-reflexive version is correct. I defend the token-reflexive version against a string of objections from Quentin Smith. My defence involves a discussion of the ontological and semantic significance of truth conditions, and of the connection between truth and reality on the one hand, and that between truth and meaning on the other. I argue that Smith's objections to the token-reflexive theory stem from his confusing these two aspects of the notion of truth.     

Gender Differences in Anticipated Salary: Role of Salary Estimates for Others,Job Characteristics,Career Paths,and Job Inputs

The purpose of this research was to compare pay expectations of women and men. Participants were 371 college students (261 women, 110 men; 94% White) from a variety of majors. Most students at this university are middle class. Consistent with prior research, women estimated significantly lower salaries at career entry and peak and rated family considerations and pleasant working conditions as significantly more important than did men. Men and women differed on salary estimates for others, influence of salary on decision to enter a field, time off for childrearing, career certainty, and weekly work hours. Controlling for average salaries in the listed job, job characteristic importance, career path, and job input differences eliminated the gender differences at entry and reduced the difference at peak.

Reproducing the Motherboard: The Invisible Labor of Discourses that Gender Digital Fields

Within the digital workforce, women are disappearing. While there are many factors that could be ‘blamed’ for this phenomenon, this article takes issue with the sexist and patriarchal discourses that are deployed within the digital workforce. In many ways, sexist discourses are taken for granted within the digital workplace; and in that way, the discourses themselves are rendered invisible through a lack of concerted uncovering of the ways that these sexist discourses produce—and reproduce—women as sexual objects and outsiders in this field of work. The sexist and patriarchal discourses I address in this article validate the gender binary even as there is gendered play. It is this ‘play’ that also makes counter-hegemonic discourse and discursive acts productive (and reproductive), as I argue toward the end of the paper. Schools are a place where counter-hegemonic discourses and acts can be nurtured and, hopefully, affect and counteract the disappearance of women in digital fields.     

Why does working memory span predict complex cognition? Testing the strategy affordance hypothesis

We introduce and empirically evaluate the strategy affordance hypothesis, which holds that individual differences in strategy use will mediate the relationship between performances on a working memory (WM) span task and another cognitive task only when the same strategies are afforded by both tasks. One hundred forty-eight participants completed basic memory tasks and verbal span tasks that afford the same strategies, such as imagery and sentence generation, and completed reading comprehension tasks that afford different ones, such as self-questioning and summarization. Effective strategy use on WM span tasks accounted for variance in the span-memory relationship, but not for the span-comprehension relationship, supporting the strategy affordance hypothesis. Strategy use mediated the span-cognition relationship only when both tasks afforded the same strategies.     

Gender Differences in Aggression: The Role of Status and Personality in Competitive Interactions

Southwest US undergraduates (78 female, 72 male) were tested in a laboratory aggressive behavior paradigm involving noise blasts participants could use against another (bogus) same-sex competitor in a point-earning task. Status of the competitor (low vs. high) and expectation to meet the competitor (meet vs. no meet) were experimentally manipulated. A significant gender × aggression proneness × status interaction indicated that aggression-prone men were more likely to aggress against a high status competitor, while aggression-prone women were more likely to aggress against a low status competitor. Interactions of narcissism and sensation seeking with gender and anticipated meeting indicated that men but not women high in these personality traits were more likely to aggress, but only towards competitors they anticipated meeting.
