    A new cryptic Sympistis from eastern North America revealed by novel larval phenotype and host plant association (Lepidoptera, Noctuidae, Oncocnemidinae)

    A Triosteum-feeding species of Sympistis is described from eastern North America: Sympistis forbesi sp. n. Identity of the new species is most reliably determined from larval morphology and host plant association—both adult scaling and genitalic characters overlap with those of Sympisitis chionanthi, a Chionanthus and Fraxinus feeder

    Measuring equity in intimate relations

    No full text
    It has been suggested that equity theory, a social psychological theory concerned with the fairness in casual relationships, should be applicable to intimate relations as well. As a first step in that direction, this report describes the development of the Traupmann-Utne-Walster Equity/Inequity Scales, which measure the level of equity that intimate couples perceive in their relationships. The scales, which include items from four areas of concern for intimates-personal concerns, emotional concerns, day-to-day concerns, and opportunities gained or lost-are described, and data from two empirical studies are reported. The first study demonstrates the internal consistency reliability of the scales. The second study reports data relevant to the construct validity of the scales. Two constructs derived from equity theory-affect and satisfaction-shown to behave in the predicted way when the Traupmann- Utne-Walster Scales are used as the measure of inequity

    The Endurance of Love: Passionate and Companionate Love in Newlywed and Long-Term Marriages

    Most theorists assume that the passage of time will have a very different impact on passionate versus companionate love.  Passionate love is said to decline fairly quickly, while companionate love is thought to remain fairly stable (or actually increase) over time.  This hypothesis was tested in two studies.  In Study 1, we interviewed 53 newlywed couples soon after their marriages and again one year later, when presumably (for some) the “honeymoon was over.”  In Study 2, we interviewed a random sample of 240 older women, ranging in age from 50-82, who had been married varying lengths of time.  (The median length of marriage was 33 years.)  We asked about their passionate and companionate love for their partners and their partner’s love for them.   In Study 1, it was found that although newlywed men and women loved with equal passion, women tended to love their partners more companionately than they were loved in return.  (This is in accord with previous research with dating couples.)  The results for people married many years were more complex. Finally, we turned to the question with which we are most concerned: What impact does time have on love?  In both Study 1 and Study 2, time did have a corrosive effect on love—but to our surprise it appeared to have an equally detrimental effect on both passionate and companionate love

    Cryptic or underworked? Taxonomic revision of the Antistrophus rufus species complex (Cynipoidea, Aulacideini)

    Cryptic species present challenges across many subdisciplines of biology. Not all “cryptic” species, however, are truly cryptic; many are simply underexplored morphologically. We examined this idea for the Antistrophus rufus species complex, which previously contained three species thought to be morphologically cryptic. To determine whether the A. rufus complex are truly cryptic species, we assessed species boundaries of members of the A. rufus species complex using morphological, ecological, and DNA barcode data, and tested whether a set of 50 morphological characters could adequately diagnose these species. We revealed that this complex includes five species, and that there are useful phenotypic diagnostic characters for all members of this species complex. This enabled redescription of four species and the description of Antistrophus laurenae Nastasi, sp. nov., which induces externally inconspicuous galls in stems of Silphium integrifolium Michx., a host not associated with other members of the complex. We use these new diagnostic characters to construct a key to the five species of the rufus complex. We conclude that the A. rufus complex was not a true case of cryptic species. Our Bayesian analysis of DNA barcode data suggests possible cospeciation of members of the rufus complex and their Silphium host plants, but further study is necessary to better understand the evolution of host use in the lineage

    A Country of their Own: Women and Peacebuilding

    No full text
    Research on women and post-conflict reconstruction tends to focus primarily on women as victims and passive targets for aid rather than conceptualizing peacebuilding as a process where greater participation by women may help increase the prospects for success. Here, I argue that women’s social status is a dimension of social capital that is largely independent of general economic development. Societies and communities where women enjoy a relatively higher status have greater prospects for successful peacebuilding, as cooperation by the local population with peacebuilding policies and activities increases. Thus, in the presence of a UN-led peacebuilding operation, women’s status has a direct and independent impact on post-conflict reconstruction. The theoretical claims are empirically assessed by looking at variation in levels of cooperation and conflict during the UN peacebuilding missions within the countries of Sierra Leone and Liberia. </jats:p
