    Abstract: The present studies address two criticisms of the theory of evolved sex differences in jealousy: (a) that the sex difference in jealousy emerges only in response to hypothetical infidelity scenarios, and (b) that the sex difference emerges only using forced-choice measures. In two separate studies, one a paper-and-pencil survey with a student sample and the other a web-based survey targeting a non-student sample, men and women showed significant sex differences in jealousy in response to actual infidelity experiences; men experienced more jealousy in response to the sexual aspects of an actual infidelity, whereas women experienced more jealousy in response to the emotional aspects of the infidelity. Sex differences emerged using both continuous measures of jealousy as well as the traditional forced-choice measure. Overall, our results demonstrate that sex differences in jealousy are not limited to responses to hypothetical infidelity scenarios; they also emerge in response to actual infidelity experiences.

    A time-domain reflectometry method for automated measurement of crack propagation in composites during mode I DCB testing under cold, hot, and hot/wet conditions

    Abstract: This article describes an automated method for the measurement of crack initiation and propagation in composite materials during modeI double cantilever beam (DCB) testing under different environmental conditions. The method uses the time-domain reflectometry (TDR)-DCB system, which transmits a high-frequency pulse through a transmission line integrated within the composite test coupon and measures impedance discontinuities generated due to the presence of a crack. Using this system, real-time crack propagation in the specimen can be monitored, and the critical fracture toughness parameters ( G IC ) can be calculated in a variety of environmental conditions. TDR-DCB test method was used for the measurement of G IC for dry and wet (water-saturated) DCB samples made from E-glass fiber/vinyl ester composites under dry conditions (room temperature (RT) at 94°C) and wet conditions (RT at 60°C). For all test conditions, TDR signals showed that crack initiation and propagation was the dominant mechanism in identifying impedance changes in the material. Changes in dielectric properties of the specimen due to the test conditions, whether from water uptake, temperature, or a combination of the two, did not significantly affect signal quality.

    Male Sexual Jealousy: Lost Paternity Opportunities?
    SAGE Publications ; 2019

    Abstract: Numerous studies have shown that men experience relatively greater levels of jealousy in response to the sexual aspects of an infidelity (relative to women), whereas women experience relatively greater levels of jealousy in response to the emotional aspects of an infidelity (relative to men). The traditional explanation for this relationship suggests that men experience this greater level of jealousy due to threats of a loss of paternal certainty. In this article, we present three studies that demonstrate that men’s differentially greater jealousy occurs in response to situations that threaten paternity opportunities. These results suggest that a loss of perceived paternity opportunities is the ultimate origin of men’s increased jealousy in response to sexual infidelity.

    Enhancing Textile Fiber Identification with Detergent Fluorescence

    Abstract: Discovering common origins of trace evidential textile fibers can be a challenging task when fiber structure or dye composition does not provide exclusive identifying information. Introduction of new chemical species after mass production and distribution of a textile may be exploited to trace its history and identify the origin of its fibers. In this article, fluorescence microscopy is used to examine the alteration in the fluorescence spectral fingerprint of single fibers resulting from exposure to commonly used detergents that contain fluorescent whitening agents. Dyed acrylic, cotton, and nylon fibers were laundered and the spectral contribution of the detergent on single fibers was quantified and shown to reach a maximum after five sequential washes; some detergents showed statistically meaningful differences to fiber spectra after only a single wash. Principal component cluster analysis was used to determine that the spectra of laundered fibers are distinct from the spectra of dyed, unwashed cotton or nylon, but not acrylic, fibers.

    Process and Performance Evaluation of the Vacuum-Assisted Process

    Abstract: Vacuum-Assisted Resin Transfer Molding (VARTM) is widely used for large-scale composite manufacturing of civil and defense applications. Here, the infusion process reduces part costs due to a decrease in labor, material, and equipment expenses compared to other composite manufacturing techniques. However, in order to replace conventional manufacturing methods for aerospace-quality parts such as autoclave processing, the VARTM process repeatability and part quality must be improved. The Vacuum-Assisted Process (VAP) (Filsinger, J., Lorenz, T., Stadler, F. and Utecht, S. (2001). Method and Device for Producing Fiber-reinforced Components Using an Injection Method, German Patent WO 01/68353 A1.) developed and patented by EADS Deutschland uses a gas-permeable membrane to allow for uniform vacuum distribution and continuing degassing of the infused resin.W.L. Gore & Assoc. GmbH has developed a suitable membrane in co-operation with EADS. The membrane is placed over the fabric layers, sealed to the tool, and connected to the vent to allow uniform vacuum on the fabric surface. The VAP results in a more robust VARTM process that minimizes the potential for dry spot formation as well as lower void content and improved dimensional tolerances. This research quantifies the performance improvements and compares them to the Seemann Composite Resin Infusion Process (Seemann, William (1991). Plastic Transfer Molding Apparatus for the Production of Fiber Reinforced Plastic Structures, U.S. Patent, 5,052,906) (SCRIMP), the most common variation of the VARTM process.
