The Genetic, Social, & Behavioral Factors That Motivate Parents to Abuse their Children

This paper examines the influence of economic, genetic, behavioral, and social factors on the parental choice to abuse one’s child. I derive a choice model for the parents based on McFadden’s (1974) conditional logit model. Within society, the parent or parents not only bear the responsibility for their child’s well being, but also for ensuring the child will grow up to be an educated, productive member of society. Through the examination of individual parent and child behavior patterns, as well as numerous social and economic factors from the Physical Violence in American Families Survey of 1985, I show that after a child behaves in a certain manner, the parent chooses to abuse based on numerous social, economic, and genetic variables. Child abuse is a social problem that has not been examined heavily in the field of economics, but with the help of econometric analysis I examine how behavior and social trends can increase the probability of child abuse. Hopefully this analysis will lead to suggestions on how to remedy this problem. [excerpt

NSFW: An Empirical Study of Scandalous Trademarks

This project is an empirical analysis of trademarks that have received rejections based on their “scandalous” nature. It is the first of its kind. The Lanham Act bars registration for trademarks that are “scandalous” and “immoral.” While much has been written on the morality provisions in the Lanham Act, this piece is the first scholarly project that engages an empirical analysis of the Section 2(a) rejections based on scandalousness; it contains a look behind the scenes at how the morality provisions are applied throughout the trademark registration process. This study analyzes which marks are being rejected, what evidence is being used to reject them, and who the applicants are. Our data pays particularly close attention to the evidence used to determine whether a mark is scandalous. We also consider whether this bar is effective at removing these marks from the consumer marketplace

Autonomic arousal and attentional orienting to visual threat are predicted by awareness

The rapid detection and evaluation of threat is of fundamental importance for survival. Theories suggest that this evolutionary pressure has driven functional adaptations in a specialized visual pathway that evaluates threat independently of conscious awareness. This is supported by evidence that threat-relevant stimuli rendered invisible by backward masking can induce physiological fear responses and modulate spatial attention. The validity of these findings has since been questioned by research using stringent, objective measures of awareness. Here, we use a modified continuous flash suppression paradigm to ask whether threatening images induce adaptive changes in autonomic arousal, attention, or perception when presented outside of awareness. In trials where stimuli broke suppression to become visible, threatening stimuli induced a significantly larger skin conductance response than nonthreatening stimuli and attracted spatial attention over scrambled images. However, these effects were eliminated in trials where observers were unaware of the stimuli. In addition, concurrent behavioral data provided no evidence that threatening images gained prioritized access to awareness. Taken together, our data suggest that the evaluation and spatial detection of visual threat are predicted by awareness

Fearful faces have a sensory advantage in the competition for awareness

Only a subset of visual signals give rise to a conscious percept. Threat signals, such as fearful faces, are particularly salient to human vision. Research suggests that fearful faces are evaluated without awareness and preferentially promoted to conscious perception. This agrees with evolutionary theories that posit a dedicated pathway specialized in processing threat-relevant signals. We propose an alternative explanation for this "fear advantage." Using psychophysical data from continuous flash suppression (CFS) and masking experiments, we demonstrate that awareness of facial expressions is predicted by effective contrast: the relationship between their Fourier spectrum and the contrast sensitivity function. Fearful faces have higher effective contrast than neutral expressions and this, not threat content, predicts their enhanced access to awareness. Importantly, our findings do not support the existence of a specialized mechanism that promotes threatening stimuli to awareness. Rather, our data suggest that evolutionary or learned adaptations have molded the fearful expression to exploit our general-purpose sensory mechanisms

Health evaluation of free-ranging and captive pichis (Zaedyus Pichiy; Mammalia, Dasypodidae), in Mendoza province, Argentina

The health of free-ranging and captive pichis (Zaedyus pichiy) was assessed in Mendoza Province, Argentina, between November 2001 and December 2006. Postmortem examinations of 150 confiscated and vehicle-killed pichis and clinical examinations of 139 wild-caught individuals suggest that the wild populations are currently in good health. Lesions and scars were observed in a large proportion of wild-caught pichis. The most common lesions were associated with parasitism or parasite larva migration. Sarcocystis cysts were relatively common in the skeletal muscle, and Besnoitia cysts were observed in the lungs of 24 evaluated animals. Elevated ambient humidity levels often caused moist dermatitis with epidermal detachment in captive pichis. This report constitutes the first health evaluation of free-ranging and captive Z. pichiy. It will be a starting point for future health studies and will be beneficial for the captive management of this species.Fil: Superina, Mariella. University Of New Orleans; Estados Unidos.

Narrative Analysis of Sexual Etiquette in Teenage Magazines

Expanding on existing research on women\u27s magazines, this essay examines the sexual etiquette developed in advice columns in magazines popular among teenage women. Over a span of 20 years, the advice has changed very little. Serving the rhetorical function of field guides and training manuals, teen magazines limit women\u27s sociality and sexuality within narrowly defined heterosexual norms and practices. The rhetoric of sexual etiquette encourages young women to be sex objects and teachers of interpersonal communication rather than lovers, friends, and partners. Young women are being taught to subordinate self for others and to be contained

The microstructure and microtexture of zirconium oxide films studied by transmission electron backscatter diffraction and automated crystal orientation mapping with transmission electron microscopy

A detailed characterization of nanostructured thin zirconium oxide films formed during aqueous corrosion of a nuclear-grade zirconium alloy (Zircaloy-4) has been carried out by means of two novel, ultra-high-spatial-resolution grain mapping techniques, namely automated crystal orientation mapping in the transmission electron microscope (TEM) and transmission electron backscatter diffraction (t-EBSD). While the former provided excellent spatial resolution with the ability to identify tetragonal ZrO<sub>2</sub> grains as small as ∼5 nm, the superior angular resolution and unambiguous indexing with t-EBSD enabled verification of the TEM observations. Both techniques revealed that in a stress-free condition (TEM foil prepared by focused ion beam milling), the oxide consists mainly of well-oriented columnar monoclinic grains with a high fraction of transformation twin boundaries, which indicates that the transformation from tetragonal to monoclinic ZrO<sub>2</sub> is a continuous process, and that a significant fraction of the columnar grains transformed from stress-stabilized tetragonal grains with (0 0 1) planes parallel to the metal–oxide interface. The TEM analysis also revealed a small fraction of size-stabilized, equiaxed tetragonal grains throughout the oxide. Those grains were found to show significant misalignment from the expected (0 0 1) growth direction, which explains the limited growth of those grains. The observations are discussed in the context of providing new insights into corrosion mechanisms of zirconium alloys, which is of particular importance for improving service life of fuel assemblies used in water-cooled reactors

Utilization of BIOSCREEN to Calculate Retardation Factor of Petroleum Contaminants, and Biodegradation Rate for a Site in Montpelier, Indiana

In March 1994, a report was issued to the Indiana Department of Environmental Management after Jim Allen Maintenance, Inc. found levels of total petroleum hydrocarbons (TPH) exceeding the level appropriate for action (100 parts per million) during an underground storage tank closure report assessment. Creek Run L.L.C Environmental Engineering was contracted by Jay Petroleum to complete an initial site characterization. Through quarterly monitoring of benzene, toluene, ethyl benzene, and methyl tert-butyl ether for 11 years, Creek Run L.L.C determined that biodegradation was occurring. Upon using BIOSCREEN, a contaminant transport modeling software that simulates natural attenuation over time, it was determined that the retardation factor was 1.4, and the biodegradation rate constant was 4.6 per year. This indicates that the contaminant migration is slow in comparison to groundwater flow, and the rate of biodegradation is at an appropriate value to allow natural attenuation to occur on its own
