Palimpsest encounters: a baseline study of Federal, Antebellum, and Postbellum New Orleans gardens using the Notarial Archives drawings

The focus of this thesis is to establish a basis for a typology of New Orleans gardens from 19th Century Notarial drawings. Previous inquires of the New Orleans Notarial Archives drawings emphasized elite gardens of the Vieux Carré and Garden District. This baseline study investigates both vernacular and elite gardens of 159 drawings in the three oldest of the city Municipal Districts during the period 1810-1880, and identifies 19 garden templates. It sets the drawings in their social, political, and historical context to inform a critical understanding of the garden types. The inquiry examines 47 spatial and design variables, using the New Orleans Notarial Archive drawings, photographs, maps, and personal accounts as primary source materials. Quantitative data analysis methods, qualitative image analysis, site observation, and interviews with experts are used. Three products were derived from this study: Property Location Map, Property Variable Data Base, and Lexicon of the three Municipal District gardens. The study findings reveal that while individual properties sometimes vary within a particular garden template type variants are not geographically (and perhaps not culturally) dependant. The garden typology determinants are: space dependence, gardener program, environmental and cultural conditions, vegetation availability, resources, and consensus gardenways. All results are consistent with previous research conclusions. The 19 garden templates identified may be applied in period garden rehabilitation, restoration, and reconstruction

Social Exchange and the Maintenance of Order in Status-Stratified Systems

This paper examines the role of social exchange in the construction of microorder within status-differentiated relations. How order is constructed and maintained in the context of social inequality is a classic sociological problem. We use a serendipitous finding from a recent experiment as a stimulus for theorizing an important feature of this larger problem of order. The finding is that, in an experiment where African-American females negotiated with white males, the white males received much larger payoffs than the African-American females. Yet, despite substantial power and profit differentiation advantaging white males, both individuals reported positive feelings (pleasure/satisfaction and interest/excitement) to the same degree, which contradicts most research on emotional responses to power. We argue that these similar emotional responses, in the context of substantial payoff inequalities, are due to parallel, joint effects of (a) status processes that create and legitimate initial profit differences and (b) exchange processes that make salient a relationship between the actors during repeated exchange. This explanation integrates notions of status value, referential structure, and legitimacy from status theories with notions of relational cohesion and shared responsibility from exchange theories. Broadly, the paper proposes some ways to productively interweave ideas from status and exchange theories to explain the emergence or maintenance of enduring social inequalities

Trust as a mediator in the relationship between childhood sexual abuse and IL-6 level in adulthood

Childhood sexual abuse (CSA) has been shown to predict the coupling of depression and inflammation in adulthood. Trust within intimate relationships, a core element in marital relations, has been shown to predict positive physical and mental health outcomes, but the mediating role of trust in partners in the association between CSA and inflammation in adulthood requires further study. The present study aimed to examine the impact of CSA on inflammatory biomarkers (IL-6 and IL-1β) in adults with depression and the mediating role of trust. A cross-sectional survey data set of adults presenting with mood and sleep disturbance was used in the analysis. CSA demonstrated a significant negative correlation with IL-6 level (r = -0.28, p<0. 01) in adults with clinically significant depression, while trust showed a significant positive correlation with IL-6 level (r = 0.36, p < .01). Sobel test and bootstrapping revealed a significant mediating role for trust between CSA and IL-6 level. CSA and trust in partners were revealed to have significant associations with IL-6 level in adulthood. Counterintuitively, the directions of association were not those expected. Trust played a mediating role between CSA and adulthood levels of IL-6. Plausible explanations for these counterintuitive findings are discussed

Reduction in Chaetoceros populations by furanace

One of the most promising prophylactic agents being tested to control Penaeus monodon larval diseases is furanace (6-hydroxymethyl-2 2(5-nitro-2-furyl) vinyl pyridine). To evaluate further its suitability as a chemotherapeutic agent, its effects on the population growth of Chaetoceros calcitrans, the diatom used as feed for the zoeal stages, was examined. Chaetoceros populations of uniform density (initial density in all runs: 130-141x10 SUP-3 cells /ml) were placed in nine white, circular (382 sq cm), plastic basins. The physio-chemical characteristics of the culture water were as follows: salinity, 28 . 5-30 . 0 ppt; pH, 8 . 62-8 . 72; temperature, 23-25 . 5 degree C; dissolved oxygen, 7 . 1-9 . 3 ppm; nitrate, 0 . 03-0 . 07 ppm; and ammonia, 0 . 005-0 . 03 ppm. Preweighed furanace granules were dissolved in the culture water, with resulting concentrations of 1 and 2 mg/l (3 replicates each). A set of replicates without furanace served as the control. Population counts of the diatom were taken after 2, 4, 6, 8, and 10 hr exposures. After 4 hr, the population decreased in all three levels. The population in 2 mg/l furanace showed the lowest count and that in control the highest. The population means are not statistically different from one another. The results of the study show that the furanace causes reductions in Chaetoceros population at all durations of exposure

Collaboration and Gender Equity among Academic Scientists

Universities were established as hierarchical bureaucracies that reward individual attainment in evaluating success. Yet collaboration is crucial both to 21st century science and, we argue, to advancing equity for women academic scientists. We draw from research on gender equity and on collaboration in higher education, and report on data collected on one campus. Sixteen focus group meetings were held with 85 faculty members from STEM departments, separated by faculty rank and gender (i.e., assistant professor men, full professor women). Participants were asked structured questions about the role of collaboration in research, career development, and departmental decision-making. Inductive analyses of focus group data led to the development of a theoretical model in which resources, recognition, and relationships create conditions under which collaboration is likely to produce more gender equitable outcomes for STEM faculty. Ensuring women faculty have equal access to resources is central to safeguarding their success; relationships, including mutual mentoring, inclusion and collegiality, facilitate women’s careers in academia; and recognition of collaborative work bolsters women’s professional advancement. We further propose that gender equity will be stronger in STEM where resources, relationships, and recognition intersect—having multiplicative rather than additive effects

Gender in Engineering Departments: Are There Gender Differences in Interruptions of Academic Job Talks?

We use a case study of job talks in five engineering departments to analyze the under-studied area of gendered barriers to finalists for faculty positions. We focus on one segment of the interview day of short-listed candidates invited to campus: the “job talk”, when candidates present their original research to the academic department. We analyze video recordings of 119 job talks across five engineering departments at two Research 1 universities. Specifically, we analyze whether there are differences by gender or by years of post-Ph.D. experience in the number of interruptions, follow-up questions, and total questions that job candidates receive. We find that, compared to men, women receive more follow-up questions and more total questions. Moreover, a higher proportion of women’s talk time is taken up by the audience asking questions. Further, the number of questions is correlated with the job candidate’s statements and actions that reveal he or she is rushing to present their slides and complete the talk. We argue that women candidates face more interruptions and often have less time to bring their talk to a compelling conclusion, which is connected to the phenomenon of “stricter standards” of competence demanded by evaluators of short-listed women applying for a masculine-typed job. We conclude with policy recommendations

The Matter of Fit: The Law of Discrimination and the Science of Implicit Bias

This Article examines the fit between the law of discrimination and the science of implicit bias, including consideration of the legal standards that apply and a broad overview of the sociological and psychological literatures that are relevant to those standards. The Authors first set forth the legal framework within which the psychological and sociological research literatures must be considered. Although the legal standard is not entirely unambiguous, scientific research on implicit bias appears relevant to the basic empirical issues put in issue by the law. The Authors then review the general research literature on the phenomenon of implicit biases in order to determine whether it is sufficient to support expert opinion on this subject and, if so, in what ways. This review leads the Authors to conclude that the research available on implicit bias should be admitted in order to inform jurors generally about the existence of implicit bias, so that they might determine whether it was a motivating factor in the decision at issue in the case. The research literature, however, does not support allowing the expert witness to opine regarding whether the particular decision at issue was itself a result of implicit bias
