Biodiversity Knowledge Gaps on Wikipedia: A Cross-Lingual Analysis of Species Coverage and Contribution Patterns
Creators: name: Lubiana, Tiago
Publisher: name: Zenodo
Year: 2025

description: Grant proposal submitted to the Wikimedia Research Fund 2025  on 2025-04-16. Note: data and results are presented at a preliminary stage.Abstract: The Wikimedia projects function as a key infrastructure in the open knowledge ecosystem and a crucial role to play in tackling the current biodiversity crisis. To support this mission, this proposal aims to detect critical biodiversity knowledge gaps  analyzing the coverage and contribution patterns for species across multiple Wikipedia language editions. We will quantify which species are documented (and where), identify patterns of content contribution, and examine how different communities contribute to biodiversity topics. By illuminating underserved areas—such as local species missing from Portuguese Wikipedia or entire taxonomic groups overlooked globally— we will generate actionable strategies to improve and balance content. The project is led by a Brazilian  post-doctoral researcher and long-time Wikimedian, ensuring both academic rigor and deep community insight and will be advised by an experienced group of Wikimedians and biodiversity scholars at the Biodiversity Heritage Library - Wikimedia working group. By using methods from biodiversity informatics and leveraging Wikidata, the Global Biodiversity Information Facility and the Catalogue of Life, the project will generate generalizable insights on the patterns of Wikipedia contributions while supporting individual volunteers and Wikimedia community members. Identification of critical biodiversity knowledge gaps, thus, is a move towards Wikimedia’s 2030 strategic priority to include knowledge and communities that have been left out by structures of power and privilege. With a particular focus on English, Portuguese and Spanish Wikipedias and the  Latin American communities, the end goal is to provide the means scaling up the capacity for informed contributions on biodiversity, particularly for neglected species and underrepresented communities providing the basis for targeted actions for a more equitable “encyclopedia of life”, catering for the diversity of human and non-human life.

description: We study the interplay between two nontrivial boundary effects: (1) the two dimensional ($2d$) edge states of three dimensional ($3d$) strongly interacting bosonic symmetry protected topological states, and (2) the boundary fluctuations of $3d$ bulk disorder-to-order phase transitions. We then generalize our study to $2d$ gapless states localized at an interface embedded in a $3d$ bulk, when the bulk undergoes a quantum phase transition. Our study is based on generic long wavelength descriptions of these systems and controlled analytic calculations. Our results are summarized as follows: ($i.$) The edge state of a prototype bosonic symmetry protected states can be driven to a new fixed point by coupling to the boundary fluctuations of a bulk quantum phase transition; ($ii.$) the states localized at a $2d$ interface of a $3d$ SU(N) quantum antiferromagnet may be driven to a new fixed point by coupling to the bulk quantum critical modes. Properties of the new fixed points identified are also studied.

description: This paper analyzes the signaling effect of bidding in a two-round elimination contest. Before the final round, bids in the preliminary round are revealed and act as signals of the contestants’ private valuations. Depending on his valuation, a contestant may have an incentive to bluff or sandbag in the preliminary round in order to gain an advantage in the final round. I analyze this signaling effect and characterize the equilibrium in this game. Compared to the benchmark model, in which private valuations are revealed automatically before the final round and thus no signaling of bids takes place, I find that strong contestants bluff and weak contestants sandbag. In a separating equilibrium, bids in the preliminary round fully reveal the contestants’ private valuations. However, this signaling effect makes the equilibrium bidding strategy in the preliminary round steeper for high valuations and flatter for low valuations compared to the benchmark model.
A functional analysis of the olfactory thalamocortical system using an asymmetrical lesion paradigm
Creators: name: McBride, Sharon Anne
Publisher: name: American University
Year: 2023

description: The central segment of the mediodorsal nucleus of the thalamus (MD) in the rat receives an olfactory input from the olfactory cortex and, in turn, projects to the lateral orbital and agranular insular cortex. Prior studies found that bilateral lesions of MD produce deficits in olfactory reversal learning tasks, but not on simple odor detection or two-odor discrimination tasks (Slotnick and Kaneko, 1981; Slotnick and Risser, 1990). Because such lesions also destroy non-olfactory components of the thalamus and produce deficits in a variety of non-olfactory tasks, it is unclear whether olfactory deficits stem specifically from disruption of the olfactory component of MD. To investigate this, the olfactory thalamocortical system of the rat was disrupted bilaterally using asymmetrical lesions. Subjects were then tested for odor detection, discrimination and reversal learning. Specifically, experimental rats received one of the following lesion combinations: (1) bilateral lesions of MD (BiMD group); (2) a unilateral bulbectomy and contralateral lesion of MD (RLBulb group); (3) a unilateral bulbectomy and contralateral lesion of MD combined with transection of the anterior commissure (RLBulbAC group); or (4) a unilateral lesion of the cortical projection targets of MD and a contralateral lesion of MD (RLCort group). In general, rats in each group made few errors on the odor detection and discrimination tasks. However, rats in the RLBulbAC, RLCort and BiMD groups made 2 to 3 times more errors than controls on the odor reversal tasks. Rats with similar lesions that spared the olfactory components of the system performed at control levels. In this study the characteristic reversal deficit of rats with bilateral MD lesions was reproduced with asymmetrical lesions whose only commonality was disruption of the olfactory thalamocortical system. This outcome indicates that olfactory deficits obtained from bilateral damage to MD are due to disruption of the olfactory component of this nucleus. Finally, rats in the RLBulb group made more errors than controls on the reversal task, but did not perform as poorly as the RLBulbAC group. These data demonstrate that functional olfactory information can be transferred interhemispherically via the anterior commissure.

description: This dissertation explores the role of Salvadoran refugee popular religion in processes of sociopolitical change underway in El Salvador. Using the approach of culture history it examines the civil war against the material social process and political developments of Salvadoran society. It focuses on how the civil war produced refugees and catalyzed a new expression of Christianity which I term the religion of martyrology. The symbol system and discourse of the religion of martyrology as expressed in ritual events and refugee testimony are of special concern to this inquiry. The testimony of three men and three women form part of this study's ethnographic representation. Salvadoran refugee testimony draws together the themes of popular religion in the setting of the civil war to effectively give shape to an oppositional identity that functions as a basis to judge and criticize political domination and economic exploitation. Salvadoran refugee testimony is part of a discourse of power that uses culture and the symbol system of the religion of martyrology to activate alternative political values and behavior aimed at establishing democratic rule in El Salvador. Salvadorans exist in a state of liminality in the States given their "illegal" status. Salvadoran refugees as a liminal group demarginalize themselves by building a cross-cultural and multi-class solidarity movement and remaining connected to the democratizing imperative characteristic of El Salvador's confrontational culture. From liminal spaces such as mutual assistance organizations and small Christian communities, refugee contestational identity is shaped and amended. Popular religion constitutes refugee identity and culturally reconstructs the experience of powerlessness in U.S. society into a distinctive social force.
title: Identification of genes involved in Citif1 promoter activation and endoderm differentiation
Creators: name: Lania, Gabriella
Publisher: name: The Open University
Year: 2004

description: In tadpole larva of the ascidian Ciona intestinalis (one of the most basal chordate) the endoderm is a simple tissue comprising about 500 cells. The commitment of endoderm occurs very early; in a 64-cells stage embryo five blastomeres pairs are restricted to endodermal fate. Although three genes, that exhibit an endoderm specific expression, Ci-alkaline phosphates, Cs-lhx3 and Cititf1 have been cloned, it remains to be elucidated how the first step of endoderm specification take place. As first strategy, I cloned a Ciona SoxE gene; this was found not to be endodermally expressed. In a second strategy, I focused on Cititf-1, a gene homologous to mammalian Nkx2.1 and the earliest zygotic endoderm specific marker isolated from Ciona thus far. Although its temporal and spatial expression seems to be finely regulated, the factors involved in its activation and likely involved in endoderm specification are unknown. The minimal region responsible for endodermal expression of Cititf1, has previously been located to a genomic fragment of about 200 base pairs upstream to putative TATA box sequence (Fanelli A. et al., 2003 Developmental Biology. 263, 12-23). Here I describe two imperfect repeats of eleven nucleotides, named R1 and R2, within this region and investigate their involvement in the transcriptional activation of Cititf1 promoter. Biochemical analyses showed that both repeats bind factors from ascidian embryos in a sequence-specific manner. The R2, however, is more important for endoderm specific expression and is able to drive the endodermal expression of a reporter gene. The R1 repeat cooperates with R2 to enhance this expression. A yeast one-hybrid screening was performed, leading to identification of a putative DNA-binding factor that could be involved in the regulation of Cititf1 in endoderm.

Body-image dissatisfaction and eating attitudes in mothers and daughters
Creators: name: Goldberg, Elaine Sue
Publisher: name: American University
Year: 2023

description: The present study investigated body-image dissatisfaction, chronic dieting, and negative eating attitudes, three attributes often associated with the development of eating disorders, particularly in women. A population of mothers (N = 133) and their daughters from three age groups--child, preadolescent, and adolescent (N = 151)--recruited from a suburban pediatric practice was studied. Body-image dissatisfaction was measured using the silhouette technique developed by Williamson, Davis, Goreczny, and Blouin (1989), together with a newly devised set of silhouettes for use with girls called the Figure Assessment Technique (FAT). Mothers and daughters were asked to keep three-day diet records. Mothers and adolescents were administered the EDI, EAT, and the Restraint Scale. In addition, Body Mass Index was calculated for each participant. Findings by Williamson et al. (1989) and Fallon and Rozin (1988), that women desire a thinner ideal body shape than their current body shape, were replicated and extended to adolescents and preadolescents. In addition, the present study found significantly greater body image dissatisfaction among adolescents and preadolescents than younger latency-age girls. Body-image dissatisfaction for adolescents was comparable to that for adult women. A high Body Mass Index (BMI) was found to be highly predictive of body-image dissatisfaction in both mothers and adolescent daughters. Adolescent EDI and RS responses confirmed their preoccupation with dieting and the pursuit of thinness within this group. In addition, daughters restricted their caloric intake when mothers were chronic dieters, suggesting that daughters imitated their mother's dieting behavior.

description: The contribution to the nuclear transverse response function R_T arising from two particle-two hole (2p-2h) states excited through the action of electromagnetic meson exchange currents (MEC) is computed in a fully relativistic framework. The MEC considered are those carried by the pion and by Delta degrees of freedom, the latter being viewed as a virtual nucleonic resonance. The calculation is performed in the relativistic Fermi gas model in which Lorentz covariance can be maintained. All 2p-2h many-body diagrams containing two pionic lines that contribute to R_T are taken into account and the relative impact of the various components of the MEC on R_T is addressed. The non-relativistic limit of the MEC contributions is also discussed and compared with the relativistic results to explore the role played by relativity in obtaining the 2p-2h nuclear response.

description: Recent developments allow a nonparametric separation of the continuous sample path component and the jump component of realized volatility. The jump component has very dierent time series properties than the continuous component, and accounting for this allows improved forecasting of future realized volatility. We investigate the potential forecasting role of implied volatility backed out from option prices in the presence of these new separate realized volatility components. We show that implied volatility has incremental information relative to both the continuous and jump components of realized volatility when forecasting subsequently realized return volatility, and it appears to be an unbiased forecast. Furthermore, implied volatility has predictive power for future values of each component of realized volatility separately, showing in particular that even the jump component of realized volatility is, to some extent, predictable.

description: We propose an extension of the standard model with Majorana-type fermionic dark matters based on the flatland scenario where all scalar coupling constants, including scalar mass terms, vanish at the Planck scale, i.e. the scalar potential is flat above the Planck scale. This scenario could be compatible with the asymptotic safety paradigm for quantum gravity. We search the parameter space so that the model reproduces the observed values such as the Higgs mass, the electroweak vacuum and the relic abundance of dark matter. We also investigate the spin-independent elastic cross section for the Majorana fermions and a nucleon. It is shown that the Majorana fermions as dark matter candidates could be tested by dark matter direct detection experiments such as XENON, LUX and PandaX-II. We demonstrate that within the minimal setup compatible with the flatland scenario at the Planck scale or asymptotically safe quantum gravity, the extended model could have a strong predictability.

description: A simple model of a quantum clock is applied to the old and controversial problem of how long a particle takes to tunnel through a quantum barrier. The model I employ has the advantage of yielding sensible results for energy eigenstates, and does not require the use of time-dependant wave packets. Although the treatment does not forbid superluminal tunneling velocities, there is no implication of faster-than-light signaling because only the transit duration is measurable, not the absolute time of transit. A comparison is given with the weak-measurement post-selection calculations of Steinberg.

We find that implied volatility is an informationally efficient but biased forecast of future realized exchange rate volatility. Furthermore, we show that log-normality is an even better distributional approximation for implied volatility than for realized volatility in this market. Finally, we show that the jump component of future realized exchange rate volatility is to some extent predictable, and that option implied volatility is the dominant forecast of the future jump component.

description: We construct invariant differential operators acting on sections of vector bundles of densities over a smooth manifold without using a Riemannian metric. The spectral invariants of such operators are invariant under both the diffeomorphisms and the gauge transformations and can be used to induce a new theory of gravitation. It can be viewed as a matrix generalization of Einstein general relativity that reproduces the standard Einstein theory in the weak deformation limit. Relations with various mathematical constructions such as Finsler geometry and Hodge-de Rham theory are discussed.

description: U.S. consumer demand for organically produced goods has grown continuously since the USDA established national standards for organic production and processing in 2002 (www.USDA.gov). Organic food sales have increased from approximately $11 billion in 2004 to an estimated $35.9 billion in 2015. As previous literature suggests, a large portion of consumers view organics favorably, but very few routinely choose to buy organic food over conventional food. It is assumed that this is due to—among other things— socioeconomic disparities. The objective of this paper is to predict the characteristics of consumers who are willing to pay high premiums for organic produce in the mid-Atlantic United States. In the context of this paper, a high premium is defined as at least 16% more for organic fruits and vegetables compared to conventional produce. Data were collected from 1,100 consumers using a private online survey company. A logit model was developed to predict which consumers are more likely to pay a high premium for organic produce. Results indicate that the overall model is highly significant, with a correct prediction rate of 71%. Those who have a graduate degree and an annual income above $100,000 are more likely to pay high premiums. Moreover, those who use food advertisements, certified organic labels, and natural labels to purchase produce are more likely to pay high premiums. Caucasians are more likely to pay high premiums, as are those who frequently buy at farm direct markets. As expected, consumers who think that organic food tastes better than conventional food and those who switch supermarkets to buy organic produce are more likely to pay high premiums. Those who want to buy organic jam, jelly, marmalade, juices, sauces, and dried chips are more likely to pay a high premium for organic produce. Those who regularly shop at more than one food store are less likely to pay a high premium. The model indicates that those who are influenced by the naturally grown label and prefer conventionally grown but local produce are less likely to pay high premiums. Those who consider buying organic food to be a waste of money are less likely to pay a high premium for organic fresh fruits and vegetables. Producers of organic vegetables and fruits can target customers with these specific traits to enhance their profitability.

description: Foreign policy is the outcome of a complex interaction among situational variables at the global, regional, bilateral, and domestic levels, which are filtered through a country's unique perceptual prism. While recognizing the role of perceptual factors in Soviet foreign policy, this study stresses the importance of situational variables in foreign policy formulation. It is asserted that, like other countries in the international system, the Soviet Union responded to the demands of realpolitik, pursued its national interest, and tried to maximize its power. This study attempts to delineate the determinants of Soviet policy toward Pakistan and to draw some general conclusions about Soviet foreign policy behavior. The author challenges many dominant assumptions and explanations regarding Soviet policy toward Pakistan and provides alternative interpretations of particular policies and events. The relative impact of global, regional, and bilateral factors on Soviet policy toward Pakistan is analyzed for the period 1960-1971. Hypotheses at each level establish linkages between changes in Soviet relations with other countries and fluctuations in Soviet-Pakistan relations. At the global level, Soviet-Chinese relations were found to be most significant in the determination of Soviet policy toward Pakistan; at the regional level, Soviet-Indian relations were most significant; and at the bilateral level, Pakistan-China relations were most significant. In comparing variables from these three levels, inputs from the global level were found to have the maximum influence on the formulation of Soviet policy toward Pakistan. This dissertation is a contribution to the literature on foreign policy analysis and Soviet studies in several ways: a case study approach is successfully combined with a broader theoretical and conceptual framework; hypotheses regarding the influence of variables at different levels of analysis are empirically tested; and, unlike previous studies, the Soviet perspective of events is presented. Finally, the multi-level approach employed here provides a more comprehensive understanding of Soviet objectives toward Pakistan. The conceptual framework and hypotheses outlined in this dissertation can be used to study Soviet-Pakistan relations in other periods and also Soviet relations with other countries.
Biodiversity Knowledge Gaps on Wikipedia: A Cross-Lingual Analysis of Species Coverage and Contribution Patterns
Creators: name: Lubiana, Tiago
Publisher: name: Zenodo

description: The grant proposal was submitted to the Wikimedia Research Fund 2025  on 2025-04-16. Notes: 1. Data and results are presented at a preliminary stage.2. Version 1 ended up with some (frankly embarrassing) proofreading errors. I blame it on the ADHD and having the flu right on the final sprint. Abstract: The Wikimedia projects function as a key infrastructure in the open knowledge ecosystem and play a crucial role in tackling the current biodiversity crisis. To support this mission, this proposal aims to detect critical biodiversity knowledge gaps by analyzing the coverage and contribution patterns for species across multiple Wikipedia language editions. We will quantify which species are documented (and where), identify patterns of content contribution, and examine how different communities contribute to biodiversity topics. By illuminating underserved areas—such as local species missing from Portuguese Wikipedia or entire taxonomic groups overlooked globally— we will generate actionable strategies to improve and balance content. The project is led by a Brazilian post-doctoral researcher and long-time Wikimedian, ensuring both academic rigor and deep community insight, and will be advised by an experienced group of Wikimedians and biodiversity scholars at the Biodiversity Heritage Library - Wikimedia working group. By using methods from biodiversity informatics and leveraging Wikidata, the Global Biodiversity Information Facility, and the Catalogue of Life, the project will generate generalizable insights on the patterns of Wikipedia contributions while supporting individual volunteers and Wikimedia community members. Identification of critical biodiversity knowledge gaps, thus, is a move towards Wikimedia’s 2030 strategic priority to include knowledge and communities that have been left out by structures of power and privilege. With a particular focus on English, Portuguese and Spanish Wikipedias and the  Latin American communities, the end goal is to provide the means scaling up the capacity for informed contributions on biodiversity, particularly for neglected species and underrepresented communities providing the basis for targeted actions for a more equitable “encyclopedia of life”, catering for the diversity of human and non-human life.

description: We study the information content of nuclear masses from the perspective of global models of nuclear binding energies. To this end, we employ a number of statistical methods and diagnostic tools, including Bayesian calibration, Bayesian model averaging, chi-square correlation analysis, principal component analysis, and empirical coverage probability. Using a Bayesian framework, we investigate the structure of the 4-parameter Liquid Drop Model by considering discrepant mass domains for calibration. We then use the chi-square correlation framework to analyze the 14-parameter Skyrme energy density functional calibrated using homogeneous and heterogeneous datasets. We show that a quite dramatic parameter reduction can be achieved in both cases. The advantage of Bayesian model averaging for improving uncertainty quantification is demonstrated. The statistical approaches used are pedagogically described; in this context this work can serve as a guide for future applications.

AIDS, gender and behavior change: Women's responses to the pandemic in urban Senegal
Creators: name: Lewis, Michelle Eileen
Publisher: name: American University

description: The findings presented here are the result of an eight month study conducted in Kaolack, Senegal's third largest town. This study looks at women's responses to the threat of AIDS in a predominantly Muslim and polygamous West African society that legalized prostitution in 1969. Thus, it examines the influence of the cultural environment on Senegalese women's willingness and ability to negotiate safe sex in an arena in which they traditionally have had little power. To this end, I employed quantitative and qualitative research methods to assess the AIDS knowledge and behaviors of 68 prostitute and 32 non-prostitute women. As an evaluation of an AIDS campaign targeted at prostitutes in Kaolack, the study compares the responses of campaign participants to those of women who were not part of this or any other education campaign. Informal and formal interviews with both groups of women yielded information about the demographics of the study sample as well as their sexual activities and perception of HIV risk. These data, coupled with participant observation in various settings, shed light on the factors affecting women's willingness and ability to control sexual activities as wives, girlfriends and prostitutes. The main finding of the study is that prostitutes targeted by the AIDS education campaign almost always enforce clients' condom use. This and other evidence testifies to the two-year program's significant success at impeding HIV transmission between prostitutes and their clients. However, in their roles as girlfriends, prostitutes do not always require their partners to wear condoms. Similarly, non-prostitute women are reluctant to discuss condoms with their partners. Like the prostitutes, they do not want to risk losing their husbands by implying one of them might be HIV positive. This dilemma reflects the economic and social dependence of Senegalese women on men and the compromises they make to retain long-term relationships that provide them with economic and social security. It points to the need for a program targeted at men that integrates the effective and culturally appropriate characteristics of the Kaolack AIDS campaign.
