Cocaine-induced conditioned taste aversions: Investigations of neurochemical mediation
Creators: name: Serafine, Katherine M.
Publisher: name: American University
Year: 2023

description: Drugs of abuse have both rewarding and aversive effects, and it is the balance of these effects which impact abuse vulnerability. Although research has traditionally focused on the rewarding effects of drugs, their aversive effects have recently gained increasing attention. The present series of investigations sought to determine the neurochemical mediation underlying conditioned taste aversions (CTA) induced by cocaine. Given the role of dopamine (DA) in cocaine reward, this neurotransmitter system is of particular interest. The present experiments used direct pharmacological antagonism (with the DA antagonist haloperidol) as well as cross-drug preexposure (with DA transporter [DAT] inhibitor GBR 12909) to determine a role, if any, of DA in the induction of CTAs by cocaine. Following the determination of behaviorally active doses of haloperidol with no aversive effects on their own (Experiment 1), animals were given 1 mg/kg haloperidol prior to various doses of cocaine in a taste aversion procedure (Experiment 2). Under these conditions, haloperidol blocked cocaine-induced CTAs (at 18 and 32 mg/kg). In separate experiments, cocaine (18 mg/kg; Experiment 3) or GBR 12909 (32 mg/kg; Experiment 4 or 50 mg/kg; Experiment 5) was administered prior to aversion conditioning with cocaine (18 mg/kg) and GBR 12909 (32 mg/kg). Under these conditions, GBR 12909 (at 50 mg/kg only) blocked cocaine-induced CTAs but the reverse serial presentation did not result in significant cross-drug attenuation, indicating that the aversive properties of GBR 12909 and cocaine are similar, but not identical. Although these results indicate a role of DA in cocaine-induced CTAs, the extent to which each DA receptor subtype plays a role remains unknown. These results are discussed in the context of previous work demonstrating roles for both norepinephrine (NE) and possibly serotonin (5-HT) in cocaine-induced CTAs. The neurochemical mediation of cocaine's aversive effects was discussed in the context of the neurochemical mediation of cocaine reward and the implications for drug abuse.

description: Chloroplast RNA processing requires a large number of nuclear-encoded RNA binding proteins (RBPs) that are imported post-translationally into the organelle. Most of these RBPs are highly specific for one or few target RNAs. By contrast, members of the chloroplast ribonucleoprotein family (cpRNPs) have a wider RNA target range. We here present a quantitative analysis of RNA targets of the cpRNP CP31A using digestion-optimized RNA co-immunoprecipitation with deep sequencing (DO-RIP-seq). This identifies the mRNAs coding for subunits of the chloroplast NAD(P)H dehydrogenase (NDH) complex as main targets for CP31A. We demonstrate using whole-genome gene expression analysis and targeted RNA gel blot hybridization that the ndh mRNAs are all down-regulated in cp31a mutants. This diminishes the activity of the NDH complex. Our findings demonstrate how a chloroplast RNA binding protein can combine functionally related RNAs into one post-transcriptional operon.

description: We quantify and discuss the footprints of neutral hydrogen in the intergalactic medium (IGM) on the spectra of high-redshift (z ~ 6) sources, using mock spectra generated from hydrodynamical simulations of the IGM. We show that it should be possible to extract relevant parameters, including the mean neutral fraction in the IGM, and the radius of the local cosmological Stromgren region, from the flux distribution in the observed spectra of distant sources. We focus on quasars, but a similar analysis is applicable to galaxies and gamma ray burst (GRB) afterglows. We explicitly include uncertainties in the spectral shape of the assumed source template near the Lyman alpha line. Our results suggest that a mean neutral hydrogen fraction, x(HI) of unity can be statistically distinguished from x(HI)<0.01, by combining the spectra of tens of bright (M = -27) quasars. Alternatively, the same distinction can be achieved using the spectra of several hundred sources that are ~100 times fainter. Furthermore, if the radius of the Stromgren sphere can be independently constrained to within ~10 percent, this distinction can be achieved using a single source. The information derived from such spectra will help in settling the current debate as to what extent the universe was reionized at redshifts near z=6.

description: It was recently pointed out that the existence of dark energy imposes highly restrictive constraints on effective field theories that satisfy the Swampland conjectures. We provide a critical confrontation of these constraints with the cosmological framework emerging from the Salam-Sezgin model and its string realization by Cvetic, Gibbons, and Pope. We also discuss the implication of the constraints for string model building.

The banking functions of the Hungarian urban network in the early 20th century
Creators: name: Gál, Zoltán
Publisher: name: RKK, Pécs
Year: 2006

description: This paper examines the impact of the Hungarian banking system on regional and urban development in the early 20th century, when local banks were important territorial elements of the financial space developing close links to regional economic structures. The basic concept of the study is that there is closer connection not only between the banking sector and the economy as a whole, but between the banking sector and urban development as well. This is coincided with the argument of the American Historical Geographical school (Conzen, 1977) says that the features of the urban network are in strong correlation with the spatial structure of banking system and the diffusion of financial innovations. We considered the spatial breakdown of capital flows are one of the most important indicators of the regional and urban transformation (Gál, 2005). The Hungarian banking system looks back to a history of more than 160 years. Examining the impact of the banking system on regional and urban development is reasonable in the second half of the 19th century, since in Hungary developed an extensive financial system with a well researchable statistical database (Vargha, 1913). The Hungarian banking system was well developed in comparison to international standards by the first decade of the 20th century (Kövér, 1991; Tomka, 1996). Moreover, it became one of the most rapidly growing sectors of the domestic economy of that time ...

description: This paper examines marketing choices by southwestern cotton producers in 2010. Producer marketing behavior was modeled in a multinomial logit framework as a discrete choice among forward contracting with a merchant; postharvest cash contracting with a merchant; contracting with a merchant pool; or contracting with a cooperative pool. The most important determinants of cotton cash marketing choices were prior participation in cooperative pools, beliefs about the value of preharvest pricing, beliefs about the performance of merchant pools, willingness to accept lower prices to reduce risk, and several socio-economic variables.
Policing the New Downtown: The Costs of Community for Homeless Persons and Individuals with Mental Illness in Washington, D.C.

Year: 2023

description: This research project is an ethnographic account of the effects of neoliberal social, economic and urban development policies since the 1980s on the interactions between police officers and homeless persons and individuals with mental illness in Washington, D.C. These interactions are comprehended through the perspectives of police officers, homeless men and women with mental illness, their advocates, mental health and criminal justice professionals and public employees. Together, these perspectives shed light on the intersections of criminal justice, mental health and urban development policies with poverty, economic inequality and the rhetorical and practical workings of community.Since the early 1980s, neoliberal social and economic policies that promote privatization, deregulation and punitive crime control have dramatically impacted the mental health and criminal justice systems, often in consequence of one another. As mental health care has been privatized and marketized, the social safety net available in the public sector has been dramatically reduced. Combined with the loss of affordable housing in cities, the number of homeless individuals with mental illness has grown. Consequently, contact between law enforcement and homeless individuals with mental illness has increased, often at the prompting of vocal community opposition to the presence of the homeless. Neoliberal economic policies have also reshaped the landscape of cities as local governments have become reliant on large-scale downtown urban development projects to draw in capital, while at the same time carving cities into exclusive enclaves of privilege. Business and community opposition to the use of public space by homeless individuals in downtown cores has increasingly become the catalyst for interactions between police officers and homeless individuals, many with mental illness. Homeless outreach workers employed by business improvement districts in Washington, D.C. have created informal partnerships with police officers to mediate these interactions, creating a model of best practice for jail diversion. However, these informal public-private partnerships ultimately promote the removal of homeless individuals from public space and privilege the workings of community on behalf of businesses and city elite.This paper concludes that to build a truly living city, we must tackle the foundational issues of poverty and economic inequality that create homelessness and at the same time, hold civic leaders, business elite and public agencies accountable for their role in the promotion of exclusionary practices in the name of community.

description: Morphological integration is defined as covariation of multiple parts of the morphological traits. Modularity is characterized by the presence of subunites (modules), which have high level of integration within themselves, but weak between themselves. In this respect, differences in function, anatomical structure and embrionical origin of modules can influence development and function of organism. The aim of our study was to test the hypothesis that the distal region of the head capsule is a modul in Megaphyllum unilineatum using geometric morphometrics. Millipedes belonging to postembryonic stadia VI to XI were collected from Krnjača, Belgrade. The ontogenetic stadia were determined by counting the number of rows of ocelli, the total number of ocelli and rings, and the number of rings with and without walking legs. In data processing, the following statistical programs were used: MakeFan, TpsDig, CoordGen, MorphoJ, and R program. Procrustes ANOVA showed that individual × side interaction was significant. Allometry was significant for the symmetric component (SC), but not for the asymmetric component (FA). Since covariance coefficients (RV) for SC and FA had lower values than 10.4% and 13.8% (respectively) of other RV coefficients obtained by a random contiguous partition of dorsal part of the head capsule, modularity hypothesis is rejected. Further, the scaled variance of the eigenvalues of the SC (EV) was significantly lower before than after allometry removal. These results indicate that distal and proximal regions of the head capsule, due to their strongly morphological integration, develop and function as a module during ontogeny in this species.
title: Vagueness in mathematics talk
Creators: name: Rowland, Timothy
Publisher: name: The Open University
Year: 1996

description: The Cockcroft Report claimed that "mathematics provides a means of communication which is powerful, concise and unambiguous". Such precision in language may be a conventional aim of mathematics, particularly when communicated in writing. Nonetheless, as this thesis demonstrates, vagueness is commonplace when people talk about mathematics. In this thesis, I examine the circumstances in which vagueness arises in mathematics talk, and consider the practical purposes which speakers achieve by means of vague utterances in this context. The empirical database, which is considered in Chapters 4 to 7, consists almost entirely of transcripts of mathematical conversations between adult interviewers (including myself) and one or two children. The data were collected from clinical interviews focused on a small number of tasks, and from fragments of teaching. For the most part, the pupils involved in the study were aged between 9 and 12, although the age-range in Chapter 7 extends from 4 to 25. I draw on a number of approaches to discourse associated with 'pragmatics' -a field of linguistics - to analyse the motives and communicative effectiveness of speakers who deploy vagueness in mathematics talk. I claim that, for these speakers, vagueness fulfills a number of purposes, especially 'shielding', i. e. self-protection against accusation of being wrong. Another purpose is to give approximate information; sometimes to achieve shielding, but also to provide the level of detail that is deemed to be appropriate in a given situation. A different purpose, associated with a particular form of vagueness (of reference), is to compensate for lexical gaps in pursuit of effective communication of concepts and ideas. I show, in particular, how speakers use the pronouns 'it' and 'you' in mathematics talk to communicate concepts and generalisations. Some consideration is given to the intentions of 'expert speakers of mathematics when they deploy vague language. Their purposes include some of those identified for novices. Teachers also use vagueness as a means of indirectness in addressing pupils; this strategy is associated with the redress of 'face threatening acts'. My thesis is that vagueness can be viewed and presented, not as a disabling feature of language, but as a subtle and versatile device which speakers can and do deploy to make mathematical assertions with as much precision, accuracy or as much confidence as they judge is warranted by both the content and the circumstances of their utterances. I report on the validation and generalisation of my findings by an Informal Research Group of school teachers, who transcribed and analysed their own classroom interactions using the methods I had developed.

description: Black girls' participation in the college-bound process is associated with their self-perception and expectations of themselves. Students who expect to achieve their educational goals and possess a positive self-perception engage in activities that can fulfill college aspirations. The role of education in acquiring social and economic capital is complex, but higher education is associated with access to high-quality jobs and greater incomes. Black girls who are confident about their worth and their potential are more likely to enhance their academic potential by engaging in activities that further their post-secondary opportunities.These activities can range from determining the educational requirements for their occupational goals to taking courses of study that are academically appropriate for college readiness. Using the National Educational Longitudinal Study of 1988(NELS:88) which contains a nationally representative sample of school-aged Black, non-Hispanic girls to analyze a variety of measures indicating participation in the college preparation process, this study seeks to explore: the impact of self-perception and educational expectation on Black girls' participation in academic activities that prepare them for going to college. This research will add to the understanding of Black girls' agency in the process of educational attainment.

description: When the sweet potato is planted from vine cuttings it passes through a difficult period of healing the wound and initiating roots. The initial treatment of the cutting is therefore, very important. The effects of four simple practices such as removal of leaves of cuttings versus non-removal, holding the cutting for two days and stimulating roots versus immediate planting, delayed versus immediate irrigation, and planting in the morning versus planting in the afternoon, were tested in small, replicated trials with four clones of sweet potato. Removal of leaves reduced respiration and water loss but delayed establishment and reduced yields. Holding cuttings two days and stimulating rooting increased the number of storage roots and thus yield. Delayed irrigation tended to reduce root size. Planting in the morning versus the afternoon did not significantly affect any yield components. Thus, leaves should be left on the cuttings, cuttings should be prerooted before planting, and immediate irrigation appears beneficial.

description: The 2D ferromagnets, such as CrX3 (X=Cl, Br and I), have been attracting extensive attentions since they provide novel platforms to fundamental physics and device applications. Integrating CrX3 with other electrodes and substrates is an essential step to their device realization. Therefore, it is important to understand the interfacial properties between CrX3 and other 2D materials. As an illustrative example, we have investigated the heterostructures between CrX3 and graphene (CrX3/Gr) from firstprinciples. We find unique Schottky contacts type with strongly spin-dependent barriers in CrX3/Gr. This can be understood by synergistic effects between the exchange splitting of semiconductor band of CrX3 and interlayer charge transfer. The spinasymmetry of Schottky barriers may result in different tunneling rates of spin-up and down electrons, and then lead to spin-polarized current, namely spin-filter (SF) effect. Moreover, by introducing X vacancy into CrX3/Gr, an Ohmic contact forms in spin-up direction. It may enhance the transport of spin-up electrons, and improve SF effect. Our systematic study reveals the unique interfacial properties of CrX3/Gr, and provides a theoretical view to the understanding and designing of spintronics device based on magnetic vdW heterostructures.
The environmental weed risk of revegetation and forestry plants

description: Concerns have been raised about the environmental weed risk of non-indigenous plants promoted for broad scale revegetation and farm forestry purposes in South Australia (SA). Environmental weeds are plant species that invade and dominate natural habitats beyond the species' native range. The wide scale planting of species for revegetation, forestry, agriculture and horticulture increases the likelihood that some species will naturalise (i.e., form a self-sustaining population) and invade native vegetation or other landuse systems. However, analyses of past invasions have shown that the majority of plant species introductions will be of negligible weed risk. In 2001 the PIRSA Revegetation Program and the State Revegetation Committee of South Australia commissioned the Animal and Plant Control Commission (APCC) to undertake a weed risk assessment of 20 plant species. Weed risk assessment is the use of standard, technical criteria to determine the relative weed threats posed by plant species ...

Investigating fragmentation conditions in self-gravitating accretion discs

description: The issue of fragmentation in self-gravitating gaseous accretion discs has implications both for the formation of stars in discs in the nuclei of active galaxies, and for the formation of gaseous planets or brown dwarfs in circumstellar discs. It is now well established that fragmentation occurs if the disc is cooled on a timescale smaller than the local dynamical timescale, while for longer cooling times the disc reaches a quasi-steady state in thermal equilibrium, with the cooling rate balanced by the heating due to gravitational stresses. We investigate here how the fragmentation boundary depends on the assumed equation of state. We find that the cooling time required for fragmentation increases as the specific heat ratio, gamma, decreases, exceeding the local dynamical timescale for gamma = 7/5. This result can be easily interpreted as a consequence of there being a maximum stress (in units of the local disc pressure) that can be sustained by a self-gravitating disc in quasi-equilibrium. Fragmentation occurs if the cooling time is such that the stress required to reach thermal equilibrium exceeds this value, independent of gamma. This result suggest that a quasi-steady, self-gravitating disc can never produce a stress that results in the viscous alpha parameter exceeding ~ 0.06.

By placing the Festival in the context of emergent discourses in the fields of museum studies, arts management, folklore, and anthropology, the study aims to analyze the complex influences involved in the programming of the Festival's featured country program. Through literary analysis, interviews with Festival curators, and case studies of past Festivals, the work acknowledges the presence and influence of cultural, political, economic, and social domains in the programming process. Additionally, by looking at three major influences on foreign programming choices - timing/availability, national interests, and funding - the study provides an example of the ways in which public cultural events can serve as sites for the living, changing enactment of national cultural policies.

description: Three field experiments, two at Field Stations and one on farmers' holdings, were conducted on yam and yam-based cropping systems in St. Lucia during 1985-86. A comparison of five cultivars of white yam (Yam Langie, Local White, Oriental Yam, Belep and Knnabayo) at the La Ressource Field Station, showed that Oriental Yam yielded significantly higher than the other cultivars both on a cycle-basis (39.8 t/ha) and on a day-basis (208 kg ha-1day-l), and also showed a high degree of tolerance to anthracnose. Intercropping of yam with cowpeas, snapbeans and dasheen at the Union Agricultural Station, or relay intercropping of yam with cowpeas and snapbeans on farmers' holdings in the southwest did not significantly lower the yields, or affect yield attributes of yam as compared to the sole crop. At Union, the different cropping systems did not delay the incidence nor reduce the severity of anthracnose on yam.

description: We introduce a very early universe model based on the thermodynamics of a gas of closed strings in a background which is non-perturbative in $α'$. Upon considering the fully $α'$-corrected equations extended to include certain anisotropic cosmological backgrounds, we describe the evolution of the system in three different stages parametrized by the gas' equation of state. Using standard string thermodynamical arguments, we start with an isotropic 10-dimensional universe inside the string scale and evolve it towards a universe with four large spacetime dimensions and six stabilized internal dimensions in the Einstein frame.

Programming the Smithsonian Folklife Festival: National Cultural Policies on the National Mall
Creators: name: Smith, Laura E.
Publisher: name: American University
Year: 2023

description: This work examines the Smithsonian Folklife Festival as a text for the enactment of national cultural policies and interests on an international stage. By placing the Festival in the context of emergent discourses in the fields of museum studies, arts management, folklore, and anthropology, the study aims to analyze the complex influences involved in the programming of the Festival's featured country program. Through literary analysis, interviews with Festival curators, and case studies of past Festivals, the work acknowledges the presence and influence of cultural, political, economic, and social domains in the programming process. Additionally, by looking at three major influences on foreign programming choices - timing/availability, national interests, and funding - the study provides an example of the ways in which public cultural events can serve as sites for the living, changing enactment of national cultural policies.
DO CASH TRANSFERS ALTER HOUSEHOLD COMPOSITION? EVIDENCE FROM SUB-SAHARAN AFRICA
Creators: name: Soares, Fernanda Assuncao
Publisher: name: American University
Year: 2023

description: Cash transfer programs have emerged as a core poverty reduction strategy and have been recently adopted by a few Sub-Saharan Africa countries, but there is a possibility that these programs have perverse effects on household behavior. This research uses experimental data from two cash transfer programs in Malawi and Kenya to evaluate the effects of cash transfer on household composition by focusing on the behavior of household members with respect to inwards and outwards migration. Analysis based on the data collected before and after the programs' implementation provide overall supportive evidence that cash transfers do alter household structure by affecting migration flows. The results show that in Kenya households that received transfers were more likely to send off young adult members, suggesting that the program provided resources to overcome short-term economic constrains. In contrast, in Malawi the provision of cash transfers increased the number of young adults in treatment households, although it is not clear if this is driven by new members joining the household or because members are less likely to leave. The discrepancy of findings between Malawi and Kenya suggests that programs with similar designs can have opposite effect when implemented in different context.

description: During the cropping seasons of 1984 and 1985, experimental trials were conducted on farmers' holdings in St. Vincent where tannia and/or dasheen were intercropped with lima beans. Economic analyses of the different intercropping systems indicated that farm incomes were increased from intercropping. Incomes from tannia and dasheen were higher due to the presence of bean intercrops in the system. Returns from beans in the intercrop systems were significantly greater than the additional cost of growing the bean in the systems.

description: A study was conducted, on five farms under carrots for the past five years, to test the effect of two selected intercropping systems on carrot yield. Root-knot nematode (Meloidogyne incognita) damage on carrots was compared with that on carrots grown in monoculture. Damage was estimated on a root gall index based on the number of galls and malformation of carrot roots which account for unmarketable yield. The chives-carrots and cabbage-carrots systems gave significantly lower unmarketable yield of carrot. The carrot monoculture gave the highest unmarketable yield. Total and marketable yields were not significant in the two intercropping systems as compared to carrot monoculture. When yields of carrot were adjusted for root gall index using covariance analysis it was found that the carrot monoculture had the highest unmarketable yield and root gall index (2.8).
