description: We present a chemical analysis of selected HII regions from the PHANGS-MUSE nebular catalogue. Our intent is to empirically re-calibrate strong-line diagnostics of gas-phase metallicity, applicable across a wide range of metallicities within nearby star-forming galaxies. To ensure reliable measurements of auroral line fluxes, we carried out a new spectral fitting procedure whereby only restricted wavelength regions around the emission lines of interest are taken into account: this assures a better fit for the stellar continuum. No prior cuts to nebulae luminosity were applied to limit biases in auroral line detections. Ionic abundances of O+, O++, N+, S+, and S++ were estimated by applying the direct method. We integrated the selected PHANGS-MUSE sample with other existing auroral line catalogues, appropriately re-analysed to obtain a homogeneous dataset. This was used to derive strong-line diagnostic calibrations that span from 12+log(O/H) = 7.5 to 8.8. We investigate their dependence on the ionisation parameter and conclude that it is likely the primary cause of the significant scatter observed in these diagnostics. We apply our newly calibrated strong-line diagnostics to the total sample of HII regions from the PHANGS-MUSE nebular catalogue, and we exploit these indirect metallicity estimates to study the radial metallicity gradient within each of the 19 galaxies of the sample. We compare our results with the literature and find good agreement, validating our procedure and findings. With this paper, we release the full catalogue of auroral and nebular line fluxes for the selected HII regions from the PHANGS-MUSE nebular catalogue. This is the first catalogue of direct chemical abundance measurements carried out with PHANGS-MUSE data.

description: Background In the Canadian Alliance for Healthy Hearts and Minds (CAHHM) cohort, participants underwent magnetic resonance imaging (MRI) of the brain, heart, and abdomen, that generated incidental findings (IFs). The approach to managing these unexpected results remain a complex issue. Our objectives were to describe the CAHHM policy for the management of IFs, to understand the impact of disclosing IFs to healthy research participants, and to reflect on the ethical obligations of researchers in future MRI studies. Methods Between 2013 and 2019, 8252 participants (mean age 58 ± 9 years, 54% women) were recruited with a follow-up questionnaire administered to 909 participants (40% response rate) at 1-year. The CAHHM policy followed a restricted approach, whereby routine feedback on IFs was not provided. Only IFs of severe structural abnormalities were reported. Results Severe structural abnormalities occurred in 8.3% (95% confidence interval 7.7–8.9%) of participants, with the highest proportions found in the brain (4.2%) and abdomen (3.1%). The majority of participants (97%) informed of an IF reported no change in quality of life, with 3% of participants reporting that the knowledge of an IF negatively impacted their quality of life. Furthermore, 50% reported increased stress in learning about an IF, and in 95%, the discovery of an IF did not adversely impact his/her life insurance policy. Most participants (90%) would enrol in the study again and perceived the MRI scan to be beneficial, regardless of whether they were informed of IFs. While the implications of a restricted approach to IF management was perceived to be mostly positive, a degree of diagnostic misconception was present amongst participants, indicating the importance of a more thorough consent process to support participant autonomy. Conclusion The management of IFs from research MRI scans remain a challenging issue, as participants may experience stress and a reduced quality of life when IFs are disclosed. The restricted approach to IF management in CAHHM demonstrated a fair fulfillment of the overarching ethical principles of respect for autonomy, concern for wellbeing, and justice. The approach outlined in the CAHHM policy may serve as a framework for future research studies. Clinical trial registration https://clinicaltrials.gov/ct2/show/NCT02220582 .

description: This thesis investigates sphingolipid metabolism in Parkinson’s Disease (PD) patients and individuals at high risk of PD, rapid eye movement sleep behavior disorder (RBD) patients. Serum analysis of idiopathic PD patients revealed reduced sphingolipids linked to glucocerebrosidase (GCase) dysfunction. Sebum studies in RBD patients identified early sphingolipid alterations, including shifts in ceramides. Mouse models with GCase deficiency demonstrated region-specific disruptions in sphingolipid pathway flux. These findings underscore sphingolipid pathway alterations as promising diagnostic and therapeutic targets. Preliminary development of an in situ GCase assay lays the groundwork for future clinical applications to improve understanding and treatment of PD and RBD.

description: In the realm of medical image analysis, self-supervised learning (SSL) techniques have emerged to alleviate labeling demands, while still facing the challenge of training data scarcity owing to escalating resource requirements and privacy constraints. Numerous efforts employ generative models to generate high-fidelity, unlabeled 3D volumes across diverse modalities and anatomical regions. However, the intricate and indistinguishable anatomical structures within the abdomen pose a unique challenge to abdominal CT volume generation compared to other anatomical regions. To address the overlooked challenge, we introduce the Locality-Aware Diffusion (Lad), a novel method tailored for exquisite 3D abdominal CT volume generation. We design a locality loss to refine crucial anatomical regions and devise a condition extractor to integrate abdominal priori into generation, thereby enabling the generation of large quantities of high-quality abdominal CT volumes essential for SSL tasks without the need for additional data such as labels or radiology reports. Volumes generated through our method demonstrate remarkable fidelity in reproducing abdominal structures, achieving a decrease in FID score from 0.0034 to 0.0002 on AbdomenCT-1K dataset, closely mirroring authentic data and surpassing current methods. Extensive experiments demonstrate the effectiveness of our method in self-supervised organ segmentation tasks, resulting in an improvement in mean Dice scores on two abdominal datasets effectively. These results underscore the potential of synthetic data to advance self-supervised learning in medical image analysis.

description: Periorbital segmentation and distance prediction using deep learning allows for the objective quantification of disease state, treatment monitoring, and remote medicine. However, there are currently no reports of segmentation datasets for the purposes of training deep learning models with sub mm accuracy on the regions around the eyes. All images (n=2842) had the iris, sclera, lid, caruncle, and brow segmented by five trained annotators. Here, we validate this dataset through intra and intergrader reliability tests and show the utility of the data in training periorbital segmentation networks. All the annotations are publicly available for free download. Having access to segmentation datasets designed specifically for oculoplastic surgery will permit more rapid development of clinically useful segmentation networks which can be leveraged for periorbital distance prediction and disease classification. In addition to the annotations, we also provide an open-source toolkit for periorbital distance prediction from segmentation masks. The weights of all models have also been open-sourced and are publicly available for use by the community.

description: Globimetula braunii is a hemi-parasitic plant used in African ethnomedicine for the management of microbial infections, rheumatic pain and tumors amongst others. We report the isolation and characterization of eight compounds with their antioxidant and antimicrobial activities. The air-dried powdered leaf was macerated in EtOH/H20 (4:1). The extract was solvent-partitioned into n-hexane, EtOAc, n-BuOH and aqueous fractions. The fractions were screened for their antioxidant properties, using DPPH, FRAP, TAC and FIC assays. Antimicrobial analysis was performed using the micro-broth dilution method. The active EtOAc fraction was purified for its putative compounds on a repeated silica gel column chromatography monitored with TLC-bioautography. The isolated compounds were characterized using spectroscopic methods of UV, FT-IR, NMR and MS. Eight compounds (1–8) were isolated and characterized as 13,27-cycloursane (1), phyllanthone (2), globraunone (3), three phenolics: methyl 3,5-dihydroxy-4-methoxybenzoate (4), methyl 3-methyl-4-hydroxybenzoate (5) and guaiacol (6), as well as two phenol derivatives: 4-formaldehyde phenone (7) and 6-methoxy-2H-inden-5-ol (8). The study identified 4 and 6 as natural antioxidant compounds with potential as antimicrobial agents.

description: We show how to use diagrammatic techniques to compute the weak-coupling perturbation series of the self-consistent solution to a Dynamical Mean Field Theory (DMFT) problem. This approach constitutes an alternative to using diagrammatic techniques directly as an impurity solver. It allows one to bypass the need of multiple perturbative series resummations within the DMFT self-consistency loop. It can be applied at or out of equilibrium, with any diagrammatic formalism, such as real times, imaginary times, or Matsubara frequencies formalisms. As a proof of principle, we illustrate our method with the half-filled Hubbard model on the Bethe lattice in the DMFT approximation, using Quantum Quasi-Monte Carlo (QQMC) to obtain the impurity perturbation series on the real time axis.

description: We evaluated families’ perspectives on the usability of virtual visits for routine gender care for trans youth during the COVID-19 pandemic. An online survey, which included a validated telehealth usability questionnaire, was sent to families who had a virtual Gender Clinic visit between March and August 2020. A total of 87 participants completed the survey (28 trans youth, 59 caregivers). Overall, usability was rated highly, with mean scores between “quite a bit” and “completely” in all categories (usefulness, ease of use, interface and interaction quality, reliability, and satisfaction). Caregivers reported higher usability scores compared to trans youth [mean (SD) 3.43 (0.80) vs. 3.12 (0.93), p = 0.01]. All families felt that virtual visits provided for their healthcare needs. A total of 100% of youth and caregivers described virtual appointments as safer or as safe as in-person visits. A total of 94% of participants would like virtual visits after the pandemic; families would choose a mean of two virtual and one yearly in-person visit with a multidisciplinary team. Overall, virtual gender visits for trans youth had impressive usability. Participants perceived virtual visits to be safe. For the future, a combination of virtual and in-person multidisciplinary visits is the most desired model.

description: In Flutter gibt es diverse Ansätze und Lösungsmöglichkeiten, den Zustand einer mobilen Anwendung zu verwalten. Flutter ist ein beliebtes Cross-Plattform-Framework, mit dem sich Anwendungen für iOS, Android, Web, Windows, Linux und macOS erstellen lassen, die den gleichen Quelltext verwenden. Damit sollen in der Entwicklung Aufwände gespart werden können und die Komplexität reduziert werden. Flutter baut auf eine deklarative Benutzeroberfläche, welche anhand eines Zustands erstellt wird. Die Verwaltung dieses Zustands ist entscheidend für die Architektur und die Funktion einer Anwendung. In dieser Ausarbeitung werden verschieden bereits etablierte Ansätze zur Verwaltung des Zustands einer Flutter-Anwendung dargestellt und untersucht. Dabei ist das Ziel, herauszufinden, welcher Ansatz am besten zum Verwalten des Zustands einer Flutter-Anwendung geeignet ist. Dafür wird eine Evaluation für die Zustandsverwaltungssysteme setState, InheritedWidget, BLoC, Provider, Riverpod, Redux und MobX durchgeführt. Grundlage dieser Evaluation ist die Entwicklung einer Beispielanwendung für jedes Zustandsverwaltungssystem und die Bewertung dieser anhand von qualitative und quantitativen Bewertungskriterien, die anhand der Anforderungen an Zustandsverwaltungssysteme definiert werden. Das Ergebnis der Arbeit stellt neben den Resultaten der Evaluation auch eine Empfehlung dar, welches Zustandsverwaltungssystem für welchen Anwendungsfall am besten genutzt werden sollte.
description: Flutter has multiple approaches in managing the state of an application. Flutter is a popular cross-platform framework for the development of applications for iOS, Android, Web, Windows, Linux and macOS. It offers the advantage to develop one codebase for multiple platforms at once resulting in reduced costs and complexity. Flutter uses a declarative UI that renders widgets based on a given state. The state management of a Flutter application is one of the most important parts of an application influencing the architecture and structure of an application. This thesis describes multiple already existing approaches for state management in Flutter. The objective is to determine which approach is the most suitable approach for managing state in Flutter. In order to meet this objective, an evaluation will be carried out by evaluating the state management approaches setState, InheritedWidget, BLoC, Provider, Riverpod, Redux and MobX. An example application will be implemented for every approach. Those applications will be assessed by qualitative and quantitative criteria based on the requirements of state management systems for Flutter. The result, in addition of the evaluation assessments, is also a recommendation which approach to use for a specific use case.

description: Background: Cognitive impairment is a prevalent and impactful non-motor symptom of
Parkinson's disease (PD), affecting 20-50% of newly diagnosed patients. Early detection of
cognitive decline is important for timely intervention, but current prediction models lack
generalizability across diverse PD populations.
Aim: To develop and validate machine learning models using multi-cohort data to predict both
mild cognitive impairment (MCI) and patient-reported cognitive impairment (PRCI) in PD
patients.
Methods: We applied a multi-cohort machine learning approach using data from three
independent PD cohorts (LuxPARK, PPMI and ICEBERG). Different algorithms were used
for classification and time-to-event analysis. Cross-study normalization and leave-one-cohort-
out validation were applied to improve and assess model generalizability.
Results: Multi-cohort models showed improved stability of performance measures compared
with single-cohort models. Age at PD onset and visuospatial ability (measured by the Benton
Judgment of Line Orientation) emerged as key predictors for both MCI and PRCI. Sex
differences were observed for PRCI, with men more likely to report cognitive impairment.
Non-motor symptoms, particularly autonomic dysfunction, were associated with an increased
risk of cognitive decline.
Conclusions: Our multi-cohort machine learning approach identified robust predictors of
cognitive impairment in PD, providing improved generalizability over single-cohort studies.
These findings offer practical insights for early detection and personalized management of
cognitive decline in PD patients.

title: Discursive AI infrastructures : envisioned and overlooked museum futures
Creators: name: Kist, Cassandra

description: Prompted by recent innovations, artificial intelligence (AI) is increasingly being discussed across the museum sector regarding its implications for institutional roles and practices. However, AI in particular, is an ambiguous term, a ‘black box’ which is capable of containing and reflecting numerous values and ideals (Crawford, 2021). This paper positions discourse around AI as a ‘discursive’ infrastructure, capable of not only embodying ideals but also shaping and justifying certain institutional practices and roles. This paper thematically analyses 115 pieces of grey literature produced and shared by professional governance bodies in the museum sector from 1995–2023, mainly across Canada, the United Kingdom, and the United States. In doing so, it identifies four preliminary themes encompassing shifts in discourse over time which give shape to a contemporary discursive infrastructure. This prompts timely critical reflections of museum professionals and stakeholders on both imagined and overlooked public roles, responsibilities, and practices of the museum in relation to AI.

Η  ανάπτυξη  του  UAV  στοχεύει  στη  δημιουργία  ενός  ευέλικτου  και  ενεργειακά  αυτόνομου  συστήματος  που  θα  μπορεί  να  αξιοποιηθεί  για
περιβαλλοντική  παρακολούθηση  σε  απομακρυσμένες  και  δυσπρόσιτες  περιοχές,  όπου  η πρόσβαση  είναι  δύσκολη  μέσω  παραδοσιακών  μεθόδων.  Σημαντική  καινοτομία  της  εργασίας αποτελεί  η  ενσωμάτωση  φωτοβολταϊκών  κυψελών  C60  στις  πτέρυγες  του  UAV,  με  σκοπό  την επέκταση  της  διάρκειας  πτήσης  μέσω  της  παραγωγής  ενέργειας  κατά  τη  διάρκεια  της αποστολής.  Οι  κυψέλες  αυτές  επιτρέπουν  την  αύξηση  της  ενεργειακής  αυτονομίας,
διευρύνοντας  τις  δυνατότητες  χρήσης  του  UAV  για  παρατεταμένες αποστολές.  Η  εργασία περιλαμβάνει  ανασκόπηση  της  τεχνολογίας  UAV  και  VTOL  συστημάτων,  με  έμφαση  στην ηλιακή  ενέργεια  και  τις  δυνατότητες  που  προσφέρει  για  τη  βελτίωση  της  αυτονομίας  των πτήσεων. Παρουσιάζεται  η  διαδικασία  σχεδιασμού  και  τροποποίησης  του  εμπορικού  μοντέλου Skyhunter  για  να  υλοποιηθεί  η  διάταξη  VTOL,  ενώ  αναλύονται  οι  τεχνικές  προκλήσεις  και  η επιλογή  υλικών  και  εξαρτημάτων.  Αν  και  δεν  έχουν  πραγματοποιηθεί  ακόμα  δοκιμαστικές πτήσεις,  η  κατασκευή  του  UAV  έχει  ολοκληρωθεί  και  προσφέρει  δυνατότητα  μελλοντικής προσαρμογής αισθητήρων  για  περιβαλλοντική  παρακολούθηση.  Τα  ευρήματα  δείχνουν  ότι,  η ενσωμάτωση  ηλιακής  ενέργειας  είναι  πολλά  υποσχόμενη  για  την  επίτευξη  αυξημένης ενεργειακής  αυτονομίας,  και  η  σχεδιαστική  ευελιξία  του  UAV  επιτρέπει  την  ενσωμάτωση αισθητήρων για αποστολές περιβαλλοντικής παρακολούθησης στο μέλλον.
description: The elaboration of this dissertation aims at the construction of an Unmanned VTOL(Vertical Take-off and Landing) Aerial Vehicle by using batteries and solar cells. The use of solar cells aims to increase flight time and also its autonomy in relation to flight time using only batteries. At the same time there will be the possibility of payload with the aim of attaching various sensors for specific purposes such us the measurement of pollutants in the atmosphere, as well as the possibility of automatic flight using GPS. For this purpose, the elaboration will be done on an existing model of aircraft with radical modifications in the wing and the electronic parts. In order to achieve all this, prototype design 3D printing of components will be done.

description: Background Evidence concerning the impact of long-term exposure to fine Particulate Matter ≤2.5 μm (PM₂.₅) on Cardio-Vascular Diseases (CVDs) for those people subject to ambient air pollution in developing countries remains relatively scant. This study assessed the relationship of 15-year PM₂.₅ exposure with cardiovascular incidence and mortality rate in Isfahan province, Iran. Methods The cohort comprised 3081 participants over 35 years old who were free of CVDs. They were selected through multi-stage cluster sampling in Isfahan, Iran. PM₂.₅ exposure was determined separately for each individual via satellite-based spatiotemporal estimates according to their residential addresses. In this context, CVD is defined as either fatal and non-fatal Acute Myocardial Infarctions (AMI) or stroke and sudden cardiac death. The incidence risk for CVD and the ensuing mortality was calculated based on the average PM₂.₅ exposure within a study period of 15 years using the Cox proportional hazards frailty model upon adjusting individual risk factors. The mean annual rate of PM2.5 and the follow-up data of each residential area were combined. Results Mean three-year PM₂.₅ exposure for the cohort was measured at 45.28 μg/m³, ranging from 20.01 to 69.80 μg/m³. The median time period for conducting necessary follow-ups was 12.3 years for the whole population. Notably, 105 cardiovascular and 241 all-cause deaths occurred among 393,786 person-months (27 and 61 per 100,000 person-months, respectively). In well-adjusted models, 10 μg/m³ increase in PM₂.₅ corresponded to a 3% increase in the incidence rate of CVDs [0.95 CI = 1.016, 1.036] (in case of p = 0.000001 per 10 μg/m³ increase in PM₂.₅, the Hazard Ratio (HR) for AMI and Ischemic Heart Disease (IHD) was 1.031 [0.95 CI = 1.005, 1.057] and 1.028 [0.95 CI = 1.017, 1.039]), respectively. No consistent association was observed between PM₂.₅ concentration and fatal CVD (fatal AMI, fatal stroke, SCD (Sudden Cardiac Death)) and all-cause mortality. Conclusions Results from analyses suggest that the effect of PM₂.₅ on cardiovascular disease occurrence was stronger in the case of older people, smokers, and those with high blood pressure and diabetes. The final results revealed that long-term exposure to ambient PM₂.₅ with high concentrations positively correlated with IHD incidence and its major subtypes, except for mortality. The outcome accentuates the need for better air quality in many countries.

description: At the time of writing, the media is full of speculation about the National Broadband Network (NBN), but there is limited hard information available. This article is an attempt to tease out a better understanding of the current developments in telecommunications in Australia. It is a high-level summary of the elements being considered and the policy issues still to be resolved, from the perspective of one interested observer, and as such it is certain to need correction and clarification as more is revealed. The terminology used in this paper is that given in the appendix, which provides a short tutorial on the current telecommunications environment.

description: This presentation is an overview of archival research I have performed focusing on the student experience and response to the closure of the Urban Information Specialist Program (UISP) at the University of Maryland's School of Library and Information Service (SLIS). The UISP was developed by Mary Lee Bundy and lead by James Welbourne, and was designed to recruit lower income students, especially African Americans, to serve as librarians in lower-income communities. The UISP was an experimental program that remove barriers to access a Masters in Library Science, but the end of the program was controversial and resulted in at least one campus protest and Bundy & Welbourne published a book arguing that the university cut the program purely out of racist hatred. This presentation provides an overview of the program and discusses some of my findings in the Bibliophile (the SLIS's student newspaper) and the Diamondback.

description: Traditional multi-agent path finding (MAPF) methods try to compute entire start-goal paths which are collision free. However, computing an entire path can take too long for MAPF systems where agents need to replan fast. Methods that address this typically employ a "windowed" approach and only try to find collision free paths for a small windowed timestep horizon. This adaptation comes at the cost of incompleteness; all current windowed approaches can become stuck in deadlock or livelock. Our main contribution is to introduce our framework, WinC-MAPF, for Windowed MAPF that enables completeness. Our framework uses heuristic update insights from single-agent real-time heuristic search algorithms as well as agent independence ideas from MAPF algorithms. We also develop Single-Step CBS (SS-CBS), an instantiation of this framework using a novel modification to CBS. We show how SS-CBS, which only plans a single step and updates heuristics, can effectively solve tough scenarios where existing windowed approaches fail.

description: This study assessed the prevalence and predictors of not eating lunch on school days among Canadian children using dietary data from the 2015 Canadian Community Health Survey- Nutrition (n = 2,991 children aged 6–17 years). On a given school day, more than 1 in 20 students reported eating no lunch. Students were more likely to miss lunch if they were older, lived in a food insecure household, or smoked. Sex, ethnicity, income and weight status were not associated with lunch consumption. Future research is needed to fully understand the frequency, causes and consequences of missing lunch on school days in Canada.
Final Report on the National Geographic Society: Archaeology of Town Planning in Annapolis, Maryland, NGS Grant Number 3116-85

description: The purpose of the research supported by this grant was to refine our understanding of the Baroque town plan of Annapolis, Maryland through archaeology. The plan of 1695, which was prepared under the supervision of Royal Governor Francis Nicholson, has long been considered one of the most sophisticated and best preserved town plans in Colonial North America (Figure1). The town plan is well understood synchronically through the work of a number of scholars, but the plan was less well understood in terms cf its gradual development and alteration over the almost three centuries since it was laid down. Therefore, a primary goal of our work was the initiation of a diachronic understanding of town planning in Annapolis. Further, while the joint Historic Annapolis/ University of Maryland, College Park program called "Archaeology in Annapolis;" had established that a large part of the archaeological record of Annapolis was intact, no one knew how much of the original and subsequent street patterns could be recovered archaeologically, nor exactly how one could go about that. Therefore, the second aspect of this project was to establish a set of methods to document street and lot borders. Such a project was urgent since the city of Annapolis plans to dig trenches throughout the core of the Nicholson Plan to bury utility wires. Among other things, these utility trenches provided an opportunity to understand how the third dimension of a Baroque town plan, depth, was handled. This work will allow us to see how the plan was used through time to structure activities and in turn how it was altered to better suit them.

description: To determine the history of a given piece of property during the last quarter of the eighteenth century, look at the map facing this page. Find the city block that maintains the property in question. The number in smaller type, usually in the center of the block, is the parcel number. For example, if you were interested in a piece of property in the block bounded by Church, Duke of Gloucester, and Conduit Streets, the parcel number would be 11. Once the parcel number has been determined, tum to that number in the text, where you will find a xerox copy of a more detailed map covering that parcel. Lines have been drawn indicating the approximate boundaries of the land as it was held in 1783, and in some cases, after 1783.
Calvert Interim Report 1: Preliminary Analysis of Features from Period 1 Associated with Posthole Building(s) at Calvert Site, Annapolis, Maryland
Creators: name: Yentsch, Anne

description: This is the first of a series of interim reports being prepared on the Calvert Site. As interim reports, their objects are twofold: (1) To provide detailed information, in preliminary form, on particular aspects of the analysis of material from the Calvert Site to staff members at Historic Annapolis, Inc. (including those who may not be familiar with the methods, theories, and findings of historical archaeology.) (2) To summarize what is known to date and hence to serve as planning documents for and, in some cases, preliminary manuscripts of chapters that will be included in the final report on the Calvert Site. This report summarizes what is known to date about the late 17th/early 18th century posthole features that were found. These are among the earliest evidence of construction that we have been able to identify in the archaeological record for the site and within the town as a whole; they may predate the c. 1690-1720 brick house, the first story front and side walls plus remnants of the back (east) wall of which still remain intact in the fabric of the present standing structure (ie., the Governor Calvert House Hotel). There are no extant remains of any posthole building(s) contained within the Governor Calvert House Hotel as these were dismantled in the 18th century. This posthole building(s) may have been built as early as 1680-90 or as late as c. 1710 as there is archaeological evidence of use of the site beginning c. 1680, but documentary research to date has not revealed the chain of ownership in the 17th century.

description: Zooarchaeological evidence from the Calvert House, Annapolis, is compared to that from several southern Atlantic coastal plain sites. Although all sites are located in estuarine settings, less evidence for the use of seafood is found at either Governor Calvert's house or at urban sites on the southern coastal plain than at rural sites from the sea islands near Charleston. In other respects, the southern coastal plain data and data from the Calvert site are not similar. This may be related to the elite social status of the Calvert Household as well as to environmental differences between the Mid-Atlantic and the southern region. Finally, the evidence from these Atlantic coast sites are compared to data from 18th century plantations in Jamaica in order to underscore the observation that early English subsistence in the New World was diverse and exhibited regional variation.

Mormon Ecclesiastical Courts

description: Mormonism is a particular example of 19th century utopias. Every utopia attempted to set up a new way of life for its adherents, Some, like the Mormons, were fundamentally religious and set out the totality of a new way of life through religious precepts. To bring that way of life into existence it was often necessary to remove the group of faithful to a new locale distant from the dominant society. In so doing, progressive removal in space and contact often meant removal from the system of civil government that was part of territorial, state and federal governments. On one side, that tended to be regarded as a threat to legally established regimes, but on the other usually it meant that a system of dealing with disputes arising within the new community had to be established. So it was also with the Mormons who settled in the Great Basin in 1847, just as Utah was being incorporated as a territory into the Union. There was no civil government of ant form, let alone statutory law and a way of implementing it.
