Connections Between Christian Communion and the Jewish Seder

In lieu of an abstract, below is the essay\u27s first paragraph. For many years, I have been trying to find a religious faith that was right for me. During these past few years I have found Christianity to be the faith that was right for myself but did not have a full understanding as to why I felt this way. By attending the State Street United Methodist Church in Fulton, NY, I was given the opportunity to learn more about the Christian faith and the ceremonies that accompanied it. At the church, Communion ceremonies were held on the first Sunday of each month and for religious holidays. Over time, I learned that Communion ceremonies are a very large component of the Christian faith and wanted to learn more about them; hence why I chose this topic. I also wanted to compare Communion ceremonies to ceremonies in another religious faith in order to have a better understanding as to why they are practiced. Through researching the Communion ceremony I found a ceremony in the Jewish faith to be very similar, the Passover Seder. In fact, Communion is not only similar to the Passover Seder but is directly connected to that ceremony in several ways. To get the research I needed to understand the Passover Seder and Communion, I have consulted sources from various colleges, from my hometown, internet databases and conversed to other people who have had experiences with these ceremonies in the past

Who Will Lead Next: Where are the New Volunteers?

The American Society for Engineering Education (ASEE) has more than 12,000 members. The majority of ASEE members are faculty, staff and students from engineering and technology colleges and universities; librarians; STEM and K-12 educators; and corporate members, government agencies and professional societies. ASEE consists of over 50 divisions, twelve sections, four zones, and six councils. Each of these has an officer or set of officers, which lead the divisions, sections, zones or councils. This paper documents a pilot study that examines the past, present and future leaders of the Engineering Technology Division (ETD) and Engineering Technology Council (ETC). The primary goal of this research effort is to explore the various avenues and opportunities for future leadership of EDT and ETC. Past and current leaders of ETD and ETC will be surveyed to determine the factors that drive the motivation and dedication for service leadership within ASEE. The membership of ETD and ETC will be surveyed to find out what the barriers are to becoming leaders specifically in ETD and ETC. Depending on the findings of this pilot study, the authors will expand this research in a larger scope within ASEE and into other societies. Some of the questions that this research will attempt to answer are: 1.) “Do other ASEE divisions and councils encounter problems in recruiting and retaining new leaders?” and 2.) “Do other professional societies have difficulties finding volunteer leaders from academia?

“Putting on our people lens”: Lived Experience as Pedagogy

In the professional education of mental health practitioners, including occupational therapists, there has been a lack of meaningful inclusion of people labeled with mental illness into curricula, beyond guest speaker panels and presentations. This study explored the experiences of students, faculty, and ‘Experts by Experience’ within a mental health occupational therapy course that incorporated Experts with lived experience as co-facilitators of weekly fieldwork debriefs. The study utilized focus groups and interviews to understand the experiences of students, mental health faculty, and ‘Experts by Experience’. Key themes that emerged from the qualitative data analysis were organized under three broad categories: 1) Students experienced powerful insights, 2) Experts conveyed the complexity of the work, and 3) Faculty grew from co-creating learning experiences with the Experts. This research makes a significant contribution to occupational therapy education by shifting the Expert’s role beyond traditional speaker panels or storytelling. This broader responsibility elevated experiential knowledge into the realm of practice in clinical reasoning by shifting the context of the knowledge from storytelling to support practice reasoning. While this created significant learning opportunities for the students, it also did appear to cause emotional risk for the ‘Experts by Experience’. It is important that efforts to include ‘Experts by Experience’ in curriculum also include sources of support and financial remuneration

Infanticide in wolves: seasonality of mortalities and attacks at dens support evolution of territoriality

Evidence for territoriality is usually correlative or post hoc as we observe the results of past selection that are challenging to detect. Wolves (Canis lupus) are considered territorial because of competition for food (resource defense), yet they exhibit classic intrinsic behaviors of social regulation (protection against infanticide). This emphasis on prey and infrequent opportunity to observe wild wolf behavior has led to little investigation into the causes of or competitive underpinnings in the evolution of wolf territoriality. We report 6 cases of territorial wolf packs attacking neighboring packs at or near their den; 2 attacks were observed in detail. In all cases, except perhaps one, the attacking pack killed adult wolves either at the den or near it; in 4 cases, pups were probably lost. Loss of pups led to future loss of territory and in one case pack cessation. Intraspecific killing (measured in collared adults only) peaked in April, the month when pups were born and helpless in dens, even though aggressive interactions were at their seasonal low. Twelve of 13 (92%) of the wolves killed during the denning season (March, April, May) were reproductive (males and females), and 8 of 12 were dominant individuals (highest ranking wolf for that sex in the pack). Wolf–wolf killings were also high in October and December, the beginning and middle of the nomadic season, respectively. Aggressive interactions were more frequent during the nomadic season when wolves were roaming their territory as a group compared to the denning season when wolf activity was centered on the den and pack members less cohesive. We conclude that attacks on dens are a more effective form of interpack competition than interference during the breeding season, the current best-supported hypothesis, and that protected pup-rearing space is the primary cause of wolf territoriality

Quantitative diffusion tensor imaging detects dopaminergic neuronal degeneration in a murine model of Parkinson\u27s disease.

Early diagnosis of Parkinson\u27s disease (PD) is required to improve therapeutic responses. Indeed, a clinical diagnosis of resting tremor, rigidity, movement and postural deficiencies usually reflect \u3e50% loss of the nigrostriatal system in disease. In a step to address this, quantitative diffusion tensor magnetic resonance imaging (DTI) was used to assess nigrostriatal degeneration in the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) intoxication model of dopaminergic nigral degeneration. We now demonstrate increased average diffusion (p\u3c0.005) and decreased fractional anisotropy (p\u3c0.03) in the substantia nigra (SN) of 5- to 7-day MPTP-treated animals when compared to saline controls. Transverse diffusivity demonstrated the most significant differences (p \u3c or = 0.002) and correlated with the numbers of SN dopaminergic neurons (r=-0.75, p=0.012). No differences were found in the striatum, corpus callosum, cerebral cortex, or ventricles. These results demonstrate that DTI may be used as a surrogate biomarker of nigral dopaminergic neuronal degeneration

Identifying Old Tidal Dwarf Irregulars

We examine the observational consequences of the two possible origins for irregular galaxies: formation from collapse of a primordial cloud of gas early in the age of the Universe, and formation from tidal tails in an interaction that could have occured any time in the history of the Universe. Because the formation from tidal tails could have occurred a long time ago, proximity to larger galaxies is not sufficient to distinguish tidal dwarfs from traditional dwarfs. We consider the effects of little or no dark matter on rotation speeds and the Tully-Fisher relationship, the metallicity-luminosity relationship, structure, and stellar populations. From these selection criteria, we identify a small list of dwarf irregular galaxies that are candidates for having formed as tidal dwarfs.Comment: ApJ, to appear September 20, 200

The First Phylogenetic Analysis of Palpigradi (Arachnida)—The Most Enigmatic Arthropod Order

Palpigradi are a poorly understood group of delicate arachnids, often found in caves or other subterranean habitats. Concomitantly, they have been neglected from a phylogenetic point of view. Here we present the first molecular phylogeny of palpigrades based on specimens collected in different subterranean habitats, both endogean (soil) and hypogean (caves), from Australia, Africa, Europe, South America and North America. Analyses of two nuclear ribosomal genes and COI under an array of methods and homology schemes found monophyly of Palpigradi, Eukoeneniidae, and a division of Eukoeneniidae into four main clades, three of which include samples from multiple continents. This supports either ancient vicariance or long-range dispersal, two alternatives we cannot distinguish with the data at hand. In addition, we show that our results are robust to homology scheme and analytical method, encouraging further use of the markers employed in this study to continue drawing a broader picture of palpigrade relationships.Organismic and Evolutionary Biolog

Treatment of a chemoresistant neuroblastoma cell line with the antimalarial ozonide OZ513.

BACKGROUND: Evaluate the anti-tumor activity of ozonide antimalarials using a chemoresistant neuroblastoma cell line, BE (2)-c. METHODS: The activity of 12 ozonides, artemisinin, and two semisynthetic artemisinins were tested for activity against two neuroblastoma cell-lines (BE (2)-c and IMR-32) and the Ewing\u27s Sarcoma cell line A673 in an MTT viability assay. Time course data indicated that peak effect was seen 18 h after the start of treatment thus 18 h pre-treatment was used for all subsequent experiments. The most active ozonide (OZ513) was assessed in a propidium iodide cell cycle flow cytometry analysis which measured cell cycle transit and apoptosis. Metabolic effects of OZ513 in BE (2)-c cells was evaluated. Western blots for the apoptotic proteins cleaved capase-3 and cleaved PARP, the highly amplified oncogene MYCN, and the cell cycle regulator CyclinD1, were performed. These in-vitro experiments were followed by an in-vivo experiment in which NOD-scid gamma immunodeficient mice were injected subcutaneously with 1 × 10(6) BE (2)-c cells followed by immediate treatment with 50-100 mg/kg/day doses of OZ513 administered IP three times per week out to 23 days after injection of tumor. Incidence of tumor development, time to tumor development, and rate of tumor growth were assessed in DMSO treated controls (N = 6), and OZ513 treated mice (N = 5). RESULTS: It was confirmed that five commonly used chemotherapy drugs had no cytotoxic activity in BE (2)-c cells. Six of 12 ozonides tested were active in-vitro at concentrations achievable in vivo with OZ513 being most active (IC50 = 0.5 mcg/ml). OZ513 activity was confirmed in IMR-32 and A673 cells. The Ao peak on cell-cycle analysis was increased after treatment with OZ513 in a concentration dependent fashion which when coupled with results from western blot analysis which showed an increase in cleaved capase-3 and cleaved PARP supported an increase in apoptosis. There was a concentration dependent decline in the MYCN and a cyclinD1 protein indicative of anti-proliferative activity and cell cycle disruption. OXPHOS metabolism was unaffected by OZ513 treatment while glycolysis was increased. There was a significant delay in time to tumor development in mice treated with OZ513 and a decline in the rate of tumor growth. CONCLUSIONS: The antimalarial ozonide OZ513 has effective in-vitro and in-vivo activity against a pleiotropic drug resistant neuroblastoma cell-line. Treatment with OZ513 increased apoptotic markers and glycolysis with a decline in the MYCN oncogene and the cell cycle regulator cyclinD1. These effects suggest adaptation to cellular stress by mechanism which remain unclear
