thesisThe lowest four members of the Koobi Fora Formation: the Lonyumun Member, the Moiti Member, the Lokochot Member, and the Tulu Bor Member, are exposed in Areas 117, 137 and 116. These deposits include strata that were incorrectly identified as the KBS Tuff and the Surgaei tuff in Findlater's 1976 study. The composite thickness of strata within the study area is approximately 170 m, approximately 100 m of which are deposits of the Lonyumun Member. In addition to these strata, intrusions of Gombe Group basalts are exposed as well as a littoral zone of the lacustrine Galana Boi Formation of Holocene age. A large lake from 4.2-3.99 Ma, a fluvial deltaic system from 3.99-3.40 and a large fluvial system from 3.40-3.06 Ma deposited strata of the Koobi Fora Formation in this region. This observation is consistent with Brown and Feibel's 1991 study. Nine tuffs are exposed in the study area. Two of these tuffs, the Naibar and Aberegaiye Tuff, are newly named in this study. The Naibar Tuff was deposited by fluvial action to the shores of the receding Lonyumun Lake

Constitution-making: The round table model, popular participation & constituent assemblies

In this paper, I will argue that the round table model is the ideal constitution making process. This is primarily because it gives clarity to the respective powers of the institutions involved in the process, and may prevent a dominant group or individual from unilaterally imposing a constitution. In building my argument, I outline the theory of constituent power and its corollaries of unlimited constitution making power and popular participation. I endeavour to portray the shortcomings of the theory itself, and, the dangers of its practical manifestation. Following this, I introduce the round table model as a preferable alternative, both theoretically and practically. To buttress my argument, I examine the Bolivian, Venezuelan, Russian and South African constitution making episodes

Comprehensive Physical Therapy Treatment Following A Surgical Repair Of A Flexor Hallucis Longus Tendon In A Skateboarder: A Case Report

Flexor Hallucis Longus (FHL) injuries occur when stress is placed on the great toe. FHL tendinopathies are common in ballet dancers, however, not often seen in skateboarders. The most effective physical therapy (PT) rehabilitation protocol for an FHL tendinopathy and subsequent repair in a skateboarding athlete has not been well documented. The purpose of this case report is to investigate a comprehensive PT protocol, including video feedback after an FHL repair in a skateboarding athlete.https://dune.une.edu/pt_studcrposter/1090/thumbnail.jp

The Crustose Brown Algae of New Zealand: a Taxonomic Study

Nine species of crustose brown algae are described from New Zealand’s coast. Three species are microthalli of species of Scytosiphonaceae: Colpomenia bullosa Yamada, Scytosiphon lomentaria (Lyngbye) Link and Petalonia binghamiae (J. Agardh) Vinogradova. One species of Lithodermataceae, Pseudolithoderma roscoffense Loiseaux is described from Northland. Four species are Ralfsiaceae, Ralfsia expansa (J. Agardh) J. Agardh, Ralfsia confusa Hollenberg, a new species, Ralfisa sp. “smooth”, and Hapalospongidion gelatinosum Saunders. H. saxigenum Lindauer is identical to Hapalospongidion gelatinosum Saunders. One new species of Diplura, currently placed in the Ralfsiaceae, is described. Ralfsia verrucosa (Areschoug) Areschoug, previously reported from New Zealand, was not found. ITS-2 sequences show that Ralfsia expansa, Ralfsia confusa and Ralfsia sp. “smooth” are closely related. Ralfsia expansa is more distantly related. These relationships are consistent with morphological differences. LSU nrDNA sequences show Diplura sp. and Pseudolithoderma roscoffense are not closely related to other Ralfsiaceae. These algae form a weakly supported group with members of the Sphacelariales. Hapalospongidion and three Ralfsia species form a well supported group, but this group’s relationship to other phaeophycean orders is not resolved. These results are discussed in relation to plastid number and the status of the order Ralfsiales

The Benefits of Socio-Rhetorical Analysis for Expository Preaching

Over the past twenty years, the field of Biblical studies has witnessed a marked increase in the interest devoted to the subject of socio-rhetorical analysis. Much of the work done one this subject reveals that it has great potential for shedding new light on the Biblical text. However, in order for this type of analysis to reach its maximum value for the church it must be integrated with the field of homiletics. Surprisingly, a review of the literature reveals that little attention has been given to showing how this type of analysis can be incorporated into the ministry expository preaching. The purpose of this project, therefore, is to propose a model for integrating socio-rhetorical analysis into the process of preparing expository sermons and demonstrating its effectiveness through a series of messages preached through the Pauline Prison Epistles at the First Baptist Church, Metropolis, IL

Impaired glucose tolerance or newly diagnosed diabetes mellitus diagnosed during admission adversely affects prognosis after myocardial infarction: An observational study

Objective To investigate the prognostic effect of newly diagnosed diabetes mellitus (NDM) and impaired glucose tolerance (IGT) post myocardial infarction (MI). Research Design and Methods Retrospective cohort study of 768 patients without preexisting diabetes mellitus post-MI at one centre in Yorkshire between November 2005 and October 2008. Patients were categorised as normal glucose tolerance (NGT n = 337), IGT (n = 279) and NDM (n = 152) on predischarge oral glucose tolerance test (OGTT). Primary end-point was the first occurrence of major adverse cardiovascular events (MACE) including cardiovascular death, non-fatal MI, severe heart failure (HF) or non-haemorrhagic stroke. Secondary end-points were all cause mortality and individual components of MACE. Results Prevalence of NGT, impaired fasting glucose (IFG), IGT and NDM changed from 90%, 6%, 0% and 4% on fasting plasma glucose (FPG) to 43%, 1%, 36% and 20% respectively after OGTT. 102 deaths from all causes (79 as first events of which 46 were cardiovascular), 95 non fatal MI, 18 HF and 9 non haemorrhagic strokes occurred during 47.2 ± 9.4 months follow up. Event free survival was lower in IGT and NDM groups. IGT (HR 1.54, 95% CI: 1.06–2.24, p = 0.024) and NDM (HR 2.15, 95% CI: 1.42–3.24, p = 0.003) independently predicted MACE free survival. IGT and NDM also independently predicted incidence of MACE. NDM but not IGT increased the risk of secondary end-points. Conclusion Presence of IGT and NDM in patients presenting post-MI, identified using OGTT, is associated with increased incidence of MACE and is associated with adverse outcomes despite adequate secondary prevention

Test and optimization of a multi-modal phase-based x-ray microscope for soft tissue imaging

Tissue imaging is a pivotal component of both biomedical research and clinical practice. In order to identify tissue structures down to the cellular level, it requires the capability to image mm-size unstained tissue specimens with micron to sub-micron resolution. Tissue imaging is normally performed either using x-rays or visible light. While the latter is limited by light scattering in relatively thick tissues, the former often suffers from poor contrast in absorption-based systems. Phase-contrast x-ray microscopes exist but they often lack the required quantitativeness, entail acquisition times of the order of tens of hours for 3-D imaging and are limited to narrow fields of view. We propose a novel multi-modal phase-based x-ray microscope capable of imaging mm-thick tissue samples on a mm-size field of view using intensity-modulation masks. They act as optical elements allowing the quantitative retrieval of tissue properties such as transmission, refraction and scattering. Additionally, given that the system’s spatial resolution depends only on the mask aperture size, a multi-resolution approach is possible by selecting masks with aperture size matching the resolution requirements (micron and sub-micron) of specific samples. The design and optimization of the x-ray microscope is presented in this paper together with exemplar images of a thin foam sample resulting from the retrieval of the three contrast channels. The final paper will include details of the system parameter optimization (e.g., propagation distance, mask aperture and period), their effect on the retrieval algorithm and imaging performance as well as the first images of biological samples

ABSTRACT

Dance games are one of the most popular types of bodycontrolled console games, making them ideal candidates for initiating exertion in players who do not exercise regularly. However, in order to become effective tools for consistent cardiovascular exercise, dance games need to maintain interest over a long time span. One solution that could help with long-term engagement is the addition of more narrative, competitive, and decorative elements. While other gameplay genres utilize this content to keep players involved, motion-controlled dance games are just beginning to incorporate these elements. We built Dance Enhanced, a website designed to offer earnable content to players of the game Dance Central 2. We conducted a four-week study comparing a group of participants playing the game alone with a group that also had access to the website. In this paper, we discuss the methodology for designing and operating this study, as well as our results, which indicated the potential for higher interest in competition, characters and storylines when presented with extra content

Self-interest And Public Interest: The Motivations Of Political Actors

Self-Interest and Public Interest in Western Politics showed that the public, politicians, and bureaucrats are often public spirited. But this does not invalidate public-choice theory. Public-choice theory is an ideal type, not a claim that self-interest explains all political behavior. Instead, public-choice theory is useful in creating rules and institutions that guard against the worst case, which would be universal self-interestedness in politics. In contrast, the public-interest hypothesis is neither a comprehensive explanation of political behavior nor a sound basis for institutional design
