Revisiting a Historic Manuscript: Vere Huddleston’s Report on East Place (3CL21) Excavations

Vere L. Huddleston was one of several amateur archaeologists who excavated Caddo sites in Clark County, Arkansas, during the 1930s and 1940s. Huddleston took better notes about the sites and contexts of his finds than many of his contemporaries. His large collection of artifacts is now part of the Joint Educational Consortium’s Hodges Collection in Arkadelphia. A manuscript on his excavations at the East Place – the largest Caddo mound group in Clark County – is presented here with new vessel documentation and grave lot information. Since many of these artifacts have appeared in previous publications with little description, this work provides context for interpreting the site and its placement in the Caddo Indian history of this region

On the pulse of change: the new beat of special education in higher education

The roles and responsibilities of special educators in both special and regular school settings are changing rapidly. More than two decades ago the move towards more inclusive practices disrupted the traditional, niche separatism of special educators to the extent that they are now an integral part of the regular school teaching staff. Today the broad agenda to facilitate access and participation for all students in education, not just students with disabilities, influences the roles and responsibilities of special educators. This article briefly identifies some of the generic pulses that are moving the special education profession from a focus on low incidence disabilities towards a more comprehensive approach to inclusion, school responsiveness and individualised learning pathways. From the foundation of inclusive practice, this paper will describe how a qualitative study was used to understand the changing roles and responsibilities of special educators. A case study analysis of 17 schools formed the basis of the investigation. Principals, lead teachers in special education and special education teachers were asked to identify trends and priorities in special education and also to identify rewards and challenges in their jobs. Further cross referencing with teacher and special educator standards, a focus group, a stakeholder group and research in the field increased the opportunity for academics and special educators to critically reflect on the emerging demands placed on special educators and the attributes that are needed to be professionally effective

LARCMACS: A TEX macro set for typesetting NASA reports

This LARCMACS user's manual describes the February 1988 version of LARCMACS, the TEX macro set used by the Technical Editing Branch (TEB) at NASA Langley Research Center. These macros were developed by the authors to facilitate the typesetting of NASA formal reports. They are also useful, however, for informal NASA reports and other technical documents such as meeting papers. LARCMACS are distributed by TEB for the convenience of the Langley TEX user community. LARCMACS contain macros for obtaining the standard double-column format for NASA reports, for typesetting tables in the ruled format traditional in NASA reports, and for typesetting difficult mathematical expressions. Each macro is described and numerous examples are included. Definitions of the LARCMACS macros are also included

Aloe vera: A Multipurpose Healer and Bacterial Eradicator

The Aloe vera plant is a succulent known for its rich content in vitamins and minerals, thus gaining popularity over the years in healthcare products. With advancements in alternative medicine, it has been recently found useful in dentistry due to properties such as anti-inflammatory, antioxidant and antimicrobial actions that contribute to wound healing. The purpose of this study was to examine and discover how Aloe vera can be used as an alternative therapy in the dental field. The PubMed, Google Scholar and Dentistry & Oral Sciences (DOSS) databases were utilized to find current scientific evidence on the effects of Aloe vera. Relevant articles were summarized to write a review of findings. In this study, 21 articles published from 2015 to present were reviewed. From the studies, there is strong evidence to support that Aloe vera exhibits beneficial effects in prevention of carious lesions, non-surgical scaling and root planing in patients with chronic periodontitis, and oral wounds. Furthermore, it is cost effective and easily accessible. This review’s findings indicate that dental health care providers could recommend Aloe vera as a preventive and an alternative treatment option to improve patients’ oral health status.https://scholarscompass.vcu.edu/denh_student/1005/thumbnail.jp

Change in organisations : identifying sources of resistance to change and exploring the impact of the consultancy process used

The aim of this research is to identify sources of resistance to change in organisations and to explore the impact of the consultancy process used to bring about change through the authority structures of organisations.The research was conducted using a process consultancy model with a focus on the process of how to bring about change rather than what the change will be. The model is based on an action research method and applies principles from psychoanalytic and systems theory. The guiding theory for the research was that a psychological source of resistance to change is that people use the social system in organisations as a defence against anxiety (Jaques, 1955, Menzies, 1959, Miller & Gwynne, 1972). The first research case study involved a group of employees in the National Health Service (NHS). Evidence from the cases study was used to identify conscious and unconscious sources of resistance to change and to build on the guiding theory that the social system was used as a defence against anxiety. It emerged that there were four different ways that people responded to change, which ranged from a `sycophant' to a `saboteur' response. People also had different levels of learning during change, ranging from `resistant to learning' to `internalised learning'. There was evidence that the existential primary task, i. e. the meaning that people have in their work life, can be a source of resistance to change. Two new working hypotheses were subsequently developed from these findings, which were explored further in a Bank case study. These are firstly that the existential primary task can also be a source of resistance to change and secondly that the process consultancy model can help to a) identify and understand how people respond to change; b) identify situations when the existential primary task can be a source of resistance; and c) develop people to reach a level of internalised learning. These working hypotheses were developed further based on the findings from both case studies. The conclusion is that the social defence system and the existential primary task can both be psychological sources of resistance to change. Two models were developed from the findings. One to represent a Continuum of Responses to Change and the other to represent the Dimensions of Responses to Change, which relates to an individual's capacity for personal change, their level of support for change and their response. Finally, the application of these conclusions to develop the process consultancy model and ideas for further research are discussed

Metabolism in myocardial ischaemia and reperfusion with specific reference to the role of glucose

Hypothesis: Glucose is known to be protective in moderate low flow ischaemia due to the production of glycolytic ATP. However, it is questioned whether glucose would still be protective in ultra-low flow ischaemia. Firstly, glycolysis is thought to be inhibited, and secondly, deleterious glycolytic metabolites accumulate. Our hypothesis was that in ultra-low flow ischaemia, glucose utilisation is not inhibited at the level of glycolysis, but by delivery. Increased delivery of glucose should result in increased production of protective glycolytic ATP, but the rate of metabolite accumulation would also increase. Using ultra low flow rates, I wished to investigate how to achieve optimal rates of glycolysis, and how such rates would be balanced by any detrimental component of metabolite accumulation. Methods: The isolated Langendorff-perfused rat heart, with a left ventricular balloon to record ischaemic contracture and reperfusion stunning, was used, with severe flow restriction. Glucose concentrations were changed and pre-ischaemic glycogen contents were altered by perfusion with different substrates (acetate - depletion~ glucose + insulin - loading) or by preconditioning, with 5 min ischaemia and 5 min reperfusion prior to sustained ischaemia. Results: Analysis of glucose uptake relative to delivery showed that in severe low flow ischaemia, the extraction of glucose was increased, and glycolysis was thus limited more by substrate supply than by enzyme inhibition. Analysis of metabolites confirmed this concept. The optimal glucose concentration during severe low flow ischaemia was 11 mM, giving maximal recovery on reperfusion. Both lower and higher glucose concentrations increased ischaemic contracture. Changes in pre-ischaemic glycogen levels correlated with the time to onset of contracture, such that a reduction in glycogen accelerated contracture. Prior glycogen depletion or loading did not improve functional recovery. The benefits of preconditioning on reperfusion function following sustained total global ischaemia could not be related to glycogen depletion. If preconditioning were followed by sustained low flow ischaemia, glucose uptake was increased, but no benefit was found, possibly because a low residual flow abolished the effects of preconditioning. Many of the above results are consistent with the hypothesis that too low a rate of glycolysis results. in insufficient ATP production for protection, while excess glycolytic rates lead to excess metabolite accumulation with detrimental effects. Conclusions: Provision of glucose at the correct concentration, when the benefit associated with glycolytic ATP outweighs the detriment associated with moderate metabolite accumulation, is protective to the low-flow ischaemic myocardium, which can upregulate its ability to extract glucose. Improved residual flow enhances this benefit. Prior glycogen depletion is not beneficial, despite a reduced metabolite accumulation. This mechanism cannot be related to the protective effect of preconditioning
