An Examination of Six “Nutting Stones” from East Texas for Plant Phytoliths

In this article we report on an examination of six nutting stones from East Texas sites as well as an exploratory examination of their possible functions. “Nutting stones” have long been presumed to have been used prehistorically for crushing nuts such as hickory, etc. as foodstuffs. In fact Davis described them as being: A small flat stone, usually made of limestone, sandstone or other sedimentary types of rock which could be carried by hand. The flat surface may have one or more ground or pecked cups of various sizes, shapes and depth. It is postulated that they were used for various purposes such as cracking nuts, mixing pigments, milling herbs and seeds, or as an anvil for flint knapping. While Davis is an avocationalist and numerous professional archaeologists have dealt with nutting stones, we know of neither a more complete definition nor any other effort to empirically test for their function

The impact of supply chain complexity on manufacturing plant performance

This paper puts forth a model of supply chain complexity and empirically tests it using plant-level data from 209 plants across seven countries. The results show that upstream complexity, internal manufacturing complexity, and downstream complexity all have a negative impact on manufacturing plant performance. Furthermore, supply chain characteristics that drive dynamic complexity are shown to have a greater impact on performance than those that drive only detail complexity. In addition to providing a definition and empirical test of supply chain complexity, the study serves to link the systems complexity literature to the prescriptions found in the flexibility and lean production literatures. Finally, this research establishes a base from which to extend previous work linking operations strategy to organization design [Flynn, B.B., Flynn, E.J., 1999. Information-processing alternatives for coping with manufacturing environment complexity. Decision Sciences 30 (4), 1021–1052]

Introducing an Eating Disorder Protocol in the Pediatric Primary Care Setting

Background: The incidence of eating disorders has been on the rise, often beginning in adolescence and continuing well into adulthood. Consequences of untreated disrupted eating patterns can affect multiple body systems and are responsible for thousands of deaths annually. Despite these facts, research and data regarding eating disorders in adolescent patients are severely deficient. There is also a lack of standardization regarding assessing eating disorders in the pediatric primary care setting, as there are no specific guidelines or screening processes recommended by the American Academy of Pediatrics for the detection of eating disorders. Purpose: The purpose of this project is to pilot an eating disorder protocol to a pediatric primary care clinic in Jasper, Indiana. The target population for this project were adolescents ages 12-17 years presenting for routine wellness exams. Design: A quasi-experimental design was used for this project to evaluate interventions. Methods: A pretest-posttest quasi-experimental design was used to evaluate intervention strategies’ impact on eating disorder screening rates in the pediatric primary care setting. A 4-week retrospective chart review was conducted prior to implementing the eating disorder protocol. The protocol consisted of administrating the EDE-QS to all patients 12 to 17 years of age who presented for a wellness examination. The protocol also included education to participating providers, which consisted of eating disorder significance, consequences, the importance and current data that exists in favor of routine screening, treatment recommendations set forth by the American Academy of Pediatrics, and resources for further information. Current practices in relation to referrals were utilized, including psychiatrists and counselors, nutritionists and dieticians, feeding clinics, and inpatient treatment at outside facilities. A 4-week prospective chart review was conducted to understand the change in screening rates and the prevalence of eating disorder behaviors among this age group. Data was analyzed using Pearson’s Correlation Coefficient to discover strengths of relationships between patient responses and age, as well as patient responses and BMI. Results: Zero patients out of 37 were screened in the retrospective chart review. Twenty patients were screened using the EDE-QS in the 4-week prospective review. Nine responded with a score of 0, while 11 scored with a 1 or higher. The overall mean score was 3.45. Five patients scored above the EDE-Q mean global score of 1.4 and five patients reported behaviors specific for eating disorder behaviors. The Weight Concern subscale yielded the highest scores, with all 11 patients who responded with a 1 or greater on the EDE-QS revealing some degree of weight concern, despite majority of participants being considered “healthy weight,” per their BMI. There were positive correlations between age and EDE-QS scores and BMI and EDE-QS scores, but relationships were weak (p=.653, p=.698 respectively) and not clinically significant given sample size and other limitations. Conclusion: The EDE-QS has proven to have the potential to be a useful tool in the primary care setting, as it is brief and requires a shorter recall from patients when compared to other versions. There were no clinically significant patterns or trends in data to suggest that patients with specific demographics are at risk due to limited sample size and lack of diversity. Further research is needed for accurate conclusions to be made regarding eating disorders in adolescents

Eldre65: Creating a Website for Senior Adults Based Upon User Experience

Geoffrey Chaucer wrote, “Time and tide wait for no man.” He was correct. Aging is universal. It affects all humans in positive and negative ways. From children becoming teens to adults becoming senior adults, each stage of life brings changes and challenges. In one’s forties, menus can become harder to read, hair can fall out, hearing in loud environments can become difficult. Then, in one’s mid-sixties, more difficult challenges can arrive. Health issues such as high blood pressure, diabetes, lung disease can become a regular part of one’s life. Cognition slowness, vision and hearing loss can create difficulties not only in interacting in social settings, but also managing one’s life online. Technology develops and expands constantly. Professor Peter-Paul Verbeek, distinguished Professor of Philosophy of Technology at the Department of Philosophy of the University of Twente, examined how technology, in its purest form, should be a form of mediation for its users. Technology should not be the focus, it should be the median by which you relate to the world around you. “The central idea in mediation theory is that technologies do not simply create connections between users and their environment, but that they actively help to constitute them” (Verbeek). Technology influences the way the user sees the world around them. When made usable, technology can present large positives in an individual’s life. Technology can allow a viewer who is quarantined at home the opportunity to explore a new country. Technology can also bring shopping and banking to your fingertips. It can give the immobile user the freedom to be self-reliant. Medicine, food, and cleaning needs can all be purchased using many different technologies. A user can refill medications using a finger on a smart phone, smart watch, tablet, or computer. Or they can simply use their voice on technologies like Alexa, Echo, and Siri. Technology makes these possibilities endless. But for technology to do all these wonderful things, it needs to be designed and developed in a way that does not leave certain users behind. There must be a standard that designers follow to keep technology, specifically websites, usable and accessible to all. User inclusivity is the most important component that technology needs to focus upon, and where it is falling the most behind. If the user cannot see the words on the screen, hear a video on a site, or understand how to navigate through pages, then technology and all the wonderful things it can do are useless

Environmental Liens and Title Insurance

Increased concern for the environment and environmental protection laws have affected title insurance. To understand this effect, it is necessary to examine our environmental problems, the environmental laws and the nature of title insurance. This article also looks at the title insurance industry\u27s reaction to these environmental risks as compared to the reaction of the property/casualty insurance industry

The Effect of Grade Level, Achievement, and Type of Task on Metacognitive Awareness in Elementary Mathematics

Metacognition is an awareness of how one thinks and learns. It includes an awareness of the strategies used to learn as well as an awareness of oneself as a learner. The purpose of this study was to describe children's metacognitive awareness during a classroom type task. A further purpose was to determine how grade level, achievement, and type of task influence this awareness. One hundred sixty-eight fourth, sixth, and eighth grade boys and girls were classified as high or low math achievers based on their performance on the Comprehensive Test of Basic Skills, a group achievement test. These children were then randomly selected to receive either known or unknown math problems. The known math task was operationally defined as one that was easy; it was a problem that the children would be able to solve. The unknown task was operationally defined as one that was difficult, it was a math problem that these children would find unsolvable. lmmediately following the task, the children were given feedback about their performance and were then asked to identify types of thoughts they may have had as they were working on the problems. The types of thoughts included general and specific strategies as well as ability and effort self-evaluations. A 3 x 2 x 2 factorial analysis of variance design was used with Grade Level (four, six, and eight), Achievement (high and low), and Type of Task (known and unknown) as the between subjects factors. Findings showed that a known task elicited positive ability and effort self-evaluations for success. An unknown task evoked the use of more specific strategies than a known task. A grade level difference in metacognitive awareness showed that young children reported more metacognitive thoughts than older children

Statistical Study of the Effect of Implementing an Airveyor System on the Warpage of Injection Molded Closures

Berry Global in Bowling Green, Kentucky produces predominantly polypropylene container closures. One variant, the 83mm lined jar closure, is produced by first being injection molded, placed in work-in-progress (WIP) hold for 24 hours to cool, and then finished through the auxiliary liner operation into a final product. While this process is an effective method to produce a quality large-diameter closure and allows the polypropylene adequate time to cool without warping out of shape, the 24-hour WIP time and the manpower needed to accomplish this can negatively impact several business metrics as well as employee safety. The purpose of this thesis was to document the application of Six Sigma to improve the process of manufacturing 83mm lined jar closures. This was completed by executing the define, measure, analyze, improve, and control (DMAIC) process at the heart of Six Sigma to define the process, measure current WIP and desired airveyor continuous flow process metrics to analyze any impact to the closure, and put controls in place to ensure the improved process was stable. The project resulted in a successful application of the Six Sigma methodology and positive variable data results supporting a recommendation for the change to a continuous flow airveyor process
