VIABILITY OF TIME-MEMORY TRADE-OFFS IN LARGE DATA SETS

The main hypothesis of this paper is whether compression performance – both hardware and software – is at, approaching, or will ever reach a point where real-time compression of cached data in large data sets will be viable to improve hit ratios and overall throughput. The problem identified is: storage access is unable to keep up with application and user demands, and cache (RAM) is too small to contain full data sets. A literature review of several existing techniques discusses how storage IO is reduced or optimized to maximize the available performance of the storage medium. However, none of the techniques discovered preclude, or are mutually exclusive with, the hypothesis proposed herein. The methodology includes gauging three popular compressors which meet the criteria for viability: zlib, lz4, and zstd. Common storage devices are also benchmarked to establish costs for both IO and compression operations to help build charts and discover break-even points under various circumstances. The results indicate that modern CISC processors and compressors are already approaching tradeoff viability, and that FPGA and ASIC could potentially reduce all overhead by pipelining compression – nearly eliminating the cost portion of the tradeoff, leaving mostly benefit

Brief Consultation to Families of Treatment Refusers with Symptoms of Obsessive Compulsive Disorder: Does It Impact Family Accommodation and Quality of Life?

Family members are often directly and significantly impacted by the restrictive demands of OCD, a frequently disabling disorder. Family accommodation behaviors (i.e., doing things for or because of the OCD sufferer that a person would not normally do) are associated with dysfunction, including poorer treatment responses in OCD sufferers and greater distress in family members. Although evidence suggests family-based intervention can reduce symptoms in OCD sufferers who participate in treatment, there is a lack of research documenting the impact of interventions designed for the families of OCD treatment refusers (TR). Brief Family Consultation (BFC) was developed by our clinical team to help families refocus their efforts on the things that they can realistically control and change (e.g., participation in compulsions). In this crossover study, twenty families related to an individual who exhibited OCD symptoms but had refused treatment were assigned to five phone sessions of either BFC or a psychoeducation condition. Compared to this credible, attention-placebo control group (Brief Educational Support; BES), BFC (but not BES) resulted in reductions in family accommodation behavior, yet neither BFC nor BES resulted in improved quality of life for family members of treatment refusers. BFC is one of the first interventions to be evaluated for its ability to help families when their loved ones with obsessive compulsive symptoms refuse treatment. This pilot study provides new insights for clinicians and researchers to better address the needs of these neglected families

Short-term operating plan for farms and ranches

stats082022upload"Timely decision making is essential for farm and ranch businesses. Decisions are a part of daily operations and vary greatly from prioritizing tasks to choosing inputs and deciding how much product to sell at a certain price. Most operations have primary decision makers who routinely make these decisions. It is important however, that others know how to proceed if the key decision maker(s) is/are unable to make decisions. This plan was developed to help farm and ranch families continue operating their businesses with minimal interruptions should the primary decision maker(s) be unable to make short-term decisions. The plan could be helpful in an unexpected situation such as hospitalization or military deployment."--Page 1.Mary Sobba (Field Specialist, Agricultural Business and Policy), Joni Harper (Community Engagement Specialist, Agriculture and Environment), Catherine Neuner (Community Engagement Specialist, Agriculture and Environment), Kyle Whittaker (Community Engagement Specialist, Agriculture and Environment

The purpose is to have organized information for family members to use to continue operating the farm or ranch business.

Climate change, society, and pandemic disease in Roman Italy between 200 BCE and 600 CE

Records of past societies confronted with natural climate change can illuminate social responses to environmental stress and environment-disease connections, especially when locally constrained high-temporal resolution paleoclimate reconstructions are available. We present a temperature and precipitation reconstruction for ~200 BCE to ~600 CE, from a southern Italian marine sedimentary archive-the first high-resolution (~3 years) climate record from the heartland of the Roman Empire, stretching from the so-called Roman Climate Optimum to the Late Antique Little Ice Age. We document phases of instability and cooling from ~100 CE onward but more notably after ~130 CE. Pronounced cold phases between ~160 to 180 CE, ~245 to 275 CE, and after ~530 CE associate with pandemic disease, suggesting that climate stress interacted with social and biological variables. The importance of environment-disease dynamics in past civilizations underscores the need to incorporate health in risk assessments of climate change

Climate Change during and after the Roman Empire: Reconstructing the Past from Scientific and Historical Evidence

Growing scientific evidence from modern climate science is loaded with implications for the environmental history of the Roman Empire and its successor societies. The written and archaeological evidence, although richer than commonly realized, is unevenly distributed over time and space. A first synthesis of what the written records and multiple natural archives (multi-proxy data) indicate about climate change and variability across western Eurasia from c. 100 b.c. to 800 a.d. confirms that the Roman Empire rose during a period of stable and favorable climatic conditions, which deteriorated during the Empire's third-century crisis. A second, briefer period of favorable conditions coincided with the Empire's recovery in the fourth century; regional differences in climate conditions parallel the diverging fates of the eastern and western Empires in subsequent centuries. Climate conditions beyond the Empire's boundaries also played an important role by affecting food production in the Nile valley, and by encouraging two major migrations and invasions of pastoral peoples from Central Asia.Earth and Planetary SciencesHistor

Effects of student-led drama on nursing students' attitudes to interprofessional working and nursing advocacy: A pre-test post-test educational intervention study

This is the final version. Available from Elsevier via the DOI in this record. Background: Nursing educators need to equip students to work in interprofessional teams and advocate for patients in increasingly integrated health and social care settings. Drama-based education has been used in nursing to help students understand complex concepts and practices, including communication, empathy, and patient safety. However, few studies have evaluated drama-based education to promote understanding of interprofessional care and advocacy, and none have involved student-led drama where students create dramatic performances to support learning. Objectives: To examine the effects of student-led drama on student nurses’ attitudes to interprofessional working and advocacy. Design: Pre-test post-test educational intervention study. Settings: Public university in Scotland. Participants: 400 undergraduate student nurses enrolled on a 15-week module focussed on health and social care integration and interprofessional working. Methods: Students completed paper questionnaires at the start (n = 274, response rate: 80.1 %) and end (n = 175, 63.9 %) of the module. Outcome measures were the validated Attitudes Towards Healthcare Teams Scale (ATHCTS) and Protective Nursing Advocacy Scale (PNAS). Change in mean ATHCTS and PNAS scores were assessed using paired samples t-tests, with Cohen’s d to estimate effect size. Results: ATHCTS scores significantly increased from 3.87 to 4.19 (p < 0.001, d = 0.52). PNAS scores increased from 3.58 to 3.81 (p < 0.001, d = 0.79), with significant improvements in the ‘acting as an advocate’ (4.18 to 4.51, p < 0.001, d = 0.81) and ‘environmental and educational influences’ subscales (3.79 to 4.13, p < 0.001, d = 0.75). Statements focussed on promoting holistic, dignified care and enabling health professionals to be responsive to emotional and financial needs of patients, showed greatest change. Conclusions: Education based on plays created and performed by student nurses led to significant improvements in student nurses’ attitudes towards interprofessional working and nursing advocacy. Student-led drama should be embedded in nursing curricula to enable students to understand the realities and complexities of health and social care integration and interprofessional workingEconomic and Social Research CouncilEdinburgh Napier Universit
