One size does not fit all: advanced practice provider considerations for the antimicrobial steward

Advanced practice providers are a diverse and established group of antimicrobial prescribers in both ambulatory and inpatient settings. We outline important considerations for antimicrobial stewardship programs and stewards to consider when engaging this important group of providers

An investigation into E-business service in the UK telecommunication manufacturing industry

Nowadays, suppliers’ product and service quality has risen in importance with a manufacturer’s push to develop core competencies and capitalise on global operations and markets. However, due to the complex features of business service, suppliers are facing significant challenges in providing service effectively and developing business collaboration. This is further complicated by the development of information and communication technologies (ICTs). This paper thus attempts to investigate the factors influencing buyers’ e-service (EBS) requirements and the impact of these requirements on business collaboration. Based on a questionnaire survey with 500 UK telecommunication manufacturers, this research identifies buyers’ different EBS requirements for different types of suppliers and the impact of ICTs on EBS requirements. While for suppliers our findings provide insights into buyers’ EBS requirements, they can help buyers to develop appropriate supplier selection criteria. The findings also contribute to a better understanding of the development of buyer and supplier business collaboration

HIV policy: the path forward--a joint position paper of the HIV Medicine Association of the Infectious Diseases Society of America and the American College of Physicians.

Executive Summary The American College of Physicians (ACP) and the Infectious Diseases Society of America (IDSA) have jointly published 3 policy statements on AIDS, the first in 1986 [1], the second in 1988 [2], and the third in 1994 [3]. In 2001, the IDSA created the HIV Medicine Association (HIVMA), and this updated policy paper is a collaboration between the ACP and the HIVMA of the IDSA. Since the last statement, many new developments call for the need to reexamine and update our policies relating to HIV infection. First, there have been major advances in treatment for HIV infection that have transformed HIV/AIDS from a terminal illness to a chronic disease for many of those who have access to potent therapies and expert medical care [4]. Second, there has been a profound expansion and intensification of the global HIV pandemic, particularly in sub-Saharan Africa, coupled with significant US leadership and resources aimed at providing prevention and care services to affected populations in developing countries. Third, the concerns that were prevalent in the mid-1990s regarding the possibility of HIV transmission in health care settings have ultimately proven to be unfounded as the result of the adoption of universal precautions in those settings. In this article, we emphasize the public health and clinical imperatives for earlier identification of persons with HIV infection; the urgent need to expand access to state-of-the-art HIV care and treatment for infected individuals; the need for access to comprehensive prevention and education for those living with and those at risk for HIV infection; and the need for stronger national leadership to respond to the HIV epidemic in the United States and in the developing world. In December 2008, the ACP and HIVMA released a guidance statement on screening for HIV infection in health care settings that recommended that clinicians adopt routine screening for HIV infection and encourage patients to be tested. Also included in the guidance statement is a recommendation that clinicians determine the need for additional screening on an individual basis

An updated radiocarbon-based ice margin chronology for the last deglaciation of the North American Ice Sheet Complex

The North American Ice Sheet Complex (NAISC; consisting of the Laurentide, Cordilleran and Innuitian ice sheets) was the largest ice mass to repeatedly grow and decay in the Northern Hemisphere during the Quaternary. Understanding its pattern of retreat following the Last Glacial Maximum is critical for studying many facets of the Late Quaternary, including ice sheet behaviour, the evolution of Holocene landscapes, sea level, atmospheric circulation, and the peopling of the Americas. Currently, the most up-to-date and authoritative margin chronology for the entire ice sheet complex is featured in two publications (Geological Survey of Canada Open File 1574 [Dyke et al., 2003]; ‘Quaternary Glaciations – Extent and Chronology, Part II’ [Dyke, 2004]). These often-cited datasets track ice margin recession in 36 time slices spanning 18 ka to 1 ka (all ages in uncalibrated radiocarbon years) using a combination of geomorphology, stratigraphy and radiocarbon dating. However, by virtue of being over 15 years old, the ice margin chronology requires updating to reflect new work and important revisions. This paper updates the aforementioned 36 ice margin maps to reflect new data from regional studies. We also update the original radiocarbon dataset from the 2003/2004 papers with 1541 new ages to reflect work up to and including 2018. A major revision is made to the 18 ka ice margin, where Banks and Eglinton islands (once considered to be glacial refugia) are now shown to be fully glaciated. Our updated 18 ka ice sheet increased in areal extent from 17.81 to 18.37 million km2, which is an increase of 3.1% in spatial coverage of the NAISC at that time. Elsewhere, we also summarize, region-by-region, significant changes to the deglaciation sequence. This paper integrates new information provided by regional experts and radiocarbon data into the deglaciation sequence while maintaining consistency with the original ice margin positions of Dyke et al. (2003) and Dyke (2004) where new information is lacking; this is a pragmatic solution to satisfy the needs of a Quaternary research community that requires up-to-date knowledge of the pattern of ice margin recession of what was once the world’s largest ice mass. The 36 updated isochrones are available in PDF and shapefile format, together with a spreadsheet of the expanded radiocarbon dataset (n = 5195 ages) and estimates of uncertainty for each interval

Sociodramatic play of kindergarten and first grade children.

The purpose of this study was to examine the effects of modeling on the sociodramatic play of kindergarten and first grade subjects enrolled in an elementary school receiving Title I funding. One hundred and twenty-eight children selected from eight classrooms comprised the sample for the study. The children in the sample were randomly divided into eight equal cells on the basis of grade level, sex, and treatment condition. There were sixteen subjects in each cell.The experimental group subjects were exposed to four, ten minute videotapes of peers modeling sociodramatic play. These videotapes were produced and filmed by the investigator. The videotapes were filmed in the playroom, set up in the same manner as during the data collection phase of the experiment. Each of these videotapes had four different models (two male, two female). The sixteen models were selected through the use of a sociogram. Subjects in the control group viewed four, ten minute nature films, believed to have nothing to do with sociodramatic play. Treatment for both experimental and control groups took place on the four school days immediately preceding data collection.The sociodramatic play of each subject was rated during three, ten minute observation sessions. Thus, each subject's sociodramatic play was rated for thirty minutes. The rating was carried out by the two raters trained by the investigator. The instrument employed was the Christman, Werton, Schurr Observation Instrument, an adaptation of an instrument developed by Smilansky.- The C.W.S. Observation Instrument allowed for the recording of the frequency with which each of the six elements of sociodramatic play occurred during a ten minute observation period at thirty second intervals. The subject received a check mark for any of the elements present during each thirty second interval. The subjects were rated individually in play groups of four (two male, two female). The interrater reliability was established at .95.The data was analyzed through a multivariate analysis of variance with the six elements of sociodramatic play as the dependent variables and grade level, sex, and treatment condition as the independent variables. The following null hypotheses were tested: Hypothesis I: There is no significant difference in sociodramatic play between male and female subjects; Hypothesis II: There is no significant difference in sociodramatic play between kindergarten and first grade children and; Hypothesis III: There is no significant difference in sociodramatic play between experimental and control group subjects.While the three-way interaction was not significant (p < .25), each independent variable was involved in significant two-way interactions. This rendered the main effects uninterpretable. However, since grade level was involved in both significant two-way interactions the data was analyzed by nesting sex and treatment within grade level.There were significant differences in the sociodramatic play of kindergarten subjects due to sex, with males engaging in more sociodramatic play than females (p < .0001). The sex differences among first graders were not significant (p <.48).There were significant differences among kindergarten subjects due to treatment conditions with those exposed to peer modeling engaging in more sociodramatic play than those exposed to nature films (p < .0001). The differences due to treatment were not significant for first grade subjects (p < .43)Thesis (D. Ed.
