Assessment of Non-Indexed Open Access Journals Impact
The journal impact factor remains a controversial metric and its widespread adoption has critical implications for the development of open access journals not indexed by the Web of Science. The present study evolved from collaborations with editors of a small open-access locally published social sciences journal to assess its global reach and research value according to the professed scope and mission of the journal. Using a combination of Google Scholar and BePress data, we built a customized multifaceted framework to measure the success of this journal beyond citation counts. Our analysis incorporated the bibliometric concepts of popularity and prestige, as well as measures of readership and global reach in order to quantify the journal\u27s impact for prospective contributors. This poster will highlight the issues and benefits of using various types of data available to assess the impact of a journal
Engaging Faculty and Students through Collection Assessment
How do faculty and graduate students provide input for collection development? How well have librarians understood the research needs of recently tenured faculty or recent graduates? Four librarians from four different collection areas- the humanities, the social sciences, and 2 unique areas in engineering- all set out to see if evaluating the collection against recent publications by faculty and students can foster stronger engagement between them and the subject collectors in their areas
mcLARO: Multi-Contrast Learned Acquisition and Reconstruction Optimization for simultaneous quantitative multi-parametric mapping
Purpose: To develop a method for rapid sub-millimeter T1, T2, T2* and QSM
mapping in a single scan using multi-contrast Learned Acquisition and
Reconstruction Optimization (mcLARO).
Methods: A pulse sequence was developed by interleaving inversion recovery
and T2 magnetization preparations and single-echo and multi-echo gradient echo
acquisitions, which sensitized k-space data to T1, T2, T2* and magnetic
susceptibility. The proposed mcLARO used a deep learning framework to optimize
both the multi-contrast k-space under-sampling pattern and the image
reconstruction based on image feature fusion. The proposed mcLARO method with
R=8 under-sampling was validated in a retrospective ablation study using fully
sampled data as reference and evaluated in a prospective study using separately
acquired conventionally sampled quantitative maps as reference standard.
Results: The retrospective ablation study showed improved image sharpness of
mcLARO compared to the baseline network without multi-contrast sampling pattern
optimization or image feature fusion, and negligible bias and narrow 95% limits
of agreement on regional T1, T2, T2* and QSM values were obtained by the
under-sampled reconstructions compared to the fully sampled reconstruction. The
prospective study showed small or negligible bias and narrow 95% limits of
agreement on regional T1, T2, T2* and QSM values by mcLARO (5:39 mins) compared
to reference scans (40:03 mins in total).
Conclusion: mcLARO enabled fast sub-millimeter T1, T2, T2* and QSM mapping in
a single scan
The role of assistance dogs in society
Assistance dogs are specially trained to undertake a variety of tasks to help individuals with disabilities. This review gives an overview of the different types of assistance dogs in the UK, including guide dogs, hearing dogs, mobility assistance dogs, service dogs and dual purpose dogs. The literature describes many benefits of assistance dogs, including their impact on physical wellbeing and safety of their ‘owners,’ as well as on psychological wellbeing and social inclusion. The role of assistance dogs in society is widely recognized by the public, but is not currently acknowledged in government social policy. The current evidence on the benefits of assistance dogs is limited by the type and scale of current research. This article highlights the need for independent funding for high quality research to enable social care and policy makers to make evidence-based decisions on the value of assistance dogs to people with disabilities
A shared frequency set between the historical mid-latitude aurora records and the global surface temperature
Herein we show that the historical records of mid-latitude auroras from 1700
to 1966 present oscillations with periods of about 9, 10-11, 20-21, 30 and 60
years. The same frequencies are found in proxy and instrumental global surface
temperature records since 1650 and 1850, respectively and in several planetary
and solar records. Thus, the aurora records reveal a physical link between
climate change and astronomical oscillations. Likely, there exists a modulation
of the cosmic ray flux reaching the Earth and/or of the electric properties of
the ionosphere. The latter, in turn, have the potentiality of modulating the
global cloud cover that ultimately drives the climate oscillations through
albedo oscillations. In particular, a quasi 60-year large cycle is quite
evident since 1650 in all climate and astronomical records herein studied,
which also include an historical record of meteorite fall in China from 619 to
1943. These findings support the thesis that climate oscillations have an
astronomical origin. We show that a harmonic constituent model based on the
major astronomical frequencies revealed in the aurora records is able to
forecast with a reasonable accuracy the decadal and multidecadal temperature
oscillations from 1950 to 2010 using the temperature data before 1950, and vice
versa. The existence of a natural 60-year modulation of the global surface
temperature induced by astronomical mechanisms, by alone, would imply that at
least 60-70% of the warming observed since 1970 has been naturally induced.
Moreover, the climate may stay approximately stable during the next decades
because the 60-year cycle has entered in its cooling phase.Comment: 18 pages, 11 figure
Clinical evaluation of atypical glandular cells of undetermined significance upon cervical cytologic examination in Israeli Jewish women
Atypical glandular cells in conventional cervical smears: Incidence and follow-up
BACKGROUND: Atypical glandular cells on cervical smears are often associated with clinically significant uterine lesions. The frequency and accuracy of AGC-NOS (i.e. atypical glandular cells, not otherwise specified) diagnoses, regardless of the gland cell type or the degree of suspicion, and their outcome were investigated. METHODS: From January 1, 1990 to December 31, 1999 a total of 261 patients had an AGC-NOS diagnosis made by conventional cervical Papanicolaou smear interpretation representing 0.05% of all Pap-smears analyzed at the national level. 191 (73.2%) patients had a subsequent histological examination, 8 samples were not representative by origin and were excluded. RESULTS: Out of 183 AGC-NOS diagnosed, 56.3% (103/183) were associated with tissue-proven precancerous and/or cancerous lesions, 44% being of endocervical and 56% of endometrial origin. 75% of all AGC-patients were asymptomatic. 66.7% (6/9) of the patients with subsequent invasive endocervical adenocarcinoma (AC) and 56% (28/50) of those patients with invasive endometrial AC were without clinical symptoms. 3 patients out of 9 with an invasive endocervical AC were 35 years of age or less. 10.1% and 12.3% of all 'new' tissue-proven invasive endocervical or endometrial AC respectively recorded by the national Morphologic Tumour Registry (MTR) were first identified by a cytological AGC-NOS diagnosis. CONCLUSION: Our findings emphasize the importance of the cytological AGC-category even in the absence of a precise origin or cell type specification. 56% of the AGC-diagnoses being associated with significant cancerous or precancerous conditions, a complete and careful evaluation is required
