Women in Public Relations (1982-2019)
Purpose
This paper aims to analyse the current literature on women in public relations to establish trends and areas of inquiry in the literature and identify research gaps for future research.
Design/methodology/approach
A total of 223 articles have been empirically analysed using thematic analysis to identify trends in the existing literature. The data has been coded and analysed per decade (1982–1989, 1990–1999, 2000–2009, 2010–2019). The articles have been identified by searching major journals in the field of public relations and communications, as well as snowballing from identified articles.
Findings
The results show that the majority of academic articles have been produced by using lived experiences of women working in the public relations industry and thus reflect the professional situation of female public relations employees. The results show that the position of women has reached a full circle in four decades of research and returned to the discriminatory work environment. Finally, the results show that a liberal feminist perspective has an advantage in the literature since the majority of works have been produced in the United States; however, there is an increase in authors calling for the use of socialist and radical feminism.
Originality/value
The paper provides a comprehensive literature review of works published in the field. The paper takes an empirical approach to the analysis rather than the descriptive one, which helped in identifying major trends in the research and identified a research gap for future inquiries
Zika virus infections imported from Brazil to Portugal, 2015
Zika virus is an emerging arbovirus transmitted by Aedes sp. mosquitoes like the Dengue and Chikungunya viruses. Zika virus was until recently considered a mild pathogenic mosquito-borne flavivirus with very few reported benign human infections. In 2007, an epidemic in Micronesia initiated the turnover in the epidemiological history of Zika virus and more recently, the potential association with congenital microcephaly cases in Brazil 2015, still under investigation, led the World Health Organization (WHO) to declare a Public Health Emergency of International Concern on February 1, 2016.
Here, we present the clinical and laboratory aspects related to the first four imported human cases of Zika virus in Portugal from Brazil, and alert, regarding the high level of traveling between Portugal and Brazil, and the ongoing expansion of this virus in the Americas, for the threat for Zika virus introduction in Europe and the possible introduction to Madeira Island where Aedes aegypti is present.info:eu-repo/semantics/publishedVersio
QUANTIFILER®TRIO DNA method performance in a collection of ancient samples
Trabalho científico apresentado sob a forma de Poster no evento 9th ISABS Conference on Forensic Anthropologic Genetics and Mayo Clinicm Bol, Island of Brac, Croacia, 2015During the past few years significant progress has been made in solving technical challenges associated with STR profiling including the ability to analyze degraded DNA and low amounts of DNA. The result of these changes is that useful STR profiles can now be obtained from previously untypeable forensic DNA samples.
Analysis of DNA from ancient material represents an important role in molecular anthropology, although there are many limitations concerning low DNA quantity and/or degraded DNA, and/or PCR inhibitors. These factors can make it difficult to decide whether to continue with STR analysis, which STR panel to use and how much DNA to add to PCR reaction. With all these constraints, DNA quantification represents an important tool to decide which method will follow in order to improve workflow and have good results in less time-consuming.
The Quantifiler® Trio DNA method provides a quality index (QI) to detect the presence of degraded DNA along with PCR inhibitors.This guide allows the selection of the optimal short tandem repeat (STR) analysis chemistry (autosomal, or miniSTR) and streamlines the workflow while increasing downstream analysis success rates.
In order to compare DNA quality from different extraction methods, samples from 46 exhumed Middle Ages individuals were extracted with modified phenol-chloroform method and also PrepFiler Express BTA™ method.
DNA was quantified with Quantifiler® Trio DNA Quantification in an Applied Biosystems® 7500 Real-Time PCR System. Results were analyzed and allow us to point Quantifiler® Trio method as an important tool in pre-STR typing methods in ancient samplesN/
Topografía Infraclavicular De Los Fascículos Del Plexo Braquial En Diferentes Posiciones Del Miembro Superior
Brachial plexus neuropathies are common complaints among patients seen at orthopedic clinics. The causes range from traumatic to occupational factors and symptoms include paresthesia, paresis, and functional disability of the upper limb. Treatment can be surgical or conservative, but detailed knowledge of the brachial plexus is required in both cases to avoid iatrogenic injuries and to facilitate anesthetic block, preventing possible vascular punctures. Therefore, the objective of this study was to evaluate the topography of the infraclavicular brachial plexus fascicles in different upper limb positions adopted during some clinical procedures. A formalin-preserved, adult, male cadaver was used. The infraclavicular and axillary regions were dissected and the distance of the brachial plexus fascicles from adjacent bone structures was measured. No anatomical variation in the formation of the brachial plexus was observed. The metric relationships between the brachial plexus and adjacent bone prominences differed depending on the degree of shoulder abduction. Detailed knowledge of the infraclavicular topography of neurovascular structures helps with the diagnosis and especially with the choice of conservative or surgical treatment of brachial plexus neuropathies. © 2016, Universidad de la Frontera.

The ZEPLIN II dark matter detector: data acquisition system and data reduction
ZEPLIN-II is a two-phase (liquid/gas) xenon dark matter detector searching
for WIMP-nucleon interactions. In this paper we describe the data acquisition
system used to record the data from ZEPLIN-II and the reduction procedures
which parameterise the data for subsequent analysis.Comment: 11 pages, 10 figure

Limits on spin-dependent WIMP-nucleon cross-sections from the first ZEPLIN-II data
The first underground data run of the ZEPLIN-II experiment has set a limit on
the nuclear recoil rate in the two-phase xenon detector for direct dark matter
searches. In this paper the results from this run are converted into the limits
on spin-dependent WIMP-proton and WIMP-neutron cross-sections. The minimum of
the curve for WIMP-neutron cross-section corresponds to 0.07 pb at a WIMP mass
of around 65 GeV.Comment: 12 pages, 2 figures, to be published in Physics Letters
