Peculiarities of preparation of a vocational teacher for use of application software taking into account the requirements of the federal state education standard
The significance of the issue under study is due to the fact that nowadays there is a necessity of rethinking of conception of training future vocational teachers to use application software taking into account a competency-based approach. The article is aimed at studying the contradictions underscored while analyzing the conditions of the process of preparation of future vocational teachers for using application software within the educational process and also the ways of their solving realized with the help of the competency-based approach. The competency-based approach allows forming a system of requirements for the practical part of the research based on technology of project education. In the given research work the authors' viewing of principles of formation of conditions of preparation of the vocational teachers for using the application software within the education process is presented. The analysis of groups of conditions is made with regard to the discipline "Information Technologies in Education." With the use of traditional vision ("to know, to be able, to have") and vision from the point of view of Dublin descriptors. The contents of the article could be of interest for teachers who are engaged into training the Bachelors of Vocational Education (branch-wise) and also retraining in the sphere of use of the application software in the education process. © Authors
'I don't want anyone to know': Experiences of obtaining access to HIV testing by Eastern European, non-European Union sex workers in Amsterdam, the Netherlands.
Historically, the Netherlands has hosted a large number
of migrant sex workers. Since sex work is considered a legal
profession it might serve as an example of better access to
health services, including HIV testing, at least for those
working within the legal framework. However, migrant sex
workers, especially non-European Union (EU) nationals, might not
be eligible to register for official employment and thus face
obstacles in obtaining access to health services, becoming
essentially invisible. This study examined context-specific
vulnerabilities of migrant female sex workers (FSWs) from
Belarus, Moldova, Russia and Ukraine, whether and how they have
access to HIV testing compared to other EE, non-EU migrant FSWs
in Amsterdam in the Netherlands. We conducted a
multi-stakeholder perspective study from November 2015 to
September 2017 in Amsterdam. The study comprised 1)
semi-structured interviews with key stakeholders (N = 19); 2)
in-depth interviews with Eastern European, non-EU migrant FSWs
(N = 5) and field observations of the escort agency working with
them; and 3) in-depth interviews with key stakeholders (N = 12).
We found six key barriers to HIV testing: 1) migration and
sex-work policies; 2) stigma, including self-stigmatization; 3)
lack of trust in healthcare providers or social workers; 4) low
levels of Dutch or English languages; 5) negative experience in
accessing healthcare services in the home country; and 6) low
perceived risk and HIV-related knowledge. Having a family and
children, social support and working at the licensed sex-work
venues might facilitate HIV testing. However, Internet-based sex
workers remain invisible in the sex-work industry. Our findings
indicate the importance of addressing women's diverse
experiences, shaped by intrapersonal, interpersonal, community,
network and policy-level factors, with stigma being at the core.
We call for the scaling up of outreach interventions focusing on
FSWs and, in particular, migrant FSWs working onlin
'Virus Carriers' and HIV testing: navigating Ukraine's HIV policies and programming for female sex workers
Background: There are an estimated 80,100 female sex workers (FSWs) in Ukraine, of whom 7% are living with HIV.
Early HIV diagnosis continues to be a public health priority in Ukraine as only approximately 54% of people living
with HIV are diagnosed nationwide. This study aims to analyse the content, context and discourse of HIV testing
policies among female sex workers in Ukraine and how these policies are understood and implemented in practice.
Methods: To analyse past and current national policies, we searched the database of the Ukrainian Parliament and
the Ministry of Health for relevant policy documents (e.g. legislation and orders). To analyse the day-to-day practice
of those involved in the implementation of these HIV programmes, we conducted face-to-face semi-structured
interviews with key stakeholders. All data were coded using deductive thematic analysis initially guided by the
Policy Triangle, a framework which addresses policy content, the process of policy-making, the health policy
context, actors involved in policy formulation and implementation.
Results: HIV testing policies are formed and implemented in the post-Soviet context through a vertical system of
AIDS clinics, resulting in the separation of key affected populations from the rest of the health system. Successive
testing policies have been strongly influenced by international donors and non-governmental organisations.
Furthermore, a lack of government funding for HIV prevention created a gap that international donors and local
non-governmental organisations covered to ensure the implementation of testing policies. Their role, however, had
limited influence on the Ukrainian government to increase funding for prevention, including testing of FSWs. Since
the early 1990s, when stigmatising and discriminatory forced/mandatory HIV testing was applied, these approaches
were slowly replaced with voluntary testing, self-testing and assisted HIV testing, yet stigma was found to be a
barrier among FSWs to access testing.
Conclusion: Poor governance and the fragmentation of the health system, ongoing health sector reforms, shrinking
international funding, and persisting stigma towards people living with HIV and sex workers might impede the
continuity and sustainability of HIV testing programmes. Local civil society may now have the opportunity to contribute
to the development and further implementation of HIV testing policies in Ukraine
Scheme Independence and the Exact Renormalization Group
We compute critical exponents in a symmetric scalar field theory in
three dimensions, using Wilson's exact renormalization group equations expanded
in powers of derivatives. A nontrivial relation between these exponents is
confirmed explicitly at the first two orders in the derivative expansion. At
leading order all our results are cutoff independent, while at next-to-leading
order they are not, and the determination of critical exponents becomes
ambiguous. We discuss the possible ways in which this scheme ambiguity might be
resolved.Comment: 15 pages, TeX with harvmac, 2 figures in compressed postscript;

Depot Medroxyprogesterone Acetate Use and Blood Lead Levels in a Cohort of Young Women
BACKGROUND: Injectable contraceptive use is common, with 74 million users worldwide. Use of the injectable contraceptive depot medroxyprogesterone acetate (DMPA) is associated with bone mineral density loss. We hypothesize that increased bone resorption with DMPA use allows for mobilization of the toxic metal lead stored in bone to blood, presenting users with increased systemic exposure to lead.
OBJECTIVE: The objective of our study was to investigate the association between current DMPA use and blood lead concentrations.
METHODS: We conducted a cross-sectional analysis using enrollment data from the Study of Environment, Lifestyle & Fibroids (SELF), a cohort of 1,693 African-American women who were 23-35 years of age. Data on DMPA use were collected by computer-assisted telephone interview. Blood lead concentrations were measured in whole blood samples among 1,548 participants (91% of cohort). We estimated the adjusted percent difference in blood lead concentrations and 95% confidence intervals (CI) between current DMPA users and nonusers using multivariable linear regression.
RESULTS: Geometric mean blood lead concentration was 0.69 μg/dL (95% CI: 0.67, 0.71). After adjustment, current DMPA users (7% of cohort) had blood lead concentrations that were 18% higher than those of nonusers (95% CI: 8%, 29%). Similar associations were observed with additional analyses to assess for potential bias from smoking, DMPA-induced amenorrhea, use of estrogen-containing contraceptives, having given birth in the prior year, and history of medical conditions or current medication use associated with bone loss./
DISCUSSION: Our results indicate that current DMPA use is associated with increased blood lead concentrations. Further research, particularly in populations highly exposed to lead, is warranted to consider tradeoffs between the adverse effects of lead on human health and the importance of DMPA as a contraceptive option to prevent unintended pregnancy. https://doi.org/10.1289/EHP7017
On the mutual effect of ion temperature gradient instabilities and impurity peaking in the reversed field pinch
The presence of impurities is considered in gyrokinetic calculations of ion
temperature gradient (ITG) instabilities and turbulence in the reversed field
pinch device RFX-mod. This device usually exhibits hollow Carbon/Oxygen
profiles, peaked in the outer core region. We describe the role of the
impurities in ITG mode destabilization, and analyze whether ITG turbulence is
compatible with their experimental gradients.Comment: 19 pages, 9 figures, accepted for publication in Plasma Phys.
