Insight into an Acquired Accent of Maritime English Learners  [PDF]
Olena Tyron
Psychology (PSYCH) , 2018, DOI: 10.4236/psych.2018.95055
Abstract: The target audience of this article is Maritime English teachers. We have been researching students’ pronunciation before and after a shipboard training in multinational crews. We described the phenomena: The students after a long (approximately 6 months’ shipboard training at sea) returned in the English lecture room with a new acquired accent. From the planed interviews with the surveyed we got information about the national composition of the multinational crews. Then we analyzed information about the peculiar properties of these nations’ pronunciation. We also studied the features that form an accent in English of the Ukrainians. We claim that the theory of converge (make their speech similar to the style of their addressee) and diverge (make their speech different to the style of their addressee) can explain the accent of the students after the shipboard training in a multinational crew. But we assert that inaccuracies in the pronunciation of certain words can distort the accuracy of the utterance and will lead to violations of professional activity. In this connection we consider that any accent in seafarers’ speech has a negative effect on the safety of navigation and seafarers should tend to Standard English pronunciation. Nevertheless, an acquired accent as a result of convergent behavior, have a positive effect in the social-psychological aspect. The research proves that the teachers of Maritime English should: consider the accent as manifestation of ability to use convergence; teach and accept only Standard English especially in the context of safety of navigation; understand the psychological origins of the desire to demonstrate the acquired accent as a manifestation of divergence and skillfully shape the motivation of students to have a standard pronunciation.

Prediction of development of the multi-phase alternative for the course inherent to acute disseminated encephalomyelitis (ADEM) is of great clinical importance, as it enables timely determination of the treatment tactics as well as volume of respective therapeutic interventions. This work is aimed at ascertaining the prognostic factors that determine the risk of development of the multi-phase course in disseminated encephalomyelitis. We have examined 101 patients with the diagnosis ADEM, namely: 28 men and 73 women in the age from 17 up to 53 years (average value 31.7 ± 1.01 years). To ascertain the prognostic meaning of clinic-paraclinic indices corresponding to patients with ADEM, we estimated the cumulative part of absence of relapses in the group of patients by using the Kaplan-Meyer method with estimating the Fisher criterion and using the most important clinic-paraclinic data. Development of the multiphase course in ADEM is reliably related to the following prognostic signs: changes in the neurologic status of patients with ADEM, degree of disability in accord with the EDSS scale as well as sizes of demyelination focuses determined using MRT. Criteria for congenial prediction in disease development with delayed appearance of ADEM relapses in the form of the multi-phase course are as follows: domination of motor impairments over coordinative impairments in neurological status, slight degree (in EDSS scale) of disability and small sizes (up to 4 mm) of demyelination focuses (MRT data). Our analysis of the main clinic-paraclinic indices obtained using the Kaplan-Meyer method indicates reliability of results and enables us to find a number of important prognostic criteria for appearance of the multiphase course in ADEM.

Advances in Bioscience and Biotechnology (ABB) , 2015, DOI: 10.4236/abb.2015.68058
Abstract: The comparative analysis of the monolignols localization in epidermis, photosynthesizing parenchyma and vessels walls of Myriophyllum spicatum, Potamogeton pectinatus and P. perfoliatus submerged leaves carried out on the basis of cytochemical method and laser confocal microscopy. The images of quantitative distribution of syringyl and guaiacyl in the cell walls were obtained at cellular level depending on the type of leaf tissues and plant species. The increase of relative content of monolignols was established in walls of vessels and in the corners of parenchyma cells. Cytochemical analysis indicates that ratio of syringyl/guaiacyl in leaf tissues changes depending on species. The role of of syringyl and guaiacyl monolignols in the cellular mechanisms of adaptation to nature flooding is discussed.

Advances in Microbiology (AiM) , 2014, DOI: 10.4236/aim.2014.412089
Abstract: The composition of tightly bound exopolymeric substances (EPS) obtained from biofilm and plan- ktonic cell subpopulations of Stenotrophomonas maltophilia 5426 UKM was analyzed to study an impact of mild steel presence in the cultivation medium. The overall protein production was found to increase in the presence of a steel coupon. Some amino acids such as lysine, valine, iso-leucine, tyrosine and phenylalanine were found to be secreted in higher amounts in the presence of mild steel, while its absence leads to an increase of arginine, asparagine, serine, glutamine, proline, glycine, cysteine, leucine, methionine production levels. Biofilm cells EPS contained more arginine, glycine, cysteine, valine, methionine and leucine, comparing to EPS of planktonic cells. The chang- es of tightly bound EPS aggregation around the cells induced in the presence of steel coupons were revealed by transmission electron microscopy. The results suggested the transition of S. maltophilia 5426 UKM cells from planktonic to biofilm lifestyle to be a complex process involving more than a single step.
Trends in Markets for Forest-Based Products and Consequences for Selected Countries  [PDF]
Olena Maksymets, Lars L?nnstedt
Open Journal of Forestry (OJF) , 2015, DOI: 10.4236/ojf.2015.57062
Abstract: The forest sectors in many regions and countries are facing a need to change their structure, due to the development of new markets, emergence of new competitors, and shifts in production and consumption patterns for forest products. This article focuses on recent changes in the trade in these products, on imports and exports of four countries (USA, Sweden, Ukraine and, to a lesser extent, China) during the period from 1995 to 2011. For this purpose we use explanatory data analysis, time series analysis, benchmarking, meta-synthesis and content analysis of scientific and business publications concerning national and global trends in forest product industries. Data sources are various organizations’ databases of international trade in forest-based products in both monetary and physical terms (cubic meters and tons). The results show that the US and Swedish forest sectors are adversely affected by downturns in both their domestic and foreign markets during the study period, while the Ukrainian sector maintains exports of low value-added products at roughly constant levels (except that particle-board exports increase). China maintains production quantities of low value-added forest-based products, but also substantially increases exports of high-value added products. The results may facilitate efforts to forecast future trends and provide useful information and methodological approaches for future studies of interest to industry representatives, policy-makers and researchers.

Baltic Journal of Health and Physical Activity , 2009, DOI: 10.2478/v10131-009-0005-x
Abstract: Background: The features of functional capacities of elite basketball players related to game functions (players of various lines) have been analyzed on the basis of evaluation of the physiological reactivity characteristics It has been assumed that some specific characteristics are related to efficient competitive activity and are manifestations of endurance: power of cardiorespiratory system (CRS), economy, mobility, stability and ability to realize the potential of the system for specific workload. Material/Methods: Twenty nine elite male basketball players were examined during the competitive period of training. For the analysis of CRS response to physical exercises the complex of the tests for estimating aerobic capacity and anaerobic possibilities of athletes were used. Results: The results showed that basketball players of various game functions have different levels of functional fitness and components of aerobic capacities Conclusion: A possibility to efficiently control the preparation of athletes and determine the most optimal character of their competitive activity has been considered on the basis of an account of functional capacities level and differences in its levels in athletes of different game functions.
Phraseologismen als Quelle der Wortbildung. Phraseological units as source of word-formation
Olena Lazarenko
Kalbotyra , 2008,
Abstract: Phraseological units are not only steady constructions, the transition of free word-combinations in semantically indivisible and syntactically entire word-combinations, but they also serve as a buil-ding material for new words.The article is devoted to the productivity of phraseological units in word-formation of the Ger-man language. The object of my research is 1200 lexemes motivated by phraseological units. The research material is extracted from lexical and phraseological dictionaries, the German belles-lettres and press. The purpose of this study is to analyse linguistic and extralinguistic factors causing the process of the dephraseological derivation, basic word-formation mechanisms and ways of enri-ching vocabulary on the basis of phraseological units.
Early initiation of alcohol consumption by adolescents in reconstructed families may be explained by parenting style
Iakunchykova, Olena
Tobacco Control and Public Health in Eastern Europe , 2011,
Abstract: BACKGROUND. Literature about risk factors of alcohol use points at the association between alcohol use and parenting style. This study investigates the relationship between family structure of adolescents in Ukraine and their initiation of alcohol use with parenting style as a mediating variable.METHODS: Pooled data from the repeated cross-sectional nationally representative survey of classes in Ukrainian secondary schools with target group of all 15-16 year old students, held in 1999, 2003, and 2007, were used for this analysis. Complete data were available for 11019 participants. Main exposures were family structure (full, single parent and reconstructed) and perceptions of the relationships with mother and father, rule-setting, control, and support provided by parents. Outcome measure was age when students started consuming alcohol.RESULTS: In bivariate analysis, children in reconstructed families had higher risk for initiating alcohol use at age of 13 or younger (odds ratio 1.37, confidence interval 1,15-1,63) compared to full families. In reconstructed families, adolescents were more likely to be dissatisfied with their relationships with mother compared to intact family structure (8.7% vs. 4.7%) and dissatisfied with their relationships with father compared to intact family structure (19,8% vs. 9,1%). Parental support was lacking in higher proportion of reconstructed families, compared to intact family structure (20.7% vs. 15.1%). In the multivariate analysis, controlling for relationship with mother and father, support received from parents, and socio-demographic characteristics, the association between family structure and alcohol drinking initiation was attenuated.CONCLUSIONS: Children in reconstructed families have higher risk of early drinking initiation. This study also supports the hypothesis that dissatisfaction with relationships with parents and lack of support received from parents may mediate the association between family structure and early drinking initiation. Hence, reconstructed families may require additional attention of public health professionals in their prevention programs.
The determinants of quitting or reducing smoking due to the tobacco tax increase
Tigova, Olena
Tobacco Control and Public Health in Eastern Europe , 2011,
Abstract: BACKGROUND. Ukraine has adopted State targeted social program for reducing the harmful effects of tobacco on public health in Ukraine till 2012. One of the measures to be implemented is increasing excise tax on tobacco products; therefore, a highly important question is which groups of population are likely to benefit from tax increase through quitting or reducing smoking.METHODS. Data used for analysis were collected in a nationally representative survey of Ukrainian population conducted in 2010. An outcome measure was the anticipated keeping smoking versus quitting (reducing) smoking due to tobacco tax increase. Independent variables included socio-demographic characteristics, experience of quitting smoking, exposure to different tobacco control measures, exposure to tobacco advertizing. Binary logistic regression was used to measure associations.RESULTS. Respondents were more likely to expect to keep smoking after the tobacco tax increase if they were dependent on tobacco (odds ratio 2.57), not interested in quitting, not in favor of tobacco tax increase, and exposed to tobacco advertising on TV and cigarette promotions. Respondents were more likely to expect to reduce or quit smoking if they had higher wealth status (OR=0.55), were aware of tobacco health hazard (OR=0.09), had earlier attempts of quitting smoking, were not exposed to secondhand smoke, observed tobacco-related information on television (OR=0.7) and in newspapers (OR=0.45), and observed advertizing of tobacco on radio (OR=0.33) and in public transport (OR=0.25).CONCLUSIONS. Several aspects are important while implementing taxation policy. It is more likely to result in quitting or reducing smoking among those who are less dependent, have tried quitting smoking earlier, and have higher wealth level. Concurrent smoke-free policies and awareness campaigns may potentiate the effect of taxation policies and are recommended to be developed further.
