Authors: Śmiech Anna , Łopuszyński Wojciech , Ślaska Brygida , Bulak Kamila , Jasik Agnieszka 
Published: February 2019

Abstract

Introduction: Breed predisposition to cutaneous mast cell tumours (MCT) in a population of dogs in Poland affected by various skin tumours was assessed, and the distribution of MCT characteristics such as histological grading, sex, age, and location, in predisposed breeds was evaluated.

Material and Methods: The retrospective epidemiological study included 550 dogs affected by cutaneous MCTs with a reference group of 2,557 dogs diagnosed with other skin tumours.

Results: A univariable logistic regression analysis was performed to determine the odds ratios (ORs) with 95% confidence intervals. The risk of high-grade MCTs was the highest for Shar-Peis (OR: 26.394) and American Staffordshire Terriers (OR: 2.897). Boxers (OR: 6.619), Labrador Retrievers (OR: 2.630), French Bulldogs (OR: 2.050), Golden Retrievers (OR: 1.949), and American Staffordshire Terriers (OR: 2.592) were mainly affected by low-grade MCTs. The high risk of MCT was calculated to be at the age of 4–6 years for Labrador Retrievers (OR: 2.686) and 7–10 years for Boxers (OR: 2.956) and French Bulldogs (OR: 9.429). MCTs were significantly more often located on the trunk in French Bulldogs (OR: 4.680), American Staffordshire Terriers (OR: 2.520), and Labrador Retrievers (OR: 1.948). There was no statistically significant correlation between gender and the occurrence of MCTs in the breeds.

Conclusions: The breed-predicated differences in the clinical course of MCTs suggest a genetic background for the tumours.

Abstract

Introduction: Peroxiredoxin 6 (Prdx6) is a bifunctional protein with glutathione peroxidase activity and phospholipase A2 activity. Previous studies have shown a significant positive correlation between the intracellular survival ability of Brucella and Prdx6. Here, the Prdx6 enzyme with a single activity was constructed to facilitate study of the relationship between the single function of Prdx6 and Brucella infection.

Material and Methods: The target open reading frame (ORF) DNAs of Prdx6 with a single active centre were prepared using gene splicing by overlap extension PCR (SOE-PCR), and the recombinant eukaryotic expression plasmids inserted by Prdx6 with the single activity centre were constructed and transfected into murine Raw264.7 macrophages. The glutathione peroxidase activity and phospholipase A2 activity of the constructed Prdx6 were examined.

Results: The core centres (Ser32 and Cys47) of Prdx6 were successfully mutated by changing the 94th nucleotide from T to G and the 140th nucleotide from G to C in the two enzyme activity cores, respectively. The constructed recombinant plasmids of Prdx6 with the single active centre were transfected into murine macrophages showing the expected single functional enzyme activity, which MJ33 or mercaptosuccinate inhibitors were able to inhibit.

Conclusion: The constructed mutants of Prdx6 with the single activity cores will be a benefit to further study of the biological function of Prdx6 with different enzyme activity.

Published: February 2019

Abstract
The study investigated the challenges of marketing Abakaliki rice with interest in establishing the profitability and socio-economic characteristics of the marketer of the product. Mixed-method research approach consisting of the application of questionnaires and interview was used. It was conducted in three major markets located at Onu Ebonyi, Abakpa and Kpirikpiri in Ebonyi state, Nigeria. The population of the study was 120 marketers randomly selected using simple random sampling technique and proportional to the size of the market. Data was analysed using descriptive statistics. The results shows that women dominate the trade as 62% of Abakaliki rice marketers are women. Challenges of institutional, transportation facilities capital and credit facility constrained the growth of the business. Cost benefit analysis also shows that marketing of Abakaliki rice is profitable as N192, 740 only was the net profit at the end of the trading period. The study concludes by recommending formation of cooperative societies to enhance accessibility of start-up capital while governments at various levels should develop marketing policies that increase the marketing network of Abakaliki rice.

Published: February 2019

Abstract
Although the immigrant population in Spain has decreased due to the economic crisis of the past five years, few studies have analysed this group. The objective of this research has been to profile the immigrant who decides to start a business in Spain. In order to learn about the probability of immigrant workers being entrepreneurs as a function of their socio-demographic characteristics, data from the Spanish National Institute of Statistics from 2005 to 2016 have been analysed and fieldwork carried out during August and September 2016 on immigrants who are self-employed. The results show a lower rate of entrepreneurship in the immigrant population vis-a-vis the native population and the fact that creating their own business begins at an earlier age for immigrants when compared to the national average.

Published: February 2019

Abstract
This research tried to identify similarities and differences in motives between male urban entrepreneurs from Mexico and Morocco. The Mexican sample of 192 respondents was drawn from Chambers of Commerce listings in Guadalajara and Monterrey. The Moroccan sample of 222 respondents came from the Fès-Meknès region. In both countries a majority of entrepreneurs went into business by necessity and pursued monetary goals in order to secure their financial future for their families and for themselves. Larger cohorts of younger entrepreneurs were present in Mexico, where female spouses tended to be more often involved in their husband’s business and contributing more to family income, as compared to Morocco. In Mexico, a larger proportion of entrepreneurs were also expressing a very strong interest for intrinsic goals involving self-actualization, meeting challenges, while Moroccan respondents were more in search for autonomy and independence besides pursuing extrinsic or financial goals. Results generally confirm results obtained elsewhere in Africa and Latin America.

Authors: Hou Jin , Jiang Qiwang 
Published: February 2019

Abstract
Nanosized NaA zeolite was successfully synthesized by hydrothermal method using tetraethyl orthosilicate (TEOS) and aluminum isopropoxide (AIP) as the main raw materials. The surface modification of NaA zeolite was carried out by silane coupling agent 3-aminopropyltriethoxysilane (KH-550). The effects of silane coupling agent dosage, reaction temperature, reaction time, hydrolysis time and pH value on grafting rate of NaA zeolite were investigated in detail. The zeolites were characterized by XRD, SEM-EDS, FT-IR and TG-DTA. The results showed that the surface of NaA zeolite was modified successfully by KH-550. The optimal modification conditions obtained were as follows: the dosage of coupling agent in 95 % ethanol – 1.6 %, reaction temperature − 70 °C, reaction time – 2 h, hydrolysis time – 20 min, and pH value – 3.5. Under these conditions, the grafting rate of modified NaA zeolite was 3.95 %.
Data Visualization in Scandinavian Newsrooms: Emerging Trends in Journalistic Visualization Practices
Authors: Engebretsen Martin , Kennedy Helen , Weber Wibke 
Published: February 2019

Abstract
The visualization of numeric data is becoming an important element in journalism. In this article, we present an interview study investigating data visualization practices in Scandinavian newsrooms. Editorial leaders, data journalists, developers and graphic designers in 10 major news organizations in Norway, Sweden and Denmark provide information for the study on a range of issues concerning visualization practices and experiences. The emergence of multi-skilled specialist groups as well as innovation in technology and the ‘mobile first mantra’ are identified as important factors in the fast-developing practices of journalistic data visualization. Elements of tension and negotiation are revealed for issues concerning the role and effect of complex exploratory data visualizations and concerning the role of ordinary journalists in the production of charts and graphs.
Please Like, Comment and Share our Campaign!: How Social Media Managers for Danish Political Parties Perceive User-Generated Content
Authors: Farkas Johan , Schwartz Sander Andreas 
Published: February 2019

Abstract
Based on 18 qualitative interviews, this article explores how the social media managers for the nine parties in the Danish parliament articulate the role of social media during the 2015 national elections. The article finds that the interviewees emphasise Facebook as an important means for one-way political communication and the monitoring of public opinion. The majority of the interviewees articulate a sense of responsibility for facilitating public debate on Facebook through the moderation of user-generated content and/or interactions with users. Yet the social media managers do not systematically analyse political input from social media users, nor do they see Facebook and Twitter as viable means of citizen influence on political decision-making. This is explained by a perceived lack of voter representativeness among Facebook users, fear of appearing politically imprudent and scepticism towards social media’s participatory potential.
Local Newspapers, Facebook and Local Civic Engagement: A Study of Media Use in Two Norwegian Communities
Authors: Lie Malene Paulsen 
Published: February 2019

Abstract
The European decline in newspaper circulation has fuelled debates on the consequences for civic engagement and democratic participation. Based on a qualitative interview study with 29 inhabitants of two Norwegian communities, this article examines the importance of the local press and of Facebook in the civic actions of ordinary citizens. Overall, the study suggests that both media are important and enable citizens’ involvement in collective problem-solving. However, their importance lies on different levels, as the two media play complementary roles: Whilst Facebook’s networking possibilities enable new forms of online volunteering and mobilisation, the local press constitutes a shared public sphere in which interviewees can gather information and create awareness of local happenings, politics and volunteering.
Jewel in the Crown: The Nobel Banquet Broadcast as Co-Construction
Authors: Ganetz Hillevi 
Published: February 2019

Abstract
This study explores the aims of the Nobel Banquet broadcast, produced by the Swedish public service company SVT and the Nobel Foundation. The study suggests that the programme can be viewed as a co-construction of science and media, and that the Nobel Foundation has three primary purposes: 1) to teach the audience about science; 2) to honour the laureates; and 3) to maintain and increase the status of the Nobel prize. SVT, for their part, has two main purposes: 1) to teach their audience about science, and 2) to entertain. The aims of the Nobel Foundation and SVT may seem disparate, but they are interrelated. At the same time, the subtleties between the entities create a tension that develops through mutual negotiations. The study ends with a discussion of two unexpected findings: 1) the shared, yet essentially differently-grounded aims of both parties to inform about science, and 2) the fact that their scientific content has increased in both absolute and relative terms over the years, a finding that questions notions of a continuous mediatisation of social institutions.
Educating Land Forces’ Leaders to Think from JIIM Perspective
Authors: Tudorache Paul , Ispas Lucian 
Published: February 2019

Abstract
Nowadays, the military forces’ operational environment is shaped by dynamic changes that give its most representative characteristics such as volatility, uncertainty, complexity and ambiguity (VUCA). Based on this and taking into consideration the tendency of NATO to use more prominently its multinational military structures, we are obligated to adapt our way of teaching and training if we want to be effective in the process of educating the next leaders for future military environments. In other words, during the classes, also in the field, we should try to educate and train our cadets, at least, to think from a joint, interagency, intergovernmental and multinational (JIIM) perspective when conducting military actions, even at a small tactical level, such as the platoon.
Could The Insolvency Risk for Companies Traded on Bucharest Stock Exchange have been Identified? A Case Study Using the Altman Model
Authors: Vasiu Diana Elena 
Published: February 2019

Abstract
Insolvency represents the state of the debtor’s patrimony characterized by insufficient funds available for the payment of certain, liquid and due debts. It may occur even in case of strong companies, for example, in case of listed companies, generating loses for investors. In economic theory, a series of insolvency risk prediction models were developed, based on the method of scores, the most known and used being the Altman model. At the present moment, five companies, traded at Bucharest Stock Exchange are insolvent. The aim of this paper is to establish if the Altman model can successfully be used for Romanian traded companies, to determine the risk of insolvency.

Abstract
In recent years, a significant number of epidemiological variations have been observed for fungal infections. In immunocompromised patients, Candida albicans is crucially involved in invasive infections, mostly originating in respiratory tract colonization. The global rise in candidiasis has led researchers to investigate possible correlations between fungal strains virulence profiles and their pathogenic potential, among the most investigated genes being those involved in adherence and biofilm development. In this study, we established the adherence gene profiles of C. albicans strains isolated from respiratory tract secretions in patients hospitalized for cardiovascular diseases and correlated them with the ability of the respective strains to colonize the epithelial cells and form biofilms on the inert substratum. The strains isolated from the lower respiratory tract exhibited the highest adherence capacity and were intensive biofilm producers. The SAP9, ALS3, ALS5, and ALS6 genes were the most frequently detected. There was a significant association between the presence of ALS 3 gene and the cellular substrate colonizing potential of the harboring strains. We also found that the strains expressing SAP9 were more virulent in the phenotypic assays. Detecting the presence of adherence genes from different clinical isolates is a cost-effective tool that would allow researchers to predict the virulence of a certain strain and estimate its potential to adhere to host cells and develop biofilms.

Published: February 2019

Abstract

Purpose: Ovarian torsion, being a gynecological emergency, requires to be rapidly diagnosed and treated with minimal consequences on ovarian function after the removal of torsion. As ischemia modified albumin (IMA) is considered a good biomarker in diverse ischemic diseases, the aim of our study was to determine the effect of different ovarian torsion/detorsion models on serum and ovarian homogenates levels of IMA in an experimental study.

Methods: IMA was measured in the serum and ovarian homogenates of 7 groups of female rats (10 animals in each group): 1 - control (no intervention); 2 - sham (only laparotomy); 3 - ischemia group: 3 hours ovarian torsion (OT); 4 - 3 hours OT (ischemia), 1 hour simple reperfusion; 5 - 3 hours ischemia, 1 hour controlled reperfusion that was assured during the first two minutes by opening and closing the clips on the ovarian pedicles in 10 seconds intervals, followed by simple reperfusion; 6 - 3 hours ischemia, 24 hours simple reperfusion; 7 - 3 hours OT, 24 hours controlled reperfusion. The results were analyzed by Welch’s ANOVA and Spearman correlation.

Results: Ischemia increases the IMA in both serum and ovarian homogenates compared to control and sham groups. The controlled reperfusion groups had a statistically significant lower IMA in serum compared to simple reperfusion groups. IMA was found to be higher in the ovarian homogenates of simple reperfusion compared to controlled reperfusion groups.

Conclusion: Our results suggest that controlled reperfusion prevent the processes that increase the IMA in ovarian torsion.

The result obtained are: 1) the enhancement of students’ mathematical connection ability who were taught under LC 5E is better than those who were taught under conventional learning; 2) there is different enhancement mathematical connection ability who were taught under LC 5E learning based on MPA (upper, middle, lower levels); 3) the enhancement of students’ mathematical comunication ability who were taught under LC 5E is better than those who were taught under conventional learning; 4) there is different enhancement mathematical comunication ability who were taught under LC 5E learning based on MPA (upper, middle, lower levels) Keywords: Learning cycle 5E, mathematical connection ability and mathematical communication ability.
Translating a Portuguese poem in LIBRAS. Linguistic considerations and form-focused tasks.
Authors: Mertzani Maria 
Published: February 2019

Abstract
The teacher of deaf children in primary education is called to apply sign bilingualism in his/her teaching, and hence to use sign language - such as LIBRAS - as the first language during in-class time, and as a school subject. This again means that all other subjects - among them Portuguese - need to be taught in SL. In fact, Portuguese is taught as the second language of deaf children. In such educational setting, the teacher needs to develop learning materials for LIBRAS. Current research lacks recording such practices, although, unofficially, it is common knowledge that teachers translate existing school materials that have been developed for Portuguese and for hearing pupils in primary education. In this paper, a LIBRAS translation is presented of the poem “As abelhas” by Vinícius de Moraes, with the scope to demonstrate its linguistic use for the teaching of LIBRAS as a first language. Apart from its target vocabulary items, form-focused tasks are demonstrated, indicating their implementation for the development of deaf children’s receptive and productive skills. In doing so, the poem is presented following the A-level descriptors (A1, A2) of the Common European Framework of Reference for Sign Languages.
A mobilização da competência interpretativa na atuação de conferências:
Authors: Nogueira Tiago Coimbra 
Published: February 2019

O presente artigo abordará uma reflexão sobre o modelo de competência tradutória do grupo PACTE (2003), relacionando as subcompetências com a prática de interpretação. Mais especificamente, com a interpretação de conferências na atuação de intérpretes de Libras-Português, atuando em equipe e em cabine. Busca-se problematizar e apresentar uma reflexão sobre a aplicabilidade das subcompetências do referido modelo à atividade de interpretação na mobilização de uma competência interpretativa. No campo dos Estudos da Tradução, há uma diferenciação que define processos de tradução e interpretação. A prática da interpretação está ligada ao ato de o profissional intérprete estar envolvido no diálogo, suas palavras são dirigidas a um destinatário direto e busca-se provocar uma reação em uma velocidade muito maior do que a da tradução. A partir de Camargo (2014), olhamos para o processo de interpretação realizada pela equipe de intérpretes do Congresso Nacional de Pesquisas em Tradução e Interpretação de Libras e Língua Portuguesa, formada por seis membros, que foram observados e entrevistados. Propomos essa reflexão sobre onde e em quais momentos as subcompetências são mobilizadas pela equipe de intérpretes. De modo geral, todas as cinco subcompetências descritas pelo PACTE são ativadas durante a prática de interpretação, porém, há refinamentos e momentos distintos. A partir dos resultados, espera-se contribuir com reflexões a respeito das competências necessárias para a atividade de interpretação.
