Le travail en élevage et ses mutations
Authors: SERVIÈRE Gérard , CHAUVAT Sophie , HOSTIOU Nathalie , COURNUT Sylvie 
Published: May 2019

Pour les éleveurs, la diversité des tâches, la liberté d'agir à sa guise, la proximité avec la nature et les animaux expliquent l'attrait, souvent passionné, pour une profession en constante mutation suite aux évolutions techniques et sociologiques. Les gains d'efficience et de productivité sont rognés par l'augmentation de la taille des structures et la charge de travail reste toujours importante. Aujourd'hui les éleveurs cherchent un meilleur équilibre vie privée/vie professionnelle, à préserver leur santé et une reconnaissance de leur rôle sociétal, ce qui implique des conditions de travail correctes et plus de sérénité au quotidien. L'automatisation et la robotisation demandent d'acquérir une maîtrise technologique mais apportent de la souplesse et permettent des gains de temps. Le développement du salariat et de la féminisation des chefs d'exploitation, modifient le rapport au métier et pourraient contribuer davantage au renouvellement des générations. Les préoccupations, environnementales et vis-à-vis du bien-être animal, suscitent des infléchissements, notamment agro-écologiques qui nécessitent de nouveaux apprentissages et des transitions toujours complexes. Les remises en cause, parfois frontales, de l'élevage côtoient des initiatives démontrant son utilité sociale comme pourvoyeur d’emplois, d’identité locale et de produits sains. La diversité dans les territoires des modèles d’élevage, les complémentarités entre eux et avec d'autres activités, agricoles ou non, ainsi que le renouvellement des outils de conseil sont autant de perspectives pour susciter le désir de « devenir éleveur ». Cet article présente, à la lumière des mutations sociales, sociétales et économiques, les questions en débat autour du travail et du métier des éleveurs.

Authors: Arfianti Arfianti 
Published: May 2019

The prevalence of childhood overnutrition is increasing in many parts of the world including Indonesia. National basic health research (RISKESDAS) 2010 showed that over-nutrition in urban children (10.4%) was greater than in rural areas (8.1%). The purpose of this study was to analyse risk factors for overnutrition on elementary students in urban and rural areas in Pekanbaru. This was an observasional analytical study with cross-sectional design. This study involved 137 urban and 113 rural students from six elementary schools in Pekanbaru recruited by quota sampling technique. This study was conducted between April-May 2018. The results showed that the proportions of overweight and obesity in urban Pekanbaru were 16.1% and 16.8% respectively, while in rural areas were 12.4% and 9.7%, respectively. Furthermore, outdoor activity and snacking habit were significant contributors of childhood overnutrition in urban area whereas frequency of main meal was associated with childhood overnutrition in rural area. In conclusion, there was no difference in the incidence of overnutrition among elementary students in urban and rural areas in Pekanbaru. This study indicated that obesity risk factors may be different between urban and rural areas in Pekanbaru.

Published: May 2019

Indecisiveness and negative thinking regarding career pathways can hinder university students’ career planning, motivation, and mental health. Students intending to enter the workforce after graduation therefore need to develop skills related to career adaptability (i.e. career planning, decision-making, problem solving/confidence and exploration), particularly since career planning and construction is linked to gaining employment. This study aimed to test the effectiveness of an online career planning module on students’ career adaptability. The career-focussed online module, based on the constructs of Savickas’ (2005) theory of career construction, and tailored to students’ skills and interests, was developed and embedded into the University curriculum of a second-year exercise and public health-related unit. In 2018, 80 students completed the online module, along with pre- and post-intervention questionnaires assessing career adaptability elements including career planning, decision making, problem solving/confidence, and exploration. Dependent t-tests were conducted to assess differences in these measures pre- and post-intervention. Post-intervention, significant increases in career-planning strategies used (t(69)=5.45, p<0.001), career planning concern (t(69)=3.73, p<0.001), decision making (i.e. career path identification) (t(70)=3.86, p<0.001), decision making confidence (t(65)=2.69, p<0.01), and problem solving/confidence (t(65) = 2.16, p=0.03) were observed. Further, 80% of participants identified jobs at post-intervention not previously identified pre-intervention (exploration) and 71% of participants perceived improvements in confidence regarding job ideas/making career choices. Findings from this research indicated that completing a brief online career education module, tailored to an individual’s skills and interests, improved all dimensions of the participating students’ career adaptability. Further research utilising longer-term follow-up and randomised controlled trial designs are required to confirm the reliability and transferability of the findings.
Beyond employability skills: Developing professional purpose
Authors: Bates Glen , Rixon Andrew , Carbone Angela , Pilgrim Chris 
Published: May 2019

Rapid transformation of the workplace and a highly competitive labour market has changed the nature of graduate employability. In addition to discipline related knowledge, students now need to be proactive and adaptable in identifying career opportunities. This paper presents a conceptual model that views employability as determined by an overarching professional purpose mindset. This mindset reflects a person’s commitment to developing a professional future aligned to personal values, professional aspirations and societal outlook. Four specific mindsets are encapsulated within professional purpose (curiosity, collaboration, action and growth) and relate to three domains of development (self and social awareness; navigating the world of work and networks). Two studies were conducted to explore the professional purpose model. Study one was a qualitative study in which 33 undergraduate students (19 female; 14 male) explored their career decision making. Focus group and interview data showed that each of the four positive mindsets operated in many students’ proactive career related behaviours. However, for other students, alternative mindsets negatively influenced their career related behaviour. In the second study, 42 academics (28 male; 14 female) identified unit learning outcomes in existing curricula related to the three domains of development. All domains were evident but outcomes for navigating the world of work received most emphasis. Implications of the findings for further development of the professional purpose model are discussed.

Authors: MITREA Laura , TRIF Monica , RUSU Alexandru , Vodnar Dan-Cristian 
Published: May 2019

Abstract
Background
Despite being a well-known human pathogen, Klebsiella pneumoniae plays a significant role in the biotechnology field, being considered as a microbial cell factory in terms of valuable chemicals biosynthesis. In fermentation processes, K. pneumoniae is mostly used to biosynthesize 1,3-propanediol (PDO), a very important intermediate compound utilized in the biodegradable bioplastics industry. This strain owns the ability to metabolize glycerol and to produce PDO under both aerobic and anaerobic circumstances, and under low oscillations of pH.
Results
In this work, we investigated the K. pneumoniae strain DSMZ 2026 in batch bioreactor cultivation. The bacterial strain was inoculated in 2 L culture broth containing 43.5 g·L- 1 main substrate and the pH was adjusted at 7 at the beginning of the process. After 12 h of batch cultivation, the pH values decreased to 4.77, and we obtained 51 g·L-1 wet biomass, 17 g·L-1 PDO, while the starting substrate reached 15 g·L- 1. The morphology of K. pneumoniae cells was analyzed on both solid and liquid media, by being identified large mucoid colonies on Columbia agar, and individual and grouped cells were observed by methyl blue staining.
Conclusion
From this study it can be concluded that K. pneumoniae can grow successfully in mineral broth under anaerobic environment and low decrease of pH, and can biosynthesize valuable chemicals like PDO.

Published: May 2019

Abstract
Background

Carbapenem-resistant hypervirulent Klebsiella pneumoniae strains have recently come into existence worldwide; however, researchers in northeast China are not aware of their clinical features and molecular characteristics.

Methods

Here, the molecular and virulent characteristics of 44 carbapenem-resistant K. pneumoniae (CRKP) isolates collected from January 2015 to December 2017 were studied. Multilocus sequence typing (MLST) and pulsed-field gel electrophoresis (PFGE) were carried out to define the clonal relatedness among the isolates. PCR and capsular serotyping of the virulence-associated genes, as well as biofilm formation and serum complement-mediated killing assays, were employed to determine the virulent potential. The genomic features and associated mobile genetic elements of JmsCRE57 were detected by whole genome sequencing.

Results

The only positive isolate was JmsCRE57, which belonged to the ST375 serotype K2 that expressed uge, mrkD, fimH, kpn, aerobactin and rmpA virulence-associated genes and showed strong biofilm formation and serum sensitivity. Sequencing results showed that the JmsCRE57 genome mainly consisted of a circular chromosome, three antibiotic resistance plasmids and a virulent plasmid. The antibiotic resistance plasmid expressing blaKPC-2, blaCTX-M-15, aph(3'')-Ib, aph(6)-Id, qnrB1, aac(3)-IIa, aac(6')-Ib-cr, blaOXA-1, blaTEM-1B, catB4, sul2, dfrA14 and blaSHV-99. The virulent plasmid belonged to the IncHI1B group, which is mainly composed of capsular polysaccharide genes and siderophore-associated genes. The remaining CRKP strains that expressed uge, fimH, mrkD and kpn virulence-associated genes were not successfully typed. We also identified an isolate that expressed the alls gene.

Conclusion

Our results provide new insights on the epidemiology of carbapenem-resistant K2 hypervirulent K. pneumoniae ST375 and CRKP ST76 strains in northeast China, which may help control their future outbreaks.
Isolation of bacteriophages from untreated sewage water against multi-drug resistant E.coli - An initiative to fight against drug resistance
Authors: Qamar Hina , Owais Mohd , Chauhan Dushyant Kumar , Rehman Sumbul 
Published: May 2019

Abstract
Background: Pathogenic Escherichia coli, common drinking water contaminant, cause a large number of morbidity and mortality worldwide. According to the WHO estimates approximately 63,000 annual deaths are due to E. coli infections. Due to selective pressure on coliforms, resistant microbial strains are produced that threatens modern medicine where common infections could become more deadly. So, there is an urgent need to develop alternative anti-microbial to replace existing antibiotics for treating a broad spectrum of bacterial diseases. This revived the interest of scientists in phages as an alternative therapy. Phage therapy is defined as a therapeutic use of bacteriophages (natural predators of bacteria) for treating bacterial infections. In the present study pure phage strain was isolated from the untreated sewage water sample and subjected to 10 fold dilution following double agar layer assay to determine phage titer against multi-drug resistant E.coli following host range analysis and stability testing at varying temperature and pH.
Results: Sewage water contains a vast variety of different sizes bacteriophages with clear to diffused boundaries. The pure plaque isolated after repeated plating showed that it was highly specific against tested E. coli strain and could not lyse strains from other species. The titer was calculated to be 109 PFU/ml that remained unchanged at 4°C, 37°C and 50°C temperature. However, at higher pH range phage viability decreases.
Conclusions: In future, it would be expected that the isolated bacteriophages could be characterized and used as a therapeutic potential against multi-drug resistant E.coli that not only attenuate superbug spread but could also replace antibiotics. Beside, isolated phages would be utilized as a bio-component in biosensor development against food borne pathogenic bacteria.
Factors Associated with Immune Discordant Responses in Treated HIV-infected Omani Patients
Authors: Ali Zied Gaifer , Boulassel Mohamed-Rachid 
Published: May 2019

Background:
Despite sustained viral control by antiretroviral therapy (ART), some HIV-infected patients do not recover normal CD4+ T cell counts. This Discordant Immune Response (DIR) increases the risk of opportunistic infections.

Objective:
To evaluate the factors associated with DIR in HIV-infected Omani patients attending public sector clinics.

Methods:
All HIV-infected patients receiving ART with regular follow-up visits were eligible for this study. The DIR group comprised patients on ART for at least two years with plasma HIV viral load < 50 copies/mL and helper CD4+ T cell counts below 350 cells/μl. The Concordant Immune Responses (CIR) group was similar to DIR but with CD4+ T cell counts above 350 cells/μl. Univariate and multivariate analyses using logistic regression models were used to assess the impact of demographic characteristics, clinical, immunological and virological parameters, type of ART regimens, tuberculosis and other opportunistic co-infections on DIR.

Results:
Among 153 enrolled participants, 28 and 76 patients were identified as having DIR and CIR, respectively. The multivariate analysis revealed that the only factors independently associated with DIR after adjustment were age (odds ratio [OR] 1.13; 95% confidence interval [CI] 1.04-1.23), baseline CD4+ T cell count (OR: 0.98; CI: 0.97-0.99) and baseline CD56+ cell count (OR: 0.97; CI: 0.96-0.99).

Conclusion:
Collectively, these findings suggest that a significant proportion of HIV-infected Omani patients develop DIR totaling 27%, and efforts should be made to improve early identification of these patients who tend to experience poor clinical outcomes.
A Digital Intervention for Australian Adolescents Above a Healthy Weight (Health Online for Teens): Protocol for an Implementation and User Experience Study
Authors: Moores Carly Jane , Maeder Anthony , Miller Jacqueline , Prichard Ivanka , Lewis Lucy Kate , Bell Lucinda Kate , Macoustra Aimee , Miller Michelle D 
Published: May 2019

Background
More than one-fourth of Australian adolescents are overweight or obese, with obesity in adolescents strongly persisting into adulthood. Recent evidence suggests that the mid-teen years present a final window of opportunity to prevent irreversible damage to the cardiovascular system. As lifestyle behaviors may change with increased autonomy during adolescence, this life stage is an ideal time to intervene and promote healthy eating and physical activity behaviors, well-being, and self-esteem. As teenagers are prolific users and innate adopters of new technologies, app-based programs may be suitable for the promotion of healthy lifestyle behaviors and goal setting training.

Objective
This study aims to explore the reach, engagement, user experience, and satisfaction of the new app-based and Web-based Health Online for Teens (HOT) program in a sample of Australian adolescents above a healthy weight (ie, overweight or obese) and their parents.

Methods
HOT is a 14-week program for adolescents and their parents. The program is delivered online through the Moodle app–based and website-based learning environment and aims to promote adolescents’ lifestyle behavior change in line with Australian Dietary Guidelines and Australia’s Physical Activity and Sedentary Behaviour Guidelines for Young People (aged 13-17 years). HOT aims to build parental and peer support during the program to support adolescents with healthy lifestyle behavior change.

Results
Data collection for this study is ongoing. To date, 35 adolescents and their parents have participated in one of 3 groups.

Conclusions
HOT is a new online-only program for Australian adolescents and their parents that aims to reduce cardiovascular disease risk factors. This protocol paper describes the HOT program in detail, along with the methods to measure reach, outcomes, engagement, user experiences, and program satisfaction.

Authors: Mohammed Nadheer Jassim 
Published: May 2019

Abstract
We reported in this work the growth of ZnSe nanoparticles thin films deposited on glass substrates were synthesized by a pulsed laser deposition (PLD) method. The as obtained films were characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), UV-VIS Spectrophotometer, and Photoluminescence (PL) spectra. X-ray diffraction study confirmed the transformation the cubic phase of ZnSe nanoparticles into hexagonal phase by increase the laser fluence from (4.77-5.97) J/cm2. The particle size variations were achieved by varying the laser fluence of prepared films. XRD studies and TEM images confirmed the nanometer size was found to lie in the range of 12-80 nm. A UV-VIS study was carried out to measure the band gap of the ZnSe nanoparicles thin films and it showed a blue shift with respect to the bulk value. The PL spectra at room temperature (300K) of the films showed the decrease of maximum values at at 522 nm( 2.379), 521 nm (2.3838) and 520 nm (2.3882 eV) for the laser fluence (4.77, 5.57 and 5.97 J/cm2), respectively. We assigned the variation due a larger number of non-radiative recombination centers appears in the films.
