AbstractBacteria have a fundamental role in determining the fitness of grapevine, the composition of grapes and the features of wines but at present, little information is available. In this work, the bacteria colonizing the different portions of grapevine (bark, leaves and grapes) were explored in the vineyards of the Alpine region of Trentino, considering the impact of different environmental and agronomical variables. The vineyards included in the work were selected based on their different geographical positions (altitude) and grapevine training systems in order to explore the whole variability of the grapevine ecosystem. Moreover, the surface amount of copper was measured on grapes and leaves during the vegetative growth. Bacterial analysis, performed using plate counts and Illumina MiSeq, revealed an increase in the concentration of grape bacteria proportional to the progress of the ripening stage. Conversely, the peak of bacterial concentration onto leaf and bark samples occurred in August, probably due to the more favourable environmental conditions. In bark samples, the bacterial microbiota reached the 7 log CFU/cm2, while 6 log UFC/g were measured in grape samples. A remarkable biodiversity was observed, with 13 phyla, 35 classes, 55 orders, 78 families and 95 genera of bacteria present. The presence of some taxa (Alphaproteobacteria, Desulfovibrionaceae, Clostriadiales, Oscillospira, Lachnospiraceae and Bacteroidales) was ubiquitous in all vineyards, but differences in terms of relative abundance were observed according to the vegetative stage, altitude of the vineyard and training system. Bacteria having oenological implication (Lactobacillus, Pediococcus and Oenococcus) were detected in grape samples collected in August, in low abundance. The data revealed a complex bacterial ecosystem inside the vineyard that, while maintaining common traits, evolves according to environmental and agronomical inputs. This study contributes to define the role of bacteria in the complex balance established in each vineyard between human actions and agricultural environment, known as terroir.

Abstract Bacterial microbiota has a fundamental role in determining the fitness of a grapevine, the composition of grapes and the features of wines but, at present, little information is available. In this work, the bacterial microbiota that colonizes the different portions of a grapevine (bark, leaves and grapes) was explored in the vineyards of the Alpine region of Trentino, considering the impact of different environmental and agronomical variables. The six vineyards included in the work were identified considering different geographical positions, vine training systems and agronomical approaches, to explore the whole variability of the vine ecosystem. Moreover, the surface amount of copper was measured on grapes and leaves during the vegetative growth, to test its relation with microbiota development. Microbiological assays, performed using plate counts and Illumina MiSeq, started in May until October revealing an increase in the concentration of grape microbiota proportional to the ripening. Conversely, the peak of bacterial concentration onto leaves and bark occurred in August, probably due to the more favorable environmental conditions. In bark samples, the microbiota reached the 7 log UFC/cm2, while 6 log UFC/g were measured in grape samples. A remarkable biodiversity was observed, with 47 genera/species of bacteria present. The presence of the main microbial groups (Alphaproteobacteria, Desulfovibrionaceae, Clostriadiales, Oscillospira, Lachnospiraceae and Bacteroidales) was ubiquitous in vineyards, but differences in terms of relative abundance were observed according to the period, altitude of vineyard and training system. Bacteria having oenological implication (Lactobacillus, Pediococcus and Oenococcus) were detected only in grape samples collected in August. The data revealed a complex bacterial ecosystem inside the vineyard that, while maintaining common traits, evolves according to environmental and agronomical inputs. This study contributes to define the role of bacteria in the complex balance established in each vineyard between human actions and agricultural environment, known as terroir.

In the course of the research, we examined the impact of the selection and training system of a Hungarian automotive company on organizational performance, which together ensure the future development of the company. It contributes to the optimization of sales, purchasing and logistics processes, ensures customer satisfaction and the success of the company. In this fast-paced and globalized world, it is essential for companies to be aware that one of the most important factors of production is human resources themselves, whose proper selection and training are a key element in maintaining and developing economic competitiveness. Human resources play the biggest role in the operation of an economic organization. Process quality and process orientation reduce costs, increase profitability, and improve processes to always meet growing requirements. This is the basis of the quality strategy. Therefore, it consistently applies preventive quality assurance methods, learns from failures, eliminates the causes of mistakes without delays and transfers its experience to all areas of the company for preventive action. It is customer-oriented and strives for excellence in all areas, and thus makes it an obligation for everyone to aim for the highest level of customer service. Due to the special peculiarities and characteristics of the labor force, it cannot be compared to any of the production resources. Taking this as a basis, the human resource management used to be more of a functional purpose, while in recent decades human factors have become an essential source of competitiveness. The market operation and performance of an organization depends significantly on how we can select the most suitable workforce. We need to see what the strategic points that determine the role of HR are, and we are also looking for the answer in which direction the needs, expectations and professionalism given by the generational difference move the activities of human resources. The aim of the research is to get an answer to how the employees of one of the leading Hungarian players in the automotive industry perceive the importance of the selection and training of the workforce in maintaining and improving competitiveness. To this end, we used a semi-structured interview, with the help of which we evaluated the current selection and training processes in the light of competitiveness and made suggestions for the improvement and refinement of these processes.

This study aimed to assess the impact of two soil managements and training systems on yield and wine aroma compounds of Negroamaro variety grown in a warm climate region (southern Italy). Cover crop (CC) and soil tillage (ST) as soil management, whilst bilateral Guyot (BG) and monolateral Guyot (MG) as training systems were compared. Free and bound volatile fractions were evaluated by GC-MS. ST and CC as well as BG and MG significantly affected yield parameters. In particular, yield was higher in ST and BG than in CC and MG, respectively; moreover, it was found to be positively influenced by interaction between BG and ST. Regarding aroma compounds, significant interactions between soil management and training system factors were observed. In case of free volatiles, the most positive interaction was found between BG and ST, whereas, for bound volatiles, the best interaction was represented by MG with both soil tillage and cover crop. Vine leaf area and development over vine growth stages along with water stress levels played an important role in determining the aroma profile as well as yield parameters. In conclusion, the training system significantly interacted with soil management and affected most of important aroma compounds in Negroamaro wine.

This paper looks to expand on the INEC 2016 paper ‘The future role of virtual reality within warship support solutions for the Queen Elizabeth Class aircraft carriers’ presented by Ross Basketter, Craig Birchmore and Abbi Fisher from BAE Systems in May 2016 and the EAAW VII paper ‘Testing the boundaries of virtual reality within ship support’ presented by John Newell from BAE Systems and Simon Luck from BMT DSL in June 2017. BAE Systems and BMT have developed a 3D walkthrough training system that supports the teams working closely with the QEC Aircraft Carriers in Portsmouth and this work was presented at EAAW VII. Since then this work has been extended to demonstrate the art of the possible on Type 26. This latter piece of work is designed to explore the role of 3D immersive environments in the development and fielding of support and training solutions, across the range of support disciplines. The combined team are looking at how this digital thread leads from design of platforms, both surface and subsurface, through build into in-service support and training. This rich data and ways in which it could be used in the whole lifecycle of the ship, from design and development (used for spatial acceptance, HazID, etc) all the way through to operational support and maintenance (in conjunction with big data coming off from the ship coupled with digital tech docs for maintenance procedures) using constantly developing technologies such as 3D, Virtual Reality, Augmented Reality and Mixed Reality, will be proposed.  The drive towards gamification in the training environment to keep younger recruits interested and shortening course lengths will be explored. The paper develops the options and looks to how this technology can be used and where the value proposition lies.

AbstractThe Republic of Serbia must make significant efforts to promote and exploit renewable energy sources and increase energy efficiency in all energy sectors to ensure energy security and economic competitiveness, reduce the negative impact on the environment from energy production and use, and contribute to global efforts to reduce greenhouse gases. Within the paper several issues of integration of recently realized CHP plant are introduced and discussed. Firstly, the legal and energy policy issues in the Republic of Serbia regarding connecting CHP to the grid are presented. The challenges and technical solutions for CHP connection to the grid, as well as power quality issues and the role of the CHP plant during the restoration of power supply during the maintenance of the substation and unplanned loss of high voltage supply, are presented and discussed. Finally, the impact of prospective massive integration of CHP on the energy balance and CO2 emission reduction in the province of Vojvodina in Serbia is investigated and discussed. Since it is the first CHP plant realized in Serbia, it is crucial that experience be shared to all potential stakeholders in the future energy efficiency projects.

Background: Men who develop behaviors connected with the model of hegemonic masculinity present several health problems. Previous research has shown the types of problems that men commonly suffer in this regard such as chronic diseases, dietary disorders, and traffic accidents. To combat and overcome this situation, several campaigns, policies and recommendations have been undertaken, and consequently, their influence has been analyzed. However, there have been few investigations into the role of men’s friendship in the reduction of these physical health problems. The findings presented in this article are focused on this issue, illustrating the impact of male friendship on the shaping of healthy behaviors. Methods: Drawing upon a qualitative-based methodology articulated in a case study of the Men in Dialogue association, located in Spain, the study has followed the premises of the communicative approach, a total of 15 structured online open-ended questionnaires have been performed and analyzed. The median age of the participants is 37.5 years. Results: The findings show how men involved in Men in Dialogue are promoting a kind of masculine friendship that is improving men’s emotional well-being and, consequently, their physical health.

This article aims to explore the perceptions of banana farms managers towards environmental sustainability practices through the impact of innovation, adoption of information systems, and training employees through a case study in the province of El Oro (Ecuador). Furthermore, the paper assesses how farmers’ perceptions could guide public policy incentives. PLS-Structural Equation Modeling are used as the framework by which the constructs is represented within the model. The model explained 59% of the environmental sustainability practices of Ecuadorian banana farms. The results indicate that environmental sustainability practices were positively influenced mainly by training employees, innovation, and adoption of information systems. Additionally, both the adoption of information systems and training employees indirectly influenced sustainable practices through innovation as a mediator. We may conclude that in the Ecuadorian banana farms, changes in environmental practices are derived from innovation strategies as an axis of development of useful information and training employees in public policies.
